                               PROSPECTUS SUMMARY

     The following summary is qualified in its entirety by reference to the more
detailed information and financial statements and notes appearing elsewhere in
this Prospectus. Unless otherwise indicated, all financial and share information
set forth in this Prospectus (i) has been adjusted to reflect the conversion of
all outstanding Convertible Preferred Stock into Common Stock upon the
effectiveness or the closing of this offering, (ii) reflects a 1-for-1.313
reverse stock split of the Common Stock to be effected on July 10, 1996, (iii)
assumes an initial public offering price of $9.00 per share, the midpoint of the
range set forth on the cover page of this Prospectus, and (iv) assumes no
exercise of the Underwriters' over-allotment option. Unless the context requires
otherwise, all references in this Prospectus to "Medi-Ject" or the "Company"
refer to Medi-Ject Corporation. This Prospectus contains forward-looking
statements that involve risks and uncertainties. The Company's actual results
may differ significantly from the results discussed in the forward-looking
statements. Factors that might cause such differences include, but are not
limited to, those discussed under the heading "Risk Factors," which investors
should consider carefully.

                                  THE COMPANY

     Medi-Ject is a drug delivery company focused on developing, manufacturing
and marketing needle-free injection systems for the self-administration of a
wide range of parenteral (injectable) drugs. The Company's product, the Medi-
Jector system, is a hand-held, spring-powered device that injects drugs from a
drug-containing front-end chamber through the skin without a needle as a narrow,
high pressure stream of liquid approximately 7/1000ths of an inch in diameter.
The Medi-Jector system eliminates the need to pierce the skin with a hypodermic
needle and therefore is perceived by many people to be less threatening than
injection with a needle. Today's Medi-Jector systems are smaller, easier to use,
less expensive and more comfortable than previous needle-free injection systems.
The Company believes that the key to widespread market acceptance of its 
needle-free injection systems depends upon continued improvements in these
areas.

     The Company believes that needle-free injection systems will benefit
individuals who require self-injection by (i) eliminating the need to pierce
themselves with needles for each injection, which should lead to an increased
willingness to comply with a prescribed injection regimen and consequently
reduce health complications, (ii) providing the ability to inject themselves
discreetly and (iii) eliminating the need for special disposal of used needles.
In addition, healthcare industry providers and payors may benefit from the
decrease in long-term costs of patient care which may result from improved
patient compliance. Furthermore, pharmaceutical companies may benefit from an
increased ability to differentiate their products in the marketplace and
improved patient compliance, both of which may lead to increased sales and
larger market share.

     The Company has entered into licensing and development agreements with
multi-national pharmaceutical and medical device companies covering the design
and manufacture of customized injection systems for specific drug therapies. In
addition to agreements with pharmaceutical companies, including those with
Ferring NV, JCR Pharmaceuticals Co., Ltd., Bio-Technology General Corporation,
Schwarz Pharma AG and GeneMedicine, Inc., the Company has entered into a
strategic alliance with Becton Dickinson and Company ("Becton Dickinson"). The
goal of this alliance is the joint development and commercialization of new,
less expensive and more user friendly injectors which embody proprietary,
advanced technology. The Company will design and manufacture the injectors, and
Becton Dickinson will design and manufacture the consumable components for the
systems. Becton Dickinson has the right to market the injectors and the
consumable components worldwide for use initially with insulin and potentially
with other drugs. Medi-Ject and Becton Dickinson will collaborate on the
development and manufacture of customized versions of the system and share
revenues from sales of injectors and consumables to pharmaceutical companies and
any revenue generated from licensing milestone payments, development fees and
royalties.

     The Company's focus is on the market for the delivery of self-administered
parenteral drugs, the largest, most developed portion of which consists of the
delivery of insulin. In the United States, over 3.2 million people inject
insulin for the treatment of diabetes, resulting in an estimated 2.3 billion
injections annually, and the Company believes that the number of insulin
injections will increase with time as the result of new diabetes management
approaches which recommend more frequent use. Other parenteral drugs that are
self-administered and may be suitable for injection with the Medi-Jector system
include therapies for the treatment of multiple sclerosis, migraine headache,
growth retardation, impotence, female infertility, AIDS and hepatitis. The
Company also believes that more existing parenteral drugs will be self-
administered in the future and that additional parenteral drugs that are under
development will be deemed appropriate for self-administration.

     The Company's goal is to establish its needle-free injectors as the drug
delivery method of choice for the self-administration of a wide range of
parenteral drugs. The Company's strategic plan for accomplishing this goal
consists of (i) developing improved proprietary injection systems, (ii)
generating an income stream from consumable components, (iii) collaborating with
pharmaceutical and medical device manufacturers to leverage off of their
marketing capabilities and (iv) focusing on delivery systems for high-priced
pharmaceuticals.

     The Company's offices are located at 1840 Berkshire Lane, Minneapolis,
Minnesota 55441, and its telephone number is (612) 553-1102.  The Company was
incorporated in Minnesota in 1979.

                                  RISK FACTORS

     An investment in the shares of Common Stock offered hereby involves a high
degree of risk and immediate and substantial dilution. In evaluating an
investment in the Common Stock being offered hereby, investors should consider
carefully, among other matters, the following risk factors, as well as the other
information contained in this Prospectus.

UNCERTAINTY OF MARKET ACCEPTANCE; LIMITED CURRENT MARKET FOR NEEDLE-FREE
INJECTION SYSTEMS

     The Company's success will depend upon increasing market acceptance of its
needle-free injection systems as an alternative to needle injections. During the
approximately 15 years since their initial commercial introduction, the
Company's needle-free injection systems have had only limited success competing
with traditional needles and syringes because, the Company believes, of the
size, cost and complexity of use and maintenance of the Company's injectors and
the relatively small number of parenteral drugs that have been self-
administered. In order to increase market acceptance, the Company believes that
it must successfully develop improvements in the design and functionality of
future needle-free injection systems that will reduce their cost and increase
their appeal to users, thereby making these systems desirable despite their
premium cost over traditional disposable needles and syringes. Projected
improvements in functionality and design may not adequately address the actual
or perceived complexity of using the Company's needle-free injection systems or
adequately reduce their cost. In addition, the Company believes that its future
success is dependent upon its ability to enter into additional collaborative
agreements with drug and medical device manufacturers for the use of its needle-
free injection systems with new and existing parenteral drugs. There can be no
assurance that the Company will be successful in these efforts or that its
needle-free injection systems will ever gain sufficient market acceptance to
sustain profitable operations. See "Business--Strategy," "--Target Markets" and
"--Products and Technology."

HISTORY OF OPERATING LOSSES; UNCERTAINTY OF FUTURE PROFITABILITY

     The Company has had a history of operating losses and, at March 31, 1996,
had an accumulated shareholders' deficit of approximately $9.9 million. Net
losses for the years ended December 31, 1993, 1994 and 1995 and the three months
ended March 31, 1996 were $500,319, $1,066,462, $1,882,459 and $553,015,
respectively. The Company expects to continue to incur net losses at least
through 1997, as it introduces new and improved needle-free injection systems
while undertaking research and development, regulatory approval and commercial
introduction activities related to new uses for its needle-free injection
systems. There can be no assurance that the Company will achieve or sustain
profitability in the future. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

RISKS ASSOCIATED WITH DEVELOPING IMPROVED SYSTEMS AND NEW USES

     The Company believes that its future success is in part dependent upon the
development and commercial introduction of needle-free injection systems that
incorporate improvements in design and functionality to reduce their cost and
increase their appeal to users. In the United States, Japan and certain European
countries, the Company's needle-free Medi-Jector system has been approved only
for the injection of insulin and human growth hormone. The Company's future
success depends to a significant degree on its ability to obtain regulatory
approval for and commercialize the use of its needle-free injection systems for
other parenteral drugs. However, the Company has not yet completed research and
development work or obtained regulatory approval for such improved systems or
for use with any drugs other than insulin and human growth hormone. There can be
no assurance that any development work will ultimately be successful or that
unforeseen difficulties will not occur in research and development, clinical
testing, regulatory submissions and approval, product manufacturing and
commercial scale up, marketing, or product distribution related to any such
improved systems or new uses. Any such occurrence could materially delay the
commercialization of such improved systems or new uses or prevent their market
introduction entirely. See "--Government Regulations" and "Business."

RISKS OF RELATIONSHIP WITH BECTON DICKINSON AND COMPANY

     The Company's ability to introduce improved and less expensive needle-free
injection systems will depend in part on the success of its collaborative effort
with Becton Dickinson to develop a smaller needle-free injector with a
disposable, single-use front-end chamber. This effort is governed by the terms
of a Development and License Agreement between the Company and Becton Dickinson
(the "Becton Dickinson Agreement"), under which the Company is responsible for
developing the injector body and Becton Dickinson is responsible for developing
the front-end chamber for the system. Until January 1, 1999, Becton Dickinson
may terminate the Becton Dickinson Agreement without cause by providing six
months' written notice and after January 1, 1999, by providing 12 months'
written notice. Since the Company expects that the majority of the funding for
its development efforts on the new, smaller injector will be derived from
payments to be made by Becton Dickinson under the Becton Dickinson Agreement and
since responsibility for developing the front-end chamber lies with Becton
Dickinson, any termination of the Becton Dickinson Agreement would adversely
affect the timing and the likelihood of ultimate success of these development
efforts. In addition, under the Becton Dickinson Agreement, Medi-Ject granted
Becton Dickinson the exclusive, worldwide right to sell a proposed new injector
for use with insulin and any other injector that is not designed or calibrated
for use with a specific drug made by a specific drug company and that is
intended to be distributed primarily through pharmacies for non-professional
use. These exclusive rights will continue for a period of at least five years
from the date of the United States Food and Drug Administration (the "FDA")
marketing clearance of each such injector, and for a longer period if Becton
Dickinson meets certain minimum sales goals set in the Becton Dickinson
Agreement. During such period, the Company will not have the right to sell any
such injector independently. In addition to the systems to be sold by Becton
Dickinson, the Company and Becton Dickinson expect to enter into agreements with
third-party pharmaceutical companies, including development, supply and license
agreements, governing the development and commercial sale of needle-free
injection systems for use only with such third-party pharmaceutical company's
version of a specific drug. Furthermore, prior to developing a system for use
with any specific drug, the Company and Becton Dickinson must mutually agree on
whether or not such system will be of the type covered by Becton Dickinson's
exclusive sales rights. There can be no assurance that any such agreements will
be entered into or that the terms of any such agreements will be advantageous to
the Company. See "Business--Collaborative Agreements" and "--Products and
Technology."

DEPENDENCE ON COLLABORATIVE RELATIONSHIPS

     The Company believes that the introduction and broad acceptance of its
systems is in part dependent upon the success of its current and any future
development and licensing arrangements with pharmaceutical and medical device
companies covering the development, manufacture or use of the Medi-Jector system
with specific parenteral drug therapies. The Company anticipates, consistent
with past practice, that under these arrangements the pharmaceutical or medical
device company will assist in the development of systems for such drug therapies
and collect or sponsor the collection of the appropriate data for submission for
regulatory approval of the use of the Medi-Jector system with the licensed drug
therapy. The pharmaceutical or medical device company also will be responsible
for distribution and marketing of the systems for these drug therapies either
worldwide or in specific territories. There can be no assurance that the Company
will be successful in executing additional agreements with pharmaceutical or
medical device firms or that existing or future agreements will result in the
sale of the Company's needle-free injection systems. As a result of these
arrangements, the Company is dependent upon the development, data collection and
marketing efforts of such pharmaceutical and medical device companies. The
amount and timing of resources such pharmaceutical and medical device companies
devote to these efforts are not within the control of the Company, and such
pharmaceutical and medical device companies could make material decisions
regarding these efforts that could adversely affect the Company's future
financial condition and results of operations. In addition, factors that
adversely impact the introduction and level of sales of any drug covered by such
licensing arrangements, including competition within the pharmaceutical and
medical device industries, the timing of FDA or other approvals and intellectual
property litigation (such as that surrounding Bio-

                                       7
<PAGE>
 
Technology General Corporation's human growth hormone, which has delayed the
introduction of the use of the Medi-Jector system with human growth hormone in
the United States), will also negatively affect the Company's sales of Medi-
Jector systems for those uses. See "Business--Target Markets," "--Collaborative
Agreements," "--Products and Technology" and "--Marketing."

DEPENDENCE ON THIRD-PARTY DEVELOPMENT EFFORTS

     The Company relies heavily on outside consultants for its technology
development and engineering work, and the Company's ability to introduce new
systems and improvements to its existing systems is dependent on their efforts.
There can be no assurance that the Company's current consultants will produce
the necessary work product in a timely fashion or at all, or that the Company
could find suitable replacements if the services of such consultants were to
become unavailable. "Business--Products and Technology."

COMPETITION; RISK OF TECHNOLOGICAL OBSOLESCENCE

     In addition to competition from traditional hypodermic needles and syringes
(including syringes with hidden and sheathed needles), the Company's needle-free
injection systems also compete with other needle-free injection devices.
Currently, competition in the needle-free injection market is limited to small
companies with modest financial and other resources, but the barriers to entry
are currently low and additional competitors may enter the needle-free injection
systems market, including companies with substantially greater resources and
experience than the Company. There can be no assurance that the Company will be
able to compete effectively against its current or potential competitors in the
needle-free injection market, or that such competitors will not succeed in
developing or marketing products that will be more accepted in such market.
Competition in this market could also force the Company to reduce the prices of
its systems below currently planned levels, thereby adversely affecting the
Company's revenues and future profitability.

     In general, injection is used only with drugs for which other drug delivery
methods are not possible, in particular with biopharmaceutical proteins (such as
insulin and human growth hormone) that cannot currently be delivered
transdermally, orally or pulmonarily. Many companies, both large and small
(including Becton Dickinson), are engaged in research and development efforts on
novel techniques aimed at delivering such drugs without injection. The
successful development and commercial introduction of such a non-injection
technique would likely have a material adverse effect on the Company's business,
financial condition, results of operations and general prospects. See 
"Business--Competition."

LIMITED MANUFACTURING EXPERIENCE; RISKS ASSOCIATED WITH NEW MATERIALS, NEW
ASSEMBLY PROCEDURES AND INCREASED PRODUCTION LEVELS

     The Company's past assembly, testing and manufacturing experience has
related primarily to the assembly of products from machined stainless steel and
composite plastic components in limited quantities. The Company's planned future
needle-free injection systems necessitate significant changes and additions to
the Company's manufacturing and assembly process to accommodate new plastic
components and a new injection power source. These systems must be manufactured
in compliance with regulatory requirements, in a timely manner and in sufficient
quantities while maintaining quality and acceptable manufacturing costs. In
addition, the Company's plans call for significantly increased levels of
production and a shift to performing more manufacturing functions internally
rather than relying on third-party suppliers, which will require the Company to
expand beyond its current facilities. In the course of these changes and
additions to its manufacturing and production methods, the Company may encounter
difficulties, including problems involving yields, quality control and
assurance, product reliability, manufacturing costs, existing and new equipment,
component supplies and shortages of personnel, any of which could result in
significant delays in production. There can be no assurance that the Company
will be able successfully to plan for production and manufacture of the
Company's future needle-free injection

                                       8
<PAGE>
 
systems. Any failure to do so would negatively impact the Company's business,
financial condition and results of operations. See "Business--Manufacturing."

GOVERNMENT REGULATIONS

     Government regulation in the United States and certain foreign countries is
a significant factor in the Company's business. In the United States, the FDA
has principal jurisdiction over products that are used for human injection.
Certain clearances are required from the FDA before medical devices, such as the
Company's needle-free injection systems and their use with new drug therapies,
can be marketed. The FDA regulatory process in the United States may delay the
marketing of new systems for lengthy periods and impose substantial additional
costs. Moreover, FDA marketing clearance regulations depend heavily on
administrative interpretation, and there can be no assurance that
interpretations made by the FDA or other regulatory bodies, with possible
retroactive effect, will not adversely affect the Company. There can be no
assurance that the Company will be able to obtain clearance of any future
Company systems or any expanded uses of current or future Company systems in a
timely manner or at all. In addition, even if obtained, FDA clearances are
subject to continual review, and if the FDA believes that the Company is not in
compliance with applicable requirements, it can institute proceedings to detain
or seize the Company's systems, require a recall, suspend production,
distribution, marketing and sales, enjoin future violations and assess civil and
criminal penalties against the Company, its directors, officers or employees.
The FDA may also suspend or withdraw market approval for the Company's systems
or require the Company to repair, replace or refund the cost of any system
manufactured or distributed by the Company. The Company must also demonstrate
compliance with current Good Manufacturing Practices regarding quality control
and manufacturing procedures. Compliance with these requirements requires the
Company to expend time, resources and effort in the areas of production and
quality control for itself and for its contract manufacturers. If violations of
the applicable regulations are noted during FDA inspections, the continued
marketing of any systems manufactured by the Company may be halted or adversely
affected.

     Sales of medical devices outside the United States are subject to United
States export requirements and foreign regulatory requirements. Legal
restrictions on the sale of imported medical devices vary from country to
country. The time and requirements to obtain approval by a foreign country may
differ substantially from those required for FDA approval. There can be no
assurance that the Company will be able to obtain regulatory approvals or
clearances for its products in foreign countries. See "Business--Government
Regulation" and "--Manufacturing."

FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING

     The Company anticipates that the proceeds of this offering, together with
cash on hand, interest expected to be earned thereon and anticipated revenues
will be sufficient to finance the Company's operations at least through 1997,
although there can be no assurance that additional capital will not be required
sooner. In order to meet its needs beyond this period, the Company may be
required to raise additional funds through public or private financings. Such
financings may not be available when needed on terms acceptable to the Company
or at all. Moreover, any additional equity financings may be dilutive to
purchasers in this offering, and any debt financing may involve restrictive
covenants. An inability to raise such funds when needed might require the
Company to delay, scale back or eliminate some or all of its planned system
enhancements, market expansion and research and development activities, and
might require the Company to cease operations entirely. In such event, all
expenditures to date as well as expenditures from the proceeds of this offering
might not be recoverable. See "Use of Proceeds" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and Capital
Resources."

DEPENDENCE ON PROPRIETARY TECHNOLOGY RIGHTS

     The Company's success will depend in part on its ability to protect its
proprietary rights and to operate without infringing on the proprietary rights
of third parties. In appropriate circumstances, the Company may apply for patent
protection for uses, processes, products and systems that it develops. The
Company currently owns two United States patents and one United States design
patent and has filed eight United States patent applications, one Taiwanese
patent application and one Patent Cooperation Treaty application. There can be
no assurance that any of the Company's current or future patent applications
will result in issued patents, that the scope of any current or future patents
will prevent competitors from introducing competitive products or that any of
the Company's current or future patents would be held valid or enforceable if
challenged. Patenting medical devices involves complex legal and factual
questions and there is no consistent policy regarding the breadth of claims
which issue pertaining to such technologies; the ultimate scope and validity of
patents issued to the Company or to its competitors are thus unknown.

     In addition to patents, the Company intends to rely upon unpatented trade
secrets and know-how and on the expertise of its employees. Although the Company
believes that it has in the past taken, and intends in the future to take,
appropriate steps to protect its unpatented proprietary rights, including
requiring that all of its employees and any third parties granted access to the
Company's proprietary technology enter into confidentiality agreements with the
Company, there can be no assurance that these measures will be sufficient to
protect the Company's rights against third parties. Likewise, there can be no
assurance that others will not independently develop or otherwise acquire
unpatented technologies or products similar or superior to those of the Company.

     There has been substantial litigation regarding patent and other
intellectual property rights in the medical device industry and the Company may
in the future be required to defend its intellectual property rights against
infringement, duplication and discovery by third parties or to defend itself
against third-party claims of infringement. Likewise, disputes may arise in the
future with respect to ownership of technology developed by consultants or under
research or development agreements with pharmaceutical companies, or with
respect to the ownership of technology developed by employees who were
previously employed by other companies. Any such disputes or related litigation
could result in substantial costs to, and a diversion of effort by, the Company.
An adverse determination could subject the Company to significant liabilities to
third parties, require the Company to seek licenses from or pay royalties to
third parties or require the Company to develop appropriate alternative
technology. There can be no assurance that any such licenses would be available
on acceptable terms or at all, or that the Company could develop alternate
technology at an acceptable price or at all. Any of these events could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Products and Technology" and "--Patents."

RISKS ASSOCIATED WITH THIRD-PARTY REIMBURSEMENT OF END USERS

     Sales of the Company's current and proposed systems in certain markets are
dependent in part on the availability of adequate reimbursement from third-party
healthcare payors. Currently, insurance companies and other third-party payors
reimburse the cost of needle-free injectors on a case-by-case basis and may
refuse reimbursement if they do not perceive benefits to their use in a
particular case. Third-party payors are increasingly challenging the pricing of
medical products and services, and there can be no assurance that such third-
party payors will not in the future increasingly reject claims for coverage of
the cost of needle-free injections. In addition, there can be no assurance that
adequate levels of reimbursement will be available to enable the Company to
achieve or maintain market acceptance of its systems or maintain price levels
sufficient to realize profitable operations. Furthermore, there is a possibility
of increased government control or influence over a broad range of healthcare
expenditures in the future. Any such trend could negatively impact the market
for the Company's needle-free injection systems.

DEPENDENCE ON SINGLE SOURCE SUPPLIERS

     The systems currently sold by the Company contain a number of customized
steel components manufactured by third-party suppliers, and the most recently
introduced model Medi-Jector system contains certain plastic components the
molds for which are located at the facilities of the Company's plastics
suppliers.  In addition, certain of the Company's planned systems will contain
plastic disposable front-end chambers which Becton Dickinson has the exclusive
right to manufacture for the Company under the Becton Dickinson Agreement.
Regulatory requirements applicable to medical device manufacturing can make
substitution of suppliers costly and time-consuming.  In the event that the
Company could not obtain adequate quantities of these components from its
suppliers, there can be no assurance that the Company would be able to access
alternative sources of such components within a reasonable period of time, on
acceptable terms or at all.  In particular, if the Company were required to
change suppliers for its current plastic components, it would need either to
move the necessary molds or to obtain new molds, either of which would entail
significant delay.  Similarly, if Becton Dickinson declined to supply the
Company with disposable front-end chambers for its proposed systems, while the
Company has the right to obtain a license to use Becton Dickinson's
technology, it is unlikely that the Company could manufacture such components
as inexpensively as Becton Dickinson.  The unavailability of adequate
quantities, the inability to develop alternative sources, a reduction or
interruption in supply or a significant increase in the price of components
could have a material adverse effect on the Company's ability to manufacture
and market its products.  See "Business--Manufacturing."

PRODUCT LIABILITY AND INSURANCE

     The Company faces an inherent business risk of exposure to product
liability claims in the event that an end user is adversely affected by use or
misuse of its systems, and the Company has in the past experienced such
claims.  The Company currently carries a product liability insurance policy
with an aggregate limit of $5,000,000.  As the result either of adverse claim
experience or of medical device or insurance industry trends, however, the
Company may in the future have difficulty in obtaining product liability
insurance or be forced to pay very high premiums, and there can be no
assurance that insurance coverage will continue to be available on
commercially reasonable terms or at all.  In addition, there can be no
assurance that insurance will adequately cover any product liability claim
against the Company.  A successful product liability or other claim with
respect to uninsured liabilities or in excess of insured liabilities could
have a material adverse effect on the Company's business, financial condition
and operations.  See "Business--Liability Insurance."

NO PRIOR PUBLIC MARKET FOR COMMON STOCK

     Prior to this offering, there has been no public market for the Common
Stock.  There can be no assurance that an active trading market in the Common
Stock will develop or be sustained upon completion of this offering or that
the market price of the Common Stock will not decline below the initial public
offering price.  The initial public offering price of the Common Stock will be
determined by negotiations between the Company and the Representatives of the
Underwriters and may not be indicative of the prices that will prevail in the
public market.  See "Underwriting."

QUARTERLY FLUCTUATIONS IN OPERATING RESULTS

     The Company's operating results may vary significantly from quarter to
quarter, in part because of changes in consumer buying patterns, aggressive
competition, the timing of the recognition of licensing or development fee
payments and the timing of, and costs related to, any future system or new
drug use introductions.  The Company's operating results for any particular
quarter are not necessarily indicative of any future results.  The
uncertainties associated with the introduction of any new system or drug use
and with general market trends may limit management's ability to forecast
short-term results of operations accurately.  Fluctuations caused by
variations in quarterly operating results or the Company's failure to meet
analysts' projections or public expectations as to results may adversely
affect 

                                       11
<PAGE>
 
the market price of the Company's Common Stock. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
POSSIBLE STOCK PRICE VOLATILITY
 
     The trading prices of the Company's Common Stock could be subject to wide
fluctuations in response to events or factors, many of which are beyond the
Company's control.  These could include, without limitation (i) quarter to
quarter variations in the Company's operating results, (ii) announcements by
the Company or its competitors regarding the results of regulatory approval
filings, clinical trials or testing, (iii) developments or disputes concerning
proprietary rights, (iv) technological innovations or new commercial products,
(v) material changes in the Company's collaborative arrangements and (vi)
general conditions in the medical technology industry.  Moreover, the stock
market has experienced extreme price and volume fluctuations, which have
particularly affected the market prices of many medical technology and device
companies and which have often been unrelated to the operating performance of
such companies.

RELIANCE ON KEY PERSONNEL

     The success of the Company is highly dependent, in part, on its ability to
attract and retain highly qualified personnel, including senior management and
scientific personnel.  Competition for such personnel is intense, and there
can be no assurance that the Company will be successful in attracting and
retaining key personnel in the future.  Any failure to do so could adversely
affect the Company.  See "Business--Employees."

CONTROL BY PRINCIPAL SHAREHOLDERS; ANTI-TAKEOVER PROVISIONS

     Upon completion of this offering, certain of the Company's officers,
directors and principal shareholders will beneficially own in the aggregate
approximately 6,078,841 shares of the Company's outstanding Common Stock
(including shares subject to outstanding options and warrants). If these
shareholders vote together as a group, they will be able to substantially
influence the business and affairs of the Company, including the election of
individuals to the Company's Board of Directors (the "Board of Directors"),
and to otherwise affect the outcome of certain actions that require
shareholder approval, including the adoption of amendments to the Company's
articles of incorporation, and certain mergers, sales of assets and other
business acquisitions or dispositions.

     Upon completion of this offering, the Company will have authorized
1,000,000 shares of undesignated preferred stock, $.01 par value, which may be
issued by the Board of Directors on such terms, and with such rights,
preferences and designations, as the Board of Directors may determine without
further shareholder action.  In addition, the Company is subject to certain
provisions of the Minnesota Business Corporation Act that limit the voting
rights of shares acquired in certain acquisitions and restrict certain
business combinations. Some or all of the foregoing factors could have the
effect of discouraging certain attempts to acquire the Company which could
deprive the Company's shareholders of opportunities to sell their shares of
Common Stock at prices higher than prevailing market prices.  See "Principal
Shareholders," "Description of Capital Stock--Preferred Stock" and "--Anti-
Takeover Provisions of the Minnesota Business Corporation Act."

POSSIBLE ADVERSE MARKET EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE

     Sales of significant amounts of Common Stock in the public market or the
perception that such sales will occur could adversely affect the market price
of the Common Stock or the future ability of the Company to raise capital
through an offering of its equity securities. Of the 6,925,633 shares of
Common Stock to be outstanding upon completion of this offering, the 2,200,000
shares offered hereby will be eligible for immediate sale in the public market
without restriction unless they are held by "affiliates" of the Company within
the meaning of Rule 144 of the Securities Act of 1933, as amended (the
"Securities Act"). The remaining 4,725,633 shares of Common Stock will be
"restricted securities" 

                                       12
<PAGE>
 
as that term is defined in Rule 144 under the Securities Act. Of these, an
aggregate of 4,293,378 shares are owned by the Company's directors, officers and
certain of its shareholders who, together with the Company, have agreed that
they will not sell, directly or indirectly, any Common Stock without the prior
consent of Rodman & Renshaw, Inc. for a period of 180 days from the date of this
Prospectus. Of the shares not subject to this agreement, 125,008 shares will
be eligible for immediate sale without restriction pursuant to Rule 144(k) on
the effective date of this offering, 381 shares will be eligible for
sale, subject to compliance with the volume limitations and other restrictions
of Rule 144, 90 days after the effective date of this offering, and 306,866
shares will become eligible for sale under Rule 144 after the expiration of the
two-year holding periods from the dates of acquisition, which end between
December 29, 1996 and May 31, 1998. Beginning on the 181st day after the date of
this Prospectus, when the agreements not to sell shares expire, an additional
929,757 of the shares may become eligible for sale without restriction pursuant
to Rule 144(k), an additional 1,850,526 of the shares will become eligible for
sale, subject to compliance with the volume limitations and other restrictions
of Rule 144, and the remaining 1,513,059 shares will become eligible for sale
under Rule 144 after the expiration of the two-year holding periods from the
dates of acquisition, which end between December 29, 1996 and February 28, 1998.
In addition, certain shareholders and holders of warrants and options, who in
the aggregate beneficially own 5,049,440 shares of Common Stock, have the right,
subject to certain conditions, to include their shares in future registration
statements relating to the Company's securities and to cause the Company to
register for public sale certain Common Stock owned by them. See "Shares
Eligible for Future Sale" and "Underwriting."

IMMEDIATE AND SUBSTANTIAL DILUTION

     Purchasers of the Common Stock offered hereby will experience immediate and
substantial dilution in net tangible book value per share of $5.99. Investors
may also experience additional dilution as a result of the exercise of
outstanding stock options and warrants. See "Dilution."

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 2,200,000 shares of
Common Stock offered hereby are estimated to be approximately $18.0 million
($20.7 million if the Underwriters' over-allotment option is exercised in
full), after deducting the underwriting discounts and estimated offering
expenses and assuming an initial public offering price of $9.00 per share.

     The Company anticipates that the net proceeds of this offering will be used
to fund approximately (i) $6 million of capital expenditures, primarily in
connection with the improvement of the Company's manufacturing and assembly
capability, (ii) $5 million of market development activities, including
increased customer service and support for the marketing efforts of
pharmaceutical and medical device companies with which the Company has
collaborative arrangements and (iii) $5 million of research and development
dedicated to the development of improved needle-free injector systems.

     The balance of the net proceeds will be used for working capital and other
general corporate purposes.  The Company may also use a portion of the net
proceeds to acquire technologies, products or businesses compatible with the
Company's existing business, although the Company has no current arrangements,
commitments or understandings in this regard.  These amounts are estimates,
and the amount and timing of the expenditures for these purposes will depend
upon numerous factors, including the status of the Company's product
development efforts, the nature and timing of future licensing, development or
other collaborative agreements, the timing of regulatory approvals,
competition, manufacturing activities, market acceptance of the Company's
products and other factors.  The Company believes that the net proceeds from
this offering, combined with cash on hand, interest expected to be earned
thereon and anticipated revenues will be sufficient to meet its needs at least
through 1997.

     Pending the use of the net proceeds, the Company plans to invest the funds
in short-term, interest-bearing, investment grade securities.


                              DIVIDEND POLICY

     The Company has not paid any dividends since its inception and for the
foreseeable future intends to follow a policy of retaining all of its
earnings, if any, to finance the development and continued expansion of its
business.  There can be no assurance that the Company will ever pay dividends.
The payment of dividends, if any, in the future will be at the discretion of
the Board of Directors and will depend on the Company's earnings, financial
condition, capital requirements and other relevant factors.

                                   DILUTION
 
     The Company's pro forma net tangible book value as of March 31, 1996 was
$2,882,949, or approximately $0.61 per share.  Pro forma net tangible book
value per share as of March 31, 1996, represents total assets, less intangible
assets and total liabilities, divided by the number of shares outstanding,
after giving effect to a subsequent 1-for-1.313 reverse stock split and the
conversion of all outstanding shares of Convertible Preferred Stock into
Common Stock.  Without taking into account any changes in such net tangible
book value per share after March 31, 1996, other than to give effect to the
sale of the 2,200,000 shares of Common Stock offered hereby at an assumed
initial public offering price of $9.00 per share and the receipt of the net
proceeds of such sale after deducting underwriting discounts and commissions
and estimated expenses payable by the Company, the pro forma net tangible book
value as of March 31, 1996 would have been $20,872,949, or $3.01 per share.
This represents an immediate increase in net tangible book value of $2.40 per
share to existing shareholders and an immediate dilution to new investors of
$5.99 per share, or 66.6%. The following table sets forth this per share
dilution:

</TABLE> 

     If the Underwriters' over-allotment option is exercised in full, the net
tangible book value per share of Common Stock after this offering would be
$3.26 per share, which would result in dilution to new investors of $5.74 per
share, or 63.8%.

     The following table summarizes, as of March 31, 1996, the differences
between existing shareholders and new investors with respect to the total
number of shares of Common Stock purchased from the Company, the total
consideration paid and the average price per share paid (assuming an initial
public offering price of $9.00 share).

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

     The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the Selected
Financial Data and the financial statements and notes thereto included
elsewhere in this Prospectus.  This Prospectus, including the following
discussion, contains forward-looking statements that involve risks and
uncertainties.  The Company's actual results may differ significantly from the
results discussed in the forward-looking statements.  Factors that might cause
such differences include, but are not limited to, those discussed under the
heading "Risk Factors."

GENERAL

     Medi-Ject Corporation designs, manufactures and markets needle-free
injection systems.  In 1993, the Company hired a new management team with the
goal of revitalizing and redefining the Company's strategic direction.  Since
that time, product development efforts have increased, emphasizing reductions
in the cost of the Company's systems to make them more competitive in the
marketplace.  In addition, marketing efforts have been focused on increasing
sales in the domestic insulin market and on expanding the use of needle-free
injection systems for parenteral drugs other than insulin.  As part of this
effort to encourage broader use of needle-free injection systems, the Company
began entering into technology and product license agreements to sell the
Medi-Jector system.  The licensing and development income from these
agreements has been used primarily to fund increased product development
efforts.  This development effort has resulted in a new generation of the
Medi-Jector system, the Medi-Jector VI system, which incorporates molded
plastic components rather than tooled steel components and was introduced in
July 1995, and an innovative needle-free injection technology that is the
subject of eight United States patent applications.

RESULTS OF OPERATIONS

  Three Months Ended March 31, 1996 Compared to Three Months Ended March 31,
  1995

     Revenues increased to approximately $769,000 in the first quarter of 1996
from approximately $542,000 in the first quarter of 1995, an increase of
approximately 42%.  This increase was primarily the result of increased
licensing and product development fees.  Sales of injectors, parts and repairs
declined to approximately $444,000 in the first quarter of 1996 from
approximately $447,000 in the first quarter of 1995, a decrease of
approximately 1%.  This decrease resulted from an unchanged number of injector
sales (811 in each such period) an increased percentage of which were pharmacy
wholesale sales made at a lower average price.  The decrease was partially
offset by an increase in sales of replacement parts and supplies.  Licensing
and product development fees increased to approximately $325,000 in the first
quarter of 1996 from $95,000 in the first quarter of 1995, an increase of
approximately 242%. The increase in fee income reflected both the execution of
the Becton Dickinson Agreement in January 1996 and an increase in fee revenues
from other ongoing development projects.  The Company expects that licensing
and product development fee income will tend to fluctuate on a quarter to
quarter basis, depending on a number of factors, including the timing of the
execution of new development and licensing agreements and the timing, nature
and size of fee payments to be made under existing and new agreements.  In
addition, since the Company in general does not recognize project-based fee
income until the related development work has been performed, quarterly
results will fluctuate with the timing of the Company's research and
development efforts.

     Cost of sales increased to approximately $292,000 in the first quarter of
1996 from approximately $231,000 in the first quarter of 1995, an increase of
approximately 27%.  The increase in cost of sales was due to an increase in
per unit manufacturing costs and an increase in the number of replacement
parts and supplies manufactured.  The Company expects that per injector
manufacturing costs will decrease as volumes increase.

                                       18
<PAGE>
 
     Research and development expenses increased to approximately $450,000 in
the first quarter of 1996 from approximately $269,000 in the first quarter of
1995, an increase of approximately 67%.  This increase was primarily
attributable to research and development expenditures related to the Company's
collaboration with Becton Dickinson, which is being funded in large part by
Becton Dickinson under the Becton Dickinson Agreement.

     General and administrative expenses increased to approximately $389,000 in
the first quarter of 1996 from approximately $331,000 in the first quarter of
1995, an increase of approximately 18%.  The largest component of this
increase was legal expenses related to the negotiation of the Becton Dickinson
Agreement.

     Sales and marketing expenses declined to approximately $213,000 in the
first quarter of 1996 from approximately $241,000 in the first quarter of
1995, a decrease of approximately 12%.  This decrease was primarily the result
of generally reduced spending on domestic sales activities.

     The Company had net interest income of approximately $14,000 in the first
quarter of 1996 compared to net interest expense of approximately $10,000 in
the first quarter of 1995.  The change was the result of increased cash on
hand following the sale of equity securities to Becton Dickinson in January
1996.  In addition, the Company realized income of approximately $8,000 in the
first quarter of 1996 from the sale of certain equipment.

  Year Ended December 31, 1995 Compared to Year Ended December 31, 1994

     Revenues increased to approximately $2,575,000 in 1995 from approximately
$1,988,000 in 1994, an increase of approximately 30%.  This increase was
primarily the result of a growth in licensing and product development fees.
Sales of injectors, parts and repairs increased to approximately $1,654,000 in
1995 from approximately $1,518,000 in 1994, an increase of approximately 9%.
This increase was attributable to an increase in the number of injectors sold,
to 3,110 in 1995 from 2,636 in 1994, largely for use with human growth
hormone.  Licensing and product development fees increased to approximately
$921,000 in 1995 from $470,000 in 1994, an increase of approximately 96%.
This increase was the result of the additional license and development
agreements entered into during 1995 with Bio-Technology General Corporation,
JCR Pharmaceuticals Co., Ltd. and GeneMedicine, Inc., and increased revenue
earned under license and development agreements executed in prior periods.

     Cost of sales increased to approximately $1,049,000 in 1995 from
approximately $631,000 in 1994, an increase of approximately 66%.  This
increase was due in large part to nonrecurring expenses associated with the
commercial introduction of the Medi-Jector VI system.

     Research and development expenses increased to approximately $1,195,000 in
1995 from approximately $401,000 in 1994, an increase of approximately 198%.
This increase was the result of an increased number of research and
development projects at the Company.

     General and administrative expenses increased to approximately $978,000 in
1995 from approximately $868,000 in 1994, an increase of approximately 13%.
This increase related primarily to increased salary and employee benefits
expenses for a larger support staff.

     Sales and marketing expenses increased to approximately $1,146,000 in 1995
from approximately $1,128,000 in 1994, an increase of approximately 2%.

     Interest income remained relatively constant at approximately $16,000 in
both 1995 and 1994.  Interest and other expense increased to approximately
$106,000 in 1995 from approximately $42,000 in 1994, an increase of
approximately 152%.  This increase was largely attributable to a non-cash
expense in 1995 relating to certain modifications to the terms of an investor
option agreement.

                                       19

  Year Ended December 31, 1994 Compared to Year Ended December 31, 1993

     Revenues increased to approximately $1,988,000 in 1994 from approximately
$1,183,000 in 1993, an increase of approximately 68%.  Sales increased to
approximately $1,518,000 in 1994 from approximately $1,058,000 in 1993, an
increase of approximately 43%.  This increase was the result of an increase in
the number of injectors sold to 2,636 in 1994 from 1,399 in 1993, largely
because the Company decreased the prices of its systems in the domestic
insulin market and began to market its systems in Europe and Japan for use
with human growth hormone.  Product development and licensing fees increased
to $470,000 in 1994 from $125,000 in 1993, an increase of approximately 276%.
This increase was the result of the license and development agreement entered
into during 1994 with Schwarz Pharma AG, and revenue under the Ferring NV
license and development agreement entered into in 1993.

     Cost of sales increased to approximately $631,000 in 1994 from
approximately $409,000 in 1993, an increase of approximately 54%.  This
increase was driven primarily by the increase in the number of units produced.

     Research and development expense increased to approximately $401,000 in
1994 from approximately $146,000 in 1993, an increase of approximately 175%.
This increase was the result of increased research and development work
related to the Medi-Jector VI system (which was introduced in 1995) and to
other systems.

     General and administrative expenses increased to approximately $868,000 in
1994 from approximately $615,000 in 1993, an increase of approximately 41%.
This increase was attributable primarily to the hiring of additional
management and support personnel and increased rent expenses.

     Sales and marketing expenses increased to approximately $1,128,000 in 1994
from approximately $485,000 in 1993, an increase of approximately 133%.  This
increase was driven by increased advertising expenditures, the addition of new
sales and marketing personnel and an increase generally in marketing-related
expenditures.

     Interest income increased to approximately $16,000 in 1994 from
approximately $3,000 in 1993, an increase of approximately 433%, as a result
of higher average cash balances resulting from private equity financings
completed during the year.  Interest and other expense increased to
approximately $42,000 in 1994 from approximately $30,000 in 1993, an increase
of approximately 40%, as a result of debt financings completed in 1994.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has financed its operations through private sales of equity and
debt securities, loans, revenues from product sales and licensing and
development fees.  From September 1993 through the first quarter of 1996, the
Company realized net proceeds of approximately $7.6 million from private sales
of its equity securities.  Among other things, these funds were used to
increase sales and marketing and research and development efforts.  In January
1996, the Company received gross proceeds of approximately $3.1 million from a
private sale to Becton Dickinson of shares of convertible preferred stock
(which will convert into 761,615 shares of Common Stock upon the closing of
this offering), options to purchase additional shares of convertible preferred
stock (which will convert into an option to purchase 380,808 shares of Common
Stock at an exercise price of $4.60 per share and which will terminate upon
the closing of this offering unless exercised prior to such time) and warrants
to purchase additional shares of convertible preferred stock (which will
convert into warrants to purchase 1,904,037 shares of Common Stock at $5.91
per share). The Company intends to use these funds, together with monthly
contract development income from Becton Dickinson and from pharmaceutical
company licensees, for the development of the proposed smaller injector and
for the addition of new drug therapies.  See "Business--Products and
Technology" and "Certain Transactions."

     The Company's long term capital requirements will depend on numerous
factors, including the status of the Company's collaborative arrangements, the
progress of the Company's research and development programs and the receipt of
revenues from the sales of the Company's products.  Cash and cash equivalents
were $2.8 million at March 31, 1996.  The Company believes that the net
proceeds to the Company from this offering, combined with cash on hand,
interest expect to be earned thereon and anticipated revenues, will meet its
needs at least through 1997.  In order to meet its needs beyond this period,
the Company may be required to raise additional funds through public or
private financings, including equity financings.

     The Company has not generated taxable income through March 31, 1996, and at
such date it had an accumulated deficit of approximately $9.9 million.

INCOME TAX LOSS CARRYFORWARDS

     At March 31, 1996, the Company had approximately $9.5 million of net
operating loss carryforwards that may be available to offset future taxable
income for federal income tax purposes. These net operating loss carryforwards
begin to expire in 1996. In addition to its net operating loss carryforwards, at
March 31, 1996, the Company had approximately $117,000 in research and
development tax credit carryforwards which begin to expire in 1997.

     Under Section 382 of the Internal Revenue Code of 1986, as amended, and the
regulations thereunder, a change in ownership of greater than 50% of a company
within a three-year period can result in an annual limitation on such
company's ability to utilize net operating loss carryforwards from tax periods
prior to the change in ownership.  The annual limitation may be increased for
any built-in gains recognized within five years of the date of the change in
ownership.  The Company's January 1996 sale of capital stock to Becton
Dickinson resulted in a "change in ownership" of the Company, and future
utilization of the Company's net operating loss carryforwards will be limited
to approximately $1.1 million per year.  If the Company were to undergo a
further "change in ownership," this limitation might be changed.  As a result
of the annual limitation, a portion of the Company's carryforwards may expire
before ultimately becoming available to reduce potential federal income tax
liabilities.  See "Certain Transactions."

                                    BUSINESS

OVERVIEW

     Medi-Ject is a drug delivery company focused on developing, manufacturing
and marketing needle-free injection systems for the self-administration of a
wide range of parenteral (injectable) drugs.  The Company's product, the Medi-
Jector system, is a hand-held, spring-powered device that injects drugs  from
a drug-containing front-end chamber through the skin without a needle as a
narrow, high pressure stream of liquid approximately 7/1000ths of an inch in
diameter.  The Medi-Jector system eliminates the need to pierce the skin with
a hypodermic needle and therefore is perceived by many people to be less
threatening than injection with a needle.  Today's Medi-Jector systems are
smaller, easier to use, less expensive and more comfortable than previous
needle-free injection systems.  The Company believes that the key to
widespread market acceptance of its needle-free injection systems depends upon
continued improvements in these areas.

     The Company believes that needle-free injection systems will benefit
individuals who require self-injection by (i) eliminating the need to pierce
themselves with needles for each injection, which should lead to an increased
willingness to comply with a prescribed injection regimen and consequently
reduce health complications, (ii) providing the ability to inject themselves
discreetly and (iii) eliminating the need for special disposal of used needles.
In addition, healthcare industry providers and payors may benefit from the
decrease in long-term costs of patient care which may result from improved
patient compliance. Furthermore, pharmaceutical companies may benefit from an
increased ability to differentiate their products in the marketplace and
improved patient compliance, both of which may lead to increased sales and
larger market share. Although the single largest indication for self-injection
is the administration of insulin for the treatment of diabetes, the number of
drugs associated with frequent self-injection is increasing as novel
biopharmaceuticals are introduced and individuals previously managed in the
hospital are now cared for in the home.

     Medi-Ject was a pioneer in the development of portable needle-free
injection systems.  Prior to the development of portable systems, needle-free
injection systems were powered by large air compressors and their use was
limited to mass vaccination by the military or school health programs.  These
injectors were painful in comparison to today's injectors.  The Company's
first commercial injector was five times as heavy as its current injector,
which weighs eight ounces.  Acceptance of the Company's needle-free injection
systems has gradually expanded as functionality and ease of use have improved
and the purchase price has been reduced.

INDUSTRY TRENDS

     Historically, with the exception of the self-administration of insulin,
parenteral drug administration was limited to hospitals, doctors' offices and
clinics.  Liquid injectable medicines came packaged in single or multi-dose
vials.  Healthcare professionals filled disposable syringes with the
medication, injected the patient and discarded the used syringe.  Advances in
pharmacology have resulted in an increasing number of drugs that require
frequent injections over long periods of time.  These drugs have provided
dramatic therapeutic effects for conditions that in the past resisted more
conventional medications.

     Although the availability of these drugs provides new treatment
opportunities, the Company believes that the requirement to inject the drugs
has and will continue to hinder their acceptance and reduce patient
compliance.  This perception has led pharmaceutical manufacturers to explore
many alternative delivery technologies, including novel needle injectors (for
example, sheathed and spring-powered needle injectors), transdermal patches,
controlled release oral delivery methods and inhalation devices.  However, the
Company believes that injection will continue as the major delivery method,
because many of these drugs are protein biopharmaceuticals which are destroyed
in the gastrointestinal tract, do not readily penetrate the skin or are not
effectively absorbed through the lungs.

                                       22

     In addition to the increase in the number of drugs requiring self-
injection, changes in the frequency of insulin injections for the treatment of
diabetes also may contribute to an increase in the number of self-injections.
For many years, standard treatment protocol was for insulin to be administered
once or twice daily for the treatment of diabetes. However, according to a
recent study, tightly controlling the disease by, among other things,
administration of insulin as many as four to six times a day, can decrease its
debilitating effects. The Company believes that as the benefits of tightly
controlling diabetes become more widely known, the number of insulin injections
self-administered by individuals with diabetes will increase. The need to
increase the number of injections given per day may lead additional diabetes
patients to seek an alternative to traditional needles and syringes. In Western
Europe, pharmaceutical and medical product companies, including Becton
Dickinson, market pen-like needle injection systems. Patients have demonstrated
a willingness to pay a premium for these systems over traditional needles and
syringes.

     While the Company currently is not pursuing drug applications administered
by healthcare professionals, needle-free injection systems may be attractive to
hospitals, doctors offices and clinics, and the Company may explore such
applications in the future. The issues raised by accidental needle sticks and
disposal of used syringes have led to the development of syringes with sheathed
needles and have led hospitals to give injections through intravenous tubing to
reduce the number of contaminated needles. The Company believes that needle-free
injection systems may be attractive to healthcare professionals as a further
means to reduce accidental needle sticks and the burdens of disposing of
contaminated needles. Becton Dickinson has the option to distribute Medi-Jector
systems to hospitals worldwide.

MARKET OPPORTUNITY

     An estimated nine to 12 billion needles and syringes are sold annually
worldwide.  The Company believes that a significant portion of these are used
for the administration of drugs that could be delivered using the Company's
Medi-Jector system but that only a small percentage of individuals who self-
administer drugs currently use needle-free injection systems.

     The Company's focus is on the market for the delivery of self-administered
parenteral drugs, the largest, most developed portion of which consists of the
delivery of insulin.  In the United States, over 3.2 million people inject
insulin for the treatment of diabetes, resulting in an estimated 2.3 billion
injections annually, and the Company believes that the number of insulin
injections will increase with time as the result of new diabetes management
approaches which recommend more frequent use.  Other parenteral drugs that are
self-administered and may be suitable for injection with the Medi-Jector
system include therapies for the treatment of multiple sclerosis, migraine
headache, growth retardation, impotence, female infertility, AIDS and
hepatitis.  The Company also believes that more existing parenteral drugs will
be self-administered in the future and that additional parenteral drugs that
are under development will be deemed appropriate for self-administration.

STRATEGY

     The Company's goal is to establish its needle-free injectors as the drug
delivery method of choice for the self-administration of a wide range of
parenteral drugs.  The Company believes that the key to this goal is the
development and marketing of a new generation of needle-free injectors that
are less expensive and more user friendly than existing needle-free injection
systems.  The Company's strategic plan for accomplishing this goal consists
of:

     Developing Proprietary Technologies.  To address the need for improved
injector systems, the Company initiated a product development program in 1993.
The Company believes that the design improvements resulting from these efforts
can reduce production costs and lower sales prices.  Central to this program
is a new proprietary injection power source, the gas spring.  The gas spring
injectors will be smaller, operate more intuitively and may give more
comfortable injections.

                                       23
<PAGE>
 
     Generating an Income Stream from Consumable Components.  In addition to
sales of injectors, the Company intends to generate revenue from the ongoing
sale of disposable front-end chambers, which soon will replace the current
stainless steel chambers.

     Collaborating with Pharmaceutical and Medical Device Companies.  To achieve
more rapid distribution of and capture a portion of the value added by the
Company's delivery system, the Company has chosen to pursue licensing and
development agreements with pharmaceutical and medical device companies.  The
Company anticipates that these pharmaceutical and medical device companies
will promote and sell the Medi-Jector systems.  Using this approach will
enable the Company to reduce its marketing expenses and leverage off of the
marketing strength and expertise of the other companies.

     Focusing on Proprietary Pharmaceuticals.  The Company has focused on
entering into agreements covering high-priced drugs, largely
biopharmaceuticals, which may cost many thousands of dollars per year.  The
Company believes that pharmaceutical companies that perceive a problem with
patient compliance have in many instances demonstrated a willingness to fund
the development of alternatives to traditional needle injection.  As new
injectors become available at reduced costs, the Company will address
distribution strategies for less expensive drugs.

PRODUCTS AND TECHNOLOGY

  Current Needle-Free Injection Systems

     The Company's current Medi-Jector system consists of a coil spring
mechanism, a dosage meter, a steel front-end chamber and a plastic adaptor.
This injector is used by arming the spring mechanism, filling the medication
chamber and then setting the pressure level for an optimally effective and
comfortable injection. The coil spring is armed by turning the two overlapping
tubes in the power pack to shorten the coil spring.  The unit is then filled
by placing a plastic adapter on a drug vial, turning the power pack body in
the opposite direction to pull the medication into the front-end chamber until
the proper dosage is displayed in the dosage window and removing the vial and
adapter assembly.  The pressure is adjusted by again turning the winding grip.
An injection is given by holding the Medi-Jector system perpendicular to the
skin in a location appropriate for the injection and pressing the trigger
button.  The most common injection sites are the upper arm, upper thigh,
buttocks or the side of the torso.  It is recommended that the steel front-end
chamber on current models be cleaned after two weeks of use.

     The first lightweight Medi-Jector system, the Medi-Jector EZ system, was
introduced by the Company in 1987.  Although the Medi-Jector EZ system
provided significant advantages over previous needle-free injection systems,
it was fabricated from stainless steel parts, which are expensive to
manufacture.

     In July 1995, the Company introduced the Medi-Jector VI system which
replaced the stainless steel body of the Medi-Jector EZ system with a
composite plastic body.  This change will allow the Company to reduce
manufacturing costs as unit volumes increase.  The composite body also
provides a natural lubricity which reduces friction and therefore the effort
required to arm the coil spring.  The Medi-Jector VI system incorporated
additional design changes to improve functionality.

     New Product Research and Development

     The Company continues to improve its existing products while developing new
products and technology.  Specifically, it is now developing a novel injector
power source which it anticipates will form the basis of a new generation of
pen-like injectors.  In addition, the Company is customizing its injectors in
collaboration with pharmaceutical and medical device companies for use with a
broader range of parenteral drugs.  These development efforts are focused on
making Medi-Jector systems more attractive to users by eliminating the
periodic cleaning requirements, reducing the size of the system, making the
system easier to arm and lowering the cost barrier for new users.

                                       24

     Pen-Like Injectors.  The Company believes that a major obstacle to
widespread market acceptance of needle-free injection systems has been the
lack of a suitably compact and easy to use power source.  Although the Company
has reduced the size and complexity of its coil spring injectors, the Company
believes further reduction in size or improvement in ease of use of systems
using a coil spring are not feasible.  Other companies have developed and
marketed injectors powered by CO/2/ cartridges, but these systems do not
provide any advantage in size and are complex and costly to manufacture.

     To overcome this obstacle, the Company is developing a novel and
proprietary power source, the gas spring.  The Company's gas spring is a
permanently charged gas cylinder that is smaller than a coil spring with
comparable capabilities, allowing the development of smaller systems.  A
rubber seal surrounds a central rod, preventing the gas from escaping and
allowing it to be reused thousands of times.  The spring is armed by pushing
the rod into the cylinder and compressing the gas in the cylinder.  When the
rod is released, it springs forward with the energy stored from arming.  Medi-
Ject built its first prototype gas spring injector in 1994 and filed a patent
application shortly after the successful testing of the technology. Use of the
Company's proprietary gas spring will allow its needle-free injection systems to
be reduced in size and easier to arm and may result in more comfortable
injections.

     Plastic Front-End Chambers.  The Company plans to replace the steel
front-end chamber of the current Medi-Jector system with a multi-use
disposable plastic front-end chamber in its next generation Medi-Jector
system, the Medi-Jector VIB system, which it expects to introduce in late 1996
or early 1997.  The Company believes that one of the reasons its needle-free
injection systems have not gained widespread market acceptance is the
inconvenience of cleaning the systems every two weeks.  The disposable front-
end chamber will eliminate the need to perform this cleaning process and
increase ease of use.  In addition, use of this plastic front-end chamber will
allow the Company to further reduce the manufacturing costs of the Medi-Jector
system.

     The Company expects that each front-end chamber will be labeled for use for
14 injections, subject to FDA approval.  The Company currently anticipates
that the retail selling price of the Medi-Jector VIB  system will be reduced
by 20% to 30% from the price of the current version and the total annual cost
of disposable front-end chambers and related supplies will increase to
approximately $200 per year depending upon the number of injections per day
and the final cost per unit.  Although the total cost to use the Medi-Jector
VIB system over time will be more than with models that do not require
disposable front-end chambers, the Company believes that lowering the initial
purchase price of a Medi-Jector system will encourage more individuals to make
the initial investment in the injector and increase market acceptance.

     In addition, the Company plans to introduce a single-use disposable plastic
front-end chamber for use with its new generation pen-like injectors.  The
Company believes that the single-use disposable chamber will be priced
competitively but at a premium compared to disposable syringes, and that it
will offer users sterility and increased convenience.

     Application Specific Systems.  In addition to pen-like injectors for
insulin, the Company, in collaboration with Becton Dickinson and other
pharmaceutical and medical device companies, is in the process of developing
customized pen-like needle-free injection systems for specific drug
applications.  Modified injectors are being developed for use in gene therapy,
the treatment of erectile dysfunction, and the treatment of multiple
sclerosis.

     Research and Development Programs.  The Company manages four outside
product development programs relating to the further development of (i) the
gas spring, (ii) an electronic dosage display, (iii) an electric arming system
and (iv) the miniaturization of its systems.  In addition, over the past year,
the Company has expanded its internal development efforts by hiring additional
technical personnel, purchasing laboratory equipment and dedicating facility
space to internal product development efforts.  Product development currently
is the largest single category of Company 

                                       25

expenditure, in part supported by fees under license and development agreements.
The Company has expended approximately $146,000, $401,000, $1,195,000 and
$450,000 on research and development efforts during fiscal years 1993, 1994 and
1995 and the first quarter of 1996, respectively. Of these amounts,
approximately $125,000, $470,000, $921,000 and $325,000, respectively, were
funded by third-party sponsored development programs and licensing fees.

TARGET MARKETS

  Insulin

     Approximately 3.2 million people take insulin daily for the control of high
blood sugar observed in individuals with diabetes.  Most of these individuals
take two injections daily, often combining short acting insulin and long
acting insulin.  In the United States, the vast majority of insulin users use
disposable plastic syringes and needles, while in Western Europe and
Japan, in addition to disposable plastic syringes, patients use pen-like
injectors that hold small vial cartridges of insulin and use small needles.
The management of Type I (insulin dependent) diabetes has been found to be
benefitted by a more disciplined approach to glucose management, including,
among other things, more frequent injections, which have been proven to reduce
long-term complications such as heart disease, strokes, neuropathy, kidney
failure and loss of vision.  As a result, some individuals with diabetes take
four to six injections daily.  Needle-free injectors have been available to
and used by diabetes patients with a serious aversion to needles for many
years and for these patients, cost and complexity are not significant barriers
to use.  The Company believes that another, much larger group of individuals,
not seriously averse to needles yet still reluctant to piercing themselves,
find it difficult to comply with injection regimens and would benefit from the
Company's new, less costly and more user friendly needle-free technology.

  Human Growth Hormone

     Approximately 52,000 children worldwide receive frequent injections of
human growth hormone for the treatment of growth retardation. The disease may be
diagnosed as early as age three, with injections administered until bone
maturity is reached at age seventeen or beyond. The hormone drug used for the
treatment of this condition costs an estimated $20,000 or more at the wholesale
level annually. Despite the use of pen-like needle injection systems which are
more convenient to use than traditional needles, compliance with the prescribed
injection regimen continues to be a problem. A study in Germany found that 35%
of children on human growth hormone therapy did not fully comply with the
therapy using needle injections. In addition, a study performed in the
Netherlands showed that most children in the study preferred to have their human
growth hormone administered using a Medi-Jector system rather than a pen-like
needle injector. A small number of pharmaceutical companies currently hold a
significant percentage of the worldwide human growth hormone market. The Company
believes that its needle-free injector system offers a marketing advantage to
the pharmaceutical companies with which it has agreements relating to human
growth hormone.

  Erectile Dysfunction

     Studies estimate the number of men in the United States suffering from
impotence at over fifteen million.  The causes, earlier thought to be mainly
psychogenic, are now thought to be most often a natural result of aging, or a
complication of diabetes, urogenital surgery or other physiological causes.
Over ten years ago, it was observed that penile injections of vasoactive drugs
caused temporary erections sufficient to allow satisfactory sexual
intercourse.  The first drug approved for such use in the United States was
the generic drug prostaglandin E\1\.  However, the Company believes that use
of this drug has been hindered because penile self-injection is difficult and
viewed as unpleasant by most men.  As a result, drug companies are seeking
both local and oral alternative drug delivery methods to avoid the problems of
needle injection.  The Company believes that its needle-free injection
technology may provide an attractive alternative to needles.

                                       26
<PAGE>
 
  Gene Therapy

     Gene therapy involves the injection of replacement genes into the body
instead of biopharmaceutical protein drugs.  In recent years, investigators
have been successful in inserting missing genes directly into the body for
therapeutic purposes.  For example, theoretically, an intramuscular injection
of genes of Factor VIII, the blood component necessary for proper clotting,
which is missing in individuals with hemophilia, could produce sufficient
levels of Factor VIII to prevent excessive bleeding.  Gene therapy is also
being tested as a more effective method of vaccination.  At least one
published study suggests that gene delivery with a needle-free injector
results in higher blood levels of the protein drug or antibodies compared to 
vaccines in animals.

