                               PROSPECTUS SUMMARY
   

         This summary highlights information contained elsewhere in this
Prospectus that you should consider before investing in the Common Stock.
    

                                    Quantech
   
         Quantech Ltd. is completing development of a system that is expected to
run tests for a number of different medical conditions. We call our system the
DBx. The DBx consists of an instrument that sits on the top of a counter or cart
and reads disposable test cartridges developed by Quantech. Each Quantech test
cartridge will contain from one to four different medical tests such as those
for a heart attack or pregnancy. The DBx produces test results in a manner
different than other testing systems because it uses Quantech's proprietary
technology based on the quantum physics phenomenon known as surface plasmon
resonance ("SPR"), which involves the interaction of light with the electrons of
a metal.
    

   
         Excluding tests that can be conducted in the home, the overall world
wide diagnostic market is more than $18 billion. Routine and STAT (urgent)
laboratory tests currently account for the majority of this market. Routine
tests required in the hospital are conducted on testing systems located in
either the hospital's central laboratory or sent to a laboratory that is not
within the hospital. STAT tests are conducted by a hospital's central
laboratories or a smaller, more conveniently located version of the central
laboratories called STAT labs. Obtaining test results from central laboratories
can take a minimum of 45 minutes and up to three hours. This delay negatively
affects patient treatment and increases costs. Although STAT labs have been
established to reduce the time delay, test costs are higher in STAT labs than
central laboratories and turnaround time for tests is not always reduced. We are
designing the DBx to address what we believe is a pressing need for a test
system that can quickly, within 10 to 20 minutes, and cost effectively provide
test results, especially for patients with critical problems in emergency
departments.
    

         

   
         We expect the DBx to be launched with at least a panel of three heart
attack tests and a single test for pregnancy. Additional tests are expected to
be added to the DBx system to provide the number of different quantitative tests
the emergency department requires on an urgent basis. We received approval from
the FDA for our first heart attack test and have provided to the FDA submissions
for a second heart attack test and a pregnancy test. Submissions with the FDA
for additional tests and the instrument itself are expected to be made
throughout 1999.
    

   
         Quantech principal executive offices are located at 1419 Energy Park
Drive, St. Paul, Minnesota 55108. Its telephone number is (651) 647-6370 and its

                                  RISK FACTORS

   
         Investing in Quantech is risky. You should be able to bear a complete
loss of your investment. You should carefully consider the following risk
factors and other information in this Prospectus before deciding to invest in
shares of Quantech's Common Stock.
    

Immediate and Future Capital Needs

   
         Quantech does not have sufficient funds to complete commercial
development or commence production and sales of the DBx. Quantech anticipates
that its cash on hand and bank credit facility will allow it to maintain
operations through May 1999. Additional financing of approximately $10 million
of investment capital, funding by strategic partner(s) or licensing revenues
will be needed to operate through March 2000. This financing will be used to
develop and submit to the FDA additional tests, complete clinical evaluation of
the DBx, establish manufacturing capabilities and prepare for sales of the DBx.
Quantech does not have any commitments for any such additional financing and
does not anticipate receiving any additional significant funding from commercial
lenders. There can be no assurance that any such additional financing can be
obtained on favorable terms, if at all. Any additional equity financing may
result in dilution to Quantech stockholders.
    

Going Concern Uncertainty

         

   
         Quantech has not had any significant revenues to date. As of June 30,
1998 and December 31, 1998, we had an accumulated deficits of $18,057,048 and
$20,843,033, respectively. The report of the independent auditors on Quantech's
financial statements for the year ended June 30, 1998, includes an explanatory
paragraph relating to the uncertainty of Quantech's ability to continue as a
going concern, which may make it more difficult for Quantech to raise additional
capital.
    

   
No Assurance of Final Development of DBx
    

   
         Components of the DBx system are under various stages of development.
Until DBx system development is completed and cleared through the FDA, there can
be no assurance that the DBx system will be finished according to our current
development timetable and budget. Failure to timely finish on budget will
require Quantech to seek funding greater than currently anticipated, thus
intensifying the risks described in Immediate and Future Capital Needs above.
Additionally, the final price that we will need to charge to cover the costs of
the DBx instrument and the test cartridges cannot be determined until
development is complete and FDA clearances have been obtained. If Quantech
cannot receive FDA approval and offer the DBx system with certain required
features at a cost acceptable to potential customers, it will be impossible for
Quantech to continue operations.
    

   
Dependence on the Ability of the DBx to Provide Quick, Reliable and Economical 
Test Results
    

   
         In general, the commercial success of Quantech's DBx system will depend
upon its acceptance by the medical community and third-party payers as a
reliable and economical product. The approval of the purchase of diagnostic test
systems by a hospital is generally controlled by its central laboratory. We
    

<PAGE>

   
expect that there will be resistance by some central laboratories to a new
system until it is proven to have a level of accuracy and precision comparable
to current hospital tests. Finally, the DBx must provide results of STAT tests
quicker than current hospital tests for emergency department doctors.
    

Lack of Marketing Experience
   
         We have had no experience in marketing the DBx. We intend to market our
system in both the United States and in foreign markets through a strategic
partner(s) with an established distribution system, but no assurance can be
given that such an arrangement can be made. If such a strategic relationship is
not entered into prior to product launch, we will market our system through a
combination of our own sales force and distributors. Establishing a sales and
marketing capability sufficient to support the level of sales necessary for us
to attain profitability will require substantial efforts and significant
management and financial resources. There can be no assurance that we will be
able to recruit and retain direct sales and marketing personnel, engage
distributors or have our marketing efforts be successful.
    
         
Limited Manufacturing and Production Experience
   
         To be successful, we must timely manufacture sufficient quantities of
the DBx and test cartridges in compliance with regulatory requirements, such as
the FDA's Good Manufacturing Practices while maintaining product quality and
acceptable manufacturing costs. The instrument and many components of the test
cartridges will be manufactured by outside vendors. We have not entered into
agreements with any of these vendors. There can be no assurance that we can
engage such vendors. Further, if engaged, the limited control we have over any
third party manufacturers as to timeliness of production, delivery and other
factors could affect our ability to supply products on a timely basis.
    

   
         We ultimately intend to chemically coat and assemble test cartridges
ourselves. We have never operated a manufacturing/assembly business. We will
have to establish a manufacturing facility, or contract for such services with a
third party, which is registered with the FDA.
    

   
Failure to Comply with Government Regulations
    

   
         The DBx instrument and test cartridges are human diagnostic medical
devices subject to regulation by the United States FDA and agencies of foreign
countries. The FDA regulates the DBx as a medical device that requires clearance
before sales can be made in the United States. We believe that such pre-market
clearance can be obtained for our instrument and substantially all of our test
cartridges through submissions of a 510(k) pre-market notification demonstrating
the particular product's substantial equivalence to another device legally
marketed under a similar clearance. There can be no assurance that the FDA or
other government regulators will approve the DBx system and test cartridges in a
timely manner or at all. Delay in approvals, or failure to achieve approvals,
would increase the capital necessary to maintain operations and make it more
difficult to raise required funds.
    

   
Multiple Levels of Competition
    

         

         

   
         The medical testing market is highly competitive. We expect that
manufacturers of central and STAT laboratory testing equipment will compete to
maintain their market shares. Also, point of care testing products exist and
additional products are likely to be introduced to compete with certain tests to
    

<PAGE>

   
be performed on the DBx instrument. All of the industry leaders and many of the
other companies participating in this market have substantially greater
resources than the resources available to us, including, but not limited to,
financial resources and skilled personnel. Current central lab systems are also
well accepted and entrenched so that sales of the DBx may require a significant
sales effort to gain market share. If the features and costs of the DBx system
are not compelling it will not successfully compete in its market.
    

Compliance with CLIA

   
         Use of Quantech's DBx system will be subject to the Clinical Laboratory
Improvement Act of 1988 ("CLIA"). This regulation governs the qualifications of
persons supervising a laboratory test and the persons performing the laboratory
test. Quantech has based its marketing plan on the belief that the DBx system
will be classified as a test of moderate complexity. However, we have not sought
the necessary regulatory approval of this classification. In practical terms,
performing a test of moderate complexity means that the individual supervising
the test must be well educated and well trained, but the individual operating
the system requires no formal laboratory education and only task-specific
training. If our DBx system is not classified as a test of moderate complexity,
we would not have a user-friendly operation advantage, which could have an
adverse affect on sales.
    

   
Single Product and Technology Basis
    

         

   
         The DBx will be Quantech's only initial product and is based upon a
single set of core technologies. We operate in a market characterized by rapid
and significant technological change. While we are not aware of any developments
in the medical industry which would render our current or planned product less
competitive or obsolete, there can be no assurance that future technological
changes or the development of new or competitive products by others will not do
so. To remain competitive, we will need continually to make substantial
expenditures for development of both equipment and additional tests.
    

         

   
Failure to Maintain Patent Protection
    

   
         No assurance can be given that we will be able to protect our
proprietary technology. We are not aware of any issued patents that would
prohibit the use of any technology we currently have under development. However,
patents may exist or be issued in the future to other companies covering
elements of the DBx. The existence or issuance of such patents may require us to
make costly significant changes in the design of our systems or operational
plans. We have not conducted an independent patent search or evaluation with
respect to our patented technology. Ares-Serono, the company licensing certain
technology to us made no warranties as to the enforceability of any of the
patents or the commercial potential of the technology. Although Ares-Serono may
defend the patents they have licensed to us, we will be responsible for the
defense of any patents Ares-Serono elects not to defend and all of those issued
to us. The cost of patent litigation can be very substantial.
    

Dependence on the Ares-Serono License

   
         We are dependent upon the worldwide license we acquired from
Ares-Serono to certain patents, proprietary information and associated hardware
    

<PAGE>

   
related to the SPR technology. The Ares-Serono license calls for ongoing
royalties based on revenues and a $150,000 minimum royalty payment on December
31, 1999. If the minimum royalty is payment not made, Ares-Serono has the right
to cause a reversion to it of a royalty-free license, thereby depriving us of
our exclusive rights under the Ares-Serono license.
    
         
Dependence on Personnel

   
         We have a small number of employees. Although we believe we maintain a
core group sufficient for us to effectively conduct our operations, the loss of
any of our personnel could, to varying degrees, have an adverse effect on our
operations and system development. The loss of either Robert Case, our CEO, or
Greg Freitag, our COO and CFO, would have a material adverse affect on Quantech.
    

         

   
Shares Eligible for Future Sale May Have Adverse Affect of Price and Liquidity
    

   
         As a result of this Registration Statement, all shares of Quantech's
outstanding Common Stock are eligible to be sold in the public market along with
all shares that may be obtained upon exercise of outstanding options, warrants
or conversion of Series A Convertible Preferred Stock. The sale of a substantial
number of shares could adversely affect the market price and liquidity of
Quantech's securities. Such potential adverse affects on price and liquidity, or
the concern over these issues, could make it more difficult for Quantech to
raise required future funds.
    

   
                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
    

   
         Certain statements in this Prospectus are not historical facts but are
forward-looking statements. Such forward-looking statements may be identified by
the use of terminology such as "anticipate," "believe," "estimate," "expect,"
"intend," "may," "plans," "project," and similar expressions. Such statements
involve risks and uncertainties and should be evaluated in light of the risk
factors discussed above. Should one or more of these risks or uncertainties
materialize, or should underlying assumptions prove incorrect, actual outcomes
may vary materially from those indicated.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   
         The following discussion should be read in conjunction with the
consolidated financial statements of Quantech and the notes thereto included
elsewhere in this Prospectus.
    

         

Results of Operations

   
For the Six Months Ended December 31, 1998 and 1997
    

   
         Quantech has incurred a net loss of $20,752,248 from September 30, 1991
(date of inception) through December 31, 1998 due to expenses related to
formation and operation of Quantech's predecessor, Spectrum Diagnostics Spa. in
Italy, continuing costs of raising capital, normal expenses of operating over an
extended period of time, expenditures on research and development, royalty
payments related to the SPR technology and interest on borrowed funds. In
addition, an investment of $3,356,629 was made when Quantech purchased the
exclusive rights to the SPR technology.
    

