                                  THE COMPANY
 
    SurModics, Inc. ("SurModics" or the "Company") is a leading provider of
surface modification solutions to the medical device industry. The Company's
primary focus is the commercialization of its patented PhotoLink process through
third-party licensing arrangements. PhotoLink is a versatile, easily applied,
light-activated coating technology that modifies medical device surfaces by
creating covalent bonds between those surfaces and a variety of chemical agents.
Through the PhotoLink process, these chemical agents can impart many
performance-enhancing characteristics, such as lubricity, hemocompatibility,
infection resistance and drug delivery, onto the surface of a medical device
without materially changing the dimensions or physical properties of the device.
The Company believes that medical device manufacturers who utilize the Company's
technology are able to significantly improve the performance of their products
and, in many cases, differentiate their products in a highly competitive
marketplace.
 
    The Company focuses on providing high value-added surface modification
solutions to a variety of medical device markets and product categories.
Examples of products in the market or under development that incorporate the
PhotoLink technology include interventional cardiology catheters, vascular
stents, interventional neurology catheters, guide wires and shunts, cardiac
rhythm management devices, and urological and gynecological devices. The surface
properties created by the PhotoLink technology have greatly reduced treatment
times in catheter-based vascular procedures and have shown the potential to
enhance the long-term performance of implantable devices by improving infection
resistance and promoting host cell attachment, growth and subsequent tissue
integration. The Company believes further opportunities exist to commercialize
its PhotoLink technology for other market applications, such as biomolecule
immobilization for use in the emerging field of DNA-based diagnostics.
 
    SurModics believes its PhotoLink technology has many advantages over other
competing surface modification technologies. First, the PhotoLink technology can
be applied to many different kinds of surfaces, which allows manufacturers a
high degree of flexibility in designing their products. Second, the PhotoLink
technology can immobilize a variety of chemical, pharmaceutical and biological
agents, thereby imparting many different performance-enhancing characteristics
to the device being coated. Third, the PhotoLink technology provides the medical
device manufacturer with the ability to combine multiple surface-enhancing
characteristics on the same device. Finally, the PhotoLink process is relatively
simple and does not subject the medical devices to harsh chemical, pressure or
temperature conditions during the coating process as is the case with some
competing technologies. PhotoLink coatings are compatible with all generally
accepted sterilization processes and the PhotoLink process does not require
expensive, specialized manufacturing equipment. In addition, SurModics' customer
service includes free proof-of-concept studies for potential applications,
coating optimization for specific licensee applications, transfer of the
technology to licensee manufacturing facilities, and assistance during the FDA
approval process for PhotoLink coated devices.
 
    The Company has commercialized its PhotoLink technology through licensing
arrangements with medical device manufacturers which apply the PhotoLink
coatings to their own products. The Company believes this approach allows it to
focus its resources on further development of its technology and expansion of
its licensing activities, while leveraging the established manufacturing, sales
and marketing
 
                                       3
<PAGE>
capabilities of its licensees. Revenues from these arrangements include initial
license fees, minimum royalties and earned royalties based on a percentage of
licensees' product sales. The Company currently has license agreements with 32
companies covering 106 different applications, of which 58 are generating
royalty revenues for the Company. Licensees of the PhotoLink technology include
Cook Incorporated, Cordis Corporation (a Johnson & Johnson company), Medtronic
PS Medical, Pacesetter, Inc. (a St. Jude Medical, Inc. company), Perclose, Inc.,
Sulzer Carbomedics (a division of Sulzer Medica USA Inc.) and Target
Therapeutics, Inc. (a subsidiary of Boston Scientific Corporation).
 
    In addition to licensing its PhotoLink technology, the Company also licenses
certain diagnostic technology to Abbott Laboratories for use with rapid
point-of-care diagnostic tests, such as pregnancy and strep tests. The Company
also manufactures and sells the chemical reagents used in the PhotoLink process
and stabilization products used to extend the shelf-life of immunoassay
diagnostic tests.
 
    The Company was incorporated under the laws of the State of Minnesota in
June 1979. The Company's executive offices are located at 9924 West 74th Street,
Eden Prairie, Minnesota 55344, its telephone number is (612) 829-2700 and its

                                  RISK FACTORS
 
    THE COMMON STOCK OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK. THIS
PROSPECTUS INCLUDES CERTAIN FORWARD-LOOKING STATEMENTS WHICH REFLECT THE
COMPANY'S PLANS, ESTIMATES AND BELIEFS. THE COMPANY'S ACTUAL RESULTS COULD
DIFFER MATERIALLY FROM THOSE DISCUSSED IN THE FORWARD-LOOKING STATEMENTS.
FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES ARE DISCUSSED IN THE
FOLLOWING RISK FACTORS AND ELSEWHERE IN THIS PROSPECTUS. IN EVALUATING AN
INVESTMENT IN THE COMMON STOCK, PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER
THE FOLLOWING RISK FACTORS AND OTHER INFORMATION CONTAINED IN THIS PROSPECTUS.
 
DEPENDENCE ON ROYALTY REVENUES
 
    The principal element of the Company's strategy is to enter into licensing
arrangements with medical device companies that manufacture products
incorporating the Company's technology. For the fiscal years ended September 30,
1997 and 1996, the Company derived approximately 38.4% and 37.9% of its
revenues, respectively, from royalties. The Company does not currently
manufacture, market or sell its own medical devices nor does it intend to do so
in the foreseeable future. Thus, the Company's prospects are substantially
dependent on the receipt of royalties from licensees of its technology. The
amount and timing of such royalties are, in turn, dependent on the ability of
the Company's licensees to successfully gain regulatory approval for, market and
sell products incorporating the Company's technology. Failure of certain
licensees to gain regulatory approval or market acceptance for such products
could have a material adverse effect on the Company's business, financial
condition and results of operations. Although the Company believes that its
licensees have an economic motivation to market products containing the
Company's technology, the amount and timing of resources to be devoted by them
to marketing and the ultimate commercial success of such medical devices are not
within the control of the Company. Hence, the amount and timing of royalty
payments received by the Company will fluctuate, and such fluctuations could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
    Under the Company's standard license agreements, licensees can abandon the
Company's technology for any reason upon prior written notice, typically
required at least 90 days before termination. Existing and potential licensees
have no obligation to deal exclusively with the Company in obtaining surface
modification technology and may pursue parallel development or licensing of
competing surface modifications, on their own or with third parties. A decision
by a licensee to abandon or terminate one or more of its products coated through
the PhotoLink process or to otherwise terminate its relationship with the
Company could materially adversely affect the Company's business, financial
condition and results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and "Business--Current
Licensing Arrangements."
 
NEED TO EXPAND LICENSING BASE; UNCERTAINTY OF MARKET ACCEPTANCE
 
    The Company intends to continue pursuing a strategy of licensing its
technology to a diversified base of medical device manufacturers, thereby
expanding its licensing base for the PhotoLink technology. The Company's success
will depend, in part, on its ability to attract new licensees and to enter into
agreements for additional applications with existing licensees. There can be no
assurance that the Company can successfully expand its licensing base or that
such expansion will result in increased commercialization of licensed
applications. While certain applications of SurModics' PhotoLink technology have
gained acceptance in some segments of the medical device industry, the Company
is in the early stages of adapting the technology for a broader base of medical
applications with additional performance-enhancing characteristics. The
Company's ability to expand its licensing base will depend, in part, on its
ability to develop and market new applications for its PhotoLink technology in
its target markets. However, certain of the Company's existing licenses are
exclusive with respect to certain medical devices, which could restrict the
Company's ability to license the same technology to another entity for a similar
or competitive purpose. There can be no assurance that the Company will be able
to identify, develop and adapt its PhotoLink
 
                                       6
<PAGE>
technology for new applications in a timely and cost effective manner, that new
applications will be licensed by the Company on favorable terms, that such
applications will be accepted by manufacturers in the Company's target markets,
or that products incorporating new applications will gain regulatory approval,
be commercialized or gain market acceptance. Delays in developing new or
enhancing existing PhotoLink applications or the failure of such applications or
potential licensees' products to gain market acceptance could have an adverse
effect on the Company's business, financial condition and results of operations.
See "Business--Strategy," "Business--Research and Development" and
"Business--Government Regulation."
 
COMPETITION AND RISK OF TECHNOLOGICAL OBSOLESCENCE
 
    The Company operates in a highly competitive and rapidly evolving field and
new developments are expected to continue at a rapid pace. The Company's success
depends, in part, upon its ability to maintain a competitive position in the
development of technologies and products in its areas of focus. The Company's
PhotoLink technology competes with technologies developed by Biocompatibles
International plc, Carmeda (a division of Norsk Hydro USA, Inc.), Specialty
Coatings Systems, Spire Corporation and STS Biopolymers Inc., among others. In
addition, many medical device manufacturers have developed or are engaged in
efforts to develop surface modification technologies generally for use on their
own products. Competition may also result from development efforts by existing
and potential licensees who have no obligation to deal exclusively with the
Company in utilizing or developing surface modification technologies. Many of
the Company's existing and potential competitors (including medical device
manufacturers pursuing coating solutions through their own research and
development efforts) have substantially greater financial and technical
resources and production and marketing capabilities than the Company. There can
be no assurance that the Company will be able to compete effectively with such
competitors. Furthermore, there can be no assurance that new products or
technologies developed by others, or the emergence of new industry standards,
will not render the Company's products or technologies or licensees' products
incorporating the Company's technologies noncompetitive or obsolete. Any new
technologies which make the Company's PhotoLink technology less competitive or
obsolete would have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business--Competition."
 
HISTORY OF LOSSES AND ACCUMULATED DEFICIT
 
    The Company has incurred net losses in each year since inception, except for
the year ended September 30, 1997, during which the Company recorded operating
income of $37,000 and net income of $236,000. As of September 30, 1997, the
Company had an accumulated deficit of $8.2 million. Losses have resulted
principally from costs incurred in connection with the Company's research and
development activities and from general and administrative costs associated with
the Company's operations. Historically, operations have been predominately
funded with government grants and equity offerings. The Company's revenues may
fluctuate from quarter to quarter and year to year primarily as a result of
fluctuations in the recognition of initial license fees and royalty revenue. The
Company's ability to generate significant revenues and maintain profitability
will depend, in large part, on the ability of the Company to enter into
additional license agreements and on the ability of its licensees to
successfully commercialize products incorporating the Company's technologies. No
assurance can be given that the Company will generate significant revenue growth
or maintain profitability. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
DEPENDENCE ON PATENTS AND PROPRIETARY RIGHTS
 
    The Company's success depends, in large part, on its ability to obtain and
maintain patents, maintain trade secret protection, operate without infringing
on the proprietary rights of third parties and protect its proprietary rights
against infringement by third parties. The Company has been granted U.S. and
foreign
 
                                       7
<PAGE>
patents and has U.S. and foreign patent applications pending related to its
PhotoLink technology. There can be no assurance that any pending patent
application will be approved, that the Company will develop additional
proprietary technology that is patentable, that any patents issued to the
Company will provide the Company with competitive advantages or will not be
challenged or invalidated by any third parties or that the patents of others
will not prevent the commercialization of products incorporating the Company's
technology. Furthermore, there can be no assurance that others will not
independently develop similar technology, duplicate any of the Company's
technology or design around the Company's patents. There can also be no
assurance that the Company's trade secrets or confidentiality agreements with
potential licensees or other parties will provide meaningful protection for the
Company's unpatented proprietary information.
 
    The commercial success of the Company also will depend, in part, on its
ability to avoid infringing patent or other intellectual property rights of
third parties. There has been substantial litigation regarding patent and other
intellectual property rights in the medical device industry, and intellectual
property litigation may be used against the Company as a means of gaining a
competitive advantage. Intellectual property litigation is complex,
time-consuming and expensive, and the outcome of such litigation is difficult to
predict. If the Company were found to be infringing any third-party patent or
other intellectual property right, the Company could be required to pay
significant damages, alter its products or processes, obtain licenses from
others or cease commercialization of its products and processes. If the Company
is required to obtain any licenses, there can be no assurance that the Company
will be able to do so on commercially favorable terms, if at all. The Company's
failure to obtain any such license on commercially favorable terms could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
    Patent litigation may also be necessary to enforce any patents issued or
licensed to the Company or to determine the scope and validity of third-party
proprietary rights. If patent applications are filed in the U.S. that claim
technology also claimed by the Company, the U.S. Patent and Trademark office may
declare an interference proceeding to determine priority of invention which
could result in substantial cost to the Company, even if the eventual outcome is
favorable to the Company. An adverse outcome of any such litigation or
interference proceeding could subject the Company to significant liabilities to
third parties, require disputed rights to be licensed from third parties or
require the Company to cease using its technology. Any action to defend or
prosecute intellectual property would be costly and result in significant
diversion of the efforts of the Company's management and technical personnel,
regardless of outcome, and could have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business--Patents
and Proprietary Rights" and "Use of Proceeds."
 
DEPENDENCE ON KEY LICENSEE AND GOVERNMENT FUNDING
 
    Abbott Laboratories ("Abbott") and certain U.S. government agencies
accounted for 21% and 16% of the Company's revenues, respectively, for fiscal
1997 and 24% and 21% of the Company's revenues, respectively, for fiscal 1996.
The revenues from Abbott primarily represent royalties received by SurModics in
connection with an exclusive license granted to Abbott of the Company's patent
rights in a particular diagnostic format. This license currently expires in
2008, subject to extension or renewals of the life of the licensed patents, but
can be terminated earlier at any time by Abbott upon 90 days' prior written
notice. However, Abbott would then have no right to use such technology in any
of its diagnostic tests. There can be no assurance that revenues from Abbott or
any customer will continue at their historical levels. Loss of one or more of
the Company's current customers, particularly Abbott, could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
    The revenues from government agencies represent grants from such agencies
under the federal government's Small Business Innovative Research ("SBIR")
program. While the Company intends to continue to seek government grants to fund
some of its research and development efforts, there can be no assurance that the
Company will be successful in obtaining any future government grants. Although
 
                                       8
<PAGE>
government grants have represented a significant percentage of revenues in the
past, the Company believes that these revenues will decline slightly as an
absolute number and more significantly as a percentage of total revenue as the
Company continues its focus on commercializing its technology. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business--Other Products" and "Business--Research and Development."
 
PRODUCT LIABILITY AND INSURANCE
 
    The development and sale of medical devices and component products involves
an inherent risk of product liability claims. Although the Company expects that
devices incorporating its technologies and products will be manufactured by
others and sold under their own labels, there can be no assurance that product
liability claims will not be filed against the Company for such devices or that
such manufacturers will not seek indemnification or other relief from the
Company for any such claims. In addition, there can be no assurance that product
liability claims will not be filed directly against the Company with respect to
its own products. The Company currently maintains product liability insurance in
amounts which management believes are appropriate. There can be no assurance,
however, that product liability insurance will continue to be available to the
Company in the future on acceptable terms, if at all, or that, if available, the
coverages will be adequate to protect the Company against any future product
liability claims. Furthermore, the Company does not expect to be able to obtain
insurance covering its costs and losses as a result of any recall of its
products or devices incorporating the Company's technology due to alleged
defects, whether such recall is instituted by a device manufacturer or the
Company or required by a regulatory agency. A product liability claim, recall or
other claim with respect to uninsured liabilities or in excess of insured
liabilities could have a material adverse effect on the Company's business,
financial condition or results of operations.
 
DEPENDENCE UPON KEY PERSONNEL AND ABILITY TO ATTRACT QUALIFIED PERSONNEL
 
    The Company is highly dependent upon a number of key management and
technical personnel. The Company is also dependent upon its ability to attract
and retain additional highly qualified management and technical personnel. The
Company faces intense competition for qualified personnel, many of whom could be
subject to competing employment offers, and there can be no assurance that the
Company will be able to attract and retain such personnel. The Company does not
maintain key person insurance on any of its employees. The loss of the services
of one or more key employees or the failure to attract and retain additional
qualified personnel would have a material adverse effect on the Company's
business, financial condition and results of operations. See
"Business--Employees."
 
GOVERNMENT REGULATION
 
    Although PhotoLink technology itself is not directly regulated by the U.S.
Food and Drug Administration ("FDA"), the medical devices incorporating this
technology are subject to FDA regulation. The burden of securing FDA approval
for these medical devices rests with the Company's licensees (the medical device
manufacturers). However, the Company has prepared Device Master Files which may
be accessed by the FDA to assist it in its review of the applications filed by
the Company's licensees. Historically, most medical devices incorporating the
PhotoLink process have been subject to the FDA's 510(k) marketing approval
process, which typically lasts about six to nine months. Supplemental or full
pre-market approval ("PMA") reviews require a significantly longer period. Thus,
significantly more time will be required to commercialize applications subjected
to PMA review. Furthermore, sales of medical devices outside the U.S. are
subject to international regulatory requirements that vary from country to
country. The time required to obtain approval for sale internationally may be
longer or shorter than that required for FDA approval. There can be no assurance
that the Company's licensees will be able to obtain regulatory approval for
devices incorporating PhotoLink technology on a timely basis, or at all.
Regulatory approvals, if granted, may include significant limitations of the
indicated uses for which the product may be
 
                                       9
<PAGE>
marketed. In addition, product approval could be withdrawn for failure to comply
with regulatory standards or the occurrence of unforeseen problems following
initial marketing. Changes in existing regulations or adoption of new
governmental regulations or policies could prevent or delay regulatory approval
of products incorporating PhotoLink technology or subject the Company to
additional regulation. Failure or delay of licensees in obtaining FDA and other
necessary regulatory approval or clearance or the loss of previously obtained
approvals could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
    Certain of the Company's activities are regulated by federal and state
agencies in addition to the FDA. For example, activities in connection with
industrial applications of PhotoLink technology and waste disposal are subject
to regulation by the U.S. Environmental Protection Agency. Some PhotoLink
reagents must be registered with the agency with basic information filed related
to toxicity during the manufacturing process as well as the toxicity of the
final product. Failure to comply with existing or future regulatory requirements
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Government Regulation."
 
HAZARDOUS MATERIALS
 
    The Company's research activities sometimes involve the controlled use of
various hazardous materials. Although the Company believes that its safety
procedures for handling and disposing of such materials comply with the
standards prescribed by state and federal regulations, the risk of accidental
contamination or injury from these materials cannot be completely eliminated.
While the Company currently maintains insurance in amounts which it believes are
appropriate in light of the risk of accident, the Company could be held liable
for any damages that might result from any such event. Any such liability could
exceed the Company's insurance and available resources and could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business--Government Regulation."
 
NO PRIOR PUBLIC MARKET FOR COMMON STOCK; POSSIBLE VOLATILITY OF STOCK PRICE
 
    Prior to this offering, there has been no public market for the Common Stock
and there can be no assurance that an active public market for the Common Stock
will develop or be sustained after the offering. The initial public offering
price will be determined by negotiations between the Company and the
Underwriters and is not necessarily indicative of the market price at which the
Common Stock of the Company will trade after this offering. Market prices for
securities of medical technology companies can be highly volatile, and the
market has experienced significant price and volume fluctuations that are
unrelated to the operating performance of particular companies. Announcements of
the status or results of licensing agreements, development projects or
technological innovations by the Company or its competitors, developments
concerning proprietary rights, including patents and litigation matters,
government regulation, general market conditions, as well as quarterly
fluctuations in the Company's revenues and financial results and other factors,
may have a significant impact on the market price of the Common Stock. In
particular, the realization of any of the risks described in the "Risk Factors"
set forth in this Prospectus could have a dramatic and adverse impact on such

POTENTIAL ADVERSE MARKET IMPACT OF SHARES ELIGIBLE FOR FUTURE SALE
 
    Sales of substantial amounts of Common Stock (including shares issued upon
the exercise of outstanding options) in the public market following this
offering could have an adverse effect on the price of the Common Stock. Such
sales may also make it more difficult for the Company to sell equity or equity-
related securities in the future at a time and price that the Company would deem
appropriate. Upon completion of this offering, the Company will have 6,908,180
shares of Common Stock issued and outstanding. The 2,000,000 shares offered
hereby will be freely tradable following this offering, except for any shares
purchased by an "affiliate" of the Company, which will be subject to the
limitations of Rule 144 promulgated under the Securities Act of 1933, as amended
("Rule 144"). All officers and directors and
 
                                       10
<PAGE>
certain stockholders of the Company, owning an aggregate of 3,636,648 shares,
have entered into "lock-up" agreements, agreeing not to sell, transfer or
otherwise dispose of any shares of Common Stock without the consent of John G.
Kinnard and Company, Incorporated, as the representative of the several
Underwriters (the "Representative"), for a period of 180 days after the date of
this Prospectus. The Representative may waive these restrictions at any time in
its discretion. Taking such restrictions into account, in addition to the
2,000,000 shares of Common Stock offered hereby, (i) approximately 1,162,716
shares will be eligible for immediate sale on the date of this Prospectus in
accordance with Rule 144; (ii) approximately 17,428 additional shares will
become eligible for sale in the public market beginning 90 days after the date
of this Prospectus in accordance with Rule 144; and (iii) approximately
3,599,668 additional shares will be eligible for sale beginning 180 days after
the date of this Prospectus upon the expiration of the lock-up agreements,
subject, in certain cases, to volume and manner of sale limitations under Rule
144. As of the date of this Prospectus, options to purchase an aggregate of
1,239,800 shares of Common Stock are outstanding, with 915,200 of the shares
issuable upon exercise of such options subject to vesting requirements and
lock-up agreements. The remaining 324,600 shares issuable upon exercise of
outstanding options will become available for exercise and sale upon vesting and
effectiveness of Registration Statements on Form S-8, which the Company intends
to file following the expiration of the lock-up agreements referenced above.
Following the completion of this offering, the holders of an aggregate of
1,507,312 shares will also be entitled to registration rights with respect to
such shares. See "Shares Eligible for Future Sale."
 
ADVERSE EFFECT OF UNDESIGNATED STOCK AND ANTI-TAKEOVER PROVISIONS
 
    The authorized capital of the Company includes 5,000,000 shares of
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
one or more series and to fix the powers, preferences, rights and limitations of
such class or series, without seeking stockholder approval. The rights of the
holders of Common Stock will be subject to, and may be adversely affected by,
the rights of the holders of any preferred stock that may be created and issued
in the future. Furthermore, as a Minnesota corporation, the Company is subject
to provisions of the Minnesota Business Corporations Act ("MBCA") that could
have an anti-takeover effect on the Company. The Company may also consider
adopting additional anti-takeover measures. The authority of the Board to issue
undesignated stock and the anti-takeover provisions of the MBCA, as well as any
future anti-takeover measures adopted by the Company, may, in certain
circumstances, delay, deter or prevent takeover attempts and other changes in
control of the Company not approved by management and the Board of Directors. As
a result, the Company's stockholders may lose opportunities to dispose of their
shares at a premium over prevailing prices in the event of a change in control,
and the market price, voting and other rights of the holders of Common Stock may
also be affected. See "Description of Capital Stock."
 
DILUTION
 
    Purchasers of shares in this offering will incur immediate and substantial
dilution in the pro forma net tangible book value per share of their purchased
shares. Investors may also experience additional dilution as a result of the
exercise of outstanding stock options, or the issuance by the Company of
additional equity securities. See "Dilution."
 
ABSENCE OF DIVIDENDS
 
    The Company has not declared or paid any cash dividends on its Common Stock
since its inception and does not anticipate declaring or paying any such cash
dividends in the foreseeable future. See "Dividend Policy."

                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the 2,000,000 shares of
Common Stock offered to the public hereby are estimated to be $14.5 million
($16.7 million if the Underwriters' over-allotment option is exercised in full),
assuming an initial public offering price of $8.00 per share, and after
deducting estimated underwriting discounts and commissions and estimated
offering expenses payable by the Company.
 
    The Company currently intends to use approximately $5.5 million of such
proceeds to fund improvements to existing PhotoLink applications and the
development of new technological initiatives, primarily focused on additional
PhotoLink applications, including the hiring of additional technical personnel
to support such initiatives. An additional $1.5 million of the net proceeds is
intended to be used to upgrade its technical and production equipment over the
next two years. Further, the Company plans to use approximately $2.0 million of
the net proceeds to expand its sales and marketing capabilities by hiring
additional marketing personnel, and to support market development of new
PhotoLink applications. Finally, an estimated $1.0 million will be reserved to
strengthen SurModics' patent protection in additional worldwide markets and to
seek patent protection for new technology.
 
    The balance of the net proceeds will be used for working capital and general
corporate purposes. A portion of the net proceeds may also be used to acquire
technologies or products that complement the Company's current business. The
Company does not currently have any agreements, arrangements or understandings,
and is not involved in any negotiations, with respect to any such acquisitions,
and no portion of the net proceeds has been allocated for any specific
acquisition.
 
    Pending their use, the net proceeds will be invested in investment grade,
interest-bearing securities.
 
                                DIVIDEND POLICY
 
    The Company has not declared or paid cash dividends on its Common Stock
since its inception. The Company currently intends to retain any earnings for
use in the operation and expansion of its business and therefore does not
anticipate declaring or paying any cash dividends in the foreseeable future.

                                    DILUTION
 
    The pro forma net tangible book value of the Company's Common Stock at
September 30, 1997 was $4.8 million or $.98 per share. "Net tangible book value"
represents the tangible assets less total liabilities of the Company, and "pro
forma net tangible book value per share" was determined by dividing the net
tangible book value of the Company by the pro forma number of shares of Common
Stock outstanding on September 30, 1997. See "Capitalization." "Pro forma net
tangible book value dilution per share" represents the difference between the
initial public offering price per share and the pro forma net tangible book
value per share after this offering. Without taking into account any changes in
the Company's pro forma net tangible book value per share after September 30,
1997, other than to give effect to the sale of the 2,000,000 shares offered
hereby at an assumed initial offering price of $8.00 per share (net of
underwriting discounts and commissions and estimated offering expenses), the pro
forma net tangible book value of the Company at September 30, 1997 would have
been $19.2 million or $2.79 per share. This represents an immediate increase in
pro forma net tangible book value to the existing stockholders of $1.81 per
share and an immediate pro forma net tangible book value dilution to purchasers
of the shares of $5.21 per share, as illustrated by the following table:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
    SurModics, Inc. was formed in 1979 to conduct biomedical research for
government agencies and private industry. Historically, the Company relied
heavily on revenues from research grants from U.S. government agencies to fund
its operations. Since 1990, SurModics has focused its efforts on commercializing
its technologies.
 
    As indicated in the table below, the Company's revenues come from four
primary sources: fees from licensing its patented technology to customers;
royalties received from licensees; the sale of photo-reactive chemical compounds
to licensees and stabilization products to the diagnostics industry; and
research and development fees generated on projects for commercial customers and
pursuant to government grants. The Company expects that revenue generated from
government grants will continue to decline slightly as an absolute number but
more significantly as a percentage of total revenue in the future. The table
below reports each revenue category as a percentage of total revenues.

</TABLE>
 
    As indicated above, a significant portion of the Company's revenues are
derived from license fees and royalties. Generally, the Company's license
agreements provide for a term of 15 years or the life of the Company's patents
covering the licensed applications, whichever is longer, although the agreement
may be terminated earlier upon notice. These worldwide licenses can be either
exclusive or nonexclusive for a particular device, but over 75% of the Company's
licensed applications are nonexclusive. SurModics requires the payment of a
non-refundable license fee which has historically ranged from $25,000 to
$500,000 and quarterly royalties of 2% to 6% on sales of products incorporating
SurModics' technology. The amount of license fees and royalties are based on
whether the arrangement is exclusive or nonexclusive and the perceived value of
the PhotoLink application to the device. Certain nonrefundable license and
research and development fees are recoverable by the licensees as offsets
against a percentage of future earned royalties.
 
    The Company has attempted to diversify its revenue base by entering into
license agreements with many companies covering multiple product applications.
SurModics currently has license agreements with 32 companies covering 106
applications, of which 58 are generating royalty revenues for the Company. Most
of SurModics' agreements provide for the quarterly payment of the greater of a
minimum royalty or an "earned" royalty based on actual product sales. Many of
the licensed products incorporating SurModics' technology are still in the early
phase of their development, and the Company will not receive earned royalties on
these products until the licensees receive the necessary regulatory approvals
and commercialize these products, if at all. SurModics anticipates that the
Company's royalty revenues will continue to grow in the future as its licensees
succeed in bringing their licensed products to market.
 
    With the exception of the most recently completed fiscal year, the Company
has reported annual losses since inception. During fiscal 1997, the Company
recorded operating income of $37,000 and net income of $236,000. The Company's
accumulated deficit was $8.2 million as of September 30, 1997.
 
                                       16
<PAGE>
    Historically, most of the Company's expenses were incurred in connection
with its research and development activities. As additional products
incorporating the PhotoLink technology are commercialized by the manufacturers
of such products and consequently generate earned royalties for the Company,
management anticipates that the Company will be able to leverage its expense
base into increased profitability. The Company's licensing strategy should allow
it to grow its revenue without corresponding expense growth. However, as stated
in "Use of Proceeds," the Company does intend to further invest in sales,
marketing and technical resources in order to further penetrate its target
markets and to develop additional PhotoLink applications.
 
RESULTS OF OPERATIONS
 
    YEARS ENDED SEPTEMBER 30, 1997 AND 1996
 
    REVENUES.  The Company's revenues were $7.6 million for fiscal 1997, an
increase of $1.4 million, or 22.6%, over fiscal 1996. Between years, royalty
revenue increased 24.5%, product sales increased 31.6% and license fees
increased 41.1%. Research and development revenue increased 8.3%, with a 41.0%
increase in customer-funded research and development revenue, partially offset
by a 5.0% decrease in government-sponsored research and development revenue. In
general, these increases were due to greater customer development activity and
increased market penetration of products incorporating SurModics' technology.
 
    PRODUCT COSTS.  The Company's product costs were $1.4 million in fiscal
1997, an increase of $217,000, or 17.9%, compared to fiscal 1996. Product
margins increased to 33.7% in fiscal 1997 from 26.0% in fiscal 1996, primarily
due to manufacturing efficiencies achieved in producing reagent chemicals.
 
    RESEARCH AND DEVELOPMENT EXPENSE.  Research and development expense was $3.6
million in fiscal 1997, an increase of $280,000, or 8.5%, over fiscal 1996. The
change was primarily due to increased patent-related costs, additional research
studies at external laboratories and additional technical personnel.
 
    SALES AND MARKETING EXPENSE.  Sales and marketing expense was $1.1 million
in fiscal 1997, an increase of $186,000, or 20.5%, over fiscal 1996. This
increase was primarily due to additional marketing personnel and increased
customer activities, which resulted in more travel and promotional spending.
 
    GENERAL AND ADMINISTRATIVE EXPENSE.  General and administrative expense was
$1.4 million in fiscal 1997, an increase of $263,000, or 22.8%, compared to
fiscal 1996. The increase was primarily due to incentive compensation.
 
    OTHER INCOME (EXPENSE), NET.  The Company's net other income was $198,000 in
fiscal 1997, a decrease of $23,000 or 10.2% from fiscal 1996. This decrease was
due primarily to a reduced level of interest income from investments.
 
    YEARS ENDED SEPTEMBER 30, 1996 AND 1995
 
    REVENUES.  The Company's revenues were $6.2 million for fiscal 1996, an
increase of $227,000, or 3.8%, over fiscal 1995. Due to an overall increase in
customer activity, royalty revenue increased 12.4%, product sales increased
14.8% and research and development revenue increased 14.5%, which was comprised
of a 28.9% increase in customer-funded research and development revenue and a
9.6% increase in government-sponsored research and development revenue. License
fees declined $475,000, or 55.4%, to $383,000 in fiscal 1996 due to the timing
of finalizing new license arrangements. Fiscal 1995 included large fees
associated with two license agreements.
 
    PRODUCT COSTS.  The Company's product costs were $1.2 million for fiscal
1996, a decrease of $43,000, or 3.4%, compared to fiscal 1995. Product margins
increased to 26.0% in fiscal 1996 from 12.0% in fiscal 1995. This improvement
was primarily due to manufacturing efficiencies achieved in producing reagent
chemicals.

<PAGE>
    RESEARCH AND DEVELOPMENT EXPENSE.  Research and development expense was $3.3
million for fiscal 1996, an increase of $351,000, or 11.8%, over fiscal 1995.
The increase was primarily due to additional compensation-related expense and
research studies at external laboratories, offset by lower patent-related costs.
 
    SALES AND MARKETING EXPENSE.  Sales and marketing expense was $912,000 for
fiscal 1996, a decrease of $149,000, or 14.0%, compared to fiscal 1995. This
decrease was primarily attributable to lower compensation costs due to personnel
turnover and lower legal fees associated with the review of new license
agreements.
 
    GENERAL AND ADMINISTRATIVE EXPENSE.  General and administrative expense was
$1.2 million for fiscal 1996, an increase of $29,000, or 2.6%, over fiscal 1995.
The increase was primarily due to higher compensation costs offset by slightly
lower general legal costs.
 
