GENERAL

            Aetrium Incorporated (the "Company") designs, manufactures and
markets a variety of electromechanical equipment used in the handling and
testing of microelectronic components, including semiconductor devices known as
integrated circuits ("ICs") and other forms of electronic components. The
Company's primary focus is on high volume electronic component types and on the
latest package designs. The Company's products are purchased primarily by
semiconductor manufacturers and are used in the "back-end" of semiconductor
manufacturing processes. The Company's products automate critical functions to
improve manufacturing yield, raise quality levels, reduce manufacturing costs
and increase product reliability.

            The Company has three principal product lines. The largest, in terms
of revenue, is its broad line of test handlers, which incorporate thermal
conditioning, contactor and automated handling technologies to provide automated
handling of ICs and other electronic components during production test cycles.
Test handler products are primarily produced by the Company's North St. Paul,
San Diego, and Aetrium FSA divisions. Change kits to adapt the Company's test
handlers to different IC package configurations and to upgrade installed
equipment for enhanced performance also represent a significant part of the
Company's revenue. The Company's second product line consists of its IC
Automation Products, which are produced by the North St. Paul Division. These
products are sold to original equipment manufacturers ("OEMs") to incorporate as
the automated handling components of such OEM's own proprietary equipment for a
variety of other IC processing requirements, such as marking, lead scanning, and
lead trim and form. The Company's third product line is specialty test
equipment, which include reliability test equipment and environmental test
equipment. The Company's reliability test systems provide IC manufacturers with
IC performance data to aid in the evaluation and improvement of IC designs and
manufacturing processes to increase IC yield and reliability and are produced in
North St. Paul, Minnesota. The Company's environmental test equipment products
provide burn-in testing of ICs and are produced in the Company's Lawrence
Division.

            The Company was incorporated in Minnesota in December 1982. The
Company's executive offices are located at 2350 Helen Street, North St. Paul,
Minnesota 55109, and its telephone number is (612) 704-1800.

RECENT DEVELOPMENTS

            Pursuant to an Asset Purchase Agreement dated as of March 20, 1998
(the "Purchase Agreement"), the Company, through its wholly-owned subsidiary,
Aetrium-WEB Technology, L.P., purchased substantially all of the rights, title
and interest in the assets of, and assumed certain liabilities of the equipment
division of WEB Technology, Inc., a Delaware corporation ("WEB"), on April 1,
1998. The total consideration paid by the Company for the assets of WEB was
$7,835,000 ($500,000 of which

<PAGE>


will be paid no later than June 30, 1998, subject to any post-closing adjustment
to the purchase price) and 900,000 shares of Common Stock (the "Acquired
Shares"). Pursuant to the terms of the Purchase Agreement, the Company
distributed the Acquired Shares to the shareholders of WEB in accordance with
their proportionate ownership interests. The Company granted the Selling
Shareholders a one-time demand registration right pursuant to which the shares
offered hereby have been registered. Under the terms of the Purchase Agreement,
the Selling Shareholders are restricted from selling any of the Acquired Shares
during the period that commences on the seventh day of the last month of each of
the Company's fiscal quarters and ends on the third business day after the
Company releases financial results for such quarter. Additionally, certain
Selling Shareholders are further restricted from selling any of the Acquired
Shares held by such Selling Shareholders under a Right of First Refusal
Agreement with the Company pursuant to which such Selling Shareholders agreed to
provide a right of first refusal to the Company on any sale of such Selling
Shareholders' Acquired Shares until March 31, 2000.


                                  RISK FACTORS

            The following risk factors relating to the Company should be
considered in evaluating an investment in the Common Stock.

DEPENDENCE ON SEMICONDUCTOR INDUSTRY

            The Company is in the business of supplying capital equipment to the
manufacturers of integrated circuits and other electronic components within the
semiconductor industry. This industry has been subject to significant market
fluctuations and periodic downturns. Often these developments have had a
disproportionate effect on capital equipment suppliers. The Company has
developed and acquired product lines for the semiconductor market segments which
it feels provide favorable growth opportunities and, accordingly, the Company's
business is most sensitive to market fluctuations in those specific segments.
The Company's future financial performance may be materially adversely affected
by market fluctuations in the semiconductor industry in general, and more
particularly by fluctuations in the industry segments within the Company's
primary focus.

MANAGEMENT OF GROWTH

            Company sales have increased at an average annual compounded growth
rate of approximately 35% during the period from 1986 through 1997. Since
December 1995, the Company has acquired several businesses and product lines: EJ
Systems in December 1995; Forward Systems Automation in April 1997; the Handler
Division of Advantek, Inc. in October 1997; and the equipment division of WEB
Technology, Inc. in April 1998. The Company's strategy is to continue to grow
its revenue base through product acquisition and development. The Company also
expects increases in demand for its products resulting from general growth in
the semiconductor industry. The Company's ability to manage future growth will
be dependent on its success in assimilating these recent and future
acquisitions. The Company's ability to continue to meet increasing production
requirements and manage future growth will also depend in part on its success in
attracting and retaining additional management and technical personnel at each
of its operating locations. Industry growth and low unemployment rates have
increased the competition for such personnel. If the Company is unable to manage
growth effectively and meet increasing production requirements, customer
confidence could erode and demand for the Company's products could deteriorate,
which could materially and adversely affect the Company's business and operating
results.

<PAGE>


FUTURE ACQUISITIONS

            The Company has pursued in the past and continues to pursue
acquisitions of complementary technologies, product lines or businesses. Future
acquisitions by the Company could result in dilutive issuances of equity
securities, and the incurrence of additional debt and amortization expenses
related to goodwill and other intangible assets that could adversely affect the
Company's profitability. In addition, gross profit margins of acquired products,
necessary product or technology development expenditures and other factors that
may be involved in any such acquired business could result in dilution to the
Company's earnings. Acquisitions also may involve numerous other risks,
including difficulties in the assimilation of the operations and products of the
acquired business, dependence on new products and processes, the diversion of
management's attention from other business concerns, risks of entering markets
in which the Company has no or limited direct prior experience, the potential
loss of key employees of the acquired business and difficulties in attracting
additional key employees necessary to absorb added management responsibilities.
No assurance can be given as to the effect of any future acquisition on the
Company's business or operating results.

DEPENDENCE ON NEW PRODUCTS AND PROCESSES

            The market for the Company's products is characterized by rapid
technological change and evolving industry standards and is highly competitive
with respect to timely product innovation. The development of more complex ICs
has driven the need for new equipment and processes to produce such devices at
an acceptable cost. The Company believes that its future success will depend in
part upon its ability to anticipate changes in technology, IC package types and
industry standards and to successfully develop and introduce new and enhanced
products on a timely basis. As a result, the Company expects to continue to make
significant investments in research and development and to continue to consider
from time to time the strategic acquisition of businesses, products and
technologies complementary to the Company's business. If the Company is unable
for technological or other reasons to introduce products in a timely manner in
response to changes in the industry or if products or product enhancements that
the Company develops or acquires do not achieve market acceptance, the Company's
business and operating results could be materially and adversely affected.

POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS

            The Company's operating results may fluctuate based on factors such
as the cancellation and rescheduling of orders, seasonal fluctuations in
business activity, product announcements by the Company or its competitors, and
changes in pricing policies by the Company, its competitors or its suppliers. If
anticipated shipments in any quarter do not occur or are delayed, expenditure
levels could be disproportionately high, and the Company's operating results for
that quarter would be adversely affected. The Company attempts to maintain a
backlog of orders sufficient to reduce the impact of these factors, but there
can be no assurance that backlog levels will be maintained.

COMPETITION

            The markets for the Company's test handlers, IC Automation Products,
and reliability and environmental test systems are highly competitive. Aetrium
competes with a number of companies ranging from very small businesses to large
companies, some of which have substantially greater financial, manufacturing,
marketing and product development resources than the Company. Although the
Company believes its products have competitive advantages over its current
competitors' products, there can be no assurance that the Company will be able
to compete successfully against current and future sources of competition or
that the competitive pressures faced by the Company will not adversely affect
its financial performance.

<PAGE>


CUSTOMER CONCENTRATION

            Many of the Company's end user customers purchase through the
Company's international distributors, and one of the Company's international
distributors represented approximately 12% of the Company's 1997 net sales.
Three of the Company's end customers accounted for approximately 18%, 14% and
10%, respectively, of the Company's 1997 net sales. The Company intends to
continue efforts to broaden its base of customers. However, a reduction, delay
or cancellation of orders from one or more of its significant customers, or the
loss of one or more of such customers could have a material adverse effect on
the Company's business and operating results.

<PAGE>


RELIANCE ON THIRD PARTY DISTRIBUTION CHANNELS

            The Company markets and sells its test handlers and reliability and
environmental test equipment primarily through third party manufacturers'
representatives and international distributors that are not under the direct
control of the Company. The Company has limited internal sales personnel. A
reduction in the sales efforts by the Company's current manufacturers'
representatives or distributors or termination of their relationships with the
Company could adversely affect the Company's business and operating results.

OEM CUSTOMERS FOR IC AUTOMATION PRODUCTS

            The Company markets its IC Automation modules to a number of IC
processing equipment OEMs. The Company's ability to retain its OEM customers and
attract new OEM customers depends on a number of factors, including the changing
needs and financial condition of these customers. Failure of any OEM customer
may not only result in loss of IC Automation product line sales, but also loss
on outstanding receivables due from such OEM.

INTERNATIONAL OPERATIONS

            For the years ended December 31, 1995, 1996 and 1997, approximately
47%, 28% and 30%, respectively, of the Company's net sales were derived from
shipments to international customers, and the Company expects that international
sales will continue to account for a significant portion of its net sales. The
Company's international business may be adversely affected by governmental,
political and economic conditions, including tariff regulations, import quotas
and other factors. While foreign sales are priced in dollars, fluctuations in
currency exchange rates may reduce the demand for the Company's products by
increasing the price of the Company's products in the currency of the countries
to which the products are sold.

DEPENDENCE ON SENIOR MANAGEMENT AND KEY EMPLOYEES

            The Company's success depends on the performance of its executive
officers and other key personnel. The loss of the services of any of its
executive officers or other key employees could have a material adverse effect
on the Company. The Company's future success will also depend in part upon its
ability to attract and retain highly qualified personnel. The Company has not
purchased key-man life insurance on any of its executive officers or other key
employees and currently does not intend to purchase such insurance.

PROTECTION OF INTELLECTUAL PROPERTY

            The Company currently holds several U.S. patents with respect to its
products and technology. There can be no assurance, however, that patents will
be granted in the future or that any patents will be valid or otherwise of value
to the Company. The Company also relies on a combination of copyright,
trademark, trade secret, unfair competition, and other intellectual property
laws, nondisclosure agreements and other protective measures to protect its
rights. Such protection, however, may not preclude competitors from developing
products similar to the Company's products. In addition, the laws of certain
foreign countries do not protect the Company's intellectual property rights to
the same extent as do the laws of the United States. Although the Company
continues to implement protective measures and intends to defend its proprietary
rights vigorously, there can be no assurance that these efforts will be
successful. The Company is not aware of any basis for any infringement claim
against it; however, there

<PAGE>


can be no assurance that third parties will not assert intellectual property
infringement claims against the Company.

DEPENDENCE ON SUPPLIERS

            Certain significant components used in the Company's products,
including certain contactor components, printed circuit boards, refrigeration
systems, and vacuum pumps, are currently available only from sole or limited
sources. Although to date the Company has been able to obtain adequate supplies
of these components and maintains inventories of its more critical components,
the Company's inability in the future to develop alternative sources or to
obtain sufficient sole or limited-source components could result in delays or
reductions in product introductions or shipments, which could have a material
adverse effect on the Company's operating results.

VOLATILITY OF STOCK PRICE

            The Company's Common Stock has experienced in the past, and could
experience in the future, substantial price volatility as a result of a number
of factors, including quarter to quarter variations in the actual or anticipated
financial results of the Company, announcements by the Company, its competitors
or its customers, government regulations, and developments in the semiconductor
industry. In addition, the stock market has experienced extreme price and volume
fluctuations which have affected the market price of many technology companies
in particular and which have at times been unrelated to the operating
performance of the specific companies whose stock is traded. Broad market
fluctuations, as well as economic conditions generally and in the semiconductor
industry specifically, may adversely affect the market price of the Company's
Common Stock.

ANTI-TAKEOVER PROVISIONS: POSSIBLE ISSUANCE OF PREFERRED STOCK; AUTHORITY TO
DIFFERENTIATE COMMON STOCK

            The Company's Restated Articles of Incorporation authorize the
issuance of 2,000,000 shares of undesignated stock (the "Undesignated Stock").
The Company's Board of Directors has the power to issue any or all of the shares
of Undesignated Stock, including the authority to establish the rights and
preferences of the Undesignated Stock, without shareholder approval. In
addition, the Board of Directors has the authority to establish one or more
separate classes or series of Common Stock. Furthermore, as a Minnesota
corporation, the Company is subject to certain "anti-takeover" provisions of the
Minnesota Business Combinations Act. These provisions and the power to issue the
Undesignated Stock and to establish separate classes or series of Common Stock
may, in certain circumstances, deter or discourage takeover attempts and other
changes in control of the Company not approved by management and the Board. As a
result, the Company's shareholders may lose opportunities to dispose of their
shares at the higher prices generally available in takeover attempts or that may
be available under a merger proposal. In addition, these statutory provisions,
the existence of the Undesignated Stock and the Board of Directors' broad
authority with respect to the Common Stock may have the effect of permitting the
Company's current management to retain its position and place it in a better
position to resist changes that shareholders may wish to make if they are
dissatisfied with the conduct of the business.