   
         For the six months ended December 31, 1998, Quantech had interest
income of $1,068 compared to $9,907 for the same period in 1997. This decrease
was a result of less cash on hand as proceeds obtained from Quantech's private
placements of securities have been used for operations, research and development
and to reduce borrowing from its $750,000 bank credit facility.
    

   
         General and administration expenses increased to $931,641 for the six
months ended December 31, 1998 from $484,251 for the same period in 1997. The
increase in general and administrative spending was primarily due to costs
associated with financing activities, including commission expense of $198,000,
charges of $78,000 for warrants and options issued in connection with financing
activities and professional fees of $39,000. Additional expenses related to
Quantech's expansion also contributed to the increase in general and
administration expense. Quantech anticipates that these expenses will be lower
during the quarter ending March 31, 1999 due to reduced financing activity, but
then will increase as Quantech raises additional funding, completes development
of its system and begins to manufacture and distribute its products.
    

   
         Research and development costs increased to $974,645 in the six months
ended December 31, 1998 from $595,349 in the same period of 1997. This increase
was primarily due to expenses related to the preparation of 510(k) submissions
to the FDA and engineering design work on the DBx commercial instrument and
related test cartridges, including charges of $200,500 for warrants and options
issued in connection with research and development agreements. Quantech expects
R&D spending to remain flat during the quarter ending March 31, 1999 and then
increase as Quantech completes the commercial development of its system,
conducts additional FDA work and begins to establish higher volume manufacturing
capabilities.
    

   
         Minimum royalty expense increased to $75,000 during the six months
ended December 31, 1998 compared to $37,500 for the same period in 1997. This
increase was due to the accrual for the minimum payment made in December 1998.
Royalty expense is expected to remain at $37,500 per quarter through December
1999 (see Notes to Financial Statements, Note 2 - License Agreement).
    

<PAGE>

   
         Interest expense for the six months ended December 31, 1998 increased
to $714,982 compared to $99,821 during the same period in 1997 primarily due to
increased debt from the sale of promissory notes including a $546,902 charge to
reflect the beneficial conversion feature of the now converted notes. Interest
expense is expected to decrease during the quarter ending March 31, 1999 due to
the effect of the conversion of the promissory notes for all three months of the
quarter, and then to remain flat.
    

   
         For the six months ended December 31, 1998 Quantech had losses of
$2,695,200 as compared to $1,207,014 for the same period in 1997. The higher
loss for the quarter was primarily due to increased operating expenses partially
offset by lower interest expense. A substantial portion of the increased loss
for the six-month period was interest cost, with the remaining increase a result
of higher operating expenses and lower interest income.
    

   
For the Year Ended June 30, 1998 and 1997
    

   
         Quantech incurred a net loss of $18,057,048 from September 30, 1991
(date of inception) through June 30, 1998 due to expenses related to formation
and operation of Spectrum Diagnostics Spa. in Italy, continuing costs of raising
capital, normal expenses of operating over an extended period of time,
expenditures on research and development, royalty payments related to the SPR
technology and interest on borrowed funds. In addition, an investment of
$3,356,629 was made when Quantech purchased the rights to the SPR technology.
    

   
         For the year ended June 30, 1998 Quantech had interest income of
$12,435 compared to $80,854 for the 1997 fiscal year as a result of less cash on
hand as proceeds obtained from Quantech's private placements of securities have
been used for operations and research and development.
    

   
         General and administration expenses decreased from $1,799,117 for the
year ended June 30, 1997 to $1,221,196 for the year ended June 30, 1998. The
decrease in general and administration expenses resulted from the restructuring
that Quantech implemented in the second half of 1997. The restructuring was
aimed at reducing expenses and focusing Quantech's resources on completing
development of its diagnostic system. Changes that were made included reducing
the number of employees, consultants and outside services employed in the
administrative functions. Quantech anticipates that these expenses will increase
significantly in the future as Quantech completes development of its system and
begins to manufacture and distribute its products.
    

   
         Research and development costs decreased from $2,114,586 in 1997 to
$1,608,361 in 1998. The decrease was due to the above mentioned restructuring,
with cost reductions resulting primarily from reduced outside contract
development work as Quantech focused its resources on completing system
development with a reconfigured internal development team. Spending began to
increase significantly, however, near the end of fiscal 1998 as Quantech
incurred expenses necessary to prepare and file its first 510(k) submission with
the FDA, and engaged outside design engineering firms to assist in finishing
development of the commercial version of its DBx system. Quantech expects R&D
spending to continue at a considerably higher rate in fiscal 1999 as Quantech
completes such development, conducts additional FDA submission work and begins
to establish higher volume manufacturing capabilities.
    

<PAGE>

         Minimum royalty expense increased to $112,500 in 1998 as compared to
$75,000 in 1997 as a result of the higher minimum royalties owed under
Quantech's amended license with Ares-Serono. Royalty expense is expected to
increase to $150,000 in fiscal 1999 to reflect the minimum royalties owed under
Quantech's amended license with Ares-Serono.

   
         Interest expense increased in 1998 to $719,126 as compared to $17,611
in 1997. The higher interest expense was primarily the result of increased debt
from the sale of promissory notes including a $441,542 charge to reflect the
beneficial conversion feature of the notes. Interest expense during fiscal 1999
is expected to be similar to 1998, but may change depending upon the future
capital structure of Quantech.
    

         For the year ended June 30, 1998 Quantech had a loss of $3,648,748 as
compared to $3,925,460 for the same period ended June 30, 1997. This decrease
was a result of the decrease in research and development and general and
administrative expenses in 1998 exceeding increases in such period in minimum
royalty and interest expenses and the decrease in interest income.

         

Liquidity and Capital Resources

   
         From inception to December 31, 1998, Quantech has raised approximately
$20,350,000 through a combination of public stock sales, private stock sales and
issuance of debt obligations. In November and December 1998, Quantech raised net
proceeds of $1,669,475 from the sale of 600,617 shares of its Series A
Convertible Preferred Stock to accredited investors. The shares were priced at
$3.00 per share and each share of Series A Preferred Stock is convertible into
four shares of Common Stock. Noteholders also converted $3,374,138 of Quantech's
promissory notes into 1,124,715 shares of the Series A Preferred Stock in
November 1998. Additionally, in November 1998 Quantech issued a warrant
Millenium Medical Systems to purchase 1,800,000 shares of Common Stock at $1.10
per share in exchange for engineering development work.
    

   
         Quantech anticipates that its cash on hand and bank credit facility,
which had $400,000 available as of March 1, 1999, along with the lower cash
requirements resulting from the Millennium development agreement will allow it
to maintain operations through May 1999. Additional financing of approximately
$10 million through March 2000 will be needed to develop and submit to the FDA
additional tests, complete clinical evaluation of the DBx, establish
manufacturing capabilities and prepare for sales of the DBx. Quantech is
currently reviewing multiple avenues of future funding including private sale of
equity or debt with equity features or arrangements with strategic partners.
Quantech does not have any commitments for any such financing and there can be
no assurance that Quantech will obtain additional capital when needed or that
additional capital will not have a dilutive effect on current stockholders. See
"Risk Factors--Immediate and Future Capital Needs." Although Quantech has a
limited lending arrangement with its bank to a maximum of $750,000, all of which
credit line will be used by the end of May 1999, it does not anticipate
receiving any additional significant funding from commercial lenders.
    

   
         Quantech currently has outstanding 2,721,534 shares of Common Stock,
and 1,702,706 shares of Series A Preferred Stock convertible into 6,810,824
shares of Common Stock. It also has options and warrants outstanding to purchase
an additional 6,256,581 shares of Common Stock at exercise prices from $0.75 to
    

<PAGE>

   
$14.40. Because these options and warrants expire from May 2000 through December
2003, Quantech is not relying on any significant proceeds from the exercise of
options and warrants in the next 12 months. However, the exercise of any
significant number of options and warrants could provide necessary funding and
such exercises could occur if Quantech continues to meet its milestone schedule
on a timely basis.
    

   
         Quantech incurred capital expenditures of $36,046 in the six month
period ended December 31, 1998. Quantech anticipates significant capital
expenditures in the future for laboratory and production equipment and office
expansion as Quantech nears product introduction. The timing and amount of such
expenditures will be governed by Quantech's development and market introduction
schedules which are subject to change due to a number of factors including
development delays, FDA approval and availability of future financing.
    

Year 2000 Compliance

   
         We believe our internal information and non-information systems are
year 2000 compliant. Quantech is in a stage of development of its products at a
time when awareness of year 2000 issues allows it to build year 2000 compliance
into its products and operations. We are diligently ascertaining at each step of
development that our products are compliant and are in the process of contacting
key suppliers to address their exposure to year 2000 related risks. We have,
therefore, not developed any contingency plans relating to year 2000 issues and
have not budgeted any funds for year 2000 issues. Although we believe that our
systems are year 2000 compliant, unanticipated year 2000 problems may arise
which, depending on the nature and magnitude of the problem, could adversely
affect our business. Furthermore, year 2000 problems involving third parties may
have a negative impact on our suppliers and potential customers, the general
economy or the ability of businesses to receive essential services such as
telecommunications and banking. Any such occurrence could adversely affect our
business.
    


<PAGE>


                                    BUSINESS
   
General
    

   
         Quantech Ltd. is completing development of a system that is expected to
run tests for a number of different medical conditions. We call our system the
DBx. The DBx consists of an instrument that sits on the top of a counter or cart
and reads disposable test cartridges developed by Quantech. Each Quantech test
cartridge will contain from one to four different medical tests such as those
for a heart attack or pregnancy. The DBx produces test results in a manner
different than other testing systems because it uses Quantech's proprietary
technology based on the scientific phenomenon known as surface plasmon resonance
("SPR").
    

         

   
         We are designing the DBx primarily for the emergency department. The
DBx is expected to have the range of available tests and quality performance of
hospitals' central and STAT labs, but with test time turnaround of 10 to 20
minutes. The system will analyze both whole blood and urine without preparation
or addition of other substances or removal of the sample from the collection
device. We believe this ease of use and the ability to locate the DBx in the
emergency department will economically provide physicians with faster test
results than hospital central or STAT laboratories.
    

         

   
         We have received approval from the FDA for our first heart attack test,
which will test for the cardiac market myoglobin. We have submitted to the FDA
applications for a second heart attack test, which will test for the cardiac
marker CK-MB, and for a pregnancy test, which will test for hCG. Initial launch
of the DBx system is expected in late 1999. Quantech believes the capabilities
of its DBx system as a diverse diagnostic testing platform will meet the needs
of the critical care STAT testing market enabling Quantech to be competitive in
the global medical diagnostics market.
    

   
Quantech's DBx System
    
         The Instrument

   
         The DBx system consists of a reading instrument and disposable test
cartridges. The instrument will process up to four tests at a time on a single
disposable test cartridge. Additional reading ports will be designed to be
attached to the base instrument to allow more than one test cartridge to be read
by the instrument at one time. Because the DBx is a biosensor system it can
convert biological data into digital signals. This will allow future designs to
take advantage of advances in microcomputer technology. Most importantly, the
instrument is designed to be compatible with new test cartridges that are
introduced into the market by Quantech without system obsolescence or
significant re-training of personnel.
    

   
         The instrument will be of a size capable of sitting on a bench top or
cart and of being moved from room to room if necessary. It contains a white
light source, a microprocessor, a number of optical components, a computer touch
screen and barcode readers. The light is split into a number of channels,
providing for quality controls and multiple tests per test cartridge. When the
test cartridge is inserted into the instrument, an internal barcode reader
identifies the type of test to be run. A touch screen and/or an external barcode
reader will enable the user to enter both a user number and the patient or
specimen ID number. The instrument's computer screen will display results of a
given test. The data or results produced by the instrument will also be stored
on an internal hard drive, downloaded to the hospital information system, and
may be provided on a hard copy through use of a printer.
    

