                           (i)      Within 60 days following each of the Closing
         Date and the termination of Phase II, Seller shall deliver to Buyer a
         statement (in its final and binding form, the "STATEMENT") setting

         WIP and Raw Materials Inventory Amount as of the close of business on
         the date on which Phase II terminates (the "PHASE II INVENTORY
         AMOUNT"), as applicable. In connection with the preparation of the

         BIOCOR oxygenator, the Bard Adaptor and cardioplegia heat exchanger or
         three spools of Mitsubishi fiber (the "WIP AND RAW MATERIALS
         INVENTORY"). Buyer may, at Buyer's election, engage third party
         auditors to observe the physical count of the WIP and Raw Materials
         Inventory, and the fees and expenses of any such third party auditors
         in connection therewith shall be borne by Buyer. Representatives of
         Buyer shall be permitted to observe such physical count. The Statement
         shall be accompanied by a special purpose report by the Chief Financial
         Officer of Seller to the effect that the Closing Inventory Amount or
         the Phase II Inventory Amount, as applicable, has been determined in
         accordance with the Applicable Accounting Principles and this Section
         1.3. During the period immediately following Buyer's receipt of the
         Statement and until the Closing Inventory Amount or the Phase II
         Inventory Amount, as applicable, is finally determined pursuant to this
         Section 1.3(d), Buyer and its representatives and agents shall be
         permitted to review Seller's books and records and working papers
         related to Seller's preparation of the Statement and determination of
         the Closing Inventory Amount or the Phase II Inventory Amount, as
         applicable. The Statement shall become final and binding upon the
         parties 30 days following Buyer's receipt thereof, unless Buyer gives
         written notice of its disagreement ("NOTICE OF DISAGREEMENT") to Seller
         prior to such date. Any Notice of Disagreement shall specify in
         reasonable detail the nature of any disagreement so asserted. If a
         timely Notice of Disagreement is received by Seller, then the Statement
         (as revised in accordance with clause (x) or (y) below) shall become
         final and binding upon the parties on the earliest of (x) the date the
         parties hereto resolve in writing any differences they have with
         respect to the matters specified in the Notice of Disagreement or (y)
         the date all matters in dispute are finally resolved in writing by the
         Accounting Firm. During the 30 days following delivery of a Notice of
         Disagreement, Buyer and Seller shall seek in good faith to resolve in
         writing any differences which they may have with respect to the matters
         specified in the Notice of Disagreement. During such period, Seller
         shall be permitted to review Buyer's working papers relating to the
         Notice of Disagreement. At the end of such 30-day period, Buyer and
         Seller shall submit to a mutually satisfactory independent "big-five"
         accounting firm (the "ACCOUNTING FIRM") for review and resolution of
         all matters which remain in dispute which were included in

                                       -8-
<PAGE>

         the Notice of Disagreement, and the Accounting Firm shall make a final
         determination of the Closing Inventory Amount or the Phase II Inventory
         Amount, as applicable, in accordance with the Applicable Accounting
         Principles. If Buyer and Seller are unable to mutually agree on an
         Accounting Firm, Buyer and Seller shall select a "big-five" Accounting
         Firm by lot (after excluding one big-five accounting firm selected by
         each of Buyer and Seller). The Statement shall become final and binding
         on the parties on the date the Accounting Firm delivers its final
         resolution in writing to the parties (which final resolution shall be
         delivered not more than 45 days following submission of such disputed
         matters). The fees and expenses of the Accounting Firm shall be shared
         equally by Buyer and Seller.

                           (ii)     If the Preliminary Closing Inventory Amount
         is greater than the final WIP and Raw Materials Inventory as of the
         Closing Date determined pursuant to clause (i) above (the "FINAL
         CLOSING INVENTORY AMOUNT"), Buyer shall, and if the Final Closing
         Inventory Amount is greater than the Preliminary Inventory Amount,
         Seller shall, within three business days after the Statement becomes
         final and binding on the parties, make payment by wire transfer to the
         other party in immediately available funds of the amount of such
         difference (and, if such difference exceeds $100,000, interest on the
         amount of such difference at a rate of 8% per annum (the "APPLICABLE
         RATE"), calculated on the basis of the actual number of days elapsed
         over 365, from the Closing Date to the date of payment). If the
         Preliminary Phase II Inventory Amount is greater than the final WIP and
         Raw Materials Inventory as of the termination of Phase II determined
         pursuant to clause (i) above (the "FINAL PHASE II INVENTORY Amount"),
         Seller shall, and if the Final Phase II Inventory Amount is greater
         than the Preliminary Inventory Amount, Buyer shall, within three
         business days after the Statement becomes final and binding on the
         parties, make payment by wire transfer to the other party in
         immediately available funds of the amount of such difference (and, if
         such difference exceeds $100,000, interest on the amount of such
         difference at the Applicable Rate, calculated on the basis of the
         actual number of days elapsed over 365, from the termination of Phase
         II to the date of payment).

