               (b)  Any provisions of the Plan to the contrary notwithstanding,
no Employee shall be granted an option under the Plan (i) to the extent that,
immediately after the grant, such Employee (or any other person whose stock

overlapping Offering Periods with a new Offering Period commencing on the first
Trading Day on or after September 1 and March 1 each year, or on such other date
as the Board shall determine, and continuing thereafter until terminated in

duration of Offering Periods and Purchase Periods (including the commencement
dates thereof) with respect to future offerings without stockholder approval.

         5.    PARTICIPATION.

               (a)  An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of EXHIBIT A to this Plan and filing it on or prior to the applicable Enrollment
Date with the Company's payroll office or such other office as the Company may
direct.

               (b)  Payroll deductions for a participant shall commence on the
first payroll following the Enrollment Date and shall end on the last payroll in
the Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

                                      -3-





         6.    PAYROLL DEDUCTIONS.

               (a)  At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding ten percent (10%) of the
Compensation which he or she receives on each pay day during the Offering
Period. Such payroll deductions shall be in whole percentages only.

               (b)  All payroll deductions made for a participant shall be
credited to his or her account under the Plan. A participant may not make any
additional payments into such account.

               (c)  A participant may discontinue his or her participation in
the Plan as provided in Section 10 hereof, or may increase or decrease the rate
of his or her payroll deductions during the Offering Period by completing and
filing with the Company a new subscription agreement authorizing a change in
payroll deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in payroll
deduction rate shall be effective with the first full payroll period following
ten (10) business days after the Company's receipt of the new subscription
agreement. A participant's subscription agreement shall remain in effect for
successive Offering Periods unless terminated as provided in Section 10 hereof.

               (d)  At the time the option is exercised, in whole or in part, or
at the time any of the Company's Common Stock issued under the Plan is disposed
of, the participant must make adequate provision for the Company's federal,
state, or other tax withholding obligations, if any, which arise upon the
exercise of the option or the disposition of the Common Stock. At any time, the
Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

         7.    GRANT OF OPTION. On the Enrollment Date of each Offering Period,
each eligible Employee participating in such Offering Period shall be granted an
option to purchase (at the applicable Purchase Price) up to a whole number of
shares of the Company's Common Stock the ("Option Shares") determined by
dividing $50,000 by the Fair Market Value of a share of Common Stock on the
Enrollment Date (subject to any adjustment pursuant to Section 18), and provided
that such purchase shall be subject to the limitations set forth in Sections
3(b) and 12 hereof. The option shall be exercisable as to 25% of the Option
Shares on each Exercise Date during the Offering Period. Exercise of the option
shall occur as provided in Section 8 hereof, unless the participant has
withdrawn pursuant to Section 10 hereof. The option shall expire on the last day
of the Offering Period.

         8.    EXERCISE OF OPTION. Unless a participant withdraws from the Plan
as provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on each Exercise Date during the Offering
Period, and a number of full shares not exceeding the number of shares as to
which such participant's option is exercisable on such Exercise Date shall be
purchased for such participant at the applicable Purchase Price with the
accumulated payroll

                                      -4-





deductions in his or her account. No fractional shares shall
be purchased. Any payroll deductions accumulated in a participant's account
which are not sufficient to purchase a full share of Common Stock shall be
retained in the participant's account for the subsequent Purchase Period or
Offering Period, subject to earlier withdrawal by the participant as provided in
Section 10 hereof. Any other monies left over in a participant's account after
the Exercise Date shall be returned to the participant. During a participant's
lifetime, a participant's option to purchase shares hereunder is exercisable
only by him or her.

         9.    DELIVERY. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant or to his or her designee, as appropriate, of a certificate
representing the shares purchased upon exercise of his or her option. The
Company may, in its sole discretion and in compliance with applicable laws,
authorize the use of book entry registration of shares in lieu of issuing
certificates.

         10.   WITHDRAWAL; TERMINATION OF EMPLOYMENT.

               (a)  A participant may withdraw all but not less than all the
payroll deductions credited to his or her account and not yet used to exercise
his or her option under the Plan at any time by giving written notice to the
Company in the form of EXHIBIT B to this Plan. All of the participant's payroll
deductions credited to his or her account shall be paid to such participant
promptly after receipt of notice of withdrawal and such participant's option for
the Offering Period shall be automatically terminated, and no further payroll
deductions for the purchase of shares shall be made for such Offering Period. If
a participant withdraws from an Offering Period, payroll deductions shall not
resume at the beginning of the succeeding Offering Period unless the participant
delivers to the Company a new subscription agreement.

