exercised in full, the unpurchased Shares which were subject thereto shall
become available for future grant or sale under the Plan (unless the Plan has
terminated), PROVIDED, however, that Shares that have actually been issued and
fully paid for under the Plan shall not be returned to the Plan and shall not
become available for future distribution under the Plan.

     4. ADMINISTRATION OF THE PLAN.

        (a) PROCEDURE. The Plan shall be administered by the Administrator.

        (b) POWERS OF THE ADMINISTRATOR. Subject to the provisions of the Plan
and the approval of any relevant authorities, the Administrator shall have the
authority, in its discretion:

            (i)    to determine the Fair Market Value;

            (ii)   to select the Service Providers to whom Options may from time
to time be granted hereunder;

            (iii)  to determine the number of Shares to be covered by each such
award granted hereunder;

            (iv)   approve forms of agreement for use under the Plan;

hereunder;

                                       3
<PAGE>

            (vi)   to determine whether and under what circumstances an Option
may be settled in cash under subsec tion 9(e) instead of Shares;

            (vii)  to reduce the exercise price of any Option to the then
current Fair Market Value (or the nominal value of the Shares, if higher than
the Fair Market Value), if the Fair Market Value of the Shares covered by such
Option has declined since the date the Option was granted;

            (viii) to prescribe, amend and rescind rules and regulations
relating to the Plan;

            (ix)   to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan.

        (c) EFFECT OF ADMINISTRATOR'S DECISION. All decisions, determinations
and interpretations of the Administrator shall be final and binding on all
Optionees.

     5. ELIGIBILITY. Nonstatutory Stock Options may be granted to Service
Providers. Incentive Stock Options may be granted only to Employees.

     6. LIMITATIONS.

        (a) Each Option shall be designated in the Option Agreement as either an
Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding
such designation, to the extent that the aggregate Fair Market Value of the
Shares with respect to which Incentive Stock Options are exercisable for the
first time by the Optionee during any calendar year (under all plans of the
Company and any Parent or Subsidiary) exceeds $100,000, such Options shall be
treated as Nonstatutory Stock Options. For purposes of this Section 6(a),
Incentive Stock Options shall be taken into account in the order in which they
were granted. The Fair Market Value of the Shares shall be determined as of the
time the Option with respect to such Shares is granted.

        (b) Neither the Plan nor any Option shall confer upon an Optionee any
right with respect to continuing the Optionee's relationship as a Service
Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

        (c) The following limitations shall apply to grants of Options:

            (i)    No Service Provider shall be granted, in any fiscal year of
the Company, Options to purchase more than 1,500,000 Shares.

            (ii)   In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 3,000,000
Shares, which shall not count against the limit set forth in subsection (i)
above.

            (iii)  The foregoing limitations shall be adjusted proportionately
in connection with any change in the Company's capitalization as described in
Section 12.

                                       4
<PAGE>

            (iv)   If an Option is cancelled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 12), the cancelled Option will be counted against the
limits set forth in subsections (i) and (ii) above. For this purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option.

     7. TERM OF PLAN. The Plan shall become effective upon its adoption by the
Board. It shall continue in effect for a term of ten (10) years unless sooner
terminated under Section 14 of the Plan.

     8. TERM OF OPTION. The term of each Option shall be stated in the Option
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof. In the case of an Incentive Stock Option granted
to an Optionee who, at the time the Option is granted, owns shares representing
more than ten percent (10%) of the voting power of all classes of shares of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant or such shorter term as may be provided in the
Option Agreement.

     9. OPTION EXERCISE PRICE AND CONSIDERATION.

        (a) The per share exercise price for the Shares to be issued pursuant to
exercise of an Option shall be such price as is determined by the Administrator,
but shall be subject to the following:

            (i)    In the case of an Incentive Stock Option

                   (A) granted to an Employee who, at the time of the grant of
such Incentive Stock Option, owns shares representing more than ten percent
(10%) of the voting power of all classes of shares of the Company or any Parent
or Subsidiary, the exercise price shall be no less than 110% of the Fair Market
Value per Share on the date of grant.

