                                        3



            a. Without limiting Buyer's right to sell the Common Stock pursuant
to the Registration Statement, the Buyer is purchasing the Preferred Stock and

            d. The Buyer understands that the Securities are being issued in a
private placement and are being offered and sold to it in reliance on specific
exemptions from the registration requirements of United States federal and state
securities laws and that the Company is relying upon the truth and accuracy of,
and the Buyer's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of the Buyer set forth herein in order to

Buyer enforceable in accordance with its terms, subject as to enforceability to
general principles of equity and to bankruptcy, insolvency, moratorium and other
similar laws affecting the enforcement of creditors' rights generally.

            i. The Buyer acknowledges that, with respect to the offering of the
Securities, no general solicitation or general advertising (including
communications published in any newspaper, magazine or other broadcast medium)
has been received by the Buyer and no public solicitation or advertisement has
been made to the Buyer.

            j. There is no investment banker, broker, finder or other similar
intermediary which has been retained by, or is authorized by, the Buyer or any

entitled to any fee or commission from the Company in connection with the
purchase and sale of the Securities.

            3. COMPANY REPRESENTATIONS, ETC. The Company represents and warrants
to the Buyer as of the date hereof and as of the Closing Date that, except as
otherwise provided in ANNEX V hereto:

            a. CONCERNING THE PREFERRED STOCK AND THE SHARES. The Preferred
Stock has been duly authorized, and when issued and paid for in accordance with
the terms of this Agreement, will be duly and validly issued, fully paid and
non-assessable and will not subject the holder thereof to personal liability
solely by reason of acquiring the Preferred Stock hereunder. There are no
preemptive rights of any stockholder of the Company, as such, to acquire the
Preferred Stock, the Warrants or the Shares.

            b. REPORTING COMPANY STATUS. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Minnesota and has the requisite corporate power to own its properties and to
carry on its business as now being conducted. The Company is duly qualified as a
foreign corporation to do business and is in good standing in each jurisdiction
where the nature of the business conducted or property owned by it makes such
qualification necessary, other than those jurisdictions in which the failure to
so qualify would not have a material adverse effect on the business, operations
or financial condition or results of operation of the Company. The Company has
registered its Common Stock pursuant to Section 12 of the 1934 Act, and the
Common Stock is quoted and traded on The NASDAQ/Bulletin Board Market. The
Company has received no notice, either oral or written, with respect to the
continued eligibility of the Common Stock for such listing, and the Company has
maintained all requirements for the continuation of such quotation.

Securities, and the consummation by the Company of the other transactions
contemplated by this Agreement, the Registration Rights Agreement, and the
Preferred Stock do not and will not conflict with or result in a breach by the
Company of any of the terms or provisions of, or constitute a default under (i)
the articles of incorporation or by-laws of the Company, each as currently in
effect, (ii) any indenture, mortgage, deed of trust, or other material agreement
or instrument to which the Company is a party or by which it or any of its
properties or assets are bound, including any listing agreement for the Common

in the Company's SEC Documents) that has not been disclosed in writing to the
Buyer that (i) would reasonably be expected by the Company to have a material
adverse effect on the business, operations or financial condition of the Company

be expected to materially and adversely affect the ability of the Company to

                                        7



public board or body pending or, to the knowledge of the Company, threatened
against the Company, wherein an unfavorable decision, ruling or finding would
have a material adverse effect on the properties, business, operations or

affect the validity or enforceability of, or the authority or ability of the
Company to perform its obligations under, any of the Transaction Agreements.

            k. ABSENCE OF EVENTS OF DEFAULT. The Company is not in default in
the performance or observance of any material obligation, agreement, covenant or

property is bound. Except as set forth in Section 3(e) hereof, no Event of
Default (or its equivalent term), as defined in the respective agreement to
which the Company is a party, and no event which, with the giving of notice or
the passage of time or both, would become an Event of Default (or its equivalent
term) (as so defined in such agreement), has occurred and is continuing, which
would have a material adverse effect on the business, operations or the
financial condition or results of operations of the Company and its
subsidiaries, taken as a whole.

            l. PRIOR ISSUES. Except as disclosed in the SEC Documents, during
the twelve (12) months preceding the date hereof, the Company has not issued any

operations, financial condition or results of operations of the Company. No
event or circumstances has occurred or exists with respect to the Company or its
properties, business, operations, financial condition, or results of operations,
which, under applicable law, rule or regulation, requires public disclosure or
announcement prior to the date hereof by the Company but which has not been so
publicly announced or disclosed. There are no proposals currently under
consideration or currently anticipated to be under consideration by the Board of
Directors or the executive officers of the Company which proposal would (x)
change the certificate of incorporation or other charter document or by-laws of
the Company, each as currently in effect, with or without shareholder approval,
which change would reduce or otherwise adversely affect the rights and powers of
the shareholders of the Common Stock or (y) materially or substantially change
the business, assets or capital of the Company.

            n. NO INTEGRATED OFFERING. Neither the Company nor any of its
affiliates nor any person acting on its or their behalf has, directly or

security or solicited any offers to buy any security under circumstances that
would eliminate the availability of the exemption from registration under Rule
506 of Regulation D in connection with the offer and sale of the Securities as
contemplated hereby.


