               (a) The Option shall be fully vested and exercisable three (3)
years after the Date of Grant. Any Optioned Shares that a Non-Employee Director
has the right to purchase but elects not to purchase shall remain available for

and the provisions of the Plan.

               (b) Notwithstanding the provisions of subsection (a) immediately
above, this Option shall be considered fully vested upon the earlier to occur of
(i) termination of the Non-Employee Director's service on the Board by reason of

Director's estate, personal representative or beneficiary, as the case may be)
shall have the right, subject to the other terms and conditions of the Plan, to
exercise all portions of this Option that had vested as of or in connection with
the termination of service at any time within sixty (60) days after the date of
termination of service, subject to earlier expiration of the Option pursuant to

II.     AGREEMENT

               1. GRANT OF OPTION. The Committee hereby grants to the
Non-Employee Director an option (the "Option") to purchase the number of Shares
set forth above at the exercise price per share set forth above (the "Exercise
Price"), subject to the terms and conditions of the Plan, which is incorporated
herein by reference. In the event of a conflict between the terms and conditions
of the Plan and the terms and conditions of this Option Agreement, the terms and
conditions of the Plan shall prevail.

                                       2
<PAGE>   4

               2. EXERCISE OF OPTION.

                  (a) RIGHT TO EXERCISE. This Option is exercisable during its
term in accordance with the Vesting Schedule set forth above and the applicable
provisions of the Plan and this Option Agreement. In the event of Non-Employee
Director's death, disability or other termination of Non-Employee Director, the
applicable provisions of the Plan and this Option Agreement govern the
exercisability of the Option.

                  This Option shall not be exercisable unless the Common Stock
subject hereto has been registered under the Securities Act, and qualified under
applicable state or foreign securities or "blue sky" laws in connection with the
offer and sale thereof, or the Company has determined that an exemption from
registration under the Securities Act and from qualification under such
securities or "blue sky" laws is available. As soon as practicable after the
Effective Date, the Company shall register the issuance of the shares of Common
Stock issuable upon exercise of this Option, and shall, as required by the
Securities Act, maintain from time to time the effectiveness of such
registration.

                  (b) METHOD OF EXERCISE. This Option is exercisable by delivery
of an exercise notice, in the form attached as Exhibit A (the "Exercise
Notice"), which shall state the election to exercise the Option, the number of
Optioned Shares in respect of which the Option is being exercised (the
"Exercised Shares"), and such other representations and agreements as may be
required by the Company pursuant to the provisions of the Plan; provided,
however, that no fewer than 10 shares of Common Stock may be purchased upon any
exercise of this Option unless the number of shares purchased at such time is
the total number of shares in respect of which the Option is then exercisable,
and provided, further, that in no event shall the Option be exercisable for a
fractional share. The Exercise Notice shall be signed by the Non-Employee
Director and shall be delivered in person or by a recognized overnight delivery
service to the Secretary of the Company at 444 Market Street, 15th Floor, San
Francisco, California 94111, or such other address as the Company shall
designate in a written notice to the Non-Employee Director. The Exercise Notice
shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares. The date of exercise of this Option shall be the later of (i)
the date on which the Company receives such written notice, or (ii) the date on
which the conditions provided in Sections 8(d) and 8(e) of the Plan are
satisfied.

                  No Exercised Shares shall be issued pursuant to the exercise
of this Option unless such issuance and exercise complies with all relevant
provisions of law and the requirements of any stock exchange or market upon or
in which the Exercised Shares are then listed and traded. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Non-Employee Director on the date the Option is exercised
with respect to such Exercised Shares.

<PAGE>   5

               3. METHOD OF PAYMENT. Payment of the aggregate Exercise Price
shall be by any of the following, or a combination thereof, at the election of
the Non-Employee Director:

                  (a) Cash or cash equivalent;

                  (b) Previously owned shares;

                  (c) Any combination of the above; or

                  (d) Such other means as the Committee may approve.

               4. NON-TRANSFERABILITY OF OPTION. This Option may not be
transferred, pledged, assigned or otherwise disposed of except by will or the
laws of descent and distribution or pursuant to a domestic relations order,
provided, however, that this Option may be transferred to a member or members of
a Non-Employee Director's immediate family (as defined below) or to one or more
trusts or partnerships or other entity established in whole or in part for the
benefit of one or more of such immediate family members (collectively,
"Permitted Transferees"), subject to the terms of the Plan and such rules and
procedures as may from time to time be adopted or imposed by the Committee.