                   (B)granted to any Employee other than an Employee described
in the preceding subparagraph, the per Share exercise price shall be no less
than 100% of the Fair Market Value per Share on the date of grant.

            (ii)   In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Administrator.

            (iii)  Notwithstanding the foregoing, Options may be granted with a
per Share exercise price (other than as required above) of less than 100% of
Fair Market Value on the date of grant pursuant to a merger or other corporate
transaction.

        (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) consideration received by the Company under a formal cashless
exercise program adopted by the Company in connection with the Plan, (4) any
other type of consideration permitted by Applicable Laws, or (5) any combination
of the foregoing methods of payment. To the

                                       5
<PAGE>

extent that the consideration paid for the Shares is denominated in a currency
other than New Israeli Shekels, the exchange rate to be used to obtain a New
Israeli Shekel value of such consideration shall be the noon buying rate as
reported by the Federal Reserve Bank of New York (expressed in shekels per unit
of non-Israeli currency) on the date of grant of the Option. In making its
determination as to the type of consideration to accept, the Administrator shall
consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

     10. EXERCISE OF OPTION AND/OR TRUSTEE.

        (a) PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any Option granted
hereunder shall be exercisable according to the terms of the Plan and at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement. Options shall become exercisable at a rate to be
determined by the Administrator. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence. An Option may not be exercised for a fraction of a Share.

            An Option shall be deemed exercised when the Company receives: (i)
written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in (i) the name of the Optionee or,
if requested by the Optionee, in the name of the Optionee and his or her spouse,
or (ii) the name of the Optionee to the Trustee (as defined in paragraph (e)
below), if applicable, to be held by the Trustee on behalf of Optionee if so
required by Applicable Laws. Until the Shares are issued (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company), no right to vote or receive dividends or any other rights
as a shareholder shall exist with respect to the Shares, notwithstanding the
exercise of the Option. The Company shall issue (or cause to be issued) such
Shares promptly after the Option is exercised. No adjustment will be made for a
dividend or other right for which the record date is prior to the date the
Shares are issued, except as provided in Section 12 of the Plan.

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

        (b) TERMINATION OF RELATIONSHIP AS A SERVICE PROVIDER. If an Optionee
ceases to be a Service Provider, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the

                                       6
<PAGE>

Administrator, the Option shall terminate, and the Shares covered by such Option
shall revert to the Plan.

        (c) DISABILITY OF OPTIONEE. If an Optionee ceases to be a Service
Provider as a result of the Optionee's disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
to the extent the Option is vested on the date of termination, but in no event
later than the expiration date of the term of such Option as set forth in the
Option Agreement. In the absence of a specified time in the Option Agreement,
the Option shall remain exercisable for twelve (12) months following the
Optionee's termination. If, on the date of termination, the Optionee is not
vested as to the entire Option, the Shares covered by the unvested portion of
the Option shall revert to the Plan. If, after termination, the Option is not
exercised within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan. If such disability is
not a "disability" as such term is defined in Section 22(e)(3) of the Code, in
the case of an Incentive Stock Option such Incentive Stock Option shall
automatically cease to be treated as an Incentive Stock Option and shall be
treated for tax purposes as a Nonstatutory Stock Option on the day three months
and one day following such termination.

        (d) DEATH OF OPTIONEE. If an Optionee dies while a Service Provider, the
Option may be exercised within such period of time as is specified in the Option
Agreement to the extent that the Option is vested on the date of death (but in
no event later than the expiration of the term of such Option as set forth in
the Option Agreement) by the Optionee's estate or by a person who acquires the
right to exercise the Option by bequest or inheritance. In the absence of a
specified time in the Option Agreement, the Option shall remain exercisable for
twelve (12) months following the Optionee's termination. If, at the time of
death, the Optionee is not vested as to the entire Option, the Shares covered by
the unvested portion of the Option shall revert to the Plan. If the Option is
not so exercised within the time specified herein, the Option shall terminate,
and the Shares covered by such Option shall revert to the Plan.

