                                  THE COMPANY
 
     UroSurge develops, manufactures and markets medical devices for the
treatment and management of genito-urinary disorders. The Company is developing
a broad range of proprietary products to address segments of the urology market
that are currently underserved as a result of ineffective or costly therapies.
The Company is initially focusing much of its efforts on addressing urinary
incontinence ("UI"), which afflicts approximately 13 million people in the U.S.
and accounts for approximately $15 billion in annual treatment costs. The UI
market presents a significant opportunity because approximately two-thirds of UI
sufferers are dissatisfied with current treatment alternatives according to a
recent U.S. study by the National Association for Continence. The Company
believes that its lead products, UroVive for stress UI and the Stoller Afferent
Nerve Stimulation ("SANS") devices for urge UI, represent superior alternatives
to existing therapies by offering minimally invasive, cost-effective, long-term
solutions for patients suffering from these conditions. The Company launched
these products in Europe in March 1998 and is currently conducting pivotal
(late-stage) clinical trials in the U.S. Additionally, the Company is developing
and marketing a number of other products to treat a variety of urological
conditions.
 
     UroVive is a minimally invasive urethral bulking system for the treatment
of certain types of stress UI. The UroVive procedure involves the permanent
implantation of one or more hydrogel-filled microballoons around the urethra and
is designed to close the bladder neck and immediately restore urinary
continence. The procedure can be performed in about 20 minutes in an outpatient
setting under local anesthesia. The Company believes that UroVive is a
practical, safe, long-term solution and is more convenient and cost-effective
than palliative approaches such as diapers and urethral plugs that do not cure
the problem. The Company also believes that UroVive offers significant
advantages over competing injectable urethral bulking agents that suffer from
problems of absorption and migration (which can lead to the need for repeat
procedures or raise safety concerns) and are not easily retrievable should
urinary retention occur. UroVive also provides an advantage over invasive
surgical procedures, which are costly and can result in post-surgical
complications. The Company is marketing and selling UroVive in Europe under CE
mark certification, and is currently conducting pivotal clinical trials of
UroVive in the U.S. Results of pilot (early-stage) clinical trials indicate a
90% efficacy rate for patients with the target indication for which the Company
has 18-month follow-up data. By comparison, clinical results of the only
urethral bulking agent sold commercially in the U.S. indicate only a 52%
probability that such patients will maintain their initial continence for one
year. The Company expects to submit a pre-market approval ("PMA") application to
the U.S. Food and Drug Administration ("FDA") for UroVive in mid-1999.
 
     The Company has two SANS devices, percutaneous (through the skin) and
subcutaneous (below the skin), for the treatment of urge UI. Both are minimally
invasive systems that modulate bladder action through stimulation of the
afferent nerve fibers in the ankle area that lead to nerves located in the
spinal region that control bladder function. Such stimulation has been shown to
greatly reduce the likelihood that the patient will have an uncontrollable spasm
of the bladder wall muscle that can cause the bladder to empty. The percutaneous
SANS procedure entails approximately 30 minutes of electrical stimulation and is
repeated
 
                                        3
<PAGE>   5
 
weekly in a physician's office. Percutaneous SANS consists of a generator that
delivers electrical impulses through a small disposable needle, temporarily
inserted near the ankle, and lead wire assembly. To facilitate in-home use and
enhance patient convenience, the Company is developing a second generation,
subcutaneous SANS device that involves the permanent implant of a small,
thumbtack-shaped electronic receiver near the patient's ankle, eliminating the
need for the use of a needle with each treatment. Few products exist for
effectively treating urge UI and the Company believes that SANS is superior to
other commercially available products due primarily to its minimally invasive
nature and cost-effectiveness. Clinical studies to date on percutaneous SANS,
encompassing over 1,000 treatment procedures in 90 patients with average
follow-up in excess of two years, indicate an 80% efficacy rate and no
complications. By comparison, clinical results of the only commercially
available implantable electronic nerve stimulation device also indicate a
comparable efficacy rate, but a high rate of post-treatment complications that
required reoperation in approximately one-third of all cases. This competing
product involves an invasive surgical implant procedure in the spinal area that
is costly and requires extensive physician training. The Company is marketing
and selling percutaneous SANS in Europe and is currently conducting a pivotal
clinical trial in the U.S. The Company expects to submit a PMA application for
acute use of percutaneous SANS by early 1999.
 
     As part of its strategy of offering a broad range of products to physicians
treating genito-urinary disorders, the Company has also developed or licensed
SpiraStent, FilaStent and a kidney stone grasper for use in removing kidney
stones; AcuTrainer for diagnosing and managing urge UI; UroTherm for warming
irrigation fluids used in various gynecological and urological procedures;
demineralized bone paste for use in treating vesicoureteral reflux ("VUR") in
infants and children; and a urethral pressure catheter for the diagnosis of
stress UI. The Company has received FDA 510(k) clearance for U.S. marketing of
SpiraStent and AcuTrainer and has submitted 510(k) clearance applications for
FilaStent and UroTherm. The Company is currently marketing and selling
SpiraStent, FilaStent and AcuTrainer in Europe and SpiraStent and AcuTrainer in
the U.S.
 
                                    STRATEGY
 
     The Company's objective is to establish itself as the leader in the
development and commercialization of clinically effective solutions for UI and
other genito-urinary disorders treated by urologists, urogynecologists and
gynecologists. The following are the key elements of the Company's strategy.
 
     Accelerate Commercialization of Existing Products. The Company has
substantially developed the infrastructure, including international
distributors, manufacturing capabilities and sales and marketing management,
that will help accelerate the commercialization of its products. The Company is
marketing and selling UroVive, percutaneous SANS, SpiraStent, FilaStent and
AcuTrainer in Europe and other international markets and is recognizing revenues
from these efforts in the second quarter of 1998. The Company is also marketing
and selling SpiraStent and AcuTrainer in the U.S. and intends to commence
marketing of UroVive and SANS in the U.S. upon receipt of PMA approval.
 
     Become the Leader in the Treatment of UI. UI is a significant problem for a
large number of adults, particularly women and the elderly, and is one of the
most intractable and debilitating conditions treated by urologists and
urogynecologists. The UI market offers significant potential due primarily to
the inadequacy of existing treatments. The Company intends to offer improved
approaches for all levels of care, ranging from diagnosis to surgery, and for
all types of UI. The Company is focusing on the development of products that are
highly effective and minimally invasive, as compared to many current approaches
for managing UI, which are either palliative, such as diapers, or involve
invasive surgical procedures.
 
     Offer a Comprehensive Product Line. Urologists, urogynecologists and
gynecologists are responsible for treating most genito-urinary disorders and use
a wide range of products. The Company is developing a broad line of products to
address the needs of these physicians while focusing on product opportunities
that represent significant improvements over currently available therapies. As
part of these efforts, the Company intends to explore the applicability of its
current products and technologies to additional clinical indications. The
Company also continually evaluates product concepts and technologies that may
present potential solutions for
 
                                        4
<PAGE>   6
 
unmet needs in its targeted markets and, in addition to internal development
efforts, actively seeks to license or acquire rights to such potential products
and technologies.
 
     Penetrate International Markets. The Company believes that there is a
significant international market for its products. The Company distributes
products internationally through local distributors on a country-by-country
basis to access such distributors' established networks and specialized
expertise regarding the health care system, including reimbursement practices,
in their respective markets. The Company's current distributors cover 14
European countries, South Korea, Australia and Japan. In addition, as part of
its international marketing efforts, the Company has established clinical
research relationships with leading international urologists. The Company
believes that its country-specific approach will accelerate sales growth,
provide comprehensive geographic market coverage and enable the Company to
access particular markets and customers.
 
     Build Specialized, Direct Sales Force in the U.S. According to industry
sources, there are approximately 8,000 urologists and 800 urogynecologists in
the U.S. The Company believes that this relatively small number of physicians to
which it will market its products affords a unique opportunity to develop a
cost-effective, direct sales effort. Accordingly, the Company has retained all
U.S. sales and marketing rights to its products and has commenced hiring of a
marketing and sales force in the U.S. To gain acceptance of its products, the
Company conducts physician training and disseminates clinical and patient
outcome data. In addition, the Company markets its products by raising patient
awareness of its available treatments through advertising, magazine articles and
other media.
 
                                    HISTORY
 
     UroSurge was incorporated in Delaware in August 1993. Since its inception,
the Company has received, licensed or obtained an option or right to license 10
issued or allowed U.S. patents and five pending U.S. patent applications and has
received three FDA investigational device exemption ("IDE") approvals for U.S.
clinical trials, two FDA 510(k) clearances and CE mark certifications for two
products. The Company's achievements to date are attributable to the experience
of its management team and to the Company's relationships with opinion leaders
at major research and treatment institutions, which include Children's Hospital
and Medical Center, an affiliate of Harvard Medical School, University of Iowa,
and University of California-San Francisco ("UCSF") School of Medicine. The
Company is located at 2660 Crosspark Road, Coralville, Iowa 52241 and its
telephone number is (319) 626-8311.

                                  RISK FACTORS
 
     This Prospectus contains, in addition to historical information,
forward-looking statements that involve risks and uncertainties. The Company's
actual results may differ materially from those discussed herein. Factors that
could cause or contribute to such differences include, but are not limited to,
those discussed in the following risk factors as well as those discussed
elsewhere in this Prospectus. The following risk factors should be considered
carefully in evaluating the Company and its business before purchasing the
shares of Common Stock offered hereby.
 
     UNCERTAINTIES RELATED TO EARLY STAGE OF DEVELOPMENT. Of the Company's
products, only UroVive, percutaneous SANS, SpiraStent, FilaStent and AcuTrainer
are being marketed in Europe; only SpiraStent and AcuTrainer have been cleared
for marketing in the U.S.; and only AcuTrainer has been approved for marketing
in Japan. The products the Company is marketing in Europe may not reach the U.S.
market and future products may not reach Europe, the U.S. or any other market
for a number of reasons. Such reasons include the possibilities that the
potential products will be found ineffective or cause harmful side effects
during preclinical testing or clinical trials, fail to receive necessary
regulatory approvals or clearances, be difficult to manufacture on a large
scale, be uneconomical, fail to achieve market acceptance or be precluded from
commercialization by proprietary rights of third parties. No assurance can be
given that any of the Company's development programs will be successfully
completed, that clinical trials will generate anticipated results or will
commence or be completed as planned, that required regulatory approvals or
clearances will be obtained on a timely basis, if at all, or that any products
for which approval is obtained will contain acceptable labeling or be
commercially successful. If any of the foregoing do not occur as planned, the
Company's business, financial condition and results of operations would be
materially adversely affected.
 
     The Company's business is subject to the risks inherent in the development,
licensing and acquisition of new products using new technologies and approaches.
There can be no assurance that unforeseen problems will not develop with these
technologies or applications, that the Company will be able to successfully
address technological challenges it encounters in its research and development
programs or that commercially feasible products will ultimately be developed,
licensed or acquired by the Company. See "Business -- Research and Development."
 
     LIMITED OPERATING HISTORY; HISTORY OF LOSSES AND EXPECTATIONS OF FUTURE
LOSSES. The Company has a limited operating history upon which its prospects can
be evaluated. Such prospects must be considered in light of the substantial
risks, expenses and difficulties encountered by entrants into the medical device
industry, which is characterized by an increasing number of participants,
intense competition and a high failure rate. To date, the Company has engaged
primarily in research and development efforts, and a number of the Company's key
management and technical personnel have only recently joined the Company. To
date, the Company has only generated minimal revenues from product sales and
marketed only four of its products in Europe since March 1998. The Company has
experienced net losses since its inception and, as of December 31, 1997, the
Company had an accumulated deficit of $10.0 million. The development and
commercialization of its products will require substantial development,
regulatory, sales and marketing, manufacturing and other expenditures. The
Company expects its net losses to continue through 1999 as it continues to
expend substantial resources to build its marketing and sales organizations,
continue research and development, obtain regulatory clearances or approvals and
expand manufacturing capabilities. There can be no assurance that the Company
will ever achieve profitability or that profitability, if achieved, will be
sustained. Results of operations may fluctuate significantly from quarter to
quarter and will depend upon numerous factors, including actions relating to
regulatory and reimbursement matters, progress of clinical trials, discounts to
distributors, introduction of alternative therapies for UI and competition. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business -- Sales and Marketing," "-- Manufacturing,"
"-- Competition and Technological Change" and "-- Government Regulation."
 
     LACK OF EXTENSIVE CLINICAL DATA. UroVive and percutaneous SANS are in the
pivotal stages of clinical testing in the U.S., and clinical data obtained to
date is insufficient to demonstrate the safety and efficacy of these products
under applicable FDA regulations and regulatory guidelines. The Company
completed pilot
 
                                        7
<PAGE>   9
 
clinical trials and received FDA approval to conduct pivotal trials for UroVive
in the U.S. in December 1996. The Company obtained EC approval for UroVive in
March 1998 and anticipates submitting a PMA application to the FDA in mid-1999.
Percutaneous SANS received an Investigational Device Exemption ("IDE") approval
in the U.S. in January 1998. There can be no assurance that UroVive or
percutaneous SANS will prove to be safe and effective in clinical trials. In
addition, the clinical trials may identify significant technical or other
obstacles to be overcome prior to obtaining necessary regulatory or
reimbursement approvals. There can be no assurance that UroVive or SANS will
receive marketing approval from the FDA or that any of the Company's other
products will prove to be safe and effective or will be approved or cleared by
appropriate regulatory authorities or by health care payors. If UroVive, SANS
and the Company's other products under development do not prove to be safe and
effective in clinical trials, the Company's business, financial condition and
results of operations will be materially and adversely affected. The rate of
completion of the Company's clinical trials may be delayed by many factors,
including slower than anticipated patient enrollment or adverse events occurring
during clinical trials. Completion of preclinical and clinical activities may
take several years, and the length of time for completion of the required
studies is unpredictable. In addition, data obtained from preclinical and
clinical activities are susceptible to varying interpretations, which could
delay, limit or prevent regulatory approval. No assurance can be given that any
of the Company's clinical trials will be successfully completed on a timely
basis, or at all, that additional clinical trials will be allowed by the FDA or
other regulatory authorities or that such clinical trials will commence as
planned. See "Business -- Products and Products Under Development."
 
     DEPENDENCE ON PATENTS AND PROPRIETARY TECHNOLOGY. The Company's success
will depend on its ability to obtain patent protection for its products,
preserve its trade secrets, prevent third parties from infringing upon its
proprietary rights, and operate without infringing upon the proprietary rights
of others, both in the U.S. and internationally. There can be no assurance that
the Company's pending or future patent applications will issue, or that the
claims of the Company's issued or licensed patents, or any patents that may
issue in the future, will provide any competitive advantages for the Company's
products or that they will not be successfully challenged, narrowed, invalidated
or circumvented in the future. The Company believes that obtaining foreign
patents may be more difficult than obtaining domestic patents because of
differences in patent laws and believes the protection afforded by foreign
patents or any other foreign intellectual property protection, if obtained, may
be more limited than that provided domestically. In addition, there can be no
assurance that competitors will not seek to apply for and obtain patents that
will prevent, limit or interfere with the Company's ability to make, use, offer
for sale, sell and import its products. Because patent applications in the U.S.
are confidential until the patents issue, and publication of discoveries in the
scientific and patent literature tends to lag behind actual discoveries, the
Company cannot be certain that Company inventors or licensors were the first to
conceive of inventions covered by pending patent applications or that the
Company was the first to file patent applications for such inventions.
 
     The Company licenses certain technologies and may desire to or may be
required to obtain additional licenses to patents or proprietary rights of
others. No assurance can be given that any licenses required under any patents
or proprietary rights of third parties would remain or be made available on
terms acceptable to the Company, or at all. If the Company does not maintain or
obtain such licenses, it could encounter delays in product introductions while
it attempts to design around or otherwise avoid such patents, or it could find
that the development, manufacture or sale of products requiring such licenses is
foreclosed. In addition, the medical device industry has been characterized by
litigation regarding patents and other intellectual property rights, and many
companies in the medical device industry have employed intellectual property
litigation to gain a competitive advantage. Litigation may be necessary to
defend against or assert claims of patent infringement or invalidity, to enforce
or defend patents issued to or licensed by the Company, to protect trade secrets
or know-how owned by the Company, or to determine the scope and validity of the
proprietary rights of others. In addition, interference proceedings in the U.S.
Patent and Trademark Office, or opposition proceedings in a foreign patent
office, may be necessary to determine the priority of inventions with respect to
patent applications of the Company or its licensors. Litigation, interference or
opposition proceedings could result in substantial costs to and diversion of
effort by the Company, and adverse determinations in any such proceedings could
prevent the Company from manufacturing, marketing or selling its products and
could have a material adverse effect on the Company's business, financial
condition and results of operations.
                                        8
<PAGE>   10
 
     The Company also relies upon unpatented trade secrets and improvements,
unpatented know-how and continuing technological innovation to develop and
maintain its competitive position, which it seeks to protect, in part, by
confidentiality agreements with its employees and consultants. The Company also
has invention or patent assignment agreements with its employees and certain,
but not all, consultants. There can be no assurance that relevant inventions
will not be developed by a person not bound by an invention assignment
agreement. There can be no assurance that binding agreements will not be
breached, that the Company would have adequate remedies for any breach, or that
the Company's trade secrets will not otherwise become known or be independently
discovered by competitors. See "Business -- Patents and Proprietary Technology."
 
     LACK OF REGULATORY APPROVALS. The design, manufacturing, labeling,
distribution and marketing of the Company's products is subject to extensive and
rigorous government regulation in the U.S. and certain other countries where the
process of obtaining and maintaining required regulatory clearance or approvals
is lengthy, expensive and uncertain. In order for the Company to market its
products in the U.S., the Company must obtain clearance or approval from the
FDA. The Company is required to obtain a PMA prior to U.S. commercial sales of
its two lead products, UroVive and SANS. The PMA process can take several years
from the initial filing and requires the submission of extensive supporting data
and clinical information. The Company has received 510(k) clearance in the U.S.
for SpiraStent and AcuTrainer and marketing approval in Europe for UroVive and
AcuTrainer. The Company also has submitted applications seeking clearance to
market FilaStent and UroTherm through the 510(k) premarket notification process
and will be required to submit PMA or 510(k) applications for additional
products it is developing or may develop, license or acquire in the future.
There can be no assurance that the FDA will act favorably or quickly on such PMA
or 510(k) submissions, or that significant difficulties and costs will not be
encountered during efforts to obtain FDA clearance or approval. Specifically,
the FDA may request additional data or require additional clinical trials be
conducted to obtain clearance. In addition, there can be no assurance that the
FDA will not impose strict labeling, training or other requirements as a
condition to 510(k) clearances or PMA approvals, any of which could limit the
Company's ability to market its products. Further, if the Company wishes to
modify a product after FDA clearance of a 510(k) premarket notification or
approval of a PMA, including changes in indications or other modifications that
could affect safety and efficacy, additional clearances or approvals will be
required from the FDA. Any request by the FDA for additional data or any
requirement by the FDA that the Company conduct additional clinical trials or
submit to the more rigorous and lengthier PMA process could result in a
significant delay in bringing such products to market and substantial additional
research and other expenditures by the Company. Similarly, any labeling,
training or other conditions or restrictions imposed by the FDA on the marketing
of the Company's products could hinder the Company's ability to effectively
market its products in the U.S. Any of the foregoing actions by the FDA could
delay or prevent altogether the Company's ability to market and distribute its
products and could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     In order for the Company to market its products under development in Europe
and certain other foreign jurisdictions, the Company and its distributors and
agents must obtain required regulatory registrations or approvals and otherwise
comply with extensive regulations regarding safety, efficacy and quality in
those jurisdictions. Specifically, certain foreign regulatory bodies have
adopted various regulations governing product standards, packaging requirements,
labeling requirements, import restrictions, tariff regulations, duties and tax
requirements. These regulations vary from country to country. There can be no
assurance that the Company will be successful in maintaining ISO 9001 or CE mark
certification. Failure to maintain ISO 9001 or CE mark certification or to
obtain or maintain other foreign regulatory approvals could have a material
adverse effect on the Company's business, financial condition and results of
operations. There can be no assurance that the Company will obtain any required
regulatory registrations or approvals in such countries or that it will not be
required to incur significant costs in obtaining or maintaining such regulatory
registrations or approvals. Delays in obtaining any registrations or approvals
required to market the Company's products, failure to receive these
registrations or approvals, or future loss of previously obtained registrations
or approvals could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
                                        9
<PAGE>   11
 
     The Company will be required to adhere to applicable FDA Quality System
Regulations ("QSR"), which incorporate the FDA's former Good Manufacturing
Practice ("GMP") regulations, and similar regulations in other countries that
impose testing, control and documentation requirements. Ongoing compliance with
applicable QSRs and other applicable regulatory requirements will be strictly
enforced in the U.S. through periodic inspections by state and federal agencies,
including the FDA, and in foreign jurisdictions by comparable agencies. Failure
to comply with applicable regulatory requirements could result in, among other
things, warning letters, fines, injunctions, civil penalties, recall or seizure
of products, total or partial suspension of production, refusal of the
government to grant premarket clearance or premarket approval for devices,
withdrawal of approvals previously obtained and criminal prosecution. The
restriction, suspension or revocation of regulatory approvals or any other
failure to comply with regulatory requirements would have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business -- Government Regulation."
 
     UNCERTAINTY OF MARKET ACCEPTANCE. The Company's products are based upon new
methods of treating UI and there can be no assurance that these products will
gain commercial acceptance among physicians, patients and health care payors,
even if necessary international and U.S. marketing approval is obtained. The
Company believes that recommendations and endorsements by physicians will be
essential for market acceptance of its products and there can be no assurance
that any such recommendations or endorsements will be obtained. Market
acceptance of the Company's products will also be dependent upon the Company's
ability to convince health care payors and providers that such products
represent cost-effective alternatives to existing therapies. Such assessments of
cost-effectiveness will depend in large part upon the duration of relief from UI
provided by the Company's products, and a thorough analysis of long-term patient
follow-up data may be necessary to assess such durability. Failure of the
Company's products to achieve significant market acceptance would have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Products and Products Under
Development."
 
     COMPETITION. The medical device industry in general and the market for
products and treatments in the area of UI in particular are highly competitive.
In Europe, the Company competes and, in the U.S., the Company will compete with
other providers of products and treatments for UI. There is currently one
urethral bulking agent for stress UI and one implantable nerve stimulation
device for urge UI approved for commercial sale in the U.S. and other such
products are in development. In addition, a number of competitors are currently
marketing products, such as absorbents and pharmaceuticals, to treat UI. Some of
these products are widely accepted in the health care industry and have a long
history of use.
 
     Many of the Company's current and potential competitors have substantially
greater financial, research, technical, manufacturing, marketing and
distribution resources than the Company and have greater name recognition and
lengthier operating histories in the health care industry. There can be no
assurance that the Company will be able to compete effectively against these and
other competitors or that the Company's products will replace any currently used
devices or systems. Furthermore, there can be no assurance that the Company's
competitors will not succeed in developing, either before or after the
development and commercialization of the Company's products, devices and
technologies that permit more efficient, less expensive and less invasive
treatment of UI. It is also possible that one or more pharmaceutical or other
health care companies will develop therapeutic drugs, treatments or other
products that will substantially reduce the prevalence of UI or otherwise render
the Company's products obsolete or irrelevant. Such competition could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Competition and Technological Change."
 
     LIMITED MANUFACTURING EXPERIENCE. The Company is currently scaling up its
manufacturing facilities for clinical and early commercial production of its
products. The Company does not have experience in manufacturing its products in
commercial quantities. There can be no assurance that the Company will be able
to attract, train and retain the required personnel or will be able to
manufacture commercial quantities of its products in a timely manner, or at all.
Manufacturers often encounter difficulties in scaling up production of their
products, including problems involving production yields, quality control and
assurance, component supply and shortages of qualified personnel. There can be
no assurance that the Company's manufacturing scale-up efforts will be
successful or that reliable, high-volume manufacturing can be established or
                                       10
<PAGE>   12
 
maintained at commercially reasonable costs on a timely basis, or at all. In
addition, there can be no assurance that the Company will not encounter
unanticipated problems and delays in connection with its contract manufacturers
and suppliers. Delays associated with or difficulties encountered in
establishing high-volume manufacturing, or problems encountered with contract
manufacturers and suppliers, would result in disruptions of product supply. Any
of the foregoing would have a material adverse affect on the Company's business,
financial condition and results of operations.
 
     Medical devices, such as the Company's products, can experience performance
problems in the field that require review and possible corrective action by the
manufacturer. There can be no assurance that component failures, manufacturing
errors or design defects that could result in an unsafe condition or injury to
the patient will not occur. If any such failures or defects were deemed serious,
the Company could be required to withdraw or recall products, which could result
in significant costs to the Company. Any future product problems could result in
market withdrawals or recalls of products, which could have a material adverse
affect on the Company's business, financial condition and results of operations.
Furthermore, prior to approval of a PMA application, the Company's facilities,
procedures and practices, and the facilities, procedures and practices of its
third-party manufacturers, will be subject to a preapproval inspection by the
FDA. In addition, if the Company wishes to significantly modify its
manufacturing processes or change the supplier of a critical component,
additional approvals will be required from the FDA before the change can be
implemented. Failure to maintain compliance with the applicable regulatory
requirements of various regulatory agencies would have a material adverse effect
on the Company's business, financial condition and results of operations. See
"Business -- Manufacturing."
 
     DEPENDENCE UPON KEY SUPPLIERS. One of the primary components for the
manufacture of UroVive, the microballoon, is purchased by the Company from a
single source under a mutually exclusive supply agreement that expires in April
2000, subject to an automatic two-year extension. Other raw materials and
components used in the Company's products are purchased from various suppliers.
These materials have generally been readily available in the marketplace and
have not been the subject of shortages. There can, however, be no assurance that
the Company or its suppliers or contract manufacturers will not experience
shortages of materials in the future. Delays associated with any such future
shortages of materials or components, particularly as the Company scales up its
manufacturing activities in support of commercial sales, could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business -- Manufacturing."
 
     LIMITED MARKETING AND SALES CAPABILITIES. The Company currently has limited
experience in marketing and selling its products. In order to achieve commercial
success for any product, UroSurge must increase its marketing and sales
capabilities or enter into arrangements with third parties to market and sell
its products. There can be no assurance that UroSurge will successfully develop
such marketing and sales capabilities or experience. As the Company develops its
own marketing and sales capabilities, it will compete with other companies that
currently have experienced and well-funded marketing and sales operations.
 
     The Company markets and sells its products outside the U.S. primarily
through a network of international distributors, and the Company's international
sales are largely dependent on the marketing efforts of, and sales by, these
distributors. Sales through distributors are subject to several risks, including
the risk of financial instability of the distributors and the risk that
distributors will not effectively promote the Company's products. There can be
no assurance that the efforts of these third parties for the marketing and sale
of the Company's products will be successful. See "Business -- Sales and
Marketing."
 
     INTERNATIONAL SALES AND OPERATING RISKS. The Company's limited sales of
UroVive, percutaneous SANS, SpiraStent and FilaStent have been outside the U.S.,
and the Company anticipates that a significant portion of its revenues for the
next several years will also be derived from international sales of its
products. A number of risks are inherent in international operations and
transactions. International sales and operations may be limited or disrupted by
the imposition of government controls, export license requirements, political
instability, trade restrictions, changes in tariffs or difficulties in staffing
and managing international operations. Foreign regulatory agencies often
establish product standards different from those in the U.S. and any inability
 
                                       11
<PAGE>   13
 
to obtain foreign regulatory approvals on a timely basis could have an adverse
effect on the Company's international business and its financial condition and
results of operations. Additionally, the Company's business, financial condition
and results of operations may be adversely affected by fluctuations in currency
exchange rates as well as increases in duty rates. There can be no assurance
that the Company will be able to successfully commercialize its existing or
future products in any foreign market. See "Business -- Sales and Marketing."
 
     NO ASSURANCE OF ABILITY TO MANAGE GROWTH. If demand for the Company's
products develops and grows, there can be no assurance that the Company will be
able to develop the necessary manufacturing capability for its products; build
the international sales and marketing capability for products; attract, retain
and integrate the required personnel; or implement the financial and management
systems necessary to meet the growing demand for its products. Failure of the
Company to successfully manage its growth could have a material adverse effect
on the Company's business, financial condition and results of operations. See
"Business -- Sales and Marketing," "-- Manufacturing," "-- Employees,"
"-- Facilities" and "Management."
 
     PRODUCT LIABILITY RISK; LIMITED INSURANCE COVERAGE. The development,
manufacture and sale of medical products entail significant risks of product
liability claims. The Company has product liability insurance subject to
specified coverage limits. There can no assurance that such insurance coverage
will be adequate to protect the Company from any liabilities, including any
adverse judgments or settlements, it might incur in connection with the
development, clinical testing, manufacture and sale of its products. In
addition, product liability insurance is expensive and may in the future not be
available to the Company on acceptable terms, if at all. A successful product
liability claim or series of claims brought against the Company that results in
an adverse judgment against or settlement by the Company in excess of any
insurance coverage could have a material adverse effect on the Company's
business, financial condition and results of operations. See
"Business -- Product Liability."
 
     POSSIBLE FUTURE CAPITAL REQUIREMENTS. To the extent that the Company is
unable to successfully commercialize its products or experiences delays in
completing product testing and clinical trials or obtaining regulatory approvals
and clearances, it may be required to raise additional funds through public or
private financing or other arrangements. The Company believes that its existing
capital resources and the net proceeds of this offering will be sufficient to
satisfy its funding requirements through 1999. There can be no assurance that
any required additional funding, if needed, will be available on terms
attractive to the Company, or at all, which could have a material adverse effect
on the Company's business, financial condition and results of operations. Any
additional equity financing may be dilutive to stockholders, and debt financing,
if available, may involve restrictive covenants. See "Use of Proceeds" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
     UNCERTAINTY RELATING TO THIRD-PARTY REIMBURSEMENT. The Company's success
will be dependent upon, among other things, the ability of users of its products
to obtain satisfactory reimbursement from health care payors for the Company's
products and procedures employing such products. In the U.S. and international
markets, sales of medical products are dependent, in part, on the ability of
consumers of these products to obtain reimbursement for all or a portion of
their cost from third-party payors, such as government and private insurance
plans. Currently, third-party reimbursement is available for some existing
therapies used in the treatment of UI (other than for diapers and absorbents).
After such time, if ever, as FDA approval or clearance is received, third-party
reimbursement for UroVive and SANS will be dependent upon decisions by the
Health Care Financing Administration ("HCFA") for Medicare and Medicaid, as well
as by individual health maintenance organizations, private insurers and other
payors. Such reimbursement approvals will depend in part on the Company's
ability to convince payors that such products represent cost-effective
alternatives to existing therapies. Such assessments of cost-effectiveness will
depend in large part upon the duration of the relief from UI provided by the
Company's products, and a thorough analysis of long-term patient follow-up data
may be necessary to assess such durability. In addition, the Company has not
applied for or received either Medicare or private payor reimbursement approvals
for SpiraStent or AcuTrainer, and growth in SpiraStent or AcuTrainer sales in
the U.S. will be dependent upon the Company's ability to obtain such
reimbursement approvals.
                                       12
<PAGE>   14
 
     Reimbursement systems in international markets vary significantly by
country. Many international markets have governmentally managed health care
systems that govern reimbursement for new devices and procedures. In most
markets, there are private insurance systems as well as governmentally managed
systems. Market acceptance of the Company's products will depend on the
availability of reimbursement in international markets targeted by the Company
and will require reimbursement approvals in addition to those already obtained.
 
     Regardless of the type of reimbursement system, the Company believes that
physician advocacy of the Company's products will be required to obtain
reimbursement. There can be no assurance that reimbursement will be available or
sufficient to allow the Company to sell its products on a competitive basis, or
that physicians will support reimbursement for the Company's procedures.
Furthermore, the Company could be adversely affected by changes in reimbursement
policies of governmental or private health care payors. Failure by physicians,
hospitals and other users of the Company's products to obtain sufficient
reimbursement from health care payors or adverse changes in governmental and
private third party payor's policies toward reimbursement for procedures
employing the Company's products would have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business -- Third-Party Reimbursement."
 
     DEPENDENCE UPON KEY PERSONNEL. The Company's ability to operate
successfully and manage its potential future growth depends in significant part
upon the continued service of certain key scientific, technical, managerial and
finance personnel and its ability to attract and retain additional highly
qualified scientific, technical, managerial and finance personnel. None of these
key employees has an employment contract with the Company nor are any of these
employees covered by key person or similar insurance. The Company faces intense
competition for qualified personnel, many of whom are often subject to competing
employment offers, and there can be no assurance that the Company will be able
to attract and retain such personnel. The loss of key personnel or inability to
hire and retain additional qualified personnel in the future could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Employees."
 
     NO PRIOR PUBLIC MARKET FOR COMMON STOCK. Prior to this offering, there has
been no public market for the Company's Common Stock, and there can be no
assurance that a regular trading market will develop and continue after this
offering or that the market price of the Common Stock will not decline below the
initial public offering price. The initial public offering price will be
determined through negotiations between the Company and the Underwriters and may
bear no relationship to the price at which the Common Stock will trade after
completion of this offering. The factors to be considered in determining the
initial public offering include the history of and the prospects for the
industry in which the Company competes, the past and present operations of the
Company, the historical results of operation of the Company, the prospects for
future earnings of the Company, the recent market prices of securities of
generally comparable companies and the general condition of the securities
markets at the time of the offering. See "Underwriting."
 
     VOLATILITY OF COMMON STOCK PRICE. The market prices for securities of
medical device companies have historically been highly volatile, and the market
has from time to time experienced significant price and volume fluctuations that
are unrelated to the operating performance of particular companies. Factors such
as fluctuations in the Company's operating results, announcements of
technological innovations or new therapeutic products by the Company or others,
clinical trial results, government regulation, developments in patent or other
proprietary rights, public concern as to the safety of products developed by the
Company or others, future sales of substantial amounts of Common Stock by
existing stockholders, comments by securities analysts and general market
conditions can have an adverse effect on the market price of the Common Stock.
In addition, the realization of any of the risks described in these "Risk
Factors" could have a dramatic and material adverse impact on the market price
of the Company's Common Stock.
 
     CONTROL BY EXISTING STOCKHOLDERS. After the completion of this offering,
current stockholders, including certain executive officers and directors of the
Company and their affiliates, will own approximately      % of the outstanding
Common Stock. As a result, these stockholders will, to the extent they act
together, continue to have the ability to exert significant influence and
control over matters requiring the approval of the
 
                                       13
<PAGE>   15
 
Company's stockholders, including the election of a majority of the Company's
Board of Directors. See "Principal Stockholders."
 
     SHARES ELIGIBLE FOR FUTURE SALE. Sales of Common Stock (including shares
issued upon the exercise of outstanding options) in the public market after this
offering could materially adversely affect the market price of the Common Stock.
Such sales also might make it more difficult for the Company to sell equity
securities or equity-related securities in the future. Upon completion of this
offering, the Company will have                shares of Common Stock
outstanding, of which the                shares offered hereby will be freely
tradable (unless held by affiliates of the Company). As a result of lock-up
agreements between certain stockholders and Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ"), the remaining 6,956,037 shares will not become
available for sale in the public market until 180 days after the date of this
Prospectus, subject in some cases to the volume and other restrictions of Rule
144 and Rule 701 under the Securities Act of 1933, as amended (the "Securities
Act"). However, DLJ may, in its sole discretion and at any time without notice,
release all or any portion of the securities subject to the lock-up agreements.
See "Shares Eligible for Future Sale" and "Underwriting."
 
     ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER AND BYLAW PROVISIONS ON PRICE OF
COMMON STOCK. Certain provisions of the Company's Certificate of Incorporation
and Bylaws may have the effect of making it more difficult for a third party to
acquire, or of discouraging a third party from attempting to acquire, control of
the Company. Such provisions could limit the price that certain investors might
be willing to pay in the future for shares of the Company's Common Stock.
Certain of these provisions allow the Company to issue Preferred Stock without
any vote or further action by the stockholders, eliminate the right of
stockholders to act by written consent without a meeting and specify procedures
for director nominations by stockholders and submission of other proposals for
consideration at stockholder meetings. Certain provisions of Delaware law
applicable to the Company, including Section 203 of the Delaware General
Corporation Law, which prohibits a Delaware corporation from engaging in any
business combination with any interested stockholders for a period of three
years unless certain conditions are met, could also delay or make more difficult
a merger, tender offer or proxy contest involving the Company. The possible
issuance of Preferred Stock, the procedures required for director nominations
and stockholder proposals and Delaware law could have the effect of delaying,
deferring or preventing a change in control of the Company. See "Description of
Capital Stock -- Preferred Stock" and "-- Certain Charter and Bylaws Provisions
and Delaware Anti-Takeover Statute."
 
     DILUTION. Purchasers of Common Stock in this offering will experience
immediate and substantial dilution of $     per share in the net tangible book
value of the Common Stock from the initial public offering price. Additional
dilution is likely to occur upon the exercise of options, warrants and
conversion rights granted by the Company. See "Dilution."

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the           shares of
Common Stock offered hereby at an assumed initial public offering price of
       per share are estimated to be        million (       million if the
Underwriters' over-allotment option is exercised in full) after deducting the
underwriting discounts and commissions and the estimated expenses of this
offering.
 
     The Company expects to use a majority of the net proceeds to fund increased
research and development activities, including clinical trials, expansion of
marketing and sales activities, expansion of manufacturing capabilities and
capital expenditures. The Company intends to use the remaining net proceeds for
working capital, general and administrative expenses and general corporate
purposes. The amounts actually expended for each purpose and the timing of such
expenditures may vary significantly depending upon numerous factors, including
the timing of regulatory actions regarding the Company's products, the cost and
timing of expansion of marketing, sales and manufacturing activities, results of
clinical trials and competition. The Company may also use a portion of the net
proceeds for the licensing or acquisition of technologies, businesses or
products that are complementary to those of the Company. No such acquisitions
are currently planned or are being negotiated, and no portion of the net
proceeds has been allocated for any specific licensing or acquisition. Pending
such uses, the Company intends to invest the net proceeds of this offering in
short-term, interest-bearing, investment grade securities.
 
     In addition, a portion of the net proceeds may be used to repay certain
amounts the Company may borrow from stockholders under a financing arrangement.
Under this arrangement, which is expected to be entered into in April 1998,
certain principal stockholders would provide the Company with a line of credit
of up to $5.0 million in the event that the Company requires any additional
funding prior to receiving the net proceeds from this offering. In exchange for
this line, the Company has agreed to issue warrants to the stockholders to
purchase an aggregate of 50,000 shares of Common Stock at the initial public
offering price per share. The remaining terms of this credit facility are
currently being negotiated by the Company and such stockholders. To date, the
Company has not borrowed any amounts under this arrangement.
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid any dividends on its capital stock.
The Company does not anticipate declaring or paying any cash dividends in the
foreseeable future.

     The following table sets forth, as of December 31, 1997, (i) the actual
capitalization of the Company and (ii) the as adjusted capitalization of the
Company reflecting the conversion of all outstanding shares of Preferred Stock

receipt of the proceeds therefrom, after deducting underwriting discounts and
commissions and estimated offering expenses payable by the Company; and the
restatement of the Company's Certificate of Incorporation to increase the
authorized number of shares of Common Stock to 50,000,000 shares and create a

                                    DILUTION
 
     The pro forma net tangible book value of the Company's Common Stock as of
December 31, 1997, was $4,240,638 or $0.61 per share. Pro forma net tangible
book value per share represents the amount of the Company's total tangible
assets less total liabilities, divided by the number of shares of Common Stock
outstanding after giving effect to the conversion of outstanding shares of
Preferred Stock into Common Stock upon the completion of this offering. After
giving effect to the sale of the shares of Common Stock offered hereby (at an
assumed initial public offering price of $     per share) and after deducting
underwriting discounts and commissions and estimated offering expenses, the
Company's pro forma net tangible book value as of December 31, 1997 would have
been approximately $          or $     per share. This represents an immediate
increase in pro forma net tangible book value of $     per share to existing
stockholders and an immediate dilution in net tangible book value of $     per
share to new investors purchasing shares of Common Stock in this offering. The
following table illustrates this per share dilution:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     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 materially from those discussed herein. Factors that could cause or
contribute to such differences include, but are not limited to, those discussed
in "Risk Factors" as well as those discussed elsewhere in this Prospectus. The
following discussion should be read in conjunction with the Company's financial
statements and notes thereto included elsewhere in this Prospectus.
 
OVERVIEW
 
     UroSurge develops, manufactures and markets medical devices for the
treatment and management of genito-urinary disorders. The Company believes that
its lead products, UroVive and SANS, represent a significant revenue opportunity
in Europe and the U.S. Additionally, the Company has a number of other products
approved or in development to treat a variety of urological conditions. The
Company commenced marketing UroVive, percutaneous SANS, SpiraStent, FilaStent
and AcuTrainer in Europe and other international markets in March 1998 and is
recognizing revenues from these efforts in the second quarter of 1998. The
Company is marketing SpiraStent and AcuTrainer in the U.S. and intends to
commence marketing UroVive and percutaneous SANS in the U.S. upon receipt of PMA
approval. In addition, the Company has submitted 510(k) clearance applications
for FilaStent and UroTherm.
 
     Since its inception, the Company has financed operations primarily through
the private placement of equity securities totaling $14.4 million. The Company
has incurred net losses in each year since its inception, including net losses
of $5.3 million in 1997, $2.8 million in 1996 and $1.2 million in 1995. The
Company's net losses have resulted primarily from expenses incurred in
connection with the Company's research and development activities, including
clinical and preclinical trials, development of manufacturing processes, general
and administrative expenses and sales and marketing expenses. The Company
expects to incur net losses through at least 1999 and may incur net losses in
subsequent periods although the amount of future net losses and time required by
the Company to reach profitability are highly uncertain. Although the Company
only sold limited numbers of AcuTrainers in 1996 and 1997, it is recognizing
revenues from the sale of UroVive, percutaneous SANS, SpiraStent, FilaStent and
AcuTrainer in Europe in the second quarter of 1998. The Company will not
generate revenues from commercial sales of UroVive, percutaneous SANS and
FilaStent in the U.S. unless FDA approvals are received.
 
     The Company has entered into license agreements with various parties under
which the Company obtained certain intellectual property rights relating to its
products. See "Business -- Patents and Proprietary Rights." The Company is
obligated to pay royalties of up to 6% on sales of all of its products, except
for FilaStent and UroTherm, under such license agreements. The Company currently
accounts for such royalties as operating expenses. The Company is also obligated
to make certain milestone payments under these license agreements, which could
aggregate approximately $1.0 million.
 
     The Company intends to sell its products through a direct sales force in
the U.S. and through local distributors in foreign markets with non-exclusive
rights in their respective designated territories. The Company expects gross
margins on U.S. sales to be higher than gross margins on international sales due
to distributor discounts. The Company believes its gross margins will be
primarily affected by product mix, manufacturing costs, sales channels and
product pricing.
 
RESULTS OF OPERATIONS
 
  FISCAL YEAR ENDED DECEMBER 31, 1997 COMPARED TO FISCAL YEAR ENDED DECEMBER 31,
1996
 
     Net revenues decreased to $12,000 in 1997 from $20,000 in 1996. AcuTrainer
was the only product sold commercially by the Company during these periods and
is expected to comprise only a small portion of the Company's future revenues.
The Company's primary focus has been on the development of UroVive and SANS and,
as a result, the Company did not devote significant sales efforts to AcuTrainer
sales. The
 
                                       19
<PAGE>   21
 
Company is recognizing revenues from sales of UroVive and percutaneous SANS in
Europe in the second quarter of 1998.
 
     Research and development expenses increased to $3.6 million in 1997 from
$1.9 million in 1996. This increase was due primarily to increased costs of
development, including materials for UroVive and SANS pivotal clinical trials
and preclinical animal testing for the Company's other products. In addition,
the increase in expense is associated with the Company's build-up of its
research and development personnel as well as payments to consultants. The
Company currently employs 17 individuals in research and development and
manufacturing on a full-time basis and five individuals on a part-time basis.
Research and development expenses are expected to increase as the Company
continues to develop its products.
 
     Marketing and sales expenses increased to $392,000 in 1997 from $271,000 in
1996. This increase was due to the Company's build-up of its sales and marketing
personnel, which currently includes six executives and two telemarketers. In
addition, the Company is continuing to develop promotional materials, train
physicians and attend trade shows, which also contributes to the increase in
such expenses. Marketing and sales expenses are expected to increase as the
Company commercializes its products and completes the hiring of a direct sales
force in the U.S.
 
     General and administrative expenses increased to $1.5 million in 1997 from
$771,000 in 1996. This increase was due primarily to increased personnel costs
and associated costs related to obtaining product clearances and establishing
administrative functions to support the Company's operations. General and
administrative expenses are expected to increase as additional personnel are
hired to support the Company's operations and needs as a public company, but at
a lower rate than research and development and marketing and sales expenses.
 
     Interest income increased to $187,000 in 1997 from $184,000 in 1996.
Interest expense increased to $9,000 in 1997 from $6,000 in 1996.
 
     With respect to certain stock options made during 1997, the Company is
recognizing compensation charges of $860,000. The Company recognized $122,000 of
the compensation charges in 1997, and will recognize the remainder over the
related vesting period. The future compensation charges are subject to reduction
for any employee who terminates employment prior to the expiration of such
employee's vesting period. See Note 5 of notes to the Company's financial
statements.
 
  FISCAL YEAR ENDED DECEMBER 31, 1996 COMPARED TO FISCAL YEAR ENDED DECEMBER 31,
1995
 
     Net revenues were $20,000 in 1996 as a result of sales of AcuTrainers. No
revenues were recorded in 1995.
 
     Research and development expenses increased to $1.9 million in 1996 from
$848,000 in 1995. This increase was due to increased costs for the development
of UroVive and SANS, including pilot clinical studies and preclinical animal
testing, the associated costs for the hiring of research and development
personnel and consultants and increased material and prototype expenses.
 
     Marketing and sales expenses increased to $271,000 in 1996 from $2,000 in
1995. This increase was due primarily to advertising costs for AcuTrainer and
image brochures regarding the Company.
 
     General and administrative expenses increased to $771,000 in 1996 from
$466,000 in 1995. This increase was due primarily to increased personnel and
associated costs related to obtaining an IDE for UroVive and a 510(k) clearance
for AcuTrainer and establishing administrative functions to support the
Company's operations.
 
     Interest income increased to $184,000 in 1996 from $85,000 in 1995. This
increase is due primarily to higher cash balances as a result of a $5.3 million
private placement of equity securities completed in September and October 1995.

LIQUIDITY AND CAPITAL RESOURCES
 
     From inception through December 31, 1997, the Company has financed
operations primarily through the private placement of equity securities totaling
$14.4 million. The Company's principal source of liquidity as of December 31,
1997 consisted of cash, cash equivalents and short-term investments of $3.3
million. The Company's cash used in operating activities increased to $5.7
million in 1997 from $2.5 million in 1996, primarily resulting from an increase
in the Company's net loss due to increased research and development, sales and
marketing, and general and administrative expenses for preparation and support
of clinical trials for UroVive and percutaneous SANS.
 
     As of December 31, 1997, the Company had approximately $110,000 in
long-term debt. The Company expects to enter into a financing arrangement with
certain of its principal stockholders during April 1998. Under this arrangement,
such stockholders would provide the Company with a line of credit of up to $5.0
million in the event that the Company requires any additional funding prior to
receiving the net proceeds of this offering. In exchange for this line, the
Company has agreed to issue warrants to purchase an aggregate of 50,000 shares
of Common Stock at the initial public offering price per share. The remaining
terms of this credit facility are currently being negotiated by the Company and
such stockholders. To date, the Company has not borrowed any amounts under this
arrangement.
 
     The Company is completing improvements to a leased building to be used as a
manufacturing facility. Leasehold improvements and other capital equipment
purchases with an estimated cost of $500,000 are anticipated through the second
quarter of 1998. The Company does not anticipate that material capital or other
expenditures will be necessary in connection with computer problems associated
with year 2000 concerns.
 
     The Company believes that the proceeds from this offering together with
current cash balances will be sufficient to meet the Company's operating and
capital requirements through 1999. The Company's liquidity and capital
requirements will depend on numerous factors, including the extent to which the
Company's products gain market acceptance, the timing of regulatory actions
regarding the Company's products, the costs and timing of expansion of sales,
marketing and manufacturing activities, obtaining and enforcing patents
important to the Company's business, results of clinical trials and competition.
There can be no assurance that the Company will not be required to raise
additional capital, or that such capital will be available on acceptable terms,
or at all.

                                    BUSINESS
OVERVIEW
 
     UroSurge develops, manufactures and markets medical devices for the
treatment and management of genito-urinary disorders. The Company is developing
a broad range of proprietary products to address segments of the urology market
that are currently underserved as a result of ineffective or costly therapies.
The Company is initially focusing much of its efforts on addressing UI, which
afflicts approximately 13 million people in the U.S. and accounts for
approximately $15 billion in annual treatment costs. The UI market presents a
significant opportunity because approximately two-thirds of UI sufferers are
dissatisfied with current treatment alternatives according to a recent U.S.
study by the National Association for Continence. The Company believes that its
lead products, UroVive for stress UI and SANS devices for urge UI, represent
superior alternatives to existing therapies by offering minimally invasive,
cost-effective, long-term solutions for patients suffering from these
conditions. The Company launched these products in Europe in March 1998 and is
currently conducting pivotal clinical trials in the U.S. Additionally, the
Company is developing and marketing a number of other products to treat a
variety of urological conditions.
 
     UroVive is a minimally invasive urethral bulking system for the treatment
of certain types of stress UI. The UroVive procedure involves the permanent
implantation of one or more hydrogel-filled microballoons around the urethra and
is designed to close the bladder neck and immediately restore urinary
continence. The procedure can be performed in about 20 minutes in an outpatient
setting under local anesthesia. The Company believes that UroVive is a
practical, safe, long-term solution and is more convenient and cost-effective
than palliative approaches such as diapers and urethral plugs that do not cure
the problem. The Company also believes that UroVive offers significant
advantages over competing injectable urethral bulking agents that suffer from
problems of absorption and migration (which can lead to the need for repeat
procedures or raise safety concerns) and are not easily retrievable should
urinary retention occur. UroVive also provides an advantage over invasive
surgical procedures, which are costly and can result in post-surgical
complications. The Company is marketing UroVive in Europe under CE mark
certification, and is currently conducting pivotal clinical trials of UroVive in
the U.S. Results of pilot clinical trials indicate a 90% efficacy rate for
patients with the target indication for which the Company has 18-month follow-up
data. By comparison, clinical results of the only urethral bulking agent sold
commercially in the U.S. indicate only a 52% probability that such patients will
maintain their initial continence for one year. The Company expects to submit a
PMA application to the FDA for UroVive in mid-1999.
 
     The Company has two SANS devices, percutaneous (through the skin) and
subcutaneous (below the skin), for the treatment of urge UI. Both are minimally
invasive systems that modulate bladder action through stimulation of the
afferent nerve fibers in the ankle area that lead to nerves located in the
spinal region that control bladder function. Such stimulation has been shown to
greatly reduce the likelihood that the patient will have an uncontrollable spasm
of the bladder wall muscle that can cause the bladder to empty. The percutaneous
SANS procedure entails approximately 30 minutes of electrical stimulation and is
repeated weekly in a physician's office. Percutaneous SANS consists of a
generator that delivers electrical impulses through a small disposable needle,
temporarily inserted near the ankle, and lead wire assembly. To facilitate
in-home use and enhance patient convenience, the Company is developing a second
generation, subcutaneous SANS device that involves the permanent implant of a
small, thumbtack-shaped electronic receiver near the patient's ankle,
eliminating the need for the use of a needle with each treatment. Few products
exist for effectively treating urge UI and the Company believes that SANS is
superior to other commercially available products due primarily to its minimally
invasive nature and cost-effectiveness. Clinical studies to date on percutaneous
SANS, encompassing over 1,000 treatment procedures in 90 patients with average
follow-up in excess of two years, indicate an 80% efficacy rate and no
complications. By comparison, clinical results of the only commercially
available implantable electronic nerve stimulation device also indicate a
comparable efficacy rate, but a high rate of post-treatment complications that
required reoperation in approximately one-third of all cases. This competing
product involves an invasive surgical implant procedure in the spinal area and
requires extensive physician training. The Company is marketing percutaneous
SANS in Europe and is currently conducting a pivotal clinical trial in the U.S.
The Company expects to submit a PMA application for acute use of percutaneous
SANS by early 1999.
 
                                       22
<PAGE>   24
 
     As part of its strategy of offering a broad range of products to physicians
treating genito-urinary disorders, the Company has also developed or licensed
SpiraStent, FilaStent and a kidney stone grasper for use in removing kidney
stones; AcuTrainer for diagnosing and managing urge UI; UroTherm for warming
irrigation fluids used in various gynecological and urological procedures;
demineralized bone paste for use in treating VUR in infants and children; and a
urethral pressure catheter for the diagnosis of stress UI. The Company has
received FDA 510(k) clearance for U.S. marketing of SpiraStent and AcuTrainer,
and has submitted 510(k) clearance applications for FilaStent and UroTherm. The
Company is marketing SpiraStent, FilaStent and AcuTrainer in Europe and
SpiraStent and AcuTrainer in the U.S.
 
STRATEGY
 
     The Company's objective is to establish itself as the leader in the
development and commercialization of clinically effective solutions for UI and
other genito-urinary disorders treated by urologists, urogynecologists and
gynecologists. The following are the key elements of the Company's strategy.
 
     Accelerate Commercialization of Existing Products. The Company has
substantially developed the infrastructure, including international
distributors, manufacturing capabilities and sales and marketing management,
that will help accelerate the commercialization of its products. The Company is
marketing UroVive, percutaneous SANS, SpiraStent, FilaStent and AcuTrainer in
Europe and other international markets and is recognizing revenues from these
efforts in the second quarter of 1998. The Company is also marketing SpiraStent
and AcuTrainer in the U.S. and intends to commence marketing of UroVive and SANS
in the U.S. upon receipt of PMA approval.
 
     Become the Leader in the Treatment of UI. UI is a significant problem for a
large number of adults, particularly women and the elderly, and is one of the
most intractable and debilitating conditions treated by urologists and
urogynecologists. The UI market offers significant potential due primarily to
the inadequacy of existing treatments. The Company intends to offer improved
approaches for all levels of care, ranging from diagnosis to surgery, and for
all types of UI. The Company is focusing on the development of products that are
highly effective and minimally invasive, as compared to many current approaches
for managing UI, which are either palliative, such as diapers, or involve
invasive open surgical procedures.
 
     Offer a Comprehensive Product Line. Urologists, urogynecologists and
gynecologists are responsible for treating most genito-urinary disorders and use
a wide range of products. The Company is developing a broad line of products to
address the needs of these physicians while focusing on product opportunities
that represent significant improvements over currently available therapies. As
part of these efforts, the Company intends to explore the applicability of its
current products and technologies to additional clinical indications. The
Company also continually evaluates product concepts and technologies that may
present potential solutions for unmet needs in its targeted markets and, in
addition to internal development efforts, actively seeks to license or acquire
rights to such products and technologies.
 
     Penetrate International Markets. The Company believes that there is a
significant international market for its products. The Company distributes
products internationally through local distributors on a country-by-country
basis to access such distributors' established networks and specialized
expertise regarding the health care system, including reimbursement practices,
in their respective markets. The Company's current distributors cover 14
European countries, South Korea, Australia and Japan. In addition, as part of
its international marketing efforts, the Company has established clinical
research relationships with leading international urologists. The Company
believes that its country-specific approach will accelerate sales growth,
provide comprehensive geographic market coverage and enable the Company to
access particular markets and customers.
 
     Build Specialized, Direct Sales Force in the U.S. According to industry
sources, there are approximately 8,000 urologists and 800 urogynecologists in
the U.S. The Company believes that this relatively small number of physicians to
which it will market its products affords a unique opportunity to develop a
cost-effective, direct sales effort. Accordingly, the Company has retained all
U.S. sales and marketing rights to its products and has commenced building a
sales and marketing sales force in the U.S. To gain acceptance of its products,
the Company conducts physician training and disseminates clinical and patient
outcome data. In addition, the
                                       23
<PAGE>   25
 
Company markets its products by raising patient awareness of its available
treatments through advertising, magazine articles and other media.
 
URINARY INCONTINENCE
 
     In the normal urinary tract, continence, or the appropriate storage of
urine, is maintained by a complex interplay of anatomic structures. The primary
structures responsible for controlling continence are the bladder neck and the
urinary sphincter. The urinary sphincter is a muscle at the base of the bladder
that surrounds the bladder neck and urethra and aids the bladder in maintaining
continence. In a normal system, the bladder neck and the urinary sphincter work
in a coordinated fashion to act as a valve. As the bladder fills and relaxes,
the urinary sphincter contracts to prevent urination. During urination, the
urethra and urinary sphincter muscle relax and open, the bladder contracts and
the bladder neck opens, all in a coordinated fashion, causing the passage of
urine. In normal continence, when the bladder neck opens involuntarily in
response to intra-abdominal pressure, the lower portion of the urinary sphincter
tightens in turn so as to maintain continence. Similarly, the urethra is also
under muscular control so as to keep this tube closed during the urine storage
phase. The following diagram depicts the anatomy of the urinary tract.
 
[DIAGRAM OF URINARY TRACT]
 
     A malfunction in any part of this system can cause UI. The most common
anatomic incontinence pathology is bladder neck or urethral hypermobility, which
results from a lack of bladder neck support caused primarily by weak surrounding
tissue. The weakening of tissue surrounding the bladder, urethra and bladder
neck arises most commonly in women as a consequence of pelvic trauma cause by
pregnancy and childbirth. Other causes of UI include birth defects, injuries to
the pelvic region or to the spinal cord, neurological diseases and degenerative
changes associated with aging.
 
     UI may cause depression, discomfort and embarrassment about appearance and
odor. Patients suffering from UI may withdraw from social interaction with
others, including friends and family, and sexual activity may be restricted or
avoided entirely. Spouses and other intimates also may share the burden of the
condition. There are three main categories of UI.
 
