                                       3.
<PAGE>   4
                  (1) To determine from time to time which of the persons
eligible under the Plan shall be granted Stock Awards; when and how each Stock
Award shall be granted; whether a Stock Award will be an Incentive Stock Option,

                  (2) To construe and interpret the Plan and Stock Awards
granted under it, and to establish, amend and revoke rules and regulations for
its administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan or in any Stock Award Agreement,
in a manner and to the extent it shall deem necessary or expedient to make the
Plan fully effective.

                  (3) To amend the Plan or a Stock Award as provided in Section

is delegated to a Committee, the Committee shall have, in connection with the
administration of the Plan, the powers theretofore possessed by the Board,
including the power to delegate to a subcommittee any of the administrative
powers the Committee is authorized to exercise (and references in this Plan to
the Board shall thereafter be to the Committee or such a subcommittee), subject,
however, to such resolutions, not inconsistent with the provisions of the Plan,
as may be adopted from time to time by the Board. The Board may abolish the
Committee at any time and revest in the Board the administration of the Plan.

4.  SHARES SUBJECT TO THE PLAN.

upon changes in stock, the stock that may be issued pursuant to Stock Awards

(or vested in the case of Restricted Stock), the stock not acquired under such
Stock Award shall revert to and again become available for issuance under the
Plan.

         (b) The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.


                                       4.

5. ELIGIBILITY.

         (a) Incentive Stock Options may be granted only to Employees. Stock
Awards other than Incentive Stock Options may be granted only to Employees,
Directors or Consultants.

         (b) No person shall be eligible for the grant of an Incentive Stock
Option if, at the time of grant, such person owns (or is deemed to own pursuant
to Section 424(d) of the Code) stock possessing more than ten percent (10%) of
the total combined voting power of all classes of stock of the Company or of any
of its Affiliates unless the exercise price of such Option is at least one
hundred ten percent (110%) of the Fair Market Value of such stock at the date of
grant and the Option is not exercisable after the expiration of five (5) years
from the date of grant.

         (c) Subject to the provisions of Section 12 relating to adjustments
upon changes in stock, no person shall be eligible to be granted Stock Awards
covering more than four hundred thousand (400,000) shares of Common Stock in any
calendar year.

6. OPTION PROVISIONS.

         Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

         (a) TERM. No Option shall be exercisable after the expiration of ten
(10) years from the date it was granted.

         (b) PRICE. The exercise price of each Incentive Stock Option shall be
not less than one hundred percent (100%) of the Fair Market Value of the stock
subject to the Option on the date the Option is granted, and the exercise price
of each Nonstatutory Stock Option shall be not less than eighty-five percent
(85%) of the Fair Market Value of the stock subject to the Option on the date
the Option is granted. Notwithstanding the foregoing, an Option may be granted
with an exercise price lower than that set forth in the preceding sentence if
such Option is granted pursuant to an assumption or substitution for another
Option in a manner satisfying the provisions of Section 424(a) of the Code.

         (c) CONSIDERATION. The purchase price of stock acquired pursuant to an
Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, or (ii) at
the discretion of the Board or Committee, at the time of the grant of the
Option, (A) by delivery to the Company of other Common Stock of the Company, (B)
according to a deferred payment or other arrangement (which may include, without
limiting the generality of the foregoing, the use of other Common Stock of the
Company) with the person to whom the Option is granted or to whom the Option is
transferred pursuant to subsection 6(d), or (C) in any other form of legal
consideration that may be acceptable to the Board. In the case of any deferred
payment arrangement, interest shall be payable at least annually and shall be
charged at the minimum rate of interest necessary to avoid

                                       5.
<PAGE>   6
the treatment as interest, under any applicable provisions of the Code, of any
amounts other than amounts stated to be interest under the deferred payment
arrangement.

