                             PERFORMANCE ACCELERATED
                         RESTRICTED STOCK UNIT AGREEMENT
                                December 2, 1999

              This Performance  Accelerated Restricted Stock Unit Agreement (the
"Agreement"),  is  entered  into as of the Grant  Date,  by and  between  Hexcel
Corporation, a Delaware corporation (the "Company"), and the Grantee.

              Pursuant  to the  Hexcel  Corporation  Incentive  Stock  Plan (the
"Plan"), the Executive  Compensation Committee (the "Committee") of the Board of
Directors of the Company (the "Board") has determined  that the Grantee shall be
granted Performance  Accelerated  Restricted Stock Units ("PARS") upon the terms
and subject to the conditions hereinafter contained.  Capitalized terms used but
not defined herein shall have the meanings assigned to them in the Plan.

              1. Notice of Grant;  Incorporation  of Plan.  A Notice of Grant is
attached  hereto  as  Annex  A and  incorporated  by  reference  herein.  Unless
otherwise  provided  herein,  capitalized  terms used in this  Agreement and set
forth in the Notice of Grant  shall have the  meanings  ascribed  to them in the
Notice of Grant and  capitalized  terms used in this  Agreement and set forth in
the Plan  shall  have the  meanings  ascribed  to them in the Plan.  The Plan is
incorporated by reference and made a part of this Agreement,  and this Agreement
shall be subject to the terms of the Plan,  as the Plan may be amended from time
to time, provided that any such amendment of the Plan must be made in accordance
with Section X of the Plan. The PARS granted  herein  constitute an Award within
the meaning of the Plan.

          2. Terms of Restricted  Stock. The grant of PARS provided in Section 1
hereof shall be subject to the following terms, --------------------------
conditions and restrictions:

     (a)  The Grantee shall not possess any  incidents of ownership  (including,
          without  limitation,  dividend and voting  rights) in shares of Common
          Stock in  respect  of the PARS  until  such PARS have  vested and been
          distributed to the Grantee in the form of shares of Common Stock.

     (b)  Except as provided in this  Section 2 (b),  the PARS and any  interest
          therein may not be sold, assigned, transferred,  pledged, hypothecated
          or otherwise  disposed  of,  except by will or the laws of descent and
          distribution, prior to the distribution of the Common Stock in respect
          of such PARS and subject to the  condi-tions set forth in the Plan and
          this Agreement.  Any attempt to transfer PARS in contravention of this
          Section  is void ab initio.  PARS  shall not be subject to  execution,
          attachment  or  other  process.  Notwithstanding  the  foregoing,  the
          Grantee  shall be permitted to transfer PARS to members of this or her
          immediate family (i.e., children, grandchildren or spouse), trusts for
          the  benefit  of such  family  members,  and  partnerships  whose only
          partners  are  such  family  members;   provided,   however,  that  no
          consideration  can be  paid  for  the  transfer  of the  PARS  and the
          transferee of the PARS shall be subject to all  conditions  applicable
          to the  PARS  (including  all of the  terms  and  conditions  of  this
          Agreement) prior to transfer.

              3.  Vesting  and  Conversion  of PARS.  The PARS shall vest on (a)
January 1, 2007,  or (b) on an earlier date when the closing price of a share of
Company  Common  Stock as reported on the New York Stock  Exchange  Consolidated
Transactions  Tape  shall  equal or  exceed  $12 for any ten days out of  thirty
consecutive trading days. Upon the later to occur of (i) January 1, 2003 or (ii)
the vesting of the PARS,  such vested PARS shall be converted into an equivalent
number of shares of Common  Stock that will be  immediately  distributed  to the
Grantee;  provided,  however,  that,  to the extent that (and only to the extent
that) the Company would be precluded from deducting the associated  compensation
expense  because of Section  162(m) of the  Internal  Revenue  Code of 1986,  as
amended  (the  "Code"),  such PARS shall be  converted  and  distributed  to the
Grantee on the first  business  day of the first  year (or  years,  if the first
deferred  distribution  shall not include all of such PARS) in which the Company
will not be so precluded;  and provided further, that no PARS shall be converted
and  distributed to the Grantee unless the Grantee is an employee of the Company
(or a  Subsidiary)  on December 31,  2002.  On each  dividend  payment date with
respect to the Common Stock subsequent to any PARS becoming fully vested but not
yet converted and  distributed by virtue of the immediately  preceding  proviso,
the Company shall credit the Grantee with an  additional  number of fully vested
whole  and  partial  PARS  (assuming  each  such PARS unit was a share of Common
Stock)  equal in value to the amount of dividends  which the Grantee  would have
received on such dividend  payment date if all such vested PARS  (including PARS
previously  credited to the Grantee  pursuant to this section) which had not yet
been  converted  into shares had been so  converted  prior to the record date of
such dividend.  Such dividends will be credited as vested PARS as of the payment
date of such  dividends and such vested PARS shall  thereafter be treated in the
same manner as other PARS under this Agreement (the foregoing method of dividend
crediting  being  referred  to  herein  as being  credited  with  the  "Dividend
Equivalent").

