This Schedule 14D-9 relates to the tender offer by Enzo Acquisition Corp., a Delaware corporation ("Purchaser") and a wholly-owned subsidiary of Pfizer Inc., a Delaware corporation ("Parent" or "Pfizer"), relating to the shares of Common Stock and as disclosed in a Tender Offer Statement on Schedule TO (the "Schedule TO") filed by Purchaser and Parent with the Securities and Exchange Commission (the "SEC") on January 6, 2004. As described in the Schedule TO, Purchaser has offered to purchase all of the outstanding shares of Common Stock at a price of $35.00 per share, net to the selling stockholders in cash (the "Offer Price"), upon the terms and subject to the conditions set forth in Purchaser's Offer to Purchase dated January 6, 2004 (the "Offer to Purchase") and in the related Letter of Transmittal (the "Letter of Transmittal" which, together with the Offer to Purchase, as they may be amended and supplemented from time to time, constitute the "Offer"). Copies of the Offer to Purchase and related Letter of Transmittal are filed as Exhibits (a)(1)(A) and (a)(1)(B), respectively, to the Schedule TO and are incorporated herein by reference. As set forth in the Schedule TO, Purchaser's and Parent's principal executive offices are both located at Pfizer Inc., 235 East 42nd Street, New York, New York 10017. The Offer is being made pursuant to an Agreement and Plan of Merger, dated as of December 19, 2003 (as such agreement may be amended and supplemented from time to time, the "Merger Agreement"), by and among Parent, Purchaser and the Company. The Merger Agreement provides, among other things, for (1) the making of the Offer and (2) the merger of Purchaser with and into the Company as soon as practicable after the satisfaction or waiver of the conditions set forth in the Merger Agreement (the "Merger"). Following consummation of the Merger, the Company will continue as the surviving corporation (the "Surviving Corporation") and as a wholly owned subsidiary of Parent.

The Merger Agreement is more fully described in Item 3 of 2 this Schedule 14D-9. A copy of the Merger Agreement has been filed as Exhibit 99.2 to the Form 8-K filed by the Company on December 23, 2003, and is incorporated herein by reference. ITEM 3. PAST CONTACTS, TRANSACTIONS, NEGOTIATIONS AND AGREEMENTS. Except as described in this statement (including the Exhibits and Annex A hereto, the "Information Statement"), there are no material agreements, arrangements or understandings or any actual or potential conflicts of interest between the Company or its affiliates and (a) the Company's executive officers, directors or affiliates or (b) Parent or any of its executive officers, directors or affiliates. (A) ARRANGEMENTS WITH EXECUTIVE OFFICERS AND DIRECTORS OF THE COMPANY. Certain material agreements, arrangements or understandings between the Company or its affiliates and certain of its directors and executive officers are described in the Information Statement pursuant to Rule 14f-1 under the Securities Exchange Act of 1934, as amended. The Information Statement is attached hereto as Annex A and is incorporated herein by reference. Certain of the members of the Company's management and board of directors (the "Board") have financial interests in the Merger that are in addition to their interests as stockholders of the Company. The Board was aware of these interests and considered them, among other matters, in approving the Merger Agreement. Existing Employment Agreements with the Company. In addition to the existing letter agreements with Drs. Newton, Krause and Dasseux, and Messrs. Mayleben and Frank E. Thomas, described in Annex A hereto, the Company is also a party to letter agreements with Dr. Adeoye Y. Olukotun, Senior Vice President, Clinical and Regulatory Affairs and Chief Medical Officer of the Company, and William F. Brinkerhoff, Vice President, Business Development of the Company, dated as of June 4, 2003 and April 19, 2002, respectively, which each specify an initial base salary amount and the right to receive an annual bonus in an amount up to 25% of base salary or 20% of base salary, respectively, based on specific achievement of performance milestones. The employment relationship of each of these officers with the Company is that of employment at will. If the Company terminates the employment of any of these officers without cause, the terminated officer will receive his salary and benefits for six months after termination of employment. In connection with these letter agreements, the officers entered into non-competition and confidentiality agreements with the Company. Stock Options and Employee Stock Purchase Plan. Under the terms of the Merger Agreement and the Company's stock option plans, each option outstanding pursuant to the Company's employee stock option plan will be treated as described below. At the effective time of the Merger, each outstanding vested option will be surrendered and cancelled and only entitle the holder to receive an amount in cash from the Surviving Corporation equal to the product of (i) the total number of shares of Common Stock subject to the vested option and (ii) the excess, if any, of the per share cash consideration paid in the Merger over the per share exercise price of the vested option. At the effective time of the Merger, except as described below with respect to non-employee directors, each outstanding unvested option will be surrendered and cancelled and the holder of the cancelled unvested option will be entitled to receive the following amounts from the Surviving Corporation: (A) Immediately following the Merger, the holder will receive 50% of the option value, calculated, with respect to each unvested option, as the product of (i) the total number of shares of Common Stock subject to the unvested options and (ii) the excess, if any, of the per share cash consideration paid in the Merger over the per share exercise price of such unvested option. (B) Except with respect to certain officers of the Company, as discussed below, the remainder of the option value of cancelled unvested options will be paid with interest on each date following the effective date of the Merger on which the option would have vested had it not been cancelled, provided the holder continues to be an employee of the Surviving Corporation, Parent or any of their affiliates on such vesting date. 3 (C) With respect to the cancelled unvested options of the executive officers of the Company and four other Company officers, the remainder of the option value of the cancelled unvested options will be paid with interest on the third anniversary of the effective date of the Merger, provided the holder continues to be an employee of the Surviving Corporation, Parent or any of their affiliates on that date. If the employment with the Surviving Corporation, Parent or any of their affiliates of any holder of a cancelled unvested option is terminated by the Surviving Corporation, Parent or any of their affiliates without cause, or if the holder's employment is terminated by the holder with good reason, or due to the holder's death or disability, the Surviving Corporation will immediately pay to the holder the balance of the unpaid value of the cancelled unvested option with interest. The right to payment of the balance of the unpaid value of the cancelled unvested options will be forfeited if the holder's employment is terminated for cause by the Surviving Corporation, the Parent or any of their affiliates, or without good reason by the holder. If an option holder's employment with the Company is terminated by the Company other than for cause, or by the holder with good reason, on or after the date of the consummation of the Offer and before the effective time of the Merger, the holder's options (vested and unvested) will not terminate in connection with such termination of employment and will be treated as outstanding immediately before the effective date of the Merger. At the consummation of the Offer, all options held by non-employee