                                        8



            o. DILUTION. The number of Shares issuable upon conversion of the
Preferred Stock and the exercise of the Warrants may increase substantially in
certain circumstances, including, but not necessarily limited to, the
circumstance wherein the trading price of the Common Stock declines prior to the
conversion of the Preferred Stock. The Company's executive officers and
directors have studied and fully understand the nature of the Securities being
sold hereby and recognize that they have a potential dilutive effect. The board
of directors of the Company has concluded, in its good faith business judgment,
that such issuance is in the best interests of the Company. The Company
specifically acknowledges that its obligation to issue the Shares upon
conversion of the Preferred Stock and upon exercise of the Warrants is binding
upon the Company and enforceable regardless of the dilution such issuance may
have on the ownership interests of other shareholders of the Company.

            4. CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

            a. TRANSFER RESTRICTIONS. The Buyer acknowledges that (1) the
Preferred Stock and the Warrants have not been and are not being registered
under the provisions of the 1933 Act and, except as provided in the Registration
Rights Agreement, the Shares have not been and are not being registered under
the 1933 Act, and may not be transferred unless (A) subsequently registered
thereunder or (B) the Buyer shall have delivered to the Company an opinion of
counsel, reasonably satisfactory in form, scope and substance to the Company, to
the effect that the Securities to be sold or transferred may be sold or
transferred pursuant to an exemption from such registration; (2) any sale of the
Securities made in reliance on Rule 144 promulgated under the 1933 Act may be
made only in accordance with the terms of said Rule and further, if said Rule is
not applicable, any resale of such Securities under circumstances in which the
seller, or the person through whom the sale is made, may be deemed to be an
underwriter, as that term is used in the 1933 Act, may require compliance with
some other exemption under the 1933 Act or the rules and regulations of the SEC
thereunder; and (3) neither the Company nor any other person is under any
obligation to register the Securities (other than pursuant to the Registration
Rights Agreement) under the 1933 Act or to comply with the terms and conditions
of any exemption thereunder.

            b. RESTRICTIVE LEGEND. The Buyer acknowledges and agrees that the
Preferred Stock and the Warrants, and, until such time as the Common Stock has
been registered under the 1933 Act as contemplated by the Registration Rights
Agreement and sold in accordance with an effective Registration Statement,
certificates and other instruments representing any of the Securities shall bear
a restrictive legend in substantially the following form (and a stop-transfer
order may be placed against transfer of any such Securities):

            THESE SECURITIES (THE "SECURITIES") HAVE NOT BEEN
            REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

            ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE
            SECURITIES OR AN OPINION OF


                                        9



            COUNSEL OR OTHER EVIDENCE ACCEPTABLE TO THE CORPORATION
            THAT SUCH REGISTRATION IS NOT REQUIRED.

            c. FILINGS. The Company undertakes and agrees to make all necessary
filings in connection with the sale of the Securities to the Buyer under any
United States laws and regulations applicable to the Company, or by any domestic
securities exchange or trading market, and to provide a copy thereof to the
Buyer promptly after such filing.

            d. REPORTING STATUS. So long as the Buyer beneficially owns any of
the Securities, the Company shall file all reports required to be filed with the
SEC pursuant to Section 13 or 15(d) of the 1934 Act, and the Company shall not
terminate its status as an issuer required to file reports under the 1934 Act
even if the 1934 Act or the rules and regulations thereunder would permit such
termination. The Company will take all reasonable action under its control to
obtain and to continue the quotation and trading of its Common Stock (including,
without limitation, all Registrable Securities) on The NASDAQ/Bulletin Board
Market and will comply in all material respects with the Company's reporting,
filing and other obligations under the by-laws or rules of the National

and escrow fees in connection with the sale of the Preferred Stock) for internal
working capital purposes, and, unless specifically consented to in advance in
each instance by the Buyer, the Company shall not, directly or indirectly, use
such proceeds for any loan to or investment in any other corporation,
partnership enterprise or other person or for the repayment of any outstanding
loan by the Company to any other party.

