Dear Stockholder:

You are cordially invited to attend a special meeting of stockholders of Giant Industries, Inc., which will be held at located at , on , 2006, at , local time.

At the meeting, you will be asked to consider and vote on a proposal to adopt a merger agreement that Giant has entered into with Western Refining, Inc. and a wholly-owned subsidiary of Western and approve the merger. If our stockholders adopt the merger agreement and approve the merger and the merger is subsequently completed, Giant will become a wholly-owned subsidiary of Western, and you will be entitled to receive $83.00 in cash for each share of Giant common stock that you own. A copy of the merger agreement is attached as Annex A to the accompanying proxy statement, and you are encouraged to read it in its entirety.

After careful consideration, our board of directors has unanimously approved the adoption of the merger agreement and the approval of the merger and determined that the merger and the merger agreement are advisable and in the best interests of Giant and its stockholders. Our board of directors recommends that you vote “FOR” the adoption of the merger agreement and the approval of the merger. In reaching its determination, our board of directors considered a number of factors, including the opinion of our financial advisor, which is attached as Annex B to the accompanying proxy statement, and which you are urged to read in its entirety.

Our board of directors also unanimously recommends that our stockholders vote “FOR” approval of adjournment or postponement of the special meeting, if necessary, to solicit additional proxies in favor of the proposal to adopt the merger agreement.

If my shares are held in “street name” by my broker, will my broker vote my shares for me?

Your broker will only be permitted to vote your shares if you instruct your broker how to vote. You should follow the procedures provided by your broker regarding the voting of your shares.

What if I do not vote?

If you fail to vote by proxy, either by mail, through the Internet or by telephone, or in person, it will have the same effect as a vote “AGAINST” adoption of the merger agreement.

When should I send in my proxy card?

You should send in your proxy card as soon as possible so that your shares will be voted at the special meeting.

May I change my vote after I have mailed my signed proxy card?

Yes. You may change your vote at any time before your proxy card is voted at the special meeting. You can do this in one of following ways.

iii

and submit a new proxy card either by mail, through the Internet or by telephone. Third, you can attend the meeting and vote in person. Your attendance alone will not revoke your proxy. If you have instructed a broker to vote your shares, you must follow directions received from your broker to change those instructions.

May I vote in person?

Yes. You may attend the special meeting of stockholders and vote your shares of common stock in person. If you hold shares in “street name” you must provide a legal proxy executed by your bank or broker in order to vote your shares at the meeting.

The Merger

What is the proposed transaction?

Western will acquire us by merger. A newly-formed subsidiary of Western will merge into Giant with Giant as the surviving corporation. We will cease to be a publicly-traded company and will instead become a wholly-owned subsidiary of Western.

If the merger is completed, what will I be entitled to receive for my shares of Giant common stock and when will I receive it?

You will be entitled to receive $83.00 in cash, without interest and less any applicable withholding taxes, for each share of our common stock that you own.

After the merger closes, Western will arrange promptly for a letter of transmittal or other instructions to be sent to each stockholder. In the case of shares that are certificated, the merger consideration will be paid to each stockholder once that stockholder submits the letter of transmittal, properly endorsed stock certificates and any other required documentation. In the case of uncertificated shares, the merger consideration will be paid to each stockholder once the appropriate book entries are made.

Am I entitled to appraisal rights?

Yes. Under the General Corporation Law of the State of Delaware, holders of Giant common stock who do not vote in favor of adopting the merger agreement will have the right to seek appraisal of the fair value of their shares as determined by the Delaware Court of Chancery if the merger is completed, but only if they submit a written demand for an appraisal prior to the vote on the adoption of the merger agreement and they comply with the Delaware law procedures explained in this proxy statement. For additional information about appraisal rights, see “Appraisal Rights” beginning on page .

Why is the Giant board recommending the merger?

Our board believes that the merger and the merger agreement are advisable and in the best interests of Giant and its stockholders and unanimously recommends that you adopt the merger agreement. To review our board’s reasons for recommending the merger, see the section entitled “Reasons for the Merger and Recommendation of the Board of Directors” on pages through of this proxy statement.

Will the merger be a taxable transaction to me?

Yes. The receipt of cash for shares of Giant common stock pursuant to the merger will be a taxable transaction for U.S. federal income tax purposes. In general, you will recognize gain or loss equal to the difference between the amount of cash you receive and the adjusted tax basis of your shares of our common stock. See the section entitled “Material U.S. Federal Income Tax Consequences” on pages through of this proxy statement for a more detailed explanation of the tax consequences of the merger. You also should consult your tax advisor on how specific tax consequences, including any state tax consequences, of the merger apply to you.

When is the merger expected to be completed?

We are working toward completing the merger as promptly as possible. We currently expect to complete the merger as promptly as possible after the special meeting and after all the conditions to the merger are satisfied or waived, including stockholder adoption of the merger agreement and approval of the merger at the special meeting and the expiration or termination of the waiting period under U.S. antitrust laws and applicable state or foreign antitrust laws. We, along with Western, filed pre-merger notifications with the U.S. antitrust authorities pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976 on September 7, 2006.

Should I send in my Giant stock certificates now?

No. After the merger is completed, Western will arrange to have written instructions for exchanging your Giant stock certificates sent to you. If your shares are certificated, you must return your Giant stock certificates as described in the instructions. If your shares are certificated, you will receive your cash payment as soon as practicable after Western receives your Giant stock certificates and any completed documents required in the instructions. If your shares are held in book-entry or other uncertificated form, you will receive your cash payment as soon as practicable after the appropriate book entries are made.

Holders of our common stock are urged to, and should, read the Deutsche Bank opinion carefully and in its entirety. The Deutsche Bank opinion was addressed solely to our board of directors, was limited to the fairness, from a financial point of view, of the merger consideration to holders of our common stock as of the date of the opinion, and Deutsche Bank expressed no opinion as to the merits of the underlying decision by Giant to engage in the merger or as to how any holder of shares of Giant stock should vote with respect to the merger. The summary of the Deutsche Bank opinion set forth in this proxy statement is qualified in its entirety by reference to the full text of such opinion.

Deposit (page )

Concurrently with the execution of the merger agreement, Western deposited $12.5 million into an escrow account. This amount will be increased by Western to $25 million if the closing has not occurred by November 30, 2006 because the waiting period applicable to the consummation of the merger has not expired or been terminated under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (which we refer to in this proxy statement as the HSR Act) or any waiting period or any required consent under any applicable state or foreign competition or antitrust law has not expired or been obtained. The deposit is payable to us as liquidated damages if we terminate the merger agreement due to Western’s breach or if the merger has not been consummated by March 31, 2007 because the waiting period applicable to the consummation of the merger has not expired or been terminated under the HSR Act or any waiting period or any required consent under any applicable state or foreign competition or antitrust law has not expired or been obtained. At the effective time of the merger, the deposit will be paid to the paying agent for distribution to our stockholders as part of the merger consideration.

Conditions to the Merger (page )

We and Western will not complete the merger unless a number of conditions are satisfied or waived. These conditions include:


	•	the adoption of the merger agreement and the approval of the merger by our stockholders;

	•	(1) the applicable waiting period under the HSR Act must have expired or been terminated and (2) any mandatory waiting period or required consent under any applicable state or foreign competition or antitrust law or regulation must have expired or been obtained, except in the case of clause (2) of this bullet point where the failure to observe such waiting period or obtain such consent would not reasonably be expected to delay or prevent the consummation of the merger or have a material adverse effect on the expected benefits of the transactions contemplated by the merger agreement to Western;

	•	neither we nor Western shall be subject to any court decree, order or injunction which prohibits the consummation of the merger, and no statute, rule or regulation shall have been enacted by any governmental authority which prohibits or makes unlawful the consummation of the merger;

	•	the accuracy of the parties’ representations and warranties set forth in the merger agreement;


	•	the performance by each party of its covenants and agreements under the merger agreement;

	•	the consulting and non-competition agreement entered into as of August 26, 2006 between Fred L. Holliger and Western, which is to be effective as of the effective time of the merger, must remain in full force and effect;

	•	the number of dissenting shares for which appraisal rights are exercised do not exceed 10% of the total number of shares of our common stock outstanding; and

	•	if Western has requested that we commence a debt tender offer and consent solicitation with respect to our outstanding 11% Senior Subordinated Notes due 2012 and/or our outstanding 8% Senior Subordinated Notes due 2014, then not less than a majority of the aggregate principal amount of the applicable Senior Subordinated Notes shall have been tendered and accepted for payment by us in accordance with the terms of the debt tender offer, and the indenture amendments applicable with respect to the applicable Senior Subordinated Notes shall become effective, in each case concurrently with the effectiveness of the merger.

Termination of the Merger Agreement (page )

The merger agreement may be terminated and the merger may be abandoned at any time prior to the effective time of the merger (notwithstanding any approval by our stockholders):


	•	by the mutual written consent of us and Western;

	•	by either us or Western, if:


	•	the merger has not been consummated by March 31, 2007, provided that this right to terminate is not available to any party whose failure to fulfill in any material respect any obligation under the merger agreement has been a principal cause of or resulted in the failure of the merger to occur by March 31, 2007; or

	•	any governmental order, decree, ruling or action permanently restraining, enjoining or otherwise prohibiting the merger has become final and non-appealable;


	•	by Western, if:


	•	our board withdraws, modifies, withholds or changes its recommendation, in a manner adverse to Western, that our stockholders adopt the merger agreement, or recommends a superior proposal; or

	•	we breach or fail to perform any representation, warranty, covenant or agreement that would result in the failure of a condition to Western’s obligation to effect the merger being satisfied and which is not cured within 30 days after written notice of the breach or failure to perform is given to us;


	•	by us, if:


	•	prior to our stockholders adopting the merger agreement and approving the merger, our board withdraws its approval or recommendation of the merger with Western and recommends or declares advisable to our stockholders a superior proposal, provided that (1) we inform Western of our intent to effect such termination at least four business days prior to such termination, (2) we disclose the terms and conditions of the superior proposal and the identity of the third party, and provide copies of the documentation regarding the superior proposal, (3) we provide Western a reasonable opportunity during the four-business day period to adjust the terms and conditions of the merger agreement and to negotiate adjusted terms and conditions such that our board determines (in good faith, after consultation with nationally recognized outside legal counsel) that the third-party proposal is no longer considered a superior proposal, and (4) we pay Western a termination fee and reimburse Western for its expenses; or

	•	Western breaches or fails to perform any representation, warranty, covenant or agreement that would result in the failure of a condition to our obligation to effect the merger being satisfied and which is not cured within 30 days after written notice of the breach or failure to perform is given to Western.

Termination Fee (page )

The merger agreement obligates us to pay a termination fee to Western of $37.5 million, plus reimburse up to $1 million of Western’s expenses relating to the merger, if:


	•	we terminate the merger agreement prior to the special meeting because our board has withdrawn its approval or recommendation of the merger with Western and recommends or declares advisable to our stockholders a superior proposal, and Western elects not to adjust the terms and conditions of the merger agreement in a manner that would permit our board to conclude (in good faith, after consultation with nationally recognized outside legal counsel) that the third-party proposal is no longer a superior proposal; or

	•	the merger agreement is terminated by Western because our board withdraws, modifies, withholds or changes, in a manner adverse to Western, its recommendation or approval of the merger agreement or the merger, or recommends a superior proposal.

In the event that we terminate the merger agreement due to a Western breach, or if the merger has not been consummated by March 31, 2007 because the waiting period applicable to the consummation of the merger has not expired or been terminated under the HSR Act or any waiting period or any required consent under any applicable state or foreign competition or antitrust law has not expired or been obtained, then we are entitled to retain the $25 million deposit as liquidated damages as our sole remedy. See “The Merger Agreement — Deposit.”

If the merger agreement is terminated for any reason other than a termination by Western following our breach of the merger agreement, and as of the date of termination we have undertaken any debt tender offer at the request of Western, then Western shall reimburse us for our reasonable costs and expenses incurred in connection with the debt tender offer, up to $250,000. See “The Merger Agreement — Debt Tender Offer.”

Regulatory Matters (page )

Under the provisions of the HSR Act, we and Western may not complete the merger until we have made certain filings with the Federal Trade Commission and the United States Department of Justice and the applicable waiting period has expired or been terminated. We and Western filed pre-merger notifications with the U.S. antitrust authorities pursuant to the HSR Act on September 7, 2006. In addition, the merger may be subject to state or foreign competition or antitrust laws. We cannot assure you that a challenge to the merger on antitrust grounds will not be made or, if a challenge is made, of the result.

Appraisal Rights (page )

Under Delaware law, if you do not vote for adoption of the merger agreement and prior to the special meeting you make a written demand and you strictly comply with the other statutory requirements of the General Corporation Law of the State of Delaware, you may elect to receive, in cash, the judicially determined fair value of your shares of stock in lieu of the $83.00 per share merger consideration. This value could be more or less than or the same as the cash merger consideration.

Giant Stock Options (page )

Giant stock options that are outstanding as of the effective time of the merger will be cancelled. At the effective time of the merger, the holders of those options will become entitled to receive a cash payment equal to the number of shares subject to their stock options multiplied by the difference between $83.00 and the per share option exercise price, less applicable withholding taxes.

Interests of Certain Persons in the Merger (page )

As you consider the recommendation of our board of directors, you should be aware that some of our executive officers and directors have relationships with Giant and/or Western that are different from, or in addition to, those of other stockholders and that may present actual or potential conflicts of interest. These interests are discussed in detail in the section entitled “The Merger — Interests of Certain Persons in the Merger.”

No Solicitation (page )

We have agreed that neither we nor any of our officers, directors, employees, agents or representatives, including our investment bankers, attorneys and accountants, will solicit, initiate or encourage any acquisition proposal by a third party.

Until such time as our stockholders adopt the merger agreement and approve the merger, we may provide information to and participate in discussions or negotiations with a third party if we receive an unsolicited bona fide acquisition proposal. Our board may take these actions only if:


	•	the third party has entered into a customary confidentiality agreement, which would not prevent us from complying with our non-solicitation obligations with respect to Western;

	•	our board determines in good faith, after consultation with outside counsel and our financial advisors, that it is reasonably likely that the acquisition proposal will result in a superior proposal; and

	•	our board determines in good faith after consultation with outside counsel that the failure to so act would be inconsistent with its fiduciary obligations under applicable law.

We have agreed to promptly notify Western of our receipt of any acquisition proposal, request for information or inquiry with respect to any acquisition proposal, the material terms of any such acquisition proposal or inquiry, and the identity of the person making any such acquisition proposal or inquiry. We are also required to keep Western informed of any material changes, additions or adjustments to the terms of any such acquisition proposal or inquiry. We must also give Western notice if our board determines to participate in any such discussions or negotiations or provide any information to the third party.

THE SPECIAL MEETING OF GIANT STOCKHOLDERS

By unanimous vote, our board has determined that the merger agreement and the merger are advisable and in the best interests of Giant and its stockholders, and has approved the merger agreement and the merger. Our board unanimously recommends that our stockholders vote “FOR” adoption of the merger agreement and approval of the merger.

Record Date; Stock Entitled to Vote; Quorum

The holders of record of shares of our common stock as of the close of business on , 2006, which is the record date for the special meeting, are entitled to receive notice of and to vote at the special meeting.

On the record date, there were approximately shares of our common stock outstanding held by approximately stockholders of record. Holders of a majority of the shares of our common stock issued and outstanding as of the record date and entitled to vote at the special meeting must be present in person or

represented by proxy at the special meeting to constitute a quorum to transact business at the special meeting. Shares of our common stock represented at the special meeting but not voting, including shares of our common stock for which proxies have been received but for which stockholders have abstained, as well as shares held by brokers or other nominees in “street name” for customers who are beneficial owners that are not voted at the meeting, will be counted as present for purposes of determining the existence of a quorum. In the event that a quorum is not present at the special meeting, we currently expect that we will adjourn or postpone the meeting to solicit additional proxies.

Vote Required

Adoption of the merger agreement and approval of the merger requires the affirmative vote of the holders of a majority of the shares of our common stock outstanding on the record date and entitled to vote.

Each holder of a share of our common stock is entitled to one vote per share. Failure to vote your proxy (either through the Internet, by telephone or by returning a properly executed proxy card) or to vote in person will have the same effect as a vote “AGAINST” adoption of the merger agreement and approval of the merger.

Brokers or other nominees who hold shares of our common stock in “street name” for customers who are the beneficial owners of such shares may not give a proxy to vote those customers’ shares in the absence of specific instructions from those customers. These non-voted shares of our common stock will not be counted as votes cast or shares voting and will have the same effect as votes “AGAINST” adoption of the merger agreement and approval of the merger.

The proposal to approve adjournment or postponement of the special meeting if deemed necessary to facilitate the adoption of the merger agreement and the approval of the merger, including to permit the solicitation of additional proxies if there are not sufficient votes at the time of the special meeting to adopt the merger agreement and approve the merger, requires the affirmative vote of a majority of the shares of our common stock represented in person or by proxy at the special meeting, even if less than a quorum.

Voting

Stockholders may vote their shares of our common stock by attending the special meeting and voting their shares in person, or by completing the enclosed proxy card, signing and dating it and mailing it in the enclosed postage-prepaid envelope. All shares of our common stock represented by properly executed proxies received in time for the special meeting will be voted at the special meeting in the manner specified by the holder. If a written proxy card is signed by a stockholder and returned without instructions, the shares of our common stock represented by the proxy will be voted “FOR” adoption of the merger agreement and approval of the merger and “FOR” approval of adjournment or postponement of the special meeting if deemed necessary to facilitate the adoption of the merger agreement and approval of the merger, including to permit the solicitation of additional proxies if there are not sufficient votes at the time of the special meeting to approve the merger proposal.