         (d) TRANSFERABILITY. An Incentive Stock Option shall not be
transferable except by will or by the laws of descent and distribution, and
shall be exercisable during the lifetime of the person to whom the Incentive
Stock Option is granted only by such person. A Nonstatutory Stock Option may be
transferred to the extent provided in the Option Agreement; provided that if the
Option Agreement does not expressly permit the transfer of a Nonstatutory Stock
Option, the Nonstatutory Stock Option shall not be transferable except by will,
by the laws of descent and distribution or pursuant to a domestic relations
order satisfying the requirements of Rule 16b-3, and shall be exercisable during
the lifetime of the person to whom the Option is granted only by such person or
any transferee pursuant to a domestic relations order. Notwithstanding the
foregoing, the person to whom the Option is granted may, by delivering written
notice to the Company, in a form satisfactory to the Company, designate a third
party who, in the event of the death of the Optionee, shall thereafter be
entitled to exercise the Option.

         (e) VESTING. The total number of shares of stock subject to an Option
may, but need not, be allotted in periodic installments (which may, but need
not, be equal). The Option Agreement may provide that from time to time during
each of such installment periods, the Option may become exercisable ("vest")
with respect to some or all of the shares allotted to that period, and may be
exercised with respect to some or all of the shares allotted to such period
and/or any prior period as to which the Option became vested but was not fully
exercised. The Option may be subject to such other terms and conditions on the
time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate. The provisions of this
subsection 6(e) are subject to any Option provisions governing the minimum
number of shares as to which an Option may be exercised.

         (f) TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR
CONSULTANT. In the event an Optionee's Continuous Status as an Employee,
Director or Consultant terminates (other than upon the Optionee's death or
disability), the Optionee may exercise his or her Option within such period of
time designated by the Board, which shall in no event be later than the
expiration of the term of the Option as set forth in the Option Agreement (the
"Post-Termination Exercise Period") and only to the extent that the Optionee was
entitled to exercise the Option on the date Optionee's Continuous Status as an
Employee, Director or Consultant terminates. In the case of an Incentive Stock
Option, the Board shall determine the Post-Termination Exercise Period at the
time the Option is granted, and the term of such Post-Termination Exercise
Period shall in no event exceed three (3) months from the date of termination,
and may, in the event Optionee's Continuous Status as an Employee, Director or
Consultant terminates for Cause (as defined in subsection 12(b)), terminate of
the date of such Optionee's termination. In addition, the Board may at any time,
with the consent of the Optionee, extend the Post-Termination Exercise Period
and provide for continued vesting; provided however, that any extension of such
period by the Board in excess of three (3) months from the date of termination
shall cause an Incentive Stock Option so extended to become a Nonstatutory Stock
Option, effective as of the date of Board action. If, at the date of
termination, the Optionee is not entitled to exercise his or her entire Option,
the shares covered by the unexercisable portion of the Option shall revert to
the Plan. If, after termination, the Optionee does not exercise his

                                       6.
<PAGE>   7
or her Option within the time specified in the Option Agreement or as otherwise
determined above, the Option shall terminate, and the shares covered by such
Option shall revert to the Plan. Notwithstanding the foregoing, the Board shall
have the power to permit an Option to continue to vest during the
Post-Termination Exercise Period.

         An Optionee's Option Agreement may also provide that if the exercise of
the Option following the termination of the Optionee's Continuous Status as an
Employee, Director, or Consultant (other than upon the Optionee's death or
disability) would result in liability under Section 16(b) of the Exchange Act,
then the Option shall terminate on the earlier of (i) the expiration of the term
of the Option set forth in the Option Agreement, or (ii) the tenth (10th) day
after the last date on which such exercise would result in such liability under
Section 16(b) of the Exchange Act. Finally, an Optionee's Option Agreement may
also provide that if the exercise of the Option following the termination of the
Optionee's Continuous Status as an Employee, Director or Consultant (other than
upon the Optionee's death or disability) would be prohibited at any time solely
because the issuance of shares would violate the registration requirements under
the Securities Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in the first paragraph of this
subsection 6(f), or (ii) the expiration of a period of three (3) months after
the termination of the Optionee's Continuous Status as an Employee, Director or
Consultant during which the exercise of the Option would not be in violation of
such registration requirements.

