The Antibacterial Foley catheter is a silicone Foley catheter that incorporates
a broad-spectrum antibacterial agent, nitrofurazone, into the silicone matrix of
the outer and inner surfaces of the catheter in a formulation that gives
sustained release of the medication into and throughout the urethra and bladder
neck while the patient is catheterized. A clinical trial which evaluated 344
patients in acute care, intensive care and surgical settings demonstrated that
use of the Antibacterial Foley catheter yielded a three-fold reduction in the
incidence of bacterial catheter-induced urinary tract infections (" CUTI")
compared to the use of a silicone, non-medicated Foley catheter in patients who
were catheterized for one to seven days. Laboratory tests have shown the
imbedded nitrofurazone in the Antibacterial Foley catheter to inhibit the growth
of most bacteria known to cause bacterial CUTI, including some common
antibiotic-resistant strains.
 
   
The Antibacterial Foley catheter has not been cleared by the United States Food
and Drug Administration (the "FDA") or any foreign regulatory authority for
commercial distribution in the United States or elsewhere in the world and
cannot be marketed until the Company obtains such clearances. There can be no
assurance that the Antibacterial Foley catheter will be cleared by the FDA or
any foreign regulatory authority.

                                  THE COMPANY
 
    The Company develops, manufactures and markets innovative urinary continence
care products for urinary dysfunction management and urine drainage management.
The Company currently manufactures and markets a broad line of functionally and
technologically enhanced latex-free versions of standard continence care
products, including male external catheters, Foley catheters and intermittent
catheters. The Company is also developing innovative and technologically
advanced products designed to provide clinically and commercially attractive
solutions to continence care needs. The Company is conducting clinical trials
relating to the FEMSOFT insert, a soft, liquid-filled, conformable urethral
insert for managing female incontinence. In May 1997, the Company submitted a
510(k) pre-market notification (a "510(k)") to the United States Food and Drug
Administration (the "FDA") for the Antibacterial Foley catheter, which is
designed to reduce the incidence of bacterial catheter-associated urinary tract
infection ("CUTI"). The Company intends to expand the marketing and sales of
ROCHESTER MEDICAL brand products using the Company's dedicated sales force and,
simultaneously, to increase the distribution of private label products through
its existing strategic relationships. The Company believes that its proprietary
manufacturing technologies, including its liquid encapsulation techniques,
automated production processes and synthetic materials know-how, enable the
Company to manufacture products with innovative designs and features on a cost
effective basis.
 
   
    The Company's urinary dysfunction management products address the two
primary types of chronic urinary dysfunction: urinary incontinence, the
inability to control one's urinary function, leading to involuntary and frequent
urine leakage; and urinary retention, an inability to voluntarily, spontaneously
and completely empty the bladder. The Company markets a broad line of latex-free
catheters for urinary dysfunction management, including male external catheters
for male urinary incontinence and intermittent catheters for male and female
urinary retention. The Company is developing the FEMSOFT insert for managing
female stress urinary incontinence, the most common form of urinary
incontinence. In February 1997, the Company commenced a multi-site clinical
trial of the FEMSOFT insert, which will involve 120 patients over a 12 month
period. The Company has reported to the FDA preliminary clinical trial results
through July 15, 1997. These preliminary clinical trial results cover 38
patients and 2,101 patient uses and indicate that use of the FEMSOFT insert
resulted in a significant reduction of incontinence episodes and a 94% rate of
patient satisfaction, as indicated by written questionnaire responses in which
patients expressed a desire to continue use of the FEMSOFT insert. As of July
15, 1997, 11 infections, six instances of minor external tissue trauma
associated with the patients' inexperience in application of the FEMSOFT insert
during the first week of use, and five patient withdrawals from the clinical
trials had been reported. The Company will be required to file a pre-market
approval application (a "PMA") to obtain FDA approval to market the FEMSOFT
insert in the United States.
    
 
    Urinary dysfunction affects approximately 11 million women and two million
men in the United States. The consequences of urinary dysfunction, including
discomfort, depression, loss of mobility, social withdrawal and embarrassment
about appearance and odor, are significant and often result in a dramatic change
in quality of life. Urinary incontinence has medical consequences as well,
including predisposition to perineal rashes, pressure ulcers, urinary tract
infections and urosepsis. The medical consequences of urinary retention include
severe infection, kidney failure and death. Approximately $15 billion is spent
annually in the United States for the medical treatment and management of
urinary dysfunction. Of this amount, the Company estimates that $3 billion is
spent on management products, including devices,
 
                                       3
<PAGE>
catheters and absorbents, and the remainder is spent on institutionalization and
medical treatments, including surgery, pharmaceuticals and behavior therapy. To
date, available medical treatments and management products have had limited
success in continence management. In a recent survey of incontinent individuals,
survey respondents reported an overall cure rate of less than 3% for all medical
treatments, and 62% of respondents reported they were dissatisfied with their
medical treatment for urinary incontinence.
 
   
    The Company's urine drainage management products are used by medical
professionals on a temporary basis to monitor and manage urine drainage during
surgery, post-operative recovery and other forms of acute care. For urinary
drainage management, the Company markets a broad line of silicone Foley
catheters. The Company's Foley catheters are latex-free, eliminating the risk of
allergic reactions and reducing the potential for tissue damage, which can be
associated with latex use. These catheters incorporate advanced features, such
as smooth, seamless exteriors, which help to reduce the risk of irritation. The
Company is developing the Antibacterial Foley catheter, an advanced-design
catheter which provides sustained release of a broad-spectrum antibacterial
agent while the patient is catheterized. Clinical trials have demonstrated that
the Antibacterial Foley catheter provided a three-fold reduction in the
incidence of CUTI during the first seven days of catheterization, as compared to
other silicone Foley catheters. CUTI is a leading type of infection in
hospitals, resulting in approximately 900,000 infections annually in the United
States. CUTI develops in approximately 10% to 30% of patients with Foley
catheters. The cost of treating CUTI is estimated at over $600 million annually
in the United States or an average of $680 per case of CUTI.
    
 
    Through an expanded sales force, the Company intends to promote awareness of
the key advantages of ROCHESTER MEDICAL brand products, including the FEMSOFT
insert and the Antibacterial Foley catheter, relative to competitive continence
care products. The sales force will focus on differentiating the Company's
products on the basis of quality, potential improved medical outcomes and cost
effectiveness. The Company intends to increase its penetration of the continence
care market further through distribution relationships with established medical
products companies, which provide the Company with broad access to the hospital,
long-term care, home care and physician markets. The Company supplies male
external catheters and Foley catheters to the ConvaTec division of E.R. Squibb &
Sons, Inc., a subsidiary of Bristol-Myers Squibb Company ("ConvaTec"), pursuant
to a distribution and co-development arrangement. Also, the Company supplies
Hollister, Incorporated ("Hollister") with its requirements of self-adhering,
latex-free male external catheters and is a supplier to Euromedical Industries
Sdn Bhd (a subsidiary of Allegiance Health Care Corporation) ("Allegiance
Euromedical") and Mentor Corporation ("Mentor").
 
    The Company uses custom-designed and custom-built equipment, automated
program control and comprehensive performance testing to maintain product
quality. The Company recently obtained ISO 9001 certification and quality system
certification for the CE mark for its current Foley catheter and male external
catheter production lines. The Company has expanded its manufacturing facility
and is completing the installation of additional manufacturing equipment. The
Company has also constructed a new manufacturing facility to house its liquid
encapsulation manufacturing operations, including production capacity for the
FEMSOFT insert and other advanced design products. The Company believes that its
manufacturing technology is particularly well-suited to high unit volume
production and that its automated processes enable cost-effective production
through simplification and automation of traditional catheter manufacturing
techniques. The Company intends to use its proprietary capabilities in molding,
shaping and forming liquid encapsulated devices, as well as its antimicrobial
matrix and polymer and adhesive technologies, to develop other innovative
medical devices.
 
    The Company was incorporated in Minnesota in April 1988. The Company's
principal executive offices are located at One Rochester Medical Drive,
Stewartville, Minnesota 55976, and its telephone number is (507) 533-9600.

PRODUCT DEVELOPMENT RISKS; LACK OF REGULATORY APPROVAL
 
    The Company believes that its ability to increase revenues and to achieve
profitability and positive cash flow will depend, in part, upon its ability to
complete the development of, receive regulatory approval for, and successfully
market its products in development, particularly the Antibacterial Foley
catheter and FEMSOFT insert. The production and marketing of the Company's
products in development, including the Antibacterial Foley catheter and FEMSOFT
insert, and certain of the Company's ongoing research and development activities
are subject to regulation by numerous government authorities in the United
States and other countries. Neither the Antibacterial Foley catheter nor the
FEMSOFT insert has been authorized for commercial distribution in the United
States or any foreign country. Both products will require FDA authorization
before the Company may begin marketing them in the United States as well as
similar authorization from appropriate regulatory bodies in foreign
jurisdictions prior to commercialization in such jurisdictions. The process of
obtaining FDA and other domestic and foreign regulatory authorization is
unpredictable and often lengthy, and there can be no assurance that the FDA or
any other regulatory body will grant authorization for either the Antibacterial
Foley catheter or the FEMSOFT insert or any other product in a timely manner, if
at all. In May 1997, the Company submitted a 510(k) for the Antibacterial Foley
catheter to the FDA. There can be no assurance that the FDA will authorize
marketing of the Antibacterial Foley catheter, or that the FDA will not make
requests for additional information or clinical data that could result in a
significant delay in bringing the product to market. The Company intends to
submit a PMA for the FEMSOFT insert based on data to be derived from an ongoing
multi-site clinical trial. The clinical data obtained from this clinical trial
to date is preliminary. There can be no assurance that such trials when
completed will yield data that support the safety and efficacy of the FEMSOFT
insert or that such clinical trials, or continued development efforts, will not
identify significant technical, manufacturing, design or other obstacles that
could delay submitting a PMA. As a result, there can be no assurance that the
Company will submit a PMA with respect to the FEMSOFT insert in a timely manner,
if at all. If the FEMSOFT insert is not determined by the FDA to be safe and
effective, or if the Company otherwise fails to obtain FDA approval of either
the FEMSOFT insert or the Antibacterial Foley catheter, or if the Company
experiences a significant delay or unforeseen expenditure in the course of
attempting to obtain such approvals, scaling-up manufacturing, or marketing such
products, if approved, the Company could be materially adversely affected. See
"Business--Products," "--Marketing and Sales" and "--Government Regulation."
 
UNCERTAINTY OF MARKET ACCEPTANCE OF NEW PRODUCTS
 
   
    Much of the Company's ability to increase revenues and to achieve
profitability and positive cash flow will depend on the successful introduction
of its products in development, including the Antibacterial Foley catheter and
the FEMSOFT insert, which have not yet been commercially introduced and
represent new methods for urinary continence care. There can be no assurance
that these products will gain any significant degree of market acceptance among
physicians, healthcare payors and patients, even if regulatory and reimbursement
approvals are obtained. The Company believes that recommendations by physicians
and clinicians will be essential for the market acceptance of these products and
there can be no assurance that any such recommendations will be obtained. Broad
market acceptance of the Company's products in development, primarily the
FEMSOFT insert, may require the training of numerous physicians and clinicians,
and the time required to complete such training could result in a delay or
dampening of
    
 
                                       6
<PAGE>
such market acceptance. Moreover, health care payors' approval of reimbursement
for the Company's products in development will be an important factor in
establishing market acceptance. Patient acceptance of these products will depend
on many factors, including physician recommendations, the degree, rate and
severity of potential complications, the cost and benefits compared to competing
products or alternative medical treatments, lifestyle implications, available
reimbursement and other considerations. In addition, the Company has not yet
determined pricing for these products, and the Company's pricing policies could
adversely impact market acceptance of these products as compared to competing
products and alternative treatments. Any of the foregoing factors, or other
factors, could limit or detract from market acceptance of these products.
Insufficient market acceptance of these products could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business--Products and Products in Development."
 
LIMITED REVENUES; HISTORY OF LOSSES AND ANTICIPATED FUTURE LOSSES
 
   
    The Company has generated only limited revenues to date and has experienced
net losses since its inception. Net losses for the fiscal years ended September
30, 1994, 1995 and 1996 and for the nine months ended June 30, 1997 were
$964,000, $1.3 million, $1.4 million and $1.5 million, respectively. The Company
had an accumulated deficit of approximately $6.9 million at June 30, 1997. The
Company's ability to increase revenues and achieve profitability and positive
cash flow will depend in part upon the Company's ability to complete development
of, and successfully introduce, new products, particularly the Antibacterial
Foley catheter and FEMSOFT insert, of which there can be no assurance. The
Company expects to incur substantial product development, clinical research and
other expenses in connection with obtaining final regulatory approval for, and
commercialization of, the Antibacterial Foley catheter, and with the clinical
testing, development and commercialization of the FEMSOFT insert, as well as for
other new products and products in development. In addition, the Company
anticipates increased operating expenses as it expands its sales and marketing
organization. The Company will also experience additional manufacturing expenses
in connection with the ongoing expansion and scale-up of capacity at its
manufacturing facilities. A substantial portion of the expenses associated with
the expansion and scale-up of the Company's manufacturing facilities are fixed
in nature (i.e. depreciation) and will reduce the Company's operating margin
until such time, if ever, as the Company is able to increase utilization of such
expanded capacity. As a result, the Company expects to incur substantial
operating losses for the foreseeable future and there can be no assurance that
the Company will ever generate substantial revenues or achieve or sustain
profitability.
    
 
HIGHLY COMPETITIVE MARKETS; ALTERNATIVE TREATMENTS; TECHNOLOGICAL ADVANCEMENTS
 
    The medical products market in general is, and the markets for urinary
continence care products in particular are, highly competitive. The Company's
ability to compete in the urinary continence care market depends primarily on
price, product quality and features, technical capability, breadth of product
line and distribution capabilities. Many of the Company's competitors have
greater name recognition than the Company and offer well known and established
products, some of which are less expensive than the Company's products. As a
result, even if the Company can demonstrate that its products provide greater
ease of use, lifestyle improvement or beneficial effects on medical outcomes
over the course of treatment, the Company may not be successful in capturing a
significant share of the market. In addition, many of the Company's competitors
offer broader product lines than the Company, which may be a competitive
advantage in obtaining contracts with healthcare purchasing groups. The Company
relies to a large extent on distribution relationships that include the
Company's products, both those sold under private label
arrangements and those marketed under the ROCHESTER MEDICAL brand, as part of
broader product offerings. There can be no assurance, however, that the Company
will be able to maintain such relationships or that they will be successful in
inducing significant purchasers to buy the Company's products. Additionally,
many of the Company's competitors have substantially more marketing and sales
experience than the Company and substantially greater resources to devote to
such efforts. Finally, other factors within and outside the Company's control
will also affect its ability to compete, including its product development and
 
                                       7
<PAGE>
innovation capabilities, its ability to obtain required regulatory clearances,
its ability to protect the proprietary technology included in its products and
manufacturing processes, its manufacturing and marketing capabilities and its
ability to attract and retain skilled employees. There can be no assurance that
the Company will be able to compete against such competitors or against
potential competitors, or that competition in the Company's markets will not
result in pricing pressures that would adversely affect the Company's unit
prices and sales levels any of which could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
    In addition to the Company's products, urinary continence care can be
managed with a variety of alternative medical treatments and management products
or techniques, including adult diapers and absorbent pads, surgery, behavior
therapy, pelvic muscle exercise, implantable devices, injectable materials and
other medical devices. Moreover, manufacturers of products similar to the
Company's are engaged in research to develop more advanced versions of current
products. Many of the companies that are engaged in such development work have
substantially greater capital resources than the Company and greater expertise
than the Company in research, development and regulatory matters. There can be
no assurance that the Company's products will be able to compete with existing
or future alternative products, techniques or therapies, or that advancements in
existing products, techniques or therapies will not render the Company's
products obsolete. Finally, the Company's urinary dysfunction products are
management options, not a permanent cure. The development of a cure for urinary
dysfunction would have a material adverse effect on the Company's business,
financial condition, and results of operations.
 
DEPENDENCE ON DISTRIBUTION ARRANGEMENTS
 
    A significant portion of the Company's net sales to date have depended on
the Company's ability to provide products that meet the requirements of
ConvaTec, Mentor and the other medical product companies with which the Company
has private label or distribution arrangements, and on the sales and marketing
efforts of such entities. These arrangements are likely to continue to be a
significant portion of the Company's revenues in the future. Private label
arrangements with medical products companies accounted for approximately 81%,
79%, 82% and 78% of the Company's net sales for fiscal years 1994, 1995, 1996
and the nine months ended June 30, 1997, respectively. The Company will also
continue to establish distribution arrangements with third parties for ROCHESTER
MEDICAL brand products. There can be no assurance that the Company's private
label purchasers and other distributors will be able to successfully market and
sell the Company's products, that they will devote sufficient resources to
support the marketing of any of the Company's products, or that they will market
any of the Company's products at prices which will permit such products to
develop, achieve, or sustain market acceptance. The failure of the Company's
private label purchasers or other distributors to effectively market the
Company's products could have a material adverse effect on the Company's
business, financial condition and results of operations. Moreover, in addition
to the restrictions and obligations described below, the private label
agreements impose certain obligations upon the Company relating to, among
others, delivery of commercial quantities of its products, delivery of products
in accordance with specifications, the maintenance of product liability
insurance and certain indemnification obligations. The failure or inability of
the Company to comply with the terms of these agreements could permit the
Company's private label purchasers and other distributors to terminate their
respective agreements. In addition, there can be no assurance that any of these
private label purchasers or other distributors will perform its obligations
under its respective agreement with the Company. Any such termination or
abandonment could have a material adverse effect on the ability of the Company
to market and sell its products.
 
    The Company's distribution agreement with ConvaTec (the "ConvaTec
Agreement") grants ConvaTec, subject to obligations and limitations imposed by
certain of the Company's other distribution agreements, exclusive private label
rights to market, under ConvaTec brands, the Company's products that, as of the
date of the ConvaTec Agreement, were currently produced or in development. The
ConvaTec Agreement limits the Company's ability to distribute such products
through third parties other than under
 
                                       8
<PAGE>
the ROCHESTER MEDICAL brand. Although ConvaTec's rights are exclusive for
certain products on a private label basis, ConvaTec is not subject to any
minimum purchase requirements. Prior to the distribution of any products, the
Company and ConvaTec must negotiate in good faith on packaging, quality control
specifications and pricing for each of those products. The ConvaTec Agreement
also grants ConvaTec rights of first and last refusal with respect to marketing
future products, developed after the date of the ConvaTec Agreement. Currently,
the Company and ConvaTec are in discussions regarding the status of the FEMSOFT
insert under the ConvaTec Agreement. The Company's position is that the FEMSOFT
insert is subject only to ConvaTec's rights of first and last refusal, while
ConvaTec has expressed its view that ConvaTec has exclusive rights to be the
private label distributor of the device, subject to agreement on transfer
prices. If the Company and ConvaTec are unable to reach agreement, these issues
may be resolved by arbitration. There can be no assurance as to the outcome of
any such arbitration.
 
