     5.  Eligibility.

         (a)  DSUs may be granted to any Employee and Options may be granted to
     any Employee, Consultant or Outside Director as the Committee may from time
     to time designate, provided that (i) Incentive Stock Options may be granted
     only to Employees, and (ii) Options may be granted to Outside Directors
     only in accordance with the provisions of Section 5(b) below. In selecting
     the individuals to whom Options and DSUs shall be granted, as well as in

     take into consideration such factors as it deems relevant in connection
     with accomplishing the purpose of this Plan. Subject to the provisions of
     Section 3 above a Grantee may, if he or she is otherwise eligible, be
     granted additional Options and/or DSUs if the Committee shall so determine.
     Subject to adjustment as provided in Section 11 below, during any calendar
     year, Options for no more than 500,000 Shares of Common Stock shall be
     granted to any individual Employee, Consultant or Outside Director, and
     DSUs for no more than 150,000 Shares of Common Stock shall be granted to
     any individual Employee.

         (b)  All grants of Options to Outside Directors under this Plan shall
     be made strictly in accordance with the following provisions:

         (i)   No person shall have any discretion to select which Outside
               Directors shall be granted options; provided, that nothing in
               this Plan shall be construed to prevent an Outside Director from
               declining to receive an Option under this Plan.

         (ii)  Each Outside Director who is first elected to the Board after the
               adoption of this Plan shall be automatically granted on the date
               of such election (whether by the stockholders or by the Board of

<PAGE>   4
               Directors) an Option to purchase 10,000 Shares (subject to
               adjustment as provided in Section 11 below). On the date of the
               Annual Meeting Stockholders of the Company in each calendar year,
               each Outside Director who is reelected at that meeting, or whose
               term of office does not expire at that meeting, shall be
               automatically granted an option to purchase 10,000 Shares
               (subject to adjustment as provided in Section 11 below); provided
               that no such automatic annual grant shall be made to an Outside
               Director (i) who is first elected to the Board at such Annual
               Meeting or was first elected to the Board within three months
               prior to such Annual Meeting, or (ii) if there are not sufficient
               Shares remaining and available to all Outside Directors eligible
               for an automatic grant at the time at which an automatic annual
               grant would otherwise be made under this Section 5(b)(ii).

         (iii) The terms of each Option granted under this Section 5(b)(ii)
               above shall be as follows:

                    (A)  the term of the option shall be ten (10) years;

                    (B)  the Option shall become exercisable cumulatively
                         with respect to one-third of the Shares on each of
                         the first, second and third anniversaries of the date
                         of grant; provided, however, that in no event shall any
                         option be exercisable prior to obtaining stockholder
                         approval of this Plan; and

                    (C)  the exercise price per share of Common Stock shall be
                         100% of the "Fair Market Value" (as defined in
                         Section 7(b) below) on the date of grant of the Option.

         (iv)  Subject to the limitation set forth in Section 5(a) above, each
               Outside Director may be granted additional Options at the
               discretion of the Board. Subject to the provisions of this Plan,
               the terms of such discretionary Options shall be set forth in the
               Option agreement.

     Notwithstanding anything to the contrary herein, no automatic grants of
     options shall be made under the Plan during the period commencing on
     November 5, 1999 and ending on the date of effectiveness, if any, of an
     amendment to the Corporation's Certificate of Incorporation providing for
     at least 120 million authorized shares of Common Stock, provided, however,
     that, in the event of adoption of such an amendment, any such automatic
     grants that would otherwise have been made during such period shall be made
     on the first business day following the effective date of the
     aforementioned amendment.

         (c)  Each Option granted under Section 5(b) above shall be a
     Nonstatutory Stock Option. Each other Option shall be designated in the
     written option agreement as either an Incentive Stock Option or a
     Nonstatutory Stock Option. Notwithstanding such designations, if and to the
     extent that the aggregate Fair Market Value of the Shares with respect to
     which Options designated as Incentive Stock Options are exercisable for the
     first time by any Grantee during any calendar year (under all plans of the
     Company) exceeds $100,000, such options shall be treated as Nonstatutory
     Stock Options. For purposes of this Section 5(c), Options shall be taken
     into account in the order in which they are granted, and the Fair Market
     Value of the Shares shall be determined as of the time the Option with
     respect to such Shares is granted.