members of the Board will become fully vested, and at the effective time of the Merger each such unexercised option will be surrendered and cancelled and entitle the holder to receive an amount in cash from the Surviving Corporation equal to the sum of the products of (i) the total number of shares of Common Stock subject to each of the options and (ii) the excess, if any, of the per share cash consideration paid in the Merger over the per share exercise price of such options. Employee Stock Purchase Plan. The Company's employee stock purchase plan will be terminated effective January 1, 2004, subject to consummation of the Offer. Accelerated Performance Bonuses. The Company has accelerated the payment to certain eligible employees of the annual cash performance bonuses that were granted in respect of 2003, and normally would be paid in the first quarter of 2004, by causing such bonuses to be paid in 2003 in an aggregate amount that, under the Merger Agreement, may not exceed $1,050,000. Section 16 Matters. Prior to the effective time of the Merger, the Company will take all such steps as may be required to cause any dispositions of Company Common Stock or options resulting from the Merger by each officer and director who is subject to the reporting requirements of Section 16(a) of the Exchange Act, to be exempt from liability under Rule 16b-3 under the Exchange Act. Indemnification and Insurance. Under the Merger Agreement, Parent has agreed that the Certificate of Incorporation and Bylaws of the Surviving Corporation will, with respect to indemnification of officers, directors, employees and agents, not be amended or repealed for a period of six years after the completion of the Merger in any manner that would adversely affect the rights of the persons who were indemnified prior to completion of the Merger, unless such amendment is required by law. Parent and the Surviving Corporation shall jointly and severally indemnify, defend and hold harmless, the present and former officers, directors and employees of the Company or any of its subsidiaries, in their capacities as such, in accordance with the Certificate of Incorporation and Bylaws, or other charter documents, of the Company and its subsidiaries and any agreements or contracts maintained by the Company and its subsidiaries, to the fullest extent permitted by the terms thereof against all losses, expenses, claims, damages and liabilities arising out of or pertaining to the Offer or the Merger or otherwise with respect to acts or omissions occurring on or prior to completion of the Merger. For six years after completion of the Merger, Parent will cause the Surviving Corporation to maintain officers' and directors' liability insurance in respect of matters occurring at or prior to completion of the Merger covering each such person covered immediately prior to completion of the Merger by the Company's officers' and directors' liability insurance policy with as least the same coverage containing terms and conditions that are not materially less favorable to those of such policy in effect on the date of the Merger Agreement, provided that in satisfying its obligation with respect to the maintenance of insurance, Parent will 4 not be obligated to cause the Surviving Corporation to pay premiums in excess of 150% of the current amount per annum paid by the Company. (B) AGREEMENTS WITH PARENT. The Confidentiality Agreement. On June 25, 2002, the Company and Parent entered into a confidentiality agreement in connection with their mutual consideration of a possible transaction between the Company or its subsidiaries, affiliates or joint ventures and Parent or its subsidiaries, affiliates or joint ventures. The summary of that agreement and amendments thereto dated September 5, 2003, September 6, 2003, and December 2, 2003, contained in the Section titled "Purpose of the Offer and the Merger; Plans for Esperion; The Merger Agreement; Confidentiality Agreement" of the Offer to Purchase, dated January 6, 2004, which is filed as Exhibit (a)(1)(A) to the Schedule TO and which is being mailed to stockholders together with this Schedule 14D-9, is incorporated herein by reference. The Merger Agreement. The summary of the Merger Agreement and the statement of the conditions of the Offer contained in the Sections titled "Terms of the Offer" and "Certain Conditions to the Offer," respectively, of the Offer to Purchase, dated January 6, 2004, which is filed as Exhibit (a)(1)(A) to the Schedule TO and which is being mailed to stockholders together with this Statement, are incorporated herein by reference. The summary and description of the Merger Agreement is qualified in its entirety by reference to the Merger Agreement, which has been filed as Exhibit 99.2 to the Form 8-K filed by the Company on December 23, 2003 and is incorporated herein by reference. In connection with the negotiation of the Merger Agreement, the Company amended the Rights Agreement dated as of April 18, 2002, as previously amended on November 26, 2002 and July 29, 2003, by and between the Company and StockTrans, Inc., as rights agent (the "Rights Agreement"), to render it inapplicable to the transactions contemplated by the Merger Agreement. The Collaboration and License Agreement. In connection with the execution of the Merger Agreement, the Company executed an amendment to the Collaboration and License Agreement, dated June 24, 1998 (the "Pharmacia Agreement"), between the Company and Pharmacia AB ("Pharmacia"), which is now a subsidiary of Parent. Under the terms of the original Pharmacia Agreement, among other things, the Company acquired from Pharmacia exclusive worldwide rights to certain technology used to develop the Company's ETC-216 ("AIM") product candidate, including for certain fees and milestone payments, and Pharmacia has the right to co-develop and exclusively market AIM outside the United States and Canada once the Company completes Phase IIb clinical trials and the right of first negotiation if the Company wishes to pursue a co-development and co-promotion arrangement in the United States and Canada with respect to the AIM product candidate. The amendment to the Pharmacia Agreement provides that if the Merger Agreement terminates and a termination fee is payable by the Company to Parent, Pharmacia will thereafter have the right to elect to license from the Company the exclusive right to develop, manufacture and market everywhere in the world pharmaceutical products that include AIM as their active ingredient. If Pharmacia exercises this right, it would be required to pay $100,000,000 to the Company at the time the election is made and an additional $100,000,000 in the event that the FDA issues a final approval for a licensed product. Additionally, Pharmacia would be obligated to pay to the Company a 15% annual royalty on net sales of the licensed products in the United States and Canada, in addition to the royalties payable under the original agreement for net sales elsewhere in the world. Pharmacia would also assume all development and manufacturing costs. This summary of the Agreement and the amendment thereto is qualified in its entirety by reference to the full text of the agreement and amendment, which have been filed as Exhibits (e)(2) and (e)(3), respectively, to this Schedule 14D-9 and are incorporated herein by reference. 