                  4.2      AUTHORIZATION. The execution, delivery and
performance of this Agreement, the other Transaction Documents to which Buyer is
a party and the consummation of the transactions contemplated hereby and thereby
have been duly and

                                       -26-
<PAGE>

validly authorized by all requisite action on the part of Buyer, and no other
proceedings on the part of Buyer are necessary to authorize the execution,
delivery or performance of any Transaction Document to which Buyer is a
party. The issuance of the Warrant and the execution, delivery and
performance of this Agreement and the other Transaction Documents to which
Parent is a party have been duly and validly authorized by all requisite
action on the part of the Parent, and no other proceedings on the part of the
Parent are necessary to authorize the issuance of the Warrant, or the
execution, delivery and performance of this Agreement and the Transaction
Documents to which Parent is a party. Each of the Transaction Documents to
which Buyer is a party constitutes a valid and binding obligation of Buyer,
enforceable in accordance with its respective terms, except as enforceability
may be limited by bankruptcy, insolvency, reorganization or other similar
laws relating to or affecting creditors' rights or by general equitable
principles (regardless of whether such enforceability is considered in a
proceeding in equity or at law). Each of the Warrant and the other
Transaction Documents to which Parent is a party constitutes a valid and
binding obligation of the Parent, enforceable in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency,
reorganization or other similar laws relating to or affecting creditors'
rights or by general equitable principles (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

                  4.3      GOVERNMENTAL AUTHORITIES AND CONSENTS. Neither Buyer
nor the Parent is required to submit any notice, report or other filing with any
governmental authority in connection with the execution or delivery by it of
this Agreement or the other Transaction Documents to which it is a party, the
issuance of the Warrant or the consummation of the transactions contemplated
hereby and thereby. No consent, approval or authorization of any governmental or
regulatory authority is required to be obtained by Buyer or the Parent in
connection with the execution and delivery of this Agreement or the other
Transaction Documents to which it is a party, the issuance of the Warrant or the
consummation of the transactions contemplated hereby and thereby.

                  4.4      BROKERAGE. There are no claims for brokerage
commissions, finders' fees or similar compensation in connection with the
transactions contemplated by this Agreement based on any arrangement or
agreement made by or on behalf of Buyer.

                  4.5      CAPITALIZATION OF THE PARENT.

                  (a)      The number of authorized, issued and outstanding
shares of capital stock of the Parent is set forth on the attached
CAPITALIZATION SCHEDULE. The outstanding shares of capital stock of the Parent
are owned of record and beneficially by the persons set forth on the attached
CAPITALIZATION SCHEDULE in the amounts set forth on the attached CAPITALIZATION
SCHEDULE. Except as set forth on the attached CAPITALIZATION SCHEDULE, there are
no rights, subscriptions, warrants, options, conversion rights or agreements of
any kind outstanding to purchase or otherwise acquire any shares of capital
stock or other equity securities of the

                                       -27-
<PAGE>

Parent. Neither the offer nor the issuance or sale of the Warrant or the
shares of capital stock of the Parent issuable upon exercise of the Warrant
(the "WARRANT SHARES") constitutes an event, under any anti-dilution
provisions of any securities issued or issuable by the Parent or any
agreements with respect to the issuance of securities by the Parent, which
will either increase the number of shares issuable pursuant to such
provisions or decrease the consideration per share to be received by the
Parent pursuant to such provisions. Other than the rights granted to Seller
in connection herewith, no holder of any security of the Parent is entitled
to any preemptive rights to purchase securities from the Parent.

                  (b)      The copies of the Certificate of Incorporation and
Bylaws of the Parent delivered to Seller or its counsel prior to the execution
of this Agreement are true and complete copies of the duly adopted Certificate
of Incorporation and Bylaws of Parent in effect as of the date of this
Agreement. The Warrant Shares have been reserved for issuance, and when issued
upon exercise of the Warrant, will be duly authorized, validly issued and
outstanding, fully paid, nonassessable and free and clear of all pledges, liens,
encumbrances and restrictions. The Warrant, and the certificates representing
the Warrant Shares to be delivered upon the exercise of the Warrant, will be
genuine, and the Parent has no knowledge of any fact which would impair the
validity thereof.

                  (c)      Based in part upon the representations and warranties
of Seller contained herein, no consent, authorization, approval, permit or order
of or filing with any governmental or regulatory authority is required under
current laws and regulations in connection with the offer, issuance, sale or
delivery of the Warrant or the offer of the Warrant Shares other than the
qualification thereof, if required, under applicable state securities laws,
which qualification has been or will be effected as a condition hereto. The
Parent has not, directly or through an agent, offered the Warrant or the Warrant
Shares, or any similar securities for sale to, or solicited any offers to
acquire such securities from, persons other than Seller and other accredited
investors. Under the circumstances contemplated hereby, the offer, issuance,
sale and delivery of the Warrant and the offer of the Warrant Shares will not
under current laws and regulations require compliance with the prospectus
delivery or registration requirements of the Securities Act of 1933, as amended.
All outstanding securities of the Parent have been issued in compliance with an
exemption or exemptions from the registration and prospectus delivery
requirements of the Securities Act of 1933, as amended, and from the
registration and qualification requirements of all applicable state securities
laws.

