                                     PART I

ITEM 1.  BUSINESS

THE COMPANY

General

         PolyMedica Corporation ("the Company") is a leading provider of
targeted medical products and services primarily focused in the diabetes
supplies and consumer healthcare markets. The Company holds a leading position
in several expanding markets. The Company's products and services are grouped
within the following businesses: Diabetes Supplies; Consumer Healthcare, which
includes OTC ("over-the-counter") Medical Devices and Urinary Discomfort
Products; and Professional Products, which include Prescription Urologicals.

         I. Diabetes Supplies

         The Company entered the Diabetes Supplies business with its August 1996
acquisition of Liberty Medical Supply, Inc. ("Liberty Medical"). Liberty Medical
has grown to be the leading direct mail distributor of diabetes testing supplies
for senior citizens covered by Medicare. Liberty Medical's patient-focused
services serve more than 80,000 active customers throughout the United States.

         Liberty Medical is headquartered in Palm City, Florida and was founded
in 1989. Liberty Medical is a participating Medicare provider which directly
bills and is paid by Medicare and/or the patient's medi-gap insurer, rather than
the patient. This procedure benefits the patient by assuring automatic and
timely delivery of supplies, while avoiding the need for the patient to prepare
paperwork and pay the cost of the supplies while awaiting subsequent
reimbursement.

         Liberty Medical pioneered the development of sophisticated media
advertising to reach an untapped portion of the Medicare-eligible diabetes
patient market. Approximately $13 million has been spent primarily to accumulate
over 80,000 active customers and on building the Liberty Medical trade name
through a wide variety of media, principally television, but also including
print, direct mail, and radio.

         Approximately 16 million people, or roughly 6% of the total United
States population, are afflicted with diabetes, with about half of them having
actually been diagnosed. Approximately 1.2 million of these patients fall within
Liberty Medical's target market of senior citizens using insulin and eligible
for Medicare. This patient population is growing rapidly, with more than 650,000
new cases diagnosed each year in the entire population. Diabetes is a chronic
disease in which the body's metabolism of glucose is ineffective due to
inadequate production of insulin. Frequent monitoring of blood glucose has been
documented as an important part of managing diabetes to help avoid serious
medical complications, such as coronary artery disease, glaucoma, and
circulatory problems which can lead to limb amputation. The cost to manage
diabetes is high; the average person with diabetes spends $1,200 per year on
supplies to test and control the disease.

         Medicare currently reimburses up to 80% of the cost of testing supplies
for eligible diabetics, but does not reimburse for insulin or syringes and does
not reimburse non-insulin using diabetics. The 1997 Balanced Budget Act expands
Medicare coverage to include diabetics who do not use insulin. As a result, on
July 1, 1998, the market for Liberty Medical's services will grow by
approximately 2 million patients. According to statistics from the American
Diabetes Association (ADA), this change to cover non-insulin using patients will
increase the number of Medicare-eligible seniors with diabetes to approximately
3.2 million.

         II. Consumer Healthcare

         The Consumer Healthcare Group operating out of the Company's
subsidiary, PolyMedica Healthcare, Inc. or "PMH", focuses on female urinary
discomfort products, digital thermometry, medication compliance products, and
home health aid products. PMH holds the number one private label market position
in digital thermometry and the number two overall market position. These
products are sold through an extensive network to major retailers, including
most of the largest drug store chains and mass merchandisers. Sales of the
Company's digital thermometry products continue to grow through customer
expansion and new product introduction. The Company's urinary Discomfort
Products for women include AZO STANDARD(R), which is currently the number one
selling product in a growing market segment; AZO CRANBERRY(R), a dietary
supplement which helps maintain a healthy urinary tract; and the new AZO TEST
STRIPS(TM), a home diagnostic test kit for urinary tract infections.

                                       2
<PAGE>   3



         III.  Professional Products

         PolyMedica's Professional Products Group operating out of the Company's
subsidiary, PolyMedica Pharmaceuticals (U.S.A.), Inc. or "PMP", represents one
of the broadest lines of prescription urology products available (excluding
anti-infectives), including urinary analgesics, antispasmodics, topical
anesthetics and suppositories. The Company's URISED(R), ANESTACON(R),
CYSTOSPAZ(R) and CYSTOSPAZ-M(R) analgesics and antispasmodics provide effective
symptomatic relief for urinary pain, burning and spasms. B&O(R) and
AQUACHLORAL(R) suppositories are used by patients unable to tolerate oral
dosages of systemic analgesics and sedatives.

Sale of Wound Care Business

         In July 1997, the Company sold certain assets of its U.S. and U.K.
wound care operations. Under the terms of the sale, the purchaser, Innovative
Technologies Group Plc ("IT"), paid the Company $9.00 million in cash and issued
to the Company an unsecured promissory note in the face amount of $4.00 million.
The Company could realize an additional $4.50 million if IT achieves certain
milestones, based on the performance of IT's stock and the performance of the
acquired business. The Company will recognize additional proceeds in excess of
the $9.00 million cash received only when and to the extent realized. The
Company's fiscal year ended March 31, 1998 statement of operations includes a
$4.13 million pretax gain on the sale of the wound care business.

Business Strategies

         The Company's overall strategy is to transition from a
technology-driven company to a market-driven company. The May 1996 spinoff of
CardioTech, the August 1996 acquisition and subsequent expansion of Liberty
Medical, and the July 1997 sale of the wound care business were key components
of this strategy. The Company's strategy includes:

         Expand leadership position in providing diabetes supplies to senior
citizens. Since the August 1996 acquisition of Liberty Medical, the Company
invested in an ongoing program of television advertising to reach a much larger
portion of the Medicare-eligible diabetes patient market. This campaign has
resulted in a significant increase in sales as Liberty Medical has increased its
active customers from 17,000 to more than 80,000. The Company continues to seek
opportunities to deliver new products to a broader customer base by leveraging
its efficient, mail-order distribution system and software for billing and
customer monitoring. To manage its growth effectively, Liberty Medical continues
to expand, upgrade and develop its operations and information systems to
continue its high level of customer service.

         The July 1, 1998 expansion of Medicare reimbursement includes, for the
first time, non-insulin using patients; these patients represent a major
opportunity for the Company to leverage its current leading position in
direct-mail distribution to insulin using seniors. In addition, the Company has
begun re-contacting its existing database of more than 40,000 non-insulin using
seniors with diabetes in order to generate more repeat business and has produced
and is market-testing new television advertising which is targeted to both
insulin and non-insulin using customers.

         The Company is also exploring other expansion opportunities such as the
trend in managed care towards outsourcing diabetes care services to other payors
and providers.

         Grow the consumer healthcare business. Fueled by the growth in demand
for the Company's urinary discomfort products, as well as by the strength of
sales of the Company's digital thermometers, the consumer healthcare group
achieved a record level of sales in fiscal 1998. Continued growth in the
consumer healthcare market is a strategic objective as the Company seeks to
leverage leading positions in its core markets of urinary discomfort, digital
thermometry and medication compliance products.

         Acquire complementary businesses. In order to take advantage of
economies of scale in production and marketing, the Company continues to
evaluate opportunities for the acquisition of businesses and products which
complement the Company's existing product lines. In selecting and evaluating
acquisition candidates, the Company examines the potential market opportunities
for products that can be distributed through the Company's existing marketing
infrastructure by utilizing its strengths in sales, marketing and distribution.

Existing Products

         Diabetes Supplies. Liberty Medical ships to more than 80,000 customers
in the U.S., making it the largest direct-mail provider of diabetes testing
products in the country to Medicare-eligible seniors. Liberty Medical sells more
than 200 name-brand products supplied by Lifescan, Boehringer Mannheim, Bayer,
and others. These products include glucose test strips and monitors, 

                                       3

<PAGE>   4
lancets, insulin, syringes, and other products. Sales of glucose test strips
represented 51.9% of the Company's consolidated revenues for the fiscal year
ended March 31, 1998.

         Consumer Healthcare Products. PMH focuses on female urinary tract
discomfort, digital thermometry, and medication compliance products.

         The Company's three principal non-prescription pharmaceutical products
are AZO STANDARD(R), which provides relief from urinary tract discomfort; AZO
CRANBERRY(R), a dietary supplement which helps maintain a healthy urinary tract;
and the new AZO TEST STRIP(TM), a home diagnostic test kit for urinary tract
infections. As of March 31, 1998, the AZO line of products held the dominant
share of the OTC female urinary tract discomfort market (over 46%), despite a
new competitive entry with a large promotional budget.

         The Company markets a line of thermometers which includes products with
traditional mercury and digital displays. Sales of the Company's glass and
digital thermometers, both branded and private label represented 14.9% and 12.2%
of the Company's consolidated revenues for the fiscal years ended March 31, 1996
and 1997, respectively. The Company has the number one private-label market
thermometer position and number two overall market position. The Company custom
manufactures and/or distributes its other consumer healthcare products under the
brand names of BASIS(R), MEDI-AID(R), PolyMedica and PeeDee Dose(TM).