<PAGE>

   
         It is anticipated that critical care units such as the emergency
department will have several DBx instruments at various locations. Quantech
intends to offer several industry standard instrument rental programs under
which a hospital may obtain and retain the DBx without cost as long as a
specified number of test cartridges are purchased. For customers who wish to
purchase the instrument, the retail price is anticipated to be $15,000.
    

   
         The Disposable Test Cartridges
    

   
         Quantech's disposable test cartridge consists of an injection molded
plastic carrier containing a metal coated sensor surface. The metallic surface
is overlaid with different chemicals depending on the test or tests to be
performed by a particular cartridge. An important feature of the Quantech test
cartridge will be the ability to attach a standard vacutainer tube which is used
to draw blood. The ability to put blood into the DBx test cartridge without
removing it from the tube will make the DBx easier to use and the user will have
minimal exposure to the blood sample. Future cartridges for certain tests may
also be configured to handle samples of urine and other body fluids.
    

   
         Because the necessary chemicals are already in the test cartridge, an
operator will not be required to add any other chemicals. Lack of handling
chemicals by the operator translates into easier use than current testing
systems found in the central laboratory and more immediate results. Test
cartridges will be configured to provide single tests or multiple
clinically-related tests. Because the same test cartridge configuration may be
used for all tests, manufacturing and quality control costs should be minimized.
Cartridges are expected to have retail prices ranging from $12.00 to $35.00 per
test cartridge depending on the tests provided. Additional development of the
cartridge is currently being conducted and future development will be undertaken
to expand the number of tests that may be performed in general and on each
cartridge.
    

         Comparison of Product Technologies

   
         A number of basic methods, whether performed manually or by automated
instruments, are utilized in medical testing including immunoassays, DNA probes
and chemical reactions. Each of these testing methods requires the performance
of a series of operations by a skilled technologist. These operations include
sample preparation, addition of reagents or chemicals, further method-specific
manipulations, and reading and interpretation of raw data. Each testing method
also requires a specific instrument to perform the particular test. Central and
STAT laboratory automated testing systems have mechanized, rather than
eliminated many of these steps and have been unable to combine a number of
different testing methods or technologies into a single system. The DBx, in
contrast, is expected to be able to be used for these and other basic testing
methods within a single instrument, but without complicated processing by the
operator.
    

   
         Central and STAT laboratories provide quality results on a number of
different tests. However, tests that are needed urgently take from 45 minutes to
three hours and disrupt the batch testing of central labs. Although STAT labs
have quicker turnaround time with the quality advantages of the central lab,
    

<PAGE>

   
personnel and equipment requirements of STAT labs result in high test costs.
Point of care testing instruments have reduced test turnaround time, and in some
instances have lower test costs than STAT labs, but fail to meet laboratory
quality and critical care needs due to:
    

   
     o The limited number of tests that can be performed; 
     o Lack of interface to laboratory computer information system; 
     o Manipulation of patient blood sample;
     o Non-similarity to central laboratory results; and 
     o Lack of quantitative results.
    

   
         Our DBx is designed to combine the advantages of central laboratory and
point of care testing while eliminating or limiting the disadvantages of these
alternatives by providing the following features and capabilities:
    

   
     o Ability to perform a number of different STAT tests (heart attack,
       pregnancy, white blood count panel, coagulation panel,
       electrolytes, amylase, therapeutic drugs, drugs of abuse panel,
       etc.)
     o Rapid test result turn-around time (10-20 minutes) 
     o Quantitative results using whole blood (no sample processing by user) 
     o Multiple tests on one cartridge (up to four clinically related tests 
       per disposable) 
     o User-friendly 
     o Cost effective (less than STAT lab test costs)
     o No addition of reagents by the operator
     o Transportable instrument can be placed on top of bench or cart 
     o Similarity to central laboratory test results 
     o Whole blood/closed tube (vacutainer) patient sample capability 
     o Full-time laboratory information system computer interface 
     o Automatic user/patient/test/quality control input
    

The Market

   
         Excluding home testing, the overall world wide medical testing
(in-vitro diagnostic) market is more than $18 billion. Central and STAT
laboratories currently account for the majority of this market with testing
divided between non-urgent or routine tests and urgent (STAT) tests. Quantech is
focused on the STAT testing portion of this market. STAT tests are required in
areas such as surgical suites, intensive care units, coronary care units and
emergency departments because of the time sensitive nature of their treatment.
However, results of STAT tests from the central laboratory can take 45 minutes
to three hours. This delay affects patient treatment and increases costs.
Although STAT labs have been established to reduce this time delay, test costs
are higher than the central laboratory and reduced test time turnaround is not
always achieved.
    

   
         Pressure has increased to reduce the length of patient stay in
hospitals and provide a greater portion of services in ambulatory and outpatient
settings. Because the cost of providing care in critical care units far exceeds
those of general medical or surgical units, a primary goal of critical care
medicine is to make a quick and accurate diagnosis for a patient so they may be
    

<PAGE>

   
treated, sent home or moved to a different area of the hospital. Point of care
testing has emerged in response to these demands but, as previously discussed,
lack of central and STAT lab features have kept these point of care instruments
from penetrating the critical care testing market. We have chosen a strategic
direction designed to promote the inherent technological advantages of our DBx
system which address the shortfalls of central labs, STAT labs and point of care
instruments.
    

         Critical Care Units
         

   
         Critical care units include intensive care units, coronary care units,
surgical suites and emergency departments. Quantech's DBx system will first be
marketed to emergency departments. Most tests conducted in the emergency
department are required STAT (urgent) and are processed 24 hours a day. Tests
processed in a STAT manner significantly increase cost because hospitals must
staff laboratories around the clock, use sophisticated technology and respond to
urgent and critical patient needs, all without the large test volumes that allow
them to spread the operating and capital costs across a large number of tests.
The solution to this difficulty and expense is to bring a single system designed
to conduct many STAT tests to the patient site in a manner that will provide
cost-effective test results promptly and accurately, without requiring much
space or personnel training. Tests typically required on an urgent basis by an
emergency department include:
    

   
     o Heart Attack (cardiac marker panel consisting of CK-MB, troponin I, 
       myoglobin)
     o Pregnancy (hCG)
     o White Blood Count panel (count with absolute neutrophils, Hct and Hgh)
     o Coagulation
     o Therapeutic Drug Monitoring (Digoxin, Theophylline)
     o Drugs of Abuse (e.g., Cocaine, Marijuana)
     o Electrolytes (not blood gases which are performed by pulse oximetry in 
       emergency department)
     o Amylase
     o Liver Enzymes
     o Bun/Creatinine
    

   
         Quantech will introduce its DBx system with at least a cardiac panel to
test for heart attacks and a pregnancy test. As discussed below, these tests
provide a significant market. Quantech will expand the number of tests the DBx
can perform beyond its first tests by adding the additional STAT tests required
by the emergency department. Because no other system known to Quantech can
provide the range of STAT tests required by the emergency department, Quantech
believes it can make substantial market penetration. Since the needs of other
critical care units are similar to those tests required by the emergency
department, Quantech anticipates that growth into these other areas will be
evolutionary.
    

   
         Heart Attacks. Tests for heart attacks (cardiac markers) are needed to
triage and treat individuals that arrive at the emergency department with chest
pain. Hospitals are aware of a need for more rapid heart attack testing and in
response have started to establish chest pain centers in emergency departments
for triaging patients. Lacking, however, are whole blood, cost effective, rapid
heart attack test results. We have chosen a panel of three heart attack tests
for the initial launch of our DBx system because of the need, reimbursement and
volume these tests represent.
    

   
         During a heart attack, certain proteins, or cardiac markers, are
released from the damaged heart muscle into the blood stream as a result of
    

<PAGE>

   
damage to the muscle. These cardiac markers are important to help to identify
patients who have suffered a heart attack. Cardiac markers are in varying
concentrations and consist of CK-MB, troponin I, myosin light chain and
myoglobin. Myoglobin is the first protein that can be detected and the first to
leave the body. CK-MB and troponin I appear later but stay in the body longer
and are more specific to cardiac damage. Therefore, combinations of these
markers are used to cover the required time frames.
    

   
         Tests for cardiac markers are most useful if they can be performed in
under twenty minutes. However, most of the existing tests require a central
laboratory system that may delay the results beyond their effective need.
Quantech's system is designed to provide emergency personnel with the ability to
receive test results in 10 to 20 minutes.
    

   
         An estimated 6 million patients are evaluated for chest pain annually
in the United States with approximately 3 million admitted to an intensive care
unit for further evaluation. Of those admitted, only 30% are subsequently
considered to have actually had a heart attack. Assuming an average cost of
$3,000 per admission, this represents a total expenditure of $6 billion annually
on patients who did not have a heart attack. This also does not take into
account that 2-8% of patients with acute chest pain that are released from the
emergency department without treatment subsequently have a heart attack
resulting in death or cardiac damage. These misdiagnoses represent greater than
20% of the malpractice dollars awarded in the field of emergency medicine.
    

   
         The high cost of admission and malpractice claims as well as the
introduction of new heart attack treatments have necessitated the development of
a method to make a rapid definitive diagnosis of chest pain. In the last 10
years, substantial progress has been made in thrombolytic therapy. If the
therapy is started within four to six hours of the onset of a heart attack, it
can dissolve the blood clot, clear arteries and save heart muscle tissue.
Because these therapies are expensive and present undesirable side effects
(e.g., allergic reactions, bleeding) if the patient has not suffered a heart
attack, rapid accurate testing for heart attacks is very important.
    

   
         Pregnancy. Every woman of child bearing age who enters the emergency
department and requires a procedure that could injure a fetus (e.g., x-ray or
drugs) should have a pregnancy test. Because of the delays in obtaining tests
from the central or STAT lab, many women are treated without the physician
receiving the results of the pregnancy test. Malpractice claims in this area are
second only to claims involving misdiagnoses of heart attacks. A rapid pregnancy
test is also important for treatment of ectopic pregnancies (gestation outside
of uterus, often in fallopian tube). Ectopic pregnancy is a leading cause of
abdominal pain for women going to the emergency department. Our DBx system will
have a whole blood quantitative test for the pregnancy marker hCG.
    

Sales and Marketing

         General

   
         The United States emergency department testing market is highly
concentrated. There are 223 high volume trauma centers in the United States that
each see more than 100,000 patients per year. Approximately 2,200 emergency
departments represent over 75% of the STAT testing market. Additionally, the
majority of hospitals belong to a small number of buying groups such as
Columbia/HCA and the Voluntary Hospital Association of America Inc. (VHA).
    

<PAGE>

   
         Quantech will form a strategic marketing group of approximately three
persons who are familiar with emergency department routines and needs and have
prior diagnostic sales experience. Initially, this marketing group will begin
creating awareness of Quantech and its DBx system. It is intended that Quantech
will engage a strategic distribution partner with a presence in diagnostic
testing to market its products in the United States. If a strategic distribution
partner is engaged, the marketing group will support this distribution partner
and maintain contact with customers to help Quantech to monitor the market for
future products.
    

   
         If an appropriate distribution partner cannot be engaged, then the
marketing group will focus on sales of the system to the highest volume
emergency departments. Because of the small number of emergency departments in
the United States, and the large amount of revenue that can be provided by each
one, Quantech believes that a small focused sales effort will enable it to
effectively penetrate the emergency department STAT testing market. Initially,
this direct sales group would total six persons and be increased as Quantech
expanded beyond the high volume trauma centers.
    

   
         Quantech will maintain a support staff to provide 24 hour product
service both in the interpretation of results and the use of the system, as well
as emergency shipping. There will be no field service. Faulty instruments will
be replaced in the event of failure.
    