YEAR 2000 ISSUES

            Many existing computer programs use only two digits to identify a
year in the date field, with the result that data referring to the year 2000 and
subsequent years may be misinterpreted by these programs. If present in the
computer applications of the Company or its suppliers and not corrected, this
problem

<PAGE>


could cause computer applications to fail or to create erroneous results and
could cause a disruption in operations and have an adverse effect on the
Company's business and results of operations. The Company has evaluated its
principal computer systems and has determined that they are substantially Year
2000 compliant. The Company has initiated discussions with its key suppliers to
determine whether they have any Year 2000 issues. The Company has not incurred
any material expenses to date in connection with this evaluation, and does not
anticipate material expenses in the future, depending upon the status of its key
suppliers with respect to this issue.

(1) The Selling Shareholders possess sole voting and investment power with
respect to the shares shown.

(2) This assumes all shares being offered and registered hereunder are sold,
although the Selling Shareholders are not obligated to sell any shares.

(3) Based upon 9,700,153 shares of Common Stock outstanding as of April 1, 1998.


                              PLAN OF DISTRIBUTION

            The Selling Shareholders have advised the Company that sales of the
shares offered hereunder by them, or by their respective pledgees, donees,
transferees or other successors in interest, may be made from time to time in
the over-the-counter market, through negotiated transactions or otherwise, at
market prices prevailing at the time of sale or at negotiated prices. The shares
may be sold by one or more of the following methods: (a) a block trade in which
the broker or dealer so engaged will attempt to sell the shares as agent but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a broker or dealer as principal and resale by such
broker or dealer for its account pursuant to this Prospectus; and (c) ordinary
brokerage transactions and transactions in which the broker solicits purchasers.
Sales may be made pursuant to this Prospectus to or through broker-dealers who
may receive compensation in the form of discounts, concessions or commissions
from the Selling Shareholders or the purchasers of Common Stock for whom such
broker-dealer may act as agent or to whom they may sell as principal, or both
(which compensation as to a particular broker-dealer may be in excess of
customary commissions). To the extent required, one or more supplemental
prospectuses will be filed pursuant to Rule 424 under the Securities Act to
describe any material arrangements for the sales of the shares offered hereunder
when such arrangements are entered into by the Selling Shareholders and any
other broker-dealers that participate in the sale of the shares. In addition,
any shares that qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather than pursuant to this Prospectus. No period of
time has been fixed within which the shares covered by this Prospectus may be
offered or sold.

            The Selling Shareholders and any broker-dealers or other persons
acting on its behalf in connection with the sale of Common Stock hereunder may
be deemed to be an "underwriter" within the meaning of the Securities Act, and
any commissions received by the Selling Shareholders and any profit realized by
them on the resale of Common Stock as principals may be deemed to be
underwriting commissions under the Securities Act. As of the date hereof, there
are no special selling arrangements between any broker-dealer or other person
and any of the Selling Shareholders.

            Pursuant to the terms of the Purchase Agreement, the Company will
pay all the expenses of registering the shares offered hereby, except for
selling expenses incurred by the Selling Shareholders in connection with this
offering, including any fees and commissions payable to broker-dealers or other
persons, which will be borne by the Selling Shareholders. In addition, the
Purchase Agreement provides for certain other usual and customary terms,
including indemnification by the Company of the Selling Shareholders against
certain liabilities arising under the Securities Act.

             *Total................................................ $24,124.59

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

* None of the expenses listed above will be borne by the Selling Shareholders.

ITEM 15.    INDEMNIFICATION OF DIRECTORS AND OFFICERS.

            Minnesota Statutes Section 302A.521 provides that a Minnesota
business corporation must indemnify any director, officer, employee or agent of
the corporation made or threatened to be made a party to a proceeding, by reason
of the former or present official capacity (as defined) of the person, against
judgments, penalties, fines, settlements and reasonable expenses incurred by the
person in connection with the proceeding if certain statutory standards are met.
"Proceeding" means a threatened, pending or completed civil, criminal,
administrative, arbitration or investigative proceeding, including one by or in
the right of the corporation. Section 302A.521 contains detailed terms regarding
such right of indemnification and reference is made thereto for a complete
statement of such indemnification rights. The Company's Restated Articles of
Incorporation also require the Company to provide indemnification to the fullest
extent of the Minnesota indemnification statute.

            The Company maintains directors' and officers' liability insurance,
including a reimbursement policy in favor of the Company.

            Pursuant to Section 8.5(b) of the Purchase Agreement, the directors
and officers of the Company are indemnified by the Selling Shareholders against
certain civil liabilities that they may incur under the Securities Act in
connection with this Registration Statement and the related Prospectus.

ITEM 17.    UNDERTAKINGS.

(a)         The undersigned registrant hereby undertakes:

            (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

                  (i) To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933;

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commissin pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;

            Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
apply if the information required to be included in a post-effective amendment
by those paragraphs is contained in periodic reports filed by registrant
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in the registration statement.

<PAGE>


            (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

(b)         The undersigned registrant hereby undertakes that, for the purposes 
of determining any liability under the Securities Act of 1933, each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

(c)         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions described under Item 15
above, or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

and Buyer will cooperate with Seller, to obtain all non-governmental approvals,
consents or waivers necessary to assign to Buyer all leases, contracts,
licenses, agreements, sales or purchase orders, commitments, property interests,
qualifications or other assets described in Section 1.1 hereof or any claim,
right or benefit arising thereunder or resulting therefrom (the "INTERESTS") as
soon as practicable; provided, however, that neither Seller nor Buyer will be
obligated to pay any consideration therefor (except for filing fees and other
ordinary administrative charges which will be paid by Buyer) to the third party
from whom such approval, consent or waiver is requested.

         To the extent any of the approvals, consents or waivers referred to
above have not been obtained by Seller as of the Closing, Buyer may elect by
written notice to Seller to exclude the applicable Interests and liabilities in
connection therewith from the Assets and the Assumed Liabilities. In the event
Buyer does not make such election, and without limiting the rights of Buyer
under this Agreement, Seller will (a) take all reasonable steps necessary to
obtain the consent of any such third party, (b) cooperate with Buyer in any
reasonable and lawful arrangements designed to provide the benefits of such
Interests to Buyer so long as Buyer fully cooperates with Seller in such
arrangements and promptly reimburses Seller for all payments, charges or other
liabilities made or suffered by Seller in connection therewith (provided that
nothing herein will require Buyer to make any payment or reimbursement of any
consideration for third party consent not agreed to by Buyer), and (c) enforce,
at the request of Buyer and at the expense and for the account of Buyer, any
rights of Seller arising from such Interests against such issuer thereof or the
other party or parties thereto (including the right to elect to terminate any
such Interests in accordance with the terms thereof upon the written advice of
Buyer). To the extent that Seller enters into lawful arrangements designed to

                                        5

<PAGE>


provide the benefits of any Interests as set forth in clause (b) above, such
Interests will be deemed to have been assigned to Buyer for purposes of Section
1.1 hereof.

