Table of Contents

Q:	What am I voting on?
A:	Chevron is proposing to acquire Unocal. You are being asked to vote to approve and adopt an agreement and plan of merger through which Unocal will merge with and into a wholly owned subsidiary of Chevron, sometimes referred to as “Merger Sub.” After the merger, Merger Sub will be the surviving entity and a wholly owned subsidiary of Chevron, and Unocal will no longer be a separate company.
Q:	What will I receive in exchange for my Unocal shares?
A:	You may elect to receive, for each Unocal common share that you own, either:

•	a combination of 0.7725 of a share of Chevron common stock and $16.25 in cash,
•	1.03 shares of Chevron common stock or
•	$65 in cash.

	Unless you make an all-cash or an all-stock election, you will receive the mixed consideration in the merger. In addition, the all-cash and all-stock elections are subject to proration in order to preserve an overall mix of 0.7725 of a share of Chevron common stock and $16.25 in cash for all of the outstanding shares of Unocal common stock taken together.
	If you are a participant in the Unocal Savings Plan, the Molycorp, Inc. 401(k) Retirement Savings Plan or the Pure Resources 401(k) and Matching Plan (which we collectively refer to in the proxy statement as the Unocal Plans), you will receive instructions from the relevant plan trustee on how to elect to have cash consideration or share consideration allocated to your plan account in exchange for Unocal common stock in your plan account. See “Information About the Special Meeting and Voting — Voting and Elections by Participants in the Unocal Plans” beginning on page 72 for detailed instructions.
	Unocal Plan holders may be subject to an election deadline earlier than the general deadline of the date of the Unocal special meeting. Therefore, you should carefully read any materials you receive from your broker or the relevant plan trustee or administrator.
Q:	Will I be taxed on the consideration that I receive in exchange for my Unocal shares?
A:	The transaction is intended to be tax-free to Unocal stockholders for U.S. federal income tax purposes, except with respect to any cash received. See “The Merger — Material Federal Income Tax Consequences of the Merger” beginning on page 34 of this proxy statement/prospectus.
Q:	What is the required vote to approve and adopt the merger agreement and the merger?
A:	The holders of a majority of the outstanding shares of Unocal common stock as of June 29, the record date for the special meeting, must vote to approve and adopt the merger agreement in order for the merger to be completed. Abstentions from voting and “broker non-votes” are not considered affirmative votes and therefore will have the same practical effect as a vote against the merger.

Q:	What does the Unocal board of directors recommend?
A:	The board of directors of Unocal unanimously recommends that Unocal’s stockholders vote in favor of the merger and any adjournment of the special meeting.
Q:	Do I have dissenters’ or appraisal rights with respect to the merger?
A:	Yes. Under Delaware law, you have the right to dissent from the merger and, in lieu of receiving the merger consideration, obtain payment in cash of the fair value of your shares of Unocal common stock as determined by the Delaware Chancery Court. To exercise appraisal rights, you must strictly follow the procedures prescribed by Delaware law. These procedures are summarized under “The Merger — Appraisal Rights” beginning on page 37 of this proxy statement/prospectus. In addition, the text of the applicable provisions of Delaware law is included as Annex C to this proxy statement/prospectus.

Q:	May I submit a form of election if I vote against the merger?
A:	Yes. You may submit a form of election even if you vote against adopting the merger agreement. However, if you submit a properly executed election form, you will thereby withdraw any previously filed written demand for appraisal and will not be entitled to appraisal rights. See “The Merger — Appraisal Rights” beginning on page 37 of this proxy statement/prospectus.
Q:	When do you expect the merger to occur?
A:	We expect to complete the merger promptly after Unocal stockholders approve and adopt the merger agreement and the merger at the special meeting and after the satisfaction or waiver of all other conditions to the merger. We currently expect this to occur sometime this year.

Q:	When and where is the Unocal special stockholder meeting?
A:	The Unocal special stockholder meeting will take place on [                    ], 2005, at [                    ], Pacific Daylight Time, and will be held at [                    ].
Q:	Who is entitled to vote at the special meeting?
	Holders of record of Unocal common stock at the close of business on June 29, 2005, which is the date Unocal’s board of directors has fixed as the record date for the special meeting, are entitled to vote at the special meeting.
Q:	What do I need to do now?
A:	Please mail your signed proxy card in the enclosed return envelope or vote by telephone or the Internet, as soon as possible, so your shares will be represented at the special meeting. In order to be sure that your vote is counted, please submit your proxy as instructed on your proxy card even if you plan to attend the special meeting in person.

