         (a)  ORGANIZATION.  The Corporation is a Minnesota corporation duly

         own its

<PAGE>

         properties and to carry on its business as now owned and operated by
         it. The Corporation is now, and has been at all times since its
         creation, duly authorized, qualified and licensed to carry on its
         business in the places and in the manner as conducted at the time
         such businesses were conducted. The Corporation is duly qualified to
         do business as a foreign corporation and in good standing in all
         jurisdictions in which it leases real property or in which the
         conduct of its business requires such qualification, except where
         failure to be so qualified would not have a material adverse effect
         on its business.

         (b)  CAPITAL.  The authorized capital stock of the Corporation consists
         of one million (1,000,000) shares of common stock, having a par value
         of One Cent ($.01) per share, of which twenty-five thousand (25,000)
         shares are issued and outstanding. All of the shares are validly
         issued, fully paid, and nonassessable. No subscriptions, options,
         rights, warrants, convertible securities, or other agreements or
         commitments of any kind exist which obligate the Corporation to issue
         or transfer from treasury any of its authorized by unissued capital
         stock.

         (c)  TITLE.  Medical is the owner, beneficially and of record, of
         all the Shares free and clear of all liens, encumbrances, security
         agreements, equities, options, claims, charges, and restrictions.

         (d)  SUBSIDIARIES.  The Corporation does not own, directly or
         indirectly, any interest or investment (whether equity or debt) in
         any corporation, limited liability company, partnership, business,
         trust, or other entity.

         Date, no items have been pledged as collateral or are held by the
         Corporation on consignment from others. The Inventories are based upon
         quantities determined by physical count or measurement, taken within

         Corporation in connection with its business (except inventories of
         raw materials, work in process, and finished goods). As of the
         Closing Date, the Corporation has good title to the properties and
         assets used by it and all such properties and assets are free and
         clear of all security interest, liens or other claims. The property
         listed on SCHEDULE 3(k) constitutes all such tangible personal
         property necessary for the conduct by the Corporation of its
         business as now conducted. Except as provided on SCHEDULE 3(k), no
         personal property used by the Corporation in connection

         now infringing, on any trade name, trademark, service mark, or
         copyright belonging to any other person, firm, or corporation. The
         Corporation owns adequate licenses or other rights to use all
         trademarks, service marks, trade names, and copyrights necessary for
         its business as now conducted by it, and that ownership or use does

         any interference actions or other judicial, arbitration, or other
         adversary proceedings concerning the patents or applications for

         person, firm, or corporation.

         correct copies of all licenses in which the Corporation is a party.

         trade secret, or formula. The Corporation has the right and

         designs, and formulas as are necessary to enable it to conduct and
         to continue to conduct all phases of its business in the manner
         presently conducted by it, and that use, to the best of the
         Corporation's knowledge, does not, and will not, conflict with,
         infringe on, or violate any patent or other right of others.

         (p)  NAME.  Medical represents, warrants, and covenants that it has
         granted to the Corporation the right, in perpetuity, to use the name
         "Oxboro Outdoors" as part of the Corporation's name for and in
         connection with all business of whatever kind and character conducted
         previously or in the future by the Corporation, and that it has not
         granted to any other person, firm, or corporation the right to use its
         name as part of the corporate or firm name of any other such firm,
         corporation, or business.

         (q)  TITLE TO ASSETS.  The Corporation has good and marketable title to
         all its assets and interests in assets, whether real, personal, mixed,
         tangible, or intangible, which constitute all of the assets and
         interests in assets used in the business of the Corporation. Except as
         provided on SCHEDULE 3(o), all of these assets are free and clear of
         restrictions on or conditions to transfer or assignment, and free and

                   substantial amounts and do not materially detract from
                   or interfere with the present or intended use of any of
                   these assets, or materially impair business operations.