     Stress urinary incontinence. Stress UI refers to the involuntary loss of
urine during coughing, laughing, sneezing, jogging or any other physical
activity which causes a sufficient increase in intra-abdominal pressure. This
condition varies in severity from those women who leak urine as a result of
certain sudden movements or physical activities to those who leak urine simply
upon standing up. Stress UI is caused by one of two conditions (i) urethral
hypermobility, a lack of anatomic stability caused primarily by weak surrounding
tissues, which results in the abnormal movement of the bladder neck and urethra
in response to sufficient intra-abdominal pressure or exertion; and (ii)
intrinsic sphincter deficiency, or the inability of the urinary sphincter valve
muscle to function properly due to atrophy of the urinary sphincter muscle.
Approximately 15% of stress UI cases are solely the result of intrinsic
sphincter deficiency. Urethral hypermobility is the principal cause of the
remaining 85% of stress UI cases; however, the Company believes that many of
these patients have a mix of urethral hypermobility and intrinsic sphincter
deficiency.
 
                                       24
<PAGE>   26
 
     Urge urinary incontinence. Urge UI refers to the involuntary loss of urine
due to an unexpected bladder contraction that is associated with a strong,
uncontrollable desire to urinate, often referred to as urgency. Causes of urge
UI include an overactive bladder muscle, neurologic abnormalities, such as those
caused by a stroke, and urethral instability or abnormal bladder relaxation
patterns.
 
     Mixed urinary incontinence. Mixed UI is a mixture of stress and urge UI.
 
URINARY INCONTINENCE MARKET
 
     The U.S. Department of Health and Human Services reports that approximately
13 million adults suffer from UI in the U.S., although precise figures are
uncertain because of underreporting due to the stigma associated with the
condition. The National Association for Continence estimates that approximately
31% of adults with UI suffer from stress UI, approximately 21% of adults with UI
suffer from urge UI, and approximately 30% of adults with UI suffer from mixed
UI. The U.S. Department of Health and Human Services has estimated that the
annual cost for treatment of UI in the U.S. exceeds $15 billion. This amount
includes all costs associated with the treatment of UI, including physician fees
and nursing home and long-term care costs. The Company believes that medical
devices for UI, which amounted to an estimated $250 million in sales in 1997,
represent a relatively small portion of the potential market due primarily to
the limitations of currently available devices.
 
     UI particularly affects the elderly and women. Industry sources estimate
that approximately 19% of people over 65 living in non-institutional settings
and 40% of such persons living in institutional settings suffer from UI. UI is
believed to be a primary reason for admission to long-term nursing care
facilities. In addition to being prevalent in the elderly, UI is a major women's
health concern with women accounting for approximately 85% of the estimated 13
million adults with UI in the U.S. The higher incidence of UI among women is
generally attributed to pelvic trauma during pregnancy and childbirth, menopause
and abdominal surgery. UI will continue to be a significant health care problem
in the elderly and institutionalized populations and among adult females, and
the number of individuals suffering from UI is expected to increase as the
population continues to age.
 
CURRENT TREATMENTS AND THEIR LIMITATIONS
 
     The Company views the treatment of UI at five levels of intervention: (i)
diagnosis; (ii) simple self-management through the use of products and
approaches that manage, but do not cure the condition, such as disposable or
reusable absorbents, behavioral therapy and pelvic muscle training exercises;
(iii) complex self-management through the use of products or procedures that can
be performed by the patient but require a device to be manually inserted in the
body, such as urethral and vaginal inserts and plugs; (iv) minimally invasive
treatments that can be accomplished on an outpatient basis, such as urethral
bulking agents, pharmaceuticals and Foley catheters; and (v) invasive surgery
under general anesthesia that involves suspension and sling procedures,
artificial sphincters and implantable nerve stimulation devices.
 
     Disposable or reusable absorbents. Many cases of stress and urge UI are
managed through the use of disposable adult diapers, shields and reusable
absorbent pads. These products are palliative and do not treat the causes of the
patient's UI. The cost of diapers and pads over time can be substantial and is
not covered by medical insurance, creating a continuous financial burden for the
patient. Industry sources estimate that the annual sales of disposable diapers
and pads in the U.S. constitutes a $1.0 to $2.0 billion market. In addition,
this management technique requires frequent changing of diapers and pads to
control odor. Diapers and pads are also uncomfortable and wearing them can be an
embarrassment to the patient.
 
     Behavioral therapy and pelvic muscle training exercises. Behavioral therapy
and related techniques are also used to manage UI through bladder and habit
training, pelvic muscle exercises (known as Kegel exercises) and biofeedback.
These techniques are primarily used in managing stress UI but can also be used
by persons suffering from urge UI. These therapies and techniques first teach
the patient to be aware of the group of muscles in the perineal area and to
contract them in a way that builds muscle tone around the bladder neck. These
treatments are time consuming, take several weeks or months before results are
evident, present uncertain outcomes and require strict patient compliance.
                                       25
<PAGE>   27
 
     Urethral and vaginal inserts and plugs. Urethral inserts act as expandable
stoppers to block the flow of urine when inserted in the urethra. When the
patient feels the need to urinate, these devices are either opened or removed to
allow the patient to urinate. The insertion method and the need to periodically
replace or remove these devices require a high degree of complex self-management
by the patient, which limits the usefulness of these devices to a small segment
of highly-motivated, extremely compliant patients. Potential adverse side
effects include urinary tract infections. Vaginal inserts are used to manage
stress UI by obstructing the bladder neck and urethra by applying pressure
through the neighboring vaginal cavity. These devices are frequently ineffective
in preventing leakage because it is difficult to fit patients properly and apply
sufficient pressure to eliminate the leakage of urine without causing
discomfort. Potential side effects observed with vaginal inserts include vaginal
discharge and tissue erosion.
 
     Urethral bulking agents. Bulking agents are either biologically derived or
synthetic materials designed to be injected or implanted in or near the bladder
neck to treat stress UI by increasing tissue bulk. These bulking agents decrease
the urethral opening at the sphincter and compensate for the lack of muscle tone
that is needed to offset the hydrodynamic pressure of the bladder, thus
preventing urine leakage under stress. Bulking procedures are gaining acceptance
as a method of treating certain types of stress UI as a result of the high
efficacy rates achieved in clinical trials. However, biologically-derived
bulking agents currently available have experienced problems with absorption by
the body and may require retreatments within six to twelve months. Synthetic
bulking agents currently available have experienced problems with migration
because particles may be small enough to migrate to other areas of the body such
as the brain, lungs or lymphatic system. In addition, both synthetic and
biologically-derived bulking materials are not encapsulated and cannot be
contained after injection and therefore are not easily retrievable in the event
of chronic urinary retention.
 
     Pharmaceuticals. Drug treatments can be used to manage both urge UI and
stress UI, but have demonstrated a limited efficacy, particularly in managing
stress UI. Drugs for the management of urge UI affect the contraction of the
muscle tissue of the bladder. Drugs for the management of stress UI attempt to
either affect contraction of the muscle tissue of the bladder neck or improve
the quality of the mucosal lining of the bladder neck and urethra. Drugs seldom
represent a long-term, effective solution and potential side effects include
dryness of the eyes (resulting in blurred vision) and mouth, urinary retention,
nausea, dizziness and the possibility of adverse drug interactions.
 
     Foley catheters. Foley catheters, which are typically used to assist
patients unable to urinate post-surgery, may also be used to manage UI in
hospitals and long-term care facilities. The Foley catheter is inserted through
the urethra into the bladder. Once in place, the catheter is either clamped at
the exit point from the body or connected to an external urine collection bag.
Aside from the physical and emotional discomfort experienced by patients, the
direct path from the exterior to the bladder provides a conduit for bacteria,
and often results in bladder infections.
 
     Suspension and sling procedures. Bladder neck suspension and sling
procedures involve invasive surgical intervention to elevate and stabilize the
urethra and the bladder neck in order to treat stress UI. In a bladder neck
suspension, the bladder neck and urethra are elevated to prevent urethral and
bladder neck prolapse (descent) during exertion. In a sling procedure, either an
autologous (patient tissue) or synthetic piece of material is placed under the
urethral-bladder junction, pulling it forward in a way that reinforces and
strengthens the sphincter. Surgeries of this nature are costly, delicate and
complicated procedures in which the outcome depends on a number of factors,
including the degree of severity of the patient's condition and the surgeon's
experience.
 
     Artificial sphincters. Artificial sphincters are implantable, miniature,
hydraulic medical devices consisting of an inflatable cuff placed around the
urethra and a pump and tubing required to activate the cuff. The most common
applications are for post-prostatectomy incontinence and patients with
neuropathic bladders. Artificial sphincter implantation currently requires a
major inpatient surgical procedure and hospitalization with associated
discomfort, lengthy recovery period and high expense. Initial complications that
may arise are mainly associated with post-operative infection or urethral or
bladder injury during implantation. Delayed complications include mechanical
problems such as pump malfunctioning, fluid leaks, tubing kinks and tissue
atrophy.

     Implantable Nerve Stimulation Devices. Implantable nerve stimulation
devices stimulate the nerve bundle located in the spinal column that controls
bladder activity in an attempt to reduce the bladder spasms that cause urge UI.
The only such device currently sold commercially is derived from traditional
pacemaker technology, and the implantation of the device is an open surgical
procedure which is usually performed by a urologist and assisted by a
neurosurgeon, if necessary. This device involves a lead that is attached to the
spinal column and connected to an electrical stimulation device (which contains
a battery) implanted in the abdomen. Periodically, the patient must submit to
additional surgical procedures in order to change the batteries or replace the
implanted device. Implantation of the device requires costly major invasive
surgery including exposure of the spine. In clinical testing, the device showed
efficacy in approximately 75% of patients. However, 35% of patients reported
long-term pain from the device and required additional surgery to reposition the
implant.
 
THE UROSURGE SOLUTION
 
     Stress UI solution. The Company believes that UroVive is an effective
method for treating stress UI and addresses the major problems associated with
existing treatments. UroVive is a minimally invasive system that is initially
being targeted for the treatment of stress UI caused by intrinsic sphincter
deficiency. The Company may seek to expand the targeted indications for UroVive
by conducting additional clinical trials and seeking additional regulatory
approvals.
 
     The Company believes that the following are the principal advantages of
UroVive compared to other urethral bulking agents and other approaches for
treating stress UI:
 
     -  No absorption. The membrane of the UroVive microballoon completely
        contains the hydrogel filler material, preventing loss of volume through
        absorption. In contrast, other injectibles such as collagen can be
        absorbed by the body, resulting in the potential need for retreatments
        within six to twelve months in order to maintain bulk in the urethral
        sphincter. With UroVive, long-term bulking of the urethral sphincter can
        be achieved in a single procedure.
 
     -  No migration. UroVive does not spread along tissue planes or migrate to
        other parts of the body like unencapsulated bulking agents such as
        teflon or silicone microparticles. Migration causes difficulty in
        maintaining bulk in the desired area, requiring the injection of large
        amounts of material as well as possible retreatment. Furthermore,
        migration to other parts of the body may result in the occurrence of
        unpredictable and unintended side effects.
 
     -  Ease of use and patient convenience. Placement of UroVive microballoons
        is a relatively easy procedure that takes approximately 20 minutes and
        is performed using a cystoscope, a visualization device that is commonly
        used in urinary tract procedures. In addition, UroVive is convenient for
        the patient who experiences immediate continence and who is not required
        to adhere to ongoing treatment regimens, which are necessary with
        reusable or disposable absorbents, behavioral therapy, pelvic muscle
        training exercises, pharmaceuticals and urethral and vaginal inserts and
        plugs.
 
     -  Minimally invasive procedure. The UroVive procedure is minimally
        invasive and can be performed in an outpatient or physician office
        setting under local anesthesia. Unlike suspension and sling procedures
        and artificial sphincters that may require several days of
        hospitalization, patient recovery time is minimal and hospitalization is
        not required.
 
     -  Long-term, cost-effective solution. The UroVive procedure is designed to
        provide immediate, long-term continence from a one-time treatment. As
        such, UroVive offers a cost-effective solution compared to palliative
        measures that do not restore continence, other urethral bulking agents
        that often require costly retreatments or invasive surgery.
 
     -  Retrievability. In cases of chronic urinary retention, it may be
        necessary to retrieve the urethral bulking agent. UroVive microballoons
        are retrievable transurethrally through a small incision in the urethra.
        No practical method exists for retrieving competing urethral bulking
        agents, all of which are unencapsulated.
 
                                       27
<PAGE>   29
 
     Urge UI solution. The Company believes that SANS is an effective system for
treating urge UI and addresses many of the problems with existing treatments.
SANS is a minimally invasive system that modulates bladder action through
stimulation of the afferent nerve fibers in the ankle area that lead to nerves
located in the spinal region that control bladder function.
 
     The Company believes that the following are the principal advantages of
SANS compared to the only commercially available implantable electronic nerve
stimulation device and other approaches for treating urge UI:
 
     -  Effective and less invasive solution. SANS stimulates the same nerves
        and achieves equivalent efficacy with significantly reduced invasiveness
        and risk as compared to the only commercially available implantable
        electronic nerve stimulation device, which requires an invasive
        implantation of an electrical lead in close proximity to the spinal
        column along with a battery operated electronic stimulation device in
        the abdomen. Furthermore, clinical trials indicated that 35% of patients
        treated with this spinal implant device required surgical reintervention
        due to lead migration and other complications.
 
     -  Patient comfort. Percutaneous SANS delivers electrical stimulation
        through a small diameter needle temporarily inserted in the ankle area
        and subcutaneous SANS will deliver electrical stimulation through a
        small receiver implanted in the ankle area. In contrast, the spinal
        implant system delivers electrical stimulation through an implanted
        device that is complex and bulky, which can result in patient
        discomfort.
 
     -  Cost-effectiveness. The percutaneous SANS procedure is performed in
        periodic, short visits to the doctor's office and uses a relatively
        inexpensive disposable needle and lead wire assembly. By contrast, the
        competing spinal implant entails the implantation of a costly,
        self-contained electrical stimulation device in an invasive surgical
        procedure, requiring retreatments for battery replacement and
        reintervention due to complications. In addition, subcutaneous SANS
        should enable the Company to reduce the cost of each SANS treatment by
        ultimately enabling SANS treatments to be performed at home. Unlike the
        spinal implant, SANS will not require reoperation for battery
        replacement.
 
     -  Ease of use. Both percutaneous and subcutaneous SANS procedures are
        relatively easy and will be performed in a physician office setting. The
        percutaneous SANS treatment can be performed in approximately 30 minutes
        by the urologist and implantation of the subcutaneous SANS receiver will
        be performed in a short, outpatient procedure under local anesthesia.
 
     -  Curative approach. Other than a spinal implant, few approaches exist for
        treating urge UI. SANS is designed to be a curative approach for
        treating urge UI, unlike palliative approaches such as diapers. In
        addition, SANS does not present the side-effects often associated with
        pharmaceuticals, which also may have short-term effectiveness.

PRINCIPAL PRODUCTS
 
  UROVIVE
 
     UroVive system. The UroVive system includes a delivery system, a
microballoon and a syringe filled with biocompatible hydrogel, which will be
sold in an integrated kit. The microballoons are made of cross-linked silicone
polymer and are available in various sizes depending on the amount necessary to
provide the muscular tension for continence. The hydrogel material is a
hydrophilic, or water-absorbing polymer, which has been demonstrated to be safe
when used in other devices, including contact lenses. The microballoons can be
delivered periurethrally or transurethrally.
 
     In a periurethral UroVive procedure, a cystoscope is inserted through the
urethra and used for visualization of the sphincter muscle while a catheter and
deflated microballoon are delivered directly into the sphincter muscle using a
needle and sheath. After proper needle positioning, the needle is removed, the
sheath is retracted and the deflated balloon is exposed in the tissue pocket
created in the sphincter muscle. Once inside the pocket, a syringe connected to
the catheter containing hydrogel is used to inflate the microballoon. When the
microballoon is sufficiently filled, the sheath and catheter are retracted, the
microballoon is detached, seals itself and remains in place. In a transurethral
UroVive procedure, a cystoscope is inserted in the urethra and a needle and
sheath are advanced through the working channel of the cystoscope and inserted
into the sphincter muscle, creating a small tissue pocket. The closed-end needle
is removed, leaving the sheath in place. A catheter and a deflated microballoon
are inserted through the lumen of the delivery sheath until the balloon is
positioned in the tissue pocket. As in a periurethral procedure, when the
microballoon is sufficiently filled, the microballoon is detached, seals itself
and remains in place.
 
            [SERIES OF DIAGRAMS DEMONSTRATING THE UROVIVE PROCEDURE]
 
     A typical UroVive procedure will involve the placement of three balloons
around the perimeter of the sphincter muscle to achieve closure. The procedure
can be performed in about 20 minutes in an outpatient
 
                                       30
<PAGE>   32
 
setting and is designed to immediately restore the patient to normal urinary
continence. A typical procedure using three or four microballoons is comparable
to other urethral bulking agents.
 
     UroVive clinical trials. In February 1996, the Company initiated clinical
testing of UroVive in a pilot study involving 27 women with stress UI due to
intrinsic sphincter deficiency. The study was completed in February 1997. The
Company's clinical investigators have been following the progress of these
patients, and the Company currently has one to two year follow-up data. Results
indicate a 90% efficacy rate for female patients with stress UI due to intrinsic
sphincter deficiency for which the Company has 18-month follow-up data. The
UroVive treatment is considered effective if the patient is either dry
(continent) or achieves an improvement on a scale, known as the Stamey Scale,
which is used to measure the grade and severity of UI symptoms.
 
     The Company received FDA approval to enroll up to 216 patients at up to 10
U.S. sites in a pivotal clinical trial of UroVive for the treatment of females
with stress UI caused by intrinsic sphincter deficiency. This is a controlled,
randomized study in which two-thirds of the patients will be randomized into the
UroVive treated group and one-third will be randomized into a control group. The
control group patients will be treated with a commercially available collagen
urethral bulking agent. As of March 31, 1998, approximately 100 patients had
been enrolled with 70 patients in the UroVive treated group and 30 patients in
the control group. This clinical trial is designed to obtain data to support a
PMA application for UroVive, which the Company expects to submit in mid-1999.
 
     The Company is conducting clinical trials for the treatment of other UI
indications using UroVive. For example, another indication in clinical trials
involves males who experience stress UI after undergoing a radical
prostatectomy. The Company is currently in the pilot phase of this trial in
which 10 patients will be treated. The Company plans to pursue regulatory
approvals for these other indications to expand UroVive's application.
 
  SANS
 
     Percutaneous SANS. The percutaneous SANS system consists of a generator
that delivers electrical impulses through a small disposable needle and lead
wire assembly. In a SANS procedure, the physician temporarily inserts the needle
into the proper location in the ankle area. After the lead wire and electrode
are attached, the SANS device is turned on and amplitude is slowly increased
until the patient's large toe starts to curl or the toe digits fan out,
indicating proximity to the nerve bundle. Amplitude is then reduced slightly and
the patient receives intermittent electrical pulses for approximately 30 minutes
per visit. The treatment is repeated weekly in a physician office setting and
after approximately 10 weeks, the physician can assess patient progress. If
improvement is significant, the physician may place the patient on a regimen
requiring less frequent treatments. SANS was originally developed by Dr.
Marshall Stoller, a leading urologist at UCSF School of Medicine.
 
     Percutaneous SANS clinical trials. Clinical studies to date, encompassing
90 patients with average follow-up in excess of two-years, demonstrated an 80%
efficacy rate in the treatment of urinary urgency, frequency and pelvic pain
with no complications in over 1,000 treatment procedures. Efficacy is defined as
an at least 50% improvement in one or more of a patient's urge UI symptoms.
 
     In the first quarter of 1998, the Company received FDA approval to enroll
up to 60 patients at up to four sites in a nonrandomized, pivotal clinical
trial. In this study, urgency and frequency will be used as benchmarks for
measuring patient progress over a period of at least 10 weeks and up to one
year. This clinical trial is designed to obtain data to support a PMA
application for percutaneous SANS, which the Company expects to submit in early
1999.
 
     Subcutaneous SANS. To ultimately facilitate in-home use and enhance patient
convenience, the Company is developing a second generation, subcutaneous SANS
that involves the permanent implant of a small, thumbtack-shaped receiver near
the patient's ankle, eliminating the need for the use of a needle with each
treatment. The patient may then visit a physician weekly to receive the
electrical stimulus or perform the treatment on himself or herself at home.
Because the permanent implant is simply a receiver for a magnetic
 
                                       31
<PAGE>   33
 
pulse, it will not require batteries and the patient will not have to undergo
subsequent implants for battery replacement.
 
     Subcutaneous SANS clinical status. The Company is currently conducting
preclinical animal studies of subcutaneous SANS and, depending upon the outcome
of these studies, expects to file an IDE for FDA approval to conduct pilot and
pivotal clinical trials in late 1998.
 
OTHER PRODUCTS
 
  SpiraStent and FilaStent
 
     SpiraStent and FilaStent are ureteral stents designed to facilitate urine
flow and the passage of kidney stone fragments generated by lithotripsy or other
procedures. Approximately 200,000 lithotripsy procedures are performed annually
in the U.S. for kidney stone removal. Currently available ureteral stents are
simple tubes with intermittent side holes along their length. To date, the
principal purpose of ureteral stents has been to dilate the ureter to allow
urine passage around the stone fragments. Stones typically do not pass through
the center lumen of the stent or through the side holes, but will move along the
outside wall of the stent. With conventional smooth walled stents, the natural
peristaltic motion of the ureter causes stone fragments to oscillate back and
forth along the outer wall of the stent, resulting in slow downward progression.
SpiraStent is differentiated by its extrusion screw-like shape, which is
designed to overcome the problem of slow movement by allowing stones to pass
down the channel of the screw as natural peristalsis and urine flow occur. The
ability of SpiraStent to provide improved expulsion of stone fragments has been
demonstrated in preclinical animal trials.
 
     FilaStent is a smooth ureteral stent with an embedded high strength
filament within its wall designed to facilitate post-encrustation removal of the
device. In some cases, ureteral stents may be left in place for 30 days or
longer, particularly when used to provide a conduit for urine passage after
certain types of kidney and ureteral surgeries. As a result, stents may become
encrusted and brittle, resulting in breakage during removal. With conventional
stents, encrustation and breakage can lead to the need for surgical intervention
to remove the fractured stent. With FilaStent, in the event of encrustation and
fracture of the stent, the fragments would remain bonded to the filament and be
retrieved upon removal of the stent.
 
  AcuTrainer
 
     AcuTrainer is a hand-held, battery-operated device that facilitates
behavior modification by chiming or vibrating at increasing time intervals to
prompt urge UI patients to urinate. Patients with urge UI often attempt to keep
their bladder as empty as possible at all times to avoid accidental urination.
However, the more frequently they urinate, the more frequently they get the urge
to urinate. Bladder retraining, when used as a first-line treatment modality,
has been shown to non-invasively improve or correct the condition in many
patients. AcuTrainer circumvents the need for the patient to keep cumbersome
voiding diaries and provides the clinician with an effective tool for monitoring
several parameters pertaining to patient progress. After urinating, the patient
presses a button which resets the internal clock of the device. When a patient
has an incontinence or leak episode, they will press another button, registering
this event in the device memory. The physician can choose the initial time
interval, and the device automatically advances the patient to the next time
interval only after a specific success rate is achieved. The physician may
access AcuTrainer memory to determine patient compliance, frequency of
urination, nocturia (urinating during sleep) and urge UI episodes.
 
  UroTherm
 
     The Company is developing UroTherm, a device for warming irrigation fluids
used in surgical procedures to treat benign prostatic hyperplasia ("BPH"),
laparoscopic surgical procedures and other types of gynecological and urological
procedures. Approximately 200,000 BPH surgical procedures are performed annually
in the U.S.
 
                                       32
<PAGE>   34
 
     During a typical laparoscopic or BPH surgical procedure, urologists may use
up to 30 liters of irrigation solution such as saline, which is warmed to body
temperature. Studies indicate that warmed irrigation fluid for urological
applications reduces infections, speeds healing and shortens hospital stays. The
current practice of heating bags of fluid is to place them in an oven and
replenish them from time to time as they are used. This process is inconvenient
and inefficient. To address this problem, the Company is developing UroTherm, a
system which will heat the solution in-line, eliminating the need to
continuously heat and replenish bags. UroTherm will consist of a small heating
unit that can be mounted onto an IV pole. The hardware unit will provide an
actual irrigation fluid temperature readout and an advanced electronic
temperature control system. The unit will consist of a plastic cartridge that is
disposable and will be included as part of the TURP infusion set. As the
irrigation solution flows through the disposable unit, it is warmed to body
temperature. The Company has submitted a 510(k) clearance application to the FDA
for UroTherm.
 
  Kidney Stone Grasper
 
     The Company is developing a kidney stone grasping device for removing
multiple small and large kidney stones or stone fragments from the ureter or
bladder. Current kidney stone graspers are typically either wire baskets or
pincers. These devices have sharp cutting edges, which can be painful and
traumatic to the patient. In addition, they typically can only grasp one stone
at a time. The Company's kidney stone grasper is designed with a soft,
collapsible polymeric net that can be opened in the ureter. Multiple stone
fragments can be snared as the net collapses around them and can then be
withdrawn through the ureteral catheter, minimizing trauma to the patient. The
Company plans to submit a 510(k) clearance application for the kidney stone
grasper in late 1998.
 
  Demineralized Bone Paste
 
     The Company is developing an injectable demineralized bone paste for
treatment of VUR in infants and children. VUR is a condition caused by an
abnormal interface between the ureter and the bladder resulting in backflow or
"reflux" of urine from the bladder to the kidney when the child urinates. VUR
can cause chronic urinary tract infections and necrosis of the kidney. Severe
cases of VUR must be treated with invasive and expensive surgery. The Company's
demineralized bone paste, which has been shown in preclinical trials
encompassing two years of data to be biocompatible, nonimmunogenic, nonmigratory
and nonresorbable, is injected at the junction of the bladder and uretero in a
minimally invasive outpatient procedure to restore proper functioning of the
child's urinary system. In January 1998, the Company received IDE approval to
commence a pilot study for treatment of VUR. This study is scheduled to begin in
July of 1998 and is expected to be followed by a non-randomized pivotal trial.
The development of this product is being partially funded by Child Healthcare
Corporation of America. The Company also intends to explore the use of the
demineralized bone paste in other UI indications, including the treatment of
urethral hypermobility.
 
  Urethral Pressure Catheter
 
     Urethral or sphincter pressure is an important factor in diagnosing
intrinsic sphincter deficiency. Establishing whether a patient's stress UI is
caused by intrinsic sphincter deficiency or another category of stress UI is
important because the treatments are specific to the indicated type of UI.
 
     The current methods of testing for stress UI caused by intrinsic sphincter
deficiency consist of a video urodynamic profile procedure that costs
approximately $1,000 or use of a balloon catheter such as a Foley catheter that
is inflated partially in the bladder and then pulled past the sphincter muscle
to measure sphincter resistance. The urodynamic profile method is expensive and
the latter method can be inaccurate due to inconsistencies associated with the
pressure transducers in the balloon.
 
     The Company's urethral pressure catheter will consist of a catheter with a
custom-designed tip. The tip has the appearance of an inverted umbrella. The
umbrella is folded shut and advanced into the bladder "handle first." The
umbrella tip can be opened to various degrees, thereby tailoring the
circumference of the device. After the umbrella tip is opened, the catheter is
retracted through the urethra. Pull force as a function of umbrella opening
diameter and urethral distance are measured. A correlation between pull force
and
 
                                       33
<PAGE>   35
 
intrinsic sphincter strength can be generated to obtain a diagnosis of intrinsic
sphincter deficiency. The Company's urethral pressure catheter is designed to
provide diagnostic accuracy comparable to urodynamic profiling at significantly
reduced cost. The Company expects to have completed development of a functional
prototype by late 1998.
 
SALES AND MARKETING
 
     The Company is marketing UroVive, percutaneous SANS, SpiraStent, FilaStent
and AcuTrainer in Europe and other international markets and is recognizing
revenues from these efforts in the second quarter of 1998. The Company's current
distributors cover 14 European countries, South Korea, Australia and Japan. Each
distributor has non-exclusive rights in its designated territory. The Company
distributes its products internationally through distributors on a
country-by-country basis to access such distributors' established networks and
specialized expertise regarding the healthcare system, including reimbursement
practices, in their respective markets. In addition, the Company has established
clinical research relationships with leading international urologists. The
Company believes that its country-specific approach will accelerate sales
growth, provide comprehensive geographic market coverage and enable the Company
to access particular markets and customers.
 
     The Company is also marketing SpiraStent and AcuTrainer in the U.S. and
intends to commence marketing of UroVive and SANS in the U.S. upon receipt of
PMA approval. The Company's U.S. direct sales and marketing staff currently
consists of six sales and marketing executives and two telemarketers. The
Company has retained U.S. marketing rights to its products and plans to continue
expanding its direct sales effort as regulatory approvals and clearances are
received. Industry sources estimate that there are approximately 8,000
urologists and 800 urogynecologists in the U.S. to which the Company could
market its products. The Company believes that this relatively small number of
physicians can initially be served by a sales force of fewer than 20 people. See
"Risk Factors -- Limited Marketing and Sales Capabilities."
 
MANUFACTURING
 
     The Company is currently manufacturing AcuTrainer and is scaling up its
manufacturing facilities for the clinical and early commercial production of its
other products. The Company recently leased an additional 11,500 square foot
space adjacent to the Company's headquarters in order to meet its anticipated
supply requirements. Historically, the Company has relied on contract
manufacturers to produce development prototypes and products for clinical
trials. However, as products receive regulatory clearance, the Company intends
to manufacture its own products, beginning with the assembly or manufacture of
percutaneous SANS hardware and disposables, UroVive kits, SpiraStent and
FilaStent kits and the preparation of demineralized bone paste. The Company is
currently in the process of building out its facility which is expected to be
completed in July 1998. This facility will contain a class 10,000 clean room.
See "Risk Factors -- Limited Manufacturing Experience."
 
     The Company purchases raw materials and components used in its products
from various suppliers. A contract supplier provides the Company with the
microballoons used in the UroVive system under a mutually exclusive supply
agreement executed in April 1995. The agreement expires in April 2000 subject to
an automatic two-year extension if the Company does not receive the FDA's
approval of the Company's PMA application for UroVive by April 1999, which
approval the Company does not expect to receive by such date. In addition to
UroVive balloons, certain materials and components are currently purchased by
the Company from single sources. To date, these materials have generally been
readily available and the Company has not experienced supply shortages. See
"Risk Factors -- Dependence Upon Key Suppliers."
 
     The Company is also required to register as a medical device manufacturer
with the FDA and to list its products with the FDA. Furthermore, prior to
approval of a PMA application, the Company's facilities, procedures and
practices, and the facilities, procedures and practices of its third-party
manufacturers, will be subject to a preapproval inspection by the FDA. In
addition, if the Company wishes to significantly modify its manufacturing
processes or change the supplier of a critical component, additional approvals
will be required from the FDA before the change can be implemented. The Company
has not yet undergone an FDA QSR
 
                                       34
<PAGE>   36
 
inspection of its facilities, but may undergo such an inspection before or after
submission of its initial PMA application. See "Risk Factors -- Government
Regulation."
 
RESEARCH AND DEVELOPMENT
 
     The Company believes that its future success will depend in large part upon
its ability to enhance its existing products and to develop other new products.
Accordingly, the Company intends to continue to devote significant funds and
efforts to research and development. The Company currently employs 17
individuals on a full-time basis and five individuals on a part-time basis for
its research and development and manufacturing efforts, including five
individuals with advanced degrees.
 
     To the extent that the Company's medical advisors develop new products
which the Company believes represent attractive opportunities, the Company will
seek to negotiate licenses to the technology related to such products.
 
     For the years ended December 31, 1995, 1996 and 1997, the Company's
research and development expenses were $0.8 million, $1.9 million and $3.6
million, respectively.
 
PATENTS AND PROPRIETARY RIGHTS
 
     Because of the substantial length of time and expense associated with
bringing new products through the development and regulatory approval processes
in order to reach the marketplace, the medical products industry places
considerable importance on obtaining patent and trade secret protection for new
technologies, products and processes. Accordingly, the Company's strategy
regarding the protection of its proprietary rights and innovations is to seek
patents on those portions of its technology that it believes are patentable and
that provide a competitive advantage and to protect as trade secrets other
confidential and proprietary information.
 
     The Company has received, licensed or has obtained an option or right to
license 10 issued or allowed U.S. patents and has five pending U.S. patent
applications. The Company or its licensors have obtained or applied for
corresponding patents for certain of these U.S. patents and applications in a
limited number of foreign countries. These patent rights relate to UroVive,
SANS, AcuTrainer, SpiraStent, FilaStent, UroTherm, the kidney stone grasper,
demineralized bone paste and the urethral pressure catheter. The issued U.S.
patents have expiration dates ranging from 2009 to 2015.
 
     Patents and patent applications related to the Company's products are
either held directly by the Company or licensed from others. Much of the
original technology for the Company's products other than FilaStent and UroTherm
is licensed from others. The Company has developed improvements to the licensed
technologies related to UroVive and has filed additional patent applications to
broaden the coverage of existing patents for such improvements. See "Risk
Factors -- Dependence on Patents and Proprietary Technology."
 
     The Company has licensed technologies relating to UroVive, SANS,
SpiraStent, AcuTrainer, the kidney stone grasper, demineralized bone paste and
the urethral pressure catheter. The Company holds an exclusive worldwide right
and license to the technologies underlying UroVive, subject to a royalty-free,
nonexclusive license granted to the U.S. government (for patents developed with
U. S. government funding) and a royalty-free, nonexclusive, irrevocable license
retained by the licensor to employ the licensed technologies and processes for
research purposes only. The Company has also obtained an exclusive license to
all U. S. and foreign patents and patent applications related to the technology
underlying SANS, as well as the right to issue sublicenses to third parties in
regard to SANS-related patents. The Company has also obtained similar licenses
related to technologies underlying SpiraStent and the kidney stone grasper from
the same licensor for SANS. All of such licenses for SANS, SpiraStent and the
kidney stone grasper are subject to the right of the licensor to use the
technologies for educational and research purposes. The Company also holds an
exclusive, worldwide license to and right to sublicense AcuTrainer as well as a
right of first refusal to any future intellectual property or patent rights held
by the AcuTrainer licensor. The Company also has exclusive, worldwide licenses
to and the right to grant sublicenses to demineralized bone paste (for
urological applications) and the urethral pressure catheter, subject to rights
held by the U. S. government and the licensors. All of the licenses generally
remain in effect for the term of the underlying patents, unless earlier
 
                                       35
<PAGE>   37
 
terminated by the Company, upon the Company's breach or operation of law. For a
discussion of royalties payable under these licenses, see "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Overview" and the Company's financial statements and notes
thereto.
 
     To date, no claims have been brought against the Company alleging that its
technology or products infringe intellectual property rights of others. However,
there can be no assurance that such claims will no be brought against the
Company in the future or that any such claims will not be successful. See "Risk
Factors -- Dependence on Patents and Proprietary Technology."
 
COMPETITION AND TECHNOLOGICAL CHANGE
 
     The medical device industry, including in particular the UI product
industry, is highly competitive. The Company believes that primary competitive
factors include the level of physician and consumer awareness and acceptance of
available treatment methods, product efficacy, consistency of product quality
and delivery, price, technical capability and the training of health care
professionals and consumers in the use of available treatment methods. The
Company's ability to compete in this industry will also be affected by its
product development capabilities and innovation, its ability to obtain required
regulatory clearances, its ability to protect the proprietary technology
included in its products, its manufacturing and marketing capabilities and its
ability to attract and retain skilled employees.
 
     C.R. Bard, Inc. sells the only urethral bulking agent currently sold
commercially in the U.S. and Medtronic, Inc. sells the only commercially
available implantable electronic nerve stimulation device for urge UI. Current
major competitors who compete in the urethral bulking agent market include C.R.
Bard, Inc., Uroplasty, Inc., Advanced UroScience, Inc., BioMatrix, Inc. and
Mentor Corporation. Current major competitors who compete in the stent market
include Boston Scientific Corporation, Circon Corporation and Cook Incorporated.
 
     The Company's competitors may have greater experience in developing
products, conducting clinical trials, obtaining regulatory approvals, and
manufacturing and marketing products than the Company. Certain of these
competitors may obtain patent protection, approval or clearance by the FDA or
foreign countries or product commercialization earlier than the Company, any of
which could materially adversely affect the Company. Furthermore, if the Company
commences significant commercial sales of its products, it will also be
competing with respect to manufacturing efficiency and marketing capabilities,
areas in which it currently has limited experience. See "Risk
Factors -- Competition."
 
     Other recently developed technologies or procedures are, or may in the
future be, the basis of competitive products. There can be no assurance that the
Company's current competitors or other parties will not succeed in developing
alternative technologies and products that are more effective, easier to use or
more economical than those which have or are being developed by the Company or
that would render the Company's technology and products obsolete and
non-competitive in these fields. In such event, the Company's business,
financial condition and results of operations could be materially adversely
affected.
 
GOVERNMENT REGULATION
 
  United States
 
     The Company's products and its research and development activities are
subject to stringent regulation by numerous governmental authorities,
principally the FDA and corresponding state and foreign regulatory agencies. The
Federal Food, Drug, and Cosmetic Act (the "FDC Act"), as amended, the
regulations promulgated thereunder, and other federal and state statutes and
regulations, govern, among other things, the preclinical and clinical testing,
design, manufacture, safety, efficacy, labeling, storage, record keeping,
advertising and promotion of medical devices.
 
     In the U.S., medical devices are classified into three different classes,
class I, II and III, on the basis of controls deemed necessary to reasonably
ensure the safety and effectiveness of the device. Class I devices are subject
to general controls (e.g., labeling, premarket notification and adherence to
FDA's QSRs) and class II
 
                                       36
<PAGE>   38
 
devices are subject to general and special controls (e.g., performance
standards, postmarket surveillance, patient registries, and FDA guidelines).
Generally, class III devices are those which must receive premarket approval by
the FDA to ensure their safety and effectiveness (e.g., life-sustaining,
life-supporting and implantable devices, or new devices which have been found
not to be substantially equivalent to legally marketed devices).
 
     Percutaneous SANS is a class II medical device that requires PMA approval
prior to marketing in the U.S. UroVive, subcutaneous SANS and demineralized bone
paste are class III devices that require PMA approval prior to marketing in the
U.S. SpiraStent, FilaStent, AcuTrainer, UroTherm, the kidney stone grasper and
the urethral pressure catheter are eligible for clearance under the 510(k)
premarket notification process.
 
     Generally, before a new medical device can be marketed, marketing clearance
must be obtained through a 510(k) premarket notification or approval of a PMA
application. A 510(k) clearance will typically be granted by the FDA if it can
be established that the device is substantially equivalent to a "predicate
device," which is a legally marketed class I or II device or a class III device
for which the FDA has not called for PMAs. The FDA has been requiring an
increasingly rigorous demonstration of substantial equivalence and this may
include a requirement to submit human clinical trial data. It generally takes
four to twelve months from the date of a 510(k) submission to obtain clearance,
but it may take longer. The Company made its 510(k) submission for FilaStent in
March 1998 and for UroTherm in November 1996.
 
     The FDA may determine that a medical device is not substantially equivalent
to a predicate device, or that additional information is needed before a
substantial equivalence determination can be made. A "not substantially
equivalent" determination, or a request for additional information, could
prevent or delay the market introduction of new products that fall into this
category. For any devices that are cleared through the 510(k) process,
modifications or enhancements that could significantly affect the safety or
effectiveness, or that constitute a major change in the intended use of the
device, will require new 510(k) clearances.
 
     A PMA application must be submitted if a proposed device is not
substantially equivalent to a legally marketed class I or class II device, or if
it is a preamendment class III device for which the FDA has called for PMAs. A
PMA application must be supported by valid scientific evidence to demonstrate
the safety and effectiveness of the device, typically including the results of
clinical trials, bench tests, and laboratory and animal studies. The PMA must
also contain a complete description of the device and its components, and a
detailed description of the methods, facilities and controls used to manufacture
the device. In addition, the submission must include the proposed labeling,
advertising, and any training materials. The PMA process can be expensive,
uncertain and lengthy, and a number of devices for which FDA approval has been
sought by other companies have never been approved for marketing. The Company
has not submitted a PMA application for UroVive, the SANS devices or
demineralized bone paste.
 
     Upon receipt of a PMA application, the FDA makes a threshold determination
as to whether the application is sufficiently complete to permit a substantive
review. If the FDA determines that the PMA application is sufficiently complete
to permit a substantive review, the FDA will accept the application for filing.
Once the submission is accepted for filing, the FDA begins an in-depth review of
the PMA. The FDA review of a PMA application generally takes one to three years
from the date the PMA is accepted for filing, but may take significantly longer.
The review time is often significantly extended by the FDA asking for more
information or clarification of information already provided in the submission.
During the review period, an advisory committee, typically a panel of
clinicians, may be convened to review and evaluate the application and provide a
recommendation to the FDA as to whether the device should be approved. The FDA
accords substantial weight to the recommendation but is not bound by it. Toward
the end of the PMA review process, the FDA generally will conduct an inspection
of the manufacturer's facilities to ensure compliance with applicable QSRs,
which include elaborate testing, control documentation and other quality
assurance procedures. The Company has not yet undergone an FDA QSR inspection
and does not anticipate that it will undergo such an inspection until after
filing of its initial PMA application. Separate preapproval inspections are
required for each PMA application.
 
                                       37
<PAGE>   39
 
     If FDA evaluations of both the PMA application and the manufacturing
facilities are favorable, the FDA may issue either an approval letter or an
approvable letter, which usually contains a number of conditions that must be
met in order to secure final approval of the PMA. When and if those conditions
have been fulfilled to the satisfaction of the FDA, the agency will issue a PMA
approval letter, authorizing marketing of the device for certain indications. If
the FDA's evaluation of the PMA application or manufacturing facilities is not
favorable, the FDA will deny approval of the PMA application or issue a
"complete response" letter. The FDA may determine that additional clinical
trials are necessary, in which case the PMA may be delayed for one or more years
while additional clinical trials are conducted and submitted in an amendment to
the PMA. Modifications to a device that is the subject of an approved PMA, its
intended use or manufacturing process may require approval by the FDA of PMA
supplements or new PMAs. Supplements to a PMA often require the submission of
the same type of information required for an initial PMA, except that the
supplement is generally limited to that information needed to support the
proposed change from the product covered by the original PMA.
 
     If human clinical trials of a device are required, either for a 510(k)
submission or a PMA application, and the device presents a "significant risk,"
the sponsor of the trial (usually the manufacturer or the distributor of the
device) must file an investigational device exemption ("IDE") application prior
to commencing human clinical trials. The Company has received an IDE for
UroVive, percutaneous SANS and the demineralized bone paste and expects to file
an IDE application for subcutaneous SANS. The IDE application must be supported
by data, typically including the results of animal and laboratory testing. If
the IDE application is approved by the FDA and one or more appropriate
Institutional Review Boards ("IRBs"), human clinical trials may begin at a
specific number of investigational sites with a specific number of patients, as
approved by the FDA. If the device presents a "nonsignificant risk" to the
patient, a sponsor may begin the clinical trial after obtaining approval for the
study by two or more appropriate IRBs without the need for FDA approval.
Submission of an IDE does not give assurance that FDA will approve the IDE and,
if it is approved, there can be no assurance that FDA will determine that the
data derived from the studies support the safety and efficacy of the device or
warrant the continuation of clinical trials. Sponsors of clinical trials are
permitted to sell investigational devices distributed in the course of the study
provided such compensation does not exceed recovery of the costs of manufacture,
research, development and handling. An IDE supplement must be submitted to and
approved by the FDA before a sponsor or investigator may make a change to the
investigational plan that may affect its scientific soundness or the rights,
safety or welfare of human subjects.
 
     If clearance or approval is obtained, any device manufactured or
distributed by the Company will be subject to pervasive and continuing
regulation by the FDA. The Company will be subject to routine inspection by the
FDA and other international regulatory authorities and will have to comply with
the host of regulatory requirements that usually apply to medical devices
marketed in the U.S., including labeling regulations, QSR requirements, the
Medical Device Reporting ("MDR") regulation (which requires a manufacturer to
report to the FDA certain types of adverse events involving its products), and
the FDA's general prohibitions against promoting products for unapproved or
"off-label" uses.
 
     If the FDA believes that a company is not in compliance with law, it can
institute proceedings to detain or seize products, issue a recall, enjoin future
violations and assess civil and criminal penalties against the Company, its
officers and its employees. Failure to comply with the regulatory requirements
could have a material adverse effect on the Company's business, financial
condition and results of operations. In addition, regulations regarding the
manufacture and sale of the Company's products are subject to change. The
Company cannot predict the effect, if any, that such changes might have on its
business, financial condition and results of operations.
 
     Among the requirements for product approval is the requirement that the
prospective manufacturer conform to the FDA's Quality Standard Regulation
("QSR") requirements, which incorporate the FDA's former GMP regulations. QSR
addresses the design and other applicable controls, methods, facilities and
quality assurance controls used in the manufacture, packaging, storing and
installation of products. In complying with the QSR regulations, manufacturers
must continue to expend time, money and effort in product, record keeping and
quality control to assure that the product meets applicable specifications and
other requirements. The FDA periodically inspects device and drug manufacturing
facilities in the U.S. in
                                       38
<PAGE>   40
 
order to assure compliance with applicable QSR requirements. Failure of the
Company to comply with the QSR regulations or other FDA regulatory requirements
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
     The President recently signed into law the Food and Drug Administration
Modernization Act of 1997. This legislation makes changes to the device
provisions of the FDA Act and other provisions in the Act affecting the
regulation of devices. Among other things, the changes will affect the 510(k)
and PMA processes, and also will affect device standards and data requirement
procedures relating to humanitarian and breakthrough devices, tracking and
postmarket surveillance, accredited third-party review, and the dissemination of
off-label information. The Company cannot predict how or when these changes will
be implemented or what effect the change will have on the regulation of the
Company's products.
 
  International
 
     In order for the Company and its distributors to market its products in
Europe and other foreign countries, the Company and/or its distributors must
obtain required regulatory approvals and comply with extensive regulations
governing safety, quality and manufacturing processes. These regulations vary
significantly from country to country and with respect to the nature of the
particular medical device. The time required to obtain approval to market the
Company's products may be longer or shorter than that required in the U.S., and
requirements for licensing may differ from FDA requirements.
 
     In order to market the Company's products in the member countries of the
European Union, the Company will be required to comply with the Medical Devices
Directive ("MDD") and obtain CE mark certification. CE mark certification is an
international symbol of adherence to quality assurance standards and compliance
with applicable European medical device directives. Under the system established
by the MDD, all medical devices other than active implants and in-vitro
diagnostic products must qualify for CE marking by June 14, 1998. In August
1997, the Company was granted ISO 9001 certification for its Coralville, Iowa
facility. The ISO 9001 designation, and certain other certifications received by
UroSurge under the auspices of a notified body designated under the MDD, allows
UroSurge to self-certify its products for the CE mark, other than permanent
implantables such as the subcutaneous SANS, which will require a separate CE
mark application through a designated notified body.
 
     In order to sell a medical device in Japan, a company must obtain
regulatory approval from the Japanese Ministry of Health ("MOH"). UroSurge is
currently negotiating a consulting agreement with a contract research
organization to begin the registration process for UroVive. AcuTrainer is
currently being sold in Japan and does not require registration with the MOH.
 
THIRD-PARTY REIMBURSEMENT
 
     Reimbursement and health care payment systems in international markets vary
significantly by country. In connection with international product
introductions, the Company may be required to seek international reimbursement
approvals. If required, there can be no assurance that any such approvals will
be obtained in a timely manner, or at all, and failure to receive such
international reimbursement approvals could have an adverse effect on market
acceptance of the Company's products in the international markets in which such
approvals are sought.
 
     In the U.S., health care providers, such as hospitals and physicians, that
purchase medical devices such as the Company's products, generally rely on
third-party payors, principally federal Medicare, state Medicaid and private
health insurance plans, to reimburse all or part of the cost of the treatment.
In the U.S., third-party reimbursement is generally available for surgical
procedures and minimally invasive treatments for UI but generally is unavailable
for patient management products such as diapers and pads.
 
     In the U.S. and certain other countries, third-party reimbursement is
currently generally available for certain bulking agents for UI. The Medicare
reimbursement rate for commercially available injectable bulking agents is
currently approximately $300 per two and one-half milliliter syringe. The
Company believes that typically three to five syringes of such bulking agents
are used during an injection procedure. However, there is
 
                                       39

no uniform policy for such reimbursement and there is no assurance UroVive will
receive the same level of reimbursement, if any. In the U.S. and certain other
countries, third-party reimbursement is currently generally available for
SpiraStent, FilaStent and the kidney stone retriever as they represent
improvements on products that are currently being sold and reimbursed. In the
U.S., reimbursement has been available from certain private payors and from
Medicare for implantable nerve stimulation devices. Accordingly, the Company
believes that reimbursement may become available for the Company's SANS devices
following regulatory approval, subject to the Company's ability to demonstrate
the cost-effectiveness and clinical utility of such products to third-party
payors. The availability of third-party reimbursement for its products or
competitors' products and continuing efforts to reduce the costs of health care
by decreasing reimbursement rates may reduce the price received by the Company
for its products or the ability of the Company's products to gain market
acceptance.
 
     Reimbursement for the Company's products and procedures employing such
products in the U.S. will be dependent on the Company's ability to obtain FDA
clearances and approvals to market products in the U.S. and on the Company's
ability to demonstrate the clinical utility and cost-effectiveness of its
products through clinical trials, peer reviewed articles in medical journals and
long-term follow-up data regarding the efficacy of its products. The Company
intends to work with managed care organizations to explore the possibility of
reimbursement for the use of its products in the U.S. Any such reimbursement is
likely to be variable among third-party payors. See "Risk Factors -- Uncertainty
Relating to Third-Party Reimbursement."
 
EMPLOYEES
 
     As of March 31, 1998, the Company employed 34 persons. Of these employees,
22 are in research and development and manufacturing, nine are in sales and
marketing and three are in finance and administration and other business
functions. None of the Company's current employees is represented by a labor
union or is the subject of a collective bargaining agreement. The Company
believes that it maintains good relations with its employees.
 
PRODUCT LIABILITY
 
     Although the Company has not been the subject of any product liability
litigation to date, the medical products industry is subject to substantial
litigation, and the Company, as a manufacturer of a medical products to be used
in the body, faces an inherent business risk of exposure to product liability
claims in the event that the use of its products is alleged to have resulted in
adverse effects to a patient. The Company currently has product liability
insurance with certain coverage limitations. There can be no assurance that the
Company's existing insurance coverage limits are adequate to protect the Company
from any liabilities which it might incur in connection with clinical trials or
the commercialization of its products. There can be no assurance that liability
claims will not exceed coverage limits. Such insurance is expensive and in the
future may not be available on acceptable terms, if at all. Furthermore, the
Company does not expect to be able to obtain insurance covering its costs and
losses as a result of any recall of its products due to alleged defects, whether
such recall is instituted by the Company or required by a regulatory agency. A
product liability claim, recall or other claim with respect to uninsured
liabilities or in excess of insured liabilities could have a material adverse
effect on the business, financial condition and results of operations of the
Company. See "Risk Factors -- Product Liability Risk; Limited Insurance
Coverage."
 
FACILITIES
 
     The Company's principal operations are conducted in Coralville, Iowa, in an
approximately 10,000 square foot facility. This facility serves as the site for
the Company's corporate headquarters. In addition, the Company occupies an
approximately 11,500 square foot manufacturing facility next to its corporate
headquarters. The Company is in the process of building out its manufacturing
facility and expects to be completed by July 1998. Both facilities are occupied
under a triple-net lease which expires in 2000. The Company has the option of
renewing the lease on both buildings for an additional five-year period. The
 
                                       40
<PAGE>   42
 
Company believes that these facilities are sufficient to meet the Company's
requirements through at least the next several years.
 
LEGAL PROCEEDINGS
 
     The Company is not currently a party to any material pending legal
proceedings.

BOARD COMPOSITION
 
     The Company currently has five directors. In accordance with the terms of
the Company's Restated Certificate of Incorporation, effective upon the closing
of this offering, the terms of office of the Board of Directors will be divided
into three classes: Class I, whose term will expire at the annual meeting of
stockholders to be held at the annual meeting of stockholders to be held in
1999; Class II, whose term will expire at the annual meeting of stockholders to
be held in 2000; and Class III, whose term will expire at the annual meeting of
stockholders to be held in 2001. The Class I directors are Robert E. Curry,
Ph.D. and Joseph F. Lovett, the Class II director is David H. Maupin and the
Class III directors are Dick P. Allen and William E. Engbers.
 
     At each annual meeting of stockholders after the initial classification,
the successors to directors whose term will then expire will be elected to serve
from the time of election and qualification until the third annual meeting
following election. In addition, the Company's Bylaws provide that the
authorized number of directors may be changed only by resolution of the Board of
Directors. Any additional directorships resulting from an increase in the number
of directors will be distributed among the three classes so that, as nearly as
possible, each class will consist of one-third of the directors. This
classification of the Board of Directors may have the effect of delaying or
preventing changes in control or management of the Company.
 
     Each officer is elected by and serves at the discretion of the Board of
Directors. Each of the Company's officers and directors, other than its
nonemployee directors, devote such time to the affairs of the Company as is
necessary to discharge their duties. There are no family relationships among any
of the directors, officers or key employees of the Company.
 
BOARD COMMITTEES
 
     The Audit Committee of the Board of Directors (consisting of Dick P. Allen
and Joseph F. Lovett) reviews the internal accounting procedures of the Company
and consults with and reviews the services provided by the Company's independent
accountants. The Compensation Committee of the Board of Directors (consisting of
Robert E. Curry, Ph.D. and William E. Engbers) reviews and recommends to the
Board the compensation and benefits of all executive officers of the Company and
establishes and reviews general policies relating to compensation and benefits
of employees of the Company. The Board does not have a nominating committee or
any committee currently performing the functions of a nominating committee.
 
DIRECTOR COMPENSATION
 
     The Company does not pay its directors for attending meetings of the Board
of Directors or for serving on Committees of the Board of Directors. Directors
are reimbursed for their out-of-pocket expenses incurred in attending meetings.
From time to time, certain directors of the Company have received grants of
options to purchase shares of the Company's Common Stock pursuant to the 1994
Stock Option Plan. After the closing of this offering, directors of the Company

to the 1998 Stock Option Plan. See "-- Incentive Stock Plans" and "Certain
Transactions."

INCENTIVE STOCK PLANS
 
     1994 Stock Plan. The Company's 1994 Stock Plan, as amended and restated
(the "1994 Plan") provides for the granting to employees of incentive stock
options within the meaning of Section 422 of the Internal Revenue Code of 1986,
as amended (the "Internal Revenue Code"), and for the granting to employees and
consultants of nonstatutory stock options and stock purchase rights ("SPRs").
The 1994 Plan, as amended and restated, was approved by the Board of Directors
in April 1998 and is expected to be approved by the stockholders in May 1998.
Unless terminated sooner, the 1994 Plan will terminate automatically in July
2004. A total of 1,610,000 shares of Common Stock are currently reserved for
issuance pursuant to the 1994 Plan. The 1994 Plan may be administered by the
Board of Directors or a committee of the Board (the "Administrator"), which
Administrator shall, in the case of options intended to qualify as
"performance-based compensation" within the meaning of Section 162(m) of the
Code, consist of two or more "outside directors" within the meaning of Section
162(m) of the Code. The Administrator has the power to determine the terms of
the options or SPRs granted, including, but not limited to, the exercise price,
the number of shares subject to each option or SPR, the exercisability thereof,
and the form of consideration payable upon such exercise. In addition, the Board
has the authority to amend, suspend or terminate the 1994 Plan, provided that no
such action may affect any share of Common Stock previously issued and sold or
any option previously granted under the 1994 Plan. Options and SPRs granted
under the 1994 Plan are not generally transferable by the optionee, other then
by will or the laws of descent and distribution, and each option and SPR is
exercisable during the lifetime of the optionee only by such optionee. Options
granted under the 1994 Plan must generally be exercised within three months of
the end of optionee's status as an employee or consultant of the Company, or
within twelve months after such optionee's termination by death or disability,
but in no event later than the expiration of the option's ten year term. In the
case of SPRs, unless the Administrator determines otherwise, the restricted
stock purchase agreement shall grant the Company a repurchase option exercisable
upon the voluntary or involuntary termination of the purchaser's employment with
the Company for any reason (including death or disability). The purchase price
for shares repurchased pursuant to the restricted stock purchase agreement shall
be the original price paid by the purchaser and may be paid by cancellation of
any indebtedness of the purchaser to the Company. The repurchase option shall
lapse at a rate determined by the Administrator. The exercise price of all
incentive stock options granted under the 1994 Plan must be at least equal to
the fair market value of the Common Stock on the date of grant, unless adjusted
by the Administrator to the fair market value on the date of such adjustment if
the fair market value of the Company's Common Stock shall have declined since
the date the option was granted. The exercise price of nonstatutory stock
options and SPRs granted under the 1994 Plan is determined by the Administrator,
but with respect to nonstatutory stock options intended to qualify as
"performance-based compensation" within the meaning of
 
                                       46
<PAGE>   48
 
Section 162(m) of the Code, the exercise price must at least be equal to the
fair market value of the Common Stock on the date of grant, unless adjusted by
the Administrator to the fair market value on the date of such adjustment if the
fair market value of the Company's Common Stock shall have declined since the
date the option was granted. With respect to any participant who owns stock
possessing more than 10% of the voting power of all classes of the Company's
outstanding capital stock or any parent or subsidiary, the exercise price of any
incentive stock option granted must equal at least 110% of the fair market value
on the grant date and the term of such incentive stock option must not exceed
five years. The term of all other options granted under the 1994 Plan may not
exceed ten years. The 1994 Plan provides that in the event of a merger of the
Company with or into another corporation, a sale of substantially all of the
Company's assets or a like transaction involving the Company, options may be
granted with a per share exercise price of less than fair market value on the
date of the grant and each option shall be assumed or an equivalent option
substituted by the successor corporation. If the outstanding options are not
assumed or substituted as described in the preceding sentence, the Administrator
shall provide for the optionee to have the right to exercise the option or SPR
as to all of the optioned stock, including shares as to which it would not
otherwise be exercisable. If the administrator makes an option or SPR
exercisable in full in the event of a merger or sale of assets, the
administrator shall notify the optionee that the option or SPR shall be fully
exercisable for a period of fifteen days from the date of such notice, and the
option or SPR will terminate upon the expiration of such period.
 
