ITEM 5.  OTHER EVENTS.

On December 22, 2000, Integra LifeSciences Holdings Corporation entered into an
Amended and Restated Employment Agreement with Stuart M. Essig, Integra's
current President and Chief Executive Officer, extending the term of Mr. Essig's
employment with Integra as its President and Chief Executive Officer through
December 31, 2005. The Amended Employment Agreement supersedes Mr. Essig's prior
employment agreement with Integra.

Under the Amended Employment Agreement, Integra will pay Mr. Essig an annual
base salary of $325,000 for 2001 and $400,000 for 2002. For each subsequent year
that he is employed, Mr. Essig's annual base salary will be $400,000 plus such
increases, if any, as may be established by Integra's Board of Directors. Mr.
Essig is also eligible to receive a performance bonus of up to fifty percent
(50%) of his base salary, based upon the satisfaction of certain performance
goals established by Integra's Board of Directors. Mr. Essig is also entitled to
life insurance equal to the lesser of (a) a $3,000,000 four-year minimum
renewable term life insurance policy and (b) the four-year minimum renewable
term life policy purchasable by Integra by paying premium payments of $5,000 per
year for such policy. At the request of Mr. Essig, Integra will disburse a loan
to Mr. Essig in the amount of up to $500,000 subject to certain conditions. Mr.
Essig is also entitled to participate in Integra's medical, disability, pension
and other employee benefit plans and programs maintained from time to time by
Integra for the benefit of its senior executives. The Amended Employment
Agreement is for an initial term through December 31, 2005 and shall
automatically extend on December 31, 2005 and on each subsequent one-year
anniversary thereof for one year unless Integra or Mr. Essig provides written
notice of termination at least six months prior to the expiration of the
then-current term.

The Amended Employment Agreement further provides that Integra generally will
reimburse, or "gross-up," Mr. Essig on an after-tax basis for any excise tax
liability he may incur by reason of any "excess parachute payments" he receives
from Integra. Section 280G of the Internal Revenue Code of 1986, as amended,
provides that if payments of compensation that are contingent on a change in
control exceed three times an employee's "base amount" (his average annual
compensation during certain prior years), they will constitute "parachute
payments," and the excess of such parachute payments over such base amount
generally will constitute "excess parachute payments." Such excess parachute
payments are nondeductible by the employer and are subject to a 20% excise tax
payable by the employee.

In connection with the extension of the term of Mr. Essig's employment pursuant
to the Amended Employment Agreement, Integra granted Mr. Essig (i) a
non-qualified stock option to purchase 250,000 shares of Integra common stock
under Integra's 1999 Stock Option Plan, (ii) a non-qualified stock option to
purchase 250,000 shares of Integra common stock under Integra's 2000 Equity
Incentive Plan and (iii) 1,250,000 "Restricted Units" under Integra's 2000
Equity Incentive Plan. Each stock option (each, an "Option") expires on December
21, 2010 and has an exercise price equal to $11.00 per share (the closing price
of Integra's common stock on The Nasdaq National Market on December 21, 2000).
Assuming the continuation of Mr. Essig's employment with Integra, each Option
will vest and become exercisable with respect to 62,500 shares on December 22,
2002 and thereafter with respect to 1/36th of the remaining shares on the first
business day of each following month. In the event of a (i) "change in control"
of Integra (as defined in the Amended Employment Agreement) or (ii) the
termination of Mr. Essig's employment with Integra (a) by Integra without
"cause" (as defined in the Amended Employment Agreement) or (b) by Mr. Essig for
"good reasons" (as defined in the Amended Employment Agreement), the Options
shall vest and become exercisable immediately. The Option granted pursuant to
Integra's 1999 Stock Option Plan may be transferred by Mr. Essig to members of
his immediate family, to trusts established for the benefit of his immediate
family or to partnerships or limited liability companies of which the partners
or members are members of his immediate family. Otherwise, the Options may not
be transferred by Mr. Essig other than by will or by the laws of descent and
distribution.


                                     -2-




Under a Restricted Units Agreement, Integra issued to Mr. Essig a fully vested
equity-based signing award bonus in the form of 1,250,000 restricted units (the
"Restricted Units"). Each Restricted Unit represents the right to receive one
share of the Integra's common stock. The shares of Integra's common stock
underlying the Restricted Units ("Unit Shares") shall be delivered to Mr. Essig
on January 1, 2006 if Mr. Essig is employed by Integra on December 31, 2005 or
on such earlier date as a change in control of Integra occurs; provided,
however, that Mr. Essig has the right to defer the delivery of the Unit Shares
on as many occasions as Mr. Essig determines from time to time through, but not
beyond, June 30, 2025. The Unit Shares may be delivered to Mr. Essig prior to
January 1, 2006 in the event of a termination of Mr. Essig's employment with
Integra other than (a) for cause or (b) due to his voluntary departure (other
than for good reasons or due to disability). If, prior to December 31, 2005 and
prior to a change of control of Integra, (i) Mr. Essig's employment with Integra
is terminated for cause or (ii) Mr. Essig voluntarily leaves his employment with
Integra (other than for good reasons or due to disability), the Unit Shares will
be distributed to Mr. Essig on January 1, 2010.

Integra has also granted Mr. Essig registration rights requiring Integra to file
a "shelf" registration statement at Mr. Essig's request that will provide for
the registration and sale on a continuous or delayed basis of the shares of
Integra common stock underlying the Options and the Restricted Units.

                    INTEGRA LIFESCIENCES HOLDINGS CORPORATION


                        STOCK OPTION GRANT AND AGREEMENT
                                   PURSUANT TO
                             1999 STOCK OPTION PLAN


         STOCK OPTION GRANT AND AGREEMENT made as of the 22nd day of December,
2000 (the "Grant Date"), between INTEGRA LIFESCIENCES HOLDINGS CORPORATION, a
Delaware corporation (the "Company"), and STUART M. ESSIG, an employee of the
Company (the "Employee").

         WHEREAS, the Company desires to afford the Employee an opportunity to
purchase shares of common stock of the Company ("Common Stock"), par value $.01
per share, as hereinafter provided, under the Integra LifeSciences Holdings
Corporation 1999 Stock Option Plan (the "Plan"), a copy of which is attached.

         NOW THEREFORE, in consideration of the mutual covenants hereinafter set
forth and for other good and valuable consideration the legal sufficiency of
which is hereby acknowledged, the parties hereto, intending to be legally bound
hereby, agree as follows:

         1. GRANT OF OPTION. Pursuant to the Amended and Restated Employment
Agreement by and between the Employee and the Company dated as of December 22,
2000 (the "Employment Agreement"), the Company hereby grants to the Employee a
non-qualified stock option (the "Option") to purchase all or any part of an
aggregate of 250,000 shares of Common Stock.

         2. PURCHASE PRICE. The purchase price per share of the shares of Common
Stock covered by the Option shall be $11.00. It is the determination of the
Company's Stock Option Committee (the "Committee") that on the Grant Date the
purchase price per share was not less than the greater of one hundred percent
(100%) of the fair market value of the Common Stock, or the par value thereof.

         3. TERM. Unless earlier terminated pursuant to any provision of this
Stock Option Grant and Agreement or the Employment Agreement, this Option shall
expire on December 21, 2010 (the "Expiration Date"), which date is not more than
ten (10) years from the Grant Date. Notwithstanding anything herein to the
contrary, this Option shall not be exercisable after the Expiration Date.

         4. EXERCISE OF OPTION. The Committee, using its authority and
discretion under Sections 2 and 8(d) of the Plan to set the terms of Options
granted under the Plan, has determined that this Option, subject to law and
regulation, shall vest and become exercisable in such installments and on such
dates, as follows:

                  This Option shall vest and become exercisable with respect to
                  62,500 shares on the second anniversary of the date hereof.
                  Thereafter, this Option shall vest and become exercisable with
                  respect to 1/36th of the remaining shares on the first
                  business day of each following month. Except as provided in
                  Section 8(i) hereof, this Option shall vest and become
                  exercisable in its entirety, and shall remain exercisable
                  until the Expiration Date, (i) upon the occurrence of a
                  "Change in Control" (as defined in the Employment Agreement),
                  or (ii) upon the receipt of a BONA FIDE two-tier tender offer
                  with respect to the outstanding shares of Common Stock.

                  The portion of the Option that becomes exercisable in
accordance with the foregoing shall




remain exercisable, subject to the provisions contained in this Stock Option
Grant and Agreement, until the expiration of the term of this Option as set
forth in Paragraph 3 or until other termination of the Option as set forth in
this Stock Option Grant and Agreement.

         5. METHOD OF EXERCISING OPTION. Subject to the terms and conditions of
this Stock Option Grant and Agreement, the Option may be exercised in whole or
in part by written notice to the Company, at its principal office, which is
located at 311C Enterprise Drive, Plainsboro, New Jersey 08536. Such notice
shall state the election to exercise the Option, and the number of shares with
respect to which it is being exercised, shall be signed by the person or persons
so exercising the Option; shall, unless the Company otherwise notifies the
Employee, be accompanied by the investment certificate referred to in Paragraph
6; and shall be accompanied by payment of the full Option price of such shares.

                  The Option price shall be paid to the Company in: (i) cash;
(ii) cash equivalent; (iii) Common Stock of the Company, in accordance with
Section 8(d)(2)(B)(i) of the Plan (as in effect on the date of this Stock Option
Grant and Agreement); (iv) any combination of (i)-(iii); or (v) by delivering a
properly executed notice of exercise of the Option in accordance with Section
8(d)(2)(B)(iv) of the Plan (as in effect on the date of this Stock Option Grant
and Agreement).

                  Upon receipt of such notice and payment, the Company, as
promptly as practicable, shall deliver or cause to be delivered a certificate or
certificates representing the shares with respect to which the Option is so
exercised. Such certificate(s) shall be registered in the name of the person or
persons so exercising the Option (or, if the Option is exercised by the Employee
and if the Employee so requests in the notice exercising the Option, shall be
registered in the name of the Employee and the Employee's spouse, jointly, with
right of survivorship) and shall be delivered as provided above to or upon the
written order of the person or persons exercising the Option. In the event the
Option is exercised by any person or persons after the legal disability or death
of the Employee, such notice shall be accompanied by appropriate proof of the
right of such person or persons to exercise the Option. All shares that are
purchased upon the exercise of the Option as provided herein shall be fully paid
and not assessable by the Company.

         6. SHARES TO BE PURCHASED FOR INVESTMENT. Unless the Company has
theretofore notified the Employee that a registration statement covering the
shares to be acquired upon the exercise of the Option has become effective under
the Securities Act of 1933 and the Company has not thereafter notified the
Employee that such registration statement is no longer effective, it shall be a
condition to any exercise of this Option that the shares acquired upon such
exercise be acquired for investment and not with a view to distribution, and the
person effecting such exercise shall submit to the Company a certificate of such
investment intent, together with such other evidence supporting the same as the
Company may request. Notwithstanding the foregoing, upon the written request of
Employee, the Company shall provide the Employee with a shelf registration
pursuant to a registration statement subject to the terms set forth in EXHIBIT B
to the Employment Agreement. The Company shall be entitled to delay the
transferability of the shares issued upon any such exercise to the extent
necessary to avoid a risk of violation of the Securities Act of 1933 (or of any
rules or regulations promulgated thereunder) or of any state laws or
regulations. Such restrictions may, at the option of the Company, be noted or
set forth in full on the share certificates. If any law or regulation requires
the Company to take any additional action regarding the Common Stock before the
Company issues certificates for the Common Stock subject to this Option or
before such Common Stock may be transferred by the Employee, the Company shall
use its commercially reasonable best efforts to resolve such problem.

         7. TRANSFERABILITY. This Option is not assignable or transferable, in
whole or in part, by the Employee other than by will or by the laws of descent
and distribution, and during the lifetime of the Employee the Option shall be
exercisable only by the Employee or by his/her guardian or legal


                                     -2-



representative. Notwithstanding the foregoing, the Employee may transfer this
Option to (i) a member of his immediate family, (ii) a partnership or limited
liability company of which the only partners or members are members of his
immediate family, or (iii) a trust established solely for the benefit of his
immediate family members. Any transferee of this Option shall hold this
Option subject to all of the terms and conditions applicable to this Option
prior to such transfer

         8. TERMINATION OF EMPLOYMENT. If the Employee's employment with the
Company and all Related Corporations, as defined in the Plan, is terminated for
any reason other than death or disability prior to the Expiration Date of this
Option as set forth in Paragraph 3, this Option shall vest and become
exercisable in the following manner:

              (i)  TERMINATION FOR CAUSE OR VOLUNTARY TERMINATION WITHOUT
GOOD REASON. If the Employee is terminated for "Cause", as defined in
Section 4.3 of the Employment Agreement, or if the Employee voluntarily
leaves his employment with the Company (other than for "Good Reason", as
defined in Section 4.4 of the Employment Agreement, or "Disability", as
defined in Section 4.2 of the Employment Agreement) prior to December
31, 2005, then the portion of this Option that is vested on the date of
termination shall be exercisable until the Expiration Date and the
non-vested portion of this Option shall terminate on the date of termination.

              (ii) TERMINATION WITHOUT CAUSE OR BY EMPLOYEE FOR GOOD REASON.
If Employee is terminated without "Cause" or terminates employment for
"Good Reason", then this Option shall become immediately vested and
exercisable and shall remain exercisable in full until the Expiration Date.

              (iii)  TERMINATION AFTER DECEMBER 31, 2005. If the Employee's
employment terminates for any reason following December 31, 2005 (including
if the Employment Agreement is not renewed following December 31, 2005), then
this Option shall remain exercisable in full until the Expiration Date.

         9. DISABILITY. If the Employee is terminated for Disability during his
employment and prior to the Expiration Date of this Option as set forth in
Paragraph 3, the vested portion of this Option shall be exercisable until the
later of (i) one year from the date of termination or (ii) December 31, 2005,
but in no event beyond the Expiration Date, and the non-vested portion of this
Option shall terminate on the date of termination.

         10. DEATH. If the Employee dies during his employment and prior to the
Expiration Date, or if the Employee dies during any period following termination
of employment but while this Option is still exercisable, then the vested
portion of this Option shall be exercisable by the Employee's estate, personal
representative or beneficiary who acquired the right to exercise this Option by
bequest or inheritance or by reason of the Employee's death at any time prior to
the later of (i) December 31, 2005 or (ii) one (1) year after the Employee's
death, but in no event beyond the Expiration Date, and the non-vested portion of
this Option shall terminate on the date of Employee's death.

         11. WITHHOLDING OF TAXES. The obligation of the Company to deliver
shares of Common Stock upon the exercise of the Option shall be subject to
applicable federal, state and local tax withholding requirements. If the
exercise of any Option is subject to the withholding requirements of applicable
federal, state or local tax laws, the Committee, in its discretion, may permit
the Employee, subject to the provisions of the Plan (as in effect on the date of
this Stock Option Grant and Agreement) and such additional withholding rules
(the "Withholding Rules") as shall be adopted by the Committee, to satisfy the


                                      -3-




withholding tax, in whole or in part, by electing to have the Company withhold
(or by returning to the Company) shares of Common Stock, which shares shall be
valued, for this purpose, at their fair market value on the date of exercise of
the Option (or, if later, the date on which the Employee recognizes ordinary
income with respect to such exercise). An election to use shares of Common Stock
to satisfy tax withholding requirements must be made in compliance with and
subject to the Withholding Rules. The Committee may not withhold shares in
excess of the number necessary to satisfy the minimum tax withholding
requirements.

