                           County of Hennepin, State of Minnesota (the "Land").

         3. Amendment of Section 2. Acceptance of Premises. Section 2 of the
Lease is hereby amended by adding the following:

         Tenant has personally inspected the Second Additional Space and accepts
         the same "as is" without representation or warranty by Landlord of any
         kind and with the understanding that Landlord shall have no
         responsibility with respect thereto except to construct in a good and
         workmanlike manner the improvements designated as Landlord's
         obligations as per mutually agreed upon plans and specifications and
         which shall be attached hereto as Second Amended Exhibit E. Tenant has
         personally inspected the Leased Premises and accepts the same "AS-IS"
         without representation or warranty by Landlord of any kind and with the
         understanding that Landlord shall have no responsibility with respect
         thereto, except Landlord shall provide an allowance for the direct
         costs of tenant finish improvements to the Leased Premises in an amount
         up to Nine Thousand Dollars ($9,000.00) (the "Allowance") to be used by
         Tenant prior to the Commencement Date. The Allowance shall be used
         exclusively to construct and pay for the tenant finish improvements set
         forth in Exhibit B (the "TFI"), that are directly related to the
         construction of the Leased Premises. Tenant shall reimburse Landlord
         for any cost or expense attributable to the tenant finish improvements
         which exceed the Allowance no later than thirty (30) days after receipt
         of an invoice from Landlord for such costs or expenses. Any Allowance
         not used by Tenant prior to the Commencement Date shall be forfeited by
         Tenant. Such tenant

<PAGE>   2

         finish improvement work shall be performed at Tenant's sole cost and
         expense and in accordance with plans and specifications prepared at
         Tenant's sole cost, which shall be reasonably agreed upon by both
         Landlord and Tenant upon prior to the commencement of the TFI. Tenant
         shall perform the TFI work in a good and workmanlike manner, in
         accordance with all applicable laws, regulations and building codes and
         Landlord's approvals which shall not be unreasonably withheld or
         delayed. The parties agree that it shall not be unreasonable for
         Landlord to withhold approval if, in Landlord's reasonable opinion, the
         proposed TFI plans and specifications do not match the existing
         architectural design and style of the Building or the proposed
         materials are not of equal or greater quality than existing Building
         standard. Landlord shall have the right to approve Tenant's contractor
         and all subcontractors performing such work, taking into consideration
         the quality of work and timeliness of performance. Tenant shall pay
         Landlord a fee for its supervision of the project, including review and
         approval of space plans and construction documents, equal to three
         percent (3%) of the total project cost. Within two business days of
         Tenant's receipt thereof, Tenant shall forward all invoices for TFI
         from contractors and subcontractors for the TFI to Landlord for payment
         from the Allowance and Landlord shall promptly process such invoices
         for payment until the amount of the Allowance is exhausted. Thereafter
         the payment of such bills and charges shall be Tenant's sole liability.
         The Tenant shall provide Landlord with copies of as-built plans and
         specifications upon completion of the TFI. No person shall be entitled
         to any lien derived through or under Tenant for any labor or material
         furnished to the Leased Premises, and nothing in this Lease shall be
         construed to constitute a consent by Landlord to the creation of any
         lien. If any lien is filed against the Leased Premises for work claimed
         to have been done for or material claimed to have been furnished to
         Tenant, Tenant shall cause such lien to be discharged of record within
         thirty (30) days after filing. Tenant shall indemnify Landlord from all
         costs, losses, expenses and attorneys' fees in connection with any
         construction or alteration and any related lien. Tenant agrees that all
         work on the initial and any subsequent tenant finish improvements shall
         be performed by Duke Construction Limited Partnership or a subsidiary
         or affiliate of Landlord ("Duke") which shall receive a construction
         management fee as Landlord's construction manager or general
         contractor.