5 ITEM 4. THE SOLICITATION OR RECOMMENDATION. BACKGROUND OF THE TRANSACTION In June 1998, the Company entered into the original Pharmacia Agreement described above. Since 1998, the Company's management periodically explored and assessed, and discussed with the Board, strategic alternatives for the Company, including, among other things, strategies to grow the Company's business and operations through co-development/co-promotion partnerships and licensing agreements with large pharmaceutical companies, including Pfizer. In mid-March 2002, at the American College of Cardiology Meetings in Atlanta, GA, Esperion's chief executive officer spoke with Pfizer's former clinical vice president for marketed cardiovascular products about a potential partnering opportunity. At about the same time, Pfizer received and reviewed a non-confidential data package from Esperion. In mid-to-late June 2002, the Company's vice president for business development contacted Pfizer about Esperion's interest in exploring partnerships relating to the development and commercialization of its leading product candidates. On June 25, 2002, the Company entered into the confidentiality agreement with Pfizer, referred to above, which related to the disclosure by the Company to Pfizer of certain proprietary information relating to ETC-642 and ETC-588 in order to explore a potential co-development/co-promotion collaboration with Pfizer with respect to these product candidates. Also on June 25, 2002, the Company held a meeting with Pharmacia to discuss AIM and other Esperion product candidate development programs and to explore a potential co-development/co-promotion collaboration with Pharmacia with respect to these product candidates. On July 31, 2002, Pharmacia and Pfizer entered into a merger agreement whereby Pharmacia subsequently became a wholly-owned subsidiary of Pfizer. On August 28, 2002, the Company held a scientific meeting with Pfizer in New London, Connecticut to discuss the ETC-642 and ETC-588 development programs. During the second half of 2002, senior management of Esperion initiated a more formalized process to speak with various large pharmaceutical companies potentially interested in pursuing a strategic partnership relating to one or more of Esperion's four major compounds, AIM, ETC-588, ETC-642, and ETC-1001. Thereafter, Esperion had preliminary discussions with many of the major domestic and foreign pharmaceutical organizations, including Pfizer, to assess opportunities of mutual interest. The Company's chief executive officer and its chief operating officer/chief financial officer (the "chief operating officer") regularly reviewed with the Board the status of these discussions and Esperion's strategic plans for ensuring the long-term success of Esperion and plans for maximizing stockholder value. On April 16, 2003, Pfizer completed its merger with Pharmacia. A representative of Pfizer contacted Esperion's vice president for business development and indicated that Pfizer would like to discuss ETC-216 with Esperion. As a result of this merger, Pfizer indirectly succeeded to Pharmacia's rights to AIM under the Pharmacia Agreement. Esperion entered into amendments to the confidentiality agreement then in effect with Pfizer on September 5, 2003 and September 6, 2003, in order to include AIM within the scope of the product candidates that Pfizer would want to consider as part of a co-development/co-promotion or other agreement. On September 8, 2003, the Company held a scientific meeting with Pfizer to discuss the AIM, ETC-642 and ETC-588 development programs. This was followed by a technical due diligence meeting at Esperion's offices for these programs on October 13 and 14, 2003 and a commercial assessment meeting in New York City on October 27, 2003. The Company provided a term sheet proposal for collaboration on these programs to Pfizer on November 3, 2003. Pfizer conducted due diligence efforts relating to these product candidates in November and December 2003. 6 In early November 2003, one of the major pharmaceutical companies with which the Company was discussing a possible partnership agreement advised the Company that it was interested in discussing a possible acquisition of the Company. Later in November 2003, another entity expressed a similar interest in discussing a possible acquisition of the Company. On November 14, 2003, the Board determined to engage Lehman Brothers Inc. ("Lehman Brothers") to act as its financial advisor in connection with a possible sale of the Company. On November 10, 2003, the Company requested Pfizer to respond to the November 3 product collaboration term sheet. On November 13, 2003, Pfizer's vice president of licensing called representatives of Esperion to communicate Pfizer's interest in a broad co-development/co-promotion collaboration on AIM, ETC-588 and ETC-642. On November 19, 2003, representatives of Pfizer contacted Esperion's chief executive officer regarding the possibility of exploring strategic relationships with Esperion, including a potential acquisition. Thereafter, until mid-December 2003, Lehman Brothers, after consultation with senior management of the Company, contacted a number of major pharmaceutical companies, including Pfizer, to determine whether they might have an interest in acquiring Esperion. On November 24, 2003, Esperion management discussed by telephone conference call the Pfizer inquiry with the Board, representatives of Lehman Brothers and Esperion's outside legal counsel, Morgan, Lewis & Bockius LLP ("Morgan Lewis"). On November 24, 2003, representatives of Pfizer contacted the Company's chief executive officer and chief operating officer to express an initial interest in the acquisition of Esperion by Pfizer at a price range of between $30 to $35 per share of Common Stock. Thereafter, the Board met by telephone conference call and discussed Pfizer's initial expression of interest with Lehman Brothers, Morgan Lewis and members of management. In addition, the Board, Morgan Lewis and members of management discussed the fiduciary duties of the Board in light of this initial expression of interest by Pfizer. The Board also instructed management to continue to pursue other partnering and licensing agreements that the Company was then actively negotiating. On November 25, 2003, Pfizer delivered a due diligence request list to Esperion requesting certain confidential information of the Company that Pfizer would need to review in order to make a determination as to whether it was willing to engage in further discussions regarding a potential acquisition of the Company. On November 26, 2003, the Board met by telephone conference call and discussed developments regarding Pfizer and the possible sale of the Company with representatives of Lehman Brothers and Morgan Lewis and members of the Company's management. On November 28, 2003, after discussing such agreements for more than a year, the Company's Compensation Committee approved the final terms of change of control agreements with management (the "Change of Control Agreements") that would provide, among other things, that, in the event the management member were to be terminated without cause or to resign with good reason within two years after a change of control of the Company, all of the unvested options then held by such management member would accelerate and become immediately exercisable and such management member would be entitled to receive a severance payment equal to 100% (150% in the cases of the chief executive officer and the chief operating officer) of the then current annual compensation receivable by such management member. On November 29, 2003, the Board received a memorandum prepared by Morgan Lewis outlining the Board's fiduciary duties in situations where third parties express interest in a potential acquisition of the Company. 