         12.      ADJUSTMENT OF AND CHANGES IN THE COMMON STOCK.

                  (a) In the event the outstanding shares of the Common Stock
shall be changed into an increased number of shares, through a share dividend or
a split-up of shares, or into a decreased number of shares, through a
combination of shares, then immediately after the record date for such change,
the number of shares of Common Stock then subject to the Option shall be
proportionately increased, in case of such share dividend or split-up of shares,
or proportionately decreased, in case of such combination of shares. In the
event the Company shall issue any of its shares of Common Stock or other
securities or property (other than common stock which is covered by the
preceding sentence), in a reclassification of the Common Stock (including
without limitation any such reclassification in connection with a consolidation
or merger in which the Company is the continuing entity), the Option shall be
adjusted so that the Employee shall be entitled to receive upon exercise of the
Option the same kind and number of shares or other securities or property which
the Employee would have owned or have been entitled to receive after the
happening of any of the events described above, had he owned the shares of the
Common Stock subject to the Option immediately prior to the happening of such
event or any record date with respect thereto, which adjustment shall become
effective immediately after the effective date of such event retroactive to the
record date, if any, for such event.

                  (b) In the event the Company shall distribute to all holders
of the Common Stock evidences of its indebtedness or assets (including leveraged
recapitalizations with special cash distributions), but excluding regular
quarterly cash dividends, then in each case the number of shares of Common Stock
thereafter subject to the Option shall be determined by multiplying the number
of shares theretofore subject to the Option by a fraction, (i) the numerator of
which shall be the then current market price per share of Common Stock (as
determined in paragraph (c) below) on the record date for such distribution, and
(ii) the denominator of which shall be the then current market price per share
of the Common Stock less the then fair value (as mutually determined in good
faith by the Board of Directors of the Company (the "Board") and the Employee)
of the portion of the assets or evidences of indebtedness so distributed
applicable to a share of Common Stock. Such adjustment shall be made whenever
any such distribution is made, and shall become effective on the date of
distribution retroactive to the record date for the determination of
shareholders entitled to receive such distribution.

                  (c) For the purpose of any computation under paragraph (b) of
this Section 12, the current market price per share of the Common Stock at any
date shall be deemed to be the average of the daily Stock Prices for 15
consecutive Trading Days commencing 20 Trading Days before the date of such
computation. "Stock Price" for each Trading Day shall be the "Fair Market Value"
of the Common Stock (as defined in the Plan, as in effect on the date of this
Stock Option Grant and Agreement) for such Trading Day. "Trading Day" shall be
each Monday, Tuesday, Wednesday, Thursday and Friday, other than any day on
which the Common Stock is not traded on the exchange or in the market which is
the principal United States market for the Common Stock.

                  (d) Notwithstanding anything in this Agreement to the
contrary, in the event of a spin-off by the Company to its shareholders, the
adjustment of the Option shall be determined in an appropriate


                                      -4-



and equitable manner, and it is the intention of the parties hereto that, to
the extent practicable, such adjustment shall include an option grant to
acquire an equity interest in the spun-off entity.

                  (e) Whenever the number of shares of Common Stock subject to
the Option is adjusted as herein provided, the purchase price per share of
Common Stock issuable thereunder shall be adjusted by multiplying such purchase
price immediately prior to such adjustment by a fraction, the numerator of which
shall be the number of shares of Common Stock subject to the Option immediately
prior to such adjustment, and the denominator of which shall be the number of
shares of Common Stock subject to the Option immediately thereafter.

                  (f) For the purpose of this Section 12, the term "Common
Stock" shall mean (i) the class of Company securities designated as the Common
Stock at the date of this Stock Option and Grant Agreement, or (ii) any other
class of equity interest resulting from successive changes or reclassifications
of such shares consisting solely of changes in par value, or from par value to
no par value, or from no par value to par value. In the event that at any time,
as a result of an adjustment made pursuant to the second sentence of Section
12(a) above, the Employee shall become entitled to, upon exercise of the Option,
any shares other than the Common Stock, thereafter the number of such other
shares issuable on exercise of the Option and the exercise price per share of
Common Stock issuable thereunder shall be subject to adjustment from time to
time in a manner and on the terms as nearly equivalent as practicable to the
provisions with respect to the shares contained in this Section 12 and the
provisions of this Stock Option and Grant Agreement with respect to the shares
of Common Stock issuable on exercise of the Option shall apply on like terms to
any such other shares.

                  (g) In case of any consolidation of the Company or merger of
the Company with another corporation as a result of which Common Stock is
converted or modified or in case of any sale or conveyance to another
corporation of the property, assets and business of the Company as an entirety
or substantially as an entirety, the Company shall modify the Option so as to
provide the Employee with an option for the kind and amount of shares and other
securities and property that he would have owned or have been entitled to
receive immediately after the happening of such consolidation, merger, sale or
conveyance had the Option, immediately prior to such action, actually been
exercised for shares and, if applicable, other securities of the Company subject
to the Option. The provisions of this Section 12(g) shall similarly apply to
successive consolidations, mergers, sales or conveyances.

                  (h) Notwithstanding anything to the contrary contained herein,
the provisions of this Section 12 shall not apply to, and no adjustment is
required to be made in respect of, any of the following: (i) the issuance of
shares of Common Stock upon the exercise of any other rights, options or
warrants that entitle the holder to subscribe for or purchase such shares (it
being understood that the sole adjustment pursuant to this Section 12 in respect
of the issuance of shares of Common Stock upon exercise of rights, options or
warrants shall be made at the time of the issuance by the Company of such
rights, options or warrants, or a change in the terms thereof); (ii) the
issuance of shares of Common Stock to the Company's employees, directors or

length transaction (including, without limitation, any acquisition, financing,
private placement, or, except as provided in Section 12(g), merger or
combination or consolidation), directly or indirectly, to any party.

                  (i) In the event the parties hereto cannot agree upon an
appropriate and equitable


                                      -5-



adjustment to the Option, the services of an independent investment banker
mutually acceptable to Employee and the Company shall (at the sole expense of
the Company) be retained to determine an appropriate and equitable
adjustment, and such determination shall be binding upon the parties.

                  (j) For purposes of this Stock Grant and Option Agreement,

reasonably incurred by Employee in connection with such contest or dispute to
the extent set forth in Section 8.1 of the Employment Agreement. The application
of this Section 13 (and Section 8.1 of the Employment Agreement) shall survive
the termination of the Employment Agreement. Such reimbursement shall be made as
soon as practicable following the resolution of such contest or dispute (whether
or not appealed) to the extent the Company receives reasonable written evidence
of such fees and expenses. Notwithstanding any determination or interpretation
by the Committee, any dispute or controversy arising under or in connection with
this Agreement, shall be settled exclusively by arbitration in Wilmington,
Delaware in accordance with the Commercial Arbitration Rules of the American
Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction.

         14. CONSTRUCTION. Except as would be in conflict with any specific
provision herein, this Stock Option Grant and Agreement is made under and
subject to the provisions of the Plan as in effect on the Grant Date and, except
as would conflict with the provisions of this Stock Option Grant and Agreement,
all of the provisions of the Plan as in effect on the Grant Date are hereby

the Company, and such waiver is set forth in writing and signed by the party to

at the same time, any prior time or any subsequent time.

                    INTEGRA LIFESCIENCES HOLDINGS CORPORATION


                        STOCK OPTION GRANT AND AGREEMENT
                                   PURSUANT TO
                           2000 EQUITY INCENTIVE PLAN


         STOCK OPTION GRANT AND AGREEMENT made as of the 22nd day of December,
2000 (the "Grant Date"), between INTEGRA LIFESCIENCES HOLDINGS CORPORATION, a
Delaware corporation (the "Company"), and STUART M. ESSIG, an employee of the
Company (the "Employee").

         WHEREAS, the Company desires to afford the Employee an opportunity to
purchase shares of common stock of the Company ("Common Stock"), par value $.01
per share, as hereinafter provided, under the Integra LifeSciences Holdings
Corporation 2000 Equity Incentive Plan (the "Plan"), a copy of which is
attached.

         NOW THEREFORE, in consideration of the mutual covenants hereinafter set
forth and for other good and valuable consideration the legal sufficiency of
which is hereby acknowledged, the parties hereto, intending to be legally bound
hereby, agree as follows:

         1. GRANT OF OPTION. Pursuant to the Amended and Restated Employment
Agreement by and between the Employee and the Company dated as of December 22,
2000 (the "Employment Agreement"), the Company hereby grants to the Employee a
non-qualified stock option (the "Option") to purchase all or any part of an
aggregate of 250,000 shares of Common Stock.

         2. PURCHASE PRICE. The purchase price per share of the shares of Common
Stock covered by the Option shall be $11.00. It is the determination of the
Company's Stock Option Committee (the "Committee") that on the Grant Date the
purchase price per share was not less than the greater of one hundred percent
(100%) of the fair market value of the Common Stock, or the par value thereof.

         3. TERM. Unless earlier terminated pursuant to any provision of this
Stock Option Grant and Agreement or the Employment Agreement, this Option shall
expire on December 21, 2010 (the "Expiration Date"), which date is not more than
ten (10) years from the Grant Date. Notwithstanding anything herein to the
contrary, this Option shall not be exercisable after the Expiration Date.


         4. EXERCISE OF OPTION. The Committee, using its authority and
discretion under Sections 3(b) and 7.1 of the Plan to set the terms of Options
granted under the Plan, has determined that this Option, subject to law and
regulation, shall vest and become exercisable in such installments and on such
dates, as follows:

                  This Option shall vest and become exercisable with respect to
                  62,500 shares on the second anniversary of the date hereof.
                  Thereafter, this Option shall vest and become exercisable with
                  respect to 1/36th of the remaining shares on the first
                  business day of each following month. Except as provided in
                  Section 8(i) hereof, this Option shall vest and become
                  exercisable in its entirety, and shall remain exercisable
                  until the Expiration Date, (i) upon

                                      -1-



                  the occurrence of a "Change in Control" (as defined in the
                  Employment Agreement), or (ii) upon the receipt of a BONA
                  FIDE two-tier tender offer with respect to the outstanding
                  shares of Common Stock.

                  The portion of the Option that becomes exercisable in
accordance with the foregoing shall remain exercisable, subject to the
provisions contained in this Stock Option Grant and Agreement, until the
expiration of the term of this Option as set forth in Paragraph 3 or until other
termination of the Option as set forth in this Stock Option Grant and Agreement.

         5. METHOD OF EXERCISING OPTION. Subject to the terms and conditions of
this Stock Option Grant and Agreement, the Option may be exercised in whole or
in part by written notice to the Company, at its principal office, which is
located at 311C Enterprise Drive, Plainsboro, New Jersey 08536. Such notice
shall state the election to exercise the Option, and the number of shares with
respect to which it is being exercised, shall be signed by the person or persons
so exercising the Option; shall, unless the Company otherwise notifies the
Employee, be accompanied by the investment certificate referred to in Section 6;
and shall be accompanied by payment of the full Option price of such shares.

                  The Option price shall be paid to the Company in: (i) cash;
(ii) cash equivalent; (iii) Common Stock of the Company, in accordance with
Section 7.1(f)(ii) of the Plan (as in effect on the date of this Stock Option
Grant and Agreement); (iv) any combination of (i)-(iii); or (v) by delivering a
properly executed notice of exercise of the Option in accordance with Section
7.1(f)(iv) of the Plan (as in effect on the date of this Stock Option Grant and
Agreement).

                  Upon receipt of such notice and payment, the Company, as
promptly as practicable, shall deliver or cause to be delivered a certificate or
certificates representing the shares with respect to which the Option is so
exercised. Such certificate(s) shall be registered in the name of the person or
persons so exercising the Option (or, if the Option is exercised by the Employee
and if the Employee so requests in the notice exercising the Option, shall be
registered in the name of the Employee and the Employee's spouse, jointly, with
right of survivorship) and shall be delivered as provided above to or upon the
written order of the person or persons exercising the Option. In the event the
Option is exercised by any person or persons after the legal disability or death
of the Employee, such notice shall be accompanied by appropriate proof of the
right of such person or persons to exercise the Option. All shares that are
purchased upon the exercise of the Option as provided herein shall be fully paid
and not assessable by the Company.

         6. SHARES TO BE PURCHASED FOR INVESTMENT. Unless the Company has
theretofore notified the Employee that a registration statement covering the
shares to be acquired upon the exercise of the Option has become effective under
the Securities Act of 1933 and the Company has not thereafter notified the
Employee that such registration statement is no longer effective, it shall be a
condition to any exercise of this Option that the shares acquired upon such
exercise be acquired for investment and not with a view to distribution, and the
person effecting such exercise shall submit to the Company a certificate of such
investment intent, together with such other evidence supporting the same as the
Company may request. Notwithstanding the foregoing, upon the written request of
Employee, the Company shall provide the Employee with a shelf registration
pursuant to a registration statement subject to the terms set forth in EXHIBIT B
to the Employment Agreement. The Company shall be entitled to delay the
transferability of the shares issued upon any such exercise to the extent
necessary to avoid a risk of violation of the Securities Act of 1933 (or of any
rules or regulations promulgated thereunder) or of any state laws or
regulations. Such restrictions may, at the option of the Company, be noted or
set forth in full on the share certificates. If any law or regulation requires
the Company to take any additional action regarding the Common Stock before the
Company issues certificates for the Common Stock subject to this Option or
before such Common Stock may be transferred by the Employee, the Company shall
use its commercially reasonable best efforts to


                                     -2-



resolve such problem.

         7. TRANSFERABILITY. This Option is not assignable or transferable, in
whole or in part, by the Employee other than by will or by the laws of descent
and distribution, and during the lifetime of the Employee the Option shall be
exercisable only by the Employee or by his/her guardian or legal representative.

         8. TERMINATION OF EMPLOYMENT. If the Employee's employment with the
Company and all Related Corporations, as defined in the Plan, is terminated for
any reason other than death or disability prior to the Expiration Date of this
Option as set forth in Paragraph 3, this Option shall vest and become
exercisable in the following manner:

                  (i) TERMINATION FOR CAUSE OR VOLUNTARY TERMINATION WITHOUT
GOOD REASON. If the Employee is terminated for "Cause", as defined in Section
4.3 of the Employment Agreement, or if the Employee voluntarily leaves his
employment with the Company (other than for "Good Reason", as defined in Section
4.4 of the Employment Agreement, or "Disability", as defined in Section 4.2 of
the Employment Agreement) prior to December 31, 2005, then the portion of this
Option that is vested on the date of termination shall be exercisable until the
Expiration Date and the non-vested portion of this Option shall terminate on the
date of termination.

                  (ii) TERMINATION WITHOUT CAUSE OR BY EMPLOYEE FOR GOOD REASON.
If Employee is terminated without "Cause" or terminates employment for "Good
Reason", then this Option shall become immediately vested and exercisable and
shall remain exercisable in full until the Expiration Date.

                  (iii) TERMINATION AFTER DECEMBER 31, 2005. If the Employee's
employment terminates for any reason following December 31, 2005 (including if
the Employment Agreement is not renewed following December 31, 2005), then this
Option shall remain exercisable in full until the Expiration Date.

         9. DISABILITY. If the Employee is terminated for Disability during his
employment and prior to the Expiration Date of this Option as set forth in
Section 3, the vested portion of this Option shall be exercisable until the
later of (i) one year from the date of termination or (ii) December 31, 2005,
but in no event beyond the Expiration Date, and the non-vested portion of this
Option shall terminate on the date of termination.

