arising under this Plan or any option granted hereunder, shall be final,
conclusive and binding upon all persons, including without limitation the

Common Stock, par value $0.01 of the Company ("Common Shares"), and they
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.
Appropriate adjustments in the number of shares and in the purchase price per
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
through a merger, consolidation, recapitalization, reclassification,

        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.

<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:
President. Except as otherwise provided in this Agreement, any such notice to
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.

              THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR
              INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
              ACT OF 1933, AS AMENDED. SUCH SECURITIES MAY NOT BE TRANSFERRED
              UNLESS A REGISTRATION STATEMENT UNDER SAID ACT IS IN EFFECT AS
              TO SUCH TRANSFER OR, IN THE OPINION OF COUNSEL SATISFACTORY TO
              THE ISSUER, SUCH TRANSFER MAY BE MADE WITHOUT REGISTRATION
              UNDER SAID ACT

Each Holder consents to Parent making a notation on its records and giving
instructions to any transfer agent of its capital stock in order to implement
the restrictions on transfer established in this Agreement and the Purchase
Agreement.

         4.   NOTICE OF PROPOSED TRANSFERS. The holder of each certificate
representing Restricted Securities by acceptance thereof agrees to comply in
all respects with the provisions of this Section 4. Without in any way
limiting the immediately preceding sentence or the provisions of Section 2,
no sale, assignment, transfer or pledge (other than (i) a sale made pursuant
to a registration statement filed under the Securities Act and declared
effective by the Commission or (ii) a sale made in accordance with the
applicable provisions of Rule 144) of Restricted Securities shall be made by
any holder thereof to any person unless such person shall first agree in
writing to be bound by the restrictions of this Agreement, including without
limitation this Section 4. Prior to any proposed sale, assignment, transfer
or pledge of any Restricted Securities, unless there is in effect a
registration statement under the Securities Act covering the proposed
transfer, the holder thereof shall give written notice to Parent of such
holder's intention to effect such transfer, sale, assignment or pledge. Each
such notice shall describe the manner and circumstances of the proposed
transfer, sale, assignment or pledge in sufficient detail, and, if requested
by Parent, the holder shall also provide, at such holder's expense, a written
opinion of legal counsel (who shall be, and whose legal opinion shall be,
reasonably satisfactory to Parent) addressed to Parent, to the effect that
the proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act and under applicable state securities
laws and regulations. Upon delivery to Parent of such notice and, if
required, such opinion, the holder of such Restricted Securities shall be
entitled to transfer such Restricted Securities in accordance with the terms
of such notice. Parent agrees that it shall not request such an opinion of
counsel with respect to (i) a transfer not involving a change in beneficial
ownership, (ii) a transaction involving the transfer without consideration of
Restricted Securities by an individual holder during such holder's lifetime
by way of gift or on death by will or the laws of descent and distribution.
Each certificate evidencing the Restricted Securities transferred

                                       -3-

<PAGE>

as above provided shall bear, except if such transfer is made pursuant to
Rule 144, the appropriate restrictive legend set forth in Section 3 above,
except that such certificate shall not bear such restrictive legend if, in
the opinion of counsel for such holder and counsel for Parent, such legend is
not required in order to establish or ensure compliance with any provision of
the Securities Act.