          (d)  This Plan shall not confer upon any Grantee any right with
     respect to continuation of employment by or the rendition of services to
     the Company or any Parent or Subsidiary, nor shall it interfere in any way
     with his or her right or the right of the Company or any Parent or
     Subsidiary to terminate his or her employment or services at any time, with
     or without cause. The terms of this Plan or any Options or DSUs granted
     hereunder shall not be construed to give any Grantee the right to any
     benefits not specifically provided by this Plan or in any manner modify the
     Company's right to modify, amend or terminate any of its pension or
     retirement plans.

     6. Term of Plan. This Plan shall become effective upon the later to occur
of its adoption by the Board of Directors of the Company (such adoption to
include the approval of at least two Outside Directors) or its approval by vote
of the holders of a majority of the outstanding shares of the Company entitled
to vote on the adoption of this Plan, and shall terminate no later than August
31, 2003. No grants shall be made under this Plan after the date of termination
of this Plan. Any termination, either partially or wholly, shall not affect any
Options then outstanding under this Plan.

     7.  Exercise Price; Consideration and Tax Withholding.

         (a)   Exercise Price.  The per Share exercise price for the Shares to
     be issued pursuant to exercise of an Option shall be determined by the
     Committee as follows:

<PAGE>   5
                  (i)      In the case of an Incentive Stock Option granted to
                           any Employee, the per Share exercise price shall be
                           no less than 100% of the Fair Market Value per Share
                           on the date of grant, but if granted to an Employee
                           who, at the time of the grant of such Incentive Stock
                           Option, owns stock representing more than ten percent
                           (10%) of the voting power of all classes of stock of
                           the Company or any Parent or Subsidiary, the per
                           Share exercise price shall be no less than 110% of
                           the Fair Market Value per Share on the date of grant.

                  (ii)     In the case of an Incentive Stock Option granted to
                           any person other than an Outside Director, the per
                           Share exercise price shall be no less than 100% of
                           the Fair Market Value per Share on the date of grant,
                           but if granted to an Employee who, at the time of the
                           grant of such Incentive Stock Option, owns stock
                           representing more than ten percent (10%) of the
                           voting power of all classes of stock of the Company
                           or any Parent or Subsidiary, the per Share exercise
                           price shall be no less than 110% of the Fair Market
                           Value per Share on the date of grant.  The exercise
                           price of Options granted pursuant to Section 5(b)
                           above shall be 100% of the Fair Market Value on the
                           date of grant of the Option.

                  For purposes of this Section 7(a), if an Option is amended to
                  reduce the exercise price, the date of grant of such option
                  shall thereafter be considered to be the date of such
                  amendment.

                  (iii)    With respect to (i) or (ii) above, the per Share
                           exercise price is subject to adjustment as provided
                           in Section 11 below.

         (b) Fair Market Value. The "Fair Market Value" of the Common Stock
shall be determined by the Committee in its discretion; provided, that if the
Common Stock is listed on a stock exchange, the Fair Market Value per Share
shall be the closing price on such exchange on the date of grant of the Option
as reported in the Wall Street Journal (or, (i) if not so reported, as otherwise
reported by the exchange, and (ii) if not reported on the date of grant, then on
the last prior date on which a sale of the Common Stock was reported); or if not
listed on an exchange but traded on the National Association of Securities
Dealers Automated Quotation National Market System ("NASDAQ"), the Fair Market
Value per Share shall be the closing price per share of the Common Stock for the
date of grant, as reported in the Wall Street Journal (or, (i) if not so
reported, as otherwise reported by NASDAQ, and (ii) if not reported on the date
of grant, then on the last prior date on which a sale of the Common Stock was
reported); or, if the Common Stock is otherwise publicly traded, the mean of the
closing bid price and asked price for the last known sale.