     1998 Director Option Plan. Non-employee directors are entitled to
participate in the 1998 Director Option Plan (the "Director Plan"). The Director
Plan was adopted by the Board of Directors in April 1998 and is expected
approved by the stockholders in May 1998, but it will not become effective until
its approval which shall be required within 12 months of the Board's adoption of
the Director Plan. The Director Plan has a term of ten years, unless terminated
sooner by the Board. A total of 300,000 shares of Common Stock have been
reserved for issuance under the Director Plan. The Director Plan provides for
the automatic grant of 9,000 shares of Common Stock (the "First Option") to each
non-employee director on the effective date of this offering. After the First
Option is granted to the non-employee director, he or she shall automatically be
granted an option to purchase 9,000 shares (a "Subsequent Option") each year on
the date of the annual stockholder's meeting of the Company, if on such date he
or she shall have served on the Board for at least six months. Each First Option
and each Subsequent Option shall have a term of 10 years and the shares subject
to the option shall vest in equal monthly increments over the one year period
immediately following the date of grant. The exercise price of the First Option
shall be the initial price to public of the shares offered in this Offering. The
exercise price of each Subsequent Option shall be 100% of the fair market value
per share of the Common Stock, generally determined with reference to the
closing price of the Common Stock as reported on the Nasdaq National Market on
the date of grant. In the event of a merger of the Company or the sale of
substantially all of the assets of the Company, each option shall become fully
vested and exercisable for a period of thirty days from the date the Board
notifies the optionee of the option's full exercisability, after which period
the option shall terminate. Options granted under the Director Plan must be
exercised within three months of the end of the optionee's tenure as a director
of the Company, or within twelve months after such director's termination by
death or disability, but in no event later than the expiration of the option's
ten year term. No option granted under the Director Plan is transferable by the
optionee other than by will or the laws of descent and distribution, and each
option is exercisable, during the lifetime of the optionee, only by such
optionee.
 
     1998 Employee Stock Purchase Plan. The Company's 1998 Employee Stock
Purchase Plan (the "Purchase Plan") was approved by the Board of Directors in
April 1998 and is expected to be approved by the stockholders in May 1998. The
Company has reserved a total of 300,000 shares of Common Stock for issuance
thereunder. No shares have been issued under the Purchase Plan to date. The
Purchase Plan, which is intended to qualify under Section 423 of the Internal
Revenue Code of 1986, as amended (the "Code"), will be administered by the Board
of Directors of the Company or by a committee appointed by the Board of
Directors. Under the Purchase Plan, the Company will withhold a specified
percentage (not to exceed 15%) of each salary payment to participating employees
over certain offering periods. Any employee who is currently employed for at
least 30 hours per week will be eligible to participate in the Purchase Plan.
Unless the Board of Directors or its committee determines otherwise, each
offering period will run for 24 months and will be divided into four consecutive
purchase periods of approximately six months. The first offering period will
                                       47
<PAGE>   49
 
commence on the effective date of this Prospectus and will end on December 31,
1999. The first purchase period will commence on the effective date of this
Prospectus and will end on December 31, 1998. New 24 month offering periods will
commence every January 1 and July 1 thereafter. In the event of a change in
control of the Company, including a merger of the Company with or into another
corporation, or the sale of all or substantially all of the assets of the
Company, the offering and purchase periods then in progress will be shortened
unless the rights to purchase stock are assumed by the successor or acquiring
company. The price at which Common Stock will be purchased under the Purchase
Plan is equal to 85% of the fair market value of the Common Stock on the first
day of the applicable offering period or the last day of the applicable purchase
period, whichever is lower. Employees may end their participation in the
offering at any time during the offering period, and participation ends
automatically on termination of employment with the Company. The maximum number
of shares that a participant may purchase on the last day of any offering period
is determined by dividing the payroll deductions accumulated during the purchase
period by the purchase price. However, no person may purchase shares under the
Purchase Plan to the extent such person would own and/or hold outstanding
options to purchase 5% or more of the total combined value or voting power of
all classes of the capital stock of the Company or of any of its subsidiaries,
or to the extent that such person's rights to purchase stock under all employee
stock purchase plans would accrue at a rate that exceeds $25,000 worth of stock
for any calendar year. The Board of Directors may amend the Purchase Plan at any
time. The Purchase Plan will terminate in April 2008, unless terminated earlier
in accordance with the provisions of the Purchase Plan.
 
CHANGE OF CONTROL ARRANGEMENTS
 
     David H. Maupin and Michael J. Magliochetti, PhD. have been granted options
to purchase Common Stock pursuant to option agreements that provide for
acceleration of vesting of certain options so that such options shall
immediately become fully exercisable in the event of certain changes of control.
 
LIMITATIONS ON DIRECTORS' LIABILITY AND INDEMNIFICATION
 
     The Company's Certificate of Incorporation limits the liability of
directors to the maximum extent permitted by Delaware law. Delaware law provides
that directors of a corporation will not be personally liable for monetary
damages for breach of their fiduciary duties as directors, except liability for
(i) any breach of their duty of loyalty to the corporation or its stockholders,
(ii) acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) unlawful payments of dividends or unlawful
stock repurchases or redemptions, or (iv) any transaction from which the
director derived an improper personal benefit. Such limitation of liability does
not apply to liabilities arising under the federal securities laws and does not
affect the availability of equitable remedies such as injunctive relief or
rescission.
 
     The Company's Bylaws provide that the Company shall indemnify its directors
and executive officers and may indemnify its other officers and employees and
other agents to the fullest extent permitted by law. The Company believes that
indemnification under its Bylaws covers at least negligence and gross negligence
on the part of indemnified parties. The Company's Bylaws also permit it to
secure insurance on behalf of any officer, director, employee or other agent for
any liability arising out of his or her actions in such capacity, regardless of
whether the Bylaws would permit indemnification.
 
     The Company will, prior to the completion of this offering, enter into
agreements to indemnify its directors and executive officers, in addition to
indemnification provided for in the Company's Bylaws. These agreements, among
other things, indemnify the Company's directors and executive officers for
certain expenses (including attorneys' fees), judgments, fines and settlement
amounts incurred by any such person in any action or proceeding, including any
action by or in the right of the Company arising out of such person's services
as a director or executive officer of the Company, any subsidiary of the Company
or any other company or enterprise to which the person provides services at the
request of the Company. The Company believes that these provisions and
agreements are necessary to attract and retain qualified persons as directors
and executive officers.

     Pursuant to an Investor Rights Agreement, the holders of the Company's
Preferred Stock agreed to vote their shares of Preferred Stock to fix the number
of directors at five. Pursuant to this agreement, the board was to consist of
one director designated by the holders of the Company's Series A Preferred
Stock, to be designated by Medical Science Partners, L.P.; one director
designated by the holders of the Company's Series B Preferred Stock, to be
designated by Sprout Capital VII, L.P.; the duly elected, qualified and acting
President of the Company; and two directors designated jointly by the President
of the Company and all holders of the Company's Preferred Stock. Directors
Robert E. Curry, Ph.D. and David H. Maupin have served as members of the board
pursuant to this voting arrangement, which terminates upon completion of this
offering.
 
     The Company entered into an agreement in March 1994 with David H. Maupin
containing antidilution provisions which allowed Mr. Maupin to purchase
additional shares of Common Stock at fair market value based upon a certain
formula. In November 1995, the Company issued 42,500 shares of Common Stock at
$0.20 per share under the agreement.
 
     The Company expects to enter into a financing arrangement with certain of
its principal stockholders during April 1998. Under this arrangement, such
stockholders would provide the Company with a line of credit of up to $5.0
million in the event that the Company requires any additional funding prior to
receiving the net proceeds of this offering. In exchange for this line, the
Company has agreed to issue warrants to the stockholders to purchase an
aggregate of 50,000 shares of Common Stock at the initial public offering price
per share. The remaining terms of this credit facility are currently being
negotiated by the Company and such stockholders. To date, the Company has not
borrowed any amounts under this arrangement.
 
     The Company has from time to time granted options and other compensation to
its directors and executive officers.
 
     All future transactions, including any loans from the Company to its
officers, directors, principal stockholders or affiliates, will be approved by a
majority of the Board of Directors, including a majority of the independent and
disinterested members of the Board of Directors or, if required by law, a
majority of disinterested stockholders, and will be on terms no less favorable
to the Company than could be obtained from unaffiliated third parties.
 
     This offering is being made pursuant to Rule 2720 of the Conduct Rules of
the NASD because certain associates of DLJ own in excess of 10% of the Common
Stock of the Company prior to this offering. Rule 2720 provides that, among
other things, when an NASD member participates in the underwriting of equity
securities of a company in which there exists a conflict of interest, the price
at which such equity securities are to be distributed to the public can be no
higher than that recommended by a qualified independent underwriter ("QIU")
meeting certain standards. CIBC Oppenheimer Corp. will assume the
responsibilities of acting as the QIU in connection with this offering.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     Upon completion of this offering, the total number of shares of all classes
of stock which the Company has authority to issue will be 50,000,000 shares of
Common Stock, par value $0.01 per share and 5,000,000 shares of Preferred Stock,
par value $0.01 per share. As of March 31, 1998, 1,121,633 shares of Common
Stock were issued and outstanding and held by 12 stockholders and 5,834,404
shares of Preferred Stock were issued and outstanding and held by 46
stockholders. All outstanding shares of Preferred Stock will be converted into
shares of Common Stock upon completion of this offering.
 
COMMON STOCK
 
     Each holder of Common Stock is entitled to one vote for each share held on
all matters to be voted upon by the stockholders and there are no cumulative
voting rights. Subject to preferences that may be applicable to any outstanding
Preferred Stock, holders of Common Stock are entitled to receive ratably such
dividends as may be declared by the Board of Directors out of funds legally
available therefor. See "Dividend Policy." In the event of a liquidation or
dissolution of the Company, holders of Common Stock would be entitled to share
in the Company's assets remaining after the payment of liabilities and the
satisfaction of any liquidation preference granted the holders of any
outstanding shares of Preferred Stock. Holders of Common Stock have no
preemptive or conversion rights or other subscription rights. There are no
redemption or sinking fund provisions applicable to the Common Stock. All
outstanding shares of Common Stock are, and the shares of Common Stock offered
by the Company in this offering, when issued and paid for, will be, fully paid
and nonassessable. The rights, preferences and privileges of the holders of
Common Stock are subject to, and may be adversely affected by, the rights of the
holders of shares of any series of Preferred Stock which the Company may
designate in the future.
 
PREFERRED STOCK
 
     The Board of Directors is authorized, subject to any limitations prescribed
by law, without stockholder approval, from time to time to provide in the
issuance of one or more series of Preferred Stock, each of such series to have
such rights and preferences, including voting rights, dividend rights,
conversion rights, redemption privileges and liquidation preferences, as shall
be determined by the Board of Directors. Issuances of Preferred Stock, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of making it more difficult for
a third party to acquire, or of discouraging a third party from attempting to
acquire, a majority of the outstanding voting stock of the Company.
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
 
     The holders of approximately 5,834,404 shares of Common Stock (assuming the
conversion of all outstanding shares of Preferred Stock into Common Stock upon
completion of this offering) (the "Registrable Securities") or their transferees
are entitled to certain rights with respect to the registration of such shares
under the Securities Act. These rights are provided under the terms of an
agreement between the Company and the holders of Registrable Securities. The
holders of at least 35% of the Registrable Securities may require, on two
occasions, that the Company use its best efforts to register the Registrable
Securities for public resale, provided, among other limitations, that the
proposed aggregate selling price to the public is at least $2 million. If the
Company registers any of its Common Stock either for its own account or for the
account of other security holders, the holders of Registrable Securities are
entitled to include their shares of Common Stock in the registration, subject to
the ability of the underwriters to limit the number of shares included in the
offering. The holders of at least 15% of the Registrable Securities may also
require the Company, on four occasions, but not more than once during any
12-month period, to register all or a portion of their Registrable Securities on
Form S-3 when use of such form becomes available to the Company, provided, among
other limitations, that the proposed aggregate selling price (net of any
underwriters' discounts or commissions) is at least $250,000. The Company will
not be required to effect any registration, other than a registration on
                                       52
<PAGE>   54
 
Form S-3 or any successor form relating to secondary offerings within six months
after the effective date of any other Registration Statement of the Company. All
registration expenses must be borne by the Company and all selling expenses
relating to Registrable Securities must be borne by the holders of the
securities being registered. The holders of Registrable Securities have waived
their right to have shares of Common Stock registered under the Securities Act
as part of this offering and for a period of 180 days after the date of this
Prospectus.
 
CERTAIN CHARTER AND BYLAWS PROVISIONS AND DELAWARE ANTI-TAKEOVER STATUE
 
     Certain provisions of the Company's Restated Certificate of Incorporation
and Bylaws may have the effect of making it more difficult for a third party to
acquire, or of discouraging a third party from attempting to acquire, control of
the Company. Such provisions could limit the price that certain investors might
be willing to pay in the future for shares of the Company's Common Stock.
Certain of these provisions allow the Company to issue Preferred Stock without
any vote or further action by the stockholders, eliminate the right of
stockholders to act by written consent without a meeting and eliminate
cumulative voting in the election of directors. These provisions may make it
more difficult for stockholders to take certain corporate actions and could have
the effect of delaying or preventing a change in control of the Company. In
addition, the Company is subject to Section 203 of the Delaware General
Corporation Law which, subject to certain exceptions, prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder, unless: (i) prior to such date, the Board of Directors of the
corporation approved either the business combination or the transaction which
resulted in the stockholder becoming an interested stockholder; (ii) upon
consummation of the transaction which resulted in the stockholder becoming an
interested stockholder; the interested stockholder owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced, excluding for purposes of determining the number of shares
outstanding those shares owned by persons who are directors and also officers
and by employee stock plans in which employee participants do not have the right
to determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer; or (iii) on or subsequent to such date,
the business combination is approved by the Board of Directors and authorized at
an annual or special meeting of stockholders, and not by written consent, by the
affirmative vote of at least 66 2/3% of the outstanding voting stock which is
not owned by the interested stockholder.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Company's Common Stock is Norwest
Bank Minnesota, N.A. Its telephone number is (800) 468-9716.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to this offering, there has been no market for the Common Stock of
the Company. Future sales of substantial amounts of Common Stock in the public
market could adversely affect market prices prevailing from time to time. Sales
of substantial amounts of Common Stock of the Company in the public market after
the restrictions lapse, or the availability of such shares for sale, could
adversely affect the prevailing market price and the ability of the Company to
raise equity capital in the future.
 
     Upon the completion of this offering, the Company will have
shares of Common Stock outstanding, assuming no exercise of the Underwriters'
over-allotment option. Of these shares, the           shares sold in this
offering will be freely tradable without restriction under the Securities Act,
unless held by "affiliates" of the Company, as that term is defined in Rule 144
under the Securities Act. As a result of lock-up agreements between certain
stockholders and the Underwriters, the remaining 6,956,037 shares will not
become available for sale in the public market until 180 days after the date of
this Prospectus subject in some cases to the volume and other restrictions of
Rule 144 and Rule 701 of the Securities Act. Shares of Common Stock outstanding
upon completion of this offering and held by existing stockholders will be
"restricted securities" as that term is defined in Rule 144 under the Securities
Act ("Restricted Shares"). Restricted Shares may be sold in the public market
only if registered or if they qualify for an exemption from registration under
Rules 144, 144(k) or 701 promulgated under the 1933 Act, which rules are
summarized below. Sales of the Restricted Shares in the public market, or the
availability of such shares for sale, could adversely affect the market price of
the Common Stock.
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares for at least one
year is entitled to sell in "broker's transactions" or to market makers, within
any three-month period, a number of shares that does not exceed the greater of
(i) one percent of the number of shares of Common Stock then outstanding
(approximately        shares immediately after this offering) or (ii) the
average weekly trading volume of the Common Stock during the four calendar weeks
preceding the required filing of a Form 144 with respect to such sale. Sales
under Rule 144 are generally subject to certain manner of sale provisions and
notice requirements and to the availability of current public information about
the Company. Under Rule 144(k), a person who is not deemed to have been an
affiliate of the Company at any time during the 90 days preceding a sale, and
who has beneficially owned the shares proposed to be sold for at least two
years, is entitled to sell such shares without having to comply with the manner
of sale, public information, volume limitation or notice provisions of Rule 144.
Under Rule 701 under the Securities Act, persons who purchase shares upon
exercise of options granted prior to the effective date of this offering are
entitled to sell such shares 90 days after the closing of this offering in
reliance on Rule 144, without having to comply with the holding period
requirements of Rule 144 and, in the case of non-affiliates, without having to
comply with the public information, volume limitation or notice provisions of
Rule 144.
 
     Each of the Company, its executive officers and directors and certain
stockholders of the Company has agreed, subject to certain exceptions, not to
(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 transfer or dispose of, directly or indirectly,
any shares of Common Stock or any securities convertible into or exercisable for
Common Stock or (ii) enter into any swap or other arrangement that transfers all
or substantially all or a portion of the economic consequences associated with
the ownership of any Common Stock (regardless of whether any of the transactions
described in clause (i) or (ii) is to be settled by the delivery of the Common
Stock, or such other securities, in cash or otherwise) for a period of 180 days
after the date of this Prospectus without the prior written consent of DLJ. In
addition, during such period, the Company has also agreed not to file any
registration statement with respect to, and each of its stockholders has agreed
not to make any demand for, or exercise any right with respect to, the
registration of any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock without DLJ's prior written
consent.
 
     Approximately 90 days after the date of this Prospectus, the Company
intends to file a Registration Statement on Form S-8 covering shares issuable
under the Company's 1994 Stock Plan (including shares subject to then
outstanding options under such plans), 1998 Director Option Plan and 1998
Employee Stock Purchase Plan, thus permitting the resale of such shares in the
public market without restriction under the Securities Act after expiration of
the applicable lock-up agreements.

     The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase and accept delivery of the shares of Common Stock
offered hereby are subject to approval by their counsel of certain legal matters
and to certain other conditions. The Underwriters are obligated to purchase and
accept delivery of all the shares of Common Stock offered hereby (other than
those shares covered by the over-allotment option described below) if any are
purchased.
 
     The Underwriters initially propose to offer the shares of Common Stock in
part directly to the public at the initial public offering price set forth on
the cover page of this Prospectus and in part to certain dealers (including the
Underwriters) at such price less a concession not in excess of $     per share.
The Underwriters may allow, and such dealers may re-allow, to certain other
dealers a concession not in excess of $     per share. After the initial
offering of the Common Stock, the public offering price and other selling terms
may be changed by the Representative at any time without notice. The
Underwriters do not intend to confirm sales to any accounts over which they
exercise discretionary authority.
 
     The Company has granted to the Underwriters an option, exercisable within
30 days after the date of this Prospectus, to purchase, from time to time, in
whole or in part, up to an aggregate of        additional shares of Common Stock
at the initial public offering price less underwriting discounts and
commissions. The Underwriters may exercise such option solely to cover
over-allotments, if any, made in connection with the offering. To the extent
that the Underwriters exercise such option, each Underwriter will become
obligated, subject to certain conditions, to purchase its pro rata portion of
such additional shares based on such Underwriter's percentage underwriting
commitment as indicated in the preceding table.
 
     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.
 
     Each of the Company, its executive officers and directors and certain of
the stockholders of the Company has agreed, subject to certain exceptions, not
to (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 transfer or dispose of, directly or indirectly,
any shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock or (ii) enter into any swap or other arrangement
that transfers all or a portion of the economic consequences associated with the
ownership of any Common Stock (regardless of whether any of the transactions
described in clause (i) or (ii) is to be settled by the delivery of Common
Stock, or such other securities, in cash or otherwise) for a period of 180 days
after the date of this Prospectus without the prior written consent of DLJ. In
addition, during such period, the Company has also agreed not to file any
registration statement with respect to, and each of its stockholders has
 
                                       55
<PAGE>   57
 
agreed not to make any demand for, or exercise any right with respect to, the
registration of any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock without DLJ's prior written
consent. The Company and each of its executive officers, directors and certain
stockholders of the Company have also waived any right of first refusal that
they may have with respect to the Common Stock issued pursuant to this offering.
 
     Prior to this offering, there has been no established trading market for
the Common Stock. The initial public offering price for the shares of Common
Stock offered hereby will be determined by negotiation among the Company and the
Representatives. The factors to be considered in determining the initial public
offering include the history of and the prospects for the industry in which the
Company competes, the past and present operations of the Company, the historical
results of operation of the Company, the prospects for future earnings of the
Company, the recent market prices of securities of generally comparable
companies and the general condition of the securities markets at the time of the
offering.
 
     Other than in the U.S., no action has been taken by the Company or the
Underwriters that would permit a public offering of the shares of Common Stock
offered hereby in any jurisdiction where action for that purpose is required.
The shares of Common Stock offered hereby may not be offered or sold, directly
or indirectly, nor may this Prospectus or any other offering material or
advertisement in connection with the offer and sale of any such shares of Common
Stock be distributed or published in any jurisdiction, except under
circumstances that will result in compliance with the applicable rules and
regulations of such jurisdiction. Persons into whose possession this Prospectus
comes are advised to inform themselves about and to observe any restrictions
relating to the offering of the Common Stock and the distribution of this
Prospectus. This Prospectus does not constitute an offer to sell or a
solicitation of an offer to buy any shares of Common Stock offered hereby in any
jurisdiction in which such an offer or a solicitation in unlawful.
 
     In connection with this offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Common Stock. Specifically, the Underwriters may overallot the offering,
creating a syndicate short position. The Underwriters may bid for and purchase
shares of Common Stock in the open market to cover such syndicate short position
or to stabilize the price of the Common Stock. In addition, the underwriting
syndicate may reclaim selling concessions from syndicate members and selected
dealers if they repurchase previously distributed Common Stock in syndicate
covering transactions, in stabilizing transactions or otherwise. These
activities may stabilize or maintain the market price of the Common Stock above
independent market levels. The Underwriters are not required to engage in these
activities, and may end any of these activities at any time.
 
     This offering is being made pursuant to Rule 2720 of the Conduct Rules of
the NASD because certain associates of DLJ own in excess of 10% of the Common
Stock of the Company prior to this offering. Rule 2720 provides that, among
other things, when an NASD member participated in the underwriting of equity
securities of a company in which there exists a conflict of interest, the price
at which such equity securities are to be distributed to the public can be no
higher than that recommended by a qualified independent underwriter meeting
certain standards. CIBC Oppenheimer Corp. will assume responsibilities of acting
as the QIU in connection with this offering.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors
UroSurge, Inc.
Coralville, Iowa
 
     We have audited the accompanying balance sheets of UroSurge, Inc., a
development stage company, as of December 31, 1996 and 1997, and the related
statements of operations, stockholders' equity, and cash flows for the years
ended December 31, 1995, 1996 and 1997 and the period from August 6, 1993, date
of incorporation, to December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Urosurge, Inc., as of
December 31, 1996 and 1997, and the results of its operations and its cash flows
for the years ended December 31, 1995, 1996 and 1997 and the period from August
6, 1993, date of incorporation, to December 31, 1997 in conformity with
generally accepted accounting principles.

                         (A DEVELOPMENT STAGE COMPANY)
                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1.  NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
     Nature of business:  The Company has acquired various licenses that allow
it to develop, manufacture and market devices for the diagnosis, treatment and
management of urinary incontinence and other genito-urinary conditions.
 
     Risk and uncertainties:  The Company is in the development stage. It needs
to obtain regulatory approval from the Food and Drug Administration ("FDA")
prior to selling many of its products within the United States, and foreign
regulatory approval must be obtained to sell many of its products
internationally. There can be no assurance that the Company's products will
receive regulatory approvals and a substantial amount of time may pass before
significant revenue is realized. In addition, the primary component of one of
the Company's products is purchased from a single supplier under an agreement
that expires in 2000, subject to an automatic two-year extension.
 
     Accounting estimates:  The preparation of the financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenue and expenses during
the reporting period. Actual results could differ from those estimates.
 
     A summary of the Company's significant accounting policies follows:
 
     Cash and cash equivalents:  For purposes of reporting cash flows, the
Company considers all cash accounts which are not subject to withdrawal
restrictions or penalties, and all highly liquid debt instruments with a
maturity of three months or less, to be cash equivalents.
 
     Short-term investments:  Short-term investments include certificates of
deposit of $2,000,000 and held to maturity U.S. Government securities of
$1,129,396 which the Company has the positive intent and ability to hold to
maturity and are stated at amortized cost. The fair value of U.S. Government
securities, which matured in early 1998, approximates their carrying value.
 
     Inventories:  Inventories are stated at the lower of cost (first-in,
first-out method) or market. The inventories consist primarily of purchased
materials available for sale and to be used in research and development
activities.
 
     Leasehold improvements and equipment:  Leasehold improvements and equipment
are stated at cost. Depreciation of furniture and equipment is computed
primarily by accelerated methods over estimated useful lives of five to seven
years. Leasehold improvements are amortized by the straight-line method over the
terms of the leases, plus optional renewals.
 
     Licenses:  License acquisition costs are amortized by the straight-line
method over their estimated economic life which varies between five and fifteen
years. These licenses are periodically reviewed for impairment based upon an
assessment of future operations to ensure that they are appropriately valued.
 
     Revenue recognition:  Sales of medical devices are recognized as the
products are shipped.
 
     Research and development:  Research and development costs are charged to
expense as incurred.
 
     Deferred income taxes:  Deferred income taxes are provided under the
liability method whereby deferred tax assets are recognized for deductible
temporary differences and net operating loss and tax credit carryforwards and
deferred tax liabilities are recognized for taxable temporary differences.
Temporary differences are the differences between the reported amounts of assets
and liabilities and their tax bases. Deferred tax assets are reduced by a
valuation allowance when, in the opinion of management, it is more likely

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
than not that some or all of the deferred tax assets will not be realized.
Deferred tax assets and liabilities are adjusted for the effects of changes in
tax laws and rates on the date of enactment.
 
     Stock options issued to employees and directors:  Compensation expense for
stock issued through a stock option plan is accounted for using the intrinsic
value based method of accounting prescribed by APB Opinion 25, Accounting for
Stock Issued to Employees. Under this method, compensation is measured as the
difference, if any, between the fair value of the stock at the date of award
less the amount required to be paid for the stock. The difference, if any, is
charged to expense over the periods of service.
 
     The estimated fair value used for the stock options granted was determined
on a periodic basis by the Company's Board of Directors.
 
     Stock options issued to nonemployees:  The Company uses the Black-Scholes
model to determine the fair value of stock options issued to nonemployees. The
fair value of options granted is amortized and expensed over the period of
service.
 
     Loss per share:  The FASB has issued SFAS No. 128, "Earnings Per Share,"
which supersedes APB Opinion No. 15. SFAS No. 128 requires the presentation of
basic and diluted earnings (loss) per share by all entities that have common
stock or potential common stock, such as options, warrants and convertible
securities outstanding. Basic per share amounts are computed by dividing net
income (loss) (the numerator) by the weighted-average number of common shares
outstanding (the denominator). Diluted per share amounts assume the conversion,
exercise or issuance of all potential common stock unless the effect is to
reduce the loss or increase the income per common share from continuing
operations. The dilutive effect of stock options is reflected by application of
the treasury stock method and the dilutive effect of convertible preferred stock
is reflected by application of the if-converted method. For each of the periods
basic and diluted loss per share were the same since there was no dilutive
effect from stock options or convertible preferred stock. There are no issuances
of stock options that are considered "nominal issuances" under the Securities
and Exchange Commission's Staff Accounting Bulletin No. 98.
 
     Pro forma basic and diluted loss per share for the year ended December 31,
1997 is computed using the weighted average number of outstanding shares of
common stock determined above and the assumed conversion of Series A, B and C
convertible preferred stock into common stock (as of their date of original
issuance), which will occur upon the completion of the initial public offering,
as contemplated herein.
 
     Fair value of financial instruments:  The fair value of all the financial
instruments approximates their carrying value since all are liquid or have short
maturities.
 
     Recent accounting pronouncements:  In June 1997, the FASB issued SFAS No.
130, "Reporting Comprehensive Income." SFAS No. 130 establishes standards for
the reporting and display of comprehensive income and its components in a full
set of general purpose financial statements. Comprehensive income is defined as
the change in equity of a business enterprise during a period, resulting from
transactions and other events and circumstances from nonowner sources. The
impact of adopting SFAS No. 130, which is effective for the Company in 1998, has
not been determined.
 
     In June 1997, the FASB issued SFAS No. 131, "Disclosure About Segments of
an Enterprise and Related Information." SFAS No. 131 requires publicly-held
companies to report financial and other information about key revenue-producing
segments of the entity for which such information is available and is utilized
by the chief operating decision maker. Specific information to be reported for
individual segments includes profit or loss, certain revenue and expense items
and total assets. A reconciliation of segment financial information to amounts
reported in the financial statements would be provided. SFAS No. 131 is
effective for the Company in 1998. The Company operates in one business segment.

manufacture and market a number of products. The licenses require the payment of
royalties which vary up to 6% of the revenues related to the products.
 
     One license requires additional fees totaling $75,000 contingently payable
if the Company is able to meet specified regulatory milestones and receives FDA
clearance for the licensed product. This license also requires additional
license fees of $900,000 over five years upon receiving FDA approval.
 
     Royalty expense totaled $0, $637, $1,067 and $1,704 for the years ended
December 31, 1995, 1996 and 1997 and the period from August 6, 1993, date of
incorporation, to December 31, 1997.
 
NOTE 3.  PLEDGED ASSETS AND RELATED DEBT
 
     The Company has various notes payable, collateralized by equipment and
leasehold improvements, totaling $174,690 as of December 31, 1997. These notes

NOTE 4.  STOCKHOLDERS' EQUITY
 
     The Company has issued three series of convertible preferred stock under
investment agreements as follows: 1,685,000 shares of Series A convertible
preferred stock, ($.01 par value) ("Series A") for $1.00 per share under an
Investment Agreement dated March 11, 1994, 2,675,000 shares of Series B
convertible preferred stock, ($.01 par value) ("Series B") for $2.00 per share
under an Investment Agreement dated September 29, 1995 and 1,474,404 shares of
Series C convertible preferred stock, ( $.01 par value) ("Series C") for $5.00
per share under an Investment Agreement dated June 13, 1997.
 
     Dividends:  In each fiscal year of the Company, the holders of Series A,
Series B and Series C (collectively, the "Preferred") shall be entitled to
receive, when and if declared by the Board of Directors, dividends in preference
to the holders of Common Stock ("Common") in an amount per share at least equal
to the product of (i) the per share amount, if any, of the cash dividend
declared, paid or set aside for the Common during such fiscal year, multiplied
by (ii) the number of whole shares of Common into which each such share of
Preferred is then convertible. Dividends on the Preferred shall not be
cumulative.
 
     Liquidation preference:  In the event of any liquidation, dissolution or
winding up of the Company, the holders of Series A, Series B and Series C shall
be entitled to receive in preference to the holders of Common amounts equal to
$1.00, $2.00 and $5.00 per share, respectively, plus declared and unpaid
dividends. Thereafter the holders of Common shall receive the remaining assets
of the Company. A consolidation or merger or sale of all or substantially all of
the assets of the Company shall be deemed to be a liquidation, dissolution or
winding up for purposes of the liquidation preference.
 
     Voting rights:  Pursuant to an Investor Rights Agreement, the holders of
the Company's Preferred Stock agreed to vote their shares of Preferred Stock to
fix the number of directors at five. Pursuant to this agreement, the board was
to consist of one director designated by the holders of the Company's Series A
Preferred Stock, to be designated by Medical Science Partners, L.P.; one
director designated by the holders of the Company's Series B Preferred Stock, to
be designated by Sprout Capital VII, L.P.; the duly elected, qualified and
acting President of the Company and two directors designated jointly by the
President of the Company; and all holders of the Company's Preferred Stock.
Directors Robert E. Curry, Ph.D. and David H. Maupin have served as members of
the board pursuant to this voting arrangement, which terminates upon completion
of the initial public offering.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Protective provisions:  So long as there shall be issued and outstanding at
least 67% of the total number of shares of Preferred ever issued, the Company
shall not, without first obtaining the affirmative vote of not less then 67% of
the then outstanding shares of Preferred (i) merge or consolidate into or with
any other corporation or sell all or substantially all of the Company's assets;
(ii) voluntarily or involuntarily liquidate, dissolve or wind up the Company or
its business; (iii) amend, repeal or add any provision to the Company's
Certificate of Incorporation if such action would alter or change any of the
preferences, rights, privileges or powers of, or the restrictions provided for
the benefit of, the Preferred, or increase or decrease the total number of
authorized shares of Preferred; (iv) authorize or issue any new or existing
class or series of capital stock (or any securities convertible into or
exercisable for any shares of capital stock) having any preference or priority
as to amounts distributable upon liquidation superior to or on parity with the
Preferred; (v) reclassify any Common into shares having any preference or
priority as to amounts distributable upon liquidation superior to or on parity
with the Preferred; or (vi) pay or declare any dividend or distribution on any
shares of its capital stock, or redeem, retire, repurchase or acquire any shares
of its capital stock (except for shares repurchased in accordance with
restricted stock purchase agreements with employees, consultants or directors
previously approved by the Board of Directors.)
 
     Conversion:  Each share of Preferred may be converted at the holder's
option at any time into one share of Common, subject to adjustment as provided
below.
 
     Automatic conversion:  The Preferred will be automatically converted into
Common at its then applicable conversion rate upon the earlier of (i) the
closing of an underwritten public offering of more than $15,000,000 of Company
stock for not less than $7.50 per share (a "Qualified Public Offering"), or (ii)
the date on which there are issued and outstanding a number of shares of
Preferred equal to less than 33% of the total number of shares of Preferred ever
issued by the Company.
 
     Conversion price adjustments:  The conversion price of the Series A, Series
B and Series C shall be subject to adjustment (i) proportionately for stock
splits, stock dividends, recapitalization, reclassifications, reorganizations,
etc. and (ii) on a broad-based weighted-average basis if the Company issues
additional shares of Common or Common equivalents (other than a total of
1,010,000 shares of Common under board approved stock option/stock purchase
plans and certain other customary exclusions) at a purchase price less than the
applicable conversion price. The conversion prices of the Series A, Series B and
Series C shall initially be $1.00, $2.00 and $5.00, respectively. The holders of
67% of each of the outstanding Series A, Series B and Series C may elect to
waive any price-based antidilution adjustment to the conversion price of their
stock.
 
     Right of first refusal:  In the event that the Company issues equity
securities or securities convertible or exercisable for equity securities (other
than up to 1,010,000 shares of Common issued pursuant to board approved stock
option/stock purchase plans and certain other customary exclusions), each of the
holders of Preferred shall be given the right to purchase a percentage of such
securities, on the same basis as the other investors, equal to the percentage
ownership of the Company (on a fully diluted basis) it holds prior to such
issuance, with an additional right of overallotment. A holder of Preferred may
apportion such holder's rights among itself and such general partners, officers
and other affiliates in such proportions as it deems appropriate. These rights
shall terminate upon the closing of the Company's first Qualified Public
Offering.
 
NOTE 5.  EMPLOYEE BENEFIT PLANS
 
     The Company has a defined contribution 401(k) plan covering all employees
fulfilling minimum age and service requirements. Employee contributions to the
plan are optional. The plan does not provide for a contribution by the employer.
 
     The Company has a Stock Option Plan for certain officers, directors,
employees and consultants whereby 1,010,000 shares of Common have been reserved
for issuance. Options for 763,500 shares of Common have

and consultants at prices equal to the estimated fair value of the stock at the
date of the grant and are exercisable and vest in a range from immediately to
over a four-year period. The options expire five years from the date of the
grants.
 
     For certain options granted, the Company recognizes as compensation expense
the excess of the deemed value for accounting purposes of the Common stock
issuable upon exercise of such options over the aggregate exercise price of such
options. In connection with these grants, $860,485 of deferred compensation has
been recorded. This compensation expense is being amortized over the vesting
period of each option. Compensation expense under the Plan totaled $122,041 for
the year ended December 31, 1997.
 
     A summary of the status of the Company's Stock Option Plan is as follows:

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Upon merger or sale of the Company, an additional 171,460 shares would
become fully exercisable. As of December 31, 1997, options to purchase 246,500
shares of Common were available for future grants.
 
     The Company has adopted the disclosure only provisions of Statement of
Financial Accounting Standards No. 123, "Accounting for Stock Based
Compensation." Had the Company elected to measure compensation based on the
grant date fair value of awards granted (the method described in FASB Statement
No. 123), reported net loss and loss per share would have been changed to the
pro forma amounts indicated below:

     The pro forma amounts shown above are estimated using the following
assumptions for grants in 1995, 1996 and 1997: no dividends, no price
volatility, risk-free interest rate of 5.84%, 6.27% and 5.71% and expected life
of options of four years.
 
     Subsequent to December 31, 1998, the Company reserved an additional 600,000
shares for future issuance under the plan discussed above, adopted a 1998
director stock option plan and a 1998 employee stock purchase plan. (see Note 9)
 
NOTE 6.  LEASE COMMITMENTS
 
     The Company leases its office building under a lease agreement that expires
June 30, 2000 with one five-year option to renew, whereby it pays monthly
rentals of $7,003 plus property taxes, special assessments, insurance and
maintenance costs. The Company signed a lease in December 1997 for an adjoining
building to be used for manufacturing. This lease commences on January 1, 1998
and requires monthly rentals of $8,050 plus property taxes, special assessments,
insurance and maintenance costs. The lease term is 29 months with one five year
option to renew. The Company plans to exercise both renewal options.

</TABLE>
 
     A valuation allowance totaling $4,236,100 as of December 31, 1997 was
established since it is uncertain if the Company will receive future income tax
benefit from loss carryovers. The amount of the carryforward is approximately
$9,591,000 of which $630,000 expires in 2009, $1,178,000 expires in 2010,
$2,690,000 expires in 2011 and $5,093,000 expires in 2012.
 
     The above loss carryforwards are subject to certain annual limitations
resulting from issuances of equity securities and may be further limited by
additional issuances. Such events could limit the eventual tax utilization of
these carryforwards.
 
NOTE 8.  COMMITMENTS AND CONTINGENCIES

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company is completing improvements to a leased building to be used as a
manufacturing facility. Leasehold improvements and other capital equipment
purchases with an estimated cost of $500,000 are anticipated through the second
quarter of 1998.
 
NOTE 9.  SUBSEQUENT EVENTS
 
     In April 1998 the Board of Directors authorized management of the Company
to file a registration statement with the Securities and Exchange Commission
permitting the Company to issue its common stock in an initial public offering.
The Company plans to use the proceeds to fund ongoing and future clinical
trials, research and development, marketing and sales activities, expansion of
manufacturing capabilities and for working capital and general corporate
purposes.
 
     In April 1998 the Company's Board of Directors approved a Restated
Certificate of Incorporation which eliminates the previous class of preferred
stock, authorizes a class of undesignated preferred stock and changes the number
of common shares authorized to 50,000,000 shares. The Restated Articles are to
be filed following the effectiveness of the initial public offering.
 
     In April 1998 the Company's Board of Directors approved a 1998 Director
Option Plan and has reserved 300,000 shares of common stock for issuance under
the plan. Nonemployee directors will annually be granted a nonstatutory option
to purchase 9,000 shares of common stock at the fair value on the date of the
grant, with the option vesting over four years.
 
     In April 1998 the Company's Board of Directors approved a 1998 Employee
Stock Purchase Plan and has reserved 300,000 shares for issuance under the plan.
The Company will withhold up to 15% of salary for participating employees, who
may acquire common stock at 85% of fair value of the common stock on the dates
specified in the plan.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law allows for the
indemnification of officers, directors and any corporate agents in the terms
sufficiently broad to indemnify such persons under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the
Securities Act of 1933, as amended (the "Act"). The Registrant's Restated
Certificate of Incorporation (Exhibit 3.1 hereto) and the Registrant's Bylaws
(Exhibit 3.3 hereto) provides for indemnification of the Registrant's directors,
officers, employees and other agents to the extent and under the circumstances
permitted by the Delaware General Corporation Law. The Registrant also intends
to enter into agreements with its directors and executive officers that will
require the Registrant among other things to indemnify them against certain
liabilities that may arise by reason of their status or service as directors to
the fullest extent not prohibited by Delaware law.
 
     The Underwriting Agreement (Exhibit 1.1 hereto) provides for
indemnification by the Underwriters of the Registrant, its directors and
officers, and by the Registrant of the Underwriters, for certain liabilities,
including liabilities arising under the Act, and affords certain rights of
contribution with respect thereto.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     Since March 31, 1995, the Registrant has issued and sold the following
unregistered securities:
 
          (a) Since March 31, 1995, the Registrant has granted stock options to
     employees, consultants and directors under its stock option plans covering
     an aggregate of 782,500 shares of the Registrant's Common Stock, at
     exercise prices ranging from $0.10 to $2.00 per share. Since March 31,
     1995, the Registrant has issued 794,500 shares of Common Stock to
     employees, consultants and directors upon exercise of stock options.
 
          (b) In September and October 1995, Registrant sold 2,675,000 shares of
     Series B Preferred Stock to 18 private investors at a purchase price of
     $2.00 per share.
 
          (c) In June 1997, Registrant sold 1,474,404 shares of Series C
     Preferred Stock to 36 private investors at a purchase price of $5.00 per
     share.
 
     The sales of the above securities were deemed to be exempt from
registration under the Securities Act in reliance on Section 4(2) of the
Securities Act, or Regulation D promulgated thereunder, or Rule 701 promulgated
under Section 3(b) of the Securities Act, as transactions by an issuer not
involving a public
                                      II-1
<PAGE>   75
 
offering or transactions pursuant to compensatory benefit plans and contracts
relating to compensation as provided under such Rule 701. The recipients of
securities in each such transaction represented their intention to acquire the
securities for investment only and not with a view to or for sale in connection
with any distribution thereof and appropriate legends were affixed to the share
certificates and instruments issued in such transactions. All recipients had
adequate access, through their relationships with the Registrant, to information
about the Registrant.

ITEM 17. UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
     The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing as specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

DONALDSON, LUFKIN & JENRETTE
  SECURITIES CORPORATION
CIBC OPPENHEIMER CORP.
  As representatives of the
   several Underwriters
   named in Schedule I hereto
   c/o Donaldson, Lufkin & Jenrette
    Securities Corporation
    277 Park Avenue
    New York, New York 10172

Dear Sirs:

               UroSurge, Inc., a Delaware corporation (the "Company"), proposes
to issue and sell _________shares of its Common Stock, $.01 par value per share
(the "Firm Shares") to the several underwriters named in Schedule I hereto (the
"Underwriters"). The Company also proposes to issue and sell to the several
Underwriters not more than an additional__________ shares of its Common Stock,
$.01 par value per share (the "Additional Shares") if requested by the
Underwriters as provided in Section 2 hereof. The Firm Shares and the Additional
Shares are hereinafter referred to collectively as the "Shares". The shares of
common stock of the Company to be outstanding after giving effect to the sales
contemplated hereby are hereinafter referred to as the "Common Stock".

               Section 1. Registration Statement and Prospectus. The Company has
prepared and filed with the Securities and Exchange Commission (the
"Commission") in accordance with the provisions of the Securities Act of 1933,
as amended, and the rules and regulations of the Commission thereunder
(collectively, the "Act"), a registration statement on Form S-1, including a
prospectus, relating to the Shares. The registration statement, as amended at
the time it became effective, including the information (if any) deemed to be
part of the registration statement at the time of effectiveness pursuant to


                                        -1-
<PAGE>   2

Rule 430A under the Act, is hereinafter referred to as the "Registration
Statement"; and the prospectus in the form first used to confirm sales of Shares
is hereinafter referred to as the "Prospectus". If the Company has filed or is
required pursuant to the terms hereof to file a registration statement pursuant
to Rule 462(b) under the Act registering additional shares of Common Stock (a
"Rule 462(b) Registration Statement"), then, unless otherwise specified, any
reference herein to the term "Registration Statement" shall be deemed to include
such Rule 462(b) Registration Statement.

               Section 2. Agreements to Sell and Purchase and Lock-Up
Agreements. On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company agrees to issue
and sell, and each Underwriter agrees, severally and not jointly, to purchase
from the Company at a price per Share of $______ (the "Purchase Price") the
number of Firm Shares set forth opposite the name of such Underwriter in
Schedule I hereto.

               On the basis of the representations and warranties contained in
this Agreement, and subject to its terms and conditions, the Company agrees to
issue and sell the Additional Shares and the Underwriters shall have the right
to purchase, severally and not jointly, up to_______. Additional Shares from the
Company at the Purchase Price. Additional Shares may be purchased solely for the
purpose of covering over-allotments made in connection with the offering of the
Firm Shares. The Underwriters may exercise their right to purchase Additional
Shares in whole or in part from time to time by giving written notice thereof to
the Company within 30 days after the date of this Agreement. You shall give any
such notice on behalf of the Underwriters and such notice shall specify the
aggregate number of Additional Shares to be purchased pursuant to such exercise
and the date for payment and delivery thereof, which date shall be a business
day (I) no earlier than two business days after such notice has been given (and,
in any event, no earlier than the Closing Date (as hereinafter defined)) and
(ii) no later than ten business days after such notice has been given. If any
Additional Shares are to be purchased, each Underwriter, severally and not
jointly, agrees to purchase from the Company the number of Additional Shares
(subject to such adjustments to eliminate fractional shares as you may
determine) which bears the same proportion to the total number of Additional
Shares to be purchased from the Company as the number of Firm Shares set forth
opposite the name of such Underwriter in Schedule I bears to the total number of
Firm Shares.

               The Company hereby agrees not to (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 transfer or dispose of, directly or indirectly, any shares of Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock or (ii) enter into any swap or other arrangement that transfers all
or a portion of the economic consequences associated with the ownership of


                                        -2-

any Common Stock (regardless of whether any of the transactions described in
clause (I) or (ii) is to be settled by the delivery of Common Stock, or such
other securities, in cash or otherwise), except to the Underwriters pursuant to
this Agreement, for a period of 180 days after the date of the Prospectus
without the prior written consent of Donaldson, Lufkin & Jenrette Securities
Corporation. Notwithstanding the foregoing, during such period (I) the Company
may grant stock options pursuant to the Company's existing stock option plan and
(ii) the Company may issue shares of Common Stock upon the exercise of an option
or warrant or the conversion of a security outstanding on the date hereof. The
Company also agrees not to file any registration statement with respect to any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock for a period of 180 days after the date of the
Prospectus without the prior written consent of Donaldson, Lufkin & Jenrette
Securities Corporation. Notwithstanding the foregoing, the Company may during
such period file a registration statement on Form S-8 relating to its employee
benefit plans; provided, however, that in no event shall such registration
statement on Form S-8 be used for resale of shares issued upon exercise of stock
options or stock purchase rights during such 180 day period and, provided
further that the Company shall not, during such 180 day period, waive any
provision of any stock option or stock purchase agreement that obligates the
optionee or purchaser, as the case may be, to enter into a 180 day lockup
agreement following the offering of the Company's Common Stock contemplated
hereby without the prior written consent of Donaldson Lufkin & Jenrette
Securities Corporation. The Company shall, prior to or concurrently with the
execution of this Agreement, deliver an agreement executed by the stockholders
of the Company listed on Schedule II hereto to the effect that such person will
not, during the period commencing on the date such person signs such agreement
and ending 180 days after the date of the Prospectus, without the prior written
consent of Donaldson, Lufkin & Jenrette Corporation, (A) engage in any of the
transactions described in the first sentence of this paragraph or (B) make any
demand for, or exercise any right with respect to, the registration of any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock. Such individuals shall also waive any right of
first refusal they may have with respect to the shares of Common Stock issuable
pursuant to the public offering contemplated hereby. The Company will not, in
the case of stockholders of the Company that are not listed on Schedule II
hereto, waive any provision of any stock option, stock purchase, registration
rights or similar agreement to which such stockholder and the Company are
parties which provides that stockholder(s) will enter into a 180 day lockup
agreement following the offering of the Company's Common Stock contemplated
hereby without the prior written consent of Donaldson Lufkin & Jenrette
Securities Corporation.

               The Company hereby confirms its engagement of CIBC Oppenheimer
("Oppenheimer") as, and Oppenheimer hereby confirms its agreement with the
Company to render services as, a "qualified independent underwriter", within the
meaning of Section (b)(15) of Rule 2720 of the National Association of

which the Shares will be sold to the public will not be higher than the maximum
price recommended by the QIU.

respective portions of the Shares as soon after the execution and delivery of

               Section 5. Agreements of the Company. The Company agrees with
you:

               (a) To advise you promptly and, if requested by you, to confirm
such advice in writing, (I) of any request by the Commission for amendments to
the Registration Statement or amendments or supplements to the Prospectus or for
additional information, (ii) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or of the suspension
of qualification of the Shares for offering or sale in any jurisdiction, or the
initiation of any proceeding for such purposes, (iii) when any amendment to the
Registration Statement becomes effective, (iv) if the Company is required to
file a Rule 462(b) Registration Statement after the effectiveness of this
Agreement, when the Rule 462(b) Registration Statement has become effective and
(v) of the happening of any event during the period referred to in Section 5(d)
below which makes any statement of a material fact made in the Registration
Statement or the Prospectus untrue or which requires any additions to or changes
in the Registration Statement or the Prospectus in order to make the statements
therein not misleading. If at any time the Commission shall issue any stop order
suspending the effectiveness of the Registration Statement, the Company will use
its best efforts to obtain the withdrawal or lifting of such order at the
earliest possible time.

               (b) To furnish to you one signed copy of the Registration
Statement as first filed with the Commission and of each amendment to it,
including all exhibits, and to furnish to you and each Underwriter designated by
you such number of conformed copies of the Registration Statement as so filed
and of each amendment to it, without exhibits, as you may reasonably request.

               (c) To prepare the Prospectus, the form and substance of which
shall be satisfactory to you, and to file the Prospectus in such form with the
Commission within the applicable period specified in Rule 424(b) under the Act;
during the period specified in Section 5(d) below, not to file any further
amendment to the Registration Statement and not to make any amendment or
supplement to the Prospectus of which you shall not previously have been advised
or to which you shall reasonably object after being so advised; and, during such
period, to prepare and file with the Commission, promptly upon your reasonable
request, any amendment to the Registration Statement or amendment or supplement
to the Prospectus which may be necessary or advisable in connection with the
distribution of the Shares by you, and to use its best efforts to cause any such
amendment to the Registration Statement to become promptly effective.

               (d) Prior to 10:00 A.M., New York City time, on the first
business day after the date of this Agreement and from time to time thereafter
for such period as in the opinion of counsel for the Underwriters a prospectus
is required by law to be delivered in connection with sales by an Underwriter or
a dealer, to furnish in New York City to each


                                       -5-

<PAGE>   6

Underwriter and any dealer as many copies of the Prospectus (and of any
amendment or supplement to the Prospectus) as such Underwriter or dealer may
reasonably request.

               (e) If during the period specified in Section 5(d), any event
shall occur or condition shall exist as a result of which, in the opinion of
counsel for the Underwriters, it becomes necessary to amend or supplement the
Prospectus in order to make the statements therein, in the light of the
circumstances when the Prospectus is delivered to a purchaser, not misleading,
or if, in the opinion of counsel for the Underwriters, it is necessary to amend
or supplement the Prospectus to comply with applicable law, forthwith to prepare
and file with the Commission an appropriate amendment or supplement to the
Prospectus so that the statements in the Prospectus, as so amended or
supplemented, will not in the light of the circumstances when it is so
delivered, be misleading, or so that the Prospectus will comply with applicable
law, and to furnish to each Underwriter and to any dealer as many copies thereof
as such Underwriter or dealer may reasonably request.

               (f) Prior to any public offering of the Shares, to cooperate with
you and counsel for the Underwriters in connection with the registration or
qualification of the Shares for offer and sale by the several Underwriters and
by dealers under the state securities or Blue Sky laws of such jurisdictions as
you may request, to continue such registration or qualification in effect so
long as required for distribution of the Shares and to file such consents to
service of process or other documents as may be necessary in order to effect
such registration or qualification; provided, however, that the Company shall
not be required in connection therewith to qualify as a foreign corporation in
any jurisdiction in which it is not now so qualified or to take any action that
would subject it to general consent to service of process or taxation other than
as to matters and transactions relating to the Prospectus, the Registration
Statement, any preliminary prospectus or the offering or sale of the Shares, in
any jurisdiction in which it is not now so subject.

Representations and Warranties of the Company. The Company represents and

circumstances under which they were made, not misleading, except that the
representations and warranties set forth in this paragraph do not apply to
statements or omissions in the Registration Statement or the Prospectus based
upon information relating to any Underwriter furnished to the Company in writing
by such Underwriter through you expressly for use therein.

               (c) Each preliminary prospectus filed as part of the registration
statement as originally filed or as part of any amendment thereto, or filed

               (d) The Company has been duly incorporated, is validly existing
as a corporation in good standing under the laws of the State of Delaware and
has the corporate power and authority to carry on its business as described in
the Prospectus and to own, lease and operate its properties, and is duly
qualified and is in good standing as a foreign corporation authorized to do
business in each jurisdiction in which the nature of its business or its
ownership or leasing of property requires such qualification, except where the

business, prospects, financial condition or results of operations of the
Company. The Company has no subsidiaries.

               (e) There are no outstanding subscriptions, rights, warrants,

have been duly authorized and validly issued and are fully paid, non-assessable

legal matters to the description thereof contained in the Prospectus.

               (h) The Company is not in violation of its respective charter or
by-laws or in default in the performance of any obligation, agreement, covenant
or condition contained in any indenture, loan agreement, mortgage, lease or
other agreement or instrument that is material to the Company, to which the

               (i) The execution, delivery and performance of this Agreement by
the Company, the compliance by the Company with all the provisions hereof and
the consummation of the transactions contemplated hereby will not (i) require
any consent,


                                       -9-

<PAGE>   10

approval, authorization or other order of, or qualification with, any court or
governmental body or agency (except such as may be required under the securities
or Blue Sky laws of the various states), (ii) conflict with or constitute a
breach of any of the terms or provisions of, or a default under, the charter or
by-laws of the Company or any indenture, loan agreement, mortgage, lease or
other agreement or instrument that is material to the Company, to which the
Company is a party or by which the Company or its property is bound, (iii)
violate or conflict with any applicable law or any rule, regulation, judgment,
order or decree of any court or any governmental body or agency having
jurisdiction over the Company, or its property or (iv) result in the suspension,
termination or revocation of any Authorization (as defined below) of the Company
or any other impairment of the rights of the holder of any such Authorization.

               (j) There are no legal or governmental proceedings pending or
threatened to which the Company is or could be a party or to which any of its
property is or could be subject that are required to be described in the
Registration Statement or the Prospectus and are not so described; nor are there
any statutes, regulations, contracts or other documents that are required to be
described in the Registration Statement or the Prospectus or to be filed as
exhibits to the Registration Statement that are not so described or filed as
required.

               (k) The Company has not violated any foreign, federal, state or
local law or regulation relating to the protection of human health and safety,
the environment or hazardous or toxic substances or wastes, pollutants or
contaminants ("Environmental Laws"), any provisions of the Employee Retirement
Income Security Act of 1974, as amended, or any provisions of the Foreign
Corrupt Practices Act, or the rules and regulations promulgated thereunder,
except for such violations which, singly or in the aggregate, would not have a
material adverse effect on the business, prospects, financial condition or
results of operation of the Company.

               (l) The Company has such permits, licenses, consents, exemptions,
franchises, authorizations and other approvals (each, an "Authorization") of,
and has made all filings with and notices to, all governmental or regulatory
authorities and self-regulatory organizations and all courts and other
tribunals, including, without limitation, under any applicable Environmental
Laws, as are necessary to own, lease, license and operate its properties and to
conduct its business, except where the failure to have any such Authorization or
to make any such filing or notice would not, singly or in the aggregate, have a
material adverse effect on the business, prospects, financial condition or
results of operations of the Company. Notwithstanding the foregoing, the term
"Authorizations" shall not, for purposes hereof, include U.S. Food and Drug
Administration and other governmental or private medical device regulatory
approvals or certifications (collectively, "Device Approvals"), and, with
respect to Device Approvals, the Company represents that its current Device
Approval status is as set forth in the


                                      -10-

<PAGE>   11

Prospectus. Each such Device Approval that the Prospectus discloses that the
Company has obtained ("Obtained Device Approval") and each such Authorization is
valid and in full force and effect and the Company is in compliance with all the
terms and conditions thereof and with the rules and regulations of the
authorities and governing bodies having jurisdiction with respect thereto; and
no event has occurred (including, without limitation, the receipt of any notice
from any authority or governing body) which allows or, after notice or lapse of
time or both, would allow, revocation, suspension or termination of any such
Obtained Device Approval or Authorization or results or, after notice or lapse
of time or both, would result in any other impairment of the rights of the
holder of any such Obtained Device Approval or Authorization; and such Obtained
Device Approval or Authorizations contain no restrictions that are burdensome to
the Company; except where such failure to be valid and in full force and effect
or to be in compliance, the occurrence of any such event or the presence of any
such restriction would not, singly or in the aggregate, have a material adverse
effect on the business, prospects, financial condition or results of operations
of the Company.

               (m) There are no costs or liabilities associated with
Environmental Laws (including, without limitation, any capital or operating
expenditures required for clean-up, closure of properties or compliance with
Environmental Laws or any Authorization, any related constraints on operating
activities and any potential liabilities to third parties) which would, singly
or in the aggregate, have a material adverse effect on the business, prospects,
financial condition or results of operations of the Company.

               (n) The Company owns or possesses, or can acquire on reasonable
terms, all patents, patent rights, licenses, inventions, copyrights, know-how
(including trade secrets and other unpatented and/or unpatentable proprietary or
confidential information, systems or procedures), trademarks, service marks and
trade names ("intellectual property") currently employed by it in connection
with the business now operated by the Company except where the failure to own or
possess or otherwise be able to acquire such intellectual property would not,
singly or in the aggregate, have a material adverse effect on the business,
prospects, financial condition or results of operation of the Company; and the
Company has not received any notice of infringement of or conflict with asserted
rights of others with respect to any of such intellectual property which, singly
or in the aggregate, if the subject of an unfavorable decision, ruling or
finding, would have a material adverse effect on the business, prospects,
financial condition or results of operation of the Company.

               (o) The Company is insured by insurers of recognized financial
responsibility against such losses and risks and in such amounts as are prudent
and customary in the businesses in which it is engaged; and the Company (i) has
not received notice from any insurer or agent of such insurer that substantial
capital improvements or other material expenditures will have to be made in
order to continue such insurance and


                                        -11-

<PAGE>   12

(ii) has no reason to believe that it will not be able to renew its existing
insurance coverage as and when such coverage expires or to obtain similar
coverage from similar insurers at a cost that would not have a material adverse
effect on the business, prospects, financial conditions or results of operation
of the Company.

               (p) This Agreement has been duly authorized, executed and
delivered by the Company.

