     This Amendment No. 12 to Schedule 13D relates to shares of Common Stock,
$0.01 par value per share (the "Shares"), of Integra LifeSciences Holdings
Corporation (the "Issuer"). This Amendment No. 12 supplementally amends the
initial statement on Schedule 13D, dated April 8, 1999, and all amendments
thereto (collectively, the "Initial Statement"), filed by the Reporting Persons.
This Amendment No. 12 is being filed by the Reporting Persons to report that the
Reporting Persons have ceased to own at least 5% of the issued and outstanding
Shares of the Issuer. Capitalized terms used but not defined herein shall have
the meanings ascribed to them in the Initial Statement. The Initial Statement is
supplementally amended as follows.

ITEM 2.           IDENTITY AND BACKGROUND.

     This Statement is being filed on behalf of each of the following persons
(collectively, the "Reporting Persons"):

                  i)       Quantum Industrial Partners LDC ("QIP");

                  ii)      QIH Management Investor, L.P. ("QIHMI");

                  iii)     QIH Management LLC ("QIH Management");

                  iv)      Soros Fund Management LLC ("SFM LLC") and

                  v)       Mr. George Soros ("Mr. Soros").

     This Statement relates to Shares held for the accounts of QIP and SFM
Domestic Investments LLC ("SFM Domestic Investments"). QIHMI is a minority
shareholder of, and is vested with investment discretion with respect to
portfolio assets held for the account of, QIP. The sole general partner of QIHMI
is QIH Management. SFM LLC is the sole managing member of QIH Management. Mr.
Soros is the Chairman of SFM LLC and the sole managing member of SFM Domestic
Investments.

     On December 27, 2002, Mr. Soros appealed a decision of the 11e Chambre du
Tribunal Correctionnel in Paris, France that fined him 2.2 million euros on
December 20, 2002 based on a finding of insider trading with respect to trading
in securities of Societe Generale in 1988. On March 24, 2005, the Paris Court of
Appeal affirmed the decision of the 11e Chambre du Tribunal Correctionnel. Mr.
Soros has filed an appeal at the French Cour de Cassation where the matter is
currently pending. Mr. Soros has elected to provide the foregoing information on
a voluntary basis.


ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

     According to information provided by the Issuer in its most recent
quarterly report on Form 10-Q, the number of Shares outstanding was 28,435,001
as of March 10, 2006.

     (a)  (i) As of April 3, 2006, each of QIP, QIHMI, QIH Management and SFM
          LLC may be deemed the beneficial owner of 1,073,181 Shares
          (approximately 3.8% of the total number of Shares outstanding).

          (ii) As of April 3, 2006, Mr. Soros may be deemed the beneficial owner
               of 1,356,596 Shares (approximately 4.8% of the total number of

     (b)  (i) As of April 3, 2006, each of QIP, QIHMI, QIH Management and SFM
          LLC (by virtue of the QIP Contract) and Mr. Soros (as a result of his
          position with SFM LLC) may be deemed to have the sole power to direct
          the voting and disposition of the 1,073,181 Shares held for the
          account of QIP.

          (ii) As of April 3, 2006, Mr. Soros in his capacity as the sole

               283,415 Shares held for the account of SFM Domestic Investments.

     (c)  As of April 3, 2006, except for the transactions listed on Annex A
          hereto, all of which were effected in the over-the-counter market in
          routine brokerage transactions, there have been no transactions with
          respect to the Shares since February 24, 2006 (the date of filing of
          the Reporting Persons' last statement on Schedule 13D) by any of the
          Reporting Persons.

     (d)  (i) The shareholders of QIP, including Quantum Industrial Holdings,
          Ltd., a British Virgin Islands international business company, have
          the right to participate in the receipt of dividends from, or proceeds
          from the sale of, the securities held for the account of QIP in
          accordance with their ownership interests in QIP.

          (ii) Certain members of SFM Domestic Investments have the right to
               participate in the receipt of dividends from, or proceeds from
               the sale of, the securities held for the account of SFM Domestic
               Investments.

     (e)  The Reporting Persons ceased to be the beneficial owners of more than
          5% of the issued and outstanding Shares on March 31, 2006.
