<PAGE>

       2.4 Purchase Price Adjustment. The Purchase Price described in Section
2.3 above shall be increased or reduced (the "Purchase Price Adjustment") if the
difference between the Recent Statement of Selected Assets and Liabilities and
the Closing Date Statement of Selected Assets and Liabilities is greater than
$200,000, which increase or reduction, if any, shall be determined based on the
following procedure:

              (a) Within twenty (20) days after Closing, Seller shall prepare
and deliver to Buyer a list of Inventory and Accrued Expenses as of the Closing
Date, valued on the same basis and using the same methods and procedures applied
on a basis consistent with the methods and procedures used to prepare the Recent
Statement of Selected Assets and Liabilities, and promptly thereafter Buyer and
Seller shall jointly conduct a review of Inventory and Accrued Expenses,
including, at the request of either party, a physical inventory count.

              (b) Buyer must, as soon as reasonably practicable after the
Closing Date but not later than twenty (20) days after receiving the Seller's
list of Inventory and Accrued Expense, prepare its proposed Closing Date
Statement of Selected Assets and Liabilities (setting forth, in reasonable
detail, Buyer's calculation as of the Closing Date of the value of the Inventory
and amount of Accrued Expense as of the Closing Date, which items shall be
valued on the same basis and using the same methods and procedures applied on a
basis consistent with the methods and procedures used to prepare the Recent
Statement of Selected Assets and Liabilities) (the "Closing Statement").

              (c) Within twenty (20) days after receipt of the Closing
Statement, Seller must give Buyer written notice of any exceptions to Buyer's
calculation of the Closing Date Statement of Selected Assets and Liabilities.

                     (i) If Seller has not given Buyer such written notice
              within that twenty-day period, then the values set forth in the
              Closing Statement will be conclusive and binding on the parties.

                     (ii) If Seller gives Buyer such written notice within that
              twenty-day period, then Buyer and Seller shall promptly endeavor
              to resolve any disputes. If Seller and Buyer fail to reach an
              agreement with respect to such matters on or before twenty (20)
              days after Seller has delivered written notice to Buyer of
              exceptions to the Closing Statement, then, as to such matters
              remaining in dispute, the Seller and the Buyer shall promptly
              retain an accounting firm ("Firm") acceptable to Buyer and Seller,
              which has not rendered accounts or other services to either Buyer
              or Seller for at least three years. The Firm shall be instructed
              to apply the same methods, policies and procedures as were applied
              in preparing the Recent Statement of Selected Assets and
              Liabilities. Subject to the foregoing, the Firm shall make an
              independent determination of any matters in dispute and deliver an
              opinion to Buyer and Seller within 45 days of the Firm's
              retention, which determination will be conclusive and binding on
              the parties. All fees and expenses of the Firm must be paid by the
              party to this Agreement not generally prevailing on the issues as
              determined by the Firm, except that if the Firm determines that
              neither party could fairly found to be the prevailing party, then
              such fees and expenses of the Firm shall be paid equally by Buyer
              and Seller.

                                       6

       2.5 Payment of Purchase Price Adjustment.

              (a) If the net amount indicated on the Recent Statement of
Selected Assets and Liabilities is $200,000 or less than the amount indicated on
the Closing Date Statement of Selected Assets and Liabilities, then Buyer shall
pay the difference between the Closing Date Statement of Selected Assets and
Liabilities and the Recent Statement of Selected Assets and Liabilities to
Seller, within five (5) days after final determination of the Closing Date
Statement of Selected Assets and Liabilities, by a wire transfer of good funds
or a cashiers check.

              (b) If the net amount indicated on the Recent Statement of
Selected Assets and Liabilities is $200,000 or greater than the Closing Date
Statement of Selected Assets and Liabilities, then Seller shall pay the
difference between the Closing Date Statement of Selected Assets and Liabilities
and the Recent Statement of Selected Assets and Liabilities to Buyer, within
five (5) days after final determination of the Closing Date Statement of
Selected Assets and Liabilities, by a wire transfer of good funds or a cashiers
check.