Q:	May I change my vote after I have mailed my signed proxy card?
A:	Yes. You may change your vote at any time before your proxy is voted at the special meeting. If your shares of Unocal common stock are registered in your own name, you can do this in one of three ways.

•	First, you can deliver to Unocal prior to the special meeting a written notice stating that you want to revoke your proxy. The notice should be sent to the attention of the Corporate Secretary, 2141 Rosecrans Avenue, Suite 4000, El Segundo, CA 90245, to arrive by the close of business on [          ], 2005.
•	Second, you can complete and deliver prior to the special meeting a new proxy card. The proxy card should be sent to the addressee indicated on the pre-addressed envelope enclosed with your initial proxy card to arrive by the close of business on [          ], 2005. The latest dated and signed proxy actually received by this addressee before the special meeting will be counted, and any earlier proxies will be considered revoked.

	If you vote your proxy electronically through the Internet or by telephone, you can change your vote by submitting a different vote through the Internet or by telephone, in which case your later-submitted proxy will be recorded and your earlier proxy revoked.

•	Third, you can attend the Unocal special meeting and vote in person. Simply attending the meeting, however, will not revoke your proxy, as you must vote at the special meeting in order to revoke a prior proxy.

	If you are a street-name stockholder and you vote by proxy, you may later revoke your proxy

	instructions by informing the holder of record in accordance with that entity’s procedures.

Q:	If I beneficially own Unocal shares held pursuant to a Unocal Plan, will I be able to vote on adoption of the merger agreement?
A:	Yes. If you are a participant in a Unocal Plan, please submit the voting form you receive from the plan adminis-trator or trustee to indicate to the relevant plan administrator or trustee how you want the Unocal common stock allocated to your plan account to be voted.
Q:	If my shares are held in “street name” by my broker, will my broker vote my shares for me?
A:	If you do not provide your broker with instructions on how to vote your “street name” shares, your broker will not be permitted to vote them on the merger. Therefore, you should be sure to provide your broker with instructions on how to vote your shares. Please check the voting form used by your broker to see if it offers telephone or Internet voting.
Q:	Why is it important for me to vote?
A:	We cannot complete the merger without Unocal stockholders voting in favor of the merger.
Q:	What if I don’t vote?
A:	If you do not give voting instructions to your broker or you do not vote, you will, in effect, be voting against the merger.
Q:	Should I send in my stock certificates with my proxy card?
A:	No. Please do not send your stock certificates with your proxy card. Prior to the election deadline described in this proxy statement/ prospectus, you should send your Unocal common stock certificates to the exchange agent, together with a completed, signed election form being provided to you with this document, or, if your shares are held in “street name,” according to your broker’s instructions.

Q:	How do I elect the type of the merger consideration that I prefer to receive?
A:	Each Unocal stockholder is being sent an election form and transmittal materials. You must properly complete and deliver to the exchange agent the election materials, together with your stock certificates (or a properly completed notice of guaranteed delivery). A return envelope will be enclosed for submitting the election form and certificates to the exchange agent. This is different from the envelope that you will use to return your completed proxy card. Please do not send your stock certificates or form of election with your proxy card.

Q:	Can I make one election for some of my shares and another election for the rest?
A:	Yes. The election form permits you to specify, among the shares you are submitting, how many you are allocating to

•	a mixed election,
•	an all-stock election,

3

---

Table of Contents

•	an all-cash election or
•	no election.

Q:	What if I do not make an election?
A:	If you do not submit a properly completed and signed election form to the exchange agent by the election deadline (or if you submit a properly completed election form indicating no election, together with the certificates representing all of your shares), then you will be deemed to have made the mixed election and would therefore receive $16.25 in cash and 0.7725 of a share of Chevron common stock in exchange for each of your shares of Unocal common stock.
Q:	Can I change my election after I submit an election form?
A:	Yes. You may revoke your election of merger consideration with respect to all or a portion of your shares of Unocal common stock by delivering written notice of your revocation to the exchange agent prior to the election deadline. If you instructed a broker to submit an election for your shares, you must follow your broker’s directions for changing those instructions. In addition, any election of merger consideration you make will automatically be revoked if the merger agreement is terminated.