        (e) Appointment of Trustee. In the event that the Company chooses to
elect a Trustee with respects to Options issued to Israeli Employees, the
Options which shall be granted to Optionees shall be issued to the Trustee
nominated by the Board (the "TRUSTEE") and held for the benefit of the Optionees
from the date of grant.

            Anything to the contrary notwithstanding, neither the Company nor
the Trustee shall release any Options and/or any Shares issued upon exercise of
Options, prior to the full payment of the Optionee's tax liabilities arising
from Options which were granted to him and/or any Shares issued upon exercise of
such Options.

            Optionee's signature on the Option Agreement (as such term is
defined in Section 2(q)) shall be construed as an undertaking of the Optionee to
release the Trustee from any liability in respect of any action or decision duly
taken and BONA FIDE executed in relation with the 2000 Share Option Plan, or any
Option or Share granted to him thereunder.

     11. NON-TRANSFERABILITY OF OPTIONS. Unless determined otherwise by the
Administrator, Options may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner

                                       7
<PAGE>

other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee.

     12. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

        (a) CHANGES IN CAPITALIZATION. In the event the Shares shall be
subdivided or combined into a greater or smaller number of Shares or if, upon a
reorganization, recapitalization or the like, the Shares shall be exchanged for
other securities of the Company, each Optionee shall be entitled, subject to the
conditions herein stated, to purchase such number of Shares or amount of other
securities of the Company as were exchangeable for the number of Shares of the
Company which such Optionee would have been entitled to purchase except for such
action, and appropriate adjustments shall be made in the purchase price per
share to reflect such subdivision, combination or exchange.

        In the event that the Company shall issue any of its Shares or other
securities as bonus shares or a stock dividend upon or with respect to any
Shares which shall at the time be subject to an Option hereunder, each Optionee
upon exercising such Option shall be entitled to receive (for the purchase price
payable upon such exercise), the Shares as to which he or she is exercising such
Option and, in addition thereto (at no additional cost), such number of shares
of the class or classes in which such bonus shares or stock dividend were
declared, and such amount of Shares (and the amount in lieu of fractional
Shares) as is equal to the Shares which he would have received had he been the
holder of the Shares as to which he is exercising his Option at all times
between the date of the granting of such Option and the date of its exercise.

        Upon the occurrence of any of the foregoing events, the class and
aggregate number of Shares or other securities issuable pursuant to the Plan, in
respect of which Options have not yet been granted, shall also be appropriately
adjusted to reflect the events specified above. If the Company offers the
holders of the Shares, or of any other class of security for which the Options
are then exercisable, rights to purchase securities of the Company, then the
Company shall offer the same rights to the Optionees as if they had exercised
their Options on the record date with respect to such rights offering.

        (b) DISSOLUTION OR LIQUIDATION. In the event of the proposed dissolution
or liquidation of the Company, the Administrator shall notify each Optionee as
soon as practicable prior to the effective date of such proposed transaction.
The Administrator in its discretion may provide for an Optionee to have the
right to exercise his or her Option until fifteen (15) days prior to such
transaction as to all of the Optioned Shares, including Shares as to which the
Option would not otherwise be exercisable. To the extent it has not been
previously exercised, an Option will terminate immediately prior to the
consummation of such proposed action.

