               - A Qualifying Employee who was not eligible to enter an Option
        Period on the first day of the Option Period may enter that Option

        accordance with Section V.C below.

               B. A Qualifying Employee who does not enroll for an Option Period

               C. To enroll in the Plan, a Qualifying Employee must complete the

is changed in accordance with the following guidelines:

                      - The Participant may, at any time during a Purchase
        Period, reduce the rate of payroll deduction. Such reduction shall
        become effective as soon as possible after filing of the requisite
        reduction form with the Plan Administrator (or its designate), but the
        Participant may not effect more than one such reduction during the same
        Purchase Period.

                      - The Participant may, prior to the commencement of any
        new Purchase Period within the Option Period, increase or decrease the
        rate of payroll deduction for the new Purchase Period by filing the
        appropriate form with the Plan Administrator (or its designate). The new
        rate shall become effective as of the first day of the next Purchase
        Period.

                  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 maximum number of shares of Common Stock which may be

               B. In the event any change is made to the Company's outstanding
Common Stock by reason of any stock dividend, stock split, combination of shares
or other change affecting such outstanding Common Stock as a class without
receipt of consideration, then appropriate adjustments shall be made by the Plan
Administrator to (i) the class and maximum number of shares issuable over the
term of the Plan, (ii) the class and maximum number of shares purchasable per
Participant during any one Option Period and (iii) the class and number of
shares 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.

        VII.   PURCHASE RIGHTS

               Each Participant in a particular Option Period shall have the
right to purchase shares of Common Stock at the close of each Purchase Period
during such Option Period on the terms and conditions set forth below (the
"Purchase Rights"). Each Participant shall execute a purchase agreement
embodying such terms and conditions and such other provisions (not inconsistent
with the Plan) as the Plan Administrator may require.

               Purchase Price. The Purchase Rights shall be exercised at the end
of each Purchase Period at a purchase price equal to eighty-five percent (85%)
of the lower of (i) the fair market value per share of the Common Stock on the
Participant's Entry Date or (ii) the fair market value per share of the Common
Stock on the last business day of the Purchase Period. However, for each
Participant whose Entry Date is other than the first day of the Option Period,
the amount determined under clause (i) shall not be less than 85% of the fair
market value of the Common Stock on the first day of such Option Period.

               Valuation. For purposes of determining the fair market value per
share of Common Stock on any relevant date, the following procedures shall be in
effect:

               - If fair market value is to be determined on a day on which the
               Common Stock being actively traded through the Nasdaq National
               Market or any national securities exchange, then the fair market
               value shall be the closing selling price on that date, as
               officially quoted on the Nasdaq National Market or national
               securities exchange, or if there is no quoted selling price for
               such date, then the closing selling price on the next preceding
               day for which there does exist such a quotation.

               - If fair market value is to be determined prior to such Section
               12(g) registration of the Common Stock, then the fair market
               value of the Common Stock on such date shall be determined by the
               Plan Administrator after taking into account such factors as the
               Plan Administrator deems appropriate.


                                      -5-
   7

               Number of Purchasable Shares. The number of shares purchasable by
a Participant each Purchase Period shall be the number of whole shares obtained
by dividing the amount in Participant's Account at the end of such Purchase
Period by the purchase price in effect for the Purchase Period. Notwithstanding
the above, no Participant shall have the right to purchase shares of Common
Stock to the extent that, immediately after the grant, such Participant would
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 Company or
any of its Corporate Affiliates.

               Payment. Payment for the 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 full pay period following the
Effective Date following the Participant's Entry Date into the Option 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 Option Period. The
amounts so collected shall be credited to the Participant's Account under the
Plan, but no interest shall be paid on the balance from time to time outstanding
in such Account. The amounts collected from a Participant may be commingled with
the general assets of the Company and may be used for general corporate
purposes.

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

                        (i) A Participant may, at any time prior to the last
          five (5) business days of the Purchase Period, terminate his/her
          outstanding purchase right 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 current Purchase Period shall, at the
          Participant's election, be immediately refunded or held for the
          purchase of shares on the end of the Purchase Period. If no such
          election is made, then such funds shall be refunded as soon as
          possible after the close of such Purchase Period.

                        (ii) After the termination of purchase rights for an
          Option Period, the Participant may not subsequently rejoin that Option
          Period. In order to resume participation in any subsequent Option
          Period, such individual must re-enroll in the Plan for that Option
          Period.