  Multiple Sclerosis

     Multiple sclerosis is a progressive neurological disease where, most
commonly, nerve function loss occurs following an acute episode of peripheral
nerve damage.  The cause of the disease is obscure, but recent studies have
demonstrated that at least three drugs reduce the number of acute episodes.
Each of the drugs is a protein or mixture of proteins and requires frequent
injections, ranging from daily to weekly.  One of these drugs, Betaseron, has
been available in the United States for over one year, and the Company
believes that many individuals using Betaseron are having difficulty with the
prescribed injection regimen due to needle aversion.  As a result, the Company
believes that administration of these drugs would benefit from needle-free
injection systems.  Approximately 100,000 individuals in the United States are
candidates for treatment with such drugs.

  Other Target Markets

     The Company has targeted other parenteral drugs that are regularly self-
administered.  These include narcotic analgesics, the anticoagulant heparin
used to prevent blood clots, hormones used in the treatment of female
infertility, biopharmaceuticals used to treat hepatitis or to elevate red and
white blood cell production following chemotherapy or for the treatment of
AIDS.

     Although the Company has chosen to focus initially on self-injection
opportunities, similar opportunities exist in hospitals, doctors' offices,
clinics, nursing homes and hospices.  Certain opportunities may address the
concern for well being, such as the vaccination of small children, and others
may be prompted by the danger of accidental needle sticks in high risk
environments, such as the emergency room of the hospital.

_______________
(1)  Becton Dickinson has (i) worldwide distribution rights to injectors for use
     with insulin and certain other potential future drugs, (ii) an option for
     distribution rights for injection systems used by healthcare professionals
     and (iii) manufacturing rights to the disposable front-end chambers for any
     indication.

   Becton Dickinson Agreement

     The Company entered into a Development and License Agreement with Becton
Dickinson in January 1996. Under the agreement, Becton Dickinson is required to
pay to the Company periodic development fees for the development of a pen-sized
insulin injector. Becton Dickinson obtained (i) a worldwide license to
distribute the new, smaller pen-like injectors for use with insulin and
potentially certain other drugs and (ii) the exclusive right to manufacture a
disposable front-end chamber for such injector and for injectors to be developed
for use in the administration of such other drugs. Medi-Ject retained the right
to manufacture the injectors. Both companies have certain rights to share in
future revenues generated from injector and disposable front-end chamber sales.
In connection with this transaction, Becton Dickinson purchased convertible
preferred stock and options and warrants to purchase preferred stock from the
Company. See "Certain Transactions--Becton Dickinson."

   Ferring Agreement

     The Company entered into an agreement with Ferring NV ("Ferring") in
December 1993. Pursuant to this agreement, the Company developed and granted
Ferring exclusive rights to use, market and distribute a Medi-Jector system to

hormone manufactured by Bio-Technology General Corporation ("Bio-Technology
General") in Europe. The Company received an initial development fee at the time
the agreement was executed and additional licensing fees are to be paid to the
Company by Ferring at the time of regulatory approval of the product in certain
countries. The Company has retained its rights as the exclusive manufacturer and
supplier of the Medi-Jector system as modified pursuant to this agreement.
Ferring first launched the Medi-Jector system in Germany in October 1994, and
subsequently in certain other European countries. Ferring has purchased
injectors from the Company on a regular basis and has contributed research
funding for the modification of the system to meet certain European regulatory
requirements. Approximately 400 children are using the Medi-Jector system and
have received the Medi-Jector system and training from Ferring without charge.

  JCR Agreement

     In February 1995, the Company entered into a license agreement with JCR
Pharmaceuticals, Ltd. ("JCR") for the use, marketing and distribution of the
Medi-Jector system with human growth hormone in Japan. Recently, JCR has entered
into the human growth hormone market, after licensing the drug from Bio-
Technology General. JCR has distributed approximately 250 injectors for use with
human growth hormone.

  Bio-Technology General Agreement

     The Company entered into an agreement with Bio-Technology General in June
1995. Pursuant to this agreement, the Company developed and granted Bio-
Technology General the exclusive rights to use, market and distribute a Medi-
Jector system to be used in conjunction with its human growth hormone in the
United States in exchange for a licensing fee, research fee payments and ongoing
royalty payments. The Company has retained its rights as the exclusive
manufacturer and supplier of the Medi-Jector system as modified pursuant to this
agreement. The Medi-Jector system was approved for use with the Bio-Technology
General human growth hormone by the FDA in April 1996, but the sale of Bio-
Technology General human growth hormone in the United States is currently
prohibited by a federal injunction issued in late 1995 as a result of an
unresolved patent infringement suit brought by Genentech, Inc. Bio-Technology
General and Medi-Ject are currently considering various options in connection
with the status of this agreement in light of the injunction.

  Schwarz Pharma Agreement

     The Company entered into an agreement with Schwarz Pharma AG ("Schwarz") in
October 1994. Pursuant to this agreement, the Company is to develop and grant
Schwarz the exclusive right to use, market and distribute a Medi-Jector system
for use in conjunction with prostaglandin of the E series for any human ailment,
and any other drug for the treatment of erectile dysfunction. The Company
received an initial fee at the time the agreement was executed and additional
fees are to be paid at the time of reaching certain milestones in the
development. The preliminary design of an injector for this purpose has been
completed and human clinical testing is expected to begin in 1996. Data on
efficacy, pain and tissue damage will be collected prior to finalizing the
design of the injector. Clinical trials of the injector are planned to determine
the occurrence of any adverse effects which commonly occur as a result of
frequent penile needle usage. The Company has retained its rights as the
exclusive manufacturer and supplier of the Medi-Jector system as modified
pursuant to this agreement.

  GeneMedicine Agreement

     The Company entered into an agreement with GeneMedicine, Inc.
("GeneMedicine") in July 1995. GeneMedicine and the Company agreed to
collaborate in the development of an injector to deliver gene constructs to
muscle and solid tissue in humans. The Company received an initial fee at the
time the agreement was executed and additional funds for research support were
paid to the Company at regular intervals thereafter. GeneMedicine may secure
rights to distribute the injector for certain gene therapies in exchange for
licensing fees, and both companies will share in fees and sales revenues

                                       29
<PAGE>
 
generated by licenses to other gene therapy companies. The Company has retained
its rights as the exclusive manufacturer and supplier of the Medi-Jector system
as modified pursuant to this agreement.

  Teva Agreement

     The Company entered into an agreement with Teva Pharmaceutical Industries
Ltd. ("Teva") in May 1996. Teva has obtained a license to distribute a Medi-
Jector system to be modified specifically for the administration of the Teva
drug, Copaxone(R), for the treatment of multiple sclerosis. Copaxone(R) is the
subject of a currently pending FDA new drug application. Teva has agreed to
support the product development work required to modify the injector for
Copaxone(R) administration.

PATENTS

     The Company actively seeks, when appropriate, protection for its products
and proprietary information by means of United States and foreign patents and
trademarks. In addition, the Company relies on trade secrets and confidential
contractual agreements to protect certain proprietary information and products.
The Company currently holds two United States patents relating to the drug vial
adapter and the front-end chamber, one United States design patent relating to
the appearance of the Medi-Jector system and has eight United States patent
applications pending, one Patent Cooperation Treaty application and one
Taiwanese patent application relating to the gas spring energy source and
aspects of its use.

     Much of the Company's technology is being developed on its behalf by
independent outside contractors. To protect the rights of its proprietary know-
how and technology, Company policy requires all employees and consultants with
access to proprietary information to execute confidentiality agreements
prohibiting the disclosure of confidential information to anyone outside of the
Company. These agreements also require disclosure and assignment to the Company
of discoveries and inventions made by such individuals while devoted to Company
sponsored activities. Companies with which the Company has entered into
development agreements have the right to certain technology developed in
connection with such agreements.

     The Company has obtained the rights to certain technology and makes
milestone payments to the inventors of certain core technology. See "Risk
Factors--Dependence on Proprietary Technology Rights."

MANUFACTURING

     The Company operates a manufacturing facility in compliance with current
Good Manufacturing Practices ("GMP") established by the FDA. Injector parts are
manufactured by third-party suppliers and assembled at the Company's facility in
Plymouth, Minnesota. Disposable vial adapters are either assembled at the
Company's facility or by third parties. Quality control and final packaging are
performed on site. A strong effort has been directed toward reducing component
part costs and accelerating assembly procedures, and the Company anticipates a
need to invest in automated assembly equipment as volumes increase in the
future. Becton Dickinson has the right to manufacture the disposable plastic
components of the gas spring systems for the Company in exchange for royalty
payments and certain profit sharing arrangements. See "Risk Factors--Dependence
on Relationship with Becton Dickinson," "Risk Factors--Dependence on Third-party
Suppliers" and "Certain Transactions."

MARKETING

     The Company's strategy is to leverage off of the marketing strength,
existing distribution systems and expertise of the pharmaceutical and medical
device companies with which it collaborates by relying on them to promote and
sell its needle-free injection systems together with the products they
manufacture. The Company anticipates that under these collaborative
arrangements, it will manufacture and supply the needle-free injection
technology for specific drug applications to the 

                                       30
<PAGE>
 
pharmaceutical company which will market the system for use with its drugs. In
some instances pharmaceutical companies may choose to give the injection systems
and disposable components to users without charge as an inducement to customers
to use their products. Becton Dickinson has informed the Company that it intends
to distribute the insulin injection system to be developed under the Becton
Dickinson Agreement through an existing distribution system.
 
     The Company currently sells most Medi-Jector systems through a limited
pharmacy distribution system consisting of approximately 3,100 pharmacies and
pharmacy distributors. Pharmacies marketing the Company's products display sales
literature describing the Medi-Jector system. Often, individuals with diabetes
call the Company directly for additional information regarding the product and
its uses. The Company's sales personnel explain the need for a doctor's
prescription and advise on methods of filing for insurance reimbursement.
Additionally, a small national advertising program in lay journals generates
additional inquiries. Such inquiries are either referred by the Company to local
pharmacies, or may result in mail order sales. The Company also sells a small
number of Medi-Jector systems to exclusive distributors outside the United
States.

     Training is supported by a video and manual that accompany each product
purchased. However, approximately 75% of buyers seek additional help over the
telephone through the Company's customer service department. The Company employs
two nurses to provide training and support for customers through this channel.
The customer service 800 number is prominently displayed on each injector. The
Company plans, coincident with the introduction of the multi-use disposable
front-end chamber, to enlist diabetes nurse educators to promote and train
prospective users. This program will involve placing demonstrator injectors in
selected clinics with the suggestion that individuals, especially those just
beginning insulin therapy, be presented with the choice of needle-free drug
delivery.

     The most common retail price of an injector (which can be used over a
period of several years) is $595, and disposable adapters cost approximately $50
annually. This compares to an annual cost of approximately $140 to use two
syringes with needles daily. The Company anticipates that the retail price of
future generation Medi-Jector systems will be less than the current retail
price, and that additional revenues will be generated by sales of multi-use and
single-use disposable plastic front-end chambers when they are introduced.

COMPETITION

     Competition in the drug delivery market is intensifying. The Company faces
competition from traditional needle syringes, newer pen-like and sheathed needle
syringes and other needle-free injection systems as well as alternative drug
delivery methods including oral, transdermal and pulmonary delivery systems.
Because injection is typically only used when other drug delivery methods are
not feasible, the Company's needle-free injection systems may be made obsolete
by the development or introduction of drugs or drug delivery methods which do
not require injection for the treatment of conditions currently targeted by the
Company. In addition, because the Company intends to enter into collaborative
arrangements with pharmaceutical companies, the Company's competitive position
will depend upon the competitive position of the pharmaceutical company with
which it collaborates for each drug application.

     While competition in the needle-free injection market currently is limited
to small companies with modest financial resources, the barriers to entry are
not great and the Company anticipates additional competition from companies with
greater financial, commercial, personnel and development resources in the
future. Two companies, Health-Mor Personal Care Corp. and Vitajet Corporation,
currently sell coil spring injectors to the United States insulin market. The
products of these companies resemble earlier versions of the Medi-Jector system
and sell at prices ranging from $600 to over $800.

     Another company, Bioject, Inc., has sold a CO/2/ powered injector since
1993. The injector is designed for and used almost exclusively for vaccinations
in doctors' offices or public clinics. Bioject has 

                                       31
<PAGE>
 
announced that it has a contract with a pharmaceutical company to develop a
self-injection system for use with drugs for the treatment of multiple
sclerosis.

     Even though the Company expects the needle-free injection market to expand,
improvements continue to be made in needle syringes, including syringes with
hidden needles and pen-like needle injectors. The Company expects that it will
compete with existing needle injection methods as well as new needle injection
methods yet to be developed.

GOVERNMENT REGULATION

     The Company's products and manufacturing operations are subject to
extensive government regulations, both in the United States and abroad. In the
United States, the FDA administers the FDA Act and has adopted regulations,
including those governing the introduction of new medical devices, the
observation of certain standards and practices with respect to the manufacturing
and labeling of medical devices, the maintenance of certain records and the
reporting of device-related deaths, serious injuries and certain malfunctions to
the FDA. Manufacturing facilities and certain Company records are also subject
to FDA inspections. The FDA has broad discretion in enforcing the FDA Act and
the regulations thereunder, and noncompliance can result in a variety of
regulatory steps ranging from warning letters, product detentions, device alerts
or field corrections to mandatory recalls, seizures, injunctive actions and
civil or criminal actions or penalties.

     Drug delivery systems such as the Company's injectors may be approved or
cleared for sale as a medical device or may be evaluated as part of the drug
approval process in connection with a new drug application ("NDA"). To the
extent permitted under the FDA Act and current FDA policy, the Company intends
to seek the required approvals and clearance for the use of its new injectors,
as modified for use in specific drug applications such as gene therapy, the
treatment of erectile dysfunction, and the treatment of multiple sclerosis,
under the medical device rather than under the new drug provisions of the FDA
Act. As a result of discussions with FDA personnel in connection with the
approval of the Company's injector for use with human growth hormone the Company
believes that, as a general rule, handling these new injectors as devices rather
than as new drugs will be allowed in connection with drugs that have been
previously approved by the FDA; however, the Company anticipates that it will be
required to seek the necessary approvals through an NDA for use of its injectors
with drugs that have not previously been approved by the FDA. There can be no
assurance, however, that any of these new injectors can be handled as medical
devices or that the FDA will not change its current position with respect to
this issue.

     Products regulated as medical devices may not be commercially distributed
in the United States unless they have been cleared or approved by the FDA,
unless otherwise exempted. There are two methods for obtaining such clearance or
approvals. Certain products qualify for a premarket notification under Section
510(k) of the FDA Act ("510(k) notification") of the manufacturer's intention to
commence marketing the product. The manufacturer must, among other things,
establish in the 510(k) notification that the product to be marketed is
substantially equivalent to another legally marketed product (that is, that it
has the same intended use and that it is as safe and effective as a legally
marketed device and does not raise questions of safety and effectiveness that
are different from those associated with the legally marketed device). Marketing
may commence when the FDA issues a letter finding substantial equivalence to
such a legally marketed device. The FDA may require, in connection with a 510(k)
notification, that it be provided with animal and/or human test results. If a
medical device does not qualify for the 510(k) procedure, the manufacturer must
file a premarket approval ("PMA") application under Section 515 of the FDA Act.
A PMA must show that the device is safe and effective and is generally a much
more complex submission than a 510(k) notification, typically requiring more
extensive prefiling testing and a longer FDA review process. The Company
believes that its Medi-Jector systems regulated as medical devices are eligible
for clearance through the 510(k) notification process, although there can be no
assurance that the FDA will not require a PMA in the future.

                                       32
<PAGE>
 
     In addition to submission when a device is being introduced into the market
for the first time, a 510(k) notification is also required when the manufacturer
makes a change or modification to an already marketed device that could
significantly affect safety or effectiveness, or where there is a major change
or modification in the intended use or in the manufacture of the device. When
any change or modification is made in a device or its intended use, the
manufacturer is expected to make the initial determination as to whether the
change or modification is of a kind that would necessitate the filing of a new
510(k) notification. The FDA's regulations provide only limited guidance in
making this determination.

     If the FDA concludes that any or all of the Company's new injectors must be
handled under the new drug provisions of the FDA Act, substantially greater
regulatory requirements and approval times will be imposed. Use of a modified
new product with a previously unapproved new drug will be likely to be handled
as part of the NDA for the new drug itself. Under these circumstances, the
device component will be handled as a drug accessory and will be approved, if
ever, only when the NDA itself is approved. The Company's injector may be
required to be approved as part of the drug delivery system under a supplemental
NDA for use with previously approved drugs. Under these circumstances, the
Company's device could be used with the drug only if and when the supplemental
NDA is approved for this purpose. It is possible that, for some or even all
drugs, the FDA may take the position that a drug-specific approval must be
obtained through a full NDA or supplemental NDA before the device may be labeled
for use with that drug. There can be no assurance that those approvals will be
obtained in a timely manner or at all.

     To the extent that the Company's modified injectors are handled as drug
accessories or part of a drug delivery system, rather than as medical devices,
they are subject to all of the requirements that apply to new drugs. These
include drug GMP requirements, drug adverse reaction reporting requirements, and
all of the restrictions that apply to drug labeling and advertising. In general,
the drug requirements under the FDA Act are more onerous and strict than medical
device requirements. These requirements could have a substantial adverse impact
on the profitability of the Company. Similar requirements apply to systems
regulated as medical devices.

     The Company received 510(k) marketing clearance from the FDA allowing the
Company to market the Medi-Jector IV system in February 1987, the Medi-Jector V
system in October 1988 and for the use of the Medi-Jector system to administer
Bio-Technology General's human growth hormone in April 1996. The Company
determined that a new 510(k) notification was not required in connection with
the commercial introduction of the Medi-Jector VI system which incorporates a
change to a plastic component body, although there can be no assurance that the
FDA will not require a 510(k) notification in the future.

     The Company expects that it will submit a 510(k) notification regarding the
use of plastic front-end chambers with the Medi-Jector VI system in 1996. In
addition, the Company expects in the future to submit 510(k) notifications with
regard to further device design improvements and uses with additional drug
therapies. There can be no assurance that the FDA will grant timely 510(k)
clearance for any such system or use, or that the FDA will not require the
submission of a PMA with respect to any such system or use.

     The FDA Act also regulates the Company's quality control and manufacturing
procedures by requiring the Company and its contract manufacturers to
demonstrate current GMP compliance. These regulations require, among other
things, that (i) the manufacturing process must be regulated and controlled by
the use of written procedures and (ii) the ability to produce devices which meet
the manufacturer's specifications must be validated by extensive and detailed
testing of every aspect of the process. They also require investigation of any
deficiencies in the manufacturing process, the products produced or record-
keeping. Further, the FDA's interpretation and enforcement of these requirements
has been increasingly strict in recent years and seems likely to be even more
stringent in the future. The FDA monitors compliance with these requirements by
requiring manufacturers to register with the FDA and by conducting periodic FDA
inspections of manufacturing facilities. If the inspector observes 

                                       33
<PAGE>
 
conditions that might be violative of the GMP, the manufacturer must correct
those conditions or explain them satisfactorily. Failure to adhere to GMP
requirements would cause the devices produced to be considered in violation of
the FDA Act and subject to FDA enforcement action that might include physical
removal of the Company's devices from the marketplace.

     The FDA's Medical Device Reporting Regulation requires that the Company
provide information to the FDA on the occurrence of any death or serious
injuries alleged to have been associated with the use of the Company's products,
as well as any product malfunction that would likely cause or contribute to a
death or serious injury if the malfunction were to recur. In addition, FDA
regulations prohibit a device from being marketed for unapproved or uncleared
indications. If the FDA believed that the Company was not in compliance with
these regulations, it could institute proceedings to detain or seize the
Company's devices, issue a recall, seek injunctive relief or assess civil and
criminal penalties against the Company or its executive officers, directors or
employees.

     The Company is subject to the Occupational Safety and Health Act ("OSHA")
and other federal, state and local laws and regulations relating to such matters
as safe working conditions, manufacturing practices, environmental protection
and disposal of hazardous or potentially hazardous substances. There can be no
assurance that the Company will not be required to incur significant costs to
comply with such laws, regulations or policies in the future, or that such laws,
regulations or policies will not increase the costs of producing the Company's
devices or otherwise have a material adverse effect upon the Company's ability
to do business.

     Laws and regulations regarding the manufacture, sale and use of medical
devices are subject to change and depend heavily on administrative
interpretations. There can be no assurance that future changes in regulations or
interpretations made by the FDA, OSHA or other regulatory bodies, will not
adversely affect the Company.

     Sales of medical devices outside of the United States are subject to
foreign legal and regulatory requirements. The Company's Medi-Jector EZ systems
have been approved for sale only in certain foreign jurisdictions. Legal
restrictions on the sale of imported medical devices vary from country to
country. The time required to obtain approval by a foreign country may be longer
or shorter than that required for FDA approval, and the requirements may differ.
The Company relies upon the companies marketing its injectors in foreign
countries to obtain the necessary regulatory approvals for sales of its
injectors in those countries. Generally, devices having an effective 510(k)
clearance or PMA may be exported without further FDA authorization. FDA
authorization is generally required in order to export other medical devices.

     The Company is in the process of implementing ISO 9002, a certification
showing that the Company's procedures and manufacturing facilities comply with
standards for quality assurance and manufacturing process control. Such
certification, along with European Medical Device Directive ("MDD")
certification would evidence compliance with the requirements enabling the
Company to affix the CE Mark to its current products. The CE Mark denotes
conformity with European standards for safety and allows certified devices to be
placed on the market in all European Union ("EU") countries. After June 1998,
medical devices may not be sold in EU countries unless they display the CE Mark.
There is no assurance that the Company will obtain the right to affix the CE
Mark prior to such time.

PROPERTY

     The Company leases approximately 9,000 square feet of office, manufacturing
and warehouse space in Plymouth, a suburb of Minneapolis, Minnesota. The lease
expiration date is April 1997. The Company believes its facilities will be
sufficient to meet its requirements through such time and is exploring options
for alternative space.

                                       34

EMPLOYEES

     As of June 1, 1996, the Company employed 30 full-time employees, of whom
six were engaged in administration, eight were engaged in sales and marketing,
four were engaged in research and development, three were engaged in business
development and customer service and nine were engaged in manufacturing. None of
the Company's employees are represented by any labor union or other collective
bargaining unit. The Company believes that its relations with its employees are
good.

LIABILITY INSURANCE

     The business of the Company entails the risk of product liability claims.
Although the Company has not experienced any material product liability claims
to date, any such claims could have a material adverse impact on the Company.
The Company maintains product liability insurance with coverage of $1 million
per occurrence and an annual aggregate maximum of $5 million. The Company
evaluates its insurance requirements on an ongoing basis. There can be no
assurance that product liability claims will be covered by such insurance or
will not exceed such insurance coverage limits or that such insurance will be
available on commercially reasonable terms or at all.

resignation, disqualification, or removal as provided by statute. Dr. Guy was
elected to the Board of Directors as the designee of Ethical under an agreement
between Ethical and the Company. The relevant section of the agreement with
Ethical will terminate upon the closing of this offering. Mr. Jacobs was elected
as the designee of Becton Dickinson under an agreement between Becton Dickinson
and the Company. The relevant terms of the agreement with Becton Dickinson
provide that, so long as Becton Dickinson controls, directly or indirectly, not
less than 5% of the capital stock of the Company, the Company shall use its best
efforts to nominate and elect to the Board of Directors a person designated by
Becton Dickinson and that the Board of Directors shall consist of at least a
majority of members who are not employed by the Company. In the event that a
person designated by Becton Dickinson shall not be a member of the Board of
Directors, Becton Dickinson shall be entitled to notice of and to attend all
meetings of the Board of Directors and its committees and shall receive all
information distributed to the directors at the same time as the directors and
shall receive the same notice of meetings as the directors. These provisions of
the agreement with Becton Dickinson will continue in force following the closing
of this offering. Both Dr. Guy and Mr. Jacobs will continue to serve as
directors upon completion of this offering.

     The Company's executive officers are elected by the Board of Directors and
serve until the next election of officers or until their successors are elected
or appointed and qualify.

Committees

     The Board of Directors has established an Audit Committee and a
Compensation Committee. The Compensation Committee makes recommendations
concerning executive salaries and incentive compensation for employees of the
Company, subject to ratification by the full Board of Directors, and administers
the Company's 1993 Stock Option Plan and the Company's 1996 Stock Option Plan.
The Audit Committee reviews the results and scope of the audit and other
services provided by the Company's independent auditors, as well as the
Company's accounting principles and its system of internal controls, and reports
the results of its review to the full Board of Directors and to management.

DIRECTORS' COMPENSATION

     The Company has not in the past paid cash directors' fees and does not
intend to do so after the closing of this offering. All directors may be
reimbursed for expenses actually incurred in attending meetings of the Board of
Directors and its committees. In the past, the Board of Directors has made
annual discretionary grants of options to purchase shares of Common Stock under
the Company's 1993 Stock Option Plan to all members of the Board of Directors.
The size of these grants has varied from year to year.

EXECUTIVE COMPENSATION

EMPLOYMENT AGREEMENT WITH DR. PASS

     In January 1995, the Company entered into an employment agreement with Dr.
Pass (the "Pass Employment Agreement"). The Pass Employment Agreement provides
for a base salary of $175,000 for 1995 and, as to subsequent years, for a base
salary to be mutually agreed upon between the Company and Dr. Pass prior to the
beginning of each year. For 1996, the parties have agreed that Dr. Pass' base
salary is $192,500. The Pass Employment Agreement also contains provisions
regarding participation in benefits plans, repayment of expenses, participation
in projects and ventures involving the Company and third parties (which is
permitted), protection of confidential information and ownership of intellectual
property. In addition, the Pass Employment Agreement contains covenants that Dr.
Pass will not compete with the Company during the term of his employment and
that he will not solicit or interfere with the Company's customers, suppliers or
employees during the term of his employment and for a period of two years
thereafter. The Pass Employment Agreement had an initial term through December
31, 1995, which term is automatically extended for successive one-year periods
unless either party objects by written notice at least 90 days prior to the end
of the current term. The Pass Employment Agreement may be terminated prior to
the end of the initial term or any extension thereof if Dr. Pass dies; if the
Board of Directors of the Company determines that Dr. Pass has become disabled
(as defined), has breached the Pass Employment Agreement in any material respect
and Dr. Pass has 

                                       39
<PAGE>
 
not cured or cannot cure such breach within 30 days after delivery of written
notice of such breach or has engaged in willful and material misconduct; or if
Dr. Pass is terminated by the Company, with or without cause, following not less
than 90 days' prior written notice.

     The Company maintains a $1,000,000 key person life insurance policy on Dr.
Pass, payable to the Company.

EMPLOYEE STOCK OPTION PLANS

     Under the Company's 1993 Stock Option Plan, as amended (the "1993 Plan"),
and the Company's 1996 Stock Option Plan, as amended (the "1996 Plan" and,
together with the 1993 Plan, the "Plans"), full- and part-time employees of the
Company or of its future subsidiary corporations and directors, consultants and
independent contractors of the Company or of its future subsidiary corporations
are eligible to receive options to purchase Common Stock. The Plans are
administered by the Compensation Committee. The Plans provide for the grant of
both incentive stock options intended to qualify for preferential tax treatment
under Section 422 of the Internal Revenue Code of 1986, as amended, and
nonqualified stock options that do not qualify for such treatment. The exercise
price of all incentive stock options granted under the Plans shall be as
determined by the Compensation Committee, but shall not be less than 100% of the
fair market value of the Common Stock on the date of grant; the exercise price
of nonqualified stock options shall be as determined by the Compensation
Committee. Only employees are eligible for the grant of incentive stock options.

     A total of 495,050 and 500,000 shares of Common Stock have been reserved
for issuance under the 1993 Plan and the 1996 Plan, respectively. As of June 1,
1996, the Company had outstanding options to purchase an aggregate of 481,690
shares with a weighted average exercise price of $2.54 per share under the 1993
Plan and no shares under the 1996 Plan.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Company's Bylaws and the statutes of the State of Minnesota require the
Company to indemnify any director, officer, employee or agent who was or is a
party to any threatened, pending or completed action, suit or proceedings,
whether civil, criminal, administrative or investigative, against certain
liabilities and expenses incurred in connection with the action, suit or
proceeding, except where such persons have not acted in good faith or did not
reasonably believe that the conduct was in the best interests of the Company.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or other persons controlling the Company
pursuant to the foregoing provisions, the Company has been informed that in the
opinion of the SEC, such indemnification is against public policy as expressed
in the Securities Act and is therefore unenforceable.

     On April 16 and June 4, 1993, Fred L. Shapiro, M.D., a director of the
Company, loaned the Company an aggregate of $20,000 pursuant to the terms of
loan agreements and related 9% Demand Promissory Notes; in partial
consideration for these loans, Dr. Shapiro received warrants to purchase an
aggregate of 15,234 shares of Common Stock at $1.31 per share, which warrants
expire on April 16, 1998 and June 3, 1998.  The Company repaid the principal
amount of these loans, together with an aggregate of $747 in interest, on
October 9, 1993.  On August 29, 1994, Dr. Shapiro loaned the Company $100,000

August 31, 1997.  In August 1995, the Company and Dr. Shapiro agreed to extend
the term of the loan and to amend the terms of the loan to permit Dr. Shapiro

February 29, 1996, Dr. Shapiro elected to convert the outstanding principal
amount of this loan into 30,465 shares of Common Stock.  The Company paid Dr.

ETHICAL

     On September 27, 1993, Ethical and the Company entered into a Preferred
Stock Purchase Agreement pursuant to which Ethical purchased 380,808 shares of
Series B Convertible Preferred Stock for a price of $1.31 per share.  At the
same time, the Company and Ethical also entered into (i) an Option Agreement
(the "Ethical Option") pursuant to which Ethical obtained the right to
purchase 761,615 shares of Series B Convertible Preferred Stock at a price of
$1.31 per share (subject to adjustment to $2.62 per share upon the occurrence
of certain events) at any time before the first to occur of March 10, 1995, or
the effectiveness of a registration statement under the Securities Act
registering the Common Stock and (ii) a Technology License and Co-Development
Agreement (the "Ethical License Agreement").  In a letter dated December 10,
1993, Ethical and the Company amended the Ethical Option to provide that the
$1.31 per share price should in all events remain valid as to 380,808 shares
through September 30, 1994.  On March 24, 1995, pursuant to the terms of the
Ethical Option, the exercise price was adjusted to $2.62 upon the Company
raising in excess of $1,000,000 through the sale of additional shares of
capital stock at a price of at least $2.62 per share.  On September 16, 1994,
Ethical and the Company executed a Waiver and Notice of Exercise Agreement
pursuant to which (i) the parties agreed to waive a 380,808 share minimum
exercise amount provision in the Ethical Option, (ii) the parties agreed to a
152,323 share minimum exercise amount for the Ethical Option, (iii) the
parties agreed to extend the $1.31 per share exercise price on 380,808 shares
subject to the Ethical Option through October 31, 1994, and (iv) Ethical
exercised the Ethical Option as to 152,323 shares of Series B Convertible
Preferred Stock for $1.31 per share.  On February 10, 1995, in return for a
commitment by Ethical to exercise $100,000 worth of the Ethical Option under
certain circumstances, the Company and Ethical amended the Ethical Option to
extend its term through September 10, 1995. Ethical exercised the Ethical
Option as to 76,161 shares of Series B Convertible Preferred Stock in February
1995, at a price of $1.31 per share.  Pursuant to an Agreement dated September
1, 1995, between Ethical and the Company, (i) the parties agreed to waive the
380,808 share minimum exercise increment in the Ethical Option, (ii) the
Company agreed to extend the Ethical Option through 

                                       43
<PAGE>
 
February 29, 1996, provided that Ethical exercise the Ethical Option as to at
least 152,323 shares by September 1, 1995, (iii) Ethical exercised the Ethical
Option as to 152,323 shares of Series B Convertible Preferred Stock for $1.64
per share (with the Company agreeing to such price) and (iv) the parties agreed
that the Company would have the unilateral right to terminate the Ethical
License Agreement at any time. In January 1996, the Company and Ethical agreed 
to terminate the Ethical License Agreement.

     On December 22, 1995, Ethical and the Company entered into a Loan
Agreement (the "Ethical Loan") pursuant to which the Company borrowed $312,500
from Ethical in three installments in December 1995 and January 1996; amounts
outstanding under the Ethical Loan bore interest at the rate of 10% per year.
In connection with the Ethical Loan, the Company and Ethical again amended the
Ethical Option to reduce the per share exercise price on 190,404 of the shares
of Series B Convertible Preferred Stock subject to the Ethical Option from
$2.62 to $1.64 and to extend the term of the Ethical Option through the later
of February 29, 1996, or the repayment date of the Ethical Loan.  On February
28, 1996, the Company issued 190,404 shares of Series B Convertible Preferred
Stock to Ethical at a price of $1.64 per share in repayment of all principal
amounts advanced under the Ethical Loan and paid $1,301 interest in cash.  On
the same date, Ethical exercised the remainder of the Ethical Option and
purchased 190,404 shares of Series B Convertible Preferred Stock for $2.62 per
share.

     As the result of certain anti-dilution protections applicable to the
Series B Convertible Preferred Stock sold to Ethical, these shares will
convert upon the effectiveness of this offering into 1,224,198 shares of
Common Stock.

ENSKILDA

     On December 28, 1993, the Company and Enskilda entered into a Preferred
Stock Purchase Agreement pursuant to which Enskilda purchased 57,121 shares of
Series B Convertible Preferred Stock at a purchase price of $1.31 per share.
At the same time, the Company and Enskilda orally agreed that Enskilda should
be allowed to purchase an additional 399,848 shares of Series B Convertible
Preferred Stock.  On February 1, 1994, the Company and Enskilda entered into a
Preferred Stock Agreement pursuant to which Enskilda purchased 399,848 shares
of Non-Voting Series B Convertible Preferred Stock for $1.31 per share.  On
December 29, 1994, Enskilda purchased 30,465 shares of Series B Convertible
Preferred Stock for $3.28 per share as part of a private placement of such
shares.  On May 31, 1995, Enskilda purchased 22,848 shares of Series B
Convertible Preferred Stock for $3.28 per share as part of a private placement
of such shares.

     As the result of certain anti-dilution protections applicable to the
Series B Convertible Preferred Stock sold to Enskilda, these shares will
convert upon the effectiveness of this offering into 542,992 shares of Common
Stock.

BECTON DICKINSON

     On January 25, 1996, the Company and Becton Dickinson entered into a
Preferred Stock, Option and Warrant Purchase Agreement pursuant to which
Becton Dickinson purchased 761,615 shares of Series C Convertible Preferred
Stock for $3.94 per share.  Becton Dickinson also received, for no additional
consideration, an option (the "Becton Dickinson Option") to purchase 380,808
shares of Series D Convertible Preferred Stock at $4.60 per share and
purchased, for $125,000, a warrant (the "Becton Dickinson Warrant") to
purchase 1,904,037 shares of Series E Convertible Preferred Stock at $5.91 per
share.  Under its terms and the proposed terms of this offering, the Becton
Dickinson Option will expire on the date on which the Company completes this
offering.  All shares of Series C convert 1-for-1 into, and the Becton
Dickinson Option and the Becton Dickinson Warrant will become exercisable for,
shares of Common Stock upon the closing of this offering.

     At the same time, the Company and Becton Dickinson entered into a
Development and License Agreement relating to the further development of the
Company's needle-free injection systems and Becton Dickinson's development of
certain disposables for use with the Company's systems.  The terms 

                                       44
<PAGE>
 
of the Development and License Agreement include the grant to Becton Dickinson
during the term of the agreement of an exclusive, world-wide license to (i) sell
and use certain of the Company's needle-free injection systems that are not
designed or calibrated for use with a specific drug made by a specific drug
company and that are intended to be distributed primarily through pharmacies for
non-professional use and (ii) make, have made, use, sell and import single- or
multiple-use disposable front-end chambers or other related drug-containing or
drug-contacting components for use with certain of the Company's needle-free
injection systems.

                         DESCRIPTION OF CAPITAL STOCK


     Upon completion of this offering the authorized capital stock of the
Company will consist of 17,000,000 shares of Common Stock, $.01 par value, and
1,000,000 shares of preferred stock, $.01 par value, that are undesignated as
to terms and preferences. As of June 1, 1996, there were 4,725,633 shares of
Common Stock outstanding, which were held of record by approximately 91
shareholders, and no shares of undesignated preferred stock outstanding.

COMMON STOCK

     The holders of Common Stock are entitled to one vote for each share held
of record on all matters submitted to a vote of shareholders. There is no
cumulative voting for the election of directors so that the holders of more
than 50% of the outstanding Common Stock can elect all directors.  Subject to
preferences that may be applicable to any outstanding preferred stock, holders
of Common Stock are entitled to receive ratably such dividends as may be
declared by the Board of Directors of the Company out of funds legally
available therefor and in liquidation proceedings. Holders of Common Stock
have no preemptive or subscription rights and there are no redemption rights
with respect to such shares.  The outstanding shares of Common Stock are, and
the shares of Common Stock offered hereby will be, validly issued, fully paid
and nonassessable.

PREFERRED STOCK

     All of the Company's outstanding Convertible Preferred Stock will be
converted into Common Stock upon the effectiveness or the closing of this
offering pursuant to its terms.  Immediately after the conversion of the
Convertible Preferred Stock into Common Stock, there will be no Convertible
Preferred Stock outstanding and the Company will have authorized 1,000,000
shares of preferred stock that is undesignated as to terms and preferences.
Under Minnesota law and the Company's Second Amended and Restated Articles of
Incorporation to be effective upon the closing of this offering, the Board of
Directors is authorized, without further shareholder action, to issue
preferred stock in one or more classes or series and to fix the voting rights,
liquidation preferences, dividend rights, repurchase rights, conversion
rights, redemption rights and terms, including sinking fund provisions, and
certain other rights and preferences, of the preferred stock.  Accordingly,
although it has no current intention of doing so, the Board of Directors of
the Company may, without shareholder approval, issue shares of a class or
series of preferred stock with voting and conversion rights which could
adversely affect the voting power and the dividend and other rights of the
holders of Common Stock.  In addition, the existence of undesignated preferred
stock may have the effect of discouraging, delaying, deferring or preventing
an attempt, through acquisition of a substantial number of shares of Common
Stock, to acquire control of the Company with a view to effecting a merger,
sale or exchange of assets or a similar transaction.  The anti-takeover
effects of the undesignated preferred stock may deny shareholders the receipt
of a premium on their Common Stock and may also have a depressive effect on
the market price of the Common Stock.

WARRANTS AND OPTIONS

     As of June 1, 1996, the Company had outstanding options to purchase
481,690 shares of Common Stock that had been issued to employees, directors
and consultants to the Company pursuant to the 1993 

                                       45
<PAGE>
 
Stock Option Plan with a weighted average exercise price of $2.54 per share.
Such options expire between October 1997 and January 2006. As of June 1, 1996,
the Company also had outstanding warrants and options to purchase a total of
2,485,120 shares of Common Stock that have been granted to third parties outside
of the 1993 Stock Option Plan with a weighted average exercise price of $5.35
per share. Such third-party warrants and options are all currently exercisable
and expire on dates ranging from February 1997 to January 2006. All agreements
embodying such outstanding third-party warrants and options provide for
antidilution adjustments in the event of certain mergers, consolidations,
reorganizations, recapitalizations, stock dividends, stock splits or other
changes in the corporate structure of the Company. Holders of third-party
warrants and options to purchase approximately 2,287,893 shares of Common Stock
are entitled to certain rights to cause the Company to register the sale of such
shares under the Securities Act. See "Shares Eligible for Future Sale."

ANTI-TAKEOVER PROVISIONS OF THE 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, to enhance the likelihood of continuity and stability in the
composition of the Board of Directors and in the policies formulated by the
Board of Directors and to discourage an unsolicited takeover of the Company if
the Board of Directors determines that such a takeover is not in the best
interests of the Company and its shareholders. However, these provisions could
have the effect of discouraging certain attempts to acquire the Company, which
could deprive the Company's shareholders of opportunities to sell their shares
of Common Stock at prices higher than prevailing market prices.

     Section 302A.671 of the Minnesota Business Corporation Act (the "MBCA")
provides that, unless the acquisition of certain new percentages of voting
control of the Company (in excess of 20%, 33 1/3% or 50%) by an existing
shareholder or other person is approved by a majority of the disinterested
shareholders of the Company, the shares acquired above such new percentage
level of voting control will not be entitled to voting rights.  The Company is
required to hold a special shareholders' meeting to vote on any such
acquisition within 55 days after the delivery to the Company by the acquirer
of an information statement describing, among other things, the acquirer and
any plans of the acquirer to liquidate or dissolve the Company and copies of
definitive financing agreements for any financing of the acquisition not to be
provided by funds of the acquirer.  If any acquirer does not submit an
information statement to the Company within ten days after acquiring shares
representing a new threshold percentage of voting control of the Company, or
if the disinterested shareholders vote not to approve such an acquisition, the
Company may redeem the shares so acquired by the acquirer at their market
value.  Section 302A.671 generally does not apply to a cash offer to purchase
all shares of voting stock of the issuing corporation if such offer has been
approved by a majority vote of disinterested board members of the issuing
corporation.

     Section 302A.673 of the MBCA restricts certain transactions between the
Company and a shareholder who becomes the beneficial holder of 10% or more of
the Company's outstanding voting stock (an "interested shareholder") unless a
majority of the disinterested directors of the Company have approved, prior to
the date on which the shareholder acquired a 10% interest, either the business
combination transaction suggested by such a shareholder or the acquisition of
shares that made such a shareholder a statutory interested shareholder.  If
such prior approval is not obtained, the statute imposes a four-year
prohibition from the statutory interested shareholder's share acquisition date
on mergers, sales of substantial assets, loans, substantial issuances of stock
and various other transactions involving the Company and the statutory
interested shareholder or its affiliates.

TRANSFER AGENT AND REGISTRAR

     The Transfer Agent and Registrar with respect to the Common Stock will be
Norwest Bank, Minnesota, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Future sales of shares by current shareholders could adversely affect the
price of the Company's Common Stock.

     Upon completion of this offering, the Company will have outstanding an
aggregate of 6,925,633 shares of Common Stock, assuming the issuance of the
2,200,000 shares of Common Stock offered hereby. Of the total outstanding
shares of Common Stock, the 2,200,000 shares offered hereby will be freely
tradeable without restriction or further registration under the Securities
Act, unless held by "affiliates" of the Company, as that term is defined in
Rule 144 under the Securities Act (whose sales would be subject to certain
volume limitations and other restrictions described below).

     The remaining 4,725,633 shares of Common Stock will be "restricted
securities" as that term is defined in Rule 144 under the Securities Act. Of
these, an aggregate of 4,293,378 shares are owned by the Company's directors,
officers and certain of the Company's shareholders who, together with the
Company, have agreed that they will not sell, directly or indirectly, any Common
Stock without the prior consent of Rodman & Renshaw, Inc. for a period of 180
days from the date of this Prospectus. Of the shares not subject to this
agreement, 125,008 shares will be eligible for immediate sale without
restriction pursuant to Rule 144(k) on the effective date of this offering, 381
shares will be eligible for sale, subject to compliance with the volume
limitations and other restrictions of Rule 144, 90 days after the effective date
of this offering, and 306,866 shares will become eligible for sale under Rule
144 after the expiration of the two-year holding periods from the dates of
acquisition, which end between December 29, 1996 and May 31, 1998. Beginning on
the 181st day after the date of this Prospectus, when the agreements not to sell
shares expire, an additional 929,757 of the shares may become eligible for sale
without restriction pursuant to Rule 144(k), an additional 1,850,562 of the
shares will become eligible for sale, subject to compliance with the volume
limitations and other restrictions of Rule 144, and the remaining 1,513,059
shares will become eligible for sale under Rule 144 after the expiration of the
two-year holding periods from the dates of acquisition, which end between
December 29, 1996 and February 28, 1998.

     In general, under Rule 144, as currently in effect, if at least two years
have elapsed from the date that shares of Common Stock were acquired from the
Company or an affiliate of the Company, then the holder is entitled to sell in
"brokers' transactions" or to market makers, within any three-month period
commencing 90 days after the date of this Prospectus, a number of shares that
does not exceed the greater of (i) one percent of the then outstanding shares
of Common Stock (69,256 shares immediately after this offering) or (ii)
generally, the average weekly trading volume in the Common Stock during the
four calendar weeks preceding the filing of a Form 144 with respect to such
sale, subject to certain other limitations and restrictions.  In addition, a
person who is not deemed to have been an affiliate of the Company at any time
during the three months preceding a sale, and who has beneficially owned the
shares proposed to be sold for at least three years, would be entitled to sell
such shares under Rule 144(k) without regard to the requirements described
above.

     The Company intends to file registration statements under the Securities
Act, covering 495,050 and 650,000 shares of Common Stock reserved for issuance
under, respectively, the 1993 Stock Option Plan and the 1996 Stock Option
Plan.  Such registration statements are expected to be filed soon after the
date of this Prospectus and will automatically become effective upon filing.
Accordingly, shares issued under such registration statements upon the
exercise of options will be available for resale in the open market subject to
the agreements not to sell described above.  See "Management--Stock Option
Plans."

     In addition, after this offering, the holders of 2,761,547 shares of
Common Stock and warrants and options to purchase 2,287,893 shares of Common
Stock (together, the "Registrable Securities") will be entitled to certain
rights to cause the Company to register the sale of such shares under the
Securities Act. After this offering, if the Company proposes to register any of
its securities under the Securities Act for its own account, holders of
Registrable Securities will be entitled
                                       47
<PAGE>
 
to notice of such registration and will be entitled to include Registrable
Securities therein, subject to certain conditions and exceptions, including the
right of the underwriters of any such offering to limit the number of shares
that may be included in such registration. Certain of the holders of Registrable
Securities have the right to require the Company to prepare and file a
registration statement under the Securities Act at its expense, and the Company
is required to use its best efforts to effect such registration, subject to
certain conditions and limitations; provided, however, that with respect to
certain of the Registrable Securities, the Company shall not be required to
obtain the effectiveness of any such registration statement until six months
after the date of this Prospectus. Furthermore, the Company's obligation to
effect such shareholder-initiated registrations is limited in number with
respect to certain of the Registrable Securities. Registration of such shares
would result in such shares becoming freely tradeable without restriction under
the Securities Act (except for shares purchased by affiliates of the Company)
immediately upon the effectiveness of such registration. All but 3,048
of these shares are subject to the agreements not to sell described above.

     The Company can make no prediction as to the effect, if any, that sales of
shares of Common Stock or the availability of Common Stock for sale will have on
the market price prevailing from time to time. Nevertheless, sales of
substantial amounts of the Common Stock in the public markets or the perception
that such sales will occur could adversely affect the market price or the future
ability to raise capital through an offering of its equity securities.

J. Steichen & Company are acting as representatives (the "Representatives"),
have severally agreed, subject to the terms and conditions contained in the
Underwriting Agreement, to purchase from the Company, the number of shares of
Common Stock set forth opposite their names below.

</TABLE> 

     The Underwriting Agreement provides that the obligations of the several
Underwriters thereunder are subject to approval of certain legal matters by
counsel and to various other considerations. The nature of obligations is such
that they are committed to purchase and pay for all of the above shares of
Common Stock if any are purchased.

     The Underwriters, through the Representatives, have advised the Company
that they propose to offer the Common Stock initially at the public offering
price set forth on the cover page of this Prospectus; that the Underwriters may
allow to selected dealers a concession of $   per share; and that such dealers
may reallow a concession of $   per share to certain other dealers. After the
public offering, the offering price and other selling terms may be changed by
the Underwriters. Application has been made for the Common Stock to be included
for quotation on the Nasdaq National Market. The Representatives have advised
the Company that they do not intend to confirm sales to any account over which
they exercise discretionary authority.

     The Company has granted to the Underwriters a 30-day over-allotment option
to purchase up to an aggregate of 330,000 additional shares of Common Stock,
exercisable at the public offering price less the underwriting discount. If the
Underwriters exercise such over-allotment option, then each of the Underwriters
will have a firm commitment, subject to certain conditions, to purchase
approximately the same percentage thereof as the number of shares of Common
Stock to be purchased by it as shown in the above table, bears to the 2,200,000
shares of Common Stock offered hereby. The Underwriters may exercise such option
only to cover over-allotments made in connection with the sale of the shares of
Common Stock offered hereby.

     In connection with this offering, the Company has agreed to issue and sell
to the Representatives, for nominal consideration, warrants to purchase a
number of shares of Common Stock equal to 10% of the shares of Common Stock
sold in this offering, exclusive of any shares of Common Stock sold pursuant
to the Underwriters' over-allotment option (the "Representatives' Warrants").
The Representatives' Warrants will be initially exercisable at a price per
share equal to 120% of the public offering price, commencing one year from the
date of this Prospectus, and will continue to be exercisable for a period of
four years after such date.  The Representatives' Warrants are restricted from
sale, transfer, assignment or hypothecation for a period of 12 months from the
effective date of this offering, except to officers, partners or successors of
the Representatives.  The exercise price of the Representatives' Warrants and
the number of shares of Common Stock issuable upon exercise thereof are
subject to adjustment under certain circumstances.  The Representatives'
Warrants grant to the holders thereof certain rights regarding the
registration of the Common Stock issuable upon exercise of the
Representatives' Warrants.

<PAGE>
 
     The officers, directors and certain shareholders of the Company, who will
beneficially own 4,293,378 shares of Common Stock after the offering, have
agreed that they will not publicly sell or dispose of any shares of Common Stock
for a period of 180 days after the date on which the Registration Statement is
declared effective by the Commission, without the prior written consent of
Rodman. See "Shares Eligible for Future Sale."

     The Company has agreed to indemnify the Underwriters against certain
liabilities, losses and expenses, including liabilities under the Securities
Act, or to contribute to payments the Underwriters may be required to make in
respect thereof.

     Prior to this offering, there has been no public market for the Common
Stock.  Consequently, the initial public offering price has been determined
through negotiations between the Company and the Representatives.  Among the
factors considered in determining the initial public offering price were
prevailing market and economic conditions, estimates of the business potential
and prospects of the Company, the present state of the Company's business
operations, an assessment of the Company's management and the consideration of
the above factors in relation to the market valuation of companies in related
businesses.  See "Risk Factors --No Prior Public Market; Possible Volatility
of Price."


                                 LEGAL MATTERS

     The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Dorsey & Whitney LLP, Minneapolis, Minnesota.  Certain
legal matters in connection with the sale of the Common Stock offered hereby
will be passed on for the Underwriters by Squadron, Ellenoff, Plesent &
Sheinfeld, LLP, New York, New York.


                                  EXPERTS

     The financial statements as of December 31, 1994 and 1995, and for each of
the years in the three-year period ended December 31, 1995, included in this
Prospectus have been audited by KPMG Peat Marwick LLP, independent auditors,
as set forth in their report thereon appearing elsewhere herein and in the
Registration Statement, and are included in reliance upon such report given
upon the authority of such firm as experts in accounting and auditing.

     On December 29, 1995, on the recommendation of the Audit Committee and with
the approval of the Board of Directors, the Company engaged KPMG Peat Marwick
LLP to audit the consolidated financial statements of the Company for the year
ended December 31, 1995.  KPMG Peat Marwick LLP has also conducted a reaudit
of the financial statements as of December 31, 1994, and for each of the years
in the two-year period ended December 31, 1994.  There were no disagreements
(whether resolved to the satisfaction of Stirtz Bernards or not) between the
Company and Stirtz Bernards on any matter of accounting principles or
practices, financial statement disclosure, or auditing scope or procedure,
which, if not resolved to the satisfaction of Stirtz Bernards, would have
caused Stirtz Bernards to make a reference to the subject matter of the
disagreement in connection with its report.  The audit opinion of Stirtz
Bernards Boyden Surdel & Larter Professional Association ("Stirtz Bernards"),
the Company's prior accountants, for the years ended December 31, 1993 and
1994 did not contain an adverse opinion or disclaimer of opinion, nor were
they qualified as to uncertainty, audit scope, or accounting principles.

WHEN THE TRANSACTION REFERRED TO IN NOTE 13(A) OF THE NOTES TO FINANCIAL
STATEMENTS HAS BEEN APPROVED BY THE COMPANY'S BOARD OF DIRECTORS, WE WILL BE IN
A POSITION TO RENDER THE FOLLOWING REPORT.


                         Independent Auditors' Report



To the Shareholders and Board of Directors
Medi-Ject Corporation:


We have audited the accompanying balance sheets of Medi-Ject Corporation (the
Company) as of December 31, 1994 and 1995, and the related statements of
operations, shareholders' equity (deficit), and cash flows for each of the years
in the three-year period ended December 31, 1995. 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 Medi-Ject Corporation as of
December 31, 1994 and 1995, and the results of its operations and its cash flows
for each of the years in the three-year period ended December 31, 1995, in
conformity with generally accepted accounting principles.

                         Notes to Financial Statements

                               December 31, 1995
                     (Unaudited as to March 31, 1996 data)


1.   DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Business

          The Company is primarily a manufacturer/distributor of needle-free
     injection devices and disposables for the injection of insulin and human
     growth hormone. Products are sold throughout the United States, Europe, the
     Middle East, and Asia.

     Interim Financial Information

          The financial information presented for the three months ended March
     31, 1996 is unaudited. In the opinion of management, this unaudited
     financial information contains all adjustments (which consist only of
     normal, recurring adjustments) necessary for a fair presentation. Operating
     results for the three months ended March 31, 1996 are not necessarily
     indicative of results that may be expected for the full year.

     Pro Forma Net Loss Per Share

          Pro forma net loss per share is computed by dividing the net loss
     attributable to common shareholders by the weighted average number of
     shares of common stock and common stock equivalents outstanding, after
     applying the treasury stock method and after giving effect to the reverse
     stock split and the automatic conversion of all outstanding shares of
     convertible preferred stock in accordance with the Company's initial public
     offering (see Note 13).

          Pursuant to certain requirements of the Securities and Exchange
     Commission, common stock equivalents include the impact of the issuance of
     stock, options and warrants (see Note 8) within one year prior to the date
     of the initial filing of the Company's initial public offering ("IPO") (see
     Note 13) at exercise prices less than the assumed initial public offering
     price of $9.00 per share, whether or not the effects are antidilutive.


     Cash Equivalents

          The Company considers highly liquid debt instruments with remaining
     maturities of ninety days or less at time of purchase to be cash
     equivalents.

     Inventories

          Inventories are stated at the lower of cost or market. Cost is
     determined on a first-in, first-out basis.

     Equipment, Furniture, and Fixtures

          Equipment, furniture, and fixtures are stated at cost and are
     depreciated using the straight-line method over their estimated useful
     lives.

                         Notes to Financial Statements

                     (Unaudited as to March 31, 1996 data)

     Sales Recognition

          Sales and related costs are recognized upon shipment of product to
     customers. Sales are recorded net of provisions for returns and discounts.

     Licensing and Product Development Revenue Recognition

          Licensing and product development revenue is recognized when
     underlying performance criteria for payment have been met and the Company
     has an unconditional right to such payment. Depending on a license or
     product development agreement's terms, recognition criteria may be
     satisfied upon achievement of milestones, passage of time, or product sales
     by the licensee. Payments received by the Company in excess of amounts
     earned are classified as deferred revenue.

     Product Warranty

          The Company recognizes the estimated cost of warranty obligations to
     its customers at the time the products are shipped.

     Research and Development

          Company sponsored research and development expenses related to both
     present and future products are expensed as incurred.

     Income Taxes

          Deferred tax assets and liabilities are recognized for future tax
     consequences attributable to differences between the financial carrying
     amounts of existing assets and liabilities and their respective tax bases.

     Concentration of Credit Risk

          Financial instruments that may subject the Company to concentration of
     credit risk consist principally of accounts receivable. This risk is
     mitigated by the large number of individual customers and long-standing
     credit relationships with the Company's major distributors.

     Use of Estimates

          The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from these
     estimates.

                         Notes to Financial Statements

                               December 31, 1995
                     (Unaudited as to March 31, 1996 data)


     New Accounting Pronouncements

          For 1996, the Company is required to adopt Statement of Financial
     Accounting Standards No. 121, Accounting for the Impairment of Long-Lived
     Assets and for Long-Lived Assets to be Disposed of, and SFAS No. 123,
     Accounting for Stock-Based Compensation. SFAS No. 121 prescribes accounting
     and reporting standards when circumstances indicate that the carrying
     amount of an asset may not be recoverable. Initial application of SFAS No.
     121 is not expected to result in recognition of a cumulative effect of a
     change in accounting principle by the Company. SFAS No. 123 prescribes
     accounting and reporting standards for all stock-based compensation plans.
     Since the Company intends to elect continued recognition of certain stock-
     based compensation using the intrinsic value method prescribed under
     Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
     Employees, no effect on the Company's expense recognition is expected.

was $57,924, $102,306, and $107,616, respectively.

     The Company is also obligated under noncancelable leases classified as
capital leases. The leases call for aggregate monthly payments of $5,301 with
various expiration dates through September 1999. Equipment, furniture, and

     At December 31, 1995, the Company had net operating loss carryforwards
("NOL") of approximately $9,000,000 for federal income tax purposes, which begin
to expire in 1996. Additionally, the Company had research credit carryforwards
of approximately $117,000, which begin to expire in 1997.

     Pursuant to the Tax Reform Act of 1986, use of the Company's NOL will be
limited because of a cumulative "change of ownership" of more than 50%. This
ownership change occurred as a result of the sale of 1,000,000 shares of Series
C convertible preferred stock on January 25, 1996. (See Note 12.)

8.   SHAREHOLDERS' EQUITY

     Series A Convertible Preferred Stock

     The Series A convertible preferred stock carries voting rights, has no
dividend preference over the Company's common stock and a liquidation
preference of $0.641. Each Series A share is convertible into one share of
common stock at the option of the holder and is, under certain circumstances,
automatically converted to common stock. (See Note 12.)

     Series B Convertible Preferred Stock

     The Series B convertible preferred stock, which carries voting rights, has
dividend preference over Series A convertible preferred and common stock and a
liquidation preference of $1.72.  Each Series B share is convertible into one
share of common stock, subject to certain anti-dilution adjustments.

     In January 1994, the Board of Directors established a new Series B non-
voting convertible preferred stock and authorized 761,615 shares for this
class of stock. The Series B non-voting ranks on par with the Series B voting
convertible preferred stock, with regard to dividends and liquidation
preference, and is convertible at the option of the holder into common stock.

     In October 1994, the Board of Directors established a new Series B, Class
II, voting convertible preferred stock and authorized 304,646 shares for this
class of stock. The Series B-II has a liquidation preference of $3.28 per
share, and otherwise ranks on par with the Series B voting convertible
preferred stock.

     In April 1995, the Board of Directors established a new Series B, Class
III, voting convertible preferred stock and authorized 152,323 shares for this
class of stock. The Series B-III has a liquidation preference of $3.28 per
share, and otherwise ranks on par with the Series B voting convertible
preferred stock.

     In August 1995, the Board of Directors established a new Series B, Class
IV, voting convertible preferred stock and authorized 76,162 shares for this
class of stock. The Series B-IV has a liquidation preference of $3.28 per
share, and otherwise ranks on par with the Series B voting convertible
preferred stock.

     At December 31, 1995, the total number of shares authorized for all classes
of stock was 13,404,420 shares: 7,616,147 common shares; 1,218,584 Series A
preferred shares; 2,284,844 Series B preferred shares; 761,615 nonvoting
Series B preferred shares; and 1,523,230 preferred shares undesignated as to
class.

Stock Options and Warrants

     The Company has issued options and warrants for common stock to various
lenders and others. These options and warrants have exercise prices ranging
from $0.79 to $3.28 per share, are fully exercisable, and expire from August
1996 to December 2003.

     The Company also has stock options outstanding for 380,808 shares of its
Series B convertible preferred stock issued in connection with a 1993 stock
purchase agreement. This option agreement, as amended, expired on February 29,
1996. The exercise price is $1.64 per share for 190,404 shares and $2.63 for
the remaining 190,404 shares. Amendments during 1995 to the Series B preferred
option agreement resulted in the recognition of $45,090 in expense. This
expense was associated with decreases in the exercise price of certain options
in exchange for a short-term credit facility, and the cancellation of a
technology license and co-development agreement. (See Note 12.)

     Under the terms of the Company's 1993 Stock Option Plan, incentive stock
options and nonqualified options may be granted to officers, directors,
employees, and consultants. 495,050 shares of common stock have been reserved
under this plan and at December 31, 1995, 87,891 shares remain available for
grant.

     Stock options granted under the 1993 Stock Option Plan become exercisable
over varying periods and expire up to ten years from date of grant. The option
price for incentive stock options cannot be less than fair market value on the
date of the grant. The option price for nonqualified stock options may be set by
the Board of Directors.

