                                  THE COMPANY
 
INTRODUCTION
 
     IOMED, Inc. (the "Company") develops, manufactures and commercializes
controllable drug delivery systems using iontophoretic technology. Iontophoresis
is a non-invasive method of enhancing and controlling the transport of
water-soluble ionic drugs into and through the skin using a low level electrical
current. The Company's proprietary iontophoretic drug delivery systems allow
rapid onset and cessation of therapeutic action, as well as programmable dose
control. The systems enable caregivers to monitor and control the onset of drug
effectiveness and maintain, reduce or cease drug administration once a desired
therapeutic effect is observed. Additionally, the Company is developing systems
designed to permit patient control and selfadministration. The programming
feature also enables caregivers to customize dosing patterns to meet each
patient's specific needs. The flexibility of the Company's proprietary systems
provides therapeutic control not possible with many alternative drug delivery
methods, including oral tablets and capsules, injections, inhalants, and passive
transdermal patches. The Company's systems may also increase bioavailability,
safety and patient comfort.
 
BUSINESS STRATEGY
 
     The Company's primary business goal is to establish its proprietary
iontophoretic drug delivery systems as a cost effective preferred means of
delivering a wide range of drugs. The Company's strategy for achieving this goal
includes (i) pursuing product development of drug delivery systems for
off-patent drugs with known safety and efficacy; (ii) entering into
collaborative relationships with pharmaceutical companies for the delivery of
new chemical entities and proprietary drugs; (iii) broadening the market
penetration and potential applications of the Company's existing delivery
systems; (iv) enhancing the Company's technology platform through internal
research and development; (v) pursuing new technology through in-licensing and
acquisitions; and (vi) retaining control of the manufacturing revenue stream.
 
COMPANY PRODUCTS
 
     The Company currently markets two products, an iontophoretic system used to
deliver dexamethasone sodium phosphate ("Dexamethasone"), a corticosteriod used
in the treatment of acute local inflammation, and an iontophoretic system used
to deliver Iontocaine, a proprietary drug used for local dermal anesthesia. The
iontophoretic drug delivery systems the Company currently markets are comprised
of a reusable programmable dose controller which is used to direct the
electrical current to control drug dosing and a pair of proprietary disposable
electrodes, one containing the drug and one serving as a grounding electrode to
complete the electrical circuit through the skin. The drug delivery electrode
may be applied to the patient's skin at a local treatment site (such as for
joint or tendon soreness or to induce local dermal anesthesia), or at any
suitable site on the body for systemic drug delivery. When an electrical current
with the same positive or negative electric charge as the drug is applied to the
drug electrode, the drug is repelled from the electrode and into and through the
skin.
 
     Dexamethasone. The Company's acute local inflammation product is a system
used principally by physical therapists and professional athletic trainers for
the delivery of Dexamethasone. Since it was
 
                                        3
<PAGE>   5
 
introduced in 1979, the Company's product has been used in over 10 million
patient applications for the treatment of acute inflammatory conditions such as
tendonitis (e.g. tennis elbow, golfers elbow and achilles tendonitis), bursitis
and carpal tunnel syndrome. More than 8 million of these applications have
occurred since 1990, when the Company introduced its present family of gel
electrodes for use with its microprocessor controlled dose controller. The
product is currently marketed to the physical therapy market as a device, under
a 510(k) pre-market notification by the United States Food and Drug
Administration ("FDA"), for use in connection with delivering ions of soluble
salts or other drugs. Recently, the FDA determined that all future iontophoretic
drug delivery systems will be required to go through the New Drug Application
process with the specific drug that is to be delivered. In order to address the
new regulatory framework and to broaden the clinical basis for the treatment of
acute local inflammation using the Company's iontophoretic delivery system for
Dexamethasone, the Company has filed an Investigational New Drug application
with the FDA and has initiated clinical studies to establish formally the safety
and efficacy of its drug delivery system for Dexamethasone. If the clinical
trials are successful and the Company receives regulatory approval, the Company
believes it will be able to actively promote the iontophoretic delivery of
Dexamethasone to general and family practice physicians, orthopedists,
neurologists and sports and industrial medicine clinics. The Company believes
the ability to promote iontophoresis with Dexamethasone will enhance its ability
to establish its delivery system for Dexamethasone as a primary treatment option
for acute local inflammatory conditions.
 
   
     Iontocaine. The Company's iontophoretic delivery system was approved by the
FDA in January 1996 for use in inducing local dermal anesthesia, and the Company
began marketing the product in early 1997. Iontocaine is the first drug with
labeling specifically for iontophoretic delivery. In addition, Iontocaine is
approved for use only with the Company's drug delivery systems. The Iontocaine
product provides needle-free, long lasting local dermal anesthesia up to six
times more rapidly and up to three times deeper than can be achieved using
topical anesthetic creams. The Company is initially marketing its Iontocaine
delivery system under the name Numby Stuff to pediatric hospitals in the United
States for use in connection with inducing local dermal anesthesia prior to
pediatric intravenous starts, blood draws, lumbar punctures and other similar
invasive procedures. The Company was recently granted the Alliance of Children's
Hospital's ("ACH") Seal of Acceptance in connection with the promotion of Numby
Stuff. The Seal of Acceptance was granted by ACH in recognition of the
significant therapeutic benefits ACH believes Numby Stuff offers in the practice
of pediatric medicine. In order to use the Seal of Acceptance to promote Numby
Stuff, the Company was required to make royalty payments to ACH. The Company
satisfied ACH's royalty requirement by issuing ACH warrants to acquire 44,791
Common Shares. In addition, in connection with obtaining the right to use the
ACH Seal of Acceptance, the Company sold an ACH affiliate 37,202 Common Shares.
The Company plans to extend its marketing efforts for Iontocaine to include
pediatric clinics, non-pediatric hospitals, and office based physician practices
for use in connection with numerous therapeutic applications, including blood
draws and minor dermatological procedures. The Company is also evaluating the
use of Iontocaine in connection with gynecological procedures requiring dermal
or mucosal anesthesia. The use of Iontocaine for mucosal applications will
require additional FDA approval.
    
 
     Many pharmaceutical compounds, including peptides and oligonucleotides,
have physical and chemical properties consistent with delivery by iontophoresis.
Therefore, the Company believes its technology may be applicable to a number of
other compounds and therapeutic applications. The Company is also independently
developing a number of iontophoretic drug delivery systems for other
indications, including conscious sedation, tocolysis (the remission of pre-term
labor), and postoperative and chronic pain control.
 
COLLABORATIVE RELATIONSHIPS
 
     Novartis. In July 1995, the Company entered into a research and development
agreement with Ciba Pharmaceuticals Corporation, a predecessor to Novartis
Pharmaceuticals Corporation ("Novartis"), an affiliate of Novartis Pharma, A.G.,
the international pharmaceutical company formed as a result of the merger of
Ciba-Geigy Corporation and Sandoz Corporation in 1997. The collaboration was
formed to evaluate the development of iontophoretic drug delivery systems for a
number of Novartis compounds for use in several therapeutic applications. The
joint effort is currently directed toward the development of a delivery system
for
 
                                        4
<PAGE>   6
 
a compound to treat osteoporosis. The Company believes this system could enter
Phase I clinical trials during 1998.
 
     In connection with the collaboration, Novartis purchased a 20% equity
interest in Dermion, Inc. ("Dermion"), a subsidiary of the Company that conducts
most of its research and development activities. The Company, Dermion and
Novartis amended the terms of their collaborative arrangement. Under the terms
of the amendment, effective November 1, 1997, Novartis exchanged its interest in
Dermion for 238,541 Common Shares of the Company and warrants to acquire under
certain conditions and through November 1, 2002, an additional 18,750 Common
Shares at an exercise price of $21.60 per share. As a result, Dermion became a
wholly-owned subsidiary of the Company. Pursuant to the agreements, Novartis is
required to pay for research costs under the program and to make milestone
payments upon the successful completion of certain later stage development
objectives. In addition, the Company granted Novartis a perpetual,
non-exclusive, royalty bearing license to the Company's iontophoretic technology
as well as certain rights with respect to future technology developed or
acquired by the Company.
 
     Elan. In March 1997, the Company entered into agreements with Elan
Corporation, plc and certain of its affiliates (collectively, "Elan"), an
international developer and manufacturer of advanced drug delivery technologies.
The agreements provide the Company with exclusive, worldwide licenses to certain
of Elan's iontophoretic drug delivery technology, including over 250 issued and
47 pending United States and foreign patents, as well as a significant body of
know-how and clinical study results. The Company believes the Elan technology
significantly expands its iontophoretic technology platform, enhances its
competitive position and better positions the Company to shorten the development
horizon of its iontophoretic drug delivery systems, including the miniaturized,
integrated, wearable systems currently under development by the Company. The
Company acquired the Elan technology by issuing two promissory notes, a $10.0
million note and a $5.0 million note (the "Elan Notes"). Under the agreement
with Elan, Elan will purchase directly from the Company, in private placement
transactions which will be completed concurrently with the closing of the
Offering, 833,333 Common Shares (subject to adjustment under certain
circumstances) for approximately $10.2 million and approximately $5.1 million of
Common Shares at a price per share equal to the initial public offering price
hereunder (425,000 shares assuming an initial public offering price of $12.00
per share) (collectively, the "Elan Shares"). Simultaneously with such
purchases, the Company will repay the Elan Notes, including interest thereon.
 
     The Company was incorporated in Utah in 1974 as Motion Control, Inc. In
1987, the Company merged with JMW Acquisition Corporation, and the name of the
merged entity was changed to IOMED, Inc. All references to the Company include
the Company's predecessor entities, as well as Dermion. The Company's principal
executive offices are located at 3385 West 1820 South, Salt Lake City, Utah
84104, and its telephone number is (801) 975-1191.

                                  RISK FACTORS
 
     IN ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS,
PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER THE FOLLOWING FACTORS BEFORE
PURCHASING THE COMMON SHARES OFFERED HEREBY. PROSPECTIVE INVESTORS ARE CAUTIONED
THAT THE STATEMENTS IN THIS SECTION THAT ARE NOT DESCRIPTIONS OF HISTORICAL
FACTS MAY BE FORWARD-LOOKING STATEMENTS THAT ARE SUBJECT TO RISKS AND
UNCERTAINTIES. ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE CURRENTLY
ANTICIPATED DUE TO A NUMBER OF FACTORS, INCLUDING THOSE IDENTIFIED IN THIS
SECTION, "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS," "BUSINESS" AND ELSEWHERE IN THIS PROSPECTUS.
 
     CONTINUING OPERATING LOSSES; UNCERTAINTY OF FUTURE PROFITABILITY. The
Company earned modest profits in each of the fiscal years 1988 through 1990, and
experienced losses from operations in fiscal years 1991 through 1995, due
primarily to increased investment in product development, clinical studies, and
increased sales and marketing activity. The Company again earned a profit from
operations in fiscal year 1996, but experienced a substantial loss from
operations in fiscal year 1997 primarily due to the write-off of purchased
in-process research and development. The Company had an accumulated deficit of
$21.6 million as of September 30, 1997. The Company intends to substantially
expand its research and development and marketing efforts in the near future
and, therefore, does not anticipate being profitable in the near term. The
Company's ability to achieve and sustain profitability will depend on its
ability to achieve market acceptance, and successfully expand sales of its
existing products, as well as successfully complete the development of, receive
regulatory approvals for, and successfully manufacture and market, its products
under development, as to which there can be no assurance. In addition, the
Company may be required to give away or substantially discount its current or
future products in order to stimulate demand, either of which events could have
a material adverse effect on the Company's business, financial condition and
results of operations. The success of the Company's current products and
products under development may also depend on the timing of new product
introductions by the Company relative to its competitors and other factors. As a
result of the foregoing, no assurance can be given that the Company will become
profitable on a sustained basis, if at all. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
     UNCERTAINTY OF MARKET ACCEPTANCE AND LIMITED MARKET PENETRATION. The
Company has generated only limited revenues, primarily from sales to physical
therapists of its drug delivery system for dexamethasone sodium phosphate
("Dexamethasone") for the treatment of acute local inflammation. The Company
began marketing Iontocaine, its proprietary local dermal anesthetic product, in
January 1997 and has generated only limited revenues from that product to date.
For the Company to be successful, its products will need to achieve broad market
acceptance by the medical profession. The Company's products use a method of
active transdermal drug delivery which, to date, has not gained significant
market penetration, and no assurance can be given that the Company's current or
future products will ever achieve broad market acceptance. Medical professionals
will not use or prescribe the Company's products unless they determine they are
a preferable alternative to products currently available on the market. The
Company believes recommendations and endorsements by influential medical
professionals may be essential for market acceptance of its products, but there
can be no assurance the Company will be able to obtain any such recommendations
or endorsements. In addition, the adoption of new pharmaceutical products is
greatly influenced by health care administrators, inclusion in hospital
formularies and reimbursement by third party payors. No assurance can be given
that health care administrators, hospitals or third party payors will accept the
Company's products on a large scale or on a timely basis, if at all, or that the
Company will be able to obtain labeling for its products which facilitate their
market acceptance or use. In addition, unanticipated side effects or unfavorable
publicity concerning any of the Company's products, or any other product
incorporating technology similar to that used in the Company's products, could
have an adverse effect on the Company's ability to commercialize its products or
achieve market acceptance. The occurrence of any such event could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Products and Products Under Development"
and "Business -- Sales and Distribution."
 
     UNCERTAINTIES RELATED TO PRODUCT DEVELOPMENT; CLINICAL TRIALS. Two of the
primary components of the Company's business strategy are to develop and
commercialize iontophoretic drug delivery systems for new and existing drugs and
to develop additional applications for its existing products. The Company will
be
 
                                        8
<PAGE>   10
 
required to undertake time-consuming and costly development activities and seek
regulatory approval for these new products and applications. Product revenues
may not be realized from the sale of any such products for several years, if at
all. The Company can give no assurance that its product development efforts,
either alone or in collaboration with other parties, will ever be successfully
completed, that it can obtain required regulatory approvals of its products,
that products under development can be manufactured at acceptable cost or with
appropriate quality, or that its products can be marketed successfully.
 
     Before seeking regulatory approval for the commercial sale of its products,
the Company must demonstrate through preclinical studies and clinical trials
that those products are safe and effective for use in the target indications.
The rate of completion of the Company's clinical trials is dependent upon, among
other things, the rate of patient enrollment. Patient enrollment is a function
of many factors, including the size of the patient population, the nature of the
protocol, the proximity of patients to clinical sites and the eligibility
criteria for the study. There can be no assurance the Company will be able to
obtain the patient enrollment it needs to complete its clinical trials in a
timely manner, if at all. The results the Company obtains from preclinical
studies and early clinical trials may not be indicative of results it will
obtain in large-scale testing, and there can be no assurance the Company's
clinical trials will demonstrate sufficient safety and efficacy for it to obtain
the requisite regulatory approvals, or that those clinical trials will result in
additional marketable products. Clinical trials are also often conducted with
patients having advanced stages of disease. During the course of treatment,
these patients can die, suffer undesired side effects or suffer other adverse
medical effects for reasons that may not be related to the pharmaceutical agent
or drug delivery system being tested, any of which can have an adverse effect on
clinical trial results. A number of companies in the pharmaceutical industry
have suffered significant setbacks in advanced clinical trials, even after
promising results in earlier trials, as a result of such adverse effects. The
use of any product the Company develops may produce undesirable side effects
that could result in the interruption, delay or suspension of clinical trials,
or the failure to obtain United States Food and Drug Administration ("FDA") or
other regulatory approval for targeted indications. If the Company's products
under development are not shown to be safe and effective in clinical trials, the
resulting delays in developing other compounds and conducting related
preclinical testing and clinical trials, as well as the need for additional
financing to complete such testing and trials, could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business -- Products and Products Under Development,"
"Business -- Manufacturing" and "Business -- Government Regulation."
 
     RELIANCE ON COLLABORATIVE PARTNERS. The Company's strategy is to enter into
arrangements with corporate partners, licensors, licensees and other parties for
the development, clinical testing, manufacture, marketing or commercialization
of certain of its products or products in development. The Company currently has
a collaborative arrangement with Novartis Pharmaceuticals Corporation
("Novartis"), an affiliate of Novartis Pharma A.G., the international
pharmaceutical company formed as a result of the merger of Ciba-Geigy
Corporation and Sandoz Corporation in 1997. The collaboration was formed to
evaluate the potential for effective delivery by iontophoresis of several
Novartis compounds covering a range of therapeutic applications.
 
     Collaborative partners in the development of medical drugs and devices
generally have the right to pursue parallel development of other products which
may compete with the products of the other collaborative partner, and to
terminate their agreements without significant penalty under certain conditions.
Any parallel development by a collaborative partner of the Company of alternate
drug delivery systems, development by a partner rather than by the Company of
components of the delivery system, preclusion from entering into competitive
arrangements, failure to obtain timely regulatory approvals, premature
termination of an agreement, or a decision by a collaborative partner not to
devote sufficient resources to the development and commercialization of the
Company's products could have a material adverse effect on the Company's
business, financial condition or results of operations.
 
     The Company's success may depend upon, among other things, the skills,
experience and efforts of the Company's collaborative partners' employees who
are responsible for the collaborative project, such partners' commitment to the
arrangement, and the financial condition of such partners, all of which are
beyond the control of the Company. If one or more of the Company's collaborative
partners defaulted on their obligations
 
                                        9
<PAGE>   11
 
under their collaborative agreements, the Company could be forced to engage in
litigation to enforce those obligations (which could be time consuming and
costly) or seek to enter into agreements with other parties upon similar terms.
There can be no assurance the Company will be able to enforce the terms of its
collaborative arrangements through litigation, and there can be no assurance
that, if forced to terminate its current collaborative arrangements, the Company
would be able to enter into other contractual arrangements with other parties on
terms which would not be materially different from the terms of its current
collaborative arrangements.
 
     A significant portion of the Company's research and development resources
has been devoted to its contractual research and development efforts with
Novartis. Since 1995, Novartis has funded a substantial portion of the total
research and development costs of the Company. The amount and timing of
resources to be devoted by Novartis in accomplishing the objectives of its
collaborative development effort with the Company are not within the control of
the Company, and there can be no assurance that Novartis will continue its
collaborative development with the Company beyond the current term of the
agreement, which has been extended through December 31, 1998. Either party can
terminate the collaboration upon six months prior written notice. There also can
be no assurance that Novartis will perform its obligations as expected or that
it will not pursue other existing or alternative technologies in preference to
products it is developing with the Company or that it will not terminate the
collaboration prior to its expiration. In addition, in connection with this
collaboration, the Company granted Novartis a perpetual, non-exclusive, royalty
bearing license to the Company's iontophoretic technology which will survive the
termination of the collaboration. The license to Novartis, though non-exclusive,
may make it more difficult for the Company to enter into new collaborations,
which could have a material adverse effect on the Company. Further, other than
in collaboration with Novartis, the Company has agreed that during the term of
the agreement and for a period of up to two years thereafter, the Company will
not develop any product in certain Novartis fields, as defined in the agreement,
without Novartis' consent. There can be no assurance that Novartis will not
terminate its agreement with the Company and independently develop products
using the licensed technology, including products which may compete directly
with those currently marketed or under development by the Company. If Novartis
terminates its agreement with the Company, the Company's business, financial
condition and results of operations could be materially and adversely affected.
 
     In connection with the establishment of the Novartis collaboration, the
Company formed Dermion, Inc. ("Dermion") to perform the Company's research and
development activities and Novartis acquired a 20% equity interest in Dermion.
The Company, Dermion and Novartis recently amended the terms of their
relationships. Under these amendments (the "1997 Amendments"), effective
November 1, 1997, Novartis exchanged its 20% equity interest in Dermion for
238,541 Common Shares and warrants to acquire up to an additional 18,750 Common
Shares at an exercise price of $21.60 per share. Novartis can currently exercise
one-third of the warrants, and its right to exercise the remaining warrants will
vest, as to an additional one-third in each instance, at the time it agrees, if
ever, to provide research and development funding under the parties' agreements
for each of 1999 and 2000. In addition, under the agreement with Novartis, the
Company is restricted in its ability to sell or otherwise dispose of the assets
or control of Dermion through March 1998, and Novartis has a right of first
offer to acquire either the Company's interest in Dermion or Dermion's business
and assets in the event of any proposed change of control of Dermion during the
remainder of the term of the Novartis research and development agreement and for
one year thereafter.
 
     The Company has also agreed that, during the term of the agreement with
Novartis and for a period of five years thereafter, the Company will negotiate
in good faith to license to Novartis rights to any iontophoretic drug delivery
technologies developed or acquired by the Company but which are not covered
under the existing license agreements (the "Second Generation Technology").
Further the Company has agreed to negotiate such additional licenses prior to
entering into any agreement to license or otherwise transfer any rights to such
Second Generation Technology to a third party. Under the 1997 Amendments, the
parties agreed to treat the technology acquired by the Company from Elan
Corporation, plc and its affiliates ("Elan") as Second Generation Technology.
Accordingly, the Company intends to negotiate with Novartis to license such
technology to Novartis prior to initiating efforts to negotiate any rights to
such technology with any third party. See "Business -- Collaborative
Relationships and Licenses."
 
                                       10
<PAGE>   12
 
     Although the Company anticipates it will enter into additional
collaborative arrangements with other parties in the future, there can be no
assurance the Company will be able to negotiate any such additional
collaborative arrangements on terms which are acceptable to the Company, if at
all. In addition, the technology license and rights to future licenses granted
to Novartis may make it more difficult for the Company to find collaborative
partners for its product development programs. To the extent the Company chooses
not, or is not able, to establish such collaborations, it could experience
significantly increased business risk and capital requirements in the
development, clinical testing, manufacturing, marketing and commercialization of
its products. The Company could also encounter significant delays in introducing
products into markets or find that the development, manufacture or sale of
proposed products in such markets is adversely affected by the absence of those
collaborative arrangements.
 
     Under an agreement with a prior collaborative partner, Laboratoires
Fournier S.C.A. ("Laboratoires Fournier"), the Company has agreed, among other
things, not to pursue the development of a fentanyl-based iontophoretic drug
delivery system for chronic pain or sedation, or a hydromorphone-based
iontophoretic drug delivery system for the treatment of acute post-operative
pain, until the second quarter of calendar year 1998. See "Business -- Products
and Products Under Development."
 
     INTENSE COMPETITION AND RAPID TECHNOLOGICAL CHANGE. The drug delivery,
pharmaceutical and biotechnology industries are highly competitive and rapidly
evolving, with significant developments expected to continue at a rapid pace.
The first pharmaceutical product to reach the market in a therapeutic area or
using a certain drug delivery technology generally obtains and maintains a
significant market share relative to later entrants to the market. The Company's
success will depend on its ability to maintain a competitive position and
develop new products and technologies for efficient and cost effective drug
delivery. The Company's products will compete with other formulations of drugs
and with other drug delivery systems, including oral dosage forms, infusions,
injections, inhalants, and transmucosal, transnasal and transdermal products.
There can be no assurance any of the Company's products will have advantages
that will be significant enough to cause medical professionals to prefer or even
use them. New drugs or further development of alternative drug delivery methods
may provide greater therapeutic benefits for a specific drug or indication, or
may offer comparable performance at lower cost, than that offered by the
Company's iontophoretic drug delivery systems, which could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
     Many competitors, including public and private corporations, academic
institutions, governmental agencies and other public and private research
organizations, are involved in the development of drug delivery systems,
including the development of competing iontophoretic, similar
electrotransport-related or other drug delivery technologies. Many of these
competitors have substantially greater financial, technical, research and other
resources, are more experienced in research and development, manufacturing,
pre-clinical and clinical testing, and obtaining regulatory approvals, and are
larger, more established and have substantially larger marketing and service
organizations than the Company. In addition, these competitors may offer broader
product lines than the Company, have greater name recognition than the Company,
and offer discounts as a competitive tactic. Accordingly, the Company's
competitors may succeed in developing competing technologies, and obtaining FDA
approval or gaining market share for products, more rapidly than the Company.
Many of these competitors currently have drug delivery products that are
approved or in development. There can be no assurance the Company's competitors
will not succeed in developing or marketing products that are more effective or
commercially attractive than the Company's current or future products, or that
would render the Company's products obsolete or noncompetitive. There can also
be no assurance the Company will have the financial resources, technical or
management expertise or manufacturing or support capability to compete in the
future. See "Business -- Competition."
 
     The Company has licensed certain rights to its iontophoretic drug delivery
technologies to other parties, including Alza Corporation ("Alza"), Laboratoires
Fournier and Novartis, that may become or are direct competitors of the Company.
These companies could compete with the Company for contracts with the Company's
collaborative partners and could also develop iontophoretic drug delivery
systems that will compete directly with many of those currently marketed or
being developed by the Company. See "Business -- Collaborative Relationships and
Licenses."

     RELIANCE ON THIRD PARTY DISTRIBUTION; LIMITED SALES AND MARKETING
EXPERTISE. The Company presently markets its drug delivery systems for the
treatment of acute local inflammation primarily to physical therapists through a
nationwide system of dealers. The Company intends to market its local dermal
anesthesia products in the United States hospital market through sales personnel
who work directly for the Company, and anticipates that it will also use a third
party or collaborative partner to market its current and future products. See
"Business -- Sales and Distribution."
 
     The majority of the dealers the Company uses in the distribution of its
drug delivery systems for acute local inflammation are principally involved in
the distribution of electrotherapy equipment and other rehabilitation related
products to physical therapists and related physician specialists. The Company's
product does not represent a primary source of revenue for many of those
dealers. As a result, there can be no assurance those dealers will invest
adequate resources in the sale and promotion of the Company's products, sell
other products developed by the Company or even continue to sell the Company's
products.
 
     In cases where the Company intends to market its products using direct
sales personnel, such as with its drug delivery system for the inducement of
local dermal anesthesia, it will need to hire, train and supervise those
personnel. The Company has limited experience in marketing and sales, and only
recently began to recruit a marketing staff and sales force. The Company will
need to expend additional funds and management resources to assemble, train and
oversee a marketing and sales staff. There can be no assurance the Company can
successfully recruit, hire or retain personnel, nor can there can be any
assurance the Company will be able to maintain its relationships with the
marketing, sales and distribution resources it currently employs. There can also
be no assurance that the cost of establishing and maintaining a sales and
marketing staff will be justifiable in light of product revenues. If the
Company's marketing resources fail to perform in accordance with the Company's
expectations, the Company may be required to obtain or develop alternate
marketing, sales and distribution capabilities or seek other methods of
distributing its products. There can be no assurance the Company would be able
to do so or that the Company's sales and marketing efforts will be successful.
See "Business -- Sales and Distribution."
 
     DEPENDENCE ON PATENTS AND PROPRIETARY TECHNOLOGY. The Company's ability to
commercialize many of the products it has under development will depend, in
part, on its or its licensors' ability, both in the United States and in other
countries, to obtain patents, enforce those patents, preserve trade secrets and
operate without infringing on the proprietary rights of third parties. As of
October 1, 1997, the Company owned or had rights to 60 issued United States
patents, 15 pending United States patents, 245 issued foreign patents and 47
pending foreign patents.
 
     The patent positions of drug delivery, pharmaceutical and biotechnology
companies are highly uncertain and involve complex legal and factual questions.
There can be no assurance the patents currently owned and licensed by the
Company, or any future patents, will prevent other companies from developing
similar or therapeutically equivalent products, or that other companies will not
be issued patents that may prevent the sale of Company products or require
licensing and the payment of significant fees or royalties by the Company.
Furthermore, there can be no assurance any of the Company's products or methods
will be patentable, will not infringe upon the patents of third parties, or that
the Company's patents or future patents will give the Company an exclusive
position in the subject matter claimed by those patents. The Company may be
unable to avoid infringement of third party patents and may have to obtain
licenses, defend infringement actions or challenge the validity of those patents
in court. There can be no assurance a license will be available to the Company,
if at all, on terms and conditions acceptable to the Company, or that the
Company will prevail in any patent litigation. Patent litigation is costly and
time consuming, and there can be no assurance the Company will have or will
devote sufficient resources to pursue such litigation. If the Company does not
obtain a license under such patents, is found liable for infringement or is not
able to have such patents declared invalid, the Company may be liable for
significant monetary damages, may encounter significant delays in bringing
products to market or may be precluded from participating in the manufacture,
use, or sale of products or methods of treatment protected by such patents.
There can be no assurance the pending patent applications licensed to or owned
by the Company will result in issued patents, patent protection will be secured
for any particular technology, any patents that have been or may be issued to
the Company or its
 
                                       12
<PAGE>   14
 
licensors will be valid or enforceable or that the Company's patents will
provide meaningful protection to the Company.
 
     The Company also relies on trade secrets and other unpatented proprietary
information in its product development activities. To the extent the Company
relies on confidential information to maintain its competitive position, there
can be no assurance other parties may not independently develop the same or
similar information. The Company seeks to protect trade secrets and proprietary
knowledge in part through confidentiality agreements with its employees,
consultants, advisors and collaborators. These agreements may not effectively
prevent disclosure of the Company's confidential information and may not provide
the Company with an adequate remedy in the event of unauthorized disclosure of
such information. If the Company's employees, scientific consultants or
collaborators develop inventions or processes independently that may be
applicable to the Company's products under development, disputes may arise about
ownership of proprietary rights to those inventions and processes. Those
inventions and processes will not necessarily become the Company's property, but
may remain the property of those persons or their employers. Protracted and
costly litigation could be necessary to enforce and determine the scope of the
Company's proprietary rights. The Company's failure to obtain or maintain patent
and trade secret protection, for any reason, could have a material adverse
effect on the Company's business, financial position and results of operations.
 
     The Company may engage in collaborations, sponsored research agreements,
and other arrangements with academic researchers and institutions that have
received or may receive funding from United States government agencies. As a
result of these arrangements, the United States government or other parties may
have rights in certain inventions developed during the course of the performance
of such collaborations and agreements as required by law or such agreements.
Several legislative bills affecting patent rights have been introduced in the
United States Congress. These bills address various aspects of patent law,
including publication, patent term, re-examination, subject matter and
enforceability. It is not certain whether any of these bills will be enacted
into law or what form such new laws may take. Accordingly, the effect of such
potential legislative changes on the Company's intellectual property is
uncertain. See "Business -- Patents and Proprietary Rights."
 
     In August 1993, the United States Patent and Trademark Office ("PTO")
issued a patent to Alza covering the iontophoretic delivery of fentanyl. A
similar patent application in Europe has thus far been rejected, although the
Company believes Alza has appealed that rejection. The United States patent was
the subject of a reexamination by the PTO and all of the substantive claims
within the patent were also rejected, but Alza has appealed that rejection to
the United States Board of Patent Appeals and Interferences. There can be no
assurance Alza will not be successful in one or both of its appeals. Therefore,
if the Company develops a drug delivery system for fentanyl and if Alza is
successful in its appeal, the Company would be required to obtain a license from
Alza to market any iontophoretic drug delivery system it develops for fentanyl
in the United States. There can be no assurance such a license would be
available on terms acceptable to the Company, if at all. If the Company cannot
obtain such license, the Company will be required to discontinue its product
development programs using fentanyl. See "Business -- Products and Products
Under Development."
 
     NEED TO MANAGE EXPANDING OPERATIONS. If the Company is successful in
achieving market acceptance of its products, it will be required to expand its
operations, particularly in the areas of research and development, sales and
marketing and manufacturing. As the Company expands its operations in these
areas, those expansions will likely result in new and increased responsibilities
for management personnel and place significant strain on the Company's
management, operating and financial systems and other resources. To accommodate
any such growth and compete effectively, the Company will be required to
implement improved information systems, procedures and controls, and to expand,
train, motivate and manage its work force. The Company's future success will
depend to a significant extent on the ability of its current and future
management personnel to operate effectively both independently and as a group.
There can be no assurance the Company's personnel, systems, procedures and
controls will be adequate to support the Company's future operations.
 
                                       13

     FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FUNDING. The further
development and commercialization of the Company's products and technology will
require a commitment of substantial funds to conduct research and development
activities, including preclinical and clinical studies, to expand distribution
and hire additional sales and marketing personnel and to expand and develop
manufacturing capabilities. Although the Company believes that the net proceeds
of the Offering, together with existing cash balances and cash generated from
operations, will be sufficient to fund the operations of the Company for
approximately the next two years, the Company may be required or elect to raise
additional capital before that time. The Company's actual capital requirements
will depend on many factors, including but not limited to, the costs and timing
of the Company's research and development activities, the number and type of
clinical tests the Company is required to conduct in seeking approval of its
products from governmental agencies, the success of the Company's development
efforts, the costs and timing of the expansion of the Company's sales and
marketing activities, the extent to which the Company's existing and new
products gain market acceptance, the Company's ability to maintain existing
collaborative relationships and enter into new collaborative relationships,
competing technological and market developments, the progress of the Company's
commercialization efforts and the commercialization efforts of the Company's
distributors, the costs involved in preparing, filing, prosecuting, maintaining,
enforcing and defending patent claims and other intellectual property rights,
developments related to regulatory and third party reimbursement issues, and
other factors.
 
     To satisfy its capital requirements, the Company may seek to raise funds
through public or private financings, collaborative relationships or other
arrangements. Any additional equity financing may be dilutive to shareholders,
and debt financing, if available, may involve significant restrictive covenants.
Collaborative arrangements, if necessary to raise additional funds, may require
the Company to relinquish its rights to certain of its technologies, products or
marketing territories. Failure to raise capital when needed could have a
material adverse effect on the Company's business, financial condition and
results of operations. There can be no assurance that such financing, if
required, will be available on terms satisfactory to the Company, if at all. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
     UNCERTAINTY OF GOVERNMENT REGULATION. The research, development,
manufacture and marketing of the Company's products are extensively regulated by
the FDA, which requires its approval of drugs and medical devices before they
can be marketed in the United States. Similar approvals are also required from
other regulatory bodies in virtually every developed foreign country before the
Company's products may be marketed in such countries. The regulatory processes
established by these government agencies are lengthy, expensive and uncertain.
In addition, once approval is obtained, that approval may be withdrawn for a
manufacturer's failure to comply with regulatory standards, because of
unforeseen problems related to product safety or as a result of the retroactive
application of changes in the law.
 
     The Company has received approval from the FDA on its New Drug Application
("NDA") for Iontocaine, and the FDA has allowed the Company to market its
electrical dose controllers and electrode products for use with ions of soluble
salts or other drugs under the FDA's 510(k) regulations governing medical
devices. However, the FDA has publicly stated that it intends to require
manufacturers of iontophoretic devices to obtain pre-market approval ("PMA") of
marketed devices currently used with drugs not specifically labeled for
iontophoretic delivery, which would include the Company's dose controller for
use with ions of soluble salts or other drugs, such as Dexamethasone. The FDA's
1994 strategy document states that the enactment of the modified regulatory
procedure was a "high priority" and that the agency intended to publish a
proposed regulation requiring such PMAs in 1996. The agency to date has not
published such a regulation.
 
     If the FDA calls for PMAs, the Company would be required to have a PMA
accepted for filing by the FDA within 90 days after the date of the final
regulation. There can be no assurance that the Company would be able to complete
necessary clinical studies and otherwise prepare and file a PMA within that
period or that any data and information submitted in a PMA would be adequate to
support FDA approval. The Company's failure to submit a PMA and have it accepted
for filing by the FDA within the required timeframe could result in the Company
being required to cease commercial distribution of the Phoresor for use with
ions of soluble salts or other drugs, including Dexamethasone. Upon timely
filing of a PMA, the Company believes (based on
 
                                       14
<PAGE>   16
 
the FDA's announced position as to certain other devices) that the FDA would
permit continued commercial distribution of the Company's dose controller for
use with Dexamethasone during the time necessary to review the PMA. There can be
no assurance, however, that the FDA would do so, nor can any assurance be given
that the FDA would approve a PMA filed by the Company. The FDA also could
condition PMA approval upon approval of an NDA permitting Dexamethasone to be
labeled for use with the Company's dose controller. If the Company were required
to cease commercial distribution of its iontophoretic drug delivery products for
use with Dexamethasone pending approval of a PMA or NDA, the Company's business,
financial conditions and results of operations could be adversely affected. The
Company will be required to obtain further FDA approvals before it may promote
or otherwise market or label any of its present or future drug delivery products
for use with other named drugs. There can be no assurance that such approvals
will be granted, and the process of obtaining them could be extensive,
time-consuming and costly. The time required to obtain FDA approval after filing
an NDA is uncertain and frequently takes several years. Further, the Company has
not yet filed NDAs on any drug other than Iontocaine. In the course of the
practice of medicine, medical practitioners legally can use the Company's
iontophoretic devices for the delivery of Dexamethasone even though the Company
has not filed an NDA for that therapeutic indication and even though the Company
is not permitted to label or promote its device for use with Dexamethasone. The
FDA may require that the Company conduct clinical trials and obtain NDA approval
for the iontophoretic delivery of Dexamethasone using the Company's dose
controllers and electrodes for the treatment of acute local inflammation in
order for the Company to continue to market its products for that therapeutic
indication. There can be no assurance that such clinical trials, if conducted,
would be successful in establishing safety and efficacy or that NDA approval
could be obtained.
 
     There can be no assurance any future products developed by the Company will
prove to be safe and effective or meet all of the applicable regulatory
requirements necessary to be marketed. Data obtained from testing activities can
be susceptible to varying interpretations which could delay, limit or prevent
required regulatory approvals. In addition, the Company may encounter delays or
denials of approval based on a number of factors, including future legislation,
administrative action or changes in FDA policy made during the period of product
development and FDA regulatory review. The Company may encounter similar delays
in foreign countries. Furthermore, approval may entail ongoing requirements for,
among other things, post-marketing studies. Even if a product developer obtains
regulatory approval, a marketed product, its manufacturer and its manufacturing
facilities and pertinent operations are subject to extensive regulation and
periodic inspections. Discovery of previously unknown problems with a product,
manufacturer or facility could result in FDA sanctions, restrictions on a
product or manufacturer, or an order to withdraw and/or recall a specific
product from the market. There can also be no assurance that changes in the
legal or regulatory framework or other subsequent developments will not result
in the limitation, suspension or revocation of regulatory approvals granted to
the Company. Such events, were they to occur, could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     The Company is also required to comply with FDA regulations for
manufacturing practices, which mandate procedures for extensive control and
documentation of product design, control and validation of the manufacturing
process and overall product quality. Foreign regulatory agencies have similar
manufacturing standards. Ongoing compliance with these standards and with
labeling, adverse event reporting and other applicable regulatory requirements
is monitored through periodic inspections and market surveillance by federal,
state and local government agencies and by comparable agencies in other
countries. Any third parties manufacturing the Company's products or supplying
materials or components for such products may also be subject to the foregoing
requirements. If the Company, its management or its third party manufacturers
fail to comply with applicable regulations regarding these manufacturing
practices, the Company could be subject to a number of sanctions, including
fines, injunctions, civil penalties, delays, suspensions or withdrawals of
market approval, seizures or recalls of products, operating restrictions and, in
some cases, criminal prosecutions. See "Business -- Government Regulation."
 
     Under the FDA's regulations, when a manufacturer changes or modifies a
device for which it has received a 510(k) clearance, it is required to obtain an
additional 510(k) clearance for the modified device if the modification
significantly affects the safety or efficacy of the device, or if the
modification results in a
 
                                       15
<PAGE>   17
 
major change in intended use. In such cases, the manufacturer is expected to
make the initial determination as to whether the modification is of a kind that
would require a new 510(k) clearance. The FDA's regulations provide only limited
guidance in making this determination. The FDA has cleared the Company's
electrical dose controller and electrode kits for marketing under a 510(k)
clearance. Since obtaining its 510(k) clearances, the Company has made
modifications to its products. Based on the checklist developed by the FDA to
assist manufacturers in determining whether they are required to obtain a 510(k)
clearance for a modified device, the Company has determined that a new 510(k)
submission was not required in connection with the commercial introduction of
such products. However, there can be no assurance that the FDA will not require
the Company to obtain additional 510(k) clearances with respect to those
products. If the FDA requires the Company to submit a new 510(k) notice for any
device modification, the Company may be prohibited from marketing the modified
device until the 510(k) notice is cleared by the FDA.
 
   
     The Company may be subject to certain user fees that the FDA is authorized
to collect under the Food and Drug Modernization Act of 1997, which reauthorized
the user fees established in the Prescription Drug User Fees Act of 1992 for
certain drugs.
    
 
     Because of the known safety and efficacy profile of Dexamethasone and other
approved drugs for which the Company may seek NDA approval for iontophoretic
delivery, the clinical trials and other studies may not be as lengthy or
extensive as would be required for unapproved new drugs that are subject to full
NDA requirements. This strategy, however, depends upon the Company's ability to
obtain a contractual right to reference the safety and efficacy data for such
drugs contained in approved NDAs held by other entities. The Company has
obtained a right to reference safety and efficacy data for Dexamethasone. There
can be no assurance that the Company will be able to obtain a right of reference
for all unapproved drugs that may be used for iontophoretic delivery. The
Company's failure to obtain a right of reference to safety and efficacy data for
any drug for which the Company would like to obtain approval for iontophoretic
delivery could result in the Company being required to independently satisfy any
requirements regulatory agencies may impose with respect to such references,
which could delay the Company's use of such drug or increase the Company's
costs. See "Business -- Government Regulation."
 
   
     DEPENDENCE ON SINGLE SOURCES OF SUPPLY. A key material used in many of the
Company's current electrode products is available only from a single supplier.
In addition, the Company obtains Iontocaine from Abbott Laboratories under a
contract expiring in December 1998. The Company also has the right to obtain
Dexamethasone from Luitpold Pharmaceuticals, Inc./American Regent Laboratories,
Inc. under a contract expiring in January 2005. The Company believes that, if
necessary, alternative sources can be developed or alternate materials can be
substituted for each of these single-sourced materials. Although the Company has
not experienced difficulty acquiring these materials on commercially reasonable
terms and in sufficient quantities to maintain required production levels, no
assurance can be given that price increases or interruptions in the supply of
these materials will not occur in the future or that the Company will not have
to seek alternate suppliers or obtain substitute materials, which may require
additional product validations and regulatory submissions. Any significant price
increase, interruption of supply, inability to secure an alternate source or
qualify a substitute material could have a material adverse effect on the
Company's ability to manufacture its products or to obtain or maintain
regulatory approval of its products, any of which could have a material adverse
effect on the Company's business, financial condition and results of operations.
    
 
     The Company's current dose controllers are manufactured under contract with
a third party electronics manufacturer. The Company has not experienced any
difficulty in obtaining adequate supplies of this product from the manufacturer,
but there can be no assurance that an interruption in supply will not occur in
the future or, if there is an interruption in supply, that the Company would be
able to identify, qualify and validate an alternate source of supply within a
reasonable period of time or that such an interruption would not have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business -- Manufacturing."
 
     LIMITED MANUFACTURING EXPERIENCE. The Company manufactures its
iontophoretic drug delivery electrodes in quantities sufficient to satisfy its
current level of product sales. To meet anticipated increases in sales, the
Company may need to increase its production significantly beyond its present
manufacturing capacity.
 
                                       16
<PAGE>   18
 
Accordingly, the Company may be required to increase its manufacturing
capacities or to contract with another party to manufacture its products. There
can be no assurance the Company can successfully increase its capacity on a
profitable basis, or contract with another party on terms acceptable to the
Company, if at all.
 
     The Company's manufacturing process is labor intensive and, therefore,
significant increases in production volume will likely require changes in both
product and process design in order to facilitate increased automation in the
Company's production processes. There can be no assurance such changes in
products or processes or efforts to automate all or portions of the Company's
manufacturing process will be successful or that manufacturing or quality
control problems will not arise as the Company increases production volumes of
its existing products or begins production of new products, any of which events
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
     The Company believes its facilities operate in accordance with the Quality
System Regulations currently prescribed by the FDA and in substantial compliance
with ISO 9001 and CE Mark standards. The Company has Good Manufacturing
Practices ("GMP") audits conducted by a qualified, independent organization on a
regular basis and recently obtained its official ISO 9001, and CE Mark
certification. There can be no assurance the Company will be able to maintain
such compliance, particularly if the scale of the Company's manufacturing
operations increases. See "Use of Proceeds," "Business -- Manufacturing" and
"Business -- Government Regulation."
 
     POTENTIAL HEALTH CARE REFORM. Political, economic and regulatory influences
are subjecting the health care industry in the United States to fundamental
changes. The Company anticipates the United States Congress, state legislatures
and the private sector will continue to review and assess alternative health
care delivery and payment systems. Potential approaches that have been
considered include mandated basic health care benefits, controls on health care
spending through limitations on the growth of private health insurance premiums
and Medicare and Medicaid spending, the creation of large insurance purchasing
groups, price controls and other fundamental changes to the health care delivery
system. The Company believes the legislative debate will continue in the future,
and that market forces will demand reduced costs. The Company cannot predict
what impact the adoption of any future federal or state health care reform
measures, private sector reform or other market forces may have on its business,
either currently or in the future. Even the existence of pending health care
reform could have a material adverse impact on the Company by making it
difficult to raise capital or establish collaborative relationships. See
"Business -- Government Regulation."
 
     UNCERTAINTY OF HEALTH CARE REIMBURSEMENT. The Company's ability to
commercialize its products successfully will depend in part on the extent to
which reimbursement for the costs of those products and related treatments will
be available from government health administration authorities, private health
insurers and other organizations in the United States and in foreign markets
where the Company's products will be sold and used. Third party payors can
affect the pricing or relative attractiveness of the Company's products by
regulating the reimbursement they provide on the Company's or competing products
or therapies. There can be no assurance such reimbursement will continue at
present levels, if at all. Furthermore, significant uncertainty exists as to the
reimbursement status of new health care products. There can be no assurance
third party coverage will be available for the Company's future products at
levels necessary for commercial success. Domestic and foreign government and
third party payors are increasingly attempting to contain health care costs by
limiting both coverage and the level of reimbursement for new therapeutic
products. If adequate coverage and reimbursement levels are not provided by such
government and third party payors for uses of the Company's products, the market
acceptance of those products could be adversely affected. Given the recent
efforts to control and reduce health care costs in the United States and in
foreign markets, there can be no assurance the currently available levels of
reimbursement will continue to be available in the future for the Company's
existing products or products under development.
 
     Effective October 1, 1991, the Health Care Financing Administration adopted
new regulations providing for the treatment of capital related costs for medical
products. Under the regulations, providers are reimbursed for those capital
costs on a per diagnosis basis at fixed rates unrelated to actual costs.
Equipment costs generally are not reimbursed separately, but are included in a
single, fixed rate, per patient reimbursement. These regulations are being
phased in over a 10 year period and, although the full implications of the
 
                                       17
<PAGE>   19
 
regulations cannot yet be known, the Company believes the new regulations may
place more pressure on hospital operating margins, causing them to limit capital
expenditures. The Company is unable to predict what adverse impact on the
Company, if any, additional government regulations, legislation or initiatives
or changes by other payors affecting reimbursement or other matters that may
influence decisions to obtain medical devices may have.
 
     RETENTION AND ATTRACTION OF KEY EMPLOYEES. The Company is highly dependent
on its ability to continue to attract and retain qualified scientific,
managerial and manufacturing personnel. There is intense competition for
qualified personnel in the Company's area of activity, and there can be no
assurance the Company will be able to continue to attract and retain the
qualified personnel necessary for the development of its business. Loss of the
services of or the failure to recruit qualified scientific, managerial or
manufacturing personnel could have a material adverse effect on the Company's
business, financial condition and results of operations. The Company does not
carry key-man insurance with respect to any of its executives or employees. See
"Business -- Employees" and "Management."
 
     RISK OF PRODUCT LIABILITY AND AVAILABILITY OF INSURANCE. The testing,
marketing and sale of drug delivery and related pharmaceutical products for use
in humans involves unavoidable risks. The use of the Company's products in
clinical trials and the sale of its products upon approval may expose the
Company to potential product liability resulting from the use of such products.
In addition, the existence of a product liability claim could have an adverse
effect on the Company's sales of that product, could result in a recall of that
product or require a change in the indications for which it may be used. Product
liability insurance in the Company's industry is expensive and difficult to
obtain.
 
     Although the Company currently has product liability insurance with an
annual limit of $1,000,000 per occurrence and $1,000,000 in the aggregate, there
can be no assurance the existing coverage is adequate. The Company will seek to
maintain and appropriately increase its insurance coverage as its product sales
increase and the clinical development of its new product applications progress.
There can be no assurance, however, that the Company will be able to maintain
its current levels of insurance on acceptable terms, will be able to secure
increased coverage as the commercialization of its products proceeds or that any
particular level of insurance will provide adequate protection against potential
liabilities. The obligation to pay any product liability claim brought against
the Company which is in excess of the Company's insurance coverage could have a
material adverse effect upon the Company's business, financial condition and
results of operations.
 
     ABSENCE OF PRIOR TRADING MARKET; POTENTIAL VOLATILITY OF SHARE PRICE. Prior
to the Offering, there has been no market for the Common Shares, and there can
be no assurance an active trading market will develop or, if one does develop,
that it will be maintained. The public offering price of the Common Shares
offered hereby will be determined by negotiations between the Company and the
representatives of the Underwriters. For a description of the factors to be
considered in determining the public offering price, see "Underwriting." The
market price of the Common Shares, like that of the common shares of many other
drug delivery, pharmaceutical, biotechnology, medical device and other high
technology companies, is likely to be highly volatile. Factors such as
fluctuations or volatility in the Company's operating results, announcements of
technological innovations, results of clinical trials or new commercial products
by the Company or competitors, regulatory developments in the United States or
foreign countries, changes in the current structure of health care financing and
payment systems, developments in or disputes regarding patent or other
proprietary rights, general market conditions, economic and other external
factors may have a significant effect on the market price of the Common Shares.
 
     SHARES ELIGIBLE FOR FUTURE SALE; POSSIBLE ADVERSE EFFECT ON FUTURE MARKET
PRICE. Sales of substantial amounts of Common Shares (including shares issuable
upon exercise of outstanding options and warrants) in the public market after
the Offering could adversely affect the market price of the Common Shares. Such
sales could also make it more difficult for the Company to sell equity
securities or equity-related securities in the future at a time and price that
the Company deems appropriate. Upon completion of the Offering, the Company will
have outstanding an aggregate of 6,360,204 Common Shares. In addition, the
Company has reserved for issuance 679,303 shares issuable upon exercise of
outstanding options and warrants. The 1,700,000 Common Shares offered hereby
will be freely transferable without restriction or further registration
 
                                       18

under the Securities Act of 1933, as amended (the "Securities Act"), except for
shares which may be acquired by "affiliates" of the Company as that term is
defined in Rule 144 under the Securities Act. The remaining Common Shares held
by existing shareholders are "restricted securities" as that term is defined in
Rule 144. Restricted securities may be sold in the public market only if they
are registered or if they qualify for exemption from registration under Rules
144 or 701 or other provisions of the Securities Act. Pursuant to certain
"lock-up" agreements, the Company's directors, officers and certain of its
shareholders who collectively hold an aggregate of 4,560,934 Common Shares,
together with the Company, have agreed, for a period of 180 days following the
date of this Prospectus, not to offer, pledge, sell, contract to sell, grant any
option for the sale of, or otherwise dispose of, directly or indirectly, any
Common Shares without the prior written consent of EVEREN Securities, Inc.
Following the lock-up periods, approximately 1,903,533 Common Shares will be
eligible for sale in the public market without restriction under Rule 144(k) and
an additional 79,808 Common Shares will be eligible for sale subject to certain
volume, manner of sale and other restrictions of Rule 144. All restricted shares
held by existing shareholders of the Company not subject to lock-up agreements
will be eligible for immediate sale in the public market without restriction
under Rule 144(k). In addition, holders of stock options or warrants exercisable
for an aggregate of approximately 220,227 Common Shares have entered into
agreements prohibiting the sales of the underlying Common Shares for 180 days
following the date of this Prospectus. See "Principal Shareholders," "Shares
Eligible for Future Sale" and "Underwriting."
 
     POTENTIAL DILUTION; ABSENCE OF DIVIDENDS. The initial public offering price
will be substantially higher than the tangible book value per Common Share.
Investors purchasing Common Shares in the Offering will therefore incur an
immediate and substantial dilution in tangible book value. In addition,
investors purchasing Common Shares in the Offering will incur additional
dilution to the extent outstanding stock options and warrants are exercised. The
Company has not paid any cash dividends since inception and does not anticipate
paying cash dividends in the foreseeable future. See "Dividend Policy" and
"Dilution." If the initial public offering price is less than $12.00 per share,
the number of Common Shares that Elan will have the right to purchase for the
$10.2 million will be equal to $10.2 million divided by the initial public
offering price. As a result of any issuance to Elan of shares in excess of
833,333, investors in the Offering will own a lower percentage of the total
Common Shares outstanding after the closing of the Offering. See "Transactions
Related to the Offering" and "Certain Transactions."
 
     MANAGEMENT DISCRETION OVER PROCEEDS OF THE OFFERING. The Company's
management will retain broad discretion as to the allocation of a significant
portion of the net proceeds of the Offering. As a result of that discretion, the
Company's management could allocate the proceeds of the Offering to uses which
the shareholders may not deem desirable. In addition, there can be no assurance
the proceeds can or will be invested to yield an appropriate return. See "Use of
Proceeds" and "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
     CONTROL BY EXISTING SHAREHOLDERS. Following the Offering, the Company's
directors, executives and principal shareholders will beneficially own
approximately 66.7% of the outstanding Common Shares. Accordingly, if such
persons act in concert, they will have the power to elect the Company's
directors and, subject to certain limitations, effect or preclude fundamental
corporate transactions involving the Company. This concentration of ownership
may have the effect of delaying or preventing a change of control of the
Company. See "Principal Shareholders" and "Description of Capital Shares."
 
     ANTI-TAKEOVER PROVISIONS OF THE COMPANY'S ARTICLES OF INCORPORATION; UTAH
LAW AND CERTAIN OF THE COMPANY'S AGREEMENTS. Certain provisions of the Company's
Articles of Incorporation, as amended, and the provisions of the Utah Revised
Business Corporation Act may have the effect of deterring hostile takeovers or
delaying or preventing changes in control or management of the Company,
including transactions in which shareholders might otherwise receive a premium
for their shares over then-current market prices. The Company's Articles of
Incorporation provide, among other things, for a classified Board of Directors,
and provide that members of the Board of Directors may be removed only for cause
upon the affirmative vote of the holders of at least two-thirds of the Common
Shares. The Company's Board of Directors is also authorized to issue Preferred
Shares and, in connection with any such issuance, determine the price, rights,
preferences and privileges of those shares without further vote or action by the
Company's shareholders. Any such
 
                                       19
<PAGE>   21
 
Preferred Shares may have other rights, including economic rights, which are
senior to the Common Shares and, as a result, the issuance of such Preferred
Shares could have a material adverse effect on the market value of the Common
Shares. See "Description of Capital Shares."
 
     Certain of the provisions of a cross-license agreement between the Company
and Alza may have the effect of deferring, delaying or preventing a change in
control of the Company, a merger involving the Company or the assignment or
transfer of certain technologies of the Company. Under the agreement, the
Company and Alza, among other things, exchanged non-exclusive, royalty free
rights to certain patented technologies which each party believed to be of
significant strategic importance to the potential technological success of many
iontophoretic drug delivery applications. Both parties are prohibited from
assigning their rights under the agreement to certain named companies or any
other entity that derives more than 50 percent of its income from the
development, licensing and/or sale of drug delivery systems to other
pharmaceutical companies without first receiving the consent of the other party.
Restrictions imposed on the Company's ability to assign its rights under this
agreement may limit the Company's ability to capitalize on the commercial and
other economic potential of these technologies through a technology license,
asset sale, merger, combination or similar transaction, and could have an
adverse effect on the market value of the Common Shares. See
"Business -- Collaborative Relationships and Licenses."
 
     ENVIRONMENTAL MATTERS. The Company's research and development activities
involve the controlled use of hazardous materials, chemicals and various
radioactive compounds. These materials, and their use, disposal and handling,
are extensively regulated by federal, state and local government authorities.
Although the Company believes its safety procedures for handling and disposing
of such materials comply in all material respects with the standards prescribed
by state and federal regulations, the risk of accidental environmental
contamination or personal injury from these materials cannot be completely
eliminated. In the event of such an accident, the Company could be held liable
for any damages and any such liability could exceed the resources of the
Company. There can be no assurance the Company will not be required to incur
significant costs to comply with such environmental and health and safety laws
and regulations in the future, particularly if the Company develops additional
manufacturing or research facilities and capacity. See "Business -- Government
Regulation."
 
