4.   ELIGIBILITY AND PARTICIPATION
     -----------------------------

     Executives eligible for bonuses under the Plan shall be those individuals
     specified in Appendix I.

5.   BONUS FUNDING MECHANISM
     -----------------------

     5.1  The on-target bonus Fund will be determined as follows:

          (a)  Each Participant will be eligible to receive up to 60% of
               on-target funded bonus if the Company achieves quarterly and
               annual Plan Revenues and Net Income as stated in Appendix II.

          (b)  The percentage of the on-target bonus described in Appendix I
               earned by each Participant on achievement of the amounts stated
               in Appendix II in respect of each quarter and year end is:

               (i)   Q1        5% based on revenue,  5% based on earnings

               (ii)  Q2        5% based on revenue,  5% based on earnings

               (iii) Q3        5% based on revenue,  5% based on earnings

               (iv)  Q4        5% based on revenue,  5% based on earnings

               (v)   Year end 10% based on revenue, 10% based on earnings

<PAGE>   4

          (c)  In the event that the achievement in any quarter or for the year
               is less than the amounts stated in Appendix II, but is equal to
               or greater than 90% of the amount in question, then a partial
               bonus shall be paid to each participant. The partial bonus shall
               be equal to the actual achievement divided by the amount stated
               in Appendix II times the on-target bonus the participant would
               otherwise have earned.

          (d)  In the event that the achievement in any quarter or for the year
               is greater than the amounts stated in Appendix II, than an
               incremental bonus shall be paid to each participant. The
               incremental bonus shall be equal to the actual achievement
               divided by the amount stated in Appendix II times the on-target
               bonus the participant would otherwise have earned, except that
               the incremental bonus in each instance shall not be greater than
               110% of the on-target bonus the participant would have received
               in respect of the individual quarterly or annual earnings or
               revenue based component.

          (e)  20% of the on-target bonus described in Appendix I earned by each
               participant shall be based on share price appreciation. The
               calculation for this portion of the year end bonus shall be as
               follows: an amount equal to .20% of the on-target year end bonus
               shall be earned by each participant for each 1% increase in the
               share price over the term of fiscal 2000, adjusted for any future
               stock splits, over $26.75 (the share price as of the close on the
               last day of the previous fiscal year adjusted for the stock split
               in December, 1999). By way of example, if the share price closes
               at $53.50 on September 30, 2000, (a 100% increase) each
               participant would earn 100 times .20 or 20% of the specified
               on-target bonus as set forth in Appendix I on account of share
               price appreciation. In no event shall the amount earned by each
               participant on account of share price appreciation be greater
               than 20% of on-target bonus. In the event an individual is not
               employed at the beginning of a fiscal year, their first day of
               employment shall be used as the starting share price for the
               purpose of calculating share price appreciation during the
               balance of the fiscal year and the maximum 20% of on-target award
               shall be prorated to an amount proportional to the number of days
               remaining in the fiscal year.

          (f)  20% of the on-target year end bonus shall be at the discretion of
               the Compensation Committee in the case of the Chairman and the
               CEO and in the case of the participants in Appendix I, Section
               II, based upon an evaluation of the individual goals agreed to
               between the CEO and the participant as evaluated by the CEO and
               the Chairman.

6.   PAYMENT OF BONUSES
     ------------------

     Funded bonus will be payable not later than sixty days after the end of the
     period in which the bonus was earned provided that the results for the
     period have been issued to the public.

7.   TERMINATION OF EMPLOYEE
     -----------------------

     7.1  If a Participant's employment is terminated prior to the conclusion of
          any Plan Quarter or, following the conclusion of a Plan Year, or prior
          to any payment being made:

          (a)  By reason of (i) any deliberate material breach by the
               Participant of his employment obligations with the Company,
               which, if curable, is not cured within ten (10) days after the
               Company shall have notified the Participant in writing describing
               to Participant all material facts concerning such breach, (ii)
               any deliberate material breach by the Participant of his
               employment obligations with the Company, which is not curable
               according to notice from the Company, or (iii) the conviction of
               a felony or the commission of a material, fraudulent act by the
               Participant against the Company;

          (b)  Voluntarily by Participant other than for a "Reason Constituting
               Good Cause." Reasons Constituting Good Cause are limited to: (i)
               a significant change in the nature and scope of Participant's
               duties combined with a change in the Participant's title
               resulting in a position of materially lesser authority, or (ii) a
               reduction in the Participant's base compensation.

          Then, Participant shall cease to have any rights to any amounts unpaid
          on the date of termination of employment.

     7.2  If a Participant's employment is terminated:

          (a)  By reason of Death, Permanent Disability; or

          (b)  By the Company for a reason other than one described at
               subparagraph 7.1(a);

          If such a termination occurs prior to the conclusion of any Plan
          Quarter or Year, the Participant shall receive the amount which the
          Participant otherwise would have been entitled to receive had he
          remained in the employ of the Company through the end of the Plan
          Year, but pro-rated based on the number of complete months of
          employment with the Company during such Plan Year. The amount earned
          shall be paid according to the Plan rules.

8.   BENEFICIARY DESIGNATIONS
     ------------------------

<PAGE>   6

     8.1  If a Participant's employment with the Company is terminated by his
          death or if he dies after termination of his employment but prior to
          the distribution to him of all amounts payable to him under the Plan,
          any amounts otherwise payable to him hereunder shall be distributed to
          his designated beneficiary or beneficiaries. For the purposes of this
          plan a Participant's beneficiary will be the beneficiary designated
          under Company provided life insurance coverage. However, a Participant
          may from time to time revoke or change any beneficiary designation on
          file with the Company.

          If there is no effective beneficiary designation on file with the
          Company at the time of a Participant's death, distribution of amounts
          otherwise payable to the deceased Participant under this Plan shall be
          made to the Participant's estate. If a beneficiary designated by the
          Participant to receive his benefits shall survive the Participant but
          die before receiving all distributions hereunder, the balance thereof
          shall be paid to such deceased beneficiary's estate, unless the
          deceased beneficiary designation provides otherwise.

