<Page>

for the benefit of the Company or of an Affiliate and to provide additional
incentive for them to promote the success of the Company or of an Affiliate. The
Plan provides for the granting of ISOs, Non-Qualified Options, Stock Grants and
Stock-Based Awards.

3.       SHARES SUBJECT TO THE PLAN.

       (a) The number of Shares which may be issued from time to time pursuant
to this Plan, shall be 2,500,000, or the equivalent of such number of Shares
after the Administrator, in its sole discretion, has interpreted the effect of
any stock split, stock dividend, combination, recapitalization or similar
transaction in accordance with Paragraph 24 of the Plan.

       (b) Notwithstanding Subparagraph (a) above, on the first day of each
fiscal year of the Company during the period beginning in fiscal year 2008, and
ending on the second day of fiscal year 2016, the number of Shares that may be
issued from time to time pursuant to the Plan, shall be increased by an amount
equal to the lesser of (i) 1,300,000 or the equivalent of such number of Shares
after the Administrator, in its sole discretion, has interpreted the effect of
any stock split, stock dividend, combination, recapitalization or similar
transaction in accordance with Paragraph 24 of the Plan; (ii) 5% of the number
of outstanding shares of Common Stock on such date; and (iii) an amount
determined by the Board. However, in no event shall the number of Shares
available for issuance under this Plan be increased as set forth in this
Subparagraph (c) to the extent such increase, in addition to any other increases
proposed by the Board in the number of shares of Common Stock available for
issuance under all other employee or director stock plans, including, without
limitation, employee stock purchase plans, would result in the total number of
shares of Common Stock then available for issuance under all employee and
director stock plans exceeding 25% of the outstanding shares of the Company on
the first day of the applicable fiscal year.

       (c) If an Option ceases to be outstanding, in whole or in part (other
than by exercise), or if the Company shall reacquire (at not more than its
original issuance price) any Shares issued pursuant to a Stock Grant or
Stock-Based Award, or if any Stock Right expires or is forfeited, cancelled, or
otherwise terminated or results in any Shares not being issued, the unissued
Shares which were subject to such Stock Right shall again be available for
issuance from time to time pursuant to this Plan. Notwithstanding the foregoing,
if a Stock Right is exercised, in whole or in part, by tender of Shares or if
the Company's tax withholding obligation is satisfied by withholding Shares, the
number of Shares deemed to have been issued under the Plan for purposes of the
limitation set forth in Paragraph 3(a) above shall be the number of Shares that
were subject to the Stock Right or portion thereof, and not the net number of
Shares actually issued.

                                       4

4.     ADMINISTRATION OF THE PLAN.

       The Administrator of the Plan will be the Board of Directors, except to
the extent the Board of Directors delegates its authority to the Committee, in
which case the Committee shall be the Administrator. Subject to the provisions
of the Plan, the Administrator is authorized to:

       a.   Interpret the provisions of the Plan and all Stock Rights and to
            make all rules and determinations which it deems necessary or
            advisable for the administration of the Plan;

       b.   Determine which Employees, directors and consultants shall be
            granted Stock Rights;

       c.   Determine the number of Shares for which a Stock Right or Stock
            Rights shall be granted; provided, however, that in no event shall
            Stock Rights with respect to more than 125,000 Shares be granted to
            any Participant in any fiscal year;

       d.   Specify the terms and conditions upon which a Stock Right or Stock
            Rights may be granted;

       e.   Make changes to any outstanding Stock Right, including, without
            limitation, to reduce or increase the exercise price or purchase
            price, to accelerate the vesting schedule or extend the expiration
            date, provided that no such change shall impair the rights of a
            Participant under any grant previously made without such
            Participant's consent;

       f.   Buy out for a payment in cash or Shares, a Stock Right previously
            granted and/or cancel any such Stock Right and grant in substitution
            therefor other Stock Rights, covering the same or a different number
            of Shares and having an exercise price or purchase price per share
            which may be lower or higher than the exercise price or purchase
            price of the cancelled Stock Right, based on such terms and
            conditions as the Administrator shall establish and the Participant
            shall accept; and

       g.   Adopt any sub-plans applicable to residents of any specified
            jurisdiction as it deems necessary or appropriate in order to comply
            with or take advantage of any tax or other laws applicable to the
            Company or to Plan Participants or to otherwise facilitate the
            administration of the Plan, which sub-plans may include additional
            restrictions or conditions applicable to Stock Rights or Shares
            issuable pursuant to a Stock Right;

provided, however, that all such interpretations, rules, determinations, terms
and conditions shall be made and prescribed in the context of preserving the tax
status under Section 422 of the Code of those Options which are designated as
ISOs. Subject to the foregoing, the interpretation and construction by the
Administrator of any provisions of the Plan or of any Stock Right granted under
it shall be final, unless otherwise determined by the Board of Directors, if the
Administrator is the Committee. In addition, if the Administrator is the
Committee, the Board of

                                       5
<Page>

Directors may take any action under the Plan that would otherwise be the
responsibility of the Committee.

       To the extent permitted under applicable law, the Board of Directors or
the Committee may allocate all or any portion of its responsibilities and powers
to any one or more of its members and may delegate all or any portion of its
responsibilities and powers to any other person selected by it. Any such
allocation or delegation may be revoked by the Board of Directors or the
Committee at any time.