         (g) DISABILITY OF OPTIONEE. In the event an Optionee's Continuous
Status as an Employee, Director or Consultant terminates as a result of the
Optionee's disability, the Optionee may exercise his or her Option (to the
extent that the Optionee was entitled to exercise it at the date of
termination), but only within such period of time ending on the earlier of (i)
the date twelve (12) months following such termination (or such longer or
shorter period specified in the Option Agreement), or (ii) the expiration of the
term of the Option as set forth in the Option Agreement. If, at the date of
termination, the Optionee is not entitled to exercise his or her entire Option,
the shares covered by the unexercisable portion of the Option shall revert to
and again become available for issuance under the Plan. If, after termination,
the Optionee does not exercise his or her Option within the time specified
herein, the Option shall terminate, and the shares covered by such Option shall
revert to and again become available for issuance under the Plan.

         (h) DEATH OF OPTIONEE. In the event of the death of an Optionee during,
or within a three (3)-month period after the termination of, the Optionee's
Continuous Status as an Employee, Director or Consultant, the Option may be
exercised to the extent vested by the Optionee's estate, by a person who
acquired the right to exercise the Option by bequest or inheritance or by a
person designated to exercise the option upon the Optionee's death pursuant to
subsection 6(d), but only within the period ending on the earlier of (i) the
date eighteen (18) months following the date of death (or such longer or shorter
period specified in the Option Agreement), or (ii) the expiration of the term of
such Option as set forth in the Option Agreement. If, at the time of death, the
Optionee was not entitled to exercise his or her entire Option, the shares
covered by the unexercisable portion of the Option shall revert to and again
become available for issuance under the Plan. If, after death, the Option is not
exercised within

                                       7.
<PAGE>   8
the time specified herein, the Option shall terminate, and the shares covered by
such Option shall revert to and again become available for issuance under the
Plan.

         (i) EARLY EXERCISE. The Option may, but need not, include a provision
whereby the Optionee may elect at any time while an Employee, Director or
Consultant to exercise the Option as to any part or all of the shares subject to
the Option prior to the full vesting of the Option. Any unvested shares so
purchased may be subject to a repurchase right in favor of the Company or to any
other restriction the Board determines to be appropriate.

         (j) RE-LOAD OPTIONS. Without in any way limiting the authority of the
Board or Committee to make or not to make grants of Options hereunder, the Board
or Committee shall have the authority (but not an obligation) to include as part
of any Option Agreement a provision entitling the Optionee to a further Option
(a "Re-Load Option") in the event the Optionee exercises the Option evidenced by
the Option Agreement, in whole or in part, by surrendering other shares of
Common Stock in accordance with this Plan and the terms and conditions of the
Option Agreement. Any such Re-Load Option (i) shall be for a number of shares
equal to the number of shares surrendered as part or all of the exercise price
of such Option; (ii) shall have an expiration date which is the same as the
expiration date of the Option the exercise of which gave rise to such Re-Load
Option; and (iii) shall have an exercise price which is equal to one hundred
percent (100%) of the Fair Market Value of the Common Stock subject to the
Re-Load Option on the date of exercise of the original Option. Notwithstanding
the foregoing, a Re-Load Option which is an Incentive Stock Option and which is
granted to a 10% stockholder (as described in subsection 5(b)), shall have an
exercise price which is equal to one hundred ten percent (110%) of the Fair
Market Value of the stock subject to the Re-Load Option on the date of exercise
of the original Option and shall have a term which is no longer than five (5)
years.

         Any such Re-Load Option may be an Incentive Stock Option or a
Nonstatutory Stock Option, as the Board or Committee may designate at the time
of the grant of the original Option; provided, however, that the designation of
any Re-Load Option as an Incentive Stock Option shall be subject to the one
hundred thousand dollars ($100,000) annual limitation on exercisability of
Incentive Stock Options described in subsection 11(d) of the Plan and in Section
422(d) of the Code. There shall be no Re-Load Options on a Re-Load Option. Any
such Re-Load Option shall be subject to the availability of sufficient shares
under subsection 4(a) and shall be subject to such other terms and conditions as
the Board or Committee may determine which are not inconsistent with the express
provisions of the Plan regarding the terms of Options.

7. TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

         Each stock bonus or restricted stock purchase agreement shall be in
such form and shall contain such terms and conditions as the Board or Committee
shall deem appropriate. The terms and conditions of stock bonus or restricted
stock purchase agreements may change from time to time, and the terms and
conditions of separate agreements need not be identical, but each stock bonus or
restricted stock purchase agreement shall include (through incorporation of
provisions hereof by reference in the agreement or otherwise) the substance of
each of the following provisions as appropriate:

                                       8.
<PAGE>   9
         (a) PURCHASE PRICE. The purchase price under each restricted stock
purchase agreement shall be such amount as the Board or Committee shall
determine and designate in such agreement but in no event shall the purchase
price be less than eighty-five percent (85%) of the stock's Fair Market Value on
the date such award is made. Notwithstanding the foregoing, the Board or
Committee may determine that eligible participants in the Plan may be awarded
stock pursuant to a stock bonus agreement in consideration for past services
actually rendered to the Company for its benefit.

         (b) TRANSFERABILITY. No rights under a stock bonus or restricted stock
purchase agreement shall be transferable except by will or the laws of descent
and distribution or, if the agreement so provides, pursuant to a domestic
relations order satisfying the requirements of Rule 16b-3, so long as stock
awarded under such agreement remains subject to the terms of the agreement.

         (c) CONSIDERATION. The purchase price of stock acquired pursuant to a
stock purchase agreement shall be paid either: (i) in cash at the time of
purchase; (ii) at the discretion of the Board or Committee, according to a
deferred payment or other arrangement with the person to whom the stock is sold;
or (iii) in any other form of legal consideration that may be acceptable to the
Board or Committee in its discretion. Notwithstanding the foregoing, the Board
or Committee to which administration of the Plan has been delegated may award
stock pursuant to a stock bonus agreement in consideration for past services
actually rendered to the Company or for its benefit.

         (d) VESTING. Shares of stock sold or awarded under the Plan may, but
need not, be subject to a repurchase option in favor of the Company in
accordance with a vesting schedule to be determined by the Board or Committee.

         (e) TERMINATION OF CONTINUOUS STATUS AS AN EMPLOYEE, DIRECTOR OR
CONSULTANT. In the event a Participant's Continuous Status as an Employee,
Director or Consultant terminates, the Company may repurchase or otherwise
reacquire any or all of the shares of stock held by that person which have not
vested as of the date of termination under the terms of the stock bonus or
restricted stock purchase agreement between the Company and such person.

8. CANCELLATION AND RE-GRANT OF OPTIONS.

         (a) The Board or Committee shall have the authority to effect, at any
time and from time to time, (i) the repricing of any outstanding Options under
the Plan and/or (ii) with the consent of any adversely affected holders of
Options, the cancellation of any outstanding Options under the Plan and the
grant in substitution therefor of new Options under the Plan covering the same
or different numbers of shares of stock, but having an exercise price per share
not less than: eighty-five percent (85%) of the Fair Market Value for a
Nonstatutory Stock Option, one hundred percent (100%) of the Fair Market Value
in the case of an Incentive Stock Option or, in the case of an Incentive Stock
Option held by a 10% stockholder (as described in subsection 5(b)), not less
than one hundred ten percent (110%) of the Fair Market Value per share of stock
on the new grant date. Notwithstanding the foregoing, the Board or Committee may
grant an

                                       9.
<PAGE>   10
Option with an exercise price lower than that set forth above if such Option is
granted as part of a transaction to which section 424(a) of the Code applies.

         (b) Shares subject to an Option canceled under this Section 8 shall
continue to be counted against the maximum award of Options permitted to be
granted pursuant to the Plan. The repricing of an Option hereunder resulting in
a reduction of the exercise price, shall be deemed to be a cancellation of the
original Option and the grant of a substitute Option; in the event of such
repricing, both the original and the substituted Options shall be counted
against the maximum awards of Options permitted to be granted pursuant to the
Plan, to the extent required by Section 162(m) of the Code.

