ITEM 5.         OTHER EVENTS

         On December 27, 1997, Integra LifeSciences Corporation (the "Company")
entered into an Employment Agreement, a Stock Option Grant and Agreement and a
Restricted Units Agreement with Stuart M. Essig ("Executive").

         Under the Employment Agreement, Executive is to serve as the President
and Chief Executive Officer of the Company and report directly to the Board of
Directors. As compensation for Executive's services during the first year of the
agreement, the Company will pay Executive an annual salary of $300,000. For each
subsequent year of the Employment Agreement, Executive's salary will be $300,000

plus any increases as may be established by the Board. Executive is also
entitled to receive a performance bonus of up to 50% of Executive's base salary,
based upon the satisfaction of certain performance goals pertaining to the
trading price of the Company's common stock. Executive is also entitled 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
the Company by paying premium payments of $5,000 per year for such policy. At
the request of Executive, the Company will disburse a loan in the amount of up
to $500,000 subject to certain conditions. Executive is also entitled to
participate in the Company's medical, disability, pension and other employee
benefit plans and programs maintained from time to time by the Company for the
benefit of its senior executives. The Employment Agreement is for an initial
term through December 31, 2001 and shall automatically extend on December 31,
2001 and on each subsequent one-year anniversary thereof for one year unless the
Company or Executive provides written notice of termination at least six months
prior to such anniversary.

         Under the Stock Option Grant and Agreement, the Company granted
Executive options under the Company's 1996 Incentive Stock Option and
Non-Qualified Stock Option Plan, as amended (the "1996 Option Plan"), to
purchase 1,000,000 shares (the "Option Shares") of the Company's common stock at
an exercise price of $2.9375 per share and with an expiration date of December
26, 2007. The options shall vest and become exercisable with respect to 250,000
shares on December 27, 1998 and shall vest and become exercisable thereafter
with respect to 1/36th of the remaining shares on the first business day of each
following month; provided that the option shall become immediately vested and
exercisable in the event of (a) a change in control of the Company or (b) the
termination of Executive's employment (i) by the Company without cause, (ii) by
Executive for good reason or (iii) due to Executive's death.

         Under the Restricted Units Agreement, the Company granted Executive
2,000,000 restricted units, each unit representing the right to receive one
share of the Company's common stock. The shares of common stock underlying the
restricted units (the "Unit Shares") shall be delivered to Executive on January
1, 2002 if Executive is employed by the Company on December 31, 2001. Executive
has the right to defer delivery of the Unit Shares for a period of up to six
years. The Unit Shares may be delivered to Executive prior to January 1, 2002 in
the



                                       2




event of (a) a change of control of the Company while he is employed by the
Company or (b) a termination of Executive's employment with the Company other
than (i) for cause or (ii) due to his voluntary departure (other than for good
reason or due to disability). If, prior to December 31, 2001, (a) Executive's
employment with the Company is terminated for cause or (b) he voluntarily leaves
his employment with the Company (other than for good reason or due to
disability), the Unit Shares shall be distributed to Executive on January 1,
2018. The Company also agreed to file, following the request of Executive, a

registration statement with the Securities and Exchange Commission to register
the sale by Executive of the Option Shares and the Unit Shares pursuant to the
Securities Act of 1933, as amended. In connection with the Restricted Units
Agreement, the Company will incur a non-cash deferred compensation charge of
$5,875,000 in the fourth quarter of 1997.

         In connection with the authorization by the Board of Directors of the
execution and delivery of the foregoing agreements, the Board of Directors
approved (a) an amendment to the Company's by-laws to provide that (i) the
Company shall have a Chief Executive Officer, who shall have full authority with
respect to the conduct of the business of the Company, subject only to approval
of the Board, and (ii) in the absence of a duly appointed Chief Executive
Officer, such authority shall devolve upon the Company's President, (b) an
amendment to Section 4 of the Company's 1996 Stock Option Plan to increase the
number of options issuable under the Plan to any one individual over any
one-year period from 300,000 to 1,000,000, and (c) an amendment to Section 12(b)
of the Company's 1996 Stock Option Plan to provide that the Plan may be amended
by the Company's shareholders pursuant to written consent in lieu of a meeting.

shall be held at such place, within the State of Delaware or elsewhere; as may
be fixed from time to time by the Board of Directors. If no place is so fixed
for a meeting, it shall be held at the Corporation's then principal executive
office.

                  Section 2.02. Annual Meeting. The annual meeting of
stockholders shall be held, unless the Board of Directors shall fix some other
hour or date therefor, at nine o'clock A.M. on the first Monday of May in each
year, if not a legal holiday under the laws of Delaware, and, if a legal
holiday, then on the next succeeding secular day not a legal holiday under the
laws of Delaware, at which the stockholders shall elect by plurality vote a
Board of Directors, and transact such other business as may properly be brought
before the meeting.

                  Section 2.03. Notice of Annual Meetings. Written notice of the
annual meeting stating the place, date and hour of the meeting shall be given to
each stockholder entitled to vote at such meeting not less than 10 days nor more
than 60 days before the date of the meeting.

                  Section 2.04. List of Stockholders. The officer who has charge
of the stock ledger of the Corporation shall prepare and make, at least 10 days
before every meeting of stockholders, a complete list of stockholders entitled
to vote at the meeting, arranged in alphabetical order, and showing the address
of each 




stockholder and the number of shares registered in the name of each
stockholder. Such list shall be open to the examination of any stockholder, for
any purpose germane to the meeting, during ordinary business hours, for a period
of at least 10 days prior to the meeting, either at a place within the city
where the meeting is to be held, which place shall be so specified in the notice
of the meeting, or, if not so specified, at the place where the meeting is to be
held. The list shall also be produced and kept at the time and place of the
meeting during the whole time thereof, and may be inspected by any stockholder
who is present.

                  Section 2.05. Special Meetings. Special meetings of the
stockholders, for any purpose or purposes, unless otherwise prescribed by
statute or by the Certificate of Incorporation, may be called by the Chairman of
the Board or the President and shall be called by the President or Secretary at
the request in writing of a majority of the Board of Directors. Such request
shall state the purpose or purposes of the proposed meeting. Business transacted

                  Section 2.07. Quorum: Voting. The holders of a majority of the
stock issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall constitute a quorum at all meetings of the
stockholders for the transaction of business except as otherwise provided by
statute or by the Certificate of Incorporation. If, however, such quorum shall
not be present or represented at any meeting of the stockholders, the
stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum shall be present or
represented. At such adjourned meeting at which a quorum shall be present or
represented any business may be transacted which might have been transacted at
the meeting as originally notified. If the adjournment is for more than thirty
days, or if after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder of
record entitled to vote at the meeting. When a quorum is present at any meeting,
except for elections of directors, which shall be decided by plurality vote, the
vote of the holders of a majority of the stock having voting power present in
person or represented by proxy shall decide any question brought before such
meeting, unless the question is one 

                                      -2-



upon which by express provision of statute or of the Certificate of
Incorporation, a different vote is required, in which case such express
provision shall govern and control the decision of such question. Unless
otherwise provided in the Certificate of Incorporation, each stockholder shall
at every meeting of stockholders be entitled to one vote in person or by proxy

for each share of the capital stock having voting power held by such
stockholder, but no shares shall be voted pursuant to a proxy more than three
years after the date of the proxy unless the proxy provides for a longer period.