       2.6 Allocation of Purchase Price. The allocation of the Purchase Price
for tax purposes will be determined by mutual agreement of the Buyer and Seller
following the completion of the Purchase Price Adjustment described in Section
2.4 of this Agreement and upon reaching agreement of the allocation of the
Purchase Price, such agreement will be set forth in a written schedule signed by
both parties and which shall be incorporated by reference into this Agreement as
Schedule 2.6B. It is further agreed that the allocation of the consideration to
the Assets as set forth in Schedule 2.6B will be binding on Seller and Buyer for
federal and state income tax purposes and will be consistently so reflected by
Buyer and Seller on their respective federal and state income tax returns. Buyer
and Seller agree that the allocation of the Purchase Price set forth in Section
2.3, prior to any Purchase Price Adjustment, is as set forth in Schedule 2.6A.

as now conducted and to own and operate the assets and properties now owned and
operated by it; and is duly qualified to do business and is in good standing in
each jurisdiction wherein the conduct of its business or the ownership of its
assets and properties requires such qualification and the failure to be so

in the business, operations, affairs or condition of Buyer or its properties or
assets. Buyer has no knowledge of any facts or circumstances that could

the Commission, conformed in all Material respects to the requirements of the
Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder and, as of the date of such filing, such Disclosure Documents did not
contain an untrue statement of a Material fact or omit to state a Material fact

obligations with respect to Power General products sold before the Closing;

requirements. Seller will fulfill all requirements, if any, under the WARN Act
with respect to the Transition Employees and shall be responsible for any cost

failure to fulfill such requirements; provided, however, that notwithstanding
the foregoing, in the event that, at Buyer's direction, Seller separates the
employment of the Transition Employees beyond the time period specified in the
Transition Services Agreement, and such action results in the Seller incurring
obligations under the WARN Act, then Buyer shall indemnify Seller for all costs
incurred by Seller related to Seller's WARN Act obligations in accordance with
Article IX hereof.

       6.10 No Solicitation.

              (a) Seller will not, nor shall Seller authorize or permit any of

agents retained by or acting on behalf of Seller to, directly or indirectly (i)
initiate, solicit or encourage, directly or indirectly, any inquiries or the

Proposal (as hereinafter defined), (ii) except as permitted below, engage,
participate in discussions or negotiations with, or continue negotiations or
discussions with, or furnish any

                                       21
<PAGE>

information or data to, or take any other action to, facilitate any inquiries or
making any proposal by, any third party relating to an Acquisition Proposal, or
(iii) except as permitted by and pursuant to the terms and conditions in this
Agreement, enter into any agreement with respect to any Acquisition Proposal or
approve an Acquisition Proposal. Notwithstanding anything to the contrary
contained in this Section 6.10 or in any other provision of this Agreement,
prior to Closing Seller may participate in discussions or negotiations with and
furnish information to any third party making an unsolicited Acquisition
Proposal (a "Potential Acquiror") or approve an unsolicited Acquisition Proposal
if both (A) Seller's Board of Directors duly determines in good faith, that a
Potential Acquiror has submitted to Seller an Acquisition Proposal that is a
Superior Proposal (as hereinafter defined), and (B) Seller's Board of Directors
determines in good faith, after receiving advice from outside legal counsel
experienced in such matters (including Seller's counsel named in Section 11.11),
that the failure to participate in such discussions or negotiations or to
furnish such information is reasonably likely to violate the Board's fiduciary
duties under applicable law.

              (b) In the event that Seller shall receive any Acquisition
Proposal, it shall promptly (and in no event later than 24 hours after receipt
thereof) furnish to Buyer the identity of the Potential Acquiror and the terms
of such Acquisition Proposal. Seller will keep the Buyer fully informed (and
respond to Buyer's inquiries) regarding the status of negotiations concerning
any Acquisition Proposal. Copies of any information supplied to the Potential
Acquiror not previously supplied to Buyer shall be simultaneously supplied to
Buyer.

              (c) Nothing contained in this Section 6.10 shall prohibit Seller's
Board of Directors from accepting an Acquisition Proposal by a Potential
Acquiror; provided, that, if the Seller's Board determines to accept an
Acquisition Proposal, Buyer's right to terminate this Agreement (assuming no
other breach by Buyer) pursuant to paragraph (e) of Section 10.1 shall
immediately arise, with the consequences set forth in subparagraph (f) of this
Section 6.10.