         Provided Tenant is not in default, effective January 1, 2002 and every
         six (6) months thereafter, Tenant shall have the right to terminate
         this Lease by providing Landlord with six (6) months' prior written
         notice and as a condition of Tenant's termination, paying to Landlord
         as a termination fee in available bank funds, the sum of the following
         items (i) one month's gross rent based on monthly billing at the time
         notice is given; plus (ii) the unamortized portion of the leasing
         commissions in the amount of Thirty-six Thousand Five Hundred

         to United Properties Corporation in connection with the Lease; plus
         (iii) the unamortized portion of the leasing commissions in connection
         with the First Lease Amendment in the amount of Two Thousand Five
         Hundred Forty-nine Dollars and Seventy-three Cents ($2,549.73); plus
         (iv) the unamortized cost of the tenant finish improvements in the
         amount of Five Thousand Dollars ($5,000.00) (without consideration of
         any salvage value) made by Landlord pursuant to the Lease; (v) the
         unamortized cost of the tenant finish improvements of in the amount of
         Seven Thousand Two Hundred Forty-eight Dollars ($7,248.00) for the
         Additional Space; and (vi) the unamortized cost of the tenant finish
         improvements in the amount of Thirteen Thousand Three Hundred Six and
         00/100 Dollars ($13,306.00) as of the Termination Date. The
         amortization of the total costs as set forth above will be on a
         straight-line basis, using an eleven percent (11%) interest rate over
         the initial sixty (60) month term of the Lease with respect to subparts
         (ii) and (iv) and over the balance of the Lease Term remaining with
         respect to subparts (iii) and (v). See Amended Exhibit H for the
         amortization schedule.

         5. Tenant's Representations and Warranties. The undersigned represents
and warrants to Landlord that (i) Tenant is duly organized, validly existing and
in good standing in accordance with the laws of the state under which it was
organized; (ii) all action necessary to authorize the execution of this
Amendment has been taken by Tenant; and (iii) the individual executing and
delivering this Amendment on behalf of Tenant has been authorized to do so, and

and it is not effective until execution by and delivery to both Landlord and
Tenant.

four (4) consecutive purchase periods of six (6) months' duration. The last day
of each Purchase Period shall be the "Purchase Date" for such Purchase Period. A
Purchase Period commencing on May 1 shall end on the next October 31. A Purchase
Period commencing on November 1 shall end on the next April 30. The first
Offering Period shall have three Purchase Periods. The first Purchase Period of
the first Offering Period shall commence on the IPO Date and shall end on April
30, 2001, with the second Purchase Period beginning on May 1, 2001 and ending on
October 31, 2001, and the third Purchase Period beginning on November 1, 2001
and ending on April 30, 2002. The Board of Directors of the Company shall have
the power to change the duration and/or frequency of Purchase Periods with
respect to future purchases without stockholder approval if such change is
announced at least five (5) days prior to the scheduled beginning of the first
Purchase Period to be affected.

     5.   Participation.

          (a) An eligible Employee may become a participant in the Plan by
completing a subscription agreement on the form provided by the Company and
filing it with the Company's Human Resources Department or the stock brokerage
or other financial services firm designated by the Company (the "Designated
Broker") prior to the applicable Offering Date, unless a later time for filing
the subscription agreement is set by the Board for all eligible Employees with
respect to a given Offering Period. The subscription agreement shall set forth
the percentage of the participant's Compensation (subject to Section 6(a) below)
to be paid as Contributions pursuant to the Plan.

          (b) Payroll deductions shall commence on the first full payroll
following the Offering Date and shall end on the last payroll paid on or prior
to the last Purchase Period of the Offering Period to which the subscription
agreement is applicable, unless sooner terminated by the participant as provided
in Section 10.

          (c) Participants are responsible for the payment of all income taxes,
employment, social insurance, welfare and other taxes under applicable law
relating to any amounts deemed under the laws of the country of their residency
or of the organization of the Subsidiary which employs them to constitute income
arising out of the Plan, the purchase and sale of Shares pursuant to the Plan
and the distribution of Shares or cash to the participant in accordance with the
Plan. Each participant, by participating in the Plan, authorizes the Company or
the relevant Subsidiary to make appropriate withholding deductions from each
participant's compensation, which shall be in addition to any payroll deductions
made pursuant

                                  Page 3 of 10

<PAGE>   4

to Section 6 below, and to pay such amounts to the appropriate tax authorities
in the relevant country or countries in order to satisfy any of the above tax
liabilities of the participant under applicable law.

