[Chevron logo] [Texaco logo] TO CHEVRON AND TEXACO STOCKHOLDERS: A PROPOSAL TO MERGE OUR COMPANIES The Boards of Directors of Chevron Corporation and Texaco Inc. have approved a merger agreement that provides for the combination of our two companies. Texaco will join the Chevron group and Chevron will be renamed ChevronTexaco Corporation. We believe ChevronTexaco will rank with the world's largest and most competitive international energy companies and will create greater value for stockholders than either Chevron or Texaco could have achieved on its own. If the merger is completed, holders of Texaco common stock will receive 0.77 shares of ChevronTexaco common stock for each share of Texaco common stock they hold. Chevron stockholders will continue to own their existing shares after the merger. Chevron stock, after the closing of the merger, will be ChevronTexaco stock. ChevronTexaco will issue approximately ____ million shares of ChevronTexaco common stock to Texaco stockholders in the merger, based on the outstanding shares of Texaco on _______________, 2001. These shares will represent approximately ___ percent of the outstanding ChevronTexaco common stock after the merger. Shares of ChevronTexaco common stock will be listed on the New York Stock Exchange under the ticker symbol "CHV." The value of the ChevronTexaco common stock Texaco stockholders will receive in the merger is currently unknown and may be less than the current market value of Chevron common stock. The Board of Directors of Texaco recommends that its stockholders approve the merger and the merger agreement. Therefore, we are asking the Texaco stockholders to vote for this proposal. The Board of Directors of Chevron recommends that its stockholders approve the issuance of common stock to Texaco stockholders and the amendment of Chevron's restated certificate of incorporation to change its name to ChevronTexaco Corporation. Therefore, we are asking the Chevron stockholders to vote for these proposals. We cannot complete the merger unless Texaco stockholders approve the merger and Chevron stockholders approve the common stock issuance. Your vote is very important. We encourage you to read this entire document, including the discussion of risks associated with the merger beginning on page 13, carefully before voting.

SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA How We Prepared the Financial Statements We are providing the following information to aid you in your analysis of the financial aspects of the merger. We derived this information from the audited financial statements of Chevron and Texaco for the years 1996 through 2000. The financial statements also reflect the consolidation of entities commonly owned by Chevron and Texaco, primarily Caltex. The information is only a summary, and you should read it together with our historical financial statements and related notes contained in the annual reports and other information that we have filed with the SEC and incorporated by reference. See "Where You Can Find More Information" on page 85. Pooling-of-Interests Accounting Treatment We expect that the merger will be accounted for as a "pooling-of-interests." This means that, for accounting and financial reporting purposes, we will treat our companies as if they had always been combined. For a more detailed description of pooling-of-interests accounting, see "The Merger Transaction--Accounting Treatment" on pages 27 and 28. We have presented unaudited pro forma condensed combined financial information that reflects the pooling-of-interests method of accounting to give you a better picture of what our businesses might have looked like had they been combined since January 1, 1998. We prepared the unaudited pro forma condensed combined statements of income and unaudited pro forma condensed combined balance sheet by adding or combining the historical amounts of each company. The accounting policies of Chevron and Texaco are substantially comparable. Consequently, we did not make adjustments to the unaudited pro forma condensed combined financial statements to conform the accounting policies of the combining companies. Additionally, we did not make adjustments to the unaudited pro forma condensed combined financial statements to reflect the effect of any asset dispositions that may be required by order of regulatory agencies. The companies may have had different financial results had they always been combined. You should not rely on the unaudited pro forma condensed combined financial information as being indicative of the historical results that would have been achieved had our companies always been combined or of the future results that we will experience after the merger. See "Unaudited Pro Forma Condensed Combined Financial Statements" on page 59 for more information. Merger-Related Expenses We estimate that merger-related fees and expenses, consisting primarily of SEC filing fees, fees and expenses of investment bankers, attorneys and accountants, and financial printing and other related charges, will total approximately $125 million. See note 5 on pages 61 and 62 for more information about merger-related expenses. Integration-Related Expenses Though not yet fully quantified, significant costs will be incurred for employee severance and other integration-related expenses, including the elimination of duplicate facilities, operational realignment and workforce reductions. These expenditures are necessary to reduce the costs of ongoing operations and to operate more effectively. These amounts will be charged to operations in the appropriate periods and, therefore, are not reflected in the unaudited pro forma condensed combined financial statements. See note 5 on pages 61 and 62 for more information about integration-related expenses. Periods Covered The unaudited pro forma condensed combined statements of income combine Chevron's and Texaco's results for the years ended December 31, 2000, 1999 and 1998, giving effect to the merger as if it had occurred on January 1, 1998. The unaudited pro forma condensed combined balance sheet combines the balance sheets of Chevron and Texaco as of December 31, 2000, giving effect to the merger as if it had occurred on December 31, 2000. -8-

Selected Unaudited Pro Forma Combined Financial Data The following selected unaudited pro forma combined financial data have been derived from and should be read together with the unaudited pro forma condensed combined financial statements and related notes on pages 55 through 62. This information is based on the historical consolidated balance sheets and related historical consolidated statements of income of Chevron and Texaco, giving effect to the merger using the pooling-of-interests method of accounting for business combinations. The financial statements also reflect the consolidation of entities commonly owned by Chevron and Texaco, primarily Caltex. We did not make adjustments to the unaudited pro forma condensed combined financial statements to reflect the effect of any asset dispositions that may be required by order of regulatory agencies. This information is included for illustrative purposes only. The financial results may have been different had the companies actually been combined during the periods. You should not rely on the selected unaudited pro forma combined financial data as being indicative of the historical results that would have been achieved had the companies always been combined or the future results that the combined company will experience after the merger.

Comparative Per Share Data Set forth below are the net income, cash dividends and book value per common share data separately for Chevron and Texaco on a historical basis, for ChevronTexaco on a pro forma combined basis and on a pro forma combined basis per Texaco equivalent share. The exchange ratio of the business combination is 0.77 shares of ChevronTexaco common stock for each share of Texaco common stock. The ChevronTexaco pro forma data was derived by combining the historical consolidated financial information of Chevron and Texaco, using the pooling-of-interests method of accounting for business combinations as described under "Unaudited Pro Forma Condensed Combined Financial Statements" beginning on page 55. The Texaco equivalent-share pro forma information shows the effect of the merger from the perspective of an owner of Texaco common stock. The information was computed by multiplying the ChevronTexaco pro forma information by the exchange ratio of 0.77. You should read the information below together with the historical financial statements and related notes contained in the annual reports and other information filed with the SEC and incorporated by reference. See "Where You Can Find More Information" on page 85. The unaudited pro forma combined data below is for illustrative purposes only. The financial results may have been different had the companies actually been combined during the periods.

RISK FACTORS In addition to the other information that we have included and incorporated by reference in this joint proxy statement/prospectus, you should carefully read and consider the following factors in evaluating the proposals to be voted on at the special meetings of Chevron and Texaco stockholders. The value of the merger consideration that Texaco stockholders will receive may decline and will depend on the market value of Chevron common stock at the effective time of the merger. In the merger, Texaco stockholders will receive 0.77 shares of Chevron common stock in exchange for each of their shares of Texaco common stock. The market value of Chevron common stock is likely to vary between the date of this proxy statement/prospectus and the effective time of the merger and may decline. Because the value of the merger consideration depends on the market value of Chevron common stock at the effective time of the merger, the value of the merger consideration that Texaco stockholders will receive in the merger cannot now be determined. This market value may be less than or greater than $____ per share of Texaco common stock, which is the value of the merger consideration based upon the closing Chevron common stock price on the NYSE of $_____ on ________ __, 2001, the last full trading day prior to the date of this joint proxy statement/prospectus. If the market value of Chevron common stock declines prior to the effective time of the merger, then the value of the merger consideration to be received by the holders of Texaco common stock in the merger will correspondingly decline. The merger agreement does not allow Texaco to terminate the merger agreement because of a decline in the price of Chevron common stock. After the merger, the market value of ChevronTexaco common stock will undoubtedly also change over time. Detailed information about various factors which may contribute to changes in securities prices of Chevron and Texaco is contained in their filings with the SEC. Because the exchange ratio is not subject to adjustment for changes in the price of Chevron or Texaco common stock, the fixed exchange ratio may be less favorable to Chevron or Texaco stockholders on the closing date than it was when the merger agreement was approved. Texaco stockholders will receive 0.77 shares of Chevron common stock for each of their shares of Texaco common stock on the closing date of the merger. This exchange ratio will not be adjusted for changes in the market price of Chevron common stock or Texaco common stock. In the event the value of Chevron common stock declines in relation to the value of Texaco common stock prior to the closing date, the fixed ratio will be less favorable to Texaco stockholders than it was at the time Credit Suisse First Boston rendered its opinion on the exchange ratio to Texaco's board of directors and the Texaco board approved the merger. On the other hand, in the event the value of Chevron common stock increases in relation to the value of Texaco common stock prior to the closing date, the fixed ratio will be less favorable to Chevron stockholders than it was at the time Lehman Brothers rendered its opinion on the exchange ratio to Chevron's board of directors and the Chevron board approved the merger. Any delay in the consummation of the merger could diminish the benefits of the merger. The merger is conditioned upon the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Act. In addition, other filings with, notifications to and authorizations and approvals of, various governmental agencies in numerous other countries with respect to the merger relating primarily to antitrust issues must be made and received prior to the consummation of the merger. We cannot predict how long it will take for us to satisfy regulatory requirements. A long delay will have an adverse financial impact on ChevronTexaco to the extent that cost savings and other benefits that we expect from the merger are foregone or deferred. Divestitures or other restrictions ordered by government agencies may have an adverse effect on the combined company. As in any large transaction, it is possible that governmental agencies may seek restrictions on the combined operations of Chevron and Texaco, including divestitures, as a condition to obtaining the required regulatory approvals. Any such restrictions on operations or divestitures could diminish the benefits of the merger to Chevron and Texaco to the extent they adversely affect the operations of the combined company. In particular, we anticipate -13-

that divestiture of Texaco's investments in its United States downstream affiliates, Equilon and Motiva, will be required as a condition of approval of the merger. We have assumed their divestiture in estimating merger synergies. However, under the circumstances of a required divestiture, the terms of which have not yet been negotiated with regulatory authorities, we may realize substantially less value for these assets than if they were retained for sale without conditions imposed on the timing and manner of sale. Texaco has held discussions with Shell and Saudi Refining, its joint venture partners in Equilon and Motiva, regarding such a transaction. However, we cannot predict what value we might receive in exchange for these interests in the event such a disposition is ordered. If we are required to divest these or any other assets on unfavorable terms, the combined company may be adversely affected. The deal-protection provisions of the merger agreement may deter alternative business combinations and could negatively impact the stock price of either company in the event it terminates the merger agreement. As a result of the provisions of the ChevronTexaco agreements, it is possible that a third party who might be interested in submitting a business combination proposal to either or both of Chevron and Texaco will be discouraged from doing so. Any such proposal might be advantageous to the stockholders of Chevron and Texaco relative to the terms and conditions of the transaction described in this joint proxy statement/prospectus. In particular, the termination fee provisions of the merger agreement and the reciprocal stock options Chevron and Texaco have granted each other may deter third parties from proposing alternative business combinations that might result in greater value to stockholders than the merger. In addition, in the event the merger is terminated by Chevron or Texaco in circumstances that obligate it to pay a termination fee to the other company, the other company's stock option will become exercisable. If this occurs, the terminating company's stock price may decline as a result of the termination fee and because the existence of the stock option could prevent it from accounting for alternative business combinations as a pooling-of-interests. See "The Merger Agreement--Termination of the Merger Agreement" and "--Stock Option Agreements" for more information. The anticipated benefits of the merger may be more costly to realize than expected or may not be realized within the anticipated time frame or at all. The success of the merger will depend, in part, on the ability of ChevronTexaco to realize the anticipated synergies, cost savings and growth opportunities from integrating the businesses of Chevron and Texaco. If the combined company is not able to realize the anticipated synergies, cost savings and growth opportunities, the market value of ChevronTexaco stock may be adversely impacted. ChevronTexaco's success in realizing these synergies, cost savings and growth opportunities, and the timing of this realization, depends on the successful integration of Texaco's operations into Chevron. Even if Chevron and Texaco are able to integrate their business operations successfully, this integration may not result in the realization of the full benefits of the synergies, cost savings and growth opportunities that both companies currently expect to result from this integration or that these benefits will be achieved within the anticipated time frame. For example, the elimination of significant duplicative costs may not be possible or may take longer than anticipated; the benefits from the merger may be offset by costs incurred in integrating the companies; and regulatory authorities may impose adverse conditions on the combined businesses, such as divestiture of product lines, in connection with granting approval of the merger. -14-

THE MERGER General Chevron's board of directors is using this joint proxy statement/prospectus to solicit proxies from the holders of Chevron common stock for use at the Chevron meeting. Texaco's board of directors is also using this document to solicit proxies from the holders of Texaco common stock for use at the Texaco meeting. Chevron Proposals At the Chevron meeting, holders of Chevron common stock will be asked to vote upon: o approval of the proposed issuance of ChevronTexaco common stock in connection with the merger; and o approval of the amendment of Chevron's restated certificate of incorporation to change Chevron's name to "ChevronTexaco Corporation." Texaco Proposals At the Texaco meeting, holders of Texaco common stock will be asked to vote upon approval and adoption of the merger agreement and the merger. Background of the Merger Against a backdrop of industry consolidations, Chevron and Texaco entered into a confidentiality agreement on February 5, 1999 for the purpose of facilitating discussions concerning a potential business combination. These discussions took place principally between Kenneth Derr, who was then the Chevron Chairman and CEO, and Peter Bijur, who was then the Texaco Chairman and CEO. On May 28, 1999, Chevron proposed a transaction in which each Texaco share would be exchanged for 0.765 of a Chevron share. The discussions were terminated by Texaco on June 2, 1999 following press reports that merger negotiations had occurred. In deciding to terminate these discussions, Texaco's board concluded that the proposed combination with Chevron was not compelling in terms of creating value for Texaco's stockholders. The board's decision was based upon its evaluation at that time of the price and terms being offered, particularly in the context of Texaco's expectation of its ability to create stockholder value by executing its strategic plan. The board concluded at that time that Texaco could satisfactorily grow shareholder value as an independent entity. Chevron expressed its disappointment at the termination of merger discussions, but did not amend its proposal or otherwise seek to keep the discussions alive. In February 2000, Chevron and Texaco undertook a joint study of their investment in Caltex Corporation. Mr. Bijur and David O'Reilly, who had succeeded Mr. Derr as Chevron's Chairman and CEO, jointly oversaw the review. On May 19, 2000, Mr. Bijur met privately with Mr. O'Reilly in San Francisco to discuss the Caltex study and to schedule a further meeting on that subject for June 2, 2000. In the course of the private meeting, Mr. Bijur indicated a willingness to begin new discussions with Chevron regarding a potential business combination. Following the May 19, 2000 meeting, Mr. O'Reilly engaged Chevron's staff to work with outside financial and legal advisors to develop a recommendation to be presented to Chevron's board of directors at its meeting on May 31, 2000. During the week of May 22, 2000, John Watson, a Chevron Vice President, and Bill Wicker, a Texaco Senior Vice President, together with other Chevron and Texaco employees, had three conference calls to discuss potential synergies in a Chevron-Texaco business combination. At the board meeting, Mr. O'Reilly sought and obtained approval to negotiate a combination with Texaco. Messrs. O'Reilly and Watson met with Messrs. Bijur and Wicker in New York on June 2, 2000. At the meeting, Mr. O'Reilly outlined terms of a proposed business transaction. Pursuant to Chevron's proposal, Texaco would become a Chevron subsidiary through a merger in which each Texaco share would be exchanged for 0.75 share of Chevron. Chevron would rename itself ChevronTexaco, but remain headquartered in San Francisco. Texaco Chairman and CEO Peter Bijur would become a Vice Chairman of ChevronTexaco. The transaction would -16-

be conditioned on pooling accounting, and regulatory and stockholder approvals. Mr. Bijur, in response to the terms outlined by Mr. O'Reilly, then proposed an exchange ratio in the range of 0.76 and 0.77. Mr. O'Reilly indicated that Chevron could get within that range. A working-level meeting was scheduled to explore issues arising from this proposal. On June 7, 2000, Mr. Watson and Mr. Wicker met in Dallas, accompanied by a number of internal and external advisors. The participants discussed possible regulatory issues arising out of a business combination including what should happen in the likely event that antitrust authorities would not permit the combined company to retain both Chevron's and Texaco's United States "downstream" (petroleum refining and marketing) businesses. Chevron's U.S. downstream business is wholly-owned, while Texaco's consists principally of interests in two joint venture companies, Equilon Enterprises LLC and Motiva Enterprises LLC. Equilon is a joint venture with Shell Oil Company and Motiva is a joint venture with Shell and Saudi Refining, Inc. Chevron and Texaco ultimately concluded that it would likely be necessary for Texaco to divest its interests in both Equilon and Motiva to satisfy the competitive concerns that regulatory authorities would likely raise. The conclusion that a divestiture of the U.S. refining, marketing and transportation businesses would likely be required was formulated after reviewing with counsel potential antitrust objections to the merger, based on FTC reviews of the BP/Amoco, BP/Arco and Exxon/Mobil transactions and the market concentration that the FTC would likely deem to result from the merger. Because ChevronTexaco would own a substantial share of Equilon and Motiva, the parties expected that the FTC would likely analyze the merger as the combination of Chevron's downstream business with the Equilon and Motiva downstream businesses, even if those operations remain operationally separate. In prior industry transactions, the FTC had been concerned that the divested assets remain viable competitors in the marketplace. Since a divestiture of Texaco's ownership in Equilon and Motiva would be of equity interests, not of isolated assets or business lines, the parties expected that this divestiture would address these concerns. In addition, such a divestiture would leave intact Chevron's own refining and marketing system, a strategic consideration for Chevron. On June 12, 2000, Mr. O'Reilly, accompanied by an outside legal advisor, met in New York with Mr. Bijur, accompanied by Mr. Wicker and Deval Patrick, then Texaco's general counsel. The participants reviewed the progress made at the June 7th meeting, and continued to discuss the proposed transaction. Texaco representatives expressed concerns about the expected complexity of the transaction and the length of time it might take to complete, and also expressed a desire to discuss with Shell the potential effect of a merger on Equilon and Motiva. Mr. Bijur also indicated nevertheless that he would discuss the Chevron proposal with the Texaco board later that month. On June 23, 2000, Texaco management reviewed for the Texaco board the consolidations in the petroleum industry and the decreasing opportunities Texaco might have to acquire other oil and gas or energy companies. Management reviewed its long-term strategic plan and described the factors that could cause Texaco to succeed or fail to achieve its strategic objectives. Management also reviewed Texaco's prospects as an independent company as well as the strategic rationale for a merger with Chevron. Management described the terms of the Chevron proposal and presented a preliminary financial analysis relating to the combination. On the basis of its analysis of these factors, the board indicated a willingness to continue merger discussions with Chevron. Following the Texaco board meeting, Mr. Bijur telephoned Mr. O'Reilly to report that the Texaco board had expressed a desire for additional information regarding the potential divestitures of the joint ventures and had recommended that Mr. Bijur meet with Shell. On June 26, 2000, legal representatives of Chevron and Texaco had a teleconference to discuss issues related to the joint ventures. Mr. O'Reilly reported the developments to the Chevron Board at its meeting on June 28, 2000. On July 3, 2000, Mr. Bijur and Glenn Tilton, then a Senior Vice President of Texaco, met in London with Mark Moody-Stuart, Chairman of the Royal Dutch/Shell Group and Paul Skinner, CEO of Oil Products for Shell. They discussed, among other things, the fact that Texaco was considering a merger which would likely require divestiture of its interests in the joint ventures and whether, under those circumstances, Shell might be interested in acquiring those interests. Representatives of Texaco and Chevron and some of their outside advisors met on July 13, 2000 in New York to discuss potential alternative approaches to handling the issues relating to Equilon and Motiva. At the -17-

meeting, representatives of Texaco proposed the use of a liquidating trust to hold the Equilon and Motiva interests if, as expected, they became the subject of a divestiture order as a result of antitrust review of the transaction. On July 27, 2000, representatives of Texaco and Shell met in New York to discuss specifically the terms upon which Shell might acquire Texaco's interest in Equilon (it was agreed that there would be no conversations regarding Motiva without Saudi Refining, Inc.'s participation). On August 16, 2000, Mr. Bijur met with Mr. Abdullah S. Jum'ah, President & CEO of Saudi Arabian Oil Company, an affiliate of Saudi Refining, Inc. Mr. Bijur told Mr. Jum'ah that Texaco was contemplating a transaction which might affect Texaco's interests in Motiva and Equilon. He discussed the fact that a preliminary meeting had been held with Shell regarding possible alternatives regarding Equilon and suggested a three way meeting. On September 6, 2000, Messrs. Bijur and O'Reilly met to consider further the terms of the proposed merger and discussed an exchange ratio of .77 of a Chevron share for each Texaco share along with the other terms that had been previously discussed. Following the meeting, Mr. O'Reilly instructed the Chevron staff and outside advisors to prepare draft agreements embodying the terms discussed at the meeting on September 6, 2000. On September 9, 2000, Mr. Bijur met with Mr. Jum'ah and Mr. Moody-Stuart in Saudi Arabia. During the course of that meeting it was agreed that Texaco and Shell would try to come to agreement regarding Equilon assuming Texaco were to divest its interests in Equilon and Motiva. Meanwhile, Saudi Refining, Inc. and Shell would meet to discuss views regarding Motiva going forward, with the intent being that once a basis had been agreed for Equilon, the three companies would move on to address Motiva. On September 15, 2000, the Texaco board of directors met and Mr. Bijur described his discussions with Chevron's representatives with respect to the principal terms of the proposed merger. Mr. Bijur also described the status of discussions with the Equilon and Motiva joint venture partners. Following the meeting, Mr. Bijur telephoned Mr. O'Reilly to indicate that the Texaco board had authorized management to enter into negotiations with Chevron and requested that Chevron tender draft agreements. Chevron's legal advisers then circulated to Texaco a draft merger agreement embodying the terms that had been discussed and other terms customary to merger agreements of this type, including forms of common deal protections such as a "no shop" clause and breakup fees. Chevron also requested that Texaco grant Chevron an option to purchase the maximum number of shares of Texaco stock that Texaco could issue without stockholder approval. A draft stock option agreement with these terms was included in the package circulated to Texaco. On September 20, 2000, Chevron sent Texaco a list of requested due diligence materials. Based on this list, the parties exchanged background information on various aspects of their businesses. In essence, these materials confirmed assessments obtained from the publicly available information that had been used by both sides and their advisers in evaluating the potential transaction or estimates of potential merger synergies. On September 21, 2000, representatives of Chevron and its legal advisors met in New York with representatives of Texaco and its legal advisors. At the meeting, the Texaco representatives provided preliminary comments on the initial draft agreements. To help provide certainty of closing, Texaco wanted Chevron to agree that the Texaco companies holding the joint venture interests could be placed in a liquidating trust if divestiture were mandated but no agreement had been reached for the disposition of the joint venture interests. Texaco also expressed concerns about granting a nonreciprocal stock option to Chevron. On September 26, 2000, at a meeting of the Chevron board of directors in Caracas, Venezuela, the status of negotiations was discussed and Lehman Brothers advised the board that as of that date the proposed exchange ratio was fair, from a financial point of view, to Chevron. On September 29, 2000, Texaco's legal advisors distributed to Chevron and its legal advisors an initial draft of a trust agreement to address Texaco's concerns about Equilon and Motiva. -18-

On October 3, 2000, the respective legal teams met again in New York to discuss the various draft agreements in detail. Texaco's counsel provided more detailed comments on the earlier Chevron drafts and further explained Texaco's position on the liquidating trust. Revised drafts of the merger and stock option agreements were prepared and distributed by Chevron's counsel on October 6, 2000. The revised drafts incorporated the concept of the liquidating trust and also provided for reciprocal stock options. On October 10, 2000, Texaco and Chevron executives, other employees, counsel and financial advisors met by teleconference for approximately half a day to conduct confirmatory due diligence for the transaction. The session was primarily in question-and-answer format, and covered the key aspects of the business of each company, including corporate structure, the exploration and production businesses, the refining and marketing businesses, the gas and power businesses, a financial review, a discussion of material pending legal proceedings and a description of human resources matters. Some follow-up questions, mostly related to the international upstream business, were responded to in the following days. Beginning on October 11, 2000, counsel for Chevron and Texaco met again in New York to review and negotiate the draft agreements. During these meetings, numerous points still outstanding relating to the respective representations, warranties, covenants and agreements of Chevron and Texaco were resolved subject to ultimate approval of the boards of directors of Chevron and Texaco. Revised drafts were prepared, circulated and reviewed by counsel during the remainder of the week. On October 14, 2000, Mr. O'Reilly and Mr. Bijur, together with other senior executives of Chevron and Texaco and their respective staff and advisors, met in New York to review merger communications issues. On the same day and through the following morning, counsel to Chevron and Texaco resolved remaining documentary issues. On October 15, 2000, the board of directors of Texaco held a special meeting to consider the proposed transaction. At this meeting, the board reviewed the progress of the negotiations with Chevron as well as the status of discussions with the Equilon and Motiva joint venture partners. Texaco's legal advisors discussed with the board its fiduciary duties under Delaware law and described the terms of the proposed merger agreement, stock option agreements and trust agreement and responded to questions from directors. Texaco's financial advisor, Credit Suisse First Boston, presented a summary of its financial analyses relating to the proposed merger and delivered its opinion that as of that date the proposed exchange ratio was fair to the holders of Texaco common stock from a financial point of view. Following discussions, the board approved the merger agreement and the related agreements and the transactions contemplated by those agreements and resolved to recommend that its stockholders vote to approve the merger agreement. On the same day, the Chevron board met in San Francisco, with Mr. O'Reilly participating by telephone from New York. The board reviewed information that had been provided to the directors in advance of the meeting by Chevron's counsel and financial advisors, and both counsel and financial advisors were present with Mr. O'Reilly and provided additional advice to the board. Mr. O'Reilly reviewed the course of the merger negotiations and led the discussion of the issues related to the merger. At the meeting, Lehman Brothers delivered its opinion that as of that date the exchange ratio was fair, from a financial point of view, to Chevron. Following the discussion, the board approved the entry into the merger agreement and related transaction documents and resolved to recommend that its stockholders vote to approve the issuance of common stock and the change in the company's name under the merger agreement. Following the Texaco and Chevron board meetings, Mr. O'Reilly and Mr. Bijur, accompanied by other senior executives of Chevron and Texaco, and by their respective legal and financial advisors, met in New York on October 15, 2000 to execute the merger agreement and related transaction documents. Our Reasons for the Merger By joining Chevron and Texaco we will create a U.S.-based, global enterprise that we believe will rank with the world's largest and most competitive international energy companies and will be highly competitive across all energy sectors. As separate companies, Chevron and Texaco are leading energy companies with positive -19-

prospects for the future; however, we believe that a combined Chevron and Texaco will create greater value for the stockholders of both companies than we could deliver as separate companies. Simply stated, and as described in more detail below, we believe that by combining Chevron and Texaco we can save money, increase profits and returns and reduce risk. In addition, the combined company will have greater financial, technological, and human resources. All of this will better position us to compete effectively with our global competitors. The benefits that we expect to realize by combining Chevron and Texaco depend, in part, on our ability to successfully integrate the operations of the two companies. It is possible that the expected benefits may not be fully realized or that these expected benefits may not be realized in a timely or cost-effective manner. You should review the risk factors beginning on page 13 for a discussion of the risks associated with ChevronTexaco not fully or timely realizing the expected benefits of the merger. ChevronTexaco will be positioned for stronger financial returns than could be achieved by either Chevron or Texaco on its own. We believe that these stronger returns will be achieved partly through significant cost savings, but also because we will be able to pursue our business from a much broader base of quality assets, skills and technology. ChevronTexaco will have the financial resources to fund the best growth opportunities of both companies. As a result, we believe this merger will help us accomplish our combined goal: to be first in our industry in total stockholder return. Chevron has set a goal of being number one in its industry peer group in total stockholder return for the five-year period January 1, 2000 through December 31, 2004. For the period beginning January 1, 2000 through October 15, 2000, the day prior to the merger announcement, Texaco and Chevron ranked third and fourth, respectively, among their industry peer group which includes Royal Dutch/Shell, ExxonMobil and BP Amoco. For the period beginning January 1, 2000 through March 31, 2001, Texaco and Chevron ranked first and second, respectively, in total stockholder return among the same peer group. The experience of the last several years has demonstrated, in the opinion of Chevron's and Texaco's management, that investors believe that the so-called "super-majors," Royal Dutch/Shell, ExxonMobil and BP Amoco, deserve a higher relative valuation, as measured by price to earnings (P/E) ratios and other measures. Analyst commentaries suggest that this is due in part to the larger companies' ability to achieve higher rates of return on capital employed, which is commonly referred to as ROCE. Over time, we believe that the combined company will be able to generate higher ROCE than either company on a standalone basis, as a result of improved capital efficiency through funding the best growth opportunities of both companies. We believe that following the merger, ChevronTexaco will be able to generate merger synergies that will help ChevronTexaco to better compete with its competitors in earnings growth, ROCE, and total shareholder return. We believe the combined company will have the strength and resources to compete more effectively with our largest competitors and succeed around the globe. ChevronTexaco will have o world-class positions in reserves, production and exploration opportunities; o an integrated, worldwide refining and marketing business; o a global chemicals business (principally through Chevron Phillips Chemical Company, a recently formed joint venture with Phillips Petroleum Company); o expanded growth opportunities in natural gas and power; and o industry leading skills in technology innovation. We believe that the benefits of the merger will be realized in many different areas: o Significant cost savings: We believe that the combined company can operate more efficiently than can either individual company. Specifically, we expect that the merger will reduce our combined costs by at least $1.2 billion per year and that this reduction will be realized within six to nine months of the merger's completion. Based on integration planning efforts to date, we continue to expect that these cost savings will be realized. However, as discussed in the risk factors beginning on page 13, these -20-

cost savings are dependent, in part, on the timely and cost-effective integration of the two companies. We expect that the historic associations and strategic compatibility of Chevron and Texaco will enable rapid integration of the two companies. The most significant savings, approximately $700 million, will come from more efficient exploration and production activities, but other areas will contribute as well, including some $300 million from the consolidation of corporate functions and $200 million from other operations. We anticipate that the combined workforce of about 57,000 will be reduced by approximately seven percent worldwide. o Leadership position in exploration and production (or "Upstream"): We expect the combined company to be a premier global competitor in the exploration and production of petroleum and natural gas, with a significantly enhanced leadership position in most of the world's major and emerging exploration and producing areas. In addition, Chevron and Texaco have complementary positions in many promising geographical areas, as well as overlap and synergy in many of the mature and large exploration and production operations around the world. For example: o ChevronTexaco will have world-class reserves and growth opportunities in both west Africa and the Caspian region, where, in the latter case, the new company will be the largest producer. o The combined company will have a superior exploration acreage position in promising deepwater areas in West Africa, Brazil and the U.S. Gulf of Mexico. o The combination will significantly strengthen positions in core producing areas in North America and the North Sea. o The combination will create an outstanding portfolio of growth opportunities in Latin America and the Asia-Pacific region. o On a worldwide basis, the new company will hold the fourth largest oil and gas reserve position, with reserves of 11.5 billion barrels of oil equivalent, and will be the fourth largest producer, with a daily production of 2.7 million barrels. o In the United States, ChevronTexaco will be the nation's third largest producer of oil and gas, with production of 1.1 million barrels of oil equivalent per day, and will hold the nation's third largest reserve position, with 3.9 billion barrels of proved reserves. o Worldwide petroleum refining and marketing (or "downstream") platform: ChevronTexaco will create a worldwide business built around three well-recognized, international brands: Chevron, Texaco and Caltex. By integrating the operations of Caltex, a 65-year international refining and marketing joint venture between Chevron and Texaco, the combined company will be able to realize efficiencies from streamlined decision-making and management. The merger also allows the combined company to take a worldwide approach to lubricants (including the well-known quality lubricants brands Havoline and Delo), trading, international markets and customers, and to expand on the existing fuels and marine marketing joint venture. In addition, the brand presence of the combined company may help facilitate new activities and entries in other areas, including the upstream, and the gas and power businesses in Asia, Latin America and Europe. o Strength and scale in chemicals: The chemicals business of the combined company will mainly consist of Chevron's recently formed 50/50 joint venture, Chevron Phillips Chemical Company. With more than $6 billion in assets and $6 billion in annual revenues, Chevron Phillips Chemical Company has a strong, global position in three primary chemical products: olefins, polyolefins and aromatics. o Power generation: Texaco's power and gasification (the conversion of low-grade liquid petroleum products to useful gas products) business, with equity interests in 3,500 megawatts of power operating or under construction, and Chevron's 26 percent stake in Dynegy, Inc., give the combined company more options in the fast-growing power and energy convergence businesses. -21-

