Kinetic Concepts, Inc. (NYSE:KCI), a global medical technology
company with leadership positions in advanced wound care and
therapeutic support systems, and LifeCell Corporation (NASDAQ:LIFC), a
leader in innovative tissue repair products for use in reconstructive,
urogynecologic and orthopedic surgical procedures, today announced
that they have signed a definitive agreement whereby KCI will acquire
LifeCell for $51.00 per share, or $1.7 billion in cash. The offer
represents an 18% premium over the closing price of LifeCell´s stock
on April 4, 2008, and a 26% premium over the 90-day volume weighted
average trading price. The boards of directors of both companies have
unanimously approved the transaction.

Following the completion of the transaction, LifeCell will operate
as a new global biosurgery division within KCI. Paul Thomas will
continue to lead the business as President of the division and will
join KCI´s Executive Committee. LifeCell´s management team and
corporate headquarters will continue to be located in Branchburg, New
Jersey. Based on existing KCI and LifeCell operations, the combined
companies are expected to generate revenue of approximately $2 billion
in 2008 and will employ more than 7,000 people.

"This is an exciting day for KCI," said Catherine Burzik,
President and Chief Executive Officer of KCI. "LifeCell is an
exceptional strategic fit for us. The acquisition of LifeCell provides
additional long-term growth opportunities, benefiting patients and
physicians and delivering sustained value to our shareholders. The
acquisition brings together two respected market leaders with
well-established best-in-class technologies. This combination allows
us to accelerate our strategy to increase KCI´s presence in the
operating room and will leverage our broad global market reach to
drive future growth of LifeCell´s products. The focus of the
integrated management team will be to bring to market unparalleled
therapeutic solutions for patients. I am confident that the combined
company will be a powerful force in delivering advanced therapies for
complex clinical situations. We admire the achievements of Paul Thomas
and his management team and look forward to welcoming LifeCell´s
world-class sales force and product development organizations to KCI
where they will play a crucial role in our future success."

"Our board of directors and management team believe this
transaction makes strategic sense for our company, offers a premium to
our stockholders and creates exciting opportunities for our
employees," said Paul Thomas, Chairman of the Board, President and
Chief Executive Officer of LifeCell. "We expect that the combination
of our leadership position in regenerative medicine and KCI´s
innovative therapeutic approach to wound healing will present
opportunities for both organizations to expand the markets we serve.
KCI´s global infrastructure will accelerate the penetration of
LifeCell products into international markets. We also believe KCI´s
experience and leadership position in advanced wound care will
facilitate the adoption of LifeCell´s innovative products into this
market. Together, we look forward to improving the lives of more
patients around the world."

Benefits of the Combination

-- Global Biosurgical Leadership: KCI will leverage its
infrastructure together with LifeCell´s products to create a
global medical technology leader with extensive experience
developing and commercializing best-in-class technologies and
clinically-proven products that achieve superior patient
outcomes.

-- Diversification of KCI Revenue Stream: The combination will
significantly diversify KCI´s future revenue. The company´s
advanced wound care platform has been its primary growth
driver and this acquisition represents the third major product
line for the company going forward. With revenue growth at 35%
in 2007, LifeCell would have represented approximately 11% of
combined revenue and provides a meaningful enhancement to the
growth trajectory that currently exists for KCI´s negative
pressure technology platform.

-- Increased Presence in the Operating Room and Acute Care
Setting: KCI continues to focus on the operating room and the
acute care setting both with its current product offerings and
with the development of novel products from its negative
pressure technology platform. Because LifeCell´s products are
primarily used in these care settings, this acquisition
accelerates KCI´s strategy and provides additional growth
opportunities for the combined company´s advanced products.

-- Combined Research and Development Capabilities: KCI and
LifeCell share similar philosophies for research and product
development. This acquisition will bring complementary
technical capabilities together to facilitate the timely
commercialization of high-value solutions to complex, unmet
clinical needs.

Financing and Structure

Under the terms of the merger agreement, a subsidiary of KCI will
commence a cash tender offer to acquire all outstanding shares of
LifeCell´s common stock at a price of $51.00 per share. KCI´s
obligation to consummate the tender offer is conditioned upon the
tender of at least a majority of the fully diluted LifeCell shares in
the offer, completion and funding of KCI´s financing arrangements
described below, and the satisfaction of regulatory and other
customary closing conditions. Following completion of the tender
offer, any remaining LifeCell shares would be acquired in a merger for
$51.00 per share.

KCI will use cash on hand and proceeds from a fully underwritten
debt financing from Bank of America and JPMorgan Chase Bank for the
acquisition. The bank financing includes syndicated term loans and a
revolving credit facility. Funding under the commitment is subject to
various conditions, including consummation of the tender offer in
accordance with the terms of the merger agreement and other conditions
similar to those applicable to the completion of the tender offer and
merger. As part of permanent financing and subject to market
conditions, KCI may access the equity-linked markets during 2008. KCI
and LifeCell had combined EBITDA in excess of $500 million in 2007 and
KCI expects to rapidly pay down debt.

KCI believes substantial opportunities exist to leverage adjacent
technologies and global infrastructure to drive meaningful revenue
synergies, and expects a reduction of certain general and
administrative expenses. Excluding the non-cash amortization of
intangibles, the transaction is expected to be initially dilutive to
cash earnings per share, becomes accretive to cash earnings per share
during 2009 and significantly accretive in 2010 and thereafter. On a
GAAP basis, the transaction is expected to become accretive to
earnings per share during 2010.

J.P. Morgan Securities Inc. acted as financial advisor to KCI and
Merrill Lynch & Co. acted as financial advisor to LifeCell. Skadden,
Arps, Slate, Meagher & Flom LLP and Lowenstein Sandler PC served as
legal advisors to KCI and LifeCell, respectively.

Ideal Strategic Partner

LifeCell´s best-selling product AlloDerm(R), used to repair
damaged tissue in hernias and breast reconstruction, generated $167
million in revenue for the company last year. LifeCell is the clear
leader in the rapidly growing biologics market. The addition of
LifeCell expands KCI´s offerings in the biosurgery and surgical suite
and provides access to new commercial and therapeutic opportunities.
By capitalizing on LifeCell´s strong relationships with acute care
operating physicians, KCI will have a platform upon which to launch
its next generation negative pressure-based products for the surgery
suite. Additionally, KCI plans to leverage its broad reach and global
competencies in market development, regulatory and reimbursement
functions to accelerate the global introduction of LifeCell´s
products.

LifeCell´s newest product, Strattice(TM), is the next generation
of regenerative products and has the potential to transform the tissue
regeneration industry. Easier to use, non-refrigerated, and available
in large sizes, Strattice(TM) will provide the company´s biosurgery
business opportunities for growth in other therapeutic areas and
international markets. Strattice(TM) received 510(k) FDA clearance in
June 2007 and is commercially available in the U.S.