         5.   REGISTRATION ON FORM S-3.

              (a)  REGISTRATION. Parent shall use its commercially reasonable
efforts to cause a registration statement on Form S-3 (or any successor form,
a "FORM S-3") covering all Registrable Securities to be filed no later than
May 15, 2000, and declared effective as soon as practicable thereafter
provided that such date does not occur within any Black-Out Period and
provided further that the financial statements contained in Parent's most
recent quarterly or annual report on Form 10-Q and Form 10-K, respectively,
are not of a date 135 days or more on or prior to the 90th day following the
Closing Date, in which case, Parent shall use its commercially reasonable
efforts to cause such registration statement to be filed within ten (10) days
after Parent's next quarterly or annual report on Form 10-Q or Form 10-K, as
the case may be, is filed and declared effective as soon as practicable
thereafter. Parent shall use its commercially reasonable efforts to keep such
registration statement effective until the first anniversary of the date of
this Agreement, or such earlier date upon which no Holder holds any
Registrable Securities. Upon receipt of a notice from any Holder that such
Holder intends to sell Registrable Securities during a Permitted Window,
Parent shall, prior to the commencement of the Permitted Window, inform the
other Holders of the commencement of the Permitted Window. Parent shall
notify each of the Holders of the termination of a Permitted Window no later
than the time Parent notifies its executive officers and directors of the
corresponding Black-Out Period; PROVIDED, HOWEVER, that Parent need not
notify the Holders of regularly scheduled Black-Out Periods relating to the
closing of Parent's fiscal quarters, which periods commence on the fifteenth
day prior to the end of the last month of each fiscal quarter and terminate
twenty-four hours after Parent publicly announces its results for such
quarters.

              (b)  LIMITATIONS ON REGISTRATION AND SALE OF REGISTRABLE
SECURITIES. Notwithstanding anything in this Agreement to the contrary,
Parent's obligations and the Holders' rights under this Section 5 are subject
to the limitations and qualifications set forth below, which may be waived in
writing by Parent.

                   (i) Parent shall have no obligation to keep effective a
registration statement hereunder following such time as each Holder is
eligible to sell all of its Registrable Securities in a three month period
under the applicable provisions of Rule 144.

                   (ii) The Holders will sell Registrable Securities pursuant
to a registration effected hereunder only during a Permitted Window.

                   (iii) If Parent furnishes to the Holders a certificate
signed by the President or Chief Financial Officer of Parent stating that, in
the good faith judgment of the Board of Directors of Parent, it would be
seriously detrimental to Parent for a Form S-3 registration to be effected,
or a Permitted Window to be in effect, due to (A) the existence of a material
development or potential material development involving Parent which Parent
would be obligated to disclose in the

                                       -4-

<PAGE>

prospectus contained in the Form S-3 registration statement, which disclosure
would in the good faith judgment of the Board of Directors be premature or
otherwise inadvisable or (B) the existence of other facts or circumstances as
a result of which the prospectus contained or to be contained in the Form S-3
registration statement includes or would include an untrue statement of a
material fact or omits or would omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances under which they were made or then existing,
Parent may defer the filing of the Form S-3 registration statement or delay
the commencement of a Permitted Window or may effect an early termination of
a Permitted Window that has commenced, as the case may be. Parent may elect
to so defer, delay or terminate under clause (A) above only to the extent
that the event described in clause (A) also gives rise to a Black-Out Period
applicable to all of Parent's executive officers and directors under Parent's
Insider Trading Policy. If Parent elects to so defer, delay or terminate
under clause (B) above, Parent shall use its commercially reasonable efforts
to amend the registration statement or take such other action as may be
necessary to eliminate the situation described in clause (B) as soon as
practicable. Any Holder receiving any notice from Parent with respect to the
matters covered by this Section 5(b)(iii) shall keep the fact and content of
such notice, and the event or circumstances giving rise to such notice,
confidential.

                   (iv) The obligations of Parent hereunder are conditioned
upon its being eligible to register its securities on Form S-3 at the time
any such registration is otherwise required hereunder; provided, however that
Parent shall use its reasonable best efforts to remain eligible for use of
Form S-3 for the one-year period following the Effective Date; and provided
further that if after registration is accomplished on Form S-3 and prior to
the time that is one year following the Effective Date Parent is no longer
eligible to use Form S-3, subject to the provisions of this Section 5(b),
Parent shall undertake to continue the registration of the Registrable
Securities on another eligible form.

                   (v) Notwithstanding anything to the contrary in this
Agreement, Parent shall have no obligation to effect a registration
hereunder, and no Permitted Window will exist, with respect to Registrable
Securities that are subject to the escrow provisions of the Merger Agreement
(including any agreement which is an exhibit thereto) during the time that
such Registrable Securities are subject to such provisions and no Holder
shall sell any such Registrable Securities pursuant to a registration
hereunder, or pursuant to Rule 144, during any such period.

