    The Seller owns or will own on the Closing Date (hereafter
  defined) all of the issued and outstanding shares of the capital stock
  of Bayport, whether voting or non-voting, (the "Stock") and desires to
  sell all of the Stock to Buyer as hereinafter provided.  Buyer desires
  to acquire the Stock in exchange solely for the Purchase Price

    NOW, THEREFORE, in consideration of the premises and the promises

  stock (the "Purchase Price") on the Closing Date.
  
          1.2   Restrictions On Transfer Of Shares.  
  
                (a) Seller understands and agrees that the

          "The shares evidenced by this certificate have not been
  registered under the Securities Act of 1933, as amended (the "Act"), or
  any applicable state securities laws, and no transfer, sale, assignment
  or other disposition of such shares may be made except in compliance

    2.    CLOSING; TERMINATION OF AGREEMENT    
   
          (a) The closing referred to in Section 1 hereof (the
  "Closing") shall take place at the offices of Leonard, Street and
  Deinard, in Minneapolis, Minnesota on January 30, 1995, or at such other
  time and date as Buyer and Seller may in writing designate (the "Closing
  Date").  
    
   (b) This Agreement may be terminated (i) by the mutual
  written consent of Buyer and Seller, (ii) by Buyer, if there has been a
  material misrepresentation or breach of a warranty, covenant or other
  agreement by the Seller or Bayport contained herein or if any of the
  conditions precedent to Buyer's obligations hereunder shall not have
  been satisfied and not waived on or before the Closing Date, (iii) by
  the Seller if there has been a material misrepresentation or breach of a
  warranty, covenant or other agreement by Buyer contained herein or if

  shall not have been satisfied and not waived on or before the Closing
  Date.  In the event of termination, this Agreement shall be null and
  void, without further liability on the part of any party provided that
  such party has made its representations and warranties in good faith,
  used its reasonable best efforts to perform its obligations hereunder
  and in the case of the Seller, did not violate the provision contained
  in Section 5.4 hereof.  Nothing contained herein shall preclude any
  party from obtaining specific performance or any other equitable remedy
  otherwise available to it for any breach hereof. 
    
    3.    REPRESENTATIONS AND WARRANTIES OF SELLER AND BAYPORT.  In
  order to induce Buyer to enter into this Agreement and to consummate the
  transactions contemplated by this Agreement, the Seller and Bayport,
  jointly and severally, hereby make the following representations and
  warranties to Buyer, all of which are intended to survive the
  consummation of this transaction, subject to the limitations set forth
  in Section 6 of this Agreement.
    
          3.1.  Stock; Authority  
   
                (a)     All of the Stock is owned, and on the Closing
  Date will be owned, by the Seller, free and clear of all liens,
  encumbrances, claims, options, warrants, calls and commitments of every
  kind.  The Seller has full legal right, power and authority to enter
  into this Agreement and the full legal right, power and authority to
  exchange, assign and transfer the Stock to Buyer and, on the Closing
  Date, the delivery of the Stock to Buyer hereunder will transfer valid
  title thereto, free and clear of all liens, encumbrances, claims,
  options, warrants, calls and commitments of any kind.
    
   (b)    (i)   All of the Stock of Bayport is owned of
  record and beneficially by the Seller and no person or entity other than
  the Seller has the contractual power to designate any members of
  Bayport's board of directors;
    
   (ii)   The Company has no ownership interests in
  any other corporation or entity other than identified in Schedule 3.1.
    
