                                       2


<PAGE>   3


Company may designate by notice to the holder hereof). The Company agrees
and acknowledges that the shares of Common Stock so purchased shall be deemed to
be issued to the presenting Warrantholder as the record owner of such shares as
of the close of business on the date on which this Warrant, properly endorsed,
and the Subscription Form shall have been surrendered and payment made for such
shares. Upon receipt thereof, the Company shall, as promptly as practicable,
execute or cause to be executed and deliver to the Warrantholder, a certificate
or certificates representing the aggregate number of shares of Common Stock
specified in said Subscription Form. Each stock certificate so delivered shall
be in such denomination as may be requested by the Warrantholder and shall be
registered in the name of the Warrantholder. If this Warrant shall have been
exercised only in part, the Company shall, at the time of delivery of said stock
certificate or certificates, deliver to the Warrantholder a new Warrant
evidencing the rights of such holder to purchase the remaining shares of Common
Stock covered by this Warrant. The Company shall pay all expenses, taxes and
other charges payable in connection with the preparation, execution and delivery
of stock certificates pursuant to this Section 2, except that, in case any such
stock certificate or certificates shall be registered in a name or names other
than the name of the Warrantholder, funds sufficient to pay all stock transfer
taxes which shall be payable upon the execution and delivery of such stock
certificate or certificates shall be paid by the Warrantholder to the Company at
the time of delivering this Warrant to the Company as mentioned above.

         3.       Ownership of this Warrant. The Company may deem and treat the
registered Warrantholder as the holder and owner hereof (notwithstanding any
notations of ownership or writing made hereon by anyone other than the Company)
for all purposes and shall not be affected by any notice to the contrary, until
presentation of this Warrant for transfer as provided herein and then only if
such transfer meets the requirements of Section 5 hereof

         4.       Exchange, Transfer and Replacement. Subject to Section 5
hereof, this Warrant is exchangeable upon the surrender hereof by the
Warrantholder to the Company at its office or agency described in Section 2
hereof for new Warrants of like tenor and date representing in the aggregate the
right to purchase the number of shares purchasable hereunder, each of such new
Warrants to represent the right to purchase such number of shares (not to exceed
the aggregate total number purchasable hereunder) as shall be designated by the
Warrantholder at the time of such surrender. Subject to Section 5 hereof, this
Warrant and all rights hereunder are transferable, in whole or in part, upon the
books of the Company by the Warrantholder in person or by duly authorized
attorney, and a new Warrant of the same tenor and date as this Warrant, but
registered in the name of the transferee, shall be executed and delivered by the
Company upon surrender of this Warrant, duly endorsed, at said office or agency
of the Company. Upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction, or mutilation of this Warrant, and, in
case of loss, theft, or destruction, of indemnity or security reasonably
satisfactory to it, and upon surrender and cancellation of this Warrant, if
mutilated, the Company will make and deliver a new Warrant of like tenor, in
lieu of this Warrant. This Warrant shall be promptly canceled by the Company
upon the surrender hereof in connection with any exchange, transfer or
replacement. The Company shall pay all expenses, taxes (other than stock
transfer taxes), and other charges payable in connection with the preparation,
execution, and delivery of Warrants pursuant to this Section 4.

         5.       Restrictions on Transfer. Notwithstanding any provisions
contained in this Warrant to the contrary, neither this Warrant, nor the Warrant
Shares, shall be transferable except upon the conditions specified in this
Section 5, which conditions are intended, among other things, to ensure
compliance with the provisions of the Securities Act in respect of the transfer
of this Warrant or such Warrant Shares. The holder of this Warrant agrees that
such holder will not transfer this Warrant, nor the related Warrant Shares: (a)
prior to delivery to the Company of an opinion of counsel satisfactory to the
Company and its counsel stating that such transfer is exempt from registration
under the Securities Act and applicable state securities laws; or (b) until
registration of such Warrants and/or Warrant Shares under the Securities Act has
become effective and continues to be effective at the time of such transfer. An
appropriate legend may be endorsed on the Warrants and the certificates
representing the Warrant Shares evidencing these restrictions, and a stop order
may be placed on the Company's transfer records.

         6.       Antidilution Provisions. The rights granted hereunder are
subject to the following:

                  (a)      Adjustment of Purchase Price. The Purchase Price
         shall be subject to adjustment from time to time as hereinafter
         provided. Upon each adjustment of the Purchase Price, the Warrantholder
         shall thereafter be entitled to purchase, at the Purchase Price
         resulting from such adjustment, the number of shares obtained by
         multiplying the Purchase Price in effect immediately prior to such
         adjustment by the number of shares purchasable pursuant hereto
         immediately prior to such adjustment and dividing the product thereof
         by the Purchase Price resulting from such adjustment;

                  (b)      Stock Split, Stock Dividends and Reverse Splits. In
         case the Company shall at any time divide the outstanding shares of its
         Common Stock into a greater number of shares (whether pursuant to a
         stock split, stock dividend or otherwise), and conversely, in case the
         outstanding shares of its Common Stock shall be combined into a smaller
         number of shares, the Purchase Price in effect immediately prior to
         such division or combination shall be proportionately adjusted to
         reflect the reduction or increase in the value of each such share of
         Common Stock;

