FURTHER, that Hexcel shall exercise all authority under applicable law, rule and
regulation to permit the inclusion of any Investor Director designated by the

member of the Board resigns (pursuant to this Section 2.05 or

                                       13
<Page>

otherwise) or is removed in accordance with applicable law or Hexcel's by-laws,
a new member shall be designated to replace such member until the next election
of directors. If consistent with Section 2.02 the replacement director is to be
an Investor Director, the party that designated such Investor Director shall
designate the replacement Investor Director. Except as set forth in paragraph
(c) below, if consistent with Section 2.02, the replacement director is to be a
Non-Investor Director, such Non-Investor Director (including the Chairman of the
Board if he or she is a Non-Investor Director) shall be designated in accordance
with the terms of this Agreement.

     (b)  Subject to paragraph (c) below, if at any time the number of Investor
Nominees entitled to be nominated to the Board in accordance with this Agreement
in an election of directors presented to stockholders would decrease, within 10
days thereafter the Investors shall cause a sufficient number of Investor
Directors to resign from the Board so that the number of Investor Directors on
the Board after such resignation(s) equals the number of Investor Nominees that
the Investors would have been entitled to designate had an election of directors
taken place at such time. The Investors shall also cause a sufficient number of
Investor Directors to resign from any relevant committees of the Board so that
such committees are comprised in the manner contemplated by Section 2.04 after
giving effect to such resignations. Any vacancies created by the resignations
required by this Section 2.05(b) shall be filled by Independent Directors.

     (c)  If at any time the percentage of the Total Voting Power of Hexcel
Beneficially Owned by the Investors decreases as a result of an issuance of
Voting Securities by Hexcel (other than any of the issuances described in the
last sentence of this Section 2.05(c)), the Investors may notify Hexcel that the
Investors intend to acquire a sufficient amount of additional Voting Securities
in accordance with this Agreement necessary to maintain their then current level
of Board representation within 90 days. In such event, until the end of such
period (and thereafter if the Investors in fact restore their percentage of the
Total Voting Power of Hexcel during such period and provided that the Investors
continue to maintain the requisite level of Beneficial Ownership of Voting
Securities in accordance with Section 2.02) the Board shall continue to have the
number of Investor Directors that corresponds to the percentage of the Total
Voting Power of Hexcel Beneficially Owned by the Investors prior to such
issuance of Voting Securities by Hexcel. Notwithstanding any provision herein to
the contrary, the provisions of this Section 2.05(c) shall not apply to any
issuances of Voting Securities (x) upon conversion of any convertible

                                       14

limitation, issuances of securities upon any payment of dividends on, redemption
of, or otherwise payable with respect to the Series A Convertible Preferred
Stock or Series B Convertible Preferred Stock) or approved by the Board or a
duly authorized committee of the Board after the date hereof in accordance with
Section 2.06 hereof, or (y) pursuant to employee or director stock option or
incentive compensation or similar plans outstanding as of the date hereof or,
subsequent to the date hereof, approved by the Board or a duly authorized

Hexcel is reduced below 15% by an issuance of Voting Securities by Hexcel, no
such authorization, approval, or ratification shall be given by the Board
without the approval of a majority of the Investor Directors (x) until 10
business days after Hexcel notifies the Investors in writing of such issuance,
and (y) if the Investors shall have notified Hexcel within 10 business days
after their receipt of a written notification of such issuance that the

such 90-day period, subject to Section 2.05(c), during the 90-day period
following an issuance of Voting Securities by Hexcel that causes the Investors
to Beneficially Own less than 15% of the Total Voting Power of Hexcel:

of Voting Securities. Except as provided above and in Section 3.03, the
Investors shall be free to vote in their sole discretion all their Voting
Securities entitled to vote on any other matter submitted to or acted upon by
stockholders; PROVIDED, HOWEVER, that the Investors shall vote against any
amendment to Hexcel's certificate of incorporation with respect to the
directors' and officers' indemnification provisions contained therein which
would adversely affect the rights thereunder of the Indemnified Individuals at

the Investors shall each take or cause to be taken all lawful action necessary
to ensure at all times that Hexcel's certificate of incorporation and by-laws

     (b)  Except with the Investors' prior written consent, Hexcel shall not
cause or permit any amendment, restatement, modification or change to, or waiver
of, any provision contained in any agreement (other than customary employee or
director stock option or incentive compensation or similar plans approved by the

Securities held by such holder or holders or (2) registration rights with
respect to Voting Securities held by such holder or holders.