In addition, stockholders may submit a proxy through the Internet or by telephone by following the instructions included with the enclosed proxy card. If you submit a proxy through the Internet or by telephone, please do not return the proxy card. You should be aware that in submitting a proxy through the Internet, you may incur costs such as telephone and Internet access charges for which you will be responsible. The Internet voting facility and the telephone voting facility for stockholders of record will close at , Time, on , 2006.

Stockholders who hold their shares of Giant common stock in “street name,” meaning in the name of a bank, broker or other person who is the record holder, must either direct the record holder of their shares of our common stock how to vote their shares or obtain a proxy from the record holder to vote their shares at the special meeting.

Revocability of Proxies

You can revoke your proxy at any time before it is voted at the special meeting by:


	•	submitting another properly completed proxy bearing a later date;

	•	giving written notice of revocation to any of the persons named as proxies or to the Corporate Secretary of Giant;

	•	voting in person at the special meeting.

If your shares of our common stock are held in the name of a bank, broker, trustee or other holder of record, you must follow the instructions of your broker or other holder of record to revoke a previously given proxy. If your broker or nominee allows you to submit a proxy by telephone or through the Internet, you may be able to change your vote by submitting a proxy again by telephone or through the Internet.

Solicitation of Proxies

In addition to solicitation by mail, our directors, officers and employees may solicit proxies by telephone, other electronic means or in person. These people will not receive any additional compensation for their services, but we will reimburse them for their out-of-pocket expenses. We will reimburse banks, brokers, nominees, custodians and fiduciaries for their reasonable expenses in forwarding copies of this proxy statement to the beneficial owners of shares of our common stock and in obtaining voting instructions from those owners. We will bear all expenses of filing, printing and mailing this proxy statement.

We have retained Georgeson Shareholder Communications to assist in the solicitation of proxies by mail, telephone or other electronic means, or in person, for a fee of approximately $ plus expenses relating to the solicitation.

Other Business

We are not currently aware of any business to be acted upon at the special meeting other than the matters discussed in this proxy statement. Under our bylaws, business transacted at the special meeting is limited to matters relating to the purposes stated in the notice of special meeting, which is provided at the beginning of this proxy statement. If other matters do properly come before the special meeting, or at any adjournment or postponement of the special meeting, we intend that shares of our common stock represented by properly submitted proxies will be voted by and at the discretion of the persons named as proxies on the proxy card. In addition, the grant of a proxy will confer discretionary authority on the persons named as proxies on the proxy card to vote in accordance with their best judgment on procedural matters incident to the conduct of the special meeting, such as a motion to adjourn in the absence of a quorum or a motion to adjourn for other reasons, if necessary, including to solicit additional votes in favor of adoption of the merger agreement.

THE MERGER

This discussion of the merger is qualified by reference to the merger agreement, which is attached to this proxy statement as Annex A. We urge you to read the entire merger agreement carefully, as it is the legal document that governs the merger.

Background of the Merger

Our senior management and board of directors periodically review strategic matters relating to our growth.

On or about May 27, 2004, our chief executive officer, Mr. Holliger, met with the chief executive officer of Western, Mr. Foster, at which time Mr. Foster asked whether Giant would be interested in a possible business combination with Western. Mr. Holliger advised Mr. Foster that Giant would not likely be interested in a business combination at that time because Giant’s stock price was trading below anticipated future levels due to expected improvement in financial condition.

Between 2004 and 2006, our board of directors periodically discussed strategic alternatives available to Giant and its individual business units. In furtherance of these discussions, at a meeting of the board held on April 10-11, 2006, our senior management discussed with our board options potentially available to Giant. In connection with this discussion, the board was provided a five-year financial projection and information on the refining industry prepared by third-party sources.

On April 13, 2006, Mr. Foster contacted Mr. Holliger and inquired as to whether Mr. Holliger would be willing to meet to discuss a possible business combination between Western and Giant. Mr. Holliger indicated that he would be willing to meet with Mr. Foster.

On May 25, 2006, Mr. Foster met with Mr. Holliger in Giant’s offices. Mr. Foster expressed interest in a possible purchase of Giant in a cash transaction at a premium over the current trading price of Giant’s stock. Mr. Holliger met separately with the chairman and the chief executive officer of a second independent refining company (which is referred to in this proxy statement as Company X) on May 25, 2006, and they indicated that Company X would be interested in a business combination involving cash and stock at a premium over the current trading price of Giant’s stock.

Our senior management again discussed strategic alternatives potentially available to Giant with the board at a meeting held on June 6, 2006. Prior to the meeting, senior management had prepared and circulated to the board a financial analysis of Giant, including an analysis of the stock performance of Giant compared to other refining companies during 2006, a five-year financial projection and various potential valuations of Giant based on different valuation methodologies. During the meeting, the board discussed refineries that were available for purchase and other assets being offered for sale in which Giant might have an interest. Mr. Holliger advised the board that he had talked to the chief executive officer of a third independent refining company about the possibility of combining the two respective businesses under a variety of structures, but the chief executive officer of the other company indicated that they were not interested in pursuing any of the structures discussed. Mr. Holliger also advised the board that he had been separately approached by the chairman and chief executive officer of Company X and the chief executive officer of Western about a business combination. The board discussed the possibility of pursuing a transaction with each of these companies, and ultimately directed Mr. Holliger to obtain information from both companies regarding their interest in a transaction so that the board could determine whether it might be willing to consider a proposed transaction. The board was particularly interested in the valuations that Company X and Western would ascribe to Giant.

On June 7, 2006, Mr. Holliger spoke with Mr. Foster regarding Western’s interest in acquiring Giant. Mr. Foster indicated that Western’s board might be interested in making an offer for Giant at $75 per share, which represented a premium above the then-current trading price of Giant’s common stock. Mr. Holliger advised Mr. Foster that he believed that the $75 per share price would likely be viewed by Giant’s board as too low.

On June 8, 2006, Mr. Holliger contacted the chairman of Company X in order to clarify the proposed structure of Company X’s offer to acquire Giant for stock and cash.

On June 13, 2006, Mr. Holliger and the chairman of Company X further discussed the pricing of a proposed business combination of the two companies.

On June 13, 2006, Mr. Holliger spoke with Mr. Foster regarding Western’s interest in acquiring Giant. Mr. Foster advised Mr. Holliger that Western remained interested at a price of $75 per share, and Mr. Foster stated that Western might pay as much as $77 per share if Western could get comfortable with Giant’s new crude oil pipeline during due diligence. Mr. Holliger advised Mr. Foster that he would discuss the price with Giant’s board members.

Between June 13 and June 20, 2006, Mr. Holliger contacted members of Giant’s board to discuss the progress of the discussions with Western and Company X. On June 20, 2006, Mr. Holliger informed Mr. Foster that unless Western’s offer exceeded $80 per share, Giant’s board would not likely be interested in continuing discussions regarding a possible transaction. On June 20, 2006, Mr. Holliger also informed the chairman of Company X that he had discussed Company X’s interest in Giant with various board members. Mr. Holliger informed Company X’s chairman that Giant was willing to provide Company X with the additional information that it needed to make an offer but that Giant’s board likely would only be interested if Company’s X’s offer exceeded $80 per share. Company X’s chairman indicated to Mr. Holliger that he would need additional information regarding Giant’s proposed capital expenditures.

On June 21, 2006, Mr. Holliger sent to Company X’s chief executive officer a letter regarding the timing of Giant’s capital expenditures.

On June 22, 2006, Mr. Holliger spoke with Mr. Foster regarding Western’s interest in acquiring Giant. Mr. Foster told Mr. Holliger that Western might be interested in purchasing Giant at approximately $80 per share, but Western must understand the potential benefits from Giant’s new crude oil pipeline.

On June 22, 2006, Mr. Holliger spoke with Company X’s chairman and chief executive officer to discuss pricing for a proposed business combination between the two companies. Mr. Holliger indicated the he would discuss Company X’s interest further with Giant’s board.

In late June 2006, Mark Cox, our chief financial officer, contacted Deutsche Bank Securities Inc. about representing Giant.

On June 26, 2006, Mr. Foster advised Mr. Holliger that Western would be interested in acquiring Giant at $80 per share in a transaction with no contingencies, other than customary environmental, regulatory and corporate conditions to closing.

On June 29, 2006, the chairman of Company X advised Mr. Holliger that he would meet with Company X’s investment bankers, and on June 30, 2006, Company X delivered a preliminary due diligence request to senior management of Giant.

On July 3, 2006, after speaking informally with several Giant board members, Mr. Holliger informed Mr. Foster that Giant’s board was willing to engage an investment bank and provide the due diligence information necessary for Western to make an offer to Giant. Mr. Holliger advised Mr. Foster that if Western remained interested after conducting its due diligence, then it would need to submit a formal proposal to Giant’s board.

On July 3, 2006, Company X and Giant entered into a confidentiality agreement, which covered both past and future disclosures of information related to a possible transaction.

Between July 3 and July 6, 2006, Mr. Foster spoke with Western’s financial advisors regarding the amount of due diligence that would be required in order to submit a written offer to Giant’s board. On July 6, 2006, Western submitted a preliminary due diligence list to Mr. Holliger and Giant’s senior management.

Prior to July 6, 2006, Western advised Giant that they would be engaging Bank of America Securities as financial advisor in connection with the due diligence and a possible transaction. Company X advised Giant that they would be engaging a separate financial advisor for the same purpose.

On July 6, 2006, representatives of Company X and their financial advisors met with our senior management and representatives of Deutsche Bank in a due diligence session at the office of our outside counsel. Following this

meeting, the chief executive officer of Company X reaffirmed to Mr. Holliger Company X’s interest in continuing discussions about a possible cash and stock transaction.

On July 7, 2006, our chief financial officer sent a capital expenditure schedule to Company X and Western.

On July 10, 2006, Western and Giant entered into a confidentiality agreement, which covered both past and future disclosures of information related to a possible transaction.

Company X asked for our permission to permit their financial advisor to engage an engineering consulting firm which had worked with us for the purpose of utilizing a Giant computer model to analyze alternative crude oil inputs and refined products outputs for our Yorktown refinery, and we entered into a confidentiality agreement, dated July 12, 2006, with the financial advisor for Company X.

On July 11, 2006, representatives of Western, its outside counsel and Bank of America Securities met with our chief financial officer and general counsel and representatives of Deutsche Bank in a due diligence session on legal and environmental matters at the office of our outside counsel. On July 18, 2006, Western and its counsel and financial advisors returned for a due diligence session with our senior management related to our business and operational matters. At this meeting, our chief financial officer provided and discussed with Western a financial model, including a capital expenditure schedule and certain financial forecasting information. Following both of these meetings, Mr. Foster reaffirmed to Mr. Holliger Western’s interest in purchasing Giant for cash.

On July 14, 2006, Western’s outside counsel provided to our general counsel and our outside counsel a draft cash merger agreement.

On July 19, 2006, our chief financial officer provided the same financial model previously provided to Western to Deutsche Bank, and representatives of Deutsche Bank forwarded the financial model to Company X’s financial advisor. Thereafter, on July 21, 2006, our chief financial officer and representatives of Deutsche Bank had a conference call with representatives of Company X and its financial advisor to discuss the financial model.

On July 19, 2006, Giant authorized the same engineering consulting firm discussed above to provide Western with information regarding potential opportunities to expand our Yorktown refinery operations.

On July 20, 2006, Mr. Holliger sent a letter to Company X’s chief executive officer regarding strategic due diligence issues that our senior management and board would need to discuss regarding Company X in order to evaluate any Company X offer that included Company X stock as part of the consideration.

On July 21, 2006, our chief financial officer and general counsel had a conference call with senior management of Company X on due diligence matters.

On July 24, 2006, Deutsche Bank and our senior management entered into an agreement regarding Deutsche Bank’s engagement as our financial adviser.

On July 26, 2006, Deutsche Bank, on our behalf, sent letters to the chief executive officers of Western and Company X asking them, if they were interested in doing so, to provide us with a non-binding letter of interest for a business combination with Giant, including price, terms, sources of financing and other material terms. Deutsche Bank asked for a response by July 31, 2006.

On July 28, 2006, our senior management and representatives of Deutsche Bank traveled to the executive offices of Company X to meet with senior management of Company X and its financial advisor in a due diligence session of Company X.

On July 31, 2006, Western submitted a non-binding proposal for the acquisition of 100% of our shares in a merger transaction at a cash price per share of $80.00. Western’s proposal was subject to confirmatory due diligence, the negotiation and execution of a definitive merger agreement, and final approval of its board of directors. The proposal estimated a two-week period to satisfy these conditions, and was accompanied by a firm commitment letter from Bank of America, N.A. and Banc of America Securities LLC for the full amount of financing necessary to consummate the transaction. Mr. Holliger circulated the proposal to the board members.

On August 2, 2006, Company X submitted a non-binding proposal for the acquisition of 100% of our shares in a merger transaction at a price per share equal to $85.00, payable $51.00 in cash and $34.00 in shares of Company X

common stock valued at the average closing price during the 20 trading days prior to the execution of the merger agreement. Company X’s acquisition proposal was subject to confirmatory due diligence, which it estimated would take three to four weeks. During the due diligence period, Company X indicated that the merger agreement and the financing plan for the transaction would be completed. Mr. Holliger circulated the proposal to the board members.

Prior to August 4, 2006, Deutsche Bank sent to the board a package of discussion materials prepared by them, including an industry overview, a summary of the indications of interest received from Western and Company X, information regarding our valuation, information regarding a possible transaction with Western and information regarding a possible transaction with Company X.

On August 4, 2006, our board met in a special meeting to consider, among other matters, the proposals submitted by Western and Company X. The board ratified the Deutsche Bank engagement agreement, and representatives of Deutsche Bank joined the meeting. The representatives of Deutsche Bank reviewed the discussion materials with the board and addressed numerous questions from the board. The board discussed the proposals, including whether any proposal should be entertained. Mr. Holliger advised the board that Western would like him to sign a consulting agreement as part of any transaction, and described the proposed terms thereof. The board authorized Mr. Holliger to approach Western with a price of $85.00 per share.

Between August 7 and August 10, 2006, Mr. Holliger and Mr. Foster discussed the terms of the Western acquisition proposal, including pricing. On August 7, 2006, Giant announced its earnings results for the second quarter of 2006. On August 8, 2006, Mr. Foster advised Mr. Holliger that Western would pay $81.00 per share, and Western announced its earnings results for the second quarter of 2006.

On August 9, 2006, the chief executive officer of Company X discussed possible ideas to secure regulatory approval of a combination of Giant with Company X with Mr. Holliger.

On August 10, 2006, Mr. Foster advised Mr. Holliger that Western would pay $83.00 per share. Mr. Holliger advised Mr. Foster that he would discuss the offer with Giant’s board.

Between August 11 and August 14, 2006, Mr. Holliger discussed the status of price negotiations and the terms of the Western acquisition proposal with members of our board of directors.

Between August 14, 2006 and August 22, 2006, certain of our officers and certain officers from Western, along with counsel, began negotiating the terms of the merger agreement, and Western continued its due diligence. Mr. Holliger engaged separate counsel, and during this time period negotiated with Mr. Foster and Western’s counsel the terms of his consulting agreement.

On August 15, 2006, Mr. Holliger and Company X’s chief executive officer discussed the valuation of Company X stock as well as Company X’s plans for Giant’s Yorktown refinery.

On August 21, 2006, Mr. Holliger received additional materials regarding the trading value of Company X’s stock from Company X’s chief executive officer.

On August 22, 2006, our board of directors began a regularly scheduled two-day meeting. On the first day, in addition to regular agenda matters, Messrs. Holliger, Gust, Cox and Bullerdick advised the board about the status of negotiations concerning the merger with Western. The next day, the board reconvened to further discuss Western’s acquisition proposal. Representatives from Deutsche Bank attended the meeting in person, and our outside counsel on the transaction and our outside antitrust counsel participated in the meeting by telephone. Our antitrust counsel summarized the process of obtaining required antitrust approvals and discussed the likelihood of completing a merger transaction with Western and Company X from an antitrust perspective. Our corporate counsel summarized various terms of the merger agreement with Western for the board, and both counsel answered questions from members of the board regarding the merger. At the conclusion of the meeting, the board authorized Mr. Holliger to continue negotiating the merger agreement with Western and agreed to reconvene when the negotiations had concluded.

From August 22 through August 25, 2006, we and our counsel continued to work with Western and its counsel on the merger agreement, and Mr. Holliger and his counsel worked with Western and its counsel on the consulting agreement.

On August 23, 2006, our auditor, Deloitte & Touche LLP, and our corporate controller met with Western’s auditor, Ernst & Young LLP, regarding additional due diligence matters.

On August 25, 2006, the board of directors convened a special meeting by telephone to discuss the terms of the proposed merger agreement from Western. Also in attendance were representatives of Deutsche Bank, members of our senior management and our outside counsel. In advance of the meeting, a presentation by Deutsche Bank had been circulated to the board, including a fairness opinion. The representatives of Deutsche Bank gave their fairness opinion presentation to the board and answered the board’s questions. Deutsche Bank opined to our board that the merger consideration of $83.00 in cash per share of our common stock to be received by our stockholders pursuant to the merger agreement was fair, from a financial point of view as of such date and based upon and subject to the various qualifications, limitations, factors and assumptions set forth in its written opinion. The board discussed with counsel the final terms of the merger agreement. Our board then unanimously approved the merger and the merger agreement and agreed to recommend the adoption of the merger agreement and approval of the merger to our stockholders.

On August 26, 2006, the merger agreement was executed by Western and us and the consulting and non-competition agreement was executed by Western and Mr. Holliger. On August 26, 2006, Mr. Holliger contacted the chief executive officer of Company X and advised him that Giant was moving forward with another merger proposal. Mr. Holliger communicated that the critical issues that resulted in Giant’s board’s decision to proceed with Western’s proposal were the certainty of the all-cash nature of Western’s offer as compared to Company X’s cash and stock offer, and concerns regarding regulatory approvals for a merger with Company X.

