                                GLOWBUG.COM, INC.

                      2000 STOCK OPTION/STOCK ISSUANCE PLAN



                         ARTICLE 1. GENERAL PROVISIONS.

      1.1 PURPOSE OF THE PLAN. This 2000 Stock Option/Stock Issuance Plan is
intended to promote the interests of Glowbug.com, Inc., a Delaware corporation,
by providing eligible persons in the Corporation's employ or service with the
opportunity to acquire a proprietary interest, or otherwise increase their
proprietary interest, in the Corporation as an incentive for them to continue in
such employ or service.

   Capitalized terms shall have the meanings assigned to such terms in the
attached Appendix.

      1.2 STRUCTURE OF THE PLAN.

      (a) The Plan shall be divided into two separate equity programs:

            (i) the Option Grant Program under which eligible persons may, at
      the discretion of the Plan Administrator, be granted options to purchase
      shares of Common Stock, and

            (ii) the Stock Issuance Program under which eligible persons may, at
      the discretion of the Plan Administrator, be issued shares of Common Stock
      directly, either through the immediate purchase of such shares or as a
      bonus for services rendered the Corporation (or any Parent or Subsidiary).

      (b) The provisions of Articles 1 and 4 shall apply to both equity programs
under the Plan and shall accordingly govern the interests of all persons under
the Plan.

      1.3 ADMINISTRATION OF THE PLAN.

      (a) The Plan shall be administered by the Board. However, any or all
administrative functions otherwise exercisable by the Board may be delegated to
the Committee. Members of the Committee shall serve for such period of time as
the Board may determine and shall be subject to removal by the Board at any
time. The Board may also at any time terminate the functions of the Committee
and reassume all powers and authority previously delegated to the Committee.

      (b) The Plan Administrator shall have full power and authority (subject to
the provisions of the Plan) to establish such rules and regulations as it may
deem appropriate for proper administration of the Plan and to make such
determinations under, and issue such interpretations of, the Plan and any
outstanding options or stock issuances thereunder as it may deem necessary or
advisable. Decisions of the Plan Administrator shall be final and binding on all
parties who have an interest in the Plan or any option or stock issuance
thereunder.

      1.4 ELIGIBILITY.

      (a) The persons eligible to participate in the Plan are as follows:

            (i) Employees,

            (ii) non-employee members of the Board or the non-employee members
      of the board of directors of any Parent or Subsidiary, and

            (iii) consultants and other independent advisors who provide
      services to the Corporation (or any Parent or Subsidiary).

      (b) The Plan Administrator shall have full authority to determine, (i)
with respect to the grants made under the Option Grant Program, which eligible
persons are to receive the option grants, the time or times when those grants
are to be made, the number of shares to be covered by each such grant, the
status of the granted option as either an Incentive Option or a Non-Statutory
Option, the time or times when each option is to become exercisable, the vesting
schedule (if any) applicable to the option shares and the maximum term for which
the option is to remain outstanding and (ii) with respect to stock issuances
made under the Stock Issuance Program, which eligible persons are to receive
stock issuances, the time or times when those issuances are to be made, the
number of shares to be issued to each Participant, the vesting schedule (if any)
applicable to the issued shares and the consideration to be paid by the
Participant for such shares.

      (c) The Plan Administrator shall have the absolute discretion either to
grant options in accordance with the Option Grant Program or to effect stock
issuances in accordance with the Stock Issuance Program.

      1.5 STOCK SUBJECT TO THE PLAN.

      (a) The stock issuable under the Plan shall be shares of authorized but
unissued or reacquired Common Stock. The maximum number of shares of Common
Stock that may be issued over the term of the Plan shall not exceed 5,000,000
shares.

      (b) Shares of Common Stock subject to outstanding options shall be
available for subsequent issuance under the Plan to the extent (i) the options
expire or terminate for any reason prior to exercise in full or (ii) the options
are canceled in accordance with the cancellation-regrant provisions of Article
2. Unvested shares issued under the Plan and subsequently repurchased by the
Corporation, at the option exercise or direct issue price paid per share,
pursuant to the Corporation's repurchase rights under the Plan shall be added
back to the number of shares of Common Stock reserved for issuance under the
Plan and shall accordingly be available for reissuance through one or more
subsequent option grants or direct stock issuances under the Plan.