     (c) Consideration.  The consideration to be paid for the Shares to be
issued upon exercise of an Option, including the method of payment, shall be
determined by the Committee (and in the case of an Incentive Stock Option, shall
be determined at the time of grant) and may consist entirely of (i) cash; (ii)
check; (iii) the Grantee's personal interest bearing full recourse promissory
note with such terms and provisions as the Committee may authorize (provided
that no person who is not an Employee of the Company may purchase Shares with a
promissory note); (iv) other Shares of Common Stock which (X) either have been
owned by the Grantee for more than six (6) months on the date of surrender or
were not acquired directly or indirectly from the Company, and (Y) have a Fair
Market Value on the date of surrender (determined without regard to any
limitations on transferability imposed by securities laws) equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised; (v) any combination of such methods of payment; or (vi) such other
consideration and method of payment for the issuance of Shares to the extent
permitted under applicable laws.

     (d)  Withholding.  No later than the date as of which an amount first
becomes includable in the gross income of the Grantee for Federal income tax
purposes with respect to an option, the Grantee shall pay to the Company (or
other entity identified by the Committee), or make arrangements satisfactory to
the Company or other entity identified by the Committee regarding the payment
of, any Federal, state, local or foreign taxes of any kind required by law to be
withheld with respect to such amount required in order for the Company to obtain
a current deduction. Unless otherwise determined by the Committee, withholding
obligations may be settled with Common Stock, including Common Stock underlying
the subject option, provided that any applicable requirements under Section 16
of the Exchange Act are satisfied so as to avoid liability thereunder. The
obligations of the Company under this Plan shall be conditional upon such
payment or arrangements, and the Company shall, to the extent permitted by law,
have the right to deduct any such taxes from any payment otherwise due to the
Grantee.

     8.   Options.

          (a)   Term of Option. The term of each Option granted (other than an
Option granted under Section 5(b) above) shall be for a period of no more than
ten (10) years from the date of grant thereof or such shorter term as may be
provided in the Option agreement. However, in the case of an Option granted to a
Grantee who, at the time the Option is granted, owns stock representing more
than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant thereof or such shorter time as may be provided in
the Option Agreement.

          (b)   Exercise of Options.

          (i)   Procedure for Exercise; Rights as a Shareholder. Any Option
                granted under this Plan (other than an Option granted pursuant
                to Section 5(b) above) shall be exercisable at such times and
                under such conditions as determined by the Committee, including
                performance criteria with respect to the Company and/or the
                Grantee, and as shall otherwise be permissible under the terms
                of this Plan.

                An Option may not be exercised for a fraction of a Share.

                An Option shall be deemed to be exercised when written notice of
                such exercise has been given to the Company in accordance with
                the terms of the Option by the person entitled to exercise the
                Option and full payment for the Shares with respect to which the
                Option is exercised has been received by the Company. Full
                payment may, as authorized by the Committee, consist of any
                consideration and method of payment allowable under Section 7 of
                this Plan. Until the issuance (as evidenced by the appropriate
                entry on the books of the Company or of a duly authorized
                transfer agent of the Company) of the stock certificate
                evidencing such Shares, no right to vote or receive dividends or
                any other rights as a shareholder shall exist with respect to
                the Optioned Stock, notwithstanding the exercise of the Option.
                The Company shall issue (or cause to be issued) such stock
                certificate promptly upon exercise of the Option If the exercise
                of an Option is treated in part as the exercise of an Incentive
                Stock Option and in part as the exercise of a Nonstatutory Stock
                Option pursuant to Section 5(b) above, the Company shall issue a
                separate stock certificate evidencing the Shares treated as
                acquired upon exercise of an Incentive Stock Option and a
                separate stock certificate evidencing the Shares treated as
                acquired upon exercise of a Nonstatutory Stock Option and shall
                identify each such certificate accordingly in its stock transfer
                records. No adjustment will be made for a dividend or other
                right for which the record date is prior to the date the stock
                certificate is issued, except as provided in Section of this
                Plan.

                Exercise of an Option in any manner shall result in a decrease
                in the number of Shares which thereafter may be available, both
                for purposes of this Plan and for sale under the Option, by the
                number of Shares as to which the Option is exercised.

