shall not exceed 10,000 in the aggregate; provided, however, if any option
lapses or terminates for any reason before such option has been completely
exercised, the Common Shares covered by the unexercised portion of such
option may again be made subject to options granted under this Plan.

share-may be made by the Committee in its sole discretion to give effect to
adjustments made in the number of outstanding Common Shares of the Company

        5. TERMS AND CONDITIONS OF OPTIONS.

        (a) Subject to the terms and conditions of this Plan, the Committee
may, from time to time, grant to such persons as the Committee may determine
options to purchase such number of Common Shares of the Company on such terms
and conditions as the Committee may determine. In determining the persons to
whom options shall be granted and the number of Common Shares to be covered
by each option, the Committee may take into account the nature of the
employment of or association with such persons, their present and potential
contributions to the success of the Company, and such other factors as the
Committee in its sole discretion shall deem relevant. The date and time of
approval by the Committee of the granting of an option shall be considered
the date and the time of the grant of such option.

        (b) The purchase price of each Common Share subject to an option
granted pursuant to this Plan shall be fixed by the Committee.

        (c) In connection with - the grant of an option pursuant to this
Plan, the Committee may specify the date when such option shall become
exercisable; provided that if the Committee does not specify such a date,
then the option shall be immediately exercisable.

        (d) Each option granted pursuant to this Plan and all rights to
purchase shares thereunder shall cease on the earliest of:

            (i) ten years after the date such option is granted or on such
date prior thereto as may be fixed by the Committee on or before the date
such option is granted; or

            (ii) the date, if any, fixed for cancellation pursuant to Section
8 of this Plan.

In no event shall any option be exercisable at any time after its original
expiration date. When an option is no longer exercisable, it shall be deemed
to have lapsed or terminated and will no longer be outstanding.

        6. MANNER OF EXERCISING OPTIONS. A person entitled to exercise an
option granted under this Plan may, subject to its terms and conditions and
the terms and conditions of this Plan, exercise it, in whole at any time, or
in part from time to time, by delivery to the Company at its principal
executive office, to the attention of its President, of written notice of
exercise, specifying the number of shares with respect to which the option is
being exercised, accompanied by payment in full of the purchase price of the
shares to be purchased at the time. No shares shall be issued until full
payment therefor has been made. The granting of an option to an individual
shall give such individual no rights as a stockholder except as to shares
issued to such individual.

        7. TRANSFERABILITY AND TERMINATION OF OPTIONS. During the lifetime of
an optionee, only such optionee or his or her guardian or legal
representative may exercise options granted under this Plan. An option may be
exercised within one year after the death of the optionee by such
individual's legal representatives, heirs or legatees, but only to the extent

                                      -2-
<PAGE>

that the option was exercisable, in whole or in part, immediately prior to
such individual's death. No option granted under this Plan shall be
assignable or transferable by the optionee otherwise than by will or the laws
of descent and distribution.