         Items in the Company's consumer healthcare product line are either
manufactured by the Company or by others to the Company's specifications or are
purchased by the Company for resale. In addition, the Company provides private
label products for many national retailers. The Company's major customers in the
United States include most of the top pharmacy chains, major supermarkets and
mass merchandisers, including CVS, Eckerd, Rite-Aid and Walgreen Co. as well as
the four largest drug wholesalers. The Company's consumer products are sold in
retail pharmacies in the beauty aid, cough and cold, baby and incontinence skin
care sections.

         Professional Products. PMP continues to generate significant cash flow.
The Company is able to achieve significant margins on its prescription
pharmaceutical products without extensive advertising and promotion. Net product
sales of URISED(R), the leading prescription pharmaceutical product, more than
doubled for the year ended March 31, 1998, as compared to the year ended March
31, 1997. The Company believes this increase is a result of a reduction in the
supply of generic products in the marketplace. Professional products represents
one of the broadest lines of prescription urology products available (excluding
anti-infectives), including urinary analgesics, antispasmodics, topical
anesthetics and suppositories. URISED(R), CYSTOSPAZ(R) and CYSTOSPAZ-M(R)
analgesics and antispasmodics provide effective symptomatic relief for urinary
pain, burning and spasms.

Products Under Development

         The Company is currently developing new thermometry products and is
considering new urinary discomfort products in its AZO family.

Major Customers

         For the fiscal year ended March 31, 1996, total revenues from Mylan
Laboratories, Inc., McKesson Drug Company, Bergen Brunswig Drug Company and
Bristol-Myers Squibb were 12.9%, 11.7%, 10.8%, and 11.2%, respectively, of total
consolidated revenues. For the fiscal years ended March 31, 1998 and 1997, no
customer represented more than 10% of the Company's consolidated revenues.

Patents and Trade Secrets

         The Company has proprietary manufacturing processes and trade secrets
related to its in-house pharmaceutical production. The Company owns one patent
for the Flexible Tip Digital Thermometer with Fever Alarm(TM).

Manufacturing

         The Company's pharmaceutical products are currently manufactured
in-house and by others on its behalf. The Company purchases a majority of its
consumer healthcare products from other manufacturers.

                                       4
<PAGE>   5



         By April 1997, all of the steps to validate, manufacture and sell
pharmaceutical products made at the Company's Woburn facility were completed.
With receipt of an FDA Establishment Registration Number, in-house manufacturing
is now underway for several established products, including AQUACHLORAL(R),
B&O(R) and URISED(R). The Company's state-of-the-art automated suppository
machine forms, fills and seals automatically and the computer-controlled,
hands-off equipment provides improved manufacturing efficiency.

Government Regulation

         Political, economic and regulatory influences are resulting in
fundamental changes in the healthcare industry in the United States. The Company
anticipates that Congress and state legislatures will continue to review and
assess alternative healthcare delivery systems and payment methods. Sales of a
large portion of the Company's products depend to a significant extent on the
availability of reimbursement to the Company's customers by government and
private insurance plans.

         Any further reduction in the reimbursement provisions currently in
effect for the Company's diabetes supplies products which are reimbursable under
Medicare would reduce the Company's revenues and earnings.

         The production and marketing of the Company's products and its ongoing
research and development activities are subject to regulation by numerous
governmental authorities in the United States.The Company cannot predict the
extent to which government regulations or changes thereto might have an adverse
effect on the production and marketing of the Company's existing or future
products. Products that the Company may develop in the future may require
clearance by the Food and Drug Administration ("FDA") in the United States.
Although the Company believes each of these products, if successfully developed,
will obtain FDA clearance, no assurance can be made that each will obtain such
clearance, or that the process of clearance will be without undue delay or
expense.

         The Company is subject to numerous federal, state and local laws
relating to such matters as controlled drug substances, safe working conditions,
manufacturing practices, environmental protection, fire hazard control and
disposal of hazardous or potentially hazardous substances. For example, the Drug
Enforcement Administration ("DEA") regulates controlled drug substances, such as
narcotics, under the Controlled Substances Act and the Controlled Substances
Import and Export Act. Manufacturers, distributors and dispensers of controlled
substances must be registered and inspected by the DEA, and are subject to
inspection, labeling and packaging, export, import, security, production quota
and record keeping, and reporting requirements. The Company currently markets
two prescription drug products containing controlled drug subjects, and
therefore is subject to the DEA regulatory requirements. In addition, labeling
and promotional activities relating to medical devices and drugs are, in certain
instances, subject to regulations by the Federal Trade Commission. There can be
no assurance that the Company will not be required to incur significant costs to
comply with such laws and regulations in the future or that such laws or
regulations will not have a material adverse effect upon the Company's ability
to do business.

Competition

         The Company is engaged in rapidly evolving and highly competitive
fields. Many major pharmaceutical, medical product and personal care companies
in the United States and abroad seek to develop competitive products.
Competition from medical device manufacturers, pharmaceutical companies and
others is intense and expected to increase. Many of these companies have
substantially greater capital resources, research and development staffs and
facilities and experience in obtaining regulatory approvals, as well as in the
marketing and distribution of products, than the Company.

         In the diabetes supply market, Universal Self Care, Inc. and Transworld
Home Healthcare, Inc., are publicly-held companies which compete with Liberty
Medical in the direct-mail supply business. There are several smaller
privately-held companies which also compete in this market.

         In the consumer healthcare products market, the Company competes with
various other suppliers for retail shelf space and consumer purchase. While
there are numerous companies that manufacture and market consumer healthcare
products, the Company believes that no single company is readily identifiable by
consumers as a maker of products which attempt to detect or monitor medical
problems in the home. The Company believes that it offers consumers practical,
easy-to-use products at reasonable prices. In the urinary discomfort category,
the Company's AZO STANDARD(R) urinary analgesic is one of the category leaders.
Competitors include Numark Laboratories, Inc. (Cystex(TM)), Breckenridge
Pharmaceutical, Inc. (Prodium(TM)) and Johnson & Johnson (Uristat(TM)).

         In the professional market, numerous pharmaceutical companies develop
and market prescription products which compete with the Company's products on a
branded and generic basis. The Company's principal branded competitors include:
Astra USA, Inc.

                                       5

(Xylocaine(R) vs. ANESTACON(R)); G & W Labs, Inc. (chloral hydrate vs.
AQUACHLORAL(R)); Parke-Davis, a division of Warner-Lambert., (Pyridium(R) vs.
URISED(R)); Schwarz-Pharma (Levsin(TM) line vs. CYSTOSPAZ(R) line); and
Wyeth-Ayerst Laboratories, a division of American Home Products Corp.
(belladonna and opium vs. B&O(R) SUPPRETTES(R)).

Employees

         As of March 31, 1998, the Company had 349 full-time employees. The
Company expects to employ additional personnel as it expands its operations. The
Company believes that its relations with its employees are good.

ITEM 2.  PROPERTIES

         The Company's facilities are located in Woburn, Massachusetts; Palm
City and Stuart, Florida and Golden, Colorado. The Company's corporate
headquarters are located in Woburn in a 60,000 square foot facility which the
Company owns. The Company also leases approximately 50,000 square feet at its
facilities in Palm City and Stuart, Florida and approximately 30,000 square feet
at its Golden, Colorado facility.

         The Company believes that its current facilities will be adequate for
its current and anticipated needs.

ITEM 3.  LEGAL PROCEEDINGS

         The Company is not a party to any material legal proceedings.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         No matters were submitted to a vote of security holders of the Company,
through solicitations of proxies or otherwise, during the last quarter of the
fiscal year ended March 31, 1998.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED SHAREHOLDER MATTERS
         SELECTED FINANCIAL DATA

         At March 31, 1998, the Company's Common Stock was held by 514 holders
of record. The Company believes that the actual number of beneficial owners of
the Company's Common Stock is substantially greater than the stated number of
holders of record because a substantial portion of the Common Stock outstanding
is held in "street name."

         The following table sets forth the high and low sales price per share
of Common Stock on the American Stock Exchange:

         In connection with the distribution of CardioTech International, Inc.
shares to PolyMedica shareholders in June 1996, CardioTech's operations are
accounted for as discontinued operations in the Company's 1996 and prior
statements of operations.

         In 1997, the Company determined that it is more likely than not that
certain deferred tax assets will be realized and accordingly eliminated the
related valuation allowance. Realization of the net deferred tax assets is
dependent on generating sufficient taxable income prior to the expiration of
loss carryforwards. Although realization is not assured, management believes
that it is more likely than not that such net deferred tax assets will be
realized. As a result, the Company recorded a tax benefit in 1997.