                  Section 2.08. Action Without a Meeting. Unless otherwise
restricted by the Certificate of Incorporation, any action required or permitted
to be taken at any annual or special meeting of stockholders may be taken
without a meeting, without prior notice and without a vote, if a consent or
consents in writing setting forth the action so taken shall be signed by the
holders of outstanding stock having not less than the minimum number of votes
that would be necessary to authorize or take such action at a meeting at which
all shares entitled to vote thereon were present and voted and shall be
delivered to the corporation by delivery to its registered office in the State,
its principal place of business, or an officer or agent of the corporation
having custody of the book in which proceedings of meetings of stockholders are
recorded. Delivery made to a corporation's registered office shall be by hand or
by certified or registered mail, return receipt requested. Every written consent
shall bear the date of signature of each stockholder who signs the consent and
no written consent shall be effective to take the corporate action referred to
therein unless, within sixty days after the earliest dated consent delivered in
the manner required by this Section to the corporation, written consents signed
by a sufficient number of stockholders to take action are delivered in the
manner required by this Section to the Corporation. Prompt notice of the taking
of the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing.

                                    ARTICLE 3
                                    DIRECTORS

directors of the Corporation shall be not less than three nor more than

Directors. The directors shall be elected at the annual meeting of the

Directors need not be stockholders.

                                      -3-



                  Section 3.02. Vacancies. Vacancies and newly created
directorships resulting from any increase in the authorized number of directors
may be filled by a majority of the directors then in office, though less than a
quorum, or by a sole remaining director, and the directors so chosen shall hold
office until the next annual election and until their successors are duly
elected and shall qualify, unless sooner displaced. If there are no directors in
office, then an election of directors may be held in the manner provided by
statute. If, at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a majority
of the whole board (as constituted immediately prior to any such increase), the
Court of Chancery may, upon application of any stockholder or stockholders
holding at least 10 percent of the total number of the shares at the time

outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office.

                  Section 3.03. Resignations. Any director may resign at any
time by giving written notice to the Board of Directors, the Chairman of the
Board, the President, or the Secretary. Such resignation shall take effect at

otherwise specified therein, the acceptance of such resignation shall not be
necessary to make it effective.

                  Section 3.04. Direction of Management. The business of the
Corporation shall be managed under the direction of its Board of Directors,
which may exercise all such powers of the Corporation and do all such lawful
acts and things as are not by statute or by the Certificate of Incorporation or
by these By-Laws directed or required to be exercised or done by the
stockholders.

                  Section 3.05. Place of Meetings. The Board of Directors of the
Corporation may hold meetings, both regular and special, either within or
without the State of Delaware.

                  Section 3.06. Annual Meeting. Immediately after each annual
election of directors, the Board of Directors shall meet for the purpose of
organization, election of officers, and the transaction of other business, at
the place where such election of directors was held or, if notice of such
meeting is given, at the place specified in such notice. Notice of such meeting
need not be given. In the absence of a quorum at said meeting, the same may be
held at any other time and place which shall be specified in a notice given as
hereinafter provided for special meetings of the Board of Directors, or as shall
be specified in a written waiver signed by the directors, if any, not attending
and participating in the meeting.

                                      -4-



                  Section 3.07. Regular Meetings. Regular meetings of the Board
of Directors may be held without notice at such time and place as shall from
time to time be determined by the Board.

                  Section 3.08. Special Meetings. Special meetings of the Board
of Directors may be called by the Chairman of the Board, or the President on 2
days' notice to each director; either personally (including telephone), or in
the manner specified in Section 4.01; special meetings shall be called by the
Chairman of the Board, or the President or the Secretary in like manner and on
like notice on the written request of two directors.

                  Section 3.09. Quorum: Voting. At all meetings of the Board, a
majority of the directors shall constitute a quorum for the transaction of
business; and at all meetings of any committee of the Board, a majority of the
members of such committee shall constitute a quorum for the transaction of
business. The act of a majority of the directors present at any meeting of the
Board of Directors or any committee thereof at which there is a quorum present

shall be the act of the Board of Directors or such committee, as the case may
be, except as may be otherwise specifically provided by statute or by the
Certificate of Incorporation. If a quorum shall not be present at any meeting of
the Board of Directors or committee thereof, the directors present thereat may
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present.

                  Section 3.10. Action Without a Meeting. Any action required or
permitted to be taken at any meeting of the Board of Directors or of any
committee thereof may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the Board or committee.

                  Section 3.11. Participation in Meetings. One or more directors
may participate in any meeting of the Board or committee thereof by means of
conference telephone or similar communications equipment by which all persons
participating can hear each other.

                  Section 3.12. Committees of Directors. The Board of Directors
may, by resolution passed by a majority of the whole Board, designate one or
more committees, each committee to consist of one or more of the directors of
the Corporation. The Board may designate one or more directors as alternate
members of any committee, who may replace any absent or disqualified member at
any meeting of the committee. Any such committee, to the extent provided in the
resolution, shall have and may exercise all of the powers and authority of the
Board of Directors and may 


                                      -5-



authorize the seal of the Corporation to be affixed to all papers which may
require it, but no such committee shall have the power or authority in reference
to amending the Certificate of Incorporation (except that a committee may, to
the extent authorized in the resolution providing for the issuance of shares of
stock adopted by the Board of Directors, fix any preferences or rights of such
shares relating to dividends, redemption, dissolution, any distribution of
assets of the Corporation or the conversion into, or the exchange of such shares
for, shares of any other class or classes or any other series of the same or any
other class or classes of stock of the Corporation), adopting an agreement of
merger or consolidation, recommending to the stockholders the sale, lease or
exchange of all or substantially all of the Corporation's property and assets,
recommending to the stockholders a dissolution of the Corporation or a
revocation of a dissolution, or amending the By-Laws of the Corporation; and,
unless the resolution expressly so provides, no such committee shall have the
power or authority to declare a dividend, to authorize the issuance of stock, or
to adopt a certificate of ownership and merger. Such committee or committees
shall have such name or names as may be determined from time to time by
resolution adopted by the Board of Directors. Each committee shall keep regular
minutes of its meetings and report the same to the Board of Directors when
requested.

                  Section 3.13. Compensation of Directors. Each director shall

be entitled to receive such compensation, if any, as may from time to time be
fixed by the Board of Directors. Members of special or standing committees may
be allowed like compensation for attending committee meetings. Directors may
also be reimbursed by the Corporation for all reasonable expenses incurred in
traveling to and from the place of each meeting of the Board or of any such
committee or otherwise incurred in the performance of their duties as directors.