          (ii)  Method of Exercise.  A Grantee may exercise an Option, in whole
                or in part, at any time during the option period by the
                Grantee's giving written notice of exercise on a form provided
                by the Committee (if available) to the Company specifying the
                number of shares of Common Stock subject to the Option to be
                purchased. Such notice shall be accompanied by payment in full
                of the purchase price by cash or check or such other form of
                payment as the Company may accept. If approved by the Committee,
                payment in full or in part may also be made (A) by delivering
                Common Stock already owned by the Grantee having a total Fair
                Market Value on the date of such delivery equal to the exercise
                price of the subject Option; (B) by the execution and delivery
                of a note or other evidence of indebtedness (and any security
                agreement thereunder) satisfactory to the Committee; (C) by
                authorizing the Company to retain shares of Common Stock which
                would otherwise be issuable upon exercise of the Option having a
                total Fair Market Value on the date of delivery equal to the
                exercise price of the subject Option; (D) by the delivery of
                cash by a broker-dealer to whom the Grantee has submitted an
                irrevocable notice of exercise (in accordance with Part 220,
                Chapter II, Title 12 of the Code of Federal Regulations,
                so-called "cashless" exercise); or (E) by any combination of the
                foregoing. In the case of an Incentive Stock Option, the right
                to make a payment in the form of already owned shares of Common
                Stock of the same class as the Common Stock subject to the
                Option may be authorized only at the time the Option is granted.
                No shares of Common Stock shall be issued until full payment
                therefor has been made. A Grantee

<PAGE>   7
                shall have all of the rights of a shareholder of the Company
                holding the class of Common Stock that is subject to such Option
                (including, if applicable, the right to vote the shares and the
                right to receive dividends), when the Grantee has given written
                notice of exercise, has paid in full for such shares and such
                shares have been recorded on the Company's official shareholder
                records as having been issued or transferred.

          (iii) Termination of Status as an Employee, Consultant or Outside
                Director. If a Grantee's Continuous Status as an Employee,
                Consultant or Outside Director (as the case may be) is
                terminated for any reason whatever, such Grantee may, but only
                within such period of time as provided in the Option agreement,
                after the date of such termination (but in no event later than
                the date of expiration of the term of such Option as set forth
                in the Option agreement), exercise the Option to the extent that
                such Employee, Consultant or Outside Director was entitled to
                exercise it at the date of such termination pursuant to the
                terms of the Option agreement. To the extent that such Employee,
                Consultant or Outside Director was not entitled to exercise the
                Option at the date of such termination, or if such Employee,
                Consultant or Outside Director does not exercise such Option
                (which such Employee, Consultant or Outside Director was
                entitled to exercise) within the time specified in the Option
                agreement, the Option shall terminate.

          (iv)  Company Loan or Guarantee. Upon the exercise of any Option and
                subject to the pertinent Option agreement and the discretion of
                the Committee, the Company may at the request of the Grantee;
                (A) lend to the Grantee, with recourse, an amount equal to such
                portion of the option exercise price as the Committee may
                determine; or (B) guarantee a loan obtained by the Grantee from
                a third-party for the purpose of tendering the option exercise
                price.

     9.   Deferred Stock Units.

          (a)   Grant of Deferred Stock Units.  Subject to such terms and
     conditions as the Committee shall determine, an Employee may be granted
     Deferred Stock Units ("DSUs"), entitling the Employee to receive Shares of
     Common Stock without any payment in cash or property in one or more
     installments at a future date or dates. DSUs shall be non-transferable and
     may be conditioned on such matters as the Committee shall determine,
     including continued employment or attainment of performance goals. No
     Shares of Common Stock will be issued at the time an award of DSUs is made
     and the Company shall not be required to set aside a fund for the payment
     of any such award. The Company will establish a separate recordkeeping
     account for the Employee and will record in such account the number of DSUs
     awarded to the Grantee. The Committee may permit Grantees to further defer
     receipt of Shares of Common Stock payable with respect to DSUs.

          (b)   Rights as a Stockholder; Dividend Equivalents. A Grantee shall
     not have any right in respect of DSUs awarded pursuant to the Plan to vote
     on any matter submitted to the Company's stockholders until such time as
     the Shares of Common Stock attributable to such DSUs have been issued to
     such Grantee or his beneficiary. The Committee will determine whether and
     to what extent to pay dividend equivalents to Grantees of DSUs.

          (c)   Settlement of Deferred Stock. An Employee shall receive one
     share of Common Stock for each vested DSU on such date or dates and/or upon
     the occurrence of such event as the Committee may specify in the award
     agreement or on such later date as may be elected by the Grantee in a
     deferral election made accordance with the rules and procedures established
     by the Committee. If a Grantee's Continuous Status as an Employee is
     terminated for any reason, the Grantee shall immediately forfeit all rights
     with respect to any nonvested DSUs credited to his or her account.

