Section 2.1     Sale and Transfer.

        A. The Sale. Subject to the terms and conditions set forth in this
Agreement, Seller shall sell, convey, transfer, assign and deliver to Buyer, and
Buyer shall purchase and receive from Seller, at the Closing, free and clear of
all Encumbrances, all of the Subject Assets.

Section 2.2     Purchase Price; Assumption of Certain Obligations.

        A. Purchase Price. The Purchase Price to be paid by Buyer for all the
Subject Assets shall be Twenty Million Two Hundred Twelve Thousand Five Hundred
Dollars ($20,212,500) (the "Initial Payment"), plus two contingent payments in
the maximum amount of Two Million Dollars ($2,000,000) each (the "Contingent
Payments"), payable under the circumstances described in Section 2.2.C. The
aggregate of the Initial Payment and the Contingent Payments, adjusted as
provided in Sections 2.2.E, is hereinafter referred to as the "Purchase Price",
and shall be paid in United States currency.

        B. Payment of Purchase Price. The Initial Payment shall be payable to
Seller at the Closing by wire transfer of immediately available funds to such
account as Seller shall designate in writing not less than two business days
prior to the Closing Date.

        C. Contingent Payments. The two Contingent Payments shall be payable by
Purchaser, if at all, as follows:

                (i) The 1997 Contingent Payment shall be payable on February 28,
1998 if Eligible Revenues (as hereinafter defined) during calendar year 1997
("1997 Eligible Revenues") are at least $8,731,000; no 1997 Contingent Payment
shall be payable if 1997 Eligible Revenues are less than $8,731,000. If 1997
Eligible Revenues are $8,731,000, the 1997 Contingent Payment shall be One
Dollar ($1.00); and if 1997 Eligible Revenues are at least $9,582,000, the 1997
Contingent Payment shall be Two Million Dollars. If 1997 Eligible Revenues are
greater than $8,731,000 but less than $9,582,000, the 1997 Contingent Payment
shall be $1.00 plus $2.35 for each dollar of 1997 Eligible Revenues in excess of
$8,731,000. In no event shall the 1997 Contingent Payment exceed $2,000,000.

                (ii) The 1998 Contingent Payment shall be payable on February
28, 1999 if Eligible Revenues during calendar year 1998 ("1998 Eligible
Revenues") are at least $9,604,000; no Contingent Payment shall be payable if
1998 Eligible Revenues are less than $9,604,000. If 1998 Eligible Revenues are
$9,604,000, the 1998 Contingent Payment shall be One Dollar ($1.00); and if 1998
Eligible Revenues are at least $10,540,00, the 1998 Contingent Payment shall be
Two Million Dollars ($2,000,000). If 1998 Eligible Revenues are greater than
$9,604,000, but less than $10,540,000, the 1998 Contingent Payment shall be
$1.00 plus $2.14 for each dollar of 1998 Eligible Revenues in excess of
$9,604,000. The 1998 Contingent Payment shall not exceed $2,000,000; provided,
that if Seller earned only a portion of the maximum 1997 Contingent Payment, but
earns the maximum 1998 Contingent Payment, Buyer shall pay Seller the unpaid
portion of the maximum 1997 Contingent Payment on January 31, 1999.




                (iii) For purposes of this section, "Eligible Revenues" means
revenues of the Business from storage and service of records, but excluding
revenues derived from destructions and sales of recyclable materials. Eligible
Revenues shall be determined using accounting practices and policies consistent
with those used by Seller to determine such revenues in 1996 prior to the
Closing. Eligible Revenues shall not include revenues from customers of any
other records management service provider in the Minneapolis area acquired by
Buyer.

                (iv) Seller (or, in the event Seller has been dissolved, one of
the Stockholders appointed by the other Stockholders) or its representative
shall have the right to examine the books and records of Buyer to audit the
determination of Eligible Revenues reported by Buyer in respect of 1997 and
1998. Such examination in respect of each year shall be commenced not later than
the June 30 next following the date upon which a Contingent is paid or to be
paid, and shall be conducted during normal business hours upon reasonable notice
to Buyer. Buyer shall give Seller reasonable access to its relevant books and
records for purposes of such examination. Any such examination shall be
conducted in such a manner as not to interfere unreasonably with the business or
operations of Buyer and shall be completed within 90 days of its commencement,
and any information provided to Seller during such examination shall be subject
to Section 5.2 hereof. Any dispute arising from such examination shall be
settled by arbitration in accordance with Section 11.5.