     8.2  The Company shall deduct from the distributions to be made to a
          Participant or his designated beneficiary or beneficiaries under this
          Plan any federal, state or local withholding or other taxes or charges
          which the Company is from time to time required to deduct under
          applicable law and all amounts distributable under this Plan are
          stated herein before any such deductions. The Company may rely on a
          written opinion from its legal counsel regarding any questions which
          may arise in connection with any such deductions.

9.   RIGHTS, PRIVILEGES AND DUTIES OF PARTICIPATION
     ----------------------------------------------

     9.1  No participant or other person shall have any interest in any fund or
          in any specific asset or assets of the Company and its Subsidiaries by
          reason of being a Participant under this Plan nor any right to receive
          any distributions under the Plan except as and to the extent expressly
          provided in the Plan.

     9.2  The Company shall have the right, but shall be under no obligation, to
          segregate cash to fund bonuses payable under the Plan. However, any
          such segregated amounts shall at all times remain Company assets,
          subject to the claims of its creditors.

     9.3  Each Participant shall be entitled to receive a current copy of the
          Plan upon his designation as a Participant if a written request for a
          copy of the Plan is provided to the Chief Executive Officer or the
          Chairman of the Board. Thereafter, as long as he remains a
          Participant, he shall be entitled to receive copies of any amendments
          to the Plan within sixty (60) days after their adoption.

     9.4  The designation of any employee as a Participant under this Plan shall
          not be construed as conferring upon such employee any right to remain
          in the employ of the Company and each such Participant shall remain an
          employee at will. The right of

<PAGE>   7

          the Company to discipline or discharge an employee shall not be
          affected in any manner by reason of such employee's designation as a
          Participant under this Plan.

     9.5  To the extent permitted by law, the right of any Participant or any
          beneficiary to receive any payment hereunder shall not be subject to
          alienation, transfer, sale, assignment, pledge, attachment,
          garnishment or encumbrance of any kind. Any attempt to alienate,
          transfer, sell, assign, pledge or otherwise encumber any such payment
          whether presently or thereafter payable, shall be void. Any payment
          due hereunder shall not in any manner be subject to any debts or
          liabilities of any Participant or his beneficiary.

Bonuses or rights to purchase restricted stock granted pursuant to Section 8
hereof, (iii) Stock Appreciation Rights granted pursuant to Section 9 hereof or

3.  ADMINISTRATION

     (a) Administration of the Plan shall be delegated to a committee composed

Committee shall be Non-Employee Directors and Outside Directors. The Committee
shall have, in connection with the administration of the Plan, the powers set
forth in the Plan, subject, however, to such resolutions, not inconsistent with
the provisions of the Plan, as may be adopted from time to time by the Board.
The Board may abolish the Committee at any time and revisit in the Board the
administration of the Plan. The Board shall have the authority to correct any
defect, omission or inconsistency in the Plan and to amend the Plan as provided
in Section 16. The Board shall have the authority to appoint the Committee and
to fill any vacancy created on the Committee by reason of the death, resignation
or removal of any member thereof by appointing an eligible successor.
Notwithstanding anything in this Section 3 to the contrary, at any time the
Board or the Committee may delegate to a committee of one or more members of the
Board the authority to grant Stock Awards to eligible persons who are not then
subject to Section 16 of the Exchange Act and to eligible persons with respect
to whom the Company does not wish to comply with Section 162(m) of the Code.

     (b) The Committee shall have the power, subject to, and within the
limitations of, the express provisions of the Plan:

          (i) To determine from time to time which of the persons eligible under
     the Plan shall be granted Stock Awards; when and how Stock Awards shall be
     granted; whether a Stock Award will be an Incentive Stock Option, a
     Nonstatutory Stock Option, a Stock Bonus, a right to purchase restricted
     stock, a Stock Appreciation Right, another stock-based award or a
     combination of the foregoing; the provisions

                                       4
<PAGE>   5

     of each Stock Award granted (which need not be identical), including the
     time or times when a person shall be permitted to receive stock pursuant to
     a Stock Award; whether a person shall be permitted to receive stock upon
     exercise of an Independent Stock Appreciation Right; and the number of
     shares with respect to which Stock Awards shall be granted to each such
     person.

          (ii) To construe and interpret the Plan and Stock Awards granted under
     it, and to establish, amend and revoke rules and regulations for its
     administration. The Committee, in the exercise of this power, may correct
     any defect, omission or inconsistency in any Stock Award Agreement, in a
     manner and to the extent it shall deem necessary or expedient to make the
     Stock Award Agreement fully effective.

          (iii) To amend any Stock Award.

          (iv) Generally, to exercise such powers and to perform such acts as
     the Committee deems necessary or expedient to promote the best interests of
     the Company and which are not in conflict with the provisions of the Plan.

4.  SHARES SUBJECT TO THE PLAN.

     (a) Subject to the provisions of Section 15 hereof relating to adjustments
upon Changes in Stock, the number of shares of stock that may be issued pursuant
to Stock Awards under the Plan shall be equal to 1,850,000 shares of Company
Common Stock (which reflects the stock split effected by means of a stock
dividend on December 15, 1999). If any Stock Award shall for any reason expire
or otherwise terminate without having been exercised in full, the Company Common
Stock not purchased shall again become available for issuance under the Plan.
Notwithstanding the foregoing, shares of Company Common Stock subject to Stock
Appreciation Rights exercised in accordance with Section 8 hereof shall not be
available for subsequent issuance under the Plan.

     (b) The Company Common Stock subject to the Plan may consist in whole or in
part of authorized but unissued shares or treasury shares. Subject to Section
4(a) hereof, no more than two hundred thousand (200,000) shares of Company
Common Stock may be subject to Stock Bonus or restricted stock purchase.

5.  ELIGIBILITY.

     (a) Incentive Stock Options and Stock Appreciation Rights appurtenant
thereto may be granted only to Employees. Other Stock Awards may be granted to
Employees, Directors or Consultants, provided, however, that Stock Awards may be
granted to Non-Employee Directors only as provided in Section 7(a).