         In 1998, net income included $2.74 million, or $0.29 per common share,
diluted, related to the gain on the July 1997 sale of the Company's wound care
business.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

FUTURE OPERATING RESULTS

         This Annual Report contains forward-looking statements. For this
purpose, any statements contained herein that are not statements of historical
fact may be deemed to be forward-looking statements. Without limiting the
foregoing, the words "believes", "anticipates", "plans", "expects", and similar
expressions are intended to identify forward-looking statements. There are a
number of important factors that could cause the Company's actual results to
differ materially from those indicated or suggested by such forward-looking
statements. These factors include, without limitation, those set forth below in
the section titled, "Factors Affecting Future Operating Results" in this Annual
Report.

OVERVIEW

Business

         PolyMedica is a leading provider of targeted medical products and
services primarily focused in the diabetes supplies and consumer healthcare
markets. PolyMedica sells diabetes supplies through its wholly-owned subsidiary
Liberty Medical Supply, Inc. Liberty Medical is a leading patient-focused,
direct-mail distributor of more than 200 name-brand diabetes products to
insulin-using, Medicare-eligible seniors with diabetes. PolyMedica also holds a
leading position in the over-the-counter urinary health market and distributes a
broad range of other medical products, including digital thermometers and
compliance products, primarily to food and drug retailers and mass merchandisers
nationwide. The Company also markets, manufactures and distributes a line of
prescription urological and suppository products.

         In September 1997, the Company changed its name from PolyMedica
Industries, Inc. to PolyMedica Corporation.

Diabetes Supplies

         Liberty Medical is the leading mail-order distributor of diabetes
testing supplies to patients who use insulin and have Medicare or private
insurance coverage. Liberty Medical provides a simple, reliable way for seniors
to obtain their diabetes testing supplies and the Medicare and insurance
benefits to which they are entitled. Liberty Medical offers a wide array of
products from a full range of name-brand manufacturers, contacts the patient's
doctor to obtain the required prescription information and written
documentation, files the appropriate insurance forms and bills Medicare and
private insurers directly. This service frees the patient from paying for his or
her diabetes-related upfront expenses, and offers the convenience of free home
delivery of supplies.

Consumer Healthcare

         The Company's consumer healthcare products are focused on three areas:
female urinary tract discomfort, digital thermometers and medication compliance
products. In the urinary tract discomfort area, the Company's two products are
AZO-STANDARD(R), which provides relief from urinary tract discomfort, and
AZO-CRANBERRY(R), a dietary supplement which helps maintain a healthy urinary
tract. During the three months ended March 31, 1998, the Company introduced AZO
TEST STRIPS(TM), an in-home urinary tract infection testing kit which allows
patients to call their doctors with testing results.

         The Company's consumer healthcare products also include digital,
digital flexible tip, basal and glass thermometers, as well as approximately 40
other home-use diagnostic and compliance products. PolyMedica has patented and
introduced a new flexible tip thermometer that became available for the
1997-1998 cough and cold season. The Company custom manufacturers and/or
distributes its other consumer healthcare products under private label and under
the brand names of BASIS(R), MEDI-AID(R), PolyMedica and PeeDee Dose(TM).

Professional Products

         PolyMedica's professional products represent one of the broadest lines
of prescription urology products excluding anti-infectives, available, including
urinary analgesics, anti-spasmodics, local anesthetics and suppositories.
URISED(R), CYSTOSPAZ(R) and CYSTOSPAZ-M(R) analgesics and anti-spasmodics
provide effective symptomatic relief for urinary pain, burning and spasms. Many
urology offices, as well as hospitals, purchase the local anesthetic
ANESTACON(R) for use in diagnostic procedures and the catheterization process.
B&O(R) and AQUACHLORAL(R) suppositories are used by patients unable to tolerate
oral dosages of systemic analgesics and sedatives.

Recent Transactions

         In May 1996, the Company's board of directors declared a stock dividend
for the purpose of making a distribution (the "Distribution") to the Company's
shareholders of all its shares of CardioTech International, Inc. ("CardioTech").
CardioTech's operations are accounted for as discontinued operations in the
Company's 1996 statements of operations, and accordingly, its operations are
segregated in the accompanying consolidated statements of operations for the
1996 and prior periods presented. Net sales, operating costs and expenses, and
other income and expense have been reclassified for amounts associated with
CardioTech's discontinued operations.

         In August 1996, the Company acquired all of the outstanding stock of
Liberty Medical in a transaction accounted for under the purchase method of
accounting. Accordingly, the net assets and operations of Liberty Medical have
been included in the Company's financial statements since the date of
acquisition.

         In July 1997, the Company sold certain assets of its U.S. and U.K.
wound care operations. Under the terms of the sale, the purchaser, Innovative
Technologies Group Plc ("IT"), paid the Company $9.00 million in cash and issued
to the Company an unsecured promissory note in the face amount of $4.00 million.
The Company could realize an additional $4.50 million if IT achieves certain
milestones, based on the performance of IT's stock and the performance of the
acquired business. The Company will recognize additional proceeds in excess of
the $9.00 million cash received only when and to the extent realized. The
Company's fiscal year ended March 31, 1998 statement of operations includes a
$4.13 million pretax gain on the sale of the wound care business.

Other

         Advertising, promotional, and other marketing costs are charged to
earnings in the period in which they are incurred. Promotional and sample costs
whose benefit is expected to assist future sales are expensed as the related
materials are used. In accordance with Statement of Position 93-7,
direct-response advertising and related costs for all periods presented are
capitalized and amortized to selling, general and administrative expense on an
accelerated basis during the first two years of a four-year period. The
amortization rate is such that 55% of such costs are expensed after two years
from the date they are incurred, and the remaining 45% is expensed on a straight
line basis over the next two years. Revenues generated from new customers as a
result of direct-response advertising have historically resulted in a revenue
stream lasting seven years. Management has selected a more conservative
four-year amortization period, in consideration of the "Factors Affecting Future
Operating Results" described herein. Management assesses the realizability of
the amounts of direct-response advertising costs reported as assets at each
balance sheet date by comparing the carrying amounts of such assets to the
probable remaining future net benefits expected to result directly from such
advertising.

         Although the use of certain of the Company's products is somewhat
seasonal in nature, the Company does not believe its net product sales, in the
aggregate, are generally subject to material seasonal fluctuations.

         The Company operates from manufacturing, distribution and research and
development facilities located in Massachusetts, Florida and Colorado. Virtually
all of the Company's product sales are denominated in U.S. dollars. The
Company's research and development activities are funded from ongoing operations
and relate to the manufacture of pharmaceutical products.

         Period to period comparisons of changes in net product sales are not
necessarily indicative of results to be expected for any future period.

RESULTS OF OPERATIONS

Year Ended March 31, 1998 Compared to Year Ended March 31, 1997

         Total revenues increased by 142.5% to $73.83 million in the fiscal year
ended March 31, 1998 as compared with $30.45 million in the fiscal year ended
March 31, 1997. This increase is primarily the result of the growth in Liberty
Medical revenues which were generated for the twelve months during the fiscal
year ended March 31, 1998.

         Net product sales of diabetes supplies were $48.71 million in the
fiscal year ended March 31, 1998. This performance compares with $8.65 million
in the fiscal year ended March 31, 1997 for the seven month period beginning
with the August 1996 acquisition of Liberty Medical by the Company. This growth
is largely a result of the Company's increased direct-response advertising
spending, including its initiation of television advertising at the end of the
fiscal year ended March 31, 1997. The Company currently expects its promotional
and direct-response advertising spending to continue in order to further the
expansion of Liberty Medical's customer base.

                                       11
<PAGE>   12


         Net product sales of consumer healthcare products increased by 8.3% to
$11.15 million in the fiscal year ended March 31, 1998 as compared with $10.30
million in the fiscal year ended March 31, 1997. Sales of advanced thermometry
products increased during the fiscal year ended March 31, 1998, offset by a
decline in sales of AZO STANDARD(R). The Company has added to its product line
by introducing its Flexible-Tip Digital Thermometer with Fever Alarm(TM) which
began shipping in August 1997. The Company believes that the decline in sales of
AZO STANDARD(R) experienced during the first nine months of the year ended March
31, 1998 was due to an inventory oversupply at the distribution level. As shown
by strong sales of AZO STANDARD(R) in the fourth quarter of the year ended March
31, 1998, the Company believes that the inventory oversupply has ended. In
addition, the Company introduced AZO TEST STRIPS(TM), an in-home urinary tract
infection testing kit which allows patients to call their doctors with testing
results. Shipments of AZO TEST STRIPS(TM) began during the three months ended
March 31, 1998.

         Net product sales of the Company's professional products increased by
21.4% to $13.97 million in the fiscal year ended March 31, 1998 as compared with
$11.51 million in the fiscal year ended March 31, 1997. Professional products
include a full year of wound care product sales in the fiscal year ended March
31, 1997. The 21.4% increase in professional products sales is primarily due to
additional shipments of URISED(R) in the fiscal year ended March 31, 1998, which
the Company believes is the result of a reduction in the supply of generic
products in the marketplace, partially offset by a lower level of wound care
related sales in the fiscal year ended March 31, 1998 due to the sale of certain
assets of the wound care division in July 1997.