               (q) McGladrey & Pullen, LLP are independent public accountants
with respect to the Company as required by the Act.

               (r) The consolidated financial statements included in the
Registration Statement and the Prospectus (and any amendment or supplement
thereto), together with related schedules and notes, present fairly the
consolidated financial position, results of operations and changes in financial
position of the Company on the basis stated therein at the respective dates or
for the respective periods to which they apply; such statements and related
schedules and notes have been prepared in accordance with generally accepted
accounting principles consistently applied throughout the periods involved,
except as disclosed therein; the supporting schedules, if any, included in the
Registration Statement present fairly in accordance with generally accepted
accounting principles the information required to be stated therein; and the
other financial and statistical information and data set forth in the
Registration Statement and the Prospectus (and any amendment or supplement
thereto) are, in all material respects, accurately presented and prepared on a
basis consistent with such financial statements and the books and records of the
Company.

               (s) The Company is not and, after giving effect to the offering
and sale of the Shares and the application of the proceeds thereof as described
in the Prospectus, will not be, an "investment company" as such term is defined
in the Investment Company Act of 1940, as amended.

               (t) There are no contracts, agreements or understandings between
the Company and any person granting such person the right to require the Company
to file a registration statement under the Act with respect to any securities of
the Company, except as described in the Registration Statement, or to require
the Company to include such securities with the Shares registered pursuant to
the Registration Statement, except as have been waived prior to the date of this
Agreement.

               (u) Since the respective dates as of which information is given
in the Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement), (i)
there has not occurred any material adverse change or any development involving
a prospective material adverse


                                      -12-

<PAGE>   13

change in the condition, financial or otherwise, or the earnings, business,
management or operations of the Company, (ii) there has not been any material
adverse change or any development involving a prospective material adverse
change in the capital stock or in the long-term debt of the Company and (iii)
the Company has not incurred any material liability or obligation, direct or
contingent.

               (v) Each certificate signed by any officer of the Company and
delivered to the Underwriters or counsel for the Underwriters shall be deemed to
be a representation and warranty by the Company to the Underwriters as to the
matters covered thereby.

               Section 7. Indemnification. (a) The Company agrees to indemnify
and hold harmless each Underwriter, its directors, its officers and each person,
if any, who controls any Underwriter within the meaning of Section 15 of the Act
or Section 20 of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), from and against any and all losses, claims, damages, liabilities and
judgments (including, without limitation, any legal or other expenses incurred
in connection with investigating or defending any matter, including any action,
that could give rise to any such losses, claims, damages, liabilities or
judgments) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement (or any amendment
thereto), the Prospectus (or any amendment or supplement thereto) or any
preliminary prospectus, or caused by 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, except insofar as such losses, claims,
damages, liabilities or judgments are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to any Underwriter furnished in writing to the Company by such Underwriter
through you expressly for use therein; provided, however, that the foregoing
indemnity agreement with respect to any preliminary prospectus shall not inure
to the benefit of any Underwriter who failed to deliver a Prospectus (as then
amended or supplemented, provided by the Company to the several Underwriters in
the requisite quantity and on a timely basis to permit proper delivery on or
prior to the Closing Date) to the person asserting any losses, claims, damages
and liabilities and judgments caused by any untrue statement or alleged untrue
statement of a material fact contained in any preliminary prospectus, or caused
by 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, if
such material misstatement or omission or alleged material misstatement or
omission was cured in such Prospectus and such Prospectus was required by law to
be delivered at or prior to the written confirmation of sale to such person.

               (b) Each Underwriter agrees, severally and not jointly, to
indemnify and hold harmless the Company, its directors, its officers who sign
the Registration Statement and each person, if any, who controls the Company
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act,
to the same extent as the foregoing indemnity


                                      -13-

<PAGE>   14

from the Company to such Underwriter but only with reference to information
relating to such Underwriter furnished in writing to the Company by such
Underwriter through you expressly for use in the Registration Statement (or any
amendment thereto), the Prospectus (or any amendment or supplement thereto) or
any preliminary prospectus.

               (c) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying party") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 7(a) and 7(b), the Underwriter shall not be required to assume
the defense of such action pursuant to this Section 7(c), but may employ
separate counsel and participate in the defense thereof, but the fees and
expenses of such counsel, except as provided below, shall be at the expense of
such Underwriter). Any indemnified party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of the indemnified party
unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) for all indemnified parties and all such fees and
expenses shall be reimbursed as they are incurred. Such firm shall be designated
in writing by Donaldson, Lufkin & Jenrette Securities Corporation and shall be
reasonably acceptable to the Company, in the case of parties indemnified
pursuant to Section 7(a), and by the Company, in the case of parties indemnified
pursuant to Section 7(b). The indemnifying party shall indemnify and hold
harmless the indemnified party from and against any and all losses, claims,
damages, liabilities and judgments by reason of any settlement of any action (i)
effected with its written consent or (ii) effected without its written consent
if the settlement is entered into more than twenty business days after the
indemnifying party shall have received a request from the indemnified party for
reimbursement for the fees and expenses of counsel (in any case where such fees
and expenses are at the expense of


                                        -14-

<PAGE>   15

the indemnifying party) and, prior to the date of such settlement, the
indemnifying party shall have failed to comply with such reimbursement request.
No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement or compromise of, or consent to the
entry of judgment with respect to, any pending or threatened action in respect
of which the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims that
are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.

               (d) To the extent the indemnification provided for in this
Section 7 is unavailable to an indemnified party or insufficient in respect of
any losses, claims, damages, liabilities or judgments 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 and judgments (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 Shares or (ii) if the allocation provided by clause 7(d)(i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause 7(d)(i) above but also the
relative fault of the Company on the one hand and the Underwriters on the other
hand in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or judgments, 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 (after deducting
underwriting discounts and commissions, but before deducting expenses) received
by the Company, and the total underwriting discounts and commissions received by
the Underwriters, bear to the total price to the public of the Shares, in each
case as set forth in the table on the cover page of the Prospectus. 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 or the omission or alleged omission
to state a material fact relates to information supplied by the Company or the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

               The Company and the Underwriters agree that it would not be just
and equitable if contribution pursuant to this Section 7(d) were determined by
pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an


                                      -15-

<PAGE>   16

indemnified party as a result of the losses, claims, damages, liabilities or
judgments referred to in the immediately preceding paragraph shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
incurred by such indemnified party in connection with investigating or defending
any matter, including any action, that could have given rise to such losses,
claims, damages, liabilities or judgments. Notwithstanding the provisions of
this Section 7, no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Shares underwritten
by it and distributed to the public were offered to the public exceeds the
amount of any damages which such Underwriter has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission. 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 Underwriters'
obligations to contribute pursuant to this Section 7(d) are several in
proportion to the respective number of Shares purchased by each of the
Underwriters hereunder and not joint.

               (e) The remedies provided for in this Section 7 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.

               Section 8. Indemnification of QIU. (a) The Company agrees to
indemnify and hold harmless the QIU, its directors, its officers and each
person, if any, who controls the QIU within the meaning of Section 15 of the Act
or Section 20 of the Exchange Act, from and against any and all losses, claims,
damages, liabilities and judgments (including, without limitation, any legal or
other expenses incurred in connection with investigating or defending any
matter, including any action, that could give rise to any such losses, claims,
damages, liabilities or judgments) related to, based upon or arising out of (i)
any untrue statement or alleged untrue statement of a material fact contained in
the Registration Statement (or any amendment thereto), the Prospectus (or any
amendment or supplement thereto) or any preliminary prospectus, 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 (ii) the
QIU's activities as QIU under its engagement pursuant to Section 2 hereof,
except in the case of this clause (ii) insofar as any such losses, claims,
damages, liabilities or judgments are found in a final judgment by a court of
competent jurisdiction, not subject to further appeal, to have resulted solely
from the willful misconduct or gross negligence of the QIU.

               (b) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a) (the "QIU
Indemnified Party"), the QIU Indemnified Party shall promptly notify the Company
in writing and the Company shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the QIU Indemnified Party

payment of all fees and expenses of such counsel, as incurred. Any QIU
Indemnified Party shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the fees and expenses of such
counsel shall be at the expense of the QIU Indemnified Party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the Company, (ii) the Company shall have failed to assume the defense of such
action or employ counsel reasonably satisfactory to the QIU Indemnified Party or
(iii) the named parties to any such action (including any impleaded parties)
include both the QIU Indemnified Party and the Company, and the QIU Indemnified
Party shall have been advised by such counsel that there may be one or more
legal defenses available to it which are different from or additional to those
available to the Company (in which case the Company shall not have the right to
assume the defense of such action on behalf of the QIU Indemnified Party). In
any such case, the Company shall not, in connection with any one action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
fees and expenses of more than one separate firm of attorneys (in addition to
any local counsel) for all QIU Indemnified Parties, which firm shall be
designated by the QIU, and all such fees and expenses shall be reimbursed as
they are incurred. The Company shall indemnify and hold harmless the QIU
Indemnified Party from and against any and all losses, claims, damages,
liabilities and judgments by reason of any settlement of any action (i) effected
with its written consent or (ii) effected without its written consent if the
settlement is entered into more than twenty business days after the Company
shall have received a request from the QIU Indemnified Party for reimbursement
for the fees and expenses of counsel (in any case where such fees and expenses
are at the expense of the Company) and, prior to the date of such settlement,
the Company shall have failed to comply with such reimbursement request. The
Company shall not, without the prior written consent of the QIU Indemnified
Party, effect any settlement or compromise of, or consent to the entry of
judgment with respect to, any pending or threatened action in respect of which
the QIU Indemnified Party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the QIU Indemnified
Party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the QIU Indemnified Party from all liability on claims
that are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the QIU Indemnified Party.

               (c) To the extent the indemnification provided for in this
Section 8 is unavailable to a QIU Indemnified Party or insufficient in respect
of any losses, claims, damages, liabilities or judgments referred to therein,
then the Company, in lieu of indemnifying such QIU Indemnified Party, shall
contribute to the amount paid or payable by such QIU Indemnified Party as a
result of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the QIU on the other hand from the offering of the


                                        -17-

<PAGE>   18

Shares or (ii) if the allocation provided by clause 8(c)(i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause 8(c)(i) above but also the
relative fault of the Company on the one hand and the QIU on the other hand in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and the QIU 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 as set forth in the table on the cover page of
the Prospectus, and the fee received by the QIU pursuant to Section 2 hereof,
bear to the sum of such total net proceeds and such fee. The relative fault of
the Company on the one hand and the QIU on the other hand shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the QIU and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission and whether the QIU's activities as QIU under
its engagement pursuant to Section 2 hereof involved any willful misconduct or
gross negligence on the part of the QIU.

               The Company and the QIU agree that it would not be just and
equitable if contribution pursuant to this Section 8(c) were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by a QIU Indemnified Party as a result of
the losses, claims, damages, liabilities or judgments referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such QIU
Indemnified Party in connection with investigating or defending any matter,
including any action, that could have given rise to such losses, claims,
damages, liabilities or judgments. 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.

               (d) The remedies provided for in this Section 8 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any QIU Indemnified Party at law or in equity.

               Section 9. Conditions of Underwriters' Obligations. Conditions of
Underwriters Obligations. The several obligations of the Underwriters to
purchase the Firm Shares under this Agreement are subject to the satisfaction of
each of the following conditions:



                                      -18-

<PAGE>   19

               (a) All the representations and warranties of the Company
contained in this Agreement shall be true and correct on the Closing Date with
the same force and effect as if made on and as of the Closing Date.

               (b) If the Company is required to file a Rule 462(b) Registration
Statement after the effectiveness of this Agreement, such Rule 462(b)
Registration Statement shall have become effective by 10:00 P.M., New York City
time, on the date of this Agreement; and no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been commenced or shall be pending
before or contemplated by the Commission.

               (c) You shall have received on the Closing Date a certificate
dated the Closing Date, signed by David H. Maupin and Randal L. Owens, in their
capacities as the President and Chief Executive Officer and Vice President of
Finance and Chief Financial Officer of the Company, confirming the matters set
forth in Sections 6(u), 9(a) and 9(b) and that the Company has complied with all
of the agreements and satisfied all of the conditions herein contained and
required to be complied with or satisfied by the Company on or prior to the
Closing Date.

               (d) Since the respective dates as of which information is given
in the Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement), (i)
there shall not have occurred any change or any development involving a
prospective change in the condition, financial or otherwise, or the earnings,
business, management or operations of the Company, (ii) there shall not have
been any change or any development involving a prospective change in the capital
stock or in the long-term debt of the Company and (iii) the Company shall not
have incurred any liability or obligation, direct or contingent, the effect of
which, in any such case described in clause 9(d)(i), 9(d)(ii) or 9(d)(iii), in
your judgment, is material and adverse and, in your judgment, makes it
impracticable to market the Shares on the terms and in the manner contemplated
in the Prospectus.

               (e) You shall have received on the Closing Date an opinion
(satisfactory to you and counsel for the Underwriters), dated the Closing Date,
of Wilson Sonsini Goodrich & Rosati, counsel for the Company, to the effect
that:

               (i) the Company has been duly incorporated, is validly existing
        as a corporation in good standing under the laws of the State of
        Delaware and has the corporate power and authority to carry on its
        business as described in the Prospectus and to own, lease and operate
        its properties;

               (ii) the Company is duly qualified and is in good standing as a
        foreign corporation authorized to do business in each jurisdiction in
        which the nature of


                                      -19-

<PAGE>   20

        its business or its ownership or leasing of property requires such
        qualification, except where the failure to be so qualified would not
        have a material adverse effect on the business, prospects, financial
        condition or results of operations of the Company;

               (iii) all the outstanding shares of capital stock of the Company
        have been duly authorized and validly issued and are fully paid,
        non-assessable and not subject to any preemptive or similar rights;

               (iv) the Shares have been duly authorized and, when issued and
        delivered to the Underwriters against payment therefor as provided by
        this Agreement, will be validly issued, fully paid and non-assessable,
        and the issuance of such Shares will not be subject to any preemptive or
        similar rights;

               (v) this Agreement has been duly authorized, executed and
        delivered by the Company;

               (vi) the authorized capital stock of the Company conforms as to
        legal matters to the description thereof contained in the Prospectus;

               (vii) the Registration Statement has become effective under the
        Act, no stop order suspending its effectiveness has been issued and no
        proceedings for that purpose are, to the best of such counsel's
        knowledge after due inquiry, pending before or contemplated by the
        Commission;

               (viii) the statements under the captions "Risk Factors--Lack of
        Regulatory Approvals", "Business--Government Regulation", "Certain
        Transactions", "Description of Capital Stock", "Shares Eligible for
        Future Sale" and "Underwriting" in the Prospectus and Items 14 and 15 of
        Part II of the Registration Statement, insofar as such statements
        constitute a summary of the legal matters, documents or proceedings
        referred to therein, fairly present the information called for with
        respect to such legal matters, documents and proceedings;

               (ix) the Company is not in violation of its certificate of
        incorporation or by-laws;

               (x) the execution, delivery and performance of this Agreement by
        the Company, the compliance by the Company with all the provisions
        hereof and the consummation of the transactions contemplated hereby will
        not (A) require any consent, approval, authorization or other order of,
        or qualification with, any court or governmental body or agency (except
        such as may be required under the


                                        -20-

<PAGE>   21

        securities or Blue Sky laws of the various states), (B) conflict with or
        constitute a breach of any of the terms or provisions of, or a default
        under, the certificate of incorporation or by-laws of the Company or any
        indenture, loan agreement, mortgage, lease or other agreement or
        instrument that is material to the Company to which the Company is a
        party or by which the Company or property is bound, (C) violate or
        conflict with any applicable law or any rule, regulation, judgment,
        order or decree of any court or any governmental body or agency having
        jurisdiction over the Company, or its property or (D) result in the
        suspension, termination or revocation of any Authorization of the
        Company or any other impairment of the rights of the holder of any such
        Authorization;

               (xi) after due inquiry, such counsel does not know of any legal
        or governmental proceedings pending or threatened to which the Company
        is a party or to which any of its respective property is subject that
        are required to be described in the Registration Statement or the
        Prospectus and are not so described, or of any statutes, regulations,
        contracts or other documents that are required to be described in the
        Registration Statement or the Prospectus or to be filed as exhibits to
        the Registration Statement that are not so described or filed as
        required;

               (xii) the Company is not and, after giving effect to the offering
        and sale of the Shares and the application of the proceeds thereof as
        described in the Prospectus, will not be, an "investment company" as
        such term is defined in the Investment Company Act of 1940, as amended;
        and

               (xiii) to the best of such counsel's knowledge after due inquiry,
        there are no contracts, agreements or understandings between the Company
        and any person granting such person the right to require the Company to
        file a registration statement under the Act with respect to any
        securities of the Company, except as described in the Registration
        Statement, or to require the Company to include such securities with the
        Shares registered pursuant to the Registration Statement, except as have
        been waived prior to the date of this Agreement.

Such counsel shall state that (except for financial statements and schedules and
other financial data derived therefrom as to which such counsel need express no
opinion) the Registration Statement and the Prospectus comply as to form with
the Act. In addition, such counsel shall also state that such counsel has
participated in the preparation of the Registration Statement and the
Prospectus, involving, among other things, review and discussion of the contents
thereof, discussion and inquiries concerning various legal matters and the
review of certain records, documents and proceedings, and participation in
conferences with certain officers and other representatives of the Company,
including its independent auditors, and with the Underwriters and their counsel
at which the contents of the Registration Statement and the Prospectus were
discussed, but without


                                      -21-

<PAGE>   22

independent check or verification of the accuracy or completeness of such
information, except as specified in such counsel's opinion. On the basis of such
consideration, review and discussion, but without independent check or
verification of the accuracy or completeness of such information, nothing has
come to our attention which causes such counsel to believe (A) that (except for
financial statements and schedules and other financial data derived therefrom
included therein as to which such counsel need express no opinion) the
Registration Statement and the Prospectus included therein at the time the
Registration Statement 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 (B) that (except
for financial statements and schedules and other financial data derived
therefrom included therein as to which such counsel need express no opinion) the
Prospectus on the Closing Date contains any untrue statement of a material fact
or omits to state a material fact necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.


               The opinion of Wilson Sonsini Goodrich & Rosati described in
Section 9(e) above shall be rendered to you at the request of the Company and
shall so state therein.

               (f) You shall have received on the Closing Date an opinion
(satisfactory to you and counsel for the Underwriters), dated the Closing Date,
of Lahive &Cockfield, LLP, patent counsel for the Company, to the effect that:

               (i) the statements under the caption "Business - Patents and
        Proprietary Rights" in the Prospectus, insofar as such statements
        constitute a summary of the legal matters, documents or proceedings
        referred to therein, fairly present the information called for with
        respect to such legal matters, documents and proceedings; and

               (ii) such counsel is not aware that the Company lacks ownership
        or possession or cannot acquire on reasonable terms, all patents, patent
        rights, licenses, inventions, copyrights, know-how (including trade
        secrets and other unpatented and/or unpatentable proprietary or
        confidential information, systems or procedures), trademarks, service
        marks and trade names ("intellectual property") currently employed by it
        in connection with the business now operated by the Company except as
        described in the Registration Statement and Prospectus and except where
        the failure to own or possess or otherwise be able to acquire such
        intellectual property would not, singly or in the aggregate, have a
        material adverse effect on the business, prospects, financial condition
        or results of operation of the Company; and, to the best of such
        counsel's knowledge after due


                                      -22-

<PAGE>   23

        inquiry, the Company has not received any notice of infringement of or
        conflict with asserted rights of others with respect to any of such
        intellectual property which, singly or in the aggregate, if the subject
        of an unfavorable decision, ruling or finding, would have a material
        adverse effect on the business, prospects, financial condition or
        results of operations of the Company.

        Such counsel shall also state that although they have not independently
verified the statements contained in the Registration Statement and the
Prospectus under the caption "Risk Factors -- Dependence on Patents and
Proprietary Technology" and "Business --- Patents and Property Rights," nothing
has come to their attention that leaves them to believe that, at the time the
Registration Statement became effective or at the Closing Date, the Registration
Statement and the Prospectus under the captions "Risk Factors ---Dependence on
Patents and Propriety Technology" and "Business -- Patents and Proprietary
Rights" contain any untrue statement of a material fact or omit to state a
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

               The opinion of Lahive & Cockfield, LLP described in Section 9(f)
above shall be rendered to you at the request of the Company and shall so state
therein.

               (g) You shall have received on the Closing Date an opinion, dated
the Closing Date, of Sullivan & Cromwell, counsel for the Underwriters, as to
the matters referred to in Sections 9(e)(iv), 9(e)(v), 9(e)(viii) (but only with
respect to the statements under the caption "Description of Capital Stock" and
"Underwriting") and 9(e)(xvi).

               In giving such opinions with respect to the matters covered by
Section 9(e)(xvi) counsel for the Company and counsel for the Underwriters may
state that their opinion and belief are based upon their participation in the
preparation of the Registration Statement and Prospectus and any amendments or
supplements thereto and review and discussion of the contents thereof, but are
without independent check or verification except as specified.

               (h) You shall have received, on each of the date hereof and the
Closing Date, a letter dated the date hereof or the Closing Date, as the case
may be, in form and substance satisfactory to you, from McGladrey & Pullen, LLP,
independent public accountants, containing the information and statements of the
type ordinarily included in accountants' "comfort letters" to Underwriters with
respect to the financial statements and certain financial information contained
in the Registration Statement and the Prospectus.

               (i) The Company shall have delivered to you the agreements
specified in Section 2 hereof which agreements shall be in full force and effect
on the Closing Date.



                                      -23-

<PAGE>   24

               (j) The Shares shall have been duly listed for quotation on the
Nasdaq National Market.

               (k) The Company shall not have failed on or prior to the Closing
Date to perform or comply with any of the agreements herein contained and
required to be performed or complied with by the Company on or prior to the
Closing Date.

               The several obligations of the Underwriters to purchase any
Additional Shares hereunder are subject to the delivery to you on the applicable
Option Closing Date of such documents as you may reasonably request with respect
to the good standing of the Company, the due authorization and issuance of such
Additional Shares and other matters related to the issuance of such Additional
Shares.

               Section 10. Effectiveness of Agreement and Termination.
Effectiveness of Agreement and Termination. This Agreement shall become
effective upon the execution and delivery of this Agreement by the parties
hereto.

               This Agreement may be terminated at any time on or prior to the
Closing Date by you by written notice to the Company if any of the following has
occurred: (i) any outbreak or escalation of hostilities or other national or
international calamity or crisis or change in economic conditions or in the
financial markets of the United States or elsewhere that, in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market the
Shares on the terms and in the manner contemplated in the Prospectus, (ii) the
suspension or material limitation of trading in securities or other instruments
on the New York Stock Exchange, the American Stock Exchange or the Nasdaq
National Market or limitation on prices for securities or other instruments on
any such exchange or the Nasdaq National Market, (iii) the suspension of trading
of any securities of the Company on any exchange or in the over-the-counter
market, (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 opinion materially and adversely affects,
or will materially and adversely affect, the business, prospects, financial
condition or results of operations of the Company and makes it impracticable to
market the Shares on the terms and in the manner contemplated in the Prospectus,
(v) the declaration of a banking moratorium by either federal or New York State
authorities or (vi) 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
opinion has a material adverse effect on the financial markets in the United
States.

               If on the Closing Date or on an Option Closing Date, as the case
may be, any one or more of the Underwriters shall fail or refuse to purchase the
Firm Shares or Additional Shares, as the case may be, which it has or they have
agreed to purchase hereunder on such date and the aggregate number of Firm
Shares or Additional Shares, as


                                      -24-

<PAGE>   25

the case may be, which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase is not more than one-tenth of the total number of
Firm Shares or Additional Shares, as the case may be, to be purchased on such
date by all Underwriters, each non-defaulting Underwriter shall be obligated
severally, in the proportion which the number of Firm Shares set forth opposite
its name in Schedule I bears to the total number of Firm Shares which all the
non-defaulting Underwriters have agreed to purchase, or in such other proportion
as you may specify, to purchase the Firm Shares or Additional Shares, as the
case may be, which such defaulting Underwriter or Underwriters agreed but failed
or refused to purchase on such date; provided that in no event shall the number
of Firm Shares or Additional Shares, as the case may be, which any Underwriter
has agreed to purchase pursuant to Section 2 hereof be increased pursuant to
this Section 9 by an amount in excess of one-ninth of such number of Firm Shares
or Additional Shares, as the case may be, without the written consent of such
Underwriter. If on the Closing Date any Underwriter or Underwriters shall fail
or refuse to purchase Firm Shares and the aggregate number of Firm Shares with
respect to which such default occurs is more than one-tenth of the aggregate
number of Firm Shares to be purchased by all Underwriters and arrangements
satisfactory to you and the Company for purchase of such Firm Shares are not
made within 48 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Underwriter and the Company. In any
such case which does not result in termination of this Agreement, either you or
the Company shall have the right to postpone the Closing Date, but in no event
for longer than seven days, in order that the required changes, if any, in the
Registration Statement and the Prospectus or any other documents or arrangements
may be effected. If, on an Option Closing Date, any Underwriter or Underwriters
shall fail or refuse to purchase Additional Shares and the aggregate number of
Additional Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Additional Shares to be purchased on such
date, the non-defaulting Underwriters shall have the option to (i) terminate
their obligation hereunder to purchase such Additional Shares or (ii) purchase
not less than the number of Additional Shares that such non-defaulting
Underwriters would have been obligated to purchase on such date in the absence
of such default. Any action taken under this paragraph shall not relieve any
defaulting Underwriter from liability in respect of any default of any such
Underwriter under this Agreement.

               Section 11. Miscellaneous. Notices given pursuant to any
provision of this Agreement shall be addressed as follows: (i) if to the
Company, to UroSurge, Inc., 2660 Crosspark Road, Coralville, Iowa 52241,
Attention: David H. Maupin, and (ii) if to any Underwriter or to you, to you c/o
Donaldson, Lufkin & Jenrette Securities Corporation, 277 Park Avenue, New York,
New York 10172, Attention: Syndicate Department, or in any case to such other
address as the person to be notified may have requested in writing.

               The respective indemnities, contribution agreements,
representations, warranties and other statements of the Company and the several
Underwriters set forth in or made pursuant to this Agreement shall remain
operative and in full force and effect, and will survive delivery of and payment
for the Shares, regardless of (i) any investigation, or statement as to the
results thereof, made by or on behalf of any Underwriter, the officers or
directors of any Underwriter, any person controlling any Underwriter, any QIU
Indemnified Party, the Company, the officers or directors of the Company or any
person controlling the Company, (ii) acceptance of the Shares and payment for
them hereunder and (iii) termination of this Agreement.

               If for any reason the Shares are not delivered by or on behalf of
the Company as provided herein (other than as a result of any termination of
this Agreement pursuant to Section 9), the Company agrees to reimburse the
several Underwriters for all out-of-pocket expenses (including the fees and
disbursements of counsel) incurred by them. Notwithstanding any termination of
this Agreement, the Company shall be liable for all expenses which it has agreed
to pay pursuant to Section 5(i) hereof. The Company also agrees to reimburse the
several Underwriters, their directors and officers, any persons controlling any
of the Underwriters and the QIU Indemnified Parties for any and all fees and
expenses (including, without limitation, the fees disbursements of counsel)
incurred by them in connection with enforcing their rights hereunder (including,
without limitation, pursuant to Section 7 hereof).

               Except as otherwise provided, this Agreement has been and is made
solely for the benefit of and shall be binding upon the Company, the
Underwriters, the Underwriters' directors and officers, any controlling persons
referred to herein, the QIU Indemnified Parties, the Company's directors and the
Company's officers who sign the Registration Statement and their respective
successors and assigns, all as and to the extent provided in this Agreement, and
no other person shall acquire or have any right under or by virtue of this

       The remaining 5,000,000 shares shall be undesignated Preferred Stock and
may be issued from time to time in one or more series pursuant to a resolution
or resolutions providing for such issue duly adopted by the board of directors
(authority to do so being hereby expressly vested in the board). The board of
directors is further authorized to determine or alter the rights, preferences,
privileges and restrictions granted to or imposed upon any wholly unissued
series of Preferred Stock and to fix the number of shares of any series of
Preferred Stock and the designation of any such series of Preferred Stock. The
board of directors, within the limits and restrictions stated in any resolution
or resolutions of the board of directors originally fixing the number of shares
constituting any series, may increase or decrease (but not below the number of
shares in any such series then outstanding) the number of shares of any series
subsequent to the issue of shares of that series.

       The authority of the board of directors with respect to each such class
or series shall include, without limitation of the foregoing, the right to
determine and fix:

       (i)    the distinctive designation of such class or series and the number
of shares to constitute such class or series;

       (ii)   the rate at which dividends on the shares of such class or series
shall be declared and paid, or set aside for payment, whether dividends at the
rate so determined shall be cumulative or accruing, and whether the shares of
such class or series shall be entitled to any participating or other dividends
in addition to dividends at the rate so determined, and if so, on what terms;

       (iii)  the right or obligation, if any, of the Corporation to redeem
shares of the particular class or series of Preferred Stock and, if redeemable,
the price, terms and manner of such redemption;

       (iv)   the special and relative rights and preferences, if any, and the
amount or amounts per share, which the shares of such class or series of
Preferred Stock shall be entitled to receive upon any voluntary or involuntary
liquidation, dissolution or winding up of the Corporation;

       (v)    the terms and conditions, if any, upon which shares of such class
or series shall be convertible into, or exchangeable for, shares of capital
stock of any other class or series, including the price or prices or the rate or
rates of conversion or exchange and the terms of adjustment, if any;


                                      -2-
<PAGE>   3
       (vi)   the obligation, if any, of the Corporation to retire, redeem or
purchase shares of such class or series pursuant to a sinking fund or fund of a
similar nature or otherwise, and the terms and conditions of such obligation;

       (vii)  voting rights, if any, on the issuance of additional shares of
such class or series or any shares of any other class or series of Preferred
Stock;

       (viii) limitations, if any, on the issuance of additional shares of such
class or series or any shares of any other class or series of Preferred Stock;
and

       (ix)   such other preferences, powers, qualifications, special or
relative rights and privileges thereof as the board of directors of the
Corporation, acting in accordance with this Certificate of Incorporation, may
deem advisable and are not inconsistent with law and the provisions of this
Certificate of Incorporation.

       The corporation shall from time to time in accordance with the laws of
the State of Delaware increase the authorized amount of its Common Stock if at
any time the number of shares of Common Stock remaining unissued and available
for issuance shall not be sufficient to permit conversion of the Preferred
Stock.

       The following is a statement of the designations and the powers,
privileges and rights, and the qualifications, limitations or restrictions
thereof in respect of each class of capital stock of the Corporation.

       A.     COMMON STOCK.

              1.     General. The voting, dividend and liquidation rights of the
holders of the Common Stock are subject to and qualified by the rights of the
holders of the Preferred Stock.

              2.     Voting. The holders of the Common Stock are entitled to one
vote for each share held at all meetings of stockholders (and written actions in
lieu of meetings). There shall be no cumulative voting.

              3.     Dividends. Dividends may be declared and paid on the Common
Stock from funds lawfully available therefor as and when determined by the Board
of Directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.

              4.     Liquidation. Upon the dissolution or liquidation of the
Corporation, whether voluntary or involuntary, holders of Common Stock will be
entitled to receive all assets of the Corporation available for distribution to
its stockholders, subject to any preferential rights of any then outstanding
Preferred Stock.

       B.     PREFERRED STOCK.


                                      -3-
<PAGE>   4
              1.     Dividends. In each fiscal year of the Corporation, the
holders of shares of Preferred Stock shall be entitled to receive, before any
cash dividends shall be declared and paid upon or set aside for the Common Stock
in such fiscal year, when and as declared by the Board of Directors of the
Corporation out of funds legally available for that purpose, dividends payable
in cash in an amount per share for such fiscal year at least equal to the
product of (i) the per share amount, if any, of the cash dividend declared, paid
or set aside for the Common Stock during such fiscal year, multiplied by (ii)
the number of whole shares of Common Stock into which each such share of
Preferred Stock is then convertible. Any cash dividends payable to holders of
shares of Preferred Stock shall be payable pari passu among the holders of
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock,
and in preference and priority to any payment of any cash dividend on the Common
Stock. The right to such dividends shall not be cumulative, and no right shall
accrue to holders of Common Stock or Preferred Stock by reason of the fact that
dividends on said shares are not declared in any prior period.

              2.     Liquidation, Dissolution or Winding Up.

                     (a)    Preferred Stock Preference. In the event of any
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, the holders of Series A Preferred Stock, Series B Preferred Stock
and Series C Preferred Stock shall be entitled to receive on a pari passu basis,
prior and in preference to any distribution of any of the assets or surplus
funds of the Corporation to the holders of Common Stock by reason of their
ownership of such shares, an amount equal to $1.00, $2.00 and $5.00 per share,
respectively, plus an amount equal to any declared but unpaid dividends thereon,
with respect to such liquidation, dissolution or winding up. If the assets and
funds thus distributed among the holders of the Series A Preferred Stock, Series
B Preferred Stock and Series C Preferred Stock shall be insufficient to permit
the payment to such holders of the full aforesaid preferential amount, then the
entire assets and funds of the Corporation legally available for distribution
shall be distributed ratably among the holders of the Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock in proportion to the full
preferential amount each such holder is otherwise entitled to receive.

                     (b)    Remaining Assets. After the payment or irrevocable
setting apart of all preferential amounts required to be paid to the holders of
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
upon the dissolution, liquidation or winding up of the Corporation as set forth
in subsection 2(a) above, the holders of shares of Common Stock then outstanding
shall be entitled to receive the remaining assets and funds of the Corporation
available for distribution to its stockholders.

                     (c)    Consolidation or Merger. The merger or consolidation
of the Corporation into or with another corporation, or the sale of all or
substantially all the assets of the Corporation, in which transaction the
Corporation's stockholders immediately prior to such transaction own immediately
after such transaction less than 50% of the voting securities of the surviving
corporation (or its parent), shall be deemed to be a liquidation, dissolution or
winding up of the Corporation for purposes of this Section 2. The amount deemed
distributed to the holders of Preferred Stock upon any such merger or


                                      -4-
<PAGE>   5
consolidation shall be the cash or the value of the property, rights or
securities distributed to such holders by the acquiring person, firm or other
entity. The value of such property, rights or other securities shall be
determined in good faith by the Board of Directors of the Corporation.

       3.     Voting.

              (a)    General. Each holder of outstanding shares of Preferred
Stock shall be entitled to the number of votes equal to the number of whole
shares of Common Stock into which the shares of Preferred Stock held by such
holder are convertible (as adjusted from time to time pursuant to Section 4
hereof), at each meeting of stockholders of the Corporation (and written actions
of stockholders in lieu of meetings) with respect to any and all matters
presented to the stockholders of the Corporation for their action or
consideration. Except as provided by law or by the provisions of subsection 3(b)
below, the holders of Preferred Stock shall vote together with the holders of
Common Stock as a single class.

              (b)    Board of Directors. Notwithstanding Section 3(a) above, the
holders of Series A Preferred Stock shall be entitled to elect one (1) director
of the Corporation, the holders of Series B Preferred Stock shall be entitled to
elect one (1) director of the Corporation, and the holders of Common Stock and
Preferred Stock, voting together, shall be entitled to elect all remaining
directors of the Corporation. Notwithstanding any bylaw provision to the
contrary, the stockholders entitled to elect a particular director shall be
entitled to remove such director or to fill a vacancy in the seat formerly held
by such director, all in accordance with the applicable provisions of the
Delaware General Corporation Law.

              (c)    General Protective Provisions. In addition to any other
rights provided by law or by this Section 3, so long as there shall be issued
and outstanding a number of shares of Preferred Stock equal to at least 67% of
the total number of shares of Preferred Stock ever issued by the Corporation
(subject to appropriate adjustment in the event of any stock dividend, stock
split, combination or other similar recapitalization affecting such shares), the
Corporation shall not, without first obtaining the affirmative vote or written
consent of the holders of not less than 67% of the then outstanding shares of
Preferred Stock consenting or voting (as the case may be) together as a single
class:

                     (i)    Merge or consolidate into or with any other
corporation or sell all or substantially all of the Corporation's assets;

                     (ii)   Voluntarily or involuntarily liquidate, dissolve or
wind up the Corporation or its business;

                     (iii)  Amend or repeal any provision of, or add any
provision to, the Corporation's Certificate of Incorporation or Bylaws, if such
action would alter or change the preferences, rights, privileges or powers of,
or the restrictions provided for the benefit of, any series of Preferred Stock,
or increase or decrease the number of authorized shares of any series of
Preferred Stock;


                                      -5-
<PAGE>   6
                     (iv)   Authorize or issue any new or existing class or
classes or series of capital stock having any preference or priority as to
amounts distributable upon dissolution, liquidation or winding up of the
Corporation superior to or on a parity with any such preference or priority of
any series of Preferred Stock, or authorize or issue shares of stock of any
class or any bonds, debentures, notes or other obligations convertible into or
exchangeable for, or having option rights to purchase, any shares of stock of
the Corporation having any preference or priority as to amounts distributable
upon dissolution, liquidation or winding up of the Corporation superior to or on
a parity with any such preference or priority of any series of Preferred Stock;

                     (v)    Reclassify any Common Stock into shares having any
preference or priority as to amounts distributable upon dissolution, liquidation
or winding up of the Corporation superior to or on a parity with any such
preference or priority of any series of Preferred Stock; or

                     (vi)   Pay or declare any dividend or distribution on any
shares of its capital stock, or apply any of its assets to the redemption,
retirement, purchase or acquisition, directly or indirectly, through
subsidiaries or otherwise, of any shares of its capital stock (other than in
accordance with the terms of restricted stock or similar agreements with
employees or directors of, or consultants to, the Corporation previously
approved by the Board of Directors).

              (d)    Special Series C Protective Provision. In addition to any
other rights provided by law or by this Section 3, so long as there are any
issued and outstanding shares of Series C Preferred Stock, the Corporation shall
not, without first obtaining the affirmative vote or written consent of the
holders of not less than 75% of the then outstanding shares of Series C
Preferred Stock consenting or voting (as the case may be) together as a separate
class, amend, modify, or repeal any provision of Article Fourth, Section B,
Subsection 2 (Liquidation, Dissolution or Winding Up).

       4.     Optional Conversion. The holders of Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

              (a)    Right to Convert. Each share of Preferred Stock shall be
convertible, at the option of the holder thereof, at any time after the date of
issuance of such share at the office of the Corporation or any transfer agent
for the Preferred Stock. Each share of Preferred Stock shall be convertible into
the number of shares of Common Stock which results from dividing the "Conversion
Price" per share in effect for such series of Preferred Stock at the time of
conversion into the "Conversion Value" per share of such series of Preferred
Stock. The number of shares of Common Stock into which a series of Preferred
Stock is convertible is hereinafter referred to as the "Conversion Rate" for
such series of Preferred Stock. The Conversion Price per share of Series A
Preferred Stock shall initially be $1.00, and the Conversion Value per share of
Series A Preferred Stock shall be $1.00. The Conversion Price per share of
Series B Preferred Stock shall initially be $2.00 and the Conversion Value per
share of Series B Preferred Stock shall be $2.00. The Conversion Price per share
of Series C Preferred Stock shall initially be $5.00 and the Conversion Value
per share of Series C Preferred Stock shall be $5.00. The Conver sion Price of
the Series A Preferred Stock, the Series B Preferred Stock and the Series C
Preferred Stock shall be subject to adjustment as hereinafter provided. In the
event of a liquidation of the Corporation,


                                      -6-
<PAGE>   7
the Conversion Rights shall terminate at the close of business on the first full
day preceding the date fixed for the payment of any amounts distributable on
liquidation to the holders of Series A Preferred Stock, Series B Preferred Stock
and Series C Preferred Stock.

              (b)    Fractional Shares. No fractional shares of Common Stock
shall be issued upon conversion of the Preferred Stock. In lieu of any
fractional shares to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to such fraction multiplied by the then
effective applicable Conversion Price.

              (c)    Mechanics of Conversion.

                     (i)    In order for a holder of Preferred Stock to convert
shares of Preferred Stock into shares of Common Stock, such holder shall
surrender the certificate or certificates for such shares of Preferred Stock, at
the office of the transfer agent for the Preferred Stock (or at the principal
office of the Corporation if the Corporation serves as its own transfer agent),
together with written notice that such holder elects to convert all or any
number of the shares of the Preferred Stock represented by such certificate or
certificates. Such notice shall state such holder's name or the names of the
nominees in which such holder wishes the certificate or certificates for shares
of Common Stock to be issued. If required by the Corporation, certificates
surrendered for conversion shall be endorsed or accompanied by a written
instrument or instruments of transfer, in form satisfactory to the Corporation,
duly executed by the registered holder or his or its attorney duly authorized in
writing. The date of receipt of such certificates and notice by the transfer
agent (or by the Corporation if the Corporation serves as its own transfer
agent) shall be the conversion date ("Conversion Date"). The Corporation shall,
as soon as practicable after the Conversion Date, issue and deliver at such
office to such holder of Preferred Stock, or to his or its nominees, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled, together with cash in lieu of any fraction of a
share.

                     (ii)   The Corporation shall at all times when the
Preferred Stock shall be outstanding, reserve and keep available out of its
authorized but unissued stock, for the purpose of effecting the conversion of
the Preferred Stock, such number of its duly authorized shares of Common Stock
as shall from time to time be sufficient to effect the conversion of all
outstanding Preferred Stock. Before taking any action which would cause an
adjustment reducing the Conversion Price below the then par value of the shares
of Common Stock issuable upon conversion of the Preferred Stock, the Corporation
will take any corporate action which may, in the opinion of its counsel, be
necessary in order that the Corporation may validly and legally issue fully paid
and nonassessable shares of Common Stock at such adjusted Conversion Price.

                     (iii)  Upon any such conversion, no adjustment to the
Conversion Price shall be made for any accrued and unpaid dividends, if any, on
the Preferred Stock surrendered for conversion or on the Common Stock delivered
upon conversion.

                     (iv)   All shares of Preferred Stock which shall have been
surrendered for conversion as herein provided shall no longer be deemed to be
outstanding and all rights with respect


                                      -7-
<PAGE>   8
to such shares, including the rights, if any, to receive notices and to vote,
shall immediately cease and terminate on the Conversion Date, except only the
right of the holders thereof to receive shares of Common Stock in exchange
therefor and payment of any declared and unpaid dividends thereon. Any shares of
Preferred Stock so converted shall be retired and canceled and shall not be
reissued, and the Corporation may from time to time take such appropriate action
as may be necessary to reduce the authorized Preferred Stock accordingly.

              (d)    Adjustments to Conversion Price for Diluting Issues.

                     (i)    Special Definitions. For purposes of this Article
FOURTH, the following definitions shall apply:

                            (A)    "Option" shall mean rights, options or

                            (C)    "Convertible Securities" shall mean any
evidence of indebtedness, shares or other securities directly or indirectly
convertible into or exchangeable for Common Stock.

                            (D)    "Additional Shares of Common Stock" with
respect to the Preferred Stock shall mean all shares of Common Stock issued (or,
pursuant to subsection 4(d)(iii) below deemed to be issued) by the Corporation
after the Filing Date, other than:

                                   (I)    all shares of Common Stock and
Preferred Stock outstanding on the date of filing of this certificate with the
Delaware Secretary of State;

                                   (II)   all shares of Common Stock issued or

                                   (IV)   all shares of Common Stock issued or

adjustment for any stock dividend, stock split, combination or other similar
recapitalization affecting such shares).

                     (ii)   No Adjustment of Conversion Price. No adjustment in
the number of shares of Common Stock into which any series of Preferred Stock is
convertible shall be made, by adjustment in the applicable Conversion Price
thereof: (a) unless the consideration per share (determined pursuant to
subsection 4(d)(v) for an Additional Share of Common Stock issued or deemed to
be issued by the Corporation is less than the Conversion Price for such series
of Preferred Stock in effect on the date of, and immediately prior to, the
issuance of such Additional Share of Common Stock, or (b) if prior to such
issuance, the Corporation receives written notice from the holders of at least
67% of the then outstanding shares of such series of Preferred Stock agreeing
that no such adjustment shall be made as the result of the issuance of
Additional Shares of Common Stock.

                     (iii)  Issue of Securities; Deemed Issue of Additional
Shares of Common Stock. If the Corporation, at any time or from time to time
after the Filing Date for the applicable series of Preferred Stock, shall issue
any Options or Convertible Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or Convertible Securities, then the maximum number of shares of Common
Stock (as set forth in the instrument relating thereto without regard to any
provision 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,
shall be deemed to be Additional Shares of Common Stock issued as of the time of
such issue or, in case such a record date shall have been fixed, as of the close
of business on such record date, provided that Additional Shares of Common Stock
shall not be deemed to have been issued unless the consideration per share
(determined pursuant to subsection 4(d)(v) hereof) of such Additional Shares of
Common Stock would be less than the Conversion Price for such series of
Preferred Stock in effect on the date of and immediately prior to such issue, or
such record date, as the case may be, and provided further that in any such case
in which such Additional Shares of Common Stock are deemed to be issued:

                            (A)    No further adjustment in the Conversion Price
shall be made upon the subsequent issue of Convertible Securities or shares of
Common Stock upon the exercise of such Options or 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 Corporation, or decrease in the number of
shares of Common Stock issuable, upon the exercise, conversion or exchange
thereof, the Conversion Price computed upon the original issue date thereof (or
upon the occurrence of a record date 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


                                      -9-
<PAGE>   10
decrease insofar as it affects such Options or the rights of conversion or
exchange under such Convertible Securities;

                            (C)    No readjustment pursuant to clause (B) above
shall have the effect of increasing the Conversion Price to an amount which
exceeds the lower of (i) the Conversion Price on the original adjustment date,
or (ii) the Conversion Price that would have resulted from any issuance of
Additional Shares of Common Stock between the original adjustment date and such
readjustment date;

                            (D)    Upon the expiration or termination of any
unexercised Option, the Conversion Price shall not be readjusted but the
Additional Shares of Common Stock deemed issued as the result of the original
issue date of such Option shall not be deemed issued for the purposes of any
subsequent adjustment of such Conversion Price; and

                            (E)    In the event of any change in the number of
shares of Common Stock issuable upon the exercise, conversion or exchange of any
Option or Convertible Security, including, but not limited to, a change
resulting from the anti-dilution provisions thereof, the Conversion Price then
in effect shall forthwith be readjusted to such Conversion Price as would have
obtained had the adjustment which was made upon the issuance of such Option or
Convertible Security not exercised or converted prior to such change been made
upon the basis of such change, but no further adjustment shall be made for the
actual issuance of Common Stock upon the exercise or conversion of any such
Option or Convertible Security.

                     (iv)   Adjustment of Conversion Price Upon Issuance of
Additional Shares of Common Stock. In the event the Corporation shall, at any
time after the Filing Date, issue Additional Shares of Common Stock (including
Additional Shares of Common Stock deemed to be issued pursuant to subsection
4(d)(iii), but excluding shares issued as a dividend or distribution as provided
in subsection 4(f) or upon a stock split or combination as provided in
subsection 4(e)), without consideration or for a consideration per share less
than the applicable Conversion Price in effect on the date of and immediately
prior to such issue, then and in such event, such Conversion Price shall be
reduced, concurrently with such issue, to a price (calculated to the nearest
cent) determined by multiplying such Conversion Price by a fraction, (A) the
numerator of which shall be (1) the number of shares of Common Stock outstanding
immediately prior to such issue plus (2) the number of shares of Common Stock
which the aggregate consideration received by the Corporation for the total
number of Additional Shares of Common Stock so issued would purchase at such
Conversion Price; and (B) the denominator of which shall be the number of shares
of Common Stock outstanding immediately prior to such issue plus the number of
such Additional Shares of Common Stock so issued; provided that, for the purpose
of this subsection 4(d)(iv), (i) all shares of Common Stock issuable upon
exercise or conversion of Options or Convertible Securities outstanding
immediately prior to such issue shall be deemed to be outstanding, and (ii) the
number of shares of Common Stock deemed issuable upon conversion of such
outstanding Options and Convertible Securities shall not give effect to any
adjustments to the conversion price or conversion rate of such Options or
Convertible Securities resulting from the issuance of Additional Shares of
Common Stock that is the subject of this calculation.


                                      -10-
<PAGE>   11
        Notwithstanding the foregoing, the applicable Conversion Price shall not
be so reduced at such time if the amount of such reduction would be an amount
less than $.01, but any such amount shall be carried forward and reduction with
respect thereto made at the time of and together with any subsequent reduction
which, together with such amount and any other amount or amounts so carried
forward, shall aggregate $.01 or more.

                     (v)    Determination of Consideration. For purposes of this
subsection 4(d), the consideration received by the Corporation for the issue of
any Additional Shares of Common Stock shall be computed as follows:

                            (A)    Cash and Property: Such consideration shall:

                                   (I)    insofar as it consists of cash, be
computed at the aggregate of cash received by the Corporation, excluding amounts
paid or payable for accrued interest or accrued dividends;

                                   (II)   insofar as it consists of property
other than cash, be computed at the fair market value thereof at the time of
such issue, as determined in good faith by the Board of Directors; and

                                   (III)  in the event Additional Shares of
Common Stock are issued together with other shares or securities or other assets
of the Corporation for consideration which covers both, be the proportion of
such consideration so received, computed as provided in clauses (I) and (II)
above, as determined in good faith by the Board of Directors.

                            (B)    Options and Convertible Securities. The
consideration per share received by the Corporation for Additional Shares of
Common Stock deemed to have been issued pursuant to subsection 4(d)(iii),
relating to Options and Convertible Securities, shall be determined by dividing

                                   (x)    the total amount, if any, received or
receivable by the Corporation as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating the relating thereto,
without regard to any provision contained therein for a subsequent adjustment of
such consideration) payable to the Corporation upon the exercise 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, by

                                   (y)    the maximum number of shares of Common
Stock (as set forth in the instruments relating thereto, without regard to any
provision contained therein for a subsequent adjustment of such number) issuable
upon the exercise of such Options or the conversion or exchange of such
Convertible Securities.


                                      -11-
<PAGE>   12
              (e)    Adjustment for Stock Splits and Combinations. If the
Corporation shall at any time or from time to time after the Filing Date effect
a subdivision of the outstanding Common Stock, the Conversion Price for each
series of Preferred Stock then in effect immediately before that subdivision
shall be proportionately decreased. If the Corporation shall at any time or from
time to time after the Filing Date combine the outstanding shares of Common
Stock, the Conversion Price for each series of Preferred Stock then in effect
immediately before the combination shall be proportionately increased. Any
adjustment under this paragraph shall become effective at the close of business
on the date the subdivision or combination becomes effective.

              (f)    Adjustment for Certain Dividends and Distributions. In the
event the Corporation at any time, or from time to time after the Filing Date,
shall make or issue, or fix a record date for the determination of holders of
Common Stock entitled to receive, a dividend or other distribution payable in
additional shares of Common Stock, then and in each such event the Conversion
Price for each series of Preferred Stock then in effect shall be decreased as of
the time of such issuance or, in the event such a record date shall have been
fixed, as of the close of business on such record date, by multiplying the
Conversion Price then in effect by a fraction:

                     (i)    the numerator of which shall be the total number of
shares of Common Stock issued and outstanding immediately prior to the time of
such issuance or the close of business on such record date, and

                     (ii)   the denominator of which shall be the total number
of shares of Common Stock issued and outstanding immediately prior to the time
of such issuance or the close of business on such record date plus the number of
shares of Common Stock issuable in payment of such dividend or distribution:

provided, however, if such record date shall have been fixed and such dividend
is not fully paid or if such distribution is not fully made on the date fixed
therefor, the Conversion Price shall be recomputed accordingly as of the close
of business on such record date and thereafter the Conversion Price shall be
adjusted pursuant to this paragraph as of the time of actual payment of such
dividends or distributions.

              (g)    Adjustments for Other Dividends and Distributions. In the
event the Corporation at any time or from time to time after the Filing Date
shall make or issue, or fix a record date for the determination of holders of
Common Stock entitled to receive, a dividend or other distribution payable in
securities of the Corporation other than shares of Common Stock, then and in
each such event provision shall be made so that the holders of Preferred Stock
shall receive upon conversion thereof in addition to the number of shares of
Common Stock receivable thereupon, the amount of securities of the Corporation
that they would have received had their Preferred Stock been converted into
Common Stock on the date of such event and had thereafter, during the period
from the date of such event to and including the Conversion Date, retained such
securities receivable by them as aforesaid during such period giving application
to all adjustments called for during such period, under this paragraph with
respect to the rights of the holders of the Preferred Stock.

<PAGE>   13
              (h)    Adjustment for Reclassification Exchange, or Substitution.
If the Common Stock issuable upon the conversion of the Preferred Stock shall be
changed into the same or different number of shares of any class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares or stock dividend provided for
above, or a reorganization, merger, consolidation, or sale of assets provided
for below), then and in each such event the holder of each such share of
Preferred Stock shall have the right thereafter to convert such share into the
kind and amount of shares of stock and other securities and property receivable
upon such reorganization, reclassification, or other change, by holders of the
number of shares of Common Stock into which such shares of Preferred Stock might
have been converted immediately prior to such reorganization, reclassification,
or change, all subject to further adjustment as provided herein.

              (i)    Adjustment for Merger or Reorganization, etc. In case of
any consolidation or merger of the Corporation with or into another corporation
or the sale of all or substantially all of the assets of the Corporation to
another corporation (other than a consolidation, merger or sale which is treated
as a liquidation pursuant to subsection 2(c)), each share of Preferred Stock
shall thereafter be convertible into the kind and amount of shares of stock or
other securities or property to which a holder of the number of shares of Common
Stock of the Corporation deliverable upon conversion of such Preferred Stock
would have been entitled upon such consolidation, merger or sale; and, in such
case, appropriate adjustment (as determined in good faith by the Board of
Directors) shall be made in the application of the provisions in this Section 4
set forth with respect to the rights and interest thereafter of the holders of
the Preferred Stock, to the end that the provisions set forth in this Section 4
(including provisions with respect to changes in and other adjustments of the
Conversion Price) shall thereafter be applicable, as nearly as reasonably may
be, in relation to any shares of stock or other property thereafter deliverable
upon the conversion of the Preferred Stock.

              (j)    No Impairment. The Corporation will not, by amendment of
its Certificate of Incorporation or through any reorganization, transfer of
assets, consolidation, merger, 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 to be observed or performed hereunder by the Corporation, but
will at all times in good faith assist in the carrying out of all the provisions
of this Section 4 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of the
Preferred Stock against impairment. This provision shall not restrict the
Corporation from amending its Certificate of Incorporation in accordance with
the General Corporation Law of the State of Delaware.

              (k)    Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Conversion Price for the Preferred Stock
pursuant to this Section 4, the Corporation at its expense shall promptly
compute such adjustment or readjustment in accordance with the terms hereof and
furnish to each holder of Preferred Stock a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based. The Corporation shall, upon the written
request at any time of any holder of Preferred Stock, furnish or cause to be
furnished to such holder a similar certificate setting forth (i) such
adjustments and readjustments, (ii) the Conversion Price for the series of
Preferred Stock held by such holder then in effect, and (iii) the


                                      -13-
<PAGE>   14
number of shares of Common Stock and the amount, if any, of other property which
then would be received upon the conversion of the Preferred Stock held by such
holder.

              (l)    Notice of Record Date. In the event:

                     (i)    that the Corporation declares a dividend (or any
other distribution) on its Common Stock payable in Common Stock or other
securities of the Corporation;

                     (ii)   that the Corporation subdivides or combines its
outstanding shares of Common Stock;

                     (iii)  of any reclassification of the Common Stock of the
Corporation (other than a subdivision or combination of its outstanding shares
of Common Stock or a stock dividend or stock distribution thereon), or of any
consolidation or merger of the Corporation into or with another corporation, or
of the sale of all substantially all of the assets of the Corporation; or

                     (iv)   of the involuntary or voluntary dissolution,
liquidation or winding up of the Corporation;

then the Corporation shall cause to be filed at its principal office or at the
office of the transfer agent of the Preferred Stock, and shall cause to be
mailed to the holders of the Preferred Stock at their last addresses as shown on
the records of the Corporation or such transfer agent, at least ten days prior
to the record date specified in (A) below or twenty days before the date
specified in (B) below, a notice stating

                            (A)    the record date of such dividend,
distribution, subdivision or combination, or, if record is not to be taken, the
date as of which the holders of Common Stock of record to be entitled to such
dividend, distribution subdivision or combination are to be determined, or

                            (B)    the date on which such reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up is expected
to become effective, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their shares of Common
Stock for securities or other property deliverable upon such reclassification,
consolidation, merger, sale, dissolution or winding up.

       5.     Mandatory Conversion.

              (a)    Mandatory Conversion Time. All outstanding shares of
Preferred Stock shall automatically be converted into shares of Common Stock, at
the then current Conversion Price, upon the earlier (the "Mandatory Conversion
Date") of (i) the closing of the sale of shares of Common Stock at a price of at
least $7.50 per share (subject to appropriate adjustment for stock splits, stock
dividends, combinations and other similar recapitalizations affecting such
shares) in an underwritten public offering pursuant to an effective registration
statement under the Securities Act of 1933, as amended, resulting in at least
$15,000,000 of gross proceeds to the Corporation, or (ii) the date on which
there are issued


                                      -14-
<PAGE>   15
and outstanding a number of shares of Preferred Stock equal to less than 33% of
the total number of shares of Preferred Stock ever issued by the Corporation
(subject to appropriate adjustment for stock splits, stock dividends,
combinations and other similar recapitalizations affecting such shares).

              (b)    Mechanics of Conversion. All holders of record of shares of
Preferred Stock will be given written notice of the Mandatory Conversion Date
and the place designated for mandatory conversion of all such shares of
Preferred Stock pursuant to this Section 5. Such notice need not be given in
advance of the occurrence of the Mandatory Conversion Date. Such notice shall be
sent by first class or registered mail, postage prepaid, to each record holder
of Preferred Stock at such holder's address last shown on the records of the
transfer agent for the Preferred Stock (or the records of the corporation, if it
serves as its own transfer agent). Upon receipt of such notice, each holder of
shares of Preferred Stock shall surrender his or its certificate or certificates
for all such shares to the corporation at the place designated in such notice,
and shall thereafter receive certificates for the number of shares of Common
Stock to which such holder is entitled pursuant to this Section 5. On the
Mandatory Conversion Date, all rights with respect to the Preferred Stock so
converted, including the rights, if any, to receive notices and vote, will
terminate, except only the rights of the holders thereof, upon surrender of
their certificate or certificates therefor, to receive certificates for the
number of shares of Common Stock into which such shares of Preferred Stock have
been converted, and payment of any declared or accrued but unpaid dividends
thereon (all of which shall be deemed to be declared by the Board of Directors
on the Mandatory Conversion Date). If so required by the Corporation,
certificates surrendered for conversion shall be endorsed or accompanied by
written instrument or instruments of transfer, in form satisfactory to the
Corporation, duly executed by the registered holder or by his or its attorney
duly authorized in writing. As soon as practicable after the Mandatory
Conversion Date and the surrender of the certificate or certificates for
Preferred Stock, the Corporation shall cause to be issued and delivered to such
holder, or on his or its written order, a certificate or certificates for the
number of full shares of Common Stock issuable on such conversion in accordance
with the provisions hereof and cash as provided in subsection 4(b) in respect of
any fraction of a share of Common Stock otherwise issuable upon such conversion.