o Broad technology portfolio: The merger will strengthen the new company's technologies in its core businesses by bringing together specialized expertise from the two companies. The combined company will also have a broader portfolio in advanced technologies, e-business ventures and alternate energy, such as fuel cells and gas-to-liquids conversion. Chevron and Texaco are natural partners. We have a historic relationship with each other and the operational fit of our companies is highly complementary because we operate in many of the same areas in many of the same lines of business. We know each other well, and we already have long, highly productive experience working together in both the upstream and downstream, which we believe will permit a smooth integration of the companies. In addition, Chevron and Texaco share common corporate values. These values include protection of the environment, active support for the communities where we operate, and promoting diversity and opportunity in our workforce and among our business partners. Finally, we believe that ChevronTexaco will benefit from improved organizational capability. The capabilities of the new company will be strengthened by the combination of people from both Chevron and Texaco who have the diverse skills, talent and vast experience to compete successfully in an increasingly competitive industry. The merged company will also benefit from proven leadership in many facets of the global, integrated energy business and a track record of success in executing key strategies. Recommendation of, and Factors Considered by, the Chevron Board The Chevron board met on October 15, 2000 to consider and vote upon the merger and related transactions. At this meeting, after due consideration, the Chevron board: o determined that the merger and other transactions contemplated by the merger agreement, including the issuance of Chevron common stock in the merger and the stock option agreements, are fair to, and in the best interests of, Chevron and its stockholders; o approved the merger agreement, the option agreements, related documents and the transactions contemplated by those agreements and documents; o approved and declared advisable the amendment of Chevron's restated certificate of incorporation to change Chevron's name to "ChevronTexaco Corporation"; and o determined to recommend that the Chevron stockholders approve the issuance of Chevron common stock in the merger and the proposed name change amendment to the restated certificate of incorporation. Accordingly, the Chevron board recommends that Chevron stockholders vote for approval of (a) the proposed issuance of Chevron common stock in connection with the merger and (b) the amendment of Chevron's restated certificate of incorporation to change Chevron's name to "ChevronTexaco Corporation." In reaching these decisions and recommendations, the Chevron board considered and discussed the information provided to it at and prior to the October 15 meeting, including presentations by Chevron's management, as well as by Chevron's legal and financial advisors. The Chevron board considered the following material factors in the context of information concerning Chevron's and Texaco's respective businesses, financial performance and condition, operations, management, competitive position, and stock performance: o all of the reasons described under "Our Reasons for the Merger" beginning on page 19; o the exchange ratio being used in the merger and the resulting ownership interest of approximately 61.1 percent in ChevronTexaco by Chevron's current stockholders based upon the number of shares of Chevron and Texaco common stock outstanding on October 15, 2000; -22-

o the analyses and presentations of Lehman Brothers Inc. on the financial aspects of the merger, and their written opinion, delivered October 15, 2000, that, as of that date, the exchange ratio in the merger was fair, from a financial point of view, to Chevron; o the corporate governance arrangements for the combined company, including the fact that nine of the fifteen members of the board of directors of the combined company will be Chevron directors prior to the merger and the fact that David J. O'Reilly will be the Chairman and Chief Executive Officer of the combined company and that Richard A. Matzke will be a Vice Chairman of the combined company; o the fact that the headquarters of the combined company will be in San Francisco, California; o the long-time associations between Chevron and Texaco, and their knowledge of each other's business; o the risks and potential rewards associated with, as an alternative to the merger, continuing to execute Chevron's strategic plan as an independent entity. These risks include, among others, those associated with remaining independent amidst industry-wide consolidation, and the rewards include the ability of existing Chevron stockholders to share in the potential future growth and profits of Chevron; o the feasibility of potential business combinations or joint ventures with an entity other than Texaco and the conclusion that a transaction with Texaco is more feasible, and is expected to yield greater benefits, than the likely alternatives; o current industry, economic and market conditions, including the increased competitive position achieved by Exxon from its acquisition of Mobil and by BP from its acquisitions of Amoco and ARCO, and the higher trading multiples accorded to the equity of the "super-majors" in the securities markets (BP Amoco, ExxonMobil, and Royal Dutch/Shell), such as price-to-2001 estimated earnings multiples, as of October 13, 2000, of 17.0 for BP Amoco, 21.7 for ExxonMobil and 18.8 for Royal Dutch/Shell as compared to 13.7 for Chevron; o our expectation that the merger will be a "tax-free reorganization" for U.S. federal income tax purposes; o our expectation that the merger will be accounted for as a "pooling-of-interests," the potential restrictions on corporate activities as a condition and consequence of pooling, and the letter from PricewaterhouseCoopers LLP, as of October 15, 2000, concurring with Chevron's conclusion that as of that date, no conditions existed that would preclude accounting for the merger as a pooling-of-interests; o our expectation that the merger will yield significant cost savings, in part through an approximate 7% workforce reduction worldwide; o the implications and potential advantages and disadvantages of the "deal protection" provisions of the merger agreement, including "no solicitation" clauses, breakup fees, stock options and a restriction against terminating the agreement until it has been voted on by stockholders and that these provisions allow Chevron to furnish information to and conduct negotiations with third parties and also allow the Chevron board, upon receipt of a superior proposal, to change its recommendation to stockholders with respect to the merger; and o that the representations and warranties contained in the merger agreement are generally reciprocal and qualified by what does not result in a material adverse effect on either Chevron or Texaco. The Chevron board also considered the potential adverse consequences of other factors on the proposed merger, including: o the risk of a prolonged delay between the signing of the merger agreement and closing of the merger resulting from potential political and regulatory obstacles typically associated with an antitrust review of a significant transaction in the oil and gas sector; -23-

o the likelihood that some significant divestitures will be required and the risk that the circumstances of any such divestitures may not maximize the value received for the divested assets; o the existence of risks associated with unexpected difficulties in integrating the two companies, disappointments in the quality of the acquired assets or businesses, or material liabilities undetected in the due diligence process; o the risk of diverting management focus and corporate resources from other strategic opportunities and operational matters for an extended period of time; and o the fact that the deal protection provisions of the merger agreement could discourage alternative proposals being made for Chevron and could prevent an alternative business combination with Chevron from being accounted for as a pooling-of-interests (in this regard, the board took into account the likelihood of a proposal being made for Chevron, that the various provisions are not unusual for transactions of this type and that the termination fees were for amounts within a range that is customary). This discussion of the information and factors considered by the Chevron board is not intended to be exhaustive. In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the Chevron board did not quantify or otherwise assign relative weights to the specific factors it considered. In addition, the Chevron board did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to the board's ultimate determination or assign any particular weight to any factor, but rather the board conducted an overall analysis of the factors described above, including thorough discussions with and questioning of Chevron's management and legal, financial and accounting advisors. In considering the factors described above, individual members of the Chevron board may have given different weights to different information and different factors. The Chevron board considered this information and these factors as a whole, and overall considered the relevant information and factors to be favorable to, and in support of, its determinations and recommendations. Recommendation of, and Factors Considered by, the Texaco Board The Texaco board met on October 15, 2000 to consider and vote on the merger. At this meeting, after due consideration, the Texaco board: o determined that the merger and other transactions contemplated by the merger agreement and the stock option agreements are fair to and in the best interests of Texaco and its stockholders; o approved the merger agreement, the option agreements, and the transactions contemplated by those agreements; and o determined to recommend that the Texaco stockholders approve the merger agreement and the merger. Accordingly, the Texaco board recommends that Texaco stockholders vote for approval of the merger and the merger agreement. In reaching its decision to approve and recommend the merger, the Texaco board considered and discussed the information provided to it at and prior to the October 15 meeting, including presentations by Texaco's management, as well as by Texaco's legal and financial advisors. The Texaco board considered the following material factors in the context of information concerning Texaco's and Chevron's respective businesses, financial performance and condition, operations, management, competitive position and stock performance: o all of the reasons described under "Our Reasons for the Merger" beginning on page 19; o the risks associated with, as an alternative to the merger, continuing to execute Texaco's strategic plan as an independent entity. The risks included, among others: -24-

o remaining independent amidst industry-wide consolidation; o that the relative size, scale and scope of the operations of oil and gas companies appeared to be making an increasing difference in price/cash flow and price/earnings ratios, as well as to analysts and investors; o that historically low upstream prices might reoccur over the strategic plan's period, which would make it difficult to reach plan objectives; and o that a delay in any of the company's upstream projects would likely materially impact reaching plan objectives; o the board's conclusion that the merger will result in a combined company with the expanded scale, scope and growth opportunities necessary to compete in the changed competitive landscape; o the fact that since late 1998 Texaco had seriously considered an acquisition of, or business combination with, several other parties. Of these, three (including Chevron) would have resulted in formation of a mega-major, one would have involved acquisition of an independent upstream company and two would have resulted in a sizeable expansion into the gas/power sectors. Discussions were held with each of these potential partners, but no transaction resulted with any party except Chevron; o current industry, economic and market conditions, including the increased competitive position achieved by Exxon from its acquisition of Mobil and by BP from its acquisitions of Amoco and ARCO, and the higher trading multiples accorded to the equity of the "super-majors" in the securities markets, such as price-to-2001 estimated earnings multiples, as of October 13, 2000, of 15.3 for BP Amoco, 19.2 for Exxon Mobil and 19.4 for Royal Dutch/Shell as compared to 12.4 for Texaco, and price-to-2001 estimated cash flow multiples, as of October 13, 2000, of 9.9 for BP Amoco, 12.3 for Exxon Mobil and 11.9 for Royal Dutch/Shell as compared to 6.8 for Texaco; o that the 0.77 exchange ratio provided for in the merger agreement represented a 17.7 percent premium to the closing Texaco stock price on October 13, 2000, a 25.3 percent premium to the average Texaco stock price over the 30 days prior to the signing of the merger agreement, and premiums ranging from 14.6 percent to 25.9 percent to the average Texaco stock price over other periods ranging from one week to three years; o that Chevron had proposed an exchange ratio of 0.765 in 1999; o that the premiums paid in comparable transactions reviewed by the board, based on the last closing share price of the applicable companies before the announcement or rumor of a transaction, ranged from 23 percent to 33 percent; o the resulting approximate 38.9 percent ownership interest in ChevronTexaco by Texaco's current stockholders; o the analyses and presentations of Credit Suisse First Boston on the financial aspects of the merger, including the fact that the 0.77 exchange ratio was above or at the upper end of each exchange ratio reference range implied by each financial analysis that Credit Suisse First Boston presented, and Credit Suisse First Boston's written opinion, delivered October 15, 2000, that, as of that date, the exchange ratio was fair from a financial point of view to the holders of Texaco common stock; o the corporate governance arrangements for the combined company, including that six Texaco designees will become directors of the combined company; o our expectation that the merger will be a "tax-free reorganization" for U.S. federal income tax purposes; o our expectation that the merger will be accounted for as a "pooling-of-interests," the potential restrictions on corporate activities as a condition and consequence of pooling, and the opinion of Arthur Andersen LLP, as of October 15, 2000, to the effect that Texaco is eligible to participate in a transaction accounted for as a pooling-of-interests; -25-

o the potential effect of the "deal protection" provisions on possible third party proposals to acquire Texaco after execution of the merger agreement, including that if any third party made a superior proposal, the Texaco board could provide information to and engage in negotiations with that third party and decide not to recommend the merger, but that the Texaco Board could not terminate the merger agreement until it had been voted on by stockholders; o that while the termination payment provisions of the merger agreement could have the effect of discouraging alternative proposals for a business combination with Texaco and that the stock option agreement could prevent an alternative business combination with Texaco from being accounted for as a pooling-of-interests, these provisions would not preclude bona fide alternative proposals, and that the size of the termination fee was reasonable in light of the size and benefits of the transaction; o the ability of Texaco generally to conduct its business in the ordinary course pending closing under the terms of the merger agreement; o the representations and warranties contained in the merger agreement are generally reciprocal and qualified by an exception for matters that would not result in a material adverse effect on either Chevron or Texaco; and o the long-time associations between Chevron and Texaco, and their knowledge of each other's business. The Texaco board also considered the potential adverse consequences of other factors on the proposed merger, including: o while the exchange ratio provided for in the merger agreement is approximately the same as the exchange ratio proposed by Chevron in 1999, the dollar value of the merger consideration is somewhat less than the dollar value implied by the exchange ratio proposed in 1999, as explained below. Notwithstanding this difference in value, the board concluded that the merger was in the best interests of Texaco's stockholders for the reasons stated above, especially the recognition that industry consolidation made it important to increase in size to sustain growth in stockholder value. o based on Chevron's closing share price of $90.4375 on June 1, 1999 (the last trading day before the Texaco board considered Chevron's 1999 offer), the dollar value of the consideration implied by the proposed ratio would have been $69.18 per share of Texaco stock. Based on Chevron's closing share price of $84.25 on October 13, 2000 (the last trading day before the signing of the merger agreement), the dollar value of consideration implied by the ratio provided for in the merger agreement is $64.87. In either case, the consideration actually to be received by the stockholders will be determined by the Chevron share price on the merger date; o the risk of a prolonged delay between the signing of the merger agreement and closing of the merger resulting from potential political and regulatory obstacles typically associated with an antitrust review of a significant transaction in the oil and gas sector; o the likelihood that some significant divestitures will be required and the risk that the circumstances of any such divestitures may not maximize the value received for the divested assets; o the existence of risks associated with unexpected difficulties in integrating the two companies, disappointments in the quality of Chevron's assets or businesses, or material liabilities undetected in the due diligence process; o the risk of diverting management focus and corporate resources from other strategic opportunities and operational matters for an extended period of time; and o the interests that executive officers and directors of Texaco may have with respect to the merger in addition to their interests as stockholders of Texaco generally, as described more fully in "Interests of Directors and Officers in the Merger" on page 47. This discussion of the information and factors considered by the Texaco board is not intended to be exhaustive. In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the Texaco board did not quantify or otherwise assign relative weights to the specific -26-

factors it considered. Individual members of the Texaco board may have given different weights to different information and different factors. The Texaco board considered this information and these factors as a whole, and overall considered the relevant information and factors to be favorable to, and in support of, its determinations and recommendations. Directors of ChevronTexaco Upon completion of the merger, the board of directors of ChevronTexaco will be comprised of fifteen individuals, nine of whom will be directors of Chevron prior to the merger and six of whom will be directors of Texaco prior to the merger designated by Texaco. At least one Texaco designee will be appointed to each committee of the board of directors of ChevronTexaco. Principal Officers of ChevronTexaco David J. O'Reilly will be the Chairman and Chief Executive Officer of ChevronTexaco. Richard H. Matzke and Glenn F. Tilton will be Vice Chairmen. Messrs. O'Reilly, Matzke and Tilton will form a newly created Office of the Chairman, which will have oversight of the operations of ChevronTexaco. Other Executive Officers of ChevronTexaco Darry W. Callahan, currently Executive Vice President of Chevron, will retain his responsibilities for technology, chemical additives and coal, plus power and gasification as Executive Vice President, Power, Chemicals and Technology of ChevronTexaco. Mr. Callahan will also have responsibility for ChevronTexaco's interests in the Chevron Phillips Chemical Company joint venture, Dynegy, Inc., and the Sasol/Chevron Gas-to-Liquids joint venture; Harvey D. Hinman, Esq., currently Vice President and General Counsel of Chevron, will be Vice President and General Counsel of ChevronTexaco; George Kirkland, currently Vice President of Chevron and President of Chevron U.S.A. Production Company, will be Vice President and President, North America, of ChevronTexaco; Peter J. Robertson, currently Vice President of Chevron and President of Chevron Overseas Petroleum, will be Vice President and President, Overseas Petroleum, of ChevronTexaco; John S. Watson, currently Vice President, Finance and Chief Financial Office of Chevron, will be Vice President, Finance and Chief Financial Officer of ChevronTexaco; and Patricia A. Woertz, currently Vice President of Chevron, and President, Chevron Products Company, will lead ChevronTexaco's global downstream businesses as Executive Vice President, Downstream, of ChevronTexaco. Accounting Treatment We expect that the merger will be accounted for under the "pooling-of-interests" method under the requirements of Opinion No. 16 (Business Combinations) of the Accounting Principles Board of the American Institute of Certified Public Accountants, the Financial Accounting Standards Board, and the rules and regulations of the SEC. Chevron has received a letter regarding pooling dated October 15, 2000 from PricewaterhouseCoopers LLP, its independent accountants. The letter states that, as of October 15, 2000, based on information provided to PricewaterhouseCoopers LLP by Chevron and based on the Arthur Andersen LLP letter described below, PricewaterhouseCoopers LLP concurred with Chevron's conclusion that no conditions existed which would preclude Chevron from accounting for the merger as a pooling-of-interests. -27-

Texaco has received a letter regarding pooling dated October 15, 2000 from Arthur Andersen LLP, its independent accounting firm. The letter states that, as of October 15, 2000, Arthur Andersen LLP concurred with Texaco's conclusion that Texaco is eligible to participate in a transaction to be accounted for as a pooling-of-interests. The receipt of letters from PricewaterhouseCoopers LLP and Arthur Andersen LLP dated as of the closing date of the merger reconfirming their conclusions is a condition to the closing of the merger. Under the pooling-of-interests accounting method, the reported balance sheet amounts and results of operations of the separate companies for prior periods will be combined, reclassified and conformed, as appropriate, to reflect the combined financial position and results of operations for ChevronTexaco. See "Unaudited Pro Forma Condensed Combined Financial Statements" beginning on page 55. Material Federal Income Tax Consequences of the Merger The following discussion summarizes the opinions of McDermott, Will & Emery, tax counsel to Chevron, and Davis Polk & Wardwell, tax counsel to Texaco (together, "tax counsel"), dated as of the date of this joint proxy statement/prospectus, as to the material federal income tax consequences of the merger. We have filed these opinions with the SEC as exhibits to the registration statement related to this joint proxy statement/prospectus. See "Where You Can Find More Information" on page 85. It is a condition to the obligations of Texaco and Chevron to complete the merger that on the closing date each receive an additional legal opinion (the "closing date opinions") from its tax counsel that the merger constitutes a tax-free reorganization, within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended, for federal income tax purposes. Although the merger agreement allows us to waive this condition to closing, Chevron and Texaco currently do not anticipate doing so. If either of us does waive the condition that closing date opinions be received, we will resolicit proxies and ask you to vote on the merger taking this and all risks resulting to the stockholders from such a waiver into consideration. In delivering their opinions regarding the merger as of the date of this joint proxy statement/prospectus, tax counsel have each relied, and in delivering the closing date opinions, tax counsel will each rely, on o representations and covenants made by Chevron and Texaco, including those contained in certificates of officers of Chevron and Texaco, and o specified assumptions, including an assumption regarding the completion of the merger in the manner contemplated by the merger agreement. In addition, in their opinions dated as of the date of this joint proxy statement/prospectus, tax counsel have assumed, and tax counsel's ability to provide the closing date opinions will depend on, the absence of changes in existing facts or in law between the date of this joint proxy statement/prospectus and the closing date. If any of those representations, covenants or assumptions is inaccurate or if any such change in fact or law occurs, then either or both tax counsel may not be able to provide the required closing date opinions and the tax consequences of the merger could differ from those described in the opinions that tax counsel have delivered. The Internal Revenue Service may not adopt tax counsel's opinions and may adopt a contrary position, which may be sustained by the courts. Neither Texaco nor Chevron intends to obtain a ruling from the Internal Revenue Service with respect to the tax consequences of the merger. Based on the assumptions, representations and covenants described above, it is the opinion of each tax counsel that the merger will qualify as a reorganization under Section 368(a) of the Internal Revenue Code. The discussion below assumes that the merger is treated in accordance with the opinions just described and is based upon the Internal Revenue Code, the regulations promulgated under the Internal Revenue Code, Internal Revenue Service rulings, and judicial and administrative rulings in effect as of the date hereof, all of which are subject to change, possibly with retroactive effect. The discussion below does not address all aspects of federal income taxation that may be relevant to a stockholder in light of the stockholder's particular circumstances or to those Texaco stockholders subject to special rules, such as stockholders who are not citizens or residents of the United States, stockholders that are foreign corporations, foreign estates or foreign trusts, financial institutions, tax-exempt organizations, insurance companies, dealers or brokers in securities, stockholders who acquired their Texaco stock -28-

upon the exercise of options or similar derivative securities or otherwise as compensation or stockholders who hold their Texaco stock as part of a hedge, appreciated financial position, straddle or conversion transaction. This discussion assumes that Texaco stockholders hold their respective shares of Texaco stock as capital assets within the meaning of Section 1221 of the Internal Revenue Code. Federal Income Tax Consequences to Chevron Stockholders. Holders of Chevron stock will not recognize any gain or loss for federal income tax purposes as a result of the merger. Federal Income Tax Consequences to Texaco Stockholders. Holders of shares of Texaco stock will (1) not recognize any gain or loss for federal income tax purposes as a result of the exchange of their shares of Texaco stock for ChevronTexaco common stock in the merger except with respect to cash received instead of a fractional share of ChevronTexaco common stock and (2) have a tax basis in the ChevronTexaco common stock received in the merger equal to the tax basis of the Texaco stock surrendered in the merger less any tax basis of the Texaco stock surrendered that is allocable to a fractional share of ChevronTexaco common stock for which cash is received. The Texaco stockholders' holding period with respect to the ChevronTexaco common stock received in the merger will include the holding period of the Texaco stock surrendered in the merger. To the extent that a holder of shares of Texaco stock receives cash instead of a fractional share of ChevronTexaco common stock, the holder will be required to recognize gain or loss for federal income tax purposes, measured by the difference between the amount of cash received and the portion of the tax basis of the holder's shares of Texaco stock allocable to such fractional share of ChevronTexaco common stock. This gain or loss will be a capital gain or loss and will be a long-term capital gain or loss if the share of Texaco stock exchanged for the fractional share of ChevronTexaco common stock was held continuously for more than one year at the effective time of the merger. Federal Income Tax Consequences to Texaco, Chevron and the Merger Subsidiary. None of Chevron, Texaco, or the merger subsidiary will recognize gain or loss for federal income tax purposes as a result of the merger. We intend this discussion to provide only a summary of the material federal income tax consequences of the merger. We do not intend that it be a complete analysis or description of all potential federal income tax consequences of the merger. In addition, we do not address tax consequences that may vary with, or are contingent upon, a stockholder's particular circumstances. Moreover, we do not address any non-income tax or any foreign, state or local tax consequences of the merger. Accordingly, we strongly urge you to consult your tax advisor to determine your United States federal, state, local or foreign income or other tax consequences resulting from the merger, with respect to your individual circumstances. Regulatory Matters U.S. Antitrust. Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the related rules, the merger may not be completed until notifications have been given, information requested by the FTC has been furnished to it and waiting period requirements have been satisfied. Chevron and Texaco submitted these notifications on October 23 and October 24, 2000, respectively. On October 25, 2000, we received an informal request for additional information from the FTC, and commenced developing responsive information and submitting it to the FTC on a voluntary basis. On November 17, 2000, Chevron voluntarily re-submitted its filing in order to provide the staff of the FTC additional time to consider the information voluntarily provided by Chevron and Texaco in advance of the staff's formulating a formal second request for information. Chevron and Texaco received additional informal requests for information on December 1, 2000. On December 15, 2000, the staff of the FTC issued a formal second request for information. We are in the process of responding to this request. If the FTC believes that the merger would violate the federal antitrust law by substantially lessening competition in any line of commerce affecting U.S. consumers, the FTC has the authority to challenge the merger by seeking a federal court order temporarily enjoining the transaction pending conclusion of an administrative hearing. The FTC may also proceed with an administrative proceeding if the injunction is denied, and if the merger is found to be anticompetitive, challenge it after the fact. We can give no assurance that a challenge to the merger will not be made or, if such a challenge is made, that it would be unsuccessful. In addition, a number of state attorneys general -29-

have indicated their intent to review the proposed merger and to coordinate that review with the FTC. Expiration or termination of the HSR Act waiting period is a condition to the merger. See "The Merger Agreement--Conditions to the Completion of the Merger" on page 70. We anticipate that the FTC will require asset dispositions as a condition of not challenging the merger. While the scope and method of such dispositions are unknown at this time, we do anticipate being required to make divestitures of United States refining, marketing and transportation businesses in order to address market concentration concerns. We believe that we will be able to resolve these concerns by the disposition of Texaco's interests in Equilon and Motiva. European Union. On March 1, 2001, the European Union announced that it had approved the merger. Other Laws. Chevron and Texaco conduct operations in a number of jurisdictions where other regulatory filings or approvals are required or advisable in connection with the completion of the merger. We have made filings in some jurisdictions and are currently in the process of reviewing whether other filings or approvals may be required or desirable in other jurisdictions. We recognize that some of these filings may not be completed before the closing, and that some of these approvals, which are not as a matter of practice required to be obtained prior to effectiveness of a merger transaction, may not be obtained prior to the closing. General. It is possible that governmental entities having jurisdiction over Chevron and Texaco may seek regulatory concessions as conditions for granting approval of the merger. If any regulatory body's approval contains terms which would be reasonably likely to result in a material adverse effect on ChevronTexaco after the closing, Chevron or Texaco can decline to close under the merger agreement. We can give no assurance that the required regulatory approvals will be obtained on terms that satisfy the conditions to closing of the merger or within the time frame contemplated by Chevron and Texaco. See "The Merger Agreement--Conditions to the Completion of the Merger" on page 70. Appraisal Rights Holders of Chevron common stock and Texaco common stock are not entitled to appraisal rights under Delaware law in connection with the merger. Appraisal rights under Delaware law are not available in connection with the merger because the shares of ChevronTexaco common stock that Texaco stockholders will be entitled to receive in the merger will be listed on the New York Stock Exchange at the closing and because Texaco common stock was traded on the New York Stock Exchange as of the record date. Federal Securities Laws Consequences; Stock Transfer Restriction Agreements This joint proxy statement/prospectus does not cover any resales of the ChevronTexaco common stock to be received by the stockholders of Texaco upon completion of the merger, and no person is authorized to make any use of this joint proxy statement/prospectus in connection with any such resale. All shares of ChevronTexaco common stock received by Texaco stockholders in the merger will be freely transferable, except that shares of ChevronTexaco common stock received by persons who are deemed to be "affiliates" of Texaco under the Securities Act of 1933, as amended, at the time of the Texaco meeting may be resold by them only in transactions permitted by Rule 145 under the 1933 Act or as otherwise permitted under the 1933 Act. Persons who may be deemed to be affiliates of Texaco for such purposes generally include individuals or entities that control, are controlled by or are under common control with Texaco and include directors and some of the executive officers of Texaco. The merger agreement requires Texaco to use its reasonable best efforts to cause each of such affiliates to execute a written agreement to the effect that such persons will not sell, transfer or otherwise dispose of any of the shares of ChevronTexaco common stock issued to them in the merger in violation of the 1933 Act or the related SEC rules. In addition, each of the directors and some of the executive officers of Chevron and Texaco are expected to execute written agreements prohibiting them from selling, transferring or otherwise disposing of, or acquiring or selling any options or other securities relating to, securities of Chevron or Texaco that would be intended to reduce -30-

the individual's risk relative to, any shares of Chevron common stock or Texaco common stock beneficially owned by him or her during the period, beginning 30 days prior to the closing and ending at such time as financial results covering at least 30 days of combined operations of Chevron and Texaco have been publicly released by ChevronTexaco after the merger. -31-

OPINIONS OF FINANCIAL ADVISORS We each retained our own financial advisor to assist us and our boards of directors in the consideration of valuation, financial and other matters relating to the merger. Chevron retained Lehman Brothers Inc. as its financial advisor and Texaco retained Credit Suisse First Boston Corporation as its financial advisor. Opinion of Chevron's Financial Advisor General. Lehman Brothers has acted as financial advisor to Chevron in connection with the merger. On October 15, 2000, Lehman Brothers rendered its opinion to the Chevron board of directors that as of such date, from a financial point of view, the exchange ratio to be paid by Chevron to Texaco stockholders in the merger was fair to Chevron. The full text of the Lehman Brothers opinion dated October 15, 2000 is included as Appendix D to this joint proxy statement/prospectus. Holders of Chevron common stock may read the Lehman Brothers opinion for a discussion of the factors considered, assumptions made and qualifications of the review undertaken by Lehman Brothers in connection with its opinion. Lehman Brothers' advisory services and opinion were provided for the information and assistance of the Chevron board of directors in connection with its consideration of the merger. Lehman Brothers' opinion is not a recommendation to any stockholder of Chevron as to how such stockholder should vote with respect to the merger. Lehman Brothers was not requested to opine as to, and its opinion does not address, Chevron's underlying business decision to proceed with or effect the merger. In arriving at its opinion, Lehman Brothers reviewed, among other things: o the merger agreement and specific terms of the merger; o publicly available information concerning Chevron and Texaco that Lehman Brothers believed to be relevant to its analysis, including Annual Reports on Form 10-K for the fiscal year ended December 31, 1999 and Quarterly Reports on Form 10-Q for the quarters ended March 31 and June 30, 2000; o financial and operating information with respect to the business, operations and prospects of Chevron furnished to Lehman Brothers by Chevron, including the amounts and timing of the cost savings and operating synergies which management of Chevron estimates will result from a combination of the businesses of Chevron and Texaco; o the trading histories of Chevron's common stock and Texaco's common stock from September 22, 1999 to October 13, 2000 and a comparison of these trading histories with each other and with those of other companies that Lehman Brothers deemed relevant; o a comparison of the historical financial results and present financial condition of each of Chevron and Texaco with each other and with those of other companies that Lehman Brothers deemed relevant; o a comparison of the financial terms of the merger with the financial terms of a number of other transactions that Lehman Brothers deemed relevant; o the potential pro forma impact of the merger on the future financial performance of Chevron (including the expected cost savings and synergies); o the relative contributions of Chevron and Texaco to the historical and future financial performance of the combined company on a pro forma basis; and o the pro forma impact on the combined company of the potential divestiture of Texaco's two domestic downstream businesses in connection with the merger. -32-

In addition, Lehman Brothers had discussions with the managements of Texaco and Chevron concerning their respective businesses, operations, assets, financial conditions and prospects and undertook such other studies, analyses and investigations as Lehman Brothers deemed appropriate. In arriving at its opinion, Lehman Brothers assumed and relied upon the accuracy and completeness of the financial and other information used by it without assuming any responsibility for independent verification of such information. With respect to information regarding Chevron, Lehman Brothers relied upon the assurances of the management of Chevron that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. In arriving at its opinion, Lehman Brothers did not rely upon financial forecasts or business plans of Chevron and Texaco prepared by management of Chevron or Texaco. Accordingly, with the consent of Chevron, Lehman Brothers assumed that the published estimates of third-party research analysts were a reasonable basis upon which to evaluate the future financial performance of Chevron and Texaco and that Chevron and Texaco would perform substantially in accordance with such estimates. Upon the advice of Chevron, Lehman Brothers also assumed that the amounts and timing of the expected cost savings and operating synergies were reasonable and that the cost savings would be realized substantially in accordance with such estimates. In arriving at its opinion, Lehman Brothers did not conduct a physical inspection of the properties and facilities of Chevron or Texaco. Lehman Brothers also did not make or obtain any evaluations or appraisals of the assets or liabilities of Chevron or Texaco. Upon advice of Chevron, Lehman Brothers assumed that the merger will qualify (a) for pooling-of-interests accounting treatment and (b) as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and therefore as a tax-free transaction to the stockholders of Texaco. Lehman Brothers' opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, October 15, 2000. In arriving at its opinion, Lehman Brothers did not ascribe a specific range of value to Chevron or Texaco, but rather made its determination as to the fairness to Chevron, from a financial point of view, of the exchange ratio to be offered to Texaco's stockholders in the merger on the basis of financial and comparative analyses described below. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial and comparative analysis and the application of those methods to the particular circumstances, and therefore, such an opinion is not readily susceptible to summary description. Furthermore, Lehman Brothers did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. In particular, with regard to the comparable company and comparable transaction analyses summarized below, because of the inherent differences between the businesses, operations, financial conditions and prospects of Chevron and Texaco and the businesses, operations, financial conditions and prospects of the companies included in their comparable company group and in the comparable transaction group, Lehman Brothers believed that it was inappropriate to rely solely on the quantitative results of the analysis. Accordingly, Lehman Brothers also made qualitative judgments concerning differences between the financial and operating characteristics of Chevron, Texaco and the companies in their respective comparable company groups and in the comparable transaction analysis that would affect the public trading values of Chevron, Texaco and the comparable companies. These judgments, based on Lehman Brothers' own experience, involve complex considerations of general economic, market and financial conditions as well as considerations of the business, operations and market positions of some or all of the companies in the comparable companies group and comparable transactions group. Because these judgments and considerations vary from company to company, Lehman Brothers did not discuss with the board of directors of Chevron each qualitative judgment or consideration made with respect to each of the companies included in the comparable companies group and comparable transactions group. Accordingly, Lehman Brothers believes that its analyses must be considered as a whole and that considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion. In its analyses, Lehman Brothers made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of Chevron and Texaco. None of Chevron, Texaco, Lehman Brothers or any other person assumes responsibility if future results are materially different from those discussed. Any estimates contained in these analyses were not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth in the analyses. In addition, analyses relating to the value of businesses do not purport to be appraisals or to reflect the prices at which businesses actually may be sold. -33-