     (c)  Except as required by applicable law, rule or regulation, Hexcel shall
not approve or recommend to its stockholders any transaction or approve,
recommend or take any other action (other than those expressly contemplated by
this Agreement and other than those that affect the Investors and each Other
Holder or each director at the same time in the same manner) that would (1)
materially adversely discriminate against the Investors as stockholders of
Hexcel or (2) restrict the right of any Investor Director to vote on any matter
as such director believes appropriate in light of his or her duties as a
director or the manner in which an Investor Director may participate in his or
her capacity as a director in deliberations or discussions at meetings of the
Board or any committee thereof, except with respect to (i) entering into
contractual or other business relationships with any of the Investors or any of
their Affiliates (other than in their capacity as stockholders of Hexcel), (ii)

instrument, nor amend the Debt Instruments or other material agreements and
instruments to which it is a party in such a manner, that would (i) prohibit any
Investor from acquiring the Acquisition Shares or (ii) cause an Investor's
acquisition of Acquisition Shares to conflict with, or cause Hexcel to breach or
violate, the terms of any such agreement or instrument. Notwithstanding the
foregoing, Hexcel may adopt or implement any takeover defense measures
applicable to the Investors or any of their Affiliates, including the
institution or amendment by Hexcel or any of its Subsidiaries of any
stockholders rights plan or similar plan or device, or any change of control
matters (including provisions in future agreements or collaborations), PROVIDED,
that such takeover defense measures

                                       18

shall not restrict the rights of the Investors to acquire any Voting Securities
pursuant to the provisions of this Agreement.

          SECTION 3.02    INVESTORS RIGHT TO MAINTAIN POSITION. In addition to
the rights set forth in Sections 2.05(c) and 2.06 hereof, Hexcel hereby grants
to the Investors the following irrevocable option:

     If, at any time after the Closing Date for so long as the Investors shall
be entitled to designate one or more Investor Nominees for election to the Board
and Hexcel shall issue for cash any additional Voting Securities, then Hexcel
shall notify the Investors of such issuance and the price and terms thereof, and
the Investors shall have the option, for a period of 45 days after receipt of
such notice, to purchase from Hexcel an Amount (as defined below) of such Voting
Securities for the same consideration per security and on the same terms as were
applicable to such issuance by Hexcel. The foregoing option shall not apply to
any issuances of Voting Securities (x) upon conversion of any convertible
securities which are either outstanding on the date hereof (including, without
limitation, issuances of securities upon any payment of dividends on, redemption
of, or otherwise payable with respect to the Series A Convertible Preferred
Stock or the Series B Convertible Preferred Stock) or approved by the Board or a

Section 2.06 hereof, or (y) pursuant to employee or director stock option or
incentive compensation or similar plans outstanding as of the date hereof or,
subsequent to the date hereof, approved by the Board or a duly authorized
committee of the Board. An "Amount" shall mean such number of securities that
would allow the Investors to Beneficially Own the same percentage of

                                       22
<Page>

the Total Voting Power of Hexcel as the Investors Beneficially Owned immediately

majority of Disinterested Directors, including the approval of at least two
Independent Directors, the Investors may act at their sole discretion with
respect to such Third Party Offer.

     (b)  In the event that Hexcel becomes the subject of a Third Party Offer

such Third Party Offer is (i) not approved by a majority of the Board or (ii)
approved by a majority of the Board but not by a majority of the Disinterested
Directors, including the approval of at least two Independent Directors, none of
the Investors nor any of their respective Affiliates (other than with respect to
Additional Shares) may support such Third Party Offer, vote in favor of such
Third Party Offer or tender or sell their Voting Securities to the Person making
such Third Party Offer.

     (c)  In the event that Hexcel becomes the subject of a Third Party Offer or
an Investor Buyout Transaction that is made after the date that is eighteen
months from the Closing Date and such Third Party Offer or Investor Buyout
Transaction is (i) not approved by a majority of the Board or (ii) approved by a
majority of the Board but not by a majority of the Disinterested Directors,
including the approval of at least two Independent Directors, the Investors and
each of their respective Affiliates (other than with respect to Additional
Shares) must vote all of their Voting Securities against such Third Party Offer
or Investor Buyout Transaction in proportion to the votes cast against such
Third Party Offer or Investor Buyout Transaction with respect to Other Shares
and may not tender or sell their Voting Securities to the Person making such
Third Party Offer or Investor Buyout Transaction in a proportion greater than
the tenders or sales made by the Other Holders to the Person making such Third
Party Offer or Investor Buyout Transaction; it being understood that the
Investors may enter into agreements to tender or sell Voting Securities to any
such Person conditioned upon final determination of the number of Voting
Securities permitted to be so tendered or sold under this Section 3.03 and
Section 3.01.

