     such Final Adjustment Statement, Seller and its authorized representatives
     shall have full access to the relevant books and records of Buyer and
     Buyer's authorized representatives and employees to the extent necessary to
     complete such Final Adjustment Statement. Subject to Section 1.6(d)(iii)
     below, within ten (10) days following the delivery of such Final Adjustment
     Statement to Buyer, Seller or Buyer, as the case may be, shall pay to the
     other party, by wire transfer of immediately available funds, the

     Statement, Buyer shall notify Seller in writing of such objection within
     the ten (10) day period following the delivery thereof, stating in such
     written objection the reasons therefor and setting forth the Buyer's
     calculation of Buyer's actual Working Capital at the Closing. Upon receipt
     by Seller of such written objection, the parties shall attempt to resolve
     the disagreement concerning the Final Adjustment Statement through
     negotiation.  If Seller and Buyer cannot resolve such disagreement
     concerning the Final Adjustment Statement within thirty (30) days following
     the end of the foregoing 10-day period, the parties shall submit the matter
     for resolution to a nationally recognized firm of independent certified
     public accountants not affiliated with either party, with the costs thereof
     to be shared equally by the parties.  Such accounting firm shall deliver a
     statement setting forth its own calculation of the final adjustment to the
     parties within thirty (30) days of the submission of the matter to such
     firm.  Any payment shown to be due by a party on the statement of such
     accounting firm shall be paid to the other party promptly but in no event
     later than five (5) days following the delivery of such statement by such
     accounting firm to the parties.

     1.7  Purchase Price Allocation.  At least ten (10) days prior to the
          -------------------------                                      
Closing, Buyer and Seller shall agree on the allocation of the Purchase Price as
set forth on Schedule 1.7 attached hereto.  Such allocation shall be binding
             ------------                                                   
upon Buyer and Seller for all purposes (including financial accounting purposes,
financial and regulatory reporting purposes and tax purposes).  Buyer and Seller
each further agrees to file its Federal income tax returns and its other tax
returns reflecting such allocation, Form 8594 and any other reports required by
Section 1060 of the Code.

     1.8  Records and Contracts.  To the extent not previously provided to
          ---------------------                                           
Buyer, at the Closing, Seller shall deliver to Buyer all of the Contracts, with
such assignments thereof and consents to assignments as are necessary to assure
Buyer of the full benefit of the same (other than as provided in Sections 4.4
and 6.5 hereof).  Seller shall also deliver to Buyer at the Closing constructive
possession of all of Seller's files and records constituting Assets.

                                       7

     1.9  Further Assurances.  Seller, from time to time after the Closing at
          ------------------                                                 
the request of Buyer and without further consideration, shall execute and
deliver further instruments of transfer and assignment and take such other
action as Buyer may reasonably require to more effectively transfer and assign
to, and vest in, Buyer the Assets free and clear of all Liens (as defined in
Section 2.8).

     1.10 Sales and Transfer Taxes.  All sales, transfer, use, recordation,
          ------------------------                                         
documentary, stamp, excise taxes, personal property taxes, fees and duties
(including any real estate transfer taxes) under applicable law incurred in
connection with this Agreement or the transactions contemplated thereby will be
borne and paid by Seller, and Seller shall promptly reimburse Buyer for the
payment of any such tax, fee or duty which Buyer is required to make under
applicable law.

     1.11 Transfer of Subject Assets.  At the Closing, Seller shall deliver or
          --------------------------                                          
cause to be delivered to Buyer good and sufficient instruments of transfer
transferring to Buyer title to all of the Assets.  Such instruments of transfer
shall be in form and substance reasonably satisfactory to Buyer and its counsel.

     1.12 Accounts Receivable.  Buyer shall receive from Seller and Seller shall
          -------------------                                                   
transfer to Buyer all of the Accounts Receivable at the Closing.  For a period
of ninety (90) days after the Closing (the "Buyer Collection Period"), Buyer
shall have the sole and exclusive right to collect the Accounts Receivable.  So
long as the Accounts Receivable are in Buyer's possession, neither Seller nor
its agents shall make any solicitation for collection purposes nor institute
litigation for the collection of any amounts due thereunder, except for such
Accounts Receivable which Buyer has consented to Seller's collection thereof
prior to the expiration of the Buyer Collection Period.  All payments received
by Buyer during the Buyer Collection Period from any person obligated with
respect to any of the Accounts Receivable shall be for Buyer's account.  Any
payment made by an account debtor to Buyer with respect to such an Account
Receivable shall be applied to such Account Receivable before it is applied to
any outstanding account receivable from such account debtor arising from sales
made by the Buyer after the Closing Date.  The payment by an account debtor
shall be applied to such Account Receivable in inverse order of aging,
commencing with the oldest invoice.  Buyer shall use commercially reasonable
efforts to collect Accounts Receivable during the Buyer Collection Period.  All
of the right, title and interest in and to the Accounts Receivable which are
aged for more than thirty (30) days as of the Closing Date and that are not
collected during the Buyer Collection Period shall be assigned to Seller at the
end of the Buyer Collection Period at fair value, after which Buyer shall have
no further right or obligation with respect to the Accounts Receivable and
hereby agrees to promptly remit to the Seller any payment on such uncollected
accounts which it may thereafter receive; provided, however, that nothing
                                          --------  -------              
contained in this Section 1.12 shall be construed to grant Seller any right with
respect to any accounts receivable accrued in connection with Buyer's operation
of the Business on or after the Closing Date. Following the Buyer Collection
Period, Buyer shall make available to Seller, upon the reasonable request of
Seller, copies of all of its records relating to any uncollected Accounts
Receivable assigned to Seller and agrees that Seller may commence legal
proceedings or take 

                                       8
<PAGE>
 
such other action as it considers appropriate to collect any such uncollected
Account Receivable. Notwithstanding anything provided in this Section 1.12 to
the contrary, Seller shall not be required to repurchase any such uncollected
Account Receivable if the reason for nonpayment by such account debtor is any
right of setoff or other claim arising out of any act or omission of the Buyer
after the Closing.

