Section 5.2 hereof, the maximum aggregate number of shares of Common Stock which
may be issued and sold hereunder shall be 1,075,000 shares. Shares of Common
Stock issued and sold under the Plan may be either authorized but unissued

designated and approved by the Board. The grant of an Option shall first be
effective upon the date it is approved by the Board, except to the extent the
Board shall specify a later date upon which the grant of an Option shall first
be effective. The Company and the Optionee shall execute an Option Agreement
which shall set forth such terms and conditions of the Option as may be
determined by the Board to be consistent with the Plan, and which may include
additional provisions, conditions and/or restrictions that are not inconsistent
with the Plan.

     6.2 OPTION PRICE. The Option Price shall not be less than one-hundred
percent (100%) of the Fair Market Value of a share of Common Stock on the Date
of Grant.

     6.3 VESTING; TERM OF OPTION. Unless otherwise provided by the Board in an
Option Agreement, Options will vest and become exercisable as to twenty-five
percent (25%) of the Common Stock on the effective date of a Sale of the
Company, and as to an additional twenty-five percent (25%) on each of the first
three anniversaries of such date, provided that the Optionee is employed by the
Company or its successor (or an affiliate thereof) on each such date. Unless
otherwise provided by the Board in an Option Agreement, Options will have a
term of ten (10) years from the Date of Grant, subject to Article VII hereof.
Notwithstanding the foregoing, if a Sale of the Company does not occur within
six months of the Effective Date of the Plan, all Options shall terminate and be
of no further force or effect.

     6.4 OPTION EXERCISE; WITHHOLDING. Subject to such terms and conditions as
shall be specified in an Option Agreement, an Option may be exercised in whole
or in part at any time the Option becomes vested and exercisable, with respect
to whole shares only, within the period permitted for the exercise thereof, and
shall be exercised by written notice of intent to exercise the Option with
respect to a specified number of shares delivered to the Company at its
principal office, and payment in full to the Company at said office of the

respect to which the Option is then being exercised. Payment of the Option Price
shall be made (i) in cash or by cash equivalent acceptable to the Board, (ii) at
the discretion of the Board, in Common Stock that has been held by the Optionee
for at least six months (or such other period as the Board may deem appropriate
for purposes of applicable accounting rules and other considerations), valued at
the Fair Market Value of such shares determined on the date of exercise, (iii)
at the discretion of the Board, by a combination of the methods described above,
or (iv) by such other method as may be approved by the Board. In addition to and
at the time of payment of the Option Price, the Optionee shall pay to the
Company the full amount of all federal and state withholding and other
employment taxes required to be withheld in connection with such exercise, in
any manner consistent with the foregoing that is approved by the Board.

     6.5 CANCELLATION, SUBSTITUTION AND AMENDMENT OF OPTIONS. The Board shall
have the authority to effect, at any time and from time to time, (i) the
cancellation of any or all outstanding Stock Options and the grant in
substitution therefor of new Stock Options covering the same or different
numbers of shares of Common Stock and having an Option Price which

                                       4
<PAGE>

may be the same as or different than the Option Price of the cancelled Options
or (ii) the amendment of the terms of any and all outstanding Stock Options
PROVIDED, HOWEVER, that no such cancellation, substitution or amendment may be
made that adversely affects the terms and conditions of an Option without the
written consent of the Optionee.

     6.6 STATE SECURITIES LAWS. Any Options granted to any Eligible Person by
the Board hereunder and any shares of Common Stock which may be issued and sold
to Eligible Persons hereunder are being offered and sold pursuant to a private
placement exemption under the state securities laws. In order to meet the
conditions and requirements of a private placement exemption under the state
securities laws, each Optionee shall be required to represent in writing to the
Company that the Options received are being acquired for his or her own account,
for investment purposes only, and not with a view to, or for sale in connection
with any, distribution of the security. The Options and shares of Common Stock
are subject to restrictions on transferability and resale and may not be
transferred or resold except as permitted under the Securities Act of 1933, as
amended, and the applicable state securities laws pursuant to registration or an
exemption therefrom.