The following is a summary of the material financial analyses prepared and used by Lehman Brothers in connection with rendering its opinion to the Chevron board of directors. Some of the summaries of the financial and comparative analyses include information presented in tabular format. In order to fully understand the methodologies used by Lehman Brothers and the results of its financial and comparative analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial and comparative analyses. Accordingly, the information presented in the tables and described below must be considered as a whole. Considering any portion of such analyses and of the factors considered, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying Lehman Brothers' opinion. Valuation Analysis Lehman Brothers performed a valuation analysis of Chevron and Texaco using the following methodologies: comparable company trading analysis; comparable transaction analysis; discounted cash flow analysis; and segment valuation analysis. Each of these methodologies was used to generate a reference enterprise value range for Chevron and Texaco. The enterprise value ranges were adjusted for relevant on and off balance sheet assets and liabilities to arrive at an equity value range (in aggregate dollars and dollars per share). The per share equity value ranges were then used to determine implied exchange ratio ranges. Summary descriptions of each of the valuation methodologies noted above and the implied exchange ratio ranges derived using each methodology are included in the following table. This table should be read together with the more detailed descriptions set forth below. Considering the exchange ratios without considering the narrative description of the financial analyses, including the assumptions underlying these analyses, could create a misleading or incomplete view of the process underlying, and conclusions represented by, Lehman Brothers' opinion. Summary Description of Valuation Valuation Methodology Methodology Implied Exchange Ratio - ----------------------------------- ------------------------------------------ --------------------------- Comparable Company Trading Analysis Market valuation benchmark based on the 0.71 -- 0.75 common stock trading multiples of selected comparable companies Comparable Transaction Analysis Market valuation benchmark based on the 0.72 -- 0.78 consideration paid in selected comparable precedent transactions Discounted Cash Flow Analysis Net present valuation of after-tax cash 0.71 -- 0.73 flows (based on third-party research analyst projections) using various discount rates and terminal value multiples and selected hydrocarbon pricing scenarios Segment Valuation Analysis Build up of total enterprise value based on 0.74 -- 0.80 the separate valuation of each of the business segments of the two companies; those separate segment valuations are based on the three methodologies highlighted above (comparable company trading analysis, comparable transaction analysis, and discounted cash flow analysis) - ----------------------------------------------------------------------------------------------------------------------- Implied Range 0.71 -- 0.80 - ----------------------------------------------------------------------------------------------------------------------- The Exchange Ratio in the Merger 0.77 - ----------------------------------------------------------------------------------------------------------------------- In conducting each of the analyses detailed in the above table, Lehman Brothers performed the same type of analysis with respect to both Chevron and Texaco. No additional premium was added to the Texaco valuations in -34-

any analysis to reflect the fact that Chevron is acquiring control of Texaco in the merger and that Chevron could thus expect to pay a control premium to Texaco stockholders. Lehman Brothers noted that some of the valuations supported the exchange ratio without incorporation of such a control premium. Lehman Brothers took into consideration that by incorporating a control premium into the Texaco valuations, the resulting implied exchange ratios, in Lehman Brothers' judgment, supported its opinion regarding the fairness, from a financial point of view, of the exchange ratio to Chevron. Comparable Company Trading Analysis. With respect to each of Chevron and Texaco, using publicly available information, Lehman Brothers compared selected financial data of each company with similar data of selected large-capitalization domestic and international integrated oil and gas companies. For each of these companies, Lehman Brothers calculated and analyzed the common equity market value multiples of various projected financial criteria based upon published analyst estimates of net income and discretionary cash flow for the years 2000 and 2001. Lehman Brothers also calculated and analyzed the ratio of enterprise value to earnings before interest, taxes, depreciation, amortization and exploration expense, commonly referred to as EBITDAX for the years 2000 and 2001. The enterprise value of each company was obtained by adding long-term debt to the sum of the market value of its common equity, the value of its preferred stock, and the book value of any minority interest minus the cash balance. The companies and their multiples of common equity market value to net income, or p/e ratio, based on consensus earnings estimates for the years 2000 and 2001, are detailed in the following table: 2000E 2001E Company P/E Ratio P/E Ratio ------------------------------------------------------ ------------- ------------ Exxon Mobil Corporation 20.6x 21.7x Royal Dutch Petroleum Company/The Shell Transport and Trading Company, p.l.c. 17.7x 18.8x TOTAL Fina Elf S.A. 17.3x 16.4x BP Amoco p.l.c. 15.2x 17.0x Chevron Corporation 12.1x 13.7x Texaco Inc. 11.5x 13.2x Eni S.p.A. 9.8x 10.7x Conoco Inc. 9.8x 10.7x Phillips Petroleum Company 9.5x 10.5x Repsol YPF, S.A. 9.4x 9.5x USX Corporation-Marathon Group 7.6x 9.1x Amerada Hess Corporation 7.0x 9.0x Occidental Petroleum Corporation 5.8x 6.9x This methodology yielded an implied exchange ratio range of 0.71 - 0.75. Comparable Transaction Analysis. Lehman Brothers reviewed publicly available information related to the following selected recent corporate merger transactions involving large-capitalization integrated oil and gas companies: Transaction Announcement Date - ------------------------------------------------------ ----------------------- The British Petroleum Company p.l.c./Amoco Corporation 8/11/98 Exxon Corporation/Mobil Corporation 12/1/98 TOTAL S.A./PetroFina S.A. 12/1/98 BP Amoco p.l.c./Atlantic Richfield Company 4/1/99 TOTAL Fina S.A./Elf Aquitaine S.A. 7/6/99 For each transaction, Lehman Brothers calculated equity and enterprise value multiples based on net income, discretionary cash flow and EBITDAX. This methodology yielded an implied exchange ratio range of 0.72 - 0.78. -35-

Discounted Cash Flow Analysis. Lehman Brothers prepared after-tax discounted cash flow models for both Chevron and Texaco utilizing third-party research analyst projections. Discount rates of 8 percent - 10 percent and terminal value EBITDAX multiples of 8.0x to 9.0x were used to generate a range of enterprise values, equity values and equity values per share for each of Chevron and Texaco. This methodology yielded an implied exchange ratio of 0.71 - 0.73. However, because of the subjectivity inherent in the assignment of discount rates to projected cash flows and multiples to derive terminal values, Lehman Brothers believed that it was inappropriate to and therefore did not, rely solely on the quantitative results of the discounted cash flow analysis. Segment Valuation Analysis. Lehman Brothers performed a comparable company trading analysis, a comparable transactions analysis and a discounted cash flow analysis for each of the business segments of Chevron and Texaco. Lehman Brothers segmented Chevron and Texaco along the operating segment categories that appear in each of Chevron and Texaco's respective Forms 10-K for the fiscal year ended December 31, 1999. For each segment, a different group of comparable companies and comparable transactions was examined. In addition, different discount rates and terminal multiples were used in the discounted cash flow analysis. The segment enterprise value ranges calculated were added together to calculate an enterprise value range for each of Chevron and Texaco. The segment valuation analysis resulted in an implied exchange ratio range of 0.74 - 0.80. Comparative Transaction Multiples Analysis Based on the exchange ratio and Chevron's closing stock price as of October 13, 2000, Lehman Brothers calculated an aggregate equity purchase price and an aggregate transaction enterprise value for the merger. Lehman Brothers calculated equity and enterprise value multiples for the merger based on different statistics of Texaco, including EBITDAX, discretionary cash flow and net income. Multiples were based on those statistics for 1999, 1997-1999 average and 1995-1999 average. Next, these transaction multiples were compared to the same multiples as calculated for the following three precedent transactions: o The British Petroleum Company p.l.c. / Amoco Corporation o Exxon Corporation / Mobil Corporation o BP Amoco p.l.c. / Atlantic Richfield Company Lehman Brothers determined that the transaction multiples implied by the exchange ratio in the merger were generally consistent with multiples of the three above-referenced precedent transactions. The following table sets forth the results of this analysis: Chevron/ Texaco Precedent Enterprise Value to: Multiple Transactions Average ------------------------------ ------------------ ---------------------- EBITDAX LTM 7.2x 11.0x 3-Year Average 10.0x 8.9x 5-Year Average 9.8x 9.5x Equity Purchase Price to: ------------------------------ Net Income LTM 17.1x 33.6x 3-Year Average 26.4x 22.4x 5-Year Average 25.9x 25.2x Discretionary Cash Flow LTM 8.5x 11.6x 3-Year Average 10.4x 10.9x 5-Year Average 10.5x 11.5x -36-

Contribution Analysis Lehman Brothers utilized publicly available historical financial data regarding Chevron and Texaco to calculate the relative contributions by Chevron and Texaco to the pro forma combined company with respect to net income and discretionary cash flow for the calendar years 1997, 1998 and 1999. Lehman Brothers also calculated similar contributions based on 2000 and 2001 projected net income and discretionary cash flow based on consensus earnings estimates for both companies as reported by First Call, a service reporting equity analyst estimates. In its analysis, Lehman Brothers did not consider the pro forma impact of any anticipated operating or cost saving synergies associated with the merger. In all cases, Lehman Brothers compared Chevron's contribution percentages to Chevron stockholders' expected 61 percent pro forma ownership of the combined company. The following table summarizes the results of this analysis. Chevron Texaco Implied Contribution Contribution Exchange Ratio ---------------- -------------- ----------------- Historical Results 1997 Net Income 62.7% 37.3% .716 1998 Net Income 68.5% 31.5% .553 1999 Net Income 64.6% 35.4% .660 1997 Discretionary Cash Flow 59.6% 40.4% .815 1998 Discretionary Cash Flow 63.5% 36.5% .691 1999 Discretionary Cash Flow 63.4% 36.6% .693 Projected Results 2000E Net Income 63.6% 36.4% .687 2001E Net Income 64.0% 36.0% .678 2000E Discretionary Cash Flow 63.0% 37.0% .707 2001E Discretionary Cash Flow 62.1% 37.9% .734 Premiums Paid Analysis Using publicly available information, Lehman Brothers reviewed the premiums paid in the following five precedent transactions: o The British Petroleum Company p.l.c. / Amoco Corporation o Exxon Corporation / Mobil Corporation o BP Amoco p.l.c. / Atlantic Richfield Company o TOTAL S.A. / PetroFina S.A. o TOTAL Fina S.A. / Elf Aquitaine S.A. For each of these five precedent transactions, Lehman Brothers calculated the premium per share paid by the acquiror by comparing the announced exchange ratio in each transaction to the historical exchange ratio implied by the relative trading performance of both the acquiror company's common stock and the target company's common stock during selected periods leading up the announcement date of the transaction. In two of the five transactions, market rumors of the transaction preceded actual announcement. In these cases, Lehman Brothers measured the premium relative to the two companies' closing prices as of the day before the "rumor surface date," which is a date prior to the date of official announcement when the acquiring company publicly confirmed the existence of discussions with the target company regarding a possible transaction. The two transactions where rumors existed are: -37-

Rumor Surface Announcement Transaction Date Date - ------------------------------------------ ------------- ------------ Exxon Corporation/Mobil Corporation 11/25/98 12/1/98 BP Amoco p.l.c./Atlantic Richfield Company 3/29/99 4/1/99 Lehman Brothers compared the premiums paid in the five precedent transactions to the premium being paid by Chevron to Texaco stockholders as calculated based on the two companies' relative stock price performance for various periods ending October 13, 2000. The table below sets forth the summary results of the analysis: Five Precedent Transactions -------------------------------- Time Period The Merger Mean Median - ------------------ -------------- ------------ ------------- 1-Day Prior 17.7% 26.0% 26.0% 5-Day Average 20.8% 26.6% 26.3% 10-Day Average 23.2% 28.2% 27.5% 20-Day Average 24.9% 30.3% 27.9% 30-Day Average 25.4% 29.6% 27.4% 60-Day Average 25.3% 28.9% 23.9% 90-Day Average 24.4% 27.7% 25.9% 120-Day Average 25.5% 26.9% 25.2% Synergy Payout Ratio Analysis Using publicly available information, Lehman Brothers reviewed the synergy payout ratios in the following five precedent transactions: o The British Petroleum Company p.l.c. / Amoco Corporation o Exxon Corporation / Mobil Corporation o BP Amoco p.l.c. / Atlantic Richfield Company o TOTAL S.A. / PetroFina S.A. o TOTAL Fina S.A. / Elf Aquitaine S.A. To arrive at the synergy payout ratios, Lehman Brothers first calculated the aggregate dollar value of the premium being paid by the acquiring company to the stockholders of the target company. Such premiums were calculated based on the per share premium implied by the relative performance of the acquirer's and target's common share prices over selected time periods. Lehman Brothers then compared those total dollar value amounts of the premium to the estimated net present value of the after-tax projected synergies as announced in connection with each of the five transactions. Next, Lehman Brothers prepared the same calculation for the merger based on stock price performance during various periods ending October 13, 2000 and based on $1.2 billion in estimated pre-tax cost savings expected to result from the merger. This analysis is theoretical. It assumes that mergers create shareholder value for the companies' stockholders through earnings accretion that derives from the synergies. At the same time, the analysis assumes that, from the perspective of the acquiror's stockholders, value is transferred through payment of a premium to the stockholders of the target company. The purpose of the analysis is to assess how much of the value created by the merger synergies is theoretically conveyed, or paid, to the stockholders of the target through the payment of a control premium. The analysis concludes that, in the five precedent transactions, the acquiror theoretically conveyed an average of 69.8 percent of the value created by synergies to the target stockholders in the form of premium. By comparison, the amount of the synergy value being theoretically conveyed by Chevron to Texaco's shareholders is 57.7 percent. -38-

Five Precedent Transactions -------------------------------- Time Period The Merger Mean Median - ------------------ -------------- ------------ ------------- 1-Day Prior 57.7% 69.8% 71.3% 5-Day Average 67.8% 70.1% 71.5% 10-Day Average 73.9% 73.1% 72.2% 20-Day Average 77.8% 76.5% 75.2% 30-Day Average 79.8% 74.7% 74.9% 60-Day Average 77.8% 72.6% 67.4% 90-Day Average 76.5% 71.2% 71.5% 120-Day Average 80.6% 69.4% 71.8% Pro Forma Merger Consequences Analysis Lehman Brothers analyzed the pro forma impact of the merger on Chevron's historical and projected earnings per share and discretionary cash flow per share. Historical analysis was based on net income and discretionary cash flow for both Chevron and Texaco for the 12-month period ending June 30, 2000. Projected net income and discretionary cash flow for fiscal years 2000 and 2001 was based on consensus earnings estimates for both companies as reported by First Call, a service reporting equity analyst estimates. The pro forma results reflected the following adjustments: (a) the inclusion of $1.2 billion in pretax synergies; (b) the estimated impact of a potential disposition of Texaco's joint venture interests in Equilon and Motiva; and (c) the consolidation of the Chevron's and Texaco's Caltex joint venture under unified ownership. Based on these assumptions, Lehman Brothers' analysis indicated that the merger would be accretive to Chevron's earnings per share by 4.2 percent to 4.5 percent, and would be accretive to Chevron's discretionary cash flow per share by 3.1 percent to 5.0 percent. Lehman Brothers is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. The Chevron board of directors selected Lehman Brothers because of its expertise, reputation and familiarity with Chevron and the oil and gas industry in general and because its investment banking professionals have substantial experience in transactions comparable to the merger. Lehman Brothers has previously rendered various financial advisory and investment banking services to Chevron unrelated to the merger, for which it has received compensation. During the two years prior to the announcement of the merger, Lehman Brothers was paid for such services an aggregate of $6,748,625 in fees, $5,000,000 of which were fees paid to Lehman Brothers by Chevron for financial advisory services in connection with Chevron's formation of a chemical joint venture with Phillips Petroleum Company, which was completed in July 2000. Under Chevron's engagement letter with Lehman Brothers, dated April 13, 1999, Chevron has agreed to pay Lehman Brothers upon completion of the merger an aggregate fee equal to 0.085 percent of the total consideration payable in the merger, including liabilities assumed by Chevron. If this fee were calculated as of the date of this joint proxy statement/prospectus, such fee would be approximately $39 million. In addition, Chevron has agreed to reimburse Lehman Brothers for reasonable out-of-pocket expenses incurred in connection with Lehman Brothers' work in connection with the merger and to indemnify Lehman Brothers for various liabilities that may arise out of its engagement by Chevron and the rendering of the Lehman Brothers opinion. In the ordinary course of its business, Lehman Brothers may actively trade in the debt or equity securities of Chevron and Texaco for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities. -39-

Opinion of Texaco's Financial Advisor Credit Suisse First Boston Corporation has acted as Texaco's financial advisor in connection with the merger. Texaco selected Credit Suisse First Boston based on Credit Suisse First Boston's experience, expertise, reputation and familiarity with Texaco's business. Credit Suisse First Boston is an internationally recognized investment banking firm and is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, leveraged buyouts, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. In connection with Credit Suisse First Boston's engagement, Texaco requested that Credit Suisse First Boston evaluate the fairness, from a financial point of view, to the holders of Texaco common stock of the exchange ratio provided for in the merger. On October 15, 2000, at a meeting of Texaco's board of directors held to consider the merger, Credit Suisse First Boston delivered to Texaco's board of directors its written opinion, dated October 15, 2000, to the effect that, as of that date and based on and subject to the matters described in its opinion, the exchange ratio was fair from a financial point of view to the holders of Texaco common stock. The full text of Credit Suisse First Boston's written opinion dated October 15, 2000 to Texaco's board of directors, which sets forth the procedures followed, assumptions made, matters considered and limitations on the review undertaken, is attached as Annex E and is incorporated by reference into this joint proxy statement/prospectus. Texaco stockholders are urged to read carefully this opinion in its entirety. Credit Suisse First Boston's opinion is addressed to Texaco's board of directors and relates only to the fairness to holders of Texaco common stock of the exchange ratio from a financial point of view. The opinion does not address any other aspect of the proposed merger or any related transaction and does not constitute a recommendation to any stockholder as to how to vote or act on any matter relating to the merger. The summary of Credit Suisse First Boston's opinion in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of the opinion. In arriving at its opinion, Credit Suisse First Boston reviewed the merger agreement and related documents, as well as publicly available business and financial information relating to Texaco and Chevron. Credit Suisse First Boston also reviewed other information relating to Texaco and Chevron, including financial forecasts, which Texaco and Chevron provided to or discussed with Credit Suisse First Boston, and met with the managements of Texaco and Chevron to discuss the businesses and prospects of Texaco and Chevron. Credit Suisse First Boston also considered financial and stock market data of Texaco and Chevron and compared those data with similar data for other publicly held companies in businesses similar to Texaco and Chevron and considered, to the extent publicly available, the financial terms of other business combinations and other transactions that have recently been effected. Credit Suisse First Boston also considered other information, financial studies, analyses and investigations and financial, economic and market criteria that it deemed relevant. In connection with its review, Credit Suisse First Boston did not assume any responsibility for independent verification of any of the information that was provided to, or otherwise reviewed by, it and relied on that information being complete and accurate in all material respects. With respect to financial forecasts, Credit Suisse First Boston was advised, and assumed, that the forecasts were reasonably prepared on bases reflecting the best currently available estimates and judgments of the managements of Texaco and Chevron, respectively, as to the future financial performance of Texaco and Chevron and the potential synergies and strategic benefits anticipated to result from the merger, including the amount, timing and achievability of those synergies and benefits. Credit Suisse First Boston also assumed that the merger will be treated as a pooling-of-interests in accordance with generally accepted accounting principles and will qualify as a tax-free reorganization for U.S. federal income tax purposes. In addition, Credit Suisse First Boston assumed that the merger would be completed in accordance with the terms of the merger agreement without any amendments or waivers and also assumed that in the course of obtaining the necessary regulatory and third party consents for the proposed merger and related transactions, there will be no delays, restrictions or dispositions of assets that will have a material adverse effect on the contemplated benefits of the proposed merger to the holders of Texaco common stock. Whether or not these assumptions continue to be accurate, Texaco has no legal or contractual obligation to seek an updated opinion from Credit Suisse First Boston and does not intend to do so. -40-

Credit Suisse First Boston was not requested to, and did not, make an independent evaluation or appraisal of the assets or liabilities, contingent or otherwise, of Texaco or Chevron, and was not furnished with any such evaluations or appraisals. Credit Suisse First Boston's opinion was based on information available to, and financial, economic, market and other conditions as they existed and could be evaluated by, Credit Suisse First Boston on the date of its opinion. Credit Suisse First Boston did not express any opinion as to the actual value of Chevron common stock when issued in the merger or the prices at which shares of Chevron common stock will trade after the merger. In connection with its engagement, Credit Suisse First Boston was not requested to, and did not, solicit third-party indications of interest in the possible acquisition of all or a part of Texaco. Although Credit Suisse First Boston evaluated the exchange ratio from a financial point of view, Credit Suisse First Boston was not requested to, and did not, recommend the specific consideration payable in the merger, which consideration Credit Suisse First Boston understood was determined through arm's length negotiations between Texaco and Chevron. No other limitations were imposed on Credit Suisse First Boston with respect to the investigations made or procedures followed in rendering its opinion. In preparing its opinion to Texaco's board of directors, Credit Suisse First Boston performed a variety of valuation and relative analyses, including those described below. The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances; therefore, a fairness opinion is not readily susceptible to summary description. In arriving at its opinion, Credit Suisse First Boston made qualitative judgments as to the significance and relevance of each analysis and factor that it considered. Accordingly, Credit Suisse First Boston believes that its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying its analyses and opinion. In its analyses, Credit Suisse First Boston considered industry performance, regulatory, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Texaco and Chevron. No company, transaction or business used in Credit Suisse First Boston's analyses as a comparison is identical to Texaco or Chevron or the proposed merger, and an evaluation of the results of those analyses is not entirely mathematical. Rather, the analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, business segments or transactions analyzed. The estimates contained in Credit Suisse First Boston's analyses and the ranges of valuations resulting from any particular analysis are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by the analyses. In addition, analyses relating to the value of businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold. Accordingly, Credit Suisse First Boston's analyses and estimates are inherently subject to substantial uncertainty. Credit Suisse First Boston's opinion and financial analyses were not the only factors considered by Texaco's board of directors in its evaluation of the proposed merger and should not be viewed as necessarily determinative of the views of Texaco's board of directors with respect to the exchange ratio. The following is a summary of the material analyses underlying Credit Suisse First Boston's opinion to Texaco's board of directors in connection with the merger. The financial analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the financial analyses. To understand fully Credit Suisse First Boston's financial analyses, the tables must be read together with the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses of each summary. Not doing so could create a misleading or incomplete view of Credit Suisse First Boston's financial analyses. -41-

Valuation Analysis Credit Suisse First Boston conducted three valuation analyses: o a discounted cash flow analysis, o a comparable companies analysis, and o a comparable transactions analysis. Each of these analyses compared the exchange ratio in the merger of 0.77x with the exchange ratios implied by each of these analyses. Discounted Cash Flow Analysis Credit Suisse First Boston estimated the present value of the stand-alone, unlevered, after-tax free cash flows that Texaco could produce over calendar years 2001 through 2004 and that Chevron could produce over the same period. The analysis was based on estimates of the managements of Texaco and Chevron adjusted, as reviewed by or discussed with Texaco management, to reflect, among other things, differing assumptions about future oil and gas prices. Ranges of estimated terminal values were calculated by multiplying estimated calendar year 2004 earnings before interest, taxes, depreciation, amortization and exploration expense, commonly referred to as EBITDAX, by terminal EBITDAX multiples of 6.5x to 7.5x in the case of both Texaco and Chevron. The estimated unlevered after-tax free cash flows and estimated terminal values were then discounted to present value using discount rates of 9.0 percent to 10.0 percent. That analysis indicated an implied exchange ratio reference range of 0.56x to 0.80x. Comparable Companies Analysis Credit Suisse First Boston compared financial, operating and stock market data of Texaco and Chevron to corresponding data of three categories of companies in the integrated petroleum business. Chevron and Texaco are each comparable to the companies in each of the three categories in some, but not in all, respects, though Credit Suisse First Boston believed Chevron to be somewhat more comparable to the "Super Majors" (as identified below) than was Texaco. The categories and the companies in each category are: o Super Majors: o BP Amoco p.l.c. o Exxon Mobil Corporation o Royal Dutch Petroleum Company/The Shell Transport and Trading Company p.l.c. o International Majors: o Eni S.p.A. o Repsol YPF S.A. o TOTAL Fina Elf S.A. o Domestic Integrateds: o Conoco Inc. o USX Corporation--Marathon Group o Phillips Petroleum Company -42-

Credit Suisse First Boston reviewed: o adjusted market value as a multiple of estimated EBITDAX for calendar years 2000 and 2001, o market value as a multiple of estimated after-tax cash flow for calendar years 2000 and 2001, and o market value as a multiple of estimated net income for calendar years 2000 and 2001. Market values were calculated by multiplying the October 13, 2000 stock price for the relevant company by the diluted number of shares outstanding, after taking into account option proceeds, and adjusted market values were calculated as market value plus net debt (including preferred stock and minority interests). Estimated after-tax cash flows, estimated net income and estimated EBITDAX for purposes of determining public trading multiples for the selected companies were based on Credit Suisse First Boston research and for Texaco and Chevron were based on Credit Suisse First Boston research and the adjusted management cases. The range of selected multiples for the comparable companies are indicated in the following table. In this table, "AMV" refers to adjusted market value and "MV" refers to market value. Texaco Chevron ------------------------------------ ----------------------------------- Comparable Companies Comparable Companies Reference Range Reference Range ------------------------------------ ----------------------------------- Valuation Parameter Low High Low High ------------------------------------------------------------------------------------------------------------- AMV/2000E EBITDAX 5.0x -- 6.0x 5.5x -- 6.5x AMV/2001E EBITDAX 6.0x -- 7.0x 6.5x -- 7.5x MV/2000E Cash Flow 6.0x -- 7.0x 6.5x -- 7.5x MV/2001E Cash Flow 6.0x -- 7.0x 7.0x -- 8.0x MV/2000E Net Income 11.0x -- 13.0x 11.5x -- 13.5x MV/2001E Net Income 12.0x -- 14.0x 14.0x -- 16.0x Based on the multiples shown on this table, Credit Suisse First Boston then applied a range of selected multiples for the comparable companies to corresponding financial data of Texaco and Chevron, utilizing adjusted management case estimates for Texaco and Chevron. That analysis indicated an implied exchange ratio reference range of 0.52x to 0.75x. Comparable Transactions Analysis Credit Suisse First Boston analyzed the implied transaction multiples paid in the following selected merger and acquisition transactions involving major integrated petroleum companies announced since August 1998: Date Acquiror Acquired Company -------------------------------- ------------------------------------ ------------------------------------ August 11, 1998 The British Petroleum Company p.l.c. Amoco Corporation December 1, 1998 Exxon Corporation Mobil Corporation December 1, 1998 TOTAL S.A. PetroFina S.A. April 1, 1999 BP Amoco p.l.c. Atlantic Richfield Company April 30, 1999 Repsol S.A. YPF S.A. July 5, 1999 TOTAL Fina S.A. Elf Aquitaine S.A. -43-

Credit Suisse First Boston compared market values in the selected transactions as multiples of the latest 12 months after-tax cash flow and net income, and adjusted market values as multiples of the latest 12 months EBITDAX. Market values were calculated by multiplying the announced transaction price per share for the relevant transaction by the diluted number of target company shares outstanding, after taking into account option proceeds, and adjusted market values were calculated as market value plus net debt (including preferred stock and minority interests). All multiples were based on publicly available financial information. The range of selected multiples for the comparable transactions are indicated in the following table. In this table, "AMV" refers to adjusted market value, "MV" refers to market value, and "LTM" refers to latest 12 months results based on the most recently completed four quarters for which results have been publicly reported. Reference Range --------------------------------- Valuation Parameter Low High ----------------------------------------------------------------------- AMV/LTM EBITDAX 8.5x -- 10.5x MV/LTM Cash Flow 9.0x -- 12.0x MV/LTM Net Income 22.0x -- 26.0x Based on the multiples shown in this table, Credit Suisse First Boston then applied a range of selected multiples for the selected transactions of the latest 12 months after-tax cash flow, net income and EBITDAX to corresponding financial data of Texaco and Chevron. That analysis indicated an implied exchange ratio reference range of 0.51x to 0.82x. Relative Analyses Credit Suisse First Boston also conducted two relative analyses--relative contribution analysis and historical stock trading analysis--and compared the exchange ratio in the merger of 0.77x with the exchange ratios implied by those analyses. Relative Contribution Analysis Credit Suisse First Boston performed an exchange ratio analysis, based on adjusted management case estimates of Texaco and Chevron, comparing the relative contributions of Texaco and Chevron to estimated net income and after-tax cash flows of the combined company in calendar years 2000, 2001 and 2002. No synergies were assumed in that analysis. That analysis yielded an implied exchange ratio reference range of 0.64x to 0.74x, as indicated in the following table: Texaco Chevron Percentage Percentage Implied Contribution Contribution Exchange Ratios -------------- -------------- ----------------- Net Income: 2000E 35% 65% 0.64x 2001E 37% 63% 0.70x 2002E 36% 64% 0.69x After-Tax Cash Flow: 2000E 36% 64% 0.69x 2001E 37% 63% 0.73x 2002E 38% 62% 0.74x -44-

Historical Stock Trading Analysis Credit Suisse First Boston performed an exchange ratio analysis comparing the exchange ratios implied by average daily closing stock prices for Texaco common stock and Chevron common stock on October 13, 2000, and during the one-week, one-month, three-month, six-month, one-year, two-year and three-year periods preceding October 13, 2000, and the premiums over market exchange ratios for those periods implied by the exchange ratio in the merger. That analysis indicated an implied exchange ratio reference range of 0.61x to 0.67x and is shown in the following table: Implied Premium at Merger Period Implied Exchange Ratio Exchange Ratio - ---------------------------- ------------------------ ------------------------- October 13, 2000 0.65x 17.7% One week preceding 0.63x 21.6% One month preceding 0.61x 25.3% Three months preceding 0.62x 25.1% Six months preceding 0.61x 25.9% One year preceding 0.63x 22.6% Two years preceding 0.65x 18.7% Three years preceding 0.67x 14.6% Pro Forma Merger Analysis Credit Suisse First Boston analyzed the potential pro forma effect of the merger on Chevron's estimated diluted earnings per share, commonly referred to as diluted EPS, and estimated diluted after-tax cash flow per share for calendar years 2001 and 2002, based on the adjusted management cases of Texaco and Chevron, both before and after giving effect to potential cost savings and other synergies anticipated by the management of Texaco and Chevron to result from the merger. Based on the exchange ratio in the merger of 0.77x, that analysis indicated that, in each of the years analyzed, the merger would be accretive to Chevron with synergies and dilutive without synergies on an EPS basis, and accretive both with and without synergies on an after-tax cash flow basis. The actual results achieved by the combined company may vary from projected results and the variations may be material. Other Analyses In the course of preparing its opinion, Credit Suisse First Boston also reviewed and considered other information and data and performed other analyses, including the three analyses described below. Premiums Paid in Precedent Transactions Credit Suisse First Boston compared the premiums paid in the following selected merger and acquisition transactions involving major integrated petroleum companies announced since August 1998: Date Acquiror Acquired Company ----------------------------- ------------------------------------- --------------------------- August 11, 1998 The British Petroleum Company p.l.c. Amoco Corporation December 1, 1998 Exxon Corporation Mobil Corporation December 1, 1998 TOTAL S.A. PetroFina S.A. April 1, 1999 BP Amoco p.l.c. Atlantic Richfield Company July 5, 1999 TOTAL Fina S.A. Elf Aquitaine S.A. -45-

For the precedent transactions, the one-day premiums paid ranged from 23 percent to 33 percent, compared with 18 percent for the Chevron/Texaco merger calculated using the closing stock prices for Texaco common stock and Chevron common stock on October 13, 2000, or 25 percent calculated using the average daily closing stock prices for Texaco common stock and Chevron common stock during the 30-day period leading up to October 13, 2000. Ratio of Premium Paid to Capitalized Synergies in Precedent Transactions Credit Suisse First Boston compared, for the transactions used in the premiums paid analysis described above, the ratio of the premium paid to the capitalized expected synergies. For the precedent transactions, this ratio ranged from 57 percent to 109 percent, compared with 61 percent for the Chevron/Texaco merger calculated using the closing stock prices for Texaco common stock and Chevron common stock on October 13, 2000, or 83 percent calculated using the average daily closing stock prices for Texaco common stock and Chevron common stock during the 30-day period leading up to October 13, 2000. Return on Gross Invested Capital Comparison Credit Suisse First Boston compared the ten-year average return on gross invested capital generated by each of Chevron and Texaco, and for the following parts of their respective businesses: o exploration and production--worldwide, o exploration and production--U.S. only, o exploration and production--non-U.S. only, o refining and marketing--worldwide, o refining and marketing--U.S. only, and o refining and marketing--non-U.S. only. These comparisons indicated that Texaco's return on gross invested capital was lower than Chevron's return on gross invested capital for each business segment other than worldwide and international refining and marketing. Miscellaneous Texaco has agreed to pay Credit Suisse First Boston for its financial advisory services upon completion of the merger an aggregate fee equal to 0.075 percent of the total consideration payable in the merger, including liabilities assumed by Chevron. If the merger had been completed on __________, 2001, Credit Suisse First Boston's aggregate fee would have been approximately $____ million. Texaco also has agreed to reimburse Credit Suisse First Boston for its reasonable out-of-pocket expenses, including reasonable fees and expenses of legal counsel and any other advisor retained by Credit Suisse First Boston, and to indemnify Credit Suisse First Boston and related parties against liabilities arising out of its engagement. Credit Suisse First Boston and its affiliates have in the past provided financial services to Texaco and its affiliates and to Chevron and its affiliates unrelated to the proposed merger, for which services Credit Suisse First Boston and its affiliates have received customary compensation. In the ordinary course of business, Credit Suisse First Boston and its affiliates may actively trade the debt and equity securities of both Texaco and Chevron for their own accounts and for the accounts of customers and, accordingly, may at any time hold long or short positions in such securities. Texaco's Financial Advisors In May 2000, Texaco retained Credit Suisse First Boston as its financial advisor, as more fully described above. In addition, in October 2000, Texaco retained Morgan Stanley & Co. Incorporated as financial advisor to provide additional advice with respect to this transaction. Morgan Stanley was not asked to, and did not, provide a fairness opinion with respect to the merger, but has provided advice relating to the anticipated divestitures of -46-

Equilon and Motiva which may be necessary to effect the merger. The fees to be paid Morgan Stanley are normal and customary and have been included in the overall estimate of $125 million of merger-related expenses. INTERESTS OF DIRECTORS AND OFFICERS IN THE MERGER In considering the recommendation of the Texaco board with respect to the merger agreement, Texaco stockholders should be aware that members of the management of Texaco and the Texaco board have interests in the merger that may be different from, or in addition to, the interests of the other stockholders of Texaco generally. Board of Directors Chevron has agreed that as of the closing of the merger it will expand its board of directors to 15 members and, in part by filling the resulting vacancies, will appoint to the ChevronTexaco board Mr. Tilton and five other persons who immediately prior to the closing were directors of Texaco. See "The Merger Agreement--ChevronTexaco Board and Related Matters" on page 65. It is expected that in addition to Mr. Tilton, ____________________, _________________, _________________, _________________, and __________________, will be the directors of Texaco who will be nominated by Texaco for election to the ChevronTexaco board as of the closing. Texaco's directors will not receive any special payments as the result of the merger, although payment of certain amounts previously earned will be accelerated. Executive Officers After the merger, some Texaco executives will become executives of ChevronTexaco. Glenn F. Tilton, currently Texaco's Chairman and Chief Executive Officer, will become a Vice Chairman of ChevronTexaco. Discussions have been held with Mr. Tilton regarding the terms of his post-merger employment, but no agreement has been reached. Janet Stoner, currently Texaco's Vice President for Human Resources, and Rosemary Moore, currently Texaco's Vice President for Corporate Communications and Government Affairs, will both have similar positions with ChevronTexaco. Ms. Stoner and Ms. Moore are each eligible to receive a retention bonus approximately equivalent to the applicable "base pay severance" and "bonus severance" payments described below payable within three years following the closing of the merger. Other than salary increases in the ordinary course and the arrangements described above, the only change in compensation for a Texaco executive officer since the announcement of the merger is the promotion of Mr. Tilton from Senior Vice President to Chairman and Chief Executive Officer and a corresponding increase in his annual base salary effective February 4, 2001 from $426,300 to $889,600. Mr. Tilton's bonus and long term awards for 2001 will be based on his new position. Since the announcement of the merger, Peter I. Bijur has resigned as Chairman and Chief Executive Officer of Texaco, and Deval Patrick has resigned as Vice President and General Counsel of Texaco. Texaco's executive officers are entitled to benefits under their individual severance agreements if they do not continue employment with ChevronTexaco. The amounts payable under the severance agreements are slightly more than three times annual cash compensation. These agreements are described on pages 48 and 49. Assuming that the closing occurs on July 1, 2001 and all Texaco executives who are party to severance agreements are terminated without cause or resign for good reason immediately following that date, the amount of the cash severance payments payable to these executives would be approximately $50 million and the gross-up payment would not be expected to exceed approximately $40 million. In addition, the Compensation Committee of the Texaco board may, in its discretion, award special cash bonuses totaling up to $15 million in the aggregate. No decision regarding any such payments has been made. Some executive officers, as well as other Texaco employees, may receive payments under this program. -47-