     The Company has an employee savings plan that covers all employees who have
met minimum age and service requirements. Under the plan, eligible employees

12.  SUBSEQUENT EVENTS

     On January 25, 1996, the Company sold 761,615 shares of Series C Junior
convertible preferred stock to Becton Dickinson and Company ("Becton Dickinson")
for $3,000,000. In addition, the Company granted Becton Dickinson an option to
purchase 380,808 shares of Series D Junior preferred stock with an exercise
price of $4.60. These options expire on the tenth anniversary of the agreement
or on the first anniversary of an IPO of the Company's stock if the per share
price is less than $7.88 but more than $6.57, or on the IPO date if the per
share price is greater than or equal to $7.88. Warrants for 1,904,037 shares of
Series E Junior convertible preferred stock were also granted at an exercise
price of $5.91 for initial consideration of $125,000. These warrants expire on
the tenth anniversary of the agreement or on the seventh anniversary following
an IPO if the per share price is greater than or equal to $7.88.

     In connection with the above transaction the Company entered into a
licensing agreement with Becton Dickinson, which provides Becton Dickinson
exclusive worldwide rights to certain Medi-Ject technology. In exchange for
granting this exclusive right, the Company will receive $100,000 per month for
24 months beginning January 1996 to develop the technology.

     On January 25, 1996, the Company converted an unsecured note payable
totaling $312,500 (of which $125,000 is outstanding at year end) into 190,404
shares of Series B convertible preferred stock. In addition, the holder of the
debt purchased an additional 190,404 shares of Series B convertible preferred
stock for proceeds of $500,000 in connection with a stock option exercise. 

     On January 31, 1996, the Company converted its Series A convertible
preferred stock into common stock. Automatic conversion into common stock of the
Series A was precipitated by the Company's net worth exceeding $1.0 million.

     On February 29, 1996 an unsecured note payable to a shareholder totaling 
$100,000, which is outstanding at year end, was converted to 30,465 shares of 
common stock.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 302A.521 of the Minnesota Statutes provides that a corporation shall
indemnify any person made or threatened to be made a party to a proceeding by
reason of the former or present official capacity of such person against
judgments, penalties, fines (including, without limitation, excise taxes
assessed against such person with respect to any employee benefit plan),
settlements and reasonable expenses, including attorneys' fees and
disbursements, incurred by such person in connection with the proceeding, if,
with respect to the acts or omissions of such person complained of in the
proceeding, such person (1) has not been indemnified therefor 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
Section 302A.255 (with respect to director conflicts of interest), if
applicable, has been satisfied; (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 in such person's official capacity for the corporation,
reasonably believed that the conduct was in the best interests of the
corporation, or in the case of acts or omissions in such person's official
capacity for other affiliated organizations, reasonably believed that the
conduct was not opposed to the best interests of the corporation. Section
302A.521 also requires payment by a corporation, 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 shareholders or by a court.

    Provisions regarding indemnification of officers and directors of the
Company to the extent permitted by Section 302A.521 of the Minnesota Statutes
are contained in the Company's Second Amended and Restated Bylaws as they will
be amended immediately upon closing of the offering (Exhibit 3.4 hereto), which
are incorporated herein by reference.

    Under Section 7 of the Underwriting Agreement to be filed as Exhibit 1.1
hereto, the Underwriters have agreed to indemnify, under certain conditions, the
Company, its directors, certain of its officers and persons who control the
Company within the meaning of the Securities Act of 1933, as amended, against
certain liabilities.

ITEM 17.  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 Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the 

                                      II-6
<PAGE>
 
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

     The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

     The undersigned registrant hereby 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.

                     ARTICLE IV - RIGHTS AND PRIVILEGES OF
                          SHARES AND OF SHAREHOLDERS

          The rights, preferences, privileges and restrictions granted to or
imposed upon the respective classes or series of stock or the holders thereof
are set forth below.

          4.1)  Voting Privileges.  Each holder of Common Stock shall have one
vote on all matters submitted to the shareholders for each share of Common Stock
standing in the name of such holder on the books of this Corporation. Each
holder of Series A Preferred Shares shall have one vote on all matters submitted
to the shareholders for each share of Common Stock that such holder of Series A
Preferred Shares would be entitled to receive upon the conversion of such Series
A Preferred Shares as provided in subsection 4.4(d).

          4.2)  Preemptive Rights.  No holder of shares of any class of Capital
Stock shall be entitled as such, as a matter of right, to subscribe for,
purchase or receive any part of any class whatsoever or of securities
convertible into or exchangeable for any stock of any class whatsoever, whether
now or hereafter 

                                      -2-
<PAGE>
 
authorized and whether issued for cash or other consideration or by way of
dividend.

          4.3)  No Cumulative Voting.  No holder of shares of Capital Stock 
shall have any cumulative voting rights.

          4.4)  Series A Preferred Shares.

          (a)  Relative Seniority.  With respect to the relative rights and
preferences set forth herein, the Series A Preferred Shares shall rank senior to
the Common Stock, but may otherwise be junior with respect to the rights and
preferences of any future class or series of Undesignated Preferred Shares that
may be designated by the Board of Directors.  Nothing contained herein shall be
deemed to prevent the Board of Directors from issuing any such Undesignated
Preferred Shares the relative rights and preferences of which may rank senior,
junior, or pari passu with the Series A Preferred Shares.

          (b)  Liquidation Preference.  In the event of the liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the holders of the Series A Preferred Shares shall be entitled to receive in
cash, out of the assets of the Corporation, an amount equal to $.0488 per share
for each outstanding Series A Preferred Share.  If in any such event, the assets
of the Corporation are insufficient to make such payment, the holders of the
Series A Preferred Shares shall be entitled to a ratable distribution.  The
merger or consolidation of the Corporation into or with another Corporation or
the merger or consolidation of any other Corporation into or with the
Corporation (in which consolidation or merger the shareholders of the
Corporation receive distributions of cash or securities or other property as a
result of such consolidation or merger) or the sale, transfer or other
disposition of all or substantially all of the assets of the Corporation shall
be deemed to be a liquidation or dissolution of the Corporation for purposes of
this subparagraph.

          Nothing hereinabove set forth shall affect in any way the right or
obligation of each holder of Series A Preferred Shares to convert such shares at
any time and from time to time in accordance with subsection 4.4(d) below.

          (c)  Dividends and Distributions.  In case this Corporation shall
declare a dividend or other distribution (whether payable in cash, in-kind or
securities of the Corporation, including shares of Common Stock or securities
convertible into Common Stock) upon its Common Stock, the holders of Series A
Preferred Shares shall be deemed to be holders of such number of shares of
Common Stock as the holders of the Series A Preferred Shares are entitled to
receive, upon the conversion thereof as provided in Subsection 4.4(d) below, as
of 

                                      -3-
<PAGE>
 
the record date for such distribution, participating on the same basis as the
holders of the Common Stock in any such dividend or other distribution.

          (d)  Conversion Rights; Mandatory Conversion.

          (1)  Each Series A Preferred Share shall be convertible at the option
     of the holder thereof into one (1) share of Common Stock of this
     Corporation, subject to adjustment as provided for herein. In order to
     exercise the conversion privilege, a holder of Series A Preferred Shares
     shall surrender the certificate representing such shares to the Corporation
     at its principal office, accompanied by written notice to the Corporation
     that the holder elects to convert a specified portion or all of such
     shares. Series A Preferred Shares shall be deemed to have been converted on
     the day of surrender of the certificate representing such shares for
     conversion in accordance with the foregoing provisions, and at such time
     the rights of the holder of such shares, as such holder, shall cease and
     such holder shall be treated for all purposes as the record holder of the
     Common Stock issuable upon conversion. As promptly as practicable on or
     after the conversion date, the Corporation shall issue and mail or deliver
     to such holder a certificate or certificates for the number of shares of
     Common Stock issuable upon conversion, computed to the nearest one-
     hundredth of a full share, and a certificate or certificates for the
     balance of the Series A Preferred Shares surrendered, if any, not so
     converted into Common Stock.

          (2)  The number of shares of Common Stock issuable in exchange for
     Series A Preferred Shares upon the exercise of these conversion rights (the
     "Conversion Ratio") shall be subject to adjustment from time to time as
     hereinafter provided:

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

               (ii)  If any capital reorganization or reclassification of the 
          Capital Stock of the Corporation or consolidation or merger of the
          Corporation with another Corporation or the sale of all or
          substantially all of its assets to another Corporation shall be
          affected in such a way that holders of Common Stock shall be entitled
          to receive stock, securities or assets with respect to or in exchange
          for Common Stock, 

                                      -4-
<PAGE>
 
          then as a condition of such reorganization, reclassification,
          consolidation, merger or sale lawful and adequate provision shall be
          made whereby the holders of Series A Preferred Shares shall thereafter
          have the right to receive, in lieu of the Common Stock of the
          Corporation, immediately theretofore receivable upon the conversion of
          any such Series A Preferred Shares, such shares of stock, securities
          or assets as may be issued or payable with respect to or in exchange
          for a number of outstanding shares of Common Stock equal to the number
          of shares of Common Stock immediately theretofore receivable upon the
          conversion of such Series A Preferred Shares had such reorganization,
          reclassification, consolidation, merger or sale not taken place; and
          in any such case, appropriate provision shall be made with respect to
          the rights and interests of the holders of the Series A Preferred
          Shares to the end that the provisions hereof (including without
          limitation provisions for adjustments of the Conversion Ratio and of
          the number of shares receivable upon the conversion of such Series A
          Preferred Shares) shall thereafter be applicable, as nearly as may be,
          in relation to any shares of stock, securities or assets thereafter
          receivable upon the conversion of such Series A Preferred Shares. This
          Corporation shall not effect any such consolidation, merger or sale,
          unless prior to the consummation thereof the surviving corporation (if
          other than this Corporation), the corporation resulting from such
          consolidation or the corporation purchasing such assets shall assume
          by written instrument executed and mailed to the registered holders of
          the Series A Preferred Shares at the last address of such holders
          appearing on the books of the Corporation, the obligation to deliver
          to such holders such shares of stock, securities or assets, as, in
          accordance with the foregoing provisions, such holders may be entitled
          to receive.
 
          (3)  Upon any adjustment of the Conversion Ratio, then and in each 
     such case, the Corporation shall give written notice thereof by first-class
     mail, postage prepaid, addressed to the registered holders of the Series A
     Preferred Shares at the addresses of such holders as shown on the books of
     the Corporation, which notice shall state the Conversion Ratio resulting
     from such adjustment and the increase or decrease, if any, in the number of
     shares receivable at such price upon the conversion of the Series A
     Preferred Shares, setting forth in reasonable detail the method of
     calculation and the facts upon which such calculation is based.

          (4)  As used in this subsection 4.4(d), the term Common Stock shall
     mean and include this Corporation's presently authorized Common Stock and
     shall also include any capital stock of any class of this Corporation
     hereafter authorized which shall have the right to vote on all matters
     submitted to the shareholders of this Corporation and shall not be limited
     to 

                                      -5-
<PAGE>
 
     a fixed sum or percentage in respect of the rights of the holders thereof
     to participate in dividends or in the distribution of assets upon the
     voluntary or involuntary liquidation, dissolution or winding up of this
     Corporation; provided that the shares receivable pursuant to conversion of
     the Series A Preferred Shares shall include shares designated as Common
     Stock of this Corporation as of the date of issuance of such Series A
     Preferred Shares or, in the case of any reclassification of the outstanding
     shares thereof, the stock, securities or assets provided for in subsection
     4.4(d)(2)(ii) above.

          (5)  Notwithstanding the foregoing right to convert at the option of
     the holder, each Series A Preferred Share shall automatically be deemed
     converted (but only to the extent, and as soon as such conversion would be
     exempt from the registration and qualification requirements of the
     applicable federal and state securities laws) into the appropriate number
     of shares of Common Stock of the Corporation in the manner and upon the
     terms set forth herein, without any act by the Corporation or the holders
     of such shares, on the earlier to occur of (i) the date upon which the
     Corporation completes an offering of its Capital Stock pursuant to a
     registration statement filed pursuant to and declared effective under the
     Securities Act of 1933, as amended, (ii) the calendar month-end upon which
     the Corporation first obtains a total net worth of $1 million, as
     determined pursuant to generally accepted accounting principles, or (iii)
     the date following the merger of the Corporation with or into another
     corporation, the shares of which are currently registered pursuant to
     Section 12 or 15 of the Securities Exchange Act of 1934, as amended, and
     following such merger, (A) the Corporation continues as the surviving
     corporation, (B) the surviving corporation's  common shares are registered
     pursuant to Section 12 or 15 of the Securities Exchange Act of 1934, as
     amended, and (C) the market value of the Corporation equals or exceeds $1
     million, calculated for purposes of this Section 4.4(d), as the product of
     the average closing price for the Corporation's Common Shares during any 20
     consecutive trading days times the number of outstanding Common Shares, and
     including in such number, that number of Common Shares into which the
     Series A Preferred Shares are convertible hereby.

                         ARTICLE V- BOARD OF DIRECTORS

          The Board of Directors of this Corporation shall consist of not more
than nine members.  At all times subsequent to December 31, 1992, a majority of
the members of the Board of Directors shall be persons who are not in the
employment of the Corporation.

                        ARTICLE VI - DIRECTOR LIABILITY

          To the fullest extent permitted by the Minnesota Business Corporation
Act as the same exists or may hereafter be amended, a director of this
Corporation shall not be personally liable to the Corporation or its
shareholders for monetary damages for breach of fiduciary duty as a director.
Any repeal or modification of this Article VI by the shareholders of this
Corporation shall not adversely affect any right existing at the time of such
repeal or modification.

                  $1.00 CONVERTIBLE PREFERRED STOCK, SERIES B

        (Pursuant to Minnesota Statutes, Section 302A.401, Subd. 3(b))
                             _____________________


     The undersigned, being the Secretary of Medi-Ject Corporation (the
"Corporation"), a corporation organized and existing under the Minnesota
Business Corporation Act, in accordance with the provisions of Minnesota
Statutes, Section 302A.401, Subd. 3(b), does hereby certify that:

     Pursuant to the authority vested in the Board of Directors of the
Corporation by the Articles of Incorporation of the Corporation, the Board of
Directors on September 16, 1993 in accordance with Minnesota Statutes, Section
302A.401, Subd. 3, duly adopted the following resolution establishing a series
of 3,000,000 shares of the Corporation's Preferred Stock, to be designated as
its Series B Convertible Preferred Stock:

     RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation (the "Board of Directors") by the Articles of Incorporation
of the Corporation, the Board of Directors hereby establishes a Series B
Convertible Preferred Stock of the Corporation and hereby states the designation
and number of shares, and fixes the relative rights and preferences, of such
series of shares as follows:

     Section 1.  Designation and Amount.  The shares of such series shall be
designated as "Series B Convertible Preferred Stock" (the "Series B Preferred
Shares") and the number of shares constituting such series shall be 3,000,000,
which number may be decreased (but not increased) by the Board of Directors
without a vote of shareholders, provided, however, that such number may not be
decreased below the number of the currently outstanding Series B Preferred
Shares and options for Series B Preferred Shares.

     Section 2.  Dividends and Distributions.

     (a)  The holders of Series B Preferred Shares, in preference to the holders
of shares of the Common Stock, $.01 par value (the "Common Shares") and Series A
Preferred Shares, $.01 par value (the "Series A Preferred Shares"), of the
Corporation, which shall rank junior to the Series B Preferred Shares as to
payment of dividends, shall be entitled to receive, when, as and if declared by
the Board of Directors out of funds legally available for such purpose, cash
dividends on the 
<PAGE>
 
Series B Preferred Shares in such amounts and at such times as declared by the
Board of Directors. However, in no event shall any dividend be paid on any
Common Shares or Series A Preferred Shares unless comparable dividends are paid
on the Series B Preferred Shares. Series B Preferred Shares shall be counted on
an as-if-converted basis in determining whether dividends on Series B Preferred
Shares, Series A Preferred Shares and Common Shares are comparable.

     (b)  Dividends payable pursuant to paragraph (a) shall be in such amount at
least equal to any dividends payable on any other capital stock of the
Corporation as determined on a per share basis.  Holders of Series B Preferred
Shares shall be entitled to receive such dividends in preference to and in
priority over dividends upon the Series A Preferred Shares, Common Shares and
all other capital stock of the Corporation.

     Section 3.  Voting Rights.  The holders of Series B Preferred Shares shall
have the following voting rights:

     (a)  One vote on all matters submitted to the shareholders of the
Corporation for each Common Share that such older of Series B Preferred Shares
would be entitled to receive upon the conversion of such Series B Preferred
Shares.

     (b)  (i)  If an unremedied event of default (an "Event of Default") occurs
under section 11 of the investment agreement, dated September 27, 1993 between
this Corporation and Ethical Holdings plc, a corporation organized under the
laws of England, (the "Investment Agreement"), which Investment Agreement may be
amended from time to time without eh approval of the shareholders of this
Corporation, the holders of Series B Preferred Shares, voting jointly as a
separate class, shall be entitled to designate and elect that number of
directors that is the lowest number that constitutes a majority (the "Majority")
of the members of this Corporation's Board of Directors, and the holders of
Series A Preferred Shares and Common Shares, voting together as a class, shall
be entitled to elect the remaining members of this Corporation's Board of
Directors.  Such right of the holders of Series B Preferred Shares to designate
and elect the Majority of the members of the Board of Directors may be exercised
until the Event of Default under the Investment Agreement has been cured or
waived.  When such Event of Default under the Investment Agreement shall have
been cured or waived, the holders of Series B Preferred Shares shall be divested
of such right to elect the Majority of the members of the Board of Directors,
and any additional directors elected by the holders of Series B Preferred Shares
shall be automatically removed from the Board of Directors without further
action by the Directors or shareholders; subject always to the same provisions
in the vesting of such right in the holders of the Series B Preferred Shares in
the case of any future Event of Default under the Investment Agreement.

          (ii)  The foregoing right of the holders of Series B Preferred Shares
with respect to the election of directors of this Corporation may be exercised
at any annual meeting of shareholders or, within the limitations hereinafter
provided, at a 
<PAGE>
 
special meeting of the shareholders held for such purpose. If the date upon
which such right of the holders of Series B Preferred Shares shall become vested
shall be more than thirty (30) days preceding the date of the next ensuing
annual meeting of shareholders as fixed by the Bylaws of this Corporation, the
President of this Corporation shall, immediately after delivery to this
Corporation at its principal office of a request to such effect signed by the
holders of at least a majority of Series B Preferred Shares then outstanding,
call a special meeting of the shareholders, to be held within fifteen (15) days
after the delivery of such request for the purpose of electing the directors who
they shall designate as the representatives of Series B Preferred Shares on the
Board of Directors, which directors shall serve until the next annual meeting,
until their successors shall be elected and shall qualify or until they are
divested of such office pursuant to the immediately preceding paragraph. Notice
of such meeting shall be mailed to each shareholder not less than ten (10) days
prior to the date of such meeting.

          (iii)  Any holder of Series B Preferred Shares shall have the right, 
during regular business hours, in person or by any authorized representative, to
examine and to make transcripts of the stock records of this Corporation for
Series B Preferred Shares for the purpose of communicating with other holders of
Series B Preferred Shares with respect to the exercise of the foregoing right of
election.

          (iv)  At any annual or special meeting of shareholders held for the
purpose of electing directors when the holders of Series B Preferred Shares
shall be entitled to elect the Majority of the members of the Board of
Directors, the presence in person or by proxy of the holders of a majority of
the outstanding Series B Preferred Shares shall be required to constitute a
quorum for the election by such class of such directors, and the presence in
person or by proxy of the holders of a majority of the outstanding Series A
Preferred Shares and Common Shares shall be required to constitute a quorum for
the election by such class of the remaining directors; provided, however, that
the holders of a majority of either such class of stock who are present in
person or by proxy shall have power to adjourn such meeting for the election of
directors by such class from time to time without notice other than announcement
at the meeting.  No delay or failure by the holders of either of such classes of
stock to elect the members of the Board of Directors whom such holders are
entitled to elect shall invalidate the election of the remaining members of the
Board of Directors by the holders of the other such class of stock.

          (v)  Any director elected by the holders of Series B Preferred Shares
may be removed from office by vote of the holders of at least a majority of the
outstanding Series B Preferred Shares.  A special meeting of the holders of
Series B Preferred Shares may be called by a majority vote of the Board of
Directors for the purpose of removing a director in accordance with the
provisions of this Section 3(b)(v).  The Chairman of the Board of the
Corporation shall, in any event, within 10 days after delivery of the
Corporation at its principal offices of a request to call such a special meeting
signed by the holders of at least 51% of the outstanding Series 
<PAGE>
 
B Preferred Shares, call a special meeting for such purpose to be held as
promptly as practicable after the delivery of such request.

          (vi)  If, during any interval between annual meetings of shareholders
for the election of directors and while the holders of Series B Preferred Shares
shall be entitled to elect the Majority of the members of the Board of
Directors, the number of directors in office who have been elected by the
holders of Series B Preferred Shares or Series A Preferred Shares and Common
Shares, as the case may be, shall, by reason of resignation, death or removal,
be less than the total number of directors subject to election by the holders of
shares of any such class, the vacancy or vacancies in the directors elected by a
given class of shares shall be filled by a majority vote of the remaining
directors then in office who were elected by the holders of such class or
succeeded a director so elected, although such majority may be less than a
quorum.

     (c)  If the Corporation shall not set a date for an annual meeting to elect
directors within thirteen months of the previous annual meeting, then within 10
days after delivery to the Corporation at its principal office of a request to
call such an annual meeting signed by the holders of at least 50% of the
outstanding Series B Preferred Shares, the Chairman of the Board of the
Corporation shall call an annual meeting to be held as promptly as practicable
after the delivery of such request.

     Section 4.  Liquidation, Dissolution or Winding Up.

     (a)  Upon any liquidation, dissolution or winding up of the Corporation, no
distribution shall be made to the holders of shares of capital stock of the
Corporation ranking junior (upon liquidation, dissolution or winding up) to the
Series B Preferred Shares unless, prior thereto, the holders of Series B
Preferred Shares shall, have received the liquidation value per share which, for
each Series B Preferred Share, shall be equal to $1.00 the ("Liquidation
Value").  If, upon any liquidation, dissolution or winding up of the
Corporation, the assets of the Corporation are insufficient to pay such
Liquidation Value per Series B Preferred Share, the holders of such Series B
Preferred Shares shall share pro rata in any such distribution in proportion to
the full amounts to which they would otherwise be respectively entitled.
Following such payment to the holders of Series B Preferred Shares upon such
liquidation, dissolution, or winding up of the Corporation, the holders of
Series A Preferred Shares and Common Shares shall then be entitled, to the
exclusion of the holders of Series B Preferred Shares, to share in all the
assets of this Corporation thereafter remaining in accordance with the relative
rights and preferences of such classes.

     (b)  Neither the consolidation, merger or other business combination of the
Corporation with or into any other individual, firm, corporation or other entity
(including any successor, by merger or otherwise, of such entity) (each a
"Person", collectively, "Persons"), nor the sale of all or substantially all of
the assets of the 
<PAGE>
 
Corporation shall be deemed to be a liquidation, dissolution or winding up of
the Corporation for purposed of this Section 4.

     Section 5.  Conversion.  Each Series B Preferred Share may be converted at
any time, at the option of the holder thereof, into Common Shares, on the terms
and conditions set forth in this Section 5.

     (a)  Each Series B Preferred Share shall be convertible at the option of 
the holder thereof into one (1) Common Shares of this Corporation, subject to
adjustment as provided for herein.  In order to exercise the conversion
privilege with respect to any Series B Preferred Shares, a holder of Series B
Preferred Shares shall surrender the certificate representing such Series B
Preferred Shares to the Corporation at its principal office, accompanied by
written notice to the Corporation that the holder elects to convert a specified
portion or all of such Series B Preferred Shares.  Series B Preferred Shares
shall be deemed to have been converted on the day of surrender of the
certificate representing such Series B Preferred Shares for conversion in
accordance with the foregoing provisions, and at such time the rights of the
holder of such Series B Preferred Shares, as such holder, shall cease and such
holder shall be treated for all purposes as the record holder of the Common
Shares issuable upon conversion.  As promptly as practicable on or after the
conversion date, the Corporation shall issue and mail or deliver to such holder
a certificate or certificates for the number of Common Shares issuable upon
conversion, rounded to the nearest hundredth of a full share, and a certificate
or certificates for the balance of the Series B Preferred Shares surrendered, if
any, not so converted into Common Shares.

     (b)  The number of Common Shares issuable in exchange for Series B 
Preferred Shares upon either optional, or automatic conversion pursuant to
Section 5(g), shall be equal to One Dollar and Twenty-Five Cents ($1.25),
divided by the conversion price then in effect (the "Conversion Price"). The
Conversion Price shall initially be $1.25, but shall be subject to adjustment
from time to time as hereinafter provided:

          (i)  In case this corporation shall at any time subdivide or split its
     outstanding Common Shares into a greater number of shares or declare any
     dividend payable in Common Shares, the Conversion Price in effect
     immediately prior to such subdivision, split or dividend shall be
     proportionately decreased, and conversely, in case the outstanding Common
     Shares of this corporation shall be combined into a smaller number of
     shares, the Conversion Price in effect immediately prior to such
     combination shall be proportionately increased.

          (ii)  Except for issuances for shares or other equity purchase rights
     specifically permitted by the terms of the Investment Agreement, if and
     whenever this Corporation shall issue or sell any Common Shares for a
     consideration per share less than $1.25 (other than dividends payable in
     Series 
<PAGE>
 
     A Preferred Shares or Common Shares), or shall issue any options, warrants
     or other rights for the purchase of such shares at a consideration per
     share of less than $1.25, the Conversion Price in effect immediately prior
     to such issuance or sale shall be adjusted and shall be equal to (i) the
     Conversion Price then in effect, multiplied by (ii) a fraction, the
     numerator of which shall be an amount equal to the sum of (a) the number of
     Series A Preferred Shares and Common Shares outstanding immediately prior
     to such issuance or sale multiplied by the Conversion Price then in effect,
     and (b) the total consideration payable to this Corporation upon such
     issuance or sale of such shares and such purchase rights and upon the
     exercise of such purchase rights, and the denominator of which shall be the
     amount determined by multiplying (aa) the number of Series A Preferred
     Shares and Common Shares outstanding immediately after such issuance or
     sale plus the number of the Common Shares issuable upon the exercise of any
     purchase rights thus issued, by (bb) the Conversion Price then in effect.
     If any options or purchase rights that are taken into account in any such
     adjustment of the Conversion Price subsequently expire without exercise,
     the Conversion Price shall be recomputed by deleting such options or
     purchase rights. If the Conversion Price is adjusted as the result of the
     issuance of any options, warrants or other purchase rights, no further
     adjustment of the Conversion Price shall be made at the time of the
     exercise of such options, warrants or other purchase rights.

          (iii)  The antidilution provisions of this subsection 5(b) may be 
     waived by the affirmative vote of the holders (acting together as a class)
     of at least ninety percent (90%) of the then outstanding Series B Preferred
     Shares.

     (c)  Upon any adjustment of the Conversion Price, then and in each such 
case the Corporation shall give written notice thereof, by first-class mail,
postage prepaid, addressed to the registered holders of Series B Preferred
Shares at the addresses of such holders as shown on the books of this
Corporation, which notice shall state the Conversion Price resulting from such
adjustment and the increase or decrease, if any, in the number of shares
receivable at such price upon the conversion of Series B Preferred Shares,
setting forth in reasonable detail the method of calculation and the facts upon
which such calculation is based.

     (d)  The holders of Series B Preferred Shares shall have the following
rights to certain properties received by the holders of Common Shares:

          (i)  In case this Corporation shall declare a dividend or distribution
     upon Common Shares payable other than in cash out of earnings or surplus or
     other than in Common Shares, then thereafter each holder of Series B
     Preferred Shares upon the conversion thereof will be entitled to receive
     the number of Common Shares into which such Series B Preferred Shares shall
     be converted, and, in addition and without payment therefor, the property
     which such holder would have received as a dividend if continuously since
     the record date for any such dividend or distribution such holder (A) had
<PAGE>
 
     been the record holder of the number of Common Shares then received, and
     (B) had retained all dividends or distributions in stock or securities
     payable in respect of such Common Shares or in respect of any stock or
     securities paid as dividends or distributions and originating directly or
     indirectly from such Common Shares.

          (ii)  If any capital reorganization or reclassification of the capital
     stock of this Corporation, or consolidation or merger of this Corporation
     with another corporation, or the sale of all or substantially all of its
     assets to another corporation shall be effected in such a way that holders
     of Common Shares shall be entitled to receive stock, securities or assets
     with respect to or in exchange for Common Shares, then, as a condition of
     such reorganization, reclassification, consolidation, merger or sale,
     lawful and adequate provision shall be made whereby the holders of Series B
     Preferred Shares shall thereafter have the right to receive, in lieu of
     Common Shares of this Corporation immediately theretofore receivable upon
     the conversion of such Series B Preferred Shares, such shares of stock,
     securities or assets as may be issued or payable with respect to or in
     exchange for a number of outstanding Common Shares equal to the number of
     Common Shares immediately theretofore receivable upon the conversion or
     such Series B Preferred Shares had such reorganization, reclassification,
     consolidation, merger or sale not taken place, and in any such case
     appropriate provision shall be made with respect to me rights and interests
     of the holders of the Series B Preferred Shares to the end that the
     provisions hereof (including without limitation provisions for adjustments
     of the Conversion Price and of the number of shares receivable upon the
     conversion of such Series B Preferred Shares) shall thereafter be
     applicable, as nearly as may be, in relation to any shares of stock,
     securities or assets thereafter receivable upon the conversion of such
     Series B Preferred Shares.  The Corporation shall not effect any such
     reorganization, reclassification, consolidation, merger or sale, unless
     prior to the consummation thereof the surviving corporation (if other than
     this Corporation), the corporation resulting from such consolidation or the
     corporation purchasing such assets shall assume by written instrument
     executed and mailed to the registered holders of the Series B Preferred
     Shares at the last address of such holders appearing on the books of the
     Corporation, the obligation to deliver to such holders such shares of
     stock, securities or assets as, in accordance with the foregoing
     provisions, such holders may be entitled to receive.

     (e)  The Board of Directors may increase the number of Common Shares into
which each Share may be converted, in addition to the adjustments required by
this section, as shall be determined by it (as evidenced by a resolution of the
Board of Directors) to be advisable in order to avoid or diminish any income
deemed to be received by any holder for Federal income tax purposes of Series B
Preferred Shares resulting from any events of occurrences giving rise to
adjustments pursuant to this Section 5 or from any other similar event.
<PAGE>
 
     (f)  As used in this Section 5, the term Common Shares shall mean and
include this Corporation's presently authorized Common Shares and shall also
include any capital stock of any class of this Corporation hereafter authorized
which shall have the right to vote on all matters submitted to the shareholders
of this Corporation and shall not be limited to a fixed sum of percentage in
respect of the rights of the holders thereof to participate in dividends or in
the distribution of assets upon the voluntary or involuntary liquidation,
dissolution or winding up of this Corporation; provided that the shares
receivable pursuant to conversion of the Series B Preferred Shares shall include
shares designated as Common Shares of this Corporation as of the date of
issuance of such Series B Preferred Shares or, in the case of any
reclassification of the outstanding shares thereto, the stock, securities or
assets provided for in Section 5(b)(ii) above.

     (g)  Notwithstanding the foregoing right to convert at the option of the
holder, each Share shall automatically be deemed converted (but only to the
extent, and as soon as such conversion would be exempt from the registration and
qualification requirements of the applicable Federal and state securities laws,
into the appropriate number of Common Shares of the Corporation in the manner
and upon the terms set forth herein, without any act by the Corporation or the
holders of such Series B Preferred Shares, on the earlier to occur of (i) the
date upon which the Corporation completes an offering of its capital stock
pursuant to a registration statement filed pursuant to and declared effective
under the Securities Act of 1933, as amended in which the net proceeds received
by the Corporation equal or exceed $5,000,000 and the per share purchase price
equals or exceeds $4.00 (as adjusted for stock splits, stock dividends or other
corporate reorganizations) or (ii) the date following the merger of the
Corporation with or into another corporation, the shares of which are currently
registered pursuant to Section 12 or 15 of the Securities Exchange Act of 1934,
as amended, and following such merger, (A) the Corporation continues to be the
surviving corporation, (B) the surviving corporation's common shares are
registered pursuant to Section 12 or 15 of the Securities Exchange Act of 1934,
as amended, and (C) the market value of the Corporation equals or exceeds $5
million, calculated for purposes of this Section 5, as the product of the
average closing price for the Corporation's Common Shares during any 20
consecutive trading days times the number of outstanding Common Shares, and
including in such number, that number of Common Shares into which the Series B
Preferred Shares are convertible hereby.

     (h)  The Corporation will pay any and all stamp or similar taxes that may 
be payable in respect of the issuance or delivery of Common Shares on conversion
of Series B Preferred Shares.  The Corporation shall not, however, be required 
to pay any tax which may be payable in respect of any transfer involved in the
issuance and delivery of Common Shares in a name other than that in which the
Series B Preferred Shares so converted were registered, and no such issuance or
delivery shall be made unless and until the Person requesting such issuance has
paid to the 
<PAGE>
 
Corporation the amount of any such tax or has established to the satisfaction of
the Corporation that such tax has been paid.

     IN WITNESS WHEREOF, the undersigned has caused this Certificate of
Designation to be signed on behalf of the Corporation this 17th day of
September, 1993.

     providing for the issue of such series, the voting powers, full or limited,
     if any, of the shares of such series and the designations, preference and
     relative, participating, optional or other special rights and the

     capital stock, and any rights of the holders of the shares of such series

     Corporation is authorized from time to time to accept subscriptions for,

                     ARTICLE IV - RIGHTS AND PRIVILEGES OF
                          SHARES AND OF SHAREHOLDERS

              The rights, preferences, privileges and restrictions granted to or
     imposed upon the respective classes or series of stock or the holders
     thereof are set forth below.

              4.1)  Voting Privileges.  Each holder of Common Stock shall have
     one vote on all matters submitted to the shareholders for each share of
     Common Stock standing in the name of such holder on the books of this
     Corporation. Each holder of Series A Preferred Shares shall have one vote
     on all matters submitted to the shareholders for each share of Common Stock
     that such holder of Series A Preferred Shares would be entitled to receive
     upon the conversion of such Series A Preferred Shares as provided in
     subsection 4.4(d).

              4.2)  Preemptive Rights.  No holder of shares of any class of
     Capital Stock shall be entitled as such, as a matter of right, to subscribe
     for, purchase or receive any part of any class whatsoever or of securities
     convertible into or exchangeable for any stock of any class whatsoever,
     whether now or hereafter authorized and whether issued for cash or other
     consideration or by way of dividend.

              4.3)  No Cumulative Voting.  No holder of shares of Capital Stock
     shall have any cumulative voting rights.

          4.4)  Series A Preferred Shares.

              (a)  Relative Seniority.  With respect to the relative rights and
     preferences set forth herein, the Series A Preferred Shares shall rank
     senior to the Common Stock, but may otherwise be junior with respect to the
     rights and preferences of any future class or series of Undesignated
     Preferred Shares that may be designated by the Board of Directors.  Nothing
     contained herein shall be deemed to prevent the Board of Directors from
     issuing any such Undesignated Preferred Shares the relative rights and
     preferences of which may rank senior, junior, or pari passu with the Series
     A Preferred Shares.

              (b)  Liquidation Preference.  In the event of the liquidation,
     dissolution or winding up of the Corporation, whether voluntary or
     involuntary, the holders of the Series A Preferred Shares shall be entitled
     to receive in cash, out of the assets of the Corporation, an amount equal
     to $.0488 per share for each outstanding Series A Preferred Share.  If in
     any such event, the assets of the Corporation are insufficient to make such
     payment, the holders of the Series A 
<PAGE>
 
     Preferred Shares shall be entitled to a ratable distribution. The merger or
     consolidation of the Corporation into or with another Corporation or the
     merger or consolidation of any other Corporation into or with the
     Corporation (in which consolidation or merger the shareholders of the
     Corporation receive distributions of cash or securities or other property
     as a result of such consolidation or merger) or the sale, transfer or other
     disposition of all or substantially all of the assets of the Corporation
     shall be deemed to be a liquidation or dissolution of the Corporation for
     purposes of this subparagraph.

              Nothing hereinabove set forth shall affect in any way the right or
     obligation of each holder of Series A Preferred Shares to convert such
     shares at any time and from time to time in accordance with subsection
     4.4(d) below.

              (c)  Dividends and Distributions.  In case this Corporation shall
     declare a dividend or other distribution (whether payable in cash, in-kind
     or securities of the Corporation, including shares of Common Stock or
     securities convertible into Common Stock) upon its Common Stock, the
     holders of Series A Preferred Shares shall be deemed to be holders of such
     number of shares of Common Stock as the holders of the Series A Preferred
     Shares are entitled to receive, upon the conversion thereof as provided in
     Subsection 4.4(d) below, as of the record date for such distribution,
     participating on the same basis as the holders of the Common Stock in any
     such dividend or other distribution.

              (d)  Conversion Rights; Mandatory Conversion.

          (1)  Each Series A Preferred Share shall be convertible at the option
     of the holder thereof into one (1) share of Common Stock of this
     Corporation, subject to adjustment as provided for herein. In order to
     exercise the conversion privilege, a holder of Series A Preferred Shares
     shall surrender the certificate representing such shares to the Corporation
     at its principal office, accompanied by written notice to the Corporation
     that the holder elects to convert a specified portion or all of such
     shares. Series A Preferred Shares shall be deemed to have been converted on
     the day of surrender of the certificate representing such shares for
     conversion in accordance with the foregoing provisions, and at such time
     the rights of the holder of such shares, as such holder, shall cease and
     such holder shall be treated for all purposes as the record holder of the
     Common Stock issuable upon conversion. As promptly as practicable on or
     after the conversion date, the Corporation shall issue and mail or deliver
     to such holder a certificate or certificates for the number of shares of
     Common Stock issuable upon conversion, computed to the nearest one-
     hundredth of a full share, and a certificate or certificates for the
     balance of the Series A Preferred Shares surrendered, if any, not so
     converted into Common Stock.

          (2)  The number of shares of Common Stock issuable in exchange for
     Series A Preferred Shares upon the exercise of these conversion rights (the
     "Conversion Ratio") shall be subject to adjustment from time to time as
     hereinafter provided:

               (i)  In case the Corporation shall at any time subdivide or split
          its outstanding Common Stock into a greater number of shares, the
          Conversion Ratio in effect immediately prior to such subdivision or
          split shall be proportionately increased; and, conversely, in case the
          outstanding Common Stock of the Corporation shall be combined into a
          smaller number of shares, the Conversion Ratio in effect immediately
          prior to such combination shall be proportionately reduced.
<PAGE>
 
               (ii)  If any capital reorganization or reclassification of the 
          Capital Stock of the Corporation or consolidation or merger of the
          Corporation with another Corporation or the sale of all or
          substantially all of its assets to another Corporation shall be
          affected in such a way that holders of Common Stock shall be entitled
          to receive stock, securities or assets with respect to or in exchange
          for Common Stock, then as a condition of such reorganization,
          reclassification, consolidation, merger or sale lawful and adequate
          provision shall be made whereby the holders of Series A Preferred
          Shares shall thereafter have the right to receive, in lieu of the
          Common Stock of the Corporation, immediately theretofore receivable
          upon the conversion of any such Series A Preferred Shares, such shares
          of stock, securities or assets as may be issued or payable with
          respect to or in exchange for a number of outstanding shares of Common
          Stock equal to the number of shares of Common Stock immediately
          theretofore receivable upon the conversion of such Series A Preferred
          Shares had such reorganization, reclassification, consolidation,
          merger or sale not taken place; and in any such case, appropriate
          provision shall be made with respect to the rights and interests of
          the holders of the Series A Preferred Shares to the end that the
          provisions hereof (including without limitation provisions for
          adjustments of the Conversion Ratio and of the number of shares
          receivable upon the conversion of such Series A Preferred Shares)
          shall thereafter be applicable, as nearly as may be, in relation to
          any shares of stock, securities or assets thereafter receivable upon
          the conversion of such Series A Preferred Shares. This Corporation
          shall not effect any such consolidation, merger or sale, unless prior
          to the consummation thereof the surviving corporation (if other than
          this Corporation), the corporation resulting from such consolidation
          or the corporation purchasing such assets shall assume by written
          instrument executed and mailed to the registered holders of the Series
          A Preferred Shares at the last address of such holders appearing on
          the books of the Corporation, the obligation to deliver to such
          holders such shares of stock, securities or assets, as, in accordance
          with the foregoing provisions, such holders may be entitled to
          receive.
 
          (3)  Upon any adjustment of the Conversion Ratio, then and in each 
     such case, the Corporation shall give written notice thereof by first-class
     mail, postage prepaid, addressed to the registered holders of the Series A
     Preferred Shares at the addresses of such holders as shown on the books of
     the Corporation, which notice shall state the Conversion Ratio resulting
     from such adjustment and the increase or decrease, if any, in the number of
     shares receivable at such price upon the conversion of the Series A
     Preferred Shares, setting forth in reasonable detail the method of
     calculation and the facts upon which such calculation is based.

          (4)  As used in this subsection 4.4(d), the term Common Stock shall
     mean and include this Corporation's presently authorized Common Stock and
     shall also include any capital stock of any class of this Corporation
     hereafter authorized which shall have the right to vote on all matters
     submitted to the shareholders of this Corporation and shall not be limited
     to a fixed sum or percentage in respect of the rights of the holders
     thereof to participate in dividends or in the distribution of assets upon
     the voluntary or involuntary liquidation, dissolution or winding up of this
     Corporation; provided that the shares receivable pursuant to conversion of
     the Series A Preferred Shares shall include shares designated as Common
     Stock of this Corporation as of the date of issuance of such Series A
     Preferred Shares or, in the case of any reclassification of the outstanding
     shares thereof, the stock, securities or assets provided for in subsection
     4.4(d)(2)(ii) above.
<PAGE>
 
          (5)  Notwithstanding the foregoing right to convert at the option of
     the holder, each Series A Preferred Share shall automatically be deemed
     converted (but only to the extent, and as soon as such conversion would be
     exempt from the registration and qualification requirements of the
     applicable federal and state securities laws) into the appropriate number
     of shares of Common Stock of the Corporation in the manner and upon the
     terms set forth herein, without any act by the Corporation or the holders
     of such shares, on the earlier to occur of (i) the date upon which the
     Corporation completes an offering of its Capital Stock pursuant to a
     registration statement filed pursuant to and declared effective under the
     Securities Act of 1933, as amended, (ii) the calendar month-end upon which
     the Corporation first obtains a total net worth of $1 million, as
     determined pursuant to generally accepted accounting principles, or (iii)
     the date following the merger of the Corporation with or into another
     corporation, the shares of which are currently registered pursuant to
     Section 12 or 15 of the Securities Exchange Act of 1934, as amended, and
     following such merger, (A) the Corporation continues as the surviving
     corporation, (B) the surviving corporation's  common shares are registered
     pursuant to Section 12 or 15 of the Securities Exchange Act of 1934, as
     amended, and (C) the market value of the Corporation equals or exceeds $1
     million, calculated for purposes of this Section 4.4(d), as the product of
     the average closing price for the Corporation's Common Shares during any 20
     consecutive trading days times the number of outstanding Common Shares, and
     including in such number, that number of Common Shares into which the
     Series A Preferred Shares are convertible hereby.

          4.5)  Series B Preferred Shares.

               The rights and preferences of the Series B Preferred Shares shall
     be as set forth in that certain Certificate of Designation, as filed with
     the Secretary of State of the State of Minnesota on September 27, 1993, the
     terms of which are incorporated herein by this reference.

               4.6)  Non-Voting Series B Preferred Shares.  The Non-Voting 
     Series B Preferred Shares shall have identical rights and preferences to
     the Series B Preferred Shares and shall rank pari passu in all respects
     with the Series B Preferred Shares; provided, however, that the holders of
     Non-Voting Series B Preferred Shares shall not have any voting rights,
     except as such may otherwise be prescribed by law."
 

     5.   The amendment has been adopted pursuant to Chapter 302A of the
Minnesota Business Corporation Act.

          IN WITNESS WHEREOF, the undersigned, W. Dirk Dunlap, President of
Medi-Ject  Corporation, being duly authorized on behalf of the Company, has

Convertible Preferred Stock and a series of 2,500,000 shares of the
Corporation's Preferred Stock, to be designated as its Series E Junior
Convertible Preferred Stock:

     RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation (the "Board of Directors") by the Articles of Incorporation
of the Corporation, the Board of Directors hereby establishes a Series C Junior
Convertible Preferred Stock, a Series D Junior Convertible Preferred Stock and a
Series E Junior Convertible Preferred Stock of the Corporation and hereby states
the designation and number of shares, and fixes the relative rights and
preferences, of each such series of shares as follows:

     Section 1.  Designation and Amount.  The Corporation's previously 
undesignated preferred shares shall be designated as to series as follows:

     (a)  1,000,000 shares shall be designated as "Series C Junior Convertible
          Preferred Stock" (the "Series C Preferred Shares"),

     (b)  500,000 shares shall be designated as "Series D Junior Convertible
          Preferred Stock" (the "Series D Preferred Shares") and

     (c)  2,500,000 shares shall be designated as "Series E Junior Convertible
          Preferred Stock" (the "Series E Preferred Shares")
<PAGE>
 
The Series C Preferred Shares, Series D Preferred Shares and Series E Preferred
Shares are referred to collectively herein as the "Series C, D and E Preferred
Shares".

     Section 2.  Dividends and Distributions.

     (a)  The holders of Series C, D and E Preferred Shares, in preference to 
and in priority over the holders of shares of the Common Stock, $.01 par value
(the "Common Shares") and Series A Preferred Shares, $.01 par value (the "Series
A Preferred Shares"), of the Corporation, each of which shall rank junior to the
Series C, D and E Preferred Shares as to payment of dividends, shall be entitled
to receive, when, as and if declared by the Board of Directors out of funds
legally available for such purpose, cash dividends on the Series C, D and E
Preferred Shares in such amounts and at such times as declared by the Board of
Directors; provided, however, that the holders of the Series C, D and E
Preferred Shares shall not be entitled to receive any dividends on the Series C,
D and E Preferred Shares, and no such dividends shall be declared or paid,
unless and until comparable dividends are declared and paid to the holders of
the Corporation's Series B Convertible Preferred Shares, $.01 par value per
share (the "Series B Preferred Shares"). Dividends payable pursuant hereto shall
be in such amount at least equal to any dividends payable on the Series A
Preferred Shares or the Common Shares determined on an as-if-converted basis.

     (b)  In no event shall any dividend be paid on any Common Shares or Series 
A Preferred Shares unless dividends are paid on the Series C, D and E Preferred
Shares in accordance with subparagraph (a) .  Holders of Series C, D and E
Preferred Shares shall be entitled to receive dividends comparable to dividends
on the Series B Preferred Shares.

     (c)  Series A Preferred Shares, Series B Preferred Shares and Series C, D
and E Preferred Shares shall be counted on an as-if-converted basis in
determining whether dividends on any such preferred shares or Common Shares are
comparable.

     (d)  Notwithstanding anything to the contrary contained herein, the
provisions of this Section 2 shall not apply to dividends payable in Common
Shares or Common Stock Equivalents (as defined in Section 5.1) for which an
appropriate adjustment is made in the Conversion Price (as defined in Section
5.1) pursuant to Section 5.3(d).

     Section 3.  Voting Rights.

     (a)  General.  Except as otherwise provided herein, the holders of Series 
C, D and E Preferred Shares shall have one vote on all matters submitted to the
shareholders of the Corporation for each Common Share that such holder of Series
C, D or E Preferred Shares would be entitled to receive upon the conversion of
such Series C, D or E Preferred Shares.

                                      -2-
<PAGE>
 
     (b)  Election of Director.  Subject to the provisions of Section 3(b) of 
the Certificate of Designations for the Series B Preferred Shares, at any time
there are outstanding any Series C, D or E Preferred Shares, the holders of the
Series C, D and E Preferred Shares, exclusively and voting as a single class,
shall be entitled, by a vote of holders of a majority of the total voting power
to which such holders are entitled as set forth in subparagraph (a) above, to
elect one of the directors of the Corporation and to exercise any right of
removal or replacement of such director.

     Section 4.  Liquidation, Dissolution or Winding Up.

     (a)  Subject to the provisions of subparagraph (b) hereof, upon any
liquidation, dissolution or winding up of the Corporation, no distribution shall
be made to the holders of shares of capital stock of the Corporation ranking
junior (upon liquidation, dissolution or winding up) to the Series C, D and E
Preferred Shares unless, prior thereto, the holders of outstanding Series C, D
and E Preferred Shares shall have received the liquidation value per share
which, for each Series C Preferred Share, shall be equal to $3.00, for each
Series D Preferred Share, shall be equal to $3.50 and for each Series E
Preferred Share, shall equal $4.50 (each such liquidation value per share shall
be subject to appropriate adjustment to reflect stock splits, stock dividends,
reorganizations, consolidations and similar changes hereafter effected) (the
"Liquidation Value").  If, upon any liquidation, dissolution or winding up of
the Corporation, the assets of the Corporation are insufficient to pay such
Liquidation Value per Series C, D or E Preferred Share, after payment to the
holders of the Series B Preferred Shares as set forth in subparagraph (b) below,
the holders of such Series C, D and E Preferred Shares shall share pro rata in
the remaining assets.  Following such payment to the holders of Series B, C, D
and E Preferred Shares upon such liquidation, dissolution, or winding up of the
Corporation, the holders of Series A Preferred Shares and Common Shares (which
Series A Preferred Shares and Common Shares shall rank junior to the Series B,
C, D and E Preferred Shares upon liquidation, dissolution or winding-up) shall
then be entitled, to the exclusion of the holders of Series B, C, D and E
Preferred Shares, to share in all the assets of this Corporation thereafter
remaining in accordance with the relative rights and preferences of such
classes.

     (b)  The Series B Preferred Shares shall rank senior to the Series C, D and
E Preferred Shares upon any liquidation, dissolution or winding up of the
Corporation, and no distribution shall be made to the holders of the Series C, D
or E Preferred Shares unless and until the holders of the Series B Preferred
Shares shall have received the full amount due to such holders in accordance
with the rights and preferences of the Series B Preferred Shares upon any
liquidation, dissolution or winding up of the Corporation, and payment to the
holders of the Series B Preferred Shares shall be prior and in preference to the
Series C, D and E Preferred Shares.

     (c)  Neither the consolidation, merger or other business combination of the
Corporation with or into any other individual, firm, corporation or other entity

                                      -3-
<PAGE>
 
(including any successor, by merger or otherwise, of such entity), nor the sale
of all or substantially all of the assets of the Corporation shall be deemed to
be a liquidation, dissolution or winding up of the Corporation for purposes of
this Section 4.

     5.   Conversion to Common Stock.  The Series C, D and E Preferred Shares
shall be convertible into Common Shares of the Corporation as follows:

          5.1  Definitions.  For purposes of this Section 5, the following
definitions shall apply:

          (a)  "Common Stock Equivalents" shall mean Convertible Securities and
rights entitling the holder thereof to receive, directly or indirectly,
additional shares of Common Stock without the payment of any consideration by
such holder for such additional shares of Common Stock or Common Stock
Equivalents.

          (b)  "Common Stock Outstanding" shall mean the aggregate of all Common
Stock outstanding and all Common Stock issuable upon exercise of all outstanding
Options and conversion of all outstanding Convertible Securities.

          (c)  "Conversion Price" shall mean the price, determined pursuant to
this Section 5, at which shares of Common Stock shall be deliverable upon
conversion of Series C, D and E Preferred Stock.

          (d)  "Convertible Securities" shall mean any indebtedness or shares of
stock convertible into or exchangeable for Common Stock, including Series C, D
and E Preferred Shares.

          (e)  "Current Conversion Price" shall mean the Conversion Price
immediately before the occurrence of any event which, pursuant to Section 5.3,
causes an adjustment to the Conversion Price.

          (f)  "Issue Price" of each of the Series C, D and E Preferred Shares
shall be equal to $3.00 per Series C, D and E Preferred Share.

          (g)  "Series C Issuance Date" shall mean the first date on which the
Corporation issues any shares of Series C Preferred Shares.

          (h)  "Option" shall mean any right, warrant or option to subscribe for
or purchase Common Stock or Convertible Securities of the Corporation.

                                      -4-
<PAGE>
 
          5.2  Right to Convert; Initial Conversion Price.

     (a)  Each holder of the Series C, D and E Preferred Shares may, at any 
time, convert any or all of such preferred stock into fully-paid and
nonassessable shares of Common Stock based upon the Conversion Price. Each
Series C, D and E Preferred Share shall be convertible into the number of shares
of Common Stock that results from dividing the Conversion Price in effect for
the respective series at the time of conversion into the Issue Price for the
respective series. The Conversion Price for each of the Series C, D and E
Preferred Shares shall be subject to adjustment from time to time in certain
instances as hereinafter provided.

     (b)  The Conversion Price of the Series C, D and E Preferred Shares shall
initially be equal to $3.00 per Series C, D and E Preferred Share.

     (c)  No adjustments with respect to conversion shall be made on account of
any dividends that may be declared but unpaid on the Series C, D or E Preferred
Shares surrendered for conversion, but no dividends shall thereafter be paid on
the Common Stock unless such unpaid dividends have first been paid to the
holders entitled to payment at the time of conversion of the Series C, D or E
Preferred Shares.

     (d)  Before any holder of Series C, D or E Preferred Shares shall be
entitled to convert the same into Common Stock, the holder shall surrender the
certificate or certificates therefor, duly endorsed, to the office of the
Corporation or any transfer agent for such Series C, D or E Preferred Shares and
shall give written notice to the Corporation at such office that the holder
elects to convert the same.  The Corporation shall, as soon as practicable
thereafter, issue and deliver at such office to such holder of Series C, D and E
Preferred Shares, or to such holder's nominee or nominees, certificates for the
number of full shares of Common Stock to which such holder shall be entitled,
and, if less than all of the shares of Series C, D or E Preferred Shares
represented by such certificate are converted, a certificate representing the
shares of Series C, D and E Preferred Shares not converted.  Such conversion
shall be deemed to have been made as of the date of such surrender of the
certificate for the Series C, D or E Preferred Shares to be converted, and the
person or persons entitled to receive the Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such Common Stock on such date.  If the conversion is in connection with an
offer of securities registered pursuant to the Securities Act of 1933, as
amended, the conversion may, at the option of any holder tendering Series C, D
and E Preferred Shares for conversion, be conditioned upon the closing of the
sale of securities pursuant to such offering, in which event the person(s)
entitled to receive the Common Stock issuable upon such conversion of the Series
C, D or E Preferred Shares shall not be deemed to have converted such Preferred
Shares until immediately prior to the closing of such sale of securities.

          5.3  Adjustments to Conversion Price.  Subject to Section 5.3(h), the
Conversion Price in effect from time to time for Series C, D and E Preferred
Shares shall be subject to adjustment in certain cases as follows:

          (a)  Issuance of Securities.  Subject to Section 5.3(k), with respect
to the Series C, D and E Preferred Shares, in case the Corporation shall at any
time after the Series C Issuance Date issue or sell any Common Stock without
consideration, or for a consideration per share less than the Current Conversion
Price in effect for each of the Series C, D and E Preferred Shares, as the case
may be, then, and thereafter successively upon each such issuance or sale, the
Current Conversion Price for such Series C, Series D or Series E Preferred
Shares shall simultaneously with such issuance or sale be adjusted to a
Conversion Price (calculated to the nearest cent) equal to:

     the Current Conversion Price for such series, multiplied by (ii) a
     fraction, the numerator of which shall be an amount equal to the sum of (a)
     the number of shares of Common Stock Outstanding immediately prior to such
     issuance or sale multiplied by the Current Conversion Price, and (b) the
     total consideration payable to the Corporation upon such issuance or sale
     of such shares and such purchase rights and upon the exercise of such
     purchase rights, and the denominator of which shall be the amount
     determined by multiplying (aa) the number of shares of Common Stock
     Outstanding immediately after such issuance or sale by (bb) the Current
     Conversion Price

provided, however, that the Conversion Price shall at no time exceed $3.00 for
the Series C, D or E Preferred Shares (subject to appropriate adjustment to
reflect stock splits, stock dividends, reorganizations, consolidations and
similar changes hereafter effected).

     For the purposes of this subsection 5.3(a), the following provisions shall
also be applicable:

          (i)  Cash Consideration.  In case of the issuance or sale of 
additional Common Stock for cash, the consideration received by the Corporation
therefor shall be deemed to be the amount of cash received by the Corporation
for such shares (or, if such shares are offered by the Corporation for
subscription, the subscription price, or, if such shares are sold to
underwriters or dealers for public offering without a subscription offering, the
initial public offering price), without deducting therefrom any compensation or
discount paid or allowed to underwriters or dealers or others performing similar
services or for any expenses incurred in connection therewith.

          (ii)  Noncash Consideration.  In case of the issuance (otherwise than
upon conversion or exchange of Convertible Securities) or sale of additional
Common Stock, Options or Convertible Securities for a consideration other than
cash or for consideration a part of which shall be other than cash, the fair
value of

                                      -6-
<PAGE>
 
such consideration as determined by the board of directors of the Corporation in
the good faith exercise of its business judgment, irrespective of the accounting
treatment thereof, shall be deemed to be the value, for purposes of this Section
5, of the consideration other than cash received by the Corporation for such
securities.

          (iii)  Options and Convertible Securities.  In case the Corporation 
shall in any manner issue or grant any Options or any Convertible Securities,
the total maximum number of shares of Common Stock issuable upon the exercise of
such Options or upon conversion or exchange of such Convertible Securities
(regardless of when such Convertible Securities first become convertible or
exchangeable) shall (as of the date of issue or grant of such Options or, in the
case of the issue or sale of Convertible Securities other than where the same
are issuable upon the exercise of Options, as of the date of such issue or sale)
be deemed to be issued and to be outstanding for the purpose of this Section
5.3(a) and to have been issued for the sum of the amount (if any) paid for such
Options or Convertible Securities and the amount (if any) payable upon the
exercise of such Options or upon conversion or exchange of such Convertible
Securities as of the date such securities are first issued regardless of when
such securities first become convertible or exchangeable; provided that, subject
to the provisions of Section 5.3(b), no further adjustment of the Conversion
Price shall be made upon the actual issuance of any such Common Stock or
Convertible Securities or upon the conversion or exchange of any such
Convertible Securities.

          (b)  Change in Option Price or Conversion Rate.  If the purchase price
provided for in any option referred to in subsection 5.3(a)(iii), or the rate at
which any Convertible Securities referred to in subsection 5.3(a)(iii) are
convertible into or exchangeable for shares of Common Stock shall change at any
time (other than under or by reason of provisions designed to protect against
dilution), the Current Conversion Price in effect at the time of such event
shall forthwith be readjusted to the Conversion Price that would have been in
effect at such time had such Options or Convertible Securities still outstanding
provided for such changed purchase price, additional consideration or conversion
rate, as the case may be, at the time initially granted, issued or sold.  If the
purchase price provided for in any such Option referred to in subsection
5.3(a)(iii), or the additional consideration (if any)  payable upon the
conversion or exchange of any Convertible Securities referred to in subsection
5.3(a)(iii), or the rate at which any Convertible Securities referred to in
subsection 5.3(a)(iii) are convertible into or exchangeable for shares of Common
Stock, shall be reduced at any time under or by reason of provisions with
respect thereto designed to protect against dilution, then in case of the
delivery of shares of Common Stock upon the exercise of any such Option or upon
conversion or exchange of any such Convertible Security, the Current Conversion
Price then in effect hereunder shall, upon issuance of such shares of Common
Stock, be adjusted to such amount as would have been obtained had such Option or
Convertible Security never been issued and had adjustments been made only upon
the issuance of the shares of Common Stock delivered as aforesaid and for the
consideration actually received for such Option or Convertible Security and the
Common Stock.

                                      -7-
<PAGE>
 
          (c)  Termination of Option or Conversion Rights.  In the event of the
termination or expiration of any right to purchase Common Stock under any Option
or of any right to convert or exchange Convertible Securities, the Current
Conversion Price shall, upon such termination, be changed to the Conversion
Price that would have been in effect at the time of such expiration or
termination had such Option or Convertible Security, to the extent outstanding
immediately prior to such expiration or termination, never been issued, and the
shares of Common Stock issuable thereunder shall no longer be deemed to be
Common Stock Outstanding.

          (d)  Stock Splits, Dividends, Distributions and Combinations.  If the
Corporation should at any time or from time to time after the Series C Issuance
Date fix a record date for the effectuation of a split or subdivision of the
outstanding shares of Common Stock or the determination of holders of Common
Stock entitled to receive a dividend or other Distribution payable in additional
shares of Common Stock or Common Stock Equivalents, then, following such record
date (or the date of such dividend, Distribution, split or subdivision if no
record date is fixed), the Conversion Price shall be appropriately decreased so
that the number of shares of Common Stock issuable on conversion of each share
of Series C, D and E Preferred Shares shall be increased in proportion to such
increase in the number of outstanding shares of Common Stock (including for this
purpose, Common Stock Equivalents) determined in accordance with Section 5.3(f).
If the number of shares of Common Stock outstanding at any time after the
Issuance Date is decreased by a combination of the outstanding shares of Common
Stock, then, following the record date of such combination, the Conversion Price
shall be appropriately  increased so that the number of shares of Common Stock
issuable on conversion of each share of Series C, Series D and E Preferred
Shares shall be decreased in proportion to such decrease in the number of
outstanding shares of Common Stock.