Q:	Where can I find more information about Unocal and Chevron?
A:	You can find more information about Unocal and Chevron from various sources described under the heading “Additional Information for Stockholders — Where You Can Find More Information” beginning on page 81 of this proxy statement/prospectus.
Q:	Who do I call if I have questions about the meeting or the merger?
A:	If you have any questions about the merger or if you need additional copies of this proxy statement/ prospectus or the enclosed proxy card, you should contact:

	If you need an additional election form, you should contact the exchange agent:

	•	the board’s familiarity with, and understanding of, Unocal’s business, financial condition, results of operations, current business strategy and earnings and prospects and of Chevron’s business, financial condition, results of operations, business strategy and earnings (including the report of Unocal’s management and financial advisor on the results of their due diligence review of Chevron);
	•	the board’s understanding of the current and prospective markets in which Unocal operates, including global, national and local economic conditions, the competitive landscape for oil and gas industry participants generally and the likely effect of these factors on Unocal in light of, and in the absence of, the merger;
	•	the board’s understanding, and management’s review, of Unocal’s current and prospective holdings, including Unocal’s international and deepwater assets, and the board’s and management’s views concerning maximizing the future benefits relating to these holdings in view of Unocal’s size and position in the oil and gas industry. In this regard, Unocal’s board and management believe that:

	–	maximizing Unocal’s unique international asset base would require very significant capital outlays and the assumption of a degree of risk and potential volatility in the results of the business that in each case would be borne significantly more readily if the company were larger and more diversified; and
	–	by virtue of its financial and technical resources and geographic scope, Chevron would be better positioned, and therefore more likely, to develop these prospects without subjecting Chevron to the same degree of volatility;

	•	management’s review, and the board’s understanding, of the geopolitical risks inherent in Unocal’s asset portfolio, and of the likelihood that a business combination with Chevron would diversify these risks significantly. In this regard, the board noted that on a barrels of oil-equivalent basis, as of December 31, 2004, approximately 67 percent of Unocal’s oil and gas production and approximately 74 percent of Unocal’s proved oil and gas reserves were located outside the United States;
	•	the fact that, because most of the merger consideration is payable in the form of Chevron shares, Unocal stockholders will have the opportunity to participate in the performance of the combined post-merger company. In that regard, the Unocal board understood that the volatility of prices for oil and gas would cause the value of the merger consideration to fluctuate, perhaps significantly, but

		was of the view that on a long-term basis it would be desirable for stockholders to have an opportunity to retain some continuing investment in the post-merger combined company. Unocal’s board and management noted that the combined company was expected to be highly competitive across all key aspects of the energy sector and would benefit from the integration of Unocal’s and Chevron’s complementary businesses and strategies and from the combined expertise of each company’s personnel. The board noted specifically the strengthening of the combined company’s operations in the following core geographic areas:

	–	the Asia-Pacific region, where, after the merger, Chevron is expected to be in the top tier of natural gas producers and marketers, the top oil and gas producer in Thailand and will have an enhanced presence in key areas such as Indonesia;
	–	the Gulf of Mexico, where, after the merger, Chevron is expected to have an enhanced position in terms of available assets and deepwater opportunities;
	–	the Caspian Region, where the acquisition will give Chevron the second-largest interest in oil producing operations in the Azerbaijan International Operating Company and will broaden Chevron’s status as a leading oil company in that region.

