with the Participating Company Group, whether in the capacity of an Employee, a
Director or a Consultant. The Optionee's Service shall not be deemed to have
terminated merely because of a change in the capacity in which the Optionee
renders Service to the Participating Company Group or a change in the
Participating Company for which the Optionee renders such Service, provided that
there is no interruption or termination of the Optionee's Service. Furthermore,
only to such extent as may be provided by the Company's leave policy, the
Optionee's Service with the Participating Company Group shall not be deemed to

provided by the Company's leave policy. The Optionee's Service shall be deemed

discretion, shall determine whether the Optionee's Service has terminated and

this Section, an Optionee's Service shall not be deemed to have terminated
merely because the Participating Company for which the Optionee renders Service
ceases to be a member of the Participating Company Group by reason of a Spinoff
Transaction, nor shall Service be deemed to have terminated upon resumption of
Service from the Spinoff Company to a Participating Company. For all purposes
under this Agreement, the Optionee's Service shall include Service, whether in
the capacity of an Employee, Director or a Consultant, for the Spinoff Company
provided the Optionee was employed by the Participating Company Group
immediately prior to the Spinoff Transaction. Notwithstanding the foregoing, if
the Company's auditors determine that the provisions or operation of the
preceding two sentences would cause the Company to incur a compensation expense
and provided further that in the absence of the preceding two sentences no such
compensation expense would be incurred, then the two preceding sentences shall
be without force or effect, and the vesting and exercisability of each
outstanding Option and any shares acquired upon the exercise thereof shall be
determined under any other applicable provision of this Agreement.

adjusted from time to time in accordance with Section 4.2.

present or future "subsidiary corporation" of the Company, as defined in Section
424(f) of the Code.

with which the Company is merged or consolidated or which acquires all or
substantially all of the assets of the Company and which is designated by the
Board as a Successor for purposes of this Agreement.

         1.2 CONSTRUCTION. Captions and titles contained herein are for
convenience only and shall not affect the meaning or interpretation of any
provision of this Agreement. Except when otherwise indicated by the context, the

will vest as provided in the Grant Notice.

         3. EXERCISE OF THE OPTION.

                  3.1 METHOD OF EXERCISE. You may exercise the vested portion of
this Option at any time prior to the expiration of the Option by delivering a
notice of exercise in such form as may be designated by the Company from time to
time together with the exercise price to the Secretary of the Company, or to
such other person as the Company may designate, during regular business hours
and prior to the expiration of the Option, together with such additional
documents as the Company may then require.

                  3.2 METHOD OF PAYMENT. Payment of the exercise price may be by
cash (or check), or pursuant to a program developed under Regulation T as
promulgated by the Federal Reserve Board which, prior to the issuance of Stock,
results in either the receipt of cash (or check) by the Company or the receipt
of irrevocable instructions to a broker which provides for the payment of the
aggregate exercise price to the Company, or a combination of the above methods,
as the Company may designate from time to time. The Company reserves, at any and
all times, the right, in the Company's sole and absolute discretion, to
establish, decline to approve or terminate any program or procedures for the
exercise of Options by means of a Cashless Exercise.

                  3.3 TAX WITHHOLDING. By exercising this Option you agree that
as a condition to any exercise of this Option, the Company may withhold from
your pay and any other amounts payable to you, or require you to enter an
arrangement providing for the payment by you to the Company of any tax
withholding obligation of the Company arising by reason of (1) the exercise of
this Option; or (2) the disposition of Stock acquired upon such exercise.

                  3.4 RESPONSIBILITY FOR EXERCISE. You are responsible for
taking any and all actions as may be required to exercise this Option in a
timely manner and for properly executing any such documents as may be required
for exercise in accordance with such rules and procedures as may be established
from time to time. By signing this Agreement you acknowledge that information
regarding the procedures and requirements for this exercise of the Option is
available to you on request. The Company shall have no duty or obligation to
notify you of the expiration date of this Option.

         4. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, this Option may not be exercised unless the Stock issuable
upon exercise of this Option is then registered under the Securities Act or, if
such Stock is not then so registered, the Company has determined that such
exercise and issuance would be exempt from the registration requirements of the
Securities Act.

         5. TERMINATION OF THE OPTION. The term of this Option commences on the
Date of Grant (as specified in the Grant Notice) and expires and shall no longer
be exercisable upon the earliest of:


                                      -5-


                  5.1 the Expiration Date indicated in the Grant Notice;

                  5.2 the last day for exercising the Option following
termination of your Service as described in Section 6 below; or

                  5.3 a Change of Control, to the extent provided in Section 7
below.