5.     ELIGIBILITY FOR PARTICIPATION.

       The Administrator will, in its sole discretion, name the Participants in
the Plan, provided, however, that each Participant must be an Employee, director
or consultant of the Company or of an Affiliate at the time a Stock Right is
granted. Notwithstanding the foregoing, the Administrator may authorize the
grant of a Stock Right to a person not then an Employee, director or consultant
of the Company or of an Affiliate; provided, however, that the actual grant of
such Stock Right shall be conditioned upon such person becoming eligible to
become a Participant at or prior to the time of the execution of the Agreement
evidencing such Stock Right. ISOs may be granted only to Employees.
Non-Qualified Options, Stock Grants and Stock-Based Awards may be granted to any
Employee, director or consultant of the Company or an Affiliate. The granting of
any Stock Right to any individual shall neither entitle that individual to, nor
disqualify him or her from, participation in any other grant of Stock Rights.

6.     TERMS AND CONDITIONS OF OPTIONS.

       Each Option shall be set forth in writing in an Option Agreement, duly
executed by the Company and, to the extent required by law or requested by the
Company, by the Participant. The Administrator may provide that Options be
granted subject to such terms and conditions, consistent with the terms and
conditions specifically required under this Plan, as the Administrator may deem
appropriate including, without limitation, subsequent approval by the
shareholders of the Company of this Plan or any amendments thereto. The Option
Agreements shall be subject to at least the following terms and conditions:

       A.   NON-QUALIFIED OPTIONS: Each Option intended to be a Non-Qualified
            Option shall be subject to the terms and conditions which the
            Administrator determines to be appropriate and in the best interest
            of the Company, subject to the following minimum standards for any
            such Non-Qualified Option:

            a.     OPTION PRICE: Each Option Agreement shall state the option
                   price (per share) of the Shares covered by each Option, which
                   option price shall be determined by the Administrator but
                   shall not be less than the Fair Market Value per share of
                   Common Stock.

                                       6
<Page>

            b.     NUMBER OF SHARES: Each Option Agreement shall state the
                   number of Shares to which it pertains.

            c.     OPTION PERIODS: Each Option Agreement shall state the date or
                   dates on which it first is exercisable and the date after
                   which it may no longer be exercised, and may provide that the
                   Option rights accrue or become exercisable in installments
                   over a period of months or years, or upon the occurrence of
                   certain conditions or the attainment of stated goals or
                   events.

            d.     OPTION CONDITIONS: Exercise of any Option may be conditioned
                   upon the Participant's execution of a Share purchase
                   agreement in form satisfactory to the Administrator providing
                   for certain protections for the Company and its other
                   shareholders, including requirements that:

                   i.     The Participant's or the Participant's Survivors'
                          right to sell or transfer the Shares may be
                          restricted; and

                   ii.    The Participant or the Participant's Survivors may be
                          required to execute letters of investment intent and
                          must also acknowledge that the Shares will bear
                          legends noting any applicable restrictions.

       B.   ISOs: Each Option intended to be an ISO shall be issued only to an
            Employee and be subject to the following terms and conditions, with
            such additional restrictions or changes as the Administrator
            determines are appropriate but not in conflict with Section 422 of
            the Code and relevant regulations and rulings of the Internal
            Revenue Service:

            a.     MINIMUM STANDARDS: The ISO shall meet the minimum standards
                   required of Non-Qualified Options, as described in Paragraph
                   6(A) above.

            b.     OPTION PRICE: Immediately before the ISO is granted, if the
                   Participant owns, directly or by reason of the applicable
                   attribution rules in Section 424(d) of the Code:

                   i.     Ten percent (10%) OR LESS of the total combined voting
                          power of all classes of stock of the Company or an
                          Affiliate, the Option price per share of the Shares
                          covered by each ISO shall not be less than one hundred
                          percent (100%) of the Fair Market Value per share of
                          the Shares on the date of the grant of the Option; or

                   ii.    More than ten percent (10%) of the total combined
                          voting power of all classes of stock of the Company or
                          an Affiliate, the Option price per share of the Shares
                          covered by each ISO shall not be less than one hundred
                          ten percent (110%) of the Fair Market Value on the
                          date of grant.

                                       7
<Page>

            c.     TERM OF OPTION: For Participants who own:

                   i.     Ten percent (10%) OR LESS of the total combined voting
                          power of all classes of stock of the Company or an
                          Affiliate, each ISO shall terminate not more than ten
                          (10) years from the date of the grant or at such
                          earlier time as the Option Agreement may provide; or

                   ii.    More than ten percent (10%) of the total combined
                          voting power of all classes of stock of the Company or
                          an Affiliate, each ISO shall terminate not more than
                          five (5) years from the date of the grant or at such
                          earlier time as the Option Agreement may provide.

            d.     LIMITATION ON YEARLY EXERCISE: The Option Agreements shall
                   restrict the amount of ISOs which may become exercisable in
                   any calendar year (under this or any other ISO plan of the
                   Company or an Affiliate) so that the aggregate Fair Market
                   Value (determined at the time each ISO is granted) of the
                   stock with respect to which ISOs are exercisable for the
                   first time by the Participant in any calendar year does not
                   exceed $100,000.

7.     TERMS AND CONDITIONS OF STOCK GRANTS.

       Each offer of a Stock Grant to a Participant shall state the date prior
to which the Stock Grant must be accepted by the Participant, and the principal
terms of each Stock Grant shall be set forth in an Agreement, duly executed by
the Company and, to the extent required by law or requested by the Company, by
the Participant. The Agreement shall be in a form approved by the Administrator
and shall contain terms and conditions which the Administrator determines to be
appropriate and in the best interest of the Company, subject to the following
minimum standards:

       (a)  Each Agreement shall state the purchase price (per share), if any,
            of the Shares covered by each Stock Grant, which purchase price
            shall be determined by the Administrator but shall not be less than
            the minimum consideration required by the Delaware General
            Corporation Law on the date of the grant of the Stock Grant;

       (b)  Each Agreement shall state the number of Shares to which the Stock
            Grant pertains; and

       (c)  Each Agreement shall include the terms of any right of the Company
            to restrict or reacquire the Shares subject to the Stock Grant,
            including the time and events upon which such rights shall accrue
            and the purchase price therefor, if any.

