                              1997 INCENTIVE PLAN

        1. Purpose. The purpose of this Plan is to strengthen BioReliance
Corporation, a Delaware corporation (the "Company"), by providing an incentive
to its employees, officers, consultants and directors and thereby encouraging
them to devote their abilities and industry to the success of the Company's
business enterprise. It is intended that this purpose be achieved by extending
to employees, officers, consultants and directors of the Company and its
Subsidiaries a long-term incentive for high levels of performance and unusual
efforts through the grant of Incentive Stock Options, Nonqualified Stock
Options, Stock Appreciation Rights, Dividend Equivalent Rights, Performance
Awards and/or Restricted Stock (as each term is herein defined). After the
Effective Date of this Plan, no further awards shall be made under any of the
Former Plans. Each award outstanding under a Former Plan as of the Effective
Date of this Plan shall remain outstanding and continue to be subject to the
terms of the Former Plan and the award agreement under which such award was
granted. Each Share that is available for the granting of new awards under
either of the Former Plans as of the Effective Date of this Plan and each Share
that is the subject of an award under either of the Former Plans but is not
issued prior to the time that such award expires or otherwise terminates shall,
after the Effective Date of this Plan, not be available for the granting of
awards under either of the Former Plans, but shall instead be available for the
granting of Options under this Plan.

Securities then Beneficially Owned by members of the Knafel Family; provided,
however, in determining whether a Change in Control has occurred, Voting
Securities which are acquired in a "Non-Control Acquisition" (as defined below)
shall not constitute an acquisition which would cause a Change in Control. A
"Non-Control Acquisition" shall mean an acquisition by (A) an employee benefit
plan (or a trust forming a part thereof) maintained by (i) the Company or (ii)
any Subsidiary, (B) the Company or any Subsidiary, or (C) any Person in

two-thirds of the Board; provided, however, that if the election, or nomination
for election by the Company's stockholders, of any new director was approved by
a vote of at least two-thirds of the Incumbent Board, such new director shall,
for purposes of the Plan, be considered as a member of the Incumbent Board;
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

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 (a
"Proxy Contest") including by reason of any agreement intended to avoid or
settle any Election Contest or Proxy Contest; or

                 (3) Consummation of:

                     (A) A merger, consolidation or reorganization involving the
Company, unless

                         (i) the stockholders of the Company immediately before
such merger, consolidation or reorganization own, directly or indirectly,
immediately following such merger, consolidation or reorganization, more than

reorganization (the "Surviving Corporation") in substantially the same
proportion as their ownership of the Voting Securities immediately before such
merger, consolidation or reorganization;


                                      -3-


<PAGE>


                         (ii) the individuals who were members of the Incumbent
Board immediately prior to the execution of the agreement providing for such

maintained by the Company, the Surviving Corporation or any Subsidiary, or any
Person who, immediately prior to such merger, consolidation or reorganization
had Beneficial Ownership of twenty percent (20%) or more of the then outstanding
Voting Securities) has Beneficial Ownership of twenty percent (20%) or more of
the combined voting power of the Surviving Corporation's then outstanding voting
securities; and

                         (iv) a transaction described in clauses (i) through
(iii) shall herein be referred to as a "Non-Control Transaction";

                     (B) A complete liquidation or dissolution of the Company;
or

                     (C) An agreement for the sale or other disposition of all
or substantially all of the assets of the Company to any Person (other than a
transfer to a Subsidiary).

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur
solely because any Person (the "Subject Person") acquired Beneficial Ownership
of more than the permitted amount of the outstanding Voting Securities as a
result of the acquisition of Voting Securities by the Company which, by reducing
the number of Voting Securities outstanding, increases the proportional number
of shares beneficially owned by the Subject Person; provided, however, that if a
Change in Control would occur (but for the operation of this sentence) as a
result of the acquisition of Voting Securities by the Company, and after such
share acquisition by the Company, the Subject Person becomes the Beneficial
Owner of any additional Voting Securities which increases the percentage of the
then outstanding Voting Securities beneficially owned by the Subject Person,
then a Change in Control shall occur.

granted under the Plan and to determine the number of Stock Appreciation Rights,
Performance Awards, Shares of Restricted Stock and/or Dividend Equivalent Rights
to be granted pursuant to each Award, the terms and conditions of each Award,
including the restrictions or Performance Objectives relating to Awards and the
maximum value of any Award, and make any amendment or modification to any
Agreement consistent with the terms of the Plan;

                (c) accelerate a Discretionary Option or Award and to waive
restrictive conditions for a Discretionary Option or Award (including, without
limitation, any forfeiture conditions), in such circumstances as the Committee
deems appropriate, subject to any express limitations of the Plan, including,
without limitation, Section 16(b); provided, however, that nothing in this
Section 3.2(c) shall be construed to limit the Committee's authority under other
provisions of the Plan. In the case of any acceleration of a Discretionary
Option or Award after the attainment of the applicable Performance Objective(s),
the amount payable shall be discounted to its present value using an interest
rate equal to Moody's Average Corporate Bond Yield for the month preceding the
month in which such acceleration occurs. This paragraph shall not apply in
respect of a UK Approved Option;

                (d) to construe and interpret the Plan and the Options and
Awards granted hereunder and to establish, amend and revoke rules and
regulations for the administration of the Plan, including, without limitation,
correcting any defect or supplying any omission, or reconciling any
inconsistency in the Plan or in any Agreement, in the manner and to the extent
it shall deem necessary or advisable so that the Plan complies with applicable
law including Rule 16b-3 under the Exchange Act and the Code to the extent
applicable, and otherwise to make the Plan fully effective. All decisions and
determinations by the Committee in the exercise of this power shall be final,
binding and conclusive upon the Company, its Subsidiaries, the Optionees and
Grantees, and all other persons having any interest therein;

                (e) to determine the duration and purposes for leaves of absence
which may be granted to an Optionee or Grantee on an individual basis without
constituting a termination of employment or service for purposes of the Plan;


                                      -10-


<PAGE>


                (f) to exercise its sole discretion with respect to the powers
and rights granted to it as set forth in the Plan; and

                (g) generally, to exercise such powers and to perform such acts
as are deemed necessary or advisable to promote the best interests of the
Company with respect to the Plan.

        4. Stock Subject to the Plan.

           4.1 The maximum number of Shares that may be made the subject of
Options and Awards granted under the Plan is 500,000 Shares, plus the aggregate
number of Shares that would have been available for new awards under the Former
Plans after the Effective Date of this Plan (but for the prospective termination
of the Former Plans), including the Shares that were available for new grants
under each of the Former Plans as of the Effective Date of this Plan and the
Shares that are subject to awards granted under either of the Former Plans which
Shares are not issued prior to the expiration or other termination of such
awards (including Shares subject to awards that expire or terminate after the
expiration of the term of a Former Plan); provided, however, that in the
aggregate, not more than one-third of the number of allotted Shares may be made
the subject of Restricted Stock Awards under Section 10 of the Plan; and
provided, further, that the aggregate Fair Market Value of the Shares with
respect to which Incentive Stock Options granted under the Plan become
exercisable for the first time by an Optionee during any calendar year shall not
exceed $100,000. Upon a Change in Capitalization, the maximum number of Shares
referred to in the preceding sentence shall be adjusted in number and kind
pursuant to Section 13. The Company shall reserve for the purposes of the Plan,
out of its authorized but unissued Shares or out of Shares held in the Company's
treasury, or partly out of each, such number of Shares as shall be determined by
the Board.

           4.2 Upon the granting of an Option or an Award, the number of Shares
available under Section 4.1 for the granting of further Options and Awards shall
be reduced as follows:

               (a) In connection with the granting of an Option or an Award
(other than the granting of a Performance Unit denominated in dollars), the
number of Shares shall be reduced by the number of Shares in respect of which
the Option or Award is granted or denominated.

               (b) In connection with the granting of a Performance Unit
denominated in dollars, the number of Shares shall be reduced by an amount equal
to the quotient of (i) the dollar amount in which the Performance Unit is
denominated, divided by (ii) the Fair Market Value of a Share on the date the
Performance Unit is granted.