         6. EFFECT OF TERMINATION OF SERVICE.

                  6.1 OPTION EXERCISABILITY. Subject to earlier termination of
the Option as otherwise provided herein, the Option shall be exercisable after
the Optionee's termination of Service only during the applicable time period
determined in accordance with this Section 6 and thereafter shall terminate.

                           (a) DISABILITY. If the Optionee's Service terminates
because of the Disability of the Optionee, the Option shall continue for the
period of such Disability and may be exercised by the Optionee at any time
during the period of Disability but in any event no later than the Expiration
Date.

                           (b) DEATH. If the Optionee's Service terminates
because of the death or because of the Disability of the Optionee and such
termination is subsequently followed by the death of the Optionee, (A) the
exercisability and vesting of the Option shall be accelerated effective upon the
Optionee's death, and (B) the Option, to the extent unexercised and exercisable
on the date of the Optionee's death, may be exercised by the Optionee's legal
representative or other person who acquired the right to exercise the Option by
reason of the Optionee's death at any time prior to the expiration of twelve
(12) months after the date of the Optionee's death, but in any event no later
than the Expiration Date.

                           (c) TERMINATION UPON TRANSFER TO NON-CONTROL
AFFILIATE. If at the request of the Company, the Optionee transfers Service to a
Non-Control Affiliate and the Optionee's Service ceases as a result, then,
subject to the Optionee's execution of a general release of claims form
reasonably satisfactory to the Company, the Option, to the extent unexercised
and exercisable on the date on which the Optionee's Service terminated, may be
exercised by the Optionee (or the Optionee's guardian or legal representative)
at any time prior to the expiration of twelve (12) months after the date on
which the Optionee's Service terminated, but in any event no later than the
Expiration Date.

                           (d) TERMINATION AFTER CHANGE IN CONTROL. If the
Optionee's Service ceases as a result of Termination After Change in Control (as
defined below), then (A) the exercisability and vesting of the Option shall be
accelerated effective as of the date on which the Optionee's Service terminated,
and (B) the Option, to the extent unexercised and exercisable on the date on
which the Optionee's Service terminated, may be exercised by the Optionee (or
the Optionee's guardian or legal representative) at any time prior to the
expiration of six (6) months after the date on which the Optionee's Service
terminated, but in any event no later than the Expiration Date.

                           (e) OTHER TERMINATION OF SERVICE. If the Optionee's
Service with the Participating Company Group terminates for any reason except
Disability, death, Transfer to a Non-Control Affiliate, or Termination after
Change in Control, the Option, to the extent unexercised and exercisable by the


                                      -6-


Optionee on the date on which the Optionee's Service terminates, may be
exercised by the Optionee at any time prior to the expiration of thirty (30)
days after the date on which the Optionee's Service terminates, but in any event
no later than the Expiration Date.

                  6.2 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding
the foregoing, other than termination for Cause, if the exercise of an Option
within the applicable time periods set forth in Section 6.1 is prevented by the
provisions of Section 4 above, the Option shall remain exercisable until three
(3) months after the date the Optionee is notified by the Company that the
Option is exercisable, but in any event no later than the Expiration Date.

                  6.3 EXTENSION IF OPTIONEE SUBJECT TO SECTION 16(B).
Notwithstanding the foregoing, other than termination for Cause, if a sale
within the applicable time periods set forth in Section 6.1 of shares acquired
upon the exercise of the Option would subject the Optionee to suit under Section
16(b) of the Exchange Act, the Option shall remain exercisable until the
earliest to occur of (i) the tenth (10th) day following the date on which a sale
of such shares by the Optionee would no longer be subject to such suit, (ii) the
one hundred and ninetieth (190th) day after the Optionee's termination of
Service, or (iii) the Expiration Date.

                  6.4 CERTAIN DEFINITIONS.

                           (a) "CAUSE" shall mean any of the following: (1) the
Optionee's theft, dishonesty, or falsification of any Participating Company
documents or records; (2) the Optionee's improper use or disclosure of a
Participating Company's confidential or proprietary information; (3) any action
by the Optionee which has a detrimental effect on a Participating Company's
reputation or business; (4) the Optionee's failure or inability to perform any
reasonable assigned duties after written notice from a Participating Company of,

material breach by the Optionee of any employment or service agreement between
the Optionee and a Participating Company, which breach is not cured pursuant to
the terms of such agreement; (6) the Optionee's conviction (including any plea
of guilty or nolo contendere) of any criminal act which impairs the Optionee's

a material Company policy.

