(the "Agreement");

(B) Pursuant to the Agreement NAPTAU was obligated, in part, to pay the sum of
USD$200,000 to Dennis on or before December 12,1995;

(C) By an agreement dated April 30, 1996, NAPTAU was granted an extension of the

payment by NAPTAU to Dennis of 100 ounces of raw gold from its share of the gold
produced from all of its placer mining operations in the Cariboo Mining Division
of British Columbia (the "Leases");

(E) By a Third Extension Agreement dated December 31,1997 the time for payment
of the money referred to in paragraph 2 was extended to December 3lst, 1998 and
the number of ounces of raw gold required to be paid was increased to 150 ounces
which was to be paid to Dennis from production from the Leases;

(F) For reasons known to Dennis, NAPTAU was unable to obtain sufficient
production of raw gold from the Leases in 1998 to meet its obligations to Dennis

(H) By a fourth Extension Agreement entered into on or about March 30, 1999, the
amount agreed to be paid by NAPTAU to Dennis in paragraph 2 was extended to the
31st day of December, 1999, and instead of the 150 ounces of raw gold to be paid
by NAPTAU to Dennis under the Third Extension Agreement it was agreed that
Naptau would pay Dennis 200 ounces of raw gold from its share of the gold
produced from the mining operations on the Mineral Tenure Lease.

Settlement Agreement.

                                  1999 STOCK OPTION PLAN

                                   Section 1

                                     Purpose

            This INTEGRA LIFESCIENCES HOLDINGS CORPORATION 1999 STOCK OPTION
PLAN (the "Plan") is intended to provide a means whereby Integra LifeSciences
Holdings Corporation (the "Company") may, through the grant of incentive stock
options and non-qualified stock options (collectively, "Options") to purchase
common stock of the Company, par value $0.01 per share ("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, any Related Corporation (as defined
below), or any affiliate of the Company or a Related Corporation.

            For purposes of the Plan, a "Related Corporation" shall mean either
a "subsidiary corporation" of the Company, as defined in section 424(f) of the
Internal Revenue Code of 1986, as amended ("Code"), or the "parent corporation"
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 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 does not qualify as an incentive stock option.

                                   Section 2

                                 Administration

            The Plan shall be administered by the Company's Stock Option
Committee (the "Committee"), which shall consist solely of not fewer than two
directors of the Company, who shall be appointed by, and shall serve at the
pleasure of, the Company's Board of Directors (the "Board") (taking into
consideration the rules under Section 16(b) of the Securities Exchange Act of
1934, as amended (the "Exchange Act") and the requirements of Section 1621(m) of
the Code). In the event a committee has not been established in accordance with
the preceding sentence, or cannot be constituted to vote on the grant of an
Option, the "Committee" shall consist of the entire 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.

            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, 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,

<PAGE>

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. Except as otherwise required by the bylaws of the Company or by
applicable law, 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.

                                   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 and non-managerial employees of the Company, a Related Corporation,
or an affiliate of the Company or a Related Corporation who are selected by the
Committee to receive Options. Key Employees of the Company and/or a Related
Corporation shall be eligible to receive ISOs and/or NQSOs. Key Employees of an
affiliate shall be eligible to receive only NQSOs.

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

                                   SECTION 4

                                      Stock

            The maximum number of shares of Common Stock that may be issued
under Options granted under the Plan shall be 2,000,000; 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 Options may be granted to a Key Employee.

<PAGE>

                                   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, and further
provided that Key Employees of an affiliate and Associates shall not be eligible
to receive ISOs under the Plan. A member of the Committee shall not participate
in a vote approving the grant of an Option to himself or herself to the extent
provided under the laws of Delaware governing corporate self-dealing. 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, a Related Corporation, or an affiliate 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.

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 quoted closing price on the last business day prior to
the specified date, if there is a market for the Common Stock on a registered
securities exchange or in an over-the-counter market;

                  (2) The weighted average of the quoted closing prices on the
nearest date before and the nearest date after the last business day prior to
the specified date, if there are no sales on such day but there are such sales
on dates within a reasonable period both before and after such 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

<PAGE>

                  (4) If (1) through (3) above are not applicable, 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 quoted closing prices on the
nearest date before and the nearest date after the last business day prior to
the specified date shall be weighted inversely by the respective numbers of
trading days between the dates of reported sales and such 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 of the Company or a Related Corporation 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.

                                   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 increase in the maximum number of shares which may be granted
to an individual in a one-year period pursuant to the Plan shall require such
shareholder approval as may be then required under the applicable rules and
regulations under the Code, and that with respect to any grant of an Option
which is intended to be an ISO 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 or
her 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 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 three 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 exercise date of
            any outstanding Options, in its discretion, if it deems such
            acceleration to be desirable.