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 acknowledges that Executive

until December 26, 2007 and shall be granted on the other terms and conditions
set forth in the Stock Option Grant and Agreement attached as Exhibit A hereto.

giving notice no less than six months 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 Unit Shares shall be

delivered to Executive as provided in Section 4 below unless the Unit Shares

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 substantially equivalent to the Company's
then-current Health Benefits. Upon Executive's death, Executive's Company Stock
Option shall immediately vest and shall be exercisable until the later of (a)
one year following his death or (b) December 31, 2001, but in no event beyond
December 26, 2007. As promptly as practicable following Executive's death, but
in no event later than 90 days following such death, the 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, 2001, and (c) Health Benefits (subject
to continued contributions required by Executive for such benefits) to the
extent permitted by the


                                      -7-



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; 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,
2001, 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, the vested portion of Executive's Company Stock Option

shall be exercisable until the later of (a) one year following the date of
termination and (b) December 31, 2001, but in no event later than December 26,
2007, and the 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. Upon termination for Cause in accordance with this Section 4.3 prior
to December 31, 2001, the vested portion of Executive's Company Stock Option
shall be exercisable until December 26, 2007 and the 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


                                      -8-



                  (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, 2001, 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. In such circumstance, the vested portion of Executive's
Company Stock Option on the date of Executive's departure shall be exercisable
until December 26, 2007, the non-vested portion of Executive's Company Stock
Option shall terminate on the date of Executive's departure and the Unit Shares
shall be distributed to Executive on January 1, 2018.




                                      -9-



           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 the Company shall pay to Executive a lump sum cash payment
equal to the sum of (A) the Accrued Obligations and (B) his Base Salary
(including the minimum increases provided therein) during the remainder of the
then-current Term, the Company Stock Option granted to Executive shall become
immediately vested on the date of such termination and exercisable through
December 26, 2007, and the 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 3.6(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;


                                      -10-



                  (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;

                  (v) the Company's failure to provide the Company Stock Option
or the Restricted Units or the Company's material breach of the Company Stock
Option Plan, the Company Stock Option Agreement or the 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 approved 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 Statement subject to the terms of Exhibit B hereto.

Executive's right to terminate his employment hereunder for Good Reason shall
not be affected by his Disability. Subject to 


                                      -11-



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; and

              (b) Amounts owed to Executive under this Agreement or the
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 3.8 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 Company's obligation
to make the payments provided for in this Agreement, the Stock Option Agreement,
the Registration Rights Agreement, and the 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.

SECTION 5.    ACCELERATION OF OPTION VESTING AND DELIVERY OF UNIT SHARES



                                      -12-



          5.1 Triggering Events. Except as otherwise provided in Section 4.3
hereof, if (a) a Change in Control (as defined in Section 6.1 below) occurs or
(b) Caruso or trusts or other entities for the benefit of Caruso or his
immediate family members dispose of in the aggregate 7.5 million shares of the
Common Stock (or its equivalent) now owned by such persons or trusts or other
entities (each a "Triggering Event"), then the Company Stock Option shall vest
and be exercisable through December 26, 2007 and the Unit Shares shall be
distributed to Executive immediately prior to such transaction.

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 


                                      -13-



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 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; 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 


                                      -14-




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


                                      -15-



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 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.






                                      -16-



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.



                                      -17-



          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 any other 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 


                                      -18-



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 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 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 


                                      -19-



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 Company Stock Option Agreement, the shelf-registration
described in Section 3.2, and the 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 has not
breached, and the performance of his duties hereunder will not breach, any
obligation owed by him to, or any agreement with, any prior employer or 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.





                                      -20-



          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.

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.

              (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. 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. 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 


                                      -22-



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 and provide the benefits hereunder and to enter into the
agreements described in Sections 3.2 and 3.3, 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.

          8.14 Below Market Issuances. The Company hereby agrees that, without
the written consent of Executive, so long as Executive holds Restricted Units or
Company Stock Options and so long as Caruso and trusts or other entities for the
benefit of Caruso or his immediate family hold in the aggregate more than 45% of
the Common Stock, neither the Company nor any subsidiary of the Company shall,
directly or indirectly, issue or sell Common Stock (or any security, warrant or
option convertible into or exercisable for Common Stock) at a price below fair
market value, directly or indirectly, to (a) any entities or individuals (or
immediate family members of any such individuals) which, directly or indirectly,
own 45% or more of the Common Stock (an "Affiliate") or any entity, directly or
indirectly, controlled by an Affiliate or any trusts or other entities
established for the direct or indirect benefit of an Affiliate or (b) any
entities under 45% or more common control with the Company.



                                      -23-



          8.15 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.

          8.16 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.

                                                                       ---------


                     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 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 Exchange Act (as
       defined below).

            (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 and
       the Securities Exchange Act of 1934, as amended (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)   (1) 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;

                 (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. 


                                      -2-



             (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 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
       Paragraph 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.



                                      -3-



             (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
       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


                                      -4-


             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;

                 (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.

             (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.


                                      -5-



                 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 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


                                      -7-



       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 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 


                                      -8-



       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 1,000,000 shares of
       common stock, par value $0.01 per share, of the Company and any
       securities into which such shares are exchanged or reclassified ("Common
       Stock") issuable upon exercise of the Company Options to be granted by
       the Company to the Executive pursuant to Section 3.2 of the Agreement and
       (ii) the 2,000,000 shares of Common Stock issuable upon payment of the
       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 (i) have been sold or
       otherwise transferred by the Executive, whether pursuant to an effective
       registration statement or otherwise or (ii) 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, (a) all Commission and any NASD
       registration and filing fees and expenses, (b) 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, (c) 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, the
       certificates representing the Securities and all other documents relating
       there, (d) messenger and delivery expenses, (e) internal expenses
       (including, without limitation, all salaries and expenses of the Company
       officers and employees performing legal or accounting duties), (f) fees,
       disbursements and expenses of counsel and independent certified public
       accountants of the Company and (g) 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 



                                      -9-



       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 (g), 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 more than a total
       of 5 underwritten offerings and (iii) each underwritten offering shall
       include at least the lesser of (x) $5 million in value of Registrable
       Securities, or (y) 1,500,000 shares of Common Stock (or the equivalent
       thereof), or (z) the balance of the Executive's Registrable Securities,
       are included in such underwritten offering. In connection with any such
       underwritten offering of securities, the Company will agree, to customary
       restrictions on the ability of the Company to sell securities
       substantially similar to the Registrable Securities for a period not to
       exceed 90 days from the date of the related prospectus supplement.

8.     Suspension. Notwithstanding anything contained herein, upon receipt of a
       Request for Sale or for registration from the Executive or a managing
       underwriter, the Company may delay the filing of any such registration
       statement or amendment or supplement if the Company in good faith has a
       valid business reason for such delay, including without limitation, (i)
       that the filing of such amendment or supplement would require the Company
       to include therein material information that has not theretofore been
       made public and which the Company is not then prepared to disclose or
       (ii) that the offering and sale of Registrable Securities by the
       Executive at such time will adversely affect any offering by the Company
       as the case may be, of its securities or any material acquisition or
       financing transaction then contemplated or pending. In connection with
       any public offering of its securities by the Company, Executive shall
       enter into such "Lock up" or other agreements restricting his sales of
       securities of the Company for such reasonable periods not to exceed 180
       days as the lead underwriters may require.

                        STOCK OPTION GRANT AND AGREEMENT
                                   Pursuant to
         1996 INCENTIVE STOCK OPTION AND NON-QUALIFIED STOCK OPTION PLAN
         ---------------------------------------------------------------


         STOCK OPTION GRANT AND AGREEMENT made as of the 27th day of December,
1997 (the "Grant Date"), between INTEGRA LIFESCIENCES 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 Restated and Amended Integra
LifeSciences Corporation 1996 Incentive Stock Option and Non-Qualified Stock

         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 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 1,000,000 shares of Common Stock.