          (e)  Other Dividends.  If the Corporation shall declare a distribution
payable in securities of other persons, evidences of indebtedness issued by this
Corporation or other persons, assets (excluding cash dividends) or options or
rights not referred to in subsection 5.3(a)(iii), then, in each such case for
the purpose of this Section 5.3(e), the holders of Series C, D and E Preferred
Shares shall be entitled to a proportionate share of any such distribution as
though they were the holders of the number of shares of Common Stock of the
Corporation into which their shares of Series C, D and E Preferred Shares are
convertible as of the record date fixed for the determination of the holders of
Common Stock of the Corporation entitled to receive such distribution.

          (f)  Recapitalizations.  If at any time or from time to time there
shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or a sale of assets transaction provided for elsewhere in
this Section 5) provision shall be made so that the holders of Series C, D and E
Preferred Shares shall thereafter be entitled to receive upon conversion of
shares of Series C, D and E Preferred Shares the number of shares of stock or
other securities or property of the 

                                      -8-
<PAGE>
 
Corporation or otherwise, to which a holder of the number of shares of Common
Stock deliverable upon conversion would have been entitled upon such
recapitalization. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 5 with respect to the rights of
the holders of Series C, D and E Preferred Shares after the recapitalization to
the end that the provisions of this Section 5 (including adjustment of the
Conversion Price then in effect and the number of shares purchasable upon
conversion of shares of Series C, D and E Preferred Shares) shall be applicable
after that event as nearly equivalent as may be practicable to their application
prior to such event.

          (g)  Successive Changes.  The above provisions of this Section 5 shall
similarly apply to successive issuances, changes, sales, dividends or other
distributions, subdivisions and combinations on or of the Common Stock after the
Series C Issuance Date.

          (h)  Other Events Reducing Conversion Price.  Upon the occurrence of
any event not specifically denominated in this Section 5 as altering the
Conversion Price that, in the reasonable exercise of the business judgment of
the Board of Directors, requires, on equitable principles, the reduction of the
Conversion Price, the Conversion Price will be equitably reduced.

          (i)  No Impairment.  The Corporation will not take any action, by
amendment of its Articles of Incorporation, including the filing of a
certificate of designations, or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, the purpose of which, in whole or in
part, is to avoid or seek to avoid the observance or performance of the intents
and purposes of any of the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the intents and purposes of the provisions of this Section 5 and in the
taking of all such action as may be necessary or appropriate in order to protect
the conversion rights of the holders of Series C, D and E Preferred Shares
against impairment.

          (j)  Miscellaneous Conversion Price Matters.  The Corporation shall at
all times reserve and keep available out of its authorized but unissued Common
Stock the full number of shares of Common Stock deliverable upon conversion of
all the then outstanding Series C, D and E Preferred Shares; and shall, at its
own expense, take all such actions and obtain all such permits and orders as may
be necessary to enable the Corporation lawfully to issue such Common Stock upon
the conversion of such Series C, D and E Preferred Shares.

          (k)  Excluded Events.  Notwithstanding anything in this Section 5 to
the contrary, the Conversion Price shall not be adjusted by virtue of (a) the
conversion of shares of Series A, B, C, D or E Preferred Shares into shares of
Common Stock, (b) the repurchase of shares from the Corporation's employees,
consultants, officers or directors at such person's cost (or at such other price
as may 

                                      -9-
<PAGE>
 
be agreed to by the Corporation's board of directors), or (c) the issuance and
sale of, or the grant of options to purchase after the date hereof, an aggregate
of not more than 115,700 shares of Common Stock, or such greater number of
shares of Common Stock as shall be approved by a majority of the Board of
Directors of the Corporation, including the member of the Board of Directors
elected by the holders of the Series C, D and E Preferred Shares pursuant to
Section 3(b) hereof, to employees, advisors, directors, officers or consultants
of the Corporation and its subsidiaries, at a price which is less than the
Conversion Price at the time of such issuance or sale (all as determined in
accordance with this Section 5), and none of such shares shall be included in
any manner in the computation from time to time of the Conversion Price under
subsection 5.3(a) or in the number of Common Shares outstanding for purposes of
such computation.

          (k)  No Fractional Shares.  No fractional shares shall be issued upon
conversion of shares of Series C, D or E Preferred Shares and the number of
shares of Common Stock to be issued shall be rounded to the nearest whole share
determined on the basis of the total number of shares of Series C, D or E
Preferred Shares the holder is at the time converting into Common Stock and the
aggregate number of shares of Common Stock (including the aggregation of all
fractional shares) issuable upon such aggregate conversion.

          (l)  Certificate as to Adjustments.  Upon the occurrence of each
adjustment or readjustment of the Conversion Price pursuant to this Section 5,
the Corporation, at its expense, upon request by any holder of Series C, D or E
Preferred Shares, shall compute such adjustment or readjustment in accordance
with the terms hereof and prepare and furnish to each holder of Series C, D or E
Preferred Shares a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Corporation shall, upon the written request at any time of any holder of
Series C, D or E Preferred Shares, furnish or cause to be furnished to such
holder a like certificate setting forth (a) such adjustment and readjustment,
(b) the Current Conversion Price at the time in effect, and (c) the number of
shares of Common Stock and the amount, if any, of other property which at the
time would be received upon the conversion of a share of any series of Series C,
D or E Preferred Shares.

          5.4  Automatic Conversion.  Immediately upon the effectiveness of the
Corporation's registration statement pursuant to which Common Stock is sold to
the public by the Corporation in a public offering registered under the
Securities Act of 1933, as amended, at a per share public offering price of not
less than $4.00 (subject to appropriate adjustment to reflect stock splits,
stock dividends, reorganizations, consolidations and similar changes hereafter
effected) and an aggregate public offering price greater than or equal to
$5,000,000, each share of Series C, D and E Preferred Shares shall automatically
be converted into shares of Common Stock based upon the applicable Conversion
Price then in effect.  On and after said conversion date, notwithstanding that
any certificates for the shares of Series C, D and E Preferred Shares shall not
have been surrendered for conversion, 

                                     -10-
<PAGE>
 
the shares of such series of Series C, D and E Preferred Shares evidenced
thereby shall be deemed to be no longer outstanding, and all rights with respect
thereto shall forthwith cease and terminate, except only the rights of the
holder (i) to receive the shares of Common Stock to which such holder shall be
entitled upon conversion thereof and (ii) with respect to dividends declared but
unpaid on the Series C, D or E Preferred Shares prior to such conversion date,
to receive such dividends. In the event that any holder of Series C, D or E
Preferred Shares presents such holder's certificate therefor for surrender to
the Corporation or its transfer agent upon such conversion, a certificate for
the number of shares of Common Stock into which the shares of Series C, D or E
Preferred Shares surrendered were convertible on such conversion date promptly
shall be issued and delivered to such holder.

          5.5  Merger; Sale of Corporation.  In the event, after the Series C
Issuance Date, of any proposed consolidation of the Corporation with, or merger
of the Corporation with or into another Corporation (other than a consolidation
or merger in which the Corporation is the continuing Corporation and which does
not result in any reclassification of, or change in, the outstanding shares of
Common Stock), or in case of any proposed sale or transfer to another
Corporation of all or substantially all of the assets of the Corporation, any
holder of Series C, D or E Preferred Shares may elect to have each share of
Series C, D or E Preferred Shares held by such holder treated for all purposes
as if it had been converted into Common Stock on the later of (i) the record
date, if any, for voting by holders of Common Stock on such event and (ii) the
date of such event.

          5.6  Waiver.  The provisions of this Certificate of Designations may
be waived by the written consent of the holders of a majority of the Series C, D
and E Preferred Shares outstanding or subject to outstanding options or warrants
for the purchase of Series C, D or E Preferred Shares.

          IN WITNESS WHEREOF, the undersigned has caused this Certificate of
Designation to be signed on behalf of the Corporation this 25th day of January,
1996.

                                     /s/ Mark Derus

                                RESTATED BYLAWS
                                      OF
                              DERATA CORPORATION

                                  ARTICLE 1.
                                    OFFICES

     1.1)  Offices.  The principal executive office of the corporation shall be
7380 32nd Avenue North, Minneapolis, Minnesota, 55427, and the corporation may
have offices a- such other places within or without the State of Minnesota as
the Board of Directors shall from time to time determine or the business of the
corporation requires.

                                  ARTICLE 2.
                           MEETINGS OF SHAREHOLDERS

     2.1)  Regular Meetings.  Regular meetings of the shareholders of the
corporation entitled to vote shall be held on an annual or other less frequent
basis as shall be determined by the Board of Directors or by the chief executive
officer; provided, that if a regular meeting has not been held during the
immediately preceding 15 months, a shareholder or shareholders holding 3 percent
or more of the voting power of all shares entitled to vote may demand a reguLar
meeting of shareholders by written notice of demand given to an officer of the
corporation.  At each regular meeting, the shareholders, voting as provided in
the Articles of Incorporation and these Bylaws, shall elect qualified successors
for directors who serve for an indefinite term or whose terms have expired or
are due to expire within six months after the date of the meeting, and shall
transact such other business as shall come before the meeting.  No meeting shall
be considered a regular meeting unless specifically designated as such in the
notice of meeting or unless all the shareholders entitled to vote are present in
person or by proxy and none of them objects to such designation.

     2.2)  Special Meetings.  Special meetings of the shareholders entitled to
vote may be called at any time by the Chairman of the Board, the chief executive
officer, the chief financial officer, two or more directors, or a shareholder or
shareholders holding 10 percent or more of the voting power of all shares
entitled to vote.

     2.3)  Place of Meetings.  Meetings of the shareholders shall be held at the
principal executive office of the corporation or at such other place, within or
without the State of Minnesota, as is designated by the Board of Directors,
except that a regular meeting called by or at the demand of a shareholder shall
be held in the county where the principal executive office of the corporation is
located.

     2.4)  Notice of Meetings.  There shall be mailed to each holder of shares
entitled to vote, at his address as shown by the books of the corporation, a
notice setting out the place, date and hour of any regular or special meeting,
which notice 
<PAGE>
 
shall be not less than ten days, unless notice is given by any means in which
delivery is assured within two days in which case the notice may be five days,
nor more than sixty days prior to the date of the meeting; provided, that notice
of a meeting at which there is to be considered a proposal (i) to dispose of
all, or substantially all, of the property and assets of the corporation or (ii)
to dissolve the corporation shall be mailed to all shareholders of record,
whether or not entitled to vote; and provided further, that notice of a meeting
at which there is to be considered a proposal to adopt a plan of merger or
exchange shall be mailed to all shareholders of record, whether or not entitled
to vote, at least fourteen days prior thereto. Notice of any special meeting
shall state the purpose or purposes of the proposed meeting, and the business
transacted at all special meetings shall be confined to the purposes stated in
the notice, unless all of the shareholders are present in person or by proxy and
none of them objects to consideration of a particular item of business.
Attendance at a meeting by any shareholder, without objection by him, shall
constitute his waiver of notice of the meeting.

     2.5)  Quorum and Adjourned Meeting.  The holders of a majority of the 
voting power of the shares entitled to vote at a meeting, represented either in
person or by proxy, shall constitute a quorum for the transaction of business at
any regular or special meeting of shareholders. If a quorum is present when a
duly called or held meeting is convened, the shareholders present may continue
to transact business until adjournment, even though the withdrawal of a number
of shareholders originally present leaves less than the proportion or number
otherwise required for a quorum. In case a quorum is not present at any meeting,
those present shall have the power to-adjourn the meeting from time to time,
without notice other than announcement at the meeting, until the requisite
number of shares entitled to vote shall be represented. At such adjourned
meeting at which the required amount of shares entitled to vote shall be
represented, any business may be transacted which might have been transacted at
the original meeting.

     2.6)  Voting.  At each meeting of the shareholders, every shareholder 
having the right to vote shall be entitled to vote in person or by proxy duly
appointed by an instrument in writing subscribed by such shareholder. Each
shareholder shall have one (1) vote for each share having voting power standing
in his name on the books of the corporation except as may be otherwise provided
in the terms of the share or as may be required to provide for cumulative voting
(if not denied by the Articles). Upon the demand of any shareholder, the vote
for directors or the vote upon any question before the meeting shall be by
ballot. All elections shall be determined and all questions decided by a
majority vote of the number of shares entitled to vote and represented at any
meeting at which there is a quorum except in such cases as shall otherwise be
required by statute, the Articles of Incorporation or these Bylaws. Except as
may otherwise be required to conform to 

                                      -2-
<PAGE>
 
cumulative voting procedures, directors shall be elected by a plurality of the
votes cast by holders of shares entitled to vote thereon.

     2.7)  Record Date.  The Board of Directors may fix a time, not exceeding
sixty days preceding the date of any meeting of shareholders, as a record date
for the determination of the shareholders entitled to notice of and entitled to
vote at such meeting, notwithstanding any transfer of any shares on the books of
the corporation after any record date so fixed.  In the absence of action by the
Board, only shareholders of record twenty days prior to a meeting may vote at
such meeting.

     2.8)  Order of Business.  The suggested order of business at any regular
meeting and, to the extent appropriate, at all other meetings of the
shareholders shall, unless modified by the presiding chairman, be:

     (a)  Call of roll
     (b)  Proof of due notice of meeting or waiver of notice
     (c)  Determination of existence of quorum
     (d)  Reading and disposal of any unapproved minutes
     (e)  Reports of officers and committees
     (f)  Election of directors
     (g)  Unfinished business
     (h)  New business
     (i)  Adjournment.

                                  ARTICLE 3.
                                   DIRECTORS

     3.1)  General Powers.  Except as authorized by the shareholders pursuant to
a shareholder control agreement or unanimous affirmative vote, the business and
affairs of the corporation shall be managed by or under the direction of a Board
of Directors.

     3.2)  Number, Term and Qualifications.  The Board of Directors shall 
consist of not more than nine members, of which at least a majority shall at all
times be persons who are not in the employment of the Company. Until such time
as Article 4 of the corporation's Articles of Incorporation is no longer
effective or is no longer controlling as to the election of directors, the
number of directors and their election shall be controlled by such Article 4.
Thereafter, at each regular meeting, the shareholders shall determine the number
of directors; provided, that between regular meetings the authorized number of
directors may be increased or decreased by the shareholders or increased by the
Board of Directors. Each director shall serve for an indefinite term that
expires at the next regular meeting of shareholders, and until his successor is
elected and qualified, or until his earlier death, resignation,
disqualification, or removal as provided by statute.

                                      -3-
<PAGE>
 
     3.3)  Vacancies.  If not controverted by Article 4 of the corporation's
Articles of Incorporation, vacancies on the Board of Directors may be filled by
the affirmative vote of a majority of the remaining members of the Board, though
less than a quorum; provided, that newly created directorships resulting from an
increase in the authorized number of directors shall be filled by the
affirmative vote of a majority of the directors serving at the time of such
increase.  Persons so elected shall be directors until their successors are
elected by the shareholders, who may make such election at the next regular or
special meeting of the shareholders.

     3.4)  Quorum and Voting.  A majority of the directors currently holding
office shall constitute a quorum for the transaction of business.  Except as
otherwise provided in the Articles of Incorporation or these Bylaws, the acts of
a majority of the directors present at a meeting at which a quorum is present
shall be the acts of the Board of Directors.

     3.5)  Board Meetings; Place and Notice.  Meetings of the Board of Directors
may be held from time to time at any place within or without the State of
Minnesota that the Board of Directors may designate.  In the absence of
designation by the Board of Directors, Board meetings shall be held at the
principal executive office of the corporation, except as may be otherwise
unanimously agreed orally, or in writing, or by attendance.  Any director may
call a Board meeting by giving ten days' notice to all directors of the date and
time of the meeting; a directors' meeting may be called upon five days' notice
if notice is given by any means in which delivery is assumed within two days.
If a meeting schedule is adopted by the Board, or if the date and time of a
Board meeting has been announced at a previous meeting, no notice is required.
The notice need not state the purpose of the meeting, and may be given by mail,
telephone, telegram, or in person.

     3.6)  Absent Directors.  A director may give advance written consent or
opposition to a proposal to be acted on at a Board meeting.  If the director is
not present at the meeting, consent or opposition to a proposal does not
constitute presence for purposes of determining the existence of a quorum, but
consent or opposition shall be counted as a vote in favor of or against the
proposal and shall be entered in the minutes of the meeting, if the proposal
acted on at the meeting is substantially the same or has substantially the same
effect as the proposal to which the director has consented or objected.

     3.7)  Compensation.  Directors who are not salaried officers of the
corporation shall receive such fixed sum per meeting attended or such fixed
annual sum or both as shall be determined from time to time by resolution of the
Board of Directors.  Nothing herein contained shall be construed to preclude any
director from serving this corporation in any other capacity and receiving
proper compensation therefor.

                                      -4-
<PAGE>
 
     3.8)  Committees.  The Board of Directors may, by resolution approved by 
the affirmative vote of a majority of the Board, establish committees having the
authority of the Board in the management of the business of the corporation only
to the extent provided in the resolution.  Each such committee shall consist of
one or more natural persons (who need not be directors) appointed by affirmative
vote of a majority of the directors present, and shall be subject at all times
to the direction and control of the Board.  A majority of the members of a
committee present at a meeting shall constitute a quorum for the transaction of
business.

     3.9)  Order of Business.  The suggested order of business at any meeting of
the Board of Directors shall, to the extent appropriate and unless modified by
the presiding chairman, be:

     (a)  Roll call
     (b)  Proof of due notice of meeting or waiver of notice, or unanimous
          presence and declaration by presiding chairman
     (c)  Determination of existence of quorum
     (d)  Reading and disposal of any unapproved minutes
     (e)  Reports of officers and committees
     (f)  Election of officers
     (g)  Unfinished business

     (i)  Adjournment.

                                  ARTICLE 4.
                                   OFFICERS

the Board, a President, one or more Vice Presidents, a Secretary and a
Treasurer, each of whom shall have the powers, rights, duties and
responsibilities set forth in these Bylaws unless otherwise determined by the
Board.  Any of the offices or functions of those offices may be held by the same
person.  The chief executive officer is authorized to appoint individuals to
divisional type non-executive offices from time to time; provided, that
individuals appointed to such offices shall not be deemed executive officers.

     4.2)  Election, Term of Office and Qualification.  At the first meeting of
the Board following each election of directors, the Board shall elect officers,
who shall hold office until the next election of officers or until their
successors are elected or appointed and qualify; provided, however, that any
officer may be removed with or 

                                      -5-
<PAGE>
 
without cause by the affirmative vote of a majority of the Board of Directors
present (without prejudice, however, to any contract rights of such officer).

     4.3)  Resignation.  Any officer may resign at any time by giving written
notice to the corporation.  The resignation is effective when notice is given to
the corporation, unless a later date is specified in the notice, and acceptance
of the resignation shall not be necessary to make it effective.

     4.4)  Vacancies in Office.  If there be a vacancy in any office of the
corporation, by reason of death, resignation, removal or otherwise, such vacancy
shall be filled for the unexpired term by the Board of Directors.

     4.5)  Chief Executive Officer.  Unless provided otherwise by a resolution
adopted by the Board of Directors, the chief executive officer (a) shall have

which the authority to sign and deliver is required by law to be exercised by
another person or is expressly delegated by the Articles, these Bylaws or the
Board to some other officer or agent of the corporation; (e) may maintain
records of and certify proceedings of the Board and shareholders; and (f) shall
perform such other duties as may from time to time be assigned to him by the

adopted by the Board of Directors, the chief financial officer (a) shall keep

<PAGE>
 
     4.8)  President.  Unless otherwise determined by the Board, the President
shall be the chief executive officer.  If an officer other than the President is
designated chief executive officer, the President shall perform such duties as
may from time to time be assigned to him by the Board.

     4.9)  Vice President.  Each Vice President shall have such powers and shall
perform such duties as may be specified in these Bylaws or prescribed by the
Board of Directors.  In the event of absence or disability of the President, the
Board of Directors may designate a Vice President or Vice Presidents to succeed
to the power and duties of the President.

     4.10)  Secretary.  The Secretary shall, unless otherwise determined by the 
Board, be secretary of and attend all meetings of the shareholders and Board of 
Directors, and may record the proceedings of such meetings in the minute book of
the corporation and, whenever necessary, certify such proceedings.  The

such other duties as may be prescribed by the Board of Directors or the chief
executive officer from time to time.

affirmative vote of a majority of the directors present, an officer elected or
appointed by the Board may delegate in writing some or all of the duties and
powers of his office to other persons.

                                  ARTICLE 5.
                                INDEMNIFICATION

     5.1)  The corporation shall indemnify such persons, for such expenses and
liabilities, in such manner, under such circumstances, and to such extent, as
permitted by Minnesota Statutes, Section 302A.521, as now enacted or hereafter
amended.

                                  ARTICLE 6.
                           SHARES AND THEIR TRANSFER

     6.1)  Certificate of Stock.  Every owner of stock of the corporation stall
be entitled to a certificate, in such form as the Board of Directors may
prescribe, certifying the number of shares of stock of the corporation owned by
him.  The 

                                      -7-
<PAGE>
 
certificates for such stock shall be numbered (separately for each class) in the
order in which they are issued and shall, unless otherwise determined by the
Board, be signed by the chief executive officer, the chief financial officer, or
any other officer of the corporation. A signature upon a certificate may be a
facsimile. Certificates on which a facsimile signature of a former officer,
transfer agent or registrar appears may be issued with the same effect as if he
were such officer, transfer agent or registrar on the date of issue.

     6.2)  Stock Record.  As used in these Bylaws, the term "shareholder" shall
mean the person, firm or corporation in whose name outstanding shares of capital
stock of the corporation are currently registered on the stock record books of
the corporation.  The corporation shall keep, at its principal executive office
or at another place or places within the United States determined by the Board,
a share register not more than one year old containing the names and addresses
of the shareholders and the number and classes of shares held by each
shareholder.  The corporation shall also keep at its principal executive office
or at another place or places within the United States determined by the Board,
a record of the dates on which certificates representing shares were issued.
Every certificate surrendered to the corporation for exchange or transfer shall
be cancelled and no new certificate or certificates shall be issued in exchange
for any existing certificate until such existing certificate shall have been so
cancelled (except as provided for in Section 6.4 of this Article 6).

     6.3)  Transfer of Shares.  Transfer of shares on the books of the
corporation may be authorized only by the shareholder named in the certificate
(or his legal representative or duly authorized attorney-in-fact) and upon
surrender for cancellation of the certificate or certificates for such shares.
The shareholder in whose name shares of stock stand on the books of the
corporation shall be deemed the owner thereof for all purposes as regards the
corporation; provided, that when any transfer of shares shall be made as
collateral security and not absolutely, such fact, if known to the corporation
or to the transfer agent, shall be so expressed in the entry of transfer; and
provided, further, that the Board of Directors may establish a procedure whereby
a shareholder may certify that all or a portion of the shares registered in the
name of the shareholder are held for the account of one or more beneficial
owners.

     6.4)  Lost Certificate.  Any shareholder claiming a certificate of stock to
be lost or destroyed shall make an affidavit or affirmation of that fact in such
form as the Board of Directors may require, and shall, if the directors so
require, give the corporation a bond of indemnity in form and with one or more
sureties satisfactory to the Board of at least double the value, as determined
by the Board, of the stock represented by such certificate in order to indemnify
the corporation against any claim that may be made against it on account of the
alleged loss or destruction of 

                                      -8-
<PAGE>
 
such certificate, whereupon a new certificate may be issued in the same tenor
and for the same number of shares as the one alleged to have been destroyed or
lost.

                                  ARTICLE 7.
                              GENERAL PROVISIONS

     7.1)  Distributions; Acquisitions of Shares.  Subject to the provisions of
law, the Board of Directors may authorize the acquisition of the corporation's
shares and may authorize distributions whenever and in such amounts as, in its
opinion, the condition of the affairs of the corporation shall render it
advisable.

     7.2)  Fiscal Year.  The fiscal year of the corporation shall be established
by the Board of Directors.

     7.3)  Seal.  The corporation shall have such corporate seal or no corporate
seal as the Board of Directors shall from time to time determine.

     7.4)  Securities of Other Corporations.

          (a) Voting Securities Held by the Corporation.  Unless otherwise
     ordered by the Board of Directors, the chief executive officer shall have
     full power and authority on behalf of the corporation (i) to attend and to
     vote at any meeting of security holders of other companies in which the
     corporation may hold securities; (ii) to execute any proxy for such meeting
     on behalf of the corporation; and (iii) to execute a written action in lieu
     of a meeting of such other company on behalf of this corporation.  At such
     meeting, by such proxy or by such writing in lieu of meeting, the chief
     executive officer shall possess and may exercise any and all rights and
     powers incident to the ownership of such securities that the corporation
     might have possessed and exercised if it had been present.  The Board of
     Directors may from time to time confer like powers upon any other person or
     persons.

          (b) Purchase and Sale of Securities.  Unless otherwise ordered by the
     Board of Directors, the chief executive officer shall have full power and
     authority on behalf of the corporation to purchase, sell, transfer or
     encumber securities of any other company owned by the corporation which
     represent not more than 10 percent of the outstanding securities of such
     issue, and may execute and deliver such documents as may be necessary to
     effectuate such purchase, sale, transfer or encumbrance.  The Board of
     Directors may from time to time confer like powers upon any other person or
     persons.

     7.5)  Shareholder Agreements.  In the event of any conflict or 
inconsistency between these Bylaws, or any amendment thereto, and any
shareholder control agreement, whenever adopted, such shareholder control
agreement shall govern.

                                      -9-
<PAGE>
 
                                  ARTICLE 8.
                                   MEETINGS

     8.1)  Waiver of Notice.  Whenever any notice whatsoever is required to be
given by these Bylaws, the Articles of Incorporation or any of the laws of the
State of Minnesota, a waiver thereof given by the person or persons entitled to
such notice, whether before, at or after the time stated therein and either in
writing, orally or by attendance, shall be deemed equivalent to the actual
required notice.

     8.2)  Telephone Meetings and Participation.  A conference among directors 
by any means of communication through which the directors may simultaneously 
hear each other during the conference constitutes a Board meeting, if the same
notice is given of the conference as would be required for a meeting, and if the
number of directors participating in the conference would be sufficient to
constitute a quorum at a meeting. Participation in a meeting by that means
constitutes presence in person at the meeting. A director may participate in a
Board meeting not heretofore described in this paragraph, by any means of
communication through which the director, other directors so participating, and
all directors physically present at the meeting may simultaneously hear each
other during the meeting.  Participation in a meeting by that means constitutes
presence in person at the meeting.  The provisions of this section shall apply
to committees and members of committees to the same extent as they apply to the
Board and directors.

     8.3)  Authorization Without Meeting.  Any action of the shareholders, the
Board of Directors, or any committee of the corporation which may be taken at a
meeting thereof, may be taken without a meeting if authorized by a writing
signed by all of the holders of shares who would be entitled to vote on such
action, by all of the directors (unless less than unanimous action is permitted
by the Articles of Incorporation), or by all of the members of such committee,
as the case may be.

                                  ARTICLE 9.
                             AMENDMENTS OF BYLAWS

     9.1)  Amendments.  Unless the Articles of Incorporation provide otherwise,
these Bylaws may be altered, amended, added to or repealed by the affirmative
vote of a majority of the members of the Board of Directors.  Such authority in
the Board of Directors is subject to the power of the shareholders to change or
repeal such Bylaws, and the Board of Directors shall not make or alter any By
Laws fixing a quorum for meetings of shareholders, prescribing procedures for
removing directors or filling vacancies on the Board, or fixing the number of
directors or their classifications, qualifications or terms of office, but the
Board may adopt or amend a Bylaw to increase the number of directors.

     2.   Method of Exercise; Payment; Issuance of New Warrant.  Subject to
          ----------------------------------------------------             
Paragraph 1 hereof, the purchase right represented by this Warrant may be
exercised by the Holder, in whole or in part and from time to time, by either,
at the election of the Holder, (a) the surrender of this Warrant (with the
notice of exercise form attached hereto as Exhibit A duly executed) at the
principal office of the Company and by the payment to the Company, by check, of
an amount equal to the then applicable Warrant Price per share multiplied by the

satisfactory to the Company for payment to the Company either by check or from
the proceeds of the sale of shares to be sold by the Holder in such public

whose name(s) any certificate(s) representing the Shares shall be issuable upon
exercise of this Warrant shall be deemed to have become the holder(s) of record
of, and shall be treated for all purposes as the record holder(s) of, the shares
represented thereby (and such shares shall be deemed to have been issued)
immediately prior to the close of business on the date or dates upon which this
Warrant is exercised. In the event of any exercise of the rights represented by
this Warrant, certificates for the shares of stock so purchased shall be
delivered to the Holder as soon as possible and in any event within fifteen days
of receipt of such notice and, unless this Warrant has been fully exercised or
expired, a new Warrant representing the portion of the Shares, if any, with
respect to which this Warrant shall not then have been exercised shall also be
issued to the Holder as soon as possible and in any event within such fifteen-
day period. Notwithstanding anything to the contrary contained herein, the
minimum number of Shares as to which this Warrant may be exercised hereunder
shall be the lower of (i) 100,000 Shares or (ii) the remaining number of Shares

          ---------------------------------------                         
issued upon the exercise of the rights represented by this Warrant will, upon
issuance, be fully paid and nonassessable, and free from all preemptive rights,
taxes, liens and charges with respect to the issue thereof; provided that the
Company shall not be required to pay any withholding taxes with respect to the
issue of shares or any transfer taxes with respect to the issue of shares in any
name other than that of the registered holder hereof. During the period within
which the rights represented by 

                                      -2-
<PAGE>
 
this Warrant may be exercised, the Company will at all times have authorized,
and reserved for the purpose of the issue upon exercise of the purchase rights
evidenced by this Warrant, a sufficient number of shares of its Series E
Preferred Stock and the Common Stock of the Company, par value $.01 per share
(the "Common Stock") into which it may be converted to provide for the exercise
(and any subsequent conversion into Common Stock) of the rights represented by
this Warrant. The Company shall at all times take all such action and obtain all
such permits or orders as may be necessary to enable the Company lawfully to
issue such shares of Series E Preferred Stock and the Common Stock into which it
may be converted as duly and validly issued, fully paid and nonassessable shares
upon exercise in full of this Warrant by Holder.

     4.   Adjustment of Warrant Price and Number of Shares.  The number and kind
          ------------------------------------------------                      
of securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the occurrence of
certain events.

          4.1  Definitions.  For purposes of this Warrant, the following

definitions shall apply:

          "Common Stock Equivalents" shall mean Convertible Securities and

          "Current Warrant Price" shall mean the Warrant Price immediately
before the occurrence of any event, which, pursuant to this Warrant, causes an
adjustment to the Warrant Price.

this Warrant, which, as of the date hereof and at all times prior to the
Conversion Date, shall be equal to $4.50 per share, as of the Conversion Date,
shall be determined in accordance with Section 5 and thereafter shall be subject
to adjustment as provided in Section 4.

          4.2  Adjustments to Warrant Price.  Subject to Paragraph 4.2.8, the
               ----------------------------                                  
Warrant Price in effect from time to time shall be subject to adjustment in
certain cases as follows:

               4.2.1  Issuance of Securities.  Subject to Paragraph 4.2.10,
                      ----------------------
in case the Company shall at any time after the Issuance Date issue or sell any
Common Stock without consideration, or for a consideration per share less than
the lower of (a) $3.00 (as adjusted for Recapitalization Events), or (b) the
Current Warrant Price, (such lower amount is referred to as the "Adjustment
Price") then, and thereafter successively upon each such issuance or sale, the
Current Warrant Price shall simultaneously with such issuance or sale be
adjusted and shall be equal to (i) the Current Warrant Price, multiplied by 
(ii) a fraction, the numerator of which shall be an amount equal to the sum of

number of shares of Common Stock Outstanding immediately after such issuance or
sale by (bb) the Adjustment Price; provided, however, that the Warrant Price
                                   --------  -------                        
shall at no time exceed $4.50 (as adjusted for Recapitalization Events).

          For the purposes of this subparagraph 4.2.1, the following provisions
shall also be applicable:

               4.2.1.1  Cash Consideration.  In case, following the Issuance
                        ------------------                                  
Date, of the issuance or sale of additional Common Stock for cash, the
consideration received by the Company therefor shall be deemed to be the amount
of cash received by the Company for such shares (or, if such shares are offered
by the 

                                      -4-
<PAGE>
 
Company for subscription, the subscription price, or, if such shares are sold to
underwriters or dealers for public offering without a subscription offering, the
initial public offering price), without deducting therefrom any compensation or
discount paid or allowed to underwriters or dealers or others performing similar
services or for any expenses incurred in connection therewith.

               4.2.1.2  Non-Cash Consideration.  In case, following the Issuance
                        ----------------------                                  
Date, of the issuance (otherwise than upon conversion or exchange of Convertible
Securities) or sale of additional Common Stock, Options or Convertible
Securities for a consideration other than cash or a consideration a part of
which shall be other than cash, the fair value of such consideration as
determined by the board of directors of the Company in the good faith exercise
of its business judgment, irrespective of the accounting treatment thereof,
shall be deemed to be the value, for purposes of this Paragraph 4, of the
consideration other than cash received by the Company for such securities.

               4.2.1.3  Options and Convertible Securities.  In case, following
                        ----------------------------------       
the Issuance Date, the Company shall in any manner issue or grant any Options or
any Convertible Securities, the total maximum number of shares of Common Stock
issuable upon the exercise of such Options or upon conversion or exchange of
such Convertible Securities (regardless of when such Convertible Securities
first become convertible or exchangeable) shall (as of the date of issue or
grant of such Options or, in the case of the issue or sale of Convertible
Securities other than where the same are issuable upon the exercise of Options,
as of the date of such issue or sale) be deemed to be issued and to be
outstanding for the purpose of this Warrant and to have been issued for the sum
of the amount (if any) paid for such Options or Convertible Securities and the
amount (if any) payable upon the exercise of such Options or upon conversion or
exchange of such Convertible Securities as of the date such securities are first
issued regardless of when such securities first become convertible or
exchangeable; provided that, subject to the provisions of Paragraph 4.2.2, no
further adjustment of the Warrant Price shall be made upon the actual issuance
of any such Common Stock or Convertible Securities or upon the conversion or
exchange of any such Convertible Securities.

               4.2.2  Change in Option Price or Conversion Rate.  If the 
                      -----------------------------------------        
purchase price provided for in any option referred to in subparagraph 4.2.1.3,
or the rate at which any Convertible Securities referred to in subparagraph
4.2.1.3 are convertible into or exchangeable for shares of Common Stock shall
change at any time (other than under or by reason of provisions designed to
protect against dilution), the Current Warrant Price in effect at the time of
such event shall forthwith be readjusted to the Warrant Price that would have
been in effect at such time had such Options or Convertible Securities still
outstanding provided for such changed purchase price, additional consideration
or conversion rate, as the case may be, at the time initially granted, issued or
sold. If the purchase price provided for in any such Option referred to in
subparagraph 4.2.1.3, or the additional consideration (if any) payable upon the
conversion or exchange of any Convertible Securities 

                                      -5-
<PAGE>
 
referred to in subparagraph 4.2.1.3, or the rate at which any Convertible
Securities referred to in subparagraph 4.2.1.3 are convertible into or
exchangeable for shares of Common Stock, shall be reduced at any time under or
by reason of provisions with respect thereto designed to protect against
dilution, then in case of the delivery of shares of Common Stock upon the
exercise of any such Option or upon conversion or exchange of any such
Convertible Security, the Current Warrant Price then in effect hereunder shall,
upon issuance of such shares of Common Stock, be adjusted to such amount as
would have obtained had such Option or Convertible Security never been issued
and had adjustments been made only upon the issuance of the shares of Common
Stock delivered as aforesaid and for the consideration actually received for
such Option or Convertible Security and the Common Stock.

               4.2.3  Termination of Option or Conversion Rights.  In the event
                      ------------------------------------------  
of the termination or expiration of any right to purchase Common Stock under any
Option or of any right to convert or exchange Convertible Securities, the
Current Warrant Price shall, upon such termination, be changed to the Warrant
Price that would have been in effect at the time of such expiration or
termination had such Option or Convertible Security, to the extent outstanding
immediately prior to such expiration or termination, never been issued, and the
shares of Common Stock issuable thereunder shall no longer be deemed to be
Common Stock Outstanding.

               4.2.4  Stock Splits, Dividends, Distributions and Combinations.
                       ------------------------------------------------------- 
If the Company should at any time or from time to time after the Issuance Date
fix a record date for the effectuation of a split or subdivision of the
outstanding shares of Series E Preferred Stock or Common Stock or the
determination of holders of Series E Preferred Stock or Common Stock entitled to
receive a dividend or other distribution payable in additional shares of Series
E Preferred Stock or Common Stock or Common Stock Equivalents, then, following
such record date (or the date of such dividend, distribution, split or
subdivision if no record date is fixed), the Warrant price shall be
appropriately decreased so that the number of shares of Series E Preferred Stock
or Common Stock issuable on exercise of this Warrant shall be increased in
proportion to such increase in the number of outstanding shares of Series E
Preferred Stock or Common Stock (including for this purpose, Common Stock
Equivalents) determined in accordance with Paragraph 4.2. If the number of
shares of Series E Preferred Stock or Common Stock outstanding at any time after
the Issuance Date is decreased by a combination of the outstanding shares of
Series E Preferred Stock or Common Stock, then, following the record date of
such combination, the Warrant Price shall be appropriately increased so that the
number of shares of Series E Preferred Stock or Common Stock issuable on
exercise of this Warrant shall be decreased in proportion to such decrease in
the number of Series E Preferred Stock or outstanding shares of Common Stock.

               4.2.5  Other Dividends.  If the Company, following the Issuance
                      ---------------         
Date, shall declare a distribution payable in securities of other persons,
evidences of indebtedness issued by this corporation or other persons, assets
(excluding cash dividends) or options or rights not referred to in subparagraph
4.2.1.3, then, in each 

                                      -6-
<PAGE>
 
such case for the purpose of this Paragraph 4.2.5, provision shall be made so
that the Holder shall receive upon exercise of this Warrant, in addition to the
Shares receivable thereupon, a proportionate share of any such distribution as
though it were the holder of the number of shares of Series E Preferred Stock or
Common Stock of the Company had this Warrant been exercised as of the record
date fixed for the determination of the holders of Series E Preferred Stock or
Common Stock of the Company entitled to receive such distribution.

               4.2.6  Recapitalizations.  If at any time or from time to time,
                      -----------------                                       
following the Issuance Date, there shall be a recapitalization of the Series E
Preferred Stock or Common Stock (other than a subdivisions, combination or
merger or a sale of assets transaction provided for elsewhere in this Paragraph
4) provision shall be made so that the Holders shall thereafter be entitled to
receive upon exercise of this Warrant the number of shares of stock or other
securities or property of the Company or otherwise, to which a holder of Series
E Preferred Stock or Common Stock deliverable upon exercise of this Warrant
would have been entitled on such recapitalization. In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Paragraph 4 with respect to the rights of the Holders after the
recapitalization to the end that the provisions of this Paragraph 4 (including
adjustment of the Warrant Price then in effect and the number of shares
purchasable upon exercise) shall be applicable after that event as nearly
equivalent as may be practicable to their application prior to such event.

               4.2.7  Successive Changes.  The above provisions of this 
                      ------------------      
Paragraph 4 shall similarly apply to successive issuances, changes, sales, 
dividends or other distributions, subdivisions and combinations on or of the 
Series E Preferred Stock or Common Stock after the Issuance Date.

               4.2.8  Other Events Reducing Warrant Price.  Upon the occurrence
                      -----------------------------------   
of any event not specifically denominated in this Paragraph 4 as altering the
Warrant Price that, in the reasonable exercise of the business judgment of the
Board of Directors, requires, on equitable principles, the reduction of the
Warrant Price, the Warrant Price will be equitably reduced.

               4.2.9  No Impairment.  The Company will not take any action, by
                      -------------                                           
amendment of its Articles of Incorporation, including the filing of a
certificate of designations, or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, the purpose of which, in whole or in
part, is to avoid or seek to avoid the observance or performance of the intents
and purposes any of the terms to be observed or performed hereunder by the
Company, but will at all times in good faith assist in the carrying out of all
the intents and purposes of the provisions of this Paragraph 4 and in the taking
of all such action as may be necessary or appropriate in order to protect the
rights of the Holder against impairment.

               4.2.10  Excluded Events.  Notwithstanding anything in this 
                       ---------------    
Paragraph 4 to the contrary, the Warrant Price shall not be adjusted by virtue
of (a) the conversion of shares of Series A, B, C, D or E Preferred Stock into
shares of Common Stock or the exercise of any option or warrant outstanding on
the date hereof (none of which contain any antidilution provisions), (b) the
repurchase of shares from the Company's employees, consultants, officers or
directors at such person's cost (or at such other price as may be agreed to by
the Company's board of directors), (c) the issuance and sale of, or the grant of
options to purchase following the date hereof, an aggregate of not more than
115,700 shares of Common Stock, or such greater number of shares of Common Stock
as shall be approved by a majority of the Board of Directors of the Company,
including the member of the Board of Directors elected by the holders of the
Company's Series C, D and E Preferred Stock pursuant to the terms of the
Certificate of Designations setting forth the rights and preferences thereof, to
employees, advisors, directors, officers or consultants of the Company and its
subsidiaries at a price which is less than the Adjustment Price at the time of
such issuance or sale (all as determined in accordance with this Paragraph 4)
and none of such shares shall be included in any manner in the computation from
time to time of the Warrant Price under subparagraph 4.2 or in the number of
shares of Common Stock outstanding for purposes of such computation or (d) any
issuance of any Common Stock, any declaration of any distribution or dividend,
any recapitalization or any other event for which an appropriate adjustment in
the Conversion Price of the Series E Preferred Stock shall have been made
pursuant to the terms of the Certificate of Designations setting forth the
rights and preferences of the Series E Preferred Stock.

               4.2.11  Certificate as to Adjustments.  In the case of each 
                       -----------------------------  
adjustment or readjustment of the Warrant Price pursuant to this Paragraph 4,
the Company will promptly compute such adjustment or readjustment in accordance
with the terms hereof and cause a certificate setting forth such adjustment or
readjustment, and showing in detail the facts upon which such adjustment or
readjustment is based to be delivered to the holder of this Warrant. The Company
will upon the written request at any time of the holder of this Warrant, furnish
or cause to be furnished to such holder a certificate setting forth:

               (a)   such adjustment and readjustment;

               (b)   the Warrant Price at the time in effect; and

               (c)   the number of Shares receivable upon the exercise of this
                     Warrant.

     5.   Conversion into Company Stock.  In the event that all of the shares of
          -----------------------------                                         
the Company's outstanding Series E Preferred Stock are converted into shares of
Common Stock pursuant to the Company's Articles of Incorporation prior to the
exercise (in whole or in part) of this Warrant, this Warrant shall automatically
become exercisable for a number of shares of Common Stock that the Holder would

                                      -8-
<PAGE>
 
have received had this Warrant, to the extent not previously exercised in part
prior to such date, been exercised for Series E Preferred Stock immediately
prior to the first date of the Series E Preferred Stock was so converted.  In
the event that this Warrant shall become exercisable for Common Stock, all
references in this Warrant to Series E Preferred Stock shall thereafter be
deemed to mean and include Common Stock.  Upon the automatic conversion of the
Series E Preferred Stock, the Warrant Price shall be recalculated and shall be
equal to (i) $4.50 times the number of shares of Series E Preferred Stock
purchasable immediately prior to the conversion, divided by (ii) the number of
shares of Common Stock that such shares of Series E Preferred Stock would be
converted into upon the conversion thereof as of such date.

     6.   Fractional Shares.  No fractional shares of Series E Preferred Stock
          -----------------                                                   
will be issued in connection with any exercise hereunder, but in lieu of such
fractional shares the Company shall make a cash payment therefor upon the basis
of the current market price of such Shares then in effect as determined in good
faith by the Company's Board of Directors.

     7.   No Privilege of Stock Ownership.  Prior the to exercise of this
          -------------------------------                                
Warrant, the Holder shall not be entitled, by virtue of holding this Warrant, to
any rights of a stockholder of the Company, including (without limitation) the
right to vote, receive dividends or other distributions, or exercise preemptive
rights, and the Holder shall not be entitled to any notice or other
communication concerning the business or affairs of the Company.  Nothing in
this Paragraph 7, however, shall limit the right of the Holder to be provided
the notices described in this Warrant, hereof, or to participate in
distributions described in Paragraph 4 hereof if the Holder ultimately exercises
this Warrant.  Notwithstanding the foregoing, the Company will transmit to the
Holder such information, documents and reports as are generally distributed to
the holders of any class or series of the securities of the Company concurrently
with the distribution thereof to the shareholders.

     8.   Limitation of Liability.  Except as otherwise provided herein, in the
          -----------------------                                              
absence of affirmative action by the Holder hereof to purchase the Shares, no
mere enumeration herein of the rights or privileges of the Holder hereof shall
give rise to any liability of Holder for the purchase price or as a stockholder

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

          9.1  The Company will maintain a register (the "Warrant Register")
containing the name and address of the Holder.  Holder may change its address as
shown on the Warrant Register by written notice to the Company requesting such
change.  Any notice or written communication required or permitted to be given

Holder as the absolute owner of this Warrant for all purposes, notwithstanding
any notice to the contrary.

          9.2  This Warrant shall be non-assignable and otherwise non-
transferable except as specifically permitted and in accordance with the terms
hereof.   Subject to the provisions of this Warrant, specifically including
paragraph 10, and compliance with the Act, title to this Warrant may be
transferred in whole or in part by endorsement (by the Holder executing the
Transfer Form annexed hereto) and delivery in the same manner as a negotiable
instrument transferable by endorsement and delivery at any time after the
termination or expiration of the Development Agreement (as defined in paragraph

Affiliate (as defined in Rule 12b of the Securities Exchange Act of 1934, as
amended) of the Holder, or to a successor or assignee of substantially all of
the Holder's assets or (b) any  transferee who, together with such transferees'
affiliates, (i) does not acquire from the Holder the right to buy in excess of
500,000 shares pursuant to this Warrant or the Option issued on the date hereof
and (ii) acquires not less than the lesser of (A) the right to purchase 100,000
shares of Series E Preferred Stock or Common Stock or (B) the remaining number
of shares subject to the Warrant.  This Warrant may not be transferred or
assigned without compliance with all applicable federal and state securities
laws by the transferor and the transferee (including the delivery of investment
representation letters and legal opinions reasonably satisfactory to the
Company, if such are requested by the Company).

          9.3  On surrender of this Warrant for exchange, properly endorsed on
the Transfer Form and subject to the provisions of this Warrant with respect to
compliance with the Act and with the limitations on assignments and transfers
and contained in this Paragraph 9 and Paragraph 10, the Company at its expense
shall issue to or on the order of the Holder a new warrant or warrants of like
tenor, in the name of the transferee or as the transferee (on payment by the
transferee of any applicable transfer taxes) may direct, or the number of shares
issuable upon exercise hereof.

          9.4  The Holder, by acceptance hereof, acknowledges that this Warrant
and the Shares to be issued upon exercise hereof are being acquired solely for
the Holder's own account and not as a nominee for any other party, and for
investment, and that the Holder will not offer, sell or otherwise dispose of
this Warrant or any Shares to be issued upon exercise hereof except under
circumstances that will not result in a violation of the Act or exercise hereof
except under circumstances that will not result in a violation of the Act or any
state securities laws.  Upon exercise of this Warrant, the Holder shall, if
reasonably requested by the Company, confirm in writing, in a form satisfactory
to the Company, that the Shares so purchased are being acquired solely for the
Holder's own account and not as a nominee for any other party, for investment,
and not with a view toward distribution or resale.

     10.  Right of First Offer.  Prior to making any transfer of all or any
          --------------------                                             
portion of the Warrant, the Holder will first offer to transfer the Warrant or
such portion thereof to the Company by sending notice to the Company of its
intent to transfer the Warrant or a portion thereof.  The Company shall then
have the assignable option, within 30 days following the receipt of such notice,
to offer to purchase all or any portion of the Warrant subject to transfer
referred to in such notice, specifying the purchase price to be paid therefore
and the other material terms of such purchase (the "Offer").  The Holder shall
have a period of 30 days from its receipt of an Offer to determine whether to
accept such Offer.  In the event the Holder determines to accept the Offer, the
closing of the sale of the Warrant (or such portion thereof referred to in the
Offer) shall occur within 45 days of the date the Holder notifies the Company of
its intent to accept the Offer.  In the event the Holder does not accept the
Offer, subject to the terms of Section 9.2, the Holder shall have the right to
transfer the Warrant, or the portion thereof referred to in the notice, on any
terms more favorable than the terms of the Offer, to any person or entity who
enters into a binding agreement with the Holder for such purchase, or who so
purchases the Warrant, or such portion thereof, within 150 days from the date
that either the Holder received the Offer or the expiration of the time in which
the Company had the right to make an Offer.

     11.  Registration Rights.  The holder the Warrant Shares is entitled to

set forth therein) dated January 25, 1996 by and among the Company and Becton

          ----------------------------                                         
corporation succeeding the Company by merger or consolidation and all of the
obligations of the Company relating to the Series E Preferred Stock issuable
upon the exercise or conversion of this Warrant shall survive the exercise,
conversion and termination of this Warrant and all of the covenants and
agreements of the Company shall inure to the benefit of the successors and
assigns of the Holder.  The Company will, at the same time of the exercise or
conversion of this Warrant, in whole or in part, upon request of the Holder but
at the Company's expense, acknowledge in writing its continuing obligation to
the Holder hereof in respect of any rights (including, without limitation, any
right to registration of the shares of Common Stock) to which the Holder hereof
shall continue to be entitled after such exercise or conversion in accordance
with this Warrant; provided, that the failure of the Holder to make any such
request shall not affect the continuing obligation of the Company to the Holder
in respect of such rights.

     14.  Lost Warrants or Stock Certificates.  The Company covenants to the
          -----------------------------------                               
Holder that upon receipt of evidence reasonably satisfactory to the Company of
loss, theft, destruction, or mutilation of this Warrant or any stock certificate
and, in the case of any such loss, theft or destruction, upon receipt of an
indemnity reasonably

                                      -11-
<PAGE>
 
satisfactory to the Company, or in the case of any such mutilation upon

of the lost, stolen, destroyed or mutilated Warrant or stock certificate.

     17.  Amendments and Waivers.  Any term of this Warrant may be amended, and
          ----------------------                                               
the observance of any term of this Warrant may be waived (either generally or in
a particular instance, and either retroactively or prospectively), with the
written consent of the Company and the Holder.  Any such amendment or waiver
shall be binding on the Company and the Holder and any subsequent transferee of
this Warrant.

expired, a new Option representing the portion of the Shares, if any, with
respect to which this Option shall not then have been exercised shall also be
issued to the Holder as soon as possible and in any event within such fifteen-
day period.  Notwithstanding anything to the contrary contained herein, the
minimum number of Shares as to which this Option may be exercised hereunder
shall be the lower of (i) 100,000 


                                      -2-

Shares or (ii) the remaining number of Shares for which this Option may be
exercised.

     3.   Stock Fully Paid; Reservation of Shares.  All Shares that may be
          ---------------------------------------                         
issued upon the exercise of the rights represented by this Option will, upon
issuance, be fully paid and nonassessable, and free from all preemptive rights,
taxes, liens and charges with respect to the issue thereof; provided that the
Company shall not be required to pay any withholding taxes with respect to the
issue of shares or any transfer taxes with respect to the issue of shares in any
name other than that of the registered holder hereof.  During the period within
which the rights represented by this Option may be exercised, the Company will
at all times have authorized, and reserved for the purpose of the issue upon
exercise of the purchase rights evidenced by this Option, a sufficient number of
shares of its Series D Preferred Stock and the Common Stock of the Company, par
value $.01 per share (the "Common Stock"), into which it may be converted to
provide for the exercise (and any subsequent conversion into Common Stock) of
the rights represented by this Option.  The Company shall at all times take all
such action and obtain all such permits or orders as may be necessary to enable
the Company lawfully to issue such shares of Series D Preferred Stock and the
Common Stock into which it may be converted as duly and validly issued, fully
paid and nonassessable shares upon exercise in full of this Option by Holder.

     4.   Adjustment of Option Price and Number of Shares.  The number and kind
          -----------------------------------------------                      
of securities purchasable upon the exercise of this Option and the Option Price
shall be subject to adjustment from time to time upon the occurrence of certain
events.

          4.1  Definitions.  For purposes of this Option, the following
               -----------                                             
definitions shall apply:

               "Common Stock Equivalents" shall mean Convertible Securities and
rights entitling the holder thereof to receive, directly or indirectly,
additional shares of Common Stock without the payment of any consideration by
such holder for such additional shares of Common Stock or Common Stock
Equivalents.

               "Common Stock Outstanding" shall mean the aggregate of all Common
Stock outstanding and all Common Stock issuable upon exercise of all outstanding
Options and conversion of all outstanding Convertible Securities.

               "Convertible Securities" shall mean any indebtedness or shares of
stock convertible into or exchangeable for Common Stock, including, without
limitation, Series A, Series B, Series C, Series D and Series E Preferred Stock.



                                      -3-
<PAGE>
 
               "Conversion Date" shall mean the date the Series D Preferred
Stock is automatically converted into Common Stock pursuant to the terms of the
Certificate of Designations setting forth the rights and preferences of the
Series D Preferred Stock.


               "Current Option Price" shall mean the Option Price immediately
before the occurrence of any event, which, pursuant to this Option, causes an
adjustment to the Option Price.

               "Issuance Date" shall mean the date hereof.

               "Option Price" shall mean the price, determined pursuant to this
Option, at which shares of Common Stock shall be deliverable upon exercise of
this Option.

               "Options" shall mean any rights, warrants or options to subscribe
for or purchase Common Stock or Convertible Securities.

               "Recapitalization Events" shall mean stock splits, stock
dividends, recapitalizations, reclassifications and similar events.

          4.2  Adjustments to Option Price.  Subject to Paragraph 4.2.8, the
               ---------------------------                                  
Option Price in effect from time to time shall be subject to adjustment in
certain cases as follows:

               4.2.1 Issuance of Securities. Subject to Paragraph 4.2.10, in
case the Company shall at any time after the Issuance Date issue or sell any
Common Stock without consideration, or for a consideration per share less than
the lower of (a) $3.00 (as adjusted for Recapitalization Events), or (b) the
Current Option Price (such lower amount is referred to as the "Adjustment
Price"), then, and thereafter successively upon each such issuance or sale, the
Current Option Price shall simultaneo usly with such issuance or sale be
adjusted and shall be equal to (i) the Current Option Price, multiplied by (ii)
a fraction, the numerator of which shall be an amount equal to the sum of (a)
the number of shares of Common Stock Outstanding immediately prior to such
issuance or sale multiplied by the Adjustment Price, and (b) the total
consideration payable to the Company upon such issuance or sale of such shares
and such purchase rights and upon the exercise of such purchase rights, and the
denominator of which shall be the amount determined by multiplying (aa) the
number of shares of Common Stock Outstanding immediately after such issuance by
(bb) the Adjustment Price; provided, however, that the Option Price shall at no
                           --------  -------
time exceed $3.50 (as adjusted for Recapitalization Events).



                                      -4-
<PAGE>
 
     For the purposes of this subparagraph 4.2.1, the following provisions
shall also be applicable:

          4.2.1.1  Cash Consideration.  In case, following the Issuance Date, of
                   ------------------                                           
the issuance or sale of additional Common Stock for cash, the consideration
received by the Company therefor shall be deemed to be the amount of cash
received by the Company for such shares (or, if such shares are offered by the
Company for subscription, the subscription price, or, if such shares are sold to
underwriters or dealers for public offering without a subscription offering, the
initial public offering price), without deducting therefrom any compensation or
discount paid or allowed to underwriters or dealers or others performing similar
services or for any expenses incurred in connection therewith.

          4.2.1.2  Non-Cash Consideration.  In case, following the Issuance
                   ----------------------                                  
Date, of the issuance (otherwise then upon conversion or exchange of Convertible
Securities) or sale of additional Common Stock, Options or Convertible
Securities for a consideration other than cash or a consideration a part of
which shall be other than cash, the fair value of such consideration as
determined by the board of directors of the Company in the good faith exercise
of its business judgment, irrespective of the accounting treatment thereof,
shall be deemed to be the value, for purposes of this Paragraph 4, of the
consideration other than cash received by the Company for such securities.

          4.2.1.3  Options and Convertible Securities.  In case, following the
                   ----------------------------------                         
Issuance Date, the Company shall in any manner issue or grant any Options or any
Convertible Securities, the total maximum number of shares of Common Stock
issuable upon the exercise of such Options or upon conversion or exchange of
such Convertible Securities (regardless of when such Convertible Securities
first become convertible or exchangeable) shall (as of the date of issue or
grant of such Options or, in the case of the issue or sale of Convertible
Securities other than where the same are issuable upon the exercise of Options,
as of the date of such issue or sale) be deemed to be issued and to be
outstanding for the purpose of this Option and to have been issued for the sum
of the amount (if any) paid for such Options or Convertible Securities and the
amount (if any) payable upon the exercise of such Options or upon conversion or
exchange of such Convertible Securities as of the date such securities are first
issued regardless of when such securities first become convertible or
exchangeable; provided that, subject to the provisions of Paragraph 4.2.2, no
further adjustment of the Option Price shall be made upon the actual issuance of
any such Common Stock or Convertible Securities or upon the conversion or
exchange of any such Convertible Securities.



                                      -5-
<PAGE>
 
          4.2.2  Change in Option Price or Conversion Rate.  If the purchase
                 -----------------------------------------                  
price provided for in any option referred to in subparagraph 4.2.1.3, or the
rate at which any Convertible Securities referred to in subparagraph 4.2.1.3 are
convertible into or exchangeable for shares of Common Stock shall change at any
time (other than under or by reason of provisions designed to protect against
dilution), the Current Option Price in effect at the time of such event shall
forthwith be readjusted to the Option Price that would have been in effect at
such time had such Options or Convertible Securities still outstanding provided
for such changed purchase price, additional consideration or conversion rate, as
the case may be, at the time initially granted, issued or sold.  If the purchase
price provided for in any such Option referred to in subparagraph 4.2.1.3, or
the additional consideration (if any) payable upon the conversion or exchange of
any Convertible Securities referred to in subparagraph 4.2.1.3, or the rate at
which any Convertible Securities referred to in subparagraph 4.2.1.3 are
convertible into or exchangeable for shares of Common Stock, shall be reduced at
any time under or by reason of provisions with respect thereto designed to
protect against dilution, then in case of the delivery of shares of Common Stock
upon the exercise of any such Option or upon conversion or exchange of any such
Convertible Security, the Current Option Price then in effect hereunder shall,
upon issuance of such shares of Common Stock, be adjusted to such amount as
would have obtained had such Option or Convertible Security never been issued
and had adjustments been made only upon the issuance of the shares of Common
Stock delivered as aforesaid and for the consideration actually received for
such Option or Convertible Security and the Common Stock.

          4.2.3  Termination of Option or Conversion Rights.  In the event of
                 ------------------------------------------                  
the termination or expiration of any right to purchase Common Stock under any
Option or of any right to convert or exchange Convertible Securities, the
Current Option Price shall, upon such termination, be changed to the Option
Price that would have been in effect at the time of such expiration or
termination had such Option or Convertible Security, to the extent outstanding
immediately prior to such expiration or termination, never been issued, and the
shares of Common Stock issuable thereunder shall no longer be deemed to be
Common Stock Outstanding.

          4.2.4  Stock Splits, Dividends, Distributions and Combinations.  If
                 -------------------------------------------------------     
the Company should at any time or from time to time after the Issuance Date fix
a record date for the effectuation of a split or subdivision of the outstanding
shares of Series D Preferred Stock or Common Stock or the determination of
holders of Series D Preferred Stock or Common Stock entitled to receive a
dividend or other distribution payable in additional shares of Series D
Preferred Stock or Common Stock or Common Stock Equivalents, then, following
such record date (or the date of such dividend, Distribution, split or
subdivision if no record date is fixed), the Option Price shall be appropriately
decreased so that the number of shares of Series D Preferred Stock or Common
Stock issuable on exercise of this Option shall be increased in proportion to
such increase in the number of outstanding shares of 



                                      -6-
<PAGE>
 
Series D Preferred Stock or Common Stock (including for this purpose, Common
Stock Equivalents) determined in accordance with Paragraph 4.2. If the number of
shares of Series D Preferred Stock or Common Stock outstanding at any time after
the Issuance Date is decreased by a combination of the outstanding shares of
Series D Preferred Stock or Common Stock, then, following the record date of
such combination, the Option Price shall be appropriately increased so that the
number of shares of Series D Preferred Stock or Common Stock issuable on
exercise of this Option shall be decreased in proportion to such decrease in the
number of outstanding shares of Series D Preferred Stock or Common Stock.