         The tangible personal property of the Corporation is generally in good
         operating condition and repair, ordinary wear and tear excepted. The
         Corporation is in possession of all premises leased to and from others.

         by or leased to the Corporation or any copyrights, patents, trademarks,
         trade names, or trade secrets licensed by the Corporation. To the best

         property bound by, any distributors' or manufacturers' representative
         or agency agreement, any output or requirements agreements, any
         agreement not entered into in the ordinary course of business, any
         indenture, mortgage, deed of trust, lease, or any agreement that is
         unusual in nature, duration, or amount. To the best of the
         Corporation's knowledge, there is no default or event that with notice
         or lapse of time, or both, would constitute a default by any party to
         any of these agreements. The Corporation has not received notice that
         any party to any of these agreements intends to cancel or terminate any
         of these agreements or to exercise or not exercise any options under
         any of these agreements. The Corporation is not a party to, nor is the
         Corporation or its properties bound by, any agreement that is
         materially adverse to the business, properties, or financial condition
         of the Corporation.

         (w)  COMPLIANCE WITH LAWS.  To the best of the Corporation's knowledge,
         the Corporation has complied with all, and is not in violation of any,
         applicable federal, state, or local statutes, laws, and regulations
         (including, without limitation, any applicable building, zoning, or
         other law, ordinance, or regulation) affecting its property or the
         operation of its business.

         (x)  LITIGATION.  Except as provided on SCHEDULE 3(x), there is no
         suit, action, arbitration, or legal, administrative, or other
         proceeding, or governmental investigation pending or, to the best
         knowledge and belief of Medical, threatened against or affecting the
         Corporation, or any of its businesses, assets, or financial
         condition. The matters set forth in SCHEDULE 3(x), if decided
         adversely to the Corporation, will not result in a material adverse
         change in the business, assets, or financial condition of the
         Corporation. The Corporation is not in default with respect to any
         order, writ, injunction, or decree of any federal, state, local, or
         foreign court, department, agency, or instrumentality. The
         Corporation is not presently engaged in any legal action to recover
         monies due either of them or damages sustained by either of them
         with respect to the business of the Corporation.

         (y)  NO BREACH OR VIOLATION.  The consummation of the transactions
         contemplated by this Agreement will not result in or constitute any
         of the following:

              (1)  A breach of any term or provision of this Agreement;

<PAGE>

              (2)  A default or an event that, with notice or lapse of time
                   or both, would be a default, breach, or violation of the
                   Articles of Incorporation or Bylaws of the Corporation or
                   any lease, license, promissory note, conditional sales
                   contract, commitment, indenture, mortgage, deed of trust,
                   or other agreement, instrument, or arrangement to which
                   Medical or the Corporation, or their property, is bound;

              (3)  An event that would permit any party to terminate any
                   agreement (except as provided on SCHEDULE 3(o)) or to
                   accelerate any maturity of any indebtedness or other
                   obligation of the Corporation; or

         Medical is necessary. The execution and delivery of this Agreement by
         Medical, and the performance of its obligations hereunder, has been
         duly authorized by its Board of Directors.

         (aa) INTEREST IN CUSTOMERS, SUPPLIERS AND COMPETITORS.  Except as

         or employee of the Corporation, nor any spouse or child of any of them,
         has any direct or indirect controlling interest in any competitor,
         supplier, or customer of the Corporation or in any person from whom or
         to whom the Corporation leases any real or personal property, or in any
         other person with whom the corporation is doing business.

         (bb) CORPORATE DOCUMENTS.  The Corporation has furnished to the
         Buyers for their examination the following:

          and addresses of all banks or other financial institutions in which
          the Corporation has an account, deposit, or safe deposit box, with
          the names of all persons authorized to draw on these accounts or
          deposits or to these boxes.

          (ee) FULL DISCLOSURE.  None of the representations and warranties
          made by Medical herein or made in any written certificate or
          memorandum furnished (or to be furnished) by Medical (or on its
          behalf), contains or will contain any untrue statement of material
          fact, or omit any material fact the omission of which would be
          misleading.

          (ff) INTERCOMPANY LOAN.  Medical acknowledges, agrees and
          represents that any amounts due to Medical from the Corporation
          including, but not limited to, the intercompany loan listed in the

          Five Thousand Dollars ($5,000)) have been converted to equity of
          the Corporation. Furthermore, such amount is not a liability or
          obligation of the Corporation and neither the Corporation nor the
          Buyers shall have any responsibility or liability to pay such
          amount to Medical.

