                            1994 INCENTIVE STOCK PLAN

  1.  Purposes of the Plan. The purposes of this Stock Plan are to attract and

granted under the Plan may be incentive stock options (as defined under Section
422 of the Code) or non-statutory stock options, as determined by the
Administrator at the time of grant of an option and subject to the applicable
provisions of Section 422 of the Code, as amended, and the regulations
promulgated thereunder. Stock purchase rights may also be granted under the
Plan.

under the Plan is 4,000,000 shares of Common Stock. The shares may be
authorized, but unissued, or reacquired Common Stock.

  4.  Administration of the Plan.

      (a)  Initial Plan Procedure. Prior to the date, if any, upon which the
Company becomes subject to the Exchange Act, the Plan shall be administered by
the Board or a committee appointed by the Board.

      (b)  Plan Procedure After the Date, if any, upon Which the Company becomes
Subject to the Exchange Act.

           (i)   Administration With Respect to Directors and Officers. With
respect to grants of Options or Stock Purchase Rights to Employees who are also
officers or directors of the Company, the Plan shall be administered by (A) the
Board if the Board may administer the Plan in compliance with Rule 16b-3
promulgated under the Exchange Act or any successor thereto ("Rule 16b-3") with
respect to a plan intended to qualify thereunder as a discretionary plan, or (B)
a committee designated by the Board to administer the Plan, which committee
shall be constituted in such a manner as to permit the Plan to comply with Rule
16b-3 with respect to a plan intended to qualify thereunder as a discretionary
plan. Once appointed, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board. From time to time the Board may
increase the size of the Committee and appoint additional members thereof,
remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies, however caused,

                                       -3-
<PAGE>
and remove all members of the Committee and thereafter directly administer the
Plan, all to the extent permitted by Rule 16b-3 with respect to a plan intended

           (iii) Administration With Respect to Consultants and Other Employees.
With respect to grants of Options or Stock Purchase Rights to Employees or
Consultants who are neither directors nor officers of the Company, the Plan
shall be administered by (A) the Board or (B) a committee designated by the
Board, which committee shall be constituted in such a manner as to satisfy the
legal requirements relating to the administration of incentive stock option
plans, if any, of California corporate and securities laws, of the Code, and of
any applicable stock exchange (the "Applicable Laws"). Once appointed, such
Committee shall continue to serve in its designated capacity until otherwise
directed by the Board. From time to time the Board may increase the size of the
Committee and appoint additional members thereof, remove members (with or
without cause) and appoint new members in substitution therefor, fill vacancies,
however caused, and remove all members of the Committee and thereafter directly
administer the Plan, all to the extent permitted by the Applicable Laws.

      (c)  Powers of the Administrator. Subject to the provisions of the Plan
and, in the case of a Committee, the specific duties delegated by the Board to
such Committee, and subject to the approval of any relevant authorities,
including the approval, if required, of any stock exchange upon which the Common
Stock is listed, the Administrator shall have the authority, in its discretion:

           (i)   to determine the Fair Market Value of the Common Stock, in
accordance with Section 2(k) of the Plan;

           (ii)  to select the Consultants and Employees to whom Options and
Stock Purchase Rights may from time to time be granted hereunder;

           (iii) to determine whether and to what extent Options and Stock
Purchase Rights or any combination thereof are granted hereunder;

           (iv)  to determine the number of shares of Common Stock to be covered
by each such award granted hereunder;

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

           (vi)  to determine the terms and conditions of any award granted
hereunder;

           (vii) to determine whether and under what circumstances an Option may
be settled in cash under subsection 9(f) instead of Common Stock;

                                       -4-
<PAGE>
           (viii) to reduce the exercise price of any Option to the then current
Fair Market Value if the Fair Market Value of the Common Stock covered by such
Option shall have declined since the date the Option was granted;

           (ix)  to determine the terms and restrictions applicable to Stock
Purchase Rights and the Restricted Stock purchased by exercising such Stock
Purchase Rights; and

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

      (d)  Effect of Administrator's Decision. All decisions, determinations and
interpretations of the Administrator shall be final and binding on all Optionees
and any other holders of any Options or Stock Purchase Rights.

  5.  Eligibility.

      (a)  Nonstatutory Stock Options and Stock Purchase Rights may be granted
to Employees and Consultants. Incentive Stock Options may be granted only to
Employees. An Employee or Consultant who has been granted an Option or Stock
Purchase Right may, if otherwise eligible, be granted additional Options or
Stock Purchase Rights.

      (b)  Each Option shall be designated in the written option agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designations, to the extent that the aggregate Fair Market
Value:

           (i)   of Shares subject to an Optionee's Incentive Stock Options
granted by the Company, any Parent or Subsidiary, which

           (ii)  become exercisable for the first time during any calendar year
(under all plans of the Company or any Parent or Subsidiary)

  exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock
Options. For purposes of this Section 5(b), Incentive Stock Options shall be
taken into account in the order in which they were granted, and the Fair Market
Value of the Shares shall be determined as of the time the Option with respect
to such Shares is granted.