7 On December 2, 2003, the Board met by telephone conference call with representatives of Lehman Brothers, Morgan Lewis and management being present. At this meeting, the status of contacts and discussions with a number of different companies, including Pfizer, was discussed. The Board instructed management to provide Pfizer with an initial response to Pfizer's due diligence request list and to continue to negotiate the partnering and licensing agreements that the Company was then negotiating and also to continue to explore the possible sale of the Company to other parties. Also on December 2, 2003, the Company provided Pfizer with a proposed amendment to the confidentiality agreement then in effect in order to provide Pfizer with access to additional non-public information about the Company. Between December 3, 2003 and December 5, 2003, the Company and another party negotiated the terms of an amendment to that other party's confidentiality agreement with the Company to enable that party to conduct due diligence to determine whether it might want to acquire the Company. On December 4, 2003, Pfizer and the Company finalized their negotiations of the amendment to the confidentiality agreement and executed the amendment. Following the execution of the amendment, Pfizer was granted access to additional non-public information about the Company. On December 5, 2003, the other potential acquiror and the Company executed the amendment to that company's confidentiality agreement and contemporaneously the other potential acquiror was granted access to the same confidential information of the Company that was provided to Pfizer. Although this potential acquiror conducted such corporate and product candidate due diligence and two other companies met with the Company's management to discuss the Company's product candidates, except for the agreement discussed herein with Pfizer, neither Lehman Brothers nor management of the Company have received any written offers from any third parties regarding a potential acquisition of Esperion. Also on December 5, 2003, a representative of Pfizer contacted the Company's chief executive officer to discuss the potential acquisition of Esperion and committed to providing the Company with a price per share for the Company's Common Stock by December 10, 2003. On December 9, 2003, Esperion formally executed an agreement retaining Lehman Brothers as the Company's financial advisor in connection with a potential sale of the Company. During the morning of December 10, 2003, the other potential acquiror contacted the Company's chief executive officer and chief operating officer to say it would not seek to proceed with an acquisition of Esperion. During the evening of December 11, 2003, representatives of Lazard Freres & Co. LLC ("Lazard"), Pfizer's financial advisor, contacted representatives of Lehman Brothers to discuss a potential acquisition of Esperion by Pfizer at a price of $35 per share, subject to approval by Pfizer's board, satisfactory completion of due diligence and negotiation of the terms and conditions of a mutually acceptable merger agreement. On December 12, 2003, representatives of Pfizer contacted the Company's chief executive officer and chief operating officer to reiterate the discussion between the companies' financial advisors. The companies' representatives also discussed an agenda and timeline for further discussions. On December 12, 2003, the Board and representatives of management, Morgan Lewis and Lehman Brothers met by telephone conference call to discuss the status of discussions with Pfizer, the termination of discussions with the other potential acquiror and the status of negotiations with other parties on proposed strategic collaborations, partnering and licensing agreements. At the conclusion of the meeting, the Board instructed management to continue discussions with Pfizer, but also to continue strategic collaboration, partnering and license agreement negotiations. The Board also determined to seek a higher price from Pfizer. On December 13, 2003, Morgan Lewis distributed a draft merger agreement to representatives of Pfizer's outside counsel, Cadwalader Wickersham & Taft LLP ("Cadwalader"). On December 15, 2003, the Company's chief executive officer, chief operating officer and the lead independent outside director on the Board attended meetings in New York City with representatives of Pfizer, including, among others, its chief executive officer and chief financial officer, for the purpose of discussing the 8 potential acquisition of Esperion by Pfizer. During these meetings, Pfizer informed the Company's representatives that it would consider a variety of partnering alternatives, including an acquisition of 100% of the shares of Common Stock. On the night of December 15, 2003, after careful consideration of the timing and quality of the negotiations on partnering and licensing agreements with other parties, representatives of the Company contacted representatives of Pfizer to advise them that, due to timing constraints, Pfizer's only option for a strategic transaction with Esperion would be an acquisition of 100% of the shares of Common Stock. The representatives of Pfizer indicated that they would discuss a potential acquisition of Esperion the following morning. On the morning of December 16, 2003, the Board, management and representatives of Morgan Lewis and Lehman Brothers met by telephone conference call to discuss the status of negotiations with Pfizer. During this teleconference, the Company's chief executive officer received a telephone call from Pfizer's chief executive officer, who indicated that he would recommend to the Pfizer board the acquisition of Esperion. The Board approved further negotiations with Pfizer, and reiterated its views that the price per share of Common Stock should be $35 or more and that a definitive agreement must be entered into no later than December 19, 2003, due to timing constraints associated with partnering and licensing agreements that the Company was still actively negotiating. On December 17, 2003, Cadwalader delivered to Morgan Lewis Pfizer's comments on the Morgan Lewis draft of the merger agreement. In addition, on December 17, 2003, Cadwalader delivered an initial draft of an amendment to the Pharmacia Agreement to representatives of Esperion and Morgan Lewis. Also on December 17, 2003, the Board, management and representatives of Morgan Lewis and Lehman Brothers met by telephone conference call to discuss the status of negotiations with Pfizer. The Board instructed management to continue pursuing the negotiations with Pfizer and to seek a price higher than $35 per share of Common Stock, while simultaneously continuing to negotiate the partnering and licensing agreements the Company was then still actively negotiating. The Board also appointed a strategy committee of the Board to consider price and other issues with Pfizer. On the same day, December 17, 2003, representatives of Cadwalader and Morgan Lewis met to discuss and negotiate the terms of the merger agreement while representatives of Cadwalader and Pfizer continued to perform due diligence. Also on December 17, 2003, representatives of Lehman Brothers discussed by telephone certain terms of the merger agreement with Lazard. At this meeting, Lehman Brothers reiterated the Company's interest in an acquisition price per share of Common Stock higher than $35. On December 17, 2003, the Company's chief executive officer and chief operating officer met with representatives of Pfizer to discuss other merger-related issues. On December 18, 2003, the Corporate Strategy Committee appointed by the Board met by telephone conference call with representatives of management, Lehman Brothers and Morgan Lewis and reviewed the status of negotiations with Pfizer. Later in the evening on December 18, 2003, representatives of the Company, as well as representatives of Morgan Lewis and Lehman Brothers, met with representatives of Pfizer, as well as representatives of Cadwalader and Lazard, to negotiate the open business issues in the merger agreement. At this meeting, the companies agreed that they would proceed with the transaction only if: - the acquisition were structured as a cash tender offer for all of the Common Stock at a price per share of $35, - the Pharmacia Agreement relating to AIM was amended on mutually agreeable terms to provide for an exclusive license to Pfizer to manufacture and commercialize AIM in the event that the merger agreement terminated and the Company was obligated to pay a termination fee to Pfizer, and 9 - mutually agreeable terms could be reached as to treatment of outstanding employee options to purchase shares of Common Stock. Representatives of the Company, together with representatives of Morgan Lewis and Lehman Brothers, held various teleconferences