           4.3 Whenever any outstanding Option or Award or portion thereof
expires, is canceled or is otherwise terminated for any reason without having
been exercised or payment having been made in respect of the entire Option or
Award (including any


                                      -11-

<PAGE>


outstanding Options under any of the Former Plans), the Shares allocable to the
expired, canceled or otherwise terminated portion of the Option or Award may
again be the subject of Options or Awards granted hereunder.

        5. Option Grants for Eligible Individuals.

           5.1 Authority of Committee. (a) Subject to the provisions of the
Plan, the Committee shall have full and final authority to select those Eligible
Individuals who will receive Discretionary Options, and the terms and conditions
of the grant to such Eligible Individuals shall be set forth in an Agreement.
The terms and conditions of UK Approved Options shall be set forth in a
certificate executed as a deed by the Company and UK Approved Options may only
be granted to Eligible Employees.

               (b) Notwithstanding any provision of this Section 5, any
Discretionary Option granted under this Section 5 to an Eligible Individual who
is a Non-Employee Director shall be governed by the duration and termination
provisions set forth in Sections 6.4(a) - (e) of the Plan or such other duration
and termination provisions as determined by the Committee and set forth in an
Agreement.

           5.2 Purchase Price. The purchase price (which may be greater than,
less than or equal to the Fair Market Value on the Date of Grant) or the manner
in which the purchase price is to be determined for Shares under each
Discretionary Option shall be determined by the Committee and set forth in the
Agreement; provided, however, that the purchase price per Share under each
Incentive Stock Option shall not be less than 100% of the Fair Market Value of a
Share on the Date of Grant (110% in the case of an Incentive Stock Option
granted to a Ten-Percent Stockholder).

               (a) The purchase price of a Share under a UK Approved Option
shall be not less than:

                   (i) its market value as determined by the Committee in
accordance with the provisions of Part VIII of the Taxation of Chargeable Gains
Act 1992 of the United Kingdom and approved prior to the grant of the related UK
Approved Option by the Shares Valuation Division of the UK Inland Revenue; or

                   (ii) its nominal amount or (when applicable) such price as
from time to time adjusted pursuant to the Plan.

               (b) No UK Approved Option shall be granted under this Plan to an
Eligible Employee if the aggregate purchase price of the Shares comprised
therein, when added to the aggregate of the amounts for which shares of the
Company may be acquired under any subsisting UK Approved Options granted to him
under the Plan or any other scheme (not being a savings-related share option
scheme) approved under Schedule 9 to the Taxes Act and established by the
Company or a Subsidiary, would exceed, or further exceed,


                                      -12-


<PAGE>


pounds sterling 30,000 or such other limit as may apply from time to time under
paragraph 28 of Schedule 9 to the Taxes Act (the "Limit"). For the purposes of
determining whether an Option is subject to the Limit, Options which fell to be
treated under the provisions of Section 115 of the Finance Act 1996 of the
United Kingdom as unapproved options shall be treated as having been granted
under a scheme other than one which is approved under Schedule 9 to the Taxes
Act.

           5.3 Maximum Duration. Discretionary Options granted hereunder shall
be for such term as the Committee shall determine, provided that an Incentive
Stock Option shall not be exercisable after the expiration of ten (10) years
from the date it is granted (five (5) years in the case of an Incentive Stock
Option granted to a Ten-Percent Stockholder) and a Nonqualified Stock Option
shall not be exercisable after the expiration of ten (10) years from the Date of
Grant. The Committee may, subsequent to the granting of any Discretionary Option
(other than a UK Approved Option), extend the term thereof, but in no event
shall the term as so extended exceed the maximum term provided for in the
preceding sentence.

           5.4 Exercisability. Subject to Sections 5.5 and 7.3, each
Discretionary Option shall become exercisable in such installments (which need
not be equal) and at such times as may be designated by the Committee and set
forth in the Agreement. To the extent not exercised, installments shall
accumulate and be exercisable, in whole or in part, at any time after becoming
exercisable, but not later than the date the Discretionary Option expires. No UK
Approved Option shall become exercisable in any circumstances by an Optionee who
is at the time of such intended exercise an Excluded Person.

           5.5 Termination. Except as provided in Sections 5.1(b) and 12, and
unless otherwise provided by the Committee, in its sole discretion, in the
applicable Agreement, the following provisions shall apply to Discretionary
Options upon a Termination of Employment:

           (a) Subject to Section 5.3 and except as provided in Section 5.5(d),
unless otherwise determined by the Committee at the time of grant (and set forth
in the applicable Agreement) or at a later date, except in the case of
Disability, retirement on or after the Optionee's Normal Retirement Date and
death as provided in Sections 5.5(b) and 5.5(c) below, if an Optionee of a
Discretionary Option has a Termination of Employment with the Company or a
Subsidiary, any unexercised Discretionary Option held by such Optionee shall
expire ninety (90) days after the Optionee has a Termination of Employment for
any reason other than a termination for Cause, and such Discretionary Option may
only be exercised by the Optionee or his or her Beneficiary to the extent that
the Discretionary Option or a portion thereof was exercisable on the date of
Termination of Employment; provided, however, that no Discretionary Option may
be exercised after the expiration date specified for the particular
Discretionary Option in the Discretionary Option grant. If the Optionee's
Termination of Employment arises as a result of a termination for Cause, then,
unless the Committee determines otherwise at the time of the Termination of
Employment,



                                      -13-


<PAGE>

any unexercised Options held by such Optionee shall terminate and expire
concurrently with the Optionee's Termination of Employment.

           (b) Subject to Section 5.3, unless otherwise determined by the
Committee at the time of grant (and set forth in the applicable Agreement) or at
a later date, if an Optionee becomes disabled within the meaning of Section 2.17
hereof or retires on or after the Optionee's Normal Retirement Date, any
unexercised Discretionary Option held by such disabled or retired Optionee shall
expire one (1) year after the Disability Date or date of Termination of
Employment by reason of retirement, as the case may be, and such Option may only
be exercised by the Optionee or his or her Beneficiary to the extent that the
Discretionary Option or a portion thereof was exercisable on the Disability Date
or the date of Termination of Employment by reason of retirement, as the case
may be; provided, however, no Discretionary Option may be exercised after the
expiration date specified for the particular Discretionary Option in the
Discretionary Option grant.

           (c) Subject to Section 5.3, unless otherwise determined by the
Committee at the time of grant (and set forth in the applicable Agreement) or at
a later date, if an Optionee dies while still employed by the Company, the
Options which the Optionee was entitled to exercise on the date of the
Optionee's death may be exercised at any time after the Optionee's death by the
Optionee's Beneficiary; provided, however, that no Option may be exercised after
the earlier of: (i) one (1) year after the Optionee's death or (ii) the
expiration date specified for the particular Option in the Option Agreement. If
an Optionee dies after his or her Termination of Employment, then the Options
which the Optionee was entitled to exercise on the date of the Optionee's death
may be exercised by his or her Beneficiary within the period specified in
Sections 5.5(a) or 5.5(b), as the case may be.

           (d) Subject to Section 5.3, upon an Optionee's Termination of
Employment following a Change in Control, each Option held by the Optionee that
was exercisable as of the date of such Termination of Employment shall remain
exercisable for a period ending not before the earlier of (A) the first
anniversary of the Termination of Employment or (B) the expiration of the stated
term of the Option.

           5.6 Modification. No modification of a Discretionary Option shall
adversely alter or impair any rights or obligations under the Discretionary
Option without the Optionee's consent.

        6. Automatic Option Grants for Non-Employee Directors, Committee
Chairpersons and Scientific Advisory Board Members.

           6.1 Grant. Automatic Options shall be granted (i) to each
Non-Employee Director who becomes a member of the Board after April 24, 1997
upon election or appointment, (ii) to each Non-Employee Director who is a member
of the Board, (iii) to each Non-Employee Director who is the chairperson of a
committee of the Board, (iv) to each member of the Scientific Advisory Board
who becomes a member of the Scientific Advisory



                                      -14-


<PAGE>


Board after April 24, 1997 upon election or appointment and (v) to each member
of the Scientific Advisory Board, as follows:

               (a) Initial Grant. Each Non-Employee Director who becomes a
Director after April 24, 1997 shall, upon becoming a Director, be granted an
Automatic Option in respect of 2,000 Shares and each member of the Scientific
Advisory Board who becomes a member of the Scientific Advisory Board after April
24, 1997 shall, upon becoming a member of the Scientific Advisory Board, be
granted an Automatic Option in respect of 1,000 Shares.