              (d) For the purposes of this Agreement, the term "Acquisition
Proposal" shall mean any unsolicited, bona fide proposal made by any person or
entity other than Buyer to, directly or indirectly, purchase or otherwise
acquire beneficial ownership of all or a material portion of the assets of the
Power General Business.

              (e) For the purposes of this Agreement, the term "Superior
Proposal" means any Acquisition Proposal which has financial terms that Seller's
the Board of Directors determines, in good faith, to be more favorable to Seller
than this Agreement. The parties agree that for purposes of the preceding
sentence (but for no other purpose), an offer which is conditioned on completion
of due diligence shall be deemed to constitute a "Superior Proposal" if such
offer otherwise meets the definition of "Superior Proposal."

              (f) Notwithstanding any other provision in this Agreement to the
contrary, if this Agreement is terminated pursuant to Section 10.1(e), then
Seller shall pay to Buyer $100,000 (the "Termination Fee") in cash or by wire
transfer of immediately available funds to an account designated in writing by
Buyer, such payment to be made promptly, but in no event later than the second
(2nd) business day following such termination. Buyer acknowledges that, except
for liability that Seller might have to Buyer arising from a breach of this
Agreement due to the fraudulent or willful misconduct of Seller, the Termination
Fee, once paid as contemplated

                                       22
<PAGE>

by this Section 6.10(f), shall be the sole remedy of Buyer in the circumstances
described in this Section 6.10. Seller shall also be obligated to pay the
Termination Fee pursuant to the provisions in the last clause of Section
10.1(d). Seller acknowledges that the agreements contained in this Section
6.10(f) and Section 10.1(d) and Section 10.1(e) are an integral part of the
transactions contemplated by this Agreement, and that, without such agreements,
Buyer would not enter into this Agreement. Accordingly if Seller fails promptly
to pay the amounts due pursuant to this Section 6.10(g) or the last clause of
Section 10.1(d), (i) Seller shall pay interest on such amounts at the prime rate
announced by U.S. Bank National Association, Minneapolis office, in effect on
the date the Termination Fee was required to be made, plus two percent (2%), and
(ii) if in order to obtain such payment Buyer commences a suit or takes other
action which results in a judgment or other binding determination against Seller
for the Termination Fee, Seller shall also pay to Buyer, its costs and expenses
(including reasonable attorneys' fees) in connection with such suit, together
with interest payable under the preceding clause (i).

       6.11 Acquired Contracts. From and after the Closing Date, Buyer shall
perform its obligations under the Acquired Contracts in a manner which will not
adversely affect Seller's ability to collect its Accounts Receivable applicable
to such Acquired Contracts.

authorized and reserved for issuance, free from any preemptive rights, solely
for the purpose of effecting conversions of the shares of Preferred Stock to be
issued to Buyer hereunder, such number of its shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all of such
Preferred Stock (the "Reserved Amount"). As of the Closing Date, the Reserved
Amount shall be 488,000 shares (subject to equitable adjustment for each of the
events specified in the Certificate of Designation) of Common Stock.

       6.13 Quotation on Nasdaq. Buyer shall (i) promptly following the Closing,
take such action as may be necessary to include all of the shares of Common
Stock that constitute the Reserved Amount on the Nasdaq National Market, and
(ii) use its best efforts to maintain the designation and quotation, or listing,
of the Common Stock on the Nasdaq National Market or a national securities
exchange for a minimum of six (6) years following the Closing.

       6.14 Form 8-K Current Report. Buyer will file a Current Report on Form
8-K with the Commission following the Closing, within the time period required
by such Form, to report the transaction provided for under this Agreement.
Seller will cooperate with Buyer in preparing such financial statements for the
Power General Business as may be required to be filed by Seller as part of its
Current Report on Form 8-K to be filed with the Commission following the
Closing, and further agrees to retain its accountants, PricewaterhouseCoopers
("PWC"), to conduct such audit of the financial statements as may be required by
the Form 8-K or the Commission. Buyer and Seller shall equally share the costs
of PWC for such audit, up to $100,000, and Buyer shall be responsible for all
such costs of PWC in excess of $100,000.

prospects of the Buyer.

