6.   STOCKHOLDERS' EQUITY

     The Company's 1991 Stock Incentive Plan (Plan) provides for granting to
eligible employees and certain other individuals nonqualified and incentive
options.  The Company had reserved 750,000 shares of common stock for issuance
under the Plan.  In January 1996, the Company's Board of Directors authorized,
and on May 7, 1996, the Company's shareholders approved, an additional 300,000
shares of common stock to be reserved for issuance under the Plan.

     On May 7, 1996, the Company's shareholders also approved the reserve of
250,000 shares of the Company's common stock for issuance pursuant to the 1995
Non-Employee Director Plan (the "1995 Director Plan") established by the Board
of Directors on August 1, 1995.  Options to purchase 42,000 and 10,500 shares of
common stock were granted during 1995 and on May 7, 1996, respectively.  Also on
May 7, 1996, the 52,500 granted options were approved by the Company's
shareholders.

     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION (SFAS 123).  The Company has elected to continue following the
guidance of Accounting Principles Board Opinion No. 25, ACCOUNTING FOR STOCK
ISSUED TO EMPLOYEES, for measurement and recognition of stock-based transactions
with employees.  The Company will adopt the disclosure provisions of SFAS 123 in
1996.

7.   SHAREHOLDER RIGHTS PLAN

     On June 26, 1996 the Company adopted a shareholder rights plan, pursuant to
which the Company declared a dividend distribution of one Preferred Share
Purchase Right on each share of the Company's Common Stock outstanding on August
2, 1996.  Each Right will entitle the holder to buy one-thousandth of a share of
the Company's Series A Junior Preferred Stock, or a combination of securities
and assets of equivalent value, at an exercise price of $80.00, subject to
adjustment.  The description and terms of the Rights are set forth in a Rights
Agreement dated June 26, 1996 between the Company and Norwest Bank Minnesota,
N.A., as Rights Agent.

8.   CONTINGENCY

     On July 17, 1996, the Company reached an agreement with COBE Laboratories
Inc. (COBE) to settle COBE's  patent suit against the Company.  The settlement
was entered into as an expeditious and cost effective means of ending the
protracted litigation and without admission of liability or infringement by
either party.

     The terms of the settlement with COBE provide for the Company to make net
payments totalling $2,200,000, of which a net $1,100,000 was paid in August
1996, for settlement of the suit as well as certain license rights.  The net
settlement costs of $2,200,000 were recognized as a charge to operations, in
addition to the associated legal costs, in the period ended June 30, 1996. The
remaining amount is payable on or about August 6, 1997, subject to COBE's active
enforcement of its claimed patent rights with respect to other manufacturers.
See Part II, Item 1, "Legal Proceedings".

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

     The following is a discussion of the results of operations and financial
condition for the three and six month periods ended June 30, 1996 compared with
the three and six month periods ended June 30, 1995 and should be read in
conjunction with the Company's Consolidated Financial Statements and Notes
thereto.

OVERVIEW

     The Company was incorporated on December 13, 1990.  In June 1991, the
Company acquired the business and assets and assumed certain liabilities of the
surgical division of SCIMED Life Systems, Inc. (the "Predecessor Business").  On
December 1, 1992, the Company exchanged 160,000 shares of its Common Stock for
all of the outstanding shares of AVECOR Cardiovascular Ltd. (formerly Cardio Med
Ltd.) pursuant to which AVECOR Cardiovascular Ltd. became a wholly owned
subsidiary of the Company.  AVECOR Cardiovascular Ltd. had formerly been a
distributor for the Company in the United Kingdom.  In October 1995, the Company
opened a sales office in France which is organized as a subsidiary of AVECOR
Cardiovascular Ltd.

     The assets acquired by the Company from the Predecessor Business included
the Company's line of solid silicone membrane oxygenators.  In October 1991, the
Company introduced its MYOtherm cardioplegia delivery system.  The Company began
marketing its Signature custom tubing packs in July 1993 upon the receipt of
marketing clearance from the U.S. Food and Drug Administration (the "FDA").
Also in July 1993, the Company began international marketing of the Affinity
oxygenator.  In November 1993, the Company received marketing clearance from the
FDA to begin U.S. marketing of the Affinity oxygenator, and the Company released
the device to the U.S. market in February 1994.  In July 1994, the Company
received marketing clearance from the FDA to market its Affinity blood
reservoirs.  In October 1995, the Company received marketing clearance from the
FDA to market its Affinity arterial filter.

RESULTS OF OPERATIONS

NET SALES

THREE MONTHS ENDED JUNE 30, 1996 COMPARED TO THE THREE MONTHS ENDED JUNE 30,
1995

     Net sales increased 38% to $11,145,000 for the three months ended June 30,
1996 from $8,090,000 for the three months ended June 30, 1995.  This increase
was principally the result of a higher volume of product shipments of the
Company's Affinity product line and Signature custom tubing packs.

     Sales from the Affinity product line and Signature custom tubing packs
accounted for approximately 65% and 33% of the overall increase in net sales,
respectively.  The Company began U.S. marketing of the Affinity oxygenator in
late February 1994 and the Affinity blood


                                          9

<PAGE>

reservoirs in July 1994.  U.S. marketing of Signature custom tubing packs began
in July 1993.   Although the Company continues to anticipate declining shipments
of its older solid silicone membrane oxygenator line, net sales of the silicone
line increased by $53,000 for the three months ended June 30, 1996 when compared
to the corresponding period in 1995.

     Sales to customers located outside of the United States were approximately
39% of net sales for the three month period ended June 30, 1996 compared to 42%
of net sales for the corresponding period in 1995.

SIX MONTHS ENDED JUNE 30, 1996 COMPARED TO THE SIX MONTHS ENDED JUNE 30, 1995

     Net sales increased 37% to $21,438,000 for the six months ended June 30,
1996 from $15,687,000 for the six months ended June 30, 1995.  This increase was
principally the result of a higher volume of product shipments of the Company's
Affinity product line and Signature custom tubing packs.

     Sales from the Affinity product line and Signature custom tubing packs
accounted for approximately 64% and 32% of the overall increase in net sales,
respectively.  Although the Company continues to anticipate declining shipments
of the silicone membrane oxygenator line, net sales of the silicone line
increased by $144,000 for the six months ended June 30, 1996 when compared to
the corresponding period in 1995 and by $219,000 when compared to the six months
ended December 31, 1995.  The silicone membrane oxygenator line's net sales
increase for the six months ended June 30, 1996 was primarily due to a large
non-recurring shipment of approximately $290,000 occurring in January 1996.

     Sales to customers located outside of the United States were approximately
39% of net sales for the six month period ended June 30, 1996 compared to 42% of
net sales for the corresponding period in 1995.

COST OF SALES / GROSS PROFIT

     Cost of sales as a percentage of net sales increased to 57.8% for the three
months ended June 30, 1996 from 53.7% for the three months ended June 30, 1995.
Similarly, the cost of sales percentage increased to 57.8% for the six months
ended June 30, 1996 from 54.6% for the six months ended June 30, 1995.  The cost
of sales percentages for the three and six month periods ended June 30, 1996
were unfavorably impacted by significant increases in sales of the Company's
low-margin Signature custom tubing pack line.  The mix of products sold in any
period will influence the cost of sales and gross profit for the period.

