                            2000 STOCK INCENTIVE PLAN



        SECTION 1. ESTABLISHMENT AND PURPOSE.

        The Plan was adopted by the Board of Directors effective as of the date
of the Company's initial public offering. The Plan is intended to serve as the
successor to the Predecessor Plans, and to incorporate and treat as outstanding
under the Plan all options outstanding under the Predecessor Plans as of the
Plan's effective date. The purpose of the Plan is to promote the long-term
success of the Company and the creation of stockholder value by (a) encouraging
Employees, Outside Directors and Consultants to focus on critical long-range
objectives, (b) encouraging the attraction and retention of Employees, Outside
Directors and Consultants with exceptional qualifications and (c) linking
Employees, Outside Directors and Consultants directly to stockholder interests
through increased stock ownership. The Plan seeks to achieve this purpose by
providing for Awards in the form of Restricted Shares, Stock Units, Options
(which may constitute incentive stock options or nonstatutory stock options) or
stock appreciation rights.

        SECTION 2. DEFINITIONS.

        (a) "Affiliate" shall mean any entity other than a Subsidiary, if the
Company and/or one of more Subsidiaries own not less than 50% of such entity.

        (b) "Award" shall mean any award of an Option, a SAR, a Restricted Share
or a Stock Unit under the Plan.

        (c) "Board of Directors" shall mean the Board of Directors of the
Company, as constituted from time to time.

        (d) "Change in Control" shall mean the occurrence of any of the
following events:

                (i) A change in the composition of the Board of Directors
        occurs, as a result of which fewer than two-thirds of the incumbent
        directors are directors who either:

                        (A) Had been directors of the Company on the "look-back
                date" (as defined below) (the "original directors"); or

                        (B) Were elected, or nominated for election, to the
                Board of Directors with the affirmative votes of at least a
                majority of the aggregate of the original directors who were
                still in office at the time of the election or nomination and
                the directors whose election or nomination was previously so
                approved (the "continuing directors"); or

                (ii) Any "person" (as defined below) who by the acquisition or
        aggregation of securities, is or becomes the "beneficial owner" (as
        defined in Rule 13d-3 under the Exchange Act), directly or indirectly,
        of securities of the Company representing 50% or


                                      -1-
<PAGE>   7

        more of the combined voting power of the Company's then outstanding
        securities ordinarily (and apart from rights accruing under special
        circumstances) having the right to vote at elections of directors (the
        "Base Capital Stock"); except that any change in the relative beneficial
        ownership of the Company's securities by any person resulting solely
        from a reduction in the aggregate number of outstanding shares of Base
        Capital Stock, and any decrease thereafter in such person's ownership of
        securities, shall be disregarded until such person increases in any
        manner, directly or indirectly, such person's beneficial ownership of
        any securities of the Company; or

                (iii) The consummation of a merger or consolidation of the
        Corporation with or into another entity or any other corporate
        reorganization, if persons who were not stockholders of the Company
        immediately prior to such merger, consolidation or other reorganization
        own immediately after such merger, consolidation or other reorganization
        50% or more of the voting power of the outstanding securities of each of
        (A) the continuing or surviving entity and (B) any direct or indirect
        parent corporation of such continuing or surviving entity; or

                (iv) The sale, transfer or other disposition of all or
        substantially all of the Company's assets.

        For purposes of subsection (d)(i) above, the term "look-back" date shall
mean the later of (1) July 11, 2000 or (2) the date 24 months prior to the date
of the event that may constitute a Change in Control.

        For purposes of subsection (d)(ii) above, the term "person" shall have
the same meaning as when used in Sections 13(d) and 14(d) of the Exchange Act
but shall exclude (1) a trustee or other fiduciary holding securities under an
employee benefit plan maintained by the Company or a Parent or Subsidiary and
(2) a corporation owned directly or indirectly by the stockholders of the
Company in substantially the same proportions as their ownership of the Stock.

        Any other provision of this Section 4(d) notwithstanding, a transaction
shall not constitute a Change in Control if its sole purpose is to change the
state of the Company's incorporation or to create a holding company that will be
owned in substantially the same proportions by the persons who held the
Company's securities immediately before such transaction.

        (e) "Code" shall mean the Internal Revenue Code of 1986, as amended.

        prices quoted for such date by the principal automated inter-dealer

                (viii) To prescribe the terms and conditions of each Option,
        including (without limitation) the Exercise Price, the vesting or
        duration of the Option (including accelerating the vesting of the
        Option), to determine whether such Option is to be classified as an ISO
        or as a Nonstatutory Option, and to specify the provisions of the Stock
        Option Agreement relating to such Option;

                (ix) To amend any outstanding Stock Purchase Agreement or Stock
        Option Agreement, subject to applicable legal restrictions and to the
        consent of the Offeree or Optionee who entered into such agreement;

                (x) To prescribe the consideration for the grant of each Option
        or other right under the Plan and to determine the sufficiency of such
        consideration;

                (xi) To determine the disposition of each Option or other right
        under the Plan in the event of an Optionee's or Offeree's divorce or
        dissolution of marriage;

                (xii) To determine whether Options or other rights under the
        Plan will be granted in replacement of other grants under an incentive
        or other compensation plan of an acquired business;

                (xiii) To correct any defect, supply any omission, or reconcile
        any inconsistency in the Plan, any Stock Option Agreement or any Stock
        Purchase Agreement; and

                (xiv) To take any other actions deemed necessary or advisable
        for the administration of the Plan.

Subject to the requirements of applicable law, the Committee may designate
persons other than members of the Committee to carry out its responsibilities
and may prescribe such conditions and limitations as it may deem appropriate,
except that the Committee may not delegate its authority with regard to the
selection for participation of or the granting of Options or other rights under
the Plan to persons subject to Section 16 of the Exchange Act. All decisions,
interpretations and other actions of the Committee shall be final and binding on
all Offerees, all Optionees, and all persons deriving their rights from an
Offeree or Optionee. No member of the Committee shall be liable for any action
that he has taken or has failed to take in good faith with respect to the Plan,
any Option, or any right to acquire Shares under the Plan.

