This Amendment No. 5 ("Amendment No. 5") amends and supplements the statement on
Schedule 13D initially filed on November 14, 2005 (the "Original Filing" and,
as amended, the "Schedule 13D") by Stuart M. Essig with respect to Common Stock,
$.01 par value (the "common stock"), of Integra LifeSciences Holdings
Corporation (the "Company").  Capitalized terms used and not defined in this
Amendment No. 5 have the meanings set forth in the Schedule 13D.

Item 5.           Interest in Securities of Issuer

                  Item 5 of the Schedule 13D is hereby amended and restated in
                  its entirety as follows:

                  (a) Aggregate number and percentage of class beneficially
                      owned:

                           As of January 4, 2008, Mr. Essig may be deemed to be
                           the beneficial owner of 2,648,022 shares of common
                           stock. This ownership consists of the following:

                           (i) 1,254,728 shares of common stock held directly by
                           Mr. Essig, including 500,000 shares of common stock
                           issuable on March 4, 2008; and

                           (ii) 1,393,294 shares of common stock underlying
                           options to purchase common stock (of which options to
                           purchase 851,106 shares of common stock are
                           exercisable as of, or within 60 days of, January 4,
                           2008).

                           Based on calculations made in accordance with Rule
                           13d-3(d), Mr. Essig may be deemed the beneficial
                           owner of 10.0% of the outstanding shares of common
                           stock. This calculation is based on 26,363,053 shares
                           of common stock outstanding as of November 5, 2007.

                           The above calculations include 542,188 shares of
                           common stock underlying options held by Mr. Essig
                           that are not exercisable as of, or within 60 days of,
                           January 4, 2008. Mr. Essig disclaims beneficial
                           ownership of these shares. Excluding these shares,
                           Mr. Essig would be deemed the beneficial owner of
                           2,105,834 shares of common stock (or 7.9% of the
                           outstanding shares of common stock).

                  (b) Voting and Dispositive Power:

                           Mr. Essig has sole voting and dispositive power over
                           2,648,022 shares that may be deemed to be
                           beneficially owned by him as of January 4, 2008. This
                           consists of the following (i) the 1,254,728 shares of
                           common stock held directly by Mr. Essig including
                           500,000 shares of common stock issuable on March 4,
                           2008 and (ii) 1,393,294 shares of common stock
                           underlying options to purchase common stock, of which
                           Mr. Essig disclaims beneficial ownership with respect
                           to 542,188 shares of common stock as set forth in
                           Item 5(a).

                  (c)      Transactions within the past 60 days: On December 18,
                           2007, the Company granted Mr. Essig an option to
                           purchase 200,000 shares of common stock. Of the
                           200,000 shares of common stock subject to the option
                           grant, 50,000 shares are exercisable on December 18,
                           2008, and the remaining 150,000 shares vest each
                           month in equal installments over the next thirty six
                           months.



                  (d)      Right to Direct the Receipt of Dividends: Not
                           applicable.

                  (e)      Last Date on Which Reporting Person Ceased to be a 5%
                           Holder: Not Applicable.

                  Respect to Securities of the Issuer.

                  Not applicable.