         As a percentage of net product sales, overall gross margins were 51.8%
in the fiscal year ended March 31, 1998 and 54.5% in the fiscal year ended March
31, 1997. Gross margins in the fiscal year ended March 31, 1998 decreased due to
the inclusion of significant sales of diabetes-related products, whose gross
margins are lower than the Company average for products sold in the fiscal year
ended March 31, 1997, partially offset by improving margins and higher revenues
of professional products.

         As a percentage of total revenues, selling, general and administration
expenses ("SG&A expenses") were 38.7% for the fiscal year ended March 31, 1998
as compared with 40.4% for the fiscal year ended March 31, 1997. SG&A expenses
increased by 131.8% in the fiscal year ended March 31, 1998 to $28.55 million as
compared with $12.32 million in the fiscal year ended March 31, 1997. This
increase is primarily attributable to SG&A expenses related to the expansion of
Liberty Medical, and marketing and advertising costs related to its consumer
healthcare products.

         Research and development expenses were $280,000 in the fiscal year
ended March 31, 1998 as compared with $670,000 in the fiscal year ended March
31, 1997. This decrease in research and development costs is a result of the
Company's July 1997 sale of certain assets related to its wound care business.

         Investment income decreased by 27.2% to $629,000 in the fiscal year
ended March 31, 1998 as compared with $864,000 in the fiscal year ended March
31, 1997 as the Company earned interest on lower average cash balances in the
fiscal year ended March 31, 1998 due to cash paid for the purchase of Liberty
Medical in August 1996 and investments in direct-response advertising. This use
of cash was partially offset by cash received in July 1997 in connection with
the sale of certain assets related to the Company's wound care business.
Interest expense was $2.69 million in the fiscal year ended March 31, 1998 as
compared with $2.77 million in the fiscal year ended March 31, 1997, as the
Company accrued interest expense in both periods on Guaranteed Senior Secured
Notes due January 31, 2003 (the "Hancock Notes") to the John Hancock Mutual Life
Insurance Company ("Hancock").

         Pretax income was $11.49 million in the fiscal year ended March 31,
1998. Excluding the $4.13 million pretax gain described above, pretax income was
$7.36 million as compared with $1.96 million in the fiscal year ended March 31,
1997. The Company's net income was $7.62 million, or $0.79 per diluted common
share, in the fiscal year ended March 31, 1998. Excluding the $2.74 million
after tax gain from the sale of the wound care business, or $0.29 per diluted
common share, income was $4.88 million, or $0.50 per diluted common share. This
performance compares to net income of $2.32 million, or $0.27 per diluted common
share, in the fiscal year ended March 31, 1997.

Year Ended March 31, 1997 Compared to Year Ended March 31, 1996

         Total revenues increased by 23% to $30.45 million in the fiscal year
ended March 31, 1997 as compared with $24.76 million in the fiscal year ended
March 31, 1996.

         Net product sales of diabetic supplies were $8.65 million in the fiscal
year ended March 31, 1997, for the seven month period beginning with the August
1996 acquisition of Liberty Medical by the Company.

         Net product sales of consumer healthcare products increased by 16.7% to
$10.30 million in the fiscal year ended March 31, 1997 as compared with $8.82
million in the fiscal year ended March 31, 1996. Most of the increase in net
product sales in the fiscal year ended March 31, 1997 was due to increased
shipments of thermometry products and AZO STANDARD(R).


                                       12
<PAGE>   13


         Net product sales of professional products decreased by 29.5% to $10.93
million in the fiscal year ended March 31, 1997 as compared with $15.50 million
in the fiscal year ended March 31, 1996. Net product sales of prescription
urologicals, which comprised approximately two-thirds of professional product
sales, declined by 10.4% in the fiscal year ended March 31, 1997 as compared to
the fiscal year ended March 31, 1996. Net product sales of wound dressings
declined by 53.9% in the fiscal year ended March 31, 1997 as compared with the
fiscal year ended March 31, 1996. Net product sales of wound dressings
represented 10.5% of Company-wide net product sales as in the fiscal year ended
March 31, 1997 as compared with 28.0% in the fiscal year ended March 31, 1996.
This decline was primarily due to changes in Medicare reimbursement and resulted
in the early termination of the Company's MITRAFLEX(R) supply contract with
Bristol-Myers Squibb.

         Royalty, exclusivity, development and license fees increased by 31.7%
to $573,000 in the fiscal year ended March 31, 1997 as compared with $435,000 in
the fiscal year ended March 31, 1996. This increase is primarily due to the
inclusion in the fiscal year ended March 31, 1997 of a fee from Perstorp AB in
connection with the establishment of Perstorp as the exclusive pan-European
distributor of SPYROSORB(R), offset by a decline in royalties earned from
shipments of MITRAFLEX(R) by Bristol-Myers Squibb.

         As a percentage of net product sales, overall gross margins were 54.5%
in the fiscal year ended March 31, 1997 and 58.0% in the fiscal year ended March
31, 1996. Gross margins in the fiscal year ended March 31, 1997 decreased
primarily due to the inclusion of significant sales of diabetes related
products, whose gross margins are lower than the Company average for other
products in the fiscal year ended March 31, 1996.

         As a percentage of total revenues, SG&A expenses were 40.4% for the
fiscal year ended March 31, 1997 as compared with 36.3% for the fiscal year
ended March 31, 1996. SG&A expenses increased by 37.0% in the fiscal year ended
March 31, 1997 to $12.32 million as compared with $8.99 million in the fiscal
year ended March 31, 1996. This increase is primarily attributable to SG&A
expenses related to the expansion of Liberty Medical, and marketing and
advertising costs related to its consumer healthcare products.

         Research and development expenses increased by 3.2% to $670,000 in the
fiscal year ended March 31, 1997 as compared with $649,000 in the fiscal year
ended March 31, 1996.

         Investment income decreased by 3.1% to $864,000 in fiscal 1997 as
compared with $892,000 in the fiscal year ended March 31, 1996, as the Company
earned interest on lower average cash balances, in part due to the spinoff of
CardioTech and the purchase of Liberty Medical. Interest expense was $2.77
million in the fiscal year ended March 31, 1997, as compared with $2.68 million
in the fiscal year ended March 31, 1996, as the Company accrued and paid
interest expense in both periods on the Hancock Notes.

         The Company's net income increased to $2.32 million, or $0.27 per
diluted common share, in fiscal year ended March 31, 1997. This performance
compares to net income of $274,000, or $0.04 per diluted common share, reported
in the fiscal year ended March 31, 1996. Before taking into account the effect
of discontinued operations, income from continuing operations was $3.07 million,
or $0.41 per diluted common share in the fiscal year ended March 31, 1996. There
were no discontinued operations reported in the fiscal year ended March 31,
1997.

LIQUIDITY AND CAPITAL RESOURCES

         Since its inception, the Company has raised $53.46 million in gross
equity capital, of which $7.16 million was from venture capital financing before
the Company's initial public offering, $39.00 million from its March 1992
initial public offering, $4.55 million from a November 1995 public offering of
common stock and $2.75 million from a March 1996 private placement of common
stock. In January 1993, the Company sold to Hancock $25.00 million of Hancock
Notes.

         As of March 31, 1998, the Company had working capital of $21.07
million, including cash and cash equivalents of $6.44 million, which compares
with working capital of $14.63 million as of March 31, 1997. The primary reason
for the increase in working capital as of March 31, 1998, when compared to March
31, 1997, was the receipt by the Company in July 1997 of $9.00 million in cash
in connection with the sale of certain assets related to its wound care
business, and increased sales of diabetes supplies.

         Accounts receivable -- trade were $21.2 million and $6.2 million as of
March 31, 1998 and 1997, respectively. The increase is primarily a result of the
overall growth of Liberty Medical's sales in the fiscal year ended March 31,
1998, record shipments to new customers by Liberty Medical in December 1997
which required time to process, and delayed billing in the first six weeks of
calendar 1998. During the fiscal year ending March 31, 1999, the Company expects
days sales outstanding to decrease from the March 31, 1998 balance.

         The Company expects that its current working capital and funds
generated from future operations will be adequate to meet its liquidity and
capital requirements for current operations. In the event that the Company
undertakes to make acquisitions of 

                                       13
<PAGE>   14


complementary businesses, products or technologies, the Company may require
substantial additional funding beyond currently available working capital and
funds generated from operations. The Company is conducting an active search for
the strategic acquisition of complementary businesses, products or technologies
which leverage its marketing, sales and distribution infrastructure. The Company
currently has no commitments or agreements with respect to any such acquisition.

YEAR 2000 COMPLIANCE

         The Company has conducted a review of its computer systems to identify
the systems that are affected by the year 2000. The year 2000 problem is the
result of computer programs being written using two digits rather than four to
define the applicable year. The Company intends to upgrade its systems over the
next 12-18 months in an effort to make more detailed data available on a system
wide basis in a timely manner. Such costs will be capitalized and amortized over
the useful life of the new software. The Company believes that with
modifications to existing software and conversions, the year 2000 issue will not
pose significant operational problems for the Company's computer systems. The
Company will continue to address any further year 2000 issues and believes that
any costs relating to such issues will not be material to the Company's
financial condition or results of operations.