     10. Non-transferability of Options and DSUs. Except as otherwise provided
in an Option Agreement, Options and DSUs granted hereunder shall by their terms
not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any
manner other than by will or the laws of descent and distribution. Except as
otherwise provided in an Option Agreement, an Option may be exercised during the
Grantee's lifetime only by the Grantee.

          Notwithstanding the foregoing, upon written approval of the
Compensation Committee, a Grantee may transfer Options to any Family Member (as
defined below), to any trust in which the Grantee and/or the Grantee's Family
Members have more than fifty percent (50%) of the beneficial interest, any
foundation in which the Grantee and/or the Grantee's Family Members control the
management of assets, and any other entity in which the Grantee and/or the
Grantee's Family Members own more than fifty percent of the voting interest;
provided that such transfer is not a transfer for value. For purposes of the
preceding sentence, the following transfers will not be considered prohibited
transfers for value:

<PAGE>   8
          (i)   A transfer under a domestic relations order in settlement of
                marital property rights; and

          (ii)  A transfer to an entity in which more than fifty percent (50%)
                of the voting interests are owned by the Grantee and/or the
                Grantee's Family Members in exchange for an interest in that
                entity.

          A "Family Member" shall include any child, stepchild, grandchild,
parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew,
mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or
sister-in-law, including any adoptive relationships, or any other person sharing
the Grantee's household (other than a tenant or employee).

          11.   Adjustments Upon Changes in Capitalization or Merger.

                (a) Capitalization. Subject to any required action by the
          stockholders of the Company, the number of shares of Common Stock
          which have been authorized for issuance under this Plan but as to
          which no Options or DSUs have yet been granted or which have been
          returned to this Plan upon cancellation or expiration of an Option, or
          forfeiture of a DSU, the maximum number of Shares for which Options or
          DSUs may be granted to any Employee, Consultant or Outside Director
          during any calendar year (as provided in Section 5(a) above), and the
          number of shares of Common Stock subject to each outstanding Option
          and DSU, as well as the exercise price per share of Common Stock
          covered by each outstanding Option, shall be proportionately adjusted
          for any increase or decrease in the number of shares of Common Stock
          issued as a result of a stock split, reverse stock split, stock
          dividend, combination or reclassification of the Common Stock of the
          Company or the payment of a stock dividend with respect to the Common
          Stock. Except as expressly provided herein, no issuance by the Company
          of shares of stock of any class, or securities convertible into shares
          of stock of any class, shall affect, and no adjustment by reason
          thereof shall be made with respect to, the number or exercise price of
          shares of Common Stock subject to an Option or DSU.

                (b)  Dissolution or Liquidation.  In the event of the proposed
          dissolution or liquidation of the Company, each Option will terminate
          immediately prior to the consummation of such proposed action, unless
          otherwise provided by the Committee. The Committee may, in the
          exercise of its sole discretion in such instances, declare that any
          Option shall terminate as of a date fixed by the Committee and give
          each Grantee the right to exercise his or her Option as to all or any
          part of the Optioned Stock, including Shares as to which the Option
          would not otherwise be exercisable. In the event of a proposed
          dissolution or liquidation of the Company, each nonvested DSU shall be
          forfeited, unless otherwise provided by the Committee, and the
          deferred Shares of Common Stock payable with respect to each vested
          DSU shall be issued to the Grantee immediately prior to the
          consummation of the proposed action notwithstanding any deferral
          election made by the Grantee.