     (b) No person shall be eligible for the grant of an Incentive Stock Option
if, at the time of grant, such person owns (or is deemed to own pursuant to
Section 424(d) of the Code) Company Common Stock possessing more than ten
percent (10%) of the total combined voting power of all classes of capital stock
of the Company or of any of its Affiliates unless the exercise price of such
Incentive Stock Option is at least one hundred ten percent (110%) of the Fair
Market Value of such Company Common Stock at the date of grant and the Incentive
Stock Option is not exercisable after the expiration of five (5) years from the
date of grant.

     (c) No person shall be eligible to be granted Stock Awards covering more
than two hundred thousand (200,000) shares of Company Common Stock in any Plan
Year.

6.  OPTION PROVISIONS.

     Each Option Agreement shall be in such form and shall contain such terms
and conditions as the Committee shall deem appropriate. The provisions of
separate Option Agreements need not be identical, but each Option Agreement
shall include (through incorporation of provisions hereof by reference in the
Option Agreement or otherwise) the substance of each of the following provisions
except as otherwise specifically provided elsewhere in the Plan:

          (a) Term.  No Option shall be exercisable after the expiration of ten
     (10) years from the date it was granted.

                                       5
<PAGE>   6

          (b) Price.  Subject to subsection 5(b) hereof, the exercise price of
     each Incentive Stock Option shall be not less than one hundred percent
     (100%) of the Fair Market Value of the Company Common Stock subject to the
     Option on the date the Option is granted. The exercise price of each
     Nonstatutory Stock Option shall be set by the Committee at the time each
     Option is granted.

          (c) Consideration.  The purchase price of stock acquired pursuant to
     an Option shall be paid, to the extent permitted by applicable statutes and
     regulations, either: (i) in cash at the time the Option is exercised, or
     (ii) at the discretion of the Committee, either at the time of the grant or
     exercise of the Option, (A) by delivery to the Company of other Common
     Stock of the Company owned by the Optionee for a period of at least six
     months, (B) according to a deferred payment or other arrangement (which may
     include, without limiting the generality of the foregoing, the use of other
     Common Stock of the Company) with the person to whom the Option is granted
     or to whom the Option is transferred pursuant to subsection 6(d) hereof, or
     (C) in any other form of legal consideration that may be acceptable to the
     Committee on terms determined by the Committee.

          In the case of any deferred payment arrangement, interest shall be
     payable at least annually and shall be charged at the minimum rate of
     interest necessary to avoid the treatment as interest, under any applicable
     provisions of the Code, of any amounts other than amounts stated to be
     interest under the deferred payment arrangement.

          (d) Transferability.  An Incentive Stock Option shall not be
     transferable except by will or by the laws of descent and distribution, and
     shall be exercisable during the lifetime of the person to whom the
     Incentive Stock Option is granted only by such person. A Nonstatutory Stock
     Option may be transferable to the extent specified in the Option Agreement,
     in which case the Option may be transferred upon such terms and conditions
     as are set forth in the Option Agreement, as the Committee shall determine
     in its sole discretion, including (without limitation) pursuant to a
     "domestic relations order" within the meaning of such rules, regulations or
     interpretation of the Securities and Exchange Commission as are applicable
     for purposes of Section 16 of the Exchange Act, or to family members, or to
     trusts or other entities maintained for the benefit of family members.
     Notwithstanding the foregoing, the person to whom an Option is granted may,
     by delivering written notice to the Company, in a form satisfactory to the
     Company, designate a third party who, in the event of the death of the
     Optionee, shall thereafter be entitled to exercise the Option.

          (e) Vesting.  The total number of shares of stock subject to an Option
     may, but need not, be allotted in periodic installments (which may, but
     need not, be equal). The Option Agreement may provide that from time to
     time during each of such installment periods, the Option may become
     exercisable ("vest") with respect to some or all of the shares allotted to
     that period, and may be exercised with respect to some or all of the shares
     allotted to such period and/or any prior period as to which the Option
     became vested but was not fully exercised. The Option may be subject to
     such other terms and conditions on the time or times when it may be
     exercised (which may be based on performance or other criteria) as the
     Committee may deem appropriate. During the remainder of the term of the
     Option (if its term extends beyond the end of the installment periods), the
     Option may be exercised from time to time with respect to any shares then
     remaining subject to the Option. The provisions of this subsection 6(e) are
     subject to any Option provisions governing the minimum number of shares as
     to which an Option may be exercised.

          (f) Termination of Employment or Relationship as A Consultant.  In the
     event an Optionee's Continuous Status as an Employee or Consultant
     terminates (other than upon the Optionee's death or Disability), the
     Optionee may exercise his or her Option, but only within such period of
     time ending on the earlier of (i) the date three (3) months after
     termination of the Optionee's Continuous Status as an Employee or
     Consultant (or such longer (but only in the case of a Nonstatutory Stock
     Option) or shorter period of time specified in the Option Agreement), or
     (ii) the expiration of the Option's term, and only to the extent that the
     Optionee was entitled to exercise it at the date of termination (but in no
     event later than the expiration of the term of such Option as set forth in
     the Option Agreement). If, at the date of termination, the Optionee is not
     entitled to exercise his or her entire Option, the shares covered by the
     unexercisable portion of the Option shall revert to and again become
     available for issuance under the

                                       6
<PAGE>   7

     Plan. If, after termination, the Optionee does not exercise his or her
     Option within the time specified in the Option Agreement, the Option shall
     terminate, and the shares covered by such Option shall revert to and again
     become available for issuance under the Plan.

          (g) Disability of Optionee.  In the event an Optionee's Continuous
     Status as an Employee or Consultant terminates as a result of the
     Optionee's Disability, the Optionee may exercise his or her Option, but
     only within such period of time ending on the earlier of (i) the date
     twelve (12) months following such termination (or such longer or shorter
     period of time as specified in the Option Agreement), or (ii) the
     expiration of the term of the Option as set forth in the Option Agreement).
     If, at the date of termination, the Optionee is not entitled to exercise
     his or her entire Option, the shares covered by the unexercisable portion
     of the Option shall revert to the Plan. If, after termination, the Optionee
     does not exercise his or her Option within the time specified herein, the
     Option shall terminate, and the shares covered by such Option shall revert
     to and again become available for issuance under the Plan.

