Dear Sandy:

As one of the largest investors in Hexcel, we have attempted to work with you
over the past year to upgrade the expertise of Hexcel's Board. This past
December, you met with three Board nominees that were proposed by OSS Capital.
After over two months, you responded to us on February 19th indicating that
Hexcel would be willing to nominate only ONE of our candidates to the Board.
This is not acceptable and we responded to you as such later that day.

The Hexcel Board needs the help of world-class executives who have operated
cost-competitive, industrial businesses in both domestic and overseas
environments. The people we nominated possess the skills to help Hexcel better
execute in its cost-cutting initiatives, the growth of its international
footprint, and its core industrial manufacturing capabilities. We believe their
experience can be instrumental in moving the margins of Hexcel to a more
industry-appropriate level, which should result in a substantially higher stock
price.

With the record date for Hexcel's 2008 Annual Meeting of Stockholders
approaching, OSS Capital has no alternative but to go directly to stockholders
with its three nominees. As such, we will be filing preliminary proxy materials
with the SEC this week to support the election of the three candidates to the
Hexcel Board.


Sincerely,



/s/ Oscar S. Schafer    /s/ Andrew J. Goffe     /s/    Peter J. Grondin
