THIS WARRANT AND THE STOCK ISSUABLE UPON THE EXERCISE HEREOF HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND CAN BE
TRANSFERRED ONLY IN COMPLIANCE WITH THE ACT AND APPLICABLE STATE SECURITIES
LAWS. THIS WARRANT AND SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED
IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT, UNLESS, IN THE OPINION OF
COUNSEL FOR THE COMPANY OR COUNSEL FOR THE REGISTERED HOLDER (WHICH SHALL BE IN
FORM AND FROM SUCH COUNSEL AS SHALL BE REASONABLY SATISFACTORY TO THE COMPANY),
SUCH REGISTRATION IS NOT THEN REQUIRED.

                              GLOBAL MAINTECH CORP.
                          COMMON STOCK PURCHASE WARRANT

     1. Issuance. In consideration of good and valuable consideration, the
receipt of which is hereby acknowledged by Global MAINTECH Corp., a Minnesota
corporation (the "Company"), Nash, LLC, a Cayman Islands limited liability
company, or registered assigns (the "Holder") is hereby granted the right to
purchase at any time until 5:00 P.M., Pacific Coast time, on December 30, 2004
(the "Expiration Date"), Fifty Thousand (50,000) fully paid and nonassessable
shares of the Company's Common Stock, no par value per share (the "Common
Stock") at an exercise price of $5.125 per share (the "Exercise Price") subject
to further adjustment as set forth in Section 6 hereof.

     2. Exercise of Warrants. This Warrant is exercisable in whole or in part
for whole shares of the Company's Common Stock at the Exercise Price per share
of Common Stock payable hereunder, payable in cash or by certified or official
bank check. In lieu of paying cash to exercise this Warrant, the Holder may, by
designating a "cashless" exercise on the Notice of Exercise Form, acquire a
number of whole shares of the Company's Common Stock equal to (a) the difference
between (i) the Market Value of the Company's Common Stock and (ii) the Exercise
Price, multiplied by (b) the number of shares of Common Stock purchasable under
the portion of the Warrant tendered to the Company, divided by (c) the Market
Value of the Company's Common Stock. Upon surrender of this Warrant Certificate
with the annexed Notice of Exercise Form duly executed, together with payment of
the Exercise Price for the shares of Common Stock purchased, the Holder shall be
entitled to receive a certificate or certificates for the shares of Common Stock
so purchased. For the purposes of this Section 2, "Market Value" shall be an
amount equal to the average closing bid price of a share of Common Stock for the
five (5) business days immediately preceding the Company's receipt of the Notice
of Exercise Form duly executed.

     3. Reservation of Shares. The Company hereby agrees that at all times
during the term of this Warrant there shall be reserved for issuance upon
exercise of this Warrant such number of shares of its Common Stock as shall be
required for issuance upon exercise of this Warrant (the "Warrant Shares").

     4. Mutilation or Loss of Warrant. Upon receipt by the Company of evidence
satisfactory to it of the loss, theft, destruction or mutilation of this
Warrant, and (in the case of loss, theft or destruction) receipt of reasonably
satisfactory indemnification, and (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will execute and deliver a new
<PAGE>

Warrant of like tenor and date and any such lost, stolen, destroyed or mutilated
Warrant shall thereupon become void.

     5. Rights of the Holder. The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in this Warrant and
are not enforceable against the Company except to the extent set forth herein.

     6. Adjustments to Exercise Terms.

     If the Company at any time prior to the full execution of this Warrant
shall, by subdivision, combination, merger, spin-off, re-classification or like
capital adjustment of the securities, change any of the securities to which
purchase rights under this Warrant exist into the same or different number of
securities of any class or classes, this Warrant shall thereafter entitle the
Holder to acquire such number and kind of securities as would have been issuable
as a result of such change with respect to the securities acquirable immediately
prior to such transaction. If shares of the securities acquirable upon exercise
of this Warrant are subdivided into a greater number of securities, including
any stock dividend, or if such securities are combined into a lesser number of
securities, then the purchase price for the securities acquirable upon exercise
of this Warrant and the securities acquirable pursuant to this Warrant shall be
proportionately and equitably adjusted.

     7. Transfer to Comply with the Securities Act; Registration Rights.

          (a) This Warrant has not been registered under the Securities Act of
     1933, as amended, (the "Act") and has been issued to the Holder for
     investment and not with a view to the distribution of either the Warrant or
     the Warrant Shares. Neither this Warrant nor any of the Warrant Shares or
     any other security issued or issuable upon exercise of this Warrant may be
     sold, transferred, pledged or hypothecated in the absence of an effective
     registration statement under the Act and applicable state securities laws
     relating to such security, unless in the opinion of counsel satisfactory to
     the Company, such registrations are not required under the Act. Each
     certificate for the Warrant, the Warrant Shares and any other security
     issued or issuable upon exercise of this Warrant shall contain a legend on
     the face thereof, in form and substance satisfactory to counsel for the
     Company, setting forth the restrictions on transfer contained in this
     Section.