                                      162
<PAGE>

              Upon the  distribution of the shares of Common Stock in respect of
the PARS,  the  Company  shall issue to the  Grantee or the  Grantee's  personal
representative  a stock  certificate  representing  such shares of Common Stock,
free of any restrictions.

              4.      Termination of Employment; Change of Control.

     (a)  For purposes of the grant hereunder, any transfer of employment by the
          Grantee among the Company and its Subsidiaries shall not be considered
          a termi-nation  of  employment.  Notwithstanding  any other  provision
          contained herein or in the Plan, (i) if the Grantee dies or terminates
          employment due to Disability (as defined in the last Section  hereof),
          all PARS shall vest,  be converted  into shares of Common Stock and be
          immediately   distributed  to  the  Grantee,  (ii)  if  the  Grantee's
          employment with the Company is involuntarily terminated other than for
          Cause (as defined in the last Section hereof), all PARS shall vest, be
          converted into shares of Common Stock and be  immediately  distributed
          to the Grantee, (iii) if the Grantee voluntarily terminates employment
          with the Company,  all vested PARS shall be  converted  into shares of
          Common Stock and be immediately  distributed to the Grantee,  provided
          that the Grantee is an employee  of the Company (or a  Subsidiary)  on
          December  31,  2002,  and (iv) if the  Grantee's  employment  with the
          Company terminates due to the Grantee's  Retirement (as defined in the
          last Section  hereof),  all PARS shall vest, be converted in shares of
          Common Stock and be immediately distributed to the Grantee;  provided,
          however,  that in each case an  appropriate  number of such PARS shall
          not be  converted  and  distributed  to the  Grantee  until  the first
          business  day of the first year in which the Company is not  precluded
          from  deducting  the  associated  compensation  expense  under Section
          162(m) of the Code,  but only to the extent  such number of PARS would
          not be deductible until such time; further, provided, that the Grantee
          shall,  if applicable,  be credited with the Dividend  Equivalent with
          respect to such PARS.

              If the  Grantee's  employment  with the  Company is  involuntarily
terminated for Cause or the Grantee  voluntarily  terminates his employment with
the Company, the Grantee shall forfeit all PARS which have not yet become vested
as of the date of termination of employment.

     (b)  In the event of a Change in Control  (as  defined in the last  Section
          hereof), all PARS shall vest, be converted into shares of Common Stock
          and be immediately distributed to the Grantee.

          5. Equitable Adjustment.

The aggregate  number of shares of Common Stock subject to the PARS, and the $12
per  share  price  set forth in clause  3(b)  hereof,  shall be  proportionately
adjusted for any  increase or decrease in the number of issued  shares of Common
Stock resulting from a subdivision or  consolidation  of shares or other capital
adjustment,  or the payment of a stock dividend or other increase or decrease in
such shares,  effected without the receipt of  consideration by the Company,  or
other change in corporate or capital  structure.  The Committee  shall also make
the foregoing changes and any other changes, including changes in the classes of
securities  available,  to the  extent  reasonably  necessary  or  desirable  to
preserve the intended  benefits  under this  Agreement in the event of any other
reorganization, recapitalization, merger, consolidation, spin-off, extraordinary
dividend or other distribution or similar transaction involving the Company.

              6. Taxes.  The  Grantee  shall pay to the  Company  promptly  upon
request any taxes the Company  reasonably  determines it is required to withhold
under  applicable tax laws with respect to the PARS.  Such payment shall be made
as provided in Section IX(f) of the Plan.

              7. No Guarantee of Employment.  Nothing set forth herein or in the
Plan shall  confer upon the Grantee any right of  continued  employment  for any
period  by the  Company,  or shall  interfere  in any way with the  right of the
Company to terminate such employment.

              8. Notices.  Any notice required or permitted under this Agreement
shall be deemed given when delivered  personally,  or when deposited in a United
States Post Office, postage prepaid,  addressed, as appropriate,  to the Grantee
at the last address  specified in Grantee's  employment  records,  or such other
address as the  Grantee  may  designate  in writing  to the  Company,  or to the
Company,  Attention:  Corporate Secretary,  or such other address as the Company
may designate in writing to the Grantee.

              9.  Failure To Enforce Not a Waiver.  The failure of either  party
hereto to enforce at any time any provision of this Agreement shall in no way be
construed to be a waiver of such provision or of any other provision hereof.

              10.  Governing  Law.  This  Agreement  shall  be  governed  by and
construed according to the laws of the State of Delaware,  without regard to the
conflicts of laws provisions thereof.

              11.  Incorporation  of Plan.  The Plan is hereby  incorporated  by
reference and made a part of this Agreement, and this Agreement shall be subject
to the terms of the Plan, as the Plan may be amended from time to time, provided
that any such amendment of the Plan must be made in accordance with Section X of
the Plan.  The PARS granted herein  constitute  Awards within the meaning of the
Plan.

              12.  Counterparts.  This  Agreement may be executed in two or more
counterparts, each of which shall be an original but all of which together shall
represent one and the same agreement.