        SECTION 4. ELIGIBILITY.

        (a) General Rule. Only Employees shall be eligible for the grant of
ISOs. Only Employees, Consultants and Outside Directors shall be eligible for
the grant of Restricted Shares, Stock Units, NSOs or SARs, and grants to Outside
Directors shall comply with the provisions of Section 4(b).

        (b) Outside Directors. Any other provision of the Plan notwithstanding,
the participation of Outside Directors in the Plan shall be subject to the
following restrictions:

                (i) Outside Directors shall only be eligible for the grant of
        Restricted Shares, Stock Units, Nonstatutory Options and SARs.

                (ii) Each Outside Director who first joins the Board of
        Directors after the date of adoption of the Plan shall receive a
        Nonstatutory Option, subject to approval of the Plan by the Company's
        stockholders, to purchase thirty thousand (30,000) Shares (subject to
        adjustment under Section 12) on the first business day after his or her
        election or appointment to the Board of Directors.

                (iii) On the first business day following the conclusion of each
        regular annual meeting of the Company's stockholders after such Outside
        Director's appointment or election to the Board of Directors, commencing
        with the annual meeting occurring after the adoption of the Plan, each
        Outside Director who will continue serving as a member of the Board of
        Directors thereafter shall receive an Option to purchase seven thousand
        five hundred (7,500) Shares, subject to adjustment under Section 12.
        Each Outside Director who is not initially elected at a regular annual
        meeting of the Company's stockholders shall receive an Option to
        purchase a pro rata portion of seven thousand five hundred (7,500)
        Shares, subject to adjustment under Section 12, within ten business days
        of his or her election based on the number of full months remaining from
        date of election until the next regular annual meeting of the Company's
        stockholders divided by 12. Any fractional shares resulting from such
        calculation shall be rounded up to the nearest whole number.

                (iv) The Exercise Price of all Nonstatutory Options granted to
        an Outside Director under this Section 4(b) shall be equal to 100% of
        the Fair Market Value of a Share on the date of grant, payable in one of
        the forms described in Section 9(a), (b) and (d).


                                      -7-
<PAGE>   13

                (v) Each Option granted under Section 4(b)(ii) shall become
        exercisable (a) one-fourth (1/4) on the first anniversary of the date of
        grant, and (b) one-forty-eighth (1/48) on each of a series of thirty-six
        (36) monthly installments thereafter. Except as set forth in the next
        succeeding sentence, each Option granted under Section 4(b)(iii) above
        shall become exercisable in full on the first anniversary of the date of
        grant. Each Option granted to Outside Directors who were not initially
        elected at a regular annual meeting of the Company's stockholders shall
        become exercisable in full at the next regular annual meeting of the
        Company's stockholders following the date of grant. Notwithstanding the
        foregoing, each Option shall become exercisable in full in the event
        that a Change in Control occurs with respect to the Company.

                (vi) Subject to Sections 4(b)(vii) and (viii), all Nonstatutory
        Options granted to an Outside Director under this Section 4(b) shall
        terminate on the tenth anniversary of the date of grant of such Options.

                (vii) If an Optionee's Service terminates for any reason other
        than death, then his or her Options shall expire on the earliest of the
        following occasions:

                        (A) The expiration date determined pursuant to Section
                4(b)(vi) above;

                        (B) The date 24 months after the termination of the
                Optionee's Service, if the termination occurs because of his or
                her Total and Permanent Disability; or

                        (C) The date six months after the termination of the
                Optionee's Service for any reason other than Total and Permanent
                Disability.

        The Optionee may exercise all or part of his or her Options at any time
        before the expiration of such Options under the preceding sentence, but
        only to the extent that such Options had become exercisable before his
        or her Service terminated. The balance of such Options shall lapse when
        the Optionee's Service terminates. In the event that the Optionee dies
        after the termination of his or her Service but before the expiration of
        his or her Options, all or part of such Options may be exercised at any
        time prior to their expiration by the executors or administrators of the
        Optionee's estate or by any person who has acquired such Options
        directly from him or her by bequest, inheritance or beneficiary
        designation under the Plan, but only to the extent that such Options had
        become exercisable before his or her Service terminated.

                (viii) If an Optionee dies while he or she is in Service, then
        his or her Options shall expire on the earlier of the following dates:

                        (A) The expiration date determined pursuant to Section
                4(b)(vi) above; or

                        (B) The date 24 months after his or her death.


                                      -8-
<PAGE>   14

        All or part of the Optionee's Options may be exercised at any time
        before the expiration of such Options under the preceding sentence by
        the executors or administrators of his or her estate or by any person
        who has acquired such Options directly from him or her by bequest,
        inheritance or beneficiary designation under the Plan.

                (ix) No Option shall be transferable by the Optionee other than
        by will, by written beneficiary designation or by the laws of descent
        and distribution. An Option may be exercised during the lifetime of the
        Optionee only by the Optionee or by the Optionee's guardian or legal
        representative. No Option or interest therein may be transferred,
        assigned, pledged or hypothecated by the Optionee during his or her
        lifetime, whether by operation of law or otherwise, or be made subject
        to execution, attachment or similar process.

        (c) Limitation On Grants. No Employee or Consultant shall be granted
Options to purchase more than one million (1,000,000) Shares in any fiscal year
of the Company, except that Options granted to a new Employee or Consultant in
the fiscal year of the Company in which his or her Service first commences shall
not cover more than two million (2,000,000) Shares (in each case subject to
adjustment in accordance with Section 12).

        (d) Ten-Percent Stockholders. An Employee who owns more than 10% of the
total combined voting power of all classes of outstanding stock of the Company,
a Parent or Subsidiary shall not be eligible for the grant of an ISO unless such
grant satisfies the requirements of Section 422(c)(6) of the Code.

        (e) Attribution Rules. For purposes of Section 4(d) above, in
determining stock ownership, an Employee shall be deemed to own the stock owned,
directly or indirectly, by or for such Employee's brothers, sisters, spouse,
ancestors and lineal descendants. Stock owned, directly or indirectly, by or for
a corporation, partnership, estate or trust shall be deemed to be owned
proportionately by or for its stockholders, partners or beneficiaries.