               (b) Annual Grants to Non-Employee Directors and Members of the
Scientific Advisory Board. Each Non-Employee Director shall be granted an
Automatic Option in respect of 1,000 Shares annually on the first Business Day
on or after January 1 of each calendar year that the Plan is in effect provided
that the Non-Employee Director is a Director on such date and each member of the
Scientific Advisory Board shall be granted an Automatic Option in respect of 500
Shares annually on the first Business Day on or after January 1 of each calendar
year that the Plan is in effect provided that the member of the Scientific
Advisory Board is a member on such date; provided, however, that a Director or
member of the Scientific Advisory Board shall not be entitled to receive an
annual grant pursuant to this Section 6.1(b) for the calendar year in which such
Director or member of the Scientific Advisory Board is first elected or
appointed to the Board or to the Scientific Advisory Board, as the case may be.

               (c) Annual Grants to Committee Chairpersons. Each Non-Employee
Director who, in accordance with the Bylaws of the Company, serves as a
chairperson of any committee of the Board as of the first Business Day on or
after January 1 of each calendar year that the Plan is in effect shall, on such
date, be granted an Automatic Option in respect of 500 Shares.

               (d) Terms and Conditions. All Automatic Options granted pursuant
to this Section 6 shall be evidenced by an Agreement containing such other terms
and conditions not inconsistent with the provisions of this Plan as determined
by the Board; provided, however, that such terms shall not vary the price,
amount or timing of the Automatic Options provided under this Section 6,
including provisions dealing with vesting, forfeiture and termination of such
Automatic Options.

           6.2 Purchase Price. The purchase price for Shares under each
Automatic Option shall be equal to 100% of the Fair Market Value of such Shares
on the Date of Grant.

           6.3 Vesting. Subject to Sections 6.4 and 7.3, each Automatic Option
granted after May 21, 1998 shall vest in one-third increments on each of the
first three anniversaries of the Grant Date; provided, however, that the
Optionee continues to serve as a Director or member of the Scientific Advisory
Board (as the case may be) as of such date. If an Optionee ceases to serve as a
Director or member of the Scientific Advisory Board (as


                                      -15-


<PAGE>

the case may be) for any reason, the Optionee shall have no rights with respect
to any Automatic Option (or portion thereof) which has not then vested pursuant
to the preceding sentence and the Optionee shall automatically forfeit any
Automatic Option (or portion thereof) which remains unvested.

           6.4 Duration. Each Automatic Option (and, with respect to
Non-Employee Directors, each Discretionary Option) shall terminate on the date
which is the tenth anniversary of the Date of Grant, unless terminated earlier
as follows:

               (a) If an Optionee's service as a Director or member of the
Scientific Advisory Board terminates for any reason other than Disability, death
or Cause, the Optionee may for a period of three (3) months after such
termination exercise his or her Option to the extent, and only to the extent,
that such Option or portion thereof was vested and exercisable as of the date
the Optionee's service as a Director or member of the Scientific Advisory Board
terminated, after which time the Option shall automatically terminate in full.

               (b) If an Optionee's service as a Director or member of the
Scientific Advisory Board terminates by reason of the Optionee's resignation or
removal due to Disability, the Optionee may, for a period of one (1) year after
such termination, exercise his or her Option to the extent, and only to the
extent, that such Option or portion thereof was vested and exercisable, as of
the date the Optionee's service as Director or member of the Scientific Advisory
Board terminated, after which time the Option shall automatically terminate in
full.

               (c) If an Optionee's service as a Director or member of the
Scientific Advisory Board terminates for Cause, the Option granted to the
Optionee hereunder shall immediately terminate in full and no rights thereunder
may be exercised.

               (d) If an Optionee dies while a Director or member of the
Scientific Advisory Board or within three (3) months after termination of
service as a Director or member of the Scientific Advisory Board as described in
clause (a) of this Section 6.4 or within twelve (12) months after termination of
service as a Director or member of the Scientific Advisory Board as described in
clause (b) of this Section 6.4, the Option granted to the Optionee may be
exercised at any time within twelve (12) months after the Optionee's death by
the person or persons to whom such rights under the Option shall pass by will,
or by the laws of descent or distribution, after which time the Option shall
terminate in full; provided, however, that an Option may be exercised to the
extent, and only to the extent, that the Option or portion thereof was
exercisable on the date of death or earlier termination of the Optionee's
services as a Director or member of the Scientific Advisory Board.

               (e) In the event an Optionee's service as a Director or member of
the Scientific Advisory Board of the Company is terminated by the Company
following a Change in Control, each Option held by the Optionee that was
exercisable as of the date of termination of the Optionee's service shall remain
exercisable for a period ending not before



                                      -16-


<PAGE>


the earlier of (A) the first anniversary of the termination of the Optionee's
service as a Director or member of the Scientific Advisory Board or (B) the
expiration of the stated term of the Option.

        7. Terms and Conditions Applicable to All Options.

           7.1 Method of Exercise.

               (a) The exercise of an Option shall be made only by a written
notice delivered in person or by mail to the Secretary of the Company at the
Company's principal executive office, specifying the number of Shares to be
purchased and accompanied by payment therefor and otherwise in accordance with
the Agreement pursuant to which the Option was granted. The purchase price for
any Shares purchased pursuant to the exercise of an Option shall be paid, as
determined by the Committee in its sole discretion, in either of the following
forms (or any combination thereof): (i) cash or (ii) the transfer of Shares to
the Company upon such terms and conditions as determined by the Committee. In
addition, both Discretionary Options and Automatic Options may be exercised
through a registered broker-dealer pursuant to such cashless exercise procedures
(other than Share withholding) which are, from time to time, deemed acceptable
by the Committee. Any Shares transferred to the Company (or withheld upon
exercise) as payment of the purchase price under an Option shall be valued at
their Fair Market Value on the day preceding the date of exercise of such
Option. The Optionee shall deliver the Agreement evidencing the Option to the
Secretary of the Company who shall endorse thereon a notation of such exercise
and return such Agreement to the Optionee. No fractional Shares (or cash in lieu
thereof) shall be issued upon exercise of an Option and the number of Shares
that may be purchased upon exercise shall be rounded to the nearest number of
whole Shares. Notwithstanding anything to the contrary contained herein, payment
on exercise of UK Approved Options shall be made only in cash.

               (b) If the Fair Market Value of the Shares with respect to which
the Option is being exercised exceeds the exercise price of such Option, an
Optionee may, instead of exercising an Option as provided in Section 7.1(a),
request that the Committee authorize payment to the Optionee of the difference
between the Fair Market Value of part or all of the Shares which are the subject
of the Option and the exercise price of the Option, such difference to be
determined as of the date the Committee receives the request from the Optionee.
The Committee, in its sole discretion, may grant or deny such a request from an
Optionee with respect to part or all of the Shares as to which the Option is
then exercisable and, to the extent granted, shall direct the Company to make
the payment to the Optionee either in cash or in Shares or in any combination
thereof; provided, however, that payment in Shares shall be made based upon the
Fair Market Value of Shares as of the date the Committee received the request
from the Optionee. An Option shall be deemed to have been exercised and shall be
canceled to the extent that the Committee grants a request pursuant to this
Section 7.1(b). The provisions of this paragraph shall not apply to holders of
UK Approved Options.