         2. Purchase Price. The purchase price per share of the shares of Common
Stock covered by the Option shall be $2.9375. It is the determination of the
Company's Stock Option Committee (the "Committee") that on the Grant Date the
Option price 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 26, 2007 (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
            250,000 shares on 





            the first 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) immediately prior to the occurrence
            of a "Triggering Event" (as defined in the employment agreement by
            and between the Employee and the Company, dated December 27, 1997
            (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 105 Morgan Lane, 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 



                                       2



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
Optionee, the Company shall provide the Optionee 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 Optionee, the Company shall
use its commercially reasonable best efforts to resolve such problem.

         7. Non-Transferability of Option. This Option is not assignable or
transferrable, 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. If the Employee is terminated for
"Cause", as defined in Section 4.3 of the Employment Agreement, or if the
Executive 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, 2001, 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, 2001. If the Employee's
employment terminates for any reason following December 31, 2001 (including if
the 


                                       3



Employment Agreement is not renewed following December 31, 2001), 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, 2001,
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 of this Option as set forth in Paragraph 3, or if the Employee
dies during any period following termination of employment but while this Option
is still exercisable, then this Option will immediately vest and become
exercisable, and may be exercised 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, 2001 or (ii) one (1) year after the Employee's
death, but in no event beyond the Expiration Date.

         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
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


                                       4



Company is the continuing entity), the Option shall be adjusted so that the
Optionee shall be entitled to receive upon exercise of the Option the same kind
and number of shares or other securities or property which the Optionee 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 Optionee)
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 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.



                                       5



             (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 Optionee 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 Optionee
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.



                                       6



             (i) In the event the parties hereto cannot agree upon an
appropriate and equitable adjustment to the Option, the services of an
independent investment banker mutually acceptable to Optionee 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 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 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 Grant and Option 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 Grant and Option Agreement,
all of the provisions of the Plan as in effect on the Grant Date are hereby
incorporated herein as provisions of this Stock Grant and Option Agreement.


         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

                           RESTRICTED UNITS AGREEMENT

            AGREEMENT, dated as of December 27, 1997, by and between Integra
LifeSciences Corporation, a Delaware corporation (the "Company") and Stuart M.
Essig ("Executive").

            WHEREAS, the Company and Executive have entered into an agreement
(the "Employment Agreement"), dated as of December 27, 1997, pursuant to which
Executive will 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 2,000,000 restricted units (the "Units")
representing an equal number of shares of common stock of the Company, par value
$.01 per share ("Common Stock"), on the terms set forth herein.

            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 27, 1997, deferred compensation in the form of
2,000,000 (two million) 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 shall be paid out to Executive on January 1, 2002, if Executive is still
employed by the Company on December 31, 2001. In the event Executive's
employment with the Company terminates prior to December 31, 2001 or a
Triggering Event occurs, the timing of the payment of the Common Stock
underlying the Units shall be governed by the terms of the Employment Agreement.

            (b) Any shares of Common Stock delivered shall be deposited in an
account designated by Executive and maintained at a brokerage house selected by
Executive. Any such shares of Common Stock 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.

            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 shares of
Common Stock described in Section 12 of this Agreement 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 Committee 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 Common
Stock 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 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 


                                      -2-




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 


                                      -3-



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.

            (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 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, bases 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 


                                      -5-



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.

            12. Notices. Any notice to be given hereunder shall be in writing
and shall be deemed given when delivered personally, sent by courier or telecopy

                                                              December 27, 1997)

                        INTEGRA LIFESCIENCES CORPORATION

                         1996 INCENTIVE STOCK OPTION AND
                         NON-QUALIFIED STOCK OPTION PLAN
                         -------------------------------


                                    SECTION 1

                                     Purpose
                                     -------

          This INTEGRA LIFESCIENCES CORPORATION 1996 INCENTIVE STOCK OPTION AND
NON-QUALIFIED STOCK OPTION PLAN ("Plan") is intended to provide a means whereby
Integra LifeSciences Corporation ("Company") may, through the grant of incentive
stock options and non-qualified stock options (collectively, "Options") to
purchase common stock of the Company ("Common Stock") to Key Employees and
Associates (both as defined in Section 3 hereof), attract and retain such Key
Employees and Associates and motivate them to exercise their best efforts on
behalf of the Company and of any Related Corporation (as defined below).

          For purposes of the Plan, a "Related Corporation" shall mean either a
corporate subsidiary of the Company, as defined in section 424(f) of the
Internal Revenue Code of 1986, as amended ("Code"), or the corporate parent of
the Company, as defined in section 424(e) of the Code. Further, as used in the
Plan (a) the term "ISO" shall mean an Option which, at the time such Option is
granted under the Plan, qualifies as an incentive stock option within the
meaning of section 422 of the Code; and (b) the term "NQSO" shall mean an Option
which, at the time such Option is granted, does not qualify as an incentive
stock option.





                                    SECTION 2

                                 Administration
                                 --------------

          The Plan shall be administered by the Company's Stock Option Committee
("Committee"), which shall consist of at least two and no more than three
directors of the Company who shall be appointed by, and shall serve at the
pleasure of, the Company's Board of Directors ("Board"). Each member of such
Committee, while serving as such, shall be deemed to be acting in his capacity
as a director of the Company. Except as otherwise permitted under section 16(b)
of the Securities Exchange Act of 1934, and the rules and regulations
thereunder, no member of the Committee shall have been granted or awarded
Options pursuant to the Plan or equity securities (within the meaning of 17
C.F.R. ss. 240.16a-1(d)) pursuant to any other plan of the Company or of any of
its affiliates, as defined in the Securities Exchange Act of 1934, at any time
during the period commencing with the date which is one year prior to the date
his service on the Committee began and ending on the date which is one day after
the date on which his service on the Committee ceased. Each member of the
Committee shall also be an "outside director" within the meaning of Treas. Reg.
ss.1.162-27(e)(3), or any successor thereto.

                  The Committee shall have full authority, subject to the terms
of the Plan, to select the Key Employees and Associates (both as defined in
Section 3 hereof) to be granted ISOs and/or NQSOs under the Plan, to grant
Options on behalf of the Company, 

                                      -2-



and to set the date of grant and the other terms of such Options. The Committee
may correct any defect, supply any omission and reconcile any inconsistency in
this Plan and in any Option granted hereunder in the manner and to the extent it
shall deem desirable. The Committee also shall have the authority to establish
such rules and regulations, not inconsistent with the provisions of the Plan,
for the proper administration of the Plan, and to amend, modify or rescind any
such rules and regulations, and to make such determinations and interpretations
under, or in connection with, the Plan, as it deems necessary or advisable. All
such rules, regulations, determinations and interpretations shall be binding and
conclusive upon the Company, its stockholders and all officers and employees and
former officers and employees, and upon their respective legal representatives,
beneficiaries, successors and assigns, and upon all other persons claiming under
or through any of them. No member of the Board or the Committee shall be liable
for any action or determination made in good faith with respect to the Plan or
any Option granted under it.

                                      -3-



                                    SECTION 3


                                   Eligibility
                                   -----------

          (a) In General. Key Employees and Associates shall be eligible to
receive Options under the Plan. Key Employees and Associates who have been
granted an Option under the Plan shall be referred to as "Optionees." More than
one Option may be granted to an Optionee under the Plan.

