     1.   Purposes of the Plan.  The purposes of this Stock Plan are:

               Consultants, 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

          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

their original purchase price, such Shares shall become available 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.  The Plan may be
administered by different Committees with respect to different groups of Service
Providers.

               (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, subject to the specific duties delegated
by the Board to such Committee, 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(n) of the Plan;

               (ii) to select the Employees, Directors and Consultants to whom
Options and Stock Purchase Rights may 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 Option and Stock Purchase Right granted hereunder;

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

               (vi) to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any award granted hereunder.  Such terms and
conditions include, but are not limited to, the exercise price, the time or
times when Options or Stock Purchase Rights may be exercised (which may be based
on performance criteria), any vesting acceleration or waiver of forfeiture
restrictions, and any restriction or limitation regarding any Option or Stock
Purchase Right or the shares of Common Stock relating thereto, based in each
case on such factors as the Administrator, in its sole discretion, shall
determine;

               (vii) to reduce the exercise price of any Option or Stock
Purchase Right to the then current Fair Market Value if the Fair Market Value of
the Common Stock covered by such Option or Stock Purchase Right shall have
declined since the date the Option or Stock Purchase Right was granted;

               (viii) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan;

               (ix) to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;




               (x) to modify or amend each Option or Stock Purchase Right
(subject to Section 15(c) of the Plan), including the discretionary authority to
extend the post-termination exercisability period of Options longer than is
otherwise provided for in the Plan;

               (xi) to authorize any person to execute on behalf of the Company
any instrument required to effect the grant of an Option or Stock Purchase Right
previously granted by the Administrator;

               (xii) to institute an Option Exchange Program;

               (xiii) to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option or Stock Purchase Right that number of Shares
having a Fair Market Value equal to the amount required to be withheld.  The
Fair Market Value of the Shares to be withheld shall be determined on the date
that the amount of tax to be withheld is to be determined.  All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable;

               (xiv) to make all other determinations deemed necessary or
advisable for administering the Plan.

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

     5.   Eligibility.  Nonstatutory Stock Options and Stock Purchase Rights may
be granted to Employees, Directors and Consultants.  Incentive Stock Options may
be granted only to Employees.  

     6.   Limitations.

          (a)  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 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted.  The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

          (b)  Neither the Plan nor any Option or Stock Purchase Right shall
confer upon an Optionee any right with respect to continuing the Optionee's
employment relationship, directorship or consulting relationship with the
Company, nor shall they interfere in any way with the Optionee's right or the
Company's right to terminate such employment relationship, directorship or
consulting relationship at any time, with or without cause.




          (c)  The following limitations shall apply to grants of Options and
Stock Purchase Rights to Employees, Directors and Consultants:

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

               (ii) In connection with his or her initial service with the
Company, an Employee, Director or Consultant may be granted Options and Stock
Purchase Rights to purchase up to an additional 200,000 Shares which shall not
count against the limit set forth in subsection (i) above.

               (iii) The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 13. 

               (iv) 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 13), the cancelled Option or
Stock Purchase Right will be counted against the limits set forth in subsections
(i) and (ii) above.  For this purpose, if the exercise price of an Option or
Stock Purchase Right is reduced, the transaction will be treated as a
cancellation of the Option or Stock Purchase Right and the grant of a new Option
or Stock Purchase Right.

     7.   Term of Plan.  Subject to Section 19 of the Plan, the Plan shall
become effective upon the earlier to occur of its adoption by the Board or its
approval by the shareholders of the Company as described in Section 19 of the
Plan.  It shall continue in effect for a term of ten (10) years unless
terminated earlier under Section 15 of the Plan.

     8.   Term of Option.  The term of each Option shall be stated in the Notice
of Grant; provided, however, that in the case of an Incentive Stock Option, the
term shall be ten (10) years from the date of grant or such shorter term as may
be provided in the Notice of Grant.  Moreover, in the case of an Incentive Stock
Option granted to an Optionee who, at the time the Incentive Stock 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 Incentive Stock Option shall be five (5) years from the date of grant or
such shorter term as may be provided in the Notice of Grant.

     9.   Option Exercise Price and Consideration.

          (a)  Exercise Price.  The per share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

               (i)  In the case of an Incentive Stock Option

                    (A)  granted to an Employee who, at the time the Incentive
Stock 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 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 Employee other than an Employee
described in paragraph (A) immediately above, 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.

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

          (b)  Waiting Period and Exercise Dates.  At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.  In so doing, the Administrator may specify that an
Option may not be exercised until the completion of a service period.

          (c)  Form of Consideration.  The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment.  In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant.  Such
consideration may consist entirely of:

                (i) cash;

               (ii) check;

              (iii) promissory note;

               (iv) other Shares which (A) 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 (B) 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;

               (v) 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;




               (vi) a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

              (vii) any combination of the foregoing methods of payment; or

             (viii) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.

     10.  Exercise of Option.

          (a)  Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement.