      (c)  The Plan shall not confer upon any Optionee any right with respect to
continuation of employment relationship with the Company, nor shall it interfere
in any way with his or her right or the Company's right to terminate his or her
employment relationship at any time, with or without cause.

      (d)  Upon the Company or a successor corporation issuing any class of
common equity securities required to be registered under Section 12 of the
Exchange Act or upon the Plan being assumed by a corporation having a class of
common equity securities required to be registered under Section 12 of the
Exchange Act, the following limitations shall apply to grants of Options and
Stock Purchase Rights to Employees:

                                       -5-
<PAGE>

           (i)  No Employee shall be granted, in any fiscal year of the Company,
Options and Stock Purchase Rights to purchase more than 500,000 Shares.

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

           (iii) If an Option or Stock Purchase Right is canceled 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 canceled Option will be counted
against the limit set forth in Section 5(d)(i). 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.

  6.  Term of Plan. The Plan shall become effective upon the earlier to occur of
its adoption by the Board of Directors or its approval by the shareholders of
the Company, as described in Section 18 of the Plan. It shall continue in effect
for a term of ten (10) years unless sooner terminated under Section 14 of the
Plan.

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

  8.  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 Board, but
shall be subject to the following:

           (i)   In the case of an Incentive Stock Option

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

                 (2) granted to any Employee other than an Employee described in
the preceding paragraph, 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

                 (1) granted to a person who, at the time of the grant of such
Option, owns stock representing more than ten percent (10%) of the voting power

                                       -6-
<PAGE>
of all classes of stock of the Company or any Parent or Subsidiary, the per
Share exercise price shall be no less than 110% of the Fair Market Value per
Share on the date of the grant.

                 (2) granted to any person, the per Share exercise price shall
be no less than 85% of the Fair Market Value per Share on the date of grant.

      (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) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender, and (y) have 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, (5) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and
the broker, if applicable, shall require to effect an exercise of the Option and
delivery to the Company of the sale or loan proceeds required to pay the
exercise price, or (6) any combination of the foregoing methods of payment. In
making its determination as to the type of consideration to accept, the Board
shall consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

  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 and/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 may, as authorized by the Board, consist of any 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 a 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. The Company shall issue (or cause to be issued) such
stock certificate promptly upon 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 12 of the
Plan.

  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.

                                       -7-
<PAGE>
      (b)  Termination of Employment or Consulting Relationship. In the event of
termination of an Optionee's Continuous Status as an Employee or Consultant with
the Company (but not in the event of an Optionee's change of status from
Employee to Consultant (in which case an Employee's Incentive Stock Option shall
automatically convert to a Nonstatutory Stock Option on the ninety-first (91st)
day following such change of status) or from Consultant to Employee), such
Optionee may, but only within such period of time as is determined by the
Administrator, of at least thirty (30) days, with such determination in the case
of an Incentive Stock Option not exceeding three (3) months after the date of
such termination (but in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), exercise his or her Option to
the extent that Optionee was entitled to exercise it at the date of such
termination. To the extent that Optionee was not entitled to exercise the Option
at the date of such termination, or if Optionee does not exercise such Option to
the extent so entitled within the time specified herein, the Option shall
terminate.

      (c)   Disability of Optionee. In the event of termination of an Optionee's
consulting relationship or Continuous Status as an Employee as a result of his
or her disability, Optionee may, but only within six (6) months from the date of
such termination (and in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), exercise the Option to the
extent otherwise entitled to exercise it at the date of such termination;
provided, however, that 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 convert to a Nonstatutory
Stock Option on the day three months and one day following such termination. To
the extent that Optionee was not entitled to exercise the Option at the date of
termination, or if Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

      (d)  Death of Optionee. In the event of the death of an Optionee, the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the expiration of the term of such Option
as set forth in the Notice of Grant), by the Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent that the Optionee was entitled to exercise the Option at the
date of death. 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 immediately revert to the Plan. If, after death, the
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance does not exercise the Option within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

      (e)  Rule 16b-3. Options granted to persons subject to Section 16(b) of
the Exchange Act must comply with Rule 16b-3 and shall contain such additional
conditions or restrictions as may be required thereunder to qualify for the
maximum exemption from Section 16 of the Exchange Act with respect to Plan
transactions.

      (f)  Buyout Provisions. The Administrator may at any time offer to buy out
for a payment in cash or Shares, an Option previously granted, based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.

                                       -8-

  10. Non-Transferability of Options and Stock Purchase Rights. Options and
Stock Purchase Rights 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. Stock Purchase Rights.

      (a)  Rights to Purchase. Stock Purchase Rights may be issued either alone,
in addition to, or in tandem with other awards granted under the Plan and/or
cash awards made outside of the Plan. After the Administrator determines that it
will offer Stock Purchase Rights under the Plan, it shall advise the offeree in
writing of the terms, conditions and restrictions related to the offer,
including the number of Shares that such person shall be entitled to purchase,
the price to be paid, and the time within which such person must accept such
offer, which shall in no event exceed thirty (30) days from the date upon which
the Administrator made the determination to grant the Stock Purchase Right. The
offer shall be accepted by execution of a Restricted Stock purchase agreement in
the form determined by the Administrator. Shares purchased pursuant to the grant
of a Stock Purchase Right shall be referred to herein as "Restricted Stock."