        (f) Outstanding Stock. For purposes of Section 4(d) above, "outstanding
stock" shall include all stock actually issued and outstanding immediately after
the grant. "Outstanding stock" shall not include shares authorized for issuance
under outstanding options held by the Employee or by any other person.

        SECTION 5. STOCK SUBJECT TO PLAN.

        (a) Basic Limitation. Shares offered under the Plan shall be authorized
but unissued Shares or treasury Shares. The maximum aggregate number of Options,
SARs, Stock Units and Restricted Shares awarded under the Plan shall not exceed
six million (6,000,000) Shares, plus the additional Shares described in Sections
(b) and (c), but in no event more than ten million (10,000,000) Shares. The
limitation of this Section 5(a) shall be subject to adjustment pursuant to
Section 12.

        (b) Annual Increase in Shares. As of January 1 of each year, commencing
with the year 2001, the aggregate number of Options, SARs, Stock Units and
Restricted Shares that may be awarded under the Plan shall automatically
increase by a number equal to the lesser of (i) two


                                      -9-
<PAGE>   15

million five hundred thousand (2,500,000) shares, (ii) four percent (4%) of the
outstanding shares of Stock of the Company on such date or (iii) a lesser amount
determined by the Board. The aggregate number of Shares that may be issued under
the Plan shall at all times be subject to adjustment pursuant to Section 12. The
number of Shares that are subject to Options or other rights outstanding at any
time under the Plan shall not exceed the number of Shares which then remain
available for issuance under the Plan. The Company, during the term of the Plan,
shall at all times reserve and keep available sufficient Shares to satisfy the
requirements of the Plan.

        (c) Additional Shares.

                (i) Upon the expiration or termination unexercised of currently
        outstanding options or the repurchase of restricted shares under the
        Predecessor Plans, the Company shall reserve an equivalent number of
        shares as were initially reserved for issuance pursuant to such expired
        or terminated unexercised options or repurchased shares (together with
        such additional number of shares as may be required pursuant to the
        antidilution provisions of the Predecessor Plans) of its Common Stock,
        subject to adjustment under Section 12, and such shares shall become
        available for Awards under the Plan.

                (ii) If Restricted Shares or Shares issued upon the exercise of
        Options are forfeited, then such Shares shall again become available for
        Awards under the Plan. If Stock Units, Options or SARs are forfeited or
        terminate for any other reason before being exercised, then the
        corresponding Shares shall again become available for Awards under the
        Plan. If Stock Units are settled, then only the number of Shares (if
        any) actually issued in settlement of such Stock Units shall reduce the
        number available under Section 5(a) and the balance shall again become
        available for Awards under the Plan. If SARs are exercised, then only
        the number of Shares (if any) actually issued in settlement of such SARs
        shall reduce the number available in Section 5(a) and the balance shall
        again become available for Awards under the Plan. The foregoing
        notwithstanding, the aggregate number of Shares that may be issued under
        the Plan upon the exercise of ISOs shall not be increased when
        Restricted Shares or other Shares are forfeited.

        (d) Dividend Equivalents. Any dividend equivalents paid or credited
under the Plan shall not be applied against the number of Restricted Shares,
Stock Units, Options or SARs available for Awards, whether or not such dividend
equivalents are converted into Stock Units.

        SECTION 6. RESTRICTED SHARES.

        (a) Restricted Stock Agreement. Each grant of Restricted Shares under
the Plan shall be evidenced by a Restricted Stock Agreement between the
recipient and the Company. Such Restricted Shares shall be subject to all
applicable terms of the Plan and may be subject to any other terms that are not
inconsistent with the Plan. The provisions of the various Restricted Stock
Agreements entered into under the Plan need not be identical.

        (b) Payment for Awards. Subject to the following sentence, Restricted
Shares may be sold or awarded under the Plan for such consideration as the
Committee may determine, including (without limitation) cash, cash equivalents,
full-recourse promissory notes, past services and future services. To the extent
that an Award consists of newly issued Restricted


                                      -10-
<PAGE>   16

Shares, the Award recipient shall furnish consideration with a value not less
than the par value of such Restricted Shares in the form of cash, cash
equivalents, or past services rendered to the Company (or a Parent or
Subsidiary), as the Committee may determine.

        (c) Vesting. Each Award of Restricted Shares may or may not be subject
to vesting. Vesting shall occur, in full or in installments, upon satisfaction
of the conditions specified in the Restricted Stock Agreement. A Restricted
Stock Agreement may provide for accelerated vesting in the event of the
Participant's death, disability or retirement or other events. The Committee may
determine, at the time of granting Restricted Shares of thereafter, that all or
part of such Restricted Shares shall become vested in the event that a Change in
Control occurs with respect to the Company.

        (d) Voting and Dividend Rights. The holders of Restricted Shares awarded
under the Plan shall have the same voting, dividend and other rights as the
Company's other stockholders. A Restricted Stock Agreement, however, may require
that the holders of Restricted Shares invest any cash dividends received in
additional Restricted Shares. Such additional Restricted Shares shall be subject
to the same conditions and restrictions as the Award with respect to which the
dividends were paid.

        SECTION 7. OTHER TERMS AND CONDITIONS OF AWARDS OR SALES.

        (a) Duration of Offers and Nontransferability of Rights. Any right to
acquire Shares under the Plan (other than an Option) shall automatically expire
if not exercised by the Offeree 30 days after the grant of such right was
communicated to him by the Committee. Such right shall not be transferable and
shall be exercisable only by the Offeree to whom such right was granted.

        (b) Purchase Price. The Purchase Price shall be determined by the
Committee at its sole discretion. The Purchase Price shall be payable in one of
the forms described in Sections 9(a), (b), (c), (f) or (g).

        (c) Withholding Taxes. As a condition to the purchase of Shares, the
Offeree shall make such arrangements as the Committee may require for the
satisfaction of any federal, state or local withholding tax obligations that may
arise in connection with such purchase.