     FORWARD-LOOKING STATEMENTS. Certain statements under the headings
"Prospectus Summary," "Risk Factors," "Use of Proceeds," "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business," and elsewhere in this Prospectus constitute "forward-looking
statements" within the meaning of the rules and regulations promulgated by the
Securities and Exchange Commission. Such forward-looking statements may be
identified by the use of terminology such as "may," "will," "expect,"
"anticipate," "intend," "designed," "estimate," "should," or "continue" or the
negatives thereof or other variations thereon or comparable terminology. Such
forward-looking statements involve known and unknown risks, uncertainties and
other factors which may cause the actual results, performance or achievements of
the Company, or industry results, to be materially different from any future
results, performance or achievements expressed or implied by such
forward-looking statements. These risks, uncertainties and other factors
include, among other things, the following: the Company's sporadic history of
profitability and the continuing uncertainty of its profitability; the Company's
ability to develop and introduce new products; the uncertainty of market
acceptance of the Company's new and existing products and their market
penetration to date; the uncertainties related to the Company's product
development programs; the Company's reliance on collaborative partners and
licenses; the Company's limited sales, marketing and distribution experience and
current dependence on distributors; the risks associated with obtaining
governmental approval of the Company's products; the highly competitive industry
in which the Company operates and the rapid pace of technological change within
that industry; the uncertainty of patented and proprietary technology protection
and the Company's reliance on such patented and proprietary technology
(including reliance on technology licensed from third parties); changes in or
failure to comply with governmental regulation, the uncertainty of third party
reimbursement for the Company's products; the Company's dependence on key
employees; general economic and business conditions and other factors referenced
in this Prospectus.

                      TRANSACTIONS RELATED TO THE OFFERING
 
     In March 1997, the Company entered into a series of agreements with Elan
pursuant to which the Company acquired certain in-process research and
development programs, including exclusive world-wide rights to certain
iontophoretic patents, know-how and clinical data (the "Elan Agreements"). The
Company acquired the Elan technology by issuing Elan two promissory notes, a
$10.0 million note and a $5.0 million note (collectively, the "Elan Notes"),
together with a warrant to purchase 104,166 Common Shares at an exercise price
of $21.60 per share and agreed to pay Elan royalties on any net revenues derived
by the Company from its products.
 
     Concurrently with the closing of the Offering, Elan will purchase directly
from the Company, in private placement transactions (i) 833,333 Common Shares
(subject to adjustment under certain circumstances) for approximately $10.2
million (the amount outstanding under the $10.0 million note) and (ii)
approximately $5.1 million of Common Shares at a price per share equal to the
initial public offering price hereunder (425,000 shares assuming an initial
public offering price of $12.00 per share) (collectively, the "Elan Shares").
Simultaneously with such purchases, the Company will repay the Elan Notes,
including interest thereon. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations," "Business -- Collaborative
Relationships and Licenses," "Certain Transactions," "Description of Capital
Shares -- Warrants" and "Underwriting."
 
     If the initial public offering price of the Common Shares is less than
$12.00 per share, the number of Common Shares that Elan will have the right to
purchase for the approximately $10.2 million (the amount outstanding under the
$10.0 million note) will be equal to that amount divided by the initial offering
price. If, as a result of Elan's purchase of the Elan Shares, Elan's aggregate
interest in the Common Shares exceeds 19.9% of the outstanding Common Shares,
Elan may elect to receive non-voting preferred shares to the extent of such
excess. Any such preferred shares would rank pari passu with the Common Shares,
and would be non-voting and convertible into Common Shares on a one-for-one
basis initially. See "Certain Transactions."
 
     Effective November 1, 1997, the Company, Novartis and Dermion amended the
terms of their contractual relationships. Among other things, Novartis exchanged
its 20% interest in Dermion for 238,541 Common Shares and warrants to acquire an
additional 18,750 Common Shares at an exercise price of $21.60 per share. See
"Business -- Collaborative Relationships and Licenses" and "Description of
Capital Shares -- Warrants."

<PAGE>   23
 
                                USE OF PROCEEDS
 
     The net proceeds of the Offering are estimated to be approximately $18.1
million ($20.9 million if the Underwriters' exercise the over-allotment option
in full) at an assumed initial public offering price of $12.00 per Common Share.
The Company intends to use approximately $11.8 million of the net proceeds from
the Offering to conduct research and development activities. The balance of the
net proceeds (approximately $6.3 million) will be used to expand the Company's
sales and marketing capabilities and to consolidate and equip its facilities, as
well as for working capital or other general corporate purposes. The Company may
also use a portion of the net proceeds from the Offering for the in-licensing or
acquisition of technologies, businesses or products that are complementary to
those of the Company, although no specific acquisitions are being negotiated as
of the date hereof, and no portion of the net proceeds has been allocated for
any such acquisition. Pending such uses, the Company intends to invest the
proceeds of the Offering in short term, investment grade, interest-bearing
securities. See "Transactions Related to the Offering" and "Certain
Transactions."
 
     Elan has agreed to purchase in private placement transactions concurrently
with the closing of the Offering the Elan Shares for approximately $15.3
million. Simultaneously with such purchases, the Company will repay the Elan
Notes, including interest thereon. See "Transactions Related to the Offering"
and "Certain Transactions."
 
     The actual amount expended and the timing of the use of the net proceeds of
the Offering for each purpose set forth in the preceding paragraph may vary
significantly depending upon a number of factors, including the costs and timing
of the Company's research and development activities, the number and type of
clinical tests the Company is required to conduct in seeking approval of its
products from governmental agencies, the success of the Company's developmental
efforts, the costs and timing of the expansion of the Company's sales and
marketing activities, the extent to which the Company's existing and new
products gain market acceptance, the Company's ability to maintain existing
collaborative relationships and enter into new collaborative relationships,
competing technological, market and patent developments, the progress of the
Company's commercialization efforts and the commercialization efforts of the
Company's distributors and co-marketers, the costs involved in preparing,
filing, prosecuting, maintaining and enforcing patent claims and other
intellectual property rights, developments related to regulatory and third party
reimbursement issues, and other factors. The Company's management will retain
broad discretion as to the allocation of a significant portion of the net
proceeds of the Offering. See "Risk Factors -- Management Discretion Over
Proceeds of the Offering."

     The following table sets forth (a) the actual capitalization of the Company
as of September 30, 1997 (giving effect to the 1-for-4.8 reverse split) and (b)
the pro forma capitalization of the Company as adjusted to reflect (i) the
issuance and sale of 1,700,000 Common Shares offered hereby, at an assumed

proceeds therefrom; (ii) the sale of the Elan Shares to Elan and the
simultaneous repayment of the Elan Notes, including interest thereon,
concurrently with the closing of the Offering; (iii) the mandatory conversion of
the outstanding Series C Preferred Shares into 28,800 Common Shares concurrently
with the closing of the Offering; and (iv) the exchange of Novartis' 20% equity
interest in Dermion for 238,541 Common Shares, which was effected November 1,
1997. The number of the Elan Shares is dependent upon the initial public
offering price. See "Transactions Related to the Offering" and "Certain
Transactions."

                                    DILUTION
 
     The pro forma net tangible book value of the Company as of September 30,
1997 (giving effect to the 1-for-4.8 reverse split), was $7,483,000, or $1.61
per share. Pro forma net tangible book value per share is equal to total
tangible assets of the Company, less total pro forma liabilities, divided by the
pro forma number of Common Shares outstanding, giving effect to (i) the sale of
the Elan Shares to Elan and the simultaneous repayment of the Elan Notes,
including interest thereon, concurrently with the closing of the Offering; (ii)
the mandatory conversion of the outstanding Series C Preferred Shares into
28,800 Common Shares concurrently with the closing of the Offering; and (iii)
the exchange of Novartis' 20% equity interest in Dermion for 238,541 Common
Shares, which was effected November 1, 1997. Without taking into account any
other changes in pro forma net tangible book value after September 30, 1997
other than to give effect to the issuance and sale of the 1,700,000 Common
Shares offered hereby at an assumed initial public offering price of $12.00 per
share and the receipt of the net proceeds therefrom, the pro forma net tangible
book value of the Company as of September 30, 1997 would have been approximately
$25,684,000, or $4.04 per share. This represents an immediate increase in pro
forma net tangible book value of $2.43 per share to existing shareholders and an
immediate dilution in pro forma net tangible book value of $7.96 per share to
investors in the Common Shares offered hereby. The number of the Elan Shares is
dependent upon the initial public offering price, See "Transactions Related to
the Offering" and "Certain Transactions." The following table illustrates the

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following should be read in conjunction with "Selected Consolidated
Financial Data" and the Company's Consolidated Financial Statements and Notes
thereto appearing elsewhere in this Prospectus. This Management's Discussion and
Analysis of Financial Condition and Results of Operations and other parts of
this Prospectus contain 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 a difference include, but are not limited to, those discussed in "Risk
Factors."
 
OVERVIEW
 
     The Company develops, manufactures and commercializes controllable drug
delivery systems using iontophoretic technology. The majority of the Company's
revenues has been generated through the sale of its iontophoretic drug delivery
products in the physical therapy market for use in the delivery of Dexamethasone
and contract research revenues from the Company's collaboration with Novartis.
The Company recently introduced its local dermal anesthesia products into the
market place and, to date, has not realized significant revenue from the sales
of such products. Since its inception, the Company has generally incurred
operating losses and it expects to incur additional operating losses over the
next several years as a result of anticipated costs associated with a
significant increase in internally funded research, development and clinical
trial activities relating to new applications for its iontophoretic drug
delivery technologies, development of a dedicated sales force and the
consolidation and equipping of its facilities. As of September 30, 1997, the
Company's accumulated deficit was approximately $21.6 million. The Company's
ability to achieve and sustain profitability will depend on its ability to
achieve market acceptance and successfully expand sales of its existing
products, as well as successfully complete the development of, receive
regulatory approvals for, and successfully manufacture and market, its products
under development, as to which there can be no assurance.
 
RESULTS OF OPERATIONS
 
  THREE MONTHS ENDED SEPTEMBER 30, 1996 AND 1997
 
     Revenues. Product sales increased 10% from $1.8 million in the three months
ended September 30, 1996 to $2.0 million in the three months ended September 30,
1997. The increase can be attributed to higher sales of the Company's
iontophoretic drug delivery products for the treatment of local inflammatory
conditions resulting from overall market growth in this segment.
 
     Contract research revenues, royalties and license fees decreased 23% from
$649,000 in the three months ended September 30, 1996 to $503,000 in the three
months ended September 30, 1997. This decrease can be attributed to the
Company's receipt of a milestone payment pursuant to its research and
development agreement with Novartis during the three months ended September 30,
1996.
 
     Costs of Products Sold. Costs of products sold increased 9% from $821,000
in the three months ended September 30, 1996 to $893,000 in the three months
ended September 30, 1997, reflecting increased material and labor costs
associated with higher unit sales volume.
 
     Research and Development Expense. Research and development expenditures
decreased 4% from $391,000 in the three months ended September 30, 1996 to
$375,000 in the three months ended September 30, 1997. This decrease reflects
differences in the timing of certain expenditures on the Company's internally
financed product development projects.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 38%, from $769,000 in the three months ended
September 30, 1996 to $1.1 million in the three months ended September 30, 1997.
The increase to the current period can be attributed primarily to the
recruiting, personnel and other sales and marketing costs associated with the
Company's continued investment in the market introduction of Numby Stuff. In
addition, the Company realized increased costs associated with routine
maintenance and prosecution of the patent portfolio acquired from Elan.
 
                                       26
<PAGE>   28
 
     Other Costs and Expenses. Interest expense increased from $1,000 in the
three months ended September 30, 1996 to $287,000 in the three months ended
September 30, 1997. This increase can be attributed to the recognition of
non-cash interest expense on $15.0 million in notes issued to Elan in connection
with the Elan Agreements. Interest income and other miscellaneous income was
$58,000 in the three months ended September 30, 1996, compared to $91,000 in the
three months ended September 30, 1997, reflecting interest earnings on higher
average invested cash balances during the current period.
 
     The Company has substantial net operating loss carryforwards which, under
the current "change of ownership" rules of the Internal Revenue Code, may be
subject to substantial annual limitation. Income taxes for the three months
ended September 30, 1996 reflect the Company's effective income tax rate for
fiscal 1997. No income tax expense was recognized for the three months ended
September 30, 1997, which reflects management's estimate of its fiscal 1998 tax
position.
 
     Income (loss) from Continuing Operations. Income from continuing operations
of $474,000 in the three months ended September 30, 1996 compares to a loss from
continuing operations of $36,000 in the three months ended September 30, 1997.
The decrease in fiscal 1997 can be attributed to the receipt of the milestone
payment from Novartis in the prior year, non-cash interest charges on the Elan
indebtedness and the Company's investment in the sales and marketing of Numby
Stuff.
 
  FISCAL YEARS ENDED JUNE 30, 1996 AND 1997
 
     Revenues. Product sales increased 10% from $6.8 million in fiscal 1996 to
$7.5 million in fiscal 1997. This increase can be attributed to increased sales
of the Company's iontophoretic drug delivery products for the treatment of local
inflammatory conditions resulting from the first full year of sales of the
Company's newly introduced electrode kits for this market segment.
 
     Contract research revenues, royalties and license fees decreased 25% from
$2.4 million in fiscal 1996 to $1.8 million in fiscal 1997. During fiscal 1996,
the Company entered into a research and development agreement with Novartis to
develop proprietary iontophoretic drug delivery systems for Novartis drugs.
Pursuant to the agreement, the Company received contract research revenues and
other payments of $1.4 million and $1.8 million, respectively, in fiscal 1996
and 1997. In addition, in fiscal 1996, the Company received a one-time license
fee of $1.0 million. Contract research revenues received during fiscal 1997 and
1996 pursuant to the Novartis agreement covered a substantial portion of the
Company's research and development expenses.
 
     Costs of Products Sold. Costs of products sold increased 6% from $3.1
million in fiscal 1996 to $3.3 million in fiscal 1997, reflecting increased
costs attributable to higher material and labor costs resulting from higher unit
sales volume. Costs of products sold decreased slightly as a percent of product
sales due to productivity gains which were offset, in part, by increased costs
associated with new product introductions.
 
     Research and Development Expense. Research and development expenditures
increased 36%, from $1.1 million in fiscal 1996 to $1.5 million in fiscal 1997.
The increase reflects increased costs of personnel and other expenditures
associated with the development programs conducted under the Novartis agreement,
as well as research and development expenditures on the Company's internally
financed product development projects.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 6%, from $3.3 million in fiscal 1996 to $3.5
million in fiscal 1997. The increase in fiscal 1997 can be attributed to the
recruiting, personnel and other sales and marketing costs associated with the
Company's market introduction of Numby Stuff. The increase was offset, in part,
by decreases in general and administrative expenses.
 
     Non-Recurring Charges. In March 1997, the Company entered into the Elan
Agreements, pursuant to which the Company acquired certain rights to Elan's
in-process research and development relating to iontophoretic drug delivery,
including issued and pending United States and foreign patents, know-how and
clinical data. As a result of this transaction, the Company recorded a
non-recurring charge of approximately $15.1 million.
 
                                       27
<PAGE>   29
 
     During fiscal 1996, the Company recorded a non-recurring charge of $430,000
for costs incurred in connection with the settlement of a trade-dress
infringement suit brought by a competitor of the Company relating to a newly
developed series of the Company's electrode kits for the treatment of acute
local inflammation (the "Litigation").
 
     Other Costs and Expenses. Interest expense increased from $9,000 in fiscal
1996 to $242,000 in fiscal 1997. This increase can be attributed to the
recognition of non-cash interest expense on $15.0 million in notes issued to
Elan in connection with the Elan Agreements. Interest income and other
miscellaneous income was $167,000 in fiscal 1996, compared to $291,000 in fiscal
1997, reflecting interest earnings on higher average cash balances during fiscal
1997.
 
     The Company has substantial net operating loss carryforwards. Income taxes
in both periods reflect estimated alternative minimum tax liabilities, offset by
the recognition of future tax benefits resulting from the allocation of income
tax expense, at statutory rates, to the pre-tax income of the Company's
discontinued operations.
 
     Income (loss) from Continuing Operations. Income from continuing operations
of $1.5 million in fiscal 1996 compares to a loss from continuing operations of
$14.1 million in fiscal 1997. Excluding the non-recurring charges in both fiscal
years, income from continuing operations decreased from $2.0 million in fiscal
1996 to $1.0 million in fiscal 1997. The decrease in fiscal 1997 can be
attributed primarily to the one time $1.0 million license fee the Company
received from Novartis in fiscal 1996.
 
  FISCAL YEARS ENDED JUNE 30, 1995 AND 1996
 
     Revenues. Product sales decreased 3% from $7.0 million in fiscal 1995 to
$6.8 million in fiscal 1996. Sales increases during fiscal 1996 were offset by
the full year effect of the loss of sales resulting from the acquisition, during
fiscal 1995, of several of the Company's key product distributors by a major
competitor in the physical therapy market. Sales in fiscal 1996 were also
negatively impacted by the Litigation, which delayed the launch of the newly
developed series of electrode kits for the treatment of acute local
inflammation. During fiscal 1996, the Company realized $1.4 million in revenues
from contract research and development services and a one-time $1.0 million
license fee in connection with its research and development agreement with
Novartis, offsetting the decrease in product sales in fiscal 1996.
 
     Cost of Products Sold. Costs of products sold decreased 9% from $3.4
million in fiscal 1995 to $3.1 million in fiscal 1996. This improvement was
attributed to increased manufacturing efficiencies and lower materials costs
resulting from the use of new materials and sources of supply and reductions in
manufacturing overhead.
 
     Research and Development Expense. Research and development expense
decreased 27% from $1.5 million in fiscal 1995 to $1.1 million in fiscal 1996.
Research and development expense during fiscal 1996 consisted primarily of
expenditures relating to the Company's research programs with Novartis, which,
in the aggregate, were lower than the research and development expenditures in
fiscal 1995. The Company's research and development expenditures in fiscal 1995
included costs relating to the Company's NDA filing for the approval of
Iontocaine, as well as expenditures relating to the Company's collaborative
development projects with Laboratoires Fournier.
 
     Non-Recurring Charges. The Company recorded a non-recurring charge of
$430,000 during fiscal 1996 for costs incurred in connection with the
Litigation.
 
     Other Costs and Expenses. Interest expense decreased from $32,000 in fiscal
1995 to $9,000 in fiscal 1996 due to the lower average principal balance due
under the Company's term loan. Interest income and other miscellaneous income
was $120,000 in fiscal 1995, compared to $167,000 in fiscal 1996, primarily due
to interest earnings on higher average cash balances from operating cash flows,
and the Company's sale to Novartis of a 20% interest in Dermion in fiscal 1996.
 
     The Company has substantial net operating loss carryforwards. The credit
provision for income taxes in fiscal 1996 reflects the recognition of future tax
benefits resulting from the allocation of income tax expense, at
 
                                       28
<PAGE>   30
 
statutory rates, to the pre-tax income of the Company's discontinued operations,
offset, in part, by estimated alternative minimum tax liabilities. The credit
provision for income taxes in fiscal 1995 reflects the recognition of future tax
benefits resulting from the allocation of income tax expense, at statutory
rates, to the pre-tax income of the Company's discontinued operations.
 
     Income (loss) from Continuing Operations. The loss from continuing
operations of $949,000 in fiscal 1995 compares to income from continuing
operations of $1.5 million in fiscal 1996. Excluding the non-recurring charge in
fiscal 1996, the difference is attributable primarily to the Company's receipt,
in fiscal 1996, of contract research and development revenues and a $1.0 million
one-time license fee in connection with the Company's research and development
agreement with Novartis.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Prior to fiscal 1996, the Company funded its operating losses primarily
through private equity financing, convertible debt arrangements, capital lease
financing, and collateralized bank loans. Beginning in fiscal 1996, the
Company's operating and research activities have been internally funded,
primarily as a result of the research and development revenues and license fees
the Company has received from Novartis.
 
     As of September 30, 1997, the Company had cash and cash equivalents
totaling approximately $5.9 million. Cash in excess of immediate requirements is
invested in a manner which is intended to maximize liquidity and return while
minimizing investment risk, and, whenever possible, the Company seeks to
minimize the potential effects of concentration of credit risk.
 
     In the three month period ended September 30, 1996, the Company generated
$829,000 of cash from operating activities compared to a use of cash of
approximately $194,000 in the three month period ended September 30, 1997. This
decrease in cash flow is due to the Company's net loss for the current period,
as discussed above, and to changes in working capital during the three month
period ended September 30, 1997. The Company generated approximately $1.0
million of cash from operating activities during fiscal 1997, compared to $2.2
million in fiscal 1996. The decrease can be attributed primarily to the one-time
license fee received from Novartis in fiscal 1996 and an increased net
investment in working capital in fiscal 1997. In fiscal 1996, the Company
generated cash of $2.2 million from operating activities, compared to a use of
cash of $298,000 in fiscal 1995. The transition to generating cash in fiscal
1996 can be attributed to the research and development funding and the one-time
license fee the Company received from Novartis in fiscal 1996. During fiscal
1995, the Company's investment in finished goods inventory increased in
preparation for the launch of a new electrode kit for local inflammation and
accrued liabilities increased due to the reserve established for the estimated
costs of the Company's planned facilities consolidation.
 
     Historically, the Company's operations have not been capital intensive and,
therefore, its investment in property, plant and equipment during the periods
presented has not been significant. The Company anticipates however, that its
investment in facilities and equipment will increase in the future, due to the
Company's desire to consolidate its manufacturing, administrative and research
and development facilities and the need to increase the automation of its
electrode manufacturing processes to meet higher expected sales volumes. The
Company's expenditures for equipment and furniture were $156,000, $316,000 and
$231,000 in each of the fiscal years ended June 30, 1995, 1996 and 1997,
respectively.
 
     During fiscal 1997, the Company generated $255,000 in cash from the private
placement of its Common Shares. During fiscal 1996, the Company generated $1.0
million ($892,000, net of related expenses) in cash from the sale of a 20%
equity interest in Dermion to Novartis. See "Transactions Related to the
Offering."
 
     The Company expects to continue to incur substantial costs associated with
the expansion of its research and development activities, including clinical
trials, development of a dedicated sales force and consolidating and equipping
its facilities. The Company anticipates that the net proceeds of the Offering,
together with existing cash balances and cash generated from operations
(including funding from Novartis) will be sufficient to fund the operations of
the Company for approximately the next two years. However, the Company may be
required or elect to raise additional capital before that time. The Company's
actual capital requirements will
 
                                       29
<PAGE>   31
 
depend on many factors, some of which are outside the Company's control. See
"Risk Factors -- Future Capital Needs; Uncertainty of Additional Funding" and
"Use of Proceeds."
 
     Concurrently with the closing of the Offering, Elan has agreed to purchase
the Elan Shares directly from the Company, in private placement transactions,
for approximately $15.3 million. Simultaneously with Elan's purchase of such
shares, the Company will repay the Elan Notes, including interest thereon. See
"Transactions Related to the Offering," "Certain Transactions" and Note 7 of the
Notes to Consolidated Financial Statements.
 
DISCONTINUED OPERATIONS
 
     Prior to January 1997, the Company provided state-of-the-art prosthetics
products to amputees throughout the United States, Canada and Western Europe
through its Motion Control division. Motion Control's principal products were
the Utah Artificial Arm and the ProControl II, advanced myolectric prostheses
for above and below the elbow amputees.
 
     In December 1996, the Company sold the assets of the Motion Control
division for $1.0 million and granted the purchaser an exclusive, worldwide
license and sublicense to the patents, trademarks, know-how and other
intellectual property of the Company relating to the Motion Control products.
Under the terms of that sublicense agreement, the Company will receive license
fees and royalties on future sales of the Motion Control products. There was no
significant gain or loss recognized on the sale. The results of operations of
the Motion Control division, exclusive of any corporate allocations, are
reported as discontinued operations in the consolidated financial statements for
all periods presented. See Note 4 of the Notes to the Consolidated Financial
Statements.

INTRODUCTION
 
     The Company develops, manufactures and commercializes controllable drug
delivery systems using iontophoretic technology. Iontophoresis is a non-invasive
method of enhancing and controlling the transport of water-soluble ionic drugs
into and through the skin using a low level electrical current. The Company's
proprietary iontophoretic drug delivery systems allow rapid onset and cessation
of therapeutic action, as well as programmable dose control. The systems enable
caregivers and patients to control the onset of drug effectiveness and maintain,
reduce or cease drug administration once a desired therapeutic effect is
observed. The programming feature also enables caregivers to customize dosing
patterns to meet each patient's specific needs. The Company is developing
systems designed to enable patient monitoring and control. The flexibility of
the Company's proprietary systems provides therapeutic control not possible with
many alternative drug delivery methods, including oral tablets and capsules,
injections, inhalants and passive transdermal patches. The Company's systems may
also increase bioavailability, safety and patient comfort.
 
     The Company markets two products, an iontophoretic system used to deliver
Dexamethasone and an iontophoretic system used to deliver Iontocaine. Since it
was introduced in 1979, the Company's system for the delivery of Dexamethasone
has been used primarily by physical therapists and athletic trainers in over 10
million patient applications for the treatment of acute local inflammatory
conditions such as tendonitis, tennis elbow and carpal tunnel syndrome. More
than 8 million of these applications have occurred since 1990, when the Company
introduced its present family of gel electrodes for use with its microprocessor
controlled dose controller. The Company's system to deliver Iontocaine provides
needle-free, long-lasting local dermal anesthesia up to six times more rapidly
and up to three times deeper than can be achieved using topical anesthetic
creams. The Company is initially marketing its Iontocaine product under the
brand name Numby Stuff in pediatric hospitals in the United States. The Company
is also developing a number of iontophoretic drug delivery systems for other
indications, including conscious sedation, tocolysis, post operative and chronic
pain control, and osteoporosis.
 
BACKGROUND ON DRUG DELIVERY SYSTEMS
 
     A wide variety of drug delivery methods is currently available in the
market, although not all drugs can be delivered by all routes of administration.
For certain applications, there are clinical benefits in providing rapid onset
of therapeutic action and the minimum drug dosage necessary to achieve the
desired effect. In all applications, drug delivery should be convenient, cost
effective and as non-invasive as possible.
 
     Conventional Oral Methods. Conventional oral drug dosage forms, such as
pills and capsules, are the most common types of drug delivery. These methods
offer ease of administration and low cost-per-use, but their application is
often limited by inconvenient dosage intervals and less than optimal
bioavailability (due to degradation of the drug in the gastro intestinal tract
("GI tract") and the liver) and efficacy. In addition, conventional oral dosage
forms often produce higher initial drug levels than are required to achieve the
desired therapeutic effects, thereby increasing the risk of side effects and
lower than therapeutically optimal levels of the drug as it is metabolized and
cleared from the body. More frequent administration of lower doses can sometimes
mitigate this problem, but can also increase cost, inconvenience and patient
noncompliance.
 
     Injection Methods. Injectable drug dosage forms generally provide rapid
onset of action and offer many of the same advantages as conventional oral drug
dosage methods. Like conventional oral dosage forms, however, they often produce
higher initial drug levels than are required to achieve the desired therapeutic
effect, thereby increasing risk of side effects. Injectable drug delivery
methods require caregiver administration and have the added disadvantage of
using needles as a delivery path into the body, raising the possibility of
needle stick injuries, as well as risk of infection to the caregiver and the
patient. The use of needles also increases patient anxiety due to the pain of
injection.
 
     Controlled Release Methods. Controlled release drug delivery systems
attempt to overcome many of the limitations inherent in conventional drug
delivery methods by maintaining a more consistent and appropriate drug level in
the bloodstream. Sustained release oral dosage forms are designed to release the
active
 
                                       31
<PAGE>   33
 
ingredients of the drug into the body at either a predetermined point in time or
at a predetermined rate over an extended period of time, but they generally do
not provide rapid onset of action and may not achieve optimal bioavailability.
Passive transdermal patches allow absorption of drugs through the skin and
generally provide a convenient method of administering drugs at a steady rate
over an extended period of time, but onset of action may take hours after
application and absorption of the drug may continue for hours after the patch is
removed, which can increase side effects. Additionally, because human skin is an
effective barrier, most drug formulations will not passively permeate the skin
in therapeutic quantities. Continuous infusion pumps introduce drugs directly
into the body, thereby providing rapid onset of action, and may offer variable
controlled dosing. Infusion therapy requires insertion of a needle, however,
and, therefore, can be painful and threatening to the patient. The use of
infusion pumps also increases the risk of infection and generally requires
medical professionals for safe administration, which may significantly increase
costs.
 
     Pulmonary and Nasal Methods. Both pulmonary (inhalation) delivery and nasal
sprays are designed to provide rapid onset of action or to deliver drugs that
are not orally bioavailable. Pulmonary delivery has the disadvantage of variable
drug amounts reaching the alveoli of the lungs, therefore making it difficult to
control the bioavailability of the dose. Nasal sprays can cause irritation in
some patients and can be difficult to administer in variable intranasal
conditions. In addition, the dose of the product cannot be controlled by the
patient over a period of time, and patients and caregivers may have difficulty
maintaining the desired therapeutic effect.
 
     Other. Many existing and emerging pharmaceutical compounds, such as
biotechnology-derived oligonucleotides, peptides and other macromolecular drugs,
cannot be effectively administered by traditional non-invasive methods and are,
therefore, administered only by injection or infusion. Oral delivery of such
molecules is generally inefficient due to the rapid breakdown of the molecules
during digestion and the natural impermeability of the GI tract to larger
molecules. The skin is even less permeable to macromolecules than the GI tract,
which the Company believes is the primary reason passive transdermal delivery of
those molecules using patch technology has not been successful to date.
 
IONTOPHORETIC DRUG DELIVERY AND ITS ADVANTAGES
 
     Iontophoretic drug delivery systems are designed to overcome many of the
limitations associated with many other drug delivery methods. Iontophoresis is
an active method of transdermal drug delivery in which water-soluble, ionized
(electrically charged) drugs are transported through the skin for local or
systemic therapeutic applications by applying a low level, external electrical
current. The amount of drug delivered through the skin is proportional to the
total electrical charge applied (which is a function of time and current).
Therefore, it is possible to program the system's electrical current levels to
control more precisely the desired drug dose, delivery rate and the pattern of
delivery.
 
     Iontophoretic drug delivery systems are generally comprised of a power
supply which is used to control drug dose (the "dose controller") and a pair of
electrodes, one containing the drug and one serving as a grounding electrode to
complete the electrical circuit through the skin. The drug electrode consists of
a matrix which contains the drug solution, a conductive element which
distributes the electric current through the drug matrix, an electrical
connector that links the electrode to the dose controller, and an adhesive layer
that attaches the electrode to the body. The grounding electrode consists of
similar components, but without the drug solution. The drug delivery electrode
is applied to the patient's skin at a local treatment site (such as for joint or
tendon soreness or to induce local dermal anesthesia), or at any suitable site
on the body for systemic drug delivery. The grounding electrode is applied to
the skin a short distance away from the drug electrode. As is shown in the
following illustration, when an electric current with the same positive or
negative electric charge as the drug is applied to the drug electrode, the drug
is repelled from the electrode and into the skin in the same way as like poles
of two magnets repel each other. Although the Company's currently marketed
products consist of discrete components, the Company has begun the development
of more advanced systems which integrate all components in a single miniaturized
patch.
 
                                       32

                                      LOGO
 
     The Company believes that, for certain applications, iontophoretic drug
delivery systems may offer several advantages over other drug delivery methods,
including:
 
     Broad Applicability. A substantial number of the drugs on the market and in
development today are, the Company believes, ionic and water-soluble and,
therefore, may be amenable to delivery by iontophoresis. In addition,
iontophoretic drug delivery systems may be applicable to a significantly broader
range of pharmaceutical compounds, including larger drug molecules such as
peptides and oligonucleotides, than passive transdermal drug delivery methods.
 
     Increased Convenience and Compliance. Iontophoretic drug delivery systems
are easy to use and offer simple, needle-free administration that eliminates the
inconvenience of frequent dosing, and may, if successfully developed and
approved by applicable regulatory authorities, permit patient
self-administration.
 
     Programmable Control of Drug Delivery. The rate, timing and pattern of drug
delivery using an iontophoretic drug delivery system can be controlled by
varying the electrical current applied to the system's electrodes. The benefits
of this ability to control the drug's delivery include the following:
 
     -  Rapid Onset of Action -- The speed with which a drug delivery system can
        provide efficacious blood levels of the target drug determines the onset
        of therapeutic action. Iontophoretic drug delivery systems allow many
        drugs to pass directly through the skin into underlying tissue and the
        bloodstream at a rate that is significantly more rapid than oral or
        passive transdermal delivery methods. Research has shown that certain
        drugs can be delivered by iontophoresis more than 10 to 1,000 times
        faster than drug delivery by passive transdermal patches.
 
     -  Rapid Cessation of Administration -- In certain applications, it is
        desirable that drug delivery cease once the desired effect has been
        obtained. Iontophoretic drug delivery systems allow rapid cessation of
        drug delivery since absorption of water-soluble drugs from the skin into
        bloodstream ceases rapidly after the current is turned off or the drug
        electrode is removed from the skin.
 
     -  Variable Dose Control -- Iontophoretic drug delivery systems may be
        designed to offer precision controlled dosing that can be customized for
        desired therapeutic profiles or for individual patient needs, including
        baseline and/or bolus dosing.
 
     -  Patient Controlled Dosing -- Iontophoretic drug delivery systems may be
        designed to offer active patient control or intervention in the dosing
        regimen, while at the same time incorporating programmed lock-outs for
        added safety and dose monitoring capability.
 
     -  Dose-to-Effect -- Iontophoretic drug delivery systems allow caregivers
        or patients to monitor the onset of drug effectiveness and maintain,
        progressively reduce or cease drug administration once a desired
        therapeutic effect is observed.

THE COMPANY'S IONTOPHORETIC SYSTEMS
 
     While the fundamentals of iontophoresis have been understood for decades,
the technology has become commercially practicable as a method for delivering
drugs only recently as a result of advances in electronics, materials science
and electrochemistry. These advances have led to the development of more
efficient and adaptable drug containment electrodes and more reliable, compact
and programmable dose controllers. The Company has developed iontophoretic drug
delivery systems which incorporate dose controllers and electrodes that have
enhanced performance characteristics, which the Company believes are adaptable
to a number of clinical settings and therapeutic applications, and which the
Company believes are cost effective in a number of therapeutic applications. The
Company's current iontophoretic drug delivery systems are not designed to
facilitate patient self-administration, but drug delivery systems currently
being developed by the Company may allow patients significant control over the
administration of certain drugs.
 
     In March 1997, the Company entered into an agreement with Elan to obtain an
exclusive, worldwide license to the commercial exploitation of certain
technology developed by Elan in the field of iontophoretic drug delivery and
certain other electro-transport fields. The acquisition of the Elan technology
is intended to speed the development and commercialization of products using the
combined technologies, including the miniaturized integrated, wearable systems
currently under development by the Company. The Company also believes its
competitive position in relation to other companies engaged in the development
of iontophoretic drug delivery systems has been significantly enhanced by Elan's
broad base of United States and foreign patents, in-depth body of in vitro drug
transport data and in vivo animal and human clinical data, in addition to other
proprietary know-how.
 
     Dose Controllers. The Company's dose controllers generate the low-level
electrical current needed for iontophoretic drug delivery. The Company presently
markets a compact, fully portable dose controller, the Phoresor, that offers
durable microprocessor control, enhanced user interface, versatile programmable
dosing capability, autocalculating treatment time (based on electrical current
settings and selected dose) and constant current output (by automatically
adjusting voltage to compensate for variations in the electrical resistance of
the skin). The Phoresor incorporates a microprocessor, other electronic
circuitry, on-board software that monitors and controls the rate of current
flow, and an easy-to-use control panel. The Company has also developed, and
anticipates marketing in the near future, a new dose controller for specific use
with its pediatric local dermal anesthetic product. See "Business -- Products
and Products Under Development -- Local Dermal Anesthesia." The Company's next
generation of dose controllers, both stand-alone and wearable miniaturized
versions, are being designed to include many of the same features as the
Company's current dose controllers. Depending on the therapeutic application,
the new generation dose controllers may be designed to allow bolus dosing
capability and programming (using a physician's or pharmacist's key) to adjust
dosing to match desired delivery profiles or patterns.
 
     In a clinical setting for short treatment durations, the battery and dose
controller are housed in a discrete, reusable, table-top unit connected to a
pair of disposable, single-use electrodes to which drug solution is added
immediately prior to application to the patient. This technology is used in the
Company's current products. For longer term or chronic applications or
patient-administered therapy outside the clinical setting, the Company is
developing iontophoretic drug delivery systems in which the battery, dose
controller and electrodes will be combined in a small patch applied to the skin
as a single, integrated unit. The electronic components may be reusable, with
replaceable or rechargeable batteries and single-use, disposable drug and
grounding electrodes, or the entire unit may be disposable after a single use.
The drug may be added to the electrode drug pad during manufacturing, or may be
stored separately in the system and introduced into the drug containment pad
immediately before use by means of proprietary, integrated hydration devices
developed by the Company.
 
     Electrodes. Electrode design is critical to successful delivery of a drug
by iontophoresis. The Company's electrodes incorporate patented and proprietary
design innovations which the Company believes offer significant advantages to
both patients and health care providers. The Company's proprietary electrode
technology includes patented polymer hydrogels which absorb drug solutions in
seconds, becoming soft and pliable so as to conform better to the body and to be
comfortable to the patient. The Company's electrode
 
                                       34
<PAGE>   36
 
technology also employs special silver and silver chloride inks to distribute
electric current evenly from the dose controller to the electrodes and control
possible changes in acidity and alkalinity (pH changes) which can occur during
iontophoresis, thereby preventing possible drug instability or unacceptable skin
irritation.
 
BUSINESS STRATEGY
 
     The Company's primary business goal is to establish its proprietary
iontophoretic drug delivery systems as a preferred, cost effective means of
delivering a wide range of drugs. To achieve this goal, the Company uses its
multi-disciplinary expertise in pharmacology and drug formulation, regulatory
and product testing, microelectronics, electrochemistry, polymer chemistry and
adhesives. The Company's strategy for achieving this goal includes the following
principal elements:
 
     Develop Systems for Off-Patent Drugs. The Company intends to continue the
independent development of proprietary iontophoretic drug delivery systems for
off-patent drugs with known safety and efficacy and for which the Company
believes its drug delivery technology may be cost competitive with and offer
advantages over other drug delivery methods. The Company believes that, by
developing proprietary products based on currently approved off-patent drugs,
rather than new chemical entities ("NCEs"), it can reduce regulatory and
development risks and shorten the product development cycle for certain
products. See "Risk Factors -- Uncertainty of Government Regulation" and
"Business -- Government Regulation."
 
     Enter into Collaborative Relationships. In order to gain access to NCEs and
other proprietary drugs, and to reduce the costs and risks associated with the
development of iontophoretic drug delivery systems for such compounds, the
Company intends to enter into collaborative relationships with pharmaceutical
and other biotechnology companies whose drugs could benefit from the Company's
iontophoretic drug delivery technology. The Company has entered into a
collaborative development agreement with Novartis for the purpose of evaluating
the potential for the development of iontophoretic drug delivery systems for a
number of Novartis compounds for several therapeutic applications. In
collaboration with Novartis, the Company is currently developing an
iontophoretic drug delivery system to deliver a drug for the treatment of
osteoporosis.
 
     Increase Market Penetration of Existing Products. In order to leverage the
capabilities of its direct and dealer sales forces, the Company intends to enter
into collaborative sales and marketing relationships with other parties that
have specific expertise in markets targeted by the Company. In general, the
Company intends to use collaborative sales and marketing relationships in the
sale and distribution of its products to the general physician, international
and specialty markets, including the podiatric, orthopedic and chiropractic
markets.
 
     In addition, the Company is actively seeking to expand the commercial
potential of its local anesthesia and acute inflammation products by pursuing
new applications. The Company will continue to conduct (i) marketing studies
aimed at expanding the use of its delivery system for Iontocaine to a broader
range of procedures and (ii) clinical trials to further establish the safety and
efficacy of iontophoresis for the treatment of local inflammation using
Dexamathasone or for use in other specific procedures.
 
     Broaden Technology Platform. The Company intends to enhance its proprietary
iontophoretic technology base principally through internal research and
development. The Company will also pursue additional iontophoretic and other
complementary products and technologies owned or developed by third parties, on
a case-by-case basis, through in-licensing or acquisition.
 
     Control Product Manufacturing Processes. The Company intends to maintain
control over the manufacture of its electrode kits in order to retain control
over the quality of its products and capture a larger portion of the product
revenue stream when third parties are involved in the marketing of the product.
 
PRODUCTS AND PRODUCTS UNDER DEVELOPMENT
 
     The Company currently has product development programs at various stages of
development for acute local inflammation, local dermal anesthesia, remission of
pre-term labor, conscious sedation, pain control and osteoporosis. The following

  ACUTE LOCAL INFLAMMATION
 
     Acute local inflammatory conditions resulting from exercise, sports
injuries, trauma or repetitive motion disorders are among the leading types of
injuries occurring in the workplace and among physically active adults. The most
common of these injuries include tendonitis, bursitis, carpal tunnel syndrome
and epicondylitis (tennis elbow). Generally, patients suffering from these
conditions are initially treated with oral nonsteroidal anti-inflammatory drugs
("NSAIDS") for a period of up to fourteen days. Although steroid injections are
generally more effective than NSAIDS, medical professionals usually avoid
steroid injections in all but severe cases because of the negative side effects
that can accompany bolus needle injections of corticosteroids into an inflamed
joint or tendon, including risk of infection, tissue distortion, tendon
weakening and tendon rupture. If patients do not respond to treatment with
NSAIDS, the physician generally has two options -- refer the patient to a
physical therapist, or proceed with injection of anti-inflammatory steroids such
as Dexamethasone. Based on market data with respect to the number of
corticosteroid injections for acute inflammation as well as data gathered by the
Company in a survey it conducted of 54 physical therapy clinics around the
United States with respect to the number of patients that visit physical therapy
clinics for acute inflammation, the Company estimates that the total potential
retail market in the United States for the sale of iontophoretic drug delivery
systems to clinicians to treat acute local inflammatory conditions is in excess
of $400 million. In addition, the Company estimates that current total retail
sales into this market by the Company and its competitors are under $30 million.
 
     The Company believes iontophoretic delivery of Dexamethasone provides
significant advantages over other current treatment regimens for acute local
inflammation. The Company believes iontophoresis eliminates many of the risks
and inconvenience associated with bolus steroid injections, avoids the systemic
side effects of oral steroids and eliminates the significant incidence of GI
tract side effects of orally
 
                                       36
<PAGE>   38
 
administered NSAIDS. The Company believes iontophoresis also increases
therapeutic efficacy by bypassing metabolism by the liver, by reducing the
possibility of overdosing, and by providing localized delivery at the target
site without trauma. As a result, the Company believes that it may be
advantageous to introduce the iontophoretic delivery of Dexamethasone into the
initial treatment regimen for acute local inflammation. The Company believes
that earlier treatment with Dexamethasone has the potential to significantly
increase the rate of patient recovery and, in doing so, reduce the overall cost
of patient treatment.
 
     Commercial Products. The Company pioneered the commercial introduction of
an iontophoretic drug delivery system for the treatment of local acute
inflammation in 1979. The product is used principally by physical therapists
(under a doctor's prescription) and has been administered in over 10 million
patient treatments for the iontophoretic delivery of Dexamethasone. More than 8
million of these treatments occurred since 1990, when advancements in electrode
technology made by the Company led to the introduction of its present family of
gel electrodes for use with its microprocessor controlled dose controller. The
Company's system for the delivery of Dexamethasone is also used by athletic
trainers and physical therapists serving a number of professional athletes,
including professional golfers and tennis players, men's and women's olympic ski
teams and professional football, basketball and hockey teams. The Company
believes that iontophoretic drug delivery systems are accepted in the
rehabilitation marketplace due to their ease of use, non-invasiveness,
recognized efficacy and lack of side effects.
 
     The Company currently markets four different electrode kits in three
different configurations and continues to develop additional electrode kits and
configurations for application in different segments of the acute local
inflammation market. The Company's existing electrode kits, as well as those it
has under development, are designed to be user friendly and to offer clinicians
a broad range of electrode sizes, formats, configurations and price ranges.
 
     Products Under Development. Currently, due to limited labeling of
Dexamethasone, neither the Company nor its competitors has the requisite
regulatory approval to specifically promote the use of iontophoretic drug
delivery systems for the delivery of Dexamethasone. The Company believes that
its inability to do so limits its ability to market its system, particularly to
the physician market. The Company further believes that to market iontophoretic
drug delivery systems for a specific drug and therapeutic indication the FDA
requires that each new drug/device combination be approved through an NDA
process. Therefore, in order to expand the Company's sales of its delivery
systems into the physician market as a first line treatment for acute local
inflammation, the Company has filed an investigational new drug ("IND")
application with the FDA under which it intends to establish the safety and
efficacy of its current drug delivery system for Dexamethasone. Upon completion
of the protocol design, the Company intends to select appropriate clinical sites
and initiate clinical studies in support of filing an NDA (or an appropriate
drug/ device combination marketing application seeking FDA approval to label a
formulation of Dexamethasone for use with the Company's Phoresor for treatment
of acute local inflammatory conditions. The Company believes that because of the
known safety and efficacy profile of Dexamethasone and the acute nature of the
conditions to be treated in these studies, the duration of the studies and the
required follow-up periods may not be as extensive as would be required for a
NCE. See "Risk Factors -- Uncertainty of Government Regulation."
 
     The Company believes the approval of an NDA (if obtained) will allow the
Company to actively promote the iontophoretic delivery of Dexamethasone to
general and family practice physicians, orthopedists, neurologists and sports
and industrial medicine clinics. The Company believes this could significantly
enhance the Company's ability to establish its delivery system for Dexamethasone
as a primary treatment option for acute local inflammatory conditions. The
Company also believes that, with an approved NDA to complement its device, many
physicians who refer their patients for physical therapy will do so with a
specific prescription for iontophoresis using the Company's proprietary drug
delivery system.
 
  LOCAL DERMAL ANESTHESIA
 
     Medical care providers have long recognized the importance of the
management of pain, including pain associated with certain minimally invasive
medical procedures such as needle injections; venous access (including
phlebotomies and intravenous catherizations); lumbar punctures; and local
dermatological,
 
                                       37
<PAGE>   39
 
gynecological and urological procedures such as wart and mole removal, LOOP/LETZ
procedures, biopsies (including fine needle, punch, excisional, shave and
cervical biopsies), Mohs procedures and vasectomies. To address this concern,
local dermal anesthetics are widely used in medical practice.
 
     The primary means of administering local dermal anesthetics is by needle
injection, which has the benefit of being fast, effective and long lasting.
However, the fear and pain associated with the needle stick, especially on the
extremities or on other sensitive areas such as the face, vulva and cervix is
compounded by the sting associated with virtually all injectable local
anesthetics. These factors increase patient discomfort and anxiety. In addition,
the local tissue distortion which typically accompanies injections may cause
procedural difficulty for the physician. New topical analgesic formulations have
recently been introduced into the market and are gaining widespread acceptance,
especially in pediatric hospitals and clinics and in pediatric dermatology.
These topical formulations avoid many of the pitfalls of anesthetic injections,
but they generally require significant advance preparation since they require
one to two hours to obtain anesthesia. Even when topical formulations are given
adequate time to achieve anesthesia, they anesthetize only to a maximum depth of
3 to 5 mm. The time required to achieve therapeutic anesthesia and the depth of
anesthesia make these formulations less suitable or impractical for many
potential applications. The Company believes that the growing interest in these
products, in spite of their clinical limitations, is a positive indication of
the market's desire for an effective, needle-free local dermal anesthetic.
 
     Commercial Products. The Company's Iontocaine brand of lidocaine HCl 2% and
epinephrine 1:100,000 is FDA approved under an NDA and is specifically labeled
for use with the Company's Phoresor and its proprietary, single use, disposable
electrode kits. The Iontocaine delivery system was shown to be safe and
effective in double blinded, placebo controlled, randomized studies in over 400
adult and pediatric patients. Based on these studies, the Company filed an NDA
with the FDA and received labeling to use the system for all procedures
requiring local dermal anesthesia.
 
     Using the Company's product, clinicians can administer needle-free, long
lasting (up to two hours) local dermal anesthesia up to a depth of 10 mm in
approximately ten minutes. The Company believes the ability to provide painless
local dermal anesthesia up to three times deeper than topical formulations, in
85% less time, could make the Company's products a preferred drug delivery
method for many existing applications where topical anesthetic creams are
currently employed, and that the product will provide a means of painlessly
inducing local dermal anesthesia for a broader range of medical procedures where
the use of such creams is not practical.
 
     A leading concern among patients, parents and health care professionals is
the control of pain in the practice of children's medicine, including the pain
associated with needle insertions. With the growing acceptance of topical
anesthetic creams in the pediatric hospital setting, the Company believes there
is a large potential market for an iontophoretic drug delivery system targeted
toward pediatrics. Accordingly, the Company has focused its initial local dermal
anesthesia product launch into the pediatric market under the brand name Numby
Stuff. Numby Stuff, which the Company launched in January of 1997, currently
consists of the Phoresor, the Company's line of proprietary, single use,
disposable electrode kits and Iontocaine, all in a brightly colored, child
friendly product package. Numby Stuff is currently being used to induce local
dermal anesthesia prior to pediatric intravenous starts, blood draws and other
invasive procedures, and the Company believes it provides a cost effective
alternative to the leading topical product. The Company estimates that pediatric
intravenous starts, blood draws and other invasive procedures are performed more
than 20 million times in the United States each year.
 
   
     Numby Stuff was recently reviewed by the new product review committee of
the Alliance of Children's Hospitals ("ACH"), a subsidiary of the Child Health
Investment Corporation ("CHIC"), a consortium of 36 of the leading free standing
children's hospitals in the United States. In December 1996, the committee
granted Numby Stuff ACH's "Seal of Acceptance." The Seal of Acceptance was
granted by ACH in recognition of the significant therapeutic benefits ACH
believes Numby Stuff offers in the practice of pediatric medicine. Numby Stuff
is one of only 24 products used in pediatric hospitals that bear the ACH Seal of
Acceptance. In order to use the Seal of Acceptance to promote Numby Stuff, the
Company was required to make royalty payments to ACH. The Company satisfied
ACH's royalty requirements by
    
 
                                       38
<PAGE>   40
 
   
issuing ACH warrants to acquire, through December 1, 2003, 44,791 Common Shares
at an exercise price of $8.88 per share. In connection with obtaining the rights
to use the ACH Seal of Acceptance, and at CHIC's request, the Company sold CHIC
37,202 Common Shares for $250,000. CHIC maintains a venture fund to make
investments in medical products companies. In connection with the awarding of
the Seal of Acceptance, ACH will provide continued support and endorsement for
Numby Stuff and, although ACH's member hospitals are not required to purchase
any product awarded ACH's Seal of Acceptance, ACH will assist the Company in
introducing the product to pharmacy directors and other clinical specialties
within its member hospitals.
    
 
     Products Under Development. The Company has developed a working prototype
of a preprogrammed, fixed dose, dose controller with push-button operation for
use as part of the Numby Stuff product. The Company is currently working with
its third party supplier to develop manufacturing specifications for the new
dose controller, and expects to initiate manufacturing and marketing of the dose
controller in fiscal 1998. The Company believes that the new dose controller's
anticipated pricing and simplified operation will further enhance the
marketability and use of Numby Stuff.
 
     In order to achieve greater market acceptance of its Iontocaine product in
pediatric markets, the Company supports evaluations conducted by doctors and
other medical personnel for the use of its anesthetic product prior to a wide
variety of painful medical procedures. The Company is currently conducting or
planning two studies evaluating the use of Numby Stuff prior to lumbar punctures
and circumcisions in pediatric patients. Depending on the results of these
studies, the Company may develop new electrode kits which specifically address
these opportunities. The Company also believes, in addition to the pediatric
market, the adult hospital market represents additional opportunities for
growth. The Company believes that it could service the adult hospital market by
making minor modifications in its product image and by using its existing sales
force. For example, according to published studies, there are over 250 million
venous catheters inserted each year, of which a large percentage are inserted in
adult patients.
 
     The Company also believes Iontocaine, together with the Phoresor and
adaptations of its existing electrode designs, can be successfully used to
induce effective local dermal or mucosal anesthesia prior to certain
gynecological procedures. The Company believes the effective, rapid, painless,
needle-free anesthesia provided by the Company's drug delivery technology would
increase patient comfort. In general, the Company believes the promotion of the
Company's systems for use in connection with gynecological procedures involving
mucosal membranes would require additional FDA approval, most likely in the form
of a supplement to the Company's existing Iontocaine NDA. The Company does not
believe gynecological procedures involving the vulva would require additional
FDA approval. The Company has performed preliminary studies which indicate that
its anesthetic system may significantly reduce or eliminate the pain of vulvar
biopsies. The Company has already tested prototype electrodes which are
specifically designed for this application. There are approximately 50 million
pap smears performed each year in the United States, of which the Company
estimates approximately 2.5 million require follow-up procedures that could
benefit from non-invasive local dermal anesthesia. The majority of these
procedures are performed by a relatively small number of gynecologists who are
mainly located in high density population areas that are also the major centers
for the Company's pediatric marketing efforts. See "Risk Factors -- Uncertainty
of Government Regulation."
 
  REMISSION OF PRE-TERM LABOR
 
     Pre-term birth is a leading cause of neonatal morbidity and mortality. Each
year in the United States alone, 10% of all births are premature resulting in
more than 400,000 babies being born before completing 37 weeks of gestation. The
cost of neonatal intensive care required for pre-term babies exceeds $5.0
billion a year in the United States. The Company believes prolonging pregnancies
threatened by pre-term delivery by even a few days may result in improved
clinical outcomes, which could represent an important opportunity for
significant medical, economic and social benefits.
 
     The Company estimates that each year a significant number of patients in
the United States who are at risk for or experience pre-term labor and pre-term
birth are placed on one or more forms of tocolytic drug
 
                                       39
<PAGE>   41
 
therapy. Tocolysis is the clinical term for the remission of labor. Although
many of these therapies are not specifically FDA approved, the medical
literature indicates that they have been successful in a large number of
patients. The Company believes the number of patients placed on various
tocolytic drug therapies will rise with the increased use of ambulatory external
tocodynamometers and the advance of other new diagnostic techniques and products
used to identify patients at risk. These advances in diagnostics should aid in
identifying asymptomatic pregnant women.
 
     A typical therapeutic program for a pregnant woman who is experiencing
acute episodes of pre-term labor consists of intravenous ("IV") infusions of
magnesium sulfate in the hospital. After a period of 12 to 24 hours of
successful tocolysis, the patient is then switched to oral terbutaline sulfate
tablets and released. Usually, after two to three weeks, the therapeutic effects
of oral terbutaline are lost and the patient must be readmitted to the hospital
to begin the treatment cycle again. If symptoms persist, the patient is often
placed on an injectable form of terbutaline sulfate by means of a subcutaneous
infusion pump. Although not approved by the FDA for this indication,
subcutaneous infusion terbutaline therapy has been found to be effective in
controlling pre-term labor and avoiding the loss of therapeutic efficacy
experienced with oral dosing. Subcutaneous infusion terbutaline therapy can last
for a over a month, with a mean treatment period of approximately three weeks,
and costs approximately $1,500 to $2,000 per week. Those costs include pump
rental, drugs, disposable infusion kits and central monitoring and home visits
by a skilled medical professional.
 
     Products Under Development. The Company is evaluating a system for
delivering terbutaline using iontophoresis. Based on in vitro feasibility
testing it has conducted, the Company believes terbutaline may be delivered by
iontophoresis in therapeutic quantities. The Company intends to seek NDA
approval for the delivery of terbutaline for remission and pre-term labor using
its iontophoretic drug delivery system. It has prepared a protocol for a Phase I
blood level study, has received Institutional Review Board approval and expects
to initiate that study by the end of 1997. The Company believes that an
iontophoretic drug delivery system for terbutaline could offer an alternative
treatment regimen to oral terbutaline therapies with all of the benefits of home
infusion therapy. The Company also believes an iontophoretic system may have
substantial advantages over subcutaneous infusion therapy, including being less
expensive to produce and service than standard infusion therapy devices,
potentially providing greater patient comfort (since the electrodes could be
placed at various sites on the body) and being non-invasive, thereby eliminating
the risk of infection and reducing the need for frequent intervention by a
skilled medical professional.
 
     Since the general pharmacology and toxicology of terbutaline are well
known, and because the Company believes this is an area of significant interest
within both the FDA and the medical community, the Company believes that, if its
Phase I blood level studies are successful, it may be able to progress more
rapidly into Phase III studies in at-risk, pregnant women than would be possible
for an NCE. Due to the nature of the condition being treated, the Company
believes the clinical trials should be of relatively short duration and will
have a clearly defined endpoint. See "Risk Factors -- Uncertainty of Government
Regulation."
 