                                       8
<Page>

8.     TERMS AND CONDITIONS OF OTHER STOCK-BASED AWARDS.

       The Administrator shall have the right to grant other Stock-Based Awards
based upon the Common Stock having such terms and conditions as the
Administrator may determine, including, without limitation, the grant of Shares
based upon certain conditions, the grant of securities convertible into Shares
and the grant of stock appreciation rights, phantom stock awards or stock units.
The principal terms of each Stock-Based Award shall be set forth in an
Agreement, duly executed by the Company and, to the extent required by law or
requested by the Company, by the Participant. The Agreement shall be in a form
approved by the Administrator and shall contain terms and conditions which the
Administrator determines to be appropriate and in the best interest of the
Company.

9.     EXERCISE OF OPTIONS AND ISSUE OF SHARES.

       An Option (or any part or installment thereof) shall be exercised by
giving written notice to the Company or its designee, together with provision
for payment of the full purchase price in accordance with this Paragraph for the
Shares as to which the Option is being exercised, and upon compliance with any
other condition(s) set forth in the Option Agreement. Such notice shall be
signed by the person exercising the Option, shall state the number of Shares
with respect to which the Option is being exercised and shall contain any
representation required by the Plan or the Option Agreement. Payment of the
purchase price for the Shares as to which such Option is being exercised shall
be made (a) in United States dollars in cash or by check, or (b) at the
discretion of the Administrator, through delivery of shares of Common Stock
having a Fair Market Value equal as of the date of the exercise to the cash
exercise price of the Option and held for at least six months, or (c) at the
discretion of the Administrator, by having the Company retain from the shares
otherwise issuable upon exercise of the Option, a number of shares having a Fair
Market Value equal as of the date of exercise to the exercise price of the
Option, or (d) at the discretion of the Administrator, by delivery of the
grantee's personal recourse note bearing interest payable not less than annually
at no less than 100% of the applicable Federal rate, as defined in Section
1274(d) of the Code, or (e) at the discretion of the Administrator, in
accordance with a cashless exercise program established with a securities
brokerage firm, and approved by the Administrator, or (f) at the discretion of
the Administrator, by any combination of (a), (b), (c), (d) and (e) above, or
(g) at the discretion of the Administrator, payment of such other lawful
consideration as the Administrator may determine. Notwithstanding the foregoing,
the Administrator shall accept only such payment on exercise of an ISO as is
permitted by Section 422 of the Code.

       The Company shall then reasonably promptly deliver the Shares as to which
such Option was exercised to the Participant (or to the Participant's Survivors,
as the case may be). In determining what constitutes "reasonably promptly," it
is expressly understood that the issuance and delivery of the Shares may be
delayed by the Company in order to comply with any law or regulation (including,
without limitation, state securities or "blue sky" laws) which requires the

                                       9
<Page>

Company to take any action with respect to the Shares prior to their issuance.
The Shares shall, upon delivery, be fully paid, non-assessable Shares.

       The Administrator shall have the right to accelerate the date of exercise
of any installment of any Option; provided that the Administrator shall not
accelerate the exercise date of any installment of any Option granted to an
Employee as an ISO (and not previously converted into a Non-Qualified Option
pursuant to Paragraph 27) without the prior approval of the Employee if such
acceleration would violate the annual vesting limitation contained in Section
422(d) of the Code, as described in Paragraph 6.B.d.

       The Administrator may, in its discretion, amend any term or condition of
an outstanding Option provided (i) such term or condition as amended is
permitted by the Plan, (ii) any such amendment shall be made only with the
consent of the Participant to whom the Option was granted, or in the event of
the death of the Participant, the Participant's Survivors, if the amendment is
adverse to the Participant, and (iii) any such amendment of any Option shall be
made only after the Administrator determines whether such amendment would
constitute a "modification" of any Option which is an ISO (as that term is
defined in Section 424(h) of the Code) or would cause any adverse tax
consequences for the holder of such Option including, but not limited to,
pursuant to Section 409A of the Code.

10.    ACCEPTANCE OF STOCK GRANTS AND STOCK-BASED AWARDS AND ISSUE OF SHARES.

       A Stock Grant or Stock-Based Award (or any part or installment thereof)
shall be accepted by executing the applicable Agreement and delivering it to the
Company or its designee, together with provision for payment of the full
purchase price, if any, in accordance with this Paragraph for the Shares as to
which such Stock Grant or Stock-Based Award is being accepted, and upon
compliance with any other conditions set forth in the applicable Agreement.
Payment of the purchase price for the Shares as to which such Stock Grant or
Stock-Based Award is being accepted shall be made (a) in United States dollars
in cash or by check, or (b) at the discretion of the Administrator, through
delivery of shares of Common Stock held for at least six months and having a
Fair Market Value equal as of the date of acceptance of the Stock Grant or
Stock-Based Award to the purchase price of the Stock Grant or Stock-Based Award,
or (c) at the discretion of the Administrator, by delivery of the grantee's
personal recourse note bearing interest payable not less than annually at no
less than 100% of the applicable Federal rate, as defined in Section 1274(d) of
the Code, or (d) at the discretion of the Administrator, by any combination of
(a), (b) and (c) above, or (e) at the discretion of the Administrator, payment
of such other lawful consideration as the Administrator may determine.