            f. AVAILABLE SHARES. The Company shall have at all times authorized
and reserved for issuance, free from preemptive rights, shares of Common Stock
sufficient to yield two hundred percent (200%) of the number of shares of Common
Stock issuable (i) at conversion as may be required to satisfy the conversion
rights of the Buyer pursuant to the terms and conditions of the Certificate of
Designations or to represent payment of dividends on the Preferred Stock and
(ii) upon exercise as may be required to satisfy the exercise rights of the
Buyer pursuant to the terms and conditions of the Warrants.

            g. WARRANTS. The Company agrees to issue to the Buyer on the Closing
Date transferable, divisible warrants (the "Warrants") for the purchase of ten
thousand (10,000) shares of Common Stock for each $100,000 of liquidation
preference of the Preferred Stock. The Warrants shall bear an exercise price
equal to one hundred ten percent (110%) of the Initial Market Price. The
Warrants will expire on the last day of the calendar month in which the fifth
anniversary of the Closing Date occurs. The Warrants shall be in the form
annexed hereto as ANNEX VI, together with (x) registration rights as provided in

            h. LIMITATION ON ISSUANCE OF SHARES. If at any time (the "Limited
Availability Date") the number of outstanding but unissued shares of Common
Stock of the Company is less than seventy-five percent (75%) of the number of
shares contemplated by Section 4(f) hereof, the Company shall take all steps,
including but not necessarily limited to, obtaining board authorization, holding
an annual or special shareholders' meeting, issuing a proxy statement, having a
vote of shareholders and filing an amendment to the Company's charter documents,
necessary to increase the authorized shares of Common Stock of the Company so
that the provisions of said Section 4(f) shall be satisfied, except that the
percentage shall be 250%.

            j. RIGHT OF FIRST REFUSAL. (i) The Company covenants and agrees that
if during the period from the date hereof through and including the date which
is two hundred seventy (270) days after the Effective Date, the Company offers
to enter into any transaction (a "New Transaction") for the sale of New Common
Stock, the Company shall notify the Buyer in writing of all of the terms of such
offer (a "New Transaction Offer"). The Buyer shall have the right (the "Right of
First Refusal"), exercisable by written notice given to the Company by the close
of business on the fifth business day after the Buyer's receipt of the New
Transaction Offer (the "Right of First Refusal Expiration Date"), to participate
in all or any part of the New Transaction Offer on the terms so specified. If
and to the extent the Buyer elects to participate in the New Transaction, the
Buyer shall be obligated to do on the same terms as provided in the New
Transaction on the date which is the earlier of the date specified in the New
Transaction or ten (10) business days after the Right of First Refusal
Expiration Date.

            (ii) If, and only if, the Buyer does not exercise the Right of First
Refusal in full, the Company may consummate the remaining portion of the New
Transaction with any New Investor on the terms specified in the New Transaction
Offer within thirty (30) days of the Right of First Refusal Expiration Date.

            (iii) If the terms of the New Transaction to be consummated with
such other party differ from the terms specified in the New Transaction Offer so
that the terms are more economically beneficial in any respect to the New
Investor, the Company shall give the Buyer a New Transaction Offer relating to
the terms of the New Transaction, as so changed, and the Buyer's Right of First
Refusal and the preceding terms of this paragraph (j) shall apply with respect
to such changed terms.

            k. SHORT SALES. The Buyer and its affiliates shall not engage in
short sales of the Company's Common Stock; provided, however, that the Buyer or
its affiliates may enter into any short sale of other hedging or similar
arrangement it deems appropriate with respect to that number of shares of Common
Stock equal to the number of the Converted Shares covered by a particular Notice
of Conversion, commencing on the day the Buyer delivers such Notice of
Conversion (as contemplated by Section 5 hereof), and terminating on the
Delivery Date with respect to such Converted Shares or later date that such
Converted Shares are delivered to Buyer.