  CONSCIOUS SEDATION
 
     Many patients, especially children, experience extreme anxiety before the
start of invasive or painful medical procedures, during stressful diagnostic
tests such as endoscopies, magnetic resonance imaging, and CT scans, and before
and during certain dental and emergency room procedures. Invasive methods of
premedication and sedation, such as intramuscular ("IM") injections or IV
administration of analgesics or sedatives, can cause anxiety. Clinicians have
long sought alternative, non-invasive methods of premedication. Despite the
absence of approved labeling for safety and efficacy for oral administration,
clinicians widely use injectable drugs and drug combinations mixed with flavored
syrups for off-label oral administration in children. Since 1994, clinicians
have also been able to use fentanyl for conscious sedation using an oral
transmucosal delivery system. Oral administration may require up to five times
the amount of drug recommended for injection because of decreased
bioavailability, but is used because the alternative of IV or IM injections are
counterproductive to the goal of relieving anxiety. Based on market data, the
Company estimates that annual worldwide sales of the top two products used for
conscious sedation are approximately $950 million.
 
                                       40
<PAGE>   42
 
     Products Under Development. The safety and efficacy of fentanyl as a drug
to induce conscious sedation are well known. Data from two human blood level
studies with fentanyl conducted by the Company and a former collaborative
partner show that it may be possible for therapeutic quantities of fentanyl to
be delivered by iontophoresis. Therefore, the Company believes it could
represent a viable drug for inducing conscious sedation using the Company's
iontophoretic drug delivery systems. As a result of an existing contractual
obligation with its former collaborative partner, the Company has agreed not to
pursue development of a fentanyl conscious sedation product until the second
quarter of calendar year 1998. Further, the Company's ability to market a
product in the United States using fentanyl may also be limited by certain
litigation now before the PTO. See "Risk Factors -- Dependence on Patents and
Proprietary Technology" and "Business -- Collaborative Relationships and
Licenses."
 
  PAIN MANAGEMENT
 
     The Company estimates that of the 24 million surgeries performed each year
in the United States, 75%, or 18 million, result in moderate to severe post
operative pain. In addition, there are currently 9.1 million cancer patients in
the United States. Each year roughly 6.6 million patients with cancer are
treated for pain and of these 65% to 80%, experience moderate to severe pain. In
recent years, there has been a growing awareness that many patients, especially
the terminally ill, do not receive adequate analgesic therapy for their pain.
Sales of prescription narcotics in the United States to treat pain were
approximately $1.0 billion in 1996 and according to market reports the market is
estimated to grow at a rate of approximately 10.5% per year. Factors
contributing to this growth rate include more relaxed policies for narcotic
administration and the introduction of drug delivery systems that make
administration safer, more controllable and convenient.
 
     Morphine is the most commonly prescribed drug for the management of severe
pain in critically ill patients in the United States. Morphine and hydromorphone
are the most widely used parenteral pain medications for home use because they
are relatively safe, effective and have relatively short half lives.
Hydromorphone is a more potent, highly soluble analog of morphine, which is the
standard against which other analgesics are generally measured.
 
     The Company believes that iontophoretic delivery systems for narcotic
analgesics for the treatment of post operative and chronic pain control could
offer significant benefits over existing methods of delivery, including infusion
pumps, transdermal patches and transmucosal products. To provide effective pain
relief, a morphine injection is generally administered every four hours.
Repeated injection or continuous infusion of morphine is expensive because the
methods of administration consume substantial hospital staff time or require
daily visits by a health care provider to a patient receiving home infusion
therapy. An iontophoretic system has the potential to offer all of the benefits
of an infusion pump, including the ability to closely match the delivery profile
with rapid onset and cessation of action characteristics and to provide control
of baseline delivery with bolus dose capability for acute episodes of pain, but
without the need to use needles. The Company believes an iontophoretic delivery
system for pain management may also be more convenient and less expensive, since
the rental of costly infusion pumps and intervention by a skilled medical
professional may not be required. Passive transdermal patches offer convenience
and reduced costs, but they take four to eight hours before effective analgesia
is achieved and take hours or even days for the drug depot to clear from the
skin after the patch is removed. In addition, passive transdermal patches do not
offer precise baseline dosing from patient to patient and do not address the
need for bolus dosing required to address acute episodes of pain.
 
     Products Under Development. The Company believes an iontophoretic delivery
system for hydromorphone may be a favorable alternative to the administration of
morphine by infusion for acute post operative pain and for chronic pain in the
hospice or home care setting. Hydromorphone is approximately ten times more
potent than morphine and has added therapeutic advantages, including lower
incidence of nausea and vomiting (which frequently accompanies the
administration of morphine), and more effective analgesia with no stupefying and
minimal hypnotic effects. Through the Elan Agreements, the Company obtained
rights to prototype wearable iontophoretic drug delivery systems for the
delivery of hydromorphone and to the preclinical, Phase I and limited Phase II
clinical data generated by Elan in testing the device. The Company believes the
additional clinical trials necessary to market this product may be of relatively
short duration in comparison to an NCE, since hydromorphone's safety and
efficacy profile is well known and the clinical
 
                                       41
<PAGE>   43
 
endpoints are both well established and easy to measure. See "Risk
Factors -- Uncertainty of Government Regulation."
 
     In addition to a system for the delivery of hydromorphone, the Company
believes a market exists for an iontophoretic drug delivery system for fentanyl,
a narcotic analgesic more potent than hydromorphone, which has been used
primarily during surgery. The Company conducted a preliminary blood level study
using fentanyl and, using data from that study, designed advanced electrodes
which a former collaborative partner used in a subsequent fentanyl human blood
level test. These studies demonstrated that fentanyl can be delivered by
iontophoresis to achieve the delivery rates and blood levels necessary for pain
control.
 
     Due to its short half-life in the body, injectable fentanyl is not
generally used for the treatment of moderate to severe post-operative or chronic
pain. However, the increased use of home infusion therapy and the development of
a passive transdermal patch have demonstrated that fentanyl can be delivered at
therapeutic levels, making the drug suitable for new indications not previously
possible with injections. The Duragesic transdermal fentanyl patch, which was
developed by Alza and is marketed by Janssen Pharmaceuticals, was introduced in
1992 and had annual worldwide sales of $205 million in 1996.
 
     As a result of an existing contractual obligation with its former
collaborative partner, the Company has agreed not to pursue development of a
fentanyl pain product until the second quarter of calendar year 1998. Further,
the Company's ability to market a product using fentanyl in the United States
may be limited by certain litigation before the PTO. See "Risk
Factors -- Dependence on Patents and Proprietary Technology" and
"Business -- Collaborative Relationships and Licenses."
 
  OSTEOPOROSIS
 
     Osteoporosis is a progressive disease that affects more than 25 million
people in the United States, most commonly post-menopausal women. The financial
costs associated with osteoporosis exceed $10 billion each year. Novartis and
the Company believe the overall therapeutic profile of the osteoporosis drug
currently under development may be optimized or enhanced through the use of an
iontophoretic drug delivery system. As a result, they have entered into an
agreement for the development by the Company of an iontophoretic drug delivery
system using the drug for the treatment of osteoporosis. The drug is currently
scheduled to enter Phase I clinical trials in 1998. See
"Business -- Collaborative Relationships and Licenses."
 
  OTHER POTENTIAL PRODUCT APPLICATIONS
 
     The Company has an active program of identifying and developing
iontophoretic drug delivery products for various therapeutic indications where
the Company believes there is a potential market need, where a suitable
water-soluble ionic drug is available and where that drug can be delivered
through iontophoresis in therapeutic quantities on a cost-competitive basis. The
Company has identified certain drugs and therapeutic indications as potential
product opportunities, and has undertaken preliminary steps toward verifying the
market need and technical feasibility of iontophoretic delivery of those drugs.
In addition, through the Elan Agreements, the Company acquired certain
in-process research and development, including exclusive world-wide rights for
the commercial exploitation of certain iontophoretic patents, know-how and
clinical data. The Elan technology includes in vitro feasibility studies
conducted on 64 drugs (including several peptide drugs), in vivo blood level
animal studies on 18 of those drugs and human blood level studies on nine of
those drugs. See "Business -- Products and Products Under
Development -- Osteoporosis."
 
     As part of its continuing product development program, the Company will
evaluate the feasibility of iontophoretic delivery of biotechnology derived
peptides, small proteins and oligonucleotides for applications where existing
drug delivery systems have significant limitations. The Company also intends to
examine the use of its iontophoretic system to deliver anti-emetics to treat
postsurgical nausea and vomiting induced by or secondary to chemotherapy,
surgery, migraine headache or AIDS.

COLLABORATIVE RELATIONSHIPS AND LICENSES
 
     A principal component of the Company's commercial strategy is to develop
products, where appropriate, in collaboration with established pharmaceutical
companies or other strategic partners. These collaborative partners may provide
proprietary drugs, technology, financial resources, research and pharmaceutical
manufacturing capabilities or marketing infrastructure to aid in the development
and commercialization of the Company's products and potential future products.
Depending on the availability of financial, marketing and scientific resources
and other factors, the Company may also license or cross license its technology
or products to others and retain profit sharing, royalty, manufacturing,
co-marketing, co-promotion or similar rights. Any such arrangements could limit
the Company's flexibility in pursuing alternatives for the development or
commercialization of its products.
 
     The Company has entered into the following collaborative relationships and
license arrangements:
 
     Novartis Agreement. In July 1995 as amended in March 1996, the Company
entered into various research and development agreements (the "R&D Agreements")
with the ethical pharmaceuticals division of Ciba-Geigy Corporation ("Ciba") to
evaluate the feasibility of delivering a number of Ciba compounds for several
therapeutic applications utilizing the Company's iontophoretic drug delivery
technologies, including certain of its existing iontophoretic devices. In
connection with the R&D Agreements, the Company formed Dermion to conduct the
Company's iontophoretic drug delivery research and development activities other
than those relating to the Company's current products, and Ciba then acquired a
20% equity interest in Dermion. In 1997, Ciba was merged with Sandoz Corporation
to form Novartis Pharma A.G.
 
     Under the 1997 Amendments, effective November 1, 1997, Novartis exchanged
its 20% equity interest in Dermion for 238,541 Common Shares and warrants to
acquire an additional 18,750 Common Shares at an exercise price of $21.60 per
share. Novartis may currently exercise one-third of the warrants, and will
obtain the right to exercise an additional one-third of the warrants in each
instance, when it agrees to provide research and development funding at a
minimum level of $1.5 million per year under the R&D Agreements for each of the
calendar years 1999 and 2000. The warrants, once exercisable, may be exercised
at any time through November 1, 2002.
 
     In connection with the R&D Agreements, the Company and Dermion granted
Novartis perpetual non-exclusive, royalty bearing licenses to the Company's
iontophoretic technology. Further, other than in collaboration with Novartis,
the Company has agreed that, during the term of the agreement (and, under
certain circumstances, for a period of up to two years thereafter), the Company
will not develop any product in certain Novartis fields, as defined in the
agreement, without Novartis' consent.
 
     Pursuant to the R&D Agreements, as amended, Novartis will provide Dermion
with research funding through December 31, 1998 for the continued development of
proprietary iontophoretic drug delivery systems to deliver Novartis compounds
and has the option to renew the research and funding for successive one year
periods. Presently, Dermion is devoting the majority of its research and
development efforts to the development of these systems and products for
Novartis compounds. One of the compounds covered by the R&D Agreements is
scheduled to enter Phase I clinical trials during 1998. The R&D Agreements may
be terminated by Novartis or the Company at any time on at least six months'
notice.
 
     The R&D Agreements, as amended, require Novartis to pay Dermion milestone
payments in connection with products developed for Novartis by Dermion, based on
the successful completion of certain later stage development objectives.
Additionally, Novartis is required to pay Dermion royalties on sales by Novartis
of products and systems developed by Dermion. No such sales have yet occurred
and no royalties have been received by Dermion.
 
     The Company has also agreed that, during the term of the agreement with
Novartis and for a period of five years thereafter, the Company will negotiate
in good faith to license to Novartis rights to any iontophoretic drug delivery
technologies developed or acquired by the Company but which are not covered
under the existing license agreements (the "Second Generation Technology").
Further, the Company has agreed to negotiate such additional licenses prior to
entering into any agreement to license or otherwise transfer any rights to such
Second Generation Technology to a third party. Under the 1997 Amendments, the
parties
 
                                       43
<PAGE>   45
 
agreed to treat the Elan technology acquired by the Company as Second Generation
Technology. Accordingly, the Company intends to negotiate with Novartis to
license such technology to Novartis prior to initiating efforts to negotiate any
rights to such technology with any third party. Under the R&D Agreements, as
amended, the parties agreed that they will jointly own the technology developed
in the collaboration.
 
     The Company's agreements with Novartis contain contractual restrictions on
any change of control of Dermion (either through the sale of IOMED's stock in
Dermion or through the sale by Dermion of its securities, assets or business).
Through March 1998, any such change of control is prohibited and, during the
remaining term of the R&D Agreements, and for one year thereafter, Novartis has
a right of first offer to purchase Iomed's interest in Dermion or the assets of
Dermion in the event of any proposed change of control of Dermion. The right of
first offer does not extend to any overall change of control transaction
involving IOMED, such as the sale by IOMED of its securities or assets, or a
merger or consolidation. See "Risk Factors -- Reliance on Collaborative
Partners."
 
     Elan Agreements. Effective March 1997, the Company entered into the Elan
Agreements. Under the Elan Agreements, the Company acquired exclusive, worldwide
licenses to certain of Elan's iontophoretic drug delivery technologies,
including know-how and over 250 issued and 47 pending United States and foreign
patents. In exchange for those rights, the Company paid Elan $15.0 million
through the issuance to Elan of the Elan Notes, issued Elan warrants to
purchase, through December 1, 2003, 104,166 Common Shares of the Company at a
price of $21.60 per share, and agreed to pay Elan a royalty on net revenues
derived by the Company from the licensing or sale of its products. See
"Transactions Related to the Offering" and "Certain Transactions."
 
     Alza Agreement. Alza has developed competitive iontophoretic drug delivery
technology and is, by its published reports, undertaking to develop products
that may be competitive with the Company's products. As a result of the
uncertainty of the Company's and Alza's respective patent rights for certain
iontophoretic delivery technologies, in 1993, the Company entered into a
cross-license agreement with Alza. Under the agreement, the companies, among
other things, exchanged non-exclusive, royalty free rights to certain patented
technologies which each party believed to be of significant strategic importance
to the potential technological success of many iontophoretic drug delivery
applications. One patent sublicensed by Alza to the Company under the agreement
bears a nominal royalty rate if used. Both parties are prohibited from assigning
their rights under the agreement to certain named companies or any other entity
that derives more than 50 percent of its income from the development, licensing
and/or sale of drug delivery systems to other pharmaceutical companies without
first receiving the consent of the other party. Restrictions imposed on the
Company's ability to assign its rights under this agreement may have the effect
of prohibiting a sale of the Company to such named companies, or may otherwise
limit the Company's ability to capitalize on the commercial and other economic
potential of these technologies. The Company does not believe these restrictions
inhibit its existing business development strategy. See "Risk
Factors -- Anti-Takeover Provisions of the Company's Articles of Incorporation;
Utah Law and Certain of the Company's Agreements."
 
     University of Utah Agreement. In 1974, the Company entered into a licensing
agreement with the University of Utah Research Foundation (the "University").
Under the agreement, which was amended in 1993, the Company obtained an
exclusive license to certain iontophoretic drug delivery and prosthetic
technologies developed at the University. Under the terms of the amended
license, the Company is obligated to pay the University a royalty on all sales
of its iontophoretic drug delivery products through the year 2007. In December
1996, the Company sold the assets comprising its prosthetic technologies
operations to Fillauer, Inc. and, in connection with that sale, sublicensed its
rights in the prosthetic technologies covered by the license to Fillauer, Inc.
 
     Fillauer Agreements. Prior to January 1997, the Company provided
state-of-the-art prosthetics products to amputees throughout the United States,
Canada and Western Europe through its Motion Control division. Motion Control's
principal products were the Utah Artificial Arm and the ProControl II advanced
myolectric prostheses for above and below the elbow amputees.
 
     In December 1995, the Company sold the assets of its prosthetics
technologies operations to Fillauer, Inc. for $1.0 million and granted Fillauer
an exclusive, worldwide license and sublicense to the patents, trademarks,
 
                                       44
<PAGE>   46
 
know-how and other intellectual property of the Company relating to its
prosthetics products. Under the terms of the sublicense agreement, the Company
will receive license fees and royalties on future sales of such products.
 
     Laboratoires Fournier Agreement. In July 1993, the Company entered into an
agreement with Laboratoires Fournier, a private French pharmaceutical company,
for the joint research and development of wearable integrated iontophoretic
systems, with primary effort devoted to the development of systems for the
treatment of acute post operative pain and patient controlled analgesia. The
companies subsequently concluded that certain United States patents issued to
Alza for the iontophoretic delivery of fentanyl and its analogs after the
Company and Laboratoires Fournier had entered into their agreement posed a
potential barrier to the commercial viability of the proposed system in the
United States. As a result, the Company elected to suspend development efforts
in the area. In February 1996, the parties terminated their collaborative
research and development activities and amended their initial agreement. In
connection with the termination of their collaborative efforts the Company
issued Laboratoires Fournier 337,837 Common Shares in satisfaction of a $3.0
million loan Laboratoires Fournier had made to the Company. Under the amended
agreements, both companies have rights to all jointly developed iontophoretic
technologies and know-how, and Laboratoires Fournier has a limited non-exclusive
license to the Company's previously existing proprietary iontophoretic
technologies. The Company also agreed not to pursue development of delivery
systems for systemic pain control, including conscious sedation and pain
management, for a two year period ending February 1998.
 
   
     Boston University Agreement. In December 1997, the Company acquired a
non-exclusive, fully-paid, perpetual, non-royalty bearing license to certain
iontophoretic drug delivery technology developed by Boston University. The
agreement also provides the Company with the right to sublicense the technology
upon the payment of a sublicense fee.
    
 
MANUFACTURING
 
     The Company manufactures, tests, inspects, packages and ships its products
from an approximately 18,000 square foot leased manufacturing facility located
in Salt Lake City, Utah. The Company's manufacturing activities primarily relate
to its manufacture of electrode kits. The Company does not manufacture or
repackage any drugs or compounds used in its delivery systems and outsources the
manufacture and assembly of its Phoresor dose controllers.
 
     The Company and certain of its suppliers are required to comply with FDA
regulations governing manufacturing practices, including the Quality System
Regulation, which mandate controls for product design, control and quality. The
Company believes it is in compliance with the Quality System Regulation. The
Company recently received its ISO 9001 and CE Mark certifications, which are
standards imposed by certain European countries on drug and medical devices
manufacturers. The Company has good manufacturing practices audits conducted on
a regular basis.
 
     Manufacture of Electrodes. The Company's iontophoretic drug delivery
electrode kits are manufactured and assembled using several proprietary
materials, processes and production technologies developed by the Company in
conjunction with its equipment and material suppliers. The Company assembles its
electrodes from internally manufactured components and outsourced components
that are manufactured by third parties to the Company's specifications. Each of
the Company's existing electrode kits is assembled on a separate production
line. The key components of the Company's electrodes are the rehydratable drug
containment pads (which use either the Company's multi-laminate hydrogel or its
gel sponge technologies), and silver and silver/silver chloride conductive
elements.
 
     The Company manufactures the rehydratable drug containment pads used in its
electrodes. These pads are manufactured, using the Company's proprietary
processes, from multiple layers of a polymer material or from a sponge material
impregnated with a hydrogel. The silver and silver/silver chloride conductive
elements used in the Company's electrodes are manufactured for the Company to
its specifications by a third party. The Company has manufactured internally all
of the electrodes it has sold, and believes its electrode manufacturing capacity
can be expanded to meet its needs for the foreseeable future.
 
                                       45
<PAGE>   47
 
     The Company has adopted a "team" approach on its electrode assembly lines
and, by changing the production flow process and automating certain production
steps, was able to reduce manufacturing personnel from 70 in 1992 to 26 persons
in 1997, thereby reducing per unit production costs while increasing product
lines and production levels. The Company intends to use a portion of the
proceeds of the Offering for capital equipment to further automate the assembly
and packaging of the Company's electrodes, to increase capacity and to reduce
costs. See "Use of Proceeds."
 
     Manufacture of Dose Controllers. The Company's patented Phoresor
iontophoretic dose controllers employ a variety of sub-assemblies and components
that are designed or specified by the Company, including certain
microprocessors, circuit boards, on-board software, electrical lead wires and
control panels. These components and subassemblies are typically manufactured
for the Company by third parties, which then ship them to a contract
manufacturer for final assembly, testing and inspection in accordance with the
Company's specifications. The Company's manufacturing activities for the
Phoresor dose controllers are limited to design, labeling, inspection and
packaging.
 
     The Company's second and third generation dose controllers are in various
stages of design, research, and development and may require additional clearance
or PMA approval from the FDA prior to marketing. The Company, alone or in
conjunction with its development partners, will design the products and, in
combination with its suppliers, will manufacture and assemble prototypes and
clinical quantities. Upon completion of the design, specifications and testing,
the Company intends to subcontract the manufacture and assembly of all
commercial quantities of its dose controllers to electronics companies that
specialize in such work. See "Risk Factors -- Uncertainty of Government
Regulation."
 
     The Company purchases certain components and materials used in its products
from single source suppliers pursuant to existing purchase orders and
agreements. See "Risk Factors -- Dependence on Single Sources of Supply."
 
SALES AND DISTRIBUTION
 
     The Company's marketing strategy is to position its proprietary
iontophoretic drug delivery products in the marketplace as the preferred means
of drug delivery for a wide range of drugs. The strategy employs the use of
multiple sales and distribution channels, including (i) a network of medical
supply dealers; (ii) a direct sales force; and (iii) collaborative marketing
partners. The Company intends to use these distribution channels, both singly
and, for certain products, in combination, to maximize the Company's marketing
resources.
 
     Local Inflammation Products. The Company has historically targeted its
sales efforts for its drug delivery system for acute local inflammatory
conditions to the rehabilitative medicine, physical therapy and related
specialty markets. The Company employs a nationwide distribution network
consisting of approximately 50 durable medical equipment and physician supply
dealers to sell and distribute its products in those markets. This dealer
network is supported by the Company's six regional sales managers and four
internal customer service representatives. In addition to the Company's sales
and distribution efforts for its local inflammation products in the United
States, it maintains marketing and sales activities in international markets,
including Europe, Scandinavia, Australia, South Korea, Singapore and Hong Kong.
These sales are made primarily through independent distributors operating in
those countries.
 
     The Company intends to expand its marketing efforts by expanding and
improving its existing product lines and expanding its sales and distribution
capabilities into new segments of the inflammation market (including the
podiatry, chiropractic and primary care physician markets) through the use of
additional specialty dealers. In order to enhance its marketing efforts, the
Company is pursuing an NDA for its acute local inflammation drug delivery system
for Dexamethasone. The Company believes an NDA, if approved, will allow it to
actively promote this product and will enhance the Company's ability to
establish the Dexamethasone product as a primary treatment option for acute
local inflammation conditions.
 
     Local Dermal Anesthetic Products. In 1997, the Company launched an
iontophoretic drug delivery system for Iontocaine. The Company has initially
targeted its sales efforts for the product in the pediatric
 
                                       46
<PAGE>   48
 
hospital market under the name Numby Stuff. In order to access this market, the
Company intends to hire a direct sales staff of approximately 40 persons over
the next four years to market Numby Stuff. To date, the Company has hired and
trained seven sales agents, and intends to hire and train the remaining 33 sales
representatives by the end of 1999. There can be no assurance the Company will
be able to recruit and hire such personnel successfully within such time frame,
or at all. The Company also intends to expand its marketing efforts for its
Iontocaine products for other applications and to the general physician office
and international markets through the use of collaborative marketing partners.
In addition, under the terms of the Company's agreements with ACH, ACH has
agreed to assist the Company in introducing Numby Stuff to pharmacy directors
and other clinical specialties within ACH member hospitals. ACH has also agreed
to provide the Company with other marketing and sales assistance, including
access to certain marketing data developed by ACH.
 
     Products Under Development. The Company is developing a number of
iontophoretic drug delivery systems for other therapeutic indications, including
remission of pre-term labor, conscious sedation, post operative and chronic pain
control and osteoporosis. If any of these products is successfully developed and
approved by the FDA, the Company would market those products in the hospital
market through its direct sales force and to the physician office, international
and other specialty markets through one or more collaborative marketing
partnerships.
 
PATENTS AND PROPRIETARY RIGHTS
 
     The Company's iontophoretic drug delivery technologies include patents,
trademarks, trade secrets and other proprietary know-how. These technologies are
used in various combinations in the testing, evaluation and formulation of
optimal ionic drug solutions and in the research, development, design and
manufacture of microprocessor controlled power supplies and iontophoretic
electrodes which are specifically designed and constructed for particular
therapeutic applications.
 
     The Company has implemented a policy of actively patenting and maintaining
as trade secrets and proprietary information all inventions and technologies
which it believes are important to its business operations. The Company
generally seeks patent protection for its key proprietary technologies and
technological products in the United States, Canada, Europe and Japan. The
Company also relies on a number of trade secrets, know-how, continuing
technological innovations and licensing opportunities to develop and maintain
its competitive position. The Company's patent committee meets regularly to
review and make recommendations to the Company's management regarding patent and
invention issues.
 
     As of October 1, 1997, the Company held or had rights to utilize 60 United
States patents and 245 foreign patents relating to its iontophoretic drug
delivery technology, and has (or has the rights to utilize) 15 pending patent
applications in the United States and 47 pending patent applications in foreign
countries for that technology. The Company also owns or has licensed rights to
three issued and one pending United States patent governing the design and
manufacture of certain myoelectric prosthetic devices, including the Utah
Artificial Arm, which it has sublicensed to a third party in connection with the
sale of the Company's Motion Control division in December 1996. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
     The medical products industry has recently seen extensive litigation
regarding patents and other intellectual property rights. Intellectual property
litigation is expensive and time consuming and, if decided adversely to a party,
can result in substantial loss or diversion of revenues for, and could have a
material adverse effect on the business operations of, the losing litigant.
There can be no assurance the pending patent applications filed by the Company
will be approved by appropriate governmental agencies, or that the Company's
issued or pending patents will not be challenged or circumvented by its
competitors. There can also be no assurance the Company will not become a party
to intellectual property right litigation and its concomitant adverse effects.
Further, there can be no assurance infringement claims will not be asserted by
other parties in the future against the Company, or that, in such event, the
Company would prevail or be able to obtain licenses on reasonable terms if it
did not prevail in those infringement claims. Adverse determinations in any
litigation could subject the Company to significant liabilities and/or require
the Company to
 
                                       47
<PAGE>   49
 
obtain licenses from third parties. If the Company is unable to obtain necessary
licenses or is unable to develop or implement alternative technology, it could
be unable to manufacture and sell the affected products. Any of these outcomes
could have a material adverse effect on the Company's business financial
condition and results of operations.
 
     In August of 1993, the PTO issued a patent to Alza relating to the
iontophoretic delivery of fentanyl. Alza's subsequent patent request in Europe
has been denied, and its United States patent was reexamined by the PTO. In the
reexamination, all of the substantive claims that Alza made in the original
patent relating to fentanyl and its analogs were denied. Alza has appealed the
PTO's decision and, as a result, there can be no assurance Alza will not regain
its patent position. If Alza is successful in its appeal of the PTO's decision,
and if the Company proceeds in the development of an iontophoretic fentanyl
product, the Company may be required to obtain a license from Alza Corporation
to market an iontophoretic drug delivery system for fentanyl in the United
States. There can be no assurance the Company would be able to obtain a license
on terms which are acceptable to the Company, if at all. See "Risk
Factors -- Dependence on Patents and Proprietary Technology."
 
     In addition to its patented technology, the Company relies on trade
secrets, technical know-how and continuing invention to maintain its competitive
position and products. The Company works actively to foster continuing
technological innovation by its employees and consultants in order to maintain
its competitive position, and has taken security measures to protect its trade
secrets and periodically explores ways to further enhance its trade secret
security. The Company requires each of its employees and consultants to execute
an intellectual property and invention agreement. The agreement generally
provides that all inventions, designs, formulas, works of authorship,
compositions of matter and discoveries made, conceived of or developed by the
individual and all confidential information disclosed or made know to the
individual during the term of his or her relationship with the Company will be
assigned to and remain the exclusive property of the Company and that it will be
maintained as confidential and not disclosed to third parties at any time except
under specified circumstances. The agreements also prohibit the employee or
consultant from directly or indirectly competing with the Company during the
term of their relationship with the Company and from recruiting the Company's
employees on behalf of competitors after the termination of that relationship.
There can be no assurance these measures will provide adequate protection for
the Company's trade secrets or other proprietary information. There can also be
no assurance the Company's competitors will not independently develop
substantially equivalent proprietary information and techniques or otherwise
gain access to the Company's trade secrets.
 
     The Company engages in a number of collaborative relationships with third
parties. Under the terms of these relationships, the Company has agreed to act
as the licensor or licensee of certain technology and to engage in a number of
research and development activities relating to that technology or to the
development of iontophoretic drug delivery systems. Under these arrangements,
Alza and Laboratoires Fournier have obtained licenses to certain of the
Company's proprietary iontophoretic technologies. These companies will compete
with the Company for contracts with collaborative partners and are independently
developing iontophoretic drug delivery systems that will compete directly with
many of the products currently being developed by the Company. See "Risk
Factors -- Reliance on Collaborative Partners," "Business -- Collaborative
Relationships and Licenses" and "Business -- Competition."
 
GOVERNMENT REGULATION
 
     The research, development, manufacture, and marketing of both drugs and
medical devices, including the Company's iontophoretic drug delivery systems,
are subject to extensive regulation by the FDA in the United States and by
comparable authorities in other foreign countries. These national agencies and
other federal, state and local entities regulate, among other things, research
and development activities and the testing, manufacture, safety, effectiveness,
labeling, storage, record keeping, approval, advertising, promotion and
reporting requirements related to product injury of the Company's products. The
regulations applicable to the Company's products may change as the presently
limited number of approved iontophoretic drug delivery products increases and
regulators acquire additional experience in this area. The FDA has broad
authority to enforce the medical devices and drug regulations and laws, and
noncompliance can result in a variety of
 
                                       48
<PAGE>   50
 
regulatory responses ranging from warning letters and mandatory product recalls
to civil or criminal actions and penalties. See "Risk Factors -- Uncertainty of
Government Regulations."
 
     The Company's iontophoretic drug delivery products involve a medical device
component, thereby subjecting such products to compliance with the FDA's
regulations governing medical devices. Where such medical devices are labeled
for use with a specific pharmaceutical product for a specific therapeutic
indication, they are subject to the FDA's regulations governing both medical
devices and pharmaceutical products. The Company believes that most, if not all,
of its future iontophoretic drug delivery systems will involve a pharmaceutical
component or specific labeling for use with a pharmaceutical product.
 
     Products regulated as medical devices may not be commercially distributed
in the United States unless they have been cleared or approved by the FDA, or
unless they are otherwise exempted from the FDA's regulations. Currently, there
are two methods for obtaining FDA clearance or approval of medical devices.
Devices deemed to pose less risk are placed in class I (general controls) or
class II (general and special controls) and qualify for 510(k) notification, a
procedure under sec. 510(k) of the Federal Food, Drug, and Cosmetic Act (the
"FDC Act"). In order for a device to qualify under the sec. 510(k) notification
procedure, the manufacturer must, among other things, establish that the product
to be marketed is substantially equivalent in intended use and safety and
effectiveness to another legally marketed class I or class II device or to a
"preamendment" class III device (as defined below) for which FDA has not called
for PMAs. In such cases, marketing of the product may commence when the FDA
issues a letter finding that there is a substantial equivalence to the legally
marketed device. The FDA may require, in connection with a 510(k) notification,
the manufacturer to provide the FDA with test results from animal studies and/or
human clinical trials. The Company believes that it typically takes between four
and 12 months to obtain a 510(k) clearance, but it can take longer.
 
     A 510(k) clearance is also required when the manufacturer makes changes or
modifications to a cleared device that could significantly affect safety or
effectiveness, or where there is a major change or modification in the intended
use of a cleared device. In such cases, the manufacturer is the party which
initially determines if the change or modification is of a kind or nature that
would necessitate a new 510(k) notification. The FDA's regulations provide only
limited guidance in making such determinations. The FDA has cleared the
Company's electrical dose controller and electrode kits for marketing under a
510(k) clearance. Since obtaining its 510(k) clearances, the Company has made
modifications to its products. Based on the checklist developed by the FDA to
assist manufacturers in determining whether they are required to obtain a 510(k)
clearance for a modified device, the Company has determined that a new 510(k)
submission was not required in connection with the commercial introduction of
such products. However, there can be no assurance that the FDA will not require
the Company to obtain additional 510(k) clearances with respect to those
products. If the FDA requires the Company to submit a new 510(k) notice for any
device modification, the Company may be prohibited from marketing the modified
device until the 510(k) notice is cleared by the FDA.
 
     A medical device that does not qualify for the 510(k) clearance is placed
in class III, which is reserved for devices deemed by the FDA to pose the
greatest risk (e.g., life-sustaining, life supporting or implantable devices, or
devices that are not substantially equivalent to a legally marketed class I or
II device). The manufacturer of such a device must file a PMA application under
sec. 515 of the Drug Act. A PMA application generally requires a much more
complex submission than a 510(k) notification and typically requires a showing
that the device is safe and effective based on extensive and costly preclinical
and clinical testing, as well as information about the device and its components
regarding, among other things, manufacturing, labeling and promotion. Upon
submission, the FDA determines if the PMA application is sufficiently complete
to permit substantive review and, if so, the application is accepted for filing.
The FDA then commences an in-depth review of the PMA application, which the
Company believes can last from one to three years, or even longer. Even after
approval of a PMA, a new PMA or PMA supplement is required in the event of a
modification to the device, its labeling or its manufacturing process.
 
     A preamendment class III device is one that was on the market before May
28, 1976. A device that is substantially equivalent to a preamendment class III
device can be brought to market through the 510(k) process until the FDA either
calls for the submission of PMA applications or downclassifies the device to
 
                                       49
<PAGE>   51
 
class I or II. Manufacturers of preamendment class III devices that the FDA
retains in class III must submit PMA applications 90 days after the publication
of a final regulation calling for PMAs. In such event, a PMA must be submitted
even if the device has already received 510(k) premarket clearance. On the other
hand, if the FDA downclassifies a preamendment class III device to class I or
II, a PMA application is not required and such devices may continue to be
marketed through the 510(k) process.
 
     An even more lengthy and complex regulatory framework applies to the
labeling and marketing of specific drugs for use with an iontophoresis device.
The activities required before a pharmaceutical product may be marketed in the
United States primarily begin with preclinical testing. Preclinical tests
include extensive laboratory evaluation of product chemistry and other end
points and animal studies to assess the potential safety and efficacy of the
product as formulated. Almost all preclinical studies pertinent to drug approval
are regulated by the FDA under a series of regulations called the Good
Laboratory Practice (GLP) regulations. Violations of these regulations can, in
some cases, lead to invalidation of the studies, requiring such studies to be
replicated.
 
     If the drug is subject to full NDA requirements, FDA approval process
entails (i) conducting preclinical laboratory and animal testing to enable FDA
authorization of an IND application, (ii) initial IND clinical studies to define
safety and dose parameters, (iii) well controlled IND clinical trials to
demonstrate product safety and efficacy, and (iv) submission to the FDA of an
NDA. Preclinical studies involve laboratory evaluation of product
characteristics and animal studies to assess the efficacy and safety of the
drug. Human clinical trials are typically conducted in three sequential phases.
Phase I trials normally consist of testing the product in a small number of
healthy volunteers for safety and pharmacokinetic parameters using single and
multiple dosing regimens. In Phase II trials, the manufacturer evaluates safety,
initial efficacy, and dose ranging of the product for specific indications in a
somewhat larger patient population. Phase III trials typically involve expanded
testing for safety and clinical efficacy in a broad patient population at
multiple clinical testing centers. The manufacturer must also submit a clinical
plan, or "protocol," accompanied by the approval of the institution
participating in the trials, to the FDA prior to commencing each clinical trial
and must obtain the informed consent of subjects in the clinical trial. The FDA
may order the temporary or permanent discontinuation of clinical trials at any
time. All the results of the preclinical and clinical studies on a product are
then submitted to the FDA in the form of an NDA for review. In responding to an
NDA, the FDA may grant marketing approval, require additional testing and/or
information, or deny the application altogether. The process of obtaining FDA
approval for a new product through the IND/NDA process may take several years
and typically involves the expenditure of substantial resources.
 
   
     The Company may be subject to certain user fees that the FDA is authorized
to collect under the Food and Drug Modernization Act of 1997, which reauthorized
the user fees established in the Prescription Drug User Fees Act of 1992 for
certain drugs.
    
 
     Because of the known safety and efficacy profile of Dexamethasone and other
approved drugs for which the Company may seek NDA approval for iontophoretic
delivery, the clinical trials and other studies may not be as lengthy or
extensive as would be required for unapproved new drugs that are subject to full
NDA requirements. This strategy, however, depends upon the Company's ability to
obtain a contractual right to reference in the Company's NDA application of the
safety and efficacy data for such drugs in approved NDAs held by other
companies. The Company has obtained a right to reference safety and efficacy
data for Dexamethasone. There can be no assurance that the Company will be able
to obtain a right of reference for all unapproved drugs that may be used for
iontophoretic delivery. The Company's failure to obtain a right of reference to
safety and efficacy data for any drug for which the Company would like to obtain
approval for iontophoretic delivery could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     The regulatory status of iontophoresis devices is also complex. The FDA has
classified them as class II devices eligible for marketing through 510(k)
premarket clearance when intended for use with a drug whose labeling bears
adequate directions for the device's use with that drug. However, if an
iontophoresis device is intended for use with a drug that is not labeled for use
with the device, the FDA considers the iontophoresis
 
                                       50
<PAGE>   52
 
device to be a preamendment class III device. This status means that the device
at present can be marketed through a 510(k) clearance, but it remains subject to
a call for PMAs.
 
     In an April 1994 document setting forth the FDA's strategy for addressing
preamendment class III devices, the FDA indicated that preamendment class III
iontophoresis devices were among fifteen "high priority" devices that presented
an unreasonably high risk to public health because significant issues of safety
and/or effectiveness were not being resolved or, to the agency's knowledge, had
little probability of being resolved. The FDA indicated that these devices were
not considered candidates for downclassification and were very likely to be
required to be subject to PMAs. This process would involve two steps. First, the
FDA would publish a proposed regulation to require PMAs for iontophoresis
devices having preamendment class III status. After a comment period, FDA would
then publish a final regulation imposing the requirement. The FDA's strategy
document stated the agency's intent to publish a proposed regulation requiring
PMAs for preamendment class III iontophoresis devices in 1996. The agency, to
date, has not published such a regulation.
 
     The Company's Phoresor received 510(k) clearance in 1990 as a preamendment
class III device labeled for use with ions of soluble salts or other drugs. In
1995, the FDA approved an NDA for Iontocaine to be used as a local anesthetic
and delivered iontophoretically by the Phoresor, which effectively moved the
Phoresor into class II for this intended use. Unlike Iontocaine, Dexamethasone
does not have an NDA approval allowing it to be labeled for iontophoretic
delivery. Thus, the Company's Phoresor is a preamendment class III device when
used with Dexamethasone (or any drug other than Iontocaine). No assurance can be
given that the Company will ever obtain an approved NDA for the iontophoretic
delivery of Dexamethasone. The Company's failure to obtain FDA approval of an
NDA for Dexamethasone could have a material adverse effect on the Company's
business financial condition and results of operations.
 
     If the FDA calls for PMAs for preamendment class III iontophoresis devices,
the Company would be required to have a PMA accepted for filing by the FDA
within 90 days after the date of the final regulation calling for PMAs. There
can be no assurance that the Company would be able to complete necessary
clinical studies and otherwise prepare and file a PMA within the prescribed time
period, or that any data and information submitted in a PMA would be adequate to
support approval. The Company's failure to submit a PMA and have it accepted for
filing by the FDA within the required timeframe could result in the Company
being required to cease commercial distribution of the Phoresor for use with
Dexamethasone. Upon timely filing of a PMA, the Company believes (based on FDA's
announced position as to certain other preamendment class III medical devices)
that the FDA would permit continued commercial distribution of the Phoresor for
use with Dexamethasone during the time necessary to review the PMA. There can be
no assurance, however, that the FDA would permit such continued commercial
distribution pending review of a PMA for the device, nor can any assurance be
given that the FDA would approve a PMA filed by the Company. The FDA also could
condition PMA approval upon approval of an NDA permitting Dexamethasone to be
labeled for use with the Phoresor. If the Company were required for any length
of time to cease commercial distribution of the Phoresis System for use with
Dexamethasone, the Company's business, financial condition and results of
operations would be materially and adversely affected pending approval of a PMA
or NDA.
 
     The FDA also regulates the Company's quality control and manufacturing
procedures by requiring the Company and its contract manufacturers to
demonstrate current GMP compliance, including compliance with the Quality System
Regulation (for devices) and the current GMP regulations (for drugs). The FDA's
GMPs require, among other things, that (i) the manufacturing process be
regulated and controlled by the use of written procedures, and (ii) the ability
to produce products which meet the manufacturer's specifications be validated by
extensive and detailed testing at various steps of the manufacturing process.
These regulations also require investigation of any deficiencies in the
manufacturing process, the products produced, or record keeping. The FDA
monitors compliance with these requirements by requiring manufacturers to
register their manufacturing facilities with the FDA and by conducting periodic
FDA inspections of those facilities. If an FDA inspector observes conditions
that might be in violation of GMP requirements, the manufacturer is generally
required to correct those conditions or explain them satisfactorily. If a
manufacturer fails to adhere to GMP requirements, the devices manufactured by
the manufacturer could be considered to be manufac-
 
                                       51
<PAGE>   53
 
tured in violation of the FDC Act and the manufacturer could be subject to FDA
enforcement action that could include fines, plant closure, or a recall of the
Company's product.
 
     Agencies similar to the FDA regulate medical devices and pharmaceutical
products in most developed foreign countries, whereas some other countries allow
unregulated marketing of such devices and products. The Company will be required
to meet the regulations of any foreign country where it markets its products.
There can be no assurance any of the Company's future products will receive FDA
clearance or similar clearance in foreign countries. It is also possible that
regulations governing the manufacture and sale of the Company's products could
change in the future. The Company cannot predict the impact of any such changes
on its business. See "Risk Factors -- Government Regulation."
 
     Various aspects of the Company's business and operations are also regulated
by a number of other governmental agencies including the Drug Enforcement
Agency, U.S. Department of Agriculture, the Environmental Protection Agency, the
Occupational Safety and Health Administration as well as by other federal, state
and local authorities. In addition, international sales are regulated by
numerous foreign authorities. Unanticipated changes in existing regulatory
requirements, failure of the Company to comply with such requirements or
adoption of new requirements could have a material adverse effect on the
Company. There can be no assurance the Company will not be required to incur
significant costs to comply with such laws and regulations in the future or that
such laws or regulations will not have a material adverse effect upon the
Company's business, financial condition and results of operations.
 
COMPETITION
 
     The drug delivery, pharmaceutical and biotechnology industries are highly
competitive and rapidly evolving, with significant developments expected to
continue at a rapid pace. The Company's success will depend upon maintaining a
competitive position and developing products and technologies for efficient and
cost effective drug delivery. The Company's products will compete with other
formulations of drugs and with other drug delivery systems, including other
iontophoretic delivery systems. The Company believes its products will compete
on the basis of quality, efficacy, cost, convenience, safety and patient
compliance, but there can be no assurance any of the Company's products will
have advantages significant enough to cause medical professionals to adopt their
use. New drugs or further developments in alternative drug delivery methods may
provide greater therapeutic benefits for a specific drug or indication, or may
offer comparable performance at lower cost than those offered by the Company's
iontophoretic systems.
 
     The Company is aware of many other competitors in the general field of drug
delivery, including competitors developing injectable or implantable drug
delivery systems, oral drug delivery technologies, passive transdermal systems,
oral transmucosal systems and intranasal and inhalation systems. The Company is
also aware of other companies that have developed or are currently developing
iontophoretic and other electrotransport drug delivery systems. There can be no
assurance that developments by these parties or others will not render the
Company's products or technologies uncompetitive or obsolete. Many of the
Company's existing or potential competitors have substantially greater research
and development capabilities, experience, manufacturing, marketing, financial,
and managerial resources than the Company. Accordingly, the Company's
competitors may succeed in developing competing technologies, obtaining FDA
approval or gaining market share for products more rapidly than the Company, any
of which could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     Both Alza and Empi, Inc. ("Empi") are engaged in the development and/or
marketing of iontophoretic devices. Alza is undertaking the development of
iontophoretic drug delivery systems, but does not currently market any
iontophoretic products. Empi is the Company's primary competitor in the
treatment of acute local inflammation in the physical therapy market and, the
Company estimates, controls a majority of the retail iontophoresis market for
that indication.
 
     Currently, no other company markets an iontophoretic system for the
inducement of local anesthesia. The Company's iontophoretic system for
delivering Iontocaine for the inducement of local dermal anesthesia will
therefore primarily compete with traditional methods of delivering local dermal
anesthetics by needle injection or will be used in circumstances where either no
anesthesia is used, due to the pain associated with
 
                                       52
<PAGE>   54
 
the needle injection (including needle injections themselves), or where topical
anesthetic creams are used. The most effective and widely used topical
anesthetic cream, EMLA, is manufactured and sold by Astra Corporation, a large
Swedish pharmaceutical company. There can be no assurance that the Company can
effectively compete with these products or any other drug delivery systems. See
"Risk Factors -- Uncertainty of Market Acceptance and Limited Market
Penetration" and "Risk Factors -- Intense Competition and Rapid Technological
Change."
 
FACILITIES
 
     The Company maintains leased administrative, manufacturing and research
office space at two facilities. The Company's principal executive offices and
manufacturing facility, which consists of approximately 18,000 square feet of
useable space, are located at 3385 West 1820 South in Salt Lake City, Utah. Its
research facility, which consists of approximately 8,000 square feet of useable
space, is located at 1290 West 2320 South in Salt Lake City, Utah. These
facilities are leased to the Company until December 31, 1999 and December 31,
1997, respectively. The Company is currently negotiating an extension of the
lease on its research and development facilities. The Company believes its
existing facilities are adequate and suitable for its present needs and that
additional space will be available as needed.
 
EMPLOYEES
 
     The Company has assembled a team of medical-products managers and
scientists with considerable experience in iontophoresis, encompassing all of
the key disciplines which the Company believes are necessary to further the
development and implementation of the Company's business.
 
     As of September 1, 1997, the Company had 73 full-time employees, 6 of whom
hold doctorate degrees. Six others hold advanced business or technical degrees.
Of the Company's 73 full-time employees on September 1, 1997, 14 were engaged in
research and development, 35 in manufacturing and quality control, and 24 in
marketing and general administration. The Company's future success depends in
significant part upon the continued service of its key technical and senior
management personnel and its continuing ability to attract and retain highly
qualified technical and managerial personnel. None of the Company's employees is
represented by a labor union. The Company has not experienced any work stoppages
and considers its relations with its employees to be good. See "Risk
Factors -- Retention and Attraction of Key Employees."
 
LEGAL PROCEEDINGS
 
     The Company is not involved in, nor is it aware of, any litigation or
impending litigation.

BOARD OF DIRECTORS AND OTHER INFORMATION
 
     The Company's Articles of Incorporation provide for a classified Board of
Directors consisting of three classes, as nearly equal in number as possible.
The directors in each class serve staggered three year terms. The class three
directors (consisting of Messrs. Wardel and Wood) serve until 1998, the class
two directors (consisting of Mr. Sidwell and Dr. Fara) serve until 1999, and the
class one directors (consisting of Messrs. Weersing and Sember and Dr.
Weinshenker) serve until 2000. At each annual meeting of the shareholders of the
Company, the successors to the class of directors whose term expires at such
meeting will be elected to hold office for a term expiring at the annual meeting
of shareholders held in the third year following the year of their election. The
Company's Articles of Incorporation provide that directors may be removed only
for cause and only by the affirmative vote of the holders of two-thirds of the
Common Shares entitled to vote.
 
BOARD OF DIRECTORS' COMMITTEES
 
     The Board of Directors has established four committees, the Executive
Committee, Audit Committee, Compensation Committee and Special Committee. Each
of these committees is responsible to the full Board of Directors, and its
activities are subject to approval of the Board of Directors. The Executive
Committee is charged with overseeing the operations of the Company, and
generally has all of the authority of the full Board of Directors, between
regularly scheduled meetings of the full Board of Directors. The Executive
Committee is comprised of Mr. Weersing, Dr. Weinshenker and Mr. Wardle. The
Audit Committee reviews the scope and results of the annual audit of the
Company's consolidated financial statements conducted by the
 
                                       56
<PAGE>   58
 
Company's independent accountants, the scope of other services provided by the
Company's independent accountants, proposed changes in the Company's financial
and accounting standards and principles, and the Company's policies and
procedures with respect to its internal accounting, auditing and financial
controls. The Audit Committee also examines and considers other matters relating
to the financial affairs and accounting methods of the Company, including the
selection and retention of the Company's independent accountants. The Audit
Committee is comprised of Mr. Weersing, Dr. Fara and Mr. Sidwell. The
Compensation Committee administers the Company's compensation programs, reviews
and recommends to the Board of Directors compensation arrangements for senior
Company management and directors, and performs such other duties as may from
time to time be determined by the Board of Directors. In addition, the
Compensation Committee is responsible for administering the Company's stock
option plans. The Compensation Committee is comprised of Mr. Weersing, Dr. Fara
and Mr. Wardle. There are no interlocking relationships, as described by the
Securities and Exchange Commission, between the Compensation Committee members.
The Special Committee is charged with overseeing the actions to be taken by the
Company with respect to the Offering, and generally has all of the authority of
the full Board of Directors on issues relating to the Offering. The Special
Committee is comprised of Dr. Weinshenker, Mr. Weersing and Mr. Wood. See
"Employee Benefit Plans."
 
DIRECTOR COMPENSATION
 
     Directors are not paid any cash compensation for attendance at directors'
meetings or for attending or participating on any committee. Directors are
reimbursed, however, for any reasonable out-of-pocket expenses they incur in
connection with attendance at meetings. In addition, all non-employee directors
are eligible to participate in the Company's stock option plans. Upon the
approval of the Board of Directors, certain non-employee directors have been
granted non-qualified options to purchase Common Shares. Dr. Fara and Messrs.
Sidwell and Wood have received options to purchase 6,250, 5,208 and 4,166 Common
Shares, respectively. The option grants vest over a four-year period. All such
options are exercisable at an exercise price equal to the fair market value of
the Common Shares on the date of grant (as adjusted for stock splits and similar
transactions), and are subject to certain vesting schedules. The number of
shares subject to any such grants, and the exercise price(s) of the stock
underlying those grants, are determined by the Compensation Committee and
approved by the Board of Directors.

(1) For purposes of determining the values of the options held by the Named
    Executive Officers, the Company has assumed that the Common Shares
    underlying the options had a value of $6.72 per share on June 30, 1997,
    which is the estimated fair market value the Board of Directors attributed
    to the Common Shares in March, 1997, in connection with certain grants of
    options under the Company's stock option plans. The option value is based on
    the difference between the fair market value of the shares on June 30, 1997,
    and the option exercise price per share, multiplied by the number of Common
    Shares subject to the option.
 
LIMITATIONS OF LIABILITY AND INDEMNIFICATION
 
     The Company's Articles of Incorporation limit the personal liability of
directors and officers for monetary damages to the maximum extent permitted by
Utah law. Under Utah law, such limitations include monetary damages for any
action taken or failed to be taken as an officer or director except for (i)
amounts representing a financial benefit to which the person is not entitled,
(ii) liability for intentional infliction of harm on the corporation, or its
shareholders, (iii) unlawful distributions, or (iv) an intentional violation of
criminal law. The Articles of Incorporation also provide that the Company will
indemnify its directors and officers against any damages arising from their
actions as agents of the Company, and that the Company may similarly indemnify
its other employees and agents. The Company is also empowered under its Articles
of Incorporation to enter into indemnification agreements with its directors and
officers.
 
     The Company's Bylaws provide that, to the full extent permitted by the
Company's Articles of Incorporation and the Utah Revised Business Corporation
Act, the Company will indemnify (and advance expenses to) the Company's
officers, directors and employees in connection with any action, suit or
proceeding (civil or criminal) to which those persons are made party by reason
of their being a director, officer or employee.
 
     At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent of the Company where indemnification by the
Company would be required or permitted. The Company is not aware of any
threatened litigation or proceeding which would result in a claim for such
indemnification.

EMPLOYEE BENEFIT PLANS
 
     Stock Option Plans. The Company has adopted and approved two incentive
compensation plans. The Company's 1988 Stock Option Plan (the "Stock Option
Plan") was approved and adopted by the Company's Board of Directors in April
1988 and was approved by its shareholders in November 1988. The Company's 1997
Share Incentive Plan (the "Share Incentive Plan") was approved and adopted by
the Company's Board of Directors in October 1997 and was approved by its
shareholders in November 1997. The Stock Option Plan and Share Incentive Plan
provide for grants to employees, officers, directors and consultants of both
non-qualified stock options and "incentive stock options" (within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code")). The
Share Incentive Plan also provides for the grant of certain other incentive
compensation, including stock awards, stock appreciation rights, dividend
equivalent rights, performance-based awards and cash bonus rights. The purpose
of the Stock Option Plan and Share Incentive Plan is to attract and retain the
best available personnel to the Company and to encourage stock ownership by the
Company's employees, officers, directors and consultants in order to give them a
greater personal stake in the success of the Company.
 
     A total of 520,833 Common Shares were reserved for issuance under the Stock
Option Plan. As of November 1, 1997, options to purchase a total of 135,679
Common Shares had been exercised, options to purchase a total of 339,512 Common
Shares at a weighted average exercise price of $4.80 per share were outstanding,
and 45,642 Common Shares remained available for future option grants or awards.
A total of 312,500 Common Shares were reserved for issuance under the Share
Incentive Plan. The Board of Directors has not granted any options for, or
issued any Common Shares under, the Share Incentive Plan.
 
     The Stock Option Plan is administered by the Compensation Committee, which
determines and designates the recipients of the options, the dates the options
are granted, the number of Common Shares subject to the options, option prices,
vesting terms, fair market value of the Common Shares, duration of the options
and whether any options granted to employees are to be incentive stock options
or non-qualified options.
 
     The exercise price of all options granted under the Stock Option Plan must
be at least 100% of the fair market value of the Common Shares on the grant
date. The term of an option may not exceed ten years from the date of grant.
With respect to any participant who owns shares possessing more than 10% of the
voting power of all classes of shares of the Company, the exercise price of any
option granted must be at least 110% of the fair market value of the Common
Shares on the grant date and the term of such option may not exceed five years.
No incentive options may be granted to a participant which, when aggregated with
all other incentive options granted to that participant, would have an aggregate
fair market value in excess of $100,000 becoming exercisable in any calendar
year.
 
     No option may be transferred by the optionee other than by will or the laws
of descent and distribution. During the lifetime of an optionee, only the
optionee may exercise an option. An option is exercisable on or after each
vesting date in accordance with the terms set forth in the option agreement.
Incentive options are exercisable only during the optionee's employment by the
Company, and for a period of up to 90 days after the termination of the
optionee's employment.
 
     The Share Incentive Plan is also administered by the Compensation
Committee, which in general is responsible for determining the type, amount and
terms of any consideration awarded to a recipient. Under the Share Incentive
Plan, any options granted to a recipient are exercisable in accordance with the
terms of the agreement governing the grant. If the option is an incentive stock
option, those terms must be consistent with the requirements of the Code, as
amended, and applicable regulations, including the requirement that the option
price not be less than the fair market value of the Common Shares on the date of
the grant. If the option is not an incentive stock option, the option price may
be any price determined by the Compensation Committee.
 
     In addition to incentive stock options and non-incentive stock options, the
Compensation Committee may award other types of incentive compensation under the
Share Incentive Plan. Such additional incentive compensation can include stock
awards, stock appreciation rights (which entitle the holder of the right upon
 
                                       59
<PAGE>   61
 
exercise thereof to receive payment from the Company of an amount equal in value
to the excess of the fair market value of the Company's Common Shares on the
date of exercise over the fair market value of the Company's Common Shares on
the date of grant or, if granted in connection with an option, the option price
per share under the option to which the stock appreciation right relates), cash
bonuses, performance-based awards (which are intended to qualify as
performance-based compensation under sec. 162(m) of the Code) and Common Shares
which are subject to a purchase agreement between the Company and the
prospective recipient.
 