              13. Miscellaneous.  This Agreement cannot be changed or terminated
orally.  This  Agreement and the Plan contain the entire  agreement  between the
parties  relating to the subject matter hereof.  The section headings herein are
intended for reference only and shall not affect the interpretation hereof.

              14. Definitions. For purposes of this Agreement:

     (I) the term  "Beneficial  Owner"  (and  variants  thereof)  shall have the
     meaning given in Rule 13d-3 promulgated under the Exchange Act;

     (II) the term "Cause" shall mean (A) the willful and  continued  failure by
     the Grantee to substantially  perform the Grantee's duties with the Company
     (other than any such failure resulting from the Grantee's incapacity due to
     physical  or  mental  illness)  after  a  written  demand  for  substantial
     performance  is  delivered  to the  Grantee by the  Company,  which  demand
     specifically  identifies the manner in which the Company  believes that the
     Grantee has not  substantially  performed the Grantee's  duties, or (B) the
     willful  engaging  by the  Grantee in  conduct  which is  demonstrably  and
     materially  injurious  to the Company or its  subsidiaries,  monetarily  or
     otherwise. For purposes of clauses (A) and (B) of this definition,  no act,
     or failure to act, on the Grantee's part shall be deemed  "willful"  unless
     done,  or omitted to be done,  by the Grantee not in good faith and without
     the reasonable belief that the Grantee's act, or failure to act, was in the
     best interest of the Company;

     (III) the term "Change in Control" shall mean any of the following events:

                      (A)(i)  any Person (as  defined  in this  Section),  is or
              becomes the Beneficial Owner of 20% or more of either (x) the then
              outstanding  Common Stock of the Company (the "Outstanding  Common
              Stock") or (y) the combined  voting power of the then  outstanding
              securities entitled to vote generally in the election of directors
              of the Company (the "Total Voting Power"); excluding, however, the
              following:  (1)  any  acquisition  by  the  Company  or any of its
              affiliates or (2) any acquisition by any employee benefit plan (or
              related  trust)  sponsored or  maintained by the Company or any of
              its  affiliates  and  (ii)  Ciba  (as  defined  in  this  Section)
              beneficially  owns, in the aggregate,  a lesser  percentage of the
              Total Voting Power than such Person beneficially owns; or

                      (B) a change in the composition of the Board such that the
              individuals  who,  as of the  effective  date of  this  Agreement,
              constitute  the  Board  (such  individuals  shall  be  hereinafter
              referred to as the "Incumbent  Directors") cease for any reason to
              constitute  at least a majority of the Board;  provided,  however,
              for purposes of this definition, that any individual who becomes a
              director  subsequent to such effective date,  whose  election,  or
              nomination for election by the Company's stockholders, was made or
              approved pursuant to the Governance  Agreement (as defined in this
              Section)  or by a vote of at  least a  majority  of the  Incumbent
              Directors (or directors  whose election or nomination for election
              was  previously  so approved)  shall be considered a member of the
              Incumbent Board; but, provided,  further, that any such individual
              whose initial assumption of office occurs as a result of either an
              actual or threatened  election  contest (as such terms are used in
              Rule 14a-11 of Regulation 14A promulgated  under the Exchange Act)
              or other actual or threatened  solicitation of proxies or consents
              by or on behalf of a person or legal  entity  other than the Board
              shall not be considered a member of the Incumbent Board; or

                      (C) the approval by the  stockholders  of the Company of a
              reorganization,   merger  or   consolidation   or  sale  or  other
              disposition  of all or  substantially  all  of the  assets  of the
              Company  ("Corporate  Transaction");  excluding,  however,  such a
              Corporate  Transaction (i) pursuant to which all or  substantially
              all of the individuals and entities who are the beneficial owners,
              respectively,  of the  Outstanding  Common  Stock and Total Voting
              Power  immediately  prior  to  such  Corporate   Transaction  will
              beneficially   own,   directly  or  indirectly,   more  than  50%,
              respectively,  of the  outstanding  common  stock and the combined
              voting power of the then outstanding  securities  entitled to vote
              generally in the  election of  directors of the company  resulting
              from such Corporate Transaction (including,  without limitation, a
              corporation which as a result of such transaction owns the Company
              or  all  or  substantially  all of  the  Company's  assets  either
              directly or through one or more subsidiaries) in substantially the
              same  proportions  as their  ownership  immediately  prior to such
              Corporate  Transaction of the  Outstanding  Common Stock and Total
              Voting  Power,  as the case may be, or (ii) after  which no Person
              beneficially  owns a greater  percentage  of the  combined  voting
              power  of  the  then  outstanding   securities  entitled  to  vote
              generally in the election of  directors of such  corporation  than
              does Ciba; or

                                      164
<PAGE>

                      (D) Ciba shall  become the  Beneficial  Owner of more than
               57.5% of the Total Voting Power; or

                      (E) the approval by the  stockholders  of the Company of a

     (IX)  the  term  "Retirement"  shall  mean  termination  of  the  Grantee's
     employment,  other than by reason of death or Cause, either (A) at or after