     Also, volume-related manufacturing efficiencies have not yet been achieved
for the Company's recently introduced Affinity arterial filter.  Higher
production volumes continued to improve Affinity oxygenator product costs,
although, these improvements were offset, primarily by a decrease in Affinity
oxygenator average selling prices.  Although the gross profit margin may further
benefit from manufacturing efficiencies in the future, given the uncertainty
associated with the ultimate realization of any such efficiencies and the
continuing price pressures characteristic in the Company's markets, the Company
cannot be certain if its gross profit margin will be maintained, decline or
improve.

SELLING, GENERAL AND ADMINISTRATIVE AND LITIGATION EXPENSE

     Selling, general and administrative expenses increased 28% to $2,994,000
for the three months ended June 30, 1996 from $2,344,000 for the three months
ended June 30, 1995.  Selling, general and administrative expenses increased 37%
to $5,851,000 for the six months ended June 30, 1996 from $4,259,000 for the six
months ended June 30, 1995.  This increase is attributed to costs associated
with the continuing development of a direct sales force in certain of the
Company's territories formerly served by distributors and independent sales
representatives, the addition of a Chief Operating Officer and the overall
increase in the Company's sales levels.  In connection with the Company's
development of a direct sales force, in October 1995, the Company opened a sales
office in France from which it fields a direct sales force to serve the French
market.  As a percent of sales, selling, general and administrative expenses
decreased to 26.9% for the three month period ended June 30, 1996 from 27.8% for
the three month period ended March 31, 1996.  This decrease as a percent of
sales is primarily due to the increase in sales for these periods and, as a
result, the fixed portion of selling, general and administrative expenses
becoming a smaller percentage of sales.

     Management anticipates that selling, general and administrative expenses
for the year ended December 31, 1996 will be higher than the year ended December
31, 1995.  Selling, general and administrative expenses for 1996, while expected
to be higher than 1995, should continue to decline as a percentage of sales
dollars.  These forward looking statements will be influenced by revenue
increases achieved by the Company, its ability to attract and retain qualified
sales personnel as the Company continues to develop its direct sales force, and
the timing and extent of promotional activities associated with new product
introductions, if any.

     On July 17, 1996, the Company reached an agreement with COBE Laboratories
Inc. (COBE) to settle COBE's  patent suit against the Company.  The terms of the
settlement with COBE provide for the Company to make net payments totalling
$2,200,000, of which a net $1,100,000 was paid in August 1996.  The remaining
amount is payable on or about August 6, 1997, subject to COBE's active
enforcement of its claimed patent rights with respect to other manufacturers.
The Company expensed settlement costs and professional fees, in connection with
the COBE suit, of approximately $3,700,000 and $4,205,000 for the three and six
month periods ended June 30, 1996, respectively, compared to $60,000 and $80,000
for the corresponding periods in 1995.  See Consolidated Financial Statements -
Note 8 "Contingency" and Part II, Item 1, "Legal Proceedings".

RESEARCH AND DEVELOPMENT

     Research and development expenses increased 34% to $861,000 and 28% to
$1,703,000 for the three and six month periods ended June 30, 1996,
respectively, from $644,000 and $1,329,000 for the three and six month periods
ended June 30, 1995, respectively.  This increased research and development
spending is a result of the Company's ongoing efforts to pursue a number of
potential product opportunities. These opportunities include a new blood pump
for which the Company expects to submit a 510(k) application with the FDA in the
third quarter of 1996, although there can be no assurance that the Company will
file a 510(k) for this device, that the appropriate marketing clearance from the
FDA will be received on a timely basis, if at all, or, if received, that this
device will become commercially successful.


                                          11

<PAGE>


     The Company anticipates that research and development expenses for the
remainder of 1996 will approximate the spending level for the six months ended
June 30, 1996, as the Company moves to expand and improve its proprietary line
of disposable medical devices.  This forward looking projection is dependent on
the extent and timing of new product development and the impact of the
regulatory process in obtaining marketing clearance for new products, including
the new blood pump.  The need or desire to modify the Company's existing
products could also influence the level of research and development expenses.
There can be no assurance, however, that the Company's research and development
efforts will result in any commercially successful products.

INTEREST INCOME

     Interest income increased to $194,000 for the three months ended June 30,
1996 from $68,000 for the three months ended June 30, 1995.  Similarly, interest
income increased to $403,000 for the six months ended June 30, 1996 from
$122,000 for the six months ended June 30, 1995.  Interest income during the
periods ended June 30, 1996 was earned primarily from the investment of the net
proceeds from the Company's June 1995 stock offering.  At June 30, 1996, the
majority of these proceeds were invested with one investment portfolio manager
who invested in U.S. government securities, agency paper, money markets,
commercial paper and corporate obligations.

INCOME TAX PROVISION

     For the three and six month periods ended June 30, 1996, a tax benefit of
$783,000 and $647,000 was recorded, respectively, compared to a tax provision of
$160,000 and $310,000 for the three and six month periods ended June 30, 1995,
respectively.  The tax benefit recorded corresponds to the pretax losses
incurred for those periods.  These losses are primarily due to the litigation
expense incurred during the three and six month periods ended June 30, 1996 in
connection with the Cobe lawsuit.

NET INCOME (LOSS)

     Net loss was $1,877,000 or $.24 per share and $1,664,000 or $.22 per
share for the three and six month periods ended June 30, 1996, respectively,
compared to net income of $608,000 or $.09 per share and $1,273,000 or $.19 per
share for the three and six month periods ended June 30, 1995, respectively.

LIQUIDITY AND CAPITAL RESOURCES

     Capital expenditures totaled $1,057,000 for the six months ended June 30,
1996, compared to $429,000 for the six months ended June 30, 1995.  These
expenditures were primarily related to the addition of equipment, molds and
tooling necessary to further the production of the Affinity oxygenator, related
blood reservoirs and arterial filter.  Additionally, in 1996, preliminary
capital spending began for the equipment, molds and tooling for the production
of a new blood pump.  These capital expenditures also include approximately
$100,000 of preliminary spending for a new facility.  The Company's capital
expenditures for 1996 are expected to be approximately $1,500,000, not including
any capital expenditures which may be required in connection with new
facilities, as discussed below.  The actual amount of this forward looking
projection of capital expenditures will depend on the progress of the Company's
product development efforts and the timing of the receipt of FDA marketing
clearance for any future products, including the new blood pump.

     Leases for the Company's U.S. manufacturing, research and development and
administrative facilities expire on December 31, 1996.  The Company is currently
negotiating a contract for the construction of a different facility into which
all operations will be consolidated.  It is the Company's intent to purchase
this facility.  The estimated cost of this facility is $8,500,000.  The Company
believes it can obtain long-term financing for this entire amount, however, the
Company has not yet determined to what extent it will utilize this financing or
its own cash for this project.  The Company may also need to provide up to
$3,000,000 in interim construction financing.  These expenditures are expected
to be primarily incurred during the fourth quarter of 1996 with ultimate
financing completed in the first quarter of 1997.  These forward looking
statements relating to the amount of capital expenditures and ultimate cash
usage for the new facility is dependent on the final construction
specifications, the nature of the underlying construction contract, timing of
construction and the financing terms the Company is able to negotiate for the
new facility.  The Company anticipates that facilities costs will be
significantly higher in 1997 than 1996, but the extent of the Company's
investment or impact on future cost of operations will not be determinable until
construction and financing arrangements are finalized.