FACTORS AFFECTING FUTURE OPERATING RESULTS

         The statements contained in this Report that are not purely historical
are forward-looking statements within the meaning of Section 27A of the
Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934,
including, but not limited to, statements regarding the Company's expectations,
hopes, intentions or strategies regarding the future. Forward-looking statements
include, among others: statements regarding possible future expansion of
diabetes coverage under Medicare; statements regarding future benefits from the
Company's advertising and promotional expenditures; statements regarding future
product revenue levels; statements regarding product development, introduction
and marketing; and statements regarding future acquisitions. All forward-looking
statements included in this Report are based on information available to the
Company on the date hereof, and the Company assumes no obligation to update any
such forward-looking statements. It is important to note that the Company's
actual results could differ materially from those in such forward-looking
statements.

         The future operating results of the Company remain difficult to
predict. The Company continues to face many risks and uncertainties which could
affect its operating results, including without limitation, those described
below.

         Healthcare Reimbursement

         Political, economic and regulatory influences are resulting in
fundamental changes in the healthcare industry in the United States. The Company
anticipates that Congress and state legislatures will continue to review and
assess alternative healthcare delivery systems and payment methods. Sales of a
large portion of the Company's products depend to a significant extent on the
availability of reimbursement to the Company's customers by government and
private insurance plans.

         Any further reduction in the reimbursement provisions currently in
effect for the Company's diabetes supplies products which are reimbursable under
Medicare would reduce the Company's revenues and earnings.

         The processing of third-party reimbursements is a labor-intensive
effort, and delays in processing claims for reimbursement may increase working
capital requirements. Final determination of reimbursements are subject to audit
by Medicare. Medicare audits of the Company to date have not resulted in any
significant adjustments. Future audits may, however, result in retroactive
adjustments for past charges for products and services, and such adjustments
could affect the future operations and earnings of the Company. The Balanced
Budget Act of 1997 expands Medicare coverage to seniors with diabetes who do not
use insulin. Any delay in the expected July 1998 implementation of this
legislation would correspondingly delay the anticipated expansion of Liberty
Medical's market.

         Ability to Manage Growth

         The Company has expanded its operations rapidly, which has created
significant demands on the Company's systems, its administrative, operational,
development and financial personnel and its other resources. Additional
expansion by the Company may further strain the Company's management, financial
and other resources, including its working capital resources, as a result of
delays in processing claims for third-party reimbursement. Although the Company
has recently upgraded its systems and other steps have been taken to address
these issues, there can be no assurance that such steps will be effective.

                                       14
<PAGE>   15


         Direct-Response Advertising

         In accordance with Statement of Position 93-7, direct-response
advertising and related costs for all periods presented are capitalized and
amortized to selling, general and administrative expense on an accelerated basis
during the first two years of a four-year period. The amortization rate is such
that 55% of such costs are expensed after two years from the date they are
incurred. Revenues generated from new customers as a result of direct-response
advertising have historically resulted in a revenue stream lasting seven years.
Management has selected a more conservative four-year amortization period.
Management assesses the realizability of the amounts of direct-response
advertising costs reported as assets at each balance sheet date by comparing the
carrying amounts of such assets to the probable remaining future net benefits
expected to result directly from such advertising. The Company can expect
fluctuations in its advertising costs to attract and retain new customers. The
Company expects that it will continue to incur substantial direct-response
advertising and related costs in connection with the further expansion of its
diabetes supplies business.

         Competition

         The Company is engaged in rapidly evolving and highly competitive
fields. Competition from other sellers of diabetes supplies, manufacturers of
healthcare products, pharmaceutical companies and other competitors is intense
and expected to increase. Many of these companies have substantially greater
capital resources, research and development staffs, facilities and experience in
marketing and distribution of products than does the Company. There can be no
assurance that the Company's competitors will not succeed in developing products
and services that are more effective than any that are being developed or sold
by the Company.

         The Company believes that the principal competitive factors in the
healthcare products industry include the ability to identify and respond to
customer needs, quality and breadth of service and product offerings, price and
technical expertise. The Company believes that its ability to compete also
depends in part on a number of competitive factors outside its control,
including the ability to hire and retain employees, the development by others of
products and services that are competitive with the Company's products and
services, the price at which others offer comparable products and services and
the extent of its competitors' responsiveness to customer needs.

         Dependence on Reorders - Change in Demand for Diabetes Supplies

         The Company generally incurs negative cash flow with respect to the
first order for its diabetes supplies from a customer due primarily to customer
acquisition costs, including advertising and Medicare and secondary insurance
compliance costs. Accordingly, the profitability of the Company's diabetes
supplies business depends on recurring orders. Reorder rates are inherently
uncertain and are subject to several factors, many of which are outside of the
Company's control, including customer shifts to nursing homes or other forms of
managed care, customer mortality, changing customer preferences, general
economic conditions and customer satisfaction. Furthermore, efforts are underway
to improve treatment of, and to seek a cure for, diabetes. Significant
developments in either area could substantially reduce or eliminate the demand
for the diabetes supplies sold by the Company.

         Dependence on Suppliers

         The Company purchases several of its consumer healthcare products,
including its thermometers, from suppliers based in the People's Republic of
China, usually using molds and tooling owned by or committed exclusively to the
Company. To date, the Company has not experienced difficulties in obtaining
timely delivery from these suppliers. Although the Company believes there are
alternate sources available for these products, there can be no assurance that
the Company would be able to acquire products from other sources on a timely or
cost-effective basis in the event current foreign suppliers were unable to
supply these products on a timely basis.

         Although the Company has three long-term purchase contracts with
respect to its diabetes supplies business, it operates principally on a
purchase-order basis. Each of the Company's over-the-counter products for
urinary tract discomfort and urinary tract health is manufactured by a single
supplier. Some of the Company's professional products also are manufactured by
single suppliers. PolyMedica is currently taking steps to provide alternate
sources of supply for both of these lines of products, but such efforts are not
yet complete.

         Dependence on Single Manufacturing Facility for Professional Products

         A majority of the Company's professional products is manufactured at
its headquarters facility in Woburn, Massachusetts. While the Company maintains
business interruption insurance, any prolonged inability to utilize this
facility as a result of fire, natural disaster or other event would have a
material adverse effect on the Company's business, financial condition and
results of operations. The Company complies with Good Manufacturing Practices
("GMP") regulations, prescribed by the Food and Drug Administration ("FDA"), in
its internal manufacturing facilities. The FDA enforces the GMP regulations
through its plant inspection program. If the 

                                       15
<PAGE>   16

Company fails to comply with GMP regulations, the Company could be required to
make material expenditures and could experience manufacturing delays to return
to compliance.

         Product Liability

         The testing, manufacturing, marketing and sale of medical and consumer
products entail an inherent risk that product liability claims will be asserted
against the Company or its third-party distributors. Certain manufacturers of
healthcare products have been subjected to significant claims for damages
allegedly resulting from their products. The Company currently maintains product
liability insurance coverage which it believes to be adequate for its present
purposes, but there can be no assurance that in the future the Company will be
able to maintain such coverage on acceptable terms or that current insurance or
insurance subsequently obtained will provide adequate coverage against any or
all potential claims.

         Reliance on Distributors for Consumer Healthcare and Professional
Products; Limited Direct Marketing Experience

         The Company has a limited direct marketing and sales organization, and
relies on its current distributors, for the sale of consumer healthcare and
professional products. The Company's ability to sell its consumer healthcare and
professional products will depend in part on its ability to enter into marketing
and distribution agreements with pharmaceutical, medical device, personal care
and other distributors in the United States and other countries. If the Company
enters into any such agreements, there can be no assurance that the Company's
third-party distributors will be able to market the Company's products
effectively.

         Integration of Other Businesses, Products and Technologies

         As part of its growth strategy, the Company currently intends to expand
through the acquisition of other businesses, products and technologies. The
Company regularly reviews such potential acquisitions, some of which may be
material. There can be no assurance that the Company will successfully acquire
any businesses, products or technologies, or that any such acquired businesses,
products or technologies will be profitable. The Company does not currently have
any commitments or agreements with respect to any such acquisition.

         Government Regulation

         Political, economic and regulatory influences are resulting in
fundamental changes in the healthcare industry in the United States. The Company
anticipates that Congress and state legislatures will continue to review and
assess alternative healthcare delivery systems and payment methods. Sales of a
large portion of the Company's products depend to a significant extent on the
availability of reimbursement to the Company's customers by government and
private insurance plans.

         Any further reduction in the reimbursement provisions currently in
effect for the Company's diabetes supplies products which are reimbursable under
Medicare would reduce the Company's revenues and earnings.