        D. Limited Assumption of Contracts and Obligations. Buyer shall assume
no obligations or liabilities of Seller other than the following. Buyer shall
assume and perform:

                (i) all obligations of Seller arising or accruing after the
Effective Time in respect of Seller's contracts, agreements and arrangements
with its customers providing for storage of business records at customary rates;

                (ii) Seller's obligations under the equipment leases listed on
Schedule 3.5 which relate or are properly accruable to periods after the
Effective Time; and.

                (iii) If and to the extent Buyer employs Seller's employees,
Buyer shall assume Seller's obligations under employment agreements, provided
that Seller has disclosed to Buyer all such employment agreements, and further
provided that Buyer shall have the right to negotiate with Seller's former
employees to amend any such employment terms or, if no agreement can be reached,
terminate the employment of any such employees.

        E. Seller to Pay Pre-Closing Expenses; Purchase Price Adjustments.

                (i) Seller shall be responsible for and pay when due all costs
and expenses of operating the Business accrued or accruable prior to the
Effective Time.

                (ii) With respect to ongoing expenses the billing period for
which extends across the Closing Date, Buyer and Seller shall make Closing Date
adjustments to the Purchase Price so that Seller bears the costs of operating
the Business properly accruable under generally accepted accounting principles
("GAAP") in respect of the period prior to the Closing Date and Buyer bears the
cost thereof properly accruable under GAAP in respect of the period commencing
on the Closing Date and thereafter.




                (iii) Buyer shall receive a credit against the Purchase Price
for storage and services to be performed after the Closing Date for which Seller
has received payment prior to the Closing Date.

                (iv) The Purchase Price shall be increased by an amount equal to
the sum of all advances made by Seller prior to the Closing which have not been
reimbursed to Seller as of that date. For purposes of this section, "advances"
shall mean any amounts paid by Seller for the benefit of or on behalf of a
customer which, in the ordinary course, is reimbursable to Seller by such
customer (for example, freight or delivery charges). Seller shall prepare and
deliver to Buyer at or prior to Closing a list of all advances outstanding as of
that date together with such documentation as is necessary to collect
reimbursement therefor from the relevant customer.

                (v) In the event that Seller's accounts receivable as of the
Closing Date (excluding customary levels of doubtful accounts) aggregate less
than $700,000, the Purchase Price shall be reduced by the shortfall between such
amount and the actual amount as of the Closing Date; provided, that Seller's
account receivables from National Records Center Consortium ("NRCC") shall in no
event be deemed a doubtful account even if NRCC should take the position it
refuses to pay such amount.

Section 2.3 Allocation. The Purchase Price shall be allocated among the Subject
Assets as set forth on Schedule 2.3, and the parties shall report the
transactions contemplated hereby in a manner consistent with such allocation for
tax purposes.

Section 2.4 Seller's Employees. Buyer intends to offer employment to all of
Seller's employees; provided that Buyer shall not be obligated to offer
employment to any employee of Seller in connection with the acquisition of the
Subject Assets, and such acquisition shall not grant any employee of Seller a
right of continued employment with Buyer. Any of Seller's employees offered
employment by Buyer shall be employed on substantially the same terms as their
employment with Seller. For a period of one year after the Closing Date, Seller
shall not offer conflicting employment to any person who accepts employment with
Buyer.

Section 2.5 Post-Closing Adjustment Date. Buyer and Seller shall make all
proration adjustments and payments arising under Sections 2.2E, to the extent
known, on the Closing Date. On January 15, 1997, Buyer and Seller shall make any
additional net adjustment by payment of one to the other to effect a final
adjustment in the Purchase Price. If any adjustments are at that date not
determined, Buyer and Seller shall agree in a writing as to the date and method
of settlement of such undetermined amounts.

Section 2.6     Escrow Agreement.

                (a) On or prior to the date of this Agreement, Buyer and Seller
have executed an Escrow Agreement with the law firm of Siegel, Brill, Greupner &
Duffy, P. A., Minneapolis, Minnesota, as escrow agent (the "Escrow Agent").
Within one business day after this Agreement has been executed, Buyer shall
deliver to the Escrow Agent the sum of One Million Dollars (the "Escrow
Deposit") to be held in escrow pursuant to the terms hereof.