        (d) Restrictions on Transfer of Shares. Any Shares awarded or sold under
the Plan shall be subject to such special forfeiture conditions, rights of
repurchase, rights of first refusal and other transfer restrictions as the
Committee may determine. Such restrictions shall be set forth in the applicable
Stock Purchase Agreement and shall apply in addition to any general restrictions
that may apply to all holders of Shares.

        SECTION 8. TERMS AND CONDITIONS OF OPTIONS.

        (a) Stock Option Agreement. Each grant of an Option under the Plan shall
be evidenced by a Stock Option Agreement between the Optionee and the Company.
Such Option shall be subject to all applicable terms and conditions of the Plan
and may be subject to any other terms and conditions which are not inconsistent
with the Plan and which the Committee deems appropriate for inclusion in a Stock
Option Agreement. The Stock Option Agreement shall


                                      -11-

<PAGE>   17

specify whether the Option is an ISO or an NSO. The provisions of the various
Stock Option Agreements entered into under the Plan need not be identical.
Options may be granted in consideration of a reduction in the Optionee's other
compensation. A Stock Option Agreement may provide that a new Option will be
granted automatically to the Optionee when he or she exercises a prior Option
and pays the Exercise Price in a form described in Section 9.

        (b) Number of Shares. Each Stock Option Agreement shall specify the
number of Shares that are subject to the Option and shall provide for the
adjustment of such number in accordance with Section 12. Options granted to an
Optionee in a single fiscal year of the Company shall not cover more than one
million (1,000,000) Shares, except that Options granted to a new Employee or
Consultant in the fiscal year of the Company in which his or her Service first
commences shall not cover more than two million (2,000,000) Shares (in each case
subject to adjustment in accordance with Section 12).

        (c) Exercise Price. Each Stock Option Agreement shall specify the
Exercise Price. The Exercise Price of an ISO shall not be less than 100% of the
Fair Market Value of a Share on the date of grant, except as otherwise provided
in Section 4(d), and the Exercise Price of an NSO shall not be less than the par
value of the Shares subject to such NSO. Subject to the foregoing in this
Section 8(c), the Exercise Price under any Option shall be determined by the
Committee at its sole discretion. The Exercise Price shall be payable in one of
the forms described in Section 9.

        (d) Withholding Taxes. As a condition to the exercise of an Option, the
Optionee shall make such arrangements as the Committee may require for the
satisfaction of any federal, state or local withholding tax obligations that may
arise in connection with such exercise. The Optionee shall also make such
arrangements as the Committee may require for the satisfaction of any federal,
state or local withholding tax obligations that may arise in connection with the
disposition of Shares acquired by exercising an Option.

        (e) Exercisability and Term. Each Stock Option Agreement shall specify
the date when all or any installment of the Option is to become exercisable. The
Stock Option Agreement shall also specify the term of the Option; provided that
the term of an ISO shall in no event exceed 10 years from the date of grant
(five years for Employees described in Section 4(d)). A Stock Option Agreement
may provide for accelerated exercisability in the event of the Optionee's death,
disability, or retirement or other events and may provide for expiration prior
to the end of its term in the event of the termination of the Optionee's
service. Options may be awarded in combination with SARs, and such an Award may
provide that the Options will not be exercisable unless the related SARs are
forfeited. Subject to the foregoing in this Section 8(e), the Committee at its
sole discretion shall determine when all or any installment of an Option is to
become exercisable and when an Option is to expire.

        (f) Nontransferability. During an Optionee's lifetime, his or her
Option(s) shall be exercisable only by the Optionee and shall not be
transferable. In the event of an Optionee's death, his or her Option(s) shall
not be transferable other than by will or by the laws of descent and
distribution.


                                      -12-
<PAGE>   18

        (g) Exercise of Options Upon Termination of Service. Each Stock Option
Agreement shall set forth the extent to which the Optionee shall have the right
to exercise the Option following termination of the Optionee's Service with the
Company and its Subsidiaries, and the right to exercise the Option of any
executors or administrators of the Optionee's estate or any person who has
acquired such Option(s) directly from the Optionee by bequest or inheritance.
Such provisions shall be determined in the sole discretion of the Committee,
need not be uniform among all Options issued pursuant to the Plan, and may
reflect distinctions based on the reasons for termination of Service.

        (h) Effect of Change in Control. The Committee may determine, at the
time of granting an Option or thereafter, that such Option shall become
exercisable as to all or part of the Shares subject to such Option in the event
that a Change in Control occurs with respect to the Company, subject to the
following limitations:

                (i) In the case of an ISO, the acceleration of exercisability
        shall not occur without the Optionee's written consent.

                (ii) If the Company and the other party to the transaction
        constituting a Change in Control agree that such transaction is to be
        treated as a "pooling of interests" for financial reporting purposes,
        and if such transaction in fact is so treated, then the acceleration of
        exercisability shall not occur to the extent that the Company's
        independent accountants and such other party's independent accountants
        separately determine in good faith that such acceleration would preclude
        the use of "pooling of interests" accounting.

        (i) Leaves of Absence. An Employee's Service shall cease when such
Employee ceases to be actively employed by, or a consultant or adviser to, the
Company (or any subsidiary) as determined in the sole discretion of the Board of
Directors. For purposes of Options, Service does not terminate when an Employee
goes on a bona fide leave of absence, that was approved by the Company in
writing, if the terms of the leave provide for continued service crediting, or
when continued service crediting is required by applicable law. However, for
purposes of determining whether an Option is entitled to ISO status, an
Employee's Service will be treated as terminating 90 days after such Employee
went on leave, unless such Employee's right to return to active work is
guaranteed by law or by a contract. Service terminates in any event when the
approved leave ends, unless such Employee immediately returns to active work.
The Company determines which leaves count toward Service, and when Service
terminates for all purposes under the Plan.

        (j) No Rights as a Stockholder. An Optionee, or a transferee of an
Optionee, shall have no rights as a stockholder with respect to any Shares
covered by his Option until the date of the issuance of a stock certificate for
such Shares. No adjustments shall be made, except as provided in Section 12.