     6.   Method of Payment of Contributions.

          (a) A participant shall elect to have payroll deductions made on each
payday during the Offering Period in an amount not less than one percent (1%)
and not more than ten percent (10%) (or such other percentage as the Board may
establish from time to time before an Offering Date) of such participant's
Compensation on each payday during the Offering Period. All payroll deductions
made by a participant shall be credited to his or her account under the Plan. A
participant may not make any additional payments into such account, except as
provided in Section 11.

          (b) A participant may discontinue his or her participation in the Plan
as provided in Section 10, or, unless otherwise provided by the Administrator,
on one occasion only during a Purchase Period may increase and on one occasion
only during a Purchase Period may decrease the rate of his or her Contributions
with respect to the ongoing Offering Period by completing and filing with the
Company a new subscription agreement authorizing a change in the payroll
deduction rate. The change in rate shall be effective as of the beginning of the
next pay period following the date of filing of the new subscription agreement,
if the agreement is filed at least ten (10) business days prior to such date
and, if not, as of the beginning of the next succeeding pay period.

          (c) Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) herein, a participant's
payroll deductions may be decreased during any Offering Period scheduled to end
during the current calendar year to 0%. Payroll deductions shall re-commence at
the rate provided in such participant's subscription agreement at the beginning
of the first Offering Period that is scheduled to end in the following calendar
year, unless terminated by the participant as provided in Section 10.

     7.   Grant of Option.

          (a) On the Offering Date of each Offering Period, each eligible
Employee participating in such Offering Period shall be granted an option to
purchase on each Purchase Date a number of Shares of the Company's Common Stock
determined by dividing such Employee's Contributions accumulated prior to such
Purchase Date and retained in the participant's account as of the Purchase Date
by the applicable Purchase Price; provided however that the maximum number of
Shares an Employee may purchase during each Purchase Period shall be 2,000
Shares (subject to any adjustment pursuant to Section 19 below), and provided
further that such purchase shall be subject to the limitations set forth in
Sections 3(b) and 13 of this Plan and Section 423 of the Code.

          (b) The fair market value of the Company's Common Stock on a given
date (the "Fair Market Value") shall be determined by the Board in its
discretion based on the closing sales price of the Common Stock for such date
(or, in the event that the Common Stock is not traded on such date, on the
immediately preceding trading date), as reported by the National Association of
Securities Dealers Automated Quotation (Nasdaq) National Market or, if such
price is not reported, the mean of the bid and asked prices per share of the
Common Stock as reported by Nasdaq or, in the event the Common Stock is listed
on a stock exchange, the Fair Market Value per share shall be the closing sales
price on such exchange on such date (or, in the event that the Common Stock is
not traded on such date, on the immediately preceding trading date), as reported
in The Wall Street Journal. For purposes of the Offering Date under the first
Offering Period under the Plan, the Fair Market Value of a share of the Common
Stock of the Company shall be the Price to Public as set forth in the final
prospectus filed with the Securities and Exchange Commission pursuant to Rule
424 under the Securities Act of 1933, as amended.

                                  Page 4 of 10

<PAGE>   5

     8. Exercise of Option. Unless a participant withdraws from the Plan as
provided in Section 10, his or her option for the purchase of Shares will be
exercised automatically on each Purchase Date of an Offering Period, and the
maximum number of full Shares subject to the option will be purchased at the
applicable Purchase Price with the accumulated Contributions in his or her
account. No fractional Shares shall be issued. Any payroll deductions
accumulated in a participant's account that 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 below. Any other amounts left over in a
participant's account after a Purchase Date shall be returned to the
participant. The Shares purchased upon exercise of an option hereunder shall be
deemed to be transferred to the participant on the Purchase Date. During his or
her lifetime, a participant's option to purchase Shares hereunder is exercisable
only by him or her.

     9. Delivery. Within thirty (30) days after each Purchase Date of each
Offering Period, the number of Shares purchased by each participant upon
exercise of his or her option shall be deposited into an account established in
the participant's name with the Designated Broker.