                (b) In the event Buyer fails to close the transactions
contemplated by this Agreement after public disclosure of this transaction
(whether by inclusion of information concerning 





this transaction in the Registration Statement described in Section 5.2(b),
publication with respect to any filing in respect of this transaction under the
HSR Act (as hereinafter defined) in the Federal register, or otherwise) on or
before the Closing Date, for any reason other than (i) Seller's inability or
refusal to deliver title to the Subject Assets free and clear of Encumbrances,
(ii) Seller's inability or refusal to deliver evidence that the transactions
were properly authorized by Seller, (iii) the failure or refusal of the
landlords to execute and deliver under the leases described in Section 6.4, or
(iv) the failure or refusal of one or more persons to execute the Noncompetition
and Confidentiality Agreements described in Section 6.3, the Escrow Agent shall
pay the Escrow Deposit, together with interest earned thereon, to Seller as
liquidated damages. Except as provided in the preceding sentence, Buyer waives
any and all of the conditions precedent to its obligation to close, whether set
forth in Article VI or otherwise, the satisfaction of which is required prior to
Seller's right to receive the Escrow Deposit; and payment of the Escrow Deposit
shall be made hereunder without regard to Buyer's termination of, or right to
terminate, this Agreement. Notwithstanding the foregoing, in the event that
Buyer has not received notification of clearance under the HSR Act by November
1, 1996, Buyer may elect by written notice to Seller to extend the Closing Date
to December 1, 1996, and in such event the Escrow Deposit shall continue to be
held in escrow pursuant to the terms hereof until the earlier of the Closing or
such date.

                (c) It is agreed and understood that the Escrow Deposit is
intended to compensate Seller for any damages which it may sustain as a result
of Buyer's public disclosure of this transaction, as provided in 2.6(b) above,
without regard to whether there are demonstrable damages. The right of Seller to
retain the Escrow Deposit hereunder is independent of and in addition to such
rights and remedies as Seller may have at law or in equity or otherwise for
Buyer's failure or refusal to close the transactions contemplated by this
Agreement, none of which rights or remedies shall be affected or diminished
hereby; provided that Seller shall not be entitled to damages in excess of the
Escrow Deposit unless Seller shall have satisfied, or shall have been in a
position to satisfy, all of the conditions to Buyer's obligations to close in
Article VI on or prior to the Closing Date.



                    (ARTICLE III COMMENCES ON THE NEXT PAGE)

Section 3.3 Compliance With Other Instruments. Neither the execution and
delivery by Seller of this Agreement and the Seller's Documents, nor the
consummation by Seller of the transactions contemplated hereby and thereby,

contrary to or violate, breach, or constitute a default under, or permit the
termination or acceleration of maturity of, or result in the imposition of any
lien, claim or encumbrance upon any property or asset of Seller pursuant to any
provision of, any note, bond, indenture, mortgage, deed of trust, evidence of
indebtedness or lease agreement, other agreement or instrument or any judgment,
order, injunction or decree by which Seller is bound, to which either is a
party, or to which the assets of Seller is subject and which will continue in

Section 3.6     Contracts and Other Interests.

contracts (including all customer contracts) are in full force and effect, valid
and enforceable in accordance with their respective terms against Seller and, to
Seller's knowledge, against the other parties thereto, and there are no existing
defaults of Seller or events of default that, with the giving of notice or lapse

or its contract with each such customer to Buyer.

                (d) Seller has no oral agreements with customers which require

knowledge, threatened against Seller in respect of the Subject Assets or the
Business. Except as set forth on Schedule 3.8, during the past six months Seller
has not received any material written assertions from customers of the Business
to the effect that their materials stored with Seller have been lost, damaged or
inappropriately destroyed or that such customers are being billed inaccurately
for storage of materials or records. Seller is not in default with respect to
any currently effective judgment, order, writ, injunction, decree, demand or
assessment issued by any court or of any federal, state, municipal or other
governmental agency, board, commission, bureau, instrumentality or department
and applicable to Seller. Seller is not charged or to Seller's knowledge

responsibilities place them in a position to be aware of such 






matters) threatened with or under investigation with respect to, any violation
of any provision of any federal, state, municipal or other law or administrative
rule or regulation with respect to the Subject Assets or the Business.

Section 3.9 Compliance with Laws. Seller has complied, and through the Closing
will continue to comply, in all material respects with federal, state and local
laws, rules and regulations applicable to the Business and the Subject Assets.
Seller possesses such certificates, authorities or permits issued by the
appropriate local, state or federal regulatory agencies or bodies as are
necessary to conduct the Business in all material respects, all of which are
listed on Schedule 3.9; and Seller has not received any written notice of
proceedings relating to the revocation or modification of any such certificate,
authority or permit. Seller shall not be liable, however, for any assertion by
governmental authorities that the transfer of the Subject Assets pursuant to
this Agreement gives rise to a right on the part of governmental authorities to
apply regulations or ordinances to the Subject Assets which were previously not
applicable because the relevant regulation or ordinance was adopted after the
Subject Asset was constructed or acquired.