        (k) Modification, Extension and Renewal of Options. Within the
limitations of the Plan, the Committee may modify, extend or renew outstanding
options or may accept the cancellation of outstanding options (to the extent not
previously exercised), whether or not granted hereunder, in return for the grant
of new Options for the same or a different number of Shares


                                      -13-
<PAGE>   19

and at the same or a different exercise price. The foregoing notwithstanding, no
modification of an Option shall, without the consent of the Optionee, alter or
impair his or her rights or obligations under such Option.

        (l) Restrictions on Transfer of Shares. Any Shares issued upon exercise
of an Option shall be subject to such special forfeiture conditions, rights of
repurchase, rights of first refusal and other transfer restrictions as the
Committee may determine. Such restrictions shall be set forth in the applicable
Stock Option Agreement and shall apply in addition to any general restrictions
that may apply to all holders of Shares.

        (m) Buyout Provisions. The Committee may at any time (a) offer to buy
out for a payment in cash or cash equivalents an Option previously granted or
(b) authorize an Optionee to elect to cash out an Option previously granted, in
either case at such time and based upon such terms and conditions as the
Committee shall establish.

        SECTION 9. PAYMENT FOR SHARES.

        (a) General Rule. The entire Exercise Price of Shares issued under the
Plan shall be payable in lawful money of the United States of America at the
time when such Shares are purchased, except as provided in Sections 9(b) through
9(g) below.

        (b) Surrender of Stock. To the extent that a Stock Option Agreement so
provides, payment may be made all or in part by surrendering, or attesting to
the ownership of, Shares which have already been owned by the Optionee or his
representative for more than 12 months. Such Shares shall be valued at their
Fair Market Value on the date when the new Shares are purchased under the Plan.
The Optionee shall not surrender, or attest to the ownership of, Shares in
payment of the Exercise Price if such action would cause the Company to
recognize compensation expense (or additional compensation expense) with respect
to the Option for financial reporting purposes.

        (c) Services Rendered. At the discretion of the Committee, Shares may be
awarded under the Plan in consideration of services rendered to the Company or a
Subsidiary prior to the award. If Shares are awarded without the payment of a
Purchase Price in cash, the Committee shall make a determination (at the time of
the award) of the value of the services rendered by the Offeree and the
sufficiency of the consideration to meet the requirements of Section 6(c).

        (d) Cashless Exercise. To the extent that a Stock Option Agreement so
provides, payment may be made all or in part by delivery (on a form prescribed
by the Committee) of an irrevocable direction to a securities broker to sell
Shares and to deliver all or part of the sale proceeds to the Company in payment
of the aggregate Exercise Price.

        (e) Exercise/Pledge. To the extent that a Stock Option Agreement so
provides, payment may be made all or in part by delivery (on a form prescribed
by the Committee) of an irrevocable direction to a securities broker or lender
to pledge Shares, as security for a loan, and to deliver all or part of the loan
proceeds to the Company in payment of the aggregate Exercise Price.


                                      -14-
<PAGE>   20

        (f) Promissory Note. To the extent that a Stock Option Agreement so
provides, payment may be made all or in part by delivering (on a form prescribed
by the Company) a full-recourse promissory note. However, the par value of the
Common Shares being purchased under the Plan, if newly issued, shall be paid in
cash or cash equivalents.

        (g) Other Forms of Payment. To the extent that a Stock Option Agreement
so provides, payment may be made in any other form that is consistent with
applicable laws, regulations and rules.

        SECTION 10. STOCK APPRECIATION RIGHTS.

        (a) SAR Agreement. Each grant of a SAR under the Plan shall be evidenced
by a SAR Agreement between the Optionee and the Company. Such SAR shall be
subject to all applicable terms of the Plan and may be subject to any other
terms that are not inconsistent with the Plan. The provisions of the various SAR
Agreements entered into under the Plan need not be identical. SARs may be
granted in consideration of a reduction in the Optionee's other compensation.

        (b) Number of Shares. Each SAR Agreement shall specify the number of
Shares to which the SAR pertains and shall provide for the adjustment of such
number in accordance with Section 12. SARs granted to any Optionee in a single
calendar year shall in no event pertain to more than one million (1,000,000)
Shares. The limitation set forth in the preceding sentence shall be subject to
adjustment in accordance with Section 12.

        (c) Exercise Price. Each SAR Agreement shall specify the Exercise Price.
A SAR Agreement may specify an Exercise Price that varies in accordance with a
predetermined formula while the SAR is outstanding.

        (d) Exercisability and Term. Each SAR Agreement shall specify the date
when all or any installment of the SAR is to become exercisable. The SAR
Agreement shall also specify the term of the SAR. A SAR Agreement may provide
for accelerated exercisability in the event of the Optionee's death, disability
or retirement or other events and may provide for expiration prior to the end of
its term in the event of the termination of the Optionee's service. SARs may be
awarded in combination with Options, and such an Award may provide that the SARs
will not be exercisable unless the related Options are forfeited. A SAR may be
included in an ISO only at the time of grant but may be included in an NSO at
the time of grant or thereafter. A SAR granted under the Plan may provide that
it will be exercisable only in the event of a Change in Control.

        (e) Effect of Change in Control. The Committee may determine, at the
time of granting a SAR or thereafter, that such SAR shall become fully
exercisable as to all Common Shares subject to such SAR in the event that a
Change in Control occurs with respect to the Company, subject to the following
sentence. If the Company and the other party to the transaction constituting a
Change in Control agree that such transaction is to be treated as a "pooling of
interests" for financial reporting purposes, and if such transaction in fact is
so treated, then the acceleration of exercisability shall not occur to the
extent that the Company's


                                      -15-
<PAGE>   21

independent accountants and such other party's independent accountants
separately determine in good faith that such acceleration would preclude the use
of "pooling of interests" accounting.