       The Company shall then, if required pursuant to the applicable Agreement,
reasonably promptly deliver the Shares as to which such Stock Grant or
Stock-Based Award was accepted to the Participant (or to the Participant's
Survivors, as the case may be), subject to any escrow provision set forth in the
applicable Agreement. In determining what constitutes "reasonably promptly," it
is expressly understood that the issuance and delivery of the Shares may be
delayed by the Company in order to comply with any law or regulation (including,
without limitation,

                                       10
<Page>

state securities or "blue sky" laws) which requires the Company to take any
action with respect to the Shares prior to their issuance.

       The Administrator may, in its discretion, amend any term or condition of
an outstanding Stock Grant, Stock-Based Award or applicable Agreement provided
(i) such term or condition as amended is permitted by the Plan, and (ii) any
such amendment shall be made only with the consent of the Participant to whom
the Stock Grant or Stock-Based Award was made, if the amendment is adverse to
the Participant.

11.    RIGHTS AS A SHAREHOLDER.

       No Participant to whom a Stock Right has been granted shall have rights
as a shareholder with respect to any Shares covered by such Stock Right, except
after due exercise of the Option or acceptance of the Stock Grant or as set
forth in any Agreement and tender of the full purchase price, if any, for the
Shares being purchased pursuant to such exercise or acceptance and registration
of the Shares in the Company's share register in the name of the Participant.

12.    ASSIGNABILITY AND TRANSFERABILITY OF STOCK RIGHTS.

       By its terms, a Stock Right granted to a Participant shall not be
transferable by the Participant other than (i) by will or by the laws of descent
and distribution, or (ii) as approved by the Administrator in its discretion and
set forth in the applicable Agreement. Notwithstanding the foregoing, an ISO
transferred except in compliance with clause (i) above shall no longer qualify
as an ISO. The designation of a beneficiary of a Stock Right by a Participant,
with the prior approval of the Administrator and in such form as the
Administrator shall prescribe, shall not be deemed a transfer prohibited by this
Paragraph. Except as provided above, a Stock Right shall only be exercisable or
may only be accepted, during the Participant's lifetime, by such Participant (or
by his or her legal representative) and shall not be assigned, pledged or
hypothecated in any way (whether by operation of law or otherwise) and shall not
be subject to execution, attachment or similar process. Any attempted transfer,
assignment, pledge, hypothecation or other disposition of any Stock Right or of
any rights granted thereunder contrary to the provisions of this Plan, or the
levy of any attachment or similar process upon a Stock Right, shall be null and
void.

13.    EFFECT ON OPTIONS OF TERMINATION OF SERVICE OTHER THAN "FOR CAUSE" OR
       DEATH OR DISABILITY.

       Except as otherwise provided in a Participant's Option Agreement in the
event of a termination of service (whether as an employee, director or
consultant) with the Company or an Affiliate before the Participant has
exercised an Option, the following rules apply:

       a.   A Participant who ceases to be an employee, director or consultant
            of the Company or of an Affiliate (for any reason other than
            termination "for cause",

                                       11
<Page>

            Disability, or death for which events there are special rules in
            Paragraphs 14, 15, and 16, respectively), may exercise any Option
            granted to him or her to the extent that the Option is exercisable
            on the date of such termination of service, but only within such
            term as the Administrator has designated in a Participant's Option
            Agreement.

       b.   Except as provided in Subparagraph (c) below, or Paragraph 15 or 16,
            in no event may an Option intended to be an ISO, be exercised later
            than three (3) months after the Participant's termination of
            employment.

       c.   The provisions of this Paragraph, and not the provisions of
            Paragraph 15 or 16, shall apply to a Participant who subsequently
            becomes Disabled or dies after the termination of employment,
            director status or consultancy; provided, however, in the case of a
            Participant's Disability or death within three (3) months after the
            termination of employment, director status or consultancy, the
            Participant or the Participant's Survivors may exercise the Option
            within one (1) year after the date of the Participant's termination
            of service, but in no event after the date of expiration of the term
            of the Option.

       d.   Notwithstanding anything herein to the contrary, if subsequent to a
            Participant's termination of employment, termination of director
            status or termination of consultancy, but prior to the exercise of
            an Option, the Board of Directors determines that, either prior or
            subsequent to the Participant's termination, the Participant engaged
            in conduct which would constitute "cause", then such Participant
            shall forthwith cease to have any right to exercise any Option.

       e.   A Participant to whom an Option has been granted under the Plan who
            is absent from the Company or an Affiliate because of temporary
            disability (any disability other than a Disability as defined in
            Paragraph 1 hereof), or who is on leave of absence for any purpose,
            shall not, during the period of any such absence, be deemed, by
            virtue of such absence alone, to have terminated such Participant's
            employment, director status or consultancy with the Company or with
            an Affiliate, except as the Administrator may otherwise expressly
            provide.

       f.   Except as required by law or as set forth in a Participant's Option
            Agreement, Options granted under the Plan shall not be affected by
            any change of a Participant's status within or among the Company and
            any Affiliates, so long as the Participant continues to be an
            employee, director or consultant of the Company or any Affiliate.