          (b) The Company agrees to file a registration statement, which shall
     include the Warrant Shares, on Form SB-2 or another available form (the
     "Registration Statement"), pursuant to the Act, pursuant to a Registration
     Rights Agreement between the Company and Holder dated as of the date hereof
     (the "Registration Rights Agreement").

     8. Notices. Any notice or other communication required or permitted
hereunder shall be in writing and shall be delivered personally, telegraphed,
telexed, sent by facsimile transmission or sent by certified, registered or
express mail, postage pre-paid. Any such notice shall be deemed given when so
delivered personally, telegraphed, telexed or sent by facsimile transmission,

                          REGISTRATION RIGHTS AGREEMENT

     THIS REGISTRATION RIGHTS AGREEMENT, dated as of February 23, 2000 (this
"Agreement"), is made by and between Global MAINTECH Corporation, a Minnesota
corporation (the "Company"), and the each entity named on the signature page
hereto (individually referred to as the "Initial Investor" and collectively
referred to as the "Initial Investors").

                              W I T N E S S E T H:

     WHEREAS, upon the terms and subject to the conditions of the Securities
Purchase Agreement, dated as of February 23, 2000, between the Initial Investors
and the Company (the "Securities Purchase Agreement"; capitalized terms not
otherwise defined herein shall have the meanings ascribed to them in the
Securities Purchase Agreement), the Company has agreed to issue and sell to the
Initial Investors an aggregate of up to 2,000 shares of Series F Cumulative
Convertible Redeemable Preferred Stock, no par value, $1,000 stated value (the
"Preferred Stock," which term, as used herein shall have the meaning ascribed to
it in the Securities Purchase Agreement); and

     WHEREAS, the Company has agreed to issue the Warrants to the Initial
Investors in connection with the issuance of the Preferred Stock; and

     WHEREAS, the Preferred Stock is convertible into shares of Common Stock
(the "Conversion Shares") upon the terms and subject to the conditions contained
in the Certificate of Designation; and

     WHEREAS, the Warrants to be issued to the Initial Investors may be
exercised for the purchase of shares of Common Stock (the "Warrant Shares") upon
the terms and conditions of the Warrants; and

     WHEREAS, to induce the Initial Investors to execute and deliver the
Securities Purchase Agreement, the Company has agreed to provide certain
registration rights under the Securities Act of 1933, as amended, and the rules
and regulations thereunder, or any similar successor statute (collectively, the
"Securities Act"), with respect to the Conversion Shares and the Warrant Shares;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and the Initial
Investor hereby agree as follows:

     1. Definitions. As used in this Agreement, the following terms shall have
the following meanings:

                                       1
<PAGE>

          (a) "Investors" means the Initial Investors and any permitted
     transferee or assignee who agrees to become bound by the provisions of this
     Agreement in accordance with Section 9 hereof.

          (b) "Potential Material Event" means any of the following: (i) the
     possession by the Company of material information not ripe for disclosure
     in a registration statement, which shall be evidenced by determinations in
     good faith by the Board of Directors of the Company that disclosure of such
     information in the registration statement would be detrimental to the
     business and affairs of the Company; or (ii) any material engagement or
     activity by the Company which would, in the good faith determination of the
     Board of Directors of the Company, be adversely affected by disclosure in a
     registration statement at such time, which determination shall be
     accompanied by a good faith determination by the Board of Directors of the
     Company that the registration statement would be materially misleading
     absent the inclusion of such information.

          (c) "Register," "Registered," and "Registration" refer to a
     registration effected by preparing and filing a Registration Statement or
     Statements in compliance with the Securities Act and pursuant to Rule 415
     under the Securities Act or any successor rule providing for offering
     securities on a continuous basis ("Rule 415"), and the declaration or
     ordering of effectiveness of such Registration Statement by the United
     States Securities and Exchange Commission (the "SEC").

          (d) "Registrable Securities" means the Conversion Shares and the
     Warrant Shares.

          (e) "Registration Statement" means a registration statement of the
     Company under the Securities Act.