     401(k) Plan. In 1990, the Company adopted a deferred compensation plan
under sec. 401(k) of the Code (the "401(k) Plan"). Each full-time employee who
has completed at least one year of service with the Company and has reached age
21 is eligible to make pre-tax elective deferral contributions of up to 20% of
their total compensation per plan year, subject to a specified maximum
contribution as determined by the Internal Revenue Service. The Company matches
the employee's contribution on a formula of $0.25 to the dollar, not to exceed
three percent of the employee's gross annual compensation. The vesting schedule
of the employer match is 33 1/3% per year, over three years. Any potential
forfeitures of the Company's portion of the contribution that do not become
vested are reallocated to the remaining employees in the 401(k) Plan based on
their account balance as a percentage of the whole.

                              CERTAIN TRANSACTIONS
 
     In July 1995, the Company entered into a research and development agreement
with the predecessor to Novartis. The collaboration was formed to evaluate the
potential for development of iontophoretic drug delivery systems for a number of
Novartis compounds for several therapeutic applications. In connection with the
collaboration, Novartis purchased a 20% equity interest in Dermion. Pursuant to
the R&D Agreements, as amended, Novartis is required to pay research costs under
the program and to make milestone payments if Dermion successfully completes
certain objectives. The R&D Agreements may be terminated by either party for any
reason upon six months notice. In addition, the Company granted Novartis a
perpetual, non-exclusive, royalty-bearing license to certain of the Company's
iontophoretic technology, as well as certain rights with respect to future
technology developed or acquired by the Company. In addition, the Company agreed
to certain limitations on its ability to develop products in certain Novartis
fields. Novartis also shares rights to all technology jointly developed pursuant
to the collaboration.
 
     Effective November 1, 1997, the Company, Dermion and Novartis amended the
terms of their relationship by entering into the 1997 Amendments. Under the 1997
Amendments, Novartis exchanged its 20% equity interest in Dermion for 238,541
Common Shares and warrants to acquire 18,750 Common Shares at an exercise price
of $21.60 per share. One-third of Novartis' warrants are currently exercisable.
Another one-third will be exercisable if Novartis commits to provide research
and development funding under the R&D Agreements for 1999. The balance will be
exercisable if Novartis commits to such funding for the year 2000. See
"Business -- Collaborative Relationships and Licenses."
 
     In March 1997, the Company entered into the Elan Agreements, an exclusive,
worldwide license to certain of Elan's iontophoretic drug delivery technology,
including over 250 issued and 47 pending United States and foreign patents, as
well as a significant body of know-how and preclinical and clinical study
results. The Company acquired the Elan technology by issuing Elan two promissory
notes, a $10.0 million note and a $5.0 million note. The Company also issued a
warrant to Elan to acquire 104,166 Common Shares at $21.60 per share and agreed
to pay Elan a royalty on the net revenues derived from sales of all of the
Company's products. The promissory notes each bear interest at the rate of prime
plus 1% (9 1/2% as of June 30, 1997), and the $5.0 million note is secured by
the technology rights the Company acquired in the transaction. Concurrently with
the closing of the Offering, Elan will acquire, directly from the Company in
private placement transactions, approximately 833,333 Common Shares (subject to
adjustment as described below) for approximately $10.2 million (the amounts
outstanding under the $10.0 million note) and approximately $5.1 million of
Common Shares at a price per share equal to the initial public offering price
hereunder. Simultaneously with such purchases, the Company will repay the Elan
Notes, including interest thereon. If the initial public offering price
hereunder is less than $12.00 per share, the number of Common Shares that Elan
will have the right to purchase for the approximately $10.2 million (the amounts
outstanding under the $10.0 million note) will be equal to approximately $10.2
million divided by the initial public offering price hereunder. If, as a result
of Elan's purchase of the Elan Shares, Elan's aggregate interest in the Common
Shares exceeds 19.9% of the outstanding Common Shares, Elan may elect to receive
non-voting preferred shares of the Company to the extent of such excess. Any
such preferred shares would rank pari passu with the Common Shares, be
non-voting and convertible into Common Shares initially on a one-for-one basis.
See "Risk Factors -- Potential Dilution; Absence of Dividends" and "Transactions
Related to the Offering."

COMMON SHARES
 
     Subject to preferences that may be applicable to any then outstanding
Preferred Shares, holders of Common Shares are entitled to receive, ratably,
such dividends as may be declared by the Board of Directors out of funds legally
available therefore. In the event of a liquidation, dissolution or winding up of
the Company, holders of the Common Shares are entitled to share ratably in all
assets remaining after the payment of liabilities and the liquidation preference
of any then outstanding Preferred Shares. Holders of Common Shares have no
preemptive rights and no right to convert their Common Shares into any other
securities. There are no redemption or sinking fund provisions applicable to the
Common Shares. All outstanding Common Shares are, and all Common Shares to be
outstanding upon completion of the Offering will be, fully paid and
nonassessable. The holders of Common Shares are entitled to one vote for each
share held of record on all matters submitted to a vote of shareholders. The
Company has not paid, and does not intend to pay, cash dividends on the Common
Shares for the foreseeable future.
 
PREFERRED SHARES
 
     As of November 1, 1997, there were 28,800 Series C Preferred Shares issued
and outstanding. The Series C Preferred Shares are subject to mandatory
conversion, on a share-for-share basis, into Common Shares upon the closing of
an initial public offering and will be converted in connection with the closing
of the Offering.
 
     The Board of Directors will have the authority to issue Preferred Shares in
one or more series and to affix the rights, preferences, privileges and
restrictions thereof, including dividend rights, conversion rights, voting
rights, redemption terms, liquidation preferences and the number of shares
constituting any series, without any further vote or action by the shareholders.
The issuance of Preferred Shares in certain circumstances may have the effect of
delaying or preventing a change in control of the Company. The issuance of
Preferred Shares with voting and conversion rights may adversely affect the
voting power and rights of the holders of Common Shares.
 
WARRANTS
 
     The Company has issued four warrants which, in the aggregate, entitle the
holders thereof to acquire 169,791 Common Shares. On November 1, 1997, the
Company issued Novartis warrants to acquire, through November 1, 2002, 18,750
Common Shares at an exercise price of $21.60 per share. One-third of the
Novartis warrants are currently exercisable. Another one-third of the warrants
are exercisable if Novartis agrees to certain funding commitments under its
agreements with the Company for 1999, and the other one-third of the warrants is
exercisable if Novartis makes such funding commitments for the year 2000. Under
the Elan Agreements, Elan was issued a warrant to acquire, through April 19,
2002, 104,166 Common Shares at an exercise price of $21.60 per share. On
December 1, 1996, the Company issued ACH a warrant to acquire, through December
1, 2003, 44,791 Common Shares at an exercise price of $8.88 per share. On June
25, 1992, the Company issued a warrant to Silicon Valley Bank to acquire,
through June 24, 2002, 2,083 Common Shares at an exercise price of $4.80 per
share.
 
     In connection with the closing of the Offering, the Company has agreed to
issue to the Representatives, warrants to purchase, after the first anniversary
of the date hereof, an aggregate of 170,000 Common Shares at a price per share
equal to (i) 125% of the initial public offering price set forth on the cover
page of this Prospectus after the first anniversary of the date of this
Prospectus or (ii) 150% of the initial public offering price set forth on the
cover page of this Prospectus after the third anniversary of the date of this
Prospectus. The Representatives's Warrants expire on the fifth anniversary of
the date of this Prospectus.
 
ANTI-TAKEOVER EFFECT OF UTAH LAW AND CERTAIN PROVISIONS OF THE ARTICLES OF
INCORPORATION
 
     The Company's Articles of Incorporation require that any action required or
permitted to be taken by shareholders of the Company must be effected at a duly
called annual or special meeting of shareholders. Utah law provides that any
action which may be taken at any annual or special meeting of shareholders may
be taken without a meeting and without prior notice, if one or more consents in
writing, setting forth the action
 
                                       64
<PAGE>   66
 
to be taken, are signed by the holders of outstanding shares having at least the
minimum number of votes that would be necessary to take the action at a meeting
at which all shares entitle to vote on the matter were present and voted. This
provision generally applies to all Utah corporations formed after 1992 and all
Utah corporations formed before 1992 that have amended their articles of
incorporation to provide for actions by consent. The Company is not entitled to
take advantage of that consent provision because it was formed prior to 1992 and
its shareholders have not amended its Articles of Incorporation to allow consent
actions. Special meetings of the shareholders of the Company may be called only
by the Board of Directors, the Chief Executive Officer of the Company or by any
person or persons holding shares representing at least 10% of the outstanding
capital stock. See "Management -- Executive Officers, Directors and Key
Employees."
 
     Utah has adopted legislation which is designed to delay the ultimate
success of a hostile tender offer for shares of a public company until that
tender offer has been approved by a majority of the shareholders. The
legislation applies to all corporations which have not opted out of its
provisions and which have more than 100 shareholders, maintain their principal
place of business or principal office in the State of Utah and where either 10%
or more of the corporation's shareholders reside in Utah or more than 10% of its
outstanding shares are owned by Utah residents. Under the terms of the Company's
Bylaws, the Company has opted out of these provisions.
 
     The Company's Articles of Incorporation provide for the division of the
Board of Directors into three classes, as nearly equal in size as possible, with
staggered three year terms. See "Management." In addition, the Articles of
Incorporation provide that directors may be removed only for cause and only by
an affirmative vote of the holders of two-thirds of the Common Shares entitled
to vote. Further, any vacancy on the Board of Directors, however occurring,
including by reason of an increase in the number of persons comprising the Board
of Directors, may only be filled by vote of a majority of the directors then in
office. These provisions could have the effect of making it more difficult for a
third party to acquire, or of discouraging a third party from acquiring, control
of the Company.
 
REGISTRATION RIGHTS
 
     Pursuant to the Elan Agreements, at any time following the Offering, Elan
has the right, on not more than two occasions and subject to certain

acquire upon exercising its warrant. The Elan Agreements also provide that, if
the Company proposes to file a registration statement under the Securities Act
with respect to an offering by the Company. Elan will be entitled to include all
or part of its shares in that registration, subject to the right of the managing
underwriter to exclude shares from registration to the extent their inclusion
would adversely affect the marketing of the shares to be sold. In connection
with the Offering, Elan has agreed not to sell or otherwise dispose of its
shares for a period of 180 days following the Offering. See "Shares Eligible for

TRANSFER AGENT AND REGISTRAR
 
     American Securities Transfer & Trust, Inc. will be the transfer agent and

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Offering, the Company will have outstanding an
aggregate of 6,360,204 Common Shares. In addition, the Company has reserved for
issuance 679,303 shares issuable upon exercise of outstanding options and
warrants, including the Representatives' Warrants. The 1,700,000 Common Shares
offered hereby will be freely transferable without restriction or further
registration under the Securities Act, except for shares which may be acquired
by "affiliates" of the Company as that term is defined in Rule 144 under the
Securities Act. The remaining Common Shares held by existing shareholders are
"restricted securities" as that term is defined in Rule 144. Restricted
securities may be sold in the public market only if they are registered or if
they qualify for exemption from registration under Rules 144 or 701 under the
Securities Act or otherwise. Pursuant to certain "lock-up" agreements, the
Company's directors, officers and certain of its shareholders who collectively
hold an aggregate of 4,560,934 Common Shares, together with the Company, have
agreed, for a period of 180 days following the date of this Prospectus, not to
offer, pledge, sell, contract to sell, grant any option for the sale of, or
otherwise dispose of, directly or indirectly, any Common Shares without the
prior written consent of EVEREN Securities, Inc. Following the lock-up periods,
approximately 1,903,533 Common Shares will be eligible for sale in the public
market without restriction under Rule 144(k) and an additional 79,808 Common
Shares will be eligible for sale subject to certain volume, manner of sale and
other limitations under Rule 144. Of the approximately 76,418 restricted shares
held by existing shareholders of the Company not subject to lock-up agreements,
all such Common Shares will be eligible for immediate sale in the public market
without restriction under Rule 144(k). In addition, holders of stock options or
warrants exercisable for an aggregate of approximately 220,227 Common Shares
have entered into agreements prohibiting sale of the underlying Common Shares
for 180 days following the date of this Prospectus.
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including an affiliate, who has beneficially owned
shares for at least one year is entitled to sell, within any three-month period
commencing 90 days after the date of this prospectus, a number of shares that
does not exceed the greater of (i) 1% of the then outstanding Common Shares
(63,602 shares immediately after the Offering) or (ii) the average weekly
trading volume in the Common Shares during the four calendar weeks preceding
such sale, subject to the filing of a Form 144 with respect to such sale and
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 90 days
preceding a sale, and who has beneficially owned the shares proposed to be sold
for at least two years, would be entitled to sell such shares under Rule 144(k)
without regard to the volume, manner of sale and other limitations described
above.
 
     Any employee or consultant to the Company who purchased his or her shares
pursuant to a written compensatory plan or contract is entitled to rely on the
resale provisions of Rule 701, which permit non-affiliates to sell their Rule
701 shares without having to comply with the public information, holding-period,
volume-limitation or notice provisions of Rule 144 and permit affiliates to sell
their Rule 701 shares without having to comply with the Rule 144 holding period
restrictions, in each case commencing 90 days after the date of this Prospectus.
 
     The holders of 4,036,010 Common Shares and warrants to purchase 337,708
Common Shares have certain registration rights. See "Description of Capital
Shares -- Registration Rights."

</TABLE>
 
     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent, including the absence
of any material adverse change in the Company's business and the receipt of
certain certificates, opinions and letters from the Company and its counsel and
independent auditors. The nature of the Underwriters' obligation is such that
they are committed to purchase all Common Shares offered hereby if any such
shares are purchased.
 
     The Underwriters propose to offer the Common Shares to the public at the
public offering price set forth on the cover page of this Prospectus, and to
certain dealers at such price less a concession not in excess of $          per
share. The Underwriters may allow to selected dealers and such dealers may
reallow a concession not in excess of $          per share to certain other
dealers. After the public offering of the Common Shares, the offering price and
other selling terms may be changed by the Representatives.
 
     The Company has granted to the Underwriters an option, exerciseable at any
time during the 30-day period after the date of this Prospectus, to purchase up
to an additional 255,000 Common Shares at the initial public offering price set
forth on the cover page of this Prospectus, less underwriting discounts and
commissions. The Underwriters may exercise such option solely for the purpose of
covering over-allotments, if any, in connection with the Offering. To the extent
the option is exercised, each Underwriter will be obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares as the number of Common Shares set forth next to such Underwriter's name
in the preceding table bears to the total number of shares listed in the table.
 
     The Company has agreed to issue to the Representatives warrants to
purchase, after the first anniversary of the date hereof, up to an aggregate of
170,000 Common Shares, at a price equal to (i) 125% of the initial public
offering price set forth on the cover page of this Prospectus after the first
anniversary of the date of this Prospectus or (ii) 150% of the initial public
offering price set forth on the cover page of this Prospectus after the third
anniversary of the date of this Prospectus. Holders of the Representatives'
Warrants have been granted certain demand and piggy-back registration rights
under the Securities Act with respect to the securities issuable upon exercise
of the Representatives' Warrants. See "Description of Shares -- Registration
Rights" and "Shares Eligible For Future Sale." The Representatives' Warrants
expire on the fifth anniversary of the date of this Prospectus.
 
     The Company has also granted the Representatives a nonaccountable expense
allowance of $245,000.
 
     The offering of the Common Shares is made for delivery when, as and if
accepted by the Underwriters and subject to prior sale and to withdrawal,
cancellation or modification of the Offering without notice. The Underwriters
reserve the right to reject an order for the purchase of Common Shares in whole
or in part.
 
     In connection with the Offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Common Shares. Specifically, the Underwriters may over-allot the Offering,
creating a syndicate short position. In addition, the Underwriters may bid for
and purchase Common Shares in the open market to cover syndicate short positions
or to stabilize the price of the Common Shares. Finally, the underwriting
syndicate may reclaim selling concessions from syndicate members in the
Offering, if the syndicate repurchases previously distributed Common Shares in
syndicate covering transactions, in stabilization transactions or otherwise. Any
of these activities may stabilize or maintain the market price of the
 
                                       68
<PAGE>   70
 
Common Shares above independent market levels. The Underwriters are not required
to engage in these activities, and may end any of these activities at any time.
 
     The Representatives have informed the Company that the Underwriters do not
intend to confirm sales to accounts over which they exercise discretionary
authority.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make in respect thereof.
 
     The executive officers, directors and certain employees of the Company and
certain other shareholders have agreed that they will not, without the prior
written consent of EVEREN Securities, Inc., offer, sell or otherwise dispose of
any Common Shares, options or warrants to acquire Common Shares or securities
exchangeable for or convertible into Common Shares for a period of 180 days
after the day of this Prospectus. The Company has agreed that it will not,
without the prior written consent of EVEREN Securities, Inc., offer, sell,
contract, grant any option to purchase or otherwise dispose of any Common
Shares, options or warrants to acquire Common Shares or securities exchangeable
for or convertible into Common Shares for a period of 180 days after the date of
this Prospectus, except for securities issued under its Stock Option Plan or
Share Incentive Plan, the Elan Agreements or upon exercise of currently
outstanding stock options or warrants. See "Shares Eligible for Future Sale."
 
     Prior to the Offering, there has been no public market for the Common
Shares. Consequently, the initial public offering price for the Common Shares
included in the Offering will be determined by negotiations between the Company
and the Representatives. Among the factors considered in determining such price
will be the history of and prospects for the Company's business and the industry
in which it competes, an assessment of the Company's management and the present
state the Company's development, its past and present operations and financial
performance, the prospects for future earnings of the Company, the present state
of the Company's research and development programs, the current state of the
economy in the United States and the current level of economic activity in the
industry in which the Company competes and in related or comparable industries,
and the current prevailing condition in the securities markets, including
current market valuations of publicly traded companies that are comparable to
the Company.
 
                                 LEGAL MATTERS
 
     The validity of the Common Shares offered hereby will be passed upon for
the Company by Parsons Behle & Latimer, Salt Lake City, Utah. Certain legal
matters in connection with the Offering will be passed upon for the Underwriters
by Skadden, Arps, Slate, Meagher & Flom (Illinois), Chicago, Illinois, which

matters regarding Utah law.

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

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Description of Business
 
     IOMED, Inc., a Utah corporation (the "Company"), develops, manufactures and
commercializes controllable drug delivery systems using iontophoresis
technology.
 
  Discontinued Operations
 
     On December 31, 1996, the Company sold the assets of its Motion Control
Division, which was engaged in the research, development, manufacture and sale
of advanced myoelectric prosthetic devices. Accordingly, the consolidated
statements of operations for the years ended June 30, 1996 and 1995 have been
restated to present the results of operations of the Motion Control Division as
a discontinued operation (see Note 4).
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its 80% owned subsidiary, Dermion, Inc. ("Dermion"). Dermion was formed in
April 1996 to conduct advanced research and development of iontophoretic drug
delivery systems on its own behalf and on behalf of third party clients. The
remaining 20% interest of Dermion is reflected as minority interest in the
accompanying financial statements. All significant intercompany transactions and
accounts have been eliminated.
 
  Cash Equivalents
 
     The Company considers all highly-liquid investments with maturities of
three months or less, when purchased, to be cash equivalents.
 
  Concentrations of Credit Risk
 
     The Company's financial instruments that are exposed to concentrations of
credit risk consist primarily of cash, cash equivalents and trade accounts
receivable. Cash and cash equivalents are held in federally insured financial
institutions or invested in high grade short-term commercial paper issued by
major United States corporations. The Company sells its products primarily to,
and has trade accounts receivable with, independent durable medical equipment
dealers in the United States and abroad. Less than 10% of product sales are to
foreign customers. As a general policy, collateral is not required for accounts
receivable; however, the Company maintains an allowance for losses based upon
expected collections of accounts receivable. Additionally, customers' financial
condition and credit worthiness are regularly evaluated and historical losses
have not been material. During the periods presented, none of the Company's
customers accounted for more than 10% of net product sales. Accordingly, the
Company considers concentrations of credit risk with respect to trade accounts
receivable to be low.
 
  Inventories
 
     Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out method. Inventories consisted of the following
and, at June 30, 1996, included $613,000 in inventory associated with the
Company's discontinued operations:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Equipment and Furniture
 
     Equipment and furniture are stated at cost. Depreciation and amortization
is computed using the straight-line method over estimated useful lives of three
to five years. Leasehold improvements are amortized over the term of the lease
or the useful life of the improvements, whichever is shorter. Equipment and
furniture consisted of the following and, at June 30, 1996, included $50,000 in
equipment net of accumulated depreciation associated with the Company's
discontinued operations:

</TABLE>
 
  Revenue Recognition
 
     Revenues on product sales are generally recognized upon shipment. Contract
research revenue and license fees are recognized as earned.
 
  Patent Development Costs
 
     In connection with its research and development efforts, the Company incurs
certain costs in the preparation, application, filing, maintenance and defense
of patents and trademarks. Where such costs primarily relate to patents and
trademarks covering technologies or products which are under development or in
the early stages of commercialization, the Company expenses such costs as
incurred.
 
  Stock Options
 
     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations in accounting for its employee stock options rather than
adopting the alternative fair value accounting provided for under FASB Statement
No. 123, Accounting for Stock-Based Compensation (SFAS 123). Under APB 25,
because the exercise price of the Company's share options equals the market
price of the underlying shares on the date of grant, the Company does not
recognize any compensation expense.
 
  Income Taxes
 
     The Company accounts for income taxes using the asset and liability method.
Under the asset and liability method, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities and
their respective tax bases, operating loss and tax credit carryforwards.
Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.
 
  Earnings (Loss) Per Share
 
     The Company's net income (loss) per share is based upon the weighted
average number of common shares outstanding during the periods. Common share
equivalents (stock options, warrants, convertible

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
preferred shares and convertible debt), as determined using the treasury stock
method, have been excluded from the computations in those periods where their
inclusion would have an antidilutive effect. Pursuant to the Securities and
Exchange Commission Staff Accounting Bulletin No. 83, shares and equivalent
shares issued by the Company at prices below the assumed public offering price
during the twelve-month period prior to the proposed offering have been included
in the calculation as if they were outstanding for all periods presented (using
the treasury stock method and using the assumed midpoint of the initial public
offering price range).
 
  New Accounting Pronouncements
 
     In 1997, the FASB issued three new statements, SFAS No. 128-Earnings per
Share, SFAS No. 130-Reporting Comprehensive Income and SFAS No. 131-Disclosures
about Segments of an Enterprise and Related Information. As of June 30, 1997,
these statements were either not effective or not yet adopted by the Company.
The Company believes the new standards will not have a material impact on the
Company's financial statements.
 
  Estimates
 
     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 at the date of the
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Reclassifications
 
     Certain reclassifications have been made to prior year financial statements
to conform to the financial statement presentation included herein.
 
 2. PURCHASE OF IN-PROCESS RESEARCH AND DEVELOPMENT
 
     In March 1997, the Company entered into agreements with Elan Corporation,
plc ("Elan"), an international developer of advanced drug delivery systems, to
obtain an exclusive, worldwide license for the commercial development of certain
of Elan's in-process research and development in the field of iontophoretic drug
delivery, including both issued and pending patents, know-how and clinical data.
Pursuant to the agreements, the Company paid Elan a one time fee of $15,000,000,
issued warrants to purchase up to 500,000 common shares at a price of $21.60 per
share and agreed to pay Elan certain royalties on net revenues derived from
sales of its iontophoretic drug delivery products. Both the number and share
price of the warrants are subject to adjustment for certain corporate
transactions. Payment of the fee was funded by the issuance of two subordinated
convertible notes to Elan in an aggregate principal amount of $15,000,000 (See
Notes 3 and 7).
 
 3. NON-RECURRING CHARGES
 
     The intended clinical applications, as well as alternative future
applications, of the technologies purchased from Elan (see Note 2) are in the
early stages of research, design and clinical development, subject to numerous
technological, regulatory, and commercial risks and, therefore, represent
in-process research and development. Accordingly, during fiscal 1997, the
Company recorded a non-recurring charge of $15,059,000 reflecting the write-off
of the in-process research and development purchased, including the fee and
related transaction costs.
 
     During fiscal 1996, a suit was filed against the Company by a competitor
alleging, among other things, that a recently introduced product of the Company
infringed upon the competitor's trade dress. In February 1996, a federal court
granted the plaintiff's request for a preliminary injunction. Thereupon, the

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
Company entered into a settlement agreement with the plaintiffs. The total costs
incurred in connection with the suit were approximately $430,000, which amount
includes legal fees, court costs and damages paid to the plaintiff, legal fees
incurred by the Company and inventory rework costs. The settlement agreement
will not have any material impact on the Company's ability to continue to
manufacture and sell its products, including the new product which gave rise to
the litigation.
 
 4. DISCONTINUED OPERATIONS
 
     In December 1996, the Company sold the assets of its Motion Control
Division, which was engaged in the research, development, manufacture and sale
of myoelectric prosthetic devices. In addition, the Company granted a worldwide,
exclusive license to certain patent rights covering the products manufactured by
the division to the purchaser. Proceeds from the sale were $1,000,000 and the
Company is entitled to receive royalties on future product sales of the
purchaser. There was no significant gain or loss recognized on the sale.
Included in accounts receivable at June 30, 1996 is $351,000 associated with the
Company's discontinued operations. The results of operations of the Motion
Control Division prior to its sale have been classified as discontinued
operations in the accompanying statements of operations. No interest expense has
been allocated to discontinued operations and both federal and state income
taxes have been calculated and allocated based upon statutory rates. A summary
of the results of discontinued operations is as follows:

 5. INVESTMENTS IN MARKETABLE DEBT SECURITIES
 
     Debt securities are classified as held-to-maturity when the Company has the
intent and ability to hold the security to maturity. Held-to-maturity securities
are stated at amortized cost, adjusted for amortization of premiums and
accretion of discounts to maturity, which approximates quoted fair market
values. Such amortization as well as interest earned is included in interest
income. As of June 30, 1996 and 1997, all investments were classified as
held-to-maturity and consisted of United States corporate securities totaling
$3,757,000 and $4,635,000, respectively, and are included with cash and cash
equivalents.
 
 6. ACCRUED LIABILITIES

     In 1995, the Company's board of directors approved management's plan to
consolidate the Company's operating facilities. Under the plan, certain office
facilities currently under lease through December 1999 have been left idle.
Accordingly, the Company recorded charges and accrued facilities costs in the
amount of $180,000 and $53,000 in 1995 and 1996, respectively, which represents
the total committed lease obligation for

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
the idle space, plus estimated maintenance and construction costs. At June 30,
1997, approximately $69,000 of these charges remained in accrued liabilities.
 
 7. SUBORDINATED, CONVERTIBLE DEBT
 
     In connection with the purchase of in-process research and development from
Elan (see Note 2), the Company issued two promissory notes to Elan, the A Note
and the B Note, in the amount of $10,000,000 and $5,000,000, respectively. Both
notes are subordinated to any existing or future indebtedness incurred to
finance working capital or the purchase of fixed assets in the normal course of
business. The carrying value of these notes approximates fair market value since
interest rates are based upon current market rates.
 
     The A Note accrues interest at prime plus one percent (9.5% at June 30,
1997), payable at maturity. Upon the completion of an initial registered public
offering of common shares or in any event on April 1, 1999, the note, together
with all accrued interest thereon, will be exchanged for common shares of the
Company. If the triggering event is an initial registered public offering, the
Company will issue 833,333 common shares, as adjusted for certain corporate
transactions, in exchange for the note. If an initial public offering is not
previously consummated, then on April 1, 1999, in exchange for the indebtedness
under the A Note, the Company will issue shares at an exchange price of $12.00
per share, which exchange price is subject to adjustment under certain
conditions.
 
     The B Note accrues interest at prime plus one percent (9.5% at June 30,
1997). The B Note plus any accrued and unpaid interest thereon will become due
and payable immediately upon the completion of an initial registered public
offering of common shares. If not pre-paid pursuant to an initial registered
public offering or otherwise, the B Note, becomes due and payable in five equal
installments of principal of $1,000,000 on each of the fifth, sixth, seventh,
eighth and ninth anniversaries of the note, together, in each case with any
accrued and unpaid interest thereon.
 
     In June 1993, the Company entered into a research and development agreement
with Laboratoires Fournier, a French pharmaceutical company ("Fournier") to
collaborate in the joint development and commercialization of certain drug
delivery systems. In connection with this transaction, in July 1993, the Company
borrowed $3,000,000 ($2,923,000, net of debt issuance costs) from Fournier
pursuant to a subordinated, convertible note. In March 1996, the companies
reached a mutual agreement to terminate their collaborative development efforts.
Among other things, the agreement provided for the conversion of the $3,000,000
subordinated, convertible note, at a conversion rate of $8.88 per share, into
337,838 common shares.
 
 8. COMMITMENTS
 
     The Company leases space and certain equipment under noncancellable
operating lease agreements that expire at various dates through December 1999.
Rental expense for such leases was $225,000, $227,000 and $218,000 for the years
ended June 30, 1995, 1996 and 1997, respectively. It is generally expected that,
in the normal course of business, operating leases that expire will be renewed
or replaced by other leases with similar terms. Future minimum lease payments
under noncancellable operating leases (with initial or remaining lease terms in
excess of one year) at June 30, 1997 were $86,000.
 
 9. ROYALTY AGREEMENTS
 
     The Company is the licensee under a royalty agreement with the University
of Utah Research Foundation. This agreement provides for the payment of
royalties to the licensor based upon net sales of the products under royalty
until the year 2006. Royalty expense in each of the three years in the period
ended June 30, 1997 was not material.

10. REDEEMABLE, CONVERTIBLE PREFERRED SHARES
 
     In connection with a reorganization of the Company in fiscal 1988, the
Company issued 878,254 shares of $.001 par value redeemable convertible
preferred shares in three series; Series A, Series B and Series C. Pursuant to
the terms of such preferred shares, the Series A shares were redeemed in equal
installments beginning in July 1992 through July 1996 at a redemption price of
$25.00 per share and the Series B shares (828,254 shares with a carrying value
of $1,500,000) were converted prior to July 15, 1996 into common shares on a
share for share basis at the equivalent of $1.811 per share.
 
     The Series C preferred shares outstanding as of June 30, 1997 are comprised
of 36,000 shares with an aggregate redemption value of $900,000. The Series C
preferred shares are redeemable at $25.00 per share in five equal annual
installments beginning in July 1997. Unless converted to common shares,
mandatory redemption requirements on the Series C preferred shares are $180,000
annually from 1998 through 2002. The Company may redeem all or part of the
preferred shares to the extent of its unreserved and unrestricted retained
earnings at any time prior to the required redemption dates.
 
     Prior to redemption, each share of the Series A, B and C preferred shares
either are, or were, as applicable, convertible on a share for share basis, at
the option of the holder, into common shares. The conversion ratio is subject to
adjustment based on the issue price of additional shares, options, or rights to
common shares issued. Each outstanding preferred share will automatically
convert to one common share upon the sale of common shares of the Company
pursuant to a registration statement under the Securities Act of 1933, the
public offering price of which is not less than $5.4331 per share and which
results in gross proceeds to the Company of at least $5,000,000.
 
     Each share of the Series A, B and C preferred shares has a voting right
equal to one vote for each common share into which the preferred share could be
converted as outlined above. The holders of the preferred shares have voting
rights and powers equal to those of the holders of common shares and vote with
the holders of common shares and not as a separate class. Under no circumstances
are the holders of any series of preferred shares entitled to vote separately on
any matter.
 
     Dividends are non-cumulative and are to be paid on the preferred shares
only as authorized by the Board of Directors. In the event of liquidation of the
Company, each outstanding preferred share converts into one common share. No
dividend (other than a dividend payable solely in common shares) may be declared
or paid on common shares unless an equal or greater dividend per share has first
been declared and paid on each preferred share. Each preferred share, regardless
of its series, must be paid the same dividend per share. No dividends have been
declared or paid to date.
 
11. RESEARCH & DEVELOPMENT
 
     In July 1995, the Company entered into an interim research and development
agreement with Ciba-Geigy Corporation ("Ciba"), an affiliate of a Swiss
pharmaceutical company, to evaluate the feasibility of delivering certain Ciba
compounds using the Company's iontophoretic drug delivery technologies. In March
1996, this interim agreement was superseded by a long-term research and
development agreement with Ciba. In conjunction with the research and
development agreement, the Company formed Dermion, a wholly-owned subsidiary
established to conduct advanced iontophoretic drug delivery systems development.
The Company contributed cash, fixed assets and non-exclusive licenses to certain
technology, valued at a historical cost of approximately $1,300,000 to Dermion,
in exchange for common shares. Concurrently, Ciba acquired a 20% equity interest
in Dermion for $1,000,000 in cash. Pursuant to a separate shareholder's
agreement, Ciba is entitled to a premium of up to $1,250,000 in the event of a
change in control of Dermion.
 
     Ciba-Geigy Corporation and Sandoz Corporation merged and, as a result,
formed Novartis Pharmaceuticals Corporation.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     Currently, the term of the agreement extends through December 31, 1998. The
agreement automatically renews for additional one year terms, unless terminated,
by either party, with written notice six months prior to any anniversary date.
During the term of the research and development agreement, Novartis is obligated
to provide Dermion with research funding for the development of proprietary
iontophoretic drug delivery systems designed to deliver Novartis compounds.
Also, during the term of the agreement, Novartis has certain rights to the
Company's technologies for certain specific therapeutic indications using
Novartis proprietary drugs or specified generic compounds. The agreement further
provides that Dermion will be entitled to milestone payments upon the
achievement of certain performance targets and to future royalties on Novartis'
sales of products developed pursuant to the research. Dermion is currently
devoting the majority of its research and development capabilities to the
development of these systems for Novartis. Research funding payments and license
fees paid pursuant to the agreement with Novartis totaled $2,409,000 and
$1,750,000, respectively, in fiscal years ended June 30, 1996 and 1997. As of
June 30, 1997, the Company had a receivable, in the amount of $301,000, due from
Novartis, for research services rendered, which is included in accounts
receivable in the accompanying balance sheet.
 
12. EMPLOYEE BENEFIT PLAN
 
     The Company has established a 401(k) savings plan for its full-time
employees. The Company makes a matching contribution based on a percentage of
the contributions of participating employees. The Company contributed
approximately $24,000 during each of the years ended June 30, 1995 and 1996 and
approximately $19,000 during fiscal 1997.
 
13. INCOME TAXES
 
     Deferred taxes result from differences in the carrying value of various
assets and liabilities between income tax reporting and financial reporting
purposes. These differences arise from differing depreciation methods, and other
reserves that are deductible in different periods for tax and financial
reporting purposes.
 
     The approximate tax effect of temporary differences, net operating loss
carryforwards and tax credit carryforwards as of June 30, 1997 and 1996 is as
follows:

     As of June 30, 1997, the Company had approximately $4,147,000 in federal
and state net operating loss carryforwards, and $577,000 in federal tax credit
carryforwards, that expire from 2001 through 2012. Utilization of the Company's
net operating loss and credit carryforwards is limited to the future taxable
income of the Company. Under the "change of ownership" provisions of the
Internal Revenue Code, utilization of these net operating loss and credit
carryforwards may be subject to substantial annual limitation.
 
14. STOCK OPTIONS AND WARRANTS
 
     The Company has an Employee Stock Option Plan (the Plan) for which 520,833
common shares have been reserved. The Plan allows grants of incentive options
and nonqualified options to purchase common shares at a price that is not less
than the fair market value on the date of grant. The option price and dates the
options become exercisable and expire are determined by the Board of Directors
on an option-by-option basis.
 
     Pro forma information regarding net income and earnings per share has been
determined as if the Company had accounted for its employee stock options under
the fair value method. The fair value of these options was estimated at the date
of grant using a Minimum Value option pricing model with the following weighted
average assumptions for fiscal years ended June 30, 1996 and 1997: risk-free
interest rate of approximately 6.4% and 6.3%; dividend yield of 0%; and a
weighted-average expected life of the option of 6 years.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized over the options' vesting period. Because the effect of
SFAS No. 123-Accounting for Stock Based Compensation is prospective, the initial
impact on pro forma net income (loss) may not be representative of compensation
expense in future years. The effect on the Company's pro forma results for each
of the fiscal years ended June 30, 1996 and 1997 was not material (less than
$0.05 per share).

 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Description of Business
 
     IOMED, Inc., a Utah Corporation (the "Company"), develops, manufactures and
commercializes controllable drug delivery systems using proprietary
iontophoretic technology. Iontophoresis is a method of enhancing and controlling
the transport of drugs through the skin utilizing a low level electrical
current.
 
  Discontinued Operations
 
     On December 31, 1996, the Company sold the assets of its Motion Control
Division, which was engaged in the research, development, manufacture and sale
of advanced myoelectric prosthetic devices. Accordingly, the consolidated
statement of operations for the three months ended September 30, 1996 presents
the results of operations of the Motion Control Division as a discontinued
operation. There were no remaining assets or liabilities related to discontinued
operations reflected in the financial statements as of September 30, 1997 or
June 30, 1997.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its 80% owned subsidiary Dermion, Inc. ("Dermion.") Dermion was formed in
April 1996 to conduct advanced research and development of iontophoretic systems
on its own behalf and on behalf of third party clients. All significant
intercompany transactions and accounts have been eliminated.
 
  Basis of Presentation
 
     In the opinion of management, the accompanying condensed consolidated
financial statements contain all normal recurring adjustments necessary to
present fairly the financial position of the Company as of September 30, 1997
and the results of its operations and cash flows for the three month periods
ended September 30, 1997 and 1996. The operating results for the interim periods
are not necessarily indicative of the results for a full year. These statements
should be read in conjunction with the Company's audited consolidated financial
statements for the year ended June 30, 1997, included elsewhere in this
prospectus.
 
  Earnings (Loss) Per Share
 
     The Company's net income (loss) per share is based upon the weighted
average number of common shares outstanding during the periods. Common stock
equivalents (stock options, warrants, convertible preferred stock and
convertible debt), as determined using the treasury stock method, have been
included in such computations for the three month period ended September 30,
1996 and, except as noted below, have been excluded from the computations in the
three month period ended September 30, 1997 where their inclusion would have an
antidilutive effect.
 
     Pursuant to the Securities and Exchange Commission Staff Accounting
Bulletin No. 83, shares and equivalent shares issued by the Company at prices
below the assumed public offering price during the twelve-month period
immediately prior to the proposed public offering have been included in the
calculation of earnings per share (using the treasury stock method and using the
midpoint of the initial public offering range), as if they had been outstanding
for all periods presented, including periods in which such securities have an
antidilutive effect. Additional SAB No. 83 shares included in the computation of
per share amounts were 15,130 and 52,332 for the three month periods ended
September 30, 1997 and 1996, respectively.

  3. DISCONTINUED OPERATIONS
 
     In December 1996, the Company sold the assets of its Motion Control
Division which was engaged in the research, development, manufacture and sale of
myoelectric prosthetic devices. In addition, the Company granted a worldwide,
exclusive license to certain patent rights covering the products manufactured by
the division to the purchaser. Proceeds from the sale were $1,000,000 and the
Company is entitled to receive royalties on future product sales of the
purchaser. There was no significant gain or loss recognized on the sale. The
results of operations of the Motion Control Division prior to its sale have been
classified as discontinued operations in the accompanying statements of
operations. No interest expense has been allocated to discontinued operations
and both federal and state income taxes have been calculated and allocated based
upon statutory rates. A summary of the results of discontinued operations is as
follows:

 4. SUBSEQUENT EVENTS
 
  Initial Public Offering
 
     On October 3, 1997, the Company filed a registration statement on Form S-1
with the Securities and Exchange Commission pursuant to which the Company
intends to consummate an initial public offering of newly issued common shares.
 
  Reverse Stock Split
 
     On November 7, 1997, pursuant to a vote of the shareholders, the Company
effected a one for 4.8 reverse share split for each common and preferred share
then outstanding and amended and restated its Articles of Incorporation and
Corporate Bylaws. Among other things, these amendments changed the par value of
the Company's common shares from $0.001 per share to no par value common shares;
increased the number of authorized common shares from 40,000,000 shares to
100,000,000 shares; and increased the number of authorized preferred shares from
4,215,618 shares to 10,000,000 shares. For comparative purposes, all share
amounts in the accompanying financial statements and related footnotes have been
retroactively restated to reflect the effects of the reverse stock split and the
increases in the authorized shares of the Company's common and preferred shares.

  Novartis Exchange Agreement
 
     Effective November 1, 1997, the Company entered into an Exchange Agreement
with Novartis Pharmaceuticals Corporation. Among other things, the Exchange
Agreement provided for the exchange of Novartis' 20% minority interest in
Dermion, the Company's research and development subsidiary, for 238,541 common
shares of the Company and warrants to purchase, under certain conditions,
through November 1, 2002, an additional 18,750 common shares at a price equal to
$21.60 per share, making Dermion a wholly owned subsidiary of Iomed, Inc. In
addition, the Company and Novartis amended their research and development
agreement to, among other things, expand Iomed's rights to conduct research and
development in areas other than in the areas of acute local inflamation and
local dermal anesthesia.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Company's Articles of Incorporation limit the personal liability of
directors and officers for monetary damages to the maximum extent permitted by
Utah law. Under Utah law, such limitations include monetary damages for any
action taken or failed to be taken as an officer or director except for (i)
amounts representing a financial benefit to which the person is not entitled,
(ii) liability for intentional infliction of harm on the Corporation or its
shareholders, (iii) unlawful distributions, or (iv) an intentional violation of
criminal law. The Articles of Incorporation also provide that the Company will
indemnify its directors and officers against any damages arising from their
actions as agents of the Company, and that the Company may similarly indemnify
its other employees and agents. The Company is also empowered under its Articles
of Incorporation to enter into indemnification agreements with its directors and
officers.
 
     The Company's Bylaws provide that, to the full extent permitted by the
Company's Articles of Incorporation and the Utah Revised Business Corporation
Act, the Company will indemnify (and advance expenses to) the Company's
officers, directors and employees in connection with any action, suit or
proceeding (civil or criminal) to which those persons are made party by reason
of their being a director, officer or employee). Any such indemnification will
be in addition to the advancement of expenses.
 
     The terms of the Company's Stock Option Plan provide that, to the fullest
extent permitted by the Company's Articles of Incorporation and Bylaws and by
Utah law, no member of the committee which administers the plan will be liable
for any action or omission taken with respect to the plan or any options issued
thereunder. The Plan also provides that no member of the Board of Directors will
be liable for any action or determination made in good faith with respect to the
Plan or any option granted thereunder.
 
     There is no pending litigation or proceeding involving a director, officer,
employee or other agent of the Company as to which indemnification is being
sought, nor is the Company aware of any pending or threatened litigation that
may result in claims for indemnification by any director, officer, employee or
other agent.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     The Company has entered into five transactions in the past three years
involving the issuance of its securities under certain transactional exemptions
of the Securities Act of 1933.
 
     On February 20, 1996, the Company issued to Laboratoires Fournier 337,837
Common Shares in conversion and satisfaction of a non-interest bearing
$3,000,000 promissory note sold to Laboratoires Fournier in 1993. On November
29, 1996, the Company issued 37,202 Common Shares to CHIC, an affiliate of CHCA,
for a total purchase price of $250,000. In connection with that transaction, on
December 1, 1996, the Company also issued to ACH, a subsidiary of CHCA, a
warrant to acquire up to 44,791 Common Shares at an exercise price of $8.88 per
share. In March 1997, the Company issued two promissory notes (one for $10.0
million and the other for $5.0 million) to Elan and delivered to Elan a warrant
to purchase 104,166 Common Shares in connection with the purchase of certain
technology from Elan. Effective November 1, 1997, the Company issued Novartis
238,541 Common Shares and warrants to acquire 18,750 Common Shares in connection
with the exchange by Novartis of its 20% equity interest in Dermion for an
equity position in the Company pursuant to the provisions of the 1997
Amendments.
 
     In connection with each of these isolated issuances of the Company's
securities, each purchaser of those securities represented and warranted to the
Company that it (i) was aware that the securities had not been registered under
federal securities laws, (ii) acquired the securities for its own account for
investment purposes and not with a view to or for resale in connection with any
distribution for purposes of the federal securities laws, (iii) understood that
the securities would need to be indefinitely held unless registered or an
exemption from registration applied to a proposed disposition, (iv) was aware
that the certificate representing the securities would bear a legend restricting
their transfer, and (v) was aware that there was no public market for the
securities. The Company believes that, in light of the foregoing, and in light
of the sophisticated nature of each of the acquirers, the sale of the Company's
securities to the respective acquirers did not constitute the sale of an
unregistered security in violation of the federal securities laws and
regulations by reason of the exemption provided under sec. 4(2) of the
Securities Act, and the rules and regulations promulgated thereunder.
 
     Concurrently with the closing of the Offering, Elan will acquire, directly
from the Company in private placement transactions, approximately 833,333 Common
Shares (subject to adjustment as described below) for approximately $10.2
million (the amount outstanding under the $10.0 million note) and approximately
$5.1 million of Common Shares at a price per share equal to the initial public
offering price hereunder. Simultaneously with such purchase, the Company will
repay the Elan Notes, including interest thereon. If the initial public offering
price hereunder is less than $12.00 per share, the number of Common Shares that
Elan will have the right to purchase for approximately $10.2 million (the amount
outstanding under the $10.0 million note) will be equal to approximately $10.2
million divided by the initial public offering price hereunder. Elan has
represented in the Elan agreements that it is aware that those Common Shares
will not be registered under federal securities laws, will acquire those Common
Shares for its own account and for investment purposes, understands that the
Common Shares will need to be held indefinitely unless registered or an
exemption from registration applies to any proposed disposition, and that the
certificates representing the shares will bear a restrictive legend. In light of
the foregoing, the Company believes that the acquisition of the approximately
833,333 Common Shares (subject to adjustment under certain circumstances) and
the approximately $5.1 million of Common Shares at a price per share equal to
the initial public offering price hereunder in private placement transactions
will not constitute the sale of an unregistered security in violation of federal
securities law by reason of the exemption provided under sec. 4(2) of the
Securities Act.

ITEM 17. UNDERTAKINGS
 
     The undersigned Registrant hereby undertakes that:
 
          (1) 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.
 
          (2) 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 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.
 
          (3) 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.
 
          (4) 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.

  As Representatives of the Several Underwriters

c/o  EVEREN SECURITIES, INC.
     77 West Wacker Drive
     31st Floor
     Chicago, Illinois  60601

Dear Sirs:

               Iomed, Inc., a Utah corporation (the "Company"), proposes to
issue and sell an aggregate of 1,700,000 common shares, without par value (the
"Initial Securities"), to the several Underwriters named in Schedule I hereto
(the "Underwriters") for whom EVEREN Securities, Inc. ("EVEREN"), Hanifen,
Imhoff Inc. and Wedbush Morgan Securities are acting as representatives (the
"Representatives"). In addition, solely for the purpose of covering
over-allotments, the Company proposes to grant to the several Underwriters, upon
the terms and conditions set forth in Section 2 hereof, an option to purchase up
to an additional 255,000 common shares of the Company (the "Option Securities").
The Company also proposes to issue and sell to the Representatives warrants (the
"Representatives' Warrants") pursuant to the Representatives' Warrant Agreement
between the Company and the Representatives for the purchase of an additional
170,000 common shares. The 170,000 common shares issuable upon exercise of the
Representatives' Warrants are herein referred to as the "Representatives'
Securities." The Initial Securities, the Option Securities and the
Representatives' Securities are hereinafter collectively referred to as the
"Securities." The Company's common


<PAGE>   2
shares, without par value, including the Securities, are hereinafter referred to
as the "Common Shares." The Company wishes to confirm as follows its agreements
with you and the other Underwriters on whose behalf you are acting in connection
with the several purchases by the Underwriters of the Securities:

        1.      REGISTRATION STATEMENT AND PROSPECTUS. The Company has prepared
and filed with the Securities and Exchange Commission (the "Commission") a
registration statement on Form S-1 (No. 333-____) covering the registration of
the Securities under the Securities Act of 1933, as amended (the "1933 Act"),
including the related preliminary prospectus, or prospectuses, and either (A)
has prepared and filed, prior to the effective date of such registration
statement, an amendment to such registration statement, including a final
prospectus or (B) if the Company has elected to rely upon Rule 430A ("Rule
430A") of the rules and regulations of the Commission under the 1933 Act (the
"1933 Act Regulations"), will prepare and file a prospectus, in accordance with
the provisions of Rule 430A and Rule 424(b) ("Rule 424(b)") of the 1933 Act
Regulations, promptly after execution and delivery of this Agreement.
Additionally, if the Company has elected to rely upon Rule 434 ("Rule 434") of
the 1933 Act Regulations, the Company will prepare and file a term sheet (a
"Term Sheet") in accordance with the provisions of Rule 434 and Rule 424(b),
promptly after execution and delivery of this Agreement. The information, if
any, included in such prospectus or in such Term Sheet, that was omitted from
such registration statement at the time it became effective but that is deemed
to be part of such registration statement at the time it becomes effective (a)
pursuant to paragraph (b) of Rule 430A, is referred to herein as the "Rule 430A
Information," or (b) pursuant to paragraph (d) of Rule 434, is referred to
herein as the "Rule 434 Information." Each prospectus used before the time such
registration statement became effective, and any prospectus that omitted, as
applicable, the Rule 430A Information or the Rule 434 Information that was used
after effectiveness and prior to the execution and delivery of this Agreement is
herein called a "preliminary prospectus." Such registration statement, including
the exhibits and schedules thereto, at the time it became effective and
including, if applicable, the Rule 430A Information or the Rule 434 Information,
is herein called the "Registration Statement." Any registration statement filed
pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the
"Rule 462(b) Registration Statement," and after such filing the term
Registration Statement shall include the Rule 462(b) Registration Statement. The
final prospectus in the form first furnished to the Underwriters for use in
connection with the offering of the Securities is herein referred to as the
"Prospectus." If Rule 434 is relied upon, the term "Prospectus" shall refer to
the



                                       2
<PAGE>   3

preliminary prospectus last furnished to the Underwriters in connection with the
offering of the Securities, together with the Term Sheet, and all references to
the date of the Prospectus shall mean the date of the Term Sheet.

        2.      AGREEMENTS TO SELL AND PURCHASE. Upon the basis of the
representations, warranties and agreements contained herein and subject to all
the terms and conditions set forth herein, the Company hereby agrees to issue
and sell to each Underwriter and each Underwriter agrees, severally and not
jointly, to purchase from the Company, at a purchase price of $     per share
(the "purchase price per share"), the number of Initial Securities set forth in
Schedule I opposite the name of such Underwriter under the column "Number of
Initial Securities to be Purchased from the Company" (or such number of Initial
Securities increased as set forth in Section 10 hereof).

        Upon the basis of the representations, warranties and agreements
contained herein and subject to all the terms and conditions set forth herein,
the Company hereby grants an option (the "over-allotment option") to the
Underwriters to purchase from the Company, at the purchase price per share, up
to an aggregate of 255,000 Option Securities. Option Securities may be purchased
solely for the purpose of covering over-allotments made in connection with the
offering of the Securities. Such option shall expire at 5:00 P.M., Chicago time,
on the 30th day after the date of this Agreement (or, if such 30th day shall be
a Saturday or Sunday or a holiday, on the next business day thereafter when the
New York Stock Exchange is open for trading). Such over-allotment option may be
exercised at any time or from time to time until its expiration. Upon any
exercise of the over-allotment option, each Underwriter, severally and not
jointly, agrees to purchase from the Company that proportion of the total number
of Option Securities as is equal to the percentage of Initial Securities that
such Underwriter is purchasing from the Company (or such number of Initial
Securities increased as set forth in Section 10 hereof), subject to such
adjustments as you may determine to avoid fractional shares.

        On the Closing Date, the Company shall issue and sell to the
Representatives, Representatives' Warrants at an aggregate purchase price of
$[______], which warrants shall entitle the holders thereof to purchase, after
the first anniversary date of this Prospectus, an aggregate of 170,000
Representatives' Securities at an exercise price equal to (i) one hundred
twenty-five percent (125%) of the initial public offering price of the Initial
Securities after the first anniversary date of the Prospectus and (ii) one
hundred fifty percent (150%) of the initial public offering price of the Initial
Securities after the third



                                       3
<PAGE>   4

anniversary of the date of the Prospectus. The Representatives' Warrants shall
expire on the fifth anniversary of the date of the Prospectus. The
Representatives' Warrant Agreement shall be substantially in the form filed as
Exhibit ___ to the Registration Statement. Payment for the Representatives'
Warrants shall be made on the Closing Date.

        3.      TERMS OF PUBLIC OFFERING. The Company has been advised by you
that the Underwriters propose to make a public offering of the Securities as
soon after the Registration Statement and this Agreement have become effective
as in your judgment is advisable and initially to offer the Securities upon the
terms set forth in the Prospectus.

        4.      DELIVERY OF THE SECURITIES AND PAYMENT THEREFOR. Delivery to the
Underwriters of and payment for the Initial Securities shall be made at the
office of Skadden, Arps, Slate, Meagher & Flom (Illinois), 333 West Wacker
Drive, Suite 2100, Chicago, Illinois 60606, at 9:00 A.M., Chicago time, on the
third (fourth, if the pricing occurs after 4:30 P.M. (Eastern Time) on any given
day) business day after the date hereof (unless postponed in accordance with the
provisions of Section 10 hereof) (the "Closing Date"). The place of closing for
the Initial Securities and the Closing Date may be varied by agreement among you
and the Company.

        Delivery to the Underwriters of and payment for any Option Securities to
be purchased by the Underwriters shall be made at the aforementioned office of
Skadden, Arps, Slate, Meagher & Flom (Illinois) at such time on such date (an
"Option Closing Date"), which may be the same as the Closing Date but shall in
no event be earlier than the Closing Date nor earlier than two nor later than
ten business days after the giving of the notice hereinafter referred to, as
shall be specified in a written notice from you on behalf of the Underwriters to
the Company of the Underwriters' determination to purchase a number, specified
in such notice, of Option Securities. The place of closing for any Option
Securities and the Option Closing Date for such Option Securities may be varied
by agreement between you and the Company.

        Certificates for the Initial Securities and for any Option Securities to
be purchased hereunder shall be registered in such names and in such
denominations as you shall request by written notice (it being understood that a
facsimile transmission shall be deemed written notice) prior to 9:30 A.M.,
Chicago time, on the second business day preceding the Closing Date or any
Option Closing Date, as the case may be. Such certificates shall be made
available to you in Chicago, Illinois or New York, New York, as



                                       4
<PAGE>   5

requested by you in the aforesaid notice, for inspection and packaging not later
than 9:30 A.M., Chicago time, on the business day next preceding the Closing
Date or an Option Closing Date, as the case may be. The certificates evidencing
the Initial Securities and any Option Securities to be purchased hereunder shall
be delivered to you on the Closing Date or the Option Closing Date, as the case
may be, against payment of the purchase price therefor by certified or official
bank check or checks payable in New York Clearing House (next day) funds to the
order of the Company. It is understood that each Underwriter has authorized you,
for its account, to accept delivery of, acknowledge receipt of, and make payment
of the purchase price for, the Initial Securities and the Option Securities, if
any, which it has agreed to purchase. EVEREN, individually and not as
representative of the Underwriters, may (but shall not be obligated to) make
payment of the purchase price for the Initial Securities or the Option
Securities, if any, to be purchased by any Underwriter whose check has not been
received by the Closing Date or the Option Closing Date, as the case may be, but
such payment shall not relieve such Underwriter from its obligations hereunder.