              (e) Opinion of Buyer's Counsel. Seller shall have received an

                                  ARTICLE VIII

                            NON-COMPETITION AGREEMENT

       8.1 Covenants of Seller. Seller shall not, for a period of two (2) years
following the Closing Date, directly or indirectly, either individually or in
partnership or in conjunction in any way with any other person or entity,
whether as principal, agent, employee, officer, consultant, shareholder,
guarantor, creditor or in any other manner whatsoever:

              (a) Competitive Business. Engage anywhere in the world, in the
business of developing, manufacturing, marketing or selling products the same as
or similar to products being manufactured by the Power General Business as of or
prior to the Closing Date (the "Competitive Business");

              (b) Employees. Offer employment to or endeavor to entice away from
the Power General Business or Buyer any Retained Employee, or interfere in any
way with the employment relationship between any such employee and the Power
General Business or Buyer, so long as such employee continues to be employed by
the Buyer or Buyer's successors or assigns; or

              (c) 5% Ownership. Notwithstanding the foregoing, nothing in this
Agreement shall prevent Seller from acquiring and holding, directly or
indirectly (and including the holdings of any other person or entity not acting
at arm's length with Seller) not more than five percent (5%) of the outstanding
equity of any entity engaged in a Competitive Business if such equity is listed
on a stock exchange, provided that no shareholder, officer or director of Seller
is a member of the Board of Directors or an officer or employee of, or
consultant to, or otherwise involved with, directly or indirectly, such entity.

       8.2 Independent Covenants. The covenants in Section 8.1 are intended to
be, and shall be, construed as separate and independent covenants for each
separate state within the United States of America, and for each foreign country
other than the United States of America. To the extent that any such covenant
shall be adjudicated to be unenforceable in any one or more states in the United
States of America, or in any county or other municipal subdivision thereof, or
in any foreign country, such adjudication shall not affect such covenant with
respect to each other state, county, country, or governmental subdivision. To
the extent that any such covenant shall be declared unenforceable beyond a time
limitation adjudicated with respect to such covenant, then such covenant shall
be limited to such time limitation, but shall be fully enforceable to the full
extent of such time limitation.

       8.3 Covenant of Buyer. Buyer shall not, for a period of two (2) years
following the Closing Date, directly or indirectly, offer employment to or
endeavor to entice away from Seller any employee of Seller other than a
Transition Employee, or interfere in any way with the employment relationship
between any such employee and Seller, so long as such employee continues to be
employed by Seller or Seller's successors or assigns.

       8.4 Remedies. The parties acknowledge and agree that a monetary remedy
for breach of any of the covenants set forth in this Article VIII would be
inadequate, and would be

                                       26
<PAGE>

impracticable and difficult to prove, and they further agree that any such
breach would cause the damaged party irrevocable harm. As a consequence, the
parties hereby acknowledge, confirm and agree that, in the event of any such
breach by a party of any covenants in this Article VIII, the damaged party shall
be entitled to temporary and permanent injunctive relief without the necessity
of proving actual damages. The parties further confirm and agree that the
damaged party shall be entitled to such relief, including temporary restraining
orders, preliminary injunctions and permanent injunctions, without the necessity
of posting a bond or making undertaking in connection therewith, and each of the
parties hereby waive any requirement for bond or undertaking. The parties
acknowledge that in the absence of such waiver, a court might require a bond or
undertaking in connection with an application for temporary or permanent
injunctive relief. The failure by a damaged party to enforce or seek to enforce
any of the covenants set forth in this Article VIII shall in no way affect or
limit its right at a future date to enforce or seek to enforce such covenants.

                                   ARTICLE IX

                         INDEMNIFICATION AND SURVIVAL OF
                         REPRESENTATIONS AND WARRANTIES

       9.1 Indemnification by Seller. Seller hereby agrees to indemnify Buyer
and its affiliates and their respective officers, directors, employees,
stockholders, agents and representatives against, and agrees to hold them
harmless from any loss, liability, claim, deficiency, damage or expense
(including reasonable legal fees and expenses), as incurred (payable quarterly
upon written request), for or on account of or arising from or in connection
with or otherwise with respect to (i) any and all liabilities and obligations of
Seller, contingent or otherwise, that are not Assumed Liabilities, including,
without limitation, all liabilities and obligations of Seller and any of
Seller's affiliates for any and all state or federal taxes payable by Seller;
and (ii) any representation or warranty of Seller contained herein not being
true and correct as of the date hereof or as of the Closing Date; or (iii)
Seller's breach of any covenant contained in this Agreement or in any agreement
related hereto.

