About OSS Capital LP

Founded in Nov. 2001 by Oscar S. Schafer
and Andrew J. Goffe

$ 2.2 billion under management

Long / Short investment partnership

Long-term investment approach

Hexcel stockholders since August 2005

Why Hexcel?

Great secular story

Significant barriers to entry

Emerging market and international growth

Margin expansion story-economies of scale

Stock inexpensive based on peer
performance

OSS Capital’s Goals

To enhance the relevant expertise of the Hexcel Board in
order to give Hexcel senior management more complete
resources to:

Enhance margins

Increase Hexcel’s competitive edge

Operate in a more efficient, global, and cost competitive
manner

To have all stockholders benefit from Hexcel’s increased
success as the pre-eminent player in composite material
manufacturing

The Key Issue

Hexcel’s margins are far below its competitors’:

Trailing Twelve Months, millions $

Toray Cytec Hexcel

Composite revenues 693.0 669.7 975.8

Composite operating inc. 154.0 132.3 142.8

% revenues 22.2% 19.8% 14.6%

Hexcel has not provided a plausible explanation for their inferior margin
performance

OSS Capital believes Hexcel does not fully understand its cost structure

Margins Consistently Fall Short

Operating Income As % Of Sales

The Key Issue, Magnified

An “apples to apples” margin comparison amplifies the
point:

Toray and Cytec allocate corporate overhead to their
composite subsidiaries, while Hexcel does not

Hexcel had approximately $50 million of unallocated expenses
in the trailing twelve months

Adjusted Composite Margins

Trailing Twelve Months, millions $

Toray Cytec Hexcel*

Composite revenues 693.0 669.7 975.8

Composite operating inc. 154.0 132.3 142.8

Less 80% of unall. exp. 39.0

Adjusted operating income 103.8

% revenues 22.2% 19.8% 10.6%

*As Hexcel’s composite business is approximately 80% of corporate revenues, assumes 80% pro-rata

allocation of corporate expenses to composite subsidiary

Adjusted Margin Shortfall Is Even
More Dramatic

Operating Income As % Of Sales *

*As Hexcel’s composite business is approximately 80% of corporate revenues, assumes 80% pro-rata allocation of

corporate expenses to composite subsidiary

Hexcel’s margins are consistently and
dramatically below their competitors’
margins.

Hexcel’s Analysis Is Misleading

In its April 2008 investor presentation, Hexcel presents misleading
statements about OSS Capital’s nominees:

Hexcel claims Ed Blechschmidt was the CEO of Gentiva for 30 months

Ed was the CEO of Olsten/Gentiva for 4 years

Hexcel claims no aerospace experience evident in Jake Hirsch’s background

At Textron, ~25% of the product overseen by Jake was for aerospace customers

Hexcel claims no public board experience evident in Tim Leuliette’s background

Tim has served on multiple public boards:

Operating Board, Siemens AG

Board of Directors member, Libby Owens Ford

Co-Chairman of the Board, Asahi Tec Corporation

Member of the Board & Chair of Restructuring Committee, Collins &
Aikman

Hexcel’s Analysis Is Misleading

In its April 2008 investor presentation, Hexcel presents a misleading
peer margin comparable analysis:

Hexcel includes multiple customers as its peer group

Most customers are not peers

Hexcel’s direct peers are Cytec and Toray

Cytec is a customer and peer

However, a comparison of total corporate margins is misleading

Cytec is a conglomerate and the proper approach is to compare Cytec’s
composite subsidiary with Hexcel’s composite subsidiary

Hexcel includes low margin composite “peers” Gurit and SGL carbon in its analysis

But Hexcel conveniently excludes Mitsubishi Rayon which has composite margins
north of 25%!

Hexcel’s Analysis Is Misleading

In its April 2008 investor presentation, Hexcel presents weak
explanations for sub-peer performance:

US health care costs

Foreign exchange

Investment for growth

Wage inflation

Raw material costs

Cost pressures are not unique; competitors face these same challenges and they do
not have the same scale as Hexcel!

No matter how the company is analyzed
and no matter what qualitative adjustments
or explanations are made, Hexcel’s margins
in the composite business are just too low.
Hexcel is underperforming and needs help.

The Value Gap

If Hexcel realized composite operating margins similar
to its peers, its composite operating income could be
$60+ million higher

Trailing Twelve Months, millions $

Toray Cytec Hexcel Hexcel Adj.

Composite revenues 693.0 669.7 975.8 975.8

Composite operating inc. 154.0 132.3 142.8 204.9

% revenues 22.2% 19.8% 14.6% 21.0%

Bridging The Value Gap

At $60 million in additional EBIT:

Current EV/EBIT multiple = 17.6x TTM EBIT

Additional equity value = $1.1 billion

Shares outstanding = 95.8 million

This represents a value gap of $11.50 per share.

The Aerospace Opportunity

In our view:

The secular aerospace boom presents a huge opportunity

Hexcel’s depressed profitability may hinder the company’s
ability to generate enough cash to fully support the
development of next generation composite aircraft

Hexcel should not be a second tier player on next
generation aircraft…they should be the dominant player!

Hexcel must focus intensely on developing an effective
global footprint with industry leading profitability and
execution

Why These Nominees?

The three business executives that OSS
Capital has nominated are committed to
these priorities and have the expertise to
help

Meet The Nominees

All three nominees possess successful manufacturing
backgrounds that are international in scope

Each has demonstrated success in operating in cost
competitive environments

Each enhances the Hexcel Board’s ability to move the
company to greater operating efficiency and profitability