        (c) MERGER OR ASSET SALE. In the event of a merger of the Company with
or into another corporation, or the sale of substantially all of the assets of
the Company, each outstanding Option shall be assumed or an equivalent option
substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation. In the event that the successor corporation refuses to
assume or substitute for the Option, the Optionee shall fully vest in and have
the right to exercise the Option as to all of the Optioned Shares, including
Shares as to which it would not otherwise be

                                       8
<PAGE>

vested or exercisable. For the purposes of this paragraph, the Option shall be
considered assumed if, following the merger or sale of assets, the option
confers the right to purchase or receive, for each Optioned Shares immediately
prior to the merger or sale of assets, the consideration (whether shares, cash,
or other securities or property) received in the merger or sale of assets by
holders of Shares for each Share held on the effective date of the transaction
(and if such holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or sale of
assets is not solely ordinary shares (or their equivalent) of the successor
corporation or its Parent, the Administrator may, with the consent of the
successor corporation, provide for the consideration to be received upon the
exercise of the Option, for each Optioned Share, to be solely ordinary shares
(or their equivalent) of the successor corporation or its Parent equal in fair
market value to the per Share consideration received by holders of in the merger
or sale of assets.

     13. DATE OF GRANT. The date of grant of an Option shall, for all purposes,
be the date on which the Administrator makes the determination granting such
Option, or such other date as is determined by the Board. Notice of the
determination shall be given to each Service Provider to whom an Option is so
granted within a reasonable time after the date of such grant.

     14. AMENDMENT AND TERMINATION OF THE PLAN.

        (a) AMENDMENT AND TERMINATION. The Board may at any time, but after
consultation with the Trustee, if such Trustee has been nominated, amend, alter,
suspend or terminate the Plan.

        (b) SHAREHOLDER APPROVAL. The Board shall obtain shareholder approval of
any Plan amendment to the extent necessary and desirable to comply with
Applicable Laws.

        (c) EFFECT OF AMENDMENT OR TERMINATION. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

     15. CONDITIONS UPON ISSUANCE OF SHARES.

        (a) LEGAL COMPLIANCE. Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

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

                                       9
<PAGE>

     16. INABILITY TO OBTAIN AUTHORITY. The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

     17. RESERVATION OF SHARES. The Company, during the term of this Plan, shall
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     18. SHAREHOLDER APPROVAL. The Plan shall be subject to approval by the
shareholders of the Company within twelve (12) months after the date the Plan is
adopted. Option grants to Office Holders shall also be subject to approval by
the shareholders of the Company. In each case, such shareholder approval shall
be obtained in the manner and to the degree, if any, required under Applicable
Laws and the Articles of Association of the Company.

event of a conflict between the terms and conditions of the Plan and this Option
Agreement, the terms and conditions of the Plan shall prevail.

     If designated in the Notice of Grant as an Incentive Stock Option ("ISO"),
this Option is intended to qualify as an Incentive Stock Option as defined in
Section 422 of the Code. Nevertheless, to the extent that it exceeds the
$100,000 rule of Code Section 422(d), this Option shall be treated as a
Nonstatutory Stock Option ("NSO").

     2. EXERCISE OF OPTION.

        (A) RIGHT TO EXERCISE. This Option shall be exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Grant and with
the applicable provisions of the Plan and this Option Agreement.

an exercise notice in the form attached as EXHIBIT A (the "Exercise Notice")
which shall state the election to exercise the Option, the number of Shares with
respect to which the Option is being exercised, and such other representations
and agreements as may be required by the Company. The Exercise Notice shall be
accompanied by payment of the aggregate Exercise Price as to all Exercised
Shares. This Option shall be deemed to be exercised upon receipt by the Company
of such fully executed Exercise Notice accompanied by the aggregate Exercise
Price.

        No Shares shall be issued pursuant to the exercise of an Option unless
such issuance and such exercise comply with Applicable Laws. Assuming such
compliance, for income tax purposes the Shares shall be considered transferred
to the Optionee on the date on which the Option is exercised with respect to

by any of the following, or a combination thereof, at the election of the

        (A) cash or check;

        (B) consideration received by the Company under a formal cashless

Company, (i) have been owned by the Optionee for more than six (6) months on the
date of surrender, and (ii) have a Fair Market Value on the date of surrender
equal to the aggregate Exercise Price of the Exercised Shares.

