                  Integra LifeSciences Reports Record Revenues
                    for the Fourth Quarter and Full Year 2005


Plainsboro, New Jersey, March 5, 2006 - Integra LifeSciences Holdings
Corporation (NASDAQ: IART) today reported its fourth quarter and full year 2005
revenues and earnings. Total revenues in the fourth quarter of 2005 were $73.0
million, reflecting an increase of $11.2 million, or 18%, over the fourth
quarter of 2004. Total revenues for the full year ended December 31, 2005
increased by $48.1 million to $277.9 million, a 21% increase over the prior
year.

We reported net income of $10.6 million, or $0.33 per diluted share, for the
fourth quarter of 2005, compared to net income of $9.8 million, or $0.30 per
diluted share in the fourth quarter of 2004. Net income for the year ended
December 31, 2005 was $37.2 million, or $1.15 per diluted share, compared to
$17.2 million, or $0.55 per diluted share for the year ended December 31, 2004.

When adjusted for certain restructuring related charges, net income for the
fourth quarter of 2005 was $12.1 million, or $0.37 per diluted share, and net
income for the full year 2005 was $42.1 million, or $1.29 per share. During the
fourth quarter, these charges included costs associated with the closing of
various facilities and related transitions, employee terminations, and other
integration and restructuring related costs. In 2004, net income, when adjusted
for certain charges set forth in the tables at the end of this release, was $9.9
million, or $0.30 per diluted share, in the fourth quarter, and $33.6 million,
or $1.03 per share, for the full year.

Both our reported net income and our adjusted net income benefited from a
reduction in our effective income tax rate, which decreased to 32.5% for the
full year. This decline was primarily related to our ability to recognize net
operating losses in a foreign jurisdiction due to the settlement of an income
tax audit, tax credits that became recognizable in the fourth quarter and
changes in the geographical mix of our pre-tax income.

"I am pleased with our performance in the fourth quarter and for the year," said
Stuart M. Essig, Integra's President and Chief Executive Officer. "During the
year, we achieved record revenues. We also completed the acquisition of the
Newdeal companies and added their international business to our existing sales
and distribution network. We substantially increased the headcount in both our
European sales and marketing departments and our domestic Reconstructive Surgery
sales force, and we launched several exciting new products for the treatment of
wounds and the surgical reconstruction of the foot and ankle.

"During the third quarter, we agreed to acquire the assets of the Radionics
Division of Tyco Healthcare Group LP The transaction, which closed on March 3,
2006, represents an ideal strategic fit for Integra. We expect the Radionics



acquisition to increase our revenues in 2006 by approximately 12 percent,
enhance our cash flow and profitability, and increase the proportion of our
business that comes from outside the United States.

"In 2005, we also accelerated product development, having launched new products
in dural regeneration, adhesion prevention, nerve repair, cranial reconstruction
and shunting for normal pressure hydrocephalus. Finally, we continued to cut
costs and improve margins through plant consolidations, closing manufacturing
sites in Texas and Germany, and restructuring our French manufacturing
facility."

Our revenues for the period were as follows:

Sales of our Reconstructive Surgery implant products grew particularly well.
Rapid growth in the NeuraGen(TM) Nerve Guide, the INTEGRA(TM) dermal repair
products and sales of Newdeal products for the foot and ankle accounted for most
of the increase in implant product revenues. INTEGRA(TM) dermal repair product
revenues increased approximately 86% over the fourth quarter of 2004, nerve
repair product revenues increased by 55%, and our Newdeal foot and ankle
products achieved record revenues of $4.8 million in the quarter. Our DuraGen(R)
family of duraplasty products continued to grow, although at slower rates than
in recent years. Sales of the DuraGen Plus(TM) and Suturable DuraGen(TM) Dural
Regeneration products led the growth in sales of this group of products. Sales
of the NPH(TM) Low Flow Hydrocephalus Valve also contributed to the growth in
implant product revenues for the quarter.