SECTION 2. REPRESENTATIONS AND WARRANTIES OF SELLER AND PRINCIPALS.  In order to
induce Buyer to enter into this Agreement, Seller and the Principals jointly and
severally hereby make the following representations and warranties to Buyer.  As

           (a) Except as set forth on Schedule 2.1(a), Seller is a corporation

duly organized, validly existing and in good standing under the laws of the
State of Wisconsin, with full corporate power and authority to own or lease its
properties and to conduct its business in the manner and in the places where
such properties are owned or leased or such business is currently conducted or
proposed to be conducted.  The copies of Seller's Articles of Incorporation and
by-laws, each as amended to date, heretofore delivered to Buyer's counsel are
complete and correct.  Seller is not in violation of any term of its Articles of
Incorporation or by-laws.  Except as set forth on Schedule 2.1(a), Seller is
                                                  ---------------           
duly qualified to do business in the state of its organization, and, to the
knowledge of Seller and Principals, is duly qualified as a foreign corporation
in each jurisdiction in which the character or location of the properties owned
or leased by Seller in the operation of the Business makes qualification to do
business as a foreign corporation necessary, except for such jurisdictions where
failure to so qualify would not have a Material Adverse Effect.  For the
purposes of this Agreement, a "Material Adverse Effect" shall mean a material
adverse effect upon the assets, properties, business, prospects, condition
(financial or other) or results of operations of Seller or the Business, taken
as a whole.

           (b) Except as set forth on Schedule 2.1(b), Seller has no
                                      ---------------

organization or governmental authority, except U.S. Government securities, bank
certificates of deposit and money market accounts acquired as short-term
investments in the ordinary course of its business. Except as set forth on
Schedule 2.1(b), Seller does not own or have any direct or indirect interest in
---------------
or control over any corporation, partnership, joint venture or entity of any
kind.

     2.2   Required Action. All actions and proceedings necessary to be taken by
           ---------------
or on the part of Seller in connection with the transactions contemplated by
this Agreement have

                                       9
<PAGE>
 
been duly and validly taken, and this Agreement and each other agreement,
document and instrument to be executed and delivered by or on behalf of Seller
pursuant to, or as contemplated by, this Agreement (collectively, the "Seller
Documents") has been duly and validly authorized, executed and delivered by
Seller and no other action on the part of Seller or its stockholders is required
in connection therewith. Each of Seller and the Principals have full right,
authority, power and capacity to execute and deliver this Agreement and each
other Seller Document and to carry out the transactions contemplated hereby and
thereby. This Agreement and each other Seller Document constitutes, or when
executed and delivered will constitute, the legal, valid and binding obligation
of each of Seller and the Principals enforceable in accordance with its
respective terms, except as may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting creditors' rights
generally or by the application of general principles of equity.

     2.3  No Conflicts.
          ------------ 

          (a) Except as set forth on Schedule 2.3, the execution, delivery and
                                     ------------                             
performance by Seller of this Agreement and each other Seller Document does not
and will not (i) violate any provision of the Articles of Incorporation or by-
laws of Seller, in each case as amended to date, (ii) except as will not result
in a Material Adverse Effect, constitute a violation of, or conflict with or
result in any breach of, acceleration of any obligation under, right of
termination under, or default under, any agreement or instrument to which Seller
is a party or by which Seller or the Assets is bound, (iii) except as will not
result in a Material Adverse Effect, violate any judgment, decree, order,
statute, rule or regulation applicable to Seller or the Assets, (iv) except as
set forth in Sections 4.4, 6.5 and 7.5 hereof, require Seller to obtain any
approval, consent or waiver of, or to make any filing with, any person or entity
(governmental or otherwise) that has not been obtained or made or (v) result in
the creation or imposition of any Lien on any of the Assets.

          (b) The execution, delivery and performance by each of the Principals
of this Agreement and each other Seller Document does not and will not (i)
constitute a violation of, or conflict with or result in any breach of,
acceleration of any obligation under, right of termination under, or default
under, any agreement or instrument to which each such Principal is a party or by
which such Principal is bound, (ii) violate any judgment, decree, order,
statute, rule or regulation applicable to each such Principal, (iii) require
such Principal to obtain any approval, consent or waiver of, or to make any
filing with, any person or entity (governmental or otherwise) that has not been
obtained or made, or (iv) result in the creation or imposition of any Lien on
any of the Assets.

     2.4  Taxes.
          ----- 

          (a) Except as set forth on Schedule 2.4, Seller has paid or caused to
                                     ------------                              
be paid all federal, state, local, foreign and other taxes, including, without
limitation, income taxes, estimated taxes, alternative minimum taxes, excise
taxes, sales taxes, use taxes, value-added taxes, gross receipts taxes,
franchise taxes, capital stock taxes, employment and payroll-related 

                                       10
<PAGE>
 
taxes, withholding taxes, stamp taxes, transfer taxes, windfall profit taxes,
environmental taxes and property taxes, whether or not measured in whole or in
part by net income, and all deficiencies, or other additions to tax, interest,
fines and penalties owed by it (collectively, "Taxes"), required to be paid by
it through the date hereof whether disputed or not.

          (b) Seller has in accordance with applicable law filed all federal,
state, local and foreign tax returns required to be filed by it through the date
hereof, and to the knowledge of Seller and the Principals, all such returns
correctly and accurately set forth the amount of any Taxes relating to the
applicable period.  A list of all federal, state, local and foreign income tax
returns filed with respect to Seller for taxable periods ended on or after
December 31, 1993, is set forth in Schedule 2.4 attached hereto, and said
                                   ------------                          
schedule indicates those returns that have been audited or currently are the
subject of an audit.  Seller has delivered to Buyer correct and complete copies
of all federal, state, local and foreign income tax returns listed on said
schedule, and of all examination reports and statements of deficiencies assessed
against or agreed to by Seller with respect to said returns.