                                      -17-


<PAGE>


           7.2 Rights of Optionees. No Optionee shall be deemed for any purpose
to be the owner of any Shares subject to any Option unless and until (i) the
Option shall have been exercised pursuant to the terms thereof, (ii) the Company
shall have issued and delivered Shares to the Optionee, and (iii) the Optionee's
name shall have been entered as a stockholder of record on the books of the
Company. Thereupon, the Optionee shall have full voting, dividend and other
ownership rights with respect to such Shares, subject to such terms and
conditions as may be set forth in the applicable Agreement. The preceding
sentence shall not apply to any Optionee holding a UK Approved Option. If under
the terms of a resolution passed or an announcement made by the Company prior to
the date of exercise of a UK Approved Option, a dividend is to be or is proposed
to be paid to holders of Shares by reference to a record date after such date of
exercise, any Shares to be issued upon such exercise of a UK Approved Option
will not rank for such dividend. Subject as aforesaid, the Shares so to be
issued shall be identical and rank pari passu in all respects with the fully
paid Shares then in issue.

           7.3 Effect of Change in Control. In the event of a Change in Control,
all Options outstanding on the date of such Change in Control shall become
immediately and fully exercisable. In addition, to the extent set forth in an
Agreement evidencing the grant of a Discretionary Option, an Optionee will be
permitted to surrender to the Company for cancellation within sixty (60) days
after such Change in Control any Discretionary Option or portion of a
Discretionary Option to the extent not yet exercised and the Optionee will be
entitled to receive a cash payment in an amount equal to the excess, if any, of
(x) (A) in the case of a Nonqualified Stock Option, the greater of (1) the Fair
Market Value, on the date preceding the date of surrender, of the Shares subject
to the Discretionary Option or portion thereof surrendered or (2) the Adjusted
Fair Market Value of the Shares subject to the Discretionary Option or portion
thereof surrendered or (B) in the case of an Incentive Stock Option, the Fair
Market Value, on the date preceding the date of surrender, of the Shares subject
to the Discretionary Option or portion thereof surrendered, over (y) the
aggregate purchase price for such Shares under the Discretionary Option or
portion thereof surrendered.

        8. Stock Appreciation Rights. The Committee may in its sole discretion,
either alone or in connection with the grant of a Discretionary Option, grant
Stock Appreciation Rights in accordance with the Plan, the terms and conditions
of which shall be set forth in an Agreement. If granted in connection with an
Option, a Stock Appreciation Right shall cover the same Shares covered by the
Option (or such lesser number of Shares as the Committee may determine) and
shall, except as provided in this Section 8, be subject to the same terms and
conditions as the related Option.

           8.1 Time of Grant. A Stock Appreciation Right may be granted (i) at
any time if unrelated to an Option, or (ii) if related to an Option, either at
the time of grant, or at any time thereafter during the term of the Option.


                                      -18-


<PAGE>


           8.2 Stock Appreciation Right Related to an Option.

               (a) Exercise. Subject to Section 8.8, a Stock Appreciation Right
granted in connection with an Option shall be exercisable at such time or times
and only to the extent that the related Options are exercisable (including,
without limitation, exercisability upon Termination of Employment), and will not
be transferable except to the extent the related Option may be transferable. A
Stock Appreciation Right granted in connection with an Incentive Stock Option
shall be exercisable only if the Fair Market Value of a Share on the date of
exercise exceeds the purchase price specified in the related Incentive Stock
Option Agreement.

               (b) Treatment of Related Options and Stock Appreciation Rights
Upon Exercise. Upon the exercise of a Stock Appreciation Right granted in
connection with an Option, the Option shall be canceled to the extent of the
number of Shares as to which the Stock Appreciation Right is exercised, and upon
the exercise of an Option granted in connection with a Stock Appreciation Right,
the Stock Appreciation Right shall be canceled to the extent of the number of
Shares as to which the Option is exercised or surrendered.

           8.3 Stock Appreciation Right Unrelated to an Option.

               (a) Terms. Stock Appreciation Rights unrelated to Options shall
contain such terms and conditions as to exercisability (subject to Sections
8.3(b) and 8.8), vesting and duration as the Committee shall determine, but in
no event shall they have a term of greater than ten (10) years.

               (b) Termination. Except as provided in Section 8.8 and subject to
Section 8.3(a), and unless otherwise provided by the Committee, in its sole
discretion, in the applicable Agreement, upon a Grantee's Termination of
Employment or, in the case of a Non-Employee Director, termination of service as
a director, a Stock Appreciation Right shall be exercisable by the Grantee to
the same extent that a Discretionary Option would be exercisable by an Optionee
upon the Optionee's Termination of Employment under the provisions of Sections
5.5(a) through (d) (or, as applicable for Non-Employee Directors, Section 6.4);
provided, however, no Stock Appreciation Right may be exercised after the
expiration date specified for the particular Stock Appreciation Right in the
applicable Agreement.

           8.4 Amount Payable. Upon exercise of a Stock Appreciation Right, the
Grantee shall be entitled to receive an amount determined by multiplying (x) the
excess of the Fair Market Value of a Share on the date preceding the date of
exercise of such Stock Appreciation Right over (A) in the case of a Stock
Appreciation Right related to an Option, the per Share purchase price under the
related option or (B) in the case of a Stock Appreciation Right unrelated to an
Option, the Fair Market Value of a Share on the date the Stock Appreciation
Right was granted, by (y) the number of Shares as to which the Stock
Appreciation Right is being exercised. Notwithstanding the foregoing, the
Committee may



                                      -19-


<PAGE>



limit in any manner the amount payable with respect to any Stock Appreciation
Right by including such a limit in the Agreement evidencing the Stock
Appreciation Right at the time it is granted.

           8.5 Method of Exercise. Stock Appreciation Rights shall be exercised
by a Grantee only by a written notice delivered in person or by mail to the
Secretary of the Company at the Company's principal executive office, specifying
the number of Shares with respect to which the Stock Appreciation Right is being
exercised. If requested by the Committee, the Grantee shall deliver the
Agreement evidencing the Stock Appreciation Right being exercised and the
Agreement evidencing any related Option to the Secretary of the Company who
shall endorse thereon a notation of such exercise and return such Agreement to
the Grantee.

           8.6 Form of Payment. Payment of the amount determined under Section
8.4 may be made in the sole discretion of the Committee solely in whole Shares
in a number determined at their Fair Market Value on the date preceding the date
of exercise of the Stock Appreciation Right, or solely in cash, or in a
combination of cash and Shares. If the Committee decides to make full payment in
Shares and the amount payable results in a fractional Share, payment for the
fractional Share will be made in cash.

           8.7 Modification. No modification of an Award shall adversely alter
or impair any rights or obligations under the Agreement without the Grantee's
consent.

           8.8 Effect of Change in Control. In the event of a Change in Control,
all Stock Appreciation Rights shall become immediately and fully exercisable. In
addition, to the extent set forth in an Agreement evidencing the grant of a
Stock Appreciation Right (but not with respect to any Stock Appreciation Right
granted in connection with an Incentive Stock Option), a Grantee will be
permitted to surrender to the Company for cancellation within sixty (60) days
after such Change in Control any Stock Appreciation Right or portion of a Stock
Appreciation Right to the extent not yet exercised and the Grantee will be
entitled to receive a payment from the Company in cash or Shares, in either
case, with a value equal to the excess, if any, of (A) the Adjusted Fair Market
Value, on the date preceding the date of exercise, of the Shares over (B) the
aggregate Fair Market Value, on the date the Stock Appreciation was granted, of
the Shares subject to the Stock Appreciation Right or portion thereof exercised.

        9. Dividend Equivalent Rights. Dividend Equivalent Rights may be granted
to Eligible Individuals in tandem with an Option or Award. The terms and
conditions (including, without limitation, terms and conditions relating to a
Change in Control) applicable to each Dividend Equivalent Right shall be
specified in the Agreement under which the Dividend Equivalent Right is granted.
Amounts payable in respect of Dividend Equivalent Rights may be payable
currently or deferred until the lapsing of restrictions on such Dividend
Equivalent Rights or until the vesting, exercise, payment, settlement or other
lapse of restrictions on the Option or Award to which the Dividend Equivalent
Rights relate.