   
    The Company is also party to a private label agreement with Mentor pursuant
to which the Company grants Mentor a non-exclusive, paid-up, royalty free
license to make, use and sell the silicone external catheters that Mentor now
purchases from the Company. As a result, there can be no assurance that Mentor
will not begin to manufacture the silicone external catheter itself and
discontinue its purchase and marketing of the Company's product. Such
discontinuation could have a material adverse effect on the Company's business,
financial condition and results of operations.
    
 
    In addition, sales of the Company's products under its private label
arrangements compete with sales of the Company's ROCHESTER MEDICAL brand
products. Such competition might have an adverse effect on the Company's ability
to establish its ROCHESTER MEDICAL brand or on the Company's margins. See
"Business-- Marketing and Sales" and "--Private Label Distribution Agreements."
 
RISKS ASSOCIATED WITH MARKETING AND SALES OF ROCHESTER MEDICAL BRAND PRODUCTS
 
    To date, the Company has depended to a significant extent on marketing its
continence care products under private label arrangements and has conducted
relatively limited domestic selling and marketing activities for its ROCHESTER
MEDICAL brand. A key element of the Company's business strategy is to pursue
sales growth of its ROCHESTER MEDICAL brand products, and to develop market
recognition for the brand to support the future market introduction of the
Antibacterial Foley catheter and FEMSOFT insert, as well as other products in
development. The Company is engaged in refining market strategies for its
current ROCHESTER MEDICAL brand products and in developing market strategies for
its planned ROCHESTER MEDICAL brand products. The Company also has established a
small domestic marketing and sales organization to implement its plans. One of
the challenges facing the Company in this respect is the need to structure its
marketing efforts to address the changing nature of the domestic healthcare
market. In particular, healthcare purchasing is becoming increasingly
centralized, which may put the Company at a disadvantage compared to companies
with a wider array of products. In addition, many purchasers of urine drainage
catheters prefer to purchase such catheters packaged in a tray, which is a
single container including a catheter and related accessories, such as
collection bags. The Company does not currently offer its urine drainage
catheters in trays, which can be a competitive disadvantage with potential
customers who prefer such packaging. Although the Company may address this
disadvantage in the future by offering its own catheter trays, the Company does
not currently have any supply arrangements for tray components. There can be no
assurance that the Company will succeed in marketing its products under the
ROCHESTER MEDICAL brand, developing an effective marketing and sales force, or
adapting its marketing efforts to changes in the domestic healthcare market.
Moreover, the FEMSOFT insert, if approved by the FDA and introduced
commercially, may require the Company to undertake extensive educational efforts
directed to physicians and clinicians and significant media advertising directed
to consumers. The Company has no previous experience with such educational
efforts or consumer oriented media advertising, and there can be no assurance
that the Company will be successful in such activities. See "Business--Marketing
and Sales."
 
    The Company has entered into collaborative arrangements with a number of
distributors providing for the marketing and sale of certain of the Company's
products in various international markets. In general,
 
                                       9
<PAGE>
pursuant to these agreements, the Company is required to provide quantities of
its products for sale by its distributors, and the Company's distributors are
required to use their best efforts to market and sell the Company's products in
their respective markets. Any termination or abandonment by one or more of the
Company's distributors could have a material adverse impact on the ability of
the Company to market and sell its products. Furthermore, failure by the
Company's distributors to effectively market the Company's products in their
respective markets could have a material adverse effect on the Company. See
"Business--Marketing and Sales."
 
POSSIBLE NEED FOR ADDITIONAL CAPITAL
 
   
    The Company intends to expend substantial funds for product research and
development, expansion of sales and marketing activities, expansion of
manufacturing capacity, product education efforts, advertising and other working
capital and general corporate purposes. Although the Company believes that the
net proceeds of this offering, together with its existing resources and
anticipated cash flows from operations, will be sufficient to satisfy its
capital needs for at least 24 months following the offering, there can be no
assurance that the Company will not require additional financing before that
time. The Company's actual liquidity and capital requirements will depend on
numerous factors, including the timing of regulatory approvals, if any, for the
Antibacterial Foley catheter and FEMSOFT insert; the costs and timing of
expansion of sales and marketing activities; the amount of revenues from sales
of the Company's existing and new products; changes in, termination of, and the
success of, existing and new distribution arrangements; the cost of maintaining,
enforcing and defending patents and other intellectual property rights;
competing technological and market developments; developments relating to
regulatory and third party reimbursement matters; the cost and progress of the
Company's research and development efforts; and other factors. In the event that
additional financing is needed, the Company may seek to raise additional funds
through public or private financing, collaborate relationships or other
arrangements. Any additional equity financing may be dilutive to shareholders,
and debt financing, if available, may involve significant restrictive covenants.
Collaborative arrangements, if necessary to raise additional funds, may require
the Company to relinquish its rights to certain of its technologies, products or
marketing territories. Failure to raise capital when needed could have a
material adverse effect on the Company's business, financial condition and
results of operations. There can be no assurance that such financing, if
required, will be available on terms satisfactory to the Company, if at all. See
"Use of Proceeds" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
    
 
DEPENDENCE ON SINGLE OR LIMITED SOURCES OF SUPPLY
 
    The Company is dependent upon Dow Corning Corporation ("Dow Corning") and
General Electric Corporation ("GE") for raw materials used in the manufacture of
certain of its silicone products. Dow Corning is currently in bankruptcy
proceedings and there can be no assurance that Dow Corning will continue to
manufacture silicone or to supply silicone to medical device manufacturers,
including the Company. The Company is also dependent on Shell Chemical Company
("Shell") for the primary raw materials for the polymer used in manufacturing
certain of the Company's male external catheters. To date, the Company has
fulfilled its requirements for nitrofurazone, which is used in the Antibacterial
Foley catheter, through a single distributor. Although the Company is aware of
other distributors who are able to supply nitrofurazone, the Company does not
currently have arrangements for alternative supplies. If the Company were to
lose its current suppliers of any of these materials, it would be required to
identify a new supplier for that material, repeat biocompatibility testing of
its products using the raw materials from the new supplier and might be required
to seek additional regulatory clearance. The loss of any such supplier or any
significant decrease or interruption in supply could interrupt the manufacture
of the Company's products and have a material adverse effect on the Company's
business, financial condition and results of operations. Moreover, the
significance of product liability litigation to suppliers of raw materials used
in the manufacture of medical devices has caused such suppliers to carefully
evaluate the use of those raw
 
                                       10
<PAGE>
materials in certain medical devices. There can be no assurance that the
Company's suppliers might not in the future change their policies regarding raw
materials usage, or that such a change, if it occurred, might not adversely
affect production of the Company's then-current products or its product
development activities. See "Business--Sources of Supply."
 
UNCERTAINTIES ASSOCIATED WITH NEW AND EXPANDED MANUFACTURING FACILITIES
 
    The Company is completing installation of the equipment and components
necessary to equip a recently-constructed additional manufacturing facility.
This new facility, which will be devoted primarily to the manufacture of the
FEMSOFT insert, if approved, and certain other liquid encapsulation devices,
will consist, when completed, of approximately 52,000 square feet of office,
storage, manufacturing, chemical handling and clean room manufacturing space.
The Company has also recently expanded its current manufacturing facility to
increase production capacity for male external and Foley catheters, and is in
the process of installing equipment and components there. The Company has not
validated or obtained regulatory approval for either the new facility or the
expansion to the existing facility. The Company may encounter delays and
technical difficulties, along with associated cost over-runs, while installing
and testing, obtaining regulatory approval for, and beginning commercial
production on the new production lines, any of which could have a material
adverse effect on the Company. Additionally, there can be no assurance that the
new facilities will enable the Company to produce the quantities of products
required for commercialization in the United States and abroad. The inability to
produce products in such quantities or to utilize such new capacity fully, if,
for example, the FEMSOFT insert is not successfully developed, authorized by the
FDA and marketed, could have a material adverse effect on the Company. See
"Business--Properties."
 
EFFECTS OF GOVERNMENT REGULATION
 
    The Company's products, product development activities and manufacturing
processes are subject to extensive regulation by the FDA and by comparable
agencies in foreign countries. In the United States, the FDA regulates the
introduction of medical devices as well as manufacturing, labeling and record
keeping procedures for such products. The process of obtaining marketing
clearance for new medical products from the FDA can be costly and time
consuming, and there can be no assurance that such clearance will be granted for
the Company's future products on a timely basis, if at all, or that FDA review
will not involve delays that would adversely affect the Company's ability to
commercialize additional products or to expand permitted uses of existing
products. Even if regulatory clearance to market a product is obtained from the
FDA, this clearance may entail limitations on the indicated uses of the product.
Marketing clearance can also be withdrawn by the FDA due to failure to comply
with regulatory standards or the occurrence of unforeseen problems following
initial clearance. The Company may be required to make further filings with the
FDA under certain circumstances, such as the addition of product claims or
product reformulation. The FDA could also limit or prevent the manufacture or
distribution of the Company's products and has the power to require the recall
of such products. FDA regulations depend heavily on administrative
interpretation, and there can be no assurance that future interpretation made by
the FDA or other regulatory bodies, which may have retroactive effect, will not
adversely affect the Company. The FDA and various state agencies inspect the
Company and its facilities from time to time to determine whether the Company is
in compliance with regulations relating to medical device manufacturing
companies, including regulations concerning manufacturing, testing, quality
control and product labeling practices. A determination that the Company is in
material violation of such regulations could lead to the imposition of civil
penalties, including fines, product recalls, product seizures, or, in extreme
cases, criminal sanctions. See "Business--Government Regulation."
 
    A portion of the Company's revenues are dependent upon sales of its products
outside the United States. Foreign regulatory bodies have established varying
regulations governing product standards, packaging requirements, labeling
requirements, import restrictions, tariff regulations, duties and tax
 
                                       11
<PAGE>
requirements. The Company relies on its third-party foreign distributors to
comply with certain foreign regulatory requirements. The inability or failure of
the Company or such foreign distributors to comply with varying foreign
regulations or the imposition of new regulations could restrict the sale of the
Company's products internationally and thereby adversely affect the Company's
business, financial condition and results of operations. See
"Business--Government Regulation."
 
DEPENDENCE ON THIRD PARTY REIMBURSEMENT
 
    The Company's products are purchased by hospitals and other users, which
bill various third party payors, such as government health programs, private
health insurance plans, managed care organizations and other similar programs,
for the health care products and services provided to their patients. Payors may
deny reimbursement if they determine that a product used in a procedure was not
used in accordance with established payor protocols regarding cost-efficient
treatment methods, was used for an unapproved indication or was not otherwise
covered. Third party payors are increasingly challenging the prices charged for
medical products and services and, in some instances, have pressured medical
suppliers to lower their prices. The Company is unable to predict what changes
will be made in the reimbursement methods used by third party health care
payors. There can be no assurance that treatments utilizing the Company's
products will be considered cost effective by third party payors, that
reimbursement for such treatments will be available or, if available, that payor
reimbursement levels will not adversely affect the Company's ability to sell its
products on a profitable basis. Moreover, Medicare, Medicaid and private third
party payors may limit reimbursement for disposable devices such as those
manufactured by the Company by implementing fee schedules or by allowing
reimbursement for only a fixed number of devices per month. In addition,
healthcare costs have risen significantly over the past decade, and there have
been and may continue to be proposals by legislators, regulators and third party
payors to curb these costs. The Company is currently unable to assess the
eligibility of the FEMSOFT insert for reimbursement. Failure by users of the
Company's products to obtain reimbursement from third party payors, changes in
third party payors' policies towards reimbursement for the Company's products or
legislative action limiting reimbursement for certain procedures or products
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Third Party Reimbursement."
 
DEPENDENCE ON PATENTS AND PROPRIETARY RIGHTS
 
   
    The Company's success may depend in part on its ability to obtain patent
protection for its products and manufacturing processes, to preserve its trade
secrets, and to operate without infringing the proprietary rights of third
parties. The validity and breadth of claims covered in medical technology
patents involve complex legal and factual questions and, therefore, may be
highly uncertain. No assurance can be given that the scope of any patent
protection under the Company's current patents, or under any patent the Company
might obtain in the future, will exclude competitors or provide competitive
advantages to the Company; that any of the Company's patents will be held valid
if subsequently challenged; or that others will not claim rights in or ownership
of the patents and other proprietary rights held by the Company. The Company is
aware that others, including UroMed Corporation ("UroMed"), a manufacturer of a
urethral insert, have obtained or are pursuing patent protection for various
aspects of the design, production and manufacturing of continence care products.
There can be no assurance that the Company's technology, current or future
products or activities will not be deemed to infringe upon the rights of others,
including but not limited to UroMed. Furthermore, there can be no assurance that
others have not developed or will not develop similar products or manufacturing
processes, duplicate any of the Company's products or manufacturing processes,
or design around the Company's patents. The Company also relies upon unpatented
trade secrets to protect its proprietary technology, and no assurance can be
given that others will not independently develop or otherwise acquire
substantially equivalent technology or otherwise gain access to the Company's
proprietary technology or disclose such technology or that the Company can
ultimately protect meaningful rights to such unpatented proprietary technology.
    
 
                                       12
<PAGE>
   
    The medical device industry is characterized by frequent and substantial
intellectual property litigation, particularly with respect to newly developed
technology. Litigation may be necessary to enforce patents issued to the
Company, to protect trade secrets or know-how owned by the Company, or to
determine the ownership, scope or validity of the proprietary rights of the
Company and others. The Company has received an opinion from patent counsel to
the effect that the FEMSOFT insert as configured, as of the date of the opinion,
does not infringe a United States patent held by UroMed. The opinion only
represents the reasoned professional judgment of the Company's patent counsel
and is not binding on any court or third party. This opinion of patent counsel
would not preclude an action for patent infringement by UroMed, and UroMed could
choose to bring an action alleging infringement of the UroMed patent at any time
in the future. Intellectual property litigation is complex and expensive, and
the outcome of such litigation is difficult to predict. Any such litigation,
regardless of outcome, could result in substantial expense to the Company and
significant diversion of the efforts of the Company's technical and management
personnel. As a result, a claim by a third party that the Company's current
products or products in development allegedly infringe its patent rights could
have a material adverse effect on the Company. Moreover, an adverse
determination in any such proceeding could subject the Company to significant
liabilities to third parties, require disputed rights to be licensed from such
parties, if licenses to such rights could be obtained, and/or require the
Company to cease using such technology. If third party patents containing claims
affecting the Company's technology were issued and such claims were determined
to be valid, there can be no assurance that the Company would be able to obtain
licenses to such patents at costs reasonable to the Company, if at all, or be
able to develop or obtain alternate technology. Accordingly, an adverse
determination in a judicial or administrative proceeding or failure to obtain
necessary licenses could prevent the Company from manufacturing, using or
selling certain of its products, which could have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Business--Patents and Proprietary Rights."
    
 
POSSIBILITY OF PRODUCT LIABILITY LITIGATION; POSSIBLE INADEQUACY OF INSURANCE
 
    The medical products industry is subject to substantial product liability
litigation, and the Company 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. Although the Company has not
experienced any product liability claims to date, any such claims could have a
material adverse effect on the Company, including on market acceptance of its
products. The Company maintains general insurance policies that include coverage
for product liability claims. The policies are limited to an aggregate maximum
of $6 million per product liability claim, with an annual aggregate limit of $6
million under the policies. The Company may require increased product liability
coverage as new products are developed and commercialized. There can be no
assurance that liability claims will not exceed the coverage limits of the
Company's policies or that adequate insurance will continue to be available on
commercially reasonable terms, if at all. A product liability claim or other
claim with respect to uninsured liabilities or in excess of insured liabilities
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company is dependent upon Anthony J. Conway, the Company's Chief
Executive Officer and President, and upon Philip J. Conway and Richard D. Fryar,
Vice Presidents of the Company, who together perform the substantial majority of
the Company's research and development efforts as well as perform various
management functions. Additionally, the Company is dependent on the services of
Brian J. Wierzbinski, the Company's Chief Financial Officer, as well as on the
services of certain of the Company's marketing and sales personnel. The Company
also depends on its ability to attract and retain additional highly qualified
management and technical personnel. Additionally, the Company's future success
depends on its ability to attract and retain skilled and unskilled production
personnel in accordance with future sales volumes. The Company faces intense
competition for qualified personnel in all of the
 
                                       13
<PAGE>
aforementioned areas, and there can be no assurance that the Company will be
able to attract and retain such personnel. The loss of the services of one or
more of the current management group or the inability to hire additional
personnel as needed could impair the Company's ability to commercialize and
manufacture its products or to develop new products and could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Management."
 
FLUCTUATIONS IN QUARTERLY FINANCIAL PERFORMANCE
 
    The Company may experience significant fluctuations in revenues and results
of operations on a quarter to quarter basis in the future. Quarterly operating
results may fluctuate due to numerous factors, including the timing of
regulatory approvals, if any, of the Antibacterial Foley catheter and FEMSOFT
insert, the timing and level of market acceptance, if any, of the Antibacterial
Foley catheter and FEMSOFT insert, the timing and level of expenditures
associated with new product development activities, the timing and level of
expenditures associated with expansion of sales and marketing activities and
overall operations, the Company's ability to cost-effectively expand
manufacturing capacity and maintain consistently acceptable yields in the
manufacture of continence care products, the success of the activities conducted
under private label arrangements, changes in demand for the Company's products
based on changes in third party reimbursement, competition, changes in
government regulation and other factors, the timing of significant orders from
and shipments to customers, and general economic conditions. These factors are
difficult to forecast, and these or other factors could have a material adverse
effect on the Company's business, financial condition and results of operations.
Fluctuations in quarterly demand for products and order cancellations may
adversely affect the continuity of the Company's manufacturing operations,
increase uncertainty in operational planning, disrupt cash flow from operations
and contribute to the volatility of the Company's stock price. The Company's
expenses are based in part on the Company's expectations as to future revenue
levels and to a large extent are fixed in the short-term. If actual revenues do
not meet expectations, the Company's business, financial condition and results
of operations could be materially adversely affected. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Potential Fluctuations in Quarterly Results."
 