               If this Option is transferred to a Permitted Transferee, it shall
be further transferable only by will or the laws of descent and distribution or,
for no consideration, to another Permitted Transferee of the Non-Employee
Director. A Non-Employee Director shall notify the Company in writing prior to
any proposed transfer of this Option to a Permitted Transferee and shall furnish
the Company, upon request, with information concerning such Permitted
Transferee's financial condition and investment experience. For purposes of the
Plan and this Option Agreement, a Non-Employee Director's "immediate family"
means any child, stepchild, grandchild, spouse, son-in-law or daughter-in-law
and shall include adoptive relationships; provided, however, that if the Company
adopts a different definition of "immediate family" (or similar term) in
connection with the transferability of employee stock options awarded to
employees of the Company, such definition shall apply, without further action of
the Board, to the Plan or this Option Agreement.

               The terms of the Plan and this Option Agreement shall be binding
upon the executors, administrators, heirs, successors and assigns of the
Non-Employee Director.

               5. TERM OF OPTION. This Option may be exercised only within the
term set forth above, and may be exercised during such term only in accordance
with the Plan and the terms of this Option Agreement.

of the grant and exercise of this Option, and (ii) been advised to consult his
or her tax adviser before exercising this Option or disposing of the Exercised
Shares.

Non-Employee Director's interest except by means of a writing signed by the
Company and Non-Employee Director.

the Company's representative below, the Non-Employee Director and the Company
agree that this Option is granted under and governed by the terms and conditions
of the Plan and this Option Agreement. Non-Employee Director has reviewed the
Plan and this Option Agreement in their entirety, and has had an opportunity to
obtain the advice of counsel prior to executing this Option Agreement.
Non-Employee Director hereby agrees to accept as binding, conclusive and final
all decisions or interpretations of the Committee upon any question relating to
the Plan and this Option Agreement. Non-Employee Director further agrees to
notify the Company upon any change in the residence address indicated below.

               IN WITNESS WHEREOF, the Company and the Non-Employee Director
have executed this Agreement as of the Date of Grant specified above.

Director's estate, personal representative or beneficiary, as the case may be)
shall have the right, subject to the other terms and conditions of the Plan, to
exercise all portions of this Option that had vested as of or in connection with
the termination of service at any time within sixty (60) days after the date of
termination of service, subject to earlier expiration of the Option pursuant to
Section 8(a) of the Plan.

II.     AGREEMENT

               1. GRANT OF OPTION.

                  (a) Pursuant to the Non-Employee Director's election to
convert the stock appreciation rights ("SARs") granted to Non-Employee Director
on October 13, 1999 into an option under Section 7(e) of the Plan and subject to
the terms and conditions of the Plan, which is incorporated herein by reference,
the Committee hereby grants to the Non-Employee Director an option (the
"Option") to purchase the number of Shares

                                       2
<PAGE>   4

set forth above, which equals the number of unexercised SARs held by
Non-Employee Director as of the close of business on the Effective Date, at the
exercise price per share set forth above (the "Exercise Price"), which equals
the grant price of the SARs. The date of grant of this Option set forth above
equals the date of grant of the SARs. In the event of a conflict between the
terms and conditions of the Plan and the terms and conditions of this Option
Agreement, the terms and conditions of the Plan shall prevail.

                  (b) Upon grant of this Option to Non-Employee Director
pursuant to the provisions Section 7(e) of the Plan, the SARs previously held by
Non-Employee Director are cancelled.

               2. EXERCISE OF OPTION.

                  (a) RIGHT TO EXERCISE. This Option is exercisable during its
term in accordance with the Vesting Schedule set forth above and the applicable
provisions of the Plan and this Option Agreement. In the event of Non-Employee
Director's death, disability or other termination of Non-Employee Director, the
applicable provisions of the Plan and this Option Agreement govern the
exercisability of the Option.

                  This Option shall not be exercisable unless the Common Stock
subject hereto has been registered under the Securities Act, and qualified under
applicable state or foreign securities or "blue sky" laws in connection with the
offer and sale thereof, or the Company has determined that an exemption from
registration under the Securities Act and from qualification under such
securities or "blue sky" laws is available. As soon as practicable after the
Effective Date, the Company shall register the issuance of the shares of Common
Stock issuable upon exercise of this Option, and shall, as required by the
Securities Act, maintain from time to time the effectiveness of such
registration.