 2

          3.2.  Existence; Good Standing; Copies Complete; Validity.
  Bayport is a corporation duly organized, validly existing and in good
  standing under the laws of the State of Minnesota. Bayport is duly
  authorized and qualified to transact business in the State of Minnesota,
  and is duly qualified to transact business and is in good standing in
  each jurisdiction in which the conduct of its business or its ownership
  or leasing of property requires such qualification, except to the extent
  that the failure to be so qualified or to be in good standing would not
  have a material adverse effect on Bayport. Copies of the charter
  documents and by-laws of Bayport, as amended to the date hereof, in each
  case certified as of the date hereof by the Secretary of Bayport have
  been delivered to Buyer.  The copies of all instruments, documents and
  certificates referenced in the schedules and which have been delivered
  to Buyer in connection with the transactions contemplated hereby are
  complete and accurate and are true and correct copies of the originals
  thereof.  This Agreement, and the agreements delivered in connection
  herewith, are the legal, valid and binding obligations of the Seller and
  Bayport, enforceable in accordance with their terms, subject to
  applicable bankruptcy, insolvency, reorganization, moratorium or similar
  laws affecting the rights of creditors generally and the availability of
  equitable remedies and defenses.  The execution, delivery and
  performance of this Agreement and the agreements delivered in connection
  herewith by the Seller and Bayport will not (i) violate or result in a
  breach of, or constitute a default under, Bayport's charter or bylaws,
  as amended, any agreement to which either is bound or any law,
  regulation, order or judgment, or (ii) create or impose any lien or
  encumbrance upon any of the assets of either the Seller or Bayport.
    
          3.3.  Outstanding Stock The authorized capital stock of
  Bayport consists solely of 1,000,000 shares of Stock, $.01 par value, of
  which 1000 shares are issued and outstanding, all of which are voting
  shares.  Each share of Stock is duly and validly authorized and issued,
  fully paid and non assessable, and to the best knowledge of Seller was
  not issued in violation of the preemptive rights of any stockholder.  No
  option, warrant, call or commitment of any kind obligating Bayport to
  issue any of its authorized but unissued capital stock or other equity
  interest exists.
    
          3.4.  Subsidiaries  Bayport has no subsidiaries and owns no
  securities (i.e., stock, warrants, calls, options, notes, bonds or other
  evidences of ownership or indebtedness) of any other person, firm or
  corporation except as set forth on Schedule 3.4.  Except as set forth on
  Schedule 3.4, no parent company or subsidiary, nor any affiliated or
  non-affiliated company, nor the Seller or any other person or entity,
  has any ownership interest, legal or equitable, in any of the assets of
  Bayport.
    
          3.5.  Financial Statements
    
   (a)    The Estimated Bayport Balance Sheet and the
  Closing Bayport Balance Sheet and notes accompanying each are
  collectively referred to as the "Financial Statements".  The Financial
  Statements will present fairly, in all material respects, the financial
  
   3
  
  position of Bayport as at their respective dates in conformity with
  generally accepted United States accounting principles, as modified, if
  at all, by the provisions of this Agreement, applied on a basis
  consistent with the accounting principles, practices and the application
  thereof heretofore followed by Bayport.  The Closing Balance Sheet will
  be accompanied by a report from Blanski Peter Kronlage & Zoch, P.A.
  which will not contain a disclaimer of opinion or a qualified or adverse
  opinion.
    
   (b)    The audited financial statements of Bayport as
  of December 31, 1993 and 1992, and for the periods then ended ("Audited
  Financial Statements"), copies of which are attached hereto as Schedule
  3.5 (b), containing balance sheets, statement of operations and related
  statement of cash flows, present fairly, in all material respects, the 
  financial condition of Bayport at December 31, 1993 and 1992, and the
  results of its operations and its cash flows for the years then ended in
  conformity with generally accepted United States accounting principles
  consistently applied throughout the periods indicated. 
    
   (c)    The unaudited financial statements of Bayport as
  at September 30, 1994, and for the period then ended ("Interim Financial
  Statements"), copies of which are attached hereto as Schedule 3.5 (c),
  containing a balance sheet, operating statement, and related supporting
  schedules, present fairly, in all material respects, the financial
  condition and results of operations of Bayport at the date and for the
  period indicated.  Except for the absence of footnotes and annual year
  end adjustments (which in the aggregate would not be material), such
  unaudited financial statements were prepared in accordance with
  generally accepted United States accounting principles consistently
  applied.
    
          3.6.  Liabilities.  Other than shown on Schedule 3.6, there
  are no material liabilities or obligations with respect to Bayport or
  its business of any nature (absolute, accrued, contingent or otherwise),
  except (i) to the extent reflected or reserved for on the Interim
  Financial Statements; (ii) liabilities or obligations arising or
  incurred in the ordinary course of business since the date of the
  Interim Financial Statements; and (iii) liabilities and obligations
  disclosed in the Schedules hereto or pursuant to or in this Agreement.
  