9. COVENANTS OF THE COMPANY.

         (a) During the terms of the Stock Awards, the Company shall keep
available at all times the number of shares of stock required to satisfy such
Stock Awards.

         (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares under Stock Awards; provided, however, that this
undertaking shall not require the Company to register under the Securities Act
of 1933, as amended (the "Securities Act") either the Plan, any Stock Award or
any stock issued or issuable pursuant to any such Stock Award. If, after
reasonable efforts, the Company is unable to obtain from any such regulatory
commission or agency the authority which counsel for the Company deems necessary
for the lawful issuance and sale of stock under the Plan, the Company shall be
relieved from any liability for failure to issue and sell stock upon exercise of
such Stock Awards unless and until such authority is obtained.

10. USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock pursuant to Stock Awards shall
constitute general funds of the Company.

11. MISCELLANEOUS.

         (a) The Board shall have the power to accelerate the time at which a
Stock Award may first be exercised or the time during which a Stock Award or any
part thereof will vest, notwithstanding the provisions in the Stock Award
stating the time at which it may first be exercised or the time during which it
will vest.

         (b) Neither an Employee, Director nor a Consultant nor any person to
whom a Stock Award is transferred in accordance with the Plan shall be deemed to
be the holder of, or to have any of the rights of a holder with respect to, any
shares subject to such Stock Award unless and until such person has satisfied
all requirements for exercise of the Stock Award pursuant to its terms.


                                       10.
<PAGE>   11
         (c) Nothing in the Plan or any instrument executed or Stock Award
granted pursuant thereto shall confer upon any Employee, Consultant or other
holder of Stock Awards any right to continue in the employ of the Company or any
Affiliate, or to continue serving as a Consultant and Director, or shall affect
the right of the Company or any Affiliate to terminate the employment of any
Employee with or without notice and with or without cause, or the right to
terminate the relationship of any Consultant pursuant to the terms of such
Consultant's agreement with the Company or Affiliate or service as a Director
pursuant to the Company's By-Laws.

         (d) To the extent that the aggregate Fair Market Value (determined at
the time of grant) of stock with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year under
all plans of the Company and its Affiliates exceeds one hundred thousand dollars
($100,000), the Options or portions thereof which exceed such limit (according
to the order in which they were granted) shall be treated as Nonstatutory Stock
Options.

         (e) The Company may require any person to whom a Stock Award is
granted, or any person to whom a Stock Award is transferred in accordance with
the Plan, as a condition of exercising or acquiring stock under any Stock Award,
(1) to give written assurances satisfactory to the Company as to such person's
knowledge and experience in financial and business matters and/or to employ a
purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters, and that he or
she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award; and (2) to
give written assurances satisfactory to the Company stating that such person is
acquiring the stock subject to the Stock Award for such person's own account and
not with any present intention of selling or otherwise distributing the stock.
The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (i) the issuance of the shares upon the
exercise or acquisition of stock under the Stock Award has been registered under
a then currently effective registration statement under the Securities Act, or
(ii) as to any particular requirement, a determination is made by counsel for
the Company that such requirement need not be met in the circumstances under the
then applicable securities laws. The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such
counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of the stock.

         (f) To the extent provided by the terms of a Stock Award Agreement, the
person to whom a Stock Award is granted may satisfy any federal, state or local
tax withholding obligation relating to the exercise or acquisition of stock
under a Stock Award by any of the following means or by a combination of such
means: (1) tendering a cash payment; (2) authorizing the Company to withhold
shares from the shares of the Common Stock otherwise issuable to the participant
as a result of the exercise or acquisition of stock under the Stock Award; or
(3) delivering to the Company owned and unencumbered shares of the Common Stock
of the Company.