            5. TRANSFER AGENT INSTRUCTIONS.


                                       11



            a. Promptly following the delivery by the Buyer of the Purchase
Price in accordance with Section 1(c) hereof, the Company will irrevocably
instruct its transfer agent to issue Common Stock from time to time upon
conversion of the Preferred Stock in such amounts as specified from time to time
by the Company to the transfer agent, bearing the restrictive legend specified
in Section 4(b) of this Agreement prior to registration of, and sale of the
Shares under the 1933 Act, registered in the name of the Buyer or its nominee
and in such denominations to be specified by the Buyer in connection with each
conversion of the Preferred Stock. The Company warrants that no instruction
inconsistent with the instructions referred to in this Section 5 and the stop
transfer instructions to give effect to Section 4(a) hereof prior to
registration and sale of the Shares under the 1933 Act will be given by the
Company to the transfer agent with respect to the Shares and that the Shares
shall otherwise be freely transferable on the books and records of the Company
as and to the extent provided in this Agreement, the Registration Rights
Agreement, and applicable law. Nothing in this Section shall affect in any way
the Buyer's obligations and agreement to comply with all applicable securities
laws upon resale of the Securities. If the Buyer provides the Company with an
opinion of counsel reasonably satisfactory to the Company that registration of a
resale by the Buyer of any of the Securities in accordance with clause (1)(B) of
Section 4(a) of this Agreement is not required under the 1933 Act, the Company
shall (except as provided in clause (2) of Section 4(a) of this Agreement)
permit the transfer of the Securities and, in the case of the Converted Shares
or the Warrant Shares, as the case may be, promptly instruct the Company's
transfer agent to issue one or more certificates for Common Stock in accordance
with such opinion of counsel in such name and in such denominations as specified
by the Buyer.

            b. (i) The Company will permit the Buyer to exercise its right to
convert the Preferred Stock by telecopying or delivering an executed and
completed Notice of Conversion, setting forth the Conversion Date (as defined
below) and the number of Converted Shares issuable upon such conversion
calculated in accordance with the Certificate of Designations, to the Company
and delivering, within five (5) business days thereafter, the original Preferred
Stock being converted to the Company by express courier, with a copy to the
transfer agent.

               (ii) The term "Conversion Date" means, with respect to any
conversion elected by the holder of the Preferred Stock, the date specified in
the Notice of Conversion, provided the copy of the Notice of Conversion is
telecopied to or otherwise delivered to the Company in accordance with the
provisions hereof so that it is received by the Company on or before such
specified date.

               (iii) The Company will transmit the certificates representing the
Converted Shares issuable upon conversion of any Preferred Stock (together with,
unless otherwise instructed by the Buyer, one or more certificates representing
the Preferred Stock not being so converted if the certificates submitted in
connection with such conversion represented more shares than then being
converted) to the Buyer at the address specified in the Notice of Conversion
(which may be the Buyer's address for notices as contemplated by Section 11
hereof or a different address) via recognized express or overnight courier, by
electronic transfer or otherwise, within three (3) business days (such third
business day, the "Delivery Date") after (A)


                                       12



the business day on which the Company has received both of the Notice of
Conversion prepared in accordance with Section 5(b)(i) (by facsimile or other
delivery) and the original Preferred Stock being converted (and if the same are
not delivered to the Company on the same date, the date of delivery of the
second of such items) or (B) the date a dividend payment on the Preferred Stock
which the Company has elected to pay by the issuance of Common Stock, as
contemplated by the Preferred Stock, was due.

            c. The Company understands that a delay in the issuance of the
Shares of Common Stock beyond the Delivery Date could result in economic loss to
the Buyer. As compensation to the Buyer for such loss, the Company agrees to pay
late payments to the Buyer for late issuance of Shares upon conversion in
accordance with the following schedule (where "No. Business Days Late" is
defined as the number of business days beyond two (2) business days from the
Delivery Date):

                                            Late Payment For Each $10,000
                                        of Liquidation Preference or Dividend
              No. Business Days Late            Amount Being Converted
              ----------------------    -------------------------------------

                       1                        $100
                       2                        $200
                       3                        $300
                       4                        $400
                       5                        $500
                       6                        $600
                       7                        $700
                       8                        $800
                       9                        $900
                       10                       $1,000
                      >10                       $1,000 + $200 for each Business
                                                Day Late beyond 10 days

The Company shall pay any payments incurred under this Section in immediately
available funds upon demand. Furthermore, in addition to any equitable remedies
which may be available to the Buyer, in the event that the Company fails for any
reason to effect delivery of such shares of Common Stock within two (2) business
days after the Delivery Date, the Buyer will be entitled to revoke the relevant
Notice of Conversion by delivering a notice to such effect to the Company
whereupon the Company and the Buyer shall each be restored to their respective
positions immediately prior to delivery of such Notice of Conversion.

            d. If, by the relevant Delivery Date, the Company fails for any
reason to deliver the Shares to be issued upon conversion of Preferred Stock,
and after such Delivery Date, the holder of the Preferred Stock being converted
(a "Converting Holder") purchases, in an