    OTHER INCOME (EXPENSE), NET.  The Company's net other income was $221,000
for fiscal 1996, an increase of $88,000, or 66.2%, compared to fiscal 1995. The
primary reason for the increase was the improved performance of the Company's
investment portfolio. Performance of the Company's investment portfolio in
fiscal 1996 included losses of $55,000 on certain investments compared to losses
of $218,000 on these same investments in fiscal 1995. The Company completely
liquidated these investments in the second quarter of fiscal 1996.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
    See Notes 2 and 4 of Notes to Financial Statements for a discussion of
Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation," SFAS No. 128, "Earnings Per Share," SFAS No. 130,
"Reporting Comprehensive Income" and SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information."
 
NET OPERATING LOSS CARRYFORWARDS
 
    In accordance with Section 382 of the Internal Revenue Code of 1986, as
amended, a change in equity ownership of the Company of greater than 50% within
a three-year period results in an annual limitation on the Company's ability to
utilize its net operating loss ("NOL") carryforwards which accrued during the
tax periods prior to the change in ownership. As of September 30, 1997, the
Company had an NOL carryforward of approximately $6.4 million, which expires in
varying amounts through 2011. The sale of the shares of Common Stock in this
offering will not directly result in such limitation; however, the NOL
carryforwards may become subject to such a limitation due to subsequent changes
in the equity ownership of the Company.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    As of September 30, 1997, the Company had working capital of approximately
$2.1 million. Historically, the Company has primarily funded its operations
through government research grants and equity offerings, the most recent of
which occurred in the third quarter of fiscal 1994. For the last three fiscal
years, the Company has generated positive cash flow from operations.
 
    As of September 30, 1997, the Company had cash, cash equivalents and
investments totaling approximately $3.8 million. The Company's funds are
currently invested in short-term money market funds and investment grade,
interest-bearing securities with maturity dates of less than two years. As of
September 30, 1997, the Company had no debt, nor did it have any credit
agreements. The Company believes that its existing capital resources, including
the net proceeds from this offering, will be adequate to fund the Company's
operations into the foreseeable future.

                                    BUSINESS
 
GENERAL
 
    SurModics is a leading provider of surface modification solutions to the
medical device industry. The Company's primary focus is the commercialization of
its patented PhotoLink process through third-party licensing arrangements.
PhotoLink is a versatile, easily applied, light-activated coating technology
that modifies medical device surfaces by creating covalent bonds between those
surfaces and a variety of chemical agents. Through the PhotoLink process, these
chemical agents can impart many performance-enhancing characteristics, such as
lubricity, hemocompatibility, infection resistance and drug delivery, onto the
surface of a medical device without materially changing the dimensions or
physical properties of the device. The Company believes that medical device
manufacturers who utilize the Company's technology are able to significantly
improve the performance of their products and, in many cases, differentiate
their products in a highly competitive marketplace.
 
    The Company focuses on providing high value-added surface modification
solutions to a variety of medical device markets and product categories.
Examples of products in the market or under development that incorporate the
PhotoLink technology include interventional cardiology catheters, vascular
stents, interventional neurology catheters, guide wires and shunts, cardiac
rhythm management devices, and urological and gynecological devices. The surface
properties created by the PhotoLink technology have greatly reduced treatment
times in catheter-based vascular procedures and have shown the potential to
enhance the long-term performance of implantable devices by improving infection
resistance and promoting host cell attachment, growth and subsequent tissue
integration. The Company believes further opportunities exist to commercialize
its PhotoLink technology for other market applications, such as biomolecule
immobilization for use in the emerging field of DNA-based diagnostics.
 
    The Company has commercialized its PhotoLink technology through licensing
arrangements with medical device manufacturers which apply the PhotoLink
coatings to their own products. The Company believes this approach allows it to
focus its resources on further development of its technology and expansion of
its licensing activities, while leveraging the established manufacturing, sales
and marketing capabilities of its licensees. Revenues from these arrangements
include initial license fees, minimum royalties and earned royalties based on a
percentage of licensees' product sales. The Company currently has license
agreements with 32 companies covering 106 different applications, of which 58
are generating royalty revenues for the Company. In addition to licensing its
PhotoLink technology, the Company also licenses certain diagnostic technology to
Abbott Laboratories for use with rapid point-of-care diagnostic tests, such as
pregnancy and strep tests. The Company also manufactures and sells the chemical
reagents used in the PhotoLink process and stabilization products used to extend
the shelf-life of immunoassay diagnostic tests.
 
MARKETS AND NEED FOR SURFACE MODIFICATION
 
    Recent trends in healthcare toward improved patient outcomes and reduced
total costs have resulted in intense competition for the development of medical
devices that demonstrate superior product performance, reduced procedure times,
improved outcomes and overall cost effectiveness. In the highly competitive
medical device industry, many medical device manufacturers may offer similar
competing products for a single medical application. As a result, product
differentiation is critical to marketing success, and medical device
manufacturers are continually seeking new methods of distinguishing their
products from those of their competitors.
 
    Medical device manufacturers have attempted to address these competitive
pressures by developing innovative medical devices manufactured from a wide
variety of synthetic materials, including many new, expensive and exotic
materials. In an effort to further differentiate their products through improved
product performance, a growing number of medical device manufacturers are
turning to the emerging field of surface modification technology. Surface
modification technology enables device manufacturers to
 
                                       19
<PAGE>
provide medical devices with desired surface characteristics including improved
lubricity, hemocompatibility and infection resistance, as well as the ability to
deliver drugs and promote cell growth and tissue integration.
 
    Although it is an emerging field, surface modification technology has been
used to improve medical devices in many different industry segments. The table
below identifies several of these market segments and the surface properties the
Company believes are desired by each segment.

</TABLE>
 
    In addition to the above-identified market segments, the Company believes
that one of the next areas of growth for surface modification technology will be
the diagnostic test market. Diagnostic tests utilizing biomolecules, such as
DNA, can be used to screen for new drugs, to sequence unknown portions of the
human genome, or to search for signs of viruses. The Company believes
manufacturers of these diagnostic tests may benefit from surface modification
technology to provide biomolecule immobilization and wettability properties.
 
THE PHOTOLINK SOLUTION
 
    PhotoLink is a versatile, easily applied, light-activated coating technology
that modifies medical device surfaces by creating covalent bonds between those
surfaces and a variety of chemical agents. The PhotoLink process can impart many
performance-enhancing characteristics, such as lubricity, hemocompatibility,
infection resistance and drug delivery, onto the surface of a wide variety of
medical devices without significantly changing the dimensions or physical
properties of the device.
 
                                       20
<PAGE>
    The PhotoLink solution to surface modification involves the utilization of
proprietary, light sensitive (photochemical) reagents. These reagents can
consist of advanced polymers or active biomolecules having desired surface
characteristics and an attached light-reactive chemical compound (photogroup).
As illustrated in the following diagram, when the reagent is exposed to a direct
light source, typically ultraviolet, a photochemical reaction creates a covalent
bond between the photogroup and the surface of the medical device, thereby
imparting the desired property to the surface. A covalent bond is a very strong
chemical bond which results from the sharing of electrons between carbon
molecules of the substrate and the applied coating.
 
    [illustration of the PhotoLink coating process in which a polymer attached
to a photogroup is bonded to a surface when exposed to ultraviolet light]
 
    SurModics' proprietary PhotoLink reagents work on most polymer-based (E.G.,
plastic) substrates, biological substrates (latex rubber, cellulose, tissue and
natural fibers), and metal and glass substrates. Metal and glass substrates
generally require pretreating with polymers to make a carbon-molecule available
for bonding prior to the application of the PhotoLink reagents. The reagents are
easily applied to a clean material surface by dipping, spraying, roll coating,
ink jetting or brushing. SurModics continues to develop proprietary
photochemical reagents providing new product features while expanding the number
and type of substrates on which the reagents can be applied.
 
    ADVANTAGES
 
    The Company believes that its proprietary PhotoLink process provides its
licensees with a number of benefits.
 
    - FLEXIBILITY. PhotoLink coatings can be applied to many different kinds of
      surfaces and can immobilize a variety of chemical, pharmaceutical and
      biological agents, which allows licensees to be innovative in the design
      of their products without significantly changing their dimensions or
      physical properties.
 
    - VARIETY OF SURFACE PROPERTIES. The PhotoLink process can be tailored to
      provide SurModics' licensees with the ability to improve the performance
      of their devices by choosing the specific coating properties desired for
      particular applications. The PhotoLink technology also provides the
      medical device manufacturer with the ability to combine multiple
      surface-enhancing characteristics on the same device.
 
    - EASE OF USE. The PhotoLink coating process is a relatively simple process
      that does not require expensive special equipment or the use of hazardous
      materials and does not subject the coated products to harsh chemical,
      pressure or temperature conditions. Further, PhotoLink coatings are
      compatible with all the generally accepted sterilization processes, so the
      surface attributes are not lost when the medical device is sterilized
      prior to usage.
 
    SURFACE PROPERTIES
 
    SurModics' PhotoLink process has been used by manufacturers of pacemaker
leads, drug infusion catheters, laser and balloon angioplasty catheters, urinary
drainage catheters, vascular closure devices, wound drains, guide wires,
angiography catheters, ureteral stents and hydrocephalic shunts, among other
devices. The PhotoLink process can be used to provide medical device
manufacturers with the following surface properties to improve product
performance:
 
    - LUBRICITY. Low friction or lubricious coatings reduce the force and time
      required for insertion, navigation and removal of devices in vascular,
      neurological and urogenital applications. Lubricity also reduces tissue
      irritation and damage caused by products such as catheters, guide wires
      and endoscopy devices. Based on Company and licensee testing, when
      compared to uncoated surfaces, the PhotoLink process has reduced the
      friction on surfaces by as much as 85% to 95%, depending on the substrate
      being coated.
 
                                       21
<PAGE>
    - HEMOCOMPATIBILITY. Hemocompatible coatings help reduce adverse reactions
      that may be created when a device is inserted into the body and comes in
      contact with blood. Heparin has been used for decades as an injectable
      drug to reduce blood clotting in patients. SurModics can immobilize
      heparin on the surface of blood-contacting medical devices thereby
      inhibiting blood clotting on the device surface, minimizing patient risk
      and enhancing the performance of the device. PhotoLink heparin coatings
      have been shown in Company and licensee testing to reduce blood clotting
      by greater than 90% compared to uncoated surfaces. SurModics has
      immobilized several other chemical agents in addition to heparin that have
      also demonstrated improved hemocompatibility.
 
    - INFECTION RESISTANCE. Antimicrobial coatings are advantageous for most
      implantable medical devices where risk of infection is a concern.
      PhotoLink technology can apply passive coatings which significantly reduce
      bacterial adhesion to the device or active coatings incorporating
      antimicrobial agents which kill bacteria around the device. Testing by the
      Company has demonstrated that the PhotoLink process reduces the adherence
      of microorganisms to biomaterial surfaces by 97% to over 99% depending on
      the base material of the device. In addition, when compared to uncoated
      products, the PhotoLink process has been shown to increase the uptake of
      antimicrobial agents applied to the device just prior to implantation and
      prolong the release of these agents.
 
    - DRUG DELIVERY. PhotoLink technology can be used to crosslink polymers and
      create reservoirs to entrap drugs on the surface of medical devices. These
      drugs can then be released from the surface on a controlled basis by
      tailoring the polymers, by adjusting the extent of crosslinking, or by
      using a barrier coating to control diffusion. For example, SurModics has
      developed a PhotoLink coating that would allow a coronary stent
      manufacturer to incorporate a drug onto the stent directed at reducing the
      incidence of restenosis (the re-narrowing of the artery).
 
    - WETTABILITY. PhotoLink hydrophilic coatings have been shown in tests by
      the Company and its licensees to accelerate liquid flow rates on normally
      hydrophobic (water repelling) materials by 75%. Rapid point-of-care
      diagnostic tests, such as home monitoring or physician monitoring of
      glucose levels in diabetics, are currently done by pricking a patient's
      finger and carefully placing a drop of blood onto a polymer strip which is
      then inserted into a blood glucose reader. The Company believes that the
      time it takes for the blood to flow up the strip to provide the patient
      with a readout can be dramatically reduced and the consistency can be
      greatly improved with PhotoLink technology.
 
    - CELL GROWTH, TISSUE INTEGRATION AND OTHER TISSUE ENGINEERING. Studies have
      shown that attachment of extracellular matrix proteins and peptides onto
      surfaces of implantable medical devices improves host cell attachment,
      growth and subsequent tissue integration. PhotoLink technology has been
      used to coat biomedical devices with photoreactive collagens and other
      proteins upon which cells normally grow within the body. Company studies
      have shown that biomedical devices (such as vascular grafts and ocular
      implants) coated with such proteins, have improved attachment, growth of
      cells and acceptance by surrounding tissues. In addition, the Company is
      also using its PhotoLink technology to produce three-dimensional scaffolds
      to promote bone regeneration.
 
    - BIOMOLECULE IMMOBILIZATION. During a DNA gene analysis, typically hundreds
      of different probes need to be placed in a pattern on a surface, called a
      DNA array. These arrays can be used by the pharmaceutical industry to
      screen for new drugs, by genome mappers to sequence unknown portions of
      the human genome, or by diagnostic companies to search a patient sample
      for disease-causing bacteria or viruses. However, DNA does not readily
      adhere to most surfaces that are important for DNA assays. The Company has
      demonstrated a versatile method for the immobilization of DNA on various
      surfaces.

STRATEGY
 
    The Company's goal is to be the leading provider of surface modification
solutions to companies in the medical device industry. To achieve this goal,
SurModics intends to implement the following key strategies:
 
    - FURTHER PENETRATE AND EXPAND ITS LICENSING BASE. The Company intends to
      continue to focus on commercializing its technology through
      application-by-application licensing agreements with medical device
      manufacturers. Under this strategy, SurModics intends to continue to
      license its PhotoLink technology to multiple licensees within the same
      market, thereby increasing SurModics' revenue potential.
 
    - FURTHER DEVELOP APPLICATIONS FOR THE PHOTOLINK TECHNOLOGY. The PhotoLink
      process is extremely flexible, which provides the Company with many
      potential useful applications in the medical device industry. The Company
      intends to devote research and development efforts to further enhance the
      lubricious, hemocompatible and infection resistant properties of its
      existing PhotoLink applications, and to further develop applications
      involving controlled drug delivery and release, DNA immobilization and
      cell growth and tissue integration.
 
    - EXPAND SALES AND MARKETING RESOURCES. Because of the technical nature of
      the Company's operations, SurModics' marketing strategy is to utilize a
      technically sophisticated direct sales force, which works closely with
      both the Company's and its customers' development staff. The Company
      intends to increase its direct sales resources to increase market
      awareness of the Company's technological capabilities and developments.
      The Company also intends to improve its market research capabilities to
      investigate new PhotoLink applications.
 
    - SEEK JOINT DEVELOPMENT PROGRAMS. The Company intends to aggressively
      pursue opportunities with medical device companies to expand its
      technology, internal expertise and revenue base while reducing
      developmental risks by sharing them with others. SurModics is engaged in
      several such joint development programs, including one regarding
      controlled drug delivery and release and another involving DNA
      immobilization.
 
    - EXPAND THE COMPANY'S PRODUCT PORTFOLIO. SurModics believes that it can
      utilize its know-how and expertise in surface modified devices,
      photoreactive crosslinking and bonding, and reagent chemistry to develop
      additional proprietary products that SurModics can directly sell, rather
      than license, to the medical marketplace. The Company may acquire
      technologies and products which are closely related to or utilize its
      technology, thereby allowing the Company to leverage its existing presence
      in the medical marketplace.
 
CURRENT LICENSING ARRANGEMENTS
 
    The Company has commercialized its PhotoLink technology through licensing
arrangements with medical device manufacturers who apply the PhotoLink coatings
to their own products. The Company believes this approach allows it to focus its
resources on further developing its technology and expanding its licensing
activities, while leveraging the established manufacturing, sales and marketing
capabilities of its licensees for the marketing of the specific medical device
utilizing the PhotoLink technology. The Company believes its licensees generally
find the licensing arrangement to be beneficial for them because it is designed
to allow manufacturers to incorporate the PhotoLink process into their own
manufacturing processes without the need to send product outside their facility,
resulting in tighter quality control and reduced investment in work-in-process
inventory.
 
                                       23

    SurModics currently has license agreements with 32 companies covering 106
applications. The following table identifies selected licensees of SurModics'
PhotoLink technology, some of the medical devices that incorporate SurModics'
technology and the surface characteristics sought by the licensee.

- ------------------------
 
(1) The devices marked with an asterisk are currently generating earned
    royalties for SurModics based on the respective licensee's sale of the
    medical device incorporating SurModics' technology. The devices not marked
    with an asterisk are in the development stage and may never generate earned
    royalties for the Company.
 
    The licensing process begins with the medical device manufacturer specifying
the surface characteristics it desires. Because each surface is unique, the
Company routinely conducts a feasibility study at no charge to the customer to
qualify each new potential product application by SurModics. Once the
feasibility has been proven, the customer typically funds further development by
SurModics to optimize the coating formulation to meet the customer's technical
and financial needs. A license agreement is then executed and SurModics'
technical personnel assist the licensee in incorporating the PhotoLink process
into its manufacturing facility. SurModics provides ongoing assistance in
reagent handling, capital equipment recommendations, process control and trouble
shooting. The Company also manufactures and sells the chemical reagents used in
the PhotoLink process, thus creating another source of revenue.
 
    The term of a license agreement is generally for a period of 15 years or the
life of SurModics' patents covering the licensed application, whichever is
longer, although an agreement may be terminated for any reason upon prior
written notice, typically required at least 90 days before termination. The
worldwide license can be either exclusive or nonexclusive for a particular
medical device, but over 75% of the Company's licensed applications are
nonexclusive. SurModics requires the payment of a non-refundable
 
                                       24
<PAGE>
license fee which has historically ranged from $25,000 to $500,000 and quarterly
"earned" royalties of 2% to 6% on the sales of products incorporating SurModics'
technology. The amount of license fees and royalties are based on whether the
arrangement is exclusive or nonexclusive and the perceived value of the
PhotoLink application to the device. Certain nonrefundable license and research
and development fees are recoverable by the licensees as offsets against a
percentage of future earned royalties. Most of SurModics' agreements incorporate
a minimum royalty to be paid by the licensee while the medical devices are
developed, tested and commercialized. In certain cases, payment of these minimum
royalties may not commence until several months after the execution of an
agreement for a particular application.
 
OTHER PRODUCTS
 
    STABILIZATION PRODUCTS
 
    Although the primary focus of the Company is the development and marketing
of its PhotoLink technology, the Company also develops and markets stabilization
products for use by manufacturers of immunoassay diagnostic tests. SurModics'
StabilCoat and StabilZyme Stabilizers are designed to maintain the activity of
biological components of the immunoassays, resulting in a longer shelf-life.
These products offer SurModics' customers the benefit of product differentiation
and improvement while providing the ultimate end users the benefit of a faster
test with fewer steps and fewer errors. In fiscal 1997, SurModics generated $1.7
million of revenue from its stabilization products.
 
    DIAGNOSTIC FORMATS
 
    The Company also licenses a format for IN VITRO diagnostic tests developed
during the early years of the Company. This format has found broad application
in the expanding area of rapid point-of-care diagnostic testing, such as
pregnancy and strep tests, and generated $1.5 million of royalty revenue for the
Company in fiscal 1997 pursuant to the license agreement with Abbott. Although
this revenue is expected to grow in the future with the increased sales of
licensed products, limited additional SurModics-funded research and development
is being undertaken in this area.
 
    INDUSTRIAL APPLICATIONS
 
    While it is not the Company's primary focus, the Company occasionally
pursues industrial applications for its PhotoLink technology. The Company only
pursues those applications that are perceived to be high-value applications in a
market that is not considered to be price sensitive. To date, revenue associated
with industrial applications has been immaterial and is not expected to be
significant in the foreseeable future.
 
RESEARCH AND DEVELOPMENT
 
    SurModics' research and development department supports the marketing staff
in performing feasibility studies, providing technical assistance to potential
licensees, optimizing the coating methodologies for specific licensee
applications, assisting in training licensees and integrating the Company's
technology and know-how into licensee manufacturing processes. In addition, the
research and development department works to enhance and expand the PhotoLink
technology through the development of new reagents and new applications.
 
    As medical devices become more sophisticated and complex, the Company
believes the requirements for optimized surface properties will grow. The
Company intends to continue its development efforts to allow its PhotoLink
technology to provide additional optimized surface properties to meet these
needs. The Company's technical strategy is to target selected coating
characteristics for further development prior to licensing, in order to
facilitate and shorten the license cycle. The Company has begun to perform
research into applications for future products both on its own and in
conjunction with some of its licensees. Some of the identified research and
development opportunities include coatings designed to improve the
characteristics of long-term implants, site-specific drug release, orthopedic
repair materials and devices, long-term blood compatibility and DNA
immobilization methods. In addition to expanding the number of medical
applications that may use PhotoLink technology, the Company intends to broaden
the spectrum of
 
                                       25
<PAGE>
surfaces on which reagents can be applied, improve the coating process for
metals and glass, develop a process for coating the interior diameter of medical
devices, expand the portfolio of PhotoLink reagents, and develop additional
proprietary products in which PhotoLink reagents serve as the end product.
 
    The technical staff of the Company consists of 46 scientists, including
seven with Ph.D. degrees, four with Masters degrees and 31 with Bachelor
degrees, with expertise in chemistry, biomedical engineering, biology,
microbiology, cell biology and biochemistry. The technical staff is organized
into five areas of specialization: hydrophilicity, microbiology,
hemocompatibility, biochemistry and tissue engineering. In addition, a chemistry
group supports the synthesis of new reagents needed by the other five groups.
SurModics intends to use a portion of the net proceeds from this offering to
hire additional technical personnel.
 
    In fiscal 1996 and 1997, the Company's research and development expenses
were $3.3 million and $3.6 million, respectively. The Company's research and
development efforts are often funded by commercial licensees and government
agencies. Such research and development revenues during these periods were $1.8
million and $2.0 million, respectively.
 
    Since its founding, the Company has actively participated in the federal
government's Small Business Innovative Research ("SBIR") program to fund
development efforts. Since 1979, 136 research contracts resulting in revenues of
over $23 million have been awarded to SurModics, primarily under the SBIR
program. Grant proposals are generally directed toward the commercial strategies
of the Company. The Company retains commercial rights to discoveries and
technologies resulting from the research and development efforts funded by these
grants. Where possible, licensees' products or substrates are used when
performing research under the grant; thus the results are often directly
applicable to SurModics' licensees. Grant funding has also allowed SurModics to
maintain a larger and more technologically diverse employee base than would
otherwise be possible.
 
PATENTS AND PROPRIETARY RIGHTS
 
    The Company believes that it has protected its PhotoLink technology through
a series of patents covering a variety of coating methods, reagents and
formulations, as well as particular medical device applications, based on or
employing the Company's proprietary photoreactive chemistry. The series of
patents related to the PhotoLink technology includes 12 issued and three allowed
U.S. patents and seven pending U.S. patent applications, with similar protection
being sought in 28 pending and seven issued patents in various foreign
countries. The Company generally files international patent applications in
parallel with most U.S. applications. The Company generally files in Australia,
Canada, Europe, Japan and Mexico. In addition to the series of patents regarding
PhotoLink technology, SurModics has three issued U.S. patents, with similar
protection being sought in nine pending and 13 issued patents in various foreign
countries, related to its diagnostic technology. There can be no assurance that
any of the pending patent applications will be approved.
 
    The commercial success of the Company will depend, in part, on its ability
to protect its existing patents, to obtain patent protection for newly developed
technology, and to avoid infringing patents issued to others, of which there can
be no assurance. Furthermore, there can be no assurance that others will not
independently develop similar products, duplicate any of the Company's products
or, if patents are issued to the Company, design around, circumvent or challenge
the Company's patents. There can also be no assurance that the Company's trade
secrets or confidentiality agreements with potential licensees or other parties
will provide meaningful protection for the Company's unpatented proprietary
information. Litigation, which could result in substantial costs to the Company
and substantial diversion of the efforts of its management and technical
personnel, may be necessary to protect the Company's intellectual property
rights or to determine the scope and validity of third-party proprietary rights.
 
    The Company also relies heavily upon trade secrets and unpatented
proprietary technology. The Company seeks to maintain the confidentiality of
such information by requiring employees, consultants and other parties to sign
confidentiality agreements and by limiting access by parties outside the Company
 
                                       26
<PAGE>
to such information. There can be no assurance, however, that these measures
will prevent the unauthorized disclosure or use of this information or that
others will not be able to independently develop such information. Additionally,
there can be no assurance that any agreements regarding confidentiality and
non-disclosure will not be breached, or, in the event of any breach, that
adequate remedies would be available to the Company.
 
MARKETING AND SALES
 
    The Company markets its PhotoLink process throughout the world using a
direct sales force consisting of four licensing managers who focus on specific
markets such as cardiology devices, diagnostic products and urology products.
This specialization fosters an in-depth knowledge of the issues faced by
SurModics' licensees within these markets such as technology changes,
biomaterial changes and the regulatory environment.
 
    Because the sales cycle can take several months from feasibility
demonstration to the execution of a license agreement, the Company focuses its
sales efforts on potential licensees with established market positions rather
than those with only development stage products which may never come to market.
Generally, the PhotoLink technology is licensed to medical device manufacturers
for use on specific products. This strategy enables the Company to license the
PhotoLink technology to multiple licensees in the same market. SurModics also
targets selling new applications to existing licensees. The Company believes the
sales cycle is much faster in these situations because the licensee is already
familiar with the technology and the general terms of the license have already
been negotiated. The Company intends to use a portion of the net proceeds from
this offering to increase the size of its direct sales staff and to expand its
market research capabilities to investigate new PhotoLink applications.
 
    As part of its marketing strategy, the Company publishes technical
literature on each surface capability of the PhotoLink technology (I.E.,
lubricity, hemocompatibility, etc.). In addition, the Company participates at
major trade shows and technical meetings, advertises in trade journals and
through its website, and conducts direct mailings to appropriate target markets.
 
    The Company also offers ongoing customer service and technical support
throughout a licensee's relationship with SurModics. As part of this service and
support, SurModics performs initial coating feasibility studies on the
licensee's device at no charge, optimizes the licensee's application before
final release, educates and trains the licensee on the technology to
successfully transfer the process to its manufacturing facility, and assists the
licensee with FDA submissions for coated product approval.
 
COMPETITION
 
    Competition in the medical device industry has resulted in an increase in
competition in the surface modification market. The Company's PhotoLink
technology competes with technologies developed by Biocompatibles International
plc, Carmeda (a division of Norsk Hydro, Inc.), Specialty Coatings Systems,
Spire Corporation and STS Biopolymers Inc., among others. In addition, many
medical device manufacturers have developed or are engaged in efforts to develop
surface modification technologies for use on their own products. Most
competitors marketing surface modification to the outside marketplace are
divisions of organizations with businesses in addition to surface modification.
Overall, the Company believes the worldwide market is very fragmented with no
competitor marketing to third parties having more than a 10% market share. Many
of the Company's existing and potential competitors (including medical device
manufacturers pursuing coating solutions through their own research and
development efforts) have substantially greater financial, technical and
marketing resources than the Company.
 
    SurModics attempts to differentiate itself from its competition by providing
what it believes is a high value-added solution to surface modification. The
Company believes that the primary factors customers consider in choosing a
particular surface modification technology are performance, ease of
manufacturing, ability to produce multiple properties from a single process,
compliance with manufacturing regulations, customer service and pricing. The
Company believes that its PhotoLink process competes favorably with respect to
these factors, enabling it to charge a premium price. The Company believes that
the cost and
 
                                       27
<PAGE>
time required to obtain the necessary regulatory approvals significantly reduces
the likelihood of a manufacturer changing the coating process it uses once a
device has been approved for marketing.
 
    Because a significant portion of the Company's revenue is dependent on the
receipt of royalties based on sales of medical devices incorporating PhotoLink
coatings, the Company is also affected by competition within the markets for
such devices. The Company believes that the intense competition within the
medical device markets creates opportunities for the Company's coating
technology as medical device manufacturers seek to differentiate their products
through new enhancements or to remain competitive with enhancements offered by
other manufacturers. Because the Company seeks to license its technology on a
non-exclusive basis, the Company may further benefit from competition within the
medical device markets by offering its PhotoLink technology to multiple
competing manufacturers of a device. However, competition in the medical device
markets could also have an adverse affect on the Company. While the Company
seeks to license its products to established manufacturers, in certain cases the
Company's licensees may compete directly with larger, dominant manufacturers
with extensive product lines and greater sales, marketing and distribution
capabilities. The Company also is unable to control other factors that may
impact commercialization of PhotoLink-coated devices, such as the marketing and
sales efforts of its licensees or competitive pricing pressures within the
particular device market. There can be no assurance that products coated with
the PhotoLink technology will be successfully commercialized by the Company's
licensees or that such licensees will otherwise be able to effectively compete.
 
    The primary competition for SurModics' stabilization products is its
customers' internally developed formulations. The consolidation of the
diagnostic industry increases the availability of internally developed
stabilizers to the market. There are several direct competitors that have
recently emerged, of which Pierce Medical Products, Inc. and Medix, Inc. are the
two largest. The Company believes that quick market penetration is the best
strategy for addressing these threats. As in the coating market, the Company
also believes that once its stabilization products are accepted in an
FDA-approved diagnostic test, the likelihood of change is reduced because of the
cost and time required to qualify a new component. SurModics' marketing strategy
for its stabilization products is to develop a strong market presence by
offering superior product performance and technical service.
 
MANUFACTURING
 
    In accordance with its licensing strategy, the Company does not perform the
actual coating of its licensees' medical devices, nor does it manufacture any of
these devices. The Company has, however, adopted a strategy of developing and
manufacturing the reagents itself, allowing it to maintain the quality of the
reagents and their proprietary nature, while providing an additional source of
revenue. PhotoLink reagents are specialty photoreactive chemicals that are
prepared using a proprietary formula in small batch processes (as contrasted
with commodity chemicals prepared by large continuous methods). Generally, all
PhotoLink reagents share a similar production process: a water soluble polymer
is synthesized in a glass reactor; reactive photochemical groups are attached to
the polymer; the solution is purified and freeze-dried, thus removing the water
and creating a solid; and the PhotoLink reagents are packaged in standard
quantities in light- and moisture-proof packaging. The reagents are sold dry,
requiring the licensee, in most cases, to simply add water or a water and
isopropyl alcohol mix before application. The Company has developed proprietary
testing and quality assurance standards for manufacturing the reagents and does
not disclose the reagent formulas or manufacturing methods. Although licensees
may purchase the requisite chemical reagents from any source, all have elected
to purchase them from the Company.
 
                                       28
<PAGE>
    The Company also manufactures its stabilization products. These products are
a group of sterile-filtered liquids that generally share a three-step production
process. A standard recipe of chemicals is mixed in high purity water, these
liquids are sterile-filtered into specific container sizes under aseptic
conditions, and the resultant finished goods are packaged and labeled.
 
    The Company maintains multiple sources of supply for the key raw materials
used to manufacture reagents and stabilization products. The Company does,
however, purchase some raw materials from single sources, but it believes that
additional sources of supply are readily available.
 
    Although not required to follow Good Manufacturing Practice quality
procedures, SurModics does follow such procedures in part to respond to requests
of licensees to establish compliance with their criteria. The Company has not
yet sought ISO 9001 certification but may do so in the future.
 
GOVERNMENT REGULATION
 
    Although PhotoLink technology itself is not directly regulated by the FDA,
the medical devices incorporating this technology are subject to FDA regulation.
The burden of demonstrating safety and efficacy of such medical devices, the
ultimate criteria applied by the FDA, rests with the Company's licensees (the
medical device manufacturers). Medical products incorporating the PhotoLink
technology may generally be marketed only after 510(k) or PMA applications have
been submitted and approved by the FDA, which process can take anywhere from six
months for a 510(k) application and to two or three years for a PMA application.
These applications are prepared by the manufacturer and contain results of
extensive laboratory toxicity, mutagenicity and clinical evaluations on animals
and humans conducted by the manufacturer.
 
    The Company maintains confidential Device Master Files at the FDA regarding
the nature, chemical structure and biocompatibility of the PhotoLink reagents.
Although the Company's licensees do not have access to these files, the
licensees may, with the permission of the Company, reference these files in any
medical device submission to the FDA. This process allows the FDA to understand
in confidence the details of the PhotoLink technology without the Company having
to share this highly confidential information with its licensees.
 