        8. MERGER, CONSOLIDATION, DISSOLUTION OR LIQUIDATION. In the event of
(a) a proposed merger or consolidation of the Company with or into any other
corporation, regardless of whether the Company is the surviving corporation
(unless appropriate provision shall have been made for the protection of the
outstanding options granted under this Plan by the substitution, in lieu of
such options, of options to Purchase appropriate voting common stock (the
"Survivor's Stock") of the corporation surviving any such merger or
consolidation or, if appropriate, the parent corporation of the Company or
such surviving corporation, or, alternatively, by the delivery of a number of
shares of the Survivor's Stock which has a fair market value, as determined
in good faith by the Committee, as of the effective date of such merger or
consolidation equal to the product of (i) the excess of (x) the Event
Proceeds per Common Share (as hereinafter defined) covered by the option as
of such effective date, over (y) the option price per Common Share,
multiplied by (ii) the number of Common Shares covered by such option), or
(b) the, proposed dissolution or liquidation of the Company (such merger,
consolidation, dissolution or liquidation being herein called an "Event"),
then the Committee shall declare, at least ten days prior to the actual
effective date of an Event, and provide written notice to each optionee of
the declaration, that each outstanding option, whether or not then
exercisable, shall be cancelled at the time of, or immediately prior to the
occurrence of, the Event (unless it shall have been exercised prior to the
occurrence of the Event) in exchange for payment to each optionee, within ten
days after the Event, of cash equal to the amount (if any), for each Common
Share covered by the cancelled option, by which the Event Proceeds per Common
Share exceeds the exercise price per Common Share covered by such option. At
the time of such declaration, each option shall immediately become
exercisable in full and each optionee shall have the right, during the period
preceding the time of cancellation of the option, to exercise his or her
option as to all or any part of the Common Shares covered thereby. Each
outstanding option granted pursuant to this Plan that shall not have been
exercised prior to the Event shall be cancelled at the time of, or
immediately prior to, the Event, as provided in the declaration, and this
Plan shall terminate at the time of such cancellation, subject to the payment
obligations of the Company provided in this Section 8. For purposes of this
Section, "Event Proceeds per Common Share" shall mean the cash plus the fair
market value, as determined in good faith by the Committee, of the non-cash
consideration to be received per Common Share by the stockholders of the
Company upon the occurrence of the Event.

        9. TAX WITHHOLDING. Delivery of Common Shares upon exercise of any
stock option granted under this Plan shall be subject to any required
withholding taxes. A person exercising such an option may, as a condition
precedent to receiving the Common Shares, be required to pay the Company a
cash amount equal to the amount of any required withholdings.

        10. OTHER TERMS AND CONDITIONS. The Committee shall have the power,
subject to the terms and conditions contained herein, to fix any other terms
and conditions for the grant or exercise of any option under this Plan.
Nothing contained in this Plan, or in any

                                      -3-
<PAGE>

option granted pursuant to this Plan, shall confer upon any employee holding
an option any right to continued employment by the Company or any subsidiary
of the Company or limit in any way the right of the Company or any such
subsidiary to terminate an employee's employment at any time.

        11. OPTION AGREEMENTS. All options granted under this Plan shall be
evidenced by a written agreement in such form or forms as the Committee may
from time to time determine. The Committee may condition the granting of
options to a person hereunder upon the execution by such person of an
agreement regarding the transferability of Common Shares in form and
substance reasonably satisfactory to the Company.

        12. AMENDMENT AND DISCONTINUANCE OF PLAN. The Board may at any time
amend, suspend or discontinue this Plan; provided, however, that no amendment
to this Plan shall, without the consent of the holder of the option, alter or
impair any options previously granted under this Plan.

        13. EFFECTIVE DATE. This Plan shall be effective as of August 29,
1994.

        STOCK OPTION AGREEMENT dated as ____________________ between Wild
File, Inc., a Delaware corporation (the "Company"), and the optionee (the
"Optionee") listed above.

        WHEREAS, the Company desires to carry out the purposes of the Wild
File, Inc. 1994 Stock Option Plan (the "Plan") by affording the Optionee an
opportunity to purchase Common Stock, par value $0.01 per share, of the
Company ("Common Shares") according to the terms set forth herein.

        NOW, THEREFORE, the parties hereto hereby agree as follows:

        1. GRANT OF OPTION. Subject to the terms of the Plan, the Company
hereby grants to the Optionee the right and option (the "Option") to purchase
the number of Common Shares specified in the schedule at the beginning of
this Agreement, on the terms and conditions hereinafter set forth. The Option
is not intended by the Company to be an "incentive stock option" within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code").

        2. PURCHASE PRICE. The purchase price of each of the Common Shares
subject to the Option shall be the exercise price per share specified in the
schedule at the beginning of this Agreement, which price has been specified
in accordance with the Plan.