          3.7.  Permits, Licenses, etc. 
  
   (a)     The Seller has delivered to Buyer a list,
  summary description (Schedule 3.7 (a)) and copies, as of the date
  hereof, of all permits and permit applications, approvals, consents and
  authorizations, licenses and license applications, franchises,
  certificates, trademarks, tradenames, patents, patent applications and
  copyrights owned or held by Bayport and used in the operation of
  Bayport's business as presently conducted.  Except as disclosed in
  Schedule 3.7 (a), all of the permits, licenses, applications, franchises
  and other items set forth in Schedule 3.7 (a) are valid and in full
  force and effect and, in the reasonable judgment of the Seller, adequate
  for the operation of Bayport's business as presently conducted.  
    
 4

   (b)     All United States and foreign patents and
  pending patent applications (either granted, issued or applied for)
  licensed to, owned by or assigned to Bayport relating to or used in the
  business of Bayport are listed and briefly described in Schedule 3.7
  (b).  
    
   (c)     All United States and foreign trademarks and
  service marks (either registered or registration applied for) in which
  Bayport has any contractual or ownership interest are listed and briefly
  described in Schedule 3.7 (c).  Bayport does not currently have in
  effect any license to any third party to use any trademark, service mark
  or trade name.
    
   (d)     Except as set forth in Schedule 3.7 (d), there
  are no actions, suits, proceedings or investigations pending, or to the
  knowledge of the Seller or Bayport, threatened against, or affecting
  Bayport or its subsidiary relating to any patent, patent application,
  trade name, trade secret, trademark, trademark application, service
  mark, service mark application, copyright, process, design, computer
  program, invention, know-how or technology in any court or before or by
  any governmental agency or instrumentality, domestic or foreign, or
  before any arbitrator.  There is no pending or, to the knowledge of the
  Seller and Bayport, threatened, litigation against Bayport's making,
  using and selling all of the products which it is presently making,
  using or selling.  To the knowledge of the Seller and Bayport, Bayport's
  making, using and selling of its present products does not infringe any
  patents of others and neither the Seller nor Bayport have any knowledge
  that any other person has infringed upon or is infringing upon any
  patent or other proprietary right of Bayport.
    
          3.8.  Fixed Assets  The Seller has delivered to Buyer a list
  and summary description (Schedule 3.8), as of the date hereof, of the
  fixed assets of Bayport.  All of Bayport's fixed assets currently used
  in the business are in good working order, condition and repair, subject
  to ordinary wear and tear and normal ongoing repair and maintenance from
  time to time.  The fixed assets used by Bayport in the operation of its
  business are listed on Schedule 3.8 and are either owned by Bayport or
  leased under an agreement reflected in Schedule 3.8.  Schedule 3.8 also
  sets forth the book value of the accumulated depreciation of such fixed
  assets, determined in accordance with generally accepted United States
  accounting principles, consistently applied, as modified, if at all, by
  the provisions of this Agreement.
    
          3.9.  Leases  The Seller has delivered to Buyer a full and
  complete list (Schedule 3.9), together with true and correct copies, as
  of the date hereof, of all leases requiring payments per annum of more
  than Five Thousand Dollars ($5,000), whether or not  reflected on the
  books of Bayport as operating leases or capital leases, to which Bayport
  is a party and which relate to any property, real or personal, used by
  Bayport in the conduct of its business.
    
          3.10. Contracts and Agreements; Adverse Restrictions   
   (a)    The Seller has delivered to Buyer a full and complete
   list (Schedule 3.10), together with true and correct copies,
   as of the date hereof, of all contracts and agreements (other 
   than the leases included on Schedule 3.9) to which Bayport is
   a party or by which it or any of its property is bound and
   which provide for aggregate future payments by or to the Company 
  
 5

  (90) days' notice or less (including, without limitation,
  sales representative agreements, equipment purchase agreements,
  equipment service agreements, joint venture or partnership
  agreements, contracts with any labor organizations, loan agreements,
  bonds, mortgages, liens, pledges or other security agreements).  To the
  knowledge of the Seller and Bayport all such contracts and agreements
  included in Schedule 3.10 are in full force and effect and are binding
  upon the parties thereto and none of the parties thereto is in breach of
  any of the material provisions thereof.
    