POTENTIAL VOLATILITY OF STOCK PRICE
 
    In recent years, the stock markets have experienced price and volume
fluctuations that have particularly affected medical technology companies,
resulting in changes in the market prices of the stocks of many companies which
may not have been directly related to the operating performance of those
companies. Factors such as variations in the Company's financial performance,
changes in stock market analysts' recommendations regarding the Company,
announcements of technological innovations by the Company, its competitors or
providers of alternative products, therapies or results of clinical trials or
other regulatory or reimbursement developments relating to the Company could
cause the market price of the Common Stock to fluctuate substantially. Broad
market fluctuations, or other factors affecting the market prices of the stocks
of medical technology companies generally, may adversely affect the market price
of the Common Stock.
 
POSSIBLE ISSUANCES OF PREFERRED STOCK; ANTI-TAKEOVER EFFECTS OF MINNESOTA LAW
 
    Pursuant to the Company's Articles of Incorporation, the Board of Directors
has the authority to fix the rights, preferences, privileges and restrictions,
including voting rights, of unissued shares of the Company's capital stock and
to issue such stock without any further vote or action by the shareholders. The
rights of the holders of the Common Stock will be subject to, and may be
adversely affected by, the rights of the holders of any preferred stock that may
be created and issued in the future. The issuance of preferred stock could have
the effect of delaying, deferring or preventing a change in control of the
Company. In addition, certain provisions of Minnesota law applicable to the
Company could have the effect of discouraging certain attempts to acquire the
Company, which could deprive the Company's
 
                                       14
<PAGE>
shareholders of opportunities to sell their shares of Common Stock at prices
higher than prevailing market prices and may also have a depressive effect on
the market price of the Common Stock. See "Description of Capital Stock."
 
ABSENCE OF DIVIDENDS
 
    The Company has never paid any cash dividends on the Common Stock and does
not anticipate paying cash dividends in the foreseeable future. See "Dividend
Policy."
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
   
    Purchasers of the shares of Common Stock offered hereby will experience
immediate and substantial dilution in net tangible book value per share of
$10.55. Investors may also experience additional dilution as a result of the
exercise of outstanding stock options and warrants. See "Dilution."

                                USE OF PROCEEDS
 
   
    The net proceeds to the Company from the sale of the 1,300,000 shares of
Common Stock offered hereby are estimated to be $21.1 million, based on an
assumed offering price of $17.63 per share, after deducting the estimated
Placement Agent's fee and estimated offering expenses.
    
 
    The Company intends to use the net proceeds, in part, as follows: $4.0
million for development and commercialization of the Antibacterial Foley
catheter and FEMSOFT insert; $4.0 million for expansion of the ROCHESTER MEDICAL
brand sales force; $3.0 million for scale-up of manufacturing facilities; and
$3.0 million for research and development. The Company intends to use the
remainder of the net proceeds for working capital and other general corporate
purposes. In addition, the Company may use a portion of net proceeds for the
acquisition of businesses, technologies and products that complement the
Company's business. The Company currently has no commitments or agreements with
respect to any future acquisitions. Pending use as described above, the net
proceeds from this offering will be invested in short-term, interest-bearing,
investment grade securities.
 
    The amounts above are estimates, and the actual cost, timing and amount of
funds required for such uses by the Company will depend on, among other things,
the timing of regulatory approvals, if any, for the Antibacterial Foley catheter
and FEMSOFT insert; the costs and timing of expansion of sales and marketing
activities; the amount of revenues from sales of the Company's existing and new
products; changes in, termination of, and the success of, existing and new
distribution arrangements; the cost of maintaining, enforcing and defending
patents and other intellectual property rights; competing technological and
market developments; developments relating to regulatory and third party
reimbursement matters; the cost and progress of the Company's research and
development efforts; and other factors. The Board of Directors has broad
discretion in determining how the proceeds of this offering will be applied.
Based upon its current plans, the Company believes that the net proceeds of this
offering, together with its existing resources and anticipated cash flows from
operations, will be adequate to satisfy its capital needs for at least 24 months
following the offering. See "Risk Factors--Possible Need for Additional
Capital," "Special Note Regarding Forward-Looking Statements" and "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."

                                    DILUTION
 
   
    The net tangible book value of the Company as of June 30, 1997 was $17.5
million, or $4.22 per share. Net tangible book value per share represents total
tangible assets less total liabilities divided by the number of shares of Common
Stock outstanding. Without taking into account any changes in net tangible book
value after June 30, 1997, other than to give effect to the repayment of the
ConvaTec Debt, including interest thereon, for $3.7 million on September 30,
1997, and the receipt of the net proceeds from the sale of 1,300,000 shares of
Common Stock offered hereby at an assumed public offering price of $17.63 per
share, the pro forma net tangible book value of the Company as of June 30, 1997,
would have been $38.5 million, or $7.08 per share. This represents an immediate
increase in pro forma net tangible book value of $2.86 per share to existing
holders of Common Stock and immediate dilution of $10.55 per share to investors
purchasing shares of Common Stock in the offering. The following table
illustrates this per share dilution as of June 30, 1997:

</TABLE>
 
NINE MONTH PERIOD ENDED JUNE 30, 1997 COMPARED TO NINE MONTH PERIOD ENDED JUNE
  30, 1996
 
    NET SALES.  Net sales increased 46% to $5.5 million for the nine months
ended June 30, 1997, from $3.8 million for the comparable nine months of the
prior year. Progressive growth in branded product sales and sales to ConvaTec
accounted for the increase. Sales of ROCHESTER MEDICAL brand products grew at a
rate of 72% during the nine months ended June 30, 1997, compared to the
corresponding period of fiscal 1996, while sales to ConvaTec grew at the rate of
349% for the same period. Other private label sales, inclusive of sales to
Mentor, were relatively flat for the period. Sales to ConvaTec, Hollister,
Allegiance Euromedical and Mentor accounted, respectively, for 28%, 9%, 4%, and
31% of sales for the nine months ended
 
                                       21
<PAGE>
June 30, 1997, compared, respectively, to 9%, 14%, 22%, and 25% of sales for the
corresponding period of fiscal 1996.
 
   
    GROSS MARGIN.  The Company's gross margin as a percentage of net sales was
37% for the nine months ended June 30, 1997 compared with 31% for the nine
months ended June 30, 1996. Year to date margins have benefitted from
manufacturing efficiencies associated with higher production volumes. The
Company expects gross margin to be reduced in future periods by depreciation and
other expenses associated with the expansion and scale-up of the Company's
manufacturing facilities. The Company expects to experience reduced gross margin
until such time, if ever, as the Company is able to increase utilization of the
expanded and scaled-up manufacturing facilities.
    
 
    MARKETING AND SELLING.  Marketing and selling expense increased 66% to $1.6
million for the nine months ended June 30, 1997 from $941,000 for the nine
months ended June 30, 1996. The increased expense reflects expansion of the
Company's domestic field sales force and increased product promotion spending.
 
    RESEARCH AND DEVELOPMENT.  Research and development expense increased 40% to
$1.1 million for the nine months ended June 30, 1997 from $820,000 for the nine
months ended June 30, 1996, due to incremental costs associated with clinical
studies of the FEMSOFT insert.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expense increased
67% to $1.1 million for the nine months ended June 30, 1997 from $660,000 for
the nine months ended June 30, 1996, due to requirements for business and
administrative infrastructure development to support current and anticipated
growth.
 
    INTEREST INCOME (EXPENSE), NET.  Interest income decreased to $531,000 for
the nine months ended June 30, 1997 from $590,000 for the nine months ended June
30, 1996, as a result of earnings on lower levels of cash available for
investment. Interest expense remained constant for the nine month period. The
interest expense relates to the ConvaTec Debt.
 
FISCAL YEAR ENDED SEPTEMBER 30, 1996 COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30,
  1995
 
    NET SALES.  Net sales increased 77% to $5.5 million in fiscal 1996 from $3.1
million in fiscal 1995, due to increased sales in both private label and
ROCHESTER MEDICAL brand product lines. Private label sales increased 83% due to
stronger order volumes from Mentor and Allegiance Euromedical, as well as growth
from initial sales under the ConvaTec strategic alliance. A portion of 1996
sales volumes to Mentor represented inventory replenishment. Sales to ConvaTec,
Hollister, Allegiance Euromedical and Mentor accounted, respectively, for 12%,
12%, 19% and 29% of fiscal 1996 net sales compared, respectively, to 5%, 25%,
19% and 14% of fiscal 1995 net sales.
 
    GROSS MARGIN.  The Company's gross margin as a percentage of net sales
improved to 32% in fiscal 1996, compared to 22% for fiscal 1995, due primarily
to efficiencies gained through increasing production volumes and labor
productivity. Additionally, certain nonrecurring costs were incurred in fiscal
1995 for product reformulation and litigation settlement.
 
    MARKETING AND SELLING.  Marketing and selling expenses increased 57% to $1.4
million in fiscal 1996 from $858,000 in fiscal 1995. The increased expense
levels reflect overall increases in marketing and selling activities for
ROCHESTER MEDICAL brand products, including the addition of a Vice President of
International Sales, recruiting and employee relocation costs, commissions on
incremental ROCHESTER MEDICAL brand sales and other marketing and sales
activities to establish and expand the ROCHESTER MEDICAL brand. These activities
include customer service and support, direct marketing, attendance at trade
shows, product samples and other promotional programs.

<PAGE>
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased 230%
to $1.2 million in fiscal 1996 from $358,000 in fiscal 1995, due to expanded
clinical testing activities, the addition of a Director of Clinical and
Regulatory Affairs position, and funding requirements for new product
development. During fiscal 1996, the Company completed a major clinical study
for the Antibacterial Foley catheter and initiated a major clinical study for
the FEMSOFT insert.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
45% to $1.1 million in fiscal 1996 from $766,000 in fiscal 1995, due to the
addition of a Chief Financial Officer, project costs for implementation of new
business systems, and the CE mark/ISO certification process, and additional
administrative personnel and professional fees associated with general business
development.
 
    INTEREST INCOME (EXPENSE), NET.  Interest income increased to $818,000 in
fiscal 1996 from $56,000 in fiscal 1995, due to the increase in the average
balance of marketable securities purchased with the proceeds from the Company's
public offering in November 1995. Interest expense increased to $285,000 in
fiscal 1996 from $68,000 in fiscal 1995, due to interest on the ConvaTec Debt
for an entire year.
 
FISCAL YEAR ENDED SEPTEMBER 30, 1995 COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30,
  1994
 
    NET SALES.  Net sales increased 43% to $3.1 million in fiscal 1995 from $2.2
million in fiscal 1994, primarily due to increased private label sales of Foley
catheters and from higher sales of ROCHESTER MEDICAL brand products. Private
label sales increased 39% in fiscal 1995, primarily as a result of increased
sales of Foley catheters to Allegiance Euromedical, partially offset by
decreased sales of silicone male external catheters to Mentor. Sales of
ROCHESTER MEDICAL brand products increased 60% in fiscal 1995 due to higher
sales of ULTRAFLEX male external catheters and Foley catheters.
 
    GROSS MARGIN.  The Company's gross margin as a percentage of net sales was
22% in fiscal 1995 compared with 22% in fiscal 1994. The Company's gross margin
in 1995 benefitted from manufacturing efficiencies resulting from higher
production volumes, which were offset by the effect of the sale of silicone male
external catheters to Mentor in settlement of certain litigation, by a write off
of $100,000 for potential inventory obsolescence related to silicone male
external catheters and by increased raw material costs and overhead expenses.
The Company also incurred development and increased production expenses during
fiscal 1995 related to a reformulation of its ULTRAFLEX polymer necessitated by
raw material shortages due to a fire at a supplier's manufacturing facility.
 
    MARKETING AND SELLING.  Marketing and selling expenses increased 49% to
$858,000 in fiscal 1995 from $574,000 in fiscal 1994. These increased expenses
primarily reflect the addition of an Executive Vice President and two additional
sales representatives, engaging independent manufacturer's representatives and
increasing marketing and sales efforts to establish and expand the ROCHESTER
MEDICAL brand, including direct marketing and customer service, attendance at
trade shows and product sample programs.
 
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased 70%
to $358,000 in fiscal 1995 from $210,000 in fiscal 1994, due primarily to
increased clinical testing expenses for the Antibacterial Foley catheter and
continuing development of the Company's liquid encapsulated devices.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
11% to $766,000 in fiscal 1995 from $692,000 in fiscal 1994, primarily due to
write-offs in fiscal 1995 of $215,000 of accounts receivable in settlement of
certain litigation, offset in part by a decrease in legal expenses.
 
    INTEREST INCOME (EXPENSE), NET.  Interest income decreased 28% to $56,000 in
fiscal 1995 from $78,000 in fiscal 1994, due to a reduction in the average
balance of marketable securities held by the Company. Interest expense increased
75% to $68,000 in fiscal 1995 from $39,000 in fiscal 1994, due to higher
interest rates on the Company's mortgage loan and the accrual of interest on the
ConvaTec Debt.

POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS
 
    The Company may experience significant fluctuations in revenues and results
of operations on a quarter to quarter basis in the future. Quarterly operating
results will fluctuate due to numerous factors, including the timing of
regulatory approvals, if any, of the Antibacterial Foley catheter and FEMSOFT
insert, the timing and level of market acceptance, if any, of the Antibacterial
Foley catheter and FEMSOFT insert, the timing and level of expenditures
associated with new product development activities, the timing and level of
expenditure associated with expansion of sales and marketing activities and
overall operations, the Company's ability to cost-effectively expand
manufacturing capacity and maintain consistently acceptable yields in the
manufacture of continence care products, the success of the activities conducted
under private label arrangements, changes in demand for the Company's products
based on changes in third party reimbursement, competition, changes in
government regulation and other factors, the timing of significant orders from
and shipments to customers, and general economic conditions. These factors are
difficult to forecast, and these or other factors could have a material adverse
effect on the Company's business, financial condition and results of operations.
Fluctuations in quarterly demand for products and order cancellations may
adversely affect the continuity of the Company's manufacturing operations,
increase uncertainty in operational planning, disrupt cash flow from operations
and contribute to the volatility of the Company's stock price. The Company's
expenses are based in part on the Company's expectations as to future revenue
levels and to a large extent are fixed in the short-term. If actual revenues do
not meet expectations, the Company's business, financial condition and results
of operations could be materially adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
    The Company has financed its operations primarily through public offerings
and private placements of its equity securities, and has raised approximately
$24.7 million in net proceeds from its inception through June 30, 1997. In
August 1995, the Company received $3.0 million of proceeds from the issuance of
the ConvaTec Debt. The Company repaid the ConvaTec Debt, including accrued
interest, for $3.7 million on September 30, 1997. The Company has incurred an
accumulated deficit of approximately $6.9 million through June 30, 1997.
    
 
    The Company's cash and marketable securities at June 30, 1997 were $11.1
million compared to $17.4 million at September 30, 1996, a net decrease of $6.4
million. The Company used $1.1 million of cash to fund operating activities
during the nine months ended June 30, 1997 and $893,000 to fund operating
activities during fiscal 1996.
 
    Cash of $5.5 million was used for capital expenditures during the nine
months ended June 30, 1997, relating to expansion of the existing production
facility and construction of the Company's new production and administrative
facility. At June 30, 1997, the Company had commitments for $3.5 million of
capital expenditures, primarily relating to new production facilities.
 
    Trade accounts receivable at June 30, 1997 decreased 15% to $1.3 million as
compared to September 30, 1996, reflecting an increased focus on collection
activities. Inventories increased 28% to $1.5 million as compared to September
30, 1996, reflecting anticipated future sales. Changes in other asset and
liability balances relate primarily to timing of expense recognition, including
an increase of $300,000 of accrued clinical project costs.
    The Company intends to expend substantial funds for product research and
development, expansion of sales and marketing activities, expansion of
manufacturing capacity, product education efforts, advertising and other working
capital and general corporate purposes. Although the Company believes that the
net proceeds of this offering, together with its existing resources and
anticipated cash flows from operations, will be sufficient to satisfy its
capital needs for at least 24 months following the offering, there can be no
assurance that the Company will not require additional financing before that
time. The Company's actual liquidity and capital requirements will depend upon
numerous factors, including the timing of regulatory
 
                                       24
<PAGE>
approvals, if any, for the Antibacterial Foley catheter and FEMSOFT insert; the
costs and timing of expansion of sales and marketing activities; the amount of
revenues from sales of the Company's existing and new products; changes in,
termination of, and the success of, existing and new distribution arrangements;
the cost of maintaining, enforcing and defending patents and other intellectual
property rights; competing technological and market developments; developments
related to regulatory and third party reimbursement matters; the cost and
progress of the Company's research and development efforts; and other factors.
In the event that additional financing is needed, the Company may seek to raise
additional funds through public or private financing, collaborative
relationships or other arrangements. Any additional equity financing may be
dilutive to shareholders, and debt financing, if available, may involve
significant restrictive covenants. Collaborative arrangements, if necessary to
raise additional funds, may require the Company to relinquish its rights to
certain of its technologies, products or marketing territories. Failure to raise
capital when needed could have a material adverse effect on the Company's
business, financial condition and results of operations. There can be no
assurance that such financing, if required, will be available on terms
satisfactory to the Company, if at all.
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
    In June 1997, the Financial Accounting Standards Board ("FASB") issued FASB
Statement No. 130 "Reporting Comprehensive Income," which establishes standards
for the reporting and display of comprehensive income and its components in the
financial statements. The FASB also issued FASB Statement No. 131, "Disclosures
about Segments of an Enterprise and Related Information," which significantly
changes the way segment information is reported in annual financial statements
and also requires selected segment information in interim financial reports to
shareholders. Both statements are effective for fiscal years beginning after
December 15, 1997 and, based on current circumstances, the Company does not
believe the effect of adoption will be material to the financial statements.

INTRODUCTION
 
    The Company develops, manufactures and markets innovative urinary continence
care products for urinary dysfunction management and urine drainage management.
The Company currently manufactures and markets a broad line of functionally and
technologically enhanced latex-free versions of standard continence care
products, including male external catheters, Foley catheters and intermittent
catheters. The Company is also developing innovative and technologically
advanced products designed to provide clinically and commercially attractive
solutions to continence care needs. The Company is conducting clinical trials
relating to the FEMSOFT insert, a soft, liquid-filled, conformable urethral
insert for managing female incontinence. In May 1997, the Company submitted a
510(k) to the FDA for the Antibacterial Foley catheter, which is designed to
reduce the incidence of bacterial CUTI. The Company intends to expand the
marketing and sales of ROCHESTER MEDICAL brand products using the Company's
dedicated sales force and, simultaneously, to increase the distribution of
private label products through its existing strategic relationships. The Company
believes that its proprietary manufacturing technologies, including its liquid
encapsulation techniques, automated production processes and synthetic materials
know-how, enable the Company to manufacture products with innovative designs and
features on a cost effective basis.
 