    Recent U.S. legislation allows device manufacturers, prior to obtaining FDA
approval to market a medical device in the U.S., to manufacture such medical
device in the U.S. and export it for sale in international markets, which could
allow SurModics to realize earned royalties sooner. However, sales of medical
devices outside the U.S. are subject to international requirements that vary
from country to country. The time required to obtain approval for sale
internationally may be longer or shorter than that required by the FDA.
 
EMPLOYEES
 
    As of December 1, 1997, SurModics had 85 employees of whom 52 were engaged
in development or manufacturing positions, with the remainder in marketing,
quality or administrative positions. Of SurModics' employees, seven hold Ph.D.
degrees and nine hold Masters degrees. The Company is not a party to any
collective bargaining agreements and believes that its employee relations are
good.
 
    Management believes that the future success of the Company will depend in
part on its ability to attract and retain qualified technical, management and
marketing personnel. Such experienced personnel are in high demand, and the
Company must compete for their services with other firms which may be able to
offer more favorable benefits.
 
FACILITIES
 
    SurModics leases approximately 35,000 square feet of office/warehouse space
in Eden Prairie, Minnesota under a lease that expires at the end of 1999.
SurModics has an option to extend this lease
 
                                       29
<PAGE>
through the end of 2001. The lease commitment for fiscal 1998 is approximately
$210,000. Of the total leased space, approximately 15,000 square feet is office
space, 13,000 square feet is laboratory space and 7,000 square feet is
manufacturing space. Approximately 6,000 square feet of the manufacturing space
is a HEPA-filtered, highly controlled environment, but not certified as a "clean
room" under FDA standards. The Company believes that projected capacity of the
manufacturing area is adequate to service the needs of its licensees for the
foreseeable future.

STOCK OPTIONS
 
    On January 27, 1997, the Board of Directors and stockholders of the Company
adopted the 1997 Incentive Stock Option Plan (the "Plan") in order to provide
for the granting of stock purchase options to employees and officers of the
Company. The Plan permits the granting of incentive stock options meeting the
requirements of Section 422A of the Internal Revenue Code of 1986. The Company
has reserved 600,000 shares of its Common Stock for issuance upon exercise of
options granted under the Plan. As of the date of this Prospectus, the Company
has outstanding options to purchase an aggregate of 30,200 shares under the
Plan. The Company also has outstanding options, granted pursuant to the
Company's 1987 Incentive Stock Option Plan, which plan expired on January 18,
1997, to purchase an aggregate of 302,800 shares. In addition, the Company has
outstanding non-qualified options, granted outside of either of the foregoing
plans, to purchase an aggregate of 906,800 shares of Common Stock.
 
CERTAIN TRANSACTIONS
 
    In August 1997, the Company adopted a plan pursuant to which an employee of
the Company could borrow amounts from the Company to fund option exercises. Any
loan made pursuant to this plan is required to provide for: a five-year term,
subject to automatic acceleration to the earlier of three months after
termination of employment or six months after the shares purchased become
eligible for sale in the public market; interest payable annually at the prime
rate in effect at the time of the loan, paid annually; principal payable at
maturity; and a pledge of the shares of Common Stock acquired with the proceeds
of the loan as security. The Board has the authority to terminate this plan at
any time and will do so upon completion of this offering. Under the terms of
this loan program, (i) Walter H. Diers, Jr., Vice President of Corporate
Development for the Company, borrowed an aggregate of $80,000 on September 19,
1997, at an interest rate of 8.5%, to exercise an option to purchase an
aggregate of 20,000 shares of Common Stock at $4.00 per share and (ii) James C.
Powell, Vice President of Technical Operations for the Company, borrowed an
aggregate of $56,000 on September 19, 1997, at an interest rate of 8.5% to
exercise an option to purchase an aggregate of 14,000 shares of Common Stock at
$4.00 per share.

                          DESCRIPTION OF CAPITAL STOCK
 
    Upon completion of this offering, assuming approval by the stockholders of
the amendment to the Company's Restated Articles of Incorporation, as amended,
which is discussed below, the authorized capital stock of the Company will
consist of 20,000,000 shares of capital stock, $0.05 per share par value, of
which 15,000,000 shares are Common Stock and 5,000,000 shares are undesignated.
 
COMMON STOCK
 
    As of December 1, 1997, the Company had approximately 200 shareholders of
record holding 3,400,868 shares of issued and outstanding Common Stock,
including 84,000 shares issued pursuant to restricted stock agreements. The
holders of the Common Stock: (i) have equal ratable rights to dividends from
funds legally available therefor, when, as and if declared by the Board of
Directors of the Company; (ii) are entitled to share ratably in all the assets
of the Company available for distribution to holders of the Common Stock upon
liquidation, dissolution or winding up of the affairs of the Company; and (iii)
are entitled to one vote per share on all matters which stockholders may vote on
at all meetings of stockholders. All shares of Common Stock now outstanding are
fully paid and nonassessable and the shares of Common Stock to be issued upon
completion of this offering will be fully paid and nonassessable. There are no
redemption, sinking fund, conversion or preemptive rights with respect to the
shares of Common Stock.
 
    The holders of the Common Stock do not have cumulative voting rights.
Subject to the rights of any future series of preferred stock, the holders of
more than 50 percent of such outstanding shares voting for the election of
directors can elect all of the directors of the Company to be elected, if they
so choose. In such event, the holders of the remaining shares will not be able
to elect any of the Company's directors.
 
SERIES A CONVERTIBLE PREFERRED STOCK
 
    Upon the closing of this offering, the 376,828 shares of outstanding Series
A Convertible Preferred Stock, held of record by approximately 70 shareholders,
will be converted automatically into an aggregate of 1,507,312 shares of Common
Stock. The Board of Directors has approved an amendment to the Company's
Restated Articles of Incorporation, as amended, subject to stockholder approval
at their annual meeting in January 1998, to provide that, upon completion of
this offering and the concurrent automatic conversion of outstanding shares of
Series A Convertible Preferred Stock into Common Stock, the Board shall take the
necessary steps to cancel the class of and eliminate the shares authorized as
Series A Convertible Preferred Stock.
 
UNDESIGNATED STOCK
 
    Under governing Minnesota law and the Company's Restated Articles of
Incorporation, as amended, no action by the Company's stockholders is necessary,
and only action of the Board of Directors is required, to authorize the issuance
of any of the undesignated stock. The Board of Directors is empowered to
establish and to designate each class or series of the undesignated shares and
to set the terms of such shares (including terms with respect to redemption,
sinking fund, dividend, liquidation, preemptive, conversion and voting rights
and preferences). Accordingly, the Board of Directors, without stockholder
approval, may issue such undesignated shares in one or more series of preferred
stock having rights, preferences, privileges or restrictions, including voting
rights, that may be greater than the rights of holders of Common Stock.
 
    It is not possible to state the actual effect of the issuance of any shares
of preferred stock upon the rights of holders of the Common Stock until the
Board of Directors determines the specific rights of the holders of such
preferred stock. However, the effects might include, among other things,
restricting dividends on the Common Stock, diluting the voting power of the
Common Stock, impairing the liquidation rights of the Common Stock and delaying
or preventing a change in control of the Company
 
                                       36
<PAGE>
without further action by the stockholders. The Company has no present plans to
issue any shares of preferred stock.
 
MINNESOTA BUSINESS CORPORATION ACT
 
    Certain provisions of Minnesota law described below could have an
anti-takeover effect. These provisions are intended to provide management
flexibility and to enhance the likelihood of continuity and stability in the
composition of the Company's Board of Directors and in the policies formulated
by the Board and to discourage an unsolicited takeover of the Company, if the
Board determines that such a takeover is not in the best interests of the
Company and its stockholders. However, these provisions could have the effect of
discouraging certain attempts to acquire the Company which could deprive the
Company's stockholders of opportunities to sell their shares of Common Stock at
prices higher than prevailing market prices.
 
    Section 302A.671 of the Minnesota Statutes applies, with certain exceptions,
to any acquisition of voting stock of the Company (from a person other than the
Company, and other than in connection with certain mergers and exchanges to
which the Company is a party) resulting in the beneficial ownership of 20
percent or more of the voting stock then outstanding. Section 302A.671 requires
approval of any such acquisitions by a majority vote of the stockholders of the
Company prior to its consummation. In general, shares acquired in the absence of
such approval are denied voting rights and are redeemable at their then fair
market value by the Company within 30 days after the acquiring person has failed
to give a timely information statement to the Company or the date the
stockholders voted not to grant voting rights to the acquiring person's shares.
 
    Section 302A.673 of the Minnesota Statutes generally prohibits any business
combination by the Company, or any subsidiary of the Company, with any
stockholder which purchases 10 percent or more of the Company's voting shares
(an "interested stockholder") within four years following such interested
stockholder's share acquisition date, unless the business combination is
approved by a committee of all of the disinterested members of the Board of
Directors of the Company serving before the interested stockholder's share
acquisition date.
 
CERTAIN LIMITED LIABILITY AND INDEMNIFICATION PROVISIONS
 
    The Company's Restated Articles of Incorporation, as amended, limit the
personal liability of its directors. Specifically, directors of the Company will
not be personally liable to the Company or its stockholders for monetary damages
for any breach of their fiduciary duty as directors, except to the extent that
the elimination or limitation of liability is in contravention of the MBCA, as
amended. This provision will generally not limit liability under state or
federal securities law.
 
    Section 302A.521 of the MBCA provides that a Minnesota business corporation
shall 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.
 
    Section 5.1 of the Company's Bylaws provides that each director, officer and
employee of the Company shall be indemnified by the Company in accordance with,
and to the fullest extent permissible by, applicable law.
 
    The Company is in the process of obtaining an insurance policy covering
director and officer liability.
 
                                       37
<PAGE>
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or controlling persons of the Company
pursuant to the foregoing provisions, the Company has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.
 
TRANSFER AGENT AND REGISTRAR
 
    The Transfer Agent and Registrar with respect to the Company's Common Stock
will be Firstar Trust Company.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this offering, there has been no public market for the Common
Stock. Future sales of substantial amounts of Common Stock in the open market
may adversely affect the market price of the Common Stock offered hereby and the
ability of the Company to raise equity capital in the future.
 
    Upon consummation of the offering, the Company will have outstanding an
aggregate of 6,908,180 shares of Common Stock (assuming no exercise of the
Underwriters' over-allotment option). Of the aggregate number of outstanding
shares of Common Stock, the 2,000,000 shares of Common Stock sold in this
offering will be freely tradable without restriction or further registration
under the Securities Act, unless purchased by an "affiliate" of the Company, as
that term is defined by Rule 144 promulgated under the Securities Act (an
"Affiliate"), whose sales would be subject to certain volume limitations and
other restrictions described below. The remaining 4,908,180 shares of Common
Stock originally issued and sold by the Company in private transactions in
reliance upon exemptions from the Securities Act held by stockholders upon the
consummation of this offering will be "restricted securities" as that term is
defined in Rule 144 under the Securities Act, and may be sold in the public
market only if registered or if they qualify for an exemption from registration
under Rule 144, 144(k) or 701 or otherwise.
 
    All officers and directors and certain stockholders of the Company, owning
an aggregate of 3,636,648 shares, have entered into "lock-up" agreements,
agreeing not to, directly or indirectly, sell, assign, transfer, encumber, offer
to sell, grant any option for the sale of, or otherwise dispose of, any shares
of Common Stock without the consent of the Representative for a period of 180
days after the date of this Prospectus. The Representative may waive these
restrictions at any time in its discretion. Taking such restrictions into
account, in addition to the 2,000,000 shares of Common Stock offered hereby, (i)
approximately 1,162,716 shares will be eligible for immediate sale on the date
of this Prospectus in accordance with Rule 144; (ii) approximately 17,428
additional shares will become eligible for sale in the public market beginning
90 days after the date of this Prospectus in accordance with Rule 144; and (iii)
approximately 3,599,668 additional shares will be eligible for sale beginning
180 days after the date of this Prospectus upon the expiration of the lock-up
agreements, subject, in the case of Affiliates, to volume and manner of sale
limitations under Rule 144.
 
    In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who beneficially owns shares last acquired
privately from the Company or an Affiliate at least one year previously is
entitled to sell, in "brokers' transactions" or to market makers, within any
three-month period commencing 90 days after the date of this Prospectus, a
number of shares that does not exceed the greater of (i) 1% of the then
outstanding shares of Common Stock (approximately 69,000 shares immediately
after the offering); or (ii) the average weekly trading volume in the Common
Stock during the four calendar weeks preceding the required filing of a Form 144
with respect to such sale. Sales under Rule 144 are generally subject to the
availability of current public information about the Company. Under Rule 144(k),
a person who is not deemed to have been an Affiliate of the Company at any time
during the 90 days preceding a sale, and who beneficially owns shares last
acquired from the Company or an Affiliate at least two years previously, is
entitled to sell such shares without complying with the manner of sale, public
 
                                       38
<PAGE>
information, volume limitation or notice provisions of Rule 144. Unless
otherwise restricted, "144(k) shares" may therefore be sold immediately upon the
consummation of this offering.
 
    Any employee, officer or director of or consultant to the Company who
purchased his or her shares pursuant to a written compensatory plan or contract
is entitled to rely on the resale provisions of Rule 701, which permits
non-Affiliates to sell their Rule 701 shares without complying with the public
information, holding period, volume limitation or notice provisions of Rule 144
and which permits Affiliates to sell their Rule 701 shares without complying
with the Rule 144 holding period restrictions, in each case commencing 90 days
after the date of this Prospectus.
 
    The Company intends to file, after expiration of the lockup agreements
referenced above, Registration Statements on Form S-8 under the Securities Act
to register shares of Common Stock reserved for issuance upon exercise of stock
options, thus permitting the resale of such shares by non-Affiliates in the
public market without restrictions under the Securities Act and by Affiliates
subject to volume and manner of sale limitations under Rule 144. As of the date
of this Prospectus, options to purchase 1,239,800 shares of Common Stock were
outstanding, with 915,200 of the shares issuable upon exercise of such options
subject to vesting requirements extending beyond the terms of the lock-up
agreements. The remaining 324,600 shares issuable upon exercise of such options
will become available for exercise and sale upon vesting and effectiveness of
such Registration Statements on Form S-8.
 
REGISTRATION RIGHTS
 
    The Company has entered into Registration Rights Agreements with certain
holders of Series A Convertible Preferred Stock granting them participatory and
demand registration rights with respect to the shares of Common Stock issuable
to them upon conversion of their shares of Series A Convertible Preferred Stock.
The participatory or "piggyback" rights provide that if the Company determines
to register for public sale with the U.S. Securities and Exchange Commission
certain of the Company's securities, the Company will use its best efforts to
cause the Common Stock acquired upon conversion of the Series A Convertible
Preferred Stock by such stockholders to be included in the offering for the
benefit of the investors desiring to sell such shares. The piggyback
registration rights relate to certain public offerings of the Company, if any,
occurring during a three-year period beginning on the closing of this offering.
Such registration rights are subject to various limitations, including the right
of the managing underwriter of a subsequent offering to determine that marketing
factors require a limitation on the number of shares of Common Stock that can be
sold by the selling stockholders participating in the registered sales and the
requirement that the selling stockholders pay their own selling expenses
(including selling commissions and stock transfer taxes) in connection with any
exercise of these piggyback rights.
 
    The demand registration rights provide that on a one-time basis only, during
a two and one-half year period beginning six months after the effective date of
this offering, upon the request of the holders of a majority in interest
thereof, the Company will promptly take all necessary action to register or
qualify for immediate sale, under the Securities Act and the securities laws of
such states as the holders may reasonably request, the Common Stock obtained
upon conversion. Selling stockholders will also be required to pay their own
selling expenses (including selling commissions and stock transfer taxes) in
connection with these demand rights.

</TABLE>
 
    The Underwriting Agreement provides that the several Underwriters will be
obligated to purchase all of the shares offered hereby, if any are purchased.
The obligation of the Underwriters to purchase the shares is several and not
joint meaning that, subject to the terms of the Underwriting Agreement, each
Underwriter is obligated to purchase only the number of shares set forth
opposite its name.
 
    The Underwriters propose to offer the shares to the public at the Price to
Public set forth on the cover page of this Prospectus and to dealers at such
price less a concession not in excess of $  per share. The Underwriters may
allow, and such dealers may reallow, a concession not in excess of $  per share
to certain other brokers and dealers. After the initial public offering, the
Price to Public, concession and reallowance may be changed by the
Representative.
 
    The Company has granted the Underwriters an option, exercisable within 30
days after the date of this Prospectus, to purchase up to an additional 300,000
shares at the Price to Public, less the Underwriting Discount and Commission
shown on the cover page of this Prospectus. The Underwriters may exercise such
option only for the purpose of covering any over-allotments in the sale of the
shares offered hereby.
 
    The Representative has informed the Company that the Underwriters do not
intend to confirm sales to any account over which they exercise discretionary
authority.
 
    The Underwriting Agreement provides for reciprocal indemnification between
the Company, the Underwriters and their controlling persons against civil
liabilities in connection with the offering, including liabilities under the
Securities Act. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted pursuant to the foregoing provisions, the
Company has been informed that, in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in such
Act and is therefore unenforceable.
 
    In order to facilitate the offering of Common Stock, the Underwriters may
engage in transactions that stabilize, maintain or otherwise affect the price of
Common Stock. Specifically, the Underwriters may over-allot Common Stock in
connection with the offering, creating a short position in Common Stock for
their own account. In addition, to cover over-allotments or to stabilize the
price of Common Stock, the Underwriters may bid for, and purchase, shares of
Common Stock in the open market. The Underwriters
 
                                       40
<PAGE>
may also reclaim selling concessions allowed to an underwriter or dealer for
distributing Common Stock in the offering, if the Underwriters repurchase
previously distributed Common Stock in transactions to cover their short
positions, in stabilization transactions or otherwise. Finally, the Underwriters
may bid for, and purchase, shares of Common Stock in market making transactions
and impose penalty bids. These activities may stabilize or maintain the market
price of Common Stock above the market level that may otherwise prevail. The
Underwriters are not required to engage in these activities and may end any of
these activities at any time.
 
    Prior to this offering, there has been no public trading market for the
Common Stock. The initial public offering price of the shares has been
determined by negotiations between the Company and the Representative. Among the
factors considered in such negotiations were the prevailing market conditions,
estimates of the business potential of the Company, the results of operations of
the Company in recent periods and other factors deemed to be relevant.
 
    The foregoing is a brief summary of the material provisions of the
Underwriting Agreement and does not purport to be a complete statement of their
terms and conditions. The Underwriting Agreement has been filed as an exhibit to
the Registration Statement of which this Prospectus is a part.
 
                                 LEGAL MATTERS
 
    The validity of the Common Stock offered hereby will be passed upon for the
Company by Fredrikson & Byron, P.A., Minneapolis, Minnesota. Certain legal
matters for the Underwriters will be passed upon by Oppenheimer Wolff &
Donnelly, Minneapolis, Minnesota.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To SurModics, Inc.:
 
    We have audited the accompanying balance sheets of SurModics, Inc. (a
Minnesota corporation) as of September 30, 1996 and 1997, and the related
statements of operations, stockholders' equity and cash flows for each of the
three years in the period ended September 30, 1997. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of SurModics, Inc. as of
September 30, 1996 and 1997, and the results of its operations and its cash
flows for each of the three years in the period ended September 30, 1997, in
conformity with generally accepted accounting principles.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    REVENUE RECOGNITION
 
    Royalties are recognized as third-party licensees report sales of the
product or as minimum royalties become due. Initial nonrefundable license fees
are recognized as revenue upon execution of the license agreement. Certain
nonrefundable license and research and development fees are recoverable by the
licensees as offsets against a percentage of future earned royalties. Revenues
on product sales are recognized as products are shipped and for research and
development as performance progresses under the applicable government contract
or commercial development agreement.
 
    Cash received prior to performance is recorded as deferred revenues in the
accompanying balance sheets. Deferred revenues also include advance payments
from a third-party licensee to the Company. The advance payments are being
applied as a reduction of amounts otherwise due for earned royalties up to
$75,000 per quarter and are expected to be fully absorbed during fiscal 1998.
 
    As of September 30, 1997, the Company had approximately $2.3 million of
signed government contracts on which work is yet to be performed and revenue has
yet to be earned.
 
    MAJOR CUSTOMERS
 
    Revenues from customers which exceed 10% of total revenues are as follows

    INCOME TAXES
 
    The Company utilizes the liability method to account for income taxes, and
deferred taxes are based on the estimated future tax effects of differences
between the financial statement and tax bases of assets and liabilities given
the provisions of the enacted tax laws.
 
    NET INCOME (LOSS) PER COMMON AND COMMON EQUIVALENT SHARE (PRO FORMA)
 
    Net income (loss) per common and common equivalent share (pro forma) was
computed by dividing net income (loss) by the weighted average common and common
stock equivalent shares outstanding (pro forma). Weighted average common and
common stock equivalent shares outstanding includes common shares outstanding,

prior to the proposed initial public offering at a price less than the proposed
public offering price using the treasury stock method.
 
    USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Ultimate results could differ from those estimates.
 
    NEW ACCOUNTING PRONOUNCEMENTS
 
    In March 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per
Share," which changes the way companies calculate their earnings per share
(EPS). SFAS No. 128 replaces primary EPS with basic EPS. Basic EPS is computed
by dividing reported earnings by weighted average shares outstanding, excluding
potentially dilutive securities. Fully diluted EPS, termed diluted EPS under
SFAS No. 128, is also to be disclosed. The Company is required to adopt SFAS No.
128 in fiscal 1998, at which time all prior year EPS are to be restated in
accordance with SFAS No. 128. If the Company had adopted the pronouncement
during fiscal 1997, the effect of this accounting change on reported EPS data
would have been as follows for the years ended September 30:

    Diluted EPS of the Company under SFAS No. 128 would be the same as primary
EPS as reported.
 
    In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which establishes standards for reporting and displaying comprehensive
income and its components in financial statements. The Company will adopt the
provisions of SFAS No. 130 in fiscal 1999.
 
    In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information," which establishes a new model for
segment reporting, called the "management approach" and requires certain
disclosures for each segment. The management approach is based on the way the
chief operating decision maker organizes segments within a company for making
operating decisions and assessing performance. The Company will be required to
adopt the provisions of SFAS No. 131 in fiscal 1999.

3. STOCKHOLDERS' EQUITY:
 
    AUTHORIZED SHARES
 
    The authorized capital stock of the Company consists of 20,450,000 shares of
capital stock, $0.05 per share par value, of which 15,000,000 shares are common
stock, 450,000 shares are Series A Convertible Preferred Stock and 5,000,000
shares are undesignated.
 
    STOCK SPLIT
 
    On December 22, 1997, the Company's board of directors approved a 4-for-1
stock split of all the Company's outstanding common stock. All share and per
share data have been restated for all periods presented to reflect the common
stock split.
 
    PREFERRED STOCK RIGHTS
 
    The Series A Convertible Preferred Stock has certain preferential
liquidation, conversion and dividend rights as follows:
 
a.  In the event of liquidation of the Company, the holders of these shares are
    entitled to receive $13.50 per share unless a greater amount would be
    distributed or paid with respect to each common share assuming the
    conversion of all outstanding preferred shares.
 
b.  Each preferred share is convertible, at the option of the holder, at any
    time into four shares of voting common stock, subject to adjustment, with
    automatic conversion upon the closing of a registered public offering
    meeting certain minimum parameters.
 
c.  Holders of preferred stock are entitled to receive dividends if, as and when
    declared by the board of directors.
 
    RESTRICTED STOCK AWARDS
 
    The Company has entered into restricted stock agreements with certain key
employees, covering the issuance of voting common stock (the Restricted Stock).
The Restricted Stock will be released to the key employees if they are employed
by the Company at the end of a five-year waiting period. Unearned compensation
has been recognized for the estimated fair value of the applicable common
shares, reflected as a reduction of stockholders' equity, and is being charged
to operations over the five-year waiting period.
 
    Transactions in restricted stock are as follows:

3. STOCKHOLDERS' EQUITY: (CONTINUED)
    STOCK PURCHASE NOTES RECEIVABLE
 
    The Company established a loan program during fiscal 1997 to assist
employees in purchasing shares of the Company's stock. The loans are
collateralized by the employees' purchased shares and require annual interest
payments at a rate equal to prime at the date of issuance, with principal and
any unpaid interest due at the earlier of five years after the date of issuance,
three months after termination of employment, or six months after the Company's
common stock becomes available to the public. Employees may borrow up to 100% of
the option price for the shares purchased or up to 100% of their previous
investment in the Company's stock.
 
4. STOCK-BASED COMPENSATION PLANS:
 
    Upon adoption of the Company's 1997 Incentive Stock Option Plan (the Plan),
which replaced the 1987 Incentive Stock Option Plan, 600,000 shares of voting
common stock were reserved for issuance to employees and officers. The Plan
requires that the option price per share cannot be less than 100% of the fair
market value of the common stock (as determined by the board of directors) on
the date of the grant of the option or 110% with respect to optionees who own
more than 10% of the total combined voting power of all classes of stock.
Options expire in five years or upon termination of employment and are
exercisable at a rate of 20% per year from the date of grant.
 
    Nonqualified options have been granted to outside directors, employees and
officers. The options have been granted at fair market value, as determined by
the board of directors at the date of grant. Options expire in five to ten years
and are exercisable at a rate of 20% per year from the date of grant or 20% per
year commencing two years after the date of grant.
 
    Information regarding stock options under all plans is summarized as
follows:

4. STOCK-BASED COMPENSATION PLANS: (CONTINUED)
    The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted-average
assumptions used for grants in 1996 and 1997, respectively: risk-free interest
rates of 6.43% and 6.24%; expected lives of 5 and 5.57 years; and expected
volatility of 73% for both years.
 
    The Company accounts for the options under APB Opinion No. 25, under which
no compensation cost has been recognized. Had compensation cost for the options
been determined consistent with SFAS No. 123, "Accounting for Stock-Based
Compensation," the Company's net income (loss) would have been the following pro
forma amounts for the years ended September 30:

    Because the SFAS No. 123 method of accounting has not been applied to

</TABLE>
 
    These deferred tax assets result from differences in the recognition of
transactions for income tax and financial reporting purposes. The principal
temporary differences relate to certain financial reserves not deductible for
tax purposes until paid, a capital loss carryforward and net operating loss
carryforwards.
 
    The Company's net operating loss carryforwards of approximately $6.4 million
at September 30, 1997 expire in varying amounts through 2011. Certain
restrictions under the Tax Reform Act of 1986, caused by the change in ownership
resulting from sales of common and convertible preferred stocks, may limit
annual utilization of the net operating loss carryforwards. The Company also has
$519,000 of capital loss carryforwards at September 30, 1997, which expire in
2001. A valuation allowance for the full amount of the deferred tax asset has
been established due to the uncertainty of realization.
 
    During fiscal 1997, the Company utilized $64,000 of net operating loss
carryforwards to offset the 1997 income tax liability.

area expenses and property taxes. The Company is responsible for maintenance,
insurance and other normal operating costs. Rental expense for the base monthly
payments and additional costs was approximately $280,000, $290,000 and $290,000

    GOVERNMENT CONTRACTS
 
    Under provisions contained in the government research contracts,
representatives of the government agencies have the right to access and review
the Company's underlying records of contract costs. The government retains the
right to reject expenses considered unallowable under the terms of the contract.
The Defense Contract Audit Agency has reviewed the contracts through 1989. In
the opinion of management, future amounts due, if any, with respect to open
contract years will not have a material impact on the financial position or
results of operations of the Company.
 
7. DEFINED CONTRIBUTION PLAN:
 
    The Company has a profit-sharing/401(k) retirement and savings plan for the
benefit of qualified employees. Under the plan, qualified employees may elect to
defer up to 15% of their compensation, subject to a maximum limit determined by
the Internal Revenue Service. The Company, at the discretion of the board of
directors, may elect to make an additional contribution. Contributions of
approximately $67,000, $78,000 and $86,000 have been charged to operations for
the years ended September 30, 1995, 1996 and 1997, respectively.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 302A.521, subd. 2, of the Minnesota Statutes requires the Company to
indemnify a person made or threatened to be made a party to a proceeding by
reason of the former or present official capacity of the person with respect to
the Company, against judgments, penalties, fines, including, without limitation,
excise taxes assessed against the person with respect to an employee benefit
plan, settlements, and reasonable expenses, including attorneys' fees and
disbursements, incurred by the person in connection with the proceeding with
respect to the same acts or omissions if such person (1) has not been
indemnified by another organization or employee benefit plan for the same
judgments, penalties or fines; (2) acted in good faith; (3) received no improper
personal benefit, and statutory procedure has been followed in the case of any
conflict of interest by a director; (4) in the case of a criminal proceeding,
had no reasonable cause to believe the conduct was unlawful; and (5) in the case
of acts or omissions occurring in the person's performance in the official
capacity of director or, for a person not a director, in the official capacity
of officer, board committee member or employee, reasonably believed that the
conduct was in the best interests of the Company, or, in the case of performance
by a director, officer or employee of the Company involving service as a
director, officer, partner, trustee, employee or agent of another organization
or employee benefit plan, reasonably believed that the conduct was not opposed
to the best interests of the Company. In addition, Section 302A.521, subd. 3,
requires payment by the Company, upon written request, of reasonable expenses in
advance of final disposition of the proceeding in certain instances. A decision
as to required indemnification is made by a disinterested majority of the Board
of Directors present at a meeting at which a disinterested quorum is present, or
by a designated committee of the Board, by special legal counsel, by the
stockholders, or by a court.
 
    Provisions regarding indemnification of officers and directors of the
Company are contained in Section 5.1 of the Bylaws (Exhibit 3.2 to this
Registration Statement). The Company is in the process of obtaining a director
and officer liability policy.
 
    Under Section 6 of the Underwriting Agreement, filed as Exhibit 1.1 hereto,
the Underwriters agree to indemnify, under certain conditions, the Company, its
directors, certain of its officers and persons who control the Company within
the meaning of the Securities Act against certain liabilities.
 
ITEM 25.  OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION.
 
    The following expenses will be paid by the Company in connection with the
distribution of the securities registered hereby and do not include the
underwriting discount to be paid to the Underwriters. All of such expenses,
except for the SEC registration fee, NASD fee and Nasdaq listing fee, are

ITEM 28.  UNDERTAKINGS.
 
    The undersigned Registrant hereby undertakes to provide to the underwriter
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriter to
permit prompt delivery to each purchaser.
 
    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 foregoing provisions, or
 
                                      II-3
<PAGE>
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 Securities Act of 1933 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
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
 
    The undersigned Registrant further undertakes that:
 
        (1) For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
    or 497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus 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.

    4.   COVENANTS OF THE COMPANY.


    The Company hereby covenants and agrees with each of the several
Underwriters as follows:

         (a)     If the Company has elected to rely on Rule 430A under the Act,
the Company will prepare and file a Prospectus (or term sheet within the meaning
of Rule 434 under the Act) containing the information omitted therefrom pursuant
to Rule 430A under the Act with the Commission within the time period required
by, and otherwise in accordance with the provisions of, Rules 424(b), 430A and
434, if applicable, under the Act; if the Company has elected to rely upon Rule
462(b) under the Act to increase the size of the offering registered under the
Act, the Company will prepare and file a registration statement with respect to
such increase with the Commission within the time period required by, and
otherwise in accordance with the provisions of, Rule 462(b) under the Act; the
Company will prepare and file with the Commission, promptly upon the request of
the Representative, any amendments or supplements to the Registration Statement
or Prospectus (including any term sheet within the meaning of Rule 434 under the
Act) that, in the opinion of the Representative, may be necessary or advisable
in connection with distribution of the Securities by Underwriters; and the
Company will not file any amendment or supplement to the Registration Statement
or Prospectus (including any term sheet within the meaning of Rule 434 under the
Act) to which the Representative shall reasonably object by notice to the
Company after having been furnished with a copy a reasonable time prior to the
filing.

         (b)     The Company will advise the Representatives promptly of (i)
any request of the Commission for amendment of the Registration Statement or for
supplement to the Prospectus or for any additional information, (ii) the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or the use of the Prospectus, (iii) the suspension of the
qualification of the Shares for offering or sale in any jurisdiction, or (iv)
the institution or threatening of any proceedings for that purpose, and the
Company will use its best efforts to prevent the issuance of any such stop order
preventing or suspending the use of the Prospectus or suspending such
qualification and to obtain as soon as possible the lifting thereof, if issued.