         10. DEATH. If the Employee dies during his employment and prior to the
Expiration Date, or if the Employee dies during any period following termination
of employment but while this Option is still exercisable, then the vested
portion of this Option shall be exercisable by the Employee's estate, personal
representative or beneficiary who acquired the right to exercise this Option by
bequest or inheritance or by reason of the Employee's death at any time prior to
the later of (i) December 31, 2005 or (ii) one (1) year after the Employee's
death, but in no event beyond the Expiration Date, and the non-vested portion of
this Option shall terminate on the date of Employee's death.

         11. WITHHOLDING OF TAXES. The obligation of the Company to deliver
shares of Common Stock upon the exercise of the Option shall be subject to
applicable federal, state and local tax withholding requirements. If the
exercise of any Option is subject to the withholding requirements of applicable
federal, state or local tax laws, the Committee, in its discretion, may permit
the Employee, subject to the provisions of the Plan (as in effect on the date of
this Stock Option Grant and Agreement) and such additional withholding rules
(the "Withholding Rules") as shall be adopted by the Committee, to satisfy the


                                     -3-




withholding tax, in whole or in part, by electing to have the Company withhold
(or by returning to the Company) shares of Common Stock, which shares shall be
valued, for this purpose, at their fair market value on the date of exercise of
the Option (or, if later, the date on which the Employee recognizes ordinary
income with respect to such exercise). An election to use shares of Common Stock
to satisfy tax withholding requirements must be made in compliance with and
subject to the Withholding Rules. The Committee may not withhold shares in
excess of the number necessary to satisfy the minimum tax withholding
requirements.

         12.      ADJUSTMENT OF AND CHANGES IN THE COMMON STOCK.

                  (a) In the event the outstanding shares of the Common Stock
shall be changed into an increased number of shares, through a share dividend or
a split-up of shares, or into a decreased number of shares, through a
combination of shares, then immediately after the record date for such change,
the number of shares of Common Stock then subject to the Option shall be
proportionately increased, in case of such share dividend or split-up of shares,
or proportionately decreased, in case of such combination of shares. In the
event the Company shall issue any of its shares of Common Stock or other
securities or property (other than common stock which is covered by the
preceding sentence), in a reclassification of the Common Stock (including
without limitation any such reclassification in connection with a consolidation
or merger in which the Company is the continuing entity), the Option shall be
adjusted so that the Employee shall be entitled to receive upon exercise of the
Option the same kind and number of shares or other securities or property which
the Employee would have owned or have been entitled to receive after the
happening of any of the events described above, had he owned the shares of the
Common Stock subject to the Option immediately prior to the happening of such
event or any record date with respect thereto, which adjustment shall become
effective immediately after the effective date of such event retroactive to the
record date, if any, for such event.

                  (b) In the event the Company shall distribute to all holders
of the Common Stock evidences of its indebtedness or assets (including leveraged
recapitalizations with special cash distributions), but excluding regular
quarterly cash dividends, then in each case the number of shares of Common Stock
thereafter subject to the Option shall be determined by multiplying the number
of shares theretofore subject to the Option by a fraction, (i) the numerator of
which shall be the then current market price per share of Common Stock (as
determined in paragraph (c) below) on the record date for such distribution, and
(ii) the denominator of which shall be the then current market price per share
of the Common Stock less the then fair value (as mutually determined in good
faith by the Board of Directors of the Company (the "Board") and the Employee)
of the portion of the assets or evidences of indebtedness so distributed
applicable to a share of Common Stock. Such adjustment shall be made whenever
any such distribution is made, and shall become effective on the date of
distribution retroactive to the record date for the determination of
shareholders entitled to receive such distribution.

                  (c) For the purpose of any computation under paragraph (b) of
this Section 12, the current market price per share of the Common Stock at any
date shall be deemed to be the average of the daily Stock Prices for 15
consecutive Trading Days commencing 20 Trading Days before the date of such
computation. "Stock Price" for each Trading Day shall be the "Fair Market Value"
of the Common Stock (as defined in the Plan, as in effect on the date of this
Stock Option Grant and Agreement) for such Trading Day. "Trading Day" shall be
each Monday, Tuesday, Wednesday, Thursday and Friday, other than any day on
which the Common Stock is not traded on the exchange or in the market which is
the principal United States market for the Common Stock.

                  (d) Notwithstanding anything in this Agreement to the
contrary, in the event of a spin-off by the Company to its shareholders, the
adjustment of the Option shall be determined in an appropriate


                                      -4-



and equitable manner, and it is the intention of the parties hereto that, to
the extent practicable, such adjustment shall include an option grant to
acquire an equity interest in the spun-off entity.

                  (e) Whenever the number of shares of Common Stock subject to
the Option is adjusted as herein provided, the purchase price per share of
Common Stock issuable thereunder shall be adjusted by multiplying such purchase
price immediately prior to such adjustment by a fraction, the numerator of which
shall be the number of shares of Common Stock subject to the Option immediately
prior to such adjustment, and the denominator of which shall be the number of
shares of Common Stock subject to the Option immediately thereafter.

                  (f) For the purpose of this Section 12, the term "Common
Stock" shall mean (i) the class of Company securities designated as the Common
Stock at the date of this Stock Option and Grant Agreement, or (ii) any other
class of equity interest resulting from successive changes or reclassifications
of such shares consisting solely of changes in par value, or from par value to
no par value, or from no par value to par value. In the event that at any time,
as a result of an adjustment made pursuant to the second sentence of Section
12(a) above, the Employee shall become entitled to, upon exercise of the Option,
any shares other than the Common Stock, thereafter the number of such other
shares issuable on exercise of the Option and the exercise price per share of
Common Stock issuable thereunder shall be subject to adjustment from time to
time in a manner and on the terms as nearly equivalent as practicable to the
provisions with respect to the shares contained in this Section 12 and the
provisions of this Stock Option and Grant Agreement with respect to the shares
of Common Stock issuable on exercise of the Option shall apply on like terms to
any such other shares.

                  (g) In case of any consolidation of the Company or merger of
the Company with another corporation as a result of which Common Stock is
converted or modified or in case of any sale or conveyance to another
corporation of the property, assets and business of the Company as an entirety
or substantially as an entirety, the Company shall modify the Option so as to
provide the Employee with an option for the kind and amount of shares and other
securities and property that he would have owned or have been entitled to
receive immediately after the happening of such consolidation, merger, sale or
conveyance had the Option, immediately prior to such action, actually been
exercised for shares and, if applicable, other securities of the Company subject
to the Option. The provisions of this Section 12(g) shall similarly apply to
successive consolidations, mergers, sales or conveyances.

                  (h) Notwithstanding anything to the contrary contained herein,
the provisions of this Section 12 shall not apply to, and no adjustment is
required to be made in respect of, any of the following: (i) the issuance of
shares of Common Stock upon the exercise of any other rights, options or
warrants that entitle the holder to subscribe for or purchase such shares (it
being understood that the sole adjustment pursuant to this Section 12 in respect
of the issuance of shares of Common Stock upon exercise of rights, options or
warrants shall be made at the time of the issuance by the Company of such
rights, options or warrants, or a change in the terms thereof); (ii) the
issuance of shares of Common Stock to the Company's employees, directors or
consultants pursuant to bona fide benefit plans or employment or consulting
arrangements adopted by the Company's Board of Directors; (iii) the issuance of
shares of Common Stock in a bona fide public offering; (iv) the issuance of
shares of Common Stock pursuant to any dividend reinvestment or similar plan
adopted by the Company's Board of Directors to the extent that the applicable
discount from the current market price for shares issued under such plan does
not exceed 5%; and (v) the issuance of shares of Common Stock in any arm's
length transaction (including, without limitation, any acquisition, financing,
private placement, or, except as provided in Section 12(g), merger or
combination or consolidation), directly or indirectly, to any party.

                  (i) In the event the parties hereto cannot agree upon an
appropriate and equitable


                                      -5-



adjustment to the Option, the services of an independent investment banker
mutually acceptable to Employee and the Company shall (at the sole expense of
the Company) be retained to determine an appropriate and equitable
adjustment, and such determination shall be binding upon the parties.

                  (j) For purposes of this Stock Grant and Option Agreement,
"Affiliate" of an entity or individual means any entity or individual, directly
or indirectly, controlling, controlled by or under common control with such
entity or individual.

         13. LEGAL FEES. If any contest or dispute shall arise between the
Company and the Employee regarding any provisions of this Stock Grant and Option
Agreement, the Company shall reimburse the Employee for legal fees and expenses
reasonably incurred by Employee in connection with such contest or dispute to
the extent set forth in Section 8.1 of the Employment Agreement. The application
of this Section 13 (and Section 8.1 of the Employment Agreement) shall survive
the termination of the Employment Agreement. Such reimbursement shall be made as
soon as practicable following the resolution of such contest or dispute (whether
or not appealed) to the extent the Company receives reasonable written evidence
of such fees and expenses. Notwithstanding any determination or interpretation
by the Committee, any dispute or controversy arising under or in connection with
this Agreement, shall be settled exclusively by arbitration in Wilmington,
Delaware in accordance with the Commercial Arbitration Rules of the American
Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction.

         14. CONSTRUCTION. Except as would be in conflict with any specific
provision herein, this Stock Option Grant and Agreement is made under and
subject to the provisions of the Plan as in effect on the Grant Date and, except
as would conflict with the provisions of this Stock Option Grant and Agreement,
all of the provisions of the Plan as in effect on the Grant Date are hereby
incorporated herein as provisions of this Stock Option Grant and Agreement. In
the event of any such conflict, the terms of this Stock Option Grant and
Agreement shall govern.

         15. GOVERNING LAW. This Stock Option Grant and Agreement shall be
governed by applicable federal law and otherwise by the laws of the State of
Delaware.

         16. AMENDMENT OR MODIFICATION: WAIVER. No provision of this Agreement
may be amended, modified or waived unless such amendment or modification is
agreed to in writing, signed by the Employee and by a duly authorized officer of
the Company, and such waiver is set forth in writing and signed by the party to
be charged. No waiver by any party hereto of any breach by another party hereto
of any condition or provision of this Agreement to be performed by such other
party shall be deemed a waiver of a similar or dissimilar condition or provision
at the same time, any prior time or any subsequent time.

         IN WITNESS WHEREOF, the undersigned have executed this Stock Option
Grant and Agreement as of the date first written above.

                                      -6-





                                                                    EXHIBIT 4.3
                           RESTRICTED UNITS AGREEMENT

                  AGREEMENT, dated as of December 22, 2000, by and between
Integra LifeSciences Holdings Corporation, a Delaware corporation (the
"Company"), and Stuart M. Essig ("Executive").

                  WHEREAS, the Company and Executive have entered into an
Amended and Restated Employment Agreement (the "Employment Agreement"), dated as
of December 22, 2000, pursuant to which Executive will continue to serve as
President and Chief Executive Officer of the Company, on the terms and
conditions set forth and described therein; and

                  WHEREAS, pursuant to the Employment Agreement, the Company has
agreed to grant to Executive an aggregate of 1,250,000 restricted units (the
"Units") representing an equal number of shares of restricted common stock of
the Company, par value $.01 per share ("Common Stock"), on the terms set forth
herein; and

                  WHEREAS, the grant of Units and restricted Common Stock
hereunder is being made under the Integra LifeSciences Holdings Corporation 2000
Equity Incentive Plan (the "Plan"), a copy of which is attached.

                  NOW, THEREFORE, the parties agree as follows:

         1. DEFINITIONS. Capitalized terms not otherwise defined herein shall
have the meaning set forth in the Employment Agreement, unless otherwise
indicated.

         2. GRANT OF UNITS. Pursuant to the Employment Agreement, Executive is
hereby granted, as of December 22, 2000, deferred compensation in the form of
1,250,000 (one million two hundred fifty thousand) Units pursuant to the terms
of this Agreement.

         3. DIVIDEND EQUIVALENTS. Executive shall be paid, on a quarterly basis
with respect to all outstanding Units (as such Units may be adjusted under
Section 6), dividend equivalent amounts equal to the regular quarterly cash
dividend payable to holders of Common Stock (to the extent regular quarterly
cash dividends are paid) as if Executive were an actual shareholder with respect
to the number of shares of Common Stock equal to his outstanding Units. Such
dividend equivalents shall be paid on the same date as the regular quarterly
cash dividend is paid by the Company in respect of the Common Stock.

         4. PAYMENTS OF UNITS.

                  (a) The shares of Common Stock underlying the Units (the "Unit
Shares") shall be paid out to Executive on January 1, 2006, if Executive is
still employed by the Company on December 31, 2005; provided, however, that
during the 20-year period ending June 30, 2025, Executive shall have the right
to defer the delivery of the Unit Shares on as many occasions as Executive
determines from time to time by giving written notice to the Company no less
than six months prior to the next scheduled delivery date for the Unit Shares
(but in no event shall Executive defer delivery of the Unit Shares beyond June
30, 2025). In the event Executive's employment with the Company terminates prior
to December 31, 2005 or a Change in Control occurs, the timing of the payment of
the Unit Shares shall be governed by the terms of the Employment Agreement.

                  (b) Any Unit Shares delivered shall be deposited in an account
designated by Executive and maintained at a brokerage house selected by
Executive. Any such Unit Shares shall be





duly authorized, fully paid and non-assessable shares, listed with NASDAQ or
the principal United States securities exchange on which the Common Stock is
admitted to trading and registered on the Company Registration Statement, if
registration is requested by Executive.

                  (c) Except as otherwise provided in this Agreement, Executive
shall not be deemed to be a holder of any Common Stock pursuant to a Unit until
the date of the issuance of a certificate to him for such shares and, except as
otherwise provided in this Agreement, Executive shall not have any rights to
dividends or any other rights of a shareholder with respect to the shares of
Common Stock covered by a Unit until such shares of Common Stock have been
issued to him, which issuance shall not be unreasonably delayed.

                  (d) The Company may require that Executive pay to the Company,
or the Company may otherwise withhold, at the time of payment of the value of a
Unit, any such amount as is required by law or regulation to be withheld for
Federal, state or local income tax or any other taxes incurred by reason of the
payment.

                  (e) Executive's right to receive payment of any amounts under
this Agreement shall be an unfunded entitlement and shall be an unsecured claim
against the general assets of the Company.

                  (f) After payment in accordance with this Section 4, the Unit
Shares may not be sold, transferred or otherwise disposed of by Executive for a
period of five days after receipt of such shares by Executive, except that no
such restrictions shall apply in the case of a Change in Control or if Executive
determines to sell (or instruct the Company to withhold) any Unit Shares in
order to satisfy any obligations Executive may have with respect to any
applicable tax withholding requirements on receipt of Unit Shares.

         5. REPRESENTATIONS. The Company represents and warrants that this
Agreement has been authorized by all necessary action of the Company, has been
approved by the Board and is a valid and binding agreement of the Company
enforceable against it in accordance with its terms and that the Unit Shares
will be issued pursuant to and in accordance with the 2000 Plan, will be listed
with NASDAQ or the principal United States securities exchange on which the
Common Stock is admitted to trading, and will be validly issued, fully paid and
non-assessable shares. The Company further represents and warrants that the
grant of Units under this Agreement has been approved by the Company's Stock
Option Committee, that the 2000 Plan has and will have sufficient shares
available to effect the distribution of the Unit Shares, and that the Company
will file a Hart Scott Rodino application with respect to Executive on a timely
basis, if necessary, in connection with the acquisition of Unit Shares by
Executive under this Agreement.