with the Company's chief executive officer to discuss the terms of the Pfizer offer, and the Company's representatives continued to negotiate the key terms of the merger agreement with Pfizer throughout the evening. In addition, the parties discussed the need for the Company to rescind the Change of Control Agreements executed by management to facilitate the structuring of the potential acquisition as a tender offer. On December 19, 2003, the final terms of the Pfizer offer were agreed, subject to completion of the merger agreement and the amendment to the Pharmacia Agreement and approval of the Board. During the afternoon on December 19, 2003, a meeting of the Board was held, at which all of the directors of the Company were present by telephone conference call, as well as representatives of Lehman Brothers and Morgan Lewis. At the meeting, Morgan Lewis discussed with the Board the material terms of the merger agreement and the related transactions. Representatives from Morgan Lewis also reviewed with the Board its fiduciary duties in the context of the transaction. Representatives of the Company provided the Board with a summary of the history of the transaction, including a discussion regarding the process undertaken in negotiating the merger agreement with Pfizer. The Company's chief operating officer also reviewed with the Board the proposed economic and other terms of the proposed amendment to the Pharmacia Agreement. Lehman Brothers then reviewed with the Board a detailed analysis of the financial terms of the proposed transaction and provided an oral opinion, which was subsequently confirmed by receipt of a written opinion dated the same date that, as of such date and based upon and subject to certain considerations and assumptions stated therein, the consideration to be offered to Esperion stockholders in connection with Pfizer's tender offer was fair to such stockholders from a financial point of view. Following further discussion, the Board unanimously approved the merger agreement and the related matters, and voted to recommend Pfizer's tender offer to the Company's stockholders. The Board also authorized its Compensation Committee to approve the final treatment of outstanding stock options and authorized the officers of the Company to execute the definitive merger agreement and the related transaction documents and obtain the necessary revocations of the Change of Control Agreements. Subsequent to the full Board meeting, the Compensation Committee of the Board met separately by conference telephone conference call with representatives of Morgan Lewis being present and approved the treatment of outstanding stock options set forth in the merger agreement. Also on December 19, 2003, the revocations of the Change of Control Agreements were made effective. Following the meeting of the Board and the meeting of the Compensation Committee, the Company and Pfizer and its subsidiary executed the Merger Agreement as of December 19, 2003. On December 21, 2003, Esperion and Pfizer issued a joint press release announcing the execution of the Merger Agreement. REASONS FOR THE OFFER AND THE MERGER At a meeting held on December 19, 2003, the Board took the following unanimous actions: - Determined that the Merger Agreement, the Offer, the Merger and the other transactions contemplated by the Merger Agreement, including the amendment to the Pharmacia Agreement are fair to and in the best interests of the Company and its stockholders; - Approved and declared advisable the Merger Agreement, the Offer, Merger and the other transactions contemplated by the Merger Agreement, including the amendment to the Pharmacia Agreement; and - Determined to recommend that the Company's stockholders accept the Offer and tender their shares of Common Stock in the Offer and, if necessary under applicable law, following the Offer approve and adopt the Merger Agreement. 10 BASIS FOR BOARD ACTION In approving the Merger Agreement and the transactions contemplated thereby, and recommending that the Company's stockholders accept the Offer and tender their shares of Common Stock pursuant to the terms of the Offer, and, if necessary under applicable law, following the Offer approve and adopt the Merger Agreement and the Merger, the Board considered a number of factors that support its approval and recommendation, including: Market Premium. The Board considered the historical market prices and recent trading activity and trading range of the shares of Common Stock, including the fact that the Offer Price represented (a) a premium of approximately 55% over the $22.57 closing price of the shares of Common Stock on the Nasdaq National Market on December 18, 2003, the last full trading day prior to the meeting of the Board to approve the Merger Agreement, and (b) a premium of approximately 54% over the average closing price of the shares of Common Stock on the Nasdaq National Market for the preceding 20 trading days. The Board also recognized, however, as discussed below, the possibility that the market price did not fully reflect the appropriate value of the Company because of the 9,726,900 shares of Common Stock beneficially owned by Scott Sacane, Durus Capital Management, LLC, Durus Capital Management (N.A.), LLC (together, the ("Sacane Group"), Durus Life Sciences Master Fund, Ltd. (the "Master Fund"), and Artal Long Biotech Portfolio, and the expected recovery of the short-swing profits resulting from certain transactions made by the Master Fund that are subject to Section 16(b) of the Securities Exchange Act of 1934, as amended. Strategic Alternatives. The Board considered all of the risks that the Company's stockholders would continue to face unless the Company agreed to be acquired for cash by a company interested in assuming those risks. These risks include the need for the Company to finance its research and development activities and the commercialization of any products approved by the FDA through licensing and other agreements because the Company is a development stage company with a history of losses and the inability to independently conduct clinical trials and obtain regulatory approvals for its product candidates; the risk that the Company's product candidates will never be successfully developed and commercialized because they are based on unproven technology and therapeutic approvals that have never been widely tested or approved for marketing, that is, the treatment of cardiovascular disease based upon the beneficial properties of high density lipoprotein to remove excess cholesterol and other lipids from artery walls and other tissues ("HDL Therapies"), and the other risks that the Company has disclosed in its annual report on Form 10-K for its 2002 fiscal year and its July 2003 registration statement. The Board also considered the process, undertaken in response to an unsolicited indication of interest to acquire the Company, to solicit third party indications of interest in an acquisition of the Company while it continued to explore collaboration and licensing agreements, and the fact that no other party presented the Company with a definitive proposal to acquire all of the outstanding shares of Common Stock. Lehman Brothers' Fairness Opinion. The Board considered the opinion of Lehman Brothers delivered to the Board on December 19, 2003 that, as of that date, based upon and subject to certain considerations and assumptions stated in its written opinion, the consideration to be offered to holders of shares of Common Stock pursuant to the Merger Agreement was fair from a financial point of view to such holders. A copy of the written opinion rendered by Lehman Brothers to the Board, setting forth the procedures followed, the matters considered, the assumptions made and limitations on the review undertaken by Lehman Brothers in arriving at its opinion, is attached hereto as Annex B and incorporated herein by reference. Stockholders are urged to read this opinion in its entirety. The opinion of Lehman Brothers was presented