         (c)     The Company will promptly prepare and file at its own expense
with the Commission any amendments of, or supplements to, the Registration
Statement and the Prospectus which may be necessary in connection with the
distribution of the Shares by the Underwriters.  During the period when a
Prospectus relating to the Shares is required to be delivered under the Act, the
Company will promptly file any amendments of, or supplements to, the
Registration Statement and the Prospectus which may be necessary to correct any
untrue statement of a material fact or any omission to state any material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.  The Company will not file any amendment
of, or supplement to, the Registration Statement or Prospectus, after the
Effective Date, which shall not previously have been submitted to the
Representative and its counsel a reasonable time prior to such proposed filing
or to which the Representative shall have reasonably objected.  In case any
Underwriter is required to deliver a


                                         -12-

prospectus in connection with sales of any Shares at any time nine months or
more after the effective date of the Registration Statement, upon the request of
the Representative but at the expense of such Underwriter, the Company will
prepare and deliver to such Underwriter as many copies as the Representative may
request of an amended or supplemented Prospectus complying with Section 10(a)(3)
of the Act.

         (d)     The Company will endeavor to qualify the Shares for sale under
the securities laws of such jurisdictions as the Representative may reasonably
designate and the Company will file such consents to service of process or other
documents necessary or appropriate in order to effect such qualification or
registration.  In each jurisdiction in which the Shares shall have been
qualified or registered as above provided, the Company will continue such
qualifications or registrations in effect for so long as may be required for
purposes of the distribution of the Shares and make and file such statements and
reports in each year as are or may be reasonably required by the laws of such
jurisdiction to permit secondary trading of the same; provided, however, that in
no event shall the Company be obligated to qualify to do business in any
jurisdiction where it is not now so qualified or to take any action which would
subject it to the service of process in suits, other than those arising out of
the offering or sale of the Shares.

         (e)     The Company will furnish to the Representative, as soon as
available, copies of the Registration Statement and all amendments (two of which
will be signed and which shall include all exhibits), each Preliminary
Prospectus, if any, the Prospectus and any amendments or supplements to such
documents including any prospectus prepared to permit compliance with Section
10(a)(3) of the Act, all in such quantities as the Representative may from time
to time reasonably request.  The Company specifically authorizes the
Underwriters and all dealers to whom any of the Shares may be sold by the
Underwriters to use and distribute copies of such Preliminary Prospectuses and
Prospectuses in connection with the sale of the Shares as and to the extent
permitted by the federal and applicable state and local securities laws.

         (f)     The Company will make generally available to its security
holders an earnings statement, in a form complying with requirements of Section
11(a) of the Act and Rule 158 thereunder, as soon as practicable and in any
event not later than 45 days after the end of its fiscal quarter in which occurs
the first anniversary date of the Effective Date, meeting the requirements of
Section 11(a) of the Act covering a period of at least 12 consecutive months
beginning after the Effective Date, and will advise you in writing when such
statement has been so made available.

         (g)     The Company will, for such period up to five years from the
First Closing Date, deliver to the Representatives copies of its annual report
and copies of all other documents, and information furnished by the Company to
its security holders or filed with any securities exchange pursuant to the
requirements of such exchange or with the Commission pursuant to the Act or the
Exchange Act, or any state securities commission by the Company.  The Company
will deliver to the Representatives similar reports with respect to significant
subsidiaries, if any, as that term is defined in the rules and regulations under
the Act, which are not consolidated in the Company's financial statements.

to, any of the foregoing; (viii) the NASD filing fee; (ix) all fees and expenses
of counsel for the Representative incurred in qualifying the Shares for sale
under the laws of such jurisdictions designated by the Representative (including
filing fees).

         (j)     The Company will not take, and will use its best efforts to
cause each of its officers and directors not to take, directly or indirectly,
any action designed to or which might reasonably be expected to cause or result
in the stabilization or manipulation of the price of any security of the Company
to facilitate the sale or resale of the Shares and will not effect any sales of

performed each condition to closing required to be performed by the Company
pursuant to Section 5 hereof.

circumstances under which they were made, not misleading; provided, however,
that this Section 5(b) shall not apply to statements in, or omissions from, the
Registration Statement or Prospectus or any amendment thereof or supplement
thereto, which are based upon and conform to written information furnished to
the Company by any of the Underwriters specifically for use in the preparation
of the Registration Statement or the Prospectus, or any such amendment or
supplement.

         (c)     Subsequent to the Effective Date, and except as contemplated
or referred to in the Prospectus, the Company shall not have incurred any direct
or contingent liabilities or obligations material to the Company, or entered
into any material transactions, except liabilities, obligations or transactions
in the ordinary course of business, or declared or paid any dividends or made
any distribution of any kind with respect to its capital stock; and there shall
not have been any change in the capital stock (other than a change in the number
of outstanding shares of Common Stock due to the exercise of options or warrants
described in the Registration Statement and the Prospectus), or any change in
the short-term debt or long-term debt (including capitalized lease obligations)
of the Company, or any issuance of options, warrants, convertible securities or
other rights to purchase the capital stock of the Company or any change or any
development involving a prospective change in or affecting the general affairs,
management, financial position, shareholders' equity or results of operations of
the Company, otherwise than as set forth or contemplated in the Prospectus, the
effect of which, in the judgment of the Representatives


                                         -15-
<PAGE>

makes it impracticable or inadvisable to proceed with the public offering or the
delivery of the Shares being delivered.

         (d)     The Representative shall have received the opinion of
Fredrikson & Byron, P.A., counsel for the Company, dated the First Closing Date
or the Second Closing Date, as the case may be, addressed to the Underwriters
covering certain corporate matters to the effect that:

                 (i)    The Company as been duly incorporated and is validly
         existing in good standing under the laws of the State of Minnesota;
         has the corporate power to own, lease and operate its properties and
         conduct its businesses as described in the Prospectus; and is duly
         qualified to do business as a foreign corporation in good standing in
         all jurisdictions where the ownership or leasing of its properties or
         the conduct of its business requires such qualification and in which
         the failure to be so qualified or in good standing would have a
         material adverse effect on condition (financial or otherwise),
         shareholders' equity, results of operations, business, properties or
         prospects of the Company.

                 (ii)   The Company has the number of authorized and
         outstanding shares of capital stock of the Company as set forth under
         the caption "Capitalization" of the Prospectus, and all issued and
         outstanding capital stock of the Company has been duly authorized and
         is validly issued, fully paid and nonassessable.  There are no
         statutory preemptive rights, or to the best knowledge of such counsel,
         no similar subscription or purchase rights of securities holders of
         the Company with respect to issuance or sale of the Shares by the
         Company pursuant to this Agreement, and no rights to require
         registration of shares of Common Stock or other securities of the
         Company because of the filing of the Registration Statement exist.
         The Shares conform as to matters of law in all material respects to
         the description of such made in the Prospectus, and such description
         accurately sets forth the material legal provisions thereof required
         to be set forth in the Prospectus.

                 (iii)  The Shares have been duly authorized and, upon delivery
         to the Underwriters against payment therefor, will be validly issued,
         fully paid and nonassessable.

                 (iv)   The certificates evidencing the Shares comply as to
         form with the applicable provisions of the laws of the State of
         Minnesota.

                 (v)    The Registration Statement has become effective under
         the Act and, to the knowledge of such counsel, no stop orders
         suspending the effectiveness of the Registration Statement have been
         issued and no proceedings for that purpose have been instituted or are
         pending or, to the knowledge of such counsel, contemplated under the
         Act.

                 (vi)   To such counsel's knowledge, there are not material
         legal or


                                         -16-
<PAGE>

         governmental proceedings, pending or threatened, before any court or
         administrative body or regulatory agency, to which the Company or its
         affiliates is a party or to which any of the properties of the Company
         or its affiliates are subject that are required to be disclosed in the
         Registration Statement or Prospectus that are not so described, or
         statutes, regulations, or legal or governmental proceedings that are
         required to be described in the Registration Statement or Prospectus
         that are not so described.

                 (vii)  To such counsel's knowledge, there are no franchises,
         leases, contracts, agreements or documents of a character required to
         be disclosed in the Registration Statement or Prospectus or to be
         filed as exhibits to the Registration Statement or required to be
         incorporated by reference into the Prospectus which are not disclosed
         or filed or incorporated by reference, as required.

                 (viii) No authorization, approval or consent of any
         governmental authority or agency is necessary in connection with the
         issuance and sale of the Shares as contemplated under this Agreement,
         except such as may be required under the Act or under state or other
         securities laws in connection with the purchase and distribution of
         the Shares by the Underwriters.

                 (ix)   The Registration Statement and the Prospectus and any
         amendments thereof or supplements thereto (other than the financial
         statements and schedules and supporting financial and statistical data
         and information included or incorporated therein, as to which such
         counsel need express no opinion) conform in all material respects with
         the requirements of the Act and the Rules and Regulations, and the
         conditions for use of a registration statement on Form SB-2 for the
         distribution of the Shares have been satisfied with respect to the
         Company.

                 (x)    The statements (i) in the Prospectus under the caption
         "Risk Factors -- Government Regulation," "-- Hazardous Materials,"
         "--Anti-Takeover Laws," "-- Potential Adverse Market Impact of Shares
         Eligible for Future Sale," "Business -- Current Licensing
         Arrangements," "-- Government Regulation," "-- Facilities," "-- Legal
         Proceeding," "Management - Stock Option Plan," "Description of Capital
         Stock," "Shares Eligible for Future Sale" and (ii) in the Registration
         Statement in Item 14 insofar as such statements constitute a summary
         of statutes, legal and governmental proceeding contracts and other
         documents, are accurate summaries and fairly present the information
         called for with respect to such matters.

                 (xi)   Such counsel does not know of any contracts,
         agreements, documents or instruments required to be filed as exhibits
         to the Registration Statement or described in the Registration
         Statement or the Prospectus which are not so filed or described as
         required, and does not know of any amendment to the Registration
         Statement required to be filed that has not been filed; and insofar as


                                         -17-
<PAGE>

         any statements in the Registration Statement or the Prospectus
         constitute summaries of any contract, agreement, document or
         instrument to which the Company is a party, such statements are
         accurate summaries and fairly present the information called for with
         respect to such matters.

                 (xii)  To such counsel's knowledge, there are no defects in
         title or leasehold interests, or any liens, encumbrances, equities,
         charges or claims, not disclosed in the Registration Statement or
         Prospectus which would materially affect the present occupancy or use
         of any of the real or personal property owned or leased by the
         Company.

                 (xiii) The Company has the corporate power and authorization
         to enter this Agreement and to authorize, issue and sell the Shares as
         contemplated hereby.  This Agreement has been duly authorized,
         executed and delivered by, and is a valid and binding agreement of the
         Company, enforceable in accordance with its terms, except as
         enforceability may be limited by the application of bankruptcy,
         insolvency, moratorium or similar laws affecting the rights of
         creditors generally and judicial limitations on the right of specific
         performance and other equitable remedies and except as the
         enforceability of indemnification or contribution provisions hereof
         may be limited by action of a court interpreting or applying federal
         or state securities laws or equitable principles.

                 (xiv)  The performance of this Agreement and the consummation
         of the transactions described herein will not result in a violation of
         or default under, the Company's [AMENDED AND RESTATED] Articles of
         Incorporation, Bylaws or other governing documents.  To the best of
         such counsel's knowledge, (a) the Company is not in violation of, or
         in default under, its [AMENDED AND RESTATED] Articles of
         Incorporation, Bylaws or other governing documents; and (b) the
         performance of this Agreement and the consummation of the transactions
         described herein will not result in a material violation of, or a
         material default under, the terms or provisions of (A) any bond,
         debenture, note, or other evidence of indebtedness or any contract,
         license, indenture, mortgage, loan agreement, joint venture or
         partnership agreement, lease, agreement or instrument to which the
         Company is a party or by which the Company or any of its properties is
         bound, or (B) any law, order, rule, regulation, writ, injunction, or
         decree known to such counsel of any government, governmental agency or
         court having jurisdiction over the Company or any of its properties.

                 (xv)   To such counsel's knowledge, sales of unregistered
         securities by the Company prior to the Effective Date were exempt from
         registration requirements of the Act and are not required to be
         integrated, under Rule 502(a) of Regulation D of the Act, with the
         public offering contemplated hereby.


                                         -18-

                 (xvi)  The Company is not, and immediately upon completion of
         the sale of the Shares contemplated hereby will not be required to
         register as an "investment company" under the Investment Company Act
         of 1940, as amended.

                 (xvii) To the best of such counsel's knowledge, the Company is
         not engaged in any negotiations regarding any form of business
         combination with an other entity.

         In expressing the foregoing opinion, as to matters of fact relevant to
conclusions of law, counsel may rely, to the extent that they deem proper, upon
certificates of public officials and of the officers of the Company, and
opinions of other legal counsel to the Company, provided that copies of all such
certificates and opinions are attached to the opinion.

         In addition to the matters set forth above, such opinion shall also
include a statement to the effect that, although such counsel cannot guarantee
the accuracy, completeness or fairness of any of the statements contained in the
Registration Statement or Prospectus, in connection with such counsel's
representation, investigation and due inquiry of the Company in the preparation
of the Registration Statement and Prospectus, such counsel has no reason to
believe that, (i) as of its Effective Date, the Registration Statement or any
further amendment thereto (other than the financial statements and related
schedules therein, as to which such counsel need express no opinion) made by the
Company prior to the First Closing Date or the Second Closing Date, as the case
may be, contained an untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or (ii), as of its date, the Prospectus or any further
amendment or supplement thereto (other than the financial statements and related
schedules therein, as to which such counsel need express no opinion) made by the
Company prior to the First Closing Date or the Second Closing Date, as the case
may be, contained an untrue statement of a material fact or omitted to state a
material fact necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading or (iii), as of the First
Closing Date or the Second Closing Date, as the case may be, either the
Registration Statement or the Prospectus or any further amendment or supplement
thereto (other than the financial statements and related schedules therein, as
to which such counsel need express no opinion) made by the Company prior to the
First Closing Date or the Second Closing Date, as the case may be, contains an
untrue statement of a material fact or omits to state a material fact necessary
to make the statements therein, in light of the circumstances in which they were
made, not misleading.

         (e)     The Representative shall have received on the First Closing
Date or the Second Closing Date, as the case may be, the opinion of Fredrikson &
Byron, P.A., intellectual property counsel for the Company, dated the First

                                         -19-
<PAGE>

sufficiency of corporate proceedings and other legal matters relating to this
Agreement and the transactions contemplated hereby, and other related matters as
the Representative may reasonably request; and the Company and its counsel shall
have furnished to said counsel such documents as they may have reasonably
requested for the purpose of enabling them to pass upon such matters.  In
connection with such opinion, as to matters of fact relevant to conclusions of
law, such counsel may rely, to the extent that they deem proper, upon
representations or certificates of public officials and of responsible officers
of the Company.

         (g)     The Representative and the Company shall have received
letters, dated the date hereof and the First Closing Date and the Second Closing

         Registration Statement has been issued, and no proceeding for that
         purpose has been instituted or is pending or to the best knowledge of
         such officers contemplated under the Act.

                 (iii)   Neither the Registration Statement nor the Prospectus
         nor any amendment thereof or supplement thereto includes any untrue
         statement of a material fact or omits 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, and, since the Effective Date, there has occurred no event
         required to be set forth in an amended or supplemented prospectus
         which has not been so set forth; provided, however, that such
         certificate does not require any representation concerning statements
         in, or omissions from, the Registration Statement or Prospectus or any
         amendment thereof or supplement thereto, which are based upon and

claims, damages or liabilities, joint or several, to which such Underwriter or
each such person may become subject, under the Act, the Exchange Act, the common
law or otherwise, insofar as such losses, claims, damages or liabilities (or

omission purchased the Shares from such Underwriter and was not sent or given a
copy of the Prospectus with, or prior to, the written confirmation of the sale
of such Shares to such person by such Underwriter unless such failure to deliver

liability which the Company may otherwise have.

Prospectus, including any amendment thereof, (ii) the omission or alleged
omission to state in the Registration Statement, any Preliminary Prospectus or
Prospectus including any amendment thereof a material fact required to be stated

circumstances under which they were made, not misleading; or (iii) any untrue
statement or alleged untrue statement of a material fact contained in any
application or other statement executed by the Company or by any Underwriter and
filed in any jurisdiction in order to qualify the Shares under, or exempt the
Shares or the sale thereof from qualification under, the securities laws of such
jurisdiction, or the omission or alleged omission to state in such application
or statement a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading; in each of the above cases to the extent, but only the
extent, that such untrue statement, alleged untrue statement, omission or
alleged omission, was made in reliance upon and in conformity with information
furnished to the Company by, or on behalf of, any


                                         -23-
<PAGE>

Underwriter in writing specifically for use in the preparation of the
Registration Statement or any such post effective amendment thereof, any such
Preliminary Prospectus or the Prospectus or any such amendment thereof or
supplement thereto, or in any application or other statement executed by the
Company or by any Underwriter and filed in any jurisdiction; and each
Underwriter will reimburse any legal or other expenses reasonably incurred by
the Company or any such director, officer or controlling person in connection
with investigating or defending against any such loss, claim, damage, liability
or action as such expenses are incurred.  This indemnity agreement is in
addition to any liability which the Underwriters may otherwise have.

         (c)     Promptly after receipt by an indemnified party under this
Section 6 of notice of the commencement of any action or proceeding (including
any governmental investigation), such indemnified party will, if a claim in
respect thereof is to be made against any indemnifying party under this Section
6, notify in writing the indemnifying party of the commencement thereof.  The
failure to so notify the indemnifying party will not relieve such party from any
liability under this Section 6 as to the particular item for which
indemnification is then being sought, unless such failure so to notify
prejudices the indemnifying party's ability to defend such action.  In case any
such action is brought against any indemnified party and the indemnified party
notifies an indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel who shall be reasonably satisfactory to such
indemnified party; and 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 under this
Section 6 for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation; provided, however, that if, in the reasonable judgment
of the indemnified party, it is advisable for such parties and controlling
persons to be represented by separate counsel, any indemnified party shall have
the right to employ separate counsel to represent it and all other parties and
their controlling persons who may be subject to liability arising out of any
claim in respect of which indemnity may be sought by the Underwriters against
the Company or by the Company against the Underwriters hereunder, in which event
the fees and expenses of such separate counsel shall be borne by the
indemnifying party; provided, however, if the indemnified party shall have
reasonably concluded that there may be legal defenses available to it and/or
other indemnified parties which are different from or additional to those
available to the indemnifying party, or the indemnified and indemnifying parties
may have conflicting interests which would make it inappropriate for the same
counsel to represent both of them, the indemnified party shall have the right to
select separate counsel to assume such defense and to otherwise participate in
the defense of such action on behalf of such indemnified party and all other
parties and their controlling persons.  Any such indemnifying party shall not be
liable to any such indemnified party on account of any settlement of any claim
or action effected without the consent of such indemnifying party.

    7.   CONTRIBUTION.

         (a)     If the indemnification provided for in Section 6 is
unavailable or insufficient to hold harmless any indemnified party in respect of
any losses, claims, damages or


                                         -24-
<PAGE>

liabilities referred to therein, then each indemnifying party shall contribute
to the amount paid or payable by such indemnified party as a result of such
losses, claims, damages or liabilities in such proportion as is appropriate to
reflect the relative benefits received by the Company and the Underwriters from
the offering of the Shares.  In the event that the allocation provided by the
immediately preceding sentence is not permitted by applicable law, then each
indemnifying party shall contribute in such proportion as is appropriate to
reflect not only the relative benefits referred to above but also the relative
fault of the Company and the Underwriters in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations.  The Company and the
Underwriters agree that contribution determined by per capita allocation (even
if the Underwriters were considered a single person) would not be equitable.
The respective relative benefits received by the Company on the one hand, and
the Underwriters, on the other, shall be deemed to be in the same proportion (a)
in the case of the Company, as the total price paid to the Company for the
Shares by the Underwriters (net of underwriting discount received but before
deducting expenses) bears to the aggregate Offering Price of the Shares, and (b)
in the case of the Underwriters, as the aggregate underwriting discount received
by them bears to the aggregate Offering Price of the Shares, in each case as
reflected in the Prospectus.  The relative fault of the Company and the
Underwriters shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or by the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.  The amount paid or payable by a party as a result of the losses,
claims, damages and liabilities referred to above shall be deemed to include any
legal or other fees or expenses reasonably incurred by such party in connection
with investigating or defending any action or claim.  Notwithstanding the
provisions of this Section 7, no Underwriter shall be required to contribute any
amount in excess of the amount by which the total price at which the Shares
underwritten by it were offered to the public exceeds the amount of any damages
which such Underwriter has otherwise been required to pay by reason of any
untrue or alleged untrue statement or omission or alleged omission in the
Registration Statement, any Preliminary Prospectus, the Prospectus or any
amendment or supplement thereto.  The Underwriters' obligation to contribute
pursuant to this Section 7 is several and not joint.  No person guilty of
fraudulent misrepresentation (within the meaning of the Act) shall be entitled
to contribution from any person who was not guilty of such fraudulent
misrepresentation.  For purposes of this Section 7, each person who controls an
Underwriter within the meaning of the Act or the Exchange Act shall have the
same rights to contribution as such Underwriter, each person who controls the
Company within the meaning of the Act or the Exchange Act shall have the same
rights to contribution as the Company and each officer of the Company who shall
have signed the Registration Statement and each director of the Company shall
have the same rights to contribution as the Company.

         (b)     Promptly after receipt by a party to this Agreement of notice
of the commencement of any action, suit, or proceeding, such person will, if a
claim for contribution in respect thereof is to be made against another party
(the "Contributing Party"), notify the Contributing Party of the commencement
thereof, but the failure to so notify the Contributing Party will not relieve
the Contributing Party from any liability which it may have to any party


                                         -25-
<PAGE>

other than under this Section 7, unless such failure to so notify prejudices the
Contributing Party's ability to defend such action. Any notice given pursuant to
Section 6 hereof shall be deemed to be like notice hereunder.  In case any such
action, suit or proceeding is brought against any party, and such person
notifies a Contributing Party of the commencement thereof, the Contributing
Party will be entitled to participate therein with the notifying party and any
other Contributing Party similarly notified.

         (c)     The obligations of the Company under this Section 7 shall be
in addition to any liability which the Company may otherwise have, and the
obligations of the Underwriter under this Section 7 shall be in addition to any
liability which the Underwriters may otherwise have.


8.  EFFECTIVE DATE AND TERMINATION.

         (a)     This Agreement shall become effective at the later of (i) the
day upon which this Agreement shall have been executed and delivered by the
parties hereto, or (ii) (ii) at 10:00 a.m. Minneapolis time, on the first full
business day following the Effective Date, or at such earlier time after the
Effective Date as the Representative in its discretion shall first release the
Shares for offering to the public. For purposes of this Section 8, the Shares
shall be deemed to have been released to the public upon release by the
Representative of the publication of a newspaper advertisement relating to the
Shares or upon release of a telegram or a letter offering the Shares for sale to
securities dealers, whichever shall first occur.

         (b)     The Representative shall have the right to terminate this
Agreement by giving notice to the Company as hereinafter specified at any time
prior to the First Closing Date, and the option referred to in Section 2(b), if
exercised, may be canceled at any time by the Representative by giving such
notice to the Company at any time prior to the Second Closing Date, if (i) the
Company shall have failed, refused or been unable, at or prior to the First
Closing Date, to perform any material agreement on its part to be performed
hereunder; (ii) any other condition of the Underwriters' obligations hereunder
is not fulfilled; (iii) trading in securities generally on the New York Stock
Exchange, American Stock Exchange or the Nasdaq Stock Market shall have been
suspended, or minimum or maximum prices for trading shall have been required or
established by the Commission or by any such exchange or the Nasdaq Stock
Market; (iv) a banking moratorium shall have been declared by federal, New York
or Minnesota authorities; (v) there shall have been such a material adverse
change in general economic, monetary, political or financial conditions, or the
effect of international conditions on the financial markets in the United States
shall be such as, in the judgment of the Representative, makes it impracticable
or inadvisable to proceed with the completion of the sale of and payment for the
Shares; (vi) there shall have been the enactment, publication, decree or other
promulgation of any federal or state statute, regulation, rule or order of any
court or other governmental authority, which in the judgment of the
Representative materially and adversely affects or will materially and adversely
affect the business or operations of the Company; or (vii) there shall be an
outbreak of major hostilities (or an escalation thereof) in which the United
States is involved or a formal declaration of war by the United States of
America shall have occurred or any other substantial national or international
calamity or any other event or


                                         -26-
<PAGE>

occurrence of a similar character shall have occurred since the execution of
this Agreement that, in the judgment of the Representative, makes it
impracticable or inadvisable to proceed with the completion of the sale of and
payment for the Shares. Any such termination shall be without liability of any
party to any other party, except as provided in Sections 6 and 7 hereof;
provided, however, that the Company shall remain obligated to pay costs and
expenses to the extent provided in Section 4(i) hereof.

         (c)     If the Representative elects to prevent this Agreement from
becoming effective or to terminate this Agreement as provided in this Section 8,
it shall notify the Company promptly by telecopy or telephone, confirmed by
letter sent to the address specified in Section 11 hereof.  If the Company shall
elect to prevent this Agreement from becoming effective, it shall notify the
Representative promptly by telecopy or telephone, confirmed by letter sent to
the address specified in Section 11 hereof.

         (d)     If the Company shall fail at the First Closing Date to sell
and deliver the number of Shares which it is obligated to sell hereunder, then
this Agreement shall terminate without any liability on the part of any
Underwriter. No action taken pursuant to this Section 8(d) shall relieve the
Company from liability, if any, in respect of such default.


    9.   DEFAULT OF UNDERWRITER.


    If on the First Closing Date or the Second Closing Date, as the case may
be, any Underwriter shall fail to purchase and pay for the portion of the Shares
which such Underwriter has agreed to purchase and pay for on such date
(otherwise than by reason of any default on the part of the Company), you, as
Representative of the Underwriters, shall use your best efforts to procure
within 36 hours thereafter one or more of the other Underwriters, or any others,
to purchase from the Company such amounts as may be agreed upon, and upon the
terms set fort herein, of the Firm Shares or Option Shares, as the case may be,
which the defaulting Underwriter or Underwriters failed to purchase. If during
such 36 hours you, as Representative, shall not have procured such other
Underwriters, or any others, to purchase the Firm Shares or Option Shares, as
the case may be, agreed to be purchased by the defaulting Underwriter or
Underwriters, then (i) if the aggregate number of Shares with respect to which
such default shall occur does no exceed 10% of the Firm Shares or Option Shares,
as the case may be, covered hereby the other Underwriters shall be obligated,
severally, in proportion to the respective numbers of Firm Shares or Option
Shares, as the case may be, which they are obligated to purchase hereunder, to
purchase the Firm Shares or Option Shares, as the case may be, which such
defaulting Underwriter or Underwriters failed to purchase or (ii) if the
aggregate number of shares of Firm Shares or Option Shares, as the case may be,
with respect to which such default shall occur exceeds 10% of the Firm Shares or
Option Shares, as the case may be, covered hereby, the Company or you as the
Representative of the Underwriters will have the right, by written notice given
within the next 36-hour period to the parties to this Agreement, to terminate
this Agreement without liability on the part of the non-defaulting Underwriters
or of the Company except for expenses to be borne by the Company and the
Underwriters as provided in Section 4(i) hereof and the indemnity and
contribution agreements in Sections 6 and 7 hereof. In


                                         -27-
<PAGE>

the event of a default by any Underwriter or Underwriters, as set forth in this
Section 9, the First Closing Date or Second Closing Date, as the case may be,
may be postponed for such period, not exceeding seven days, as you, as
Representatives, may determine in order that the required changes, not including
a reduction in the number of Firm Shares, in the Registration Statement or in
the Prospectus or in any other documents or arrangements may be effected.  The
term "Underwriter" includes any person substituted for a defaulting Underwriter.
Any action taken under this Section 9 shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

    10.  SURVIVAL.

    The respective indemnity and contribution agreements of the Company and the
Underwriters contained in Sections 6 and 7, respectively, the representations
and warranties of the Company set forth in Section 1 hereof and the covenants of
the Company set forth in Section 4 hereof shall remain operative and in full
force and effect, regardless of any investigation made by, or on behalf of, the
Underwriters, the Company, any of its officers and directors or any controlling
person referred to in Sections 6 and 7 and shall survive the delivery of and
payment for the Shares.  The aforesaid indemnity and contribution agreements
shall also survive any termination or cancellation of this Agreement.  Any
successor of any party or of any such controlling person, or any legal
representative of such controlling person, as the case may be, shall be entitled
to the benefit of the respective indemnity and contribution agreements.

    11.  NOTICES.

    All notices or communications hereunder, except as herein otherwise
specifically provided, shall be in writing and, if sent to the Representative or
any of the Underwriters, shall be mailed, delivered, or telecopied and

     The rights, preferences, privileges and restrictions granted to or imposed
upon the Capital Stock or the holders thereof are set forth below.

     4.1)  VOTING PRIVILEGES.  Each holder of Voting Common Stock shall have one
vote on all matters submitted to the shareholders for each share of Voting
Common Stock standing in the name of such holder on the books of the
corporation.  Each holder of Preferred Stock shall have one vote on all matters
submitted to the shareholders for each share of Voting Common Stock which such
holder of Preferred Stock would be entitled to receive upon the conversion of
his Preferred Stock as provided in subsection 4.5(c). In addition, each holder
of Preferred Stock shall have the special voting rights which are described in
subsection 4.5(b). Except as may be required by the Minnesota Business
Corporation Act, the holders of Nonvoting Common Stock shall have no voting
rights with respect to any matter submitted to a vote of the shareholders of the
corporation.

     4.2)  PREEMPTIVE RIGHTS.  No holder of shares of any class or series of
Capital Stock shall be entitled as such, as a matter of right, to subscribe for
or purchase additional shares of that class or series or any other class or
series of Capital Stock of the corporation now or hereafter authorized or
issued.

     4.3)  NO CUMULATIVE VOTING.  There shall be no cumulative voting by the
shareholders of the corporation.

     4.4)  DISTRIBUTIONS.  Except as provided in subsection 4.5(a) on the
liquidation, dissolution or winding up of the corporation, shares of Capital
Stock shall share ratably in any dividends or distributions of the corporation,
whether paid in cash, property or stock.

     4.5)  SERIES A CONVERTIBLE PREFERRED STOCK.

           (a)   LIQUIDATION PREFERENCE.  In the event of the liquidation,
     dissolution or winding up of the corporation, whether voluntary or
     involuntary, the holders of the Preferred Stock shall be entitled to
     receive out of assets of the corporation, an amount equal to $13.50
     (hereinafter referred to as the "Liquidation Preference") for each
     outstanding share of Preferred Stock before any payment shall be made or
     any assets distributed to the holders of Voting Common Stock or Nonvoting
     Common Stock or any other class of stock of this corporation ranking junior
     to the Preferred Stock upon liquidation or dissolution of the corporation.
     If, upon any liquidation, dissolution, or


                                        5
<PAGE>


     winding up of the corporation, the assets of the corporation are
     insufficient to pay the Liquidation Preference for each outstanding share
     of Preferred Stock, the holders of Preferred Stock shall share pro rata in
     any such distribution in proportion to the full amounts to which they would
     otherwise be entitled.  If, upon any liquidation, dissolution or winding up
     of the corporation, the holders of Preferred Stock would be entitled to
     receive in excess of the Liquidation Preference for each outstanding share
     of Preferred Stock in any such distribution if all such shares of Preferred
     Stock had been converted to shares of Voting Common Stock pursuant to
     subsection 4.5(c), instead of receiving the Liquidation Preference, each
     holder of Preferred Stock shall receive an amount equal to the distribution
     such holder would receive if all his outstanding shares of Preferred Stock
     had been converted to shares of Voting Common Stock pursuant to subsection
     4.5(c) on the day preceding the date of such liquidation, dissolution or
     winding up.  The Liquidation Preference shall be appropriately adjusted to
     reflect stock splits and reverse stock splits of the Preferred Stock or
     dividends or distributions payable in shares of Preferred Stock.

           Nothing hereinabove set forth shall affect in any way the right or
     obligation of each holder of shares of Preferred Stock to convert such
     shares into shares of Voting Common Stock, at any time and from time to
     time, in accordance with subsection 4.5(c) below.

           (b)   SPECIAL VOTING RIGHTS.  Without the affirmative vote of the
     holders (acting together as a class) of at least a majority of the
     Preferred Stock at the time outstanding given in person or by proxy at any
     annual meeting, or at such special meeting called for that purpose, or, if
     permitted by law, in writing without a meeting, the corporation shall not:

                 (1)   authorize or issue any shares of stock having priority
           over the Preferred Stock as to the payment of dividends or the
           payment or distribution of assets upon the liquidation or
           dissolution, voluntary or involuntary, of the corporation; or

                 (2)   amend the Articles of Incorporation of the corporation so
           as to alter this Article 4 in any respect.

           (c)   CONVERSION RIGHTS; MANDATORY CONVERSION.