              (c)    Retirement of Shares. All certificates evidencing shares of
Preferred Stock which are required to be surrendered for conversion in
accordance with the provisions hereof shall, from and after the Mandatory
Conversion Date, be deemed to have been retired and cancelled and the shares of
Preferred Stock presented thereby converted into Common Stock for all purposes,
notwithstanding the failure of the holder or holders thereof to surrender such
certificates on or prior to such date. The Corporation may thereafter take such
appropriate action (without the need for stockholder action) as may be necessary
to reduce the authorized Preferred Stock accordingly.

       FIFTH. In furtherance of and not in limitation of powers conferred by
statute, it is further provided:

       1.     Election of directors need not be by written ballot.


                                      -15-
<PAGE>   16
       2.     The Board of Directors is expressly authorized to adopt, amend or
repeal the Bylaws of the Corporation.

       SIXTH. Whenever a compromise or arrangement is proposed between this
Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof, or on the
application of any receiver or receivers appointed for this Corporation under
the provisions of section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this Corporation under the provisions of section 279 of Title 8 of the
Delaware Code order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this Corporation, as the case may
be, to be summoned in such manner as the said court directs. If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this Corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this Corporation, as the case may be,
and also on this Corporation.

       SEVENTH. Except to the extent that the General Corporation Law of
Delaware prohibits the elimination or limitation of liability of directors for
breaches of fiduciary duty, no director of the Corporation shall be personally
liable to the Corporation or its stockholders for monetary damages for any
breach of fiduciary duty as a director, notwithstanding any provision of law
imposing such liability. No amendment to or repeal of this provision shall apply
to or have any effect on the liability or alleged liability of any director of
the Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment.

       EIGHTH. The Corporation shall, to the fullest extent permitted by Section
145 of the General Corporation Law of Delaware, as amended from time to time,
indemnify each person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that he
is or was, or has agreed to become, a director or officer of the Corporation, or
is or was serving, or has agreed to serve, at the request of the Corporation, as
a director, officer or trustee of, or in a similar capacity with, another
Corporation, partnership, joint venture, trust or other enterprise (including
any employee benefit plan), or by reason of any action alleged to have been
taken or omitted in such capacity, against all expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or on his behalf in connection with such action, suit or
proceeding and any appeal therefrom.

       With respect to any action, suit, proceeding or investigation for which
indemnity will or could be sought, the Corporation will be entitled to
participate therein at its own expense and/or to assume the


                                      -16-
<PAGE>   17
defense thereof at its own expense, with legal counsel reasonably acceptable to
the person seeking indemnification.

       In the event that the Corporation does not assume the defense of any
action, suit, proceeding or investigation for which indemnity will or could be
sought, any expenses (including attorneys' fees) incurred by the person seeking
indemnification in defending a civil or criminal action, suit, proceeding or
investigation or any appeal therefrom shall be paid by the Corporation in
advance of the final disposition of such matter upon receipt of an undertaking
by the person indemnified to repay such payment if it is ultimately determined
that such person is not entitled to indemnification under this Article, which
undertaking may be accepted without reference to the financial ability of such
person to make such repayment.

       The Corporation shall not indemnify any such person seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such person unless the initiation thereof was approved by the Board of Directors
of the Corporation.

       The indemnification rights provided in this Article EIGHTH (i) shall not
be deemed exclusive of any other rights to which those indemnified may be
entitled under any law, agreement or vote of stockholders or disinterested
directors or otherwise, and (ii) shall inure to the benefit of the heirs,
executors and administrators of such persons. The Corporation may, to the extent
authorized from time to time by its Board of Directors, grant indemnification
rights to other employees or agents of the Corporation or other persons serving
the Corporation and such rights may be equivalent to, or greater or less than,
those set forth in this Article.

       NINTH. The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute and this Certificate of
Incorporation, and all rights conferred upon stock holders herein are granted
subject to this reservation.

may be issued from time to time in one or more series pursuant to a resolution
or resolutions providing for such issue duly adopted by the board of directors
(authority to do so being hereby expressly vested in the board). The board of
directors is further authorized to determine or alter the rights, preferences,
privileges and restrictions granted to or imposed upon any wholly unissued
series of Preferred Stock and to fix the number of shares of any series of
Preferred Stock and the designation of any such series of Preferred Stock. The
board of directors, within the limits and restrictions stated in any resolution
or resolutions of the board of directors originally fixing the number of shares
constituting any series, may increase or decrease (but not below the number of
shares in any such series then outstanding) the number of shares of any series
subsequent to the issue of shares of that series.

       The authority of the board of directors with respect to each such class
or series shall include, without limitation of the foregoing, the right to
determine and fix:

       (i)    the distinctive designation of such class or series and the number
of shares to constitute such class or series;

       (ii)   the rate at which dividends on the shares of such class or series
shall be declared and paid, or set aside for payment, whether dividends at the
rate so determined shall be cumulative or accruing, and whether the shares of
such class or series shall be entitled to any participating or other dividends
in addition to dividends at the rate so determined, and if so, on what terms;

       (iii)  the right or obligation, if any, of the Corporation to redeem
shares of the particular class or series of Preferred Stock and, if redeemable,
the price, terms and manner of such redemption;

       (iv)   the special and relative rights and preferences, if any, and the
amount or amounts per share, which the shares of such class or series of
Preferred Stock shall be entitled to receive upon any voluntary or involuntary
liquidation, dissolution or winding up of the Corporation;

       (v)    the terms and conditions, if any, upon which shares of such class
or series shall be convertible into, or exchangeable for, shares of capital
stock of any other class or series, including the price or prices or the rate or
rates of conversion or exchange and the terms of adjustment, if any;

       (vi)   the obligation, if any, of the Corporation to retire, redeem or
purchase shares of such class or series pursuant to a sinking fund or fund of a
similar nature or otherwise, and the terms and conditions of such obligation;


                                      -2-

       (vii)  voting rights, if any, on the issuance of additional shares of
such class or series or any shares of any other class or series of Preferred
Stock;

       (viii) limitations, if any, on the issuance of additional shares of such
class or series or any shares of any other class or series of Preferred Stock;
and

       (ix)   such other preferences, powers, qualifications, special or
relative rights and privileges thereof as the board of directors of the
Corporation, acting in accordance with this Certificate of Incorporation, may
deem advisable and are not inconsistent with law and the provisions of this
Certificate of Incorporation.

Delaware, as the Bylaws may provide. The books of the Corporation may be kept
(subject to any provisions contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the

                                   ARTICLE IX

       Holders of stock of any class or series of the Corporation shall not be

for the amendment, repeal or modification of the provisions of Article IX or X
of this Amended and Restated Certificate of Incorporation or Sections 1.3, 1.5
and 2.2(b) of the corporation's Bylaws.

                                   ARTICLE XI

       To the fullest extent permitted by the Delaware General Corporation Law,
a director of the corporation shall not be personally liable to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director. Neither any amendment nor repeal of this Article XI nor the adoption
of any provision of this Certificate of Incorporation inconsistent with this
Article XI, shall eliminate or reduce the effect of this Article XI in respect
of any matter occurring, or any cause of action, suit or claim that, but for
this Article XI, would accrue or arise, prior to such amendment, repeal or
adoption of an inconsistent provision.

                                   ARTICLE XII

       1.     The corporation shall indemnify each of the corporation's
directors and officers in each and every situation where, under Section 145 of
the General Corporation Law of the State of Delaware, as amended from time to
time ("Section 145"), the corporation is permitted or empowered to make such
indemnification. The corporation may, in the sole discretion of the Board of
Directors of the corporation, indemnify any other person who may be indemnified
pursuant to Section 145 to the extent the Board of Directors deems advisable, as
permitted by Section 145. The corporation shall promptly make or cause to be
made any determination required to be made pursuant to Section 145.

       2.     No person shall be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
provided, however, that the foregoing shall not eliminate or limit the liability
of a director (i) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the General Corporation Law of the State of Delaware or (iv) for
any transaction from which the director derived an improper personal benefit. If
the General Corporation Law of the State of Delaware is subsequently amended to
further eliminate or limit the liability of a director, then a director of the
corporation, in addition to the circumstances in which a director is not
personally liable as set forth in the preceding sentence, shall not be liable to
the fullest extent permitted by the amended General Corporation Law of the State
of Delaware. For purposes of this Article XII, "fiduciary duty as a director"
shall include any fiduciary duty arising out of serving at the corporation's
request as a director of another corporation, partnership, joint venture or
other enterprise, and "personal liability to the corporation or its
stockholders" shall include any liability to such other corporation,
partnership, joint venture, trust or other enterprise, and any liability to the
corporation in its capacity as a security holder, joint venturer, partner,
beneficiary, creditor or investor of or in any such other corporation,
partnership, joint venture, trust or other enterprise.

                                    ARTICLE 1

                                  STOCKHOLDERS

        1.1 Place of Meetings. All meetings of stockholders shall be held at
such place within or without the State of Delaware as may be designated from
time to time by the Board of Directors or the President or, if not so
designated, at the registered office of the corporation.

        1.2 Annual Meeting. The annual meeting of stockholders for the election
of directors and for the transaction of such other business as may properly be
brought before the meeting shall be held on a date to be fixed by the Board of
Directors or the President (which date shall not be a legal holiday in the place
where the meeting is to be held) at the time and place to be fixed by the Board
of Directors or the President and stated in the notice of the meeting. If no
annual meeting is held in accordance with the foregoing provisions, the Board of
Directors shall cause the meeting to be held as soon thereafter as convenient.
If no annual meeting is held in accordance with the foregoing provisions, a
special meeting may be held in lieu of the annual meeting, and any action taken
at that special meeting shall have the same effect as if it had been taken at
the annual meeting, and in such case all references in these By-Laws to the
annual meeting of the stockholders shall be deemed to refer to such special
meeting.

        1.3 Special Meetings. Special meetings of stockholders may be called at
any time by the President or by the Board of Directors. Business transacted at
any special meeting of stockholders shall be limited to matters relating to the
purpose or purposes stated in the notice of meeting.

        1.4 Notice of Meetings. Except as otherwise provided by law, written
notice of each meeting of stockholders, whether annual or special, shall be
given not less than 10 nor more than 60 days before the date of the meeting to
each stockholder entitled to vote at such meeting. The notices of all meetings
shall state the place, date and hour of the meeting. The notice of a special
meeting shall state, in addition, the purpose or purposes for which the meeting
is called. If mailed, notice is given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation.

        1.5 Voting List. The officer who has charge of the stock ledger of the
corporation shall prepare, at least 10 days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary




<PAGE>   2

business hours, for a period of at least 10 days prior to the meeting, at a
place within the city where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time of
the meeting, and may be inspected by any stockholder who is present.

        1.6 Quorum. Except as otherwise provided by law, the Certificate of
Incorporation or these By-Laws, the holders of a majority of the shares of the
capital stock of the corporation issued and outstanding and entitled to vote at
the meeting, present in person or represented by proxy, shall constitute a
quorum for the transaction of business.

        1.7 Adjournments. Any meeting of stockholders may be adjourned to any
other time and to any other place at which a meeting of stockholders may be held
under these By-Laws by the stockholders present or represented at the meeting
and entitled to vote, although less than a quorum, or, if no stockholder is
present, by any officer entitled to preside at or to act as Secretary of such
meeting. It shall not be necessary to notify any stockholder of any adjournment
of less than 30 days if the time and place of the adjourned meeting are
announced at the meeting at which adjournment is taken, unless after the
adjournment a new record date is fixed for the adjourned meeting. At the
adjourned meeting, the corporation may transact any business which might have
been transacted at the original meeting.

        1.8 Voting and Proxies. Each stockholder shall have one vote for each
share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
in the Certificate of Incorporation. Each stockholder of record entitled to vote
at a meeting of stockholders, or to express consent or dissent to corporate
action in writing without a meeting, may vote or express such consent or dissent
in person or may authorize another person or persons to vote or act for him by
written proxy executed by the stockholder or his authorized agent and delivered
to the Secretary of the corporation. No such proxy shall be voted or acted upon
after three years from the date of its execution, unless the proxy expressly
provides for a longer period.

        1.9 Action at Meeting. When a quorum is present at any meeting, the
holders of shares of stock representing a majority of the votes cast on a matter
(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of shares of stock of
that class representing a majority of the votes cast on a matter) shall decide
any matter to be voted upon by the stockholders at such meeting, except when a
different vote is required by express provision of law, the Certificate of
Incorporation or these By-laws. When a quorum is present at any meeting, any
election by stockholders shall be determined by a plurality of the votes cast on
the election.

        1.10 Action without Meeting. Any action required or permitted to be
taken at any annual or special meeting of stockholders of the corporation may be
taken without a meeting, without prior notice and without a vote, if a consent
in writing, setting forth the action so taken, is signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote on such



                                      -2-

action were present and voted. Prompt notice of the taking of corporate action
without a meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing.


                                    ARTICLE 2

                                    DIRECTORS

        2.1 General Powers. The business and affairs of the corporation shall be
managed by or under the direction of a Board of Directors, who may exercise all
of the powers of the corporation except as otherwise provided by law or the
Certificate of Incorporation. In the event of a vacancy in the Board of
Directors, the remaining directors, except as otherwise provided by law, may
exercise the powers of the full Board until the vacancy is filled.

        2.2 Number; Election and Qualification. The number of directors which
shall constitute the whole Board of Directors shall be determined by resolution
of the stockholders or the Board of Directors, but in no event shall be less
than one. The number of directors may be decreased at any time and from time to
time either by the stockholders or by a majority of the directors then in
office, but only to eliminate vacancies existing by reason of the death,
resignation, removal or expiration of the term of one or more directors. The
directors shall be elected at the annual meeting of stockholders by such
stockholders as have the right to vote on such election. Directors need not be
stockholders of the corporation.

        2.3 Enlargement of the Board. The number of directors may be increased
at any time and from time to time by the stockholders or by a majority of the
directors then in office.

        2.4 Tenure. Each director shall hold office until the next annual
meeting and until his successor is elected and qualified, or until his earlier
death, resignation or removal.

        2.5 Vacancies. Unless and until filled by the stockholders, any vacancy
in the Board of Directors, however occurring, including a vacancy resulting from
an enlargement of the Board, may be filled by vote of a majority of the
directors then in office, although less than a quorum, or by a sole remaining
director. A director elected to fill a vacancy shall be elected for the
unexpired term of his predecessor in office, and a director chosen to fill a
position resulting from an increase in the number of directors shall hold office
until the next annual meeting of stockholders and until his successor is elected
and qualified, or until his earlier death, resignation or removal.

        2.6 Resignation. Any director may resign by delivering his written
resignation to the corporation at its principal office or to the President or
Secretary. Such resignation shall be effective upon receipt unless it is
specified to be effective at some other time or upon the happening of some other
event.

        2.7 Regular Meetings. Regular meetings of the Board of Directors may be
held without notice at such time and place, either within or without the State
of Delaware, as shall be determined from time to time by the Board of Directors;
provided that any director who is absent when such a determination is made shall
be given notice of the determination. A regular meeting of the Board of
Directors may be held without notice immediately after and at the same place as
the annual meeting of stockholders.

        2.8 Special Meetings. Special meetings of the Board of Directors may be
held at any time and place, within or without the State of Delaware, designated
in a call by the Chairman of the Board, President, two or more directors, or by
one director in the event that there is only a single director in office.

        2.9 Notice of Special Meetings. Notice of any special meeting of
directors shall be given to each director by the Secretary or by the officer or
one of the directors calling the meeting. Notice shall be duly given to each
director (i) by giving notice to such director in person or by telephone at
least 48 hours in advance of the meeting, (ii) by sending a telegram or telex,
or delivering written notice by hand, to his last known business or home address
at least 48 hours in advance of the meeting, or (iii) by mailing written notice
to his last known business or home address at least 72 hours in advance of the
meeting. A notice or waiver of notice of a meeting of the Board of Directors
need not specify the purposes of the meeting.

        2.10 Meetings by Telephone Conference Calls. Directors or any members of
any committee designated by the directors may participate in a meeting of the
Board of Directors or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation by such means shall constitute
presence in person at such meeting.

        2.11 Quorum. A majority of the total number of the whole Board of
Directors shall constitute a quorum at all meetings of the Board of Directors.
In the event one or more of the directors shall be disqualified to vote at any
meeting, then the required quorum shall be reduced by one for each such director
so disqualified; provided, however, that in no case shall less than one-third
(1/3) of the number so fixed constitute a quorum. In the absence of a quorum at
any such meeting, a majority of the directors present may adjourn the meeting
from time to time without further notice other than announcement at the meeting,
until a quorum shall be present.

        2.12 Action at Meeting. At any meeting of the Board of Directors at
which a quorum is present, the vote of a majority of those present shall be
sufficient to take any action, unless a different vote is specified by law, the
Certificate of Incorporation or these By-Laws.

        2.13 Action by Consent. Any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee of the Board of
Directors may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent to the action in writing, and the written
consents are filed with the minutes of proceedings of the Board or committee.

        2.14 Removal. Except as otherwise provided by the General Corporation
Law of Delaware, any one or more or all of the directors may be removed, with or
without cause, by the holders of a majority of the shares then entitled to vote
at an election of directors, except that the directors elected by the holders of
a particular class or series of stock may be removed without cause only by vote
of the holders of a majority of the outstanding shares of such class or series.

        2.15 Committees. The Board of Directors may, by resolution passed by a
majority of the whole Board, designate one or more committees, each committee to
consist of one or more of the directors of the corporation. The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member of a committee, the member or
members of the committee present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member. Any such committee, to the extent
provided in the resolution of the Board of Directors and subject to the
provisions of the General Corporation Law of the State of Delaware, shall have
and may exercise all the powers and authority of the Board of Directors in the
management of the business and affairs of the corporation and may authorize the
seal of the corporation to be affixed to all papers which may require it. Each
such committee shall keep minutes and make such reports as the Board of
Directors may from time to time request. Except as the Board of Directors may
otherwise determine, any committee may make rules for the conduct of its
business, but unless otherwise provided by the directors or in such rules, its
business shall be conducted as nearly as possible in the same manner as is
provided in these By-Laws for the Board of Directors.

        2.16 Compensation of Directors. Directors may be paid such compensation
for their services and such reimbursement for expenses of attendance at meetings
as the Board of Directors may from time to time determine. No such payment shall
preclude any director from serving the corporation or any of its parent or
subsidiary corporations in any other capacity and receiving compensation for
such service.

President, a Secretary, a Treasurer and such other officers with such other
titles as the Board of Directors shall determine, including a Chairman of the

other officers as it may deem appropriate.

        3.2 Election. The President, Treasurer and Secretary shall be elected

other event.

        Any officer may be removed at any time, with or without cause, by vote
of a majority of the entire number of directors then in office.

        Except as the Board of Directors may otherwise determine, no officer who
resigns or is removed shall have any right to any compensation as an officer for
any period following his resigna tion or removal, or any right to damages on
account of such removal, whether his compensation be by the month or by the year
or otherwise, unless such compensation is expressly provided in a duly
authorized written agreement with the corporation.

        3.6 Vacancies. The Board of Directors may fill any vacancy occurring in
any office for any reason and may, in its discretion, leave unfilled for such
period as it may determine any offices other than those of President, Treasurer
and Secretary. Each such successor shall hold office for the unexpired term of
his predecessor and until his successor is elected and qualified, or until his
earlier death, resignation or removal.

the Chairman of the Board, perform the duties and exercise the powers of the
Chairman of the Board and shall perform such other duties and possess such other
powers as may from time to time be vested in him by the Board of Directors.

Board of Directors, have general charge and supervision of the business of the
corporation. Unless otherwise provided by the Board of Directors, he shall
preside at all meetings of the stockholders and, if he is a director, at all

President shall be the Chief Executive Officer of the corporation. The President
shall perform such other duties and shall have such other powers as the Board of
Directors may from time to time prescribe.

or the whole or any part of any unissued balance of the authorized capital stock
of the corporation held in its treasury may be issued, sold, transferred or
otherwise disposed of by vote of the Board of Directors in such manner, for such

        4.5 Record Date. The Board of Directors may fix in advance a date as a
record date for the determination of the stockholders entitled to notice of or
to vote at any meeting of stockholders or to express consent (or dissent) to
corporate action in writing without a meeting, or entitled to receive payment of
any dividend or other distribution or allotment of any rights in respect of any
change, conversion or exchange of stock, or for the purpose of any other lawful
action. Such record date shall not be more than 60 nor less than 10 days before
the date of such meeting, nor more than 60 days prior to any other action to
which such record date relates.

        If no record date is fixed, the record date for determining stockholders
entitled to notice of or to vote at a meeting of stockholders shall be at the
close of business on the day before the day on which notice is given, or, if
notice is waived, at the close of business on the day before the day on which
the meeting is held. The record date for determining stockholders entitled to
express consent to corporate action in writing without a meeting, when no prior
action by the Board of Directors is necessary, shall be the day on which the
first written consent is expressed. The record date for determining stockholders
for any other purpose shall be at the close of business on the day on which the
Board of Directors adopts the resolution relating to such purpose.

        A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

of such notice either in writing signed by the person entitled to such notice or
such person's duly authorized attorney, or by telegraph, cable or any other
available method, whether before, at or after the time stated in such waiver, or
the appearance of such person or persons at such meeting in person or by proxy,

the corporation and any other corporation, partnership, association, or other
organization in which one or more of the directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or a committee of the
Board of Directors which authorizes the contract or transaction or solely
because his or their votes are counted for such purpose, if:

               (1) The material facts as to his relationship or interest and as
        to the contract or transaction are disclosed or are known to the Board
        of Directors or the committee, and the Board or committee in good faith

               (2) The material facts as to his relationship or interest and as
        to the contract or transaction are disclosed or are known to the
        stockholders entitled to vote thereon, and the contract or transaction

               (3) The contract or transaction is fair as to the corporation as
        of the time it is authorized, approved or ratified, by the Board of
        Directors, a committee of the Board of Directors, or the stockholders.

        5.9 Pronouns. All pronouns used in these By-Laws shall be deemed to
refer to the masculine, feminine or neuter, singular or plural, as the identity
of the person or persons may require.

more than thirty (30) days from the date contemplated at the time of the
previous year's proxy state ment, notice by the stockholder to be timely must be
so received a reasonable time before the solicitation is made. To be in proper

                     (i)    the name and address of the stockholder who intends
       to make the nominations or propose the business and, as the case may be,
       of the person or persons to be nominated or of the business to be
       proposed;

                     (ii)   a representation that the stockholder is a holder of
       record of stock of the corporation entitled to vote at such meeting and,
       if applicable, intends to appear in person or by proxy at the meeting to
       nominate the person or persons specified in the notice;

<PAGE>   7
                     (iii)  if applicable, a description of all arrangements or
       understandings between the stockholder and each nominee and any other
       person or persons (naming such person or persons) pursuant to which the
       nomination or nominations are to be made by the stockholder;

                     (iv)   such other information regarding each nominee or
       each matter of business to be proposed by such stockholder as would be
       required to be included in a proxy statement filed pursuant to the proxy
       rules of the Securities and Exchange Commission had the nominee been
       nominated, or intended to be nominated, or the matter been proposed, or
       intended to be proposed by the board of directors; and

                     (v)    if applicable, the consent of each nominee to serve
       as director of the corporation if so elected.

        The chairman of the meeting shall refuse to acknowledge the nomination
of any person or the proposal of any business not made in compliance with the
foregoing procedure.

       1.6    Manner of Giving Notice; Affidavit of Notice. Written notice of
any meeting of stockholders shall be given either personally or by first-class
mail or by telegraphic or other written communication. Notices not personally
delivered shall be sent charges prepaid and shall be addressed to the
stockholder at the address of that stockholder appearing on the books of the
corpo ration or given by the stockholder to the corporation for the purpose of
notice. Notice shall be deemed to have been given at the time when delivered
personally or deposited in the mail or sent by telegram or other means of
written communication.

               An affidavit of the mailing or other means of giving any notice
of any stockholders' meeting, executed by the secretary, assistant secretary or
any transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

       1.7    Quorum. The holders of a majority in voting power of the stock
issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall constitute a quorum at all meetings of the
stockholders for the transaction of business except as otherwise pro vided by
statute or by the certificate of incorporation. If, however, such quorum is not
present or represented at any meeting of the stockholders, then either (i) the
chairman of the meeting or (ii) the stockholders entitled to vote thereat,
present in person or represented by proxy, shall have power to adjourn the
meeting in accordance with Section 1.7 of these bylaws.

              When a quorum is present at any meeting, the vote of the holders
of a majority of the stock having voting power present in person or represented
by proxy shall decide any question brought before such meeting, unless the
question is one upon which, by express provision of the laws of the State of
Delaware or of the certificate of incorporation or these bylaws, a different
vote is required, in which case such express provision shall govern and control
the decision of the question.


                                      -3-
<PAGE>   8
              If a quorum be initially present, the stockholders may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken is approved by a
majority of the stockholders initially constituting the quorum.

       1.8    Adjournments. Any meeting of stockholders may be adjourned to any
other time and place at which a meeting of stockholders may be held under these
bylaws. Unless these bylaws otherwise require, it shall not be necessary to
notify any stockholder of any adjournment of less than 30 days if the time and
place of the adjourned meeting are announced at the meeting at which adjournment
is taken. At the adjourned meeting, the corporation may transact any business
which might have been transacted at the original meeting. If the adjournment is
for more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

       1.9    Voting. The stockholders entitled to vote at any meeting of
stockholders shall be determined in accordance with the provisions of Section
1.11 of these bylaws, subject to the provisions of Sections 217 and 218 of the
General Corporation Law of Delaware (relating to voting rights of fiduciaries,
pledgors and joint owners, and to voting trusts and other voting agreements).

              Except as may be otherwise provided in the certificate of
incorporation or these bylaws, each stockholder shall be entitled to one vote
for each share of capital stock held by such stockholder and stockholders shall
not be entitled to cumulate their votes in the election of directors or with
respect to any matter submitted to a vote of the stockholders.

       1.10   Record Date for Stockholder Notice; Voting. For purposes of
determining the stockholders entitled to notice of any meeting or to vote
thereat, the board of directors may fix, in advance, a record date, which shall
not precede the date upon which the resolution fixing the record date is adopted
by the board of directors and which shall not be more than sixty (60) days nor
less than ten (10) days before the date of any such meeting, and in such event
only stockholders of record on the date so fixed are entitled to notice and to
vote, notwithstanding any transfer of any shares on the books of the corporation
after the record date.


                                      -4-
<PAGE>   9
              If the board of directors does not so fix a record date, the
record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business on the business day
next preceding the day on which notice is given, or, if notice is waived, at the
close of business on the business day next preceding the day on which the
meeting is held.

              A determination of stockholders of record entitled to notice of or
to vote at a meeting of stockholders shall apply to any adjournment of the
meeting unless the board of directors fixes a new record date for the adjourned
meeting, but the board of directors shall fix a new record date if the meeting
is adjourned for more than thirty (30) days from the date set for the original
meeting.

              The record date for any other purpose shall be as provided in
Section 7.1 of these bylaws.

       1.12   Proxies. Every person entitled to vote for directors, or on any
other matter, shall have the right to do so either in person or by one or more
agents authorized by a written proxy signed by the person and filed with the
secretary of the corporation, but no such proxy shall be voted or acted upon
after three (3) years from its date, unless the proxy provides for a longer
period. A proxy shall be deemed signed if the stockholder's name is placed on
the proxy (whether by manual signature, typewriting, telegraphic transmission,
telefacsimile or otherwise) by the stockholder or the stockholder's
attorney-in-fact. The revocability of a proxy that states on its face that it is
irrevocable shall be governed by the provisions of Section 212(e) of the General
Corporation Law of Delaware.

       1.13   Organization. The president, or in the absence of the president,
the chairman of the board, or, in the absence of the president and the chairman
of the board, one of the corporation's vice presidents, shall call the meeting
of the stockholders to order, and shall act as chairman of the meeting. In the
absence of the president, the chairman of the board, and all of the vice
presidents, the stockholders shall appoint a chairman for such meeting. The
chairman of any meeting of stockholders shall determine the order of business
and the procedures at the meeting, including such matters as the regulation of
the manner of voting and the conduct of business. The secretary of the
corporation shall act as secretary of all meetings of the stockholders, but in
the absence of the secretary at any meeting of the stockholders, the chairman of
the meeting may appoint any person to act as secretary of the meeting.

       1.14   List of Stockholders Entitled to Vote. The officer who has charge
of the stock ledger of the corporation shall prepare and make, at least ten (10)
days before every meeting of stockholders, a complete list of the stockholders
entitled to vote at the meeting, arranged in alphabetical order, and showing the
address of each stockholder and the number of shares registered in the name of
each stockholder. Such list shall be open to the examination of any stockholder,
for any purpose germane to the meeting, during ordinary business hours, for a
period of at least ten (10) days prior to the meeting, either at a place within
the city where the meeting is to be held, which place shall be specified in the
notice of the meeting, or, if not so specified, at the place where the meeting
is to be held. The list shall also be produced and kept at the time and place of
the meeting during the whole time thereof, and may be inspected by any
stockholder who is present.

       1.15   Waiver of Notice. Whenever notice is required to be given under
any provision of the General Corporation Law of Delaware or of the certificate
of incorporation or these bylaws, a written waiver thereof, signed by the person
entitled to notice, whether before or after the time stated therein, shall be
deemed equivalent to notice. Attendance of a person at a meeting shall
constitute a waiver of notice of such meeting, except when the person attends a
meeting for the express purpose of objecting, at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the stockholders need be specified in any written
waiver of notice unless so required by the certificate of incorporation or these
bylaws.


                                    ARTICLE 2

                                    DIRECTORS

       2.1    General Powers. Subject to the provisions of the General
Corporation Law of Delaware and to any limitations in the certificate of
incorporation or these bylaws relating to action required to be approved by the
stockholders or by the outstanding shares, the business and affairs of the
corporation shall be managed and all corporate powers shall be exercised by or
under the direction of the board of directors.

       2.2    Number; Election and Qualification.

              (a)    The board of directors shall consist of five (5) members.
The number of directors may be changed by an amendment to this bylaw, duly
adopted by the board of directors or by the stockholders, or by a duly adopted
amendment to the certificate of incorporation. If the number of directors is
hereafter changed, any newly created directorships or decrease in directorships
shall be so apportioned among the classes as to make all classes as nearly equal
in number as is practicable, provided that no decrease in the number of
directors constituting the board of directors shall shorten the term of any
incumbent director.

              (b)    Upon the closing of the first sale of the corporation's
common stock pursuant to a firmly underwritten registered public offering (the
"IPO"), the directors shall be divided into three classes, with the term of
office of the first class, which class shall initially consist of two directors,
to expire at the first annual meeting of stockholders held after the IPO; the
term of office of the second class, which class shall initially consist of one
director, to expire at the second annual meeting of stockholders held after the
IPO; the term of office of the third class, which class shall initially consist
of two directors, to expire at the third annual meeting of stockholders held
after the IPO; and thereafter for each such term to expire at each third
succeeding annual meeting of stockholders held after such election.

       2.3    Election and Term of Office of Directors. Except as provided in
Section 2.4 of these bylaws, directors shall be elected at each annual meeting
of stockholders to hold office as provided


                                      -6-
<PAGE>   11
in Section 2.4 of these bylaws. Each director, including a director elected or
appointed to fill a vacancy, shall hold office until the expiration of the term
for which elected and until a successor has been elected and qualified.

       2.4    Resignation and Vacancies. Any director may resign effective on
giving written notice to the chairman of the board, the president, the secretary
or the board of directors, unless the notice specifies a later time for that
resignation to become effective. If the resignation of a director is effective
at a future time, the board of directors may elect a successor to take office
when the resignation becomes effective.

              Vacancies in the board of directors may be filled by a majority of
the remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote of
the stockholders or by court order may be filled only by the affirmative vote of
a majority of the shares represented and voting at a duly held meeting at which
a quorum is present (which shares voting affirmatively also constitute a
majority of the required quorum). Each director so elected shall hold office for
a term expiring at the next annual meeting of the stockholders at which the term
of office of the class to which such director has been elected expires.

              Unless otherwise provided in the certificate of incorporation or
these bylaws:

              (i)    Vacancies and newly created directorships resulting from
any increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

              (ii)   Whenever the holders of any class or classes of stock or
series thereof are entitled to elect one or more directors by the provisions of
the certificate of incorporation, vacancies and newly created directorships of
such class or classes or series may be filled by a majority of the directors
elected by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

              If at any time, by reason of death or resignation or other cause,
the corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

              If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of
the whole board (as constituted immediately prior to any such increase), then
the Court of Chancery may, upon application of any stockholder or


                                      -7-
<PAGE>   12
stockholders holding at least ten (10) percent of the total number of the shares
at the time outstanding having the right to vote for such directors, summarily
order an election to be held to fill any such vacancies or newly created
directorships, or to replace the directors chosen by the directors then in
office as aforesaid, which election shall be governed by the provisions of
Section 211 of the General Corporation Law of Delaware as far as applicable.

       2.5    Removal of Directors. Except as otherwise provided by the General
Corporation Law of Delaware, any one or more or all of the directors may be
removed, with or without cause, by the holders of a majority of the shares then
entitled to vote at an election of directors, provided, however, that, if and so
long as stockholders of the corporation are entitled to cumulative voting, if
less than the entire board is to be removed, no director may be removed without
cause if the votes cast against his removal would be sufficient to elect him if
then cumulatively voted at an election of the entire board of directors.

       2.6    Place of Meetings; Meetings by Telephone. Regular meetings of the
board of directors may be held at any place within or outside the State of
Delaware that has been designated from time to time by resolution of the board.
In the absence of such a designation, regular meetings shall be held at the
principal executive office of the corporation. Special meetings of the board may
be held at any place within or outside the State of Delaware that has been
designated in the notice of the meeting or, if not stated in the notice or if
there is no notice, at the principal executive office of the corporation.

              Any meeting of the board, regular or special, may be held by
conference telephone or similar communication equipment, so long as all
directors participating in the meeting can hear one another; and all such
participating directors shall be deemed to be present in person at the meeting.

       2.7    First Meetings. The first meeting of each newly elected board of
directors shall be held at such time and place as shall be fixed by the vote of
the stockholders at the annual meeting. In the event of the failure of the
stockholders to fix the time or place of such first meeting of the newly elected
board of directors, or in the event such meeting is not held at the time and
place so fixed by the stockholders, the meeting may be held at such time and
place as shall be specified in a notice given as hereinafter provided for
special meetings of the board of directors, or as shall be specified in a
written waiver signed by all of the directors.

       2.8    Regular Meetings. Regular meetings of the Board of Directors may
be held without notice at such time and place, either within or without the
State of Delaware, as shall be determined from time to time by the Board of
Directors. If any regular meeting day shall fall on a legal holiday, then the
meeting shall be held at the same time and place on the next succeeding full
business day.

       2.9    Special Meetings. Special meetings of the Board of Directors for
any purpose or purposes may be called at any time by the Chairman of the Board,
President, any Vice President, the Secretary or any two directors.

constitute a quorum for the transaction of business, except to adjourn as
provided in Section 2.13 of these bylaws. Every act or decision done or made by
a majority of the directors present at a duly held meeting at which a quorum is
present shall be regarded as the act of the board of directors, subject to the
provisions of the certificate of incorporation and applicable law.

              A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of director, if any action
taken is approved by at least a majority of the quorum for that meeting.

       2.11   Waiver of Notice. Notice of a meeting need not be given to any
director (i) who signs a waiver of notice, whether before or after the meeting,
or (ii) who attends the meeting other than for the express purposed of objecting
at the beginning of the meeting to the transaction of any business because the
meeting is not lawfully called or convened. All such waivers shall be filed with
the corporate records or made part of the minutes of the meeting. A waiver of
notice need not specify the purpose of any regular or special meeting of the
board of directors.

       2.12   Adjournment. A majority of the directors present, whether or not
constituting a quorum, may adjourn any meeting of the board to another time and
place.

       2.13   Notice of Adjournment. Notice of the time and place of holding an
adjourned meeting of the board need not be given unless the meeting is adjourned
for more than twenty-four (24) hours. If the meeting is adjourned for more than

meeting shall be given before the adjourned meeting takes place, in the manner

at the time of the adjournment.

       2.14   Board Action by Written Consent Without a Meeting. Any action
required or permitted to be taken at any meeting of the Board of Directors or of
any committee of the Board of Directors may be taken without a meeting, if all

       2.15   Fees and Compensation of Directors. Directors and members of
committees may receive such compensation, if any, for their services and such
reimbursement of expenses as may be fixed or determined by resolution of the
board of directors. This Section 2.16 shall not be construed to preclude any
director from serving the corporation in any other capacity as an officer,
agent, employee or otherwise and receiving compensation for those services.

                                    ARTICLE 3

pleasure of the board. The board may designate one (1) or more directors as
alternate members of any committee, who may replace any absent or disqualified
member at any meeting of the committee. The appointment of members or alternate
members of a committee requires the vote of a majority of the authorized number
of directors. Any committee, to the extent provided in the resolution of the
board, shall have and may exercise all the powers and authority of the board,
but no such committee shall have the power or authority to (i) amend the

no such committee shall have the power or authority to declare a dividend, to
authorize the issuance of stock, or to adopt a certificate of ownership and
merger pursuant to Section 253 of the General Corporation Law of Delaware.

       3.2    Meetings and Action of Committees. Meetings and actions of

directors or by resolution of the committee, that special meetings of committees
may also be called by resolution of the board of directors, and that notice of

              Any Officer may resign at any time by giving written notice to the
corporation. Any resignation shall take effect at the date of the receipt of
that notice or at any later time specified in that notice; and, unless otherwise

                INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES
                                AND OTHER AGENTS

       5.1    Indemnification of Directors and Officers. The corporation shall,
to the maximum extent and in the manner permitted by the General Corporation Law
of Delaware as the same now exists or may hereafter be amended, indemnify any
person against expenses (including attorneys' fees), judgments, fines, and
amounts paid in settlement actually and reasonably incurred in connection with
any threatened, pending or completed action, suit, or proceeding in which such
person was or is a party or is threatened to be made a party by reason of the
fact that such person is or was a director or officer of the corporation. For
purposes of this Section 5.1, a "director" or "officer" of the corporation shall
mean any person (i) who is or was a director or officer of the corporation, (ii)
who is or was serving at the request of the corporation as a director or officer
of another corporation, partnership, joint venture, trust or other enterprise,
or (iii) who was a director or officer of a corporation which was a predecessor
corporation of the corporation or of another enterprise at the request of such
predecessor corporation.

              The corporation shall be required to indemnify a director or
officer in connection with an action, suit, or proceeding (or part thereof)
initiated by such director or officer only if the initiation of such action,
suit, or proceeding (or part thereof) by the director or officer was authorized
by the Board of Directors of the corporation.

              The corporation shall pay the expenses (including attorney's fees)
incurred by a director or officer of the corporation entitled to indemnification
hereunder in defending any action, suit or proceeding referred to in this
Section 5.1 in advance of its final disposition; provided, however, that payment
of expenses incurred by a director or officer of the corporation in advance of
the final disposition of such action, suit or proceeding shall be made only upon
receipt of an undertaking by the director or officer to repay all amounts
advanced if it should ultimately be determined that the director of officer is
not entitled to be indemnified under this Section 5.1 or otherwise.

              The rights conferred on any person by this Article shall not be
exclusive of any other rights which such person may have or hereafter acquire
under any statute, provision of the


                                      -14-
<PAGE>   19
corporation's Certificate of Incorporation, these bylaws, agreement, vote of the
stockholders or disinterested directors or otherwise.

              Any repeal or modification of the foregoing provisions of this
Article shall not adversely affect any right or protection hereunder of any
person in respect of any act or omission occurring prior to the time of such
repeal or modification.

       5.2    Indemnification of Others. The corporation shall have the power,
to the maximum extent and in the manner permitted by the General Corporation Law
of Delaware as the same now exists or may hereafter be amended, to indemnify any
person (other than directors and officers) against expenses (including
attorneys' fees), judgments, fines, and amounts paid in settlement actually and
reasonably incurred in connection with any threatened, pending or completed
action, suit, or proceeding, in which such person was or is a party or is
threatened to be made a party by reason of the fact that such person is or was
an employee or agent of the corporation. For purposes of this Section 5.2, an
"employee" or "agent" of the corporation (other than a director or officer)
shall mean any person (i) who is or was an employee or agent of the corporation,
(ii) who is or was serving at the request of the corporation as an employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, or (iii) who was an employee or agent of a corporation which was a
predecessor corporation of the corporation or of another enterprise at the
request of such predecessor corporation.

       5.3    Insurance. The corporation may purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him or
her and incurred by him or her in any such capacity, or arising out of his or
her status as such, whether or not the corporation would have the power to
indemnify him or her against such liability under the provisions of the General
Corporation Law of Delaware.


                                    ARTICLE 6

                               RECORDS AND REPORTS

       6.1    Maintenance and Inspection of Records. The corporation shall,
either at its principal executive office or at such place or places as
designated by the board of directors, keep a record of its stockholders listing
their names and addresses and the number and class of shares held by each
stockholder, a copy of these bylaws as amended to date, accounting books and
other records of its business and properties.

              Any stockholder of record, in person or by attorney or other
agent, shall, upon written demand under oath stating the purpose thereof, have
the right during the usual hours for business to inspect for any proper purpose
the corporation's stock ledger, a list of its stockholders, and its other


                                      -15-
<PAGE>   20
books and records and to make copies or extracts therefrom. A proper purpose
shall mean a purpose reasonably related to such person's interest as a
stockholder. In every instance where an attorney or other agent is the person
who seeks the right to inspection, the demand under oath shall be accompanied by
a power of attorney or such other writing that authorizes the attorney or other
agent to so act on behalf of the stockholder. The demand under oath shall be
directed to the corporation at its registered office in Delaware or at its
principal place of business.

       6.2    Inspection by Directors. Any director shall have the right to
examine (and to make copies of) the corporation's stock ledger, a list of its
stockholders and its other books and records for a purpose reasonably related to
his or her position as a director.

       6.3    Annual Statement to Stockholders. The board of directors shall
present at each annual meeting, and at any special meeting of the stockholders
when called for by vote of the stockholders, a full and clear statement of the
business and condition of the corporation.

       6.4    Representation of Shares of Other Corporations. The chairman of
the board, if any, the president, any vice president, the chief financial
officer, the secretary or any assistant secretary of this corporation, or any
other person authorized by the board of directors or the president or a vice
president, is authorized to vote, represent and exercise on behalf of this
corporation all rights incident to any and all shares of the stock of any other
corporation or corporations standing in the name of this corporation. The
authority herein granted may be exercised either by such person directly or by
any other person authorized to do so by proxy or power of attorney duly executed
by such person having the authority.

       6.5    Certification and Inspection of Bylaws. The original or a copy of
these bylaws, as amended or otherwise altered to date, certified by the
secretary, shall be kept at the corporation's principal executive office and
shall be open to inspection by the stockholders of the corporation, at all
reasonable times during office hours.


                                    ARTICLE 7

                                 GENERAL MATTERS

       7.1    Record Date for Purposes Other than Notice and Voting. For
purposes of determining the stockholders entitled to receive payment of any
dividend or other distribution or allotment of any rights or the stockholders
entitled to exercise any rights in respect of any change, conversion or exchange
of stock, or for the purpose of any other lawful action, the board of directors
may fix, in advance, a record date, which shall not precede the date upon which
the resolution fixing the record date is adopted and which shall not be more
than sixty (60) days before any such action. In that case, only stockholders of
record at the close of business on the date so fixed are entitled to receive the
dividend, distribution or allotment of rights, or to exercise such rights, as
the case may be, notwith-


                                      -16-
<PAGE>   21
standing any transfer of any shares on the books of the corporation after the
record date so fixed, except as otherwise provided by law.

              If the board of directors does not so fix a record date, then the
record date for determining stockholders for any such purpose shall be at the
close of business on the day on which the board of directors adopts the
applicable resolution.

       7.2    Checks; Drafts; Evidences of Indebtedness. From time to time, the
board of directors shall determine by resolution which person or persons may
sign or endorse all checks, drafts, other orders for payment of money, notes or
other evidences of indebtedness that are issued in the name of or payable to the
corporation, and only the persons so authorized shall sign or endorse those
instruments.

       7.3    Corporate Contracts and Instruments; How Executed. The board of
directors, except as otherwise provided in these bylaws, may authorize and
empower any officer or officers, or agent or agents, to enter into any contract
or execute any instrument in the name of and on behalf of the corporation; such
power and authority may be general or confined to specific instances. Unless so
authorized or ratified by the board of directors or within the agency power of
an officer, no officer, agent or employee shall have any power or authority to
bind the corporation by any contract or engagement or to pledge its credit or to
render it liable for any purpose or for any amount.

       7.4    Stock Certificates; Transfer; Partly Paid Shares. The shares of
the corporation shall be represented by certificates, provided that the board of
directors of the corporation may provide by resolution or resolutions that some
or all of any or all classes or series of its stock shall be uncertificated
shares. Any such resolution shall not apply to shares represented by a
certificate until such certificate is surrendered to the corporation.
Notwithstanding the adoption of such a resolution by the board of directors,
every holder of stock represented by certificates and, upon request, every
holder of uncertificated shares, shall be entitled to have a certificate signed
by, or in the name of the corporation by, the chairman or vice-chairman of the
board of directors, or the president or vice-president, and by the treasurer or
an assistant treasurer, or the secretary or an assistant secretary of such
corporation representing the number of shares registered in certificate form.
Any or all of the signatures on the certificate may be a facsimile. In case any
officer, transfer agent or registrar who has signed or whose facsimile signature
has been placed upon a certificate has ceased to be such officer, transfer agent
or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if he or she were such officer, transfer
agent or registrar at the date of issue.

              Certificates for shares shall be of such form and device as the
board of directors may designate and shall state the name of the record holder
of the shares represented thereby; its number; date of issuance; the number of
shares for which it is issued; a summary statement or reference to the powers,
designations, preferences or other special rights of such stock and the
qualifications, limitations or restrictions of such preferences and/or rights,
if any; a statement or summary of liens, if any; a conspicuous notice of
restrictions upon transfer or registration of transfer, if any; a


                                      -17-
<PAGE>   22
statement as to any applicable voting trust agreement; if the shares be
assessable, or, if assessments are collectible by personal action, a plain
statement of such facts.

              Upon surrender to the secretary or transfer agent of the
corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignment or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books.

              The corporation may issue the whole or any part of its shares as
partly paid and subject to call for the remainder of the consideration to be
paid therefor. Upon the face or back of each stock certificate issued to
represent any such partly paid shares, or upon the books and records of the
corporation in the case of uncertificated partly paid shares, the total amount
of the con sideration to be paid therefor and the amount paid thereon shall be
stated. Upon the declaration of any dividend on fully paid shares, the
corporation shall declare a dividend upon partly paid shares of the same class,
but only upon the basis of the percentage of the consideration actually paid
thereon.

       7.5    Special Designation on Certificates. If the corporation is
authorized to issue more than one class of stock or more than one series of any
class, then the powers, the designations, the preferences and the relative,
participating, optional or other special rights of each class of stock or series
thereof and the qualifications, limitations or restrictions of such preferences
and/or rights shall be set forth in full or summarized on the face or back of
the certificate that the corporation shall issue to represent such class or
series of stock; provided, however, that, except as otherwise provided in
Section 202 of the General Corporation Law of Delaware, in lieu of the foregoing
requirements there may be set forth on the face or back of the certificate that
the corporation shall issue to represent such class or series of stock a
statement that the corporation will furnish without charge to each stockholder
who so requests the powers, the designations, the preferences and the relative,
participating, optional or other special rights of each class of stock or series
thereof and the qualifications, limitations or restrictions of such preferences
and/or rights.

       7.6    Lost certificates. Except as provided in this Section 7.6, no new
certificates for shares shall be issued to replace a previously issued
certificate unless the latter is surrendered to the corporation and canceled at
the same time. The board of directors may, in case any share certificate or
certificate for any other security is lost, stolen or destroyed, authorize the
issuance of replacement certificates on such terms and conditions as the board
may require; the board may require indemnification of the corporation secured by
a bond or other adequate security sufficient to protect the corporation against
any claim that may be made against it, including any expense or liability, on
account of the alleged loss, theft or destruction of the certificate or the
issuance of the replacement certificate.

       7.7    Transfer Agents and Registrars. The board of directors may appoint
one or more transfer agents or transfer clerks, and one or more registrars, each
of which shall be an incorporated bank or trust company -- either domestic or
foreign, who shall be appointed at such times and places as the requirements of
the corporation may necessitate and the board of directors may designate.

       7.8    Construction; Definitions. Unless the context requires otherwise,
the general provisions, rules of construction and definitions in the General
Corporation Law of Delaware shall govern the construction of these bylaws.
Without limiting the generality of this provision, as used in these bylaws, the
singular number includes the plural, the plural number includes the singular,
and the term "person" includes both an entity and a natural person.


                                    ARTICLE 8

                                   AMENDMENTS

       The original or other bylaws of the corporation may be adopted, amended
or repealed by the stockholders entitled to vote or by the board of directors of
the corporation. The fact that such power has been so conferred upon the
directors shall not divest the stockholders of the power, nor limit their power
to adopt, amend or repeal bylaws.

       Whenever an amendment or new bylaw is adopted, it shall be copied in the
book of bylaws with the original bylaws, in the appropriate place. If any bylaw
is repealed, the fact of repeal with the date of the meeting at which the repeal
was enacted or the filing of the operative written consent(s) shall be stated in
said book.

                   (iv)   Other Administration. Other than as provided above,

committee shall be constituted to satisfy Applicable Laws.

             (b) Powers of the Administrator. Subject to the provisions of the
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

                   (i)    to determine the Fair Market Value;

                   (ii)   to select the Service Providers to whom Options and
Stock Purchase Rights may be granted hereunder;

                   (iii)  to determine the number of shares of Common Stock to
be covered by each Option and Stock Purchase Right granted hereunder;

                   (iv)   to approve forms of agreement for use under the Plan;

                   (v)    to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any Option or Stock Purchase Right
granted hereunder. Such terms and conditions include, but are not limited to,
the exercise price, the time or times when Options or Stock Purchase Rights may
be exercised (which may be based on performance criteria), any vesting
acceleration or waiver of forfeiture restrictions, and any restriction or
limitation regarding any Option or Stock Purchase Right or the shares of Common
Stock relating thereto, based in each case on such factors as the Administrator,
in its sole discretion, shall determine;

                   (vi)   to reduce the exercise price of any Option or Stock
Purchase Right to the then current Fair Market Value if the Fair Market Value of
the Common Stock covered by such Option or Stock Purchase Right shall have
declined since the date the Option or Stock Purchase Right was granted;

                   (vii)  to institute an Option Exchange Program;

                   (viii) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan;

                   (ix)   to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;



                                       -5-


<PAGE>   6


                   (x)    to modify or amend each Option or Stock Purchase Right
(subject to Section 15(c) of the Plan), including the discretionary authority to
extend the post-termination exercisability period of Options longer than is
otherwise provided for in the Plan;

                   (xi)   to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option or Stock Purchase Right that number of Shares
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined. All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable;

                   (xii)  to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Option or Stock
Purchase Right previously granted by the Administrator;

                   (xiii) to make all other determinations deemed necessary or
advisable for administering the Plan.

             (c) Effect of Administrator's Decision. The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options or Stock Purchase Rights.

       5.    Eligibility. Nonstatutory Stock Options and Stock Purchase Rights
may be granted to Service Providers. Incentive Stock Options may be granted only
to Employees.

       6.    Limitations.

             (a) Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

             (b) Neither the Plan nor any Option or Stock Purchase Right shall
confer upon an Optionee any right with respect to continuing the Optionee's
relationship as a Service Provider with the Company, nor shall they interfere in
any way with the Optionee's right or the Company's right to terminate such
relationship at any time, with or without cause.



                                       -6-


<PAGE>   7



             (c) The following limitations shall apply to grants of Options:

                   (i) No Service Provider shall be granted, in any fiscal year
of the Company, Options to purchase more than 300,000 Shares.

                   (ii) In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 300,000 Shares
which shall not count against the limit set forth in subsection (i) above.

                   (iii) The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 13.

                   (iv) If an Option is cancelled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 13), the cancelled Option will be counted against the
limits set forth in subsections (i) and (ii) above. For this purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option.

       7.    Term of Plan. Subject to Section 19 of the Plan, the Plan shall
become effective upon its adoption by the Board. It shall continue in effect for
a term of ten (10) years unless terminated earlier under Section 15 of the Plan.

       8.    Term of Option. The term of each Option shall be stated in the
Option Agreement. In the case of an Incentive Stock Option, the term shall be
ten (10) years from the date of grant or such shorter term as may be provided in
the Option Agreement. Moreover, in the case of an Incentive Stock Option granted
to an Optionee who, at the time the Incentive Stock Option is granted, owns
stock representing more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
term of the Incentive Stock Option shall be five (5) years from the date of
grant or such shorter term as may be provided in the Option Agreement.

       9.    Option Exercise Price and Consideration.

             (a) Exercise Price. The per share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

                   (i)   In the case of an Incentive Stock Option

                         (A) granted to an Employee who, at the time the
Incentive Stock Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant.



                                       -7-
<PAGE>   8



                         (B) granted to any Employee other than an Employee
described in paragraph (A) immediately above, the per Share exercise price shall
be no less than 100% of the Fair Market Value per Share on the date of grant.

                   (ii) In the case of a Nonstatutory Stock Option, the per
Share exercise price shall be determined by the Administrator. In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                   (iii) Notwithstanding the foregoing, Options may be granted
with a per Share exercise price of less than 100% of the Fair Market Value per
Share on the date of grant pursuant to a merger or other corporate transaction.

             (b) Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.

             (c) Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant. Such
consideration may consist entirely of:

                   (i)   cash;

                   (ii)  check;

                   (iii) promissory note;

                   (iv) other Shares which (A) in the case of Shares acquired
upon exercise of an option, have been owned by the Optionee for more than six
months on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

                   (v) consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan;

                   (vi) a reduction in the amount of any Company liability to
the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;

                   (vii) any combination of the foregoing methods of payment; or



                                       -8-


<PAGE>   9



                   (viii) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.

             10. Exercise of Option.

             (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence. An Option may not be exercised for a fraction of a Share.

                 An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 13 of the Plan.

                 Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

             (b) Termination of Relationship as a Service Provider. If an
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.



                                       -9-


<PAGE>   10



             (c) Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
to the extent the Option is vested on the date of termination (but in no event
later than the expiration of the term of such Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall revert to the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

             (d) Death of Optionee. If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person who acquires the right to exercise the Option by bequest or
inheritance, but only to the extent that the Option is vested on the date of
death. In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan. The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the person(s)
entitled to exercise the Option under the Optionee's will or the laws of descent
or distribution. If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

             (e) Buyout Provisions. The Administrator may at any time offer to
buy out for a payment in cash or Shares an Option previously granted based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

       11.   Stock Purchase Rights.

             (a) Rights to Purchase. Stock Purchase Rights may be issued either
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically, by means of a Notice of Grant, of the
terms, conditions and restrictions related to the offer, including the number of
Shares that the offeree shall be entitled to purchase, the price to be paid, and
the time within which the offeree must accept such offer. The offer shall be
accepted by execution of a Restricted Stock Purchase Agreement in the form
determined by the Administrator.

             (b) Repurchase Option. Unless the Administrator determines
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's service with the Company for any reason



                                      -10-


<PAGE>   11



(including death or Disability). The purchase price for Shares repurchased
pursuant to the Restricted Stock Purchase Agreement shall be the original price
paid by the purchaser and may be paid by cancellation of any indebtedness of the
purchaser to the Company. The repurchase option shall lapse at a rate determined
by the Administrator.

             (c) Other Provisions. The Restricted Stock Purchase Agreement shall
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

             (d) Rights as a Shareholder. Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 13
of the Plan.

             12. Non-Transferability of Options and Stock Purchase Rights.
Unless determined otherwise by the Administrator, an Option or Stock Purchase
Right may not be sold, pledged, assigned, hypothecated, transferred, or disposed
of in any manner other than by will or by the laws of descent or distribution
and may be exercised, during the lifetime of the Optionee, only by the Optionee.
If the Administrator makes an Option or Stock Purchase Right transferable, such
Option or Stock Purchase Right shall contain such additional terms and
conditions as the Administrator deems appropriate.

             13. Adjustments Upon Changes in Capitalization, Dissolution, Merger
or Asset Sale.

             (a) Changes in Capitalization. Subject to any required action by
the shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option and Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option or Stock
Purchase Right.



                                      -11-


<PAGE>   12



             (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option or Stock Purchase Right shall lapse
as to all such Shares, provided the proposed dissolution or liquidation takes
place at the time and in the manner contemplated. To the extent it has not been
previously exercised, an Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

             (c) Merger or Asset Sale. In the event of a merger of the Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Stock Purchase Right shall be
assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation. In the event
that the successor corporation refuses to assume or substitute for the Option or
Stock Purchase Right, the Optionee shall fully vest in and have the right to
exercise the Option or Stock Purchase Right as to all of the Optioned Stock,
including Shares as to which it would not otherwise be vested or exercisable. If
an Option or Stock Purchase Right becomes fully vested and exercisable in lieu
of assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option or Stock Purchase Right shall be fully vested and exercisable for a
period of fifteen (15) days from the date of such notice, and the Option or
Stock Purchase Right shall terminate upon the expiration of such period. For the
purposes of this paragraph, the Option or Stock Purchase Right shall be
considered assumed if, following the merger or sale of assets, the option or
right confers the right to purchase or receive, for each Share of Optioned Stock
subject to the Option or Stock Purchase Right immediately prior to the merger or
sale of assets, the consideration (whether stock, cash, or other securities or
property) received in the merger or sale of assets by holders of Common Stock
for each Share held on the effective date of the transaction (and if holders
were offered a choice of consideration, the type of consideration chosen by the
holders of a majority of the outstanding Shares); provided, however, that if
such consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option or Stock Purchase Right, for each Share
of Optioned Stock subject to the Option or Stock Purchase Right, to be solely
common stock of the successor corporation or its Parent equal in fair market
value to the per share consideration received by holders of Common Stock in the
merger or sale of assets.