          4.2.5  Other Dividends.  If the Company, following the Issuance Date,
                 ---------------                                               
shall declare a distribution payable in securities of other persons, evidences
of indebtedness issued by this corporation or other persons, assets (excluding
cash dividends) or options or rights not referred to in subparagraph 4.2.1.3,
then, in each such case for the purpose of this Paragraph 4.2.5, provision shall
be made so that the Holder shall receive upon exercise of this Option, in
addition to the Shares receivable thereupon, a proportionate share of any such
distribution as though it were the holder of the number of shares of Series D
Preferred Stock or Common Stock of the Company had this Option been exercised as
of the record date fixed for the determination of the holders of Series D
Preferred Stock or Common Stock of the Company entitled to receive such
distribution.

          4.2.6  Recapitalizations.  If at any time or from time to time,
                 -----------------                                       
following the Issuance Date, there shall be a recapitalization of the Series D
Preferred Stock or Common Stock (other than a subdivision, combination or merger
or a sale of assets transaction provided for elsewhere in this Paragraph 4)
provision shall be made so that the Holders shall thereafter be entitled to
receive upon exercise of this Option the number of shares of stock or other
securities or property of the Company or otherwise, to which a holder of Series
D Preferred Stock or Common Stock deliverable upon exercise of this Option would
have been entitled on such recapitalization.  In any such case, appropriate
adjustment shall be made in the application of the provisions of this Paragraph
4 with respect to the rights of the Holders after the recapitalization to the
end that the provisions of this Paragraph 4 (including adjustment of the Option
Price then in effect and the number of shares purchasable upon exercise) shall
be applicable after that event as nearly equivalent as may be practicable to
their application prior to such event.

          4.2.7  Successive Changes.  The above provisions of this Paragraph 4
                 ------------------                                           
shall similarly apply to successive issuances, changes, sales, dividends or
other distributions, subdivisions and combinations on or of the Series D
Preferred Stock or Common Stock after the Issuance Date.

          4.2.8.  Other Events Reducing Option Price.  Upon the occurrence of
                  ----------------------------------                         
any event not specifically denominated in this Paragraph 4 as altering the
Option 



                                      -7-
<PAGE>
 
Price that, in the reasonable exercise of the business judgment of the
Board of Directors, requires on equitable principles, the reduction of the
Option Price, the Option Price will be equitably reduced.

               4.2.9.  No Impairment.  The Company will not take any action, by
               ---------------------                                           
amendment of its Articles of Incorporation, including the filing of a
certificate of designations, or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, the purpose of which, in whole or in
part, is to avoid or seek to avoid the observance or performance of the intents
and purposes any of the terms to be observed or performed hereunder by the
Company, but will at all times in good faith assist in the carrying out of all
the intents and purposes of the provisions of this Paragraph 4 and in the taking
of all such action as may be necessary or appropriate in order to protect the
rights of the Holder against impairment.

          4.2.10  Excluded Events.  Notwithstanding anything in this Paragraph 4
                  ---------------                                               
to the contrary, the Option Price shall not be adjusted by virtue of (a) the
conversion of shares of Series A, B, C, D or E Preferred Stock into shares of
Common Stock or the exercise of any option or warrant outstanding on the date
hereof (none of which contain any antidilution provisions), (b) the repurchase
of shares from the Company's employees, consultants, officers or directors at
such person's cost (or at such other price as may be agreed to by the Company's
board of directors), (c) the issuance and sale of, or the grant of options to
purchase following the date hereof, an aggregate of not more than 115,700 shares
of Common Stock, or such greater number of shares of Common Stock as shall be
approved by a majority of the Board of Directors of the Company, including the
member of the Board of Directors elected by the holders of the Company's Series
C, D and E Preferred Stock pursuant to the terms of the Certificate of
Designations setting forth the rights and preferences thereof, to employees,
advisors, directors, officers or consultants of the Company and its subsidiaries
at a price which is less than the Adjustment Price at the time of such issuance
or sale (all as determined in accordance with this Paragraph 4), and none of
such shares shall be included in any manner in the computation from time to time
of the Option Price under subparagraph 4.2 or in the number of shares of Common
Stock outstanding for purposes of such computation or (d) any issuance of any
Common Stock, any declaration or payment of any distribution or dividend, any
recapitalization or any other event for which an appropriate adjustment in the
Conversion Price of the Series D Preferred Stock shall have been made pursuant
to the terms of the Certificate of Designations setting forth the rights and
preferences of the Series D Preferred Stock.

          4.2.11  Certificate as to Adjustments.  In the case of each adjustment
                  -----------------------------                                 
or readjustment of the Option Price pursuant to this Paragraph 4, the Company
will promptly compute such adjustment or readjustment in accordance with the
terms hereof and cause a certificate setting forth such adjustment or



                                      -8-
<PAGE>
 
readjustment, and showing in detail the facts upon which such adjustment or
readjustment is based to be delivered to the holder of this Option.  The Company
will, upon the written request at any time of the holder of this Option, furnish
or cause to be furnished to such holder a certificate setting forth:

               (a) such adjustments and readjustments;

               (b) the Option Price at the time in effect; and

               (c) the number of Shares receivable upon the exercise of this
                   Option.

          5.   Conversion into Common Stock.  In the event that all of the
               ----------------------------                               
shares of the Company's outstanding Series D Preferred Stock are converted into
shares of Common Stock pursuant to the Company's Articles of Incorporation prior
to the exercise (in whole or in part) of this Option, this Option shall
automatically become exercisable for a number of shares of Common Stock that the
Holder would have received had this Option, to the extent not previously
exercised in part prior to such date, been exercised for Series D Preferred
Stock immediately prior to the first date the Series D Preferred Stock was so
converted.  In the event that this Option shall become exercisable for Common
Stock, all references in this Option to Series D Preferred Stock shall
thereafter be deemed to mean and include Common Stock.  Upon the automatic
conversion of the Series D Preferred Stock, the Option Price shall be
recalculated and shall be equal to (i) $3.50 times the number of shares of
Series D Preferred Stock purchasable immediately prior to the conversion,
divided by (ii) the number of shares of Common Stock that such shares of Series
D Preferred Stock would be converted into upon the conversion thereof as of such
date.

          6.   Fractional Shares.  No fractional shares of Series D Preferred
               -----------------                                             
Stock will be issued in connection with any exercise hereunder, but in lieu of
such fractional shares the Company shall make a cash payment therefor upon the
basis of the current market price of such Shares then in effect as determined in
good faith by the Company's Board of Directors.

          7.   No Privilege of Stock Ownership.  Prior to the exercise of this
               -------------------------------                                
Option, the Holder shall not be entitled, by virtue of holding this Option, to
any rights of a stockholder of the Company, including (without limitation) the
right to vote, receive dividends or other distributions, or exercise preemptive
rights, and the Holder shall not be entitled to any notice or other
communication concerning the business or affairs of the Company.  Nothing in
this Paragraph 7, however, shall limit the right of the Holder to be provided
the notices described in this Option, hereof, or to participate in distributions
described in Paragraph 4 hereof if the Holder ultimately exercises this Option.
Notwithstanding the foregoing, the Company will transmit to the Holder such
information, documents and reports as are generally 



                                      -9-
<PAGE>
 
distributed to the holders of any class or series of the securities of the
Company concurrently with the distribution thereof to the shareholders.

          8.   Limitation of Liability.  Except as otherwise provided herein, in
               -----------------------                                          
the absence of affirmative action by the Holder hereof to purchase the Shares,
no mere enumeration herein of the rights or privileges of the Holder hereof
shall give rise to any liability of Holder for the purchase price or as a
stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.

          9.   Transfer of Option.
               ------------------ 

               9.1       The Company will maintain a register (the "Option
Register") containing the name and address of the Holder. Holder may change its
address as shown on the Option Register by written notice to the Company
requesting such change. Any notice or written communication required or
permitted to be given to the Holder may be delivered or given by mail to Holder
as shown on the Option Register and at the address shown on the Option Register.
Until this Option is transferred on the Option Register of the Company, the
Company may treat the Holder as the absolute owner of this Option for all
purposes, notwithstanding any notice to the contrary.

              9.2       This Option shall be non-assignable and otherwise non-
transferable except as specifically permitted and in accordance with the terms
hereof.   Subject to the provisions of this Option, specifically including
paragraph 10, and compliance with the Act, title to this Option may be
transferred in whole or in part by endorsement (by the Holder executing the
Transfer Form annexed hereto) and delivery in the same manner as a negotiable
instrument transferable by endorsement and delivery at any time after the
termination or expiration of the Development Agreement (as defined in paragraph
1), provided that this Option shall not be transferable other than to (a) an
    -------- ----                                                           
Affiliate (as defined in Rule 12b of the Securities Exchange Act of 1934, as
amended) of the Holder, or to a successor or assignee of substantially all of
the Holder's assets or (b) any transferee who, together with such transferees'
affiliates, (i) does not acquire from the Holder the right to buy in excess of
500,000 shares pursuant to this Option or the Warrant issued on the date hereof
and (ii) acquires not less than the lesser of (A) the right to purchase 100,000
shares of Series D Preferred Stock or Common Stock or (B) the remaining number
of shares subject to the Option.  This Option may not be transferred or assigned
without compliance with all applicable federal and state securities laws by the
transferor and the transferee (including the delivery of investment
representation letters and legal opinions reasonably satisfactory to the
Company, if such are requested by the Company).



                                     -10-
<PAGE>
 
          9.3       On surrender of this Option for exchange, properly endorsed
on the Transfer Form and subject to the provisions of this Option with respect
to compliance with the Act and with the limitations on assignments and transfers
and contained in this Paragraph 9 and Paragraph 10, the Company at its expense
shall issue to or on the order of the Holder a new option or options of like
tenor, in the name of the transferee or as the transferee (on payment by the
transferee of any applicable transfer taxes) may direct, for the number of
shares issuable upon exercise hereof.

          9.4       The Holder, by acceptance hereof, acknowledges that this
Option and the Shares to be issued upon exercise hereof are being acquired
solely for the Holder's own account and not as a nominee for any other party,
and for investment, and that the Holder will not offer, sell or otherwise
dispose of this Option or any Shares to be issued upon exercise hereof except
under circumstances that will not result in a violation of the Act or any state
securities laws.  Upon exercise of this Option, the Holder shall, if reasonably
requested by the Company, confirm in writing, in a form satisfactory to the
Company, that the Shares so purchased are being acquired solely for the Holder's
own account and not as a nominee for any other party, for investment, and not
with a view toward distribution or resale.

          10.  Right of First Offer.  Prior to making any transfer of all or any
               --------------------                                             
portion of the Option, the Holder will first offer to transfer the Option or
such portion thereof to the Company by sending notice to the Company of its
intent to transfer the Option or a portion thereof.  The Company shall then have
the assignable option, within 30 days following the receipt of such notice, to
offer to purchase all or any portion of the Option subject to transfer referred
to in such notice, specifying the purchase price to be paid therefore and the
other material terms of such purchase (the "Offer").  The Holder shall have a
period of 30 days from its receipt of an Offer to determine whether to accept
such Offer.  In the event the Holder determines to accept the Offer, the closing
of the sale of the Option (or such portion thereof referred to in the Offer)
shall occur within 45 days of the date the Holder notifies the Company of its
intent to accept the Offer.  In the event the Holder does not accept the Offer,
subject to the terms of Section 9.2, the Holder shall have the right to transfer

                             MEDI-JECT CORPORATION

                         COMMON STOCK PURCHASE WARRANT


     Medi-Ject Corporation, a Minnesota corporation (the "Company"), hereby
agrees that, for value received, Robert Fullerton, Minneapolis, Minnesota, or
his assigns, is entitled, subject to the terms set forth below, to purchase from
the Company at any time or from time to time after March 23, 1996, and before
5:00 p.m., Minneapolis, Minnesota time, on March 24, 2000, Two Thousand (2,000)
shares of the Common Stock of the Company (the "Common Stock"), at an exercise
price of $2.50 per share, subject to adjustment as provided herein.

     1.  Exercise of Warrant.  The purchase rights granted by this Warrant shall
         -------------------                                                    
be exercised (in minimum quantities of 1,000 shares, or such smaller number of
shares as are exercisable under the Warrant) by the holder surrendering this
Warrant with the form of exercise attached hereto duly executed by such holder,
to the Company at its principal office, accompanied by payment, in cash or by
cashier's check payable to the order of the Company, of the purchase price
payable in respect of the Common Stock being purchased.  If less than all of the
Common Stock purchasable hereunder is purchased, the Company will, upon such
exercise, execute and deliver to the holder hereof a new Warrant (dated the date
hereof) evidencing the number of shares of Common Stock not so purchased.  As
soon as practicable after the exercise of this Warrant and payment of the
purchase price, the Company will cause to be issued in the name of and delivered
to the holder hereof, or as such holder may direct, a certificate or
certificates representing the shares purchased upon such exercise.  The Company
may require that such certificate or certificates contain on the face thereof a
legend substantially as follows:

     "No sale, offer to sell or transfer of the shares represented by this
     certificate shall be made unless a Registration Statement under the Federal
     Securities Act of 1933, as amended (the "Act"), with respect to such shares
     is then in effect or an exemption from the registration requirements of the
     Act is then in fact applicable to such shares."

     2.  Negotiability and Transfer.  This Warrant is issued upon the following
         --------------------------                                            
terms, to which each holder hereof consents and agrees:

          (a) Except where directed by a court of competent jurisdiction
              pursuant to the dissolution or liquidation of a corporate holder
              hereof, for one (1) year from March 24, 1995, title to this
              Warrant may be transferred only to Delphi Financial Corp. (the
              "Agent"), or to a person who is both an officer and shareholder,
              or both an officer and employee, or a registered representative,
              of the Agent, or to a successor (or both an officer and
              shareholder, or both an officer and employee, or both an employee
              and registered representative of the successor) in interest to the
              business of the Agent, by endorsement (by the holder hereof
              executing the form of assignment attached hereto) and delivery in
              the same manner as in the case of a negotiable instrument
              transferable by endorsement and delivery.  

          (b) Until this Warrant is duly transferred on the books of the
              Company, the Company may treat the registered holder of this
              Warrant as absolute owner hereof for all purposes without being
              affected by any notice to the contrary.

          (c) Each successive holder of this Warrant, or of any portion of the
              rights represented thereby, shall be bound by the terms and 
              conditions set forth herein.
<PAGE>
 
     3.   Antidilution Adjustments.  If the Company shall at any time hereafter
          ------------------------                                             
subdivide or combine its outstanding shares of Common Stock, or declare a
dividend payable in Common Stock, the exercise price in effect immediately prior
to the subdivision, combination or record date for such dividend payable in
Common Stock shall forthwith be proportionately increased, in the case of
combination, or proportionately decreased, in the case of subdivision or
declaration of a dividend payable in Common Stock, and each share of Common
Stock purchasable upon exercise of this Warrant, immediately preceding such
event, shall be changed to the number determined by dividing the then current
exercise price by the exercise price as adjusted after such subdivision,
combination or dividend payable in Common Stock.

     No fractional shares of Common Stock are to be issued upon the exercise of
the Warrant, but the Company shall pay a cash adjustment in respect of any
fraction of a share which would otherwise be issuable in an amount equal to the
same fraction of the market price per share of Common Stock on the day of
exercise as determined in good faith by the Company.

     In case of any capital reorganization or any reclassification of the shares
of Common Stock of the Company, or in the case of any consolidation with or
merger of the Company into or with another corporation, or the sale of all or
substantially all of its assets to another corporation, which is effected in
such a manner that the holders of Common Stock shall be entitled to receive
stock, securities or assets with respect to or in exchange for Common Stock,
then, as a part of such reorganization, reclassification, consolidation, merger
or sale, as the case may be, lawful provision shall be made so that the holder
of the Warrant shall have the right thereafter to receive, upon the exercise
hereof, the kind and amount of shares of stock or other securities or property
which the holder would have been entitled to receive if, immediately prior to
such reorganization, reclassification, consolidation, merger or sale, the holder
had held the number of shares of Common Stock which were then purchasable upon
the exercise of the Warrant.  In any such case, appropriate adjustment (as
determined in good faith by the Board of Directors of the Company) shall be made
in the application of the  provisions set forth herein with respect to the
rights and interest thereafter of the holder of the Warrant, to the end that the
provisions set forth herein (including provisions with respect to adjustments of
the exercise price) shall thereafter be applicable, as nearly as reasonably may
be, in relation to any shares of stock or other property thereafter deliverable
upon the exercise of the Warrant.

     When any adjustment is required to be made in the exercise price, initial
or adjusted, the Company shall forthwith determine the new exercise price, and

     (a) prepare and retain on file a statement describing in reasonable detail
         the method used in arriving at the new exercise price; and

     (b) cause a copy of such statement to be mailed to the holder of the
         Warrant as of a date within ten (10) days after the date when the 
         circumstances giving rise to the adjustment occurred.

     4.   Registration Rights.  Prior to making any disposition of the Warrant
          -------------------                                                 
or of any Common Stock purchased upon exercise of the Warrant, the holder will
give written notice to the Company describing briefly the manner of any such
proposed disposition.  The holder will not make any such disposition until (i)
if requested, the Company has been provided an opinion by counsel for the holder
that registration under the Act is not required with respect to such
disposition, or (ii) a Registration Statement covering the proposed distribution
has been filed and has become effective.  The holder then will make any
disposition only pursuant to the conditions of such opinion or registration.
The Company agrees that, upon receipt of written notice from the holder hereof
with respect to such proposed distribution, it will cooperate in providing the
holder with information necessary to make such determination.

     If, at any time prior to the expiration of seven (7) years from March 24,
1995, the Company shall propose to file any Registration Statement (other than
any registration on Forms S-4, S-8 or any 
<PAGE>
 
other similarly inappropriate form or Registration Statement with respect to an
initial public offering in which there are no selling shareholders) under the
Securities Act of 1933, as amended, covering a public offering of the Company's
Common Stock, it will notify the holder hereof at least forty-five (45) days
prior to each such filing and will include in the Registration Statement (to the
extent permitted by applicable regulation) the Common Stock purchased by the
holder or purchasable by the holder upon the exercise of the Warrant to the
extent requested by the holder hereof, in writing, within twenty (20) days of
the holder's receipt of such notice from the Company. Notwithstanding the
foregoing, the number of shares of the holders of the Warrants proposed to be
registered thereby shall be reduced pro rata with any other selling shareholder
(other than the Company) upon the request of the managing underwriter of such
offering. If the Registration Statement or Offering Statement filed pursuant to
such forty-five (45) day notice has not become effective within six months
following the date such notice is given to the holder hereof, the Company must
again notify such holder in the manner provided above.

     All expenses of any such registrations referred to in this Section 4,
except the fees of counsel to such holders and underwriting commissions or
discounts, filing fees, and any transfer or other taxes applicable to such
shares, shall be borne by the Company.

     The Company will furnish the holder hereof with a reasonable number of
copies of any prospectus included in such filings and will amend or supplement
the same as required during the period of required use thereof.

     In the case of the filing of any Registration Statement, and to the extent
permissible under the Securities Act of 1933, as amended, and controlling
precedent thereunder, the Company and the holder hereof shall provide cross
indemnification agreements to each other in customary scope covering the
accuracy and completeness of the information furnished by each.

     The holder of the Warrant agrees to cooperate with the Company in the
preparation and filing of any such Registration Statement or Offering Statement,
and in the furnishing of information concerning the holder for inclusion
therein, or in any efforts by the Company to establish that the proposed sale is
exempt under the Act as to any proposed distribution.

     5.   Right to Convert.
          ---------------- 

          (a) If the Company's Common Stock is traded on an exchange or is
              quoted on the National Association of Securities Dealers, Inc.
              ("NASDAQ") Automated Quotation National Market System or Small-Cap
              System or is traded in the over-the-counter market, then the
              holder of this Warrant shall have the right to require the Company
              to convert this Warrant (the "Conversion Right"), at any time
              prior to its expiration, into shares of Common Stock as provided
              for in this Section 5. Upon exercise of the Conversion Right, the
              Company shall deliver to the holder (without payment by the holder
              of any exercise price) that number of shares of Common Stock equal
              to the quotient obtained by dividing (x) the value of the Warrant
              at the time the Conversion Right is exercised (determined by
              subtracting the aggregate exercise price for the Warrant Common
              Stock in effect immediately prior to the exercise of the
              Conversion Right from the aggregate Fair Market Value (as
              determined below) for the Warrant shares immediately prior to the
              exercise of the Conversion Right) by (y) the Fair Market Value of
              one share of Common Stock immediately prior to the exercise of the
              Conversion Right.

          (b) The Conversion Right may be exercised by the holder, at any time
              or from time to time, prior to its expiration, on any business
              day, by delivering a written notice (the "Conversion Notice") to
              the Company at the offices of the Company 
<PAGE>
 
              exercising the Conversion Right and specifying (i) the total
              number of shares of Stock the Warrantholder will purchase pursuant
              to such conversion, and (ii) a place, and a date not less than
              five (5) nor more than twenty (20) business days from the date of
              the Conversion Notice for the closing of such purchase.

          (c) At any closing under Section 5(b) hereof, (i) the holder will
              surrender the Warrant, (ii) the Company will deliver to the holder
              a certificate or certificates for the number of shares of Common
              Stock issuable upon such conversion, together with cash, in lieu
              of any fraction of a share, and (iii) the Company will deliver to
              the holder a new Warrant representing the number of shares, if
              any, with respect to which the Warrant shall not have been
              exercised.

          (d) "Fair Market Value" of a share of Common Stock as of a particular
              date (the "Determination Date") shall mean:

              (i)  If the Company's Common Stock (or common stock) is traded on 
                   an exchange or is quoted on the NASDAQ National Market System

                   sale prices, respectively, reported for the ten (10) business

              (ii) If the Company's Common Stock is not traded on an exchange 
                   or on the NASDAQ National Market System, but is traded in the

                             MEDI-JECT CORPORATION

                         COMMON STOCK PURCHASE WARRANT


     Medi-Ject Corporation, a Minnesota corporation (the "Company"), hereby
agrees that, for value received, Michael Trautner, Minneapolis, Minnesota, or
his assigns, is entitled, subject to the terms set forth below, to purchase from
the Company at any time or from time to time after March 23, 1996, and before
5:00 p.m., Minneapolis, Minnesota time, on March 24, 2000, Two Thousand (2,000)
shares of the Common Stock of the Company (the "Common Stock"), at an exercise
price of $2.50 per share, subject to adjustment as provided herein.

     1.     Exercise of Warrant.  The purchase rights granted by this Warrant 
            -------------------
shall be exercised (in minimum quantities of 1,000 shares, or such smaller
number of shares as are exercisable under the Warrant) by the holder
surrendering this Warrant with the form of exercise attached hereto duly
executed by such holder, to the Company at its principal office, accompanied by
payment, in cash or by cashier's check payable to the order of the Company, of
the purchase price payable in respect of the Common Stock being purchased. If
less than all of the Common Stock purchasable hereunder is purchased, the
Company will, upon such exercise, execute and deliver to the holder hereof a new
Warrant (dated the date hereof) evidencing the number of shares of Common Stock
not so purchased. As soon as practicable after the exercise of this Warrant and
payment of the purchase price, the company will cause to be issued in the name
of and delivered to the holder hereof, or as such holder may direct, a
certificate of certificates representing the shares purchased upon such
exercise. The Company may require that such certificate or certificates contain
on the face thereof a legend substantially as follows:

     "No sale, offer to sell or transfer of the shares represented by this
     certificate shall be made unless a Registration Statement under the Federal
     Securities Act of 1933, as amended (the "Act"), with respect to such shares
     is then in effect or an exemption from the registration requirements of the
     Act is then in fact applicable to such shares."

     2.     Negotiability and Transfer.  This Warrant is issued upon the 
            --------------------------
following terms, to which each holder hereof consents and agrees:

            (a)   Except where directed by a court of competent jurisdiction
                  pursuant to the dissolution or liquidation of a corporate
                  holder hereof, for one (1) year from March 24, 1995, title to
                  this Warrant may be transferred only to Delphi Financial Corp.
                  (the "Agent"), or to a person who is both an officer and
                  shareholder, or both an officer and employee, or a registered
                  representative, of the Agent, or to a successor (or both an
                  officer and shareholder, or both an officer and employee, or
                  both an employee and registered representative of the
                  successor) in interest to the business of the Agent, by
                  endorsement (by the holder hereof executing the form of
                  assignment attached hereto) and delivery in the same manner as
                  in the case of a negotiable instrument transferable by
                  endorsement and delivery.

            (b)   Until this Warrant is duly transferred on the books of the
                  Company, the company may treat the registered holder of this
                  Warrant as absolute owner hereof for all purposes without
                  being affected by any notice to the contrary.

            (c)   Each successive holder of this Warrant, or of any portion of
                  the rights represented thereby, shall be bound by the terms
                  and conditions set forth herein.

<PAGE>
 
      3.   Antidilution Adjustments. If the Company shall at any time hereafter 
           ------------------------
subdivide or combine its outstanding shares of Common Stock, or declare a 
dividend payable in Common Stock, the exercise price in effect immediately 
prior to the subdivision, combination or record date for such dividend payable 
in Common Stock shall forthwith be proportionately increased, in the case of 
combination, or proportionately decreased, in the case of subdivision or 
declaration of a dividend payable in Common Stock, and each share of Common 
Stock purchasable upon exercise of this Warrant, immediately preceding such 
event, shall be changed to the number determined by dividing the then current 
exercise price by the exercise price as adjusted after such subdivision, 
combination or dividend payable in Common Stock.

      No fractional shares of Common Stock are to be issued upon the exercise of
the Warrant, but the Company shall pay a cash adjustment in respect of any 
fraction of a share which would otherwise be issuable in an amount equal to the 
same fraction of the market price per share of Common Stock on the day of 
exercise as determined in good faith by the Company.

      In case of any capital reorganization or any reclassification of the 
shares of Common Stock of the Company, or in the case of any consolidation with 
or merger of the Company into or with another corporation, or the sale of all or
substantially all of its assets to another corporation, which is effected in 
such manner that the holders of Common Stock shall be entitled to receive stock,
securities or assets with respect to or in exchange for Common Stock, then, as a
part of such reorganization, reclassification, consolidation, merger or sale, as
the case may be, lawful provision shall be made so that the holder of the 
Warrant shall have the right thereafter to receive, upon the exercise hereof, 
the kind and amount of shares of stock or other securities or property which the
holder would have been entitled to receive if, immediately prior to such 
reorganization, reclassification, consolidation, merger or sale, the holder had 
held the number of shares of Common Stock which were then purchasable upon the 
exercise of the Warrant. In any such case, appropriate adjustment (as determined
in good faith by the Board of Directors of the Company) shall be made in the 
application of the provisions set forth herein with respect to the rights and 
interest thereafter of the holder of the Warrant, to the end that the provisions
set forth herein (including provisions with respect to adjustments of the 
exercise price) shall thereafter be applicable, as nearly as reasonably may be, 
in relation to any shares of stock or other property thereafter deliverable upon
the exercise of the Warrant.

      When any adjustment is required to be made in the exercise price, initial 
or adjusted, the Company shall forthwith determine the new exercise price, and

      (a)   prepare and retain on file a statement describing in reasonable 
            detail the method used in arriving at the new exercise price; and

      (b)   cause a copy of such statement to be mailed to the holder of the
            Warrant as of a date within ten (10) days after the date when the
            circumstances giving rise to the adjustment occurred.

      4.    Registration Rights. Prior to making any disposition of the Warrant 
            -------------------
or of any Common Stock purchased upon exercise of the Warrant, the holder will 
give written notice to the Company describing briefly the manner of any such 
proposed disposition. The holder will not make any such disposition until (i) if
requested, the Company has been provided an opinion by counsel for the holder 
that registration under the Act is not required with respect to such 
disposition, or (ii) a Registration Statement covering the proposed distribution
has been filed and has become effective. The holder then will make any 
disposition only pursuant to the conditions of such opinion or registration. The
Company agrees that, upon receipt of written notice from the holder hereof with 
respect to such proposed distribution, it will cooperate in providing the holder
with information necessary to make such determination.

      If, at any time prior to the expiration of seven (7) years from March 24, 
1995, the Company shall propose to file any Registration Statement (other than 
any registration on Forms S-4, S-8 or any
<PAGE>
 
other similarly inappropriate form or Registration Statement with respect to an
initial public offering in which there are no selling shareholders) under the
Securities Act of 1933, as amended, covering a public offering of the Company's
Common Stock, it will notify the holder hereof at least forty-five (45) days
prior to each such filing and will include in the Registration Statement (to the
extent permitted by applicable regulation) the Common Stock purchased by the
holder or purchasable by the holder upon the exercise of the Warrant to the
extent requested by the holder hereof, in writing, within twenty (20) days of
the holder's receipt of such notice from the Company. Notwithstanding the
foregoing, the number of shares of the holders of the Warrants proposed to be
registered thereby shall be reduced pro rata with any other selling shareholder
(other than the Company) upon the request of the managing underwriter of such
offering. If the Registration Statement or Offering Statement filed pursuant to
such forty-five (45) day notice has not become effective within six months
following the date such notice is given to the holder hereof, the Company must
again notify such holder in the manner provided above.

     All expenses of any such registrations referred to in this Section 4,
except the fees of counsel to such holders and underwriting commissions or
discounts, filing fees, and any transfer or other taxes applicable to such
shares, shall be borne by the Company.

     The Company will furnish the holder hereof with a reasonable number of
copies of any prospectus included in such filings and will amend or supplement
the same as required during the period of required use thereof.

     In the case of the filing of any Registration Statement, and to the extent
permissible under the Securities Act of 1933, as amended, and controlling
precedent thereunder, the Company and the holder hereof shall provide cross
indemnification agreements to each other in customary scope covering the
accuracy and completeness of the information furnished by each.

     The holder of the Warrant agrees to cooperate with the Company in the
preparation and filing of any such Registration Statement or Offering Statement,
and in the furnishing of information concerning the holder for inclusion
therein, or in any efforts by the Company to establish that the proposed sale is
exempt under the Act as to any proposed distribution.

     5.   Right to Convert.
          ----------------
            
     (a)  If the Company's Common Stock is traded on an exchange or is quoted on
          the National Association of Securities Dealers, Inc. ("NASDAQ")
          Automated Quotation National Market System or Small-Cap System or is
          traded in the over-the-counter market, then the holder of this Warrant
          shall have the right to require the Company to convert this Warrant
          (the "Conversion Right"), at any time prior to its expiration, into
          shares of Common Stock as provided for in this Section 5. Upon
          exercise of the Conversion Right, the Company shall deliver to the
          holder (without payment by the holder of any exercise price) that
          number of shares of Common Stock equal to the quotient obtained by
          dividing (x) the value of the Warrant at the time the Conversion Right
          is exercised (determined by subtracting the aggregate exercise price
          for the Warrant Common Stock in effect immediately prior to the
          exercise of the Conversion Right from the aggregate Fair Market Value
          (as determined below) for the Warrant shares immediately prior to the
          exercise of the Conversion Right) by (y) the Fair Market Value of one
          share of Common Stock immediately prior to the exercise of the
          Conversion Right.

     (b)  The Conversion Right may be exercised by the holder, at any time or
          from time to time, prior to its expiration, on any business day, by
          delivering a written notice (the "Conversion Notice") to the Company
          at the offices of the Company 
<PAGE>
 
          exercising the Conversion Right and specifying (i) the total number of
          shares of Stock the Warrantholder will purchase pursuant to such
          conversion, and (ii) a place, and a date not less than five (5) nor
          more than twenty (20) business days from the date of the Conversion
          Notice for the closing of such purchase.

     (c)  At any closing under Section 5(b) hereof, (i) the holder will
          surrender the Warrant, (ii) the Company will deliver to the holder a
          certificate or certificates for the number of shares of Common Stock
          issuable upon such conversion, together with cash, in lieu of any
          fraction of a share, and (iii) the Company will deliver to the holder
          a new Warrant representing the number of shares, if any, with respect
          to which the Warrant shall not have been exercised.

     (d)  "Fair Market Value" of a share of Common Stock as of a particular date
          (the "Determination Date") shall mean:
          
          (i)  If the Company's Common Stock (or common stock) is traded on an
               exchange or is quoted on the NASDAQ National Market System or the
               Small-Cap System, then the average closing or last sale prices,
               respectively, reported for the ten (10) business days immediately
               preceding the Determination Date.

          (ii) If the Company's Common Stock is not traded on an exchange or on
               the NASDAQ National Market System, but is traded in the over-the-
               counter market, then the average of the closing bid and asked
               prices reported for the ten (10) business days immediately
               preceding the Determination Date.


     6.   Notices. The Company shall mail to the registered holder of the
          -------     
Warrant, at the holder's last known post office address appearing on the books
of the Company, not less than fifteen (l5) days prior to the date on which (a) a
record will be taken for the purpose of determining the holders of Common Stock
entitled to dividends (other than cash dividends) or subscription rights, or (b)
a record will be taken (or in lieu thereof, the transfer books will be closed)
for the purpose of determining the holders of Common Stock entitled to notice of
and to vote at a meeting of stockholders at which any capital reorganization,
reclassification of shares of Common Stock, consolidation, merger, dissolution,
liquidation, winding up or sale of substantially all of the Company's assets
shall be considered and acted upon.

     7.   Reservation of Common Stock. A number of shares of Common Stock
          ---------------------------
sufficient to provide for the exercise of the Warrant upon the basis herein set
forth shall at all times be reserved for the exercise thereof.

     8.   Miscellaneous. The Company will not, by amendment of its Articles of
          ------------- 
Incorporation or through reorganization, consolidation, merger, dissolution or
sale of assets, or by any other voluntary act or deed, avoid or seek to avoid
the observance or performance of any of the covenants, stipulations or
conditions to be observed or performed hereunder by the Company, but will, at
all times in good faith, assist, insofar as it is able, in the carrying out of
all provisions hereof and in the taking of all other action which may be
necessary in order to protect the rights of the holder hereof against dilution.

     The representations, warranties and agreements herein contained shall
survive the exercise of this Warrant. References to the "holder of" include the
immediate holder of shares purchased on the exercise of this Warrant, and the
word "holder" shall include the plural thereof. This Common Stock Purchase
Warrant shall be interpreted under the laws of the State of Minnesota.
<PAGE>
 
     All shares of Common Stock or other securities issued upon the exercise of
the Warrant shall be validly issued, fully paid and non-assessable, and the
Company will pay all taxes in respect of the issuer thereof.

     Notwithstanding anything contained herein to the contrary, the holder of
this Warrant shall not be deemed a stockholder of the Company for any purpose
whatsoever until and unless this Warrant is duly exercised.

     IN WITNESS WHEREOF, this Warrant has been duly executed by Medi-Ject
Corporation, this 24th day of March, 1995.

shall be in Tenant or Landlord; (b) upon or measured by the rental payable
hereunder; (c) upon or with respect to the possession, leasing, operation,
management, maintenance, improvement, alteration, repair, use or occupancy by
Tenant of the premises or portion thereof; (d) upon this transaction or any
document to which Tenant is a party creating or transferring an interest or an
estate in the premises.

6.    Operating Expenses.  Tenant shall, during the entire term hereof, pay to
Landlord tenant's percentage share of the amount by which all Operating Expenses
paid or incurred by Landlord in any Lease Year exceed Base Operating Expenses.

7.    Estimated Payments.  Unless otherwise expressly designated herein, all
monetary amounts payable by Tenant to Landlord pursuant to this Lease shall be
payable as follows:

      (a)   During December of each Lease Year or as soon thereafter as
practicable, Landlord shall give Tenant Notice of its estimate of amounts
payable hereunder for the ensuing Lease Year.  On or before the first day of
each month during the ensuing Lease Year, Tenant shall pay to Landlord 1/12 of
such estimated amounts, provided that if such notice is not given in December,
Tenant shall continue to pay on the basis of the prior year's estimate until the
month such notice is given.  If at any time or times it appears to Landlord that
the amounts payable for the current Lease Year will vary from its estimate by
more than 5%, Landlord shall, by notice to Tenant, revise its estimate for such
year, in which case subsequent payments by Tenant for such year shall be based
upon such revised estimate.

      (b)   Within 90 days after the close of each Lease Year or as soon after
such 90-day period as practicable, Landlord shall deliver to Tenant a statement
of amounts payable for such Lease Year. Tenant shall have the right, at Tenant's
expense, to inspect or audit Landlord's document records or other information
used to determined such statement. If on the basis of such statement Tenant owes

<PAGE>
 
amount that is less than the estimated payments for such Lease Year previously
made by Tenant and tenant is not in default hereunder, Tenant shall receive a
credit in the amount of such excess against the next installments due under
paragraphs 6 and 7 hereof. If on the basis of such statement Tenant owes an
amount that is more than the estimated payments for such Lease Year previously
made by Tenant, Tenant shall pay the deficiency to Landlord within thirty (30)
days after delivery of the statement.

      (c)   If this lease shall terminate on other than the last day of a
calendar year, the adjustment in rent applicable to the Lease Year in which such
termination shall occur shall be prorated on the basis which the number of days

portion of the common area which is reasonably and customarily used by Tenant's
customers.

            (2)   Landlord shall have the right to establish and from time to
time change, alter, amend and to enforce against Tenant and other users of the
common areas, such reasonable rules and regulations as may be deemed necessary

            (3)   Landlord shall have the sole and exclusive control of the
common area, and may at any time and from time to time exclude and restrain any

dedication or other prescriptive right therein in favor of the public or any
group or individual and to prevent the accrual of any such right, and Landlord
shall have the right by temporary closure or other reasonable means to
discourage or prevent the use of the common area by persons other than those
expressly authorized hereby.

9.    Use.

      (a)   The premises shall be used solely for the permitted use as described
in the Basic Lease information and for any other lawful purpose not otherwise
violating any zoning ordinance or regulation with Landlord's consent. Tenant
shall not use or permit the premises to be used for any other purpose without
Landlord's prior written consent. Landlord and tenant hereby further acknowledge
that the identity of Tenant, the specific character of Tenant's business and
anticipated use of the premises and the relationship between the use and other
uses within the Building has been a material consideration to Landlord's entry
into this Lease. Any material change in the character of Tenant's business or
use may constitute a default use this Lease.

      (b)   Tenant shall not do or permit to be done in, on or about the
premises, nor bring or keep or permit to be brought or kept therein, anything
which is prohibited by or will in any way conflict with any law, statute,
ordinance or governmental rule or regulation now in force or which may hereafter
be enacted or promulgated, or which is prohibited by the standard form of fire
insurance policy or will in any way increase the existing rate of or affect any
fire or other insurance upon the Building, or cause a cancellation of any
insurance policy covering the building or any part thereof of any of its
contents. Tenant shall not do or permit anything to be done in or about the
premises which will in any way obstruct or interfere with the rights of other
tenants of the Building or injure or annoy them, or use or allow the premises to
be used for any improper, immoral, unlawful or objectionable purpose. Nor shall
Tenant cause, maintain or permit any nuisance in, or about or commit or suffer
to be committed any waste in or upon the premises.

      (c)   Tenant shall not cause or permit any Hazardous Material to be
brought upon, kept or used in or about the premises or the Building. If Tenant
breaches the obligations stated in the preceding sentence, or if the presence of
Hazardous Material on the premises or the Building caused or permitted by Tenant
results in contamination of the premises or the Building then Tenant shall
indemnify, defend and hold Landlord harmless for, from and against any and all
claims, judgments, damages, penalties, fines, costs, liabilities or losses
(including without limitation, diminution in value of the Building, damages for
the loss or restriction on use of rentable or usable space or any amenity of the
Building, damages arising from any adverse impact on marketing of space in the
Building, and sums paid in settlement of claims, reasonable attorneys' fees,
consultant fees and expert fees) which arise during or after the Lease Term as a
result of such contamination. This indemnification of Landlord by Tenant
includes, without limitation, costs incurred in connection with any
investigation of site conditions or any cleanup, remedial, removal or
restoration work required by any federal, state or local government agency or
political subdivision because of Hazardous Material present in or about any part
of the Building including, without limitation, the soil or ground water under
the Building.

      As used herein, the term "Hazardous Material" means any hazardous or toxic
substance, material or waste which is or becomes regulated by any federal, state
or other local governmental authority including, without limitation, any
material or substance which is designated as a "hazardous substance" pursuant to
Section 311 of the Federal Water Pollution Control Act (33 U.S.C. (S) 1317),
defined as a "hazardous waste" pursuant to Section 1004 of the Federal Resource
Conservation and Recovery Act, (42 U.S.C. 6901 et seq.). or defined as a
"hazardous waste" pursuant to Section 101 of the Comprehensive Environmental
Response, Compensation and Liability Act, (42 U.S.C. (S) 9601 et seq).

10.   Utilities.  Tenant shall pay all initial utility deposits and fees, and
all monthly service charges for water, electricity, sewage, gas, telephone and
any other utility services furnished to the premises and the improvements
thereon during the entire term of this Lease. In the event any such services are
not separately metered or billed to Tenant but rather are billed to and paid by
Landlord, Tenant shall pay to Landlord its pro rata share of the cost of such
services, as determined on the Basic Lease Information. Landlord shall not be
liable for any reason for any loss or damage resulting from an interruption of
any of the above services, provided that, such interruption is not the result of
Landlord's, its agents' or employees' negligence.

11.   Alteration, Fixtures and Improvements.

      (a)   Tenant shall not make or suffer to be made any alterations,
additions, or improvements to or of the premises or any part thereof, or attach
any fixture or equipment thereto, without first obtaining Landlord's written
consent. Any alterations, additions or improvements to the premises consented to
by Landlord shall be made by Tenant at Tenant's sole cost and expense according
to plans and specifications approved by Landlord, and any contractor or person
selected by Tenant to make the same must first be approved by Landlord. Landlord
may require, at its option, that Tenant provide Landlord at Tenant's sole cost
and expense, payment and performance bonds in an amount equal to the estimated
cost of any contemplated alterations, fixtures, and improvements, to insure
Landlord against any liability for mechanic's or materialmen's liens and to
insure the completion of such work. All


                                      -5-
<PAGE>
 
alterations, additions, fixtures and improvements, whether temporary or
permanent in character, made in or upon the premises either by Landlord (other
than furnishings, trade fixtures and equipment installed by Tenant), shall be
Landlord's property and, at the end of the term hereof, shall remain on the
premises without compensation to Tenant. Upon such removal Tenant shall
immediately and fully repair any damage to the premises occasioned by the
removal.

      (b)   Landlord may perform or cause to be performed, substantial
renovation and remodeling to the exterior and interior of the
Office/Warehouse/Showroom and Landlord reserved the right to enter the premises
in connection therewith. Landlord shall reasonably minimize any interruption of
Tenant's business caused by such renovation and remodeling. In the event such
renovation or remodeling prevents Tenant from conducts its business, Tenant's
rent shall abate for a period equal to such.

12.   Liens.   Tenant shall keep the premises and the Building free from any
liens arising out of any work performed, material furnished or obligations
incurred by Tenant. In the event that Tenant shall not, within 10 days following
the imposition of any such lien, cause the same to be released of record,
Landlord shall have in addition to all other remedies provided herein and by
law, the right but not the obligation to cause the same to be released by such
means as it shall deem proper, including payment of the claim giving rise to
such lien. All sums incurred by it in connection therewith including, without
limitation, any attorneys' fees, court costs, and expenses of litigation,
together with Default Interest thereon, shall be payable to Landlord by Tenant
on demand. Nothing in this Lease shall be construed in any way as constituting
the consent or request of the Landlord, expressed or imposed, by inference or
otherwise to any contractor, subcontractor, laborer, or materialmen, for the
performance of any labor, or the furnishing of any material for any specific
improvement, alteration and repair of or to the premises or as giving Tenant the
right, power or authority, to contract for or permit the rendering of any
service or the furnishing of any material that would give rise to the filing of
any mechanic's liens against the premises. Landlord shall have the right to post
and keep posted on the premises any notices that may be provided by law or which
Landlord may deem to be proper for the protection of Landlord, the premises and
the Building from such liens, and Tenant shall give Landlord at least 5 days'
prior notice of the date of commencement of any construction on the premises in
order to permit the posting of such notices. Notwithstanding the foregoing,
Tenant shall have the right to contest any mechanic's lien by posting security
in the amount of such dispute.

13.   Repairs and Maintenance.

      (a)   Tenant shall at all times during the term of this Lease keep and
maintain at its own cost and expense, in good order, condition and repair the
entire premises (including, without limitation, all improvements, fixtures and
equipment thereon) making all repairs* and replacements interior and exterior,
above or below ground, and ordinary or extraordinary; provided, however, that if
the premises are only a portion of a building which contains other leasable
space, then Landlord shall keep in good order, condition and repair the
foundations and exterior walls (excluding the interior of all walls and the
exterior and interior of all doors, plate glass, display and other windows, and
excluding interior ceiling) of the premises, except for any damage thereto
caused by and any act, negligence or omission of Tenant or Tenant's employees,
agents, contractors or customers, except for reasonable wear and tear and except
for any structural alterations or improvements required by any governmental
agency by reason of Tenant's use and occupancy of the premises.  Tenant shall
reimburse Landlord for Tenant's pro rata share of the costs which Landlord
incurs in performing its foregoing repair and maintenance obligations with
respect to all of the building within the Office/Warehouse/ Showroom which
Landlord is obligated to repair and maintain.  Tenant's pro rata share shall be
in the same proportion as defined in the Basic Lease.

      *     Any replacements of HVAC and underground plumbing required by this
paragraph shall be made by Landlord, and Landlord shall amortize such cost over
the useful life of this replacement, and Tenant shall pay its share of such
amortized expense incurred during the remaining Term, as additional rent as
defined by paragraph 4 of this Lease.

Reimbursement by Tenant to Landlord for its share of such costs shall be made in
the manner set forth in paragraph 8 hereof.  It is an express condition
precedent to all obligations of Landlord to repair that Tenant shall have
notified Landlord in writing of the need for such repair.  If Landlord shall
fail to commence the making of repairs as it is obligated to do by the terms
hereof within thirty (30) days after such notice and the failure to repair has
materially interfered with Tenant's use of the premises, Tenant's sole right and
remedy for such failure on the part of the Landlord shall be to cause such
repairs to be made and to charge Landlord the reasonable cost therefor; provided
that, if the repair to be performed by Landlord is of an emergency type and if
Landlord after receiving notice from Tenant of such emergency fails to commence
repair of same as soon as reasonably possibly, Tenant may do at Landlord's cost,
without waiting thirty (30) days.

      (b)   Tenant's obligation to keep and maintain the premises in good order,
condition and repair shall include, without limiting the generality of Tenant's
obligations, all plumbing and sewage facilities in the premises, floors
(including floor coverings), doors, locks and closing devices, window


                                      -6-
<PAGE>
 
casements and frames, glass and plate glass, grilles, all electrical facilities
and equipment, HVAC system and equipment, all other appliances and equipment f
every kind and nature, and all landscaping upon, within or attached to the
premises provided that any replacement to any of the foregoing shall be made
pursuant to Section (a) of this paragraph. In addition, Tenant shall at its sole
cost and expense install or construct any improvements, equipment, or fixtures
required by any governmental authority or agency as a consequence of Tenant's
use and occupancy of the premises. Tenant shall replace any damaged plate glass
within forty-eight (48) hours of the occurrence of such damage.

      (c)   Landlord shall assign to Tenant, and Tenant shall have the benefit
of, any guarantee or warranty to which Landlord is entitled under any purchase,
construction or installation contract relating to a component of the premises
which Tenant is obligated to repair and maintain. Tenant shall have the right to
call upon the contractor to make such adjustments, replacements, or repairs
which are required to be made by the contractor under such contract.

      (d)   Landlord may at Landlord's option employ and pay a firm satisfactory
to Landlord, engaged in the business of maintaining systems, to perform periodic
inspections of the HVAC systems serving the premises and to perform any
necessary work, maintenance or repair thereon, provided and said rates are
competitive. In such event, Tenant shall reimburse Landlord for all sums paid by
Landlord in connection therewith, such reimbursement to be made in the manner
set forth in paragraph 8 above.

      (e)   Upon the expiration or termination of this Lease, Tenant shall
surrender the premises to Landlord in good order, condition and state of repair,
ordinary wear and tear excepted.  Tenant hereby waives the right to make repairs
at Landlord's expense under the provisions of any laws permitting repairs by a
tenant at the expense of a landlord to the extent allowed by law; Landlord and
Tenant have by this Lease made specific provision for such repairs and have
expressly defined their respective obligations.

14.   Damage and Destruction.

      (a)   If the premises or the portion of the Office/Warehouse/Showroom
necessary for Tenant's occupancy should be damaged or destroyed during the term
hereof by any casually insurable under standard fire and extended coverage
insurance policies, Landlord shall (except as hereafter provided) repair or
rebuild the premises to substantially the condition in which the premises were
immediately prior to such destruction.

      (b)   Landlord's obligation under this paragraph shall in no event exceed
the extent of proceeds received by Landlord of any insurance policy maintained
by Landlord pursuant to paragraph 16(b) below, unless Landlord nevertheless
elects to repair or rebuild the premises.

      (c)   The minimum rent shall be abated proportionately during any period
in which there is a substantial interference with the operation of the business
of Tenant. Such abatement shall be proportional to the amount that the net
rentable area damaged bears to the total net rentable area. In the event that
Tenant is unable to operate its business as a result of such damage, Rent as
defined paragraph 4 shall abate in its entirety in the premises which Tenant may
be required to discontinue. The abatement shall continue for the period
commencing with such destruction or damage and ending with the completion by the
Landlord of such work, repair or reconstruction as Landlord is obligated to do.

      (d)   Notwithstanding the foregoing, if the premises, or, the portion of
the Office/Warehouse/Showroom necessary for Tenant's occupancy should be damaged
or destroyed (1) to the extent of 10% or more of the then replacement value of
either, (2) in the last year of the term hereof, (3) by a cause or casually
other than those covered by fire and extended coverage insurance, or (4) to the
extent that it would take, in Landlord's opinion, in excess of ninety (90) days
to complete the requisite repairs, then Landlord may either terminate this Lease
or elect to repair or restore said damage or destruction, in which event
Landlord shall repair or rebuild the same as provided in subparagraph (a) above.
If such damage or destruction occurs and this Lease is not so terminated by
Landlord, this Lease shall remain in full force and effect. The parties hereby
waive the provisions of any law that would dictate automatic termination or
grant either party an option to terminate in the event of damage or destruction.
Landlord's election to terminate the Landlord's obligation under this paragraph
shall be exercised by written notice to Tenant given within sixty (60) days
following the damage or destruction. Such notice shall set forth the effective
date of the termination of this Lease. Notwithstanding the foregoing, in the
event Landlord elects to repair the Premises and such repair is not completed
within 90 days of such casualty, Tenant shall have the right to terminate this
Lease.

      (e)   Upon the completion of any such work of repair or restoration by
Landlord, Tenant shall forthwith repair and restore all other parts of the
premises including without limitation, non-building standard leasehold
improvements and all trade fixtures, equipment, furnishings, signs and other
improvements originally installed by Tenant, subject to the requirements of
paragraph 11(a) above.


                                      -7-
<PAGE>
 
      (f)   Tenant agrees during any period of reconstruction or repair of the
premises to continue the operation of its business in the leased premises to the
extent reasonably practicable from the standpoint of good business.

15.   Indemnification.   Landlord shall not be liable to Tenant and Tenant
hereby waives all claims against Landlord for any injury to or death of any
person or damage to or destruction of property in or about the premises by or
from any cause whatsoever, including, without limitation, acts of other tenants
or other third parties, gas fire, oil, electricity or leakage of any character
from the roof, walls, basement or other portion of the premises provided that
such damage is not the result of any default or omission of Landlord pursuant to
the terms and conditions of this Lease. Tenant shall hold Landlord and any
ground landlord harmless for, from and against and defend Landlord against any
and all claims, liability, damage or loss, and for, from and against all costs
and expenses, including reasonable attorneys' fees, arising out of any injury to
or death of any person or damage to or destruction of any property, from any
cause whatsoever (except any cause resulting solely from the negligence or
willful act of Landlord, its authorized agents or employees) occurring in or
about the premises and, if occurring on or about any portion of the common areas
or elsewhere in or about the Building, when such injury or damage shall be
caused in whole or in part by the act, neglect, default or omission of any duty
by Tenant, its agents, employees or invitees, including any failure of Tenant to
observe or perform any of its obligations hereunder. The provisions of this
paragraph 15 shall survive the termination of this Lease with respect to any
damage, injury or death occurring prior to such termination. See Addendum.

16.   Insurance.

      (a)   Tenant shall procure and maintain in full force and effect during
the entire term hereof, at its own expense and in companies acceptable to
Landlord, the following policies of insurance:

            (1)   Comprehensive liability insurance, including property damage,
insuring Landlord and Tenant from and against all claims, demands, actions or
liability for injury to or death of any persons, and for damage to property
arising from or related to the use of occupancy of the premises or the operation
of Tenant's business.  No reasonable deductible shall be carried under this
coverage without the prior written consent of Landlord.  Such policy shall
contain, but not be limited to, coverage for premises and operations, products
and completed operations, blanket contractual, personal injury, operations,
ownership, maintenance and use of owned, non-owned, or hired automobiles, bodily
injury and property damage.  The policy shall have limits in amounts not less
than one million dollars ($1,000,000.00) per person and per occurrence.  This
insurance shall carry a contractual coverage endorsement specifically insuring
the performance by Tenant of its indemnity agreement contained in paragraph 15
above.  If in the opinion of Tenant's insurance advisor, based on a substantial
increase in recovered liability claims, the aforesaid amounts of coverage are no
longer adequate, then such work shall be proportionately increased.

            (2)   Worker's Compensation Insurance and Employer's Liability
Insurance per State guidelines.

            (3)   Fire Insurance with standard extended coverage of "all risk"
endorsement including, without limitation, vandalism and malicious mischief, to
the extent of 90% of the replacement value of all furnishings trade fixtures,
leasehold improvements, equipment, merchandise and other personal property and
leasehold improvements from time to time situated in, on or upon the premises.
As long as this Lease is in effect, the proceeds rom any such insurance shall be
held in trust to be used only for the repair or replacement of the improvements,
fixtures and other property so insured.

      (b)   Landlord shall procure and maintain liability insurance and all risk
insurance covering fire and such other risks of direct or indirect loss or
damage for the full insurable value of the Building, including extended and
broad form coverage risks, mudslide, land subsidence, volcanic eruption, flood
and earthquake, on leasehold improvements in the Building.  Tenant shall
reimburse Landlord for the costs of all such insurance as part of Operating
Expenses reimbursable pursuant to paragraph (6).  Any insurance coverage herein
provided shall be for the benefit of Landlord, Tenant and any additional
designated insured, as their interests may appear.  Tenant shall not adjust
losses or execute proofs of loss under such policies without Landlord's prior
written approval.

      (c)   Should this Lease be canceled pursuant to the provisions of
paragraph 14 above by reason of damage or destruction and Tenant is thus
relieved of its obligation to restore or rebuild the improvements on he
premises, any insurance proceeds for damage to the premises, including all
fixtures and leasehold improvements installed by Landlord thereon, shall belong
to Landlord, free and clear of any claims by Tenant.

      (d)   All policies of insurance described in this paragraph 16 of which
Tenant is to procure and maintain, shall be issued by companies, reasonably
acceptable to Landlord and qualified to do business in the state in which the
Building is situated.  Executed copies of such policies of insurance or, 


                                      -8-
<PAGE>
 
at Landlord's election, certificates thereof, shall be delivered to Landlord
within ten (10) days after delivery of possession of the premises to Tenant and
thereafter within thirty (30) days prior to the termination or expiration of the
term of each existing policy. All public liability and property damage policies
shall contain the following provisions: (1) Landlord, although named as
additional insured, shall nevertheless be entitled to recover under said
policies for any loss occasioned to them, their servants, agents and employees
by reason of the negligence of Tenant, its officers, agents or employees; (2)
the company writing such policy shall agree to give Landlord not less than
thirty (30) days' notice in writing prior to any cancellation, reduction or
modification of such insurance. All public liability, property damage and other
casualty policies shall be written as primary policies, not entitled to
contribution from, nor contributing with, any coverage which Landlord may carry.

      (e)   Notwithstanding anything to the contrary contained within this
paragraph, Tenant's obligations to carry the insurance provided for herein may
be brought within the coverage of so-called blanket policy or policies of
insurance carried and maintained by Tenant; provided, however, that (1) Landlord
and such other persons shall be named as additional insureds thereunder as their
interest may appear; (2) the coverage afforded to Landlord and such other
persons will not be reduced or diminished by reason of the use of such blanket
policy of insurance; and (3) all other requirements set forth herein are
otherwise satisfied.

      (f)   If Tenant should fall either to acquire the insurance required
pursuant to this paragraph 16 and to pay the premiums therefor or to deliver
required certificates or policies, Landlord may in addition to any other rights
and remedies available to landlord, acquire such insurance and pay the requisite
premiums therefor, which premiums shall be payable by Tenant to Landlord
immediately upon demand.

      (g)   Landlord and Tenant hereby waive any rights each may have against
the other for loss or damage to its property, or property in which it may have
an interest, where such loss is caused by a peril of the type generally covered
by fire insurance with extended coverage or arising from any cause which the
claiming party was obligated to insure against under this Lease, and each party
on behalf of its insurer waives any right of subrogation that the insurer might
otherwise have against the other party. The parties agree to cause their
respective insurance companies insuring the premises or insuring their property
on or in the premises to execute a waiver of any such rights of subrogation so
long as such a waiver does not invalidate Tenant's insurance coverage.

17.   Condemnation.

      (a)   The term "total taking" meaning the taking of the fee title or
Landlord's master leasehold estate to so much of the premises or a portion of
the Building necessary for Tenant's occupancy by right of eminent domain or
other authority of law, or a voluntary transfer under the threat of the exercise
thereof, that the premises are not suitable for Tenant's intended use.  The term
"partial taking" means the taking of only a portion of the premises or the
Building which does not constitute a total taking as above defined.

      (b)   If during the term hereof there shall be a total taking than this
Lease, and the leasehold estate of Tenant in and to the premises, shall cease
and terminate as of the date possession is taken.  As used in this paragraph the
phrase "date possession is taken" means the date of taking actual physical
possession thereof by the condemning authority or such earlier date as the
condemning authority gives notice that it shall be deemed to have taken
possession.

      (c)   If during the term hereof there shall be a partial taking of the
premises, this Lease shall terminate as of the portion of the premises taken on
the date on which actual possession of the portion of the premises is taken
pursuant to the eminent domain proceedings and this Lease shall continue in full
force and effect as the remainder of the premises.  The minimum rent payable by
Tenant for the balance of the term shall be abated in the ratio that the net
rentable area of the premises taken bears to the net rentable area of the
premises immediately prior to such taking, and Landlord shall make all necessary
repairs or alterations to make the remaining premises a complete architectural
unit.  Notwithstanding anything contained in this Section 17(c), Tenant shall
have the right to terminate the Lease in the event that either (i) such partial
taking materially interferes with the operation of Tenant's business; or (ii)
Landlord cannot make such repairs or alterations within 90 days of such taking.

      (d)   All compensation and damages award for the taking of the premises,
any portion thereof, or the whole or any portion of the common areas or Building
shall, except as otherwise herein provided belong to and be the sole property of
Landlord, and Tenant shall not have any claim or be entitled to any award for
diminution in value of its rights hereunder or for the value of any unexpired
term of this Lease; provided, however, that Tenant shall be entitled to make its
own claim for, and receive separate award that may be made for Tenant's loss of
business or for the taking of or injury to Tenant's improvements, or on account
of any cost or loss Tenant may sustain the removal of Tenant's trade fixtures,
equipment, and furnishings, or as a result of any alterations, modifications or
repairs

                                      -9-
<PAGE>
 
which may be reasonably required by Tenant in order to place the remaining
portion of the Premises not so condemned in a suitable condition for the
continuance of Tenant's occupancy. The Tenant's award pursuant to this
subparagraph shall not reduce Landlord's award.

      (e)   If this Lease is terminated pursuant to the provisions of this
paragraph 17, then all rentals and other charges payable by Tenant to Landlord
hereunder shall be paid up to the date upon which possession shall be taken by
the condemning agency and any rentals and other charges paid in advance and
allocable to the period after the date possession is taken, shall be repaid to
Tenant by Landlord, and the parties shall thereupon be released from all further
liability hereunder.

18.   Compliance With Legal Requirements.  Tenant shall at its sole cost and
expense promptly comply with all laws, statutes, ordinances and governmental
rules, regulations or requirements now in force or which may hereafter be in
force, with the requirements of any board of fire underwriters or other similar
body now or hereafter constituted, with any direction or occupancy certificate
issued pursuant to any law by any public officer or officers, as well as the
provisions of all recorded documents affecting the premises, as they relate to
or affect the condition, use or occupancy of the premises, excluding
requirements of structural changes not related to or affected by improvements
made by or for Tenant or Tenant's use of the premises.  Landlord warrants that
the Premises comply with all applicable governmental rules, regulations and
other requirements of this paragraph not otherwise a result of Tenant's use of
the premises.