                 (1)   At the option of the holder thereof, each share of
           Preferred Stock shall be convertible, at the offices of the
           corporation (or at such other office or offices, if any, as the Board
           of Directors may designate), into one (1) share of Voting Common
           Stock of the corporation, subject to adjustment as provided in
           subsection 4.5(c)(2) below.  In order to convert shares of Preferred
           Stock into shares of Voting Common Stock, the holder thereof, shall
           surrender at the principal executive offices of the corporation the
           certificate or certificates therefor, duly endorsed to the
           corporation or in blank, and give written notice to the corporation
           at such office that such holder elects to convert a specified portion
           or all of such shares of Preferred Stock into shares of Voting Common
           Stock.  Shares


                                        6
<PAGE>


           of Preferred Stock shall be deemed to have been converted on the day
           of surrender of the certificate representing such shares for
           conversion in accordance with the foregoing provisions (the
           "Conversion Date"), and the person entitled to receive the shares of
           Voting Common Stock of the corporation issuable upon such conversion
           shall be treated for all purposes as the record holder of such shares
           of Voting Common Stock at that time.  As promptly as practicable on
           or after the Conversion Date, the corporation shall issue and mail or
           deliver or cause to be issued and mailed or delivered to such holder
           a certificate or certificates for the number of shares of Voting
           Common Stock issuable upon conversion and a certificate or
           certificates for the balance of the Preferred Stock surrendered, if
           any, not so converted into shares of Voting Common Stock.

                 (2)   The number of shares of Voting Common Stock issuable in
           exchange for shares of Preferred Stock upon the exercise of these
           conversion rights (the "Conversion Ratio"), which shall initially be
           one share of Voting Common Stock for one share of Preferred Stock,
           shall be subject to adjustment from time to time as hereinafter
           provided:

                       (i)    In case the corporation shall at any time
                 subdivide or split its outstanding Common Stock into a greater
                 number of shares, the Conversion Ratio in effect immediately
                 prior to such subdivision or split shall be proportionately
                 increased; and, conversely, in case the outstanding Common
                 Stock of the corporation shall be combined into a smaller
                 number of shares the Conversion Ratio in effect immediately
                 prior to such combination shall be proportionately reduced.

                       (ii)   If any capital reorganization or reclassification
                 of the Capital Stock of the corporation or consolidation or
                 merger of the corporation with another corporation or the sale
                 of all or substantially all of its assets to another
                 corporation shall be affected in such a way that holders of
                 Common Stock shall be entitled to receive stock, securities or
                 assets with respect to or in exchange for Common Stock, then,
                 as a condition of such reorganization, reclassification,
                 consolidation, merger or sale, lawful and adequate provision
                 shall be made whereby the holders of Preferred Stock shall
                 thereafter have the right to receive, in lieu of the Voting
                 Common Stock of the corporation immediately theretofore
                 receivable upon the conversion of any such Preferred Stock,
                 such shares of stock, securities or assets as may be issued or
                 payable with respect to or in exchange for a number of
                 outstanding shares of Voting Common Stock equal to the number
                 of shares of Voting Common Stock immediately theretofore
                 receivable upon the conversion of such Preferred Stock had such
                 reorganization, reclassification, consolidation, merger or sale
                 not taken place; and, in any such case, appropriate provision
                 shall be made with respect to the rights and interests of the
                 holders of the Preferred Stock to the end that the provisions
                 hereof (including without limitation provisions


                                        7
<PAGE>


                 for adjustments of the Conversion Ratio and of the number of
                 shares receivable upon the conversion of such Preferred Stock)
                 shall thereafter be applicable as nearly as may be, in relation
                 to any shares of stock, securities or assets hereafter
                 receivable upon the conversion of such Preferred Stock.  The
                 corporation shall not effect any such consolidation, merger or
                 sale, unless prior to the consummation thereof the surviving
                 corporation (if other than the corporation), the corporation
                 resulting from such consolidation or the corporation purchasing
                 such assets shall ASSUME by written instrument executed and ma
                 i led to the registered holders of the Preferred Stock at the
                 last address of such holders appearing on the books of the
                 corporation, the obligation to deliver to such holders such
                 shares of stock, securities or assets as, in accordance with
                 the foregoing provisions, such holders may be entitled to
                 receive.

                       (iii)  If and whenever the corporation shall issue or
                 sell any Common Stock for a consideration per share less than
                 the Liquidation Preference (except for the issuance or sale of
                 up to 50,000 shares of Nonvoting Common Stock pursuant to the
                 corporation's 1984 Stock Option Plan, up to 200,000 shares of
                 Voting Common Stock pursuant to the corporation's 1987 Stock
                 Option Plan and up to 50,000 shares of Voting Common Stock to
                 Simplot Development Corporation (hereinafter referred to as the
                 "Excluded Stock Issuances")) or shall issue any options,
                 warrants or other rights for the purchase of shares of Common
                 Stock at a consideration per share of less than the Liquidation
                 Preference, forthwith upon such issuance or sale of such
                 shares, options, warrants or other rights for purchase, the
                 Conversion Ratio in effect immediately prior to such issuance
                 or sale for the Preferred Stock shall be adjusted so that each
                 share of Preferred Stock shall thereafter be convertible into
                 that number of shares of Voting Common Stock as is equal to the
                 number determined by multiplying the Conversion Ratio by a
                 fraction, the numerator of which shall be the amount determined
                 by multiplying (aa) the number of shares of Common Stock
                 outstanding immediately after such issuance or sale plus the
                 number of shares of Common Stock issuable upon the exercise of
                 any purchase rights thus issued, by (bb) the Liquidation
                 Preference, and the denominator of which shall be an amount
                 equal to the sum of (aa) the number of shares of Common Stock
                 outstanding immediately prior to such issuance or sale
                 multiplied by the Liquidation Preference, and (bb) the total
                 consideration payable to the corporation upon such issuance or
                 sale of such shares and such purchase rights and upon the
                 exercise of such purchase rights.  If any options or purchase
                 rights taken into account in any such adjustment of the
                 Conversion Ratio subsequently expire without exercise, the
                 Conversion Ratio shall be recomputed by deleting such options
                 or purchase rights.  For purposes of this subsection 4.5(c)(2),
                 the number of shares of Voting Common Stock or Nonvoting Common
                 Stock which may be issued as Excluded Stock Issuances shall be
                 appropriately adjusted to


                                        8
<PAGE>


                 reflect stock splits, stock dividends, reorganizations,
                 consolidations and similar changes.

                       (iv)   The anti-dilution provisions of this subsection
                 4.5(c)(2) may be waived by the affirmative vote of the holders
                 (acting together as a class) of at least a majority of the then
                 outstanding shares of Preferred Stock,

                 (3)   Upon receipt of a written notice to the corporation from
           a holder of shares of Preferred Stock delivered to the corporation's
           principal executive offices requesting a computation of the then
           current Conversion Ratio, the corporation shall promptly give written
           notice by first-class mail, postage prepaid, addressed to the holder
           of the Preferred Stock making such request at the address of such
           holder as shown on the books of the corporation which notice shall
           state the then current Conversion Ratio, setting forth in reasonable
           detail the method of calculation and the facts upon which such
           calculation is based.

                 (4)   In case any time:

                       (i)    the corporation shall pay any dividend payable in
                 stock upon its Common Stock or make any distribution (other
                 than regular cash dividends) to the holders of its Common
                 Stock; or

                       (ii)   the corporation shall offer for subscription pro
                 rata to the holders of its Common Stock any additional shares
                 of stock of any class or other rights; or

                       (iii)  there shall be any capital reorganization,
                 reclassification of the Capital Stock of the corporation or
                 consolidation or merger of the corporation with or sale of all
                 or substantially all of its assets to another corporation; or

                       (iv)   there shall be a voluntary or involuntary
                 dissolution, liquidation or winding up of the corporation;

           then in any one or more of said cases the corporation shall give
           written notice, by first-class mail, postage prepaid, addressed to
           the holders of the Preferred Stock at the addresses of such holders
           as shown on the books of this corporation, of the date on which (aa)
           the books of the corporation shall close or a record shall be taken
           for such dividend, distribution or subscription rights or (bb) such
           reorganization, reclassification, consolidation, merger, sale,
           dissolution, liquidation or winding up shall take place, as the case
           may be.  Such notice shall also specify the date as of which the 
           holders of Common Stock of record shall participate in such dividend,
           distribution or subscription rights or shall be entitled to exchange 
           their Common Stock for securities or other property deliverable upon 
           such reorganization, reclassification, consolidation, merger, sale,
           dissolution, liquidation


                                        9
<PAGE>


           or winding up, as the case may be.  Such written notice shall be 
           given at least 20 days prior to the action in question and not less 
           than 20 days prior to the record date or the date on which this 
           corporation's transfer books are closed in respect thereto.

                 (5)   As used in this subsection 4.5(c), the term Common Stock
           shall mean and include the corporation's presently authorized Voting
           Common Stock and Nonvoting Common Stock and shall also include any
           capital stock of any class of the corporation hereafter authorized
           which shall have the right to vote on all matters submitted to the
           shareholders of the corporation and shall not be limited to a fixed
           sum or percentage in respect of the rights of the holders thereof to
           participate in dividends or in the distribution of assets upon the
           voluntary or involuntary liquidation, dissolution or winding up of
           the corporation; provided that the shares receivable pursuant to
           conversion of the Preferred Stock shall include shares designated as
           Voting Common Stock of the corporation as of the date of issuance of
           such Preferred Stock or, in the case of any reclassification of the
           outstanding shares thereof, the stock, securities or assets provided
           for in subsection 4.5(c)(2)(ii) above.

                 (6)   The number of shares of Voting Common Stock issuable upon
           conversion of shares of Preferred Stock shall be computed to the
           nearest one hundredth of a full share; however, no fractional shares
           of Voting Common Stock shall be issued upon conversion.  The
           corporation shall pay a cash adjustment in respect of any fraction of
           a share in an amount-equal to the same fraction of the market price
           per share of Voting Common Stock as of the close of business on the
           day of conversion.  "Market price" shall mean the average of the high
           and low prices of the Voting Common Stock sales on all exchanges on
           which the Voting Common Stock may at the time be listed or as
           reported by the National Association of Securities Dealers, Inc.
           Automated Quotation System National Market System ("NASDAQ-NMS"), or,
           if there shall have been no sales on any such exchange or as reported
           by NASDAQ-NMS on any such day, the average of the bid and asked
           prices at the end of such day, or, if the Voting Common Stock shall
           not be so listed or transactions so reported, the average of the bid
           and asked prices at the end of the day in the over-the-counter
           market, in each case averaged over a period of 20 consecutive
           business days prior to the date as of which I, market price" is being
           determined.  If at any time the Voting Common Stock is not listed on
           any exchange, reported by NASDAQ-NMS or quote in the over-the-counter
           market, the "market price" shall be deemed to be the higher of (a)
           the book value thereof as determined by any firm of independent
           public accountants of recognized standing selected by the Board of
           Directors of the Corporation as of the last day of any month ending
           within 60 days preceding the date as of which the determination is to
           be made, or (b) the fair value thereof determined in good faith by
           the Board of Directors of the Corporation as of a date which is
           within 15 days of the date as of which the determination is to be
           made.

                 (7)   Notwithstanding the foregoing right to convert at the
           option of the holder, each share of Preferred Stock shall
           automatically be converted into the appropriate number of shares of
           Voting Common Stock of the corporation in the manner and upon the

forth the computation of the amount due from Lessee.  In the event the lease
term shall begin or expire at any time during the calendar year, the Lessee
shall be responsible for his prorata share of Additional Rent under subdivisions
a. and b. during the Lease and/or occupancy time.

calendar year thereafter commencing during the term of this Lease or any renewal
or extension thereof, Lessor may estimate for each calendar year (i) the total
amount of Real Estate Taxes; (ii) the total amount of Operating Expenses; (iii)
Lessee's share of Real Estate Taxes for such calendar year; (iv) Lessee's share
of Operating Expenses for such calendar year; and (v) the computation of the
annual and monthly rental payable during such calendar year as a result of
increases or decreases in Lessee's share of Real Estate Taxes, and Operating
Expenses.  Said estimates will be in writing and will be delivered or mailed to

    The amount of Lessee's share of Real Estate Taxes, and Operating Expenses
for each calendar year, so estimated, shall be payable as Additional Rent, in
equal monthly installments, in advance, on the first day of each month during
such calendar year at the option of Lessor.  In the event that such estimate is
delivered to Lessee before the first day of January of such calendar year, said
amount, so estimated, shall be payable as additional rent in equal monthly
installments, in advance, on the first day of each month during such calendar
year.  In the event that such estimate is delivered to Lessee after the first
day of January of such calendar year, said amount, so estimated, shall be
payable as additional rent in equal monthly installments, in advance, on the
first day of each month over the balance of such calendar year, with the number
of installments being equal to the number of full calendar months remaining in
such calendar year.

renewal or extension thereof, Lessor shall cause its accountants to determine
the actual amount of the Real Estate Taxes, and Operating Expenses payable in
such calendar year and Lessee's share thereof and deliver a written
certification of the amounts thereof to Lessee.  If Lessee has underpaid its
share of Real Estate Taxes, or Operating Expenses for such calendar year, Lessee
shall pay the balance of its share of same within ten (10) days after the
receipt of such statement.  If Lessee has overpaid its share of Real Estate
Taxes, or Operating Expenses for such calendar year, Lessor shall either (i)
refund such excess, or (ii) credit such excess against the most current monthly
installment or installments due Lessor for its estimate of Lessee's share of
Real Estate Taxes, and Operating Expenses for the next following calendar year. 
A pro rata adjustment shall be made for a calendar year occurring during the
term of this Lease or any renewal or extension thereof based upon the number of
days of the term of the Lease during said calendar year as compared to three
hundred sixty-five (365) days and all additional sums payable by Lessee or
credits due Lessee as a result of the provisions of this Article 3 shall be
adjusted accordingly.

indemnification as Lessor may reasonably require against liens, costs, damages
and expenses arising out of such alterations.  Alterations or additions by

to be held by Lessor, without liability for interest, as a security and damage

payable by Lessee to Lessor pursuant to the provisions of this Lease, damages or
deficiencies in the reletting of Demised Premises, and reasonable attorney's
fees incurred by Lessor.  Should the entire deposit or any portion thereof, be
appropriated and applied by Lessor, in accordance with the provisions of this
paragraph, Lessee upon written demand by Lessor, shall remit forthwith to Lessor
a sufficient amount of cash to restore said security deposit to the original sum
deposited, and Lessee's failure to do so within five (5) days after receipt of
such demand shall constitute a breach of this Lease.  Said security deposit
shall be returned to Lessee, less any depletion thereof as the result of the
provisions of this paragraph, at the end of the term of this Lease or any
renewal thereof, or upon the earlier termination of this Lease.  Lessee shall

required to be paid pursuant to the provision of this Lease or otherwise.

dispose of its interest in this Lease, Lessor may assign said security deposit
or any balance thereof to Lessor's assignee, whereupon Lessor shall be released
from all liability for the return or repayment of such security deposit and
Lessee shall look solely to the said assignee for the return and repayment of
said security deposit.  Said security deposit shall not be assigned or
encumbered by Lessee without such consent of Lessor, and any assignment or
encumbrance without such consent shall not bind Lessor.  In the event of any
rightful and permitted assignment of this Lease by Lessee, said security deposit
shall be deemed to be held by Lessor as a deposit made by the assignee, and
Lessor shall have no further liability with respect to the return of said
security deposit to the Lessee.

comply with any laws, ordinances, rules, regulations or requirements of any
public authority or of the Board of Fire Underwriters or any similar body or
that the Lessor may deem necessary to prevent waste or deterioration in
connection with the Demised Premises.  Nothing herein shall imply any duty upon
the part of the Lessor to do any such work which, under any provision of this
Lease, the Lessee may be required to perform and the performance thereof by the
Lessor shall not constitute a waiver of the Lessee's default in failing to
perform the same.  The Lessor may, during the progress of any work in the
Demised Premises, keep and store upon the Demised Premises all necessary
materials, tools and equipment.  The Lessor shall not in any event be liable for
inconvenience, annoyance, disturbance, loss of  business, or other damage of the
Lessee by reason of making repairs or the performance or any work in the Demised
Premises, or on account of bringing materials, supplies and equipment into or
through the Demised Premises during the course thereof and the obligations of
the Lessee under this Lease shall not thereby be affected in any manner
whatsoever."  Lessor reserves the right to enter upon the Demised Premises at
any time in the event of an emergency and at reasonable hours to exhibit the
Demised Premises to prospective purchasers or others; and to exhibit the Demised
Premises to prospective Lessees and to the display "For Rent" or similar signs
on windows or doors in the Demised Premises during the last One Hundred Twenty
(120) days of the term of this Lease, all without hindrance or molestation by
Lessee.

EMINENT DOMAIN:

13. In the event of any eminent domain or condemnation proceeding or private
sale in lieu thereof in respect to the Premises during the term hereof, the
following provisions shall apply:

    a.   If the whole of the Premises shall be acquired or condemned by eminent
domain for any public or quasipublic use or purpose, then the term of this Lease
shall cease and terminate as of the date possession shall be taken in such
proceeding and all rentals shall be paid up to that date.

    b.   If any part constituting less than the whole of the Premises shall be
acquired or condemned as aforesaid, and in the event that such partial taking or
condemnation shall materially affect the Demised Premises so as to render the
Demised Premises unsuitable for the business of the Lessee, in the reasonable
opinion of Lessor, then the term of this Lease shall cease and terminate as of
the date possession shall be taken by the condemning authority and rent shall be
paid to the date of such termination.


                                          7
<PAGE>


    In the event of a partial taking or condemnation of the Premises which
shall not materially affect the Demised Premises so as to render the Demised
Premises unsuitable for the business of the Lessee, in the reasonable opinion of
the Lessor, this Lease shall continue in full force and effect but with a
proportionate abatement of the Base Rent and Additional Rent based on the
portion, if any, of the Demised Premises taken.  Lessor reserves the right, at
its option, to restore the Building and the Demised Premises to substantially
the same condition as they were prior to such condemnation.  In such event,
Lessor shall give written notice to Lessee within thirty (30) days following the
date possession shall be taken by the condemning authority, of Lessor's
intention to restore.  Upon Lessor's notice of election to restore, Lessor shall
commence restoration and shall restore the Building and the Demised Premises
with reasonable promptness, subject to delays beyond Lessor's control and delays
in the making of condemnation or sale proceeds adjustments by Lessor; and Lessee
shall have no right to terminate this Lease except as herein provided.  Upon
completion of such restoration, the rent shall be adjusted based upon the
portion, if any, of the Demised Premises restored.

    c.   In the event of any condemnation or taking as aforesaid, whether whole
or partial, the Lessee shall not be entitled to any part of the award paid for
such condemnation and Lessor is to receive the full amount of such award, the
Lessee hereby expressly waiving any right to claim to any part thereof.

    d.   Although all damages in the event of any condemnation shall belong to
the Lessor whether such damages are awarded as compensation for diminution in
value of the leasehold or to the fee of the Demised Premises.  Lessee shall have
the right to claim and recover from the condemning authority, but not from
Lessor, such compensation as may be separately awarded or recoverable by Lessee
in Lessee's own right on account of any and all damage to Lessee's business by
reason of the condemnation and for or on account of any cost or loss to which
Lessee might be put in removing Lessee's merchandise, furniture, fixtures,
leasehold improvements and equipment. However, Lessee shall have no claim
against Lessor or make any claim with the condemning authority for the loss of
its leasehold estate, any unexpired term or loss of any possible renewal or
extension of said lease or loss of any possible value of said lease, any
unexpired term, renewal or extension of said Lease.

DAMAGE OR DESTRUCTION:

14. In the event of any damage or destruction to the Premises by fire or other
cause during the term hereof, the following provisions shall apply:


    a.   If the Building is damaged by fire or any other cause to such extent
that the cost of restoration, as reasonably estimated by Lessor, will equal or
exceed thirty percent (30%) of the replacement value of the Building (exclusive
of foundations) just prior to the occurrence of the damage, then Lessor may, no
later than the sixtieth (60th) day following the damage, give Lessee written
notice of Lessor's election to terminate this Lease.

    b.   If the cost of restoration as estimated by Lessor will equal or exceed
fifty percent (50%) of said replacement value of the Building and if the Demised
Premises are not suitable as a 


                                          8
<PAGE>


result of said damage for the purposes for which they are demised hereunder, in
the reasonable opinion of Lessee, then Lessee may, no later than the sixtieth
(60th) day following the damage, give Lessor a written notice of election to
terminate this Lease.

    c.   If the cost of restoration as estimated by Lessor shall amount to less
than thirty percent (30%) of said replacement value of the Building, or if,
despite the cost, Lessor does not elect to terminate this Lease, Lessor shall
restore the Building and the Demised Premises with reasonable promptness,
subject to delays beyond Lessor's control and delays in the making of insurance
adjustments by Lessor; and Lessee shall have no right to terminate this Lease
except as herein provided.  Lessor shall not be responsible for restoring or
repairing leasehold improvements of the Lessee.

    d.   In the event of either of the elections to terminate, this Lease shall
be deemed to terminate on the date of the receipt of the notice of election and
all rentals shall be paid up to that date.  Lessee shall have no claim against
Lessor for the value of any unexpired term of this Lease.

    e.   In any case where damage to the Building shall materially affect the
Demised Premises so as to render them unsuitable in whole or in part for the
purposes for which they are demised hereunder, then, unless such destruction 
was wholly or partially caused by the negligence or breach of the terms of this
Lease by Lessee, its employees, contractors or licensees, a portion of the rent
based upon the amount of the extent to which the Demised Premises are rendered
unsuitable shall be abated until repaired or restored.  If the destruction or
damage was wholly or partially caused by negligence or breach of the terms of
this Lease by Lessee as aforesaid and if Lessor shall elect to rebuild, the 
rent shall not abate and the Lessee shall remain liable for the same. 

CASUALTY INSURANCE:

15. a.   Lessor shall at all times during the term of this Lease, at its 
expense, maintain a policy or policies of insurance with premiums paid in 
advance issued by an insurance company licensed to do business in the State 
of Minnesota insuring the Building against loss or damage by fire, explosion 
or other insurable hazards and contingencies for the full replacement value, 
provided that Lessor shall not be obligated to insure any furniture, equipment,
machinery, goods or supplies not covered by this Lease which Lessee may bring
upon the Demised Premises or any additional improvements which Lessee may
construct or install on the Demised Premises.

    b.   Lessee shall not carry any stock of goods or do anything in or about
the Demised Premises which will in any way impair or invalidate the obligation
of the insurer under any policy of insurance required by this Lease.

    c.   Lessor hereby waives and releases all claims, liabilities and causes
of action against Lessee and its agents, servants and employees for loss or
damage to, or destruction of, the Premises or any portion thereof, including 
the buildings and other improvements situated thereon, resulting from fire,
explosion and other perils included in standard extended coverage insurance,
whether caused by the negligence of any of said persons or otherwise.  
Likewise, Lessee hereby waives and releases all claims, liabilities and causes 
of action against Lessor and its agents, servants and employees for loss or 


                                          9
<PAGE>


damage to, or destruction of, any of the improvements, fixtures, equipment, 
supplies, merchandise and other property whether that of Lessee or of others 
in, upon or about the Premises resulting from fire, explosion or the other 
perils included in standard extended coverage insurance, whether caused by 
the negligence of any of said persons or otherwise. The waiver shall remain 
in force whether or not the Lessee's insurer shall consent thereto.

    d.   In the event that the use of the Demised Premises by Lessee increases
the premium rate for insurance carried by Lessor on the improvements of which
the Demised Premises are a part, Lessee shall pay Lessor, upon demand, the
amount of such premium increase.  If Lessee installs any electrical equipment
that overloads the power lines to the building or its wiring, Lessee shall, at
its own expense, make whatever changes are necessary to comply with the
requirements of the insurance underwriter, insurance rating bureau and
governmental authorities having jurisdiction.

PUBLIC LIABILITY INSURANCE

16. Lessee shall during the term hereof keep in full force and effect at its
expense a policy or policies of public liability insurance with respect to the
Demised Premises and the business of Lessee, on terms with companies approved 
in writing by Lessor, in which both Lessee and Lessor shall be covered by being
named as insured parties under reasonable limits of liability not less than:
$500,000 for injury/death to any one person; $1,000,000 for injury/death to 
more than one person, and $500,000 with respect to damage to property.  Such 
policy or policies shall provide that ten (10) days written notice must be 
given to Lessor prior to cancellation thereof.  Lessee shall furnish evidence
satisfactory to Lessor at the time this Lease is executed that such coverage 
is in full force and effect.

DEFAULT OF LESSEE:

17.  a.   In the event of any failure of Lessee to pay any rental due hereunder
within ten (10) days after the same shall be due, or any failure to perform any
other of the terms, conditions or covenants of this Lease to be observed or
performed by Lessee for more than thirty (30) days after written notice of such
failure shall have been given to Lessee, or if Lessee or an agent of Lessee
shall falsify any report required to be furnished to Lessor pursuant to the
terms of this Lease, or if Lessee or any guarantor of this Lease shall become
bankrupt or insolvent, or file any debtor proceedings or any person shall take
or have against Lessee or any guarantor of this Lease in any court pursuant to
any statute either of the United States or of any state a petition in 
bankruptcy or insolvency or for reorganization or for the appointment of a 
receiver or trustee of all or a portion of Lessee's or any such guarantor's 
property, or if Lessee or any such guarantor makes an assignment for the 
benefit of creditors, or petitions for or enters into an arrangement, or if 
Lessee shall abandon the Demised Premises or suffer this Lease to be taken 
under any writ of execution, then in any such event Lessee shall be in default 
hereunder, and Lessor, in addition to other rights of remedies it may have, 
shall have the immediate right of re-entry and may remove all persons and 
property from the Demised Premises and such property may be removed and stored 
in a public warehouse or elsewhere at the cost of, and for the account of 





                                          10
<PAGE>


Lessee, all without service of notice or resort to legal process and without 
being guilty of trespass, or becoming liable for any loss or damage which may 
be occasioned thereby.

    b.   Should Lessor elect to re-enter the Demised Premises, as herein
provided, or should it take possession of the Demised Premises pursuant to 
legal proceedings or pursuant to any notice provided for by law, it may either
terminate this Lease or it may from time to time, without terminating this
Lease, make such alterations and repairs as may be necessary in order to relet
the Demised Premises, and relet the Demised Premises or any part thereof such
term or terms (which may be for a term extending beyond the term of this Lease)
and at such rental or rentals and upon such other terms and conditions as Lessor
in its sole discretion may deem advisable.  Upon each such subletting all
rentals received by the Lessor from such reletting shall be applied first to 
the payment of any indebtedness other than rent due hereunder from Lessee to 
Lessor; second, to the payment of any costs and expenses of such reletting, 
including brokerage fees and attorney's fees and costs of such alterations 
and repairs; third, to the payment of the rent due and upon payment of future 
rent as the same may become due and payable hereunder.  If such rentals 
received from such reletting during any month be less than that to be paid 
during that month by Lessee hereunder, Lessee, upon demand, shall pay any 
such deficiency to Lessor. No such re-entry or taking possession of the 
Demised Premises by Lessor shall be construed as an election on its part to 
terminate this Lease unless a written notice of such intention be given to 
Lessee or unless the termination thereof be decreed  by a court of competent 
jurisdiction.  Notwithstanding any such reletting without termination, Lessor 
may at any time after such re-entry and reletting elect to terminate this 
Lease for any such breach, in addition to any other remedies it may have, it 
may recover from Lessee all damages it may incur by reason of such breach, 
including the cost of recovering the Demised Premises, reasonable attorney's 
fees, and including the worth at the time of such termination of the excess, 
if any, of the amount of rent and charges equivalent to rent reserved in this 
Lease for the remainder of the stated term over the then reasonable rental 
value of the Demised Premises for the remainder of the stated term, all of 
which amounts shall be immediately due and payable from Lessee to Lessor.

    c.   Lessor may, at its option, instead of exercising any other rights or
remedies available to it in this Lease or otherwise by law, statute or equity,
spend such money as is reasonably necessary to cure any default of Lessee 
herein and the amount so spent, and costs incurred, including attorney's 
fees in curing such default, shall be paid by Lessee, as additional rent, 
upon demand.

    d.   In the event suit shall be brought for recovery of possession of the
Demised Premises, for the recovery of rent or any other amount due under the
provisions of this Lease, or because of the breach of any other covenant herein
contained on the part of Lessee to be kept or performed, and a breach shall be
established, Lessee shall pay to Lessor all expenses incurred therefor,
including a reasonable attorney's fee, together with interest on all such
expenses at the rate of Eighteen and 00/100 percent (18%) per annum from the
date of such breach of the covenants of this Lease.

    e.   Lessee hereby expressly waives any and all rights of redemption
granted by or under any present or future laws in the event of Lessee being



                                          11
<PAGE>




evicted or dispossessed for any cause, or in the event of Lessor obtaining 
possession of the Demised Premises, by reason of the violation by Lessee of 
any of the covenants or conditions of this Lease, or otherwise.  Lessee also 
waives any demand for possession of the Demised Premises, and any demand for 
payment of rent and any notice of intent to re-enter the Demised Premises, or 
of intent to terminate this Lease, other than the notices above provided in 
this Article, and waives any and every other notice or demand prescribed by 
any applicable statutes or laws.

    f.   No remedy herein or elsewhere in this Lease or otherwise by law,
statute or equity, conferred upon or reserved to Lessor or Lessee shall be
exclusive of any other remedy, but shall be cumulative, and may be exercised
from time to time and as often as the occasion may arise.

COVENANTS TO HOLD HARMLESS:

18. Unless the liability for damage or loss is caused by the negligence of
Lessor, its agents or employees, Lessee shall hold harmless Lessor from any
liability for damages to any person or property in or upon the Demised Premises
and the Premises, including the person and the property of Lessee and its
employees and all persons in the Building at its or their invitation or
sufferance, and from all damages resulting from Lessee's failure to perform the
covenants of this Lease.  All property kept, maintained or stored on the Demised
Premises shall be so kept, maintained or stored at the sole risk of Lessee. 
Lessee agrees to pay all sums of money in respect of any labor, service,
materials, supplies or equipment furnished or alleged to have been furnished to
Lessee in or about the Premises, and not furnished on order of Lessor, which may
be secured by any Mechanic's Materialmen's or other lien to be discharged at the
time performance of any obligation secured thereby matures, provided that Lessee
may contest such lien, but if such lien is reduced to final judgment and if such
judgment or process thereon is not stayed, or if stayed and said stay expires,
then and in each such event, Lessee shall forthwith pay and discharge said
judgment.  Lessor shall have the right to post and maintain on the Demised
Premises, notices of non-responsibility under the laws of the State of
Minnesota.

NON-LIABILITY:

19. Subject to the terms and conditions of Article 14 hereof, Lessor shall not
be liable for damage to any property of Lessee or of others located on the
Premises, nor for the loss of or damage to any property of Lessee or of others
by theft or otherwise.  Lessor shall not be liable for any injury or damage to
persons or property resulting from fire, explosion, falling plaster, steam, gas,
electricity, water, rain or snow or leaks from any part of the Premises or from
the pipes, appliances, or plumbing works or from the roof, street or subsurface
or from any other place or by dampness or by any other cause of whatsoever
nature.  Lessor shall not be liable for any such damage caused by other Lessees
or persons in the Premises, occupants of adjacent property, of the buildings, or
the public or caused by operations in construction of any private, public or
quasi-public work.  Lessor shall not be liable for any latent defect in the
Demised Premises.  All property of Lessee kept or stored on the Demised Premises
shall be so kept or stored at the risk of Lessee only and Lessee shall hold
Lessor harmless from any claims arising out of damage to the same, including
subrogation claims by Lessee's insurance carrier.


                                          12

SUBORDINATION:

20. This Lease shall be subordinated to any mortgages that may now exist or
that may hereafter be placed upon the Demised Premises and to any and all
advances made thereunder, and to the interest upon the indebtedness evidenced by
such mortgages, and to all renewals, replacements and extensions thereof.  In
the event of execution by Lessor after the date of this Lease of any such
mortgage, renewal, replacement or extension, Lessee agrees to execute a
subordination agreement with the holder thereof which agreement shall provide
that:

    a.   Such holder shall not disturb the possession and other rights of
Lessee under this Lease so long as Lessee is not in default hereunder,

    b.   In the event of acquisition of title to the Demised Premises by such
holder, such holder shall accept the Lessee as Lessee of the Demised Premises
under the terms and conditions of this Lease and shall perform all the
obligations of Lessor hereunder, and

    c.   The Lessee shall recognize such holder as Lessor hereunder.  Lessee
shall, upon receipt of a request from Lessor therefor, execute and deliver to
Lessor or to any proposed holder of a mortgage or trust deed or to any proposed
purchaser of the Premises, a certificate in recordable form, certifying that
this Lease is in full force and effect, and that there are no offsets against
rent nor defenses to Lessee's performance under this Lease, or setting forth any
such offsets or defenses claimed by Lessee, as the case may be.