                  4.6      LITIGATION. There are no actions, suits, proceedings,
orders or investigations pending or, to the best of Buyer's or Parent's
knowledge, threatened against or affecting Buyer or Parent as of the date hereof
at law or in equity, or before or by any federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign, which would adversely affect the performance by Buyer or

         of limitations with respect to the liabilities in question expire;

                           (xvii)   the representations and warranties in
         Section 4.5 (Capitalization) shall terminate on the second anniversary
         of the date hereof;

                           (xviii)  the representations and warranties in

         Section 3.13 (Employees), Section 3.17 (Compliance with Laws) (but only

         terminate on the date which is one year after the termination of Phase

                           (xx)     all other representations and warranties in
         this Agreement shall terminate on the first anniversary of the date
         hereof.

PROVIDED THAT any representation or warranty in respect of which indemnity may
be sought under Section 5.2, and the indemnity with respect thereto, shall
survive the time at which it would otherwise terminate pursuant to this Section
5.1 if notice of the inaccuracy or breach thereof giving rise to such right of
indemnity shall have been given pursuant to Section 5.2(d) to the party against
whom such indemnity may be sought prior to such time. The representations and
warranties in this Agreement shall survive for the periods set forth in this
Section 5.1 and such survival shall in no event be affected by any
investigation, inquiry or examination made for or on behalf of Buyer or Seller,
or the knowledge of any of Buyer's or Seller's officers, directors,
shareholders, employees or agents or the acceptance by Buyer or Seller of any
certificate or opinion hereunder.

                  5.2      GENERAL INDEMNIFICATION.

                  (a)      INDEMNIFICATION FOR BENEFIT OF BUYER. Seller shall
indemnify Buyer and its affiliates, stockholders, officers, directors,
employees, agents, representatives, successors and permitted assigns
(collectively, the "BUYER PARTIES") and save and hold each of them harmless
against and pay on behalf of or reimburse such Buyer Parties as and when
incurred for any loss, liability, demand, claim, action, cause of action, cost,
damage, deficiency, tax, penalty, fine or expense, whether or not arising out of
third party claims (including interest, penalties, reasonable attorneys' fees
and expenses and all amounts paid in investigation, defense or settlement of any
of the foregoing) (collectively, "LOSSES") which any such Buyer Party suffers,
sustains or becomes subject to, as a result of, in connection with, relating or
incidental to or by virtue of: (i) any breach of any representation or warranty
of Seller under this Agreement; (ii) any nonfulfillment or breach of any
covenant or agreement by Seller under this Agreement; or (iii) any liability or
obligation of Seller which is an Excluded Liability. All indemnification
payments under this Section 5.2(a) shall be deemed adjustments to the Purchase
Price set forth in Section 1.3 above.

                  (b)      INDEMNIFICATION FOR BENEFIT OF SELLER. Buyer shall
indemnify Seller and its affiliates, stockholders, officers, directors,
employees, agents, representatives, successors and permitted assigns
(collectively, the "SELLER PARTIES") and hold them harmless against any Losses
which any such Seller Party suffers, sustains or becomes subject to, as the
result of, in connection with, relating or incidental to or by virtue of (i) any
breach of any representation or warranty of Buyer under this Agreement (ii) any
nonfulfillment or breach of any covenant or agreement by Buyer under this
Agreement or (iii) any liability which is an Assumed Liability. All
indemnification payments under this Section 5.2(b) shall be deemed adjustments
to the

                                       -30-
<PAGE>

Purchase Price set forth in Section 1.3 above.

                  (c)      MANNER OF PAYMENT. Any indemnification of the Buyer
Parties or the Seller Parties pursuant to this Section 5.2 shall be effected by
wire transfer of immediately available funds from Seller or Buyer, as the case
may be, to an account designated by Buyer or Seller, as the case may be, within
15 days after the determination thereof.

                  (d)      DEFENSE OF THIRD PARTY CLAIMS. Any party making a
claim for indemnification under this Section 5.2 (an "INDEMNITEE") shall notify
the indemnifying party (an "INDEMNITOR") of the claim in writing within 30 days
after receiving written notice of any action, lawsuit, proceeding, investigation
or other claim against it (if by a third party), describing the claim, the
amount thereof (if known and quantifiable), and the basis thereof; PROVIDED THAT
the failure to so notify an Indemnitor shall not relieve the Indemnitor of its
obligations to Indemnitee otherwise than under this Section 5.2. Any Indemnitor
shall be entitled to participate in the defense of such action, lawsuit,
proceeding, investigation or other claim giving rise to an Indemnitee's claim
for indemnification at such Indemnitor's expense, and at its option (subject to
the limitations set forth below) shall be entitled to assume the defense thereof
by appointing a reputable counsel reasonably acceptable to the Indemnitee to be
the lead counsel in connection with such defense; PROVIDED that:

                           (1)      the Indemnitee shall be entitled to
                  participate in the defense of such claim and to employ counsel
                  of its choice for such purpose; PROVIDED THAT the fees and
                  expenses of such separate counsel shall be borne by the
                  Indemnitee (other than any fees and expenses of such separate
                  counsel that are incurred prior to the date the Indemnitor
                  notifies Indemnitee that it is assuming control of such
                  defense which, notwithstanding the foregoing, shall be borne
                  by the Indemnitor);

                           (2)      the Indemnitor shall not be entitled to
                  assume control of such defense and shall pay the fees and
                  expenses of counsel retained by the Indemnitee if (i) the
                  claim for indemnification relates to or arises in connection
                  with any criminal proceeding, action, indictment, allegation
                  or investigation; (ii) the claim seeks an injunction or
                  equitable relief against the Indemnitee; or (iii) the
                  Indemnitor failed or is failing, given all the facts and
                  circumstances of the claim, to take reasonable steps to
                  prosecute or defend such claim with a view towards achieving a
                  successful outcome; and

                           (3)      if the Indemnitor shall control the defense
                  of any such claim, the Indemnitor shall obtain the prior
                  written consent of the Indemnitee (which shall not be
                  unreasonably withheld) before entering into any settlement of
                  a claim or ceasing to defend such claim if, pursuant to or as
                  a result of such settlement or cessation, injunctive or other
                  equitable relief will be imposed against the

                                       -31-
<PAGE>

                  Indemnitee or if such settlement does not expressly and
                  unconditionally release the Indemnitee from all liabilities
                  and obligations with respect to such claim, without prejudice.

                  (e)      OTHER INDEMNIFICATION PROVISIONS. To the extent
permitted by law, the indemnification provisions of this Section 5.2 shall be
the sole and exclusive remedy of the parties and are in lieu of any other
statutory, equitable, common law or other remedy the parties may have relative
to the matters set forth in this Section 5.2, other than claims for specific
performance pursuant to Section 5.9 and Section 6.10 and other than claims based
in fraud or willful misconduct.

                  (f)      ADDITIONAL NOTICE; COOPERATION. In addition to any
notice which an Indemnitee may give to an Indemnitor pursuant to this Section
5.2, each of the parties agrees that it shall give written notice to the other
party hereto promptly upon the receipt of knowledge of a state of facts which,
if not corrected, would in the judgment of the potential Indemnitee be
reasonably likely to become the subject of a claim for indemnification
hereunder; PROVIDED, that the failure of a potential Indemnitee promptly to
notify a potential Indemnitor of any such matter shall not release a potential
Indemnitor, in whole or in part, from their obligations under this Section 5.2
nor shall such failure be deemed a breach of any provision of this Agreement.

                  (g)      TAX BENEFITS AND INSURANCE. All payments for Losses
for which indemnification hereunder is provided shall be net of any tax benefits
or tax savings actually received by the Indemnitee, including by way of
exclusion from income, creation of a deduction, credit or refund for other
taxable periods (which amounts shall be reasonably certain of receipt and
subject to discounting in the case of future periods), as a result of or related
to indemnifiable Losses. All payments for Losses for which indemnification is
provided hereunder shall be net of any amounts the Indemnitee actually recovers
under any third party insurance policy with respect to any Loss; it being
understood that Indemnitee shall not be in any way obligated to seek payment
from its insurer with respect to any Loss.

                  (h)      SUBROGATION. At Seller's election, Seller shall be
subrogated to any claims or rights of Buyer as against any other persons with
respect to any individual Loss of the Buyer Parties which exceeds $450,000 and
has been paid by Seller under this Section 5.2; PROVIDED THAT Seller shall have
satisfied all obligations under this Section 5.2 with respect to such Losses;
PROVIDED FURTHER THAT Seller vigorously pursues such claim against such other
persons and pays to Buyer all amounts received from such other persons until
such time as Buyer's Losses have been reduced to zero; and PROVIDED FURTHER THAT
Seller shall promptly pay to Buyer upon Buyer's request therefor an amount equal
to 300% of any increase in Buyer's insurance policy premiums in the year
following any payment by any of Buyer's insurers (which payment arises out of
Seller's subrogation claim against such insurer of Buyer pursuant to this
Section). Buyer shall cooperate with Seller, to the extent reasonable under the

                                       -32-
<PAGE>

circumstances, at the sole expense of Seller, in connection with the assertion
by Seller of any such claim against any other persons; PROVIDED THAT Buyer shall
not be required to institute litigation or file any claim in a proceeding.

                  (i)      LIMITATIONS. The Seller shall have no liability to
Buyer under Section 5.2(a)(i) of this Agreement unless the Losses resulting
therefrom exceed $150,000 and then only to the extent such Losses exceed
$150,000. In no event shall the liability of Seller under Section 5.2(a)(i) of
this Agreement exceed the lesser of (i) amount of the Purchase Price actually
received by the Seller in cash and (ii) $5,000,000 (the "CAP AMOUNT"); PROVIDED
HOWEVER, that to the extent the Buyer suffers Losses which, in the aggregate,
exceed the amount in clause (i) at such time, Buyer shall, subject to clause
(ii), be entitled to offset such excess against any portion of the Purchase
Price payable in the future by Buyer to Seller hereunder. Upon a final
determination by a court of competent jurisdiction that no money, or a lesser
amount of money, was owing from Seller, or that Buyer is not entitled to the
amount claimed by Buyer pursuant to Section 5.2(a), then the amount that was not
paid to Seller that was finally determined to be required to be paid to Seller
shall be paid to the Seller (together with interest thereon) as calculated at
the Applicable Rate.