Section 3.10 Certain Environmental Matters. Seller is operating and has operated
the Business in the Leased Premises in material compliance with all applicable
local, state and federal environmental laws, regulations and ordinances,
including, but not limited to, the Comprehensive Environmental Response,
Compensation, and Liability Act, 42 U.S.C. ss.ss.9601 et seq. ("CERCLA"), the
Resource Conservation and Recovery Act, 42 U.S.C. ss.ss.6901 et seq., the Clean
Water Act, 33 U.S.C. ss.ss.1251 et seq., and the environmental laws and
regulations of the State of Minnesota as such statute or regulation has been

knowingly accepted for storage, and to the best of its knowledge does not store,
any nitrate film or any hazardous substance or hazardous material in the Leased
Premises except for de minimis amounts used in the ordinary course of business.
Seller has never knowingly caused the release from the Leased Premises of an
amount of any hazardous substance or hazardous material into the environment
which release would constitute a material violation of any Environmental Laws
and Regulations. For purposes of this paragraph, "hazardous substance",
"release" and "environment" shall have the same meanings as those terms are
defined by Section 101 of CERCLA, 42 U.S.C. ss.9601, and "hazardous material"
shall have the same meaning as those terms are defined by Environmental Laws and
Regulations. Seller does not own, lease, rent or otherwise utilize any
underground storage tanks in connection with the Business, and, to the best of
Seller's knowledge, there are no waste tanks, containers, cylinders, drums or
cans buried, stored or deposited in or at the Leased Premises. To the best of
Seller's knowledge (without having conducted an investigation), the Leased
Premises do not contain (i) any asbestos, (ii) any polychlorinated biphenyl

Seller's annual income and expense statement and balance sheet for the years
ended December 31, 1995 and 1994 and for the six months ended June 30, 1996 (the
"Financial Statements"). The Financial Statements are true, correct and complete
in all material respects for the periods covered and fairly present the results
of operation of the Business for the periods covered. The Financial Statements
for the years ended 





December 31, 1995 and 1994 were prepared pursuant to GAAP; the Financial
Statements for the six months ended June 30, 1996 were prepared on a basis
consistent with the Financial Statements for the year ended December 31, 1995,
except for accruals normally performed at year-end, such as bonuses and
profit-sharing, and other customary year-end adjustments and other adjustments
required by GAAP.

Section 3.13 ERISA Plans. Schedule 3.13 lists the Employee Pension Benefit Plans
or Employee Welfare Benefit Plans, as each term is defined in the Employee
Retirement Income Security Act of 1974, maintained by Seller for the employees

since January 1, 1996, none of Seller's customers whose business averaged in
excess of $1,000 per month for the six months ending June 30, 1996 has
terminated or indicated in writing (or, to the best of Seller's knowledge,
orally) an intention to terminate its business with, or reduce the volume of its
business with, Seller. Except as otherwise stated in Schedule 3.15, to Seller's
knowledge (without investigation other than inquiry of employees of Seller whose
responsibilities place them in a position to be aware of such matters), Seller
has no customers whose storage business is or has within 90 days prior to the
date of this Agreement been the subject of competitive bidding procedures.

Section 3.16 No Material Undisclosed Liabilities. Except as described in this
Agreement or reflected in the Financial Statements, there is no liability or
obligation of Seller related to the operation of the Business, whether accrued,
absolute or contingent, other than liabilities and obligations that have been
incurred in the ordinary course of business consistent with past practice since
June 30, 1996 and are not material in the aggregate to the Business.

Section 3.17 Personnel Information. Schedule 3.17 lists the names of all full-
and part-time employees of Seller (or leased employees utilized by Seller) who
perform services for the Business and sets forth a brief job description or
title and compensation for each such person. Schedule 3.17 also sets forth a
list of all written and oral employment and noncompetition agreements with
Seller's employees employed in the Business.

Section 3.18 Patents, Trademarks, Etc. Except for the trade names "Mohawk

programs or programs rights, patents, licenses or other similar intangible
property rights and interests which it uses in connection with the Business.

Section 3.19 Labor Relations. During the past three years there has not been,
and there is not now, any strike, labor dispute, slow down, stoppage, or other
material interference with or impairment by labor of the business of Seller
pending or, to the knowledge of Seller (without investigation), threatened or
contemplated against or directly affecting the Business. Seller's employees are
not represented by any labor or trade union, nor, to the knowledge of Seller,
has there been any attempt to organize Seller's employees during the two-year
period prior to the date hereof.




Section 3.20 Insurance. There is in force comprehensive general liability and
casualty insurance for the Subject Assets and the Business which, in the
reasonable opinion of Seller, is appropriate and adequate coverage for such
assets and operations.

