the intention of the Company to have the Plan qualify as an "Employee Stock 
Purchase Plan" under Section 423 of the Internal Revenue Code of 1986, as 
amended.  The provisions of the Plan, accordingly, shall be construed so as 
to extend and limit participation in a manner consistent with the 
requirements of that section of the Code.

Exchange Commission for the initial public offering of the Common Stock; or

               (4)  In the absence of an established market for the Common 
Stock, the Fair Market Value thereof shall be determined in good faith by the

participate in the Plan.

          (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

would own capital stock of the Company and/or hold outstanding options to 
purchase such stock representing five percent (5%) or more of the total 
combined voting power or value of all classes of the capital stock of the 
Company or of any Subsidiary, or (ii) to the extent that his or her rights to 
purchase stock under all employee stock purchase plans of the Company and its

($25,000) worth of stock (determined at the fair market value of the shares 
at the time such option is granted) for each calendar year in which such 
option is outstanding at any time.

     4.   OFFERING PERIODS.  Generally, the Plan shall be implemented by 
consecutive, overlapping Offering Periods with a new Offering Period

Offering Periods (including the commencement dates thereof) with respect to 
future offerings without shareholder approval if such change is announced at

Period to be affected thereafter.

     5.   PARTICIPATION.

          (a)  An eligible Employee may become a participant in the Plan by 
completing a subscription agreement provided by the Company authorizing 
payroll deductions and filing it with the Company's payroll office prior to 
the applicable Enrollment Date.

          (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. 

     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 fifteen percent 
(15%) of the Compensation which he or she receives on each pay day during the 
Offering Period. 

          (b)  All payroll deductions made for a participant shall be 
credited to his or her account under the Plan and shall be withheld in whole 
percentages only.  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 decrease the rate of his or her 
payroll deductions one time during a Purchase Period by completing or filing 
with the Company a new subscription agreement authorizing a change in payroll 
deduction rate.  In addition, a participant may increase or decrease his or 
her deduction rate upon the commencement of a Purchase Period.  The change in 
rate shall be effective with the first full payroll period following five (5) 
business days after the Company's receipt of the new subscription agreement 
unless the Company elects to process a given change in participation more 
quickly.  A participant's subscription agreement shall remain in effect for 
successive Offering Periods unless terminated as provided in Section 10 
hereof.

                                - 4 -


          (d)  Notwithstanding the foregoing, a participant's payroll 
deductions may be decreased to zero percent (0%) at any time during an 
Purchase Period to the extent necessary to comply with Section 423(b)(8) of 
the Code and Section 3(b) hereof. Payroll deductions shall recommence at the 
rate provided in such participant's subscription agreement at the beginning 
of the first Purchase Period during which an employee's participation shall 
so comply, unless terminated by the participant as provided in Section 10 
hereof.

          (e)  At the time the option is exercised, in whole or in part, or 
at the time some or all 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 on each Exercise Date during such Offering Period (at 
the applicable Purchase Price) up to a number of shares of the Company's 
Common Stock determined by dividing such Employee's payroll deductions 
accumulated prior to such Exercise Date and retained in the Participant's 
account as of the Exercise Date by the applicable Purchase Price.  During a 
six-month Purchase Period an Employee shall in no event be permitted to 
purchase more than the lesser of 2,000 shares or such number of shares as may 
be determined by the Plan administrator; provided, however, that such limit 
shall be adjusted proportionately in the case of a Purchase Period longer 
than six months.  The number of shares that may be purchased shall also be 
subject to the limitations set forth in Sections 3(b) and 12 hereof.  
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 the Exercise Date, and the maximum 
number of full shares subject to option shall be purchased for such 
participant at the applicable Purchase Price with the accumulated payroll 
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 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.

                                - 5 -


     9.   DELIVERY.  As promptly as practicable after each Exercise Date, the 
shares purchased upon exercise of an option shall be credited to an account 
in the participant's name with a brokerage firm selected by the Company to 
hold the shares in its street name. 

     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 completing a notice 
of withdrawal provided by the Company and filing it with the Company's 
payroll office.  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. 

          (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 which commence after the termination of the Offering Period from 
which the participant withdraws.

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

     12.  STOCK.

          (a)  Subject to Section 18, the maximum number of shares of the 
Company's Common Stock which shall be made available for sale under the Plan 
shall be 1,200,000 shares, plus an annual increase to be added on November 1 
of each year equal to the lesser of (i) 2.0 percent of the Shares of Common 
Stock outstanding on the last day of each preceding fiscal year, (ii) 
3,000,000 Shares or (iii) a lesser amount determined by the Board.  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 

                                - 6 -


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.

          (a)  ADMINISTRATIVE BODY.  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.

     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 

                                - 7 -


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.  Subject to any required action by 
the shareholders of the Company, the Reserves, as well as the 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.

          (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)  MERGER OR ASSET SALE.  In the event of a proposed sale of all 
or substantially all of the assets of the Company, or the merger of the 
Company with or into another corporation, any Purchase Periods then in 
progress shall be shortened by setting a new Exercise Date (the "New Exercise 
Date") and any Offering Periods then in progress shall end on the New 
Exercise Date.  The New Exercise Date shall be before the date of the 
Company's proposed sale or merger.  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

                                - 8 -


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 of Directors on any 
Exercise Date if the Board determines that the termination of the Plan is in 
the best interests of the Company and its shareholders.  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 under Section 423 of the Code (or any 
successor rule or provision or any other applicable law, regulation or stock 
exchange rule), the Company shall obtain shareholder approval in such a 
manner and to such a degree as required.

          (b)  Without shareholder 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.

                                - 9 -


          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 
shareholders 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 stock exchange rules, if the 
Fair Market Value of the Common Stock on any Exercise Date in an Offering 
Period is lower than the Fair Market Value of the Common Stock on the 
Enrollment Date of such Offering Period, then all participants in such 
Offering Period shall be automatically withdrawn from such Offering Period 
immediately after the exercise of their option on such Exercise Date and 
automatically re-enrolled in the immediately following Offering Period as of 
the first day thereof.