Indemnification; Directors' and Officers' Insurance Chevron has agreed to indemnify, to the extent provided under Texaco's certificate of incorporation and by-laws in effect on October 15, 2000, the individuals who on or before the closing were officers, directors and employees of Texaco or its subsidiaries with respect to all acts or omissions before the closing by these individuals in these capacities. Chevron has further agreed to cause Texaco to honor all its indemnification agreements, including under Texaco's by-laws, in effect on October 15, 2000. Chevron has also agreed to provide, for six years after the closing, directors' and officers' liability insurance in respect of acts or omissions occurring before the closing covering each person currently covered by Texaco's directors' and officers' liability insurance policy, up to 300 percent of the per annum rate of premium paid by Texaco. See "The Merger Agreement--Covenants--Indemnification and Insurance of Texaco Directors and Officers" on page 69. Severance Agreements Twenty Texaco executives have severance agreements with Texaco, which expire as of the first day of the month immediately following the executive's 65th birthday. An executive will be entitled to the severance benefits set forth in the severance agreements if, after the date of first contact by a party, or a party's representative, with Texaco which results in a "change of control" (as defined in the severance agreements) involving that party or its affiliate and up to 36 months after a change of control, either the executive's employment is terminated without "just cause" (as defined in the severance agreements) or the executive resigns for "good reason." Under the severance agreements, an executive will be deemed to resign for good reason if he or she resigns within 60 days after: o a reduction in the executive's base pay; o a reduction in the executive's cash bonus in excess of 20 percent of the prior year's award (unless the reduction is due to Texaco's performance under the objective measurements of Texaco's Incentive Bonus Plan effective immediately before the change of control or under the objective measurements of an incentive compensation program with target bonuses and performance goals comparable to and not materially less favorable to the executive than the targets and goals described in the Incentive Bonus Plan in existence prior to the change of control); o the assignment of any duties inconsistent with the position in Texaco that the executive held immediately prior to the change of control or a significant adverse alteration in the nature or status of the executive's responsibilities or condition of employment from those in effect immediately prior to such change of control; o the failure of Texaco to continue in effect any material compensation or benefit plan in which the executive participated immediately prior to the change of control, unless an equitable arrangement (embodied in an ongoing substitute or alternate plan) has been made with respect to such plan, or the failure by Texaco to continue the executive's participation in such material compensation or benefit plan (or in such substitute or alternative plan) on a basis not materially less favorable, both in terms of the amount of benefits provided and the level of the executive's participation relative to other participants, as that which existed at the time of the change of control, unless any such change is independently justified based on peer group practices; or o the requirement to relocate to a work location which is 50 or more miles from the executive's former work location, without the executive's consent. If there is a change of control and the executive is terminated without just cause or resigns for good reason within three years thereafter, a typical executive will be entitled to receive a cash payment, except as otherwise provided below, equal to the following (although benefits may vary slightly on a case by case basis): o "base pay severance" equal to thirty-six months' base pay, which means the monthly base salary in effect immediately before the change of control or, if greater, the base salary during the year immediately before the executive's termination without just cause or resignation for good reason; plus o "bonus severance" equal to three times the highest cash bonus earned by the executive in any of the five years preceding the executive's termination date (if the executive has not yet earned a company -48-

bonus prior to the change of control, then the executive's target bonus will be used in this regard); plus o three times the annual value of benefits earned or accrued by the executive as a result of the executive's participation in the following plans immediately preceding the change of control or immediately preceding the executive's resignation, whichever is greater: o in lieu of additional service credit under the retirement and supplemental plans, a cash payment equal to 10 percent of the amount of the total of base pay severance and bonus severance; plus o in lieu of additional contributions to the thrift and supplemental plans, a cash payment equal to 6 percent of the amount of base pay severance; plus o if the executive is not eligible for retiree medical coverage under the bullet immediately below, a cash payment equal to three times the annual company contribution to the Texaco comprehensive medical plan (or alternate sponsored medical plan or HMO) for the executive's elected coverage option. o executives who are age 45 or older with at least ten years of service will receive retiree medical coverage under the terms and conditions that existed immediately prior to the change of control with the full company portion of the premium paid by the company. In order to qualify, the executive must have been covered under a company-sponsored medical plan immediately prior to the change of control or immediately prior to termination of employment; o executives who are age 45 or older with at least ten years of service will receive full retiree life insurance coverage under the terms and conditions that existed immediately prior to the change of control with the full amount of insurance paid by the company. In order to qualify for retiree life insurance, the executive must have participated in contributory life insurance coverage immediately prior to the date of the change of control or immediately prior to termination of employment; o outplacement services with a nationally recognized outplacement firm, with a cost not to exceed $15,000; plus o continued participation under the terms and practices of the company's tax assistance plan for the year of termination or resignation and three calendar years immediately following. Notwithstanding the above, if the executive is within 36 months of attaining age 65 at the time of termination of employment or resignation, the benefits described in the first three bullets above will be reduced by multiplying such benefit amounts by a fraction the numerator of which is the number of full and partial months from the date the executive terminates employment to the last day of the month he or she turns age 65, and the denominator of which is 36 months. Under the severance agreements, Texaco is required, if necessary, to make an additional gross-up payment to any executive to offset fully the effect of any excise tax imposed by Section 4999 of the Internal Revenue Code on any excess parachute payment, whether made to that executive under the severance agreements or otherwise. In general, Section 4999 imposes an excise tax on the recipient of any excess parachute payment equal to 20 percent of that payment. A parachute payment is any payment contingent on a change of control that equals or exceeds three times the executive's "base amount", which is defined as average taxable compensation received by the executive from the employer during the five taxable years preceding the year in which the change of control occurs. Excess parachute payments consist of the excess of parachute payments over an individual's base amount. If the individual has been employed for fewer than five taxable years, all years of employment preceding the year in which the change of control occurs will be used to calculate the excess parachute payment. Severance benefits received by the executive under the severance agreements will be made in lieu of and will replace any benefit entitlements under the U.S. Separation Pay Plan. The merger will constitute a change of control under the severance agreements. Assuming that the closing occurs on July 1, 2001 (which assumption may not be valid) and all of the Texaco executives who are party to the severance agreements are terminated without just cause or resign for good reason immediately following that date, the amount of the cash severance payments payable to all of the Texaco executive officers who are party to the -49-

severance agreements would be approximately $50 million and the gross-up payment payable would not be expected to exceed approximately $40 million. Employee Severance Benefits Texaco maintains severance pay programs in most locations around the world. In general, all regular, full-time Texaco employees on the U.S. payroll are eligible to participate in the U.S. Separation Pay Plan. Under the terms of the U.S. Separation Pay Plan, benefits will be provided to all eligible employees if their employment is terminated or the conditions of their employment are changed adversely within two years following a change of control. The severance pay programs maintained outside the United States are designed to be competitive locally and do not provide special change of control benefits. Under the U.S. Separation Pay Plan, an eligible Texaco employee will receive change of control benefits if any of the following occurs within two (2) years after a change of control of Texaco: o the employee's employment is terminated without "just cause" (as defined in the U.S. Separation Pay Plan); o the employee resigns within 60 days after: o a reduction in the employee's base pay; or o a reduction in approved overtime (other than an across-the-board cut for operational reasons); or o a reduction in the employee's cash bonus or cash stipend bonus in excess of 20 percent of the employee's prior year award (unless the reduction is due to Texaco's performance under the objective measurements of its incentive bonus plan effective immediately before the change of control or under the objective measurements of an incentive compensation program with target bonuses and performance goals comparable to and not materially less favorable to the employee than the targets and goals described in Texaco's incentive bonus plan in existence prior to the change of control); or o a reduction in the employee's position or position grade or any equivalent action; or o the benefits under one or more of the benefit plans or perquisites in which the employee may participate at the time of the change of control are reduced or terminated (except as required by law) unless any such change is independently justified based on peer group practices; or o being required to relocate to a work location which is 50 or more miles from the employee's former work location, without the employee's consent. The change of control benefits consist of an amount equal to the following: o "base pay benefit" - one month's base pay (which means the greater of the monthly rate of pay in effect immediately prior to the change of control or during the highest paid month in the year immediately prior to the employee's termination or resignation) for each completed or partial year of service up to a maximum of 24 months' base pay (minimum of 3 months' base pay if the employee has at least one year of service); plus o "bonus and overtime benefit" - 1/12th of the employee's highest cash bonus, PCP award, cash stipend bonus, merit stipend or annual overtime pay received in any of the five years immediately preceding the employee's termination and qualifying resignation, multiplied by the same number of months used to calculate the employee's base pay benefit; plus o the benefit plans make-up payment equal to the sum of: o retirement plan - 10 percent of the sum of the base pay benefit and the bonus and overtime benefit; o thrift plan - 6 percent of the base pay benefit; and -50-

o medical plan - company's monthly contribution to the Texaco comprehensive medical plan (or alternate company-sponsored medical plan or HMO), for the employee's elected coverage option either immediately preceding a change of control or immediately preceding the employee's termination or qualifying resignation, whichever is greater, multiplied by the number of years of service determined in calculating the base pay benefit; o "retiree medical coverage" - employees who are age 45 with at least 10 years of service will receive retiree medical coverage. Employees with 20 or more years of service will receive 100 percent of Texaco's contribution. Texaco's contribution will be pro-rated downward 5 percent per year for years of service less than 20. In order to qualify for retiree coverage, the employee must have been covered under a Texaco- sponsored medical plan immediately prior to the change of control or immediately prior to termination or qualifying resignation. Employees who are not eligible for retiree medical can participate in the Texaco- sponsored medical plan at their own expense for three years following termination (inclusive of COBRA coverage); and o "retiree life insurance coverage" - employees age 45 or older with at least 10 years of service will be eligible for Texaco-provided retiree life insurance coverage. Employees with 20 or more years of service will receive 100 percent retiree life insurance coverage. Coverage is reduced 5 percent per year for each year of service below 20 years. The amount of coverage will be determined based on the employee's level of participation in Texaco's term life insurance plan immediately prior to the date of the change of control or immediately prior to termination or qualifying resignation; and o "retirement plan" - more favorable early commencement discount factors will apply when an employee starts his or her pension at age 50 or older, even if the employee leaves Texaco before age 50. Social security offset in the final average pay formula will not apply until age 62, if the employee starts pension before age 62. Also, employees in Grade 20 or higher qualifying for benefits under the U.S. Separation Pay Plan will be entitled to the following supplemental benefit. In determining years of company service under the first bullets above setting forth benefits to be provided to eligible participants in the separation pay plan upon a change of control, employees will be credited with a minimum of twelve years of deemed service plus (a) for employees in Grade 20, one additional year for each actual completed or partial year of company service; (b) for employees in Grade 21, one and one-half additional years for each actual completed or partial year of company service; or (c) for employees in Grades 22 and above, two additional years for each actual completed or partial year of company service. In no event will the aggregate years of service, actual and deemed, used in determining benefits under the U.S. Separation Pay Plan exceed 24 years of service. Under the U.S. Separation Pay Plan, Texaco is required, if necessary, to make an additional gross-up payment to any employee to offset fully the effect of any excise tax imposed by Section 4999 of the Internal Revenue Code on any excess parachute payment. The merger will constitute a change of control under the U.S. Separation Pay Plan. If the closing occurs on July 1, 2001 and if all of the eligible Texaco employees are terminated without just cause or resign for the specified reasons immediately following that date, the amount of the cash severance payment payable to all of the U.S. Texaco employees would be approximately $1.2 billion and the gross-up payment payable would not be expected to exceed approximately $25 million. Stock Incentive Plans At the effective time, each outstanding option granted by Texaco to purchase shares of Texaco common stock will cease to represent a right to acquire shares of Texaco common stock and will, after the effective time, constitute an option to acquire, on the same terms and conditions as applied to the Texaco stock option prior to the effective time, the number, rounded to the nearest whole number, of shares of ChevronTexaco common stock determined by multiplying: o the number of shares of Texaco common stock subject to the option immediately before the effective time by -51-

o the exchange ratio. The exercise price of each of these options will be a price per share of ChevronTexaco common stock, rounded to the nearest one-hundredth of a cent, equal to: o the per share exercise price for Texaco common stock that otherwise could have been purchased under the Texaco stock option divided by o the exchange ratio. As of December 31, 2000, options to purchase 13,719,638 shares of Texaco common stock were outstanding, with a weighted average exercise price of $61.95 per share. Of these outstanding options, options to purchase 9,657,813 shares were exercisable, with a weighted average exercise price of $63.35 per share. Under the merger agreement, each other stock-based award granted by Texaco under its employee or director plans or arrangements maintained as of October 15, 2000 will be vested and converted, as of the effective time, into a similar ChevronTexaco stock-based award, adjusted as appropriate to preserve the award's inherent value. The other terms and conditions of these other stock-based awards, and the plans or agreements under which they were issued, will continue to apply in accordance with their terms and conditions as these terms and conditions have been interpreted and applied by Texaco in accordance with its past practice, but with such adjustments as are necessary or appropriate in light of the merger. Stock Grantor Trust Texaco maintains a stock grantor trust which secures Texaco's obligations under various employee benefit and executive compensation programs, including the obligations under the severance agreements. As of December 31, 2000, the stock grantor trust held assets valued at approximately $572 million. The stock grantor trust will continue to hold assets following the merger. -52-

Following the merger, ChevronTexaco common stock will be traded on the NYSE under the ticker symbol "CHV." -53-

The merger agreement permits Chevron and Texaco to pay, prior to the closing, regular quarterly cash dividends to holders. The merger agreement also permits the subsidiaries of Chevron and Texaco to pay, prior to the closing, regular periodic cash or other required dividends to holders. The parties have agreed in the merger agreement to coordinate the declaration of dividends and the related record dates and payment dates so that Texaco stockholders do not receive two dividends, or fail to receive one dividend, for any single calendar quarter with respect to their Texaco shares and the ChevronTexaco shares to be received by them in the merger. Chevron and Texaco expect that the combined company will continue to pay quarterly dividends on ChevronTexaco common stock after completion of the merger. The payment of dividends by ChevronTexaco in the future will continue to depend on business conditions, ChevronTexaco's financial condition and earnings, and other factors. Effect of Merger on Texaco Investor Services Plan Upon completion of the merger, Texaco's Investor Services Plan will terminate. In its place, ChevronTexaco's investment program will be available to former Texaco stockholders. For each Texaco plan participant, the procedures for transitioning to ChevronTexaco's investment program will depend on how the participant's shares are held when the merger closes, as follows: If the Texaco shares in a plan participant's account are held in book-entry form by the custodian, shares of ChevronTexaco, including any interest in a fractional portion of a share, will be automatically issued in exchange for the Texaco shares and the participant will automatically be rolled over into ChevronTexaco's investment program. If the Texaco shares in a plan participant's account are held in certificated form, ChevronTexaco shares will not be automatically issued in exchange for the Texaco shares. Instead, participants holding Texaco stock certificates will be required to exchange their certificates for shares of ChevronTexaco. In this case, you will receive instructions on how to exchange your shares. Once a participant receives the ChevronTexaco certificates, he or she can enroll those shares in ChevronTexaco's investment program. Upon completion of the merger, the participation preferences of Texaco plan participants will be automatically carried forward into ChevronTexaco's investment program to the extent practicable. However, the mechanics of merging records may require that certain provisions of the Texaco plan be suspended or that participants receive a dividend in cash. ChevronTexaco's investment program will require participants to pay fees for certain services including the reinvestment of dividends. Should they so desire, Texaco plan participants will be provided with an opportunity to terminate or revise their plan enrollment to avoid participation in any fee-based plan services. Texaco plan participants will receive additional information regarding ChevronTexaco's investment program as soon as practicable following the merger. -54-

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS ----------------------------------------------------------- The following unaudited pro forma condensed combined financial statements combine the historical consolidated balance sheet and statements of income of Chevron and Texaco, giving effect to the merger using the pooling-of-interests method of accounting for a business combination. The financial statements also reflect the consolidation of entities jointly owned by Chevron and Texaco, primarily the Caltex Group (Caltex) of equity affiliates. We are providing the following information to aid you in your analysis of the financial aspects of the merger. We derived this information from the audited financial statements of Chevron, Texaco and Caltex for the years 2000, 1999 and 1998. The information is only a summary and you should read it together with the historical financial statements and related notes contained in the annual reports and other information filed with the SEC and incorporated by reference. See "Where You Can Find More Information" on page 85. The unaudited pro forma condensed combined statements of income assume the merger was effected on January 1, 1998. The unaudited pro forma condensed combined balance sheet gives effect to the merger as if it had occurred on December 31, 2000. Since accounting policies of the combining companies are substantially comparable, we did not make any conforming accounting policy adjustments to the unaudited pro forma condensed combined financial statements. The unaudited pro forma combined financial information is for illustrative purposes only. The financial results may have been different had the companies actually been combined. Further, unaudited pro forma condensed combined financial statements do not reflect the effect of any asset dispositions that may be required by order of regulatory agencies. See note 7 on page 62 for more information. You should not rely on the unaudited pro forma combined financial information as being indicative of the historical results that would have been achieved had the companies been combined during the periods or the future results that the combined company will experience after the merger. -55-

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS - -------------------------------------------------------------------- Note 1. Basis of Presentation The unaudited pro forma condensed combined statements of income are based on the audited consolidated financial statements of Chevron and Texaco for the years ended December 31, 2000, 1999 and 1998. The unaudited pro forma condensed combined balance sheet is based on the audited consolidated financial statements of Chevron and Texaco at December 31, 2000. The financial statements also reflect the consolidation of entities commonly owned by Chevron and Texaco, primarily Caltex. We have presented the consolidating financial data of Caltex separately from other pro forma adjustments to aid your analysis of all pro forma adjustments. Chevron and Texaco consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States and require estimates that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. In the opinion of Chevron and Texaco, the unaudited pro forma condensed combined financial statements include all adjustments necessary to present fairly the results of the periods presented. The unaudited pro forma combined financial information is for illustrative purposes only. The financial results may have been different had the companies always been combined. You should not rely on the unaudited pro forma combined financial information as being indicative of the historic results that would have been achieved had the companies actually been combined or the future results that the combined company will experience after the merger. Note 2. Accounting Policies and Financial Statement Classifications Since the accounting policies of the combining companies are substantially comparable, we did not make any accounting policy conformance adjustments to the unaudited pro forma condensed combined financial statements. Certain revenues, costs and other deductions in the consolidated statements of income for Texaco and Caltex have been reclassified to conform to the line-item presentation in the unaudited pro forma condensed combined statements of income. Certain assets and liabilities in the consolidated balance sheets for Texaco and Caltex have been reclassified to conform to the line-item presentation in the unaudited pro forma condensed combined balance sheet. Note 3. Unaudited Pro Forma Combined Net Income Per Share and Dividends Per Share The unaudited pro forma combined net income per common share is based on net income less preferred stock dividends and the weighted average number of outstanding common shares. Diluted net income per common share includes the effect of dilutive securities, including stock options. The historical weighted average number of outstanding common shares has been adjusted to reflect the exchange ratio of 0.77 shares of ChevronTexaco common stock for each share of Texaco common stock. The pro forma combined dividends per share reflect the sum of the dividends paid by Chevron and Texaco divided by the number of shares that would have been outstanding for the periods, after adjusting the Texaco shares for the exchange ratio of 0.77 shares of ChevronTexaco common stock. Note 4. Intercompany Transactions Intercompany sales and purchase transactions among Chevron, Texaco and Caltex have been eliminated in the unaudited pro forma condensed combined statements of income. Intercompany amounts receivable and payable have been eliminated in the unaudited pro forma condensed combined balance sheet. Note 5. Merger-Related and Integration-Related Expenses Merger-related fees and expenses, consisting primarily of SEC filing fees; fees and expenses of investment bankers, attorneys and accountants; and financial printing and other related charges, are estimated to be approximately $125 -61-

million. Through December 31, 2000, approximately $25 million had been incurred. The remaining fees and expenses of $100 million have been reflected in the unaudited pro forma condensed combined balance sheet as of December 31, 2000. Though not yet fully quantified, significant costs will be incurred for employee severance and other integration-related expenses, including the elimination of duplicate facilities, operational realignment and workforce reductions. These expenditures are necessary to reduce the costs of ongoing operations and to operate more effectively. These amounts will be charged to operations in the appropriate periods and, therefore, are not reflected in the unaudited pro forma condensed combined financial statements. The unaudited pro forma condensed combined financial statements reflect neither the impact of these charges nor the benefits from the expected synergies. Note 6. Other Pro Forma Adjustments (A) Pro forma adjustments have been made to consolidate the accounts of Caltex, which is owned 50 percent each by Chevron and Texaco. Both companies accounted for their respective investments in Caltex using the equity method. (B) Pro forma adjustments have been made to consolidate the accounts of P.T. Mandau Cipta Tenaga Nusantara, an Indonesian company, which is owned jointly by the combining companies and which was accounted for by Chevron and Texaco using the equity method. (C) Pro forma adjustments have been made for certain accounts relating to Fuel and Marine Marketing LLC (FAMM), which is owned 69 percent by Texaco and 31 percent by Chevron. Texaco consolidated the results of FAMM and recorded entries to reflect Chevron's minority interest. Chevron accounted for its share of FAMM using the equity method. (D) A pro forma adjustment has been made to reflect the cancellation of approximately 18 million shares of Texaco common stock accounted for as treasury stock and the assumed issuance of approximately 420 million shares of Chevron common stock in exchange for all of the outstanding Texaco common stock (based on the exchange ratio of 0.77). The actual number of shares of Chevron common stock to be issued in connection with the merger will be based on the number of shares of Texaco common stock issued and outstanding at the effective time. (E) A pro forma adjustment has been made for the redemption of Texaco's 1,200 Market Auction Preferred Shares at their liquidation preference of $250,000 per share as provided for in the Merger Agreement. (F) A pro forma adjustment has been made to reclassify 24,999 shares of Chevron and 20,640 shares of Texaco owned by Caltex at December 31, 2000 to treasury stock, at cost. The Texaco shares have been converted to Chevron stock at the exchange ratio of 0.77. The shares reclassified to treasury stock have been excluded from the pro forma number of shares outstanding at December 31, 2000. Note 7. Expected Asset Dispositions We anticipate that the Federal Trade Commission will require certain asset dispositions as a condition of not challenging the merger. While the scope and method of such dispositions are not fully known at this time, we do anticipate being required to make divestitures of Texaco's interests in two joint ventures involved in the United States refining, marketing and transportation businesses in order to address market concentration concerns. We believe that we will be able to resolve these concerns by the disposition of Texaco's interests in Equilon and Motiva. Since discussions with the FTC are ongoing, the unaudited pro forma condensed combined financial statements do not include any adjustments for the anticipated divestiture of Equilon and Motiva or for any other operations of the combined company. At December 31, 2000, Texaco's combined investment in Equilon and Motiva, in millions, was $2,467. For the year ended December 31, 2000, Texaco's combined after-tax equity in net income of Equilon and Motiva, in millions, was $198. -62-

See note 6 on page 62 for more information about MCTN. -63-

THE MERGER AGREEMENT The following summary highlights material terms of the merger agreement. This summary is qualified by reference to the complete text of the merger agreement, which is incorporated by reference into this booklet and attached as Annex A. We urge you to read the full text of the merger agreement. Structure of the Merger Under the merger agreement, a Chevron subsidiary will merge with and into Texaco so that Texaco becomes a wholly-owned subsidiary of ChevronTexaco. Timing of Closing We expect that the closing will occur on the day on which the last of the conditions set forth in the merger agreement has been satisfied or waived. Under the merger agreement, Texaco may not hold its stockholder meeting until such time at which, in the reasonable judgment of Chevron and Texaco, all conditions to closing (other than Texaco stockholder approval) have been satisfied or are then capable of being satisfied or to the extent legally permissible have been waived by the applicable party. As such, assuming Texaco stockholders approve the merger, we expect to close the transaction immediately after the Texaco stockholders meeting. Immediately upon the closing of the merger, we will file a certificate of merger with the Secretary of State of the State of Delaware, at which time the merger will be effective. The Chevron name change will only take effect if the merger closes and Chevron stockholders have approved the name change. Merger Consideration The merger agreement provides that each share of Texaco common stock outstanding immediately prior to the effective time will, at the effective time, be converted into the right to receive 0.77 shares of ChevronTexaco common stock. However, any shares of Texaco common stock held by Texaco as treasury stock or owned by Chevron or any subsidiary of Chevron will be canceled without any payment for those shares. Shares held in Texaco's stock grantor trust will not be treated as treasury stock for this purpose. Treatment of Texaco Stock Options; Other Texaco Stock-Based Awards At the effective time, each outstanding option granted by Texaco to purchase shares of Texaco common stock will be converted into an option to acquire ChevronTexaco common stock having the same terms and conditions as the Texaco stock option had before the effective time. The number of shares that the new ChevronTexaco option will be exercisable for and the exercise price of the new ChevronTexaco option will be adjusted in accordance with the exchange ratio in the merger. Each other stock-based award granted by Texaco under its employee or director plans or arrangements maintained as of October 15, 2000 will be converted, as of the effective time, into a similar ChevronTexaco stock-based award, adjusted as appropriate to preserve the award's inherent value. For additional information on Texaco stock-based awards, see "Interests of Directors and Officers in the Merger" on page 47. Exchange of Shares We will appoint an exchange agent to handle the exchange of Texaco stock certificates in the merger for ChevronTexaco stock and the payment of cash for fractional shares of ChevronTexaco stock. Soon after the closing, the exchange agent will send to each holder of Texaco stock a letter of transmittal for use in the exchange and instructions explaining how to surrender Texaco stock certificates to the exchange agent. Holders of Texaco stock who surrender their certificates to the exchange agent, together with a properly completed letter of transmittal, will receive the appropriate merger consideration. Holders of unexchanged shares of Texaco stock will not be entitled to receive any dividends or other distributions payable by ChevronTexaco after the closing until their certificates are surrendered. Exchange procedures for participants in Texaco's Investor Services Plan are described on page 54 under "Effect of Merger on Texaco Investor Services Plan." -64-

ChevronTexaco will not issue any fractional shares in the merger. Holders of Texaco common stock will receive a cash payment in the amount of the proceeds from the sale of their fractional shares in the market. ChevronTexaco Board and Related Matters Chevron has agreed to take the necessary corporate action so that, as of the closing: o The ChevronTexaco board size will be increased to 15 directors. o Mr. Tilton will become a Vice Chairman of the ChevronTexaco board. o Five directors of Texaco designated by Texaco, in addition to Mr. Tilton, will also become directors of ChevronTexaco. o At least one Texaco designee will become a member of each committee of the ChevronTexaco board. Covenants Each of Chevron and Texaco has undertaken various covenants in the merger agreement. The following summarizes the more significant of these covenants. No Solicitation. Each of Chevron and Texaco has agreed that it and its subsidiaries and their officers, directors, employees and advisers will not take action to solicit or encourage an offer for an alternative acquisition transaction involving Chevron or Texaco. An "alternative acquisition transaction" is any offer or proposal for, or indication of interest in, any: o direct or indirect acquisition or purchase of a business or asset of Chevron or Texaco or any of its subsidiaries that constitutes 20 percent or more of the net revenue, net income or assets of Chevron or Texaco and its subsidiaries, taken as a whole; o direct or indirect acquisition or purchase of 20 percent or more of any class of equity securities of Chevron or Texaco or of any of its subsidiaries whose business constitutes 20 percent or more of the net revenue, net income or assets of Chevron or Texaco and its subsidiaries, taken as a whole; o tender offer or exchange offer that, if completed, would result in any person owning 20 percent or more of any class of equity securities of Chevron or Texaco, or any of its subsidiaries whose business constitutes 20 percent or more of the net revenue, net income or assets of Chevron or Texaco and its subsidiaries, taken as a whole; or o merger, consolidation, business combination, joint venture, partnership, recapitalization, liquidation, dissolution or similar transaction involving Chevron or Texaco or any of its subsidiaries whose business constitutes 20 percent or more of the net revenue, net income or assets of Chevron or Texaco and its subsidiaries, taken as a whole. Excluded from this definition are transactions by Chevron that would not materially delay the merger and that are otherwise not prohibited by the merger agreement, and the disposition by Texaco of its interests in Equilon and Motiva. Restricted actions include engaging in discussions or negotiations with any potential bidder, disclosing non-public information or affording access to their properties, books or records to a potential bidder. These actions are permitted in response to an unsolicited bona fide offer so long as prior to doing so: o the Chevron or Texaco board, as applicable, concludes in good faith, after receipt of the advice of a financial advisor of nationally recognized reputation and outside legal counsel, that such offer is reasonably likely to result in a superior proposal with respect to Chevron or Texaco, as applicable; o Chevron or Texaco, as applicable, complies with all of its obligations under the merger agreement; and -65-

o the Chevron or Texaco board, as applicable, receives from such person an executed confidentiality agreement with terms no less favorable to Chevron or Texaco and no less restrictive to such person than those contained in the existing confidentiality agreement between Chevron and Texaco. Any party must keep the other informed of the identity of any potential bidder and the terms and status of any offer. Texaco Board's Covenant to Recommend. The Texaco board has agreed to recommend the approval and adoption of the merger agreement to Texaco's stockholders. However, the Texaco board is permitted not to make this recommendation or to withdraw or modify it in a manner adverse to Chevron if: o Texaco has received a superior proposal; o the Texaco board determines in its good faith judgment, after receiving the advice of outside legal counsel, that in light of the superior proposal, failure to withdraw or modify its recommendation would be reasonably likely to be inconsistent with fulfilling its fiduciary duty to stockholders under applicable law; o Texaco has given Chevron five business days' advance written notice of its decision to withdraw or modify its recommendation; o Texaco has given Chevron the opportunity to propose revisions to the merger agreement in response to the superior proposal and negotiated in good faith with Chevron with respect to those revisions; and o Texaco has complied with its obligations under the no solicitation covenant described above under "No Solicitation." Even if the Texaco board changes, in a manner adverse to Chevron, its recommendation in favor of the merger, Texaco must still call a stockholders' meeting as otherwise required by the merger agreement to vote on the approval and adoption of the merger agreement and the merger. Chevron Board's Covenant to Recommend. The Chevron board has agreed to recommend to Chevron's stockholders the approval of the issuance of common stock in the merger and the amendment of Chevron's restated certificate of incorporation to change its name. However, the Chevron board is permitted not to make this recommendation, or to withdraw or modify it in a manner adverse to Texaco if: o Chevron has received a superior proposal; o the Chevron board determines in its good faith judgment, after receiving the advice of outside legal counsel, that in light of the superior proposal, failure to withdraw or modify its recommendation would be reasonably likely to be inconsistent with fulfilling its fiduciary duty to stockholders under applicable law; o Chevron has given to Texaco five business days' advance written notice of its decision to withdraw or modify its recommendation; o Chevron has given Texaco the opportunity to propose revisions to the merger agreement in response to the superior proposal and negotiated in good faith with Texaco with respect to those revisions; and o Chevron has complied with its obligations under the no solicitation covenant described above under "No Solicitation." Even if the Chevron board changes, in a manner adverse to Texaco, its recommendation in favor of the merger, Chevron must still call a stockholders' meeting as otherwise required by the merger agreement to vote on the common stock issuance and the name change amendment. The merger agreement provides that the Chevron stockholders' meeting may be held on the same date as the Texaco stockholders' meeting, but that it must conclude prior to the Texaco stockholders' meeting. -66-

Interim Operations of Chevron and Texaco. Each of Chevron and Texaco has undertaken a separate covenant that places restrictions on it and its subsidiaries until either the merger becomes effective or the merger agreement is terminated. In general, Chevron and its subsidiaries and Texaco and its subsidiaries are required to conduct their business in the ordinary course consistent with past practice and in a manner not representing a new strategic direction and to use their reasonable best efforts to preserve intact their business organizations and relationships with third parties. The companies have also agreed to some specific restrictions which are subject to exceptions described in the merger agreement. The following table summarizes the more significant of these restrictions undertaken by each company: Restricted actions: Chevron Texaco Amendment of its organizational documents |X| |X| Entering into any merger, liquidation or other significant transaction |X| |X| Issuance or disposal of equity securities, options or other securities convertible into or exercisable for equity securities |X| |X| Split, combination or reclassification of its capital stock |X| |X| Declaration of dividends, except for regular quarterly or periodic cash or other required dividends as they may periodically be increased consistent with past practice |X| |X| Redemption or repurchase of its capital stock |X| |X| Amendment of the terms of any outstanding stock options |X| Capital expenditures except within the budget for a given year, subject to ordinary course exceptions |X| Increase in employee compensation or benefits except for normal ordinary course increases consistent with past practice |X| Acquisition of material assets, except in ordinary course consistent with past practice |X| Disposal of material assets, except in ordinary course consistent with past practice or under existing commitments |X| |X| Entering into any material joint venture or partnership |X| Any tax election or change in an existing tax election relating to a material tax liability |X| |X| Entering into any agreement that would prevent ChevronTexaco or any of its subsidiaries from competing in any line of business or geographic area |X| Changing accounting policies |X| |X| Any other action that would make any representation or warranty by it inaccurate in any material respect |X| |X| Any action that delays or impedes the merger |X| |X| -67-

