ITEM 3.02.  UNREGISTERED SALE OF EQUITY SECURITIES.

On October 20, 2006, Integra LifeSciences Holdings Corporation (the "Company")
issued $4,337,000 principal amount of its 2 1/2% Contingent Convertible
Subordinated Notes due 2008 (the "New Notes") in exchange for an equal amount of
validly tendered 2 1/2% Contingent Convertible Subordinated Notes due 2008 of
the Company that were initially issued in 2003 (the "Old Notes"). The Company
also made a one time cash payment to holders of Old Notes equal to $2.50 for
each $1,000 in principal amount of Old Notes tendered. The New Notes were issued
under the Indenture, dated September 29, 2006, by and among the Company and
Wells Fargo Bank, N.A., as trustee. On September 29, 2006, the Company issued
$115,205,000 principal amount of New Notes in exchange for an equal amount of
validly tendered Old Notes pursuant to an the Company's exchange offer that
expired on September 26, 2006, as was reported in the Company's Current Report
on Form 8-K filed on October 5, 2006.

The New Notes were offered solely to existing security holders of the Company
pursuant to an exemption from registration under Section 3(a)(9) of the
Securities Act of 1933, as amended. The Company did not pay or give, directly or
indirectly, any commission or other remuneration for soliciting such exchange.

The New Notes are convertible, under certain circumstances, into cash, and, if
applicable, shares of the Company's common stock, subject to the Company's right
to pay the share amount in additional cash. The initial conversion rate is
29.2847 shares of common stock per $1,000 principal amount of New Notes (subject
to adjustment in certain events), which is equivalent to an initial conversion
price of approximately $34.15 per share of common stock. The amount of cash and
common stock payable upon conversion will depend upon the value of the Company's
common stock over a 15 day period beginning on the third trading day after a
holder delivers a notice of conversion.

A description of the New Notes is set forth in Items 1.01 and 3.02 of the
Company's Current Report on Form 8-K filed on October 5, 2006, which is
available on the SEC's website (www.sec.gov) or the Company's website
(www.Integra-LS.com) and is incorporated by reference into this Item.