ASSIGNMENT OR SUBLETTING:

21. Lessee agrees to use and occupy the Demised Premises throughout the entire
term hereof for the purpose of purposes herein specified and for no other
purposes, in the manner and to substantially the extent now intended, and not to
transfer or assign this Lease or sublet said Demised Premises, or any part
thereof, whether by voluntary act, operation of law, or otherwise, without
obtaining the prior consent of Lessor in each instance.  Lessee shall seek such
consent of Lessor by a written request therefor, setting forth such information
as Lessor may deem necessary.  Lessor agrees not to withhold consent
unreasonably.  Consent by Lessor to any assignment of this Lease or to any
subletting of the Demised Premises shall not be a waiver of Lessor's rights
under this Article as to any subsequent assignment or subletting.  Lessor's
rights to assign this Lease are and shall remain unqualified.  No such
assignment or subleasing shall relieve the Lessee from any of Lessee's
obligations in this Lease contained, nor shall any assignment or sublease or
other transfer of this Lease be effective unless the assignee, sublessee or
transferee shall at the time of such assignment, sublease or transfer, assume in
writing for the benefit of Lessor, its successors or assigns, all of the terms,
covenants and conditions of this Lease thereafter to be performed by Lessee and
shall agree in writing to be bound thereby.  Should Lessee sublease in
accordance with the terms of this Lease, fifty percent (50%) of any increase in
rental received by Lessee over the per square foot rental rate which is being
paid by Lessee shall be forwarded to and retained by Lessor, which increase
shall be in addition to the Base Rent and Additional Rent due Lessor under this
Lease.


                                          13

ATTORNMENT:

22. In the event of a sale or assignment of Lessor's interest, in the Premises,
or the Building in which the Demised Premises are located, or this Lease, or if
the Premises come into custody or possession of a mortgagee or any other party
whether because of a mortgage foreclosure, or otherwise, Lessee shall attorn to
such assignee or other party and recognize such party as Lessor hereunder;
provided, however, Lessee's peaceable possession will not be disturbed so long
as Lessee faithfully performs its obligations under this Lease.  Lessee shall
execute, on demand, any attornment agreement required by any such party to be
executed, containing such provisions and such other provisions as such party may
require.

NOVATION IN THE EVENT OF SALE:

23. In the event of the sale of the Demised Premises, Lessor shall be and
hereby is relieved of all the covenants and obligations created hereby accruing
from and after the date of sale, and such sale shall result automatically in the
purchaser assuming and agreeing to carry out all the covenants and obligations
of Lessor herein.  Notwithstanding the foregoing provisions of this Article,
Lessor, in the event of a sale of the Demised Premises, shall cause to be
included in this agreement of sale and purchase a covenant whereby the purchaser
of the Demised Premises assumes and agrees to carry out all of the covenants and
obligations of Lessor herein.

    The Lessor agrees at any time and from time to time upon not less than ten
(10) days prior written request by the Lessor to execute, acknowledge and
deliver to the Lessor a statement in writing certifying that this Lease is
unmodified and in full force and effect as modified and stating the
modifications, and the dates to which the basic rent and other charges have been
paid in advance, if any, it being intended that any such statement delivered
pursuant to this paragraph may be relied upon by any prospective purchaser of
the fee or mortgagee or assignee of any mortgage upon the fee of the Demised
Premises.

SUCCESSORS AND ASSIGNS:

24. The terms, covenants and conditions hereof shall be binding upon and inure
to the successors and assigns of the parties hereto.

REMOVAL OF FIXTURES:

25. Notwithstanding anything contained in Article 8, 29 or elsewhere in this
Lease, if Lessor requests then Lessee will promptly remove at the sole cost and
expense of Lessee all fixtures, equipment and alterations made by Lessee
simultaneously with vacating the Demised Premises and Lessee will promptly
restore said Demised Premises to the condition that existed immediately prior to
said fixtures, equipment and alterations having been made all at the sole cost
and expense of Lessee.

QUIET ENJOYMENT:

26. Lessor warrants that it has full right to execute and to perform this Lease
and to grant the estate demised, and that Lessee, upon payment of the rents and
other amounts due and the 


                                          14
<PAGE>


performance of all the terms, conditions, covenants and agreements on Lessee's
part to be observed and performed under this Lease, may peaceably and quietly
enjoy the Demised Premises for the business uses permitted hereunder, subject,
nevertheless, to the terms and conditions of this Lease.

RECORDING:

27. Lessee shall not record this Lease without the written consent of Lessor. 
However, upon the request of either party hereto, the other party shall join in
the execution of the Memorandum lease for the purposes of recordation.  Said
Memorandum lease shall describe the parties, the Demised Premises and the term
of the Lease and shall incorporate this Lease by reference.  This Article 27
shall not be construed to limit Lessor's right to file this Lease under Article
22 of this Lease.

OVERDUE PAYMENTS:

28. All monies due under this Lease from Lessee to Lessor shall be due on
demand, unless otherwise specified and if not paid when due, shall result in the
imposition of a service charge for such late payment in the amount of Eighteen
percent (18%) of the amount due.

SURRENDER:

29. On the Expiration Date or upon the termination hereof upon a day other than
the Expiration Date, Lessee shall peaceably surrender the Demise Premises
broom-clean in good order, condition and repair, reasonable wear and tear only
excepted.  On or before the Expiration Date or upon termination of this Lease on
a day other than the Expiration Date, Lessee shall, at its expense, remove all
trade fixtures, personal property and equipment and signs from the Demised
Premises and any property not removed shall be deemed to have been abandoned. 
Any damage caused in the removal of such items shall be repaired by Lessee and
at its expense.  All alterations, additions, improvements and fixtures (other
than trade fixtures) which shall have been made or installed by Lessor or Lessee
upon the Demised Premises and all floor covering so installed shall remain upon
and be surrendered with the Demised Premises as a part thereof, without
disturbance, molestation or injury, and without charge, at the expiration or
termination of this Lease.  If the Demised Premises are not surrendered on the
Expiration Date or the date of termination, Lessee shall indemnify Lessor
against loss or liability, claims, without limitation, made by any succeeding
Lessee founded on such delay.  Lessee shall promptly surrender all keys for the
Demised Premises to Lessor at the place than fixed for payment of rent and shall
inform Lessor of combinations of any locks and safes on the Demised Premises.

HOLDING OVER:

30. In the event of a holding over by Lessee after expiration or termination of
this Lease without the consent in writing of Lessor, Lessee shall be deemed a
lessee at sufferance and shall pay rent for such occupancy at the rate of twice
the last-current aggregate Base and Additional Rent, prorated for the entire
holdover period, plus all attorneys' fees and expenses incurred by Lessor in
enforcing its rights hereunder, plus any other damages occasioned by such
holding over.  


                                          15
<PAGE>


Except as otherwise agreed, any holding over with the written consent of Lessor
shall constitute Lessee with a month-to-month lessee.

ABANDONMENT:

31. In the event Lessee shall remove its fixtures, equipment or machinery or 
shall vacate the Demised Premises or any part thereof prior to the Expiration 
Date of this Lease, or shall discontinue or suspend the operation of its 
business conducted on the Demised Premises for a period of more than thirty 
(30) consecutive days (except during any time when the Demised Premises may be
rendered intenantable by reason of fire or other casualty),then in any such
event Lessee shall be deemed to have abandoned the Demised Premises and Lessee
shall be in default under the terms of this Lease.

CONSENTS BY LESSOR:

32. Whenever provision is made under this Lease for Lessee securing the consent
or approval by Lessor, such consent or approval shall only be in writing.

NOTICES:

33. Any notice required or permitted under this Lease shall be deemed
sufficiently given or secured if sent by registered or certified return 
receipt mail to Lessee at Bio-Metrics Systems, Inc., 9932 West 74th Street, 
Eden Prairie, MN 55344 and to Lessor at the address then fixed for the payment 
of rent as provided in Article 4 of this Lease, and either party may by like 
written notice at any time designate a different address to which notices 
shall subsequently be sent or rent to be paid.

RULES AND REGULATIONS:

34. Lessee shall observe and comply with reasonable rules and regulations as
Lessor may prescribe, on written notice to Lessee for the safety, care and
cleanliness of the Building.

INTENT OF PARTIES:

35. Except as otherwise provided herein, the Lessee covenants and agrees that
if it shall any time fail to pay any such cost or expense, or fail to take out,
pay for, maintain or deliver any of the insurance policies above required, or
fail to make any other payment or perform any other act on its part to be made
or performed as in this Lease provided, then the Lessor may, but shall not be
obligated so to do, and without notice to or demand upon the Lessee and without
waiving or releasing the Lessee from any obligations of the Lessee in this Lease
contained, pay any such cost or expense, effect any such insurance coverage and
pay premiums therefore, and may make any other payment or perform any other act
on the part of the Lessee to be made and performed as in this Lease provided, in
such manner and to such extent as the Lessor may deemed desirable, and in
exercising any such right, to also pay all necessary and incidental costs and
expenses, employ counsel and incur and pay reasonable attorneys' fees.  All sums
so paid by Lessor and all necessary and incidental costs and expenses in
connection with the performance of any such act 


                                          16

by the Lessor, together with interest thereon at the rate of eighteen percent
(18%) per annum from the date of making of such expenditure, by Lessor, shall be
deemed additional rent hereunder, and shall be payable to Lessor on demand. 
Lessee covenants to pay any such sum or sums with interest as aforesaid and the
Lessor shall have the same rights and remedies in the event of the non-payment
thereof by Lessee as in the case of default by Lessee in the payment of the Base
Rent payable under this Lease.

GENERAL:

36. The Lease does not create the relationship of principal and agent or of
partnership or of joint venture or of any association between Lessor and Lessee,
the sole relationship between the parties hereto being that of Lessor and
Lessee.

    No waiver of any default of Lessee hereunder shall be implied from any
omission by Lessor to take any action on account of such default if such default
persists or is repeated, and no express waiver shall affect any default other
than the default specified in the express waiver and that only for the time and
to the extent therein stated.  One or more waivers by Lessor shall not then be
construed as a waiver of subsequent breach of the same covenant, term or
condition.  The consent to or approval by Lessor of any act by Lessee requiring
Lessor's consent or approval shall not waive or render unnecessary Lessor's
consent to or approval of any subsequent similar act by Lessee shall be
construed to be both a covenant and a condition.  No action required or
permitted to be taken by or on behalf of Lessor under the terms or provisions of
this Lease shall be deemed to constitute an eviction or disturbance of Lessee's
possession of the Demised Premises.  All preliminary negotiations are merged
into and incorporated in this Lease.  The laws of the State of            
shall govern the validity, performance and enforcement of this Lease.

    a.   This Lease and the exhibits, if any, attached hereto and forming a
part hereof, constitute the entire agreement between Lessor an Lessee affecting
the Demised Premises and there are no other agreements, either oral or written,
between them other than are herein set forth.  No subsequent alteration,
amendment, change or addition to this Lease shall be binding upon Lessor or
Lessee unless reduced to writing and executed in the same form and manner in
which this Lease is executed.

    b.   If any agreement, covenant or condition of this Lease or the
application thereof to any person or circumstances shall, to any extent, be
invalid or unenforceable, the remainder of this Lease, or the application of
such agreement, covenant or condition to persons or circumstances other than
those as to which it is held invalid or unenforceable, shall not be affected
thereby and each agreement, covenant or condition of this Lease shall be valid
and be enforced to the fullest extent permitted by law.

HAZARDOUS MATERIAL:

37. a.   The Premises hereby leased shall be used by and/or at the sufferance
of Lessee only for the purpose set forth in Article 11 above and for no other
purposes.  Lessee shall not use or permit the use of the Premises in any manner
that will tend to create waster or a nuisance, or 


                                          17

will tend to unreasonably disturb other Lessees in the Building or the Project. 
Lessee, its employees and all persons visiting or doing business with Lessee in
the Premises shall be bound by and shall observe the Building Rules and
Regulations attached to this Lease as Exhibit "C", and such further and other
reasonable rules and regulations made hereafter by Lessor relating to the
Premises, the Building or the Project of which notice in writing shall be given
to the Lessee, and all such rules and regulations shall be deemed to be
incorporated into and form a part of this Lease.

    b.   Lessee covenants throughout the Lease Term, at Lessee's sole cost and
expense, promptly to  comply with all laws and ordinances and the orders, rules
and regulations and requirements of all federal, state and municipal governments
and appropriate departments, commissions, boards, and officers thereof, and the
orders, rules and regulations of the Board of Fire Underwriters where the
Premises are situated, or any other body now or hereafter well as extraordinary,
and whether or not the same require structural repairs or alterations, which may
be applicable to the Premises, or the use or manner of use of the Premises. 
Lessee will likewise observe and comply with the requirements of all policies of
public liability, fire and all other policies of insurance at any time in force
with respect to the buildings and improvements on the Premises and the equipment
thereof.

    c.   In the event any Hazardous Material (hereinafter defined) is brought
or caused to be brought into or onto the Premises, the Building or the Project
by Lessee, Lessee shall handle any such material in compliance with all
applicable federal, state and/or local regulations.  For purposes of this
Article, "Hazardous Material" means and includes any hazardous, toxic or
dangerous waste, substance or material defined as such in (or for purposes of)
the Comprehensive Environmental Response, Compensation, and Liability Act, any
so-called "Superfund" or "Superlien" law, or any federal, state or local
statute, law, ordinance, code, rule, regulation, order decree regulating,
relating to, or imposing liability or standards of conduct concerning, any
hazardous, toxic or dangerous waste, substance or material, as now or at any
time hereafter in effect.  Lessee shall submit to Lessor on an annual basis
copies of its approved hazardous materials communication plan, OSHA monitoring
plan, and permits required by the Resource Recovery and Conservation Act of
1976, if Lessee is required to prepare, file or obtain any such plans or
permits.  Lessee will indemnify and hold harmless Lessor from any losses,
liabilities, damages, costs or expenses (including reasonable attorneys' fees)
which Lessor may suffer or incur as a result of Lessee's introduction into or
onto the Premises of any Hazardous Material.  This Article shall survive the
expiration or sooner termination of this Lease.

groundwater found to contain such hazardous or deleterious materials shall be

through the roof of the Demised Premises or elsewhere in the building created by
or the result of removal of Lessee's fixtures shall be repaired by a contractor
approved by the Lessor.

available for Lease as described in Article 46 of the Addendum to Lease, dated
November 18, 1991.

    8.   OPTION TO EXTEND LEASE TERM:

    b.   Should Tenant exercise its Option, Base Rent shall be as follows:

              Period                             Monthly Base Rent
              ------                             -----------------

         January 1, 2000 through and

other renewal period shall be renegotiated by Landlord and Tenant.

    c.   Tenant shall exercise said Option by giving written notice to Landlord

shall then have ten (10) business days within which to revoke in writing its
exercise of the Option.

    d.   It is understood and agreed that this Option is personal to Bio-Metric
Systems, Incorporated and is not transferrable.  In the event of any assignment
or subleasing of any or all of the Demised Premises, said Option shall be null
and void.

    9.   The terms and conditions of this Agreement to Amend and Extend Lease
are contingent upon full execution of a termination agreement with Challenge

                                   SECTION 2.

                                     PURPOSE

     The purpose of the Plan is to promote the success of the Company by
facilitating the employment and retention of competent personnel and by
furnishing incentive to employees upon whose efforts the success of the Company
will depend to a large degree.

     It is the intention of the Company to carry out the Plan through the
granting of stock options which will qualify as "Incentive Stock Options" under
the provisions of Section 422A of the Internal Revenue Code.  Adoption of this
Plan shall be and is expressly subject to the condition of approval by the
shareholders of the Company within twelve (12) months before or after the
adoption of such Plan by the Board of Directors.

                                   SECTION 3.

                             EFFECTIVE DATE OF PLAN

                                 ADMINISTRATION

     The Plan shall be administered by the Board of Directors of the Company
(the "Board") or, to the extent empowered by the Board, by the Stock Option
Committee as defined in Section 1 (f) of this Plan.  The Board shall have all of
the powers vested in it under the provisions of the Plan, including but not
limited to exclusive authority (where applicable and within the limitations
described herein) to determine the employees to whom, and the time or times at
which, options shall be granted, the number of shares subject to each option and
the option price and terms and conditions of each option.  Without limiting the
generality of the foregoing, the Board may, in its sole discretion, determine
the number of shares subject to an option in proportion to an employee's
compensation paid by the Company.

     The Board, or the Committee if so empowered by the Board, shall have full
power and authority to administer and interpret the Plan, to make and amend
rules, regulations and guidelines for administering the Plan, to prescribe the
form and conditions of the respective stock option agreements (which may vary
from optionee to Optionee) evidencing each option and to make all other
determinations necessary or advisable for the administration of the Plan.  The
Board's interpretation of the Plan, or the Committee's interpretation if so
empowered by the Board, and all actions taken and determinations made by it
pursuant to the power vested hereunder, shall be conclusive and binding on all
parties concerned.  No member of the Board or the Committee shall be liable for
any action taken or determination made in good faith in connection with the
administration of the Plan.


                                       -2-
<PAGE>


     In the event the Board appoints a Committee as provided hereunder, any
action of the Committee with respect to the administration of the Plan shall be
taken pursuant to a ma3ority vote of the Committee members or pursuant to the
written resolution of all Committee members.

                                   SECTION 5.

                                  PARTICIPANTS

     The Board, or the Committee if so empowered by the Board, shall from time
to time, at its discretion and without approval of the shareholders, designate
those employees of the Company to whom stock options shall be granted.
Directors of the Company who are otherwise engaged as employees of the Company
may be designated as participants.  The Board, or the Committee if so empowered
by the Board, may grant additional options to some or all participants then
holding options or may grant options solely or partially to new participants.
In designating participants, the Board, or the Committee, shall also determine
the number of shares to be optioned to each such participant.

                                   SECTION 6.

                                      STOCK

     The Stock to be optioned under this Plan shall consist of authorized but
unissued shares of voting common stock.  Two Hundred thousand (200,000) shares
of voting common stock shall be reserved and available for options under the
Plan; provided, however, that the total number of shares of Common Stock
reserved for options under this Plan shall be subject to adjustment as provided
in Section 11 of the Plan.  In the event that any outstanding option under the
Plan for any reason expires or is terminated prior 'to the exercise thereof, the
shares of Common Stock allocable to the unexercised portion of such option shall
continue to be reserved for options under the Plan and may be optioned
hereunder.

                                   SECTION 7.

                             LIMITATIONS ON OPTIONS

     Effective for options granted after December 31, 1986, the aggregate fair
market value (determined as of the time an option is granted) of the stock with
respect to which incentive stock options are exercisable for the first time by
an optionee during any calendar year under this Plan and any other plans of the
Company under Section 422A of the Internal Revenue Code, shall not exceed One
Hundred Thousand Dollars ($100,000).

                                   SECTION 8.

                                DURATION OF PLAN

                                   SECTION 9.

                                     PAYMENT

                                   SECTION 10.

                         TERMS AND CONDITIONS OF OPTIONS

     Each option granted pursuant to the Plan shall be evidenced by a written
stock option agreement (the "Option Agreement").  The Option Agreement shall be
in such form as may be approved by the Board, or the Committee if empowered by
the Board, from time to time and may vary from Optionee to Optionee; provided,
however, that each optionee and each Option Agreement shall comply with and be
subject to the following terms and conditions:

     (a)   NUMBER OF SHARES AND OPTION PRICE.  The Option Agreement shall state
     the total number of shares covered by the Option.  The option price per
     share shall not be less than one hundred percent (100%) of the fair market
     value of the Common Stock per share on the date the Board or the Committee
     grants the option; provided, however, that if an optionee owns stock
     possessing more than ten percent (10%) of the total combined voting power
     of all classes of stock of the Company or of its parent or any subsidiary,
     the option price per share of an option granted to such Optionee shall not
     be less than one hundred ten percent (110%) of the fair market value of the
     Common Stock per share on the date of the grant of the option.  For
     purposes hereof, "fair market value" of the Common Stock per share shall be
     determined by the Board, or the Committee if so empowered by the Board, in
     its sole discretion by applying principles of valuation with respect to all
     such options.  The Board shall have full authority and discretion in
     establishing the option price and shall be fully protected in so doing.  If
     such stock is publicly traded as of the date the option is granted, the
     "fair market value" of the Common Stock shall be the mean between the "bid"
     and "asked" prices quoted by a recognized specialist in the Common Stock of
     the Company on the date the option is granted, or if there are no quoted
     "bid" and "asked" prices on such date, on the next preceding date for which
     there are such quotes; provided that if such stock is then listed upon an
     established stock exchange or exchanges, such "fair market value" shall be
     the highest closing price of such stock on such stock exchange or exchanges
     on the date the option is granted or, if no sale of such stock shall have
     occurred on any stock exchange on that date, on the next preceding day on
     which there was a sale of stock.

     (b)   TERM AND EXERCISABILITY OF OPTION.  The term during which any option
     granted under the Plan may be exercised shall be established in each case
     by the Board, or the Committee if so empowered by the Board, but in no
     event shall any option be exercisable during a term of more than five (5)
     years after the date on which it is granted.  The stock option agreement
     shall state when the option becomes exercisable and shall also state the
     maximum term during which the option may be exercised.  In the event an
     option is exercisable immediately, the manner of exercise of the option in
     the event it is not


                                       -4-
<PAGE>


     exercised in full immediately shall be specified in the stock option
     agreement.  The Board, or the Committee if so empowered by the Board, may
     accelerate the exercise date of any option granted hereunder which is not
     immediately exercisable as of the date of grant.

     (c)   TRANSFER OF PPTION.  No option shall be transferable, in whole or in
     part, by the Optionee other than by will or by the laws of descent and
     distribution and, during the Optionee's lifetime, the option may be
     exercised only by the Optionee.  If the Optionee shall attempt any transfer
     of any option granted under the Plan during his lifetime, such transfer
     shall be void and the option, to the extent not fully exercised, shall
     terminate.

     (d)   OTHER PROVISIONS.  The Option Agreement authorized under this Section
     10 shall contain such other provisions as the Board, or the Committee if so
     empowered by the Board, shall deem advisable, including, without
     limitation, a provision granting the Company a repurchase right in the
     event the optionee either (i) transfers or attempts to transfer stock
     acquired pursuant to t e exercise of an option to an individual other than
     a member of optionee's family or another employee of the Company or (ii)
     terminates employment with the Company.  Any such Option Agreement shall
     also contain such limitations and restrictions upon the exercise of the
     option as shall be necessary to ensure that such option will be considered
     an "Incentive Stock Option" as defined in Section 422A of the Internal
     Revenue Code or to conform to any change therein.

     (e)   HOLDING PERIOD.  The disposition of any shares of Common Stock
     acquired by an optionee pursuant to the exercise of an option described
     above shall not be eligible for the favorable taxation treatment of Section
     421(a) of the Internal Revenue Code unless any shares so acquired are held
     by the Optionee for at least two (2) years from the date of the granting of
     the option under which the shares were acquired and at least one year after
     the acquisition of such shares pursuant to the exercise of such option.  In
     the event of an optionee's death, such holding period shall not be
     applicable pursuant to Section 421(c)(1) of the Internal Revenue Code.

                                   SECTION 11.

                                RECAPITALIZATION

     In the event of an increase or decrease in the number of shares of Common
Stock resulting from a subdivision or consolidation of shares or the payment of
a stock dividend or any other increase or decrease in the number of shares of
Common Stock effected without receipt of consideration by the Company, the
number of shares of Common Stock covered by each outstanding option and the
price per share thereof shall be equitably adjusted by the Board of Directors to
reflect such change.  Additional shares which may be credited pursuant to such
adjustment shall be subject to the same restrictions as are applicable to the
shares with respect to which the adjustment relates.

     Unless otherwise provided in the option agreement, in the event of the sale
by the Company of substantially all of its assets and the consequent
discontinuance of its business. or in the event of a merger, exchange,
consolidation or liquidation of the Company, the Board of


                                       -5-
<PAGE>


Directors may in connection with the Board's adoption of the plan for sale,
merger, exchange, consolidation or liquidation, provide for the complete
termination of this Plan and cancellation of outstanding options not exercised
prior to a date (prior to the effectiveness of such sale, merger, exchange,
consolidation or liquidation) specified by the Board or for the continuance of
the Plan only with respect to the exercise of options which, under the terms of
Paragraph (b) of Section 10, were exercisable as of the date of adoption by the
Board of such plan for sale, merger, exchange, consolidation or liquidation;
provided, however, that in any event optionees holding options exercisable as of
the date of the Board's adoption of the plan for sale, merger, exchange,
consolidation or liquidation shall be given either (i) a reasonable time within
which to exercise such exercisable portions of their options prior to the
effectiveness of such sale, merger, exchange, consolidation or liquidation, or
(ii) the right to exercise their respective options as to an equivalent number
of shares of stock of the corporation succeeding the Company by reason of such
sale, merger, exchange, consolidation or liquidation.  The grant of an option
pursuant to the Plan shall not limit in any way the right or power of the
Company to make adjustments, reclassifications, reorganizations or changes of
its capital or business structure or to merge, exchange or consolidate or to
dissolve, liquidate, sell or transfer all or any part of its business or assets.

                                   SECTION 12.

                               INVESTMENT PURPOSE

No shares of Common Stock shall be issued pursuant to the Plan unless and until
there has been compliance, in the opinion of Company's counsel, with all
applicable legal requirements, including without limitation, those relating to
securities laws and stock exchange listing requirements.  As a condition to the
issuance of Common Stock to Optionee, the Board may require Optionee to (a)
represent that the shares of Common Stock are being acquired for investment and
not resale and to make such other representations as the Board shall deem
necessary or appropriate to qualify the issuance of the shares as exempt from
the Securities Act of 1933 and any other applicable securities laws, and (b)

of the Option Stock.  If this option has been granted prior to approval of the
Plan by the Company's shareholders, this option shall not be exercisable until
such approval is obtained.  If this option terminates for any reason, including

     5.    MANNER OF EXERCISE OF OPTION.  This option is to be exercised by the
Optionee (or by the Optionee's successor or successors) by giving written notice
to the Company of an election to exercise such option.  Such notice shall
specify the number of shares to be purchased hereunder and shall be delivered to
the Company at its principal place of business.  An option shall be considered

provides.

     8.    WITHHOLDING TAXES ON DISQUALIFYING DISPOSITION BY OPTIONEE.  In the

disqualifying disposition or upon independently learning of such a disposition,
the Company shall withhold from whatever payments are due Optionee appropriate
state and federal income taxes as required by law.  In the event the Company is
unable to withhold such taxes, for whatever reason, optionee hereby agrees to
pay to the Company an amount equal to the amount the Company would otherwise be
required to withhold under state or federal law.

     9.    INVESTMENT PURPOSE.  The Company may require as a condition to the
grant and exercise of this option that any stock acquired pursuant to this

<PAGE>


investment if, in the opinion of counsel for the Company, such is required or
deemed advisable under securities laws or any other applicable law, regulation
or rule of any government or governmental agency.  In this regard, if requested
by the Company, the Optionee, prior to the acquisition of any shares pursuant to

months after the date of such termination of employment and (ii) this option's
originally stated expiration date.

     11.   TERMINATION OF EMPLOYMENT DUE TO DISABILITY.  If the Optionee ceases
to be an employee of the Company because such Optionee is disabled (as that term
is defined in Section 105(d)(4) of the Internal Revenue Code), this option shall

employment with the Company as provided in Paragraph 10, or (iii) within six
months after the termination of employment with the Company as provided in
Paragraph 11, this option shall terminate (notwithstanding Paragraph 3 of this
Agreement) on the earlier of (i) twelve months after the date of death and (ii)
this option's originally stated expiration date.  In such period following the
Optionee's death, this option shall be exercisable only by the optionee's legal
representative or by the person or persons to whom the optionee's rights under
this option shall pass by the Optionee's will or by the laws of descent and
distribution.

     13.   RIGHT OF REPURCHASE OF OPTION STOCK BY COMPANY.  In the event the
Optionee exercises this option and purchases Option Stock, the Company shall
have the right to repurchase all, but not part, of such Option Stock if the
Optionee (i) transfers or attempts to transfer any such Option Stock to any
person or entity, other than to a member of the optionee's family or another
employee of the Company, or (ii) terminates employment with the Company for any
reason other than death or disability as hereinabove defined, If the Optionee
transfers Option Stock to a family member or another employee of the Company,
the repurchase rights of the Company herein provided shall continue to apply to
all such transferred stock as if the Optionee continued to hold such stock.  The
Company s a exercise its repurchase rights by giving written notice to the
record holder of the Option Stock within six (6) months after (i) with respect
to an unpermitted transfer of the Option Stock, the date when the Company is
given written notice to transfer record ownership of the affected Option Stock,
or (ii) with respect to termination of employment, the date of termination of
employment.  The Company shall pay to the record holder of the Option Stock so
repurchased the Purchase Price, hereinafter defined, in cash, within 30 days
after exercise of its repurchase right.


                                      -10-
<PAGE>


     The Purchase Price for the Option Stock shall be determined as follows:

           (a) If the  Plan is in effect on the date of exercise of the
     Company's repurchase right, (or, if on such date there is any similar stock
     option plan of the Company which, under federal income tax law, requires a
     determination of fair market value of stock similar to the Option Stock to
     receive favorable tax treatment), the Purchase Price shall be the value
     last determined by the Board for the issuance of an option pursuant to the
     Plan (provided, however, that if such option were granted to an Optionee
     holding stock possessing more than 10% of the Company's voting power, as
     defined in the Plan, the Purchase Price shall be 91% of such amount) if
     such determination was made within two years of the exercise of the
     repurchase right.

           (b) If the Purchase Price is not determinable in accordance with the
     preceding subparagraph, it shall be as determined by mutual agreement of
     the Company and the Optionee or, in the event that a mutually agreeable
     value is not determined within 30 days after the Company exercises its
     repurchase option, then either the Company or the Optionee may require that
     the Purchase Price be determined by appraisal.  The appraisal shall be
     conducted by a single appraiser if the optionee and the Company are able to
     agree upon a single appraiser within 10 days after a demand for appraisal
     is made.  Otherwise, the Company and the optionee shall each designate an
     appraiser, and the appraisers so designated shall appoint a third appraiser
     or if they are not able to agree upon a third person, the third appraiser
     shall be chosen by the chief judge of the District Court of Hennepin
     County, Minnesota).  Upon the appointment of an appraiser or appraisers,
     the Purchase Price shall be the fair market value of the Option Stock as
     determined by the single appraiser, or by a majority of the three
     appraisers, which appraisers shall be required to issue a written report
     within 45 days after their appointment (either of the single appraiser or
     of the third of three appraisers).  The Purchase Price as so determined
     shall be binding upon the Company and the optionee.

     14.   MISCELLANEOUS.  This Agreement shall bind and inure to the benefit of
the Company and its successors and assigns and the Optionee and any successor or
successors of the Optionee permitted by Paragraph 4 above.  It is intended that
this option will qualify as an Incentive Stock option under the provisions of
Section 422A of the Internal Revenue Code; provided, however, that Optionee
hereby agrees to personally bear whatever income tax and other burden which may
arise if this option does not so qualify and hereby releases the Company from
and against any claim Optionee might otherwise have in the event this option is
not so qualified.

allocable to the unexercised portion of such option shall continue to be
reserved for options under the Plan and may be optioned hereunder.

this Plan and any other plans of the Company under Section 422 of the Internal
Revenue Code, shall not exceed $100,000.

such stock's then Fair Market Value, or such other form of payment as may be
authorized by the Company.  The Company may, in its sole discretion, limit the
form of the payment available to the Optionee and may exercise such discretion
at any time prior to the termination of the option granted to Optionee or upon
any exercise of the option by the Optionee.  With respect to payment in the form
of Common Stock of the Company, the Administrator may require advance approval
or adopt such rules as it deems necessary to assure compliance with Rule
16(b)-3, or any successor provision, as then in effect, of the General Rules and
Regulations under the Securities Exchange Act of 1934, if applicable.