          (gg) SURVIVAL.  Regardless of any investigation made by the Buyers
          or their representatives, or any knowledge which they may have that
          any such representation or warranty is or may be untrue or
          incorrect, the representations and warranties made in this Section
          3 shall be true and accurate in all respects as of the Closing Date
          and shall survive the Closing of this Agreement, for a period of
          two (2) years after the Closing Date, except that Medical's
          representations and warranties set forth in Sections 3(a), (b),
          (c), (d), (h), (u) and (z) shall survive forever.

          whole or in part without prior notice provided, however, that no
          such waiver of a condition shall constitute a


<PAGE>

          waiver by the Buyers of any of their other rights or remedies at

          representations, warranties, or covenants under this Agreement.

          taken with respect to these resignations that the Buyers may
          reasonably request.

          5.)  CONDITIONS PRECEDENT TO PERFORMANCE OF THE BUYERS.  The
obligations of Medical and the Corporation to sell and transfer the Shares

          9.)  MEDICAL'S POST-CLOSING OBLIGATIONS.

          (a)  MEDICAL'S INDEMNIFICATION.  Medical agrees, for a period of
          two (2) years after the Closing Date, to indemnify, defend, and
          hold the Buyers and the Corporation harmless from and against and
          in respect of any and all claims, demands, losses, costs, expenses,
          obligations, liabilities, damages, recoveries, and deficiencies,
          including interest, penalties, and reasonable attorneys' fees the
          Buyers or the Corporation may incur or suffer, which arise, result
          from, or relate to any breach of, or failure by Medical to perform,
          any of its representations, warranties, covenants, or agreements in
          this Agreement or any schedule, certificate, exhibit, or other
          instrument furnished or to be furnished by Medical under this
          Agreement provided, however, the maximum total dollar amount that
          the Sellers shall be required to indemnify the Buyers or the
          Corporation hereunder shall be limited to the amount paid for the
          Shares pursuant to Section 2. Notwithstanding the foregoing, there
          shall be no indemnification limitation pursuant to Sections 3(h)
          and (x).

          (b)  SET-OFF.  In addition to the obligation to indemnify the
          Buyers and the Corporation as set forth in Section 9(a), and
          without prejudicing the Buyers' or the Corporation's other
          remedies, the Buyers shall be entitled to offset and withhold the
          following amounts against any part of the obligation owed to the
          Medical pursuant to the Promissory Note:

               (1)  In the event that any of the fourteen (14) entities or
                    persons listed below refuses, in writing and during the
                    term of the Promissory Note, to the continuation of the
                    license they have entered into with the Corporation, the
                    amount due and payable pursuant to the terms of the
                    Promissory Note shall be reduced by Ten Thousand Dollars

                    Bobby Labonte; Tony Stewart; Ricky Rudd,; NASCAR Drivers
                    and NASCAR Logo. Notwithstanding the foregoing, if the
                    Buyers reduce the amount due under the Promissory Note
                    pursuant to this Section 9(b)(1) and the Corporation (or
                    any affiliate thereof) then enters into a like or similar
                    license with such person or entity within forty-five (45)
                    days after the reduction of the Promissory Note, such
                    amount shall be due and payable within thirty (30) days
                    thereafter.

               (2)  In the event that NFL Properties refuses, in writing and
                    during the term of the Promissory Note, to the
                    continuation of the


<PAGE>

                    license with NFL Properties (a copy of which is attached
                    hereto as SCHEDULE 9(b)) after the purchase of the Shares
                    by the Buyers, the amount due and payable pursuant to the
                    terms of the Promissory Note shall be reduced by One
                    Hundred Twenty-Five Thousand Dollars ($125,000).
                    Notwithstanding the foregoing, if the Buyers reduce the
                    amount due under the Promissory Note pursuant to this
                    Section 9(b)(2) and the Corporation (or any affiliate
                    thereof) then enters into a like or similar license with
                    the NFL Properties within forty-five (45) days after the
                    reduction of the Promissory Note, such amount shall be
                    due and payable within thirty (30) days thereafter.