                                      -20-


<PAGE>



In the event that the amount payable in respect of Dividend Equivalent Rights
are to be deferred, the Committee shall determine whether such amounts are to be
held in cash or reinvested in Shares or deemed (notionally) to be reinvested in
Shares. If amounts payable in respect of Dividend Equivalent Rights are to be
held in cash, there may be credited at the end of each year (or portion thereof)
interest on the amount of the account at the beginning of the year at a rate per
annum as the Committee, in its sole discretion, may determine. Dividend
Equivalent Rights may be settled in cash or Shares or a combination thereof, in
a single installment or multiple installments. With respect to Dividend
Equivalent Rights granted in tandem with an Option, the Agreement may provide
that the Optionee may elect to have amounts payable in respect of such Dividend
Equivalent Rights applied against the exercise price of such Option. To the
extent necessary for any Dividend Equivalent Right intended to qualify as
performance-based compensation under Section 162(m) of the Code to so qualify,
the terms and conditions of the Dividend Equivalent Right shall be such that
payment of the Dividend Equivalent Right is contingent upon the attainment of
specified Performance Objectives within the Performance Cycle, as provided for
in Section 11, and such Dividend Equivalent Right shall be treated as a
Performance Award for purposes of Sections 11 and 16(b).

        10. Restricted Stock.

            10.1 Grant. The Committee may grant Awards to Eligible Individuals
of Restricted Stock, which shall be evidenced by an Agreement between the
Company and the Grantee. Each Agreement shall contain such restrictions, terms
and conditions as the Committee may, in its sole discretion, determine and
(without limiting the generality of the foregoing) such Agreements may require
that an appropriate legend be placed on Share certificates. Awards of Restricted
Stock shall be subject to the terms and provisions set forth below in this
Section 10.

            10.2 Rights of Grantee. Shares of Restricted Stock granted pursuant
to an Award hereunder shall be issued in the name of the Grantee as soon as
reasonably practicable after the Date of Grant provided that the Grantee has
executed an Agreement evidencing the Award, the appropriate blank stock powers
and, in the sole discretion of the Committee, an escrow agreement and any other
documents which the Committee may require as a condition to the issuance of such
Shares. If a Grantee shall fail to execute the Agreement evidencing a Restricted
Stock Award, the appropriate blank stock powers and, in the sole discretion of
the Committee, an escrow agreement and any other documents which the Committee
may require within the time period prescribed by the Committee at the time the
Award is granted, the Award shall be null and void. At the sole discretion of
the Committee, Shares issued in connection with a Restricted Stock Award shall
be deposited together with the stock powers with an escrow agent (which may be
the Company) designated by the Committee. Unless the Committee determines
otherwise and as set forth in the Agreement, upon delivery of the Shares to the
escrow agent, the Grantee shall have all of the rights of a stockholder with
respect to such Shares, including the right to vote the Shares and to receive
all dividends or other distributions paid or made with respect to the Shares.


                                      -21-


<PAGE>


            10.3 Non-transferability. Until all restrictions upon the Shares of
Restricted Stock awarded to a Grantee shall have lapsed in the manner set forth
in Section 10.4, such Shares shall not be sold, transferred or otherwise
disposed of and shall not be pledged or otherwise hypothecated, nor shall they
be delivered to the Grantee.

            10.4 Lapse of Restrictions.

                 (a) Generally. Subject to Section 10.4(b), restrictions upon
Shares of Restricted Stock awarded hereunder shall lapse at such time or times
and on such terms and conditions as the Committee may determine. The Agreement
evidencing the Award shall set forth any such restrictions.

                 (b) Effect of Change in Control. Unless the Committee shall
determine otherwise at the time of the grant of an Award of Restricted Stock,
the restrictions upon Shares of Restricted Stock shall lapse upon a Change in
Control. The Agreement evidencing the Award shall set forth any such provisions.

            10.5 Terms of Restricted Stock.

                 (a) Forfeiture of Restricted Stock. Subject to Sections 10.4(b)
and 10.5(b), all Restricted Stock shall be forfeited and returned to the Company
and all rights of the Grantee with respect to such Restricted Stock shall
terminate unless the Grantee continues in the service of the Company as an
employee or director until the expiration of the forfeiture period for such
Restricted Stock and satisfies any and all other conditions set forth in the
Agreement. The Committee, in its sole discretion, shall determine the forfeiture
period (which may, but need not, lapse in installments) and any other terms and
conditions applicable with respect to any Restricted Stock Award.

                 (b) Waiver of Forfeiture Period. Notwithstanding anything
contained in this Section 10 to the contrary, the Committee may, in its sole
discretion, waive the forfeiture period and any other conditions set forth in
any Agreement under appropriate circumstances (including, without limitation,
the death, Disability or retirement of the Grantee or a material change in
circumstances arising after the Date of Grant) and subject to such terms and
conditions (including, without limitation, forfeiture of a proportionate number
of the Restricted Stock) as the Committee shall deem appropriate, provided that
the Grantee shall at that time have completed at least one (1) year of
employment or service after the Date of Grant.

            10.6 Modification or Substitution. Subject to the terms of the Plan,
including, without limitation, Section 16(b), the Committee may modify
outstanding Awards of Restricted Stock or accept the surrender of outstanding
Shares of Restricted Stock (to the extent the restrictions on such Shares have
not yet lapsed) and grant new Awards in substitution for them. Notwithstanding
the foregoing, no modification of an Award shall adversely alter or impair any
rights or obligations under the Agreement without the Grantee's consent.


                                      -22-

<PAGE>


            10.7 Treatment of Dividends. At the time an Award of Shares of
Restricted Stock is granted, the Committee may, in its sole discretion,
determine that the payment to the Grantee of dividends, or a specified portion
thereof, declared or paid on such Shares by the Company shall be (i) deferred
until the lapsing of the restrictions imposed upon such Shares and (ii) held by
the Company for the account of the Grantee until such time. In the event that
dividends are to be deferred, the Committee shall determine whether such
dividends are to be reinvested in Shares (which shall be held as additional
Shares of Restricted Stock) or held in cash. If deferred dividends are to be
held in cash, there may be credited at the end of each year (or portion thereof)
interest on the amount of the account at the beginning of the year at a rate per
annum as the Committee, in its sole discretion, may determine. Payment of
deferred dividends in respect of Shares of Restricted Stock (whether held in
cash or as additional Shares of Restricted Stock), together with interest
accrued thereon, if any, shall be made upon the lapsing of restrictions imposed
on the Shares in respect of which the deferred dividends were paid, and any
dividends deferred (together with any interest accrued thereon) in respect of
any Shares of Restricted Stock shall be forfeited upon the forfeiture of such
Shares.

            10.8 Delivery of Shares. Upon the lapse of the restrictions on
Shares of Restricted Stock, the Committee shall cause a stock certificate to be
delivered to the Grantee with respect to such Shares, free of all restrictions
hereunder.

        11. Performance Awards.

            11.1 (a) Performance Objectives. Performance Objectives for
Performance Awards may be expressed in terms of (i) earnings per Share, (ii)
Share price, (iii) pre-tax profits, (iv) net earnings, (v) return on equity or
assets, (vi) revenues, (vii) EBITDA, (viii) market share or market penetration
or (ix) any combination of the foregoing, and may be determined before or after
accounting changes, special charges, foreign currency effects, acquisitions,
divestitures or other extraordinary events. Performance Objectives may be in
respect of the performance of the Company and its Subsidiaries (which may be on
a consolidated basis), a Subsidiary or a Division. Performance Objectives may be
absolute or relative and may be expressed in terms of a progression within a
specified range. The Performance Objectives with respect to a Performance Cycle
shall be established in writing by the Committee by the earlier of (i) the date
on which a quarter of the Performance Cycle has elapsed or (ii) the date which
is ninety (90) days after the commencement of the Performance Cycle, and in any
event, while the performance relating to the Performance Objectives remains
substantially uncertain.

                 (b) Determination of Performance. Prior to the vesting,
payment, settlement or lapsing of any restrictions with respect to any
Performance Award made to a Grantee who is subject to Section 162(m) of the
Code, the Committee shall certify in writing that the applicable Performance
Objectives have been satisfied.