                           (b) "GOOD REASON" shall mean any one or more of the
following:

                                    (i) without the Optionee's express written

Company Group to pay, or any material reduction by the Participating Company
Group of, (A) the Optionee's base salary in effect immediately prior to the date
of the Change in Control (unless reductions comparable in amount and duration
are concurrently made for all other employees of the Participating Company Group
with responsibilities, organizational level and title comparable to the
Optionee's), or (B) the Optionee's bonus compensation, if any, in effect
immediately prior to the date of the Change in Control (subject to applicable
performance requirements with respect to the actual amount of bonus compensation
earned by the Optionee);

                                    (iv) any failure by the Participating
Company Group to (A) continue to provide the Optionee with the opportunity to
participate, on terms no less favorable than those in effect for the benefit of
any employee or service provider group which customarily includes a person
holding the employment or service provider position or a comparable position
with the Participating Company Group then held by the Optionee, in any benefit
or compensation plans and programs, including, but not limited to, the
Participating Company Group's life, disability, health, dental, medical,
savings, profit sharing, stock purchase and retirement plans, if any, in which
the Optionee was participating immediately prior to the date of the Change in
Control, or their equivalent, or (B) provide the Optionee with all other fringe
benefits (or their equivalent) from time to time in effect for the benefit of
any employee group which customarily includes a person holding the employment or
service provider position or a comparable position with the Participating
Company Group then held by the Optionee;

                                    (v) any breach by the Participating Company
Group of any material agreement between the Optionee and a Participating Company
concerning Optionee's employment; or

                                    (vi) any failure by the Company to obtain
the assumption of any material agreement between the Optionee and the Company
concerning the Optionee's employment by a successor or assign of the Company.

                           (c) "TERMINATION AFTER CHANGE IN CONTROL" shall mean
either of the following events occurring within twenty-four (24) months after a
Change in Control:

                                    (i) termination by the Participating Company
Group of the Optionee's Service with the Participating Company Group for any
reason other than for Cause; or

                                    (ii) the Optionee's resignation for Good
Reason from all capacities in which the Optionee is then rendering Service to
the Participating Company Group within a reasonable period of time following the
event constituting Good Reason.

Notwithstanding any provision herein to the contrary, Termination After Change
in Control shall not include any termination of the Optionee's Service with the
Participating Company Group which (1) is for Cause; (2) is a result of the
Optionee's death or Disability; (3) is a result of the Optionee's voluntary
termination of Service other than for Good Reason; or (4) occurs prior to the
effectiveness of a Change in Control.


                                      -8-


         7. CHANGE IN CONTROL. In the event of a Change in Control, the
surviving, continuing, successor, or purchasing corporation or other business
entity or parent thereof, as the case may be (the "ACQUIRING Corporation"), may,
without the consent of the Optionee, either assume the Company's rights and
obligations the Option or substitute for the Option substantially equivalent
options for the Acquiring Corporation's stock. In the event the Acquiring
Corporation elects not to assume or substitute for the Option in connection with
a Change in Control, the exercisability and vesting of the Option shall be
accelerated, effective as of the date ten (10) days prior to the date of the
Change in Control. The exercise or vesting of this Option that was permissible
solely by reason of this Section shall be conditioned upon the consummation of
the Change in Control. To the extent this Option is neither assumed or
substituted for by the Acquiring Corporation in connection with the Change in
Control nor exercised as of the date of the Change in Control, it shall
terminate and cease to be outstanding effective as of the date of the Change in
Control. Notwithstanding the foregoing, shares acquired upon exercise of the
Option prior to the Change in Control and any consideration received pursuant to
the Change in Control with respect to such shares shall continue to be subject
to all applicable provisions of the Agreement. Furthermore, notwithstanding the
foregoing, if the corporation the stock of which is subject to the Option
immediately prior to an Ownership Change Event described in Section 1.1(q)(i)
constituting a Change in Control is the surviving or continuing corporation and
immediately after such Ownership Change Event less than fifty percent (50%) of
the total combined voting power of its voting stock is held by another
corporation or by other corporations that are members of an affiliated group
within the meaning of Section 1504(a) of the Code without regard to the
provisions of Section 1504(b) of the Code, the Option shall not terminate unless
the Board otherwise provides in its discretion.

         8. OPTION NOT A SERVICE CONTRACT. This Option is not an employment or
service contract and nothing in this Agreement or the Grant Notice shall be
deemed to create in any way whatsoever any obligation on your part to continue
in the service of the Company, or of the Company to continue your service with
the Company. In addition, nothing in your Option shall obligate the Company, its
stockholders, Board, Officers or Employees to continue any relationship which
you might have as a Director or Consultant for the Company.