14.    EFFECT ON OPTIONS OF TERMINATION OF SERVICE "FOR CAUSE".

       Except as otherwise provided in a Participant's Option Agreement, the
following rules apply if the Participant's service (whether as an employee,
director or consultant) with the

                                       12
<Page>

Company or an Affiliate is terminated "for cause" prior to the time that all his
or her outstanding Options have been exercised:

       a.   All outstanding and unexercised Options as of the time the
            Participant is notified his or her service is terminated "for cause"
            will immediately be forfeited.

       b.   For purposes of this Plan, "cause" shall include (and is not limited
            to) dishonesty with respect to the Company or any Affiliate,
            insubordination, substantial malfeasance or non-feasance of duty,
            unauthorized disclosure of confidential information, breach by the
            Participant of any provision of any employment, consulting,
            advisory, nondisclosure, inventions assignment, non-competition or
            similar agreement between the Participant and the Company, and
            conduct substantially prejudicial to the business of the Company or
            any Affiliate. The determination of the Administrator as to the
            existence of "cause" will be conclusive on the Participant and the
            Company.

       c.   "Cause" is not limited to events which have occurred prior to a
            Participant's termination of service, nor is it necessary that the
            Administrator's finding of "cause" occur prior to termination. If
            the Administrator determines, subsequent to a Participant's
            termination of service but prior to the exercise of an Option, that
            either prior or subsequent to the Participant's termination the
            Participant engaged in conduct which would constitute "cause", then
            the right to exercise any Option is forfeited.

       d.   Any provision in an agreement between the Participant and the
            Company or an Affiliate, which contains a conflicting definition of
            "cause" for termination and which is in effect at the time of such
            termination, shall supersede the definition in this Plan with
            respect to that Participant.

15.    EFFECT ON OPTIONS OF TERMINATION OF SERVICE FOR DISABILITY.

       Except as otherwise provided in a Participant's Option Agreement, a
Participant who ceases to be an employee, director or consultant of the Company
or of an Affiliate by reason of Disability may exercise any Option granted to
such Participant:

       a.   To the extent that the Option has become exercisable but has not
            been exercised on the date of Disability; and

       b.   In the event rights to exercise the Option accrue periodically, to
            the extent of a pro rata portion through the date of Disability of
            any additional vesting rights that would have accrued on the next
            vesting date had the Participant not become Disabled. The proration
            shall be based upon the number of days accrued in the current
            vesting period prior to the date of Disability.

                                       13
<Page>

       A Disabled Participant may exercise such rights only within the period
ending one (1) year after the date of the Participant's Disability,
notwithstanding that the Participant might have been able to exercise the Option
as to some or all of the Shares on a later date if the Participant had not
become Disabled and had continued to be an employee, director or consultant or,
if earlier, within the originally prescribed term of the Option.

       The Administrator shall make the determination both of whether Disability
has occurred and the date of its occurrence (unless a procedure for such
determination is set forth in another agreement between the Company and such
Participant, in which case such procedure shall be used for such determination).
If requested, the Participant shall be examined by a physician selected or
approved by the Administrator, the cost of which examination shall be paid for
by the Company.

16.    EFFECT ON OPTIONS OF DEATH WHILE AN EMPLOYEE, DIRECTOR OR CONSULTANT.

       Except as otherwise provided in a Participant's Option Agreement, in the
event of the death of a Participant while the Participant is an employee,
director or consultant of the Company or of an Affiliate, such Option may be
exercised by the Participant's Survivors:

       a.   To the extent that the Option has become exercisable but has not
            been exercised on the date of death; and

       b.   In the event rights to exercise the Option accrue periodically, to
            the extent of a pro rata portion through the date of death of any
            additional vesting rights that would have accrued on the next
            vesting date had the Participant not died. The proration shall be
            based upon the number of days accrued in the current vesting period
            prior to the Participant's date of death.

       If the Participant's Survivors wish to exercise the Option, they must
take all necessary steps to exercise the Option within one (1) year after the
date of death of such Participant, notwithstanding that the decedent might have
been able to exercise the Option as to some or all of the Shares on a later date
if he or she had not died and had continued to be an employee, director or
consultant or, if earlier, within the originally prescribed term of the Option.

17.    EFFECT OF TERMINATION OF SERVICE ON UNACCEPTED STOCK GRANTS.

       In the event of a termination of service (whether as an employee,
director or consultant) with the Company or an Affiliate for any reason before
the Participant has accepted a Stock Grant, such offer shall terminate.

       For purposes of this Paragraph 17 and Paragraph 18 below, a Participant
to whom a Stock Grant has been offered and accepted under the Plan who is absent
from work with the Company or with an Affiliate because of temporary disability
(any disability other than a permanent and

                                       14
<Page>

total Disability as defined in Paragraph 1 hereof), or who is on leave of
absence for any purpose, shall not, during the period of any such absence, be
deemed, by virtue of such absence alone, to have terminated such Participant's
employment, director status or consultancy with the Company or with an
Affiliate, except as the Administrator may otherwise expressly provide.

       In addition, for purposes of this Paragraph 17 and Paragraph 18 below,
any change of employment or other service within or among the Company and any
Affiliates shall not be treated as a termination of employment, director status
or consultancy so long as the Participant continues to be an employee, director
or consultant of the Company or any Affiliate.

18.    EFFECT ON STOCK GRANTS OF TERMINATION OF SERVICE OTHER THAN "FOR CAUSE"
       OR DEATH OR DISABILITY.

       Except as otherwise provided in a Participant's Agreement, in the event
of a termination of service (whether as an employee, director or consultant),
other than termination "for cause," Disability, or death for which events there
are special rules in Paragraphs 19, 20, and 21, respectively, before all
forfeiture provisions or the Company's rights of repurchase shall have lapsed,
then the Company shall have the right to cancel or repurchase that number of
Shares subject to a Stock Grant as to which the Company's forfeiture or
repurchase rights have not lapsed.