             14. Date of Grant. The date of grant of an Option or Stock Purchase
Right shall be, for all purposes, the date on which the Administrator makes the
determinatioen granting such Option or Stock Purchase Right, or such other later
date as is determined by the Administrator. Notice of the



                                      -12-


<PAGE>   13



determination shall be provided to each Optionee within a reasonable time after
the date of such grant.

             15. Amendment and Termination of the Plan.

             (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or terminate the Plan.

             (b) Shareholder Approval. The Company shall obtain shareholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

             (c) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

             16. Conditions Upon Issuance of Shares.

             (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option or Stock Purchase Right unless the exercise of such Option
or Stock Purchase Right and the issuance and delivery of such Shares shall
comply with Applicable Laws and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

             (b) Investment Representations. As a condition to the exercise of
an Option or Stock Purchase Right, the Company may require the person exercising
such Option or Stock Purchase Right to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required.

             17. Inability to Obtain Authority. The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

             18. Reservation of Shares. The Company, during the term of this
Plan, will at all times reserve and keep available such number of Shares as
shall be sufficient to satisfy the requirements of the Plan.

       19. Shareholder Approval. The Plan shall be subject to approval by the
shareholders of the Company within twelve (12) months after the date the Plan is
adopted. Such shareholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

following schedule:

       25% of the Shares subject to the Option shall vest twelve months after

<PAGE>   16



       Termination Period:

       This Option may be exercised for 30 days after Optionee ceases to be a
Service Provider. Upon the death or Disability of the Optionee, this Option may
be exercised for one year after Optionee ceases to be a Service Provider. In no

II.  AGREEMENT

       1.    Grant of Option. The Plan Administrator of the Company hereby
grants to the Optionee named in the Notice of Grant attached as Part I of this
Agreement (the "Optionee") an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the "Exercise Price"), subject to the terms and
conditions of the Plan, which is incorporated herein by reference. Subject to
Section 15(c) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of this Option Agreement,
the terms and conditions of the Plan shall prevail.

             If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code. However, if this Option is intended to be an Incentive
Stock Option, to the extent that it exceeds the $100,000 rule of Code Section
422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

       2.    Exercise of Option.

             (a) Right to Exercise. This Option is exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

             (b) Method of Exercise. This Option is exercisable by delivery of
an exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed
by the Optionee and delivered to the Chief Financial Officer of the Company. The
Exercise Notice shall be accompanied by payment of the aggregate Exercise Price
as to all Exercised Shares. This Option shall be deemed to be exercised upon
receipt by the Company of such fully executed Exercise Notice accompanied by
such aggregate Exercise Price.

             No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

<PAGE>   17



       3.    Method of Payment. Payment of the aggregate Exercise Price shall be
by any of the following, or a combination thereof, at the election of the
Optionee:

             (a)   cash; or

             (b)   check; or

             (c) consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan; or

             (d) surrender of other Shares which (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, AND (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares; or

             (e) with the Administrator's consent, delivery of Optionee's
promissory note (the "Note") in the form attached hereto as Exhibit C, in the
amount of the aggregate Exercise Price of the Exercised Shares together with the
execution and delivery by the Optionee of the Security Agreement attached hereto
as Exhibit B. The Note shall bear interest at the "applicable federal rate"
prescribed under the Code and its regulations at time of purchase, and shall be
secured by a pledge of the Shares purchased by the Note pursuant to the Security
Agreement.

       4.    Non-Transferability of Option. This Option may not be transferred
in any manner otherwise than by will or by the laws of descent or distribution
and may be exercised during the lifetime of Optionee only by the Optionee. The
terms of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

       5.    Term of Option. This Option may be exercised only within the term
set out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.

       6.    Tax Consequences. Some of the federal tax consequences relating to
this Option, as of the date of this Option, are set forth below. THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR
DISPOSING OF THE SHARES.

             (a)   Exercising the Option.

                   (i) Nonstatutory Stock Option. The Optionee may incur regular
federal income tax liability upon exercise of a NSO. The Optionee will be
treated as having received compensation income (taxable at ordinary income tax
rates) equal to the excess, if any, of the Fair



                                       -3-


<PAGE>   18



Market Value of the Exercised Shares on the date of exercise over their
aggregate Exercise Price. If the Optionee is an Employee or a former Employee,
the Company will be required to withhold from his or her compensation or collect
from Optionee and pay to the applicable taxing authorities an amount in cash
equal to a percentage of this compensation income at the time of exercise, and
may refuse to honor the exercise and refuse to deliver Shares if such
withholding amounts are not delivered at the time of exercise.

                   (ii) Incentive Stock Option. If this Option qualifies as an
ISO, the Optionee will have no regular federal income tax liability upon its
exercise, although the excess, if any, of the Fair Market Value of the Exercised
Shares on the date of exercise over their aggregate Exercise Price will be
treated as an adjustment to alternative minimum taxable income for federal tax
purposes and may subject the Optionee to alternative minimum tax in the year of
exercise. In the event that the Optionee ceases to be an Employee but remains a
Service Provider, any Incentive Stock Option of the Optionee that remains
unexercised shall cease to qualify as an Incentive Stock Option and will be
treated for tax purposes as a Nonstatutory Stock Option on the date three (3)
months and one (1) day following such change of status.

             (b) Disposition of Shares.

                   (i) NSO. If the Optionee holds NSO Shares for at least one
year, any gain realized on disposition of the Shares will be treated as
long-term capital gain for federal income tax purposes.

                   (ii) ISO. If the Optionee holds ISO Shares for at least one
year after exercise and two years after the grant date, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes. If the Optionee disposes of ISO Shares within one year
after exercise or two years after the grant date, any gain realized on such
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the excess, if any, of the lesser of (A) the difference
between the Fair Market Value of the Shares acquired on the date of exercise and
the aggregate Exercise Price, or (B) the difference between the sale price of
such Shares and the aggregate Exercise Price. Any additional gain will be taxed
as capital gain, short-term or long-term depending on the period that the ISO
Shares were held.

             (c) Notice of Disqualifying Disposition of ISO Shares. If the
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
an ISO on or before the later of (i) two years after the grant date, or (ii) one
year after the exercise date, the Optionee shall immediately notify the Company
in writing of such disposition. The Optionee agrees that he or she may be
subject to income tax withholding by the Company on the compensation income
recognized from such early disposition of ISO Shares by payment in cash or out
of the current earnings paid to the Optionee.

THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES

NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A

of the Code.

the Company is at least thirty (30) hours per week. For purposes of the Plan,
the employment relationship shall be treated as continuing intact while the

Where the period of leave exceeds 90 days and the individual's right to
reemployment is not guaranteed either by statute or by contract, the employment
relationship shall be deemed to have terminated on the 91st day of such leave.

               (h) "Enrollment Date" shall mean the first day of each Offering
Period.

the last market trading day on the date of such determination, as reported in
The Wall Street Journal or such other source as the Administrator deems
reliable, or;

                      (2) If the Common Stock is regularly quoted by a
recognized securities dealer but selling prices are not reported, its Fair
Market Value shall be the mean of the closing bid and asked prices for the
Common Stock on the date of such determination, as reported in The Wall Street
Journal or such other source as the Board deems reliable, or;

                      (3) In the absence of an established market for the Common
Stock, the Fair Market Value thereof shall be determined in good faith by the
Board, or;

                      (4) For purposes of the Enrollment Date of the first
Offering Period under the Plan, the Fair Market Value shall be the initial
price to the public as set forth in the final prospectus included within the

Enrollment Date shall be eligible to participate in the Plan.

               (b) Any provisions of the Plan to the contrary notwithstanding,
no Employee shall be granted an option under the Plan (i) to the extent that,
immediately after the grant, such Employee (or any other person whose stock
would be attributed to such Employee pursuant to Section 424(d) of the Code)
would own capital stock of the Company and/or hold outstanding options to
purchase such stock possessing five percent (5%) or more of the total combined
voting power or value of all classes of the capital stock of the Company or of
any Subsidiary, or (ii) to the extent that his or her rights to purchase stock
under all employee stock purchase plans of the Company and its subsidiaries
accrues at a rate which exceeds Twenty-Five Thousand Dollars ($25,000) worth of
stock (determined at the fair market value of the shares at the time such option
is granted) for each calendar year in which such option is outstanding at any
time.

        4.     Offering Periods. The Plan shall be implemented by consecutive,
overlapping Offering Periods with a new Offering Period commencing on the first
Trading Day on or after January 1 and July 1 of each year, or on such other date
as the Board shall determine, and continuing thereafter until terminated in
accordance with Section 20 hereof; provided, however, that the first Offering
Period under the Plan shall commence with the first Trading Day on or after the
date on which the Securities and Exchange Commission declares the Company's
Registration Statement effective and ending on the last Trading Day on or before

Offering Periods (including the commencement dates thereof) with respect to
future offerings without shareholder approval if such change is announced at
least five (5) days prior to the scheduled beginning of the first Offering
Period to be affected thereafter.

        5.     Participation.

               (a) An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office prior
to the applicable Enrollment Date.

               (b) Payroll deductions for a participant shall commence on the
first payroll following the Enrollment Date and shall end on the last payroll in
the Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.



                                       -3-
<PAGE>   4



        6.     Payroll Deductions.

               (a) At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding 15% of the Compensation
which he or she receives on each pay day during the Offering Period.

               (b) All payroll deductions made for a participant shall be
credited to his or her account under the Plan and shall be withheld in whole
percentages only. A participant may not make any additional payments into such
account.

               (c) A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions during the Offering Period by completing or filing
with the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

               (d) Notwithstanding the foregoing, to the extent necessary to
comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a
participant's payroll deductions may be decreased to zero percent (0%) at any
time during a Purchase Period. Payroll deductions shall recommence at the rate
provided in such participant's subscription agreement at the beginning of the
first Purchase Period which is scheduled to end in the following calendar year,
unless terminated by the participant as provided in Section 10 hereof.

               (e) At the time the option is exercised, in whole or in part, or
at the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

        7.     Grant of Option. On the Enrollment Date of each Offering Period,
each eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to



                                       -4-

<PAGE>   5



purchase during each Purchase Period more than 30,000 shares of the Company's
Common Stock (subject to any adjustment pursuant to Section 19), and provided
further that such purchase shall be subject to the limitations set forth in
Sections 3(b) and 12 hereof. Exercise of the option shall occur as provided in
Section 8 hereof, unless the participant has withdrawn pursuant to Section 10
hereof. The option shall expire on the last day of the Offering Period.

        8.     Exercise of Option. Unless a participant withdraws from the Plan
as provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

        9.     Delivery. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

        10.    Withdrawal.

               (a) A participant may withdraw all but not less than all the
payroll deductions credited to his or her account and not yet used to exercise
his or her option under the Plan at any time by giving written notice to the
Company in the form of Exhibit B to this Plan. All of the participant's payroll
deductions credited to his or her account shall be paid to such participant
promptly after receipt of notice of withdrawal and such participant's option for
the Offering Period shall be automatically terminated, and no further payroll
deductions for the purchase of shares shall be made for such Offering Period. If
a participant withdraws from an Offering Period, payroll deductions shall not
resume at the beginning of the succeeding Offering Period unless the participant
delivers to the Company a new subscription agreement.

               (b) A participant's withdrawal from an Offering Period shall not
have any effect upon his or her eligibility to participate in any similar plan
which may hereafter be adopted by the Company or in succeeding Offering Periods
which commence after the termination of the Offering Period from which the
participant withdraws.

        11.    Termination of Employment.

               Upon a participant's ceasing to be an Employee, for any reason,
he or she shall be deemed to have elected to withdraw from the Plan and the
payroll deductions credited to such



                                       -5-
<PAGE>   6

participant's account during the Offering Period but not yet used to exercise
the option shall be returned to such participant or, in the case of his or her
death, to the person or persons entitled thereto under Section 15 hereof, and
such participant's option shall be automatically terminated. The preceding
sentence notwithstanding, a participant who receives payment in lieu of notice
of termination of employment shall be treated as continuing to be an Employee
for the participant's customary number of hours per week of employment during
the period in which the participant is subject to such payment in lieu of
notice.

        12.    Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

        13.    Stock.

               (a) Subject to adjustment upon changes in capitalization of the
Company as provided in Section 19 hereof, the maximum number of shares of the
Company's Common Stock which shall be made available for sale under the Plan
shall be 300,000 shares. If, on a given Exercise Date, the number of shares with
respect to which options are to be exercised exceeds the number of shares then
available under the Plan, the Company shall make a pro rata allocation of the
shares remaining available for purchase in as uniform a manner as shall be
practicable and as it shall deter mine to be equitable.

               (b) The participant shall have no interest or voting right in
shares covered by his option until such option has been exercised.

               (c) Shares to be delivered to a participant under the Plan shall
be registered in the name of the participant or in the name of the participant
and his or her spouse.

        14.    Administration. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

        15.    Designation of Beneficiary.

               (a) A participant may file a written designation of a beneficiary
who is to receive any shares and cash, if any, from the participant's account
under the Plan in the event of such participant's death subsequent to an
Exercise Date on which the option is exercised but prior to delivery to such
participant of such shares and cash. In addition, a participant may file a
written designation of a beneficiary who is to receive any cash from the
participant's account under the Plan in the event of such participant's death
prior to exercise of the option. If a participant is married and the designated
beneficiary is not the spouse, spousal consent shall be required for such
designation to be effective.



                                       -6-
<PAGE>   7



               (b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

        16.    Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

        17.    Use of Funds. All payroll deductions received or held by the
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such payroll deductions.

        18.    Reports. Individual accounts shall be maintained for each
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

        19.    Adjustments Upon Changes in Capitalization, Dissolution,
               Liquidation, Merger or Asset Sale.

               (a) Changes in Capitalization. Subject to any required action by
the shareholders of the Company, the Reserves, the maximum number of shares each
participant may purchase each Purchase Period (pursuant to Section 7), as well
as the price per share and the number of shares of Common Stock covered by each
option under the Plan which has not yet been exercised shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration". Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an option.



                                       -7-
<PAGE>   8



               (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The New
Exercise Date shall be before the date of the Company's proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

               (c) Merger or Asset Sale. In the event of a proposed sale of all
or substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the option, any Purchase Periods
then in progress shall be shortened by setting a new Exercise Date (the "New
Exercise Date") and any Offering Periods then in progress shall end on the New
Exercise Date. The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

        20.    Amendment or Termination.

               (a) The Board of Directors of the Company may at any time and for
any reason terminate or amend the Plan. Except as provided in Section 19 hereof,
no such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Plan is in the best
interests of the Company and its shareholders. Except as provided in Section 19
hereof, no amendment may make any change in any option theretofore granted which
adversely affects the rights of any participant. To the extent necessary to
comply with Section 423 of the Code (or any successor rule or provision or any
other applicable law, regulation or stock exchange rule), the Company shall
obtain shareholder approval in such a manner and to such a degree as required.

               (b) Without shareholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or



                                       -8-
<PAGE>   9



accounting and crediting procedures to ensure that amounts applied toward the
purchase of Common Stock for each participant properly correspond with amounts
withheld from the participant's Compensation, and establish such other
limitations or procedures as the Board (or its committee) determines in its sole
discretion advisable which are consistent with the Plan.

        21.    Notices. All notices or other communications by a participant to
the Company under or in connection with the Plan shall be deemed to have been
duly given when received in the form specified by the Company at the location,
or by the person, designated by the Company for the receipt thereof.

        22.    Conditions Upon Issuance of Shares. Shares shall not be issued
with respect to an option unless the exercise of such option and the issuance
and delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

               As a condition to the exercise of an option, the Company may
require the person exercising such option to represent and warrant at the time
of any such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

        23.    Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 20 hereof.

        24.    Automatic Transfer to Low Price Offering Period. To the extent
permitted by any applicable laws, regulations, or stock exchange rules if the
Fair Market Value of the Common Stock on any Exercise Date in an Offering Period
is lower than the Fair Market Value of the Common Stock on the Enrollment Date
of such Offering Period, then all participants in such Offering Period shall be
automatically withdrawn from such Offering Period immediately after the exercise
of their option on such Exercise Date and automatically re-enrolled in the
immediately following Offering Period as of the first day thereof.

                             SUBSCRIPTION AGREEMENT


_____ Original Application                          Enrollment Date: ___________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)


1.      _____________________________hereby elects to participate in the
        UroSurge, Inc. 1998 Employee Stock Purchase Plan (the "Employee Stock
        Purchase Plan") and subscribes to pur chase shares of the Company's
        Common Stock in accordance with this Subscription Agreement and the
        Employee Stock Purchase Plan.

2.      I hereby authorize payroll deductions from each paycheck in the amount
        of ____% of my Compensation on each payday (from 0 to 15%) during the
        Offering Period in accordance with the Employee Stock Purchase Plan.
        (Please note that no fractional percentages are permitted.)

3.      I understand that said payroll deductions shall be accumulated for the
        purchase of shares of Common Stock at the applicable Purchase Price
        determined in accordance with the Employee Stock Purchase Plan. I
        understand that if I do not withdraw from an Offering Period, any
        accumulated payroll deductions will be used to automatically exercise my
        option.

4.      I have received a copy of the complete Employee Stock Purchase Plan. I
        understand that my participation in the Employee Stock Purchase Plan is
        in all respects subject to the terms of the Plan. I understand that my
        ability to exercise the option under this Subscription Agreement is
        subject to shareholder approval of the Employee Stock Purchase Plan.

5.      Shares purchased for me under the Employee Stock Purchase Plan should be
        issued in the name(s) of (Employee or Employee and Spouse only):
        ____________________________.

6.      I understand that if I dispose of any shares received by me pursuant to
        the Plan within 2 years after the Enrollment Date (the first day of the
        Offering Period during which I purchased such shares) or one year after
        the Exercise Date, I will be treated for federal income tax purposes as
        having received ordinary income at the time of such disposition in an
        amount equal to the excess of the fair market value of the shares at the
        time such shares were purchased by me over the price which I paid for
        the shares. I hereby agree to notify the Company in writing within 30
        days after the date of any disposition of my shares and I will make
        adequate provision for Federal, state or other tax withholding
        obligations, if any, which arise upon the disposition of the Common
        Stock. The Company may, but will not be obligated to, withhold from my
        compensation the amount necessary to meet any applicable withholding
        obligation including any withholding necessary to make available to the
        Company any tax deductions or



<PAGE>   11



        benefits attributable to sale or early disposition of Common Stock by
        me. If I dispose of such shares at any time after the expiration of the
        2-year and 1-year holding periods, I understand that I will be treated
        for federal income tax purposes as having received income only at the
        time of such disposition, and that such income will be taxed as ordinary
        income only to the extent of an amount equal to the lesser of (1) the
        excess of the fair market value of the shares at the time of such
        disposition over the purchase price which I paid for the shares, or (2)
        15% of the fair market value of the shares on the first day of the
        Offering Period. The remainder of the gain, if any, recognized on such
        disposition will be taxed as capital gain.

7.      I hereby agree to be bound by the terms of the Employee Stock Purchase
        Plan. The effectiveness of this Subscription Agreement is dependent upon
        my eligibility to participate in the Employee Stock Purchase Plan.

8.      In the event of my death, I hereby designate the following as my
        beneficiary(ies) to receive all payments and shares due me under the
        Employee Stock Purchase Plan:

                            1998 DIRECTOR OPTION PLAN


        1.     Purposes of the Plan. The purposes of this 1998 Director Option
Plan are to attract and retain the best available personnel for service as
Outside Directors (as defined herein) of the Company, to provide additional
incentive to the Outside Directors of the Company to serve as Directors, and to
encourage their continued service on the Board.

               All options granted hereunder shall be nonstatutory stock
options.

<PAGE>   3



                      (i) No person shall have any discretion to select which
Outside Directors shall be granted Options or to determine the number of Shares
to be covered by Options granted to Outside Directors.

                      (ii) Each Outside Director shall be automatically granted
an Option to purchase 9,000 Shares (the "First Option") on the effective date of
the Company's initial public offering ("IPO") of Common Stock registered with
the Securities and Exchange Commission.

                      (iii) Commencing in 1999, each Outside Director shall be
automatically granted an Option to purchase 9,000 Shares (the "Annual Option")
on the date of the annual stockholders' meeting of each year provided he or she
is then an Outside Director and if as of such date, he or she shall have served
on the Board for at least the preceding six (6) months.

                      (iv) Notwithstanding the provisions of subsection (ii) or
(iii) hereof, any exercise of an Option granted before the Company has obtained
shareholder approval of the Plan in accordance with Section 16 hereof shall be
conditioned upon obtaining such shareholder approval of the Plan in accordance
with Section 16 hereof.

                      (v) The terms of a First Option granted hereunder shall be
as follows:

                             (A) the term of the First Option shall be ten (10)
years.

                             (B) the First Option shall be exercisable only
while the Outside Director remains a Director of the Company, except as set
forth in Sections 8 and 10 hereof.

                             (C) the exercise price per Share shall be 100% of
the initial price to public of the Shares offered in the IPO as set forth in
the final prospectus included within the registration statement on Form S-1
filed with the Securities and Exchange Commission.

                             (D) subject to Section 10 hereof, the First Option
shall become exercisable as to one-twelfth (1/12) of the Shares subject to the
First Option at the end of each full month commencing upon the last date of the
month in which the First Option is granted, provided that the Optionee continues
to serve as a Director on such dates.

                      (vi) The terms of each Annual Option granted hereunder
shall be as follows:

                             (A) the term of the Annual Option shall be ten (10)
years.

                             (B) the Annual Option shall be exercisable only
while the Outside Director remains a Director of the Company, except as set
forth in Sections 8 and 10 hereof.

                             (C) the exercise price per Share shall be 100% of
the Fair Market Value per Share on the date of grant of the Annual Option.



                                       -3-

<PAGE>   4



                             (D) subject to Section 10 hereof, the Annual Option
shall become exercisable as to one-twelfth (1/12) of the Shares subject
to the Annual Option at the end of each full month after the date of grant
commencing upon the last date of the month in which the Option is granted,
provided that the Optionee continues to serve as a Director on such dates.

                      (vii) In the event that any Option granted under the Plan
would cause the number of Shares subject to outstanding Options plus the number
of Shares previously purchased under Options to exceed the Pool, then the
remaining Shares available for Option grant shall be granted under Options to
the Outside Directors on a pro rata basis. No further grants shall be made until
such time, if any, as additional Shares become available for grant under the
Plan through action of the Board or the shareholders to increase the number of
Shares which may be issued under the Plan or through cancellation or expiration
of Options previously granted hereunder.

        5.     Eligibility. Options may be granted only to Outside Directors.
All Options shall be automatically granted in accordance with the terms set
forth in Section 4 hereof. The Plan shall not confer upon any Optionee any right
with respect to continuation of service as a Director or nomination to serve as
a Director, nor shall it interfere in any way with any rights which the Director
or the Company may have to terminate the Director's relationship with the
Company at any time.

        6.     Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board or its approval by the shareholders of the
Company as described in Section 16 of the Plan. It shall continue in effect for
a term of ten (10) years unless sooner terminated under Section 11 of the Plan.

        7.     Form of Consideration. The consideration to be paid for the
Shares to be issued upon exercise of an Option, including the method of payment,
shall consist of (i) cash, (ii) check, (iii) other shares which (x) in the case
of Shares acquired upon exercise of an Option, have been owned by the Optionee
for more than six (6) months on the date of surrender, and (y) have a Fair
Market Value on the date of surrender equal to the aggregate exercise price of
the Shares as to which said Option shall be exercised, (iv) consideration
received by the Company under a cashless exercise program implemented by the
Company in connection with the Plan, or (v) any combination of the foregoing
methods of payment.

        8.     Exercise of Option.

               (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable at such times as are set forth in Section
4 hereof; provided, however, that no Options shall be exercisable until
shareholder approval of the Plan in accordance with Section 16 hereof has been
obtained.

               An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to



                                       -4-

<PAGE>   5



exercise the Option and full payment for the Shares with respect to which the
Option is exercised has been received by the Company. Full payment may consist
of any consideration and method of payment allowable under Section 7 of the
Plan. Until the issuance (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. A share certificate for the number
of Shares so acquired shall be issued to the Optionee as soon as practicable
after exercise of the Option. No adjustment shall be made for a dividend or
other right for which the record date is prior to the date the stock certificate
is issued, except as provided in Section 10 of the Plan.

               Exercise of an Option in any manner shall result in a decrease in
the number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

               (b) Termination of Continuous Status as a Director. Subject to
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or total and permanent disability (as
defined in Section 22(e)(3) of the Code)), the Optionee may exercise his or her
Option, but only within three (3) months following the date of such termination,
and only to the extent that the Optionee was entitled to exercise it on the date
of such termination (but in no event later than the expiration of its ten (10)
year term). To the extent that the Optionee was not entitled to exercise an
Option on the date of such termination, and to the extent that the Optionee does
not exercise such Option (to the extent otherwise so entitled) within the time
specified herein, the Option shall terminate.

               (c) Disability of Optionee. In the event Optionee's status as a
Director terminates as a result of total and permanent disability (as defined in
Section 22(e)(3) of the Code), the Optionee may exercise his or her Option, but
only within twelve (12) months following the date of such ter mination, and only
to the extent that the Optionee was entitled to exercise it on the date of such
termination (but in no event later than the expiration of its ten (10) year
term). To the extent that the Optionee was not entitled to exercise an Option on
the date of termination, or if he or she does not exercise such Option (to the
extent otherwise so entitled) within the time specified herein, the Option shall
terminate.

               (d) Death of Optionee. In the event of an Optionee's death, the
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee was
entitled to exercise it on the date of death (but in no event later than the
expiration of its ten (10) year term). To the extent that the Optionee was not
entitled to exercise an Option on the date of death, and to the extent that the
Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.



                                       -5-

<PAGE>   6



        9.     Non-Transferability of Options. The Option may not be sold,
pledged, assigned, hypothecated, transferred, or disposed of in any manner other
than by will or by the laws of descent or distribution and may be exercised,
during the lifetime of the Optionee, only by the Optionee.

        10.    Adjustments Upon Changes in Capitalization, Dissolution, Merger
or Asset Sale.

               (a) Changes in Capitalization. Subject to any required action by
the shareholders of the Company, the number of Shares covered by each
outstanding Option, the number of Shares which have been authorized for issuance
under the Plan but as to which no Options have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option, as well
as the price per Share covered by each such outstanding Option, and the number
of Shares issuable pursuant to the automatic grant provisions of Section 4
hereof shall be proportionately adjusted for any increase or decrease in the
number of issued Shares resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of issued Shares effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of Shares
subject to an Option.

               (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it shall terminate immediately prior to the
consummation of such proposed action.

               (c) Merger or Asset Sale. In the event of a merger of the Company
with or into another corporation or the sale of substantially all of the assets
of the Company, outstanding Options shall become fully vested and exercisable,
including as to Shares for which it would not otherwise be exercisable. In such
event the Board shall notify the Optionee that the Option shall be fully
exercisable for a period of thirty (30) days from the date of such notice, and
upon the expiration of such period the Option shall terminate.

        11.    Amendment and Termination of the Plan.

               (a) Amendment and Termination. The Board may at any time amend,
alter, suspend, or discontinue the Plan, but no amendment, alteration,
suspension, or discontinuation shall be made which would impair the rights of
any Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with any applicable
law, regulation or stock exchange rule, the Company shall obtain shareholder
approval of any Plan amendment in such a manner and to such a degree as
required.

               (b) Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated.



                                       -6-

<PAGE>   7


        12.    Time of Granting Options. The date of grant of an Option shall,
for all purposes, be the date determined in accordance with Section 4 hereof.

        13.    Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated there
under, state securities laws, and the requirements of any stock exchange upon
which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

               As a condition to the exercise of an Option, the Company may
require the person exercising such Option to represent and warrant at the time
of any such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares, if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

               Inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company's counsel to
be necessary to the lawful issuance and sale of any Shares hereunder, shall
relieve the Company of any liability in respect of the failure to issue or sell
such Shares as to which such requisite authority shall not have been obtained.

        14.    Reservation of Shares. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

        15.    Option Agreement. Options shall be evidenced by written option
agreements in such form as the Board shall approve.

        16.    Shareholder Approval. The Plan shall be subject to approval by
the shareholders of the Company within twelve (12) months after the date the
Plan is adopted. Such shareholder approval shall be obtained in the degree and
manner required under applicable state and federal law and any stock exchange
rules.

              C.    Landlord agrees promptly to notify Tenant of the placing of
                    any mortgage or trust deed against the leasehold estate of
                    which the Building forms a part and Tenant agrees in the
                    event of any act or omission by Landlord which would give
                    Tenant the right to terminate this Lease or to claim a
                    partial or total eviction, Tenant shall not exercise any
                    such right (i) until it has notified in writing the holder
                    of any mortgage which at the time shall be a lien on the
                    Building, if the name and address of such holder shall
                    previously have been furnished by written notice to Tenant,
                    of such act or omission, and (ii) until a reasonable period,
                    not exceeding thirty (30) days, for commencing the remedying
                    of such act or omission shall have lapsed following the
                    giving of such notice, and (iii) such holder, with
                    reasonable diligence shall not have so commenced and
                    continued to remedy such act or omission or to cause the
                    same to be remedied. During the period between the giving of
                    such notice and the remedying of such act or omission, the
                    rental herein recited shall be abated and apportioned to the
                    extent that any part of the Building shall be untenantable.

              D.    If such mortgage be foreclosed, upon request of the
                    mortgagee or trustee, Tenant will attorn to the purchaser at
                    any foreclosure sale thereunder and will execute such
                    instruments as may be necessary or appropriate to evidence
                    such attornment. Likewise Tenant will attorn to the
                    leasehold mortgagee in the event said leasehold mortgagee
                    should ever become the owner of the leasehold estate covered
                    by its mortgage or should become the owner of any new lease
                    in replacement or substitution of such leasehold estate.

furniture, equipment, machinery, fixtures, and all other items of personal
property of every kind and description from the Building prior to the end of the

class to the original construction, shall be of a design approved in writing by
the Landlord, shall be performed pursuant to plans and specifications approved
by the Landlord and in accordance with all provisions applicable to said work
and all other provisions of this Lease. The restoration shall be commenced

Tenant shall diligently complete the restoration. The Landlord agrees to oversee
and supervise all construction required under this paragraph 15; without
altering or modifying the Tenant's responsibilities hereunder.

           No partial destruction or damage to the Building or any part thereof
shall permit the Tenant to surrender this Lease or relieve the Tenant from its
obligations to pay rent or from any other obligations hereunder. The Tenant
waives any rights now or in the future conferred




<PAGE>   10

                                       -8-

rebate, refund, suspension, diminution, abatement, or reduction of rent on
account of any partial destruction or damage to the Building.

casualty, the Tenant shall promptly notify the Landlord, and, at the Tenant's
sole discretion, restore, replace, repair or rebuild the Building in accordance
with the provisions of this paragraph, or terminate this Lease. In the event the
Tenant elects to terminate this Lease, the Tenant shall, at the Tenant's sole
expense, restore the building site to its condition as of the date hereof, prior
to construction, to the satisfaction of Landlord.

           16. Holding Over. If the Tenant retains possession of the Building or
any part thereof, by lapse of time or otherwise, after the termination of this
Lease, the Tenant shall pay the Landlord rent at double the rate payable for the
year immediately preceding said holdover computed on per month basis, for the
time the Tenant thus remains in possession. The provisions of this paragraph do
not waive the Landlord's rights of re-entry or any other right hereunder. Any
retention of the Building after the termination of this lease or any extension
thereof shall be considered as a month-to-month holdover unless otherwise agreed
to in writing by both parties.

           17. Landlord's Remedies. All rights and remedies of the Landlord
herein enumerated shall be cumulative, and this Lease shall not exclude any
other right or remedy allowed herein or by law. If any provision hereof shall be
held invalid or unenforceable, the remaining provisions hereof shall continue
valid, enforceable and applicable.

              A.    If the Tenant defaults in the payment of base rent,
                    additional rent, or with regard to the payment of any other
                    sums due hereunder and if said default is not remedied
                    within ten (10) days after written demand is made by
                    Landlord, then in any such event, Landlord may, if the
                    Landlord so elects but not otherwise, either forthwith
                    terminate this Lease and the Tenant's right to possession of
                    the Building, or, without terminating this Lease, forthwith
                    terminate the Tenant's right to possession of the Building
                    and the Landlord may exercise any and all remedies available
                    to it under Iowa law, including but not limited to, the
                    foreclosure of its Landlord's lien against all tangible
                    personal property excepting property that is confidential or
                    otherwise proprietary in nature such as patents, copyrights,
                    trade secrets, software programs, data and the like of the
                    Tenant maintained within the Building.

              B.    If the Tenant defaults in the prompt and full performance of
                    any other provision of this Lease; and if such default is
                    not remedied or prompt and full performance is not
                    accomplished by Tenant or Tenant has not promptly instituted
                    and is not vigorously pursuing such remedies as are
                    necessary to rectify such default within thirty days after
                    written demand is made by Landlord, or if the Tenant
                    abandons the Building, then and in any such event, the
                    Landlord may, if the Landlord so elects but not otherwise,
                    forthwith terminate this Lease and the Tenant's right to the
                    Building or without terminating this Lease, forthwith
                    terminate the Tenant's right to possession of the Building

                    Landlord under Iowa law, including but not limited to the
                    foreclosure of its Landlord's lien as limited above.

              C.    Upon any termination of this Lease, whether by lapse of time
                    or otherwise, or upon termination of the Tenant's right to
                    possession without termination of the Lease, the Tenant
                    shall immediately surrender possession and vacate the
                    Building and deliver possession thereof to the Landlord, and
                    the Tenant hereby grants to the Landlord full and free
                    license to enter the Building with or without process of
                    law, and to repossess and remove any and all property
                    therefrom using such force as may be necessary, without
                    being deemed guilty of trespass, eviction, or forcible entry
                    or detainer, and without relinquishing the Landlord's right
                    to rent or any other right given to the Landlord hereunder
                    or by operation of law.

                    or retaken from storage by the Tenant within 60 days after
                    the end of the term, however, terminated, or any extension
                    thereof, shall be conclusively deemed to have been
                    forever abandoned by the Tenant.

              E.    If Tenant is adjudicated to be bankrupt or is found
                    insolvent in any court of record, or if a receiver or
                    trustee for the benefit of Tenant's creditors is appointed,
                    Landlord at its sole option may terminate this Lease without
                    notice and shall be entitled to damages as provided by law
                    or the terms hereof, provided, however, that such
                    adjudication, finding or appointment is not set aside within
                    30 days or an appeal therefrom shall not be prosecuted
                    within said 30 days and said appeal is either pending or is
                    concluded with the determination that Tenant is not bankrupt
                    or insolvent.

              F.    If Tenant should default under the terms of this Lease,
                    Landlord shall be entitled to all reasonable costs, charges,
                    expenses, and attorneys' fees incurred by Landlord in
                    connection therewith.

              G.    Tenant hereby pledges and assigns to Landlord subject to
                    purchase money security interests and prior perfected
                    security interests all of the furniture, fixtures, goods,
                    and tangible personal property of Tenant except that
                    property excepted in paragraph 17A above, which shall or may
                    be brought or put on the Building as security for the
                    payment of the rent herein reserved and Tenant agrees that
                    said lien hereby created by operation of law may be enforced
                    by foreclosure or otherwise at the election of the Landlord.
                    Tenant agrees to execute any and all financing statements,
                    security agreements and other forms necessary to perfect
                    this lien.

              H.    Tenant hereby waives and renounces any and all exemption
                    rights it may have now, or hereafter, under or by virtue of
                    the constitution and laws of the state in which the Building

                    or of the United States, as against the payment of said
                    rental or any portion hereof, or any other obligation or

                    counterclaim brought by either of the parties hereto against
                    the other on any matter whatsoever, arising out of or in any
                    way connected with this Lease, the relationship of Landlord
                    and Tenant, Tenant's use or occupancy of said Building, or
                    any claim of injury or damage, and any emergency statutory
                    or any other statutory remedy. It is further mutually agreed
                    that in the event Landlord commences any summary proceeding
                    for nonpayment of rent, Tenant will not interpose any
                    counterclaim of whatever nature or description in any such
                    proceeding.

              J.    Tenant hereby expressly waives any and all rights of
                    redemption granted by or under any present or future laws in
                    the event of Tenant being evicted or dispossessed for any
                    cause, or in the event of Landlord obtaining possession of
                    Building, by reason of the violation by Tenant of any of the

               G.   The heating, venting, and air conditioning units will be in

improvements as are shown by the plans and specifications prepared by John Rice
R.A. dated August 29, 1994 and by this reference made a part hereof.

           All interior improvements shall be completed by the Tenant consistent
with floor plans, specifications, and descriptions of materials provided by the
Tenant to the Landlord, and to be approved by the Landlord. The Landlord agrees
to advance the costs of the Tenant's improvements in an amount not to exceed
$60,000.00, and the Tenant agrees to repay said $60,000.00 at the rate of
$12,000.00 per year without interest until all sums are paid in full. The
parties agree to execute all necessary notes, security agreements, and financing
statements to provide the Landlord with security for the repayment of said sum.
The Landlord and Tenant agree to complete its respective improvements in a
timely fashion. The Landlord shall commence construction on or about November 2,
1994. The Tenant shall provide Landlord with plans and specifications for Tenant
improvements to be approved by Landlord which improvements shall be
substantially completed within 90 days from the date Landlord releases the
Building to Tenant for construction of Tenant improvements.

           19. Option to Renew. The Tenant shall have one option to renew the
term of this Lease for one five-year term, which term shall commence immediately
upon the expiration of the original term of this Lease. Said extension shall be
upon the same terms and conditions contained herein, except for the rental rate
described in this paragraph. In the event the Tenant desires to exercise its
option to renew this lease, the Tenant shall notify the Landlord, in writing,
not less than 120 days prior to the expiration of the term hereof. During the
option period, the rent payable shall equal the rent described above,
($84,033.60 annually), adjusted by the change in the Bureau of Labor Statistics

month immediately preceding the end of the initial lease term from the index
(expressed as a percentage or otherwise) for the month of October 1994. If
publication of that index is terminated, a substantially equivalent successor
thereto shall be used to determine the adjustment in rent during the option
period.

                                      -13-


           20. Environmental Matters. Tenant shall comply with all applicable
environmental rules, regulations, and laws and the Tenant shall indemnify,
defend and hold Landlord harmless from and against any and all claims,
judgments, damages, penalties, fines, costs, liabilities, and losses (including
reasonable attorneys' fees), arising out of a breach of or violation of any
applicable environmental laws. The Tenant shall not cause any hazardous
material, as described by state or federal law, to be used, generated, stored,
or disposed of on, about, or under or transported to or from the building,
without first receiving the landlord's written consent, which consent may be
withheld for any reason and revoked at any time. The Tenant acknowledges that
the Landlord shall have no liability with respect to violations of the
provisions of this paragraph.

           21. Subletting and Assignment. For purposes of this paragraph, any
transfer of stock, change in equity ownership within the Tenant or any change of
the Tenant's capital structure shall constitute an assignment or subletting,
with the exception of changes resulting from public offerings and other changes
where less than 49% of the Tenant's equity ownership has been transferred. With
the exception stated above, the Tenant shall not assign or sublet this Lease or
any part of the Building without the prior written consent of the Landlord,
which consent shall not be unreasonably withheld under the following conditions:

               A.   The assignee is at least as creditworthy, based upon
                    financial statements submitted to the Landlord, as the
                    Tenant.

               B.   The assignee shall agree to abide by all the terms and
                    conditions of this Lease.

               C.   There shall be no defaults under the terms of this Lease at
                    that time.

           Any assignment or subletting by the Tenant contrary to the terms
hereof shall have the effect of accelerating all sums due hereunder during the
remaining term of this Agreement, and shall constitute a default hereunder,
thereby entitling Landlord to pursue any and all remedies available to it. No
assignment or sublease shall relieve the Tenant of its obligations hereunder.

           22. Notices. All notice to be given by one party to the other party
under this Lease shall be given in written form and mailed or delivered to the
following:

              A.    To the Landlord, 1400 Highway 13 S.E., Cedar Rapids, Iowa
                    52406-2577, or to such other person at such other address
                    designated by Notice sent to Tenant and after commencement
                    of the term of the address to which rent is payable.



<PAGE>   16

                                      -14-

              B.    To the Tenant at the place set forth in the Schedule until
                    Tenant takes possession of the Building, and thereafter at
                    the Building or at such other address designated by notice
                    to the Landlord.

           Mailed notices shall be sent by United States mail, Certified or
Registered, postage prepaid. Such notice shall be deemed to have been given upon
depositing in the United States mail.

           23. Quiet Possession. So long as Tenant shall observe and perform the
covenants and agreements binding on it hereunder, Tenant shall at all times
during the term herein granted peacefully and quietly have and enjoy the
possession of the Building without any encumbrance or hindrance by, from or
through the Landlord, its successors or assigns.

           24. Miscellaneous.

               A.   Each provision hereof shall extend to and shall, as the case
                    may require, bind and inure to the benefit of the Landlord
                    and the Tenant and their respective heirs, legal
                    representatives and successors, and assigns.

               B.   All amounts owed to the Landlord hereunder, for which the
                    date of payment is not expressly fixed herein, shall be paid
                    within thirty (30) days from the date the Landlord renders
                    statements of account therefore and shall bear interest at
                    the rate of ten (10%) per annum thereafter until paid.

               C.   Tenant shall deliver to Landlord or to its mortgagee,
                    auditors, or prospective purchaser when requested by
                    Landlord, a certificate to the effect that Landlord is not
                    in default therein, or stating specifically any exceptions
                    thereto. Failure to give such a certificate within two (2)
                    weeks after written request shall be conclusive evidence
                    that the Lease is in full force and effect and Landlord is
                    not in default and Tenant shall be estopped from asserting
                    any defaults known to Tenant at that time.

               D.   In the event that all or a substantial portion of the
                    Building is taken by eminent domain so that the Building
                    cannot be reasonably used by Tenant for the purposes for
                    which it is demised, then at the option of either party the
                    Lease may be terminated, effective as of the date of the
                    taking. In this event, the

                    entire award shall be paid to and retained by Landlord
                    excepting however, that Tenant may receive therefrom any
                    portion paid on account of its moving expenses.

      1. LEASING AGREEMENT AND TERM. Landlord hereby leases to Tenant, and 
Tenant hereby leases the Premises, from the Landlord for a term commencing

by the Tenant only for the uses described herein.

      2. USE OF PREMISES. The Premises shall be occupied and used by the Tenant
only for those purposes and uses allowable hereunder. The Tenant's use, and this

CORPORATION, as "Lessor" and MYRIAD DEVELOPERS, L.C., as "Lessee," a copy of

and in compliance with the provisions hereof.

      3. RENT. Tenant shall pay to Landlord at Landlord's office in the City of
Cedar Rapids, Iowa or to such other person or at such other place as directed
from time to time by notice to the Tenant from Landlord the annual base rent as

Schedule. Each monthly installment shall be payable in advance promptly on the
first day of each calendar month during the term of this Lease and shall bear
interest at the rate of 10 percent (10%) per annum from and after the l0th day
of the month if not then paid until the date when paid. If the term should
commence or terminate on a day other than the first day of the month, then the
rent for the first and last month shall be prorated for such fractional month.
All rent payable by Tenant hereunder shall be net to Landlord. All expenses and
obligations of every kind and nature whatsoever relating to the Building, which
may arise or become due during the term of this Lease including, but not limited
to, taxes, utilities, insurance, and maintenance shall be paid by the Tenant and
Tenant shall indemnify and hold the Landlord harmless from said expenses. This
Lease is a net Lease and Landlord shall have no expenses associated with the 
Building.

the schedule, the Tenant shall pay, as additional rent, the following:

            A.    Taxes and Special Assessments. The Tenant shall pay, as
                  additional rent, its proportionate share of the real estate
                  taxes accruing from the commencement date and all special
                  assessments due and payable during the Lease term, and a
                  prorated share of all taxes and special assessments becoming
                  payable after the termination of the Lease for

<PAGE>   3

                                       -3-

                  periods during the term of the Lease, which amounts shall be
                  paid monthly with the base rent. The Landlord shall notify the
                  Tenant of any increases in taxes during the term of this
                  Lease. All other sums required to be paid by tenant hereunder
                  shall be deemed additional rent. Tenant's proportionate share
                  shall be rentable square feet (11,SOO square feet) divided by
                  total rentable square footage in the building (14,904 square
                  feet) times the actual taxes for building number two and taxes
                  for the associated parking.

            B.    Insurance. The Tenant shall pay and reimburse the Landlord,
                  upon request by the Landlord, its proportionate share of the
                  cost of insurance procured and maintained by the Landlord
                  hereunder as per section 11 of the Agreement based on the
                  square footage of the Leased Premises compared to the total
                  square footage of the Building. All sums requested hereunder
                  by the Landlord shall be paid by the Tenant within 15 days
                  thereof, or the Landlord has the right to require the Tenant
                  to pay one-twelfth of the cost of all insurance monthly with
                  the base rent. Tenant's proportionate share shall be rentable
                  square feet (11,500 square feet) divided by total rentable
                  square footage in the building (14,904 square feet) times the
                  cost of insurance procured and maintained by the Landlord as
                  described above.

            C.    Maintenance. The Tenant shall pay its proportionate share of
                  all the costs of maintaining, repairing, operating and
                  replacing all improvements to the real estate on which the

                  designated as Landlord under this Lease, shall exist only so
                  long as such trustee, mortgagee, purchaser or owner is the
                  owner of the subject real estate and such liability shall not
                  continue or survive after further transfer of ownership.

            C.    Landlord agrees promptly to notify Tenant of the placing of
                  any mortgage or trust deed against the leasehold estate of
                  which the Building forms a part and Tenant agrees in the event
                  of any act or omission by Landlord which would give Tenant the
                  right to terminate this Lease or to claim a partial or total
                  eviction, Tenant shall not exercise any such right (i) until
                  it has notified in writing the holder of any mortgage which at
                  the time shall be a lien on the Building, if the name and
                  address of such holder shall previously have been furnished by
                  written notice to Tenant, of such act or omission, and (ii)
                  until a reasonable period, not exceeding thirty (30) days, for
                  commencing the remedying of such act or omission shall have
                  lapsed following the giving of such notice, and (iii) such
                  holder, with reasonable diligence shall not have so commenced
                  and continued to remedy such act or omission or to cause the
                  same to be remedied. During the period between the giving of
                  such notice and the remedying of such act or omission, the
                  rental herein recited shall be abated and apportioned to the
                  extent that any part of the Building shall be untenantable.

            D.    If such mortgage be foreclosed, upon request of the mortgagee
                  or trustee, Tenant will attorn to the purchaser at any
                  foreclosure sale thereunder and will execute such instruments
                  as may be necessary or appropriate to evidence such
                  attornment. Likewise Tenant will attorn to the leasehold
                  mortgagee in the event said leasehold mortgagee should ever
                  become the owner of the leasehold estate covered by its
                  mortgage or should become the owner of any new lease in
                  replacement or substitution of such leasehold estate.

                  this Lease or relieve the Tenant from its obligations to pay
                  rent or from any other obligations hereunder. The Tenant
                  waives any rights now or in the future conferred upon it by

                  rebate, refund, suspension, diminution, abatement, or

                  or otherwise, or upon termination of the Tenant's right to
                  possession without termination of the Lease, the Tenant shall
                  immediately surrender possession and vacate the Premises and
                  deliver possession thereof to the Landlord, and the Tenant
                  hereby grants to the Landlord full and free license to enter
                  the Premises with or without process of law, and to repossess
                  and remove any and all property therefrom using such force as
                  may be necessary, without being deemed guilty of trespass,
                  eviction, or forcible entry or detainer, and without
                  relinquishing the Landlord's right to rent or any other right
                  given to the Landlord hereunder or by operation of law.

                  property. The Tenant shall pay to the Landlord, upon demand,
                  any and all reasonable expenses incurred in such removal and
                  all reasonable storage charges against such property as long
                  as the same shall be in the Landlord's possession or under the
                  Landlord's control. Any such property of the tenant not
                  removed from the Premises or retaken from storage by the
                  Tenant within 60 days after the end of the term, however,
                  terminated, or any extension thereof, shall be conclusively
                  deemed to have been forever abandoned by the Tenant.

            E.    If Tenant is adjudicated to be bankrupt or is found insolvent
                  in any court of record, or if a receiver or trustee for the
                  benefit of Tenant's creditors is appointed, Landlord at its
                  sole option may terminate this Lease without notice and shall
                  be entitled to damages as provided by law or the terms hereof,
                  provided, however, that such adjudication, finding or
                  appointment is not set aside within 30 days or an appeal
                  therefrom shall not be prosecuted within said 30 days and said
                  appeal is either pending or is concluded with the
                  determination that Tenant is not bankrupt or insolvent.

            F.    If Tenant should default under the terms of this Lease,
                  Landlord shall be entitled to all reasonable costs, charges,
                  expenses, and attorneys' fees incurred by Landlord in
                  connection therewith.

      18. Tenant's Remedies Upon Default. If the Landlord is in default in
performing any of the terms or provisions of this Lease and the Landlord fails
to cure such default within thirty (30) days after receipt of written notice
from the Tenant stating with particularity the nature and extent of the default
(provided the nature of the default is of a character as to require more than 30
days to cure, the Landlord shall have an additional reasonable period of time to
cure such default if the Landlord has commenced to cure such default within 30
days as is diligently pursuing the remedies or steps necessary to cure or
correct such default), the Tenant shall have the following rights and remedies,
which distinct and separate:

            A.    The Tenant may cure the default, and the Landlord shall
                  reimburse the Tenant, upon demand, for all the Tenant's direct
                  costs;

            D.    The Tenant shall have the right to exercise any and all rights

90 days from the date Landlord releases the Premises to Tenant for construction
of Tenant improvements. The Landlord agrees to advance the costs of the Tenant's
improvements in an amount not to exceed $40,000.00 and the Tenant agrees to
repay said $40,000.00 as per the attached amortization schedule with three
percent interest per annum (amortization table attached) until all sums are paid

      20. Option to Renew. The Tenant shall have one option to renew the term of
this lease for one five-year term, which term shall commence immediately upon
the expiration of the original term of this Lease. Said extension shall be upon
the same terms and conditions contained herein, except for the rental rate
described in this paragraph. In the event the Tenant desires to exercise its
option to renew this lease, the Tenant shall notify the Landlord, in writing,
not less than 120 days prior to the expiration of the term hereof. During the
option period the rent payable shall equal the rent described above, $96,600.00
annually, adjusted by the change in the Bureau of Labor Statistics Consumer
Price Index, U.S. City Average, All Urban Consumers (C.P.I.U.) for the month
immediately preceding the end of the initial lease term from the index
(expressed as a percentage or otherwise) for the month of October 1994. If
publication of that index is terminated, a substantially equivalent successor
thereto shall be used to determine the adjustment in rent during the option
period.

      21. Environmental Matters. Tenant shall comply with all applicable
environmental rules, regulations, and laws and the Tenant shall indemnify,
defend and hold Landlord and the Iowa Research Park Corporation harmless from
and against any and all claims, judgments, damages, penalties, fines, costs,
liabilities, and losses (including reasonable attorneys' fees), arising out of
a breach of or violation of any applicable environmental laws. The Tenant shall
not cause any hazardous material, as described by state or federal law, to be
used, generated, stored, or disposed of on, about, or under or transported to or
from the Building, without first receiving the landlord's written consent, which
consent may be withheld for any reason and revoked at any time. The Tenant
acknowledges that the Landlord shall have no liability with respect to
violations of the provisions of this paragraph.

      22. Subletting and Assignment. For purposes of this paragraph, any
transfer of stock, change in equity ownership within the Tenant or any change of
the Tenant's capital structure shall constitute an assignment or subletting,
with the exception of changes resulting from public offerings and other changes
where less than 49% of the Tenant's equity ownership has been transferred. With
the exception stated above, the Tenant shall not assign or sublet this Lease or
any part of the Building without the prior written consent of the Landlord,
which consent shall not be unreasonably withheld under the following conditions:

            A.    The assignee is at least as creditworthy, based upon financial
                  statements submitted to the Landlord, as the Tenant.

            B.    The assignee shall agree to abide by all the terms and
                  conditions of this Lease.

            C.    There shall be no defaults under the terms of this Lease at
                  that time.

<PAGE>   15

                                      -15-

      Any assignment or subletting by the Tenant contrary to the terms hereof
shall have the effect of accelerating all sums due hereunder during the
remaining term of this Agreement, and shall constitute a default hereunder,
thereby entitling Landlord to pursue any and all remedies available to it. No
assignment or sublease shall relieve the Tenant of its obligations hereunder.

      23. Notices. All notice to be given by one party to the other party under
this Lease shall be given in written form and mailed or delivered to the
following:

            A.    To the Landlord, 1400 Highway 13 S.E., Cedar Rapids, Iowa
                  52403-9803, or to such other person at such other address
                  designated by Notice sent to Tenant and after commencement of
                  the term of the address to which rent is payable.

            B.    To the Tenant at the place set forth in the Schedule until
                  Tenant takes possession of the Building, and thereafter at the
                  Building or at such other address designated by notice to the
                  Landlord.

      Mailed notices shall be sent by United States mail, Certified or
Registered, postage prepaid. Such notice shall be deemed to have been given upon
depositing in the United States mail.

      24. Quiet Possession. So long as Tenant shall observe and perform the
covenants and agreements binding on it hereunder, Tenant shall at all times
during the term herein granted peacefully and quietly have and enjoy the
possession of the Premises without any encumbrance or hindrance by, from or
through the Landlord, its successors or assigns.

      25. Miscellaneous.

            A.    Each provision hereof shall extend to and shall, as the case
                  may require, bind and inure to the benefit of the Landlord and
                  the Tenant and their respective heirs, legal representatives
                  and successors, and assigns.

            B.    All amounts owed to the Landlord hereunder, for which the date
                  of payment is not expressly fixed herein, shall be paid within
                  thirty (30) days from the date the Landlord renders statements
                  of account therefore and shall bear interest at the rate of
                  ten (10%) per annum thereafter until paid.

            C.    Tenant shall deliver to Landlord or to its mortgagee,
                  auditors, or prospective purchaser when requested by Landlord,
                  a certificate to the effect that Landlord is not in default
                  therein, or stating specifically any exceptions thereto.
                  Failure to

<PAGE>   16

                                      -16-

                  give such a certificate within two (2) weeks after written
                  request shall be conclusive evidence that the Lease is in full
                  force and effect and Landlord is not in default and Tenant
                  shall be estopped from asserting any defaults known to Tenant
                  at that time.

            D.    In the event that all or a substantial portion of the Premises
                  is taken by eminent domain so that the Premises cannot be
                  reasonably used by Tenant for the purposes for which it is
                  demised, then at the option of either party the Lease may be
                  terminated, effective as of the date of the taking. In this
                  event, the entire award shall be paid to and retained by
                  Landlord excepting however, that Tenant may receive therefrom
                  any portion paid on account of its moving expenses.

Agreement, ITC agrees to manufacture and sell to Urosurge all Products ordered
by Urosurge during the term of this Agreement. Unless otherwise agreed by the
parties, ITC shall sell the Products exclusively to Urosurge.

           3.2 Exclusive Supplier. During the term of this Agreement, ITC shall
be the exclusive supplier of Products to Urosurge for sale in the U.S. ITC shall
be the exclusive supplier outside the U.S., as soon as practicable, provided ITC

                                       -2-
<PAGE>   3


individual foreign countries or regulatory bodies. ITC shall use its best
efforts to provide technical information and physical test date as requested by
Urosurge in support of such efforts. ITC shall ensure that U.S. and foreign
manufacturing facilities conform to European Community (EC) and ISO standards
requirements when necessary. Notwithstanding the foregoing, if ITC is unable to
supply Urosurge's requirements for Products, Urosurge shall have the right to
purchase the Products or any components from any other source without obligation
to ITC. In that event, ITC shall license the other source to manufacture the

business days of receipt. Within such ten (10) day period, ITC may only reject
an order which does not conform with the terms and conditions of this Agreement.
Notice of rejection must be sent to Urosurge by telex or fax, followed by
registered letter. If an order is neither confirmed nor rejected by ITC within
ten (10) business days of receipt, it shall be deemed to have been accepted.

           3.5 Delivery Date. Unless otherwise agreed in writing by the parties,
ITC shall deliver Products no later than five (5) days after the date specified
in an accepted purchase order, provided ITC receives such purchase order at
least ninety (90) days prior to the specified delivery date. If ITC receives a
purchase order less than ninety (90) days before the specified delivery date,
ITC shall use reasonable commercial efforts to deliver such Products on the
specified delivery date.

           3.6 Shipping. All Products subject to this Agreement shall be
suitably packed for shipment in containers adequate to insure safe arrival of

special packaging or finishing; provided, however, ITC agrees to pack any
special documentation regarding the Products requested by Urosurge, at no
additional charge. Shipment will be F.O.B., ITC's plant, Fremont, California.
All shipping papers and/or invoices shall include the purchase order number and
serial numbers of Products shipped.

           3.7 Terms and Conditions. This Agreement contains the exclusive terms
and conditions which shall apply to all purchases of Products by Urosurge. In
ordering and delivering Products, Urosurge and ITC may use their standard forms
but nothing in such forms shall amend or modify the terms of this Agreement. In
case of conflict between such forms and this Agreement, the terms of this
Agreement shall control.

4.         CANCELLATION AND RESCHEDULING

           4.1 Changes. Urosurge may cancel or reschedule for up to thirty (30)
days a purchase order previously accepted by ITC, provided Urosurge provides ITC
notice at least sixty (60) days prior to the specified delivery date. ITC will

such order, in whole or part, without any obligation or liability to ITC.

5.         PRICING

           5.1 Product Prices. Except as otherwise provided in this Section 51,
the price for Products subject to this Agreement shall be those listed on
attached Exhibit B. All prices are in United States dollars. The prices as set
forth on said Exhibit shall remain in effect and fixed during the term of this
Agreement. If during the term of this Agreement reduced prices are put into
effect by ITC, such reduced prices shall apply to released but unshipped
Products and all subsequent release orders issued hereunder. ITC warrants that
the prices charged Urosurge hereunder are not in excess of the lowest prices
charged by ITC to other purchasers of the similar Products in like quantities
and under similar circumstances.