            Any exercisable Option may be exercised 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 (except that, in the case of an exercise arrangement
approved by the Committee and described in Paragraph 2(B)(iv) below, payment may
be made as soon as practicable after the exercise). Only full

<PAGE>

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 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 and are used to pay the option
      price of an ISO, or if such shares of Common Stock were acquired through
      the exercise of an incentive stock option or non-qualified 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/or (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.

            (e) Termination of Employment or Service. If an Optionee's
employment by or service with the Company (and Related Corporations and
affiliates) 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 shall not be later than one year after the date of the
Optionee's termination of employment or service.

            (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
affiliates) 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

<PAGE>

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 shall not be
later than one year after the date of the Optionee's termination of employment
or service. In the event of the Optionee's legal disability, such Option may be
so exercised by the Optionee's legal representative.

            (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 affiliates), 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 later than one year after the date of
death.

            (h) Non-Transferability. No ISO and, except to the extent provided
in the related Option Agreement, no NQSO 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.

            (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 or her for such shares.

            (j) Ten Percent Shareholder. If, after applying the attribution
rules of Section 424(d) of the Code, 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.

            (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

<PAGE>

thereunder, or that action by the Company, its shareholders, or the Optionee
should be taken in order to obtain an exemption from any such requirement or to
continue any such listing, registration, or qualification, 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 or her legal representative or
beneficiary may also be required to give satisfactory assurance that such person
is an eligible purchaser under applicable securities laws, and 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, 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"). 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 income tax withholding
requirements. In the event shares of Common Stock acquired under the exercise of
an incentive stock option 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 a non-qualified stock option, such shares were acquired at least 12
months prior to the Determination Date.

                                   SECTION 9

                   Capital Adjustments; Corporate Transactions

            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 (such 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, effective upon the closing of the corporate
transaction, 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

<PAGE>

any such termination by reason of 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.

                                   SECTION 9A

                                Change in Control

            Notwithstanding any other provision of the Plan to the contrary, all
outstanding Options shall become fully vested and exercisable upon a Change in
Control of the Company. "Change in Control" shall mean any of the following
events:

            (a) An acquisition (other than directly from the Company) of any
voting securities of the Company ("Voting Securities") by any "Person" (as such
term is used for purposes of section 13(d) or 14(d) of the Exchange Act)
immediately after which such Person has "Beneficial Ownership" (within the
meaning of Rule 13d-3 promulgated under the Exchange Act) of 50% or more of the
combined voting power of all the then outstanding Voting Securities, other than
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;
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 9A shall not be a Change in Control under this
paragraph (a);

            (b) The individuals who, as of February 25, 1999, are members of the
Company's Board of Directors (the "Incumbent Board") cease for any reason to
constitute at least two-thirds of the Board of Directors; provided, however,
that if the election, or nomination for election by the shareholders, of any new
director was approved by a vote of at least two-thirds of the members of the
Board of Directors who constitute Incumbent Board members, such new directors
shall for all purposes be considered as members of the Incumbent Board as of
February 25, 1999; provided further, however, that no individual shall be
considered a member of the Incumbent Board if such individual initially assumed
office as a result of either an actual or threatened "Election Contest" (as
described in Rule 14a-11 promulgated under the Exchange Act) or other actual or
threatened solicitation of proxies or consents by or on behalf of a Person other
than the Board of Directors (a "Proxy Contest") including by reason of any
agreement intended to avoid or settle any Election Contest or Proxy Contest;

            (c) consummation by the Company of a reorganization, merger, or
consolidation or sale or other disposition of all or substantially all of the
assets of the Company or the acquisition of assets or stock of another entity (a
"Business Combination"), 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

<PAGE>

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; and (ii) 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;

            (d) approval by the shareholders of the Company of a complete
liquidation or dissolution of the Company; or

            (e) acceptance by shareholders of the Company of shares in a share
exchange if the shareholders of the Company immediately before such share
exchange do not own, directly or indirectly, immediately following such share
exchange more than 50% of the combined voting power of the outstanding Voting
Securities of the corporation resulting from such share exchange in
substantially the same proportion as their ownership of the Voting Securities
outstanding immediately before such share exchange.

                                   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.

                                   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.

<PAGE>

                                   SECTION 12

                     Amendment or Discontinuance of the Plan

            The Board from time to time may suspend or discontinue the Plan or,
subject to such shareholder approval as may be then required under the
applicable rules and regulations of the Code or rules of the exchange or market
on which the Common Stock is listed, may amend it in any respect whatsoever.
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.

                                   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 or her 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.

                                   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 (and any affiliate), 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.

<PAGE>

                                   SECTION 15

                              Application of Funds

            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. 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 February 25, 1999 (the date
the Plan was adopted by the Board); provided, however, that if the Plan is not
approved by the Company's shareholders 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.

                                   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
February 24, 2009, 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 February 24, 2009, 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.