   
    The Company's urinary dysfunction management products address the two
primary types of chronic urinary dysfunction: urinary incontinence, the
inability to control one's urinary function, leading to involuntary and frequent
urine leakage; and urinary retention, an inability to voluntarily, spontaneously
and completely empty the bladder. The Company markets a broad line of latex-free
catheters for urinary dysfunction management, including male external catheters
for male urinary incontinence and intermittent catheters for male and female
urinary retention. The Company is developing the FEMSOFT insert for managing
female stress urinary incontinence, the most common form of urinary
incontinence. In February 1997, the Company commenced a multi-site clinical
trial of the FEMSOFT insert, which will involve 120 patients over a 12 month
period. The Company has reported to the FDA preliminary clinical trial results
through July 15, 1997. These preliminary clinical trial results cover 38
patients and 2,101 patient uses and indicate that use of the FEMSOFT insert
resulted in a significant reduction of incontinence episodes and a 94% rate of
patient satisfaction, as indicated by written questionnaire responses in which
patients expressed a desire to continue use of the FEMSOFT insert. As of July
15, 1997, 11 infections, six instances of minor external tissue trauma
associated with the patients' inexperience in application of the FEMSOFT insert
during the first week of use, and five patient withdrawals from the clinical
trials had been reported. The Company will be required to file a PMA to obtain
FDA approval to market the FEMSOFT insert in the United States.
    
 
   
    The Company's urine drainage management products are used by medical
professionals on a temporary basis to monitor and manage urine drainage during
surgery, post-operative recovery and other forms of acute care. For urinary
drainage management, the Company markets a broad line of silicone Foley
catheters. The Company's Foley catheters are latex-free, eliminating the risk of
allergic reactions and reducing the potential for tissue damage, which can be
associated with latex use. These catheters incorporate advanced features, such
as smooth, seamless exteriors, which help to reduce the risk of irritation. The
Company is developing the Antibacterial Foley catheter, an advanced-design
catheter which provides sustained release of a broad-spectrum antibacterial
agent while the patient is catheterized. Clinical trials have demonstrated that
the Antibacterial Foley catheter provide a three-fold reduction in the incidence
of CUTI during the first seven days of catheterization, as compared to other
silicone Foley catheters. CUTI is a leading type of infection in hospitals,
resulting in approximately 900,000 infections annually in the United States.
CUTI develops in approximately 10% to 30% of patients with Foley catheters. The
cost of treating CUTI is estimated at over $600 million annually in the United
States or an average of $680 per case of CUTI.

THE CONTINENCE CARE MARKET
 
    URINARY SYSTEM AND CONTINENCE CARE
 
    In a normally functioning urinary system, the kidneys filter waste products
from the circulatory system, creating urine to remove the waste. Urine drains
from the kidneys into the bladder, which serves as a reservoir until emptied
through urination. Urinary continence, or the appropriate storage and release of
urine, is controlled by the bladder neck and the urinary sphincter, which
surrounds the bladder neck and urethra, acting together as a valve. As the
bladder fills, the bladder is relaxed while the urinary sphincter contracts to
prevent urination. During urination, the urinary sphincter relaxes as the
bladder contracts to evacuate urine through the bladder neck and urethra.
Urinary dysfunction may result from a malfunction of any part of the system.
Urinary continence care involves both the treatment and management of urinary
dysfunction and the temporary management of a normally functioning urinary
system during surgery, post-operative recovery and other forms of acute care.
 
    URINARY DYSFUNCTION
 
    Urinary dysfunction affects approximately 11 million women and two million
men in the United States. Urinary dysfunction can be characterized as either
incontinence or retention. Urinary incontinence is the inability to control
one's urinary function, leading to involuntary and frequent urine leakage from
the bladder. Urinary retention is the inability to voluntarily, spontaneously
and completely empty one's bladder, preventing urine flow even though the
bladder continues to fill.
 
    The consequences of urinary dysfunction, including depression, discomfort
and embarrassment about appearance and odor, are significant and often result in
a dramatic change in quality of life. Urinary dysfunction often results in loss
of self-esteem, an increased dependence on caregivers, a loss of mobility and
social withdrawal and isolation. In addition, urinary dysfunction has been
associated with a number of physical effects, including a predisposition to
perineal rashes, pressure ulcers, urinary tract infections, urosepsis, falls and
fractures. In the elderly, urinary dysfunction is a major cause of
institutionalization into a nursing home.
 
    URINARY INCONTINENCE.  Urinary incontinence may result from one or more
conditions: weakened pelvic muscles; pelvic organic prolapse; tumors or other
cancers and cancer treatments; prostate surgery; pelvic trauma; spinal cord
damage; and medications. These diverse conditions cause three primary forms of
urinary incontinence.
 
    - STRESS INCONTINENCE is the involuntary loss of urine caused by an increase
      in abdominal pressure during common activities, such as laughing,
      sneezing, coughing, lifting or even standing up. Among women, stress
      incontinence is primarily due to a weakening of the pelvic muscles caused
      by pregnancy and childbirth.
 
    - URGE INCONTINENCE is the involuntary loss of urine due to an involuntary
      bladder contraction which is associated with a strong, uncontrollable
      desire to urinate.
 
    - OVERFLOW INCONTINENCE is the involuntary loss of urine when the amount of
      urine produced exceeds the bladder's capacity.
 
    Stress incontinence or mixed stress and urge incontinence represent over 50%
of all cases of urinary incontinence and over 60% of cases among women. While
urinary incontinence is present at all ages, the prevalence of urinary
incontinence increases with age. Urinary incontinence affects more than 50% of
the more than 1.5 million nursing home residents in the United States. Among
persons older than 60 years of age, other than nursing home residents, the
prevalence of urinary incontinence ranges from 15% to 35%, with women having
twice the prevalence of men. In the population between 15 and 64 years of age,
the prevalence of urinary incontinence ranges from 1.5% to 5% of men and from
10% to 30% of women.
 
                                       27
<PAGE>
    URINARY RETENTION.  Individuals suffering from urinary retention are unable
to empty their bladders voluntarily. This condition may have serious medical
consequences, including severe infection, kidney failure and death. Urinary
retention is commonly caused by neurogenic bladder, an inability of the bladder
to contract in a normal manner to initiate voiding, and urinary tract
obstruction, a blockage of the bladder neck or urethra which prevents the normal
passage of urine. Neurogenic bladder is often a result of spinal cord injury,
diabetes, Parkinson's Disease, multiple sclerosis and other nervous system
trauma. Urinary tract obstructions are primarily due to drug side effects,
surgery and congenital abnormalities. Urinary retention patients often
experience a combination of incontinence and retention.
 
    CURRENT TREATMENTS FOR AND MANAGEMENT OF URINARY DYSFUNCTION
 
    Approximately $15 billion is spent annually in the United States for the
medical treatment and management of urinary dysfunction. Of this amount, the
Company estimates that $3 billion is spent annually on management products and
devices and the remainder is spent on institutionalization and medical
treatments, including surgery, pharmaceuticals and behavior therapies. To date,
available medical treatments and management products have had limited success in
continence management. In a recent survey of incontinent individuals, survey
respondents reported an overall cure rate of less than 3% for all medical
treatments, and 56% of respondents reported that their medical treatments
produced no improvement in, or worsened, their condition. Additionally, 62% of
respondents reported that they were dissatisfied with their medical treatment
for urinary incontinence.
 
    The primary medical treatments for urinary dysfunction management are
discussed below.
 
    BEHAVIORAL THERAPIES.  Behavioral therapies for stress incontinence include
bladder training and habit modification, pelvic muscle exercise, biofeedback and
electrical stimulation. All such therapies are used primarily to treat female
stress incontinence. Although these therapies are non-invasive and often result
in some patient improvement, they typically do not provide a complete cure for
urinary incontinence and require significant patient involvement. The success of
many behavioral therapies depends on following rigid voiding schedules and
strenuous exercise programs on a daily basis. Many patients are unable or
unwilling to comply with these schedules and programs over the long term.
 
    SURGERY.  Surgery is used primarily to treat stress incontinence and
includes artificial urinary sphincter implantations for patients with intrinsic
sphincter deficiency (the inability of the urinary sphincter to contract
sufficiently to maintain continence) and bladder neck suspension surgery to
stabilize the urethra for patients with hypermobility (a significant
displacement of the urethra during exertion, which accounts for a majority of
stress incontinence cases). These surgeries are expensive, involve risks of
failure and complications, including urinary retention, and are highly invasive,
requiring general anesthesia and several weeks or months for full recovery.
Another surgical treatment, indicated primarily for patients with intrinsic
sphincter deficiency, is the injection of urethral bulking agents into the area
around the urethra to create a mild obstruction. Although less invasive than
other surgeries, urethral bulking agents are relatively expensive, and the
procedure must be repeated periodically due to bioabsorption of the bulking
agents. In addition, surgery to treat urinary retention may be performed to
remove urethral obstructions, although these obstructions often return.
 
    PHARMACEUTICALS.  Pharmaceutical treatments primarily manage urge
incontinence by blocking involuntary bladder contractions. Pharmaceutical
treatments provide symptomatic relief rather than curing the underlying
condition and require long-term use. Drug treatments for urinary incontinence
may cause adverse effects, including drowsiness, dryness of the mouth,
dizziness, constipation and urinary retention.
 
    The primary management products for urinary dysfunction are discussed below.
 
    ABSORBENTS.  The most prevalent incontinence management products are adult
absorbents, including adult diapers and absorbent pads, either disposable or
reusable. Adult absorbents are used because they provide needed protection and
can be easily self-administered without seeing a physician. Disadvantages of
 
                                       28
<PAGE>
the adult absorbents include lack of control over urine flow and corresponding
discomfort from wetness, skin irritations and rash; embarrassment about
appearance and odor; perceived social stigma; inconvenience; and significant
compromise of freedom of lifestyle. Retail sales of adult absorbents in the
United States during 1995 were estimated to exceed $2.5 billion.
 
    FOLEY CATHETERS.  Foley catheters, or in-dwelling catheters (as more fully
described below), are used on a limited basis to manage urinary dysfunction. The
United States Department of Health and Human Services ("HHS") has reported that
more than 100,000 residents in nursing homes in the United States have long-term
Foley catheters in place to manage urinary dysfunction. The use of Foley
catheters to manage urinary dysfunction may cause urethral irritation and tissue
erosion due to catheter movement.
 
   
    The Company believes that over 90% of the Foley catheters sold worldwide are
made of latex. Although latex has certain attractive physical characteristics
and cost advantages, latex contains natural proteins and allergens that may
irritate and damage the surrounding tissue. Latex catheters may be less
comfortable to use than synthetic catheters because crystals of urine salt can
form more easily on the surface of latex catheters. These crystals can make
withdrawal of latex catheters cause painful tissue trauma, and can also result
in the development of permanent strictures (scar tissue) inside the urethra.
Healthcare providers now recognize that latex can also cause allergic reactions
that may be life-threatening for some patients. Concerns about latex allergies
among healthcare workers and the general population have also increased in
recent years. It has been reported that 10% to 15% of healthcare workers are
sensitive to latex healthcare products. As a result, healthcare institutions are
increasingly attempting to limit their workers' exposure to latex.
    
 
   
    On September 30, 1997, the FDA issued final rules that require labeling of
latex medical devices to warn of possible allergic reactions. The final rules
require that all medical devices containing natural rubber latex be labeled with
the warning "Caution: This Product Contains Natural Rubber Latex Which May Cause
Allergic Reactions." The FDA will also require the removal of all claims that
latex medical devices are hypoallergenic from the labeling of these devices.
Manufacturers have until September 30, 1998 to comply with the new rules.
    
 
    MALE EXTERNAL CATHETERS.  Male external catheters are disposable devices for
the management of male incontinence. The male external catheter consists of a
condom-like sheath that tapers into a cone and funnel. The sheath is unrolled
upon the penis and adheres by means of an adhesive, either contained as a part
of the wall of the sheath ("self-adhering") or provided by a separate strip of
adhesive tape ("tape-on"). The male external catheter drains through an attached
tube into a leg bag which is periodically emptied. Typically, the male external
catheter is removed and discarded daily. Male external catheters are designed to
be self-administered. These catheters are used primarily in home care settings
and long-term care facilities. Potential drawbacks of male external catheters
are leakage, skin irritation, inconvenience and reduced mobility. The Company
believes that approximately 75% of male external catheters sold worldwide are
made of latex, which results in many of the disadvantages associated with latex
products described above.
 
    URETHRAL INSERTS AND BLADDER NECK SUPPORT PROSTHESES.  The bladder neck and
urethra are delicate structures of mucous membranes and muscle that manage the
flow of fluids from the body. The urethra is a narrow, ribbon shaped canal,
which in females gradually twists and curves slightly from the bladder neck to
the exterior opening. As a result of the urethra's structure and sensitive
tissues, any rigid, nonconformable device that is inserted into the urethra has
the potential to distort the urethra's shape, cause muscle erosion and irritate
or damage the urethral tissues and make them more susceptible to infection.
Recently, urethral inserts and bladder neck support prostheses for female stress
incontinence have been introduced to the market. Currently marketed urethral
inserts occlude the female urethra to manage incontinence. Bladder neck support
prostheses manage incontinence by lifting the bladder neck and urethra through
pressure applied from the device in the vaginal cavity.
 
                                       29
<PAGE>
    INTERMITTENT CATHETERIZATION.  Intermittent catheterization is the preferred
management modality for patients with urinary retention. Intermittent
catheterization involves the use of a straight catheter inserted through the
urethra into the bladder to achieve voiding. Patients using intermittent
catheterization often must perform this procedure every three to six hours. This
procedure can be uncomfortable, is associated with an increased incidence of
urinary tract infection, and in some patients may result in severe urethral
irritation. As an adjunct to medical treatments, primarily behavioral therapies,
intermittent catheterization increasingly is being recommended to manage urinary
incontinence.
 
    URINE DRAINAGE MANAGEMENT
 
    During surgery, post-operative recovery and certain other acute care
settings, it is often necessary for medical professionals to monitor the flow of
urine, and manage the urinary functions, of patients with normally functioning
urinary systems. Typically, urine drainage management is accomplished by placing
a Foley catheter in these patients. HHS has reported estimates that as many as
one out of four hospital patients in acute care settings undergoes a short-term
Foley catheterization. The Company believes over 90% of such patients require a
Foley catheter for seven days or less. The Company estimates that sales of Foley
catheters and related accessories in the United States were $240 million in
1995.
 
    The Foley catheter is an in-dwelling catheter that provides continuous
drainage of the bladder. A Foley catheter consists of a tube (the "catheter
tube") with interior conduits ("lumens") and an inflatable balloon portion near
one end. The balloon end of the Foley catheter is inserted through the urethra
into the bladder. A sterile saline solution is injected into the balloon lumen
to inflate the balloon inside the bladder and prevent the catheter from being
withdrawn. Urine drains through eyelets in the tip of the catheter into the
drain lumen, which is connected by tubing to an external collection device, such
as a leg bag. A Foley catheter is inserted primarily by healthcare professionals
and is not designed for self-administration.
 
    The regular use of Foley catheterization for urinary drainage management is
associated with CUTI. CUTI is primarily caused by bacteria that migrate through
the urethra into the bladder along the outside of the catheter. The Company and
other industry sources estimate that 10% to 30% of patients with Foley catheters
develop a CUTI. Hospitals have reported that cases of CUTI account for 40% of
hospital-acquired infections, or approximately 900,000 infections each year.
CUTI prolongs patients' recovery time and increases mortality risk. The direct
cost of treating these infections is estimated at over $600 million annually in
the United States, or an average $680 per case of CUTI, which is substantially
greater than the cost of a Foley catheter. Moreover, increases in the number of
antibiotic-resistant strains of bacteria has raised the level of concern
regarding CUTI. In particular, as a result of these concerns, many physicians
are reluctant to prescribe antibiotics prophylactically to control CUTI.
 
ROCHESTER MEDICAL SOLUTIONS
 
    The Company currently manufactures and markets functionally and
technologically enhanced versions of standard continence care products,
including Foley catheters, male external catheters and intermittent catheters.
The Company is also developing innovative and technologically advanced products
designed to provide clinically and commercially attractive solutions to the
limitations of current continence care. The Company's products are designed to
advance the quality of continence care by providing improved medical outcomes on
a cost effective basis. The Company believes that its proprietary manufacturing
technologies, including its liquid encapsulation techniques, automated
production processes and synthetic materials know-how, enable the Company to
manufacture products with innovative designs and features.
 
    The Company believes that its current products and products in development,
including the Antibacterial Foley catheter and FEMSOFT insert, offer some or all
of the following benefits.
 
    - IMPROVED MEDICAL OUTCOMES.  The Company's products are designed to improve
      the medical outcome of continence care as compared to many current
      continence care devices. The Company's
 
                                       30
<PAGE>
   
      Foley catheters are designed to reduce irritation and damage to the
      urethra that can lead to infection, while its male external catheters are
      intended to reduce the incidence of tissue damage, in part through the
      Company's materials technology. The Company's soft and pliable FEMSOFT
      insert and advanced-design products are designed to reduce irritation and
      tissue erosion in the urethra by conforming to the movement of the urethra
      during normal activities. The Antibacterial Foley catheter is designed to
      reduce bacterial CUTI.
    
 
    - IMPROVED PATIENT SATISFACTION.  Each of the Company's products is designed
      to improve patient satisfaction and comfort. The Company's silicone male
      external catheters are odor-free and have greater gas permeability than
      catheters made from other materials. The Company believes these catheters
      may reduce skin irritation and increase patient comfort. In addition, the
      Company's male external catheters incorporate proprietary adhesive
      technologies, which create better adherence to the skin, reduce leakage
      and give the wearer greater confidence. The Company's liquid encapsulation
      technology enables it to produce soft, pliable devices, such as the
      FEMSOFT insert and other advanced design products, that are more
      comfortable for the patient to use. In addition, the FEMSOFT insert
      requires no collection bags or absorbent pads or liners, which can cause
      embarrassment, restrict mobility and compromise lifestyle.
 
    - ELIMINATION OF RISK OF LATEX REACTIONS.  The Company manufactures all of
      its products from silicone, a non-toxic, biocompatible and hypoallergenic
      material, or other non-latex synthetic materials, thereby eliminating the
      risk of latex reactions in patients and caregivers. The use of non-latex
      materials in the Company's products also protects against the irritation
      and discomfort that is sometimes associated with the use of latex-based
      products.
 