          (h) Death of Optionee.  In the event of the death of an Optionee
     during, or within a period specified in the Option Agreement after the
     termination of, the Optionee's Continuous Status as an Employee or
     Consultant, the Option may be exercised by the Optionee's estate, by a
     person who acquired the right to exercise the Option by bequest or
     inheritance, or by a person designated to exercise the Option upon the
     Optionee's death pursuant to subsection 6(d) hereof, but only within the
     period ending on the earlier of (i) the date twelve (12) months following
     the date of death (or such longer or shorter period specified in the Option
     Agreement) or (ii) the expiration of the term of such Option as set forth
     in the Option Agreement. If, at the time of death, the Optionee was not
     entitled to exercise his or her entire Option, the shares covered by the
     unexercisable portion of the Option shall revert to and again become
     available under the Plan. If, after death, the Option is not exercised
     within the time specified herein, the Option shall terminate, and the
     shares covered by such Option shall revert to and again become available
     for issuance under the Plan.

          (i) Early Exercise.  The Option Agreement may, but need not, include a
     provision whereby the Optionee may elect at any time while an Employee,
     Director or Consultant to exercise the Option as to any part or all of the
     shares subject to the Option prior to the full vesting of the Option. If
     such a provision is included in an Option Agreement, the Option Agreement
     shall also contain provisions establishing a vesting schedule for the
     purchased shares and a right of the Company to repurchase any unvested
     shares or, as a condition to the exercise of the relevant Option, requiring
     the Optionee to enter into an agreement with the Company establishing such
     vesting and such rights.

          (j) Withholding.  To the extent provided by the terms of an Option
     Agreement, the Optionee may satisfy any required minimum federal, state or
     local tax withholding obligation relating to the exercise of such Option by
     any of the following means or by a combination of such means: (1) tendering
     a cash payment; (2) authorizing the Company to withhold shares from the
     shares of the Common Stock otherwise issuable to the participant as a
     result of the exercise of the Option; or (3) delivering to the Company
     owned and unencumbered shares of the Common Stock of the Company.

          (k) Re-Load Options.  Without in any way limiting the authority of the
     Committee to make or not to make grants of Options hereunder, the Committee
     shall have the authority (but not an obligation) to include as part of any
     Option Agreement a provision entitling the Optionee to a further Option (a
     "Re-Load Option") in the event the Optionee exercises the Option evidenced
     by the Option Agreement, in whole or in part, by surrendering other shares
     of Company Common Stock in accordance with the Plan and the terms and
     conditions of the Option Agreement. Any such Re-Load Option (i) shall be
     for a number of shares equal to the number of shares surrendered as part or
     all of the exercise price of such Option, (ii) shall have an expiration
     date which is the same as the expiration date of the Option the exercise of
     which gave rise to such Re-Load Option; and (iii) shall have an exercise
     price which is equal to one hundred percent (100%) of the Fair Market Value
     of the Company Common Stock subject to the Re-Load Option on the date of
     exercise of the original Option or, in the case of a Re-Load Option which
     is an Incentive Stock Option and which is granted to a 10% stockholder (as
     described in subsection 5(c) hereof), shall have an exercise price which is
     equal to one hundred ten percent (110%) of the Fair

                                       7
<PAGE>   8

     Market Value of the Company Common Stock subject to the Re-Load Option on
     the date of exercise of the original Option and shall have a term which is
     no longer than five (5) years.

     Any such Re-Load Option may be an Incentive Stock Option or a Nonstatutory
Stock Option, as the Committee may designate at the time of the grant of the
original Option, provided, however, that the designation of any Re-Load Option
as an Incentive Stock Option shall be subject to the one hundred thousand dollar
($100,000) annual limitation on exercisability of Incentive Stock Options
described in subsection 13(d) hereof and in Section 422(d) of the Code. There
shall be no Re-Load Options on a Re-Load Option. Any such Re-Load Option shall
be subject to the availability of sufficient shares under subsection 4(a) hereof
and shall be subject to such other terms and conditions as the Committee may
determine which are not inconsistent with the express provisions of the Plan
regarding the terms of the Options.

7.  OPTION GRANTS TO NON-EMPLOYEE DIRECTORS.

     (a) Each Non-Employee Director elected or appointed to the Board at the
time of an annual meeting of stockholders or special meeting in lieu thereof,
including Non-Employee Directors elected to the Board at the meeting of the
Company's stockholders at which this amended and restated Plan is approved (the
"Approval Meeting"), upon first being so elected or appointed, shall
automatically be granted a Nonstatutory Stock Option to purchase 27,000 shares
of Company Common Stock.

     (b) Notwithstanding the preceding section 7(a), in the event that a
Non-Employee Director is first elected or appointed to the Board at any time
other than at an annual meeting of stockholders or special meeting in lieu
thereof, such Non-Employee Director upon first being so elected or appointed
shall automatically be granted a Nonstatutory Stock Option for a number of
shares of Company Common Stock equal to the sum of (i) 18,000 plus (ii) 9,000
multiplied by N/365 where "N" is the number of days remaining between the date
of such election or appointment of such Non-Employee Director and the first
anniversary of the date of the Company's most recent annual meeting of
stockholders or special meeting in lieu thereof. The shares purchasable pursuant
to Section 7(b)(ii) above are referred to as the "Prorated Shares". Each option
granted under Section 7(a) or Section 7(b) is referred to herein as an "Initial
Option".

     (c) Each Non-Employee Director shall be eligible to receive an additional
Nonstatutory Stock Option to purchase 27,000 shares of Company Common Stock
(each an "Additional Option") as follows: (i) each Class II and Class III
Non-Employee Director in office on the date of the Approval Meeting shall
automatically be granted an Additional Option and (ii) upon the Final Vesting
Date, as defined below, of any Initial Option or Additional Option held by a
Non-Employee Director whose term in office will continue after such Final
Vesting Date, or who has been nominated by the Board of Directors for election
to a term that will continue after such date, such Non-Employee Director shall
automatically be granted an Additional Option.