Best Efforts Covenant. Chevron and Texaco have agreed to cooperate with each other and use their best efforts to take all actions and do all things necessary or advisable under the merger agreement and applicable laws to complete the merger and the other transactions contemplated by the merger agreement. However, neither Chevron nor Texaco is required to take any action if that action would reasonably be expected to result in a material adverse effect on Chevron, Texaco and their subsidiaries, taken as a whole, following the merger. Chevron and Texaco anticipate that there will be objections raised by the FTC to the combination of Chevron's U.S. downstream operations with Texaco's alliance interests in two joint ventures, Equilon Enterprises LLC and Motiva Enterprises LLC. In this regard, Texaco and Chevron have agreed to jointly determine how to promptly address any FTC objections to the merger. If any such objections require negotiations regarding Equilon and Motiva, Texaco has agreed to negotiate, in consultation with Chevron, definitive agreements responsive to the regulatory requirements. The merger agreement further provides that if an agreement of this kind is required and Texaco has not entered into such an agreement 15 days before the date of the Texaco stockholders' meeting for the merger, Mr. O'Reilly and Mr. Tilton will meet to discuss the status of such efforts by Texaco. Chevron and Texaco have agreed to place Texaco's alliance interests in a liquidating trust if necessary to achieve any remaining conditions to closing. The merger agreement specifically provides that a disposition of Texaco's alliance interests in Equilon and Motiva under agreements contemplated above will not be deemed to have a material adverse effect on Texaco for purposes of determining whether conditions to closing have been satisfied. Conversely, the merger agreement also provides that any requirement imposed by a regulatory agency to sell, hold separate or limit in any material respect the operations of Chevron's refining and marketing business in the Western United States will be deemed to have a material adverse effect on Chevron for purposes of determining whether conditions to closing have been satisfied and would therefore give Chevron the option not to complete the merger. Chevron and Texaco do not expect that any regulatory agency will impose a requirement in connection with the merger that Chevron sell, hold separate or limit in any material respect Chevron's Western U.S. refining and marketing business. Employee Benefits Matters. The merger agreement provides that Chevron will cause the surviving corporation to honor in accordance with their terms all obligations under Texaco's executive benefit arrangements and under all other existing Texaco employee and retiree arrangements and plans to the extent entitlements or rights exist under those arrangements or plans as of the effective time of the merger. Chevron and Texaco have agreed that the merger will constitute a change in control under Texaco's employment arrangements and benefit plans in accordance with the terms of those arrangements and plans. Chevron has also agreed, following the closing, to provide Texaco employees who were employed by Texaco or its subsidiaries at the closing and who continue as employees of ChevronTexaco or its subsidiaries, for so long as they remain so employed, employee benefits, under benefit plans and arrangements as provided to those employees immediately prior to the closing, or under benefit plans and arrangements maintained by Chevron providing coverage and benefits which, in the aggregate, are no less favorable than those provided to employees of Chevron in positions comparable to the positions held by the continuing Texaco employees. In addition, Chevron has agreed that, following the closing, ChevronTexaco will continue to provide former employees of Texaco and its subsidiaries (and to Texaco employees whose employment terminates prior to the closing) post-retirement benefits, other than pensions, under benefit plans and arrangements applicable to those retirees as in effect as of October 15, 2000, or under benefit plans or arrangements maintained by Chevron or its subsidiaries providing post-retirement coverage and benefits, other than pensions, which, in the aggregate, are no less favorable than those provided to former employees of Chevron. Please see "Interests of Directors and Officers in the Merger," beginning on page 47, for additional information on employee benefits matters covered in the merger agreement. -68-

Indemnification and Insurance of Texaco Directors and Officers. Chevron has agreed that: o it will indemnify former Texaco directors, officers and employees for liabilities from their acts or omissions in those capacities occurring prior to closing to the extent provided under Texaco's certificate of incorporation and by-laws as in effect on October 15, 2000; o it will cause Texaco to honor all indemnification agreements with its former directors, officers and employees in effect as of October 15, 2000; and o for six years after the merger becomes effective, it will provide officers' and directors' liability insurance covering acts or omissions occurring prior to the effective time of the merger by each person currently covered by Texaco's officers' and directors' liability insurance policy. This ChevronTexaco policy must be no less favorable than the Texaco policy in effect on October 15, 2000, except that ChevronTexaco will be obligated to pay only up to 300 percent of the annual premium paid by Texaco for such insurance as of October 15, 2000. Chevron may provide this coverage through a policy underwritten by a wholly-owned Chevron subsidiary. Other Covenants. The merger agreement contains additional mutual covenants of the parties, including an agreement not to jeopardize the intended tax or accounting treatment of the merger. Representations and Warranties The merger agreement contains substantially reciprocal representations and warranties made between Chevron and Texaco. The most significant of these relate to: o corporate authorization to enter into the transactions contemplated by the merger agreement; o the stockholder votes and governmental approvals required in connection with the contemplated transactions; o absence of any breach of organizational documents, law or various material agreements as a result of the contemplated transactions; o capitalization; o ownership of subsidiaries; o filings with the SEC; o financial statements; o accuracy of information provided for inclusion in this joint proxy statement/prospectus; o absence of material changes since a specified balance sheet date; o absence of undisclosed material liabilities; o litigation; o tax matters; o employee benefits matters; o compliance with laws; o finders' or advisors' fees; o environmental matters; o the receipt of accountants' letters regarding accounting treatment of the merger; o absence of circumstances inconsistent with the intended accounting treatment of the merger; o inapplicability of the Delaware anti-takeover statute; and o amendments to stockholder rights plans to render them inapplicable to the merger and the stock options. -69-

In addition, Texaco represents and warrants to the best of its knowledge and belief to Chevron as to the audited consolidated financial statements of each of Equilon Enterprises LLC and Motiva Enterprises LLC. The representations and warranties in the merger agreement do not survive the closing or termination of the merger agreement. Conditions to the Completion of the Merger Mutual Closing Conditions. The obligations of Chevron and Texaco to complete the merger are subject to the satisfaction or, to the extent legally permissible, waiver of the following conditions: o approval by the Chevron stockholders of the common stock issuance in the merger; o approval by the Texaco stockholders of the merger agreement and the merger; o expiration of the HSR Act waiting period; o approval by the European Commission of the contemplated transactions; o absence of any legal prohibition on completion of the merger or any legal requirement that, if not complied with, will be reasonably likely to have a material adverse effect on ChevronTexaco following the merger; o Chevron's registration statement on Form S-4, which includes this proxy statement/prospectus, being effective and not subject to any stop order by the SEC; o approval for the listing on the NYSE of the shares of Chevron common stock to be issued in the merger; o receipt of a letter from the independent accountants of Chevron reconfirming their concurrence with Chevron's management that "pooling-of-interests" accounting treatment for the merger is appropriate; o receipt of a letter from the independent public accountant of Texaco reconfirming their concurrence with Texaco's management that Texaco is eligible to participate in a "pooling-of-interests" transaction; o absence of any condition to approval of the merger by the Federal Trade Commission or the Department of Justice that would be reasonably likely to result in a material adverse effect on ChevronTexaco following the merger; o absence of any proceeding seeking to limit Chevron's ownership of Texaco or to compel divestiture of assets, in either case that would be reasonably likely to result in a material adverse effect on ChevronTexaco following the merger; o absence of any statute, rule or other governmental order applicable to the merger that would be reasonably likely to result in a material adverse effect on ChevronTexaco following the merger; o receipt of all material regulatory approvals for the merger on terms that are not reasonably likely to result in a material adverse effect on ChevronTexaco following the merger; o performance in all material respects by the other party of the obligations required to be performed by it at or prior to closing; o accuracy as of closing of the representations and warranties made by the other party to the extent specified in the merger agreement; o receipt of opinions of Chevron's and Texaco's counsel that the merger will qualify as a tax-free reorganization; and o absence of a material adverse effect or any reasonable likelihood of a material adverse effect on Chevron or Texaco during the period from October 15, 2000 until closing. -70-

For purposes of the applicable closing conditions listed above, any requirement imposed by a regulatory agency to sell, hold separate, or limit in any material respect the operations of Chevron's refining and marketing business in the Western United States will be deemed to have a material adverse effect on ChevronTexaco following the merger. Satisfaction of Closing Conditions. On March 1, 2001, the European Commission announced that it had approved the merger. The other conditions listed above have not been satisfied and may not be satisfied until immediately prior to the closing. Termination of the Merger Agreement Right to Terminate. The merger agreement may be terminated at any time prior to the closing in any of the following ways: (a) by mutual written consent of Chevron and Texaco. (b) by either Chevron or Texaco if: o the merger has not been completed by October 15, 2001. However, that date becomes April 15, 2002 if the reason for not closing by October 15, 2001 is that the regulatory conditions specified in the merger agreement have not been satisfied by that date; o Chevron or Texaco stockholders fail to give the necessary approvals; or o there is a permanent legal prohibition to closing the merger. (c) by Chevron if the Texaco board fails to recommend the merger or withdraws or modifies in a manner adverse to Chevron its approval or recommendation of the merger, breaches its agreement to call the Texaco meeting or recommends a superior offer. (d) by Texaco if the Chevron board fails to recommend the merger or withdraws or modifies in a manner adverse to Texaco its approval or recommendation of the common stock issuance or name change, breaches its agreement to call the Chevron meeting or recommends a superior offer. (e) by Chevron or Texaco if the other party has breached its representations, warranties, covenants or obligations under the merger agreement, which breach would result in the failure to satisfy related closing conditions and such breach shall be incapable of being cured, or, if capable of being cured, shall not have been cured within 30 days after written notice thereof was received. Neither Chevron nor Texaco can terminate the merger agreement for the reasons described in the first bullet under paragraph (b) above if its failure to fulfill in any material respect its obligations under the merger agreement has resulted in the failure to complete the merger. If the merger agreement is validly terminated, the agreement will become void without any liability on the part of any party unless such party is in willful breach. However, the provisions of the merger agreement relating to expenses and termination fees, as well as the confidentiality agreement and the stock option agreements entered into between Chevron and Texaco, will continue in effect notwithstanding termination of the merger agreement. Termination Fees Payable by Texaco. Texaco has agreed to pay Chevron a cash amount equal to $500 million in any of the following circumstances: o Chevron terminates the merger agreement as described in paragraph (c) under "Right to Terminate" above; -71-

o either Chevron or Texaco terminates the merger agreement if Texaco stockholders fail to give the necessary approval at a duly held meeting and prior to such meeting an alternative offer was made to Texaco or its stockholders; or o a third party makes an alternative offer to Texaco or its stockholders and thereafter the merger agreement is terminated as described in the first bullet of paragraph (b) above. Texaco has agreed to pay Chevron an additional termination fee of $500 million in cash if an alternative transaction is agreed to or consummated within 12 months after the termination of the merger agreement. Termination Fees Payable by Chevron. Chevron has agreed to pay Texaco a cash amount equal to $500 million in any of the following circumstances: o Texaco terminates the merger agreement as described in paragraph (d) under "Right to Terminate" above; o either Texaco or Chevron terminates the merger agreement if Chevron stockholders fail to approve the common stock issuance at a duly held meeting and prior to such meeting an alternative offer was made to Chevron or its stockholders; or o a third party makes an alternative offer to Chevron or its stockholders and thereafter the merger agreement is terminated as described in the first bullet of paragraph (b) above. Chevron has agreed to pay Texaco an additional termination fee of $500 million in cash if an alternative transaction is agreed to or consummated within 12 months after the termination of the merger agreement. Expenses Except as described above, all costs and expenses incurred in connection with the merger agreement and related transactions will be paid by the party incurring such costs or expenses. We estimate that merger-related fees and expenses, consisting primarily of SEC filing fees, fees and expenses of investment bankers, attorneys and accountants, and financial printing and other related charges, will total approximately $125 million assuming the merger is completed. Amendments; Waivers Any provision of the merger agreement may be amended or waived prior to closing if the amendment or waiver is in writing and signed, in the case of an amendment, by Texaco, Chevron and the merger subsidiary or, in the case of a waiver, by the party against whom the waiver is to be effective. After the approval of the merger agreement by the stockholders of Texaco, no amendment or waiver shall change the amount or kind of merger consideration or any term of Chevron's or Texaco's certificate of incorporation or otherwise adversely affect the Texaco stockholders without the further approval of such stockholders. Stock Option Agreements The following summary of the stock option agreements is qualified by reference to the complete text of the two stock option agreements, which are incorporated by reference into this proxy statement/prospectus and attached as Annex B and Annex C. General. At the same time that Chevron and Texaco entered into the merger agreement, they also entered into two separate stock option agreements. Under the stock option agreements, Texaco granted Chevron an irrevocable option to purchase up to 107,000,000 shares of Texaco common stock at a price per share of $53.71, and Chevron granted Texaco an irrevocable option to purchase up to 127,000,000 shares of Chevron common stock at a price per share of $85.96. The exercise price of each option was calculated based on the average of the closing prices of the stock subject to the option for the ten trading days prior to the announcement of the merger agreement. The options are exercisable in the circumstances described below. -72-

Exercise of the Stock Option. Chevron can exercise the option in whole or in part at any time after the occurrence of any event, which we call a trigger event in this section, entitling Chevron to receive the cash termination fee payable by Texaco under the merger agreement (see "--Termination of the Merger Agreement--Termination Fees Payable by Texaco" on pages 71 and 72) and prior to termination of the option. Texaco can exercise the option in whole or in part at any time after the occurrence of any event, which we call a trigger event in this section, entitling Texaco to receive the cash termination fee payable by Chevron under the merger agreement (see "--Termination of the Merger Agreement--Termination Fees Payable by Chevron" on page 72) and prior to termination of the option. The option terminates upon the earliest to occur of o the closing of the merger; o 90 days after Chevron or Texaco, as applicable, has paid the cash termination fee in full; or o one day after termination of the merger agreement so long as no trigger event has occurred or could still occur. The exercise price and number of option shares are also subject to anti-dilution and other adjustments specified in the stock option agreements. Any purchase of option shares is subject to specified closing conditions, including receipt of applicable regulatory approvals. The closing of any purchase of option shares may be postponed for up to nine months beyond the termination of the option pending satisfaction of the conditions to purchase. Cash Election. The stock option agreements further provide that, so long as the option is exercisable, Chevron or Texaco, as applicable, may, instead of exercising the option, elect to require the other party to pay, in exchange for the cancellation of the relevant portion of the option, an amount in cash equal to the "spread" (as defined below) multiplied by the number of option shares as to which such a cash election is made. "Spread" means the excess, if any, over the exercise price of the higher of o the highest price per share of Texaco common stock or Chevron common stock, as applicable, paid or proposed to be paid by any third party under an alternative acquisition proposal (which we call the alternative exercise price) and o the average of the closing price of shares of Texaco common stock or Chevron common stock, as applicable, on the NYSE, at the end of the regular session, as reported on the Consolidated Tape, Network A for the five consecutive trading days ending on the trading date immediately preceding the date on which Chevron or Texaco notifies the other party that it intends to make a cash election (which we call the average market price). At any time following exercise of either of the stock options, the company against which the option was exercised has the right, within 5 business days after written notice to the other, to purchase for cash all of the option shares at a purchase price per share equal to the higher of the alternative exercise price or the average market price. Limitation on Total Profit. The stock option agreements provide that, notwithstanding any other provision of the stock option agreements or the merger agreement, neither company's total profit (as defined below) will exceed $1.1 billion in the aggregate. If either party's total profit otherwise would exceed such amount that party, at its sole election, may pay cash to the other, deliver to the other for cancellation option shares previously acquired by it or any combination thereof, so that its actually realized total profit does not exceed $1.1 billion after taking into account the foregoing actions. For purposes of the stock option agreements, "total profit" means the aggregate amount, before taxes, of the following: (1) (x) the cash amount actually received by a party in payment by the other party of the termination fee under the merger agreement, less (y) any repayment by that party as described in the preceding paragraph; (2) the net cash amounts received by that party upon the sale of option shares (or of any other securities into or for which such option shares are converted or exchanged), less its purchase price for such option shares (or other securities), -73-

plus (3) the aggregate amount received by that party upon exercise of the cash election described under "Cash Election" above. The stock option agreements also provide that, notwithstanding any other provision of the agreements, the option may not be exercised for a number of option shares that would, as of the date of exercise, result in a notional total profit (as described below) exceeding $1.1 billion. For purposes of the stock option agreements, the "notional total profit" with respect to the option shares for which Chevron or Texaco may propose to exercise the option means the total profit determined as of the date a party notifies the other party of its intent to exercise the option and assuming that the applicable option shares, together with all other option shares previously acquired upon exercise of the option and held by the exercising party or its affiliates as of such date, were sold for cash at the NYSE closing price on the preceding trading day. Listing and Registration Rights. Each of Chevron and Texaco has agreed to list the option shares on the NYSE and to grant the other customary rights to require registration of the option shares under the securities laws. Effect of Options. The options are intended to make it more likely that the merger will be completed on the agreed terms and to compensate Chevron or Texaco for its efforts and costs in case the merger is not completed under circumstances generally involving a third party proposal for a business combination with the other party. Among other effects, the options could also prevent an alternative business combination with either party from being accounted for as a "pooling-of-interests." The options may therefore discourage proposals for alternative business combinations with Texaco and Chevron even if a third party were prepared to offer Texaco stockholders consideration with a higher market value than the value of the ChevronTexaco stock to be exchanged for Texaco stock in the merger. -74-

COMPARISON OF STOCKHOLDER RIGHTS The rights of Texaco stockholders under Delaware law, the Texaco certificate of incorporation and the Texaco by-laws prior to the merger are substantially the same as the rights ChevronTexaco stockholders will have following the merger under Delaware law, the ChevronTexaco restated certificate of incorporation and the ChevronTexaco by-laws, with principal exceptions summarized in the chart below. The certificate of incorporation and by-laws of ChevronTexaco will be identical in all respects to those of Chevron after giving effect to the name change. Copies of the Texaco certificate of incorporation, the Texaco by-laws, the Chevron restated certificate of incorporation and the Chevron by-laws are incorporated by reference and will be sent to holders of shares of Texaco common stock upon request. See "Where You Can Find More Information" on page 85.

DESCRIPTION OF CHEVRON CAPITAL STOCK The following description highlights material terms of the capital stock of Chevron. This description is qualified in its entirety by reference to the restated certificate of incorporation and by-laws of Chevron which are incorporated herein by reference. See "Where You Can Find More Information" on page 85 for more information about the documents incorporated by reference in this joint proxy statement/prospectus. The authorized capital stock of Chevron currently consists of two billion shares of common stock, par value $0.75 per share, and one hundred million shares of preferred stock, par value $1.00 per share. At December 31, 2000, there were outstanding 641,059,971 shares of Chevron common stock, with an additional 71,427,097 issued and held in treasury. There are no shares of Chevron preferred stock outstanding. Chevron Common Stock The holders of Chevron common stock are entitled to receive such dividends or distributions as are lawfully declared on Chevron common stock, to have notice of any authorized meeting of stockholders, and to one vote for each share of Chevron common stock on all matters which are properly submitted to a vote of Chevron stockholders. As a Delaware corporation, Chevron is subject to statutory limitations on the declaration and payment of dividends. In the event of a liquidation, dissolution or winding up of Chevron, holders of Chevron common stock have the right to a ratable portion of assets remaining after satisfaction in full of the prior rights of creditors, including holders of Chevron's indebtedness, all liabilities and the aggregate liquidation preferences of any outstanding shares of Chevron preferred stock. The holders of Chevron common stock have no conversion, redemption, preemptive or cumulative voting rights. All outstanding shares of Chevron common stock are, and the shares of Chevron common stock to be issued in the merger will be, validly issued, fully paid and non-assessable. At December 31, 2000, there were 108,604 holders of Chevron common stock. Chevron Preferred Stock Chevron's restated certificate of incorporation expressly authorizes the board of directors to issue preferred stock in one or more series, to establish the number of shares in any series and to set the designation and preferences of any series and the powers, rights, qualifications, limitations or restrictions on each series of preferred stock. In connection with the adoption of the Chevron stockholder rights plan, the Chevron board has designated 5,000,000 shares of preferred stock as series A participating preferred stock, $1.00 par value per share (the "Chevron participating preferred stock"). Upon issuance, each share of Chevron participating preferred stock is entitled to a preferential quarterly dividend in an amount equal to 1,000 times the dividend declared on each share of Chevron common stock, but in no event less than $25. In the event of liquidation, the holders of shares of Chevron participating preferred stock will receive a preferred liquidation payment equal to the greater of $1000 or 1000 times the payment made per each share of Chevron common stock. Each share of Chevron participating preferred stock is entitled to 1,000 votes, voting together with the shares of Chevron common stock. In the event of any merger, consolidation or other transaction in which shares of Chevron common stock are exchanged, each share of Chevron participating preferred stock will be entitled to receive 1,000 times the amount and type of consideration received per share of Chevron common stock. The rights of the Chevron participating preferred stock as to dividends, liquidation and voting, and in the event of mergers and consolidations, are protected by customary anti-dilution provisions. The Chevron participating preferred stock ranks junior to all other series of Chevron preferred stock as to the payment of dividends and the distribution of assets, unless the terms of any such series provide otherwise. At December 31, 2000, there were no shares of Chevron participating preferred stock outstanding. -82-

Stock Exchange Listing; Delisting and Deregistration of Texaco Common Stock It is a condition to the merger that the shares of ChevronTexaco common stock issuable in the merger be approved for listing on the NYSE at or prior to the closing, subject to official notice of issuance. If the merger is completed, Texaco common stock will cease to be listed.

At December 31, 2000, there were outstanding 550,161,286 shares of Texaco common stock, no shares of Series D Junior Participating Preferred Stock and 1,200 shares of Market Auction Preferred Stock. All shares of Market Auction Preferred Stock will be redeemed prior to the merger. The holders of Texaco common stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders. Subject to preferences that may be applicable to any outstanding Texaco preferred stock, holders of Texaco common stock are entitled to receive ratably such dividends as may be declared by the Texaco board out of funds legally available therefor. In the event of a liquidation or dissolution of Texaco, holders of Texaco Common Stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preference of any outstanding Texaco preferred stock. Holders of Texaco common stock have no preemptive rights, no redemption rights and no rights to convert their Texaco common stock into any other securities. Under Texaco's stockholder rights plan, rights to purchase Texaco's Series D Junior Participating Preferred Stock are attached to shares of common stock. For a description of the rights, see Texaco's definitive proxy statement on Schedule 14 filed with the SEC on March 17, 1998 and Amendment No. 1 to its Form 8-A filed with the SEC on October 25, 2000.

SECTION 1.2 Conversion of Shares. -------------------- (a) At the Effective Time by virtue of the Merger and without any action on the part of the holder thereof: (i) each share of the Company Common Stock held by the Company as treasury stock or owned by Parent or any subsidiary of Parent or the Company (excluding shares, if any, held in any "Rabbi trust" identified on Section 3.14 of the Company Disclosure Schedule, which may be accounted for as treasury stock ("Rabbi Trust Shares")) immediately prior to the Effective Time (together with the associated Company Right (as defined in Section 3.5), if any) shall be canceled, and no payment shall be made with respect thereto; A-2

(ii) each share of common stock of Merger Subsidiary outstanding immediately prior to the Effective Time shall be converted into and become one share of common stock of the Surviving Corporation with the same rights, powers and privileges as the shares so converted and shall constitute the only outstanding shares of capital stock of the Surviving Corporation; and (iii) each share of Company Common Stock (including each Rabbi Trust Share) (together with the associated Company Right) outstanding immediately prior to the Effective Time shall, except as otherwise provided in Section 1.2(a)(i), be converted into the right to receive 0.77 of a share of Parent Common Stock (the "Exchange Ratio"), including the corresponding fraction of a right to purchase shares of Series A Participating Preferred Stock of Parent (the "Parent Rights") in accordance with the Rights Agreement (the "Parent Rights Agreement") dated as of November 23, 1998 between Parent and ChaseMellon Shareholder Services, L.L.C., as Rights Agent. References herein to shares of Parent Common Stock issuable pursuant to the Merger shall also be deemed to include the associated Parent Rights. (b) All Parent Common Stock issued as provided in this Section 1.2 shall be of the same class and shall have the same terms as the currently outstanding Parent Common Stock. The shares of Parent Common Stock to be received as consideration pursuant to the Merger with respect to shares of Company Common Stock (together with cash in lieu of fractional shares of Parent Common Stock as specified below) are referred to herein as the "Merger Consideration." (c) From and after the Effective Time, all shares of Company Common Stock (together with the associated Company Rights) converted in accordance with Section 1.2(a)(iii) shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration and any dividends payable pursuant to Section 1.3(f). From and after the Effective Time, all certificates representing the common stock of Merger Subsidiary shall be deemed for all purposes to represent the number of shares of common stock of the Surviving Corporation into which they were converted in accordance with Section 1.2(a)(ii). SECTION 1.3 Surrender and Payment. --------------------- (a) Prior to the Effective Time, Parent shall appoint ChaseMellon Shareholder Services, L.L.C. or such other exchange agent reasonably acceptable to the Company (the "Exchange Agent") for the purpose of exchanging certificates representing shares of Company Common Stock ("Certificates") for the Merger Consideration. Parent will make available to the Exchange Agent, as needed, the Merger Consideration to be delivered in respect of the shares of Company Common Stock. Promptly after the Effective Time, Parent will send, or will cause the Exchange Agent to send, to each holder of record of shares of Company Common Stock as of the Effective Time, a letter of transmittal for use in such exchange (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates to the Exchange Agent) in such form as the Company and Parent may reasonably A-3

agree, for use in effecting delivery of shares of Company Common Stock to the Exchange Agent. (b) Each holder of shares of Company Common Stock that have been converted into a right to receive the Merger Consideration, upon surrender to the Exchange Agent of a Certificate, together with a properly completed letter of transmittal, will be entitled to receive the Merger Consideration in respect of the shares of Company Common Stock represented by such Certificate. Until so surrendered, each such Certificate shall, after the Effective Time, represent for all purposes only the right to receive such Merger Consideration. (c) If any portion of the Merger Consideration is to be registered in the name of a Person other than the Person in whose name the applicable surrendered Certificate is registered, it shall be a condition to the registration thereof that the surrendered Certificate shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any transfer or other taxes required as a result of such registration in the name of a Person other than the registered holder of such Certificate or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable. For purposes of this Agreement, "Person" means an individual, a corporation, a limited liability company, a partnership, an association, a trust or any other entity or organization, including a government or political subdivision or any agency or instrumentality thereof. (d) After the Effective Time, there shall be no further registration of transfers of shares of Company Common Stock. If, after the Effective Time, Certificates are presented to the Exchange Agent, the Surviving Corporation or the Parent, they shall be canceled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in this Article 1. (e) Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Section 1.3(a) that remains unclaimed by the holders of shares of Company Common Stock one year after the Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged his shares of Company Common Stock for the Merger Consideration in accordance with this Section 1.3 prior to that time shall thereafter look only to Parent for delivery of the Merger Consideration in respect of such holder's shares. Notwithstanding the foregoing, Parent shall not be liable to any holder of shares for any Merger Consideration delivered to a public official pursuant to applicable abandoned property laws. Any Merger Consideration remaining unclaimed by holders of shares of Company Common Stock three years after the Effective Time (or such earlier date immediately prior to such time as such amounts would otherwise escheat to or become property of any governmental entity) shall, to the extent permitted by applicable law, become the property of Parent free and clear of any claims or interest of any Person previously entitled thereto. (f) No dividends or other distributions with respect to shares of Parent Common Stock issued in the Merger shall be paid to the holder of any unsurrendered Certificates until such Certificates are surrendered as provided in this Section 1.3. Subject to the effect of applicable laws, following such surrender, there shall be paid, without interest, to the record A-4

holder of the shares of Parent Common Stock issued in exchange therefor (i) at the time of such surrender, all dividends and other distributions payable in respect of such shares of Parent Common Stock with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such shares of Parent Common Stock with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of dividends or other distributions in respect of shares of Parent Common Stock, all shares of Parent Common Stock to be issued pursuant to the Merger (but not options therefor described in Section 1.4 unless actually exercised at the Effective Time) shall be entitled to dividends pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time. SECTION 1.4 Stock Options and Equity Awards. ------------------------------- (a) The Board of Directors of the Company shall take such action as is necessary so that at the Effective Time, each outstanding option to purchase shares of Company Common Stock (a "Company Stock Option") granted under the Company's plans or agreements identified in Company Disclosure Schedule (defined in the introductory clause to Article 3) 1.4 as being the only compensation or benefit plans or agreements pursuant to which shares of Company Common Stock may be issued (collectively, the "Company Stock Option Plans"), whether vested or not vested, shall cease to represent a right to acquire shares of Company Common Stock and shall thereafter constitute an option to acquire, on the same terms and conditions as were applicable under such Company Stock Option (including without limitation the stock option restoration feature applicable thereto) pursuant to the relevant Company Stock Option Plan under which it was issued and the agreement evidencing the grant thereof prior to the Effective Time, the number (rounded to the nearest whole number) of shares of Parent Common Stock determined by multiplying (x) the number of shares of Company Common Stock subject to such Company Stock Option immediately prior to the Effective Time by (y) the Exchange Ratio. The exercise price per share of Parent Common Stock subject to any such Company Stock Option at and after the Effective Time shall be an amount (rounded to the nearest one-hundredth of a cent) equal to (x) the exercise price per share of Company Common Stock subject to such Company Stock Option prior to the Effective Time, divided by (y) the Exchange Ratio. Notwithstanding any other provisions of this Section 1.4(a), if use of the above methods would disqualify the Merger as a "pooling of interests" for financial accounting purposes, then such methods will be adjusted to the extent necessary to preserve such accounting treatment. In addition, prior to the Effective Time, the Company will make any amendments to the terms of such Company Stock Option Plans that are necessary to give effect to the transactions contemplated by this Section 1.4. The Company represents and warrants that no consents are or will be necessary to give effect to the transactions contemplated by this Section 1.4. (b) Parent shall take all corporate action necessary to assume as of the Effective Time the Company's obligations under the Company Stock Options and reserve for issuance a sufficient number of shares of Parent Common Stock for delivery pursuant to the terms set forth in this Section 1.4. A-5

(c) At the Effective Time, each award or account (including restricted stock, stock equivalents and stock units, but excluding Company Stock Options) outstanding as of the Effective Time ("Company Award") that has been established, made or granted under any employee incentive or benefit plans, programs or arrangements and non-employee director plans maintained by the Company on or prior to the date hereof that provide for grants of equity-based awards or equity-based accounts and which are identified in Company Schedule 1.4 shall to the extent practicable be amended or converted into a similar instrument of Parent, in each case with such adjustments to the terms and conditions of such Company Awards as are appropriate to preserve the value inherent in such Company Awards with no detrimental effects on the holders thereof. The other terms and conditions of each Company Award, and the plans or agreements under which they were issued, shall continue to apply in accordance with their terms and conditions, including any provisions for acceleration (as such terms and conditions have been interpreted and applied by the Company in accordance with its past practice), but with such adjustments, if any, as may be necessary or appropriate in light of the transactions contemplated hereby and which do not materially affect the intended value of such awards, in each case to the extent consistent with Section 7.4. The Company represents and warrants that (i) there are as of the date hereof no Company Awards or Company Stock Options other than those reflected in Section 3.5 and (ii) all employee incentive or benefit plans, programs or arrangements and non-employee director plans under which any Company Award has been established, made or granted and all Company Stock Option Plans are disclosed in Company Disclosure Schedule 1.4. (d) As soon as practicable after the Effective Time, Parent shall file with the Commission a registration statement on an appropriate form or a post-effective amendment to a previously filed registration statement under the Securities Act of 1933, as amended (the "Securities Act"), with respect to the Parent Common Stock subject to options and other equity based awards described in this Section 1.4, and shall use its reasonable best efforts to maintain the current status of the prospectus contained therein, as well as comply with any applicable state securities or "blue sky" laws, for so long as such options or other equity based awards remain outstanding. SECTION 1.5 Adjustments. If at any time during the period ----------- between the date of this Agreement and the Effective Time, any change in the outstanding shares of capital stock of Parent or the Company shall occur by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend thereon with a record date during such period, the Merger Consideration shall be appropriately adjusted to provide the holders of shares of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event. SECTION 1.6 Fractional Shares. ----------------- (a) No fractional shares of Parent Common Stock shall be issued in the Merger, but in lieu thereof each holder of shares of Company Common Stock otherwise entitled to a fractional share of Parent Common Stock will be entitled to receive, from the Exchange Agent in accordance with the provisions of this Section 1.6, a cash payment in lieu of such fractional shares of Parent Common Stock representing such holder's proportionate interest, if any, in the A-6

proceeds from the sale by the Exchange Agent in one or more transactions of shares of Parent Common Stock equal to the excess of (x) the aggregate number of shares of Parent Common Stock to be delivered to the Exchange Agent by Parent pursuant to Section 1.3(a) over (y) the aggregate number of whole shares of Parent Common Stock to be distributed to the holders of Certificates pursuant to Section 1.3(b) (such excess being herein called the "Excess Shares"). The parties acknowledge that payment of the cash consideration in lieu of issuing fractional shares was not separately bargained for consideration but merely represents a mechanical rounding off for purposes of simplifying the corporate and accounting problems that would otherwise be caused by the issuance of fractional shares. As soon as practicable after the Effective Time, the Exchange Agent, as agent for the holders of the certificates representing shares of Company Common Stock, shall sell the Excess Shares at then prevailing prices on the New York Stock Exchange (the "NYSE") in the manner provided in the following paragraph. (b) The sale of the Excess Shares by the Exchange Agent, as agent for the holders that would otherwise receive fractional shares, shall be executed on the NYSE through one or more member firms of the NYSE and shall be executed in round lots to the extent practicable. The compensation payable to the Exchange Agent and the expenses incurred by the Exchange Agent, in each case, in connection with such sale or sales of the Excess Shares, and all related commissions, transfer taxes and other out-of-pocket transaction costs, will be paid by the Surviving Corporation out of its own funds and will not be paid directly or indirectly by Parent. Until the proceeds of such sale or sales have been distributed to the holders of shares of Company Common Stock, the Exchange Agent shall hold such proceeds in trust for the holders of shares of Company Common Stock (the "Common Shares Trust"). The Exchange Agent shall determine the portion of the Common Shares Trust to which each holder of shares of Company Common Stock shall be entitled, if any, by multiplying the amount of the aggregate proceeds comprising the Common Shares Trust by a fraction, the numerator of which is the amount of the fractional share interest to which such holder of shares of Company Common Stock would otherwise be entitled and the denominator of which is the aggregate amount of fractional share interests to which all holders of shares of Company Common Stock would otherwise be entitled. (c) As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of shares of Company Common Stock in lieu of any fractional shares of Parent Common Stock, the Exchange Agent shall make available such amounts to such holders of shares of Company Common Stock without interest. SECTION 1.7 Withholding Rights. Each of the Surviving Corporation and ------------------ Parent shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article 1 such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign tax law. To the extent that amounts are so withheld by the Surviving Corporation or Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by the Surviving Corporation or Parent, as the case may be. A-7