<PAGE>

        3. OPTION PERIOD.

        (a) Subject to the provisions of Section 5 hereof, the Option shall
be exercisable, in whole or in part, as to the number of shares specified in
the schedule at the beginning of this Agreement at any time on or prior to
the expiration date specified in such schedule. Notwithstanding the foregoing
or any other provision herein to the contrary, the Option shall become
immediately exercisable in the event that the committee under the Plan (the
"Committee") shall declare pursuant to Section 8 of the Plan that the Option
shall be cancelled at the time of, or immediately prior to the occurrence of
an Event, as therein defined.

        (b) The Option and all rights to purchase shares thereunder shall
cease on the earliest of:

            (i)  the expiration date specified in the schedule at the
        beginning of this Agreement (which date shall not be more than ten
        years after the date of this Agreement); or

            (ii) the date, if any, fixed for cancellation pursuant to
        Section 8 of the Plan.

Notwithstanding any other provision in this Agreement, in no event may anyone
exercise the Option, in whole or in part, after its original expiration date.

        4.       MANNER OF EXERCISING OPTION.

        (a) Subject to the terms and conditions of this Agreement, the Option
may be exercised by delivering written notice of exercise to the Company at
its principal executive office, to the attention of the President. The notice
shall state the election to exercise the Option and the number of Common
Shares in respect of which it is being exercised, and shall be signed by the
person exercising the Option. If the person exercising the Option is not the
Optionee, he or she also shall send with the notice appropriate proof of his
or her right to exercise the Option. Such notice shall be accompanied by
payment in cash of the full purchase price of the Common Shares being
purchased.

        (b) As soon as practicable after receipt of the purchase price
provided for above, the Company shall deliver to the person exercising the
Option, in the name of the Optionee or his or her estate or heirs, as the
case may be, a certificate or certificates representing the Common Shares
being purchased. The Company shall pay all original issue or transfer taxes,
if any, with respect to the issue or transfer of the Common Shares to the
person exercising the Option and all fees and expenses necessarily incurred
by the Company in connection therewith. All Common Shares so issued shall be
fully paid and nonassessable. Notwithstanding anything to the contrary in
this Agreement, the Company shall not be required, upon the exercise of this
Option or any part thereof, to issue or deliver any Common Shares prior to
the completion of any registration or other qualification of such Common
Shares required by applicable federal and state securities laws.

                                      -2-
<PAGE>

        5. ACCELERATION AND CANCELLATION OF OPTION IN CERTAIN EVENTS. As
provided in Section 8 of the Plan, in certain events the Committee shall
declare by prior written notice to the Optionee that the Option, whether or
not then exercisable, shall be cancelled at the time of, or immediately
prior to the occurrence of the Event, as defined in Section 8 of the Plan, in
exchange for certain payments to the Optionee. At the time of any such
declaration, the Option shall become immediately exercisable. The Option, to
the extent not exercised prior to the Event, shall be cancelled at the time
of, or immediately prior to, the Event in accordance with the declaration.

        6. LIMITATION ON TRANSFER. During the lifetime of the Optionee, only
the Optionee or his or her guardian or legal representative may exercise the
Option. In the event of the Optionee's death, the legal representative, heirs
or legatees of the Optionee's estate or the person who acquired the right to
exercise the Option by bequest or inheritance may exercise the Option within
one year after the death of the Optionee but only to the extent that the
Option was exercisable, in whole or in part, immediately prior to the
Optionee's death. The Optionee shall not assign or transfer the Option
otherwise than by will or the laws of descent and distribution, and the
Option shall not be subject to pledge, hypothecation, execution, attachment
or similar process. Any attempt to assign, transfer, pledge, hypothecate or
otherwise dispose of the Option contrary to the provisions hereof, and the
levy of any attachment or similar process upon the Option, shall be null and
void.

        7. STOCKHOLDER RIGHTS BEFORE EXERCISE. The Optionee shall have none
of the rights of a stockholder of the Company with respect to any share
subject to the Option until the share is actually issued to him or her upon
exercise of the Option.