     (d) Each Initial Option and each Additional Option shall have an exercise
price equal to the Fair Market Value of the Common Stock on the date of grant.
All Options granted under this Section 7 shall vest in three equal installments
immediately before each of the first three annual meetings of stockholders or
special meetings in lieu thereof following the date of grant of such Initial
Option or Additional Option, as the case may be, provided in each case that at
such time the Non-Employee Director is then in office as a director.
Notwithstanding the preceding sentence, with respect to an Initial Option
granted under Section 7(b) the option shall vest as to the Prorated Shares
immediately before the first annual meeting of stockholders or special meeting
in lieu thereof following the date of grant of such Initial Option and as to the
remaining 18,000 shares in two equal installments immediately before each of the
second and third annual meetings of stockholders or special meetings in lieu
thereof following the date of grant of such Initial Option, provided that in
each case at such time the Non-Employee Director is then in office as a
director. The date on which the last such installment of any option granted
under this Section 7 vests is herein referred to as its "Final Vesting Date."
All options granted under this Section 7 shall expire on the date which is five
years from the date of grant.

     (e) The Committee shall adopt such provisions, in its sole discretion, as
to the time, any limitations or restrictions and the manner of the exercise or
vesting of Nonstatutory Stock Options granted under this Section 7 in respect of
the matters set forth under the provisions of Subsections 6(d), (j) and (k)
hereof.

8.  TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

     Each Stock Bonus or restricted stock purchase agreement related to a Stock
Award shall be in such form and shall contain such terms and conditions as the
Committee shall deem appropriate. The terms and conditions of Stock Bonus or
restricted stock purchase agreements may change from time to time, and the terms
and conditions of separate agreements need not be identical, but each Stock
Bonus or restricted stock purchase agreement shall include (through
incorporation of provisions herein by reference in the agreement or otherwise)
the substance of each of the following provisions as appropriate:

          (a)  Purchase Price.  The purchase price under each restricted stock
     purchase agreement shall be such amount as the Committee shall determine
     and designate in such agreement. Notwithstanding the foregoing, the
     Committee may determine that eligible participants in the Plan may be
     granted a Stock Award pursuant to a Stock Bonus agreement in consideration
     for past services actually rendered to the Company for its benefit.

          (b)  Transferability.  Except as otherwise provided elsewhere in the
     Plan, no rights under a Stock Bonus or restricted stock purchase agreement
     shall be assignable by any participant under the Plan, either voluntarily
     or by operation of law, except by will or by the laws of descent and
     distribution, and shall be exercisable during the lifetime of the person to
     whom the rights are granted only by such person. The person to whom the
     Stock Award is granted, may, by delivering written notice to the Company,
     in a form satisfactory to the Company, designate a third party who, in the
     event of the death of such person, shall thereafter be entitled to exercise
     the rights held by such person under the Stock Bonus or restricted stock
     purchase agreement.

          (c)  Consideration.  The purchase price of stock acquired pursuant to
     a Stock Award in the form of a stock purchase agreement shall be paid
     either: (i) in cash at the time of purchase; (ii) at the discretion of the
     Committee, according to a deferred payment or other arrangement with the
     person to whom the stock is sold; or (iii) in any other form of legal
     consideration that may be acceptable to the Committee in its discretion;
     including delivery of a promissory note of the Optionee to the Company on
     terms determined by the Committee. Notwithstanding the foregoing, the
     Committee may grant a Stock Award pursuant to a Stock Bonus agreement in
     consideration for past services actually rendered to the Company or for its
     benefit.

          (d)  Vesting.  Shares of Company Common Stock sold or awarded under
     the Plan may, but need not, be subject to a repurchase option in favor of
     the Company in accordance with a vesting schedule to be determined by the
     Committee.

          (e)  Termination of Employment or Relationship as a Consultant.  In
     the event a Participant's Continuous Status as an Employee or Consultant
     terminates, the Company may repurchase or otherwise reacquire any or all of
     the shares of Company Common Stock held by that person which have not
     vested as of the date of termination under the terms of the Stock Bonus or
     restricted stock purchase agreement between the Company and such person.

9.  STOCK APPRECIATION RIGHTS.

     (a)  The Committee shall have full power and authority, exercisable in its
sole discretion, to grant Stock Appreciation Rights to Employees or Consultants
to the Company or its Affiliates under the Plan. Each such right shall entitle
the holder to a distribution based on the appreciation in the Fair Market Value
per share of a designated amount of Company Common Stock.

     (b)  Three types of Stock Appreciation Rights shall be authorized for
issuance under the Plan:

          (i)  Tandem Stock Appreciation Rights.  Tandem Rights will be granted
     appurtenant to an Option and will require the holder to elect between the
     exercise of the underlying Option for shares of Company Common Stock and
     the surrender, in whole or in part, of such Option for an appreciation
     distribution equal to the excess of (A) the Fair Market Value (on the date
     of Option surrender) of vested shares of Company Common Stock purchasable
     under the surrendered Option over (B) the aggregate exercise price payable
     for such shares.

                                       9
<PAGE>   10

          (ii)  Concurrent Stock Appreciation Rights.  Concurrent Rights will be
     granted appurtenant to an Option and may apply to all or any portion of the
     shares of Company Common Stock subject to the underlying Option and will be
     exercised automatically at the same time the Option is exercised for those
     shares. The appreciation distribution to which the holder of such
     concurrent right shall be entitled upon exercise of the underlying Option
     shall be in an amount equal to such portion as shall be determined by the
     Board or the Committee at the time of grant of the excess of (A) the
     aggregate Fair Market Value (at date of exercise) of the vested shares
     purchased under the underlying Option with such concurrent rights over (B)
     the aggregate exercise price paid for those shares.

          (iii)  Independent Stock Appreciation Rights.  Independent Rights may
     be granted independently of any Option and will entitle the holder upon
     exercise to an appreciation distribution equal in amount to the excess of
     (A) the aggregate Fair Market Value (at date of exercise) of a number of
     shares of Company Common Stock equal to the number of vested share
     equivalents exercised at such time (as described in subsection 8(c)(iii))
     hereof over (B) the aggregate Fair Market Value of such number of shares of
     Company Common Stock at the date of grant.