   (b)    Except as disclosed in Schedule 3.10, Bayport is
  not a party to any contract, agreement or other commitment or instrument
  or subject to any charter or other corporate restriction or subject to
  any restriction or condition contained in any permit, license, judgment,
  order, writ, injunction, decree or award which, singly or in the
  aggregate, materially and adversely affects the business, operations,
  properties, assets or condition (financial or otherwise) of Bayport as
  currently conducted.
    
          3.11  Title and Liens
    
   (a)    Bayport has good and marketable title to all
  properties and assets owned and used in its business (the "Assets"), and
  as of the Closing Date, such Assets will be subject to no mortgage,
  lease, pledge, lien, security interest, conditional or installment sales
  agreement, encumbrance or charge, except for:
    
   (i)    those disclosed in the title report and
  UCC lien search report(s) made available to Buyer;
    
                      
                      (ii)  liens for current taxes and assessments
  that are not yet due and payable; 
    
                      
                      (iii) leases listed on Schedule 3.9;
  
                      (iv)  the rights of customers of Bayport with
  respect to inventory under orders or contracts entered into by Bayport
  in the ordinary course of business;
    
                      (v)   such imperfections or irregularities of
  title, liens, easements, charges or encumbrances as do not materially
  impair the use, occupancy or value of the Assets, or otherwise
  materially impair business operations;
  
                      (vi)  any liens disclosed in Schedule 3.11.
  
   (b)    Since December 20, 1994, there have not been
   any security interests  or any other consensual encumbrances
   of any nature imposed upon any of the Assets 

    6

   (other than those permitted pursuant to subsections (a)(i) through
   (vi) above), nor have any Uniform Commercial Code financing statements
   been executed by Bayport regarding the Assets.
    
          3.12. Insurance  The Seller has delivered to Buyer a list
  (Schedule 3.12) and has made available to Buyer copies as of the date
  hereof, of all insurance policies presently carried by Bayport.  Such
  list shall specify, for each policy, the name of the insurer, the name
  of the insured, the expiration date and whether the premiums are paid
  and current, a summary description of the property or interest insured
  and the type of risks insured, the deductible and limits of coverage,
  whether such coverage is on an occurrence or a claims made basis and the
  annual premium therefor.  Such policies are presently in full force and
  effect and shall remain in effect through the Closing Date.  For each
  insurer providing coverage for any of the insurable fixed, contingent or
  other liabilities listed in Schedule 3.12, each such insurer has been
  properly and timely notified of such matter, no reservation of rights
  letters have been received by Bayport and the insurer has assumed the
  defense of each suit or legal proceeding.
    
          3.13. Personnel  Schedule 3.13 contains a true and correct
  list of (i) all of Bayport's employees, their names, dates of birth,
  dates of hire credited by Bayport, job classifications and present
  hourly rates or salaries, (ii) all employees terminated by Bayport since
  January 1, 1994 along with the seniority of each such employee for
  recall purposes, and (iii) any affirmative action plan(s) maintained by
  Bayport and whether such plan(s) have ever been audited by the Equal
  Employment Opportunity Commission.
    
          3.14. Collective Bargaining Agreement; Benefit Plans 
    
   (a)    Other than as set forth in Schedule 3.14(a),
  Bayport has never been a party to any collective bargaining agreement.
  To the knowledge of Seller, except as set forth on Schedule 3.14 (a)
  Bayport is in compliance with all Federal, State or local laws
  respecting employment and employment practices, terms and conditions of
  employment and wages and hours, including, without limitation, all such
  laws related to union agreements, the violation of which would have a
  material adverse effect on Bayport.
    