         The processing of third-party reimbursements is a labor-intensive
effort, and delays in processing claims for reimbursement may increase working
capital requirements. Final determination of reimbursements are subject to audit
by Medicare. Medicare audits of the Company to date have not resulted in any
significant adjustments. Future audits may, however, result in retroactive
adjustments for past charges for products and services, and such adjustments
could affect the future operations and earnings of the Company. The Balanced
Budget Act of 1997 expands Medicare coverage to seniors with diabetes who do not
use insulin. Any delay in the expected July 1998 implementation of this
legislation would correspondingly delay the anticipated expansion of Liberty
Medical's market.

         Certain aspects of the Company's business are subject to federal and
state regulation. Federal regulation covers, among other things, reimbursement
for diabetes testing supplies and the manufacturing, distribution and sale of
the Company's drugs and medical devices. The Company believes that its
operations comply with applicable federal and state laws and regulations in all
material respects. However, changes in the law or new interpretations of
existing laws could have a material adverse effect on the market for the
Company's products and services on permissible activities of the Company, and
the relative costs associated with doing business.

REPORT OF INDEPENDENT ACCOUNTANTS



TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF POLYMEDICA CORPORATION:

         We have audited the accompanying consolidated balance sheets of
PolyMedica Corporation as of March 31, 1998 and 1997, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended March 31, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free from
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, based on our audit, the financial statements referred
to above present fairly, in all material respects, the consolidated financial
position of PolyMedica Corporation as of March 31, 1998 and 1997, and
consolidated results of its operations and its cash flows for each of the three
years in the period ended March 31, 1998, in conformity with generally accepted
accounting principles.

                             POLYMEDICA CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A.  NATURE OF BUSINESS:

         PolyMedica Corporation (the "Company") was incorporated as Emerging
Sciences, Inc. in Massachusetts on November 16, 1988, and commenced commercial
operations in October 1989. In July 1990, the Company changed its name to
PolyMedica Industries, Inc. In June 1996, the Company distributed to its
shareholders all of its shares of CardioTech International, Inc. ("CardioTech")
in a transaction that qualified as a tax free spinoff. In August 1996, the
Company purchased Liberty Medical Supply, Inc., a diabetes supply company. In
July 1997, the Company sold certain assets of its U.S. and U.K. professional
wound care operations. In September 1997, the Company changed its name to
PolyMedica Corporation. The Company and its subsidiaries operate from
manufacturing, distribution, and laboratory facilities located in Massachusetts,
Florida, and Colorado.

         The Company generates sales from Diabetic Supplies; Consumer
Healthcare, which includes OTC medical devices and urinary discomfort products;
and Professional Products, which include prescription urologicals.

B.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BASIS OF CONSOLIDATION

         The consolidated financial statements include the accounts of the
Company and its wholly-and majority-owned subsidiaries. All significant
intercompany balances and transactions have been eliminated in consolidation.

         The operations of CardioTech are accounted for as discontinued
operations in 1996, and accordingly, its operations are segregated in the
accompanying consolidated statements of operations for the 1996 period
presented. Net revenues, operating costs and expenses, and other income and
expense have been reclassified for amounts associated with CardioTech's
discontinued operations. See Note E.

USE OF ESTIMATES

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

EARNINGS PER COMMON SHARE

         In its fiscal quarter ended December 31, 1997, the Company adopted
Statement of Financial Accounting Standards No. 128, "Earnings per Share", which
modifies the calculation of earnings per share ("EPS"). The Standard replaced
the previous presentation of primary and fully diluted EPS to basic and diluted
EPS. Basic EPS excludes dilution and is computed by dividing income available to
common shareholders by the weighted average number of common shares outstanding
for the period. Diluted EPS includes the dilution of common stock equivalents,
and is computed similarly to fully diluted EPS pursuant to APB Opinion 15. All
prior periods presented have been restated to reflect this adoption. See Note M.

UNCERTAINTIES

         The Company is subject to risks common to companies in the healthcare
industry, including but not limited to, development by the Company or its
competitors of new technological innovations, dependence on key personnel,
protection of proprietary technology, receipt of third party health care
reimbursement, and compliance with FDA government regulations.

CASH AND CASH EQUIVALENTS

         The Company considers all highly liquid short-term investments
purchased with an initial maturity of three months or less to be cash
equivalents. The Company places its cash and cash equivalents with high credit
quality financial institutions.

                                       23

                             POLYMEDICA CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

INVESTMENTS

         In 1998 and 1997, the Company invested primarily in commercial paper
with initial maturities of 90 days or less and classifies all investments as
held-to-maturity. All investments held as of March 31, 1998 and 1997 have been
classified as cash equivalents and are carried at amortized cost which
approximates market value.

INVENTORIES

         Inventories are valued at the lower of cost (first-in, first-out
method) or market.

RESEARCH AND DEVELOPMENT

         Research and development costs are charged to expense as incurred.

INTANGIBLE ASSETS

         The Company capitalizes and includes in intangible assets the costs of
acquiring patents on its products, a customer list, a covenant-not-to-compete,
and goodwill, which is the cost in excess of the fair value of the net assets of
acquired companies and product lines. All amortization is computed on the
straight-line basis over the shorter of the economic life of the asset or the
term of the underlying agreement. Patents, a customer list, a
covenant-not-to-compete, and goodwill are amortized over seventeen, seven, ten,
and seven to thirty years, respectively.

LONG-LIVED ASSETS

         Management's policy is to evaluate the recoverability of its long-lived
assets when the facts and circumstances suggest that these assets may be
impaired. The test of such recoverability is a comparison of the book value of
the asset to expected cumulative (undiscounted) operating cash flows resulting
from the underlying asset over its remaining life. If the book value of the
long-lived asset exceeds undiscounted cumulative operating cash flows, the
write-down is computed as the excess of the asset over the present value of the
operating cash flow discounted at the Company's weighted average cost of capital
over the remaining amortization period.

MARKETING AND PROMOTIONAL COSTS

         Advertising, promotional, and other marketing costs are charged to
earnings in the period in which they are incurred. Promotional and sample costs
whose benefit is expected to assist future sales are expensed as the related
materials are used.

DIRECT-RESPONSE ADVERTISING

         In accordance with Statement of Position 93-7, direct-response
advertising and related costs for all periods presented are capitalized and
amortized to selling, general and administrative expense on an accelerated basis
during the first two years of a four-year period. The amortization rate is such
that 55% of such costs are expensed after two years from the date they are
incurred, and the remaining 45% is expensed on a straight line basis over the
next two years. Revenues generated from new customers as a result of
direct-response advertising have historically resulted in a revenue stream
lasting seven years. Management has selected a more conservative four-year
amortization period, in consideration of the "Factors Affecting Future Operating
Results" in Item 7 "Management's Discussion and Analysis of Financial Condition
and Results of Operations" in this Annual Report. Management assesses the
realizability of the amounts of direct-response advertising costs reported as
assets at each balance sheet date by comparing the carrying amounts of such
assets to the probable remaining future net benefits expected to result directly
from such advertising.

         The Company capitalized direct-response advertising of $11.70 million
and $1.74 million in 1998 and 1997, respectively. As of March 31, 1998 and 1997,
accumulated amortization was $2.54 million and $120,000, which resulted in a net
capitalized direct-response advertising asset of $10.90 million and $1.62
million, respectively. A total of $2.42 million and $120,000 in direct-response
advertising was amortized and charged to selling, general and administrative
expense in 1998 and 1997, respectively.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

OTHER ASSETS

         Other assets consist principally of senior debt issuance costs and
deposits for equipment yet to be placed in service. Senior debt issuance costs
are being amortized over ten years.

FOREIGN CURRENCY TRANSLATION

         In accordance with Statement of Financial Accounting Standards No. 52,
"Foreign Currency Translation", assets and liabilities of the Company's foreign
subsidiaries are translated into U.S. dollars using current exchange rates at
the balance sheet date, and revenues and expenses are translated at average
exchange rates prevailing during the period. The resulting translation
adjustments are recorded in a separate component of Shareholders' Equity. As
result of the inactivity of foreign subsidiaries caused by the sale of the U.S.
and U.K. wound care business in July 1997, all foreign currency translation
adjustments were expensed.

PROPERTY, PLANT, AND EQUIPMENT

         Property, plant, and equipment are recorded at cost. Depreciation is
computed using the straight-line method based on the estimated useful lives of
the various assets which range from five to twelve years. Amortization of
leasehold improvements is computed using the straight-line method based on
estimated useful lives or terms of the lease, whichever is shorter. Upon
retirement or disposal of fixed assets, the costs and accumulated depreciation
are removed from the accounts, and any gain or loss is reflected in income.
Expenditures for repairs and maintenance are charged to expense as incurred.
Construction in progress is not depreciated until placed in service.

INCOME TAXES

         The Company recognizes deferred tax assets and liabilities based on
temporary differences between the financial statements and tax basis of assets
and liabilities using enacted tax rates expected to be in effect when they are
realized.