    - EASE OF USE.  The Company's self-administered products are designed to be
      easy to use and convenient for the patient. The Company's male external
      catheters are transparent, permitting visual skin inspection without
      removal of the catheters and aiding proper placement of the catheters. The
      FEMSOFT insert is designed to be easily inserted and removed by most women
      following proper training. It requires no inflation, deflation, syringes
      or valving mechanisms.
 
    - COST EFFECTIVENESS.  The Company has designed its products to include
      features intended to reduce the incidence of tissue trauma or other
      adverse consequences of continence care, which may increase the total cost
      of patient treatment. The Company believes that these features position
      its products as cost effective alternatives for patients and caregivers.
      For example, the Company believes that the Antibacterial Foley catheter
      will lower overall patient costs by reducing the incidence of bacterial
      CUTI among the relevant patient population.
 
    - QUALITY.  The Company seeks to manufacture quality continence care
      products using superior materials, program controlled production
      processes, comprehensive quality control testing and innovative product
      designs.
 
BUSINESS STRATEGY
 
    The Company's objective is to become a leading developer and worldwide
marketer of innovative continence care products of high quality and value. The
Company's strategy is to offer a broad range of continence care products,
including products for urinary dysfunction management and urinary drainage
management. Key elements of the Company's business strategy include:
 
    - FOCUS ON COMMERCIALIZING ANTIBACTERIAL FOLEY CATHETER AND FEMSOFT
      INSERT.  The Company is focused on manufacturing scale-up and marketing
      and sales preparation for introduction of the Antibacterial Foley
      catheter, if the Company receives clearance from the FDA. The Company is
      also focused on continuing clinical testing of the FEMSOFT insert in
      preparation for submitting a PMA to the FDA, and is installing a
      production line for the FEMSOFT insert and other liquid encapsulation
      products. Once these product development programs are completed, the
      Company intends to
 
                                       31
<PAGE>
      increase its focus on the development and commercialization of the
      Company's other advanced design products.
 
    - AGGRESSIVELY PURSUE SALES GROWTH OF ROCHESTER MEDICAL BRAND PRODUCTS.  To
      date, the majority of the Company's sales have been made through private
      label arrangements. The Company's strategy is to place increased emphasis
      on promotion of ROCHESTER MEDICAL brand products in order to develop
      market recognition of the brand. Through an expanded sales force and
      related marketing activities, the Company intends to promote awareness of
      the key advantages of the Company's ROCHESTER MEDICAL brand products over
      competitive continence care products. The sales force will focus its
      efforts on the relatively small number of significant buying groups,
      dealers, distributors, institutions and home care providers that control a
      substantial portion of product purchases in the Company's target markets.
      In order to penetrate these purchasers, the Company's sales force focuses
      on differentiating the Company's products on the basis of quality,
      improved medical outcomes and cost effectiveness. The Company intends to
      emphasize the sale of the FEMSOFT insert and Antibacterial Foley catheter
      through the ROCHESTER MEDICAL brand. The Company will also continue to
      expand its network of international distributors of ROCHESTER MEDICAL
      brand products.
 
    - UTILIZE PROPRIETARY TECHNOLOGIES TO EXPAND PRODUCT OFFERINGS.  The Company
      will continue development of disposable, latex-free continence care
      products using its proprietary technologies. The Company will seek to
      apply its capabilities in molding, shaping, and forming liquid
      encapsulated devices under programmed controls to develop new devices that
      are softer and more comfortable for the patient. The Company also intends
      to pursue opportunities to develop other continence care products using
      its antimicrobial matrix and polymer and adhesives technologies. In the
      longer term, the Company intends to explore opportunities for the
      development of innovative medical devices for other markets, such as fecal
      incontinence, ostomy and gastro-intestinal tubes, which will benefit from
      the softer, more conformable devices that can be produced using the
      Company's liquid encapsulation technologies.
 
    - LEVERAGE STRENGTHS IN AUTOMATED MANUFACTURING TECHNOLOGY.  The Company
      seeks to use its proprietary manufacturing processes, materials expertise,
      custom designed equipment and technical know-how to simplify and automate
      traditional manufacturing techniques for continence care products. In
      order to manufacture high quality products at competitive costs, the
      Company concurrently designs and develops new products and the processes
      and equipment to manufacture them. The Company's manufacturing technology
      is well suited to high-unit volume production of disposable devices on a
      cost effective basis. The Company believes that controlling the cost of
      the device is an important factor in the market for disposable devices.
 
    - CAPITALIZE ON CONVATEC RELATIONSHIP AND OTHER PRIVATE LABEL
      ARRANGEMENTS.  The Company's growth strategy includes increasing its share
      of the continence care market through its relationship with ConvaTec and
      other private label arrangements. The Company will continue to work
      closely with ConvaTec to increase sales under their strategic alliance and
      to increase the Company's access to worldwide markets. In addition, the
      Company, subject to the rights of ConvaTec, will continue to distribute
      its products under private label arrangements with other established
      medical products companies.

  URINARY DYSFUNCTION
 
    FEMSOFT INSERT
 
    The FEMSOFT insert is a disposable device currently in clinical trials for
the management of stress incontinence in active women. It is a soft, conformable
urethral insert that assists the female urethra and bladder neck to control the
involuntary loss of urine. The device can be simply inserted, worn and removed
for voiding by most women. It requires no inflation, deflation, syringes or
valving mechanisms. For a depiction of the FEMSOFT insert, see the inside front
cover of this Prospectus.
 
    PRODUCT DESCRIPTION.  The FEMSOFT insert consists of a small cylindrical,
liquid-filled silicone membrane, approximately two inches in length. The
membrane has a bulb-shaped portion near the tip and an oval-shaped tab at the
end that remains outside the urethra. The tip of the device is inserted into the
urethra by use of a disposable applicator which resides in a central tube
extending the length of the device. As the device is inserted, the pressure from
the urethra compresses the bulb causing the liquid to move toward the external
end of the device. When the bulb portion enters the bladder, the pressure
exerted by the urethra causes the liquid to refill the bulb portion which seats
the device in the bladder neck and urethra. The user removes and discards the
disposable applicator, allowing the urethra to resume its natural curve and
shape. The silicone tab of the insert remains outside the urethra after
insertion. When a user needs to void, the tab is pulled to remove the insert;
the device is discarded and another inserted.
 
    The FEMSOFT insert is designed such that incidental pressures on the bladder
caused by normal activity, which are typically the immediate causes of stress
incontinence, improve the seal created by the device in the bladder neck,
thereby helping to prevent leakage. Steady pressure from a contracting bladder,
as during voluntary urination, will compress the bulb and expel the device,
thereby providing further ease of use and minimizing the possibility of harm in
persons who may be unable to otherwise remove the device due to injury or loss
of consciousness.
 
    TARGET MARKET.  The Company believes the FEMSOFT insert will provide
significant advantages in the management of female stress incontinence. The
FEMSOFT insert is a minimally invasive device that provides a patient with
effective control of her urinary function and eliminates the need for collection
bags and pads or liners that can cause embarrassment, restrict mobility and
compromise lifestyle. In addition, the soft, liquid-filled silicone membrane of
the FEMSOFT insert has been designed to conform to the irregular shape of the
urethra and follow the movements of the urethra during normal activities,
thereby helping to reduce chafing, abrasion and leakage. The FEMSOFT insert has
also been designed to provide a variable, supportive pressure to the muscles of
the urethra and bladder neck, while reducing tissue erosion and loss of muscle
tone. Although intended principally for the management of female stress
incontinence, the FEMSOFT insert may also be suitable for the management of some
conditions of urge incontinence or mixed stress and urge incontinence.
 
    The FEMSOFT insert will be a prescription device that will require the
patient to visit her physician. Before a patient begins using the FEMSOFT
insert, the physician will fit the patient with the proper size and instruct the
patient on proper application of the FEMSOFT insert. The Company anticipates
manufacturing the device in combinations of three widths to provide a proper
fit.
 
    CLINICAL TRIAL PROGRAM.  The FEMSOFT insert requires PMA approval by the FDA
before it may be marketed commercially. A clinical trial of the FEMSOFT insert
is being conducted at eight sites in the United States under an Investigational
Device Exemption ("IDE") application approved by the FDA. The clinical trial
protocol contemplates 120 patients studied over a 12 month period. Eighty-seven
patients are currently enrolled in the clinical trial. The Company submitted an
interim report to the FDA dated July 15, 1997. This report noted that 38
patients had used the FEMSOFT insert an aggregate of 2,101 times. In the trial,
each patient compared urine leakage and incontinence episodes during periods of
use of the device and periods of non-use.
 
                                       34
<PAGE>
    The Company believes the initial data contained in the interim report
demonstrates that use of the FEMSOFT insert results in a significant reduction
in the rate of incontinence episodes. The Company also believes that the FEMSOFT
insert has been well tolerated by the patients' urethral tissue and no negative
effects on that tissue were noted on follow-up pelvic or cystoscopic
examinations. In response to a written questionnaire, 94% of the patients have
reported a desire to continue use of the FEMSOFT insert. When asked whether they
had experienced urine leakage with the insert in place, 88.4% responded never or
rarely, 4% answered occasionally and 5.8% responded frequently. A total of 22
adverse events have been reported in the clinical trials, including 11 reported
infections and six instances of minor external tissue trauma associated with the
patients' inexperience in application of the FEMSOFT insert during the first
week of use. Five patients have withdrawn from the clinical trial, of whom one
withdrew due to recurrent infections. The Company believes the reported adverse
events represent the anticipated effects associated with the use of the FEMSOFT
insert. These results are preliminary and may not necessarily be indicative of
the final results of the clinical trial.
 
    The Company is continuing the multi-site FEMSOFT insert clinical trial to
collect the data necessary to submit a PMA regarding the FEMSOFT insert to the
FDA. The Company intends to submit a PMA based on the data to be derived from
the continuing clinical trial. The timing of this submission will depend on the
progress and results of the clinical trial and the Company's determination that
it has gathered sufficient data for a submission. The process for obtaining FDA
approval is unpredictable and often lengthy and there can be no assurance that
the FDA will grant approval in a timely manner, if at all. Even if regulatory
approval is obtained, there can be no assurance that the FEMSOFT insert will
perform as designed or will be successfully marketed. See "Risk Factors--Product
Development Risks; Lack of Regulatory Approval" and "--Government Regulation."
 
    MALE EXTERNAL CATHETERS
 
    The Company manufactures and markets three types of silicone male external
catheters: the ULTRAFLEX, POP-ON and WIDE BAND catheters. The ULTRAFLEX catheter
has adhesive positioned midway down a standard length catheter sheath. The
POP-ON catheter has a sheath that is shorter than that of a standard male
external catheter and has adhesive applied to the full length of the sheath. It
is designed to accommodate patients who have retracted penises or other physical
impediments to using standard length male external catheters. In addition, the
Company believes the POP-ON catheter may be used as an alternative to standard
length catheters.
 
    The Company's WIDE BAND self-adhering male external catheter, which is of
standard length, has an adhesive band which extends over the full length of the
sheath, providing approximately 70% more adhesive coverage than other male
external catheters currently marketed. The recently introduced WIDE BAND
catheter is designed to reduce the adhesive failure and resulting leakage that
may occur with male external catheters due to normal activities, which is a
common complaint among users of male external catheters. In light of this
advantage, the Company intends to focus its male external catheter marketing
efforts on this product.
 
    All of the Company's male external catheters are produced in five sizes for
better patient fit. The Company believes that its silicone male external
catheters have advantages compared both to latex catheters and to other
non-latex catheters. Silicone is a non-toxic, biocompatible and hypoallergenic
material that eliminates the risks of latex-related skin irritation. Silicone
catheters are also odor free and have greater gas permeability than catheters
made from other materials, including latex. Gas permeability reduces skin
irritation and damage from catheter use and thereby increases patient comfort.
Unlike latex male external catheters, the Company's silicone catheters are
transparent, permitting visual skin inspection without removal of the catheters
and aiding proper placement of the catheters. The Company's catheters also have
a kink-proof funnel design to ensure uninterrupted urine flow. The self-adhering
technology of the Company's catheters eases application of the catheters and
provides a strong bond to the skin for greater patient confidence and prolonged
wear. Finally, unlike the processes used by manufacturers of
 
                                       35
<PAGE>
competitive catheters, the Company's proprietary manufacturing processes enable
it to manufacture its POP-ON catheter with sufficient adhesive strength in a
shorter sheath.
 
    The Company sells silicone male external catheters under the ROCHESTER
MEDICAL brand and to private label customers. The WIDE BAND male external
catheter is currently sold only under the ROCHESTER MEDICAL brand.
 
    The Company also manufactures and sells male external catheters made from a
proprietary non-latex, non-silicone material to certain private label customers.
These catheters use the same self-adhesive technology as the Company's silicone
male external catheters. Like the silicone male external catheters, the
non-silicone catheters eliminate the risk of latex reactions and latex-related
skin irritations. The non-silicone catheters also are odor free.
 
    PERSONAL CATHETER
 
    The Company's PERSONAL CATHETER is a disposable intermittent catheter
manufactured from two different silicones, with a stiff core catheter tube and a
softer outer cover. This construction provides sufficient stiffness for ease of
insertion, while the softer cover is designed to reduce tissue irritation during
insertion. Most competitive intermittent catheters are made from thermoplastics,
which become stiffer when cool and more flexible when warm and which also tend
to deform if bent for any length of time, as when carried in a purse or pocket.
The PERSONAL CATHETER is not sensitive to normal temperature variations and does
not deform if bent for storage. The Company produces the PERSONAL CATHETER in
three lengths and multiple diameters. The Company introduced the PERSONAL
CATHETER in May 1997 and markets it under the ROCHESTER MEDICAL brand.
 
  URINE DRAINAGE
 
    ANTIBACTERIAL FOLEY CATHETER
 
    The Company's Antibacterial Foley catheter is a silicone Foley catheter that
incorporates all of the advantages of the Company's other marketed Foley
catheters (as described below) and has been designed to reduce the incidence of
bacterial CUTI. The Antibacterial Foley catheter incorporates a broad-spectrum
antibacterial agent, nitrofurazone, into the silicone matrix of the outer and
inner surfaces of the catheter in a formulation that gives sustained release of
the medication into and throughout the urethra and bladder neck while the
patient is catheterized. For a depiction of the Antibacterial Foley catheter,
see the inside front cover of this Prospectus.
 
    Nitrofurazone, which has been used for over 40 years, is effective against
both gram-positive and gram-negative bacteria. Laboratory tests conducted by the
University of Minnesota and funded by the Company have shown the imbedded
nitrofurazone in the Antibacterial Foley catheter to inhibit the growth of most
bacteria known to cause bacterial CUTI, including some common
antibiotic-resistant bacterial strains.
 
   
    The Company funded a prospective, randomized, double-blinded clinical trial
of the Antibacterial Foley catheter at the University of Wisconsin which
evaluated 344 patients in acute care, intensive care and surgical settings. This
completed clinical trial demonstrated that use of the Antibacterial Foley
catheter yielded a three-fold reduction in the incidence of bacterial CUTI
compared to use of a silicone, non-medicated Foley catheter in patients who were
catheterized for one to seven days, a period that is typical of approximately
90% of all hospital Foley catheterizations. The Antibacterial Foley catheter was
well-tolerated by the patients using it, and no complications or attributable
side-effects or systemic absorption of nitrofurazone were observed. The clinical
study was designed and carried out by Dennis G. Maki, M.D., Professor of
Medicine and Head of the Section of Infectious Diseases in the Department of
Medicine of the University of Wisconsin Medical School, and Hospital
Epidemiologist.
    
 
                                       36
<PAGE>
    In May 1997, the Company submitted a 510(k) for the Antibacterial Foley
catheter based upon the University of Wisconsin clinical trial and the
University of Minnesota tests. Unless the Company obtains FDA clearance, the
product cannot be marketed in the United States. There can be no assurance that
the Company will obtain such FDA clearance in a timely manner or at all. Even if
regulatory clearance is obtained, there can be no assurance that the
Antibacterial Foley catheter will perform as designed or will be successfully
marketed. See "Risk Factors--Product Development Risks; Lack of Regulatory
Approval."
 
    The Company believes that the three-fold reduction in the incidence of
bacterial CUTI and the associated improved patient outcomes as indicated in the
Antibacterial Foley catheter clinical trials may provide potentially significant
cost savings to hospitals and other purchasers of urinary catheters and enable
the Company to position the Antibacterial Foley catheter as a premium product in
the market. The Company intends to sell the Antibacterial Foley catheter under
the ROCHESTER MEDICAL brand. The Company may also market the Antibacterial Foley
catheter through ConvaTec depending on the negotiation of mutually satisfactory
pricing terms. See "--Private Label Distribution Agreements."
 
    FOLEY CATHETERS
 
    The Company offers Foley catheters in a standard two lumen version and in a
three lumen version for irrigation of the urinary tract. These Foley catheters
are available in all standard adult and pediatric sizes as well as in
specialized pediatric sizes. All of the Company's silicone Foley catheters
eliminate the risk of the allergic reactions and tissue irritation and damage
that is sometimes associated with latex Foley catheters. The Company's Foley
catheters are transparent which enables healthcare professionals to observe
urine flow. The Company's standard Foley catheters also feature solid, rounded
tips for ease of insertion and smooth, proportional eyes for ease of insertion
and maximum drainage. Unlike the manufacturing processes used by producers of
competing silicone Foley catheters, in which the balloon portion is formed by
hand in a separate procedure involving gluing and burnishing, the Company's
automated manufacturing processes allow the Company to integrate the balloon
into the structure of the Foley catheter, resulting in a smoother, more uniform
exterior that may help reduce irritation to urinary tissue.
 
    The Company's standard Foley catheters are packaged in single catheter
strips and sold under the ROCHESTER MEDICAL brand and under private label
arrangements. In addition, the Company sells its standard Foley catheters in
bulk under private label arrangements for packaging in kits with tubing,
collection bags and other associated materials. The Company's standard silicone
Foley catheters are priced competitively compared to a substantial majority of
Foley catheters sold in the United States.
 
  OTHER ADVANCED DESIGN PRODUCTS
 
    COMFORT SLEEVE FOLEY CATHETER
 
    The COMFORT SLEEVE Foley catheter has a flexible, liquid-filled sheath
encasing the urethral section of the catheter tube, and is made from silicone
using the Company's liquid encapsulation technologies. The Company believes that
its COMFORT SLEEVE Foley catheter can provide improved patient comfort as
compared to other Foley catheters. Its liquid-filled urethral section is softer
and more pliable than other Foley catheters and its design permits the catheter
tube to move and rotate independently of the flexible encasing sheath, lessening
abrasion and irritation to the urethra during use. The Company believes these
features may be particularly beneficial to long-term catheterized patients,
including nursing home residents. The Company also believes that the COMFORT
SLEEVE Foley catheter can reduce the leakage sometimes associated with other
Foley catheters because the liquid-filled sheath of the COMFORT SLEEVE Foley
catheter conforms to the shape of the urethra.
 