Option Agreement, if an Optionee shall die at any time after the Date of Grant
and while he or she is an Eligible Person, the executor or administrator of the
estate of the decedent, or the person or persons to whom an Option shall have
been validly transferred in accordance with Section 8.1 hereof pursuant to will
or the laws of descent and distribution, shall have the right, during the period
ending one year after the date of the Optionee's death (subject to the maximum
term of the Option), to exercise an Option to the extent that it was exercisable
at the date of such termination and shall not have been previously exercised.

     7.2 DISABILITY. Unless otherwise provided by the Board and set forth in the
Option Agreement, if an Optionee's employment or other service with the Company
shall be terminated as a result of his or her permanent and total disability
(within the meaning of section 22(e)(3) of the Code) at any time after the Date
of Grant and while he or she is an Eligible Person, the Optionee (or in the case
of an Optionee who is legally incapacitated, his or her guardian or legal
representative) shall have the right, during a period ending one year after the
date of his or her disability (subject to the maximum term of the Option), to
exercise an Option to the extent that it was exercisable at the date of such
termination and shall not have been previously exercised.

     7.3 TERMINATION FOR CAUSE. Unless otherwise provided by the Board and set
forth in the Option Agreement, if an Optionee's employment shall be terminated
for "cause," the Optionee's right to exercise any unexercised portion of an
Option shall immediately terminate and all rights thereunder shall cease. As
used in this Plan, termination for "cause" shall be as defined in the Option
Agreement.

     7.4 OTHER TERMINATION OF SERVICE. Unless otherwise provided by the Board
and set forth in the Option Agreement, if an Optionee's employment shall be

termination for "cause," the Optionee shall have the right, during the period
ending sixty (60) days after such termination (subject to the term of the
Option), to exercise an Option to the extent that it was exercisable at the date
of such termination and shall not have been previously exercised. The Board
shall have authority to determine in each case whether an authorized leave of
absence shall be deemed a termination of employment for purposes hereof, as well
as the effect of a leave of absence on the vesting and exercisability of an
Option.

     7.5 BOARD AUTHORITY. For purposes hereof, the Board shall have the sole
power to make all determinations regarding the termination of any participant's
employment, including, but not limited to, the effective time thereof for the
purposes of this Plan, the cause(s) therefor and the consequences thereof. Any
such determination shall be final, conclusive and binding upon the Optionee.


                                  ARTICLE VIII

                                REPURCHASE RIGHTS

     8.1 NONTRANSFERABILITY. All Options granted under this Plan shall be
nontransferable otherwise than by will or by the laws of descent and
distribution. All shares of Common Stock or other securities acquired by an
Optionee under the Plan shall, prior to the time such securities are Publicly
Traded, be nontransferable except as provided in this Article VIII.

     8.2 PUT OPTION. In the event of a Sale of the Company in which the Options
are assumed or substituted in accordance with Section 5.3 hereof into a stock
option to purchase shares of the Company or a successor corporation (or any
parent or subsidiary thereof) that are not Publicly Traded, all such shares
acquired by an Optionee under the Plan shall, for so long as such securities are
not Publicly Traded, be subject to a "Put Option" of the Optionee as described
in the Option Agreement. The Put Option shall arise upon termination of
employment of the Optionee (other than a termination for "cause") and shall be
limited to all shares acquired by the Optionee that have been issued pursuant to
an Option under the Plan and have been held by the Optionee for a period of six
months. The Put Option shall be exercisable by the Optionee at the time and in
the manner set forth in the Option Agreement and, upon the exercise thereof,
shall require the Optionee to transfer the subject Common Stock to the Company,
its successor or its designee upon payment by the Company or such successor or
designee of a put price per share equal to the Fair Market Value of the Common
Stock at the time of such transfer

                                       6
<PAGE>

Notwithstanding the foregoing, the Put Option shall lapse upon the transfer of
any shares subject to the Put Option by the Optionee to any third party.

