                 7.       Issuance of Shares.

                          (a)     On the last trading of each Semi-Annul Period
during the term of the Plan, and provided the Participant has not before that
date advised the Corporation that he or she does not wish Shares purchased for
his or her account on that date, the Corporation shall apply the funds in the
Participant's account as of that date to the purchase of Shares of its Common
Stock in units of one (1) full Share or multiples thereof.  No fractional
shares shall be purchased or issued.

                          (b)     The per share cost to each Participant for
the Shares so purchased shall be eighty-five percent (85%) of the lower of (i)
the Fair Market Value of a share of the Common Stock on the first trading day
of the Semi-Annual Period (the "date of grant") or (ii) the Fair Market Value
of a share of the Common Stock on the last trading day of the Semi-Annual
Period (the "date of exercise").

                          (c)     Any moneys remaining in such Participant's
account equaling less than the sum required to purchase one full Share, or
moneys remaining in such Participant's account by reason of application of the
provisions of Section 7(d) hereof, shall, unless otherwise requested by the
Participant, be held in the Participant's account for use during the next
Semi-Annual Period.  Any moneys remaining in such Participant's account by
reason of his or her prior election not to purchase Shares in a given
Semi-Annual Period shall be disbursed to the Participant within thirty (30)
days of the end of such Semi-Annual Period.  The Corporation shall as
expeditiously as possible after the last day of each Semi-Annual Period issue
to the Participant entitled thereto the certificate evidencing the Shares
issuable to him or her as provided herein.

                          (d)     Notwithstanding anything above to the
contrary, (i) if the aggregate number of Shares that all Participants in the
Plan desire to purchase at the end of any Semi-Annual Period exceeds the number
of Shares then available under the Plan, the Shares available shall be
allocated among such Participants in proportion to their contributions during
the Semi-Annual Period (but no fractional Shares shall be purchased or issued)
and (ii) no funds in a Participant's account shall be applied to the purchase
of Shares and no Shares shall be issued hereunder, unless the issuance and sale
of such Shares are covered by an effective registration statement under the
Securities Act of 1933, as amended, or is exempt from such registration
requirements.

                 8.       Termination of Participation.  A Participant's
participation in the Plan will be terminated when the Participant (a)
voluntarily elects to withdraw his or her entire account, (b) resigns or is
discharged, with or without cause, from the Corporation or one of its present
or future Parent or Subsidiary corporations, (c) dies, or (d) does not receive
salary or other compensation from the Corporation or one of its present or
future Parent or Subsidiary corporations for twelve (12) consecutive months,
unless this period is due to illness, injury or for

other reasons approved by the Committee.  Upon termination of participation,
the terminated Participant shall not be entitled to rejoin the Plan until the
first day of the Semi-Annual Period immediately following the Semi-Annual
Period in which the termination occurs.  Except in the case of a voluntary
termination under Sections 7(c) and 8(a) hereof, if a termination of
participation occurs prior to the last trading of a Semi-Annual Period, (i)
Shares will be issued for the Semi-Annual Period in which the termination
occurred in accordance with the Plan based upon the balance in such
Participant's account on the date of termination of participation, (ii) no
further payroll deductions or contributions shall be permitted, and (iii) the
Participant shall be entitled to payment of the balance of the amount of his or
her individual account within thirty (30) days after the end of such
Semi-Annual Period.

                 9.       Beneficiary.

                          (a)     Each Participant may file a written
designation of a beneficiary who is to receive any Shares credited to such
Participant's account under the Plan in the event of the death of such
Participant prior to the last trading day of a Semi-Annual Period and/or prior
to delivery to such Participant of the certificates for such Shares.  Such
designation may be changed by the Participant at any time by written notice
received by the Corporation.

                          (b)     Upon the death of a Participant, promptly
following the end of the Semi-Annual Period during which the death occurred,
all Shares and amounts remaining in his or her account after the final purchase
of Shares in accordance with Section 7 hereof shall be paid or distributed to
the beneficiary or beneficiaries designated by such Participant, or in the
absence of such designation, to the executor or administrator of his or her
estate, and in either event the Corporation shall not be under any further
liability.  If more than one (1) beneficiary is designated, then each
beneficiary shall receive the portion designated to be received by such
beneficiary by the Participant, or if no such designation is made, each
beneficiary shall receive an equal portion of the Shares and proceeds in the
account, provided that the Corporation may, in its sole discretion, make
adjustments in such distributions to avoid the issuance of fractional shares.

                 10.      Administration of the Plan.  The Plan will be
administered by the Committee.  The Committee shall have the full power,
discretion, and authority to interpret and administer the Plan consistent with
the Plan provisions and to delegate to employees of the Corporation or any
Parent or Subsidiary the authority to perform administrative functions under
the Plan.  The Committee shall serve at the pleasure of the Board of Directors.
A majority of the Committee shall constitute a quorum, and the acts of a
majority of the members of the Committee present at any meeting at which a
quorum is present, or acts approved in writing by a majority of the members of
the Committee, shall be deemed the acts of the Committee.  All costs and
expenses incurred in administering the Plan shall be paid by the Corporation.
Any taxes applicable to a Participant's account shall be charged or credited to
the Participant's account by the Corporation.