                (c)  Change of Control.  For purposes of this Plan, a "Change of
          Control" shall be deemed to have occurred if (i) if any corporation,
          person or other entity (other than the Company, a majority-owned
          subsidiary of the Company or any of its subsidiaries, or an employee
          benefit plan (or related trust) sponsored or maintained by the
          Company), including a "group" as defined in Section 13(d)(3) of the
          Exchange Act, becomes the beneficial owner of stock (other than as a
          result of a purchase of such stock from the Company) representing more
          than 25% of the combined voting power of the Company's then
          outstanding securities; (ii) (A) the stockholders of the Company
          approve a definitive agreement to merge or consolidate the Company
          with or into another corporation other than a majority-owned
          subsidiary of the Company, or to sell or otherwise dispose of all or
          substantially all of the Company's assets, and (B) the persons who
          were the members of the Board prior to such approval do not represent
          a majority of the directors of the surviving, resulting or acquiring
          entity or the parent thereof; or (iii) during any period of two
          consecutive years, individuals who at the beginning of such period
          constitute the Board and any new director whose election by the Board
          or nomination for election by the Company's stockholders was approved
          by a vote of at least two-thirds of the directors then still in office
          who either were directors at the beginning of such period or whose
          election or nomination for election was previously so approved, cease
          for any reason to constitute a majority of the Board. With respect to
          Options granted to any Employee or Consultant prior to February 15,
          2000 and with respect to any Options granted to any Outside Director
          (whether granted before or after February 15, 2000), each such Option
          that is outstanding immediately prior to a Change of Control shall
          become exercisable in full regardless of any vesting conditions
          otherwise expressed in the award agreement. Except as otherwise
          provided in an award agreement with respect to Options or DSUs granted
          to an Employee or Consultant on or after February 15, 2000 and prior
          to a Change of Control, each such outstanding DSU shall vest, and each
          such outstanding Option shall become exercisable in full, regardless
          of any vesting conditions otherwise expressed in the award agreement,
          upon the

<PAGE>   9
          Employee's or Consultant's termination of employment with the Company
          following the Change of Control of the Company if the Employee's or
          Consultant's employment is terminated by the Company without Cause or
          by the Employee or Consultant for Good Reason.

                (d)  Purchased Shares.  No adjustment under this Section 11
          shall apply to any purchased Shares already deemed issued at the time
          any adjustment would occur.

                (e)  Notice of Adjustments. Whenever the purchase price or the
          number or kind of securities issuable upon the exercise of the Option
          shall be adjusted pursuant to Section 11, the Company shall give each
          Grantee written notice setting forth, in reasonable detail, the event
          requiring the adjustment, the amount of the adjustment, and the method
          by which such adjustment was calculated.

                (f)  Certain Cash Payments.  If a Grantee would not be permitted
          to exercise an Option or any portion thereof (for purposes of this
          subsection (f) only, each such Option being referred to as a "Subject
          Option") or dispose of the Shares received upon the exercise thereof
          without loss or liability (other than a loss or liability for the
          exercise price, applicable withholding or any associated transactional
          cost), or if the Board determines that the Grantee may not be
          permitted to exercise the same rights or receive the same
          consideration with respect to the sale of the Company as a shareholder
          of the Company with respect to any Subject Options or portion thereof
          or the Shares received upon the exercise thereof, then notwithstanding
          any other provision of this Plan and unless the Committee shall
          provide otherwise in an agreement with such Grantee with respect to
          any Subject Options, such Grantee shall have the right, whether or not
          the Subject Option is fully exercisable or may be otherwise realized
          by the Grantee, by giving notice during the 60-day period from and
          after a Sale to the Company, to elect to surrender all or part of any
          Subject Options to the Company and to receive cash, within 30 days of
          such notice, in an amount equal to the amount by which the "Sale
          Price" (as defined herein) per share of Common Stock on the date of
          such election shall exceed the amount which the Grantee must pay to
          exercise the Subject Options per share of Common Stock under such
          Subject Options (the "Spread") multiplied by the number of shares of
          Common Stock granted under the Subject Options as to which the right
          granted hereunder shall be applicable and shall have been exercised;
          provided, however, that if the end of such 60-day period from and
          after a sale of the Company is within six months of the date of grant
          of a Subject Option held by a Grantee (except a Grantee who has
          deceased during such six month period) who is an officer or director
          of the Company (within the meaning of Section 16(b) of the Exchange
          Act), such Subject Option shall be canceled in exchange for a payment
          to the Grantee, effective on the day which is six months and one day
          after the date of grant of such Subject Option, equal to the Spread
          multiplied by the number of shares of Common Stock granted under the
          Subject Option. With respect to any Grantee who is an officer or
          director of the Company (within the meaning of Section 16(b) of the
          Exchange Act), the 60-day period shall be extended, if necessary, to
          include the "window period" of Rule 16(b)-3 which first commences on
          or after the date of the sale of the Company, and the Committee shall
          have sole discretion, if necessary, to approve the Grantee's exercise
          hereunder and the date on which the Spread is calculated may be
          adjusted, if necessary, to a later date if necessary to avoid
          liability to such Grantee under Section 16(b). For purposes of the
          Plan, "Sale Price" means the higher of (a) the highest reported sales
          price of a share of Common Stock in any transaction reported on the
          principal exchange on which such shares are listed or on NASDAQ during
          the 60-day period prior to and including the date of a sale of the
          Company or (b) if the sale of the Company is the result of a tender or
          exchange offer or a corporate transaction, the highest price per share
          of Common Stock paid in such tender or exchange offer or a corporate
          transaction, except that, in the case of Incentive Stock Options, such
          price shall be based only on the Fair Market Value of the Common Stock
          on the date such Incentive Stock Option is exercised. To the extent
          that the consideration paid in any such transaction described above
          consists all or in part of securities or other non-cash consideration,
          the value of such securities or other non-cash consideration shall be
          determined in the sole discretion of the Committee.