      (c) Should any change be made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and/or class of securities issuable under the
Plan and (ii) the number and/or class of securities and the exercise price per
share in effect under each outstanding option to prevent the dilution or
enlargement of benefits thereunder. The adjustments determined by the Plan
Administrator shall be final, binding and conclusive. In no event shall any such

<PAGE>

adjustments be made in connection with the conversion of one or more outstanding
shares of the Corporation's preferred stock into shares of Common Stock.

                        ARTICLE 2. OPTION GRANT PROGRAM.

      2.1 OPTION TERMS. Each option shall be evidenced by one or more documents
in the form approved by the Plan Administrator; PROVIDED, HOWEVER, that each
such document shall comply with the terms specified below. Each document
evidencing an Incentive Option shall, in addition, be subject to the provisions
of the Plan applicable to such options.

      (a) EXERCISE PRICE.

            (i) The exercise price per share shall be fixed by the Plan
      Administrator and may be less than, equal to or greater than the Fair
      Market Value on the option grant date.

            (ii) The exercise price shall become immediately due upon exercise
      of the option and shall, subject to the provisions of Section 4.1 and the
      documents evidencing the option, be payable in cash or check made payable
      to the Corporation. Should the Common Stock be registered under Section 12
      of the 1934 Act at the time the option is exercised, then the exercise
      price may also be paid as follows:

                  a)    in shares of Common Stock held for the requisite period
                        necessary to avoid a charge to the Corporation's
                        earnings for financial reporting purposes and valued at
                        the Fair Market Value on the Exercise Date, or

                  b)    to the extent the option is exercised for vested shares,
                        through a special sale and remittance procedure pursuant
                        to which the Optionee shall concurrently provide
                        irrevocable instructions (a) to a Corporation-designated
                        brokerage firm to effect the immediate sale of the
                        purchased shares and remit to the Corporation, out of
                        the sale proceeds available on the settlement date,
                        sufficient funds to cover the aggregate exercise price
                        payable for the purchased shares plus all applicable
                        Federal, state and local income and employment taxes
                        required to be withheld by the Corporation by reason of
                        such exercise and (b) to the Corporation to deliver the
                        certificates for the purchased shares directly to such
                        brokerage firm to complete the sale.

   Except to the extent such sale and remittance procedure is utilized, payment
of the exercise price for the purchased shares must be made on the Exercise
Date.

      (b) EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable at such
time or times, during such period and for such number of shares as shall be
determined by the Plan Administrator and set forth in the documents evidencing
the option grant. However, no option shall have a term in excess of ten years
measured from the option grant date.

<PAGE>

      (c) EFFECT OF TERMINATION OF SERVICE.

            (i) The following provisions shall govern the exercise of any
      options held by the Optionee at the time of cessation of Service or death:

                  a)    Should the Optionee cease to remain in Service for any
                        reason other than death, Permanent Disability or
                        Misconduct, then the Optionee shall have a period of
                        three months following the date of such cessation of
                        Service during which to exercise each outstanding option
                        held by such Optionee.

                  b)    Should Optionee's Service terminate by reason of
                        Permanent Disability, then the Optionee shall have a
                        period of 12 months following the date of such cessation
                        of Service during which to exercise each outstanding
                        option held by such Optionee.

                  c)    If the Optionee dies while holding an outstanding
                        option, then the personal representative of his or her
                        estate or the person or persons to whom the option is
                        transferred pursuant to the Optionee's will or the laws
                        of inheritance shall have a 12-month period following
                        the date of the Optionee's death to exercise such
                        option.

                  d)    Under no circumstances, however, shall any such option
                        be exercisable after the specified expiration of the
                        option term.

                  e)    During the applicable post-Service exercise period, the
                        option may not be exercised in the aggregate for more
                        than the number of vested shares for which the option is
                        exercisable on the date of the Optionee's cessation of
                        Service. Upon the expiration of the applicable exercise
                        period or (if earlier) upon the expiration of the option
                        term, the option shall terminate and cease to be
                        outstanding for any vested shares for which the option
                        has not been exercised. However, the option shall,
                        immediately upon the Optionee's cessation of Service,
                        terminate and cease to be outstanding with respect to
                        any and all option shares for which the option is not
                        otherwise at the time exercisable or in which the
                        Optionee is not otherwise at that time vested.

                  f)    Should Optionee's Service be terminated for Misconduct,
                        then all outstanding options held by the Optionee shall
                        terminate immediately and cease to remain outstanding.