     2. Registration.

          (a) Mandatory Registration. The Company shall prepare and file with
     the SEC, as soon as possible after the Closing Date, but no later than
     forty-five (45) days following the Closing Date, a Registration Statement
     on Form SB-2, registering for resale by the Investors all of the
     Registrable Securities, but in no event more than two hundred percent
     (200%) of the aggregate number of shares into (i) which the Preferred Stock
     would be convertible at the time of filing of the Registration Statement
     (assuming for such purposes that all shares of Preferred Stock had been
     eligible to be converted, and had been converted, into Conversion Shares in
     accordance with their terms, whether or not such eligibility or conversion
     had in fact occurred as of such date), and (ii) which would be issued upon
     exercise of all of the Warrants at the time of filing of the Registration
     Statement (assuming for such purposes that all such Warrants had been
     eligible to be exercised and had been exercised in accordance with their
     terms, whether or not such eligibility or exercise had in fact occurred as
     of such date). The Registration Statement shall also state that, in
     accordance with Rule 416 and 457 under the Securities Act, it also covers
     such indeterminate number of additional shares of Common Stock as may
     become issuable upon conversion of the Preferred Stock and the exercise of
     the Warrants (and the Existing Warrants) to prevent dilution resulting from
     stock splits, or stock dividends. The Company will use its best efforts to
     cause the Registration Statement to be declared effective no later than one
     hundred twenty days (120) days after the Closing Date. If at any

                                       2
<PAGE>

     time the number of shares of Common Stock into which the Preferred Stock
     may be converted and which would be issued upon exercise of the Warrants
     equals more than seventy five percent (75%) of the aggregate number of
     shares of Common Stock then registered, the Company shall, within ten (10)
     business days after receipt of a written notice from any Investor, either
     (i) further amend the Registration Statement filed by the Company pursuant
     to the preceding sentence, if such Registration Statement has not been
     declared effective by the SEC at that time, to register up to 200% of the
     aggregate of all shares of Common Stock into which the Preferred Stock may
     then or in the future be converted and which would be issued currently or
     in the future upon exercise of the Warrants, or (ii) if such Registration
     Statement has been declared effective by the SEC at that time, file with
     the SEC an additional Registration Statement on Form SB-2, as may be
     appropriate, to register up to (A) 200% of the aggregate shares of Common
     Stock into which the unconverted Preferred Stock may then or in the future
     be converted and which would be issued currently or in the future upon
     exercise of the unexercised Warrants, less (B) the aggregate number of
     shares of Common Stock already registered which have not been issued upon
     conversions of Preferred Stock or the exercise of Warrants. The
     Registration Statement shall not include any shares other than the
     Registrable Securities, and certain other shares that the Company is
     obligated to Register as set forth in Schedule 5(b), without the consent of
     the Investors.

          (b) Payments by the Company.

               (i) If the Registration Statement covering the Registrable
          Securities is not filed with the SEC on or before forty-five (45) days
          after the Closing Date (the "Required Filing Date"), then the Company
          shall pay each Investor a late filing penalty (collectively "Late
          Filing Penalties"), (i) on the first day after the Required Filing
          Date, an amount equal to two percent (2%) of the purchase price paid
          pursuant to the Securities Purchase Agreement (the "Purchase Price")
          for the Preferred Stock then held by each such Investor on such date,
          and (ii) on each subsequent monthly anniversary of the Required Filing
          Date, if the Registration Statement has not been filed in proper form
          on or before such date, an amount equal to three percent (3%) of the
          Purchase Price for the Preferred Stock held by each such Investor on
          each such subsequent monthly anniversary date.

               (ii) If the Registration Statement covering the Registrable
          Securities is not effective within the earlier of (a) five (5) days
          after notice by the SEC that it may be declared effective (including
          the issuance by the SEC of a "no review letter"), or (b) one hundred
          twenty (120) days following the Closing Date (the "Required Effective
          Date"), then the Company shall pay each Investor a late effective date
          penalty (collectively "Late Effective Date Penalties")(sometimes Late
          Filing Penalties and Late Effective Penalties are collectively
          referred to as "Late Penalties"), (i) on the first day after the
          Required Effective Date, an amount equal to three percent (2%) of the
          Purchase Price for the Preferred Stock then held by each such Investor
          on such date and (ii) on each subsequent monthly anniversary of the
          Required Effective Date, if the Registration Statement has not been
          declared effective on or before such date, an amount equal to three
          percent (3%) of the Purchase Price for the Preferred Stock held by
          each such Investor on each such subsequent monthly anniversary date.

                                       3
<PAGE>

               (iii) By way of illustration and not in limitation of the
          foregoing, assuming a Closing Date of February 3, 2000 (X) if the
          Registration Statement is timely filed but is not declared effective
          until July 15, 2000 (assuming for the purpose of this example that the
          SEC has not previously provided notice that it may be declared
          effective), the aggregate Late Effective Date Penalty will equal 5%
          percent of the Purchase Price (2% on June 4, the 120th day after the
          Closing Date, plus 3% on July 2) or (Y) if the Registration is filed
          on April 9 and is not declared effective until June 15, 2000 (assuming
          for the purpose of this example that the SEC has not previously
          provided notice that it may be declared effective), the aggregate Late
          Filing Penalty will equal 2% of the Purchase Price (2% on March 19,
          the 45th day after the Closing Date) and the aggregate Late Effective
          Date Penalty will equal 2% percent of the Purchase Price (2% on June
          4, the 120th day after the Closing Date).