              (c)  REGISTRATION PROCEDURES. In connection with any
registration required under this Agreement, Parent shall take the actions set
forth below.

                   (i) Prior to filing any registration statement,
prospectus, amendment or supplement with the Commission in connection with
any registration hereunder, Parent shall furnish to one counsel selected by
the Holders of a majority of the Registrable Securities copies of such
documents.

                   (ii) Parent shall notify each Holder of any stop order
issued or threatened by the Commission and will take all reasonable actions
required to prevent the entry of such stop order or to remove it if entered.

                                       -5-

<PAGE>

                   (iii) Parent shall comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by a
registration statement filed pursuant to this Agreement with respect to the
disposition of all Registrable Securities covered by such registration
statement in accordance with the intended methods of disposition by the
Holders as set forth in such registration statement.

                   (iv) Parent shall furnish to each Holder and each
underwriter, if any, of Registrable Securities covered by a registration
statement filed pursuant to this Agreement such number of copies of such
registration statement, each amendment and supplement thereto (in each case
including all exhibits thereto), and the prospectus included in such
registration statement (including each preliminary prospectus), in conformity
with the requirements of the Securities Act, and such other documents as a
selling Holder may reasonably request in order to facilitate the disposition
of the Registrable Securities owned by such Holder. Such delivery of
documents shall be made by Parent within two (2) trading days of receipt of a
request therefor from a Holder.

                   (v) Parent shall use its best efforts to register or
qualify the Registrable Securities under the securities or "blue sky" laws of
each State of the United States of America as any of the Holders or
underwriters, if any, of the Registrable Securities covered by a registration
statement filed hereunder reasonably requests, and shall do any and all other
acts and things which may be reasonably necessary or advisable to enable each
selling Holder and each underwriter, if any, to consummate the disposition in
such States of the Registrable Securities owned by such selling Holders;
PROVIDED that Parent shall not be required to (A) qualify generally to do
business in any jurisdiction where it would not otherwise be required to
qualify but for this subsection (v), (B) subject itself to taxation in any
such jurisdiction or (C) consent to general service of process in any such
jurisdiction.

                   (vi) Parent shall immediately notify each Holder entitled
to sell Registrable Securities during a Permitted Window of the happening of
any event which comes to Parent's attention if, as a result of such event,
the prospectus included in the registration statement filed under this
Agreement contains any untrue statement of a material fact or omits to state
any material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, and Parent shall
promptly prepare and furnish to each Holder and file with the Commission a
supplement or amendment to such prospectus so that such prospectus will no
longer contain any untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

                   (vii) Parent shall take all such other reasonable and
customary actions as each Holder or the underwriters, if any, may reasonably
request in order to expedite or facilitate the disposition of the Registrable
Securities in accordance with the terms of this Agreement.

                   (viii) Parent shall make available for inspection by the
Holders, any underwriter participating in any disposition pursuant to a
registration statement filed under this Agreement, and any attorney,
accountant or other agent retained by such Holders or underwriters, all
financial and other records, pertinent corporate documents and properties of
Parent and its subsidiaries, as such person may reasonably request for the
purpose of confirming that such

                                       -6-

<PAGE>

registration statement does not contain any untrue statement of a material
fact or omit to state any material fact necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, provided that Parent obtains reasonably satisfactory assurances
that such information will be used solely for such purpose and will be held
in confidence (except to the extent that it is included in the registration
statement). Parent shall cause the officers, directors and employees of
Parent and each of its subsidiaries to supply such information and respond to
such inquiries as any Holder or underwriter may reasonably request or make
for the purpose of confirming that such registration statement does not
contain any untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading, provided that Parent obtains
reasonably satisfactory assurances that such information will be used solely
for such purpose and will be held in confidence (except to the extent that it
is included in the registration statement).

         6.   OTHER REGISTRATION RIGHTS. The Holders acknowledge that certain
other stockholders of Parent may now or hereafter have registration rights,
and that such other stockholders may be entitled to sell their securities at
the same time, or pursuant to the same registration and underwriting, as the
Holders hereunder.