         1.7 Purchase Price. The aggregate consideration to be paid by Buyer to
Seller for the Assets (the "PURCHASE PRICE") will be Seven Million Eight Hundred
Thirty-Five Thousand Dollars ($7,835,000) (the "CASH CONSIDERATION") and nine
hundred thousand (900,000) shares of the common stock of Aetrium Incorporated
(the "SHARES"), subject to reduction pursuant to the remainder of this Section
1.7:

                  (a) The Cash Consideration will be reduced on a
dollar-for-dollar basis by the amount, if any, by which Seller's Net Current
Assets (as hereinafter defined) on Closing is less than the sum of Three Million
Three Hundred Thirty-Five Thousand Dollars ($3,335,000).

                  (b) Promptly after Closing, Buyer and Seller will cooperate to
prepare a schedule of Seller's Net Current Assets as of Closing in accordance
with United States generally accepted accounting principles ("GAAP") on a basis
consistent with the Latest Balance Sheet (as hereinafter defined), provided that
such schedule will be prepared in accordance with the instructions listed on
Exhibit A hereto regardless of whether such instructions conform to GAAP or are
consistent with the Latest Balance Sheet. In the event the parties cannot agree
on Seller's Net Current Assets as of Closing, any unresolved issues will be
submitted to Ernst & Young, Dallas, Texas office (the "ARBITRATOR ACCOUNTANTS"),
whose decision on any such issues will be final and binding on the parties. "NET
CURRENT ASSETS" means aggregate Accounts Receivable and Inventory less aggregate
trade payables included in Assumed Liabilities. Seller's Net Current Assets as
of Closing as so determined will be binding upon the parties. Buyer and Seller
will use their best efforts to cause Net Current Assets to be determined within
thirty (30) days after Closing. Buyer and Seller will each bear the costs of
their respective accountants and will share equally any fees of the Accountant
Arbitrator incurred in the determination of Seller's Net Current Assets as of
Closing as hereinabove provided.

         1.8 Payment of Purchase Price. The Purchase Price will be payable as
follows:

                  (a) Seven Million Three Hundred Thirty-Five Thousand Dollars
($7,335,000) of the Cash Consideration will be paid at Closing to Seller by wire
transfer of immediately available funds to accounts designated by Seller prior
to Closing.

                  (b) The remainder of the Cash Consideration will be paid to
Seller, together with interest thereon from the Closing Date to the date paid at
the annual rate of six percent (6%) (subject to increase to the late payment
rate provided below if applicable), by wire transfer of immediately available
funds to accounts designated by Seller prior to Closing promptly upon the
earlier of final determination of Seller's Net Current Assets as of Closing or
ninety (90) days after Closing. In the event any adjustment under Section 1.7(a)
reduces the Cash Consideration below the amount then received by Seller
therefor, immediately upon determination of such adjustment Seller will promptly
reimburse Buyer the amount of any such deficit, together with interest thereon
from the Closing Date to the date paid at the annual rate of six percent (6%)
(subject to increase to the late payment rate provided below if applicable), in
immediately available funds to accounts designated by Buyer. In

                                        6


<PAGE>


the event of any delay in any payment due under this Section 1.8(b), such amount
will bear interest from three (3) business days after the due date until paid in
full at the annual rate of twelve percent (12%).

                  (c) The Shares will be issued at Closing under such individual
certificates in such amounts and in the names of such holders (the "SHARE
DESIGNEES") as Seller designates prior to Closing.

         1.9 Allocation of Purchase Price.

                  (a) Buyer will prepare (or cause to be prepared) an allocation
(the "ALLOCATION SCHEDULE") of the Purchase Price (plus Assumed Liabilities and
Buyer's expenses of the transaction) among the Assets. Such allocation will be
made in accordance with Code (as hereinafter defined) Section 1060 and any
applicable rules or regulations thereunder.

                  (b) Seller and Buyer (1) will be bound by the allocation
contained in the Allocation Schedule for purposes of determining any and all
consequences with respect to Taxes of the transactions contemplated herein, (2)
will prepare and file all Tax Returns (as hereinafter defined) in a manner
consistent with such Allocation Schedule (including Form 8594, "Asset
Acquisition Statement"), and (3) will take no position inconsistent with such
Allocation Schedule in any Tax Return, any discussion with or proceeding before
any tax Authority (as hereinafter defined), or otherwise. In the event that such
Allocation Schedule is disputed by any tax Authority, the party receiving notice
of such dispute will promptly notify the other party thereof.

                                        8


<PAGE>


qualification or licensing, except in such jurisdictions in which the failure to

the aggregate, have a material adverse effect on the condition (financial or

reserves, businesses, prospects, customers, customer relations, goodwill or
going concern value ("MATERIAL ADVERSE EFFECT") with respect to Seller. Schedule
3.1 of the Disclosure Schedule contains a list of all jurisdictions in which

         3.2 Authorization. Seller has all requisite corporate power and
authority to execute, deliver and perform this Agreement and to consummate the
transactions contemplated hereby. The execution, delivery and performance by
Seller of this Agreement and the consummation by Seller of the transactions
contemplated hereby have been duly authorized by all necessary corporate action.
This Agreement has been duly and validly executed by Seller and constitutes the
valid and binding legal obligation of Seller, enforceable against Seller in
accordance with its terms, except to the extent that such enforceability (a) may
be limited by bankruptcy, insolvency, reorganization, moratorium or other
similar laws relating to creditors' rights generally, and (b) is subject to
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

         3.3 Non-Contravention. Except as set forth in Schedule 3.3 of the
Disclosure Schedule, neither the execution, delivery and performance of this
Agreement nor the consummation of the transactions contemplated hereby will (a)
violate or be in conflict with any provision of the articles or certificates of
incorporation or bylaws of Seller, or (b) be in conflict with, or constitute a
default, however defined (or an event which, with the giving of due notice or
lapse of time, or both, would constitute such a default), under, or cause or
permit the acceleration of the maturity of, or give rise to any right of
termination, cancellation or imposition of fees or penalties under, any debt,
instrument, agreement, permit or other obligation, commitment or authorization

assets is or may be bound, or (c) result in the creation or imposition of any

Section 1362 to be treated as an "S corporation" for each of its taxable years
ended after February 28, 1989. Seller has not taken any action to revoke such

