In early 2007, the OSS Group contacted the Company to discuss ways in which to maximize stockholder value at Hexcel. On March 9, 2007, O.S.S. Capital Management LP (the "Investment Manager") sent a letter to the Company expressing its concern regarding the Company's operating performance relative to its peers and regarding the perceived lack of concern with this gap in performance by management. The Investment Manager also noted that a member of the Company's Board of Directors was stepping down and suggested a candidate for his replacement. The Company did not accept the suggested candidate. On April 9, 2007, the Company's Chief Executive Officer met with representatives of the Investment Manager at its offices. In a letter dated April 26, 2007, the OSS Group reiterated the underperformance of the Company as its main concern, as raised during the April 9, 2007 meeting. The Investment Manager requested a committee of independent directors be formed and that the committee retain an independent investment bank to advise as to how stockholder value could best be maximized. Subsequently, on May 10, 2007, the OSS Group made a presentation of its analysis of the Company's operating performance to the Company's Board of Directors. In the following months, the Company took no further action to meet with the OSS Group, to implement the strategies previously suggested or to provide any feedback regarding the May presentation. On July 25, 2007, the Investment Manager sent another letter to the Company expressing its frustration regarding the Company's lack of responsiveness following the May presentation. Additionally, the Investment Manager referenced the decline in the Company's gross margin percentage despite a sales increase. In the letter the Investment Manager also reiterated its concerns that: (1) the Company is underperforming, (2) the Company's management is not addressing the shortfall in earnings and (3) the stockholders are suffering as a result. The Investment Manager again requested a committee of independent directors be formed and that the committee retain an independent investment bank to advise as to how stockholder value could be best maximized. The Investment Manager contacted the Company on October 22, 2007 to suggest several candidates for consideration by the Company for appointment or election to the Board of Directors. The Company did not accept the suggested candidates. On November 26, 2007 OSS II sent a notice to the Company, (the "Notice") declaring its intention to nominate the following three persons for election to the Board of Directors of the Company at the Company's 2008 Annual Meeting: Mr. Edward A. Blechschmidt; Mr. Timothy D. Leuliette; and Mr. Joachim V. Hirsch. OSS II also delivered to the Company a demand to inspect the Company's stockholder list and related materials, pursuant to Section 220 of the Delaware General Corporation Law. OSS II also disclosed that it and certain of its affiliates and parties related thereto intended to file preliminary proxy materials with the U.S. Securities and Exchange Commission (the "SEC") and to solicit proxies in support of the election of the Nominees at the Company's 2008 Annual Meeting. Following the Notice, the Company notified the OSS Group that the Company's Nominating and Corporate Governance Committee (the "Committee") would consider the Nominees pursuant to its routine practice. The Nominees fully cooperated with the Committee's process. On February 19, 2008, the Company notified the OSS Group that it was willing to nominate only one of three Nominees to the Board. On that same day, and as confirmed by letter dated February 25, 2008, the OSS Group advised the Company that its offer would not result in sufficient change in the composition of the Board and accordingly that the OSS Group intended to proceed with this proxy solicitation. PROPOSAL 1: ELECTION OF DIRECTORS According to the Company's 2007 proxy statement, ten directors are to be elected to the Board at the 2008 Annual Meeting. We recommend that stockholders elect Edward A. Blechschmidt, Timothy D. Leuliette and Joachim V. Hirsch as directors of the Company at the 2008 Annual Meeting. Each of our Nominees has consented to being named as a Nominee and to serving as a director if elected. If elected, each Nominee will serve until the next annual meeting of stockholders and until his successor shall have been duly elected and qualified or until his earlier death, resignation or removal. If elected, each of our Nominees will be considered an independent director of the Company under applicable New York Stock Exchange rules. The OSS Group believes good corporate governance requires that the Board be comprised of independent-minded directors, not tied to management, who bring a diverse set of relevant skills and experience to their board service. Accordingly, the OSS Group has proposed three highly qualified nominees who have the independence from management as well as the experience required to improve oversight in this underperforming company. Each of the Nominees has an extensive, successful business background with significant leadership experience and will be dedicated to maximizing stockholder value. Under the Company's Bylaws, a quorum for the transaction of business requires a majority of the directors in office and Board action requires a majority of the directors present at a meeting at which a quorum is present. Accordingly, our Nominees, if elected, will not be able to take Board action at a meeting of the full Board without the support of at least three other directors. Our Nominees are receiving compensation from the OSS Group of $50,000 each in consideration for their services during the period from their agreeing to be nominees until the 2008 Annual Meeting. If elected, our Nominees will receive no further compensation from the OSS Group but will be entitled to such compensation from the Company as is consistent with the Company's past practices for services of non-employee directors, which is described in the Company's proxy statement. The OSS Group also intends to vote for the candidates who have been nominated by the Company other than , and . You should refer to the proxy statement and form of proxy distributed by Hexcel for the names, background, qualifications and other information concerning Hexcel's candidates. There is no assurance that any of Hexcel's nominees will serve as directors if any of the OSS Group's nominees are elected to the Board. In the event that one or more of our Nominees is elected and that one or more of the Hexcel nominees declines to serve with such nominee or nominees, the Company's ByLaws provide that director vacancies may be filled by the remaining directors then in office, unless sooner filled by stockholders. THIS SOLICITATION IS BEING MADE BY THE OSS GROUP AND NOT ON BEHALF OF THE BOARD OR MANAGEMENT OF THE COMPANY.