                  (c)      Reorganization, Consolidation, Merger or Sale of
         Assets. If any capital reorganization or reclassification of the
         capital stock of the Company, or consolidation or merger of the Company
         with another corporation, or the sale of all or substantially all of
         its assets to another corporation shall be effected in such a way that
         holders of the Company's Common Stock shall be entitled to receive
         stock, securities or assets with respect to or in exchange for such
         common shares, then, as a condition of such reorganization,
         reclassification, consolidation, merger or sale, the holder of this
         Warrant shall have the right to purchase and receive upon the basis and
         upon the terms and conditions specified in this Warrant, and in lieu of
         the shares of the Common Stock of the Company immediately theretofore
         purchasable and receivable upon the exercise of the rights represented
         hereby, such shares of stock, other securities or assets as would have
         been issued or delivered to the holder of this Warrant if it had
         exercised this Warrant and had received such shares of


                                       4



<PAGE>   5


         Common Stock prior to such reorganization, reclassification,
         consolidation, merger or sale. The Company shall not effect any such
         consolidation, merger or sale, unless prior to the consummation thereof
         the successor corporation (if other than the Company) resulting from
         such consolidation or merger or the corporation purchasing such assets
         shall assume by written instrument executed and mailed to the
         registered holder of this Warrant at the last address of such holder
         appearing on the books of the Company, the obligation to deliver to
         such holder such shares of stock, securities or assets as, in
         accordance with the foregoing provisions, such holder may be entitled
         to purchase;

                  (d)      Other Actions. Provided, however, that the issuance
         of additional capital stock of the Company to persons other than the
         Warrantholder in a manner not discussed in this Section 6 shall not
         result in any adjustment in the Purchase Price or increase in the
         number of shares subject to this Warrant; and

                  (e)      Notice. Upon any adjustment of the Purchase Price,
         the Company shall give written notice thereof, by first class mail,
         postage prepaid, addressed to the registered Warrantholder at the
         address of such holder as shown on the books of the Company, which
         notice shall state the Purchase Price resulting from such adjustment
         and the increase or decrease, if any, in the number of shares
         purchasable at such price upon the exercise of this Warrant, setting
         forth in reasonable detail the method of calculation and the acts upon
         which such calculation is based.

                  7.       Special Agreements of the Company. The Company
         covenants and agrees that:

                  (a)      Will Reserve Shares. The Company will reserve and set
         apart and have at all times, free from preemptive rights, the number of
         shares of authorized but unissued Common Stock deliverable upon the
         exercise of the Warrants, and it will have at all times any other
         rights or privileges provided for herein sufficient to enable it at any
         time to fulfill all of its obligations hereunder;

                  (b)      Will Secure Governmental Approvals. If any shares of
         Common Stock required to be reserved for the purposes of exercise of
         the Warrants require registration with or approval of any governmental
         authority under any federal law (other than the Securities Act) or
         under any state law before such shares may be issued upon exercise of
         the Warrants, the Company, will, at its exercise of the Warrants, the
         Company will, at its expense, as expeditiously as possible, use its
         best efforts to cause such shares to be duly registered or approved, as
         the case may be;

                  (c)      Will Open Books. The Company will keep its books open
         for transfer of any Warrant and/or Warrant Shares except as otherwise
         provided by law; and

                  8.       Notices. Any notice or other document required or
         permitted to be given or delivered to Warrantholders shall be delivered
         or sent by certified mail to each


                                       5

<PAGE>   6

         Warrantholder at the last address shown on the books of the Company
         maintained for the registry and transfer of the Warrants. Any notice or
         other document required or permitted to be given or delivered to the
         Company shall be delivered or sent by certified mail to the principal
         office of the Company located at 8091 Wallace Road, Eden Prairie,
         Minnesota 55344, or such other address as shall have been furnished to
         the Warrantholders by the Company.

                  9.       No Rights as Shareholders: Limitation of Liability.
         This Warrant shall not entitle any holder hereof to any of the rights
         of a shareholder of the Company. No provision hereof, in the absence of
         affirmative action by the holder hereof to purchase shares of Common
         Stock, and no mere enumeration herein of the rights or privileges of
         the holder hereof, shall give rise to any liability of such holder for
         the Purchase Price or as a shareholder of the Company, whether such
         liability is asserted by the Company or by creditors of the Company.

                  10.      Governing Law. This Warrant shall be governed by, and
         construed under and in accordance with, the laws of the State of
         Minnesota.

                  11.      Miscellaneous. This Warrant and any provision hereof
         may be changed, waived, discharged or terminated only by an instrument
         in writing signed by the party (or any predecessor in interest thereof)
         against which enforcement of the same is sought. The headings in this
         Warrant are for purposes of reference only and shall not affect the
         meaning or construction of any of the provisions hereof.

         IN WITNESS WHEREOF, the Company has caused this Warrant to be signed by
a duly authorized officer and attested effective the 1st day of April, 1998.

                     TO BE EXECUTED BY THE REGISTERED HOLDER
             IF IT DESIRES TO EXERCISE, IN PART, THE WITHIN WARRANT


         The undersigned hereby exercises the right to purchase               of
the total shares of Common Stock covered by the within Warrant at the date of

shares not subscribed for shall be issued in the name of and delivered to the
undersigned, unless otherwise specified by written instructions, signed by the
undersigned and accompanying this subscription. I realize that this is a

         AND NUMBER OF SHARES OF COMMON STOCK SPECIFIED IN THE WITHIN WARRANT

the nearest whole share) resulting from adjustment of           shares of the
total of             shares of Common Stock covered by the within Warrant, as
said shares were constituted at the date of the Warrant.

         I understand that the Company is issuing these shares to me in