The proposed transaction between Western and Giant was publicly announced in a joint Giant/Western press release on August 28, 2006.

Reasons for the Merger and Recommendation of the Board of Directors

In the course of reaching its decision to approve the merger agreement and the merger, our board consulted with senior management and our financial and legal advisors, and reviewed a significant amount of information and considered a number of factors, including the following:


	•	the value of the consideration to be received by our stockholders pursuant to the merger agreement, as well as the fact that the consideration will be paid in cash, which provides certainty of value to our stockholders compared to a transaction in which they would receive stock or other non-cash consideration;

	•	the $83.00 per share to be paid as the consideration in the merger is an all-time high price for our common stock and represents a 16% premium over the $71.79 closing price of our common stock on August 25, 2006 (the trading day prior to announcement of the transaction), a 19% premium over the closing price of our common stock on the last trading day before our board approved the merger, and a 19%, 21%, 26% and 24% premium over the volume weighted average closing price of our common stock over the 30-, 60-, 90- and 120-day periods, respectively, prior to August 25, 2006;

	•	the other non-binding proposal received by the board was for a higher stated price, but consisted of a significant stock component that the board believed involved uncertainty and risk to our stockholders, and that proposal had no committed financing, a longer lead time and possible hurdles to obtaining required regulatory approvals;

	•	the financial presentation of Deutsche Bank (including the assumptions and methodologies underlying the analyses in connection therewith) and the opinion of Deutsche Bank, which is attached to this proxy statement as Annex B and which you should read carefully in its entirety, that as of August 25, 2006, and based upon and subject to the various qualifications, limitations, factors and assumptions set forth therein, the merger consideration of $83.00 in cash per share of our common stock to be received by our stockholders pursuant to the merger agreement was fair to our stockholders from a financial point of view;

	•	the then-current financial market conditions, and historical market prices, volatility and trading information with respect to our common stock, including the possibility that if we remained a publicly-owned corporation, in the event of a decline in the market price of our common stock or the stock market in


		general, the price that might be received by holders of our common stock in the open market or in a future transaction might be less than the $83.00 per share cash price to be paid in the merger;


	•	historical and current information concerning our business, financial performance and condition, operations, technology, management and competitive position, and current industry, economic and market conditions, including our prospects if we were to remain an independent company;

	•	the terms and conditions of the merger agreement, including:


	•	the requirement that Western pay a deposit of $12.5 million at the time of execution of the merger agreement, and increase the deposit to $25 million if the merger has not been consummated by November 30, 2006 because the waiting period applicable to the consummation of the merger has not expired or been terminated under the HSR Act or any waiting period or any required consent under any applicable state or foreign competition or antitrust law has not expired or been obtained, which deposit will be payable to us if we terminate the merger agreement due to Western’s breach or if the merger has not been consummated by March 31, 2007 because the waiting period applicable to the consummation of the merger has not expired or been terminated under the HSR Act or any waiting period or any required consent under any applicable state or foreign competition or antitrust law has not expired or been obtained;

	•	the ability of the board, under certain circumstances, to furnish information to and conduct negotiations with a third party and, upon payment to Western of a termination fee of $37.5 million and up to $1 million in expense reimbursement, to terminate the merger agreement to accept a superior proposal;

	•	the board’s belief that the $38.5 million maximum aggregate fees and expenses payable to Western was reasonable in the context of termination fees that were payable in other comparable transactions and would not be likely to preclude another party from making a competing proposal; and

	•	the likelihood that the merger will be consummated, in light of the limited conditions to Western’s obligation to complete the merger, Western’s financial capability, and the absence of any financing condition to Western’s obligation to complete the merger;


	•	the terms of the commitment letter from Bank of America, N.A. and Banc of America Securities LLC to provide Western with funds to finance the transaction; and

	•	the merger consideration and other terms and conditions of the merger agreement resulted from arms-length bargaining between Giant and its representatives and Western and its representatives.

In the course of its deliberations, our board also considered a variety of risks and other countervailing factors, including:


	•	the risks and costs to us if the merger does not close, including the diversion of management and employee attention, employee attrition and the effect on business relationships;

	•	the restrictions that the merger agreement imposes on actively soliciting competing bids, and the fact that we would be obligated to pay the $37.5 million termination fee (and up to an additional $1 million in expense reimbursement) to Western under certain circumstances;

	•	the fact that Giant will no longer exist as an independent, stand-alone company, and our stockholders will no longer participate in the growth of Giant or in any synergies resulting from the merger;

	•	the fact that gains from an all-cash transaction would be taxable to our stockholders for U.S. federal income tax purposes as described in the section entitled “Material U.S. Federal Income Tax Consequences;”

	•	there is no assurance that all conditions to the parties’ obligations to complete the merger will be satisfied; and

	•	the interests of our officers and directors in the merger described under “— Interests of Certain Persons in the Merger.”

Our board concluded that these potentially negatives factors were substantially outweighed by the opportunity presented by the merger for our stockholders to monetize their Giant investment for $83.00 per share in cash within a relatively short period of time if the merger conditions were satisfied, which the board believed would maximize the immediate value of their shares and eliminate the risk that the inherent uncertainty affecting the refining industry and our future prospects could result in a diminution in the market value of their shares. Accordingly, the board concluded that the merger was in the best interests of our stockholders.

The foregoing discussion of the factors considered by our board is not intended to be exhaustive but does set forth the principal factors considered by the board. Our board collectively reached the unanimous conclusion to approve the merger agreement and the merger in light of the various factors described above and other factors that each member of our board felt were appropriate. In view of the wide variety of factors considered by our board in connection with its evaluation of the merger and the complexity of these matters, our board did not consider it practical, and did not attempt, to quantify, rank or otherwise assign relative weights to the specific factors it considered in reaching its decision and 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 ultimate determination of the board. Rather, our board made its recommendation based on the totality of information presented to and the investigation conducted by it. In considering the factors discussed above, individual directors may have given different weights to different factors.

After evaluating these factors and consulting with its legal counsel and its financial advisors, our board determined that the merger agreement was advisable and in the best interests of our stockholders. Accordingly, our board has unanimously approved the merger agreement and the merger. Our board recommends that you vote “FOR” the adoption of the merger agreement.

Opinion of Financial Advisor to the Board of Directors of Giant

The full text of Deutsche Bank’s opinion, which describes the various qualifications, factors, assumptions and limitations on the review undertaken by Deutsche Bank, is attached as Annex B to this proxy statement. Holders of our common stock are urged to, and should, read the Deutsche Bank opinion carefully and in its entirety. The Deutsche Bank opinion was addressed solely to our board of directors, was limited to the fairness, from a financial point of view, of the merger consideration to holders of our common stock as of the date of the opinion, and Deutsche Bank expressed no opinion as to the merits of the underlying decision by Giant to engage in the merger or as to how any holder of shares of Giant stock should vote with respect to the merger. The summary of the Deutsche Bank opinion set forth in this proxy statement is qualified in its entirety by reference to the full text of such opinion. The board of directors does not currently intend to seek an updated fairness opinion in connection with the merger.

In connection with its role as our financial advisor, and in arriving at its opinion, Deutsche Bank:


	•	reviewed certain publicly available financial and other information concerning Giant and Western;

	•	reviewed certain internal analyses, financial forecasts and other information relating to Giant prepared by our management;

	•	held discussions with certain of our senior officers and other representatives regarding the businesses and prospects of Giant;

	•	reviewed the reported prices and trading activity for Giant common stock;

	•	compared certain financial and stock market information for Giant with similar information for certain other companies Deutsche Bank considered relevant whose securities are publicly traded;


	•	reviewed the financial terms of certain recent business combinations which Deutsche Bank deemed relevant, to the extent publicly available;

	•	reviewed a draft dated August 25, 2006 of the merger agreement; and

	•	performed such other studies and analyses and considered such other factors as Deutsche Bank deemed appropriate.

Deutsche Bank did not assume responsibility for independent verification of, and did not independently verify, any information, whether publicly available or furnished to it, concerning Giant or Western, including, without limitation, any financial information, forecasts or projections considered in connection with the rendering of its opinion. Accordingly, for purposes of its opinion, Deutsche Bank, with our permission, assumed and relied upon the accuracy and completeness of all such information. Deutsche Bank did not conduct a physical inspection of any of the properties or assets, and did not prepare or obtain any independent evaluation or appraisal of any of the assets or liabilities of Giant or Western. With respect to the financial forecasts and projections made available to Deutsche Bank and used in its analyses, Deutsche Bank assumed, with our permission, that they were reasonably prepared on bases reflecting, as of the date of the opinion, the best estimates and judgments of our management as to the matters covered thereby. In rendering its opinion, Deutsche Bank expressed no view as to the reasonableness of such forecasts and projections or the assumptions on which they were based. Deutsche Bank’s opinion was necessarily based upon economic, market and other conditions as in effect on, and the information made available to it as of, the date of the opinion.

For purposes of rendering its opinion, Deutsche Bank assumed that the final terms of the merger agreement would not differ materially from the terms set forth in the draft that it reviewed. Deutsche Bank also assumed with our permission that, in all respects material to its analysis, the merger would be consummated in accordance with the terms of the merger agreement, without waiver, modification or amendment of any term, condition or agreement. Deutsche Bank further assumed that all material governmental, regulatory or other approvals and consents required in connection with the consummation of the merger would be obtained.

Deutsche Bank’s opinion was addressed to, and was for the use and benefit of, our board of directors, and was not a recommendation to holders of our common stock to approve the merger. Deutsche Bank’s opinion was limited to the fairness, from a financial point of view, of the merger consideration to holders of our common stock as of the date of the opinion, and Deutsche Bank expressed no opinion as to the merits of the underlying decision by Giant to engage in the merger or as to how any holder of shares of Giant stock should vote with respect to the merger.

Based upon and subject to the foregoing qualifications, limitations, factors and assumptions and those set forth in the opinion, Deutsche Bank was of the opinion that, as of August 25, 2006, the $83.00 in cash per share of our common stock to be received by the holders of our common stock was fair, from a financial point of view, to such holders.

In preparing its opinion to our board of directors, Deutsche Bank performed a variety of financial and comparative analyses, including those described below. The summary of Deutsche Bank’s analyses described below is not a complete description of the analyses underlying its opinion. The preparation of an opinion is a complex 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 and, therefore, an opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, Deutsche Bank made qualitative judgments as to the significance and relevance of each analysis and factor that it considered. Accordingly, Deutsche Bank 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, Deutsche Bank considered industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Giant. No company, transaction or business used in Deutsche Bank’s analyses as a comparison is identical to Giant 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 Deutsche Bank’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, Deutsche Bank’s analyses and estimates are inherently subject to substantial uncertainty.

Deutsche Bank’s opinion and financial analyses were only one of many factors considered by the board of directors in its evaluation of the proposed merger and should not be viewed as determinative of the views of the board of directors or management with respect to the merger or the merger consideration.

The following is a summary of the material financial analyses underlying Deutsche Bank’s opinion dated August 25, 2006, delivered to our board of directors in connection with the merger at a meeting of our board on August 25, 2006. The financial analyses summarized below include information presented in tabular format. In order to understand fully Deutsche Bank’s financial 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 analyses. Considering the data in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Deutsche Bank’s financial analyses.

Selected Public Company Analysis

Using publicly available information, Deutsche Bank reviewed the market values and trading multiples of the following publicly traded companies in the refining and related sectors, which Deutsche Bank deemed similar to Giant giving consideration to size, business mix and corporate structure (the “Selected Companies”):


	•	Valero Energy Corporation (“Valero”)

	•	Sunoco, Inc. (“Sunoco”)

	•	Tesoro Corporation (“Tesoro”)

	•	Western Refining, Inc. (“Western”)

Although the Selected Companies were compared to Giant for purposes of the analyses below, Deutsche Bank noted that no Selected Company is identical to Giant because of differences between the business mix, regulatory environment, operations and other characteristics of Giant and the Selected Companies. In evaluating the Selected Companies, Deutsche Bank made judgments and assumptions with regard to industry performance, general business, economic, regulatory, market and financial conditions and other matters, many of which are beyond the control of Giant, such as the impact of competition on Giant and on the industry generally, industry growth and the absence of any adverse material change on the financial condition and prospects of Giant, the industry or in the markets generally. Mathematical analysis (such as determining the average or median) is not in itself a meaningful method of using the data derived from the Selected Companies.

Deutsche Bank calculated the financial multiples and ratios below based on publicly available financial data as of August 23, 2006. The figures for Giant also assume that Giant received in full cash from insurance proceeds, net of taxes at the rate of 38.1%, and Deutsche Bank added this amount to Giant’s total enterprise value (defined as market capitalization plus total debt less cash and minority interest). Such estimates of additional pre-tax insurance proceeds and effective tax rate were provided to Deutsche Bank by our management.

Total Enterprise Value/EBITDA

The multiples analyzed on the basis of the Selected Companies included, among others, their respective total enterprise value as of August 23, 2006, divided by estimated 2006 earnings before interest, taxes, depreciation and amortization (“EBITDA”) and their respective total enterprise value divided by estimated 2007 EBITDA. The EBITDA estimates were the mean of estimates published by Institutional Brokers Estimate System (“IBES”), including analysts having published estimates during the months of July and August 2006 (“IBES consensus estimates”).

A summary of the market trading multiples of the Selected Companies and those multiples calculated for Giant are set forth below.


Selected Companies	2006 TEV/EBITDA			2007 TEV/EBITDA

Valero		4.2	x		4.6	x
Sunoco		4.6			4.9
Tesoro		3.5			4.2
Western		4.7			6.8
MINIMUM		3.5	x		4.2	x
MAXIMUM		4.7			6.8
MEDIAN		4.4			4.8

For purposes of its analysis, Deutsche Bank applied certain selected ranges of multiples based on the data above to our financial data. A selected range of 4.0x to 5.0x was applied to our estimated 2006 EBITDA to calculate an implied valuation range of $54.15 to $70.41. A selected range of 4.5x to 7.0x was applied to our estimated 2007 EBITDA to calculate an implied valuation range of $68.48 to $112.59. The EBITDA estimates were the IBES consensus estimates. Based upon these figures, Deutsche Bank calculated an average implied valuation range of $61.31 to $91.50.

Share Price/Earnings

The multiples analyzed on the basis of the Selected Companies also included, among others, their respective market capitalizations as of August 23, 2006, divided by estimated 2006 net income and their respective market capitalizations as of August 23, 2006, divided by estimated 2007 net income. The net income estimates were the IBES consensus estimates.

A summary of the market trading multiples of the Selected Companies and those multiples calculated for Giant are set forth below.


Selected Companies	2006 P/E			2007 P/E

Valero		6.8	x		8.0	x
Sunoco		9.0			10.2
Tesoro		6.5			8.1
Western		8.5			11.3
MINIMUM		6.5	x		8.0	x
MAXIMUM		9.0			11.3
MEDIAN		7.7			9.2

For purposes of its analysis, Deutsche Bank applied certain selected ranges of multiples based on the data above to our financial data. A selected range of 6.5x to 9.0x was applied to our estimated 2006 net income to calculate an implied valuation range of $55.17 to $75.78. A selected range of 8.0x to 11.5x was applied to our estimated 2007 net income to calculate an implied valuation range of $69.80 to $99.63. The net income estimates were the IBES consensus estimates. Based upon these figures, Deutsche Bank calculated an average implied valuation range of $62.48 to $87.70.

Analyst Price Targets

Deutsche Bank reviewed the range of publicly available equity research price targets for Giant as of August 23, 2006. This analysis resulted in a range of values of $80.00 to $88.00 per share. An analysis of the 12-month target price discounted at a rate of 12% resulted in a range of values from $71.43 to $79.46 per share.

Selected Precedent Transaction Analysis

Deutsche Bank reviewed and compared the proposed financial terms of the Giant/Western merger to corresponding publicly available financial terms and premiums of selected transactions. For this analysis, Deutsche

Bank reviewed certain corporate transactions from 2001 to the present in the energy industry’s refining and marketing sector and focused on the following transactions as of each transaction’s respective announcement date:


	•	February 2001 — Phillips Petroleum/Tosco Corporation

	•	May 2001 — Valero Energy Corporation/Ultramar Diamond Shamrock Corporation

	•	March 2003 — Frontier Oil Corporation/Holly Corporation (transaction did not close)

	•	April 2005 — Valero Energy Corporation/Premcor Inc.

	•	April 2005 — Marathon Oil Corporation/Ashland Inc.

	•	May 2006 — Alon USA Energy, Inc./Paramount Petroleum Corporation

Deutsche Bank derived from the selected transactions listed above a reference range of total enterprise value divided by last twelve months (“LTM”) EBITDA. The multiple of total enterprise value to LTM EBITDA ranged from 5.3x to 6.7x for the selected transactions. Deutsche Bank then applied that range to Giant’s LTM EBITDA, which resulted in an implied equity value range for Giant of $71.79 to $93.63 per share. Deutsche Bank also applied the range to Giant’s LTM EBITDA as adjusted for our management’s estimate of additional business interruption insurance proceeds to be received by Giant, which resulted in an implied equity value range for Giant of $85.09 to $110.45 per share.

No company or transaction utilized in the selected precedent transactions analysis is identical to Giant or the merger. The selected precedent transaction analysis was not adjusted for various issues of comparability, including the exceptional refining margin environment in the period following hurricanes Katrina and Rita. In evaluating the precedent transactions, Deutsche Bank made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Giant, such as the impact of competition on Giant and the industry generally, industry growth and the absence of any adverse material change in the financial condition and prospects of Giant or in the financial markets in general. Mathematical analysis, such as determining the average or median, or the high or the low, is not in itself a meaningful method of using comparable transaction data.