     10.  Voluntary Withdrawal; Termination of Employment.

          (a) A participant may withdraw all but not less than all the
Contributions credited to his or her account under the Plan at any time prior to
each Purchase Date by giving written notice to the Company or the Designated
Broker, as directed by the Company. All of the participant's Contributions
credited to his or her account will be paid to him or her promptly after receipt
of his or her notice of withdrawal and his or her option for the current period
will be automatically terminated, and no further Contributions for the purchase
of Shares will be made during the Offering Period.

          (b) Upon termination of the participant's Continuous Status as an
Employee prior to the Purchase Date of an Offering Period for any reason,
including retirement or death, the Contributions credited to his or her account
will be returned to him or her or, in the case of his or her death, to the
person or persons entitled thereto under Section 14, and his or her option will
be automatically terminated.

          (c) In the event an Employee fails to remain in Continuous Status as
an Employee of the Company for at least twenty (20) hours per week during the
Offering Period in which the employee is a participant, he or she will be deemed
to have elected to withdraw from the Plan and the Contributions credited to his
or her account will be returned to him or her and his or her option terminated.

          (d) A participant's withdrawal from an offering will not have any
effect upon his or her eligibility to participate in a succeeding offering or in
any similar plan that may hereafter be adopted by the Company.

     11. Automatic Withdrawal. If the Fair Market Value of the Shares on any
Purchase Date of an Offering Period is less than the Fair Market Value of the
Shares on the Offering Date for such Offering Period, then every participant
shall automatically (i) be withdrawn from such Offering Period at the close of
such Purchase Date and after the acquisition of Shares for such Purchase Period,
and (ii) be enrolled in the Offering Period commencing on the first business day
subsequent to such Purchase Period. Participants shall automatically be
withdrawn as of October 31, 2000 from the Offering Period beginning on the IPO
Date and re-enrolled (with all Contributions carried forward) in the Offering
Period beginning on November 1, 2000 if the Fair Market Value of the Shares on
the IPO Date is greater than the Fair Market Value of the Shares on October 31,
2000, unless a participant notifies the Administrator prior to October 31, 2000
that he or she does not wish to be withdrawn and re-enrolled; and, in connection

                                  Page 5 of 10

<PAGE>   6

therewith, any new participant to the Offering Period beginning on November 1,
2000 may make an additional Contribution up to the maximum amount of any
Contribution carried forward by a participant.

     12.  Interest.  No interest shall accrue on the Contributions of a
participant in the Plan.

     13.  Stock.

          (a) Subject to adjustment as provided in Section 19, the maximum
number of Shares which shall be made available for sale under the Plan shall be
500,000 Shares, plus an automatic annual increase on the first day of each of
the Company's fiscal years beginning in 2002 and ending in 2010 equal to the
lesser of (i) 200,000 Shares, (ii) two percent (2%) of the Shares outstanding on
the last day of the immediately preceding fiscal year, or (iii) a lesser amount
determined by the Board. If the Board determines that, on a given Purchase Date,
the number of shares with respect to which options are to be exercised may
exceed (i) the number of shares of Common Stock that were available for sale
under the Plan on the Offering Date of the applicable Offering Period, or (ii)
the number of shares available for sale under the Plan on such Purchase Date,
the Board may in its sole discretion provide (x) that the Company shall make a
pro rata allocation of the Shares of Common Stock available for purchase on such
Offering Date or Purchase Date, as applicable, in as uniform a manner as shall
be practicable and as it shall determine in its sole discretion to be equitable
among all participants exercising options to purchase Common Stock on such
Purchase Date, and continue all Offering Periods then in effect, or (y) that the
Company shall make a pro rata allocation of the shares available for purchase on
such Offering Date or Purchase Date, as applicable, in as uniform a manner as
shall be practicable and as it shall determine in its sole discretion to be
equitable among all participants exercising options to purchase Common Stock on
such Purchase Date, and terminate any or all Offering Periods then in effect
pursuant to Section 20 below. The Company may make pro rata allocation of the
Shares available on the Offering Date of any applicable Offering Period pursuant
to the preceding sentence, notwithstanding any authorization of additional
Shares for issuance under the Plan by the Company's stockholders subsequent to
such Offering Date.