         3.18 Employee Benefit Plans. Schedule 3.18 of the Disclosure Schedule

related to the employment of any present or former director, officer or employee
of the Division under which Seller has any present or future obligation or
liability (the "EMPLOYEE BENEFIT PLANS"). With respect to each such Employee

scheduled on Schedule 3.18 of the Disclosure Schedule all (a) plans and related
trust documents and amendments thereto, (b) the most recent summary plan
description and the three (3) most recent annual reports on Treasury Form 5500,
including all schedules and attachments thereto, with respect to any Employee
Benefit Plan for which such report is required, (c) the three (3) most recently
issued actuarial valuations, and (d) the most recent determination letter
received from the Internal Revenue Service and the full and complete application

which, and there exists no condition or set of circumstances under which, Seller
or any Employee Benefit Plan that is an "employee pension benefit plan" (as
defined in ERISA Section 3(3)) ("PENSION PLAN") could be subject to any
liability under ERISA Section 502(i) or Code Section 4975. No Pension Plan is

such letter that would adversely affect such qualification or exemption, and (3)

pending with respect to any Employee Benefit Plan or against the assets of any
Employee Benefit Plan. No Pension Plan is a "multiemployer plan," within the
meaning of ERISA Section 3(37), and neither Seller nor any former subsidiary of
Seller has participated in or contributed to a multiemployer plan. With respect
to each Employee Benefit Plan that is a "group health plan" within the meaning
of ERISA Section 601(a) and that is subject to Code Section 4980B, including but
not limited to any medical plan, dental plan, health care reimbursement plan or
employee assistance program, Seller has operated such plans in material
compliance with the continuation coverage requirements of those provisions and
Part 6 of Title I of ERISA and any applicable comparable state Laws, and no
Employee Benefit Plan provides for

medical, health, life or other welfare benefits for present or future terminated
employees or their spouses or dependents in excess of those required to be
provided under such Laws. The transactions contemplated herein will not result
in the acceleration, accrual, vesting, funding or payment of any contribution or
benefit under any Employee Benefit Plan. No action or omission of Seller or any
director, officer, employee, or agent thereof in any way restricts, impairs or
prohibits Seller or any successor thereof from amending, merging, or terminating
any Employee Benefit Plan in accordance with the express terms thereof and
applicable Laws. Neither Seller nor any former subsidiary of Seller has taken
any action which has or could result in any liability to Seller under the Worker
Adjustment and Retraining Notification Act.

create any cause of action by any third party against Seller under any
Environmental Laws.

                  (d) Except as set forth in Schedule 3.22 of the Disclosure

                  Agreement (as hereinafter defined) and otherwise within one
                  (1) business day of receipt of the Sale Notice) notify the

                  If the Holder does not sell the Registrable Securities within
                  thirty (30) days after such notification from Aetrium
                  Incorporated, however, the Holder will once again become

                  may not sell the Registrable Securities without first
                  complying with the procedures described herein.

                           (2) If Aetrium Incorporated determines that the
                  Registration Statement, the prospectus forming a part thereof
                  or any amendments or supplements thereto do not contain
                  current and updated information or contain any untrue
                  statement of material fact or omit to state any material fact
                  required to be stated therein or necessary to make the
                  statements therein, in light of the circumstances in which
                  they were made, not misleading, Aetrium Incorporated will
                  promptly (and in any event within five (5) business days of
                  receipt of the Sale Notice for any Holder entering into a
                  Right of First Refusal Agreement and otherwise within one (1)
                  business day of receipt of the Sale Notice) notify the Holder
                  of such determination, and within thirty (30) days thereafter
                  will prepare and file with the Commission such amendments or
                  supplements thereto as may be necessary so that the
                  Registration Statement, the prospectus forming a part thereof
                  and any amendments and supplements thereto contain current and
                  updated information and do not contain any untrue statement of
                  material fact or omit to state any material fact required to
                  be stated therein or necessary to make the statements therein,
                  in light of the circumstances in which they were made, not
                  misleading. Promptly after any such amendments or supplements
                  have been filed and, if applicable, declared effective,
                  Aetrium Incorporated will notify the Holder that such Holder
                  may sell the Registrable Securities. If the Holder does not
                  sell the Registrable Securities within thirty (30) days after
                  such notification from Aetrium Incorporated, however, the

other provision in this Article VIII to the contrary, Holders are prohibited

the meaning of the Securities Act, from and against, and will reimburse such
Holder and each such controlling person with respect to, any and all loss,
damage, liability, cost and expense to which such Holder or any such controlling
person may become subject under the Securities Act or otherwise, insofar as such
losses, damages, liabilities, costs or expenses are caused by any untrue
statement or alleged untrue statement of any material fact contained in such
Registration Statement, any prospectus forming a part thereof or any amendments
or supplements thereto, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading; provided, however, that Aetrium
Incorporated will not be liable in any such case to the extent that any such
loss, damage, liability, cost or expense arises out of or is based upon (1) an
untrue statement or alleged untrue statement or omission or alleged omission so
made in conformity with information furnished by such Holder or such controlling
person in writing specifically for use in the preparation thereof, or (2) the
failure of such Holder to deliver a prospectus and any amendments or supplements
thereto in accordance with the requirements of this Article VIII and the
Securities Act.

                  (b) Seller and each holder jointly and severally will
indemnify and hold harmless Aetrium Incorporated, its directors and officers,
and any controlling person from and against, and will reimburse Aetrium
Incorporated, its directors and officers, and any controlling person with
respect to, any and all loss, damage, liability, cost or expense to which
Aetrium Incorporated or any controlling person may become subject under the
Securities Act or otherwise, insofar as such losses, damages, liabilities, costs
or expenses are caused by any untrue or alleged untrue statement of any material
fact contained in such Registration Statement, any prospectus forming a part
thereof or any amendment or supplement thereto, or arise out of or are based
upon the omission or the alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, in each case
to the extent, but only to the extent, that any such loss, damage, liability,
cost or expense arises out of or is based upon (1) an untrue statement or
alleged untrue statement or omission or alleged omission made in reliance upon
and in strict conformity with written information furnished by such Holder
specifically for use in the preparation thereof, or (2) the failure of such
Holder to deliver a prospectus and any amendments or supplements thereto in
accordance with the requirements of this Article VIII and the Securities Act.

                  (c) Promptly after receipt by an indemnified party pursuant to
the provisions of Section 8.5(a) or (b) hereof of notice of the commencement of
any action involving the subject matter of the foregoing indemnity provisions,
such indemnified party will, if a claim thereof is to

                                       25

<PAGE>


be made against the indemnifying party pursuant to the provisions of such
Section 8.5(a) or (b), promptly notify the indemnifying party of the
commencement thereof. In case such action is brought against any indemnified
party and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will have the right to participate in, and, to the extent
that it may wish, jointly with any other indemnifying party similarly notified,
to assume the defense thereof, with counsel reasonably satisfactory to such
indemnified party; provided, however, that if the defendants in any action
include both the indemnified party and the indemnifying party and the
representation of both parties by the same counsel would be inappropriate due to
a conflict of interest between them, the indemnified party or parties will have
the right to select separate counsel to participate in the defense of such
action on behalf of such indemnified party or parties. After notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party pursuant to the provisions of such Section 8.5(a) or (b) for any legal or
other expense subsequently incurred by such indemnified party in connection with
the defense thereof other than reasonable costs of investigation, unless (1) the
indemnified party has employed counsel in accordance with the proviso of the
preceding sentence, (2) the indemnifying party has not employed counsel
reasonably satisfactory to the indemnified party to represent the indemnifying
party within a reasonable time after the notice of the commencement of the
action, or (3) the indemnifying party has authorized the employment of counsel
for the indemnified party at the expense of the indemnifying party. It is
understood that the indemnifying party will not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm for all indemnified parties.