            (ii) The Plan Administrator shall have the discretion, exercisable
      either at the time an option is granted or at any time while the option
      remains outstanding, to:

                  a)    extend the period of time for which the option is to
                        remain exercisable following the Optionee's cessation of
                        Service or death from the limited period otherwise in
                        effect for that option to such greater period of time as
                        the Plan Administrator shall deem

<PAGE>

                        appropriate, but in no event beyond the expiration of
                        the option term, and/or

                  b)    permit the option to be exercised, during the applicable
                        post-Service exercise period, not only with respect to
                        the number of vested shares of Common Stock for which
                        such option is exercisable at the time of the Optionee's
                        cessation of Service but also with respect to one or
                        more additional installments in which the Optionee would
                        have vested under the option had the Optionee continued
                        in Service.

      (d) STOCKHOLDER RIGHTS. The holder of an option shall have no stockholder
rights with respect to the shares subject to the option until such person shall
have exercised the option, paid the exercise price and become the recordholder
of the purchased shares.

      (e) REPURCHASE RIGHTS. The Plan Administrator shall have the discretion to
grant options that are exercisable for unvested shares of Common Stock. Should
the Optionee cease Service while holding such unvested shares, the Corporation
shall have the right to repurchase, at the exercise price paid per share, any or
all of those unvested shares. The terms upon which such repurchase right shall
be exercisable (including the period and procedure for exercise and the
appropriate vesting schedule for the purchased shares) shall be established by
the Plan Administrator and set forth in the document evidencing such repurchase
right.

      (f) FIRST REFUSAL RIGHTS. Until such time as the Common Stock is first
registered under Section 12 of the 1934 Act, the Corporation shall have the
right of first refusal with respect to any proposed disposition by the Optionee
(or any successor in interest) of any shares of Common Stock issued under the
Option Grant Program. Such right of first refusal shall be exercisable in
accordance with the terms established by the Plan Administrator and set forth in
the document evidencing such right.

      (g) LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of the
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or by the laws of descent
and distribution following the Optionee's death. Non-Statutory Options shall be
subject to the same restrictions, except that a Non-Statutory Option may, to the
extent permitted by the Plan Administrator, be assigned in whole or in part
during the Optionee's lifetime (i) as a gift to one or more members of the
Optionee's immediate family, to a trust in which Optionee and/or one or more
such family members hold more than 50% of the beneficial interest or to an
entity in which more than 50% of the voting interests are owned by one or more
such family members or (ii) pursuant to a domestic relations order. The terms
applicable to the assigned portion shall be the same as those in effect for the
option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Plan Administrator may deem appropriate.

      (h) WITHHOLDING. The Corporation's obligation to deliver shares of Common
Stock upon the exercise of any options granted under the Plan shall be subject
to the satisfaction of all applicable Federal, state and local income and
employment tax withholding requirements.

      2.2 INCENTIVE OPTIONS. The terms specified below shall be applicable to
all Incentive Options. Except as modified by the provisions of this Section 2.2,
all the provisions of Articles 1, 2 and 4 shall be applicable to Incentive
Options. Options that are specifically designated as Non-Statutory Options shall
not be subject to the terms of this Section 2.2.

      (a) ELIGIBILITY. Incentive Options may only be granted to Employees.

<PAGE>

      (b) EXERCISE PRICE. The exercise price per share shall not be less than
100% of the Fair Market Value on the option grant date.

      (c) DOLLAR LIMITATION. The aggregate Fair Market Value (determined as of
the respective date or dates of grant) for which one or more options granted to
any Employee under the Plan (or any other option plan of the Corporation or any
Parent or Subsidiary) may for the first time become exercisable as Incentive
Options during any one calendar year shall not exceed the sum of $100,000. To
the extent the Employee holds two or more such options that become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

      (d) 10% STOCKHOLDER. If any Employee to whom an Incentive Option is
granted is a 10% Stockholder, then the exercise price per share shall not be
less than 110% of the Fair Market Value on the option grant date and the option
term shall not exceed five years measured from the option grant date.