                                      -23-


<PAGE>


            11.2 Performance Units. The Committee, in its sole discretion, may
grant Awards of Performance Units to Eligible Individuals (with the exception of
Non-Employee Directors), the terms and conditions of which shall be set forth in
an Agreement between the Company and the Grantee. Performance Units shall be
denominated in Shares or dollars and, contingent upon the attainment of
specified Performance Objectives within the Performance Cycle, represent the
right to receive payment as provided in Section 11.2(b) depending on the level
of Performance Objective attainment. Each Agreement shall specify the number of
Performance Units to which it relates, the Performance Objectives which must be
satisfied in order for the Performance Units to vest and the Performance Cycle
within which such Performance Objectives must be satisfied.

                 (a) Vesting and Forfeiture. Subject to Sections 11.1(b) and
11.4, a Grantee shall become vested with respect to the Performance Units to the
extent that the Performance Objectives set forth in the Agreement are satisfied
for the Performance Cycle.

                 (b) Payment of Awards. Payment to Grantees in respect of vested
Performance Units shall be made as soon as practicable after the last day of the
Performance Cycle to which such Award relates unless the Agreement evidencing
the Award provides for the deferral of payment, in which event the terms and
conditions of the deferral shall be set forth in the Agreement. Subject to
Section 11.4, such payments may be made entirely in Shares valued at their Fair
Market Value as of the last day of the applicable Performance Cycle or such
other date specified by the Committee, entirely in cash, or in such combination
of Shares and cash as the Committee in its sole discretion shall determine at
any time prior to such payment.

            11.3 Performance Shares. The Committee, in its sole discretion, may
grant Awards of Performance Shares to Eligible Individuals (with the exception
of Non-Employee Directors), the terms and conditions of which shall be set forth
in an Agreement between the Company and the Grantee. Each Agreement may require
that an appropriate legend be placed on Share certificates. Awards of
Performance Shares shall be subject to the following terms and provisions:

                 (a) Rights of Grantee. The Committee shall provide at the time
an Award of Performance Shares is made the time or times at which the actual
Shares represented by such Award shall be issued in the name of the Grantee;
provided, however, that no Performance Shares shall be issued until the Grantee
has executed an Agreement evidencing the Award, the appropriate blank stock
powers and, in the sole discretion of the Committee, an escrow agreement and any
other documents which the Committee may require as a condition to the issuance
of such Performance Shares. If a Grantee shall fail to execute the Agreement
evidencing an Award of Performance Shares, the appropriate blank stock powers
and, in the sole discretion of the Committee, an escrow agreement and any other
documents which the Committee may require within the time period prescribed by
the Committee at the time the Award is granted, the Award shall be null and
void. At the sole discretion of the Committee, Shares issued in connection with
an Award of Performance


                                      -24-

<PAGE>


Shares shall be deposited together with the stock powers with an escrow agent
(which may be the Company) designated by the Committee. Except as restricted by
the terms of the Agreement, upon delivery of the Shares to the escrow agent, the
Grantee shall have, in the sole discretion of the Committee, all of the rights
of a stockholder with respect to such Shares, including the right to vote the
Shares and to receive all dividends or other distributions paid or made with
respect to the Shares.

                 (b) Non-transferability. Until any restrictions upon the
Performance Shares awarded to a Grantee shall have lapsed in the manner set
forth in Sections 11.3(c) or 11.4, such Performance Shares shall not be sold,
transferred or otherwise disposed of and shall not be pledged or otherwise
hypothecated, nor shall they be delivered to the Grantee. The Committee may also
impose such other restrictions and conditions on the Performance Shares, if any,
as it deems appropriate.

                 (c) Lapse of Restrictions. Subject to Sections 11.1(b) and
11.4, restrictions upon Performance Shares awarded hereunder shall lapse and
such Performance Shares shall become vested at such time or times and on such
terms, conditions and satisfaction of Performance Objectives as the Committee
may, in its sole discretion, determine at the time an Award is granted.

                 (d) Treatment of Dividends. At the time the Award of
Performance Shares is granted, the Committee may, in its sole discretion,
determine that the payment to the Grantee of dividends, or a specified portion
thereof, declared or paid on actual Shares represented by such Award which have
been issued by the Company to the Grantee shall be (i) deferred until the
lapsing of the restrictions imposed upon such Performance Shares and (ii) held
by the Company for the account of the Grantee until such time. In the event that
dividends are to be deferred, the Committee shall determine whether such
dividends are to be reinvested in Shares (which shall be held as additional
Performance Shares) or held in cash. If deferred dividends are to be held in
cash, there may be credited at the end of each year (or portion thereof)
interest on the amount of the account at the beginning of the year at a rate per
annum as the Committee, in its sole discretion, may determine. Payment of
deferred dividends in respect of Performance Shares (whether held in cash or in
additional Performance Shares), together with interest accrued thereon, if any,
shall be made upon the lapsing of restrictions imposed on the Performance Shares
in respect of which the deferred dividends were paid, and any dividends deferred
(together with any interest accrued thereon) in respect of any Performance
Shares shall be forfeited upon the forfeiture of such Performance Shares.

                 (e) Delivery of Shares. Upon the lapse of the restrictions on
Performance Shares awarded the Committee shall cause a stock certificate to be
delivered to the Grantee, free of all restrictions hereunder.


                                      -25-

            11.4 Effect of Change in Control. In the event of a Change in
Control:

                 (a) With respect to Performance Units, unless otherwise
determined by the Committee, the Grantee shall (i) become vested in all
Performance Units and (ii) be entitled to receive in respect of all Performance
Units which become vested as a result of a Change in Control a cash payment
within ten (10) Business Days after such Change in Control in an amount as
determined by the Committee at the time of the Award of such Performance Unit
and as set forth in the Agreement.

                 (b) With respect to Performance Shares, unless otherwise
determined by the Committee, restrictions shall lapse immediately on all
Performance Shares.

                 (c) The Agreements evidencing Performance Shares and
Performance Units shall provide for the treatment of such Awards (or portions
thereof) which do not become vested as the result of a Change in Control,
including, without limitation, provisions for the adjustment of applicable
Performance Objectives.

            11.5 Termination. Except as provided in Section 12, and unless
otherwise provided by the Committee, in its sole discretion, in the applicable
Agreement, the following provisions shall apply to Performance Awards upon a
Termination of Employment:

                 (a) Termination of Employment. Except as provided in Sections
11.5(b) and (d), in the case of a Grantee's Termination of Employment, prior to
the end of a Performance Cycle, the Grantee will not be entitled to any
Performance Awards, and any Performance Shares shall be forfeited.

                 (b) Disability, Retirement or Death. Unless otherwise provided
by the Committee, in its sole discretion, in the Agreement, if a Grantee's
Disability Date or Termination of Employment by reason of retirement on or after
the Grantee's Normal Retirement Date or death occurs following at least twelve
months of participation in any Performance Cycle, but prior to the end of a
Performance Cycle, the Grantee or such Grantee's Beneficiary, as the case may
be, shall be entitled to receive a pro-rata share of his or her Performance
Award as determined under Subsection (c).

                 (c) Pro-Rata Payment.

                     (i) Performance Units. With respect to Performance Units,
the amount of any payment made to a Grantee (or Beneficiary) under circumstances
described in Section 11.5(b) will be the amount determined by multiplying the
amount of the Performance Units payable in Shares or dollars which would have
been earned, determined at the end of the Performance Cycle, had such employment
not been terminated, by a fraction, the numerator of which is the number of
whole months such Grantee was employed during the Performance Cycle, and the
denominator of which is the total number of months of the Performance Cycle. Any
such payment shall be made as soon as practicable after the



                                      -26-

<PAGE>


end of the respective Performance Cycle, and shall relate to attainment of
Performance Objectives over the entire Performance Cycle.

                     (ii) Performance Shares. With respect to Performance
Shares, the amount of Performance Shares held by a Grantee (or Beneficiary) with
respect to which restrictions shall lapse under circumstances described in
Section 11.5(b) will be the amount determined by multiplying the amount of the
Performance Shares with respect to which restrictions would have lapsed,
determined at the end of the Performance Cycle, had such employment not been
terminated, by a fraction, the numerator of which is the number of whole months
such Grantee was employed during the Performance Cycle, and the denominator of
which is the total number of months of the Performance Cycle. The Committee
shall determine the amount of Performance Shares with respect to which
restrictions shall lapse under this Section 11.5(c)(ii) as soon as practicable
after the end of the respective Performance Cycle, and such determination shall
relate to attainment of Performance Objectives over the entire Performance
Cycle. At that time, all Performance Shares relating to that Performance Cycle
with respect to which restrictions shall not lapse shall be forfeited.