               (iv) Late Penalties will be payable to the Investor by the
          Company in cash or other immediately available funds on the date such
          Late Penalty is incurred.

               (v) The parties acknowledge that the damages which may be
          incurred by the Investors if the Registration Statement is not filed
          by the Required Filing Date or if the Registration Statement has not
          been declared effective by the Required Registration Date may be
          difficult to ascertain. The parties agree that the Late Penalties
          represent a reasonable estimate on the part of the parties, as of the
          date of this Agreement, of the amount of such damages. The payment of
          the Late Penalties to the Investors shall not limit the Investors'
          other rights and remedies hereunder or under any other document
          entered into in connection herewith.

               (vi) Notwithstanding the foregoing, the amounts payable by the
          Company pursuant to this provision shall not be payable to the extent
          any delay in the effectiveness of the Registration Statement occurs
          because of an act of, or a failure to act or to act timely by the
          Investors or their counsel if the Company timely forwards to counsel
          any required documents or in the event all of the Registrable
          Securities may be sold pursuant to Rule 144 or another available
          exemption under the Act.

     3. Obligations of the Company. In connection with the registration of the
Registrable Securities, the Company shall do each of the following.

          (a) Prepare promptly, and file with the SEC by the Required Filing
     Date, the Registration Statement with respect to not less than the number
     of Registrable Securities provided in Section 2(a) above, and thereafter
     use its reasonable best efforts to cause each Registration Statement
     relating to Registrable Securities to become effective by the Required
     Effective Date and keep the Registration Statement effective at all times
     until the earliest (the "Registration Period") of (i) the date that is two
     (2) years after the Closing Date, (ii) the date when the Investors may sell
     all Registrable Securities under Rule 144 or (iii) the date the Investors
     no longer own any of the Registrable Securities, which Registration
     Statement (including any amendments or supplements thereto and prospectuses
     contained therein) shall not contain any untrue statement of a material
     fact or omit to state 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;

                                       4
<PAGE>

          (b) Prepare and file with the SEC such amendments (including
     post-effective amendments) and supplements to the Registration Statement
     and the prospectus used in connection with the Registration Statement as
     may be necessary to keep the Registration effective at all times during the
     Registration Period, and, during the Registration Period, comply with the
     provisions of the Securities Act with respect to the disposition of all
     Registrable Securities of the Company covered by the Registration Statement
     until such time as all of such Registrable Securities have been disposed of
     in accordance with the intended methods of disposition by the seller or
     sellers thereof as set forth in the Registration Statement;

          (c) The Company shall permit a single firm or counsel designated by
     the Investors to review the Registration Statement and all amendments and
     supplements thereto a reasonable period of time (but not less than three
     (3) business days) prior to their filing with the SEC, and not file any
     document in a form to which such counsel reasonably objects.

          (d) Notify the Investors, their counsel and managing underwriters, if
     any, immediately (and, in the case of (i)(A) below, not less than five (5)
     days prior to such filing) and (if requested by any such Person) confirm
     such notice in writing no later than one (1) Business Day following the day
     (i)(A) when a Prospectus or any Prospectus supplement or post-effective
     amendment to the Registration Statement is proposed to be filed; (B)
     whenever the Commission notifies the Company whether there will be a
     "review" of such Registration Statement; (C) whenever the Company receives
     (or representatives of the Company receive on its behalf) any oral or
     written comments from the Commission in respect of a Registration Statement
     (copies or, in the case of oral comments, summaries of such comments shall
     be promptly furnished by the Company to the Investors); and (D) with
     respect to the Registration Statement or any post-effective amendment, when
     the same has become effective; (ii) of any request by the Commission or any
     other Federal or state governmental authority for amendments or supplements
     to the Registration Statement or Prospectus or for additional information;
     (iii) of the issuance by the Commission of any stop order suspending the
     effectiveness of the Registration Statement covering any or all of the
     Registrable Securities or the initiation of any Proceedings for that
     purpose; (iv) if at any time any of the representations or warranties of
     the Company contained in any agreement (including any underwriting
     agreement) contemplated hereby ceases to be true and correct in all
     material respects; (v) of the receipt by the Company of any notification
     with respect to the suspension of the qualification or exemption from
     qualification of any of the Registrable Securities for sale in any
     jurisdiction, or the initiation or threatening of any Proceeding for such
     purpose; and (vi) of the occurrence of any event that to the best knowledge
     of the Company makes any statement made in the Registration Statement or
     Prospectus or any document incorporated or deemed to be incorporated
     therein by reference untrue in any material respect or that requires any
     revisions to the Registration Statement, Prospectus or other documents so
     that, in the case of the Registration Statement or the Prospectus, as the
     case may be, it will not contain any untrue statement of a material fact or
     omit to state any material fact required to be stated therein or necessary
     to make the statements therein, in light of the circumstances under which
     they were made, not misleading. In addition, the Company shall furnish the
     Investors with copies of all intended written responses to the comments
     contemplated in clause (C) of this Section 3(d) not later than one (1)
     Business Day in advance of the

                                       5

     filing of such responses with the Commission so that the Investors shall
     have the opportunity to comment thereon.