      2.3 CORPORATE TRANSACTION.

      (a) The shares subject to each option outstanding under the Plan at the
time of a Corporate Transaction shall automatically vest in full so that each
such option shall, immediately prior to the effective date of the Corporate
Transaction, become fully exercisable for all of the shares of Common Stock at
the time subject to that option and may be exercised for any or all of those
shares as fully-vested shares of Common Stock. However, the shares subject to an
outstanding option shall NOT vest on such an accelerated basis if and to the
extent: (i) such option is assumed by the successor corporation (or parent
thereof) in the Corporate Transaction and the Corporation's repurchase rights
with respect to the unvested option shares are concurrently assigned to such
successor corporation (or parent thereof) or (ii) such option is to be replaced
with a cash incentive program of the successor corporation that preserves the
spread existing on the unvested option shares at the time of the Corporate
Transaction and provides for subsequent payout in accordance with the same
vesting schedule applicable to those unvested option shares or (iii) the
acceleration of such option is subject to other limitations imposed by the Plan
Administrator at the time of the option grant.

      (b) All outstanding repurchase rights shall also terminate automatically,
and the shares of Common Stock subject to those terminated rights shall
immediately vest in full, in the event of any Corporate Transaction, except to
the extent: (i) those repurchase rights are assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.

      (c) Immediately following the consummation of the Corporate Transaction,
all outstanding options shall terminate and cease to be outstanding, except to
the extent assumed by the successor corporation (or parent thereof).

      (d) Each option that is assumed in connection with a Corporate Transaction
shall be appropriately adjusted, immediately after such Corporate Transaction,
to apply to the number and class of securities that would have been issuable to
the Optionee in consummation of such Corporate Transaction, had the option been
exercised immediately prior to such Corporate Transaction. Appropriate
adjustments shall also be made to (i) the number and class of securities
available for issuance under the Plan following the consummation of such
Corporate Transaction and (ii) the exercise price payable per share under each

<PAGE>

outstanding option, provided the aggregate exercise price payable for such
securities shall remain the same.

      (e) The Plan Administrator shall have the discretion, exercisable either
at the time the option is granted or at any time while the option remains
outstanding, to provide for the automatic acceleration (in whole or in part) of
one or more outstanding options (and the immediate termination of the
Corporation's repurchase rights with respect to the shares subject to those
options) upon the occurrence of a Corporate Transaction, whether or not those
options are to be assumed in the Corporate Transaction.

      (f) The Plan Administrator shall also have full power and authority,
exercisable either at the time the option is granted or at any time while the
option remains outstanding, to structure such option so that the shares subject
to that option will automatically vest on an accelerated basis should the
Optionee's Service terminate by reason of an Involuntary Termination within a
designated period (not to exceed 18 months) following the effective date of any
Corporate Transaction in which the option is assumed and the repurchase rights
applicable to those shares do not otherwise terminate. Any option so accelerated
shall remain exercisable for the fully-vested option shares until the earlier of
(i) the expiration of the option term or (ii) the expiration of the one-year
period measured from the effective date of the Involuntary Termination. In
addition, the Plan Administrator may provide that one or more of the
Corporation's outstanding repurchase rights with respect to shares held by the
Optionee at the time of such Involuntary Termination shall immediately terminate
on an accelerated basis, and the shares subject to those terminated rights shall
accordingly vest at that time.

      (g) The portion of any Incentive Option accelerated in connection with a
Corporate Transaction shall remain exercisable as an Incentive Option only to
the extent the applicable $100,000 limitation is not exceeded. To the extent
such dollar limitation is exceeded, the accelerated portion of such option shall
be exercisable as a Non-Statutory Option under the Federal tax laws.

      (h) The grant of options under the Plan shall in no way affect the right
of the Corporation to adjust, reclassify, reorganize or otherwise change its
capital or business structure or to merge, consolidate, dissolve, liquidate or
sell or transfer all or any part of its business or assets.

      2.4 CANCELLATION AND REGRANT OF OPTIONS. The Plan Administrator shall have
the authority to effect, at any time and from time to time, with the consent of
the affected option holders, the cancellation of any or all outstanding options
under the Option Grant Program and to grant in substitution new options covering
the same or different number of shares of Common Stock but with an exercise
price per share based on the Fair Market Value on the new grant date.

                       ARTICLE 3. STOCK ISSUANCE PROGRAM.

      3.1 STOCK ISSUANCE TERMS. Shares of Common Stock may be issued under the
Stock Issuance Program through direct and immediate issuances without any
intervening option grants. Each such stock issuance shall be evidenced by a
Stock Issuance Agreement that complies with the terms specified below.

      (a) PURCHASE PRICE.

            (i) The purchase price per share shall be fixed by the Plan
      Administrator and may be less than, equal to or greater than the Fair
      Market Value on the issue date.