     (c)  The terms and conditions applicable to each Tandem Right, Concurrent
Right and Independent Right shall be as follows:

          (i)  TANDEM RIGHTS:

             A.  Tandem Rights may be tied to either Incentive Stock Options or
        Nonstatutory Stock Options. Each such right shall, except as
        specifically set forth below, be subject to the same terms and
        conditions applicable to the particular Option to which it pertains. If
        Tandem Rights are granted appurtenant to an Incentive Stock Option, they
        shall satisfy any applicable Treasury Regulations so as not to
        disqualify such Option as an Incentive Stock Option under the Code.

             B.  The appreciation distribution payable on the exercised Tandem
        Right shall be in cash in an amount equal to the excess of (i) the Fair
        Market Value (on the date of the Option surrender) of the number of
        shares of Company Common Stock covered by that portion of the
        surrendered Option in which the Optionee is vested over (ii) the
        aggregate exercise price payable for such vested shares.

          (ii)  CONCURRENT RIGHTS:

             A.  Concurrent Rights may be tied to any or all of the shares of
        Company Common Stock subject to any Incentive Stock Option or
        Nonstatutory Stock Option grant made under the Plan. A Concurrent Right
        shall, except as specifically set forth below, be subject to the same
        terms and conditions applicable to the particular option grant to which
        it pertains.

             B.  A Concurrent Right shall be automatically exercised at the same
        time as the underlying Option is exercised with respect to the
        particular shares of Company Common Stock to which the Concurrent Right
        pertains.

             C.  The appreciation distribution payable on an exercised
        Concurrent Right shall be in cash in an amount equal to such portion as
        shall be determined by the Board or the Committee at the time of grant
        of the excess of (i) the aggregate Fair Market Value (on the date the
        Option is exercised) of the vested shares of Company Common Stock
        purchased under the underlying Option which have Concurrent Rights
        appurtenant to them over (ii) the aggregate exercise price paid for such
        shares.

          (iii)  INDEPENDENT RIGHTS:

             A.  Independent Rights shall, except as specifically set forth
        below, be subject to the same terms and conditions applicable to
        Nonstatutory Stock Options as set forth in Section 6 hereof. They shall
        be denominated in share equivalents.

             B.  The appreciation distribution payable on the exercised
        Independent Right shall be in cash in an amount equal to the excess of
        (I) the aggregate Fair Market Value (on the date of the exercise of the
        Independent Right) of a number of shares of Company Common Stock equal
        to the number of share equivalents in which the holder is vested under
        such Independent Right, and with respect to which the holder is
        exercising the Independent Right on such date, over (II) the aggregate
        Fair
                                      10
<PAGE>   11

        Market Value (on the date of the grant of the Independent Right) of such
        number of shares of Company Common Stock.

          (iv) TERMS APPLICABLE TO TANDEM RIGHTS, CONCURRENT RIGHTS AND
     INDEPENDENT RIGHTS:

             A.  To exercise any outstanding Tandem, Concurrent or Independent
        Right, the holder must provide written notice of exercise to the Company
        in compliance with the provisions of the instrument evidencing such
        right.

             B.  If a Tandem, Concurrent, or Independent Right is granted to an
        individual who is at the time subject to Section 16(b) of the Exchange
        Act (a "Section 16(b) Insider"), then the instrument of grant shall
        incorporate all the terms and conditions at the time necessary to assure
        that the subsequent exercise of such right shall qualify for the
        safe-harbor exemption from short-swing profit liability provided by Rule
        16b-3.

             C.  Except as otherwise provided in this Section 9, no limitation
        shall exist on the aggregate amount of cash payments the Company may
        make under the Plan in connection with the exercise of Tandem,
        Concurrent or Independent Rights.

10.  OTHER STOCK-BASED AWARDS.

     The Committee shall have the right to grant other Awards based upon Company
Common Stock having such terms and conditions as the Committee may determine,
including the grant of shares based upon certain conditions and grant of
securities convertible into Company Common Stock.

11.  CANCELLATION AND RE-GRANT OF OPTIONS.

     (a) The Board or the Committee shall have the authority to effect, at any
time and from time to time, with the consent of the affected holders of Options
and/or Stock Appreciation Rights, (i) the repricing of any outstanding Options
and/or any Stock Appreciation Rights under the Plan and the grant in
substitution therefor of new Options and/or Stock Appreciation Rights under the
Plan covering the same or different numbers of shares of Company Common Stock,
but having an exercise price per share not less than eighty five percent (85%)
of the Fair Market Value (one hundred percent (100%)) of the Fair Market Value
in the case of an Incentive Stock Option or, in the case of an Incentive Stock
Option granted to a 10% stockholder (as described in subsection 5(c) hereof, not
less than one hundred ten percent (110%) of the Fair Market Value) per share of
Company Common Stock on the new grant date.

     (b) Shares of Company Common Stock subject to an Option or Stock
Appreciation Right canceled under this Section 11 shall continue to be counted
against the maximum award of Options and Stock Appreciation Rights permitted to
be granted to a person pursuant to subsection 5(c) hereof. The repricing of an
Option and/or Stock Appreciation Right under this Section 11, resulting in a
reduction of the exercise price, shall be deemed to be a cancellation of the
original Option and/or Stock Appreciation Right and the grant of a substitute
Option and/or Stock Appreciation Right; in the event of such repricing, both the
original and the substituted Options and Stock Appreciation Rights shall be
counted against the maximum awards of Options and Stock Appreciation Rights
permitted to be granted to a person pursuant to subsection 5(c) hereof. The
provisions of this subsection 11(b) shall be applicable only to the extent
required by Section 162(m) of the Code.

12.  COVENANTS OF THE COMPANY.

     (a) During the terms of the Stock Awards, the Company shall keep available
at all times the number of shares of Company Common Stock required to satisfy
such Stock Awards up to the number of shares of Company Common Stock authorized
under the Plan.