     4. RESTRICTIONS ON EXERCISE. This Option may not be exercised until such
time as the Plan has been approved by the shareholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any Applicable
Law.

     5. NON-TRANSFERABILITY OF OPTION. This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by Optionee. The terms of
the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

     6. TERM OF OPTION. This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.

     7. TAX OBLIGATIONS.

        (A) WITHHOLDING TAXES. Optionee agrees to make appropriate arrangements
with the Company (or the Parent or Subsidiary employing or retaining Optionee)
for the satisfaction of all Federal, state, and local income and employment tax
withholding requirements applicable to the Option exercise. Optionee
acknowledges and agrees that the Company may refuse to honor the exercise and
refuse to deliver Shares if such withholding amounts are not delivered at the
time of exercise.

        (B) NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES. If the Option
granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with

Optionee's interest except by means of a writing signed by the Company and
Optionee. This agreement is governed by the internal substantive laws but not

     9. NO GUARANTEE OF CONTINUED SERVICE. OPTIONEE ACKNOWLEDGES AND AGREES
THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED
ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH

             THE SILICON GROUP, INC. NONSTATUTORY STOCK OPTION PLAN

     1.   Purpose of the Plan. The purposes of this Nonstatutory Stock Option
Plan are to promote the interests of the Company by providing Employees and
Consultants of the Company with the opportunity to acquire a proprietary
interest, or otherwise increase their proprietary interest, in the Company as an
incentive for them to remain in the service of the Company.

     2.   Definitions. As used herein, the following definitions shall apply:

     "Board" shall mean the Board of Directors of the Company.

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

     "Common Stock" shall mean the common stock of the Company.

     "Company" shall mean The Silicon Group, Inc., a Texas corporation.

     "Consultant" shall mean any person who is engaged by the Company to render
services and is compensated for such services.

     "Employee" shall mean any person, including officers and directors,
employed by the Company.

     "Option" shall mean a stock option granted pursuant to the Plan.

     "Optioned Stock" shall mean the Common Stock subject to an Option.

     "Optionee" shall mean an Employee or Consultant who receives an Option.

     "Plan" shall mean this Nonstatutory Stock Option Plan.

the Plan, the maximum aggregate number of shares which may be optioned and sold
under the Plan is 3,694,836 shares of Common Stock. The Shares may be
authorized, but unissued, or reacquired Common Stock. If an Option should expire
or become unexercisable for any reason without having been exercised in full,

(ii) to determine the exercise price per share of Options to be granted; (iii)
to determine the Employees or Consultants to whom, and the time or times at
which, Options shall be granted and the number of shares to be represented by
each Option; (iv) to interpret the Plan; (v) to prescribe, amend and rescind
rules and regulations relating to the Plan; (vi) to determine the terms and
provisions of each Option granted (which need not be identical) and, with the
consent of the holder thereof, modify or amend each Option; (vii) to accelerate
or defer (with the consent of the Optionee) the exercise date of any Option;

<PAGE>   2

          (c)  Effect of Board's Decision. All decisions, determinations and
interpretations of the Board shall be final and binding on all Optionees and any
other holders of any Options granted under the Plan.

     5.   Eligibility.

          (a)  Options may be granted only to Employees and Consultants. An
Employee or Consultant who has been granted an Option may, if he is otherwise
eligible, be granted an additional Option or Options.

          (b)  The Plan shall not confer upon any Optionee any right with
respect to continuation of employment or consulting relationship with the
Company nor shall it interfere in any way with his right or the Company's right
to terminate his employment or consulting relationship at any time.

     6.   Term of Plan. The Plan shall become effective upon its adoption by the
Board. It shall continue in effect for a term of ten (10) years unless sooner
terminated under Section 13 of the Plan.

     7.   Term of Option. The term of each Option shall be ten (10) years from
the date of grant thereof or such shorter term as may be provided in the Stock
Option Agreement.

     8.   Exercise Price and Consideration.

          (a)  The per Share exercise price for the Shares to be issued pursuant
to exercise of an Option shall be such price as is determined by the Board.