19.    EFFECT ON STOCK GRANTS OF TERMINATION OF SERVICE "FOR CAUSE".

       Except as otherwise provided in a Participant's Agreement, the following
rules apply if the Participant's service (whether as an employee, director or
consultant) with the Company or an Affiliate is terminated "for cause":

       a.   All Shares subject to any Stock Grant shall be immediately subject
            to repurchase by the Company at the purchase price, if any, thereof.

       b.   For purposes of this Plan, "cause" shall include (and is not limited
            to) dishonesty with respect to the employer, insubordination,
            substantial malfeasance or non-feasance of duty, unauthorized
            disclosure of confidential information, breach by the Participant of
            any provision of any employment, consulting, advisory,
            nondisclosure, inventions assignment, non-competition or similar
            agreement between the Participant and the Company, and conduct
            substantially prejudicial to the business of the Company or any
            Affiliate. The determination of the Administrator as to the
            existence of "cause" will be conclusive on the Participant and the
            Company.

       c.   "Cause" is not limited to events which have occurred prior to a
            Participant's termination of service, nor is it necessary that the
            Administrator's finding of "cause" occur prior to termination. If
            the Administrator determines, subsequent to a Participant's
            termination of service, that either prior or subsequent to the

                                       15
<Page>

            Participant's termination the Participant engaged in conduct which
            would constitute "cause," then the Company's right to repurchase all
            of such Participant's Shares shall apply.

       d.   Any provision in an agreement between the Participant and the
            Company or an Affiliate, which contains a conflicting definition of
            "cause" for termination and which is in effect at the time of such
            termination, shall supersede the definition in this Plan with
            respect to that Participant.

20.    EFFECT ON STOCK GRANTS OF TERMINATION OF SERVICE FOR DISABILITY.

       Except as otherwise provided in a Participant's Agreement, the following
rules apply if a Participant ceases to be an employee, director or consultant of
the Company or of an Affiliate by reason of Disability: to the extent the
forfeiture provisions or the Company's rights of repurchase have not lapsed on
the date of Disability, they shall be exercisable; provided, however, that in
the event such forfeiture provisions or rights of repurchase lapse periodically,
such provisions or rights shall lapse to the extent of a pro rata portion of the
Shares subject to such Stock Grant through the date of Disability as would have
lapsed had the Participant not become Disabled. The proration shall be based
upon the number of days accrued prior to the date of Disability.

       The Administrator shall make the determination both of whether Disability
has occurred and the date of its occurrence (unless a procedure for such
determination is set forth in another agreement between the Company and such
Participant, in which case such procedure shall be used for such determination).
If requested, the Participant shall be examined by a physician selected or
approved by the Administrator, the cost of which examination shall be paid for
by the Company.

21.    EFFECT ON STOCK GRANTS OF DEATH WHILE AN EMPLOYEE, DIRECTOR OR
       CONSULTANT.

       Except as otherwise provided in a Participant's Agreement, the following
rules apply in the event of the death of a Participant while the Participant is
an employee, director or consultant of the Company or of an Affiliate: to the
extent the forfeiture provisions or the Company's rights of repurchase have not
lapsed on the date of death, they shall be exercisable; provided, however, that
in the event such forfeiture provisions or rights of repurchase lapse
periodically, such provisions or rights shall lapse to the extent of a pro rata
portion of the Shares subject to such Stock Grant through the date of death as
would have lapsed had the Participant not died. The proration shall be based
upon the number of days accrued prior to the Participant's death.

                                       16

22.    PURCHASE FOR INVESTMENT.

       Unless the offering and sale of the Shares to be issued upon the
particular exercise or acceptance of a Stock Right shall have been effectively
registered under the Securities Act of 1933, as now in force or hereafter
amended (the "1933 Act"), the Company shall be under no obligation to issue the
Shares covered by such exercise unless and until the following conditions have
been fulfilled:

       a.   The person(s) who exercise(s) or accept(s) such Stock Right shall
            warrant to the Company, prior to the receipt of such Shares, that
            such person(s) are acquiring such Shares for their own respective
            accounts, for investment, and not with a view to, or for sale in
            connection with, the distribution of any such Shares, in which event
            the person(s) acquiring such Shares shall be bound by the provisions
            of the following legend which shall be endorsed upon the
            certificate(s) evidencing their Shares issued pursuant to such
            exercise or such grant:

                   "The shares represented by this certificate have been taken
                   for investment and they may not be sold or otherwise
                   transferred by any person, including a pledgee, unless (1)
                   either (a) a Registration Statement with respect to such
                   shares shall be effective under the Securities Act of 1933,
                   as amended, or (b) the Company shall have received an opinion
                   of counsel satisfactory to it that an exemption from
                   registration under such Act is then available, and (2) there
                   shall have been compliance with all applicable state
                   securities laws."

       b.   At the discretion of the Administrator, the Company shall have
            received an opinion of its counsel that the Shares may be issued
            upon such particular exercise or acceptance in compliance with the
            1933 Act without registration thereunder.

23.    DISSOLUTION OR LIQUIDATION OF THE COMPANY.

       Upon the dissolution or liquidation of the Company, all Options granted
under this Plan which as of such date shall not have been exercised and all
Stock Grants and Stock-Based Awards which have not been accepted, will terminate
and become null and void; provided, however, that if the rights of a Participant
or a Participant's Survivors have not otherwise terminated and expired, the
Participant or the Participant's Survivors will have the right immediately prior
to such dissolution or liquidation to exercise or accept any Stock Right to the
extent that the Stock Right is exercisable or subject to acceptance as of the
date immediately prior to such dissolution or liquidation. Upon the dissolution
or liquidation of the Company, any outstanding Stock-Based Awards shall
immediately terminate unless otherwise determined by the Administrator or
specifically provided in the applicable Agreement.