                  5.3      EMPLOYEE AND RELATED MATTERS.

                  (a)      TRANSFERRED EMPLOYEES AND OTHER PERSONS. Prior to the
Closing and prior to the completion of the Transition Period (as defined in the
Transition Services Agreement) but in no event more than four times per calendar
year, upon Buyer's request and upon payment by Buyer to Seller of $50 per
request, Seller shall deliver to Buyer in writing a true and correct Employee
List with respect to all employees of Seller and the Subsidiaries (including,
without limitation, production, sales, marketing and manufacturing and quality
assurance technical support personnel) who are dedicated to the Business
(whether located in or outside the United States) (the "BUSINESS EMPLOYEES") and
a list of such other persons whom Seller, in its sole discretion identifies and
recommends that Buyer hire (the "OTHER SUGGESTED PERSONS"). Buyer shall have the
right to solicit and offer employment to any or all of the Business Employees
and Other Suggested Persons throughout the Transition Period (each of which
offers shall be made contingent upon the Business Employee's or Other Suggested
Person's consent to the release of such employee's information or personnel
records to Buyer other than the portions of such information and records that
includes medical information), and at such time as any of the Business Employees
or Other Suggested Persons are offered employment by Buyer, each of Seller and
the Subsidiaries shall terminate its employment relationship, if any, with such
persons. For each Business Employee and Other Suggested Persons, such offer of
employment shall consist of a level of compensation and benefits which is
competitive with the compensation and benefits provided to employees with
similar qualifications in similar positions in the metropolitan area in which
such person is employed. Buyer shall not directly or indirectly through any
other person solicit or offer employment to any employee of Seller or the
Subsidiaries other than the Business Employees

                                       -33-
<PAGE>

and the Other Suggested Persons; PROVIDED HOWEVER, that Buyer shall be
entitled to make offers to and hire any employees of Seller or the
Subsidiaries who approach Buyer on an unsolicited basis or in response to
advertisements. The Business Employees and any Other Suggested Persons who
are employees of Seller or the Subsidiaries and who are offered employment by
Buyer and accept such offer shall be referred to herein as "TRANSFERRED
EMPLOYEES." During the period after the Closing Date and throughout the
Transition Period, the Seller and the Subsidiaries shall continue to employ
the Business Employees who have not been hired by Buyer, subject to its
employee termination policies and economic conditions. Nothing in this
Agreement shall limit Buyer's ability to terminate the employment of any
Transferred Employee at any time and for any reason, including without cause.

                  (b)      SELLER EMPLOYEE BENEFIT PLANS. Notwithstanding any
other provision of this Agreement, on and after the Closing Date, Seller shall
retain the sponsorship of all employee benefit plans maintained by Seller
("SELLER EMPLOYEE BENEFIT PLANS") and all assets of and liabilities attributable
to such plans including any obligations, liabilities or commitments with respect
to the Transferred Employees arising on or before the Closing Date, including
without limitation, under Part 6 of Title I of ERISA and Section 4980B of the
Code relating to any qualifying event occurring on or before the Closing Date.
Buyer agrees that following the Closing it will evaluate the possibility of
accomplishing a plan-to-plan transfer of the accounts of the Transferred
Employees in the Minntech Corporation Profit Sharing and Retirement Plan (the
"Minntech Plan") from the trustee of the Minntech Plan to the trustee of Buyer's
qualified defined contribution plan, and, to the extent such plan-to-plan
transfer is deemed by Buyer to be feasible and economically prudent, take all
reasonable steps to accommodate such transfer.

                  (c)      BENEFIT ARRANGEMENTS FOR TRANSFERRED EMPLOYEES. As of
the Closing Date, Seller shall fully vest all Transferred Employees in all
benefits accrued through the Closing Date under any Seller Employee Benefit
Plan.

                  (d)      OTHER MATTERS. Seller shall be responsible for all
liabilities, obligations and commitments relating to: (i) compensation of the
Transferred Employees for periods prior to date such persons are no longer
employed by Seller and arising as a result of the transactions contemplated by
this Agreement, including severance compensation and bonus payments; and (ii)
payments attributable to any accrued and unpaid vacation, holidays and sick days
to which the Transferred Employees are entitled with respect to all periods
prior to the date such persons are no longer employed by Seller under any
vacation, holiday, sick pay or similar policy or practice of any Seller in
effect immediately preceding the date such persons are no longer employed by
Seller.