          SECTION 6.04    COUNTERPARTS. This Agreement may be executed in one or

Agreement, together with the Purchase Agreement, the Registration Rights

of Designations (a) constitutes the entire agreement and supersedes all prior

SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
DELAWARE (WITHOUT GIVING EFFECT TO CONFLICT OF LAWS PRINCIPLES THEREOF). The
parties hereto agree that irreparable damage would occur in the event that any
of the provisions of this Agreement were not performed in accordance with its
specific terms or was otherwise breached. It is accordingly agreed that the
parties hereto shall be entitled to an injunction or injunctions and other
equitable remedies to prevent breaches of this Agreement and to enforce
specifically the terms and provisions hereof in any of the Selected Courts (as
defined below), this being in addition to any other remedy to which they are
entitled at law or in equity. Any requirements for the securing or posting of
any bond with respect to such remedy are hereby waived by each of the parties
hereto. Each party further agrees that, in the event of any action for an
injunction or other equitable remedy in respect of such breach or enforcement of
specific performance, it will not assert the defense that a remedy at law would
be adequate.

          SECTION 6.08    CONSENT TO JURISDICTION. With respect to any suit,
action or proceeding ("Proceeding") arising out of or relating to this

                                       29
<Page>

Agreement or any transaction contemplated hereby each of the parties hereto
hereby irrevocably (i) submits to the exclusive jurisdiction of the United
States District Court for the Southern District of New York or the Court of
Chancery located in the State of Delaware, County of Newcastle (the "Selected
Courts") and waives any objection to venue being laid in the Selected Courts
whether based on the grounds of forum non conveniens or otherwise and hereby
agrees not to commence any such Proceeding other than before one of the Selected
Courts; PROVIDED, HOWEVER, that a party may commence any Proceeding in a court
other than a Selected Court solely for the purpose of enforcing an order or
judgment issued by one of the Selected Courts; (ii) consents to service of
process in any Proceeding by the mailing of copies thereof by registered or
certified mail, postage prepaid, or by recognized international express carrier
or delivery service, to the Company or the Investors at their respective
addresses referred to in Section 6.01 hereof; PROVIDED, HOWEVER, that nothing
herein shall affect the right of any party hereto to serve process in any other
manner permitted by law; and (iii) TO THE EXTENT NOT PROHIBITED BY APPLICABLE
LAW THAT CANNOT BE WAIVED, WAIVES, AND COVENANTS THAT IT WILL NOT ASSERT
(WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE) ANY RIGHT TO TRIAL BY JURY IN ANY
ACTION ARISING IN WHOLE OR IN PART UNDER OR IN CONNECTION WITH THIS AGREEMENT OR
ANY OF THE CONTEMPLATED TRANSACTIONS, WHETHER NOW EXISTING OR HEREAFTER ARISING,
AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE, AND AGREE THAT ANY OF THEM
MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE
KNOWING, VOLUNTARY AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO
WAIVE ITS RIGHT TO TRIAL BY JURY IN ANY PROCEEDING WHATSOEVER BETWEEN THEM
RELATING TO THIS AGREEMENT OR ANY OF THE CONTEMPLATED TRANSACTIONS WILL INSTEAD
BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

          SECTION 6.09    AMENDMENTS; WAIVERS. (a) No provision of this
Agreement may be amended or waived unless such amendment or waiver is in writing
and signed, in the case of an amendment, by the parties hereto, or in the case
of a waiver, by the party against whom the waiver is to be effective; PROVIDED
that no such amendment or waiver by Hexcel shall be effective without the
approval of a majority of the Independent Directors. Notwithstanding any
provision herein to

                                       30
<Page>

the contrary, if a majority of the Independent Directors determine in good faith
to do so, such Independent Directors may seek to enforce, in the name and on
behalf of Hexcel, the terms of this Agreement against the Investors.

     (b)  No failure or delay by any party in exercising any right, power or
privilege hereunder shall operate as waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

          SECTION 6.10    ASSIGNMENT. Neither this Agreement nor any of the
rights or obligations hereunder shall be assigned by any of the parties hereto
without the prior written consent of the other parties. Subject to the preceding
sentence, this Agreement will be binding upon, inure to the benefit of and be
enforceable by the parties and their respective successors and assigns.

          SECTION 6.10    VENTURE CAPITAL OPERATING COMPANY MATTERS. Each of
Berkshire Fund VI and Greenbriar Fund shall have rights to substantial
participation in the management of the Company solely by acting through their
respective rights to each appoint a member to the Board of Directors pursuant to