         Clients

   
         The purchasing decision for diagnostic testing equipment is in the
hands of the laboratory manager, although the end user of the Quantech DBx
system will be emergency department personnel. Under CLIA regulation, the
laboratory is responsible for training, instrument calibration and quality
assurance of testing systems. As such, the laboratory will want a STAT testing
instrument to have the following features:
    

   
     o Comparable performance to central laboratory instrument with 
       similar results 
     o One (maximum of two) instruments for emergency department STAT test needs
     o Full-time, bi-directional laboratory information system computer
       interface with information automatically downloaded to laboratory
       information system
     o Automated user/patient/test/quality control information input 
     o User ID and lockout capability by laboratory 
     o Minimum user training o Physically robust - large enough so it does 
       not get stolen or dropped 
     o Costs comparable to central lab STAT tests and less than STAT lab tests
    

   
         Emergency department personnel as the ultimate users must also accept
any system that will be used for their STAT testing needs. Although in many
instances they cannot buy a testing system without laboratory approval, they are
capable of keeping a system from being purchased. A system that is acceptable to
the emergency department must provide the following features, some of which
coincide with the demands of the laboratory:
    

   
     o Comparable performance to central laboratory instrument with 
       similar results 
     o Rapid turnaround time (less than 20 minutes) 
    

<PAGE>

   
     o One (maximum of two) instruments for emergency department STAT 
       testing needs 
     o Whole blood, closed collection tube sampling and transfer 
     o Automatic laboratory information system download 
     o User friendly - minimum training and time at instrument 
     o High reliability and large enough to locate and not be stolen 
       or misplaced
    

   
         To achieve market penetration of its DBx system, Quantech's marketing
strategy will be focused on achieving the acceptance of both laboratory and
emergency department personnel. Testing systems to date have been unable to meet
the needs of both groups because of technology limitations. Quantech's DBx
system is designed to meet the requirements of both groups by incorporating all
of the required features into a single instrument.
    

   
         International
    

         

   
         Shortly after the launch of the DBx in the United States, Quantech
intends to begin sales in western Europe and, after receipt of appropriate
approvals, in Japan. These markets are similar to the United States in both the
type of STAT testing required and concentration of patients in a small number of
facilities. Quantech will manage and support international distributors, if a
strategic distribution partner is not engaged. Quantech is currently conducting
further international marketing research and has begun identifying potential
distribution partners.
    

         

Competition
   
         The majority of in-vitro medical diagnostic testing is conducted in
hospital and commercial reference laboratories. These facilities are
particularly suited for efficiently processing a large number of patient
samples. While most hospital laboratories must maintain the capability to
perform certain STAT tests on single patient sample, most of the samples handled
by central laboratories are processed so that one type of test, such as
pregnancy tests, are all run at one time or in batches. The competitors for this
market have addressed these laboratories' needs for high test throughput, low
reagent cost and low labor cost by developing automated systems. STAT labs have
been developed to address the needs of STAT testing and generally use the same
instrumentation found in the central laboratory. These laboratory systems are
generally complex and expensive, incorporating designs appropriate to the
central laboratories they serve which employ skilled operators who are expected
to perform sample preparation, system calibration and basic instrument
maintenance.
    

   
         Both the health care providers and their suppliers are heavily
committed to the current central/STAT laboratory testing system model. The
laboratories are constrained by their organization structure, their substantial
capital investment in instrumentation and the task of processing a large number
of routine non-STAT tests. The suppliers' corporate infrastructures, marketing
and sales organizations, research and development activities and production
capabilities are committed to this market. As a result, hospitals may maintain
their established means of having testing performed.
    

   
         There is a significant number of companies serving this central
clinical laboratory market. Most of them compete in only one or two segments of
the overall market. Abbott Laboratories, Roche Diagnostics, and Johnson &
Johnson are notable exceptions. These companies have achieved their broad market
    

<PAGE>

   
penetration by developing several technologies, each targeted for the specific
needs of a market segment and focusing their marketing, distribution and sales
activities on the central laboratory. The DBx in general must compete with
central and /or STAT laboratory testing systems to gain market share and, as a
result, Quantech will meet with competition from these companies in both sales
of the DBx system and the individual tests to be provided on the DBx.
    

   
         There is significant new product activity in certain areas of critical
care STAT testing. Point of care testing systems are addressing limited testing
areas such as coagulation, blood gas and basic chemistry including electrolytes.
Two such point of care systems, i-STAT Corp. and Diametrics Medical, which
market biosensor testing instruments capable of determining blood gas and
electrolyte levels have become recognized point of care testing systems.
Quantech does not believe current products of i-STAT or Diametrics are capable,
however, of providing the breadth of tests and features required by the
emergency department.
    

   
         With respect to testing for cardiac markers to diagnose a heart attack,
most testing is done in the hospital central and STAT labs with test result
turnaround times of more than 45 minutes. Quantech is aware of only a limited
number of companies that provide rapid testing for heart attacks. Of such
companies, Spectral Diagnostics Limited, a Canadian company, markets a manual
method available for certain heart attack tests. Roche Diagnostics markets a
manual test for the heart attack marker troponin I. As configured Spectral's and
Roche's heart attack tests can provide only yes/no results instead of
quantitative results such as those provided by central laboratory systems.
Biosite Diagnostics has introduced an instrument and tests for heart attacks but
the extent of sales activity is unclear. Quantech believes that Biosite's system
is not able to provide the number of tests and other STAT testing requirements
expected to be available on the DBx. Limitation of the tests that competitors'
system can perform provides Quantech a competitive advantage because the DBx is
expected to provide a large number of different tests.
    

         

   
         All of the industry leaders, and many of the other companies
participating in the diagnostic testing market, have substantially greater
resources than those available to Quantech, including, but not limited to,
financial resources and skilled personnel. However, Quantech believes the DBx
provides a product that is currently lacking for the critical care STAT testing
market. There can be no assurance that current or future companies will not
invent systems that will have broad testing capabilities and features like those
expected in the DBx. If Quantech is able to launch its system, no assurance
exists that competitive pressures will not negatively affect its pricing of both
the DBx instrument and the individual test cartridges.
    

The Technology

   
         The DBx is a biosensor that uses Quantech's proprietary surface plasmon
resonance based technology as its core. A biosensor is an analytical device that
combines a biological sensing or detection element with a suitable transducer
that converts biochemical activity into a measurable form of energy. A
biosensor's input is a specific biological event. Its output is a measurable
signal that corresponds to the input.
    

         

   
         Surface plasmon resonance is an optical-electrical phenomenon involving
the interaction of light with the electrons of a metal. The optical-electrical
basis of SPR is the transfer of the energy carried by photons of light to a
group of electrons (a plasmon) at the surface of a metal. Quantech's SPR sensor
    

<PAGE>

   
is a disposable cartridge composed of a plastic base with a fine grating molded
into its surface. The grating is coated with a very thin layer of gold. Gold is
used because it does not oxidize like other metals which can affect chemistry
binding. The gold is subsequently coated with binding molecules. The binding
molecules may be antibodies, DNA probes, enzymes or other reagents chosen
because they react exclusively with a specific analyte. The analyte is the
substance being measured, such as a heart attack marker, and defines the test to
be done.
    

   
         The coated metal surface interacts with light at a characteristic
resonant wavelength that depends upon the molecular composition at the metal's
surface. When the coated metal is exposed to a sample that contains the analyte
being tested, the analyte becomes bound to the metal through its specific
interaction with the binding molecules. As an analyte is bound, the composition
at the surface changes and consequently the resonant wavelength shifts. The
magnitude of the change in the resonant wavelength is proportional to the amount
of binding that takes place, which is proportional to the concentration of the
analyte in the sample.
    

   
         Quantech's SPR biosensor combines the strengths of biology and physics
into a single entity. Applications of SPR that have been reported in the
scientific literature or explored by Quantech include immunoassays for cardiac
markers, hormones, drugs, viruses and bacteria, quantitation of anesthetic
gases, and DNA binding assays. Quantech's SPR biosensor technology thus
represents a simple, unified platform that is capable of performing a wide range
of diagnostic tests. SPR is also a valuable research tool that Quantech expects
will allow it to quickly and efficiently develop further tests for its system.
    

Manufacturing

   
         The DBx is comprised of an instrument and disposable test cartridges.
The instrument consists of electronics and optics and does not require
complicated assembly procedures. Production of the instrument will be performed
by a contract manufacturer pursuant to quality standards set by Quantech. The
contract supplier has not yet been selected. Quantech will take delivery of the
instrument, perform final quality inspection and inventory the instrument for
final shipment.
    

   
         Quantech's test cartridge consists of two parts, the sensor grating
piece with the metal coating and the carrier for such piece. Both the coated
sensor grating and carrier will be produced by contract suppliers according to
Quantech specifications. These pieces will be shipped to either Quantech or
another contract manufacturer to complete final manufacturing of the test
cartridge. This final manufacturing will consist of:
    

   
     o Applying the assay (chemistry) on the gold coated sensor grating; 
     o Placing the final grating piece into the carrier; 
     o Performing the final assembly; 
     o Labeling the test cartridge; and 
     o Packaging the test cartridge for final shipment.
    

Regulatory Environment

   
         Quantech believes that the products it initially proposes to
manufacture and market will be classified as medical devices and will therefore
be subject to regulation by the FDA and, in some instances, by foreign
    

<PAGE>

   
government authorities. Manufacturers of medical devices must comply with
certain United States regulations governing the testing, manufacturing and
packaging of medical devices. Medical devices are subject to different levels of
testing and review and may be subject to periodic inspection, without warning,
to ensure compliance. Comparable agencies in certain states and foreign
countries will also regulate Quantech's activities. Quantech's products could be
subject to recall by the FDA or Quantech itself, if it appears that the products
and their use do not conform to regulations.
    

   
         Generally, medical devices intended for human use that are to be
marketed in the United States are placed in one of three regulatory
classifications depending upon the degree of testing and review to which the
device will be subject. Quantech expects that its products will not be subjected
to the highest level of scrutiny because they do not come into contact directly
with a living human being. Specifically, the DBx would be classified as either
Class I or Class II devices as distinguished from implantable devices, which are
classified as Class III devices.
    

   
         Quantech believes that premarket clearance can be obtained for its
initial system and tests through submission to the FDA of a "510(k) premarket
notification" that demonstrates the product's substantial equivalence to another
device legally marketed pursuant to 510(k) premarket notification clearance. The
FDA may also require, in connection with such notification, that it be provided
with the test results supporting this claim and demonstrating the safety and
efficacy of the device. Under certain circumstances, such clinical data can be
obtained only after submitting to the FDA an application for an investigational
device exemption.
    

   
         For new products that are not considered to be "substantially
equivalent" to an existing device, two levels of FDA approval will probably be
required before marketing in the United States can begin. First, the FDA and
participating medical institutions must approve Quantech's application for an
investigational device exemption, permitting clinical evaluations of the product
utilizing human samples under controlled experimental conditions. Second, the
FDA must grant to Quantech a premarket approval, which is granted if the FDA
finds that the product complies with all regulations and manufacturing
standards. In addition, the FDA may require further clinical evaluation of the
product, or it may grant a premarket approval but restrict the number of devices
distributed or require additional patient follow-up for an indefinite period of
time. Completion of this process could take up to 12 months and involve
significant costs.
    

   
         Quantech believes it is unlikely that it will be required to obtain FDA
premarket approval with respect to any of its currently proposed products,
except where mandated by the FDA such as HIV, cancer and hepatitis detection
tests. Any claims of panel diagnostics are subject to a premarket approval
procedure. Quantech anticipates that it will make claims in reference to its
heart attack tests. These claims will be made after the heart attack test is
marketed with only single claim implications. Accordingly, the heart attack test
should not be delayed in its initial introduction. If FDA premarket approval is
required for Quantech's initial system and heart attack tests, introduction of
the DBx would be significantly delayed, which could have a material adverse
effect on Quantech, although preliminary indications from the FDA are consistent
with a 510(k) filing.
    

   
         For products subject to either 510(k) premarket notification or
premarket approval regulations, the FDA requires that Quantech conduct any
required studies following its guidelines known as Good Clinical Practices and
Good Laboratory Practices. Also, the manufacture of products subject to 510(k)
premarket notification or premarket approval regulations both must be in
accordance with current FDA regulations known as Good Manufacturing Practices.
    

