                               1996 ISO STOCK PLAN

     1. Purposes of the Plan. The purposes of this Stock Plan are to attract and
retain the best available personnel for positions of substantial responsibility,
to provide additional incentive to Employees and Consultants of the Company and
its Subsidiaries and to promote the success of the Company's business. Options
granted under the Plan may be Incentive Stock Options or Nonstatutory 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 and the
regulations promulgated thereunder. Stock Purchase Rights may also be granted
under the Plan.

     3. Stock Subject to the Plan. Subject to the provisions of Section 12 of
the Plan, the maximum aggregate number of Shares which may be subject to option
and sold under the Plan is 9,816,586 Shares plus an annual increase to be added

lesser of (i) 2,000,000 shares, (ii) 5% of the outstanding shares on such date
or (iii) an amount determined by the Administrator. The Shares may be authorized
but unissued, or reacquired Common Stock.

     If an Option or Stock Purchase Right expires or becomes unexercisable
without having been exercised in full, or is surrendered pursuant to an option
exchange program, the unpurchased Shares which were subject thereto shall become
available for future grant or sale under the Plan (unless the Plan has
terminated). However, Shares that have actually been issued under the Plan, upon
exercise of either an Option or Stock Purchase Right, shall not be returned to
the Plan and shall not become available for future distribution under the Plan,
except that if Shares of Restricted Stock are repurchased by the Company at
their original purchase price, and the original purchaser of such Shares did not
receive any benefits of ownership of such Shares, such Shares shall become
available


                                       3
<PAGE>

for future grant under the Plan. For purposes of the preceding sentence, voting
rights shall not be considered a benefit of Share ownership.

     4. Administration of the Plan.

        (a) Procedure.

            (i) Multiple Administrative Bodies. Different Committees with
respect to different groups of Service Providers may administer the Plan.

            (ii) Section 162(m). To the extent that the Administrator determines
it to be desirable to qualify Options granted hereunder as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the Plan shall
be administered by a Committee of two or more "outside directors" within the
meaning of Section 162(m) of the Code.

            (iii) Rule 16b-3. To the extent desirable to qualify transactions
hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder
shall be structured to satisfy the requirements for exemption under Rule 16b-3.

            (iv) Other Administration. Other than as provided above, the Plan
shall be administered by (A) the Board or (B) a Committee, which committee shall
be constituted to satisfy Applicable Laws.

        (b) 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(l) 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 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;

                                       4
<PAGE>

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

            (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 has declined since the date the Option was granted; and

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

        (b) 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 designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 5(b), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

        (c) Neither the Plan nor any Option or Stock Purchase Right shall confer
upon any Optionee any right with respect to continuation of his or her
employment or consulting 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 or consulting relationship at any time, with or without cause.

        (d) The following limitations shall apply to grants of Options and Stock
Purchase Rights to Employees:

            (i) No Employee shall be granted, in any fiscal year of the Company,
Options and Stock Purchase Rights to purchase more than 75% of the shares
reserved for issuance under the Plan.

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

                                       5
<PAGE>

            (iii) If an Option or Stock Purchase Right is cancelled in the same
fiscal year of the Company in which it was granted (other than in connection
with a transaction described in Section 12), the cancelled Option or Stock
Purchase Right shall be counted against the limit set forth in subsection (i)
above. For this purpose, if the exercise price of an Option or Stock Purchase
Right is reduced, such reduction will be treated as a cancellation of the Option
or Stock Purchase Right and the grant of a new Option or Stock Purchase Right.

     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 stockholders 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. 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 upon
exercise of an Option shall be such price as is determined by the Administrator,
but shall be subject to the following:

            (i) In the case of an Incentive Stock Option

                (A) granted to an Employee who, at the time of grant of such
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.

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

            (ii) In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Administrator. In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                                       6
<PAGE>

        (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). Such consideration may consist 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 such Option shall be exercised, (5) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and
a 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
Administrator 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 Stockholder. Any Option granted
hereunder shall be exercisable at such times and under such conditions as
determined by the Administrator, 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 Administrator, consist of any
consideration and method of payment allowable under Section 8(b) hereof. 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, receive dividends or any other rights
as a stockholder 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 shall 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 hereof.

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

        (b) Termination of Employment or Consulting Relationship. In the event
of termination of an Optionee's Continuous Status as an Employee or Consultant
(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 date three


                                       7
<PAGE>

(3) months and one 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 the Optionee was
entitled to exercise it at the date of such termination. To the extent that the
Optionee was not entitled to exercise the Option at the date of such
termination, or if the 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
Continuous Status as an Employee or Consultant as a result of his or her
disability, the Optionee may, but only within twelve (12) 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. If
such disability is not a "disability" as such term is defined in Section
22(e)(3) of the Code, in the case of an Incentive Stock Option such Incentive
Stock Option shall automatically cease to be treated as an Incentive Stock
Option and shall be treated for tax purposes as a Nonstatutory Stock Option on
the day three months and one day following such termination. To the extent that
the Optionee was not entitled to exercise the Option at the date of termination,
or if the 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 on 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 the Optionee's death, the
Optionee's estate or a person who acquires 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) 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.

     10. Non-Transferability of Options and Stock Purchase Rights. Unless
determined otherwise by the Administrator, 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.

                                       8
<PAGE>

     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 makes 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.

        (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 Stockholder. Once the Stock Purchase Right is exercised,
the purchaser shall have rights equivalent to those of a stockholder and shall
be a stockholder when his or her purchase is entered upon the records of the
duly authorized transfer agent of the Company. No adjustment shall 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
stockholders 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
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


                                       9
<PAGE>

Company. The 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 Administrator 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 shall 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 may be assumed or
an equivalent option or right may be substituted by such successor corporation
or a parent or subsidiary of such successor corporation. If, in such event, an
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 Stock
Purchase Right confers the right to purchase or receive, 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 the holders are offered a
choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares). If such consideration received in the
merger is 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 Administrator. 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 NASD or an established stock exchange), the Company
shall obtain stockholder 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 Administrator, 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, shall
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 Administrator shall approve from time to
time.

     18. Stockholder Approval. Continuance of the Plan shall be subject to
approval by the stockholders of the Company within twelve (12) months before or
after the date the Plan is adopted. Such stockholder 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.
