Section 423. Decisions of the Plan Administrator shall be final and binding on
all parties who have an interest in the Plan.


      IV.   OFFERING PERIODS
            ----------------

      A.    Shares of Common Stock shall be offered for purchase under the Plan
through a series of successive or overlapping Offering Periods until such time
as (i) the maximum number of shares of Common Stock available for issuance under
the Plan shall have been purchased or (ii) the Plan shall have been sooner
terminated in accordance with Subsection I of Article VII, Subsection A of
Article IX or Subsection B of Article X.

      B.    Each Offering Period shall have a maximum duration of twenty-four
(24) months. The duration of each Offering Period shall be designated by the
Plan Administrator prior to the start date. However, the initial Offering Period
shall run from the Effective Time to the last business day of July 1998. The
next Offering Period shall commence on the first business day of February 1997
and continue through the last business day of January 1999, and subsequent

Offering Period in which he or she participates, and each Participant may
participate in more than one (1) Offering Period at any one time. Accordingly, a
Participant may continue to participate in one Offering Period and also enroll
in subsequent Offering Periods. The purchase right shall be granted on the date
such individual first joins an Offering Period in effect under the Plan and
shall be automatically exercised in successive semi-annual installments on the
last business day of January and July of each year. Accordingly, each purchase
right may be exercised up to two (2) times each year it remains outstanding. In
the event that the Fair Market Value of the Common Stock on the last trading day
before the commencement of the Offering Period for which the Participant is
enrolled is higher than on the last trading day before the commencement of any
subsequent Offering Period, the Participant shall automatically be re-enrolled
for such subsequent Offering Period. In addition, any other provision of the
Plan notwithstanding, the

                                       3
<PAGE>

Corporation (at its sole discretion) may determine prior to the commencement of
any new Offering Period that all Participants shall be re-enrolled for such new
Offering Period. When a Participant reaches the end of an Offering Period but
his or her participation is to continue, then such Participant shall
automatically be re-enrolled for the Offering Period that commences immediately
after the end of the prior Offering Period.

      D.    No purchase rights granted under the Plan shall be exercised, and no
shares of Common Stock shall be issued hereunder, until such time as (i) the
Plan shall have been approved by the stockholders of the Corporation and (ii)
the Corporation shall have complied with all applicable requirements of the 1933
Act (including the registration of the shares of Common Stock issuable under the
Plan on a Form S-8 registration statement filed with the Securities and Exchange
Commission), all applicable listing requirements of any securities exchange on
which the Common Stock is listed for trading and all other applicable
requirements established by law or regulation.

      E.    The Participant's acquisition of Common Stock under the Plan on any
Semi-Annual Purchase Date shall neither limit nor require the Participant's
acquisition of Common Stock on any subsequent Semi-Annual Purchase Date, whether
within the same or a different Offering Period.

      V.    ELIGIBILITY AND PARTICIPATION
            -----------------------------

      A.    Each Eligible Employee of a Participating Corporation shall be
eligible to participate in the Plan in accordance with the following provisions:

         .  An individual who is an Eligible Employee on the start date of any
            Offering Period under the Plan shall be eligible to commence
            participation in that Offering Period on such start date.

         .  An individual who first becomes an Eligible Employee after the start
            date of any Offering Period under the Plan may enter any subsequent
            Offering Period on which he/she remains an Eligible Employee.

      B.    In order to participate in the Plan for a particular Offering
Period, the Eligible Employee must complete the enrollment forms prescribed by
the Plan Administrator (including a purchase agreement and a payroll deduction
authorization) and file such forms with the Plan Administrator (or its
designate) on or before the start date for such Offering Period.

      C.    The payroll deduction authorized by the Participant for purposes of
acquiring shares of Common Stock under the Plan may be any multiple of one
percent (1%) of the Cash Compensation paid to the Participant during each
Semi-Annual Period of Participation within the Offering Period, up to a maximum
of fifteen percent (15%). However, if a Participant is participating in more
than one Offering Period at any one time, the maximum authorized payroll
deduction under the Plan remains fifteen percent (15%). The deduction rate so
authorized shall

                                       4
<PAGE>

continue in effect for the remainder of the Offering Period, except to the
extent such rate is changed in accordance with the following guidelines:

         .  The Participant may, at any time during a Semi-Annual Period of
            Participation, reduce his/her rate of payroll deduction to become
            effective as soon as possible after filing of the requisite
            reduction form with the Plan Administrator. The Participant may not,
            however, effect more than one (1) such reduction per Semi-Annual
            Period of Participation.