          (c) Neither the Internal Revenue Service nor any other governmental
authority is now asserting or, to the knowledge of Seller or the Principals,
threatening to assert against Seller any deficiency or claim for additional
Taxes.  No claim has ever been made by an authority in a jurisdiction where
Seller does not file reports and returns that Seller is or may be subject to
taxation by that jurisdiction.  There are no security interests on any of the
Assets of Seller that arose in connection with any failure (or alleged failure)
to pay any Taxes.  Seller has never entered into a closing agreement pursuant to
Section 7121 of the Internal Revenue Code of 1986, as amended (the "Code").

          (d) Except as set forth in Schedule 2.4, there has not been any audit
                                     ------------                              
of any tax return filed by Seller, no audit of any tax return of Seller is in
progress, and Seller has not been notified by any tax authority that any such
audit is contemplated or pending.  Except as set forth in Schedule 2.4, no
                                                          ------------    
extension of time with respect to any date on which a tax return was or is to be
filed by Seller is in force, and no waiver or agreement by Seller is in force
for the extension of time for the assessment or payment of any Taxes.

          (e) Seller has never been (and has never had any liability for unpaid
Taxes because it once was) a member of an "affiliated group" (as defined in
Section 1504(a) of the Code).  Seller has never filed, and has never been
required to file, a consolidated, combined or unitary tax return with any other
entity.  Except as set forth in Schedule 2.1(b), Seller does not own and has
                                ---------------                             
never owned a direct or indirect interest in any trust, partnership, corporation
or other entity and therefore Buyer is not acquiring from Seller an interest in
any entity.  Except as set forth in Schedule 2.4, Seller is not a party to any
                                    ------------                              
tax sharing agreement.

          (f) Seller is, and at all times since January 2, 1992 has been, a
"small business corporation" with a valid election pursuant to Section 1362(a)
of the Code and applicable state law.

                                       11
<PAGE>
 
          (g) Seller is not a "foreign person" within the meaning of Section
1445 of the Code and Treasury Regulations Section 1.1445-2.

          (h) For purposes of this Agreement, all references to Sections of the
Code shall include any predecessor provisions to such Sections and any similar
provisions of federal, state, local or foreign law.

     2.5  Compliance with Laws.  Except as set forth on Schedule 2.5 and
          --------------------                          ------------    
Schedule 2.7, Seller's operation of the Business and the Assets is in compliance
------------                                                                    
in all material respects with all applicable statutes, ordinances, orders, rules
and regulations promulgated by any federal, state, municipal or other
governmental authority (including the Federal Communications Commission), and,
to the knowledge of Seller and the Principals, Seller has not received notice of
a violation or alleged violation of any such statute, ordinance, order, rule or
regulation within the last three (3) years.

     2.6  Insurance.  The physical properties and tangible Assets are insured to
          ---------                                                             
the extent disclosed in Schedule 2.6, and all insurance policies and
                        ------------                                
arrangements of Seller in effect as of the date hereof are disclosed in said
Schedule.  Said insurance policies and arrangements are in full force and
effect, all premiums with respect thereto are currently paid, and Seller is in
compliance in all material respects with the terms thereof.  Except as set forth
on Schedule 2.6, said insurance is adequate and customary for the business
   ------------                                                           
engaged in by Seller and is sufficient for compliance by Seller with all
requirements of law and all agreements and leases to which Seller is a party.

     2.7  Contracts.  Except for the Excluded Contracts, the Contracts
          ---------                                                   
constitute all leases, contracts and arrangements, whether oral or written,
under which Seller is bound or to which Seller is a party which relate to the
Business or Assets.  To the knowledge of Seller and the Principals, Schedule
                                                                    --------
1.1(b) attached hereto contains a true, correct and complete list of all
------                                                                  
Contracts (and a description of each oral arrangement, if any).  Each Contract
is valid, in full force and effect and binding upon Seller and, to the knowledge
of Seller and the Principals, the other parties thereto in accordance with its
terms.  Except as set forth on Schedule 2.7 and except as will not result in a
                               ------------                                   
Material Adverse Effect, neither Seller nor, to the knowledge of Seller and the
Principals, any other party is in default under or in arrears in the
performance, payment or satisfaction of any agreement or condition on its part
to be performed or satisfied under any Contract, nor does any condition exist
that with notice or lapse of time or both would constitute such a default, and
no waiver or indulgence has been granted by any party under any Contract.
Except as set forth on Schedule 2.7, Seller has not received notice of, and each
                       ------------                                             
of Seller and the Principals has no knowledge of, any fact which would result in
a termination, repudiation or breach of any Contract.  Seller has provided Buyer
with true and complete copies of all of such Contracts, as amended, other than
Contracts with Subscribers. With respect to Subscriber Contracts, Seller has
provided Buyer with representative forms of such Contracts which Seller
reasonably believes to be the form utilized by it for all such Subscribers.