     For the six months ended June 30, 1996, the Company used $3,208,000 in
operating activities compared to $1,272,000 of net cash generated from operating
activities for the same period in 1995.  The net change of approximately
$4,480,000 is primarily the result of reduced net income, including
approximately $2,000,000 in legal expenses, and increasing levels of accounts
receivable and inventory resulting from increasing revenues.   The Company
believes that its existing cash and investments as well as anticipated cash
generated from operations will be sufficient to satisfy the Company's cash
requirements for the foreseeable future.

     In March 1996, net proceeds of approximately $525,000 were generated from
an exercise of the Company's stock warrants.  At June 30, 1996, the majority of
these proceeds, along with the net proceeds from the Company's offering of
common stock in June 1995, remained in cash and cash equivalents and short-term
and long-term investments and will be used for general corporate purposes,
including research and development, working capital and possible acquisitions.

     As discussed above under "Results of Operations - Selling, General and
Administrative and Litigation Expense", on July 17, 1996, the Company reached an
agreement with COBE to settle COBE's patent suit against the Company.  The terms
of the settlement provide for the Company to make net payments totalling
$2,200,000, of which a net $1,100,000 was paid in August 1996.  The remaining
amount is payable on or about August 6, 1997, subject to COBE's active
enforcement of its claimed patent rights with respect to other manufacturers.
See Consolidated Financial Statements - Note 8 "Contingency" and Part II, and
Item 1, "Legal Proceedings".

FOREIGN CURRENCY TRANSACTIONS

     Transactions by the Company's international subsidiaries are negotiated,
invoiced and paid in various foreign currencies, primarily pounds sterling, and
U.S. dollars.  Accordingly, the Company is currently subject to risks associated
with fluctuations in exchange rates between the various currencies.

     Substantially all of the Company's other international transactions are
denominated in U.S. dollars.  Fluctuations in currency exchange rates in other
countries may therefore reduce the demand for the Company's products by
increasing the price of the Company's products in the currency of the countries
in which the products are sold.

NEW ACCOUNTING STANDARD

     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION (SFAS 123).  The Company has elected to continue following the
guidance of Accounting Principles Board Opinion No. 25, ACCOUNTING FOR STOCK
ISSUED TO EMPLOYEES, for measurement and recognition of stock-based transactions
with employees.  The Company will adopt the disclosure provisions of SFAS 123 in
1996.

                            PART II.    OTHER  INFORMATION

ITEM 1.   LEGAL PROCEEDINGS.

          On July 17, 1996, the Company reached an agreement with COBE
          Laboratories Inc. (COBE) to settle COBE's patent suit against the
          Company.  The settlement was entered into as an expeditious and cost
          effective means of ending the protracted litigation and without
          admission of liability or infringement by either party.

          The terms of the settlement include certain cross-licensing
          arrangements between COBE and the Company, pursuant to which COBE has
          granted the Company a paid-up license under COBE patents for the
          manufacture and sale of current and future Company products.  In turn,
          the Company has granted COBE a license under Company patents for the
          manufacture and sale of current COBE products and improvements
          thereto, although the scope of the license granted specifically
          excludes the right to manufacture products having certain design
          characteristics that the Company believes to be significant and which
          are currently utilized in the Company's Affinity oxygenator.

          The settlement agreement with COBE provides for the Company to make
          net payments totalling $2,200,000, of which a net $1,100,000 was paid
          in August 1996.  The remaining amount is payable on or about August 6,
          1997, subject to COBE's active enforcement of its claimed patent
          rights with respect to other manufacturers.

                                      ARTICLE I.

The name of the corporation is AVECOR Cardiovascular Inc. (the "Corporation").


                                     ARTICLE II.

The registered office of the Corporation in Minnesota is 13010 County Road 6,

                                     ARTICLE III.

The Corporation shall be authorized to issue two classes of shares of capital
stock to be designated, respectively, "preferred stock" and "common stock."  The
total number of shares of capital stock which the Corporation shall be

                      ----------------------


     We, Anthony Badolato, Chief Executive Officer, and Gregory J. Melsen, 
Chief Financial Officer and Treasurer, of AVECOR Cardiovascular Inc., a 
corporation organized and existing under the Business Corporations Act of the 
State of Minnesota (the "Corporation"), in accordance with the provisions 
thereof, DO HEREBY CERTIFY:

     That pursuant to the authority vested in the Board of Directors by the 
Articles of Incorporation of the Corporation, the said Board of Directors on 
June 26, 1996, adopted the following resolution creating a series of two 
hundred thousand (200,000) shares of Preferred Stock designated as Series A 
Junior Preferred Stock:

     RESOLVED, that pursuant to the authority vested in the Board of 
Directors of this Corporation in accordance with the provisions of its 
Articles of Incorporation, a series of Preferred Stock of the Corporation be 
and it hereby is created, and that the designation and amount thereof and the 
voting powers, preferences and relative, participation, optional and other 
special rights of the shares of such series, and the qualifications, 
limitation or restrictions thereof are as follows:

     Section 1.  DESIGNATION AND AMOUNT.  The shares of such series shall be 
designated as Series A Junior Preferred Stock, par value $.01 per share (the 
"Series A Junior Preferred Shares"), and the number of shares constituting 
such series shall be two hundred thousand (200,000).

     Section 2.  DIVIDENDS AND DISTRIBUTIONS.  

     (a)  Subject to the prior and superior rights of the holders of any 
shares of any series of Preferred Stock ranking prior and superior to 
Series A Junior Preferred Shares with respect to dividends, the holders 
of Series A Junior Preferred Shares shall be entitled to receive, when, 
as and if declared by the Board of Directors out of funds legally 
available for the purpose, quarterly dividends payable in cash on the 
first day of January, March, July and October in each year (each such 
date being referred to herein as a "Quarterly Dividend Payment Date," 
commencing on the


<PAGE>

first Quarterly Dividend Payment Date after the first issuance of a 
share or fraction of a Series A Junior Preferred Share, in an amount per 
share (rounded to the nearest cent) equal to (subject to the provision 
for adjustment hereinafter set forth), 1,000 times the aggregate per 
share amount of all cash dividends, and 1,000 times the aggregate per 
share amount (payable in kind) of all non-cash dividends or other 
distributions other than a dividend payable in shares of Common Stock or 
a subdivision of the outstanding shares of Common Stock (by 
reclassification or otherwise), declared on the Common Stock, par value 
$.01 per share, of the Corporation (the "Common Stock") since the 
immediately preceding Quarterly Dividend  Payment Date, or, with respect 
to the first Quarterly Dividend Payment Date, since the first issuance 
of any share or fraction of a Series A Junior Preferred Share.  In the 
event the Corporation shall at any time after June 26, 1996 (the "Rights 
Declaration Date") (i) declare any dividend on Common Stock payable in 
shares of Common Stock, (ii) subdivide the outstanding Common Stock, or 
(iii) combine the outstanding Common Stock into a smaller number of 
shares, then in each such case the amount to which holders of Series A 
Junior Preferred Shares were entitled immediately prior to such event 
under clause (b) of the preceding sentence shall be adjusted by 
multiplying such amount by a fraction, the numerator of which is the 
number of shares of Common Stock outstanding immediately after such 
event and the denominator of which is the number of shares of Common 
Stock that were outstanding immediately prior to such event.