19.   Assignment and Subletting.

      (a)   Tenant shall not transfer, assign, sublet, enter into license or
concession agreements, or hypothecate this Lease or the Tenant's interest in and
to the premises without first procuring the written consent of Landlord, which
consent shall not unreasonably be withheld.  Any attempted transfer, assignment,
subletting license or concession agreement or hypothecation without Landlord's
consent shall be void and shall, at the option of Landlord, terminate this
Lease.  This Lease shall not, nor shall any interest herein, be assignable as to
the interest of Tenant by operation of law without the consent of Landlord.
Tenant agrees to reimburse Landlord for Landlord's reasonable attorneys' fees
incurred in conjunction with the processing and documentation of any such
requested transfer, assignment, subletting, licensing or concession agreement,
or hypothecation of this Lease or Tenant's interest in and to the premises.

      (b)   Before entering into any assignment of this Lease or into a sublease
of all or part of the premises, Tenant shall give written notice to Landlord
identifying the intended assignee or subtenant by name and address and
specifying the terms of the intended assignment or sublease. For a period of ten
(10) business days, after such notice is given, Landlord shall have the right by
written notice to Tenant to (i) in the case of a proposed sublease either (A)
sublet from Tenant any portion of the premises proposed to be sublet for the
term for which such portion is proposed to be sublet but at the same rent as
Tenant is required to pay Landlord under this Lease for the same space, computed
on a pro rata square footage basis, or (B) if the proposed subletting is for
substantially the remaining period of the term of this Lease, terminate this
Lease, or terminate this Lease as it pertains to me portion of the premises so
proposed by Tenant to be sublet, or (ii) in the case of a proposed assignment,
terminate this Lease. If Landlord so terminates this Lease, such termination
shall be as of the date specified in Landlord's notice. If Landlord so
terminates this Lease, Landlord may, if it elects enter into a new lease
covering the premises or a portion thereof with the intended assignee or
subtenant on such terms as Landlord and such person may agree, or enter into a
new lease covering the premises or a portion thereof with any other person; in
such event, Tenant shall not be entitled to any portion of the profit, if any,
which Landlord may realize on account of such termination and reletting.
Landlord's exercise of its aforesaid option shall not be construed to impose any
liability upon Landlord with respect to any real estate brokerage commission(s)
or any other costs or expenses incurred by Tenant in connection with its
proposed subletting or assignment.

      (c)   If Tenant complies with the provisions of this section and Landlord
does not exercise an option provided to Landlord under (b) above, Landlord's
consent to a proposed assignment or sublet shall not be unreasonably withheld.
Without limiting the other instances in which it may be reasonable for Landlord
to withhold his consent to an assignment or subletting, Landlord and Tenant
acknowledge that it shall be reasonable for Landlord to withhold its consent in
any of the following instances:

            (1)   the proposed assignee or sublessee is a governmental agency;

            (2)   In Landlord's reasonable judgment, the use of the premises by
the proposed assignee or sublessee would entail any alterations which would
lessen the value of the leasehold improvements in the premises, or would require
increased services by Landlord;

            (3)   In Landlord's reasonable judgment, the financial worth of the
proposed assignee or sublessee does not meet the credit standards applied by
Landlord for other tenants under leases with comparable terms;


                                     -10-
<PAGE>
 
            (4)   In Landlord's reasonable judgment, the character, reputation
or business of tenant is inconsistent with the desired tenant-mix or the quality
of other tenancies in the Building;

            (5)   Landlord has received from any prior lessor to the proposed
assignee or subtenant a negative report concerning such prior lessor's
experience with the proposed assignee or subtenant;

            (6)   Landlord has experienced previous defaults by or is in
litigation with the proposed assignee or subtenant;

            (7)   (i) the proposed assignee's or subtenant's anticipated use of
the premises involves the generation, storage, use, treatment or disposal of
Hazardous Material; (ii) the proposed assignee or subtenant has been required by
any prior landlord, lender or governmental authority to take remedial action in
connection with Hazardous Material contaminating a property if the contamination
resulted from such assignee's or subtenant's actions or use of the property in
question; or (iii) the proposed assignee or subtenant is subject to an
enforcement order issued by any governmental authority in connection with the
use, disposal or storage of a Hazardous Material;

            (8)   the use of the premises by the proposed assignee or subtenant
will violate any applicable law, ordinance or regulation;

            (9)   the proposed assignment or sublease will create a vacancy
elsewhere in the Building;

            (10)  the proposed assignee or subtenant is a person with whom
Landlord is negotiating to lease space in the Building.

            (11)  the proposed assignment or sublease fails to include all of
the terms and provisions required to be included therein pursuant to this
paragraph;

            (12)  Tenant is in default of any obligation of Tenant under this

during the twelve (12) months preceding the date that Tenant shall request
consent; or

            (13)  In the case of a subletting of less than the entire premises,
if the subletting would result in the division of the premises into more than
two subparcels or would require access to be provided through space leased or
held for lease to another tenant or improvements to be made outside of the
premises.

      (d)   In the case of an assignment, 100% of any sums or other economic
consideration received by Tenant as a result of such assignment shall be paid to
Landlord after first deducting the unamortized cost of leasehold improvements
paid by Tenant, and the cost of any real estate commissions incurred in
connection with such assignment.  In the case of a subletting, 100% of any sum
or economic consideration received by Tenant as a result of such subletting
shall be paid to Landlord after first deducting (1) the rental due hereunder,
prorated to reflect only rental allocable to the sublet portion of the premises,
and (2) the cost of any real estate commissions incurred in connection with such
subletting, amortized over the term of the sublease.  Upon Landlord's request,
Tenant shall assign to Landlord all amounts to be paid to Tenant by any such

      (e)   Notwithstanding the provisions of subparagraphs (a) and (b) above,

full, the obligations of Tenant under this Lease.

      (f)   Regardless of Landlord's consent, no subletting, assignment,
hypothecation, license or concession shall release Tenant of Tenant's obligation
or alter the primary liability of Tenant to pay the rental and to perform all

by Landlord from any other person shall not be deemed to be a waiver by Landlord
of any provision hereof.  Consent to one assignment, subletting, hypothecation,
license or concession agreement shall not be deemed consent to any subsequent
assignment, subletting, hypothecation, license or concession agreement.  In the
event of default by any assignee of Tenant or any successor of Tenant in the
performance of any of the terms hereof, Landlord may proceed directly against
Tenant without the necessity of exhausting remedies against such assignee or
successors.  Landlord may consent to subsequent assignments, subletting,
hypothecations, licenses or concession agreements and to amendments or
modifications to this Lease, with assignees of Tenant without notifying Tenant
or any successor of 


                                     -11-

sublessor, licensor, concessionaire, hypothecator or mortgagee in each instance,
as the case may be; and each transferee, assignee or sublessee shall agree in
writing for the benefit of Landlord to assume, to be bound by, and to perform
the terms, covenants and conditions of this Lease to be done, kept and performed
by Tenant.  One executed copy of such instrument shall be delivered to Landlord.
No sublessee other than Landlord shall have the right further to sublet.

      (h)   In the event Tenant shall assign or sublet the premises or request
Landlord's consent to a proposed assignment, subletting, or other act, then
Tenant shall pay Landlord's reasonable attorneys' fees incurred in connection
therewith.

20.   Rules and Regulations.   Tenant shall faithfully observe and comply with
the rules and regulations attached to this Lease as Exhibit C and, after notice
thereof, all reasonable modifications thereof and additions thereto from time to
time promulgated in writing by Landlord. Landlord shall not be responsible to

all such work shall be done as promptly as reasonably possible and so as to
cause as little interference to Tenant as reasonably possible and that any
repairs, alterations, or additions to the premises shall, when completed, not
materially and adversely affect Tenant's use of the premises.  Tenant's Rent, as
defined by paragraph 4 hereof, shall abate for the period of time that any such
action by Landlord materially interferes with Tenant's occupancy or quiet
enjoyment of the Premises.  Landlord shall at all times have and retain a key
with which to unlock all of the doors in, on or about the premises (excluding
Tenant's vaults, safes and similar areas designated in writing by Tenant in
advance) and Landlord shall have the right to use any and all means which
Landlord may deem proper to open such doors in an emergency in order to obtain
entry to the premises.  Any entry to the premises obtained by Landlord by any of
such means, or otherwise, shall not under any circumstances be construed or
deemed to be a forcible or unlawful entry into or a detainer of the premises or
an eviction, actual or constructive, of Tenant from the premises, or any portion
thereof.

22.   Default. If: (1) Tenant shall fail to pay any rent or other sum payable
hereunder for a period of five (5) days after the same is due; (2) Tenant shall
fail to observe, keep or perform any of the other terms, covenants, agreements
or conditions contained herein or in the rules and regulations to be observed or
performed by Tenant and such default continues for a period of thirty (30) days
after notice by Landlord or beyond the time reasonably necessary for cure if
such default is of a nature to require in excess of thirty (30) days to remedy;
(3) Tenant shall become bankrupt or insolvent or make a transfer in fraud of
creditors, or make an assignment for the benefit of creditors, or take or have

a receiver is appointed for a substantial part of the assets of Tenant; (5)
Tenant shall vacate or abandon the premises; or (6) this Lease or any interest
of Tenant hereunder shall be levied upon by any attachment or execution, then

occurrence of any event of default by Tenant hereunder, Landlord may, at its
option and without any further notice or demand, in additions tony other rights
and remedies given hereunder or by law do any of the following:

      (a)   Landlord shall have the right, so long as such default continues to
give notice of termination to Tenant.  On the date specified in such notice
(which shall not be less than three (3) days after the giving of such notice)
this Lease shall terminate.

      (b)   In the event of any such termination of this Lease, Landlord may
then or at any time thereafter, re-enter the premises and remove therefrom all
persons and property and again repossess and enjoy the premises, without
prejudice to any other remedies that Landlord may have by reason of Tenant's
default or of such termination.


                                     -12-
<PAGE>
 
      (c)   The amount of damages which Landlord may recover in event of such
termination shall include, without limitation, (1) the amount at the time of
award of (A) unpaid rental earned and other sums owed by Tenant to Landlord
hereunder, as of the time of termination, together with interest thereon as
provided in this Lease, (B) the amount by which the unpaid rent which would have
been earned during the period from termination until the award exceeds the
amount of such rental loss that Tenant provides could be reasonably avoided
(computed by discounting such amount at the discount rate of the Federal REserve
Bank of San Francisco at the time of award plus one percent), (2) all legal
expenses and other related costs incurred by Landlord following Tenant's default
including reasonable attorneys' fees incurred in collecting any amount owed
hereunder, (3) all costs incurred by Landlord in restoring the premises to good
order and condition, or in remodeling, renovating or otherwise preparing the
premises for reletting, and (4) all costs (including, without limitation, any
brokerage commissions) incurred by Landlord in reletting the premises.  For the
purpose of determining the unpaid rent in the event of a termination of this
Lease, the monthly rental reserved in this Lease shall be deemed to be the sum
of (1) the minimum rent and (2) the Operating Expense charge and any other
amounts last payable by Tenant pursuant to paragraphs 5, 6, 7, 10, 13 and 16
above.

      (d)   Following the termination of this Lease or Tenant's right to
possession hereunder (or upon Tenant's failure to remove its personal property
from the premises after the expiration of the term of this Lease), Landlord may
remove any and all personal property located in the premises and place such
property in a public or private warehouse or elsewhere at the sole cost and
expense of Tenant; such warehouser shall have all rights and remedies provided
by law against Tenant as the owner of such property. In addition, in the event
that Tenant shall not immediately pay the cost of storage of such property after
the same has been stored for a period of thirty (30) days or more, Landlord may
sell any or all thereof at a public or private sale in such manner and at such
times and places as Landlord in its sole discretion may deem proper, without
notice to or demand upon Tenant. Tenant waives all claims for damages that may
be caused by Landlord's removing or storing or selling the property as herein
provided, and Tenant shall indemnify and hold Landlord free and harmless for,
from and against any and all losses, costs and damages, including without
limitation all costs of court and attorneys' fees of Landlord occasioned
thereby. Tenant hereby irrevocably appoints Landlord as Tenant's attorney-in-
fact with the rights and powers necessary in order to effectuate the provisions
of this paragraph (d). Such appointment shall be deemed coupled with an
interest.

      (e)   Landlord shall have the right to cause a receiver toe appointed in
any action against Tenant to take possession of the premises and to collect the
rents or profits derived therefrom. The appointment of such receiver shall not
constitute an election on the part of Landlord to terminate this Lease unless
notice of such intention is given to Tenant.

      (f)   Even though Tenant has breached this Lease and/or abandoned the
premises, this Lease shall continue in effect for so long as Landlord does not
terminate this Lease, the Landlord may enforce all its rights and remedies under
this Lease, including the right to recover the rental in periodic actions as it
becomes due under this Lease.  In such event, Landlord may re-enter the premises
and remove all persons and property if the premises have not been vacated, using
any available summary proceeding, without such re-entry or removal being deemed
a termination or acceptance of surrender of this Lease.  Landlord shall make
reasonable efforts to relet the premises upon commercially reasonable terms for
the account of Tenant for a period which may extend beyond the term hereof, and
upon such offer terms as Landlord may reasonably deem appropriate; provided,
however, Tenant shall be responsible for only those terms and conditions,
including Rent, for a period equal to the amount of time remaining in the Term
as defined by this Lease.  Tenant shall reimburse Landlord upon demand for all
costs incurred by Landlord in connection with such reletting, including, without
limitation, necessary restoration, renovation, or improvement costs, reasonable
attorneys' fees and brokerage commissions.  The proceeds of such reletting shall
be applied first to any sums then due and payable Landlord from Tenant,
including the reimbursement described above.  The balance, if any, shall be
applied to the payment of future rent as it becomes due hereunder.

      (g)   Landlord may change door locks if Tenant is delinquent in paying
rent, provided Landlord posts notices as required by law. If Tenant abandons the
premises, Landlord may permanently change the locks and Tenant shall not be
entitled to a key or re-entry. No other notice requirements or lockout rights
shall apply and Tenant Waiver any and all duties and/or liabilities imposed on
Landlord by Section 92.008, TX. Prop. Code.]"

23.   Landlord's Right to Cure Default.  All covenants and agreements to be
performed by Tenant under any of the terms of this Lease shall be at its sole
cost and expense and without any abatement of rental.  If Tenant shall fall to
pay any sum of money, other than rent, required to be paid by it hereunder or
shall fail to perform any other act on its part to be performed hereunder and
such failure shall have become an event of default under paragraph 22 above,
Landlord may, but shall not be obligated to do so, and without waiving or
releasing Tenant from any obligations of Tenant, making any such payment or
perform any such other act on Tenant's part to be made or performed as in this
Lease provided.  All sums so paid by Landlord and all necessary incidental costs
shall be deemed additional 


                                     -13-
<PAGE>
 
rent hereunder and shall be payable to Landlord on demand together with Default
interest from the date of expenditure by Landlord until repaid.

24.   Attorneys' Fees.  If as a result of any breach or default in the
performance of any of the provisions of this Lease or in order to enforce its
rights hereunder, Landlord or Tenant uses the services of an attorney in a
nonjudicial action, at trial, or upon an appeal, to secure compliance with such
provisions or recover damages therefor to exercise such rights, or to terminate
this Lease or evict Tenant, non-prevailing party shall reimburse the other upon
demand for any and all reasonable attorneys' fees and expenses so incurred by
such party Landlord.

25.   Subordination.

      (a)   This Lease shall be subject and subordinated at all times to all
ground or underlying leases which may hereafter by executed affecting the
Building, and the lien of all mortgages and deeds of trust in any amount or
amounts whatsoever now or hereafter placed on or against the Building or on or
against Landlord's interest or estate therein or on or against all such ground
or underlying leases, all without the necessity of having further instruments
executed on the part of Tenant to effectuate such subordination. Notwithstanding
the foregoing (1) in the event of termination for any reason whatsoever of any
ground or underlying lease hereinafter executed, this Lease shall not be barred,
terminated, cut off or foreclosed nor shall the rights and possession of Tenant
hereunder be disturbed if Tenant shall not then be in default in the payment of
rental or other sums or be otherwise in default under the terms of this Lease,

deed of trust hereafter executed or of any other action or proceeding for the
enforcement thereof, or of any sale thereunder, this Lease will not be barred,

thereunder be disturbed if Tenant shall not then be in default in e payment of
rental or other sums or be otherwise in default under the terms of this Lease,
and Tenant shall attorn to the purchaser at such foreclosure, sale or other
action or proceeding; and (3) Tenant agrees to execute and deliver upon demand
such further instruments evidencing such subordination of this Lease, ground or
underlying leases, and to the lien of any such mortgages or deeds of trust as
may reasonably be required by Landlord. Tenant's covenant to subordinate this
Lease to ground or underlying leases, and mortgages or deeds of trust hereafter
executed is conditioned upon each such senior instrument containing the
commitments specified in the preceding clauses (1) and (2).

      (b)   Tenant shall mail by certified or registered post, return receipt
requested, or personally deliver to any landlord under a ground lease or
mortgage lender a duplicate copy of any and all notices in writing which Tenant

of this Lease, and such copy shall be mailed or delivered at, or as near as
possible to, the same time such notices are given or served by Tenant.  No

and until a copy thereof shall have been so mailed or delivered to any ground

mortgage.

default which cannot with due diligence be cured with such 30-day period, the
ground lease landlord or mortgage lender shall have the additional time
reasonably necessary to accomplish the cure, provided that (i) it has commenced
the curing within such thirty (30) days and (ii) thereafter diligently
prosecutes the cure to completion.  If the default is such that the possession
of the premises may be reasonably necessary to remedy the default, any ground
lease landlord or mortgage lender shall have a reasonable additional time after
the expiration of such 30-day period within which to remedy such default,
provided that (i) it shall have fully cured any default in the payment of any
monetary obligations of Landlord under this Lease within such thirty (30) day

quiet enjoyment thereof, Tenant's Rent shall abate for a period equal to such
interference.

26.   No Merger.  The voluntary or other surrender of this Lease by Tenant, or a
mutual cancellation thereof, shall not work a merger, and shall, at the option
of Landlord, terminate all or any existing subleases or subtenancies, or may, at
the option of Landlord, operate as an assignment to it of any or all such
subleases or subtenancies.

27.   Sale by Landlord.  In the event the original Landlord hereunder, or any
successor owner of the Building shall sell or convey the Buildings, all
liabilities and obligations on the part of the original Landlord, or such
successor owner, under this Lease accruing thereafter shall terminate, and
thereupon 


                                     -14-
<PAGE>

once per year but not less than ten (10) days prior notice by Landlord, Tenant

effect (or, if there have been modifications, that this Lease is in full force
and effect, as modified, and stating the date and nature of each such
modification), (b) the date, if any, to which rental and other sums payable
hereunder have been paid, (c) that no notice has been received by Tenant of any

Landlord to be affixed to the bumpers or other designated location on all
vehicles of Tenant and its employees and agents who are authorized to park in
the parking areas.

the Basic Lease Information (the "deposit").  The deposit shall be held by
Landlord as security for the faithful performance by Tenant of all of the
provisions of this Lease to be performed or observed by Tenant.  If Tenant fails
to pay rent or other charges due hereunder, or otherwise defaults with respect
to any provision of this Lease, Landlord may use, apply or retain all or any
portion of the deposit for the payment of any rent or other charge in default or
for the payment of any other sum to which Landlord may become obligated by
reason of Tenant's default, or to compensate Landlord for any loss or damage
which Landlord may suffer thereby.  If Landlord so uses or applies all or any
portion of the deposit, Tenant shall within ten (10) days after demand therefore
deposit cash with Landlord in an amount sufficient to restore the deposit to the
full amount thereof.  Tenant's failure to do so shall be a material breach of
this Lease.  Landlord shall not be required to keep the deposit separate from
its general accounts.  If Tenant performs all of Tenant's obligations hereunder,
the deposit, or so much thereof as has not theretofore been applied by Landlord,
shall be returned, without payment of interest or other increment for its use,
to Tenant (or, at Landlord's option, to the last assignee, if any, of Tenant's
interest hereunder) at the expiration or earlier termination of the term hereof,
and after Tenant has vacated the premises; provided that Landlord may retain
such security deposit as security for the payment of any adjustment in rent
following an expiration or by reason of Tenant's default, or to compensate
Landlord for any loss or damage which Landlord may suffer thereby.  Landlord may
retain such security deposit as security for the payment of any adjustment in
rent following an expiration or termination pursuant to paragraph 7 (c) above
and shall, upon the determination of such adjustment, apply the retained
security deposit against any deficiency due Landlord and return the balance, if
any, to Tenant.  No trust relationship is created herein between Landlord and
Tenant with respect to the 


                                     -15-
<PAGE>
 
deposit. Such security deposit shall not be considered an advance payment of
rental or a measure of Landlord's damages in cash of default by Tenant.

32.   No Partnership.  It is expressly understood that Landlord does not, in any
way or for any purpose, become a partner of Tenant in the conduct of its
business, or otherwise, or joint venturer or a member of a joint enterprise with
Tenant.

33.   Recording.  Tenant shall not record this Lease without the prior written
consent of Landlord.

34.   Waiver.  The wavier by Landlord of any term, covenant, agreement or
condition hereunder contained shall not be deemed to be a waiver of any other
then existing or subsequent breach of the same or any other term, covenant,
agreement or condition herein contained.  Nor shall any custom or practice which
may develop between the parties in the administration of the terms hereof be
construed to waive or to lesson the right of the Landlord to insist upon the
performance by Tenant in strict accordance with such term.  The subsequent
acceptance of rent or any other sum of money or other performance hereunder by
Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of
any term, covenant, agreement or condition of this Lease, other than the failure
of Tenant to pay the particular rent or other sum so accepted, regardless of
Landlord's knowledge of such preceding breach at the time of acceptance of such
rent or other sum  performance.

35.   Notices and Consents.  All notices, demands, consents or approvals which
may be given by either party to the other hereunder shall be in writing and
shall be deemed to have been fully given when deposited in the United States
mail, registered or certified, return receipt requested, postage prepaid, and
addressed as follows:  to Tenant at the address specified in the Basic Lease
Information, or to such other place as Tenant may from time to time designate in
a notice to Landlord; to Landlord at the address specified in the Basic Lease

premises.  Tenant hereby appoints as its agent to receive the service of all
dispossessory or distraint proceedings and policies thereunder and person or
persons in charge of or occupying the premises at the time, and, if no person

Tenant affecting this Lease and this Lease supersedes and cancels any and all
previous negotiations, arrangements, brochures, agreements, understandings, if
any between Landlord and Tenant or displayed by Landlord to Tenant with respect
to the subject matter of this Lease or the Building.  There are no
representations between Landlord and Tenant other than those contained in this

respect whatsoever except by an instrument in writing signed by Landlord and
Tenant.

executing this Lease on behalf of the Tenant does hereby covenant and warrant
that Tenant is a duly authorized and existing corporation, that Tenant is
qualified to do business in the state in which the Building is situated, that
the corporation has full right and authority to enter into this Lease, and that
each person signing on behalf of the corporation is authorized to do so.

38.   Limits to Tenant's Remedy.  If Landlord should default in the performance
of its obligations hereunder, it is understood and agreed that any claims by
Tenant against Landlord shall be limited to recourse to Landlord's interest in

view by an y structure which may be erected on lands adjacent to or in e
vicinity of the Building shall in any way affect this Lease or impose any

of this instrument for examination or signature by Tenant does not constitute a
reservation of or option for lease, and it is not be effective as a lease or
otherwise until execution and delivery by both Landlord and Tenant.  The terms,
covenants, agreements and conditions herein contained shall, subject to the
provisions as to assignment, apply to and bind the heirs, successors, executors,
administrators and assigns of the parties hereto.  If any provisions of this
Lease shall be determined to be illegal or unenforceable, such determination
shall not affect any other provisions of this Lease and all such other


                                     -16-

other Tenant or Tenants, nor prevent Landlord from thereafter enforcing any such
Rules and Regulations against any or all of the Tenants of the Building.

17.   These Rules and Regulations are in addition to and shall note construed to
in any way modify, alter or amend, in whole or in part, the terms, covenants,
agreements and conditions of any Lease of premises in the Building.

                                   EXHIBIT D

                               ADDENDUM TO LEASE


      THIS ADDENDUM to Lease Agreement is attached to and forms a part of that
certain lease dated December 26, 1990, by and between Minneapolis Business Parks
Joint Venture, a California general partnership as Landlord ("Landlord") and
Derata Corporation, as Tenant ("Tenant"), as the same shall modify, amend,
supplement or alter the terms and provisions of said Lease Agreement and by
these presents shall be incorporated therein by reference and form a part
thereof for all purposes.

      In consideration of the Premises, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
Parties hereto further mutually agree as follows:

     1.     Rent.  Subject only to the provisions of paragraphs 5, 6 and 7 of
            ----
this Lease, Tenant shall pay monthly rent in e following amounts during the term
of this Lease.

            (a)   Commencing the later of February 1, 1991, or the Commencement
     Date, as defined hereafter, and continuing for the three successive months
     after the Commencement Date, Tenant shall be responsible for the payment of
     only taxes and operating expenses as defined in Paragraphs 1-7 of the lease
     and estimated at $1,218.00.

            (b)   Commencing after the third successive month following the
     Commencement Date, unless otherwise extended as provided hereafter, and
     continuing through the Termination Date, as defined hereafter, Tenant shall
     pay rent equal to $3,609 payable as follows:  (i) monthly rent equal to
     $2,391 as base rent; and (ii) in addition to and not in lieu of monthly
     rent, taxes and operating expense estimated at $1,218.00

     In the event of any fractional calendar month at the beginning or
termination of the term, Tenant shall pay for each day in such partial month
rent equal to one-thirtieth of the monthly rent and additional rent.

     2.     Commencement Date.  This Lease shall commence February 1, 1991 (the
            -----------------                                                  
"Commencement Date") and terminate April 30, 1996 (the "Termination Date").
Notwithstanding the foregoing, Tenant shall have the right to occupy the office
portion of the Premises on or before January 28, 1991.  In the event that
Landlord completes Tenant Improvements, as defined hereafter, prior to the
Commencement Date, Tenant shall have the right to occupy the Premises pursuant
to the terms and conditions of the Lease, except Tenant shall not be required to
pay any rent prior to the Commencement Date.  Notwithstanding Tenant's early
occupancy of the Premises, the Commencement Date and Termination Date, as
defined herein, shall remain the same.

     In the event that either a portion of or the entire Premises is not ready
for occupancy as of February 1, 1991, the Commencement Date and Termination Date
shall be extended by an amount of time equal to the delay.  Further, Landlord
will be given 30 days to complete the improvements to the space following mutual
execution of this Lease.  Should said improvements not be substantially complete
and, as a result, cause an interruption in Tenant's ability to conduct its
business; then rent shall be abated in an equivalent to the length of said
interruption.

     3.     Parking.  Tenant shall have the temporary exclusive use of 18 
            -------           
parking spaces directly in front of and adjacent to the premises, as
crosshatched on Exhibit B. Landlord and Tenant acknowledge that approximately
half the parking spaces directly adjacent to the premises are a result of the
vacant unleased space adjacent to the premises. In the event this vacant space
is occupied during the term of this lease, the parking spaces directly adjacent
to Tenant's premises may be insufficient to satisfy Tenant's parking as required
by this paragraph. If as a result of the vacant spaces occupancy, Landlord is
unable to provide 18 tenant parking spaces adjacent to the premises and Tenant
demonstrates a need for additional parking either in front of the premises or
adjacent to the premises (including the rear of the building), Landlord will
create additional parking by constructing a parking area on the southside of the
building adjacent to the premises.

     4.     Additional Space.  Tenant shall have the first opportunity to lease,
            ----------------                                                    
for a minimum of 24 months, any available space adjacent to the premises upon
the third anniversary date of the commencement date, provided that such
additional space exceeds 2,000 square feet of the amount of net rentable space
contained in the lease premises.  In the event Tenant requires additional space
of 2,000 square feet and adjacent space is not available to satisfy Tenant's
additional needs, Landlord shall have the right to relocate Tenant to alternate
comparable space which is suitable to satisfy Tenant's needs within the West
Point Business Center Complex.  In the event of such relocation, Landlord shall
be solely responsible for the cost of tenant improvements and reasonable moving
costs necessary to relocate Tenant, and any lease shall be upon the same terms
and conditions contained in this lease including rental on a per square foot
basis for the first two years of occupancy of the new space.  The following
three years of the lease shall be based on the then market rates for comparable
space.  In the event that (i) such additional space is unavailable; or (ii) the
alternate space is not suitable to satisfy Tenant's needs, then Tenant shall
have the right to terminate this lease, provided Tenant gives 
<PAGE>
 
Landlord ninety (90) days written notice prior to such termination. In the event
Tenant terminates this lease, Tenant shall pay Landlord the unamortized portion
of tenant improvements installed by Landlord (as hereafter defined), any
unamortized leasing commission paid, and two (2) months of base rent.

     5.   Tenant Improvements.  Prior to the Commencement Date of this Lease,
          -------------------                                                
Landlord shall construct the following improvements at its sole cost and
expense.

     See Exhibit B and B1 Space Plan.

     Landlord's contractor needs a minimum of thirty (30) days to construct the
space after mutual execution of this lease.

          -----------                                                        
the Lease, Landlord represents and warrants that the HVAC system is in good
order and repair as of the Commencement Date of the Lease.  In the event that
the HVAC system needs any repair during the term of the Leave, and such repair
exceeds $500.00, Landlord and Tenant shall divide the cost of such expense in
the following manner:

          (a)   During lease year 1, Landlord shall pay 100 percent;

          (b)   During least year 2, Landlord shall pay 80 percent and Tenant
     shall pay 20 percent;

          (c)   During lease year 3, Landlord shall pay 60 percent and Tenant
     shall pay 40 percent.

          (d)   During lease year 4, Landlord shall pay 40 percent and Tenant
     shall pay 60 percent; and

          (e)   During lease year 5, Landlord shall pay 20 percent and Tenant
     shall pay 80 percent.

     Tenant further agrees to enter into a maintenance contract with a qualified
     contractor to provide quarterly maintenance to the HVAC units.  Tenant
     shall provide Landlord with a copy of such agreement within thirty (30)
     days of the commencement of this Lease.  Notwithstanding the foregoing,
     Tenant's contribution to such repair shall not exceed $1,500 in any lease
     year.

     7.     Operating Expense.  Notwithstanding anything contained in paragraph
            -----------------                                                  
1(d), operating expense shall exclude:

            (a)   leasing commissions, attorneys' fees, costs and disbursements
     and other expenses incurred in connection with negotiations or disputes
     with tenants, other occupants, or prospective tenants or other occupants of
     the Building;

            (b)   costs of correcting defects in the design or construction of
     the Building or material used in the construction of the Building
     (including latent defects in the Building or the inadequacy of design of
     the Building) or in the Building equipment or appurtenances thereto, except
     that for the purposes of this subparagraph conditions (not occasioned by
     design or construction defects) resulting from ordinary wear and tear and
     use shall not be deemed defects; and

            (c)   costs of Landlord's general corporate overhead and general
     administrative expenses (including but not limited to costs paid to third
     parties to collect rents, prepare tax returns and accounting reports and
     obtain financing) and any expenses related to the formation or continue
     existence of the partnership of Landlord.

     8.   Indemnification.  Tenant shall not be liable to Landlord and Landlord
          ---------------                                                      
hereby waives all claims against Tenant for any injury to or death of any person
or damage to or destruction of property in or about the Building by or from any
cause whatsoever, including without limitation acts of other tenants or third
parties, gas, fire, oil, or electricity, provided that such damage is not the
result of any default or omission of Tenant pursuant to the terms and conditions
of this Lease.  Landlord shall hold Tenant harmless for, from and against and
defend Tenant against any and all claims, liability, damage or loss and for,
from and against all costs and expenses, including reasonable attorneys' fees,
arising out of any injury to or death of person or damage to or destruction of
any property, from any cause whatsoever, except any cause resulting solely from
the negligence or willful act of Tenant, it authorized agents or employees,

the common areas or elsewhere in or about the Building, when such injury or
damage shall be caused in whole or in part by the act, neglect, default or
omission of any duty of Landlord, its agents, employees or invitees.  The
provisions of this paragraph shall survive the termination of this Lease with
respect to any damage, injury or death occurring prior to such termination.

     9.   Consent.  Whenever consent is required by Landlord or Tenant under any

this Agreement; and

     WHEREAS, Medi-Ject and Ethical are parties to an Option Agreement dated

shall request, amounts up to, but not exceeding in aggregate principal amount at
any time outstanding, $312,500.

     2.   Note.  Amounts advanced by Ethical under this Agreement shall be

1994, and the consolidated statements of income and retained earnings and
changes in financial position for the same periods, all as reported on by the
Company's independent certified public accountants (the financial statements
referred to in (a) and (b), together with the notes thereto, are collectively
referred to as the "Financial Statements").   The Financial Statements have, in
all material respects, been prepared in accordance with generally accepted
accounting principles consistently applied, are in accordance with the books and
records of the Company and present fairly the results of its operations for the
periods therein specified and, with respect to the Balance Sheet, the financial
condition of the Company at the Balance Sheet Date.  Without limiting the
generality of the foregoing, the Balance Sheet or notes thereto disclose all of
the debts, liabilities and obligations of any nature (whether absolute, accrued
or contingent and whether due or to become due) of the Company at the Balance
Sheet Date, which, individually or in the aggregate, are material and which in
accordance with generally accepted accounting principles would be required to be
disclosed in such Balance Sheet, and includes appropriate reserves for all taxes
and other liabilities accrued as of such dates but not yet payable.

          (b) The Company has no liability or obligation, which individually or
taken together with any other liability or obligation that is related thereto,
exceeds $50,000, absolute or contingent, including, without limiting the
generality of the foregoing, any tax liabilities due or to become due, not
reflected in the Financial Statements, except (i) obligations and liabilities
incurred after the Balance Sheet Date in the ordinary course of business that
are not, individually or taken together with any other such liability or
obligation that is related thereto, material and (ii) obligations under
contracts made in the ordinary course of business that would not be required to
be reflected in financial statements prepared in accordance with GAAP and (iii)
obligations under this Agreement.  Without limiting the generality of the
foregoing, the Company does not know, and has no reasonable ground to know, of
any basis for the assertion against the Company as of the date hereof of any
material liabilities not reflected in the Financial Statements of the Company.

          (c) Since the Balance Sheet Date, there has been no occurrence,
condition or development that has materially and adversely affected the
Company's 

                                      -4-
<PAGE>
 
business, prospects, condition, affairs, operations, or assets, and there has
been no material change in the business, assets or financial condition of the
Company except pursuant to transactions contemplated by this Agreement or as set
forth on Exhibit B hereto.

          4.6  Tax Returns and Audits.  All tax returns, tax filings and
               ----------------------                                   
appropriate extension requests whatsoever involving the Company, whether
pertaining to foreign or U.S., federal, state or local or any other
jurisdiction, and all taxes, assessments, or similar governmental charges
required to be paid with respect to such returns or other filing have been paid,
or due provision for the payment thereof has been made.  The Company is not and
has not been delinquent in the payment of any such tax or in the payment of any
assessment or governmental charge.  No deficiency assessment or proposed
adjustment of federal income taxes or state or municipal taxes of the Company is
pending, and the Company has no knowledge of any proposed liability for any tax
to be imposed.  The Company has not received notice of any tax deficiency
proposed or assessed against it, and it has not executed any waiver of any
statute of limitations on the assessment or collection of any tax.  The Company
has not received any information from or related to any taxing authority which
would cause it to believe, reasonably, that a notice of any deficiency for any
taxes, or other similar government charges is likely to be issued with respect
to the Company.  The Company does not have any tax liabilities or other similar
government charges except those reflected on the Financial Statements or those
incurred in the ordinary course of business since the Balance Sheet Date.

          4.7  Changes, Dividends, etc.  Except for the transactions
               ------------------------                             
contemplated by this Agreement or except as otherwise disclosed on Exhibit B,
since the Balance Sheet Date, the Company has not: (i) incurred any debts,
obligations or liabilities, absolute, accrued or contingent and whether due or
to become due, except current liabilities incurred in the ordinary course of
business which (individually or in the aggregate) will not materially and
adversely affect the business, properties or prospects of the Company; (ii) paid
any obligation or liability other than, or discharged or satisfied any liens or
encumbrances other than those securing, current liabilities, in each case in the
ordinary course of business; (iii) declared or made any payment to or
distribution to its shareholders as such, or purchased or redeemed any of its
shares of capital stock, or obligated itself to do so; (iv) mortgaged, pledged
or subjected to lien, charge, security interest or other encumbrance any of its
assets, tangible or intangible, except in the ordinary course of business; (v)
sold, transferred or leased any of its assets except in the ordinary course of

pursuant to this Agreement; (x) made any acquisition or 

                                      -5-

disposition of any material assets or became involved in any other material
transaction, other than for fair value in the ordinary course of business; (xi)
increased the compensation payable, or to become payable, to any employees, or
made any bonus payment or similar arrangement with any employees or increased
the scope or nature of any fringe benefits provided for its employees; (xii)
waived any valuable right or a material debt owed to it; (xiii) changed or
amended any material contract or arrangement by which the Company or any of its
assets or properties is bound or subject; or (xiv) agreed to do any of the
foregoing other than pursuant hereto. There has been no material adverse change
in the financial condition, operations, results of operations or business of the
Company since the Balance Sheet Date (other than continued losses from
operations that the Company has incurred, which are generally consistent with
its historical losses from operations since December 31, 1994).

          4.8  Title to Properties and Encumbrances.  The Company has good and
               ------------------------------------                           
marketable title to all of its tangible properties and assets reflected in the
Balance Sheet, except for property disposed of in the ordinary course of
business since the Balance Sheet Date, which properties and assets are not
subject to any mortgage, pledge, lease, lien, charge, security interest,
encumbrance or restriction, except (a) those which are shown and described in
the Financial Statements, (b) liens for taxes and assessments or governmental
charges or levies not at the time due or in respect of which the validity
thereof shall currently be contested in good faith by appropriate proceedings,
or (c) those which do not materially affect the value of or interfere with the
use made of such properties and assets.

Company, threatened against the Company, or any of its officers, directors or
employees (in their capacity as such) or any of the Company's properties, assets
or business nor is the Company aware that there is any reasonable basis for the
foregoing.  The Company is not in default with respect to or a party to or
subject to the provisions of any writ, judgment, order or decree of any court or
any governmental agency or instrumentality.  The Company has not been threatened
with any action or proceeding under any business or zoning ordinance, law or

          4.11  Compliance With Applicable Laws and Other Instruments.  The
                -----------------------------------------------------      
business and operations of the Company have been and are being conducted in all
material respects in accordance with all material, applicable federal, state and
local laws, rules and regulations, with respect to which failure to so comply
would have a 

                                      -6-
<PAGE>
 
material adverse impact upon the Company's business operations, properties or
financial condition or prospects. Neither the execution, delivery and
performance of this Agreement, the Option and the Warrant and the issuance of

Preferred Shares and Series E Preferred Shares including, without limitation,
the provisions of the Certificate of Designations, nor the conduct of the
Company's business as currently conducted or proposed to be conducted as of the
date hereof will conflict with or result in a breach of the terms, conditions or
provisions of, or constitute a default under, or result in any violation of, (a)
the Articles of Incorporation or Bylaws of the Company, (b) any material
mortgage, agreement, understanding or instrument, to which the Company is a
party or (c) any order, judgement, decree, statute, law, rule or regulation
applicable to the Company or its property. The Company is not in default under
any outstanding indenture or other debt instrument or with respect to the
payment of principal of or interest on any outstanding obligations for borrowed
money or in arrears with respect to any dividends upon any shares of its
preferred stock, and there exists no default by the Company under any of its
contracts or agreements, or under any instrument (including without limitation
its Articles of Incorporation and Bylaws) by which the Company is bound, which
materially and adversely affects its business, operations, properties, prospects
or financial condition. To the knowledge of the Company, no employee of the
Company is in violation of any term of any employment contract, patent or other
proprietary information disclosure agreement or any other contract or agreement
relating to the employment of such employee with the Company.

          4.12  Governmental Consent, Etc.  The Company is not required to 
                -------------------------
obtain any consent, approval or authorization of, or to make any declaration or
filing with any governmental authority as a condition to or in connection with
the valid execution, delivery and performance of this Agreement, and the valid

for pursuant to the terms of this Agreement, will be duly authorized, validly
issued and outstanding, fully paid, nonassessable shares and shall be free and
clear of all pledges, liens, encumbrances and restrictions, except as set forth

Conversion Shares, the Option Shares and the Warrant Shares have been duly
authorized and reserved for issuance and, when issued upon conversion of the
Shares, the Option Shares or the Warrant Shares or exercise of the Option or
Warrant, will be duly authorized, validly issued and outstanding, fully paid,

Shares, the Warrant Shares or the Conversion Shares to BD, other than the

other than the filing of a Form D with the Commission. The offer, issuance, sale
and delivery of the Shares, the Option, and the Warrant and, in accordance with
the terms of the Option and Warrant, the Option Shares, the Warrant Shares and
the Conversion Shares, will not, under current laws and regulations, require
compliance with the prospectus delivery or registration requirements of the
federal Securities Act of 1933, as amended (the "Securities Act").  None of the
shares of the Company's capital stock issued and outstanding has been offered or
sold in such a manner as to make the issuance and sale of such shares subject to
such registration requirements, and all such shares of capital stock have been
offered and sold in compliance with all applicable federal and state securities
laws.

          All of the outstanding shares of the Company were duly authorized,

Exhibit B hereto is a complete and correct list of all security holders of
record of the Company,

showing their holdings of issued and outstanding shares of Common Stock or other
Company securities (including warrants and options) as of the date of this
Agreement. Except as set forth on Exhibit B, there are (i) no outstanding
subscriptions, options, warrants, calls, contracts, demands, commitments,

but not limited to, indebtedness with respect to trade accounts, except as set
forth in the Financial Statements.  The Company is not in default in the payment
of the principal of or interest or premium on any such indebtedness, and no
event has occurred or is continuing under the provisions of any instrument,
document or agreement evidencing or relating to any such indebtedness which with
the lapse of time or the giving of notice, or both, would constitute an event of
default thereunder.

          4.18  Performance of Material Agreements.  The Company has

                ----------------------------------------                       
commitment of the Company is in excess of normal, ordinary and usual
requirements of its business, or was made at any price in excess of the then
current market price, or contains terms and conditions more onerous than those
usual and customary in the industry.  There is no outstanding material bid,

Company and its properties and business against such losses and risks, and in
such amounts and with such deductibles, as (a) are consistent with industry

with the transactions contemplated by this Agreement.  The Company will
indemnify, defend and hold BD harmless against any and all liability (including
without limitation, reasonable attorneys' fees and expenses) with respect to any

be payable in connection with the transactions contemplated by this Agreement.

regularly traded on any national securities exchange or in the over-the-counter
market or any payment required to be made by the Company in an amount less than
$2,500 annually.

local or federal, all licenses, permits, authorizations, approvals, franchises

for investment for BD's own account and not with the view to, or for resale in
connection with, any distribution or public offering thereof, except that BD is
contemplating a transfer of the Shares on or before May 31, 1996 to a direct or
indirect subsidiary of BD in a transaction exempt from the registration
requirements of the Securities Act pursuant to which such subsidiary will
represent to BD and the Company in writing that the Shares are being acquired
for investment for such subsidiary's own account and not with the view to, or
for resale in connection with, any distribution or public offering thereof,
which for purposes of this Agreement shall be deemed to be a direct
representation of each of such subsidiary and BD; provided that the disposition

securities laws by reason of their contemplated issuance in transactions exempt

     the Commission is applicable).

          (c) The Company shall not register securities for sale for its own
     account in any registration requested pursuant to Section 10.2 unless
     permitted to do so by the written consent of Initiating Holders who hold at
     least 51% of the shares of Registrable Stock as to which registration has
     been requested.  The Company may not cause any other registration of
     securities for sale for its own account (other than a registration effected
     solely to  implement an employee benefit plan) to be initiated after a
     registration requested pursuant to Section 10.2 and to become effective
     less than 120 days after the effective date of any registration requested
     pursuant to Section 10.2.

          (d) Whenever a requested registration is for an underwritten offering,
     only shares which are to be included in the underwriting may be included in
     the registration.  Notwithstanding the provisions of Sections 10.2(b) and
     10.4(c), if the underwriter determines that (i) marketing factors require a
     limitation of the total number of shares to be underwritten, or (ii) the
     offering price per share would be reduced by the inclusion of the shares of
     the Company, then the number of shares to be included in the registration
     and underwriting shall first be allocated among all Holders who indicated
     to the Company their decision to distribute any of their Registrable Stock
     through such underwriting, in proportion, as nearly as practicable, to the
     respective numbers of shares of Registrable Stock owned by such Holders at
     the time of filing the registration statement, and the remainder, if any,
     to 

                                      -29-
<PAGE>
 
     the Company.  No stock excluded from the underwriting by reason of the
     underwriter's marketing limitation shall be included in such registration.
     If the Company disapproves of any such underwriting, the Company may elect
     to withdraw therefrom by written notice to the Initiating Holders and the
     underwriter.  The securities so withdrawn from such underwriting shall also
     be withdrawn from such registration.

          (e) If at the time of any request to register Registrable Stock
     pursuant to Section 10.2, the Company is engaged, or has fixed plans to
     engage within 90 days of the time of the request, in a registered public
     offering as to which the Holders may include such Stock pursuant to Section
     10.5 or is engaged in any other activity which, in the good faith
     determination of the Company's Board of Directors, would be adversely
     affected by the requested registration to the material detriment of the
     Company, then the Company may at its option direct that such request be
     delayed for a period not in excess of three months from the effective date
     of such offering, or the date of commencement of such other material
     activity, as the case may be, such right to delay a request to be exercised
     by the Company not more than twice while the rights set forth in Section
     10.2 are in effect.

     10.5 Incidental Registration.  If the Company at any time proposes to
          -----------------------                                         
register any of its securities under the Securities Act (other than a
registration effected solely to implement an employee benefit plan or a
transaction to which Rule 145 of the Commission is applicable), it will each
such time give written notice to all Holders of its intention so to do.  Upon
the written request of a Holder or Holders (stating the number of shares of
Registrable Stock to be disposed of by such Holder or Holders and the intended
method of disposition) given within 30 days after receipt of any such notice,
the Company will use its best efforts to cause all such shares of Registrable
Stock intended to be disposed of, the Holders of which shall have requested
registration thereof, to be included in such registration, subject, however, to
the limitations set forth in Section 10.6.

     10.6 Limitations on Incidental Registration.
          -------------------------------------- 

          (a) If any registration pursuant to Section 10.5 shall be underwritten
     in whole or in part, the Company may require that the Registrable Stock
     requested for inclusion pursuant to this Section be included in the
     underwriting on the same terms and conditions as the securities otherwise
     being sold through the underwriters.

          (b) If, in connection with a registration initiated by the Company for
     the sale by it of its securities, the Registrable Stock requested for
     inclusion pursuant to Section 10.5, together with all additional shares of
     all other shareholders that have requested inclusion of their shares (the
     Registrable Stock and all of the other shares requested for inclusion are
     herein together referred to as the "Selling Shareholders' Shares") pursuant
     to the incidental 

                                      -30-
<PAGE>
 
     registration rights granted by the Company prior to the date hereof
     (including permitted transferees and assignees of such incidental
     registration rights), would constitute more than twenty-five percent (25%)
     of the total number of shares to be included in such proposed underwritten
     public offering, and if in the good faith judgment of the managing
     underwriter of such public offering the inclusion of all of the Selling
     Shareholders' Shares originally covered by a request for registration would
     reduce the number of shares to be offered by the Company or interfere with
     the successful marketing of the shares of stock offered by the Company, the
     number of Selling Shareholders' Shares otherwise to be included in the
     underwritten public offering may be reduced pro rata among the holders
     thereof requesting such registration (based upon the number of shares
     requested to be included by each such holder); provided, however, that
     after any such required reduction the Selling Shareholders' Shares to be
     included in such offering shall constitute at least twenty-five percent
     (25%) of the total number of shares to be included in such offering.

          (c) If, in connection with a registration initiated at the request of
     any security holder of the Company pursuant to a demand registration right
     granted to such security holder (the "Requesting Security Holder"), the
     Registrable Stock requested for inclusion pursuant to Section 10.5,
     together with all additional shares of all other shareholders that have
     requested inclusion of their shares (the Registrable Stock and all of the
     other shares requested for inclusion are herein together referred to as the
     "Other Selling Shareholders' Shares") pursuant to the incidental
     registration rights granted by the Company prior to the date hereof
     (including permitted transferees and assignees of such incidental
     registration rights), would reduce the number of shares to be offered by
     the Requesting Shareholder or interfere with the successful marketing of
     the shares of stock offered by the Requesting Shareholder, the number of
     Other Selling Shareholders' Shares otherwise to be included in the
     underwritten public offering may be reduced pro rata among the holders
     thereof requesting such registration (based upon the number of shares
     requested to be included by each such holder).

          (d) Those Selling Shareholders' Shares or Other Selling Shareholders'
     Shares which are excluded from the underwritten public offering pursuant to
     this Section 10.6 shall be withheld from the market by the holders thereof
     for a period, not to exceed 90 days, which the managing underwriter
     reasonably determines is necessary in order to effect the underwritten
     public offering.

     The registration rights granted under Sections 10.5 and 10.8 shall
terminate as to any Holder or permissible transferees or assignees of such
rights if such person (a) holds one percent (1%) or less of the outstanding
shares of Common Stock of the Company (as an as-converted basis) and (b) would
be permitted to sell all of the Registrable Stock held by him within one three-
month period pursuant to Rule 144.

                                      -31-

     10.7 Designation of Underwriter.  In the case of any registration effected
          --------------------------                                           
pursuant to Section 10.2 or 10.8, Holders of a majority in interest of the
Registrable Stock requested to be registered shall have the right to designate
the managing underwriter in any underwritten offering.  In the case of any
registration initiated by the Company, the Company shall have the right to
designate the managing underwriter in any underwritten offering.

     10.8 Form S-3.  The Company shall register its Common Stock under the
          --------                                                        
Exchange Act as soon as legally permissible following the effective date of the
first registration of any securities of the Company on Form S-1, SB-1 or SB-2,
and the Company shall thereafter effect all qualifications and compliances as
would permit or facilitate the sale and distribution of its stock on Form S-3.
After the Company has qualified for the use of Form S-3, the Holders shall have
the right to request up to six registrations on Form S-3 (such requests shall be
in writing and shall state the number of shares of Registrable Stock to be
disposed of and the intended method of disposition), subject to the limitations
set forth in Sections 10.4(d) and (e) and the following:

          (a) The Company shall not be required to effect a registration
     pursuant to this Section 10.8, unless the Holder or Holders requesting
     registration propose to dispose of shares of Registrable Stock having an
     aggregate expected public offering price (before deduction of underwriting
     discounts and expenses of sale) of at least $500,000.

          (b)  The Company shall not be required to effect a registration
     pursuant to this Section 10.8 more frequently than once every six months.

The Company shall give notice to all Holders of the receipt of a request for
registration pursuant to this Section 10.8, and shall provide a reasonable
opportunity for other Holders to participate in the registration, provided that
if the registration is for an underwritten offering, the terms of paragraph (d)
of Section 8.4 shall apply to all participants in such offering.  Subject to the
foregoing, the Company will use its best efforts to effect promptly the
registration of all shares of Registrable Stock on Form S-3 to the extent
requested by the Holder or Holders thereof.

     10.9 Cooperation by Prospective Sellers.
          ---------------------------------- 

          (a) Each prospective seller of Registrable Stock, and each underwriter
     designated by each such seller, will furnish to the Company such
     information as the Company may reasonably require from such seller or
     underwriter in connection with the registration statement (and the
     prospectus included therein).

          (b) Failure of a prospective seller of Registrable Stock to furnish
     the information and agreements described in this Section 10 shall not
     affect the 

                                      -32-
<PAGE>
 
     obligations of the Company under this Section 10 to remaining sellers who
     furnish such information and agreements, unless, in the reasonable opinion
     of counsel to the Company or the underwriters, such failure impairs or may
     impair the viability of the offering or the legality of the registration
     statement or the underlying offering.

          (c) The Holders holding shares included in the registration statement
     will suspend (until further notice) further sales of such shares after
     receipt of telegraphic or written notice from the Company to suspend sales
     to permit the Company to correct or update a registration statement or
     prospectus or, if the Company reasonably determines that correcting or
     updating the registration statement or prospectus would require disclosure
     of material information which the Company has a bona fide business purpose
     for preserving as confidential, during the time that such suspension is
     necessary so that the registration statement and prospectus will meet the
     requirements of the Securities Act; but the obligations of the Company with
     respect to maintaining any registration statement current and effective
     shall be extended by a period of days equal to the period such suspension
     is in effect.

     At the end of the period during which the Company is obligated to keep the
registration statement current and effective as described in paragraph (b) of
Section 10.3 (and any extensions thereof required by the preceding sentence),
the Holders holding shares included in the registration statement shall
discontinue sales of shares pursuant to such registration statement upon receipt
of notice from the Company of its intention to remove from registration the
shares covered by such registration statement which remain unsold, and such
Holders shall (after written request for such notice, describing the information
required in the response) notify the Company of the number of shares registered
which remain unsold promptly upon receipt of such notice from the Company.

     10.10  Expenses of Registration.  All expenses incurred in effecting any
            ------------------------                                         
registration pursuant to this Section 10, including, without limitation, all
registration and filing fees, printing expenses, expenses of compliance with
blue sky laws, fees and disbursements of counsel for the Company and expenses of
any audits incidental to or required by any such registration, shall be borne by
the Company, except (a) that all underwriting discounts and commissions shall be
borne by the Holders holding the securities registered pursuant to such
registration, pro-rata according to the quantity of their securities so
registered; and (b) the Company shall not be required to pay for any expenses of
any registration proceeding begun pursuant to Section 10.2 if the registration
request is subsequently withdrawn at the request of the Holders of a majority of
the Registrable Securities to be registered (in which case all participating
Holders shall bear such expenses), unless the Holders of a majority of the
Registrable Securities agree to forfeit their right to one demand registration
pursuant to Section 10.2; provided, however, that if immediately prior to the
                          --------  -------                                  
time of such withdrawal, the Holders have learned of a materially adverse 

                                      -33-
<PAGE>
 
change in the condition, business or prospects of the Company from that known to
the Holders at the time of their request, then the Holders shall not be required
to pay any of such expenses and shall retain their rights pursuant to Section
10.2.

     10.11  Indemnification.
            --------------- 

          (a)  To the extent permitted by law, the Company will indemnify each
     Holder requesting or joining in a registration, each agent, officer and
     director of such Holders, each person controlling such Holder, and each
     underwriter and selling broker of the securities so registered
     (collectively, "Representatives" and collectively with each such Holder,
     agent, officer, director or person, "Indemnitees") against all claims,
     losses, damages and liabilities (or actions in respect thereof) arising out
     of or based on any untrue statement (or alleged untrue statement) of a
     material fact contained in any prospectus, offering circular or other
     document incident to any registration, qualification or compliance (or in
     any related registration statement, notification or the like) or any
     omission (or alleged omission) to state therein a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading in the light of the circumstances in which they were made, or
     any violation by the Company of any rule or regulation promulgated under
     the Securities Act applicable to the Company and relating to action or
     inaction required of the Company in connection with any such registration,
     qualification or compliance, and will reimburse each such Indemnitee for
     any legal and any other expenses reasonably incurred in connection with
     investigating or defending any such claim, loss, damage, liability or
     action, provided, however, that the Company will not be liable to any
             --------  -------                                            
     Indemnitee in any such case to the extent that any such claim, loss, damage
     or liability is caused by any untrue statement or omission so made in
     strict conformity with written information furnished to the Company by an
     instrument duly executed by such Indemnitee and stated to be specifically
     for use therein and except that the foregoing indemnity agreement is
     subject to the condition that, insofar as it relates to any such untrue
     statement (or alleged untrue statement) or omission (or alleged omission)
     made in the preliminary prospectus but eliminated or remedied in the
     amended prospectus on file with the Commission at the time the registration
     statement becomes effective or in the amended prospectus filed with the
     Commission pursuant to Rule 424(b) (the "Final Prospectus"), such indemnity
     agreement shall not inure to the benefit of any Representative, if a copy
     of the Final Prospectus was not furnished to the person or entity asserting
     the loss, liability, claim or damage at or prior to the time such
     furnishing is required by the Securities Act; provided, further, that this
                                                   --------  -------           
     indemnity shall not be deemed to relieve any underwriter of any of its due
     diligence obligations; provided, further, that the indemnity agreement
                            --------  -------                              
     contained in this subsection 10.11(a) shall not apply to amounts paid in
     settlement of any such claim, loss, damage, liability or action if such
     settlement is effected without the consent of the Company, which consent
     shall not be unreasonably withheld.

                                      -34-
<PAGE>
 
          (b)  To the extent permitted by law, each Holder requesting or joining
     in a registration and each underwriter of the securities so registered will
     indemnify each other Holder, the Company and its officers and directors and
     each person, if any, who controls any thereof within the meaning of Section
     15 of the Securities Act and their respective successors against all
     claims, losses, damages and liabilities or actions in respect thereof)
     arising out of or based on any untrue statement (or alleged untrue
     statement) of a material fact contained in any prospectus, offering
     circular or other document incident to any registration, qualification or
     compliance (or in any related registration statement, notification or the
     like) or any omission (or alleged omission) to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading in the light of the circumstances in which they were
     made; and will reimburse the Company and each other person indemnified
     pursuant to this paragraph (b) for all legal and any other expenses
     reasonably incurred in connection with investigating or defending any such
     claim, loss, damage, liability or action, provided, however, that this
                                               --------  -------           
     paragraph (b) shall apply only if (and only to the extent that) such
     statement or omission was made in reliance upon and in strict conformity
     with written information (including, without limitation, written negative
     responses to inquiries) furnished to the Company by an instrument duly
     executed by such Holder or underwriter and stated to be specifically for
     use in such prospectus, offering circular or other document (or related
     registration statement, notification or the like) or any amendment or
     supplement thereto and except that the foregoing indemnity agreement is
     subject to the condition that, insofar as it relates to any such untrue
     statement (or alleged untrue statement) or omission (or alleged omission)
     made in the preliminary prospectus but eliminated or remedied in the
     amended prospectus on file with the Commission at the time the registration
     statement becomes effective or in the Final Prospectus, such indemnity
     agreement shall not inure to the benefit of any Representative, if a copy
     of the Final Prospectus was not furnished to the person or entity asserting
     the loss, liability, claim or damage at or prior to the time such
     furnishing is required by the Securities Act; provided, further, that this
                                                   --------  -------           
     indemnity shall not be deemed to relieve any underwriter of any of its due
     diligence obligations; provided, further, that the indemnity agreement
                            --------  -------                              
     contained in this subsection 10.11(b) shall not apply to amounts paid in
     settlement of any such claim, loss, damage, liability or action if such
     settlement is effected without the consent of the Holder, which consent
     shall not be unreasonably withheld; and provided, further, that the
                                             --------  -------          
     obligations of such Holders shall be limited to an amount equal to the
     proceeds to each such Holder of the Registrable Stock sold as contemplated
     herein, unless such claim, loss, damage, liability or action resulted from
     such Holder's fraudulent misconduct.

          (c)  Each party entitled to indemnification hereunder (the
     "indemnified party") shall give notice to the party required to provide

                                      -35-
<PAGE>
 
     indemnification (the "indemnifying party") promptly after such indemnified
     party has actual knowledge of any claim as to which indemnity may be
     sought, and shall permit the indemnifying party (at its expense) to assume
     the defense of any claim or any litigation resulting therefrom, provided
                                                                     --------
     that counsel for the indemnifying party, who shall conduct the defense of
     ----                                                                     
     such claim or litigation, shall be satisfactory to the indemnified party,
     and the indemnified party may participate in such defense at such party's
     expense, and provided, further, the omission by any indemnified party to
                  --------  -------                                          
     give notice as provided herein shall not relieve the indemnifying party of
     its obligations under this Section 10.11, except to the extent that the
     omission results in a failure of actual notice to the indemnifying party
     and such indemnifying party is damaged solely as a result of the failure to
     give notice.  No indemnifying party, in the defense of any such claim or
     litigation, shall, except with the consent of each indemnified party,
     consent to entry of any judgment or enter into any settlement which does
     not include as an unconditional term thereof the giving by the claimant or
     plaintiff to such indemnified party of a release from all liability in
     respect to such claim or litigation.