        5.      AGREEMENTS OF THE COMPANY. The Company covenants and agrees with
the several Underwriters as follows:

                a.      The Company will notify the Underwriters immediately,
and confirm the notice in writing, (i) of the effectiveness of the Registration
Statement and any amendment thereto, (ii) of the receipt of any comments from
the Commission, (iii) of any request by the Commission for any amendment to the
Registration Statement or any amendment or supplement to the Prospectus or for
additional information, (iv) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or the suspension of
qualification of the Securities for offering or sale in any jurisdiction or the
initiation of any proceedings for such purpose and (v) during the period when
the Prospectus is required to be delivered under the 1933 Act or Securities
Exchange Act of 1934, as amended (the "1934 Act"), of any change, or any event
or occurrence which could result in such a change, in the Company's condition,
financial or otherwise, or the earnings, business affairs or business prospects
of the Company or the happening of any event, including the filing of any
information, documents or reports pursuant to the 1934 Act, that makes any
statement of a material fact made in the Registration Statement or the
Prospectus (as then amended or supplemented) untrue or which requires the making
of any additions to or changes in the Registration Statement or the Prospectus
in order to state a material fact required by the 1933 Act or the 1933 Act
Regulations to be stated therein or necessary in order to make



                                       5
<PAGE>   6

the statements therein not misleading, or of the necessity to amend or
supplement the Prospectus to comply with the 1933 Act, the 1933 Act Regulations
or any other law. The Company shall use its best efforts to prevent the issuance
of any stop order or order suspending the qualification or exemption of the
Securities under any state securities or Blue Sky laws, and, if at any time the
Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, or any state securities commission or other regulatory
authority shall issue an order suspending the qualification or exemption of the
Securities under any state securities or Blue Sky laws, the Company shall use
every reasonable effort to obtain the withdrawal or lifting of such order at the
earliest possible time.

                b.      The Company will give the Underwriters notice of its
intention to prepare or file any amendment to the Registration Statement
(including any post-effective amendment), any Rule 462(b) Registration
Statement, any Term Sheet or any amendment or supplement to the Prospectus
(including any revised prospectus or Term Sheet and preliminary prospectus which
the Company proposes for use by the Underwriters in connection with the offering
of the Securities which differs from the prospectus on file at the Commission at
the time the Registration Statement becomes effective, whether or not such
revised prospectus or Term Sheet and preliminary prospectus is required to be
filed pursuant to Rule 424(b)), whether pursuant to the 1933 Act, the 1934 Act
or otherwise, will furnish the Underwriters with copies of any Rule 462(b)
Registration Statement, Term Sheet, amendment or supplement a reasonable amount
of time prior to such proposed filing or use, as the case may be, and will not
file any such Rule 462(b) Registration Statement, Term Sheet, amendment or
supplement or use any such prospectus to which the Underwriters or counsel for
the Underwriters shall object.

                c.      The Company has furnished or will deliver to the
Underwriters and their counsel, without charge, as many signed and conformed
copies of the Registration Statement as originally filed and of each amendment
thereto (including exhibits filed therewith or incorporated by reference
therein) as the Underwriters may reasonably request.

                d.      The Company will furnish to each Underwriter, without
charge, from time to time during the period when the Prospectus is required to
be delivered under the 1933 Act or the 1934 Act, such number of copies of the
Prospectus (as amended or supplemented) as such Underwriter may reasonably
request for the purposes contemplated by the 1933 Act, the 1934 Act, the 1933
Act



                                       6

Act Regulations so as to permit the completion of the distribution of the
Securities as contemplated in this Agreement and in the Prospectus. If at any
time when a prospectus is required by the 1933 Act, the 1934 Act, the 1933 Act
Regulations or the 1934 Act Regulations to be delivered in connection with sales
of the Securities, any event shall occur or condition shall exist as a result of
which it is necessary, in the opinion of counsel for the Underwriters or for the
Company, to amend the Registration Statement or amend or supplement the
Prospectus in order that the Prospectus will not include any untrue statements
of a material fact or omit to state a material fact necessary in order to make
the statements therein not misleading in the light of the circumstances existing
at the time it is delivered to a purchaser, or if it shall be necessary, in the
opinion of such counsel, at any such time to amend the Registration Statement or
amend or supplement the Prospectus in order to comply with the requirements of
the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and
file with the Commission, subject to Section 5(b), such amendment or supplement
as may be necessary to correct such statement or omission or to make the
Registration Statement or the Prospectus comply with such requirements and the
Company will furnish to the Underwriters such number of copies of such amendment
or supplement as the Underwriters may reasonably request.

                f.      During the period of five years hereafter, the Company
will furnish to you (i) as soon as available, a copy of each report of the
Company mailed to stockholders or filed with the Commission or the Nasdaq
National Market ("NASDAQ"), and (ii) from time to time such other information
concerning the Company as you may request.

                g.      The Company will use its best efforts, in cooperation
with counsel to the Underwriters, to qualify the Securities for offering and
sale under the applicable securities or Blue Sky laws of such states and other
jurisdictions of the United States as the Underwriters may designate and to
maintain such qualifications in effect for a period of not less than one year
from the later of the effective date of the Registration Statement and any Rule
462(b) Registration Statement; provided, however, that the Company shall not be
obligated to qualify as a foreign corporation in any jurisdiction in which it is
not so qualified. In each jurisdiction in which the Securities have been so
qualified, the Company will file such statements and reports as may be required
by the laws of such jurisdiction to continue such



                                       7
<PAGE>   8

qualification in effect for a period of not less than one year from the later of
the effective date of the Registration Statement and any Rule 462(b)
Registration Statement.

                h.      The Company will make generally available to its
security holders as soon as practicable, but not later than 45 days after the
close of the period covered thereby, an earnings statement (in form complying
with the provisions of Rule 158 of the 1933 Act Regulations) covering a
twelve-month period beginning not later than the first day of the Company's
fiscal quarter next following the "effective date" (as defined in said Rule 158)
of the Registration Statement.

                i.      The Company will use the net proceeds received by it
from the sale of the Securities in the manner specified in the Prospectus under
"Use of Proceeds."

                j.      If, at the time that the Registration Statement becomes
effective, any Rule 430A Information or Rule 434 Information shall have been
omitted therefrom, then immediately following the execution of this Agreement,
the Company will prepare, and file or transmit for filing with the Commission in
accordance with Rule 430A or Rule 434 and Rule 424(b), copies of a Prospectus or
Term Sheet containing such Rule 430A Information and Rule 434 Information,
respectively, or, if required by Rule 430A, a post-effective amendment to the
Registration Statement (including an amended Prospectus), containing such Rule
430A Information.

                k.      If the Company elects to rely upon Rule 462(b), the
Company shall both file a Rule 462(b) Registration Statement with the Commission
in compliance with Rule 462(b) and pay the applicable fees in accordance with
Rule 111 of the 1933 Act Regulations by the earlier of (i) 10:00 P.M. Eastern
Time on the date hereof and (ii) the time confirmations are sent or given, as
specified by Rule 462(b)(2).

                l.      The Company, during the period when the Prospectus is
required to be delivered under the 1933 Act or the 1934 Act, will file all
documents required to be filed with the Commission pursuant to Section 13, 14 or
15 of the 1934 Act within the time periods required by the 1934 Act and the 1934
Act Regulations.

                m.      During a period of 180 days from the date of the
Prospectus, the Company will not, without the prior written consent of EVEREN,
(i) offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase or otherwise



                                       8
<PAGE>   9

transfer or dispose of, directly or indirectly, any Common Shares or any
securities convertible into or exercisable or exchangeable for Common Shares or
file any registration statement under the 1933 Act with respect to any of the
foregoing or (ii) enter into any swap or any other agreement or any transaction
that transfers, in whole or in part, directly or indirectly, the economic
consequence of ownership of the Common Shares, whether any such swap or
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Shares or such other securities, in cash or otherwise. The foregoing
sentence shall not apply to (A) the Securities to be sold hereunder, (B) any
Common Shares issued by the Company upon the exercise of an option or warrant or
the conversion of security outstanding on the date hereof and referred to in the
Prospectus, (C) any Common Shares issued or options to purchase Common Shares

interim consolidated financial statements of the Company and Dermion, Inc. (the
"Subsidiary"), for any periods subsequent to the periods covered by the
financial statements appearing in the Registration Statement and the Prospectus.

conference with respect to the Company or the Subsidiary, the condition,
financial or otherwise, or the earnings, business affairs or business prospects

consent of the Representatives unless in the judgment of the Company and its
counsel, and after notification to the Representatives, such press release or
communication is required by law.

<PAGE>   10

                r.      The Company has not taken, nor will it take, directly or
indirectly, any action designed to, or that might reasonably be expected to,
cause or result in stabilization or manipulation of the price of the Common

        6.      REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
represents and warrants to each Underwriter that:

                a.      When the Registration Statement, any Rule 462(b)
Registration Statement and any post-effective amendment thereto becomes
effective, at the date of the Prospectus, if different, and at the Closing Date
and the Option Closing Date, as the case may be, the Registration Statement, the
Rule 462(b) Registration Statement and any amendments and supplements thereto
complied or will comply in all material respects with the requirements of the
1933 Act and the 1933 Act Regulations and did not and will not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading.
The Prospectus and any supplements or amendments thereto will not at the date of
the Prospectus, at the date of any such supplements or amendments, or at the
Closing Date or the Option Closing Date, if any, include an untrue statement of
a material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. If Rule 434 is used, the Company will comply with the
requirements of Rule 434 and the Prospectus shall not be "materially different,"
as such term is used in Rule 434, from the Prospectus included in the
Registration Statement at the time it became effective. The representations and
warranties in this subsection shall not apply to statements in or omissions from
the Registration Statement or Prospectus relating to any Underwriter made in
reliance upon and in conformity with information furnished to the Company in
writing by any Underwriter, through EVEREN expressly for use in the Registration
Statement or Prospectus. The Company has not distributed any offering materials
in connection with the offering or sale of the Securities other than the
Registration Statement, the preliminary prospectus, the Prospectus, the Term
Sheet, if applicable, or any other materials, if any, permitted by the 1933 Act
or the 1933 Act Regulations.

                b.      Each preliminary prospectus and the prospectus filed as
part of the Registration Statement as originally filed or as part of any
amendment thereto, or filed pursuant to Rule 424



                                       10
<PAGE>   11

under the 1933 Act, complied when so filed in all material respects with the
1933 Act Regulations.

                c.      The accountants who certified the financial statements
and supporting schedules included in the Registration Statement are independent
public accountants as required by the 1933 Act and the 1933 Act Regulations.

                d.      The financial statements included in the Registration
Statement and the Prospectus present fairly the consolidated financial position
of the Company and its Subsidiary as of the dates indicated and the results of
their operations for the periods specified; except as otherwise stated in the
Registration Statement, said financial statements have been prepared in
conformity with generally accepted accounting principles applied on a consistent
basis; and the supporting schedules included in the Registration Statement
present fairly the information required to be stated therein. The financial
information and statistical data set forth in the Prospectus are prepared on an
accounting basis consistent with such financial statements.

                e.      Since the respective dates as of which information is
given in the Registration Statement and the Prospectus, except as otherwise
stated therein, (i) there has been no material adverse change or any development
involving a prospective material adverse change in or affecting the condition,
financial or otherwise, or in the earnings, business affairs or business
prospects of the Company and the Subsidiary considered as one enterprise,
whether or not arising in the ordinary course of business, (ii) there have been
no transactions entered into by the Company or the Subsidiary, other than those
in the ordinary course of business, which are material with respect to the
Company, and (iii) there has been no dividend or distribution of any kind

existing as a corporation in good standing under the laws of the State of Utah
with corporate power and authority to own, lease and operate its properties and
to conduct its business as described in the Prospectus and to enter into and
perform its obligations under this Agreement; and the Company is duly qualified
as a foreign corporation to transact business and is in good standing in each
jurisdiction in which such qualification is required, whether by reason of the
ownership or leasing of property or the conduct of business, except where the
failure to so qualify



                                       11
<PAGE>   12

would not, singly or in the aggregate, have a material adverse effect on the
condition, financial or otherwise, or the earnings, business affairs or business
prospects of the Company and the Subsidiary considered as one enterprise.

                g.      The Subsidiary has been duly incorporated and is validly

its properties and to conduct its business as described in the Prospectus and is
duly qualified as a foreign corporation to transact business and is in good
standing in each jurisdiction in which such qualification is required, whether

business prospects of the Company and the Subsidiary considered as one
enterprise; all of the issued and outstanding capital stock of the Subsidiary
has been duly authorized and validly issued, is fully paid and non-assessable

pledge, lien, charge, encumbrance, claim or equity. There are no outstanding
subscriptions, options, warrants, commitments, convertible or exchangeable
securities or other rights granted by the Company or the Subsidiary to acquire
any shares of capital stock of or ownership interests in the Subsidiary and
there are no commitments, plans or arrangements to do so. Except with respect to
the Subsidiary, the Company does not own, directly or indirectly, any shares of
stock or any other equity or long-term debt securities of any corporation or
have any equity interest in any firm, partnership, joint venture, association or
other entity.

                h.      The authorized, issued and outstanding capital stock of
the Company is as set forth in the Prospectus under "Capitalization" (except for
subsequent issuances, if any, pursuant to this Agreement or pursuant to
reservations, agreements, employee or director benefit plans or the exercise of
convertible securities referred to in the Prospectus); the shares of issued and
outstanding capital stock of the Company have been duly authorized and validly
issued and are fully paid and non-assessable and have not been issued in
violation of or are not otherwise subject to any preemptive or other similar
rights; the Securities have been duly authorized for issuance and sale to the
Underwriters pursuant to this Agreement and the Representatives' Warrant
Agreement, when issued and delivered by the Company pursuant to this Agreement
or the Representatives' Warrant Agreement against payment of the consideration
set forth herein or therein, will be validly issued and fully paid and
non-assessable; the certificates evidencing the



                                       12
<PAGE>   13

Securities are in due and proper form under Utah law; the authorized capital
stock of the Company, including the Securities, conforms to all statements
relating thereto contained in the Prospectus; and the issuance of the Securities
is not subject to preemptive or other similar rights. There are no outstanding
subscriptions, options, warrants, convertible or exchangeable securities or
other rights granted to or by the Company to purchase Common Shares or other
securities of the Company and there are no commitments, plans or arrangements to
issue any Common Shares or any security convertible into or exchangeable for
Common Shares, in each case other than as described in the Prospectus.

                i.      Except as disclosed in the Registration Statement and
except as would not, singly or in the aggregate, reasonably be expected to have
a material adverse effect on the condition, financial or otherwise, or the
earnings, business affairs or business prospects of the Company and the
Subsidiary considered as one enterprise, (A) the Company and the Subsidiary are
each in compliance with all applicable Environmental Laws, (B) the Company and
its Subsidiary have all permits, authorizations and approvals required under any
applicable Environmental Laws and are each in compliance with the requirements
of such permits authorizations and approvals, (C) there are no pending or, to
the best knowledge of the Company, threatened Environmental Claims against the
Company or the Subsidiary and (D) to the best knowledge of the Company, under
applicable law, there are no circumstances with respect to any property or
operations of the Company or the Subsidiary that are reasonably likely to form
the basis of an Environmental Claim against the Company or the Subsidiary.

        For purposes of this Agreement, the following terms shall have the
following meanings: "Environmental Law" means any United States (or other
applicable jurisdiction's) Federal, state, local or municipal statute, law,
rule, regulation, ordinance, code, policy or rule of common law and any judicial
or administrative interpretation thereof, including any judicial or
administrative order, consent decree or judgement, relating to the environment,
health, safety or any chemical, material or substance, exposure to which is
prohibited, limited or regulated by any governmental authority. "Environmental
Claims" means any and all administrative, regulatory or judicial actions, suits,
demands, demand letters, claims, liens, notices of noncompliance or violation,
investigations or proceedings relating in any way to any Environmental Law.

                j.      Neither the Company nor the Subsidiary is in violation
of its charter or in default in the performance or observance of any material
obligation, agreement, covenant or



                                       13
<PAGE>   14

condition contained in any contract, indenture, mortgage, loan agreement, deed,
trust, note, lease, sublease, voting agreement, voting trust, or other
instrument or agreement to which the Company or the Subsidiary is a party or by
which it or any of them may be bound, or to which any of the property or assets
of the Company or the Subsidiary is subject; and the execution, delivery and
performance of this Agreement and the Representatives' Warrant Agreement and the
consummation of the transactions contemplated herein and therein and compliance
by the Company with its obligations hereunder and thereunder have been duly
authorized by all necessary corporate action and will not conflict with or
constitute a breach of, or default under, or result in the creation or
imposition of any lien, charge or encumbrance upon any property or assets of the
Company or the Subsidiary pursuant to, any contract, indenture, mortgage, loan
agreement, deed, trust, note, lease, sublease, voting agreement, voting trust or
other instrument or agreement to which the Company or the Subsidiary is a party
or by which it or any of them may be bound, or to which any of the property or
assets of the Company or the Subsidiary is subject, nor will such action result
in any violation of the provisions of the charter or bylaws of the Company or
the Subsidiary or any applicable statute, law, rule, regulation, ordinance,
decision, directive or order.

                k.      No labor dispute with the employees of the Company or
the Subsidiary exists or, to the best knowledge of the Company, is imminent; and
the Company is not aware of any existing or imminent labor disturbance by the
employees of any of its principal suppliers, manufacturers or contractors which
might, singly or in the aggregate, be expected to result in any material adverse
change in the condition, financial or otherwise, or in the earnings, business
affairs or business prospects of the Company and the Subsidiary considered as
one enterprise.

                l.      There is no action, suit or proceeding before or by any
court or governmental agency or body, domestic or foreign, now pending, or, to
the knowledge of the Company, threatened, against or affecting the Company or
the Subsidiary, which is required to be disclosed in the Registration Statement
(other than as disclosed therein), or which, singly or in the aggregate, might
result in any material adverse change in the condition, financial or otherwise,
or in the earnings, business affairs or business prospects of the Company and
the Subsidiary considered as one enterprise, or which, singly or in the
aggregate, might materially and adversely affect the properties or assets
thereof or which might materially and adversely affect the consummation of this
Agreement; all pending legal or governmental proceedings to which the Company or
the Subsidiary is a party or of which any of their



                                       14
<PAGE>   15

respective property or assets is the subject which are not described in the
Registration Statement, including ordinary routine litigation incidental to the
business, are, considered in the aggregate, not material; and there are no
contracts or documents of the Company or the Subsidiary which are required to be
filed as exhibits to the Registration Statement by the 1933 Act or by the 1933
Act Regulations which have not been so filed.

                m.      The Company and the Subsidiary own or are licensed to
use all patents, patent applications, inventions, trademarks, trade names,
applications for registration of trademarks, service marks, service mark
applications, copyrights, know-how, manufacturing processes, formulae, trade
secrets, licenses and rights in any thereof and any other intangible property
and assets (herein called the "Proprietary Rights") which are material to the
businesses of the Company and the Subsidiary as now conducted and as proposed to
be conducted, in each case as described in the Prospectus. The description of
the Proprietary Rights is correct in all material respects and fairly and
correctly describes the Company's and the Subsidiary's rights with respect
thereto. Except as described in the Prospectus, the Company does not have any
knowledge of, and the Company has not given or received any notice of, any
pending conflicts with or infringement of the rights of others with respect to
any Proprietary Rights or with respect to any license of Proprietary Rights. No
action, suit, arbitration, or legal, administrative or other proceeding, or
investigation is pending, or, to the best knowledge of the Company, threatened,
which involves any Proprietary Rights. Neither the Company nor the Subsidiary is
subject to any judgment, order, writ, injunction or decree of any court or any
Federal, state, local, foreign or other governmental department, commission,
board, bureau, agency or instrumentality, domestic or foreign, or any
arbitrator, or has entered into or is a party to any contract which restricts or
impairs the use of any such Proprietary Rights in a manner which would have a
material adverse effect on the use of any of the Proprietary Rights. To the best
knowledge of the Company, no Proprietary Rights used by the Company or the
Subsidiary, and no services or products sold by the Company or the Subsidiary,
conflict with or infringe upon any proprietary rights available to any third
party. Neither the Company nor the Subsidiary has received written notice of any
pending conflict with or infringement upon such third-party proprietary rights.
Neither the Company nor the Subsidiary has entered into any consent,
indemnification, forbearance to sue or settlement agreement with respect to
Proprietary Rights other than in the ordinary course of business. No claims have
been asserted by any person with respect to the validity of the Company's or the
Subsidiary's ownership or right to use the Proprietary Rights and, to the best
knowledge of



                                       15
<PAGE>   16

the Company, there is no reasonable basis for any such claim to be successful.
The Proprietary Rights are valid and enforceable and no registration relating
thereto has lapsed, expired or been abandoned or cancelled or is the subject of
cancellation or other adversarial proceedings, and all applications therefore
are pending and are in good standing. The Company and the Subsidiary have
complied, in all material respects, with their respective contractual
obligations relating to the protection of the Proprietary Rights used pursuant
to licenses. To the best knowledge of the Company, no person is infringing on or
violating the Proprietary Rights owned or used by the Company or the Subsidiary.

                n.      No registration, authorization, approval, qualification
or consent of any court or governmental authority or agency is necessary in
connection with the offering, issuance or sale of the Securities hereunder or
under the Representatives' Warrant Agreement, except such as may be required
under the 1933 Act or the 1933 Act Regulations or state securities or Blue Sky
laws (or such as may be required by the National Association of Securities
Dealers, Inc. ("NASD")).

                o.      The Company and the Subsidiary each possess and are
operating in compliance with all licenses, certificates, consents, authorities,
approvals and permits (collectively, "permits") from all state, Federal, foreign
and other regulatory agencies or bodies necessary to conduct the businesses now
operated by them, and neither the Company nor the Subsidiary has received any
notice of proceedings relating to the revocation or modification of any such
permit or any circumstance which would lead it to believe that such proceedings
are reasonably likely which, singly or in the aggregate, if the subject of an
unfavorable decision, ruling or finding, would materially and adversely affect
the condition, financial or otherwise, or the earnings, business affairs or
business prospects of the Company and the Subsidiary considered as one
enterprise.

                p.      Each of this Agreement and the Representatives' Warrant
Agreement has been duly executed and delivered by the Company and constitutes a
valid and binding obligation of the Company, enforceable against the Company in
accordance with its terms, except as rights to indemnity and contribution
hereunder may be limited by Federal or state securities laws or the public
policy underlying such laws.

                q.      Except as described in the Prospectus, there are no
persons with registration or other similar rights to have any



                                       16
<PAGE>   17

securities registered pursuant to the Registration Statement or otherwise
registered by the Company under the 1933 Act.

                r.      No order preventing or suspending the use of any
preliminary prospectus has been issued and no proceedings for that purpose are
pending, threatened, or, to the knowledge of the Company, contemplated by the
Commission; and to the best knowledge of the Company, no order suspending the
offering of the Securities in any jurisdiction designated by the Underwriters
pursuant to Section 5(g) of this Agreement has been issued and, to the best
knowledge of the Company, no proceedings for that purpose have been instituted
or threatened or are contemplated.

                s.      The Company and the Subsidiary each have good and
marketable title to their respective properties, free and clear of all material
security interests, mortgages, pledges, liens, charges, encumbrances, claims and
equities of record. The properties of the Company and the Subsidiary are, in the
aggregate, in good repair (reasonable wear and tear excepted), and suitable for
their respective uses. Any real properties held under lease by the Company and
the Subsidiary are held by them under valid, subsisting and enforceable leases
with such exceptions as are not material and do not interfere with the conduct
of the business of the Company and the Subsidiary considered as one enterprise.

                t.      The Company and the Subsidiary maintain a system of
internal accounting controls-sufficient to provide reasonable assurances that
(i) transactions are executed in accordance with management's general or
specific authorization, (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles and to maintain accountability for assets, (iii) access to
assets is permitted only in accordance with management's general or specific
authorization, and (iv) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

                u.      The Company and the Subsidiary have conducted and are
conducting their respective businesses in compliance with all applicable
Federal, state, local and foreign statutes, laws, rules, regulations,
ordinances, codes, decisions, decrees, directives and orders, except where the
failure to do so would not, singly or in the aggregate, have a material adverse
effect on the condition, financial or otherwise, or on the earnings, business
affairs or business prospects of the Company and the Subsidiary considered as
one enterprise.



                                       17
<PAGE>   18

                v.      To the best of the Company's knowledge, neither the
Company nor the Subsidiary nor any employee or agent of the Company or the
Subsidiary has made any payment of funds of the Company or to Subsidiary or
received or retained any funds in violation of any law, rule or regulation,
which payment, receipt or retention of funds is of a character required to be
disclosed in the Prospectus.

                w.      The Company is not now, and after sale of the Securities
to be sold by it hereunder and application of the net proceeds from such sale as
described in the Prospectus under the caption "Use of Proceeds" will not be, an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

                x.      All offers and sales of capital stock of the Company
prior to the date hereof were at all relevant times duly registered or exempt
from the registration requirements of the 1933 Act and were duly registered or
subject to an available exemption from the registration requirements of the
applicable state securities or Blue Sky laws.

                y.      The Common Shares are registered pursuant to Section
12(g) of the 1934 Act. The Securities have been duly authorized for quotation on
NASDAQ. The Company has taken no action designed to, or likely to have the
effect of, terminating the registration of the Common Shares under the 1934 Act
or delisting the Common Shares from NASDAQ, nor has the Company received any
notification that the Commission or NASDAQ is contemplating terminating such
registration or listing.

                z.      Neither the Company nor, to its knowledge, any of its
officers, directors or affiliates has taken, and at the Closing Date and at any
later Option Closing Date, neither the Company nor, to its knowledge, any of its
officers, directors or affiliates will have taken, directly or indirectly, any
action which has constituted, or might reasonably be expected to constitute, the
stabilization or manipulation of the price of sale or resale of the Securities.

                aa.     The Company and the Subsidiary maintain insurance of the
types and in amounts adequate for its and its Subsidiary's business and
consistent with insurance coverage maintained by similar companies in similar
business, including but not limited to, insurance covering clinical trial
liability, product liability and real and personal property owned or leased
against theft, damage, destruction, acts of vandalism and all other



                                       18
<PAGE>   19

risks customarily insured against, all of which insurance is in full force and
effect.

                ab.     The Company and the Subsidiary have filed all material
tax returns required to be filed, which returns are true and correct in all
material respects, and neither the Company nor the Subsidiary is in default in
the payment of any taxes, including penalties and interest, assessments, fees
and other charges, shown thereon due or otherwise assessed, other than those
being contested in good faith and for which adequate reserves have been provided
or those currently payable without interest which were payable pursuant to said
returns or any assessments with respect thereto.

                ac.     Except as described in the Prospectus, to the best of
the Company's knowledge, there are no rulemaking or similar proceedings before
The United States Food and Drug Administration or comparable Federal, state,
local or foreign government bodies which involve or affect the Company or the
Subsidiary, which, if the subject of an action unfavorable to the Company or the
Subsidiary, could involve a prospective material adverse change in or effect on
the condition, financial or otherwise, or in the earnings, business affairs or
business prospects of the Company and the Subsidiary considered as one
enterprise.

                ad.     The Company has not received any communication (whether
written or oral) relating to the termination or threatened termination or
modification or threatened modification of any material, consulting, licensing,
marketing, research and development, cooperative or any similar agreement,
including, without limitation, the collaborative research and license agreements
listed under the section of the Prospectus entitled, "Business-Collaborative
Relationships and Licenses." Each such collaborative and licensing agreement is
in effect substantially as described in such section of the Prospectus.

                ae.     To the knowledge of the Company, if any full-time
employee identified in the Prospectus has entered into any non-competition,
non-disclosure, confidentiality or other similar agreement with any party other
than the Company or the Subsidiary, such employee is neither in violation
thereof nor is expected to be in violation thereof as a result of the business
conducted or expected to be conducted by the Company or the Subsidiary as
described in the Prospectus or such person's performance of his obligations to
the Company or the Subsidiary; and neither the Company nor the Subsidiary has
received written notice that any consultant or scientific advisor of the Company
or the Subsidiary is in violation of any non-competition, non-disclosure,
confidentiality or similar agreement.

        7.      INDEMNIFICATION AND CONTRIBUTION.

                a.      The Company agrees to indemnify and hold harmless (i)
each Underwriter and (ii) each person, if any, who controls any Underwriter
within the meaning of Section 15 of the 1933 Act (any of the persons referred to
in this clause (ii) being hereinafter referred to as a "controlling person") and
(iii) the respective directors, officers, partners and employees of any of the
Underwriters or any controlling person (any person referred to in clause (i),
(ii) or (iii) may hereinafter be referred to as an "Indemnified Person") to the
fullest extent lawful, from and against any and all losses, claims, damages,
liabilities and expenses whatsoever (including, without limitation, all
reasonable costs of pursuing, investigating and defending any claim, suit or
action or any investigation or proceeding by any governmental agency or body,
commenced or threatened, including the reasonable fees and expenses of counsel
to any Indemnified Person), directly or indirectly, caused by, related to, based
upon or arising out of or in connection with any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement or
any amendment thereto, including the Rule 430A Information and Rule 434
Information, if applicable, 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 or caused by, related to, based upon, arising
out of or in connection with any untrue statement or alleged untrue statement of
a material fact contained in any preliminary prospectus or the Prospectus (or
any amendment or supplement thereto) or any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, except insofar as such losses, claims, damages,
liabilities or expenses arise out of or are based upon any untrue statement or
omission or alleged untrue statement or omission which has been made therein or
omitted therefrom in reliance upon and in conformity with the information
relating to such Underwriter furnished in writing to the Company by or on behalf
of any Underwriter through you expressly for use in connection therewith;
provided, however, that the indemnification contained in this paragraph a. with
respect to any preliminary prospectus shall not inure to the benefit of any
Underwriter (or related Indemnified Person) on account of any such loss, claim,
damage, liability or expense arising from the sale of the Securities by such
Underwriter to any person if a copy of the Prospectus shall not have been
delivered or sent to such person within the time required by the 1933 Act or the
1933 Act Regulations, and the untrue statement or alleged untrue statement or
omission or alleged omission of a material fact contained in



                                       20
<PAGE>   21

such preliminary prospectus was corrected in the Prospectus (or any amendment or
supplement thereto), provided that the Company has delivered the Prospectus to
the several Underwriters in requisite quantity on a timely basis to permit such
delivery or sending.

                b.      If any action, suit or proceeding shall be brought
against any Indemnified Person in respect of which indemnity may be sought
against the Company, such Indemnified Person shall promptly notify the parties
against whom indemnification is being sought (the "indemnifying parties"), and
such indemnifying parties shall assume the defense thereof, including the
employment of counsel and payment of all fees and expenses. Such Indemnified
Person shall have the right to employ separate counsel in any such action, suit
or proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Person
unless (i) the indemnifying parties have agreed in writing to pay such fees and
expenses, (ii) the indemnifying parties have failed to assume the defense and
employ counsel or (iii) the named parties to any such action, suit,
investigation or proceeding (including any impleaded parties) include both such
Indemnified Person and the indemnifying parties and representation of such
Indemnified Person and any indemnifying party by the same counsel would, in the
reasonable judgment of the Indemnified Person, be inappropriate due to actual or
potential differing interests between them (in which case the indemnifying party
shall not have the right to assume the defense of such action, suit or
proceeding on behalf of such Indemnified Person). It is understood, however,
that the indemnifying parties shall, in connection with any one such action,
suit or proceeding or separate but substantially similar or related actions,
suits or proceedings in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
only one separate firm of attorneys (in addition to any local counsel) at any
time for all such Indemnified Persons not having actual or potential differing
interests with you or among themselves, which firm shall be designated in
writing by EVEREN, and that all such fees and expenses shall be reimbursed as
they are incurred. The indemnifying parties shall not be liable for any
settlement of any such action, suit or proceeding effected without their written
consent, which consent shall not be unreasonably withheld, but if settled with
such written consent, or if there be a final judgment for the plaintiff in any
such action, suit or proceeding, the indemnifying parties agree to indemnify and
hold harmless any Indemnified Person, to the extent provided in the preceding
paragraph, from and against any loss, claim, damage, liability or expense by
reason of such settlement or judgment.



                                       21
<PAGE>   22

                c.      Each Underwriter agrees, severally and not jointly, to
indemnify and hold harmless the Company, its directors, its officers who sign
the Registration Statement, any person who controls the Company within the
meaning of Section 15 of the 1933 Act, to the same extent as the foregoing
indemnity from the Company to each Indemnified Person, but only with respect to
information relating to such Underwriter furnished in writing by or on behalf of
such Underwriter through EVEREN expressly for use in the Registration Statement,
the Prospectus or any preliminary prospectus, or any amendment or supplement
thereto. If any action, suit, investigation or proceeding shall be brought
against the Company, any of its directors, any such officer or any such
controlling person based on the Registration Statement, the Prospectus or any
preliminary prospectus, or any amendment or supplement thereto, and in respect
of which indemnity may be sought against any Underwriter pursuant to this
paragraph (c), such Underwriter shall have the rights and duties given to the
Company by paragraph (b) above, and the Company, its directors, any such officer
and any such controlling person shall have the rights and duties given to the
Indemnified Persons by paragraph (a) above.

                d.      If the indemnification provided for in this Section 7 is
unavailable to, or insufficient to hold harmless, an indemnified party under
paragraphs (a) or (c) hereof in respect of any losses, claims, damages,
liabilities or expenses referred to therein, then each indemnifying party, in
lieu of indemnifying such indemnified party, shall contribute to the amount paid
or payable by such indemnified party as a result of such losses, claims,
damages, liabilities or expenses (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company on the one hand and the
Underwriters on the other hand from the offering of the Securities or (ii) if
the allocation provided by clause (i) above is not permitted by applicable law
or judicial determination, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company on the one hand and the Underwriters on the other hand, as
well as any other relevant equitable considerations. The relative benefits
received by the Company on the one hand and the Underwriters on the other hand
shall be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectus or, if Rule
434 is used, the corresponding location on the Term Sheet. The relative fault of
the Company on the one hand and the Underwriters on the other hand shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact



                                       22

or the omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or by the Underwriters on
the other hand and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The indemnity and contribution obligations of the Company set forth herein shall
be in addition to any liability or obligation the Company may otherwise have to
any Indemnified Person.

                e.      The Company and the Underwriters agree that it would not
be just and equitable if contribution pursuant to this Section 7 were determined
by a pro rata allocation (even if the Underwriters were treated as one entity
for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages, liabilities and expenses referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating any claim or defending any such action,
suit or proceeding. Notwithstanding the provisions of this Section 7, no
Underwriter (or any of its related Indemnified Persons) shall be required to
contribute (whether pursuant to subsection (a) or (c) or otherwise) any amount
in excess of the underwriting discount applicable to the Securities underwritten
by such Underwriter. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution
from any person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations to contribute pursuant to this Section 7 are several
in proportion to the respective numbers of Securities set forth opposite their
names in Schedule I hereto (or such numbers of Securities increased as set forth
in Section 10 hereof) and not joint.

                f.      No indemnifying party shall, without the prior written
consent of the Indemnified Person, effect any settlement of any pending or
threatened action, suit or proceeding in respect of which any Indemnified Person
is or could have been a party and indemnity could have been sought hereunder by
such Indemnified Person, unless such settlement includes an unconditional
release of such Indemnified Person from all liability on claims that are the
subject matter of such action, suit or proceeding.

                g.      Any losses, claims, damages, liabilities or expenses for
which an indemnified party is entitled to indemnification or contribution under
this Section 7 shall be paid by the indemnifying party to the indemnified party
as such losses,



                                       23
<PAGE>   24

claims, damages, liabilities or expenses are incurred. The indemnity and
contribution agreements contained in this Section 7 and the representations and
warranties of the Company set forth in this Agreement shall remain operative and
in full force and effect, regardless of (i) any investigation made by or on
behalf of any Indemnified Person, the Company, its directors or officers or any
person controlling the Company, (ii) acceptance of any Securities and payment
therefor hereunder and (iii) any termination of this Agreement.

        8.      CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The several obligations
of the Underwriters to purchase the Initial Securities hereunder are subject to
the following conditions:

                a.      The Registration Statement, including any Rule 462(b)
Registration Statement, shall have become effective on the date hereof; no stop
order suspending the effectiveness of the Registration Statement shall have been
issued under the 1933 Act or proceedings therefor initiated or threatened by the
Commission. If the Company has elected to rely upon Rule 430A, Rule 430A
Information previously omitted from the effective Registration Statement
pursuant to Rule 430A shall have been transmitted to the Commission for filing
pursuant to Rule 424(b) within the prescribed time period and the Company shall
have provided evidence satisfactory to the Underwriters of such timely filing,
or a post-effective amendment providing such information shall have been
promptly filed and declared effective in accordance with the requirements of
Rule 430A. If the Company has elected to rely upon Rule 434, a Term Sheet shall
have been transmitted to the Commission for filing pursuant to Rule 424(b)
within the prescribed time period.

                b.      The Underwriters shall have received:

                        (i)     The favorable opinion, dated as of the Closing
    Date, of Parsons Behle & Latimer, counsel for the Company, in form and
    substance satisfactory to counsel for the Underwriters, to the effect that:

                A.      The Company has been duly incorporated and is validly
        existing as a corporation in good standing under the laws of the State
        of Utah.

                B.      The Company has corporate power and authority to own,
        lease and operate its properties and to conduct its business as

        Agreement and the Representatives' Warrant Agreement.

                C.      To the best of their knowledge and information, the
        Company is duly qualified as a foreign corporation to transact business
        and is in good standing in each jurisdiction in which such qualification
        is required.

                D.      The authorized, issued and outstanding capital stock of
        the Company is as set forth in the Prospectus under "Capitalization"
        (except for subsequent issuances, if any, pursuant to reservations,
        agreements, employee benefit plans or the exercise of convertible
        securities referred to in the Prospectus), and the shares of issued and
        outstanding capital stock of the Company, including the Common Shares,
        have been duly authorized and validly issued and are fully paid and
        non-assessable and, to their knowledge and information, have not been
        issued in violation of or are not otherwise subject to any preemptive
        rights or other similar rights.

                E.      The Securities have been duly authorized for issuance
        and sale to the Underwriters pursuant to this Agreement and, when issued
        and delivered by the Company pursuant to this Agreement against payment
        of the consideration set forth herein, will be validly issued and fully
        paid and non-assessable; and the issuance of the Securities is not
        subject to preemptive or other similar rights.

                F.      The Subsidiary has been duly incorporated and is validly
        existing as a corporation in good standing under the laws of the
        jurisdiction of its incorporation, has corporate power and authority to

        capital stock of the Subsidiary has been duly authorized and validly
        issued, is fully paid and non-assessable and, to the best of their

                                       25
<PAGE>   26

        free and clear of any security interest, mortgage, pledge, lien,
        encumbrance, claim or equity, except as described in the Prospectus.

                G.      To the best of their knowledge and information, except
        as described in the Prospectus, there are no outstanding options,
        warrants or other rights granted to or by the Company to purchase Common
        Shares or other securities of the Company and there are no commitments,
        plans or arrangements to issue any Common Shares or other securities.

                H.      Each of this Agreement and the Representatives' Warrant
        Agreement has been duly authorized, executed and delivered by the
        Company.

                I.      At the time the Registration Statement became effective
        and at the Closing Date, the Registration Statement (other than the
        financial statements and supporting schedules included therein, as to
        which no opinion need be rendered) complied as to form in all material
        respects with the requirements of the 1933 Act and the 1933 Act
        Regulations.

                J.      The form of certificate used to evidence each of the
        Securities is in due and proper form and complies with all applicable
        statutory requirements.

                K.      To the best of their knowledge and information, there
        are no legal or governmental proceedings pending or threatened which are
        required to be disclosed in the Registration Statement other than those
        disclosed therein, and all pending legal or governmental proceedings to
        which the Company or the Subsidiary is a party or to which any of their
        property is subject which are not described in the Registration
        Statement, including ordinary routine litigation incidental to the
        business, are, considered in the aggregate, not material.

                L.      The information in the Prospectus under
        "Business--Government Regulation," "Description of Capital Shares,"
        Business--Collaborative Relationships," "Management--Employee Benefit
        Plans," "Certain Transactions," and "Shares



                                       26

        Eligible for Future Sale" and Item 15 of Part II of the Registration
        Statement to the extent that it constitutes matters of law, summaries of
        legal matters, documents or proceedings, or legal conclusions, has been
        reviewed by them and is correct in all material respects and fairly and
        correctly presents the information called for with respect thereto.

                M.      To the best of their knowledge and information, there
        are no contracts, indentures, mortgages, loan agreements, deeds, trusts,
        notes, leases, subleases, voting trusts, voting agreements or other
        instruments or agreements required to be described or referred to in the
        Registration Statement or to be filed as exhibits thereto other than
        those described or referred to therein or filed as exhibits thereto, the
        descriptions thereof or references thereto are correct; and to the best
        of their knowledge and information, no default exists in the due
        performance or observance of any material obligation, agreement,
        covenant or condition contained in any material contract, indenture,
        mortgage, loan agreement, deed, trust, note, lease, sublease, voting
        trust, voting agreement or other instrument or agreement of the Company
        or the Subsidiary.

                N.      No authorization, approval, consent or order of any
        court or governmental authority or agency is required in connection with
        the offering, issuance or sale of the Securities to the Underwriters,
        except such as may be required under the 1933 Act or the 1933 Act
        Regulations or state securities or Blue Sky laws or such as may be
        required by the NASD; and the execution, delivery and performance of
        this Agreement and the Reprsentatives' Warrant Agreement and the
        consummation of the transactions contemplated herein and therein and the
        compliance by the Company with its obligations hereunder and thereunder
        will not conflict with or constitute a breach of, or default under, or
        result in the creation or imposition of any lien, charge or encumbrance
        upon any property or assets of the Company or the Subsidiary pursuant
        to, any contract, indenture, mortgage, loan agreement, note, deed,
        trust, lease, sublease, voting trust,



                                       27

        voting agreement or other instrument or agreement to which the Company
        or the Subsidiary is a party or by which it or any of them may be bound,
        or to which any of the property or assets of the Company or the
        Subsidiary is subject, nor will such action result in any violation of
        the provisions of the charter or bylaws of the Company or the
        Subsidiary, or any applicable statute, law, rule, regulation, ordinance,
        code, decision, directive or order.

                O.      Except as described in the Prospectus, to the best of
        their knowledge and information, there are no persons with registration
        or other similar rights to have any securities registered pursuant to
        the Registration Statement or otherwise registered by the Company under
        the 1933 Act.

                P.      The Company is not an "investment company" or a company
        "controlled" by an "investment company" within the meaning of the
        Investment Company Act of 1940, as amended.

                Q.      All sales of the Company's capital stock during the
        three years immediately prior to the date hereof were at all relevant
        times duly registered or exempt from the registration requirements of
        the 1933 Act.

                R.      To the best of their knowledge and information, the
        Company and the Subsidiary are in compliance with, and conduct their
        respective businesses in conformity with, all applicable laws and
        regulations relating to the operation of its business as described in
        the Registration Statement, except to the extent that any failure so to
        comply or conform would not have a material adverse effect upon the
        business or condition, financial or otherwise, of the Company and the
        Subsidiary considered as one enterprise.

                S.      The Representatives' Warrants are exercisable for Common
        Shares in accordance with the terms of the Representatives' Warrant
        Agreement and at the prices therein provided; the Common Shares issuable
        upon the exercise of the Representatives' Warrants have been duly
        authorized and reserved for issuance upon such exercise and such shares,
        when issued upon such exercise in



                                       28
<PAGE>   29

        accordance with the terms of the Representatives' Warrant Agreement,
        will be duly authorized, validly issued, fully paid and nonassessable;
        and there are no preemptive or other rights to subscribe for or to
        purchase, nor any restriction upon the voting or transfer of, any Common
        Shares issuable upon exercise of the Representatives' Warrants pursuant
        to the Company's charter or by-laws or any agreement or other
        outstanding instrument.

                T.      The Registration Statement has become effective under
        the 1933 Act; any required filing of the Prospectus, and any supplements
        thereto or the Term Sheet, pursuant to Rule 424(b) and if applicable,
        Rule 434, has been made in the manner and within the time period
        required; and to their best knowledge and information, no stop order
        suspending the effectiveness of the Registration Statement or any part
        thereof has been issued and no proceedings therefor have been instituted
        or are pending or contemplated under the 1933 Act.

                        (ii)    The favorable opinion, dated as of the Closing
Date, of Workman, Nydegger & Seeley, patent counsel for the Company, in form and
substance satisfactory to counsel for the Underwriters, to the effect that:

                A.      The information in the Prospectus under "Risk
        Factors--Patents and Proprietary Rights" "Business--Collaborative
        Relationships and Licenses" and "Business-Patents and Proprietary
        Rights" to the extent that it constitutes matters of law, summaries of
        legal matters, documents or proceedings, or legal conclusions, has been
        reviewed by them and is correct in all material respects and fairly and
        correctly presents the information called for with respect thereto.

                B.      To the best of their knowledge, there are no pending or
        threatened legal or governmental proceedings, nor allegations on the
        part of any person of infringement, relating to patent rights, trade
        secrets, trademarks, service marks, copyrights or other proprietary
        information or know-how of the Company and, to the best of their
        knowledge, no such proceedings are threatened or contemplated.



                                       29
<PAGE>   30

                C.      To the best of their knowledge, the Company is not
        infringing or otherwise violating any patents, trade secrets,
        trademarks, service marks, copyrights or other proprietary information
        or know-how of any persons, and no person is infringing or otherwise
        violating any of the Company's patents, trade secrets, trademarks,
        service marks, copyrights or other proprietary information or know-how
        of the Company in a way in which could materially affect the use thereof
        by the Company.

                D.      To the best of their knowledge, the Company owns or
        possesses sufficient licenses or other rights to use all patents, trade
        secrets, trademarks, service marks or other proprietary information or
        know-how necessary to conduct the business now being or proposed to be
        conducted by the Company as described in the Prospectus.

                E.      The Company is listed in the records of the United
        States Patent and Trademark Office ("PTO") as the sole assignee of
        record of each of the patents listed on Schedule I hereto (herein called
        the "Patents") and each of the applications listed on Schedule II hereto
        (herein called the "Applications"). To the best of their knowledge,
        there are no asserted or unasserted claims of any persons relating to
        the scope or ownership of the Patents or the Applications, there are no
        liens which have been filed against any of the Patents or the
        Applications, there are no material defects of form in the preparation
        or filing of the Applications, the Applications are being diligently
        prosecuted, and none of the Applications has been finally rejected or
        abandoned.

                F.      The Company is listed in the records of the appropriate
        foreign patent offices as the sole assignee of record of each of the
        foreign patents listed on Schedule III hereto (herein called the
        "Foreign Patents") and each of the foreign applications listed on
        Schedule IV hereto (herein called the "Foreign Applications"). To the
        best of their knowledge, there are no asserted or unasserted claims of
        any persons relating to the scope or ownership of the Foreign Patents or
        the Foreign Applications, there are no liens which have



                                       30
<PAGE>   31

        been filed against any of the Foreign Patents or the Foreign
        Applications, there are no material defects of form in the preparation
        or filing of the Foreign Applications, the Foreign Applications are
        being diligently prosecuted, and none of the Foreign Applications has
        been finally rejected or abandoned.

                G.      Nothing has come to their attention that leads them to
        believe that the Applications and the Foreign Applications will not
        eventuate in issued patents, or that any patents issued in respect of
        any such Applications or Foreign Applications will not be valid or will
        not afford the Company reasonable patent protection relative to the
        subject matter thereof.

                H.      The Company is the non-exclusive licensee of the United
        States and foreign patents and patent applications listed on Schedule V
        and is the exclusive licensee of the United States and foreign patents
        and patent applications listed on Schedule VI. All such licenses are
        duly executed, validly binding and enforceable in accordance with their
        terms and, to the best of their knowledge, the Company is not in default
        (declared or undeclared) of any material provision of any such licenses.

                I.      To the best of their knowledge, all pertinent prior art
        references known to the Company or its counsel during the prosecution of
        the Patents and the Applications were disclosed to the PTO and, to the
        best of their knowledge, neither such counsel nor the Company made any
        misrepresentation to, or concealed any material fact from, the PTO
        during such prosecution.

                J.      To the best of their knowledge, the Company takes
        security measures adequate to assert trade secret protection in its
        non-patented technology.

                K.      The agreements executed by the Company's employees,
        consultants and other advisors respecting trade secrets,
        confidentiality, or intellectual property rights are valid, binding and
        enforceable in accordance with their express terms.



                                       31
<PAGE>   32

                L.      Nothing has come to their attention that leads them to
        believe that, with respect to licenses, patents, trade secrets,
        copyrights or other proprietary information or know-how owned or used by
        the Company which are the subject of the foregoing opinions, the
        Registration Statement, at the time it became effective, contained an
        untrue statement of a material fact or omitted to state a material fact
        required to be stated therein or necessary to make the statements
        therein not misleading or that the Prospectus, as of its date (unless
        the term "Prospectus" refers to a prospectus which has been provided to
        the Underwriters by the Company for use in connection with the offering
        of the Securities which differs from the Prospectus on file at the
        Commission at the time the Registration Statement becomes effective, in
        which case at the time it is first provided to the Underwriters for such
        use) or at the Closing Date or the Option Closing Date, as the case may
        be, included or includes an untrue statement of a material fact or
        omitted or omits to state a material fact necessary in order to make the
        statements therein, in the light of the circumstances under which they
        were made, not misleading.

                        (iii)   The favorable opinion, dated as of the Closing
Date, of Hogan & Hartson, regulatory counsel for the Company, in form and
substance satisfactory to counsel for the Underwriters, to the effect that:

                A.      The information in the Prospectus under "Risk
        Factors--Uncertainties Related to Product Development; Clinical Trails,"
        "Risk Factors--Government Regulation," "Risk Factors--Health Care
        Reimbursement," and "Business--Government Regulation," (such sections
        collectively referred to as the "Regulatory Sections") insofar as such
        statements purport to summarize applicable provisions of the Federal
        Food, Drug, and Cosmetic Act and the regulations promulgated thereunder,
        are accurate summaries in all material respects of the provisions
        purported to be summarized under such captions in the Prospectus.

                B.      No facts have come to their attention which cause them
to believe that the statements in



                                       32
<PAGE>   33

        the Regulatory Sections insofar as such statements relate to FDA
        regulatory matters at the time the Registration Statement became
        effective, contain an untrue statement of a material fact or omitted to
        state a material fact required to be stated therein or necessary to make
        the statements therein not misleading, or as of the Closing Date
        contains an untrue statement of a material fact or omits to state a
        material fact necessary in order to make the statements therein, in the
        light of the circumstances under which they were made, not misleading.

                        (iv)    The favorable opinion, dated as of the Closing
Date, of Skadden, Arps, Slate, Meagher & Flom (Illinois), counsel for the
Underwriters with respect to the issuance and sale of the Securities, the
Registration Statement and the Prospectus and such other related matters as the
Underwriters shall reasonably request.

                        (v)     In giving their opinions required by subsections
(b)(i) and (b)(iv), respectively, of this Section 8, Parsons Behle & Latimer and
Skadden, Arps, Slate, Meagher & Flom (Illinois) shall each additionally state
that nothing has come to their attention that leads them to believe that the
Registration Statement (except for financial statements and schedules and other

pursuant to any provisions hereof (otherwise than pursuant to the second
paragraph of Section 10 or pursuant to clauses (ii), (iii), (iv) and (v) of
Section 11 hereof) or if this Agreement shall be terminated by the Underwriters
because of any failure or refusal on the part of the Company to comply, in any
material respect, with the terms or fulfill, in any material respect, any of the
conditions of this Agreement, the Company agrees to reimburse the
Representatives for all reasonable out-of-



                                       37
<PAGE>   38

pocket expenses (including reasonable fees and expenses of counsel for the
Underwriters) incurred by you in connection herewith.

        10.     EFFECTIVE DATE OF AGREEMENT. This Agreement shall become
effective: (i) upon the execution and delivery hereof by or on behalf of the
parties hereto; or (ii) if, at the time this Agreement is executed and
delivered, it is necessary for the Registration Statement or a post-effective
amendment thereto to be declared effective before the offering of the Securities
may commence, when notification of the effectiveness of the Registration
Statement or such post-effective amendment has been released by the Commission.
Until such time as this Agreement shall have become effective, it may be
terminated by the Company, by notifying you, or by you, as Representatives of
the several Underwriters, by notifying the Company.

        If one or more of the Underwriters shall fail on the Closing Date to
purchase the Initial Securities which it or they are obligated to purchase under
this Agreement (the "Defaulted Securities"), the Representatives shall have the
right, within 24 hours thereafter, to make arrangements for one or more of the
non-defaulting Underwriters, or any other underwriters, to purchase all, but not
less than all, of the Defaulted Securities in such amounts as may be agreed upon
and upon the terms herein set forth; if, however, the Representatives shall not
have completed such arrangements within such 24-hour period, then:

                a.      if the number of Defaulted Securities does not exceed
10% of the number of Initial Securities, the non-defaulting Underwriters shall
be obligated to purchase the full amount thereof in the proportions that their
respective underwriting obligations hereunder bear to the underwriting
obligations of all non-defaulting Underwriters, or

                b.      if the number of Defaulted Securities exceeds 10% of the
number of Initial Securities, this Agreement shall terminate without liability
on the part of any non-defaulting Underwriter.

        No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.

        In the event of any such default which does not result in a termination
of this Agreement, either the Representatives or the Company shall have the
right to postpone the Closing Date for a period not exceeding seven days in
order to effect any required changes in the Registration Statement or Prospectus
or in any other



                                       38
<PAGE>   39

documents or arrangements. As used herein, the term "Underwriter" includes any
person substituted for an Underwriter under this Section 10.

                Any notice under this Section 10 may be given by telegram,
telecopy or telephone but shall be subsequently confirmed by letter.

        11.     TERMINATION OF AGREEMENT. a. The Underwriters may terminate this
Agreement, by notice to the Company, at any time at or prior to the Closing Date
or Option Closing Date, as the case may be, (i) if there has been, since the
date of this Agreement or since the respective dates as of which information is
given in the Registration Statement, any material adverse change or any
development involving a prospective material adverse change in or affecting the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of the Company and the Subsidiary considered as one
enterprise, whether or not arising in the ordinary course of business, (ii) if
there has occurred any change in the financial markets in the United States or
elsewhere or any outbreak of hostilities or escalation thereof or other calamity
or crisis the effect of which is such as to make it, in your judgement,
impracticable or inadvisable to market the Securities or to enforce contracts
for the sale of the Securities, (iii) if trading in the Common Shares has been
suspended by the Commission, or if trading generally on the American Stock
Exchange, the New York Stock Exchange or in the over-the-counter markets has
been suspended, or minimum or maximum prices for trading have been fixed, or
maximum ranges for prices for securities have been required, by such exchange or
markets or by order of the Commission or any other governmental authority, or if
a banking moratorium has been declared by either Federal, New York or Illinois
authorities, (iv) the enactment, publication, decree or other promulgation of
any Federal or state statute, regulation, rule or order of any court or other
governmental authority which in your judgement materially and adversely affects
or may materially or adversely affect the business or operations of the Company
and the Subsidiary or (v) the taking of any action by any Federal, state or
local government or agency in respect of its monetary or fiscal affairs which in
your judgement has a material adverse effect on the securities markets in the
United States, and would in your judgement make it impracticable or inadvisable
to market the Securities or to enforce any contract for the sale thereof. Notice
of such termination may be given by telegram, telecopy or telephone and shall be
subsequently confirmed by letter.

                b.      If this Agreement is terminated pursuant to this Section
11, such termination shall be without liability of any



                                       39

party to any other party except as provided in Section 9 and provided further

1997, between IOMED, INC., a Utah corporation (the "Company"), and EVEREN

                              W I T N E S S E T H:

                 WHEREAS, the Company proposes to issue to the Representatives
warrants ("Warrants") to purchase up to an aggregate of 170,000 Common Shares
(as defined in Section 15 hereof);

                 WHEREAS, pursuant to the underwriting agreement (the
"Underwriting Agreement"), dated as of the date hereof, between the
Representatives, as representatives of the several Underwriters (as such term
is defined in the Underwriting Agreement), and the Company, the Representatives
and the other Underwriters have agreed to purchase 1,700,000 common shares of
the Company, at a public offering price of $_____ per share in connection with
the Company's proposed initial public offering (the "Public Offering"); and

                 WHEREAS, the Warrants to be issued pursuant to this Agreement
will be issued on the Closing Date (as such term is defined in the Underwriting
Agreement) by the Company to the Representatives in consideration for, and as
part of the Representatives' compensation in connection with, the performance
of the Representatives  pursuant to the Underwriting Agreement.

                 NOW, THEREFORE, in consideration of the premises, the payment
by the Representatives to the Company of an aggregate of one hundred dollars
($100.00), the agreements herein set forth and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
the parties hereto agree as follows:

                 Section  1.  Grant.  The Representatives are hereby granted
the right to purchase, at any time from ________, 1997 [the first anniversary
of the effective date of the registration statement] until 5:30 p.m., New York
time, on _________, 2002 [the fifth anniversary of the effective date of the
registration statement] (the "Exercise Period"), up to an aggregate of 170,000
Common Shares





<PAGE>   5


(the "Warrant Shares"), subject to the terms and conditions of this Agreement,
at an initial exercise price (subject to adjustment as provided in Section 8
hereof) of (i) $______ [125% of the initial public offering price per share]
per Common Share until __________, 2000 [the third anniversary of the effective
date of the registration statement] or (ii) $_____ [150% of the initial public
offering price per share] per Common Share after __________, 2000 [the third
anniversary of the effective date of the registration statement].