      (b)  Repurchase Option. Unless the Administrator determines otherwise, the
Restricted Stock purchase agreement shall grant the Company a repurchase option
exercisable upon the voluntary or involuntary termination of the purchaser's
employment with the Company for any reason (including death or Disability). The
purchase price for Shares repurchased pursuant to the Restricted Stock purchase
agreement shall be the original price paid by the purchaser and may be paid by
cancellation of any indebtedness of the purchaser to the Company. The repurchase
option shall lapse at such rate as the Administrator may determine, but at a
minimum rate of 20% per year.

      (c)  Other Provisions. The Restricted Stock purchase agreement shall
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion. In
addition, the provisions of Restricted Stock purchase agreements need not be the
same with respect to each purchaser.

      (d)  Rights as a Shareholder. Once the Stock Purchase Right is exercised,
the purchaser shall have the rights equivalent to those of a shareholder, and
shall be a shareholder when his or her purchase is entered upon the records of
the duly authorized transfer agent of the Company. No adjustment will be made
for a dividend or other right for which the record date is prior to the date the
Stock Purchase Right is exercised, except as provided in Section 12 of the Plan.

  12. Adjustments Upon Changes in Capitalization or Merger.

      (a)  Changes in Capitalization. Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each

                                       -9-
<PAGE>
such outstanding Option or Stock Purchase Right, 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,
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 or Stock
Purchase Right.

      (b)  Dissolution or Liquidation. In the event of the proposed dissolution
or liquidation of the Company, the Board shall notify the Optionee at least
fifteen (15) days prior to such proposed action. To the extent it has not been
previously exercised, the Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

      (c)  Merger. In the event of a merger of the Company with or into another
corporation, each outstanding Option or Stock Purchase Right shall be assumed or
an equivalent option or right shall be substituted by such successor corporation
or a parent or subsidiary of such successor corporation. If, in such event, the
Option or Stock Purchase Right is not assumed or substituted, the Option or
Stock Purchase Right shall terminate as of the date of the closing of the
merger. For the purposes of this paragraph, the Option or Stock Purchase Right
shall be considered assumed if, following the merger, the option or right
confers the right to purchase, for each Share of Optioned Stock subject to the
Option or Stock Purchase Right immediately prior to the merger, the
consideration (whether stock, cash, or other securities or property) received in
the merger by holders of Common Stock for each Share held on the effective date
of the transaction (and if 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
was not solely common stock 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 or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, to be solely common stock of the successor corporation or its
Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger.

  13. Time of Granting Options and Stock Purchase Rights. The date of grant of
an Option or Stock Purchase Right shall, for all purposes, be the date on which
the Administrator makes the determination granting such Option or Stock Purchase
Right, or such other date as is determined by the Board. Notice of the
determination shall be given to each Employee or Consultant to whom an Option or
Stock Purchase Right 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 amend, alter,
suspend or discontinue the Plan, but no amendment, alteration, suspension or
discontinuation shall

                                      -10-
<PAGE>
be made which would impair the rights of any Optionee under any grant
theretofore made, without his or her consent. In addition, to the extent
necessary and desirable to comply with Rule 16b-3 under the Exchange Act or with
Section 422 of the Code (or any other applicable law or regulation, including
the requirements of the National Association of Securities Dealers, Inc. or an
established stock exchange), the Company shall obtain shareholder approval of
any Plan amendment in such a manner and to such a degree as required.

      (b)  Effect of Amendment or Termination. Any such amendment or termination
of the Plan shall not affect Options or Stock Purchase Rights already granted,
and such Options and Stock Purchase Rights shall remain in full force and effect
as if this 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.

  15. Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to
the exercise of an Option or Stock Purchase Right unless the exercise of such
Option or Stock Purchase Right 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 Exchange Act,
the rules and regulations promulgated thereunder, 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 or Stock Purchase Right, the
Company may require the person exercising such Option or Stock Purchase Right 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.

  16. 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.

  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. Agreements. Options and Stock Purchase Rights shall be evidenced by
written agreements in such form as the Board shall approve from time to time.

  18. Shareholder Approval. Continuance of the Plan shall be subject to approval
by the shareholders of the Company within twelve (12) months before or after the
date the Plan is adopted. Such shareholder approval shall be obtained in the
degree and manner required under applicable state and federal law and the rules
of any stock exchange upon which the Common Stock is listed.

                                      -11-

  19. Information to Optionees and Purchasers. The Company shall provide to each
Optionee and to each individual who acquired Shares pursuant to the Plan, not
less frequently than annually during the period such Optionee or purchaser has
one or more Options or Stock Purchase Rights outstanding, and, in the case of an
individual who acquired Shares pursuant to the Plan, during the period such
individual owns such Shares, copies of annual financial statements. The Company
shall not be required to provide such statements to key employees whose duties
in connection with the Company assure their access to equivalent information.