         7.   EXPENSES OF REGISTRATION. All Registration Expenses incurred in
connection with Parent's obligations hereunder shall be borne by Parent. All
Selling Expenses relating to securities proposed to be registered hereunder
and all other registration expenses shall be borne by the Holders of such
securities pro rata on the basis of the number of shares proposed to be sold
by each of them during the applicable Permitted Window; provided, however,
that Parent shall be obligated to pay up to an aggregate of $3,000 for the
legal fees relating to securities proposed to be registered hereunder and all
other registration expenses of the Holders of such securities pro rata on a
basis of the number of shares proposed to be sold by each of them.

         8.   INDEMNIFICATION.

              (a) Parent will indemnify each Holder, each of its officers and
directors and partners, and each person controlling such Holder within the
meaning of Section 15 of the Securities Act, with respect to which
registration has been effected pursuant to this Agreement, against all
expenses, claims, losses, damages or liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other document, or
any amendment or supplement thereto, incident to any such registration, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading and Parent
will reimburse each such Holder, each of its officers, directors and
partners, and each person controlling such Holder, for any legal and any
other expenses reasonably incurred in connection with investigating,
preparing or defending any such claim, loss, damage, liability or action,
PROVIDED that Parent will not be liable in any such case to the extent that
any such claim, loss, damage, liability or expense arises out of or is based
on any untrue statement or omission or alleged untrue statement or omission,
made in reliance upon and

                                       -7-

<PAGE>

in conformity with written information furnished to Parent by an instrument
duly executed by such Holder or controlling person, and stated to be
specifically for use therein; and PROVIDED, FURTHER, that the foregoing
indemnity agreement is subject to the condition that, insofar as it relates
to any such untrue statement, alleged untrue statement, omission or alleged
omission made in a preliminary prospectus, such indemnity agreement shall not
inure to the benefit of any person, if a copy of the final prospectus or an
amended or supplemented prospectus, as applicable, was not furnished to the
person asserting the loss, liability, claim or damage at or prior to the time
such action is required by the Securities Act, and if the final prospectus or
the amended or supplemented prospectus, as applicable, would have cured the
defect giving rise to the loss, liability, claim or damage. In no event,
however, shall Parent have any indemnification obligation to the extent that
the expenses, claims, losses, damages or liabilities as to which
indemnification is sought are in connection with an offer or sale made by a
person other than Parent in violation of the terms of this Agreement (a
"VIOLATION").

              (b) Each Holder will, severally and not jointly and severally,
if Registrable Securities held by such Holder are included in the securities
as to which a registration hereunder is effected, indemnify Parent, each of
its directors and officers, each person who controls Parent within the
meaning of Section 15 of the Securities Act, and each other such Holder, each
of its officers and directors and each person controlling such Holder within
the meaning of Section 15 of the Securities Act, against all claims, losses,
damages and liabilities (or actions in respect thereof) arising out of or
based on (i) a Violation by such Holder or (ii) any untrue statement (or
alleged untrue statement) of a material fact contained in any such
registration statement, prospectus, offering circular or other document, or
any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements therein not
misleading, and will reimburse Parent, such Holders, such directors, officers
or control persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, but, in the case of clause (ii) above, only to the
extent that such untrue statement (or alleged untrue statement) or omission
(or alleged omission) is made in such registration statement, prospectus,
offering circular or other document in reliance upon and in conformity with
information furnished to Parent by such Holder. Notwithstanding the
foregoing, the liability of each Holder under this subsection 8.7(b) shall be
limited in an amount equal to the initial public offering price of the shares
sold by such Holder, unless such liability arises out of or is based on a
Violation or willful misconduct by such Holder.