         9. ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of any
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification or similar change in the capital structure of the Company,
appropriate adjustments shall be made in the number and class of shares subject
to the Option and in the exercise price per share of the Option. If a majority
of the shares of Stock are exchanged for, converted into, or otherwise become
(whether or not pursuant to an Ownership Change Event) shares of another
corporation (the "NEW SHARES"), the Board may unilaterally amend this Agreement
to provide that the Option is exercisable for New Shares. In the event of any
such amendment, the number of shares subject to, and the exercise price per
share of, the Option shall be adjusted in a fair and equitable manner as
determined by the Board, in its discretion. Notwithstanding the foregoing, any
fractional share resulting from an adjustment pursuant to this Section shall be
rounded down to the nearest whole number, and in no event may the exercise price
of the Option be decreased to an amount less than the par value, if any, of the
Stock subject to the Option.

         10. REPRESENTATIONS. By executing this Agreement, you hereby warrant
and represent that you are acquiring this Option for your own account and that
you have no intention of distributing, transferring or selling all or any part
of this Option except in accordance with the terms of this Agreement and Section
25102(f) of the California Corporations Code. You also hereby warrant and
represent that you have either (i) preexisting personal or business
relationships with the Company or any of its officers, directors or controlling
persons, or (ii) the capacity to protect your own interests in connection with
the grant of this Option by virtue of the business or financial expertise of you
or any of your professional advisors who are unaffiliated with and who are not
compensated by the Company or any of its affiliates, directly or indirectly.

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

         12. TRANSFERABILITY. This Option shall not be transferable in any
manner (including without limitation, sale, alienation, anticipation, pledge,
encumbrance, or assignment) other than, (i) by will or by the laws of descent
and distribution, (ii) by written designation of a beneficiary, in a form
acceptable to the Company, with such designation taking effect upon the death of
the Optionee, (iii) by delivering written notice to the Company, in a form
acceptable to the Company (including such representations, warranties and
indemnifications as the Company shall require the Optionee to make to protect
the Company's interests and ensure that this Option has been transferred under
the circumstances approved by the Company), by gift to the Optionee's spouse,
former spouse, children, stepchildren, grandchildren, parent, stepparent,
grandparent, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law,
daughter-in-law, brother-in-law, or sister-in-law, persons having one of the
foregoing types of relationship with the Optionee due to adoption, any person
sharing the Optionee's household (other than a tenant or employee), a foundation
in which these persons or the Optionee control the management of assets, and any
other entity in which these persons (or the Optionee) own more than fifty
percent of the voting interests. A transfer to an entity in which more than
fifty percent of the voting interests are owned by these persons (or the
Optionee) in exchange for an interest in that entity is specifically included as
a permissible type of transfer. In addition, a transfer to a trust created
solely for the benefit (i.e., the Optionee and/or any or all of the foregoing
persons hold more than 50 percent of the beneficial interest in the trust) of
the Optionee and/or any or all of the foregoing persons is also a permissible
transferee, or (iv) such other transferees as may be authorized by the Board in
its sole and absolute discretion. During the Optionee's life this Option is
exercisable only by the Optionee or a transferee satisfying the above
conditions. Except in the event of the Optionee's death, upon transfer of this
Option to any or all of the foregoing persons, the Optionee is liable for any
and all taxes due upon exercise of this transferred Option. At no time will a
transferee who is considered an affiliate under Rule 144(a)(1) be able to sell
any or all such Stock without complying with Rule 144. The right of a transferee
to exercise the transferred portion of this Option shall terminate in accordance
with the Optionee's right of exercise under this Option and is further subject
to such representations, warranties and indemnifications from the transferee
that the Company requires the transferee to make to protect the Company's
interests and ensure that this Option has been transferred under the
circumstances approved by the Company. Once a portion of this Option is
transferred, no further transfer may be made of that portion of this Option.


                                      -10-


         13. ARBITRATION. Any dispute or claim concerning the Option, the Grant
Notice or this Agreement shall be fully, finally and exclusively resolved by
binding arbitration conducted by the American Arbitration Association pursuant
to the commercial arbitration rules in San Diego, California. By accepting the
Option, the Optionee and the Company waive their respective rights to have any
such disputes or claims tried by a judge or jury.

         14. AMENDMENT. The Board may amend your Option at any time, provided no
such amendment may adversely affect the Option or any unexercised portion of
your Option, without your consent unless such amendment is necessary to comply
with any applicable law or government regulation. No amendment or addition to
this Agreement shall be effective unless in writing or, in such electronic form
as may be designated by the Company.
