3.       PLAN ADMINISTRATION.

         3.1 THE COMMITTEE. The Plan will be administered by the Board or by 
a committee of the Board. So long as the Company has a class of its equity 
securities registered under Section 12 of the Exchange Act, any committee 
administering the Plan will consist solely of two or more members of the 
Board who are "non-employee directors" within the meaning of Rule 16b-3 under 
the Exchange Act and, if the Board so determines in its sole discretion, who 
are "outside directors" within the meaning of Section 162(m) of the Code. 
Such a committee, if established, will act by majority approval of the 
members (unanimous approval with respect to action by written consent), and a 
majority of the members of such a committee will constitute a quorum. As used 
in the Plan, "Committee" will refer to the Board or to such a committee, if 
established. To the extent consistent with corporate law, the Committee may 
delegate to any officers of the Company the duties, power and authority of 
the Committee under the Plan pursuant to such conditions or limitations as 
the Committee may establish; provided, however, that only the Committee may 
exercise such duties, power and authority with respect to Eligible Recipients 
who are subject to Section 16 of the 

                                      3


Exchange Act. The Committee may exercise its duties, power and authority 
under the Plan in its sole and absolute discretion without the consent of any 
Participant or other party, unless the Plan specifically provides otherwise. 
Each determination, interpretation or other action made or taken by the 
Committee pursuant to the provisions of the Plan will be conclusive and 
binding for all purposes and on all persons, and no member of the Committee 
will be liable for any action or determination made in good faith with 
respect to the Plan or any Incentive Award granted under the Plan.

         3.2  AUTHORITY OF THE COMMITTEE.

              (a) In accordance with and subject to the provisions of the Plan,
         the Committee will have the authority to determine all provisions of
         Incentive Awards as the Committee may deem necessary or desirable and
         as consistent with the terms of the Plan, including, without
         limitation, the following: (i) the Eligible Recipients to be selected
         as Participants; (ii) the nature and extent of the Incentive Awards to
         be made to each Participant (including the number of shares of Common
         Stock to be subject to each Incentive Award, any exercise price, the
         manner in which Incentive Awards will vest or become exercisable and
         whether Incentive Awards will be granted in tandem with other Incentive
         Awards) and the form of written agreement, if any, evidencing such
         Incentive Award; (iii) the time or times when Incentive Awards will be
         granted; (iv) the duration of each Incentive Award; and (v) the
         restrictions and other conditions to which the payment or vesting of
         Incentive Awards may be subject. In addition, the Committee will have
         the authority under the Plan in its sole discretion to pay the economic
         value of any Incentive Award in the form of cash, Common Stock or any
         combination of both.

              (b) The Committee will have the authority under the Plan to amend
         or modify the terms of any outstanding Incentive Award in any manner,
         including, without limitation, the authority to modify the number of
         shares or other terms and conditions of an Incentive Award, extend the
         term of an Incentive Award, accelerate the exercisability or vesting or
         otherwise terminate any restrictions relating to an Incentive Award,
         accept the surrender of any outstanding Incentive Award or, to the
         extent not previously exercised or vested, authorize the grant of new
         Incentive Awards in substitution for surrendered Incentive Awards;
         provided, however that the amended or modified terms are permitted by
         the Plan as then in effect, that no amendment or modification of an
         outstanding Incentive Award (other than as may be required pursuant to
         Section 4.3 of the Plan) may decrease the per share exercise price of
         an Option below the Fair Market Value of the Common Stock on the date
         of grant, and that any Participant adversely affected by such amended
         or modified terms has consented to such amendment or modification.

              (c) In the event of (i) any reorganization, merger, consolidation,
         recapitalization, liquidation, reclassification, stock dividend, stock
         split, combination of shares, rights offering, extraordinary dividend
         or divestiture (including a spin-off) or any other change in corporate
         structure or shares, (ii) any purchase, acquisition, sale or
         disposition of a 

                                      4


         significant amount of assets or a significant business, (iii) any 
         change in accounting principles or practices, or (iv) any other similar
         change, in each case with respect to the Company or any other entity 
         whose performance is relevant to the grant or vesting of an Incentive 
         Award, the Committee (or, if the Company is not the surviving 
         corporation in any such transaction, the board of directors of the 
         surviving corporation) may, without the consent of any affected 
         Participant, amend or modify the vesting criteria of any outstanding 
         Incentive Award that is based in whole or in part on the financial 
         performance of the Company (or any Subsidiary or division or other 
         subunit thereof) or such other entity so as equitably to reflect such 
         event, with the desired result that the criteria for evaluating such 
         financial performance of the Company or such other entity will be 
         substantially the same (in the sole discretion of the Committee or the 
         board of directors of the surviving corporation) following such event 
         as prior to such event; provided, however, that the amended or modified
         terms are permitted by the Plan as then in effect.