Discounted Cash Flow Analysis

Deutsche Bank performed a discounted cash flow analysis by adding (a) the present value of the estimated future free cash flows that Giant could generate over the period from June 30, 2006 to December 31, 2010 and (b) the present value of Giant’s “terminal value” at December 31, 2010, and then adjusting these aggregate values to equity values by subtracting net debt as of June 30, 2006. Free cash flows were calculated as after-tax earnings before interest and taxes plus non-cash expenses, less capital expenditures and less increases in net working capital. Terminal value refers to the estimated total value of Giant at the end of the forecast period, inclusive of any debt obligations at the time, based on the same set of management projections used for the remainder of the discounted cash flow analysis. Deutsche Bank’s analysis used financial projections provided by our management. Its discounted cash flow analysis applied a terminal EBITDA multiple range of 4.0x to 5.5x to estimated trailing (2010) EBITDA as of December 31, 2010. Deutsche Bank used a discount rate range to discount cash flows back to present value, reflecting Giant’s estimated average cost of capital, of 9.5% to 11.0%. Based on this analysis, Deutsche Bank estimated a discounted cash flow valuation range of $65.41 to $89.67 per share.

Premium over Share Price

Deutsche Bank reviewed the average premiums paid by purchasers in domestic merger and acquisition transactions since 2001. Deutsche Bank separately reviewed the premiums paid in cash transactions, stock transactions, hybrid transactions and all domestic merger and acquisition transactions collectively. Premiums were calculated relative to the target’s share price four weeks prior to the announcement of a transaction. This analysis indicated that the average premiums paid in transactions involving 100% cash consideration has been 30.4% since 2001 and 25.4% since 2004. Such analysis excluded transactions where the target was in the financial or real estate industries.

Utilizing the foregoing historical premiums analysis, Deutsche Bank reviewed the per share price of Giant stock four weeks prior to August 23, 2006 and applied a 20% and 35% premium to such average stock price. This analysis indicated a premium-adjusted per share price range of $83.80 to $94.27. Deutsche Bank also applied such 20% and 35% premium to the share price as of August 23, 2006. This analysis indicated a premium-adjusted per share price range of $83.66 to $94.12.

* * *

As described above, Deutsche Bank’s opinion to our board of directors was among many factors taken into consideration by our board of directors in making its determination to approve the merger agreement and recommend the merger. Such decisions were solely those of our board of directors. The opinion of Deutsche Bank was provided solely to our board of directors and does not constitute a recommendation to any person, including the holders of our common stock, as to how such person should vote or act on any matter related to the merger.

Pursuant to the terms of the Deutsche Bank engagement letter, we have agreed to pay certain fees to Deutsche Bank in connection with this engagement, a substantial portion of which is contingent upon the consummation of the merger. We have also agreed to reimburse Deutsche Bank for its expenses incurred in performing its services. In addition, we have agreed to indemnify Deutsche Bank and its affiliates (and their respective control persons, directors, officers, employees or agents) against certain liabilities and expenses arising out of Deutsche Bank’s engagement or any related transactions. No limitations were imposed on Deutsche Bank by us with respect to the investigations made or procedures followed by it in rendering its opinion.

Deutsche Bank is an affiliate of Deutsche Bank AG (which we will refer to with its affiliates as “DB Group”). One or more members of the DB Group have, from time to time, provided investment banking services to Western or its affiliates for which it has received compensation, including acting as joint book-running manager in an initial public offering of securities by Western, which closed in January 2006. It is anticipated that some of our indebtedness will be refinanced in connection with the merger and that proceeds of the refinancing will be used to discharge certain of that indebtedness which is held by one or more members of the DB Group. DB Group may provide investment and commercial banking services to Western in the future, for which DB Group would expect compensation. In the ordinary course of business, members of the DB Group may actively trade in the securities and other instruments and obligations of Giant and Western for their own accounts and for the accounts of their customers and, accordingly, may at any time hold long or short positions in those securities.

Delisting and Deregistration of Giant Common Stock

If the merger is completed, Giant common stock will be delisted from The New York Stock Exchange and deregistered under the Securities Exchange Act of 1934, as amended (which is referred to in this proxy statement as the Exchange Act), and Giant will no longer file periodic reports with the SEC, except as may be required with respect to any of Giant’s Senior Subordinated Notes that may remain outstanding after the effective time of the merger.

Interests of Certain Persons in the Merger

In considering the recommendation of our board with respect to the merger agreement, our stockholders should be aware that certain of our executive officers and directors have interests in the merger that may be different from, or in addition to, those of our stockholders generally. These interests may create potential conflicts of interest. Our board was aware of these potential conflicts of interest and considered them, among other matters, in reaching its decision to approve the merger agreement and the merger and to recommend that our stockholders vote in favor of adopting the merger agreement and approving the merger.

Consulting and Non-Competition Agreement between Fred L. Holliger and Western

As a condition to Western’s execution of the merger agreement, Fred L. Holliger, chairman of our board of directors and our chief executive officer, executed a consulting and non-competition agreement with Western that

will become effective at the effective time of the merger. The five-year consulting agreement provides for the following compensation to Mr. Holliger:


	•	annual compensation of $730,000 per year, plus expense reimbursement in accordance with Western’s policies applicable to executive employees of Western and medical benefits for Mr. Holliger and his eligible dependents on the basis available to other executive employees of Western;

	•	an aircraft allowance of up to $500,000 per year for each year during the term of the consulting agreement;

	•	access until December 31, 2008 to Mr. Holliger’s current office at our headquarters in Scottsdale, Arizona for so long as Western maintains such office facilities or a comparable alternative office space at a location reasonably acceptable to Mr. Holliger; and

	•	an administrative assistant at a cost not to exceed $100,000 annually, plus suitable administrative support and services, until December 31, 2008.

Western also has agreed that if any compensation payable to Mr. Holliger under the consulting and non-competition agreement is deemed to be an “excess parachute payment” under applicable income tax laws and therefore subject to excise tax, Western will pay Mr. Holliger the amount of the excise tax and any tax on the amount of the payment made.

Mr. Holliger’s agreement contains noncompetition provisions that restrict Mr. Holliger’s ability to compete with Western or solicit Western’s employees, customers or suppliers to terminate their relationship with Western for a period of two years following the termination of the consulting and non-competition agreement.

In addition to the payments provided for in the consulting and non-competition agreement, along with other of our executive officers, Mr. Holliger also is entitled to the payments under his existing Giant employment agreement upon a termination of his employment without cause after a change in control, as more fully described in the following section.

Employment Agreements with our Executive Officers

At the effective time of the merger, our executive officers are required to resign their positions as officers of Giant. Western may, but is not required to, offer employment to some or all of our executive officers on the same basis as our other employees. Our employment agreements with Fred Holliger, Morgan Gust, Mark Cox and Kim Bullerdick require us to make severance payments to them if their employment is terminated within three years following a change in control. The severance payments are equal to three times the executive’s base salary plus the average annual bonus paid to the executive for the three years prior to the fiscal year in which the termination occurs, but not less than 25% of the executive’s then base salary. In addition, if the severance payments are deemed to be “excess parachute payments” under applicable income tax laws and therefore subject to excise tax, Giant will pay the executive the amount of the excise tax and any tax on the amount of the payment made. The following table summarizes the severance payments payable to our executive officers under their employment agreements assuming the merger closes prior to December 31, 2006:


	Base		Average		Severance		Estimated		Total
Name	Salary		Bonus		Payment		Excise Tax(1)		Payments

Fred Holliger	$	650,000	$	923,333	$	4,720,000	$	2,809,259	$	7,529,259
Morgan Gust	$	450,000	$	563,333	$	3,040,000	$	1,662,118	$	4,702,118
Mark Cox	$	265,000	$	250,000	$	1,545,000	$	868,698	$	2,413,698
Kim Bullerdick	$	225,000	$	186,667	$	1,235,000	$	692,303	$	1,927,303


(1)		Estimated excise tax includes only the tax on the severance payments and the tax on proceeds from the restricted stock but excludes any additional excise tax payable as a result of any bonuses or other compensation or benefits to be received by the executive.

Merger Proceeds to be Received by Directors and Executive Officers

The following table summarizes the proceeds from shares of our common stock and/or stock options that will be received by our directors and executive officers in connection with the merger. Shares will be exchanged for the right to receive $83.00 per share in cash as described in this proxy statement, and options will be cancelled in exchange for a cash payment for each share subject to the option equal to the difference between $83.00 and the option exercise price per share, less applicable withholding taxes. See “The Merger Agreement - Stock Options.” All of our executives hold shares of our common stock that are “restricted” and vest over a period of five years. As a result of the merger, the vesting will accelerate, and the shares of restricted stock will be treated the same as the outstanding shares of common stock. See “The Merger Agreement — Restricted Stock.”

(2)		Mr. Bernitsky ceased to be a director of Giant on June 15, 2006.

(3)		Mr. Crow ceased to be an employee of Giant on May 5, 2006 and he has subsequently been employed by Western.

Indemnification of Officers and Directors

Western has agreed that, for a period of six years following the effective time of the merger, it and Giant as the surviving corporation of the merger will indemnify our current and former directors and officers against losses arising out of or pertaining to the fact that those persons were directors or officers of Giant. Western has also agreed to cause the surviving corporation to maintain in effect for six years after the merger a directors’ and officers’ liability insurance policy covering the current and former officers and directors with respect to matters existing or occurring at or prior to the effective time of the merger. Western is not, however, required to pay an annual premium for the insurance in excess of 200% of the last annual premium we paid. Giant has the right, with Western’s consent, to satisfy the insurance requirement by purchasing a six year “tail” insurance policy.

Employee Benefits

Western has agreed to provide certain benefits to our employees generally and has agreed to honor our obligations set forth in certain of our plans, which may benefit our officers in addition to our other employees. In addition, Western has agreed that bonuses will be paid pursuant to our existing 2006 Management Discretionary

Bonus Plan. The merger agreement also permits us to establish an additional bonus pool to be paid on the effective date of the merger to our employees in our board’s discretion. The maximum amount of bonuses that we are permitted to pay pursuant to both our 2006 Management Discretionary Bonus Plan and the additional bonus pool is $13 million. Our officers are expected to participate in the 2006 Management Discretionary Bonus Plan and the additional bonus pool, but the amounts payable to officers have not yet been determined by our board. Western will also continue in effect certain retiree medical coverage offered by Giant or provide equivalent coverage, subject to any terms and conditions of the coverage. Mr. Bullerdick also will be entitled to retiree medical coverage, subject to the terms and conditions of the coverage. See “The Merger Agreement — Benefit Arrangements.”

REGULATORY MATTERS

Mergers and acquisitions that may have an impact in the United States are subject to review by the Department of Justice and the Federal Trade Commission to determine whether they comply with applicable antitrust laws. Under the HSR Act, mergers and acquisitions that meet certain jurisdictional thresholds, such as the present transaction, may not be completed until the expiration of a waiting period that follows the filing of notification forms by both parties to the transaction with the Department of Justice and the Federal Trade Commission. The initial waiting period is 30 days, but this period may be shortened if the reviewing agency grants “early termination” of the waiting period, or it may be lengthened if the reviewing agency determines that an in-depth investigation is required and issues a formal request for additional information and documentary material. We and Western filed pre-merger notifications with the U.S. antitrust authorities pursuant to the HSR Act on September 7, 2006 and, in accordance with the merger agreement, requested “early termination” of the waiting period.

It is possible that any of the government entities with which filings are made may seek various regulatory concessions as conditions for granting approval of the merger. There can be no assurance that we will obtain the regulatory approvals necessary to complete the merger or that the granting of these approvals will not involve the imposition of conditions on completion of the merger or require changes to the terms of the merger. These conditions or changes could result in conditions to the merger not being satisfied. See “The Merger Agreement — Conditions to the Merger.”

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is a general discussion of certain material United States federal income tax consequences to our stockholders of the receipt of cash in exchange for shares of our common stock pursuant to the merger or upon the exercise of appraisal rights. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended, applicable current and proposed United States Treasury Regulations, judicial authority, and administrative rulings and practice, all of which are subject to change, possibly on a retroactive basis. This discussion assumes that the shares of our common stock are held as capital assets by a United States person (i.e., a citizen or resident of the United States or a domestic corporation). This discussion does not address all aspects of United States federal income taxation that may be relevant to a particular stockholder of ours in light of the stockholder’s personal investment circumstances, such as those stockholders of ours subject to special treatment under the United States federal income tax laws (for example, life insurance companies, dealers or brokers in securities or currencies, tax-exempt organizations, financial institutions, United States expatriates, foreign corporations and nonresident alien individuals), our stockholders who hold shares of our common stock as part of a hedging, “straddle,” conversion or other integrated transaction, or our stockholders who acquired their shares of our common stock through the exercise of employee stock options or other compensation arrangements. In addition, this discussion does not address any aspect of foreign, state or local or estate and gift taxation that may be applicable to our stockholders. We urge you to consult your own tax advisor to determine the particular tax consequences to you (including the application and effect of any state, local or foreign income and other tax laws) of the receipt of cash in exchange for shares of our common stock pursuant to the merger or upon the exercise of appraisal rights.

The receipt of cash in the merger or upon the exercise of appraisal rights will be a taxable transaction for United States federal income tax purposes. In general, for United States federal income tax purposes, a holder of shares of our common stock will recognize gain or loss equal to the difference between his or her adjusted tax basis in shares of our common stock converted to cash in the merger and the amount of cash received. Gain or loss will be calculated separately for each block of shares of our common stock (that is, shares of our common stock acquired at the same cost in a single transaction) converted to cash in the merger. If the shares of our common stock have been held for more than one year at the effective time of the merger, the gain or loss will be long-term capital gain or loss subject (in the case of stockholders who are individuals) to tax at a maximum United States federal income tax rate of 15%, and will be short-term capital gain or loss if, at the effective time of the merger, the shares of our common stock so converted to cash have been held for one year or less. The deductibility of a capital loss recognized on the exchange is subject to limitation.

Under the United States federal income tax backup withholding rules, unless an exemption applies, Western generally is required to and will withhold 28% of all payments to which a stockholder or other payee is entitled in the merger, unless the stockholder or other payee (1) is a corporation or comes within other exempt categories and demonstrates this fact or (2) provides its correct tax identification number (social security number, in the case of an individual, or employer identification number in the case of other stockholders), certifies under penalties of perjury that the number is correct (or properly certifies that it is awaiting a taxpayer identification number), certifies as to no loss of exemption from backup withholding, and otherwise complies with the applicable requirements of the backup withholding rules. Each stockholder of ours and, if applicable, each other payee, should complete, sign and return to the paying agent for the merger the substitute Form W-9 that the stockholders will receive with the letter of transmittal following completion of the merger in order to provide the information and certification necessary to avoid backup withholding, unless an applicable exception exists and is proved in a manner satisfactory to the paying agent. The exceptions provide that certain stockholders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. In order for a foreign individual to qualify as an exempt recipient, however, he or she must submit a signed Form W-8BEN, “Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding.” Backup withholding is not an additional tax. Generally, any amounts withheld under the backup withholding rules described above can be refunded or credited against a holder’s United States federal income tax liability, if any, provided that the required information is furnished to the United States Internal Revenue Service in a timely manner.

The foregoing discussion of certain material United States federal income tax consequences is included for general information purposes only and is not intended to be, and should not be construed as, legal or tax advice to any holder of shares of our common stock. We urge you to consult your own tax advisor to determine the particular tax consequences to you (including the application and effect of any state, local or foreign income and other tax laws) of the receipt of cash in exchange for shares of our common stock pursuant to the merger or upon the exercise of appraisal rights.

THE MERGER AGREEMENT

The following is a summary of the material terms of the merger agreement. Because the merger agreement is the primary legal document that governs the merger, we urge you to carefully read the complete text of the merger agreement for its precise legal terms and other information that may be important to you. The merger agreement is included as Annex A to this proxy statement.

Form of the Merger

If all of the conditions to the merger are satisfied or waived in accordance with the merger agreement, Merger Sub, a wholly-owned subsidiary of Western created solely for the purpose of engaging in the transactions contemplated by the merger agreement, will merge with and into Giant. The separate corporate existence of Merger Sub will cease, and Giant will survive the merger and will become a wholly-owned subsidiary of Western. We sometimes refer to Giant after the merger as the surviving corporation.

Structure and Effective Time

The merger agreement provides that we will complete the merger on the first business day after satisfaction or waiver of the conditions to the completion of the merger described in the merger agreement, or at such other time as we and Western may agree. We intend to complete the merger as promptly as practicable, subject to receipt of stockholder approval and all requisite regulatory approvals. We refer to the time at which the merger is completed as the effective time. Although we expect to complete the merger by the end of 2006, we cannot specify when, or assure you that, we and Western will satisfy or waive all conditions to the merger.

Certificate of Incorporation and Bylaws

At the effective time, the certificate of incorporation of the surviving corporation will be amended to read as the certificate of incorporation of Merger Sub, except that the name of Giant and its incorporator will continue, and the bylaws of Merger Sub will be the bylaws of the surviving corporation.

Board of Directors and Officers of the Surviving Corporation

All of our directors and officers are required to resign at the effective time, and the directors and officers of Merger Sub immediately prior to the merger will become the directors and officers of the surviving corporation following the merger.

Consideration to Be Received in the Merger

Upon completion of the merger, each share of our common stock issued and outstanding immediately prior to the effective time will be cancelled and converted into the right to receive $83.00 in cash, without interest and less applicable withholding taxes, other than shares held by stockholders who properly exercise and perfect their appraisal rights and any shares owned by us, Western or Merger Sub. Our stockholders are entitled to assert appraisal rights instead of receiving the merger consideration. For a description of these appraisal rights, please see “Appraisal Rights.”