     2.8  Title.  Seller has good and marketable title to all of the Assets free
          -----

restrictions and encumbrances of any kind (collectively, "Liens") whatsoever,
except for the Liens set forth on Schedule 2.8 (other than those Liens which are
                                  ------------

Closing) which are to be transferred to Buyer in connection with the transfer of
the Assets (the "Permitted Liens").  Upon the sale, assignment, transfer and
delivery of the Assets to Buyer hereunder and under the Seller Documents, there
will be vested in Buyer good, marketable and indefeasible title to the Assets
free and clear of all Liens, except for the Permitted Liens.  Except for the
Excluded Assets, the Assets include all of the assets and properties (i) held
for use by Seller to conduct the Business as presently conducted and (ii)
necessary for Buyer to operate the Business in the same manner as such business
is currently operated by Seller.  Except as set forth on Schedule 2.8, all of
                                                         ------------        
the tangible Assets, taken as a whole, are in good repair, have been well
maintained and are in good operating condition, ordinary wear and tear excepted,
do not require any material modifications or repairs, and comply in all material

and the Principals, subject only to the right of reversion of the landlord or
lessor under the Leases, free and clear of all other prior or subordinate
interests, including, without limitation, mortgages, deeds of trust, ground
leases, leases, subleases, assessments, tenancies, claims, covenants,

improvements constituting a part of the Leased Real Property, including, without
limitation, structural elements, mechanical systems, roofs or parking and
loading areas, and all of such improvements, taken as a whole, are in good
operating condition and repair, have been well maintained, ordinary wear and
tear excepted.  All water, sewer, gas, electric, telephone, drainage and other
utilities required by law or necessary for the current or planned operation of
the Leased Real Property have been installed and connected pursuant to valid
permits, and are sufficient to service the Leased Real Property.

Schedule 2.12 hereto is a list of all such employees, including the name, date
-------------

wages, salaries, commissions, bonuses or other direct compensation for any
services performed for it to the date hereof or amounts required to be
reimbursed to such employees. Upon termination of the employment of any of said
employees, neither Seller nor Buyer will, by reason of the acquisition
transaction or anything done prior to the Closing, be liable to any of said
employees for any bonus or compensation payments, except as set forth in
Schedule 2.10 and except for accrued sick, vacation and holiday pay, if any.

pay or any form of severance compensation in connection with the termination of
employment, except as set forth in such Schedule 2.10. Except as set forth on

interests in the source code of the Products, and (ii) since Seller developed

the source code of the Products to any person or entity.  Seller has the right
to use, free and clear of claims of third parties, all Trade Secrets.  To the

by Seller of any Trade Secret violates the rights of any third party.

exclusive right to use, license, distribute, transfer and bring infringement
actions with respect to the Intellectual Property.  Except as set forth on

-------------                                                                
nature to use any of its Intellectual Property and (ii) is not obligated to and
does not pay royalties or other fees to anyone for its ownership, use, license
or transfer of any of its Intellectual Property.

          (h) All licenses or other agreements under which Seller is granted
rights by others in Intellectual Property are listed in Schedule 2.20.  Except
                                                        -------------

material default by any party thereto, and all of the rights of Seller
thereunder are freely assignable.  True and complete copies of all such licenses
or other agreements, and any amendments thereto, have been provided to Buyer,
and Seller has no reason to believe that the licensors under the licenses and
other agreements under which Seller is granted rights and has granted rights to
others do not have and did not have all requisite power and authority to grant
the rights purported to be conferred thereby.

          (i) All licenses or other agreements under which Seller has granted
rights to others in Intellectual Property are listed in Schedule 2.20.  All such
                                                        -------------           
licenses or other agreements are in full force and effect, and to the knowledge
of Seller and the Principals there is no material default by any party thereto.
True and complete copies of all such licenses or other agreements, and any

          (j) Seller has no obligation to any other person to maintain, modify,
improve or upgrade the Products other than in the ordinary course of business
consistent with past practices of Seller.

          (k) None of the Products manufactured and sold, nor any process or
know-how used, by Seller infringes or is alleged to infringe any patent,
trademark, service mark, trade name, copyright or other proprietary right or is
a derivative work based on the work of any other person.

          (l) Except as set forth on Schedule 2.9, there are no (i) actions,
                                     ------------                           
suits, claims, investigations or other proceedings involving the Products, the
Intellectual Property, or the Rights by or before any governmental authority or
arbitrator pending or, to the knowledge of Seller and the Principals, threatened
against Seller, or (ii) judgments, decrees, injunctions, or orders involving the
Products, the Intellectual Property or the Rights of any governmental authority
or arbitrator against Seller.  Seller is not in default under any such judgment,
decree, injunction or order.

          (m) The Products perform in accordance with their published
specifications and documentation and as Seller has warranted to its customers.
Seller has reviewed the areas within its businesses and operations which could
be adversely affected by, and has developed a program to address on a timely
basis, the "Year 2000 Problem" (i.e., the risk that applications used by Seller
or its suppliers and/or providers may be unable to recognize and properly
perform date-sensitive functions involving certain dates prior to and any date
after December 31, 1999).  Seller reasonably believes that the "Year 2000
Problem" will not have a Material Adverse Effect.

authorities in order for Seller to conduct its Business.  Seller has obtained
all such Approvals, which are valid and in full force and effect, and is
operating in compliance therewith.  Such Approvals include, but are not limited
to, those required under federal, state or local statutes, ordinances, orders,
requirements, rules, regulations, or laws pertaining to environmental
protection, public health and safety, worker health and safety, buildings,
highways or zoning.  Except as disclosed in Schedule 2.22 and Schedule 2.14 and

conduct the business currently conducted by Seller subsequent to the Closing.

distributed).  No material event or omission has occurred which would cause any
such Employee Program to lose its qualification under the applicable Code
section.

          (c) Seller does not know, and has no reason to know, of any material
failure of any party to comply with any laws applicable to the Employee Programs
that have been maintained by Seller.  With respect to any Employee Program ever
maintained by Seller or any Affiliate, there has occurred no "prohibited
transaction," as defined in Section 406 of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA") or Section 4975 of the Code, or
breach of any duty under ERISA or other applicable law (including, without
limitation, any health care continuation requirements or any other tax law
requirements, or conditions to favorable tax treatment, applicable to such
plan), which could result, directly or indirectly (including, without
limitation, through any obligation of indemnification or contribution), in any
taxes, penalties or other liability to Buyer.  No litigation, arbitration, or
governmental administrative proceeding (or investigation) or other proceeding
(other than those relating to routine claims for benefits) is pending or, to the
knowledge of Seller or the Principals, threatened with respect to any such
Employee Program.