4.       SHARES AVAILABLE FOR ISSUANCE.

         4.1 MAXIMUM NUMBER OF SHARES AVAILABLE. Subject to adjustment as 
provided in Section 4.3 of the Plan, the maximum number of shares of Common 
Stock that will be available for issuance under the Plan will be 12,000,000 
shares of Common Stock. Notwithstanding any other provisions of the Plan to 
the contrary, no Participant in the Plan may be granted any Options or any 
other Incentive Awards with a value based solely on an increase in the value 
of the Common Stock after the date of grant, relating to more than 2,500,000 
shares of Common Stock in the aggregate during any 48- month period (subject 
to adjustment as provided in Section 4.3 of the Plan). The shares available 
for issuance under the Plan may, at the election of the Committee, be either 
treasury shares or shares authorized but unissued, and, if treasury shares 
are used, all references in the Plan to the issuance of shares will, for 
corporate law purposes, be deemed to mean the transfer of shares from 
treasury.

         4.2 ACCOUNTING FOR INCENTIVE AWARDS. Shares of Common Stock that are 
issued under the Plan or that are subject to outstanding Incentive Awards 
will be applied to reduce the maximum number of shares of Common Stock 
remaining available for issuance under the Plan. Any shares of Common Stock 
that are subject to an Incentive Award that lapses, expires, is forfeited or 
for any reason is terminated unexercised or unvested and any shares of Common 
Stock that are subject to an Incentive Award that is settled or paid in cash 
or any form other than shares of Common Stock will automatically again become 
available for issuance under the Plan. Any shares of Common Stock that 
constitute the forfeited portion of a Restricted Stock Award, however, will 
not become available for further issuance under the Plan.

         4.3 ADJUSTMENTS TO SHARES AND INCENTIVE AWARDS. In the event of any 
reorganization, merger, consolidation, recapitalization, liquidation, 
reclassification, stock dividend, stock split, combination of shares, rights 
offering, divestiture or extraordinary dividend (including a spin-off) or any 
other change in the corporate structure or shares of the Company, the 
Committee (or, if the Company is not the surviving corporation in any such 
transaction, the board of directors of the 

                                      5


surviving corporation) will make appropriate adjustment (which determination 
will be conclusive) as to the number and kind of securities or other property 
(including cash) available for issuance or payment under the Plan and, in 
order to prevent dilution or enlargement of the rights of Participants, (a) 
the number and kind of securities or other property (including cash) subject 
to outstanding Incentive Awards, and (b) the exercise price of outstanding 
Options.

5.       PARTICIPATION.

         Participants in the Plan will be those Eligible Recipients who, in 
the judgment of the Committee, have contributed, are contributing or are 
expected to contribute to the achievement of economic objectives of the 
Company or its Subsidiaries. Eligible Recipients may be granted from time to 
time one or more Incentive Awards, singly or in combination or in tandem with 
other Incentive Awards, as may be determined by the Committee in its sole 
discretion. Incentive Awards will be deemed to be granted as of the date 
specified in the grant resolution of the Committee, which date will be the 
date of any related agreement with the Participant.

6.       OPTIONS.

         6.1 GRANT. An Eligible Recipient may be granted one or more Options 
under the Plan, and such Options will be subject to such terms and 
conditions, consistent with the other provisions of the Plan, as may be 
determined by the Committee in its sole discretion. The Committee may 
designate whether an Option is to be considered an Incentive Stock Option or 
a Non-Statutory Stock Option. To the extent that any Incentive Stock Option 
granted under the Plan ceases for any reason to qualify as an "incentive 
stock option" for purposes of Section 422 of the Code, such Incentive Stock 
Option will continue to be outstanding for purposes of the Plan but will 
thereafter be deemed to be a Non-Statutory Stock Option.