               (b)  Upon a participant's ceasing to be an Employee (as defined
in Section 2(g) hereof), for any reason, he or she shall be deemed to have
elected to withdraw from the Plan and the payroll deductions credited to such
participant's account during the Offering Period but not yet used to exercise
the option shall be returned to such participant or, in the case of his or her
death, to the person or persons entitled thereto under Section 14 hereof, and
such participant's option shall be automatically terminated. If, prior to the
last day of the Offering Period, the Designated Subsidiary by which the Employee
is employed shall cease to be a Subsidiary of the Company, or if the Employee is
transferred to a Subsidiary of the Company that is not a Designated Subsidiary,
the Employee shall be deemed to have terminated employment for purposes of this
Plan.

               (c)  A participant's withdrawal from an Offering Period shall not
have any effect upon his or her eligibility to participate in any similar plan
which may hereafter be adopted by the Company or in succeeding Offering Periods.

                                      -5-





         11.   INTEREST. No interest shall accrue on the payroll deductions of a
participant in the Plan.

         12.   STOCK.

               (a)  The maximum number of shares of the Company's Common Stock
which shall be made available for sale under the Plan shall be 700,000 shares,
subject to adjustment as provided in Section 18(a) hereof. If, on a given
Exercise Date, the number of shares with respect to which options are to be
exercised exceeds the number of shares then available under the Plan, the
Company shall make a pro rata allocation of the shares remaining available for
purchase in as uniform a manner as shall be practicable and as it shall
determine to be equitable.

               (b)  The participant shall have no interest or voting right in
shares covered by his option until such option has been exercised.

               (c)  Shares to be delivered to a participant under the Plan shall
be registered in the name of the participant or in the name of the participant
and his or her spouse.

         13.   ADMINISTRATION. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

         14.   DESIGNATION OF BENEFICIARY.

               (a)  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 an Exercise Date on which the option is exercised but prior to
delivery to such participant 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 exercise of the option. If a participant is married and the
designated beneficiary is not the spouse, spousal consent shall be required for
such designation to be effective.

               (b)  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 and in the absence of a beneficiary validly designated under the
Plan 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.

                                      -6-





         15.   TRANSFERABILITY. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 14 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

         16.   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.

         17.   REPORTS. Individual accounts shall be maintained for each
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

         18.   ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION,
               LIQUIDATION, MERGER OR ASSET SALE.

               (a)  CHANGES IN CAPITALIZATION. The maximum number of shares of
Common Stock available for sale under the Plan, the Reserves, the maximum number
of shares each participant may purchase during each Purchase Period (pursuant to
Section 7), as well as the Purchase Price per share and the number of shares of
Common Stock covered by each option under the Plan which has not yet been
exercised, shall be proportionately adjusted for any increase or decrease in the
number of issued shares of Common Stock resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of shares of Common Stock
effected without receipt of consideration by the Company; provided, however,
that conversion of any convertible securities of the Company shall not be deemed
to have been "effected without receipt of consideration". Such adjustment shall
be made by the Board, whose determination in that respect shall be final,
binding and conclusive. Except as expressly provided herein, no issuance by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common Stock subject
to an option granted hereunder.

               (b)  DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, the Offering Periods shall terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

               (c)  REORGANIZATION EVENTS.

                    (1)  DEFINITION. A "Reorganization Event" shall mean: (a)
any merger or consolidation of the Company with or into another entity as a
result of which the Common Stock

                                      -7-





is converted into or exchanged for the right to receive cash, securities or
other property, (b) any exchange of shares of the Company for cash, securities
or other property pursuant to a share exchange transaction, or (c) any sale of
all or substantially all of the assets of the Company, each while unexercised
options remain outstanding under the Plan.