         6. CHANGES IN THE COMMON STOCK AND ADJUSTMENT OF UNITS.

                  (a) In the event the outstanding shares of the Common Stock
shall be changed into an increased number of shares, through a share dividend or
a split-up of shares, or into a decreased number of shares, through a
combination of shares, then immediately after the record date for such change,
the number of Units then subject to this Agreement shall be proportionately
increased, in case of such share dividend or split-up of shares, or
proportionately decreased, in case of such combination of shares. In the event
the Company shall issue any of its shares of stock or other securities or
property (other than Common Stock which is covered by the preceding sentence),
in a reclassification of the Common Stock (including without limitation any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing entity), the kind and number of Units subject to this
Agreement immediately prior thereto shall be adjusted so that the Executive
shall be entitled to receive


                                     -2-



the same kind and number of shares or other securities or property which the
Executive would have owned or have been entitled to receive after the
happening of any of the events described above, had he owned the shares of
the Common Stock represented by the Units under this Agreement immediately
prior to the happening of such event or any record date with respect thereto,
which adjustment shall become effective immediately after the effective date
of such event retroactive to the record date, if any, for such event.

                  (b) In the event the Company shall distribute to all holders
of the Common Stock evidences of its indebtedness or assets (including leveraged
recapitalizations with special cash distributions, but excluding regular
quarterly cash dividends), then in each case the number of Units thereafter
subject to this Agreement shall be determined by multiplying the number of Units
theretofore subject to this Agreement by a fraction, (i) the numerator of which
shall be the then current market price per share of Common Stock (as determined
in paragraph (c) below) on the record date for such distribution, and (ii) the
denominator of which shall be the then current market price per share of the
Common Stock less the then fair value (as mutually determined in good faith by
the Board and the Executive) of the portion of the assets or evidences of
indebtedness so distributed applicable to a share of Common Stock. Such
adjustment shall be made whenever any such distribution is made, and shall
become effective on the date of distribution retroactive to the record date for
the determination of shareholders entitled to receive such distribution.

                  (c) For the purpose of any computation under paragraph (b) of
this Section 6, the current market price per share of the Common Stock at any
date shall be deemed to be the average of the daily Stock Prices for 15
consecutive Trading Days commencing 20 Trading Days before the date of such
computation. "Stock Price" for each Trading Day shall be the "Fair Market Value"
of the Common Stock (as defined in the Company Stock Option Plan, as in effect
on the date of this Agreement) for such Trading Day. "Trading Day" shall be each
Monday, Tuesday, Wednesday, Thursday and Friday, other than any day on which the
Common Stock is not traded on the exchange or in the market which is the
principal United States market for the Common Stock.

                  (d) For the purpose of this Section 6, the term "Common Stock"
shall mean (i) the class of Company securities designated as the Common Stock at
the date of this Agreement, or (ii) any other class of equity interest resulting
from successive changes or reclassifications of such shares consisting solely of
changes in par value, or from par value to no par value, or from no par value to
par value. In the event that at any time, as a result of an adjustment made
pursuant to the second sentence of Section 6(a) above, the Executive shall
become entitled to Units representing any shares other than the Common Stock,
thereafter the number of such other shares represented by a Unit shall be
subject to adjustment from time to time in a manner and on the terms as nearly
equivalent as practicable to the provisions with respect to the shares contained
in this Section 6, and the provisions of this Agreement with respect to the
shares of Common Stock represented by the Units shall apply on like terms to any
such other shares.

                  (e) In case of any consolidation of the Company or merger of
the Company with another corporation as a result of which Common Stock is
converted or modified, or in case of any sale or conveyance to another
corporation of the property, assets and business of the Company as an entirety
or substantially as an entirety, the Company shall modify the Units so as to
provide the Executive with Units reflecting the kind and amount of shares and
other securities and property that he would have owned or have been entitled to
receive immediately after the happening of such consolidation, merger, sale or
conveyance had his Units immediately prior to such action actually been shares
and, if applicable, other securities of the Company represented by those Units.
The provisions of this Section 6(e) shall similarly apply to successive
consolidations, mergers, sales or conveyances.


                                     -3-




                  (f) If the Company distributes rights or warrants to all
holders of its Common Stock entitling them to purchase shares of Common Stock at
a price per share less than the current market price per share on the record
date for the distribution, the Company shall distribute to Executive equivalent
amounts of such rights or warrants as if Executive were an actual shareholder
with respect to the number of shares of Common Stock equal to his outstanding
Units. Such rights or warrants shall be exercisable at the same time, on the
same terms, and for the same price as the rights or warrants distributed to
holders of the Common Stock.

                  (g) In case any event shall occur as to which the provisions
of this Section 6 are not applicable but the failure to make any adjustment
would not fairly protect the rights represented by the Units in accordance with
the essential intent and principles of this Section 6 then, in each such case,
the Company shall make an adjustment, if any, on a basis consistent with the
essential intent and principles established in this Section 6, necessary to
preserve, without dilution, the rights represented by the Units. The Company
will promptly notify the Executive of any such proposed adjustment.

                  (h) Notwithstanding anything to the contrary contained herein,
the provisions of Section 6 shall not apply to, and no adjustment is required to
be made in respect of, any of the following: (i) the issuance of shares of
Common Stock upon the exercise of any other rights, options or warrants that
entitle the holder to subscribe for or purchase such shares (it being understood
that the sole adjustment pursuant to this Section 6 in respect of the issuance
of shares of Common Stock upon exercise of rights, options or warrants shall be
made at the time of the issuance by the Company of such rights, options or
warrants, or a change in the terms thereof); (ii) the issuance of shares of
Common Stock to the Company's employees, directors or consultants pursuant to
bona fide benefit plans adopted by the Company's Board; (iii) the issuance of
shares of Common Stock in a bona fide public offering pursuant to a firm
commitment offering; (iv) the issuance of shares of Common Stock pursuant to any
dividend reinvestment or similar plan adopted by the Company's Board to the
extent that the applicable discount from the current market price for shares
issued under such plan does not exceed 5%; and (v) the issuance of shares of
Common Stock in any arm's length transaction, directly or indirectly, to any
party.

                  (i) Notwithstanding anything in this Agreement to the
contrary, in the event of a spin-off by the Company to its shareholders,
Executive's participation in such spin-off with respect to the Units and the
adjustment of the Units shall be determined in an appropriate and equitable
manner, and it is the intention of the parties hereto that, to the extent
practicable, such adjustment shall include an equity interest in the spin-off
entity.

                  (j) In the event the parties hereto cannot agree upon an
appropriate and equitable adjustment to the Units, the services of an
independent investment banker mutually acceptable to Executive and the Company
shall (at the sole expense of the Company) be retained to determine an
appropriate and equitable adjustment, and such determination shall be binding
upon the parties.

         7. NO RIGHT TO EMPLOYMENT. Nothing in this Agreement shall confer upon
Executive the right to remain in employ of the Company or any subsidiary of the
Company.

         8. NONTRANSFERABILITY. This Agreement shall not be assignable or
transferable by the Company (other than to successors of the Company) and this
Agreement and the Units shall not be assignable or transferable by the Executive
otherwise than by will or by the laws of descent and distribution, and the Units
may be paid out during the lifetime of the Executive only to him. More
particularly, but without limiting the generality of the foregoing, the Units
may not be assigned, transferred (except as provided in the preceding sentence),
pledged, or hypothecated in any way (whether by operation of law or otherwise),
and shall not be subject to execution, attachment or similar process. Any
attempted assignment, transfer, pledge, hypothecation or other disposition of
the Units contrary to


                                      -4-



the provisions of this Agreement, and any levy of any attachment or similar
process upon the Units, shall be null and void and without effect.

         9. ARBITRATION, LEGAL FEES AND EXPENSES. If any contest or dispute
shall arise between the Company and Executive regarding any provision of this
Agreement, the Company shall reimburse Executive for all legal fees and expenses
reasonably incurred by Executive in connection with such contest or dispute,
pursuant to the provisions of Section 8.1 of the Employment Agreement. The
application of this Section 9 (and Section 8.1 of the Employment Agreement)
shall survive the termination of the Employment Agreement. Such reimbursement
shall be made as soon as practicable following the resolution of such contest or
dispute (whether or not appealed) to the extent the Company receives reasonable
written evidence of such fees and expenses. Any dispute or controversy arising
under or in connection with this Agreement, shall be settled exclusively by
arbitration in Wilmington, Delaware in accordance with the Commercial
Arbitration Rules of the American Arbitration Association then in effect.
Judgment may be entered on the arbitrator's award in any court having
jurisdiction.

         10. ENTIRE AGREEMENT. This Agreement and the Employment Agreement
contain all the understandings between the parties hereto pertaining to the
matters referred to herein, and supersede all undertakings and agreements,
whether oral or in writing, previously entered into by them with respect
thereto. The Executive represents that, in executing this Agreement, he does not
rely and has not relied upon any representation or statement not set forth
herein made by the Company with regard to the subject matter, basis or effect of
this Agreement or otherwise.

         11. AMENDMENT OR MODIFICATION; WAIVER. No provision of this Agreement
may be amended, modified or waived unless such amendment or modification is
agreed to in writing, signed by the Executive and by a duly authorized officer
of the Company, and such waiver is set forth in writing and signed by the party
to be charged. No waiver by any party hereto of any breach by another party
hereto of any condition or provision of this Agreement to be performed by such
other party shall be deemed a waiver of a similar or dissimilar condition or
provision at the same time, any prior time or any subsequent time.

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         AMENDED AND RESTATED EMPLOYMENT AGREEMENT dated as of December 22,
2000 between Integra LifeSciences Holdings Corporation, a Delaware
corporation ("Company"), and Stuart M. Essig ("Executive").

                                   BACKGROUND

         A. Since December 1997, the Executive has served as the Company's
President and Chief Executive Officer pursuant to the terms and conditions of an
Employment Agreement dated as of December 27, 1997 between the Company and the
Executive (the "Prior Employment Agreement"). Pursuant to the Prior Employment
Agreement, among other things, the Executive was issued (a) a non-qualified
stock option to purchase 1,000,000 shares of Common Stock of the Company (which
now represents the option to purchase 500,000 shares after giving effect to the
Company's one-for-two reverse split of its Common Stock on May 18, 1998) (the
"Original Company Stock Option") and (b) a fully-vested equity-based signing
award bonus in the form of 2,000,000 restricted units (which now represents
1,000,000 restricted units after giving effect to the Company's one-for-two
reverse split of its Common Stock on May 18, 1998) (the "Original Restricted
Units") pursuant to a Restricted Units Agreement dated as of December 27, 1997
(the "Original Restricted Units Agreement"). Pursuant to the registration rights
provisions attached as EXHIBIT B to the Prior Employment Agreement (the
"Original Registration Rights Provisions"), Executive is entitled to certain
registration rights with respect to the shares of Common Stock issuable upon
exercise of the Original Company Stock Option and issuable with respect to the
Original Restricted Units Agreement.

         B. Company and Executive now wish to amend the terms and conditions of
the Prior Employment Agreement to provide for the continued employment of
Executive by the Company on the terms and conditions contained in this
Agreement, which shall supercede and replace the Prior Employment Agreement to
the extent provided herein.

         C. Executive will continue to be substantially involved with Company's
operations and management and will continue to learn trade secrets and other
confidential information relating to Company and its customers; accordingly, the
noncompetition agreement and other restrictive covenants contained in Section 7
of this Agreement constitute essential elements hereof.

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements contained herein and intending to be legally bound hereby, the
parties hereto agree as follows:

                                      TERMS

SECTION 1.  CAPACITY AND DUTIES

              1.1 CONTINUATION OF EMPLOYMENT. Company hereby continues to employ
Executive and Executive hereby accepts the continued employment by Company for
the period and upon the terms and conditions hereinafter set forth.


                                     -1-



              1.2 CAPACITY AND DUTIES.

                  (a) Executive shall serve as President and Chief Executive
Officer of Company. Executive shall perform such other duties and shall have
such authority consistent with his position as may from time to time be
specified by the Board of Directors of Company (the "Board"). Executive shall
report directly to the Board and shall perform his duties for Company
principally at Company's office in Plainsboro, New Jersey, except for travel
that may be necessary or appropriate in connection with the performance of
Executive's duties hereunder. If Richard E. Caruso ("Caruso") is no longer
Chairman of the Board for any reason and, unless Executive agrees in writing not
to serve in such capacity, Executive shall be appointed as Chairman of the
Board.

                  (b) Executive shall devote substantially all his working time,
energy and attention (other than absences due to illness or vacation) to the
performance of his duties hereunder, in a manner that will faithfully and
diligently further the business and interests of Company. Notwithstanding the
above, Executive shall be permitted, to the extent such activities do not impair
the performance by Executive of his duties and responsibilities hereunder or
violate Sections 7.1, 7.2 or 7.3 of this Agreement, to (i) manage Executive's
personal, financial and legal affairs, and (ii) to serve on civic or charitable
boards or committees (it being expressly understood and agreed that Executive's
continuing to serve on any such board and/or committees on which Executive is
serving, or with which Executive is otherwise associated (each of which has been
disclosed to the Company prior to the execution of this Agreement or will be
disclosed promptly thereafter), as of the Commencement Date (as defined below),
shall be deemed not to interfere or conflict with the performance by Executive
of his duties and responsibilities under this Agreement). The Company hereby
agrees to add to the Board one or two chief executive officers of other entities
who are reasonably acceptable to Executive as Board members.

SECTION 2.  TERM OF EMPLOYMENT

              2.1 TERM. The term of Executive's employment hereunder shall
commence on the date hereof (the "Commencement Date") and continue until
December 31, 2005, as further extended or unless sooner terminated in accordance
with the other provisions hereof (the "Term"). Except as hereinafter provided,
on December 31, 2005 and on each subsequent one-year anniversary thereof, the
Term shall be automatically extended for one year unless either party shall have
given to the other party written notice of termination of this Agreement at
least six months prior to such anniversary. If written notice of termination is
given as provided above, Executive's employment under this Agreement shall
terminate on the last day of the then-current Term.

SECTION 3.  COMPENSATION

              3.1 BASIC COMPENSATION. As compensation for Executive's services
during the period from the Commencement Date through December 31, 2001, Company
shall pay to Executive a salary at the annual rate of $325,000, and during the
twelve-month period ending December 31, 2002, the Company shall pay to Executive
a salary at the annual rate of $400,000, in each case payable in periodic
installments in accordance with Company's regular payroll practices in effect
from time to time. Commencing with the twelve-month period ending December 31,
2003 and for each subsequent twelve-month period of Executive's employment
hereunder, Executive's salary shall be in the amount of his annual salary for
the immediately preceding twelve-month period with such increases, if any, as
may be established by the Board, provided that in no event shall Executive's
salary in any such twelve-month period be less than the product of Executive's
salary for the immediately preceding twelve-month period multiplied by a
fraction, the numerator of which is the Consumer Price Index for All Urban
Consumers for all items for the New York metropolitan area (the "CPI") for the
last month in the immediately preceding twelve-month period, and the


                                     -2-



denominator of which is the CPI for January 2002. Executive's annual salary,
as determined in accordance with this Section 3.1, is hereinafter referred to
as his "Base Salary."