            (ii) Subject to the provisions of Section 4.1, shares of Common
      Stock may be issued under the Stock Issuance Program for any of the
      following items of

<PAGE>

      consideration that the Plan Administrator may deem appropriate in each
      individual instance:

                  a)    cash or check made payable to the Corporation, or

                  b)    past services rendered to the Corporation (or any Parent
                        or Subsidiary).

      (b) VESTING PROVISIONS.

            (i) Shares of Common Stock issued under the Stock Issuance Program
      may, in the discretion of the Plan Administrator, be fully and immediately
      vested upon issuance or may vest in one or more installments over the
      Participant's period of Service or upon attainment of specified
      performance objectives.

            (ii) Any new, substituted or additional securities or other property
      (including money paid other than as a regular cash dividend) that the
      Participant may have the right to receive with respect to the
      Participant's unvested shares of Common Stock by reason of any stock
      dividend, stock split, recapitalization, combination of shares, exchange
      of shares or other change affecting the outstanding Common Stock as a
      class without the Corporation's receipt of consideration shall be issued
      subject to (i) the same vesting requirements applicable to the
      Participant's unvested shares of Common Stock and (ii) such escrow
      arrangements as the Plan Administrator shall deem appropriate.

            (iii) The Participant shall have full stockholder rights with
      respect to any shares of Common Stock issued to the Participant under the
      Stock Issuance Program, even if the Participant's interest in those shares
      is not vested. Accordingly, the Participant shall have the right to vote
      such shares and to receive any regular cash dividends paid on such shares.

            (iv) Should the Participant cease to remain in Service while holding
      unvested shares of Common Stock issued under the Stock Issuance Program or
      should the performance objectives not be attained with respect to such
      unvested shares of Common Stock, then those shares shall be immediately
      surrendered to the Corporation for cancellation, and the Participant shall
      have no further stockholder rights with respect to those shares. To the
      extent the surrendered shares were previously issued to the Participant
      for consideration paid in cash or cash equivalent (including the
      Participant's purchase-money indebtedness), the Corporation shall repay to
      the Participant the cash consideration paid for the surrendered shares and
      shall cancel the unpaid principal balance of any outstanding
      purchase-money note of the Participant attributable to the surrendered
      shares.

            (v) The Plan Administrator may in its discretion waive the surrender
      and cancellation of one or more unvested shares of Common Stock (or other
      assets attributable thereto) that would otherwise occur upon the
      non-completion of the vesting schedule applicable to such shares. Such
      waiver shall result in the immediate vesting of the Participant's interest
      in the shares of Common Stock as to which the waiver applies. Such waiver
      may be effected at any time, whether before or after the Participant's
      cessation of Service or the attainment or non-attainment of the applicable
      performance objectives.

<PAGE>

      (c) FIRST REFUSAL RIGHTS. Until such time as the Common Stock is first
registered under Section 12 of the 1934 Act, the Corporation shall have the
right of first refusal with respect to any proposed disposition by the
Participant (or any successor in interest) of any shares of Common Stock issued
under the Stock Issuance Program. Such right of first refusal shall be
exercisable in accordance with the terms established by the Plan Administrator
and set forth in the document evidencing such right.

      3.2 CORPORATE TRANSACTION.

      (a) All of the outstanding repurchase rights under the Stock Issuance
Program shall terminate automatically, and all the shares of Common Stock
subject to those terminated rights shall immediately vest in full, in the event
of any Corporate Transaction, except to the extent: (i) those repurchase rights
are assigned to the successor corporation (or parent thereof) in connection with
such Corporate Transaction or (ii) such accelerated vesting is precluded by
other limitations imposed by the Plan Administrator at the time the repurchase
right is issued.

      (b) The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase rights with respect to those shares remain
outstanding, to provide that those rights shall automatically terminate on an
accelerated basis, and the shares of Common Stock subject to those terminated
rights shall immediately vest, in the event the Participant's Service should
subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed 18 months) following the effective date of any
Corporate Transaction in which those repurchase rights are assigned to the
successor corporation (or parent thereof).

      3.3 SHARE ESCROW/LEGENDS. Unvested shares may, in the Plan Administrator's
discretion, be held in escrow by the Corporation until the Participant's
interest in such shares vests or may be issued directly to the Participant with
restrictive legends on the certificates evidencing those unvested shares.

                            ARTICLE 4. MISCELLANEOUS.