   (b)    Bayport does not maintain or contribute to any
  employee benefit plan ("Employee Benefit Plan"), as that term is defined
  in Section 3(3) of ERISA, other than as set forth in Schedule 3.14(b). 
  Except as set forth in Schedule 3.14(b) no Employee Benefit Plan is a
  multiemployer plan as described in Section 4001(a)(3) of ERISA or a
  multiple employer plan as described in Sections 4063 and 4064 of ERISA. 
  Other than as set forth in Schedule 3.14(b), there are no employment or
  consulting agreements, severance agreements, plans or arrangements
  providing for the payment of "excess parachute payments" within the
  meaning of Section 280G of the Internal Revenue Code of 1986, as amended
  (the "Code"), employee pension or retirement plans, profit-sharing
  plans, savings plans, deferred compensation plans (either funded or
  unfunded), bonus, stock option, stock purchase, restricted stock,
  incentive, supplemental retirement, retiree medical, disability or life
  insurance plans, or any other plans, programs or arrangements providing
  similar benefits to directors, officers, employees, former employees or

  7

  retired employees of Bayport.  Schedule 3.14(b) also sets forth (i) each
  employee benefit plan for which Bayport could incur liability under
  Section 4069 of ERISA in the event such plan has been or were to be
  terminated and (ii) any plan in respect of which Bayport could incur
  liability under Section 4212(c) of ERISA, and each such plan shall also
  be considered an Employee Benefit Plan for purposes of this Agreement. 
  A copy of each trust or other funding arrangement, the most recently
  filed Internal Revenue Service ("IRS") Form 5500, the most recently
  received IRS determination letter for each such plan, the most recently
  completed actuarial valuation for each plan and the applicable summary
  plan description, if any, have been made available to Buyer.
    
   (c)    To the knowledge of the Seller and Bayport, and
  except as described in Schedule 3.14(c) each Employee Benefit Plan has
  been maintained in compliance (including all material filing
  requirements) with the requirements of ERISA and the Code, the violation
  of which would have a material adverse effect on Bayport.
    
   (d)    Each employee pension benefit plan, as defined
  in Section 3(2) of ERISA, and related trust maintained by Bayport is
  qualified as to its written form under Sections 401(a) and 501(a) of the
  Code, except as shown on Schedule 3.14(d).   
    
   (e)    No employee pension benefit plan maintained by
  Bayport has incurred an "accumulated funding deficiency" as such term is
  defined in Section 302 of ERISA and Section 412 of the Code (whether or
  not waived).
    
   (f)    No reportable event, as such term is defined in
  Title IV of ERISA, for which the PBGC has not waived the thirty (30) day
  notice requirement, has occurred with respect to any defined benefit
  pension plan maintained by Bayport.  To the knowledge of the Seller and
  Bayport no prohibited transaction, as such term is defined in Section
  406 of ERISA or Section 4975 of the Code, has occurred with respect to
  any Employee Benefit Plan.  Except as disclosed on Schedule 3.14(f), no
  complete or partial termination has occurred within the five years
  preceding the date hereof with respect to any employee pension benefit
  plan; all contributions, premiums or payments required to be made with
  respect to any Employee Benefit Plan have been made on or before their
  due dates; and Bayport has not incurred any liability under, arising out
  of or by operation of Title IV of ERISA (other than liability for
  premiums arising in the ordinary course).
    
   (g)    Except as disclosed on Schedule 3.14(g), there
  are no actions, suits or claims pending, other than routine claims for
  benefits, with respect to the Employee Benefit Plans and, to the
  knowledge of the Seller or Bayport, there are no such actions, suits or
  claims threatened, arising out of, or in connection with, the existence,
  operation, maintenance or administration of such Employee Benefit Plans.
    
   (h)    Schedule 3.14(h) sets forth a complete and
  accurate list of each Employee Benefit Plan which provides or promises
  retiree medical, disability or life insurance benefits to any current or
  former employee, officer or director of Bayport, and a list of each
  
   8
  
  employee to whom such benefits are provided, specifying which benefits
  are provided to each employee so listed.
    
   (i)    No event has occurred with respect to any
  Employee Benefit Plan maintained by any individual or entity that is or
  has been a member of any group of organizations described in Section
  414(b) or (c) of the Code of which Bayport is a member which would
  result in a liability of Bayport by virtue of Bayport's membership in
  such group.
                      
          3.15. Operations  Bayport owns, leases or has licenses to
  use all Assets being used in and necessary to the operation of Bayport's
  business as currently conducted.
    