                  (b) The Company hereby represents and warrants to Executive

still employed by the Company on December 31, 2005 unless the Additional Unit
Shares shall have been previously delivered to Executive pursuant to Section

prior to such delivery date, to defer such delivery for a period of up to six
years. In the event that Executive's employment is terminated prior to December
31, 2001, the Original Unit Shares shall be delivered to Executive as provided

                  (c) The Company hereby represents and warrants to Executive
that (i) in December 1997 the Company obtained written consent from the holders

SECTION 4.  TERMINATION OF EMPLOYMENT

              4.1 DEATH OF EXECUTIVE. If Executive dies during the Term, Company
shall pay to Executive's estate amounts (including Base Salary, bonuses, expense
reimbursement, etc.) accrued as of the date of Executive's employment
termination (all such accrued amounts as of Executive's employment termination
shall be referred to as "Accrued Obligations") and a lump sum equal to one (1)
times Executive's annual rate of Base Salary. To the extent permitted by the
Company's benefit plans and programs in effect on the date of such termination,
Company shall also provide Executive's spouse and dependents with continued
medical, dental, hospitalization and other health care benefits ("Health
Benefits") (subject to continued contribution, if any, required by such spouse
and dependents for such Health Benefits) for a period of one (1) year from such
termination; provided, that if Executive's spouse or dependents cannot continue
to participate in the Company programs providing such benefits, the Company
shall pay or reimburse any premiums for a health care program for Executive's
spouse and dependents that is


                                     -5-



substantially equivalent to the Company's then-current Health Benefits. Upon
Executive's death, (i) the Original Company Stock Option shall immediately
vest and shall be exercisable until one year following his death, but in no
event beyond December 26, 2007, (ii) the portion of each Additional Company
Stock Option that is vested on the date of his death shall be exercisable
until the later of (a) one year following his death or (b) December 31, 2005,
but in no event beyond December 21, 2010 and (iii) the non-vested portion of
each Additional Company Stock Option shall terminate on the date of his
death. As promptly as practicable following Executive's death, but in no
event later than 90 days following his death, the Original Unit Shares and
the Additional Unit Shares shall be distributed to Executive's estate.

              4.2 DISABILITY OF EXECUTIVE. If Executive, in the reasonable
opinion of a qualified physician jointly selected by Company and Executive (or a
representative of Executive) (a "Qualified Physician"), has been materially
unable to perform his duties hereunder for a period of 180 consecutive days by
reason of physical or mental illness or disability ("Disability"), then the
Board shall have the right to terminate Executive's employment upon 30 days'
prior written notice to Executive at any time during the continuation of such
Disability (a "Disability Termination"). Until a Disability Termination, he
shall continue to receive his full Base Salary and other payments and benefits
hereunder. In the event of a Disability Termination, Company shall not
thereafter be obligated to make any further payments to Executive hereunder
other than (a) Accrued Obligations, (b) the amount that is equal to (x) if such
payments are taxable, then-current Base Salary or, alternatively, (y) if such
payments are not taxable, the after tax equivalent of the then-current Base
Salary, in either case until December 31, 2005, and (c) Health Benefits (subject
to continued contributions required by Executive for such benefits) to the
extent permitted by the Company's benefit plans and programs in effect on the
date of such termination (and the life insurance set forth in Section 3.6(i))
for one (1) year following the Date of Termination (as defined in Section 8.6
herein); PROVIDED, that if Executive, his spouse or his dependents cannot
continue to participate in the Company programs providing Health Benefits, the
Company shall pay or reimburse the premiums for a health care program for
Executive, his spouse and his dependents that is substantially equivalent to the
Company's then-current Health Benefits. Following December 31, 2005, Executive
shall continue to be entitled to receive long-term disability benefits under the
Company's long-term disability program in effect at such time to the extent
Executive is eligible to receive such benefits. In the event of a Disability
Termination, (i) the portion of the Original Company Stock Option that is vested
on the Date of Termination shall be exercisable until one year following the
date of termination, but in no event later than December 26, 2007, (ii) the
portion of each Additional Company Stock Option that is vested on the Date of
Termination shall be exercisable until the later of (a) one year following the
date of termination and (b) December 31, 2005, but in no event later than
December 21, 2010, (iii) the non-vested portions of the Original Company Stock
Option and each Additional Company Stock Option shall terminate on the Date of
Termination and (iv) the Original Unit Shares and the Additional Unit Shares
shall be distributed to Executive as promptly as practicable (but in no event
later than 90 days) following such termination.

              4.3 TERMINATION FOR CAUSE. Executive's employment hereunder shall
terminate immediately upon notice (following satisfaction of the procedures set
forth below) that the Board is terminating Executive for Cause (as defined
herein), in which event Company shall not thereafter be obligated to make any
further payments hereunder other than Accrued Obligations excluding any bonus
accruals. If Executive's employment hereunder is terminated for Cause in
accordance with this Section 4.3 prior to December 31, 2005, (i) the portion of
the Original Company Stock Option that is vested on the Date of Termination
shall be exercisable until December 26, 2007, (ii) the portion of each
Additional Company Stock Option that is vested on the Date of Termination shall
be exercisable until December 21, 2010, (iii) the non-vested portions of the
Original Company Stock Option and each Additional Company Stock Option shall
terminate on the Date of Termination and (iv) the Additional Unit Shares shall
be distributed to Executive on January 1, 2010. In addition, if the Executive's
employment is terminated for Cause in


                                    -6-



accordance with this Section 4.3 prior to December 31, 2001, the Original
Unit Shares shall be distributed to Executive on January 1, 2018. "Cause"
shall be limited to the following:

                  (i) willful and continued failure to use reasonable best
efforts to substantially perform his duties as President and Chief Executive
Officer (other than such failure resulting from Executive's physical or mental
illness, in the reasonable opinion of a Qualified Physician, or the failure of
Executive to perform such duties during the remedy period set forth in Section
4.4(b) hereof following the issuance of a Notice of Termination by Executive for
Good Reason, unless an arbitration panel finds Executive to have acted in bad
faith in issuing such Notice of Termination) after demand for substantial
performance is delivered by the Company in writing that specifically identifies
the manner in which the Company believes Executive has not used reasonable best
efforts to substantially perform his duties;

                  (ii) willful misconduct that is materially and demonstrably
injurious to the Company or any of its subsidiaries; or

                  (iii) conviction or plea of guilty or NOLO CONTENDERE to a
felony or to any other crime involving moral turpitude which conviction or plea
is materially and demonstrably injurious to the Company or any of its
subsidiaries.

For purposes of this Section 4.3, no act, or failure to act, by Executive shall
be considered "willful" unless committed in bad faith, giving due consideration
to Executive's duties and status as President and Chief Executive Officer of the
Company, and without a reasonable belief that the act or omission was in the
best interests of the Company or any of its subsidiaries. Cause shall not exist
under this Section 4.3 unless and until the Company has delivered to Executive a
copy of a resolution duly adopted by a majority of the Board (excluding
Executive for purposes of determining such majority) at a meeting of the Board
called and held for such purpose (after reasonable, but in no event less than
ten (10) days' notice, to Executive and an opportunity for Executive, together
with his counsel, to be heard before the Board), finding that in the good faith
opinion of the Board, Executive was guilty of the conduct set forth in this
Section 4.3 and specifying the particulars thereof in detail. This Section 4.3
shall not prevent Executive from challenging in any court of competent
jurisdiction the Board's determination that Cause exists or that Executive has
failed to cure any act (or failure to act) that purportedly formed the basis for
the Board's determination. The Company must provide notice to Executive that it
is intending to terminate his employment for Cause within one hundred and twenty
(120) days after the Company has knowledge of the occurrence of the event it
believes constitutes Cause.

If, prior to December 31, 2005, Executive voluntarily leaves his employment with
the Company (other than for Good Reason (as defined in Section 4.4(b)) or due to
Disability), such voluntary leaving shall not be treated as a breach of this
Agreement by Executive and shall not give rise to a claim by the Company for
monetary damages, but shall be treated as if it were a termination for Cause
under this Section 4.3.


                                      -7-



              4.4 TERMINATION WITHOUT CAUSE OR BY EXECUTIVE FOR GOOD REASON.

                  (a) If (i) Executive's employment is terminated by the Company
for any reason other than Cause or the death or Disability Termination of
Executive, or (ii) Executive's employment is terminated by Executive for Good
Reason (as defined herein), then (A) the Company shall pay to Executive a lump
sum cash payment equal to the sum of (x) the Accrued Obligations and (y) his
Base Salary (including the minimum increases provided therein) during the
remainder of the then-current Term, (B) the Original Company Stock Option
granted to Executive shall become immediately vested on the date of such
termination and shall be exercisable through December 26, 2007, (C) each
Additional Company Stock Option granted to Executive shall become immediately
vested on the date of such termination and shall be exercisable through December
21, 2010 and (D) the Original Unit Shares and the Additional Unit Shares shall
be delivered to Executive as soon as practicable (but in no event later than 90
days) following such termination. Further, the Company shall maintain in full
force and effect for the continued benefit of Executive, his spouse and his
dependents for the remaining balance of the Term the Health Benefits and life
insurance programs (including, without limitation, the insurance set forth in
Section 3.5(i)) in which Executive, his spouse and his dependents were
participating immediately prior to the date of such termination at the level in
effect and upon substantially the same terms and conditions (including without
limitation contributions required by Executive for such benefits) as existed
immediately prior to the date of termination; provided, that if Executive, his
spouse or his dependents cannot continue to participate in the Company programs
providing such benefits, the Company shall pay or reimburse the premiums for a
health care program for Executive, his spouse and his dependents that is
substantially equivalent to the then-current Health Benefits; but further
provided, that such Health Benefits shall terminate upon the date or dates
Executive receives equivalent coverage and benefits that do not include waiting
period or pre-existing condition limitations, under the plans and programs of a
subsequent employer (such coverage and benefits to be determined on a
coverage-by-coverage or benefit-by-benefit basis).

                  (b) "Good Reason" shall mean the following, provided that
Executive shall have given written notice thereof to the Company within one
hundred and twenty (120) days after Executive has knowledge of the occurrence of
the event he believes constitutes Good Reason, and the Company shall have failed
to remedy the circumstances within 90 days after receipt of such notice (or
acknowledges in writing that Good Reason will not be remedied), except in the
case of (iv) and (x) below, in which case the remedy period shall be 15 days,
and (viii) below, in which case the remedy period shall be five days :

                  (i) material breach of the Company's obligations hereunder;

                  (ii) any decrease in Executive's salary as increased during
the Term (except for decreases that are in conjunction with decreases in
executive salaries generally) or a failure by the Company to pay any such
amounts when due or any amounts due under Sections 3.1 and 3.4 or the assignment
to Executive of duties and/or responsibilities inconsistent with his status as
President and Chief Executive Officer of the Company, or a material diminution
in the nature of Executive's duties and/or responsibilities, reporting
obligations, titles or authority, or the removal of Executive from the Board;

                  (iii) the failure of Executive to be appointed to the
positions set forth in Section 1.2(a) or to be appointed as a member of the
Board;

                  (iv) the relocation by the Company of Executive's office
location to a location more than thirty (30) miles from Princeton, New Jersey,
or sixty (60) miles from New York, New York;


                                     -8-



                  (v) the Company's material breach of the 1996 Plan, the 1999
Plan, the 2000 Plan, the Original Company Stock Option, either Additional
Company Stock Option, the Original Restricted Units Agreement or the Additional
Restricted Units Agreement;

                  (vi) the Company's material failure to provide the benefits
set forth in Sections 3.5 and 3.6 or the failure of the Company to substantially
provide any material employee benefits due to be provided to Executive (other
than any such failure not inconsistent with any express provisions contained
herein which failure affects all senior executive officers);

                  (vii) the Company's failure to provide in all material
respects the indemnification set forth in Section 7.7 of this Agreement;

                  (viii) the failure of any successor in interest of the Company
to become bound by the terms of this Agreement in accordance with Section 8.4
below;

                  (ix) Caruso is no longer serving as the Chairman of the
Company and, unless otherwise agreed to in writing by Executive, Executive is
not appointed to that position; and

                  (x) the Company's failure, after notice from Executive, to
initiate the procedures, as soon as practicable, to establish and maintain the
registration statements provided for in the Original Registration Rights
Provisions and EXHIBIT B hereto.

Executive's right to terminate his employment hereunder for Good Reason shall
not be affected by his Disability. Subject to compliance by Executive with the
notice provisions of this Section 4.4(b), Executive's continued employment prior
to terminating employment for Good Reason shall not constitute consent to, or a
waiver of rights with respect to, any act or failure to act constituting Good
Reason. In the event Executive delivers to the Company a notice of termination
for Good Reason, Executive agrees to appear before a meeting of the Board called
and held for such purpose (after reasonable notice, but no more than ten days
(or four days under (viii) above) at Executive's election) and specify to the
Board the particulars as to why Executive believes adequate grounds for
termination for Good Reason exist. No action by the Board, other than the remedy
of the circumstances within the time periods specified by the first sentence of
Section 4.4(b), shall be binding on Executive.

No termination of Executive without Cause shall be effective unless such
termination is in writing pursuant to action by a majority of the Board at a
properly constituted meeting thereof.

              4.5 FAILURE TO EXTEND. A failure to extend this Agreement pursuant
to Section 2.1 by either party shall not be treated as a termination of
Executive's employment for purposes of this Agreement.

              4.6 MITIGATION.

                  (a) Executive shall not be required to mitigate amounts
payable under this Section 4 by seeking other employment or otherwise, and there
shall be no offset against amounts due Executive under this Agreement on account
of subsequent employment except as specifically provided herein.

                  (b) Amounts owed to Executive under this Agreement, the
Original Restricted Units Agreement or the Additional Restricted Units Agreement
shall not be offset by any claims the Company may have against Executive (other
than an offset for any due and payable loan amount under Section 3.7 and any
good faith liquidated dollar claim with respect to a breach of this Agreement)
and, except with respect to such loan amount and any good faith liquidated
dollar claim as set forth above, the


                                     -9-



Company's obligation to make the payments provided for in this Agreement, the
Original Company Stock Option Agreement, each Additional Company Stock Option
Agreement, the Original Registration Rights Provisions, the Additional
Registration Rights Provisions, the Original Restricted Units Agreement and
the Additional Restricted Units Agreement, and otherwise to perform its
obligations hereunder and under such agreements, shall not be affected by any
other circumstances, including, without limitation, any counterclaim,
recoupment, defense or other right which the Company may have against
Executive or others.

Business Combination (as defined in Section 6.1(c) hereof) in which the Company
is not the surviving corporation and (C) the date that the Company has
outstanding greater than 45,000,000 shares of Common Stock (appropriately
adjusted for stock splits, stock dividends, reclassifications and other similar
changes in the capital structure of the Company after the date hereof)
calculated on a fully-diluted basis after giving effect to all outstanding
options, warrants, rights and other securities convertible into or exercisable
for Common Stock of the Company.

                  "Triggering Event" shall mean either a Qualifying Disposition
or a Change in Control.

                  (b) Unless Executive has been terminated for Cause in
accordance with Section 4.3 hereof or has voluntarily left his employment with
the Company (other than for Good Reason or due to Disability), in each case
prior to December 31, 2005, upon the occurrence of a Change in Control each
Additional Company Stock Option shall vest and be exercisable through December
21, 2010 and, notwithstanding any notice of deferral delivered by Executive to
the Company pursuant to Section 3.3(a) hereof, the Additional Unit Shares shall,
at the election of Executive by written notice to the Company, be


                                     -10-



distributed to Executive at such time or times as specified by Executive in
such notice (which may include the date immediately prior to such Change in
Control).