                 Section  2.  Warrant Certificates.  The warrant certificates
(the "Warrant Certificates") delivered and to be delivered pursuant to this
Agreement shall be in the form set forth in Exhibit A, attached hereto and made
a part hereof, with such appropriate insertions, omissions, substitutions and
other variations as are required or permitted by this Agreement.

                 Section  3.  Exercise of Warrant.

                 Section  3.1  Method of Exercise.  The Warrants initially are
exercisable at an aggregate initial exercise price per Common Share set forth
in Section 6 hereof (subject to adjustment as provided in Section 8 hereof)
payable by certified or official bank check in New York Clearing House funds.
Upon surrender of a Warrant Certificate with the annexed Form of Election to
Purchase duly executed, together with payment of the applicable exercise price
for the Common Shares purchased at the Company's principal executive offices in
Utah (presently located at 3385 West 1820 South, Salt Lake City, Utah 84104)
the registered holder of a Warrant Certificate ("Holder" or "Holders") shall be
entitled to receive a certificate or certificates for the Common Shares so
purchased.  Subject to the other provisions of this Agreement, the purchase
rights represented by each Warrant Certificate are exercisable at the option of
the Holder thereof, in whole or in part (but not as to fractional Common Shares
underlying the Warrants).  In the case of the purchase of less than all the
Common Shares purchasable under any Warrant Certificate, the Company shall
cancel said Warrant Certificate upon the surrender thereof and shall execute
and deliver a new Warrant Certificate of like tenor for the balance of the
Common Shares purchasable thereunder.





                                       2
<PAGE>   6

                 Section  3.2  Exercise by Surrender of Warrants.  In addition
to the method of payment set forth in Section 3.1 and in lieu of any cash
payment required thereunder, the Holder(s) of the Warrants shall have the right
at any time and from time to time to exercise the Warrants in whole or in part
by surrendering the Warrant Certificate in the manner specified in Section 3.1
in exchange for the number of Common Shares equal to (x) the number of shares
as to which the Warrants are being exercised multiplied by (y) a fraction, the
numerator of which is the Market Price (as defined in Section 15) of the Common
Shares less the Exercise Price and the denominator of which is such Market
Price.  Solely for the purposes of this paragraph, Market Price shall be
calculated either (i) on the date which the form of election attached hereto is
deemed to have been sent to the Company pursuant to Section 13 hereof ("Notice
Date") or (ii) as the average of the Market Prices for each of the five
consecutive trading days preceding the Notice Date, whichever of (i) or (ii) is
greater.

                 Section  4.  Issuance of Certificates.  Upon the exercise of
the Warrants, the issuance of certificates for Common Shares or other
securities, properties or rights underlying such Warrants, shall be made
forthwith (and in any event within three (3) business days thereafter) without
charge to the Holder thereof including, without limitation, any tax which may
be payable in respect of the issuance thereof, and such certificates shall
(subject to the provisions of Section 1 hereof) be issued in the name of, or in
such names as may be directed by, the Holder thereof; provided, however, that
the Company shall not be required to pay any tax which may be payable in
respect of any transfer involved in the issuance and delivery of any such
certificates in a name other than that of the Holder and the Company shall not
be required to issue or deliver such certificates unless or until the person or
persons requesting the issuance thereof shall have paid to the Company the
amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid.

                 The Warrant Certificates and the certificates representing the
Warrant Shares (and/or other securities, property or rights issuable upon the
exercise of the Warrants) shall be executed on behalf of the Company by the
manual or facsimile signature of the then present





                                       3
<PAGE>   7

Chairman or Vice Chairman of the Board of Directors or President or Vice
President of the Company.  Warrant Certificates shall be dated the date of
execution by the Company upon initial issuance, division, exchange,
substitution or transfer.

                 Section  5.  Transfer of Warrants; Warrant Register.  Any
Warrants issued upon the transfer or exercise in part of this Warrant shall be
numbered and shall be registered in a warrant register as they are issued.  The
Company shall be entitled to treat the registered holder of any Warrant on the
Warrant Register as the owner in fact thereof for all purposes and shall not be
bound to recognize any equitable or other claim to or interest in such Warrant
on the part of any other person, and shall not be liable for any registration
or transfer of such Warrants which are registered or to be registered in the
name of a fiduciary or the nominee of a fiduciary.  Such Warrants shall be
transferable only on the books of the Company upon delivery thereof duly
endorsed by the Holder or by his duly authorized attorney or representative, or
accompanied by proper evidence of succession, assignment, or authority to
transfer.  In all cases of transfer by an attorney, executor, administrator,
guardian, or other legal representative, duly authenticated evidence of his or
its authority shall be produced.  Upon any registration of transfer, the
Company shall deliver a new Warrant or Warrants to the person entitled thereto.
The Warrants may be exchanged, at the option of the Holder thereof, for another
Warrant, or other Warrants of different denominations, of like tenor, and
representing in the aggregate the right to purchase a like number of Warrant
Shares upon surrender to the Company or its duly authorized agent.
Notwithstanding the foregoing, the Company shall have no obligation to cause
Warrants to be transferred on its books to any person if, in the written
opinion of counsel to the Company, such transfer does not comply with the
provisions of the Securities Act of 1933, as amended (the "Act"), and the rules
and regulations thereunder.

                 Section  6.  Exercise Price.

                 Section  6.1  Initial and Adjusted Exercise Price.  Except as
otherwise provided in Section 8 hereof, the initial exercise price of each
Warrant shall be (i) $[____] [125% of the initial public offering price]





                                       4
<PAGE>   8

per Common Share until __________, 2000 [the third anniversary of the effective
date] or (ii) $[_____] after __________, 2000 [the third anniversary of the
effective date.]  The adjusted exercise price shall be the exercise price which
shall result from time to time from any and all adjustments of the initial
exercise price in accordance with the provisions of Section 8 hereof.

                 Section  6.2  Exercise Price.  The term "Exercise Price" as
used herein shall mean the initial exercise price or the adjusted exercise
price, depending upon the context.

                 Section  7.  Registration Rights.

                 Section  7.1  Piggyback Registration.  If, at any time
commencing after the date hereof and expiring seven (7) years thereafter, the
Company proposes to register any of its securities under the Act (other than
pursuant to Form S-4 or Form S-8 or a successor form), either for its own
account or for the account of others, it will give written notice by delivery
in person, registered or certified mail (postage prepaid, return receipt
requested), telex, telecopier or overnight air courier guaranteeing next day
delivery, at least thirty (30) days prior to the filing of each such
registration statement, to the Representatives and to all other Holders of the
Warrants and/or the Warrant Shares of its intention to do so.  If any of the
Holders of the Warrants and/or Warrant Shares notify the Company within twenty
(20) days after receipt of any such notice of its or their desire to include
any Registrable Securities (as defined in Section 15) in such proposed
registration statement, the Company shall afford each such Holder the
opportunity to have any such Registrable Securities registered under such
registration statement.

                 Notwithstanding the foregoing, if, in the case of an
underwritten offering, the managing underwriter of such offering shall advise
the Company in writing that, in its opinion, the distribution of the
Registrable Securities requested to be included in the registration
concurrently with the securities being registered would adversely affect the
market price of such securities, then the offering and sale of such Registrable
Securities shall be delayed for such period, not to exceed ninety (90) days, as
such managing underwriter shall reasonably request.  In the event of a delay as
provided in the





                                       5
<PAGE>   9

preceding sentence, the Company shall, with respect to any Registrable
Securities not included in such offering, file such supplements and
post-effective amendments, and take any such other steps as may be necessary,
to permit the proposed offering and sale of such Registrable Securities for a
period of 270 days immediately following the end of such period of delay.

                 Notwithstanding the provisions of this Section 7.1, the
Company shall have the right at any time after it shall have given written
notice pursuant to this Section 7.1 (irrespective of whether a written request
for inclusion of any such Registrable Securities shall have been made) to elect
not to file any such proposed registration statement, or to withdraw the same
after the filing but prior to the effective date thereof.

                 Section  7.2  Demand Registration.

                          (a)  At any time commencing after the date hereof and
expiring five (5) years thereafter, EVEREN Securities, Inc.  ("EVEREN") or
holders of fifty percent (50%) or more of the Registrable Securities issued or
issuable upon exercise of the Warrants issued to EVEREN (collectively, the
"Initiating Holders") shall have the right (which right is in addition to the
registration rights under Section 7.1 hereof), exercisable by written notice to
the Company, to have the Company prepare and file with the Securities and
Exchange Commission (the "Commission"), on one occasion, a registration
statement and such other documents, including a prospectus, as may be necessary
in the opinion of both counsel for the Company and counsel for EVEREN or such
holders, in order to comply with the provisions of the Act, so as to permit a
public offering and sale of their respective Registrable Securities for nine
(9) consecutive months by such holders and any other holders of Registrable
Securities who notify the Company within twenty (20) days after receiving
notice from the Company of such request.  Notwithstanding the provisions of
this Section 7.2(a), the Company shall not be obligated to register any
Registrable Securities pursuant to this Section 7.2(a) if the number of Warrant
Shares requested to be registered pursuant to this Section 7.2(a) does not
exceed 10,000 Warrant Shares.





                                       6
<PAGE>   10

                          (b)  The Company covenants and agrees to give written
notice of any registration request under this Section 7.2 by any holder or
holders to all other registered Holders of Registrable Securities within five
(5) days from the date of the receipt of any such registration request.

                          (c)  In addition to the registration rights under
Section 7.1 and subsection (a) of this Section 7.2, at any time commencing
after the date hereof and expiring five (5) years thereafter, EVEREN or the
Initiating Holders shall have the right, exercisable by written notice to the
Company, to have the Company prepare and file with the Commission, on one
occasion, a registration statement and such other documents, including a
prospectus, as may be necessary in the opinion of both the counsel for the
Company and counsel for EVEREN or such holders, in order to comply with the
provisions of the Act so as to permit a public offering and sale of their
respective Registrable Securities for twelve (12) consecutive months by such
holders and any other holders of Registrable Securities who notify the Company
within twenty (20) days after receiving notice from the Company of such
request; provided, however, that the provisions of Section 7.3(b) hereof shall
not apply to any such registration request and registration and all costs
incident thereto shall be at the expense of the holder or holders making such
request.

                          (d)  No right of the holders under this Section 7.2
shall be deemed to have been exercised if with respect to such right:

                          (A)  the requisite notice given by holders pursuant
         to this Section 7.2 is withdrawn prior to the date of filing of a
         registration statement or if a registration statement filed by the
         Company under the Act pursuant to this Section 7.2 is withdrawn prior
         to its effective date, in either case, by written notice to the Company
         from EVEREN or the Initiating Holders to be included or which are
         included in such registration statement stating that such holders have
         elected not to proceed with the offering contemplated by such
         registration statement because (i) a development in the Company's
         affairs has occurred or has be-





                                       7
<PAGE>   11

         come known to such holders subsequent to the date of the notice by the
         holders to the Company requesting registration of the Registrable
         Securities or the filing of such registration statement which, in the
         judgment of such holders or the managing underwriter of the proposed
         public offering, materially and adversely affects the market price of
         such Registrable Securities or the distribution of such Registrable
         Securities or (ii) a registration statement filed by the Company
         pursuant to this Section 7.2, in the reasonable opinion of counsel for
         such holders or the managing underwriter of the proposed public
         offering, contains an untrue statement of a material fact or omits to
         state a material fact required to be stated therein or necessary to
         make the statements therein not misleading in light of the
         circumstances under which made (other than any such statement or
         omission relating to such Holders and based on information supplied or
         failed to be supplied by such Holders) and the Company has not,
         promptly after written notice thereof, corrected such statement or
         omission in an amendment filed to such registration statement pursuant
         to Section 7.3(p); or

                          (B) a registration statement pursuant to this Section
         7.2 shall have become effective under the Act and (i) the underwriters
         shall not purchase any Registrable Securities because of a failure of
         a condition contained in the underwriting agreement (other than a
         condition to be performed by or within the control of the holders)
         relating to the offering covered by such registration statement or
         (ii) less than eighty-five percent (85%) of the Registrable Securities
         included therein shall have been sold as a result of any stop order,
         injunction or other order or requirement of the Commission or other
         governmental agency or court, unless such stop order, injunction or
         other order or requirement resulted primarily from an action or omis-
         sion on the part of any holder.

                 Section  7.3  Covenants of the Company with Respect to
Registration.  In connection with any registration under Section 7.1 or 7.2
hereof, the Company covenants and agrees as follows:

                          (a)  The Company shall use its best efforts to file a
registration statement on appropriate form within forty-five (45) days of
receipt of any demand therefor, shall use its best efforts to have any
registration statements declared effective at the earliest possible time, and
shall furnish each Holder desiring to sell Registrable Securities such number
of prospectuses as shall reasonably be requested.

                          (b)  The Company shall pay all costs (other than
underwriting or selling commissions), fees and expenses in connection with all
registration statements filed pursuant to Sections 7.1 and 7.2(a) hereof
including, without limitation, the Company's legal and accounting fees,
printing expenses, blue sky fees and expenses and the fees and expenses of one
counsel for all of the holders.  The holder(s) will pay all costs, fees and
expenses in connection with any registration statement filed pursuant to
Section 7.2(c).  If the Company shall fail to comply with the provisions of
Section 7.3(a), the Company shall, in addition to any other equitable or other
relief available to the holder(s), extend the Exercise Period by such number of
days as shall equal the delay caused by the Company's failure, and be liable
for any or all damages as the holder(s) may be entitled to as a matter of law.

                          (c)  The Company will use its best efforts, in
cooperation with counsel to the underwriters, in qualifying or registering the
Registrable Securities included in a registration statement for offering and
sale under the securities or blue sky laws of such states as the holder(s)
shall designate and to keep such qualifications or registrations in effect for
so long as the registration statement is in effect; provided that the Company
shall not be obligated to qualify to do business in any such jurisdiction or to
file any general consent to service of process in any jurisdiction in any
action other than one arising out of the offering or the sale of the
Registrable Securities.

<PAGE>   13
                          (d)  The Company shall indemnify each holder of
Registrable Securities to be sold pursuant to any registration statement, each
director and officer of such person and each person, if any, who controls such
holder within the meaning of Section 15 of the Act or Section 20(a) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), against all
loss, claim, damage, expense or liability (including all expenses reasonably
incurred in investigating, preparing or defending against any claim
whatsoever), joint or several, to which any of them may become subject under
the Act, the Exchange Act or otherwise, arising from such registration
statement or any final prospectus, preliminary prospectus or summary prospectus
contained therein or any amendment or supplement thereto; provided that the
Company shall not be liable in any such case to the extent that such loss,
claim, damage, expense or liability, arises out of information furnished to the
Company by any holder through an instrument duly executed by such holder
specifically stating that it is for use in the preparation thereof.

                          (e)  The holder(s) of the Registrable Securities to
be sold pursuant to a registration statement, and their successors and assigns,
shall severally, and not jointly, indemnify the Company, its officers and
directors and each person, if any, who controls the Company within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act, against all
loss, claim, damage, expense or liability (including all expenses reasonably
incurred in investigating, preparing or defending against any claim whatsoever)
to which they may become subject under the Act, the Exchange Act or otherwise,
arising from information furnished by such holder(s) through an instrument duly
executed by such holder for specific inclusion in such registration statement
and any final prospectus, preliminary prospectus or summary prospectus
contained therein or any amendment or supplement thereto.  Notwithstanding the
foregoing, no holder of Registrable Securities shall be liable, or required to
indemnify the Company, in the aggregate, for any amount in excess of the net
proceeds received by such holder from the sale of Registrable Securities to
which such loss, claim, damage, liability or expense relates.

                          (f)  Promptly after receipt by any indemnified person
of a notice of a claim or the beginning of





                                       10
<PAGE>   14

any action in respect of which indemnity is to be sought against an
indemnifying person pursuant to Section 7(d) or 7(e), such indemnified person
shall promptly notify the indemnifying person in writing of such claim or of
the commencement of such action; provided, however, that the failure to provide
such notice shall not release the indemnifying person of its obligations under
Sections 7(d) and 7(e) hereof unless and then only to the extent that, the
indemnifying person has been materially prejudiced by such failure to provide
such notice.  Subject to the provisions hereinafter stated, in case any such
action shall be brought against an indemnified person, the indemnifying person
shall be entitled to participate therein, and, to the extent that it shall
wish, to assume the defense thereof, with counsel reasonably satisfactory to
the indemnified person.  After notice from the indemnifying person to such
indemnified person of the indemnifying person's election to assume the defense
thereof, the indemnifying person shall not be liable to such indemnified person
for any legal expenses subsequently incurred by such indemnified person in
connection with the defense thereof; provided, however, that if there exists or
shall exist a conflict of interest that would make it inappropriate in the
reasonable judgment of the indemnified person for the same counsel to represent
both the indemnified person and such indemnifying person or any affiliate or
associate thereof, the indemnified person shall be entitled to retain its own
counsel at the expense of such indemnifying person; provided, further, that the
indemnifying person shall not be obligated to assume the expenses of more than
one counsel (in addition to local counsel) to represent all indemnified
persons.  No indemnifying party shall, without the consent of the indemnified
party, consent to entry of any judgment or enter into any settlement of any
such action 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.  No indemnified party shall
consent to entry of any judgment or enter into any settlement of any such
action the defense of which has been assumed by an indemnifying party without
the consent of such indemnifying party.

                          (g)  If the indemnification provided for in Section
7(d) or 7(e) is unavailable to or insufficient to hold harmless an indemnified
party under subsection





                                       11
<PAGE>   15

7(d) or 7(e) above in respect of any loss, claim, damage, expense or liability
(or actions or proceedings in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
expenses (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of the Company on the one hand and the holders on
the other in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or expenses (or actions in respect
thereof), as well as any other relevant equitable considerations.  The relative
fault shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by
the Company on the one hand or a holder on the other and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.  The Company and the holders agree that it would
not be just and equitable if contributions pursuant to this subsection (g) were
determined by pro rata allocation (even if the holders were treated as one
entity for such purpose) or by any other method of allocation which does not
take into account the equitable considerations referred to above in this
subsection (g).  The amount paid or payable by an indemnified party as a result
of the losses, claims, damages, liabilities or expenses (or actions in respect
thereof) referred to above in this subsection (g) shall be deemed to include
any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (g), no holder of Registrable
Securities shall be required to contribute in the aggregate any amount in
excess of the net proceeds received by such holder from the sale of the
Registrable Securities to which such loss, claim, damage, liability or expense
relates.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.  The holders
obligations in this subsection (g) to contribute are several in proportion to
their sales of the Registrable Securities to which such loss relates and not
joint.





                                       12
<PAGE>   16
                          (h)  The obligations of the Company and the Holders
of Warrants under Sections 7(d), (e) and (g) shall be in addition to any
liability which the Company and the respective holders may otherwise have.

                          (i)  Nothing contained in this Agreement shall be
construed as requiring a Holder to exercise its Warrants prior to the initial
filing of any registration statement or the effectiveness thereof.

                          (j)  The Company shall not permit the inclusion of
any securities other than the Registrable Securities to be included in any
registration statement filed pursuant to Section 7.2 hereof, or file any
registration statement subsequent to the receipt of any notice pursuant to
Section 7.2 hereof and until ninety (90) days after the effectiveness of a
registration statement filed pursuant to Section 7.2 hereof; provided, however,
that in the event of an underwritten public offering, the Company shall have
the right to permit the inclusion of such other securities if the managing
underwriter of such offering advises the Company or the holders in writing
that, in its opinion, the inclusion of such securities other than the
Registrable Securities in such registration statement will not adversely affect
the distribution or the offering price of such Registrable Securities.

                          (k)  In connection with any registration statement
filed pursuant to Section 7.2 hereof, the Company shall furnish to each holder
participating in any underwritten offering and to each underwriter, a signed
counterpart, addressed to such holder or underwriter, of (i) an opinion of
counsel to the Company, dated the effective date of such registration statement
(and, if such registration includes an underwritten public offering, an opinion
dated the date of the closing under the underwriting agreement), and (ii) a
"cold comfort" letter, dated the effective date of such registration statement
(and, if such registration includes an underwritten public offering, a letter
dated the date of the closing under the underwriting agreement), signed by the
independent public accountants who have issued a report on the Company's
financial statements included in such registration statement, in each case
covering substantially the same matters with respect to such registration
statement (and the prospectus included therein) and, in the case of such
accountants' letter, with respect to





                                       13
<PAGE>   17

events subsequent to the date of such financial statements, as are customarily
covered in opinions of issuer's counsel and in accountants' letters delivered
to underwriters in underwritten public offerings of securities.

                          (l)  The Company shall as soon as practicable after
the effective date of the registration statement, and in any event within
fifteen (15) months thereafter, make "generally available to its security
holders" (within the meaning of Rule 158 under the Act) an earnings statement
(which need not be audited) complying with Section 11(a) of the Act and
covering a period of at least twelve (12) consecutive months beginning after
the effective date of the registration statement.

                          (m)  The Company shall deliver promptly to each
holder participating in the offering requesting the correspondence and
memoranda described below, and to the managing underwriters, copies of all
correspondence between the Commission and the Company, its counsel or auditors
and all memoranda relating to discussions with the Commission or its staff with
respect to the registration statement and permit each holder and underwriter to
do such investigation, upon reasonable advance notice, with respect to
information contained in or omitted from the registration statement as it deems
reasonably necessary to comply with applicable securities laws or rules of the
National Association of Securities Dealers, Inc. ("NASD").  Such investigation
shall include access to books, records and properties and opportunities to
discuss the business of the Company with its officers and independent auditors,
all to such reasonable extent and at such reasonable times and as often as any
such Holder or underwriter shall reasonably request.

                          (n)  The Company shall enter into an underwriting
agreement with the managing underwriters selected for such underwriting by
EVEREN or Initiating Holders, which may be any of the Underwriters.  Such
agreement shall be reasonably satisfactory in form and substance to the
Company, each holder and such managing underwriters, and shall contain such
representations, warranties, covenants and indemnities by the Company and such
other terms as are customarily contained in agreements of that type used by the
managing underwriter.  The holders shall be parties to any underwriting
agreement relating to an underwritten sale of their Registrable





                                       14
<PAGE>   18

Securities and may, at their option, require that any or all the
representations, warranties, covenants and indemnities of the Company to or for
the benefit of such underwriters shall also be made to and for the benefit of
such holders.  Such holders shall not be required to make any representations
or warranties to or agreements with the Company or the underwriters except as
they may relate to such holders and their intended methods of distribution.

                          (o)  [This Section Intentionally Left Blank]

                          (p)  The Company shall promptly notify each holder of
Registrable Securities covered by such registration statement, at any time when
a prospectus relating thereto is required to be delivered under the Act, upon
the Company's discovery that, or upon the happening of any event as a result of
which, the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances under which they were
made, and at the request of any such holder promptly prepare and furnish to
such holder and each underwriter, if any, a reasonable number of copies of a
supplement to or an amendment of such prospectus as may be necessary so that,
as thereafter delivered to the purchasers of such securities, such prospectus
shall not include an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances under which they were
made.


                          (q)  The Company shall prepare and file with the
Commission such amendments and supplements to such registration statement and
the prospectus used in connection therewith as may be necessary to keep such
registration statement effective and to comply with the provisions of the Act
with respect to the disposition of all securities covered by such registration
statement until the earlier of such time as all of such securities have been
disposed of in accordance with the intended methods of disposition by the
holder or holders thereof





                                       15
<PAGE>   19
set forth in such registration statement or the expiration of 270 days after
such registration statement becomes effective.

                          (r)  The Company shall furnish to each holder of
Registrable Securities covered by such registration statement and each
underwriter, if any, of the securities being sold by such holder such number of
conformed copies of such registration statement and of each such amendment and
supplement thereto (in each case including all exhibits), such number of copies
of the prospectus contained in such registration statement (including each
preliminary prospectus and any summary prospectus) and any other prospectus
filed under Rule 424 under the Act, in conformity with the requirements of the
Act, and such other documents, as such holder and underwriter, if any, may
reasonably request in order to facilitate the public sale or other disposition
of the Registrable Securities owned by such holder.

                          (s)  The Company shall use its best efforts to cause
all Registrable Securities covered by such registration statement to be
registered with or approved by such other governmental agencies or authorities
as may be necessary to enable the seller or sellers thereof to consummate the
disposition of such Registrable Securities.

                          (t)  The Company shall otherwise use its best efforts
to comply with all applicable rules and regulations of the Commission and will
furnish to each holder of Registrable Securities included in any registration
statement at least three (3) business days prior to the filing thereof a copy
of any amendment or supplement to such registration statement or prospectus and
shall not file any ammendment or supplement thereof to which any such holder
shall have reasonably objected on the grounds that such amendment or supplement
does not comply in all material respects with the requirements of the Act or of
the rules or regulations thereunder.

                 Section  8.  Adjustments to Exercise Price and Number of
Shares.

                 Section  8.1  Adjustment in Number of Shares.  Upon each
adjustment of the Exercise Price pursuant to the provisions of this Section 8,
the number of Warrant





                                       16
<PAGE>   20

Shares issuable upon the exercise of each Warrant shall be adjusted to the
nearest full amount by multiplying a number equal to the Exercise Price in
effect immediately prior to such adjustment by the number of Warrant Shares
issuable upon exercise of the Warrants immediately prior to such adjustment and
dividing the product so obtained by the adjusted Exercise Price.

                 Section  8.2  Issuance of Additional Common Shares.  In case
the Company at any time or from time to time after the date hereof shall issue
or sell Additional Common Shares (including Additional Common Shares deemed to
be issued pursuant to Section 8.4 or 8.5 but excluding any outstanding Options
or Convertible Securities or any outstanding stock options awarded by the board
of directors of the Company pursuant to any of the Company's stock option
plans) without consideration or for a consideration per share less than the
Current Market Price immediately prior to such issue or sale, then, and in each
such case, such Exercise Price shall be reduced, concurrently with such issue
or sale, to a price (calculated to the nearest .001 of a cent) determined by
multiplying such Exercise Price by a fraction:

                          (a)  the numerator of which shall be (i) the number
of Common Shares outstanding immediately prior to such issue or sale plus (ii)
the number of Common Shares which the aggregate consideration received by the
Company for the total number of such Additional Common Shares so issued or sold
would purchase at the Current Market Price, and

                          (b)  the denominator of which shall be the number of
Common Shares outstanding immediately after such issue or sale, provided that,
for the purposes of this Section 8.2 (x) immediately after any Additional
Common Shares are deemed to have been issued pursuant to Section 8.4 or 8.5,
such Additional Shares shall be deemed to be outstanding, and (y) treasury
shares shall not be deemed to be outstanding.

                 Section  8.3  Extraordinary Dividends and Distributions.  In
case the Company at any time or from time to time after the date hereof shall
declare, order, pay or make a dividend or other distribution (including,
without limitation, any distribution of other or additional shares or other
securities or property or Options by way





                                       17
<PAGE>   21

of dividend or spin-off, reclassification, recapitalization or similar
corporate rearrangement) on the Common Shares, other than a dividend payable in
Additional Common Shares, then, and in each such case, the Exercise Price in
effect immediately prior to the close of business on the record date fixed for
the determination of holders of any class of securities entitled to receive
such dividend or distribution shall be reduced, effective as of the close of
business on such record date, to a price (calculated to the nearest .001 of a
cent) determined by multiplying such Exercise Price by a fraction:

                          (a)  the numerator of which shall be the Current
Market Price in effect on such record date or, if the Common Shares trade on an
ex-dividend basis, on the date prior to the commencement of ex-dividend
trading, less the amount of such dividend or distribution (as determined in
good faith by the Board of Directors of the Company) applicable to one Common
Share, and

                          (b)  the denominator of which shall be such Current
Market Price,

provided that, in the event that the amount of such dividend as so determined
is equal to or greater than ten percent (10%) of such Current Market Price or
in the event that such fraction is less than 9/10, in lieu of the foregoing
adjustment, adequate provision shall be made so that the holder of this Warrant
shall receive a pro rata share of such dividend based upon the maximum number
of Common Shares at the time issuable to such holder (determined without regard
to whether the Warrant is exercisable at such time).

                 Section  8.4  Treatment of Options and Convertible Securities.
In case the Company at any time or from time to time after the date hereof
shall issue, sell, grant or assume, or shall fix a record date for the
determination of holders of any class of securities entitled to receive, any
Options or Convertible Securities, then, and in each such case, the maximum
number of Additional Common Shares (as set forth in the instrument relating
thereto, without regard to any provisions contained therein for a subsequent
adjustment of such number) issuable upon the exercise of such Options or, in
the case of Convertible Securities and Options therefor, the conversion or
exchange of such Convertible Securities,





                                       18
<PAGE>   22

shall be deemed to be Additional Common Shares issued as of the time of such
issue, sale, grant or assumption or, in case such a record date shall have been
fixed, as of the close of business on such record date (or, if the Common
Shares trade on an ex-dividend basis, on the date prior to the commencement of
ex-dividend trading), provided that such Additional Common Shares shall not be
deemed to have been issued unless the consideration per share (determined
pursuant to Section 8.6) of such shares would be less than the greater of the
Current Market Price and the Exercise Price in effect on the date of and
immediately prior to such issue, sale, grant or assumption or immediately prior
to the close of business on such record date (or, if the Common Shares trade on
an ex-dividend basis, on the date prior to the commencement of ex-dividend
trading), as the case may be, and provided, further, that in any such case in
which Additional Common Shares are deemed to be issued:

                          (a)  no further adjustment of the Exercise Price
shall be made upon the subsequent issue or sale of Convertible Securities or
Common Shares upon the exercise of such Options or the conversion or exchange
of such Convertible Securities;

                          (b)  if such Options or Convertible Securities by
their terms provide, with the passage of time or otherwise, for any increase in
the consideration payable to the Company, or decrease in the number of
Additional Common Shares issuable, upon the exercise, conversion or exchange
thereof (by change of rate or otherwise), the Exercise Price computed upon the
original issue, sale, grant or assumption thereof (or upon the occurrence of
the record date, or date prior to the commencement of ex-dividend trading, as
the case may be, with respect thereto), and any subsequent adjustments based
thereon, shall, upon any such increase or decrease becoming effective, be
recomputed to reflect such increase or decrease insofar as it affects such
Options, or the rights of conversion or exchange under such Convertible
Securities, which are outstanding at such time;

                          (c)  upon the expiration (or purchase by the Company
and cancellation or retirement) of any such Options which shall not have been
exercised or the expiration of any rights of conversion or exchange under any
such Convertible Securities which (or purchase by the





                                       19
<PAGE>   23
Company and cancellation or retirement of any such Convertible Securities the
rights of conversion or exchange under which) shall not have been exercised,
the Exercise Price computed upon the original issue, sale, grant or assumption
thereof (or upon the occurrence of the record date, or date prior to the
commencement of ex-dividend trading, as the case may be, with respect thereto),
and any subsequent adjustments based thereon, shall, upon such expiration (or
such cancellation or retirement, as the case may be), be recomputed as if:

                                     (i)  in the case of Options for Common
         Shares or Convertible Securities, the only Additional Common Shares
         issued or sold were the Additional Common Shares, if any, actually
         issued or sold upon the exercise of such Options or the conversion or
         exchange of such Convertible Securities and the consideration received
         therefor was the consideration actually received by the Company for
         the issue, sale, grant or assumption of all such Options, whether or
         not exercised, plus the consideration actually received by the Company
         upon such exercise, or for the issue or sale of all such Convertible
         Securities which were actually converted or exchanged, plus the
         additional consideration, if any, actually received by the Company
         upon such conversion or exchange; and

                                     (ii) in the case of Options for
         Convertible Securities, only the Convertible Securities, if any,
         actually issued or sold upon the exercise of such Options were issued
         at the time of the issue, sale, grant or assumption of such Options,
         and the consideration received by the Company for the Additional Common
         Shares deemed to have then been issued was the consideration actually
         received by the Company for the issue, sale, grant or assumption of all
         such Options, whether or not exercised, plus the consideration deemed
         to have been received by the Company (pursuant to Section 8.6) upon the
         issue or sale of such Convertible Securities with respect to which such
         Options were actually exercised;





                                       20
<PAGE>   24
                          (d)  no readjustment pursuant to clause (b) or (c)
above shall have the effect of increasing the Exercise Price by an amount in
excess of the amount of the adjustment thereof originally made in respect of
the issue, sale, grant or assumption of such Options or Convertible Securities;
and

                          (e)  in the case of any such Options which expire by
their terms not more than thirty (30) days after the date of issue, sale, grant
or assumption thereof, no adjustment of the Exercise Price shall be made until
the expiration or exercise of all such Options, whereupon such adjustment shall
be made in the manner provided in clause (c) above.

                 Section  8.5  Treatment of Share Dividends, Share Splits, etc.
In case the Company at any time or from time to time after the date hereof
shall declare or pay any dividend on the Common Shares payable in Common
Shares, or shall effect a subdivision of the outstanding Common Shares into a
greater number of Common Shares (by reclassification or otherwise than by
payment of a dividend in Common Shares), then, and in each such case,
Additional Common Shares shall be deemed to have been issued (a) in the case of
any such dividend, immediately after the close of business on the record date
for the determination of holders of any class of securities entitled to receive
such dividend, or (b) in the case of any such clause, at the close of business
on the day immediately prior to the day upon which such corporate action
becomes effective.

                 Section  8.6  Computation of Consideration.  For the purposes
of this Section 8:

                          (a)  the consideration for the issue or sale of any
Additional Common Shares shall, irrespective of the accounting treatment of
such consideration,

                                   (i)  insofar as it consists of cash, be
         computed at the net amount of cash received by the Company, without
         deducting any expenses paid or incurred by the Company or any
         commissions or compensations paid or concessions or discounts allowed
         to underwriters, dealers or others performing similar services in
         connection with such issue or sale,





                                       21
<PAGE>   25
                                   (ii)  insofar as it consists of property
         (including securities) other than cash, be computed at the fair value
         thereof at the time of such issue or sale, as determined in good faith
         by the Board of Directors of the Company, and

                                   (iii) in case Additional Common Shares are
         issued or sold together with other shares or securities or other
         assets of the Company for a consideration which covers both, be the
         portion of such consideration so received, computed as provided in
         clauses (i) and (ii) above, allocable to such Additional Common
         Shares, all as determined in good faith by the Board of Directors of
         the Company.

                          (b)  Additional Common Shares deemed to have been
issued pursuant to Section 8.4, relating to Options and Convertible Securities,
shall be deemed to have been issued for a consideration per share determined by
dividing:

                                   (i) the total amount, if any, received and
         receivable by the Company as consideration for the issue, sale, grant
         or assumption of the Options or Convertible Securities in question,
         plus the minimum aggregate amount of additional consideration (as set
         forth in the instruments relating thereto, without regard to any
         provision contained therein for a subsequent adjustment of such
         consideration to protect against dilution) payable to the Company upon
         the exercise in full of such Options or the conversion or exchange of
         such Convertible Securities or, in the case of Options for Convertible
         Securities, the exercise of such Options for Convertible Securities
         and the conversion or exchange of such Convertible Securities, in each
         case computing such consideration as provided in the foregoing clause
         (a),

         by

                                   (ii)  the maximum number of Common Shares 
         (as set forth in the instruments





                                       22
<PAGE>   26

         relating thereto, without regard to any provision contained therein
         for a subsequent adjustment of such number to protect against
         dilution) issuable upon the exercise of such Options or the conversion
         or exchange of such Convertible Securities.

                          (c)  Additional Common Shares deemed to have been
issued pursuant to Section 8.5, relating to share dividends, share splits,
etc., shall be deemed to have been issued for no consideration.

                 Section  8.7  Adjustments for Combinations, etc.  In case the
outstanding Common Shares shall be combined or consolidated, by
reclassification or otherwise, into a lesser number of Common Shares, the
Exercise Price in effect immediately prior to such combination or consolidation
shall, concurrently with the effectiveness of such combination or
consolidation, be proportionately increased.

                 Section  8.8  Dilution in Case of Other Securities.  In case
any Other Securities shall be issued or sold or shall become subject to issue
or sale upon the conversion or exchange of any shares (or Other Securities) of
the Company (or any issuer of Other Securities or any other person referred to
in Section 8.9) or to subscription, purchase or other acquisition pursuant to
any Options issued or granted by the Company (or any such other issuer or
person) for a consideration such as to dilute, on a basis consistent with the
standards established in the other provisions of this Section 8, the purchase
rights granted by this Warrant, then, and in each such case, the computations,
adjustments and readjustments provided for in this Section 8 with respect to
the Exercise Price shall be made as nearly as possible in the manner so
provided and applied to determine the amount of Other Securities from time to
time receivable upon the exercise of the Warrants, so as to protect the holders
of the Warrants against the effect of such dilution.

                 Section  8.9  Merger or Consolidation.  In case the Company
after the date hereof (i) shall consolidate with or merge into any other person
and shall not be the continuing or surviving corporation of such consolidation
or merger, or (ii) shall permit any other person to consolidate with or merge
into the Company and the Com-

pany shall be the continuing or surviving person but, in connection with such
consolidation or merger, the Common Shares or Other Securities shall be changed
into or exchanged for stock or Other Securities of any other person or cash or
any other property, or (iii) shall transfer all or substantially all of its
properties or assets to any other person, or (iv) shall effect a capital
reorganization or reclassification of the Common Shares or Other Securities
(other than a capital reorganization or reclassification resulting in the issue
of Additional Common Shares for which adjustment in the Exercise Price is
provided in this Section 8), then, and in the case of each such transaction,
proper provision shall be made so that, upon the basis and the terms and in the
manner provided in this Agreement and the Warrants, the Holders of the
Warrants, upon the exercise thereof at any time after the consummation of such
transaction, shall be entitled to receive (at the aggregate Exercise Price in
effect at the time of such consummation for all Common Shares or Other
Securities issuable upon such exercise immediately prior to such consummation),
in lieu of the Common Shares or Other Securities issuable upon such exercise
prior to such consummation, the highest amount of securities, cash or other
property to which such Holder would actually have been entitled as a
shareholder upon such consummation if such Holder had exercised the rights
represented by the Warrants immediately prior thereto, subject to adjustments
(subsequent to such consummation) as nearly equivalent as possible to the
adjustments provided for in this Section 8; provided that if a purchase, tender
or exchange offer shall have been made to and accepted by the holders of more
than 50% of the outstanding Common Shares, and if a Holder of Warrants so
designates in a notice given to the Company on or before the date immediately
preceding the date of the consummation of such transaction, such Holder of such
Warrants shall be entitled to receive the highest amount of securities, cash or
other property to which such Holder would actually have been entitled as a
shareholder if such Holder of such Warrants had exercised such Warrants prior
to the expiration of such purchase, tender or exchange offer and accepted such
offer, subject to adjustments (from and after the consummation of such
purchase, tender or exchange offer) as nearly equivalent as possible to the
adjustments provided for in this Section 8.

                 Section  8.10  Assumption of Obligations.  Notwithstanding
anything contained in the Warrants to the contrary, the Company will not effect
any of the transactions described in clauses (i) through (iv) of Section 8.4
unless, prior to the consummation thereof, each person (other than the Company)
which may be required to deliver any shares, securities, cash or property upon
the exercise of the Warrants as provided herein shall assume, by written
instrument delivered to, and reasonably satisfactory to, the Holders of the
Warrants, (a) the obligations of the Company under this Agreement and the
Warrants (and if the Company shall survive the consummation of such
transaction, such assumption shall be in addition to, and shall not release the
Company from, any continuing obligations of the Company under this Agreement
and the Warrants) and (b) the obligation to deliver to such Holders such
shares, securities, cash or property as, in accordance with the provisions of
this Section 8, such Holders may be entitled to receive, and such person shall
have similarly delivered to such Holders an opinion of counsel for such person,
which counsel shall be reasonably satisfactory to such Holders, stating that
this Agreement and the Warrants shall thereafter continue in full force and
effect and the terms hereof (including, without limitation, all of the
provisions of this Section 8) shall be applicable to the shares, securities,
cash or property which such person may be required to deliver upon any exercise
of the Warrants or the exercise of any rights pursuant hereto.

                 Section  8.11  Notice of Adjustments.  Whenever the Exercise
Price or the kind of securities or property issuable upon exercise of the
Warrants, or both, shall be adjusted pursuant to this Section 8, the Company
shall make a certificate signed by its President or a Vice President and by its
Chief Financial Officer, Secretary or Assistant Secretary, setting forth, in
reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated (including a
description of the basis on which the Company made any determination
hereunder), and the Exercise Price and the kind of securities or property
issuable upon exercise of the Warrants after giving effect to such adjustment,
and shall cause copies of such certificate to be mailed (by first class mail
postage prepaid) to each Holder promptly after each adjustment.

                 Section  8.12  Preservation of Rights.  The Company will not,
by amendment of its certificate of incorporation or through any consolidation,
merger, reorganization, transfer of assets, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Agreement or the Warrants or the
rights represented thereby, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Holders of the
Warrants against dilution or other impairment.

                 Section  8.13  Other Dilutive Events.  In case any event shall
occur as to which the provisions of Section 8 are not strictly applicable but
the failure to make any adjustment would not fairly protect the purchase rights
represented by this Agreement and the Warrants in accordance with the essential
intent and principles of Section 8, then, in each such case, the Company shall
appoint a firm of independent certified public accountants of recognized
national standing (which may be the regular auditors of the Company), which
shall give their opinion upon the adjustment, if any, on a basis consistent
with the essential intent and principles established in Section 8, necessary to
preserve, without dilution, the purchase rights represented by this Agreement
and the Warrants.  Upon receipt of such opinion, the Company will promptly mail
a copy thereof to the Holder of the Warrants and shall make the adjustments
described therein.

                 Section  8.14  Minimum Adjustment of Warrant Price.  If the
amount of any adjustment of the Warrant Price required pursuant to this Section
8 would be less than 1% of the Warrant Price in effect at the time such
adjustment is otherwise so required to be made, such amount shall be carried
forward and adjustment with respect thereto made at the time of and together
with any subsequent adjustment which, together with such amount and any other
amount or amounts so carried forward, shall aggregate at 1% of such Warrant
Price.

                 Section  9.  Exchange and Replacement of Warrant Certificates.
Each Warrant Certificate is exchangeable without expense, upon the surrender
thereof by the registered Holder at the principal executive office of the
Company, for a new Warrant Certificate of like tenor and





                                       26
<PAGE>   30

date representing in the aggregate the right to purchase the same number of
Warrant Shares in such denominations as shall be designated by the Holder
thereof at the time of such surrender.

                 Upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of any Warrant
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, and reimbursement to the Company of all
reasonable expenses incidental thereto, and upon surrender and cancellation of
the Warrants, if mutilated, the Company will make and deliver a new Warrant
Certificate of like tenor, in lieu thereof.

                 Section  10.  Elimination of Fractional Interests.  The
Company shall not be required to issue certificates representing fractions of
Common Shares upon the exercise of the Warrants, nor shall it be required to
issue scrip or pay cash in lieu of fractional interests, it being the intent of
the parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest whole number of Common Shares or other securities,
properties or rights.

                 Section  11.  Reservation and Listing of Securities.  The
Company shall at all times reserve and keep available out of its authorized
Common Shares, solely for the purpose of issuance upon the exercise of the
Warrants, such number of Common Shares or other securities, properties or
rights as shall be issuable upon the exercise thereof.  The Company covenants
and agrees that, upon exercise of the Warrants and payment of the Exercise
Price therefor, all Common Shares and other securities issuable upon such
exercise shall be duly and validly issued, fully paid, nonassessable and not
subject to the preemptive rights of any shareholder.  As long as the Warrants
shall be outstanding, the Company shall use its best efforts to cause all
Common Shares issuable upon the exercise of the Warrants to be listed on all
securities exchanges and/or included in the automated quotation system of the
Nasdaq National Market System (subject to official notice of issuance) with
respect to which the Common Shares issued to the public in connection herewith
may then be so listed and/or quoted.

funds payable to the order of the Company.

                 No Warrant may be exercised after 5:30 p.m., New York time, on
the Expiration Date, at which time all Warrants evidenced hereby, unless
exercised prior thereto, shall thereafter be void.

                 The Warrants evidenced by this Warrant Certificate are part of
a duly authorized issue of Warrants issued pursuant to the Warrant Agreement,
which Warrant Agreement is hereby incorporated by reference in and made a part
of this instrument and is hereby referred to for a description of the rights,
limitation of rights, obligations, duties and immunities thereunder of the

                 The Warrant Agreement provides that upon the occurrence of
certain events the Exercise Price and the type and/or number of the Company's

In such event, the Company will, at the request of the holder, issue a new
Warrant Certificate evidencing the adjustment in the Exercise Price and the
number and/or type of securities issuable upon the exercise of the Warrants;
provided, however, that the failure of the Company to issue such new Warrant
Certificates shall not in any way change, alter, or otherwise impair the rights
of the holder as set forth in the Warrant Agreement.

                 Upon due presentment for registration of transfer of this
Warrant Certificate at an office or agency of the Company, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee(s) in
exchange for this Warrant Certificate, subject to the limitations provided
herein and in the Warrant Agreement, without any charge except for any tax or
other governmental charge imposed in connection with such transfer.

                 Upon the exercise of less than all of the Warrants evidenced
by this Certificate, the Company shall forthwith issue to the holder hereof a

                 The Company may deem and treat the registered holder(s) hereof
as the absolute owner(s) of this Warrant Certificate (notwithstanding any
notation of ownership or other writing hereon made by anyone), for the purpose
of any exercise hereof, and for all other purposes, and the Company shall not
be affected by any notice to the contrary.

                 All terms used in this Warrant Certificate which are defined
in the Warrant Agreement shall have the meanings assigned to them in the
Warrant Agreement.

     RE:  IOMED, INC.
          REGISTRATION STATEMENT ON FORM S-1
          (REGISTRATION NO. 333-37159)


Gentlemen:

          We are acting as counsel to IOMED, Inc., a Utah corporation (the
"Company"), in connection with the preparation of the above-referenced
Registration Statement on Form S-2 (the "Registration Statement"), filed by the
Company with the Securities and Exchange Commission (the "Commission") on
October 3, 1997. The Registration Statement relates to the registration under
the Securities Act of 1933, as amended (the "Act"), of up to 1,700,000 common
shares (the "Shares") of no par value, to be issued and sold pursuant to an
underwriting agreement to be entered into among the Company and EVEREN
Securities, Inc., Hanifen, Imhoff Inc. and Wedbush Morgan Securities, on behalf
of themselves and the several other underwriters to be named in Schedule I
thereto (the "Underwriting Agreement"). Capitalization terms used herein and not
otherwise defined have the meanings given to them in the Registration Statement.

          This opinion is delivered in accordance with the requirements of Item
601(b)(5) of Regulation S-K promulgated under the Act.

          In connection with this opinion, we have examined and are familiar
with originals or copies, certified or otherwise identified to our satisfaction,
of (i) the Amended and Restated Articles of Incorporation of the Company; (ii)
the By-laws of the Company as amended to date;

(iii) certain resolutions and written consents of the Board of Directors of the
Company relating to the offering of the Shares; (iv) the Registration
Statement, and (v) such other documents as we have deemed necessary or
appropriate as the basis for the opinions set forth below. In such examination,
we have assumed the genuineness of all signatures, the legal capacity of
natural persons, the authenticity of all documents submitted to us as
originals, the conformity to original documents of all documents submitted to
us as certified or photostatic copies and the authenticity of the originals of
such latter documents. As to any facts material to this opinion which we did
not independently establish or verify, we have relied upon statements and
representations of officers and other representatives of the Company and others.

        Members of our firm are admitted to the practice of law in the State of
Utah, and we express no opinion as to the laws of any other jurisdiction.

        Based upon and subject to the foregoing, we are of the opinion that
when (i) the Registration Statement becomes effective, (ii) the Underwriting
Agreement is duly executed and delivered by the Company and the other parties
thereto and (iii) certificates representing the Shares are duly executed,
countersigned, registered and duly delivered upon payment of the agreed upon
consideration therefor, the Shares will be duly authorized, validly issued,
fully paid and non-assessable.

        We hereby consent to the filing of this opinion with the Commission as
Exhibit 5.1 to the Registration Statement. We also consent to the reference to
our firm under the caption "Legal Matters" in the Registration Statement. In
giving this consent, we do not thereby admit that we are included in the
category of persons whose consent is required under Section 7 of the Act or the
rules and regulations of the Commission.

                                        Very truly yours,



                                        Parsons Behle & Latimer

ARTICLE II: THE LICENSE

1.1.  ELAN shall remain proprietor of all the ELAN IONTOPHORETIC INTELLECTUAL
      PROPERTY but hereby grants to IOMED for the term of the Agreement an
      exclusive (including as to ELAN) license in the TERRITORY, with the right
      to grant sublicenses pursuant to and in accordance with the provisions of
      Article II Paragraph 2, to research develop, manufacture, have
      manufactured for IOMED (or its permitted sublicenses), use, sell and
      otherwise commercialize the ELAN IONTOPHORETIC INTELLECTUAL PROPERTY and
      the PRODUCTS in the FIELD under the terms and conditions set out herein.
      The exclusive nature of the licenses granted by ELAN are subject to 
      **** as set out in Appendix C.  ELAN's license to IOMED shall specifically
      exclude ELAN EXCLUDED TECHNOLOGY.

1.2.  Subject to earlier termination of the Agreement pursuant to Article VIII,
      at the end of the ADDITIONAL TERM the rights granted by ELAN to IOMED
      pursuant to Paragraph 1.1 above shall be exclusive, paid-up and
      irrevocable.

2.1.  IOMED may sublicense rights which incorporate the ELAN IONTOPHORETIC
      INTELLECTUAL PROPERTY ****, without the prior written consent of ELAN.
<PAGE>   9
2.2.  Any sublicense other than permitted by paragraph 2.1. above, ****, shall
      require the prior written consent of ELAN, which may be withheld in the
      sole discretion of ELAN.

2.3.  No sublicense granted by IOMED pursuant to Article II Paragraph 2 shall
      authorize or permit the sublicense to grant further sublicenses ****.
      IOMED shall use its reasonable endeavors to ensure that ELAN shall have
      the same rights of audit and inspection vis a vis the sublicensee as ELAN
      has pursuant to this Agreement concerning IOMED.

2.4.  Insofar as the obligations owed by IOMED to ELAN are concerned, IOMED
      shall remain responsible for all acts and omissions of any sublicenses as
      if such acts and omissions were by IOMED; provided that no such acts or
      omissions of such sublicensee will constitute a material breach by IOMED
      for the purpose of Article VIII Paragraph 3.  In the event that ELAN
      terminates the Agreement pursuant to the provisions of Article VIII
      Paragraph 3, due to the default of IOMED, then ELAN shall, with IOMED's
      consent and assistance, notify each sublicensee appointed pursuant to
      Article II Paragraphs 2.1. and 2.2. of its termination.  If any
      sublicensee elects to notify ELAN that it requires the continuation of the
      licenses granted to IOMED pursuant to this Agreement, ELAN shall promptly
      enter into good faith negotiations with sublicensee to establish a direct
      contractual nexus between ELAN and such sublicensee.  Such contractual
      nexus shall, subject to ELAN's reasonable discretion, be on commercially
      reasonable terms and shall to the extent practicable be on terms no less
      favorable to the sublicensee than the terms of such sublicensees'
      agreement with IOMED, and shall provide that the sublicensee shall take
      over the applicable obligations owed by IOMED to ELAN pursuant to this
      Agreement.  Sales of PRODUCTS and other consideration payable to such a
      sublicensee in relation to the PRODUCTS shall constitute NET REVENUES for
      the purpose of calculating the sums payable by the sublicensee to ELAN.
      ****.

3.    It is contemplated that the physical transfer of the ELAN IONTOPHORETIC
      KNOW-HOW to be licensed under this Agreement and the furnishing of copies

      RIGHTS shall be completed within six months of the EFFECTIVE DATE.  ELAN
      shall, at its expense, provide all reasonable assistance within such

      Parties shall negotiate in good faith reimbursement of ELAN's
      out-of-pocket expenses.  Any dispute under this Paragraph 3 shall be
      resolved by referring such dispute to an arbitrator pursuant to the

      entitled to disclose such CONFIDENTIAL INFORMATION as ELAN considers
      reasonably necessary in using such commercially reasonable endeavors to
      potential sublicensees under obligations of confidentiality.  As of the
      date hereof (I) ELAN has no such sublicensees and (II) to the knowledge of
      ELAN, there are currently no grounds to cite such patents and there are no

      and in accordance with the provisions of such agreement and subject to
      the provisions of any product-specific sublicense agreements entered into
      by ELAN, including the agreement referred to in Article II Paragraph 10.
      During the Negotiation Period, the Parties shall negotiate in good faith
      the terms of a sublicense. It is agreed that this paragraph creates no
      legal obligation upon either Party to conclude the sublicense agreement,

      or developed solely by IOMED employees shall be owned by IOMED. Title to
      all inventions and other intellectual property created or developed
      jointly by employees of IOMED and ELAN pursuant to research and
      development conducted by ELAN and IOMED pursuant to Article III shall be
      jointly owned by ELAN and IOMED. The Parties agree that such inventions
      invented after the EFFECTIVE DATE shall not result in any additional
      royalties being paid by IOMED pursuant to Article IV or extend the TERM
      of this Agreement.

2.    The Parties agree that the following provisions of Article VII Paragraph
      2. shall apply as regards the filing, prosecution and Maintenance of the
      ELAN IONTOPHORETIC PATENT RIGHTS:
<PAGE>   20

2.1.      IOMED at its expense shall be responsible to secure the grant of the
          ELAN IONTOPHORETIC PATENT RIGHTS and to file patent applications
          covering any improvements, to prosecute and defend such applications
          against independent third party oppositions; and upon grant of any
          letters patent covering such invention, to maintain such letters
          patent in force. IOMED at its expense shall have the right to control
          such filing, prosecution, defence and maintenance; provided however
          ELAN shall be provided with copies of all substantive documents
          relating to such filing, prosecution and defence in sufficient time to
          review such documents and comment thereon prior to any deadline for
          filing the same, if desired by ELAN. IOMED shall be entitled to
          determine the patent filing strategy. ELAN shall execute all
          documents, forms and declarations and otherwise co-operate fully to
          enable IOMED to seek and obtain the broadest protection afforded by
          the patent laws of the countries within the TERRITORY, whether during
          the TERM of this Agreement or thereafter. For the avoidance of doubt,
          the Parties agree that all information furnished to ELAN pursuant to
          this Paragraph shall constitute CONFIDENTIAL INFORMATION for the
          purposes of this Agreement.

2.2.      If IOMED does not intend to make an application for patents or
          continue prosecution of a pending application in respect of the ELAN
          IONTOPHORETIC INTELLECTUAL PROPERTY in any or some (specifying which
          countries of the TERRITORY, or fails within six (6) months of
          disclosure under Article VII Paragraph 2.1. to make application in
          one or more countries of the TERRITORY, ELAN shall have the option
          and the right to apply for patents or other intellectual property
          protection in respect thereof (in the countries where IOMED has not
          applied). If IOMED does not intend to continue prosecution of a
          pending application in any country of the TERRITORY, IOMED shall
          promptly inform ELAN of such a decision and no later than in
          sufficient time for ELAN to continue such prosecution. For the
          avoidance of doubt, the Parties agree that such patents as are
          obtained by ELAN pursuant to this Paragraph shall constitute ELAN 
          IONTOPHORETIC PATENT RIGHTS.

2.3       ELAN shall use its commercially reasonable endeavours to ensure that
          the inventors of the ELAN IONTOPHORETIC PATENT RIGHTS shall be
          reasonably available to IOMED to deal with queries, and complete and
          execute documents, relating to the filing, prosecution and defence of
          the ELAN IONTOPHORETIC PATENT RIGHTS.

ARTICLE VIII: TERM AND TERMINATION

1.   This Agreement is concluded for a period commencing as of the date of this
Agreement and shall expire on a country by country basis fifteen (15) years
starting from the EFFECTIVE DATE, or for the life of the last to expire patent
included in the ELAN IONTOPHORETIC PATENT RIGHTS and the DDS IONTOPHORETIC
PATENT RIGHTS which are used in the exploitation of the PRODUCTS, whichever is
longer ("the TERM"). From and after the tenth year of the TERM, in the event
that IOMED reasonably believes that there are ELAN IONTOPHORETIC PATENT
RIGHT(s) that are not used in connection with the exploitation of the PRODUCTS,
IOMED shall provide written notice thereof to ELAN, setting forth in reasonable
detail its reasons therefor.

Elan and IOMED shall thereupon each in good faith attempt to make a joint
determination of whether IOMED's conclusion is correct or if such ELAN
IONTOPHORETIC PATENT RIGHT(S) are in fact used in connection with such
exploitation; if the Parties are unable to agree upon such joint determination
within 90 days of such notice from IOMED, either party shall have the right to
have such matter arbitrated. Such arbitration shall be conducted before an
independent patent attorney reasonably selected by the Parties, or on such
other basis as shall be mutually reasonably agreeable, pursuant to the
provisions of Article IX Paragraph 14.