     (b)  The Corporation shall declare a dividend or distribution on the 
Series A Junior Preferred Shares as provided in paragraph (a) above 
immediately after it declares a dividend or distribution on the Common Stock 
(other than a dividend payable in shares of Common Stock).

     (c)  Dividends shall begin to accrue and be cumulative on outstanding 
Series A Junior Preferred Shares from the Quarterly Dividend Payment Date 
next preceding the date of issue of such Series A Junior Preferred Shares, 
unless the date of issue of such shares is prior to the record date for the 
first Quarterly Dividend Payment Date, in which case dividends on such shares 
shall begin to accrue from the date of issue of such shares, or unless the 
date of issue is a Quarterly Dividend Payment Date or is a date after the 
record date for the determination of holders of Series A Junior Preferred 
Shares entitled to receive a quarterly dividend and before such Quarterly 
Dividend Payment Date, in either of which events such dividends shall begin 
to accrue and be cumulative from such Quarterly Dividend Payment Date.  
Accrued but unpaid dividends shall not bear interest.  Dividends paid on the 
Series A Junior Preferred Shares in an amount less than the total amount of 
such dividends at the time accrued and payable on such shares shall be 
allocated pro rata on a share-by-share basis among all such shares at the 
time outstanding.  The Board of Directors may fix a record date for the 
determination of holders of Series A Junior Preferred Shares entitled to 
receive payment of a dividend or distribution declared thereon, which record 
date shall be no more than 30 days prior to the date fixed for the payment 
thereof.

     Section 3.  VOTING RIGHTS.  In addition to any other voting rights 
required by law, the holders of Series A Junior Preferred Shares shall have 
the following voting rights:

     (a)  Subject to the provision for adjustment hereinafter set forth, each 
Series A Junior Preferred Share shall entitle the holder thereof to 1,000 
votes on all matters submitted to a vote of the stockholders of the 
Corporation.  In the event the Corporation shall at any time after the Rights 
Declaration Date (i) declare any dividend on Common Stock payable in shares 
of Common Stock, (ii) subdivide the outstanding shares of Common Stock, or 
(iii) combine the outstanding shares of Common Stock into a smaller number of 
shares, then in each such case the number of votes per share to which holders 
of Series A Junior Preferred Shares were entitled immediately


                                       2

<PAGE>

prior to such event shall be adjusted by multiplying such number by a 
fraction the numerator of which is the number of shares of Common Stock 
outstanding immediately after such event and the denominator of which is 
the number of shares of Common Stock that were outstanding immediately 
prior to such event.

     (b)  If, on the date used to determine stockholders of record for any 
meeting of stockholders for the election of directors, a default in dividends 
on the Series A Junior Preferred Shares shall exist, the number of directors 
constituting the Board of Directors of the Corporation shall be increased by 
two, and the holders of the Series A  Junior Preferred Shares shall have the 
right at such meeting, voting together as a single class, to elect two 
directors of the Corporation to fill such newly created directorships.  Each 
director elected by the holders of Series A Junior Preferred Shares (herein 
called a "Series A Preferred Director") shall continue to serve as such 
director for the full term for which he shall have been elected, 
notwithstanding that prior to the end of such term a default in dividends 
shall cease to exist.  Any Series A Preferred Director may be removed by, and 
shall not be removed except by, the vote of the holders of record of the 
outstanding Series A Junior Preferred Shares, voting together as a single 
class, at a meeting of the stockholders, or of the holders of Series A Junior 
Preferred Shares called for such purpose.  Thereafter, so long as a default 
in dividends on the Series A Preferred Shares shall exist (i) any vacancy in 
the office of a Series A Preferred Director may be filled (except as provided 
in the following clause (ii)) by an instrument in writing signed by the 
remaining Series A Preferred Director and filed with the Corporation and (ii) 
in the case of the removal of any Series A Preferred Director, the vacancy 
may be filled by the vote of the holders of the outstanding Series A Junior 
Preferred Shares, voting together as a class, at the same meeting at which 
such removal shall be voted.  Each director appointed as aforesaid by the 
remaining Series A Preferred Director shall be deemed, for all purposes 
hereof, to be a Series A Preferred Director.  Whenever the term of office of 
the Series A Preferred Directors shall end and no default in dividends on the 
Series A Junior Preferred Shares shall exist, the number of directors 
constituting the Board of Directors of the Corporation shall be reduced by 
two.  For the purposes of this Section 3(b), a "default in dividends" on the 
Series A Junior Preferred Shares shall be deemed to have occurred whenever 
there shall be an arrearage in the payment of any dividends to which the 
holders of the Series A Junior Preferred Shares are entitled to receive, 
whether or not any such dividends have been declared by the Board of 
Directors, for six consecutive quarters, and, having so occurred, such 
default shall be deemed to exist thereafter until, but only until, all 
accrued dividends on all shares of Series A Junior Preferred Shares then 
outstanding shall have been paid through the last Quarterly Dividend Payment 
Date.

          At any time when such right to elect directors separately as a 
class shall have so vested, the Corporation may, and upon the written request 
of the holders of record of not less than 20% of the then outstanding total 
number of the Series A Junior Preferred Shares shall, call a special meeting 
of holders of such Series A Junior Preferred Shares for the election of 
directors.  In the case of such a written request, such special meeting shall 
be held within 90 days after the delivery of such request, and, in either 
case, at the place and upon the notice provided by law and in the Bylaws of 
the Corporation; provided that the Corporation shall not be required to call 
such a special meeting if such request is received less than 120 days before 
the date fixed for the next ensuing annual or special meeting of stockholders 
of the Corporation.  After the number of directors of the Corporation shall 
have been increased by two as hereinabove provided, the number as so 
increased may thereafter be further increased or decreased in such manner as 
may be permitted by the Articles of Incorporation or By-laws, provided that 
no such action shall impair the


                                       3
<PAGE>

right of the holders of Series A Junior Preferred Shares to elect and to 
be represented by two directors as herein provided.

     (c)  Except as otherwise provided herein, in the Articles of 
Incorporation of the Corporation or by law, the holders of Series A Junior 
Preferred Shares and the holders of Common Stock (and the holders of shares 
of any other series or class entitled to vote thereon) shall vote together as 
one class on all matters submitted to a vote of stockholders of the 
Corporation.

     Section 4.  CERTAIN RESTRICTIONS.