    Although the Company has received 510(k) marketing clearance from the FDA to
market the COMFORT SLEEVE Foley catheter, the Company has not commenced
marketing. Prior to introducing the COMFORT SLEEVE Foley catheter, the Company
intends to conduct clinical preference testing with several leading physicians
 
                                       37
<PAGE>
and medical institutions in order to determine appropriate usage protocols and
patient preferences. The Company has not yet scheduled clinical preference
testing for the COMFORT SLEEVE Foley catheter.
 
    FEMALE CATHETER
 
    The female catheter is a disposable self-retaining urinary catheter designed
to continuously empty the bladder. The female catheter can be self-administered
to manage all forms of female incontinence. The female catheter can also be used
by medical professionals for urine drainage management during surgery and
post-operative recovery. The female catheter has been designed to be easy and
convenient for the patient to use. It consists of a silicone lumen surrounded by
a soft, liquid-filled silicone sleeve. To position the female catheter, the user
inserts a catheter through the urethra into the bladder. The user compresses a
self-contained liquid-filled reservoir to move the liquid through the catheter
sleeve to inflate an expandable portion of the catheter positioned inside the
bladder. A soft shroud covers the reservoir to prevent the liquid from flowing
back to the reservoir and to maintain inflation of the catheter. The female
catheter is then attached to any standard collection device. To deflate and
remove the female catheter, the shroud is easily pulled off the sleeve to allow
the liquid to flow back into the reservoir. The female catheter may be inserted
once daily, and the Company believes a majority of urinary incontinence
sufferers can safely position the catheter and inflate it after appropriate
training. Beyond its applications for urinary incontinence, the female catheter
may function as a more comfortable, less expensive replacement for some uses of
standard Foley catheters by women. The Company has received FDA 510(k) marketing
clearance for the female catheter but has not commenced marketing. Before
commercial introduction of this catheter, the Company intends to conduct
clinical preference tests with several leading physicians and medical
institutions to determine appropriate usage protocols and patient preferences.
The Company has not yet scheduled clinical testing of the female catheter. In
addition, while the Company currently can produce limited quantities of the
female catheter for testing and other purposes, the Company must complete the
installation and testing of its new automated production facility before
beginning production of commercial quantities of the female catheter.
 
    FEMALE VALVED CATHETER
 
   
    The Company is developing a female valved catheter that will use the same
construction and be administered in the same manner as the female catheter. The
female valved catheter is intended for use as a daily disposable device for
controlled periodic urine drainage throughout the day without removal. This
catheter would provide users with increased convenience because the device would
not require an exterior collection bag. The Company believes that the female
valved catheter may also be used throughout the day as an alternative in some
circumstances to intermittent catheterization. The female valved catheter
requires further research and development and will require significant clinical
testing before marketing clearance may be applied for and received from the FDA.
The Company has not yet scheduled such clinical testing for this catheter. There
can be no assurance that the female valved catheter may be successfully
developed or that clinical tests of the female valved catheter will support the
safety and efficacy of the catheter or that the FDA will approve the marketing
of the catheter in a timely manner, if at all. See "Risk Factors--Product
Development Risk; Lack of Regulatory Approval."
    
 
TECHNOLOGY
 
    The Company uses proprietary, automated manufacturing technologies and
processes to manufacture continence care devices cost effectively. The
production of the Company's products also depends on its materials expertise and
know-how in the formulation of silicone and advanced polymer products. The
Company's proprietary liquid encapsulation technology enables it to manufacture
innovative products, such as its FEMSOFT insert and COMFORT SLEEVE Foley and
female catheters, that have soft, conformable, liquid-filled reservoirs, which
cannot be manufactured using conventional technologies. Using this liquid
encapsulation technology, the Company can mold and form liquid encapsulated
devices in a variety of
 
                                       38
<PAGE>
shapes and sizes in an automated process. The Company's manufacturing
technologies and materials know-how also allow the Company to incorporate a
sustained release antibacterial agent into its products. The Company believes
that its manufacturing technology is particularly well-suited to high unit
volume production and that its automated processes enable cost-effective
production. The Company further believes that its manufacturing and materials
expertise, particularly its proprietary liquid encapsulation technology is
applicable to a variety of medical applications. The Company plans to consider,
commensurate with its resources, future research and development activities to
investigate opportunities provided by the Company's technology and know-how.
 
    The Company believes that its proprietary manufacturing processes, materials
expertise, custom designed equipment and technical know-how allow it to simplify
and further automate traditional catheter manufacturing techniques to reduce the
Company's manufacturing costs. In order to manufacture high quality products at
competitive costs, the Company concurrently designs and develops new products
and the processes and equipment to manufacture them.
 
MARKETING AND SALES
 
    To date, the majority of the Company's revenues have been derived from sales
of its products under private label arrangements with medical products
companies, and such arrangements, especially the arrangement with ConvaTec, are
likely to account for a significant portion of the Company's revenues in the
foreseeable future. However, the Company has begun to focus its marketing
efforts on gaining increased market recognition and sales of ROCHESTER MEDICAL
brand products. In particular, assuming it receives FDA approval, the Company
intends to focus on marketing and selling its Antibacterial Foley catheter and
the FEMSOFT insert under the ROCHESTER MEDICAL brand.
 
    SALES AND MARKETING OF ROCHESTER MEDICAL BRAND PRODUCTS.  The Company
directly sells ROCHESTER MEDICAL brand products in the domestic market,
primarily to key accounts consisting of significant buying groups, dealers,
distributors, institutions and home care providers. The Company believes that
purchasing power in the healthcare market is being centralized in these large
purchasers of healthcare products, and that there is an opportunity to market
effectively to a large portion of the domestic continence care market with a
limited, focused sales organization by marketing to these significant
purchasers. The Company's sales force focuses on differentiating the Company's
products on the basis of quality, the potential for improved medical outcomes
and cost effectiveness.
 
    The Company's North American sales organization currently consists of a
director of sales, six regional managers and one sales representative. The
Company is in the process of recruiting sales representatives for each of the
regions. This direct domestic sales force is supported by a small, centralized
customer service and telesales staff. For international sales of ROCHESTER
MEDICAL brand products, the Company has developed and continues to build a
network of independent distributors. The Company currently has arrangements
covering 38 countries.
 
   
    The Company believes that the introduction and marketing of the FEMSOFT
insert, if FDA marketing approval is received, will differ significantly from
that of its other products. The Company currently anticipates that this strategy
will require significant physician and clinician education efforts and
substantial consumer oriented media advertising. The educational efforts
directed to clinicians may include personal visits and demonstrations; the
preparation and presentation of instructions for the prescription, sizing and
use of the FEMSOFT insert and for follow-on procedures for patient care and
monitoring; and the preparation of written, audio and video materials for
clinicians to use for patient education purposes.
    
 
    CONVATEC AND OTHER PRIVATE LABEL ARRANGEMENTS.  The Company sells certain of
its current products, including male external and Foley catheters, under private
label arrangements to established medical products companies that provide the
Company with commercial distribution of its products, a large sales force and
broad access to the hospital, long-term care, home care and physician markets.
Under a
 
                                       39
<PAGE>
distribution and co-development agreement (the "ConvaTec Agreement"), and under
a separate agreement predating the ConvaTec Agreement, the Company supplies male
external and Foley catheters to ConvaTec, a division of a subsidiary of
Bristol-Myers Squibb Company. ConvaTec is a leading global manufacturer and
marketer of ostomy and modern wound care products and a comprehensive provider
of skin care, infection control, contamination control and incontinence care
products. ConvaTec has an extensive sales organization in the United States and
approximately 70 other countries. ConvaTec resells the Company's products under
its own brands. The Company is the exclusive supplier of Hollister's
requirements of self-adhering non-latex male external catheters which Hollister
resells under its own brand. The Company currently supplies Allegiance
Euromedical with silicone Foley catheters. The Company supplies Mentor with
silicone male external catheters, which Mentor resells under its own brand. See
"--Private Label Distribution Agreements."
 
MANUFACTURING
 
    The Company designs and builds custom equipment to implement its
manufacturing technologies and processes. The Company's manufacturing facilities
are located in Stewartville, Minnesota. The Company produces its Foley catheters
on one production line and its male external catheters on a second line. The
Company has expanded its current manufacturing facility and is currently
completing the installation of additional manufacturing equipment for its male
external and Foley catheter products. The Company has also constructed a new
manufacturing facility to house its liquid encapsulation manufacturing
operations. The Company is currently in the process of installing the
manufacturing line for this facility.
 
    The Company maintains a comprehensive quality assurance and quality control
program, which includes documentation of all material specifications, operating
procedures, equipment maintenance and quality control test methods. To control
the quality of its finished product, the Company uses ongoing statistical
process control systems during the manufacturing process and comprehensive
performance testing of finished goods. Each Foley catheter's balloon function is
tested, and each male external catheter is visually inspected. The Company has
recently obtained ISO 9001 certification and quality system certification for
the CE mark for its Foley catheter and male external catheter production lines.
The Company will be required to obtain additional ISO 9001 and CE mark
certifications for the new liquid encapsulation manufacturing line through a
separate qualification process.
 
    The Company's manufacturing facility has been designed to accommodate the
specialized requirements for the manufacture of medical devices, including the
FDA's regulations concerning Quality System Regulation for current good
manufacturing practices ("GMP").
 
    In connection with the PMA for the FEMSOFT insert, the Company will be
required to establish that its new liquid encapsulation manufacturing facility
complies with GMP. In 1995, the FDA conducted a routine inspection of the
Company's existing manufacturing facility, in which the Company's facility,
documentation and quality control systems were evaluated and no substantial
matters of non-compliance with GMP were raised with the Company. In 1996, the
Minnesota Pollution Control Agency awarded the Company public recognition for
its environmental compliance program and procedures. See "--Government
Regulation."
 
SOURCES OF SUPPLY
 
    The Company obtains certain raw materials and components for a number of its
products from single suppliers. The Company depends on Dow Corning and GE for
raw materials used in the manufacture of its silicone male external Foley and
intermittent catheters. The loss of either of these suppliers, or a material
interruption of deliveries from either one, could have a material adverse effect
on the Company. Although the Company considers its relationship with Dow Corning
to be satisfactory, Dow Corning is currently in bankruptcy proceedings and there
can be no assurance that Dow Corning will continue to manufacture silicone or to
supply silicone to medical device manufacturers, such as the Company. The
Company
 
                                       40
<PAGE>
believes that most, if not all, of the silicone it currently purchases from Dow
Corning or GE could be replaced by silicone from other suppliers, and the
Company has located and evaluated other potential suppliers. In the event that
the Company had to replace Dow Corning or GE, however, the Company would be
required to repeat biocompatibility testing of its products using the silicone
from the new supplier, which may result in disruption of the Company's
production of catheters, and might be required to obtain additional regulatory
clearances.
 
    The Company is dependent on Shell for raw materials for the polymer used in
manufacturing the Company's non-silicone male external catheters. During 1994, a
disruption in Shell's production of these materials caused the Company to
curtail production of these catheters during the fourth quarter of fiscal 1994.
Although the Company adjusted to the disruption by reformulating this product,
the future loss of raw materials from this supplier could have a material
adverse effect on the Company. In the event that the Company had to replace
Shell, however, the Company would be required to repeat biocompatibility testing
of its products using the materials from the new supplier, which may result in
disruption of the Company's production of non-silicone male external catheters,
and might be required to obtain additional regulatory clearances.
 
    To date, the Company fulfills its requirements for nitrofurazone, which is
used in its Antibacterial Foley catheter, through a single distributor. Although
the Company is aware of other distributors who are able to supply nitrofurazone,
the Company does not currently have arrangements for alternative supplies. In
the event that the Company had to replace its supplier, the Company would be
required to repeat biocompatibility testing of its products using the materials
from the new supplier, which may disrupt the timing of the Company's
introduction of its Antibacterial Foley catheter, and might also require
additional regulatory clearances. There can be no assurance that alternative
sources will be available on reasonable terms, if at all.
 
    The Company believes there are adequate alternative sources of supply
available for the Company's other raw material requirements. In order to
minimize the possibilities of disruption in the production of its products, the
Company has begun to conduct routine sourcing and testing of raw materials,
including silicone and other polymers, in order to provide alternate sources of
raw materials in the event of supply shortages from its current suppliers. See
"Risk Factors--Dependence on Single or Limited Sources of Supply."
 
RESEARCH AND DEVELOPMENT
 
    The Company believes that its ability to add new products to its existing
continence care product line is important to the Company's future success.
Accordingly, the Company is engaged in ongoing research and development to
introduce new products which provide additional features and functionality.
 
    The Company's principal research and development efforts are currently
directed toward bringing the Antibacterial Foley catheter through the 510(k)
process, as well as on completing clinical trials of the FEMSOFT insert. The
Company is also focused on installing and testing standard and customized
components for its automated liquid encapsulation line in its new manufacturing
facility and on installing and testing equipment for the expansion of its
current male external and Foley catheter manufacturing operations. In the
future, the Company also intends to perform clinical studies for its other
advanced design catheter products that have obtained FDA clearance and other
products in development.
 
COMPETITION
 
    The continence management market is highly competitive. The Company believes
that the primary competitive factors include price, product quality, technical
capability, breadth of product line and distribution capabilities. The Company's
ability to compete is affected by its product development and innovation
capabilities, its ability to obtain regulatory clearances, its ability to
protect the proprietary technology of its products and manufacturing processes,
its marketing capabilities, its ability to attract and retain skilled employees,
and, for products sold in managed care environments, its ability to maintain
 
                                       41
<PAGE>
current distribution relationships and establish new distribution relationships.
The Company believes that it will be important for the Company to differentiate
its products in order to attract large customers, such as healthcare buying
groups, distributors, dealers, institutions and home care organizations.
 
    The Company's products compete with a number of alternative products and
treatments for continence management. The Company's ability to compete with
these alternative methods for urinary continence management depends on the
relative market acceptance of alternative products and therapies and the
technological advances in these alternative products and therapies. Any
development of a broad-based and effective cure for a significant form of
incontinence could have a material adverse effect on sales of incontinence
management devices such as the Company's products.
 
    The Company competes directly for sales of continence management devices
under the Company's own brand with larger, multi-product medical device
manufacturers and distributors such as ConvaTec, C.R. Bard, Inc., Allegiance
Euromedical, Kendall Healthcare Products Company, Sherwood Medical Company,
Hollister and Mentor. In order to compete in the developing managed care
environment in the United States, the Company also supplies various male
external and Foley catheters to certain of these competitors (ConvaTec,
Allegiance, Mentor and Hollister) who market such devices under their own brands
as a part of their broader product lines. UroMed recently introduced female
incontinence devices for the daily management of female incontinence that will
likely compete with the FEMSOFT insert and certain other of the Company's
products. Many of the competitive alternative products to the Company's
catheters are distributed by larger competitors including Johnson & Johnson
Personal Products Company, Kimberly-Clark Corporation and Proctor & Gamble
Company (for adult diapers and absorbent pads), and C.R. Bard, Inc. (for
injectable materials). Many of the Company's competitors, potential competitors
and providers of alternative therapies have significantly greater financial,
manufacturing, marketing, distribution and technical resources and experience
than the Company. It is possible that other large healthcare and consumer
products companies may enter this market in the future. Furthermore, academic
institutions, governmental agencies and other public and private research
organizations will continue to conduct research, seek patent protection and
establish arrangements for commercializing products in this market. Such
products may compete directly with any products which may be offered by the
Company.
 
PATENTS AND PROPRIETARY RIGHTS
 
   
    The Company's success may depend in part on its ability to obtain patent
protection for its products and manufacturing processes, to preserve its trade
secrets and to operate without infringing the proprietary rights of third
parties. The Company may seek patents on certain features of its products and
technology based on the Company's analysis of various business considerations,
such as the cost of obtaining a patent, the likely scope of patent protection
and the benefits of patent protection relative to relying on trade secret
protection. The Company also relies upon trade secrets, know-how and continuing
technological innovations to develop and maintain its competitive position.
    
 
    The Company owns 14 United States patents and a number of foreign patents
that generally relate to certain of the Company's catheters and devices and
certain of the Company's production processes. In addition, the Company owns a
number of pending United States and foreign patent applications. The Company may
file additional patent applications for certain of the Company's current and
proposed products and processes in the future.
 
    There can be no assurance that the Company's patents will be of sufficient
scope or strength to provide meaningful protection of the Company's products and
technologies. The coverage sought in a patent application can be denied or
significantly reduced before the patent is issued. In addition, there can be no
assurance that the Company's patents will not be challenged, invalidated or
circumvented or that the rights granted thereunder will provide proprietary
protection or commercial advantage to the Company.
 
                                       42
<PAGE>
Should attempts be made to challenge, invalidate or circumvent the Company's
patents in the United States Patent and Trademark Office and/or courts of
competent jurisdiction, including administrative boards or tribunals, the
Company may have to participate in legal or quasi-legal proceedings therein, to
maintain, defend or enforce its rights in these patents. Any legal proceedings
to maintain, defend or enforce the Company's patent rights can be lengthy and
costly, with no guarantee of success. There also can be no assurance that the
Company will file additional patent applications or that additional patents will
issue from the Company's pending patent applications.
 
   
    A claim by third parties that the Company's current products or products
under development allegedly infringe their patent rights could have a material
adverse effect on the Company. The Company is aware that others, including
UroMed, a manufacturer of a urethral insert, have obtained or are pursuing
patent protection for various aspects of the design, production and
manufacturing of continence care products. The medical device industry is
characterized by frequent and substantial intellectual property litigation,
particularly with respect to newly developed technology. The Company has
received an opinion from patent counsel to the effect that the FEMSOFT insert as
configured, as of the date of the opinion, does not infringe a United States
patent held by UroMed. The opinion only represents the reasoned professional
judgment of the Company's patent counsel and is not binding on any court or
third party. This opinion of patent counsel would not preclude an action for
patent infringement by UroMed, and UroMed could choose to bring an action
alleging infringement of the UroMed patent at any time in the future.
Intellectual property litigation is complex and expensive, and the outcome of
such litigation is difficult to predict. Any future litigation, regardless of
outcome, could result in substantial expense to the Company and significant
diversion of the efforts of the Company's technical and management personnel. An
adverse determination in any such proceeding could subject the Company to
significant liabilities to third parties, require disputed rights to be licensed
from such parties, if licenses to such rights could be obtained, and/or require
the Company to cease using such technology. There can be no assurance that if
such licenses were obtainable, they would be obtainable at costs reasonable to
the Company. If forced to cease using such technology, there can be no assurance
that the Company would be able to develop or obtain alternate technology.
Additionally, if third party patents containing claims affecting the Company's
technology are issued and such claims are determined to be valid, there can be
no assurance that the Company would be able to obtain licenses to such patents
at costs reasonable to the Company, if at all, or be able to develop or obtain
alternate technology. Accordingly, an adverse determination in a judicial or
administrative proceeding or failure to obtain necessary licenses could prevent
the Company from manufacturing, using or selling certain of its products, which
could have a material adverse effect on the Company's business, financial
condition and results of operations.
    