        (f) Exercise of SARs. If, on the date when a SAR expires, the Exercise
Price under such SAR is less than the Fair Market Value on such date but any
portion of such SAR has not been exercised or surrendered, then such SAR shall
automatically be deemed to be exercised as of such date with respect to such
portion. Upon exercise of a SAR, the Optionee (or any person having the right to
exercise the SAR after his or her death) shall receive from the Company (a)
Shares, (b) cash or (c) a combination of Shares and cash, as the Committee shall
determine. The amount of cash and/or the Fair Market Value of Shares received
upon exercise of SARs shall, in the aggregate, be equal to the amount by which
the Fair Market Value (on the date of surrender) of the Shares subject to the
SARs exceeds the Exercise Price.

        (g) Special Holding Period. To the extent required by Section 16 of the
Exchange Act or any rule thereunder, an SAR shall not be exercised for cash
unless both it and the related Option have been outstanding for more than six
months.

        (h) Special Exercise Window. To the extent required by Section 16 of the
Exchange Act or any rule thereunder, an SAR may only be exercised for cash
during a period which (a) begins on the third business day following a date when
the Company's quarterly summary statement of sales and earnings is released to
the public and (b) ends on the third business day following such date. This
Section 10(h) shall not apply if the exercise occurs automatically on the date
when the related Option expires, and the Committee may determine that it shall
not apply to limited SARs that are exercisable only in the event of a Change in
Control.

        (i) Modification or Assumption of SARs. Within the limitations of the
Plan, the Committee may modify, extend or assume outstanding SARs or may accept
the cancellation of outstanding SARs (whether granted by the Company or by
another issuer) in return for the grant of new SARs for the same or a different
number of shares and at the same or a different exercise price. The foregoing
notwithstanding, no modification of a SAR shall, without the consent of the
Optionee, may alter or impair his or her rights or obligations under such SAR.

        SECTION 11. STOCK UNITS.

        (a) Stock Unit Agreement. Each grant of Stock Units under the Plan shall
be evidenced by a Stock Unit Agreement between the recipient and the Company.
Such Stock Units shall be subject to all applicable terms of the Plan and may be
subject to any other terms that are not inconsistent with the Plan. The
provisions of the various Stock Unit Agreements entered into under the Plan need
not be identical. Stock Units may be granted in consideration of a reduction in
the recipient's other compensation.

        (b) Payment for Awards. To the extent that an Award is granted in the
form of Stock Units, no cash consideration shall be required of the Award
recipients.

        (c) Vesting Conditions. Each Award of Stock Units may or may not be
subject to vesting. Vesting shall occur, in full or in installments, upon
satisfaction of the conditions specified in the Stock Unit Agreement. A Stock
Unit Agreement may provide for accelerated vesting in the event of the
Participant's death, disability or retirement or other events. The


                                      -16-
<PAGE>   22

Committee may determine, at the time of granting Stock Units or thereafter, that
all or part of such Stock Units shall become vested in the event that a Change
in Control occurs with respect to the Company, except as provided in the next
following sentence. If the Company and the other party to the transaction
constituting a Change in Control agree that such transaction is to be treated as
a "pooling of interests" for financial reporting purposes, and if such
transaction in fact is so treated, then the acceleration of vesting shall not
occur to the extent that the Company's independent accountants and such other
party's independent accountants separately determine in good faith that such
acceleration would preclude the use of "pooling of interests" accounting.

        (d) Voting and Dividend Rights. The holders of Stock Units shall have no
voting rights. Prior to settlement or forfeiture, any Stock Unit awarded under
the Plan may, at the Committee's discretion, carry with it a right to dividend
equivalents. Such right entitles the holder to be credited with an amount equal
to all cash dividends paid on one Share while the Stock Unit is outstanding.
Dividend equivalents may be converted into additional Stock Units. Settlement of
dividend equivalents may be made in the form of cash, in the form of Shares, or
in a combination of both. Prior to distribution, any dividend equivalents which
are not paid shall be subject to the same conditions and restrictions (including
without limitation, any forfeiture conditions) as the Stock Units to which they
attach.

        (e) Form and Time of Settlement of Stock Units. Settlement of vested
Stock Units may be made in the form of (a) cash, (b) Shares or (c) any
combination of both, as determined by the Committee. The actual number of Stock
Units eligible for settlement may be larger or smaller than the number included
in the original Award, based on predetermined performance factors. Methods of
converting Stock Units into cash may include (without limitation) a method based
on the average Fair Market Value of Shares over a series of trading days. Vested
Stock Units may be settled in a lump sum or in installments. The distribution
may occur or commence when all vesting conditions applicable to the Stock Units
have been satisfied or have lapsed, or it may be deferred to any later date. The
amount of a deferred distribution may be increased by an interest factor or by
dividend equivalents. Until an Award of Stock Units is settled, the number of
such Stock Units shall be subject to adjustment pursuant to Section 12.

        (f) Death of Recipient. Any Stock Units Award that becomes payable after
the recipient's death shall be distributed to the recipient's beneficiary or
beneficiaries. Each recipient of a Stock Units Award under the Plan shall
designate one or more beneficiaries for this purpose by filing the prescribed
form with the Company. A beneficiary designation may be changed by filing the
prescribed form with the Company at any time before the Award recipient's death.
If no beneficiary was designated or if no designated beneficiary survives the
Award recipient, then any Stock Units Award that becomes payable after the
recipient's death shall be distributed to the recipient's estate.

        (g) Creditors' Rights. A holder of Stock Units shall have no rights
other than those of a general creditor of the Company. Stock Units represent an
unfunded and unsecured obligation of the Company, subject to the terms and
conditions of the applicable Stock Unit Agreement.

        SECTION 12. ADJUSTMENT OF SHARES.

        (a) Adjustments. In the event of a subdivision of the outstanding Stock,
a declaration of a dividend payable in Shares, a declaration of a dividend
payable in a form other than Shares in an amount that has a material effect on
the price of Shares, a combination or consolidation of the outstanding Stock (by
reclassification or otherwise) into a lesser number of Shares, a
recapitalization, a spin-off or a similar occurrence, the Committee shall make
such adjustments as it, in its sole discretion, deems appropriate in one or more
of:

                (i) The number of Options, SARs, Restricted Shares and Stock
        Units available for future Awards under Section 5;

                (ii) The limitations set forth in Sections 4(c), 8(b) and 10(b);

                (iii) The number of NSOs to be granted to Outside Directors
        under Section 4(b);

                (iv) The number of Shares covered by each outstanding Option and
        SAR;

                (v) The Exercise Price under each outstanding Option and SAR; or

                (vi) The number of Stock Units included in any prior Award which
        has not yet been settled.