Section 3.21 Trade Secrets and Customer Lists. Seller has received no written
claims challenging its right to use any trade secrets, customer lists,
intellectual property and operating methods required for or incident to the
operation of the Business. To the best of its knowledge (without investigation),
Seller is not using or in any way making use of any confidential information or
trade secrets of any third party, including without limitation, a former
employer of any present or past employee or Seller.

records received for filing or refiling more than five business days prior to
the date hereof. Seller has completed all destructions and other inventory and
special-service projects for which Seller has received payment.

change in the Subject Assets (including, without limitation, loss of or damage
to a material amount or part of the Subject Assets) or the results of operation
(including operating cash flow), other than possible industry-wide changes, as
to which Seller makes no representation, between June 30, 1996 and the date

Seller's affairs or the Business, at Buyer's customary fees therefor. If Seller
notifies Buyer that Seller requires retention of such records beyond four years,
Seller shall have the right to take such records or pay Buyer's customary
storage charges for such post-four-year period.

Seller shall, for at least two years after the Closing Date, retain copies of
all records of the Business retained by Seller, and shall grant access thereto
to Buyer upon reasonable request.

Section 9.2 Public Announcement. Except as provided in Section 5.2(b), no party
shall issue any press release or make any public announcement relating to the
subject matter of this Agreement without the prior written approval of the other
party; provided, however, that after the Closing the parties may (i) make
appropriate announcements to customers of the Business, and (ii) make a public
announcement to the effect that the transaction has occurred (without any
financial information), each after consultation with, and approval of, the other
party; and provided further that either party may make any public disclosure it
believes in good faith is required by applicable law or any listing or trading
agreement concerning its publicly-traded securities.

Section 9.3 Right of First Refusal. In the event that during the five-year
period commencing with the Closing Date Buyer receives an offer to purchase the
Business which Buyer intends to accept, Buyer shall so notify Seller in writing
within ten (10) days after determination to accept such offer. Seller shall have
fifteen (15) business days in which to deliver notice to Buyer that Seller
elects to purchase the Business at the same price and upon the same terms as
described in Buyer's notice, and Seller shall thereupon have the right and
obligation to purchase the Business for such price and upon such terms. If
Seller fails to exercise this right of first refusal within said period, Buyer
may at any time thereafter within 180 days after the end of the fifteen-day
period sell the Business upon the same or substantially similar terms and at the
same price or within three percent thereof and this right of first refusal shall
terminate upon any such sale. If the proposed sale of the Business is not
consummated within the 180 day period, Seller shall again have a right of first
refusal in connection with any offer which Buyer intends to accept. This right
of first refusal shall not be exercisable by Seller upon a transfer by Buyer of
the Business to any corporation, trust, partnership or other entity controlling,
controlled by or under common control with Buyer, nor shall it apply to any sale
of the Business together with other records storage businesses of Buyer as a
single or integrated transaction, but this right of first refusal shall survive
such transfer. This right of first offer may be exercised by Seller or any
person designated by Seller.

                                  TERMINATION


Section 10.1 Termination of Agreement. The parties may terminate this Agreement
as provided below:

                      (i) Buyer and Seller may terminate this Agreement by
mutual written consent at any time prior to the Closing;

                      (ii) Buyer may terminate this Agreement by giving written
notice to Seller at any time prior to the Closing (A) in the event Seller has
breached any material representation, warranty, or covenant contained in this
Agreement in any material respect, Buyer has notified Seller of the breach, and
the breach has continued without cure for a period of 20 days after the notice
of breach or (B) if the Closing shall not have occurred on or before December
31, 1996, by reason of the failure of any condition precedent under Article VI
hereof (unless the failure results primarily from Buyer itself breaching any
representation, warranty, or covenant contained in this Agreement); and

                      (iii) Seller may terminate this Agreement by giving
written notice to Buyer at any time prior to the Closing (A) in the event Buyer
has breached any material representation, warranty, or covenant contained in
this Agreement in any material respect, Seller has notified Buyer of the breach,
and the breach has continued without cure for a period of 20 days after the
notice of breach or (B) if the Closing shall not have occurred on or before
December 31, 1996, by reason of the failure of any condition precedent under
Article VII hereof (unless the failure results primarily from Seller itself
breaching any representation, warranty, or covenant contained in this
Agreement).

Section 10.2 Effect of Termination. If either party terminates this Agreement
pursuant to Section 10.1, all rights and obligations of the parties hereunder,
other than the confidentiality obligation set forth in Section 5.2, shall
terminate without any liability of any party to any other party (except for any
liability of any party then in breach). In addition, if the Agreement is
terminated and the transactions contemplated hereby are not completed by
December 31, 1996 because of the failure or inability of Seller to satisfy the
four conditions set forth in Section 2.6(b), Buyer shall be entitled to return
of the Escrow Deposit together with interest earned thereon.