Monitoring revenues grew at 4% over the fourth quarter of 2004, an improvement
over the last several quarters. Increased sales of our intracranial monitoring
products, drainage systems, and cranial access kits accounted for the increase
in monitoring product revenues. Sales of our LICOX(R) Brain Oxygen Monitoring
System product line increased approximately 39% over the prior-year period. We
have developed a new targeted account sales and marketing strategy for products
in this category, and we expect that it will contribute to improvements in the
performance of our monitoring products in future periods.

Increased revenues of the Absorbable Collagen Sponge that we supply for use in
Medtronic's INFUSE(TM) bone graft product led the growth in revenues of our
private-label products. In the fourth quarter of 2005, we recognized an
additional $1.3 million of royalty revenue related to a change in the manner we
use to estimate royalties based on Medtronic's sales of its INFUSE(TM) bone
graft product.

Excluding recently acquired product lines and changes in foreign currency
exchange rates, fourth quarter 2005 revenues increased by $7.2 million, or 12%,
over the prior-year period. Changes in foreign currency exchange rates had a
negative impact of $0.9 million on our quarterly year-over-year revenue growth.

Gross margin on total revenues in the fourth quarter of 2005 was 61%. Although
we had strong growth in higher gross margin products, we incurred approximately
$1.3 million in restructuring and manufacturing transfer costs. These charges
reduced our gross margin by approximately 2%.





Research and development expense decreased from $3.6 million in the fourth
quarter of 2004 to $2.7 million in the current period.

Selling, general and administrative expense increased by $5.4 million to $25.7
million in the fourth quarter of 2005, increasing as a percentage of revenue to
35% from 33% in the prior-year period. This increase was primarily attributable
to expenses of acquired operations, as well as the further development of our
European infrastructure. The increase included approximately $752,000 of charges
associated with the closing of various facilities and related transitions,
employee terminations and other acquisition, integration and restructuring
related costs. These charges increased selling, general and administrative
expense by 1% of revenues.

We reported net interest income of $16,000 in the fourth quarter of 2005
compared to $95,000 in the prior-year period.

The Company generated $15.1 million in cash flows from operations in the fourth
quarter of 2005. We repurchased 900,000 shares of our common stock in the
quarter at an average price of $35.21 per share for an aggregate purchase price
of approximately $31.7 million. Our cash and investments totaled $143 million at
December 31, 2005.

In December 2005, we established a $200 million, five-year, senior secured
revolving credit facility. This new line of credit provides us with increased
financial flexibility and access to capital to support the Company's continued
growth. The credit facility currently allows for revolving credit borrowings in
a principal amount of up to $200 million, which can be increased to $250 million
should additional financing be required in the future. We plan to utilize the
credit facility for working capital, capital expenditures, share repurchases,
acquisitions and other general corporate purposes.

We are updating our expectations for total revenues, gross margin and earnings
per share for 2006 and providing our initial guidance for 2007. Our expectations
for 2006 and 2007 financial performance include the impact of the just closed
Radionics acquisition, but, in accordance with our usual practice, do not
include the impact of acquisitions or other strategic corporate transactions
that have not yet closed.

We expect total revenues in 2006 to be between $365 million and $380 million,
and total revenues in 2007 to be between $420 million and $440 million. We
expect consolidated gross margin to increase to 65% and 66% of total revenues in
2006 and 2007, respectively, including the impact of purchase accounting related
to the Radionics acquisition and share based compensation costs.

We expect that unfavorable foreign currency exchange rate movements will have a
negative impact on our revenue growth rates in 2006. If foreign currency
exchange rates hold at current levels, our forward looking guidance anticipates
an unfavorable impact on net sales of approximately 2% in the first quarter of
2006 and an unfavorable impact on net sales of approximately 1% for the full
year of 2006.

Our guidance includes both the direct impact of the Radionics acquisition and
our assumption that our sales force will, in some situations, sell the CUSA
EXcel(TM) ultrasonic aspiration system in lieu of our existing ultrasonic
aspirator products.

The Company may incur significant costs this year in connection with
restructuring and integration activities, including purchase accounting charges
related to the Radionics acquisition. We currently expect these charges to be
approximately $2.5 million in 2006.

The Company also expects the impact of estimated share based compensation
expense for 2006 and 2007 to be in the range of $0.27 to $0.29 per diluted
share.