          (b) Key Employees. "Key Employees" are officers, executives, and
managerial employees of the Company and/or a Related Corporation. Key Employees
shall be eligible to receive ISOs and/or NQSOs.

          (c) Associates. "Associates" are designated non-employee directors,
consultants and other persons providing services to the Company and/or Related
Corporation. Associates shall be eligible to receive only NQSOs.

                                      -4-



                                    SECTION 4

                                      Stock
                                      -----

          Options may be granted under the Plan to purchase up to a maximum of
1,500,000 shares of the Company's Common Stock, par value $0.01 per share;
provided, however, that no Key Employee shall receive Options for more than
1,000,000 shares of Common Stock over any one-year period. However, both limits
in the preceding sentence shall be subject to adjustment as hereinafter
provided. Shares issuable under the Plan may be authorized but unissued shares
or reacquired shares, and the Company may purchase shares required for this
purpose, from time to time, if it deems such purchase to be advisable. 

          If any Option granted under the Plan expires or otherwise terminates
for any reason whatsoever (including, without limitation, the Optionee's
surrender thereof) without having been exercised, the shares subject to the
unexercised portion of such Option shall continue to be available for the
granting of Options under the Plan as fully as if such shares had never been
subject to an Option; provided, however, that (a) if an Option is cancelled, the
shares of Common Stock covered by the cancelled option shall be counted against
the maximum number of shares specified above for which Options may be granted to
a single Key Employee, and (b) if the exercise price of an Option is reduced
after the date of grant, the transaction shall be treated as a cancellation of
the original Option and the grant of a new Option for purposes of counting the
maximum number of shares for which

                                      -5-


Options may be granted to a Key Employee.

                                    SECTION 5


                               Granting of Options
                               -------------------

          From time to time until the expiration or earlier suspension or
discontinuance of the Plan, the Committee may, on behalf of the Company, grant
to Key Employees and Associates under the Plan such Options as it determines are
warranted, subject to the limitations of the Plan; provided, however, that
grants of ISOs and NQSOs shall be separate and not in tandem. The granting of an
Option under the Plan shall not be deemed either to entitle the Key Employee or
Associate to, or to disqualify the Key Employee or Associate from, any
participation in any other grant of Options under the Plan. In making any
determination as to whether a Key Employee or Associate shall be granted an
Option, the type of Option to be granted, and the number of shares to be covered
by such Option, the Committee shall take into account the duties of the Key
Employee or Associate, his or her present and potential contributions to the
success of the Company or a Related Corporation, the tax implications to the
Company and the Key Employee or Associate of any Option granted, and such other
factors as the Committee shall deem relevant in accomplishing the purposes of
the Plan. Moreover, the Committee may provide in the Option that said Option may
be exercised only if certain conditions, as determined by the Committee, are
fulfilled.

                                      -6-


                                    SECTION 6

                                  Annual Limit
                                  ------------

          (a) ISOs. The aggregate Fair Market Value (determined as of the date
the ISO is granted) of the Common Stock with respect to which ISOs are
exercisable for the first time by a Key Employee during any calendar year
(counting ISOs under this Plan and incentive stock options under any other stock
option plan of the Company or a Related Corporation) shall not exceed $100,000.
The term "Fair Market Value" shall mean the value of the shares of Common Stock
arrived at by a good faith determination of the Committee and shall be:

               (1) The mean between the highest and lowest quoted selling price,
if there is a market for the Common Stock on a registered securities exchange or
in an over-the-counter market, on the date specified;

               (2) The weighted average of the means between the highest and
lowest sales on the nearest date before and the nearest date after the specified
date, if there are no such sales on the specified date but there are such sales
on dates within a reasonable period both before and after the specified date;

               (3)  The mean between the bid and asked prices, as reported by
the National Quotation Bureau on the specified date, if actual sales are not
available during a reasonable period beginning before and ending after the
specified date; or

               (4)  If (1) through (3) above are not applicable,


                                      -7-


such other method of determining Fair Market Value as shall be authorized by the
Code, or the rules or regulations thereunder, and adopted by the Committee.

                         Where the Fair Market Value of shares of Common Stock
is determined under (2) above, the average of the means between the highest and
lowest sales on the nearest date before and the nearest date after the specified
date shall be weighted inversely by the respective numbers of trading days
between the dates of reported sales and the specified date (i.e., the valuation
date), in accordance with Treas. Reg. ss. 20.2031-2(b)(1), or any successor
thereto.

          (b) Options Over Annual Limit. If an Option intended as an ISO is
granted to a Key Employee and such Option may not be treated in whole or in part
as an ISO pursuant to the limitation in Subsection (a) above, such Option shall
be treated as an ISO to the extent it may be so treated under such limitation
and as an NQSO as to the remainder. For purposes of determining whether an ISO
would cause such limitation to be exceeded, ISOs shall be taken into account in
the order granted.

          (c) NQSOs. The annual limits set forth above for ISOs shall not apply
to NQSOs.

                                      -8-


                                    SECTION 7

                      Option Agreements - Other Provisions
                      ------------------------------------

          Options granted under the Plan shall be evidenced by written documents
("Option Agreements") in such form as the Committee shall, from time to time,
approve. An Option Agreement shall specify whether the Option is an ISO or NQSO;
provided, however, if the Option is not designated in the Option Agreement as an
ISO or NQSO, the Option shall constitute an ISO if it complies with the terms of
section 422 of the Code, and otherwise, it shall constitute an NQSO. Each
Optionee shall enter into, and be bound by, such Option Agreements, as soon as
practicable after the grant of an Option.

          In connection with the grant of any Option, the associated Option
Agreement may, in the discretion of the Committee, modify or vary any of the
terms of this Plan, including, without limitation, the terms relating to the
vesting and exercise of options, both in general and upon termination of
employment or service, disability, and death, the terms relating to the number
of shares issuable upon the exercise of outstanding Options and the treatment of
Options upon the occurrence of certain corporate transactions; provided,
however, that any further increase in the maximum number of shares which may be
granted to an individual in a single grant pursuant to the Plan shall require
such shareholder approval as may be then required under the applicable rules and
regulations under the Internal Revenue Code of 1986, as amended, or any
successor thereto; and


                                      -9-


that with respect to any grant of an option which is intended to be an incentive
stock option the terms of the Plan, as in effect on the date hereof or
subsequently amended, and not the terms of the applicable Option Agreement,
shall control. In all other cases, in the event of any inconsistency or conflict
between an Option Agreement approved by the Committee and this Plan, the terms
of the Option Agreement shall control to the extent provided in the Option
Agreement. No Option Agreement may be amended except in a writing executed by a
duly authorized officer of the Company and the Optionee or his permitted
successors and assigns.

                                    SECTION 8

                         Terms and Conditions of Options
                         -------------------------------

          Options granted pursuant to the Plan shall include expressly or by
reference the following terms and conditions, as well as such other provisions
not inconsistent with the provisions of this Plan and, for ISOs granted under
this Plan, the provisions of section 422(b) of the Code, as the Committee shall
deem desirable:

          (a) Number of Shares. A statement of the number of shares to which the
Option pertains.

          (b) Price. A statement of the Option price which shall be determined
and fixed by the Committee in its discretion, but shall not be less than the
higher of 100% (110% in the case of ISOs granted to more than 10% shareholders
as discussed in 

                                      -10-


Subsection (j) below) of the fair market value of the optioned shares of Common
Stock, or the par value thereof, on the date the Option is granted.