<PAGE>

   
         Sales of medical devices outside the United States are subject to
foreign regulatory requirements. Compliance with ISO 9000 standards and receipt
of CE mark certification will be required for products sold in the European
Union. Quantech's products will be manufactured according to ISO 9001 and EN
46001 quality standards and Quantech expects to be able to apply the CE mark to
its products. In addition, international sales of medical devices manufactured
in the United States but not approved by the FDA for distribution in the United
States are subject to FDA export requirements. Under these requirements,
Quantech must assure that the product is not in conflict with the laws of the
country for which it is intended for export, in addition to complying with the
other requirements of Section 801(e) of the United States Food, Drug and
Cosmetic Act. No regulatory clearances have yet been obtained in any country
other the United States and there is no assurance that any will be obtained.
Further, regulations and standards are subject to frequent changes. If
regulatory clearances are not obtained, compliance with changes in regulations
or standards are not met or our manufacturing facilities and those of our
contract manufacturers are in violation of applicable regulations, the sale of
the DBx could be materially adversely affected.
    

   
         Specific requirements demanded of a laboratory depend upon the
complexity of the test performed. Regulations under the Clinical Laboratory
Improvement Act of 1988 establish the following three categories of laboratory
tests:
    
         (1) tests that require little or no operator skill which allows for a
             waiver of the regulations; 
         (2) tests of moderate complexity; and 
         (3) highly complex tests which require significant operator skill or
             training.

   
         Regulatory requirements become increasingly stringent as the complexity
of the test rises. All laboratories performing tests of moderate or high
complexity must obtain either a registration certificate or a certificate of
accreditation from the Health Care Financing Administration or an organization
to whom HCFA has delegated such authority. HCFA has allowed electronic controls
for some point of care instruments to serve the function of daily quality
control performance to allow non-laboratory personnel to run such point of care
testing systems. The tests to be performed by the DBx are initially expected to
be of moderate complexity (class 2). Similar point of care systems that are
presently on the market are classified in this manner. In practical terms,
performing a test of moderate complexity means that the individual supervising
the test, i.e. the physician, pathologist or laboratory director, must be
well-educated and well-trained, but the individual operating the machine
requires no formal laboratory education and only task-specific training.
Quantech may, but has not yet, applied for the waiver to have its DBx system
placed in class 2.
    

   
         Quantech has received FDA 510(k) premarket approval for its myoglobin
heart attack test for use in the clinical environment. It has submitted its
heart attack test for the cardiac marker CK-MB and its pregnancy test for hCG to
the FDA for similar approval. Each test for the DBx system must obtain FDA
approval. Quantech must also submit its DBx system to the FDA for approval in
both the clinical setting and point of care use. The system will be provided to
the FDA for such approvals after each stage of commercial development is
completed.

Significant Agreements

         Ares-Serono License

   
         Quantech has acquired from Ares-Serono at a total cost of $3.4 million
a worldwide exclusive license to certain patents, proprietary information and
associated hardware (e.g. molds, test rigs, prototypes) related to Quantech's
SPR technology. The Ares Serono license calls for an ongoing royalty of 6
percent on all products utilizing the SPR technology which are sold by Quantech.
If Quantech sublicenses the technology, Quantech will pay a royalty of 15
percent of all revenues received by Quantech under any sublicense. Quantech has
paid $1,150,000 in minimum royalties to date and must make an additional payment
of $150,000 on December 31, 1999. If such payment is not made, Ares-Serono has
the right to cause a reversion to it of a royalty-free license, thereby
depriving Quantech of its exclusive rights under the Ares Serono license. The
obligations of Quantech to pay royalties terminate when the total royalty
payments reach a gross amount of $18 million. After such total payments,
Quantech's rights in the licensed SPR technology continue in perpetuity with no
further obligations to Ares-Serono.
    

   
         Ares-Serono specifically reserved, and did not license to Quantech, any
rights with or otherwise integrated with certain fluorescence capillary fill
device technology. Quantech believes that such limitation does not materially
impact the value of the Ares Serono license given Quantech's current plan of
commercialization. In addition, the Ares Serono license is subject to the
contingent right of PA Technology, a U.K. corporation, to request a grant of a
non-exclusive royalty-free license to exploit certain rights in the SPR
technology for applications outside the field of the commercial interests of
Quantech.
    

   
         The Perkin-Elmer Corporation Agreement
    

   
         Quantech and The Perkin-Elmer Corporation, a leading supplier of life
science systems and analytical instruments, are parties to a technology and
development agreement. Such agreement provides Perkin-Elmer with exclusive
licenses to certain Quantech technology for use outside of medical diagnostics
and co-exclusive rights to nucleic acid medical diagnostics. Perkin-Elmer,
pursuant to the agreement, provides technical assistance related to Quantech's
medical diagnostic system and future royalty payments if Perkin-Elmer sells
products using Quantech's technology.
    

         The technical assistance provided by Perkin-Elmer covers many areas
including math, software, system hardware, optics, chemistry, optical molding,
microfluidics, mechanical engineering, environmental and regulatory performance
and value engineering. Four phases of assistance have been established with a
reduction in Perkin-Elmer's royalty each time a phase is completed. Phase I and
II have been completed setting the royalty at 8% of gross sales of Perkin-Elmer
products which include Quantech technology. If all phases are met, the royalty
will be set at 6% of gross sales. Minimum royalties of $500,000 per year begin
in December of 2000 and expire in conjunction with the related patents,
provided, however, that if Perkin-Elmer does not proceed to commercialize the
licensed SPR technology prior to such date all rights revert back to Quantech.

         Quantech granted to Perkin-Elmer in December 1997 a warrant to purchase
1.4 million shares of Quantech Common Stock. The warrant expires in December

<PAGE>

2002 and is immediately exercisable. The exercise price of the warrant is 95% of
the average market price of Quantech's Common Stock for the 25 days prior to the
date Perkin-Elmer provides notice to Quantech of its intent to exercise the
warrant.

   
         Quantech, pursuant to an exclusive license agreement with Perkin-Elmer,
has licensed Perkin-Elmer technology that provides a large density, high
throughput diagnostic testing capacity for Quantech's SPR technology in medical
diagnostics other than nucleic acid testing. Through the optical and chemistry
deposition advancements made by Perkin-Elmer, they are able to read up to 100
test areas on a single 1 cm by 1 cm slide and plan to expand this capacity.
Quantech believes such two dimensional array capability, as now used in genomic
screening research, should allow Quantech to expand the DBx upstream from the
critical care area to the central laboratory. Vertical expansion to intensive
care units, surgical suites, doctor offices and home testings should also be
possible. Future generations of Quantech's current DBx system are also expected
to benefit from the Perkin-Elmer technology by reducing the number of unique
test cartridges needed to perform the same number of tests which reduces
inventory requirements and manufacturing costs.
    

         The royalty to be paid by Quantech will be 8% of gross sales of
Quantech products which include the Perkin-Elmer technology. Minimum royalties
to Perkin-Elmer of $500,000 per year begin in December of 2000, provided,
however, that if Quantech does not proceed to commercialize the SPR technology
licensed from Perkin-Elmer prior to such date, all rights revert back to
Perkin-Elmer. The Perkin-Elmer technology will not be initially incorporated
into the DBx system.

Patents and Proprietary Rights

   
         The Ares Serono license covers a total of eight patents. Some of these
patents relate to the optics, mirrors, light refraction and calibration of the
SPR instrument. The remaining patents are on the grating, optics enhancement of
the disposals, sensitivity of the chemistry on the disposable, attachment of the
assay reagents to the disposal grating and features of the prototype instrument.
The chart below provides a listing of the patents and their status.

(1)    The shares represented for Mr. McKiel were granted as warrants to
       purchase Common Stock and not options. As such, these shares are not
       included in Quantech's Nonqualified Stock Option Plan described below.
(2)    Value based on market value of Quantech's Common Stock on June 30, 1998 
       ($3.25 per share closing price) less the exercise price.
    

   
         Election of Officers and Directors; Committees of the Board of
Directors. Executive officers of Quantech are elected by the board of directors
on an annual basis and serve at the discretion of the board of directors.
Quantech's board of directors is divided into three classes with each class
being elected for a term of three years after their initial term is completed.
Quantech's directors hold office until their term has expired and their
successors have been elected and qualified.
    

   
         Quantech's board of directors has established two committees. Our audit
committee has the responsibility of selecting Quantech's independent auditors
and communicating with such auditors on matters of auditing and accounting. Our
audit committee is comprised of directors Perkins, Lyons and Strickland with Mr.
Strickland as Chairman. Our compensation committee has the responsibility of
reviewing on an annual basis all officer compensation and administering any
employee options and plans related thereto. Our compensation committee is also
comprised of directors Perkins, Lyons and Strickland with Mr. Lyons as Chairman.
    

   
         Employment Agreements. Each of Messrs. Case and Freitag has employment
contracts. Both contracts allow for termination at-will by Quantech. Pursuant to
Mr. Cases' contract he is entitled to a lump-sum payment of $150,000 if his
employment is terminated as a result of a sale of substantially all of the
assets of Quantech or a change in the control of more than 50% of Quantech's
capital stock pursuant to a single transaction or a series of transactions by
the same acquiring party. In the event Quantech terminates Mr. Freitag for any
reason other than for "cause" he is entitled to six months base salary and
bonus.
    

   
         Certain Transactions. In March 1998, Quantech issued warrants to
purchase 60,000 and 15,000 shares of its Common Stock to James F. Lyons and
Edward E. Strickland, respectively, directors of Quantech, as compensation for
the guarantee of a $500,000 bank loan to Quantech. The warrants have an exercise
price of $0.75. The amount under such loan was increased by $250,000 in August
and such directors received additional options in September to purchase an
aggregate of 75,000 shares of Quantech's Common Stock at $1.13 per share for
    

<PAGE>

   
their extension of the guarantee to this amount. In April 1998, Quantech issued
a warrant to purchase 2,500 shares of its Common Stock to Gregory G. Freitag,
Quantech's COO and CFO, as compensation for providing short term loans to
Quantech on several occasions during 1997 and 1998. The warrant has an exercise
price of $1.49.
    

   
         Stock Options. In April 1998, Quantech's board of directors adopted the
1998 Stock Option Plan and reserved 2,000,000 shares for issuance thereunder. If
any options granted under the 1998 option plan expire or are terminated prior to
being exercised in full, then the unexercised portion of such options will once
again be available for additional option grants. Options to purchase 984,850
shares of Quantech's Common Stock have been issued pursuant to the 1998 option
plan.
    

   
         The purpose of the 1998 option plan is to promote the success of
Quantech and its subsidiaries by facilitating the retention of competent
personnel and by furnishing incentive to officers, directors, employees,
consultants, and advisors upon whose efforts the success of Quantech will depend
to a large degree.
    

   
         Under the 1998 option plan, all employees, officers and directors
(including non-employee directors) of Quantech or a subsidiary, and consultants
and advisors who perform bona fide services for Quantech or a subsidiary,
provided such services are not in connection with the offer or sale of
securities in a capital raising transaction, are eligible to receive stock
options. It is the intention of Quantech to grant options which qualify as
incentive stock options under section 422 of the Internal Revenue Code, as well
as nonqualified stock options. The 1998 option plan is administered by the board
of directors or by a committee appointed by the board which selects the
individuals to whom options will be granted, the number of shares subject to
each option and the exercise price, terms and conditions of each option.
    

   
         The exercise price for incentive stock options cannot be less than 100%
of the per share fair market value of Quantech Common Stock on the date the
option is granted. In the case of incentive stock options granted to holders of
more than 10% of the voting power of Quantech securities, not less than 110% of
such fair market value. The term of an option cannot exceed 10 years, and the
term of an incentive stock option granted to a holder of more than 10% of the
voting power of Quantech cannot exceed five years. The exercise price for
nonqualified stock options is generally 100% of the per share fair market value
of the Common Stock on the date the option is granted unless otherwise
determined by the committee, provided that the exercise price is not less than
85% of the per share fair market value of the Common Stock on the date granted.
    