          (c)  NONCOMPETITION.  Medical agrees that it shall not, for a
          period of five (5) years after Closing, directly or indirectly, for
          its own account or for the account of others, whether as principal
          or agent or through the agency of any corporation, partnership or
          other business entity, engage in the sale of licensed or unlicensed
          sports products. In the event of a violation of this Section 9(c)
          by Medical, it is agreed that the Buyers and the Corporation shall
          be entitled to money damages or injunctive relief, or both.
          Furthermore, Medical agrees to indemnify the Buyers and the
          Corporation for all costs and expenses, including reasonable
          attorneys' fees and court costs, incurred in any action brought to
          enforce this Agreement. The provisions of this Section 9 may be
          enforced by an injunction. Medical, the Buyers and the Corporation
          agree that if any claim is made by any person asserting that the
          covenant contained in this Section 9(c) is unenforceable,
          predicated upon the length of the term, geographic area, or
          otherwise, the provision or provisions upon which such
          unenforceability is predicated shall not be rendered unenforceable
          but instead shall be modified so as to be valid and fully
          enforceable for the maximum duration and geographic area (but never
          for a longer period or greater area than set forth above) that any
          court of competent jurisdiction shall find to be reasonable,
          necessary, valid and legally enforceable.

          (d)  COSTS.  If any legal action or other proceeding is brought for
          the enforcement of this Agreement, or because of an alleged
          dispute, breach, default, or misrepresentation in connection with
          any of the provisions of this Agreement, the successful or
          prevailing party or parties shall be entitled to recover reasonable
          attorneys' fees and all other costs incurred in that action or
          proceeding, in addition to any other relief to which it may be
          entitled.

          10.) TAX ELECTIONS

          (a)  SECTION 338(h)(10) ELECTION.  The purchase and sale of the
          Shares is intended to qualify as a "qualified stock purchase" under
          Section 338(d)(3) of the Internal Revenue Code and Medical, the
          Corporation and the Buyers


<PAGE>

          shall join in making a timely election under Section 338(h)(10) of
          the Internal Revenue Code and similar elections under state, local
          and foreign laws, as applicable (the "Election"). Medical and the
          Buyers acknowledge and agree that, for U.S. federal income tax
          purposes, the purchase and sale of the Shares pursuant to the
          Election will be treated as a sale of assets of the Corporation
          followed by the complete liquidation of the Company.

          (b)  PURCHASE PRICE ALLOCATION.  The Purchase Price and the
          liabilities and obligations assumed by Buyer pursuant to this
          Agreement shall be allocated among the properties and assets
          acquired by Buyer in accordance with the manner and timing
          prescribed by the Treasury Department regulations promulgated under
          Section 338 of the Internal Revenue Code and as set forth on
          SCHEDULE 10(b) attached hereto. Medical and the Buyers covenant and
          agree that such person will not take any position on any Tax
          Return, before any governmental body charged with the collection of
          any income tax or in any judicial proceeding that is in any way
          inconsistent with the provisions of this Section 10 and SCHEDULE
          10(b). Both Medical and the Buyers shall notify the other as soon
          as reasonably practicable of any audit adjustment or proposed audit
          adjustment by any governmental body that affects the allocation
          under this Section 10(b).

          11.) MISCELLANEOUS.

          (a)  ARBITRATION.  In the event there is any dispute between the
          parties hereto arising out of or relating to this Agreement and the
          parties hereto cannot resolve such dispute themselves, the parties
          hereto agree to refer and submit such dispute to the American
          Arbitration Association, Minneapolis, Minnesota (the
          "Association"), for arbitration, and any such proceeding shall be
          conducted in the Minneapolis, Minnesota metropolitan area. Any such
          arbitration shall be before a panel of three (3) arbitrators and
          shall be conducted in accordance with the rules of the Association,
          except that the parties shall be permitted discovery prior to any
          hearing in accordance with the Federal Rules of Civil Procedure,
          and the Federal Rules of Evidence and Federal Rules of Civil
          Procedure shall apply at any hearing. No arbitrator shall have any
          connection to the parties to this Agreement. The arbitrators shall
          have the right to award or include in their award any relief they
          deem proper, including without limitation, money damages, interest,
          specific performance, attorneys fees, cost and expenses incurred,
          but not exemplary or punitive damages. The award decision of the
          arbitrators shall be conclusive and binding upon all parties and
          may be entered in any court of competent jurisdiction. The parties
          agree to bring all claims in this arbitration which relate to the
          original claim. This provision shall continue after any expiration
          or termination of this Agreement.

          or commissions in the nature of finder, originator, or broker fees
          in connection

<PAGE>

          with the subject matter of this Agreement have been incurred by any
          of them. Each party to this Agreement shall indemnify the others
          and hold them harmless against any claim for brokerage or to other
          commissions from any person claiming to have worked on its behalf
          relative to the transactions contemplated by this Agreement.