     (a)  Whenever any dividends or other distributions payable on the Series 
A Junior Preferred shares as provided in Section 2 are in arrears, thereafter 
and until all accrued and unpaid dividends and distributions, whether or not 
declared, on Series A Junior Preferred Shares outstanding shall have been 
paid in full, the Corporation shall not:

          (i)   declare or pay dividends on, make any other distributions on, 
     or redeem or purchase or otherwise acquire for consideration any share 
     ranking junior (either as to dividends or upon liquidation, dissolution 
     or winding up) to the Series A Junior Preferred Shares;

         (ii)  declare or pay dividends on or make any other distributions
     on any shares of stock ranking on a parity (either as to dividends or  
     upon liquidation, dissolution or winding up) with the Series A Junior 
     Preferred Shares, except dividends paid ratably on the Series A Junior 
     Preferred Shares and all such parity stock on which dividends are 
     payable or in arrears in proportion to the total amounts to which the 
     holders of all such shares are then entitled;

         (iii) redeem or purchase or otherwise acquire for consideration shares
     of any stock ranking on a parity (either as to dividends or upon 
     liquidation, dissolution or winding up) with the Series A Junior 
     Preferred Shares, provided that the Corporation may at any time redeem, 
     purchase or otherwise acquire shares of any such parity stock in 
     exchange for shares of any stock of the Corporation ranking junior 
     (either as to dividends or upon dissolution, liquidation or winding up) 
     to the Series A Junior Preferred Shares; or 

         (iv)  purchase or otherwise acquire for consideration any Series A
     Junior Preferred Shares, except in accordance with a purchase offer made 
     in writing or by publication (as determined by the Board of Directors) 
     to all holders of such shares upon such terms as the Board of Directors, 
     after consideration of the respective annual dividend rates and other 
     relative rights and preferences of the respective series and classes, 
     shall determine in good faith will result in fair and equitable 
     treatment among the respective series or classes.

     (b) The Corporation shall not permit any subsidiary of the 
Corporation to purchase or otherwise acquire for consideration any 
shares of stock of the Corporation unless the Corporation could, under 
paragraph (a) of this Section 4, purchase or otherwise acquire such 
shares at such time and in such manner.


                                       4

     Section 5.  REACQUIRED SHARES.  Any Series A Junior Preferred 
Shares purchased or otherwise acquired by the Corporation in any manner 
whatsoever shall be retired and cancelled promptly after the acquisition 
thereof.  All such shares shall upon their cancellation become 
authorized but unissued Preferred Stock and may be reissued as part of a 
new series of Preferred Stock to be created by resolution or resolutions 
of the Board of Directors.

     Section 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.  In the event 
of any voluntary or involuntary liquidation, dissolution or winding up 
of the Corporation, the holders of Series A Junior Preferred Shares 
shall be entitled to receive the greater of (a) $1,000.00 per share, 
plus accrued dividends to the date of distribution, whether or not 
earned or declared, or (b) an amount per share, subject to the provision 
for adjustment hereinafter set forth, equal to 1,000 times the aggregate 
amount to be distributed per share to holders of Common Stock.  In the 
event the Corporation shall at any time after the Rights Declaration 
Date (i) declare any dividend on Common Stock payable in shares of 
Common Stock, (ii) subdivide the outstanding shares of Common Stock, or 
(iii) combine the outstanding shares of Common Stock into a smaller 
number of shares, then in each such case the amount to which holders of 
Series A Junior Preferred Shares were entitled immediately prior to such 
event pursuant to clause (b) of the preceding sentence shall be adjusted 
by multiplying such amount by a fraction, the numerator of which is the 
number of shares of Common Stock outstanding immediately after such 
event and the denominator of which is the number of shares of Common 
Stock that were outstanding immediately prior to such event.

     Section 7.  CONSOLIDATION, MERGER, ETC.  In case the Corporation 
shall enter into any consolidation, merger, combination or other 
transaction in which the shares of Common Stock are exchanged for or 
changed into other stock or securities, cash and/or any other property, 
then in any such case the Series A Junior Preferred Shares shall at the 
same time be similarly exchanged or changed in an amount per share 
(subject to the provision for adjustment hereinafter set forth) equal to 
1,000 times the aggregate amount of stock, securities, cash and/or any 
other property (payable in kind), as the case may be, into which or for 
which each share of Common Stock is changed or exchanged.  In the event 
the Corporation shall at any time after the Rights Declaration Date (i) 
declare any dividend on Common Stock payable in shares of Common Stock, 
(ii) subdivide the outstanding shares of Common Stock, or (iii) combine 
the outstanding shares of Common Stock into a smaller number of shares, 
then in each such case the amount set forth in the preceding sentence 
with respect to the exchange or change of Series A Junior Preferred 
Shares shall be adjusted by multiplying such amount by a fraction, the 
numerator of which is the number of shares of Common Stock outstanding 
immediately after such event and the denominator of which is the number 
of shares of Common Stock that were outstanding immediately prior to 
such event.

     Section 8.  NO REDEMPTION.  The Series A Junior Preferred Shares 
shall not be redeemable.

     Section 9.  RANKING.  The Series A Junior Preferred Stock shall 
rank junior to all other series of the Corporation's Preferred Stock as 
to the payment of dividends and the distribution of assets, unless the 
terms of any such series shall provide otherwise.

     Section 10.  FRACTIONAL SHARES.  Series A Junior Preferred Shares 
may be issued in fractions of a share which shall entitle the holder, in 
proportion to such holder's fractional shares, to exercise voting 
rights, receive dividends, participate in distributions and to have the 
benefit of all other rights of holders of Series A Junior Preferred 
Shares.

                              SETTLEMENT AGREEMENT
                                       
     This Settlement Agreement, entered into and effective as of June 30, 1996
(the "Effective Date") is between Cobe Laboratories, Inc. ("Cobe") and Avecor
Cardiovascular, Inc. ("Avecor").

     WHEREAS, Cobe and Avecor are parties to the lawsuit in the United States
District Court for the District of Colorado, captioned COBE LABORATORIES, INC.
V. AVECOR CARDIOVASCULAR, INC., Case No. 95-WY-2284-CB (the "Lawsuit"); and

     WHEREAS, Cobe and Avecor entered into the Binding Term Sheet having an
effective date of June 30, 1996, which provides that Cobe and Avecor shall each
grant a license to the other (the "Licenses") and shall enter into a settlement
agreement, said  Licenses and settlement agreement to be in accord with the
Binding Term Sheet.

     NOW, THEREFORE, in consideration of the settlement, including without
limitation the releases, dismissal of the lawsuit and payments, and the
Licenses, the receipt and adequacy of which are hereby acknowledged by both
parties, Cobe and Avecor agree as follows:

     1.   ENFORCEMENT OF COBE PATENTS.

     (a)  For the five year period beginning on August 6, 1996, Cobe may
actively prosecute patent enforcement litigation under one or more of Cobe
Patents (at least under the '490 patent) against a Significant Manufacturer
having at least a two and one-half percent (2 1/2%) share of sales in the
United States of integrated microporous membrane oxygenators with hard shell
venous reservoirs disposed above the membrane.  Cobe shall be deemed to be
actively prosecuting enforcement if no more than 180 days lapses between
settlement (or license) or final adjudication of one case with one Significant
Manufacturer and the settlement (or license), or filing and service of a
complaint in a subsequent case with another Significant Manufacturer.  For the
purpose of satisfying enforcement under this paragraph 1(a), such settlement
(or license) shall require reasonable consideration.  Notwithstanding anything
to the contrary, if a complaint is not filed and served during the first 12
months following August 6, 1996, Cobe shall be deemed to have satisfied the
foregoing requirements only if Cobe has settled (or licensed) by August 6, 1997
with at least two un-Affiliated Significant Manufacturers with reasonable
consideration from each.