	–	maintaining focus on high-impact exploration and growth and leveraging Unocal’s advantaged positions in the Gulf of Thailand and deepwater Indonesia;
	–	building large-scale businesses in Asia and pursuing regional expansion in Asia in general;
	–	continuing exploration and development efforts in the Gulf of Mexico deepwater; and
	–	the greater likelihood of pursuing these strategies effectively, in light of the market conditions and the oil and gas industry landscape, if the companies were combined;

	•	the board’s belief, supported by the views and information provided by Unocal’s management and financial advisor, that Unocal’s stock price following the publication in early 2005 of news reports relating to a potential transaction (see “— Background of the Merger”) reflected, in part, takeover speculation and therefore was higher than Unocal’s unaffected trading price, and that the consideration offered by Chevron in the merger represented a premium to the unaffected trading price of Unocal common stock;
	•	the board’s understanding, and management’s review, of overall market conditions, including then-current and prospective commodity prices and Unocal’s unaffected trading price, and the board’s determination that, in light of these factors, the timing of a potential transaction was favorable to Unocal;
	•	the fact that the dividend yield of Chevron common stock is considerably higher than that of Unocal, and the board’s expectation that Unocal stockholders who receive Chevron common stock in the merger would receive higher annual dividends than the dividends paid with respect to Unocal’s common stock;
	•	the potential savings from operational synergies and reduced corporate expenses, currently estimated by Chevron to be approximately $325 million before tax annually, and the related potential impact of these savings on the combined company’s earnings;
	•	the review by the board with Unocal’s legal and financial advisors of the structure of the merger and the financial and other terms of the merger agreement, including the blend of cash and stock consideration, the covenants of each party and the conditions to consummation of the merger;
	•	the quantitative analyses of the financial terms of the merger presented to the board by Unocal’s financial advisor;

Table of Contents

	•	the opinion of Unocal’s financial advisor that, as of the date of that opinion, and based upon and subject to the qualifications, assumptions and limitations in the opinion, the consideration to be received by holders of Unocal’s common stock in the merger agreement was fair from a financial point of view to those stockholders (see “— Opinion of Unocal’s Financial Advisor”);
	•	the expectation that the merger would qualify as a reorganization for federal income tax purposes.

	•	the risks of the type and nature described under “Risk Factors”;
	•	the challenges of integrating the businesses and operations of the two companies, and the risk that the anticipated cost savings and other expected synergies may not be achieved as and when planned;
	•	with respect to the equity component of the consideration, the volatility of trading prices of oil and gas companies, which typically corresponds to changes in commodity prices, and the fact that the fixed exchange ratio, by its nature, would not adjust upwards to compensate for declines, or downwards to compensate for increases, in Chevron’s stock price prior to completion of the merger; and that the terms of the merger agreement did not include “collar” provisions or stock-price-based termination rights that would be triggered by a decrease in the value of the equity component of the merger consideration attributable to the Chevron stock price;
	•	the interests of certain of Unocal’s officers and directors described under “Interests of Unocal Directors and Executive Officers in the Merger”;
	•	the restrictions on the conduct of Unocal’s business prior to the consummation of the merger, requiring Unocal to conduct its business in the ordinary course consistent with past practice and in a manner not involving the entry by Unocal into businesses that are materially different from the businesses of Unocal on the date of the merger agreement, subject to specific limitations, which may delay or prevent Unocal from undertaking business opportunities that may arise pending completion of the merger;
	•	the requirement that Unocal submit the merger agreement to its stockholders even if the Unocal board withdraws its recommendation, which could delay or prevent Unocal from pursuing a superior proposal if one were to become available; and
	•	the risk, which is common in transactions of this type, that the terms of the merger agreement, including provisions relating to Unocal’s payment of a termination fee under specified circumstances, might discourage other parties that could otherwise have an interest in a business combination with, or an acquisition of, Unocal from proposing such a transaction (see “The Merger Agreement — Termination of the Merger Agreement”).

	•	You must deliver to Unocal a written demand for appraisal of your shares of Unocal common stock before the vote on the merger agreement at Unocal’s special meeting. This demand will be sufficient if it reasonably informs Unocal of your identity and that you intend by that writing to demand the appraisal of your shares. Voting against, abstaining from voting on or failing to vote on the proposal to adopt the merger agreement will not constitute a written demand for appraisal within the meaning of Section 262. The written demand for appraisal must be in addition to and separate from any proxy you deliver or vote you cast in person.
	•	You must not vote your shares of Unocal common stock in favor of the merger agreement. A proxy that does not contain voting instructions will, unless revoked, be voted in favor of the adoption of the merger agreement. Therefore, if you vote by proxy and wish to exercise appraisal rights, you must vote against the adoption of the merger agreement or mark your proxy card to indicate that you abstain from voting on the adoption of the merger agreement.
	•	You must continuously hold your shares of Unocal common stock from the date of making the demand through the completion of the merger. If you are the record holder of shares of Unocal common stock on the date the written demand for appraisal is made but you thereafter transfer those shares prior to the completion of the merger, you will lose any right to appraisal in respect of those shares.