12. ADJUSTMENTS UPON CHANGES IN STOCK.

         (a) If any change is made in the stock subject to the Plan, or subject
to any Stock Award, without the receipt of consideration by the Company (through
merger, consolidation, reorganization, recapitalization, reincorporation, stock
dividend, dividend in property other than cash, stock split, liquidating
dividend, combination of shares, exchange of shares, change in corporate
structure or other transaction not involving the receipt of consideration by the
Company), the Plan will be appropriately adjusted in the class(es) and maximum
number of shares subject to the Plan and the maximum number of shares subject to
award to any person during any calendar year, and the outstanding Stock Awards
will be appropriately adjusted in the class(es) and number of shares and price
per share of stock subject to such outstanding Stock Awards. Such adjustments
shall be made by the Board or Committee, the determination of which shall be
final, binding and conclusive. (The conversion of any convertible securities of
the Company shall not be treated as a "transaction not involving the receipt of
consideration by the Company.")

         (b) In the event of a Change in Control, (i) any surviving or acquiring
corporation shall assume Stock Awards outstanding under the Plan or shall
substitute similar Stock Awards for those outstanding under the Plan, or (ii) in
the event any surviving or acquiring corporation refuses to assume such Stock
Awards or to substitute similar Stock Awards for those outstanding under the
Plan, (A) with respect to Stock Awards held by persons then performing services
as Employees, Directors or Consultants, the vesting of such Stock Awards and the
time during which such Stock Awards may be exercised shall be accelerated prior
to such event and the Stock Awards terminated if not exercised after such
acceleration and at or prior to such event, and (B) with respect to any other
Stock Awards outstanding under the Plan, such Stock Awards shall be terminated
if not exercised prior to such event.

         In addition, with respect to any person who was providing services as
an Employee, Director or Consultant immediately prior to the consummation of the
Change in Control, any Stock Awards held by such persons shall immediately
become fully vested and exercisable, and any repurchase right by the Company
with respect to shares acquired by such person under a Stock Award shall lapse,
if such person's Continuous Status as an Employee, Director or Consultant is
terminated other than for Cause within twelve (12) months following consummation
of the Change in Control. For purposes of the Plan, "Cause" shall mean willful
conduct that is materially injurious to the business of the person's employer,
whether financial or otherwise.

         For purposes of this Plan, "Change in Control" means: (1) a
dissolution, liquidation, or sale of all or substantially all of the assets of
the Company; (2) a merger or consolidation in which the Company is not the
surviving corporation; (3) a reverse merger in which the Company is the
surviving corporation but the shares of the Company's common shares outstanding
immediately preceding the merger are converted by virtue of the merger into
other property, whether in the form of securities, cash or otherwise; or (4) the
acquisition by any person, entity or group within the meaning of Section 13(d)
or 14(d) of the Exchange Act, or any comparable successor provisions (excluding
any employee benefit plan, or related trust, sponsored or maintained by the
Company or any Affiliate of the Company) of the beneficial ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable
successor rule)

                                       12.

of securities of the Company representing at least fifty percent (50%) of the
combined voting power entitled to vote in the election of directors.

13. AMENDMENT OF THE PLAN AND STOCK AWARDS.

         (a) The Board at any time, and from time to time, may amend the Plan.
However, except as provided in Section 12 relating to adjustments upon changes
in stock, no amendment shall be effective unless approved by the stockholders of
the Company to the extent stockholder approval is necessary for the Plan to
satisfy the requirements of Section 422 of the Code, Rule 16b-3 or any Nasdaq or
securities exchange listing requirements.

         (b) The Board may in its sole discretion submit any other amendment to
the Plan for stockholder approval, including, but not limited to, amendments to
the Plan intended to satisfy the requirements of Section 162(m) of the Code and
the regulations thereunder regarding the exclusion of performance-based
compensation from the limit on corporate deductibility of compensation paid to
certain executive officers.

         (c) It is expressly contemplated that the Board may amend the Plan in
any respect the Board deems necessary or advisable to provide eligible
Employees, Directors or Consultants with the maximum benefits provided or to be
provided under the provisions of the Code and the regulations promulgated
thereunder relating to Incentive Stock Options and/or to bring the Plan and/or
Incentive Stock Options granted under it into compliance therewith.

         (d) Rights and obligations under any Stock Award granted before
amendment of the Plan shall not be impaired by any amendment of the Plan unless
(i) the Company requests the consent of the person to whom the Stock Award was
granted and (ii) such person consents in writing.