                                     SECTION 10.
                           TERMS AND CONDITIONS OF OPTIONS

    Each option granted pursuant to the Plan shall be evidenced by a written
stock option agreement (the "Option Agreement").  The Option Agreement shall be
in such form as may be


                                         -3-
<PAGE>

approved by the Board, or the Committee if empowered by the Board, from time to
time and may vary from Optionee to Optionee; provided, however, that each
Optionee and each Option Agreement shall comply with and be subject to the
following terms and conditions:

    (a)  NUMBER OF SHARES AND OPTION PRICE.  The Option Agreement shall state
         the total number of shares covered by the Option.  The option price
         per share shall not be less than 100% of the fair market value of the
         Common Stock per share on the date the Board or the Committee grants
         the option; provided, however that if an Optionee owns stock
         possessing more than 10% of the total combined voting power of all
         classes of stock of the Company or of its parent or any subsidiary,
         the option price per share of an option granted to such Optionee shall
         not be less than 110% of the fair market value of the Common Stock per
         share on the date of the grant of the option.  For purposes thereof,
         "fair market value" of the Common Stock per share shall be determined
         by the Board, or the Committee if so empowered by the Board, in its
         sole discretion by applying principles of valuation with respect to
         all such options.  The Board shall have full authority and discretion
         in establishing the option price and shall be fully protected in so
         doing.  If such stock is publicly traded as of the date the option is
         granted, the "fair market value" of the Common Stock shall be the mean
         between the "bid" and "asked" prices quoted by a recognized specialist
         in the Common Stock of the Company on the date the option is granted,
         or if there are no quoted "bid" and "asked" prices on such date, on
         the next preceding date for which there are such quotes; provided that
         if such stock is then listed upon an established stock exchange or
         exchanges, such "fair market value" shall be the highest closing price
         of such stock on such stock exchange or exchanges on the date the
         option is granted or, if no sale of such stock shall have occurred on
         any stock exchange on that date, on the next preceding day on which
         there was a sale of stock.

    (b)  TERM AND EXERCISABILITY OF OPTION.  The term during which any option
         granted under the Plan may be exercised shall be established in each
         case by the Board, or the Committee if so empowered by the Board, but
         in no event shall any option be exercisable during a term of more than
         10 years after the date on which it is granted.  The Option Agreement
         shall state when the option becomes exercisable and shall also state
         the maximum term during which the option may be exercised.  In the
         event an option is exercisable immediately, the manner of exercise of
         the option in the event it is not exercised in full immediately shall
         be specified in the Option Agreement.  The Board, or the Committee if
         so empowered by the Board, may accelerate the exercise date of any
         option granted hereunder which is not immediately exercisable as of
         the date of grant.

    (c)  TRANSFER OF OPTION.  No option shall be transferable, in whole or in
         part, by the Optionee other than by will or by the laws of descent and
         distribution and, during the Optionee's lifetime, the option may be
         exercised only by the Optionee.  If the Optionee shall attempt any
         transfer of any option granted under the Plan during


                                         -4-
<PAGE>

         his lifetime, such transfer shall be void and the option, to the
         extent not fully exercised, shall terminate.

    (d)  OTHER PROVISIONS.  The Option Agreement authorized under this Section
         10 shall contain such other provisions as the Board, or the Committee
         if so empowered by the Board, shall deem advisable.  Any such Option
         Agreement shall also contain such limitations and restrictions upon
         the exercise of the option as shall be necessary to ensure that such
         option will be considered an "Incentive Stock Option" as defined in
         Section 422 of the Internal Revenue Code or to conform to any change
         therein.

    (e)  HOLDING PERIOD.  The disposition of any shares of Common Stock
         acquired by an Optionee pursuant to the exercise of an option
         described above shall not be eligible for the favorable taxation
         treatment of Section 421(a) of the Internal Revenue Code unless any
         shares so acquired are held by the Optionee for at least 2 years from
         the date of the granting of the option under which the shares were
         acquired and at least one year after the acquisition of such shares
         pursuant to the exercise of such option.  In the event of an
         Optionee's death, such holding period shall not be applicable pursuant
         to Section 421(c)(1) of the Internal Revenue Code.

    (e)  The disposition of any shares of Common Stock acquired by on Optionee
         pursuant to the exercise of an option describe above shall not be
         eligible for the favorable taxation treatment of Section 421(a) of the
         Internal Revenue Code unless any shares so acquired are held by the
         Optionee for at least 2 years from the date of the granting of the
         option under which the shares were acquired and at least one year
         after the acquisition of such shares pursuant to the exercise of such
         option.  In the event of an Optionee's death, such holding period
         shall not be applicable pursuant to Section 421(c)(1) of the Internal
         Revenue Code.

                                     SECTION 11.
                                   RECAPITALIZATION

    In the event of an increase or decrease in the number of shares of Common
Stock resulting from a subdivision or consolidation of shares or the payment of
a stock dividend or any other increase or decrease in the number of shares of
Common Stock effected without receipt of consideration by the Company, the
number of shares of Common Stock covered by each outstanding option and the
price per share thereof shall be equitably adjusted by the Board of Directors to
reflect such change.  Additional shares which may be credited pursuant to such
adjustment shall be subject to the same restrictions as are applicable to the
shares with respect to which the adjustment relates.

Unless otherwise provided in the Option Agreement, in the event of the sale by
the Company of substantially all of its assets and the consequent discontinuance
of its business, or in the event of a merger, exchange, consolidation or
liquidation of the company, the Board of Directors may in connection with the
Board's adoption of the plan for sale, merger, exchange, consolidation or


                                         -5-
<PAGE>

liquidation, provide for the complete termination of this Plan and cancellation
of outstanding options not exercised prior to a date (prior to the effectiveness
of such sale, merger, exchange, consolidation or liquidation) specified by the
Board or for the continuance of the Plan only with respect to the exercise of
options which, under the terms of Paragraph (b) of Section 10, were exercisable
as of the date of adoption by the Board of such plan for sale, merger, exchange,
consolidation or liquidation; provided, however, that in any event Optionees
holding options exercisable as of the date of the Board's adoption of the plan
for sale, merger, exchange, consolidation or liquidation shall be given either
(i) a reasonable time within which to exercise such exercisable portions of
their options prior to the effectiveness of such sale, merger, exchange,
consolidation or liquidation , or (ii) the right to exercise their respective
options as to an equivalent number of shares of stock of the corporation
succeeding the Company by reason of such sale, merger, exchange, consolidation
or liquidation.  The grant of an option pursuant to the Plan shall not limit in
any way the right or  power of the Company to make adjustments,
reclassifications, reorganizations or changes of its capital or business
structure or to merge, exchange or consolidate or to dissolve, liquidate, sell
or transfer all of any part of its business or assets.

                                     SECTION 12.
                                  INVESTMENT PURPOSE

    No shares of Common Stock shall be issued pursuant to the Plan unless and
until there has been compliance, in the opinion of Company's counsel, with all
applicable legal requirements, including without limitation, those relating to
securities laws and stock exchange listing requirements.  As a condition to the
issuance of Common Stock to Optionee, the Company may require Optionee to (a)
represent that the shares of Common Stock are being acquired for investment and
not resale and to make such other representations as the Board shall deem
necessary or appropriate to qualify the issuance of the shares as exempt from
the Securities Act of 1933 and any other applicable securities laws, and (b)
represent that Optionee shall not dispose of the shares of Common Stock in
violation of the Securities Act of 1933 or any other applicable securities laws.
Company reserves the right to place a legend on any stock certificate issued
upon exercise of an option granted pursuant to the Plan to assure compliance
with this Section 12.

                                     SECTION 13.
                                RIGHTS AS A SHAREHOLDER

    As Optionee (or the Optionee's successor or successors) shall have no
rights as a shareholder with respect to any shares covered by an option until
the date of the issuance of a stock certificate evidencing such shares.  No
adjustment shall be made for dividends (ordinary or extraordinary, whether in
cash, securities or other property), distributions or other rights for which the
record date is prior to the date such stock certificate is actually issued
(except as otherwise provided in Section 11 of the Plan).

                                     SECTION 14.
                                AMENDMENT OF THE PLAN

    The Board of Directors of the Company may from time to time, insofar as
permitted by law, suspend or discontinue the Plan or revise or amend it in any
respect; provided, however, that no such revision or amendment, except as is
authorized in Section 9 and 11, shall impair terms and conditions of any option
which is outstanding on the date of such revision or amendment to the material
detriment of the Optionee without the consent of the Optionee.  Notwithstanding
the foregoing, no such revision or amendment shall (i) materially increase the
number of shares subject to the Plan except as provided in Section 11 hereof;
(ii) change the designation of the class of employees eligible to receive
options, (iii) decrease the price at which options may be granted, or (iv)
materially increase the benefits accruing to Optionees under the plan, unless
such revision or amendment is approved by the shareholders of the Company.
Furthermore, the Plan may not, without the approval of the shareholders, be
amended in any manner that will cause options to fail to meet the requirements
of "Incentive Stock Options" as defined in Section 422 of the Internal Revenue
Code.

                                      SECTION 15
                           NO OBLIGATION TO EXERCISE OPTION

    The granting of an option shall impose no obligation upon the Optionee to
exercise such option.  Further, the granting of an option hereunder shall not
impose upon the Company or any subsidiary any obligation to retain the Optionee
in its employ for any period.

                        1997 INCENTIVE STOCK OPTION AGREEMENT

    THIS AGREEMENT, made this _____ day of ____________, 1997, by and between
BSI CORPORATION, a Minnesota corporation (the "Company"), and _______________,
(the "Optionee");

                                     WITNESSETH:

    WHEREAS, the Optionee on the date hereof is an employee of the Company; and

    WHEREAS, the Company's Board of Directors has adopted an incentive stock
option plan known as the "BSI Corporation 1997 Incentive Stock Option Plan"
(hereinafter referred to as the "Plan"); and

    WHEREAS, the Company desires to grant the Optionee and option to purchase
shares of its voting common stock ("Common Stock");

    NOW THEREFORE, in consideration of the premises and the mutual covenants
herein contained, the Company and the Optionee hereby agree as follows:

    1.   GRANT OF OPTION.  The Company hereby grants to the Optionee, on the

    3.   TERM OF OPTION.  The term during which this option may be exercised
expires five years after the date of this Agreement unless terminated earlier

    4.   PERSONAL EXERCISE BY OPTIONEE.  This option shall, during the lifetime
of the Optionee, be exercisable only by said Optionee and shall not be
transferable by the Optionee, in whole or in part, other than by will or by the
laws of descent and distribution.

    5.   MANNER OF EXERCISE OF OPTION.  This option is to be exercised by the
Optionee (or by the Optionee's successor or successors) by giving written notice
to the Company of an election to exercise such option.  Such notice shall
specify the number of shares to be purchased hereunder and shall be delivered to
the Company at its principal place of business.  An option shall be considered
exercised at the time the Company receives such notice.  Upon receipt of such
notice and subject to the provisions of Paragraph 9 below, the Company shall,
within a reasonable time, and upon payment of the full purchase price for the
shares to be purchased, deliver to the Optionee certificates for the shares so
purchased.  Payment for shares of Option Stock may be made in the form of cash,
personal check, certified check, Common Stock of the Company valued at such
stock's then fair market value, or such other form of payment as may be
authorized by the Company of the Plan.  All requisite original issue or transfer
documentary stamp taxes shall be paid by the Company.

    6.   RIGHTS AS A SHAREHOLDER.  The Optionee or a transferee of this option
shall have no rights as a shareholder with respect to any shares covered by this
option until the date of the issuance of a stock certificate for the Option
Stock.  No adjustment shall be made for dividends (ordinary or extraordinary,

for which the record date is prior to the date such stock certificate is issued,
except as provided in Section 11 of the Plan.

    7.   STOCK OPTION PLAN.  The option evidenced by this Agreement is granted
pursuant to the Plan, a copy of which Plan is attached hereto or has been made
available to the Optionee and is hereby made a part of this Agreement.  This
Agreement is subject to and in all respects limited and conditioned as provided
in the Plan.  This Plan governs this option and the Optionee, and in the event
of any question as to the construction of this Agreement or of a conflict
between the Plan and this Agreement, the Plan shall govern, except as the Plan
otherwise provides.

    8.   WITHHOLDING TAXES ON DISQUALIFYING DISPOSITION BY OPTIONEE.  In the
event of a disqualifying disposition of Option Stock by Optionee, Optionee
hereby agrees to inform the Company of such disposition.  Upon notice of a
disqualifying disposition or upon independently learning of such a disposition,
the Company shall withhold from whatever payments are due Optionee appropriate
state and federal income taxes as required by law.  In the event the Company is
unable to withhold such taxes, for whatever reason, Optionee hereby agrees to
pay to the Company an amount equal to the amount the Company would otherwise be
required to withhold under state and federal law.


                                         -9-

    9.   INVESTMENT PURPOSE.  The Company may require as a condition to the
grant and exercise of this option that any stock acquired pursuant to this
option be acquired for only investment if, in the opinion of counsel for the
Company, such is required or deemed advisable under securities laws or any other
applicable law, regulation or rule of any government or governmental agency.  In
this regard, if requested by the Company, the Optionee, prior to the acquisition
of any shares pursuant to this option, shall execute an investment letter to the
effect that the Optionee is acquiring share pursuant to this option for
investment purposes only and not with the intention of making any distribution
of such shares.

    10.  TERMINATION OF EMPLOYMENT.  If the Optionee ceases to be an employee
of the Company for any reason (including termination of employment as a result
of the reorganization, sale or liquidation by the Company) other than because of
death or disability (as described below) this option shall terminate
(notwithstanding Paragraph 3 of this Agreement) on the earlier of (i) three
months after the date of such termination of employment and (ii) this option's
originally stated expiration date.  Optionee acknowledges that Optionee is and
shall remain an employee at-will; this option is not intended to and shall not
affect the at-will nature of the employment relationship.

    11.  TERMINATION OF EMPLOYMENT DUE TO DISABILITY.  If the Optionee ceases
to be an employee of the Company because such Optionee is totally disabled, this
option shall terminate (notwithstanding Paragraph 3 of this Agreement) on the
earlier of (i) twelve months after the date of such termination of employment
due to disability and (ii) this option's originally stated expiration date.
Total disability shall not exist unless Optionee is permanently unable to engage
in any substantial gainful activity by reason of a medically determinable
physical and mental impairment which can be expected to continue for an
uninterrupted period of not less than 12 months, and such total disability is
demonstrated to the satisfaction of  the Company, in its discretion.

    12.  DEATH OF OPTIONEE.  If the Optionee dies (i) while an employee of the
Company, or (ii) within a period of three months after the termination of his
employment with the Company as provided in Paragraph 10, or (iii) within six
months after the termination of employment with the Company as provided in
Paragraph 11, this option shall terminate (notwithstanding Paragraph 3 of this
Agreement) on the earlier of (i) twelve months after the date of death and (ii)
this option's originally stated expiration date.  In such period following the
Optionee's death, this option shall be exercisable only by the Optionee's legal
representative or by the person or persons to whom the Optionee's rights under
this option shall pass by the Optionee's will or by the laws of descent and
distribution.

    13.  MISCELLANEOUS.  This Agreement shall bind and inure to the benefit of
the Company and its successors and assigns and the Optionee and any successor or
successors of the Optionee.  It is intended that this option will qualify as an
Incentive Stock Option under the provisions of Section 422 of the Internal
Revenue Code; provided, however, that Optionee hereby agrees to personally bear
whatever income tax and other burden which may arise if this option does not so
qualify and hereby releases the Company from and against any claim Optionee
might otherwise have in the event this option is not so qualified.


    IN WITNESS WHEREOF, the Company and the Optionee have executed this
Agreement in the manner appropriate to each, as of the day and year first above
written.

                                 SURMODICS, INC.
               RESTRICTED STOCK AGREEMENT/_______________________

     THIS AGREEMENT, made this _____ day of ______________, 19____, by and
between SURMODICS, INC., a Minnesota corporation (the "Company"), and
_________________________________________, (the "Employee").


                                   WITNESSETH:

     WHEREAS, the Company desires to keep personnel of experience and ability in
the employ of the Company and to provide a mechanism for additional compensation
to them dependent upon their continued employment with the Company and the
growth and profits of the Company;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained, the Company and the Employee hereby agree as follows:

     1.   GRANT OF BONUS SHARES.  The Company hereby authorizes an award of
_______________________ (__________) shares of voting common stock of the
Company (the "Bonus Shares") at the times and subject to the terms and
conditions hereinafter contained.  In the event of any increase or decrease in
the number of shares of the Company's voting common stock ("Common Stock")
resulting from a subdivision or consolidation of shares or the payment of a
stock dividend or any other similar increase or decrease in the number of shares
of Common Stock effected without receipt of any consideration by the Company,
the number of Bonus Shares subject to this Agreement shall be equitably adjusted
by the Company to reflect such change; any additional shares of Common Stock
which become part of the Bonus Shares shall be subject to all of the
restrictions and conditions applicable to the Bonus Shares.

     2.   WAITING PERIOD/ISSUANCE OF STOCK.  The Employee shall not be entitled
to any of the Bonus Shares unless the Employee is employed by the Company at the
end of the "Waiting Period", which shall be five years from the date of this
Agreement.  If the Employee remains in the employ of the Company at the end of
the Waiting Period, the Company shall promptly thereafter issue to the Employee
a stock certificate representing the Bonus Shares.  Upon such issuance, the
Employee shall have all of the rights of a shareholder with respect to such
shares, subject, however, to all of the restrictions and conditions set forth in
this Agreement.  In aid of such restrictions, the Employee shall, immediately
upon receipt of the certificate(s) representing such shares, appropriately
endorse such certificate(s) in blank and deliver such certificate(s) to the
Company to be held by the Company as hereinafter provided.

     3.   RESTRICTION PERIOD.  The "Restriction Period" shall be the five years
and seven months commencing on the date of this Agreement.  During the
Restriction Period, any Bonus Shares which have been issued to the Employee as a
result of the expiration of the Waiting


                                       -1-
<PAGE>


Period applicable thereto, shall be known as "Restricted Bonus Shares" and be
subject, during the Restriction Period, to the following restrictions:

          a.   The Restricted Bonus Shares may not be sold, exchanged,
               transferred, pledged, hypothecated, or otherwise disposed of
               voluntarily or involuntarily and any such attempted action
               shall be void and ineffective.

Until the end of the Restriction Period, all Restricted Bonus Shares shall, at
the discretion of the Company, be imprinted with a legend stating the
restrictions imposed by this Agreement.  At the end of the Restriction Period,
the Restricted Bonus Shares shall be free of the restrictions herein provided
and the Company shall issue and deliver to the Employee a certificate or
certificates representing such shares free of the legend described above, but
with any such legend as the Company customarily places on its Common Stock.

     4.   TERMINATION OF EMPLOYMENT.  Termination of employment shall occur if
the Employee ceases to be an employee of the Company for any reason whatsoever
(including, without limitation, voluntary resignation, involuntary termination
with or without cause, death, disability, termination as a result of the
reorganization, sale or liquidation of the company).  Upon any such any
termination of employment, the Employee's rights with respect to any Bonus
Shares for which the Waiting Period has not yet expired shall fully and
automatically lapse and terminate and Employee shall have no further rights
whatsoever with respect to that portion of the Bonus Shares.  With respect to
that portion of the Bonus Shares for which the Waiting Period has expired such
that Restricted Bonus Shares have been issued, the Employee's rights and
obligations with respect thereto are described in the preceding paragraph.  The
Employee acknowledges that there have been no promises or representations
concerning his or her continued employment and that such employment is and will
continue to be an "at will" relationship.

     5.   CONFIDENTIALITY.  The Employee agrees to maintain in strict confidence
the terms of this Agreement and the issuance of shares which are the subject
matter of this Agreement until and unless the Employee receives prior written
consent to disclosure from the President of the Company.

     6.   MISCELLANEOUS.

          a.   The Employee acknowledges that he or she has no rights as a
               shareholder with respect to any shares covered by this
               Agreement until the date of issuance of a stock certificate
               with respect thereto.  No adjustment shall be made for
               dividends, distributions, or other rights for which the
               record date is prior to the date such stock certificate is
               issued, except for the adjustment in shares as provided in
               Paragraph 1 hereof.

          b.   The Company may require as a condition to the issuance of
               any stock acquired pursuant to this Agreement that such
               stock be acquired for only investment if, in the opinion of
               counsel for the Company, such is required


                                       -2-
<PAGE>


               or deemed advisable under securities laws or any other
               applicable law, regulation or rule of any government or
               governmental agency.  In this regard, if and when requested
               by the Company, the Employee shall execute an investment
               letter to the effect that the Employee is acquiring such
               shares for investment purposes only and not with the
               intention of making any distribution thereof.

          c.   It is understood that the shares of Common Stock subject to
               this Agreement have not been registered under the Securities
               Act of 1933, as amended, or any applicable Blue Sky laws, or

                            NONQUALIFIED STOCK OPTION

     THIS AGREEMENT, made this ________ day of _________________, 19____ by and
between SurModics, Inc., a Minnesota corporation (the "Company"), and ,(the
"Optionee");

                              W I T N E S S E T H:

     WHEREAS, on or before on the date hereof, the Company's Board of Directors
authorized the grant of this option to the Optionee;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained, the Company and the Optionee hereby agree as follows:

     1.   GRANT OF OPTION.  The Company hereby grants to the Optionee, on the
date of this Agreement, the option to purchase _____________ shares of voting
common stock of the Company (the "Option Stock") subject to the terms and
conditions herein contained, and subject only to adjustment in such number of
shares as provided in Paragraph 7 hereof.

     2.   OPTION PRICE.  During the term of this option, the purchase price for
the shares of Option Stock granted herein is __________ per share, subject only
to adjustment of such price as provided in Paragraph 7 hereof.

     3.   TERM OF OPTION.  The term during which this option may be exercised
expires ten (10) years after the date of this Agreement.  This option shall be
exercisable during the term of this Agreement only with respect to the following
percentages of the Option Stock: (i) during the first year of the term, 20% of
the Option Stock; (ii) during the second year of the term, 40% of the Option
Stock; (iii) during the third year of the term, 60% of the Option Stock; (iv)
during the fourth year of the term, 80% of the Option Stock; and (v) during the
fifth through the tenth year of the term, 100% of the Option Stock. If this
option terminates for any reason, all unexercised options (including those not
yet exercisable) shall lapse.

     4.   PERSONAL EXERCISE BY OPTIONEE.  This option shall, during the lifetime
of the Optionee, be exercisable only by said Optionee and shall not be
transferable by the Optionee, in whole or in part, other than by will or by the
laws of descent and distribution.

     5.   MANNER OF EXERCISE OF OPTION.  This option is to be exercised by the
Optionee (or by the Optionee's successor or successors) by giving written notice
to the Company of an election to exercise such option.  Such notice shall
specify the number of

<PAGE>

shares to be purchased hereunder and shall be delivered to the Company at its
principal place of business. An option shall be considered exercised at the time
the Company receives such notice.  Upon receipt of such notice and subject to
the provisions of Paragraph 8 below, the Company shall, within a reasonable
time, and upon payment of the full purchase price for the shares to be
purchased, deliver to the Optionee certificates for the shares so purchased.
Payment for shares of Option Stock may be made in the form of cash or certified
check.  All requisite original issue or transfer documentary stamp taxes shall
be paid by the Company.

     6.   RIGHTS AS A SHAREHOLDER.  The Optionee or a transferee of this option
shall have no rights as a shareholder with respect to any shares covered by this
option until the date of the issuance of a stock certificate for the Option
Stock.  No adjustment shall be made for dividends (ordinary or extraordinary,
whether in cash, securities or other property), distributions or other rights
for which the record date is prior to the date such stock certificate is issued,
except as provided in Paragraph 7 of this Agreement.

     7.   ADJUSTMENT.  In the event of an increase or decrease in the number of
shares of Common Stock resulting from a subdivision or consolidation of shares
or the payment of a stock dividend or any other increase or decrease in the
number of shares of Common Stock effected without receipt of consideration by
the Company, the number of shares of Common Stock covered by each outstanding
option and the price per share thereof shall be equitably adjusted by the Board
of Directors to reflect such change.  Additional shares which may be credited
pursuant to such adjustment shall be subject to the same restrictions as are
applicable to the shares with respect to which the adjustment relates.

     Unless otherwise provided in the option agreement, in the event of the sale
by the Company of substantially all of its assets and the consequent
discontinuance of its business or in the event of a merger, exchange,
consolidation or liquidation of the Company, the Board of Directors may in
connection with the Board's adoption of the plan for sale, merger, exchange,
consolidation or liquidation, provide for the complete termination of this
Agreement and cancellation of outstanding options not exercised prior to a date
(prior to the effectiveness of such sale, merger, exchange, consolidation or
liquidation) specified by the Board or for the continuance of this Agreement
only with respect to the exercise of options which are exercisable as of the
date of adoption by the Board of such plan for sale, merger, exchange,
consolidation or liquidation; provided, however, that if Optionee holds options
exercisable as of the date of the Board's adoption of the plan for sale, merger,
exchange, consolidation or liquidation, he shall be given either (i) a
reasonable time within which to exercise such exercisable portions of his Option
prior to the effectiveness of such sale, merger, exchange, consolidation or
liquidation, or (ii) the right to exercise his Options as to an equivalent
number of shares of stock of the corporation succeeding the Company

<PAGE>


by reason of such sale, merger, exchange, consolidation or liquidation.  The
grant of this option shall not limit in any way the right or power of the
Company to make adjustments, reclassifications, reorganizations or changes of
its capital or business structure or to merge, exchange or consolidate or to
dissolve, liquidate, sell or transfer all or any part of its business or assets.

     8.   INVESTMENT PURPOSE.  The Company may require as a condition to the
grant and exercise of this option that any stock acquired pursuant to this
option be acquired for only investment if, in the opinion of counsel for the
Company, such is required or deemed advisable under securities laws or any other
applicable law, regulation or rule of any government or governmental agency.  In
this regard, if requested by the Company, the Optionee, prior to the acquisition
of any shares pursuant to this option, shall execute an investment letter to the
effect that the Optionee is acquiring shares pursuant to this option for
investment purposes only and not with the intention of making any distribution
of such share.

     9.   RIGHT OF FIRST REFUSAL.  Optionee shall not sell, assign, give, or
otherwise transfer or dispose of any of his shares of stock of the Company
acquired pursuant to this Agreement without first giving written notice to the
Company of his intention to sell or make disposition thereof, which notice shall
state the shares proposed to be disposed of, the amount of any consideration
offered, and the name of the prospective purchaser or assignee.  The Company, or
such one or more of its shareholders as the Company may designate, shall have,
for a period of ninety (90) days after receipt of such notice, an option to
purchase all, but not part, of the shares of the stock specified in such notice
on the same terms and conditions set out in the notice.  If the Company shall
fail, during the specified option period, to exercise the option, Optionee may,
at any time within sixty (60) days after the expiration of the option period,
sell or otherwise deal with or dispose of such stock in the manner and on the
terms set forth in the notice provided above.  If such sale or disposition is
not made within such sixty (60) day period, Optionee must again comply with all
provisions of this paragraph.

     10.  MISCELLANEOUS.  This Agreement shall bind and inure to the benefit of
the Company and its successors and assigns and the Optionee and any successor or
successors of the Optionee permitted by Paragraph 4 above.  Optionee hereby
agrees to personally bear whatever income tax consequences may arise from the
issuance of or exercise of this Option.

     IN WITNESS WHEREOF, the Company and the Optionee have executed this
Agreement in the manner appropriate to each, as of the day and year first above
written.

<PAGE>

    d.   "Improvement Patents" means any U.S. patents or patent applications,
    and all foreign counterparts, divisions, continuations, continuations in
    part, reissues and extensions thereof specifically pertaining to a Licensed
    Product:

         i.    which are filed on an invention conceived or reduced to
         practice by SurModics during the exclusive term (if any) of the
         license granted herein for that Licensed Product, and

         ii.   with respect to which SurModics has the right to grant a
         license, and

         iii.  which but for the license granted herein would be infringed by
         the manufacture, use or sale (or by a surface treatment process
         employed to produce that product or a reagent used in such process) by
         ZZ of Medical Products having a surface treated through the use of
         SurModics's Know-how.

    e.   "Medical Products" means products that are specifically described in
    Attachment B1, B2, and so forth.

    f.   "Licensed Products" means each of the separately sold Medical Products
    specifically described in Attachment B1, B2, and so forth, which bear a
    SurModics coating and which:

         i.    but for the license granted herein the manufacture, use or sale
         would infringe (or a surface treatment process employed to produce a
         product or a reagent used in such process would infringe) any claim of
         Patent Rights, or

         ii.   are produced through the use of SurModics's Know-how.

    g.   "Know-how" means SurModics's trade secrets and other technical
    information relating to the surface-treatment of medical devices and which
    SurModics has the right to transmit to others.  Know-how includes but is
    not limited to information contained in pending patent applications of
    Patent Rights and information that is Confidential Information as defined
    in Paragraph 13.

    h.   "Future Know-how" with respect to any Licensed Product means Know-how
    that is acquired by SurModics during the exclusive term (if any) of the

    respect to such billings and when separately shown on invoices:

         i.    discounts actually allowed and taken;

         charge upon or measured by the production, sale, transportation,
         delivery or use of Licensed Product and actually paid by ZZ;

         iii.  amounts allowed or credited on rejections or returns;

         iv.   transportation charges prepaid or allowed.

    Notwithstanding the above, if any Licensed Product is sold both separately 
    and as an integral part of a combination product containing one or more 
    integral components in addition to that Licensed Product, then Net Sales of 
    that Licensed Product resulting from sales of that combination product will 
    be calculated by multiplying the Net Sales for the combination product as 
    calculated above by the fraction A/B where A is the invoice price of the 
    Licensed Product as sold separately and B is the invoice price of the 
    combination product.

    A Licensed Product shall be considered sold when it is shipped or when it 
    is invoiced, whichever is earlier.  To assure SurModics the full royalty 
    payment contemplated in this Agreement, ZZ agrees that in the event any 
    Licensed Product is sold to an Affiliate for purposes of resale, Earned 
    Royalties for that Licensed Product shall be computed upon the selling price
    at which such Licensed Product would ordinarily be sold to a non-Affiliate, 
    rather than on the selling price of ZZ to the Affiliate.

    j.   "Affiliate" means any entity which owns at least 50% of, is at least
    50% owned by, or is under common (at least 50%) ownership with ZZ.

    B1, B2, and so forth, SurModics grants to ZZ, a separate worldwide license
    under SurModics's Patent Rights and Know-how to make, have made for it, use
    and sell that Licensed Product.  The license granted herein does not
    include the right to sublicense and is expressly limited to the specific
    Licensed Products defined herein.  Additional terms of each license are set
    out in the respective Attachments B1, B2, and so forth.  To the extent of
    any inconsistency between the terms set forth in the text of this Agreement
    and the terms set forth in Attachments B1, B2, and so forth, the terms set
    forth in the text of this Agreement shall be controlling.

    b.   Subject to the limited license granted herein, SurModics shall retain

3.  LICENSE FEES

    License Fees paid to SurModics by ZZ for each license granted herein are
    set out in the respective Attachment B1, B2, and so forth.

4.  ROYALTIES

    For each license granted herein, ZZ shall pay to SurModics a royalty for
    each quarter calendar year during the term of this License Agreement which
    will be the greater of the royalties of Paragraphs 4(a) or 4(b).

    a.   Earned Royalties shall be calculated as provided for in the respective
    Attachment B1, B2, and so forth.  No more than one Earned Royalty shall be
    paid by ZZ for any Licensed Product.  However, if any Licensed Product is
    covered by more than one Attachment B1, B2, and so forth, then the Earned
    Royalty rate shall be the highest rate specified for such Licensed Product.

    b.   Minimum Royalties shall be paid for each Licensed Product as provided
    for in the respective Attachment B1, B2, and so forth.

5.  ROYALTY PAYMENTS, REPORTS, RECORDS

    hereunder, ZZ will make written reports and payments to SurModics within
    thirty (30) days after the last day of each calendar quarter ending March
    31, June 30, September 30, and December 31. Each such report shall state
    the Net Sales, unit volumes, Earned Royalty, corrections of error in prior
    royalty payments, and data and calculations used by ZZ to determine such
    payments for each of the licenses corresponding to the respective
    Attachments B1, B2, and so forth.  Each report shall be accompanied by
    payment in full of the royalty due SurModics for that quarter.  The
    December 31 quarterly report shall also consist of a summary progress
    report regarding ZZ's relevant developmental, manufacturing scale-up,
    regulatory affairs, and marketing activities with respect to all Licensed
    Products along with a summary forecast of projected sales of Licensed
    Products and forecasted reagent usage for the next calendar year.

    b.   ZZ will maintain, for a period of five (5) years following the sale of
    Licensed Product, true and accurate records supporting the reports and
    payments made under this Agreement.  SurModics shall have the right to
    carry out an audit of such records no more frequently than once per
    calendar year by a certified public accountant of its choice.  Such
    accountant shall have reasonable access to ZZ's offices and the relevant
    records, files and books of account, and such accountant shall have the
    right to examine any other records reasonably necessary to determine the
    accuracy of the calculations provided by ZZ under Paragraph 5(a).  Such
    audit shall be at SurModics's expense except that if cumulative
    underpayment errors for any period are found that exceed 5% of the payment
    made to SurModics during that period being audited, then ZZ will bear the
    cost of such audit.

    c.   All royalties on sales of each Licensed Product to be paid to
    SurModics by ZZ under this Agreement shall be paid in U.S. Dollars to
    SurModics in the United States.  For the purpose of calculating Earned
    Royalties on sales outside the United States, ZZ shall utilize the average
    rate of exchange on the last business day of that calendar quarter as
    quoted in the Wall Street Journal.

    d.   Any sum required under U.S. tax laws (or the tax laws of any other
    government) to be withheld by ZZ from payment for the account of SurModics
    shall be promptly paid by ZZ for and on behalf of SurModics to the
    appropriate tax authorities, and ZZ shall furnish SurModics with official
    tax receipts or other appropriate evidence issued by the appropriate tax
    authorities sufficient to enable SurModics to support a claim for income
    tax credit in respect to any sum so withheld.