                (g)  Mitigation of Excise Tax.  If any payment or right accruing
          to a Grantee under this Plan (without the application of this
          Section), either alone or together with other payments or rights
          accruing to the Grantee from the Company or an affiliate ("Total
          Payments") would constitute a "parachute payment" (as defined in
          Section 280G of the Code and regulations thereunder), the Committee
          may in each particular instance determine to (a) reduce such payment
          or right to the largest amount or greatest right that will result in
          no portion of the amount payable or right accruing under the Plan
          being subject to an excise tax under Section 4999 of the Code or being
          disallowed as a deduction under Section 280G of the Code, or (b) take
          such other actions, or make such other arrangements or payments with
          respect to any such payment or right as the Committee may determine in
          the circumstances. Any such determination shall be made by the
          Committee in the exercise of its sole discretion, and such
          determination shall be conclusive and binding on the Grantee. The
          Grantee shall cooperate as may be requested by the Committee

<PAGE>   10
          in connection with the Committee's determination, including providing
          the Committee with such information concerning such Grantee as the
          Committee may deem relevant to its determination.

     12.  Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date on which the Committee makes the determination
granting such Option. Notice of the determination shall be given to each
Employee, Consultant or Outside Director to whom an Option is so granted within
a reasonable time after the date of such grant. If the Committee cancels, with
the consent of Grantee, any Option granted under this Plan, and a new Option is
substituted therefor, the date that the canceled Option was originally granted
shall be the date used to determine the earliest date for exercising the new
substituted Option under Section 7 so that the Grantee may exercise the
substituted Option at the same time as if the Grantee had held the substituted
Option since the date the canceled Option was granted.

     13.  Amendment and Termination of Plan.

          (a) Amendment and Termination. The Board or the Committee may amend,
     waive or terminate this Plan from time to time in such respects as it shall
     deem advisable; provided that, to the extent necessary to comply with the
     applicable rules and regulations of the stock exchange or market on which
     the Common Stock is then listed for trading or with Section 422 of the Code
     (or any successor or applicable law or regulation), the Company shall
     obtain stockholder approval of any Plan amendment in such manner and to
     such a degree as is required by the rule, regulation or law.

          (b)   Effect of Amendment or Termination. Any such amendment or
     termination of this Plan shall not affect Options or DSUs already granted
     and such Options and DSUs shall remain in full force and effect as if this
     Plan had not been amended or terminated, unless mutually agreed otherwise
     between the Grantee and the Committee, which agreement must be in writing
     and signed by the Grantee and the Company.

     14.  Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to a DSU or to the exercise of an Option unless the exercise of such
Option and the issuance and delivery of such Shares pursuant to a DSU or upon
exercise of an Option hereto shall comply with all relevant provisions of law,
including, without limitation, the Securities Act of 1933, as amended, the
Exchange Act, and the rules and regulations promulgated thereunder, and the
requirements of any stock exchange upon which the Shares may then be listed, and
shall be further subject to the approval of counsel for the Company with respect
to such compliance.