       9.2 Indemnification by Buyer. Buyer hereby agrees to indemnify Seller and
its officers, directors, employees, stockholders, agents and representatives
against, and agrees to hold them harmless from, any loss, liability, claim,
deficiency, damage or expense (including reasonable legal fees and expenses), as
incurred (payable quarterly upon written request), for or on account of or
arising from or in connection with or otherwise with respect to (i) any and all
Assumed Liabilities, (ii) any representation or warranty of Buyer contained
herein not being true and correct as of the date hereof or as of the Closing
Date; or, (iii) Buyer's breach of any covenant contained in this Agreement or in
any agreement related hereto.

       9.3 Indemnification Procedure.

              (a) In order for a party (the "indemnified party"), to be entitled
to any indemnification provided for under this Agreement in respect of, arising
out of or involving a claim made by any Person against the indemnified party (a
"Third-Party Claim"), such indemnified party must notify the indemnifying party
in writing of the Third-Party Claim within a reasonable time after receipt by
such indemnified party of written notice of the Third-Party

                                       27
<PAGE>

Claim. Thereafter, the indemnified party shall deliver to the indemnifying
party, within a reasonable time after the indemnified party's receipt thereof,
copies of all notices and documents (including court papers) received by the
indemnified party relating to the Third-Party Claim.

              (b) If a Third-Party claim is made against an indemnified party,
the indemnifying party will be entitled to participate in the defense thereof
and, if it so chooses, to assume the defense thereof with counsel selected by
the indemnifying party; provided such counsel is not reasonably objected to by
the indemnified party. Should the indemnifying party so elect to assume the
defense of a Third-Party Claim, the indemnifying party will not be liable to the
indemnified party for any legal expenses subsequently incurred by the
indemnified party in connection with the defense thereof. If the indemnifying
party elects to assume the defense of a Third-Party Claim, the indemnified party
will (i) cooperate in all reasonable respects with the indemnifying party in
connection with such defense, (ii) not admit any liability with respect to, or
settle, compromise or discharge, any Third-Party Claim without the indemnifying
party's prior written consent and (iii) agree to any settlement, compromise or
discharge of a Third-Party Claim which the indemnifying party may recommend and
which by its terms obligates the indemnifying party to pay the full amount of
the liability in connection with such Third-Party Claim and which releases the
indemnified party completely in connection with such Third-Party Claim. In the
event the indemnifying party shall assume the defense of my Third-Party Claim,
the indemnified party shall be entitled to participate in (but not control) such
defense with its own counsel at its own expense. If the indemnifying party does
not assume the defense of any such Third-Party Claim, the indemnified party may
defend the same in such manner as it may deem appropriate, including but not
limited to settling such claim or litigation after giving notice to the
indemnifying party of such terms, and the indemnifying party will promptly
reimburse the indemnified party upon written request for all cost, expense
(including reasonable attorneys' fees), loss, liability or damage incurred and
paid by the indemnified party in connection with such claim.

       9.4 Limitations on Indemnification. Notwithstanding the foregoing: (i)
any claim for indemnification must be made on or prior to the August 31, 2003,
and (ii) no party to this Agreement shall be entitled to indemnification
pursuant to this Article IX until the aggregate amount for which indemnification
is sought exceeds $75,000 and, then, only to the extent such indemnification
exceeds such amount, and (iii) the aggregate obligations of either party under
this Article IX shall not exceed $750,000; provided, however, that the
limitations contained in the foregoing clauses (i), (ii) and (iii) shall not
apply to (A) claims based upon the Purchase Price Adjustment under Section 2.4;
or (B) claims for indemnification based on fraud or intentional
misrepresentation; (C) product liability claims and warranty claims arising from
or related to products sold by Seller and asserted against Buyer, but subject to
Buyer's obligations under Section 6.7 above; (D) representations and warranties
contained in Sections 4.1, 4.2, the first sentence of 4.6, 5.1, 5.2, 5.7, or 5.9
or Buyer's failure to pay amounts due Seller under the Lease, the MIS Services
Agreement, the Transition Services Agreement or the Preferred Stock. Seller and
Buyer each hereby acknowledge and agree that, except as set forth in the
Registration Rights Agreement, this Article IX shall be each party's sole and
exclusive remedy with respect to any loss, injury, damage or other liability
under this Agreement or the transactions contemplated hereby.