Section 10.3 Risk of Loss. Prior to Closing the risk of loss, damage or
destruction with respect to the Subject Assets shall be borne solely by Seller.
If at the Closing Date the Subject Assets shall have suffered loss, damage or
destruction to an extent which materially affects the value thereof, and such
loss is not adequately covered by insurance or materially impairs Seller's
ability to conduct the Business, Buyer shall have the right at its election to
terminate this Agreement, or complete the transactions with such adjustment of
the Purchase Price as may be agreed in good faith between Buyer and Seller.

                                INDEMNIFICATION

Section 11.1 General Indemnification Obligation of Seller and Stockholders. From
and after the Closing, Seller and Stockholders shall reimburse, indemnify and
hold harmless Buyer and its successors and assigns (each an "Indemnified Buyer
Party") against and in respect of:

                (a) any and all damages (excluding consequential damages, lost
profits, lost business opportunities and incidental damages), losses,
deficiencies, liabilities, costs and expenses (including assessments, legal
fees, litigation costs, fines and judgments) incurred or suffered by any
Indemnified Buyer Party that result from, relate to or arise out of:

                      (i) any and all liabilities and obligations of Seller of
any nature whatsoever (including liabilities for Taxes) arising from or incurred
in the operation of the Business prior to the Closing Date, except for those
liabilities and obligations of Seller which Buyer specifically assumes pursuant
to this Agreement;

                      (ii) other than as described at (iii) below, any and all
actions, suits, claims or legal, administrative, arbitration, governmental or
other proceedings or investigations against any Indemnified Buyer Party to the
extent relating to Seller or the Business to the extent (and only to the extent)
the reason therefor or subject thereof arose or occurred prior to the Closing
Date or which result from or arise out of any action or inaction prior to the
Closing Date of Seller or any director, officer, employee, agent, representative
or subcontractor of Seller, except for those which Buyer specifically assumes
pursuant to this Agreement;

                      (iii) any cost, claim, expense or liability (including
legal fees and costs of litigation) which Buyer may incur or with which Buyer
may be threatened in writing by a customer in excess of $2.00 per carton, linear
foot of open-shelf files, disk pack or other storage unit in connection with
lost, damaged or destroyed records of customers with which Seller did not, as of
the Closing Date, have a contract which limited Seller's liability in the event
of loss, damage or destruction to such amount, provided that Seller shall not be
required to indemnify Buyer in respect of any loss, damage or destruction which
(i) relates to new cartons moved into the Leased Premises after the Closing
Date, (ii) Seller is able to demonstrate occurred after the Closing Date or
(iii) occurs after Buyer has picked up, retrieved, moved or otherwise physically
dealt with a lost, damaged or destroyed carton; and

                      (iv) any material misrepresentation, breach of warranty or
nonfulfillment of any agreement or covenant on the part of Seller under this
Agreement, or any material misrepresentation in or omission from any
certificate, schedule, statement, document or instrument furnished to Buyer at
the Closing pursuant hereto.

                (b) The liability of the Stockholders hereunder shall be several
and not joint. Each Stockholder's liability in respect of any claims hereunder
shall be that proportionate share of the claim equal to the percentage of all
the issued and outstanding stock of Seller owned by such Stockholder on the date
hereof.

                Notwithstanding anything herein contained to the contrary,
Seller and Stockholder shall have no obligations to Buyer under Section 11.1
with respect to any claim of which Buyer gives notice to Seller or Stockholder
later than the last day of the twelfth month after the Closing Date, 





except with respect to (i) federal, state and local taxes where the applicable
statute of limitations exceeds twelve months, in which case notice must be given
not later than thirty (30) days following the expiration of the relevant statute
of limitations, and (ii) claims related to consensual liens affecting the
Subject Assets, with respect to which notice of claims may be given at any time
within ninety days after such liens are discovered by Buyer.

                Notwithstanding any other provision herein contained, Seller and
Stockholders shall not have any indemnification obligation with respect to the
first $50,000 of total claims incurred under Section 11.1. In no event shall
Seller's or Stockholders' indemnification obligation exceed the sum of
$1,500,000, provided that there shall be no limit on indemnification obligations
related to taxes or consensual liens affecting the Subject Assets.

                In case any event shall occur which would otherwise entitle
either party to assert a claim for indemnification hereunder, no loss shall be
deemed to have been sustained by such party to the extent of (i) any tax savings
realized by such party with respect thereto, or (ii) any after-tax proceeds
received by such party from any third party, including but not limited to any
insurance carrier.

