            Integra LifeSciences Reports Record Pre-Tax Earnings and
                      Revenues for the First Quarter 2003

                 Cash Flows from Operations Totaled $8.8 Million

Plainsboro,  NJ /April 25, 2003 / -- Integra  LifeSciences  Holdings Corporation
(Nasdaq:  IART) today  reported net income of $5.4 million,  or $0.18 per share,
for the first  quarter of 2003,  as compared to net income of $4.1  million,  or
$0.13 per share, in the first quarter of 2002.

Total  revenues in the first  quarter of 2003  increased  $10.9 million to $36.8
million,  a 42%  increase  over  total  revenues  in the first  quarter of 2002.
Revenues  from product lines  acquired  since the beginning of the first quarter
2002  accounted  for $6.2 million of the increase in total  revenues.  Excluding
revenues attributable to product lines acquired since the beginning of the first
quarter of 2002, first quarter 2003 product revenues  increased by $4.4 million,
or 18%, over the prior year period.

Pre-tax  earnings for the period were $8.6 million,  an increase of 36% over the
first quarter of 2002.

"I am very pleased with our record revenues and pre-tax  earnings this quarter,"
said Stuart M. Essig,  Integra's President and Chief Executive Officer. "We also
completed two significant  transactions that position us for further growth. Our
acquisition of JARIT(R) Surgical Instruments provides us with an established and
respected  name in general  surgery  instruments  and broadens our  distribution
channels  and  customer   base.  We  also  issued  $105  million  of  contingent
convertible  subordinated  notes,  which  significantly  increased our financial
flexibility."

Following our integration of several diverse businesses we acquired,  in 2003 we
began to manage our business and review financial results on an aggregate basis,
instead of through different  operating  segments.  Now, integrated teams manage
functions such as marketing,  manufacturing,  research, sales and administration
for the entire Company. Accordingly, we now report our financial results under a
single operating segment--the  development,  manufacturing,  and distribution of
medical  devices.  For  comparative  purposes,  we have revised our prior period
results to reflect this change.


Revenues are now segregated into the following categories:

                                         Quarter Ended March 31,
                                             2003       2002    % Increase
                                          --------    -------   ----------
Product revenue:
Neuromonitoring products                   $10,532    $ 8,582        23%
Operating room products                     12,588      7,872        60%
Instruments                                  6,247      3,823        63%
Private label products                       5,763      4,242        36%
                                          --------   --------   ----------
   Total product revenue                   $35,130    $24,519        43%
Other revenues                               1,650      1,397        18%
                                          --------   --------   ----------
   Total revenue                           $36,780    $25,916        42%

Product revenues for the first quarter of 2003 increased $10.6 million,  or 43%,
over the first quarter of 2002 to $35.1 million. Increased sales of drainage and
cranial  access kits  provided most of the growth in  neuromonitoring  products.
Revenues from  neurosurgical  shunt products  acquired in 2002 and the continued
growth in sales of the DuraGen(R) Dural Graft Matrix and the NeuraGen(TM)  Nerve
Guide products drove the increase in operating room product  revenues.  Sales of
the  Padgett(R) and JARIT  surgical  instrument  lines acquired in 2002 and 2003
accounted  for most of the year  over  year  increase  in  instrument  revenues.
Revenues from acquired product lines and increased  revenue from the VitaCuff(R)
device and the Absorbable Collagen Sponge used in Medtronic's bone graft product
contributed significantly to the increase in private label product revenues. The
growth in other revenue is  attributable  to an increase in product  development
revenue offset in part by a decrease in distribution and license fees.

Acquisitions and recent product launches continue to contribute significantly to
the  Company's  revenue  growth.  Product  revenues in the first quarter of 2003
included the following amounts in sales of acquired product lines:

                          Revenue from product     Total revenue
                           lines acquired in       from acquired       Total
                           2003          2002      product lines      revenue
                          ------        ------     --------------     -------
Neuromonitoring products  $  --         $  922          $  922        $10,532
Operating room products      --          2,346           2,346         12,588
Instruments                1,132         1,056           2,188          6,247
Private label products       --            719             719          5,763

Reported gross margin on product  revenues in the first quarter of 2003 remained
consistent  with  the  first  quarter  of 2002 at 61% of  product  revenues  and
included  the  negative  impact of $346,000  of  inventory  fair value  purchase
accounting adjustments.

Sales and  marketing  expense  increased  by $2.0 million to $7.6 million in the
first  quarter of 2003, a slight  decrease as a percentage  of product  revenues
from the prior year period. General and administrative expense increased by $1.9
million over the first quarter of 2002 to $4.8 million, primarily as a result of
costs incurred in operating the businesses acquired in 2002 and 2003.

The Company  generated  $8.8 million in cash flows from  operations in the first
quarter  of 2003,  as  compared  to $5.5  million  in the  prior  year  quarter.
Operating cash flows improved in the first quarter of 2003 primarily as a result
of higher net income.



The Company's net interest  income  decreased by $0.2 million to $0.8 million in
the first  quarter of 2003,  primarily  as a result of a  continued  decrease in
interest rates.

The $0.9  million  increase in income tax  expense in the first  quarter of 2003
reflects a slight  increase  in the  effective  tax rate  projected  for 2003 to
36.5%,  as compared to the 35% effective  rate reported for the first quarter of
2002. The Company  expects to report an effective tax rate of 36.5% for the full
year 2003.

The Company used approximately  $42.4 million of cash to purchase JARIT Surgical
Instruments  on March 17,  2003.  On March 31,  2003,  the Company  received net
proceeds  of  $101.9  million  from the  sale of  $105.0  million  of its 2 1/2%
Contingent  Convertible  Subordinated Notes due March 15, 2008. The Company used
approximately  $35.3  million  of the  proceeds  from the  sale of the  notes to
repurchase 1.5 million shares of its common stock.

The Company's  cash and  investments  totaled $170 million at March 31, 2003. On
April 11, 2003 the Company  received $14.5 million in net proceeds from the sale
of an additional $15.0 million of notes.

Integra is revising its expectations for revenues, gross margin and earnings for
2003 and 2004.  We expect  total  revenues to increase to between  $168 and $171
million in 2003 and $196 and $206  million in 2004.  Gross margin is expected to
be 60% and 62% of  product  revenues  in 2003 and 2004.  Excluding  a  potential
in-process  research and development  charge related to a $1.5 million milestone
payment that may become due in connection with a product development  agreement,
we expect our  earnings to be within a range of $0.80 to $0.82 per share in 2003
and $1.05 to $1.10 per share in 2004.  The  Company's  guidance  for the  second
quarter of 2003 is for total revenues in the range of $42.5 to $43.5 million and
earnings per share of $0.18. The Company's second quarter guidance  includes the
negative  impact of  approximately  $700,000 of  inventory  fair value  purchase
accounting  adjustments from the JARIT and Padgett  acquisitions.  In accordance
with the Company's usual practices,  management's expectations for 2003 and 2004
financial  performance  do not  include  the  impact  of  acquisitions  or other
strategic corporate transactions that have not yet closed.

The Company  has  scheduled a  conference  call for 9:00 am ET today,  April 25,
2003,  to discuss the  financial  results  for the first  quarter of 2003 and to
further discuss its forward-looking  financial guidance. The call is open to all