         6.2 EXERCISE PRICE. The per share price to be paid by a Participant 
upon exercise of an Option will be determined by the Committee in its 
discretion at the time of the Option grant, provided that such price will not 
be less than 100% of the Fair Market Value of one share of Common Stock on 
the date of grant.

         6.3 EXERCISABILITY AND DURATION. An Option will become exercisable 
at such times and in such installments and upon such terms and conditions as 
may be determined by the Committee in its sole discretion at the time of 
grant (including without limitation that (i) the Participant remain in the 
continuous employ or service of the Company or a Subsidiary for a certain 
period, (ii) the Participant comply with certain requirements, (iii) the 
Participant, the Company or any division or subunit thereof, satisfy certain 
performance goals or criteria or (iv) the Common Stock satisfy certain 
performance goals or criteria); provided, however, that no Option may be 
exercisable prior to six months (other than as provided in Section 9.1 of the 
Plan) or after 10 years from its date of grant.

         6.4 PAYMENT OF EXERCISE PRICE. The total purchase price of the 
shares to be purchased upon exercise of an Option will be paid entirely in 
cash (including check, bank draft or money order); 

                                      6


provided, however, that the Committee, in its sole discretion and upon terms 
and conditions established by the Committee, may allow such payments to be 
made, in whole or in part, by tender of a Broker Exercise Notice, by tender 
(through actual delivery or attestation) of Previously Acquired Shares or by 
a combination of such methods.

         6.5 MANNER OF EXERCISE. An Option may be exercised by a Participant 
in whole or in part from time to time, subject to the conditions contained in 
the Plan and in the agreement evidencing such Option, by delivery in person, 
by facsimile or electronic transmission or through the mail of written notice 
of exercise to the Company at its principal executive office in St. Paul, 
Minnesota and by paying in full the total exercise price for the shares of 
Common Stock to be purchased in accordance with Section 6.4 of the Plan.

7.       RESTRICTED STOCK AWARDS.

         7.1 GRANT. An Eligible Recipient may be granted one or more 
Restricted Stock Awards under the Plan, and such Restricted Stock Awards will 
be subject to such terms and conditions, consistent with the other provisions 
of the Plan, as may be determined by the Committee in its sole discretion. 
The Committee may impose such restrictions or conditions, not inconsistent 
with the provisions of the Plan, to the vesting of such Restricted Stock 
Awards as it deems appropriate, including, without limitation, that (i) the 
Participant remain in the continuous employ or service of the Company or a 
Subsidiary for a certain period; (ii) the Participant comply with certain 
requirements; (iii) the Participant or the Company (or any Subsidiary or 
division or other subunit thereof) satisfy certain performance goals or 
criteria; or (iv) the Common Stock satisfy certain performance goals or 
criteria, provided, however, that other than as provided in Section 9.1 of 
the Plan, no Restricted Stock Award may vest prior to six months from its 
date of grant.

         7.2 RIGHTS AS A STOCKHOLDER; TRANSFERABILITY. Except as provided in 
Sections 7.1, 7.3, 7.4 and 12.3 of the Plan, a Participant will have all 
voting, dividend, liquidation and other rights with respect to shares of 
Common Stock issued to the Participant as a Restricted Stock Award under this 
Section 7 upon the Participant becoming the holder of record of such shares 
as if such Participant were a holder of record of shares of unrestricted 
Common Stock.

         7.3 DIVIDENDS AND DISTRIBUTIONS. Unless the Committee determines 
otherwise in its sole discretion (either in the agreement evidencing the 
Restricted Stock Award at the time of grant or at any time after the grant of 
the Restricted Stock Award), any dividends or distributions (other than 
regular quarterly cash dividends) paid with respect to shares of Common Stock 
subject to the unvested portion of a Restricted Stock Award will be subject 
to the same restrictions as the shares to which such dividends or 
distributions relate. The Committee will determine in its sole discretion 
whether any interest will be paid on such dividends or distributions. The 
Committee, in an agreement evidencing a Restricted Stock Award, may require 
that, unless the Participant elects otherwise, regular quarterly cash 
dividends paid with respect to shares of Common Stock subject to a portion of 
the Restricted Stock Award that has not vested will be reinvested (and in 
such case 

                                      7


Participants hereby consent to such reinvestment) in shares of Common Stock 
pursuant and in accordance with the Company's regular dividend reinvestment 
plan.