SECTION 6.  CHANGE IN CONTROL

              6.1 DEFINITION OF CHANGE IN CONTROL. A "Change in Control" of the
Company shall be deemed to have occurred:

                  (a) if the "beneficial ownership" (as defined in Rule 13d-3
under the Securities Exchange Act of 1934) of securities representing more than
fifty percent (50%) of the combined voting power of the Company Voting
Securities (as herein defined) is acquired by any individual, entity or group (a
"Person"), other than Caruso (or any entity controlled by Caruso), the Company,
any trustee or other fiduciary holding securities under any employee benefit
plan of the Company or an affiliate thereof, or any corporation owned, directly
or indirectly, by the stockholders of the Company in substantially the same
proportions as their ownership of stock of the Company (for purposes of this
Agreement, "Company Voting Securities" shall mean the then outstanding voting
securities of the Company entitled to vote generally in the election of
directors); PROVIDED, however, that any acquisition from the Company or any
acquisition pursuant to a transaction which complies with clauses (i), (ii) and
(iii) of paragraph (c) of this Section 6.1 shall not be a Change in Control
under this paragraph (a); or

                  (b) if individuals who, as of the date hereof, constitute the
Board (the "Incumbent Board") cease for any reason to constitute at least a
majority of the Board; provided, however, that any individual becoming a
director subsequent to the date hereof whose election, or nomination for
election by the Company's stockholders, was approved by a vote of at least a
majority of the directors then comprising the Incumbent Board shall be
considered as though such individual were a member of the Incumbent Board, but
excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of an actual or threatened election contest with
respect to the election or removal of directors or other actual or threatened
solicitation of proxies or consents by or on behalf of a Person other than the
Board; or

                  (c) upon consummation by the Company of a reorganization,
merger or consolidation or sale or other disposition of all or substantially all
of the assets of the Company or the acquisition of assets or stock of another
entity (a "Business Combination"), in each case, unless immediately following
such Business Combination; (i) more than 50% of the combined voting power of the
then outstanding voting securities entitled to vote generally in the election of
directors of (x) the corporation resulting from such Business Combination (the
"Surviving Corporation"), or (y) if applicable, a corporation which as a result
of such transaction owns the Company or all or substantially all of the
Company's assets either directly or through one or more subsidiaries (the
"Parent Corporation"), is represented, directly or indirectly, by Company Voting
Securities outstanding immediately prior to such Business Combination (or, if
applicable, is represented by shares into which such Company Voting Securities
were converted pursuant to such Business Combination), and such voting power
among the holders thereof is in substantially the same proportions as their
ownership, immediately prior to such Business Combination, of the Company Voting
Securities, (ii) no Person (excluding any employee benefit plan (or related
trust) of the Company or such corporation resulting from such Business
Combination) beneficially owns, directly or indirectly, 50% or more of the
combined voting power of the then outstanding voting securities eligible to
elect directors of the Parent Corporation (or, if there is no Parent
Corporation, the Surviving Corporation) except to the extent that such ownership
of the Company existed prior to the Business Combination and (iii) at least a
majority of the members of the board of directors of the Parent Corporation (or,
if there is no Parent Corporation, the Surviving Corporation) were members of
the Incumbent Board at the time of the execution of the initial agreement, or
the action of the Board, providing for such Business Combination; PROVIDED that
a Business


                                     -11-



Combination that is a tax-free stock for stock merger between the Company and
another entity shall not be treated as a Change in Control if Executive is
the chief executive officer of the surviving public entity of such Business
Combination immediately following its consummation, and such surviving entity
remains publicly traded on a national securities exchange or on the NASDAQ
(an "Exempt Business Combination"); or

                  (d) upon approval by the stockholders of the Company of a
complete liquidation or dissolution of the Company.

              6.2 GROSS-UP.

                  (a) Anything in this Agreement to the contrary
notwithstanding, in the event it shall be determined that any payment, award,
benefit or distribution (or any acceleration of any payment, award, benefit or
distribution) by the Company (or any of its affiliated entities) to or for the
benefit of Executive (a "Payment") would be subject to the excise tax imposed by
Section 4999 of the Code or any corresponding provisions of state or local tax
laws, or any interest or penalties are incurred by Executive with respect to
such excise tax (such excise tax, together with any such interest and penalties,
are hereinafter collectively referred to as the "Excise Tax"), then Executive
shall be entitled to receive an additional payment (a "Gross-Up Payment") in an
amount such that after payment by Executive of all taxes (including any interest
or penalties imposed with respect to such taxes), including, without limitation,
any income taxes (and any interest and penalties imposed with respect thereto)
and Excise Tax imposed upon the Gross-Up Payment, Executive retains an amount of
the Gross-Up Payment equal to the Excise Tax imposed upon the Payments. The
payment of a Gross-Up Payment shall not be conditioned upon the occurrence of a
termination of employment.

                  (b) Subject to the provisions of Section 6.2(a), all
determinations required to be made under this Section 6.2, including whether and
when a Gross-Up Payment is required and the amount of such Gross-Up Payment and
the assumptions to be utilized in arriving at such determination, shall be made
by the Company's independent accounting firm as of immediately prior to the
Change in Control (the "Accounting Firm"), which shall provide detailed
supporting calculations both to the Company and Executive within fifteen (15)
business days of the receipt of notice from Executive that there has been a
Payment, or such earlier time as is requested by the Company. In the event that
the Accounting Firm is serving as accountant or auditor for the individual,
entity or group effecting the Change in Control, the Company shall appoint
another nationally recognized accounting firm to make the determinations
required hereunder (which accounting firm, if reasonably acceptable to
Executive, shall then be referred to as the Accounting Firm hereunder). All fees
and expenses of the Accounting Firm shall be borne solely by the Company. Any
Gross-Up Payment, as determined pursuant to this Section 6.2, shall be paid by
the Company to Executive within five (5) days of receipt of the Accounting
Firm's determination. Any determination by the Accounting Firm shall be binding
upon the Company and Executive. As a result of the uncertainty in the
application of Section 4999 of the Code at the time of the initial determination
by the Accounting Firm hereunder, it is possible that Gross-Up Payments which
will not have been made by the Company should have been made ("Underpayment"),
consistent with the calculations required to be made hereunder. In the event
that Executive thereafter is required to make a payment of any Excise Tax (or
any additional Excise Tax), the Accounting Firm shall determine the amount of
the Underpayment that has occurred and any such Underpayment shall be promptly
paid by the Company to or for the benefit of Executive. In the event of any
claim by the Internal Revenue Service for any Excise Tax or additional Excise
Tax, the Company shall have the right to control the defense of such claim and
Executive shall cooperate and assist the Company in connection therewith as
reasonably requested by the Company; provided that all expenses of such claim
(including any additional interest or penalties) shall be paid by the Company,
and the Company shall indemnify and hold the Executive harmless, on an after-tax
basis, for any


                                    -12-



Excise Tax or income tax (including any interests and penalties) imposed as a
result of such representation and payment of costs and expenses. In addition,
Executive will cooperate as reasonably requested by the Company with the
Company in making any refund claim for any Excise Tax already paid, and any
refunds of any such tax (or any Gross-Up Payments or other payments made by
the Company in respect thereof) obtained by the Executive shall be promptly
returned to the Company.

                  If the Company directs the Executive to pay such claim and sue
for a refund, the Company shall advance the amount of such payment to the
Executive, on an interest-free basis and shall indemnify and hold the Executive
harmless, on an after-tax basis, from any Excise Tax or income tax (including
interest or penalties with respect thereto) imposed with respect to such advance
or with respect to any imputed income with respect to such advance; and further
provided that any extension of the statute of limitations relating to payment of
taxes for the taxable year of the Executive with respect to which such contested
amount is claimed to be due is limited solely to such contested amount.
Furthermore, the Company's control of the contest shall be limited to issues
with respect to which a Gross-Up Payment would be payable hereunder and the
Executive shall be entitled to settle or contest, as the case may be, any other
issue raised by the Internal Revenue Service or any other taxing authority.

SECTION 7.  RESTRICTIVE COVENANTS

              7.1 CONFIDENTIALITY. Executive acknowledges a duty of
confidentiality owed to Company and shall not, at any time during or after his
employment by Company, retain in writing, use, divulge, furnish, or make
accessible to anyone, without the express authorization of the Board, any trade
secret, private or confidential information or knowledge of Company obtained or
acquired by him while so employed. All computer software, business cards,
telephone lists, customer lists, price lists, contract forms, catalogs, Company
books, records, files and know-how acquired while an employee of Company are
acknowledged to be the property of Company and shall not be duplicated, removed
from Company's possession or premises or made use of other than in pursuit of
Company's business or as may otherwise be required by law or any legal process,
or as is necessary in connection with any adversarial proceeding against the
Company and, upon termination of employment for any reason, Executive shall
deliver to Company, without further demand, all copies thereof which are then in
his possession or under his control. No information shall be treated as
"confidential information" if it is generally available public knowledge at the
time of disclosure or use by Executive.

              7.2 INVENTIONS AND IMPROVEMENTS. Executive shall promptly
communicate to Company all ideas, discoveries and inventions which are or may be
useful to Company or its business. Executive acknowledges that all such ideas,
discoveries, inventions, and improvements which heretofore have been or are
hereafter made, conceived, or reduced to practice by him at any time during his
employment with Company heretofore or hereafter gained by him at any time during
his employment with Company are the property of Company, and Executive hereby
irrevocably assigns all such ideas, discoveries, inventions, and improvements to
Company for its sole use and benefit, without additional compensation. The
provisions of this Section 7.2 shall apply whether such ideas, discoveries,
inventions, or improvements were or are conceived, made or gained by him alone
or with others, whether during or after usual working hours, whether on or off
the job, whether applicable to matters directly or indirectly related to
Company's business interests (including potential business interests), and
whether or not within the specific realm of his duties. Executive shall, upon
request of Company, but at no expense to Executive, at any time during or after
his employment with Company, sign all instruments and documents reasonably
requested by Company and otherwise cooperate with Company to protect its right
to such ideas, discoveries, inventions, or improvements including applying for,
obtaining, and enforcing patents and copyrights thereon in such countries as
Company shall determine.


                                     -13-



              7.3 NONCOMPETITION. For a period of two (2) years following the
Date of Termination of Executive's employment (other than a termination under
Section 4.4(a) or the expiration of the Term), or for a period of one (1) year
following the expiration of the Term, Executive shall not directly or
indirectly: (i) engage, anywhere within the geographical areas in which the
Company is conducting business operations or providing services as of the date
of Executive's termination of employment, in the tissue engineering business
(the use of implantable absorbable materials, with or without a bioactive
component, to attempt to elicit a specific cellular response in order to
regenerate tissue or to impede the growth of tissue or migration of cells) (the
"Tissue Engineering Business") or in any business the revenues of which
constituted at least 30% of the Company's revenues during the six (6) month
period prior to the Date of Termination (together with the Tissue Engineering
Business, the "Business"); (ii) be or become a stockholder, partner, owner,
officer, director or employee or agent of, or a consultant to or give financial
or other assistance to, any person or entity engaged in the Business; (iii) seek
in competition with the business of Company to procure orders from or do
business with any customer of Company; (iv) solicit, or contact with a view to
the engagement or employment by any person or entity of, any person who is an
employee of Company; (v) seek to contract with or engage (in such a way as to
adversely affect or interfere with the business of Company) any person or entity
who has been contracted with or engaged to manufacture, assemble, supply or
deliver products, goods, materials or services to Company; or (vi) engage in or
participate in any effort or act to induce any of the customers, associates,
consultants, or employees of Company to take any action which might be
disadvantageous to Company; provided, however, that nothing herein shall
prohibit Executive and his affiliates from owning, as passive investors, in the
aggregate not more than 5% of the outstanding publicly traded stock of any
corporation so engaged; and provided, further, that Executive shall not be
prohibited from (1) making any investment in, being or becoming a partner,
owner, officer, director or employee or agent of, or consultant to, or give
financial or other assistance to, any business enterprise (including, without
limitation, any investment or venture capital fund or investment bank) that
makes or has made any investment in or that provides advisory, financing or
underwriting services to any Person or entity engaged in the Business provided
that Executive does not render services (whether as an employee, consultant,
advisor or otherwise) to the division or portion of such person or entity
engaged in the Business or (2) rendering services (including under (1) above) to
an entity conducting its business operations or providing services in the
Business, if such entity is diversified and Executive does not render services,
directly or indirectly, to the division or portion of the entity which is
conducting its business operations or providing services in the Business.
Executive shall not be prevented from engaging in the activities set forth in
(i) through (vi) above if he terminates employment or his employment is
terminated, in each case in accordance with Section 4.4(a) of this Agreement.

              7.4 INJUNCTIVE AND OTHER RELIEF.

                  (a) Executive acknowledges and agrees that the covenants
contained herein are fair and reasonable in light of the consideration paid
hereunder, and that damages alone shall not be an adequate remedy for any breach
by Executive of his covenants contained herein and accordingly expressly agrees
that, in addition to any other remedies which Company may have, Company shall be
entitled to injunctive relief in any court of competent jurisdiction for any
breach or threatened breach of any such covenants by Executive. Nothing
contained herein shall prevent or delay Company from seeking, in any court of
competent jurisdiction, specific performance or other equitable remedies in the
event of any breach or intended breach by Executive of any of its obligations
hereunder.

                  (b) Notwithstanding the equitable relief available to Company,
Executive, in the event of a breach of his covenants contained in Section 7
hereof, understands and agrees that the uncertainties and delay inherent in the
legal process would result in a continuing breach for some period of time, and
therefore, continuing injury to Company until and unless Company can obtain such
equitable relief. Therefore, in addition to such equitable relief, Company shall
be entitled to monetary damages for


                                      -14-



any such period of breach until the termination of such breach, in an amount
up to the amount of all monies received by Executive as a result of said
breach. If Executive should use or reveal to any other person or entity any
confidential information, such use or revelation would be considered a
continuing violation on a daily basis for as long as such confidential
information is made use of by Executive.

                  (c) If any provision of Section 7 is determined to be invalid
or unenforceable by reason of its duration or scope, such duration or scope, or
both, shall be deemed to be reduced to a duration or scope to the extent
necessary to render such provision valid and enforceable. In such event,
Executive shall negotiate in good faith to provide Company with lawful and
enforceable protection that is most nearly equivalent to that found to be
invalid or unenforceable.

              7.5 DEFINITION OF "COMPANY." "Company" as used in Section 7
includes all majority-owned subsidiaries of Company.

              7.6 CONTINUING OPERATION. Except as specifically provided in this
Section 7, the termination of Executive's employment or of this Agreement shall
have no effect on the continuing operation of this Section 7.

              7.7 INDEMNIFICATION. Executive shall be entitled to
indemnification in accordance with the Company's by-laws in effect on the date
hereof and to the fullest extent permitted under Delaware law.

SECTION 8.  MISCELLANEOUS

              8.1. ARBITRATION. Any dispute or controversy arising under or in
connection with this Agreement, other than injunctive relief sought under
Section 7.4 above, shall be settled exclusively by arbitration in Wilmington,
Delaware, in accordance with the Commercial Arbitration Rules of the American
Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction. Executive shall be entitled
to recover from the Company the amount of his legal fees (and related expenses)
in excess of $50,000 in the aggregate in connection with claims or disputes
under this Agreement, the Original Company Stock Option, each Additional Company
Stock Option, the registration statements provided for in the Original
Registration Rights Provisions and EXHIBIT B hereto, the Original Restricted
Units Agreement and the Additional Restricted Units Agreement, unless Executive
is determined by the arbitrator or a court to have acted frivolously or in bad
faith with respect to such claim or dispute. The reimbursement shall be made as
soon as practicable following the resolution of such contest or dispute (whether
or not appealed) to the extent the Company receives reasonable written evidence
of such fees and expenses.