          (b)  The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Board and may consist entirely of cash, check, other shares of Common Stock
having a fair market value on the date of surrender equal to the aggregate
exercise price of the Shares as to which said Option shall be exercised, or any
combination of such methods of payment, or such other consideration and method
of payment for the issuance of Shares to the extent permitted under applicable
law.

     9.   Exercise of Option.

          (a)  Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Board, including performance criteria with respect to the
Company or the Optionee, and as shall be permissible under the terms of the
Plan.

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

     An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment, as authorized by the Board, may consist of a
consideration and method of payment allowable under section 8(b) of the Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of the duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. No adjustment will be made for a
dividend or other right for which the record date is prior to the date the stock
certificate is issued, except as provided in Section 11 of the Plan. Prior to
the time of issuance, the Company shall satisfy its employment tax and other tax
withholding obligations by requiring the Optionee to pay the amount of
withholding tax, if any, that must be paid under federal, state and local law
due to the exercise of the Option, subject to such restrictions or procedures as
the Company deems necessary to satisfy Rule 16b-3 of the Exchange Act of 1934,
as amended. The payment of such withholding tax may be by certified or official
bank check or by the delivery of a number of shares of Common Stock (plus cash
if necessary) having a fair market value equal to the amount of such withholding
tax.

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

          (b)  Termination of Status as an Employee or Consultant. If any
Employee or Consultant ceases to serve as an Employee or Consultant (as the case
may be), then each Option granted to such Optionee and exercisable on the date
of such termination shall remain exercisable, and the Optionee may exercise each
such Option at any time within six (6) months after the date the Optionee ceases
to be an Employee or Consultant (as the case may be) of the Company; provided,
however, that if the Optionee is terminated other than for Cause (as defined
below) or voluntarily terminates as a result of a Constructive Termination (as
defined below), then the exercisability of each Option granted to such Optionee
and outstanding under the Plan on such date shall automatically accelerate so
that each such Option shall become fully exercisable with respect to the total
number of shares of Optioned Stock, and the Optionee may exercise each Option at
any time within six (6) months after the date the Optionee ceases to be an
Employee or Consultant (as the case may be) of the Company. To the extent that
the Optionee does not exercise such Option within the time specified herein, the
Option shall terminate.

     For purposes of this Section 9(b), "Cause" shall mean: (i) any material
breach by the Optionee of his fiduciary duties and responsibilities to the
Company having a material adverse effect on the business, reputation or
operations of the Company; (ii) the Optionee's engagement in acts of
embezzlement, dishonesty or moral turpitude having a material adverse effect on
the business, reputation or operations of the Company, (iii) the conviction of
the Optionee for a felony or (iv) gross negligence, bad faith or the repeated
failure of the Optionee to perform his duties and responsibilities to the
reasonable satisfaction of the Company. For purposes of this Section 9(b),
"Constructive Termination" shall mean, if within 60 days prior to the
resignation of the Optionee, any of the following shall have occurred: (i) there
shall have been a material reduction in the Optionee's compensation, material
benefits, job responsibilities or duties as an employee with the Company or (ii)
the Company shall have required as a condition of the Optionee's continued
employment that he relocate to a location which is more than 50 miles from the
Company's current Austin, Texas office.

          (c)  Disability of Optionee. Notwithstanding the provisions of Section
9(b) above, in the event an Employee or Consultant is unable to continue his
employment or consulting relationship (as the case may be) with the Company as a
result of his total and permanent disability (as defined in Section 22(e)(3) of
the Code), then the exercisability of each Option granted to such Optionee and
outstanding under the Plan shall automatically accelerate so that each such
Option shall become fully exercisable with respect to the total number of shares
of Optioned Stock, and the Optionee may exercise each Option at any time within
twelve (12) months from the date of termination. To the extent that the Optionee
does not exercise such Option within the time specified herein, the Option shall
terminate.