     (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of Company Common Stock under the Stock Awards; provided,
however, that this undertaking shall not require the Company to register under
the

                                      11
<PAGE>   12

Securities Act or any securities law of any state either the Plan, any Stock
Award or any stock issued or issuable pursuant to any such Stock Award. The
Company shall not be required to sell or issue any shares under any Stock Award
if the issuance of such shares shall constitute a violation by the holder of the
Stock Award or by the Company of any provision of any law or regulation of any
governmental authority. In the event the shares of Company Common Stock issuable
on exercise of Stock Award are not registered under the Securities Act, the
Company may imprint upon any certificate representing shares so issued any
legend which counsel for the Company considers necessary or advisable to comply
with the Securities Act and with applicable state securities laws. The Company
may, but shall in no event be obligated to, register any securities covered
hereby pursuant to the Securities Act; and in the event any shares are so
registered the Company may remove any legend on certificates representing such
shares.

13.  USE OF PROCEEDS FROM STOCK.

     Proceeds from the sale of Company Common Stock pursuant to Stock Awards
shall constitute general funds of the Company.

14.  MISCELLANEOUS.

     (a) The Committee shall have the power to accelerate the time at which a
Stock Award may first be exercised or the time during which a Stock Award or any
part thereof will vest, notwithstanding the provisions in the Stock Award
stating the time at which it may first be exercised or the time during which it
will vest.

     (b) Neither an Optionee nor any person to whom an Option is transferred
under subsection 6(d) hereof shall be deemed to be the holder of, or to have any
of the rights of a holder with respect to, any shares of Company Common Stock
subject to such Option unless and until such person has satisfied all
requirements for exercise of the Option pursuant to its terms.

     (c) Nothing in the Plan or any instrument executed or Stock Award granted
pursuant thereto shall confer upon any Employee, Director, Consultant, Optionee,
or other holder of Stock Awards any right to continue in the employ of the
Company or any Affiliate (or to continue acting as a Director or Consultant) or
shall affect the right of the Company or any Affiliate to terminate the
employment or relationship as a Director or Consultant of any Employee,
Director, Consultant or Optionee, with or without cause.

     (d) To the extent that the aggregate Fair Market Value (determined at the
time of grant) of Company Common Stock with respect to which Incentive Stock
Options are exercisable for the first time by any Optionee during any calendar
year under all plans of the Company and its Affiliates exceeds one hundred
thousand dollars ($100,000), the Options or portions thereof which exceed such
limit (according to the order in which they were granted) shall be treated as
Nonstatutory Stock Options.

15.  ADJUSTMENTS UPON CHANGE IN STOCK.

     In the event of any Change in Stock, the Plan will be appropriately
adjusted in the class(es) and maximum number of shares subject to the Plan
pursuant to subsection 4(a) hereof and the maximum number of shares subject to
Options and Stock Awards pursuant to subsection 5(c) hereof, and the outstanding
Stock Awards will be appropriately adjusted in the class(es) and number of
shares and price per share of stock subject to such outstanding Stock Awards.
Such adjustments shall be made by the Committee, the determination of which
shall be final, binding and conclusive.

16.  VESTING AND PAYMENT UPON CHANGE IN CONTROL.

     (a) After a merger of one or more corporations with or into the Company or
after a consolidation of the Company and one or more corporations in which the
stockholders of the Company immediately prior to such merger or consolidation
own after such merger or consolidation shares representing at least fifty
percent (50%) of the voting power of the Company or the surviving or resulting
corporation, as the case may be, each holder of an outstanding Option shall, at
no additional cost, be entitled upon exercise of such Option to receive in lieu
of the shares of Company Common Stock as to which such Option was exercisable
immediately prior to such event, the number and class of shares of stock or
other securities, cash or property (including, without

                                      12
<PAGE>   13

limitation, shares of stock or other securities of another corporation or
Company Common Stock) to which such holder would have been entitled pursuant to
the terms of the agreement of merger or consolidation if, immediately prior to
such merger or consolidation, such holder had been the holder of record of a
number of shares of Company Common Stock equal to the number of shares for which
such Option shall be so exercised.

     (b) Upon and following the occurrence of a Change of Control, the time for
exercise of each unvested installment of any then outstanding Option or Stock
Appreciation Right shall be accelerated, so that:

          (i) immediately upon such Change of Control, if the holder or optionee
     is then an employee or consultant of the Company, twenty-five percent (25%)
     of any such unvested installment shall be exercisable;

          (ii) on the date that is nine months after such Change in Control, if
     the holder or optionee is then an employee or consultant of the Company,
     one third (33 1/3%) of any installment of such Option or Stock Appreciation
     Right that has not yet vested in accordance with its original terms or by
     virtue of this Section 16 shall become exercisable;

          (iii) on the date that is eighteen months after such Change in
     Control, if the holder or optionee is then an employee or consultant of the
     Company, fifty percent (50%) of any installment of such Option or Stock
     Appreciation Right that has not yet vested in accordance with its original
     terms or by virtue of this Section 16 shall become exercisable; and

          (iv) on the second anniversary of such Change in Control, if the
     holder or optionee is then an employee or consultant of the Company, any
     remaining installment of such Option or Stock Appreciation Right that has
     not yet vested in accordance with its original terms or by virtue of this
     Section 16 shall become exercisable.

     The foregoing clauses (i) through (iv) are intended to provide for vesting
that is in addition to, and not in lieu of, the vesting schedule originally
provided in any Option or Stock Appreciation Right outstanding at the time of a
Change in Control, and, except to the extent accelerated by such clauses, each
such Option or Stock Appreciation Right shall continue to vest in accordance
with its original terms.

     (c) Upon the occurrence of a Change of Control, the restrictions and
conditions contained in any Stock Bonus granted to a then current Employee or
Consultant or restricted stock purchase agreement related to a Stock Award to
which a then current Employee or Consultant is a party shall automatically be
appropriately modified so that under the terms thereof additional shares of
Company Common Stock vest in a manner essentially equivalent to the additional
vesting provided for in Section 16(b) for Options and Stock Appreciation Rights.
The determination of the Committee as to such modifications shall be final,
binding and conclusive.

     The foregoing subparagraph (c) is intended to provide for vesting that is
in addition to, and not in lieu of, the vesting schedule originally provided in
any Stock Bonus or restricted stock purchase agreement related to a Stock Award
outstanding at the time of a Change in Control, and, except to the extent
accelerated by such clauses, each such Stock Bonus or restricted stock purchase
agreement related to a Stock Award shall continue to vest in accordance with its
original terms.