                                       13



arm's-length open market transaction or otherwise, shares of Common Stock (the
"Covering Shares") in order to make delivery in satisfaction of a sale of Common
Stock by the Converting Holder (the "Sold Shares"), which delivery such
Converting Holder anticipated to make using the Shares to be issued upon such
conversion (a "Buy-In"), the Company shall pay to the Converting Holder, in
addition to all other amounts contemplated in Section 5(c), and not in lieu
thereof, the Buy-In Adjustment Amount (as defined below). The "Buy-In Adjustment
Amount" is the amount equal to the excess, if any, of (x) the Converting
Holder's total purchase price (including brokerage commissions, if any) for the
Covering Shares over (y) the net proceeds (after brokerage commissions, if any)
received by the Converting Holder from the sale of the Sold Shares. The Company
shall pay the Buy-In Adjustment Amount to the Converting Holder in immediately
available funds immediately upon demand by the Converting Holder. By way of
illustration and not in limitation of the foregoing, if the Converting Holder
purchases shares of Common Stock having a total purchase price (including
brokerage commissions) of $11,000 to cover a Buy-In with respect to shares of
Common Stock it sold for net proceeds of $10,000, the Buy-In Adjustment Amount
which Company will be required to pay to the Converting Holder will be $1,000.

            e. In lieu of delivering physical certificates representing the
Common Stock issuable upon conversion, provided the Company's transfer agent is
participating in the Depository Trust Company ("DTC") Fast Automated Securities
Transfer program, upon request of the Buyer and its compliance with the
provisions contained in this paragraph, so long as the certificates therefor do
not bear a legend and the Buyer thereof is not obligated to return such
certificate for the placement of a legend thereon, the Company shall use its
best efforts to cause its transfer agent to electronically transmit the Common
Stock issuable upon conversion to the Buyer by crediting the account of Buyer's
Prime Broker with DTC through its Deposit Withdrawal Agent Commission system.

            f. If, at any time (i) the Company challenges, disputes or denies
the right of a holder of Preferred Stock to effect a conversion of the Preferred
Stock into Common Stock or otherwise dishonors or rejects any Conversion Notice
delivered in accordance with the terms of this Agreement or the Certificate of
Designations or any exercise of any Warrant in accordance with its terms
("Warrant Exercise"), or (ii) any third party who is not and has never been an
Affiliate of such holder commences any lawsuit or proceeding or otherwise
asserts any claim before any court or public or governmental authority, which
lawsuit, proceeding or claim seeks to challenge, deny, enjoin, limit, modify,
delay or dispute the right of such holder to effect the conversion of the
Preferred Stock into Common Stock, and the Company refuses to honor any such
Conversion Notice or Warrant Exercise, then such holder shall have the right, by
written notice to the Company, to require the Company to promptly redeem the
Preferred Stock for cash at a redemption price (the "Mandatory Purchase Amount")
equal to (x) one hundred twenty-two percent (122%) of the liquidation preference
of the unconverted Preferred Stock held by such holder plus (y) all accrued but
unpaid dividends on the Preferred Stock through the date of payment of the
Mandatory Purchase Amount. Under any of the circumstances set forth above, the
Company shall be responsible for the payment of all costs and expenses of such
holder, including, but not necessarily limited to, reasonable legal fees and
expenses, as and when incurred


                                       14



in connection with such holder's disputing any such action or pursuing such
holder's rights hereunder (in addition to any other rights such holder may have
hereunder or otherwise). The Mandatory Purchase Amount will be payable to such
holder in cash within five (5) business days from the date such holder gives the
Company written notice that it is exercising its rights under this paragraph.

            g. The holder of any Preferred Stock shall be entitled to exercise
its conversion privilege with respect to the Preferred Stock notwithstanding the
commencement of any case under 11 U.S.C. ss.101 et seq. (the "Bankruptcy Code").
In the event the Company is a debtor under the Bankruptcy Code, the Company
hereby waives, to the fullest extent permitted, any rights to relief it may have
under 11 U.S.C. ss.362 in respect of such holder's conversion privilege. The
Company hereby waives, to the fullest extent permitted, any rights to relief it
may have under 11 U.S.C. ss.362 in respect of the conversion of the Preferred
Stock. The Company agrees, without cost or expense to such holder, to take or to
consent to any and all action necessary to effectuate relief under 11 U.S.C.
ss.362.

            h. The Company will authorize its transfer agent to give information
relating to the Company directly to the Buyer or the Buyer's representatives
upon the request of the Buyer or any such representative. The Company will
provide the Buyer with a copy of the authorization so given to the transfer
agent.

            6. CLOSING DATE.

            a. The Closing Date shall occur on the date which is the first NYSE