Payment Procedures

Prior to the effective time of the merger, Western will appoint a paying agent that will make payment of the merger consideration to our stockholders. Western will deposit sufficient cash with the paying agent at or before the effective time of the merger in order to permit the payment of the merger consideration. Promptly after the effective time of the merger, the paying agent will mail to each holder of record of a certificate representing shares of our common stock a letter of transmittal and instructions explaining how to send his, her or its stock certificates to the paying agent. The paying agent will pay the merger consideration, less any withholding taxes required by law, to our stockholders promptly following the paying agent’s receipt of the stock certificate(s) and a properly completed letter of transmittal. In the case of book-entry or other uncertificated shares, the paying agent will pay the merger consideration, less any withholding taxes required by law, to our stockholders upon entry through a book-entry

transfer agent of the surrender of such shares on a book-entry account statement. No interest will be paid or accrued to our stockholders on the cash payable upon the surrender of stock certificates. Western is entitled to cause the paying agent to deliver to it any funds that have not been distributed within 6 months after the effective time of the merger. After that date, holders of certificates who have not complied with the instructions to exchange their certificates will be entitled to look only to Western for payment of the applicable merger consideration, without interest.

You should not send your Giant stock certificates to the paying agent until you have received transmittal materials from the paying agent. Please do not return your Giant stock certificates with the enclosed proxy.

If any of your stock certificates have been lost, stolen or destroyed, you will be entitled to obtain the merger consideration after you make an affidavit of that fact and, if required by Western, post a bond as Western may direct as indemnity against any claim that may be made against Western with respect to your lost, stolen or destroyed stock certificates.

Deposit

Concurrently with the execution of the merger agreement, Western deposited $12.5 million into an escrow account. This amount will be increased by Western to $25 million if the closing has not occurred by November 30, 2006 because the waiting period applicable to the consummation of the merger has not expired or been terminated under the HSR Act or any waiting period or any required consent under any applicable state or foreign competition or antitrust law shall not have expired or been obtained. The deposit is payable to us as liquidated damages if we terminate the merger agreement due to Western’s breach or if the merger has not been consummated by March 31, 2007 because the waiting period applicable to the consummation of the merger has not expired or been terminated under the HSR Act or any waiting period or any required consent under any applicable state or foreign competition or antitrust law has not expired or been obtained. At the effective time, the deposit will be paid over to the paying agent for distribution to our stockholders.

Restricted Stock

As a result of the merger, shares of our restricted stock that normally vest over a period of five years will vest immediately prior to the effective time of the merger, and the shares of restricted stock will be treated the same as the outstanding shares of common stock.

Stock Options

As a result of the merger, options to purchase our common stock that are outstanding as of the effective time of the merger will be cancelled. At the effective time of the merger, the holders of those options will become entitled to receive a cash payment in an amount equal to the number of shares subject to the option multiplied by the difference between $83.00 and the per share option exercise price, less the applicable withholding taxes.

Representations and Warranties

The merger agreement contains customary representations and warranties that we made to Western regarding, among other things:


	•	corporate matters, including due organization, power and qualification;

	•	authorization, execution, delivery and performance and the enforceability of the merger agreement and related matters;

	•	our capitalization;

	•	our subsidiaries;

	•	absence of conflicts with, or violations of, organizational documents, other agreements or instruments, applicable laws, or other obligations as a result of the merger;

	•	identification of required governmental filings and consents;

	•	absence of undisclosed liabilities;

	•	maintenance and effectiveness of disclosure controls and procedures, and absence of fraud involving management or other employees;

	•	litigation;

	•	absence of undisclosed brokers’ fees;

	•	our material contracts and key customer relationships;

	•	absence of undisclosed brokers’ fees;

	•	absence of intention to divest the surviving corporation’s assets; and

	•	availability of funds necessary for the merger, including the merger consideration.

Many of our representations and warranties are qualified by a material adverse effect standard. A “material adverse effect” means, with respect to Giant, any change, event or effect that, individually or taken together with other changes, events or effects, is materially adverse to the business, assets and liabilities (taken together), financial condition or results of operation of Giant and its subsidiaries on a consolidated basis or the ability of Giant to consummate the merger transaction, except that the following will not be considered to constitute a material adverse effect:


	•	any change resulting from (1) general political or economic conditions in the U.S. or other countries in which Giant or its subsidiaries operate, (2) factors generally affecting the petroleum refining industry, including changes in the price of crude oil and product prices, or (3) changes in laws or regulations affecting the


		petroleum refining industry generally (except, in each case, to the extent such change disproportionately affects Giant as compared to other companies in the petroleum refining industry); or


	•	any adverse change resulting from the pendency or announcement of the merger.

	•	conduct, and cause our subsidiaries to conduct, operations in the ordinary course of business;

	•	make or rescind any tax election, settle or compromise any tax liability for more than $100,000, amend any tax return, consent to any extension or waiver of the limitation period applicable to any tax liability, or change our method of accounting for tax purposes, or allow any of our subsidiaries to do the same;

In addition, during the same period, Western has agreed that, subject to certain exceptions, it will not do any of the following:


	•	authorize, propose, agree to, enter into or consummate any merger, consolidation or business combination transaction with any other entity, or permit any of its subsidiaries to do the same, if such transaction would materially delay the consummation of the merger, except pursuant to contractual commitments in effect on the date of the merger agreement;

	•	adopt a plan of complete or partial liquidation;

	•	take any action reasonably expected to materially delay or adversely affect the ability to obtain any governmental consent or approval, or the expiration of any applicable waiting period required to consummate the merger;

	•	acquire, or permit any of its subsidiaries to acquire, beneficial ownership of more than 4.9% of our shares, other than pursuant to the merger; or

	•	authorize, or commit or agree to take, any of the foregoing actions.

Debt Tender Offer

Western may request that we commence a cash tender offer to purchase all of our outstanding 11% Senior Subordinated Notes due 2012 and/or our outstanding 8% Senior Subordinated Notes due 2014 and a consent solicitation in order to amend certain covenants contained in the indentures to which such Senior Subordinated Notes are subject. In the event that Western requests that we commence the debt tender offer and consent solicitation, Western has agreed to pay directly to the dealer manager and the information agent all compensation owed to them under their respective agreements, whether or not the merger is consummated. If we commence the debt tender offer and consent solicitation but the merger is not consummated for any reason other than our breach, Western will reimburse us for our costs up to $250,000.

No Solicitation

The merger agreement provides that, until the effective time of the merger or the earlier termination of the merger agreement, neither Giant nor any of our officers, directors, employees, agents or representatives, including our investment bankers, attorneys and accountants, will solicit, initiate or encourage any acquisition proposal with a third party. In addition, the merger agreement required us to cease any discussions or negotiations with any third parties conducted prior to signing the merger agreement.

An acquisition proposal means any inquiry, proposal or offer with respect to a third-party tender offer, merger, consolidation, business combination, sale of assets, sale of stock or joint venture or similar transaction involving any of our assets or stock, or any acquisition of our stock, business or assets in a single transaction or series of related transactions.

Until such time as our stockholders adopt the merger agreement and approve the merger, however, we may provide information to and participate in discussions or negotiations with a third party if we receive an unsolicited bona fide acquisition proposal. Our board may take these actions only if:


	•	the third party has entered into a customary confidentiality agreement which would not prevent us from complying with our non-solicitation obligations to Western;

	•	our board determines in good faith, after consultation with outside counsel and our financial advisors, that it is reasonably likely that the acquisition proposal will result in a superior proposal; and

	•	our board determines in good faith after consultation with outside counsel that the failure to so act would be inconsistent with its fiduciary obligations under applicable law.

A superior proposal is an acquisition proposal that our board determines in good faith and after consultation with its financial advisors, taking into account all financial considerations, including the legal, financial, regulatory and other aspects of the acquisition proposal deemed relevant by our board, the identity of the third party making the acquisition proposal, and the conditions and prospects for completing the acquisition proposal, is reasonably likely to result in a transaction more favorable to our stockholders from a financial point of view than the merger.

We have agreed to promptly notify Western of our receipt of any acquisition proposal, request for information or inquiry with respect to any acquisition proposal, the material terms of any such acquisition proposal or inquiry, and the identity of the person making any such acquisition proposal or inquiry. We are also required to keep Western informed of any material changes, additions or adjustments to the terms of any such acquisition proposal or inquiry. We must also give Western written notice prior to our board participating in any such discussions or negotiations or provide any information to the third party.

Nothing in the merger agreement prohibits us from taking and disclosing a position to our stockholders with respect to a tender offer or from making any required disclosure to our stockholders if our board determines in good faith that failure to do so would be inconsistent with its obligations under applicable law.

Indemnification and Insurance

Western has agreed that, for a period of six years following the effective time of the merger, it and Giant as the surviving corporation will indemnify Giant’s current and former directors and officers against losses arising out of

or pertaining to the fact that those persons were directors or officers of Giant. Western has also agreed to cause the surviving corporation to maintain in effect for six years after the merger a directors’ and officers’ liability insurance policy covering the current and former officers and directors with respect to matters existing or occurring at or prior to the effective time of the merger. However, Western is not required to pay an annual premium for the insurance in excess of 200% of the last annual premium we paid. Giant has the right, with Western’s consent, to satisfy the insurance requirement by purchasing a six year “tail” insurance policy. For more information, please refer to “The Merger — Interests of Certain Persons in the Merger” and “— Indemnification of Officers and Directors.”

Benefit Arrangements

Western has agreed to honor, and cause its subsidiaries to honor, all employee benefit plans, contracts, agreements and binding commitments of Giant entered into prior to the date of the merger agreement. In addition, Western has agreed that, for a period of at least 12 months following the merger, the benefits taken as a whole offered under Western’s or the surviving corporation’s benefit plans, programs, policies and arrangements to continuing employees will be no less favorable than the benefits offered to such employees prior to the merger. Continuing employees are those of our employees who continue as employees of the surviving corporation or its subsidiaries following the merger. Western has agreed to give continuing employees full credit for prior service with us for purposes of eligibility and vesting under Western’s employee benefits plans and the determination of benefits levels under Western’s employee benefits plans relating to vacation or severance. In addition, Western will implement a severance plan with respect to any of our employees whose employment is terminated without cause within 12 months following the date of the merger, which will pay such employees two week’s compensation for each year of service with Giant and one week for each year of service with a company acquired by Giant, up to a maximum of one year’s salary.

Western has agreed to honor our binding commitments set forth in our ESOP Substitute Excess Deferred Compensation Benefit Plan. Western also has agreed to make the allocations under the Giant Industries, Inc. and Affiliated Companies Deferred Compensation Plan and mandatory matching and 3% supplemental contributions under the Giant Industries & Affiliated Companies 401(k) Plan due up to the date of the merger, to the extent not made by Giant prior to the date of the merger, in each case as set forth in the merger agreement.

Western has agreed that bonuses will be paid pursuant to our existing 2006 Management Discretionary Bonus Plan. The merger agreement also permits us to establish an additional bonus pool to be paid on the effective date of the merger to our employees in our board’s discretion. The maximum amount of bonuses that we are permitted to pay pursuant to our 2006 Management Discretionary Bonus Plan and the additional bonus pool is $13 million.

In addition, Western has agreed to pay any excise taxes imposed as a result of the merger on the compensation of employees who have employment agreements with Giant, including any tax on the amount of the payment made. Western will also continue in effect certain retiree medical coverage offered by Giant or provide equivalent coverage.

Conditions to the Merger

Our and Western’s obligations to effect the merger are subject to the satisfaction or waiver of the following conditions:


	•	our stockholders must have adopted the merger agreement and approved the merger;

	•	(1) the applicable waiting period under the HSR Act must have expired or been terminated and (2) any mandatory waiting period or required consent under any applicable state or foreign competition or antitrust law or regulation must have expired or been obtained, except in the case of clause (2) of this bullet point where the failure to observe such waiting period or obtain such consent would not reasonably be expected to delay or prevent the consummation of the merger or have a material adverse effect on the expected benefits of the transactions contemplated by the merger agreement to Western; and

	•	none of the parties to the merger agreement shall be subject to any decree, order or injunction of a court of competent jurisdiction, United States or foreign, which prohibits the consummation of the merger, and no


		statute, rule or regulation shall have been enacted by any governmental authority which prohibits or makes unlawful the consummation of the merger.

In addition, our obligation to effect the merger is subject to the satisfaction or waiver of the following conditions:


	•	the representations and warranties of Western in the merger agreement that are qualified by reference to materiality must be true and correct, and the representations and warranties of Western in the merger agreement that are not so qualified must be true and correct in all material respects; and

	•	Western and Merger Sub must have performed, in all material respects, their respective covenants and agreements required to be performed by them under the merger agreement.

In addition, the obligation of Western and Merger Sub to effect the merger are subject to the satisfaction or waiver of the following conditions:


	•	our representations and warranties in the merger agreement that are qualified by reference to materiality must be true and correct, and our representations and warranties in the merger agreement that are not so qualified must be true and correct in all material respects;

	•	we must have performed, in all material respects, all covenants and agreements required to be performed by us under the merger agreement;

	•	the consulting and non-competition agreement entered into as of August 26, 2006 between Fred L. Holliger and Western, which is to be effective as of the effective time of the merger, must remain in full force and effect;

	•	the number of dissenting shares shall not exceed 10% of the total number of shares of our common stock outstanding; and

	•	if Western has requested that we commence a tender offer and consent solicitation with respect to our outstanding 11% Senior Subordinated Notes due 2012 and/or our outstanding 8% Senior Subordinated Notes due 2014, then not less than a majority of the aggregate principal amount of the applicable Senior Subordinated Notes shall have been tendered and accepted for payment by us in accordance with the terms of the debt tender offer, and the indenture amendments applicable with respect to the applicable Senior Subordinated Notes shall become effective, in each case concurrently with the effectiveness of the merger.

Termination

The merger agreement may be terminated and the merger may be abandoned at any time prior to the effective time of the merger (notwithstanding any approval by our stockholders):


	•	by the mutual written consent of us and Western;

	•	by either us or Western, if:


	•	the merger has not consummated by March 31, 2007, provided that this right to terminate is not available to any party whose failure to fulfill in any material respect any obligation under the merger agreement has been a principal cause of or resulted in the failure of the merger to occur by March 31, 2007; or

	•	any governmental order, decree, ruling or action permanently restraining, enjoining or otherwise prohibiting the merger shall become final and non-appealable, provided that such party has complied with its obligations set forth in the merger agreement with respect to such matter;


	•	by Western, if:


	•	our board withdraws, modifies, withholds or changes its recommendation, in a manner adverse to Western, that our stockholders adopt the merger agreement, or recommends a superior proposal; or

	•	unless Western is also in breach, we breach or fail to perform any representation, warranty, covenant or agreement that would result in the failure of a condition to Western’s obligation to effect the merger being


		satisfied and which is not cured within 30 days after written notice of the breach or failure to perform is given to us;


	•	by us, if:


	•	prior to our stockholders adopting the merger agreement and approving the merger, our board withdraws its approval or recommendation of the merger with Western and recommends or declares advisable to our stockholders a superior proposal, provided that (1) we inform Western of our intent to effect such termination at least four business days prior to such termination, (2) we disclose the terms and conditions of the superior proposal and the identity of the third party, and provide copies of the documentation regarding the superior proposal, (3) we provide Western a reasonable opportunity during the four-business day period to adjust the terms and conditions of the merger agreement and to negotiate adjusted terms and conditions such that our board determines (in good faith, after consultation with nationally recognized outside legal counsel) that the third-party proposal is no longer considered a superior proposal, and (4) we pay Western a termination fee and reimburse Western for its expenses; or

	•	unless we are also in breach, Western breaches or fails to perform any representation, warranty, covenant or agreement that would result in the failure of a condition to our obligation to effect the merger being satisfied and which is not cured within 30 days after written notice of the breach or failure to perform is given to Western.

Termination Fee

The merger agreement obligates us to pay a termination fee to Western of $37.5 million, plus reimburse up to $1 million of Western’s expenses relating to the transactions contemplated by the merger agreement, if:


	•	we terminate the merger agreement prior to the special meeting because our board has withdrawn its approval or recommendation of the merger with Western and recommends or declares advisable to our stockholders a superior proposal, and Western elects not to adjust the terms and conditions of the merger agreement in a manner that would permit our board to conclude (in good faith, after consultation with nationally recognized outside legal counsel) that the third-party proposal is no longer a superior proposal; or

	•	the merger agreement is terminated by Western because our board withdraws, modifies, withholds or changes, in a manner adverse to Western, its recommendation or approval of the merger agreement or the merger, or recommends a superior proposal.

Amendment

The parties may amend the merger agreement at any time before or after adoption of the merger agreement by our stockholders. After stockholder approval has been obtained, however, the parties may not amend the merger agreement in a manner that by law requires further approval by our stockholders without obtaining such further approval.

APPRAISAL RIGHTS

Delaware law entitles the holders of shares of our common stock, who follow the procedures specified in Section 262 of the General Corporation Law of the State of Delaware, to have their shares appraised by the Delaware Court of Chancery and to receive “fair value” of these shares as of completion of the merger in place of the merger consideration, as determined by the court.

In order to exercise appraisal rights, a holder must demand and perfect the rights in accordance with Section 262.

The following description is intended as a brief summary of the material provisions of the Delaware statutory procedures required to be followed in order to perfect appraisal rights. This summary, however, is not a complete statement of all applicable requirements and is qualified in its entirety by reference to Section 262 of the General Corporation Law of the State of Delaware, the full text of which appears in Annex C to this proxy statement.

Section 262 requires that stockholders on the record date for the special meeting be notified not less than 20 days before the special meeting that appraisal rights will be available. A copy of Section 262 must be included with the notice. This proxy statement constitutes our notice to the holders of shares of our common stock of the availability of appraisal rights in connection with the merger in compliance with the requirements of Section 262. If you wish to consider exercising your appraisal rights, you should carefully review the text of Section 262 contained in Annex C to this proxy statement since failure to timely and properly comply with the requirements of Section 262 will result in the loss of your appraisal rights under Delaware law.