          (d)  Death of Optionee. In the event of the death of an Optionee (i)
during the term of the Option who is at the time of his death an Employee or
Consultant of the Company or (ii) within six (6) months after the termination of
the employment or consulting relationship, then the exercisability of each
Option granted to such Optionee and outstanding under the Plan shall
automatically accelerate so that each such Option shall become fully exercisable
with respect to the total number of shares of Optioned Stock, and the Option may
be exercised at any time within twelve (12) months following the date of death
by the Optionee's estate or by a person who acquired the right to exercise the
Option by bequest or inheritance.

     10.  Non-Transferability of Options. The Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

     11.  Adjustments Upon Changes in Capitalization or Merger. Subject to any
required action by the shareholders of the Company, the number of shares of
Common Stock covered by each outstanding Option, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options have yet been granted or which have been returned to the Plan
upon cancellation or expiration of any Option, as well as the price per share of
Common Stock covered by each such outstanding Option, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
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,

<PAGE>   4

shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

     In the event of the proposed dissolution or liquidation of the Company, the
Option will terminate immediately prior to the consummation of such proposed
action, unless otherwise provided by the Board. The Board may, in the exercise
of its sole discretion in such instances, declare that any Option shall
terminate as of a date fixed by the Board and give each Optionee the right to
exercise his Option as to all or any part of the Optioned Stock, including
Shares as to which the Option would not otherwise be exercisable. In the event
of the proposed sale of all or substantially all of the equity securities or
assets of the Company, or the merger of the Company with or into another
corporation, the Option shall be assumed or an equivalent option shall be
substituted by such successor corporation, unless the Board determines, in the
exercise of its sole discretion and in lieu of such assumption or substitution,
that the Optionee shall have the right to exercise the Option as to all of the
Optioned Stock, including Shares as to which the Option would not otherwise be
exercisable. If the Board makes an Option fully exercisable in lieu of
assumption or substitution in the event of a merger or sale of securities or
assets, the Board shall notify the Optionee that the Option shall be fully
exercisable for a period of thirty (30) days from the date of such notice, and
the Option will terminate upon the expiration of such period.

     12.  Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date on which the Board makes the determination granting
such Option. Notice of the determination shall be given to each Employee or
Consultant to whom an Option is so granted within a reasonable time after the
date of such grant.

     13.  Amendment and Termination of the Plan. The Board may amend or
terminate the Plan from time to time in such respects as the Board may deem
advisable. Any such amendment or termination of the Plan shall not affect
Options already granted and such Options shall remain in full force and effect
as if the Plan had not been amended or terminated, unless mutually agreed
otherwise between the Optionee and the Board, which agreement must be in writing
and signed by the Optionee and the Company.

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

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

     15.  Reservation of Shares. The Company, during the term of this Plan, will
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     Inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained.

     16.  Option Agreement. Options shall be evidenced by written option
agreements in such form as the Board shall approve.

     17.  Information to Optionees. The Company shall provide to each Optionee,
during the period for which such Optionee has one or more Options outstanding,
copies of all annual reports and other information which are provided to all
shareholders of the Company. The Company shall not be required to provide such
information if the issuance of Options under the Plan is limited to key
employees whose duties in connection with the Company assure their access to
equivalent information.

     18.  CHOICE OF LAW. THE CORPORATE LAW OF THE STATE OF TEXAS WILL GOVERN ALL
QUESTIONS CONCERNING THE RELATIVE RIGHTS OF THE COMPANY AND ITS

<PAGE>   5

SHAREHOLDERS. ALL OTHER QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY AND
INTERPRETATION OF THIS PLAN AND THE INSTRUMENTS EVIDENCING OPTIONS WILL BE
GOVERNED BY THE INTERNAL LAW, AND NOT THE LAW OF CONFLICTS, OF THE STATE OF
TEXAS.

     IN WITNESS WHEREOF, the Company has caused its duly authorized officer to
execute this Plan effective as of the ____ day of ______, 2000.