          3.16. Laws and Regulations; Litigation  Except as set forth
  in Schedule 3.16, Bayport has not violated and is not in violation of or
  default under any law or regulation, or under any order of any court or
  Federal, state, municipal or other governmental department, commission,
  board, bureau, agency or instrumentality having jurisdiction over
  Bayport, violation of which would have a material adverse effect on
  Bayport or its business or operations, and there are no claims, actions,
  suits or proceedings pending, or to the  knowledge of the Seller and
  Bayport, threatened against or affecting Bayport, at law or in equity,
  before or by any federal, state, municipal or other governmental
  department, commission, board, bureau, agency or instrumentality having
  jurisdiction over Bayport.  
    
              3.17. Taxes  Bayport has filed or will file, on a timely
  basis, all requisite tax and information returns with respect to all
  Federal, state or local taxes imposed upon Bayport and all taxes due
  (whether or not shown on such returns) for all applicable periods ended
  on or before the date hereof have been or will be paid in full when due
  or are or will be reserved for on the financial statements.  There is no
  basis for any claims against Bayport for any such taxes for any period
  or periods prior to and including the date hereof that have not been
  reflected as provisions and reserves for taxes on the Interim Financial
  Statements.  All provisions and reserves are sufficient for the payment
  of all such taxes for all fiscal periods ended on or before that date. 
  Copies of the Federal income, and state franchise, income and sales tax
  returns related directly to Bayport for its fiscal years ended December
  31, 1993 and December 31, 1992 have been or prior to the Closing will
  be, delivered to Buyer.  Copies of all other Federal, state, local and
  other tax and information returns related directly to Bayport have been
  made available to Buyer and are among the records of Bayport, possession
  of which will accrue to Buyer at Closing.  Bayport's Federal income tax
  returns have not been audited since 1987.  Bayport has not granted any
  waiver or extension of applicable statutes of limitation with respect to
  the examination of any tax return.  Seller reserves the right to
  challenge any tax deficiencies assessed and subject to this provision. 
  Seller agrees to pay all professional fees it directly incurs as part of
  this right.
    
          3.18. No Change  Except as shown on Schedule 3.18, from
  September 30,1994 through the date hereof there has not been, except as
  disclosed in the Schedules hereto or as contemplated by this Agreement:
    
 9

   (a)    any material adverse change in the Assets,

   (b)    any damage, destruction or loss (whether or not
  covered by insurance) materially adversely affecting the Assets,
  operations or business of Bayport;
    
   (c)    any change in, or agreement to change,
  (i) ownership of the authorized capital or outstanding securities of
  Bayport, or (ii) the securities of Bayport;
    
   (d)    any declaration or payment of, or any agreement
  to declare or pay, any dividend or distribution in respect of an equity
  interest in or any direct or indirect redemption, purchase or other
  acquisition of any of the Stock;
    
   (e)    except for bonuses to employees in a manner

  assessments, adjustments, costs and expenses (including, without
  limitation, reasonable attorneys' fees and expenses of investigation)

  to be realized by the indemnified party by reason of the facts and
  circumstances giving rise to the indemnifying party's liability.
  
                (e)   The indemnity obligations of the parties
  hereunder and any liability for breach of a party's representations and
  warranties hereunder shall expire automatically on the date eighteen
  (18) months after the Closing Date, except with respect to (i) the
  obligations described in Section 6.1(a)(i)(C) and (ii) a breach of the
  representations and warranties in Section 3.20, both of which shall
  survive for the applicable statute of limitations and (iii) Section 6.1
  (b) which shall survive for a term of five (5) years beginning on the
  Closing Date.

  party in writing thereof.
  
                (b)   If the indemnifying party, within a reasonable

  indemnified party will (upon further notice to the indemnifying party)
  have the right to undertake the defense, compromise or settlement of
  such claim on behalf of and for the account and risk of the indemnifying
  party, subject to the right of the indemnifying party to assume the
  defense of such claim at any time prior to settlement, compromise or
  final determination thereof.  If there is a reasonable probability that
  a claim may materially and adversely affect the indemnified party other
  than as a result of money damages or other money payments, the
  indemnified party shall have the right, at its own cost and expense, to
  defend, compromise or settle such claim.  The indemnifying party shall
  not, without the written consent of the indemnified party, settle or
  compromise any claim or consent to the entry of any judgment which does
  not include as an unconditional term thereof the giving by the claimant
  or the plaintiff to the indemnified party a release from all liability
  in respect of such claim.