If you elect to demand appraisal of your shares, you must:


	•	be a holder of record of shares of our common stock;

	•	deliver to us a written demand for appraisal of your shares of Giant common stock before the vote of stockholders with respect to the merger agreement is taken;

	•	not vote in favor of the merger; and

	•	continuously hold your shares of our common stock through the completion of the merger.

Neither voting (in person or by proxy) against, abstaining from voting on nor failing to vote on the proposal to adopt the merger agreement will constitute a written demand for appraisal within the meaning of Section 262 of the General Corporate Law of the State of Delaware. The written demand for appraisal must be in addition to and separate from any proxy or vote. If the written demand for appraisal is made in accordance with the requirements of Delaware law, failure to vote against the merger (that is, abstaining) will not operate as a waiver of the stockholder’s appraisal rights.

Only a holder of record of shares of our common stock is entitled to assert appraisal rights for the shares of common stock registered in that holder’s name. A demand for appraisal should be executed by or on behalf of the holder of record, fully and correctly, as his, her or its name appears on his, her or its stock certificates, and must state that such person intends thereby to demand appraisal of his, her or its shares of our common stock in connection with the merger. If the shares of our common stock are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, execution of the demand should be made in that capacity, and if the shares of common stock are owned of record by more than one person, as in a joint tenancy and tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including two or more joint owners, may execute a demand for appraisal on behalf of a holder of record; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, the agent is agent for such owner or owners. A record holder, such as a broker who holds shares of our common stock as nominee for several beneficial owners, may exercise appraisal rights with respect to the shares of our common stock held for one or more beneficial owners while not exercising such rights with respect to the shares of our common stock held for other beneficial owners; in such case, however, the written demand should set forth the number of shares of our common stock as to which appraisal is sought and where no number of shares of our common stock is expressly mentioned, the demand will be presumed to cover all shares of our common stock which are held in the name of the record owner. Stockholders who hold their shares of our common stock in brokerage accounts or other nominee forms and who wish to exercise

appraisal rights are urged to consult with their brokers to determine the appropriate procedures for the making of a demand for appraisal by such a nominee.

All demands for appraisal should be made in writing and addressed to the Corporate Secretary of Giant at 23733 North Scottsdale Road, Scottsdale, Arizona 85255 before the stockholder vote on the merger agreement and the merger is taken at the special meeting. The demand must reasonably inform us of the identity of the holder and the intention of the holder to demand appraisal of his, her or its shares of common stock. If your shares of our common stock are held through a broker, bank, nominee or other third party, and you wish to demand appraisal rights you must act promptly to instruct the applicable broker, bank nominee or other third party to follow the steps summarized in this section.

Within 10 days after the effective date of the merger, the surviving corporation must give written notice of the date the merger became effective to each holder who has properly filed a written demand for appraisal and has not voted in favor of the merger. At any time within 60 days after the effective date, any holder who has demanded an appraisal has the right to withdraw the demand and to accept the cash payment specified by the merger agreement for his or her shares of our common stock. Within 120 days after the effective date, either the surviving corporation or any holder who has complied with the requirements of Section 262 and who is otherwise entitled to appraisal rights, may file a petition in the Delaware Court of Chancery (which we refer to as the Chancery Court) demanding a determination of the fair value of the shares of our common stock held by all holders entitled to appraisal. Neither Giant nor Western has any intention or obligation to file such a petition. Accordingly, the failure of a holder to file a petition in the Chancery Court demanding a determination of the fair value of the shares within 120 days after the effective time could nullify the holder’s previously written demand for appraisal. Within 120 days after the effective time of the merger, any holder of our common stock who has complied with the requirements for exercise of appraisal rights will be entitled, upon written request, to receive from the surviving corporation a statement setting forth the aggregate number of shares not voted in favor of the merger and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. The statement must be mailed to such holder within 10 days after a written request for the statement has been received by the surviving corporation or within 10 days after the expiration of the period for delivery of demands for appraisal, whichever is later.

If a petition for appraisal is duly filed by a holder and a copy of the petition is delivered to the surviving corporation, the surviving corporation will then be obligated, within 20 days after receiving service of a copy of the petition, to provide the Chancery Court with a duly verified list containing the names and addresses of all holders who have demanded an appraisal of their shares of our common stock and with whom agreements as to the value of their shares of our common stock have not been reached by the surviving corporation. After notice to dissenting holders of the time and place of the hearing of the petition, the Chancery Court is empowered to conduct such a hearing. At the hearing, the Chancery Court will determine those holders who have complied with Section 262 and who have become entitled to appraisal rights. The Chancery Court may require the holders who have demanded an appraisal for their shares of our common stock to submit their stock certificates to the Register in Chancery for notation of the pendency of the appraisal proceedings; and if any stockholder fails to comply with that direction, the Chancery Court may dismiss the proceedings as to that holder.

After determination of the holders entitled to appraisal of their shares of our common stock, the Chancery Court will appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger, together with a fair rate of interest, if any. When the fair value is determined, the Chancery Court will direct the payment of the value, with interest, if any, to the holders entitled to receive payment, upon surrender by such holders of the certificates representing the applicable shares of our common stock.

In determining fair value and the fair rate of interest, if any, the Chancery Court is required to take into account all relevant factors. You should be aware that the fair value of your shares of Giant common stock as determined under Section 262 could be more, the same, or less than the value that you are entitled to receive under the terms of the merger agreement.

Costs of the appraisal proceeding may be imposed upon the parties participating in the appraisal proceeding by the Chancery Court as the Chancery Court deems equitable in the circumstances. Upon the application of a holder, the Chancery Court may order all or a portion of the expenses incurred by any holder in connection with the

appraisal proceeding, including, without limitation, reasonable attorneys’ fees and the fees and expenses of experts, to be charged pro rata against the value of all shares of our common stock entitled to appraisal.

Any holder who has demanded appraisal rights will not, from and after the effective date of the merger, be entitled to vote shares of Giant common stock subject to that demand for any purpose or to receive payments of dividends or any other distribution with respect to those shares, other than dividends or other distributions payable to our stockholders of record at a date prior to the effective date of the merger; however, if no petition for appraisal is filed within 120 days after the effective date of the merger, or if the holder delivers a written withdrawal of his or her demand for appraisal and an acceptance of the merger within 60 days after the effective date of the merger, then the right of that holder to appraisal will cease and that holder will be entitled to receive the cash payment for his, her or its shares of our common stock pursuant to the merger agreement. Any withdrawal of a demand for appraisal made more than 60 days after the effective date of the merger may only be made with the written approval of the surviving corporation. Notwithstanding the foregoing, no appraisal proceeding in the Chancery Court will be dismissed without the approval of the Chancery Court and may be subject to conditions the Chancery Court deems just.

In view of the complexity of Section 262, holders of shares of our common stock who may wish to pursue appraisal rights should promptly consult their legal advisors.

The Giant Stock Fund is composed primarily of our common stock and a small amount (approximately 5%) of short-term money market funds. Ownership in the Giant Stock Fund is measured in units rather than shares of common stock. Each 401(k) participant has the right to direct the 401(k) trustee to vote the participant’s proportionate share of the common stock underlying the units in the Giant Stock Fund. We determine a participant’s proportionate share by multiplying the total number of underlying shares held in the Giant Stock Fund by a fraction, the numerator of which is the number of underlying shares allocated to the participant and the denominator of which is the number of underlying shares allocated to all participants’ accounts as of the record date. The 401(k) trustee and the participants have shared dispositive power with respect to the underlying shares allocated to a participant’s account.

(3)		5,500 shares are held in a trust in which Mr. Gust and his spouse are settlors, co-trustees and beneficiaries.

RECITALS

WHEREAS, the respective boards of directors of each of Parent, Merger Sub and the Company have approved and declared advisable this Agreement and the merger of Merger Sub with and into the Company (the “Merger”), whereby each share of capital stock of the Company issued and outstanding prior to the Merger will be converted into the right to receive the Per Share Merger Consideration provided for herein;

WHEREAS, the board of directors of the Company has determined that the Merger is fair to and in the best interests of the Company and its stockholders; and

WHEREAS, the Company, Parent and Merger Sub desire to make certain representations, warranties, covenants and agreements in connection with this Agreement;

NOW, THEREFORE, in consideration of the foregoing, and of the representations, warranties, covenants and agreements contained herein, the parties agree as follows:

ARTICLE 1

THE MERGER

Section 1.1 THE MERGER. Subject to the terms and conditions of this Agreement, at the Effective Time (as defined in Section 1.3), Merger Sub shall be merged with and into the Company in accordance with this Agreement, and the separate corporate existence of Merger Sub shall thereupon cease. The Company (sometimes hereinafter referred to as the “Surviving Corporation”) shall be the surviving corporation in the Merger and shall be a wholly-owned, direct subsidiary of Parent. The Merger shall have the effects specified in the Delaware General Corporation Law (“DGCL”).

Section 1.2 THE CLOSING.

The Merger shall become effective upon the filing of the Certificate of Merger with the Secretary of State of the State of Delaware in accordance with the DGCL, or at such later time that the parties hereto shall have agreed upon and designated in such filing as the effective time of the Merger (the “Effective Time”).

Section 1.4 CERTIFICATE OF INCORPORATION. At the Effective Time, the certificate of incorporation of the Company (other than the provisions of the certificate of incorporation of the Company setting forth the name of the Company and the incorporator of the Company, which shall not be amended), shall be amended to read as the certificate of incorporation of Merger Sub in effect immediately prior to the Effective Time and, as so amended, shall be the certificate of incorporation of the Surviving Corporation, until duly amended in accordance with applicable law.

A-4

Section 1.5 BYLAWS. The bylaws of Merger Sub in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Corporation, until duly amended in accordance with applicable law.

Section 1.6 DIRECTORS AND OFFICERS. The directors and officers of the Surviving Corporation shall consist of the directors and officers of Merger Sub, as it existed immediately prior to the Effective Time, until changed in accordance with applicable law.

ARTICLE 2

CONVERSION OF THE COMPANY SHARES

Section 2.1 EFFECT ON CAPITAL STOCK. At the Effective Time, the Merger shall have the following effects on the capital stock of the Company and Merger Sub, without any action on the part of the holder of any capital stock of the Company or Merger Sub:

(a) Conversion of the Company Shares. Each share of common stock, $0.01 par value per share, of the Company (each a “Share”) issued and outstanding immediately prior to the Effective Time (other than any Shares (i) held by Parent, Merger Sub or any other wholly-owned Subsidiary (as defined in Section 8.9) of Parent, (ii) in the treasury of the Company or (iii) held by any wholly-owned Subsidiary of the Company, which Shares, by virtue of the Merger and without any action on the part of the holder thereof, shall be cancelled and shall cease to exist with no payment being made with respect thereto, and other than Dissenting Shares (as defined in Section 2.3)) shall automatically be converted into the right to receive US$83.00, without interest, in cash (the “Per Share Merger Consideration”). The aggregate amount of the Per Share Merger Consideration in respect of all Shares entitled thereto is referred to as the “Merger Consideration.” The holder of a certificate that represented Shares (a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive, upon surrender of such Certificate, the Per Share Merger Consideration to which such holder is entitled pursuant to this Section 2.1(a).

(b) Cancellation of Shares. As of the Effective Time, all Shares that are issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares) shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a Certificate shall cease to have any rights with respect thereto, except the right to receive a cash amount equal to the Per Share Merger Consideration multiplied by the number of Shares formerly represented by the Certificate, to be paid in consideration therefor upon surrender of such Certificate in accordance with Section 2.2.

(c) Merger Sub. At the Effective Time, each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation, and the Surviving Corporation shall thereby become a wholly-owned, direct Subsidiary of Parent.

Section 2.2 DEPOSIT; EXCHANGE OF CERTIFICATES

(a) Deposit. On the first business day after the date hereof, Parent shall deposit $12,500,000 (the “Deposit”) into an escrow account with Wells Fargo Bank, N.A. (the “Escrow Agent”) pursuant to an Escrow Agreement of even date among the Company, Parent and the Escrow Agent (the “Escrow Agreement”). The Deposit shall be increased to $25,000,000 if the Closing has not occurred on or before November 30, 2006 because the condition set forth in Section 6.1(b) has not been satisfied. As provided in the Escrow Agreement, the Escrow Agent shall pay the Deposit to the Paying Agent (as defined below) to be applied towards the Merger Consideration at the Closing, or if this Agreement is terminated, to the Company or Parent, as the case may be, as provided in Section 7.5(b).

(b) Paying Agent; Payment of Merger Consideration. Prior to the Closing Date, Parent shall appoint a bank or trust company to act as paying agent (the “Paying Agent”) for the payment of the Merger Consideration. On or before the Closing Date, Parent shall deposit (or cause to be deposited) the Merger Consideration (such cash consideration being hereinafter referred to as the “Merger Fund”) with the Paying Agent. The Merger Fund shall not include Per Share Merger Consideration for any Dissenting Shares, and the holders of Dissenting Shares shall not be entitled to receive payment of the Per Share Merger Consideration related to such Dissenting Shares from the Merger Fund. The Merger Fund shall not be used for any other purpose.

A-5

(c) Exchange Procedures. Promptly after the Effective Time (but not later than five (5) business days after the date on which the Effective Time occurs), Parent shall cause the Paying Agent to mail or deliver to each Person (as defined in Section 8.9) who was, at the Effective Time, a holder of record of Shares and whose Shares are being converted into the right to receive the Per Share Merger Consideration pursuant to this Article 2 a letter of transmittal (which shall be in customary form and specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent and shall otherwise be in a form and have such other provisions as Parent may reasonably specify) containing instructions for use by holders of Certificates to effect the exchange of their Certificates for the Per Share Merger Consideration as provided herein. As soon as practicable after the Effective Time, each holder of an outstanding Certificate or Certificates shall, upon surrender to the Paying Agent of such Certificate or Certificates and such letter of transmittal duly executed and completed in accordance with the instructions thereto (together with such other documents as the Paying Agent may reasonably request) and acceptance thereof by the Paying Agent (or, if such Shares are held in book-entry or other uncertificated form, upon the entry through a book-entry transfer agent of the surrender of such Shares on a book-entry account statement (it being understood that any references herein to “Certificates” shall be deemed to include references to book-entry account statements relating to the ownership of Shares)), be entitled to an amount of cash (payable by check) equal to the Per Share Merger Consideration multiplied by the number of Shares formerly represented by such Certificate or Certificates. The Paying Agent shall accept such Certificates upon compliance with such reasonable terms and conditions as the Paying Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. If cash is to be remitted to a Person other than the Person in whose name the Certificate surrendered for exchange is registered, it shall be a condition of such exchange that the Certificate so surrendered shall be properly endorsed, with signature guaranteed, or otherwise in proper form for transfer and that the Person requesting such exchange shall pay to the Paying Agent any transfer or other Taxes (as defined in Section 8.9) required by reason of the payment of the Per Share Merger Consideration to a Person other than the registered holder of the Certificate so surrendered, or shall establish to the satisfaction of the Paying Agent that such Tax either has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2(c), at any time after the Effective Time, each Certificate shall be deemed to represent only the right to receive the Per Share Merger Consideration upon such surrender. No interest shall be paid or shall accrue on any cash payable as Per Share Merger Consideration.

(d) No Further Ownership Rights. All cash paid upon the surrender for exchange of Certificates formerly representing Shares in accordance with the terms of this Article 2 shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares formerly represented by such Certificates, and, after the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Shares which were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for transfer, then they shall be cancelled and exchanged as provided in this Article 2.

(e) Investment of Merger Fund. The Paying Agent shall invest the Merger Fund as directed by Parent, provided that no gain or loss thereon shall affect the amounts payable to the Company’s stockholders pursuant to Section 2.1(a).

(f) Termination of Merger Fund. Any portion of the Merger Fund which remains undistributed to the holders of Certificates for six (6) months after the Effective Time shall be delivered to Parent, and any holders of Certificates who have not theretofore complied with this ARTICLE 2 shall thereafter look only to Parent for payment of the Merger Consideration, subject to abandoned property, escheat and similar laws. Notwithstanding the foregoing, none of Parent, Surviving Corporation, the Paying Agent or any other Person shall be liable to any holder of a Certificate with regard to Per Share Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(g) Lost, Stolen or Destroyed Certificates. In the event 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, the posting by such Person of a bond in such reasonable amount as Parent may require as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will distribute such Per Share Merger Consideration payable pursuant to this Agreement.

A-6

(h) Withholding. Parent or the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares such amounts as Parent or the Paying Agent is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), the Treasury Regulations promulgated thereunder (the “Treasury Regulations”) or under any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by Parent or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made by Parent or the Paying Agent.

Section 2.3 APPRAISAL RIGHTS. The Shares outstanding immediately prior to the Effective Time and held by a holder who neither shall have voted in favor of the Merger nor shall have consented thereto in writing and who shall have properly demanded appraisal for such Shares in accordance with the DGCL are referred to herein as “Dissenting Shares”. Notwithstanding any other provision of this Agreement to the contrary, Dissenting Shares shall not be converted into a right to receive the Per Share Merger Consideration, and instead shall be entitled only to such rights as are provided under the DGCL. If, after the Effective Time, such holder fails to perfect, withdraws or loses its right to appraisal, such Shares shall no longer be deemed to be Dissenting Shares and shall be treated as if they had been converted at the Effective Time into the right to receive the Per Share Merger Consideration. The Company shall give Parent prompt notice of any demands received by the Company for appraisal of such Shares. Except as required by applicable law or with the prior written consent of Parent, the Company shall not make any payment with respect to, or settle or offer to settle, any such demands.