REVENUE RECOGNITION

         For product sales, the Company recognizes revenue upon shipment.
Contracted development fees from corporate partners are recognized upon
completion of service or the attainment of technical benchmarks, as appropriate.
Royalty revenue from product sales is recognized based upon the terms of the
royalty agreement, principally upon sale by the Company's distributors to end
users.

         Included as reductions to gross accounts receivable -- trade are a
sales allowance for returned goods and an allowance for bad debts. The Company
recorded sales returns and bad debt write-offs of $5.13 million and $1.01
million in the fiscal years ended March 31, 1998 and 1997, respectively.

ACCOUNTING PRONOUNCEMENTS

         In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which establishes standards for reporting and display of comprehensive
income and its components (revenue, expenses, gains and losses) in a full set of
general-purpose financial statements. This statement requires the classification
of items of comprehensive income by their nature in a financial statement and
the accumulated balance of other comprehensive income separately from retained
earnings, additional paid-in capital and the equity section of the balance
sheet. Management has not yet evaluated the effects of this change on its
reporting of income. The Company will adopt SFAS No. 130 for its fiscal year
ending March 31, 1999.

         In June 1997, the FASB issued SFAS No. 131, "Disclosure about Segments
of an Enterprise and Related Information," which supercedes FASB Statement No.
14, "Financial Reporting for Segments of a Business Enterprise" and changes the
way public companies report information about operating segments. SFAS No. 131,
which is based on the management approach to segment reporting, establishes
requirements to report selected segment information quarterly and to report
entity-wide disclosures about products and services, major customers and the
material countries in which the entity holds assets and reports revenue.
Management is currently evaluating the effects of this change on its reporting
of segment information. The Company will adopt SFAS No. 131 for its fiscal year
ending March 31, 1999.

RECLASSIFICATIONS

         Certain amounts in the prior financial statements have been
reclassified to conform with the current year presentation.

C.  SALE OF WOUND CARE BUSINESS:

         In July 1997, the Company sold certain assets of its U.S. and U.K.
wound care operations. Under the terms of the sale, the purchaser, Innovative
Technologies Group Plc ("IT"), paid the Company $9 million in cash and issued to
the Company an unsecured promissory note in the face amount of $4 million. The
Company could realize an additional $4.5 million if IT achieves certain
milestones, based on the performance of IT's stock and the performance of the
acquired business. The Company will recognize as income additional proceeds in
excess of the $9 million cash received only when and to the extent realized. The
net book value of assets sold and pretax gain as a result of this transaction
were $4.9 million and $4.1 million, respectively. Gain on the sale for the year
ended March 31, 1998 was as follows:

     Gain on sale of wound care business                            $4,126
 
     Provision for income taxes related to gain                      1,390
                                                                     -----
     Gain on sale, net of income taxes                              $2,736
                                                                     =====
     Income per common share, diluted                               $  .29
                                                                     =====

D.  PURCHASE OF LIBERTY MEDICAL SUPPLY, INC.:

         On August 30, 1996, the Company acquired all of the outstanding stock
of Liberty Medical Supply, Inc. in a transaction accounted for under the
purchase method of accounting. Accordingly, the net assets and operations of
Liberty Medical have been included in the Company's financial statements since
the date of acquisition. The acquisition agreement, as amended on March 26,
1997, for an aggregate purchase price of $10.26 million (including $490,000 of
related expenses), which was comprised of (i) $7.35 million in cash, (ii)
two-year 7% subordinated promissory notes in the aggregate amount of $1.30
million and (iii) 224,400 shares of the Company's common stock.

         The purchase price was allocated to net assets acquired based on their
fair value at the date of acquisition, and the excess of the purchase price over
the fair value of the assets acquired was recorded as attributable to a customer
list ($1.82 million, to be amortized over seven years) and goodwill ($6.82
million, to be amortized over twenty years).

         If the acquisition had taken place at the beginning of the year ending
March 31, 1997, giving effect to adjustments for amortization of intangible
assets, interest income and interest expense for twelve months, the Company's
pro forma (unaudited) revenues, net income and net income per share for the
twelve months ended March 31, 1997 would have been $35.63 million, $2.50 million
and $.29, respectively. If the acquisition had taken place at the beginning of
the year ended March 31, 1996, the Company's pro forma revenues, net loss and
net loss per share for the twelve months ended March 31, 1996 would have been
$35.1 million, $228,000, and $.03, respectively.

E.  DISCONTINUED OPERATIONS:

         On March 1, 1996, the Company announced its strategic decision to
distribute to its shareholders all of its shares of CardioTech under a plan
which was approved by the Company's board of directors. In May 1996, the
Company's board of directors declared a stock dividend for the purpose of making
a distribution (the "Distribution") to the Company's shareholders of all of the
outstanding shares it owned in CardioTech. The Company believes that the
distribution of CardioTech Common Stock in the Distribution qualified as a
"tax-free" spinoff under Section 355 of the Internal Revenue Code of 1986, as
amended. CardioTech develops, manufactures and markets its polymer technologies
with particular emphasis on the development of implantable synthetic grafts for
a broad variety of applications, including vascular access grafts, peripheral
grafts and coronary artery bypass grafts.

         Discontinued operations as shown on the consolidated statement of
operations for the year ended March 31, 1996 reflect two components. Loss from
discontinued operations, or $923,000, includes all CardioTech operating losses
from April 1, 1995 through February 20, 1996, the date the Company's board of
directors voted to proceed with the spinoff. Loss on disposal of CardioTech, or
$1,878,000, principally includes operating losses from February 1996 through the
June 1996 spinoff date and outside professional fees and other costs related to
the spinoff.

                             POLYMEDICA CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

         Revenues and net loss for the fiscal year ended March 31, 1996 relating
to discoutinued operations, excluding loss on disposal, were $166,000 and
$983,000, respectively. Since CardioTech's inception, all facilities and support
services, including research and administrative support, have been provided by
the Company. In connection with the Distribution, CardioTech has entered into
the following agreements with the Company:

DISTRIBUTION AGREEMENT

         This agreement allocates the costs related to the implementation of the
Distribution between the Company and CardioTech and provides that each company
will share equally any liabilities under the federal and any state securities
laws incurred as a result of the Distribution to shareholders of the Information
Statement.

LICENSE AGREEMENT

         The Company has granted to CardioTech an exclusive, perpetual,
world-wide, royalty-free license for CardioTech to use all of the necessary
patent and other intellectual property owned by the Company in the implantable
devices and materials field (collectively, the "Licensed Technology"). The
Company, at its own expense, will file patent or other applications for the
protection of all new inventions formulated, made or conceived by the Company
during the term of the license that related to the Licensed Technology and all
such inventions will be part of the technology licensed to CardioTech.
CardioTech, at its own expense, will file patent or other applications for the
protection of all new inventions formulated, made, or conceived by CardioTech
during the term of the license that related to the Licensed Technology and all
such inventions shall be exclusively licensed to the Company for use by the
Company in fields other than the implantable devices and materials field.

F.  ACCOUNTS RECEIVABLE -- TRADE:

         As of March 31, 1998, Liberty Medical's gross unbilled receivables
included in accounts receivable -- trade were $10.82 million. The increase in
the unbilled receivables balance as of March 31, 1998 is primarily a result of
the overall growth of Liberty Medical's sales in the fiscal year ended March 31,
1998, record shipments to new customers by Liberty Medical in December 1997
which required time to process, and delayed billing in the first six weeks of
calendar 1998.

         Amortization expense from continuing operations associated with
intangible assets for the years ended March 31, 1998, 1997, and 1996, was
$2,279,000, $2,117,000, and $1,811,000, respectively.

J.  ACCRUED EXPENSES:

         As of March 31, 1997, accrued expenses included $460,000 of accrued
interest. As of March 31, 1998 and 1997, accrued expenses included $1.04 million
and $771,000 respectively, of accrued taxes.

K.  SENIOR DEBT:

         In connection with the purchase of the WEBCON product line, in January
1993, the Company and its wholly-owned subsidiary, PolyMedica Pharmaceuticals
(U.S.A.), Inc. ("PMP USA") sold to the John Hancock Mutual Life Insurance
Company ("Hancock"), $25 million 10.65% Guaranteed Senior Secured Notes due
January 31, 2003, and a warrant for the purchase of up to 500,000 shares of
common stock of the Company at $13.50 each (the "Hancock Notes"). The effective
interest rate of the Hancock Notes was 10.97%. Interest is payable
semi-annually. At that time, the warrant was valued at $725,000 and was recorded
as a discount to the Hancock Notes, to be amortized to expense over the life of
the Hancock Notes. The warrant was exercisable beginning in January 1994. The
Company recorded $89,000 of amortization expense each for the years ended March
31, 1998 and 1997. As of March 31, 1998 and 1997, there was $423,000 and
$511,000, respectively, of unamortized discount, netted against senior debt.