          (d)  The reimbursement required by this Section 10.11 shall be made by
     periodic payments during the course of the investigation or defense, as and
     when bills are received or expenses incurred.

          (e) The obligation of the Company under this Section 10.11 shall
     survive the redemption or conversion, if any, of the Series C, D and E
     Preferred Shares, the completion of any offering of Registrable Stock in a
     registration statement under this Section 10, or otherwise.

     10.12  Rights Which May Be Granted to Subsequent Holders.
            ------------------------------------------------- 

          (a)  Within the limitations prescribed by this paragraph (a), but not
     otherwise, the Company may grant to subsequent investors in the Company
     rights of incidental registration.  Such rights may only pertain to shares
     of Common Stock, including shares of Common Stock into which any other
     securities may be converted.  Such rights may be granted with respect to
     (i) registrations actually requested by Initiating Holders pursuant to
     Section 10.2, but only in respect of that portion of any such registration
     as remains available after inclusion of all Registrable Stock requested by
     Holders and (ii) registrations initiated by the Company, but only in
     respect of that portion of such registration as is available under the
     limitations set forth in Section 10.6 (which limitations shall apply pro-
     rata to all Holders) and such rights shall be limited in all cases to
     sharing pro-rata in the available portion of the registration in question
     with Holders, such sharing to be based on the number of shares of Common
     Stock held by the respective Holders and held by such other investors, plus
     the number of shares of Common Stock into which other securities held by
     the Holders and such other investors are convertible, 

                                      -36-
<PAGE>
 
     which are entitled to registration rights. With respect to registrations
     which are for underwritten public offerings, "available portion" shall mean
     the portion of the underwritten shares which is available as specified in
     clauses (i) and (ii) of the third sentence of this paragraph (a). Shares
     not included in such underwriting shall not be registered.

          (b)  The Company may not grant to subsequent investors in the Company
     rights of registration upon request unless (i) such rights are limited to
     shares of Common Stock and (ii) such rights shall not become effective
     prior to one year following an Automatic Conversion Event.

     10.13  Transfer of Registration Rights.  The registration rights granted
            -------------------------------                                  
under this Section 10 may be transferred but only to a transferee who shall
acquire not less than 100,000 shares of Registrable Stock (as adjusted for
Recapitalization Events). Notwithstanding any provision of this Section 10.13,
the registration rights granted to the Holders under this Section 10 may not be
assigned to any person or entity which, in the Company's reasonable judgment, is
a competitor of the Company.

of time (not to exceed 180 days) from the effective date of any registration of

managing any underwritten offering of the Company's securities) not to sell,

dispose of any Registrable Stock, other than shares of Registrable Stock
included in the registration, without the prior written consent of the Company
or such underwriters, as the case may be, provided that all officers and
directors of the Company and each holder of more than 2% of the outstanding
Common Stock shall enter into similar agreements.

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

                 ------------                                                  
Shares, the Warrant Shares and the Conversion Shares are only transferable
pursuant to (a) an offering registered under the Securities Act, (b) Rule 144 or
Rule 144A or other exemption under the Securities Act (or any similar rule then
in effect) if such rules are or become available, or (c) subject to the

          11.2 Legend.  Each certificate representing Shares, Option Shares or
               ------                                                         
Warrant Shares shall be endorsed with the following legends:

          "The shares represented by this certificate may not be transferred
          without (i) the opinion of counsel reasonably satisfactory to this
          corporation that such transfer may lawfully be made without
          registration under the Securities Act of 1933, as amended, and all
          applicable state securities laws or (ii) such registration."

          Upon the conversion of any Series C Preferred Shares, unless the
Company receives an opinion of counsel satisfactory to the Company to the effect
that a transfer of such shares may be made without registration or further
restriction or transfer, or unless such shares are being disposed of pursuant to
a registration under the Securities Act, the same legend shall be endorsed on
the certificate evidencing such shares.

          11.3 Removal of Legend.  Any legend endorsed on a certificate
               -----------------                                       
evidencing a security pursuant to Section 11.2 hereof shall be removed, and the
Company shall issue a certificate without such legend to BD (or its nominee,
designee or transferee, as the case may be), if BD delivers to the Company an
opinion of such counsel to the effect that such security is not required by the
Securities Act to continue to bear such legend.

     12.  BD Covenant Not to Buy Shares.  BD covenants that it shall neither buy
          -----------------------------                                         
nor solicit offers to sell any shares of capital stock or any purchase rights to
acquire any shares of capital stock of the Company, from any person, partnership
or entity which is currently a shareholder of the Company on the date of this
Agreement without the prior written consent of the Company, until the later to
occur of (i) an Automatic Conversion Event or (ii) the Warrant is fully
exercised, expires or otherwise terminates unless BD shall first notify the
Company of its intention to purchase any such securities and agree in writing,
in a form reasonably acceptable to the Company, that the number of shares for
which the Option or the Warrant (as BD may elect) may be exercised shall be
reduced by the number of shares so purchased from others.  As used in this
Section 12, BD shall include BD and each of BD's direct and indirect
subsidiaries.

     13.  Termination of Covenants.  The obligations of the Company under
          ------------------------                                       
Articles 7 (other than Section 7.9, 7.13 and 7.16) and 8 of this Agreement,
notwithstanding any provisions hereof apparently to the contrary, shall
terminate and shall be of no further force or effect on the earliest to occur of
(i) the date that the Company completes an offering of shares of its capital
stock to the public pursuant to a registration statement filed with and declared
effective by the Commission pursuant to the Securities Act in which the net
proceeds received by the Company equal or exceed $5,000,000 and the per share
purchase price equals or exceeds $4.00 (as adjusted for stock splits, stock
dividends or other corporate 

                                      -38-

reorganizations), or (ii) the date following the merger of the Company with or
into another corporation, the shares of which are currently registered pursuant
to Section 12 or 15 of the Exchange Act, and following such merger, (A) the
Company continues to be the surviving corporation, (B) the surviving
corporation's common shares are registered pursuant to Section 12 or 15 of the
Exchange Act, and (C) the market value of the Company equals or exceeds $50
million, calculated for purposes of this Section 13, as the product of the
average closing price for the Company's Common Stock during any 20 consecutive
trading days times the total number of outstanding shares of Common Stock
(either such event in clauses (i) or (ii) being referred to as an "Automatic
Conversion Event"). The obligations of the Company under Section 7.13 shall
terminate and be of no further force or effect as of the later of the date the
Warrant is exercised in full, expires or otherwise terminates or the occurrence
as an Automatic Conversion Event.

                -------------------                                       
Agreement shall be binding upon and inure to the benefit of and be enforceable
by the respective successors and assigns of the parties hereto, whether so

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

information of the Company which BD has acquired or become acquainted with or
will acquire or become acquainted with pursuant to the terms of this Agreement
except BD may use such knowledge or information in furtherance of its interests

knowledge or information constitutes a unique and valuable asset of the Company

that any disclosure or other use of such knowledge or information other than for

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

                 ----------------------------    
defaults in any of its obligations under this Agreement or if any representation
or warranty made by or on behalf of such party in this Agreement or in any
certificate, report or other instrument delivered under or pursuant to any term
hereof shall be untrue in any material respect as of the date of this Agreement
or as of the Closing Date or as of the date it was made, furnished or delivered,
the other party may proceed to protect and enforce its rights by suit in equity
or action at law, whether for the specific performance of any term contained in
this Agreement or the Articles of Incorporation of the Company or for an
injunction against the breach of any such term or in furtherance of the exercise
of any power granted in this Agreement or such Articles of Incorporation, or to
enforce any other legal or equitable right of such party or to take any one or
more of such actions. In the event either party brings such an action against
the other, the prevailing party in such dispute shall be entitled to recover
from the losing party all fees, costs and expenses of enforcing any right of
such prevailing party under or with respect to this Agreement or the Restated
Articles of Incorporation of the Company, including without limitation

                                      -41-
<PAGE>
 
such fees and expenses of attorneys and accountants, which shall include,
without limitation, all fees, costs and expenses of appeals.

          (b) Remedies Cumulative; Waiver.  No remedy referred to herein is
              ---------------------------                                  
intended to be exclusive, but each shall be cumulative and in addition to any
other remedy referred to above or otherwise available to either party at law or
in equity.  No express or implied waiver by either party of any default shall be
a waiver of any future or subsequent default.  The failure or delay of either
party in exercising any rights granted it hereunder shall not constitute a
waiver of any such right, and any single or partial exercise of any particular
right by such party shall not exhaust the same or constitute a waiver of any
other right provided herein.

          14.14  Execution and Counterparts.  This Agreement may be executed in
                 --------------------------                                    
any number of counterparts, each of which when so executed and delivered shall
be deemed an original, and such counterparts together shall constitute one
instrument.  Each party shall receive a duplicate original of the counterpart
copy or copies executed by it and by the Company.

          14.15  Severability.  In the event any provision of this Agreement or
                 ------------                                                  
the application of any such provision to any party shall be held by a court of
competent jurisdiction to be contrary to law, the remaining provisions of this
Agreement shall remain in full force and effect.

     If BD is in agreement with the foregoing, please sign the form of
acceptance on the enclosed counterpart of this letter and return the same to the
undersigned.

governed by and construed in accordance with the laws of the State of Minnesota.

     10.02 Prior Agreements.  This Agreement contains the entire Agreement
           ----------------

     10.04     Amendments.  No amendment or modification of this Agreement shall
               ----------                                                       
be deemed effective unless made in writing and signed by the parties hereto.

     10.05     No Waiver.  No term or condition of this Agreement shall be
               ---------                                                  
deemed to have been waived, nor shall there be any estoppel to enforce any
provisions of this Agreement, except by a statement in writing signed by the
party against whom enforcement of the waiver or estoppel is sought.  Any written
waiver shall not be deemed a continuing waiver unless specifically stated, shall

be construed to cover only that duration, extent or activities which may validly
and enforceable be covered.  Executive acknowledges the uncertainty of the law
in this respect and expressly stipulates that this Agreement be given the
construction which renders its provisions valid and enforceable to the maximum
extent (not exceeding its express terms) possible under applicable law.

               ----------

obligations under this Agreement to any corporation, firm or other business
entity with or into which the Company may merge or consolidate, or to which the
Company may sell or transfer all or substantially all of its assets, or of which
50% or more of the equity investment and of the voting control is owned,
directly or indirectly, by, or is under common ownership with, the Company.
After any such assignment by the Company, the Company shall be discharged from
all further liability hereunder and such assignee shall thereafter be deemed to
be the Company for the purposes of all provisions of this Agreement including
this Section 10.

     10.08     Injunctive Relief.  Executive agrees that it would be difficult
               -----------------                                              
to compensate the company fully for damages for any violation of the provisions
of this Agreement, including without limitation the provisions of Sections 5,

be entitled to temporary and permanent injunctive relief to enforce the
provisions of this Agreement and that such relief may be granted without the
necessity of proving actual damages.  This provision with respect to injunctive
relief shall not, however, 


                                      -8-

diminish the right of the Company to claim and recover damages in addition to

and construed in accordance with the laws of the State of Minnesota.

    10.02 Prior Agreements.  This Agreement contains the entire Agreement of the
          ----------------                                                      
parties relating to the subject matter hereof and supersedes all prior
Agreements and understandings with respect to such subject matter, and the
parties hereto have made no Agreements, representations or warranties relating
to the subject matter of this Agreement which are not set forth herein.

    10.03 Withholding Taxes.  The Company may withhold from any benefits payable
          -----------------                                                     
under this Agreement all federal, state, city or other taxes as shall be
required pursuant to any law or governmental regulation or ruling.

    10.04 Amendments.  No amendment or modification of this Agreement shall be
          ----------                                                          
deemed effective unless made in writing and signed by the parties hereto.

    10.05 No Waiver.  No term or condition of this Agreement shall be deemed to
          ---------                                                            
have been waived, nor shall there be any estoppel to enforce any provisions of
this Agreement, except by a statement in writing signed by the party against
whom 


                                      -7-
<PAGE>
 
enforcement of the waiver or estoppel is sought. Any written waiver shall not be

    10.06 Severability.  To the extent any provision of this Agreement shall be
          ------------                                                         
invalid or unenforceable, it shall be considered deleted here from and the
remainder of such provision and of this Agreement shall be unaffected and shall
continue in full force and effect.  In furtherance and not in limitation of the
foregoing, should the duration or geographical extent of, or business activities
covered by, any provision of this Agreement be in excess of that which is valid
and enforceable under applicable law, then such provision shall be construed to
cover only that duration, extent or activities which may validly and enforceable
be covered.  Executive acknowledges the uncertainty of the law in this respect
and expressly stipulates that this Agreement be given the construction which
renders its provisions valid and enforceable to the maximum extent (not
exceeding its express terms) possible under applicable law.

          ----------

that the Company, may, without the consent of Executive, assign its rights and
obligations under this Agreement to any corporation, firm or other business
entity with or into which the Company may merge or consolidate, or to which the
Company may sell or transfer all or substantially all of its assets, or of which
50% or more of the equity investment and of the voting control is owned,
directly or indirectly, by, or is under common ownership with, the Company.
After any such assignment by the Company, the Company shall be discharged from
all further liability hereunder and such assignee shall thereafter be deemed to
be the Company for the purposes of all provisions of this Agreement including
this Section 10.

    10.08 Injunctive Relief.  Executive agrees that it would be difficult to
          -----------------                                                 
compensate the company fully for damages for any violation of the provisions of
this Agreement, including without limitation the provisions of Sections 5, 7,8
and 9.03.  Accordingly, Executive specifically agrees that the Company shall be
entitled to temporary and permanent injunctive relief to enforce the provisions
of this Agreement and that such relief may be granted without the necessity of
proving actual damages.  This provision with respect to injunctive relief shall
not, however, diminish the right of the Company to claim and recover damages in
addition to injunctive relief.

    10.   Miscellaneous.

    10.01 Governing Law.  This Agreement is made under and shall be governed by
          -------------                                                        
and construed in accordance with the laws of the State of Minnesota.

    10.02 Prior Agreements.  This Agreement contains the entire Agreement of the
          ----------------                                                      
parties relating to the subject matter hereof and supersedes all prior
Agreements and understandings with respect to such subject matter, and the
parties hereto have made no Agreements, representations or warranties relating
to the subject matter of this Agreement which are not set forth herein.

    10.03 Withholding Taxes.  The Company may withhold from any benefits payable
          -----------------                                                     
under this Agreement all federal, state, city or other taxes as shall be
required pursuant to any law or governmental regulation or ruling.

    10.04 Amendments.  No amendment or modification of this Agreement shall be
          ----------                                                          
deemed effective unless made in writing and signed by the parties hereto.

    10.05 No Waiver.  No term or condition of this Agreement shall be deemed to
          ---------                                                            
have been waived, nor shall there be any estoppel to enforce any provisions of
this Agreement, except by a statement in writing signed by the party against
whom 

                                      -7-
<PAGE>
 
enforcement of the waiver or estoppel is sought.  Any written waiver shall not

such term or condition for the future or as to any act other than that
specifically waived.

    10.06 Severability.  To the extent any provision of this Agreement shall be
          ------------                                                         
invalid or unenforceable, it shall be considered deleted here from and the
remainder of such provision and of this Agreement shall be unaffected and shall
continue in full force and effect.  In furtherance and not in limitation of the
foregoing, should the duration or geographical extent of, or business activities
covered by, any provision of this Agreement be in excess of that which is valid
and enforceable under applicable law, then such provision shall be construed to
cover only that duration, extent or activities which may validly and enforceable
be covered.  Executive acknowledges the uncertainty of the law in this respect
and expressly stipulates that this Agreement be given the construction which
renders its provisions valid and enforceable to the maximum extent (not
exceeding its express terms) possible under applicable law.

that the Company, may, without the consent of Executive, assign its rights and
obligations under this Agreement to any corporation, firm or other business
entity with or into which the Company may merge or consolidate, or to which the
Company may sell or transfer all or substantially all of its assets, or of which
50% or more of the equity investment and of the voting control is owned,
directly or indirectly, by, or is under common ownership with, the Company.
After any such assignment by the Company, the Company shall be discharged from
all further liability hereunder and such assignee shall thereafter be deemed to
be the Company for the purposes of all provisions of this Agreement including
this Section 10.

    10.08 Injunctive Relief.  Executive agrees that it would be difficult to
          -----------------                                                 
compensate the company fully for damages for any violation of the provisions of
this Agreement, including without limitation the provisions of Sections 5, 7,8
and 9.03.  Accordingly, Executive specifically agrees that the Company shall be
entitled to temporary and permanent injunctive relief to enforce the provisions
of this Agreement and that such relief may be granted without the necessity of
proving actual damages.  This provision with respect to injunctive relief shall
not, however, diminish the right of the Company to claim and recover damages in
addition to injunctive relief.

                             MEDI-JECT CORPORATION
                            1993 STOCK OPTION PLAN


     1.  PURPOSE OF THE PLAN.
         ------------------- 

     This Plan shall be known as the " Medi-Ject Corporation 1993 Stock Option
Plan" and is hereinafter referred to as the "Plan."  The purpose of the Plan is
to aid in maintaining and developing personnel capable of assuring the future
success of Medi-Ject Corporation, a Minnesota corporation (the "Company"), to
offer such personnel additional incentives to put forth maximum efforts for the
success of the business, and to afford them an opportunity to acquire a
proprietary interest in the Company through stock options as provided herein.
Options granted under the Plan may be either incentive stock options ("Incentive
Stock Options") within the meaning of Section 422 of the Internal Revenue Code
of 1986, as amended (the "Code"), or options that do not qualify as Incentive
Stock Options.

     2.  STOCK SUBJECT TO THE PLAN.
         ------------------------- 

     Subject to the provisions of Section 16, the shares of stock to be subject
to options under the Plan shall be shares of the Company's authorized common
stock, $.01 par value (the "Common Stock").  Such shares may be either
authorized but unissued shares, or issued shares that have been reacquired by
the Company.  Subject to the adjustment as provided in Section 12, the maximum
number of shares on which options may be exercised under this Plan shall be
300,000 shares.  If an option under the Plan expires, or for any reason is
terminated or unexercised with respect to any shares, such shares shall again be
available for options thereafter granted during the term of the Plan.

     3.  ADMINISTRATION OF PLAN.
         ---------------------- 

     (a) The Plan shall be administered by the Board of Directors of the Company
or a committee of three or more directors of the Company.  The members of such
committee shall be appointed by and serve at the pleasure of the Board of
Directors.  The group administering the Plan shall be referred to herein as the
"Committee" and shall consist initially of Fred Shapiro, M.D., Mark Derus, and
Ken Evenstad.

     (b) The Committee shall have plenary authority in its discretion, but
subject to the express provisions of this Plan, (i) to determine the purchase
price of the common shares covered by each option, (ii) to determine the
employees to whom and the time or times at which such options shall be granted
and the number of shares to be subject to each option, (iii) to determine the
terms of exercise of each option (including the form of payment to be made upon
exercise), (iv) to accelerate the time at which all or any part of an option may
be exercised, (v) to amend or modify the terms of any option with the consent of
the optionee, (vi) to interpret 
<PAGE>
 
the Plan, (vii) to prescribe, amend and rescind rules and regulations relating
to the Plan, (viii) to determine the terms and provisions of each option
agreement under this Plan (which agreements need not be identical), including
the designation of those options intended to be Incentive Stock Options, and
(ix) to make all other determinations necessary or advisable for the
administration of the Plan, subject to the exclusive authority of the Board of
Directors under Section 13 to amend or terminate the Plan. The Committee's
determinations on the foregoing matters, unless otherwise disapproved by the
Board of Directors of the Company, shall be final and conclusive.

     (c) The Committee shall select one of its members as its Chairperson and
shall hold its meetings at such times and places as it may determine.  A
majority of its members shall constitute a quorum.  All determinations of the
Committee shall be made by not less than a majority of its members.  Any
decision or determination that is set forth in a written document and signed by
all of the members of the Committee shall be fully effective as if it had been
made by a majority vote at a meeting duly called and held.  The granting of an
option pursuant to the Plan shall be effective only if a written agreement shall
have been duly executed and delivered by and on behalf of the Company and the
employee to whom such right is granted.  The Committee may appoint a Secretary
and may make such rules and regulations for the conduct of its business as it
shall deem advisable.

     4.  ELIGIBILITY.
         ----------- 

     Incentive Stock Options may only be granted under this Plan to any full or
part-time employee (which term as used herein includes, but is not limited to,
officers and directors who are also employees) of the Company and of its future
subsidiary corporations (herein called "subsidiaries").  Members of the Board of
Directors of the Company, consultants or independent contractors providing
valuable services to the Company or one of its subsidiaries who are not also
employees thereof shall be eligible to receive options that do not qualify as
Incentive Stock Options.  In determining the persons to whom options shall be
granted and the number of shares subject to each option, the Committee may take
into account the nature of services rendered by the respective employees, their
present and potential contributions to the success of the Company and such other
factors as the Committee in its discretion shall deem relevant.  A person who
has been granted an option under the Plan may be granted additional options
under the Plan if the Committee shall so determine; provided, however, that to
the extent the aggregate fair market value (determined at the time the Incentive
Stock Option is granted) of the stock with respect to which all Incentive Stock
Options are exercisable for the first time by an employee during any calendar
year (under all plans described in Section 422 of the Code of his employer
corporation and its parent and subsidiary corporations described in Section
424(e) or 424(f) of the Code) exceeds $100,000, such options shall be treated as
options which do not qualify as Incentive Stock Options.

     5.  PRICE.
         ----- 

     The option price for all Incentive Stock Options granted under the Plan
shall be determined by the Committee but shall not be less than 100% of the fair
market value of shares of the Common Stock at the date of granting of such
option.  The option price for options granted under the Plan that do not qualify
as Incentive Stock Options shall also be determined by the Committee.  For
purposes of the preceding sentence and for all other valuation purposes under
the Plan, the fair market value of the Common Stock shall be as reasonably
determined by the Committee.  If on the date of grant of any option granted
under the Plan, the Common Stock is not publicly traded, the Committee shall
make a good faith attempt to satisfy the option price requirement of this
Section 5 and in connection therewith shall take such action as it deems
necessary or advisable.

     6.  TERM.
         ---- 

     Each option and all rights and obligations thereunder shall expire on the
date determined by the Committee and specified in the option agreement.  The
Committee shall be under no duty to provide terms of like duration for options
granted under the Plan, but the term of any options granted under the Plan may
not extend more than ten (10) years from the date of granting of such option.

     7.  EXERCISE OF OPTION OR AWARD.
         --------------------------- 

     (a) The Committee shall have full and complete authority to determine
whether the option will be exercisable in full at any time or from time to time
during the term of the option, or to provide for the exercise thereof in such
installments, upon the occurrence of such events and at such times during the
term of the option as the Committee may determine and specify in the option
agreement.

     (b) The exercise of any option granted hereunder shall only be effective at
such time that the sale of the Common Stock pursuant to such exercise will not
violate any state or federal securities or other laws.

     (c) An optionee electing to exercise an option shall give written notice to
the Company of such election and of the number of shares subject to such
exercise.  The full purchase price of such shares shall be tendered with such
notice of exercise.  Payment shall be made to the Company either in cash
(including check, bank draft or money order), or, at the discretion of the
Committee, (i) by delivering certificates for shares of Common Stock already
owned by the optionee having a fair market value equal to the full purchase
price of the shares, or (ii) a combination of cash and such shares; provided,
however, that an optionee shall not be entitled to tender shares of the Common
Stock pursuant to successive, substantially simultaneous exercises of options
granted under this or any other stock option plan of the Company.  The fair
market value of such shares shall be determined as 

                                      -3-
<PAGE>
 
provided in Section 5. Until such person has been issued a certificate or
certificates for the shares subject to such exercise, he shall possess no rights
as a shareholder with respect to such shares.

     8.  INCOME TAX WITHHOLDING.
         ---------------------- 

     In order to comply with all applicable federal or state income tax laws or
regulations, the Company may take such action as it deems appropriate to ensure
that all applicable federal or state payroll, withholding, income or other
taxes, which are the sole and absolute responsibility of an optionee or grantee
under the Plan, are withheld or collected from such optionee or grantee.  In
order to assist an optionee or grantee in paying all federal and state taxes to
be withheld or collected upon exercise of an option or award which does not
qualify as an Incentive Stock Option hereunder, the Committee, in its absolute
discretion and subject to such additional terms and conditions as it may adopt,
shall permit the optionee or grantee to satisfy such tax obligation by (i)
electing to have the Company withhold a portion of the shares otherwise to be
delivered upon exercise of such option with a fair market value, determined in
accordance with Section 5 herein, equal to such taxes or (ii) delivering to the
Company Common Stock other than the shares issuable upon exercise of such option
or award with a fair market value, determined in accordance with Section 5,
equal to such taxes.

     9.  ADDITIONAL RESTRICTIONS.
         ----------------------- 

     The Committee shall have full and complete authority to determine whether
all or any part of the shares of Common Stock acquired upon exercise of any of
the options granted under the Plan shall be subject to restrictions on the
transferability thereof or any other restrictions affecting in any manner the
optionee's rights with respect thereto, but any such restriction shall be
contained in the agreement relating to such options.

     10.  TEN PERCENT SHAREHOLDER RULE.
          ---------------------------- 

     Notwithstanding any other provision in the Plan, if at the time an option
is otherwise to be granted pursuant to the Plan the optionee owns directly or
indirectly (within the meaning of Section 424(d) of the Code) shares of common
stock of the Company possessing more than ten percent (10%) of the total
combined voting power of all classes of stock of the Company or its parent or
subsidiary corporations (within the meaning of Section 424(e) or 424(f) of the
Code), if any, then any Incentive Stock Option to be granted to such optionee
pursuant to the Plan shall satisfy the requirements of Section 422(c)(7) of the
Code, the option price shall be not less than 110% of the fair market value of
the Common Stock determined as described herein, and such option by its terms
shall not be exercisable after the expiration of five (5) years from the date
such option is granted.

                                      -4-
<PAGE>
 
     11.  NON-TRANSFERABILITY.
          ------------------- 

     No option granted under the Plan shall be transferable by an optionee,
otherwise than by will or the laws of descent or distribution.  During the
lifetime of an optionee the option shall be exercisable only by such optionee.

     12.  DILUTION OR OTHER ADJUSTMENTS.
          ----------------------------- 

     If there shall be any change in the shares of the Common Stock through
merger, consolidation, reorganization, recapitalization, stock dividend (of
whatever amount), stock split or other change in the corporate structure,
appropriate adjustments in the Plan and outstanding options shall be made by the
Committee.  In the event of any such changes, adjustments shall include, where
appropriate, changes in the aggregate number of shares subject to the Plan, the
number of shares and the price per share subject to outstanding options, in
order to prevent dilution or enlargement of option rights.

     13.  AMENDMENT OR DISCONTINUANCE OF PLAN.
          ----------------------------------- 

     The Board of Directors may amend or discontinue the Plan at any time.  No
amendment of the Plan, however, shall, without shareholder approval:  (i)
increase the maximum number of shares under the Plan as provided in Section 2,
(ii) decrease the minimum option price provided in Section 5, (iii) extend the
maximum option term under Section 6, or (iv) materially modify the eligibility
requirements for participation in the Plan.  The Board of Directors shall not
alter or impair any option theretofore granted under the Plan without the
consent of the holder of the option.

     14.  TIME OF GRANTING.
          ---------------- 

     Nothing contained in the Plan or in any resolution adopted or to be adopted
by the Board of Directors or by the shareholders of the Company, and no action
taken by the Committee or the Board of Directors (other than the execution and
delivery of an option), shall constitute the granting of an option hereunder.

     15.  NO GUARANTY OF EMPLOYMENT.
          ------------------------- 

     Nothing in the Plan or in any agreement thereunder shall confer on any
employee any right to continue in the employ of the Company or any of its
subsidiaries or affect, in any way, the right of the Company or any of its
subsidiaries to terminate any employee's employment at any time.

                                      -5-

     16.  EFFECTIVE DATE AND TERMINATION OF PLAN.
          -------------------------------------- 

     (a) The Plan was approved by the Board of Directors on July 15, 1993, and
shall be approved by the shareholders of the Company as soon as practicable but
in no event later than within twelve (12) months thereof.

     (b) Unless the Plan shall have been discontinued as provided in Section 13,
the Plan shall terminate July 15, 2003.  No option may be granted after such
termination, but termination of the Plan shall not, without the consent of the
optionee, alter or impair any rights or obligations under any option theretofore
granted.

                             MEDI-JECT CORPORATION
                                    FORM OF
                        INCENTIVE STOCK OPTION AGREEMENT


     This Agreement is made and entered into this __ day of _____, ___, between
Medi-Ject Corporation, a Minnesota corporation (the "Company"), and
______________, an individual resident of the State of ________ ("Employee").

     WHEREAS, the Company has adopted the Medi-Ject Corporation 1993 Stock
Option Plan (the "Plan"), which permits issuance of stock options for the
purchase of shares of the Company's common stock, $.01 par value (the "Common
Stock"), and the Company has taken all necessary actions to grant the following
option pursuant and subject to the terms of the Plan.

     NOW, THEREFORE, for good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the Company and Employee hereby agree
as follows:

     1.  Grant of Option.  The Company hereby grants Employee, on the date set
         ---------------                                                      
forth above, the right and option (hereinafter called the "Option") to purchase
all or any part of an aggregate of _______ (____) shares of Common Stock at the
option price of _______ ($___) per share on the terms and conditions set forth
in this Option Agreement and in the Plan.  It is understood and agreed that the
option price is not less than the per share fair market value of such shares on
the date of this Agreement.  The Company intends that the Option shall be an
Incentive Stock Option governed by the provisions of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code").  The terms of the Plan and the
Option shall be interpreted and administered so as to satisfy the requirements
of the Code.  A copy of the Plan will be furnished upon request of Employee.

     2.  Vesting of Option Rights.  The Option shall not be exercisable by
         ------------------------                                         
Employee immediately upon the date of grant.  As otherwise provided in Section 3
of this Agreement, the Option may be exercised by Employee in accordance with
the following schedule:

                                       Cumulative percentage of
     On or after each of                shares with respect to
     the following dates            which the Option is exercisable
     -------------------            -------------------------------
                                                   %

     Notwithstanding the foregoing, the Option may be exercised as to 100% of
the shares of Common Stock for which the Option was granted on the date of a
"change of control", as hereinafter defined.  A "change in control" shall mean
any of the following:
<PAGE>
 
     (i)    A sale of all or substantially all of the assets of the Company;

     (ii)   The acquisition within any rolling twelve-month period of more than
            80% of the Common Stock by any person or group of persons, except a
            Permitted Shareholder as hereinafter defined, acting in concert. A
            "Permitted Shareholder" means a holder, as of the date the Plan was
            adopted by the Company, of Common Stock;

     (iii)  A reorganization of the Company wherein the holders of Common Stock
            receive stock in another company, a merger of the Company with
            another company wherein there is an 80% or greater change in the
            ownership of the Common Stock as a result of such merger, or any
            other transaction in which the Company (other than as the parent
            corporation) is consolidated for federal income tax purposes or is
            eligible to be consolidated for federal income tax purposes with
            another corporation;

     (iv)   In the event that the Common Stock is traded on an established
            securities market: a public announcement that any person has
            acquired or has the right to acquire beneficial ownership of more
            than 50% of the then outstanding Common Stock and for this purpose
            the terms "person" and "beneficial ownership" shall have the
            meanings provided in Section 13(d) of the Securities and Exchange
            Act of 1934 or related rules promulgated by the Securities and
            Exchange Commission or; the commencement of or public announcement
            of an intention to make a tender offer for more than 50% of the then
            outstanding Common Stock; and

     (v)    The Board of Directors of the Company, in its sole and absolute
            discretion, determines that there has been a sufficient change in
            the share ownership of the Company to constitute a change of
            effective ownership or control of the Company.

Employee understands that to the extent that the aggregate fair market value
(determined at the time the Option was granted) of the Common Stock with respect
to which all options, that are incentive stock options within the meaning of
Section 422 of the Code, are exercisable for the first time by Employee during
any calendar year exceed $100,000, in accordance with Section 422(d) of the
Code, such options shall be treated as options that do not qualify as incentive
stock options.

                                      -2-
<PAGE>
 
     The Option shall terminate at the close of business on ______, _____ or
such shorter period as is prescribed herein.  Employee shall not have any of the
rights of a shareholder with respect to the shares subject to the Option until
such shares shall be issued to Employee upon the proper exercise of the Option.

     3.  Exercise of Option after Death or Termination of Employment.  The
         -----------------------------------------------------------      
Option shall terminate and may no longer be exercised if Employee ceases to be
employed by the Company or its subsidiaries, except that:

          (a) If Employee's employment shall be terminated for any reason,
     voluntary or involuntary, other than death, disability (as set forth in
     section 3(c)) or Employee's gross and willful misconduct, then Employee may
     at any time within a period of three (3) months after such termination
     exercise the Option to the extent the Option was exercisable by Employee on
     the date of the termination of Employee's employment;

          (b) If Employee's employment is terminated as a result of Employee's
     gross and willful misconduct, including but not limited to wrongful
     appropriation of funds or the commission of a gross misdemeanor or felony,
     the Option shall be terminated as of the date of the misconduct; and

          (c) If Employee dies in the employ of the Company or a subsidiary or
     Employee's employment is terminated because Employee has become disabled
     (within the meaning of Code section 22(e)(3)) while in the employ of the
     Company or a subsidiary, the Option may, within twelve (12) months after
     Employee's death or the date of termination for such disability, be
     exercised to the extent that Employee was entitled to exercise the Option
     on the date of Employee's death or termination of employment, if earlier,
     by Employee or Employee's personal representatives, if applicable, or by
     the person or persons to whom Employee's rights under the Option pass by
     will or by the applicable laws of descent and distribution;

provided, however, that the Option may not be exercised to any extent by anyone
after the termination date of the Option.

          4.  Investment Representation.  Employee hereby represents and agrees
              -------------------------
that any shares of Common Stock which Employee may acquire pursuant to the
exercise of the Option will be acquired for long-term investment purposes and
not with the view toward the distribution or sale thereof in a public offering
within the meaning of the federal Securities Act of 1933. Employee acknowledges
that at the time of acquisition such shares will not be registered under either
the federal or applicable state securities laws, and that the Company will be
relying upon the foregoing investment representation in agreeing to issue such
shares to Employee. Employee acknowledges that the transferability of such
shares will be subject to restrictions imposed by all applicable federal and
state securities laws and agrees that 

                                      -3-
<PAGE>
 
the certificates evidencing such shares may be imprinted with an appropriate
legend setting forth these restrictions on transferability.

          5.  Method of Exercise of Option.  Subject to the foregoing, the 
              ----------------------------
Option maybe exercised in whole or in part from time to time by serving written
notice of exercise on the Company at its principal office in Minneapolis,
Minnesota. The notice shall set forth the number of shares as to which the
Option is being exercised and shall be accompanied by payment of the purchase
price. Payment of the purchase price shall be made by check payable to the order
of Company; or, at the discretion of the Company, (i) by delivering to the
Company for cancellation shares of Common Stock already owned by Employee having
a fair market value equal to the full purchase price of the shares being
acquired, or (ii) a combination of cash and such shares. The fair market value
of such shares shall be determined as provided in Section 5 of the Plan.

          6.  Miscellaneous.
              ------------- 

          (a) This Agreement shall not confer on Employee any right with respect
to continuance of employment with the Company or any subsidiary of the Company,
nor will it interfere in any way with the right of the Company to terminate such
employment at any time. Neither Employee nor his legal representative, legatees
or distributees, as the case may be, will be or will be deemed to be the holder
of any shares subject to the Option unless and until the Option has been
exercised and the purchase price of the shares purchased has been paid.

          (b) The Option may not be transferred, except by will or the laws of
descent and distribution to the extent provided in paragraph (c) of Section 3,
and during Employee's lifetime the Option is exercisable only by Employee.

          (c) If there shall be any change in the Common Stock subject to the
Option through merger, consolidation, reorganization, recapitalization, stock
dividend, stock split or other change in the corporate structure of the Company,
appropriate adjustments shall be made by the Company in the number of shares and
the price per share of the shares subject to the Option in order to prevent
dilution or enlargement of the option rights granted hereunder.

          (d) The Company shall at all times during the term of the Option
reserve and keep available such number of shares of Common Stock as will be
sufficient to satisfy the requirements of this Agreement.

          (e)  If Employee shall dispose of any of the shares of Common Stock
acquired upon exercise of the Option within two (2) years from the date the
Option was granted or within one (1) year after the date of exercise of the
Option, then, in order to provide the Company with the opportunity to claim the
benefit of any income tax deduction, Employee shall promptly notify the Company
of the dates of acquisition and disposition of such shares, the number of shares
so disposed of, and 

                                      -4-
<PAGE>
 
the consideration, if any, received for such shares. In order to comply with all
applicable federal or state income tax laws or regulations, the Company may take
such action as it deems appropriate to insure (i) notice to the Company of any
disposition of the shares of Common Stock acquired upon exercise of the Option
within the time periods described above and (ii) that, if necessary, all
applicable federal or state payroll, withholding, income or other taxes are
withheld or collected from Employee.

          (f) Employee agrees to disclose neither the contents nor any of the
terms and conditions of this Option to any other person, other than Employee's
legal or tax advisors, heirs or the persons who will be Employee's personal
representative upon Employee's death or legal incapacity.

          IN WITNESS WHEREOF, the Company and Employee have executed this
Agreement as of the date set forth in the first paragraph.

     THIS AGREEMENT, made as of the __ day of _____, ____, between Medi-Ject
Corporation, a Minnesota corporation (the "Company"), and ________ ("Optionee").

     WITNESSETH, THAT:

     WHEREAS, the Company has adopted the Medi-Ject Corporation 1993 Stock
Option Plan (the "Plan"), which permits issuance of stock options for the
purchase of shares of the Company's common stock, $.01 par value (the "Common
Stock"), and the Company has taken all necessary actions to grant the following
option pursuant and subject to the terms of the Plan.

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

     1.  Grant of Option.  The Company hereby grants Optionee, on the date set
         ---------------                                                      
forth above, the right and option (hereinafter called the "Option") to purchase
all or any part of an aggregate of _________ (____) shares of Common Stock at
the option price of ______ ($___) per share on the terms and conditions set
forth in this Option Agreement and in the Plan.   The Option is not intended to
be an incentive stock option within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code").  A copy of the Plan will be
furnished upon request of Optionee.

     2.  Duration and Exercisability.
         --------------------------- 

     (a) Commencing upon the date of grant (the "Normal Exercise Date") and
subject to the other terms and conditions set forth herein, the Option may be
exercised by Optionee in full; provided, however, that the Option shall be
exercisable by Optionee prior to the Normal Exercise Date in cumulative
installments as follows:

                                    Cumulative percentage
     On or after each of            of shares as to which
     the following dates            Option is exercisable
     -------------------            ---------------------
                                               %
 

     The Option shall terminate at the close of business on ____, ___ or such
shorter period as is prescribed herein.  Optionee shall not have any of the
rights of a shareholder with respect to the shares subject to the Option until
such shares shall be issued to Optionee upon the proper exercise of the Option.
<PAGE>
 
          (b)  During the lifetime of Optionee, the Option shall be exercisable
only by Optionee and shall not be assignable or transferable by Optionee, other
than by will or the laws of descent and distribution.

     Notwithstanding the foregoing, the Option may be exercised as to 100% of
the shares of Common Stock for which the Option was granted on the date of a
"change of control", as hereinafter defined.  A "change in control" shall mean
any of the following:

     (i)    A sale of all or substantially all of the assets of the Company;

     (ii)   The acquisition within any rolling twelve-month period of more than
80% of the Common Stock by any person or group of persons, except a Permitted
Shareholder as hereinafter defined, acting in concert.  A "Permitted
Shareholder" means a holder, as of the date the Plan was adopted by the Company,
of Common Stock;

     (iii)  A reorganization of the Company wherein the holders of Common Stock
receive stock in another company, a merger of the Company with another company
wherein there is an 80% or greater change in the ownership of the Common Stock
as a result of such merger, or any other transaction in which the Company (other

          3.  Exercise of Option after Death or Termination of Employment.  The
              -----------------------------------------------------------      
Option shall terminate and may no longer be exercised if Optionee ceases to be
employed by the Company or its subsidiaries, except that:

          (a) If Optionee's employment shall be terminated for any reason,
     voluntary or involuntary, other than death, disability (as set forth in
     section 3(c)) or Optionee's gross and willful misconduct, then Optionee may
     at any time within a period of three (3) months after such termination
     exercise the Option to the extent the Option was exercisable by Optionee on
     the date of the termination of Optionee's employment;

          (b) If Optionee's employment is terminated as a result of Optionee's
     gross and willful misconduct, including but not limited to wrongful
     appropriation of funds or the commission of a gross misdemeanor or felony,
     the Option shall be terminated as of the date of the misconduct; and

          (c) If Optionee dies in the employ of the Company or a subsidiary or
     Optionee's employment is terminated because Optionee has become disabled
     (within the meaning of Code section 22(e)(3)) while in the employ of the
     Company or a subsidiary, the Option may, within twelve (12) months after
     Optionee's death or the date of termination for such disability, be
     exercised to the extent that Optionee was entitled to exercise the Option
     on the date of Optionee's death or termination of employment, if earlier,
     by Optionee or Optionee's personal representatives, if applicable, or by
     the person or persons to whom Optionee's rights under the Option pass by
     will or by the applicable laws of descent and distribution;

provided, however, that the Option may not be exercised to any extent by anyone
after the termination date of the Option.

          4.  Investment Representation.  Optionee hereby represents and agrees
              -------------------------
that any shares of stock which Optionee may acquire pursuant to the exercise of
the Option will be acquired for long-term investment purposes and not with the
view toward the distribution or sale thereof in a public offering within the
meaning of the federal Securities Act of 1933. Optionee acknowledges that at the
time of acquisition such shares will not be registered under either the federal
or applicable state securities laws, and that the Company will be relying upon
the foregoing investment representation in agreeing to issue such shares to
Optionee. Optionee acknowledges that the transferability of such shares will be
subject to restrictions imposed by all applicable federal and state securities
laws and agrees that the certificates evidencing such shares may be imprinted
with an appropriate legend setting forth these restrictions on transferability.

          5.  Method of Exercise of Option.  Subject to the foregoing, the 
              ----------------------------
Option may be exercised in whole or in part from time to time by serving written
notice of exercise on the Company at its principal office in Minneapolis,
Minnesota. The notice shall set forth the number of shares as to which the
Option is being exercised and shall be accompanied by payment of the purchase
price. Payment of the purchase price shall be made by check payable to the order
of Company; or, at the discretion of the Company, (i) by delivering to the
Company for cancellation shares of Common Stock already owned by Optionee having
a fair market value equal to the full purchase price of the shares being
acquired, or (ii) a combination of cash and such shares. The fair market value
of such shares shall be determined as provided in Section 5 of the Plan.

          6.  Miscellaneous.
              ------------- 

          (a) This Agreement shall not confer on Optionee any right with respect
to continuance of employment with the Company or any subsidiary of the Company,
nor will it interfere in any way with the right of the Company to terminate such
employment at any time. Neither Optionee nor his legal representative, legatees
or distributees, as the case may be, will be or will be deemed to be the holder
of any shares subject to the Option unless and until the Option has been
exercised and the purchase price of the shares purchased has been paid.

          (b) The Option may not be transferred, except by will or the laws of
descent and distribution to the extent provided in paragraph (c) of Section 3,
and during Optionee's lifetime the Option is exercisable only by Optionee.

          (c) If there shall be any change in the Common Stock subject to the
Option through merger, consolidation, reorganization, recapitalization, stock
dividend, stock split or other change in the corporate structure of the Company,
appropriate adjustments shall be made by the Company in the number of shares and
the price per share of the shares subject to the Option in order to prevent
dilution or enlargement of the option rights granted hereunder.

          (d) The Company shall at all times during the term of the Option
reserve and keep available such number of shares of Common Stock as will be
sufficient to satisfy the requirements of this Agreement.

          (e) In order to provide the Company with the opportunity to claim the
benefit of any income tax deduction which may be available to it upon the
exercise of the Option, and in order to comply with all applicable federal or
state income tax laws or regulations, the Company may take such action as it
deems appropriate to insure that, if necessary, all applicable federal or state
payroll, withholding, income or other taxes are withheld or collected from
Optionee.  Optionee may elect to satisfy any federal and state income tax
withholding 

                                      -4-
<PAGE>
 
obligations upon exercise of the Option by (i) having the Company withhold a
portion of its Common Stock otherwise to be delivered upon exercise of the
Option having a fair market value equal to the amount of federal and state
income tax required to be withheld upon such exercise, or (ii) delivering to the
Company shares of its Common Stock other than the shares issuable upon exercise
of the Option with a fair market value equal to such taxes.

          (f) Optionee agrees to disclose neither the contents nor any of the
terms and conditions of this Option to any other person, other than Optionee's
legal or tax advisors, heirs or the persons who will be Optionee's personal
representative upon Optionee's death or legal incapacity.


     IN WITNESS WHEREOF, the parties hereto have caused this agreement to be
executed on the day and year first above written.

Dear Sir:

          Medi-Ject Corporation, a Minnesota corporation (the "Company") agrees
with Enskilda Kapitalforvaltning, a corporation formed under the laws of Sweden
(the "Investor"), as follows:

          1.   Authorization of Issue of Shares.  The Board of Directors of the
               --------------------------------                                
Company has authorized the issue and sale of up to 1,000,000 shares of a new
class of Preferred Stock, such shares to be constituted as a new series of
Preferred Stock, and being designated as the "Non-Voting Series B Convertible
Preferred Stock" (herein referred to as the "Non-Voting Series B Preferred
Shares").  The relative powers, preferences and rights and qualifications,
limitations and restrictions of the Non-Voting Series B Preferred Shares are set
forth in a proposed amendment to the capital stock provisions of the Restated
Articles of Incorporation of the Company (the "Proposed Amendment") in the form
attached hereto as Exhibit A.

          Certain capitalized terms used in this agreement (the "Agreement") are
used as defined herein; references to an article or section are, unless
otherwise specified, to one of the articles or sections of the Agreement and
references to an "Exhibit" are, unless otherwise specified, to one of the
exhibits attached to the Agreement.

          2.   Sale and Purchase Price.  The Company will issue and sell to
               -----------------------

Minneapolis, Minnesota at 10:00 A.M. Minneapolis time on February 1, 1994 or
such other date thereafter as shall be mutually agreeable to Investor and the

Date").

          At the closing, the Company shall deliver to Investor a certificate,
dated the Closing Date, representing the Shares purchased by such Investor on
such date, registered in its name (or in the name of its nominee if it so
specifies to the 
<PAGE>
 
Company at least 48 hours prior to such date) against payment to the Company of
the purchase price of Shares being purchased by such Investor.

          4.   Representations and Warranties by the Company.  In order to
               ---------------------------------------------

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

generally accepted auditing standards, as will enable them to give such reports
or opinions with respect to the financial statements of the Company as will
satisfy the requirements of the Commission in effect at such time with respect
to reports or opinions of accountants (except with regard to the Commission's
requirements for accounting for preferred shares as debt rather than equity).

records of the Company and its subsidiaries (and to make photocopies thereof or
make extracts therefrom), and to discuss the affairs, finances and accounts of
any such corporations with the principal officers of the Company and its
independent public accountants, all at such reasonable times and as often as

     liable in excess of $10,000 in connection with the obligations, securities

               ------- 

               10.1      Events of Default.  Each of the following events shall
                         -----------------
be an event of default (an "Event of Default") for purposes of the Agreement:

               (a) if the Company shall default in any material respect in the
     due and punctual performance of any covenant or agreement in any note,
     bond, indenture, loan agreement, note agreement, mortgage, security
     agreement or other instrument evidencing or related to bank indebtedness of

                                     -19-
<PAGE>
 
     than the period of notice and/or grace, if any, therein specified and shall
     not have been waived;

               (b) (i) if any representation or warranty made by or on behalf of
     the Company in the Agreement or in any certificate, report or other
     instrument delivered under or pursuant to any term hereof shall prove to
     have been untrue or incorrect in any material respect as of the date of the
     Agreement, or (ii) if any report, certificate, financial statement or
     financial schedule or other instrument prepared or purported to be prepared
     by the Company or any officer of the Company hereafter furnished or
     delivered under or pursuant to the Agreement shall prove to be untrue or
     incorrect in any material respect as of the date it was made, furnished or
     delivered; or

               (c) if the Company defaults in the due and punctual performance
     or observance of any covenant contained in the Agreement, and such default
     continue for a period of 15 days after written notice thereof to the
     Company by Investor; provided, however, that an Event of Default shall not
     be deemed to have occurred if, at the end of such 15-day, the Company is
     diligently attempting to cure such default and the existence of such
     default is not materially adversely affecting the business or financial
     condition of the Company.

               10.2      Notice of Defaults.  When, to its knowledge, any Event
                         ------------------         
of Default has occurred or exists, the Company shall give written notice within
ten (10) business days of such Event of Default to Investor. If Investor shall
give any notice or take any other actions in respect of a claimed Event of
Default, the Company will forthwith give written notice thereof to all other
holders of Non-Voting Series B Preferred Shares at the time outstanding,
describing such notice or action and the nature of the claimed Event of Default.

               10.3      Suits for Enforcement.  In case any one or more Events 
                         ---------------------                             
of Default shall have occurred and be continuing, unless such Events of Default
shall have been waived in the manner provided in article 15, Investor may
proceed to protect and enforce its rights under this article 10 by suit in
equity or action at law.  It is agreed that in the event of such action,
Investor shall be entitled to receive all reasonable fees, costs and expenses
incurred, including without limitation such reasonable fees and expenses of
attorneys (whether or not litigation is commenced) and reasonable fees, costs
and expenses of appeals.

               10.4      Remedies Cumulative.  No right, power or remedy 
                         -------------------           
conferred upon Investor hereunder shall be exclusive, and each such right, power
or remedy shall be cumulative and in addition to every other right, power or
remedy, whether conferred hereby or by any such security or now or hereafter
available at law or in equity or by statute or otherwise.

                                     -20-
<PAGE>
 
               10.5      Remedies Not Waived.  No course of dealing between the
                         -------------------                   
Company and Investor and no delay in exercising any right, power or remedy
conferred hereby or by any such security or now or hereafter existing at law or
in equity or by statute or otherwise, shall operate as a waiver of or otherwise
prejudice any such right, power or remedy; provided, however, that this section
shall not be construed or applied so as to negate the provisions and intent of
any statute which is otherwise applicable.

               11.       Registration Rights.
                         -------------------

               11.1      Incidental Registration.  Each time the Company shall
                         -----------------------                              
determine to proceed with the actual preparation and filing of a registration
statement under the Securities Act in connection with the proposed offer and
sale for money of any of its securities by it or any of it security holders, the
Company will give written notice of its determination to Investor.  Upon written
request of Investor, given within 30 days after receipt of any such notice from
the Company, the Company will, except as herein provided, cause all Purchased
Shares (as defined below) for which Investor has so requested registration
thereof, to be included in such registration statement, all to the extent
requisite to permit the sale or other disposition by Investor of the Purchased
Shares to be so registered; provided, however, that nothing herein shall prevent
the Company from, at any time, abandoning or delaying any such registration
initiated by it; provided further, however, that if the Company determines not
to proceed with a registration after the registration statement has been filed
with the Commission and the Company's decision not to proceed is primarily based
upon the anticipated public offering price of the securities to be sold by the
Company, the Company shall promptly complete the registration for the benefit of
Investor should Investor wish to proceed with a public offering of its Purchased
Shares provided Investor agrees to bear all expenses in excess of $25,000
incurred by the Company as the result of such registration after the Company has
decided not to proceed.  If any registration pursuant to this section shall be
underwritten in whole or in part, the Company may require that the Purchased
Shares requested for inclusion pursuant to this section be included in the
underwriting on the same terms and conditions as the securities otherwise being
sold through the underwriters.  In the event that the Purchased Shares requested
for inclusion pursuant to this section would constitute more than twenty-five
percent (25%) of the total number of shares to be included in a proposed
underwritten public offering, and if in the good faith judgment of the managing
underwriter of such public offering the inclusion of all of the Purchased Shares
originally covered by a request for registration would reduce the number of
shares to be offered by the Company or interfere with the successful marketing
of the shares of stock offered by the Company, the number of shares of Purchased
Shares otherwise to be included in the underwritten public offering may be
reduced pro rata among all holders thereof requesting such registration;
provided, however, that after any such required reduction the Purchased Shares
to be included in such offering shall constitute at least twenty-five percent
(25%) of the total number of shares to be included in such offering.  Those
shares of Purchase Shares which are thus excluded from the 

                                     -21-
<PAGE>
 
underwritten public offering shall be withheld from the market by the holders
thereof for a period, not to exceed 60 days, which the managing underwriter
reasonably determines is necessary in order to effect the underwritten pubic
offering.

               11.2      Registration Procedures.  If and whenever the Company 
                         -----------------------      
is required by the provisions of section 11.1 to effect the registration of any
Purchased Shares under the Securities Act, the Company will:

               (a) prepare and file with the Commission a registration statement
     with respect to such securities, and use its best efforts to cause such
     registration statement to become and remain effective for such period as
     may be reasonably necessary to effect the sale of such securities, not to
     exceed six (6) months;

               (b) prepare and file with the Commission such amendments to such
     registration statement and supplements to the prospectus contained therein
     as may be necessary to keep such registration statement effective for such
     period as may be reasonably necessary to effect the sale of such
     securities, not to exceed six (6) months;

               (c) furnish to Investor, to the extent he is participating in
     such registration and to the underwriters of the securities being
     registered such reasonable number of copies of the registration statement,
     preliminary prospectus, final prospectus and such other documents as
     Investor and the underwriters may reasonably request in order to facilitate
     the public offering of such securities;

               (d) use its best efforts to register or qualify the securities
     covered by such registration statement under such state securities or blue
     sky laws of such jurisdictions as Investor may reasonably request within 20
     days following the original filing of such registration statement, except
     that the Company shall not for any purpose be required to execute a general
     consent to service of process or to qualify to do business as a foreign
     corporation in any jurisdiction wherein it is not so qualified;

               (e) notify Investor promptly and confirm such advice in writing:

                   (i) when the registration statement, any pre-effective 
          amendment, the prospectus or any prospectus supplement or post-
          effective amendment to the registration statement has been filed, and
          with respect to the registration statement or any post-effective
          amendment, when the same has become effective,

                                     -22-
<PAGE>
 
                   (ii) of any request by the Commission for amendments or 
          supplements to the registration statement or the prospectus or for 
          additional information,

                   (iii) of the receipt by the Company of any notification with
          respect to the suspension of the qualification of any Purchased Shares
          for sale under the securities or "Blue Sky" laws of any jurisdiction
          or the initiation or threat of any proceeding for such purpose, and

                   (iv) of the existence of any fact which results in the 
          registration statement, the prospectus or any document incorporated
          therein by reference containing an untrue statement of material fact
          or omitting to state a material fact required to be stated therein or
          necessary to make any statement therein not misleading;

               (f) prepare and file with the Commission, promptly upon the
     request of Investor, any amendments or supplements to such registration
     statement or prospectus which, in the opinion of counsel for Investor (and
     concurred in by counsel for the Company), is required under the Securities
     Act or the rules and regulations thereunder in connection with the
     distribution of the Purchased Shares by Investor;

               (g) prepare and promptly file with the Commission and promptly
     notify Investor of the filing of such amendment or supplement to such
     registration statement or prospectus as may be necessary to correct any
     statements or omissions if, at the time when a prospectus relating to such
     securities is required to be delivered under the Securities Act, any event
     shall have occurred as the result of which any such prospectus or any other
     prospectus as then in effect would include an untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein, in the light of the circumstances in which they were
     made, not misleading;

               (h) advise Investor, promptly after it shall receive notice or
     obtain knowledge thereof, of the issuance of any stop order by the
     Commission suspending the effectiveness of such registration statement or
     the initiation or threatening of any proceeding for the purpose and
     promptly use its best efforts to prevent the issuance of any stop order or
     to obtain its withdrawal of such stop order should be issued;

               (i) not file any amendment or supplement to such registration
     statement or prospectus to which Investor shall have reasonably objected on
     the grounds that such amendment or supplement does not comply in all
     material respects with the requirements of the Securities Act or the rules
     and regulations thereunder, after having been furnished with a copy

                                     -23-
<PAGE>
 
     thereof at least five business days prior to the filing thereof, unless in
     the opinion of counsel for the Company the filing of such amendment or
     supplement is reasonably necessary to protect the Company from any
     liabilities under any applicable federal or state law and such filing will
     not violate applicable law; and

               (j) enter into such customary agreements and take all such other
     actions in connection therewith in order to expedite or facilitate the
     disposition of such Purchased Shares, whether or not an underwriting
     agreement is entered into and whether or not the Purchased Shares are to be
     sold in an underwritten offering.

               11.3      Expenses.  With respect to each inclusion of Purchased
                         --------                         
Shares in a registration statement pursuant to section 11.1 (except as otherwise
provided in section 11.1 with respect to registrations terminated by the
Company), the Company shall bear the following fees, costs and expenses: all
registration, filing and NASD fees (or, if applicable, the fees and expenses
incurred in connection with the listing of the securities to be registered on
each securities exchange on which such securities are required to be listed),
printing expenses and disbursements of counsel and accountants for the Company,
fees and disbursements of counsel for the underwriter or underwriters of such
securities (if the Company and/or Investor (as a selling security holder) are
required to bear such fees and disbursements), all internal expenses, the
premiums and other costs of policies of insurance against liability arising out
of the pubic offering, if any, and all legal fees and disbursements and other
expenses of complying with the state securities or blue sky laws of any
jurisdictions in which the securities to be offered are to be registered or
qualified; provided, however, that nothing contained herein shall be deemed to
require the Company to consent to general service of process in any state in
order to qualify its securities for sale therein.  With respect to any
registration, the Company shall bear all fees, costs and expenses including, but
not limited to, those listed above.  Notwithstanding anything to the contrary
contained herein, fees and disbursements of counsel and accountants for Investor
along with any commissions and transfer taxes owing by Investor shall be borne
by Investor.

               11.4      Indemnification.  In the event that any Purchased 
                         ---------------      
Shares are included in a registration statement under section 11.1:

               (a) The Company will indemnify Investor and hold Investor 
     harmless pursuant to the provisions of this article and will indemnify any
     underwriter (as defined in the Securities Act) for Investor and each
     person, if any, who controls such underwriter within the meaning of the
     Securities Act, from and against any and all losses, claims, damages,
     liabilities, costs and expenses (including, but not limited to all legal or
     other expenses reasonably incurred by it in connection with investigating
     or defending any loss, claim, damage, liability, cost and expense and any
     amounts paid in settlement of any litigation, commenced or threatened, if
     such settlement is effected with the 

                                     -24-
<PAGE>
 
     prior written consent of the Company) to which Investor and/or any such
     underwriter or controlling person may become subject under the Securities
     Act or otherwise, insofar as such losses, claims, damages, liabilities,
     costs or expenses are caused by any untrue statement or alleged untrue
     statement of any material fact contained in such registration statement,
     any prospectus contained therein or any amendment or supplement thereto, or
     arise out of or are based upon the omission or alleged omission to state
     therein a material fact required to be stated therein or necessary to make
     the statements therein, in light of the circumstances in which they were
     made, not misleading; provided, however, that the Company will not be
     liable to Investor to the extent that any such loss, claims, damage,
     liability, cost or expense arises out of or is based upon an untrue
     statement or alleged untrue statement or omission or alleged omission so
     made in conformity with information furnished by Investor.

               (b) Investor will indemnify and hold harmless the Company, any
     controlling person and any underwriter from and against any and all losses,
     claims, damages, liabilities, costs or expenses to which the Company or any
     controlling person and/or any underwriter may become subject under the
     Securities Act or otherwise, insofar as such losses, claims, damages,
     liabilities, costs or expenses are caused by any untrue, or alleged untrue
     statement of any material fact contained in such registration statement,
     any prospectus contained therein or any amendment or supplement thereto, or
     arise out of or are based upon the omission or the alleged omission to
     state therein a material fact required to be stated therein or necessary to
     make the statement therein, in light of the circumstances in which they
     were made, not misleading, in each case to the extent, but only to the
     extent, that such untrue statement or alleged untrue statement or omission
     or alleged omission was so made in reliance upon and in strict conformity
     with information furnished by Investor.