6.  DEVELOPMENT FEES

    ZZ agrees to pay SurModics for development efforts ("Development Fees")
    while working on ZZ's products at SurModics's then standard hourly rate for

    hourly rate includes direct labor costs plus direct labor overhead.
    SurModics shall additionally charge direct materials plus direct materials
    overhead of fifteen percent (15%).  Direct materials may include expenses
    such as travel and special equipment, but only as mutually agreed upon in
    writing.  SurModics shall invoice ZZ monthly for such Development Fees and
    payment is due within thirty (30) days thereafter.

7.  TERM

    a.   Unless earlier terminated, each license herein granted shall begin
    upon the Licensed Product Effective Date set out in the respective
    Attachment B1, B2, and so forth, and shall extend for each Licensed Product
    so licensed until expiration of the last to expire patent of Patent Rights
    that covers that product or for a period of fifteen (15) years following
    the first bona fide commercial sale of such Licensed Product, whichever is
    longer; provided, however, that for a Licensed Product that embodies or is
    manufactured through the use of Future Knowhow, the license herein granted
    shall extend until expiration of the last to expire patent of Patent Rights
    that covers that Licensed Product or for a period of fifteen (15) years
    from the date of the first bona fide commercial sale by ZZ of that Licensed
    Product, whichever is longer.

    b.   Upon expiration of the full term of the license granted herein for any
    Licensed Product, and upon full payment by ZZ to SurModics of any monies
    due under this Agreement, the license with respect to Know-how licensed
    herein for that Licensed Product shall be deemed paid up and non-exclusive
    (if any such license was exclusive), and SurModics may negotiate additional
    license agreements with any other party for that Licensed Product.

8.  PATENTS

    a.   ZZ shall see to it that all Licensed Products sold by ZZ shall be
    appropriately marked with the applicable patent numbers, in conformity with
    applicable law.

    b.   SurModics recognizes that it is an objective of ZZ to obtain patents
    on technology that it develops concerning chemicals having latent reactive
    groups and their uses.  ZZ recognizes that a vital part of SurModics's
    business involves the licensing of others under SurModics's patents and
    know-how to make, use and sell products, and that it is an objective of
    SurModics to enable its present and future licensees to exploit patent
    licenses from SurModics to produce and sell products without interference
    from any patent that ZZ might obtain.  A purpose of this Paragraph 8(b) is
    to establish a system under which each party may accomplish their
    respective objectives.

         i.    "ZZ Patents" means patents which (a) claim inventions conceived
         or first reduced to practice during the term of this Agreement solely
         by one or more ZZ employees or others who are required to assign
         inventions to ZZ, and (b) claim inventions relating to chemical
         species having photo-reactive or other latent reactive groups for the
         purpose of bonding chemicals such as synthetic polymers and
         biologically active materials onto surfaces or into matrices or to
         other molecules, the use of such chemicals species, or the products
         resulting from such use, and (c) which could be infringed by the
         manufacture, use or sale of any product or process covered by any
         claim of any patent that SurModics has the right to license to others.

         ii.   During the term of this Agreement, ZZ will provide SurModics
         with a copy of each proposed patent application for a ZZ Patent, and
         SurModics will provide comments concerning such application, including
         comments regarding inclusion of SurModics's Confidential Information,
         prior work done by SurModics in connection with the claimed invention,
         and the state of the art.  No application for a ZZ Patent shall be
         made without SurModics's prior written permission.  If SurModics can
         fairly show that it had substantial knowledge of the invention of any
         ZZ Patent application before receiving from ZZ that patent
         application, SurModics shall promptly notify ZZ and the parties shall
         cooperate in comparing records of conception of that invention to
         determine in good faith which party was the earliest to conceive the
         invention.

         iii.  SurModics shall have and is hereby granted a noncancelable,
         nonexclusive, worldwide license, with the right to sublicense, to
         make, have made for it, use and sell products and processes covered by
         each ZZ Patent to the extent that such manufacture, use or sale also
         is covered by any claim of any patent that SurModics has the right to
         license to others.  If ZZ was the earliest to conceive the invention
         of that patent, then the license granted to SurModics, and SurModics's
         right to sublicense, shall exclude the right to manufacture, use or
         sell Medical Products.


                                          6
<PAGE>

         iv.   In return for such license, SurModics will pay ZZ a total of
         five percent (5%) of the royalties (regardless of the number of ZZ
         Patents that are licensed to SurModics or the number of licenses
         involved) that SurModics receives from its sublicensees based on sales
         by its sublicensees of products that but for such sublicenses would
         infringe any Valid Claim of ZZ Patents.  Notwithstanding the above, if
         SurModics was the earliest to conceive the invention of any ZZ Patent,
         then the license granted to SurModics shall be considered paid-up.

    c.   Each party shall own an undivided one-half interest in inventions made
    jointly by one or more employees (or others who are required to assign
    inventions to a party) of each party ("Joint Inventions").  With respect to
    Joint Inventions, the parties agree that mutually acceptable patent counsel
    shall be retained to render an opinion as to the patentability thereof and
    to prepare, file, and prosecute such patent applications as may reasonably
    be required to provide protection for such inventions.  Jointly owned
    patents resulting therefrom ("Jointly Owned Patents") shall be considered
    Patent Rights in determining payment of royalties to SurModics under
    Paragraphs 4. With respect to Jointly Owned Patents:

         i.    SurModics agrees it will not grant licenses for the
         manufacture, use or sale of Medical Products as specified in
         Attachment B1, B2, and so forth, as of the filing date of such Jointly
         Owned Patents, without the advance written consent of ZZ.

         ii.   ZZ agrees it will not grant any licenses other than for the
         manufacture, use or sale of Medical Products as specified in
         Attachments B1, B2, and so forth, as of the filing date of such
         Jointly Owned Patents, without the advance written consent of
         SurModics.

         iii.  The limitations of Paragraphs 8(c)(i) and 8(c)(ii) apply only
         to Jointly Owned Patents and not to any other patents owned by either
         party.

         iv.   Should either party choose to bring suit for infringement by a
         third party of any Jointly Owned Patent, the party bringing suit shall
         have the right to join the other party as a party to the suit to the
         extent required by law.

    d.   The parties agree to execute and exchange upon request such documents
    as may be necessary or desirable to carry out the provisions of Paragraphs
    8(b) and 8(c).

9.  ALLOCATION OF ROYALTIES

    After five (5) years from the Licensed Product Effective Date, the Earned
    Royalty rate with respect to any Licensed Product shall be prospectively
    reduced to seventy percent (70%) of the Earned Royalty rate set out in
    Paragraph 4(a) and the respective Attachments B1, B2, and so forth, to the
    extent that and during the term that the


                                          7
<PAGE>

    manufacture, use or sale of that specific Licensed Product (or a surface
    treatment process or a reagent used in such process) is not covered by any
    Valid Claim of Patent Rights.  The provisions of this Paragraph 9 shall not
    apply to payment of Minimum Royalties as provided in Paragraph 4(b) and the
    respective Attachments B1, B2, and so forth.

10. TERMINATION

    a.   For each license granted herein:

         i.    ZZ shall have the right to terminate the respective Attachment
         B1, B2, and so forth, under which such license was granted, but only
         in its entirety, at any time upon ninety (90) days advance written
         notice.  Upon termination of such license, ZZ shall have no further
         rights under Patent Rights or Know-how.  However, ZZ shall be allowed
         to sell any inventory of Licensed Products existing at the time of
         termination for a period of six (6) months thereafter (thereafter
         destroying any remaining inventory), provided ZZ accounts for such
         sales of inventory and pays SurModics the appropriate Earned Royalty
         for such sales as set out in Paragraph 4(a) of this Agreement.

         ii.   SurModics may terminate this Agreement in whole or with respect
         to any license granted herein upon thirty (30) days written notice for
         any material breach or default by ZZ, including without limitation,
         failure to comply with the confidentiality provisions of Paragraph 13,
         failure to make reports and payments when due, failure to pay Minimum
         Royalties, and withholding or notice of intent to withhold any
         royalties provided for in this Agreement.  Said termination under this
         Paragraph  10(a)(ii) shall become effective at the end of the thirty
         (30) day period unless during that period ZZ shall first cure such
         breach or default.

         iii.  Upon termination of any license under any of the provisions of
         this Paragraph 10, but subject to the provisions of Paragraph
         10(a)(i), referring to the sale of inventory, ZZ shall cease making,
         having made for it, using and selling the Licensed Products of such
         license that are produced through the use of SurModics's Know-how.
         SurModics shall have the right to seek equitable relief to enforce the
         provisions of this Paragraph 10(a)(iii).

    b.   Either party may terminate this Agreement if the other party hereto is
    involved in insolvency, dissolution, bankruptcy or receivership proceedings
    affecting the operation of its business.

    c.   Notwithstanding the provisions of Paragraph 20, failure of ZZ to bring
    to market any Licensed Product by the date set out for that Licensed
    Product in the respective Attachment B1, B2, and so forth, to this
    Agreement shall permit SurModics to terminate the license for that Licensed
    Product upon thirty (30) days written notice at any time prior to the date
    ZZ begins bona-fide commercial sales of that Licensed Product.


                                          8
<PAGE>

    d.   In the event that all licenses granted herein are terminated,
    SurModics shall have the right to terminate this Agreement in its entirety
    upon written notice.

11. CONTINUING OBLIGATIONS SUBSEQUENT TO TERMINATION

    a.   Upon any termination of this Agreement or any of the licenses granted
    herein, the following rights and obligations shall continue to the degree
    necessary to permit their complete fulfillment or discharge:

         i.    SurModics's right to receive and ZZ's obligation to pay
         royalties to the extent owed; and

         ii.   ZZ's obligation to maintain records and SurModics's right to
         audit under Paragraph 5, with respect to sales made and to be made
         under Paragraph 10(a)(i); and

         iii.  Any cause of action or claim of either party, accrued or to
         accrue, because of any breach or default by the other party; and

         iv.   ZZ's obligation to maintain confidentiality under Paragraph 13;
         and

         v.    ZZ's obligation to forebear from use of SurModics's Know-how as
         provided in Paragraph 10(a)(iii); and

         vi.   The parties' obligations under Paragraphs 8(b) and 8(c) with
         respect to filing patent applications and payment of royalties on
         issued patents.

    b.   Within thirty (30) days of the date of termination of this Agreement,
    ZZ shall return to SurModics all copies of documents and other materials
    containing or disclosing any of SurModics's Confidential Information.

12. REPRESENTATIONS AND WARRANTIES

    a.   Each party warrants to the other that it has not accepted and will not
    accept commitments or restrictions with respect to its rights or
    obligations under this Agreement which will materially affect the value of
    the rights granted by SurModics nor the obligations undertaken by ZZ.

    b.   Each party has the full and unrestricted right to enter into this
    Agreement.

    c.   Nothing in this Agreement shall be construed as:

         i.    A warranty or representation by SurModics as to the validity or
         scope of any Patent Rights; or


                                          9
<PAGE>

         ii.   A warranty or representation that anything made, used, sold, or
         otherwise disposed of, or any process practiced, under any License
         granted in this Agreement is or will be free from infringement of
         patents of third persons; or

         iii.  A requirement that SurModics file any patent application,
         secure any patent, or maintain any patent in force; or

         iv.   An obligation to bring or prosecute actions or suits against
         third parties for infringement of any patent; or

         v.    An obligation to furnish any manufacturing or technical
         information not encompassed within Know-how; or

         vi.   Conferring any right on either party to use in advertising,
         publicity, or otherwise any trademark or trade name of the other; or

         vii.  Granting by implication, estoppel, or otherwise any licenses or
         rights under patents or other proprietary information of SurModics
         other than those included within Patent Rights and Know-how.

    d.   With respect to photo-reactive reagents supplied at any time by
    SurModics, SurModics disclaims all warranties, express or implied,
    including but not limited to warranties of merchantability, noninfringement
    and fitness for a particular purpose.  Notwithstanding anything to the
    contrary, SurModics shall not be liable for incidental, consequential,
    special, extraordinary or punitive damages of any description, whether for
    damage to reputation or goodwill, lost profits, claims of third parties or
    otherwise, whether such asserted damage purports to be based on warranty or
    guarantee, indemnity or other contract, contribution, negligence or other
    tort, or otherwise.

    e.   SurModics does not make any representations, extend any warranties of
    any kind, either express or implied, or assume any responsibilities
    whatever with respect to use, sale, or other disposition by ZZ or its
    vendees or transferees of Licensed Products incorporating or made by use of
    the Patent Rights and Know-how licensed under this Agreement.

    f.   ZZ represents that it will take action to reasonably bring to market
    and to sell Licensed Product throughout ZZ's world-wide marketing territory
    during the term of this Agreement.  Failure to adequately promote and
    market Licensed Product may, at SurModics's option, be interpreted as a
    material breach or default of this Agreement.  SurModics expects ZZ to
    demonstrate appropriate product development activities, participate in
    clinical trials, submit appropriate regulatory or governmental filings for
    appropriate marketing clearances, integrate the Licensed Product into ZZ's
    manufacturing operations, educate appropriate sales and marketing staff,
    and introduce and actively market the Licensed Product upon completion of
    product development and obtaining appropriate regulatory approvals.

13. CONFIDENTIALITY

    a.   Each party agrees to retain in confidence all Know-how and other
    information received from the other, including without limitation,
    information required to be maintained in confidence under prototype
    development or manufacturing scale-up or postscale-up relationships between
    the parties, for a period of fifteen (15) years from the date of disclosure
    or five (5) years from the date of termination of this Agreement, whichever
    is longer.  Each party agrees not to disclose any of such Know-how or other
    information to third parties nor to use the same except in accordance with
    this Agreement.  Each party's obligation of nondisclosure and non-use shall
    not apply to information which:

         i.    at the time of its disclosure to the receiving party is
         available to the public;

         ii.   after disclosure becomes available to the public through no
         fault of the receiving party;

         iii.  the receiving party can show was in its possession at the time
         of disclosure to it by the other;

         iv.   the receiving party can show was received by it from a third
         party without breach of a confidential obligation; or

         v.    is required to be disclosed by any governmental agency.

    Even after any of such information becomes available to the public, each
    party shall not disclose without the other's prior written approval the
    fact that such information was furnished by or originated with the other.

    b.   For the purpose of this entire Paragraph 13, Know-how or other
    information which is specific shall not be deemed to be within any of the
    specified exceptions merely because it is embraced by more general
    information in such exception.  In addition, any combination of features
    shall not be deemed to be within any of the specified exceptions merely
    because individual features are in such exception, but only if the
    combination itself and its principle of operation are in such exception.

    c.   Notwithstanding the above, ZZ specifically agrees that it will not
    disclose to any Affiliates or other third party any of SurModics's Know-how
    relating to the manufacture of SurModics's chemical reagents, the precise
    chemical composition of such reagents, how such reagents are tested, how
    they are quality controlled, and any other specific information concerning
    the production of such reagents.

    d.   The provisions of this entire Paragraph 13 shall survive termination
    of this Agreement for any reason.


                                          11
<PAGE>

    e.   Nothing herein shall in any way affect the obligations of the parties
    under any prior secrecy or confidential disclosure agreements, including
    the Prior Disclosure Agreement, which obligations shall continue in
    accordance with the terms of each such agreement to the extent not
    inconsistent with the present Agreement.

14. ASSIGNMENT

    This Agreement shall be binding upon and inure to the benefit of the
    parties hereto and their successors to the entire assets and business of
    the respective parties hereto.  Either party may assign its rights and
    obligations under this Agreement to a financially responsible third party,
    but only in connection with a complete transfer to the third party of the
    business to which this Agreement pertains.  The assigning party will so
    inform the other party to this Agreement without delay of any assignment
    made in accordance with the conditions of this Agreement.  This Agreement
    shall not otherwise be assignable by either party without the prior written
    consent of the other party.  Any and all assignments of this Agreement or
    any interest therein not made in accordance with this paragraph shall be
    void.

15. GOVERNMENT APPROVAL

    ZZ shall have the sole responsibility, at ZZ's sole expense, for obtaining
    any government approvals that may be required for the investigation or
    marketing of Licensed Products.

16. PRODUCT LIABILITY

    ZZ will defend and indemnify SurModics against all losses, liabilities,
    lawsuits, claims, expenses (including attorney's fees), costs, and
    judgments incurred through personal injury, property damage, or other
    claims of third parties, arising from the design, manufacture, use, or sale
    of Licensed Products.

17. NO WAIVER

    Any waiver of any term or condition of this Agreement by either party shall
    not operate as a waiver of any other or continued breach of such term or
    condition, or any other term or condition, nor shall any failure to enforce
    a provision hereof operate as a waiver of such provision or of any other
    provision hereof.

18. NOTICES

    All communications or other notices required or permitted under this
    Agreement shall be in writing and shall be deemed to be given when
    personally delivered, or when mailed by registered or certified mail,
    postage prepaid, and addressed as follows:

    Either party shall have the right to change the person and/or address to
    which notices hereunder shall be given, by notice to the other party in the
    manner set out above.

19. CAPTIONS

    The captions and headings of this Agreement are for convenience only and
    shall in no way limit or otherwise affect any of the terms or provisions
    contained herein.  This Agreement shall be construed without regard to any
    presumption or other rule requiring construction hereof against the party
    drafting this Agreement.

20. FORCE MAJEURE

    Neither party shall be liable for failure to perform as required by any
    provisions of this Agreement where such failure results from a cause beyond
    such party's reasonable control such as acts of God, regulation or other
    acts of civil or military authority, required approval(s) of government
    bodies, fires, strikes, floods, epidemics, quarantine restrictions, riot,
    delays in transportation and inabilities to obtain necessary labor,
    materials, or manufacturing facilities.  In the event of any delay
    attributable to any of the foregoing causes, the time for performance
    affected thereby shall be extended for a period equal to the time lost by
    reason of such delay.  The cumulative effect of all such delays under this
    Paragraph 20 shall not exceed one (1) year.

21. NO AGENCY

    Nothing in this Agreement authorizes either SurModics or ZZ to act as agent
    for the other as to any matter, or to make any representations to any third
    party indicating or implying the existence of any such agency relationship.
    SurModics and ZZ shall each refrain from any such representations.  The
    relationship between SurModics and ZZ is that of independent contractors.

22. SEVERABILITY

    Should any provision of this Agreement, or the application thereof, to any
    extent be held invalid or unenforceable, the remainder of this Agreement
    and the application thereof


                                          13
<PAGE>

    other than such invalid or unenforceable provisions shall not be affected
    thereby and shall continue valid and enforceable to the fullest extent
    permitted by law or equity.

23. GOVERNING LAW

    For all purposes under this Agreement, the parties agree and admit that
    jurisdiction and venue are proper in the Federal District Court, District
    of Minnesota.  This Agreement shall for all purposes be governed and
    interpreted in accordance with the laws of the State of Minnesota, except
    for its conflict of laws provisions.

24. ARBITRATION

    a.   In the event of any dispute concerning this Agreement, including its
    interpretation, performance, breach or termination, the procedures of this
    Paragraph 24 shall apply; provided, however, that either party shall have
    the unrestricted right at any time to seek a court injunction prohibiting
    the other party from making unauthorized disclosure or use of Confidential
    Information as provided for in Paragraph 13 or unauthorized use of
    SurModics's Knowhow as provided for in Paragraph 10(a)(iii).

    b.   Both parties will use good faith and reasonable efforts to resolve any
    dispute informally and as soon as practical.  If any such dispute is not
    resolved informally within a reasonable period, then the Chief Executive
    Officers of the parties will meet at a mutually agreeable time and place to
    attempt to resolve the dispute.

    c.   If the parties are unable to resolve a dispute as provided immediately
    above, either party may submit the dispute for resolution by mandatory,
    binding arbitration in the city of Minneapolis, MN (or such other place as
    the parties may mutually agree) under the auspices of the American
    Arbitration Association under it's Commercial Arbitration Rules.  Each
    party shall select one independent, qualified arbitrator and the two
    arbitrators so selected shall then select a third arbitrator in accordance
    with the Commercial Rules.  Each party reserves the right to object to any
    individual arbitrator (no matter by whom chosen) who has been employed by
    or affiliated with a competing organization.

    d.   The arbitrators, who shall act by majority vote, shall be empowered to
    decree any and all relief of an equitable nature, including but not limited
    to temporary restraining orders, temporary injunctions, and/or permanent
    injunctions, and shall also be able to award damages, with or without an
    accounting of costs.  Judgement on the award rendered by the arbitrator(s)
    may be entered into any court having jurisdiction thereof.  Each party
    shall bear its own costs and divide other reasonable arbitrator costs
    equally.

25. ENTIRE AGREEMENT

    This Agreement, together with the Prior Disclosure Agreement and all
    addenda, attachments, and writings required or contemplated hereby,
    constitutes the entire agreement between the parties with respect to the
    Licenses granted herein, and no party


                                          14
<PAGE>

    shall be liable or bound to the other in any manner by any warranties,
    representations or guarantees except as specifically set forth herein.
    This Agreement shall not be altered or otherwise amended except by an
    instrument in writing signed by both parties.

IN WITNESS WHEREOF, the parties have executed this Agreement on the date last

to any restrictions imposed by the local government.  If foreign exchange is not

local law.  In the event that a withholding or other tax is imposed on a royalty
payment due hereunder, the amount of royalty payable shall be the amount due
less the amount of such tax actually paid.

public accountant selected by BSI and acceptable to ABBOTT to have access during
ordinary business hours to examine such records referred to in paragraph 6.01 as

sufficiency of any royalty payment made under this Agreement.  ABBOTT shall only
be obligated to permit access once each year during the term of this Agreement
and to such of its records which directly relate to such royalty payments which
accrued or occurred within three (3) years prior to such request.

    7.01    Information and materials exchanged between the parties in
performing hereunder shall be deemed Confidential Matter as provided below.

    7.02    Confidential Matter received by a party from the other shall not be
disclosed by such receiving party to any third party, or used by such receiving
party for its own benefit, or for the benefit of a third party, except as
expressly provided herein.

    7.03    To be accorded treatment as Confidential Matter, however, such
Matter:

                                          11
<PAGE>

    (a)     must be first disclosed to the receiving party in writing and
plainly marked "Confidential" or words to the same effect; or

    (b)     if first disclosed orally, must be summarized in writing by the
disclosing party and plainly marked "Confidential", or words to the same effect,
and delivered to the receiving party within thirty (30) days of its first oral
disclosure to the receiving party; or

    (c)     if a physical thing, must be marked "Confidential", or words to the
same effect, or be accompanied by a writing specifically identifying such thing
as "Confidential".

Information and material provided by one party to the other hereunder which is
not identified as "Confidential" as provided above shall be considered as given
and received without any obligation of confidentiality or nonuse and the
receiving party shall be free to use such information in any way it sees fit,
subject only to any rights that the disclosing party may have under applicable
United States or foreign Patent Laws.

    7.04    Subject to Paragraph 15.01 (a) and (b), the specific terms of this
Agreement and the identity of the parties shall be considered Confidential
Matter.

    7.05    Further, the obligations of confidentiality and nonuse of this
Article 7 shall not apply to information or material:

    (a)     which is known by the receiving party prior to receipt from the
disclosing party as evidenced by documents in the possession of the receiving
party at the time of disclosure,

    (b)      which, after receipt from the disclosing party, is disclosed to
the receiving party by a third party having the legal right to do so,

    (c)     which is available to the public at the time of receipt from the
disclosing party,

    (d)     which becomes available to the public after receipt from the
disclosing party through no fault of the receiving party,

                                          12
<PAGE>

    (e)     which is independently developed by employees of the receiving
party not having access to Confidential Matter of the disclosing party,

    (f)     which is required, in the opinion of legal counsel of the receiving
party, to be disclosed for securing approval of governmental regulatory
agencies, including but not limited to the U.S. Food and Drug Administration, to
market LICENSED PRODUCTS, provided that the receiving party shall use its
reasonable efforts to seek to obtain from such agencies such protection for such
information against public disclosure as may be legally available,

    (g)     which is required, in the opinion of legal counsel of the receiving
party, to be disclosed for the filing of patent applications by the receiving
party, provided that the disclosing party is timely advised of the receiving
party's intention to include such information in a patent application of the
receiving party and the disclosing party does not notify the receiving party
within thirty (30) days of its objection to such disclosure, or

    (h)     which is reasonably necessary to be disclosed by the receiving
party to its individual agents or third parties who require knowledge thereof in
order to perform their normal duties or services, such as legal counsel,
certified public accountants, and the like, provided that such agents and third
parties are advised of and acknowledge the confidential nature of such
disclosure and agree in writing to maintain the confidential nature of the
disclosed information under terms no less rigid than those imposed upon the
parties to this Agreement.

    7.06    Each party shall use the same level of care in complying with the
obligations hereof respecting Confidential Matter as it does with respect to its
own information of similar nature.  The parties mutually represent and warrant
that each and every employee who will have access to the other party's
Confidential Matter hereunder shall be under contractual obligation not to
disclose or use such Confidential Matter except as directed by such other party.

party fails to perform any material obligation, covenant, condition, or
limitation herein, provided such other party shall not have remedied its failure
within ninety (90) days after receipt of written notice of such failure.

    8.02    If performance of this Agreement or any part hereof by either party
shall be rendered unenforceable or impossible under, or in conflict with any
law, regulation, or official action by any government agency having jurisdiction
over such party, then such party shall not be considered in default by reason of
failure to perform and the validity of all remaining provisions hereof shall not
be affected by such result.

    8.03    Abbott may terminate this Agreement beginning three (3) years after

shall not relieve ABBOTT of the obligation to pay royalties or make any other
payments owed to BSI which accrues prior to the termination date.

above, this Agreement shall continue:  (a) with respect to issued patents under

PROPRIETARY RIGHTS, perpetually.

obligations under Article 7 hereof shall survive and continue in effect for the
longer of three (3) years following such expiration or termination, or seven (7)
years from the effective date of this Agreement.

    8.06    Neither party shall be liable in damages for, nor shall this
Agreement be terminable or cancellable by reason of, any delay or default in any

God, regulation or law or other action of any government or agency thereof, war
or insurrection, civil commotion, destruction of production facilities or
materials by earthquake, fire, flood or storm, labor disturbances, epidemic, or

    10.03   In the event of infringement by any third party as described in
Paragraph 10.02, if BSI fails to proceed against such infringer within ninety
(90) days after receipt of a written request by ABBOTT to do so, or if BSI does

            all applications and responses to official communications before

            employees under 10(b), ABBOTT will reimburse BSI at a reasonable
            rate (the rate on the

                                          18

    vi)     ABBOTT shall do nothing to inhibit the issuance of the patent or
            patents drawn to the originally claimed multi-zone invention of

    (d)     If at any time during the life of this Agreement, ABBOTT intends to
allow any such application or patent issuing therefrom to lapse or become
abandoned or forfeited without having first filed a substitute, ABBOTT shall

                                  LICENSE AGREEMENT

    The License Agreement between Bio-Metric Systems, Inc. (now known as BSI
Corporation) and Abbott Laboratories dated May 30, 1989, as amended November 20,
1990, is further amended as follows:


    Delete Articles 4.04 and 4.05.


    Add the following new Article 4.09:

    4.09    ABBOTT shall have the right prospectively to credit against

against such royalties,* per calendar quarter or * of such royalties otherwise
due for such quarter, whichever is less, beginning with royalties for sales for
the calendar quarter beginning July 1, 1994, up to a maximum credit of *.  The
right granted to ABBOTT in this Article 4.09 is accepted by ABBOTT as a final
settlement of all royalties payable to BSI for sales made through March 31, 1994
and as final settlement of all credits and offsets against such royalties for
sales made through March 31, 1994 that were taken or that could have been taken

    confidential treatment.  Such material has been filed separately with the
    SEC.


<PAGE>


    10.02

    a.      In the event ABBOTT believes any third party is infringing any
patent included in PROPRIETARY RIGHTS, ABBOTT shall have the right, but not the
obligation, to prosecute the infringer by diligent and appropriate legal
proceedings, (including the Abbott Laboratories v. Biosite Diagnostics, Inc.,
currently pending in the United States District Court, N.D. IL), at ABBOTT's own
expense and in ABBOTT's own name, provided, however, that ABBOTT shall first
fully appraise BSI of the infringing product.

    b.      In the event that ABBOTT prosecutes such a proceeding and BSI
becomes a party, ABBOTT shall select counsel to represent BSI and shall
indemnify and hold harmless BSI from any damages, liabilities (excluding lost
royalties), cost and expense resulting from any such proceeding.  ABBOTT will
provide BSI with copies of all pleadings and BSI may be represented by BSI's own
counsel, acting in an advisory but not controlling capacity.  ABBOTT shall
promptly reimburse BSI for its costs of retaining outside counsel, as determined
under Article 10.02(d), in such proceedings.  ABBOTT will retain the
decision-making power on behalf of ABBOTT and BSI in pursuit or settlement of
such a proceeding.  All recoveries by way of cost, judgment, damages, lost
profits or settlements shall be retained by ABBOTT.  Notwithstanding the
foregoing, ABBOTT will not indemnify BSI in the event such damages, liabilities,
cost and expense is the result of any proceeding (i) brought by BSI against
ABBOTT, or (ii) brought by the third party against BSI which is not related to
the subject matter of this License Agreement.

    c.      In the event that ABBOTT prosecutes such a proceeding and BSI does
not become a party, ABBOTT will provide BSI with copies of all pleadings and BSI
may be represented by BSI's own counsel, acting in an advisory but not
controlling capacity.  ABBOTT shall promptly reimburse BSI for its costs of
retaining outside counsel, as determined under



                                          2

<PAGE>


Article 10.02(d), in such proceedings.  BSI's outside counsel's duties are
expected to be directed primarily to assist ABBOTT in the areas of document
discovery, witness preparation, attendance at depositions of BSI employees, and
preparing answers to interrogatories.  BSI may request attendance of BSI counsel
at hearings and trial, however, reimbursement for such attendance shall require
the consent of ABBOTT, which consent shall not be unreasonably withheld.

    d.      The parties contemplate that BSI's outside counsel fees in any one
proceeding under Article 10.02(b) or 10.02(c) will not exceed * and *,
respectively.  In the event that BSI's outside counsel fees in any one
proceeding under Article 10.02(b) or 10.02(c) exceed such amounts, BSI shall
bear the expense of fifty percent (50%) of such fees in excess of such amount.

    e.      For any proceeding brought under Article 10.02, ABBOTT shall have
the right to settle such litigation, but only upon the advance written
permission of BSI, which shall not be unreasonably withheld.  Settlement by way
of sublicense from ABBOTT which provides BSI with at least a * prospective
royalty based on sales by the sublicensee or its designees shall not require
BSI's advance written permission.  For any other settlement terms, ABBOTT and
BSI shall meet in good faith to determine mutually acceptable terms.  In the
event of settlement by way of a sublicense, ABBOTT shall have the right to
recover the amount reimbursed to BSI under Articles 10.02(b), 10.02(c) and
10.02(d) for its outside counsel fees by reducing by * the royalty payments due
BSI resulting from said sublicense until such reimbursed amount has been fully
recovered by ABBOTT.

    Article 10.03 is replaced with the following new Article 10.03.

    10.03   In the event of infringement by any third party as described in
Article 10.02, if ABBOTT fails to proceed against such infringer within one
hundred eighty (180) days after receipt of a written request by BSI to do so, or
if ABBOTT does not exercise due diligence in legal proceedings instituted
pursuant to Article 10.02 within sixty days (60) days after receipt of a written
request by BSI to do so, then BSI at its own discretion shall have the right but
not the obligation to prosecute the infringer by appropriate legal proceedings
in the name of BSI at BSI's own expense, and BSI may collect and retain for its
own use any and all recoveries by way of costs, damages, lost profits, past
royalties or settlements relating to the foregoing.  ABBOTT, at ABBOTT's own
expense, may be represented in such proceedings by ABBOTT's own counsel, acting
in an advisory but not controlling capacity.  ABBOTT shall complete all acts and
execute all documents as may be necessary in order to permit BSI to exercise
BSI's right pursuant to this clause.

    IN WITNESS WHEREOF, the parties have caused this instrument to be executed
by their duly authorized officers or representatives on the dates indicated