                                       28
<PAGE>

       9.5 Indemnification Obligations. The indemnification obligations of the
parties hereunder relate to indemnification for all losses, injuries, damages,
deficiencies, liabilities, obligations, costs or expenses to the respective
other party or parties hereto, regardless of whether such loss, injury, damage,
deficiency, liability, obligation, cost or expense arises from a Third-Party
Claim against such indemnitee or otherwise.

       9.6 Survival of Representation and Warranties. All representations and
warranties made herein by Seller or Buyer shall survive the execution and
delivery of this Agreement and shall remain in full force and effect until
August 31, 2003, and shall be deemed to have been relied upon by the other party
hereto, notwithstanding any investigation made by or on behalf of such party;
provided, however, that the representations and warranties set forth in Sections
4.1, 4.2 and the first sentence of Section 4.6, Sections 5.1, 5.2, 5.7 and 5.9
hereof shall survive the Closing and shall remain in full force and effect to
the extent permitted by law. All statements contained in any certificate,
instrument or other writing delivered by or on behalf of Seller of Buyer
pursuant hereto shall constitute representations and warranties of such party.

                                   ARTICLE X

                             TERMINATION AND WAIVER

       10.1 Termination. This Agreement may be terminated at any time prior to
the Closing:

              (a) by mutual consent of Buyer and Seller;

              (b) by Buyer if any of the conditions set forth in Sections 7.1
and 7.2 shall not have been satisfied in any Material respect and shall not have
been satisfied (or by its nature could not be satisfied) on or before July 31,
2002; or

              (c) by Seller if any of the conditions set forth in Sections 7.1
and 7.3 shall not have been satisfied in any Material respect and shall not have
been satisfied (or by its nature could not be satisfied) on or before July 31,
2002.

              (d) by either Seller or Buyer, if the Closing shall not have been
consummated on or before July 31, 2002, so long as such party has not breached
its obligations hereunder so as to cause a delay or lack of performance;
provided that if Seller shall terminate this Agreement pursuant to this
paragraph 7.1(d) and within one year after such termination enter into an
agreement with a person who submitted an Acquisition Proposal between the date
hereof and the date of termination hereunder, Seller shall be obligated to pay
to Buyer the Termination Fee and other amounts, if any, specified in Section
6.10(f) above.

              (e) by Seller or Buyer, if Seller enters into an agreement
(including an agreement in principle) to effect a Superior Proposal or Buyer
receives written notice of Seller's determination to do so; provided, however,
that Seller may not terminate this Agreement pursuant to this Section 10.1(e)
unless (i) Seller has delivered to Buyer a written notice of Seller's intent to
enter into such an agreement to effect such Acquisition Proposal, (ii) five (5)
business days have elapsed following delivery to Buyer of such written notice by
Seller and (iii) during such five (5) business day period, Seller has fully
cooperated with Buyer, including without limitation, informing Buyer of the
terms and conditions of the Acquisition Proposal, to

                                       29
<PAGE>

allow Buyer within such five-business-day period to propose amendments to the
terms of this Agreement to be at least as favorable as the Acquisition Proposal;
provided, further, that Seller may not terminate this Agreement pursuant to this
Section 10.1(e) unless, at the end of such five-business-day period, the Board
of Directors of Seller continues reasonably to believe that the Acquisition
Proposal constitutes a Superior Proposal, and Seller pays to Buyer the amount
specified under and in accordance with Section 6.10(f) above.

       10.2 Extension; Waiver. At any time prior to the Closing, the parties
hereto may (i) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (ii) waive any inaccuracies in the
representations and warranties contained herein or in my document delivered
pursuant hereto and (iii) waive compliance with any of the agreements or
conditions contained herein. Any agreement on the part of a party hereto to any
such extension or waiver shall be valid only if set forth in a written
instrument signed on behalf of such party.