   
         Non-employee directors of Quantech are granted upon election an option
to purchase 10,000 shares of Common Stock at a price per share equal to 100% of
the fair market value of the Common Stock on such date. One-third of such
options are exercisable immediately, with one-third becoming exercisable on each
of the second and third anniversaries of the date of grant. After each
stockholders meeting, if the director is re-elected or his term of office
continues after such stockholders meeting, each non-employee director is granted
an option to purchase 2,500 shares of the Common Stock at an exercise price per
share equal to 100% of the fair market value of the Common Stock on such date.
These options are immediately exercisable.
    

   
         On September 3, 1996, Quantech's board of directors adopted the
Quantech Ltd. Nonqualified Stock Option Plan. The 1996 option plan provides for
the granting of nonqualified options to purchase Common Stock of Quantech to
employees, directors and members of Quantech's scientific advisory board. A
    

<PAGE>

   
total of 465,750 shares of Quantech's Common Stock have been reserved for
issuance upon exercise of options granted under the 1996 option plan.
Outstanding options for the purchase of up to 465,750 shares of Quantech Common
Stock have been granted under the 1996 option plan of which 427,418 have vested.
Quantech's compensation committee has complete discretion to determine the
persons to whom options are granted under the 1996 plan and to set the terms of
such options including, but not limited to, terms relating to price (which
generally will be the fair market value of Quantech's Common Stock on the date
of grant), duration, vesting, termination and the number of shares subject to
such option. The 1996 option plan will continue for an indefinite period until
terminated by the board of directors or compensation committee. No additional
options will be granted under 1996 option plan.
    

   
                       PRINCIPAL AND SELLING STOCKHOLDERS
    

   
         The following table provides information as of December 31, 1998
concerning the beneficial ownership of Quantech's Common Stock by (i) each
director, (ii) each executive officer named in the summary compensation table
above, (iii) each stockholder known by Quantech to be the beneficial owner of
more than 5% of its outstanding Common Stock (iv) the directors and officers as
a group and (v) each selling stockholder. Except as otherwise indicated, the
persons named in the table have sole voting and investing power with respect to
all shares of Common Stock owned by them.
    

   
         Under the rules of the Securities and Exchange Commission, shares not
actually outstanding are deemed to be beneficially owned by an individual if
such individual has the right to acquire the shares within 60 days of December
31, 1998. Pursuant to such rules, shares deemed beneficially owned by virtue of
an individual's right to acquire them are also treated as outstanding when
calculating the percent of class owned by such individual and when determining
the percent owned by any group in which the individual is included. Ownership
percentages less than 1.0% are marked with an asterisk.

<PAGE>


                            DESCRIPTION OF SECURITIES

General

   
         Quantech's articles of incorporation authorize the issuance of up to
75,000,000 shares, 50,000,000 shares consisting of Common Stock, no par value
per share, 12,500,000 undesignated shares and 2,500,000 shares of Series A
Convertible Preferred Stock. None of the holders of any class or series of
Quantech's capital stock have preemptive rights or a right to cumulative voting.
    

Common Stock

   
         As of the date of this Prospectus, there were 2,721,534 shares of
Quantech's Common Stock issued and outstanding. Quantech's board of directors
may issue additional shares of Common Stock without the consent of the holders
of Common Stock.
    

   
         Voting Rights. Each outstanding share of Common Stock is entitled to
one vote except as may be otherwise required under the terms of the MBCA. The
holders of Common Stock do not have cumulative voting rights, which means that
the holders of more than 50% of such outstanding shares voting for the election
of directors can elect all of the directors of Quantech to be elected, if they
so choose.
    

         No Preemptive Rights. Holders of Common Stock are not entitled to any
preemptive rights.

   
         Dividends and Distributions. Holders of Common Stock are entitled to
receive such dividends as may be declared by the directors out of funds legally
available therefor and to share pro rata in any distributions to holders of
Common Stock upon liquidation or otherwise. However, Quantech has not paid cash
dividends on its Common Stock, and does not expect to pay such dividends in the
foreseeable future.
    

Series A Convertible Preferred Stock

   
         The following description of the Series A Convertible Preferred Stock
is subject to the detailed provisions contained in Quantech's articles of
incorporation and Quantech's Statement of Designation which have been filed as
Exhibit 3.1 to the Registration Statement, of which this Prospectus is a part.
    

   
         Voting Rights. Each share of Series A Convertible Preferred Stock
entitles its holder to one vote for each share of Common Stock into which such
share may be converted. Holders of Common Stock and Series A Convertible
Preferred Stock vote as a single class on all matters submitted to Quantech's
stockholders, except where the Minnesota Business Corporation Act requires
separate class voting, such as with respect to voting on a merger, exchange,
liquidation or amendment to Quantech's articles of incorporation which may
adversely affect holders of Quantech's securities.
    

   
         Furthermore, without the affirmative vote of the holders of at least a
majority of the shares of Series A Convertible Preferred Stock then outstanding,
Quantech may not:
    

<PAGE>

   
     o Alter or change the rights, preferences or privileges of the Series A
       Convertible Preferred Stock; 
     o Increase the authorized number of shares of Series A Convertible
       Preferred Stock; 
     o Issue any shares of capital stock with any preference over Series A 
       Convertible Preferred Stock as to dividends or as to distributions in 
       the event of the liquidation, dissolution or winding up of Quantech, 
       provided that such prohibition shall not prevent Quantech from issuing 
       any shares which may receive distributions in such events on a pari 
       passu basis prorated, in the event assets are insufficient to pay the 
       original purchase price of all such securities, to the original purchase 
       price of each; or
     o Declare a dividend on the Common Stock.
    

   
         Dividends. Holders of Series A Convertible Preferred Stock are not
entitled to any special dividends. Any dividends paid by Quantech, which
dividends are not anticipated, will be paid equally among holders of Common
Stock and Series A Convertible Preferred Stock.
    

   
         Liquidation Preference. In the event of the liquidation, dissolution or
winding up of Quantech, whether voluntary or involuntary, assets or surplus
funds of Quantech shall be distributed first to the holders of Series A
Convertible Preferred Stock in an amount equal to $3.00 per share, as adjusted,
next, pro rata to the holders of Common Stock in an amount equal to the per
share initial amount of paid-in capital represented by such Common Stock, and
the remainder pro rata, according to shares owned, among the holders of Series A
Convertible Preferred Stock and Common Stock treating the Series A Convertible
Preferred Stock for these purposes on an as-if-converted basis.
    

   
         Conversion of Shares. Each share of Series A Convertible Preferred
Stock is convertible, at the option of each holder, at any time into four (4)
shares of Quantech's Common Stock, subject to proportional adjustment in the
event of Quantech's payment of a stock dividend, stock split of its outstanding
shares of Common Stock, a combination of its outstanding shares of Common Stock
into a smaller number of shares, a capital reorganization or merger. There are
1,702,706 shares of Series A Convertible Preferred Stock outstanding as of March
18, 1999. Quantech has reserved a sufficient number of shares of its Common
Stock for issuance upon conversion of the Shares, which number of reserved
shares will be adjusted in the event of certain actions by Quantech so as to
maintain a level of shares of Common Stock necessary to provide for the
conversion of all of the Shares.
    

   
         Concurrently with the occurrence of the closing of an offering of
Company securities for aggregate gross proceeds of at least $5,000,000 or the
date of conversion of more than 50% of the outstanding Shares, each outstanding
share of Series A Convertible Preferred Stock shall automatically convert into
Common Stock. In addition, in the event that Quantech sells Common Stock, or
securities convertible into Common Stock with a conversion price, less than
$0.75 per share, then the number of shares of Common Stock into which the Shares
may be converted will be adjusted to a number equal to the Shares per share
liquidation preference divided by such sale or conversion price.
    

Undesignated Shares

   
         The board of directors of Quantech is authorized to establish from the
undesignated shares, by resolution adopted and filed in the manner provided by
law, one or more classes or series of shares, to designate each such class or
series (which may include, but is not limited to designation as additional
common shares), and to fix the relative rights and preferences of each such
    

<PAGE>

   
class or series, which rights and preferences may adversely affect the rights of
holders of Common Stock. None of the undesignated shares have been designated by
Quantech's board of directors.

         Quantech currently has outstanding warrants to purchase 4,805,981
shares of Common Stock at exercise prices from $.75 to $14.40 per share. The
shares issuable upon exercise of these warrants are part of the shares offered

Transfer Agent

733-1121, is the transfer agent for Quantech's Common 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 Quantech's board of directors and in the policies formulated by
the board and to discourage an unsolicited takeover of Quantech, if the board
determines that such a takeover is not in the best interests of Quantech and its
stockholders. However, these provisions could have the effect of discouraging
certain attempts to acquire Quantech which could deprive Quantech'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 Quantech (from a person other
than Quantech, and other than in connection with certain mergers and exchanges
to which Quantech 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
Quantech 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 Quantech within 30 days after the acquiring person has failed to
give a timely information statement to Quantech 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 Quantech, or any subsidiary of Quantech, with any
stockholder which purchases 10 percent or more of Quantech'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 Quantech serving before the interested stockholder's share
acquisition date.
    

Certain Limited Liability and Indemnification Provisions

   
         Quantech's restated articles of incorporation, as amended, limit the
personal liability of its directors. Specifically, directors of Quantech will
    

<PAGE>

   
not be personally liable to Quantech 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 Quantech's bylaws provides that each director, officer
and employee of Quantech shall be indemnified by Quantech in accordance with,
and to the fullest extent permissible by, applicable law. Quantech maintains an
insurance policy covering director and officer liability.
    

   
         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or controlling persons of Quantech
pursuant to the foregoing provisions, Quantech 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.
    

                              PLAN OF DISTRIBUTION

   
         Quantech is registering the shares on behalf of Quantech selling
stockholders. As used in this Prospectus, stockholders selling Quantech Common
Stock pursuant to this Prospectus includes donees and pledgees selling shares
received after the date of this Prospectus from a selling stockholder named in
this Prospectus. Upon Quantech being notified by a selling stockholder that a
donee or pledgee intends to sell more than 500 shares, a supplement to this
Prospectus will be filed. All costs, expenses and fees incurred in connection
with the registration of the shares offered hereby will be borne by Quantech.
Brokerage commissions and similar selling expenses, if any, attributable to the
sale of shares will be borne by the selling stockholders.
    

   
         Sales of shares may be effected by selling stockholders from time to
time in one or more types of transactions, including block transactions, in the
over-the-counter markets, in negotiated transactions, through put or call
options on the shares and through short sales of shares. Shares may be sold at
market prices prevailing at the time of sale or at negotiated prices. The
stockholders of Quantech selling Common Stock pursuant to this Prospectus may
effect such transactions by selling shares directly to purchasers or to or
through broker-dealers as principals or agents. Such brokers-dealers may receive
compensation in the form of discounts, concessions or commissions from the
selling stockholders and/or the purchasers of the shares. The selling
stockholders have advised Quantech that they have not entered into any
agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of their securities, nor is there an
underwriter or coordinating broker acting in connection with the proposed sale
of shares by the selling stockholders.
    

         

<PAGE>

         

   
         The selling stockholders and any broker-dealers that act in connection
with the sale of shares might be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act. Quantech has agreed to indemnify each
selling stockholder against certain liabilities, including liabilities arising
under the Securities Act. The selling stockholders may agree to indemnify any
agent, dealer or broker-dealer that participates in transactions involving sales
of the shares against certain liabilities, including liabilities arising under
the Securities Act.
    

   
         Because selling stockholders may be deemed to be "underwriters" within
the meaning of Section 2(11) of the Securities Act, the selling stockholders
will be subject to the prospectus delivery requirements of the Securities Act.
Quantech has informed the selling stockholders that the anti-manipulative
provisions of Regulation M promulgated under the Exchange Act may apply to their
sales in the market.
    

   
         Selling stockholders also may resell all or a portion of the shares
under this Prospectus in open market transactions in reliance upon Rule 144
under the Securities Act, provided they meet the criteria and conform to the
requirements of such rule.
    