Section 11.2 General Indemnification Obligation of Buyer. From and after the
Closing, Buyer will reimburse, indemnify and hold harmless Seller and
Stockholders and their successors or assigns (an "Indemnified Seller Party")
against and in respect of:

                (a) any and all damages (excluding consequential damages, lost
profits, lost business opportunities and incidental damages), losses,
deficiencies, liabilities, costs and expenses (including assessments, legal
fees, litigation costs, fines and judgments) incurred or suffered by any
Indemnified Seller Party that result from, relate to or arise out of:

                      (i) any and all liabilities and obligations of Seller
which have been specifically assumed by Buyer pursuant to this Agreement;

                      (ii) any and all liabilities and obligations arising from
or incurred in the operation of the Business after the Closing Date;

                      (iii) any and all actions, suits, claims or legal,
administrative, arbitration, governmental or other proceedings or investigations
against any Indemnified Seller Party to the extent relating to Buyer or the
Business to the extent (and only to the extent) the reason therefor or subject
thereof arose or occurred after the Closing Date or which result from or arise
out of any action or inaction after the Closing Date of Buyer or any director,
officer, employee, agent, representative or subcontractor of Buyer; and

                      (iv) any material misrepresentation, breach of warranty or
non-fulfillment of any agreement or covenant on the part of Buyer under this
Agreement, or any material misrepresentation in or omission from any
certificate, schedule, statement, document or instrument furnished to Seller
pursuant hereto or in connection with the negotiation, execution or performance
of this Agreement.

                Notwithstanding anything herein contained to the contrary, Buyer
shall have no obligations to Seller or Stockholders under Section 11.2(a)(iv)
with respect to any claim of which Seller gives notice to Buyer later than the
last day of the twelfth month after the Closing Date.




                In case any event shall occur which would otherwise entitle
either party to assert a claim for indemnification hereunder, no loss shall be
deemed to have been sustained by such party to the extent of (i) any tax savings
realized by such party with respect thereto, or (ii) any after-tax proceeds
received by such party from any third party, including but not limited to any
insurance carrier.

Section 11.3 Method of Asserting Claims, Etc. In the event that any claim or
demand for which Seller or Stockholders (the "Indemnifying Party") would be
liable to an Indemnified Buyer Party hereunder is asserted against or sought to
be collected from an Indemnified Buyer Party by a third party, the Indemnified
Buyer Party shall promptly notify Seller of such claim or demand, specifying the
nature of such claim or demand and the amount or the estimated amount thereof to
the extent then feasible, which estimate shall not be conclusive of the final
amount of such claim and demand (the "Claim Notice"). Indemnifying Party shall
have thirty days from the personal delivery or mailing of the Claim Notice (the
"Notice Period") to notify the Indemnified Buyer Party (A) whether or not it
disputes its liability to the Indemnified Buyer Party hereunder with respect to
such claim or demand and (B) notwithstanding any such dispute, whether or not it
desires, at its sole cost and expense, to defend the Indemnified Buyer Party
against any such claim or demand.

                (a) If Indemnifying Party disputes its obligation to indemnify
Buyer with respect to such claim or demand or the amount thereof (whether or not
Indemnifying Party desires to defend the Indemnified Buyer Party against such
claim or demand as provided in paragraphs (b) and (c) below), such dispute shall
be resolved in accordance with Section 11.5 hereof. Pending the resolution of
any dispute by Indemnifying Party of its liability with respect to any claim or
demand, such claim or demand shall not be settled without the prior written
consent of both Buyer and Seller, which consent shall not be unreasonably
withheld or delayed.

                (b) In the event that Indemnifying Party notifies the
Indemnified Buyer Party within the Notice Period that it desires to defend the
Indemnified Buyer Party against such claim or demand then, except as hereinafter
provided, Indemnifying Party shall have the right to defend the Indemnified
Buyer Party, at the Indemnifying Party's sole cost and expense, by appropriate
proceedings, which proceedings shall be promptly settled or prosecuted by it to
a final conclusion in such a manner as to avoid any risk of Indemnified Buyer
Party becoming subject to further liability in respect of such matter; provided,
however, Indemnifying Party shall not, without the prior written consent of the
Indemnified Buyer Party (which consent shall not be unreasonably withheld or
delayed), consent to the entry of any judgment against the Indemnified Buyer
Party or enter into any settlement or compromise which does not include, as an
unconditional term thereof, the giving by the claimant or plaintiff to the
Indemnified Buyer Party of a release, in form and substance satisfactory to the
Indemnified Buyer Party, as the case may be, from all liability in respect of
such claim or litigation. If any Indemnified Buyer Party desires to participate
in, but not control, any such defense or settlement, it may do so at its sole
cost and expense.