          (e) Furnish to each Investor whose Registrable Securities are included
     in the Registration Statement and its legal counsel identified to the
     Company, (i) promptly after the same is prepared and publicly distributed,
     filed with the SEC, or received by the Company, one (1) copy of the
     Registration Statement, each preliminary prospectus and prospectus, and
     each amendment or supplement thereto, and (ii) such number of copies of a
     prospectus, and all amendments and supplements thereto and such other
     documents, as such Investor may reasonably request in order to facilitate
     the disposition of the Registrable Securities owned by such Investor;

          (f) As promptly as practicable after becoming aware of such event,
     notify each Investor of the happening of any event of which the Company has
     knowledge, as a result of which the prospectus included in the Registration
     Statement, as then in effect, includes an untrue statement of a material
     fact or omits to state a material fact required to be stated therein or
     necessary to make the statements therein, in light of the circumstances
     under which they were made, not misleading, and use its best efforts
     promptly to prepare a supplement or amendment to the Registration Statement
     or other appropriate filing with the SEC to correct such untrue statement
     or omission, and deliver a number of copies of such supplement or amendment
     to each Investor as such Investor may reasonably request;

          (g) As promptly as practicable after becoming aware of such event,
     notify each Investor who holds Registrable Securities being sold (or, in
     the event of an underwritten offering, the managing underwriters) of the
     issuance by the SEC of a Notice of Effectiveness or any notice of
     effectiveness or any stop order or other suspension of the effectiveness of
     the Registration Statement at the earliest possible time;

          (h) Notwithstanding the foregoing, if at any time or from time to time
     after the date of effectiveness of the Registration Statement, the Company
     notifies the Investors in writing of the existence of a Potential Material
     Event, the Investors shall not offer or sell any Registrable Securities, or
     engage in any other transaction involving or relating to the Registrable
     Securities, from the time of the giving of notice with respect to a
     Potential Material Event until such Investor receives written notice from
     the Company that such Potential Material Event either has been disclosed to
     the public or no longer constitutes a Potential Material Event; provided,
     however, that the Company may not so suspend the right to such holders of
     Registrable Securities for more than two twenty (20) day periods in the
     aggregate during any 12-month period ("Suspension Period") with at least a
     ten (10) business day interval between such periods, during the periods the
     Registration Statement is required to be in effect;

          (i) Use its reasonable efforts to secure or maintain, as applicable,
     NASDAQ/OTC Bulletin Board authorization and quotation for such Registrable
     Securities and, without limiting the generality of the foregoing, to
     arrange for at least two market makers to register with the National
     Association of Securities Dealers, Inc. ("NASD") as such with respect to
     such Registrable Securities;

                                       6
<PAGE>

          (j) Provide a transfer agent and registrar, which may be a single
     entity, for the Registrable Securities not later than the effective date of
     the Registration Statement;

          (k) Cooperate with the Investors who hold Registrable Securities (or,
     subject to receipt by the Company of appropriate notice and documentation,
     as may be required by the Securities Purchase Agreement, the Certificate of
     Designations, the Warrants or this Agreement, securities convertible into
     Registrable Securities) being offered to facilitate the timely preparation
     and delivery of certificates for the Registrable Securities to be offered
     pursuant to the Registration Statement and enable such certificates for the
     Registrable Securities to be in such denominations or amounts as the case
     may be, as the Investors may reasonably request, and, within five (5)
     business days after a Registration Statement which includes Registrable
     Securities is ordered effective by the SEC, the Company shall deliver, and
     shall cause legal counsel selected by the Company to deliver, to the
     transfer agent for the Registrable Securities (with copies to the Investors
     whose Registrable Securities or securities convertible into Registrable
     Securities are included in such Registration Statement) an appropriate
     instruction and opinion of such counsel; provided, however, that nothing in
     this subparagraph (k) shall be deemed to waive any of the provisions
     regarding the conditions or method of conversion of Preferred Stock or
     exercise of Warrants into Registrable Securities; and

          (l) Take all other reasonable actions necessary to expedite and
     facilitate disposition by the Investor of the Registrable Securities
     pursuant to the Registration Statement.

