     (a) Any person who qualifies or will qualify as an Eligible Employee on the

elect to participate by executing the participation agreement prescribed for
such purpose by the Plan Administrator. The participation agreement shall be
filed with the Plan Administrator no later than the deadline stated on the

of the Participation Period. The Eligible Employee shall designate on the
participation agreement the amount, of his or her Compensation which he or she
elects to have withheld for the purchase of Stock in the manner specified by the
Plan Administrator; provided that the amount may not be greater than ten percent
(10%) of the Participant's Compensation.

     (b) By enrolling in the Plan, a Participant shall be deemed to have elected
to purchase the maximum number of whole shares of Stock which can be purchased
with the amount of the Participant's Compensation which is withheld during the
Participation Period.

     (c) Once enrolled, a Participant will continue to participate in the Plan
for each succeeding Participation Period until he or she terminates
participation or ceases to qualify as an Eligible Employee. A Participant who
withdraws from the Plan in accordance with Section 10 may again become a
Participant, if he or she then is an Eligible Employee, by following the
procedure described in Section 5(a).

     Section 6.  Participation Periods.
     ----------  ----------------------

     The Plan shall be implemented by one or more Participation Periods of not
more than twenty-seven (27) months each. The Board of Directors, or a committee
to which the Board has delegated its authority, shall determine the commencement
date and duration of each Participation Period.

     Section 7.  Purchase Price.
     ----------  ---------------

     The Purchase Price for each share of Stock shall be the lesser of (i)
eighty-five percent (85%) of the Fair Market Value of such share on the last
trading day before the Date of Participation or (ii) eighty-five percent (85%)
of the Fair Market Value of such share on the last trading day during the
Participation Period.

     Section 8.  Employee Contributions.
     ----------  -----------------------

     A Participant may purchase shares of Stock solely by means of payroll
deductions. Payroll deductions, as designated by the Participant pursuant to
Section 5(a), shall commence with the first paycheck issued during the
Participation Period and shall be deducted from each subsequent paycheck
throughout the Participation Period. If a Participant desires to decrease the
rate of payroll withholding during the Participation Period, he or she may do
so, if permitted by

                                      -3-




the Plan Administrator, one time during a Participation Period by filing a
new participation agreement with the Plan Administrator. Such decrease will be
effective as of the first day of the second payroll period which begins
following the receipt of the new participation agreement. If a Participant
desires to increase the rate of payroll withholding, he or she may do so
effective for the next Participation Period by filing a new participation
agreement with the Plan Administrator on or before the date specified by the
Plan Administrator, and if none is stated, then no later than the first day of
the Participation Period for which such change is to be effective.

     Section 9.  Plan Accounts; Purchase of Shares.
     ----------  ----------------------------------

     (a) The Company will maintain a Plan Account on its books in the name of
each Participant. At the close of each pay period, the amount deducted from the
Participant's Compensation will be credited to the Participant's Plan Account.

     (b) As of the last day of each Participation Period, the amount then in the
Participant's Plan Account will be divided by the Purchase Price, and the number
of whole shares which results (subject to the limitations described in Sections
5(b), 9(c) and 14) shall be purchased from the Company with the funds in the
Participant's Plan Account. Share certificates representing the number of shares
of Stock so purchased shall be delivered to the Plan Administrator pursuant to a
participation agreement between each Participant and the Company and subject to
the conditions described therein which may include a requirement that shares of
Stock be held and not sold for certain time periods.

     (c) In the event that the aggregate number of shares which all Participants
elect to purchase during a Participation Period shall exceed the number of
shares remaining available for issuance under the Plan, then the number of
shares to which each Participant shall become entitled shall be determined by
multiplying the number of shares available for issuance by a fraction the
numerator of which is the sum of the number of shares the Participant has
elected to purchase pursuant to Section 5, and the denominator of which is the
sum of the number of shares which all employees have elected to purchase
pursuant to Section 5. Any cash amount remaining in the Participant's Plan
Account under these circumstances shall be refunded to the Participant.

     (d) Any amount remaining in the Participant's Plan Account caused by a
surplus due to fractional shares after deducting the amount of the Purchase
Price for the number of whole shares issued to the Participant shall be carried
over in the Participant's Plan Account for the succeeding Participation Period,
without interest. Any amount remaining in the Participant's Plan Account caused
by anything other than a surplus due to fractional shares shall be refunded to
the Participant in cash, without interest.

     (e) As soon as practicable following the end of each Participation Period,
the Company shall deliver to each Participant a Plan Account statement setting
forth the amount of payroll deductions, the purchase price, the number of shares
purchased and the remaining cash balance, if any.

                                      -4-




     Section 10.  Withdrawal From the Plan.
     -----------  -------------------------

     A Participant may elect to withdraw from participation under the Plan at
any time up to the last day of a Participation Period by filing the prescribed
form with the Plan Administrator. As soon as practicable after a withdrawal,
payroll deductions shall cease and all amounts credited to the Participant's
Plan Account will be refunded in cash, without interest. A Participant who has
withdrawn from the Plan shall not be a Participant in future Participation
Periods, unless he or she again enrolls in accordance with the provisions of
Section 5.