for the benefit of the Board in connection with its consideration of the Merger Agreement and is directed only to the fairness of the consideration to be offered to the holders of shares of Common Stock pursuant to the Offer and the Merger. The opinion does not constitute a recommendation to any stockholder as to whether such stockholder should tender any shares of Common Stock pursuant to the Offer or how such stockholder should vote on the proposed Merger or any matter related thereto. The Board was aware that Lehman Brothers became entitled to certain fees upon the delivery of its fairness opinion and certain fees contingent upon consummation of the Offer. See Item 5 -- "Persons/Assets Retained, Employed, Compensated or Used." 11 Management's Recommendation. The Board considered the presentations by, and discussions with, management of the Company and representatives of the Company's financial and outside legal advisors regarding the Offer and the Merger. Terms of the Merger Agreement. The Board considered the fact that the terms of the Merger Agreement were determined through arm's-length negotiations between the Company and its outside legal and financial advisors, on the one hand, and Parent and its legal and financial advisors, on the other. Among other provisions of the Merger Agreement considered important by the Board were: - the "fiduciary out" provisions of the Merger Agreement, which permit another qualified person to make a superior offer and the Board to respond to such an offer and, in certain circumstances, to terminate the Merger Agreement; - the fact that the Merger Agreement provides for a prompt tender offer that consists of cash for all of the Company's shares of Common Stock to be followed by a second step merger for the same cash consideration, thereby enabling the Company's stockholders to obtain the benefits of the transaction at the earliest possible time; and - the absence of any financing condition and the fact that Parent has available to it sufficient funds to consummate the Offer and the other transactions contemplated by the Merger Agreement. Likelihood of Success. The Board considered the likelihood of satisfaction of all conditions to consummation of the Offer and the likelihood of receipt of required regulatory approvals. OTHER CONSIDERATIONS The Board also considered certain negative factors, including the following: Loss of Future Profits. Since the stockholders of the Company will not receive stock of the Parent in the transaction, the Company's stockholders will lose the opportunity to participate in the potential success of the Company's HDL Therapies and in any future growth and profits of the Company. In addition, the Company's stockholders will not benefit from the expected synergies between the Company and Parent. Unlikelihood of a Superior Offer. The $40 million termination fee required by the terms of the Merger Agreement to be paid by the Company in certain circumstances would make it more costly for another potential purchaser to acquire the Company. In addition, the amendment to the Pharmacia Agreement with Parent's subsidiary, Pharmacia, which grants Pharmacia increased rights to AIM in the event the Merger Agreement is terminated and a termination fee is payable by the Company, may make the Company less attractive as an acquisition candidate to another potential purchaser. Possible Lower Premium. The market price of the shares of Common Stock may not fully reflect the appropriate value of the Company because of the market overhang represented by the 9,726,900 shares of Common Stock beneficially owned by the Master Fund and the Sacane Group. In addition, the historical market price of the shares of Common Stock may have been adversely affected by uncertainty as to whether the Company would be successful in resolving its litigation against the Master Fund and the Sacane Group relating to its recovery of short swing profits under Section 16(b) of the Securities Exchange Act of 1934, as amended, and as to the amount of such recovery. The Company has been discussing a settlement with the Master Fund and the Sacane Group, which would provide for, among other things, the Master Fund's agreement to pay the Company approximately $32 million of short-swing profits and the dismissal by the court of the Company's complaint filed against the Master Fund and the Sacane Group. Therefore, the Offer Price may represent a lower premium over the real value of the outstanding shares of Common Stock. The foregoing includes the material factors considered by the Board. In view of its many considerations, the Board did not find it practical to, and did not, quantify or otherwise assign relative weights to the various individual factors considered. In addition, individual members of the Board may have given different weight to the various factors considered. The Board was also aware of and considered the fact that certain members of management and the Board had interests in the Merger that were in addition to their interests as stockholders of the Company. See Item 3 -- "Past Contacts, Transactions, Negotiations and Agreements, Arrangements 12 with Executive Officers and Directors of the Company." After weighing all of these considerations, the Board unanimously determined to approve the Merger Agreement and the related matters and recommend that holders of shares of Common Stock tender their shares in the Offer and, if necessary under applicable law, following the Offer approve and adopt the Merger Agreement. INTENT TO TENDER. After reasonable inquiry and to the Company's knowledge, each executive officer and director of the Company currently intends to tender all outstanding shares of Common Stock held of record or beneficially owned by such person to Purchaser in the Offer. ITEM 5. PERSON/ASSETS, RETAINED, EMPLOYED, COMPENSATED OR USED. The Company retained Lehman Brothers to provide financial advisory services in connection with the Offer and the Merger. Such services include the rendering of an opinion as to the fairness from a financial point of view of the stockholders of the Company of the consideration to be received in the Offer and the Merger. Pursuant to the terms of Lehman Brothers' engagement, the Company agreed to pay Lehman Brothers for its financial advisory services (i) a retainer of $150,000 that was paid upon the signing of the engagement agreement, (ii) a fee of 0.70% of the consideration payable upon a transaction occurring where control of 20% or more of the outstanding shares of Common Stock is transferred for consideration, and (iii) a fee of 10% of the estimated fee referred to in clause (ii) above upon the delivery of the opinion as to the fairness of the transaction. The Company also agreed to reimburse Lehman for reasonable expenses related to its engagement, including fees for its legal advisors. The Company further agreed to indemnify Lehman for certain costs, expenses and liabilities related to or arising out of its engagement. Lehman Brothers, as part of its investment banking business, is continually engaged in financial advisory roles, which may include, but are not limited to, equity and fixed income sales, trading and research, investment banking, private equity, general corporate and other services. Lehman Brothers underwrote the Company's sale of 4.434 million shares of Common Stock in August 2003. In the ordinary course of business, Lehman Brothers and its affiliates may actively trade or hold the shares of Common Stock for their own account or for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities. ITEM 6. INTEREST IN SECURITIES OF THE SUBJECT COMPANY. On December 31, 2003, pursuant to the Company's Employee Stock Purchase Plan, Dr. Krause purchased 54 shares of the Company's Common Stock at a purchase price of $16.75 per share. On December 30, 2003, Mr. Thomas exercised options for 1,000 shares of the Company's Common Stock under the Company's 2000 Equity Compensation Plan, and paid cash for the exercise price of $5.00 per share.