	Sum-of-the-Parts Analysis

	•	Discounted Cash Flow Method. Morgan Stanley analyzed each individual Unocal business using a discounted cash flow analysis. This discounted after-tax unlevered free cash flow analysis, calculated as of December 31, 2004, was based on company projections. Additionally, Morgan Stanley performed sensitivities, including production profiles and oil prices, on the projections provided by Unocal management. The range of discount rates utilized in this analysis was 8% to 12%, which was chosen based upon an analysis of the weighted average cost of capital of Unocal and other comparable companies.
	•	Multiple Method. For selected business units, Morgan Stanley also reviewed and compared various actual and forecasted financial and operating information of these businesses with that of various precedent transactions which shared certain characteristics with these businesses. Based upon the aggregate transaction value divided by proved reserves in these precedent transactions and Morgan Stanley’s experience in mergers and acquisitions in the energy industry, Morgan Stanley estimated reference valuation metric ranges for these business units. Morgan Stanley then calculated the potential implied after-tax valuation range for these business units.

	Explanation of the Proration of the Stock and Cash Elections

	Proration If Too Much Cash Is Elected

	•	Step 1: Derive the available cash election amount: The available cash election amount is the aggregate cash amount minus the amount of cash to be paid in respect of shares of Unocal common stock as to which a valid election for the mixed merger consideration was made or is deemed to have been made.
	•	Step 2: Derive the elected cash amount: The elected cash amount is an amount equal to $65.00 multiplied by the number of shares of Unocal common stock as to which a valid all-cash election was made.
	•	Step 3: Derive the cash proration factor: The cash proration factor equals the available cash election amount divided by the elected cash amount.
	•	Step 4: Derive the prorated cash merger consideration: The prorated cash merger consideration is an amount in cash equal to $65.00 multiplied by the cash proration factor.
	•	Step 5: Derive the prorated stock merger consideration: The prorated stock merger consideration is a number of shares of Chevron common stock equal to (x) 1.03 multiplied by (y) a number equal to 1 minus the cash proration factor.
	•	Step 6: Determine the stock and cash mix: Each share of Unocal common stock as to which a valid all-cash election was made will be converted into the right to receive the prorated cash merger consideration and the prorated stock merger consideration.

	Proration If Too Many Shares of Chevron Common Stock Are Elected

	•	Step 1: Derive the available cash election amount: As stated above, the available cash election amount is the aggregate cash amount minus the amount of cash to be paid in respect of shares of Unocal common stock as to which a valid election for mixed merger consideration was made or is deemed to have been made.
	•	Step 2: Derive the elected cash amount: As stated above, the elected cash amount is an amount equal to $65.00 multiplied by the number of shares of Unocal common stock as to which a valid all-cash election was made.
	•	Step 3: Derive the excess cash amount: The excess cash amount is the difference between the available cash amount and the elected cash amount.
	•	Step 4: Derive the prorated cash merger consideration: The prorated cash merger consideration is an amount in cash equal to the excess cash amount divided by the number of shares of Unocal common stock as to which a valid all-stock election was made.
	•	Step 5: Derive the stock proration factor: The stock proration factor is a fraction the numerator of which is equal to $65.00 minus the per share prorated cash consideration calculated in Step 4 and the denominator of which is $65.00.
	•	Step 6: Derive the prorated stock merger consideration: The prorated stock merger consideration is a number of shares of Chevron common stock equal to 1.03 multiplied by the stock proration factor.
	•	Step 7: Determine the stock and cash mix: Each share of Unocal common stock as to which a valid all-stock election was made will be converted into the right to receive the prorated cash merger consideration and the prorated stock merger consideration.