                    (2)  CONSEQUENCES OF A REORGANIZATION EVENT ON OPTIONS. Upon
the occurrence of a Reorganization Event, or the execution by the Company of any
agreement with respect to a Reorganization Event, the Board shall provide that
all outstanding options shall be assumed, or equivalent options shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof). For purposes hereof, an option shall be considered to be assumed if,
following consummation of the Reorganization Event, the option confers the right
to purchase, for each share of Common Stock subject to the option immediately
prior to the consummation of the Reorganization Event, the consideration
(whether cash, securities or other property) received as a result of the
Reorganization Event by holders of Common Stock for each share of Common Stock
held immediately prior to the consummation of the Reorganization Event (and if
holders were offered a choice of consideration, the type of consideration chosen
by the holders of a majority of the outstanding shares of Common Stock);
provided, however, that if the consideration received as a result of the
Reorganization Event is not solely common stock of the acquiring or succeeding
corporation (or an affiliate thereof), the Company may, with the consent of the
acquiring or succeeding corporation, provide for the consideration to be
received upon the exercise of options to consist solely of common stock of the
acquiring or succeeding corporation (or an affiliate thereof) equivalent in fair
market value to the per share consideration received by holders of outstanding
shares of Common Stock as a result of the Reorganization Event.

         Notwithstanding the foregoing, in the event that the acquiring or
succeeding corporation refuses to assume, or substitute for, the options, any
Offering Periods then in progress shall be shortened by setting a new Exercise
Date (the "New Exercise Date"), determined by the Board. The New Exercise Date
shall be before the date of the proposed Reorganization Event. The Board shall
notify each participant in writing at least ten (10) business days prior to the
New Exercise Date that the Exercise Date for the participant's option has been
changed to the New Exercise Date and that the participant's option shall be
exercised automatically on the New Exercise Date, unless prior to such date the
participant has withdrawn from the Offering Period as provided in Section 10
hereof.

         19.   AMENDMENT OR TERMINATION.

               (a)  The Board of Directors of the Company may at any time and
for any reason terminate or amend the Plan. Except as provided in Section 18
hereof, no such termination can affect options previously granted, provided that
an Offering Period may be terminated by the Board on any Exercise Date if the
Board determines that the termination of the Plan is in the best interests of
the Company and its stockholders. Except as provided in Section 18 hereof, no
amendment may make any change in any option theretofore granted which adversely
affects the rights of any participant. To the extent necessary to comply with
Section 423 of the Code (or any successor rule or provision or any other
applicable law or regulation), the Company shall obtain stockholder approval in
such a manner and to such a degree as required.

                                      -8-





               (b)  Without stockholder consent and without regard to whether
any participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation and establish such other limitations or procedures as
the Board (or its committee) determines in its sole discretion advisable which
are consistent with the Plan.

         20.   NOTICES. All notices or other communications by a participant to
the Company under or in connection with the Plan shall be deemed to have been
duly given when received in the form specified by the Company at the location,
or by the person, designated by the Company for the receipt thereof.

         21.   CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued
with respect to an option unless the exercise of such option and the issuance
and delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

               As a condition to the exercise of an option, the Company may
require the person exercising such option to represent and warrant at the time
of any such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

         22.   TERM OF PLAN. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 19 hereof.

         23.   AUTOMATIC TRANSFER TO LOW PRICE OFFERING PERIOD. To the extent
permitted by any applicable laws, regulations, or rules of the established stock
exchange, national market system, or over-the-counter market on which the Common
Stock trades, if the Fair Market Value of the Common Stock on the Enrollment
Date of the next Offering Period is lower than the Fair Market Value of the
Common Stock on the Enrollment Date of the current Offering Period, then all
participants in the current Offering Period shall be automatically withdrawn
from such Offering Period immediately after the exercise of their option on the
Exercise Date and shall be automatically re-enrolled in the next Offering Period
as of the first day thereof.

                                      -9-





         24.   GOVERNMENTAL REGULATIONS. The Company's obligation to sell and
deliver Common Stock under this Plan is subject to listing on an established
stock exchange or quotation on a national market system or an over the counter
market (to the extent the Common Stock is then so listed or quoted) and the
approval of all governmental authorities required in connection with the
authorization, issuance, or sale of such stock.

         25.   GOVERNING LAW. The Plan shall be governed by Delaware law except
to the extent that such law is preempted by federal law.

         26.   SOURCE OF SHARES. Shares may be issued upon exercise of an option
from authorized but unissued Common Stock, from shares held in the treasury of
the Company, or from any other proper source.

         27.   NOTIFICATION UPON SALE OF SHARES. Each employee agrees, by
participating in the Plan, to promptly give notice to the Company of any
disposition of shares purchased under the Plan where such disposition occurs
within two years after the date of the grant of the option pursuant to which
such shares were purchased or within one year of the date of exercise of such
option pursuant to which such shares were purchased.

                                      -10-