Except as provided in this Section 12, a Participant shall have no rights by
reason of any issue by the Company of stock of any class or securities
convertible into stock of any class, any subdivision or consolidation of shares
of stock of any class, the payment of any stock dividend or any other increase
or decrease in the number of shares of stock of any class.

        (b) Dissolution or Liquidation. To the extent not previously exercised
or settled, Options, SARs and Stock Units shall terminate immediately prior to
the dissolution or liquidation of the Company.

        (c) Reorganizations. In the event that the Company is a party to a
merger or other reorganization, outstanding Awards shall be subject to the
agreement of merger or reorganization. Such agreement shall provide for:

                (i) The continuation of the outstanding Awards by the Company,
        if the Company is a surviving corporation;

                (ii) The assumption of the outstanding Awards by the surviving
        corporation or its parent or subsidiary;

                (iii) The substitution by the surviving corporation or its
        parent or subsidiary of its own awards for the outstanding Awards;

                (iv) Full exercisability or vesting and accelerated expiration
        of the outstanding Awards; or


                                      -18-
<PAGE>   24

                (v) Settlement of the full value of the outstanding Awards in
        cash or cash equivalents followed by cancellation of such Awards.

        (d) Reservation of Rights. Except as provided in this Section 12, an
Optionee or Offeree shall have no rights by reason of any subdivision or
consolidation of shares of stock of any class, the payment of any dividend or
any other increase or decrease in the number of shares of stock of any class.
Any issue by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall not affect, and no
adjustment by reason thereof shall be made with respect to, the number or
Exercise Price of Shares subject to an Option. The grant of an Option pursuant
to the Plan shall not affect in any way the right or power of the Company to
make adjustments, reclassifications, reorganizations or changes of its capital
or business structure, to merge or consolidate or to dissolve, liquidate, sell
or transfer all or any part of its business or assets.

        SECTION 13. DEFERRAL OF AWARDS.

        The Committee (in its sole discretion) may permit or require a
Participant to:

        (a) Have cash that otherwise would be paid to such Participant as a
            result of the exercise of a SAR or the settlement of Stock Units
            credited to a deferred compensation account established for such
            Participant by the Committee as an entry on the Company's books;

        (b) Have Shares that otherwise would be delivered to such Participant as
            a result of the exercise of an Option or SAR converted into an equal
            number of Stock Units; or

        (c) Have Shares that otherwise would be delivered to such Participant as
            a result of the exercise of an Option or SAR or the settlement of
            Stock Units converted into amounts credited to a deferred
            compensation account established for such Participant by the
            Committee as an entry on the Company's books. Such amounts shall be
            determined by reference to the Fair Market Value of such Shares as
            of the date when they otherwise would have been delivered to such
            Participant.

A deferred compensation account established under this Section 13 may be
credited with interest or other forms of investment return, as determined by the
Committee. A Participant for whom such an account is established shall have no
rights other than those of a general creditor of the Company. Such an account
shall represent an unfunded and unsecured obligation of the Company and shall be
subject to the terms and conditions of the applicable agreement between such
Participant and the Company. If the deferral or conversion of Awards is
permitted or required, the Committee (in its sole discretion) may establish
rules, procedures and forms pertaining to such Awards, including (without
limitation) the settlement of deferred compensation accounts established under
this Section 13.

        SECTION 14. AWARDS UNDER OTHER PLANS.

The Company may grant awards under other plans or programs. Such awards may be
settled in the form of Shares issued under this Plan. Such Shares shall be
treated for all purposes


                                      -19-
<PAGE>   25

under the Plan like Shares issued in settlement of Stock Units and shall, when
issued, reduce the number of Shares available under Section 5.

        SECTION 15. PAYMENT OF DIRECTOR'S FEES IN SECURITIES.

        (a) Effective Date. No provision of this Section 15 shall be effective
unless and until the Board has determined to implement such provision.

        (b) Elections to Receive NSOs, Restricted Shares or Stock Units. An
Outside Director may elect to receive his or her annual retainer payments and/or
meeting fees from the Company in the form of cash, NSOs, Restricted Shares or
Stock Units, or a combination thereof, as determined by the Board. Such NSOs,
Restricted Shares and Stock Units shall be issued under the Plan. An election
under this Section 15 shall be filed with the Company on the prescribed form.

        (c) Number and Terms of NSOs, Restricted Shares or Stock Units. The
number of NSOs, Restricted Shares or Stock Units to be granted to Outside
Directors in lieu of annual retainers and meeting fees that would otherwise be
paid in cash shall be calculated in a manner determined by the Board. The terms
of such NSOs, Restricted Shares or Stock Units shall also be determined by the
Board.

        SECTION 16. LEGAL AND REGULATORY REQUIREMENTS.

        Shares shall not be issued under the Plan unless the issuance and
delivery of such Shares complies with (or is exempt from) all applicable
requirements of law, including (without limitation) the Securities Act of 1933,
as amended, the rules and regulations promulgated thereunder, state securities
laws and regulations and the regulations of any stock exchange on which the
Company's securities may then be listed, and the Company has obtained the
approval or favorable ruling from any governmental agency which the Company
determines is necessary or advisable.

        SECTION 17. WITHHOLDING TAXES.

        (a) General. To the extent required by applicable federal, state, local
or foreign law, a Participant or his or her successor shall make arrangements
satisfactory to the Company for the satisfaction of any withholding tax
obligations that arise in connection with the Plan. The Company shall not be
required to issue any Shares or make any cash payment under the Plan until such
obligations are satisfied.