           5.2 Taxes. All prices described herein are exclusive of federal,
state and local excise, sales, use and similar taxes. Urosurge shall be liable
for and shall pay all applicable




                                      -4-

<PAGE>   5

taxes invoiced by ITC, unless Urosurge provides ITC with a properly executed tax
exemption certificate prior to delivery.

6.         PAYMENT

           6.1 Payment. ITC shall issue Urosurge individual invoices for each
Product shipment. Each such invoice shall separately list the price of each
Product, taxes, transportation, shipping and insurance charges, and any special
packaging or finishing charges. Urosurge shall pay each invoice within thirty
(30) days of the date of such invoice or the delivery date, whichever is later.
Payment of an invoice shall not constitute implied acceptance of Products.

           6.2 Payment Method. Urosurge shall make payment to ITC for Products
by check or by wire transfer to an account specified by ITC.

           6.3 Overdue Payments. Payments more than thirty (30) days overdue

maximum amount allowed by law, whichever is less.

7.         FORECASTS

           On a quarterly basis thereafter Urosurge shall provide ITC with a
forecast of Urosurge's anticipated quarterly requirements of Products for the
following twelve (12) month period commencing on the date of such forecast. It
is understood that such forecast is not binding but Urosurge shall use all
reasonable efforts to make each forecast as accurate as possible, particularly
as it pertains to the six (6) months immediately following the date of such
forecast.

8.         PRODUCT QUALITY

           8.1 Quality Assurance. ITC agrees to assure the quality level of
Products through the use of a formal quality assurance program reasonably
acceptable to Urosurge. Such program shall require ITC to prepare and maintain
written records sufficient to enable Urosurge to trace the history of each
Product. Pursuant to such program, ITC shall place serial numbers on all
Products to enable the identification and tracing of Products. During the term
of the Agreement, Urosurge shall have the right to audit such quality assurance
program, at its expense, during regular business hours.

           8.2 Inspection. ITC shall conduct a final inspection and quality
control test on each Product prior to shipment to verify that such Products meet
and conform with the Specifications.



                                      -5-

<PAGE>   6

Each shipment of Products shall be accompanied by a quality assurance analytical
data sheet (the "Q.A. Data Sheet").

           8.3 Presence at Facility. During the first six (6) months during
which each Product is commercially manufactured for Urosurge and thereafter upon
reasonable written notice to ITC, Urosurge shall have the right to have its
representatives visit, from time to time, the facility at which such Product is
being manufactured, to verify ITC's compliance with the warranties in Section 10
below.

           8.4 Inspection and Acceptance. Urosurge shall have the right and ITC
shall cooperate to the fullest extent practicable in giving Urosurge an
opportunity to inspect the Products at all times and places including during the
period of manufacture. However, no inspection or test made prior to final
inspection and acceptance at Urosurge's facility shall relieve ITC of
responsibility for defects or other failure to supply conforming Products. Final
inspection and acceptance shall be at Urosurge's facility, and shall be
performed within a reasonable time after receipt of the Products.

           8.5 Latent Defects. It is understood that Products may have defects
("defects" meaning that such Products fail to conform to the applicable
Specifications or otherwise fail to conform to the warranties given by ITC
herein) which would not be discoverable upon reasonable physical inspection or
testing (the "Latent Defects"). As soon as either Urosurge or ITC becomes aware
of a Latent Defect in any Product it shall immediately notify the other party
and, at Urosurge's election, such Products shall be deemed non-conforming to the
Specifications and rejected as of the date of such notice.

9.         PRODUCT CHANGES

           9.1 Design Modifications. ITC shall have the right to make design
modifications to the Products to the extent such modifications do not affect the
form, fit, function, safety, reliability, or performance of a Product; provided,
however, that ITC shall notify Urosurge of any such modifications that
materially affect the form, fit, function, safety, reliability, or performance
of the Products. Within twenty (20) days after receiving any such notice from
ITC, Urosurge may disapprove of such design modifications. If Urosurge fails to
provide ITC with notice during such twenty (20) day period, Urosurge shall be
deemed to approve such modifications.

           9.2 Requested Modifications. Urosurge may request changes in the
design or operation of the Products relating to improvements, or the reliability
or serviceability of the Products. The parties shall discuss such modifications
in good faith; provided, however, it is understood that ITC shall have no
obligation to make such modifications to the Products.





                                      -6-
<PAGE>   7


           9.3 Mandatory Modifications. ITC shall make any changes to Products
required to comply with official requirements (including governmental regulation
or industrial standards). With respect to products changed to comply with such
requirements that have been ordered but not yet delivered, an appropriate
adjustment of the delivery date shall be agreed by the parties.

           9.4 Validation Units. In the event ITC proposes any change which
affecting form, fit, function, safety, reliability or performance of a Product,
ITC, at its expense, shall ship Urosurge ten (10) validation units incorporating
all such changes. Within ninety (90) days after receipt of such validation unit,
Urosurge shall notify ITC whether it approves or disapproves the proposed
changes. Failure by Urosurge to advise ITC that it disapproves a proposed change
within such ninety (90) days shall constitute Urosurge approval of such proposed
changes; provided, however, ITC shall not make the proposed changes until the
end of such ninety (90) day period or until Urosurge provides notice of its
approval of such changes, whichever occurs earlier.

10.        PRODUCT WARRANTY

           10.1 Express Warranty. ITC hereby warrants to Urosurge that:

                (a) on the date of shipment, all Products sold by ITC to
Urosurge hereunder are new, will comply with the Specifications for such
Products and any further specifications, standards and/or criteria agreed upon
by the parties, conform fully with the Q.A. Data Sheet provided for the
particular Product according to Section 8.2 hereof, and do not contain Latent
Defects;

                (b) Products purchased hereunder shall be free from defects in
material and workmanship for a period of twelve (12) months from the date of
shipment to Urosurge;

                (c) all of the Products sold hereunder shall have been
manufactured, packaged and stored and shipped in conformance with all applicable
current Good Manufacturing Practices which are in force or hereinafter adopted
by the FDA or any successor agency thereto;

                (d) title to all Products sold hereunder shall pass to Urosurge
as provided herein free and clear of any security interest, lien, or other
encumbrance;

                (e) ITC shall meet Urosurge's required shipment and/or delivery
schedule(s); and




                                      -7-

<PAGE>   8
                (f) the Products sold hereunder shall have been manufactured,
packaged and stored in facilities which are approved by the FDA at the time of
such manufacture, packaging and storage, to the extent such approval is required
by law.

                (a) If any Products purchased hereunder do not meet the
warranties specified herein or otherwise applicable, Urosurge may, at its option

nonconforming Products, (ii) return any nonconforming Products to ITC at ITC's
expense and recover from ITC the full market price thereof or (iii) replace or
correct the defective or nonconforming Products itself and charge ITC with the
cost of such correction. In the event that ITC fails to meet Urosurge's shipment
and/or delivery schedules Urosurge may, at its option, (i) procure equivalent or
similar replacement Products in a commercially reasonable manner from an
alternate source, charging ITC for the price differential, if any, or (ii) if an
alternate source is not available, recover from ITC all financial losses of any
nature resulting therefrom. The foregoing remedies are in addition to all other
remedies at law or in equity or under this Agreement and shall not be deemed to
be exclusive thereof. All warranties and remedies for breach thereof available
to Urosurge under this Agreement shall also be available to Urosurge's
customers.

                (b) No inspection or acceptance, approval or acquiescence by
Urosurge with respect to ITC's Products shall relieve ITC from any portion of
its warranty obligation, nor shall waiver by Urosurge of any specification
requirement for one or more items constitute a waiver of such requirements for
remaining items unless expressly agreed by Urosurge in writing.

           10.3 Exclusions. The express warranties set forth in Section 10.1
above shall not apply to defects to a Product which result from normal wear and
tear or improper, unqualified or unauthorized repair of Products.

           10.4 Disclaimer. EXCEPT FOR THE ABOVE EXPRESS WARRANTIES, ITC MAKES
NO WARRANTIES WITH RESPECT TO THE PRODUCTS, EXPRESS, IMPLIED, STATUTORY, OR IN
ANY OTHER PROVISION OF THIS AGREEMENT, AND ITC SPECIFICALLY DISCLAIMS ANY
IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

           10.5 Warranty Procedures. Subject to Section 10.2 above, Urosurge may
send Products with defects covered by the foregoing warranties to ITC's repair
center at an address specified by ITC from time to time. Urosurge shall request
authorization from ITC prior to the return of each defective Product for
replacement by ITC. Upon such request, ITC shall provide Urosurge with a
Material Return Authorization (MRA) tracer number to be prominently




                                      -8-

displayed on the shipping container for the defective Product. Once ITC
authorizes the return of any defective Product, Urosurge shall ship such Product
to the repair facility, freight prepaid, in its original shipping container or
in a container of equivalent protective constitution. If such defective Product
is received by ITC during the applicable warranty period, ITC shall, and shall
ship the replaced Product to Urosurge, freight prepaid.

           11.1 Confidential Information. Pursuant to this Agreement, each party
may disclose to the other certain proprietary technical or business information

                 which it shall be a party and which shall relate to the rights,
                 privileges or licenses granted hereunder, shall contain a
                 statement setting forth the date (if any) upon which LICENSEE's

                 termination at the address specified by LICENSEE in LICENSEE's
                 notice to CMCC of the sublicense. CMCC hereby agrees that, at
                 the request of the sublicensee as set forth below, provided the
                 sublicensee is not in breach under its sublicense, CMCC shall
                 grant to such sublicensee license rights and terms equivalent
                 to the sublicense rights and terms which the sublicense shall
                 have granted to said sublicensee; provided that the sublicensee
                 shall remain a sublicensee under this Agreement for a period of
                 at least sixty (60) days following receipt of notice from CMCC.
                 Such right shall be exercisable upon written notice from the
                 sublicensee to CMCC during said sixty (60) day period wherein
                 the sublicensee: (i) reaffirms the terms and conditions of its
                 sublicense and the terms and conditions of this Agreement
                 appearing in Articles II, V, VII, VIII, IX, X, XI, XII, XIII,
                 XIV and XV (hereafter referred to collectively as the
                 "Pertinent Terms"); (ii) agrees to abide by all of the terms
                 and conditions of its sublicense agreement and the requirements
                 of the Pertinent Terms of this Agreement; provided that in the
                 event of any inconsistency or other conflict between the
                 sublicense and the Pertinent Terms of this Agreement, the
                 Pertinent Terms of this Agreement shall control and to
                 discharge directly to CMCC (aa) all obligations of sublicensee
                 which sublicensee is obligated under the sublicense agreement
                 to discharge; and (bb) the obligations of LICENSEE arising
                 after the date of the new agreement between CMCC and the
                 sublicencee which LICENSEE would have been obligated to
                 discharge under the Pertinent Terms of this Agreement if this

                 shall have no obligations to the sublicensee other than its
                 obligations set forth in this Agreement with regard to
                 LICENSEE.

         2.6     All sublicenses granted by LICENSEE hereunder shall include a
                 requirement that the sublicensee use its good faith and
                 diligent efforts to bring the subject matter of the sublicense
                 into commercial use as quickly as is reasonably possible. In
                 addition, LICENSEE agrees that any sublicense granted by it
                 shall provide that the obligations to CMCC of Articles II, V,
                 VII, VIII, IX, X, XII, XIII, and XV of this Agreement shall be
                 binding upon the sublicensee as if it were a party to this
                 Agreement. LICENSEE further agrees to attach copies of these
                 Articles to sublicense agreements.

         2.7     LICENSEE agrees to forward to CMCC a copy of any and all fully
                 executed sublicense agreements, and further agrees to forward
                 to CMCC annually a copy of such reports received by LICENSEE
                 from its sublicensees during the preceding twelve (12) month
                 period under the sublicenses as shall be pertinent to a royalty
                 accounting under said sublicense agreements.

         2.8     LICENSEE shall not receive from sublicensees anything of value
                 in lieu of cash payments based upon payment obligations of any
                 sublicense under this Agreement, without the express prior
                 written permission of CMCC.

         2.9     The license granted hereunder shall not be construed to confer
                 any rights upon LICENSEE by implication, estoppel or otherwise
                 as to any technology not specifically set forth in Appendix A
                 hereof.


                          ARTICLE III -- DUE DILIGENCE


         3.1     LICENSEE shall use reasonable efforts to bring one or more
                 Licensed Products or Licensed Processes to market through a
                 thorough, vigorous and diligent program for exploitation of the
                 Patent Rights.

                 In connection with such reasonable efforts LICENSEE agrees to
                 satisfy the following due diligence milestones:

                 a. Commence human clinical trials by [*] if LICENSEE
                 determines that a 510K should be filed for the licensed
                 products or by [*] if

<PAGE>   7

                 LICENSEE determines that a PMA should be filed for the Licensed
                 Products.

                 b. If LICENSEE determines that a 510K should be filed with the
                 FDA then LICENSEE shall file the 510K by October 1997 or if
                 LICENSEE determines that a PMA should be filed for the Licensed
                 Products such PMA shall be filed by October 1998.

                 LICENSOR'S sole remedy for LICENSEE'S failure to use its
                 reasonable efforts under this Section 3.1 shall be termination
                 of this Agreement or conversion of the license to a
                 non-exclusive license.


                             ARTICLE IV -- ROYALTIES


         4.1     For the rights, privileges and license granted hereunder,
                 LICENSEE shall pay to CMCC in the manner hereinafter provided
                 to the end of the term of the Patent Rights or until this
                 Agreement shall be terminated as hereinafter provided:

                 a. A license issue fee of  [*]  which said license issue fee
                 shall be deemed earned and due:

                    (i) [*] immediately upon the execution of this Agreement
                    (ii) [*] one year from the effective signing date of
                    this Agreement
                    (iii) [*] two years from the effective signing date.

                 b. A royalty based on the Net Sales Price of the Licensed
                 Products or Licensed Processes, leased or sold by LICENSEE or a
                 joint venture in which LICENSEE is involved, which said royalty
                 shall be [*] while patent applications are still pending, and
                 [*] as soon as at least one patent in the Patent Rights has
                 been issued in the country where the royalty obligation is
                 accruing, whether or not other patent applications are still
                 pending in that country. If no patent issues in a specified
                 country, royalty shall be [*] in that country only.

                 C. Where sublicenses have been granted, LICENSEE shall pay to
                 CMCC [*] of any and all sublicensing fees, signing fees,
                 milestone payments and royalties received from sublicensees,
                 provided that CMCC shall receive royalties not less than [*] of
                 the Net Sales Price of the Licensed Products, or Licensed
                 Processes, leased or sold by LICENSEE's sublicensees.

                 d. In the event that LICENSEE participates in the formation of
                 a company to commercialize the Patent Rights, LICENSEE shall
                 cause such company to issue to CMCC common stock of such
                 company such that CMCC's percentage ownership interest therein
                 (on a fully diluted basis) shall not be less than [*] until
                 such time as   [*]   has been invested in such company (CMCC
                 to enjoy no anti-dilution protection thereafter).


         4.2     No multiple royalties shall be payable because any Licensed
                 Product, its manufacture, use, lease or sale are or shall be
                 covered by more than one Patent Rights Patent Application or
                 Patent Rights Patent licensed under this Agreement.

         4.3     Royalty payments shall be paid in United States dollars in
                 Boston, Massachusetts, or at such other place as CMCC may
                 reasonably designate consistent with the laws and regulations
                 controlling in any foreign country. If any currency conversion
                 shall be required in connection with the payment of royalties
                 hereunder, such conversion shall be made by using the exchange
                 rate prevailing at the Bank of Boston on the last business day
                 of the calendar quarterly reporting period to which such
                 royalty payments relate.


                        ARTICLE V -- REPORTS AND RECORDS


         5.1     LICENSEE shall keep full, true and accurate books of account
                 containing all particulars that may be necessary for the
                 purpose of showing the amounts payable to CMCC hereunder. Said
                 books of account shall be kept at LICENSEE's principal place of
                 business or the principal place of business of the appropriate
                 Division of LICENSEE to which this Agreement relates. Said
                 books and the supporting data shall be open at all reasonable
                 times for five (5) years following the end of the calendar year
                 to which they pertain, to the inspection of CMCC or its agents
                 for the purpose of verifying LICENSEE's royalty statement or
                 compliance in other respects with this Agreement.

         5.2     LICENSEE, within thirty (30) days after March 31, June 30,
                 September 30 and December 31, of each year, shall deliver to
                 CMCC true and accurate reports, giving such particulars of the
                 business conducted by



                                     - 8 -

                 (i) LICENSEE and (ii) and within forty-five (45) days of such
                 dates its sublicensees during the preceding three-month period
                 under this Agreement as shall be pertinent to a royalty
                 accounting hereunder. These shall include at least the
                 following:
                 a. Number of Licensed Products manufactured and sold.
                 b. Total collections for Licensed Products sold.
                 c. Accounting for all Licensed Products sold.
                 d. Deductions applicable as provided in Paragraph 1.6
                 e. Total royalties due.
                 f. Names and addresses of all sublicensees of LICENSEE.
                 g. Licensed Products manufactured and sold to the United States
                 Government. (No royalty obligations shall arise due to use by,
                 for or on behalf of the United States Government in view of the
                 royalty-free, nonexclusive license heretofore granted to the
                 United States Government.)

         5.3     With each such report submitted, LICENSEE shall pay to CMCC the
                 royalties due and payable under this Agreement. If no royalties
                 shall be due, LICENSEE shall so report.

         5.4     On or before the ninetieth (90th) day following the close of
                 LICENSEE's fiscal year, LICENSEE shall allow an independent
                 certified public accountant to review LICENSEE's financial
                 statements, for the preceding fiscal year including, at a
                 minimum, a Balance Sheet and an Operating Statement. In
                 addition, until LICENSEE brings one or more Licensed Products
                 or Licensed Processes to market, CMCC shall have the right to
                 send a representative, reasonably acceptable to LICENSEE, to
                 observe board meetings of the LICENSEE entity attempting to
                 bring Licensed Products or Licensed Processes to market.

         5.5     The royalty payments set forth in this Agreement shall, if
                 overdue, bear interest until payment at a per annum rate of [*]
                 above the prime rate in effect at the Bank of Boston on the due
                 date. The payment of such interest shall not foreclose CMCC
                 from exercising any other rights it may have as a consequence
                 of the lateness of any payment.

                        ARTICLE VI -- PATENT PROSECUTION


         6.1     The prosecution, filing and maintenance of all Patent Rights
                 Patents and Applications shall be the primary responsibility of
                 LICENSEE once the license has been executed; provided,
                 however, CMCC shall have reasonable opportunities to advise
                 LICENSEE and shall cooperate with LICENSEE in such prosecution,
                 filing and maintenance.

         6.2     Payment of all fees and costs relating to the filing,
                 prosecution, and maintenance of the Patent Rights shall be the
                 responsibility of LICENSEE, whether such fees and costs were
                 incurred before or after the date of this Agreement.

                           ARTICLE VII -- INFRINGEMENT


         7.1     LICENSEE shall inform CMCC promptly in writing of any alleged
                 infringement of the Patent Rights by a third party and of any
                 available evidence thereof.

         7.2     During the term of this Agreement, LICENSEE shall have the
                 right, but shall not be obligated, to prosecute at its own
                 expense any such infringements of the Patent Rights and, in
                 furtherance of such right, CMCC hereby agrees that LICENSEE may
                 join CMCC as a party plaintiff in any such suit, without
                 expense to LICENSEE. The total cost of any such infringement
                 action commenced or defended solely by LICENSEE shall be borne
                 by LICENSEE and LICENSEE shall keep any recovery or damages for
                 past infringement derived therefrom.

         7.3     If within six (6) months after having been notified of any
                 alleged infringement, LICENSEE shall have been unsuccessful in
                 persuading the alleged infringer to desist and shall not have
                 brought and shall not be diligently prosecuting an infringement
                 action, or if LICENSEE shall notify CMCC at any time prior
                 thereto of its intention not to bring suit against any alleged
                 infringer, then, and in those events only, CMCC shall have the
                 right, but shall not be obligated, to prosecute at its own
                 expense any infringement of the Patent Rights. No settlement,
                 consent judgment of other voluntary final disposition of the
                 suit may be entered into without the consent of the party not
                 bringing the suit, which consent shall not unreasonably be
                 withheld.

         7.4     In the event that LICENSEE shall undertake the enforcement
                 and/or defense of the Patent Rights by litigation, LICENSEE may
                 withhold up to fifty percent (50%) of the royalties otherwise
                 thereafter due CMCC hereunder and apply the same toward
                 reimbursement of its expenses, including reasonable attorneys,
                 fees, in connection therewith. Any recovery of damages by
                 LICENSEE for any such suit shall be applied first in
                 satisfaction of any unreimbursed expenses and legal fees of
                 LICENSEE relating to the suit, next toward reimbursement of
                 CMCC for any royalties past due or withheld and applied
                 pursuant to this Article VII, and to royalties due to CMCC for
                 infringing sales as if sales had been made by LICENSEE. The
                 balance remaining from any such recovery shall belong to
                 LICENSEE.

         7.5     In the event that a declaratory judgment action alleging
                 invalidity or non-infringement of any of the Patent Rights
                 shall be brought against LICENSEE, CMCC, at its option, shall
                 have the right, within thirty (30) days after commencement of
                 such action, to intervene and take over the sole defense of the
                 action at its own expense.

         7.6     In any infringement suit as either party may institute to
                 enforce the Patent Rights pursuant to this Agreement, the other
                 party hereto shall, at the request and the expense of the party
                 initiating such suit, cooperate in all respects and, to the
                 extent possible, have its employees testify when requested and
                 make available relevant records, papers, information, samples,
                 specimens, and the like.

         7.7     LICENSEE, during the period of this Agreement, shall have the
                 sole right in accordance with the terms and conditions herein
                 to sublicense any alleged infringer for the Field of Use for
                 future use of the Patent Rights.


                        ARTICLE VIII -- INDEMNIFICATION,
                        PRODUCT LIABILITY AND INSURANCE

         8.1.    Indemnification

         (a) LICENSEE shall indemnify, defend and hold harmless CMCC and its
         trustees, officers, medical and professional staff, employees, and
         agents and their respective successors, heirs and assigns (the
         "Indemnitees"), against any liability, damage, loss or expense
         (including



                                     - 11 -
<PAGE>   12

         reasonable attorney's fees and expenses of litigation) incurred by or
         imposed upon the Indemnitees or any one of them in connection with any
         claims, suits, actions, demands or judgments arising out of any theory
         of product liability (including, but not limited to, actions in the
         form of tort, warranty, or strict liability) concerning, any product,
         process or service made, used or sold pursuant to any right or license
         granted under this Agreement.

         (b) LICENSEE's indemnification under (a) above shall not apply to any
         liability, damage, loss or expense to the extent that it is directly
         attributable to the negligent activities, reckless misconduct or
         intentional misconduct of the Indemnitees.

         (c) LICENSEE agrees, at its own expense, to provide attorneys
         reasonably acceptable to CMCC to defend against any actions brought or
         filed against any party indemnified hereunder with respect to the
         subject of indemnity contained herein, whether or not such actions are
         rightfully brought.

         (d) This Section 8.1 shall survive expiration or termination of this
         Agreement.

         8.2. Insurance.

         (a) Beginning at the time as any such product, process or service is
         being commercially distributed or sold (other than for the purpose of
         obtaining regulatory approvals) by LICENSEE or by a sublicensee,
         affiliate or agent of LICENSEE, LICENSEE shall, at its sole cost and
         expense, procure and maintain comprehensive general liability insurance
         in amounts not less than [*] per incident and [*] annual aggregate and
         naming the Indemnitees as additional insureds. Such comprehensive
         general liability insurance shall provide (i) product liability
         coverage and (ii) broad form contractual liability coverage for
         LICENSEE's indemnification under Section 8.1 of this Agreement. If
         LICENSEE elects to self-insure all or part of the limits described
         above (including deductibles or retentions which are in excess of [*]
         annual aggregate) such self-insurance program must be acceptable to the
         CMCC and the Risk Management Foundation of the Harvard Medical
         Institutions, Inc. The minimum amount of insurance coverage required
         under this Section 8.2 shall not be construed to create a limit of
         LICENSEE's liability with respect to its indemnification under Section
         8.1 of this Agreement.

         (b) LICENSEE shall provide CMCC with written evidence of such insurance
         upon request of CMCC. LICENSEE shall


                                     - 12 -

<PAGE>   13

         provide CMCC with written notice at lease fifteen (15) days prior to
         the cancellation, non-renewal or material change in such insurance; if
         LICENSEE does not obtain replacement insurance providing comparable
         coverage within such fifteen (15) day period, CMCC shall have the right
         to terminate this Agreement effective at the end of such fifteen (15)
         day period without notice of any additional waiting periods.

         (c) LICENSEE shall maintain such comprehensive general liability
         insurance during (i) the period that any such product, process or
         service is being commercially distributed or sold (other than for the
         purpose of obtaining regulatory approvals) by LICENSEE or by a
         sublicensee, affiliate or agent of LICENSEE and (ii) a reasonable
         period after the period referred to in (c) (i) above which in no event
         shall be less than fifteen (15) years.

         (d) This ARTICLE 8.2 shall survive expiration or termination of this
         Agreement.


                          ARTICLE IX -- EXPORT CONTROLS


           It is understood that CMCC is subject to United States laws and
regulations controlling the export of technical data, computer software,
laboratory prototypes and other commodities (including the Arms Export Control
Act, as amended and the Export Administration Act of 1979), and that its
obligations hereunder are contingent on compliance with applicable United States
export laws and regulations. The transfer of certain technical data and
commodities may require a license from the cognizant agency of the United States
Government and/or written assurances by LICENSEE that LICENSEE shall not export
data or commodities to certain foreign countries without prior approval of such
agency. CMCC neither represents that a license shall not be required nor that,
if required, it shall be issued.


                          ARTICLE X -- NON-USE OF NAMES

           LICENSEE shall not use the names of the Children's Medical Center
corporation nor of any of its employees, nor any adaptation thereof, in any
advertising, promotional or sales literature without prior written consent
obtained from CMCC in each case except that LICENSEE may state that it is
licensed by CMCC under one or more of the patents and/or applications comprising
the Patent Rights, and LICENSEE may comply with disclosure requirements of all
applicable laws



                                     - 13 -

relating to its business, including United States and state security laws.


                            ARTICLE XI -- ASSIGNMENT


           This Agreement is not assignable by LICENSEE without the express
written consent of CMCC which shall not be unreasonably withheld; provided,
however, that LICENSEE shall have the right to assign this Agreement to a
Subsidiary without the consent of CMCC.


                           ARTICLE XII -- ARBITRATION


         12.1    Any and all claims, disputes or controversies arising under,
                 out of, or in connection with this Agreement, which have not
                 been resolved by good faith negotiations between the parties,
                 shall be resolved by final and binding arbitration in Boston,
                 Massachusetts, under patent arbitration rules of the American
                 Arbitration Association then obtaining. The arbitrators shall
                 have no power to add to, subtract from or modify any of the
                 terms or conditions of this Agreement. Any award rendered in
                 such arbitration may be enforced by either party in either the
                 courts of the Commonwealth of Massachusetts or in the United
                 States District Court for the District of Massachusetts, to
                 whose jurisdiction for such purposes CMCC and LICENSEE each
                 hereby irrevocably consents and submits.

         12.2    Notwithstanding the foregoing, nothing in this Article shall be
                 construed to waive any rights or timely performance of any
                 obligations existing under this Agreement.


                           ARTICLE XIII -- TERMINATION


         13.1    If LICENSEE shall cease to carry on its business, this
                 Agreement shall terminate upon notice by CMCC.

         13.2    Should LICENSEE fail to pay CMCC royalties due and payable
                 hereunder, CMCC shall have the right to terminate this
                 Agreement on thirty (30) days' notice, unless LICENSEE shall
                 pay CMCC within the thirty (30) day period, all such royalties
                 and interest due and payable. Upon the expiration of the thirty
                 (30) day period, if LICENSEE shall not have paid all such
                 royalties and interest due and




                                     - 14 -
<PAGE>   15


                 payable, the rights, privileges and license granted hereunder
                 shall terminate.

         13.3    Upon any material breach or default of this Agreement by
                 LICENSEE, other than those occurrences set out in Paragraphs
                 13.1 and 13.2 hereinabove, which shall always take precedence
                 in that order over any material breach or default referred to
                 in this Paragraph 13.3, CMCC shall have the right to terminate
                 this Agreement and the rights, privileges and license granted
                 hereunder by ninety (90) days' notice to LICENSEE. Such
                 termination shall become effective unless LICENSEE shall have
                 cured any such breach or default prior to the expiration of the
                 ninety (90) day period.

         13.4    LICENSEE shall have the right to terminate this Agreement at
                 any time on six (6) months' notice to CMCC, and upon payment of
                 all amounts due CMCC through the effective date of termination,
                 in no case prior to the end of the first year of full funding.

         13.5    Upon termination of this Agreement for any reason, nothing
                 herein shall be construed to release either party from any
                 obligation that matured prior to the effective date of such
                 termination. LICENSEE and any sublicensee thereof may, however,
                 after the effective date of such termination, sell all Licensed
                 Products, and complete Licensed Products in the process of
                 manufacture at the time of such termination and sell the same,
                 provided that LICENSEE shall pay to CMCC the royalties thereon
                 as required by Article IV of this Agreement and shall submit
                 the reports required by Article V hereof on the sales of
                 Licensed Products.



           ARTICLE XIV -- PAYMENTS, NOTICES, AND OTHER COMMUNICATIONS


           Any payment, notice or other communication pursuant to this Agreement
shall be sufficiently made or given on the date of the mailing if sent to such
party by certified first class mail, postage prepaid, addressed to it at its
address below or as it shall designate by written notice given to the other
party:

                     ARTICLE XV -- MISCELLANEOUS PROVISIONS


         15.1    This Agreement shall be construed, governed, interpreted and
                 applied in accordance with the laws of the Commonwealth of
                 Massachusetts, U.S.A., except that questions affecting the
                 construction and effect of any patent shall be determined by
                 the law of the country in which the patent was granted.

         15.2    The parties hereto acknowledge that this Agreement sets forth
                 the entire Agreement and understanding of the parties hereto as
                 to the subject matter hereof, and shall not be subject to any
                 change or modification except by the execution of a written
                 instrument subscribed to by the parties hereto.

         15.3    The provisions of this Agreement are severable, and in the
                 event that any provisions of this Agreement shall be determined
                 to be invalid or unenforceable under any controlling body of
                 law, such invalidity or unenforceability shall not in any way
                 affect the validity or enforceability of the remaining
                 provisions hereof.

         15.4    LICENSEE agrees to mark the Licensed Products sold in the
                 United States with all applicable United States patent numbers.
                 All Licensed Products shipped to or sold in other countries
                 shall be marked in such a manner as to conform with the patent
                 laws and practice of the country of manufacture or sale.

         15.5    The failure of either party to assert a right hereunder or to
                 insist upon compliance with any term or condition of this
                 Agreement shall not constitute a waiver of that right or excuse

                           EXCLUSIVE LICENSE AGREEMENT

                                       FOR

                          ELECTRODE ACUPUNCTURE SYSTEM

This license agreement ("Agreement") is effective this 30 day of June, 1996, by

California corporation, having its statewide administrative offices at 300
Lakeside Drive, 22nd Floor, Oakland, California 94612-3550 and UroSurge, Inc.
("Licensee"), a Delaware corporation, having a principal place of business at
2660 Crosspark Road, Coralville, Iowa 52241.


                                    Recitals

           Whereas, certain inventions, characterized as "Electrode Acupuncture
System" ("Invention"), useful for the control of incontinence, were made at the
University of California, San Francisco ("UCSF") by Dr. Gleason, et al. and are
claimed in Patent Rights defined below; 

           Whereas, the Licensee is a "small entity" as defined in 37 CFR
Section 1.9 and a "small-business concern" defined in 15 U.S.C. Section 632;

           Whereas, both parties recognize that royalties due under this
Agreement will be paid on pending patent applications and issued patents;

           Whereas, Licensee requested certain rights from The Regents to
commercialize the Invention; and





                                       1
<PAGE>   4

           Whereas, The Regents responded to the request of Licensee by granting
the following rights to Licensee so that the products and other benefits derived
from the Invention can be enjoyed by the general public.

                                   oo 0 oo - -



           The parties agree as follows:

                                  1 Definitions

As used in this Agreement, the following terms will have the meaning set forth
below:

1.1. "Patent Rights" means all U.S. patents and patent applications and foreign
patents and patent applications assigned to The Regents 14.3 including any
reissues, extensions, substitutions, continuations, divisions, and
continuation-in-part applications (only to the extent, however, that claims in
the continuation-in-part applications are entitled to the priority filing date
of the parent patent application) based on and including any subject matter
claimed in or covered by the following:

           1.1.1.     U.S. Patent Number 5,094,242, entitled "Implantable Nerve
                      Stimulation Device," issued on March 10, 1992 by Dr.
                      Gleason, et al. and assigned to The Regents; and

           1.1.2.     U.S. Patent Number 5,211,175, entitled "Method for
                      Implanting Electro-Acupuncture Needle," issued on May 18,
                      1993 by Dr. Gleason, et al. and assigned to The Regents

1.2. "Patent Products" means:

           1.2.1.     any kit, composition of matter, material, or product;

           1.2.2.     any kit, composition of matter, material, or product to be
                      used in a manner requiring the performance of the Patent
                      Method; or

           1.2.3.     any kit, composition of matter, material, or product
                      produced by the Patent Method;




                                       2

<PAGE>   5

to the extent that the manufacture, use, or sale of such kit, composition of
matter, material, or product, in a particular country, would be covered by or
infringe, but for the license granted to Licensee pursuant to this Agreement, an
unexpired claim of a patent or pending claim of a patent application were it
issued as a claim in a patent under Patent Rights in that country in which such
patent has issued or application is pending. 

1.3. "Patent Method" means any process or method covered by the claims of a
patent application or patent within Patent Rights or the use or practice of
which would constitute in a particular country, but for the license granted to
Licensee pursuant to this Agreement, an infringement of an unexpired claim of a
patent or pending claim of a patent application were it issued as a claim in a
patent within Patent Rights in that country in which the Patent Method is used
or practiced. 

1.4. "Net Sales" means the gross invoice prices from the sale of Patent Products
by Licensee, an Affiliate, a Joint Venture, or a Sublicensee to independent
third parties for cash or other forms of consideration in accordance with
generally accepted accounting principles limited to the following deductions (if
not already deducted from the gross invoice price and at rates customary within
the industry): (a) allowances (actually paid and limited to rejections, returns,
and prompt payment and volume discounts granted to customers of Patent Products,
whether in cash or Patent Products in lieu of cash); (b) freight, transport
packing, insurance charges associated with transportation; and (c) taxes,
tariff, or import/export duties based on sales when included in gross sales, but
not value-added taxes or taxes assessed on income derived from such sales. Where
Licensee distributes Patent Products for end use to itself, an Affiliate, a
Joint Venture, or a Sublicensee, then such distribution will be considered a
sale at list price normally charged to independent third parties, and The
Regents will be entitled to collect fees and royalties on such sale at the rate
set forth in Article 4. (Royalties).

1.5. "Affiliate(s)" of Licensee means any entity which, directly or indirectly,
controls Licensee, is controlled by Licensee, or is under common control with
Licensee ("control" for these purposes being defined as the actual, present
capacity to elect a majority of the directors of such affiliate, or if not, the
capacity to elect the members that control fifty percent (50%) of the
outstanding stock or other voting rights entitled to elect directors) provided,
however, that in any country where the local law will not permit foreign equity
participation of a majority, then an "Affiliate" will include any company in
which Licensee will own or control, directly or indirectly, the maximum
percentage of such outstanding stock or voting rights permitted by local law.
Each reference to Licensee herein will be meant to include its Affiliates. 

1.6. "Joint Venture" means any separate entity established pursuant to an
agreement between a third party and Licensee to constitute a vehicle for a joint
venture, in which the separate entity manufactures, uses, purchases, sells, or
acquires Patent Products from Licensee. Each reference to Licensee herein will
be meant to include its Joint Venture.

1.7. "Sublicensee" means any non-Affiliate third party that is granted by
Licensee the right to make, have made, use, or sell any Patent Products, or use
the Patent Method.

                                    2. Grant

2.1. Subject to the limitations set forth in this Agreement, The Regents hereby
grants to Licensee exclusive licenses under Patent Rights to make, have made,
use, sell, offer for sale, and import Patent Products and to practice the Patent
Method.

2.2. The manufacture of Patent Products and the practice of the Patent Method
will be subject to applicable government importation laws and regulations of a

                                  4. Royalties



4.1. As further consideration for all the rights and licenses granted to
Licensee, Licensee will also pay to The Regents an earned royalty according to
the following:

           4.1.1.     a royalty rate of [*] based on the Net Sales of Patent
                      Products sold by Licensee; and

           4.1.2.     an amount equal to [*] of all consideration, fees, and
                      royalties received by Licensee from its Sublicensees with
                      respect to Patent Products and Patent Methods. Not
                      withstanding the above, The Regents will not be entitled
                      to any portion of any amounts received by Licensee from
                      Sublicensee with respect to: (i) the purchase of equity in
                      Licensee at or below [*] of the fair market value of such
                      equity, (ii) debt financing, (iii) research funding, and
                      (iv) reimbursement of patent filing, prosecution, and
                      maintenance expenses. The Regents will be entitled to
                      receive [*] of any amounts received by Licensee from
                      Sublicense with respect to the purchase of equity in
                      Licensee in an amount above [*] of the fair market value
                      of such equity. Any consideration received by Licensee
                      from its Sublicensees will be converted into a U.S. dollar
                      cash equivalent for purposes of computing the royalties
                      due The Regents under this Subparagraph.

           4.1.3.     For the avoidance of doubt, it is understood and agreed
                      that in the event that Licensee assigns its rights under
                      this Agreement in connection with the sale or transfer of
                      all or substantially all of the assets of Licensee
                      relating to the subject matter of this Agreement pursuant
                      to Section 19.1 herein, The Regents shall not be entitled
                      to any portion of any consideration received by Licensee
                      in connection with such sale or transfer.

4.2. Paragraphs 1.1, 1.2, and 1.3 define Patent Rights, Patent Products, and
Patent Method so that royalties will be payable on Patent Products and Patent
Method covered by both pending patent applications and issued patents. Earned
royalties will accrue in each country for the duration of Patent Rights in that
country and will be payable to The Regents when Patent Products are invoiced, or
if not invoiced, when delivered to a third party or to itself, an Affiliate, or
Sublicensee in the case where such delivery of the



                                        7

<PAGE>   10

Patent Products to Licensee, an Affiliate, or Sublicensee is intended for end
use for purposes other than clinical trials. 

4.3. In the event that no patent issues in a particular country under Patent
Rights within five (5) years (except for Japan which shall be eight (8) years)
from the effective date recited on page one of this Agreement, then earned
royalties and minimum annual royalties (set forth in Paragraphs 4.1.1 and 4.1.2
above due The Regents in connection with the sale of Patent Products in such
country shall be suspended from that date. At the time a patent under Patent
Rights does issue in a particular country, Licensee's obligations to pay earned
royalties (in accordance with Paragraphs 4.1.1 and 4.1.2 on Patent Products)
shall resume with respect to sales of Patent Products after such date only in
connection with the Patent Products that would, but for the licenses granted
herein, infringe a valid claim of such issued, unexpired patent in such country,
and payment of such royalties and minimum annual royalties shall continue for
the life of this Agreement, subject to the provisions of Paragraphs 4.1.1,
4.10, and 8.2.

4.4. No more than one royalty payment will be due to The Regents with respect to
a sale of a particular Patent Products. No multiple royalties will be payable
whether or not any Patent Products, or their manufacture, use, or sale is
covered by more than one claim within the Patent Rights. 

4.5. Royalties from Licensee and the payment of fees, royalties, and other
consideration by Licensee from its Sublicensees accruing to The Regents will be
paid to The Regents quarterly on or before the following dates of each calendar
year: 

           February 28 for the calendar quarter ending December 31

           May 31 for the calendar quarter ending March 31

           August 31 for the calendar quarter ending June 30

           November 30 for the calendar quarter ending September 30





                                        8



<PAGE>   11

Each such payment will be for royalties from Licensees and the payment of fees,
royalties and other consideration from Sublicensees which accrued up to the most
recently completed calendar quarter of Licensee or its Sublicensees.

4.6. Beginning in the year 1998, or in the year of first commercial sale,
whichever is earlier, Licensee will pay to The Regents a minimum annual royalty
in the amounts and at the times set forth below:


<TABLE>
<S>                                                  <C>    
                           1998 -                    [*]
                           1999 -                    [*]
                           2000 -                    [*]
</TABLE>

Licensee will pay a minimum annual royalty of $50,000 in each succeeding
calendar year after the year 2000 for the life of this Agreement. This minimum
annual royalty will be paid to The Regents by February 28 of each year and will
be credited against the earned royalty due and owing for the calendar year in
which the minimum payment was made.

4.7. All monies due The Regents will be payable in United States funds
collectible at par in San Francisco, California. When Patent Products are sold
for monies other than United States dollars, the earned royalties will first be
determined in the foreign currency of the country in which such Patent Products
were sold and then converted into equivalent United States funds. The exchange
rate will be that rate quoted in the Wall Street Journal on the last business
day of the calendar quarter.

4.8. Earned royalties on sales of Patent Products occurring in any country
outside the United States will not be reduced by any taxes, fees, or other
charges imposed by the government of such country except those taxes, fees, and
charges allowed under the provisions of Paragraph 1.4 (Net Sales). Licensee will
also be responsible for all bank transfer charges.

4.9. Notwithstanding the provisions of Article 26. (Force Majeure), if at any
time legal restrictions prevent prompt remittance of part or all royalties owed
to The Regents by



                                        9


[*] Confidential treatment requested.
<PAGE>   12

Licensee with respect to any country where Patent Products are sold or
distributed, Licensee will convert the amount owed to The Regents into United
States funds and will pay The Regents directly from another source of funds for
the amount impounded.

4.10. In the event that any patent or any claim thereof included within the
Patent Rights is held invalid in a final decision by a court of competent
jurisdiction and last resort and from which no appeal has or can be taken, all
obligation to pay royalties based on such patent or claim or any claim
patentably indistinct therefrom will cease as of the date of such final
decision. Licensee will not, however, be relieved from paying any royalties that
accrued before such decision or that are based on another patent or claim that
has not expired or that is not involved in such decision.

                                5. Due Diligence

5.1. Licensee, upon execution of this Agreement, will diligently proceed with
the development, manufacture, and sale of Patent Products and will earnestly and
diligently market Patent Products after execution of this Agreement and in
quantities sufficient to meet the market demands therefor.

5.2. Licensee will be entitled to exercise prudent and reasonable business
judgment in the manner in which it meets its due diligence obligations
hereunder. In no case, however, will Licensee be relieved of its obligations to
meet the due diligence provisions of this Article 5. (Due Diligence).

5.3. Licensee will obtain all necessary governmental approvals in each country
in which Patent Products are manufactured, used, and sold.

5.4. If Licensee is unable to perform the following:

<PAGE>   13

           5.4.1.     submit to the United States Food and Drug Administration
                      ("FDA") an application for a 510(k) to market Patent
                      Products in the United States on or before [*]; and

           5.4.2.     introduce Patent Products to the market in the United
                      States on or before [*]; or

           5.4.3.     file an IDE for Patent Products by [*]; and

           5.4.4.     enter phase II/III clinical trials for Patent Products in
                      the United States on or before [*]; and

           5.4.5.     submit to the United States Food and Drug Administration
                      ("FDA") an application for a Pre-Market Approval (PMA)
                      to market Patent Products in the United States on or
                      before [*]; and

           5.4.6.     introduce Patent Products to the market in the United
                      States within six (6) months after receiving marketing
                      approval from the United States FDA for such Patent
                      Products and reasonably fill the market demand for a
                      Patent Products following commencement of marketing at any
                      time during the exclusive period of this Agreement;

then The Regents will have the right and option to either terminate this
Agreement or reduce the exclusive licenses granted to Licensee to non-exclusive
licenses in accordance with Paragraph 5.5 hereof. The exercise of this right and
option by The Regents supersedes the rights granted in Article 2. (Grant). 

5.5. To exercise either the right to terminate this Agreement or reduce the
exclusive licenses granted to Licensee to non-exclusive licenses for lack of
diligence required in this Article 5. (Due Diligence), The Regents will give
Licensee written notice of the deficiency. Licensee thereafter has 60 days to
cure the deficiency. Licensee will have the right to present written tangible
evidence that it has made good faith efforts to diligently meet and cure any
milestone; and The Regents will take into consideration the evidence provided by
Licensee. However, if The Regents has not received written tangible evidence
satisfactory to The Regents that the deficiency has been cured by the end of the
60-day period or if The Regents is not satisfied with the evidence provided to

6.1. Beginning August 31, 1996 and semi-annually thereafter, Licensee will
submit to The Regents a progress report covering activities by Licensee related
to the development and testing of all Patent Products and obtaining governmental
approvals necessary for marketing. These progress reports will be provided to
The Regents to cover the progress of the research and development of the Patent
Products until their first commercial sale in the United States.

6.2. The progress reports submitted under Paragraph 6.1 will include, but not be
limited to, the following topics so that The Regents may be able to determine
the progress of the development of Patent Products and may also be able to
determine whether or not Licensee has met its diligence obligations set forth in
Article 5. (Due Diligence) above:

          -    summary of work completed key scientific discoveries summary of
          -    work in progress current schedule of events or milestones
          -    anticipated market introduction date of Patent Products,
          -    activities of Sublicensees, if any.

6.3. Licensee will also report to The Regents in its immediately subsequent
progress and royalty report the date of first commercial sale of Patent Products
in each country. After the first commercial sale of Patent Products, Licensee
will provide The Regents with quarterly royalty reports to The Regents on or
before each February 28, May 31,



                                       12

most recently completed calendar quarter of Licensee (October through December,
January through March, April through June, and July through September) and will
show:

          6.3.1. the gross sales and Net Sales of Patent Products sold by
               Licensee and reported to Licensee as sold by its Sublicensees
               during the most recently completed calendar quarter;

          6.3.2. the number of Patent Products sold or distributed by Licensee
               and reported to Licensee as sold or distributed by its
               Sublicensees;

          6.3.3. the royalties from Licensee, and the payment of fees, royalties
               and other consideration from Sublicensees in U.S. dollars,
               payable hereunder with respect to Net Sales; and

          6.3.4. the exchange rates used, if any.

6.4. If no sales of Patent Products have been made during any reporting period
after the first commercial sale of Patent Products, then a statement to this
effect is required.


                              7. Books and Records

7.1. Licensee will keep books and records accurately showing all Patent Products
manufactured, used, and/or sold under the terms of this Agreement. Such books
and records will be preserved for at least four years after the date of the
royalty payment to which they pertain and will be open to inspection by an
independent certified accountant retained by The Regents at reasonable times and
during normal business hours to determine the accuracy of the books and records
and to determine compliance by Licensee with the terms of this Agreement. Such
independent certified public accountant will be bound to hold all information in
confidence except as necessary to communicate to The Regents any non-compliance
of Licensee with respect to this Agreement.




                                       13
<PAGE>   16

7.2. The fees and expenses of The Regents accountant performing such an
examination will be borne by The Regents. If an error in royalties of more than
five percent (5%) of the total royalties due for any year is discovered, then
the fees and expenses of such accountant will be borne by Licensee.

                            8. Life of the Agreement

8.1. Unless otherwise terminated by operation of law or by acts of the parties
in accordance with the terms of this Agreement, this Agreement will be in force
from the effective date recited on page one and will remain in effect for the
life of the last-to-expire patent licensed under this Agreement, or until the
last patent application licensed under this Agreement is abandoned.

8.2. Any termination of this Agreement will not affect the rights and
obligations set forth in the following Articles:

                          9. Termination by The Regents

9.1.    If Licensee should violate or fail to perform any material term or
covenant of this Agreement, then The Regents may give written notice of such
default ("Notice of Default") to Licensee. If Licensee should fail to repair
such default within 60 days after the date of such notice takes effect, The
Regents will have the right to terminate this Agreement and the licenses herein
by a second written notice ("Notice of Termination") to Licensee. If a Notice of
Termination is sent to Licensee, this Agreement will automatically terminate on
the date such notice takes effect. Such termination will not relieve Licensee of
its obligation to pay any royalty or license fees owing at the time of such
termination and will not impair any accrued right of The Regents. These notices

Regents hereunder prior to the time such termination becomes effective, and such
termination will not affect in any manner any rights of The Regents arising
under this Agreement prior to such termination.

                enforceability, or scope of any Patent Rights; or

        13.4.2. a warranty or representation that anything made, used, sold, or
                otherwise disposed of under any license granted in this
                Agreement is or will be free from infringement of patents of
                third parties; or

        13.4.3. an obligation to bring or prosecute actions or suits against
                third parties for patent infringement except as provided in
                Article 16. (Patent Infringement); or


                                       17
<PAGE>   20
        13.4.4. conferring by implication, estoppel, or otherwise any license or
                rights under any patents of The Regents other than Patent Rights
                as defined herein, regardless of whether such patents are
                dominant or subordinate to Patent Rights; or

        13.4.5. an obligation to furnish any know-how not provided in Patent
                Rights.

                     14. Patent Prosecution and Maintenance

14.1.   The Regents will diligently prosecute and maintain the United States and
foreign patent applications and patents comprising Patent Rights using counsel
of its choice that is reasonably acceptable to Licensee, provided, however, that
if Licensee rejects The Regents' choice of new counsel three times consequently
(i.e. three different new attorneys), then The Regents will be free, in its sole
discretion, to choose an attorney of its choice. The Regents will promptly
instruct its outside counsel to provide Licensee with copies of all documents
received from every patent office, so that Licensee may be currently and
promptly informed and apprised of the continuing prosecution, and The Regents
will instruct its outside counsel to provide Licensee with copies of proposed
drafts of all documents to be filed with any patent office so that Licensee may
comment upon such documentation sufficiently in advance of any initial deadline
for filing a response, provided, however, that if Licensee has not commented
upon such documentation prior to the initial deadline for filing a response with
the relevant government patent office or The Regents must act to preserve Patent
Rights, The Regents will be free to respond appropriately without consideration
of comments by Licensee, if any. Both parties hereto will keep this
documentation in confidence in accordance with the provisions of Article 27.
(Confidentiality) herein. Counsel for The Regents will take instructions only
from The Regents.

14.2.   The Regents will use all reasonable efforts to amend any patent
application to include claims requested by Licensee and required to protect the
Patent Products contemplated to be sold or Patent Method to be practiced under
this Agreement.


                                       18
<PAGE>   21
14.3.   The Regents will, at the request of Licensee, file, prosecute, and
maintain patent applications and patents covered by Patent Rights in foreign
countries if available. The Regents will have the right to file patent
applications at its own expense in any country Licensee has not included in its
list of desired countries, and such applications and resultant patents, if any,
will not be included in the licenses granted under this Agreement. 

14.4.   All past, present and future costs of preparing, filing, prosecuting and
maintaining all United States and foreign patent applications and all costs and
fees relating to the preparation and filing of patents covered by Patent Rights
in Paragraph 1.1 will be borne by Licensee. This includes patent preparation and
prosecution costs for the Invention incurred by The Regents prior to the
execution of this Agreement. Such costs will be due upon execution of this
Agreement and will be payable at the time that the license issue fee is payable.
The costs of all interferences and oppositions will be considered prosecution
expenses and also will be borne by Licensee. Licensee will reimburse The Regents
for all costs and charges within 30 days following receipt of an itemized
invoice from The Regents for same. 

14.5.   The obligation of Licensee to underwrite and to pay patent preparation,
filing, prosecution, maintenance, and related costs will continue for costs
incurred until three months after receipt by either party of a Notice of
Termination. Licensee will reimburse The Regents for all patent costs incurred
during the term of the Agreement and for three months thereafter whether or not
invoices for such costs are received during the three-month period after receipt
of a Notice of Termination. Licensee may with respect to any particular patent
application or patent terminate its obligations with the patent application or
patent in any or all designated countries upon three months written notice to
The Regents. The Regents may continue prosecution and/or maintenance of such
application(s) or patent(s) at its sole discretion and expense, provided,
however, that Licensee will have no further right or licenses thereunder.


                                       19
<PAGE>   22
14.6.   Licensee will notify The Regents of any change of its status as a small
entity (as defined by the United States Patent and Trademark Office) and of the
first sublicense granted to an entity that does not qualify as a small entity as
defined therein. 

                               15. Patent Marking

15.1.   Licensee will mark all Patent Products made, used, or sold under the
terms of this Agreement, or their containers, in accordance with the applicable
patent marking laws.

                             16. Patent Infringement

16.1.   In the event that Licensee or the licensing associate employed by The
Regents who is responsible for administering this Agreement or Resident Counsel
of the Office of Technology Transfer learn of the substantial infringement of
any patent licensed under this Agreement, and to the extent it is contractually
able to, such party will call the attention of the other party thereto in
writing and will provide The Regents with reasonable evidence of such
infringement. Both parties to this Agreement acknowledge that during the period
and in a jurisdiction where Licensee has exclusive rights under this Agreement,
neither will notify a third party of the infringement of any of Patent Rights
without first obtaining consent of the other party, which consent will not be
unreasonably withheld. Both parties will use their best efforts in cooperation
with each other to terminate such infringement without litigation.

16.2.   Licensee may request that The Regents take legal action against the
infringement of Patent Rights. Such request must be made in writing and must
include reasonable evidence of such infringement and damages to Licensee. If the
infringing activity has not been abated within 90 days following the effective
date of such request, The Regents will have the right to elect to:


                                       20
<PAGE>   23
        16.2.1. commence suit on its own account; or

        16.2.2. refuse to participate in such suit

and The Regents will give notice of its election in writing to Licensee by the
end of the 100th day after receiving notice of such request from Licensee.
Licensee may thereafter bring suit for patent infringement if and only if The
Regents elects not to commence suit and if the infringement occurred during the
period and in a jurisdiction where Licensee had exclusive rights under this
Agreement. However, in the event Licensee elects to bring suit in accordance
with this paragraph, The Regents may thereafter join such suit at its own
expense.

16.3.   Such legal action as is decided upon will be at the expense of the party
on account of whom suit is brought and all recoveries recovered thereby will
belong to such party, provided, however, that legal action brought jointly by
The Regents and Licensee and participated in by both will be at the joint
expense of the parties and all recoveries will be allocated in the following
order: a) to each party reimbursement in equal amounts of the attorney's costs,
fees, and other related expenses to the extent each party paid for such costs,
fees, and expenses until all such costs, fees, and expenses are consumed for
each party; and b) any remaining amount to be divided among the parties in the
following manner: 1) [*] for Licensee and [*] for The Regents of any recoveries
based on lost profits or other theories; and 2) [*] for Licensee and [*] for The
Regents of any recoveries based on statutory enhanced damages.

16.4.   Each party will cooperate with the other in litigation proceedings
instituted hereunder but at the expense of the party on account of whom suit is
brought. Such litigation will be controlled by the party bringing the suit,
except that The Regents may be represented by counsel of its choice in any suit
brought by Licensee.

        (a)     Provide for 30 day advance written notice to The Regents of any
                modification;

17.3.   The Regents will promptly notify Licensee in writing of any claim or

The Regents informed on a current basis of its defense of any claims pursuant to
this Article 17. (Indemnification).

17.4. Licensee will have the right to control the defense and settlement of any
such claim or suit except Licensee shall not enter into any settlement which (i)
makes any admission of wrongdoing on the part of The Regents; or (ii) admits
that any Patent Rights of The Regents are invalid, unenforceable, or not
infringed, without prior written consent of The Regents.

all the assets of Licensee relating to the subject matter of this Agreement,

20.1.   In the event royalty payments or fees or patent prosecution costs are
not received by The Regents when due, Licensee will pay to The Regents interest
charges at a rate of ten percent (10%) simple interest per annum. Such interest

21.1.   It is agreed that no waiver by either party hereto of any breach or

laws of the country of such patent or patent application.

otherwise similarly appropriate by the disclosing party, or if the Proprietary

disclosing party, and delivered to the receiving party within 30 days after the
oral disclosure as a record of the disclosure and the confidential nature
thereof. Notwithstanding the foregoing, Licensee and The Regents may use and
disclose Proprietary Information to their employees, agents, consultants,
contractors, and, in the case of Licensee, its Sublicensees, provided that any
such parties are bound by a like duty of confidentiality.

27.3.   Nothing contained herein will in any way restrict or impair the right of
Licensee or The Regents to use, disclose, or otherwise deal with any Proprietary
Information:

                known to it;

        27.3.2. that is now, or becomes in the future, public knowledge other
                than through acts or omissions of recipient;

        27.3.3. that is lawfully obtained without restrictions by recipient from
                sources independent of the disclosing party;

        27.3.4. that is required to be disclosed to a governmental entity or
                agency in connection with seeking any governmental or regulatory
                approval, or


                                       27
<PAGE>   30
                pursuant to the lawful requirement or request of a governmental
                entity or agency;

        27.3.5. that is furnished to a third party by the recipient with similar
                confidentiality restrictions imposed on such third party, as
                evidenced in writing; or

        27.3.6. that The Regents is required to disclose pursuant to the
                California Public Records Act or other applicable law.

27.4.   Upon termination of this Agreement, Licensee and The Regents will

the other in its possession within 15 days following the effective date of

been returned or destroyed. Each party may, however, retain one copy of
Proprietary Information for archival purposes in nonworking files. 

                                28. Miscellaneous

creditors, or the Business applies for or consents to the appointment of a
trustee or receiver for the Business or for the major part of its property; or
if a trustee or receiver is appointed for the Business or for all or a
substantial part of the assets of the Business and the order of such appointment
is not discharged, vacated or stayed within sixty (60) days after such

                  by the Business.