<PAGE>

     (b)  Cobe may, as an alternative to actively prosecuting enforcement under
paragraph 1(a), bring under license of the '490 Patent at least 50% of the
sales in the United States with respect to the calendar year preceeding each
anniversary date of August 6 of integrated microporous membrane oxygenators
with hard shell venous reservoirs disposed above the membrane by all
manufacturers other than Cobe.  Such license, for the purpose of the payments
under paragraph 2, shall require reasonable consideration for the license.

     (c)  The parties shall meet in June of 1997 through 2001 and cooperate to
determine by August 6 of each such year whether Cobe has actively prosecuted
such enforcement as provided in paragraph 1(a) or brought the specified level
of sales under license pursuant to paragraph 1(b) for the prior calendar year.
If the parties fail to agree by August 6 of any such year, and at the request
of either party, the determination shall be made by arbitration in accordance
with the provisions of paragraph 7.  The arbitrator may use a market consultant
to assist in making the determination.  Market share information furnished by
either party shall be held in confidence and may be used only for the purposes
of making any determination required by this paragraph.

     (d)  Nothing herein shall be deemed to constitute Avecor's inducement to
Cobe to commence any lawsuits, to take any position with respect to such
lawsuits or bring any manufacturer under license.  All decisions concerning
whether or not to commence litigation, the claims to be asserted, and the
existence of sufficient legal and factual justification for such claims, or
licensing shall rest solely with Cobe.

     2.   PAYMENTS.

     (a)  As also set forth in the Licenses, in consideration of the
settlement, including without limitation the releases, dismissal of the lawsuit
and the Licenses, and of Cobe's active prosecution of enforcement or licensing
as set forth in paragraph 1, the parties shall make the following payments:
(i)  within five (5) days of August 6, 1996, Avecor shall pay Cobe $1.4M and
Cobe shall pay Avecor $0.3M; and (ii) provided that Cobe has satisfied the
conditions of paragraph 1(a) or 1(b) as of August 6, 1997, Avecor shall pay
Cobe $1.1M within five days after that date.
     
     (b)  As also set forth in the Licenses, the value of the Cobe License 
shall be deemed to abate if neither of the conditions described in paragraphs 
1(a) and 1(b) are met as of August 6 of any year (unless the '490 Patent has 
expired, other than by voluntary abandonment, lapsing or disclaimer) (the 
"Abatement Event").  If the Abatement Event occurs as of August 6, 1997, 
Avecor shall not be obligated

                                       2

<PAGE>

to make the August 6, 1997, payment, as explained above. If the Abatement 
Event occurs as of August 6, 1998, Cobe shall promptly refund $880,000 of 
such payment; and thereafter, $660,000 if the Abatement Event occurs as of 
August 6, 1999, $440,000 as of August 6, 2000, and $220,000 as of August 6, 
2001.  If any payment is withheld or required to be refunded because of an 
Abatement Event, Cobe shall have no further obligations under this paragraph 
2(b).
     
     3.   STAY; VACATION OF TRIAL DATES AND DISMISSAL OF LAWSUIT.  On July 18,
1996, the parties, by their counsel, filed with the Court in the Lawsuit a
joint motion for a stay pending execution of this Settlement Agreement and the
Licenses, and for the vacation of the trial date presently set in this case and
the vacation of such other dates as may have been fixed by the Court for
proceedings in connection with the Lawsuit.  Promptly after the execution of
this Settlement Agreement and the Licenses, the parties shall also execute and
file with the Court a stipulation providing for the dismissal with prejudice of
the Lawsuit.  Each party shall bear its own attorneys' fees and costs arising
out of the Lawsuit.  Costs, if any, for filings in the Lawsuit pursuant to this
Settlement Agreement shall be borne equally by the parties.
     
     4.   RELEASE AND COVENANT NOT TO SUE.
     
     (a)  NO ADMISSION OF LIABILITY.  This Settlement Agreement and the
Licenses shall not be construed as an admission of liability by either party
with respect to the other party's patents or otherwise and is being entered
into by the parties for the purposes of obviating the need for costly and
lengthy litigation or other dispute resolution proceedings.

     (b)  COBE RELEASE OF CLAIMS.  Cobe, on behalf of itself and its
Affiliates, including but not limited to Gambro AB and the Affiliates of Gambro
AB, does hereby release and fully discharge Avecor, its shareholders,
directors, officers, Affiliates, sublicensees under the Licenses, employees,
agents, advisors, customers, distributors and representatives (collectively,

now have or may have or claimed to have or later claim to have against the
Avecor Releasees, or any of them, individually, jointly, or severally, which:

Release of Claims on behalf of itself and its Affiliates, and Gambro AB and its
Affiliates.

     (c)  AVECOR RELEASE OF CLAIMS.  Avecor, on behalf of itself and its
Affiliates, does hereby release and fully discharge Cobe, its shareholders,
directors, officers, Affiliates, sublicensees under the Licenses, employees,

the "Cobe Releasees"), from and against any and all actions, causes of action,
suits, damages (including attorneys' fees), judgments, claims, counterclaims
and crossclaims whatsoever, known or unknown, in law or in equity, which Avecor
and/or its Affiliates and/or its sublicensees under the Licenses, now have or

          (i)  are claims under Title 35 U.S.C. (Patents), SectionSection 100-
399, arising from or relating to the past or future manufacture, use or sale of
any and all oxygenator products of the type manufactured and sold by Cobe or

          (ii) were asserted in the Lawsuit; or

not to sue Cobe, its shareholders, directors, officers, Affiliates,
sublicensees under the Licenses, employees, agents, advisors, purchasers,
customers, distributors and/or representatives for any matter, thing, claim, or
cause of action which is the subject of the Avecor Release of Claims set forth

advisors, purchasers, customers, distributors and/or representatives for any

the possession or control of the party, its attorneys, witnesses or agents.
Pursuant to paragraph 20 of the Protective Order, the parties, and other
persons bound thereto shall continue to be obligated not to disclose Restricted

be construed to limit the right of any attorneys to practice law and to
represent other clients with respect to any matter related to blood oxygenator
devices and related products, and/or the Cobe or Avecor Patents.