          As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

     15.  Restrictions on Shares. Shares of Common Stock issued in respect of
DSUs or upon exercise of an Option shall be subject to the terms and conditions
specified herein and to such other terms, conditions and restrictions as the
Committee in its discretion may determine or provide in the grant. The Company
shall not be required to issue or deliver any certificates for shares of Common
Stock, cash or other property prior to (i) the listing of such shares on any
stock exchange (or other public market) on which the Common Stock may then be
listed (or regularly traded), (ii) the completion of any registration or
qualification of such shares under federal or state law, or any ruling or
regulation of any government body which the Committee determines to be necessary
or advisable, and (iii) the satisfaction of any applicable withholding
obligation in order for the Company or an affiliate to obtain a deduction with
respect to the exercise of an Option. The Company may cause any certificate for
any share of Common Stock to be delivered to be properly marked with a legend or
other notation reflecting the limitations on transfer of such Common Stock as
provided in this Plan or as the Committee may otherwise require. The Committee
may require any person exercising an Option or receiving shares in respect of
DSUs to make such representations and furnish such information as it may
consider appropriate in connection with the issuance or delivery of the shares
of Common Stock in compliance with applicable law or otherwise. Fractional
shares shall not be delivered, but shall be rounded to the next lower whole
number of shares.

     16.  Shareholder Rights. No person shall have any rights of a shareholder
as to shares of Common Stock subject to an Option or DSU until, after proper
exercise of the Option or other action required or, in the case of DSUs, after
the conditions for delivery of Shares subject to DSUs have been satisfied and
such shares shall have been recorded on the Company's official shareholder
records as having been issued or transferred. Subject to the preceding Section
and upon exercise of the Option or any portion thereof or satisfaction of the
conditions for delivery of Shares subject to DSUs, the Company will have thirty
(30) days in which to issue the shares, and the Grantee will not be treated as a
shareholder for any purpose whatsoever prior to such issuance. No adjustment
shall be made for cash dividends or other rights for which the

<PAGE>   11
record date is prior to the date such shares are recorded as issued or
transferred in the Company's official shareholder records, except as provided
herein or in an agreement.

     17.  Best Efforts To Register. If there has been a public offering, the
Company may register under the Securities Act the Common Stock delivered or
deliverable pursuant to Options on Commission Form S-8 if available to the
Company for this purpose (or any successor or alternate form that is
substantially similar to that form to the extent available to effect such
registration), in accordance with the rules and regulations governing such
forms, as soon as such forms are available for registration to the Company for
this purpose. The Company will, if it so determines, use its good faith efforts
to cause the registration statement to become effective as soon as possible and
will file such supplements and amendments to the registration statement as may
be necessary to keep the registration statement in effect until the earliest of
(a) one year following the expiration of the option period of the last Option
outstanding (or issuance of the last Share subject to an outstanding DSU), (b)
the date the Company is no longer a reporting company under the Exchange Act and
(c) the date all Grantees have disposed of all shares delivered pursuant to any
Option or DSU. The Company may delay the foregoing actions at any time and from
time to time if the Committee determines in its discretion that any such
registration would materially and adversely affect the Company's interests or if
there is no material benefit to Grantees.

     18.  Reservation of Shares. The Company, during the term of this Plan, will
at all times reserve and keep available such number of Shares as shall be
sufficient to permit the exercise of all Options outstanding under this Plan and
the issuance of Shares subject to all outstanding DSUs. The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained for any reason.

     19.  Option and DSU Agreements.  Options and DSUs shall be evidenced by
written agreements in such form as the Committee shall approve.

     20.  Information to Grantees. To the extent required by applicable law, the
Company shall provide to each Grantee, during the period for which such Grantee
has one or more Options or DSUs outstanding, copies of all annual reports and
other information which are provided to all stockholders of the Company. Except
as otherwise noted in the foregoing sentence, the Company shall have no
obligation or duty to affirmatively disclose to any Grantee, and no Grantee
shall have any right to be advised of, any material information regarding the
Company or any Parent or Subsidiary at any time prior to, upon or otherwise in
connection with, the exercise of an Option.

     21.  Funding.  Benefits payable under this Plan to any person shall be paid
directly by the Company. The Company shall not be required to fund or otherwise
segregate assets to be used for payment of benefits under this Plan.

     22.  Controlling Law.  This Plan shall be governed by the laws of the State
of Delaware applicable to contracts made and performed wholly in Delaware
between Delaware residents.