        8. DISCRETIONARY ADJUSTMENT. The Committee may in its sole discretion
make appropriate adjustments in the number of shares subject to the Option
and in the purchase price per share to give effect to any adjustments made in
the number of outstanding Common Shares of the Company through a merger,
consolidation, recapitalization, reclassification, combination, stock
dividend, stock split or other relevant change, provided that fractional
shares shall be rounded to the nearest whole share.

        9. TAX WITHHOLDING. The parties hereto recognize that the Company or
a subsidiary thereof may be obligated to withhold federal and state income
taxes and social security or other taxes upon the Optionee's exercise of the
Option. The Optionee agrees that, at the time he or she exercises the Option,
if the Company or subsidiary thereof is required to withhold such taxes, he
or she will promptly pay in cash upon demand to the Company, or the
subsidiary having such obligation, such amounts as shall be necessary to
satisfy such obligation.

        10. RIGHT OF FIRST REFUSAL.

        (a) The Optionee agrees not to sell, exchange or otherwise transfer
for value, or pledge or otherwise encumber, all or any part of the Common
Shares issued pursuant to this Agreement, or any shares of capital stock of
the Company from time to time issued in respect thereof, whether as a stock
dividend, pursuant to a stock split or otherwise (such Common Shares,

                                      -3-
<PAGE>

together with such shares of capital stock of the Company issued in respect
thereof, hereinafter collectively called the "Restricted Shares") unless the
Optionee first offers the Restricted Shares he or she intends to transfer or
encumber to the Company on the terms and conditions hereinafter contained.
Any such offer shall be made in writing and shall contain the name and
address of each person to or in favor of whom the Optionee intends to
transfer or encumber all or any pall of the Restricted Shares and shall
specify the terms and conditions of the intended transfer or encumbrance,
including without limitation, the proposed consideration. The Company may,
prior to the purchase of any Restricted Shares hereunder, require evidence
of a bona fide intention to transfer or encumber the Restricted Shares.

        (b) All offers under Section 10(a) hereof shall specify the notice
address of the offeror for acceptance of such offer. If the Optionee shall
fail to extend an offer required by Section 10(a) hereof, then for purposes
of this Agreement the Optionee shall be deemed to have extended an offer on
such date, if any, as the Company gives written notice to the person stating
that such person has failed to extend an offer and that such notice from the
Company shall be deemed to constitute such offer for purposes of this
Agreement.

        (c) After receipt of an offer under Section 10(a) hereof, the Company
shall have the right for a period of sixty (60) days to elect to purchase, at
the price specified in this Section 10, all or any part of the Restricted
Shares offered to the Company by mailing written notice of such election
within such period to the offeror at the address specified in the offer (or,
if the offer fails to specify a notice address, at the address to which
notice to the Optionee is given pursuant to Section 14 hereof).

        (d) In the event that the Company does not exercise a right granted
to it pursuant to Section 10(a) hereof, the Optionee may transfer or encumber
the Restricted Shares which were subject to such right without regard to
Section 10(a) hereof, but only (i) during a period of thirty (30) days
following the 60-day period specified in Section 10(c) hereof, (ii) solely to
the persons or entities listed in the offer to the Company, and (iii) at a
price and upon terms not less advantageous to the Optionee than the price and
terms stated in the offer to the Company. If the transfer or encumbrance of
the Restricted Shares is not consummated within such 30-day period, such
Restricted Shares shall again be the subject to all requirements of Section
10 hereof, including without limitation Section 10(a).

        (e) In the event of any transfer of all or any part of the Restricted
Shares., the transferee shall agree in writing to take the Restricted Shares
subject to the provisions of this Section 10 and the related provisions of
this Agreement giving effect thereto.