              (c) Each party entitled to indemnification under this Section 8
(the "INDEMNIFIED PARTY") shall give notice to the party required to provide
indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified
Party has actual knowledge of any claim as to which indemnity may be sought,
and shall permit the Indemnifying Party to assume the defense of any such
claim or any litigation resulting therefrom, provided that (i) counsel for
the Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be approved by the Indemnified Party (whose approval shall
not unreasonably be withheld), and the Indemnified Party may participate in
such defense at such party's expense, (ii) that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under Section 8 of this Agreement
unless the failure to give such notice is materially prejudicial to an
Indemnifying Party's

                                       -8-

<PAGE>

ability to defend such action, and then only to the extent that such
Indemnifying Party is materially prejudiced, and (iii) that the Indemnifying
Party shall not assume the defense for matters as to which there is a
conflict of interest or there are separate and different defenses. No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party (whose consent shall not be
unreasonably withheld), consent to entry of any judgment or enter into any
settlement which (i) does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release
from all liability in respect to such claim or litigation or (ii) includes
admission of fault by the Indemnified Party. Notwithstanding the foregoing,
the liability of each Holder under this subsection 8.7(c) shall be limited in
an amount equal to the initial public offering price of the shares sold by
such Holder, unless such liability arises out of or is based on a Violation
or willful misconduct by such Holder.

         9.   INFORMATION BY HOLDER. The Holder or Holders of Registrable
Securities included in any registration hereunder shall furnish to Parent
such information regarding such Holder or Holders, the Registrable Securities
held by them and the distribution proposed by such Holder or Holders as
Parent may request in writing and as shall be required in connection with any
registration referred to in this Agreement.

         10.  RULE 144 REPORTING. With a view to making available the
benefits of certain rules and regulations of the Commission which may permit
the sale of the Restricted Securities to the public without registration
Parent agrees to use all reasonable efforts, at any time after the first
anniversary of the Effective Date, to:

              (a) Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act; and

              (b) File with the Commission in a timely manner all reports and
other documents required of Parent under the Securities Act and the Exchange
Act.

         11.  TRANSFER OF REGISTRATION RIGHTS. The rights to cause Parent to
register securities granted to Holders under Section 5 may be assigned to a
transferee or assignee reasonably acceptable to Parent in connection with any
transfer or assignment of Registrable Securities by the Holder, provided that
(i) such transfer is otherwise effected in accordance with applicable
securities laws and the terms of this Agreement, (ii) such assignee or
transferee acquires at least 10,000 shares of Registrable Securities (as
adjusted for stock splits, stock dividends, stock combinations and the like),
(iii) written notice is promptly given to Parent and (iv) such transferee
agrees in writing to be bound by the provisions of this Agreement.
Notwithstanding the foregoing, the rights to cause Parent to register
securities may be assigned without compliance with item (ii) above to a
family member or trust for the benefit of a Holder who is an individual, or a
trust for the benefit of a family member of such a Holder. In addition, a
distribution of Shares issued in the Merger without additional consideration
to underlying beneficial owners in proportion to the beneficial ownership
interests (such as the general and limited partners, Stockholders and trust
beneficiaries of a Holder) shall not be deemed to be an "assignment" or
"transfer" for purposes of the Section 11 and such underlying beneficial
owners shall be entitled to the same rights and subject to the same
restrictions under this Agreement as the initial Holder from which the
Registrable Securities were received

                                       -9-

<PAGE>

without any additional action on the part of any party to this Agreement
other than reasonable notice to Parent of such distribution.

         12.  AMENDMENT. Except as otherwise provided above, any provision of
this Agreement may be amended or the observance thereof may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of Parent and Holders of a
majority of the Registrable Securities remaining at the time such amendment
or waiver is made.

         13.  GOVERNING LAW. This Agreement shall be governed in all respects
by the laws of the State of California, without regard to conflict of laws
provisions.

         14.  ENTIRE AGREEMENT. This Agreement constitutes the full and
entire understanding and Agreement among the parties regarding the matters
set forth herein. Except as otherwise expressly provided herein, all other
agreements regarding the registration rights of the Company's Stockholders
shall hereby expire. The provisions hereof shall inure to the benefit of, and
be binding upon the successors, permitted assigns, heirs, executors and
administrators of the parties hereto.

         15.  NOTICES. All notices and other communications required or
permitted hereunder shall be in writing and shall be mailed by registered or
certified mail, postage prepaid, or otherwise delivered by facsimile
transmission, by hand or by messenger, addressed:
