     amounts paid in settlement, losses, expenses, or otherwise and whether such
     indemnification is pursuant to any statute, charter document, bylaw,
     agreement, or otherwise);

          (ix)   all liabilities arising from the operation of any successor
     liability statutes, to the extent that non-compliance therewith or the

following (the "Purchase Price"): 

          (i)    Five Hundred Thousand Dollars ($500,000.00); plus

          (ii)   115,000 shares of common stock of ZEVEX International, Inc.
     (the "Shares"); plus

          (iii)  an amount equal to the estimated actual cost of the Parts

                                       8

<PAGE>

The value of the Shares for purposes of calculating the amount of the Purchase
Price shall be determined based upon the average closing price as quoted on the
American Stock Exchange for the 90-day period ending one day prior to the
Closing Date.

     (f)  PAYMENT AND HOLDBACK.  On the Closing Date, the Buyer shall pay to the
Target all amounts required by Section 2(e) (subject to the holdback described
below) by physical delivery of certificates for the Shares to the Target and by
wire transfer of immediately available funds to such account as the Target shall
designate. The Buyer acknowledges that the Target intends to immediately
transfer the Shares to Elan International Services Ltd. as payment of certain
indebtedness of the Target.  The Buyer shall reserve a portion of the Purchase
Price to be delivered at the Closing to cover any decrease to the Purchase Price
as provided in Section 2(g) below and any payments due the Buyer under Section
6(i) or Section 8(b).  The Parties agree that the Buyer shall withhold ten
Percent (10%) of the Estimated Parts Inventory Amount from the cash portion of
the Purchase Price to be delivered at the Closing and that this amount, less
deductions required to cover such Purchase Price decrease, will be delivered to
the Target on a deferred basis within 10 days following the determination of the
Final Parts Inventory Amount.  The Parties further agree that the Buyer shall
withhold an additional Fifty Thousand Dollars ($50,000) from the cash portion of
the Purchase Price to be delivered at the Closing and that this amount, less
deductions pursuant to Section 6(i) or Section 8(b) will be delivered to the
Target on a deferred basis no later than 180 days following Closing.  Such
reserved funds shall be delivered instead to a mutually agreeable third party
escrow agent, to hold in an interest bearing account, and released to the
respective Parties in accordance with the terms of this Agreement and a mutually
agreed upon escrow agreement to be executed on or prior to Closing.  

     (g)  INVENTORY PROCEDURE AND PURCHASE PRICE ADJUSTMENT.  Promptly following
the Closing Date, the Target shall take a physical inventory of all Parts
Inventory in accordance with procedures to be established by mutual agreement of
Buyer and the Target prior to Closing.  The Buyer shall have the right to have
representatives present during such inventory.  Within thirty (30) days after
the completion of such inventory, the Target shall prepare and deliver to the
Buyer a statement (the "Inventory Statement"), which has been reviewed and
reported on by Buyer's independent auditors in accordance with procedures to be
established by Buyer and the Target, without exception or qualification, setting
forth the actual cost of the Parts Inventory (the "Final Parts Inventory
Amount").  The Purchase Price shall be increased by the amount, if any, by which
the Final Parts Inventory Amount exceeds the Estimated Parts Inventory Amount. 
Conversely, the Purchase Price shall be decreased by the amount, if any, by
which the Final Parts Inventory Amount is less than the Estimated Parts
Inventory Amount.  The Buyer shall pay to the Target any such increase in the
Purchase Price and the Target shall repay to the Buyer any such decrease in the
Purchase Price within thirty (30) days following the determination of the
adjustment pursuant to this Section 2(g).

permission has repudiated any provision thereof;

                 (E)     with respect to each sublicense, to the Knowledge of

proceeding, hearing, investigation, charge, complaint, claim, or demand is
pending or is 

                                       13

<PAGE>

threatened which challenges the legality, validity, or enforceability of the 
underlying item of Intellectual Property; and

                 (H)     the Target has not granted any sublicense or similar
right with respect to the license, sublicense, agreement, or permission.

          (v)    To the Knowledge of the Target, the Division Intellectual
     Property will not interfere with, infringe upon, misappropriate, or
     otherwise come into conflict with, any Intellectual Property rights of
     third parties as a result of the continued operation of the Division's
     businesses as presently conducted and as presently proposed to be
     conducted.

          (vi)   The Target has no Knowledge of any new products, inventions,
     procedures, or methods of manufacturing or processing that any competitors
     or other third parties have developed which reasonably could be expected to
     supersede or make obsolete any product or process of the Division.

     (i)  TANGIBLE ASSETS.  Schedule 2(a)(i) is a true and correct list of the
Fixed Assets which are material to the operation of the Business.  The Target
owns or leases all Fixed Assets and other tangible assets necessary for the
conduct of the businesses of the Division as presently conducted and as
presently proposed to be conducted.  The tangible assets are suitable for the
purposes for which they presently are used and proposed to be used.  The parties
acknowledge that the Fixed Assets are being sold by the Target "as is" without
representation or warranty as to defects, condition, maintenance or repair.

     (j)  INVENTORY.  The General Inventory is merchantable, in good condition,
without material defects, meets all applicable specifications and standards, and
fit for the purpose for which it was procured or manufactured, and none of which
is slow-moving, obsolete or damaged, subject only to the reserve for inventory
writedown set forth on the face of the Most Recent Balance Sheet (rather than in
any notes thereto) as adjusted for the passage of time through the Closing Date
in accordance with the past custom and practice of the Target.  The Target's
finished goods are salable in the Ordinary Course of Business at prices the
Target has charged during the past sixty (60) days.  The Target has on hand or
has ordered and expects timely delivery of such quantities of raw materials and
has on hand such quantities of work in process and finished goods as are
reasonably required to timely fill orders on hand which require delivery with
ninety (90) days.  None of the inventory items necessary to manufacture the
products currently sold by the Division is in short supply or otherwise
difficult to obtain.

respect to each Contract: (A) the agreement is legal, valid, binding,
enforceable, and in full force and effect; (B) the agreement will continue to be
legal, valid, binding, enforceable, and in full force and effect on identical
terms following the 

                                       14

<PAGE>

consummation of the transactions contemplated hereby; (C) no party is in 
breach or default, and no event has occurred which with notice or lapse of 
time would constitute a breach or default, or permit termination, 
modification, or acceleration, under the agreement; and (D) no party has 
repudiated any provision of the agreement.  The Assumed Contracts are or will 
be sufficient to permit Buyer to operate the Business in a manner 
substantially the same as the current operations of the Target.  The 
assignment of the Assumed Contracts to Buyer at Closing pursuant to the terms 
of this Agreement will effectively transfer the Target's interests in the 
Assumed Contracts to Buyer. Nothing in the assignment of the Assumed 
Contracts to Buyer in accordance with the terms of this Agreement shall 
render the Assumed Contracts non-binding, invalid or ineffective, subject to 
the receipt of any required consents to such assignment.  The Target has 
delivered to the Buyer a correct and complete copy of each written agreement 
listed in Section 3(k) of the Disclosure Schedule (as amended to date) and a 
written summary setting forth the terms and conditions of each oral agreement 
referred to in Section 3(k) of the Disclosure Schedule.  

     (l)  LITIGATION.  Section 3(l) of the Disclosure Schedule sets forth each
instance in which the Target (i) is subject to any outstanding injunction,
judgment, order, decree, ruling, or charge or (ii) is a party or is threatened
to be made a party to any action, suit, proceeding, hearing, or investigation
of, in, or before any court or quasi-judicial or administrative agency of any
federal, state, local, or foreign jurisdiction or before any arbitrator.  None
of the actions, suits, proceedings, hearings, and investigations set forth in
Section 3(l) of the Disclosure Schedule could result in any adverse change in
the business, financial condition, operations, results of operations, or future
prospects of the Target or the Division.  The Target has no Knowledge and no
reason to believe that any such action, suit, proceeding, hearing, or
investigation may be brought or threatened against the Target.

     (m)  PRODUCT WARRANTY.  To the Knowledge of the Target, each product
manufactured, sold, leased, or delivered by the Target with respect to the
business of the Division has been in conformity with all applicable contractual
commitments and all express and implied warranties, and the Target does not have
any Liability (and there is no Basis for any present or future action, suit,
proceeding, hearing, investigation, charge, complaint, claim, or demand against
any of them giving rise to any Liability) for replacement or repair thereof or
other damages in connection therewith, subject only to the reserve for product
warranty claims set forth on the face of the Most Recent Balance Sheet (rather
than in any notes thereto) as adjusted for the passage of time through the
Closing Date in accordance with the past custom and practice of the Target.  No
product manufactured, sold, leased, or delivered by the Division is subject to
any guaranty, warranty, or other indemnity beyond the applicable standard terms
and conditions of sale or lease.  Section 3(m) of the Disclosure Schedule
includes copies of the standard terms and conditions of sale or lease for each
of the products of the Division, including Pump Lease Agreements (containing
applicable guaranty, warranty, and indemnity provisions).  

     (n)  CUSTOMERS AND SUPPLIERS.  Section 3(n) of the Disclosure Schedule
lists the 10 largest customers and suppliers of the Division for the fiscal year
ended December 31, 1997, and the six-month period ended June 30, 1998, and
described for each such customer or supplier the approximate percentage of net
sales or purchases by the Division for each such period.  Since

                                       15

June 30, 1998, no customer listed in accordance with the foregoing has 
indicated that it will stop or decrease the rate of business done with the 
Division except for changes in the Ordinary Course of Business. 

     (o)  PRODUCT LIABILITY.  To the Knowledge of the Target, it does not have
any Liability (and there is no Basis for any present or future action, suit,
proceeding, hearing, investigation, charge, complaint, claim, or demand against
any of them giving rise to any Liability) arising out of any injury to
individuals or property as a result of the ownership, possession, or use of any
product manufactured, sold, leased, or delivered by the Division.

     (p)  DISCLOSURE.  The representations and warranties contained in this
Section 3 do not contain any untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements and
information contained in this Section 3 not misleading.

     (q)  INVESTMENT.  The Target (i) understands that the Shares have not been,
and will not be, registered under the Securities Act, or under any state
securities laws, and are being offered and sold in reliance upon federal and
state exemptions for transactions not involving any public offering, (ii) is

that term is defined in Regulation 501 promulgated under the Securities Act,
(vii) the certificates representing the Shares will bear a legend indicating the
Shares may not be transferred unless in compliance with applicable law as
determined by counsel for the Buyer (which the Buyer may enforce by issuing
stop-transfer instructions to its transfer agent).  

     (r)  LICENSES AND PERMITS.  Except as set forth in Section 3(r) of the
Disclosure Schedule, to the Target's Knowledge, the Licenses and Permits
constitute all of the necessary or required permits or licenses or other
governmental authorizations pertaining to or required for the operation of the
Acquired Assets.  To the Knowledge of the Target, the Licenses and Permits are
valid and in full force and effect and, to its Knowledge, the Target has timely
taken all necessary actions to preserve such Licenses and Permits and have not
engaged in any activity or act and will not engage in any activity or act that
has or may jeopardize the validity of or prevent the effective transfer (to the
extent permitted by law) of the Licenses and Permits to Buyer.

     4.   REPRESENTATIONS AND WARRANTIES OF THE BUYER.  The Buyer represents and
warrants to the Target that the statements contained in this Section 4 are
correct and complete as of the date of this Agreement and will be correct and

Buyer is a corporation duly organized, validly existing, and in good standing
under the laws of the jurisdiction of its incorporation.  Buyer is duly
authorized to conduct business and is in good standing under the laws of each
jurisdiction in which the nature of its business or the ownership or leasing of
its properties requires such qualification.  Buyer has full corporate power and
authority to carry on the business in which it is engaged and to own and use the

of any provision of its articles of incorporation or bylaws.

     (b)  AUTHORIZATION OF TRANSACTION.  The Buyer has full power and authority
(including full corporate power and authority) to execute and deliver this
Agreement and to perform its obligations hereunder.  The execution and delivery
of this Agreement and the consummation of the transactions contemplated thereby,
including the issuance of the shares of Buyer, will have been approved by the
board of directors of Buyer as of the Closing Date.  This Agreement constitutes
the valid and legally binding obligation of the Buyer, enforceable in accordance
with its terms and conditions.

     (c)  NONCONTRAVENTION.  Neither the execution and the delivery of this
Agreement, nor the consummation of the transactions contemplated hereby, will
(i) violate any constitution, statute, regulation, rule, injunction, judgment,
order, decree, ruling, charge, or other restriction of any government,
governmental agency, or court to which the Buyer is subject or any provision of
its charter or bylaws or (ii) conflict with, result in a breach of, constitute a
default under, result in the acceleration of, create in any party the right to
accelerate, terminate, modify, or cancel, or require any notice under any
agreement, contract, lease, license, instrument, or other arrangement to which
the Buyer is a party or by which it is bound or to which any of its assets is
subject.  The Buyer does not need to give any notice to, make any filing with,
or obtain any authorization, consent, or approval of any government or
governmental agency in order for the Parties to consummate the transactions
contemplated by this Agreement. 

     (d)  BROKERS' FEES.  The Buyer has no Liability or obligation to pay any
fees or commissions to any broker, finder, or agent with respect to the
transactions contemplated by this Agreement for which the Target could become
liable or obligated.

     5.   PRE-CLOSING COVENANTS.  The Parties agree as follows with respect to
the period between the execution of this Agreement and the Closing.

     (a)  GENERAL.  Each of the Parties will use its best efforts to take all
action and to do all things necessary, proper, or advisable in order to
consummate and make effective the transactions contemplated by this Agreement
(including satisfaction, but not waiver, of the Closing conditions set forth in
Section 7 below).

     (b)  NOTICES AND CONSENTS.  The Target will give any notices to third
parties, and the 

                                       17

<PAGE>

Target will use its reasonable best efforts to obtain any third party 
consents, that the Buyer may request in connection with the transfer of the 
Acquired Assets and assumption of the Assumed Contracts.  Each of the Parties 
will give any notices to, make any filings with, and use its reasonable best 
efforts to obtain any authorizations, consents, and approvals of governments 
and governmental agencies in connection with the matters referred to in 
Section 3(c) and Section 4(c) above, and to obtain the estoppel certificates 
referred to in Section 7(a)(iv) from the parties identified in Schedule 
7(a)(iv).  To the extent that such transfer or assignment shall require such 
consent of any other party in order to permit such transfer, or to avoid any 
indebtedness secured by the Acquired Assets coming due by reason of such 
transfer, this Agreement shall not constitute a contract to transfer the same 
unless and until such consent is obtained.  

     (c)  OPERATION OF BUSINESS.  The Target agrees that in connection with the
operation of the Division from the date hereof until the earlier of the Closing
Date or the termination of this Agreement, except as otherwise consented to or
approved by Buyer in writing:
          
          (i)    The Target shall use best efforts to continue to operate the
     Division in the Ordinary Course of Business, consistent with past
     practices, except for taking such steps as may be necessary or proper to
     carry out and consummate the transactions contemplated by this Agreement. 
     Without limiting the foregoing obligation, and by way of example, the
     Target agrees to use best efforts to: (A) to maintain a level of
     advertising reasonably comparable to that existing during the ninety (90)
     day period immediately preceding the date of this Agreement; (B) to perform
     customary maintenance on the Acquired Assets; (C) not to agree to any
     amendment to any of the Assumed Contracts, or make any agreement affecting
     the Target's use of or interest in the Acquired Assets (except purchase
     orders in the Ordinary Course of Business and subject to the other
     provisions of this Agreement); (D) not to sell, mortgage, pledge, encumber
     or otherwise dispose of any of the Acquired Assets, except General
     Inventory in the Ordinary Course of Business; (E) to maintain all insurance
     coverage currently maintained by the Target in accordance with its present
     business practices; (F) to use reasonable efforts to maintain the goodwill
     associated with the Division; and (G) keep its business and properties
     substantially intact, including its present operations, physical
     facilities, working conditions, and relationships with lessors, licensors,
     suppliers, customers, and employees.