SECTION 1.8 Lost Certificates. If any Certificate shall have been lost, ----------------- stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Surviving Corporation, the posting by such Person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration to be paid in respect of the shares of Company Common Stock represented by such Certificate as contemplated by this Article 1. SECTION 1.9 Shares Held by Company Affiliates. Anything to the contrary --------------------------------- herein notwithstanding, no shares of Parent Common Stock (or certificates therefor) shall be issued in exchange for any Certificate to any Person who may be an "affiliate" of the Company (identified pursuant to Section 7.8) until such Person shall have delivered to Parent duly executed letters as contemplated by Section 7.8. Such Person shall be subject to the restrictions described in such letters, and such shares (or certificates therefor) shall bear a legend describing such restrictions. SECTION 1.10 Appraisal Rights. In accordance with Section 262 of the ---------------- Delaware Law, no appraisal rights shall be available to holders of shares of Company Common Stock in connection with the Merger. ARTICLE 2 --------- CERTAIN GOVERNANCE MATTERS -------------------------- SECTION 2.1 Name; Trade Name. ---------------- (a) Parent shall take all such action as is necessary to change its name to "ChevronTexaco Corporation" effective as of the Effective Time, which action shall include, without limitation, seeking stockholder approval to amend Parent's Restated Certificate of Incorporation to effect such name change (the "Name Change Amendment") as provided in Section 6.4. Subject to Parent obtaining the necessary approval of its stockholders under Delaware Law for the Name Change Amendment, simultaneously with the filing of the certificate of merger contemplated by Section 1.1(b), Parent shall file a certificate of amendment to its Restated Certificate of Incorporation with the Secretary of State of the State of Delaware and make all other filings and records required by Delaware Law in connection with the amendment of the certificate of incorporation contemplated hereby. This amendment shall become effective at the Effective Time. (b) It is the intention of Parent that the marketing operations currently conducted by the Company and its Subsidiaries outside the United States will continue to be conducted under the "Texaco" trademark. SECTION 2.2 Parent Board of Directors. ------------------------- (a) At the Effective Time, the Board of Directors of Parent shall consist of fifteen A-8

(15) directors, of whom six (6) directors shall be persons who are directors of the Company designated prior to the Effective Time by the Company and reasonably acceptable to Parent (the "Company Board Designees"), and the remainder of whom shall be directors of Parent prior to the Effective Time. Prior to the Effective Time, the Board of Directors of Parent shall take all action necessary to increase the size of the Board of Directors of Parent as necessary and to elect the Company Board Designees to the Board of Directors of Parent, in each case as of the Effective Time. (b) The Board of Directors of Parent shall take all action necessary to cause Peter I. Bijur to be elected as Vice Chairman of the Board of Directors of Parent as of the Effective Time. (c) Parent shall cause, as of the Effective Time, each Committee of the Board of Directors of Parent to include at least one Company Board Designee. SECTION 2.3 Transition Committee. The parties agree to establish a -------------------- transition committee (the "Transition Committee") which will have a consultative role and which will be in effect from the date hereof until the earlier of the termination hereof and the Effective Time. The Transition Committee shall be comprised of Peter I. Bijur and David J. O'Reilly. The Transition Committee will be concerned with matters relating to planning the integration after the Effective Time of Parent and the Company, including organization and staffing. Notwithstanding anything in this Section 2.3, Parent shall not be deemed to control the business or operations of the Company and, likewise, the Company shall not be deemed to control the business or operations of Parent. The members of the Transition Committee may delegate specific tasks to others and otherwise will draw upon the resources of Parent and the Company as necessary or appropriate. SECTION 2.4 Certificate of Incorporation of the Surviving Corporation. The --------------------------------------------------------- certificate of incorporation of the Company in effect at the Effective Time shall be the certificate of incorporation of the Surviving Corporation until subsequently amended in accordance with applicable law. SECTION 2.5 By-laws of the Surviving Corporation. The by-laws of the ------------------------------------ Company in effect at the Effective Time shall be the by-laws of the Surviving Corporation until subsequently amended in accordance with applicable law. SECTION 2.6 Directors and Officers of the Surviving Corporation. From and --------------------------------------------------- after the Effective Time, until successors are duly elected or appointed and qualified in accordance with applicable law, (a) the directors of Merger Subsidiary at the Effective Time shall be the directors of the Surviving Corporation, and (b) the officers of the Company at the Effective Time shall be the officers of the Surviving Corporation. A-9

ARTICLE 3 --------- REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY -------------------------------------------------------- The Company represents and warrants to Parent that (except as set forth in the disclosure schedules delivered by the Company to Parent simultaneously with the execution of this Agreement (the "Company Disclosure Schedules")): SECTION 3.1 Corporate Existence and Power. The Company is a corporation ----------------------------- duly incorporated, validly existing and in good standing under the laws of the State of Delaware, and has all corporate powers and all governmental licenses, authorizations, consents and approvals required to carry on its business as now conducted, except for those the absence of which would not, individually or in the aggregate, have, or be reasonably likely to have, a Material Adverse Effect on the Company. The Company is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the character of the property owned or leased by it or the nature of its activities makes such qualification necessary, except for those jurisdictions where the failure to be so qualified would not, individually or in the aggregate, have, or be reasonably likely to have, a Material Adverse Effect on the Company. For purposes of this Agreement, a "Material Adverse Effect" with respect to any Person means a material adverse effect on the financial condition, business, liabilities, properties, assets or results of operations of such Person and its Subsidiaries, taken as a whole, except, to the extent resulting from (x) any changes in general United States or global economic conditions, (y) any changes affecting the oil and gas industry in general (including changes to commodity prices) except, other than where referring to a Material Adverse Effect on Parent after the Effective Time, to the extent that the changes disproportionately affect Parent or the Company, as applicable, compared to the manner in which the changes affect the other party or (z) any disposition of the Alliance Interests (as defined in Section 7.1) in accordance with the terms of Section 7.1. The Company has heretofore delivered to Parent true and complete copies of the Company's certificate of incorporation and by-laws as currently in effect. SECTION 3.2 Corporate Authorization. ----------------------- (a) The execution, delivery and performance by the Company of this Agreement and the Option Agreements and the consummation by the Company of the transactions contemplated hereby and thereby are within the Company's corporate powers and, except for any required approval by the Company's stockholders (the "Company Stockholder Approval") in connection with the consummation of the Merger, have been duly authorized by all necessary corporate action. The affirmative vote of holders of a majority of the outstanding shares of Company Common Stock in favor of the approval and adoption of this Agreement and the Merger is the only vote of the holders of any of the Company's capital stock necessary in connection with consummation of the Merger. Assuming due authorization, execution and delivery of this Agreement and the Option Agreements by Parent and/or Merger Subsidiary, as applicable, each of this Agreement and each Option Agreement constitutes a valid and binding agreement of the Company enforceable against the Company in accordance with its terms, subject to bankruptcy, A-10

insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights, and to general equity principles. (b) The Company's Board of Directors, at a meeting duly called and held on or prior to the date hereof, has (i) determined that this Agreement and the Option Agreements and the transactions contemplated hereby and thereby (including the Merger) are advisable, fair to and in the best interests of the Company's stockholders, (ii) approved and adopted this Agreement and the Option Agreements and the transactions contemplated hereby and thereby (including the Merger), and (iii) resolved (subject to Section 5.2) to recommend the approval and adoption of this Agreement and the Merger by its stockholders.

SECTION 3.4 Non-Contravention. The execution, delivery and performance by ----------------- the Company of this Agreement and the Option Agreements and the consummation by the Company of the transactions contemplated hereby and thereby do not and will not, assuming compliance with the matters referred to in Sections 3.2 and 3.3, (a) contravene or conflict with the certificate of incorporation or by-laws of the Company, (b) contravene or conflict with or constitute a violation of any provision of any law, regulation, judgment, injunction, order or decree binding upon or applicable to the Company or any of its Subsidiaries, (c) constitute a default under or give rise to a right of termination, cancellation or acceleration of any right or obligation of the Company or any of its Subsidiaries or to a loss of any benefit to which the Company or any of its Subsidiaries is entitled under any provision of any agreement, contract or other instrument binding upon the Company or any of its Subsidiaries or any license, franchise, permit or other similar authorization held by the Company or any of its Subsidiaries, or (d) result in the creation or imposition of any Lien on any asset of the Company or any of its Subsidiaries, except for such contraventions, conflicts or violations referred to in clause (b) or defaults, rights of termination, cancellation or acceleration, or losses or Liens referred to in clause (c) or (d) that would not, individually or in the aggregate, have, or be reasonably likely to have, a Material Adverse Effect on the Company. For purposes of this Agreement, "Lien" means, with respect to any asset, any mortgage, lien, pledge, charge, security interest or encumbrance of any kind in respect of such A-11

asset other than any such mortgage, lien, pledge, charge, security interest or encumbrance (i) for Taxes (as defined in Section 3.13) not yet due or being contested in good faith (and for which adequate accruals or reserves have been established on the Parent Balance Sheet or the Company Balance Sheet, as the case may be) or (ii) which is a carriers', warehousemen's, mechanics', materialmen's, repairmen's or other like lien arising in the ordinary course of business. Neither the Company nor any Subsidiary of the Company, nor to the knowledge of the Company, neither Joint Venture (as defined in Section 3.23 herein) nor any of its Subsidiaries, is a party to any agreement that expressly limits the ability of the Company or any Subsidiary of the Company, or would limit Parent or any Subsidiary of Parent after the Effective Time, to compete in or conduct any line of business or compete with any Person or in any geographic area or during any period of time except to the extent that any such limitation, individually or in the aggregate, would not have, or be reasonably likely to have, a Material Adverse Effect on the Company. SECTION 3.5 Capitalization. The authorized capital stock of the Company -------------- consists of 850,000,000 shares of Company Common Stock and 30,000,000 shares of preferred stock, par value $1.00 per share (of which 3,000,000 are designated Series D Junior Participating Preferred Stock, 300 are designated Market Auction Preferred Shares, Series G-1 through G-300, 300 are designated Market Auction Preferred Shares, Series H-1 through H-300, 300 are designated Market Auction Preferred Shares, Series I-1 through I-300 and 300 are designated Market Auction Preferred Shares, Series J-1 through J-300, and the remaining shares of such preferred stock are not subject to any designation).

Except as required by the terms of any series of the Market Auction Preferred Stock or any Company Stock Options or as permitted by Section 5.1(e), there are no outstanding obligations of the Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire any Company Securities. SECTION 3.6 Subsidiaries. ------------ (a) Each Subsidiary of the Company is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, has all powers and all governmental licenses, authorizations, consents and approvals required to carry on its business as now conducted, except for those the absence of which would not, individually or in the aggregate, have, or be reasonably likely to have, a Material Adverse Effect on the Company.

Reg. section 1.1502-6 (and any comparable provision of the tax laws of any state, local or foreign jurisdiction) to the affiliated group of which the Company is the common parent. For purposes of this Agreement, "Taxes" shall mean any and all taxes, charges, fees, levies or other assessments, including, without limitation, all net income, gross income, gross receipts, excise, stamp, real or personal property, ad valorem, withholding, social security (or similar), unemployment, occupation, use, production, service, service use, license, net worth, payroll, franchise, severance, transfer, recording, employment, premium, windfall profits, environmental (including taxes under Section 59A of the Code), customs duties, capital stock, profits, disability, sales, registration, value added, alternative or add-on minimum, A-17

SECTION 3.14 Employee Benefit Plans. ---------------------- (a) The Company has provided Parent with a list (set forth in Section 3.14(a) of the Company Disclosure Schedule) identifying each material "employee benefit plan", as defined in section 3(3) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), each material employment, severance or similar contract, plan, arrangement or policy applicable to any director, former director, employee or former employee of the Company and each material plan or arrangement (written or oral), providing for compensation, bonuses, profit-sharing, stock option or other stock related rights or other forms of incentive or deferred compensation, vacation benefits, insurance coverage (including any self-insured arrangements), health or medical benefits, disability benefits, workers' compensation, supplemental unemployment benefits, severance benefits and post-employment or retirement benefits (including compensation, pension, health, medical or life insurance benefits) which is maintained, administered or contributed to by the Company or any Subsidiary and covers any employee or director or former employee or director of the Company or any Subsidiary, or under which the Company has any liability; provided however, that such list need not include any Company Benefit Plan that constitutes a Foreign Company Benefit Plan (as defined below). The material plans, agreements or arrangements of the Company and its Subsidiaries referred to in the first sentence of this paragraph (a) (excluding any such plan that is a "multiemployer plan", as defined in section 3(37) of ERISA, but including Foreign Company Benefit Plans) are referred to collectively herein as the "Company Benefit Plans." "Foreign Company Benefit Plan" means any Company Benefit Plan of the Company or any of its Subsidiaries that is governed by the laws of any jurisdiction other than the United States. To the extent practicable, the Company shall provide and deliver to Parent a list of Foreign Company Benefit Plans as soon as practicable. (b) Each Company Benefit Plan has been established and maintained in compliance with its terms and with the requirements prescribed by any and all statutes, orders, rules and regulations (including but not limited to, to the extent applicable, ERISA and the Code) which are applicable to such Plan, except where failure to so comply would not, individually or in the aggregate, have, or be reasonably likely to have, a Material Adverse Effect on the Company. A-18

(c) Neither the Company nor any affiliate of the Company has incurred a liability under Title IV of ERISA that has not been satisfied in full, and no condition exists that presents a material risk to the Company or any affiliate of the Company of incurring any such liability other than liability for premiums due the Pension Benefit Guaranty Corporation (which premiums have been paid when due). (d) Each Company Benefit Plan which is intended to be qualified under section 401(a) of the Code is so qualified and has been so qualified during the period from its adoption to date, and each trust forming a part thereof is exempt from federal income tax pursuant to section 501(a) of the Code and, to the knowledge of the Company, no circumstances exist which will adversely affect such qualification or exemption. (e) Section 3.14(e) of the Company Disclosure Schedule sets forth (a) with respect to directors and officers of the Company as a group, the aggregate amount of all severance and similar benefits, including enhanced or accelerated benefits, to which such officers and directors will become entitled (including any acceleration of vesting or lapse of repurchase rights or obligations with respect to any Company Stock Option Plans or other benefit under any compensation plan or arrangement of the Company), and (b) the aggregate amount of all severance and similar benefits, including enhanced or accelerated benefits, payable in cash or stock to which all other United States payroll employees of the Company and its Subsidiaries (the "Company U.S. Employees") will become entitled, in each case, (i) solely as a result of obtaining the Company Stockholder Approval or the transactions contemplated hereby and (ii) if a "second" trigger, including, but not limited to, a termination for "good reason" or without "cause," is applicable, assuming it has occurred (collectively, (i) and (ii) are hereinafter defined as the "Benefit Triggers"). With regard to employees of the Company and its Subsidiaries other than the Company U.S. Employees (the "Company Non-U.S. Employees"), there are severance pay plans (some legally mandated and others Company designed) in many countries around the world which provide severance payments in the event of termination. To the knowledge of the Company, there are no severance agreements with respect to the Company Non-U.S. Employees which provide enhanced severance on account of a change in control which would be triggered by the transactions contemplated hereby. The Company Disclosure Schedule sets forth the aggregate amounts for the Retirement Plan which will become vested upon a Change of Control. This amount is based on the 1999 Actuarial Reports. In addition, the comparable amounts for Supplement #1 and Supplement #3, calculated as of July 2000, are also disclosed. To the Company's knowledge, there are no other retirement plans which require accelerated vesting solely due to the transactions contemplated hereunder. (f) Except as reflected in the Company Commission Documents filed prior to the date hereof, no Company Benefit Plan provides post-retirement health and medical, life or other insurance benefits for retired employees of the Company or any of its Subsidiaries. (g) There has been no amendment to, written interpretation or announcement (whether or not written) by the Company or any of its Subsidiaries relating to, or change in, employee participation or coverage under, any Company Benefit Plan (other than a Foreign Company Benefit Plan) which would increase materially the expense of maintaining such A-19

Company Benefit Plan above the level of the expense incurred in respect thereof for the 12 months ended on the Company Balance Sheet Date. (h) The Company and its Subsidiaries are in compliance in all material respects with all applicable material federal, state and local laws, rules and regulations respecting employment, employment practices, labor, terms and conditions of employment and wages and hours, including all civil rights and anti-discrimination laws, rules and regulations (collectively, "Anti-Discrimination Laws"), and no material work stoppage or slowdown or labor strike against the Company or any of its Subsidiaries is pending or threatened, nor is the Company or any of its Subsidiaries involved in or threatened with labor disputes, grievances, or litigation relating to labor matters, including with respect to Anti-Discrimination Laws, involving classes or alleged classes of persons. SECTION 3.15 Compliance with Laws. Neither the Company nor any of its -------------------- Subsidiaries is in violation of, or has since January 1, 1998 violated, any applicable provisions of any laws, statutes, ordinances or regulations except for any violations that, individually or in the aggregate, would not have, or be reasonably likely to have, a Material Adverse Effect on the Company. SECTION 3.16 Finders' or Advisors' Fees. Except for Credit Suisse First -------------------------- Boston Corporation and Morgan Stanley & Co. Incorporated, copies of whose engagement agreements have been provided to Parent, there is no investment banker, broker, finder or other intermediary which has been retained by or is authorized to act on behalf of the Company or any of its Subsidiaries who might be entitled to any fee or commission in connection with the transactions contemplated by this Agreement. SECTION 3.17 Environmental Matters. --------------------- (a) Except as set forth in the Company Commission Documents filed prior to the date hereof and with such exceptions as, individually or in the aggregate, would not have, or be reasonably likely to have, a Material Adverse Effect on the Company, (i) no notice, notification, demand, request for information, citation, summons, complaint or order has been received by, and no investigation, action, claim, suit, proceeding or review is pending or, to the knowledge of the Company or any of its Subsidiaries, threatened by any Person against, the Company or any of its Subsidiaries, and no penalty has been assessed against the Company or any of its Subsidiaries, in each case, with respect to any matters relating to or arising out of any Environmental Law; (ii) the Company and its Subsidiaries are and have been in compliance with all Environmental Laws; (iii) there are no liabilities of or relating to the Company or any of its Subsidiaries relating to or arising out of any Environmental Law of any kind whatsoever, whether accrued, contingent, absolute, determined, determinable or otherwise, and there is no existing condition, situation or set of circumstances which could reasonably be expected to result in such a liability; and (iv) there has been no environmental investigation, study, audit, test, review or other analysis conducted of which the Company has knowledge in relation to any current or prior business of the Company or any of its Subsidiaries or any property or facility now or previously owned, leased or operated by the Company or any of its Subsidiaries which has not been delivered to A-20

Parent prior to the date hereof. (b) For purposes of this Section 3.17 and Section 4.17, the term "Environmental Laws" means federal, state, local and foreign statutes, laws (including, without limitation, common law), judicial decisions, regulations, ordinances, rules, judgments, orders, codes, injunctions, permits, governmental agreements or governmental restrictions relating to human health and safety, the environment or to pollutants, contaminants, wastes, or chemicals. SECTION 3.18 Opinion of Financial Advisor.

(b) Neither the Company nor any of its affiliates has taken or agreed to take any action or is aware of any fact or circumstance with respect to the Company that would prevent the Merger from qualifying (i) for "pooling of interests" accounting treatment as described in (a) above or (ii) as a reorganization within the meaning of Section 368 of the Code (a "368 Reorganization"). (c) Immediately after the execution of this Agreement, the Company will terminate all stock repurchase programs (provided that the Company shall be permitted to effect the redemption contemplated by Section 5.3). SECTION 3.20 Pooling Letter. The Company has received a letter from Arthur -------------- Andersen LLP dated as of October 15, 2000 and addressed to the Company, a copy of which has been delivered to Parent, stating that Arthur Andersen LLP concurs with the Company management's conclusion that, as of October 15, 2000, the Company is eligible to participate in a transaction accounted for as a "pooling of interests" under Opinion 16 (Business Combination) of the Accounting Principles Board of the American Institute of Certified Public Accountants and the rules and regulations of the Commission. SECTION 3.21 Takeover Statutes. The Board of Directors of the Company has ----------------- taken the necessary action to render section 203 of the Delaware Law, any other potentially applicable antitakeover or similar statute or regulation and the supermajority voting provisions of Article XIII of the Company's certificate of incorporation and Article VII of the Company's by-laws inapplicable to this Agreement and the Company Option Agreement and the transactions contemplated hereby and thereby. A-21

SECTION 3.22 Stockholder Rights Plan.

Parent is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the character of the property owned or leased by it or the nature of its activities makes such qualification necessary, except for those jurisdictions where the failure to be so qualified would not, individually or in the aggregate, have, or be reasonably likely to have, a Material Adverse Effect on Parent. Since the A-22

date of its incorporation, Merger Subsidiary has not engaged in any activities other than in connection with or as contemplated by this Agreement.

The affirmative vote of holders of at least a majority of the outstanding shares of Parent Common Stock in favor of the Name Change Amendment is the only vote of the holders of any of the Parent's capital stock necessary in connection with obtaining the Name Change Amendment. The affirmative vote in favor of the Common Stock Issuance of a majority of the votes cast with respect to the Common Stock Issuance by the holders of Parent Common Stock (provided that the total number of the votes cast in favor of or against the Common Stock Issuance represents at least a majority of the outstanding shares of Parent Common Stock) is the only vote of the holders of any of Parent's capital stock necessary in connection with obtaining the Common Stock Issuance Approval. Assuming due authorization, execution and delivery of this Agreement and the Option Agreements by the Company, this Agreement constitutes a valid and binding agreement of each of Parent and Merger Subsidiary and each Option Agreement constitutes a valid and binding agreement of Parent, in each case enforceable against such party in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles.

SECTION 4.4 Non-Contravention. The execution, delivery and performance by ----------------- Parent and Merger Subsidiary of this Agreement, and by Parent of the Option Agreements, and the consummation by Parent and Merger Subsidiary of the transactions contemplated hereby and thereby do not and will not, assuming compliance with the matters referred to in Sections 4.2 and 4.3, (a) contravene or conflict with the certificate of incorporation or by-laws of Parent or Merger Subsidiary, (b) contravene or conflict with or constitute a violation of any provision of any law, regulation, judgment, injunction, order or decree binding upon or applicable to Parent or any of its Subsidiaries, (c) constitute a default under or give rise to any right of termination, cancellation or acceleration of any right or obligation of Parent or any of its Subsidiaries or to a loss of any benefit to which Parent or any of its Subsidiaries is entitled under any provision of any agreement, contract or other instrument binding upon Parent or any of its Subsidiaries or any license, franchise, permit or other similar authorization held by Parent or any of its Subsidiaries or (d) result in the creation or imposition of any Lien on any asset of Parent or any of its Subsidiaries, except for such contraventions, conflicts or violations referred to in clause (b) or defaults, rights of termination, cancellation or acceleration, or losses or Liens referred to in clause (c) or (d) that would not, individually or in the aggregate, have, or be reasonably likely to have, a Material Adverse Effect on Parent. Neither Parent nor any Subsidiary of Parent is a party to any agreement that expressly limits the ability of Parent or any Subsidiary of Parent to compete in or conduct any line of business or compete with any Person or in any geographic area or during any period of time except to the extent that any such limitation, individually or in the aggregate, would not have, or be reasonably likely to have, a Material Adverse Effect on Parent.

(b) Without limiting Section 7.1(a), Parent and the Company shall subject to Sections 7.1(c) and 7.1(d), as applicable: A-42

(c) Notwithstanding anything else contained herein, the provisions of this Section 7.1 shall not be construed to require either party to undertake any efforts or to take any action if such efforts or action would, or would reasonably be expected to, result in a Material Adverse Effect on Parent and its Subsidiaries (including the Surviving Corporation and its Subsidiaries), taken as a whole, at or after the Effective Time; provided, further, that any requirement to divest or hold separate, or limit in any material respect the operations of the business of Parent and its Subsidiaries (prior to Closing) involving the refining, marketing or transportation of petroleum products in the Western United States, other than with respect to insignificant operations of such business shall be deemed for purposes of this Section 7.1(c) and Sections 8.1(d), 8.1(i), 8.1(j), 8.1(k) and 8.1(l) to result in a Material Adverse Effect. (d) (i) The parties anticipate that there will be objections raised by the United States Federal Trade Commission or the Antitrust Division of the United States Department of Justice to the combination of Parent's United States downstream operations with the Company's interests in the Joint Ventures (collectively, the "Alliance Interests").

(iii) If the stockholders of the Company, at the Company Stockholder Meeting (which shall not take place prior to the Condition Satisfaction Time), approve and adopt the Merger and the Merger Agreement in accordance with Delaware Law, then, immediately upon the conclusion of such meeting, the parties shall consummate the Closing. If the utilization of the Trust Agreement, described below, is required in order to meet immediately any remaining conditions to Closing, the Company shall cause all of the then outstanding capital stock of the Subsidiary or the Subsidiaries of the Company which own the Alliance Interests, and such other assets as Parent and the Company shall agree, to be placed into an irrevocable trust pursuant to an Agreement and Declaration of Trust (the "Trust Agreement") substantially in the form of Annex 7.1 to this Agreement, with only such changes as are (x) required by any governmental body, agency, official or authority or (y) mutually agreed by Parent, the Company and the Trustees.

All information obtained by Parent or the Company pursuant to this Section 7.3 shall be kept confidential in accordance with, and shall otherwise be subject to the terms of, the Confidentiality Agreement dated February 5, 1999 between Parent and the Company (the "Confidentiality Agreement"). A-44

SECTION 7.4 Tax and Accounting Treatment. Neither Parent nor the Company ---------------------------- shall, nor shall they permit their Subsidiaries to take, any action, and Parent and the Company shall not, and shall ensure that its Subsidiaries do not, fail to take any action which action or failure to act would prevent, or would be reasonably likely to prevent, the Merger from qualifying (a) for "pooling of interests" accounting treatment as described in Section 3.19(a) or (b) as a 368 Reorganization. SECTION 7.5 Public Announcements. Parent and the Company will consult with -------------------- each other before issuing any press release or making any public statement with respect to this Agreement and the transactions contemplated hereby and shall not issue any press release or make any public statement without the prior consent of the other party, which consent shall not be unreasonably withheld.

the party delivering the letter, may be, as of the date of the Company Stockholder Meeting or Parent Stockholder Meeting, as applicable, its "affiliates" for purposes of SEC Accounting Series Releases 130 and 135 and/or, in the case of the Company, for purposes of Rule 145 under the Securities Act, and (ii) shall use its reasonable best efforts to cause each Person who is identified as an "affiliate" of it in such letter to deliver, as promptly as practicable but in no event later than 30 days prior to the Closing (or after such later date as the Parent and the Company may agree) to Parent in the case of affiliates of Parent, a signed agreement substantially in the form attached as Exhibit C-1, and in the case of affiliates of the Company, substantially in the forms attached as Exhibits C-2 and C-3. Each of Parent and the Company shall notify the other party from time to time after the delivery of the letter described in Section 7.8(a)(i) of any Person not identified on such letter who then is, or may be, such an "affiliate" and use its reasonable best efforts to cause each additional Person who is identified as an "affiliate" to execute a signed agreement or agreements as set forth in this Section 7.8(a). (b) Shares of Parent Common Stock and shares of Company Common Stock beneficially owned by each such "affiliate" of Parent or Company who has not provided a signed agreement or agreements, as applicable, in accordance with Section 7.8(a) shall not be transferable during any period prior to and after the Effective Time if, as a result of this transfer during any such period, taking into account the nature, extent and timing of this transfer and similar transfers by all other "affiliates" of Parent and the Company, this transfer will, in the reasonable judgment of accountants of Parent, interfere with, or prevent the Merger from being accounted for, as a "pooling-of-interests" under GAAP and/or the rules and regulations of the SEC. Neither Parent or the Company shall register, or allow its transfer agent to register, on its books, any transfer of any shares of Parent Common Stock or Company Common Stock of any affiliate of Parent or the Company who has not provided a signed agreement in accordance with Section 7.8(a) unless the transfer is made in compliance with the foregoing. SECTION 7.9 Payment of Dividends. From the date hereof until the Effective -------------------- Time, Parent and the Company will coordinate with each other regarding the declaration of dividends in respect of the shares of Parent Common Stock and the shares of Company Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties that holders of shares of Company Common Stock will not receive two dividends, or fail to receive one dividend, for any single calendar quarter with respect to their shares of Company Common Stock and the shares of Parent Common Stock any holder of shares of Company Common Stock receives in exchange therefor in connection with the Merger. SECTION 7.10 No Solicitation. --------------- (a) Each of Parent and the Company and their respective Subsidiaries will not, and Parent and the Company will direct and use their respective best efforts to cause their and their Subsidiaries' respective officers, directors, employees, investment bankers, consultants, attorneys, accountants, agents and other representatives not to, directly or indirectly, take any action to solicit, initiate, encourage or facilitate the making of any Acquisition Proposal (including without limitation by amending, or granting any waiver under, the Parent Rights Agreement or the Company Rights Agreement, as applicable) or any inquiry with respect thereto A-46

or engage in discussions or negotiations with any Person with respect thereto, or disclose any nonpublic information or afford access to properties, books or records to, any Person that has made, or to such party's knowledge, is considering making, any Acquisition Proposal. Nothing contained in this Agreement shall prevent the Board of Directors of Parent or the Company from complying with Rule 14e-2 under the Exchange Act with regard to an Acquisition Proposal; provided that the Board of Directors of such party shall not recommend that the stockholders of such party tender their shares in connection with a tender offer or exchange offer except to the extent that, after receiving a Superior Proposal, such Board of Directors of such party determines in its good faith judgment, after receiving the advice of outside legal counsel, that, in light of such Superior Proposal, failure to make such a recommendation would be reasonably likely to be inconsistent with fulfilling the fiduciary duties of the Board of Directors to such party's stockholders under applicable law and such party shall have complied with the procedure set forth in Section 5.2 or 6.4, to the extent applicable. Notwithstanding anything to the contrary in this Agreement, prior to the date of approval of this Agreement and the Merger by the stockholders of Parent or the Company, as applicable, Parent or the Company may (A) furnish information and access to a third party, but only in response to a request for information or access, to any Person making an Acquisition Proposal to the board of directors of Parent or the Company, as applicable, after the date hereof which was not knowingly encouraged, solicited or initiated by Parent or the Company, as applicable, or any of its affiliates or any director, employee, representative or agent of Parent or the Company, as applicable, or any of its respective Subsidiaries (including, without limitation, any investment banker, attorney or accountant retained by Parent or the Company or any of its Subsidiaries) on or after the date hereof and (B) may participate in discussions and negotiate with such Person concerning any such Acquisition Proposal, if and only if, in any such case set forth in clause A or B of this paragraph, (i) the Board of Directors of Parent or Company, as applicable, concludes in good faith, after receipt of the advice of a financial advisor of nationally recognized reputation and outside legal counsel, that such Acquisition Proposal is reasonably likely to result in a Superior Proposal with respect to Parent or the Company, as applicable, (ii) the Company or Parent, as applicable, complies with all of its obligations under this Agreement, and (iii) the board of directors of Parent or the Company, as applicable, receives from the Person making such an Acquisition Proposal an executed confidentiality agreement the material terms of which are (without regard to the terms of such Acquisition Proposal) in all material respects (x) no less favorable to the Company or Parent, as applicable, and (y) no less restrictive to the Person making such Acquisition Proposal than those contained in the Confidentiality Agreement. (b) Any party receiving an Acquisition Proposal will (A) promptly (and in no event later than 48 hours after receipt of any Acquisition Proposal) notify (which notice shall be provided orally and in writing and shall identify the Person making such Acquisition Proposal and set forth the material terms thereof) the other party to this Agreement after receipt of any Acquisition Proposal, any indication of which such party has knowledge that any Person is considering making an Acquisition Proposal, or any request for nonpublic information relating to such party or any Subsidiary of such party or for access to the properties, books or records of such party or any Subsidiary of such party by any Person that has made, or to such party's knowledge may be considering making, an Acquisition Proposal, and (B) will keep the other party to this Agreement informed of the status and material terms of (including all changes to the A-47