Section 2.4 ADJUSTMENTS. In the event that prior to the Effective Time, there shall have been declared or effected a stock split, subdivision, reverse stock split, consolidation and division, stock dividend or stock distribution (including any dividend, or distribution, of securities convertible into Shares), reorganization, recapitalization, reclassification or similar event made with respect to the Shares, the Per Share Merger Consideration shall be adjusted to reflect fully the appropriate effect of such event.

Section 2.5 EFFECT OF THE MERGER ON EQUITY AWARDS.

(a) Stock Options. The board of directors of the Company (or the appropriate committee thereof) shall adopt such resolutions or take such other actions as shall be required to cause each Stock Option (as defined in Section 3.3) to terminate and be cancelled at the Effective Time, with each holder of a Stock Option entitled to receive from Parent at the Effective Time a Cash Amount in settlement of such Stock Option. The “Cash Amount” shall be equal to the net amount of (i) the product of (A) the excess, if any, of the Per Share Merger Consideration over the exercise price per share of such Stock Option, multiplied by (B) the number of shares subject to such Stock Option, less (ii) any applicable withholdings for Taxes. If the exercise price per share of any Stock Option equals or exceeds the Per Share Merger Consideration, the Cash Amount therefor shall be $0.01 per share. Payment of the Cash Amount shall be communicated to each holder of Stock Options in a written notice from the Company that has been approved by Parent stating that, upon acceptance of the Cash Amount, such holder understands that no further payment is due to such holder on account of any Stock Options and all of such holder’s rights under such Stock Options have terminated. All amounts payable to a holder of an outstanding Stock Option shall be rounded to the nearest cent.

(b) Restricted Stock. The Board of Directors of the Company (or the appropriate committee thereof) shall adopt such resolutions or take such other actions as shall be required to cause all restrictions on the then-outstanding shares of Restricted Stock (as defined in Section 3.3) to lapse immediately prior to the Effective Time. Each holder of Restricted Stock shall be treated as a holder of Shares issued and outstanding immediately prior to the Effective Time.

(c) Cancellation. As of the Effective Time, except as provided in this Section 2.5, all rights under any Stock Options and any provision of the Company’s stock option plans providing for the issuance and grant of any other interest in respect of the capital stock of the Company shall be cancelled. The Company shall use its reasonable best efforts to ensure that, as of and after the Effective Time, except as provided in this Section 2.5, no Person shall have any rights with respect to securities of the Company, the Surviving Corporation or any Subsidiary thereof.

(d) Section 16 Exemption. Prior to the Effective Time, the Company and Parent shall use their reasonable best efforts to cause the transactions contemplated by this Section 2.5 and any other dispositions of equity securities

A-7

of the Company (including derivative securities) in connection with this Agreement by each individual who is subject to Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) with respect to the Company to be exempt under Rule 16b-3 of the Exchange Act.

The Company has all requisite corporate power and authority to own, operate and lease its properties and to carry on its business as now conducted. The copies of the Company’s restated certificate of incorporation and bylaws previously made available to Parent are true and correct and contain all amendments as of the date hereof.

organization, has the corporate or limited liability company power and authority to own, operate and lease its properties and to carry on its business as it is now being conducted, and is duly qualified to transact business and is in good standing (where applicable) in each jurisdiction in which the ownership, operation or lease of its property or the conduct of its business requires such qualification, except for jurisdictions in which such failure to be so qualified or to be in good standing has not had and would not reasonably be expected to have a Material Adverse Effect. All of the outstanding shares of capital stock of, or other ownership interests in, each of the Company’s Subsidiaries is duly authorized, validly issued, fully paid and nonassessable, and is owned, directly or indirectly (as specified on Schedule 3.4 of the Disclosure Letter), by the Company free and clear of all Liens (as defined in Section 3.6), except to the extent of any Liens set forth on Schedule 3.4 of the Disclosure Letter.

(a) The Company agrees that, from the date hereof until the earlier of the Effective Time or the termination of this Agreement, it (i) will not (and the Company will not permit its officers, directors, employees, agents or representatives, including any investment banker, attorney or accountant retained by the Company, to) solicit, initiate or encourage (including by way of furnishing non-public information) any inquiry, proposal or offer (including any proposal or offer to its stockholders) with respect to a third party tender offer, merger, consolidation, business combination, sale of assets, sale of stock or joint venture or similar transaction involving any assets or class of capital stock of the Company, or any acquisition of the capital stock of the Company or a business or assets (other than sales of current assets in the ordinary course of business) of the Company in a single transaction or a series of related transactions, or any combination of the foregoing (any such proposal, offer or transaction being hereinafter referred to as an ‘‘Acquisition Proposal”) or engage in any discussions or negotiations concerning an Acquisition Proposal; and (ii) will immediately cease and cause to be terminated any existing discussions or negotiations with any third parties conducted heretofore with respect to any Acquisition Proposal; provided that, subject to Section 7.3(b), nothing contained in this Agreement shall prevent the Company or its board of directors from (A) taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) under the Exchange Act or making any disclosure to the Company’s stockholders if the Company’s board of directors determines in good faith that the failure to make such disclosure would result in a breach of its fiduciary duties under applicable law or (B) providing information (pursuant to a confidentiality agreement in reasonably customary form and which does not contain terms that prevent the Company from complying with its obligations under this Section 5.2) to or engaging in any negotiations or discussions with any Person or group who has made an unsolicited bona fide Acquisition Proposal with respect to all of the outstanding shares of capital stock of the Company or all or substantially all of the assets of the Company if, with respect to the actions set forth in clause (B), (x) the Company’s board of directors determines in good faith and after consultation with its financial advisors, taking into account all financial considerations, including the legal, financial, regulatory and other aspects of the Acquisition Proposal deemed relevant by the Company’s board of directors, the identity of the Person making the Acquisition Proposal, and the conditions and prospects for completing the Acquisition Proposal, that such Acquisition Proposal is reasonably likely to result in a transaction more favorable to the holders of the Shares from a financial point of view than the Merger (a “Superior Proposal”) and (y) the board of directors of the Company, after consultation with its outside legal counsel, determines in good faith that the failure to do so would result in a breach of its fiduciary obligations under applicable law.

(b) The Company agrees that it will notify Parent promptly (and in any event within 24 hours) if any proposal or offer relating to or constituting an Acquisition Proposal is received by, any information is requested from, or any discussions or negotiations are sought to be initiated or continued with, the Company or any of its officers, directors, employees, agents or representatives. In connection with such notice, the Company shall indicate the identity of the Person or group making such request or inquiry or engaging in such negotiations or discussions and the material terms and conditions of any Acquisition Proposal.

Prior to taking any action referred to in clause (B) of the proviso of Section 5.2(a)(i), if the Company intends to participate in any such discussions or negotiations or provide any such information to any such third party, the Company shall give prior written notice to Parent.

(c) Nothing in this Section 5.2 shall permit the Company to enter into any agreement with respect to an Acquisition Proposal during the term of this Agreement, it being agreed that, during the term of this Agreement, the Company shall not enter into any agreement with any Person that provides for, or in any way facilitates, an Acquisition Proposal, other than a confidentiality agreement and/or standstill agreement permitted under Section 5.2(a)(i) in reasonably customary form and which does not contain terms that prevent the Company from complying with its obligations under this Section 5.2.

(v) furnish counsel to the other party with copies of all correspondence, filings and communications (and memoranda setting forth the substance thereof) between them and their affiliates and their respective representatives on the one hand, and any Governmental Authorities or members of their respective staffs on the other hand, with respect to this Agreement and the Merger; and

(vi) furnish the other party with such necessary information and reasonable assistance as such other party and its respective affiliates may reasonably request in connection with their preparation of necessary filings, registrations or submissions of information to any Governmental Authorities, including any filings necessary or appropriate under the provisions of the HSR Act; provided that if the provisions of the HSR Act would prevent a party from disclosing such information to the other party, then such information may be disclosed to such party’s counsel.

(b) Without limiting Section 5.4(a), Parent and the Company shall:

(i) each use its reasonable best efforts to respond promptly to any requests for additional information made by the Department of Justice (“DOJ”) or the Federal Trade Commission (“FTC”), and to cause the waiting periods under the HSR Act to terminate or expire at the earliest possible date after the date of filing;

(iv) each use reasonable best efforts to avoid or eliminate each and every impediment under any antitrust, competition or trade regulation law that may be asserted by any Governmental Authority with respect to the Merger so as to enable the Closing to occur as soon as reasonably possible (and in any event no later than 60 days following the termination of all applicable waiting periods under the HSR Act, unless the parties are in litigation with the government, in which case at the conclusion of such litigation); provided that, notwithstanding anything to the contrary in this Section 5.4 or the remainder of this Agreement, neither Parent nor any of its Subsidiaries shall be required to agree to any divestitures, licenses, hold separate arrangements or similar matters, including covenants affecting business operating practices.

Notwithstanding the foregoing, the Company shall not be required to provide any information which it reasonably believes it may not provide to any other party by reason of applicable law, rules or regulations, which the Company reasonably believes constitutes information protected by attorney/client privilege, or which it is required to keep confidential by reason of contract or agreement with third parties. The parties hereto will make reasonable and appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply. Parent will not, and will cause its representatives not to, use any information obtained pursuant to this Section 5.5 for any purpose unrelated to the consummation of the transactions contemplated by this Agreement.

Section 5.8 INDEMNIFICATION AND INSURANCE.

(a) From and after the Effective Time, Parent and the Surviving Corporation shall indemnify, defend and hold harmless to the fullest extent permitted under applicable law each person who is immediately prior to the Effective Time, or has been at any time prior to the Effective Time, an officer or director of the Company and each person who immediately prior to the Effective Time is serving or prior to the Effective Time has served at the request of the Company as a director, officer, trustee or fiduciary of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise, including the members of the Administrative Committee of the Company Plans (individually, an “Indemnified Party” and, collectively, the “Indemnified Parties”) against all losses, claims, damages, liabilities, costs or expenses (including attorneys’ fees), judgments, fines, penalties and amounts paid in settlement in connection with any claim, action, suit, proceeding or investigation arising out of or pertaining to acts or omissions, or alleged acts or omissions, by them in their capacities as such, whether commenced, asserted or claimed before or after the Effective Time. In the event of any such claim, action, suit, proceeding or investigation (an “Action”), (i) Parent and the Surviving Corporation shall pay, as incurred, the fees and expenses of counsel selected by the Indemnified Party, which counsel shall be reasonably acceptable to Parent, in advance of the final disposition of any such Action to the fullest extent permitted by applicable law, and, if required, upon receipt of any undertaking required by applicable law, and (ii) Parent and the Surviving Corporation shall cooperate in the defense of any such matter; provided, however, neither Parent nor the Surviving Corporation shall be liable for any settlement effected without their written consent (which consent shall not be unreasonably withheld or delayed), and provided further that neither Parent nor the Surviving Corporation shall be obligated pursuant to this Section 5.8(a) to pay the fees and disbursements of more than one counsel for all Indemnified Parties in any single Action, unless, in the good faith judgment of any of the Indemnified Parties, there is or may be a conflict of interests between two or more of such Indemnified Parties, in which case there may be separate counsel for each similarly situated group. In no event shall Parent or the Surviving Corporation be required to indemnify any of the Indemnified Parties or advance any expenses on behalf of any of the Indemnified Parties pursuant to this Section 5.8 to any greater extent than the Company, as applicable, would have been required to so indemnify or

A-24

advance expenses pursuant to the restated certificate of incorporation or bylaws of the Company or contractual indemnification agreements binding on the Company (including board resolutions relating to the Administrative Committee of the Company Plans) which such contractual indemnification agreements and board resolutions are disclosed on Schedule 5.8(a) of the Disclosure Letter, each as in existence on the date hereof.

(b) The parties agree that the rights to indemnification hereunder, including provisions relating to advances of expenses incurred in defense of any action or suit, in the restated certificate of incorporation, bylaws and any board resolutions relating to the Administrative Committee of the Company Plans and indemnification agreement of the Company with respect to matters occurring through the Effective Time, shall survive the Merger and shall continue in full force and effect for a period of six years from the Effective Time; provided, however, that all rights to indemnification and advancement of expenses in respect of any Action pending or asserted or claim made within such period shall continue until the disposition of such Action or resolution of such claim.

(c) For a period of six years after the Effective Time, Parent shall, or shall cause the Surviving Corporation to, maintain or cause to be maintained officers’ and directors’ liability insurance (“D&O Insurance”) covering the Indemnified Parties who are or at any time prior to the Effective Time were covered by the Company’s existing D&O Insurance policies on terms substantially no less advantageous to such Indemnified Parties than such existing D&O Insurance with respect to acts or omissions, or alleged acts or omissions, prior to the Effective Time (whether claims, actions or other proceedings relating thereto are commenced, asserted or claimed before or after the Effective Time); provided, however, that, after the Effective Time, Parent and the Surviving Corporation shall not be required to pay annual premiums in excess of 200% of the 2006 annual premium paid by the Company (the amount of which premium is set forth in Schedule 5.8(c) of the Disclosure Letter) (the ‘‘the Company Maximum Premium”), but in such case shall purchase as much coverage as reasonably practicable for such amount. The Company shall have the right, subject to the consent of Parent, which consent shall not be unreasonably withheld, to cause coverage to be extended under the Company’s D&O Insurance policy by obtaining a six-year “tail” policy on terms and conditions no less advantageous than the Company’s existing D&O Insurance, and such “tail” policy shall satisfy the provisions of this Section 5.8 with respect to Indemnified Parties who are or at any time prior to the Effective Time were covered by the Company’s existing D&O Insurance.

(d) The provisions of this Section 5.8 shall survive the consummation of the transactions contemplated hereby and are expressly intended to benefit each of the Indemnified Parties. In the event Parent or the Surviving Corporation or any of their successors or assigns (i) is consolidated with or merges into any other Person and shall not be the continuing or surviving entity in such consolidation or merger and the obligations of Parent or the Surviving Corporation under this Section 5.8 do not become the obligations of the successor under operation of law or (ii) transfers all or substantially all of its assets to any Person, then and in either such case, Parent and the Surviving Corporation shall cause proper provision be made so that the successors and assigns of Parent or the Surviving Corporation shall expressly assume in writing the obligations of Parent and the Surviving Corporation set forth in this Section 5.8 that still survive.

Section 5.9 EMPLOYEE BENEFITS.

(a) Parent hereby agrees to honor, and agrees to cause its Subsidiaries to honor, all employee benefit plans, contracts, agreements and binding commitments of the Company maintained or entered into by the Company prior to the date hereof that apply to any current or former employee or current or former director of the Company or any Subsidiaries of the Company (each, an ‘‘Employee”), including all Company Plans and the employment agreements between the Company and certain of its key employees (copies of which employment agreements have been furnished to Parent); provided, however, that, except as otherwise expressly provided in this Section 5.9, Parent reserves the right to modify or terminate any such plan, contract, agreement or binding commitment in accordance with its terms.

(b) Notwithstanding the provisions of Section 5.9(a):

(i) Parent shall honor all binding commitments of the Company set forth in the ESOP Substitute Excess Deferred Compensation Benefit Plan, the amounts of which commitments are set forth in Schedule 5.9(b)(i) of the Disclosure Letter.

A-25

(ii) Parent agrees that if the Closing has not occurred, the Company may make routine grants of Restricted Stock in December 2006; provided, however, that the terms of such grants of Restricted Stock shall provide that the entire amount of such grants will be forfeited immediately prior to the Effective Time.

(iii) Parent covenants and agrees that for a period of at least one year following the Effective Time, the benefits taken as a whole offered under the Surviving Corporation’s and/or the Parent’s benefit plans, programs, policies and arrangements to Employees will be no less favorable, taken as a whole, to such Employees than the benefits offered under the Company Plans as of the Closing. Without limiting the generality of the foregoing, Employees shall be given credit for years of service with the Company under all applicable plans, programs, policies and arrangements of Parent, there shall be no gaps or lapses of coverage for Employees under group health plans, and Parent shall cause (A) such Employees and their eligible dependents who are participating in the Company group health plan as of the Effective Time to be credited under Parent’s group health plans for the year during which such coverage under such group health plans begins, with any deductibles and copayments already incurred during such year under the group health plans of the Company, and (B) Parent’s group health plan to waive any preexisting condition restrictions to the extent necessary to provide immediate coverage to the extent such preexisting condition restrictions have been waived, or would have been waived, under the Company’s group health plans or as otherwise required by applicable law.

(iv) Parent agrees to implement a severance plan on the terms set forth in Schedule 5.9(b)(iv) of the Disclosure Letter with respect to any Employee whose employment is terminated without cause within one year following the Effective Time.

(v) Parent agrees that (A) bonuses will continue to accrue under the Company’s existing 2006 Management Discretionary Bonus Plan through the Effective Time, shall be allocated to Employees by the Company’s board of directors and senior officers in accordance with such plan, and shall be paid by the Company promptly after the allocation is made, and (B) the Company may establish a bonus pool, which shall be allocated and paid at the Effective Time to Employees as the Company’s board of directors shall determine in its sole discretion, provided, however, that the aggregate amount of bonuses paid under the plans described in clauses (A) and (B) shall not in the aggregate exceed $13,000,000.

(vi) To the extent not made by the Company prior to the Effective Time, Parent shall make (A) the allocations due up to the Effective Time under the Giant Industries, Inc. and Affiliated Companies Deferred Compensation Plan, and set aside corresponding amounts in the grantor trust associated therewith, and (B) any mandatory matching and 3% supplemental contributions due up to the Effective Time under the Giant Industries, Inc. & Affiliated Companies 401(k) Plan, in each case as set forth in Schedule 5.9(b)(vi) of the Disclosure Letter.