                 (d) Other Events. Notwithstanding anything to the contrary in
this Section 11, the Committee may, in its sole discretion, determine to pay all
or any portion of a Performance Award to a Grantee who has terminated employment
prior to the end of a Performance Cycle under certain circumstances (including,
without limitation, a material change in circumstances arising after the Date of
Grant) and subject to such terms and conditions that the Grantee shall have
completed, at his or her Termination of Employment at least one year of
employment after the Date of Grant.

            11.6 Modification or Substitution. Subject to the terms of the Plan,
including, without limitation, Section 16(b), the Committee may modify
outstanding Performance Awards or accept the surrender of outstanding
Performance Awards and grant new Performance Awards in substitution for them.
Notwithstanding the foregoing, no modification of a Performance Award shall
adversely alter or impair any rights or obligations under the Agreement without
the Grantee's consent.

        12. Employment Agreement Governs Termination of Employment. An
employment agreement, if applicable, between an Optionee or Grantee and the
Company shall govern with respect to the terms and conditions applicable to such
Option or Award upon a termination or change in the status of the employment of
the Optionee or Grantee, to the extent that such employment agreement provides
for terms and conditions that differ from the terms and conditions provided for
in the applicable Agreement or the Plan; provided, however, that to the extent
necessary for an Option or Award intended to qualify as performance-based
compensation under Section 162(m) of the Code to so qualify, the terms of the
applicable Agreement or the Plan shall govern the Option or Award; and,


                                      -27-


<PAGE>


provided further, that the Committee shall have reviewed and, in its sole
discretion, approved the employment agreement.

        13. Adjustment Upon Changes in Capitalization.

            (a) In the event of a Change in Capitalization, the Committee shall
conclusively determine the appropriate adjustments, if any, to (i) the maximum
number and class of Shares or other stock or securities with respect to which
Options or Awards may be granted under the Plan, (ii) the maximum number and
class of Shares or other stock or securities with respect to which Options or
Awards may be granted to any Eligible Individual during any calendar year, (iii)
the number and class of Shares or other stock or securities which are subject to
outstanding Options or Awards granted under the Plan and the purchase price
therefor, if applicable, (iv) the number and class of Shares or other securities
in respect of which Automatic Options are to be granted under Section 6 and (v)
the Performance Objectives.

            (b) Any such adjustment in the Shares or other stock or securities
subject to outstanding Incentive Stock Options (including any adjustments in the
purchase price) shall be made in such manner as not to constitute a modification
as defined by Section 424(h)(3) of the Code and only to the extent otherwise
permitted by Sections 422 and 424 of the Code.

            (c) If, by reason of a Change in Capitalization, a Grantee of an
Award shall be entitled to, or an Optionee shall be entitled to exercise an
Option with respect to, new, additional or different shares of stock or
securities, such new, additional or different shares shall thereupon be subject
to all of the conditions, restrictions and performance criteria which were
applicable to the Shares subject to the Award or Option, as the case may be,
prior to such Change in Capitalization.

        14. Effect of Certain Transactions. Subject to Sections 7.3, 8.8,
10.4(b) and 11.4 or as otherwise provided in an Agreement, in the event of (i)
the liquidation or dissolution of the Company or (ii) a merger or consolidation
of the Company (a "Transaction"), the Plan and the Options and Awards issued
hereunder shall continue in effect in accordance with their respective terms,
except that following a Transaction each Optionee and Grantee shall be entitled
to receive in respect of each Share subject to any outstanding Options or
Awards, as the case may be, upon exercise of any Option or payment or transfer
in respect of any Award, the same number and kind of stock, securities, cash,
property or other consideration that each holder of a Share was entitled to
receive in the Transaction in respect of a Share; provided, however, that such
stock, securities, cash, property, or other consideration shall remain subject
to all of the conditions, restrictions and performance criteria which were
applicable to the Options and Awards prior to such Transaction.

        15. Limitation on Transfer. Subject to any limitations on
transferability specifically provided for elsewhere in the Plan, the rights and
interest of an Optionee or



                                      -28-

<PAGE>


Grantee in any Option or Award may not be assigned or transferred other than by
will or the laws of descent and distribution or, in the Committee's sole
discretion, pursuant to a domestic relations order (within the meaning of
Exchange Act Rule 16a-12). During the lifetime of an Optionee or Grantee, and
except as the preceding sentence provides, only the Optionee or Grantee
personally may exercise rights under the Plan. Except as otherwise specifically
provided in the Plan, the Beneficiary of an Optionee or Grantee may exercise the
rights of the Optionee or Grantee only to the extent they were exercisable under
the Plan at the date of the death of the Optionee or Grantee and are otherwise
currently exercisable.

        16. Interpretation. Following the required registration of any equity
security of the Company pursuant to Section 12 of the Exchange Act:

            (a) The Plan is intended to comply with Rule 16b-3 promulgated under
the Exchange Act and the Committee shall interpret and administer the provisions
of the Plan or any Agreement in a manner consistent therewith. Any provisions
inconsistent with such Rule shall be inoperative and shall not affect the
validity of the Plan.

            (b) Unless otherwise expressly stated in the relevant Agreement,
each Option, Stock Appreciation Right and Performance Award granted under the
Plan is intended to be performance-based compensation within the meaning of
Section 162(m)(4)(C) of the Code (except that, in the event of a Change in
Control, payment of Performance Awards to a Grantee who remains a "covered
employee" with respect to such payment within the meaning of Section 162(m)(3)
of the Code may not qualify as performance-based compensation). The Committee
shall not be entitled to exercise any discretion otherwise authorized hereunder
with respect to such Options or Awards if the ability to exercise such
discretion or the exercise of such discretion itself would cause the
compensation attributable to such Options or Awards to fail to qualify as
performance-based compensation. Notwithstanding anything to the contrary in the
Plan, the provisions of the Plan may at any time be bifurcated by the Board or
the Committee in any manner so that certain provisions of the Plan or any
Performance Award intended (or required in order) to satisfy the applicable
requirements of Section 162(m) of the Code are only applicable to persons whose
compensation is subject to Section 162(m).

            (c) UK Approved Options are intended to comply with Schedule 9 to
the Taxes Act, and in particular, but without limitation, with paragraphs 10 to
14 thereof, and the Plan shall, except where inconsistent with the subject or
context, be interpreted accordingly.

        17. Pooling Transactions. Notwithstanding anything contained in the Plan
or any Agreement to the contrary, in the event of a Change in Control which is
also intended to constitute a Pooling Transaction, the Committee shall take such
actions, if any, as are specifically recommended by an independent accounting
firm retained by the Company to the extent reasonably necessary in order to
assure that the Pooling Transaction will qualify as such, including, without
limitation, (i) deferring the vesting, exercise, payment, settlement or lapsing
of restrictions with respect to any Option or Award, (ii) providing that the
payment or



                                      -29-

settlement in respect of any Option or Award be made in the form of cash, Shares
or securities of a successor or acquirer of the Company, or a combination of the
foregoing, and (iii) providing for the extension of the term of any Option or
Award to the extent necessary to accommodate the foregoing, but not beyond the
maximum term permitted for any Option or Award.

        18. Effective Date, Termination and Amendment of the Plan. The effective
date of this Plan shall be the date the Plan is adopted by the Board, subject
only to the approval by the affirmative vote of the holders of a majority of the
securities of the Company present, or represented, and entitled to vote at a
meeting of stockholders duly held in accordance with the applicable laws of the
State of Delaware within twelve (12) months of the adoption of the Plan by the
Board.