          (c) Term.

               (1)  ISOs. Subject to earlier termination as provided in
Subsections (e), (f) and (g) below and in Section 9 hereof, the term of each ISO
shall be not more than ten years (five years in the case of more than 10%
shareholders as discussed in Subsection (j) below) from the date of grant.

               (2) NQSOs. Subject to earlier termination as provided in
Subsections (e), (f) and (g) below and in Section 9 hereof, the term of each
NQSO shall be not more than ten years from the date of grant.

          (d) Exercise.

               (1)  General. Options shall be exercisable in such installments
and on such dates, not less than six months from the date of grant, as the

Committee may specify, provided that:

                    (A)  in the case of new Options granted to an Optionee in
replacement for options (whether granted under the Plan or otherwise) held by
the Optionee, the new Options may be made exercisable, if so determined by the
Committee, in its discretion, at the earliest date the replaced options were
exercisable, but not earlier than three months from the date of grant of the new
Options; and

                    (B)  the Committee may accelerate the

                                      -11-


exercise date of any outstanding Options (including, without limitation, the
three-month exercise date referred to in (i) above), in its discretion, if it
deems such acceleration to be desirable.

          Any Option shares, the right to the purchase of which has accrued, may
be purchased at any time up to the expiration or termination of the Option.
Exercisable Options may be exercised, in whole or in part, from time to time by
giving written notice of exercise to the Company at its principal office,
specifying the number of shares to be purchased and accompanied by payment in
full of the aggregate Option exercise price for such shares. Only full shares
shall be issued under the Plan, and any fractional share which might otherwise
be issuable upon exercise of an Option granted hereunder shall be forfeited.

          (2) Manner of Payment. The Option price shall be payable:

                    (A)  in cash or its equivalent;

                    (B)  in the case of an ISO, if the Committee in its
discretion causes the Option Agreement so to provide, and in the case of an
NQSO, if the Committee in its discretion so determines at or prior to the time
of exercise:

                       (i)  in Common Stock previously acquired by the Optionee;
provided that if such shares of Common Stock were acquired through the exercise
of an incentive stock option and are used to pay the Option price of an ISO,
such shares have been held by the Optionee for a period of not less than the
holding



                                      -12-


period described in section 422(a)(1) of the Code on the date of exercise, or if
such shares of Common Stock were acquired through exercise of a non-qualified
stock option or through exercise of an incentive stock option and are used to
pay the Option price of an NQSO, such shares have been held by the Optionee for
a period of more than 12 months on the date of exercise;

                       (ii) in Common Stock newly acquired by the Optionee upon

exercise of such Option (which shall constitute a disqualifying disposition in
the case of an ISO);

                       (iii) in the discretion of the Committee, in any 
combination of (A), (B)(i) and (B)(ii) above; or

                       (iv) by delivering a properly executed notice of exercise
of the Option to the Company and a broker, with irrevocable instructions to the
broker promptly to deliver to the Company the amount of sale or loan proceeds
necessary to pay the exercise price of the Option.

          In the event the Option price is paid, in whole or in part, with
shares of Common Stock, the portion of the Option price so paid shall be equal
to the Fair Market Value on the date of exercise of the Option of the Common
Stock surrendered in payment of such Option price.

                                      -13-


          (e) Termination of Employment or Service. If an Optionee's employment
by or service with the Company (and Related Corporations) is terminated by
either party prior to the expiration date fixed for his or her Option for any
reason other than death or disability, such Option may be exercised, to the
extent of the number of shares with respect to which the Optionee could have
exercised it on the date of such termination, or to any greater extent permitted
by the Committee, by the Optionee at any time prior to the earlier of (i) the
expiration date specified in such Option, or (ii) an accelerated termination
date determined by the Committee, in its discretion, except that, subject to
Section 9 hereof, such accelerated termination date shall not be earlier than
the date of the Optionee's termination of employment or service, and in the case
of an ISO, such termination date shall not be later than three months after the
date of the Key Employee's termination of employment.

                                      -14-


          (f) Exercise upon Disability of Optionee. If an Optionee shall become
disabled (within the meaning of section 22(e)(3) of the Code) during his or her
employment by or service with the Company (and Related Corporations) and, prior
to the expiration date fixed for his or her Option, his or her employment or
service is terminated as a consequence of such disability, such Option may be
exercised, to the extent of the number of shares with respect to which the
Optionee could have exercised it on the date of such termination, or to any
greater extent permitted by the Committee, by the Optionee at any time prior to
the earlier of (i) the expiration date specified in such Option, or (ii) an
accelerated termination date determined by the Committee, in its discretion,
except that, subject to Section 9 hereof, such accelerated termination date
shall not be earlier than the date of the Optionee's termination of employment
or service by reason of disability, and in the case of an ISO, such date shall
not be later than one year after the date of the Key Employee's termination of
employment. In the event of the Optionee's legal disability, such Option may be
so exercised by the Optionee's legal representative.

                                      -15-



          (g) Exercise upon Death of Optionee. If an Optionee shall die during
his or her employment by or service with the Company (and Related Corporations),
and prior to the expiration date fixed for his or her Option, or if an Optionee
whose employment or service is terminated for any reason, shall die following
his or her termination of employment or service but prior to the earliest of (i)
the expiration date fixed for his or her Option, (ii) the expiration of the
period determined under Subsections (e) and (f) above, or (iii) in the case of
an ISO, three months following termination of the Key Employee's employment,
such Option may be exercised, to the extent of the number of shares with respect
to which the Optionee could have exercised it on the date of his or her death,
or to any greater extent permitted by the Committee, by the Optionee's estate,
personal representative or beneficiary who acquired the right to exercise such
Option by bequest or inheritance or by reason of the death of the Optionee, at
any time prior to the earlier of (i) the expiration date specified in such
Option or (ii) an accelerated termination date determined by the Committee, in
its discretion except that, subject to Section 9 hereof, such accelerated
termination date shall not be earlier than one year, nor later than three years
after the date of death.

                                      -16-


          (h) Non-Transferability. No Option shall be assignable or transferable
by the Optionee otherwise than by will or by the laws of descent and
distribution, and during the lifetime of the Optionee, the Option shall be
exercisable only by him or her or by his or her guardian or legal
representative. If the Optionee is married at the time of exercise and if the
Optionee so requests at the time of exercise, the certificate or certificates
shall be registered in the name of the Optionee and the Optionee's spouse,
jointly, with right of survivorship.

                                      -17-


          (i) Rights as a Stockholder. An Optionee shall have no rights as a
stockholder with respect to any shares covered by his or her Option until the
issuance of a stock certificate to him for such shares.

          (j) Ten Percent Shareholder. If the Optionee owns more than 10% of the
total combined voting power of all shares of stock of the Company or of a
Related Corporation at the time an ISO is granted to him or her, the Option
price for the ISO shall be not less than 110% of the fair market value of the
optioned shares of Common Stock on the date the ISO is granted, and such ISO, by
its terms, shall not be exercisable after the expiration of five years from the
date the ISO is granted. The conditions set forth in this Subsection (j) shall
not apply to NQSOs.