          (ii)   The Target shall promptly notify Buyer of any (A) notice from
     any governmental or regulatory agency or authority in connection with the
     transactions contemplated by this Agreement (except for Tax notices which
     the Target must only advise Buyer of if the same would result in a lien on
     the Assets); or (B) damage to or claim against the Acquired Assets.  

          (iii)  The Target shall use best efforts to duly observe and perform
     in all material respects all terms, conditions and requirements under the
     Contracts.  The Target shall not do any act or omit to do any act, or
     permit any act or omission which would, upon such act or omission or with
     the passage of time, cause a breach or default under any of the Contracts
     or adversely affect Buyer's anticipated operation or ownership of the

                                       18

<PAGE>

     Acquired Assets.

          (iv)   Up to and including August 12, 1998, the Target shall have the
     right and obligation to amend the Disclosure Schedule to include any fact
     or circumstance which would make any representation or warranty set forth
     herein untrue or inaccurate as of such day or as of the date of this
     Agreement.  After August 12, 1998, the Target shall not be entitled to make
     any further amendments and the Disclosure Schedule shall be deemed to be
     final and binding, provided the Target may amend or modify the Disclosure
     Schedule for the sole purpose of disclosing events occurring after such day
     and prior to Closing.  After such day, the Target agrees to promptly notify
     the Buyer of any fact or circumstance of which the Target has Knowledge
     which would make any representation or warranty set forth herein untrue or
     inaccurate as of such day and as of the Closing Date.  No disclosure by the
     Target after such day shall be deemed to amend or supplement the Disclosure
     Schedule or to prevent or cure any misrepresentation, breach of warranty,
     or breach of covenant.

     (d)  FULL ACCESS AND DUE DILIGENCE.  Buyer shall be allowed to conduct such
investigations of the Division and Acquired Assets as Buyer in its sole
discretion deems necessary or desirable, including but not limited to
operational results, condition of the Acquired Assets, legal, marketing and Tax
matters, the Contracts, and the Target's relationship with customers and vendors
generally.  The Target will permit representatives of the Buyer to have full
access at all reasonable times, and in a manner so as not to interfere with the
normal business operations of the Target or the Division to all premises,
properties, personnel, books, records (including Tax records), contracts, and
documents of or pertaining to the Division.

     (e)  EXCLUSIVITY.  Unless the Target's Board of Directors determines that
there would be a material risk of liability on the part of the members of the
Target's Board of Directors to the Target's shareholders, the Target will not
(and the Target will not cause or permit the Division to) (i) solicit, initiate,
or encourage the submission of any proposal or offer from any Person relating to
the acquisition of any capital stock or other voting securities, or any
substantial portion of the assets, of the Division or the Target (including any
acquisition structured as a merger, consolidation, or share exchange), or (ii)
participate in any discussions or negotiations regarding, furnish any
information with respect to, assist or participate in, or facilitate in any
other manner any effort or attempt by any Person to do or seek any of the
foregoing, provided, however, limitations of this Section 5(e) shall not apply
to any of the foregoing actions to the extent such actions have no adverse
effect on the consummation of the transactions contemplated by this Agreement or
on the business of the Division as conducted and presently proposed to be
conducted.  The Target will notify the Buyer immediately if any Person makes any
proposal, offer, inquiry, or contact with respect to any of the foregoing.

     (f)  MARKETING AGREEMENT.  The Parties agree upon execution of this
Agreement to enter into that certain Marketing Agreement in the form attached
hereto as Exhibit 5(f).  Such agreement will govern the Parties mutual efforts
to market and sell products produced by the Division and will expire upon the
Closing Date or upon the earlier termination of this 

                                       19

<PAGE>

Agreement.  

     (g)  NESTLE PRODUCT ORDERS.  The Target shall use best efforts to have
manufactured and delivered to Nestle Clinical Nutrition, Inc. prior to Closing
all enteral feeding pumps currently on order by Nestle. 

     6.   POST-CLOSING COVENANTS.  The Parties agree as follows with respect to
the period following the Closing.

     (a)  GENERAL.  In case at any time after the Closing any further action is
necessary to carry out the purposes of this Agreement, each of the Parties will
take such further action (including the execution and delivery of such further
instruments and documents) as the other Party reasonably may request, at the
sole cost and expense of the requesting Party (unless the requesting Party is
entitled to indemnification therefor under Section 8 below). The Target
acknowledges and agrees that from and after the Closing the Buyer will be
entitled to copies (but not original versions) of all documents, books, records
(including Tax records), agreements, and financial data of any sort relating to
the Division.

     (b)  LITIGATION SUPPORT.  In the event and for so long as any Party
actively is contesting or defending against any action, suit, proceeding,
hearing, investigation, charge, complaint, claim, or demand in connection with
(i) any transaction contemplated under this Agreement or (ii) any fact,
situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act, or transaction on or prior
to the Closing Date involving the Division, the other Party will use reasonable
best efforts to cooperate with the contesting or defending Party and its counsel
in the contest or defense, make available its personnel, and provide such
testimony and access to its books and records as shall be necessary in
connection with the contest or defense, all at the sole cost and expense of the
contesting or defending Party (unless the contesting or defending Party is
entitled to indemnification therefor under Section 8 below).

     (c)  TRANSITION.  The Target will not take any action that is designed or
intended to have the effect of discouraging any lessor, licensor, customer,
supplier, or other business associated with the Division from maintaining the
same business relationships with the Buyer after the Closing as it maintained
with Target and the Division prior to the Closing. The Target will refer all
customer inquiries relating to the business of the Division to the Buyer from
and after the Closing.