2.4. IOMED shall not abandon an ELAN IONTOPHORETIC PATENT RIGHT without the
     prior written consent of ELAN, which shall not be unreasonably withheld. In
     the event that the Parties agree that IOMED may abandon such an ELAN
     IONTOPHORETIC PATENT RIGHT, ELAN shall have the right to take over the
     prosecution and maintenance of such ELAN IONTOPHORETIC PATENT RIGHTS, which
     rights shall no longer form a part of and be covered by the licenses
     granted by ELAN pursuant to this Agreement.

3.   IOMED and ELAN shall promptly inform the other in writing of any alleged
     infringement of which it shall become aware by a third party of any patents
     within the ELAN IONTOPHORETIC PATENT RIGHTS and provide such other with any
     available evidence of infringement.

4.   During the TERM and the ADDITIONAL TERM, IOMED shall have the right to
     pursue at its own expense and for its own benefit any such infringements of
     the ELAN IONTOPHORETIC PATENT RIGHTS and/or the IOMED PATENT RIGHTS. ELAN
     shall agree to be named as a necessary party in an action brought by and
     fully financed by IOMED and will reasonably co-operate with such action.
     Any expenses borne by ELAN shall be reimbursed by IOMED. Any recovery
     remaining after the deduction by IOMED of the reasonable expenses
     (including attorney's fees and expenses) incurred in relation to such an
     infringement proceeding shall constitute NET REVENUES for the purpose of
     this Agreement. Should IOMED decide not to pursue such infringers of the
     ELAN IONTOPHORETIC PATENT RIGHTS, ELAN may do so at its expense and for its
     own benefit, and IOMED will reasonably co-operate with such action. Any
     expenses borne by IOMED in co-operating with such action shall be
     reimbursed by ELAN.

      ****.

2.    In addition, for a period of five years commencing upon the expiration of
      the TERM ("the ADDITIONAL TERM"), the licenses granted by ELAN pursuant to
      Article II shall continue, provided, that the royalties payable during the
      ADDITIONAL TERM to ELAN referred to in Article IV shall be fifty percent
      (50%) of the amount otherwise payable during the TERM; thereafter, IOMED
      shall have an exclusive paid-up royalty-free license to the ELAN
      IONTROPHORETIC KNOW-HOW.

3.    In addition to the rights of early or premature termination provided for
      elsewhere in this Agreement, in the event that any of the term or
      provisions hereof are incurably breached by either Party, the
      non-breaching Party may immediately terminate this Agreement by written
      notice.  An incurable breach shall be committed when either Party is
      dissolved, liquidated, discontinued, becomes insolvent or when any
      proceeding is filed or commenced by either Party under bankruptcy,
      insolvency or debtor relief laws (and not dismissed within ninety (90)
      days).  Subject to the other provisions of this Agreement in the event of
      any other material breach, the non-breaching Party may terminate this
      Agreement by the giving of written notice to the breaching Party that this
      Agreement will terminate on the ninetieth (90th) day from notice unless
      cure is sooner effected.  If the breaching Party has proposed a course of
      action to rectify the breach and is acting in good faith to rectify same
      but has not cured the breach by the ninetieth (90th) day, the said period
      shall be extended by such period as is reasonably necessary to permit the
      breach to be rectified.  In the event that a Party is entitled to
      terminate this Agreement, such Party shall also be entitled to terminate
      the DDS AGREEMENT.  Furthermore in the event that a Party is entitled to
      terminate the DDS AGREEMENT, such Party shall also be entitled to
      terminate this Agreement.  In the event that the breaching Party disputes
      the validity of the of the right of the non-breaching Party to terminate
      the Agreement pursuant to this Paragraph, either Party may refer the
      dispute to an arbitrator pursuant to the provisions of Article IX
      Paragraph 14. Pending the determination of the arbitrator, neither Party
      may regard the Agreement as having been terminated and in particular shall
      not allege or claim to any third party that the Agreement has been
      terminated pursuant to this Paragraph.


     
<PAGE>   23




4.    In the event that IOMED elects to proceed against ELAN for damages in
      circumstances where IOMED would have been entitled to terminate the
      Agreement pursuant to Article IX Paragraph 3 and IOMED obtains a final
      order for damages from a court of competent jurisdiction which is not
      subject of further appeal, IOMED may offset the said order for damages
      against sums otherwise due to ELAN pursuant to Article IV until recovery
      of the said judgment.

5.    Upon termination of the Agreement:

      5.1.  any sums that were due from IOMED to ELAN prior to the exercise of
            the right to terminate this Agreement shall be paid in full within
            sixty (60) days of termination of this Agreement;

      5.2.  all confidentiality provisions (other than the obligations set out
            in Article IX Paragraph 1.1, as they effect ELAN in the event of
            termination of this Agreement by ELAN pursuant to Article VIII
            Paragraph 3 due to the breach by IOMED) set out in this Agreement
            shall remain in full force and effect for a period of five years;

      5.3.  all responsibilities and warranties shall insofar are appropriate
            remain in full force and effect;

      5.4.  the rights of inspection and audit shall continue in force for the
            period referred to in the relevant provisions of this Agreement;

      5.5   termination of this Agreement for any reason shall not release any
            Party hereto from any liability which, at the time of such
            termination has already accrued to the other Party or which is
            attributable to a period prior to such termination nor preclude
            either party from pursuing all rights and remedies it may have
            hereunder or at law or in equity with respect to any breach of this
            Agreement;

      5.6   in the event of termination of this Agreement by ELAN or IOMED
            pursuant to Article VIII Paragraph 3, IOMED and ELAN shall promptly
            return to the other Party all CONFIDENTIAL INFORMATION received from
            the other Party (except one copy of which may be retained for
            archival purposes);


           
<PAGE>   24




      5.7   in the event this Agreement is terminated by ELAN or IOMED pursuant
            to Article VIII Paragraph 3, IOMED and its sublicensees shall have
            the right for a period of **** from termination to sell or
            otherwise dispose of the stock of any PRODUCTS then on hand, which
            such sale shall be subject to Article IV and the other applicable
            terms of this Agreement.  The foregoing provisions of this Paragraph
            shall be subject to the Provisions of such agreement or agreements
            as ELAN and one or more sublicensees conclude pursuant to Article II
            Paragraph 2.4;

      5.8   in the event this Agreement is terminated by ELAN or IOMED pursuant
            to Article VIII Paragraph 3, the licenses granted by ELAN to IOMED
            shall terminate and ELAN shall thenceforth be entitled to exploit
            the ELAN INTELLECTUAL PROPERTY together with any improvements made
            by IOMED to the ELAN INTELLECTUAL PROPERTY; provided that the
            foregoing provision shall be subject to the provisions of Article II
            Paragraph 2.4. and any agreements entered into pursuant to the said
            Paragraph, and


      5.9.  Articles I, Article II Paragraph 2.4, Article VI, Article VII
            Paragraph 1, Article VIII and Article IX (other than Paragraph 3
            thereof) shall survive the termination or expiration of this
            Agreement for any reason.

ARTICLE IX: SUNDRY CLAUSES

1.    Secrecy

1.1.  Each of the parties agrees, during the TERM and the ADDITIONAL TERM, to
      hold in confidence and not disclose to any third parties, including any of
      the OFFERING PARTIES, except to the extent required by applicable law or
      administrative or judicial process, the ELAN IONTOPHORETIC INTELLECTUAL
      PROPERTY or the contents or nature thereof, provided, that the foregoing
      covenant shall not be applicable to ELAN in the event that the foregoing
      covenant shall not be applicable to ELAN in the event that IOMED (i)
      abandons or (ii) ceases to develop or commercialize (and provides notice
      thereof to ELAN) any such ELAN IONTOPHORETIC INTELLECTUAL PROPERTY and
      ELAN determines subsequently to develop products or technologies based on
      such ELAN IONTOPHORETIC INTELLECTUAL PROPERTY, irrespective of whether it
      is reduced to patent.


     
<PAGE>   25




      Each Party may make such disclosure to its directors, officers and agents
      and, in the case of IOMED, its potential and actual sublicensees and other
      parties to whom such disclosure is appropriate to enable IOMED to conduct
      its regular business (each of whom shall be bound by IOMED's disclosure
      agreements), who shall be informed of such confidentiality obligation and
      for whose breach the disclosing party shall be responsible.

1.2.  Subject to the provisions of Paragraph 1. 1., any whether written or oral
      (oral information shall be reduced to writing within one month by the
      Party giving the oral information and the written form shall be furnished
      to the other Party) pertaining to the ELAN IONTOPHORETIC INTELLECTUAL
      PROPERTY or the PRODUCTS that has been or will be communicated or
      delivered by ELAN to IOMED, and any information from time to time
      communicated or delivered by IOMED to ELAN, including without limitation,
      trade secrets, business methods, and cost, supplier, manufacturing and
      customer information, shall be treated by IOMED and ELAN, respectively, as
      CONFIDENTIAL INFORMATION, and shall not be disclosed or revealed to any
      third Party whatsoever or used in any manner except as expressly provided
      for  herein; provided, however, that such CONFIDENTIAL INFORMATION shall
      not be subject to the restrictions and prohibitions set forth in this
      section to the extent that such CONFIDENTIAL INFORMATION:

      1.2.1.  is available to the public in public literature or otherwise, or
              after disclosure by one Party to the other becomes public
              knowledge through no default of the Party receiving such
              information; or

      1.2.2.  was known to the Party receiving such information prior to the
              receipt of such information by such Party, whether received before
              or after the date of this Agreement; or

      1.2.3.  is obtained by the Party receiving such information from a third
              party not subject to a requirement of confidentiality with respect
              to such information; or

      1.2.4.  is required to be disclosed pursuant to: (A) any order of a court
              having jurisdiction and power to order such information to be
              released or made public; or (B) other requirement of law, provided
              that if the receiving Party becomes legally required to disclose
              any CONFIDENTIAL INFORMATION, the receiving Party shall give the
              disclosing Party prompt notice of such fact so that the disclosing
              Party may obtain a protective order or other appropriate remedy
              concerning any such disclosure.


             
<PAGE>   26




              The receiving Party shall fully cooperate with the disclosing
              Party in connection with the disclosing Party's efforts to obtain
              any such order or other remedy.  If any such order or other remedy
              does not fully preclude disclosure, the receiving Party shall make
              such disclosure only to the extent that such disclosure is legally
              required; or

      1.2.5.  is independently developed by or for the Party by persons not
              having access to the CONFIDENTIAL INFORMATION of the other Party.

1.3.  Each Party shall take all such precautions as it normally takes with its
      own CONFIDENTIAL INFORMATION to prevent any improper disclosure of such
      CONFIDENTIAL INFORMATION to any third Party, provided however, that such
      CONFIDENTIAL INFORMATION may be disclosed within the limits required to
      obtain any authorization from the FDA or any other United States of
      America or foreign governmental or regulatory agency or, with the prior
      written consent of the other Party, which shall not be unreasonably
      withheld, or as may otherwise be required in connection with the purposes
      of this Agreement.

1.4.  IOMED agrees that it will not use, directly or indirectly, any ELAN
      IONTOPHORETIC INTELLECTUAL PROPERTY, or other CONFIDENTIAL INFORMATION
      disclosed to IOMED or obtained from ELAN pursuant to this Agreement, other
      than as expressly provided herein.  ELAN agrees that it will not use,
      directly or indirectly, any IOMED KNOW-HOW, IOMED PATENT RIGHTS or other
      CONFIDENTIAL INFORMATION disclosed to ELAN or obtained from IOMED pursuant
      to this Agreement, other than as expressly provided herein.

1.5   IOMED and ELAN will not publicize the existence of this Agreement in any
      way without the prior written consent of the other subject to the
      disclosure requirements of applicable laws and regulations.  In the event
      that either Party wishes to make an announcement concerning the Agreement,
      that Party will seek the consent of the other Party.  The terms of any
      such announcement shall be agreed in good faith.

2.    Assignments/Subcontracting

      IOMED may not assign (other than by operation of law in the event of an
      acquisition of IOMED, or a merger or similar transaction, subject to the
      provisions as set forth in Article IX  Paragraph 3) the rights licensed by
      ELAN under Article II without the prior written consent of ELAN, which may
      be withheld in ELAN's sole discretion.  ELAN shall be entitled to assign
      its rights and obligations to an AFFILIATE.

    
<PAGE>   27





      ELAN may not assign to an unaffiliated third party (other than by
      operation of law in the event of an acquisition of ELAN, or a merger or
      similar transaction) its rights under this Agreement without the prior
      written consent of IOMED, which may be withheld in IOMED's sole
      discretion.

3.    Certain Changes of Control.

      In the event that an OFFERING PARTY makes or signifies its intention of
      make a bona fide offer which would result in such a party owning,
      directly or indirectly, more than fifteen per cent (15%) of IOMED's
      voting stock, on a fully-diulted basis, or otherwise controlling the
      IOMED's Board of Directors, or otherwise obtains substantial contractual
      rights pursuant to an agreement with IOMED to the ELAN IONTOPHORETIC
      INTELLECTUAL PROPERTY (as reasonably determined by ELAN) (each, a
      "Control Transaction"), IOMED shall (x) not accept such offer until it
      shall have complied with the remaining provision of this Paragraph
      without ELAN's consent (in its sole discretion) and (y) advise the
      appropriate OFFERING PARTY that, in lieu of IOMED accepting such offer,
      such OFFERING PARTY should make a separate offer with respect to that
      portion of IOMED's business that relates to the FIELD, and not to the
      remaining portion of IOMED's business. ELAN shall have a period of thirty
      (30) days to conduct appropriate due diligence and to determine whether
      it desires to match an offer made by an OFFERING PARTY with respect to
      that portion of IOMED's business that relates to the FIELD, (including
      the same economic, payment and other terms); it being understood that
      IOMED shall make available to ELAN reasonable and sufficient information
      to enable ELAN to conduct such due diligence.

      In the event that ELAN determines to make such offer, IOMED shall accept
      ELAN's offer and expeditiously consummate such transaction with ELAN.
      Notwithstanding the foregoing, in the event that an OFFERING PARTY
      consummates a Control Transaction without the consent of the IOMED's
      Board of Directors (as such Board is comprised at the time such
      transaction is first publicly announced or commenced) (including without
      limitation, in connection with a tender offer or offers or proxy
      solicitation), ELAN shall have the right in its sole discretion, to
      terminate the licences granted by ELAN pursuant to this Agreement,
      without payment or penalty to IOMED.

4.    Parties bound

      This Agreement shall be binding upon and enure for the benefit of Parties
      hereto, their successors and permitted assigns.


<PAGE>   28




5.    Severability

      If any provision in this Agreement is agreed by the Parties to be, or is
      deemed to be, or becomes invalid, illegal, void or unenforceable under any
      law that is applicable hereto, (i) such provision will be deemed amended
      to conform to applicable laws so as to be valid and enforceable or, if it
      cannot be so amended without materially altering the intention of the
      Parties, it will be deleted, with effect from the date of such agreement
      or such earlier date as the Parties may agree, and (ii) the validity,
      legality and enforceability of the remaining provisions of this Agreement
      shall not be impaired or affected in any way.

6.    Force Majeure

      Neither Party to this Agreement shall be liable for delay in the
      performance of any of its obligations hereunder if such delay results from
      cause beyond its reasonable control, including, without limitation, acts
      of God, fires, strikes, acts of war, or intervention of a Government
      Authority, non-availability of raw materials, but any such delay or
      failure shall be remedied by such Party as soon as practicable.

7.    Relationship of the Parties

      Nothing contained in this Agreement is intended or is to be construed to
      constitute ELAN and IOMED as partners or joint venturers or either Party
      as an employee of the other.  Neither Party hereto shall have any express
      or implied right or authority to assume or create any obligations on
      behalf of or in the name of the other Party or to bind the other Party to
      any contract, agreement or undertaking with any third party

8.    Amendments

      No amendment, modification or addition hereto shall be effective or
      binding on either Party unless set forth in writing and executed by a duly
      authorized representative of both Parties.

9.    Waiver

      No waiver of any right under this Agreement shall be deemed effective
      unless contained in a written document signed by the Party charged with
      such waiver, and no waiver of any breach or failure to perform shall be
      deemed to be a waiver of any future breach or failure to perform or of any
      right arising under this Agreement.

14.   Arbitration

      Any dispute under this Agreement which is not settled by mutual consent
      and which is the subject of an arbitration clause shall be finally settled
      by binding arbitration conducted in accordance with the Commercial
      Arbitration Rules of the American Arbitration Association by an arbitrator
      appointed in accordance with said rules.  The arbitration shall be held in
      New York, New York and the arbitrator shall be to the extent practicable
      experienced as to the subject matter of the dispute such as an independent
      expert in pharmaceutical product development and marketing (including
      clinical development and regulatory affairs) or an independent patent
      attorney as the case may be.  The arbitrator shall determine what
      discovery will be permitted, consistent with the goal of limiting the cost
      and time which the Parties must expend for discovery; provided the
      arbitrator shall permit such discovery as he deems necessary to permit an
      equitable resolution of the dispute.  Any written evidence originally in a
      language other than English shall be submitted in English translation
      accompanied by the original or a true copy thereof.  The costs of the
      arbitration, including administrative and arbitrator's fees, shall be
      shared equally by the Parties and each Party shall bear its own costs and
      attorneys' and witness' fees incurred in connection with the arbitration,
      provided that the prevailing Party may be awarded the reasonable costs and
      fees incurred in connection with the arbitration at the discretion of the
      arbitrator.


<PAGE>   31




      A disputed performance or suspended performance pending the resolution of
      the arbitration must be completed within thirty (30) days following the
      final decision of the arbitrators or such other reasonable period as the
      arbitrators determine in a written opinion.  Any arbitration subject to
      this Paragraph 14 shall be completed within one (1) year from the filing
      of notice of a request for such arbitration.  The arbitration proceedings
      and the decision shall not be made public without the joint consent of the
      Parties and each Party shall maintain the confidentiality of such
      proceedings and decision unless (a) otherwise permitted by the other Party
      or (b) otherwise required by the applicable law in which case the
      provisions of Article IX Paragraph 1.2.4. shall be applicable.  The
      Parties agree that the decision shall be the sole, exclusive and binding
      remedy between them regarding any and all disputes, controversies, claims
      and counterclaims presented to the arbitrators. Application may be made to
      any court having jurisdiction over the Party (or its assets) against whom
      the decision is rendered for a judicial recognition of the decision and an
      order of enforcement.

15.   Withholding

      Any income or other taxes which IOMED is required by law to pay or
      withhold on behalf of ELAN with respect to royalties and any other moneys
      payable to ELAN under this Agreement shall be deducted from the amount of
      such royalties and moneys due.  IOMED shall furnish ELAN with proof of
      such payments.  Any such tax required to be paid or withheld shall be an
      expense of and borne solely by ELAN.  IOMED shall promptly provide ELAN
      with a certificate or other documentary evidence to enable ELAN to support
      a claim for a refund or a foreign tax credit with respect to any such tax
      so withheld or deducted by IOMED.  Both Parties will reasonably cooperate
      in completing and filing documents required under the provisions of any
      applicable tax treaty or under any other applicable law, in order to
      enable IOMED to make such payments to ELAN without any deduction or
      withholding.

16.   Indemnity

16.1. ELAN shall indemnify, defend and hold harmless IOMED from all actions,
      losses, claims, demands, damages, costs and liabilities (including
      reasonable attorneys' fees) to which IOMED is or may become subject
      insofar as they arise out of or are alleged or claimed to arise out of any
      breach by ELAN of any of its obligations under this Agreement or
      warranties of ELAN.

16.2. IOMED shall indemnify, defend and hold harmless ELAN from all actions,
      losses, claims, demands, damages, costs and liabilities (including

      insofar as they arise out of or are alleged or claimed to arise out of
      any breach by IOMED of any of its obligations under this Agreement or
      warranties of IOMED. IOMED shall assume the sole and entire
      responsibility and shall indemnify and save harmless ELAN from any and
      all claims, liabilities, expenses, including reasonable attorney's fees,
      responsibilities and damages by reason of any claim, proceedings, action,
      liability or injury arising out of any defect in the PRODUCTS, including
      the manufacture, transport, packaging, storage, handling, distribution,
      marketing or sale of the PRODUCTS by IOMED.

16.3. As a condition of obtaining an indemnity in the circumstances set out
      above, the Party seeking an indemnity shall:

      16.3.1  fully and promptly notify the other Party of any claim or
              proceeding, or threatened claim or proceeding;

              such claim or proceeding;

      16.3.3. assist in the investigation and defence of such claim or
              proceeding;

      16.3.4. not compromise or otherwise settle any such claim or proceeding
              without the prior written consent of the other Party, which
              consent shall not be unreasonably withheld; and

      16.3.5. take all reasonable steps to mitigate any loss or liability in
              respect of any such claim or proceeding.

16.4. Notwithstanding anything to the contrary in this Agreement, ELAN and IOMED
      shall not be liable to the other by reason of any representation or
      warranty, condition or other term or any duty of common law, or under the
      express terms of this Agreement for any consequential or incidental loss
      or damage (whether for loss of profit or otherwise) and whether occasioned
      by the negligence of the respective Parties, their employees or agents or
      otherwise.

            shall not affect its construction or interpretation.

ARTICLE II: THE LICENSE

1.1.  DDS shall remain Proprietor of all the DDS IONTOPHORETIC PATENT RIGHTS but
      hereby grants to IOMED for the term of the Agreement an exclusive
      (including as to DDS) license in the TERRITORY, with the right to grant
      sublicenses pursuant to and in accordance with the provisions of Article
      II Paragraph 2, to research, develop, manufacture, have manufactured for
      IOMED (or its permitted sublicensees), use, sell and otherwise
      commercialize the DDS IONTOPHORETIC PATENT RIGHTS and the PRODUCTS in the
      FIELD under the terms and conditions set out herein.

1.2.  Subject to earlier termination of the Agreement pursuant to Article VIII,
      at the end of the ADDITIONAL TERM the rights granted by DDS to IOMED 
      pursuant to Paragraph 1.1 above shall be exclusive, paid-up and 
      irrevocable.

2.1.  IOMED may sublicense rights which incorporate the DDS IONTOPHORETIC PATENT
      RIGHTS ****, without the prior written consent of DDS .

2.2.  Any sublicense other than permitted by Paragraph 2. 1. above, ****,
      shall require the prior written consent of DDS, which may be withheld in

<PAGE>   8
2.3.  NO sublicense granted by IOMED pursuant to Article II Paragraph 2 shall
      authorize or permit the sublicensee to grant further sublicenses ****,
      IOMED shall use its reasonable endeavors to ensure that DDS shall have the
      same rights of audit and inspection vis a vis the sublicensee as DDS has
      pursuant to this Agreement concerning IOMED.

2.4.  Insofar as the obligations owed by IOMED to DDS are concerned, IOMED shall
      remain responsible for all acts and omissions of any sublicensee as if
      such acts and omissions were by IOMED; provided that no such acts or
      omissions of such sublicensee will constitute a material breach by IOMED
      for the purposes of Article VIII Paragraph 3.  In the event that DDS
      terminates the Agreement pursuant to the provisions of Article VIII
      Paragraph 3, due to the default of IOMED, then DDS shall, with IOMED's
      consent and assistance, notify each sublicensee appointed pursuant to
      Article II Paragraphs 2.1 and 2.2 of its termination.  If any sublicensee
      elects to notify DDS that it requires the continuation of the licenses
      granted to IOMED pursuant to this Agreement, DDS shall promptly enter into
      good faith negotiations with such sublicensee to establish a direct
      contractual nexus between DDS and such sublicensee.  Such contractual
      nexus shall subject to DDS's reasonable discretion be on commercially
      reasonable terms and shall to the extent practicable be on terms no less
      favorable to the to the sublicensee than the terms of such sublicensees'
      agreement with IOMED, and shall provide that the sublicensee shall take
      over the applicable obligations owed by IOMED to DDS pursuant to this
      Agreement.  Sales of PRODUCTS and other consideration payable to such a
      sublicensee in relation to the products shall constitute NET REVENUES for
      the purpose of calculating the sums payable by the sublicensee to DDS.  
      ****.

3.    It is contemplated that the furnishing of copies of relevant patent
      documentation regarding the DDS IONTOPHORETIC PATENT RIGHTS shall be
      completed within six months of the EFFECTIVE DATE.

      in such a manner as to ensure compliance with, and enforceability under,
      applicable laws.

      PERFORMANCE BY IOMED

      financial resources and capital constraints, to research, develop,

3.3.  All payments due hereunder shall be made in United States Dollars.
      Payments due on NET REVENUES received in a currency other than United

      exchange rates in effect for the purchase of United States Dollars with
      such foreign currency quoted in the Wall Street Journal (or comparable
      publication if not quoted in the Wall Street Journal) with respect to the
      currency of the country or origin of such payment for the last business
      day of each mouth for which the payment is being made.

      this Paragraph shall constitute CONFIDENTIAL INFORMATION for the purposes
      of this Agreement.

      Any adjustment required by such inspection shall be made within thirty
      (30) days of the agreement of the Parties or, if not agreed, upon the
      determination of an arbitrator to whom any dispute under this Paragraph
      shall be submitted to arbitration pursuant to Article IX Paragraph 14.  If
      the adjustment payable to DDS is greater than ****, then the cost to DDS
      for the inspection and if applicable the arbitration shall be paid by
      IOMED.  In addition, IOMED shall pay interest to DDS at **** (applicable
      as of the date on which payment should have been made pursuant to Article
      IV Paragraph 3.3.), from the date on which payment should have been made
      pursuant to Article IV Paragraph 3.3. until the date of payment.

      created or developed solely by employees of DDS shall be owned by DDS.
      Title to all inventions and other intellectual property created or
      developed solely by IOMED employees shall be owned by IOMED. The Parties
      agree that such inventions invented after the EFFECTIVE DATE shall not
      result in any additional royalties being paid by IOMED pursuant to
      Article IV or extend the TERM of this Agreement.

2.    The Parties agree that the following provisions of Article VII Paragraph
      2, shall apply as regards the filing, prosecution and maintenance of the
      DDS IONTOPHORETIC PATENT RIGHTS:

2.1.  IOMED at its expense shall be responsible to secure the grant of the DDS
      IONTOPHORETIC PATENT RIGHTS and to file patent applications covering any
      improvements, to prosecute and defend such applications against
      independent third party oppositions; and upon grant of any letters patent
      covering such invention, to maintain such letters patent in force. IOMED
      at its expense shall have the right to control such filing, prosecution,
      defence and maintenance; provided however DDS shall be provided with
      copies of all substantive documents relating to such filing, prosecution
      and defence and maintenance; provided however DDS shall be provided with
      copies of all substantive documents relating to such filing, prosecution
      and defence in sufficient time to review such documents and comment
      thereon prior to any deadline for filing the same, if desired by DDS.
      IOMED shall be entitled to determine the patent filing strategy. DDS
      shall execute all documents, forms and declarations and otherwise
      co-operate fully to enable IOMED to seek and obtain the broadest
      protection afforded by the patent laws of the countries within the

      INFORMATION for the purposes of this Agreement.

2.2.  If IOMED does not intend to make an application for patents or continue
      prosecution of a pending application in respect of the DDS IONTOPHORETIC
      PATENT RIGHTS in any or some (specifying which) countries of the
      TERRITORY, or fails within six (6) months of disclosure under Article
      VII Paragraph 2.1, to make application in one or more countries of the
      TERRITORY, DDS shall have the option and the right to apply for patents
      or other intellectual property protection in respect thereof (in the

      IONTOPHORETIC PATENT RIGHTS.

2.4.  IOMED shall not abandon an DDS IONTOPHORETIC PATENT RIGHT without the
      prior written consent of DDS, which shall not be unreasonably withheld.

      IONTOPHORETIC PATENT RIGHT, DDS shall have the right to take over the
      prosecution and maintenance of such DDS IONTOPHORETIC PATENT RIGHTS,
      which rights shall no longer form a part of and be covered by the
      licenses granted by DDS pursuant to this Agreement.

3.    IOMED and DDS shall promptly inform the other in writing of any alleged
      infringement of which it shall become aware by a third party of any

4.    During the TERM and the ADDITIONAL TERM, IOMED shall have the right to
      pursue at its own expense and for its own benefit any such infringements
      of the DDS IONTOPHORETIC PATENT RIGHTS and/or the IOMED PATENT RIGHTS.
      DDS shall agree to be named as a necessary party in an action brought by
      and fully financed by IOMED and will reasonably co-operate with such

      recovery remaining after the deduction by IOMED of the reasonable expenses
      (including attorney's fees and expenses) incurred in relation to such an
      infringement proceeding shall constitute NET REVENUES for the purpose of
      this Agreement. Should IOMED decide not to pursue such infringers of the
      DDS IONTOPHORETIC PATENT RIGHTS, DDS may do so at its expense and for its
      own benefit, and IOMED will reasonably co-operate with such action. Any
      expenses borne by IOMED in co-operating with such action shall be
      reimbursed by DDS.

      of the TERM, in the event that IOMED reasonably believes that there are
      DDS IONTOPHORETIC PATENT RIGHT(S) that are not used in connection with the
      exploitation of the PRODUCTS, IOMED shall provide written notice thereof
      to DDS, setting forth in reasonable detail its reasons therefor. DDS and
      IOMED shall thereupon each in good faith attempt to make a joint
      determination of whether IOMED's conclusion is correct or if such DDS
      IONTOPHORETIC PATENT RIGHT(S) are in fact used in connection with such
      exploitation; if the Parties are unable to agree upon such joint
      determination within ninety (90) days of such notice from IOMED, either
      party shall have the right to have such matter arbitrated. Such
      arbitration shall be conducted before an independent experienced patent
      attorney reasonably selected by the Parties, or on such other basis as
      shall be mutually reasonably agreeable, pursuant to the provisions of
      Article IX Paragraph 14.

      dissolved, liquidated, discontinued, becomes insolvent, or when any
      proceeding is filed or commenced by either Party under bankruptcy,
      insolvency or debtor relief laws (and not dismissed within ninety (90)
      days).  Subject to the other provisions of this Agreement, in the event of
      any other material breach, the non-breaching Party may terminate this
      Agreement by the giving of written notice to the breaching Party that this
      Agreement will terminate on the ninetieth (90th) day from notice unless
      cure is sooner effected.

      breach and is acting in good faith to rectify same but has not cured the
      breach by the ninetieth (90th) day, the said period shall be extended by
      such period as is reasonably necessary to permit the breach to be
      rectified. In the event that a Party is entitled to terminate this

      to this Paragraph, either Party may refer the dispute to an arbitrator
      pursuant to the provisions of Article IX Paragraph 14.  Pending the
      determination of the arbitrator, neither Party may regard the Agreement as
      having been terminated an in particular shall not allege or claim to any
      third party that the Agreement has been terminated pursuant to this
      Paragraph.

      circumstances where IOMED would have been entitled to terminate the
      Agreement pursuant to Article IX Paragraph 3 and IOMED obtains a final
      order for damages from a court of competent jurisdiction which is not
      subject of further appeal, IOMED may offset the said order for damages
      against sums other due to DDS pursuant to Article IV until recovery of the
      said judgment.

              knowledge through no default of the Party receiving such
              information; or


             
<PAGE>   22




      1.2.2.  was known to the Party receiving such information prior to the
              receipt of such information by such Party, whether received before
              or after the date of this Agreement; or

      1.2.3.  is obtained by the Party receiving such information from a third
              party not subject to a requirement of confidentiality with respect
              to such information; or

      1.2.4.  is required to be disclosed pursuant to: (A) any order of a court
              having jurisdiction and power to order such information to be
              released or made public; or (B) other requirement of law, provided
              that if the receiving Party becomes legally required to disclose
              any CONFIDENTIAL INFORMATION, the receiving Party shall give the
              disclosing Party prompt notice of such fact so that the disclosing
              Party may obtain a protective order or other appropriate remedy
              concerning any such disclosure.  The receiving Party shall fully
              cooperate with the disclosing Party in connection with the
              disclosing Party's efforts to obtain any such order or other
              remedy.  If any such order or other remedy does not fully preclude
              disclosure, the receiving Party shall make such disclosure only to
              the extent that such disclosure is legally required; or

      1.2.5.  is independently developed by or for the Party by persons not
              having access to the CONFIDENTIAL INFORMATION of the other Party.

1.3.  Each Party shall take all such precautions as it normally takes with its
      own CONFIDENTIAL INFORMATION to prevent any improper disclosure of such
      CONFIDENTIAL INFORMATION to any third party, provided, however, that such
      CONFIDENTIAL INFORMATION may be disclosed within the limits required to
      obtain any authorization from the FDA or any other United States of
      America or foreign governmental or regulatory agency or, with the prior
      written consent of the other Party, which shall not be unreasonably
      withheld, or as may otherwise be required in connection with the purposes
      of this Agreement.

1.4.  IOMED agrees that it will not use, directly or indirectly, any DDS
      IONTOPHORETIC PATENT RIGHTS, or other CONFIDENTIAL INFORMATION disclosed
      to IOMED or obtained from DDS pursuant to this Agreement, other than as
      expressly provided herein.  DDS agrees that it will not use, directly or
      indirectly, any IOMED KNOW-HOW, IOMED PATENT RIGHTS or other CONFIDENTIAL
      INFORMATION disclosed to DDS or obtained from IOMED pursuant to this
      Agreement, other than as expressly provided herein.
<PAGE>   23



1.5.  IOMED and DDS will not publicize the existence of this Agreement in any
      way without the prior written consent of the other subject to the
      disclosure requirements of applicable laws and regulations.  In the went
      that either Party wishes to make an announcement concerning the Agreement,
      that Party will seek the consent of the other Party, The terms of any such
      announcement be agreed in good faith.

2.    Assignments/Subcontracting

      IOMED may not assign (other than by operation of law in the event of an
      acquisition of IOMED. or a merger or similar transaction subject to the
      provisions as set forth in Article IX Paragraph 3) the rights licensed by
      DDS under Article II without the prior written consent of DDS , which may
      be withheld in DDS's sole discretion.  DDS shall be entitled to assign its
      rights and obligations to an AFFILIATE. DDS may not assign to an
      unaffiliated third party (other than by operation of law in the event of
      an acquisition of DDS, or a merger or similar transaction) its rights
      under this Agreement without the prior written consent of IOMED, which may
      be withheld in IOMED's sole discretion.

3.    Certain Changes of Control.

      In the event that an OFFERING PARTY makes or signifies its intention of
      make a bona fide offer which would result in such a party owning, directly
      or indirectly, more than fifteen per cent (15%) of IOMED's voting stock,
      on a fully-diluted basis, or otherwise controlling the IOMED's Board of
      Directors, or otherwise obtains substantial contractual rights pursuant to
      an agreement with IOMED to the DDS IONTOPHORETIC PATENT RIGHTS (as
      reasonably determined by DDS) (each, a "Control Transaction"), IOMED shall
      (x) not accept such offer until it shall have complied with the remaining
      provisions of this Paragraph without DDS's consent (in its sole
      discretion) and (y) advise the appropriate OFFERING PARTY that, in lieu of
      IOMED accepting such offer, such OFFERING PARTY should make a separate
      offer with respect to that portion of IOMED"s business that relates to the
      FIELD, and not to the remaining potion of IOMED's business. DDS and/or
      ELAN shall have a period of thirty (30) days to conduct appropriate due
      diligence and to determine whether it desires to match an offer made by an
      OFFERING PARTY with respect to that portion of IOMED's business that
      relates to the FIELD, (including the same economic, payment and other
      terms); it being understood that IOMED shall make available to DDS and/or
      ELAN reasonable and sufficient information to enable DDS and/or ELAN to
      conduct such due diligence. 

      In the event that DDS and/or ELAN determines to make such offer, IOMED
      shall accept such offer and expeditiously consummate such transaction with
      DDS and/or ELAN. Notwithstanding the foregoing, in the event that an
      OFFERING PARTY consummates a Control Transaction without the consent of
      the IOMED's Board of Directors (as such Board is comprised at the time
      such transaction is first publicly announced or commenced)(including
      without limitation, in connection with a tender offer or offers or proxy
      solicitation), DDS shall have the right in its sole discretion, to
      terminate the licences granted by DDS pursuant to this Agreement, without
      payment or penalty to IOMED.

      Any dispute under this Agreement which is not settled by mutual consent
      and which is the subject of an arbitration clause shall be finally settled
      by binding arbitration, conducted in accordance with the Commercial
      Arbitration Rules of the American Arbitration Association by an arbitrator

      experienced as to the subject matter of the dispute such as an independent
      expert in pharmaceutical product development and marketing (including
      clinical development and regulatory affairs) or an independent patent
      attorney as the case may be.  The arbitrator shall determine what
      discovery will be permitted, consistent with the goal of limiting the cost
      and time which the Parties must expend for discovery, provided the
      arbitrator shall permit such discovery as he deems necessary to permit an

      arbitrator.  A disputed performance or suspended performances pending the
      resolution of the arbitration must be completed within thirty (30) days
      following the final decision of the arbitrators or such other reasonable
      period as the arbitrators determine in a written opinion.  Any arbitration
      subject to this Paragraph 14 shall be completed within one (1) year from
      the filing of notice of a request for such arbitration.  The arbitration
      proceedings and the decision shall not be made public without the joint
      consent of the Parties and each Party shall maintain the confidentiality
      of such proceedings and decision unless (a) otherwise permitted by the
      other Party or (b) otherwise required by the applicable law in which case
      the Provisions of Article IX Paragraph 1.2.4. shall be applicable. The
      Parties agree that the decision shall be the sole, exclusive and binding
      remedy between them regarding any and all disputes, controversies, claims
      and counterclaims presented to the arbitrators. Application may be made to
      any court having jurisdiction over the Party (or its assets) against whom
      the decision is rendered for a judicial recognition of the decision and an
      order of enforcement.

                               LICENSE AGREEMENT

     THIS AGREEMENT is made upon the 27th day of December, 1996 and shall be

     1. LICENSES.
     (a) On the effective date of this Agreement, Iomed herewith grants to the

the "University Patents," the products described on Exhibit "B" hereto,
together with any improvements or additions thereto developed by the Licensee
or its "Sublicensees" (as hereinafter defined) after the effective date of this
Agreement, are referred to herein as the "University Products," and the
sublicense granted by this paragraph 1(a) is referred to herein as the

made or brought for patent, trademark or other infringement as the result of
the manufacture or sale of the University Products or the Iomed Products, such
Party shall promptly notify the other Party of such action.  The Licensee shall
have the first right, but not the obligation, to defend and to control the
defense of such Action, at its expense.  Iomed will assist the Licensee,
without cost to the Licensee, in the defense of such Action by providing
information and fact witnesses to the extent reasonably available.  Iomed shall
have the right to be represented in such Action by its own legal counsel, at
its own expense, provided that such legal counsel will act only in an advisory

party who has received and disclosed such information without the breach of any
obligation of confidentiality to Iomed or to any third party.  For purposes of
this paragraph 14, information shall not be deemed to be part of the public
domain or within the Licensee's knowledge merely because it may be embraced in
a more general disclosure, or because it may be derived from combinations of
information generally available to the public or otherwise within the
Licensee's knowledge.
     (b) The Licensee shall maintain all of the Confidential Information in
confidence and shall not, except as specifically permitted herein, disclose the
same to any third party (including without limitation affiliates of the

by law, in which case the Licensee shall notify Iomed, in writing, prior to
making such disclosure and shall cooperate with Iomed to preserve and protect

those of its employees who need to know the same in order to enable the
Licensee to utilize the Sublicense and the License, and to its permitted
Sublicensees; provided that each such person and entity is advised of the
obligations of confidentiality contained herein.  Any breach of the provisions
of this Paragraph 14(b) by such employees or Sublicensees shall be deemed, for
all purposes, to constitute a breach hereof by the Licensee.
     15. RELATIONSHIP OF THE PARTIES.  This Agreement shall not be deemed or
construed to create between Iomed and the Licensee the relationship of
principal and agent, joint venturers, co-partners, employer or employee, master

right or authority to bind or to act for or on behalf of the other Party.

                  3.1 Ciba Fields; Ciba Proprietary Drugs.

                  (a) Ciba Fields. Schedule 3.1(a) attached hereto sets forth as
of the date hereof those therapeutic fields in which Ciba or any of its
Affiliates ****************************************************************
***************************************************************************
***************************************************************************
Ciba may update Schedule 3.1(a) from time to time in its discretion during the
Exclusivity Period, subject to Section 3.1(c). The therapeutic fields set forth
on Schedule 3.1(a), as so updated from time to time, shall be referred to herein
as the "Ciba Fields."

                  (b) Ciba Proprietary Drugs. Schedule 3.1(b) attached hereto
sets forth as of the date hereof certain Drugs with respect ********************
*****************************************, and which Ciba believes are
potentially therapeutic if delivered pursuant to a System in the treatment of
the indication (the "Specified Indication") set forth in Schedule 3.1(b) with
respect to such Drug. Ciba may update Schedule 3.1(b) from time to time during
the term of this Agreement, subject to Section 3.1(c), ***********************
***************************************************************************
**********************************. The Drugs set forth on Schedule 3.1(b), as
so updated from time to time, shall be referred to herein as the "Ciba

                  (c) Updates. If Ciba desires at any time during the
Exclusivity Period to update Schedule 3.1(a) in order to include a new
therapeutic field (the "Proposed Ciba Field"), or at any time during the term of
this Agreement to update Schedule 3.1(b) to include a new Ciba Proprietary Drug
(such Drug, together with the associated Specified Indication, the "Proposed
Ciba 


                                       16
<PAGE>   21
Proprietary Drug"), it shall notify Dermion in writing, which notice shall
contain (i) in the case of a Proposed Ciba Field, a certification that such
Proposed Ciba Field satisfies the condition set forth in either clause (i) or
clause (ii) of Section 3.1(a) hereof, or (ii) in the case of a Proposed Ciba
Proprietary Drug, a certification that such Proposed Ciba Proprietary Drug
satisfies the condition set forth in Section 3.1(b) hereof. Such Proposed Ciba
Field or Proposed Ciba Proprietary Drug shall automatically and without further
action by any party hereto become a Ciba Field or a Ciba Proprietary Drug, as
the case may be, and be treated as such for all purposes of this Agreement
immediately upon receipt by Dermion of such written notice; provided, however,
that if Dermion has, prior to its receipt of such notice and in compliance with
the terms of this Agreement (including without limitation Section 3.3 hereof)
entered into an agreement with any other Person (a "Third Party Agreement") with
respect to the research, development, manufacture, distribution or sale of any
System to deliver a Drug in the Proposed Ciba Field or the Proposed Ciba
Proprietary Drug for treatment of the Specified Indication, such Third Party
Agreement shall not be subject to this Article 3.

                  (d) Removal of Ciba Field or Ciba Proprietary Drug. If, at any
time during the Exclusivity Period, any Ciba Field or, during the term of this
Agreement, any Ciba Proprietary Drug ceases to qualify as such, Ciba shall
within ninety (90) days notify Dermion in writing of such fact. Such Ciba Field
or Ciba Proprietary Drug, as the case may be, shall thereafter automatically and
without further action of the parties cease to be a Ciba Field or a Ciba
Proprietary Drug, as the case may be, for purposes of this Agreement.

                  3.2 Dermion Exclusivity. Dermion shall not conduct, have
conducted or fund any research or development activity with respect to, or
manufacture, distribute or sell (whether independently or on behalf of a third
party) any System for delivery of any Drug in a Ciba Field during the
Exclusivity Period or any Ciba Proprietary Drug for treatment of the Specified
Indication during the term of this Agreement, except (i) pursuant to the Program
in accordance with this Agreement, or (ii) outside the scope of the Program,
subject to compliance with Section 3.3.

                  3.3 Development of Systems for or by Dermion Outside the
Program.

                  (a) Notice of Dermion Proposed Systems. In the event that
during the Exclusivity Period Dermion determines to develop a System (including
any Abandoned Product) outside the scope of the Program, either pursuant to a
third party offer (a "Third 


                                       17
<PAGE>   22
Party Offer") to develop a System, or otherwise (a "Dermion Proposed System"),
Dermion shall give notice of the Dermion Proposed System to the Committee (the
"Notice"). The Notice shall include at least the therapeutic field of the drug
to be delivered pursuant to the Dermion Proposed System (the "Proposed Field"),
as well as such other information as is relevant to the Dermion Proposed System,
provided, that if the Dermion Proposed System is to be developed pursuant to a
Third Party Offer, Dermion shall not be required to disclose to the Committee
the name of such third party, the specific drug for which the System is to be
developed (unless such drug is a Ciba Proprietary Drug, in which case such drug,
as well as whether the indication proposed to be treated thereby is the
Specified Indication with respect to such drug, shall be disclosed) or any other
information that Dermion determines, in its good faith judgment, should not be
disclosed to Ciba because of confidentiality or competitive concerns (other than
the therapeutic field, which must in any event be disclosed).

                  (b) Dermion Proposed Systems in a Ciba Field. If the Proposed
Field is in whole or in part a Ciba Field, Dermion shall be prohibited from
pursuing the development of the Dermion Proposed System during the Exclusivity
Period without the prior written consent of Ciba, which may be given or withheld
in Ciba's sole discretion.

                  (c) Dermion Proposed Systems for Ciba Proprietary Drugs. If
the Dermion Proposed System relates to the delivery of a Ciba Proprietary Drug
for treatment of the Specified Indication, Ciba shall have the right during the
term of this Agreement to elect to have Dermion develop a Product for such Ciba
Proprietary Drug for treatment of the Specified Indication for it pursuant to
the Program instead of the Proposed Dermion System. If Ciba so elects, it shall
give notice thereof to the Committee within fifteen (15) Business Days of
receipt by the Committee of the Notice, in which case Dermion shall be
prohibited during the term of this Agreement from developing the Dermion
Proposed System for treatment of the Specified Indication, subject to the last
sentence of this Section 3.3 (c) The development of any such Product for a Ciba
Proprietary Drug for treatment of the Specified Indication pursuant to the
Program shall be pursuant to this Agreement or an amendment to this Agreement
(provided, that, other than providing for incremental costs to be paid by Ciba
and incremental personnel, facilities and resources to be provided by Dermion,
such amendment shall be on the same terms and conditions as this Agreement). If
Ciba fails to give such notice within such fifteen (15) Business Day period, or
if activities with respect to developing a Product for the Ciba Proprietary Drug
for treatment of the Specified Indication pursuant to the Program have not
commenced within 


                                       18
<PAGE>   23
ninety (90) days of receipt by the Committee of the Notice (other than as a
result of any acts or omissions of Dermion), Dermion shall be free to pursue the
development of the Dermion Proposed System for treatment of the Specified
Indication outside the scope of the Program, provided, that if activities with
respect to developing such Dermion Proposed System for treatment of the
Specified Indication outside the scope of the Program have not commenced within
ninety (90) days after expiration of such fifteen (15) Business Day period or
such ninety (90) day period, as the case may be, any activities by Dermion with
respect to such Dermion Proposed System shall thereafter be subject to
compliance with this Section 3.3.

                  (d) Other Dermion Proposed Systems. If the Proposed Field is
not a Ciba Field and if the Drug proposed to be delivered pursuant to the
Dermion Proposed System is not a Ciba Proprietary Drug for treatment of the
Specified Indication, Dermion may freely develop the Dermion Proposed System for
a third party (which development may be pursuant to an agreement under which
Dermion grants exclusive licenses to such third party).

                  3.4 Development by Dermion of Abandoned Products. Dermion
shall be entitled to pursue research concerning and development of Abandoned
Products outside the scope of the Program, provided, that (i) any such activity
shall be subject to compliance with Section 3.3, (ii) Patent Rights covering the
Drug for which such Abandoned Product was being developed or such drug's
manufacture or use shall have expired, and (iii) Dermion shall reimburse Ciba in
accordance with the next sentence for all costs and expenses previously incurred
in conducting Program activities with respect to such Abandoned Product. In 
reimbursement of such costs and expenses incurred with respect to any Abandoned
Product, Dermion shall pay to Ciba (i) within thirty (30) days after giving
Notice pursuant to Section 3.3(a) with respect to the proposed development by
Dermion of such Abandoned Product, all such costs and expenses up to a maximum
amount OF $250,000, and (ii) within thirty (30) days of receipt thereof, fifty
percent (50%) of all revenues received by Dermion with respect to such
Abandoned Product (including revenue from sales of and fees and/or royalties
received with respect to such Abandoned Product) up to the amount of such costs
and expenses not reimbursed pursuant to clause (i).


                  3.5      Development of Systems for or by Ciba.

                  (a) Systems for the Delivery of Ciba Proprietary Drugs. In the

<PAGE>   24
thereof to the Committee (a "Ciba Proposed Proprietary System"). Dermion shall
have the right to elect to develop such Ciba Proposed Proprietary System for
treatment of the Specified Indication as a Product pursuant to the Program. If
Dermion so elects, it shall give notice thereof to the Committee within fifteen
(15) Business Days of receipt by the Committee of such notice, in which case
Ciba shall be prohibited during the term of this Agreement from developing the
Ciba Proposed Proprietary System for treatment of the Specified Indication
outside the scope of the Program, subject to the last sentence of this Section
3.5(a). The development of a Ciba Proposed Proprietary System for treatment of
the Specified Indication as a Product pursuant to the Program shall be pursuant
to this Agreement or an amendment to this Agreement (provided, that, other than
providing for incremental costs to be paid by Ciba and incremental personnel,
facilities and resources to be provided by Dermion, such amendment shall be on
the same terms and conditions as this Agreement). If Dermion fails to give such
notice within such fifteen (15) Business Day period, or if activities with
respect to developing a Product for the Ciba Proprietary Drug for treatment of
the Specified Indication have not commenced within ninety (90) days of receipt
by the Committee of such notice (other than as a result of any acts or omissions
of Ciba), Ciba shall be free to pursue the development of the Ciba Proposed
Proprietary System for treatment of the Specified Indication outside the scope
of the Program, provided, that if activities with respect to developing such
Ciba Proposed Proprietary System for treatment of the Specified Indication
outside the scope of the Program have not commenced within ninety (90) days
after the expiration of such fifteen (15) Business Day period or such ninety
(90) day period, as the case may be, any activities by Ciba with respect to such
Ciba Proposed Proprietary System shall thereafter be subject to compliance with
this Section 3.5(a).

                  (b) Other Systems. If during the term of this Agreement Ciba
makes the determination to engage a third party (other than Dermion) to develop
a System for a Drug owned, licensed or manufactured by Ciba (other than a Ciba
Proprietary Drug for treatment of the Specified Indication, which shall be
covered by Section 3.5(a) above) (a "Ciba Proposed System"), prior to initiating
discussions with such third party, Ciba shall notify Dermion in writing. Ciba
agrees for a period of thirty (30) days from such notice (the "Ciba Standstill
Period"), (i) to negotiate in good faith with Dermion to reach an agreement
under which Dermion would develop the Ciba Proposed System for Ciba either
pursuant to this Agreement or an amendment to this Agreement (provided, that,
other than providing for incremental costs to be paid by Ciba and incremental
personnel, facilities and resources to be provided by Dermion, such amendment
shall be on the same terms and conditions as this Agreement), and 


                                       20
<PAGE>   25
(ii) Ciba shall not negotiate with or enter into a binding agreement with any
third party for the development of such Ciba Proposed System. If, upon
expiration of the Ciba Standstill Period, Ciba and Dermion have not reached an
agreement with regard to the development of the Ciba Proposed System, Ciba shall
be free to negotiate with and to enter into an agreement with a third party to
develop the Ciba Proposed System. Notwithstanding the foregoing, this Section
3.5(b) shall not apply to any Ciba Proposed System to the extent that
discussions regarding the development of such Ciba Proposed System are initiated
by a third party.

                  (c) No Other Restrictions. Notwithstanding any other provision
of this Agreement, Ciba shall be free to pursue the development of any System
(including any Ciba Proposed System) independently without the assistance of a
third party at any time without complying with Section 3.5(b) or any other
provision of this Agreement (other than Section 3.5(a) which shall apply only in
the case of a Ciba Proposed Proprietary System), and without any other
restriction or limitation of any kind.

                  4.5      Patents and Patent Applications.

                  (a) Initial Filings. Each party shall promptly disclose to the
Committee the conception or reduction to practice of any Jointly Developed
Technology that the disclosing party believes has a reasonable likelihood of
receiving patent protection. Promptly after such disclosure, the Committee shall
meet (in person or by teleconference) to discuss such Jointly Developed
Technology, including (i) whether to proceed with a patent application with
respect thereto and (ii) the jurisdictions in which such patent application
should be filed. In the event that the Committee elects to file a patent
application with respect to any Jointly Developed Technology, Ciba shall be
responsible therefor (unless the Committee determines that Dermion should file
such patent application (which determination shall not be a Ciba Matter)) (the
party filing such patent application being referred to in this Section 4.5 as
the "Responsible Party"). The Responsible Party shall (i) give the other party
an opportunity to review the text of any such application promptly (with
consideration of all applicable filing deadlines) before filing and (ii)
promptly supply the other party with a copy of the application as filed,
together with notice of its filing date and serial number. Unless otherwise
agreed by the parties, the Responsible Party shall be responsible for the
initial filing of any such patent application and the subsequent prosecution and
maintenance of the application and any resulting patents.

                  (b) Foreign Filings. Within a reasonable period of time (which
the parties shall use reasonable efforts to ensure is no more than nine (9)
months) following the filing date of a patent application pursuant to Section
4.4(a), the Committee shall determine whether to abandon such application
without replacement, abandon and refile such application, proceed with such
application only in the country of filing, or use such application (e.g. as the
basis for a claim of priority under the Paris Convention) for corresponding
applications in other countries. Dermion and Ciba shall consult together to
ensure that, so far as practicable, the texts of applications filed in different
jurisdictions contain the same information and claim the same scope of
protection.

                  (c) Patent Prosecution and Maintenance. The Responsible Party
shall diligently prosecute and maintain, using commercially reasonable
practices, patent applications and patents with respect to Jointly Developed
Technology for which it is responsible, and promptly provide the other party
with copies of all relevant documentation with respect thereto. The Responsible
Party shall use patent counsel and other professional 


                                       24
<PAGE>   29
advisors of its own selection, reasonably acceptable to the other party. The
Committee shall periodically review the status of patents and patent
applications constituting Jointly Developed Technology, including whether the
prosecution and/or maintenance of each such patent or patent application should
be continued.

                  (d) Authority. The Responsible Party shall have the sole and
exclusive authority to prosecute and maintain the patent application and patent
for which it is responsible, including the right to amend and cancel claimed
subject matter, as may be reasonably appropriate or desirable in the view of the
Responsible Party, but shall consult in good faith with the other party
regarding such prosecution and maintenance with respect to Jointly Developed
Technology for which it is responsible, and will promptly provide the other
party with a copy of all relevant documentation with respect thereto. The other
party shall cooperate with the Responsible Party, including providing the
Responsible Party with access to such information as may be reasonably necessary
to permit such prosecution and maintenance, and signing, or causing to have
signed, such documents as may be necessary or appropriate in connection
therewith. Prior to abandoning any such patent application or patent, the
Responsible Party shall offer the same to the other party for prosecution or
maintenance, as the case may be. The costs, if any, of such cooperation shall be
Prosecution Costs subject to Section 4.4(e).

                  (e) Prosecution Costs. Dermion and Ciba shall bear all
Prosecution Costs equally, provided, that Dermion's share of such Prosecution
Costs shall not exceed $50,000 per patent application (not including any
Premium payable pursuant to Section 4.5(f)).

                  (f) Independent Filing. In the event that after consideration
thereof the Committee elects not to file a patent application in any
Jurisdiction with respect to any Jointly Developed Technology, either Dermion or
Ciba shall be entitled to file a patent application in such jurisdiction with
respect to such Jointly Developed Technology (an "Independent Filing"). In such
event, the party making the Independent Filing shall bear all Prosecution Costs
with respect to such patent application and shall own all right, title and
interest in and to any Patent Rights arising or resulting from such Independent
Filing. Notwithstanding the foregoing, the other party may within one (1) year
of the filing date elect to join the filing party in such Independent Filing, in
which case (i) such other party shall pay to the filing party such other party's
share of Prosecution Costs incurred by the filing party to date in connection
with such Independent Filing plus an amount equal to ******************** (a
"Premium") of all such Prosecution Costs, (ii) all Patent Rights arising or
resulting from such filing shall be deemed


                                       25
<PAGE>   30
Jointly Developed Technology for all purposes under this Agreement, and (iii)
thereafter all of the other provisions of this Section 4.5 shall apply to such
patent application (with the filing party serving as the Responsible Party).