         8.6 Cooperation; Information by Holders. Each Holder of Registrable
Securities covered by the Registration Statement agrees to cooperate with all
reasonable requests by Aetrium Incorporated necessary to effectuate the purposes
of this Article VIII, including providing Aetrium Incorporated on a timely basis
with any required notices and with all information necessary in connection with
any registration or compliance described herein.

         8.7 Transfer of Registration Rights. The registration rights provided
for herein may not be transferred or assigned in connection with the sale or
transfer of the Registrable Securities without the written consent of Aetrium
Incorporated. In the event Seller is a Share Designee, consent will not be
withheld for a transfer of registration rights with respect to Shares for which
Seller is a Share Designee to a shareholder of Seller in connection with
distribution of such Shares to such shareholder.

         8.8 Termination of Registration Rights. The registration rights
described herein will terminate upon expiration of the Effectiveness Period.

                                   ARTICLE XI
                       INDEMNIFICATION AND RELATED MATTERS

         11.1 Indemnification by Seller. Subject to the provisions of this
Article XI, Seller will indemnify and hold harmless Buyer and each director,
officer, employee, stockholder, partner or affiliate thereof from and against
any and all damages, loss, cost or expense (including reasonable attorney's fees
and expenses actually incurred) (collectively, "LOSS") suffered by reason of,
arising out of or resulting from (a) any misrepresentation or breach of warranty
made by Seller in or pursuant to this Agreement (other than, with respect to any
such director, officer or employee who is an officer or director of Seller on
the date of this Agreement, any such misrepresentation or breach of warranty
known to such officer or director on the Closing Date), (b) any failure by
Seller to fulfill any covenants or agreements under this Agreement, or (c) any
and all liabilities of Seller not expressly assumed by Buyer hereunder, or third
party claims therefor.

         11.2 Indemnification by Buyer. Buyer will indemnify and hold harmless
Seller and its officers and directors from and against any and all Loss suffered
by reason of, arising out of or resulting from (a) any material
misrepresentation or breach of warranty made by Buyer in or pursuant to this
Agreement, (b) any failure by Buyer to fulfill any covenants or agreements under
this Agreement, or (c) any and all Assumed Liabilities, or third party claims
therefor.

         11.3 Notice of Indemnification. In the event any legal proceeding is
threatened or instituted or any claim or demand is asserted by any person
(including a party hereto) in respect of which payment may be sought by one
party hereto from the other party under the provisions of this Article XI, the
party seeking indemnification (the "INDEMNITEE") will promptly cause written
notice of the assertion of any such claim of which it has knowledge which is
covered by this indemnity to be forwarded to the other party (the "INDEMNITOR").
Any notice of a claim by reason of any of the representations, warranties or
covenants contained in this Agreement will state specifically the
representation, warranty or covenant with respect to which the claim is made,
the facts giving rise to an alleged basis for the claim, and the amount of the
liability asserted against the Indemnitor by reason of the claim.

         11.4 Indemnification Procedure for Third-Party Claims. In the event of
the initiation of any legal proceeding against an Indemnitee by a third party,
the Indemnitor will have the absolute right after the receipt of notice, at its
option and at its own expense, to be represented by counsel of its choice, and
to defend against, negotiate, settle or otherwise deal with any proceeding,
claim, or demand which relates to any loss, liability or damage indemnified
against hereunder; provided, however, that the Indemnitee may participate in any
such proceeding with counsel of its choice and at its expense. The parties will
cooperate fully with each other in connection with the defense, negotiation or
settlement of any such legal proceeding, claim or demand. To the extent the
Indemnitor elects not to defend such proceeding, claim or demand, and the
Indemnitee defends against or otherwise deals with any such proceeding, claim or
demand, the Indemnitee may retain

                                       29

<PAGE>



counsel, at the expense of the Indemnitor, and control the defense of such
proceeding. Neither the Indemnitor nor the Indemnitee may settle any such
proceeding without the consent of the other party, such consent not to be
unreasonably withheld. After any final judgment or award has been rendered by a
court, arbitration board or administrative agency of competent jurisdiction and
the time in which to appeal therefrom has expired, or a settlement has been
consummated, or the Indemnitee and the Indemnitor have arrived at a mutually
binding agreement with respect to each separate matter alleged to be indemnified
by the Indemnitor hereunder, the Indemnitee will forward to the Indemnitor
notice of any sums due and owing by it with respect to such matter and the
Indemnitor will pay all of the sums so owing to the Indemnitee by wire transfer,
certified or bank cashier's check within thirty (30) days after the date of such
notice. Notwithstanding the foregoing, the provisions of Section 8.5 will govern
all indemnification claims made thereunder.

         11.5 Survival of Representations, Warranties and Covenants. The
representations and warranties made in this Agreement and the covenants and
agreements contained herein to be performed or complied with at or prior to the
Closing Date will survive for twenty-four (24) months after the Closing Date,
and no legal action [or arbitration proceeding] may be commenced thereafter with
respect to any alleged breach thereof.

         11.6 Exclusive Remedy. Except for equitable relief as provided under
Section 7.3, the exclusive remedy available to a party hereto in respect of the
matters covered by Section 10.1 or Section 10.2 hereof is to proceed in the
manner and subject to the limitations contained in this Article X (or Section
8.5 where applicable), provided that nothing herein will limit the rights and
remedies of Buyer under the Delaware General Corporation Law and common law
relevant thereto against the shareholders of Seller with respect to the
liabilities and obligations of Seller hereunder, and provided further that
nothing will limit the rights and remedies of each party with respect to any
intentionally wrongful acts of the other party.


                                   ARTICLE XII
                          TERMINATION PRIOR TO CLOSING

         12.1 Termination. This Agreement may be terminated at any time prior to
the Closing:

                  (a) by the mutual written consent of Buyer and Seller; or

                  (b) by either Seller or Buyer in writing (provided the
conditions to such party's obligations stated in the applicable sections of
Article IX or X are not then satisfied or waived) if the Closing has not
occurred on or before April 30, 1998; or

                  (c) by either Seller or Buyer in writing, if there is in
effect a non-appealable order of a court of competent jurisdiction prohibiting
the consummation of the transactions contemplated hereby.

         12.2 Effect on Obligations. Termination of this Agreement pursuant to
this Article will terminate all obligations of the parties hereunder, provided,
however, that termination pursuant to

                                       30

<PAGE>


clause (b) of Section 12.1 hereof will not relieve any defaulting or breaching
party from any liability to the other party hereto, and provided, further, that
the provisions of this Section 12.2 and Article XIII will survive termination of
this Agreement.