         (e) The Board at any time, and from time to time, may amend the terms
of any one or more Stock Award; provided, however, that the rights and
obligations under any Stock Award shall not be impaired by any such amendment
unless (i) the Company requests the consent of the person to whom the Stock
Award was granted and (ii) such person consents in writing.

14.  TERMINATION OR SUSPENSION OF THE PLAN.

         (a) The Board may suspend or terminate the Plan at any time. Unless
sooner terminated, the Plan shall terminate ten (10) years from the date the
Plan is adopted by the Board or approved by the stockholders of the Company,
whichever is earlier. No Stock Awards may be granted under the Plan while the
Plan is suspended or after it is terminated.

         (b) Rights and obligations under any Stock Award granted while the Plan
is in effect shall not be impaired by suspension or termination of the Plan,
except with the consent of the person to whom the Stock Award was granted.

<PAGE>   14
15.  EFFECTIVE DATE OF PLAN.

         This Plan shall become effective on the date of adoption by the Board,
but no Stock Awards granted under the Plan shall be exercised unless and until
the Plan has been approved by the stockholders of the Company, which approval
shall be within twelve (12) months before or after the date the Plan is adopted
by the Board.

                             STOCK OPTION AGREEMENT


         Pursuant to the Grant Notice and this Stock Option Agreement, the
Company has granted you an option to purchase the number of shares of the
Company's common stock ("Common Stock") indicated in the Grant Notice at the
exercise price indicated in the Grant Notice. Defined terms not explicitly
defined in this Stock Option Agreement but defined in the Plan shall have the
same definitions as in the Plan.

         The details of your option are as follows:

         1. VESTING. Subject to the limitations contained herein, your option
will vest as provided in the Grant Notice, provided that vesting will cease upon
the termination of your Continuous Status as an Employee, Director or
Consultant.

         2. METHOD OF PAYMENT.

                  (a) PAYMENT OPTIONS. Payment of the exercise price by cash or
check is due in full upon exercise of all or any part of your option, provided
that you may elect, to the extent permitted by applicable law and the Grant
Notice, to make payment of the exercise price under one of the following
alternatives:

                                  (i) Payment pursuant to a program developed
under Regulation T as promulgated by the Federal Reserve Board which, prior to
the issuance of Common Stock, results in either the receipt of cash (or check)
by the Company or the receipt of irrevocable instructions to pay the aggregate
exercise price to the Company from the sales proceeds;

                                  (ii) Provided that at the time of exercise the
Company's Common Stock is publicly traded and quoted regularly in the Wall
Street Journal, payment by delivery of already-owned shares of Common Stock,
held for the period required to avoid a charge to the Company's reported
earnings, and owned free and clear of any liens, claims, encumbrances or
security interests, which Common Stock shall be valued at its fair market value
on the date of exercise; or

                                  (iii) Payment by a combination of the above
methods.

         3. WHOLE SHARES. Your option may only be exercised for whole shares.

         4. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, your option may not be exercised unless the shares issuable
upon exercise of your option are then registered under the Securities Act or, if
such shares are not then so registered, the Company has determined that such
exercise and issuance would be exempt from the registration requirements of the
Securities Act.
<PAGE>   17
         5. TERM. The term of your option commences on the Date of Grant and
expires upon the earliest of:

                                  (i) the Expiration Date indicated in the Grant
Notice;

                                  (ii) the tenth (10th) anniversary of the Date
of Grant;

                                  (iii) eighteen (18) months after your death,
if you die during, or within three (3) months after the termination of your
Continuous Status as Employee, Director or Consultant;

                                  (iv) twelve (12) months after the termination
of your Continuous Status as Employee, Director or Consultant due to disability;

                                  (v) immediately after the termination of your
Continuous Status as Employee, Director or Consultant for Cause; or

                                  (vi) three (3) months after the termination of
your Continuous Status as an Employee, Director or Consultant for any other
reason, provided that if during any part of such three (3)-month period the
option is not exercisable solely because of the condition set forth in paragraph
4 (Securities Law Compliance), in which event the option shall not expire until
the earlier of the Expiration Date or until it shall have been exercisable for
an aggregate period of three (3) months after the termination of Continuous
Status as an Employee, Director or Consultant.