          (c)  EXPENSES.  Whether or not the transactions contemplated by
          this Agreement are consummated, each of the parties hereto shall
          pay the fees and expenses of its respective counsel, accountants,
          other experts and all other expenses incurred by such party
          incidental to the negotiations, preparation, and execution of this
          Agreement.

          (d)  CAPTIONS.  Article, paragraph, or section titles or other
          headings contained in this Agreement are for convenience only and
          shall not be deemed a part of the context of this Agreement.

          (e)  ASSIGNMENT; BINDING EFFECT; AMENDMENT.  This Agreement and the
          rights hereunder may not be assigned (except by operation of law)
          and shall be binding upon and shall inure to the benefit of the
          parties hereto, the successors of the corporate parties hereto, and
          the respective heirs and legal representatives of the Shareholder.
          This Agreement, upon execution and delivery, constitutes a valid
          and binding agreement of the parties hereto enforceable in
          accordance with its terms and may be modified or amended only by a
          written instrument executed by all parties hereto.

          (f)  NO WAIVER.  No delay of, or omission in the exercise of any
          right, power or remedy accruing to any party as a result of any
          breach or default by any other party under this Agreement, shall
          impair any such right, power or remedy, nor shall it be construed
          as a waiver of or acquiescence in any such breach or default, or in
          any similar breach or default occurring later; nor shall any waiver
          of any-single breach or default be deemed a waiver of any other
          breach of default occurring before or after that waiver.

          (g)  NOTICE.  Any notice required or permitted to be given under
          this Agreement shall be sufficient if in writing and if sent by
          registered or certified mail to the parties at the addresses set
          forth below their respective names or at such other place as the

          (h)  SCHEDULES.  All documents and other papers included as a part
          of any exhibits and schedules referred to in this Agreement are
          hereby incorporated into this Agreement by reference.

          (i)  ENTIRE AGREEMENT.  This Agreement is the final, complete and
          exclusive statement and expression of the agreement among the
          parties hereto with relation to the subject matter of this
          Agreement, it being understood that there are no oral
          representations, understandings or agreements covering the same
          subject matter as this Agreement. This Agreement supersedes, and
          cannot be varied, contradicted or supplemented by evidence of any
          prior or contemporaneous discussions, correspondence, or oral or
          written agreements of any kind.

          (j)  COUNTERPARTS.  This Agreement may be executed simultaneously
          in two or more counterparts, each of which shall be deemed an
          original and all of which together shall constitute but one and the
          same instrument.

          (k)  GOVERNING LAW.  This Agreement shall be governed by and
          construed in accordance with the internal laws of the State of
          Minnesota, without giving effect to any choice or conflict of law
          provision or rule (whether of the State of Minnesota or any other
          jurisdiction) that would cause the application of the laws of any
          jurisdiction other than the State of Minnesota.

          (l)  SEVERABILITY.  In case any provision of this Agreement shall
          be invalid, illegal or unenforceable, it shall, to the extent
          possible, be modified in such manner as to be valid, legal and
          enforceable but so as most nearly to retain the intent of the
          parties. If such modification is not possible, such provision


<PAGE>

          shall be severed from this Agreement. In either case the validity,
          legality and enforceability of the remaining provisions of this
          Agreement shall not in any way be affected or impaired thereby.

          (m)  FURTHER ASSURANCES.  At any time, and from time to time before
          and after the Closing, the Buyers, the Corporation and Medical
          shall, at the request of the other party, and without additional
          consideration, execute, acknowledge, and deliver such other
          documents and instruments, and take such other actions as may be
          reasonably necessary, in order to consummate the transactions
          contemplated by this Agreement and to accomplish the purposes of
          this Agreement.

          IN WITNESS WHEREOF, the parties have duly executed this Agreement
as of the day and year first above written.