                                       17

24.    ADJUSTMENTS.

       Upon the occurrence of any of the following events, a Participant's
rights with respect to any Stock Right granted to him or her hereunder shall be
adjusted as hereinafter provided, unless otherwise specifically provided in a
Participant's Agreement:

       A. STOCK DIVIDENDS AND STOCK SPLITS. If (i) the shares of Common Stock
shall be subdivided or combined into a greater or smaller number of shares or if
the Company shall issue any shares of Common Stock as a stock dividend on its
outstanding Common Stock, or (ii) additional shares or new or different shares
or other securities of the Company or other non-cash assets are distributed with
respect to such shares of Common Stock, the number of shares of Common Stock
deliverable upon the exercise of an Option or acceptance of a Stock Grant shall
be appropriately increased or decreased proportionately, and appropriate
adjustments shall be made including, in the purchase price per share to reflect
such events. The number of Shares subject to the limitations in Paragraphs 3(a),
3(b) and 4(c) shall also be proportionately adjusted upon the occurrence of such
events.

       B. CORPORATE TRANSACTIONS. If the Company is to be consolidated with or
acquired by another entity in a merger, sale of all or substantially all of the
Company's assets other than a transaction to merely change the state of
incorporation (a "Corporate Transaction"), the Administrator or the board of
directors of any entity assuming the obligations of the Company hereunder (the
"Successor Board"), shall, as to outstanding Options, either (i) make
appropriate provision for the continuation of such Options by substituting on an
equitable basis for the Shares then subject to such Options either the
consideration payable with respect to the outstanding shares of Common Stock in
connection with the Corporate Transaction or securities of any successor or
acquiring entity; or (ii) upon written notice to the Participants, provide that
all Options must be exercised, within a specified number of days of the date of
such notice at the end of which period the Options shall terminate (all Options
shall for purposes of this clause (ii) be made fully vested and exercisable
immediately prior to their termination); or (iii) terminate all Options in
exchange for a cash payment equal to the excess of the Fair Market Value of the
Shares subject to such Options over the exercise price thereof (all Options
shall for purposes of this clause (iii) be made fully vested and immediately
exercisable immediately prior to their termination).

       With respect to outstanding Stock Grants, the Administrator or the
Successor Board, shall either (i) make appropriate provisions for the
continuation of such Stock Grants on the same terms and conditions by
substituting on an equitable basis for the Shares then subject to such Stock
Grants either the consideration payable with respect to the outstanding Shares
of Common Stock in connection with the Corporate Transaction or securities of
any successor or acquiring entity; or (ii) terminate all Stock Grants in
exchange for a cash payment equal to the excess of the Fair Market Value of the
Shares (without regard to repurchase rights of the Company) subject to such
Stock Grants over the purchase price thereof, if any.

       C. RECAPITALIZATION OR REORGANIZATION. In the event of a recapitalization
or reorganization of the Company, other than a Corporate Transaction, pursuant
to which securities of the Company or of another corporation are issued with
respect to the outstanding shares of

                                       18
<Page>

Common Stock, a Participant upon exercising an Option or accepting a Stock Grant
after the recapitalization or reorganization shall be entitled to receive for
the purchase price paid upon such exercise or acceptance the number of
replacement securities which would have been received if such Option had been
exercised or Stock Grant accepted prior to such recapitalization or
reorganization.

       D. ADJUSTMENTS TO STOCK-BASED AWARDS. Upon the happening of any of the
events described in Subparagraphs A, B or C above, any outstanding Stock-Based
Award shall be appropriately adjusted to reflect the events described in such
Subparagraphs. The Administrator or the Successor Board shall determine the
specific adjustments to be made under this Paragraph 24 and, subject to
Paragraph 4, its determination shall be conclusive.

       E. MODIFICATION OF ISOs. Notwithstanding the foregoing, any adjustments
made pursuant to Subparagraph A, B or C above with respect to ISOs shall be made
only after the Administrator determines whether such adjustments would
constitute a "modification" of such ISOs (as that term is defined in Section
424(h) of the Code) or would cause any adverse tax consequences for the holders
of such ISOs. If the Administrator determines that such adjustments made with
respect to ISOs would constitute a modification of such ISOs, it may refrain
from making such adjustments, unless the holder of an ISO specifically agrees in
writing that such adjustment be made and such writing indicates that the holder
has full knowledge of the consequences of such "modification" on his or her
income tax treatment with respect to the ISO. This paragraph shall not apply to
the acceleration of the vesting of any ISO that would cause any portion of the
ISO to violate the annual vesting limitation contained in Section 422(d) of the
Code, as described in Paragraph 6(B)(d).

       F. CHANGE OF CONTROL. In the event of either

            (A) a Corporate Transaction that also constitutes a Change of
Control, where outstanding options are assumed or substituted in accordance with
the first paragraph of Subparagraph B clause (i) above and, with respect to
Stock Grants, in accordance with the second paragraph of Subparagraph B clause
(i); or

            (B) a Change of Control that does not also constitute a Corporate
Transaction,

if within six months after the date of such Change of Control, (i) a
Participant's service is terminated by the Company or an Affiliate for any
reason other than Cause; or (ii) a Participant terminates his or her service as
a result of being required to change the principal location where he or she
renders services to a location more than 50 miles from his or her location of
employment or consultancy immediately prior to the Change of Control; or (iii)
the Participant terminates his or her service after there occurs a material
adverse change in a Participant's duties, authority or responsibilities which
causes such Participant's position with the Company to become of significantly
less responsibility or authority than such Participant's position was
immediately prior to the Change of Control, THEN all of such Participant's
Options outstanding under the Plan shall become fully vested and immediately
exercisable as of the date of termination of such Participant, unless in any
such case an Option has otherwise expired or been terminated pursuant

                                       19
<Page>

to its terms or the terms of the Plan and any repurchase rights of the Company
with respect to outstanding Stock Grants that have not lapsed or expired prior
to such Change of Control shall terminate as of the date of termination of such
Participant.