                  (e)      MUTUAL COOPERATION. Seller shall use its reasonable
efforts to obtain the consent of each Transferred Employee to the release to
Buyer of any information contained in personnel records relating to such
Transferred Employee and shall promptly upon receipt of

                                       -34-
<PAGE>

such consent (which shall be in a form reasonably satisfactory to Seller),
provide to Buyer, at Buyer's request, any information or copies of personnel
records (including addresses, dates of hire and dependent information)
relating to such Transferred Employee or relating to the service of such
Transferred Employee with Seller (and predecessors of Seller, as applicable).
Seller and Buyer shall each cooperate with the other and shall provide to the
other such documentation, information and assistance as is reasonably
necessary to effect the provisions of this Section 5.3(e).

                  5.4      PRESS RELEASE AND ANNOUNCEMENTS. Without the prior
approval of the other party, neither Buyer nor Seller shall disclose to the
public or to any third party any information concerning the transactions
contemplated hereby, other than disclosures to its financial, legal or other
advisors and to governmental authorities as required or as may, in the
reasonable opinion of counsel, be required by law, including without limitation
the Securities Exchange Act of 1934, as amended. Buyer and Seller shall
cooperate in the preparation of all press releases (and to the extent
practicable shall issue joint press releases) and in contacting customers and
employees.

                  5.5      EXPENSES. Except as otherwise expressly provided in
Section 5.8 below, each party hereto shall pay all of its own costs and expenses
(including attorneys', accountants' and investment bankers' fees and other
out-of-pocket expenses) in connection with the negotiation and execution of this
Agreement, the performance of its obligations hereunder and the consummation of
the transactions contemplated hereby. Without limiting the foregoing, each party
shall pay its own expenses incurred in connection with its efforts to satisfy
the conditions to the other party's obligation to consummate the transactions
contemplated hereby.

                  5.6      FURTHER TRANSFERS; TRANSITION ASSISTANCE.

                  (a)      Each of Seller and Buyer shall, and Seller shall
cause the Subsidiaries to, execute and deliver such further instruments of
conveyance and transfer and take such additional action as the other may
reasonably request to effect, consummate, confirm or evidence the transfer to
Buyer of the Purchased Assets and the assumption by Buyer of the Assumed
Liabilities. Following the Closing, Seller and Buyer agree to cooperate with
each other and to provide each other with all information and documentation
reasonably necessary to permit the preparation and filing of all federal, state,
local and other tax returns with respect to the Business; PROVIDED THAT each
party shall reimburse the other party for such other party's reasonable
out-of-pocket expenses in connection therewith.

                  (b)      From the date hereof, neither Seller nor the
Subsidiaries shall in any manner take or cause to be taken any action which is
designed or intended to discourage brokers, distributors, customers, suppliers,
referral sources, governmental agencies, insurance companies, lessors,
consultants, advisors and other business associates from maintaining the

                                       -35-
<PAGE>

same business relationships with Buyer or the Business after the date of this
Agreement as were maintained with the Business prior to the date of this
Agreement. Other than as contemplated by the Transition Services Agreement,
Seller agrees that subsequent to the Closing it and the Subsidiaries shall
refer all customer inquiries with respect to the Business to Buyer.

                  5.7      CONFIDENTIALITY. Buyer shall keep confidential all
information and materials regarding the Seller, including all information
regarding suppliers set forth in SECTION 3.19, but excluding information and
materials dedicated to, or included in, the Purchased Assets (except to the
extent (i) disclosure of such information is required by law, (ii) the
information was previously known to Buyer, (iii) the information becomes
publicly known except through the actions or inactions of Buyer or (iv)
disclosure of such information is permitted under the Intellectual Property
License Agreement). Seller shall return to Buyer and keep confidential all
information and materials regarding Buyer reasonably designated by Buyer as
confidential (except to the extent (i) disclosure of such information is
required by law, (ii) the information was previously known to Seller or (iii)
the information becomes publicly known except through the actions or inactions
of Seller). Seller shall maintain as confidential and shall not use or disclose
(except as required by law or as authorized in writing by Buyer or if the
information becomes publicly known other than through the actions or inactions
of Seller) any confidential information or materials dedicated to the Purchased
Assets. In the event any party hereto is required by law to disclose any
confidential information, such party shall promptly notify each other party in
writing, which notification shall include the nature of the legal requirement
and the extent of the required disclosure, and shall cooperate with each other
party to preserve the confidentiality of such information consistent with
applicable law.

                  5.8      SALES AND TRANSFER TAXES. All sales, use, excise,
value-added, goods and services, transfer, recording, documentary, registration,
conveyancing and similar taxes that may be imposed on the sale and transfer of
the Purchased Assets (including any stamp, duty or other tax chargeable in
respect of any instrument transferring property (other than the Proprietary
Rights)), together with any and all penalties, interest and additions to tax
with respect thereto, shall be paid by Seller. Buyer and Seller shall cooperate
in timely making all filings, returns, reports and forms as may be required to
comply with the provisions of applicable law in connection with the payment of
any such taxes described in the immediately preceding sentence. Buyer and Seller
shall cooperate in providing each other with appropriate resale exemption
certification and other similar tax and fee documentation. Buyer and Seller
shall each bear equally any recording or similar fees or expenses payable to
governmental agencies or authorities in connection with the sale and transfer of
the Proprietary Rights.