(the "Company" or "Esperion"). You are receiving this Information Statement in connection with the possible election of persons designated by Pfizer Inc., a Delaware corporation ("Parent"), to at least a majority of seats on the Board of Directors of the Company (the "Board"). On December 19, 2003, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Parent and Enzo Acquisition Corp, a Delaware corporation and a wholly owned subsidiary of Parent ("Purchaser"), pursuant to which Purchaser is commencing a tender offer to purchase all outstanding shares of common stock, par value $0.001 per share, of the Company ("Common Stock"), at a price per share of $35.00, net to the seller in cash (the "Offer Price"), upon the terms and conditions set forth in Purchaser's Offer to Purchase, dated January 6, 2004, and in the related Letter of Transmittal (the "Letter of Transmittal" which, together with the Offer to Purchase and any amendments and supplements thereto, collectively constitute the "Offer"). Copies of the Offer to Purchase and the Letter of Transmittal have been mailed to stockholders of the Company and are filed as Exhibits to both the Schedule 14D-9 and the Tender Offer Statement on Schedule TO (as amended from time to time, the "Schedule TO") filed by Purchaser and Parent with the Securities and Exchange Commission on January 6, 2004. The Merger Agreement provides that, subject to the satisfaction or waiver of certain conditions, following completion of the Offer, and in accordance with Delaware law, Purchaser will be merged with and into the Company (the "Merger"). Upon consummation of the Merger, the Company will continue as the surviving corporation (the "Surviving Corporation") and will be a wholly owned subsidiary of Parent. At the effective time of the Merger (the "Effective Time"), each issued and outstanding share of Common Stock (other than shares of Common Stock that are owned by Parent, Purchaser, any of their respective wholly owned subsidiaries and the Company, and shares held by stockholders of the Company who do not tender their shares of Common Stock in the Offer and who have properly demanded and perfected appraisal rights under Section 262 of Delaware law) will be converted into the right to receive the Offer Price (or any adjusted price per Share paid in the Offer, as provided in the Merger Agreement), without interest thereon. The Offer, the Merger and the Merger Agreement are more fully described in the Schedule 14D-9 to which this Information Statement is attached as Annex A. The Schedule 14D-9 was filed by the Company with the Securities and Exchange Commission on January 6, 2004, and is being mailed to stockholders of the Company along with this Information Statement. This Information Statement is being mailed to you in accordance with Section 14(f) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 14f-1 promulgated thereunder. The information set forth herein supplements certain information set forth in the Schedule 14D-9. Information set forth herein related to Parent, Purchaser or the Parent Designees (as defined herein) has been provided by Parent. You are urged to read this Information Statement carefully. You are not, however, required to take any action in connection with the matters set forth herein. Pursuant to the Merger Agreement, Purchaser commenced the Offer on January 6, 2004. The Offer is scheduled to expire at midnight, New York City time, on February 4, 2004, unless extended by Purchaser in accordance with the terms of the Merger Agreement. A-1 GENERAL The Common Stock is the only class of equity securities of the Company outstanding that is entitled to vote at a meeting of the stockholders of the Company. Each share of Common Stock is entitled to one vote. As of January 2, 2004, there were 34,118,527 shares of Common Stock outstanding. See "Security Ownership of Certain Beneficial Owners and Management -- Security Ownership" below. RIGHT TO DESIGNATE DIRECTORS AND THE PARENT DESIGNEES THE BOARD OF DIRECTORS OF THE COMPANY. Pursuant to the Merger Agreement, subject to compliance with Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, effective upon Purchaser's acceptance for payment of, and payment for, shares of Common Stock pursuant to the Offer, Parent shall be entitled to designate such number of directors, rounded up to the next whole number, on the Board as is equal to the product of the total number of directors on the Board (determined after giving effect to the directors elected pursuant to this sentence) multiplied by the percentage that the aggregate number of shares of Common Stock beneficially owned by Parent or Purchaser bears to the total number of shares of Common Stock then outstanding (the "Parent Designees"). At such time, the Company is obligated to take all actions necessary to cause the Parent Designees to be elected to the Board, including increasing the number of directors and seeking and accepting the resignation of one or more existing directors. The Company has also agreed to use its reasonable best efforts to cause the Board's committees, the board of directors of each of the Company's subsidiaries and each committee of each such board to include Parent Designees constituting the same percentage of each such board or committee as the Parent Designees are of the Board. However, even if the Parent Designees are elected to the Board, until the Effective Time, the Company, Parent and Purchaser have agreed that the Board shall include at least two Continuing Directors (as defined below), and the Company has agreed to use its reasonable best efforts to ensure that the Board includes two Continuing Directors. Continuing Directors are directors of the Company who are not officers, employees or affiliates of the Company and who are independent directors of the Company as defined by the listing standards of The Nasdaq National Market.

EMPLOYMENT, CHANGE OF CONTROL, AND TERMINATION OF EMPLOYMENT ARRANGEMENTS Roger S. Newton, Ph.D., Timothy M. Mayleben, Brian R. Krause, Ph.D., Jean-Louis H. Dasseux, Ph.D. and William F. Brinkerhoff, respectively, are employed by the Company pursuant to letter agreements. Pursuant to Dr. Newton's letter agreement, Dr. Newton also became a member of the Board of Directors of the Company. Dr. Newton's letter agreement specifies an initial annual base salary amount, which has been increased since the date of the agreement, and the right to receive an annual bonus in an amount equal to up to 30% of annual base salary. The letter agreements with Mr. Mayleben (dated November 25, 1998), A-13 Dr. Krause (dated February 2, 2001, as amended on November 24, 2003), Dr. Dasseux (dated December 9, 1998) and William F. Brinkerhoff (dated April 19, 2002), specify an initial base salary and the right to receive an annual bonus in the amount equal to up to 20% of annual base salary (collectively, the "Officers"). The amount of the annual bonus, if any, is determined by the Board and is dependent upon achievement of a series of performance milestones set by the Board in Dr. Newton's case, or the supervisor of the Officer, in the case of each Officer. The letter agreements generally provide for a review of performance on an annual basis, possible adjustment, in the discretion of the Board, of base salary and bonus amounts, and the granting of stock options, at the discretion of the Board, in recognition of performance for the preceding year. In addition, pursuant to the letter agreements, Dr. Newton and each of the Officers are provided with a benefits package similar to that offered to the Company's other similarly situated employees. Under the terms of their Letter Agreements, Mr. Mayleben, Dr. Krause, Dr. Dasseux and Mr. Brinkerhoff received options to purchase 72,250, 80,000, 36,125 and 75,000 shares of Common Stock, respectively. Each of those options vest on a quarterly basis over the four-year period from the grant date and are exercisable for a nine-year or ten-year period from the grant date. Pursuant to Dr. Newton's letter agreement, Dr. Newton received 578,000 shares of restricted Common Stock that were subject to a right of repurchase by the Company that was exercisable upon the termination of employment. The repurchase price of such restricted shares was equal to the original purchase price of such shares. The Company's repurchase rights lapsed on a quarterly basis over a four-year period and expired on June 26, 2002. The employment relationships of Dr. Newton and each Officer with the Company are that of employment at will. If, however, the Company terminates the employment of Dr. Newton, Mr. Mayleben, Dr. Dasseux, Dr. Krause or Mr. Brinkerhoff without cause, the terminated officer will receive his salary and benefits for six months after his termination, and 25% of such officer's unvested options will automatically vest. In connection with the letter agreements, Dr. Newton and each of the Officers entered into non-competition and confidentiality agreements with the Company. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION Until the end of his term as a director at the annual meeting of stockholders held on May 30, 2003, David I. Scheer, the former Chairman of the Board of the Company, was a member of the Compensation Committee and received compensation under a consulting arrangement between the Company and Scheer & Company, Inc., a company owned and controlled by Mr. Scheer. Under the arrangement, Scheer & Company was paid a cash retainer of $30,000 per quarter, payable quarterly in advance, plus expenses. During fiscal year 2002, Scheer & Company was paid $150,000 in fees ($30,000 of which was incurred in 2001) and $10,717 in expense reimbursements ($1,862 of which was incurred in 2001) under the arrangement. In addition, Scheer & Company had the right to receive under certain circumstances a transaction fee of 1% of specified cash consideration that the Company receives in a financial transaction. These arrangements were superseded by an agreement dated April 2003 (the "Agreement"). Under the Agreement, Scheer & Company, Inc. is to be paid a total of $90,000 during 2003, plus certain expenses for consulting services. In addition, pursuant to the Agreement, Scheer & Company, Inc. has the right to receive a transaction fee of 0.85% of specified cash consideration received by the Company in a transaction with a company identified by the Company and Scheer & Company, Inc. for which a definitive agreement is executed within 24 months of the effective date of the Agreement. A-14 COMPARATIVE STOCK PERFORMANCE The following graph compares the change in the total stockholder return on shares of common stock during the period from August 10, 2000, the date the Company became a public company, through December 31, 2003, with the total return on the Nasdaq Composite Index (U.S.), the Nasdaq Biotechnology Index, and the AMEX Biotechnology Index. The comparison assumes that $100 was invested on August 10, 2000 in shares of common stock and in each of the foregoing indices and assumes reinvestment of dividends, if any.

Dasseux, Ph.D., an executive officer of the Company, and the other inventors of the RLT Peptide-related technology. Under the license agreement, the Company obtained an exclusive license to the RLT Peptide technology and related U.S. and foreign patents for a term expiring on the later of ten years or the last expiration date of the licensed patents. Under the terms of the license agreement, the Company is required to make payments to the licensors upon the achievement of certain milestones. If all of the milestones set forth in the license agreement are achieved, the total amount payable by the Company to the licensors, including Dr. Dasseux, would be approximately $2,165,000. Royalties are also payable by the Company under the license agreement. During fiscal year 2003, the Company did not make any payments to Dr. Dasseux or the other inventors pursuant to the license agreement.

A-19 ANNEX B [LETTERHEAD OF LEHMAN BROTHERS] December 19, 2003 Board of Directors Esperion Therapeutics, Inc. 3621 South State Street 695 KMS Place Ann Arbor, MI 48108 Members of the Board: We understand that Esperion Therapeutics, Inc. (the "Company") intends to enter into an agreement with Pfizer Inc. ("Pfizer") pursuant to which Pfizer will cause Enzo Acquisition Corp., a wholly owned subsidiary of Pfizer ("Acquisition Sub"), to purchase all of the issued and outstanding shares of the Company's common stock for $35.00 per share in cash by means of a tender offer and subsequent merger of Acquisition Sub with and into the Company (the "Proposed Transaction"). The terms and conditions of the Proposed Transaction are set forth in more detail in the Agreement and Plan of Merger, and the License Agreement Amendment, each dated December 19, 2003 among the Company, Pfizer and Acquisition Sub (the "Agreement" and the "License Agreement Amendment"). We have been requested by the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the Company's stockholders of the consideration to be offered to such stockholders in the Proposed Transaction. We have not been requested to opine as to, and our opinion does not in any manner address, the Company's underlying business decision to proceed with or effect the Proposed Transaction. In arriving at our opinion, we reviewed and analyzed: (1) the Agreement, the License Agreement Amendment and the specific terms of the Proposed Transaction, (2) publicly available information concerning the Company that we believe to be relevant to our analysis, including the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2002 and the Company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2003, (3) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company, including long-term financial projections for the Company (the "Company Projections"), (4) the trading history of the Company's common stock from December 18, 2002 to the present and a comparison of that trading history with those of other companies that Lehman Brothers deemed relevant, (5) independent research analysts' estimates of the future financial performance and share price targets of the Company, (6) a comparison of the historical financial results and present financial condition of the Company with those of other companies that we deemed relevant, (7) a comparison of the financial terms of the Proposed Transaction with the financial terms of certain other transactions that we deemed relevant, and (8) the results of efforts by the Company to solicit indications of interest from third parties with respect to a strategic collaboration or transaction with the Company. In addition, we have had discussions with the management of the Company concerning its business, operations, assets, financial condition, prospects, and stockholder base, and have undertaken such other studies, analyses and investigations as we deemed appropriate. In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without assuming any responsibility for independent verification of such information and have further relied upon the assurances of the management of the Company that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the Company Projections, upon the advice of the Company, we have assumed that such projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the Company's management as to the long-term future financial performance of the Company, and we have relied upon such projections in performing our analysis. In arriving at our opinion, we have conducted a limited B-1 physical inspection of the properties and facilities of the Company and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter. Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the consideration to be offered to the Company's stockholders in the Proposed Transaction is fair to such stockholders. We have acted as financial advisor to the Company in connection with the Proposed Transaction and will receive a fee for our services, which is contingent upon the consummation of the Proposed Transaction. We have also performed various investment banking services for the Company in the past and have received customary fees for such services. In addition, the Company has agreed to indemnify us for certain liabilities that may arise out of the rendering of this opinion. In the ordinary course of our business, we actively trade in the equity securities of the Company for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities. This opinion is for the use and benefit of the Board of Directors of the Company and is rendered to the Board of Directors in connection with its consideration of the Proposed Transaction. This opinion is not intended to be and does not constitute a recommendation to any stockholder of the Company as to whether to accept the consideration to be offered to the Company's stockholders in connection with the Proposed Transaction. Very truly yours, LEHMAN BROTHERS B-2