                (c) (i) If Indemnifying Party elects not to defend the
Indemnified Buyer Party against such claim or demand, whether by not giving the
Indemnified Buyer Party timely notice as provided above or otherwise, then the
amount of any such claim or demand as reduced to judgment or settlement, or if
the same be defended by Indemnifying Party or by the Indemnified Buyer Party
(but none of the Indemnified Buyer Party shall have any obligation to defend any
such claim or demand), then that portion thereof as to which such defense is
unsuccessful, in each case, shall be conclusively deemed to be a liability of
Indemnifying Party hereunder, unless Indemnifying Party shall have disputed 




its liability to the Indemnified Buyer Party hereunder, as provided in (a)
above, in which event such dispute shall be resolved as provided in Section 11.5
hereof.

                      (ii) In the event an Indemnified Buyer Party should have a
claim against Indemnifying Party hereunder that does not involve a claim or
demand being asserted against or sought to be collected from it by a third
party, the Indemnified Buyer Party shall promptly send a Claim Notice with
respect to such claim to Indemnifying Party. If Indemnifying Party disputes its
liability with respect to such claim or demand, such dispute shall be resolved
in accordance with Section 11.5 hereof.

                (d) All claims for indemnification by an Indemnified Seller
Party under this Agreement shall be asserted and resolved under the procedures
set forth above substituting in the appropriate place "Indemnified Seller Party"
for "Indemnified Buyer Party", "Buyer" for "Indemnifying Party" and variations
thereof.

Section 11.4 Payment. Upon the determination of liability under Section 11.3 or
11.5 hereof, the appropriate party shall pay to the other, as the case may be,
within ten days after such determination, the amount of any claim for
indemnification made hereunder. In the event that the indemnified party is not
paid in full for any such claim pursuant to the foregoing provisions promptly
after the other party's obligation to indemnify has been determined in
accordance herewith, it shall have the right, notwithstanding any other rights
that it may have against any other person, firm or corporation, to set off the
unpaid amount of any such claim against any amounts owed by it under any
agreements entered into pursuant to this Agreement. Upon the payment in full of
any claim, either by setoff or otherwise, the entity making payment shall be
subrogated to the rights of the indemnified party against any person, firm or
corporation with respect to the subject matter of such claim.

Section 11.5    Arbitration.

                      (i) All disputes under this Article XI or otherwise
arising under this Agreement shall be settled by arbitration in Minneapolis,
Minnesota, before three arbitrators pursuant to the rules of the American
Arbitration Association. Arbitration may be commenced at any time by any party
hereto giving written notice to each other party to a dispute that such dispute
has been referred to arbitration under this Section 11.5. The arbitrators shall
be selected by the joint agreement of Seller and Buyer, but if they do not so
agree within 20 days after the date of the notice referred to above, the
selection shall be made pursuant to the rules from the panels of arbitrators
maintained by such Association. Any award rendered by the arbitrators shall be
conclusive and binding upon the parties hereto and not subject to appeal;
provided, however, that any such award shall be accompanied by a written opinion
of the arbitrators giving the reasons for the award. This provision for
arbitration shall be specifically enforceable by the parties and the decision of
the arbitrators in accordance herewith shall be final and binding and there
shall be no right of appeal therefrom. In any such action the arbitrators shall
be specifically authorized to award all or a portion of its attorneys' fees and
costs to a prevailing party or to cause such party to bear his or its own fees
and costs.

                      (ii) To the extent that arbitration may not be legally
permitted by applicable law or statute, and the parties to any dispute hereunder
do not at the time of such dispute mutually agree to submit such dispute to
arbitration, any party may commence a civil action in a court of appropriate
jurisdiction to solve disputes hereunder. Nothing contained in this Section 11.5
shall prevent the parties from settling any dispute by mutual agreement at any
time.




Section 11.6 Compliance with Bulk Sales Law. Buyer and Seller hereby waive
compliance by Seller with the bulk sales law and any other similar laws in any
applicable jurisdiction in respect of the transactions contemplated by this
Agreement. Seller and Stockholders shall indemnify Buyer from, and hold it
harmless against, any liabilities, damages, costs and expenses resulting from or
arising out of (i) the parties' failure to comply with any of such laws in
respect of the transactions contemplated by this Agreement, or (ii) any action
brought or levy made as a result thereof, other than those liabilities which
have been expressly assumed, on such terms as expressly assumed, by Buyer
pursuant to this Agreement.

Section 11.7 Other Rights and Remedies Not Affected. Except as otherwise
specifically provided, the indemnification rights of the parties under this
Article XI are such parties' sole rights and remedies under this Agreement and
with respect to disputes arising herefrom, and are in lieu of, and not in
addition to, rights and remedies a party may otherwise have at law or in equity.