     8.3 CALL OPTION. In the event of a Sale of the Company in which the Options
are assumed or substituted in accordance with Section 5.3 hereof into a stock
option to purchase shares of the Company or a successor corporation (or any
parent or subsidiary thereof) that are not Publicly Traded, all such shares of
acquired by an Optionee under the Plan shall, for so long as such securities are
not Publicly Traded, be subject to a "Call Option" of the Company, its successor
or its designee as described in the Option Agreement. The Call Option shall
arise upon the termination of employment or other service of the Optionee with
the Company or its successor and shall relate to all shares of Common Stock
owned by the Optionee at the time of such termination, as well as all shares
acquired by the Optionee following termination, that have been issued pursuant
to an Option under the Plan. The Call Option shall be exercisable by the Company
or its designee at the time and in the manner set forth in the Option Agreement
and, upon the exercise thereof, shall require the Optionee to transfer the
subject Common Stock to the Company, its successor or its designee upon payment
by the Company or such successor or designee of a call price per share equal to
the Fair Market Value of the Common Stock at the time of such transfer. The Call
Option shall survive the transfer of any shares subject to the Call Option by
the Optionee to any third party.

     8.4 RIGHT OF FIRST REFUSAL. In the event of a Sale of the Company in which
the Options are assumed or substituted in accordance with Section 5.3 hereof
into a stock option to purchase shares of the Company or a successor corporation
(or any parent or subsidiary thereof) that are not Publicly Traded, all such
shares acquired by an Optionee under the Plan shall, for so long as such
securities are not Publicly Traded, be subject to a "Right of First Refusal" of
the Company, its successor or its designee as described in the Option Agreement.
If the Optionee proposes to transfer any such shares of Common Stock and the
Company or its successor exercises the Right of First Refusal, the Optionee
shall be obligated to transfer the shares to the Company or its successor at the
price and on the other terms and conditions set forth in the Right of First
Refusal. The Right of First Refusal shall survive the transfer of any shares
subject to the Right by the Optionee to any third party.

                                   ARTICLE IX

                               STOCK CERTIFICATES

     9.1 ISSUANCE OF CERTIFICATES. Subject to Section 9.2 hereof, the Company
shall issue a stock certificate in the name of the Optionee (or other person
exercising the Option in accordance with the provisions of the Plan) for the
shares of Common Stock purchased upon exercise of a Stock Option as soon as
practicable thereafter. The Board may require the Optionee to enter into an
escrow agreement providing that the certificates representing Common Stock
issued pursuant to the Plan will remain in the physical custody of an escrow
holder until all restrictions are removed or expire.

     9.2 CONDITIONS. The Company shall not be required to issue or deliver any
certificate for shares of Common Stock purchased upon the exercise of any Option

hereunder or any portion thereof prior to fulfillment of all of the following
conditions: (i) the completion of any registration or other qualification of
such shares, under any federal or state securities laws or under the rulings or

federal or state governmental agency which the Board shall in its discretion
determine to be necessary or advisable; (iii) the lapse of such reasonable
period of time following the exercise of the Option as the Board from time to
time may establish for reasons of administrative convenience; (iv) satisfaction
by the Optionee of all applicable withholding taxes or other withholding
liabilities; and (v) receipt by the Company from an Optionee of (a) a
representation in writing that the shares of Common Stock received upon exercise
of an Option are being acquired for his or her own account, for investment
purposes only and not with a view to, or for sale in connection with any,
distribution and (b) such other representations and warranties as are deemed
necessary by counsel to the Company.

     9.3 LEGENDS. The Company reserves the right to legend any certificate for
shares of Common Stock, conditioning sales of such shares upon compliance with
applicable federal and state securities laws and regulations. The Board may
require that certificates representing Common Stock issued under the Plan bear a
legend making appropriate reference to the restrictions on transferability and
resale imposed under the Plan and the Option Agreement.

     10.2 AMENDMENT AND TERMINATION. The Board may at any time and from time to
time and in any respect, amend, modify or terminate the Plan; PROVIDED, HOWEVER,

adversely affect any Option theretofore granted without the consent of the
Optionee or the permitted transferee of the Option. Notwithstanding the
foregoing, the Company reserves the right, by action of the Board, to amend the
Plan and the Option Agreements in any manner determined necessary by the Board
to facilitate a Sale of the Company, provided that no such amendment shall
change the exercise price or number of shares subject to an Option, except as
permitted by Article V, nor the vesting and exercisability of an Option, as
provided in Section 6.3. This Plan shall automatically terminate, and all
Options granted hereunder shall be of no further force or effect, if a Sale of
the Company shall not occur within six months of the Effective Date of the Plan.

right to continue in the capacity in which he or she is employed by or otherwise
provides services to the Company or any affiliated company.