                  5.9      COVENANT NOT TO COMPETE.

                  (a)      Seller agrees that for a period of five years
following the Closing Date it shall not, and it shall not permit any of its
affiliates to, directly or indirectly, either for itself or through any other
person, partnership, corporation or entity, engage in, participate in, or permit
its name to be used by any enterprise engaging in or participating in the
business of designing, developing, manufacturing, packaging, marketing,
advertising, distributing or selling oxygenators, reservoirs, cardioplegia heat
exchangers or cardioplegia heater coolers in the field of cardiosurgery (the
"RESTRICTED BUSINESS") anywhere in the world, except as contemplated by, and in
accordance with the terms of, this Agreement, the Transition Services Agreement,
the Hemoconcentrator Supply and Distribution Agreement and the Ancillary
Products and Plastic Parts Supply Agreement. For purposes of this Agreement, the
term "PARTICIPATE" includes any direct or indirect interest in any enterprise,
whether as a stockholder, partner, joint venturer, franchisor, franchisee or
otherwise (other than by ownership of less than five percent (5%) of the stock
of a publicly held corporation) or rendering any direct or indirect service or
assistance to any person or entity. Seller agrees that this covenant is
reasonably designed to protect Buyer's substantial investment and is reasonable
with respect to its duration, geographical area and scope.

                  (b)      Except as set forth in this Section 5.9(b), Seller
shall not design, develop, manufacture, package, market or sell any
Cardiosurgery Products during the term of the Hemoconcentrator Supply and
Distribution Agreement dated the date hereof between Seller and Buyer. If Seller
develops a concept for a Cardiosurgery Product, Seller shall give written notice
to Buyer of such development (the "DEVELOPMENT NOTICE"). Buyer shall notify
Seller in writing of its interest in marketing and distributing such
Cardiosurgery Product within 30 business days of receipt of the Development
Notice. If Buyer does not so notify Seller of its interest within the 30
business day period, Seller shall be permitted to design, develop, manufacture,
package, market and sell such Cardiosurgery Product without regard to the
provisions of this Section 5.9(b). If Buyer does notify Seller of its interest
within such 30 business day period, the parties shall enter into bona fide
negotiations on an exclusive basis regarding the marketing and distribution by
Buyer of such Cardiosurgery Product for a period of not less than 90 business
days from receipt by Seller of Buyer's written notice of interest thereof (the
"NEGOTIATION PERIOD"). If Seller and Buyer are unable to agree upon mutually
acceptable terms, including price and other material provisions, within the
Negotiation Period and have not mutually agreed to an extension thereof, Seller
shall have the right to enter into a written arrangement within 180 business
days after the expiration of the Negotiation Period for its marketing and
distribution through a third party anywhere in the world (if such marketing and
distribution by such third party can be conducted on terms no less favorable to
Seller than those proposed by Buyer and rejected by Seller). In addition to the
foregoing, if a third party requests Seller to develop or manufacture a
Cardiosurgery Product using that third party's Marketing Requirements for such
Cardiosurgery Product, Seller shall not be restricted in any way from developing
or manufacturing such Cardiosurgery Product for such third

                                       -37-

party. As used herein, "CARDIOSURGERY PRODUCT" shall mean a product used in
cardiosurgery (other than a hemoconcentrator, oxygenator, reservoir,
cardioplegia heat exchanger or cardioplegia heater cooler) which requires
510(k) approval (whether or not previously received) from the FDA prior to
marketing and sale and includes, without limitation, any change, improvement
or modification of or to a product that affects its function, safety and/or
efficacy and results in a product with specifications that fall outside of
the specifications for such product that exist on the date hereof, and any
labeling change to a product for a new indication of use that requires 510(k)
clearance from the FDA to market. As used herein, "MARKETING REQUIREMENTS"
shall mean, with respect to a Cardiosurgery Product, that set of requirements
that includes the following information: the definition of such Cardiosurgery
Product including the performance criteria and physical attributes; maximum
project cost guidelines; ultimate product cost and desired product
availability dates; and other information related to such Cardiosurgery
Product's required marketing constraints.

                  (c)      Nothing contained in this Agreement shall restrict or
prevent Seller from developing, manufacturing, marketing, selling or
distributing fiber or polyurethane tubing, regardless of the end-use of such
fiber or polyurethane tubing.

                  (d)      Seller agrees that for a period of five years
following the Closing Date it shall not, and it shall not permit any of its
affiliates to, directly or indirectly, either for itself or through any other
person, partnership, corporation or entity, solicit the employment of or hire
any Transferred Employee (or any other person who would have been a Transferred
Employee if such employee had accepted Buyer's offer of employment); provided
that after the date which is 6 months from the date hereof, Seller shall not be
prohibited from hiring any Transferred Employee (or any other person who would
have been a Transferred Employee if such employee had accepted Buyer's offer of
employment) who approaches Seller on an unsolicited basis or in response to
advertisements.