 
    There also can be no assurance that any third party does not currently have,
has not applied for, or might not in the future apply for, additional patents in
the United States which, if ultimately granted, might be infringed by any of the
Company's products as currently configured or any other product of the Company
and provide the basis for an infringement action against the Company.
 
    The Company also relies on proprietary manufacturing processes and
techniques, materials expertise and trade secrets applicable to the manufacture
of its products. The Company seeks to maintain the confidentiality of this
proprietary information. There can be no assurance, however, that these measures
will provide the Company with adequate protection of its proprietary information
or with adequate remedies in the event of unauthorized use or disclosure. In
addition, there can be no assurance that the Company's competitors will not
independently develop or otherwise gain access to processes, techniques or trade
secrets that are similar or superior to the Company's. Finally, as with patent
rights, legal action to enforce trade secret rights can be lengthy and costly,
with no guarantee of success. See "Risk Factors-- Dependence on Patents and
Proprietary Rights."
 
                                       43
<PAGE>
GOVERNMENT REGULATION
 
    The manufacture and sale of the Company's products are subject to regulation
by numerous governmental authorities, principally the FDA and corresponding
foreign agencies. In the United States, the medical devices manufactured and
sold by the Company are subject to laws and regulations administered by the FDA,
including regulations concerning the prerequisites to commercial marketing, the
conduct of clinical investigations, compliance with GMP and labeling.
 
    A manufacturer may seek from the FDA market authorization to distribute a
new medical device by filing a 510(k) to establish that the device is
"substantially equivalent" to medical devices legally marketed in the United
States prior to the Medical Device Amendments of 1976. A manufacturer may also
seek market authorization for a new medical device through the more rigorous PMA
process, which requires the FDA to determine that the device is safe and
effective for the purposes intended.
 
   
    All of the Company's currently marketed products have received FDA marketing
authorization pursuant to 510(k)s filed by the Company. The Company has
submitted a 510(k) for the Antibacterial Foley catheter based upon the clinical
data derived from the University of Wisconsin clinical trial and the University
of Minnesota study. Following this submission, the Company has received and
responded to an FDA letter requesting additional information and providing
comments on the Company's submission. The Company is currently waiting for an
action by the FDA. The FDA may require further information, such as additional
test data, before making a determination regarding substantial equivalence. The
FDA may also determine that the proposed device is not substantially equivalent
and require the Company to file a PMA application for this device. There can be
no assurance that the Company will receive FDA authorization to market the
Antibacterial Foley catheter or that market introduction of the Antibacterial
Foley catheter will not be delayed.
    
 
    The Company has yet to apply for and receive FDA marketing authorization for
certain of its devices. The Company has received approval of an IDE application
to conduct multi-site clinical studies of its FEMSOFT insert, which commenced in
early 1997. Upon receipt of the clinical data to be derived from that study, the
Company plans to submit the FEMSOFT insert for FDA marketing authorization
through the PMA application process. A PMA application must be supported by
extensive data, including preclinical and clinical trial data, as well as
extensive literature to prove the safety and effectiveness of the device.
Following receipt of a PMA application, if the FDA determines that the
application is sufficiently complete to permit a substantive review the FDA will
"file" the application. The FDA has 180 days to review a PMA application,
although the review of such an application more often occurs over a protracted
time period, and generally takes approximately two years or more from the date
of filing to complete.
 
    The PMA application approval process can be expensive, uncertain and
lengthy. A number of devices for which pre-market approval has been sought have
never been approved for marketing. The review time is often significantly
extended by the FDA, which may require more information or clarification of
information already provided in the filing. During the review period, an
advisory committee likely will be convened to review and evaluate the
application and provide recommendations to the FDA as to whether the device
should be approved. In addition, the FDA will inspect the manufacturing facility
to ensure compliance with the FDA's GMP requirements prior to approval of an
application. If granted, the approval of the PMA application may include
significant limitations on the indicated uses for which a product may be
marketed.
 
    The Company intends to pursue the PMA process for the female valved
catheter, personnel and budgetary constraints permitting. Other products that
the Company may consider for development, if and when developed, will require
marketing authorization by the FDA.
 
    The Company is also required to register with the FDA as a medical device
manufacturer. As such, the Company's manufacturing facilities are inspected on a
routine basis for compliance with GMP. These regulations require that the
Company manufacture its products and maintain its documents in a prescribed
 
                                       44
<PAGE>
manner with respect to manufacturing, testing and quality control activities.
The Company underwent its latest GMP inspection by the FDA in July 1995, and no
substantial matters of non-compliance were reported to the Company. In
connection with the PMA for the FEMSOFT insert, if any, the Company will be
required to establish that its new liquid encapsulation manufacturing facility
complies with GMP. As a medical device manufacturer, the Company is further
required to comply with FDA requirements regarding the reporting of adverse
events associated with the use of its medical devices, as well as product
malfunctions that would likely cause or contribute to death or serious injury if
the malfunction were to recur. FDA regulations also govern product labeling and
prohibit a manufacturer from marketing an approved device for unapproved
applications. If the FDA believes that a manufacturer is not in compliance with
the law, it can institute enforcement proceedings to detain or seize products,
issue a recall, enjoin future violations and assess civil and criminal penalties
against the manufacturer, its officers and employees.
 
    The Company may become subject to future legislation and regulations
concerning the manufacture and marketing of medical devices. Such future
legislation and regulations could increase the cost and time necessary to begin
marketing new products and could affect the Company in other respects not
currently foreseeable. The Company cannot predict the effect of possible future
legislation and regulations.
 
    Sales of medical devices outside the United States are subject to foreign
regulatory requirements that vary widely from country to country. These laws and
regulations range from simple product registration requirements in some
countries to complex clearance and production controls in others. As a result,
the processes and time periods required to obtain foreign marketing approval may
be longer or shorter than those necessary to obtain FDA approval. These
differences may affect the efficiency and timeliness of international market
introduction of the Company's products. For countries in the European Union
("EU"), in January 1995, CE Mark certification procedures became available for
medical devices, the successful completion of which would allow certified
devices to be placed on the market in all EU countries. After June 1998, medical
devices may not be sold in EU countries unless they display the CE Mark. In
order to obtain and maintain the CE mark, the Company must comply with the EU
Medical Device Directive ("KU Directive") and pass an initial and annual
facilities audit inspections by an EU inspection agency. The EU Directive
requires compliance with ISO 9001 and other specified standards. The Company has
recently obtained ISO 9001 certification and quality system certification for
the CE mark for its currently marketed products. In order to maintain
certification, if granted, the Company will be required to pass annual
facilities audit inspections conducted by EU inspectors. The certification is
site specific, and the Company will undergo a similar certification process for
its new FEMSOFT manufacturing facility. There can be no assurance, however, that
the Company will be able to maintain regulatory approvals or clearances,
including CE mark certification, for its products in foreign countries.
 
    In addition, international sales of medical devices manufactured in the
United States that have not been approved by the FDA for marketing in the United
States are subject to FDA export requirements. These require that the Company
obtain documentation from the medical device regulatory authority of the
destination country stating that sale of the medical device is not in violation
of that country's medical device laws, and, under some circumstances, may
require the Company to apply to the FDA for permission to export a device to
that country.
 
    Under certain of the Company's international distribution agreements, the
other parties have agreed to bear the burdens and costs of obtaining applicable
export and international regulatory approvals. The Company has agreed to
cooperate where necessary in obtaining such approval.
 
THIRD PARTY REIMBURSEMENT
 
    In the United States, healthcare providers that purchase medical devices
generally rely on third party payors, such as Medicare, Medicaid, private health
insurance plans and managed care organizations, to reimburse all or a portion of
the cost of the devices. The Medicare program is funded and administered by
 
                                       45
<PAGE>
the federal government, while the Medicaid program is jointly funded by the
federal government and the states, which administer the program under general
federal oversight. The Company believes its currently marketed products are
generally eligible for coverage under these third party reimbursement programs,
and that its Antibacterial Foley catheter, will also be eligible for third party
reimbursement. The Company is currently unable to assess eligibility of the
FEMSOFT insert for reimbursement. As a result, the competitive position of
certain of the Company's products may be partially dependent upon the extent of
reimbursement for its products. See "Risk Factors--Dependence on Third Party
Reimbursement."
 
    The federal government and certain state governments are currently
considering a number of proposals to reform the Medicare and Medicaid health
care reimbursement system. The Company is unable to evaluate what legislation
may be drafted and whether or when any such legislation will be enacted and
implemented. Certain of the proposals, if adopted, could have an adverse effect
on the Company's business, financial condition and results of operations.
 
PRIVATE LABEL DISTRIBUTION AGREEMENTS
 
    CONVATEC.  On August 11, 1995, the Company entered into the ConvaTec
Agreement, which grants ConvaTec, subject to obligations and limitations imposed
by certain of the Company's other distribution agreements, worldwide rights to
market the Company's products that, as of the date of the Agreement, were
currently produced or in development ("Products in Development") under
ConvaTec's brand. At the same time, the Company retains worldwide rights to
market its products under the ROCHESTER MEDICAL brand.
 
    The ConvaTec Agreement provides that ConvaTec will purchase all of its
requirements of certain of the Company's products from the Company. However, the
Convatec Agreement does not include any minimum purchase requirements or require
that ConvaTec market any or all of the Company's products. The Company will
provide all manufacturing and packaging of the Company's products for ConvaTec.
The Convatec Agreement provides, however, in the event that the Company is
unable to supply ConvaTec's requirements for products for any reason other than
a shortage of raw materials and the Company is unable to find a suitable
replacement in a commercially reasonable time, ConvaTec will be deemed to have a
license to the Company's technologies for purposes of manufacturing products for
ConvaTec. The Company currently supplies ConvaTec with silicone male external
catheters and Foley catheters. As the Company's Products in Development become
available for commercial sale in the future, the ConvaTec Agreement calls for
the Company and ConvaTec to negotiate in good-faith on packaging, quality
control specifications and pricing for each of those products. To maintain its
marketing rights to those Products in Development, ConvaTec is obligated to make
good faith efforts to market such additional products within 18 months following
the Company's first commercial sale of any such products. In addition, the
Company and ConvaTec may agree to work cooperatively to develop additional
incontinence and urology products. The Company is obligated to offer ConvaTec a
right of first refusal to market all products developed after the date of the
ConvaTec Agreement ("Future Products"). In addition, prior to entering into a
distribution agreement for any Future Product with a third party, the Company
must offer ConvaTec a final opportunity to market such product on terms no less
favorable to ConvaTec than those offered to the third party.
 
    The Company and ConvaTec are currently in discussions regarding the status
of the FEMSOFT insert under the ConvaTec Agreement. The Company's position is
that the FEMSOFT insert is a Future Product that is subject only to ConvaTec's
rights of first refusal and last offer. ConvaTec has expressed its view that the
FEMSOFT insert is a Product in Development and therefore subject to ConvaTec's
exclusive rights to be the private label distributor of the FEMSOFT insert. If
the Company and ConvaTec are unable to reach agreement, these issues will be
resolved by arbitration under the terms of the ConvaTec Agreement.
 
    The ConvaTec Agreement has an initial term expiring August 31, 2000.
ConvaTec may, at its option, renew the ConvaTec Agreement for an additional
five-year term, and may thereafter renew the ConvaTec
 
                                       46
<PAGE>
Agreement for up to five additional one-year renewal periods through August 31,
2010. Either party may terminate the ConvaTec Agreement only upon the other
party's material breach of the ConvaTec Agreement, bankruptcy or insolvency, or
inability to perform under the ConvaTec Agreement for a period of more than six
months. The ConvaTec Agreement may not be terminated in the event that a third
party acquires the Company. The Company has agreed to indemnify ConvaTec against
certain liabilities, including any patent infringement claims by third parties.
 
    Under a separate agreement, the Company supplies ConvaTec with tape-on
non-silicone male external catheters. This agreement has an initial term
expiring September 1999 and is subject to automatic annual renewals cancelable
on six months notice by either party. The agreement may be terminated at any
time, upon six months written notice given by ConvaTec without cause, or by the
Company if ConvaTec fails to make certain agreed minimum purchases.
 
    Sales of products to ConvaTec represented 12% of the Company's revenues in
fiscal 1996 and 28% of revenues for the nine months ended June 30, 1997.
 
    HOLLISTER.  The Company is the exclusive supplier of Hollister's
requirements of self-adhering non-latex male external catheters which Hollister
resells under its own brand. As a part of its agreement with Hollister, the
Company has agreed to restrict its ability to sell self-adhering non-silicone
male external catheters on a private label basis to other manufacturers and
distributors for distribution outside of the United States and Canada. The
parties recently agreed to a four-year extension of the original agreement
beginning May 1, 1998 and expiring April 30, 2002. During that period, Hollister
is subject to a minimum purchase requirement of four million non-silicone
catheters at the rate of at least one million catheters per year. Sales of
products to Hollister represented 12% of the Company's revenues in fiscal 1996
and 9% of revenues for the nine months ended June 30, 1997.
 
    ALLEGIANCE EUROMEDICAL.  Under a two-year agreement which expired on
November 30, 1996, the Company was the exclusive supplier to Allegiance
Euromedical of Allegiance Euromedical's requirements of silicone Foley
catheters, and Allegiance Euromedical was the exclusive distributor of the
Company's standard silicone Foley catheters in Japan, Canada, Western Europe and
the Balkans (subject to grandfather rights for the Company's pre-existing
foreign distributors). Allegiance Euromedical was also a non-exclusive
distributor of silicone Foley catheters for all other territories. Recently, the
parties amended and restated their original agreement to eliminate and phase out
Allegiance Euromedical's exclusive distribution rights and eliminate Allegiance
Euromedical 's minimum purchase obligations. Allegiance Euromedical is now a
worldwide distributor of the Company's silicone Foley catheters. The amended and
restated agreement expires November 30, 1999. Sales of products to Allegiance
Euromedical represented 19% of the Company's revenues in fiscal 1996 and 4% of
revenues for the nine months ended June 30, 1997.
 
    MENTOR.  The Company sells silicone male external catheters to Mentor
pursuant to a Male External Catheter License, Sales and Distribution Agreement,
as modified in September 1995 (the "MEC Agreement"). Additionally, the Company
granted to Mentor a non-exclusive, paid-up, royalty free license to make, use
and sell silicone male external catheters that the Company currently sells to
Mentor. The Company also granted Mentor a non-exclusive, paid-up, royalty free
license to use for any purpose all technical know-how and/or trade secrets
disclosed by the Company to Mentor pursuant to or in connection with the MEC
Agreement which relate to the manufacture of silicone male external catheters.
In connection with such licenses, upon Mentor's request, the Company is required
to assist, consult, and cooperate with Mentor in the assembly, design,
engineering, manufacturing, inspection, and servicing of the catheters and
components thereof, as well as assist in the selection of the necessary and
proper plant layout, machinery, tools, equipment, and production flow for the
economical manufacture of the catheters and their components by Mentor. Mentor
must reimburse the Company for any costs incurred in providing such cooperation
and assistance.
 
                                       47
<PAGE>
    The license to manufacture, use and sell silicone male external catheters
may be assigned only in connection with Mentor's sale or disposition of its
external catheter product line, or in connection with the merger, consolidation,
or similar corporate reorganization of Mentor or the sale of all or
substantially all of its assets. Mentor may sublicense the license to use
technical know-how and/or trade secrets only for purposes other than the
manufacture of the catheter to persons who agree to maintain the confidentiality
of the Company's know-how and trade secrets.
 
    Sales of products to Mentor represented 29% of the Company's revenues in
fiscal 1996 and 31% of revenues for the nine months ended June 30, 1997.

                          DESCRIPTION OF CAPITAL STOCK
 
    The Company's authorized stock consists of 20,000,000 shares of capital
stock without par value. As of September 25, 1997, there were 4,133,500 shares
of Common Stock outstanding, held of record by 114 shareholders. All shares of
capital stock issued by the Company shall be shares of Common Stock, unless the
Company's Board of Directors establishes one or more classes or series of
capital stock having other rights and preferences.
 
COMMON STOCK
 
    The holders of shares of Common Stock are entitled to one vote for each
share held of record on all matters on which shareholders are entitled or
permitted to vote. There is no cumulative voting for the election of directors.
Subject to preferences that may be applicable to any outstanding preferred
stock, holders of Common Stock are entitled to receive ratably such dividends as
may lawfully be declared by the Board of Directors out of funds legally
available therefor and to share pro rata in any other distribution to the
holders of Common Stock. See "Dividend Policy." Holders of Common Stock have no
preemptive or subscription rights. There are no conversion rights, redemption
rights, sinking fund provisions or fixed dividend rights with respect to the
Common Stock. All outstanding shares of Common Stock are fully paid and
nonassessable, and the shares of Common Stock to be issued upon completion of
the offering will be fully paid and nonassessable.
 
PREFERRED STOCK
 
    The Company's Board of Directors is authorized to establish by resolution
different classes or series of stock and to fix the rights, preferences and
privileges, including dividend rights, dividend rates, conversion rights, voting
rights, terms of redemption, redemption prices, liquidation preferences and the
number of shares constituting any class or series or the designation of such
class or series without any further vote or action by the shareholders. Although
there is no current intention to do so, the issuance of a class or series of
stock with certain special rights or privileges could have the effect of
delaying, deferring or preventing a change in control of the Company which may
adversely affect the voting and other rights of the holders of Common Stock. See
"Risk Factors--Possible Issuances of Preferred Stock; Anti-Takeover Effects of
Minnesota Law."
 
WARRANTS
 
    The Company has issued warrants to purchase a total of 75,000 shares of
Common Stock at an exercise price of $14.85 per share to Dain Bosworth
Incorporated and Robert W. Baird & Co. Incorporated. These warrants were granted
in connection with services provided for a securities offering in November 1995.
Such warrants are currently exercisable and expire on November 20, 2000.
 