         .  The Participant may, prior to the commencement of any new Semi-
            Annual Period of Participation within the Offering Period, increase
            the rate of his/her payroll deduction by filing the appropriate form
            with the Plan Administrator. The new rate (which may not exceed the
            fifteen percent (15%) maximum) shall become effective as of the
            first day of the first Semi-Annual Period of Participation following
            the filing of such form. If the Participant is participating in more
            than one Offering Period and Participant elects to increase his or
            her payroll deduction in any one Offering Period, the payroll
            deduction applicable to any other Offering Period shall be
            automatically reduced, such that the maximum payroll deduction for
            all concurrent Offering Periods remains fifteen percent (15%).

     D.     In no event may any Participant's payroll deductions for any one
Semi-Annual Period of Participation exceed Ten Thousand Dollars ($10,000.00).

     E.     Payroll deductions will automatically cease upon the termination of
the Participant's purchase right in accordance with the applicable provisions of
Section VII below.

     VI.    STOCK SUBJECT TO PLAN
            ---------------------

     A.     The Common Stock purchasable by Participants under the Plan shall,
solely in the discretion of the Plan Administrator, be made available from
either authorized but unissued shares of Common Stock or from shares of Common
Stock reacquired by the Corporation, including shares of Common Stock purchased
on the open market. The total number of shares which may be issued in the
aggregate under the Plan shall not exceed One Million Six Hundred Thousand
(1,600,000) shares (subject to adjustment under Section VI.B below).

     B.     In the event any change is made to the Corporation's outstanding
Common Stock by reason of any stock dividend, stock split, exchange or
combination of shares, recapitalization or any other change affecting the Common
Stock as a class without the Corporation's receipt of consideration, appropriate
adjustments shall be made by the Plan Administrator to (i) the class and maximum
number of securities issuable over the term of the Plan, (ii) the class and
maximum number of securities purchasable per Participant on any one (1)
Semi-Annual Purchase Date and (iii) the class and number of securities and the
price per share in effect under each purchase right at the time outstanding
under the Plan. Such adjustments shall be designed to preclude the dilution or
enlargement of rights and benefits under the Plan.

                                       5
<PAGE>

         VII.     PURCHASE RIGHTS
                  ---------------

         Each Eligible Employee who participates in the Plan for a particular
Offering Period shall have the right to purchase shares of Common Stock, in a
series of successive semi-annual installments during such Offering Period, upon
the terms and conditions set forth below and shall execute a purchase agreement
embodying such terms and conditions and such other provisions (not inconsistent
with the Plan) as the Plan Administrator may deem advisable.

         A.  Purchase Price. Common Stock shall be purchasable on each Semi-
             --------------
Annual Purchase Date within the Offering Period at a purchase price equal to
eighty-five percent (85%) of the lower of (i) the Fair Market Value per share of
                                 ----
Common Stock on the Participant's commencement date into that Offering Period or
(ii) the Fair Market Value per share on that Semi-Annual Purchase Date.

         B.  Number of Purchasable Shares. The number of shares purchasable per
             ----------------------------
Participant on each Semi-Annual Purchase Date during the Offering Period shall
be the number of whole shares obtained by dividing the amount collected from the
Participant through payroll deductions during the Semi-Annual Period of
Participation ending with that Semi-Annual Purchase Date (together with any
carryover deductions from the preceding Semi-Annual Period of Participation) by
the purchase price in effect for the Semi-Annual Purchase Date (as determined in
accordance with Subsection A above). However, the maximum number of shares of
Common Stock purchasable per Participant on any Semi-Annual Purchase Date shall
not exceed Two Thousand (2,000) shares, subject to periodic adjustment under
Section VI.B.

         Under no circumstances shall purchase rights be granted under the Plan
to any Eligible Employee if such individual would, immediately after the grant,
own (within the meaning of Code Section 424(d)) or hold outstanding options or
other rights to purchase, stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Corporation
or any of its Corporate Affiliates.

         C.  Payment. Payment for Common Stock purchased under the Plan shall be
             -------
effected by means of the Participant's authorized payroll deductions. Such
deductions shall begin with the first pay day following the Participant's
commencement into the Offering Period and shall (unless sooner terminated by the
Participant) continue through the pay day ending with or immediately prior to
the last day of the Offering Period. The amounts so collected shall be credited
to the Participant's book account under the Plan, but no interest shall be paid
on the outstanding balance credited to such account. The amounts collected from
a Participant will not be held in any segregated account or trust fund and may
be commingled with the general assets of the Corporation and used for general
corporate purposes.