                  4.6      Infringement of Patent Rights.

                  (a) Notice. If any party shall become aware of any
infringement or threatened infringement of any Patent Rights constituting
Jointly Developed Technology or Licensed Technology, including that contained in
a notice provided under the 1984 Act by a party filing an ANDA or an NDA for a
System, or an equivalent action in any other country of the world (an
"Infringement"), then the party having such knowledge shall give notice
"Infringement Notice") to the other parties promptly upon becoming aware of such
Infringement.

                  (b) Jointly Developed Technology. Promptly upon receipt of any
Infringement Notice relating to Infringement of Jointly Developed Technology,
the Committee shall meet to determine appropriate action to take with respect to
such Infringement (the "Committee's Determination"), including (i) whether the
parties should prosecute such Infringement jointly, whether either party should
prosecute such Infringement independently, or whether no action should be taken
by the parties with respect to such Infringement, (ii) in the event that the
Committee determines to prosecute such Infringement jointly, the party or
parties to have primary responsibility therefor (the "Responsible Party(ies)"),
(iii) allocation between the parties of expenses to be incurred with respect to
the prosecution of such Infringement, (iv) allocation between the parties of any
damages recovered in respect of such Infringement, and (v) any other matter
deemed relevant by the Committee in respect of such Infringement. With respect
to any joint prosecution, the Responsible Party(ies) shall take such action, as
deemed appropriate, whether by action, suit, proceeding or otherwise, in
accordance with the Committee's Determination to prevent or eliminate the
Infringement and to collect damages with respect thereto. Except as set forth
below, all costs and expenses incurred by any party in connection with the
Infringement shall be borne by the parties in accordance with the Committee's
Determination. Except as set forth below, damages recovered by any party in such
action, suit or proceeding in connection with such Infringement shall be
apportioned between the parties in accordance with the Committee's
Determination. In the event that the Committee is unable to make a determination
mutually acceptable to the parties as to how to proceed with respect to such
Infringement, either party shall be entitled to prosecute such Infringement in
its own name and on its own behalf, in which case such party shall bear all
costs and expenses incurred by it 


                                       26
<PAGE>   31
in connection with prosecuting such Infringement and shall retain all damages
recovered in respect thereof.

                  (c) Licensed Technology. Each party shall be responsible to
take such action as it deems appropriate, whether by action, suit, proceeding or
otherwise, at its own expense to prevent or eliminate an Infringement of such
party's Licensed Technology and to collect damages, provided, that, with respect
to Patent Rights constituting Dermion Technology or IOMED Technology
incorporated in any Product (or in any process used in developing or
manufacturing any Product), Ciba shall have the right to prosecute such
infringement in the same manner and under the same terms and conditions as set
forth in Section 4.6(b).

                  4.7      Infringement of Third Party Rights.

                  (a) Notice. If either Dermion or Ciba shall become aware of
any Infringement Action with regard to the manufacture, use or sale of any
System incorporating (or developed or manufactured through processes
incorporating) Jointly Developed Technology, the party aware shall promptly
notify the other party of the same and fully disclose, to its knowledge, the
basis therefor.

                  (b) Infringement Actions with respect to Products. If the
Infringement Action relates to a Product incorporating (or developed or
manufactured through processes incorporating) Jointly Developed Technology, the
parties shall jointly compromise or defend the Infringement Action on such basis
and on such terms as the parties shall mutually agree. In such event the parties
shall cooperate fully with respect to the compromise or defense of such
Infringement Action, and each party shall keep the other fully informed as to
the status of such Infringement Action. If, in connection with such Infringement
Action, either Dermion or Ciba is required to obtain a Third Party License in
order to make, have made, use or sell Products incorporating (or developed or
manufactured through processes incorporating) Jointly Developed Technology, such
Third Party License shall be obtained for the benefit of both Dermion and Ciba,
and all rights under such Third Party License shall be held jointly by the
parties. All Settlement Costs incurred by the parties with respect to such
Infringement Action shall be borne eighty percent (80%) by Ciba and twenty
percent (20%) by Dermion.

                  (c) Infringement Actions with respect to Other Systems. If the
Infringement Action relates to a System incorporating (or developed or
manufactured through processes incorporating) Jointly Developed Technology,
which System is not a Product developed pursuant to the Program, the Committee
shall meet to determine appropriate action to take with respect to such


                                       27
<PAGE>   32
Infringement Action, including (i) whether the parties should compromise or
defend such Infringement jointly or whether either party should compromise or
defend such Infringement independently, (ii) in the event that the Committee
determines to compromise or defend such Infringement Action jointly, the party
or parties to have primary responsibility therefor, (iii) allocation between the
parties of expenses to be incurred with respect to the compromise or defense of
such prosecution, (iv) allocation between the parties of rights under any Third
Party License obtained in connection with such Infringement Action, and (v) any
other matter deemed relevant by the Committee in respect of such Infringement
Action. In the event that the Committee is unable to make a determination
mutually acceptable to the parties as to how to proceed with respect to such
Infringement Action, either party shall be entitled to compromise or defend such
Infringement Action in its own name and on its own behalf, in which case such
party shall bear all Settlement Costs incurred by it in connection with
compromising or defending such Infringement Action and shall retain sole
ownership of all rights under any Third Party License obtained by it in
connection with such Infringement Action.

of Dermion, which Dermion may give or withhold in its sole discretion.

                  5.4 Transfers of Second Generation Technology by Dermion. If
at any time during the term of this Agreement and for a period of five (5) years
after the effective date of termination thereof, Dermion obtains any Patent
Rights covering Second Generation Technology (as defined below), Dermion shall
notify Ciba in writing of such event. Dermion agrees that for a period of thirty
(30) days from such notice (the "Dermion Standstill Period"), (i) it will
negotiate in good faith with Ciba to reach an agreement to license the Second
Generation Technology to Ciba on terms and conditions acceptable to the parties,
and (ii) Dermion shall not negotiate or enter into a binding agreement with any
third party to Transfer the Second Generation Technology, provided, that clause
(ii) of this sentence shall only apply during the term of this Agreement. If,
upon expiration of the Dermion Standstill Period, Ciba and Dermion have not
reached an agreement for the license of such Second Generation Technology to
Ciba, Dermion shall be free to Transfer such Second Generation Technology to any
third party. In addition, if Ciba and Dermion have reached an agreement for a
license, Dermion shall also be free to Transfer such Second Generation
Technology to any third party to the extent permitted under the terms of the
license from Dermion to Ciba. Notwithstanding the foregoing, Dermion shall not
be required to enter into a license with Ciba if and to the extent that the
terms of such license would, in the good faith judgment of Dermion on advice of
counsel, violate the terms of any agreement between Dermion and any third party
then in effect. As used in this Section 5.4, "Second Generation Technology"
shall mean any technology (including Patent Rights and Know-How), other than
Improvements to Dermion Technology or IOMED Technology, developed by Dermion
that is applicable or potentially applicable to the development of Systems. If
any transaction is covered by both this Section 5.4 and Section 8.4 below, the
terms of Section 8.4 shall exclusively govern such transaction.

                  5.5 Future IOMED Licenses. Subject to Section 5.1(c), upon the
request of Dermion, IOMED shall grant a non-exclusive license of the IOMED
Technology to such licensee and on such terms and conditions as may be requested
by Dermion in connection 


                                       30

with the conduct of the Business by Dermion. IOMED acknowledges that all rights
to royalties payable in connection with any such license have been assigned to
Dermion pursuant to the Contribution Agreement.

revive effective immediately as of the date, if ever, that any such judgment,
decree or decision is overturned or otherwise modified such that any claim at
issue therein once again becomes valid and enforceable.

                  (e) Infringement of Third Party Rights. If, in connection with
any Infringement Action with regard to the manufacture, use or sale (either in
the United States (a "US Infringement Action") or outside the United States (a
"Non-US Infringement Action")) of any System incorporating (or developed or
manufactured through processes incorporating) Dermion Technology or IOMED
Technology, Ciba is required to obtain a Third Party License in order to make,
have made, use or sell any System, and/or to pay Settlement Costs in connection
with such Infringement Action, then, if and to the extent that that any such
consequence results from the incorporation of Dermion Technology or IOMED
Technology in such System, or from the development or manufacture of such System
through processes incorporating Dermion Technology or IOMED Technology, in
either case in compliance with the terms of this Agreement, any royalties
payable under this Section 6.4 with respect to such System shall be reduced by

Milestone Credits as a result of such reduction in royalties, Ciba shall be
entitled to reduce any amount payable under this Article 6 by the amount of such
unpaid Milestone Credits.

                  (f) No Waiver. Nothing in Section 6.4(d) or (e) shall be
construed as a waiver or cure of any breach of any warranties set forth in
Section 7, or any release of any claim by Ciba as may be appropriate relating
thereto.

                  6.5 General Provisions Regarding Royalties.

                  (a) Payments. For purposes of determining the applicable
royalty amounts to be paid pursuant to Section 6.4, Net Sales shall be converted
from the currency used in each country of sale to Swiss Francs and then to
United States Dollars, all in accordance with Ciba's standard method of currency
conversion. All royalty payments shall be made in United States Dollars.

                  (b) Intra-Company Sales. Sales of any System between or among
Ciba and its Affiliates, licensees and sublicensees shall not be subject to any
royalty hereunder, and in such cases 


                                       35
<PAGE>   40
royalties shall be calculated in accordance with this Agreement upon Net Sales
to an independent third party by Ciba or its Affiliates, licensees and
sublicensees. Ciba shall be responsible for payment of any royalty accrued on
Net Sales of such System to such independent third party through its Affiliates,
licensees or sublicensees. Royalties shall accrue hereunder only once in respect
of the same unit of System.

         (c)      Timing of Royalty Payments; Records.

         (i)      within ninety (90) days after the end of each half-year of the
                  Fiscal Year, Ciba shall pay to Dermion the royalty payment due
                  for that half year, provided, that royalties with respect to
                  the first half-year in which any Product or other System is
                  sold shall not be payable with respect to such Product or
                  System until the royalty payment date for the next succeeding
                  half-year.

         (ii)     Together with each royalty payment, Ciba shall submit to the
                  Dermion a written accounting showing its computation of
                  royalties due under this Agreement for such half-year of the
                  Fiscal Year. Said accounting shall (A) set forth gross sales,
                  Net Sales, the specific deductions used in arriving at Net
                  Sales, and the total royalties due for the half-year in
                  question and (B) be in accordance with Ciba's standard
                  accounting practices.

         (iii)    Ciba shall keep full and accurate books and records setting
                  forth gross sales, Net Sales, the specific deductions used in
                  arriving at Net Sales and the amount of royalties payable to
                  Dermion hereunder for no less than two (2) years after the end
                  of each half-year of the Fiscal Year. Ciba shall permit
                  Dermion, at Dermion's expense, to have such books and records
                  examined by independent certified public accountants retained
                  by Dermion and reasonably acceptable to Ciba, during regular
                  business hours upon reasonable advance notice, but not later
                  than two (2) years following the rendering of any such
                  reports, accounting and payments, and no more often than one
                  (1) time per year. Such independent accountants shall keep
                  confidential any information obtained during such examination
                  and shall report to Dermion only the amounts of royalties
                  which the independent accountant believes to be due and
                  payable hereunder.

all material respects:

                  (a) Organization and Good Standing. Such party is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation and has the corporate power and
authority to engage in the business such party is presently engaged in and to
enter into this Agreement and to perform its obligations hereunder.

                  (b) Authorization; Binding Effect. All corporate action on the
part of such party and such party's officers and directors necessary for the
authorization, execution and delivery of this Agreement and for the performance
of all of such party's obligations hereunder has been taken and this Agreement,
when executed and delivered, shall constitute a valid, legally binding
obligation of such party, enforceable against it in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency and other
similar laws affecting creditors' rights generally or general equitable
principles.

                  (c) Noncontravention. The execution, delivery and performance
by such party of this Agreement do not and will not (i) violate or breach the
certificate of incorporation or bylaws of such party, (ii) violate or conflict
with any Applicable Law, (iii) violate, breach, cause a default under or
otherwise give rise to a right of termination, cancellation or acceleration with
respect to (presently, with the giving of notice or the passage of time) any
material agreement, contract or instrument to which it is a party or by which
any of its assets is bound, or (iv) result in the creation or imposition of any
lien, pledge, mortgage, claim, charge, or encumbrance ("Lien") upon any assets

previously conducted by IOMED and (ii) to perform the transactions contemplated
by this Agreement except, in each case, for the IOMED Technology.

                  (g) Interim Agreement. All amounts paid by Ciba to IOMED prior
to the date hereof pursuant to the Interim Agreement and not previously spent in
accordance therewith have been contributed to Dermion by IOMED pursuant to the
Contribution Agreement.

                  7.2 Representations and Warranties of Ciba. Ciba hereby
represents and warrants to IOMED and Dermion that, as of the date of this
Agreement, the following statements are true and correct in all material
respects:

New York and has the corporate power and authority to engage in the business
Ciba is presently engaged in and to enter into this Agreement and to perform its
obligations hereunder.

                  (b) Authorization; Binding Effect. All corporate action on the
party of Ciba and Ciba's officers and directors necessary for the authorization,

and delivered, will constitute a valid, legally binding obligation of Ciba
enforceable against Ciba in accordance with its terms, except as enforceability
may be limited by bankruptcy, insolvency and other similar laws affecting
creditors' rights generally or by general equitable principles.

                  (c) Noncontravention. The execution, delivery and performance
by Ciba of this Agreement do not and will not (i) violate or breach the
certificate of incorporation or bylaws of Ciba, (ii) violate or conflict with
any Applicable Law, (iii) violate, breach, cause a default under or otherwise
give rise to a right of termination, cancellation or acceleration with respect
to (presently, with the giving of notice or the passage of time) any material

                  (d) Government and Other Consents. No consent, authorization,
license, permit, registration or approval of, or exemption or other action by,
any Governmental Authority or other Person is required in connection with Ciba's
execution and delivery of this Agreement or with the performance by Ciba of its
obligations hereunder; provided, however, that no representation is made with
respect to any consent, authorization, license, permit, registration or approval
that may be required from Governmental Authorities as a precondition to the
First Commercial Sale of any Product in any jurisdiction.

                  (e) Ciba Technology. Ciba is the owner of the Ciba Technology
and has the right to license said Ciba Technology free of any Lien in the manner
set forth in this Agreement; it has not assigned or conveyed any interest in the
Ciba Technology which may be inconsistent with the rights granted hereunder; to
the best of its knowledge, the practice of the Ciba Technology by Ciba in
connection with its business activities does not infringe any rights of third
parties; Ciba is not aware that any third party is infringing the Ciba
Technology; and Ciba has prosecuted all patent applications within the Ciba
Technology in good faith and has no reason to believe that any patent included
within the Ciba Technology would be invalid or would be held to be unenforceable
by a court of competent jurisdiction. To the best of Ciba's knowledge, after
reasonable inquiry, Schedule 1.1(a) sets forth all Patent Rights and
identifiable Know-How owned or licensed by Ciba or its Affiliates applicable to
the development of Systems.

                  7.3 DISCLAIMERS. EXCEPT TO THE EXTENT EXPRESSLY PROVIDED IN
THIS AGREEMENT, THE PARTIES HEREBY EXPRESSLY DISCLAIM ALL WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING (A) ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE, AND (2) THAT ANY PATENT WILL ISSUE BASED UPON ANY PENDING
PATENT APPLICATION INCLUDED WITHIN LICENSED TECHNOLOGY.

                  7.4 LIMITED LIABILITY. NOTWITHSTANDING ANY OTHER PROVISION OF
THIS AGREEMENT OR OTHERWISE, NO PARTY TO THIS AGREEMENT SHALL BE LIABLE WITH
RESPECT TO ANY SUBJECT MATTER OF THIS AGREEMENT UNDER ANY CONTRACT, NEGLIGENCE,
STRICT LIABILITY OR OTHER LEGAL OR EQUITABLE THEORY FOR (A) ANY INCIDENTAL OR
CONSEQUENTIAL DAMAGES OR LOST PROFITS OR (B) COST OF PROCUREMENT OF SUBSTITUTE
GOODS, TECHNOLOGY OR SERVICES.

                         OTHER COVENANTS AND AGREEMENTS

                  8.1      Confidentiality.

                  (a) Confidential Information. "Confidential Information" of
Dermion, IOMED or Ciba shall mean (1) all written information disclosed by such
party hereunder (i) bearing a legend indicating that such information is
confidential and (ii) that does not constitute Confidential Information of any
non-disclosing party pursuant to clause (2), (3) or (4) below, (2) all
intellectual property of such party that is disclosed or furnished by such party
hereunder (including, without limitation, in the case of Ciba, all Ciba
Technology, in the case of Dermion, all Dermion Technology, and, in the case of
IOMED, all IOMED Technology), (3) Improvements specific to the Licensed
Technology of such party made in the course of the Program and (4) any results
of the Program that are specific to the Licensed Technology of such party.

                  (b) Nondisclosure. During the term of this Agreement and for a
period of ten (10) years thereafter, except as expressly authorized by the other
party in writing, each of Dermion, IOMED and Ciba agrees to use diligent
efforts, and at least the same degree of care that it uses to protect its own
confidential information of like importance, to prevent unauthorized use,
dissemination and disclosure of any other party's Confidential Information. In
furtherance, and not in limitation of the foregoing, each of Dermion, IOMED and
Ciba agrees that, except as otherwise permitted hereunder, it shall (1) use such
confidential Information exclusively for the purpose of exercising its rights
and fulfilling its obligations under this Agreement, (2) restrict disclosure of
such Confidential Information to those of its employees, agents, collaborative
partners and Affiliates who have a "need to know" such information, and refrain
from disclosing such Confidential Information to anyone other than such
employees, agents, collaborative partners and Affiliates, and (3) cause each of
its Scientists to agree in writing to, and instruct all other such employees,
agents, collaborative partners and Affiliates, to maintain the confidentiality
of such information and not to use such Confidential Information except as
expressly permitted herein.

                  (c) Exceptions. The provisions contained in Section 8 (b)
above shall not apply to any portion of the Confidential Information of any
party which: (1) becomes a matter of public knowledge through no fault of the
party receiving the Confidential Information, (2) is rightfully 


                                       41
<PAGE>   46
received by the receiving party from a third party, (3) was known to the
receiving party before its first receipt from the disclosing party, as shown by
files existing at the time of initial disclosure, or (4) is independently
developed by the receiving party without use of another party's Confidential
Information.

                  (d) Return of Information. After any termination of this
Agreement, upon written request, each party shall promptly discontinue the use
of, and return all originals and copies of, any requested Confidential
Information that has been fixed in any tangible means of expression within
thirty (30) days of such request; provided, however, that if a party's license
rights pursuant to Article 5 shall remain in effect notwithstanding such
termination, such party shall be permitted to retain such information concerning
Licensed Technology as is necessary, in its reasonable judgment, in connection
with the continued exercise of its license rights hereunder. In the event that
information concerning Licensed Technology is retained after termination
pursuant to the preceding sentence, the retaining party shall, upon the request
of the party to which such information relates or belongs (as used in this
paragraph (d), the "other party"), within ninety (90) days after termination,
provide the other party with a written description, in reasonable detail, of the
information concerning the other party's Licensed Technology that has been
retained.

                  (e) Court or Administrative Order. In the event that Dermion,
IOMED or Ciba is requested or required pursuant to Applicable Law by any
Governmental Authority to disclose any Confidential Information, such party
shall provide the party whose Confidential Information is the subject of the
request or requirement (as used in this paragraph (e), the "other party") with
prompt written notice of such request or requirement so that the other party may
seek a protective order or other appropriate remedy or waive compliance with the
provisions of this Agreement. If, in the absence of a protective order or other
remedy or the receipt of a waiver by the other party, the party being requested
or required to disclose any Confidential Information is nonetheless legally
compelled to disclose such Confidential Information, it may, without liability
hereunder, disclose only that portion of the Confidential Information which it
is legally compelled to disclose.

                  8.2      IOMED Covenant Not to Compete.

                  (a) Covenant. IOMED agrees that during the term of this
Agreement neither it nor any of its subsidiaries, other than Dermion, shall
engage, directly or indirectly, in the Restricted Business. For purposes of this
Section 8.2 the term "Restricted 


                                       42
<PAGE>   47
Business" shall mean the business of conducting research with respect to or
developing Systems on its own behalf and/or on behalf of third parties (other
than such research or development by IOMED on its own behalf and not for a third
party with respect to Systems for Drugs used in the treatment of acute
inflammation or for inducement of local anesthesia).

                  (b) Blue Penciling. The parties agree and acknowledge that the
duration, scope and geographic area of the covenant not to compete described in
this Agreement are fair, reasonable and necessary in order to protect the
legitimate interests of Ciba, and that adequate consideration has been received
by IOMED for such obligations. If, however, for any reason any court determines
that the restrictions in this Agreement are not reasonable or that such
consideration is inadequate, such restrictions shall be interpreted, modified or
rewritten to include as much of the duration, scope and geographic area
identified in this Agreement as will render such restrictions valid and
enforceable.

                  (c) Injunctive Relief. The parties acknowledge that any breach
of the provisions contained in this Section 8.2 will result in serious and
irreparable injury to Ciba. Therefore, IOMED acknowledges and agrees that in the
event of a breach of such provisions, Ciba shall be entitled, in addition to any
other remedy at law or in equity to which Ciba may be entitled, to equitable
relief against IOMED, including, without limitation, an injunction to restrain
IOMED from such breach and to compel compliance with this Section 8.2 in
protecting or enforcing the rights and remedies of Ciba hereunder.

                  (d) No Other Limitation. Except only as provided in Section
8.2(a) above, nothing contained in this Agreement or any other document executed
in connection herewith shall be construed as limiting in any manner the free and
unrestricted ability of IOMED to carry on its business activities in any manner
that it chooses in its sole and absolute discretion.

                  8.3 Change of Control of Dermion.

                  (a) Covenant Against a Change of Control of Dermion. For a
period of two (2) years from the date of this Agreement, Dermion covenants and
agrees that, without the prior written consent of Ciba, it shall not cause or
approve a Change of Control of Dermion.

                  (b) Injunctive Relief. The parties acknowledge that any breach
of the provisions contained in this Section 8.3 will result in serious and
irreparable injury to Ciba. Therefore, Dermion acknowledges and agrees that in
the event of a breach of 


                                       43
<PAGE>   48
this Agreement, Ciba shall be entitled, in addition to any other remedy at law
or in equity to which Ciba may be entitled, to equitable relief against Dermion,
including, without limitation, an injunction to restrain Dermion from such
breach and to compel compliance with this Agreement in protecting or enforcing
the rights and remedies of Ciba hereunder.

                  8.4 Right of First Offer.

                  (a) Offer. If at any time the Board of Directors of Dermion
proposes to enter into or approve a transaction or series of related
transactions which, if consummated, would result in a Change of Control of
Dermion (a "Transaction"), then it shall promptly forward to Ciba a written
notice (an "Offer Notice") offering to enter into a Transaction with Ciba and
specifying the purchase price (the "Proposed Purchase Price") and other terms
and conditions under which it would enter into such Transaction with Ciba (the
offer made in any such Offer Notice, the "Offer"). Ciba shall have sixty (60)
days after its receipt of an Offer Notice (the "Acceptance Period") to provide
written notice to Dermion of its acceptance of the offer.

                  (b) Response to Offer. If Ciba accepts the offer, it shall be
obligated to consummate such Transaction at the price and other terms specified
in the Offer Notice within one hundred twenty (120) days after the acceptance of
the Offer, subject to negotiation of a definitive acquisition agreement
containing representations and warranties, covenants, conditions to closing and
such other terms and conditions customary for agreements of its type. If Ciba
rejects the Offer (or otherwise fails to forward an acceptance of the offer
prior to the expiration of the Acceptance Period), Dermion shall, for a period
of two hundred seventy (270) days after expiration of the Acceptance Period,
have the right to consummate a Transaction of the type described in the Offer
Notice only at a price greater than ninety percent (90%) of the Proposed
Purchase Price and on such other terms and conditions more favorable to it than
those offered to Ciba (unless Ciba consents to such lower price or other terms
and conditions, which consent shall not be unreasonably withheld, it being
understood that Ciba's withholding of consent based on its desire to consummate
a Transaction at such lower price or other terms and conditions shall be deemed
reasonable); provided, however, that in the event that a Transaction has not
been consummated within such two hundred seventy (270) day period, then any
proposed future Transaction shall continue to be subject to this Section 8.4.

                  (c) Survival. The offer rights of Ciba described in this
Section 8.4 shall survive any termination of this Agreement 


                                       44
<PAGE>   49
for a period of twelve (12) months from the effective date of such termination.

                              TERM AND TERMINATION

                  9.1 Term. Unless terminated sooner pursuant to Section 9.2,
this Agreement shall continue in full force and effect from the date hereof
through and including December 31, 1997, and shall automatically be renewed for
subsequent one (1) year periods indefinitely.

                  9.2 Termination. This Agreement may be terminated by the
parties as follows:

                      (i)  by either Dermion or Ciba, effective as of the
                           expiration of the initial term or any extension
                           thereof, for any reason or no reason by written
                           notice to the other given at least six (6) months
                           prior to the expiration of the initial term or any
                           extension thereof;

                      (ii) by mutual agreement in writing signed by Dermion and
                           Ciba, effective at the time specified in such
                           writing;

                      (iii) by Dermion upon thirty (30) days, prior written
                           notice to Ciba in the event of a material breach of
                           this Agreement by Ciba which remains unremedied at
                           the end of such thirty (30) day period, or by Ciba
                           upon thirty (30) days, prior written notice to
                           Dermion in the event of a material breach of this

                           unremedied at the end of such thirty (30) day period,
                           effective, in either case, at the end of such thirty
                           (30) day period;

                      (iv) by Dermion in the event of a Bankruptcy Event of
                           Ciba, or by Ciba in the event of a Bankruptcy Event
                           of Dermion, in either case, effective immediately;

                           Change of Control of Dermion (other than a Change of
                           Control resulting from a Transfer that is not a
                           Prohibited Transfer) upon 


                                       45
<PAGE>   50
                           thirty (30) days' prior written notice to Dermion,
                           effective at the end of such thirty (30) day period,
                           provided, that Ciba must exercise such right not
                           later than ninety (90) days after receiving written
                           notice from Dermion of such transaction; and

                      (vi) by Ciba, effective immediately, in the event that for
                           any reason any Key Employee is terminated or resigns
                           as a Program Employee (or is otherwise unable for a
                           period of three (3) months to perform his obligations
                           as a Program Employee in substantially the same
                           manner as previously performed (a "Disability")) and
                           such Key Employee is not replaced with an individual
                           with comparable qualifications and acceptable to Ciba
                           in its reasonable discretion within three (3) months
                           of such termination, resignation or Disability.

Any termination of this Agreement effected pursuant to this Section 9.2 shall be
effective with respect to and binding on all parties to this Agreement.

                  9.3 Survival Upon Termination. The parties agree that their
respective rights and obligations pursuant to Sections 2.4(f), 2.5(e), 3.1-3.3
(to the extent of the Exclusivity Period), 4.1-4.4, 4.6, 4.7, 5.1, 5.3(b), 5.4,
5.5, 6.3-6.6, 7.4, 8.1, 8.3, 8.4, 9.3-9.5, 9.6, 9.7, 9.8, 10.1, 10.2, 11.1 and
11.10 shall survive termination of this Agreement for any reason, and a
non-breaching party shall have the right to seek monetary or injunctive relief
upon any material breach by the other party of such provisions, provided that
such rights and obligations shall in any event terminate on the tenth (l0th)
anniversary of the effective date of termination of this Agreement.

                  9.4 Continuing Liability. Termination of this Agreement for
any reason shall not release any party from any liability, obligation or
agreement which has already accrued nor affect the survival of any provision
hereof which is expressly stated to survive such termination. Termination of
this Agreement for any reason shall not constitute a waiver or release of, or
otherwise be deemed to prejudice or adversely affect, any rights, remedies or
claims, whether for damages or otherwise, which a party may have hereunder or
which may arise out of or in connection with such termination.


                                       46
<PAGE>   51
                  9.5 Partial Termination. Ciba shall have the right to
terminate this Agreement in part and thereafter continue the Agreement based on
a reduced number of full-time equivalent employees serving as Program Employees
(a "Partial Termination") any such Partial Termination to be effective no
earlier than December 31, 1997 or, if this Agreement is extended in accordance
with Section 9.1, the last day of such extension. In order to exercise such
right, Ciba shall give Dermion notice of such Partial Termination at least three
(3) months prior to the expiration of the initial term or any extension thereof,
such notice to indicate the number and function of the full-time equivalent
employees with respect to which Ciba intends to continue the Agreement. In such
event, this Agreement shall continue in full force and effect in all respects,
with the only modifications as a result of such Partial Termination being the
reduction in full-time equivalent employees serving as Program Employees and
reductions in Research Funding Payments payable by Ciba, and facilities and
other resources to be provided by Dermion. A Partial Termination shall not
constitute a termination of this Agreement for any other purpose.

                  9.6 Rejection in Bankruptcy. In receipt of good and valuable
consideration, which is hereby acknowledged, Dermion hereby grants to Ciba a
security interest in and to the Dermion Technology to secure performance of any
and all obligations of Dermion set out in this Agreement and agrees to execute
and assist Ciba in filing such Form UCC-l's and other documents as may be needed
from time to time to perfect such security interest. A rejection of this
Agreement by a trustee in bankruptcy or debtor in possession shall be a default
under this Agreement, whereupon Ciba shall have all rights and remedies of a
secured party under the Uniform Commercial Code.

                  9.7 Program Records.

                  (a) Retention of Program Records. All Program Records shall be
retained by any party in possession thereof for a period of seven (7) years
following termination of this Agreement (the "Document Retention Period").
During the Document Retention Period, neither Dermion nor Ciba (or their
respective Affiliates) shall destroy or give up possession of any Program
Records without first offering to the other the opportunity to obtain the same.
In such event, such other party shall be responsible for costs of delivery, if
any. Thereafter, the party wishing to dispose of such Program Records shall be
free to do so as it deems fit.

                  (b) Access to Program Records. During the Document Retention
Period all Program Records that are retained by any party shall be open for
inspection by representatives of the 


                                       47
<PAGE>   52
other party at any time upon reasonable notice during regular business hours
until such time as such documents are disposed of in accordance with Section
9.7(a), and during such period a party may at its expense make such copies
thereof as it may reasonably request.

                  9.8 Certain Actions Following Termination. If, following the
effective date of any termination of this Agreement, any action or decision is
required to be taken or made by the Committee under the terms hereof, any such
action or decision shall be taken or made by mutual agreement of Ciba and
Dermion provided, that Ciba will continue to have a veto over Ciba Matters.

                  10.1 Indemnification by Dermion and IOMED. Dermion and IOMED
shall jointly and severally indemnify and hold harmless Ciba and its directors,
officers, employees and agents and their respective successors, heirs and
assigns, against any liability, damage, loss or expense (including reasonable
attorneys' fees and expenses) arising from or in connection with (i) any
inaccuracy in or breach of any of the representations and warranties of Dermion
or IOMED in this Agreement, (ii) any failure by Dermion or IOMED to perform or
comply with any covenant or agreement in this Agreement, and (iii) the acts or
omissions of Dermion or IOMED in performing its obligations under this
Agreement.

                  10.2 Indemnification by Ciba. Ciba shall indemnify and hold
harmless Dermion and IOMED and their respective directors, officers, employees
and agents and such Persons, respective successors, heirs and assigns, against
any liability, damage, loss or expense (including reasonable attorneys' fees and
expenses) arising from or in connection with (i) any inaccuracy in or breach of
any of the representations and warranties of Ciba in this Agreement, (ii) any
failure by Ciba to perform or comply with any covenant or agreement in this
Agreement, and (iii) the acts or omissions of Ciba in performing its obligations
under this Agreement.

                                  MISCELLANEOUS

                  11.1 Arbitration. Any controversy, claim or dispute between
the parties, directly or indirectly, concerning this 


                                       48
<PAGE>   53
Agreement or the breach hereof or the subject matter hereof, including questions
concerning the scope and applicability of this arbitration clause, shall be
finally settled by three (3) arbitrators knowledgeable in the subject matter
involved in such controversy or claim appointed and acting in accordance with
the then-prevailing commercial arbitration rules of the American Arbitration
Association. One (1) arbitrator shall be selected by each of Ciba and Dermion,
and the third arbitrator shall be selected by mutual agreement of the first two.
The arbitration shall be conducted in New York, NY. The arbitrators shall be
informed that time is of the essence in deciding the matters subject to their
review. The decision in writing of any two of the arbitrators shall be final,
binding and conclusive on each party to this Agreement; judgment upon such
decision or award may be entered in any court of competent jurisdiction; and the
application may be made to such court for confirmation of such decision or
award, for an order of enforcement and for any other legal remedies that may be
necessary to effectuate such decision or award. The arbitrators shall have the
right and authority to assess the costs of the arbitration proceedings.

                  11.2 Publicity. Except after consultation with the other
parties, no party shall publicize, advertise, announce or publicly describe to
any Governmental Authority or other Person, the terms of this Agreement, the
parties hereto or the transactions contemplated hereby, except as required by
Applicable Law or as required pursuant to this Agreement. In the event that
Dermion or IOMED on the one hand or Ciba on the other is requested or required
pursuant to Applicable Law by any Governmental Authority to disclose to any
Governmental Authority or other Person any terms of this Agreement, the party
subject to such request or requirement shall provide the other with prompt
written notice of such request or requirement so that the other party may seek a
protective order or other appropriate remedy or waive compliance with the
provisions of this Agreement. If, in the absence of a protective order or other
remedy or the receipt of a waiver by the other party, the party being requested
or required to disclose such terms of this Agreement is nonetheless legally
compelled to disclose such terms, it may, without liability hereunder, disclose
only that portion of this Agreement which it is legally compelled to disclose.

                  11.3 Assignment. This Agreement shall inure to the benefit of,
and shall be binding upon, the parties and their respective successors and
permitted assigns. No party may assign or delegate this Agreement or any of its
rights or duties under this Agreement without the prior written consent of the
other parties except (i) to an Affiliate of such party who expressly assumes the
obligations of the assigning party hereunder (including, without limitation, by
operation of law), (ii) in the 


                                       49

or to such other person or address as any party may designate in writing from

                  11.7 Force Majeure. If the performance of this Agreement or
any obligations hereunder is prevented, restricted or interfered with by reason
of fire or other casualty or due to strikes, riot, storms, explosions, acts of
God, war, or a similar occurrence or condition beyond the reasonable control of
the parties, the party so affected shall, upon giving prompt notice to the other
parties, be excused from such performance during such prevention, restriction or
interference, and any failure or delay resulting therefrom shall not be
considered a breach of this Agreement.

                  11.8 Disclaimer of Agency. This Agreement shall not be
construed to constitute the parties as partners, joint venturers, agents or
otherwise as participants in a joint or common undertaking. No party (or its
agents and employees) is the representative of the other party for any purpose
and no party has power or authority as agent, legal representative, employee or
in any other capacity to represent, act for, bind, or otherwise create or assume
any obligation on behalf of, any other party for any purpose whatsoever.

                  11.9 Further Assurances. The parties shall each perform such
acts, execute and deliver such instruments and documents, and do all such other
things as may be reasonably necessary to accomplish the transactions
contemplated in this Agreement.

                  11.10 Expenses. The parties shall each bear their own costs
and expenses (including attorneys' fees) incurred in connection with the
negotiation and preparation of this Agreement and, except as otherwise provided
herein, consummation of the transactions contemplated hereby, provided, however,
that all such costs and expenses incurred by IOMED and Dermion shall be borne by
Dermion.

                  11.11 Governing Law. This Agreement shall be governed by, and
construed in accordance with, the laws of New York, without giving effect to the
conflicts of laws provisions thereof.

                  11.12 Entire Agreement. This Agreement, including the exhibits
and schedules hereto, each of which is incorporated herein by this reference,
contains the entire agreement and understanding of the parties, and supersedes
any prior understandings and agreements, with respect to its subject matter,
including the Interim Agreement.

                  11.13 Severability. If any provision of this Agreement, or the
application thereof to any Person, place or circumstance, shall be held by a
court of competent jurisdiction to be invalid, unenforceable or void, the
remainder of this Agreement and such provisions as applied to other Persons,
places and circumstances shall remain in full force and effect only if, after
excluding the portion deemed to be unenforceable, the remaining terms shall
provide for the consummation of the transactions contemplated hereby in
substantially the same manner as originally set forth herein. In such event, the
parties shall negotiate, in good faith, a substitute, valid and enforceable
provision or agreement which most nearly effects the parties' intent in entering
into this Agreement.

                  11.14 Broker's Fees. Each of the parties represents and
warrants that it has not dealt with any broker or finder in connection with any
of the transactions contemplated by this Agreement, and, to its knowledge, no
broker or other Person is entitled to any commission or finder's fee in
connection with any of these transactions. Each of the parties shall be
responsible for, and shall indemnify and hold the other parties harmless
against, the fees of its investment bankers and other advisors, if any.

                  11.15 Article and Section Headings. The article and Section
headings included in this Agreement are for convenience of the parties only and
shall not affect the construction or interpretation of this Agreement.

                  11.16 Counterparts. This Agreement may be executed in any
number of counterparts each of which shall constitute an original instrument but

shares of Common Stock issued upon conversion from and as of such time. Except
as provided in Sections 3.03 and 3.04 hereof, from and after the time of such
conversion, Fournier shall have no further rights, and Iomed shall have no
further obligations, pursuant to the Note.

                  3.02.  Effect of Conversion. Conversion of the Note shall
not constitute a waiver or release of, or otherwise be deemed to prejudice or
affect in any way, a breach by Iomed of any representation or warranty made
pursuant to Section 2.01 hereof. In the event of such breach by Iomed, Fournier
shall have the right to seek monetary and/or injunctive relief.

                  3.03.  Reservation of Conversion Shares. Iomed shall, at all
times during the Conversion Period, reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of
effecting the issuance of Additional Conversion Shares, such number of its
shares of Common Stock as shall be sufficient to effect the issuance of such
Additional Conversion Shares. If, at any time, the number of authorized but
unissued shares of Common Stock is not sufficient to effect the issuance of
Additional Conversion Shares, then Iomed shall immediately take such corporate
action as is necessary to increase its authorized but unissued shares of Common
Stock to such number of shares of Common Stock as shall be sufficient for such
purpose. In the event that Iomed fails to take such corporate action in order to
permit Fournier to receive the Additional Conversion Shares in accordance with
Section 3.04 hereof, (a) such failure shall not affect or otherwise prejudice
Fournier's to such Additional Conversion Shares, and (b) Fournier shall have the
right to (i) receive such Additional Conversion Shares as soon as practicable
after Iomed takes such corporate action and/or (ii) seek other monetary or
injunctive relief.

                  3.04.  Adjustments. Anything herein to the contrary
notwithstanding, during the Conversion Period the substantive effect of the
adjustment provisions set forth in Section 3.2 et seq. of the Note shall
survive, shall be made a part of this Agreement, and shall apply in all respects
as if set forth in full herein so as to effect an adjustment of the number of
Conversion Shares and/or of the Conversion Price in the same manner and to the
same extent, but to no greater extent, as if the Note had not been converted on
the date hereof; provided, however, that the initial Conversion Price shall be
$1.85. It is the intention of the Parties that during the Conversion Period the
adjustment provisions of the Note shall continue to inure to the benefit of
Fournier, subject to the foregoing proviso. If Iomed takes any action during the
Conversion Period that would have the effect of reducing the Conversion Price,
then Fournier shall be entitled to receive Additional Conversion Shares from
Iomed, and Iomed shall deliver to Fournier a certificate for the applicable
number of Additional Conversion Shares.

                ARTICLE V. MEETINGS OF IOMED'S BOARD OF DIRECTORS


                  5.01.    Meetings.

this Agreement, Iomed shall deliver to Fournier a schedule of the date(s) of
each previously scheduled meeting of Iomed's board of directors. In addition,
Iomed shall (1) with respect to each meeting of Iomed's board of directors,

such meeting and any change in such date, time, place, or purpose thereof, (ii)
timely provide to Fournier (subject to Section 5.02 hereof) such other
information and documents that are given to members of Iomed's board of
directors (including, without limitation, minutes of board meetings), and (iii)
permit (subject to Section 5.02 hereof) a representative of Fournier to attend
each such meeting. Any written or other information obtained by Fournier

<PAGE>   14
                           (b) Fournier may elect not to exercise its right to
have its representative attend any such meeting of Iomed's board of directors,
but any such election shall not prejudice or otherwise preclude Fournier's right
to have its representative attend any other meeting (subject to Section 5.02
hereof) nor cause Iomed to fail to provide the notice and other information and
documents required to be furnished to Fournier pursuant to Section 5.01(a)
hereof.

                  5.02.  Limitation. The rights of Fournier pursuant to
Section 5.01 hereof shall terminate automatically upon the earlier of (a) the
date on which Iomed becomes subject to the reporting requirements of Section
13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, or (b) the
date on which Fournier ceases to own, in the aggregate, less than 692,551 shares
of Common Stock or such other stock or securities of Iomed (as adjusted for
stock. splits, combinations and the like). Fournier's right to have its
representative attend meetings of Iomed's board of directors and to receive
information and documents pursuant to Section 5.01 hereof shall not apply if and
to the extent that Fournier is a competitor as of such time with respect to a
business venture in which Iomed, either by itself or in conjunction with any
Person, is engaged or proposes to engage, and such business venture is a subject
of such meeting, in which case Iomed may, acting in good faith and upon written
notice to Fournier, exclude Fournier's representative from that portion of the
meeting and not provide such information and documents related to such portion
of the meeting. It is understood and agreed by the Parties that, if Iomed
intends to exercise its right to exclude Fournier's representative from any
portion of a meeting pursuant to this Section 5.02, Iomed shall notify Fournier
of such intent at the same time it delivers the written notice of such meeting
pursuant to Section 5.01 hereof (or, if the decision to exclude Fournier's
representative is made after the written notice of the meeting is delivered,
then immediately upon becoming aware that any such matter will be discussed at
such meeting, so long as the notice of such intent is received by Fournier not
less than three (3) days prior to the date of such meeting). Iomed shall provide
sufficient information, consistent with the purpose of this Section 5.02 that
competitively sensitive information not be disclosed, to establish that Fournier
is a competitor as of such time with respect to a business venture in which
Iomed, either by itself or in conjunction with any Person, is engaged or
proposes to engage. Fournier shall have the right to challenge the basis for any
exclusion from a meeting.

                  5.03.  Definition. As used in this Article V, the defined
term "Iomed" shall include any Qualifying Affiliate, but not any other Affiliate
of Iomed.

Sealed Bid is greater than, or not more than One Hundred Fifty Thousand Dollars
($150,000 U.S.) less than, the Iomed Sealed Bid, then Iomed shall be obligated

period of one (1) year from the expiration of the respective Offer Period, be
free to sell the Offered Assets (i) at a price not less than the Floor Price
determined by the Escrow Agent in accordance with this Section 7.02, in the
event that the Fournier Sealed Bid is less than the Iomed Sealed Bid by more
than One Hundred Fifty Thousand Dollars ($150,000 U.S.) or (ii) at any price, in
the 


                                       16
<PAGE>   20

(1)-year period shall become subject again to this Section 7.02.

                           (e) Limitations.

                                    (i) The provisions of this Section 7.02

(A) to any Affiliate of Iomed (other than an Affiliate formed or otherwise
created by Iomed and Ciba) or (B) that occurs at a time when Iomed is subject to
the reporting requirements of Sections 13(a) or 15(d) of the Securities Exchange
Act of 1934, as amended. It is understood and agreed by the Parties treat it
shall be a condition precedent to any sale, conveyance or other transfer
pursuant to clause (A) above that the transferee Affiliate agree in writing to
be bound by a right of first offer in favor of Fournier identical to this
Section 7.02 with respect to any subsequent sale, conveyance or other transfer
by such transferee Affiliate of the Iomed Assets transferred to it pursuant to
such clause (A).

                                    (ii) If Iomed or any of its Affiliates
enters into an agreement, joint venture or other collaboration with Ciba for the
research, development, manufacture, marketing, distribution or sale of any
Mini-Integrated System or other product, and such agreement, joint venture or
other collaboration continues in force and effect for a term of not less than
one (1) year, then the provisions of this Section 7.02 shall terminate
automatically upon the expiration of the first year of such agreement, joint
venture or other collaboration, and without any further action by either Party.
It is understood and agreed by the Parties that any such agreement, joint
venture or other collaboration with Ciba shall be subject to the same
restrictions and other limitations imposed upon Iomed pursuant to Articles VI
and VII hereof.

                                    (iii) The rights described in this Section
7.02 shall survive termination of this Agreement.

                           (f) Definitions. As used in this Section 7.02, (i)
the phrase "sell, convey or otherwise transfer," as used in relation to the
specified Iomed Assets, shall mean a sale, conveyance or other transfer of all
of the transferring Party's right, title and interest in and to such Iomed
Assets, and (ii) the defined term "Iomed" shall not include any Affiliate of
Iomed.

                  8.01.  Term. This Agreement shall become effective on the

9.10, and 9.12 of this Agreement; and

                           (f) any right, remedy, claim, action or cause of
action a Party has or may have against the other Party for breach of a material
obligation under this Agreement.

                  8.03.  Continuing Liability. Termination of this Agreement
for any reason shall not release a Party from any liability, obligation,
agreement or other responsibility under this Agreement that already has accrued
or arisen, nor shall any termination constitute a waiver or release of, or
otherwise be deemed to prejudice or affect, any rights, remedies, claims,
actions or causes of action, whether for damages or otherwise, that a Party may
have hereunder or which may arise out of or in connection with such termination.



                         ARTICLE IX. GENERAL PROVISIONS


                  9.01.  Amendments. Neither this Agreement nor any of the
terms hereof may be amended, supplemented, waived or modified except by an
instrument in writing signed by the Party against whom enforcement of such
change is sought.

                  9.02.  Severability of Provisions. Any provision of this
Agreement that may be finally determined by a Governmental Authority to be
invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability, without
invalidating or rendering unenforceable any remaining provisions hereof, and any
such invalidity or unenforceability in any jurisdiction shall not invalidate or


                                       18
<PAGE>   22
render unenforceable such provision in any other jurisdiction. The Parties shall
negotiate in good faith to replace any such provision with an appropriate, legal
provision and, to the extent permitted by law, hereby waive any provision of law
that renders any provision hereof invalid or unenforceable in any respect.

                  9.03.  Governing Law. This Agreement and all issues arising

construction, interpretation, breach, and damages for breach, shall be governed

principles). Any action, cause of action or dispute arising under or relating to
this Agreement shall be brought only in the courts of the State of New York or
the federal court of the United States, located in the Borough of Manhattan,
County of New York, the State of New York, and each of the Parties expressly
consents-to personal jurisdiction in the State of New York with respect to such
action, cause of action or dispute.

                  9.04.  Headings. The division of this Agreement into
sections, the provision of a table of contents, and the insertion of headings
are for convenience of reference only and shall not affect the construction or
interpretation of this Agreement.

                  9.05.  Counterparts. This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original but all of
which taken together shall constitute one and the same instrument.

All such communications and notices given in such manner shall be deemed given

                  9.07.  Specific Performance. Each Party hereto acknowledges
that the payment of monetary damages may be an inadequate remedy for the breach
of its obligations under this Agreement, and agrees that the other Party shall
be entitled to specific performance of such obligations.

                  9.08.  Successors and Assigns. This Agreement, including the
terms and provisions hereof, shall be binding upon, and inure to the benefit of,
each of Iomed and Fournier and their respective successors and permitted
assigns.
                  9.09.  Further Assurances. Each of the Parties shall perform
such acts, execute and deliver such instruments and documents, and do all such
other things as may be reasonably necessary to accomplish the transactions
contemplated under this Agreement.

                  9.10.  Expenses. Each of the Parties shall bear its
respective costs and expenses (including attorneys' fees and expenses) incurred
in connection with the negotiation and preparation of this Agreement and
consummation of the transactions contemplated hereby. In any action, cause of
action or dispute arising under or relating to this Agreement, a court shall
have the right and authority to assess the costs of the proceedings.

                  9.11.  Assignment. Except as expressly provided to the
contrary in this Agreement, neither Party may assign any of its rights or
obligations under this Agreement without the prior written consent of the other
Party, which consent shall not be unreasonably withheld. Notwithstanding the
foregoing, it is understood and agreed by the Parties that each Party may assign
its rights and obligations under this Agreement in conjunction with the
incorporation of any unit of such Party as a wholly owned Affiliate and, in the
case of Fournier, the disposition of any of its units, including, without
limitation, Tilderm Systems; 


                                       20
<PAGE>   24
provided, however, that Fournier shall not be permitted to assign its rights
under Article V or Section 7.02 hereof to any Person other than an Affiliate of
Fournier.

                  9.12.      Confidential Information.

                           (a) Confidentiality. A Receiving Party agrees that it
shall, and that it shall use diligent efforts to ensure that each of its
officers, directors, employees and agents shall, protect and hold in confidence
all Confidential Information of the Disclosing Party and shall not disclose, or
cause to be disclosed, such information to third parties, except as expressly
provided to the contrary in this Agreement. In furtherance, and not in
limitation, of the foregoing, each Party agrees that it shall (i) leave in place
any proprietary or confidential legends or markings placed upon any Confidential
Information by the Disclosing Party, (ii) restrict disclosure of Confidential
Information to those of its officers, directors, employees and agents who have a
"need to know" in respect to such information, and (iii) instruct and require
such officers, directors, employees and agents to maintain the confidentiality
of Confidential Information and not to use such information except as expressly
permitted herein. Such obligations shall apply with respect to Confidential
Information for the term of this Agreement and for a period of ten (10) years
after any termination of this Agreement.

                           (b) Rights to Confidential Information. All
Confidential Information shall remain the sole property of the Disclosing Party,
and the Receiving Party shall have no rights or interests (except as hereinafter
provided) to or in such information.

                           (c) Return of Confidential Information. Immediately
upon any termination of this Agreement, each Party shall discontinue the use of
Confidential Information of the other Party, and the Receiving Party shall, upon
the written request of the Disclosing Party, return to such Party, within thirty
(30) days of such request, all items of Confidential Information of such Party,
including, without limitation, all copies and originals of such items of
Confidential Information, that are identified specifically in such written
request; provided, however, that, if and to the extent that any license or
sublicense granted pursuant to Section 6.02, 6.03 or 6.04 hereof shall remain in
effect notwithstanding such termination, a Receiving Party shall be permitted to
retain only such Confidential Information as is reasonably necessary for the
continued exercise of its license or sublicense rights hereunder and to use such
Confidential Information within the scope of such license or sublicense.

                           (d) Exceptions. Notwithstanding any other provisions
of this Agreement, nothing obtained by a Receiving Party shall be deemed
Confidential Information of the Disclosing Party if such information: (i) is not
marked or otherwise designated in writing as confidential and is provided for a
purpose that reasonably contemplates disclosure to or use by any other Person,
(ii) becomes a matter of public knowledge through no action or inaction of the
Receiving Party, (iii) is disclosed by the Disclosing Party to a third party
without a duty of confidentiality, (iv) is rightfully received by the Receiving
Party from a third party without a duty of confidentiality, or (v) was known to
the Receiving Party before it first was received from the Disclosing Party, as
shown by files and records of the Receiving Party 


                                       21
<PAGE>   25
existing at the time of initial disclosure. Information shall not be deemed to
be a matter of public knowledge, for the purpose of the exclusion (ii) above
with respect to each Party, merely because it (x) is embraced by more general
information in the prior possession of a Party or any other Person or (y) is
expressed in public literature in general terms not specifically in accordance
with the Confidential Information.

                           (e) Disclosure.

                                    (i) A Receiving Party shall immediately
notify a Disclosing Party of receipt of any process, subpoena or demand by any
Governmental Authority or any other Person, requiring production of Confidential
Information of the Disclosing Party, and shall, within one (1) day after such
receipt, furnish to the Disclosing Party a copy of such process, subpoena or
demand and of all materials and facts relating thereto. The Disclosing Party
shall have the right to take any legal action to prevent disclosure of its
Confidential Information, including, without limitation, the right to appear on
behalf of the Receiving Party, to represent the Receiving Party, and to employ
counsel of its choice for these purposes, all at its expense.

                                    (ii) The Disclosing Party shall have the
right to make any legal arguments and to take any legal action, including,
without limitation, trials and appeals on behalf of itself and the Receiving
Party, to prevent disclosure of its Confidential Information. If a Disclosing
Party elects to exercise its rights under this Section 9.12(e), it shall do so
at its expense and shall protect, hold harmless, defend, and indemnify the
Receiving Party from and against any and all legal responsibility or liability
from the exercise of these rights. If a Disclosing Party elects not to exercise
any such rights or if, in the absence of a protective order or other remedy or
the receipt of a waiver by the Disclosing Party, the Receiving Party is
nonetheless legally compelled to disclose Confidential Information of the
Disclosing Party, then the Receiving Party may, without liability hereunder,
disclose only that portion of such Confidential Information that it is legally
compelled to disclose.

                           (f) Confidentiality of Agreement. The provisions of
this Section 9.12 also shall apply to the contents of this Agreement; provided,
however, that the contents hereof may be disclosed: (i) as required by
Applicable Law; (ii) to accountants, banks, financing sources, lawyers,
consultants, prospective clients, sublicensees, and any Person with whom a Party
has a written contractual collaboration, so long as such recipients keep such
contents confidential; (iii) in connection with the enforcement of this
Agreement; (iv) in connection with a financing, merger, acquisition, public
offering, or proposed financing, merger, acquisition or public offering; or (v)
pursuant to joint press releases prepared in accordance with Section 9.13
hereof.

                           (g) Notification of Breach. Each Party shall notify
the other Party in the event of any breach of this Section 9.12, including,
without limitation, conditions or circumstances that indicate Confidential
Information has been or may have been prejudiced or otherwise exposed to loss or
unauthorized disclosure or use. A Receiving Party shall, upon request of the
Disclosing Party, take all steps reasonably necessary to recover any and all


                                       22
<PAGE>   26
Confidential Information that has been or may have been compromised, prejudiced,
improperly disclosed or otherwise exposed to loss or unauthorized use. The
expense of taking such steps shall be borne solely by the Receiving Party.

                           (h) Equitable Relief. Each Party acknowledges and
agrees that (i) any breach of the obligations under this Agreement, including,
without limitation, the confidentiality provisions under this Section 9.12, is
likely to cause or threaten irreparable harm to the other Party and (ii) in such
event, each Party shall be entitled to equitable relief to protect its
interests, including, without limitation, preliminary and permanent injunctive
relief, as well as money damages.

                  9.13.  Publicity. The Parties shall jointly review, discuss
and agree upon any statement to the public regarding the subject matter of this
Agreement after full consideration of (a) the accuracy of the disclosure, (b)
the requirements for confidentiality under Section 9.12 hereof, (c) the
advantage a competitor of either Party might gain from any public or third-party
statements, (d) disclosure requirements under any Applicable Law (including,
without limitation, securities laws and regulations relating to public
offerings), and (e) the standards and customs in the pharmaceutical industry for
such disclosures by companies comparable to both of the Parties. Notwithstanding
the foregoing, neither of the Parties nor any of their respective officers,
directors, employees, agents or advisors shall publicize, advertise, announce or
describe to any Governmental Authority or any other Person the terms of this
Agreement, either of the Parties, or the transactions contemplated hereby,
except as required by Applicable Law or as required or expressly permitted
pursuant to this Agreement.

                  9.14.  Entire Agreement. This Agreement contains the entire
agreement between the Parties with respect to the subject matter hereof and
supersedes all prior and contemporaneous agreements and understandings, oral and
written, with respect to such 


                                       23
<PAGE>   27
transactions, including, without limitation, Iomed's Letter of Understanding
(along with its attachments) dated October 3, 1995 and each and every provision
of the Research and Development Agreement (including, without limitation, the
provisions of Article 8 thereof).

             IN WITNESS WHEREOF, the Parties have caused this Agreement to be
duly executed as of the date first above written.

     RE: IOMED License Agreement (U-671D)

Dear Ned:

     In accordance with paragraph 11.1 of the revised agreement which we are
currently negotiating, the University and I want to disclose to IOMED that we
are aware of a Sarcos project on a mechanical artificial arm that Dr. Jaocobsen
is involved in.

     It is our understanding that the Department of Veterans Affairs is funding
the project at Sarcos, and although some machining work may be done at the
University, no inventive work will be involved at the University.

     Since this is a mechanical device and a Sarcos project without University
rights involved, paragraph 11.2 should not apply.

     If you have any questions, please don't hesitate to call.



                                        Yours truly,



                                        /s/ TOM MAJOR