         7.4 ENFORCEMENT OF RESTRICTIONS. To enforce the restrictions 
referred to in this Section 7, the Committee may place a legend on the stock 
certificates referring to such restrictions and may require the Participant, 
until the restrictions have lapsed, to keep the stock certificates, together 
with duly endorsed stock powers, in the custody of the Company or its 
transfer agent, or to maintain evidence of stock ownership, together with 
duly endorsed stock powers, in a certificateless book-entry stock account 
with the Company's transfer agent.

8.       PERFORMANCE STOCK AWARDS.

         An Eligible Recipient may be granted one or more Performance Stock 
Awards under the Plan, and such Performance Stock Awards will be subject to 
such terms and conditions, if any, consistent with the other provisions of 
the Plan, as may be determined by the Committee in its sole discretion. The 
Participant will have all voting, dividend, liquidation and other rights with 
respect to the shares of Common Stock issued to a Participant as a 
Performance Stock Award under this Section 8 upon the Participant becoming 
the holder of record of such shares; provided, however, that the Committee 
may impose such restrictions on the assignment or transfer of a Performance 
Stock Award as it deems appropriate, and may enforce such restrictions by any 
or all of the methods set forth in Section 7.4 of the Plan.

9.       EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER SERVICE.

         9.1 TERMINATION OF EMPLOYMENT DUE TO DEATH OR DISABILITY. In the 
event a Participant's employment with the Company and all Subsidiaries is 
terminated by reason of death or Disability:

              (a) All outstanding Options then held by the Participant will
         become immediately exercisable in full and will remain exercisable for
         a period of five years after such termination (but in no event after
         the expiration date of any such Option);

              (b) All Restricted Stock Awards then held by the Participant will
         become fully vested; and

              (c) Any assignment or transfer restrictions with respect to
         Performance Stock Awards will lapse.

         9.2 TERMINATION OF EMPLOYMENT DUE TO RETIREMENT. Subject to Section 
9.6 of the Plan, in the event a Participant's employment with the Company and 
all Subsidiaries is terminated by reason of Retirement:

              (a) All outstanding Options then held by the Participant will, to
         the extent exercisable as of such termination, remain exercisable in
         full for a period of five years after 

                                      8


         such termination (but in no event after the expiration date of any such
         Option). Options not exercisable as of such Retirement will be 
         forfeited and terminate.

              (b) All Restricted Stock Awards then held by the Participant that
         have not vested as of such termination will be terminated and
         forfeited; and

              (c) Any assignment or transfer restrictions with respect to
         Performance Stock Awards that have not lapsed will continue in effect
         in accordance with their terms unless otherwise provided in the
         agreement evidencing such Performance Stock Awards.

         9.3 TERMINATION OF EMPLOYMENT FOR REASONS OTHER THAN DEATH, 
DISABILITY OR RETIREMENT. Subject to Section 9.6 of the Plan, in the event a 
Participant's employment is terminated with the Company and all Subsidiaries 
for any reason other than death, Disability or Retirement, or a Participant 
is in the employ of a Subsidiary and the Subsidiary ceases to be a Subsidiary 
of the Company (unless the Participant continues in the employ of the Company 
or another Subsidiary):

              (a) All outstanding Options then held by the Participant will, to
         the extent exercisable as of such termination, remain exercisable in
         full for a period of three months after such termination (but in no
         event after the expiration date of any such Option). Options not
         exercisable as of such termination will be forfeited and terminate.

              (b) All Restricted Stock Awards then held by the Participant that
         have not vested as of such termination will be terminated and
         forfeited; and

              (c) Any assignment or transfer restrictions with respect to
         Performance Stock Awards that have not lapsed will continue in effect
         in accordance with their terms unless otherwise provided in the
         agreement evidencing such Performance Stock Awards.