Earnings per diluted share are expected to be within a range of $1.69 to $1.76
in 2006, excluding restructuring and integration charges and the impact of
estimated share based compensation expense. Earnings per diluted share are
expected to be within a range of $1.95 to $2.10 in 2007, excluding the impact of
estimated share based compensation expense. On a GAAP reported basis, we expect
earnings per diluted share to be within a range of $1.35 to $1.44 in 2006 and
within a range of $1.66 to $1.83 in 2007.

Our guidance for the first quarter of 2006 is for total revenues in the range of
$78 million to $82 million including a contribution of approximately $4 million
from the Radionics acquisition, and adjusted earnings per diluted share of $0.34
to $0.36, excluding restructuring and integration charges of $0.02 and the
impact of estimated share based compensation expense of $0.07. On a GAAP
reported basis, we expect earnings per diluted share to be within a range of
$0.25 to $0.27 in the first quarter of 2006.

Our Board of Directors has authorized us to repurchase shares of our common
stock for an aggregate purchase price not to exceed $50 million through December
31, 2006. We may repurchase shares under this program either in the open market
or in privately negotiated transactions.

We have scheduled a conference call for 9:00 am EST tomorrow, March 6, 2006, to
discuss the financial results for the fourth quarter of 2005 and forward-looking
financial guidance. The call is open to all listeners and will be followed by a

This news release contains forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. Forward-looking statements
include, but are not limited to, statements concerning future financial
performance, including projections for revenues, gross margins, earnings per
share and cash flows. Such forward-looking statements involve risks and
uncertainties that could cause actual results to differ materially from
predicted or expected results. Among other things, our ability to maintain
relationships with customers of acquired entities, physicians' willingness to
adopt our recently launched and planned products and our ability to secure
regulatory approval for products in development may adversely affect our future
product revenues; our ability to increase sales and product volumes may
adversely affect our future gross margins; our ability to integrate acquired
businesses (including the Radionics business), increase product sales and gross
margins, and control non-product costs may affect our earnings per share; our
future net income results and our ability to effectively manage working capital
may affect our future cash flows; and our ability to complete the restructuring
and integration activities may affect our operating income. In addition, the
economic, competitive, governmental, technological and other factors identified
under the heading "Factors That May Affect Our Future Performance" included in
the Business section of Integra's Annual Report on Form 10-K for the year ended
December 31, 2004 and information contained in subsequent filings with the
Securities and Exchange Commission could affect actual results.

Regulation G, "Conditions for Use of Non-GAAP Financial Measures," and other
provisions of the Securities Exchange Act of 1934, as amended, define and
prescribe the conditions for the use of certain non-GAAP financial information.



In this news release, we provide "adjusted net income" and "adjusted earnings
per share", which exclude charges related to acquisitions, integrations and
restructurings, and "growth in revenues excluding recently acquired product
lines and changes in foreign currency exchange rates", all of which are non-GAAP
financial measures. We believe that, given our on-going, active strategy of
seeking acquisitions and our current focus on rationalizing our existing
manufacturing and distribution infrastructure, and the extent of changes in
foreign currency exchange rates, net income and earnings per share adjusted to
exclude costs related to acquisitions, integrations and restructurings, and
growth in revenues excluding recently acquired product lines and changes in
foreign currency exchange rates, are useful additional bases to measure the
performance of our business operations, both in this quarter and in future
periods. In addition, excluding future share based compensation charges from our
projected adjusted earnings per share allows for comparability of our guidance
to historical periods. A reconciliation of these non-GAAP financial measures to
the most comparable GAAP measures is provided in the tables of financial
information contained at the end of this news release.

Non-GAAP financial measures should not be relied upon to the exclusion of GAAP
financial measures. Management believes that these non-GAAP financial measures
are important supplemental information to investors which reflect an additional
way of viewing aspects of our operations that, when viewed with our GAAP results
and the accompanying reconciliations, provides a more complete understanding of
factors and trends affecting our ongoing business and operations. Management
strongly encourages investors to review our financial statements and filed
reports in their entirety and to not rely on any single financial measure.
Because non-GAAP financial measures are not standardized, it may not be possible
to compare these financial measures with other companies' non-GAAP financial
measures having the same or similar names.