     4. Obligations of the Investors. In connection with the registration of the
Registrable Securities, each Investor shall have the following obligations:

          (a) As a condition precedent to the obligations of the Company to
     complete the registration pursuant to this Agreement with respect to the
     Registrable Securities of a particular Investor, such Investor shall
     furnish to the Company such information regarding itself, the Registrable
     Securities held by it, and the intended method of disposition of the
     Registrable Securities held by it, as shall be reasonably required to
     effect the registration of such Registrable Securities and shall execute
     such documents in connection with such registration as the Company may
     reasonably request. At least five (5) days prior to the first anticipated
     filing date of the Registration Statement, the Company shall notify each
     Investor of the information the Company requires from each such Investor
     (the "Requested Information") if such Investor elects to have any of such
     Investor's Registrable Securities included in the Registration Statement.
     If at least two (2) business days prior to the filing date the Company has
     not received the Requested Information from an Investor (a "Non-Responsive
     Investor"), then the Company may file the Registration Statement without
     including Registrable Securities of such Non-Responsive Investor;

          (b) To cooperate with the Company as reasonably requested by the
     Company in connection with the preparation and filing of the Registration
     Statement hereunder, unless such Investor has notified the Company in
     writing of such Investor's election to exclude all of such Investor's
     Registrable Securities from the Registration Statement; and

                                       7
<PAGE>

          (c) Upon receipt of any notice from the Company of the happening of
     any event of the kind described in Section 3(e) or 3(f), above, such
     Investor shall immediately discontinue disposition of Registrable
     Securities pursuant to the Registration Statement covering such Registrable
     Securities until such Investor's receipt of the copies of the supplemented
     or amended prospectus contemplated by Section 3(e) or 3(f) and, if so
     directed by the Company, such Investor shall deliver to the Company (at the
     expense of the Company) or destroy (and deliver to the Company a
     certificate of destruction) all copies in such Investor's possession, of
     the prospectus covering such Registrable Securities current at the time of
     receipt of such notice.

     5. Expenses of Registration. (a) All reasonable expenses (other than
underwriting discounts and commissions of each Investor and legal fees of
counsel to each Investor) incurred in connection with registrations, filings or
qualifications pursuant to Section 3, including, without limitation, all
registration, listing, and qualifications fees, printers and accounting fees,
the fees and disbursements of counsel for the Company, and a fee for a single
counsel for the Investors not exceeding $3,500, shall be borne by the Company.

          (b) Except as and to the extent specifically set forth in Schedule
     5(b) attached hereto, neither the Company nor any of its subsidiaries has,
     as of the date hereof, nor shall the Company nor any of its subsidiaries,
     on or after the date of this Agreement, enter into any agreement with
     respect to its securities that is inconsistent with the rights granted to
     the Investors herein or otherwise conflicts with the provisions hereof.
     Except as and to the extent specifically set forth in Schedule 5(b)
     attached hereto, neither the Company nor any of its subsidiaries has
     previously entered into any agreement granting any registration rights with
     respect to any of its securities to any person or entity. Without limiting
     the generality of the foregoing, without the written consent of the
     Investors of a majority of the then outstanding Registrable Securities, the
     Company shall not grant to any person the right to request the Company to
     register any securities of the Company under the Securities Act unless the
     rights so granted are subject in all respects to the prior rights in full
     of the Investors set forth herein, and are not otherwise in conflict or
     inconsistent with the provisions of this Agreement.

     6. Indemnification. In the event any Registrable Securities are included in
a Registration Statement under this Agreement:

          (a) To the extent permitted by law, the Company will indemnify and
     hold harmless each Investor who holds such Registrable Securities, the
     directors, if any, of such Investor, the officers, if any, of such
     Investor, each person, if any, who controls any Investor within the meaning
     of the Securities Act or the Securities Exchange Act of 1934, as amended
     (the "Exchange Act") (each, an "Indemnified Person" or "Indemnified
     Party"), against any losses, claims, damages, liabilities or expenses
     (joint or several) incurred (collectively, "Claims") to which any of them
     may become subject under the Securities Act, the Exchange Act or otherwise,
     insofar as such Claims (or actions or proceedings, whether commenced or
     threatened, in respect thereof) arise out of or are based upon any of the
     following statements, omissions or violations in the Registration
     Statement, or any post-effective amendment thereof, or any prospectus
     included therein: (i) any untrue statement or alleged untrue statement of a
     material fact contained in the Registration Statement or any post-