   
         Upon Quantech being notified by a selling stockholder that any material
arrangement has been entered into with a broker-dealer for the sale of shares
through a block trade, special offering, exchange distribution or secondary
distribution or a purchase by a broker or dealer, a supplement to this
Prospectus will be filed, if required, pursuant to Rule 424(b) under the Act,
disclosing:
    

   
     o The name of each such selling stockholder and of the participating
       broker-dealer(s); 
     o The number of shares involved; 
     o The price at which such shares were sold; 
     o The commissions paid or discounts or concessions allowed to
       such broker-dealer(s), where applicable; 
     o That such broker-dealer(s) did not conduct any investigation to 
       verify the information set out or incorporated by reference in this 
       prospectus; and
     o Other facts material to the transaction.
    

                                  LEGAL MATTERS

         The validity of the shares offered hereby will be passed upon for
Quantech by Fredrikson & Byron, P.A.

                          INDEPENDENT AUDITOR'S REPORT

To the Stockholders and the
    Board of Directors
Quantech Ltd.
St. Paul, Minnesota

We have audited the accompanying balance sheets of Quantech Ltd. (A Development
Stage Company) as of June 30, 1997 and 1998, and the related statements of
operations, stockholders' equity (deficit), and cash flows for the years ended
June 30, 1997 and 1998. 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 Quantech Ltd. (A Development
Stage Company) as of June 30, 1997 and 1998, and the results of its operations
and its cash flows for the years ended June 30, 1997 and 1998, in conformity
with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 2 to the
financial statements, the Company is a development stage company which has
suffered significant losses from operations, requires additional financing, and
ultimately needs to continue development of its product, generate revenues, and
successfully attain profitable operations to realize the value of its license
agreement and remain a going concern. These factors raise substantial doubt
about the Company's ability to continue as a going concern. Management's plans
in regard to these matters are also described in Note 2. The financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

and 1998, is unaudited)
- -------------------------------------------------------------------------------
Note 1.  Nature of Business and Significant Accounting Policies
Nature of business: Quantech Ltd. (Quantech or the Company) was formed under the
laws of the state of Minnesota for the purpose of effecting the change in
domicile of Spectrum Diagnostics S.p.A (SDS) from Italy to the state of
Minnesota through a merger with SDS on April 14, 1993. The merger was accounted
for as if it were a pooling of interests.

The Company had no operations prior to the merger and is continuing the business
of SDS to commercialize the Surface Plasmon Resonance (SPR) technology.
Commercialization will consist of developing and introducing an instrument which
will run various tests capable of diagnosing various human health conditions and
which the Company intends to market to the world medical diagnostic industry.

A summary of the Company's significant accounting policies follows:

Cash equivalents: The Company maintains its cash in bank deposit and money
market accounts which, at times, may exceed federally insured limits. The
Company has not experienced any losses in such accounts.

Fair value of financial instruments: The following methods and assumptions were
used by the Company in estimating the fair value of each class of financial
instruments:

Cash and cash equivalents: The carrying amount approximates fair value because
of the nature or short maturity of those instruments.

Short-term debt: The fair value of the Company's short-term debt is estimated
based on interest rates for the same or similar debt having the same or similar
remaining maturities with similar risk and collateral requirements. The recorded
value of short-term debt approximates its fair value.

Prepaid product development expense: Prepaid product development expense arises
from the valuation of warrants issued to a licensee in return for technical
assistance to be rendered to the Company by the licensee over a period of
approximately two years. The expense is being recognized over this period (see
Note 4).

Other assets: The license agreement is being amortized using the straight-line
method over the remaining life of the underlying patents of 15 years (see Note
4). Costs of obtaining additional patents are capitalized and will be amortized
over their useful lives.

and 1998, is unaudited)
- -------------------------------------------------------------------------------
Note 1. Nature of Business and Significant Accounting Policies (Continued) 
The Company reviews its intangible assets periodically to determine potential
impairment by comparing the carrying value of the intangibles with expected
future net cash flows. Though the Company has had no sales to date nor an
established market for its product, it has performed market studies to determine
potential size of the market and expected acceptance of its product. This has
been the basis for the Company's expected future net cash flows. Should the sum
of the expected future net cash flows be less than the carrying value, the
Company would determine whether an impairment loss should be recognized. An
impairment loss would be measured by comparing the amount by which the carrying
value exceeds the fair value of the intangible. Fair value would be determined
based on estimated expected future discounted cash flows or appraised value. To
date, management has determined that no impairment of intangible assets exists.

Property and equipment: Property and equipment are stated at cost. Depreciation
is computed by the straight-line method over five years, or the life of the
related lease, whichever is less.

Debt discount attributable to value of conversion feature: The Company has
allocated a portion of the proceeds of its debt to a beneficial conversion
feature, measured by the intrinsic value of that feature. This amount is being
amortized to interest expense using the straight-line method over the remaining
term of the debt based on the expected conversion date (see Note 3).

Income taxes: Deferred income tax assets and liabilities are computed annually
for differences between the financial statement and tax basis of assets and
liabilities that will result in taxable or deductible amounts in the future
based on enacted tax laws and rates applicable to the periods in which the
differences are expected to affect taxable income. Valuation allowances are
established when necessary to reduce deferred tax assets to the amount expected
to be realized. Income tax expense is the tax payable or refundable for the
period plus or minus the change during the period in deferred tax assets and
liabilities.

Research and development: The Company contracts with certain outside parties for
the design and development of its product in addition to conducting its own
research and development. Research and development costs are charged to expense
as incurred.

Loss per common share: The FASB has issued Statement No. 128, Earnings Per
Share, which supersedes APB Opinion No. 15. Statement No. 128 requires the
presentation of earnings per share by all entities that have common stock or
potential common stock, such as options, warrants, and convertible securities,
outstanding that trade in a public market. Those entities that have only common
stock outstanding are required to present basic earnings per share amounts. All
other entities are required to present basic and diluted per share amounts.
Diluted per share amounts assume the conversion, exercise, or issuance of all
potential common stock instruments unless the effect is to reduce the loss or
increase the income per common share from continuing operations.

(Information applicable to the six-month periods ended December 31, 1997

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

Note 1. Nature of Business and Significant Accounting Policies (Continued) 
The Company has granted options and warrants to purchase shares of common stock
at various amounts per share (see Note 6). Those options and warrants were not
included in the computation of diluted earnings per share because the Company
has incurred losses in all periods. The inclusion of potential common shares in
the calculation of diluted loss per share would have an antidilutive effect.
Therefore, basic and diluted loss per share amounts are the same in each period
presented.

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. Actual results could differ from those estimates.

Comprehensive income: The FASB has issued Statement No. 130, Reporting
Comprehensive Income, effective for fiscal years beginning after December 15,
1997. Statement No. 130 requires reporting items which are components of other
comprehensive income, such as foreign currency items and unrealized gains and
losses on certain investments in debt and equity securities. The Company will
adopt this statement in the fiscal year ending June 30, 1999. However, it is not
expected to have an effect on the presentation of the Company's financial
statements.

Segments: The FASB has issued Statement No. 131, Disclosures About Segments of
an Enterprise and Related Information, effective for fiscal years beginning
after December 15, 1997. Statement No. 131 requires disclosure of certain
information for each reportable segment, including general information, profit
and loss information, segment assets, etc. The Company will adopt this statement
in the fiscal year ending June 30, 1999. The Company does not expect this
statement to have an effect on its financial statements.

Translation of foreign currency statements: Prior to September of 1992, the
functional and reporting currency for SDS was the Italian lira. Concurrent with
the receipt of net proceeds from its initial public offering of common stock in
the United States in September 1992, and in connection with the phase-out of its
Italian operations, the functional and reporting currency of SDS changed from
the Italian lira to the United States dollar. As a result, the cumulative
translation adjustment component of equity was eliminated in 1992.

Interim financial information (unaudited): The financial statements and notes
related thereto as of December 31, 1998, for the six-month periods ended
December 31, 1997 and 1998, and the period from September 30, 1991 (date of
inception), to December 31, 1998, are unaudited but, in the opinion of
management, include all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of the financial position and
results of operations. The operating results for the interim periods are not
indicative of the operating results to be expected for a full year or for other
interim periods. Not all disclosures required by generally accepted accounting
principles necessary for a complete presentation have been included.

- -------------------------------------------------------------------------------
Note 2.  Basis of Presentation
The Company was incorporated for the purpose of acquiring, developing, and
commercializing SPR technology for use in medical diagnostics. The Company has
had no sales, and the only revenue generated by the Company since its inception
has been interest income.

The Company is a development stage company which has suffered significant losses
from operations, requires additional financing, and ultimately needs to continue
development of its product, generate revenues, and successfully attain
profitable operations. These factors raise substantial doubt about the Company's
ability to continue as a going concern and realize the value of its assets,
including its license agreement. The financial statements do not reflect any
adjustments which might be necessary should the Company not remain a going
concern.

Without immediate funding from equity or debt financing, the Company does not
have sufficient funds to remain a going concern, or to complete commercial
development of and bring its instrument and disposables to commercial production
and realize the value of the license agreement. The Company obtained funding
through a private offering of its Series A convertible preferred stock in
November 1998 and converted notes payable, due September 30, 1998, to Series A
convertible preferred stock (see Note 10). The Company has also increased its
note payable to a bank by $250,000. In addition, the Company intends to pursue a
$5 to $7 million offering in early 1999 with terms yet to be determined. There
is no assurance that additional financing can be obtained.

Note 3.  Short-Term Debt Obligations
Short-term debt obligations as of June 30, 1997 and 1998, and December 31, 1998,
were as follows:

Note 3.     Short-Term Debt Obligations (Continued)
In April 1998, the Company completed an offering of secured promissory notes of
$1,625,150 to accredited investors and issued warrants in connection with the
sale of such notes to the investors for the purchase of 243,773 shares of common
stock. In addition, the selling agent also received warrants to purchase 10,249
shares of common stock. The notes are convertible into shares of common stock at
a price equal to the lesser of $3.53 or 80 percent of the market price of the
common stock for (i) the 20 consecutive trading days prior to the maturity date
of the notes or (ii) the price at which the transaction which triggers repayment
of the notes is completed. The warrants exercise price is calculated in the same
manner as the notes conversion price.

During May 1998, holders of the Company's convertible secured promissory notes
agreed to convert $219,300 of accrued interest in notes and extend the maturity
date of the notes to September 30, 1998, from June 1, 1998. The note holders
received additional warrants to purchase 178,618 shares of common stock in
conjunction with the agreement.

During May 1998, the Company began an offering of convertible secured promissory
notes to accredited investors. The maximum amount of notes to be issued was
$500,000. As of June 30, 1998, notes in the amount of $245,270 were issued.
Purchasers of the notes also received warrants for the purchase of 36,790 shares
of common stock. Conversion and warrant exercise terms are the same as those
discussed above.

The above warrants were valued at $943. This minimal fair value was based upon
management's determination that the effective interest rate of the debt was
determined to be equal to the market rate for similar debt instruments with
similar risk.

Subsequent to year end, the Company completed the offering by issuing an
additional $252,230 of the notes. Warrants to purchase 37,835 shares of common
stock were issued. In conjunction with this offering, the selling agent received
warrants to purchase 3,134 shares of common stock. These warrants were valued at
$76. This minimal fair value was based upon management's determination that the
effective interest rate of the debt was determined to be equal to the market
rate for debt instruments with similar risks.