     (d) If the Company is merged with or into or consolidated with another
corporation, other than a merger or consolidation which would result in the
voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) more than fifty percent (50%) of
the combined voting power of the voting securities of the Company or such
surviving entity outstanding immediately after such merger or consolidation; or
if the Company is liquidated, or sells or otherwise disposes of substantially
all of its assets to another corporation while unexercised Options remain
outstanding under the Plan, then either in such event:

          (i) subject to the provisions of clause (iii) below, after the
     effective date of such merger, consolidation, liquidation, sale or
     disposition, as the case may be, each holder of an outstanding Option shall
     be entitled, upon exercise of such Option, to receive, in lieu of the
     shares of Company Common Stock as to which such Option was exercisable
     immediately prior to such event, the number and class of shares of stock or
     other securities, cash or property (including, without limitation, shares
     of stock or other
                                      13
<PAGE>   14

     securities of another corporation or common stock) to which such holder
     would have been entitled pursuant to the terms of the merger,
     consolidation, liquidation, sale or disposition if, immediately prior to
     such event, such holder had been the holder of a number of shares of
     Company Common Stock equal to the number of shares as to which such Option
     shall be so exercised; or

          (ii) the Committee may accelerate the time for exercise of some or all
     unexercised and unexpired Options or Stock Appreciation Rights so that from
     and after a date prior to the effective date of such merger, consolidation,
     liquidation, sale or disposition, as the case may be, specified by the
     Committee such accelerated Options or Stock Appreciation Rights shall be
     exercisable in full.

     (e) If, within two years following a Change in Control, the employment of
any Optionee who immediately prior to such Change in Control was employed by the
Company as an Officer (each such Optionee being hereafter referred to as a
"Designated Executive") shall be terminated by the Company other than for cause,
or shall be terminated by the Designated Executive for Good Reason, then in such
event all unvested Options, Stock Appreciation Rights, Stock Bonuses and other
Stock Awards held by such Designated Executive at the date of such termination
shall thereupon immediately become exercisable in full. For purposes of this
paragraph, "Good Reason" for termination by a Designated Executive of his
employment shall be deemed to have existed only if (i) within two years after a
Change in Control, the Company, or any successor entity then employing the
Designated Executive, shall materially diminish the responsibilities and
authority of the Designated Executive or, shall materially reduce the rate of
compensation of the Designated Executive (including by way of a change in the
method of determining the eligibility of such Designated Executive to earn bonus
or incentive compensation), in either case as compared with his responsibilities
and authority or rate of compensation, as the case may be, in effect immediately
prior to such Change in Control, and (ii) within thirty (30) days following such
diminution or reduction the Designated Executive shall resign from his
employment by the Company or such successor entity.

     (f) If, within two years following a Change in Control, a Non-Employee
Director is terminated or resigns from the Board of Directors for Good Reason,
then in such event all unvested Options held by such Non-Employee Director at
the date of such termination or resignation shall thereupon immediately become
exercisable in full. For purposes of this paragraph, "Good Reason" for
resignation by a Non-Employee Director shall be deemed to have existed only if
(i) within two years after a Change in Control, the Company, or any successor
entity, shall materially diminish the responsibilities and authority of the
Non-Employee Director or shall materially reduce the rate of compensation of the
Non-Employee Director, in either case as compared with his responsibilities and
authority or rate of compensation, as the case may be, in effect immediately
prior to such Change in Control, and (ii) within thirty (30) days following such
diminution or reduction the Non-Employee Director shall resign from his position
as a Director.

17.  AMENDMENT OF THE PLAN AND STOCK AWARDS.

     (a) The Board at any time, and from time to time, may amend the Plan.
However, except as provided in Section 14 hereof relating to adjustments upon
changes in stock, no amendment shall be effective unless approved by the
stockholders of the Company to the extent stockholder approval is necessary for
the Plan to satisfy the requirements of Section 422 of the Code, Rule 16b-3, or
the listing or eligibility for quotation requirements of the Nasdaq National
Market or any similar organization or of any national securities exchange upon
which shares of Company Common Stock are listed or eligible for trading.

     (b) The Board may in its sole discretion submit any other amendment to the
Plan for stockholder approval, including, but not limited to, amendments to the
Plan intended to satisfy the requirements of Section 162(m) of the Code and the
regulations promulgated thereunder regarding the exclusion of performance-based
compensation from the limit on corporate deductibility of compensation paid to
certain executive officers.

     (c) It is expressly contemplated that the Board may amend the Plan in any
respect the Board deems necessary or advisable to provide Optionees with the
maximum benefits provided or to be provided under the provisions of the Code and
the regulations promulgated thereunder relating to Incentive Stock Options
and/or to bring the Plan and/or Incentive Stock Options granted under it into
compliance therewith.

granted and (ii) such person consents in writing.

     (e) The Committee at any time, and from time to time, may amend the terms
of any one or more Stock Awards; provided, however, that the rights and
obligations under any Stock Award shall not be altered or impaired by any such
amendment unless (i) the Company requests the consent of the person to whom the
Stock Award was granted and (ii) such person consents in writing.

in effect shall not be impaired by suspension or termination of the Plan, except
with consent of the person to whom the Stock Award was granted.

19.  LOCK-UP AGREEMENT.

     The Committee may in its discretion specify upon granting an Option that
upon request of the Company or the underwriters managing any underwritten
offering of the Company's securities, the Optionee shall agree in writing that
for a period of time (not to exceed 180 days) from the effective date of any
registration of securities of the Company, the Optionee will not sell, make any
short sale of, loan, grant any option for the purchase of, or otherwise dispose
of any shares issued pursuant to the exercise of such Option, without the prior
written consent of the Company or such underwriters, as the case may be.

20.  GOVERNING LAW.

     The provisions of the Plan and all Stock Awards made hereunder shall be
governed by and interpreted in accordance with the internal laws of the
Commonwealth of Massachusetts without regard to any applicable conflicts of law
principles thereof.