                                  ARTICLE XIII
                                  MISCELLANEOUS

         13.1 Entire Agreement. This Agreement (including the Exhibits and the
Disclosure Schedule delivered pursuant hereto) constitutes the entire agreement
of the parties with respect to the matters provided for herein and supersedes
all prior and contemporaneous agreements, understandings, negotiations and
discussions, whether oral or written, of the parties. No amendment, modification
or alteration of the terms or provisions of this Agreement will be binding
unless the same is in writing and duly executed by the parties hereto.

         13.2 Successors and Assigns. The terms and conditions of this Agreement
will inure to the benefit of and be binding upon the respective successors and
permitted assigns of the parties hereto. This Agreement may not be assigned by
any party without the prior written consent of the other party hereto, except
that Buyer may, at its election, assign its rights under this Agreement to any
direct or indirect wholly-owned subsidiary. Notwithstanding the foregoing, no
assignment of this Agreement or any of the rights or obligations hereof by Buyer
will relieve Buyer of its obligations under this Agreement to Seller and, upon
any such assignment, the representations, warranties, covenants and agreements
contained in this Agreement will be deemed to have been made by Buyer's assignee
as well as by Buyer. Any attempted assignment of this Agreement contrary to the
terms hereof will be null and void and of no force or effect.

         13.3 Counterparts. This Agreement may be executed in one or more
counterparts, each of which will for all purposes be deemed to be an original
and all of which will constitute the same instrument.

         13.4 Headings. The headings of the articles and sections of this
Agreement are included for convenience only and will not be deemed to constitute
part of this Agreement or to affect the construction hereof.

         13.5 Modifications and Waivers. No waiver of any of the terms or
conditions of this Agreement or any right hereunder will be effective unless
given in a signed writing by the party entitled to the benefits thereof. No
waiver of any of the provisions of this Agreement or any rights hereunder will
be deemed to or will constitute a waiver of any other provisions hereof or
rights hereunder (whether or not similar). No failure or delay on the part of a
party in exercising any right hereunder will operate as a waiver of, or impair,
any such right. No single or partial exercise of any such right will preclude
any other or further exercise thereof or the exercise of any other right.

         13.6 Broker's Fees. Each of the parties hereto represents and warrants
to the other that it has had no dealings with any broker or finder in connection
with the transactions contemplated by this Agreement. Seller will indemnify and
hold harmless Buyer from and against any and all liability 


                                       31

<PAGE>


to which Buyer may be subjected by reason of any broker's or finder's fee with
respect to the transactions contemplated hereby to the extent such fee is
attributable to any action undertaken by or on behalf of Seller. Buyer will
indemnify and hold harmless Seller from and against any and all liability to
which Seller may be subjected by reason of any broker's or finder's fee with
respect to the transaction contemplated hereby to the extent such fee is
attributable to any action undertaken by or on behalf of Buyer.

         13.7 Expenses.

                  (a) Seller will pay all costs and expenses incurred by or on
behalf of Seller, and Buyer will pay all costs and expenses incurred by or on
behalf of it, in connection with this Agreement, the negotiations in connection
herewith, and the transactions contemplated hereby, including without limitation
fees and expenses of their respective brokers, finders, financial consultants,
accountants and counsel, and including with respect to Seller all costs and
expenses incurred in providing audited financial statements as required under
Section 5.4.

                  (b) If any dispute between Seller and Buyer, either occurring
under, relating to or in connection with any of the provisions of this
Agreement, is submitted to a court, arbitrator or other appropriate tribunal,
then all costs and expenses of the parties (including tribunal costs and
reasonable attorneys' fees) will be paid by the party against whom a
determination by such court, arbitrator or other tribunal is made or, in the
absence of a determination wholly against one party, as such court, arbitrator
or other tribunal directs.

         13.8 Notices. Any notice, request, instruction or other document to be
given hereunder by any party hereto to any other party will be in writing and

provided will be conclusively presumed to have been duly given to the party to
which it is addressed at the close of business, local time of the recipient, on
the third day after the day it is so placed in the mail.

         13.9 Arbitration. Subject to the last sentence of this Section, any
controversy or claim arising out of or relating to any provisions of this
Agreement or the breach hereof, unless resolved by mutual agreement of the
parties, will be finally settled by arbitration in accordance with the
Commercial Arbitration Rules of the American Arbitration Association in effect
on the effective date of this Agreement by a single arbitrator appointed in
accordance with said Rules. The determination of the arbitrator will be final
and binding upon the parties to the arbitration and judgment upon the award
rendered by the arbitrator will be entered in any court of competent
jurisdiction. The place of arbitration will be Minneapolis, Minnesota.
Notwithstanding the foregoing, either party may seek injunctive relief with
respect to any controversy or claim arising out of or relating to any provisions
of this Agreement in any court of competent jurisdiction.

          13.10 Governing Law; Consent to Jurisdiction. This Agreement will be
construed in accordance with and governed by the laws of the state of Minnesota
applicable to agreements made and to be performed in such jurisdiction without
reference to conflicts of law principles. Each of Buyer and Seller irrevocably
consents that any legal action or proceeding against it under, arising out of or
in any manner relating to this Agreement or any other agreement, document or
instrument arising out of or executed in connection with this Agreement may be
brought only in an arbitration proceeding as provided in Section 13.9 or in a
court of the state of Minnesota or in the United States District Court for
Minnesota. Each of Buyer and Seller by the execution and delivery of this
Agreement, expressly and irrevocably assents and submits to the personal
jurisdiction of the 

                                       33

<PAGE>

arbitrators selected pursuant to Section 13.9 or any of such courts in any such
action or proceeding. Each of Buyer and Seller further irrevocably consents to
the service of any complaint, summons, notice or other process relating to any
such action or proceeding by delivery thereof to it by hand or by mail in the
manner provided for in Section 13.8 hereof. Each of Buyer and Seller hereby
expressly and irrevocably waives any claim or defense in any action or
proceeding based on any alleged lack of personal jurisdiction, improper venue or
forum non conveniens or any similar basis.

         13.11 Confidentiality and Nonsolicitation.

                  (a) "SELLER CONFIDENTIAL INFORMATION" means information
received by Buyer or any of its agents, directors, officers, employees, counsel,
consultants, affiliates or advisors ("REPRESENTATIVES") from Seller or its
Representatives in the course of Buyer's investigation of Seller and negotiation
and performance of this Agreement, including without limitation trade secret and
other proprietary technical, financial and other information relating to the
Business or Seller's products, whether past, present or anticipated, including
information about Seller's research, development, manufacturing, purchasing,
accounting, engineering, marketing, selling or servicing, and any analyses,
compilations, studies, materials, memoranda, data, notes or documents prepared
by Buyer or its Representatives and concerning such information received by
Buyer or its Representatives.