         9.4 TERMINATION OF SERVICE AS A NON-EMPLOYEE CONSULTANT OR ADVISOR. 
In the event a Participant's service as a non-employee consultant or advisor 
is terminated with the Company and all Subsidiaries for any reason, or a 
Participant is in the service of a Subsidiary and the Subsidiary ceases to be 
a Subsidiary of the Company (unless the Participant continues in the service 
of the Company or another Subsidiary), all rights of the Participant under 
the Plan and any agreements evidencing an Incentive Award will immediately 
terminate without notice of any kind, and (i) no Options then held by the 
Participant will thereafter be exercisable, (ii) all Restricted Stock Awards 
then held by the Participant that have not vested will be terminated and 
forfeited, and (iii) any assignment or transfer restrictions with respect to 
Performance Stock Awards that have not lapsed will continue in effect in 
accordance with their terms unless otherwise provided in the agreement 
evidencing such Performance Stock Awards; provided, however, that if such 
termination is due to any reason other than termination by the Company or any 
Subsidiary for Cause (as defined in Section 2.3 of the Plan), all outstanding 
Options then held by such Participant will remain exercisable to the extent 
exercisable as of such termination for a period of three months after such 
termination (but in no event after the expiration date of any such Option).

                                      9


         9.5 MODIFICATION OF RIGHTS UPON TERMINATION. Notwithstanding the 
other provisions of this Section 9, upon a Participant's termination of 
employment or other service with the Company and all Subsidiaries, the 
Committee may, in its sole discretion (which may be exercised at any time on 
or after the date of grant, including following such termination), cause 
Options (or any part thereof) then held by such Participant to become or 
continue to become exercisable and/or remain exercisable following such 
termination of employment or other service, and Restricted Stock Awards and 
Performance Stock Awards then held by such Participant to vest and/or 
continue to vest or become free of transfer restrictions, as the case may be, 
following such termination of employment or other service, in each case in 
the manner determined by the Committee; provided, however, that (a) no 
Incentive Award will become exercisable or vest prior to six months from its 
date of grant (unless such exercisability or vesting is by reason of death or 
Disability), and (b) no Incentive Award may remain exercisable or continue to 
vest for more than two years beyond the date such Incentive Award would have 
terminated if not for the provisions of this Section 9.5 but in no event 
beyond its expiration date.

         9.6 EFFECTS OF ACTIONS CONSTITUTING CAUSE. Notwithstanding anything 
in the Plan to the contrary, in the event that a Participant is determined by 
the Committee, acting in its sole discretion, to have committed any action 
which would constitute Cause as defined in Section 2.3, irrespective of 
whether such action or the Committee's determination occurs before or after 
termination of such Participant's employment or other service with the 
Company or any Subsidiary, all rights of the Participant under the Plan and 
any agreements evidencing an Incentive Award then held by the Participant 
shall terminate and be forfeited without notice of any kind.

         9.7  DETERMINATION OF TERMINATION OF EMPLOYMENT OR OTHER SERVICE.

              (a) The change in a Participant's status from that of an employee
         of the Company or any Subsidiary to that of a non-employee consultant
         or advisor of the Company or any Subsidiary will, for purposes of the
         Plan, be deemed to result in a termination of such Participant's
         employment with the Company and its Subsidiaries, unless the Committee
         otherwise determines in its sole discretion.

              (b) The change in a Participant's status from that of a
         non-employee consultant or advisor of the Company or any Subsidiary to
         that of an employee of the Company or any Subsidiary will not, for
         purposes of the Plan, be deemed to result in a termination of such
         Participant's service as a non-employee consultant or advisor with the
         Company and its Subsidiaries, and such Participant will thereafter be
         deemed to be an employee of the Company or its Subsidiaries until such
         Participant's employment is terminated, in which event such Participant
         will be governed by the provisions of this Plan relating to termination
         of employment.

              (c) Unless the Committee otherwise determines in its sole
         discretion, a Participant's employment or other service will, for
         purposes of the Plan, be deemed to have terminated 

                                      10


         on the date recorded on the personnel or other records of the Company 
         or the Subsidiary for which the Participant provides employment, as 
         determined by the Committee in its sole discretion based upon such 
         records.