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

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

     14.  Administration.

         (a) The Board, or a committee named by the Board, shall supervise and
administer the Plan and shall have full power to adopt, amend and rescind any
rules deemed desirable and appropriate for the administration of the Plan and
not inconsistent with the Plan, to construe and interpret the Plan, and to make
all other determinations necessary or advisable for the administration of the
Plan.

         (b) The Board, or a committee named by the Board, shall, to the extent
necessary or desirable, establish any special rules for Employees, former
Employees or participants located in any particular country other than the
United States. Such rules shall be set forth in Appendices to the Plan, which
shall be deemed incorporated into and form part of the Plan.

     15.  Designation of Beneficiary.

          (a) A participant may designate 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 end of a

                                  Page 6 of 10

<PAGE>   7

Purchase Period but prior to delivery to him or her of such Shares and cash. In
addition, a participant may designate 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 Purchase Date of an Offering Period. If a participant is
married and the designated beneficiary is not the spouse, spousal consent shall
be required for such designation to be effective. Beneficiary designations under
this Section 15(a) shall be made as directed by the Company's Human Resources
Department.

          (b) Such designation of beneficiary may be changed by the participant
(and his or her spouse, if any) 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.

     16. Transferability. Neither Contributions 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 15) 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 in
accordance with Section 10.

     17.  Use of Funds.  All Contributions 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 Contributions.

     18. Reports. Individual accounts will be maintained for each participant in
the Plan. Statements of account will be provided to participating Employees by
the Company or the Designated Broker at least annually, which statements will
set forth the amounts of Contributions, the per Share Purchase Price, the number
of Shares purchased and the remaining cash balance, if any.

     19.  Adjustments Upon Changes in Capitalization; Corporate Transactions.

          (a) Adjustment. Subject to any required action by the stockholders of
the Company, the number of Shares covered by each option under the plan that has
not yet been exercised and the number of Shares that have been authorized for
issuance under the Plan but have not yet been placed under option (collectively,
the "Reserves"), as well as the maximum number of shares of Common Stock that
may be purchased by a participant in a Purchase Period, the number of shares of
Common Stock set forth in Section 13(a)(i) above, and the price per Share of
Common Stock covered by each option under the Plan that has not yet been
exercised, shall be proportionately adjusted for any increase or decrease in the
number of issued Shares resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock (including any
such change in the number of Shares of Common Stock effected in connection with
a change in domicile of the Company), or any other increase or decrease in the
number of Shares 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
issue by the Company of shares of stock of

                                  Page 7 of 10

<PAGE>   8

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 subject to an option.

          (b) Corporate Transactions. In the event of a dissolution or
liquidation of the Company, any Purchase Period and Offering Period then in
progress will terminate immediately prior to the consummation of such action,
unless otherwise provided by the Board. In the event of a Corporate Transaction,
each option outstanding under the Plan shall be assumed or an equivalent option
shall be substituted by the successor corporation or a parent or Subsidiary of
such successor corporation. In the event that the successor corporation refuses
to assume or substitute for outstanding options, each Purchase Period and
Offering Period then in progress shall be shortened and a new Purchase Date
shall be set (the "New Purchase Date"), as of which date any Purchase Period and
Offering Period then in progress will terminate. The New Purchase Date shall be
on or before the date of consummation of the transaction and the Board shall
notify each participant in writing, at least ten (10) days prior to the New
Purchase Date, that the Purchase Date for his or her option has been changed to
the New Purchase Date and that his or her option will be exercised automatically
on the New Purchase Date, unless prior to such date he or she has withdrawn from
the Offering Period as provided in Section 10. For purposes of this Section 19,
an option granted under the Plan shall be deemed to be assumed, without
limitation, if, at the time of issuance of the stock or other consideration upon
a Corporate Transaction, each holder of an option under the Plan would be
entitled to receive upon exercise of the option the same number and kind of
shares of stock or the same amount of property, cash or securities as such
holder would have been entitled to receive upon the occurrence of the
transaction if the holder had been, immediately prior to the transaction, the
holder of the number of Shares of Common Stock covered by the option at such
time (after giving effect to any adjustments in the number of Shares covered by
the option as provided for in this Section 19); provided however that if the
consideration received in the transaction is not solely common stock of the
successor corporation or its parent (as defined in Section 424(e) of the Code),
the Board may, with the consent of the successor corporation, provide for the
consideration to be received upon exercise of the option to be solely common
stock of the successor corporation or its parent equal in Fair Market Value to
the per Share consideration received by holders of Common Stock in the
transaction.