        (b) Share Withholding. The Committee may permit a Participant to satisfy
all or part of his or her withholding or income tax obligations by having the
Company withhold all or a portion of any Shares that otherwise would be issued
to him or her or by surrendering all or a portion of any Shares that he or she
previously acquired. Such Shares shall be valued at their Fair Market Value on
the date when taxes otherwise would be withheld in cash, and the value of the
Shares shall not exceed the amount of the withholding or income tax obligations.


                                      -20-
<PAGE>   26

        SECTION 18. LIMITATION ON PARACHUTE PAYMENTS.

        (a) Scope of Limitation. This Section 18 shall apply to an Award unless
the Committee, at the time of making an Award under the Plan or at any time
thereafter, specifies in writing that such Award shall not be subject to this
Section 18. If this Section 18 applies to an Award, it shall supersede any
contrary provision of the Plan or of any Award granted under the Plan.

        (b) Basic Rule. In the event that the independent auditors most recently
selected by the Board (the "Auditors") determine that any payment or transfer by
the Company under the Plan to or for the benefit of a Participant (a "Payment")
would be nondeductible by the Company for federal income tax purposes because of
the provisions concerning "excess parachute payments" in Section 280G of the
Code, then the aggregate present value of all Payments shall be reduced (but not
below zero) to the Reduced Amount. For purposes of this Section 18, the "Reduced
Amount" shall be the amount, expressed as a present value, which maximizes the
aggregate present value of the Payments without causing any Payment to be
nondeductible by the Company because of Section 280G of the Code.

        (c) Reduction of Payments. If the Auditors determine that any Payment
would be nondeductible by the Company because of Section 280G of the Code, then
the Company shall promptly give the Participant notice to that effect and a copy
of the detailed calculation thereof and of the Reduced Amount, and the
Participant may then elect, in his or her sole discretion, which and how much of
the Payments shall be eliminated or reduced (as long as after such election the
aggregate present value of the Payments equals the Reduced Amount) and shall
advise the Company in writing of his or her election within 10 days of receipt
of notice. If no such election is made by the Participant within such 10-day
period, then the Company may elect which and how much of the Payments shall be
eliminated or reduced (as long as after such election the aggregate present
value of the Payments equals the Reduced Amount) and shall notify the
Participant promptly of such election. For purposes of this Section 18, present
value shall be determined in accordance with Section 280G(d)(4) of the Code. All
determinations made by the Auditors under this Section 18 shall be binding upon
the Company and the Participant and shall be made within 60 days of the date
when a Payment becomes payable or transferable. As promptly as practicable
following such determination and the elections hereunder, the Company shall pay
or transfer to or for the benefit of the Participant such amounts as are then
due to him or her under the Plan and shall promptly pay or transfer to or for
the benefit of the Participant in the future such amounts as become due to him
or her under the Plan.

        (d) Overpayments and Underpayments. As a result of uncertainty in the
application of Section 280G of the Code at the time of an initial determination
by the Auditors hereunder, it is possible that Payments will have been made by
the Company that should not have been made (an "Overpayment") or that additional
Payments that will not have been made by the Company could have been made (an
"Underpayment"), consistent in each case with the calculation of the Reduced
Amount hereunder. In the event that the Auditors, based upon the assertion of a
deficiency by the Internal Revenue Service against the Company or the
Participant that the Auditors believe has a high probability of success,
determine that an Overpayment has been made, such Overpayment shall be treated
for all purposes as a loan to the Participant which he or she shall repay to the
Company, together with interest at the applicable federal rate provided in


                                      -21-
<PAGE>   27

Section 7872(f)(2) of the Code; provided, however, that no amount shall be
payable by the Participant to the Company if and to the extent that such payment
would not reduce the amount subject to taxation under Section 4999 of the Code.
In the event that the Auditors determine that an Underpayment has occurred, such
Underpayment shall promptly be paid or transferred by the Company to or for the
benefit of the Participant, together with interest at the applicable federal
rate provided in Section 7872(f)(2) of the Code.

        (e) Related Corporations. For purposes of this Section 18, the term
"Company" shall include affiliated corporations to the extent determined by the
Auditors in accordance with Section 280G(d)(5) of the Code.

        SECTION 19. NO EMPLOYMENT RIGHTS.

        No provision of the Plan, nor any right or Option granted under the
Plan, shall be construed to give any person any right to become, to be treated
as, or to remain an Employee. The Company and its Subsidiaries reserve the right
to terminate any person's Service at any time and for any reason, with or
without notice.

        SECTION 20. DURATION AND AMENDMENTS.

        (a) Term of the Plan. The Plan, as set forth herein, shall terminate
automatically on July 10, 2010 and may be terminated on any earlier date
pursuant to Subsection (b) below.

        (b) Predecessor Plans. The Plan shall serve as the successor to the
Predecessor Plans, and no further option grants shall be made under the
Predecessor Plans after the Plan's effective date. All options outstanding under
the Predecessor Plans as of the Plan's effective date shall, immediately upon
approval of the Plan by the Company's stockholders, be incorporated into the
Plan and treated as outstanding options under the Plan. However, each
outstanding option so incorporated shall continue to be governed solely by the
terms of the documents evidencing such option, and no provision of the Plan
shall be deemed to affect or otherwise modify the rights or obligations of the
holders of such incorporated options with respect to their acquisition of shares
of Stock.

        (c) Right to Amend or Terminate the Plan. The Board of Directors may
amend the Plan at any time and from time to time. Rights and obligations under
any Option granted before amendment of the Plan shall not be materially impaired
by such amendment, except with consent of the person to whom the Option was
granted. An amendment of the Plan shall be subject to the approval of the
Company's stockholders only to the extent required by applicable laws,
regulations or rules.

        (d) Effect of Amendment or Termination. No Shares shall be issued or
sold under the Plan after the termination thereof, except upon exercise of an
Option granted prior to such termination. The termination of the Plan, or any
amendment thereof, shall not affect any Share previously issued or any Option
previously granted under the Plan.

        SECTION 21. EXECUTION.

        To record the adoption of the Plan by the Board of Directors effective

its authorized officer to execute the same.