10.      PAYMENT OF WITHHOLDING TAXES.

         10.1 GENERAL RULES. The Company is entitled to (a) withhold 
and deduct from future wages of the Participant (or from other amounts 
that may be due and owing to the Participant from the Company or a 
Subsidiary), or make other arrangements for the collection of, all 
legally required amounts necessary to satisfy any and all federal, 
state and local withholding and employment-related tax requirements 
attributable to an Incentive Award, including, without limitation, the 
grant, exercise or vesting of, or payment of dividends with respect to, 
an Incentive Award or a disqualifying disposition of stock received 
upon exercise of an Incentive Stock Option, or (b) require the 
Participant promptly to remit the amount of such withholding to the 
Company before taking any action, including issuing any shares of 
Common Stock, with respect to an Incentive Award.

         10.2 SPECIAL RULES. The Committee may, in its sole discretion 
and upon terms and conditions established by the Committee, permit or 
require a Participant to satisfy, in whole or in part, any withholding 
or employment-related tax obligation described in Section 10.1 of the 
Plan by electing to tender Previously Acquired Shares, a Broker 
Exercise Notice or a combination of such methods.

11.      CHANGE IN CONTROL.

         11.1 CHANGE IN CONTROL. For purposes of this Section 11, a "Change in
Control" of the Company will mean the following:

              (a) Any "person" as such term is used in Sections 13(d) and 14(d)
         of the Exchange Act (other than the Company, any trustee or other
         fiduciary holding securities under any employee benefit plan of the
         Company, or any corporation owned, directly or indirectly, by the
         stockholders of the Company in substantially the same proportions as
         their ownership of stock of the Company), is or becomes, including
         pursuant to a tender or exchange offer for shares of Common Stock
         pursuant to which purchases are made, the "beneficial owner" (as
         defined in Rule 13d-3 under the Exchange Act), directly or indirectly,
         of securities of the Company representing 25% or more of the combined
         voting power of the Company's then outstanding securities, other than
         in a transaction arranged or approved by the Board prior to its
         occurrence; provided, however, that if any such person will become the
         beneficial owner, directly or indirectly, of securities of the Company
         representing 34% or more of the combined voting power of the Company's
         then outstanding securities, a Change in Control will be deemed to
         occur whether or not any or all of such beneficial ownership is
         obtained in a transaction arranged or approved by the Board prior to
         its occurrence, and other than in a transaction in which such person
         will have executed a written agreement with the Company (and approved
         by the Board) on or prior to the date on which such person becomes 

                                      11


         the beneficial owner of 25% or more of the combined voting power of the
         Company's then outstanding securities, which agreement imposes one or
         more limitations on the amount of such person's beneficial ownership of
         shares of Common Stock, if, and so long as, such agreement (or any
         amendment thereto approved by the Board provided that no such amendment
         will cure any prior breach of such agreement or any amendment thereto)
         continues to be binding on such person and such person is in compliance
         (as determined by the Board in its sole discretion) with the terms of
         such agreement (including such amendment); provided, however, that if
         any such person will become the beneficial owner, directly or
         indirectly, of securities of the Company representing 50% or more of
         the combined voting power of the Company's then outstanding securities,
         a Change in Control will be deemed to occur whether or not such
         beneficial ownership was held in compliance with such a binding
         agreement.

              (b) During any period of two consecutive years, individuals who at
         the beginning of such period constitute the Board, and any new director
         (other than a director designated by a person who has entered into an
         agreement with the Company to effect a transaction which would
         constitute a Change in Control pursuant to this Section 11.1) whose
         election by the Board or nomination for election by the Company's
         stockholders was approved by a vote of at least two-thirds of the
         directors then still in office who either were directors at the
         beginning of the period or whose election or nomination for election
         was previously so approved, cease for any reason to constitute at least
         a majority thereof.

              (c) The stockholders of the Company approve a merger or
         consolidation of the Company with any other corporation, other than (i)
         a merger or consolidation which would result in the voting securities
         of the Company outstanding immediately prior thereto continuing to
         represent (either by remaining outstanding or by being converted into
         voting securities of the surviving entity) more than 80% of the
         combined voting power of the voting securities of the Company or such
         surviving entity outstanding immediately after such merger or
         consolidation, or (ii) a merger or consolidation effected to implement
         a recapitalization of the Company (or similar transaction) in which no
         person acquires a percentage of the combined voting power of the
         Company's then outstanding securities which would constitute a Change
         in Control pursuant to Section 11.1 above. In case of any consolidation
         or merger of another corporation into the Company in which the Company
         is the surviving corporation and in which there is a reclassification
         or change (including a change to the right to receive cash or other
         property) of the shares of Common Stock (other than a change in par
         value, or from par value to no par value, or as a result of a
         subdivision or combination, but including any change in such shares
         into two or more classes or series of shares), Section 4.3 of the Plan
         will apply.