        (f) Except as otherwise provided in this Section 10(f), the purchase
price for Restricted Shares purchased pursuant to this Section 10 shall be
the appraised value of the Restricted Shares determined pursuant to Section
12 hereof. In the case of a fight granted pursuant to Section 10(a) hereof
where the Optionee proposes to transfer the Restricted Shares to a third
party for consideration expressed in monetary terms or having a readily
ascertainable market value, then the purchase price at which the Company has
the right to purchase such

                                      -4-
<PAGE>

Restricted Shares shall be an amount equal to the value of the consideration
for which the Optionee proposes to transfer the Restricted shares to a third
party.

        11. PAYMENT FOR REPURCHASE OF SHARES. In order to effect a repurchase
of Restricted Shares pursuant to Section 10 hereof, within ten (10) days of
the later of (i) the date on which the right is exercised, or (ii) the date
on which the Company receives the report of the Appraiser setting forth the
appraised value of the Restricted Shares, the seller shall tender to the
Company the Restricted Shares to be purchased and the Company shall
simultaneously pay the purchase price therefor in cash.

        12. APPRAISAL OF SHARES. Whenever it will be necessary to determine
the appraised value of Restricted Shares for purposes of this Agreement, the
Board of Directors of the Company shall select an investment baking firm or
other entity expert in the valuation of closely-held companies (the
"Appraiser"), who shall be engaged at the expense of the Company, to value
the Restricted Shares based upon a going-concern value without discount for
any minority interest. The appraised value of the Restricted Shares shall be
as of a date not more than six (6) months prior to the date on which the
option to repurchase the Restricted Shares is exercised.

        13. EXPIRATION UPON PUBLIC MARKET. The rights granted pursuant to
Section 10 hereof shall expire at such time as there has been sold to the
general public in an underwritten offering or offerings pursuant to one or
more registration statements filed with, and declared effective by, the
Securities and Exchange Commission under the Securities Act of 1933, as
amended, an aggregate number of Shares equal to at least twenty-five percent
of the Shares outstanding after the last such sale.

        14. NOTICE. Every notice to be given pursuant to the provisions of
this Agreement shall be in writing and delivered by hand or sent by certified
mail, return receipt requested. Any such notice to the Company shall be
addressed to 17020 12th Avenue North, Plymouth, Minnesota 55447, Attention:

the Optionee shall be the address set forth following the signature of the
Optionee. Either party may change its address by notice to the other party in
accordance with this Section 14.

        15. LEGEND ON STOCK CERTIFICATES. In addition to such legends as the
Company employs to evidence that the Restricted Shares have not been
registered under any federal or state securities laws, all Restricted Shares
shall contain the following legend:

        The shares evidenced by this certificate and any transfer
        thereof are subject to the terms of the Option Agreement
        between __________________ and the Company dated as of
        ________________ a copy of which is on file at the registered
        office of the Company.

        16. INTERPRETATION OF THIS AGREEMENT. All decisions and
interpretations made by the Committee with regard to any question arising
hereunder or under the Plan shall be binding and conclusive upon the Company
and the Optionee. In the event that there is any

                                      -5-
<PAGE>

inconsistency between the provisions of this Agreement arid the Plan, the
provisions of the Plan shall govern.

        17. DISCONTINUANCE OF EMPLOYMENT OR ASSOCIATION This Agreement shall
not give the Optionee a right to continued employment or association with the
Company or any subsidiary thereof, and the Company or any subsidiary thereof
employing the Optionee or with whom the Optionee is associated may terminate
his or her employment or association and otherwise deal with the Optionee
without regard to the effect it may have upon him or her under this
Agreement.

        18. GENERAL. The Company shall at all times during the term of this
Option reserve and keep available such number of Common Shares as win be
sufficient to satisfy the requirements of this Option Agreement. This
Agreement shall be binding in all respects on the Optionee's heirs,
representatives, successors and assigns. This Agreement is entered into under
the laws of the State of Minnesota and shall be construed and interpreted
thereunder.

        IN WITNESS WHEREOF, the Optionee and the Company have executed this
Agreement as of the day and year first above written.