     11.2 RIGHTS AS STOCKHOLDER. An Optionee or the permitted transferee of an
Option shall have no rights as a stockholder with respect to any shares subject

not affect any other Stock Option or incentive or other compensation plans in

establishing any other forms of incentive or other compensation for employees of
the Company. The amount of any compensation deemed to be received by an Optionee
as a result of the exercise of an Option or the sale of shares received upon
such exercise shall not constitute compensation with respect to which any other
employee benefits of such Optionee are determined, including, without
limitation, benefits under any bonus, pension, profit sharing, life insurance or
salary continuation plan, except as otherwise specifically determined by the
Board or provided by the terms of such plan.

shall be determined to be illegal or unenforceable by any court of law in any
jurisdiction, the remaining provisions hereof and thereof shall be severable and
enforceable in accordance with their terms, and all provisions shall remain
enforceable in any other jurisdiction.

     11.7 GOVERNING LAW. The validity and construction of this Plan and of the
Option Agreements shall be governed by the laws of the State of California.

violation of any contractual, statutory or common law duty of loyalty to the
Company or any affiliate. The Board shall have the power to determine whether

conclusive and binding upon the Optionee.

requirements of a private placement exemption under the state securities laws,
the Optionee hereby represents to the Company that the Options received are
being acquired for his or her own account, for investment purposes only, and not
with a view to, or for sale in connection with any, distribution of the
security. The Options and Option Shares are subject to restrictions on

registration statement under the Securities Act relating to the Option Shares,
the Optionee hereby represents and warrants, and by virtue of such exercise
shall be deemed to represent and warrant, to the Company that the Option Shares
shall be acquired for the Optionee's own account for investment purposes only,
and not with a view to, or for sale in connection with, the distribution
thereof, and the Optionee shall provide the Company with such further
representations and warranties as the Company may require in order to ensure

laws.

unless and until the Company and or the Optionee shall have complied with all
applicable federal or state registration, listing and/or qualification
requirements and all other requirements of law or of any regulatory agencies
having jurisdiction, unless the Board has received evidence satisfactory to it
that a prospective Optionee may acquire such shares pursuant to an exemption
from registration under the applicable securities laws, Any determination in
this connection by the Board shall be final, binding, and conclusive. The
Company reserves the right to legend any certificate for shares of Common Stock,
conditioning sales of such shares upon compliance with applicable federal and
state securities laws and regulations.

     SECTION 9. NO RIGHTS AS STOCKHOLDER OR EMPLOYEE.

Stock are entitled with respect to any such Option Shares, until the date of the
issuance to the Optionee of a stock certificate evidencing such shares.

     (b) Nothing in this Agreement or the Option shall confer upon the Optionee
any right to continue in employment with the Company or to interfere in any way
with the right of the Company to terminate the employment of the Optionee at any
time.

     SECTION 10. ADJUSTMENTS. If at any time while the Option is outstanding,
the number of outstanding shares of Common Stock is changed by reason of a

and/or the Option Price of such Option Shares shall be adjusted in accordance
with the provisions of the Plan.

     SECTION 11. CONVERSIONS. In the event of a Sale of the Company, the Option

accordance with Section 5.3 of the Plan. Upon the occurrence of any such
assumption or substitution, the Option shall continue in the manner and under
the terms so provided.

transferred, pledged, assigned, hypothecated or otherwise disposed of in any way
by the Optionee, except by will or by the laws of descent and distribution. In
the event an Optionee becomes legally incapacitated, his Option shall be
exercisable by his legal guardian, committee, or legal representative. If the
Optionee dies, the Option shall thereafter be exercisable by the Optionee's
executors or administrators. The Option shall not be subject to execution,

Market Value (as determined pursuant to the Plan) of the shares on the date of
such termination of employment. To exercise the Put Option, the Optionee shall
notify the Company in writing of the Optionee's decision to exercise the Put

successor at a price per share equal to the Fair Market Value (as determined
pursuant to the Plan) at the time of transfer. The Right of First Refusal shall
survive the transfer of any shares subject to the Right by the Optionee to any
third Party.

the certificates representing the Option Shares shall bear a legend (which
legend shall be removed upon assumption or substitution of the Option in