              (d) The stockholders of the Company approve a plan of complete
         liquidation of the Company or an agreement for the sale or disposition
         by the Company of all or substantially all of the Company's assets.

                                      12


         11.2 ACCELERATION OF VESTING. Without limiting the authority 
of the Committee under Sections 3.2 and 4.3 of the Plan, if a Change in 
Control of the Company occurs, then, if approved by the Committee in 
its sole discretion either in an agreement evidencing an Incentive 
Award at the time of grant or at any time after the grant of an 
Incentive Award, (a) all Options that have been outstanding for at 
least six months will become immediately exercisable in full and will 
remain exercisable in accordance with their terms; (b) all outstanding 
Restricted Stock Awards that have been outstanding for at least six 
months will become immediately fully vested and non-forfeitable; and 
(c) any transfer restrictions with respect to Performance Stock Awards 
will lapse.

         11.3 CASH PAYMENT FOR OPTIONS. If a Change in Control of the 
Company occurs, then the Committee, if approved by the Committee in its 
sole discretion either in an agreement evidencing an Incentive Award at 
the time of grant or at any time after the grant of an Incentive Award, 
and without the consent of any Participant affected thereby, may 
determine that some or all Participants holding outstanding Options 
will receive, with respect to some or all of the shares of Common Stock 
subject to such Options, as of the effective date of any such Change in 
Control of the Company, cash in an amount equal to the excess of the 
Fair Market Value of such shares immediately prior to the effective 
date of such Change in Control of the Company over the exercise price 
per share of such Options.

         11.4 LIMITATION ON CHANGE IN CONTROL PAYMENTS. Notwithstanding 
anything in Section 11.2 or 11.3 of the Plan to the contrary, if, with 
respect to a Participant, any of the payments to be made in connection 
with Section 11.2 or 11.3 of the Plan, together with any other payments 
or benefits which a Participant has the right to receive from the 
Company or any corporation which is a member of an "affiliated group" 
(as defined in section 1504(a) of the Code without regard to section 
1504(b) of the Code) of which the Company is a member, constitute an 
"excess parachute payment" (as defined in section 280G(b) of the Code), 
the payments to be made in connection with Section 11.2 or 11.3 of the 
Plan shall be reduced to the extent necessary to prevent any portion of 
such payments or benefits from becoming subject to the excise tax 
imposed under section 4999 of the Code; provided, however, that if a 
Participant is subject to a separate agreement with the Company or a 
Subsidiary that expressly addresses the potential application of 
Sections 280G or 4999 of the Code (including, without limitation, that 
"payments" under such agreement or otherwise will be reduced, that such 
payments will not be reduced or that the Participant will have the 
discretion to determine which "payments" will be reduced), then this 
Section 11.4 will not apply, and any "payments" to a Participant 
pursuant to Section 11.2 or 11.3 of the Plan will be treated as 
"payments" arising under such separate agreement.

                                      13


12.      RIGHTS OF ELIGIBLE RECIPIENTS AND PARTICIPANTS; 
TRANSFERABILITY.

         12.1 EMPLOYMENT OR OTHER SERVICE. Nothing in the Plan will 
interfere with or limit in any way the right of the Company or any 
Subsidiary to terminate the employment or Other Service of any Eligible 
Recipient or Participant at any time, nor confer upon any Eligible 
Recipient or Participant any right to continue in the employ or Other 
Service of the Company or any Subsidiary.

         12.2 RIGHTS AS A STOCKHOLDER. As a holder of Incentive Awards 
(other than Restricted Stock Awards and Performance Stock Awards), a 
Participant will have no rights as a stockholder unless and until such 
Incentive Awards are exercised for, or paid in the form of, shares of 
Common Stock and the Participant becomes the holder of record of such 
shares. Except as otherwise provided in the Plan, no adjustment will be 
made for dividends or distributions with respect to such Incentive 
Awards as to which there is a record date preceding the date the 
Participant becomes the holder of record of such shares, except as the 
Committee may determine in its discretion.