        The Plan shall terminate on the day preceding the tenth anniversary of
the date of its adoption by the Board and no Option or Award may be granted
thereafter. The Board may sooner terminate the Plan and the Board may at any
time and from time to time amend, modify or suspend the Plan; provided, however,
that: (a) no such amendment, modification, suspension or termination shall
impair or adversely alter any Options or Awards theretofore granted under the
Plan, except with the consent of the Optionee or Grantee, nor shall any
amendment, modification, suspension or termination deprive any Optionee or
Grantee of any Shares which he or she may have acquired through or as a result
of the Plan; and (b) to the extent necessary under applicable law, no amendment
shall be effective unless approved by the stockholders of the Company in
accordance with applicable law.

        No alteration shall be made to provisions of the Plan relating to UK
Approved Options without the prior written approval of the UK Inland Revenue.

        19. Non-Exclusivity of the Plan. The adoption of the Plan by the Board
shall not be construed as amending, modifying or rescinding any previously
approved incentive arrangement or as creating any limitations on the power of
the Board to adopt such other incentive arrangements as it may deem desirable,
including, without limitation, the granting of stock options otherwise than
under the Plan, and such arrangements may be either applicable generally or only
in specific cases.

        20. Limitation of Liability. As illustrative of the limitations of
liability of the Company, but not intended to be exhaustive thereof, nothing in
the Plan shall be construed to:

            (i) give any person any right to be granted an Option or Award other
than at the sole discretion of the Committee;

            (ii) give any person any rights whatsoever with respect to Shares
except as specifically provided in the Plan;


                                      -30-


<PAGE>


            (iii) limit in any way the right of the Company to terminate the
employment of any person at any time; or

            (iv) be evidence of any agreement or understanding, expressed or
implied, that the Company will employ any person at any particular rate of
compensation or for any particular period of time.

        21. Regulations and Other Approvals; Governing Law.

            21.1 Except as to matters of federal law, the Plan and the rights of
all persons claiming hereunder shall be construed and determined in accordance
with the laws of the State of Delaware without giving effect to conflicts of
laws principles thereof.

            21.2 The obligation of the Company to sell or deliver Shares with
respect to Options and Awards granted under the Plan shall be subject to all
applicable laws, rules and regulations, including all applicable federal and
state securities laws, and the obtaining of all such approvals by governmental
agencies as may be deemed necessary or appropriate by the Committee.

            21.3 The Board may make such changes as may be necessary or
appropriate to comply with the rules and regulations of any government
authority, or to obtain for Eligible Individuals granted Incentive Stock Options
the tax benefits under the applicable provisions of the Code and regulations
promulgated thereunder.

        The Board may make such changes as may be necessary or appropriate to
obtain or maintain the approval of the provisions of the Plan relating to UK
Approved Options by the UK Inland Revenue.

            21.4 Each Option and Award is subject to the requirement that, if at
any time the Committee determines, in its sole discretion, that the listing,
registration or qualification of Shares issuable pursuant to the Plan is
required by 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 grant of an Option or
Award or the issuance of Shares, no Options or Awards shall be granted or
payment made or Shares issued, in whole or in part, unless listing,
registration, qualification, consent or approval has been effected or obtained
free of any conditions as acceptable to the Committee.

            21.5 Notwithstanding anything contained in the Plan or any Agreement
to the contrary, in the event that the disposition of Shares acquired pursuant
to the Plan is not covered by a then current registration statement under the
Securities Act of 1933, as amended (the "Securities Act"), and is not otherwise
exempt from such registration, such Shares shall be restricted against transfer
to the extent required by the Securities Act and Rule 144 or other regulations
thereunder. The Committee may require any individual receiving Shares pursuant
to an Option or Award granted under the Plan, as a condition precedent to
receipt of such Shares, to represent and warrant to the Company in writing that
the Shares acquired by


                                      -31-


<PAGE>


such individual are acquired without a view to any distribution thereof and will
not be sold or transferred other than pursuant to an effective registration
thereof under said Act or pursuant to an exemption applicable under the
Securities Act or the rules and regulations promulgated thereunder. The
certificates evidencing any of such Shares shall be appropriately amended to
reflect their status as restricted securities as aforesaid.

        22. Miscellaneous.

            22.1 Multiple Agreements. The terms of each Option or Award may
differ from other Options or Awards granted under the Plan at the same time, or
at some other time. The Committee may also grant more than one Option or Award
to a given Eligible Individual during the term of the Plan, either in addition
to, or in substitution for, one or more Options or Awards previously granted to
that Eligible Individual.

            22.2 Withholding of Taxes.

                 (a) At such times as an Optionee or Grantee recognizes taxable
income in connection with the receipt of Shares or cash hereunder (a "Taxable
Event"), the Optionee or Grantee shall pay to the Company an amount equal to the
federal, state and local income taxes and other amounts as may be required by
law to be withheld by the Company in connection with the Taxable Event (the
"Withholding Taxes") prior to the issuance, or release from escrow, of such
Shares or the payment of such cash. The Company shall have the right to deduct
from any payment of cash to an Optionee or Grantee an amount equal to the
Withholding Taxes in satisfaction of the obligation to pay Withholding Taxes. In
satisfaction of the obligation to pay Withholding Taxes to the Company, the
Optionee or Grantee may make a written election (the "Tax Election"), which may
be accepted or rejected in the sole discretion of the Committee, to have
withheld a portion of the Shares then issuable to him or her having an aggregate
Fair Market Value equal to the Withholding Taxes.

                 (b) If an Optionee makes a disposition, within the meaning of
Section 424(c) of the Code and regulations promulgated thereunder, of any Share
or Shares issued to such Optionee pursuant to the exercise of an Incentive Stock
Option within the two-year period commencing on the day after the date of the
grant or within the one-year period commencing on the day after the date of
transfer of such Share or Shares to the Optionee pursuant to such exercise, the
Optionee shall, within ten (10) Business Days of such disposition, notify the
Company thereof, by delivery of written notice to the Company at its principal
executive office.

        22.3 Power of Attorney given by UK Employees. The following provisions
shall apply only to Options and Awards granted to UK-resident or ordinarily
resident Employees.

             (a) It shall be a condition of all Options (which term shall for
the purposes of paragraphs 22.3 (a) through (d) exclude UK Approved Options
which retain approval from the UK Inland Revenue under Schedule 9 to the Taxes
Act) and Awards



                                      -32-

<PAGE>


granted to UK Employees and a condition precedent to the vesting,
exercisability, or release for consideration, of all such Options and Awards
that, if the vesting, exercise, or release for consideration gives rise to a
liability of the Company or any Subsidiary (the "Relevant Body") under Section
203F of the Taxes Act or otherwise pursuant to the United Kingdom's Pay As You
Earn ("PAYE") system (or any other similar withholding tax system in any other
applicable jurisdiction), the Relevant Body shall (to the extent permitted by
English law) be entitled to withhold from such Grantee's or Optionee's salary or
other payments due to him, and/or the Grantee or Optionee shall be required to
pay to the Relevant Body, as a condition of such vesting, exercise or release,
the amount which the Relevant Body is required to pay to the UK Inland Revenue
(or other relevant taxing authority).

             (b) Any payment by the Grantee or Optionee shall be made within
such period as the Relevant Body shall notify to him. The Company may refuse to
permit (a) the vesting or exercise of any Option or Award or (b) the release of
any Option or Award for consideration if any such payment is not satisfied by
the Grantee or Optionee within such period as shall have been notified to him.

             (c) Alternatively, if the Committee so decides in its absolute
discretion, the PAYE or other taxation liability falling upon any Relevant Body
may be satisfied by (a) the Company not releasing to the Grantee or Optionee
concerned such number of Shares (which expression shall for this purpose include
other shares or securities to be issued upon such vesting or exercise) or (b)
deducting from any consideration for the release of an Option or Award such
monetary amount as shall in either case equal in value the amount required to be
paid to the Inland Revenue (or other relevant taxing authority), together (where
relevant) with any commission or similar costs associated with or to be incurred
upon the disposal of any such Shares to fund such tax liability.

             (d) Each holder of an Option or an Award under the Plan hereby
appoints any Director of the Company or a Subsidiary as his attorney for the
purpose of signing, in the name and on behalf of such holder, any documents
required to implement the foregoing (including, without prejudice to the
generality of the foregoing, the right to sell Shares not so released as
aforesaid).