	•	by either Chevron or Unocal if:

	–	the merger has not been completed by December 31, 2005 (or if the reason for not closing by December 31, 2005 is that the regulatory conditions specified in the merger agreement have not been satisfied by that date, August 31, 2006) (but neither Chevron nor Unocal can terminate the merger agreement for this reason if its failure to fulfill in any material respect its obligations under the merger agreement has resulted in the failure to complete the merger);
	–	the approval of Unocal stockholders has not been obtained by reason of the failure to obtain the required vote at the Unocal special meeting of stockholders or at any adjournment of that special meeting; or
	–	there is a permanent legal prohibition to closing the merger.

	•	by Chevron if the Unocal board fails to recommend the merger or withdraws or modifies in a manner adverse to Chevron its approval or recommendation of the merger, Unocal breaches its obligation to call the Unocal stockholder meeting or Unocal has materially breached its obligations described above under “No Solicitation” to the material detriment of Chevron.
	•	by Chevron or Unocal if the other party has breached any of its representations, warranties, covenants or obligations under the merger agreement, and that breach would result in the failure to satisfy certain specified closing conditions and is incapable of being cured, or, if capable of being cured, has not been cured within 30 days after the party alleged to have breached receives written notice of the breach.

	•	Chevron terminates the merger agreement because the Unocal board fails to recommend the merger to its stockholders, because the Unocal board otherwise changes or proposes publicly to change its recommendation of the merger to stockholders, because Unocal fails to comply with its obligation to hold the special meeting or to obtain SEC clearance for this proxy statement/ prospectus or because Unocal has materially (and to the material detriment of Chevron) breached its obligations under the merger agreement with respect to non-solicitation of other acquisition proposals as described above;
	•	either Chevron or Unocal terminates the merger agreement because Unocal’s stockholders fail to approve the merger and, prior to the Unocal stockholders’ meeting but after April 4, 2005, an alternative acquisition proposal was made known to Unocal (including any of its agents or representatives) and communicated publicly or to any substantial number of Unocal stockholders or was made directly to Unocal’s stockholders or any person publicly announced an intention (whether or not conditional) to make an alternative acquisition proposal; or

Voting Rights		Each share of Unocal’s common stock entitles its holder to one vote on all matters on which stockholders are entitled to vote.		Each share of Chevron’s common stock entitles its holder to one vote on all matters on which stockholders are entitled to vote.
Conversion Rights		Unocal common stock is not subject to any conversion rights.		Chevron common stock is not subject to any conversion rights.
Stockholder Proposals		Unocal’s bylaws provide that any stockholder who intends to bring a matter before the stockholders’ meeting must deliver written notice of his or her intent to do so to Unocal’s secretary. For an annual meeting, the secretary must receive the notice no later than 90 days prior to the meeting, unless there has been an amendment to the bylaws since the last annual meeting changing the date of the annual meeting, in which case the notice must be delivered no later than 90 days prior to the meeting or the tenth day following the date of public disclosure of the new meeting date. See the subsection entitled “Nomination of Directors” below for more information.		Chevron’s bylaws do not contain advance notice provisions for stockholder proposals. Chevron’s restated certificate of incorporation, however, precludes taking action on any proposal at a stockholder meeting that is not included in the proxy statement for that meeting (unless this requirement is waived by the board of directors). In practice, this means that stockholder proposals must comply with the submission standards under federal proxy rules and must be submitted to Chevron consistent with the company’s deadline set forth in the proxy statement for the prior year’s annual meeting of stockholders.

Nomination of Directors		Unocal’s bylaws provide that a Unocal stockholder may nominate one or more persons for election as directors at an annual or special meeting called for the election of directors, but only if the stockholder delivers written notice of his or her intent to make the nomination to Unocal’s secretary. The timing requirements for receiving the notice are similar to those for receiving notice of stockholder proposals described above. The notice must include: • such information concerning each nominee as would be required under SEC rules to be included in a proxy statement soliciting proxies for the election of the nominee as a director; and • a written and signed consent of each nominee to serve as a Unocal director if elected. In addition, if the number of directors to be elected to the board of directors is increased and there is no public announcement naming all of the		Chevron’s board of directors proposes a slate of nominees for director each year.