      10.4  FAILURE TO MEET JOB ATTAINMENT OBLIGATION. If the Business is
determined by the Department to be in default of the Loan Agreement due to
meeting less than one hundred percent (100%) of its Job Attainment and Wage
Obligation, the Department may require full Loan repayment as described in
section 10.2 above or, at its discretion, the Department may permit repayment of
Loan proceeds using the following criteria:

            (a)   FORGIVABLE LOANS. If the CEBA award is a Forgivable Loan,
interest buy-down or interest subsidy, the Department may require repayment of
Loan proceeds as follows:

            A five-year $35,000 forgivable loan. There will be no principal or
interest payments or accruals for years one and two. At the project completion
date, if the Business has fulfilled at least 50% of its job creation/retention
(if applicable) and wage obligation, $1,250 will be forgiven for each new FTE
job created/retained (if applicable) and maintained for at least ninety days
past the project completion date. Any balance (shortfall) will be amortized over
the remaining three years of the contract period (beginning at the project
completion date) at six (6%) percent interest per annum with equal annual
payments. And, interest will be charged at six (6%) percent per annum from the
date of the first CEBA disbursement on the shortfall amount with that amount
accrued as of the project completion date being due and payable immediately.
And, further, the Department will at the end of the agreement expiration date
determine the number of full-time equivalent jobs, and, if that number is less
than the job attainment obligation in 7.1 and 7.2 of this agreement, the
Business will reimburse funds to the Department on the cost-per-job basis set
out above. If the Business has failed to fulfill at least 50% of its job
creation/retention (if applicable) and wage obligation, 100% of the CEBA award
will be repaid as the shortfall amount under the above-described terms and
conditions.


<PAGE>   14

CEBA 98-CEBA-03 
PAGE 14


            (b)   CONVENTIONAL LOANS. If the Business received a Loan at a rate
that is below the annual interest rate for non-compliance as set periodically by
the IDED Board, the remaining principal amount of the Loan may be prorated
between the percentage of FTE Jobs created/retained (if applicable) at the
Project Wage Threshold and the percentage of the shortfall. The shortfall
principal portion may be amortized over the remaining term of the Loan,
beginning at the Project Completion Date, at an annual interest rate as
determined periodically by the IDED Board. Interest will be charged beginning
from the date Loan proceeds were disbursed to the Community on behalf of the
Business; interest accrued from this date will be due immediately. The pro rata
portion of the Loan associated with the percentage of FTE Jobs created will be
amortized at the original rate and term.

        1. Inspection Rights. The Company shall permit each Investor, or any
authorized representative thereof, to visit and inspect the properties of the
Company, including its corporate and financial records, and to discuss its
business and finances with officers of the Company, during normal business hours

rights granted to Investors under this Section 1 shall terminate upon the
closing of the sale of shares of Common Stock in an underwritten public offering
pursuant to an effective registration statement under the Securities Act of
1933, as amended, which results in the automatic conversion of all outstanding
Preferred Stock into Common Stock in accordance with the Company's Certificate
of Incorporation (a "Qualified Public Offering").

        2.     Financial Statements and Other Information.

               2.1 Delivery to Investors. The Company will deliver to each
Investor:

                      (a) within 90 days after the end of each fiscal year of

and audited statements of income and of cash flows of the Company for such year,

after commencement of each new fiscal year, a business plan and projected
financial statements for such fiscal year; and

                      (b) with reasonable promptness, such other notices,
information and data with respect to the Company as the Company delivers to the
holders of its Common Stock, and such other information and data as such Major
Investor may from time to time reasonably request.

               2.3 Consolidated Basis. The foregoing financial statements shall
be prepared on a consolidated basis if the Company then has any subsidiaries.

               2.4 Definition of Major Investor. For purposes of this Agreement,
the term "Major Investor" shall mean an Investor holding not less than one
hundred thousand (100,000) shares of Preferred Stock, so long as such Investor
continues to own not less than one hundred thousand (100,000) shares of
Preferred Stock. For purposes of determining the number of shares held by an
Investor, (i) the foregoing number shall be adjusted for any stock splits, stock
dividends, recapitalizations or similar events, (ii) shares of Preferred Stock
shall include shares which have been converted into Common Stock so long as such
Common Stock is held by such Investor, and (iii) with respect to Investors that
are corporations or partnerships, shares of Preferred Stock shall include shares
distributed to and held by their respective shareholders and partners.

               2.5 Termination of Rights. The obligations of the Company under
this Section 2 shall terminate upon the closing of a Qualified Public Offering.

        3.     Right of First Refusal.

               3.1 Grant of Right of First Refusal. The Company hereby grants to
each Investor a right of first refusal to purchase all or part of its or his pro
rata share of any New Securities (as defined below) which the Company may, from
time to time, propose to sell and issue following the date of this Agreement,
subject to the terms and conditions set forth below. An Investor's pro rata
share, for purposes of this Section 3, shall equal a fraction, the numerator of
which is the number of shares of Common Stock then held by such Investor or
issuable upon conversion or exercise of any shares of Preferred Stock or other
convertible securities, options, rights or warrants then held by such Investor,
and the denominator of which is the total number of shares of Common Stock then
outstanding plus the number of shares of Common Stock issuable upon conversion
or exercise of then outstanding Preferred Stock or other convertible securities,
options, rights or warrants.

               3.2 Definition of New Securities. "New Securities" shall mean any
capital stock of the Company whether now authorized or not, and rights, options
or warrants to purchase capital stock, and securities of any type whatsoever
which are, or may become, convertible into capital stock; provided, however,
that the term "New Securities" does not include (i) the shares of Series C
Preferred Stock issued or issuable pursuant to the terms of the Stock Purchase
Agreement; (ii) the shares of Common Stock issued or issuable upon conversion of
shares of Preferred Stock; (iii) securities offered to the public pursuant to a
Registration Statement (as defined in Section 4.1); (iv) securities issued for



<PAGE>   3


the acquisition of another corporation by the Company by merger, purchase of
substantially all the assets of such corporation or another reorganization
resulting in the ownership by the Company of not less than a majority of the
voting power of such corporation; (v) not more than 1,010,000 shares of Common
Stock (such number being subject to adjustment for any stock dividend, stock
split, subdivision, combination or other recapitalization of the Common Stock of
the Company) issued to directors or employees of or consultants to the Company
pursuant to a stock option plan, employee stock purchase plan, restricted stock
plan or other employee stock plan or agreement or otherwise (and, in the case of
rights, options or warrants, the Common Stock issuable upon exercise thereof);
or (vi) securities issued as a result of any stock split, stock dividend or
reclassification of Common Stock, distributable on a pro rata basis to all
holders of Common Stock.

               3.3 Procedure. In the event the Company intends to issue New
Securities, it shall give each Investor written notice of such intention,
describing the type of New Securities to be issued, the price thereof and the
general terms upon which the Company proposes to effect such issuance. Each
Investor shall have 20 days from the date of any such notice to agree to
purchase all or part of its or his pro rata share of such New Securities for the
price and upon the general terms and conditions specified in the Company's
notice by giving written notice to the Company stating the quantity of New
Securities to be so purchased. Each Investor shall have a right of overallotment
such that if any Investor fails to exercise his or its right hereunder to
purchase his or its total pro rata portion of New Securities, the other
Investors may purchase such portion on a pro rata basis, by giving written
notice to the Company within five days from the date that the Company provides
written notice to the other Investors of the amount of New Securities with
respect to which such nonpurchasing Investor has failed to exercise its or his
right hereunder.

               3.4 Failure to Exercise Right of First Refusal. In the event any
Investor or Investors fail to exercise the foregoing right of first refusal with
respect to any New Securities within such 20-day period (or the additional
five-day period provided for overallotments), the Company may within 120 days
thereafter sell any or all of such New Securities not agreed to be purchased by
the Investors, at a price and upon general terms no more favorable to the
purchasers thereof than specified in the notice given to each Investor pursuant
to Section 3.3 above. In the event the Company has not sold such New Securities
within such 120-day period, the Company shall not thereafter issue or sell any
New Securities without first offering such New Securities to the Investors in
the manner provided above.

               3.5 Definition of Investor. For purposes of this Section 3,
"Investor" shall include the general partners, officers or other affiliates of
an Investor, and an Investor may apportion its pro rata share among itself and
such general partners, officers and other affiliates in such proportions as it
deems appropriate.

               3.6 Termination of Rights. All rights granted to Investors under
this Section 3 shall terminate on the closing of a Qualified Public Offering.

                      "Registration Statement" means a registration statement
filed by the Company with the Commission for a public offering and sale of
securities of the Company (other than a registration statement on Form S-8 or
Form S-4, or their successors, or any other form for a limited purpose, or any
registration statement covering only securities proposed to be issued in
exchange for securities or assets of another corporation).

                      "Registration Expenses" means the expenses described in
Section 4.5.

                      "Registrable Shares" means (i) the shares of the Company's
Common Stock issued or issuable upon conversion of shares of Preferred Stock,
and (ii) any other shares of Common Stock of the Company issued in respect of
such shares (because of stock splits, stock dividends, reclassifications,
recapitalizations, or similar events); provided, however, that shares of Common
Stock which are Registrable Shares shall cease to be Registrable Shares upon any
sale of such shares pursuant to a Registration Statement or Rule 144 under the
Securities Act or any sale in any manner to a person or entity which, by virtue
of Section 5 of this Agreement, is not entitled to the rights provided by this
Section 4. Wherever reference is made in this Agreement to a request or consent
of holders of a certain percentage of Registrable Shares, the determination of
such percentage shall include shares of Common Stock issuable upon conversion of
shares of Preferred Stock or Preferred Stock previously issued even if such
conversion has not been effected.

                      "Securities Act" means the Securities Act of 1933, as

               4.2    Required Registrations.

                      (a) At any time after the earlier of December 31, 1998 or
the closing of the Company's first underwritten public offering of shares of
Common Stock pursuant to a Registration Statement, an Investor or Investors
holding in the aggregate at least 35% of the Registrable Shares may request, in
writing, that the Company effect the registration on Form S-1 or Form S-2 (or
any successor form) of Registrable Shares owned by such Investor or Investors
having an aggregate offering price of at least $2,000,000 (based on the then
current market price or fair value). If the holders initiating the registration
intend to distribute the Registrable Shares by means of an underwriting, they
shall so advise the Company in their request. In the event such registration is
underwritten, the right of other Investors to participate shall be conditioned
on such Investors' participation in such underwriting. Upon receipt of any such
request, the Company shall promptly give written notice of such proposed
registration to all Investors. Such Investors shall have the right, by giving
written notice to the Company within 30 days after the Company provides its
notice, to elect to have included in such registration such of their Registrable
Shares as such Investors may request in such notice of election, subject to the
approval of the underwriter managing the offering as provided below. Thereupon,
the Company shall, as expeditiously as possible, use its best efforts to effect
the registration, on Form S-1 or Form S-2 (or any successor form), of all
Registrable Shares which the Company has been requested to so register.
Notwithstanding any other provision of this Section 4.2, if the managing
underwriter advises the holders of Registrable Shares initiating the
registration in writing that marketing factors require a limitation of the
number of shares to be underwritten, then the holders of Registrable Shares
initiating the registration shall so advise all holders of Registrable Shares
which would otherwise be included in the underwriting and the number of
Registrable Shares that may be included in the underwriting shall be allocated
among all such holders of Registrable Shares, including the holders of
Registrable Shares initiating the registration, in proportion (as nearly as
practicable) to the amount of Registrable Shares of the Company owned by each
such holder. If the managing underwriter does not limit the number of
Registrable Shares to be underwritten, the Company or other holders of
securities of the Company who have registration rights similar to those set
forth in Section 4.2 hereof may include Common Stock for their respective
accounts in such registration if the managing underwriter states that such
inclusion would not adversely affect the offering of Registrable Shares for any
reason and if the number of Registrable Shares which would otherwise have been
included in such registration and underwriting will not thereby be limited or
reduced.

                      (b) At any time after the Company becomes eligible to file
a Registration Statement on Form S-3 (or any successor form relating to
secondary offerings), an Investor or Investors holding in the aggregate at least
15% of the Registrable Shares may request in writing that the Company effect the
registration on Form S-3 (or such successor form), of Registrable Shares having
an aggregate offering price of at least $250,000 (based on the then current
public market price). Upon receipt of any such request, the Company shall
promptly give written notice of such proposed registration to all Investors.
Such Investors shall have the right, by giving written notice to the Company
within 30 days after the Company provides its notice, to elect to have included
in such registration such of their Registrable Shares as such Investors may
request in such notice of election. Thereupon, the Company



<PAGE>   6


shall, as expeditiously as possible, use its best efforts to effect the
registration on Form S-3, or such successor form, of all Registrable Shares
which the Company has been requested to register.

                      (c) The Company shall not be required to effect more than
two registrations pursuant to paragraph (a) above or more than four
registrations pursuant to paragraph (b) above. In addition, the Company shall
not be required to effect any registration (other than on Form S-3 or any
successor form relating to secondary offerings) within six months after the
effective date of any other Registration Statement of the Company.

                      (d) If at the time of any request to register Registrable
Shares pursuant to this Section 4.2, the Company is engaged or has fixed plans
to engage within 30 days of the time of the request in a registered public
offering as to which the Investors may include Registrable Shares pursuant to
Section 4.3 or is engaged in any other activity which, in the good faith
determination of the Company's Board of Directors, would be adversely affected
by the requested registration to the material detriment of the Company, then the
Company may at its option direct that such request be delayed for a period not
in excess of six months from the effective date of such offering or the date of
commencement of such other material activity, as the case may be, such right to
delay a request to be exercised by the Company not more than once in any two
year period.

               4.3    Incidental Registration.

                      (a) Whenever the Company proposes to file a Registration
Statement (other than pursuant to Section 4.2) at any time and from time to
time, it will, prior to such filing, give written notice to all Investors of its
intention to do so and, upon the written request of an Investor or Investors
given within 20 days after the Company provides such notice (which request shall
state the intended method of disposition of such Registrable Shares), the
Company shall use its best efforts to cause all Registrable Shares which the
Company has been requested by such Investor or Investors to register to be
registered under the Securities Act to the extent necessary to permit their sale
or other disposition in accordance with the intended methods of distribution
specified in the request of such Investor or Investors; provided that the
Company shall have the right to postpone or withdraw any registration effected
pursuant to this Section 4.3 without obligation to any Investor.

                      (b) In connection with any offering under this Section 4.3
involving an underwriting, the Company shall not be required to include any
Registrable Shares in such underwriting unless the holders thereof accept the
terms of the underwriting as agreed upon between the Company and the
underwriters selected by it, and then only in such quantity as will not, in the
opinion of the underwriters, jeopardize the success of the offering by the
Company. If in the opinion of the managing underwriter the registration of all,
or part of, the Registrable Shares which the holders have requested to be
included would materially and adversely affect such public offering, then the
Company shall be required to include in the underwriting only that number of
Registrable Shares which the managing underwriter believes may be sold without
causing such adverse effect; provided, however, that in no event shall the
amount of Registrable Shares included in the registration be reduced below
twenty-five percent (25%) of the total amount of securities included in such
registration, unless such offering is the



<PAGE>   7


initial underwritten public offering of the Company's securities, in which event
any or all of the Registrable Shares requested to be included in the
registration may be excluded. If the number of Registrable Shares to be included
in the underwriting in accordance with the foregoing is less than the total
number of shares which the holders of Registrable Shares have requested to be
included, then the holders of Registrable Shares who have requested registration
and other holders of shares of Common Stock entitled to include shares of Common
Stock in such registration shall participate in the underwriting pro rata based
upon their total ownership of shares of Common Stock of the Company. If any
holder would thus be entitled to include more shares than such holder requested
to be registered, the excess shall be allocated among other requesting holders
pro rata based upon their total ownership of Registrable Shares.

               4.4 Registration Procedures. If and whenever the Company is
required by the provisions of this Agreement to use its best efforts to effect
the registration of any of the Registrable Shares under the Securities Act, the
Company shall:

                      (a) file with the Commission a Registration Statement with
respect to such Registrable Shares and use its best efforts to cause that
Registration Statement to become and remain effective;

                      (b) as expeditiously as possible prepare and file with the
Commission any amendments and supplements to the Registration Statement and the
prospectus included in the Registration Statement as may be necessary to keep
the Registration Statement effective for a period of not less than 120 days from
the effective date;

                      (c) as expeditiously as possible furnish to each selling
Investor such reasonable numbers of copies of the prospectus, including a
preliminary prospectus, in conformity with the requirements of the Securities
Act, and such other documents as the selling Investor may reasonably request in
order to facilitate the public sale or other disposition of the Registrable
Shares owned by the selling Investor; and

                      (d) as expeditiously as possible use its best efforts to
register or qualify the Registrable Shares covered by the Registration Statement
under the securities or Blue Sky laws of such states as the selling Investors
shall reasonably request, and do any and all other acts and things that may be
necessary or desirable to enable the selling Investors to consummate the public
sale or other disposition in such states of the Registrable Shares owned by the
selling Investor; provided, however, that the Company shall not be required in
connection with this paragraph (d) to qualify as a foreign corporation or
execute a general consent to service of process in any jurisdiction.

        If the Company has delivered preliminary or final prospectuses to the
selling Investors and after having done so the prospectus is amended to comply
with the requirements of the Securities Act, the Company shall promptly notify
the selling Investors and, if requested, the selling Investors shall immediately
cease making offers of Registrable Shares and return all prospectuses to the
Company. The



<PAGE>   8



Company shall promptly provide the selling Investors with revised prospectuses
and, following receipt of the revised prospectuses, the selling Investors shall
be free to resume making offers of the Registrable Shares.

               4.5 Allocation of Expenses. The Company will pay all Registration
Expenses of all registrations under this Agreement; provided, however, that if a
registration is withdrawn at the request of the Investors requesting such
registration (other than as a result of information concerning the business or
financial condition of the Company which is made known to the Investors after
the date on which such registration was requested) and if the requesting
Investors elect not to have such registration counted as a registration
requested under Section 4.2, the requesting Investors shall pay the Registration
Expenses of such registration pro rata in accordance with the number of their
Registrable Shares included in such registration. For purposes of this Section,
the term "Registration Expenses" shall mean all expenses incurred by the Company
in complying with this Agreement including, without limitation, all registration
and filing fees, exchange listing fees, printing expenses, fees and
disbursements of counsel for the Company and the fees and expenses of one
counsel selected by the selling Investors to represent the selling Investors,
state Blue Sky fees and expenses, and the expense of any special audits incident
to or required by any such registration, but excluding underwriting discounts,
selling commissions and the fees and expenses of selling Investors' own counsel
(other than the counsel selected to represent all selling Investors).

               4.6 Indemnification. In the event of any registration of any of
the Registrable Shares under the Securities Act pursuant to this Agreement, the
Company will indemnify and hold harmless the seller of such Registrable Shares,
each underwriter of such Registrable Shares, and each other person, if any, who
controls such seller or underwriter within the meaning of the Securities Act or
the Exchange Act against any losses, claims, damages or liabilities, joint or
several, to which such seller, underwriter or controlling person may become
subject under the Securities Act, the Exchange Act, state securities or Blue Sky
laws or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in any Registration
Statement under which such Registrable Shares were registered under the
Securities Act, any preliminary prospectus or final prospectus contained in the
Registration Statement, or any amendment or supplement to such Registration
Statement, or arise out of or are based upon the omission or alleged omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading; and the Company will reimburse such seller,
underwriter and each such controlling person for any legal or any other expenses
reasonably incurred by such seller, underwriter or controlling person in
connection with investigating or defending any such loss, claim, damage,
liability or action as such expenses are incurred; provided, however, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any untrue statement
or omission made in such Registration Statement, preliminary prospectus or
prospectus, or any such amendment or supplement, in reliance upon and in
conformity with information furnished to the Company, in writing, by or on
behalf of such seller, underwriter or controlling person specifically for use in
the preparation thereof.



<PAGE>   9



        In the event of any registration of any of the Registrable Shares under
the Securities Act pursuant to this Agreement, each seller of Registrable
Shares, severally and not jointly, will indemnify and hold harmless the Company,
each of its directors and officers and each underwriter (if any) and each
person, if any, who controls the Company or any such underwriter within the
meaning of the Securities Act or the Exchange Act, against any losses, claims,
damages or liabilities, joint or several, to which the Company, such directors
and officers, underwriter or controlling person may become subject under the
Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement under which
such Registrable Shares were registered under the Securities Act, any
preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or supplement to the Registration Statement, or
arise out of or are based upon any omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, if the statement or omission was made in reliance upon
and in conformity with information furnished in writing to the Company by or on
behalf of such seller, specifically for use in connection with the preparation
of such Registration Statement, prospectus, amendment or supplement; provided,
however, that the obligations of such Stockholders hereunder shall be limited to
an amount equal to the proceeds to each Stockholder of Registrable Shares sold
as contemplated herein.

        Each party entitled to indemnification under this Section 4.6 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; provided, that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld); and, provided, further, that the failure of any Indemnified Party to
give notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Agreement unless the Indemnifying Party is adversely
affected by such failure. The Indemnified Party may participate in such defense
at such party's expense; provided, however, that the Indemnifying Party shall
pay such expense if representation of such Indemnified Party by the counsel
retained by the Indemnifying Party would be inappropriate due to actual or
potential differing interests between the Indemnified Party and any other party
represented by such counsel in such proceeding. No Indemnifying Party, in the
defense of any such claim or litigation shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect of such claim or litigation, and no Indemnified Party shall consent
to entry of any judgment or settle such claim or litigation without the prior
written consent of the Indemnifying Party.

               4.7 Indemnification with Respect to Underwritten Offering. In the
event that Registrable Shares are sold pursuant to a Registration Statement in
an underwritten offering pursuant to Section 4.2(a), the Company agrees to enter
into an underwriting agreement containing customary representations and
warranties with respect to the business and operations of an issuer of the
securities



<PAGE>   10



being registered and customary covenants and agreements to be performed by such
issuer, including without limitation customary provisions with respect to
indemnification by the Company of the underwriters of such offering.

               4.8 Information by Holder. Each holder of Registrable Shares
included in any registration shall furnish to the Company such information
regarding such holder and the distribution proposed by such holder as the
Company may request in writing and as shall be required in connection with any
registration, qualification or compliance referred to in this Agreement.

               4.9 "Stand-Off" Agreement. Each Investor, if requested by the
Company and an underwriter of Common Stock or other securities of the Company,
shall agree not to sell or otherwise transfer or dispose of any Registrable
Shares or other securities of the Company held by such Stockholder for a
specified period of time (not to exceed 180 days) following the effective date
of a Registration Statement; provided, that:

                      (a) such agreement shall only apply to the first such
Registration Statement covering Common Stock of the Company to be sold on its
behalf to the public in an underwritten offering; and

                      (b) all officers and directors of the Company enter into
similar agreements.

Such agreement shall be in writing in a form satisfactory to the Company and
such underwriter. The Company may impose stop-transfer instructions with respect
to the Registrable Shares or other securities subject to the foregoing
restriction until the end of the stand-off period.

               4.10 Limitations on Subsequent Registration Rights. The Company
shall not, without the prior written consent of Investors holding at least a
majority of the Registrable Shares, enter into any agreement (other than this
Agreement) with any holder or prospective holder of any securities of the
Company which would allow such holder or prospective holder to include
securities of the Company in any registration filed under Sections 4.2 or 4.3
that would reduce the number of Registrable Shares includable by the Investors
under this Agreement.

               4.11 Rule 144 Requirements. After the earliest of (i) the closing
of the sale of securities of the Company pursuant to a Registration Statement,
(ii) the registration by the Company of a class of securities under Section 12
of the Exchange Act, or (iii) the issuance by the Company of an offering
circular pursuant to Regulation A under the Securities Act, the Company agrees
to:

                      (a) make and keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act;

                      (b) use its best efforts to file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements); and



<PAGE>   11



                      (c) furnish to any holder of Registrable Shares upon
request a written statement by the Company as to its compliance with the
reporting requirements of said Rule 144 (at any time after 90 days following the
closing of the first sale of securities by the Company pursuant to a
Registration Statement), and of the Securities Act and the Exchange Act (at any
time after it has become subject to such reporting requirements), a copy of the
most recent annual or quarterly report of the Company, and such other reports
and documents of the Company as such holder may reasonably request to avail
itself of any similar rule or regulation of the Commission allowing it to sell
any such securities without registration.

        5.     Transfers of Certain Rights.

               5.1 In General. The rights granted to each Investor pursuant to
the terms of Sections 2, 3 and 4 of this Agreement may be transferred by such
Investor to another Investor, to any affiliate of such Investor or to any person
or entity acquiring at least 50,000 Registrable Shares (such number being
subject to adjustment for any stock dividend, stock split, subdivision,
combination or other recapitalization of the Common Stock of the Company);
provided, however, that the Company is given written notice by the transferee at
the time of such transfer stating the name and address of the transferee and
identifying the securities with respect to which such rights are being assigned;
and provided further, however, that the Company receives the written instrument
provided in Section 5.2 below.

               5.2 Transferees. Any transferee to whom rights hereunder are
transferred shall, as a condition to such transfer, deliver to the Company a
written instrument by which such transferee agrees to be bound by the
obligations imposed upon Investors under this Agreement to the same extent as if
such transferee were a party hereto.

               5.3 Subsequent Transferees. A transferee to whom rights are
transferred pursuant to this Section 5 may not again transfer such rights to any
other person or entity, other than as provided in Section 5.1 or 5.2 above.

               5.4 Partners and Stockholders. Notwithstanding anything to the
contrary herein, any Investor which is a partnership or corporation may transfer
rights granted to such Investor hereunder to any partner or stockholder thereof
who delivers to the Company a written instrument in accordance with Section 5.2
above and containing the representation that the transfer is exempt from
registration under the Securities Act. In the event of such transfer, such
partner or stockholder shall be deemed a Investor for purposes of this Section 5
and may again transfer such rights to any other person or entity which acquires
Registrable Shares from such partner or stockholder, in accordance with, and
subject to, the provisions of this Section 5.

        6. Confidentiality. Each Investor agrees that he or it will keep
confidential and will not disclose or divulge any confidential, proprietary or
secret information which such Investor may obtain from the Company pursuant to
financial statements, reports and other materials submitted by the Company to
such Investor pursuant to this Agreement, or pursuant to visitation or
inspection rights granted hereunder, unless such information is known, or until
such information becomes known, to the



<PAGE>   12



public. Notwithstanding the foregoing, an Investor that is a partnership may
disclose summary financial and operating information to its limited partners if
required by its partnership agreement.

        7.     Voting Covenants.

               7.1    Voting of Shares.

                      (a) In any and all elections of directors of the Company
(whether at a meeting or by written consent in lieu of a meeting), each Investor
and Management Stockholder (collectively the "Stockholders") shall vote or cause
to be voted all Shares (as defined in Section 7.2 below) owned by him or it, or
over which he or it has voting control, and otherwise use his or its respective
best efforts, so as to fix the number of directors of the Company at five and to
elect (i) one member designated by the holders of the Company's Series A
Preferred Stock (which designee shall be designated by Medical Science Partners,
L.P. ("MSP"), and who shall initially be Andre L. Lamotte); (ii) one member
designated by the holders of the Company's Series B Preferred Stock (which
designee shall be designated by Sprout Capital VII, L.P. ("Sprout"), and who
shall initially be Robert Curry); (iii) the then duly elected, qualified and
acting President of the Company (currently David H. Maupin); and (iv) two
members designated jointly by the President of the Company and all holders of
the Company's Preferred Stock, by action of the President and the holders of a
majority of the Shares held by such holders.

                      (b) The Company shall provide the Stockholders with 20
days' prior written notice of any intended mailing of a notice to stockholders
for a meeting at which directors are to be elected. The Stockholders shall give
written notice to all other parties to this Agreement, no later than 10 days
prior to such mailing, of the persons designated by the Stockholders pursuant to
Section 7.1(a) as nominees for election as directors. If the Stockholders shall
fail to give notice to the Company as provided above, it shall be deemed that
the designees of the Stockholders, then serving as directors shall be their
designees for reelection.

                      (c) The Management Stockholders shall not vote to remove
any director designated by the holders of the Company's Preferred Stock, except
for bad faith or willful misconduct.

               7.2 Shares. "Shares" shall mean and include any and all shares of
Common Stock and/or shares of capital stock of the Company, by whatever name
called, which carry voting rights (including voting rights which arise by reason
of default) and shall include any shares now owned or subsequently acquired by a
Stockholder, however acquired, including without limitation stock splits and
stock dividends.

               7.3 Amendment, Waiver and Termination. This Section 7 may only be
modified, waived or amended in writing signed by MSP, Sprout and the holders of
a majority of the then outstanding shares of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock, each voting as a separate class.
This Section 7 shall terminate in its entirety upon the closing of a Qualified
Public Offering.



<PAGE>   13



               7.4 No Revocation. The voting agreements contained herein are
coupled with an interest and may not be revoked, except by written consent of
all of the Stockholders.

               7.5 Indemnification. In the event that any director elected
pursuant to this Section 7 shall be made or threatened to be made a party to any
action, suit or proceeding with respect to which he may be entitled to
indemnification by the Company pursuant to its Certificate of Incorporation or
Bylaws, or otherwise, he shall be entitled to be represented in such action,
suit or proceeding by counsel of his choice and the reasonable expenses of such
representation shall be reimbursed by the Company to the extent provided in or
authorized by said Certificate of Incorporation or Bylaws. Each Stockholder
agrees not to take any action to amend any provisions of the Certificate of
Incorporation or the Bylaws of the Company relating to indemnification of
directors, as presently in effect, without the prior written consent of all of
the Stockholders.

               7.6 Restrictive Legend. All certificates representing Shares
owned or hereafter acquired by the Stockholders or any transferee of the
Stockholders bound by this Agreement shall have affixed thereto a legend
substantially in the following form:

               THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
               TO CERTAIN VOTING AGREEMENTS AS SET FORTH IN AN INVESTORS RIGHTS
               AGREEMENT BY AND AMONG THE REGISTERED OWNER OF THIS CERTIFICATE,
               THE COMPANY AND CERTAIN OTHER STOCKHOLDERS OF THE COMPANY, A COPY
               OF WHICH IS AVAILABLE FOR INSPECTION AT THE OFFICES OF THE
               SECRETARY OF THE COMPANY.

               7.7 Transfers of Rights. Any transferee to whom Shares are
transferred by a Stockholder, whether voluntarily or by operation of law, shall
be bound by the voting obligations imposed upon the transferor under this
Agreement, and shall be entitled to the rights granted to the transferor under
this Agreement, to the same extent as if such transferee were a Stockholder
hereunder.

        8.     Waivers and Amendments.

               8.1 Waivers. Certain Investors, as the holders of a majority of
the Registerable Shares (as defined in the Prior Agreement), hereby waive on
behalf of all Investors any right of first refusal which the Investors may have
under the Prior Agreement or otherwise to purchase any of the shares of the
Company's Series C Preferred Stock pursuant to the Stock Purchase Agreement.

               8.2 Termination of Prior Agreement. The Company and the Investors
and Management Stockholders hereby terminate the Prior Agreement in its entirety
and replace such agreement with the provisions of this Restated Investors Rights
Agreement. For purposes of Section 7 of the Prior Agreement, MSP, Sprout and the
holders of a majority of the outstanding shares of Series A Preferred Stock and
Series B Preferred Stock, each voting as a separate class, hereby consent and
agree to such termination. It is understood and acknowledged that termination of
the Prior

Agreement shall not affect in any way the termination of Sections 7, 8 (except
for subsection 8.2), 9 and 10 of the Series A Agreement pursuant to subsection
8.2 of the Prior Agreement, nor shall it affect the termination of the Voting
Agreement (as defined in the Prior Agreement) pursuant to subsection 8.3 of the
Prior Agreement, all of which shall be and remain terminated unless expressly
agreed otherwise in writing by the Company and the Investors hereunder.

        9.     General Provisions.

               9.1 Governing Law. All questions concerning the construction,
validity and interpretation of this Agreement shall be governed by and construed
in accordance with the domestic laws of the State of Delaware, without giving
effect to any choice of law or conflict of law provision or rule (whether of the
State of Delaware or any other jurisdiction) that would cause the application of
the laws of any jurisdiction other than the State of Delaware.

               9.2 Successors and Assigns. Except as otherwise expressly
provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors, and administrators of
the parties hereto.

               9.3 Entire Agreement. This Agreement constitutes the full and
entire understanding and agreement among the parties with regard to the subjects
hereof and no party shall be liable or bound to any other party in any manner by
any representations, warranties, covenants, or agreements except as specifically
set forth herein. Nothing in this Agreement, express or implied, is intended to
confer upon any party, other than the parties hereto and their respective
successors and assigns, any rights, remedies, obligations, or liabilities under
or by reason of this Agreement, except as expressly provided herein.

               9.4 Severability. In case any provision of this Agreement becomes
or is declared by a court of competent jurisdiction to be illegal, unenforceable
or void, this Agreement shall continue in full force and effect without said
provision; provided, however, that no such severability shall be effective if it
materially changes the economic benefit of this Agreement to any party.

               9.5 Specific Performance. In addition to any and all other
remedies that may be available at law in the event of any breach of this
Agreement, the Company and each Stockholder shall be entitled to specific
performance of the agreements and obligations of the Company and the
Stockholders hereunder and to such other injunctive or other equitable relief as
may be granted by a court of competent jurisdiction.

               9.6 Amendment and Waiver. With the written consent of the Company
and the holders of more than 50% of the Registrable Shares, the obligations of
the Company and the rights of the Stockholders under this Agreement may be
waived (either generally or in a particular instance, either retroactively or
prospectively and either for a specified period of time or indefinitely), and
with the same consent the Company, when authorized by resolution of its board of
directors, may enter into a supplementary agreement for the purpose of adding
any provisions to or changing in any manner or



<PAGE>   15



eliminating any of the provisions of this Agreement; provided, however, that no
such waiver or supplemental agreement shall reduce the aforesaid percentage of
Registrable Shares, the holders of which are required to consent to any waiver
or supplemental agreement without the consent of the holders of all of the
Registrable Shares; and provided, further, that such provisions shall not apply
to the amendment or waiver of any provision of Section 7, the amendment or
waiver of which shall be governed by Section 7.3. Neither this Agreement nor any
provision hereof may be changed, waived, discharged or terminated orally, but
only by a signed statement in writing. Any amendment, waiver or supplementary
agreement effected in accordance with this paragraph shall be binding upon each
holder of any Registrable Shares then outstanding, each future holder of all
such Registrable Shares and the Company.

               9.7 Delays or Omissions. No delay or omission to exercise any
right, power, or remedy accruing to the Company or the Stockholders (or any of
their permitted assigns) upon any breach, default or noncompliance under this
Agreement shall impair any such right, power, or remedy, nor shall it be
construed to be a waiver of any such breach, default or noncompliance, or any
acquiescence therein, or of any similar breach, default or noncompliance
thereafter occurring. Any waiver, permit, consent, or approval of any kind or
character on the Company's or the Stockholders' part of any breach, default or
noncompliance under this Agreement or any waiver on the Company's or the
Stockholders' part of any provisions or conditions of this Agreement must be in
writing and shall be effective only to the extent specifically set forth in such
writing, and that all remedies, either under this Agreement, by law, or
otherwise afforded to the Company or the Stockholders, shall be cumulative and
not alternative.

permitted hereunder shall be in writing and shall be deemed effectively given

the mail.

               9.9 Titles and Subtitles. The titles of the sections of this
Agreement are for convenience of reference only and are not to be considered in

                            INDEMNIFICATION AGREEMENT


       This Indemnification Agreement ("Agreement") is effective as of April
____, 1998, by and between UroSurge, Inc., a Delaware corporation (the
"Company"), and _______________ ("Indemnitee").

       WHEREAS, the Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and its related
entities;

       WHEREAS, in order to induce Indemnitee to continue to provide services to
the Company, the Company wishes to provide for the indemnification of, and the
advancement of expenses to, Indemnitee to the maximum extent permitted by law;

       WHEREAS, the Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for the Company's directors, officers, employees,
agents and fiduciaries, the significant increases in the cost of such insurance
and the general reductions in the coverage of such insurance;

       WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting directors, officers,
employees, agents and fiduciaries to expensive litigation risks at the same time
as the availability and coverage of liability insurance has been severely
limited; and

       WHEREAS, the Company and Indemnitee desire to continue to have in place
the additional protection provided by an indemnification agreement and to
provide indemnification and advancement of expenses to the Indemnitee to the
maximum extent permitted by Delaware law;

       WHEREAS, in view of the considerations set forth above, the Company
desires that Indemnitee shall be indemnified and advanced expenses by the
Company as set forth herein;

       NOW, THEREFORE, the Company and Indemnitee hereby agree as set forth
below.

       1.     Certain Definitions.

              (a)    "Change in Control" shall mean, and shall be deemed to have
occurred if, on or after the date of this Agreement, (i) any "person" (as such
term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934,
as amended, (the "Exchange Act")), other than a trustee or other fiduciary
holding securities under an employee benefit plan of the Company acting in such
capacity or a corporation owned directly or indirectly by the stockholders of
the Company in substantially the same proportions as their ownership of stock of
the Company, becomes the "beneficial owner" (as defined in Rule 13d-3 under said
Exchange Act), directly or indirectly, of


<PAGE>   2
securities of the Company representing more than 50% of the total voting power
represented by the Company's then outstanding Voting Securities, (ii) during any
period of two consecutive years, individuals who at the beginning of such period
constitute the Board of Directors of the Company and any new director whose
election by the Board of Directors or nomination for election by the Company's
stockholders was approved by a vote of at least two thirds (2/3) of the
directors then still in office who either were directors at the beginning of the
period or whose election or nomination for election was previously so approved,
cease for any reason to constitute a majority thereof, or (iii) the stockholders
of the Company approve a merger or consolidation of the Company with any other
corporation other than a merger or consolidation which would result in the
Voting Securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into Voting Securities of the surviving entity) at least 80% of the total voting
power represented by the Voting Securities of the Company or such surviving
entity outstanding immediately after such merger or consolidation, or the
stockholders of the Company approve a plan of complete liquidation of the
Company or an agreement for the sale or disposition by the Company of (in one
transaction or a series of related transactions) all or substantially all of the
Company's assets.

              (b)    "Claim" shall mean with respect to a Covered Event: any
threatened, pending or completed action, suit, proceeding or alternative dispute
resolution mechanism, or any hearing, inquiry or investigation that Indemnitee
in good faith believes might lead to the institution of any such action, suit,
proceeding or alternative dispute resolution mechanism, whether civil, criminal,
administrative, investigative or other.

              (c)    References to the "Company" shall include, in addition to
UroSurge, Inc., any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger to which UroSurge, Inc. (or
any of its wholly owned subsidiaries) is a party which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, employees, agents or fiduciaries, so that if Indemnitee is
or was a director, officer, employee, agent or fiduciary of such constituent
corporation, or is or was serving at the request of such constituent corporation
as a director, officer, employee, agent or fiduciary of another corporation,
partnership, joint venture, employee benefit plan, trust or other enterprise,
Indemnitee shall stand in the same position under the provisions of this
Agreement with respect to the resulting or surviving corporation as Indemnitee
would have with respect to such constituent corporation if its separate
existence had continued.

              (d)    "Covered Event" shall mean any event or occurrence related
to the fact that Indemnitee is or was a director, officer, employee, agent or
fiduciary of the Company, or any subsidiary of the Company, or is or was serving
at the request of the Company as a director, officer, employee, agent or
fiduciary of another corporation, partnership, joint venture, trust or other
enterprise, or by reason of any action or inaction on the part of Indemnitee
while serving in such capacity.

<PAGE>   3
              (e)    "Expenses" shall mean any and all expenses (including
attorneys' fees and all other costs, expenses and obligations incurred in
connection with investigating, defending, being a witness in or participating in
(including on appeal), or preparing to defend, to be a witness in or to
participate in, any action, suit, proceeding, alternative dispute resolution
mechanism, hearing, inquiry or investigation), judgments, fines, penalties and
amounts paid in settlement (if such settlement is approved in advance by the
Company, which approval shall not be unreasonably withheld), actually and
reasonably incurred, of any Claim and any federal, state, local or foreign taxes
imposed on the Indemnitee as a result of the actual or deemed receipt of any
payments under this Agreement.

              (f)    "Expense Advance" shall mean a payment to Indemnitee
pursuant to Section 3 of Expenses in advance of the settlement of or final
judgement in any action, suit, proceeding or alternative dispute resolution
mechanism, hearing, inquiry or investigation which constitutes a Claim.

              (g)    "Independent Legal Counsel" shall mean an attorney or firm
of attorneys, selected in accordance with the provisions of Section 2(d) hereof,
who shall not have otherwise performed services for the Company or Indemnitee
within the last three years (other than with respect to matters concerning the
rights of Indemnitee under this Agreement, or of other indemnitees under similar
indemnity agreements).

              (h)    References to "other enterprises" shall include employee
benefit plans; references to "fines" shall include any excise taxes assessed on
Indemnitee with respect to an employee benefit plan; and references to "serving
at the request of the Company" shall include any service as a director, officer,
employee, agent or fiduciary of the Company which imposes duties on, or involves
services by, such director, officer, employee, agent or fiduciary with respect
to an employee benefit plan, its participants or its beneficiaries; and if
Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to
be in the interest of the participants and beneficiaries of an employee benefit
plan, Indemnitee shall be deemed to have acted in a manner "not opposed to the
best interests of the Company" as referred to in this Agreement.

              (i)    "Reviewing Party" shall mean, subject to the provisions of
Section 2(d), any person or body appointed by the Board of Directors in
accordance with applicable law to review the Company's obligations hereunder and
under applicable law, which may include a member or members of the Company's
Board of Directors, Independent Legal Counsel or any other person or body not a
party to the particular Claim for which Indemnitee is seeking indemnification.

              (j)    "Section" refers to a section of this Agreement unless
otherwise indicated.

              (k)    "Voting Securities" shall mean any securities of the
Company that vote generally in the election of directors.


                                      -3-
<PAGE>   4
       2.     Indemnification.

              (a)    Indemnification of Expenses. Subject to the provisions of
Section 2(b) below, the Company shall indemnify Indemnitee for Expenses to the
fullest extent permitted by law if Indemnitee was or is or becomes a party to or
witness or other participant in, or is threatened to be made a party to or
witness or other participant in, any Claim (whether by reason of or arising in
part out of a Covered Event), including all interest, assessments and other
charges paid or payable in connection with or in respect of such Expenses.

              (b)    Review of Indemnification Obligations. Notwithstanding the
foregoing, in the event any Reviewing Party shall have determined (in a written
opinion, in any case in which Independent Legal Counsel is the Reviewing Party)
that Indemnitee is not entitled to be indemnified hereunder under applicable
law, (i) the Company shall have no further obligation under Section 2(a) to make
any payments to Indemnitee not made prior to such determination by such
Reviewing Party, and (ii) the Company shall be entitled to be reimbursed by
Indemnitee (who hereby agrees to reimburse the Company) for all Expenses
theretofore paid in indemnifying Indemnitee; provided, however, that if
Indemnitee has commenced or thereafter commences legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee is entitled to
be indemnified hereunder under applicable law, any determination made by any
Reviewing Party that Indemnitee is not entitled to be indemnified hereunder
under applicable law shall not be binding and Indemnitee shall not be required
to reimburse the Company for any Expenses theretofore paid in indemnifying
Indemnitee until a final judicial determination is made with respect thereto (as
to which all rights of appeal therefrom have been exhausted or lapsed).
Indemnitee's obligation to reimburse the Company for any Expenses shall be
unsecured and no interest shall be charged thereon.

              (c)    Indemnitee Rights on Unfavorable Determination; Binding
Effect. If any Reviewing Party determines that Indemnitee substantively is not
entitled to be indemnified hereunder in whole or in part under applicable law,
Indemnitee shall have the right to commence litigation seeking an initial
determination by the court or challenging any such determination by such
Reviewing Party or any aspect thereof, including the legal or factual bases
therefor, and, subject to the provisions of Section 15, the Company hereby
consents to service of process and to appear in any such proceeding. Absent such
litigation, any determination by any Reviewing Party shall be conclusive and
binding on the Company and Indemnitee.

              (d)    Selection of Reviewing Party; Change in Control. If there
has not been a Change in Control, any Reviewing Party shall be selected by the
Board of Directors, and if there has been such a Change in Control (other than a
Change in Control which has been approved by a majority of the Company's Board
of Directors who were directors immediately prior to such Change in Control),
any Reviewing Party with respect to all matters thereafter arising concerning
the rights of Indemnitee to indemnification of Expenses under this Agreement or
any other agreement or under the Company's Certificate of Incorporation or
Bylaws as now or hereafter in effect, or under any other applicable law, if
desired by Indemnitee, shall be Independent Legal Counsel selected by


                                      -4-
<PAGE>   5
Indemnitee and approved by the Company (which approval shall not be unreasonably
withheld). Such counsel, among other things, shall render its written opinion to
the Company and Indemnitee as to whether and to what extent Indemnitee would be
entitled to be indemnified hereunder under applicable law and the Company agrees
to abide by such opinion. The Company agrees to pay the reasonable fees of the
Independent Legal Counsel referred to above and to indemnify fully such counsel
against any and all expenses (including attorneys' fees), claims, liabilities
and damages arising out of or relating to this Agreement or its engagement
pursuant hereto. Notwithstanding any other provision of this Agreement, the
Company shall not be required to pay Expenses of more than one Independent Legal
Counsel in connection with all matters concerning a single Indemnitee, and such
Independent Legal Counsel shall be the Independent Legal Counsel for any or all
other Indemnitees unless (i) the Company otherwise determines or (ii) any
Indemnitee shall provide a written statement setting forth in detail a
reasonable objection to such Independent Legal Counsel representing other
Indemnitees.

              (e)    Mandatory Payment of Expenses. Notwithstanding any other
provision of this Agreement other than Section 10 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
Claim, Indemnitee shall be indemnified against all Expenses incurred by
Indemnitee in connection therewith.

       3.     Expense Advances.

              (a)    Obligation to Make Expense Advances. Upon receipt of a
written undertaking by or on behalf of the Indemnitee to repay such amounts if
it shall ultimately be determined that the Indemnitee is not entitled to be
indemnified therefor by the Company, the Company shall make Expense Advances to
Indemnitee.

              (b)    Form of Undertaking. Any written undertaking by the
Indemnitee to repay any Expense Advances hereunder shall be unsecured and no
interest shall be charged thereon.

              (c)    Determination of Reasonable Expense Advances. The parties
agree that for the purposes of any Expense Advance for which Indemnitee has made
written demand to the Company in accordance with this Agreement, all Expenses
included in such Expense Advance that are certified by affidavit of Indemnitee's
counsel as being reasonable shall be presumed conclusively to be reasonable.

       4.     Procedures for Indemnification and Expense Advances.

              (a)    Timing of Payments. All payments of Expenses (including
without limitation Expense Advances) by the Company to the Indemnitee pursuant
to this Agreement shall be made to the fullest extent permitted by law as soon
as practicable after written demand by Indemnitee therefor is presented to the
Company, but in no event later than forty-five (45) business days after


                                      -5-
<PAGE>   6
such written demand by Indemnitee is presented to the Company, except in the
case of Expense Advances, which shall be made no later than twenty (20) business
days after such written demand by Indemnitee is presented to the Company.

              (b)    Notice/Cooperation by Indemnitee. Indemnitee shall, as a
condition precedent to Indemnitee's right to be indemnified or Indemnitee's
right to receive Expense Advances under this Agreement, give the Company notice
in writing as soon as practicable of any Claim made against Indemnitee for which
indemnification will or could be sought under this Agreement. Notice to the
Company shall be directed to the Chief Executive Officer of the Company at the
address shown on the signature page of this Agreement (or such other address as
the Company shall designate in writing to Indemnitee). In addition, Indemnitee
shall give the Company such information and cooperation as it may reasonably
require and as shall be within Indemnitee's power.

              (c)    No Presumptions; Burden of Proof. For purposes of this
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval) or conviction, or upon a plea of nolo
contendere, or its equivalent, shall not create a presumption that Indemnitee
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by this
Agreement or applicable law. In addition, neither the failure of any Reviewing
Party to have made a determination as to whether Indemnitee has met any
particular standard of conduct or had any particular belief, nor an actual
determination by any Reviewing Party that Indemnitee has not met such standard
of conduct or did not have such belief, prior to the commencement of legal
proceedings by Indemnitee to secure a judicial determination that Indemnitee
should be indemnified under this Agreement or applicable law, shall be a defense
to Indemnitee's claim or create a presumption that Indemnitee has not met any
particular standard of conduct or did not have any particular belief. In
connection with any determination by any Reviewing Party or otherwise as to
whether the Indemnitee is entitled to be indemnified hereunder, the burden of
proof shall be on the Company to establish that Indemnitee is not so entitled.

              (d)    Notice to Insurers. If, at the time of the receipt by the
Company of a notice of a Claim pursuant to Section 4(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim to the insurers in accordance
with the procedures set forth in the respective policies. The Company shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of the Indemnitee, all amounts payable as a result of such Claim in
accordance with the terms of such policies.

              (e)    Selection of Counsel. In the event the Company shall be
obligated hereunder to provide indemnification for or make any Expense Advances
with respect to the Expenses of any Claim, the Company, if appropriate, shall be
entitled to assume the defense of such Claim with counsel approved by Indemnitee
(which approval shall not be unreasonably withheld) upon the delivery to
Indemnitee of written notice of the Company's election to do so. After delivery
of such


                                      -6-
<PAGE>   7
notice, approval of such counsel by Indemnitee and the retention of such counsel
by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees or expenses of separate counsel subsequently employed by
or on behalf of Indemnitee with respect to the same Claim; provided that, (i)
Indemnitee shall have the right to employ Indemnitee's separate counsel in any
such Claim at Indemnitee's expense and (ii) if (A) the employment of separate
counsel by Indemnitee has been previously authorized by the Company, (B)
Indemnitee shall have reasonably concluded that there may be a conflict of
interest between the Company and Indemnitee in the conduct of any such defense,
or (C) the Company shall not continue to retain such counsel to defend such
Claim, then the fees and expenses of Indemnitee's separate counsel shall be
Expenses for which Indemnitee may receive indemnification or Expense Advances
hereunder.

       5.     Additional Indemnification Rights; Nonexclusivity.

              (a)    Scope. The Company hereby agrees to indemnify the
Indemnitee to the fullest extent permitted by law, notwithstanding that such
indemnification is not specifically authorized by the other provisions of this
Agreement, the Company's Certificate of Incorporation, the Company's Bylaws or
by statute. In the event of any change after the date of this Agreement in any
applicable law, statute or rule which expands the right of a Delaware
corporation to indemnify a member of its board of directors or an officer,
employee, agent or fiduciary, it is the intent of the parties hereto that
Indemnitee shall enjoy by this Agreement the greater benefits afforded by such
change. In the event of any change in any applicable law, statute or rule which
narrows the right of a Delaware corporation to indemnify a member of its board
of directors or an officer, employee, agent or fiduciary, such change, to the
extent not otherwise required by such law, statute or rule to be applied to this
Agreement, shall have no effect on this Agreement or the parties' rights and
obligations hereunder except as set forth in Section 10(a) hereof.

              (b)    Nonexclusivity. The indemnification and the payment of
Expense Advances provided by this Agreement shall be in addition to any rights
to which Indemnitee may be entitled under the Company's Certificate of
Incorporation, its Bylaws, any other agreement, any vote of stockholders or
disinterested directors, the General Corporation Law of the State of Delaware,
or otherwise. The indemnification and the payment of Expense Advances provided
under this Agreement shall continue as to Indemnitee for any action taken or not
taken while serving in an indemnified capacity even though subsequent thereto
Indemnitee may have ceased to serve in such capacity.

       6.     No Duplication of Payments. The Company shall not be liable under
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, provision of the Company's Certificate of
Incorporation, Bylaws or otherwise) of the amounts otherwise payable hereunder.


                                      -7-
<PAGE>   8
       7.     Partial Indemnification. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

       8.     Mutual Acknowledgement. Both the Company and Indemnitee
acknowledge that in certain instances, federal law or applicable public policy
may prohibit the Company from indemnifying its directors, officers, employees,
agents or fiduciaries under this Agreement or otherwise. Indemnitee understands
and acknowledges that the Company has undertaken or may be required in the
future to undertake with the Securities and Exchange Commission to submit the
question of indemnification to a court in certain circumstances for a
determination of the Company's right under public policy to indemnify
Indemnitee.

       9.     Liability Insurance. To the extent the Company maintains liability
insurance applicable to directors, officers, employees, agents or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are provided to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, if Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, agents or fiduciaries, if Indemnitee
is not an officer or director but is a key employee, agent or fiduciary.

       10.    Exceptions. Notwithstanding any other provision of this Agreement,
the Company shall not be obligated pursuant to the terms of this Agreement:

              (a)    Excluded Action or Omissions. To indemnify Indemnitee for
Expenses resulting from acts, omissions or transactions for which Indemnitee is
prohibited from receiving indemnification under this Agreement or applicable
law; provided, however, that notwithstanding any limitation set forth in this
Section10(a) regarding the Company's obligation to provide indemnification,
Indemnitee shall be entitled under Section 3 to receive Expense Advances
hereunder with respect to any such Claim unless and until a court having
jurisdiction over the Claim shall have made a final judicial determination (as
to which all rights of appeal therefrom have been exhausted or lapsed) that
Indemnitee has engaged in acts, omissions or transactions for which Indemnitee
is prohibited from receiving indemnification under this Agreement or applicable
law.

              (b)    Claims Initiated by Indemnitee. To indemnify or make
Expense Advances to Indemnitee with respect to Claims initiated or brought
voluntarily by Indemnitee and not by way of defense, counterclaim or crossclaim,
except (i) with respect to actions or proceedings brought to establish or
enforce a right to indemnification under this Agreement or any other agreement
or insurance policy or under the Company's Certificate of Incorporation or
Bylaws now or hereafter in effect relating to Claims for Covered Events, (ii) in
specific cases if the Board of Directors has approved the initiation or bringing
of such Claim, or (iii) as otherwise required under Section 145 of


                                      -8-
<PAGE>   9
the Delaware General Corporation Law, regardless of whether Indemnitee
ultimately is determined to be entitled to such indemnification or insurance
recovery, as the case may be.

              (c)    Lack of Good Faith. To indemnify Indemnitee for any
Expenses incurred by the Indemnitee with respect to any action instituted (i) by
Indemnitee to enforce or interpret this Agreement, if a court having
jurisdiction over such action determines as provided in Section 13 that each of
the material assertions made by the Indemnitee as a basis for such action was
not made in good faith or was frivolous, or (ii) by or in the name of the
Company to enforce or interpret this Agreement, if a court having jurisdiction
over such action determines as provided in Section 13 that each of the material
defenses asserted by Indemnitee in such action was made in bad faith or was
frivolous.

              (d)    Claims Under Section 16(b). To indemnify Indemnitee for
expenses and the payment of profits arising from the purchase and sale by
Indemnitee of securities in violation of Section 16(b) of the Exchange Act, or
any similar successor statute; provided, however, that notwithstanding any
limitation set forth in this Section 10(d) regarding the Company's obligation to
provide indemnification, Indemnitee shall be entitled under Section 3 to receive
Expense Advances hereunder with respect to any such Claim unless and until a
court having jurisdiction over the Claim shall have made a final judicial
determination (as to which all rights of appeal therefrom have been exhausted or
lapsed) that Indemnitee has violated said statute.

       11.    Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall constitute an original.

       12.    Binding Effect; Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business or assets of the Company), spouses, heirs and
personal and legal representatives. The Company shall require and cause any
successor (whether direct or indirect, and whether by purchase, merger,
consolidation or otherwise) to all, substantially all, or a substantial part, of
the business or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place. This Agreement
shall continue in effect regardless of whether Indemnitee continues to serve as
a director, officer, employee, agent or fiduciary (as applicable) of the Company
or of any other enterprise at the Company's request.

       13.    Expenses Incurred in Action Relating to Enforcement or
Interpretation. In the event that any action is instituted by Indemnitee under
this Agreement or under any liability insurance policies maintained by the
Company to enforce or interpret any of the terms hereof or thereof, Indemnitee
shall be entitled to be indemnified for all Expenses incurred by Indemnitee with
respect to such action (including without limitation attorneys' fees),
regardless of whether Indemnitee is


                                      -9-
<PAGE>   10
ultimately successful in such action, unless as a part of such action a court
having jurisdiction over such action makes a final judicial determination (as to
which all rights of appeal therefrom have been exhausted or lapsed) that each of
the material assertions made by Indemnitee as a basis for such action was not
made in good faith or was frivolous; provided, however, that until such final
judicial determination is made, Indemnitee shall be entitled under Section 3 to
receive payment of Expense Advances hereunder with respect to such action. In
the event of an action instituted by or in the name of the Company under this
Agreement to enforce or interpret any of the terms of this Agreement, Indemnitee
shall be entitled to be indemnified for all Expenses incurred by Indemnitee in
defense of such action (including without limitation costs and expenses incurred
with respect to Indemnitee's counterclaims and cross-claims made in such
action), unless as a part of such action a court having jurisdiction over such
action makes a final judicial determination (as to which all rights of appeal
therefrom have been exhausted or lapsed) that each of the material defenses
asserted by Indemnitee in such action was made in bad faith or was frivolous;
provided, however, that until such final judicial determination is made,
Indemnitee shall be entitled under Section 3 to receive payment of Expense
Advances hereunder with respect to such action.

       14.    Notice. All notices, requests, demands and other communications
under this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and signed for by the party addressed, on the date of such
delivery, or (ii) if mailed by domestic certified or registered mail with
postage prepaid, on the third business day after the date postmarked. Addresses
for notice to either party are as shown on the signature page of this Agreement,
or as subsequently modified by written notice.

       15.    Consent to Jurisdiction. The Company and Indemnitee each hereby
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum for adjudicating such a claim.

       16.    Severability. The provisions of this Agreement shall be severable
in the event that any of the provisions hereof (including any provision within a
single section, paragraph or sentence) are held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including without limitation each portion of this Agreement containing any
provision held to be invalid, void or otherwise unenforceable, that is not
itself invalid, void or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, illegal or
unenforceable.

       17.    Choice of Law. This Agreement, and all rights, remedies,
liabilities, powers and duties of the parties to this Agreement, shall be
governed by and construed in accordance with the laws of the State of Delaware
without regard to principles of conflicts of laws.

       18.    Subrogation. In the event of payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.

       19.    Amendment and Termination. No amendment, modification, termination
or cancellation of this Agreement shall be effective unless it is in writing
signed by both the parties hereto. No waiver of any of the provisions of this
Agreement shall be deemed to be or shall constitute a waiver of any other
provisions hereof (whether or not similar), nor shall such waiver constitute a
continuing waiver.

       20.    Integration and Entire Agreement. This Agreement sets forth the
entire understanding between the parties hereto and supersedes and merges all
previous written and oral negotiations, commitments, understandings and
agreements relating to the subject matter hereof between the parties hereto.

       21.    No Construction as Employment Agreement. Nothing contained in this
Agreement shall be construed as giving Indemnitee any right to be retained in
the employ of the Company or any of its subsidiaries or affiliated entities.


       IN WITNESS WHEREOF, the parties hereto have executed this Indemnification
Agreement as of the date first above written.