     Section 11.  Effect of Termination of Employment or Death.
     -----------  ---------------------------------------------

     (a) Termination of employment as an Eligible Employee for any reason,
including death, shall be treated as an automatic withdrawal from the Plan under
Section 10. A transfer from one Participating Company to another shall not be
treated as a termination of employment.

     (b) A Participant may file a written designation of a beneficiary who is to
receive any shares and cash, if any, from the Participant's Account under the
Plan in the event of such Participant's death subsequent to the purchase of
shares but prior to delivery to him of such shares and cash. In addition, a
Participant may file a written designation of a beneficiary who is to receive
any cash from the Participant's Account under the Plan in the event of such
Participant's death prior to the last day of a Participation Period.

     (c) Such designation of beneficiary may be changed by the Participant at
any time by written notice. In the event of the death of a Participant in the
absence of a valid designation of a beneficiary who is living at the time of
such Participant's death, the Company shall deliver such shares and/or cash to
the executor or administrator of the estate of the Participant; or if no such
executor or administrator has been appointed (to the knowledge of the Company),
the Company, in its discretion, may deliver such shares and/or cash to the
spouse or to any one or more dependents or relatives of the Participant; or if
no spouse, dependent or relative is known to the Company, then to such other
person as the Company may designate.

     Section 12.  Rights Not Transferable.
     -----------  ------------------------

     The rights or interests of any Participant in the Plan, or in any Stock or
moneys to which he or she may be entitled under the Plan, shall not be
transferable by voluntary or involuntary assignment or by operation of law, or
by any other manner other than as permitted by the Code or by will or the laws
of descent and distribution. If a Participant in any manner attempts to
transfer, assign or otherwise encumber his or her rights or interest under the
Plan, other than as permitted by the Code or by will or the laws of descent and
distribution, such act shall be treated as an automatic withdrawal under Section
10.

     Section 13.  Recapitalization, Etc.
     -----------  ----------------------

     (a) The aggregate number of shares of Stock offered under the Plan, the
number and price of shares which any Participant has elected to purchase
pursuant to Section 5 and the maximum number of shares which a Participant may
elect to purchase under the Plan in any Participation Period shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Stock resulting from a subdivision or consolidation of shares or any
other

                                      -5-



capital adjustment, the payment of a stock dividend, or other increase or
decrease in such shares effected without receipt of consideration by the
Company.

     (b) In the event of a dissolution or liquidation of the Company, or a
merger or consolidation to which the Company is a constituent corporation, this
Plan shall terminate, unless the plan of merger, consolidation or reorganization
provides otherwise, and all amounts which each Participant has paid towards the
Purchase Price of Stock hereunder shall be refunded, without interest.

     (c) The Plan shall in no event be construed to restrict in any way the
Company's right to undertake a dissolution, liquidation, merger, consolidation
or other reorganization.

     Section 14.  Limitation on Stock Ownership.
     -----------  ------------------------------

     Notwithstanding any provision herein to the contrary, no Participant shall
be permitted to elect to participate in the Plan (i) if such Participant,
immediately after his or her election to participate, would own stock possessing
five percent (5%) or more of the total combined voting power or value of all
classes of stock of the Company or any parent or Subsidiary of the Company, or
(ii) if under the terms of the Plan the rights of the Employee to purchase Stock
under this Plan and all other qualified employee stock purchase plans of the
Company or its Subsidiaries would accrue at a rate which exceeds twenty-five
thousand dollars ($25,000) of the Fair Market Value of such Stock (determined at
the time such right is granted) for each calendar year for which such right is
outstanding at any time. For purposes of this Section 14, ownership of stock
shall be determined by the attribution rules of Section 424(d) of the Code, and
Participants shall be considered to own any stock which they have a right to
purchase under this or any other stock plan.

     Section 15.  No Rights as an Employee.
     -----------  -------------------------

     Nothing in the Plan shall be construed to give any person the right to
remain in the employ of a Participating Company. Each Participating Company
reserves the right to terminate the employment of any person at any time and for
any reason.

     Section 16.  Rights as a Stockholder.
     -----------  ------------------------

     A Participant shall have no rights as a stockholder with respect to any
shares he or she may have a right to purchase under the Plan until the date of
issuance of a stock certificate pursuant to Section 9(b), subject to the
stockholders approval of the adoption of the Plan.

     Section 17.  Use of Funds.
     -----------  -------------

     All payroll deductions received or held by the Company under the Plan may
be used by the Company for any corporate purpose, and the Company shall not be
obligated to segregate such payroll deductions in separate accounts.

                                      -6-




     Section 18.  Amendment or Termination of the Plan.
     -----------  -------------------------------------

     The Board of Directors shall have the right to amend, modify or
terminate the Plan at any time without notice. An amendment of the Plan shall be
subject to stockholder  approval only to the extent required by applicable laws,
regulations or rules.

     Section 19.  Governing Law.
     -----------  --------------

     The Plan shall be governed by, and construed and interpreted in accordance
with, the laws of the State of California.

     To record the adoption of the Plan by the Board of Directors, effective as

caused its authorized officer to execute the same on February 27, 1997.