     (d)  CONFIDENTIALITY.  The Target will treat and hold as such all of the
Confidential Information, refrain from using any of the Confidential Information
except in connection with this Agreement, and deliver promptly to the Buyer or
destroy, at the request and option of the Buyer, all tangible embodiments (and
all copies) of the Confidential Information which are in its possession.  In the
event that the Target is requested or required (by oral question or request for
information or documents in any legal proceeding, interrogatory, subpoena, civil
investigative demand, or similar process) to disclose any Confidential
Information, the Target will notify the Buyer promptly of the request or
requirement so that the Buyer may seek an appropriate 

                                       20

<PAGE>

protective order or waive compliance with the provisions of this Section 
6(d). If, in the absence of a protective order or the receipt of a waiver 
hereunder, the Target is, on the advice of counsel, compelled to disclose any 
Confidential Information to any tribunal or else stand liable for contempt, 
the Target may disclose the Confidential Information to the tribunal; 
provided, however, that the Target shall use its best efforts to obtain, at 
the request and expense of the Buyer, an order or other assurance that 
confidential treatment will be accorded to such portion of the Confidential 
Information required to be disclosed as the Buyer shall designate.

     (e)  COVENANT NOT TO COMPETE.  For a period of five (5) years from and
after the Closing Date, the Target will not engage directly or indirectly in any
business that the Division conducts as of the Closing Date; provided, however,
that ownership of less than 1% of the outstanding stock of any publicly traded
corporation shall not be deemed solely by reason thereof to be the engagement in
such corporation's businesses.  If the final judgment of a court of competent
jurisdiction declares that any term or provision of this Section 6(e) is invalid
or unenforceable, the Parties agree that the court making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration, or area of the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision, and this Agreement
shall be enforceable as so modified after the expiration of the time within
which the judgment may be appealed.

     (f)  TRANSFER OF POSSESSION OF THE ASSETS.  Except for those Acquired
Assets held by a third party as identified on Schedule 3(f), all tangible forms
of the Acquired Assets shall be available for possession by the Buyer
immediately upon Closing at the Target's location at 9850 51st Ave N.,
Minneapolis, MN.  Such Acquired Assets shall be packaged by the Target in a form
reasonably necessary for safe and insurable shipment by common carrier.  Buyer
shall remove at its expense such Acquired Assets within thirty (30) days of the
Closing Date.  Transfer of the Acquired Assets held by third parties shall be
determined by the Buyer and such third parties.

     (g)  PRODUCT LIABILITY INSURANCE.  For a period of not less than three (3)
years following Closing, the target shall maintain product liability insurance
against product liability claims in policy amounts and with deductibles
identical to that maintained in the ninety (90) day period prior to the date of
this Agreement in such a manner as to provide coverage after Closing (i.e.
"tail" coverage) for any and all claims arising out of products sold by the
Division prior to the Closing Date; provided that such insurance shall not be
less than $1,000,000 per occurrence and $3,000,000 annual aggregate. 

     (h)  PRODUCT LIABILITY CLAIMS.  The Parties acknowledge that, upon
execution of this Agreement, they will simultaneously execute the Marketing
Agreement attached hereto as Exhibit 5(f).  Pursuant to that agreement, Buyer
will immediately begin to act as the exclusive representative of the Target with
respect to the marketing, sales, distribution, and service of the products
relating to the business of the Division as defined in the Marketing Agreement. 
Each Party shall be responsible for its own product liability, if any,
associated with the marketing, 

                                       21

<PAGE>

sales, distribution, and service of the products, whether such activity 
occurs prior to or after the Closing; provided, however, that the Target 
shall indemnify Buyer for all of Buyer's costs and expenses (including legal 
fees) relating to any claims made against Buyer with respect to the purchase 
order between the Target and Nestle Clinical Nutrition, Inc., which order was 
for approximately 750 enteral feeding pumps as of July 24, 1998. Buyer shall 
give written notice of any product liability claim in accordance with Section 
8(d).

     (i)  PRODUCT WARRANTY CLAIMS.  The Target covenants and agrees that it will
be liable for all expenses associated with any warranty claims and product
returns associated with products sold by the Division prior to the Closing Date
to the extent the Target would bear such expenses under the applicable warranty
and return policies offered by the Target for such products.  The Target hereby
authorizes the Buyer, on behalf of the Target, to handle and process all such
claims.  The Target shall reimburse the Buyer for such expenses to the extent
actually incurred by the Buyer and approved in advance by William Rush, Anwar
Bhimani or their successors in office.  The Buyer will provide the Target with a
monthly report and invoice, which shall be payable by the Target within thirty
(30) days, for all claims relating to product returns and ordinary warranty
claims.

and Safety Requirements, or otherwise by operation of law;

                    (2)  any Liability of the Target arising out of the use,

     nature of, or caused by:

                 (A)     any breach or inaccuracy of any of the Buyer's

                                       26

<PAGE>

     (d)  MATTERS INVOLVING THIRD PARTIES.

          (i)    If any third party shall notify any Party (the "Indemnified
     Party") with respect to any matter (a "Third Party Claim") which may give
     rise to a claim for indemnification against the other Party (the
     "Indemnifying Party") under this Section 8, then the Indemnified Party
     shall promptly notify the Indemnifying Party thereof in writing; provided,
     however, that no delay on the part of the Indemnified Party in notifying
     the Indemnifying Party shall relieve the Indemnifying Party from any
     obligation hereunder unless (and then solely to the extent) the
     Indemnifying Party thereby is prejudiced.