              8.2. PRIOR EMPLOYMENT. Executive represents and warrants that his
acceptance of employment at Company and his execution of this Agreement and the
Prior Employment Agreement has not breached, and the performance of his duties
hereunder and thereunder will not and did not breach, any obligation owed by him
to, or any agreement with, any prior employer or any other person.

              8.3. KEY EMPLOYEE INSURANCE. Company shall have the right at its
expense to purchase insurance on the life of Executive, in such amounts as it
shall from time to time determine, of which Company shall be the beneficiary.
Executive shall submit to such physical examinations as may reasonably be
required and shall otherwise cooperate with Company in obtaining such insurance.


                                      -15-



              8.4. ASSIGNMENT; BENEFIT. This Agreement shall not be assignable
by Executive, other than his rights to payments or benefits hereunder, which may
be transferred only by will or the laws of descent and distribution. Upon
Executive's death, this Agreement and all rights of Executive hereunder shall
inure to the benefit of and be enforceable by Executive's beneficiary or
beneficiaries, personal or legal representatives, or estate, to the extent any
such person succeeds to Executive's interests under this Agreement. No rights or
obligations of the Company under this Agreement may be assigned or transferred
except that the Company will require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or assets of the Company to expressly assume and agree to
perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had taken place.
As used in this Agreement, "Company" shall mean the Company as hereinbefore
defined and any successor to its business and/or assets (by merger, purchase or
otherwise) which executes and delivers the agreement provided for in this
Section 8.4 or which otherwise becomes bound by all the terms and provisions of
this Agreement by operation of law.

              8.5 NOTICES. All notices hereunder shall be in writing and shall
be sufficiently given if hand-delivered, sent by documented overnight delivery
service or registered or certified mail, postage prepaid, return receipt
requested or by telegram or telefax (confirmed by U.S. mail), receipt
acknowledged, addressed as set forth below or to such other person and/or at
such other address as may be furnished in writing by any party hereto to the
other. Any such notice shall be deemed to have been given as of the date
received, in the case of personal delivery, or on the date shown on the receipt
or confirmation therefor, in all other cases. Any and all service of process and
any other notice in any such action, suit or proceeding shall be effective
against any party if given as provided in this Agreement; provided that nothing
herein shall be deemed to affect the right of any party to serve process in any
other manner permitted by law.

                  8.6      TERMINATION PROCEDURES.


              (a) Any termination of Executive's employment by the Company or by
Executive during the Term (other than termination pursuant to death) shall be
communicated by written Notice of Termination to the other party hereto in
accordance with Section 8.5. For purposes of this Agreement, a "Notice of
Termination" shall mean a notice which shall indicate the specific termination
provision in this Agreement relied upon and shall set forth in reasonable detail
the facts and circumstances claimed to provide a basis for termination of
Executive's employment under the provision so indicated.


                                     -16-



              (b) "Date of Termination" shall mean (i) if Executive's employment
is terminated by his death, the date of death, (ii) if Executive's employment is
terminated pursuant to Section 4.2, thirty (30) days after Notice of Termination
(provided that Executive shall not have returned to the substantial performance
of his duties on a full-time basis during such thirty (30) day period), or (iii)
if Executive's employment is terminated for any other reason, the date on which
a Notice of Termination is given or any later date (within thirty (30) days
after the giving of such notice) set forth in such Notice of Termination;
provided that in the event of a termination for Good Reason, the Date of
Termination shall not be prior to the expiration of any remedy period with
respect to Good Reason in Section 4.4(b).

              8.7 ENTIRE AGREEMENT AND MODIFICATION; WAIVER. This Agreement
constitutes the entire agreement between the parties hereto with respect to the
matters contemplated herein and supersedes all prior agreements and
understandings with respect thereto, including without limitation the Prior
Employment Agreement which is hereby terminated; PROVIDED, that nothing herein
shall affect the validity or enforceability of the Original Company Stock
Option, the Original Restricted Units Agreement (and the Original Restricted
Units evidenced thereby) or the Original Registration Rights Provisions, each of
which is in full force and effect on the date hereof (provided that all
references in the Original Restricted Units Agreement and the Original Company
Stock Option to "Employment Agreement" shall hereafter mean this Agreement and
not the Prior Employment Agreement). No amendment, modification, or waiver of
this Agreement shall be effective unless in writing. Neither the failure nor any
delay on the part of any party to exercise any right, remedy, power or privilege
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, remedy, power or privilege preclude any other or further
exercise of the same or of any other right, remedy, power, or privilege with
respect to such occurrence or with respect to any other occurrence.

              8.8 GOVERNING LAW. This Agreement is made pursuant to, and shall
be construed and enforced in accordance with, the laws of the State of Delaware
and the federal laws of the United States of America, to the extent applicable,
without giving effect to otherwise applicable principles of conflicts of law.

              8.9 WITHHOLDING. All payments hereunder shall be subject to any
required withholding of Federal, state and local taxes pursuant to any
applicable law or regulation.

              8.10 HEADINGS; COUNTERPARTS. The headings of paragraphs in this
Agreement are for convenience only and shall not affect its interpretation. This
Agreement may be executed in two or more counterparts, each of which shall be
deemed to be an original and all of which, when taken together, shall be deemed
to constitute the same Agreement.

              8.11 FURTHER ASSURANCES. Each of the parties hereto shall execute
such further instruments and take such other actions as the other party shall
reasonably request in order to effectuate the purposes of this Agreement.

              8.12 SHAREHOLDER APPROVAL. The Company represents and warrants to
Executive that no shareholder approval is required for the Company to enter into
this Agreement (or the Prior Employment Agreement) and provide the benefits
hereunder (or thereunder), or that such shareholder approval has been obtained.

              8.13 NONCONTRAVENTION. The Company represents that the Company is
not prevented from entering into or performing this Agreement by the terms of
any law, order, rule or regulation, its by-laws or certificate of incorporation,
or any agreement to which it is a party, other than which would not have a
material adverse effect on the Company's abilities to enter into or perform this
Agreement.


                                      -17-



              8.14 SURVIVORSHIP. The respective rights and obligations of the
Company and Executive hereunder shall survive any termination of this Agreement
or Executive's employment to the extent necessary for the intended preservation
of such rights and obligations.

              8.15 VALIDITY. The invalidity or enforceability of any provision
or provisions of this Agreement shall not affect the validity or enforceability
of any other provision of this Agreement, which shall remain in force and
effect.

              IN WITNESS WHEREOF, the parties have executed this Agreement as of
the date first above written.

                                                                  EXHIBIT 10.2

                     REGISTRATION UNDER THE SECURITIES ACT.

     1.   REGISTRATION FOR REGISTRABLE SECURITIES UNDERLYING OPTIONS OR UNITS.
          The Company agrees to file a "shelf" registration statement, providing
          for the registration of, and the sale on a continuous or delayed basis
          by the Executive in accordance with the methods of distribution
          specified by the Executive and consistent with the terms and
          provisions hereof, of Registrable Securities (as defined in Paragraph
          6 hereof) pursuant to Rule 415 under the Securities Act of 1933, as
          amended (the "Securities Act"), and/or any similar rule that may be
          adopted by the Securities and Exchange Commission (the "Commission")
          as soon as practicable following the request of the Executive, and to
          use its commercially reasonable best efforts to cause such
          registration statement to be declared effective by the Commission
          under the Securities Act as soon as practicable following such filing.
          The Company further agrees to use its commercially reasonable best
          efforts to maintain the effectiveness of such registration statement
          or registration statements until the securities registered thereunder
          cease to be Registrable Securities.

     2.   REGISTRATION PROCEDURES. In connection with any shelf registration
          statement contemplated hereby, the following provisions shall apply:

              (a) The Company shall furnish to the Executive, prior to the
filing thereof with the Commission, a copy of such shelf registration statement
and each amendment thereto and each amendment or supplement, if any, to the
prospectus included therein and, subject to Paragraph 1 above, shall use its
best efforts to reflect in each such document, when so filed with the
Commission, such comments as the Executive reasonably may propose; provided,
however, that the Company shall not be obligated to include in any such shelf
registration statement, prospectus, prospectus supplement or amendment to such
shelf registration statement any requested information that is unreasonable in
scope taking into account the Company's most recent prospectus or prospectus
supplement used in connection with a primary or secondary offering of equity
securities by the Company and the Company's periodic reports under the
Securities Exchange Act of 1934, as amended (the "Exchange Act").

              (b) The Company shall take such action as may be necessary so that
(i) such shelf registration statement and any amendment thereto and any
prospectus forming part thereof and any amendment or supplement thereto (and
each report or other document incorporated therein by reference in each case)
complies in all material respects with the Securities Act, the Exchange Act and
the respective rules and regulations thereunder, (ii) such shelf registration
statement and any amendment thereto does not, when it becomes effective, contain
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
and (iii) such prospectus forming part of any shelf registration statement, and
any amendment or supplement to such prospectus, does not include an untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements, in the light of the circumstances under which they were
made, not misleading.

              (c) The Company shall advise the Executive:

              (i) when such shelf registration statement and any amendment
       thereto has been filed with the Commission and when such shelf
       registration statement or any post-effective amendment thereto has become
       effective;


                                     -1-



              (ii) of any request by the Commission for amendments or
       supplements to such shelf registration statement or the prospectus
       included therein or for additional information.

              (iii) of the issuance by the Commission of any stop order
       suspending effectiveness of such shelf registration statement or the
       initiation of any proceedings for that purpose;

              (iv) of the receipt by the Company of any notification with
       respect to the suspension of the qualification of the securities included
       in such shelf registration statement for sale in any jurisdiction or the
       initiation of any proceeding for such purpose; and

              (v) upon the receipt of a Request for Sale under paragraph 2(f),
       of the existence of any circumstances or the happening of any events that
       would require the making of any changes in such shelf registration
       statement or the prospectus so that, as of such date, such shelf
       registration statement and the prospectus would not contain an untrue
       statement of a material fact and would not omit to state a material fact
       required to be stated therein or necessary to make the statements therein
       (in the case of the prospectus, in light of the circumstances under which
       they were made) not misleading (which advice shall be accompanied by an
       instruction to suspend the use of the prospectus until the requisite
       changes have been made).

              (d) The Company shall use its commercially reasonable best efforts
to prevent the issuance, and if issued to obtain the withdrawal, of any order
suspending the effectiveness of such shelf registration statement at the
earliest possible time.

              (e) The Company shall furnish to the Executive, without charge, as
many copies of the prospectus (including each preliminary prospectus) included
in such shelf registration statement and any amendment or supplement thereto as
the Executive may reasonably request; and the Company consents (except during
the continuance of any event described in Paragraph 2(c)(iii), (iv) (limited to
the jurisdiction of such suspension) or (v) above) to the use of the prospectus
and any amendment or supplement thereto by the Executive in connection with the
offering and sale of the Registrable Securities covered by the prospectus and
any amendment or supplement thereto until such time as the Securities so covered
cease be Registrable Securities.

              (f) The Executive shall notify the Company in writing of his
intention to sell securities registered pursuant to any registration statement
filed pursuant to Paragraph 1 above (any such notice, a "Request for Sale") not
less than 10 days prior to the proposed Trade Date of any such sale, which
Request for Sale shall include a request from the Executive or (if applicable) a
managing underwriter to prepare and file an amendment or supplement to such
shelf registration statement or the prospectus contained therein. "Trade Date"
shall mean the date the Executive enters into any underwriting, agency or other
purchase agreement or understanding for the sale of, or otherwise agrees to
sell, securities registered pursuant to such registration statement. No such
notification shall obligate the Executive to consummate any such sale.

              (g) Prior to any offering of Registrable Securities pursuant to
such shelf registration statement, the Company shall register or qualify or
cooperate with the Executive in connection with the registration or
qualification of such Registrable Securities for offer and sale under the
securities or blue sky laws of such jurisdictions as the Executive reasonably
requests in writing and do any and all other acts or things necessary or
advisable to enable the offer and sale in such jurisdictions of the Registrable
Securities covered by such shelf registration statement; provided, however, that
in no event shall the Company be obligated to (i) qualify as a foreign


                                      -2-




corporation or as a dealer in securities in any jurisdiction where it would not
otherwise be required to so qualify but for this Paragraph 2(g) or (ii) file any
general consent to service of process in any jurisdiction where it is not as of
the date hereof so subject.

              (h) The Company shall cooperate with the Executive to facilitate
the timely preparation and delivery of certificates representing Registrable
Securities to be sold pursuant to such shelf registration statement free of any
restrictive legends and in such permitted denominations and registered in such
names the Executive may request in connection with the sale of Registrable
Securities pursuant to such shelf registration statement.

              (i) Subject to Paragraph 8 below, upon the occurrence of any event
contemplated by Paragraph 2(c)(v) above, the Company shall promptly prepare a
post-effective amendment to such shelf registration statement or an amendment or
supplement to the related prospectus or file any other required document so
that, as thereafter delivered to purchasers of the Registrable Securities
included therein, the prospectus will not include an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. If the Company notifies the Executive of the occurrence of
any event contemplated by Paragraphs 2(c)(iii), (iv) (limited to the
jurisdiction of such suspension) or (v) above or of a delay pursuant to
Paragraph 8 below, the Executive shall suspend the use of the prospectus and any
proposed sales of securities registered pursuant to such registration statement
until the requisite changes to the prospectus have been made or the Company has
notified the Executive that the reason for such delay no longer exists, as the
case may be and the Executive has received copies of a supplemented or amended
prospectus which is no longer defective.

              (j) The Company shall use its best efforts to comply with all
applicable rules and regulations of the Commission and shall make generally
available to its security holders or otherwise provide in accordance with
Section 11(a) of the Securities Act as soon as practicable after the effective
date of such shelf registration statement an earnings statement satisfying the
provisions of Section 11(a) of the Securities Act.

              (k) The Company may require the Executive to furnish to the
Company such information regarding the Executive and the distribution of such
Registrable Securities as may be required by applicable law or regulation for
inclusion in such shelf registration statement.

              (l) The Company shall, if requested, promptly include or
incorporate in a prospectus supplement or post-effective amendment to such shelf
registration statement, such information as the managing underwriters reasonably
agree should be included therein and to which the Company does not reasonably
object and shall make all required filings of such prospectus supplement or
post-effective amendment as soon as practicable after they are notified of the
matters to be included or incorporated in such prospectus supplement or
post-effective amendment; PROVIDED, HOWEVER, that the Company shall not be
obligated to include in any such prospectus supplement or post-effective
amendment to such shelf registration statement any requested information that is
unreasonable in scope taking into account the Company's most recent prospectus
or prospectus supplement used in connection with a primary or secondary offering
of equity securities by the Company and the Company's periodic reports under the
Exchange Act.

              (m) The Company shall enter into such customary agreements
(including an underwriting agreement in customary form in the event of an
underwritten offering as set forth in Paragraph 7 below) to take all other
appropriate actions in order to expedite or facilitate the registration and the
disposition of the Registrable Securities, and in connection therewith, if an
underwriting agreement is entered into, cause the same to contain
indemnification provisions and procedures


                                      -3-



substantially identical to those set forth in Paragraph 5 below with respect
to the underwriters and controlling persons of the underwriters.