Any party may designate any other address for notices given it under this
Agreement by written notice to the other parties given at least ten (10) days
prior to the effective date of that change.

       11.2 Interpretation. When a reference is made in this Agreement to a
Section, Schedule or Exhibit, such reference shall be to a Section, Schedule or
Exhibit of this Agreement unless otherwise indicated. The table of contents and
headings contained in this Agreement are for reference purposes only and shall
not affect in any way the meaning or interpretation of this Agreement. Whenever
the words "include", "includes" or "including" are used in this Agreement, they
shall be deemed to be followed by the words "without limitation". All accounting
terms not defined in this Agreement shall have the meanings determined by GAAP.

       11.3 Counterparts. This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when two or more counterparts have been signed by each of
the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart.

       11.4 Entire Agreement; No Third-Party Beneficiaries. This Agreement
(including the documents and instruments referred to herein) (a) constitutes the
entire agreement and supersedes all prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof
and (b) is not intended to confer upon any person other than the parties hereto
any rights or remedies hereunder.

       11.5 Governing Law. This Agreement shall be governed and construed in
accordance with the laws of the State of Minnesota without regard to the rules
or principles of any jurisdiction with respect to conflict of laws.

       11.6 Remedies Cumulative. Except as otherwise provided herein, the rights
and remedies provided herein shall be cumulative and the assertion by a party of
a right or remedy hereunder shall not preclude the assertion by such party of
any other rights or remedies against another party provided herein.

       11.7 Arbitration. Any controversy, dispute or claim arising out of or
relating to this Agreement or any other agreement delivered pursuant hereto, any
breach or alleged breach hereof, the making of this Agreement or fraud in the
inducement, the transactions contemplated hereby, any modification or extension

arbitration in Minneapolis, Minnesota, in accordance with the then current

                                       31
<PAGE>

rules of the American Arbitration Association, by three independent and
impartial arbitrators, one of whom shall be appointed by Seller, one of whom
shall be appointed by Buyer, and one of whom shall be appointed by the other two
arbitrators; provided however that if the parties shall agree at the time any
dispute hereunder arises, only one arbitrator shall be appointed. In the event
that the dispute concerns any matter involving accounting issues, at least one
of the arbitrators shall be a mutually agreed upon independent certified public
accountant. Notwithstanding anything to the contrary provided in this Agreement,
the arbitration shall be governed by the United States Arbitration Act, 9 U.S.C.
ss. 1 et seq. The decision of the arbitrators shall be binding on the parties,
and judgment upon the award may be entered in any court having jurisdiction
thereof. Notwithstanding anything to the contrary provided in this Section 11.7
and without prejudice to the above procedures, any party may apply to any court
of competent jurisdiction for temporary injunctive or other provisional judicial
relief if in such party's sole judgment such action is necessary to avoid
irreparable damage or to preserve the status quo until such time as the
arbitration award is rendered or the controversy is otherwise resolved.

       11.8 Confidentiality of Negotiations. The parties shall not disclose the
transactions contemplated by this Agreement or issue any press release or make
any public or general statements with respect to the transaction except as may
be mutually agreed to or required by law. If this Agreement terminates, no party
hereto shall disclose the existence of the negotiations pursuant hereto, except
as may be required by law.

       11.9 Assignment. Neither this Agreement nor any of the rights, interests
or obligations hereunder shall be assigned by any of the parties hereto without
the prior written consent of the other parties, except that Buyer may assign, in
its sole discretion, any or all of its rights, interests and obligations
hereunder to any direct or indirect wholly owned subsidiary of Buyer, provided
that Buyer shall not be released from any of its obligations hereunder by reason
of such assignment. Subject to the preceding sentence, this Agreement will be
binding upon, inure to the benefit of and be enforceable by the parties and
their respective successors and assigns.

       11.10 Expenses. Buyer and Seller will each bear their respective costs
and expenses incurred in connection with the transaction contemplated by this
Agreement, including the fees and disbursements of all attorneys, accountants,
appraisers and advisors retained by or representing them in connection with the
transaction. It is the understanding of the parties that, except for Harris
Williams & Co., whose fees shall be the sole responsibility of Seller, there are
no brokers who will be entitled to receive any commissions with respect to the
transactions contemplated by this Agreement.