          (ii)   The Indemnifying Party will have the right to defend the
     Indemnified Party against the Third Party Claim with counsel of its choice
     reasonably satisfactory to the Indemnified Party so long as (A) the
     Indemnifying Party notifies the Indemnified Party in writing within 15 days
     after the Indemnified Party has given notice of the Third Party Claim that
     the Indemnifying Party will indemnify the Indemnified Party from and
     against the entirety of any Adverse Consequences the Indemnified Party may
     suffer resulting from, arising out of, relating to, in the nature of, or
     caused by the Third Party Claim, (B) the Indemnifying Party provides the
     Indemnified Party with evidence reasonably acceptable to the Indemnified
     Party that the Indemnifying Party will have the financial resources to
     defend against the Third Party Claim and fulfill its indemnification
     obligations hereunder, (C) the Third Party Claim involves only money
     damages and does not seek an injunction or other equitable relief, (D)
     settlement of, or an adverse judgment with respect to, the Third Party
     Claim is not, in the good faith judgment of the Indemnified Party, likely
     to establish a precedential custom or practice materially adverse to the
     continuing business interests of the Indemnified Party, and (E) the
     Indemnifying Party conducts the defense of the Third Party Claim actively
     and diligently.

          (iii)  So long as the Indemnifying Party is conducting the defense of
     the Third Party Claim in accordance with Section 8(d)(ii) above, (A) the
     Indemnified Party may retain separate co-counsel at its sole cost and
     expense and participate in the defense of the Third Party Claim, (B) the
     Indemnified Party will not consent to the entry of any judgment or enter
     into any settlement with respect to the Third Party Claim without the prior
     written consent of the Indemnifying Party (not to be withheld
     unreasonably), and (C) the Indemnifying Party will not consent to the entry
     of any judgment or enter into any settlement with respect to the Third
     Party Claim without the prior written consent of the Indemnified Party (not
     to be withheld unreasonably).

          (iv)   In the event any of the conditions in Section 8(d)(ii) above
     is or becomes unsatisfied, however, (A) the Indemnified Party may defend
     against, and consent to the entry of any judgment or enter into any
     settlement with respect to, the Third Party Claim in any manner it
     reasonably may deem appropriate (and the Indemnified Party need not consult
     with, or obtain any consent from, the Indemnifying Party in connection
     therewith), (B) the Indemnifying Party will reimburse the Indemnified Party
     promptly and periodically for the reasonable costs of defending against the
     Third Party Claim 

                                       27

<PAGE>

     (including reasonable attorneys' fees and expenses), and (C) the
     Indemnifying Party will remain responsible for any Adverse Consequences the
     Indemnified Party may suffer resulting from, arising out of, relating to,
     in the nature of, or caused by the Third Party Claim to the fullest extent
     provided in this Section 8.

     (e)  DETERMINATION OF ADVERSE CONSEQUENCES.  The Parties shall take into
account the time cost of money (using the Applicable Rate as the discount rate)
in determining Adverse Consequences for purposes of this Section 8.  All
indemnification payments under this Section 8 shall be deemed adjustments to the
Purchase Price.

     (f)  CHARGES AGAINST HOLDBACK.  The Buyer shall have the option of
recovering all or any part of any Adverse Consequences it may suffer (in lieu of
seeking any indemnification to which it is entitled under this Section 8) by
notifying the Target that the Buyer is drawing against the amount held in escrow
from the Purchase Price under Section 2(f).

     (g)  INDEMNITY THRESHOLD AND LIMIT.  No Party shall be entitled to
indemnification under this Section 8 unless and until the aggregate amount of
valid claims against the other Party pursuant to the provisions of Section 8(b)
or 8(c) exceed ten thousand dollars ($10,000.00) (the "Indemnity Threshold"). 
If the Indemnity Threshold is exceeded, the Indemnified Party shall be entitled
to the entire amount of such claims from the other Party, including the amount
up to the Indemnity Threshold as well as the amount exceeding the Indemnity
Threshold.  In no event shall either Party be liable to the other for a claim or
claims for indemnification arising under Section 8(b)(i)(A) or  Section
8(c)(i)(A) (including related claims arising under of Section 8(b)(i)(D) or 
Section 8(c)(i)(D)) which in the aggregate exceeds Eight Hundred Thousand
Dollars ($800,000).  

     (h)  EXCLUSIVE REMEDY.  After the Closing, the rights set forth in this
Section 8 shall be each Party's sole and exclusive remedies against the other
Party for misrepresentations or breaches of covenants contained in this
Agreement.  Nothing herein shall prevent any Party from demanding arbitration or
bringing an action in accordance with the terms of this Agreement based upon
allegations of fraud or intentional breach of an obligation of or with respect
to either Party in connection with this Agreement.  