                  (e)      If, at the time of enforcement of any of the
provisions of this Section 5.9, a court determines that the restrictions stated
herein are unreasonable under the circumstances then existing, then the parties
hereto agree that the maximum period, scope or geographical area reasonable
under the circumstances shall be substituted for the stated period, scope or
area. The parties further agree that such court shall be allowed to revise the
restrictions contained herein to cover the maximum period, scope or geographical
area permitted by law.

                  (f)      If Seller or any of its affiliates (the "RESTRICTED
PERSONS") breaches, or threatens to commit a breach of, any of the provisions of
this Section 5.9 (the "RESTRICTIVE COVENANTS"), Buyer shall have the right and
remedy to have the Restrictive Covenants specifically enforced by any court of
competent jurisdiction, it being agreed that any breach or threatened breach of
the Restrictive Covenants would cause irreparable injury to Buyer and that money
damages would not provide an adequate remedy to Buyer.

                  5.10     ACCOUNTS RECEIVABLE; PURCHASE ORDERS. Buyer shall
promptly forward to Seller any and all proceeds from accounts receivable to the
extent that such accounts receivable are not included in the Purchased Assets
that are received by Buyer, and Seller and the Subsidiaries shall promptly
forward to Buyer any and all proceeds from accounts receivable included in the
Purchased Assets that are received by either of them, in each such case no less
frequently than weekly. Buyer and Seller agree to furnish the other party with a
reasonably detailed monthly accounting with respect to any payments made to such
other party under this Section 5.10, which accountings shall be subject to audit
by the receiving party (which audits shall contain normal auditing procedures
and techniques). Seller shall continue to collect all outstanding Accounts
Receivable consistent with past practice; PROVIDED HOWEVER, that Buyer shall be
entitled, at its option, to participate with the Seller in collection efforts
with respect to any Accounts Receivable included in the Purchased Assets. In the
event of any partial payment with respect to accounts receivable, a portion of
which are related to Accounts Receivable included in the Purchased Assets and a
portion of which are related to accounts receivable of Seller or the
Subsidiaries not included in the Purchased Assets, such payment shall be
apportioned between Buyer and Seller pro rata based on the amount of such
accounts receivable which is attributable to the Purchased Assets or accounts
receivable of Seller or the Subsidiaries not included in the Purchased Assets,
as applicable, except to the extent that the person owing such amount
specifically specifies a different apportionment. Seller shall promptly forward
to Buyer any purchase orders with respect to the Products.

                  5.11     SHARED CONTRACT. The parties acknowledge that the
contract listed on the SHARED CONTRACTS SCHEDULE attached hereto shall not
constitute a Purchased Asset and shall not be assigned by Seller to Buyer (such
contract being referred to herein as the "SHARED CONTRACT"). With respect to the
Shared Contract, at Buyer's written request, Seller shall cooperate with Buyer
in any reasonable manner in connection with Buyer's efforts to obtain the
agreement of the other party to such Shared Contract to enter into a separate
agreement with Buyer with respect to the matters covered by such Shared Contract
as they relate to the Products and the Business. Until Seller and Buyer are able
to obtain a separate agreement between Buyer and the other party, Buyer agrees
that, until the scheduled termination of such Shared Contract on March 31, 2000,
it shall, at Seller's request and to the extent permitted by such other party,
perform the obligations of Seller under the Shared Contract to the extent
related to the Products in a manner and upon terms which are consistent with the
requirements of such Shared Contract. Further, if Seller and Buyer are unable to
obtain a separate agreement between Buyer and the other party and Buyer is not
permitted by such other party to make available Products pursuant to the
preceding sentence, Buyer shall have the right to require that Seller and the
Subsidiaries use commercially reasonable efforts to perform any such Shared
Contract, to the extent it relates to the Products, as agent for and for the
account of Buyer.

hereof shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and assigns.

                  6.4      SEVERABILITY. Whenever possible, each provision of

under applicable law, but if any provision of this Agreement or the application
of any such provision to any person or circumstance shall be held to be
prohibited by or invalid, illegal or unenforceable under applicable law in any
respect by a court of competent jurisdiction, such provision shall be

GOVERN ALL QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY, INTERPRETATION AND

BY THIS AGREEMENT, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW
RULES OR PROVISIONS (WHETHER OF THE STATE OF ILLINOIS OR ANY OTHER JURISDICTION)
THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE
STATE OF ILLINOIS.

                  6.9      NO STRICT CONSTRUCTION. Notwithstanding the fact that
this Agreement has been drafted and prepared by one of the parties, Buyer and
Seller confirm that both they and their respective counsel have reviewed,
negotiated and adopted this Agreement as the joint agreement and understanding

                  6.10     SPECIFIC PERFORMANCE. Each of the parties
acknowledges and agrees that the other party would be damaged irreparably in the

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 in addition to any other remedy to
which they may be entitled, at law or in equity.

herein expressed or implied (including Sections 5.2 and 5.3) shall give or be

suffer due to the failure to so comply or to provide notice required by any such
law.