                                      -18-


          (k) Listing and Registration of Shares. Each Option shall be subject
to the requirement that, if at any time the Committee shall determine, in its

discretion, that the listing, registration or qualification of the shares
covered thereby upon any securities exchange or under any state or federal law,
or the consent or approval of any governmental regulatory body, is necessary or
desirable as a condition of, or in connection with, the granting of such Option
or the purchase of shares thereunder, or that action by the Company or by the
Optionee should be taken in order to obtain an exemption from any such
requirement, no such Option may be exercised, in whole or in part, unless and
until such listing, registration, qualification, consent, approval, or action
shall have been effected, obtained, or taken under conditions acceptable to the
Committee. Without limiting the generality of the foregoing, each Optionee or
his legal representative or beneficiary may also be required to give
satisfactory assurance that shares purchased upon exercise of an Option are
being purchased for investment and not with a view to distribution, and
certificates representing such shares may be legended accordingly.

          (l) Withholding and Use of Shares to Satisfy Tax Obligations. The
obligation of the Company to deliver shares of Common Stock upon the exercise of
any 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 tax laws, the Committee,

                                      -19-


in its discretion (and subject to such withholding rules ("Withholding Rules")
as shall be adopted by the Committee), may permit the Optionee to satisfy the
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 Optionee recognizes ordinary
income with respect to such exercise) (the "Determination Date"); provided,
however, that with respect to Optionees who are subject to section 16 of the
Exchange Act, any such amount of taxes required to be withheld automatically
shall be satisfied by withholding Common Stock or, in the discretion of the
Committee, by receipt of cash. 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 federal income tax withholding
requirements. In the event shares of Common Stock acquired under the exercise of
an ISO are used to satisfy such withholding requirement, such shares of Common
Stock must have been held by the Optionee for a period of not less than the
holding period described in section 422(a)(1) of the Code on the Determination
Date, or if such shares of Common Stock were acquired through exercise of an
NQSO or of an option under a similar plan, such option was granted to the
Optionee at least six months prior to the Determination Date.

                                      -20-


                                    SECTION 9

                               Capital Adjustments

                               -------------------

          The number of shares which may be issued under the Plan, the maximum
number of shares with respect to which Options may be granted to any Key
Employee under the Plan, both as stated in Section 4 hereof, and the number of
shares issuable upon exercise of outstanding Options under the Plan (as well as
the Option price per share under such outstanding Options), shall, subject to
the provisions of section 424(a) of the Code, be adjusted, as may be deemed
appropriate by the Committee, to reflect any stock dividend, stock split, share
combination, or similar change in the capitalization of the Company.

                  In the event of a corporate transaction (as that term is
described in section 424(a) of the Code and the Treasury Regulations issued
thereunder as, for example, a merger, consolidation, acquisition of property or
stock, separation, reorganization, or liquidation), each outstanding Option
shall be assumed by the surviving or successor corporation; provided, however,
that, in the event of a proposed corporate transaction, the Committee may
terminate all or a portion of the outstanding Options if it determines that such
termination is in the best interests of the Company. If the Committee decides to
terminate outstanding Options, the Committee shall give each Optionee holding an
outstanding Option to be terminated not less than seven days' notice prior to
any such termination by reason of

                                      -21-


such a corporate transaction, and any such Option which is to be so terminated
may be exercised (if and only to the extent that it is then exercisable) up to,
and including the date immediately preceding such termination. Further, as
provided in Section 8(d) hereof the Committee, in its discretion, may
accelerate, in whole or in part, the date on which any or all Options become
exercisable.

          The Committee also may, in its discretion, change the terms of any
outstanding Option to reflect any such corporate transaction, provided that, in
the case of ISOs, such change is excluded from the definition of a
"modification" under section 424(h) of the Code.

                                      -22-


                                   SECTION 10

                                  Acquisitions
                                  ------------

                  Notwithstanding any other provision of this Plan, Options may
be granted hereunder in substitution for options held by directors, key
employees, and associates of other corporations who are about to, or have,
become Key Employees or Associates of the Company or a Related Corporation as a
result of a merger, consolidation, acquisition of assets or similar transaction
by the Company or a Related Corporation. The terms, including the option price,
of the substitute options so granted may vary from the terms set forth in this
Plan to such extent as the Committee may deem appropriate to conform, in whole

or in part, to the provisions of the options in substitution for which they are
granted.

                                      -23-


                                   SECTION 11

                 Amendment or Replacement of Outstanding Options
                 -----------------------------------------------

          The Committee shall have the authority to effect, at any time and from
time to time, with the consent of the affected Optionees, the cancellation of
any or all outstanding Options under the Plan and to grant in substitution
therefor new Options under the Plan covering the same or a different number of
shares of Common Stock but having a per share purchase price not less than the
greater of par value or 100% of the Fair Market Value of a share of Common Stock
on the new date of the grant. The Committee may permit the voluntary surrender
of all or a portion of any Option to be conditioned upon the granting to the
Optionee under the Plan of a new Option for the same or a different number of
shares of Common Stock as the Option surrendered, or may require such voluntary
surrender as a condition precedent to a grant of a new Option to such Optionee.
Any new Option shall be exercisable at the price, during the period, and in
accordance with any other terms and conditions specified by the Committee at the
time the new Option is granted, all determined in accordance with the provisions
of the Plan without regard to the price, period of exercise, and any other terms
or conditions of the Option surrendered.

                                   SECTION 12

                     Amendment or Discontinuance of the Plan
                     ---------------------------------------

          (a) General. The Board from time to time may suspend

                                      -24-


or discontinue the Plan or amend it in any respect whatsoever, except that the
following amendments shall require shareholder approval (given in the manner set
forth in Subsection (b) below):

               (1)  Any amendment which would:

                    (A)  materially increase the benefits accruing to directors
and officers, within the meaning of 17 CFR ss. 240.16a-1(f) (hereinafter
referred to as "Officers"), under the Plan;

                    (B)  materially increase the number of shares of Common
Stock which may be issued to directors and Officers under the Plan; or

                    (C)  materially modify the requirements as to eligibility
for directors and Officers to participate in the Plan;


               (2)  With respect to ISOs, any amendment which would:

                    (A)  change the class of employees eligible to participate
in the Plan;

                    (B)  except as permitted under Section 9 hereof, increase
the maximum number of shares of Common Stock with respect to which ISOs may be
granted under the Plan; or

                    (C)  extend the duration of the Plan under Section 18 hereof
with respect to any ISOs granted hereunder;

               (3)  Any amendment which would require shareholder approval
pursuant to Treas. Reg. ss.1.162-27(e)(4)(vi), or any successor thereto.

                                      -25-


Notwithstanding the foregoing, no such suspension, discontinuance or amendment
shall materially impair the rights of any holder of an outstanding Option
without the consent of such holder.