                  For these purposes, "Cause" shall include, but not be limited
to, the commission of any act of fraud, embezzlement or dishonesty, any
unauthorized use or disclosure of confidential information or trade secrets of
the Company, or any other intentional misconduct adversely affecting the
business or affairs of the Company in a material manner. The foregoing
definition shall not be deemed to be inclusive of all the acts or omissions
which the Company may consider as ground for your dismissal or discharge.

                  To obtain the federal income tax advantages associated with an
"incentive stock option," the Code requires that at all times beginning on the
grant date of the option and ending on the day three (3) months before the date
of the option's exercise, you must be an employee of the Company, except in the
event of your death or permanent and total disability. The Company cannot
guarantee that your option will be treated as an "incentive stock option" if you
exercise your option more than three (3) months after the date your employment
with the Company terminates.

         6. EXERCISE.

                  (a) You may exercise the vested portion of your option during
its term (and the unvested portion of your option if the Grant Notice so
permits) by delivering a notice of exercise (in a form designated by the
Company) together with the exercise price to the Secretary of the

                                       2.
<PAGE>   18
Company, or to such other person as the Company may designate, during regular
business hours, together with such additional documents as the Company may then
require.

                  (b)  By exercising your option you agree that:

                                  (i) as a condition to any exercise of your
option, the Company may require you to enter an arrangement providing for the
payment by you to the Company of any tax withholding obligation of the Company
arising by reason of (1) the exercise of your option; (2) the lapse of any
substantial risk of forfeiture to which the shares are subject at the time of
exercise; or (3) the disposition of shares acquired upon such exercise;

                                  (ii) you will notify the Company in writing
within fifteen (15) days after the date of any disposition of any of the shares
of the Common Stock issued upon exercise of an incentive stock option that
occurs within two (2) years after the Date of Grant or within one (1) year after
such shares of Common Stock are transferred upon exercise of your option; and

                                  (iii) the Company (or a representative of the
underwriters) may, in connection with the first underwritten registration of the
offering of any securities of the Company under the Act, require that you not
sell or otherwise transfer or dispose of any shares of Common Stock or other
securities of the Company during such period (not to exceed one hundred eighty
(180) days) following the effective date of the registration statement of the
Company filed under the Act as may be requested by the Company or the
representative of the underwriters. You further agree that the Company may
impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such period.

         7. TRANSFERABILITY. Your option is not transferable, except by will or
by the laws of descent and distribution, and is exercisable during your life
only by you. Notwithstanding the foregoing, by delivering written notice to the
Company, in a form satisfactory to the Company, you may designate a third party
who, in the event of your death, shall thereafter be entitled to exercise your
option.

         8. OPTION NOT A SERVICE CONTRACT. Your option is not an employment
contract and nothing in your option shall be deemed to create in any way
whatsoever any obligation on your part to continue in the employ of the Company,
or of the Company to continue your employment with the Company. In addition,
nothing in your option shall obligate the Company, its shareholders, board of
directors, officers or employees to continue any relationship which you might
have as a director or consultant for the Company.

         9. NOTICES. Any notices provided for in your option or the Plan shall
be given in writing and shall be deemed effectively given upon receipt or, in
the case of notices delivered by the Company to you, five (5) days after deposit
in the United States mail, postage prepaid, addressed to you at the last address
you provided to the Company.

         10. GOVERNING PLAN DOCUMENT. Your option is subject to all the
provisions of the Plan, the provisions of which are hereby made a part of your
option, including without

                                       3.
<PAGE>   19
limitation the provisions of the Plan relating to option provisions, and is
further subject to all interpretations, amendments, rules and regulations which
may from time to time be promulgated and adopted pursuant to the Plan. In the
event of any conflict between the provisions of your option and those of the
Plan, the provisions of the Plan shall control.


                                       4.