     6.   ARBITRATION.  Any dispute between the parties with respect to this
Settlement Agreement or arising out of this Settlement Agreement and the
Licenses shall be resolved by binding arbitration.  All arbitrations shall be
held in Chicago, Illinois and conducted in accordance with the American
Arbitration Association Commercial Arbitration Rules in effect as of August 6,
1996.  The decisions of the arbitrator shall be final and unappealable by the
parties, and may be entered in and enforced by any court of competent
jurisdiction.  The parties further agree that the arbitration shall be
conducted by a single arbitrator who shall be independent of both parties and
shall be a lawyer at least 50% of whose practice is in the field of patent
litigation and licensing.  Arbitration pursuant to this Settlement Agreement or
the Licenses shall be completed and a decision rendered

                                       5

under contract law (other than revocation of the Licenses).  The Licenses shall
remain in full force and effect notwithstanding any breach or any award of
monetary damages.

     (b)  In the event of a breach of this Settlement Agreement, the
nonbreaching party shall provide written notice to the breaching party,

Agreement shall be construed to constitute any party as the partner, employee,

     NOW, THEREFORE, in consideration of the settlement, including without
limitation the releases, dismissal of the lawsuit and payments, as set forth in
the Settlement Agreement, the receipt and adequacy of which are hereby
acknowledged by both parties, Cobe and Avecor agree as follows:

                             Article I:  LICENSE.
                                       
     1.1  LICENSE.  Subject to timely payment of amounts due to it pursuant to
paragraph 2 of this License, Cobe hereby grants to Avecor a worldwide, non-
exclusive, irrevocable license under Cobe Patents to make, have made, use and
sell Avecor Products.  Cobe Patents shall mean U.S. Patents 4,469,659 for
SAMPLING DEVICE FOR BLOOD OXYGENATOR, 4,818,490 (the '490 Patent) for INTEGRAL
BLOOD OXYGENATOR and 4,451,562 for BLOOD OXYGENATOR, including any divisions,
continuations, continuations-in-part, reissues, reexaminations or extensions
thereof or any foreign patents or applications corresponding to any of the
foregoing.  Avecor Products shall mean (i) the products currently sold by
Avecor or Avecor Cardiovascular, Ltd. as of the Effective Date of this License
and (ii) any products developed by or on behalf of Avecor and sold during the
Term of the Cobe Patents.  Term of the Cobe Patents shall mean the term
continuing until each claim of the Cobe Patents has expired, been disclaimed or
declared invalid by a final judgment of a court or administrative agency of
competent jurisdiction from which no appeal can be or has been taken.  For the
purposes of this License, "Affiliate" shall mean any partnership, person,
corporation or other limited liability company which, directly or indirectly,
owns, is owned by, or is under common ownership with, Avecor, Cobe or Gambro
AB, where "owns" and "ownership" mean owning at least fifty-

<PAGE>

one percent (51%) of the equity having the power to vote on or direct the 
affairs thereof.
     
     1.2  SUBLICENSE.  Cobe hereby grants the right to Avecor to grant
sublicenses, express or implied, (i) to Avecor distributors or Avecor's
Affiliates' distributors to sell Avecor Products, (ii) to end use customers of
Avecor and of permitted sublicensees to use Avecor Products and (iii) to its
Affiliates (but only for a term ending if the sublicensee ceases to be an
Affiliate of Avecor) to make, have made, use and sell Avecor Products.
     
     1.3  EXCLUSION OF KNOW-HOW.  Cobe shall have no obligation to transfer to
Avecor any Cobe know-how or technology and grants no license or other rights to
Avecor in such know-how or technology.
     
     1.4  ASSIGNMENT OF LICENSE.  Any person or entity acquiring substantially
all of the assets related to the oxygenator business of Avecor and its
Affiliates, whether by purchase of stock or assets, by merger or other business
combination, or any other means, may succeed to ownership of this License and
all of Avecor's rights hereunder, by assignment or operation of law or
otherwise.  In the event of any such acquisition, Avecor Products for the
purposes of this License shall mean (i) Avecor Products as defined prior to the
acquisition, (ii) products which Avecor has under development and which have
been embodied in a prototype with laboratory test data generated at least six
months prior to the date upon which the acquisition is consummated and (iii)
improvements to the oxygenator (whether integrated with a reservoir or stand
alone) now referred to as the Affinity and any future improvements or additions
to the Affinity line of oxygenators, provided that such improvements or
additions use a substantially similar direction of flow of blood through the
bundle as does the Affinity, as manufactured on the Effective Date of this
License.  The acquiring party may elect at any time after such acquisition,
during the term of this License, to expand the scope of this License from Cobe
to include any additional products not already licensed, subject to payment of
reasonable compensation to Cobe for the additional scope of license.  If the
parties cannot agree on such reasonable compensation, the amount of such
reasonable compensation shall be determined by arbitration under paragraph 8.8
of this License.
     
     1.5  MAINTENANCE OF COBE PATENTS.  Cobe shall have no obligation to
maintain or preserve Cobe Patents, and may determine in its sole discretion
whether to abandon or otherwise weaken or encumber Cobe Patents, but subject to
the effects of Article III of this License.

                               ARTICLE II:  PAYMENTS.

     2.1  AMOUNT.  In consideration of the settlement, including without
limitation the releases, dismissal of the lawsuit and this License and of
Cobe's active prosecution of enforcement or licensing as set forth in Article
III, Avecor shall make the following payments:  (i)  within five (5) days of
August 6, 1996, Avecor shall pay Cobe $1.4M; and (ii) provided that Cobe has

shall pay Cobe $1.1M within five days after that date.
     
     2.2  ABATEMENT.  The value of the Cobe License shall be deemed to abate if
neither of the conditions described in paragraphs 3.1 and 3.2 are met as of
August 6 of any year (unless the '490 Patent has expired, other than by
voluntary abandonment, lapsing or disclaimer) (the "Abatement Event").  If the
Abatement Event occurs as of August 6, 1997, Avecor shall not be obligated to
make the August 6, 1997, payment, as explained above.  If the Abatement Event
occurs as of August 6, 1998, Cobe shall promptly refund $880,000 of such
payment; and thereafter, $660,000 if the Abatement Event occurs as of August 6,
1999, $440,000 as of August 6, 2000, and $220,000 as of August 6, 2001.  If any
payment is withheld or required to be refunded because of an Abatement Event,
Cobe shall have no further obligations under this paragraph 2.2.
                                       
                          ARTICLE III:  ENFORCEMENT.
                                       
     3.1  ENFORCEMENT.  For the five year period beginning on August 6, 1996,
Cobe may actively prosecute patent enforcement litigation under one or more of
Cobe Patents (at least under the '490 patent) against a Significant
Manufacturer having at least a two and one-half percent (2 1/2%) share of sales
in the United States of integrated microporous membrane oxygenators with hard
shell venous reservoirs disposed above the membrane.  Cobe shall be deemed to
be actively prosecuting enforcement if no more than 180 days lapses between
settlement (or license) or final adjudication of one case with one Significant
Manufacturer and the settlement (or license), or filing and service of a
complaint in a subsequent case with another Significant Manufacturer.  For the
purpose of satisfying enforcement under this paragraph 3.1, such settlement (or
license) shall require reasonable consideration.  Notwithstanding anything to
the contrary, if a complaint is not filed and served during the first 12 months
following August 6, 1996, Cobe shall be deemed to have satisfied the foregoing
requirements only if Cobe has settled (or licensed) by August 6, 1997 with at
least two non-Affiliated Significant Manufacturers with reasonable
consideration from each.

