Mr. David Berges
Chairman and Chief Executive Officer
Hexcel Corporation
Two Stamford Plaza

Stamford, CT 06901

Dear David:

Thank you for  visiting  our  office  on April  9th.  The  answers  we  received
reinforced  our views  outlined  in our  letter  dated  March 9, 2007  (which is
attached) that (1) Hexcel is under-earning, (2) management is not addressing the
shortfall  in  earnings,  and (3)  the  shareholders  are  suffering  from  this
situation.  We think that Hexcel would benefit from an independent review of its
prospects and strategy with a view toward taking action to maximize  shareholder
value.  To accomplish  this, we request a committee of independent  directors be
formed and that the committee retain an independent investment bank to advise as
to how shareholder value can best be maximized.

We are filing a schedule 13D with the Securities and Exchange Commission
disclosing our ownership of 4,810,900 shares of Hexcel stock. This letter and
our earlier letter will be attached to that filing.

We look forward to the Board's response.

Sincerely,

----------------------       -----------------------       ---------------------