                  (b) METHOD OF EXERCISE. This Option is exercisable by delivery
of an exercise notice, in the form attached as Exhibit A (the "Exercise
Notice"), which shall state the election to exercise the Option, the number of
Optioned Shares in respect of which the Option is being exercised (the
"Exercised Shares"), and such other representations and agreements as may be
required by the Company pursuant to the provisions of the Plan; provided,
however, that no fewer than 10 shares of Common Stock may be purchased upon any
exercise of this Option unless the number of shares purchased at such time is
the total number of shares in respect of which the Option is then exercisable,
and provided, further, that in no event shall the Option be exercisable for a
fractional share. The Exercise Notice shall be signed by the Non-Employee
Director and shall be delivered in person or by a recognized overnight delivery
service to the Secretary of the Company at 444 Market Street, 15th Floor, San
Francisco, California 94111, or such other address as the Company shall
designate in a written notice to the Non-Employee Director. The Exercise Notice
shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares. The date of exercise of this Option shall be the later of (i)
the date on which the Company receives such written notice, or (ii)

                                       3
<PAGE>   5

the date on which the conditions provided in Sections 8(d) and 8(e) of the Plan
are satisfied.

                  No Exercised Shares shall be issued pursuant to the exercise
of this Option unless such issuance and exercise complies with all relevant
provisions of law and the requirements of any stock exchange or market upon or
in which the Exercised Shares are then listed and traded. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Non-Employee Director on the date the Option is exercised
with respect to such Exercised Shares.

               3. METHOD OF PAYMENT. Payment of the aggregate Exercise Price
shall be by any of the following, or a combination thereof, at the election of
the Non-Employee Director:

                  (a) Cash or cash equivalent;

                  (b) Previously owned shares;

                  (c) Any combination of the above; or

                  (d) Such other means as the Committee may approve.

               4. NON-TRANSFERABILITY OF OPTION. This Option may not be
transferred, pledged, assigned or otherwise disposed of except by will or the
laws of descent and distribution or pursuant to a domestic relations order,
provided, however, that this Option may be transferred to a member or members of
a Non-Employee Director's immediate family (as defined below) or to one or more
trusts or partnerships or other entity established in whole or in part for the
benefit of one or more of such immediate family members (collectively,
"Permitted Transferees"), subject to the terms of the Plan and such rules and
procedures as may from time to time be adopted or imposed by the Committee.

               If this Option is transferred to a Permitted Transferee, it shall
be further transferable only by will or the laws of descent and distribution or,
for no consideration, to another Permitted Transferee of the Non-Employee
Director. A Non-Employee Director shall notify the Company in writing prior to
any proposed transfer of this Option to a Permitted Transferee and shall furnish
the Company, upon request, with information concerning such Permitted
Transferee's financial condition and investment experience. For purposes of the
Plan and this Option Agreement, a Non-Employee Director's "immediate family"
means any child, stepchild, grandchild, spouse, son-in-law or daughter-in-law
and shall include adoptive relationships; provided, however, that if the Company
adopts a different definition of "immediate family" (or similar term) in
connection with the transferability of employee stock options awarded to
employees of the Company, such definition shall apply, without further action of
the Board, to the Plan or this Option Agreement.

                                       4

               The terms of the Plan and this Option Agreement shall be binding
upon the executors, administrators, heirs, successors and assigns of the
Non-Employee Director.

               5. TERM OF OPTION. This Option may be exercised only within the
term set forth above, and may be exercised during such term only in accordance
with the Plan and the terms of this Option Agreement.

               6. TAX CONSEQUENCES. Non-Employee Director hereby acknowledges
that Non-Employee Director has: (i) received and read the Company's Proxy
Statement dated December 5, 2000, including the summary of the tax consequences
of the grant and exercise of this Option, and (ii) been advised to consult his
or her tax adviser before exercising this Option or disposing of the Exercised
Shares.

               7. ENTIRE AGREEMENT.

                  (a) The Plan is incorporated herein by reference. The Plan and
this Option Agreement constitute the entire agreement of the parties with
respect to the subject matter hereof and supersede in their entirety all prior
undertakings and agreements of the Company and the Non-Employee Director with

Non-Employee Director's interest except by means of a writing signed by the
Company and Non-Employee Director.

                  (b) By Non-Employee Director's signature and the signature of
the Company's representative below, the Non-Employee Director and the Company
agree that this Option is granted under and governed by the terms and conditions
of the Plan and this Option Agreement. Non-Employee Director has reviewed the
Plan and this Option Agreement in their entirety, and has had an opportunity to
obtain the advice of counsel prior to executing this Option Agreement.
Non-Employee Director hereby agrees to accept as binding, conclusive and final
all decisions or interpretations of the Committee upon any question relating to
the Plan and this Option Agreement. Non-Employee Director further agrees to
notify the Company upon any change in the residence address indicated below.