              (n) The Company shall:

              (i) make reasonably available for inspection by the Executive, any
       underwriter participating in any disposition pursuant to such shelf
       registration statement, and any attorney, accountant or other agent
       retained by the Executive or any such underwriter all relevant financial
       and other records, pertinent corporate documents and properties of the
       Company and its subsidiaries;

              (ii) cause the Company's officers, directors and employees to make
       reasonably available for inspection all relevant information reasonably
       requested by the Executive or any such underwriter, attorney, accountant
       or agent in connection with any shelf registration statement, in each
       case, as is customary for similar due diligence examinations; provided,
       however, that any information that is designated in writing by the
       Company, in good faith, as confidential at the time of delivery of such
       information shall be kept confidential by the Executive or any such
       underwriter, attorney, accountant or agent, unless such disclosure is
       made in connection with a court proceeding or required by law, or such
       information becomes available to the public generally or through a third
       party without an accompanying obligation of confidentiality;

              (iii) make such representations and warranties to the Executive
       and the managing underwriters, if any, in form, substance and scope as
       are customarily made by the Company to underwriters in primary
       underwritten offerings and covering matters including, but not limited
       to, those set forth in Paragraph 4 below;

              (iv) obtain opinions of counsel to the Company (which counsel and
       opinions (in form, scope and substance) shall be reasonably satisfactory
       to the managing underwriters, if any) addressed to the Executive and
       underwriters, if any, covering such matters as are customarily covered in
       opinions requested in underwritten offerings; provided, however, that the
       Company shall not be obligated to obtain such opinions in connection with
       any sale (other than in an underwritten offering) of securities by the
       Executive more than twice during any 12 consecutive month period;

              (v) obtain "cold comfort" letters from the independent public
       accountants of the Company addressed to the Executive and the
       underwriters, if any, in customary form and covering matters of the type
       customarily covered in "cold comfort" letters in connection with primary
       underwritten offerings; provided, however, that the Company shall not be
       obligated to obtain such letters in connection with any sale (other than
       in an underwritten offering) of securities by the Executive more than
       twice during any 12 consecutive month period or, if applicable accounting
       procedures and practices do not permit the rendering of such "cold
       comfort" letter in an offering of the type being effected; and

              (vi) deliver such documents and certificates as may be reasonably
       requested by managing underwriters, if any, and in accordance with
       customary conditions contained in the underwriting agreement or other
       agreement entered into by the Company.

              (o) The Company shall use its commercially reasonable best efforts
to take all other steps necessary to effect the registration, offering and sale
of the Registrable Securities covered by such shelf registration statement
contemplated hereby.


                                     -4-



              (p) Executive shall not, during any period in which of any his
Registrable Securities are included in any effective registration statement,
effect any stabilization or other transactions or engage in any stabilization or
other activity in connection with equity securities of the Company in
contravention of Rule 10b-7, Regulation M, or Rule 10b-2 under the Exchange Act.

Executive shall furnish each broker through whom Executive offers Registrable
Securities such number of copies of the prospectus as the broker may require and
otherwise comply with the prospectus delivery requirements under the Securities
Act.

3.   EXPENSES. The Company agrees to pay all Registration Expenses in connection
     with any registration pursuant to Paragraph 1 above.

4.   REPRESENTATIONS. The Company represents and warrants to, and agrees with,
     the Executive that:

              (a) Any registration statement and each prospectus contained
therein filed pursuant to Paragraph 1 above and any further amendments or
supplements to any such registration statement or prospectus, when it becomes
effective or is filed with the Commission and, in the case of an underwritten
offering of Registrable Securities, at the time of the closing under the
underwriting agreement relating thereto, will conform in all material respects
to the requirements of the Securities Act and will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading;
provided, however, that this representation and warranty shall not apply to any
statements or omissions made in reliance upon and in conformity with information
set forth in a questionnaire (or any other written information) furnished to the
Company by the Executive.

              (b) Any documents incorporated by reference in any Prospectus
referred to in Paragraph 3(a) above, when they become or became effective or are
or were filed with the Commission, as the case may be, will conform or conformed
in all material respects to the requirements of the Securities Act or the
Exchange Act, as applicable, and none of such documents will contain or
contained an untrue statement of a material fact or will omit or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading.

              (c) No person has been or shall be granted registration rights
inconsistent with this Agreement; provided, however, that the Company may permit
any registration statement filed pursuant hereto to include securities of
securityholders other than the Executive. Notwithstanding the foregoing, the
Company agrees that no other securityholder of the Company shall be granted any
"piggyback" rights with respect to any underwritten offering of securities being
made by the Executive in accordance with the terms hereof.

5. INDEMNIFICATION

              (a) Upon the registration of the Registrable Securities pursuant
to a registration statement filed as contemplated by Paragraph 1 hereof (a
"Registration Statement"), the Company shall, and it hereby agrees to, indemnify
and hold harmless the Executive against any losses, claims, damages or
liabilities to which the Executive may become subject under the Securities Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions
(pending or threatened) in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
such Registration Statement under which such Registrable Securities were
registered under the Securities Act, or any prospectus contained therein or
furnished by the Company to the Executive, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not


                                     -5-



misleading, and the Company shall, and it hereby agrees to, reimburse the
Executive for any legal or other expenses reasonably incurred by him in
connection with investigating or defending any such action or claim;
provided, however, that the Company shall not be liable to the Executive in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in such Registration Statement
or prospectus, or amendment or supplement, in reliance upon and in conformity
with any written information (including without limitation, any
questionnaire) furnished to the Company by the Executive expressly for use
therein or from the failure of the Executive to comply with the prospectus
delivery requirements or other applicable provisions of the securities laws.

              (b) The Company may require, as a condition to filing any
Registration Statement, that the Company shall have received an undertaking
reasonably satisfactory to it from the Executive to (i) indemnify and hold
harmless the Company, its directors, officers who sign any Registration
Statement, each person, if any, who controls the Company within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act, and
any other holder of Common Stock that are included in such Registration
Statement against any losses, claims, damages or liabilities to which the
Company or such other persons may become subject, under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in such Registration Statement, or
any prospectus contained therein or furnished by the Company to any such holder
or underwriter, or any amendment or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information furnished in writing
to the Company by the Executive expressly for use therein (including, without
limitation, any questionnaire), and (ii) reimburse the Company for any legal or
other expenses reasonably incurred by the Company in connection with
investigating or defending any such action or claim;

              (c) Promptly after receipt by an indemnified party under Paragraph
5(a) or (b) above of written notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against an
indemnifying party pursuant to the indemnification provisions of or contemplated
by this Paragraph 5, notify such indemnifying party in writing of the
commencement of such action; but the omission to so notify the indemnifying
party shall not relieve it from any liability which it may have to any
indemnified party other than under the indemnification provisions of or
contemplated by Paragraph 5(a) or (b) above, and then only to the extent that
the indemnifying party is actually prejudiced thereby. In case any such action
shall be brought against any indemnified party and it shall notify an
indemnifying party of the commencement thereof, such indemnifying party shall be
entitled to participate therein and (unless the indemnified party reasonably
concludes that such representation would involve a conflict of interest), to the
extent that it shall wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and, after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, such indemnifying party shall not be liable to such indemnified
party for any legal expenses of other counsel or any other expenses, in each
case subsequently incurred by such indemnified party, in connection with the
defense thereof other than reasonable costs of investigation. No indemnifying
party shall, without the written consent of the indemnified party, effect the
settlement or compromise of, or consent to the entry of any judgment with
respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from


                                     -6-



all liability arising out of such action or claim and (ii) does not include a
statement as to, or an admission of, fault, culpability or a failure to act,
by or on behalf of any indemnified party. An indemnifying party will not be
liable for any settlement of any action or claim effected without its written
consent (which shall not be unreasonably withheld).

              (d) Each party hereto agrees that, if for any reason the
indemnification provisions contemplated by Paragraph 5(a) or (b) are unavailable
to or insufficient to hold harmless an indemnified party in respect of any
losses, claims, damages or liabilities (or actions in respect thereof) referred
to therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of the indemnifying party and the indemnified
party in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations. The relative fault of such
indemnifying party and indemnified party shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact relates to
information supplied by such indemnifying party or by such indemnified party,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The parties hereto
agree that it would not be just and equitable if contribution pursuant to this
Paragraph 5(d) were determined by pro rata allocation or by any other method of
allocation which does not take account of the equitable considerations referred
to in this Paragraph 5(d). The amount paid or payable by an indemnified party as
a result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above shall be deemed to include any legal or other fees or
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

6. DEFINITIONS.

              (a) "Registrable Securities" shall mean (i) the 500,000 shares of
Common Stock issuable upon exercise of the Additional Company Stock Options to
be granted by the Company to the Executive pursuant to Section 3.2 of the
Agreement and (ii) the 1,250,000 shares of Common Stock issuable under the
Additional Restricted Units to be granted to the Executive pursuant to Section
3.3 of the Agreement, and in each case, any securities issued as a distribution
on or acquired upon exercise of rights distributed with respect to such shares
of Common Stock (collectively with the Common Stock, the "Securities"); provided
that such Securities shall cease to be Registrable Securities when such
Securities (x) have been sold or otherwise transferred by the Executive, whether
pursuant to an effective registration statement or otherwise, or (y) have become
eligible for sale pursuant to Rule 144(k) (or any similar provision then in
force) under the Securities Act.

              (b) "Registration Expenses" means all expenses incident to the
Company's performance of or compliance with its obligations hereunder, including
without limitation, (i) all Commission and any NASD registration and filing fees
and expenses, (ii) all fees and expenses in connection with the qualification of
the Registrable Securities for offering and sale under the State securities and
blue sky laws of such States as may be reasonably requested by the Executive
(provided, however, that nothing herein shall require the Company to qualify as
a foreign corporation in any jurisdiction where it would not otherwise be
required to qualify but for such qualification, to consent to general service of
process or taxation in any such jurisdiction or to make any changes to the
Company's certificate of incorporation or bylaws, (iii) all expenses relating to
the preparation, printing, distribution and reproduction of any registration
statement required to be filed as contemplated herein, each prospectus included
therein or prepared for distribution, each amendment or supplement to the
foregoing,


                                     -7-



the certificates representing the Securities and all other documents relating
there, (iv) messenger and delivery expenses, (v) internal expenses
(including, without limitation, all salaries and expenses of the Company
officers and employees performing legal or accounting duties), (vi) fees,
disbursements and expenses of counsel and independent certified public
accountants of the Company and (vii) reasonable fees, disbursements and
expenses of one counsel for the Executive retained in connection with such
registration and reasonable fees and disbursements of underwriters and
distribution participants customarily paid by the issuer. To the extent that
any Registration Expenses are incurred, assumed or paid by the Executive, the
Company shall reimburse the Executive for the full amount of the Registration
Expenses so incurred, assumed or paid promptly after receipt of a request
therefor. Notwithstanding the foregoing, the Executive shall pay all agency
fees and commissions and underwriting discounts and commissions and the legal
and other fees of underwriters, if any, resulting from any failure by
Executive to consummate an underwritten offering or not covered by clause
(vii), if any, attributable to the sale of such Registrable Securities and
the fees and disbursements of any counsel or other advisors or experts
retained by the Executive or underwriters, other than those specifically
referred to above.

     7.   UNDERWRITTEN OFFERING. The Executive, if he so desires, may sell
          Registrable Securities in an underwritten offering. In any such
          underwritten offering, the investment banker or bankers and manager or
          managers that will administer the offering will be selected by, and
          the underwriting arrangements with respect thereto will be approved by
          the Executive; provided, however, that (i) such investment bankers and
          managers and underwriting arrangements must be reasonably satisfactory
          to the Company, such satisfaction not to be unreasonably withheld,
          (ii) the Company shall not be obligated to arrange for more than one
          underwritten offering during any consecutive twelve-month period or

          agreements restricting his sales of securities of the Company for such
          reasonable periods not to exceed 180 days as the lead underwriters may
          require.

INTEGRA LIFESCIENCES EXTENDS EMPLOYMENT AGREEMENT OF CHIEF EXECUTIVE OFFICER

PLAINSBORO, N.J.--(BUSINESS WIRE)--Dec. 22, 2000--Integra LifeSciences Holdings
Corporation (Nasdaq:IART) today announced that Stuart M. Essig, Integra's
President and Chief Executive Officer, has extended his employment agreement
with the Company through December 31, 2005.

In making the announcement, Dr. Richard Caruso, Integra's Chairman, said, "We
are delighted to have Stuart on board for the next five years. His demonstrated
leadership has strengthened our senior management team. He has proven that his
substantial expertise in negotiating corporate alliances and in public company
mergers and acquisitions can dramatically increase shareholder value. Stuart's
considerable financial and managerial discipline has led us to profitability and
dramatic revenue growth. Integra is a company that has grown through acquisition
of technologies and products as well as through internal development. We expect
Stuart to continue to drive that activity, as well as to continue to build on
Integra's growing recognition with the investment community."

Integra is a NASDAQ-listed company with a market capitalization of approximately
$250 million. Integra is an established manufacturer and marketer of a broad
range of instruments and implantable and single-use specialty medical products,
and a leader in the separate fields of medical devices for the neurosurgical
market and implantable devices for the regeneration of tissue in vivo.

"Mr. Essig has earned our confidence through continued execution on Integra's
programs for the growth and development of the Company," said Neal Moszkowski,
one of Integra's directors and partner of Soros Private Equity Partners LLC. "We
are delighted to have Mr. Essig's continued leadership at the company in the
coming years."

Mr. Essig has extended his employment agreement for an additional four-year
period through December 31, 2005. In connection with the extension of the
agreement with Integra, he received options for 500,000 shares of Integra common
stock granted under two different stock option plans previously approved by the
stockholders. Mr. Essig is also entitled to receive a deferred payment
consisting of 1.25 million Integra shares. Integra expects to take a one-time,
non-cash compensation charge of approximately $13.5 million for this deferred
payment in the fourth quarter of this year.

Prior to joining Integra at the end of 1997, Mr. Essig supervised the medical
technology practice of Goldman Sachs as a managing director. At the time he
joined the Company, he had 10 years of broad health care experience, including
acquisitions, divestitures, strategic alliances, principal investing and capital
markets. While at Goldman Sachs, Mr. Essig, 39, served as a senior merger and
acquisitions advisor to a broad range of domestic and international medical
technology, pharmaceutical and biotechnology clients. His experience also
includes substantial financing and investing experience. He holds an MBA and
Ph.D. in Financial Economics from the University of Chicago and a BA from
Princeton University.

Integra's leading neurosurgical devices include the Camino(R) and Ventrix(R)
lines of intra-cranial pressure monitors and the Selector Integra(R) Ultrasonic
Aspirator. Integra's leading tissue regeneration products include DuraGen(TM)
Dural Graft Matrix (for repair and regeneration of dura mater), INTEGRA(R)
Dermal Regeneration Template (for regeneration of dermis, sold through the
Ethicon division of Johnson & Johnson) and the Biomend(R) Absorbable Collagen
Membrane (for the guided repair of the gingiva). In addition, Integra makes or
sells hundreds of other surgical instruments, shunts for the management of


                                     -1-




hydrocephalus and surgery on the carotid artery, Integra Coblation(R), and
collagen products for general and dental surgery.

In less than three years, Integra has transformed itself from a traditional
biotechnology company focused on product development to a fully-integrated
medical device company. Since the beginning of 1998, Integra has launched many
new products and consummated four significant acquisitions, two major strategic
alliances, and numerous other smaller transactions. The result is that Integra's
quarterly revenues have risen more than five-fold in the last three years.
Integra is now profitable on an operating basis, which distinguishes it from
virtually all other tissue regeneration companies, and many other medical device
companies.

Integra LifeSciences Holdings Corporation has its corporate headquarters in
Plainsboro, NJ. Manufacturing and research facilities are also located in San
Diego, CA, Anasco, Puerto Rico, Andover, England and Exton, PA. The Company has
approximately 510 permanent employees. Please visit the Company's Website at