If you were a stockholder of record on the Record Date, you will retain your voting rights at the 2008 Annual Meeting even if you sell your Shares after the Record Date. Accordingly, it is important that you vote the Shares held by you on the Record Date, or grant a proxy to vote your Shares on the WHITE proxy card, even if you sell your Shares after the Record Date. The Shares represented by each WHITE proxy card that is properly executed and returned to the OSS Group will be voted at the 2008 Annual Meeting in accordance with the instructions marked thereon. If you have signed the WHITE proxy card and no marking is made, you will be deemed to have given a direction to vote all of the Shares represented by the WHITE proxy card FOR (i) the election of all of our Nominees and for the candidates who have been nominated by the Company other than , and and (ii) the ratification of the Board's appointment of the Accountants as the Company's independent registered public accounting firm for 2008 and to authorize the Audit Committee to set the independent auditors' remuneration. There is no assurance that any of Hexcel's nominees will serve as directors if any of the OSS Group's Nominees are elected to the Board. In addition, a proxy card will be voted in the proxy holders' discretion with respect to such other matters as may properly come before the meeting. If you hold your Shares in the name of one or more brokerage firms, banks or nominees, only they can vote your Shares and only upon receipt of your specific instructions. Accordingly, you should contact the person responsible for your account and give instructions for a WHITE proxy card representing your Shares to be signed and returned. The OSS Group urges you to confirm in writing your instructions to the person responsible for your account and to provide a copy of those instructions to The OSS Group, c/o MacKenzie Partners, Inc. 105 Madison Avenue, New York, New York 10016, so that we will be aware of all instructions given and can attempt to ensure that those instructions are followed. REVOCATION OF PROXIES Any stockholder of record may revoke or change his or her proxy instructions at any time prior to the vote at the 2008 Annual Meeting by: o submitting a properly executed, subsequently dated WHITE proxy card (including an Internet or telephone vote) that will revoke all prior proxy cards, including any [COLOR HEXCEL] proxy cards which solicit a proxy in favor of all of the incumbent directors; o attending the 2008 Annual Meeting and withdrawing his or her proxy by voting in person (although attendance at the 2008 Annual Meeting will not in and of itself constitute revocation of a proxy); o following the voting instructions on the WHITE proxy card or the voting instructions provided by your broker, bank or other holder of record to properly submit a vote by Internet or telephone; which will revoke all prior proxy cards, including any [COLOR HEXCEL] proxy cards; or o delivering written notice of revocation either to the OSS Group c/o MacKenzie Partners, Inc., 105 Madison Avenue, New York, New York 10016, or the Corporate Secretary of Hexcel at Two Stamford Plaza, 281 Tresser Boulevard, Stamford, Connecticut 06901, or any other address provided by the Company. Although a revocation is effective if delivered to the Company, the OSS Group requests that either the original or a copy of any revocation be mailed to the OSS Group c/o MacKenzie Partners, Inc., 105 Madison Avenue, New York, New York 10016, so that the OSS Group will be aware of all revocations and can more accurately determine if and when the requisite proxies for the election of our Nominees as directors set forth herein have been received. The OSS Group may contact stockholders who have revoked their proxies. IF YOU PREVIOUSLY SIGNED AND RETURNED A [COLOR HEXCEL] PROXY CARD TO THE COMPANY, THE OSS GROUP URGES YOU TO REVOKE IT BY (1) SIGNING, DATING AND RETURNING THE WHITE PROXY CARD IN THE ENCLOSED POSTAGEPAID ENVELOPE, (2) INSTRUCTING US BY TELEPHONE OR VIA THE INTERNET AS TO HOW YOU WOULD LIKE YOUR SHARES VOTED, (3) ATTENDING THE 2008 ANNUAL MEETING AND VOTING IN PERSON OR (4) DELIVERING A WRITTEN NOTICE OF REVOCATION TO THE OSS GROUP OR TO THE SECRETARY OF THE COMPANY.

Only stockholders of record at the close of business on the Record Date will be entitled to vote at the 2008 Annual Meeting. Each Common Share has one vote. Stockholders of the Company will not have rights of appraisal or similar dissenter's rights with respect to any matter to be acted upon at the 2008 Annual Meeting.