                                       3

<PAGE>

     3.2  LICENSING.  Cobe may, as an alternative to actively prosecuting
enforcement under paragraph 1(a), bring under license of the '490 Patent at
least 50% of the sales in the United States with respect to the calendar year
preceding each anniversary date of August 6 of integrated microporous membrane
oxygenators with hard shell venous reservoirs disposed above the membrane by
all manufacturers other than Cobe.  Such license, for the purpose of the
payments under paragraph 2.1, shall require reasonable consideration for the
license.

     3.3  RESOLUTION OF DISPUTES.  The parties shall meet in June of 1997
through 2001 and cooperate to determine by August 6 of each such year whether
Cobe has actively prosecuted such enforcement as provided in paragraph 3.1 or
brought the specified level of sales under license pursuant to paragraph 3.2
for the prior calendar year.  If the parties fail to agree by August 6 of any
such year, and at the request of either party, the determination shall be made
by arbitration in accordance with the provisions of paragraph 8.8.  The
arbitrator may use a market consultant to assist in making the determination.
Market share information furnished by either party shall be held in confidence
and may be used only for the purposes of making any determination required by
this paragraph.

     3.4  NO INDUCEMENT.  Nothing herein shall be deemed to constitute Avecor's
inducement to Cobe to commence any lawsuits, to take any position with respect
to such lawsuits or bring any manufacturer under license.  All decisions
concerning whether or not to commence litigation, the claims to be asserted,
and the existence of sufficient legal and factual justification for such
claims, or licensing shall rest solely with Cobe.  The sole right to institute
suit for infringement and to recover resulting damages under Cobe Patents shall
rest with Cobe.

                         ARTICLE IV:  CONFIDENTIALITY.
                                       
     4.1  CONFIDENTIALITY.  Avecor and Cobe shall be under a duty of
confidentiality as set forth in paragraph 5 of the Settlement Agreement.

                  ARTICLE V:  WARRANTIES AND INDEMNIFICATION.
                                       
     5.1  WARRANTY EXCEPTIONS.  COBE MAKES NO REPRESENTATIONS OR WARRANTIES,
EXPRESS OR IMPLIED AS TO AVECOR PRODUCTS OR THE COBE PATENTS; OR THE
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR THE DESIGN OF ANY AVECOR
PRODUCTS OR THAT THE SAME ARE FREE OF INFRINGING THE RIGHTS OF ANY THIRD
PARTIES.  COBE SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL OR INDIRECT DAMAGES

local law or regulation, either domestically or internationally.

<PAGE>

the irrevocable grant of the license and sublicense.  The license and

the nonbreaching party shall provide written notice to the breaching party, 
whereupon the breaching party shall have 60 days to cure the breach.  In the

construed to constitute any party as the partner, employee, representative, or

relationship between parties hereunder is that of independent contractors with

such obligations so difficult or costly as to make such performance
commercially unreasonable.  Without limiting the foregoing, the following shall
constitute events or conditions of Force Majeure:  acts of state or prolonged
shortage of energy supplies, epidemics, fire, flood, hurricane, typhoon,
earthquake, lightning and explosion.

     8.3  AMENDMENTS AND WAIVER.  No amendment, waiver or consent with respect

                         AVECOR PATENT LICENSE TO COBE
                                       
     This License, entered into and effective as of June 30, 1996 (the
"Effective Date") is between Cobe Laboratories, Inc. ("Cobe") and Avecor
Cardiovascular, Inc. ("Avecor").

     WHEREAS, Cobe and Avecor are parties to the lawsuit in the United States

     WHEREAS, Cobe and Avecor entered into the Binding Term Sheet having an
effective date of June 30, 1996, which provides that Cobe and Avecor shall each
grant a license to the other and shall enter into a settlement agreement
("Settlement Agreement"), said licenses and Settlement Agreement to be in
accord with the Binding Term Sheet.

     NOW, THEREFORE, in consideration of the settlement, including without
limitation the releases, dismissal of the lawsuit and payments, as set forth in
the Settlement Agreement, the receipt and adequacy of which are hereby
acknowledged by both parties, Cobe and Avecor agree as follows:

                             Article I:  LICENSE.
                                       
     1.1  LICENSE.  Subject to timely payment of amounts due to it pursuant

foreign patents or applications corresponding to any of the foregoing.  
Restricted Cobe Products shall mean the oxygenator (whether integrated with a 
reservoir or stand alone) now referred to as the Optima and any future 
improvements or additions to the Optima line of oxygenators, provided that 
such improvements or additions use a substantially similar direction of flow

Effective Date of this License.  Restricted Cobe Products specifically 
excludes oxygenators (whether integrated with a reservoir or stand alone) 
using a radial outward flow of blood as illustrated by but not limited to 
Avecor's Affinity oxygenator. Term of the Avecor Patents shall mean the term 
continuing until each claim of the Avecor Patents has expired, been 
disclaimed, or

<PAGE>

declared invalid by a final judgment of a court or administrative agency of 
competent jurisdiction from which no appeal can be or has been taken.  For 
the purposes of this License, "Affiliate" shall mean any partnership, person, 
corporation or other limited liability company which, directly or indirectly, 
owns, is owned by, or is under common ownership with, Avecor, Cobe or Gambro 
AB, where "owns" and "ownership" mean owning at least fifty-one percent (51%) 
of the equity having the power to vote on or direct the affairs thereof.

     1.2  SUBLICENSE.  Avecor hereby grants the right to Cobe to grant
sublicenses, express or implied, (i) to Cobe and Gambro AB distributors or
Cobe's or Gambro AB's Affiliates' distributors to sell Restricted Cobe
Products, (ii) to end use customers of Cobe and of permitted sublicensees to
use Restricted Cobe Products and (iii) to its Affiliates (but only for a term
ending if the sublicensee ceases to be an Affiliate of Cobe) to make, have
made, use and sell Restricted Cobe Products.
     
     1.3  EXCLUSION OF KNOW-HOW.  Avecor shall have no obligation to transfer
to Cobe any Avecor know-how or technology and grants no license or other rights
to Cobe in such know-how or technology.
     
     1.4  ASSIGNMENT OF LICENSE.  Any person or entity acquiring substantially
all of the assets related to the oxygenator business of Cobe and its
Affiliates, whether by purchase of stock or assets, by merger or other business
combination, or any other means, may succeed to ownership of this License by
assignment or operation of law or otherwise.
     
     1.5  MAINTENANCE AND LITIGATION.  Avecor shall have no obligation to
maintain or preserve Avecor Patents, and may determine in its sole discretion
whether to abandon or otherwise weaken or encumber Avecor Patents.  The sole
right to institute suit for infringement and to recover resulting damages under
Avecor Patents shall rest with Avecor.

                            ARTICLE II:  PAYMENTS.

     2.1  AMOUNT.  In consideration of the settlement, including without
limitation the releasees, dismissal of the lawsuit and this License, Cobe shall
pay Avecor $300,000 within five (5) days of August 6, 1996.

                        ARTICLE III:  CONFIDENTIALITY.