         D.  Termination of Purchase Right. The following provisions shall
             -----------------------------
govern the termination of outstanding purchase rights:

                                       6
<PAGE>

         .  A Participant may, at any time prior to the last five (5) business
            days of the next Semi-Annual Purchase Date, terminate his/her
            outstanding purchase right(s) under the Plan by filing the
            prescribed notification form with the Plan Administrator (or its
            designate). No further payroll deductions shall be collected from
            the Participant with respect to the terminated purchase right, and
            any payroll deductions collected for the Semi-Annual Period of
            Participation in which such termination occurs shall, at the
            Participant's election, be immediately refunded or held for the
            purchase of shares on the Semi-Annual Purchase Date immediately
            following such termination. If no such election is made at the time
            such purchase right is terminated, then the payroll deductions
            collected with respect to the terminated right shall be refunded as
            soon as possible.

         .  The termination of such purchase right shall be irrevocable, and a
            Participant may not subsequently rejoin the Offering Period for
            which the terminated purchase right was granted. In order to resume
            participation in any subsequent Offering Period, such individual
            must re-enroll in the Plan (by making a timely filing of a new stock
            purchase agreement and enrollment form) on or before the date he or
            she is first eligible to join the new Offering Period.

         .  Should a Participant cease to remain an Eligible Employee for any
            reason (including death, disability or change in status) while
            his/her purchase right(s) remains outstanding, then such purchase
            right(s) shall immediately terminate, and such individual (or the
            personal representative of the estate of a deceased Participant)
            shall have the following election with respect to the payroll
            deductions made to date in the Semi-Annual Period of Participation
            in which such cessation of Eligible Employee status occurs:

            1)   to withdraw all of those deductions, or

            2)   to have such funds held for the purchase of shares at the end
of the Semi-Annual Period of Participation.

     If no such election is made within the thirty (30)-day period following
such cessation of Eligible Employee status or (if earlier) prior to the last day
of the Semi-Annual Period of Participation, then the collected payroll
deductions shall be refunded as soon as possible. In no event, however, may any
payroll deductions be made on the Participant's behalf following his/her
cessation of Eligible Employee status. If a Participant's ceases Eligible
Employee status more than three (3) months prior to the last day of the Semi-
Annual Period of Participation and elects to have funds held for the purchase of
shares on such last date, then the Participant shall be required to satisfy all
income and employment tax withholding requirements applicable to such purchase.

     E.     Stock Purchase. Shares of Common Stock shall automatically be
            --------------
purchased on behalf of each Participant (other than Participants whose payroll
deductions have previously been

                                       7
<PAGE>

refunded in accordance with the Termination of Purchase Right provisions in
Subsection D above) on each Semi-Annual Purchase Date. The purchase shall be
effected by applying each Participant's payroll deductions for the Semi-Annual
Period of Participation ending on such Semi-Annual Purchase Date (together with
any carryover deductions from the preceding Semi-Annual Period of Participation)
to the purchase of whole shares of Common Stock (subject to the limitation on
the maximum number of purchasable shares imposed under Subsection B of this
Article VII) at the purchase price in effect for that Semi-Annual Purchase Date.
Any payroll deductions not applied to such purchase because they are not
sufficient to purchase a whole share shall be held for the purchase of Common
Stock on the next Semi-Annual Purchase Date. However, any payroll deductions not
applied to the purchase of Common Stock by reason of the limitation on the
maximum number of shares purchasable by the Participant on the Semi-Annual
Purchase Date shall be promptly refunded to the Participant.

     F.   Proration of Purchase Rights. Should the total number of shares of
          ----------------------------
Common Stock which are to be purchased pursuant to outstanding purchase rights
on any particular date exceed the number of shares then available for issuance
under the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded to such Participant.

     G.   Rights as Stockholder. A Participant shall have no stockholder rights
          ----------------------
with respect to the shares subject to his/her outstanding purchase right until
the shares are actually purchased on the Participant's behalf in accordance with
the applicable provisions of the Plan. No adjustments shall be made for
dividends, distributions or other rights for which the record date is prior to
the date of such purchase.

     A Participant shall be entitled to receive, as soon as practicable after
each Semi-Annual Purchase Date, a stock certificate for the number of shares
purchased on the Participant's behalf. Such certificate may, upon the
Participant's request, be issued in the names of the Participant and his/her
spouse as community property or as joint tenants with right of survivorship.
Alternatively, the Corporation may provide for the issuance of such certificate
in "street name" for immediate deposit in a Corporation-designated brokerage
account established by the Participant.