                 11.      Modification and Termination.  Although the
Corporation expects to continue the Plan until such time as all of the Shares
reserved for issuance under the Plan have been sold, the Board and/or the
Committee reserve the right to amend, alter, suspend, discontinue

or terminate the Plan in its or their discretion; provided, however, that the
Board, shall not, without the approval of the shareholders of the Corporation
(i) increase the maximum number of Shares which may issued under the Plan
(except pursuant to Section 12 hereof) or (ii) amend the requirements as to the
class of employees eligible to purchase Shares under the Plan.  The Board may,
in its discretion, submit any proposed amendment to the Plan to the
shareholders of the Corporation for approval and shall submit proposed
amendments to the Plan to the shareholders of the Corporation for approval if
such approval is required in order for the Plan to comply with Rule 16b-3 of
the Exchange Act (or any successor rule).  In the event shareholder approval of
the Plan is not obtained prior to the date that is twelve (12) months after the
date this Plan is adopted by the Board, the Plan shall terminate.  Upon such
termination, each Participant shall be entitled to payment of the amount of his
or her individual account within thirty (30) days after the date of termination
of the Plan and no Shares shall be issued to any Employee hereunder.

                 12.      Adjustments Upon Changes in Capitalization.
Appropriate and proportionate adjustments shall be made in the number and class
of shares of stock subject to this Plan in the event of a stock dividend, stock
split, reverse stock split, recapitalization, reorganization, merger,
consolidation, acquisition, separation or like change in the capital structure
of the Corporation.

                 13.      Transferability of Rights.  No rights of any Employee
under this Plan shall be transferable by such Employee, by operation of law or
otherwise, except (a) to the extent that a Participant is permitted to
designate a beneficiary or beneficiaries as hereinabove provided, (b) to the
extent permitted by will or the laws of descent and distribution if no such
beneficiary has been designated and (c) pursuant to a qualified domestic
relations order as defined in Section 414(p) of the Code or Title I of the
Employee Retirement Income Security Act of 1974, as amended.  Except as set
forth above, purchase options granted under this Plan are exercisable, during
an Employee's lifetime, only by the Employee.

                 14.      Participation in Other Plans.  Nothing herein
contained shall affect an Employee's right to participate in and receive
benefits under and in accordance with the then current provisions of any
pension, insurance or other employee welfare plan or program of the
Corporation.

                 15.      Compliance with Governmental Regulations.
Notwithstanding any provision of the Plan or the terms of any agreement entered
into pursuant to the Plan, the Corporation shall not be required to issue any
shares hereunder prior to registration of the shares subject to the Plan under
the Securities Act of 1933, as amended, or the Exchange Act, if such
registration shall be necessary, or before compliance by the Corporation or any
Participant with any other provisions of either of those acts or of regulations
or rulings of the Securities and Exchange Commission thereunder, or before
compliance with other federal and state laws and regulations and rulings
thereunder, including the rules of the National Association of Securities
Dealers, Inc.  The Corporation shall use its best efforts to effect such
registrations and to comply with such laws, regulations and rulings forthwith
upon advice by its counsel that any such registration or compliance is
necessary.

                 16.      Compliance with Rule 16b-3.  It is the intent of the
Corporation that this Plan and all transactions under this Plan comply in all
respects with applicable provisions of Rule 16b-3 under the Exchange Act (or
any successor rule).  Accordingly, if any provision of this Plan, any agreement
hereunder, or any transaction pursuant to the Plan does not comply with the
requirements of Rule 16b-3 as then applicable to a Participant, such provisions
will be construed or deemed amended to the extent necessary to conform to the
applicable requirements with respect to such Participant.  To the extent that

shareholder of the Corporation unless and until shares of Common Stock are in
fact issued to such Participant (or person).

                 19.      Governing Law.  To the extent not preempted by
Federal law, the Plan and any agreement pursuant to the Plan shall be construed
in accordance with and governed by the internal laws of the State of
California.

                 20.      Severability.  In the event any provision of the Plan
or any action taken pursuant to the Plan shall be held illegal or invalid for
any reason, the illegality or invalidity shall not affect the remaining parts
of the Plan, and the Plan shall be construed and enforced as if the illegal or
invalid provision had not been included, and the illegal or invalid action
shall be deemed null and void.

                 21.      Withholding Taxes.  To the extent required by
applicable law or regulation, each Employee must arrange with the Corporation
for the payment of any federal, state or local income or other tax applicable
to the receipt of Common Stock under the Plan before the Corporation shall be
required to deliver to the Employee a certificate for Shares of Common Stock.