          (d) Neither Seller nor any Affiliate (i) has ever maintained any
Employee Program which has been subject to Title IV of ERISA (including, but not
limited to, any Multiemployer Plan (as defined below)) or (ii) has ever provided
health care or any other non-pension benefits to any employees after their
employment is terminated (other than as 

                                       21
<PAGE>
 
required by part 6 of subtitle B of title I of ERISA) or has ever promised to
provide such post-termination benefits.

          (e)  With respect to each Employee Program maintained by Seller within
the three (3) years preceding the Closing, complete and correct copies of the
following documents (if applicable to such Employee Program) have previously
been delivered to Buyer:  (i) all documents embodying or governing such Employee
Program, and any funding medium for the Employee Program (including, without
limitation, trust agreements) as they may have been amended; (ii) the most
recent IRS determination or approval letter with respect to such Employee
Program under Code Section 401 or 501(c)(9), and any applications for
determination or approval subsequently filed with the IRS; (iii) the three most
recently filed IRS Forms 5500, with all applicable schedules and accountants'
opinions attached thereto; (iv) the summary plan description for such Employee
Program (or other descriptions of such Employee Program provided to employees)
and all modifications thereto; (v) any insurance policy (including any fiduciary
liability insurance policy) related to such Employee Program; (vi) any documents
evidencing any loan to an Employee Program that is a leveraged employee stock
ownership plan; and (vii) all other materials reasonably necessary for Buyer to
perform any of its responsibilities with respect to any Employee Program
subsequent to the Closing (including, without limitation, health care
continuation requirements).

          (f)  For purposes of this section:

               (i)   "Employee Program" means (A) all employee benefit plans
     within the meaning of ERISA Section 3(3), including, but not limited to,
     multiple employer welfare arrangements (within the meaning of ERISA Section
     3(4)), plans to which more than one unaffiliated employer contributes and
     employee benefit plans (such as foreign or excess benefit plans) which are
     not subject to ERISA; and (B) all stock or cash option plans, restricted
     stock plans, bonus or incentive award plans, severance pay policies or
     agreements, deferred compensation agreements, supplemental income
     arrangements, vacation plans, and all other employee benefit plans,
     agreements, and arrangements not described in (A) above.  In the case of an
     Employee Program funded through an organization described in Code Section
     501(c)(9), each reference to such Employee Program shall include a
     reference to such organization.

               (ii)  An entity "maintains" an Employee Program if such entity
     sponsors, contributes to, or provides (or has promised to provide) benefits
     under such Employee Program, or has any obligation (by agreement or under
     applicable law) to contribute to or provide benefits under such Employee
     Program, or if such Employee Program provides benefits to or otherwise
     covers employees of such entity, or their spouses, dependents, or
     beneficiaries.

               (iii) An entity is an "Affiliate" of Seller if it would have ever
     been considered a single employer with Seller under ERISA Section 4001(b)
     or part of the same "controlled group" as Seller for purposes of ERISA
     Section 302(d)(8)(C).

                                       22
<PAGE>
 
               (iv)  "Multiemployer Plan" means a (pension or non-pension)
     employee benefit plan to which more than one employer contributes and which
     is maintained pursuant to one or more collective bargaining agreements.

     4.4  Consents.
          -------- 

          (a) Seller will use its reasonable best efforts to obtain, with
Buyer's assistance, as soon as practicable and at its expense, the consent of
all third parties under the Contracts for which the prior approval of such third
party is required pursuant to the terms of the Contract (each a "Restricted
Contract," and together the "Restricted Contracts"), in form and substance
reasonably satisfactory to Buyer.  If any such consent or approval is not
obtained, or if any approval, consent or authorization for the Authorizations
described in Section 2.13 and 2.14 hereof is not obtained ("Restricted
Authorizations"), and the parties nonetheless consummate the transactions
contemplated hereby, Seller shall use reasonable best efforts to obtain such
consent after the Closing and secure an arrangement satisfactory to Buyer to
provide Buyer with the benefits of such Restricted Authorization or Restricted
Contract after Closing until such consent is obtained; provided, however, that
                                                       --------  -------      
"reasonable best efforts" for these purposes shall not require Seller to
undertake extraordinary or unreasonable measures to obtain such authorizations,
approvals and consents, including, without limitation, the initiation or
prosecution of legal proceedings or the payment of fees in excess of customary
filing and processing fees.  If Seller shall have complied with this Section
4.4(a), Buyer shall have no right to terminate this Agreement or to seek
indemnification or other remedies from Seller as a result of any failure by the
parties to obtain any such authorization, consent or approval or to provide any
such alternative arrangement with respect to any Restricted Contract or
Restricted Authorization.

          (b) Notwithstanding the foregoing, with respect to the Restricted
Authorizations and the Restricted Contracts which have been marked with a * on
Schedule 2.14 (the "Material Restricted Authorizations" and the "Material
-------------                                                            
Restricted Contracts", respectively), Buyer and Seller agree that it shall be a
condition to Buyer's obligation to consummate the transactions contemplated
hereby that Seller obtain the consents to the assignment thereof; provided,
                                                                  -------- 
however, that with respect to the Material Restricted 
-------                                                                       

                                       27
<PAGE>
 
Contracts with M&I First National Leasing Corp., Fleet Capital, 3Com Credit
Corporation and Ameritech Credit Corporation set forth on Schedule 2.14 (the
                                                          ------------- 
"Material Leases"), if the consent to the assignment of such Material Leases is
not obtained, in form and substance reasonably satisfactory to Buyer, prior to
October 1, 1998, then Buyer and Seller agree that such Material Leases will be
paid-in-full by Buyer at the Closing, including payment of all interest,
prepayment and termination penalties, and other charges related thereto, without
any further liability of Seller and the Principals to Buyer under such Material
Leases after the Closing (it being understood by the parties that the adjustment
to the Purchase Price as contemplated by Section 1.6(b) shall still apply).