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

               An Option shall be deemed exercised when the Company receives:
(i) written notice of exercise (in accordance with the Option Agreement) from
the person entitled to exercise the Option, and (ii) full payment for the Shares
with respect to which the Option is exercised.  Full payment may consist of any
consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan.  Shares issued upon exercise of
an Option shall be issued in the name of the Optionee or, if requested by the
Optionee, in the name of the Optionee and his or her spouse.  Until the stock
certificate evidencing such Shares is issued (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the
Company), no right to vote or receive dividends or any other rights as a
shareholder shall exist with respect to the Optioned Stock, notwithstanding the
exercise of the Option.  The Company shall issue (or cause to be issued) such
stock certificate promptly after the Option is exercised.  No adjustment will be
made for a dividend or other right for which the record date is prior to the
date the stock certificate is issued, except as provided in Section 13 of the
Plan.

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

          (b)  Termination of Employment, Consulting Relationship or
Directorship.  Upon termination of an Optionee's Continuous Status as an
Employee, Director or Consultant, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option, but only within such
period of time as is specified in the Notice of Grant, and only to the extent
that the Optionee was entitled to exercise it at the date of termination (but in
no event later than the expiration of the term of such Option as set forth in
the Notice of Grant).  In the absence of a specified time in the Notice of
Grant, the Option shall remain exercisable for three (3) months following the
Optionee's termination.  In the case of an Incentive Stock Option, such period
of time for exercise shall not exceed three (3) months from the date of
termination.  If, on the date of termination, the Optionee is 




not entitled to exercise the Optionee's 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 or her Option within the time
specified by the Administrator, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

          Notwithstanding the above, in the event of an Optionee's change in
status from Consultant or Director to Employee or Employee or Director to
Consultant, an Optionee's Continuous Status as a Director or Consultant shall
not automatically terminate solely as a result of such change in status. 
However, in such event, an Incentive Stock Option held by the Optionee shall
cease to be treated as an Incentive Stock Option and shall be treated for tax
purposes as a Nonstatutory Stock Option three months and one day following such
change of status from an Employee to a Consultant.  

          (c)  Disability of Optionee.  In the event that 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 at any
time within twelve (12) months from the date of such termination, but only to
the extent that the Optionee was entitled to exercise it at the date of such
termination (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant).  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 or her Option 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)  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.

     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, by means of a Notice of Grant, of the terms, conditions and 




restrictions related to the offer, including the number of Shares that the
offeree shall be entitled to purchase, the price to be paid, and the time within
which the offeree must accept such offer, which shall in no event exceed six (6)
months 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.

          (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 a rate determined by the
Administrator.

          (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 13
of the Plan.

     12.  Non-Transferability of Options and Stock Purchase Rights.  Unless
determined otherwise by the Administrator, an Option or Stock Purchase Right 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.  If the
Administrator makes an Option or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.

     13.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or
          Asset Sale. 

          (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 and 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 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 Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction.  The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable.  In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated.  To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

          (c)  Merger or Asset Sale.  In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Stock Purchase Right shall be
assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation.  In the
event that the successor corporation refuses to assume or substitute for the
Option or Stock Purchase Right, the Optionee shall have the right to exercise
the Option or Stock Purchase Right as to all of the Optioned Stock, including
Shares as to which it would not otherwise be exercisable.  If an Option or Stock
Purchase Right is exercisable in lieu of assumption or substitution in the event
of a merger or sale of assets, the Administrator shall notify the Optionee that
the Option or Stock Purchase Right shall be fully exercisable for a period of
fifteen (15) days from the date of such notice, and the Option or Stock Purchase
Right shall terminate upon the expiration of such period.  For the purposes of
this paragraph, the Option or Stock Purchase Right shall be considered assumed
if, following the merger or sale of assets, the option or 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 or sale of
assets, the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets 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 or sale of assets 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 or sale of assets.




     14.  Date of Grant.  The date of grant of an Option or Stock Purchase Right
shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator.  Notice of the determination shall
be provided to each Optionee within a reasonable time after the date of such
grant.

     15.  Amendment and Termination of the Plan.

          (a)  Amendment and Termination.  The Board may at any time amend,
alter, suspend or terminate the Plan.  

          (b)  Shareholder Approval.  The Company shall obtain shareholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Sections 162(m) or 422 of the Code (or any successor rule or statute or
other applicable law, rule or regulation, including the requirements of any
exchange or quotation system on which the Common Stock is listed or quoted). 
Such shareholder approval, if required, shall be obtained in such a manner and
to such a degree as is required by the applicable law, rule or regulation.

          (c)  Effect of Amendment or Termination.  No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.

     16.  Conditions Upon Issuance of Shares.  

          (a)  Legal Compliance.  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 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, Applicable Laws, and the requirements of any stock
exchange or quotation system upon which the Shares may then be listed or quoted,
and shall be further subject to the approval of counsel for the Company with
respect to such compliance.

          (b)  Investment Representations.  As a condition to the exercise of an
Option 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.

     17.  Liability of Company.

          (a)  Inability to Obtain Authority.  The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of 




any liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

          (b)  Grants Exceeding Allotted Shares.  If the Optioned Stock covered
by an Option or Stock Purchase Right exceeds, as of the date of grant, the
number of Shares which may be issued under the Plan without additional
shareholder approval, such Option or Stock Purchase Right shall be void with
respect to such excess Optioned Stock, unless shareholder approval of an
amendment sufficiently increasing the number of Shares subject to the Plan is
timely obtained in accordance with Section 15(b) of the Plan.

     18.  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.

     19.  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 manner and to the degree required under applicable federal and state law.