     H.   Assignability. No purchase right granted under the Plan shall be
          -------------
assignable or transferable by the Participant other than by will or by the laws
of descent and distribution following the Participant's death, and during the
Participant's lifetime the purchase right shall be exercisable only by the
Participant.

     I.   Corporate Transaction. Should any of the following transactions (a
          ---------------------
"Corporate Transaction") occur during the Offering Period:

          (i)  a merger or consolidation in which securities possessing
more than fifty percent (50%) of the total combined voting power of the
Corporation's outstanding securities are

                                       8
<PAGE>

transferred to a person or persons different from the persons holding those
securities immediately prior to such transaction, or

               (ii)    the sale, transfer or other disposition of all or
substantially all of the assets of the Corporation in complete liquidation or
dissolution of the Corporation.

then each outstanding purchase right shall automatically be exercised,
immediately prior to the effective date of any Corporate Transaction, by
applying the payroll deductions of each Participant for the Semi-Annual Period
of Participation in which such Corporate Transaction occurs to the purchase of
whole shares of Common Stock at a purchase price per share equal to eighty-five
percent (85%) of the lower of (i) the Fair Market Value per share of Common
                     -----
Stock on the Participant's commencement date into the offering period in which
such Corporate Transaction occurs or (ii) the Fair Market Value per share of
Common Stock immediately prior to the effective date of such Corporate
Transaction. However, the applicable limitation on the number of shares of
Common Stock purchasable per Participant shall continue to apply to any such
purchase.

     The Corporation shall use its best efforts to provide at least ten (10)-
days prior written notice of the occurrence of any Corporate Transaction, and
Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights in accordance with the applicable
provisions of this Article VII.


     VIII.     ACCRUAL LIMITATIONS
               -------------------

     A.    No Participant shall be entitled to accrue rights to acquire Common
Stock pursuant to any purchase right outstanding under this Plan if and to the
extent such accrual, when aggregated with (i) rights to purchase Common Stock
accrued under any other purchase right outstanding under this Plan and (ii)
similar rights accrued under other employee stock purchase plans (within the
meaning of Code Section 423) of the Corporation or its Corporate Affiliates,
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value of such stock on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

     B.    For purposes of applying such accrual limitations, the right to
acquire Common Stock pursuant to each purchase right outstanding under the Plan
shall accrue as follows:

        .  The right to acquire Common Stock under each such purchase right
           shall accrue in a series of successive semi-annual installments as
           and when the purchase right first becomes exercisable for each such
           installment on the last business day of each Semi-Annual Period of
           Participation for which the right remains outstanding.

        .  No right to acquire Common Stock under any outstanding
           purchase right shall accrue to the extent the Participant has
           already accrued in the same calendar year

                                       9
<PAGE>

           the right to acquire Common Stock under one (1) or more other
           purchase rights at a rate equal to Twenty-Five Thousand Dollars
           ($25,000) worth of Common Stock (determined on the basis of the Fair
           Market Value on the date or dates of grant) for each calendar year
           during which one (1) or more of those purchase rights were at any
           time outstanding.

        .  If by reason of such accrual limitations, any purchase right of a
           Participant does not accrue for a particular Semi-Annual Period of
           Participation, then the payroll deductions which the Participant made
           during that Semi-Annual Period of Participation with respect to such
           purchase right shall be promptly refunded.

     C.    In the event there is any conflict between the provisions of this
Article VIII and one (1) or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article VIII shall be controlling.

     IX.   AMENDMENT AND TERMINATION
           -------------------------

     A.    The Board may alter, amend, suspend or discontinue the Plan following
the close of any Semi-Annual Period of Participation. However, the Board may
not, without the approval of the Corporation's stockholders:

        .  materially increase the number of shares issuable under the Plan or
           the maximum number of shares purchasable per Participant on any one
           (1) Semi-Annual Purchase Date, except that the Plan Administrator
           shall have the authority, exercisable without such stockholder
           approval, to effect adjustments to the extent necessary to reflect
           changes in the Corporation's capital structure pursuant to Subsection
           B of Article VI; or

        .  alter the purchase price formula so as to reduce the purchase price
           payable for the shares purchasable under the Plan; or

        .  materially increase the benefits accruing to Participants under the
           Plan or materially modify the requirements for eligibility to
           participate in the Plan.

     B.    The Corporation shall have the right, exercisable in the sole
discretion of the Plan Administrator, to terminate all outstanding purchase
rights under the Plan immediately following the close of any Semi-Annual Period
of Participation. Should the Corporation elect to exercise such right, then the
Plan shall terminate in its entirety. No further purchase rights shall
thereafter be granted or exercised, and no further payroll deductions shall
thereafter be collected, under the Plan.