     The Board may, if it so determines in the exercise of its sole discretion,
also make provision for adjusting the Reserves, as well as the price per Share
of Common Stock covered by each outstanding option, in the event that the
Company effects one or more reorganizations, recapitalizations, rights offerings
or other increases or reductions of Shares of its outstanding Common Stock, and
in the event of the Company's being consolidated with or merged into any other
corporation.

     20.  Amendment or Termination.

          (a) The Board may at any time and for any reason terminate or amend
the Plan. Except as provided in Section 19, no such termination of the Plan may
affect options previously granted, provided that the Plan or an Offering Period
may be terminated by the Board on a Purchase Date or by the Board's setting a
new Purchase Date with respect to an Offering Period and Purchase Period then in
progress if the Board determines that termination of the Plan and/or the
Offering Period is in the best interests of the Company and the stockholders or
if continuation of the Plan and/or the Offering Period would cause the Company
to incur adverse accounting charges as a result of a change after the effective
date of the Plan in the generally accepted accounting rules applicable to the
Plan. Except as provided in Section 19 and in this Section 20, no amendment to
the Plan shall make any change in any option previously granted that adversely
affects the rights of any participant. In addition, to the extent necessary to
comply with Rule 16b-3 under the Exchange Act, or under Section 423 of the Code
(or any successor rule or provision or any applicable law or regulation), the
Company shall obtain stockholder approval in such a manner and to such a degree
as so required.

                                  Page 8 of 10

<PAGE>   9

          (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 and Purchase
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 that are consistent with the Plan.

     21. 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.

     22. 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 Exchange Act, the rules and regulations
promulgated thereunder, applicable state securities laws 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.

     23. Term of Plan; Effective Date. The Plan shall become effective upon the
IPO Date. If the Plan is not approved by the shareholders prior to April 30,
2001, all Contributions will be returned to each participant without interest
and the Plan will be terminated. The Plan shall continue in effect for a term of
ten (10) years unless sooner terminated under Section 20 or this Section 23.

     24. Additional Restrictions of Rule 16b-3. The terms and conditions of
options granted hereunder to, and the purchase of Shares by, persons subject to
Section 16 of the Exchange Act shall comply with the applicable provisions of
Rule 16b-3. This Plan shall be deemed to contain, and such options shall
contain, and the Shares issued upon exercise thereof shall be subject to, such
additional conditions and restrictions as may be required by Rule 16b-3 to
qualify for the maximum exemption from Section 16 of the Exchange Act with
respect to Plan transactions.

     25. Miscellaneous. Nothing in this Plan shall confer on any participant any
express or implied right of continued employment by the Company or any
Subsidiary, whether for the duration of the Plan or otherwise. Nothing in this
Plan shall confer on any person any legal or equitable right against the Company
or any of its affiliates, directly or indirectly, or give rise to any cause of
action at law or in equity against the Company or any of its affiliates. Neither
the Shares purchased hereunder nor any other benefits conferred hereby,
including the right to purchase Shares at a discount, shall form any part of the
wages or salary of any Employee for purposes of severance pay or termination
indemnities, irrespective of the reason for termination of employment. Under no
circumstances shall any person ceasing to be an employee of the Company or any
of its affiliates be entitled to any compensation for any loss or any right

                                  Page 9 of 10

<PAGE>   10

or benefit under this Plan which such employee might otherwise have enjoyed but
for termination of employment, whether such compensation is claimed by way of
damages for wrongful or unfair dismissal, breach of contract or otherwise.

     26. Acceptance of Terms. By participating in the Plan, each participant
shall be deemed to have accepted all the conditions of the Plan and the terms
and conditions of any rules and regulations adopted by the Board or its
committee administering the Plan and shall be fully bound thereby.