               (c)  Promptly after receipt by any indemnified party pursuant to
     the provisions of paragraph (a) or (b) of this section of notice of the
     commencement of any action involving the subject matter of the foregoing
     indemnity provisions, such indemnified party will, if a claim thereof is to
     be made against the indemnifying party pursuant to the provisions of said
     paragraph (a) or (b), promptly notify the indemnifying party of the
     commencement thereof; but the omission to so notify the indemnifying party
     will not relieve it from any liability which it may have to any indemnified
     party otherwise than hereunder.  In case such action is brought against any
     indemnified party and it notifies the indemnifying party of the
     commencement thereof, the indemnifying party shall have the right to
     participate in, and, to the extent that it may wish, jointly with any other
     indemnifying party similarly notified, to assume the defense thereof, with
     counsel satisfactory to such indemnified party; provided, however, if the
     defendants in any action include both the indemnified party and the

                                     -25-
<PAGE>
 
     indemnifying party and there is a conflict of interest which would prevent
     counsel for the indemnifying party from also representing the indemnifying
     party, the indemnified party or parties shall have the right to select
     separate counsel to participate in the defense of such action on behalf of
     such indemnified party or parties.  After notice from the indemnifying
     party to such indemnified party of its election so to assume the defence
     thereof, the indemnifying party will not be liable to such indemnified
     party pursuant to the provisions of said paragraph (a) or (b) for any legal
     or other expense subsequently incurred by such indemnified party in
     connection with the defense thereof other than reasonable costs of
     investigation, unless (i) the indemnified party shall have employed counsel
     in accordance with the proviso of the preceding sentence, (ii) the
     indemnifying party shall not have employed counsel satisfactory to the
     indemnified party to represent the indemnified party within a reasonable
     time after the notice of the commencement of the action, or (iii) the
     indemnifying party has authorized the employment of counsel for the
     indemnified party at the expense of the indemnifying party.

          12.  Restriction on Transfer of Shares.
               --------------------------------- 

               12.1      Restrictions.  The Shares and the Conversion Shares 
                         ------------     
are only transferable pursuant to (a) a public offering registered under the
Securities Act, (b) Rule 144 or Rule 144A under the Securities Act (or any
similar rule then in effect) if such rules are or become available, or (c)
subject to the conditions specified elsewhere in this article 12, and any other
legally available means of transfer.

               12.2      Legend.  Each certificate representing Shares shall be
                         ------                                                
endorsed with the following legend:

          "The shares represented by this certificate may not be transferred
          without (i) the opinion of counsel satisfactory to this corporation
          that such transfer may lawfully be made without registration under the
          Securities Act of 1933, as amended and all applicable state securities
          laws or (ii) such registration."

Upon the conversion of any Shares, unless the Company receives an opinion of
counsel satisfactory to the Company to the effect that a transfer of the
Conversion Shares may be made without registration or further restriction or
transfer, or unless such Conversion Shares are being disposed of pursuant to a
registration under the Securities Act, the same legend shall be endorsed on the
certificate evidencing such Conversion Shares.

               12.3      Removal of Legend.  Any legend endorsed on a 
                         -----------------    
certificate evidencing a security pursuant to section 12.2 hereof shall be
removed, and the Company shall issue a certificate without such legend to
Investor (or its nominee, designee or transferee, as the case may be), if such
security is being disposed of 

                                     -26-
<PAGE>
 
pursuant to a registration under the Securities Act or pursuant to Rule 144,
Rule 144A or any rule, regulation or other exemption then in effect or if
Investor (or its designee or proposed transferee) provides the Company with an
opinion of counsel satisfactory to the Company to the effect that a transfer of
such security may be made pursuant to Rule 144, Rule 144A or any rule,
regulation or other exemption then in effect, without registration. In addition,
if Investor delivers to the Company an opinion of such counsel to the effect
that no subsequent transfer of such security will require registration under the
Securities Act, the Company will promptly upon such contemplated transfer
deliver new certificates evidencing such security that do not bear the legend
set forth in section 12.2.

          13.  Investors' Covenant Not to Buy Shares.  Investor, for itself,
               -------------------------------------                        
covenants that it shall neither buy nor solicit offers to sell any shares of
capital stock or any purchase rights to acquire any shares of capital stock of

Articles 7 and 8 of the Agreement, notwithstanding any provisions hereof
apparently to the contrary, shall terminate and shall be of no further force or
effect on the earliest to occur of (i) the date that the Company completes an
offering of shares of its capital stock to the public pursuant to a registration
statement filed with and declared effective by the Commission pursuant to the
Securities Act in which the net proceeds received by the Company equal or exceed
$5,000,000 and the per share purchase price equals or exceeds $4.00 (as adjusted
for stock splits, stock dividends or other corporate reorganizations), (ii) the
date following the merger of the Company with or into another corporation, the
shares of which are currently registered pursuant to Section 12 or 15 of the
Securities Exchange Act of 1934, as amended, and following such merger, (A) the
Company continues to be the surviving corporation, (B) the surviving
corporation's common shares are registered pursuant to Section 12 or 15 of the
Securities Exchange Act of 1934, as amended, and (C) the market value of the
Company equals or exceeds $5 million, calculated for purposes of this section
14, as the product of the average closing price for the Company's Common Stock
during any 20 consecutive trading days times the total number of outstanding
shares of Common Stock or (iii) September 27, 1998.

          15.  Miscellaneous.

to any preemptive rights on the part of any person.  The Company further
covenants and agrees that the Company will at all times have authorized and
reserved a sufficient number of its common shares for the purpose of issue upon
the exercise of such conversion privilege.

               9.3   Adjustment of Number of Shares and Conversion Price.  The

time to time as set forth in the Company's Articles of Incorporation.

               10.1  Events of Default. Each of the following events shall be an
                     -----------------
event of default (an "Event of Default") for purposes of the Agreement:

               (a) if the Company shall default in any material respect in the
     due and punctual performance of any covenant or agreement in any note,
     bond, indenture, loan agreement, note agreement, mortgage, security
     agreement or other instrument evidencing or related to bank indebtedness of

     not have been waived;


                                     -19-
<PAGE>
 
               (b) (i) if any representation or warranty made by or on behalf of
     the Company in the Agreement or in any certificate, report or other
     instrument delivered under or pursuant to any term hereof shall prove to
     have been untrue or incorrect in any material respect as of the date of the
     Agreement, or (ii) if any report, certificate, financial statement or
     financial schedule or other instrument prepared or purported to be prepared
     by the Company or any officer of the Company hereafter furnished or
     delivered under or pursuant to the Agreement shall prove to be untrue or
     incorrect in any material respect as of the date it was made, furnished or
     delivered; or

               (c) if the Company defaults in the due and punctual performance
     or observance of any covenant contained in the Agreement, and such default
     continue for a period of 15 days after written notice thereof to the
     Company by Investor; provided, however, that an Event of Default shall not
     be deemed to have occurred if, at the end of such 15-day, the Company is
     diligently attempting to cure such default and the existence of such
     default is not materially adversely affecting the business or financial
     condition of the Company.

          10.2      Notice of Defaults.  When, to its knowledge, any Event of
                    ------------------                                       
Default has occurred or exists, the Company shall give written notice within ten
(10) business days of such Event of Default to Investor.  If Investor shall give
any notice or take any other actions in respect of a claimed Event of Default,
the Company will forthwith give written notice thereof to all other holders of
Series B Preferred Shares at the time outstanding, describing such notice or
action and the nature of the claimed Event of Default.

          10.3      Suits for Enforcement.  In case any one or more Events of
                    ---------------------                                    
Default shall have occurred and be continuing, unless such Events of Default
shall have been waived in the manner provided in article 15, Investor may
proceed to protect and enforce its rights under this article 10 by suit in
equity or action at law.  It is agreed that in the event of such action,
Investor shall be entitled to receive all reasonable fees, costs and expenses
incurred, including without limitation such reasonable fees and expenses of
attorneys (whether or not litigation is commenced) and reasonable fees, costs
and expenses of appeals.

          10.4      Remedies Cumulative.  No right, power or remedy conferred
                    -------------------                                      
upon Investor hereunder shall be exclusive, and each such right, power or remedy
shall be cumulative and in addition to every other right, power or remedy,
whether conferred hereby or by any such security or now or hereafter available
at law or in equity or by statute or otherwise.

          10.5      Remedies Not Waived.  No course of dealing between the
                    -------------------                                   
Company and Investor and no delay in exercising any right, power or remedy
conferred hereby or by any such security or now or hereafter existing at law or
in equity or by statute or otherwise, shall operate as a waiver of or otherwise
prejudice 


                                     -20-

any such right, power or remedy; provided, however, that this section shall not
be construed or applied so as to negate the provisions and intent of any statute
which is otherwise applicable.

          11.  Registration Rights.
               ------------------- 

               11.1   Incidental Registration.  Each time the Company shall
                      -----------------------                              
determine to proceed with the actual preparation and filing of a registration
statement under the Securities Act in connection with the proposed offer and
sale for money of any of its securities by it or any of it security holders, the
Company will give written notice of its determination to Investor.  Upon written
request of Investor, given within 30 days after receipt of any such notice from
the Company, the Company will, except as herein provided, cause all shares of
Purchased Shares for which Investor has so requested registration thereof, to be
included in such registration statement, all to the extent requisite to permit
the sale or other disposition by Investor of the Purchased Shares to be so
registered; provided, however, that nothing herein shall prevent the Company
from, at any time, abandoning or delaying any such registration initiated by it;
provided further, however, that if the Company determines not to proceed with a
registration after the registration statement has been filed with the Commission
and the Company's decision not to proceed is primarily based upon the
anticipated public offering price of the securities to be sold by the Company,
the Company shall promptly complete the registration for the benefit of Investor
should Investor wish to proceed with a public offering of its Purchased Shares
provided Investor agrees to bear all expenses in excess of $25,000 incurred by
the Company as the result of such registration after the Company has decided not
to proceed.  If any registration pursuant to this section shall be underwritten
in whole or in part, the Company may require that the Purchased Shares requested
for inclusion pursuant to this section be included in the underwriting on the
same terms and conditions as the securities otherwise being sold through the
underwriters.  In the event that the Purchased Shares requested for inclusion
pursuant to this section would constitute more than twenty-five percent (25%) of
the total number of shares to be included in a proposed underwritten public
offering, and if in the good faith judgment of the managing underwriter of such
public offering the inclusion of all of the Purchased Shares originally covered
by a request for registration would reduce the number of shares to be offered by
the Company or interfere with the successful marketing of the shares of stock
offered by the Company, the number of shares of Purchased Shares otherwise to be
included in the underwritten public offering may be reduced pro rata among all
holders thereof requesting such registration; provided, however, that after any
such required reduction the Purchased Shares to be included in such offering
shall constitute at least twenty-five percent (25%) of the total number of
shares to be included in such offering.  Those shares of Purchase Shares which
are thus excluded from the underwritten public offering shall be withheld from
the market by the holders thereof for a period, not to exceed 60 days, which the
managing underwriter reasonably determines is necessary in order to effect the
underwritten pubic offering.

               11.2   Registration Procedures.  If and whenever the Company is
                      -----------------------                                 
required by the provisions of section 11.1 to effect the registration of any
Purchased Shares under the Securities Act, the Company will:

               (a) prepare and file with the Commission a registration statement
     with respect to such securities, and use its best efforts to cause such
     registration statement to become and remain effective for such period as
     may be reasonably necessary to effect the sale of such securities, not to
     exceed six (6) months;

               (b) prepare and file with the Commission such amendments to such
     registration statement and supplements to the prospectus contained therein
     as may be necessary to keep such registration statement effective for such
     period as may be reasonably necessary to effect the sale of such
     securities, not to exceed six (6) months;

               (c) furnish to Investor, to the extent he is participating in
     such registration and to the underwriters of the securities being
     registered such reasonable number of copies of the registration statement,
     preliminary prospectus, final prospectus and such other documents as
     Investor and the underwriters may reasonably request in order to facilitate
     the public offering of such securities;

               (d) use its best efforts to register or qualify the securities
     covered by such registration statement under such state securities or blue
     sky laws of such jurisdictions as Investor may reasonably request within 20
     days following the original filing of such registration statement, except
     that the Company shall not for any purpose be required to execute a general
     consent to service of process or to qualify to do business as a foreign
     corporation in any jurisdiction wherein it is not so qualified;

               (e) notify Investor promptly and confirm such advice in writing:

                   (i)   when the registration statement, any pre-effective
amendment, the prospectus or any prospectus supplement or post-effective
amendment to the registration statement has been filed, and with respect to the
registration statement or any post-effective amendment, when the same has become
effective,

                   (ii)  of any request by the Commission for amendments or
supplements to the registration statement or the prospectus or for additional
information,

                   (iii) of the receipt by the Company of any notification with
respect to the suspension of the qualification of any Purchased 


                                     -22-
<PAGE>
 
Shares for sale under the securities or "Blue Sky" laws of any jurisdiction or
the initiation or threat of any proceeding for such purpose, and

                   (iv)  of the existence of any fact which results in the
registration statement, the prospectus or any document incorporated therein by
reference containing an untrue statement of material fact or omitting to state a
material fact required to be stated therein or necessary to make any statement
therein not misleading;

               (f) prepare and file with the Commission, promptly upon the
     request of Investor, any amendments or supplements to such registration
     statement or prospectus which, in the opinion of counsel for Investor (and
     concurred in by counsel for the Company), is required under the Securities
     Act or the rules and regulations thereunder in connection with the
     distribution of the Purchased Shares by Investor;

               (g) prepare and promptly file with the Commission and promptly
     notify Investor of the filing of such amendment or supplement to such
     registration statement or prospectus as may be necessary to correct any
     statements or omissions if, at the time when a prospectus relating to such
     securities is required to be delivered under the Securities Act, any event
     shall have occurred as the result of which any such prospectus or any other
     prospectus as then in effect would include an untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein, in the light of the circumstances in which they were
     made, not misleading;

               (h) advise Investor, promptly after it shall receive notice or
     obtain knowledge thereof, of the issuance of any stop order by the
     Commission suspending the effectiveness of such registration statement or
     the initiation or threatening of any proceeding for the purpose and
     promptly use its best efforts to prevent the issuance of any stop order or
     to obtain its withdrawal of such stop order should be issued;

               (i) not file any amendment or supplement to such registration
     statement or prospectus to which Investor shall have reasonably objected on
     the grounds that such amendment or supplement does not comply in all
     material respects with the requirements of the Securities Act or the rules
     and regulations thereunder, after having been furnished with a copy thereof
     at least five business days prior to the filing thereof, unless in the
     opinion of counsel for the Company the filing of such amendment or
     supplement is reasonably necessary to protect the Company from any
     liabilities under any applicable federal or state law and such filing will
     not violate applicable law; and


                                     -23-
<PAGE>
 
               (j) enter into such customary agreements and take all such other
     actions in connection therewith in order to expedite or facilitate the
     disposition of such Purchased Shares, whether or not an underwriting
     agreement is entered into and whether or not the Purchased Shares are to be
     sold in an underwritten offering.

          11.3      Expenses.  With respect to each inclusion of Purchased
                    --------                                              
Shares in a registration statement pursuant to section 11.1 (except as otherwise
provided in section 11.1 with respect to registrations terminated by the
Company), the Company shall bear the following fees, costs and expenses: all
registration, filing and NASD fees (or, if applicable, the fees and expenses
incurred in connection with the listing of the securities to be registered on
each securities exchange on which such securities are required to be listed),
printing expenses and disbursements of counsel and accountants for the Company,
fees and disbursements of counsel for the underwriter or underwriters of such
securities (if the Company and/or Investor (as a selling security holder) are
required to bear such fees and disbursements), all internal expenses, the
premiums and other costs of policies of insurance against liability arising out
of the pubic offering, if any, and all legal fees and disbursements and other
expenses of complying with the state securities or blue sky laws of any
jurisdictions in which the securities to be offered are to be registered or
qualified; provided, however, that nothing contained herein shall be deemed to
require the Company to consent to general service of process in any state in
order to qualify its securities for sale therein.  With respect to any
registration, the Company shall bear all fees, costs and expenses including, but
not limited to, those listed above.  Notwithstanding anything to the contrary
contained herein, fees and disbursements of counsel and accountants for Investor
along with any commissions and transfer taxes owing by Investor shall be borne
by Investor.

          11.4      Indemnification.  In the event that any Purchased Shares are
                    ---------------                                             
included in a registration statement under section 11.1:

          (a) The Company will indemnify Investor and hold Investor harmless
pursuant to the provisions of this article and will indemnify any underwriter
(as defined in the Securities Act) for Investor and each person, if any, who
controls such underwriter within the meaning of the Securities Act, from and
against any and all losses, claims, damages, liabilities, costs and expenses
(including, but not limited to all legal or other expenses reasonably incurred
by it in connection with investigating or defending any loss, claim, damage,
liability, cost and expense and any amounts paid in settlement of any
litigation, commenced or threatened, if such settlement is effected with the
prior written consent of the Company) to which Investor and/or any such
underwriter or controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages, liabilities, costs or
expenses are caused by any untrue statement or alleged untrue statement of any
material fact contained in such registration statement, any prospectus contained
therein or any amendment or supplement thereto, or arise out of 


                                     -24-
<PAGE>
 
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances in which they were made, not misleading; provided,
however, that the Company will not be liable to Investor to the extent that any
such loss, claims, damage, liability, cost or expense arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission so made in conformity with information furnished by Investor.



               (b) Investor will indemnify and hold harmless the Company, any
controlling person and any underwriter from and against any and all losses,
claims, damages, liabilities, costs or expenses to which the Company or any
controlling person and/or any underwriter may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages,
liabilities, costs or expenses are caused by any untrue, or alleged untrue
statement of any material fact contained in such registration statement, any
prospectus contained therein or any amendment or supplement thereto, or arise
out of or are based upon the omission or the alleged omission to state therein a
material fact required to be stated therein or necessary to make the statement
therein, in light of the circumstances in which they were made, not misleading,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was so made in
reliance upon and in strict conformity with information furnished by Investor.

               (c)  Promptly after receipt by any indemnified party pursuant to
the provisions of paragraph (a) or (b) of this section of notice of the
commencement of any action involving the subject matter of the foregoing
indemnity provisions, such indemnified party will, if a claim thereof is to be
made against the indemnifying party pursuant to the provisions of said paragraph
(a) or (b), promptly notify the indemnifying party of the commencement thereof;
but the omission to so notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party otherwise than
hereunder. In case such action is brought against any indemnified party and it
notifies the indemnifying party of the commencement thereof, the indemnifying
party shall have the right to participate in, and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party;
provided, however, if the defendants in any action include both the indemnified
party and the indemnifying party and there is a conflict of interest which would
prevent counsel for the indemnifying party from also representing the
indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to participate in the defense of such action on behalf
of such indemnified party or parties. After notice from the indemnifying party
to such indemnified party of its election so to assume the defence thereof, the



                                     -25-

indemnifying party will not be liable to such indemnified party pursuant to the
provisions of said paragraph (a) or (b) for any legal or other expense
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation, unless (i) the indemnified
party shall have employed counsel in accordance with the proviso of the
preceding sentence, (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after the notice of the commencement of the action, or (iii)
the indemnifying party has authorized the employment of counsel for the
indemnified party at the expense of the indemnifying party.

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

               12.1   Restrictions. The Shares and the Conversion Shares are
                      ------------
only transferable pursuant to (a) a public offering registered under the
Securities Act, (b) Rule 144 or Rule 144A under the Securities Act (or any
similar rule then in effect) if such rules are or become available, or (c)
subject to the conditions specified elsewhere in this article 12, and any other
legally available means of transfer.

               12.2   Legend.  Each certificate representing Shares shall be
                      ------                                                
endorsed with the following legend:

          "The shares represented by this certificate may not be transferred
          without (i) the opinion of counsel satisfactory to this corporation
          that such transfer may lawfully be made without registration under the
          Securities Act of 1933, as amended and all applicable state securities
          laws or (ii) such registration."

Upon the conversion of any Shares, unless the Company receives an opinion of
counsel satisfactory to the Company to the effect that a transfer of the
Conversion Shares may be made without registration or further restriction or
transfer, or unless such Conversion Shares are being disposed of pursuant to a
registration under the Securities Act, the same legend shall be endorsed on the
certificate evidencing such Conversion Shares.

evidencing a security pursuant to section 12.2 hereof shall be removed, and the
Company shall issue a certificate without such legend to Investor (or its
nominee, designee or transferee, as the case may be), if such security is being
disposed of pursuant to a registration under the Securities Act or pursuant to
Rule 144, Rule 144A or any rule, regulation or other exemption then in effect or
if Investor (or its designee or proposed transferee) provides the Company with
an opinion of counsel satisfactory to the Company to the effect that a transfer
of such security may be made pursuant to Rule 144, Rule 144A or any rule,
regulation or other exemption then in effect, without registration.  In
addition, if Investor delivers to the Company an 


                                     -26-
<PAGE>
 
opinion of such counsel to the effect that no subsequent transfer of such
security will require registration under the Securities Act, the Company will

date following the merger of the Company with or into another corporation, the
shares of which are currently registered pursuant to Section 12 or 15 of the
Securities Exchange Act of 1934, as amended, and following such merger, (A) the

     contracts or for professional services or fringe benefits to any officer in
     excess

     of amounts fixed by the Board of Directors of the Company prior to
     any payment to such officer;

               (d) alter the authorized capital stock of the Company as set
     forth in the Company's Articles of Incorporation whether (i) by the
     authorization of additional amounts, classes or series of such capital
     stock, or (ii) by the authorization of any new class of capital stock, or
     (iii) by way of any stock split or combination, or (iv) altering the rights
     and/or preferences of the Series B Preferred Shares;

               (e)  change its fiscal year; or

               (f) make any material change in the nature of its business as

          9.   Conversion of Shares.
               -------------------- 

               9.1  Conversion of Shares.  Each Investor may, at its option,
                    --------------------                                    
from and after the occurrence of such events as are set forth in the relevant
provisions of the Company's Articles of Incorporation, convert the Shares
purchased by it under this Agreement, or any portion thereof, into Conversion
Shares at the rate and upon the terms and conditions and subject to the
adjustments set forth in the Company's Articles of Incorporation.  Each Share
shall be automatically converted into Conversion Shares on such terms and
conditions as are set forth in the Company's Articles of Incorporation.

               9.2  Stock Fully Paid; Reservation of Shares.  The Company
                    ---------------------------------------              
covenants and agrees that all Conversion Shares that may be issued upon the
exercise of the conversion privilege referred to in section 9.1 will, upon
issuance in accordance with the terms of the Company's Articles of Incorporation
be fully paid and nonassessable and free from all taxes, liens and charges
(except for taxes, if any, upon income and applicable transfer taxes) with
respect to the issue thereof, and that the issuance thereof shall not give rise
to any preemptive rights on the part of any person.  The Company further
covenants and agrees that the Company will at all times have authorized and
reserved a sufficient number of its common shares for the purpose of issue upon
the exercise of such conversion privilege.

               9.3  Adjustment of Number of Shares and Conversion Price.  The
                    ---------------------------------------------------      
number of common shares issuable upon conversion of the Shares and the
conversion price with the respect thereto shall be subject to adjustment from
time to time as set forth in the Company's Articles of Incorporation.

          10.   Registration Rights.
                ------------------- 

          10.1  Incidental Registration.  Each time the Company shall
                -----------------------                              
determine to proceed with the actual preparation and filing of a registration
statement under the Securities Act in connection with the proposed offer and
sale for money of any of its securities by it or any of it security holders, the
Company will give written notice of its determination to Calvert. Upon written
request of Calvert, given within 30 days after receipt of any such notice from
the Company, the Company will, except as herein provided, cause all shares of
Purchased Shares for which Calvert has so requested registration thereof, to be
included in such registration statement, all to the extent requisite to permit
the sale or other disposition by Calvert of the Purchased Shares to be so
registered; provided, however, that nothing herein shall prevent the Company
from, at any time, abandoning or delaying any such registration initiated by it;
provided further, however, that if the Company determines not to proceed with a
registration after the registration statement has been filed with the Commission
and the Company's decision not to proceed is primarily based upon the
anticipated public offering price of the securities to be sold by the Company,
the Company shall promptly complete the registration for the benefit of Calvert
should Calvert wish to proceed with a public offering of its Purchased Shares
provided Calvert agrees to bear all expenses in excess of $25,000 incurred by
the Company as the result of such registration after the Company has decided not
to proceed.  If any registration pursuant to this section shall be underwritten
in whole or in part, the Company may require that the Purchased Shares requested
for inclusion pursuant to this section be included in the underwriting on the
same terms and conditions as the securities otherwise being sold through the
underwriters.  In the event that the Purchased Shares requested for inclusion
pursuant to this section would constitute more than twenty-five percent (25%) of
the total number of shares to be included in a proposed underwritten public
offering, and if in the good faith judgment of the managing underwriter of such
public offering the inclusion of all of the Purchased Shares originally covered
by a request for registration would reduce the number of shares to be offered by
the Company or interfere with the successful marketing of the shares of stock
offered by the Company, the number of shares of Purchased Shares otherwise to be
included in the underwritten public offering may be reduced pro rata among all
holders thereof requesting such registration; provided, however, that after any
such required reduction the Purchased Shares to be included in such offering
shall constitute at least twenty-five percent (25%) of the total number of
shares to be included in such offering.  Those shares of Purchase Shares which
are thus excluded from the underwritten public offering shall be withheld from
the market by the holders thereof for a period, not to exceed 60 days, which the
managing underwriter reasonably determines is necessary in order to effect the
underwritten pubic offering.

          10.2  Registration Procedures.  If and whenever the Company is
                -----------------------                                 
required by the provisions of section 10.1 to effect the registration of any
Purchased Shares under the Securities Act, the Company will:



                                     -22-
<PAGE>
 
          (a) prepare and file with the Commission a registration statement with
respect to such securities, and use its best efforts to cause such registration
statement to become and remain effective for such period as may be reasonably
necessary to effect the sale of such securities, not to exceed six (6) months;

          (b) prepare and file with the Commission such amendments to such
registration statement and supplements to the prospectus contained therein as
may be necessary to keep such registration statement effective for such period
as may be reasonably necessary to effect the sale of such securities, not to
exceed six (6) months;

          (c) furnish to Calvert, to the extent it is participating in such
registration and to the underwriters of the securities being registered such
reasonable number of copies of the registration statement, preliminary
prospectus, final prospectus and such other documents as Calvert and the
underwriters may reasonably request in order to facilitate the public offering
of such securities;

          (d) use its best efforts to register or qualify the securities covered
by such registration statement under such state securities or blue sky laws of
such jurisdictions as Calvert may reasonably request within 20 days following
the original filing of such registration statement, except that the Company
shall not for any purpose be required to execute a general consent to service of
process or to qualify to do business as a foreign corporation in any
jurisdiction wherein it is not so qualified;

          (e) notify Calvert promptly and confirm such advice in writing:

              (i)   when the registration statement, any pre-effective
     amendment, the prospectus or any prospectus supplement or post-effective
     amendment to the registration statement has been filed, and with respect to
     the registration statement or any post-effective amendment, when the same
     has become effective,

              (ii)  of any request by the Commission for amendments or
     supplements to the registration statement or the prospectus or for
     additional information,

              (iii) of the receipt by the Company of any notification with
     respect to the suspension of the qualification of any Purchased Shares for
     sale under the securities or "Blue Sky" laws of any jurisdiction or the
     initiation or threat of any proceeding for such purpose, and



                                     -23-
<PAGE>
 
                   (iv)  of the existence of any fact which results in the
     registration statement, the prospectus or any document incorporated therein
     by reference containing an untrue statement of material fact or omitting to
     state a material fact required to be stated therein or necessary to make
     any statement therein not misleading ;

               (f) prepare and file with the Commission, promptly upon the
request of Calvert, any amendments or supplements to such registration statement
or prospectus which, in the opinion of counsel for Calvert (and concurred in by
counsel for the Company), is required under the Securities Act or the rules and
regulations thereunder in connection with the distribution of the Purchased
Shares by Calvert;

               (g) prepare and promptly file with the Commission and promptly
notify Calvert of the filing of such amendment or supplement to such
registration statement or prospectus as may be necessary to correct any
statements or omissions if, at the time when a prospectus relating to such
securities is required to be delivered under the Securities Act, any event shall
have occurred as the result of which any such prospectus or any other prospectus
as then in effect would include an untrue statement of a material fact or omit
to state any material fact necessary to make the statements therein, in the
light of the circumstances in which they were made, not misleading;

               (h) advise Calvert, promptly after it shall receive notice or
obtain knowledge thereof, of the issuance of any stop order by the Commission
suspending the effectiveness of such registration statement or the initiation or
threatening of any proceeding for the purpose and promptly use its best efforts
to prevent the issuance of any stop order or to obtain its withdrawal of such
stop order should be issued;

               (i) not file any amendment or supplement to such registration
statement or prospectus to which Calvert shall have reasonably objected on the
grounds that such amendment or supplement does not comply in all material
respects with the requirements of the Securities Act or the rules and
regulations thereunder, after having been furnished with a copy thereof at least
five business days prior to the filing thereof, unless in the opinion of counsel
for the Company the filing of such amendment or supplement is reasonably
necessary to protect the Company from any liabilities under any applicable
federal or state law and such filing will not violate applicable law; and

               (j) enter into such customary agreements and take all such other
actions in connection therewith in order to expedite or facilitate the
disposition of such Purchased Shares, whether or not an underwriting



                                     -24-
<PAGE>
 
     agreement is entered into and whether or not the Purchased Shares are to be
     sold in an underwritten offering.

          10.3  Expenses.  With respect to each inclusion of Purchased
                --------                                              
Shares in a registration statement pursuant to section 10.1 (except as otherwise
provided in section 10.1 with respect to registrations terminated by the
Company), the Company shall bear the following fees, costs and expenses: all
registration, filing and NASD fees (or, if applicable, the fees and expenses
incurred in connection with the listing of the securities to be registered on
each securities exchange on which such securities are required to be listed),
printing expenses and disbursements of counsel and accountants for the Company,
fees and disbursements of counsel for the underwriter or underwriters of such
securities (if the Company and/or Calvert (as a selling security holder) are
required to bear such fees and disbursements), all internal expenses, the
premiums and other costs of policies of insurance against liability arising out
of the pubic offering, if any, and all legal fees and disbursements and other
expenses of complying with the state securities or blue sky laws of any
jurisdictions in which the securities to be offered are to be registered or
qualified; provided, however, that nothing contained herein shall be deemed to
require the Company to consent to general service of process in any state in
order to qualify its securities for sale therein.  With respect to any
registration, the Company shall bear all fees, costs and expenses including, but
not limited to, those listed above.  Notwithstanding anything to the contrary
contained herein, fees and disbursements of counsel and accountants for Calvert
along with any commissions and transfer taxes owing by Calvert shall be borne by
Calvert.

          10.4  Indemnification.  In the event that any Purchased Shares are
                ---------------                                             
included in a registration statement under section 10.1:

          (a) The Company will indemnify Calvert and hold Calvert harmless
     pursuant to the provisions of this article and will indemnify any
     underwriter (as defined in the Securities Act) for Calvert and each person,
     if any, who controls Calvert or such underwriter within the meaning of the
     Securities Act, from and against any and all losses, claims, damages,
     liabilities, costs and expenses (including, but not limited to all legal or
     other expenses reasonably incurred by it in connection with investigating
     or defending any loss, claim, damage, liability, cost and expense and any
     amounts paid in settlement of any litigation, commenced or threatened, if
     such settlement is effected with the prior written consent of the Company)
     to which Calvert and/or any such underwriter or controlling person may
     become subject under the Securities Act or otherwise, insofar as such
     losses, claims, damages, liabilities, costs or expenses are caused by any
     untrue statement or alleged untrue statement of any material fact contained
     in such registration statement, any prospectus contained therein or any
     amendment or supplement thereto, or arise out of or are based upon the
     omission or alleged omission to state therein a material fact required to
     be stated therein or necessary to make the statements therein, in light of
     the circumstances in

                                     -25-
<PAGE>
 
     which they were made, not misleading; provided, however, that the Company
     will not be liable to Calvert to the extent that any such loss, claims,
     damage, liability, cost or expense arises out of or is based upon an untrue
     statement or alleged untrue statement or omission or alleged omission so
     made in conformity with information furnished by Calvert.

               (b) Calvert will indemnify and hold harmless the Company, any
     controlling person and any underwriter from and against any and all losses,
     claims, damages, liabilities, costs or expenses to which the Company or any
     controlling person and/or any underwriter may become subject under the
     Securities Act or otherwise, insofar as such losses, claims, damages,
     liabilities, costs or expenses are caused by any untrue, or alleged untrue
     statement of any material fact contained in such registration statement,
     any prospectus contained therein or any amendment or supplement thereto, or
     arise out of or are based upon the omission or the alleged omission to
     state therein a material fact required to be stated therein or necessary to
     make the statement therein, in light of the circumstances in which they
     were made, not misleading, in each case to the extent, but only to the
     extent, that such untrue statement or alleged untrue statement or omission
     or alleged omission was so made in reliance upon and in strict conformity
     with information furnished by Calvert.

               (c) Promptly after receipt by any indemnified party pursuant to
     the provisions of paragraph (a) or (b) of this section of notice of the
     commencement of any action involving the subject matter of the foregoing
     indemnity provisions, such indemnified party will, if a claim thereof is to
     be made against the indemnifying party pursuant to the provisions of said
     paragraph (a) or (b), promptly notify the indemnifying party of the
     commencement thereof; but the omission to so notify the indemnifying party
     will not relieve it from any liability which it may have to any indemnified
     party otherwise than hereunder. In case such action is brought against any
     indemnified party and it notifies the indemnifying party of the
     commencement thereof, the indemnifying party shall have the right to
     participate in, and, to the extent that it may wish, jointly with any other
     indemnifying party similarly notified, to assume the defense thereof, with
     counsel satisfactory to such indemnified party; provided, however, if the
     defendants in any action include both the indemnified party and the
     indemnifying party and there is a conflict of interest which would prevent
     counsel for the indemnifying party from also representing the indemnifying
     party, the indemnified party or parties shall have the right to select
     separate counsel to participate in the defense of such action on behalf of
     such indemnified party or parties. After notice from the indemnifying party
     to such indemnified party of its election so to assume the defence thereof,
     the indemnifying party will not be liable to such indemnified party
     pursuant to the provisions of said paragraph (a) or (b) for any legal or
     other expense subsequently incurred by such indemnified party in connection
     with the


                                     -26-
<PAGE>
 
     defense thereof other than reasonable costs of investigation, unless (i)
     the indemnified party shall have employed counsel in accordance with the
     proviso of the preceding sentence, (ii) the indemnifying party shall not
     have employed counsel satisfactory to the indemnified party to represent
     the indemnified party within a reasonable time after the notice of the
     commencement of the action, or (iii) the indemnifying party has authorized
     the employment of counsel for the indemnified party at the expense of the
     indemnifying party.

          10.5  Registration Rights of Transferees.  The registration rights
                ----------------------------------                          
granted pursuant to this article 10 shall also be for the benefit of, and
enforceable by, any subsequent holder of Purchased Shares, whether or not any
express assignment of such rights to any such subsequent holder is made, so long
as such subsequent holder acquires at least twenty-five percent (25% ) of the
Purchased Shares then outstanding.

          11.  Default.
               ------- 

               11.1 Events of Default. Each of the following events shall be an
                    -----------------
event of default (an "Event of Default") for purposes of the Agreement:

               (a) if the Company shall default in any material respect in the
     due and punctual performance of any covenant or agreement in any note,
     bond, indenture, loan agreement, note agreement, mortgage, security
     agreement or other instrument evidencing or related to bank indebtedness of
     the Company in excess of $400,000, and such default shall continue for more
     than the period of notice and/or grace, if any, therein specified and shall
     not have been waived;

               (b) (i) if any representation or warranty made by or on behalf of
     the Company in the Agreement or in any certificate, report or other
     instrument delivered under or pursuant to any term hereof shall prove to
     have been untrue or incorrect in any material respect as of the date of the
     Agreement, or (ii) if any report, certificate, financial statement or
     financial schedule or other instrument prepared or purported to be prepared
     by the Company or any officer of the Company hereafter furnished or
     delivered under or pursuant to the Agreement shall prove to be untrue or
     incorrect in any material respect as of the date it was made, furnished or
     delivered; or

               (c) if the Company defaults in the due and punctual performance
     or observance of any covenant contained in the Agreement, and such default
     continue for a period of 15 days after written notice thereof to the
     Company by the Investors; provided, however, that an Event of Default shall
     not be deemed to have occurred if, at the end of such 15-day, the Company
     is diligently attempting to cure such default and the existence of such
     default is 



                                     -27-
<PAGE>
 
     not materially adversely affecting the business or financial
     condition of the Company.

          11.2  Notice of Defaults.  When, to its knowledge, any Event of
                ------------------                                       
Default has occurred or exists, the Company shall give written notice within ten
(10) business days of such Event of Default to each holder of Series B Preferred
Shares.  If any holder of Series B Preferred Shares shall give any notice or
take any other actions in respect of a claimed Event of Default, the Company
will forthwith give written notice thereof to all other holders of Series B
Preferred Shares at the time outstanding, describing such notice or action and
the nature of the claimed Event of Default.

          11.3  Suits for Enforcement.  In case any one or more Events of
                ---------------------                                    
Default shall have occurred and be continuing, unless such Events of Default
shall have been waived in the manner provided in article 15, the Investors may
proceed to protect and enforce their rights under this article 11 by suit in
equity or action at law.  It is agreed that in the event of such action, the
Investors shall be entitled to receive all reasonable fees, costs and expenses
incurred, including without limitation such reasonable fees and expenses of
attorneys (whether or not litigation is commenced) and reasonable fees, costs
and expenses of appeals.

          11.4  Remedies Cumulative.  No right, power or remedy conferred
                -------------------                                      
upon the Investors hereunder shall be exclusive, and each such right, power or
remedy shall be cumulative and in addition to every other right, power or
remedy, whether conferred hereby or by any such security or now or hereafter
available at law or in equity or by statute or otherwise.

          11.5  Remedies Not Waived.  No course of dealing between the
                -------------------                                   
Company and the Investors and no delay in exercising any right, power or remedy
conferred hereby or by any such security or now or hereafter existing at law or
in equity or by statute or otherwise, shall operate as a waiver of or otherwise
prejudice any such right, power or remedy; provided, however, that this section
shall not be construed or applied so as to negate the provisions and intent of
any statute which is otherwise applicable.

    12.  Restriction on Transfer of Shares.
         --------------------------------- 

          12.1  Restrictions.  The Shares and the Conversion Shares are only
                ------------                                                
transferable pursuant to (a) a public offering registered under the Securities
Act, (b) Rule 144 or Rule 144A under the Securities Act (or any similar rule
then in effect) if such rules are or become available, or (c) subject to the
conditions specified elsewhere in this article 12, and any other legally
available means of transfer.

          12.2 Legend.  Each certificate representing Shares shall be
               ------                                                
endorsed with the following legend:



                                     -28-
<PAGE>
 
          "The shares represented by this certificate may not be transferred
          without (i) the opinion of counsel satisfactory to this corporation
          that such transfer may lawfully be made without registration under the
          Securities Act of 1933, as amended and all applicable state securities
          laws or (ii) such registration."

Upon the conversion of any Shares, unless the Company receives an opinion of
counsel satisfactory to the Company to the effect that a transfer of the
Conversion Shares may be made without registration or further restriction or
transfer, or unless such Conversion Shares are being disposed of pursuant to a
registration under the Securities Act, the same legend shall be endorsed on the
certificate evidencing such Conversion Shares.

          12.3  Removal of Legend.  Any legend endorsed on a certificate
                -----------------                                       
evidencing a security pursuant to section 12.2 hereof shall be removed, and the
Company shall issue a certificate without such legend to an Investor (or its
nominee, designee or transferee, as the case may be), if such security is being
disposed of pursuant to a registration under the Securities Act or pursuant to
Rule 144, Rule 144A or any rule, regulation or other exemption then in effect or
if an Investor (or its designee or proposed transferee) provides the Company
with an opinion of counsel satisfactory to the Company to the effect that a
transfer of such security may be made pursuant to Rule 144, Rule 144A or any
rule, regulation or other exemption then in effect, without registration.  In
addition, if an Investor delivers to the Company an opinion of such counsel to
the effect that no subsequent transfer of such security will require
registration under the Securities Act, the Company will promptly upon such
contemplated transfer deliver new certificates evidencing such security that do
not bear the legend set forth in section 12.2.

     13.  Investors' Covenant Not to Buy Shares.  Each Investor, for
          -------------------------------------                     
itself, covenants that it shall neither buy nor solicit offers to sell any
shares of capital stock or any purchase rights to acquire any shares of capital
stock of the Company, from any person, partnership or entity which is currently
a shareholder of the Company on the date of this Agreement until the earlier to
occur of the events set forth in section 14(i) or (ii) below.

     14.  Termination of Covenants.  The obligations of the Company under
          ------------------------                                       
Articles 7 and 8 of the Agreement, notwithstanding any provisions hereof
apparently to the contrary, shall terminate and shall be of no further force or
effect on the earliest to occur of (i) the date that the Company completes an
offering of shares of its capital stock to the public pursuant to a registration
statement filed with and declared effective by the Commission pursuant to the
Securities Act in which the net proceeds received by the Company equal or exceed
$5,000,000 and the per share purchase price equals or exceeds $4.00 (as adjusted
for stock splits, stock dividends or other corporate reorganizations), (ii) the

          9.  Conversion of Shares.
              -------------------- 

               9.1  Conversion of Shares.  Investor may, at its option, from and
                    --------------------                                        
after the occurrence of such events as are set forth in the relevant provisions
of the Company's Articles of Incorporation, convert the Shares, or any thereof,
into Conversion Shares at the rate and upon the terms and conditions and subject
to the adjustments set forth in the Company's Articles of Incorporation.  Each
Share shall be automatically converted into Conversion Shares on such terms and
conditions as are set forth in the Company's Articles of Incorporation.

               9.2  Stock Fully Paid; Reservation of Shares.  The Company
                    ---------------------------------------              
covenants and agrees that all Conversion Shares that may be issued upon the
exercise of the conversion privilege referred to in section 9.1 will, upon
issuance in accordance with the terms of the Company's Articles of Incorporation
be fully paid and nonassessable and free from all taxes, liens and charges
(except for taxes, if any, upon income and applicable transfer taxes) with
respect to the issue thereof, and that the issuance thereof shall not give rise
to any preemptive rights on the part of any person.  The Company further
covenants and agrees that the Company will at all times have authorized and
reserved a sufficient number of its common shares for the purpose of issue upon
the exercise of such conversion privilege.

               9.3  Adjustment of Number of Shares and Conversion Price. The
                    ---------------------------------------------------     
number of common shares issuable upon conversion of the Shares and the
conversion price with the respect thereto shall be subject to adjustment from
time to time as set forth in the Company's Articles of Incorporation.

           10.  Registration Rights.
                ------------------- 

               10.1  Required Registration.  If, after one year from the Closing
                     ---------------------                                      
Date, the Company receives a written request from Investor, the Company shall
prepare and file a registration statement under the Securities Act covering the
Purchased Shares (as defined in section 15.9 hereof) which are the subject of
such request and shall use its best efforts to cause such registration statement
to become effective.  Notwithstanding the foregoing, the Company may (a) elect
not to proceed with such registration if the price at which such shares are to
be sold pursuant to such registration statement is less than $4.00 per share (as
adjusted for any stock splits, stock dividends or other corporate
reorganizations), or (b) postpone the effective date of any such registration to
a date which is no more than 180 days after the effective date of any
registration filed by the Company prior to or within thirty (30) days after the
receipt of the written request from Investor.  The Company shall be obligated to
prepare, file and cause to become effective only one (1) registration statement
pursuant to this section 10.1; notwithstanding the foregoing, Investor may
require, pursuant to this section 10.1, the Company to file any number of
registration statements on Form S-3 (or any successor form subsequently
promulgated by the Commission as a replacement for Form S-3) if such form is
then 

                                     -23-
<PAGE>
 
available for use by the Company and Investor. In the event that (a) Investor
determines for any reason not to proceed with a registration at any time before
the registration statement has been declared effective by the Commission, and
Investor requests the Company to withdraw such registration statement, if
theretofore filed with the Commission, is withdrawn with respect to the
Purchased Shares covered thereby, and (b) Investor agrees to bear its own
expenses incurred in connection therewith and to reimburse the Company for the
expenses incurred by it attributable to the registration of such Purchased
Shares, then Investor shall not be deemed to have exercised its right to require
the Company to register securities pursuant to this section 10.1.

               Without the written consent of Investor, neither the Company nor
any other holder of securities of the Company may include securities in such
registration if in the good faith judgement of the managing underwriter of such
public offering the inclusion of such securities would interfere with the
successful marketing of the Purchased Shares or require the exclusion of any
portion of the Purchased Shares to be registered.

               10.2  Incidental Registration.  Each time the Company shall
                     -----------------------                              
determine to proceed with the actual preparation and filing of a registration
statement under the Securities Act in connection with the proposed offer and
sale for money of any of its securities by it or any of it security holders, the
Company will give written notice of its determination to Investor.  Upon written
request of Investor given within 30 days after receipt of any such notice from
the Company, the Company will, except as herein provided, cause all shares of
Purchased Shares for which Investor has so requested registration thereof, to be
included in such registration statement, all to the extent requisite to permit
the sale or other disposition by Investor; provided, however, that nothing
herein shall prevent the Company from, at any time, abandoning or delaying any
such registration initiated by it; provided further, however, that if the
Company determines not to proceed with a registration after the registration
statement has been filed with the Commission and the Company's decision not to
proceed is primarily based upon the anticipated public offering price of the
securities to be sold by the Company, the Company shall promptly complete the
registration for the benefit of Investor should Investor wish to proceed with a
public offering of its Purchased Shares provided Investor agrees to bear all
expenses in excess of $25,000 incurred by the Company as the result of such
registration after the Company has decided not to proceed.  If any registration
pursuant to this section shall be underwritten in whole or in part, the Company
may require that the Purchased Shares requested for inclusion pursuant to this
section be included in the underwriting on the same terms and conditions as the
securities otherwise being sold through the underwriters.  In the event that the
Purchased Shares requested for inclusion pursuant to this section would
constitute more than twenty-five percent (25%) of the total number of shares to
be included in a proposed underwritten public offering, and if in the good faith
judgment of the managing underwriter of such public offering the inclusion of
all of the Purchased Shares originally covered by a request for registration
would reduce the number of 

                                     -24-
<PAGE>
 
shares to be offered by the Company or interfere with the successful marketing
of the shares of stock offered by the Company, the number of shares of Purchased
Shares otherwise to be included in the underwritten public offering may be
reduced pro rata among all holders thereof requesting such registration;
provided, however, that after any such required reduction the Purchased Shares
to be included in such offering shall constitute at least twenty-five percent
(25%) of the total number of shares to be included in such offering. Those
shares of Purchase Shares which are thus excluded from the underwritten public
offering shall be withheld from the market by the holders thereof for a period,
not to exceed 60 days, which the managing underwriter reasonably determines is
necessary in order to effect the underwritten pubic offering.

               10.3  Registration Procedures.  If and whenever the Company is
                     -----------------------                                 
required by the provisions of section 10.1 or 10.2 to effect the registration of
any Purchased Shares under the Securities Act, the Company will:

               (a) prepare and file with the Commission a registration statement
     with respect to such securities, and use its best efforts to cause such
     registration statement to become and remain effective for such period as
     may be reasonably necessary to effect the sale of such securities, not to
     exceed six (6) months;

               (b) prepare and file with the Commission such amendments to such
     registration statement and supplements to the prospectus contained therein
     as may be necessary to keep such registration statement effective for such
     period as may be reasonably necessary to effect the sale of such
     securities, not to exceed six (6) months;

               (c) furnish to Investor, to the extent it is participating in
     such registration and to the underwriters of the securities being
     registered such reasonable number of copies of the registration statement,
     preliminary prospectus, final prospectus and such other documents as
     Investor and the underwriters may reasonably request in order to facilitate
     the public offering of such securities;

               (d) use its best efforts to register or qualify the securities
     covered by such registration statement under such state securities or blue
     sky laws of such jurisdictions as Investor may reasonably request within 20
     days following the original filing of such registration statement, except
     that the Company shall not for any purpose be required to execute a general
     consent to service of process or to qualify to do business as a foreign
     corporation in any jurisdiction wherein it is not so qualified;

               (e)  notify Investor promptly and confirm such advice in writing:

                                     -25-
<PAGE>
 
               (i)   when the registration statement, any pre-effective
     amendment, the prospectus or any prospectus supplement or post-effective
     amendment to the registration statement has been filed, and with respect to
     the registration statement or any post-effective amendment, when the same
     has become effective,  

               (ii)  of any request by the Commission for amendments or
     supplements to the registration statement or the prospectus or for
     additional information,

               (iii) of the receipt by the Company of any notification with
     respect to the suspension of the qualification of any Purchased Shares for
     sale under the securities or "Blue Sky" laws of any jurisdiction or the
     initiation or threat of any proceeding for such purpose, and

               (iv)  of the existence of any fact which results in the
     registration statement, the prospectus or any document incorporated therein
     by reference containing an untrue statement of material fact or omitting to
     state a material fact required to be stated therein or necessary to make
     any statement therein not misleading;

          (f)  prepare and file with the Commission, promptly upon the request
of Investor, any amendments or supplements to such registration statement or
prospectus which, in the opinion of counsel for Investor (and concurred in by
counsel for the Company), is required under the Securities Act or the rules and
regulations thereunder in connection with the distribution of the Purchased
Shares by Investor;

          (g)  prepare and promptly file with the Commission and promptly notify
Investor of the filing of such amendment or supplement to such registration
statement or prospectus as may be necessary to correct any statements or
omissions if, at the time when a prospectus relating to such securities is
required to be delivered under the Securities Act, any event shall have occurred
as the result of which any such prospectus or any other prospectus as then in
effect would include an untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein, in the light of the
circumstances in which they were made, not misleading;

          (h)  advise Investor, promptly after it shall receive no or obtain
knowledge thereof, of the issuance of any stop order by the Commission
suspending the effectiveness of such registration statement or the initiation or
threatening of any proceeding for the purpose and promptly use its best efforts
to prevent the issuance of any stop order or to obtain its withdrawal of such
stop order should be issued;
                                     -26-
<PAGE>
 
               (i)  not file any amendment or supplement to such registration
     statement or prospectus to which Investor shall have reasonably objected on
     the grounds that such amendment or supplement does not comply in all
     material respects with the requirements of the Securities Act or the rules
     and regulations thereunder, after having been furnished with a copy thereof
     at least five business days prior to the filing thereof, unless in the
     opinion of counsel for the Company the filing of such amendment or
     supplement is reasonably necessary to protect the Company from any
     liabilities under any applicable federal or state law and such filing will
     not violate applicable law; and

               (j) enter into such customary agreements and take all such other
     actions in connection therewith in order to expedite or facilitate the
     disposition of such Purchased Shares, whether or not an underwriting
     agreement is entered into and whether or not the Purchased Shares are to be
     sold in an underwritten offering.

               10.4  Expenses.  With respect to each inclusion of Purchased
                     --------                                              
Shares in a registration statement pursuant to section 10.2 (except as otherwise
provided in section 10.2 with respect to registrations terminated by the
Company), the Company shall bear the following fees, costs and expenses: all
registration, filing and NASD fees (or, if applicable, the fees and expenses
incurred in connection with the listing of the securities to be registered on
each securities exchange on which such securities are required to be listed),
printing expenses and disbursements of counsel and accountants for the Company,
fees and disbursements of counsel for the underwriter or underwriters of such
securities (if the Company and/or Investor (as a selling security holder) are
required to bear such fees and disbursements), all internal expenses, the
premiums and other costs of policies of insurance against liability arising out
of the pubic offering, if any, and all legal fees and disbursements and other
expenses of complying with the state securities or blue sky laws of any
jurisdictions in which the securities to be offered are to be registered or
qualified; provided, however, that nothing contained herein shall be deemed to
require the Company to consent to general service of process in any state in
order to qualify its securities for sale therein.  With respect to any
registration, including registrations pursuant to Form S-3, requested pursuant
to section 10.1 (except as otherwise provided in such section with respect to
registrations voluntarily terminated at the request of Investor and except with
respect to any underwriter's expense on any registration using Form S-3 that is
underwritten), the Company shall bear all fees, costs and expenses including,
but not limited to, those listed above.  Notwithstanding anything to the
contrary contained herein, fees and disbursements of counsel and accountants for
Investor along with any commissions and transfer taxes owing by Investor shall
be borne by Investor.

               10.5  Indemnification.  In the event that any Purchased Shares
                     ---------------                                           
are included in a registration statement under sections 10.1 or 10.2:

                                     -27-
<PAGE>
 
               (a) The Company will indemnify Investor and hold Investor
     harmless pursuant to the provisions of this article and will indemnify any
     underwriter (as defined in the Securities Act) for Investor and each
     person, if any, who controls Investor or such underwriter within the
     meaning of the Securities Act, from and against any and all losses, claims,
     damages, liabilities, costs and expenses (including, but not limited to all
     legal or other expenses reasonably incurred by it in connection with
     investigating or defending any loss, claim, damage, liability, cost and
     expense and any amounts paid in settlement of any litigation, commenced or
     threatened, if such settlement is effected with the prior written consent
     of the Company) to which Investor and/or any such underwriter or
     controlling person may become subject under the Securities Act or
     otherwise, insofar as such losses, claims, damages, liabilities, costs or
     expenses are caused by any untrue statement or alleged untrue statement of
     any material fact contained in such registration statement, any prospectus
     contained therein or any amendment or supplement thereto, or arise out of
     or are based upon the omission or alleged omission to state therein a
     material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances in which they were made,
     not misleading; provided, however, that the Company will not be liable to
     Investor to the extent that any such loss, claims, damage, liability, cost
     or expense arises out of or is based upon an untrue statement or alleged
     untrue statement or omission or alleged omission so made in conformity with
     information furnished by Investor.

               (b) Investor will indemnify and hold harmless the Company, any
     controlling person and any underwriter from and against any and all losses,
     claims, damages, liabilities, costs or expenses to which the Company or any
     controlling person and/or any underwriter may become subject under the
     Securities Act or otherwise, insofar as such losses, claims, damages,
     liabilities, costs or expenses are caused by any untrue, or alleged untrue
     statement of any material fact contained in such registration statement,
     any prospectus contained therein or any amendment or supplement thereto, or
     arise out of or are based upon the omission or the alleged omission to
     state therein a material fact required to be stated therein or necessary to
     make the statement therein, in light of the circumstances in which they
     were made, not misleading, in each case to the extent, but only to the
     extent, that such untrue statement or alleged untrue statement or omission
     or alleged omission was so made in reliance upon and in strict conformity
     with information furnished by Investor.

               (c)  Promptly after receipt by any indemnified party pursuant to
     the provisions of paragraph (a) or (b) of this section of notice of the
     commencement of any action involving the subject matter of the foregoing
     indemnity provisions, such indemnified party will, if a claim thereof is to
     be made against the indemnifying party pursuant to the provisions of said

                                     -28-
<PAGE>
 
     paragraph (a) or (b), promptly notify the indemnifying party of the
     commencement thereof; but the omission to so notify the indemnifying party
     will not relieve it from any liability which it may have to any indemnified
     party otherwise than hereunder.  In case such action is brought against any
     indemnified party and it notifies the indemnifying party of the
     commencement thereof, the indemnifying party shall have the right to
     participate in, and, to the extent that it may wish, jointly with any other
     indemnifying party similarly notified, to assume the defense thereof, with
     counsel satisfactory to such indemnified party; provided, however, if the
     defendants in any action include both the indemnified party and the
     indemnifying party and there is a conflict of interest which would prevent
     counsel for the indemnifying party from also representing the indemnifying
     party, the indemnified party or parties shall have the right to select
     separate counsel to participate in the defense of such action on behalf of
     such indemnified party or parties.  After notice from the indemnifying
     party to such indemnified party of its election so to assume the defence
     thereof, the indemnifying party will not be liable to such indemnified
     party pursuant to the provisions of said paragraph (a) or (b) for any legal
     or other expense subsequently incurred by such indemnified party in
     connection with the defense thereof other than reasonable costs of
     investigation, unless (i) the indemnified party shall have employed counsel
     in accordance with the proviso of the preceding sentence, (ii) the
     indemnifying party shall not have employed counsel satisfactory to the
     indemnified party to represent the indemnified party within a reasonable
     time   after the notice of the commencement of the action, or (iii) the
     indemnifying party has authorized the employment of counsel for the
     indemnified party at the expense of the indemnifying party.

               10.6  Registration Rights of Transferees.  The registration 
                     ----------------------------------                      
rights granted pursuant to this article 10 shall also be for the benefit of, and
enforceable by, any subsequent holder of Purchased Shares, whether or not any
express assignment of such rights to any such subsequent holder is made, so long
as such subsequent holder acquires at least twenty-five percent (25% ) of the
Purchased Shares then outstanding.

          11.  Default.
               ------- 

               11.1  Events of Default.  Each of the following events shall be
                     -----------------                                       
 an event of default (an "Event of Default") for purposes of the Agreement:

               (a) if the Company shall default in any material respect in the
     due and punctual performance of any covenant or agreement in any note,
     bond, indenture, loan agreement, note agreement, mortgage, security
     agreement or other instrument evidencing or related to bank indebtedness of
     the Company in excess of $400,000, and such default shall continue for more

                                     -29-
<PAGE>
 
     than the period of notice and/or grace, if any, therein specified and shall
     not have been waived; or

               (b) (i) if any representation or warranty made by or on behalf of
     the Company in the Agreement or in any certificate, report or other
     instrument delivered under or pursuant to any term hereof shall prove to
     have been untrue or incorrect in any material respect as of the date of the
     Agreement, or (ii) if any report, certificate, financial statement or
     financial schedule or other instrument prepared or purported to be prepared
     by the Company or any officer of the Company hereafter furnished or
     delivered under or pursuant to the Agreement shall prove to be untrue or
     incorrect in any material respect as of the date it was made, furnished or
     delivered; or

               (c) if the Company defaults in the due and punctual performance
     or observance of any covenant contained in the Agreement, and such default
     continue for a period of 15 days after written notice thereof to the
     Company by Investor; provided, however, that an Event of Default shall not
     be deemed to have occurred if, at the end of such 15-day, the Company is
     diligently attempting to cure such default and the existence of such
     default is not materially adversely affecting the business or financial
     condition of the Company; or

are only transferable pursuant to (a) a public offering registered under the
Securities Act, (b) Rule 144 or Rule 144A under the Securities Act (or any
similar rule then in effect) if such rules are or become available, or (c)

endorsed with the following legends:

          "The shares represented by this certificate may not be transferred
          without (i) the opinion of counsel satisfactory to this corporation
          that such transfer may lawfully be made without registration under the
          Securities Act of 1933, as amended and all applicable state securities
          laws or (ii) such registration."

          "The securities represented by this certificate are subject to certain
          transfer and co-sale rights set forth in certain agreements, dated
          September 27, 1993, between the registered owner of such securities
          and certain other persons, and may not be sold, transferred or
          otherwise disposed of except in compliance with the terms of such
          agreements, a copy of which is available for inspection in the
          principal office of the issuer of such securities."

Upon the conversion of any Shares, unless the Company receives an opinion of
counsel satisfactory to the Company to the effect that a transfer of the
Conversion 

                                     -31-
<PAGE>
 
Shares may be made without registration or further restriction or transfer, or
unless such Conversion Shares are being disposed of pursuant to a registration
under the Securities Act, the same legend shall be endorsed on the certificate
evidencing such Conversion Shares.

               12.3  Removal of Legend.  Other than with respect to the removal
                     -----------------                                         
of any legend evidencing transfer restrictions on Shares arising out of the Co-
Sale or Shareholder Agreements (which removal shall be governed by the terms of
such Agreements), any legend endorsed on a certificate evidencing a security
pursuant to section 12.2 hereof shall be removed, and the Company shall issue a
certificate without such legend to Investor (or its nominee, designee or
transferee, as the case may be), if such security is being disposed of pursuant
to a registration under the Securities Act or pursuant to Rule 144, Rule 144A or
any rule, regulation or other exemption then in effect or if Investor (or its
designee or proposed transferee) provides the Company with an opinion of counsel
satisfactory to the Company to the effect that a transfer of such security may
be made pursuant to Rule 144, Rule 144A or any rule, regulation or other
exemption then in effect, without registration.  In addition, if Investor
delivers to the Company an opinion of such counsel to the effect that no
subsequent transfer of such security will require registration under the
Securities Act, the Company will promptly upon such contemplated transfer
deliver new certificates evidencing such security that do not bear the legend
set forth in section 12.2.

          13.  Investor Covenant Not to Buy Shares.  Other than with respect to
               -----------------------------------                             
share purchases which Investor may elect to make pursuant to the Shareholder
Agreement, Investor covenants that it shall neither buy nor solicit offers to
sell any shares of capital stock or any purchase rights to acquire any shares of
capital stock of the Company, from any person, partnership or entity which is
currently a shareholder of the Company on the date of this Agreement until the
earlier to occur of the events set forth in section 14(i) or (ii) below.

          14.  Termination of Covenants.  The obligations of the Company under
               ------------------------                                       
Articles 7 and 8 of the Agreement and the right to designate a majority of the
Board of Directors of the Company under section 11.2 of the Agreement,
notwithstanding any provisions hereof apparently to the contrary, shall
terminate and shall be of no further force or effect on the earliest to occur of