Note 4.  Agreements
License agreement: The Company has a license agreement for certain patents,
proprietary information, and associated hardware related to the SPR technology.
The license calls for an ongoing royalty of 6 percent on all products utilizing
the SPR technology which are sold by the Company. In addition, if the Company
sublicenses the technology, the Company will pay a royalty of 15 percent of all
revenues received by the Company under any sublicense. If the cumulative
payments of these two royalties fail to reach at least $500,000 by December 31,
1993, $850,000 by December 31, 1995, $1,000,000 by December 31, 1997, $1,150,000
by December 31, 1998, and $1,300,000 by December 31, 1999, the licensor has the
right to deprive the Company of its exclusive rights under the license agreement
(each time one of such benchmarks is not met). As of June 30, 1998, the Company
has paid $1,000,000 of the cumulative payment. The Company has also ratably
accrued additional minimum royalty payments of $75,000 as of June 30, 1998
($112,500 as of September 30, 1998), because sales or sublicense revenues
through December 31, 1998, may not be adequate to meet the cumulative minimum
royalty payments. The Company intends to accrue $150,000 by December 31, 1998,
and continue accruing and paying minimum royalties for future periods until
royalties based on revenues exceed the minimum payment amounts.

The obligations of the Company to pay royalties terminate when the total royalty
payments reach a gross amount of $18,000,000, which amount would be increased by
$2,000,000 each time a benchmark is not met. After such date, the Company's
rights in the licensed SPR technology continue in perpetuity with no further
royalty obligations.

In September 1997, the Company entered into an agreement to purchase certain
sublicense rights that had previously been granted to an investor group which
included a shareholder of the Company. In return for these sublicense rights,
the Company issued 150,000 shares of the Company's common stock, convertible
secured promissory notes totaling $550,000, and warrants to purchase 82,500
shares of the Company's common stock. The Company has capitalized the sublicense
rights at $940,165, the amount that approximates the fair market value of the
equity and debt instruments issued as of the date of the agreement. The value
assigned to the common stock was based on the quoted market value. The values of
the convertible debt instrument and the detachable warrants were based on
similar instruments previously placed by the Company.

Technology and development agreement: During the year ended June 30, 1998, the
Company entered into a technology and development agreement with a leading
supplier of life science systems and analytical instruments, which provides
exclusive license rights to certain of the Company's technology for use outside
of medical diagnostics, and co-exclusive rights to nucleic acid medical
diagnostics. The licensee, pursuant to the agreement, is providing technical
assistance related to the Company's medical diagnostic system and will be
required to pay future royalty payments if the licensee sells products
containing the Company's technology. The royalties to be received will vary
between 6 and 12 percent, depending on the phase of assistance. When all phases
are complete, the royalty will be 6 percent. Minimum annual royalties to be paid
by the licensee will be $500,000 beginning December 2000, expiring in
conjunction with the related patents. Should the licensee fail to commercialize
the licensed technology, all rights will revert back to the Company.

Note 4. Agreements (Continued)
The licensee also received a warrant to purchase 1,400,000 shares of common
stock. The warrant expires December 2002 and is exercisable immediately. The
exercise price of the warrant is 95 percent of the average market price of the
Company's common stock for the 25 days prior to the date the licensee elects to
exercise the warrant. The warrant was valued at $230,000, based on the
difference between the quoted fair market value of the Company's stock on the
date of issuance and what the exercise price would have been on that date.

In conjunction with the above technology and development agreement, the Company
has licensed additional technology. The Company will be required to pay
royalties at 8 percent of sales on products featuring the technology. Minimum
annual royalties of $500,000 begin in December 2000, expiring in conjunction
with the related patents. Should the Company fail to commercialize the license
technology, all rights will revert back to the licensor, and future minimum
annual royalty obligations will be canceled.

Employment agreements: The Company has at-will employment agreements with its
Chief Executive Officer and Chief Financial Officer. The agreements require the
payment of one year's salary (for the chief financial officer) or $150,000 (for
the chief executive officer) if employment is terminated due to the sale of the
Company or a greater than 50 percent change in ownership. In addition, the Chief
Financial Officer is entitled to six months' salary if he is terminated without
cause.

Note 5.  Leases
The Company leases its office space under an agreement which expires February
28, 2000. Approximate minimum aggregate rental commitments under this lease are
as follows:

Years ending June 30:
1999                                     $        38,000
2000                                              26,000
                                       -------------------
                                         $        64,000
                                       ===================


Rental expense for the years ended June 30, 1997 and 1998, was approximately
$68,000 and $58,000, respectively.

Note 6.  Stockholders' Equity
Capital stock: The Company has authorized 12,500,000 of capital shares
consisting of 10,000,000 common shares and 2,500,000 undesignated shares (see
Note 10 for subsequent activity).

Reverse stock split: On June 2, 1998, the Company reduced the number of shares
outstanding in a 1-for-20 reverse stock split. All share and per share amounts
presented have been retroactively adjusted to reflect the split.

Note 6.  Stockholders' Equity  (Continued)
Par value of stock: In March 1998, the Company amended its Articles of
Incorporation to reduce the number of authorized shares from 90,000,000 to
12,500,000. In addition, the common stock was changed from $0.01 per share par
value to no par value. The cumulative amount paid in excess of the previously
stated par value has been reclassed from additional paid-in capital to common
stock on the statement of stockholders' equity (deficit) for the year ended June
30, 1998.

Options and warrants--employee grants: The Company regularly grants options to
its employees. As permitted under generally accepted accounting principles,
these grants are accounted for following APB Opinion No. 25 and related
interpretations. Accordingly, compensation cost has been recognized for those
grants whose exercise price of the grant exceeds the fair market value of the
stock on the date of grant. There was $48,000 of compensation expense recorded
for employee grants for the year ended June 30, 1997, and none recorded for the
year ended June 30, 1998, and six months ended December 31, 1998.

Options and warrants--nonemployee grants: The Company also grants options and
warrants to nonemployees for goods, services, and in conjunction with certain
agreements. These grants are accounted for under FASB Statement No. 123 based on
the grant date fair values.

Options and warrants--pro forma information: Had compensation cost for all of
the stock-based compensation grants and warrants issued been determined based on
the grant date fair values of awards, reported net loss attributable to common
stockholders and net loss per common share would have been reduced to the pro
forma amounts shown below:

</TABLE>


The above pro forma effects on net loss and net loss per share are not likely to
be representative of the effects on reported net loss for future years because
options vest over several years and additional awards generally are made each
year.

         consecutive trading days immediately preceding the date of the first
         notice of exercise of the warrant received by the Company. The exercise
         price of these warrants will change as the market value of the
         Company's common stock changes.

Note 7.  Income Taxes
The Company's income tax expense consists solely of a franchise tax in Italy
during the year ended December 31, 1992, since the Company has incurred no
United States income taxes. For United States income tax purposes, under
provisions of the Internal Revenue Code, the Company has approximately
$11,920,000 in operating loss carryforwards and $316,000 in research and
development credits at June 30, 1998, which may be used to offset otherwise
future taxable income. These carryforwards are subject to certain limitations
under the provisions of the Internal Revenue Code, Section 382, which relate to
a 50 percent change in control over a three-year period. The annual net
operating loss carryforward limitation due to Section 382 is approximately
$200,000 per year, which reduced the carryforward by $2,800,000. The Company has
"post change" carryforwards of approximately $8,888,000 that are not limited.
Further changes of control may result in the additional expiration of a portion
of the remaining carryforwards before they can be used and are also dependent
upon the Company attaining profitable operations in the future.

Loss carryforwards and credits for tax purposes, reduced by the Section 382
limitation discussed above, as of June 30, 1998, have the following expiration
dates:

                                    Net         Research and
Expiration                       Operating       Development

The income tax provision differs from the amount of income tax determined by
applying the U.S. federal income tax rate to pretax income for the years ended
June 30, 1997 and 1998, due to the valuation allowance recorded against deferred
tax assets.

Note 8.  Spectrum Diagnostics, Inc.
As a result of its merger with SDS (see Note 1), Quantech guaranteed payment of
certain liabilities. As of June 30, 1998, the Company is not aware of any
guarantees outstanding; however, the Company has recorded a liability of $19,800
for potential claims or unknown liabilities.

Note 9.  Subsequent Events
During July and August 1998, the Company issued 14,910 shares of its common
stock at prices ranging from $3.00 per share to $3.50 per share for equipment
and services rendered. In addition, 2,000 shares were issued pursuant to the
conversion of a promissory note, and 2,045 shares were issued pursuant to the
exercise of a warrant.

Note 10.  Additional Subsequent Events (Unaudited)
In September and October 1998, 3,400 and 25,000 shares of common stock,
respectively, were issued pursuant to the conversion of promissory notes. In
September and from October to December 1998, 12,557 and 6,078, respectively,

Note 10.    Additional Subsequent Events (Unaudited) (Continued)
In November 1998, the Company established Series A Preferred Stock (Series A
Stock) and designated 2,500,000 of its authorized and previously undesignated
shares as Series A Stock. The shares have no par value and a liquidation value
of $3.00 per share. Each share of Series A Stock is convertible into, and has
voting rights equal to, four shares of common stock. The Series A Stock is not
redeemable until November 5, 2003. If any time after November 5, 2003, the
Company receives a written request from the holders of at least 50 percent of
the outstanding share of Series A Stock, the Company will redeem all of the
outstanding shares by paying in cash an amount equal to the sum of the original
purchase price plus a 10 percent return per annum. Series A Stock is
automatically converted into shares of common stock if (i) the Company closes on
an equity offering of at least $5,000,000 or (ii) at least 50 percent of the
number of shares of Series A Stock that were outstanding as of November 30,
1998, have been converted or redeemed. The excess of redemption value over
carrying value will be accrued, using the interest method, over the period until
the first redemption date of November 5, 2003.

In November and December 1998, the Company sold 600,617 shares of its Series A
Stock to accredited investors at $3.00 per share and issued 1,124,715 shares of
Series A Stock pursuant to conversion of promissory notes at a conversion price
of $3.00 per share. The holders of the promissory notes also received warrants
to purchase 728,957 shares of common stock at an exercise price of $0.75. The
receipt of these warrants canceled the detachable warrants issued in conjunction
with the promissory notes. The new warrants were valued at $162,000 using the
Black-Sholes model. In conjunction with these transactions, the Company paid
commissions and expenses of $125,700 and issued warrants to purchase 176,420
shares of common stock to the selling agents, which were valued at approximately
$65,000 using the Black-Sholes model.

In November 1998, 74,052 shares of common stock were issued pursuant to
conversion of Series A Stock.

In November 1998, a warrant to purchase 1,800,000 shares of common stock was
issued in conjunction with a research and development services agreement. The
warrant is exercisable immediately at $1.10 per share and was valued at
approximately $518,000 using the Black-Sholes model. Since all of the services
under this agreement have not been rendered, the $388,500 unearned portion as of
December 31, 1998, has been recorded as contra-equity. The unearned portion will
be recognized as expense as services are rendered over the term of the
agreement. In conjunction with this agreement, warrants to purchase 144,000
shares of common stock were issued, and $190,000 in cash was paid to the
investment banking firm that arranged the transaction. These warrants were
valued at $36,000 using the Black-Sholes model.

In December 1998, the Company amended its Articles of Incorporation to increase
the number of authorized shares from 12,500,000 to 75,000,000, of which
50,000,000 is common stock, 2,500,000 is Series A Stock, and 22,500,000 is
undesignated.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 24.  Indemnification of Directors and Officers.

   
         Section 302A.521, subd. 2, of the Minnesota Statutes requires Quantech
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
Quantech, 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 Quantech, or, in the case of performance by
a director, officer or employee of Quantech 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 Quantech. In addition, Section 302A.521, subd. 3, requires payment
by Quantech, 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
Quantech are contained in Article 5 of the Restated Bylaws (Exhibit 3.2 to this
Registration Statement). Quantech maintains a director and officer liability
policy.

distribution of the securities registered hereby and do not include the

Item 28.  Undertakings.

         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 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.

<PAGE>

         The undersigned Registrant further undertakes that it will:

         (1)      file,  during any period in which it offers or sells  
                  securities,  a  post-effective  amendment to this registration
                  statement to:

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

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

                  (iii)    include any additional or changed material
                           information on the plan of distribution;

         (2)      for determining liability under the Securities Act, treat each
                  post-effective amendment as a new registration statement of
                  the securities offered, and the offering of the securities at
                  the time to be the initial bona fide offering; and

         (3)      file a  post-effective  amendment to remove from registration 
                  any of the securities that remain unsold at the end of
                  the offering.