          (c) Nothing in this Agreement will constitute a transfer or an
attempted transfer of any Restricted Authorization or Restricted Contract which
by its terms or under applicable law or governmental rules or regulations
requires the consent or approval of a third party (including, without
limitation, a governmental authority) unless such consent or approval shall have
been obtained.

     4.5  Notification of Certain Matters.  Seller shall promptly notify Buyer
          -------------------------------                                     
of (i) any fact, event, circumstances or action the existence or occurrence of
which would cause any of Seller's representations or warranties under this
Agreement, or the disclosures in any schedules or exhibits attached hereto, not
to be true in any material respect and (ii) any failure on its part to comply
with or satisfy in any material respect any covenant, condition or agreement to
be complied with or satisfied by it under this Agreement.  Seller shall promptly
notify buyer in writing of the assertion, commencement or threat of any claim,
litigation, proceeding or investigation in which Seller is a party or in which
the Assets or Business may be affected and which could reasonably be expected to
be material or which relates to the transactions contemplated hereby.  Prior to
the Closing, the Seller may modify, supplement or amend the Schedules.  The
parties agree that Buyer shall be deemed to have waived, and Seller shall have
no obligation to indemnify Buyer with respect to, any breach by Seller of any
warranties and representations of Seller under this Agreement disclosed in any
modification, supplement or amendment in the Schedules made pursuant hereto,
except for such breaches of representations and warranties which are the result
of a breach or default by Seller with respect to any covenant of Seller made in
Section 4 of this Agreement, unless the Buyer shall notify Seller within three
(3) days of receipt thereof or at Closing, whichever is earlier, of Buyer's
election to terminate this Agreement, in which case Buyer shall be permitted to
terminate this Agreement as provided in Section 8.3 without either party having
any liability to the other party for indemnification or otherwise.  If Buyer
does not so notify Seller, the Schedules shall be deemed modified by the
information disclosed in any such supplement or amendment and the same shall be
incorporated in the Schedules by reference.

     4.6  Adverse Change.  Seller shall promptly notify Buyer in writing of any
          --------------

adversely affecting any of the Assets or the Business, (ii) any material notice
of violation, forfeiture or complaint under any material Contract, or (iii)

                                       28

anything which, if not corrected prior to the Closing Date, would prevent Seller
from fulfilling any condition to Closing described in Section 6 hereof.

     4.7  No Solicitation.  Seller shall not, and Seller shall cause its
          ---------------                                               
officers, employees, stockholders, agents and representatives (including,
without limitation, any investment banker, attorney or accountant retained by
Seller) and all other employees who perform services with respect to the
operation of the Business not to, initiate, solicit or encourage, directly or
indirectly, any inquiries or the making of any proposal with respect to the
Assets or the Business, or engage in any negotiations concerning, or provide to
any other person any information or data relating to, the Business, the Assets
or Seller for the purpose of, or have any discussions with, any person relating
to, or otherwise cooperate in any way with or assist or participate in,
facilitate or encourage, any inquiries or the making of any proposal which
constitutes, or may reasonably be expected to lead to, any effort or attempt by
any other person to seek or effect a transaction, or enter into a transaction
with any person or persons, other than Buyer, concerning the possible sale of
the Assets or Business, or the capital stock of Seller.  Seller shall promptly
inform Buyer of any such inquiries or proposals and provide all pertinent
documentation related thereto.

     4.8  Cooperation.  Seller shall use its commercially reasonable efforts to
          -----------                                                          
take all steps within its power and will cooperate with Buyer to cause to be
fulfilled those of the conditions to Buyer's obligations to consummate the
transactions contemplated by this Agreement that are dependent upon its actions,
and to execute and deliver such instruments and take such other reasonable
actions as may be necessary or appropriate in order to carry out the intent of
this Agreement and consummate the transactions contemplated hereby.  Without
limiting the foregoing, Seller shall cooperate with all reasonable requests of
Buyer and its counsel in connection with Buyer's due diligence investigation of
the Business and Assets.

     4.9  Expenses.  Seller shall bear its own expenses incurred in connection
          --------                                                            
with the negotiation and preparation of this Agreement and in connection with

SECTION 10.  INDEMNIFICATION.

     10.1 Indemnification by Seller.
          ------------------------- 

          (a) Except as set forth in Section 9.3 hereof, Seller hereby agrees to
indemnify and hold harmless Buyer, its affiliates and its and their respective
directors, officers, stockholders, partners, members, employees, and agents
(individually, a "Buyer Indemnified Party" and collectively, "Buyer Indemnified
Parties"), against and in respect of all losses, liabilities, obligations,
damages, deficiencies, actions, suits, proceedings, demands, assessments,
orders, judgments, costs and expenses (including the reasonable fees,
disbursements and expenses of attorneys and consultants) of any kind or nature
whatsoever, but net of the proceeds from any insurance policies or other third
party reimbursement for such loss, to the extent sustained, suffered or incurred
by or made against any Buyer Indemnified Party, to the extent based upon,
arising out of or in connection with:  (i) any breach of any representation or
warranty made by Seller in this Agreement or in any schedule, exhibit,
certificate, agreement or other instrument delivered pursuant to this Agreement;
(ii) any breach of any covenant or agreement made by Seller in this Agreement or
in any schedule, exhibit, certificate, financial statement, agreement or other
instrument delivered pursuant to this Agreement; (iii) any claim made by any
person or entity which relates to the operation of the Assets or the Business
which arises in connection with or on the basis of events, acts, omissions,
conditions or any other state of facts occurring on or existing before the
Closing Date (other than events, acts, omissions, conditions or any other state
of facts which Buyer has been provided specific written notice at or prior to
the Closing); and (iv) any claim which arises in connection with any liability
or obligation of Seller other than the Assumed Liabilities (and the liabilities
or obligations existing as of the Closing Date and the existence of which has
been disclosed by Seller in writing to Buyer).