(i) Parent shall pay or reimburse the Employees who have employment agreements with the Company as of the date of this Agreement for any excise taxes imposed on compensation payable to them as a result of the Merger as set forth in Schedule 5.9(c)(i) of the Disclosure Letter.

(ii) Parent agrees to continue in effect the retiree medical coverage described in Schedule 5.9(c)(ii) or provide equivalent coverage, subject to the limitations described in Schedule 5.9(c)(ii).

(d) Nothing in this Section 5.9 shall be construed as a contract of employment, and this Section 5.9 shall not give any employee the right to be retained in the employ of Parent or any of its Subsidiaries. Except as provided in Section 5.9(b) and Section 5.9(c), nothing in this Section 5.9 shall be construed to require the provision of coverage or benefits to an Employee except to the extent such coverage or benefits is otherwise required pursuant to applicable law, the terms of the applicable plan or arrangement or any employment agreement or employment offer letter.

(e) Except for the rights conferred pursuant to Section 5.9(c), nothing herein shall be construed to cause the Employees to be third party beneficiaries with respect to the provisions of this Section 5.9 or have any rights to enforce such provisions against the parties.

A-26

Section 5.10 TAX MATTERS.

(a) Each of the Company and its Subsidiaries shall duly and timely file all Tax Returns that it is required to file and shall pay all unpaid Taxes shown on such Tax Returns, subject to timely extensions permitted by law; provided, however, that the Company shall promptly notify Parent of any such extensions.

(b) The Company shall provide Parent with a certification in accordance with the requirements of Treasury Regulation Section 1.1445-2(c)(3) that it is not a United States real property holding corporation.

Section 5.11 RESIGNATIONS. At or prior to the Closing, the Company shall deliver to Parent the written resignations of all members of the board of directors of the Company and all officers of the Company to be effective at the Effective Time.

Section 5.12 409A COMPLIANCE. Parent agrees that prior to the Effective Time, the Company shall be permitted to amend the Company Plans impacted by Code Section 409A to the extent necessary to preserve the intended benefits and avoid adverse tax consequences under Code Section 409A to the participants; provided, however, that no amendment shall be made that could reasonably be expected to result in an increase in cost to, or liability of, the Company except for the time value of money if payment of benefits is required to be accelerated. Parent further agrees that, to the extent that additional amendments may be necessary after the Effective Time to preserve the intended benefits and avoid adverse tax consequences under Code Section 409A to the participants, Parent shall cause such amendments to be made, provided that no such amendment shall be made that could reasonably be expected to result in an increase in cost to, or liability of, the Parent or the Surviving Corporation except for the time value of money if payment of benefits is required to be accelerated.

Section 5.13 DEBT TENDER OFFER. (a) In the event and at such time as requested by Parent (provided that Parent shall coordinate with the Company regarding such timing), the Company shall (i) commence a cash tender offer to purchase all of the Company’s outstanding 11% Senior Subordinated Notes due 2012 (the “11% Notes”) and the Company’s outstanding 8% Senior Subordinated Notes due 2014 (the “8% Notes”, and together with the 11% Notes, the “Senior Subordinated Notes”), or either the 11% Notes or 8% Notes, as requested by Parent, and (ii) solicit the consent of the holders of the Senior Subordinated Notes (or the 8% Notes or 11% Notes, as requested by Parent), regarding the amendments (the “Indenture Amendments”) described on Schedule 5.13 hereto to the covenants contained in the indentures to which the Senior Subordinated Notes (or the 8% Notes or 11% Notes, as applicable) are subject. Any such offer to purchase and consent solicitation (the “Debt Offer”) shall be made on such terms and conditions as are described on Schedule 5.13 and such other terms and conditions agreed to by Parent; provided, that, in any event, the parties agree that the terms and conditions of the Debt Offer shall provide that the closing thereof shall be contingent upon the closing of the Merger. The Company shall waive any of the conditions to the Debt Offer and make any other changes in the terms and conditions of the Debt Offer as may be reasonably requested by Parent, and the Company shall not, without Parent’s prior consent, waive any condition to the Debt Offer described on Schedule 5.13, or make any changes to the terms and conditions of the Debt Offer. The Company covenants and agrees that, subject to the terms and conditions of this Agreement, including but not limited to the terms and conditions to the Debt Offer, it will accept for payment, and pay for, the Senior Subordinated Notes (or the 8% Notes or 11% Notes, as applicable) and effect the Indenture Amendments, in each case contemporaneously with, and contingent upon, the Effective Time. The Company shall enter into a customary dealer manager agreement and a customary information agent agreement with a dealer manager and information agent, respectively, recommended by Parent (and reasonably acceptable to the Company) on terms acceptable to Parent. Parent shall pay directly to the dealer manager and the information agent all compensation owed to them under their respective agreements relating to the Debt Offer, whether or not the Merger is consummated.

(b) Promptly upon the request of Parent, the Company shall prepare, subject to advice and comments of Parent, an offer to purchase the Senior Subordinated Notes (or the 8% Notes or 11% Notes, as applicable) and forms of the related letters of transmittal and summary advertisement, as well as all other information and exhibits that may be necessary or advisable in connection with the Debt Offer (collectively, the “Offer Documents”). In the event that this Agreement is terminated in accordance with Article 7, the Company will have the right to amend the Offer Documents without Parent’s consent. All mailings to the holders of Senior Subordinated Notes in connection with the Debt Offer shall be subject to the prior review, comment and approval of Parent; provided, however, that Parent’s comment and approval shall not be unreasonably withheld or delayed. The Company will use its reasonable best

A-27

efforts to cause the Offer Documents to be mailed to the holders of the Senior Subordinated Notes as promptly as practicable following receipt of the request from Parent under paragraph (a) above to do so.

(c) If at any time prior to the Effective Time any information should be discovered by any party hereto, which should be set forth in an amendment or supplement to the Offer Documents mailed to holders of Senior Subordinated Notes (or the 8% Notes or 11% Notes, as applicable) so that such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto and, to the extent required by applicable law, an appropriate amendment or supplement describing such information shall promptly be prepared by the Company and, if required, filed by the Company with the SEC or disseminated by the Company to the holders of the Senior Subordinated Notes (or the 8% Notes or 11% Notes, as applicable).

(a) The Merger shall not have been consummated by March 31, 2007; provided, however, that the right to terminate this Agreement pursuant to this Section 7.2(a) shall not be available to any party whose failure or whose affiliates’ failure to perform or observe in any material respect any of its obligations under this Agreement in any manner shall have been the principal cause of, or resulted in, the failure of the Merger to occur on or before such date; or

(b) A Governmental Authority shall have issued an order, decree or ruling or taken any other action (including the enactment of any statute, rule, regulation, decree or executive order) permanently restraining, enjoining or otherwise prohibiting the Merger and such order, decree, ruling or other action (including the enactment of any statute, rule, regulation, decree or executive order) shall have become final and non-appealable; provided, however, that the party seeking to terminate this Agreement pursuant to this Section 7.2(b) shall have complied with Section 5.4 and with respect to other matters not covered by Section 5.4 shall have used its reasonable best efforts to remove such injunction, order or decree.

Section 7.3 TERMINATION BY THE COMPANY. At any time prior to the Effective Time, this Agreement may be terminated by the Company, by action of its board of directors, if:

(a) (i) There has been a breach by Parent or Merger Sub of any representation, warranty, covenant or agreement set forth in this Agreement or if any representation or warranty of Parent or Merger Sub shall have become untrue, in either case such that the conditions set forth in Section 6.2 would not be satisfied and (ii) such breach is not curable, or, if curable, is not cured within 30 days after written notice of such breach is given to Parent by the Company; provided, however, that the right to terminate this Agreement pursuant to this Section 7.3(a) shall not be available to the Company if it, at such time, is in material breach of any representation, warranty, covenant or agreement set forth in this Agreement such that the conditions set forth in Section 6.3(a) shall not be satisfied;

(b) At any time prior to obtaining the Requisite Vote, the board of directors of the Company shall have withdrawn the Board’s approval or recommendation of this Agreement and the Merger and recommended and declared advisable a Superior Proposal, or resolved to do the foregoing, after the board of directors shall have

A-29

determined in good faith after consultation with its outside legal counsel that the failure to so withdraw its recommendation and recommend such Superior Proposal would result in a breach of its fiduciary obligations under applicable law; provided, however, that the Company shall not have the right to terminate pursuant to this Section 7.3(b) until it (i) shall have delivered to Parent written notice at least four business days prior to such termination of the Company’s intention to terminate pursuant to this Section 7.3(b), which notice shall state the most recent terms and conditions of the Superior Proposal, the identity of the Person or group making the Superior Proposal, and a copy of the definitive agreement proposed to be entered into in connection with the Superior Proposal; and (ii) shall have provided Parent with a reasonable opportunity to make such adjustments in the terms and conditions of this Agreement and negotiate in good faith with respect thereto during such four-business day period, so that such proposal no longer constitutes a Superior Proposal (which shall be considered by the Company’s board of directors in good faith, after consultation with nationally recognized outside legal counsel, which may be its current outside legal counsel), in which case the Company shall no longer have the right to terminate under this Section 7.3(b) with respect to such proposal; provided that, prior to such termination, the Company shall have paid the fee and reimbursed the expenses required by Section 7.5 by wire transfer in same day funds to an account designated by Parent.

Section 7.4 TERMINATION BY PARENT. At any time prior to the Effective Time, this Agreement may be terminated by Parent, by action of its board of directors, if:

(a) (i) There has been a breach by the Company of any representation, warranty covenant or agreement set forth in this Agreement or if any representation or warranty of the Company shall have become untrue, in either case such that the conditions set forth in Section 6.3(a) would not be satisfied and (ii) such breach is not curable, or, if curable, is not cured within 30 days after written notice of such breach is given by Parent to the Company; provided, however, that the right to terminate this Agreement pursuant to this Section 7.4(a) shall not be available to Parent if it, at such time, is in material breach of any representation, warranty, covenant or agreement set forth in this Agreement such that the conditions set forth in Section 6.2(a) shall not be satisfied; or

(b) The board of directors of the Company shall have withdrawn, modified, withheld or changed, in a manner adverse to Parent, its approval or recommendation of this Agreement or the Merger, or recommended a Superior Proposal, or resolved to do any of the foregoing.

Section 7.5 EFFECT OF TERMINATION.

(a) If this Agreement is terminated:

(i) by the Company pursuant to Section 7.3(b); or

(ii) by Parent pursuant to Section 7.4(b);

then the Company shall pay to Parent the Termination Amount (as defined below) and, in addition, reimburse Parent for all expenses incurred by Parent in connection with this Agreement up to $1,000,000 (the “Maximum Reimbursement Amount”) prior to or upon termination of this Agreement. All payments under this Section 7.5 shall be made in cash by wire transfer to the account designated in Schedule 7.5 of the Disclosure Letter or such other account designated by Parent in writing to the Company prior to the time of such termination. The term “Termination Amount” shall mean $37,500,000. The Company acknowledges that the agreements contained in this Section 7.5 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent would not enter into this Agreement; accordingly, if the Company fails promptly to pay the amounts due pursuant to this Section 7.5, and, in order to obtain such payments, Parent commences a suit which results in a judgment against the Company for the payments set forth in this Section 7.5, the Company shall pay to Parent its costs and expenses (including attorneys’ fees) in connection with such suit, together with interest on the Termination Amount and the Maximum Reimbursement Amount from the date payments were required to be made until the date of such payments at the prime rate of Bank of America, N.A. in effect on the date such payments were required to be made plus one percent (1%). If this Agreement is terminated pursuant to a provision that calls for a payment to be made under this Section 7.5, it shall not be a defense to the Company’s obligation to pay hereunder that this Agreement could have been terminated under a different provision or could have been terminated at an earlier or later time.

A-30

(b) If this Agreement is terminated by the Company or Parent pursuant to Section 7.2(a) and on the date of termination the conditions set forth in Section 6.1(b) have not been satisfied, or if this Agreement is terminated by the Company pursuant to Section 7.3(a), the Escrow Agent shall pay the Deposit to the Company pursuant to the Escrow Agreement as liquidated damages and not as a penalty, and such termination and liquidated damages shall be the Company’s sole remedy in such events. If this Agreement is terminated for any other reason, the Escrow Agent shall pay the Deposit to Parent pursuant to the Escrow Agreement.

(c) In addition to the foregoing, if this Agreement is terminated for any reason other than by Parent pursuant to Section 7.4(a) and the Company has undertaken the Debt Offer at the request of Parent, then Parent shall reimburse the Company within two business days following such termination for its reasonable costs and expenses incurred in connection with the Debt Offer (other than the dealer manager and information agent fees, which Parent agrees to pay directly in all circumstances), up to a maximum of $250,000.

Board of Directors

Giant Industries, Inc.

23733 North Scottsdale Road

Scottsdale, Arizona 85255

Gentlemen:

Deutsche Bank Securities Inc. (“Deutsche Bank”) has acted as financial advisor to Giant Industries, Inc. (the “Company”) in connection with an Agreement and Plan of Merger (the “Merger Agreement”) to be entered into among the Company, Western Refining, Inc. (“Parent”) and New Acquisition Corporation, a wholly owned subsidiary of Parent (“Parent Sub”), which provides, among other things, for the merger of the Company with and into the Parent Sub (the “Merger”). As a result of the Merger, the Company will become a wholly owned subsidiary of Parent and each share of common stock, $0.01 par value per share of the Company (“Company Common Stock”) (other than dissenting shares and shares owned directly or indirectly by the Company or Parent) will be converted into the right to receive $83.00 in cash (the “Merger Consideration”).

You have requested our opinion as to the fairness, from a financial point of view, to the holders of the outstanding shares of Company Common Stock of the Merger Consideration.

In connection with our role as financial advisor to the Company, and in arriving at our opinion, we reviewed certain publicly available financial and other information concerning the Company and Parent, and certain internal analyses, financial forecasts and other information relating to the Company prepared by management of the Company. We have also held discussions with certain senior officers and other representatives of the Company regarding the businesses and prospects of the Company. In addition, Deutsche Bank has (i) reviewed the reported prices and trading activity for the Company Common Stock, (ii) compared certain financial and stock market information for the Company with similar information for certain other companies we considered relevant whose securities are publicly traded, (iii) reviewed the financial terms of certain recent business combinations which we deemed relevant, to the extent publicly available, (iv) reviewed a draft dated August 25, 2006 of the Merger Agreement, and (v) performed such other studies and analyses and considered such other factors as we deemed appropriate.

Deutsche Bank has not assumed responsibility for independent verification of, and has not independently verified, any information, whether publicly available or furnished to it, concerning the Company or Parent, including, without limitation, any financial information, forecasts or projections considered in connection with the rendering of its opinion. Accordingly, for purposes of its opinion, Deutsche Bank has, with your permission, assumed and relied upon the accuracy and completeness of all such information. Deutsche Bank has not conducted a physical inspection of any of the properties or assets, and has not prepared or obtained any independent evaluation or appraisal of any of the assets or liabilities, of the Company or Parent. With respect to the financial forecasts and projections made available to Deutsche Bank and used in its analyses, Deutsche Bank has assumed with your permission that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of the Company as to the matters covered thereby. In rendering its opinion, Deutsche Bank expresses no view as to the reasonableness of such forecasts and projections or the assumptions on which they are based. Deutsche Bank’s opinion is necessarily based upon economic, market and other conditions as in effect on, and the information made available to it as of, the date hereof.

For purposes of rendering its opinion, Deutsche Bank has assumed that the final terms of the Merger Agreement will not differ materially from the terms set forth in the draft we have reviewed. Deutsche Bank has also assumed with your permission that, in all respects material to its analysis, the Merger will be consummated in accordance with the terms of the Merger Agreement, without waiver, modification or amendment of any term, condition or agreement. We have further assumed that all material governmental, regulatory or other approvals and consents required in connection with the consummation of the Merger will be obtained.

B-1

This opinion is addressed to, and is for the use and benefit of, the Board of Directors of the Company, and is not a recommendation to the stockholders of the Company to approve the Merger. This opinion is limited to the fairness, from a financial point of view, of the Merger Consideration, and Deutsche Bank expresses no opinion as to the merits of the underlying decision by the Company to engage in the Merger or as to how any holder of shares of Company Common Stock should vote with respect to the Merger.

Deutsche Bank will be paid a fee for its services as financial advisor to the Company in connection with the Merger, some of which will be payable upon delivery of this opinion and a substantial portion of which is contingent upon consummation of the Merger. The Company has also agreed to reimburse Deutsche Bank for its expenses, and to indemnify Deutsche Bank against certain liabilities, in connection with its engagement. We are an affiliate of Deutsche Bank AG (together with its affiliates, the “DB Group”). One or more members of the DB Group have, from time to time, provided investment banking services to Parent or its affiliates for which it has received compensation, including acting as joint book-running manager in an initial public offering of securities by Parent which closed in January of this year. It is anticipated that some of the indebtedness of the Company will be refinanced in connection with the Merger and that proceeds of the refinancing will be used to discharge certain of that indebtedness which is held by one or more members of the DB Group. DB Group may provide investment and commercial banking services to Parent in the future, for which we would expect DB Group to receive compensation. In the ordinary course of business, members of the DB Group may actively trade in the securities and other instruments and obligations of the Company and Parent for their own accounts and for the accounts of their customers. Accordingly, the DB Group may at any time hold a long or short position in such securities, instruments and obligations.

Based upon and subject to the foregoing, it is Deutsche Bank’s opinion as investment bankers that, as of the date hereof, the Merger Consideration is fair, from a financial point of view, to the holders of the outstanding shares of Company Common Stock.

Very truly yours,

/s/ Deutsche Bank Securities Inc.

Annex C

GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

§ 262. Appraisal rights

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

(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 § 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 § § 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 § 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.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of

C-1

incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(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 § 228 or § 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.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder’s demand for appraisal

C-2

and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

C-3

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