status or material terms of) any such Acquisition Proposal or request. Each of Parent and the Company (x) shall, and shall cause their respective Subsidiaries to, immediately cease and cause to be terminated and shall use reasonable best efforts to cause its and their officers, directors, employees, investment bankers, consultants, attorneys, accountants, agents and other representatives to, immediately cease and cause to be terminated, all discussions and negotiations, if any, that have taken place prior to the date hereof with any Persons with respect to any Acquisition Proposal and (y) shall promptly request each Person, if any, that has executed a confidentiality agreement within the 9 months prior to the date hereof in connection with its consideration of any Acquisition Proposal to return or destroy all confidential information heretofore furnished to such Person by or on behalf of it or any of its Subsidiaries. For purposes of this Agreement, "Acquisition Proposal" means any bona fide written offer or proposal for, or any written indication of interest in, any (i) direct or indirect acquisition or purchase of any business or assets of Parent or the Company or any of their respective Subsidiaries that, individually or in the aggregate, constitutes 20% or more of the net revenues, net income or assets of such party and its Subsidiaries, taken as a whole, (ii) direct or indirect acquisition or purchase of 20% or more of any class of equity securities of Parent or the Company or any of their respective Subsidiaries whose business constitutes 20% or more of the net revenues, net income or assets of such party and its Subsidiaries, taken as a whole, (iii) tender offer or exchange offer that, if consummated, would result in any Person beneficially owning 20% or more of any class of equity securities of Parent or the Company or any of their respective Subsidiaries whose business constitutes 20% or more the net revenues, net income or assets of such party and its Subsidiaries, taken as a whole, or (iv) merger, consolidation, business combination, joint venture, partnership, recapitalization, liquidation, dissolution or similar transaction involving Parent or the Company or any of their respective Subsidiaries whose business constitutes 20% or more of the net revenue, net income or assets of such party and its Subsidiaries, taken as a whole, other than the transactions contemplated by this Agreement; provided, however, that (a) with respect to Parent, an offer or proposal shall not be deemed an Acquisition Proposal if (x) the execution of agreement with respect to, and consummation of, the transaction contemplated thereby would not be reasonably likely to prevent the Parent and Merger Subsidiary from consummating the Merger or to materially delay Parent's or Merger Subsidiary's ability to consummate the Merger and (y) execution of an agreement with respect to the transaction contemplated thereby is not prohibited by Section 6.1, or, if the execution of such agreement would be prohibited by Section 6.1, such an agreement will not be entered into until after the provisions contained in Section 6.1 are no longer in effect and (b) with respect to the Company, any offer or proposal for the disposition by the Company of the Alliance Interests shall not be deemed to be an Acquisition Proposal. For purposes of this Agreement, "Superior Proposal" means any bona fide written Acquisition Proposal for or in respect of at least a majority of the outstanding shares of Company Common Stock, or Parent Common Stock, as applicable (i) on terms that the Board of Directors of Parent or the Company, as applicable, determines in its good faith judgment (after consultation with, and taking into account the advice of, a financial advisor of nationally recognized reputation, taking into account all the terms and conditions of the Acquisition Proposal, including any break-up fees, expense reimbursement provisions and conditions to consummation) are more favorable from a financial point of view to its stockholders than the Merger and the other transactions contemplated hereby and (ii) that A-48

constitutes a transaction that is reasonably likely to be consummated on the terms set forth, taking into account all legal, financial, regulatory and other aspects of such proposal. (c) Each of the Company and Parent agrees that it will take the necessary steps promptly to inform its Subsidiaries and its officers, directors, investment bankers, consultants, attorneys, accountants, agents and other representatives of the obligations undertaken in this Section 7.10. SECTION 7.11 Letters from Accountants. ------------------------ (a) Parent shall use reasonable best efforts to cause to be delivered to Parent and the Company two letters from PricewaterhouseCoopers LLP, one dated the date on which the Form S-4 shall become effective and one dated the Closing Date, each addressed to the Boards of Directors of Parent and the Company, in form and substance reasonably satisfactory to the Company and customary in scope and substance for comfort letters delivered by independent public accountants in connection with registration statements similar to the Form S-4. (b) Parent shall use reasonable best efforts to cause to be delivered to Parent and the Company a letter from PricewaterhouseCoopers LLP, dated as of the Closing Date, addressed to the Boards of Directors of Parent and the Company, stating that PricewaterhouseCoopers LLP concurs with Parent's management's conclusion that accounting for the Merger as a "pooling of interests" under Opinion No. 16 (Business Combination) of the Accounting Principles Board of the American Institute of Certified Public Accountants and the rules and regulations of the Commission is appropriate if the Merger is closed and consummated in accordance with the terms hereof. (c) The Company shall use reasonable best efforts to cause to be delivered to the Company and Parent two letters from Arthur Andersen LLP, one dated the date on which the Form S-4 shall become effective and one dated the Closing Date, each addressed to the Boards of Directors of the Company and Parent, in form and substance reasonably satisfactory to Parent and customary in scope and substance for comfort letters delivered by independent public accountants in connection with registration statement similar to the Form S-4. (d) The Company shall use reasonable best efforts to cause to be delivered to the Company a letter from Arthur Andersen LLP, dated as of the Closing Date, addressed to the Board of Directors of the Company, stating that Arthur Andersen LLP concurs with the Company's management's conclusion that the Company is eligible to participate in a transaction accounted for as a "pooling of interests" under Opinion No. 16 (Business Combination) of the Accounting Principles Board of the American Institute of Certified Public Accountants and the rules and regulations of the Commission. SECTION 7.12 Takeover Statutes. If any anti-takeover or similar statute or ----------------- regulation is or may become applicable to the transactions contemplated hereby, each of the parties and its Board of Directors shall grant such approvals and take all such actions as are legally permissible so that the transactions contemplated hereby may be consummated as promptly as practicable on A-49

the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any such statute or regulation on the transactions contemplated hereby. SECTION 7.13 Headquarters. After the Effective Time, the headquarters of ------------ Parent shall continue to be located in San Francisco, California. SECTION 7.14 Section 16(b). Parent shall take all such steps reasonably ------------- necessary to cause the transactions contemplated hereby and any other dispositions of equity securities of the Company (including derivative securities) or acquisitions of Parent equity securities (including derivative securities) in connection with this Agreement by each individual who (a) is a director or officer of the Company or (b) at the Effective Time, will become a director or officer of Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

ANNEX B STOCK OPTION AGREEMENT ---------------------- THIS STOCK OPTION AGREEMENT (this "Agreement"), dated as of October 15, 2000, between Chevron Corporation, a Delaware corporation ("Parent"), and Texaco Inc., a Delaware corporation (the "Company"). W I T N E S S E T H : WHEREAS, Parent and the Company are concurrently with the execution and delivery of this Agreement entering into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which, among other things, Merger Subsidiary will merge with and into the Company on the terms and subject to the conditions stated therein; and WHEREAS, in order to induce Parent to enter into the Merger Agreement and as a condition for Parent's agreeing so to do, the Company has granted to Parent the Stock Option (as hereinafter defined), on the terms and conditions set forth herein; NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth herein and in the Merger Agreement, and for other good and valuable consideration, the adequacy of which is hereby acknowledged, the parties hereto agree as follows: Section 1. Definitions. Capitalized terms used and not defined herein have ----------- the respective meanings assigned to them in the Merger Agreement. Section 2. Grant of Stock Option. --------------------- (a) The Company hereby grants to Parent an irrevocable option (the "Stock Option") to purchase, on the terms and subject to the conditions hereof, for $53.71 per share (the "Exercise Price") in cash, up to 107,000,000 fully paid and non-assessable shares (the "Option Shares") of the Company's common stock, par value $3.125 per share (the "Common Stock"). The Exercise Price and number of Option Shares shall be subject to adjustment as provided in Sections 2(b) and 6 below. (b) In the event that any (i) additional shares of Common Stock are issued or otherwise become outstanding after the date of the Agreement (other than pursuant to this Agreement) or (ii) shares of Common Stock are redeemed, repurchased, retired or otherwise cease to be outstanding after the date of the Agreement, the number of shares of Common Stock subject to the Stock Option shall be increased or decreased, as appropriate, so that after such issuance or redemption, such number equals 19.9% of the number of shares of Common Stock then issued and outstanding (without giving effect to any shares subject or issued pursuant to the Stock Option). Nothing contained in this Section 2(b) or elsewhere in this Agreement shall be deemed to authorize Parent or the Company to breach any provision of the Merger Agreement. B-1

Section 3. Exercise of Stock Option. ------------------------ (a) Parent may, subject to the provisions of this Section, exercise the Stock Option, in whole or in part, at any time or from time to time, after the occurrence of a Company Trigger Event (defined below) and prior to the Termination Date. "Termination Date" shall mean the earliest of (i) the Effective Time of the Merger, (ii) 90 days after the date full payment contemplated by Section 10.5 of the Merger Agreement is made by the Company to Parent thereunder or (iii) one day after the date of the termination of the Merger Agreement so long as, in the case of this clause (iii), no Company Trigger Event has occurred or could still occur pursuant to Section 10.5 of the Merger Agreement. Notwithstanding the occurrence of the Termination Date, Parent shall be entitled to purchase Option Shares pursuant to any exercise of the Stock Option, on the terms and subject to the conditions hereof, to the extent Parent exercised the Stock Option prior to the occurrence of the Termination Date. A "Company Trigger Event" shall mean an event the result of which is that the Company becomes obligated to pay a fee to Parent pursuant to Section 10.5 of the Merger Agreement. (b) Parent may purchase Option Shares pursuant to the Stock Option only if all of the following conditions are satisfied: (i) no preliminary or permanent injunction or other order issued by any federal or state court of competent jurisdiction in the United States shall be in effect prohibiting delivery of the Option Shares, (ii) any applicable waiting period under the HSR Act shall have expired or been terminated, and (iii) any prior notification to or approval of any other regulatory authority in the United States or elsewhere required in connection with such purchase shall have been made or obtained, other than those which if not made or obtained would not reasonably be expected to result in a Material Adverse Effect on the Company and its Subsidiaries, taken as a whole. (c) If Parent shall be entitled to and wishes to exercise the Stock Option, it shall do so by giving the Company written notice (the "Stock Exercise Notice") to such effect, specifying the number of Option Shares to be purchased and a place and closing date not earlier than three business days nor later than 10 business days from the date of such Stock Exercise Notice. If the closing cannot be consummated on such date because any condition to the purchase of Option Shares set forth in Section 3(b) has not been satisfied or as a result of any restriction arising under any applicable law or regulation, the closing shall occur five days (or such earlier time as Parent may specify) after satisfaction of all such conditions and the cessation of all such restrictions; provided that in no event shall the closing of the purchase be postponed by more than nine months after the Termination Date as a result of this clause (c). (d) So long as the Stock Option is exercisable pursuant to the terms of Section 3(a) Parent may elect to send a written notice to the Company (the "Cash Exercise Notice") specifying a date not later than 20 business days and not earlier than 10 business days following the date such notice is given on which date the Company shall pay to Parent in exchange for the cancellation of the relevant portion of the Stock Option an amount in cash equal to the Spread (as hereinafter defined) multiplied by all or such portion of the Option Shares subject to the Stock Option as Parent shall specify. As used herein, "Spread" shall mean the excess, if any, over the Exercise Price of the higher of (x) if applicable, the highest price per share of Common Stock B-2

paid or proposed to be paid by any Person pursuant to any Acquisition Proposal relating to the Company (the "Alternative Exercise Price") or (y) the average of the closing price of the shares of Common Stock on the NYSE at the end of the regular session, as reported on the Consolidated Tape, Network A for the five consecutive trading days ending on and including the trading date immediately preceding the date on which the Cash Exercise Notice is given (the "Average Market Price"). If the Alternative Exercise Price includes any property other than cash, the Alternative Exercise Price shall be the sum of (i) the fixed cash amount, if any, included in the Alternative Exercise Price plus (ii) the fair market value of such other property. If such other property consists of securities with an existing public trading market, the average of the closing prices (or the average of the closing bid and asked prices if closing prices are unavailable) for such securities in their principal public trading market on the five trading days ending five days prior to the date on which the Cash Exercise Notice is given shall be deemed to equal the fair market value of such property. If such other property includes anything other than cash or securities with an existing public trading market, the Alternative Exercise Price shall be deemed to equal the Average Market Price. Upon exercise of its right pursuant to this Section 3(d) and the receipt by Parent of the applicable cash amount with respect to the Option Shares or the applicable portion thereof, the obligations of the Company to deliver Option Shares pursuant to Section 3(e) shall be terminated with respect to the number of Option Shares specified in the Cash Exercise Notice. The Spread shall be appropriately adjusted, if applicable, to give effect to Section 6. (e) (i) At any closing pursuant to Section 3(c) hereof, Parent shall make payment to the Company of the aggregate purchase price for the Option Shares to be purchased and the Company shall deliver to Parent a certificate representing the purchased Option Shares, registered in the name of Parent or its designee and (ii) at any closing pursuant to Section 3(d) hereof, the Company will deliver to Parent cash in an amount determined pursuant to Section 3(d) hereof. Any payment made by Parent to the Company, or by the Company to Parent, pursuant to this Agreement shall be made by wire transfer of immediately available funds to a bank designated by the party receiving such funds, provided that the failure or refusal by the Company to designate such a bank account shall not preclude Parent from exercising the Stock Option. If at the time of the issuance of Option Shares pursuant to the exercise of the Stock Option, Company Rights or any similar securities are outstanding, then the Option Shares issued pursuant to such exercise shall be accompanied by corresponding Company Rights or such similar securities. (f) Certificates for Common Stock delivered at the closing described in Section 3(c) hereof shall be endorsed with a restrictive legend which shall read substantially as follows: "The transfer of the shares represented by this certificate is subject to resale restrictions arising under the Securities Act of 1933, as amended. The shares represented by this certificate are also subject to repurchase by the Issuer pursuant to the Stock Option Agreement dated as of October 15, 2000, a copy of which agreement may be obtained upon request from the Issuer." B-3

It is understood and agreed that the above legend shall be removed by delivery of substitute certificate(s) without this reference (i) if Parent shall have delivered to the Company a copy of a no-action letter from the staff of the Securities and Exchange Commission, or a written opinion of counsel, in form and substance reasonably satisfactory to the Company, to the effect that such legend is not required for purposes of, or resale may be effected pursuant to an exemption from registration under, the Securities Act or (ii) in connection with any sale registered under the Securities Act. In addition, these certificates shall bear any other legend as may be required by applicable law. (g) At any time following the exercise by Parent of the Stock Option, the Company shall have the right, within 5 business days after written notice to Parent, to purchase for cash all of the Option Shares received by Parent pursuant to this Agreement at a purchase price per share equal to the higher of (x) the Alternative Exercise Price or (y) the Average Market Price. At any closing pursuant to this Section 3(g), the Company shall make payment to Parent of the aggregate purchase price for the Option Shares to be purchased and Parent shall deliver to the Company a certificate representing the purchased Option Shares. Section 4. Representations and Warranties of the Company. The Company --------------------------------------------- hereby represents and warrants to Parent as follows: (a) The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware. The execution, delivery and performance by the Company of this Agreement and the consummation by the Company of the transactions contemplated hereby (i) are within the Company's corporate powers, (ii) have been duly authorized by all necessary corporate action, (iii) require no action by or in respect of, or filing with, any governmental body, agency or official, except for compliance with any applicable requirements of the HSR Act, the Exchange Act, the Securities Act, and laws, rules and regulations in foreign jurisdictions governing antitrust or merger control matters (iv) assuming compliance with the matters referred to in clause (iii), do not contravene, or constitute a violation of, any provision of applicable law or regulation or of the certificate of incorporation or by-laws of the Company or of any judgment, injunction, order or decree binding upon the Company or any of its Subsidiaries, (v) do not and will not constitute a default under or give rise to a right of termination, cancellation or acceleration of any right or obligation of the Company or any of its Subsidiaries or to a loss of any benefit to which the Company or any of its Subsidiaries is entitled under any provision of any agreement, contract or other instrument binding upon the Company or any of its Subsidiaries or any license, franchise, permit or other similar authorization held by the Company or any of its Subsidiaries, and (vi) do not and will not result in the creation or imposition of any Lien on any asset of the Company or any of its Subsidiaries, except for such contraventions, conflicts or violations referred to in clause (iv) or defaults, rights of termination, cancellation or acceleration, or losses or Liens referred to in clauses (v) and (vi) that would not, individually or in the aggregate, have a Material Adverse Effect on the Company. This Agreement has been duly executed and delivered by the Company and constitutes a valid and binding agreement of the Company. B-4

(b) The Company has taken all necessary corporate action to authorize and reserve and to permit it to issue, and at all times from the date hereof until such time as the obligation to deliver Option Shares upon the exercise of the Stock Option terminates, will have reserved for issuance upon any exercise of the Stock Option, the number of Option Shares subject to the Stock Option (less the number of Option Shares previously issued upon any partial exercise of the Stock Option). All of the Option Shares to be issued pursuant to the Stock Option have been duly authorized and, upon issuance and delivery thereof pursuant to this Agreement, will be duly authorized, validly issued, fully paid and nonassessable, and will be delivered free and clear of all claims, liens, charges, encumbrances and security interests (other than those created by this Agreement). Option Shares issued upon exercise of the Stock Option will not be subject to any preemptive or similar rights. The Board of Directors of the Company has resolved to, and the Company promptly after execution of this Agreement will, take all necessary action to render the Company Rights Agreement inapplicable to the grant or exercise of the Stock Option and the transactions contemplated hereby. The Board of Directors of the Company has taken all necessary action to render section 203 of the Delaware Law, or any other antitakeover statute or similar statute or regulation, and the supermajority voting provisions of Article XIII of the Company's certificate of incorporation and Article VII of the Company's by-laws inapplicable to the acquisition of the Option Shares pursuant to this Agreement. Section 5. Representations and Warranties of Parent. Parent hereby ---------------------------------------- represents and warrants to the Company as follows: Parent is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware. The execution, delivery and performance by Parent of this Agreement and the consummation of the transactions contemplated hereby (i) are within Parent's corporate powers and (ii) have been duly authorized by all necessary corporate action. The Option Shares acquired by Parent upon the exercise of the Stock Option will not be, and the Stock Option is not being, acquired by Parent with the intention of making a public distribution thereof. Neither the Stock Option nor the Option Shares acquired upon exercise of the Stock Option will be sold or otherwise disposed of by Parent except in compliance with the Securities Act. This agreement has been duly executed and delivered by Parent and constitutes a valid and binding agreement of Parent. Section 6. Adjustment upon Changes in Capitalization or Merger. --------------------------------------------------- (a) In the event of any change in the outstanding shares of Common Stock by reason of a stock dividend, stock split, reverse stock split, split-up, merger, consolidation, recapitalization, combination, conversion, exchange of shares, extraordinary or liquidating dividend or similar transaction which would affect Parent's rights hereunder, the type and number of shares or securities purchasable upon the exercise of the Stock Option and the Exercise Price shall be adjusted appropriately, and proper provision will be made in the agreements governing such transaction, as shall fully preserve the economic benefits provided hereunder to Parent and the full satisfaction of the Company's obligations hereunder. In no event shall the number of shares of Common Stock subject to the Stock Option exceed 19.9% of the number of shares of Common Stock issued and outstanding at the time of exercise (without giving effect to any shares subject or issued pursuant to the Stock Option). B-5

(b) Without limiting the foregoing, whenever the number of Option Shares purchasable upon exercise of the Stock Option is adjusted as provided in this Section 6, the Exercise Price shall be adjusted by multiplying the Exercise Price by a fraction, the numerator of which is equal to the number of Option Shares purchasable prior to the adjustment and the denominator of which is equal to the number of Option Shares purchasable after the adjustment. (c) Without limiting or altering the parties' rights and obligations under the Merger Agreement, in the event that the Company enters into an agreement (i) to consolidate with or merge into any Person, other than Parent or one of its Subsidiaries, and the Company will not be the continuing or surviving corporation in such consolidation or merger, (ii) to permit any Person, other than Parent or one of its Subsidiaries, to merge into the Company and the Company will be the continuing or surviving corporation, but in connection with such merger, the shares of Common Stock outstanding immediately prior to the consummation of such merger will be changed into or exchanged for stock or other securities of the Company or any other Person or cash or any other property, or the shares of Common Stock outstanding immediately prior to the consummation of such merger will, after such merger, represent less than 50% of the outstanding voting securities of the merged company, or (iii) to sell or otherwise transfer all or substantially all of its assets to any Person, other than Parent or one of its Subsidiaries, then, and in each such case, the agreement governing such transaction will make proper provision so that the Stock Option will, upon the consummation of any such transaction and upon the terms and conditions set forth herein, be converted into, or exchanged for, an option with identical terms appropriately adjusted to acquire the number and class of shares or other securities or property that Parent would have received in respect of Option Shares had the Stock Option been exercised immediately prior to such consolidation, merger, sale or transfer or the record date therefor, as applicable, and shall make any other necessary adjustments. The Company shall take such steps in connection with such consolidation, merger, liquidation or other such transaction as may be reasonably necessary to assure that the provisions hereof shall thereafter apply as nearly as possible to any securities or property thereafter deliverable upon exercise of the Stock Option. Section 7. Further Assurances; Remedies. ---------------------------- (a) The Company agrees to maintain, free from preemptive rights, sufficient authorized but unissued or treasury shares of Common Stock so that the Stock Option may be fully exercised without additional authorization of Common Stock after giving effect to all other options, warrants, convertible securities and other rights of third parties to purchase shares of Common Stock from the Company, and to issue the appropriate number of shares of Common Stock pursuant to the terms of this Agreement. All of the Option Shares to be issued pursuant to the Stock Option, upon issuance and delivery thereof pursuant to this Agreement, will be duly authorized, validly issued, fully paid and non-assessable, and will be delivered free and clear of all claims, liens, charges, encumbrances and security interests (other than those created by this Agreement). (b) The Company agrees not to avoid or seek to avoid (whether by charter amendment or through reorganization, consolidation, merger, issuance of rights, dissolution or B-6

sale of assets, or by any other voluntary act) the observance or performance of any of the covenants, agreements or conditions to be observed or performed hereunder by the Company. (c) The Company agrees that promptly after the occurrence of a Company Trigger Event it shall take all actions as may from time to time be required (including (i) complying with all applicable premerger notification, reporting and waiting period requirements under the HSR Act and (ii) in the event that prior notification to or approval of any other regulatory authority in the United States or elsewhere is necessary before the Stock Option may be exercised, complying with its obligations thereunder and cooperating with Parent in preparing and processing the required notices or applications) in order to permit Parent to exercise the Stock Option and purchase Option Shares pursuant to such exercise. (d) The parties agree that Parent would be irreparably damaged if for any reason the Company failed to issue any of the Option Shares (or other securities or property deliverable pursuant to Section 6 hereof) upon exercise of the Stock Option or to perform any of its other obligations under this Agreement, and that Parent would not have an adequate remedy at law for money damages in such event. Accordingly, Parent shall be entitled to specific performance and injunctive and other equitable relief to enforce the performance of this Agreement by the Company. Accordingly, if Parent should institute an action or proceeding seeking specific enforcement of the provisions hereof, the Company hereby waives the claim or defense that Parent has an adequate remedy at law and hereby agrees not to assert in any such action or proceeding the claim or defense that such a remedy at law exists. The Company further agrees to waive any requirements for the securing or posting of any bond in connection with obtaining any such equitable relief. This provision is without prejudice to any other rights that Parent may have against the Company for any failure to perform its obligations under this Agreement. Section 8. Listing of Option Shares. Promptly after the occurrence of a ------------------------ Company Trigger Event and from time to time thereafter if necessary, the Company will apply to list all of the Option Shares subject to the Stock Option on the NYSE and will use its reasonable best efforts to obtain approval of such listing as soon as practicable. Section 9. Registration of the Option Shares. --------------------------------- (a) If, within two years of the exercise of the Stock Option, Parent requests the Company in writing to register under the Securities Act any of the Option Shares received by Parent hereunder, the Company will use its reasonable best efforts to cause the offering of the Option Shares so specified in such request to be registered as soon as practicable so as to permit the sale or other distribution by Parent of the Option Shares specified in its request (and to keep such registration in effect for a period of at least 90 days), and in connection therewith the Company shall prepare and file as promptly as reasonably possible (but in no event later than 60 days from receipt of Parent's request) a registration statement under the Securities Act to effect such registration on an appropriate form, which would permit the sale of the Option Shares by Parent in accordance with the plan of disposition specified by Parent in its request. The Company shall not be obligated to make effective more than two registration statements pursuant to the foregoing sentence; provided, however, that the Company may postpone the filing of a B-7

registration statement relating to a registration request by Parent under this Section 9 for a period of time (not in excess of 90 days) if in the Company's reasonable, good faith judgment (i) such filing would require the disclosure of material information that the Company has a bona fide business purpose for preserving as confidential or (ii) the sale of Option Shares by Parent would materially interfere with any pending or anticipated acquisition, financing or transaction involving the Company or its Subsidiaries (but in no event shall the Company exercise such postponement right more than once in any twelve-month period). (b) The Company shall notify Parent in writing not less than 10 days prior to filing a registration statement under the Securities Act (other than a filing on Form S-4 or S-8 or any successor form) with respect to any shares of Common Stock. If Parent wishes to have any portion of its Option Shares included in such registration, it shall advise the Company in writing to that effect within two business days following receipt of such notice, and the Company will thereupon include the number of Option Shares indicated by Parent in such registration; provided that if the managing underwriter(s) of the offering pursuant to such registration statement advise the Company that in their opinion the number of shares of Common Stock requested to be included in such registration exceeds the number which can be sold in such offering, the Company shall only include in such registration such number or dollar amount of Option Shares which, in the good faith opinion of the managing underwriter(s), can be sold without materially and adversely affecting such offering. (c) All expenses relating to or in connection with any registration contemplated under this Section 9 and the transactions contemplated thereby (including all filing, printing, reasonable professional, roadshow and other fees and expenses relating thereto) will be at the Company's expense except for underwriting discounts or commissions and brokers' fees. The Company and Parent agree to enter into a customary underwriting agreement with underwriters upon such terms and conditions as are customarily contained in underwriting agreements with respect to secondary distributions. The Company shall indemnify Parent, its officers, directors, agents, other controlling persons and any underwriters retained by Parent in connection with such sale of such Option Shares in the customary way, and shall agree to customary contribution provisions with such persons, with respect to claims, damages, losses and liabilities (and any expenses relating thereto) arising (or to which Parent, its officers, directors, agents, other controlling persons or underwriters may be subject) in connection with any such offer or sale under the federal securities laws or otherwise, except for information furnished in writing by Parent or its underwriters to the Company. Parent and its underwriters, respectively, shall indemnify the Company to the same extent with respect to information furnished in writing to the Company by Parent and such underwriters, respectively. Section 10. Miscellaneous. ------------- (a) Extension of Exercise Periods. The periods during which Parent may ----------------------------- exercise its rights under Sections 2 and 3 hereof, or the Company may exercise its rights under Section 2(g), shall be extended in each such case at the request of Parent to the extent necessary to avoid liability by Parent under Section 16(b) of the Exchange Act by reason of such exercise. B-8

This Agreement may not be modified, ---------------------------- amended, altered or supplemented, except upon the execution and delivery of a written agreement executed by the parties hereto.

Section 11. Profit Limitation. ----------------- (a) Notwithstanding any other provision of this Agreement or the Merger Agreement, in no event shall Parent's Total Profit (as defined below) exceed $1,100,000,000 (the "Maximum Amount") and, if it otherwise would exceed such Maximum Amount, Parent at its sole election may (i) pay cash to the Company, (ii) deliver to the Company for cancellation Option Shares previously purchased by Parent, or (iii) any combination thereof, so that Parent's actually realized Total Profit (as defined below) shall not exceed the Maximum Amount after taking into account the foregoing actions. (b) Notwithstanding any other provision of this Agreement, the Stock Option may not be exercised for a number of Option Shares as would, as of the date of the Stock Exercise Notice or Cash Exercise Notice, as applicable, result in a Notional Total Profit (as defined below) of more than the Maximum Amount and, if exercise of the Stock Option otherwise would result in the Notional Total Profit exceeding such amount, Parent, at its discretion, may (in addition to any of the actions specified in Section 11(a) above) increase the Exercise Price for that number of Option Shares set forth in the Stock Exercise Notice or Cash Exercise Notice, as applicable, so that the Notional Total Profit shall not exceed the Maximum Amount; provided, that nothing in this sentence shall restrict any exercise of the Stock Option permitted hereby on any subsequent date at the Exercise Price set forth in Section 2 hereof. (c) As used herein, the term "Total Profit" shall mean the aggregate amount (before taxes) of the following: (i) the cash amount actually received by Parent pursuant to Section 10.5 of the Merger Agreement less any repayment by Parent to the Company pursuant to Section 11(a)(i) hereof, (ii) (x) the net cash amounts or the fair market value of any property received by Parent pursuant to the sale of Option Shares (or of any other securities into or for which such Option Shares are converted or exchanged), less (y) Parent's purchase price for such Option Shares (or other securities) plus (iii) the aggregate amounts received by Parent pursuant to Section 3(d). (d) As used herein, the term "Notional Total Profit" with respect to any number of Option Shares as to which Parent may propose to exercise the Stock Option shall mean the Total Profit determined as of the date of the Stock Exercise Notice or Cash Exercise Notice, as applicable, assuming that the Stock Option was exercised on such date for such number of Option Shares and assuming that such Option Shares, together with all other Option Shares previously acquired upon exercise of the Stock Option and held by Parent and its affiliates as of such date, were sold for cash at the closing price on the NYSE for the Common Stock as of the close of business on the preceding trading day (less customary brokerage commissions).

ANNEX C STOCK OPTION AGREEMENT ---------------------- THIS STOCK OPTION AGREEMENT (this "Agreement"), dated as of October 15, 2000, between Chevron Corporation, a Delaware corporation ("Parent"), and Texaco Inc., a Delaware corporation (the "Company"). W I T N E S S E T H : WHEREAS, Parent and the Company are concurrently with the execution and delivery of this Agreement entering into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which, among other things, Merger Subsidiary will merge with and into the Company on the terms and subject to the conditions stated therein; and WHEREAS, in order to induce the Company to enter into the Merger Agreement and as a condition for the Company's agreeing so to do, Parent has granted to the Company the Stock Option (as hereinafter defined), on the terms and conditions set forth herein; NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth herein and in the Merger Agreement, and for other good and valuable consideration, the adequacy of which is hereby acknowledged, the parties hereto agree as follows: Section 1. Definitions. Capitalized terms used and not defined herein have ----------- the respective meanings assigned to them in the Merger Agreement. Section 2. Grant of Stock Option. --------------------- (a) Parent hereby grants to the Company an irrevocable option (the "Stock Option") to purchase, on the terms and subject to the conditions hereof, for $85.96 per share (the "Exercise Price") in cash, up to 127,000,000 fully paid and non-assessable shares (the "Option Shares") of Parent's common stock, par value $0.75 per share (the "Common Stock"). The Exercise Price and number of Option Shares shall be subject to adjustment as provided in Sections 2(b) and 6 below. (b) In the event that any (i) additional shares of Common Stock are issued or otherwise become outstanding after the date of the Agreement (other than pursuant to this Agreement) or (ii) shares of Common Stock are redeemed, repurchased, retired or otherwise cease to be outstanding after the date of the Agreement, the number of shares of Common Stock subject to the Stock Option shall be increased or decreased, as appropriate, so that after such issuance or redemption, such number equals 19.9% of the number of shares of Common Stock then issued and outstanding (without giving effect to any shares subject or issued pursuant to the Stock Option). Nothing contained in this Section 2(b) or elsewhere in this Agreement shall be deemed to authorize Parent or the Company to breach any provision of the Merger Agreement. C-1

Section 3. Exercise of Stock Option. ------------------------ (a) The Company may, subject to the provisions of this Section, exercise the Stock Option, in whole or in part, at any time or from time to time, after the occurrence of a Parent Trigger Event (defined below) and prior to the Termination Date. "Termination Date" shall mean the earliest of (i) the Effective Time of the Merger, (ii) 90 days after the date full payment contemplated by Section 10.6 of the Merger Agreement is made by Parent to the Company thereunder or (iii) one day after the date of the termination of the Merger Agreement so long as, in the case of this clause (iii), no Parent Trigger Event has occurred or could still occur pursuant to Section 10.6 of the Merger Agreement. Notwithstanding the occurrence of the Termination Date, the Company shall be entitled to purchase Option Shares pursuant to any exercise of the Stock Option, on the terms and subject to the conditions hereof, to the extent the Company exercised the Stock Option prior to the occurrence of the Termination Date. A "Parent Trigger Event" shall mean an event the result of which is that Parent becomes obligated to pay a fee to the Company pursuant to Section 10.6 of the Merger Agreement. (b) The Company may purchase Option Shares pursuant to the Stock Option only if all of the following conditions are satisfied: (i) no preliminary or permanent injunction or other order issued by any federal or state court of competent jurisdiction in the United States shall be in effect prohibiting delivery of the Option Shares, (ii) any applicable waiting period under the HSR Act shall have expired or been terminated, and (iii) any prior notification to or approval of any other regulatory authority in the United States or elsewhere required in connection with such purchase shall have been made or obtained, other than those which if not made or obtained would not reasonably be expected to result in a Material Adverse Effect on Parent and its Subsidiaries, taken as a whole. (c) If the Company shall be entitled to and wishes to exercise the Stock Option, it shall do so by giving Parent written notice (the "Stock Exercise Notice") to such effect, specifying the number of Option Shares to be purchased and a place and closing date not earlier than three business days nor later than 10 business days from the date of such Stock Exercise Notice. If the closing cannot be consummated on such date because any condition to the purchase of Option Shares set forth in Section 3(b) has not been satisfied or as a result of any restriction arising under any applicable law or regulation, the closing shall occur five days (or such earlier time as the Company may specify) after satisfaction of all such conditions and the cessation of all such restrictions; provided that in no event shall the closing of the purchase be postponed by more than nine months after the Termination Date as a result of this clause (c). (d) So long as the Stock Option is exercisable pursuant to the terms of Section 3(a) the Company may elect to send a written notice to Parent (the "Cash Exercise Notice") specifying a date not later than 20 business days and not earlier than 10 business days following the date such notice is given on which date Parent shall pay to the Company in exchange for the cancellation of the relevant portion of the Stock Option an amount in cash equal to the Spread (as hereinafter defined) multiplied by all or such portion of the Option Shares subject to the Stock Option as the Company shall specify. As used herein, "Spread" shall mean the excess, if any, over the Exercise Price of the higher of (x) if applicable, the highest price per share of Common C-2