                  (b) The Seller Confidential Information will be kept
confidential and will not, without the prior written consent of Seller, be
disclosed by Buyer or its Representatives in any manner whatsoever, in whole or
in part, and will not be used by Buyer or its Representatives other than in
connection with the transactions contemplated hereunder. The Seller Confidential
Information will be disclosed by Buyer and its Representatives only to Buyer's
Representatives who have a "need to know" such Seller Confidential Information
and who have been informed by Buyer of the confidential nature of the Seller
Confidential Information and who have first agreed to be bound by the terms and
conditions of this Section 13.11.

                  (c) Immediately upon termination of this Agreement, the Seller
Confidential Information which consists of analyses, compilations, studies,
material, memoranda, data, notes or other documents prepared by Buyer or its
Representatives in that capacity will be destroyed and such destruction will be
certified in writing to Seller by an authorized officer supervising such
destruction, and all other Seller Confidential Information will be returned to
Seller without Buyer retaining any copies thereof.

                  (d) In the event that Buyer or anyone to whom Buyer transmits
the Seller Confidential Information pursuant to the provisions of this Section
13.11 becomes legally compelled to disclose any of the Seller Confidential
Information, Buyer will provide Seller with prompt notice before such Seller
Confidential Information is disclosed so that Seller may seek a protective order
or other appropriate remedy and/or waive compliance with the provisions of this
Section 13.11. In the event that such protective order or other remedy is not
obtained, Buyer will furnish only that portion of the Seller Confidential
Information which Buyer is advised by written reasonable opinion of counsel is
legally required and will exercise Buyer's best efforts to assist Seller in
obtaining a 


                                       34

<PAGE>


protective order or other reliable assurance that confidential treatment will be
accorded to the Seller Confidential Information that is disclosed.

                  (e) Nothing contained in this Section 13.11 will in any way
restrict or impair Buyer's right to use, disclose or otherwise deal with (1)
Seller Confidential Information which at the time of its disclosure is, or which
thereafter becomes through no fault of Buyer or its Representatives, part of the
public domain by publication or otherwise, and (2) Seller Confidential
Information which Buyer can show was in Buyer's possession or the possession of
one or more of its Representatives at the time of disclosure, and was not
acquired, directly or indirectly, under any secrecy obligation to Seller or
another party.

                  (f) The provisions of this Section 13.11 will lapse and be of
no further force or effect upon Closing.

         13.12 Public Announcements. Neither Seller (nor any of its affiliates)
nor Buyer (nor any of its affiliates) will make any public statements, including
without limitation any press releases, with respect to this Agreement and the
transactions contemplated hereby without the prior written consent of the other
party (which consent may not be unreasonably withheld), except as may be
required by law and except that the party required to make such announcement
will, whenever practicable, consult with the other party concerning the timing
and content of such announcement before such announcement is made.

         13.13 Severability. If any provision hereof is held by any court of
competent jurisdiction to be illegal, void or unenforceable, such provision will
be of no force and effect, but the illegality or unenforceability will have no
effect upon and will not impair the enforceability of any other provision of
this Agreement.

         13.14 Definition of Seller's Knowledge. For purposes of this Agreement,
"KNOWLEDGE" of Seller includes only matters known or which would have been known
after due inquiry by Keith E. Williams.

         13.15 Disclosure Schedule; Buyer's Knowledge; Effect on Seller
Representations and Warranties; Effect of Materiality Qualification. Nothing in
the Disclosure Schedule will be deemed adequate to disclose an exception to a
representation or warranty of Seller made herein, unless the Disclosure Schedule
identifies the exception with reasonable particularity and describes the
relevant facts in reasonable detail. Without limiting the generality of the
foregoing, the mere listing (or inclusion of a copy) of a document or other item
will not be deemed adequate to disclose an exception to a representation or
warranty made herein (unless the representation or warranty has to do with the
existence of the document or other item itself). Disclosures in any schedule of
the Disclosure Schedule will constitute disclosure only for purposes of such
schedule's counterpart section herein, and will not constitute disclosure for
purposes of any other section of this Agreement or any exhibit to or other
writing which is designated herein as being part of this Agreement. No
disclosure whatsoever during Buyer's due diligence investigation of Seller will
constitute an enlargement or restriction of the warranties or representations of
Seller hereunder or exceptions thereto beyond those specifically set forth in
this Agreement and the Disclosure Schedule. No

                                       35

<PAGE>


representation or warranty of Seller will be deemed waived in whole or part, and
no Loss resulting from the breach thereof will be reduced, by reason of the fact
that Buyer or its representatives knew or should have known on or before the
Closing Date that such representation or warranty is or might be inaccurate in
any respect. If any representation or warranty of Seller that is qualified by
materiality (including a Material Adverse Effect) is breached after giving
effect to such materiality qualification, then Loss resulting from such breach
includes all Loss resulting from such breach from first dollar as if there were
no such materiality qualification.

         13.16 No Third Party Beneficiaries. All Holders are intended
beneficiaries of the provisions of Article VIII, which provisions will inure to
the benefit thereof and be enforceable thereby. Except for the foregoing or as
otherwise expressly permitted by this Agreement, nothing in this Agreement will
confer any rights upon any person or entity which is not a party or permitted
assignee of a party to this Agreement.

         13.17 Rule of Construction. The parties hereto acknowledge and agree
that each has negotiated and reviewed the terms of this Agreement, assisted by
such legal and tax counsel as they desired, and has contributed to its
revisions. The parties further agree that the rule of construction that any
ambiguities are resolved against the drafting party will be subordinated to the
principle that the terms and provisions of this Agreement will be construed
fairly as to all parties and not in favor of or against any party.


         IN WITNESS WHEREOF, each of the parties hereto has caused this
Agreement to be executed on its behalf as of the date first above written.

RE:  REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

We have acted as counsel to Aetrium Incorporated, a Minnesota corporation (the
"Company"), in connection with the registration by the Company of the resale of
900,000 shares of the Company's Common Stock, $.001 par value per share (the
"Shares"), pursuant to the Company's Registration Statement on Form S-3 filed
with the Securities and Exchange Commission on April 7, 1998 (the "Registration
Statement") on behalf of the certain selling shareholders named therein (the
"Selling Shareholders").

In acting as counsel for the Company and arriving at the opinions expressed
below, we have examined and relied upon originals or copies, certified or
otherwise identified to our satisfaction, of such records of the Company,
agreements and other instruments, certificates of officers and representatives
of the Company, certificates of public officials and other documents as we have
deemed necessary or appropriate as a basis for the opinions expressed herein. In
connection with our examination, we have assumed the genuiness of all
signatures, the authenticity of all documents tendered to us as originals, the
legal capacity of all natural persons and the conformity to original documents
of all documents submitted to us as certified or photostatic copies.

Based on the foregoing, and subject to the qualifications and limitations stated
herein, it is our opinion that:

1.       The Company had the corporate authority to issue the Shares in the
         manner and under the terms set forth in the Registration Statement.

2.       The Shares being registered for resale by the Selling Shareholder under
         the Registration Statement have been duly authorized and are validly
         issued, fully paid and nonassessable.