          (b) The following provisions shall apply with respect to this Section
10.1:

              (i) all rights to indemnification under this Section 10.1 shall
     expire on the Expiration Date and no Buyer Indemnified Party shall have the
     right to make any claim hereunder after such date, except that if prior to
     the Expiration Date a specific state of facts shall have become known which
     may constitute or give rise to any claim as to which indemnity may be
     payable and a Buyer Indemnified Party shall have given written notice of
     such facts to Seller, then the right to indemnification with respect
     thereto shall remain in effect without regard to when such matter shall
     have been finally determined and disposed of, according to the date on
     which notice of the applicable claim is given;

                                       37
<PAGE>
 
               (ii)  no indemnification shall be payable to any Buyer
     Indemnified Party pursuant to this Section 10.1 with respect to any claim
     unless and until the total of all claims for indemnification shall exceed
     One Hundred Thousand Dollars ($100,000) in the aggregate, and then only to
     the extent of the excess;

               (iii) Seller's aggregate liability under this Section 10.1 shall
     not exceed One Million Two Hundred Fifty Thousand Dollars ($1,250,000) in
     the aggregate (except from claims made with respect to a breach of warranty
     or representation under Sections 2.4, 2.8 (title only) and 2.27 (to the
     extent, and only to the extent, it relates to matters covered by Section
     2.4 or Section 2.8 (title only)), which shall have no limits and which
     shall not count against the cap set forth herein);

               (iv)  a Buyer Indemnified Party shall only be entitled to its
     actual, out-of-pocket damages and expenses, and no indemnification shall be
     payable under this Section 10.1 for any consequential or special damages or
     any expected profits or multiples thereof;

               (v)   if the Closing occurs, the rights to indemnification set
     forth in this Section 10.1 shall be exclusive of all rights to
     indemnification or other remedies that any Buyer Indemnified Party would
     otherwise have in connection with the matters and transactions contemplated
     by this Agreement; and

               (vi)  all claims for indemnification made under this Section 10.1
     shall be recovered solely by proceeding against the Escrow Deposit pursuant
     to the terms of the Escrow Agreement and this Section 10.1, and no such
     claim may be recovered directly against Seller, its partners, or their
     respective affiliates, directors, officers, stockholders, or agents (except
     for claims made with respect to a breach of warranty or representation
     under Sections 2.4, 2.8 (title only) and 2.27 (to the extent, and only to
     the extent, it relates to matters covered by Section 2.4 or 2.8 (title
     only))).

     10.2 Indemnification by Buyer.  Except as set forth in Section 9.3, Buyer
          ------------------------                                            
agrees to indemnify and hold harmless Seller and its officers, directors,
stockholders, employees and agents (individually, a "Seller Indemnified Party"
and collectively, "Seller Indemnified Parties") at all times against and in
respect of all losses, liabilities, obligations, damages, deficiencies, actions,
suits, proceedings, demands, assessments, orders, judgments, costs and expenses
(including the reasonable fees, disbursements and expenses of attorneys and
consultants), of any kind or nature whatsoever, to the extent sustained,
suffered or incurred by or made against any Seller Indemnified Party, to the
extent based upon, arising out of or in connection with: (A) any breach of any
representation or warranty made by Buyer in this Agreement or in any schedule,
exhibit, certificate, agreement or other instrument delivered pursuant to this
Agreement; (B) any breach of any covenant or agreement made by Buyer in this
Agreement or in any schedule, exhibit, certificate, agreement or other
instrument delivered pursuant to this Agreement; (C) any claim made against
Seller which relates to, results from or 

                                       38
<PAGE>
 
arises out of Buyer's operation of the Assets or the Business from and after the
Closing Date; and (D) the Assumed Liabilities.

     10.3 Notice; Defense of Claims.
          ------------------------- 

          (a) Notice of Claims.  Promptly after receipt by an indemnified party
              ----------------                                                 
of notice of any claim, liability or expense to which the indemnification
obligations hereunder would apply, the indemnified party shall give notice
thereof in writing to the indemnifying party, but the omission to so notify the
indemnifying party promptly will not relieve the indemnifying party from any
liability except to the extent that the indemnifying party shall have been
prejudiced as a result of the failure or delay in giving such notice or is
required to pay a greater amount with respect to any such claim or liability as
a result of the failure to provide prompt notice.  Such notice shall state the
information then available regarding the amount and nature of such claim,
liability or expense and shall specify the provision or provisions of this
Agreement under which the liability or obligation is asserted.