Stock paid or proposed to be paid by any Person pursuant to any Acquisition Proposal relating to Parent (the "Alternative Exercise Price") or (y) the average of the closing price of the shares of Common Stock on the NYSE at the end of the regular session, as reported on the Consolidated Tape, Network A for the five consecutive trading days ending on and including the trading date immediately preceding the date on which the Cash Exercise Notice is given (the "Average Market Price"). If the Alternative Exercise Price includes any property other than cash, the Alternative Exercise Price shall be the sum of (i) the fixed cash amount, if any, included in the Alternative Exercise Price plus (ii) the fair market value of such other property. If such other property consists of securities with an existing public trading market, the average of the closing prices (or the average of the closing bid and asked prices if closing prices are unavailable) for such securities in their principal public trading market on the five trading days ending five days prior to the date on which the Cash Exercise Notice is given shall be deemed to equal the fair market value of such property. If such other property includes anything other than cash or securities with an existing public trading market, the Alternative Exercise Price shall be deemed to equal the Average Market Price. Upon exercise of its right pursuant to this Section 3(d) and the receipt by the Company of the applicable cash amount with respect to the Option Shares or the applicable portion thereof, the obligations of Parent to deliver Option Shares pursuant to Section 3(e) shall be terminated with respect to the number of Option Shares specified in the Cash Exercise Notice. The Spread shall be appropriately adjusted, if applicable, to give effect to Section 6. (e) (i) At any closing pursuant to Section 3(c) hereof, the Company shall make payment to Parent of the aggregate purchase price for the Option Shares to be purchased and Parent shall deliver to the Company a certificate representing the purchased Option Shares, registered in the name of the Company or its designee and (ii) at any closing pursuant to Section 3(d) hereof, Parent will deliver to the Company cash in an amount determined pursuant to Section 3(d) hereof. Any payment made by the Company to Parent, or by Parent to the Company, pursuant to this Agreement shall be made by wire transfer of immediately available funds to a bank designated by the party receiving such funds, provided that the failure or refusal by Parent to designate such a bank account shall not preclude the Company from exercising the Stock Option. If at the time of the issuance of Option Shares pursuant to the exercise of the Stock Option, Parent Rights or any similar securities are outstanding, then the Option Shares issued pursuant to such exercise shall be accompanied by corresponding Parent Rights or such similar securities. (f) Certificates for Common Stock delivered at the closing described in Section 3(c) hereof shall be endorsed with a restrictive legend which shall read substantially as follows: "The transfer of the shares represented by this certificate is subject to resale restrictions arising under the Securities Act of 1933, as amended. The shares represented by this certificate are also subject to repurchase by the Issuer pursuant to the Stock Option Agreement dated as of October 15, 2000, a copy of which agreement may be obtained upon request from the Issuer." C-3

It is understood and agreed that the above legend shall be removed by delivery of substitute certificate(s) without this reference (i) if the Company shall have delivered to Parent a copy of a no-action letter from the staff of the Securities and Exchange Commission, or a written opinion of counsel, in form and substance reasonably satisfactory to Parent, to the effect that such legend is not required for purposes of, or resale may be effected pursuant to an exemption from registration under, the Securities Act or (ii) in connection with any sale registered under the Securities Act. In addition, these certificates shall bear any other legend as may be required by applicable law. (g) At any time following the exercise by the Company of the Stock Option, Parent shall have the right, within 5 business days after written notice to the Company, to purchase for cash all of the Option Shares received by the Company pursuant to this Agreement at a purchase price per share equal to the higher of (x) the Alternative Exercise Price or (y) the Average Market Price. At any closing pursuant to this Section 3(g), Parent shall make payment to the Company of the aggregate purchase price for the Option Shares to be purchased and the Company shall deliver to Parent a certificate representing the purchased Option Shares. Section 4. Representations and Warranties of Parent. Parent hereby ---------------------------------------- represents and warrants to the Company as follows: (a) Parent is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware. The execution, delivery and performance by Parent of this Agreement and the consummation by Parent of the transactions contemplated hereby (i) are within Parent's corporate powers, (ii) have been duly authorized by all necessary corporate action, (iii) require no action by or in respect of, or filing with, any governmental body, agency or official, except for compliance with any applicable requirements of the HSR Act, the Exchange Act, the Securities Act, and laws, rules and regulations in foreign jurisdictions governing antitrust or merger control matters (iv) assuming compliance with the matters referred to in clause (iii), do not contravene, or constitute a violation of, any provision of applicable law or regulation or of the certificate of incorporation or by-laws of Parent or of any judgment, injunction, order or decree binding upon Parent or any of its Subsidiaries, (v) do not and will not constitute a default under or give rise to a right of termination, cancellation or acceleration of any right or obligation of Parent or any of its Subsidiaries or to a loss of any benefit to which Parent or any of its Subsidiaries is entitled under any provision of any agreement, contract or other instrument binding upon Parent or any of its Subsidiaries or any license, franchise, permit or other similar authorization held by Parent or any of its Subsidiaries, and (vi) do not and will not result in the creation or imposition of any Lien on any asset of Parent or any of its Subsidiaries, except for such contraventions, conflicts or violations referred to in clause (iv) or defaults, rights of termination, cancellation or acceleration, or losses or Liens referred to in clauses (v) and (vi) that would not, individually or in the aggregate, have a Material Adverse Effect on Parent. This Agreement has been duly executed and delivered by Parent and constitutes a valid and binding agreement of Parent. (b) Parent has taken all necessary corporate action to authorize and reserve and to permit it to issue, and at all times from the date hereof until such time as the obligation to deliver C-4

Option Shares upon the exercise of the Stock Option terminates, will have reserved for issuance upon any exercise of the Stock Option, the number of Option Shares subject to the Stock Option (less the number of Option Shares previously issued upon any partial exercise of the Stock Option). All of the Option Shares to be issued pursuant to the Stock Option have been duly authorized and, upon issuance and delivery thereof pursuant to this Agreement, will be duly authorized, validly issued, fully paid and nonassessable, and will be delivered free and clear of all claims, liens, charges, encumbrances and security interests (other than those created by this Agreement). Option Shares issued upon exercise of the Stock Option will not be subject to any preemptive or similar rights. The Board of Directors of Parent has resolved to, and Parent promptly after execution of this Agreement will, take all necessary action to render the Parent Rights Agreement inapplicable to the grant or exercise of the Stock Option and the transactions contemplated hereby. The Board of Directors of Parent has (i) taken all necessary action to render section 203 of the Delaware Law, or any other antitakeover statute or similar statute or regulation inapplicable to the acquisition of the Option Shares pursuant to this Agreement, and (ii) has resolved to, and promptly after the execution of this Agreement will, take all necessary action to render the supermajority voting provisions of Article VII of Parent's Certificate of Incorporation inapplicable to the acquisition of the Option Shares pursuant to this Agreement. Section 5. Representations and Warranties of the Company. The Company --------------------------------------------- hereby represents and warrants to Parent as follows: The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware. The execution, delivery and performance by the Company of this Agreement and the consummation of the transactions contemplated hereby (i) are within the Company's corporate powers and (ii) have been duly authorized by all necessary corporate action. The Option Shares acquired by the Company upon the exercise of the Stock Option will not be, and the Stock Option is not being, acquired by the Company with the intention of making a public distribution thereof. Neither the Stock Option nor the Option Shares acquired upon exercise of the Stock Option will be sold or otherwise disposed of by the Company except in compliance with the Securities Act. This agreement has been duly executed and delivered by the Company and constitutes a valid and binding agreement of the Company. Section 6. Adjustment upon Changes in Capitalization or Merger. --------------------------------------------------- (a) In the event of any change in the outstanding shares of Common Stock by reason of a stock dividend, stock split, reverse stock split, split-up, merger, consolidation, recapitalization, combination, conversion, exchange of shares, extraordinary or liquidating dividend or similar transaction which would affect the Company's rights hereunder, the type and number of shares or securities purchasable upon the exercise of the Stock Option and the Exercise Price shall be adjusted appropriately, and proper provision will be made in the agreements governing such transaction, as shall fully preserve the economic benefits provided hereunder to the Company and the full satisfaction of Parent's obligations hereunder. In no event shall the number of shares of Common Stock subject to the Stock Option exceed 19.9% of the number of shares of Common Stock issued and outstanding at the time of exercise (without giving effect to any shares subject or issued pursuant to the Stock Option). C-5

(b) Without limiting the foregoing, whenever the number of Option Shares purchasable upon exercise of the Stock Option is adjusted as provided in this Section 6, the Exercise Price shall be adjusted by multiplying the Exercise Price by a fraction, the numerator of which is equal to the number of Option Shares purchasable prior to the adjustment and the denominator of which is equal to the number of Option Shares purchasable after the adjustment. (c) Without limiting or altering the parties' rights and obligations under the Merger Agreement, in the event that Parent enters into an agreement (i) to consolidate with or merge into any Person, other than the Company or one of its Subsidiaries, and Parent will not be the continuing or surviving corporation in such consolidation or merger, (ii) to permit any Person, other than the Company or one of its Subsidiaries, to merge into Parent and Parent will be the continuing or surviving corporation, but in connection with such merger, the shares of Common Stock outstanding immediately prior to the consummation of such merger will be changed into or exchanged for stock or other securities of Parent or any other Person or cash or any other property, or the shares of Common Stock outstanding immediately prior to the consummation of such merger will, after such merger, represent less than 50% of the outstanding voting securities of the merged company, or (iii) to sell or otherwise transfer all or substantially all of its assets to any Person, other than the Company or one of its Subsidiaries, then, and in each such case, the agreement governing such transaction will make proper provision so that the Stock Option will, upon the consummation of any such transaction and upon the terms and conditions set forth herein, be converted into, or exchanged for, an option with identical terms appropriately adjusted to acquire the number and class of shares or other securities or property that the Company would have received in respect of Option Shares had the Stock Option been exercised immediately prior to such consolidation, merger, sale or transfer or the record date therefor, as applicable, and shall make any other necessary adjustments. Parent shall take such steps in connection with such consolidation, merger, liquidation or other such transaction as may be reasonably necessary to assure that the provisions hereof shall thereafter apply as nearly as possible to any securities or property thereafter deliverable upon exercise of the Stock Option. Section 7. Further Assurances; Remedies. ---------------------------- (a) Parent agrees to maintain, free from preemptive rights, sufficient authorized but unissued or treasury shares of Common Stock so that the Stock Option may be fully exercised without additional authorization of Common Stock after giving effect to all other options, warrants, convertible securities and other rights of third parties to purchase shares of Common Stock from Parent, and to issue the appropriate number of shares of Common Stock pursuant to the terms of this Agreement. All of the Option Shares to be issued pursuant to the Stock Option, upon issuance and delivery thereof pursuant to this Agreement, will be duly authorized, validly issued, fully paid and non-assessable, and will be delivered free and clear of all claims, liens, charges, encumbrances and security interests (other than those created by this Agreement). (b) Parent agrees not to avoid or seek to avoid (whether by charter amendment or through reorganization, consolidation, merger, issuance of rights, dissolution or sale of assets, or by any other voluntary act) the observance or performance of any of the covenants, agreements or conditions to be observed or performed hereunder by Parent. C-6

(c) Parent agrees that promptly after the occurrence of a Parent Trigger Event it shall take all actions as may from time to time be required (including (i) complying with all applicable premerger notification, reporting and waiting period requirements under the HSR Act and (ii) in the event that prior notification to or approval of any other regulatory authority in the United States or elsewhere is necessary before the Stock Option may be exercised, complying with its obligations thereunder and cooperating with the Company in preparing and processing the required notices or applications) in order to permit the Company to exercise the Stock Option and purchase Option Shares pursuant to such exercise. (d) The parties agree that the Company would be irreparably damaged if for any reason Parent failed to issue any of the Option Shares (or other securities or property deliverable pursuant to Section 6 hereof) upon exercise of the Stock Option or to perform any of its other obligations under this Agreement, and that the Company would not have an adequate remedy at law for money damages in such event. Accordingly, the Company shall be entitled to specific performance and injunctive and other equitable relief to enforce the performance of this Agreement by Parent. Accordingly, if the Company should institute an action or proceeding seeking specific enforcement of the provisions hereof, Parent hereby waives the claim or defense that Parent has an adequate remedy at law and hereby agrees not to assert in any such action or proceeding the claim or defense that such a remedy at law exists. Parent further agrees to waive any requirements for the securing or posting of any bond in connection with obtaining any such equitable relief. This provision is without prejudice to any other rights that the Company may have against Parent for any failure to perform its obligations under this Agreement. Section 8. Listing of Option Shares. Promptly after the occurrence of a ------------------------ Parent Trigger Event and from time to time thereafter if necessary, Parent will apply to list all of the Option Shares subject to the Stock Option on the NYSE and will use its reasonable best efforts to obtain approval of such listing as soon as practicable. Section 9. Registration of the Option Shares. --------------------------------- (a) If, within two years of the exercise of the Stock Option, the Company requests Parent in writing to register under the Securities Act any of the Option Shares received by the Company hereunder, Parent will use its reasonable best efforts to cause the offering of the Option Shares so specified in such request to be registered as soon as practicable so as to permit the sale or other distribution by the Company of the Option Shares specified in its request (and to keep such registration in effect for a period of at least 90 days), and in connection therewith Parent shall prepare and file as promptly as reasonably possible (but in no event later than 60 days from receipt of the Company's request) a registration statement under the Securities Act to effect such registration on an appropriate form, which would permit the sale of the Option Shares by the Company in accordance with the plan of disposition specified by the Company in its request. Parent shall not be obligated to make effective more than two registration statements pursuant to the foregoing sentence; provided, however, that Parent may postpone the filing of a registration statement relating to a registration request by the Company under this Section 9 for a period of time (not in excess of 90 days) if in Parent's reasonable, good faith judgment (i) such filing would require the disclosure of material information that Parent has a bona fide business purpose C-7

for preserving as confidential or (ii) the sale of Option Shares by the Company would materially interfere with any pending or anticipated acquisition, financing or transaction involving Parent or its Subsidiaries (but in no event shall Parent exercise such postponement right more than once in any twelve-month period). (b) Parent shall notify the Company in writing not less than 10 days prior to filing a registration statement under the Securities Act (other than a filing on Form S-4 or S-8 or any successor form) with respect to any shares of Common Stock. If the Company wishes to have any portion of its Option Shares included in such registration, it shall advise Parent in writing to that effect within two business days following receipt of such notice, and Parent will thereupon include the number of Option Shares indicated by the Company in such registration; provided that if the managing underwriter(s) of the offering pursuant to such registration statement advise Parent that in their opinion the number of shares of Common Stock requested to be included in such registration exceeds the number which can be sold in such offering, Parent shall only include in such registration such number or dollar amount of Option Shares which, in the good faith opinion of the managing underwriter(s), can be sold without materially and adversely affecting such offering. (c) All expenses relating to or in connection with any registration contemplated under this Section 9 and the transactions contemplated thereby (including all filing, printing, reasonable professional, roadshow and other fees and expenses relating thereto) will be at Parent's expense except for underwriting discounts or commissions and brokers' fees. The Company and Parent agree to enter into a customary underwriting agreement with underwriters upon such terms and conditions as are customarily contained in underwriting agreements with respect to secondary distributions. Parent shall indemnify the Company, its officers, directors, agents, other controlling persons and any underwriters retained by the Company in connection with such sale of such Option Shares in the customary way, and shall agree to customary contribution provisions with such persons, with respect to claims, damages, losses and liabilities (and any expenses relating thereto) arising (or to which the Company, its officers, directors, agents, other controlling persons or underwriters may be subject) in connection with any such offer or sale under the federal securities laws or otherwise, except for information furnished in writing by the Company or its underwriters to Parent. The Company and its underwriters, respectively, shall indemnify Parent to the same extent with respect to information furnished in writing to Parent by the Company and such underwriters, respectively. Section 10. Miscellaneous. ------------- (a) Extension of Exercise Periods. The periods during which the Company ----------------------------- may exercise its rights under Sections 2 and 3 hereof, or Parent may exercise its rights under Section 2(g), shall be extended in each such case at the request of the Company to the extent necessary to avoid liability by the Company under Section 16(b) of the Exchange Act by reason of such exercise. (b) Amendments; Entire Agreement. This Agreement may not be modified, ---------------------------- amended, altered or supplemented, except upon the execution and delivery of a written C-8

agreement executed by the parties hereto. This Agreement, together with the Merger Agreement (including any exhibits and schedules thereto), contains the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior and contemporaneous agreements and understandings, oral or written, with respect to such transactions.

Section 11. Profit Limitation. ----------------- (a) Notwithstanding any other provision of this Agreement or the Merger Agreement, in no event shall the Company's Total Profit (as defined below) exceed $1,100,000,000 (the "Maximum Amount") and, if it otherwise would exceed such Maximum Amount, the Company at its sole election may (i) pay cash to Parent, (ii) deliver to Parent for cancellation Option Shares previously purchased by the Company, or (iii) any combination thereof, so that the Company's actually realized Total Profit (as defined below) shall not exceed the Maximum Amount after taking into account the foregoing actions. (b) Notwithstanding any other provision of this Agreement, the Stock Option may not be exercised for a number of Option Shares as would, as of the date of the Stock Exercise Notice or Cash Exercise Notice, as applicable, result in a Notional Total Profit (as defined below) of more than the Maximum Amount and, if exercise of the Stock Option otherwise would result in the Notional Total Profit exceeding such amount, the Company, at its discretion, may (in addition to any of the actions specified in Section 11(a) above) increase the Exercise Price for that number of Option Shares set forth in the Stock Exercise Notice or Cash Exercise Notice, as applicable, so that the Notional Total Profit shall not exceed the Maximum Amount; provided, that nothing in this sentence shall restrict any exercise of the Stock Option permitted hereby on any subsequent date at the Exercise Price set forth in Section 2 hereof. (c) As used herein, the term "Total Profit" shall mean the aggregate amount (before taxes) of the following: (i) the cash amount actually received by the Company pursuant to Section 10.6 of the Merger Agreement less any repayment by the Company to Parent pursuant to Section 11(a)(i) hereof, (ii) (x) the net cash amounts or the fair market value of any property received by the Company pursuant to the sale of Option Shares (or of any other securities into or for which such Option Shares are converted or exchanged), less (y) the Company's purchase price for such Option Shares (or other securities) plus (iii) the aggregate amounts received by the Company pursuant to Section 3(d). (d) As used herein, the term "Notional Total Profit" with respect to any number of Option Shares as to which the Company may propose to exercise the Stock Option shall mean the Total Profit determined as of the date of the Stock Exercise Notice or Cash Exercise Notice, as applicable, assuming that the Stock Option was exercised on such date for such number of Option Shares and assuming that such Option Shares, together with all other Option Shares previously acquired upon exercise of the Stock Option and held by the Company and its affiliates as of such date, were sold for cash at the closing price on the NYSE for the Common Stock as of the close of business on the preceding trading day (less customary brokerage commissions).

ANNEX D LEHMAN BROTHERS October 15, 2000 Board of Directors Chevron Corporation 575 Market Street San Francisco, CA 94105 Members of the Board: We understand that Chevron Corporation ("Chevron" or the "Company") and Texaco Inc. ("Texaco") are considering entering into a transaction pursuant to which, among other things, (i) Texaco will merge with a newly formed subsidiary of Chevron ("Merger Sub"), with Texaco being the surviving corporation (the "Merger"); and (ii) upon the effectiveness of the Merger, each share of common stock of Texaco issued and outstanding prior to the Merger will be converted into the right to receive 0.77 shares of the common stock of Chevron (the "Exchange Ratio"). We further understand that the Merger is subject to the condition that it qualify for pooling-of-interests accounting treatment. The terms and conditions of the Merger are set forth in more detail in an Agreement and Plan of Merger to be entered into among Chevron, Texaco and Merger Sub (the "Agreement"). We have been requested by the Board of Directors of Chevron to render our opinion with respect to the fairness, from a financial point of view, to the Company, of the Exchange Ratio to be paid to Texaco's stockholders in the Merger. We have not been requested to opine as to, and our opinion does not in any manner address, the Company's underlying business decision to proceed with or effect the Merger. In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and specific terms of the Merger; (2) publicly available information concerning Chevron and Texaco that we believe to be relevant to our analysis, including Annual Reports on Form 10-K for the fiscal year ended December 31, 1999 and Quarterly Reports on Form 10-Q for the quarters ended March 31 and June 30, 2000; (3) financial and operating information with respect to the business, operations and prospects of Chevron furnished to us by Chevron, including the amounts and timing of the cost savings and operating synergies which management of Chevron estimates will result from a combination of the businesses of Chevron and Texaco (the "Expected Synergies); (4) the trading histories of Chevron's common stock and Texaco's common stock from September 22, 1999 to the present and a comparison of these trading histories with each other and with those of other companies that we deemed relevant; (5) a comparison of the historical financial results and present financial condition of each of Chevron and Texaco with each other and with those of other companies that we deemed relevant; (6) a comparison of the financial terms of the Merger with the financial terms of certain other transactions that we deemed D-1

relevant; (7) the potential pro forma impact of the Merger on the future financial performance of Chevron (including the Expected Synergies); (8) the relative contributions of Chevron and Texaco to the historical and future financial performance of the combined company on a pro forma basis; and (9) the pro forma impact on the combined company of the potential divestiture of Texaco's two domestic downstream businesses in connection with the Merger. In addition, we have had discussions with the managements of Texaco and the Company concerning their respective businesses, operations, assets, financial conditions and prospects and have undertaken such other studies, analyses and investigations as we deemed appropriate. In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without assuming any responsibility for independent verification of such information and, with respect to information regarding Chevron, have further relied upon the assurances of management of Chevron that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. In arriving at our opinion, we have not used any financial forecasts or business plans of Chevron or Texaco prepared by management of Chevron or Texaco. Accordingly, with the consent of Chevron, we have assumed that the published estimates of third party research analysts are a reasonable basis upon which to evaluate the future financial performance of Chevron and Texaco and that Chevron and Texaco will perform substantially in accordance with such estimates. Upon advice of Chevron, we also have assumed that the amounts and timing of the Expected Synergies are reasonable and that the Expected Synergies will be realized substantially in accordance with such estimates. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of Chevron or Texaco and have not made or obtained any evaluations or appraisals of specific assets or liabilities of Chevron or Texaco. Upon the advice of Chevron and its legal and accounting advisors, we have assumed that the Merger will qualify (i) for pooling-of-interests accounting treatment and (ii) as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and therefore as a tax-free transaction to the stockholders of Texaco. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter. Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the Exchange Ratio to be paid by the Company in the Merger is fair to the Company. We have acted as financial advisor to Chevron in connection with the Merger and will receive a fee for our services which is contingent upon the consummation of the Merger. In addition, the Company has agreed to indemnify us for certain liabilities that may arise out of the rendering of this opinion. We also have performed various investment banking services for the Company in the past and have received customary fees for such services. In the ordinary course of our business, we actively trade in the debt and equity securities of the Company and Texaco for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities. This opinion is for the use and benefit of the Board of Directors of Chevron and is D-2

rendered to the Board of Directors in connection with its consideration of the Merger. This opinion is not intended to be and does not constitute a recommendation to any stockholder of Chevron as to how such stockholder should vote with respect to the Merger. Very truly yours, /S/ LEHMAN BROTHERS D-3

("Texaco"), Chevron Corporation ("Chevron") and Keepep Inc., a wholly owned subsidiary of Chevron ("Merger Sub"). The Merger Agreement provides for, among other things, the merger of Merger Sub with and into Texaco (the "Merger") pursuant to which each outstanding share of the common stock, par value $3.125 per share of Texaco ("Texaco Common Stock") will be converted into the right to receive 0.77 (the "Exchange Ratio") of a share of the common stock, par value $0.75 per share, of Chevron ("Chevron Common Stock"). As a result of the Merger, Texaco will become a wholly owned subsidiary of Chevron. In arriving at our opinion, we have reviewed the Merger Agreement and certain related documents, and certain publicly available business and financial information relating to Texaco and Chevron. We have also reviewed certain other information relating to Texaco and Chevron, including financial forecasts, provided to or discussed with us by Texaco and Chevron, and have met with the managements of Texaco and Chevron to discuss the business and prospects of Texaco and Chevron. We have also considered certain financial and stock market data of Texaco and Chevron, and we have compared those data with similar data for other publicly held companies in businesses similar to Texaco and Chevron, and we have considered, to the extent publicly available, the financial terms of certain other business combinations and other transactions which have recently been effected. We also considered such other information, financial studies, analyses and investigations and financial, economic and market criteria which we deemed relevant. In connection with our review, we have not assumed any responsibility for independent verification of any of the foregoing information and have relied on such information being complete and accurate in all material respects. With respect to the financial forecasts, we have been advised, and have assumed, that such forecasts have been reasonably prepared on bases E-1

reflecting the best currently available estimates and judgments of the managements of Texaco and Chevron as to the future financial performance of Texaco and Chevron and the potential synergies (including the amount, timing and achievability thereof) anticipated to result from the Merger. We have also assumed, with your consent, that the Merger will be consummated in accordance with the terms of the Merger Agreement without waiver of any condition to the Merger. We also have assumed, with your consent, that the Merger will be accounted for as a pooling of interests in accordance with generally accepted accounting principles and will qualify as a tax-free reorganization for U.S. federal income tax purposes. We have further assumed, with your consent, that in the course of obtaining the necessary regulatory and third-party consents for the proposed Merger and the transactions contemplated by the Merger Agreement, no delay or restriction will result or be imposed that will have a material effect on the expected benefits of the proposed Merger to the holders of Texaco Common Stock. In addition, we have not been requested to make, and have not made, an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of Texaco or Chevron, nor have we been furnished with any such evaluations or appraisals. Our opinion is necessarily based upon information available to us, and financial, economic, market and other conditions as they exist and can be evaluated, on the date hereof. We are not expressing any opinion as to the actual value of the Chevron Common Stock when issued pursuant to the Merger or the prices at which the Chevron Common Stock will trade subsequent to the Merger. In connection with our engagement, we were not requested to, and did not, solicit third-party indications of interest in the possible acquisition of all or part of Texaco. We have been advised that the Exchange Ratio was determined through arms' length negotiations between the parties. We have acted as financial advisor to Texaco in connection with the Merger and will receive a fee for our services, a significant portion of which is contingent upon the consummation of the Merger. We and our affiliates have in the past provided financial services to Texaco and certain of its affiliates and to Chevron and certain of its affiliates unrelated to the proposed Merger for which services we have received compensation, and are currently providing financial services to Texaco and certain of its affiliates with regard to matters arising out of but unrelated to the proposed Merger. In the ordinary course of business, we and our affiliates may actively trade the debt and equity securities of both Texaco and Chevron for our and their own accounts and for the accounts of customers and, accordingly, may at any time hold long or short positions in such securities. It is understood that this letter is for the information of the Board of Directors of Texaco in connection with its evaluation of the Merger and does not constitute a recommendation to any stockholder as to how such stockholder should vote or act on any matter relating to the Merger. E-2

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio is fair from a financial point of view to the holders of Texaco Common Stock. Very truly yours, /S/ CREDIT SUISSE FIRST BOSTON CORPORATION E-3

PART II INFORMATION NOT REQUIRED IN PROSPECTUS ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS Section 145 of the Delaware General Corporation Law ("Delaware Law") permits Chevron's board of directors to indemnify any person against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with any threatened, pending or completed action, suit or proceeding in which such person is made a party by reason of his or her being or having been a director, officer, employee or agent of Chevron, or serving or having served, at the request of Chevron, as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act. The statute provides that indemnification pursuant to its provisions is not exclusive of other rights of indemnification to which a person may be entitled under any by law, agreement, vote of stockholders or disinterested directors, or otherwise. Article IX of Chevron's Restated Certificate of Incorporation (the "Chevron Certificate") provides for indemnification of its directors, officers, employees and other agents to the fullest extent permitted by law. As permitted by sections 102 and 145 of Delaware Law, the Chevron Certificate eliminates the liability of a Chevron director for monetary damages to Chevron and its stockholders arising from a breach or alleged breach of a director's fiduciary duty except for liability under section 174 of Delaware Law or liability for any breach of the director's duty of loyalty to Chevron or its stockholders, for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law or for any transaction from which the director derived an improper personal benefit. In addition, Chevron maintains officers' and directors' insurance covering certain liabilities that may be incurred by officers and directors in the performance of their duties. ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES (a) Exhibits. See Exhibit Index for the list of exhibits at page II-4 of this registration statement, which is incorporated herein by reference. (b) Financial Statement Schedules. [None] ITEM 22. UNDERTAKINGS The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Exchange Act that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. II-1

The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form. The registrant undertakes that every prospectus (1) that is filed pursuant to the paragraph immediately preceding, or (2) that purports to meet the requirements of section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415 of the Securities Act, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. The registrant hereby undertakes to respond to requests for information that is incorporated by reference into the proxy statement/prospectus which forms a part of this registration statement pursuant to Items 4, 10(b), 11, or 13 of this registration statement, within one business day of receipt of such request, and to send the incorporated documents by first-class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of this registration statement through the date of responding to the request. The registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.

         Re:      Registration Statement on Form S-4 (File Number 333-54240)


Ladies and Gentlemen:

     We are acting as counsel for Chevron Corporation, a Delaware corporation
("Chevron"), in connection with the registration under the Securities Act of
1933, as amended, of: (a) the shares of common stock, par value $0.75 per share,
of Chevron, all of which are authorized but heretofore unissued shares, issuable
to holders of common stock, par value $3.125 per share, of Texaco Inc., a
Delaware corporation ("Texaco"), pursuant to an Agreement and Plan of Merger,
dated as of October 15, 2000 (the "Merger Agreement"), by and among Chevron,
Keepep Inc., a Delaware corporation and wholly-owned subsidiary of Chevron, and
Texaco and (b) the Chevron Preferred Stock Purchase Rights that will be attached
to and represented by the certificates issued for shares of Chevron's common
stock (which Preferred Stock Purchase Rights have no market value independent of
Chevron's common stock, to which they are attached). In this regard we have
participated in the preparation of a Registration Statement on Form S-4 relating
to such shares of Common Stock. Such Registration Statement, as amended, and
including any registration statement related thereto and filed pursuant to Rule
462(b) under the Securities Act (a "Rule 462(b) registration statement") is
herein referred to as the "Registration Statement."

     We are of the opinion that the shares of common stock to be issued by the
Company (including any shares of common stock registered pursuant to a Rule
462(b) registration statement) have been duly authorized and, when issued and
delivered pursuant to the terms of the Merger Agreement, will be legally issued,
fully paid and nonassessable.

     We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement and to the use of our name under the caption "Legal
Matters" in the Registration Statement and in the Proxy Statement/Prospectus
included therein.

                                                     Very truly yours,

     In this capacity, we have participated in the preparation of a registration
statement on Form S-4 filed with the Securities Exchange Commission on ________,
2001, pursuant to the Securities Act of 1933, as amended, and the Securities
Exchange Act of 1934, as amended, including the Joint Proxy Statement/Prospectus
of Chevron and Texaco, dated ______, 2001 (the "Proxy Statement"). We have
examined the Merger Agreement, the Proxy Statement, the representation letters
of Chevron and Texaco, both dated ______, 2001, which have been delivered to us
for purposes of this opinion (the "Officers' Certificates"), and such other
documents and corporate records as we have deemed necessary or appropriate for
purposes of this opinion. In addition, we have assumed with your consent that
(i) the merger of Keepep with and into Texaco (the "Merger") will be consummated
in the manner contemplated in the Proxy Statement and in accordance with the
provisions of the Merger Agreement, (ii) the statements concerning the Merger
set forth in the Proxy Statement and the other documents referred to herein are
and, as of the effective time of the Merger, will be, true, accurate, and
complete, (iii) the representations and other statements set forth in each of
the Officer's Certificates are and, as of the effective time of the Merger, will
be, true, accurate, and complete, (iv) any representation or other statement in
the Officers' Certificates or the other documents referred to herein made "to
the best of the knowledge" or similarly qualified is and, at the effective time
of the Merger, will be, in each case, correct without such qualification, (v) no
actions have been (or will be) taken that are inconsistent with any
representation or other statement contained in the Officers' Certificates, and
(vi) original documents (including signatures) are authentic, documents
submitted to us as copies conform to the original documents, and there has been
(or will be, by the effective time of the Merger) due execution and delivery of
all documents where due execution and delivery are prerequisites to the
effectiveness thereof. Other than obtaining the representations set forth in the
Officers' Certificates, we have not independently verified any factual matters
in connection with, or apart from, our preparation of this opinion. Accordingly,
our opinion does not take into account any matters not set forth herein that
might have been disclosed by independent verification. In the course of
preparing our opinion, nothing has come to our attention that would lead us to
believe that any of the facts, representations or other information on which we
have relied in rendering


Chevron Corporation ________, 2001 Page 2 our opinion is incorrect. Based on the foregoing, and subject to the assumptions, exceptions, limitations, and qualifications set forth herein, it is our opinion that the Merger will qualify as a reorganization described in Section 368(a) of the Internal Revenue Code of 1986, as amended. You have not requested, and we do not express, an opinion concerning the particular tax consequences of the Merger or any other transactions contemplated by the Merger Agreement. This opinion expresses our views only as to U.S. federal income tax laws in effect as of the date hereof. It represents our best legal judgment as to the matters addressed herein, but is not binding on the Internal Revenue Service or the courts. Accordingly, no assurance can be given that this opinion, if contested, would be sustained by a court. Furthermore, the authorities on which we rely are subject to change either prospectively or retroactively, and any such change, or any variation or difference in the facts from those on which we rely and assume as correct, as set forth above, might affect the conclusions stated herein. Nevertheless, by rendering this opinion, we undertake no responsibility to advise you of any changes or new developments in U.S. federal income tax laws or the application or interpretation thereof. We consent to the filing of this opinion as an exhibit to the Proxy Statement and to the use of our name under the headings "THE MERGER - Material Federal Income Tax Consequences of the Merger" and "LEGAL MATTERS" in the Proxy Statement. In giving this consent, we do not concede that we are experts within the meaning of the Securities Act of 1933, as amended, or the rules and regulations thereunder, or that this consent is required by Section 7 of the Securities Act of 1933, as amended. This opinion is intended solely for your use and may not be relied on by any other person without our express written permission. Very truly yours, McDermott, Will & Emery

In addition, our opinion does not address any non-income tax or any foreign, state or local tax consequences of the Merger.