                                       8
<PAGE>

     effective amendment thereof or the omission or alleged omission to state
     therein a material fact required to be stated therein or necessary to make
     the statements therein not misleading, (ii) any untrue statement or alleged
     untrue statement of a material fact contained in the final prospectus (as
     amended or supplemented, if the Company files any amendment thereof or
     supplement thereto with the SEC) or the omission or alleged omission to
     state therein any material fact necessary to make the statements made
     therein, in light of the circumstances under which the statements therein
     were made, not misleading or (iii) any violation or alleged violation by
     the Company of the Securities Act, the Exchange Act, any state securities
     law or any rule or regulation under the Securities Act, the Exchange Act or
     any state securities law (the matters in the foregoing clauses (i) through
     (iii) being, collectively, "Violations"). Subject to clause (b) of this
     Section 6, the Company shall reimburse the Investors, promptly as such
     expenses are incurred and are due and payable, for any legal fees or other
     reasonable expenses incurred by them in connection with investigating or
     defending any such Claim. Notwithstanding anything to the contrary
     contained herein, the indemnification agreement contained in this Section
     6(a) shall not (I) apply to a Claim arising out of or based upon a
     Violation which occurs in reliance upon and in conformity with information
     furnished in writing to the Company by or on behalf of any Indemnified
     Person expressly for use in connection with the preparation of the
     Registration Statement or any such amendment thereof or supplement thereto,
     if such prospectus was timely made available by the Company pursuant to
     Section 3(c) hereof; (II) be available to the extent such Claim is based on
     a failure of the Investor to deliver or cause to be delivered the
     prospectus made available by the Company; or (III) apply to amounts paid in
     settlement of any Claim if such settlement is effected without the prior
     written consent of the Company, which consent shall not be unreasonably
     withheld. Each Investor will indemnify the Company and its officers,
     directors and agents against any claims arising out of or based upon a
     Violation which occurs in reliance upon and in conformity with information
     furnished in writing to the Company, by or on behalf of such Investor,
     expressly for use in connection with the preparation of the Registration
     Statement, subject to such limitations and conditions as are applicable to
     the Indemnification provided by the Company to this Section 6. Such
     indemnity shall remain in full force and effect regardless of any
     investigation made by or on behalf of the Indemnified Person and shall
     survive the transfer of the Registrable Securities by the Investors
     pursuant to Section 9.

          (b) Promptly after receipt by an Indemnified Person or Indemnified
     Party under this Section 6 of notice of the commencement of any action
     (including any governmental action), such Indemnified Person or Indemnified
     Party shall, if a Claim in respect thereof is to be made against any
     indemnifying party under this Section 6, deliver to the indemnifying party
     a written notice of the commencement thereof and the indemnifying party
     shall have the right to participate in, and, to the extent the indemnifying
     party so desires, jointly with any other indemnifying party similarly
     noticed, to assume control of the defense thereof with counsel mutually
     satisfactory to the indemnifying party and the Indemnified Person or the
     Indemnified Party, as the case may be. In case any such action is brought
     against any Indemnified Person or Indemnified Party, and it notifies the
     indemnifying party of the commencement thereof, the indemnifying party will
     be entitled to participate in, and, to the extent that it may wish, jointly
     with any other indemnifying party similarly notified, assume the defense
     thereof, subject to the provisions herein stated and after notice from the
     indemnifying party to such Indemnified Person or Indemnified Party of its
     election so to assume the defense thereof, the indemnifying party will not
     be liable to such Indemnified Person or Indemnified

                                       9
<PAGE>

     Party under this Section 6 for any reasonable legal or other reasonable
     out-of-pocket expenses subsequently incurred by such Indemnified Person or
     Indemnified Party in connection with the defense thereof other than
     reasonable costs of investigation, unless the indemnifying party shall not
     pursue the action of its final conclusion. The Indemnified Person or
     Indemnified Party shall have the right to employ separate counsel in any
     such action and to participate in the defense thereof, but the fees and
     reasonable out-of-pocket expenses of such counsel shall not be at the
     expense of the indemnifying party if the indemnifying party has assumed the
     defense of the action with counsel reasonably satisfactory to the
     Indemnified Person or Indemnified Party. The failure to deliver written
     notice to the indemnifying party within a reasonable time of the
     commencement of any such action shall not relieve such indemnifying party
     of any liability to the Indemnified Person or Indemnified Party under this
     Section 6, except to the extent that the indemnifying party is prejudiced
     in its ability to defend such action. The indemnification required by this
     Section 6 shall be made by periodic payments of the amount thereof during
     the course of the investigation or defense, as such expense, loss, damage
     or liability is incurred and is due and payable.

     7. Contribution. To the extent any indemnification by an indemnifying party
is prohibited or limited by law, the indemnifying party agrees to make the
maximum contribution with respect to any amounts for which it would otherwise be
liable under Section 6 to the fullest extent permitted by law; provided,
however, that (a) no contribution shall be made under circumstances where the
maker would not have been liable for indemnification under the fault standards
set forth in Section 6; (b) no seller of Registrable Securities guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any seller of Registrable
Securities who was not guilty of such fraudulent misrepresentation; and (c)
contribution by any seller of Registrable Securities shall be limited in amount
to the net amount of proceeds received by such seller from the sale of such
Registrable Securities.