         12.3 RESTRICTIONS ON TRANSFER. Except pursuant to testamentary 
will or the laws of descent and distribution or as otherwise expressly 
permitted by the Plan, no right or interest of any Participant in an 
Incentive Award prior to the exercise or vesting of such Incentive 
Award will be assignable or transferable, or subjected to any lien, 
during the lifetime of the Participant, either voluntarily or 
involuntarily, directly or indirectly, by operation of law or 
otherwise. A Participant will, however, be entitled to designate a 
beneficiary to receive an Incentive Award upon such Participant's 
death, and in the event of a Participant's death, payment of any 
amounts due under the Plan will be made to, and exercise of any Options 
(to the extent permitted pursuant to Section 9 of the Plan) may be made 
by, the Participant's legal representatives, heirs and legatees.

         12.4 NON-EXCLUSIVITY OF THE PLAN. Nothing contained in the 
Plan is intended to modify or rescind any previously approved 
compensation plans or programs of the Company or create any limitations 
on the power or authority of the Board to adopt such additional or 
other compensation arrangements as the Board may deem necessary or 
desirable.

13.      SECURITIES LAW AND OTHER RESTRICTIONS.

         Notwithstanding any other provision of the Plan or any 
agreements entered into pursuant to the Plan, the Company will not be 
required to issue any shares of Common Stock under this Plan, and a 
Participant may not sell, assign, transfer or otherwise dispose of 
shares of Common Stock issued pursuant to Incentive Awards granted 
under the Plan, unless (a) there is in effect with respect to such 
shares a registration statement under the Securities Act and any 
applicable securities laws of a state or foreign jurisdiction or an 
exemption from such registration under the Securities Act and 
applicable state or foreign securities laws, and (b) there has been 
obtained any other consent, approval or permit from any other 
regulatory body which the Committee, in its sole discretion, deems 
necessary or advisable. The Company may condition such issuance, sale 
or transfer upon the receipt of any representations or agreements from 
the parties involved, and the placement of any 

                                      14


legends on certificates representing shares of Common Stock, as may be 
deemed necessary or advisable by the Company in order to comply with 
such securities law or other restrictions.

14.      PLAN AMENDMENT, MODIFICATION AND TERMINATION.

         The Board may suspend or terminate the Plan or any portion 
thereof at any time, and may amend the Plan from time to time in such 
respects as the Board may deem advisable in order that Incentive Awards 
under the Plan will conform to any change in applicable laws or 
regulations or in any other respect the Board may deem to be in the 
best interests of the Company; provided, however, that no amendments to 
the Plan will be effective without approval of the stockholders of the 
Company if stockholder approval of the amendment is then required 
pursuant to Section 422 of the Code or the rules of the New York Stock 
Exchange. No termination, suspension or amendment of the Plan may 
adversely affect any outstanding Incentive Award without the consent of 
the affected Participant; provided, however, that this sentence will 
not impair the right of the Committee to take whatever action it deems 
appropriate under Sections 3.2, 4.3 and 11 of the Plan.

15.      EFFECTIVE DATE AND DURATION OF THE PLAN.

         The Plan is effective, as amended and restated, as of May 14, 
1999 or such later date as the Plan is approved by the Company's 
stockholders and shall apply to Incentive Awards granted on or after 
such effective date. The Plan will terminate at midnight on June 30, 
2005, and may be terminated prior to such time to by Board action, and 
no Incentive Award will be granted after such termination. Incentive 
Awards outstanding upon termination of the Plan may continue to be 
exercised, or become free of restrictions, in accordance with their 
terms.

16.      MISCELLANEOUS.

         16.1 GOVERNING LAW. The validity, construction, 
interpretation, administration and effect of the Plan and any rules, 
regulations and actions relating to the Plan will be governed by and 
construed exclusively in accordance with the laws of the State of 
Minnesota, notwithstanding the conflicts of laws principles of any 
jurisdictions.

         16.2 SUCCESSORS AND ASSIGNS. The Plan will be binding upon and 
inure to the benefit of the successors and permitted assigns of the 
Company and the Participants.

                                      15