     9.   TERMINATION.

     (a)  TERMINATION OF AGREEMENT.  Certain of the Parties may terminate this
Agreement as provided below:

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

          (ii)   the Buyer may terminate this Agreement by giving written
     notice to the Target on or before August 14, 1998, if the Buyer is not
     reasonably satisfied with the results of its continuing business, legal,
     environmental, and accounting due diligence regarding the Target and the
     Division;

                                       28

<PAGE>

          (iii)  the Buyer may terminate this Agreement by giving written
     notice to the Target at any time prior to the Closing (A) in the event the
     Target has breached any material representation, warranty, or covenant
     contained in this Agreement in any material respect, the Buyer has notified
     the Target of the breach, and the breach has continued without cure for a
     period of 30 days after the notice of breach or (B) if the Closing shall
     not have occurred on or before December 31, 1998, by reason of the failure
     of any condition precedent under Section 7(a) hereof (unless the failure
     results primarily from the Buyer itself breaching any representation,
     warranty, or covenant contained in this Agreement); and

          (iv)   the Target may terminate this Agreement by giving written
     notice to the Buyer at any time prior to the Closing (A) in the event the
     Buyer has breached any material representation, warranty, or covenant
     contained in this Agreement in any material respect, the Target has
     notified the Buyer of the breach, and the breach has continued without cure
     for a period of 30 days after the notice of breach or (B) if the Closing
     shall not have occurred on or before December 31, 1998, by reason of the
     failure of any condition precedent under Section 7(b) hereof (unless the
     failure results primarily from the Target itself breaching any
     representation, warranty, or covenant contained in this Agreement).

     (b)  EFFECT OF TERMINATION.  If any Party terminates this Agreement
pursuant to Section 9(a) above, all rights and obligations of the Parties
hereunder shall terminate without any Liability of any Party to the other Party
(except for any Liability of any Party then in breach).

     10.  MISCELLANEOUS.

     (a)  PRESS RELEASES AND PUBLIC ANNOUNCEMENTS.  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 any 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 (in which case the disclosing Party will use its best
efforts to advise the other Party prior to making the disclosure).

     (b)  RISK OF LOSS.  The risk of loss or damage by fire or other casualty
(including loss or damage due to condemnation) to the Acquired Assets (to the
extent they exist in tangible form) shall be upon the Target until Closing.  In
the event of a material loss or damage (including loss or damage due to
condemnation) that occurs prior to the Closing Date, Buyer shall have the option
of terminating this Agreement.  In the event of a non-material loss or damage
occurs prior to the Closing Date, Buyer shall have the option of: (i) taking
such damaged assets and receiving at Closing all insurance proceeds to which the
Target would be entitled as a result of such loss or damage; or (ii) rejecting
such damaged assets entirely and the Purchase Price shall be reduced to reflect
the non-transference of same.

                                       29

<PAGE>

     (c)  OBLIGATIONS UNDER WARN.  The Target will be responsible to satisfy any
and all obligations arising under the Federal Worker Adjustment and Retraining

Assets hereunder and the Target hereby agrees to indemnify Buyer against and
hold Buyer harmless from any and all Adverse Consequences relating to or
resulting from any failure to comply with such obligations. 

     (d)  NO THIRD-PARTY BENEFICIARIES.  This Agreement shall not confer any

International Services Ltd.) other than the Parties and their respective
successors and permitted assigns.

     (e)  ENTIRE AGREEMENT.  This Agreement (including the documents referred to
herein) constitutes the entire agreement between the Parties and supersedes any

matter hereof.

     (f)  SUCCESSION AND ASSIGNMENT.  This Agreement shall be binding upon and
inure to the benefit of the Parties named herein and their respective successors

any or all of which cases the Buyer nonetheless shall remain responsible for the
performance of all of its obligations hereunder).

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

Any Party may send any notice, request, demand, claim, or other communication
hereunder to the intended recipient at the address set forth above using any
other means (including personal delivery, expedited courier, messenger service,
telecopy, telex, ordinary mail, or electronic mail), but no such notice,

Party may change the address to which notices, requests, demands, claims, and

     (j)  GOVERNING LAW.  This Agreement shall be governed by and construed in
accordance with the domestic laws of the State of Utah without giving effect to
any choice or conflict of law provision or rule.

     (k)  AMENDMENTS AND WAIVERS.  No amendment of any provision of this
Agreement shall be valid unless the same shall be in writing and signed by the
Buyer and the Target.  The Target may consent to any such amendment at any time
prior to the Closing with the prior authorization of its board of directors;
provided, however, that any amendment effected after the Target Stockholders
have approved this Agreement will be subject to the restrictions, if any,
contained in the Minnesota Business Corporation Act.  No waiver by any Party of
any default, misrepresentation, or breach of warranty or covenant hereunder,
whether intentional or not, shall be deemed to extend to any prior or subsequent
default, misrepresentation, or breach of warranty or covenant hereunder or
affect in any way any rights arising by virtue of any prior or subsequent such
occurrence.

     (l)  SEVERABILITY.  Any term or provision of this Agreement that is invalid
or unenforceable in any situation in any jurisdiction shall not affect the

<PAGE>

proof shall arise favoring or disfavoring any Party by virtue of the 
authorship of any of the provisions of this Agreement.  Any reference to any 
federal, state, local, or foreign statute or law shall be deemed also to 
refer to all rules and regulations promulgated thereunder, unless the context 
requires otherwise.  The word "including" shall mean including without 
limitation. Nothing in the Disclosure Schedule shall be deemed adequate to 
disclose an exception to a representation or warranty made herein unless the 
Disclosure Schedule identifies the exception with reasonable particularity 
and describes the relevant facts in reasonable detail.  The Parties intend 
that each representation, warranty, and covenant contained herein shall have 
independent significance.  If any Party has breached any representation, 
warranty, or covenant contained herein in any respect, the fact that there 
exists another representation, warranty, or covenant relating to the same 
subject matter (regardless of the relative levels of specificity) which the 
Party has not breached shall not detract from or mitigate the fact that the 
Party is in breach of the first representation, warranty, or covenant.