                         (iii) If a Participant ceases to be a Qualifying
        Employee for any reason whatsoever during an Option Period then all
        payroll deductions shall terminate and all funds held in the
        Participant's Account will be promptly paid to the Participant or the
        Participant's legal representative. 


                                      -6-
   8

          No further purchases of shares hereunder shall occur after the
          Participant has ceased to be a Qualifying Employee.

               Stock Purchase. Subject to the limitations set forth herein,
funds held in a Participant's Account at the end of a Purchase Period (and which
are not required to be refunded hereunder) shall be applied to the purchase of
whole shares of Common Stock for the Participant on the last business day of the
Purchase Period at the purchase price in effect for such Purchase Period. 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 in the
next Purchase Period. Any payroll deductions not applied to the purchase of
Common Stock for any other reason shall be promptly refunded to the Participant.

               Proration of Purchase Rights. If the total number of shares of
Common Stock which would otherwise be purchased hereunder on any 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 to
Participants on a uniform and nondiscriminatory basis.

               Rights as Shareholder. A Participant shall have no shareholder
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 purchase hereunder, a stock certificate for the number of
shares purchased for the Participant. 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.

               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.

               Change in Ownership. Should the Company or its shareholders enter
into an agreement to dispose of all or substantially all of the assets or
outstanding capital stock of the Company by means of:

                      (i)     a sale, merger or other reorganization in which 
          the Company will not be the surviving corporation (other than a
          reorganization effected primarily to change the State in which the
          Company is incorporated), or


                                      -7-
   9

                        (ii)  a reverse merger in which the Company is the
          surviving corporation but in which more than 50% of the Company's
          outstanding voting stock is transferred to holders different from
          those who held the stock immediately prior to the reverse merger,

               then all outstanding purchase rights under the Plan shall
automatically be exercised immediately prior to the consummation of such sale,
merger, reorganization or reverse merger by applying the amounts in each
Participant's Account to the purchase of whole shares of Common Stock at
eighty-five percent (85%) of the lower of (i) the fair market value of the
Common Stock on the Participant's Entry Date into the Option Period in which
such transaction occurs or (ii) the fair market value of the Common Stock
immediately prior to the consummation of such transaction. However, the
applicable share limitations of Articles VII and VIII shall continue to apply to
any such purchase, and the clause (i) amount above shall not, for any
Participant whose Entry Date for the Option Period is other than the start date
of such Option Period, be less than the fair market value of the Common Stock on
such start date.

               The Company shall use its best efforts to provide at least ten
(10)-days advance written notice of the occurrence of any such sale, merger,
reorganization or reverse merger, 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 Company or its Corporate Affiliates,
would otherwise permit such Participant to purchase more than $25,000 worth of
stock of the Company 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 to
the Participant) 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:

                        (i) 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 


                                      -8-
   10

          semi-annual installment on the last business day of each Purchase
          Period for which the right remains outstanding.

                        (ii)  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 the right to acquire
          $25,000 worth of Common Stock (determined on the basis of the fair
          market value on the date or dates of grant) pursuant to one or more
          purchase rights held by the Participant during such calendar year.

                        (iii) If by reason of such accrual limitations, any
          purchase right of a Participant does not accrue for a particular
          Purchase Period, then the payroll deductions which the Participant
          made during that Purchase Period 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 or more provisions of the Plan or any instrument
issued thereunder, the provisions of this Article VIII shall be controlling.

        IX.    STATUS OF PLAN UNDER FEDERAL TAX LAWS

               The Plan is designed to qualify as an employee stock purchase
plan under Code Section 423.

        X.     AMENDMENT AND TERMINATION

               A. The Board may alter, amend, suspend or discontinue the Plan
following the close of any Purchase Period. However, the Board may not, without
the approval of the Company's shareholders:

                        (i) materially increase the number of shares issuable
          under the Plan or the maximum number of shares which may be purchased
          per Participant during any one Option Period under the Plan, except
          that the Plan Administrator shall have the authority, exercisable
          without such shareholder approval, to effect adjustments to the extent
          necessary to reflect changes in the Company's capital structure
          pursuant to Section VI.B;

                        (ii) alter the purchase price formula so as to reduce
          the purchase price payable for the shares issuable under the Plan; or


                                      -9-
   11

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

               B. The Company 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 Purchase Period.
Should the Company 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.