Classification of Board of Directors		Unocal’s restated certificate of incorporation and bylaws provide that Unocal’s board of directors is to be divided into three classes, with the classes having an equal or near equal number of directors and the directors of each class entitled to serve for three-year terms. Unocal’s board of directors currently has three outstanding classes, two composed of three members and one composed of four members.		Chevron does not have a classified board. Chevron’s bylaws require that all directors be elected at each annual meeting of stockholders for a term of one year.
Removal of Directors		Neither Unocal’s bylaws nor its restated certificate of incorporation contains any express provisions with respect to the removal of directors; however, Delaware law provides that directors of a corporation with a classified board may only be removed for cause.		Chevron stockholders may remove directors with or without cause by the affirmative vote of the majority of stockholders entitled to vote in the election of directors.

		Unocal Stockholder Rights		Chevron Stockholder Rights
Amendment of Certificate of Incorporation		The affirmative vote of at least 75% of the voting power of Unocal’s outstanding voting stock is required to amend various provisions of the Unocal restated certificate of incorporation, including provisions relating to • the adoption, amendment or repeal of bylaws, • the classified board, • business combinations, • actions by stockholders by written consent without a meeting, • the call of special meetings, and • amendments to the restated certificate of incorporation.

Amendment of Bylaws		Unocal’s bylaws may be amended by a vote of 75% of the outstanding stock entitled to vote or by the board of directors. However, any bylaw amendment by the board of directors regarding an increase or decrease to the number of directors or regarding the amendment of bylaws requires a resolution adopted by at least 75% of the directors.		Chevron’s bylaws may be amended by the affirmative vote of the holders of a majority of the outstanding shares of common stock, or by a resolution of the board approved by at least a majority of the directors then in office. However, special restrictions apply to the amendment of the bylaw provisions governing change in control benefit protection.
Stockholder Rights Plan		Unocal’s stockholder rights plan grants stockholders one preferred stock purchase right for each share of common stock held. Ten business days after a public announcement that a person has acquired beneficial ownership of 15% or more of Unocal’s common stock or the commencement of a tender offer that, if successful, would result in such an acquisition, each purchase right will become exercisable and entitle its holder to purchase from Unocal that number of shares of Unocal’s common stock having a market value equal to twice the $180 exercise price of the right. However, Unocal’s stockholder rights plan has been amended so that it will not apply to the merger.		Chevron does not currently have a stockholder rights plan.

		Unocal Stockholder Rights		Chevron Stockholder Rights
Certain Business Combinations		Unocal’s restated certificate of incorporation requires the affirmative vote of not less than 75% of the outstanding shares of Unocal’s voting stock to approve any of the following: • mergers or consolidations with a “related corporation” (as described below); • a sale or exchange of all or a substantial part of Unocal’s assets to or with a related corporation; or • the issuance or delivery of Unocal stock or other Unocal securities in exchange for any properties or assets of or securities issued by a related corporation, or in a merger of any affiliate of Unocal with or into a related corporation or its affiliates. For this purpose, a “related corporation” means any corporation that owns, together with its affiliates, more than 10% of the voting power of Unocal’s outstanding voting stock. The above 75% stockholder voting requirement does not apply: • if the transaction was approved by 75% of the directors prior to the related corporation’s acquisition of more than 10% of the total voting power of Unocal’s outstanding voting stock; or • to any transaction between Unocal and any corporation of which Unocal owns more than 50% or more of the voting stock.		Chevron’s restated certificate of incorporation provides that a fairness committee of the board of directors will be established during any period of the existence of a 10% stockholder. The fairness committee will consist of all directors serving at the time any such stockholder becomes a 10% stockholder. The fairness committee will look into the fairness to the corporation and its stockholders of transactions the committee deems “extraordinary,” which may include mergers or liquidations, transactions with major stockholders, major asset sales or recapitalizations. The fairness committee may require that the corporation’s stockholders ratify such an extraordinary transaction by the affirmative vote of two- thirds of the shares of outstanding common stock or a majority of the outstanding shares of common stock, excluding shares held by the 10% stockholder.

	(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of sec. 251 of this title.
	(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

	a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;
	b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders;
	c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or
	d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

	(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under sec. 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

	(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or
	(2) If the merger or consolidation was approved pursuant to sec. 228 or sec. 253 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall

	be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.