      4.1 FINANCING. The Plan Administrator may permit any Optionee or
Participant to pay the option exercise price under the Option Grant Program or
the purchase price for shares issued under the Stock Issuance program by
delivering a full recourse, interest bearing promissory note payable in one or
more installments and secured by the purchased shares. The terms of any such
promissory note (including the interest rate and the terms of repayment) shall
be established by the Plan Administrator in its sole discretion. In no event
shall the maximum credit available to the Optionee or Participant exceed the sum
of (i) the aggregate option exercise price or purchase price payable for the
purchased shares plus (ii) any Federal, state and local income and employment
tax liability incurred by the Optionee or the Participant in connection with the
option exercise or share purchase.

      4.2 EFFECTIVE DATE AND TERM OF THE PLAN.

      (a) The Plan shall become effective when adopted by the Board, but no
option granted under the Plan may be exercised, and no shares shall be issued
under the Plan, until the Plan is approved by the Corporation's stockholders. If
such stockholder approval is not obtained within 12 months after the date of the
Board's adoption of the Plan, then all options previously granted under the Plan
shall terminate and cease to be outstanding, and no further options shall be
granted and no shares shall be issued under the Plan. Subject to such
limitation, the Plan Administrator may grant options and issue shares under the
Plan at any time after the effective date of the Plan and before the date fixed
herein for termination of the Plan.

<PAGE>

      (b) The Plan shall terminate upon the earliest of (i) the expiration of
the ten-year period measured from the date the Plan is adopted by the Board,
(ii) the date on which all shares available for issuance under the Plan shall
have been issued as fully-vested shares or (iii) the termination of all
outstanding options in connection with an Corporate Transaction. All options and
unvested stock issuances outstanding at the time of a clause (i) termination
event shall continue to have full force and effect in accordance with the
provisions of the documents evidencing such options or issuances.

      4.3 AMENDMENT OF THE PLAN.

      (a) The Board shall have complete and exclusive power and authority to
amend or modify the Plan in any or all respects. However, no such amendment or
modification shall adversely affect any rights and obligations with respect to
options or unvested stock issuances at the time outstanding under the Plan,
unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws or regulations.

      (b) Options to purchase shares of Common Stock may be granted under the
Option Grant Program and shares of Common Stock may be issued under the Stock
Issuance Program that are in each instance in excess of the number of shares
then available for issuance under the Plan, provided any excess shares actually
issued under those programs shall be held in escrow until there is obtained
stockholder approval of an amendment sufficiently increasing the number of
shares of Common Stock available for issuance under the Plan. If such
stockholder approval is not obtained within 12 months after the date the first
such excess grants or issuances are made, then (i) any unexercised options
granted on the basis of such excess shares shall terminate and cease to be
outstanding and (ii) the Corporation shall promptly refund to the Optionees and
the Participants the exercise or purchase price paid for any excess shares
issued under the Plan and held in escrow, together with interest (at the
applicable short-term federal rate) for the period the shares were held in
escrow, and such shares shall thereupon be automatically canceled and cease to
be outstanding.

      4.4 USE OF PROCEEDS. Any cash proceeds received by the Corporation from
the sale of shares of Common Stock under the Plan shall be used for general
corporate purposes.

      4.5 WITHHOLDING. The Corporation's obligation to deliver shares of Common
Stock upon the exercise of any options or upon the issuance or vesting of any
shares issued under the Plan shall be subject to the satisfaction of all
applicable Federal, state and local income and employment tax withholding
requirements.

      4.6 GOVERNING LAW. This Plan and the administration thereof shall be
governed by and construed in accordance with the laws of the State of Texas.

      4.7 REGULATORY APPROVALS. The implementation of the Plan, the granting of
any option under the Plan and the issuance of any shares of Common Stock (i)
upon the exercise of any option or (ii) under the Stock Issuance Program shall
be subject to the Corporation's procurement of all approvals and permits
required by regulatory authorities having jurisdiction over the Plan, the
options granted under it and the shares of Common Stock issued pursuant to it.

      4.8 NO EMPLOYMENT OR SERVICE RIGHTS. Nothing in the Plan shall confer upon
the Optionee or the Participant any right to continue in Service for any period
of specific duration or interfere with or otherwise restrict in any way the
rights of the Corporation (or any Parent or Subsidiary employing or

<PAGE>

retaining such person) or of the Optionee or the Participant, which rights are
hereby expressly reserved by each, to terminate such person's Service at any
time for any reason, with or without cause.