     8. Reports under Exchange Act. With a view to making available to the
Investors the benefits of Rule 144 promulgated under the Securities Act or any
other similar rule or regulation of the SEC that may at any time permit the
Investors to sell securities of the Company to the public without registration
("Rule 144"), the Company agrees to:

          (a) make and keep public information available, as those terms are
     understood and defined in Rule 144;

          (b) use its best efforts to file with the SEC in a timely manner all
     reports and other documents required of the Company under the Securities
     Act and the Exchange Act; and

          (c) furnish to each Investor so long as such Investor owns Registrable
     Securities, promptly upon request, (i) a written statement by the Company
     that it has complied with the reporting requirements of Rule 144, the
     Securities Act and the Exchange Act, (ii) a copy of the most recent annual
     or quarterly report of the Company and such other reports and documents so
     filed by the Company and (iii) such other information as may be reasonably
     requested to permit the Investors to sell such securities pursuant to Rule
     144 without registration.

                                       10
<PAGE>

     9. Assignment of the Registration Rights. The rights to have the Company
register Registrable Securities pursuant to this Agreement shall be
automatically assigned by an Investor to any transferee of the Registrable
Securities (or all or any portion of any Preferred Stock of the Company which is
convertible into such securities) permitted or allowable by the terms of the
Securities Purchase Agreement only if: (a) such Investor agrees in writing with
the transferee or assignee to assign such rights, and a copy of such agreement
is furnished to the Company within a reasonable time after such assignment, (b)
the Company is, within a reasonable time after such transfer or assignment,
furnished with written notice of (i) the name and address of such transferee or
assignee and (ii) the securities with respect to which such registration rights
are being transferred or assigned, (c) immediately following such transfer or
assignment the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act and applicable state securities
laws, and (d) at or before the time the Company received the written notice
contemplated by clause (b) of this sentence the transferee or assignee agrees in
writing with or in favor of the Company to be bound by all of the provisions
contained herein, a copy of which shall be provided to the Company. The copies
referred to in clauses (a) and (d) of the immediately preceding sentence may be
redacted to delete certain financial and other details of the transaction
between the Investor and its transferee if the same is included in the document
to be provided to the Company. In the event of any delay in filing or
effectiveness of the Registration Statement as a result of such assignment, the
Company shall not be liable for any damages arising from such delay, or the
payments set forth in Section 2(c) hereof.

     10. Amendment of Registration Rights. Any provision of each such Agreement
may be amended and the observance thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Company and Investors who hold collectively eighty (80%)
percent of the Preferred Shares. Any amendment or waiver effected in accordance
with this Section 10 shall be binding upon each Investor and the Company.

     11. Miscellaneous.

          (a) A person or entity is deemed to be a holder of Registrable
     Securities whenever such person or entity owns of record such Registrable
     Securities. If the Company receives conflicting instructions, notices or
     elections from two or more persons or entities with respect to the same
     Registrable Securities, the Company shall act upon the basis of
     instructions, notice or election received from the registered owner of such
     Registrable Securities.

          (b) Any notice or communication required or permitted by this
     Agreement shall be given in writing addressed as follows:

     Agreement or otherwise, or delay by a party in exercising such right or
     remedy, shall not operate as a waiver thereof.

          (d) This Agreement shall be governed by and interpreted in accordance
     with the laws of the State of Minnesota for contracts to be wholly
     performed in such state and without giving effect to the principles thereof
     regarding the conflict of laws. Any litigation based thereon, or arising

     of the Company or Purchaser shall be brought and maintained exclusively in
     the state or Federal courts of the State of Minnesota, sitting in
     Minneapolis. The Company hereby expressly and irrevocably submits to the

     of execution or otherwise) with respect to itself or its property, the
     Company hereby irrevocably waives such immunity in respect of its
     obligations under this Agreement and the related agreements entered into in
     connection herewith.

          (e) If any provision of this Agreement shall be invalid or
     unenforceable in any jurisdiction, such invalidity or unenforceability

     Agreement or the validity or enforceability of this Agreement in any other
     jurisdiction.

          (f) Subject to the requirements of Section 9 hereof, this Agreement

     only and shall not limit or otherwise affect the meaning thereof.

     perform its obligations under Section 3(a) hereof, or any delay in such
     performance could result in loss to the Investors, and the Company agrees
     that, in addition to any other liability the Company may have by reason of
     such failure or delay, the Company shall be liable for all direct damages
     caused by any such failure or delay, unless the same is the result of force