          (b) Shareholder Approval Requirements. Shareholder approval must meet
the following requirements:

               (i) The approval of shareholders must be by a majority of the
          outstanding shares of Common Stock either (A) present, or represented,
          and entitled to vote at a meeting duly held in accordance with the
          applicable laws of the State of Delaware or (B) pursuant to written
          consent of shareholders in lieu of a meeting in accordance with the
          applicable laws of the State of Delaware; and

               (ii) The approval of shareholders must comply with all applicable
          provisions of the corporate charter, bylaws, and applicable state law
          prescribing the method and degree of shareholder approval required for
          the issuance of corporate stock or options. If the applicable state
          law does not prescribe a method and degree of shareholder approval in
          such case, the approval of shareholders must be effected:

                    (A) By a method and in a degree that would be treated as
               adequate under applicable state law in the case of an action
               requiring shareholder approval (i.e., an action on which
               shareholders would be entitled to vote if the action were taken
               at a duly held shareholders' meeting); or

                                      -26-


                    (B) By a majority of the votes cast at a duly held
               shareholders' meeting at which a quorum representing a majority
               of all outstanding voting stock is, either in person or by proxy,
               present and voting on the plan.

                                   SECTION 13


                                     Rights
                                     ------

          Neither the adoption of the Plan nor any action of the Board or the
Committee shall be deemed to give any individual any right to be granted an
Option, or any other right hereunder, unless and until the Committee shall have
granted such individual an Option, and then his rights shall be only such as are
provided by the Option Agreement.

          Any Option under the Plan shall not entitle the holder thereof to any
rights as a stockholder of the Company prior to the exercise of such Option and
the issuance of the shares pursuant thereto. Further, notwithstanding any
provisions of the Plan or the Option Agreement with an Optionee, the Company
shall have the right, in its discretion, to retire an Optionee at any time
pursuant to its retirement rules or otherwise to terminate his or her employment
or service at any time for any reason whatsoever.

                                      -27-


                                   SECTION 14

                     Indemnification of Board and Committee
                     --------------------------------------

          Without limiting any other rights of indemnification which they may
have from the Company and any Related Corporation, the members of the Board and
the members of the Committee shall be indemnified by the Company against all
costs and expenses reasonably incurred by them in connection with any claim,
action, suit, or proceeding to which they or any of them may be a party by
reason of any action taken or failure to act under, or in connection with, the
Plan, or any Option granted thereunder, and against all amounts paid by them in
settlement thereof (provided such settlement is approved by legal counsel
selected by the Company) or paid by them in satisfaction of a judgment in any
such action, suit, or proceeding, except a judgment based upon a finding of
willful misconduct or recklessness on their part. Upon the making or institution
of any such claim, action, suit, or proceeding, the Board or Committee member
shall notify the Company in writing, giving the Company an opportunity, at its
own expense, to handle and defend the same before such Board or Committee member
undertakes to handle it on his own behalf.

                                      -28-


                                   SECTION 15

                              Application of Funds
                              --------------------

          The proceeds received by the Company from the sale of Common Stock
pursuant to Options granted under the Plan shall be used for general corporate
purposes. Any cash received in payment for shares upon exercise of an Option to
purchase Common Stock shall be added to the general funds of the Company and

shall be used for its corporate purposes. Any Common Stock received in payment
for shares upon exercise of an Option to purchase Common Stock shall become
treasury stock.

                                   SECTION 16

                              Shareholder Approval
                              --------------------

          This Plan shall become effective as of March 22, 1996 (the date the
Plan was adopted by the Board); provided, however, that if the Plan is not
approved in the manner described in Section 12(b) within 12 months before or
after said date, the Plan and all Options granted hereunder shall be null and
void and no additional options shall be granted hereunder.

                                   SECTION 17

                        No Obligation to Exercise Option
                        --------------------------------

          The granting of an Option shall impose no obligation upon an Optionee
to exercise such Option.

                                      -29-


                                   SECTION 18

                               Termination of Plan
                               -------------------

          Unless earlier terminated as provided in the Plan, the Plan and all
authority granted hereunder shall terminate absolutely at 12:00 midnight on
March 21, 2006, which date is within ten years after the date the Plan was
adopted by the Board (or the date the Plan was approved by the shareholders of
the Company, whichever is earlier), and no Options hereunder shall be granted
thereafter. Nothing contained in this Section 18, however, shall terminate or
affect the continued existence of rights created under Options issued hereunder
and outstanding on March 21, 2006, which by their terms extend beyond such date.

                                   SECTION 19

                                  Governing Law
                                  -------------

          With respect to any ISOs granted pursuant to the Plan and the Option
Agreements thereunder, the Plan, such Option Agreements and any ISOs granted
pursuant thereto shall be governed by the applicable Code provisions to the
maximum extent possible. Otherwise, the laws of the state of Delaware shall
govern the operation of, and the rights of Optionees under, the Plan, the Option
Agreements and any Options granted thereunder.

                                      -30-

to have Stuart on board. We believe that his demonstrated leadership strengthens
our senior management team. Further, Stuart's experience at Goldman Sachs will
give Integra access to a considerable wealth of relationships and business
opportunities that will help us to continue to fulfill our mission.

"One of the founding visions of Integra is substantive rapid growth through
technology and business consolidation, and meaningful business alliances,"
continued Caruso. "We are convinced that to continue to implement this vision
properly in a rapidly changing medical industry, we must have successfully
demonstrated medical industry skills at the very top of the Company. We have
spent the past seven years building a purposeful infrastructure and we are now
turning our attention to completing the executive management team that will lead
us into the future."

Dr. Caruso added, "We already have in place an outstanding operating team for
our tissue regeneration business, led by the Company's Chief Operating Officer
and Vice Chairman, Dr. George W. McKinney. We believe Stuart's experience will
complement both Dr. McKinney's operations expertise and my own entrepreneurial
background. Mr. Essig has substantial expertise in negotiating corporate
alliances and in public company mergers and acquisitions. 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 build upon our and his relationships with the investment
community."

In accepting the appointment, Mr. Essig said, "The medical technology industry
is consolidating rapidly. Only companies that adapt quickly to the changing
marketplace will prosper. Integra already has a corporate culture that
successfully accepts rapid change. The Company is extremely well positioned
technologically with a pipeline of BioSmart(TM) implantable products for a
variety of surgical markets. The Company is already an emerging leader in
reaching the surgical skin business with its lead product, INTEGRA(TM)
Artificial Skin, and expects to initiate significant activities in the
neurosurgical market in 1998. Integra has additional products for the wound
care, dental, orthopedic, and cardiovascular markets. Working closely with Drs.
Caruso and McKinney, I expect to focus on acquisitions and alliances that will
improve the speed and likeliness of success in bringing these new products to
market. The Company has a number of significant initiatives underway in this
regard, which I look forward to bringing to fruition in the near future."

Mr. Essig has entered into a four-year employment contract with Integra under
which he will receive options for one million Integra common shares. He will
also receive a deferred payment consisting of two million Integra shares.
Integra expects to take a one-time, non-cash compensation charge of
approximately $6 million for this deferred payment in the fourth quarter of this
year. "We are pleased to have been able to work with Stuart to align his
compensation directly with the financial interests of our shareholders. Very
simply, as our stock rises, Mr. Essig's ultimate financial reward increases,"
said Dr. Caruso.

Integra LifeSciences Corporation is dedicated to the development and manufacture
of proprietary BioSmart(TM) absorbable materials-based therapeutic applications
and pharmacological products, which are designed to control the behavior of
cells within the patient's body to regenerate tissue that has been irreversibly
lost to disease, accident or surgery, or to prevent or cure diseases or
age-associated disorders. Integra(TM) Artificial Skin is the first of a series
of products that the Company is developing to regenerate a variety of body
tissues, including articular cartilage and peripheral nerves, which ordinarily
do not regenerate themselves.