     (o)  INCORPORATION OF EXHIBITS AND SCHEDULES.  The Exhibits and Schedules
identified in this Agreement are incorporated herein by reference and made a
part hereof.

     (p)  SPECIFIC PERFORMANCE.  Each of the Parties acknowledges and agrees
that the other Party would be damaged irreparably in the event any of the
provisions of this Agreement are not performed in accordance with their specific
terms or otherwise are breached. Accordingly, each of the Parties agrees that
the other Party shall be entitled to an injunction or injunctions to prevent
breaches of the provisions of this Agreement and to enforce specifically this
Agreement and the terms and provisions hereof in any action instituted in any
court of the United States or any state thereof having jurisdiction over the
Parties and the matter (subject to the provisions set forth in Section 10(q)
below). 

     (q)  DISPUTE RESOLUTION.  

          (i)    The Parties desire to resolve disputes arising out of this
     Agreement without litigation.  Accordingly, except for actions to seek
     temporary restraining orders or injunctions related to the purposes of this
     Agreement, a dispute involving the adjudication of the rights of a third
     party that does not agree to arbitration, or a suit to compel compliance
     with the dispute resolution provision, the Parties agree to use the
     following alternative dispute procedure as their sole remedy with respect
     to any controversy or claim arising out of or relating to this Agreement or
     its breach.

          (ii)   At the written request of a Party, each Party will appoint a
     knowledgeable, responsible representative to meet and negotiate in good
     faith to resolve any dispute arising under this Agreement.  The Parties
     intend that these negotiations be conducted by non lawyer, business
     representatives.  The location, format, frequency, duration and conclusion
     of these discussions shall be left to the discretion of the
     representatives.  Upon agreement between the Parties, the representatives
     may utilize other alternative dispute resolution procedures such as
     mediation to assist in the negotiations.  Discussions and correspondence
     among the representatives for the purposes of these negotiations shall be

                                       32

<PAGE>

     treated as confidential information developed for the purposes of
     settlement, exempt from discovery and production, which shall not be
     admissible in the arbitration described below or in any lawsuit without the
     concurrence of both Parties.  Documents identified in or provided with such
     communications, which are not prepared for purposes of the negotiations,
     are not so exempted and may, if otherwise admissible, be admitted in
     evidence in the arbitration or lawsuit.

          (iii)  If the negotiations do not resolve the dispute within thirty
     (30) days after the initial written request, the disputes shall be
     submitted to binding arbitration by a panel of three arbitrators pursuant
     to the Commercial Arbitration Rules of the American Arbitration
     Association.  A Party may demand such arbitration in accordance with
     procedures set out in those rules.  Each party shall designate, as its
     appointed arbitrator, an impartial individual who is experienced in the
     manufacturer of products similar to the products of the Division.  Within
     20 days of appointment, the two designated arbitrators shall then designate
     by mutual agreement an impartial attorney licensed in the state of the
     arbitration, which attorney shall serve as the panel's administrative head.
     The majority decision of the panel shall final and conclusive upon both
     Parties.  The location of the arbitration shall be in the state and county
     of the Party not instituting the demand for arbitration.  Discovery shall
     be controlled by the arbitrators and shall be permitted to the extent set
     out in this paragraph.  Each Party may submit in writing to a Party, and
     that Party shall respond, to a maximum of any combination of thirty-five
     (35) (none of which may have subplots) of the following:  interrogatories,
     demands to produce documents, and requests for admission.  Each Party is
     also entitled to take the oral deposition of five individuals of the other
     Party.  Additional discovery may be permitted upon mutual agreement of the
     Parties.  The Parties shall contract with the arbitrators to commence the
     arbitration hearing within sixty (60) days of the demand for arbitration. 
     The arbitrators shall control the scheduling so as to process the matter
     expeditiously.  The Parties may submit written briefs.  The Parties shall
     require the arbitrators to rule on the dispute by issuing a written opinion
     within thirty (30) days after the close of the hearings.  The times
     specified in this paragraph may be extended upon a showing of good cause. 
     Judgment upon the award rendered by the arbitrators may be entered in any
     court having jurisdiction.

          (iv)   Each Party shall bear its own cost of these procedures.  A
     Party seeking discovery shall reimburse to the responding Party the costs
     of production of documents (to including search time and reproduction
     costs).  The Parties shall equally split the fees of any mediation, but in
     any arbitration or permissible legal proceedings, the prevailing Party
     shall be entitled to reasonable attorneys' fees, costs and other
     disbursements in addition to any other relief to which such Party may be
     entitled.

     (r)  TAX MATTERS.

          (i)    The Target will be responsible for the preparation and filing
     of all Tax Returns for the Target for all periods as to which Tax Returns
     are due after the Closing 

                                       33

<PAGE>

     Date (including the consolidated, unitary, and combined Tax Returns for the
     Target which include the operations of the Division for any period ending
     on or before the Closing Date).  The Target will make all payments required
     with respect to any such Tax Return.

          (ii)   The Buyer will be responsible for the preparation and filing
     of all Tax Returns for the Division for all periods as to which Tax Returns
     are due after the Closing Date (other than for Taxes with respect to
     periods for which the consolidated, unitary, and combined Tax Returns of
     the Target will include the operations of the Division).  The Buyer will
     make all payments required with respect to any such Tax Return; provided,
     however, that the Target will reimburse the Buyer concurrently therewith to
     the extent any payment of Taxes the Buyer is making relates to the
     operations of the Division for any period ending on or before the Closing