          (b) Third Party Claims.  With respect to third party claims, if within
              ------------------                                                
twenty (20) days after receiving the notice described in clause (a) above the
indemnifying party gives (i) written notice to the indemnified party stating
that (A) it would be liable under the provisions hereof for indemnity in the
amount of such claim if such claim were successful and (B) that it disputes and
intends to defend against such claim, liability or expense at its own cost and
expense and (ii) provides reasonable assurance to the indemnified party that
such claim will be promptly paid in full if required, then counsel for the
defense shall be selected by the indemnifying party (subject to the consent of
the indemnified party which consent shall not be unreasonably withheld) and the
indemnified party shall not be required to make any payment with respect to such
claim, liability or expense as long as the indemnifying party is conducting a
good faith and diligent defense at its own expense; provided, however, that the
assumption of defense of any such matters by the indemnifying party shall relate
solely to the claim, liability or expense that is subject or potentially subject
to indemnification.  The indemnifying party shall have the right, with the
consent of the indemnified party, which consent shall not be unreasonably
withheld, to settle all indemnifiable matters related to claims by third parties
which are susceptible to being settled provided the indemnifying parties'
obligation to indemnify the indemnified party therefor will be fully satisfied
subject to the limits set forth herein.  The indemnifying party shall keep the
indemnified party apprised of the status of the claim, liability or expense and
any resulting suit, proceeding or enforcement action, shall furnish the
indemnified party with all documents and information that the indemnified party
shall reasonably request and shall consult with the indemnified party prior to
acting on major matters, including settlement discussions.  Notwithstanding
anything herein stated, the indemnified party shall at all times have the right
to fully participate in such defense at its own expense directly or through
counsel; provided, however, if the named parties to the action or proceeding
include both the indemnifying party and the indemnified party and representation
of both parties by the same counsel would be inappropriate under applicable
standards of professional conduct, the expense of separate counsel for the
indemnified party shall be paid by the indemnifying party.  If no such notice of
intent to dispute and defend is given by the 

                                       39
<PAGE>
 
indemnifying party, or if such diligent good faith defense is not being or
ceases to be conducted, the indemnified party shall, at the expense of the
indemnifying party, undertake the defense of (with counsel selected by the
indemnified party), and shall have the right to compromise or settle (exercising
reasonable business judgment), such claim, liability or expense. If such claim,
liability or expense is one that by its nature cannot be defended solely by the
indemnifying party, then the indemnified party shall make available all
information and assistance that the indemnifying party may reasonably request
and shall cooperate with the indemnifying party in such defense.

          (c) Non-Third Party Claims.  With respect to non-third party claims,
              ----------------------                                          
if within twenty (20) days after receiving the notice described in clause (a)
above the indemnifying party does not give written notice to the indemnified
party that it contests such indemnity, the amount of indemnity payable for such
claim shall be as set forth in the indemnified party's notice, subject to the
limits set forth herein.  If the indemnifying party provides written notice to
the indemnified party within such 20-day period that it contests such indemnity,
the parties shall attempt in good faith to reach an agreement with regard
thereto within thirty (30) days of delivery of the indemnifying party's notice.
If the parties cannot reach agreement within such 30-day period, the matter may
be submitted by either party for binding arbitration in accordance with the
provisions of Section 12.10 hereof.

SECTION 11.  NOTICES.  All notices and other communications required to be given
hereunder, or which may be given pursuant or relative to the provisions hereof,
shall be in writing and shall be deemed to have been given when delivered in
hand or by an overnight courier service, or mailed, postage prepaid, by first
class United States mail, certified return receipt requested, or transmitted by
facsimile (with transmission acknowledgment received, provided written notice
delivered by any of the other means of delivery specified in this Section 11
follows such facsimile), as follows:

Agreement or the breach, termination or validity hereof shall be finally settled
by arbitration conducted expeditiously in accordance with the Center for Public
Resources Rules for Nonadministered Arbitration of Business Disputes (the "CPR
Rules").  The Center for Public Resources shall appoint a neutral advisor from
its National CPR Panel.  The arbitration shall be governed by the United States
Arbitration Act, 9 U.S.C. (S)(S)1-16, and judgment upon the award rendered by
the arbitrators may be entered by any court having jurisdiction thereof.  The
place of arbitration shall be Chicago, Illinois.

     Such proceedings shall be administered by the neutral advisor in accordance
with the CPR Rules as he/she deems appropriate, however, such proceedings shall
be guided by the following agreed upon procedures:

           (a) Mandatory exchange of all relevant documents, to be accomplished
within forty-five (45) days of the initiation of the procedure;

                                       42
<PAGE>
 
          (b) No other discovery;

          (c) Hearings before the neutral advisor which shall consist of a
summary presentation by each side of not more than three hours; such hearings to
take place in one or two days at a maximum; and

          (d) Decision to be rendered not later than ten (10) days following
such hearings.

     Each of the parties hereto (a) hereby unconditionally and irrevocably
submits to the jurisdiction of any United States District Court of competent
jurisdiction located in the State of Michigan for the purpose of enforcing the
award or decision in any such proceeding and (b) hereby waives, and agrees not
to assert in any civil action to enforce the award, any claim that it is not
subject personally to the jurisdiction of the above-named court, that its
property is exempt or immune from attachment or execution, that the civil action
is brought in an inconvenient forum, that the venue of the civil action is
improper or that this Agreement or the subject matter hereof may not be enforced
in or by such court, and (c) hereby waives and agrees not to seek any review by
any court of any other jurisdiction which may be called upon to grant an
enforcement of the judgment of any such court.  Each of the parties hereto
hereby consents to service of process by registered mail at the address to which
notices are to be given.  Each of the parties hereto agrees that its submission
to jurisdiction and its consent to service of process by mail is made for the
express benefit of the other parties hereto.  Final judgment against any party
hereto in any such action, suit or proceeding may be enforced in other
jurisdictions by suit, action or proceeding on the judgment, or in any other
manner provided by or pursuant to the laws of such other jurisdiction; provided,
                                                                       -------- 
however, that any party may at its option bring suit, or institute other
-------                                                                 
judicial proceedings, in any state or federal court of the United States or of
any country or place where the other parties or their assets, may be found.

     Notwithstanding the foregoing, it is specifically understood and agreed
that certain breaches of this Agreement will result in irreparable injury to the
parties hereto, that the remedies available to the parties at law alone will be
an inadequate remedy for such breach, and that, in addition to any other legal
or equitable remedies which the parties may have, a party may enforce its rights
by an action for specific performance and the parties expressly waive the
defense that a remedy in damages will be adequate.