25.    ISSUANCES OF SECURITIES.

       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 price of shares subject to Stock Rights. Except as
expressly provided herein, no adjustments shall be made for dividends paid in
cash or in property (including without limitation, securities) of the Company
prior to any issuance of Shares pursuant to a Stock Right.

26.    FRACTIONAL SHARES.

       No fractional shares shall be issued under the Plan and the person
exercising a Stock Right shall receive from the Company cash in lieu of such
fractional shares equal to the Fair Market Value thereof.

27.    CONVERSION OF ISOs INTO NON-QUALIFIED OPTIONS; TERMINATION OF ISOs.

       The Administrator, at the written request of any Participant, may in its
discretion take such actions as may be necessary to convert such Participant's
ISOs (or any portions thereof) that have not been exercised on the date of
conversion into Non-Qualified Options at any time prior to the expiration of
such ISOs, regardless of whether the Participant is an employee of the Company
or an Affiliate at the time of such conversion. At the time of such conversion,
the Administrator (with the consent of the Participant) may impose such
conditions on the exercise of the resulting Non-Qualified Options as the
Administrator in its discretion may determine, provided that such conditions
shall not be inconsistent with this Plan. Nothing in the Plan shall be deemed to
give any Participant the right to have such Participant's ISOs converted into
Non-Qualified Options, and no such conversion shall occur until and unless the
Administrator takes appropriate action. The Administrator, with the consent of
the Participant, may also terminate any portion of any ISO that has not been
exercised at the time of such conversion.

28.    WITHHOLDING.

       In the event that any federal, state, or local income taxes, employment
taxes, Federal Insurance Contributions Act ("F.I.C.A.") withholdings or other
amounts are required by applicable law or governmental regulation to be withheld
from the Participant's salary, wages or other remuneration in connection with
the exercise or acceptance of a Stock Right or in connection with a
Disqualifying Disposition (as defined in Paragraph 29) or upon the lapsing of

                                       20
<Page>

any forfeiture provision or right of repurchase or for any other reason required
by law, the Company may withhold from the Participant's compensation, if any, or
may require that the Participant advance in cash to the Company, or to any
Affiliate of the Company which employs or employed the Participant, the
statutory minimum amount of such withholdings unless a different withholding
arrangement, including the use of shares of the Company's Common Stock or a
promissory note, is authorized by the Administrator (and permitted by law). For
purposes hereof, the fair market value of the shares withheld for purposes of
payroll withholding shall be determined in the manner provided in Paragraph 1
above, as of the most recent practicable date prior to the date of exercise. If
the fair market value of the shares withheld is less than the amount of payroll
withholdings required, the Participant may be required to advance the difference
in cash to the Company or the Affiliate employer. The Administrator in its
discretion may condition the exercise of an Option for less than the then Fair
Market Value on the Participant's payment of such additional withholding.

29.    NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION.

       Each Employee who receives an ISO must agree to notify the Company in
writing immediately after the Employee makes a "Disqualifying Disposition" of
any shares acquired pursuant to the exercise of an ISO. A Disqualifying
Disposition is defined in Section 424(c) of the Code and includes any
disposition (including any sale or gift) of such shares before the later of (a)
two years after the date the Employee was granted the ISO, or (b) one year after
the date the Employee acquired Shares by exercising the ISO, except as otherwise
provided in Section 424(c) of the Code. If the Employee has died before such
stock is sold, these holding period requirements do not apply and no
Disqualifying Disposition can occur thereafter.

30.    TERMINATION OF THE PLAN.

       The Plan will terminate on March 15, 2016 the date which is ten (10)
years from the EARLIER of the date of its adoption by the Board of Directors and
the date of its approval by the shareholders of the Company. The Plan may be
terminated at an earlier date by vote of the shareholders or the Board of
Directors of the Company; provided, however, that any such earlier termination
shall not affect any Agreements executed prior to the effective date of such
termination.

31.    AMENDMENT OF THE PLAN AND AGREEMENTS.

       The Plan may be amended by the shareholders of the Company. The Plan may
also be amended by the Administrator, including, without limitation, to the
extent necessary to qualify any or all outstanding Stock Rights granted under
the Plan or Stock Rights to be granted under the Plan for favorable federal
income tax treatment (including deferral of taxation upon exercise) as may be
afforded incentive stock options under Section 422 of the Code, and to the
extent necessary to qualify the shares issuable upon exercise or acceptance of
any outstanding Stock Rights granted, or Stock Rights to be granted, under the
Plan for listing on any national securities

                                       21
<Page>

exchange or quotation in any national automated quotation system of securities
dealers. Any amendment approved by the Administrator which the Administrator
determines is of a scope that requires shareholder approval shall be subject to
obtaining such shareholder approval. Any modification or amendment of the Plan
shall not, without the consent of a Participant, adversely affect his or her
rights under a Stock Right previously granted to him or her. With the consent of
the Participant affected, the Administrator may amend outstanding Agreements in
a manner which may be adverse to the Participant but which is not inconsistent
with the Plan. In the discretion of the Administrator, outstanding Agreements
may be amended by the Administrator in a manner which is not adverse to the
Participant.

32.    EMPLOYMENT OR OTHER RELATIONSHIP.

       Nothing in this Plan or any Agreement shall be deemed to prevent the
Company or an Affiliate from terminating the employment, consultancy or director
status of a Participant, nor to prevent a Participant from terminating his or
her own employment, consultancy or director status or to give any Participant a
right to be retained in employment or other service by the Company or any
Affiliate for any period of time.

33.    GOVERNING LAW.

       This Plan shall be construed and enforced in accordance with the law of
the State of Delaware.

                                    22