    The holders of the warrants (the "Warrantholders") have registration rights
pursuant to an agreement with the Company. Under this agreements, if the Company
proposes to register any of its securities under the Securities Act, the
Warrantholders are entitled, subject to certain restrictions and exceptions, to
include such warrants or shares of Common Stock in such registration. The
Company is required to bear all registration and selling expenses (other than
underwriters' discounts and commissions and fees of special counsel to the
Warrantholders) in such offering. In addition, the Warrantholders are entitled,
on one occasion only, to demand that the Company prepare and file a registration
statement at the Company's expense and to require the Company to use its best
efforts to effect such registration, subject to certain conditions and
limitations. The Warrantholders have waived their registration rights in
connection with this offering.

STATE LAW PROVISIONS WITH POTENTIAL ANTI-TAKEOVER EFFECT
 
    Certain provisions of Minnesota law described below could have an
anti-takeover effect. These provisions are intended to provide management
flexibility, to enhance the likelihood of continuity and stability in the
composition of the Company's Board of Directors and in the policies formulated
by the Board and to discourage an unsolicited takeover of the Company, if the
Board determines that such a takeover is not in the best interests of the
Company and its shareholders. However, these provisions could have the effect of
discouraging certain attempts to acquire the Company, which could deprive the
Company's shareholders of opportunities to sell their shares of Common Stock at
prices higher than prevailing market prices.
 
    Section 302A.671 of the Minnesota Statutes applies, with certain exceptions,
to any acquisition of voting stock of the Company (from a person other than the
Company, and other than in connection with certain mergers and exchanges to
which the Company is a party) resulting in the beneficial ownership of 20% or
more of the voting stock then outstanding. Section 302A.671 requires approval of
any such acquisition by a majority vote of the shareholders of the Company prior
to its consummation. In general, shares acquired in the absence of such approval
are denied voting rights and are redeemable at their then-fair market value by
the Company within 30 days after the acquiring person has failed to give a
timely information statement to the Company or the date the shareholders voted
not to grant voting rights to the acquiring person's shares.
 
    Section 302A.673 of the Minnesota Statutes generally prohibits any business
combination by the Company, or any subsidiary of the Company, with any
shareholder that purchases 10% or more of the Company's voting shares (an
"interested shareholder") within four years following such interested
shareholder's share acquisition date, unless the business combination is
approved by a committee of all of the disinterested members of the Board of
Directors before the interested shareholder's share acquisition date.
 
INDEMNIFICATION OF CERTAIN PERSONS
 
    Minnesota law and the Company's Bylaws provide that the Company shall, under
certain circumstances and subject to certain limitations, indemnify any person
made or threatened to be made a party to a proceeding by reason of that person's
former or present official capacity with the Company against judgments,
penalties, fines, settlements and reasonable expenses. Any such person is also
entitled, subject to certain limitations, to payment or reimbursement of
reasonable expenses in advance of the final disposition of the proceeding.
 
TRANSFER AGENT AND REGISTRAR
 
    The Transfer Agent and Registrar for the Common Stock is Norwest Bank,
Minnesota, National Association.

<PAGE>
                              PLAN OF DISTRIBUTION
 
    The Common Stock is being offered for sale by the Company on a best efforts,
all or nothing basis, to selected institutional investors. Vector Securities
International, Inc., the Placement Agent, has been retained pursuant to a
placement agency agreement to act as the exclusive agent for the Company in
connection with the arrangement of offers and sales of the Common Stock on a
best efforts basis.
 
    The Placement Agent is not obligated to and does not intend to itself take
(or purchase) any of the shares of Common Stock. It is anticipated that the
Placement Agent will obtain indications of interest from potential investors for

                         REPORT OF INDEPENDENT AUDITORS
 
Shareholders
Rochester Medical Corporation
 
    We have audited the accompanying balance sheets of Rochester Medical
Corporation as of September 30, 1995 and 1996, and the related statements of
operations, shareholders' equity and cash flows for each of the three years in
the period ended September 30, 1996. 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 Rochester Medical
Corporation at September 30, 1995 and 1996, and the results of its operations
and its cash flows for each of the three years in the period ended September 30,
1996, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                               SEPTEMBER 30, 1996
 
1.  BUSINESS ACTIVITY
 
    Rochester Medical Corporation (the "Company") develops, manufactures and
markets innovative urinary continence care products for urinary dysfunction
management and urine drainage management. The Company currently manufactures and
markets a broad line of functionally and technologically enhanced latex-free
versions of standard continence care products, including male external
catheters, Foley catheters and intermittent catheters. The Company is also
developing innovative and technologically advanced products designed to provide
clinically and commercially attractive solutions to continence care needs.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with a remaining
maturity of three months or less when purchased to be cash equivalents.
 
MARKETABLE SECURITIES
 
    Marketable securities are classified as available for sale and consist of US
Treasury Bills and certificates of deposit. At September 30, 1995 and 1996 and
at June 30, 1997, the market value of marketable securities approximates cost.
 
MANUFACTURING AND SALES
 
    The Company manufactures and sells its products to a full range of companies
in the medical industry on a worldwide basis. There is a concentration of sales
to larger medical wholesalers and distributors. The Company performs periodic
credit evaluations of its customers' financial condition. The Company requires
irrevocable letters of credit on sales to certain foreign customers. Receivables
generally are due within 30 days. Credit losses relating to customers
consistently have been within management expectations.
 
INVENTORIES
 
    Inventories, consisting of material, labor and manufacturing overhead, are
stated at the lower of cost or market. Cost is determined by the first-in,
first-out (FIFO) method.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost less accumulated depreciation.
Depreciation is based on estimated useful lives of 4-35 years computed using the
straight-line method.
 
PATENTS
 
    Capitalized costs include costs incurred in connection with making patent
applications for the Company's products and are amortized on a straight-line
basis over eight years. The Company periodically reviews its patents for
impairment of value. Any adjustment from the analysis is charged to operations.

                               SEPTEMBER 30, 1996
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
RESEARCH AND DEVELOPMENT COSTS
 
    Research and development costs are charged to operations as incurred.
Research and development costs include clinical testing costs, certain salary
and related expenses, other labor costs, materials and an allocation of certain
overhead expenses.
 
INCOME TAXES
 
    Income taxes are accounted for under the liability method.
 
STOCK-BASED COMPENSATION
 
    The Company follows Accounting Principles Board Opinion No. 25, "ACCOUNTING
FOR STOCK ISSUED TO EMPLOYEES" ("APB 25"), and related interpretations in
accounting for its stock options. Under APB 25, when the exercise price of stock
options equals the market price of the underlying stock on the date of grant, no
compensation expense is recognized.
 
    The Company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standards No 123, ACCOUNTING FOR STOCK-BASED COMPENSATION.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
    The Company will record impairment losses on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount.
 
NET LOSS PER SHARE
 
    Net loss per share is computed using the weighted average number of common
shares outstanding during the period. Common equivalent shares from stock
options and convertible debt are excluded from the computation as their effect
is antidilutive. In February 1997, the Financial Accounting Standards Board
(FASB) issued FASB Statement No. 128, "Earnings Per Share". This Statement
replaces the presentation of primary earnings per share (EPS) with basic EPS and
also requires dual presentation of basic and diluted EPS for entities with
complex capital structures. This statement is effective for financial statements
for periods ending after December 15, 1997. For the nine-month period ended June
30, 1997, there is no difference between the basic loss share under Statement
No. 128 and net loss per share as reported.
 
INTERIM FINANCIAL INFORMATION
 
    The accompanying financial statements as of June 30, 1997 and for the nine
month periods ended June 30, 1996 and 1997 are unaudited, but, in the opinion of
management of the Company, reflect all adjustments (consisting of normal and
recurring accruals) necessary for a fair presentation. The results of

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
operations for the nine month period ended June 30, 1997 are not necessarily
indicative of the results that may be expected for the full year ending
September 30, 1997.
 
RECLASSIFICATIONS
 
    Certain reclassifications have been made to the 1995 financial statements to
conform to the 1996 presentation.
 
3.  ADVERTISING COSTS
 
    The Company incurred advertising expenses of $104,000 and $234,000 for the
years ended September 30, 1995 and 1996, respectively, and $227,000 and $167,000
for the nine month periods ended June 30, 1996 and 1997, respectively. All
advertising costs are charged to operations as incurred.

directors on the date of each of the Company's Annual Meetings.
 
    In September 1995, the Board of Directors approved the 1995 Non-Statutory
Stock Option Plan, which authorized the issuance of up to 50,000 shares of
Common Stock. In October 1995, Medical Advisory Board members were granted
options to purchase 12,000 shares of the Company's Common Stock at an exercise
price of $15.75 per share.

5.  SHAREHOLDERS' EQUITY (CONTINUED)
    The number of stock options exercisable at September 30, 1994, 1995 and 1996
was 3,000, 32,750 and 105,625 at a weighted average exercise price of $9.75,
$8.69 and $9.75 per share, respectively.
 
    The Company has elected to follow Accounting Principles Board Opinion No.
25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES ("APB 25") and related
interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided under FASB
Statement No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION ("Statement 123"),
requires use of option valuation models that were not developed for use in
valuing employee stock options. Under APB 25, when the exercise price of the
Company's employee stock options equals the market price of the underlying stock
on the date of grant, no compensation expense is recognized.
 
    Pro forma information regarding net loss and loss per share is required by
Statement 123, and has been determined as if the Company had accounted for its
employee stock options under the fair value method of Statement 123. The fair
value of these options was estimated at the date of grant using the
Black-Scholes option pricing model with the following weighted average
assumptions: risk-free interest rate of 5.51%; volatility factor of the expected
market price of the Company's common stock of .34 and a weighted average
expected life of the option of five years.
 
    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions. Because the Company's employee stock options have
characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of its employee
stock options.
 
    For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the option's vesting period. The Company's
pro forma information is as follows:

WARRANTS
 
    In connection with the March 1990 sale of Common Stock, the Company issued
five year warrants to an agent to purchase 24,000 shares of the Company's Common

    In connection with the November 1990 initial public offering, the Company
issued five year warrants to the underwriter to purchase 36,000 shares of Common

the underwriters for a nominal purchase price five year warrants to purchase
75,000 shares of Common Stock at $14.85 per share. The warrants can be exercised
any time through November 2000.

approximates the carrying value based on current market conditions.
 
8.  COMMITMENTS
 
MINNESOTA TECHNOLOGIES INCORPORATED
 
    On September 30, 1992, Minnesota Technologies Incorporated ("MTI"), a
Minnesota non-profit development organization, provided the Company a grant of
$100,000 for the purpose of developing the automated production of Foley
catheters. Under the terms of the MTI grant, the Company has agreed to repay MTI
the amount of the grant together with 8% simple interest at the rate of 2.5% of
gross sales of Foley catheters. The Company has further agreed to convey to MTI
all rights in any intellectual property, including the manufacturing equipment
and any patents issued with respect thereto, upon occurrence of any of the
following events:
 
    1.  The Company dissolves, becomes inoperative, or abandons the intellectual
       property relating to the automated production of Foley catheters: or
 
    2.  More than 25% of its manufacturing or production facilities relating to
       Foley catheters are located outside the State of Minnesota before August
       17, 1999.
 
    The grant was accounted for as a reduction in the cost of the equipment.
Royalties earned by MTI are charged to operations as royalty expense. Royalty
expense totaled $11,900 in 1994, $33,200 in 1995, $52,653 in 1996 and $38,119

Management believes the fees paid for the services rendered to the Company were
on terms at least as favorable to the Company as could have been obtained from
an unrelated party.
 
    The chairman and chief executive officer of Mentor Corporation is the
brother of the CEO and President, the Vice President of Operations, and a member
of the board of directors of the Company (see Note 11).
 
    The Company entered into an agreement with Halcon, Inc. to purchase office
furniture valued at $258,000. A payment of $86,000 was made in fiscal 1996 and
$143,000 was paid during the nine month period ended June 30, 1997. The chief
executive officer of Halcon, Inc. is a director of the Company and the brother
of the CEO and President and the Vice President of Operations of the Company.
Management believes that the terms of the agreement are at least as favorable to
the Company as could have been obtained from an unrelated party.
 
    As part of an employment agreement, the Company agreed to loan the Executive
Vice President of the Company $226,000 to assist in purchasing a residence. The
loan was repaid in fiscal 1996.
 
11.  MENTOR AGREEMENT AND RELATED LITIGATION
 
    In April 1991, the Company entered into an exclusive license, sales and
distribution agreement ("MEC Agreement") for external catheters with Mentor
Corporation (Mentor) for which the Company received a non-refundable license fee
of $500,000. The agreement granted Mentor sales exclusivity for silicone
external catheters in North and South America, Africa, Australia, and Western
Europe and a patent license permitting Mentor to manufacture the catheter
itself.
 
    On September 11, 1995, the Company and Mentor entered into a settlement
agreement to conclude all pending litigation among Mentor, the Company and
certain of the Company's officers. As part of the settlement agreement, the
Company waived certain monetary claims against Mentor, which resulted in a
write-off of approximately $115,000 of accounts receivable from Mentor in the
fourth quarter of fiscal

1995. The Company previously wrote off $100,000 of Mentor accounts receivable in
the third quarter of fiscal 1995. The settlement agreement also provided that
Mentor purchase all of the Company's inventory of silicone male external
catheters held for sale to Mentor at an agreed upon transfer price. This sale
resulted in approximately $160,000 of net sales to Mentor during the fourth
quarter of fiscal 1995. As part of the settlement agreement, Mentor's sales
exclusivity was terminated.
 
12.  CONVATEC AGREEMENT
 
    On August 11, 1995, the Company entered into a Distribution and
Co-Development Agreement (the "Distribution Agreement") with ConvaTec, a
division of E.R. Squibb & Sons, Inc., a wholly-owned subsidiary to Bristol-Myers
Squibb Company ("ConvaTec"), for the purpose of marketing and distributing the
Company's incontinence and urological devices. Under the Distribution Agreement,
the Company has granted ConvaTec, subject to obligations and limitations imposed
by the Company's other distribution agreements, worldwide rights to market the
Company's current products and products in development. The Company is obligated
to offer ConvaTec rights of first and last refusal to market all products
developed after the date of the Distribution Agreement. Under the Distribution
Agreement, the Company retains worldwide marketing rights to its products under
the Rochester Medical brand.
 
    The Distribution Agreement has a five year term expiring August 31, 2000.
ConvaTec may, at its option, renew the Distribution Agreement for an additional
five year term, and thereafter, renew the Distribution Agreement for up to five
additional one year renewal periods. A party may terminate the Distribution
Agreement only upon the other party's material breach of the Distribution
Agreement, bankruptcy or insolvency, or an inability to perform under the
Distribution Agreement for a period of more than six months. The Distribution
Agreement may not be terminated in the event that a third party acquires the
Company. The Company has agreed to indemnify ConvaTec against certain
liabilities, including any patent infringement claims by third parties.

The Company manufactures and markets three types of silicone self-adhering male
external catheters. The UltraFlex-Registered Trademark- catheter has adhesive
positioned midway down a standard length catheter sheath. The Pop-On-TM-
catheter has a sheath that is shorter than that of a standard male external
catheter and has adhesive applied to the full length of the sheath. The Wide
Band-TM- catheter has an adhesive band which extends over the full length of a
standard length catheter sheath, providing approximately 70% more adhesive
coverage than other male external catheters currently marketed.
 
The Company offers silicone Foley catheters in a standard two lumen version and
in a three lumen version for irrigation of the urinary tract. These Foley
catheters are available in all standard adult and pediatric sizes as well as in
specialized pediatric sizes. The Company's automated manufacturing processes
allow the Company to integrate the balloon into the structure of the Foley
catheter, resulting in a smoother, more uniform exterior that may help reduce
irritation to urinary tissue.
 
The Company's Personal Catheter-TM- is a disposable intermittent catheter
manufactured from two different silicones, with a stiff core catheter tube and a
softer outer cover. This construction provides sufficient stiffness for ease of
insertion, while the softer outer cover is designed to reduce tissue irritation
during insertion.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 302A.521 of the Minnesota Statutes provides that a corporation shall
indemnify any person made or threatened to be made a party to a proceeding by
reason of the former or present official capacity of such person against
judgments, penalties, fines (including, without limitation, excise taxes
assessed against such person with respect to any employee benefit plan),
settlements and reasonable expenses, including attorneys' fees and
disbursements, incurred by such person in connection with the proceeding, if,
with respect to the acts or omissions of such person complained of in the
proceeding, such person (1) has not been indemnified therefor by another
organization or employee benefit plan for the same judgments, penalties or
fines; (2) acted in good faith; (3) received no improper personal benefit and
Section 302A.255 (with respect to director conflicts of interest), if
applicable, has been satisfied; (4) in the case of a criminal proceeding, had no
reasonable cause to believe the conduct was unlawful; and (5) in the case of
acts or omissions in such person's official capacity for the corporation,
reasonably believed that the conduct was in the best interests of the
corporation, or in the case of acts or omissions in such person's official
capacity for other affiliated organizations, reasonably believed that the
conduct was not opposed to the best interests of the corporation. Section
302A.521 also requires payment by a corporation, upon written request, of
reasonable expenses in advance of final disposition of the proceeding in certain
instances. A decision as to required indemnification is made by a disinterested
majority of the Board of Directors present at a meeting at which a disinterested
quorum is present, or by a designated committee of the Board, by special legal
counsel, by the shareholders or by a court.
 
    Provisions regarding indemnification of officers and directors of the
Registrant to the extent permitted by Section 302A.521 are contained in the
Registrant's Restated Bylaws (Exhibit 4.2 hereto, which is incorporated herein
by reference).
 
    Under the Placement Agent Agreement (Exhibit 1.1 hereto, which is
incorporated herein by reference), the Placement Agent has agreed to indemnify,
under certain conditions, the Company, its directors, certain of its officers
and persons who control the Company within the meaning of the Securities Act of
1933, as amended, against certain liabilities.

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 further undertakes that:
 
        (1) For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
    or 497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and this offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.

Shareholders
Rochester Medical Corporation
 
    We have audited the accompanying balance sheets of Rochester Medical
Corporation as of September 30, 1995 and 1996, and the related statements of
operations, shareholders' equity and cash flows for each of the three years in
the period ended September 30, 1996 and have issued our report thereon dated
October 18, 1996. Our audits also included the financial statement schedule
listed in Item 18 of this Registration Statement. This schedule is the
responsibility of the Company's management. Our responsibility is to express an
opinion based on our audits.
 
    In our opinion, the financial statement schedule referred to above, when
considered in relation to the basic financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.