         Commencing on April 1, 1993, the Company and PMP USA are required to
maintain certain covenants, including certain financial ratios as described in
the loan documents. In addition, there are certain restrictions on the payment
of dividends by PMP USA to PolyMedica Corporation. Fees incurred in connection
with the Hancock Notes were $211,000, are classified as other assets, and are
being amortized over the ten year life of the Hancock Notes.

         In January 1996, the Company and Hancock signed an amendment to the
Hancock Notes. Under the terms of the amendment, scheduled semi-annual
repayments of principal commence at $1.00 million each in fiscal 1998, increase
to $2.08 million each beginning in January 2000 and are completed with a $7.50
million payment at January 31, 2003. Pursuant to the amendment, the exercise
price for the Hancock warrant, exercisable for 536,993 shares of common stock of
the Company, was reduced from $8.38 to $7.00 per share and the interest rate of
the Hancock Notes was increased from 10.65% to 10.9%. In addition, the Company
obtained less restrictive dividend terms and revised financial covenants. This
amendment resulted in a revaluation of the warrant to $623,000, which compared
with a $513,000 unamortized value on January 1, 1996. The difference of $110,000
was recorded to additional paid-in capital.

         As a result of a private placement of the Company's Common Stock in
March 1996 and the acquisition of Liberty Medical in August 1996, the exercise
price of the Hancock warrant was adjusted to $5.18 per share of common stock for
a total of 543,464 shares exercisable under the warrant.

         Under the terms of the Hancock Notes, Hancock has a security interest
in all of the assets of PMP USA and its subsidiary PolyMedica Pharmaceuticals
(Puerto Rico), Inc. ("PMP PR").

         The Hancock Notes are collateralized by all of the assets of PMP USA
and PMP PR, which amounted to approximately $44.9 million as of March 31, 1998.

         Interest expense recorded for the Hancock Notes was $2,634,000,
$2,725,000, and $2,678,000 in the years ended March 31, 1998, 1997, and 1996,
respectively.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

         Each holder of outstanding common stock has a preferred stock purchase
right (a "Right") for each share of common stock. Each Right entitles the holder
to purchase from the Company one one-hundredth of a share of Series A junior
participating preferred stock at a cash exercise price to be determined by the
board of directors. Initially, the Rights will be attached to all common stock
certificates and will not be exercisable. The Rights will become exercisable
upon the earlier of certain events, including an acquisition by a person or
group of 15% or more of the outstanding common stock (an "Acquiring Person"), or
the commencement of a tender offer or exchange offer that would result in an
Acquiring Person beneficially owning 15% or more of the outstanding common
stock.

         The Company will generally be entitled to redeem the Rights at $.01 per
share at any time until the tenth day following public announcement that a 15%
stock position has been acquired. The Rights will expire on January 23, 2002,
unless earlier redeemed or exchanged.

         Between June 1992 and May 1994, the Company's board of directors
authorized the purchase of up to an aggregate of 1,750,000 shares of the
Company's common stock on the open market, with any shares to be held in
treasury. As of March 31, 1998, cumulative purchases of common stock totalled
239,193 for an aggregate of $1.69 million. The purpose of this purchase program
is, in part, to provide shares of common stock for issuance pursuant to the 1992
Stock Purchase Plan and upon the exercise of the warrant issued to Hancock.

         In October 1994, the board of directors declared a 5% stock dividend
paid on October 28, 1994, to holders of record as of October 14, 1994. Earnings
per share for all periods presented have been restated to reflect the stock
dividend.

         During fiscal 1998, the Company determined that it is more likely than
not, that tax assets remaining on March 31, 1998 will be realized. Realization
of the net deferred tax assets is dependent on generating sufficient taxable
income prior to the expiration of loss carryforwards. Although realization is
not assured, management believes that it is more likely than not that such net
deferred tax assets will be realized. The following is a summary of the
significant components of the Company's deferred tax assets and liabilities as
of March 31, 1998 and 1997:

         Amounts due from Customer A were $13,000 as of March 31, 1997. As of
March 31, 1998 and 1997, the amounts due from Health Care Financing
Administration of the United States government related to Liberty Medical
revenues was $4.64 million and $1.08 million, respectively. For the fiscal years
ended March 31, 1998 and 1997, no customer represented more than 10% of the
Company's consolidated revenues.

Q.  STOCK OPTIONS:

         The Company issues stock options under two plans: the 1990 Stock Option
Plan (the "1990 Plan") and the 1992 Directors Stock Option Plan (the "Directors
Plan"). In addition, in connection with the acquisition of American CDI, Inc.,
the Company assumed American CDI, Inc.'s 1991 Stock Option Plan (the "CDI Plan")
(collectively, the "Plans").

         The 1990 Plan and the Directors Plan provide for the grant to certain
individuals of stock options to purchase up to 2,400,000 and 200,000,
respectively, of the Company's common stock. The CDI Plan, as assumed by the
Company, provided for the grant of 61,905 shares of the Company's common stock.
All share numbers for the Plans have been adjusted to reflect the 5% stock
dividend declared and paid in October 1994.

         Generally, when shares acquired pursuant to the exercise of incentive
stock options are sold within one year of exercise or within two years from the
date of grant, the Company derives a tax deduction measured by the amount that
the fair market value exceeds the option price at the date the options are
exercised. When non-qualified stock options are exercised, the Company derives a
tax deduction measured by the amount that the fair market value exceeds the
option price at the date the options are exercised.

Supplemental Disclosures for Stock-Based Compensation

         The Company applies APB Opinion No. 25 and related Interpretations in
accounting for the Plans. Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation," ("SFAS 123") issued in 1995, defined
a fair value method of accounting for stock options and other equity
instruments. Under the fair value method, compensation cost is measured at the
grant date based on the fair value of the award and is recognized over the
service period, which is usually the vesting period. The Company elected to
continue to apply the accounting provisions of APB Opinion No. 25 for stock
options. The required disclosures under SFAS 123 as if the Company had applied
the new method of accounting are made below.

Employee Stock Purchase Plan 

         In January 1992, the board of directors adopted the 1992 Employee Stock
Purchase Plan (the "1992 Plan"). Under the 1992 Plan, eligible employees of the
Company may purchase shares of common stock, through payroll deductions, at the
lower of 85% of fair market value of the stock at the beginning or the end of
the offering period. Shares are issued to participants twice a year after each
six-month offering period, which ends April 30 and October 31. The company
issued 34,810 and 17,958 in the years ended March 31, 1998 and 1997
respectively. The weighted average fair values of shares issued under the 1992
Plan during the years ended March 31, 1997 and 1996 were $2.06 and $1.79,
repectively.

         Had compensation cost for the Company's 1998 and 1997 stock option
grants been determined consistent with SFAS 123, the Company's net income and
net income per share would approximate the pro forma amounts below:


                                                         Net Income Per
                                      Net Income      Fully Diluted Share
                                      ----------      -------------------

        As reported:
             1998                       $7,619,000          $ .79
             1997                       $2,322,000          $ .27

        Pro forma:
             1998                       $7,003,000          $ .72
             1997                       $1,134,000          $ .13



         The effect of applying SFAS 123 in this pro forma disclosure are not
indicative of future amounts. SFAS 123 does not apply to awards made prior to
1995. Additional awards in future years are anticipated.

BORROWER" and PolyMedica is also referred to in the capacity of the "AGENT
BORROWER")

with all representations, covenants, warranties, defaults, rights, remedies,

         WHEREAS, each Principal Borrower has requested that the Lender
establish the loan arrangement (hereinafter, the "LOAN ARRANGEMENT") as set
forth in Article 2 herein, to be cross-guaranteed by each of the Principal
Borrowers;

         WHEREAS, each Principal Borrower acknowledges and agrees that the Loan
Arrangement is in the best interest and financial well-being of each Principal
Borrower and that they shall each be liable for any and all loans made under the
Loan Arrangement (whether or not the proceeds of any such loan are received by
that Principal Borrower) both as a Principal Borrower and as a Guarantor

<PAGE>   2



and that the Lender is relying on this representation as a material inducement
to establish the Loan Arrangement;

         WHEREAS, each Principal Borrower requests that as a convenience to the
Principal Borrowers, such loans as may be made under the Loan Arrangement be
directed to the Agent Borrower which will, in turn, distribute the proceeds
thereof to the respective Principal Borrowers;

         NOW THEREFORE, as an additional inducement for the Lender to establish
the Loan Arrangement and to direct such loans as may be made hereunder to the
Agent Borrower, as described above, each Principal Borrower covenants and agrees
as follows, and that all loans and advances made under the Revolving Credit
(defined below) are payable as provided herein.

                                   WITNESSETH:

ARTICLE 1 - AGENTED BORROWINGS

         1-1.     DESIGNATION OF AGENT BORROWER. Each Principal Borrower hereby
designates the Agent Borrower as the agent of that Principal Borrower to
discharge the duties and responsibilities of the Agent Borrower as provided
herein.

         1-2.     OPERATION OF LOAN ARRANGEMENT. (a) Except as otherwise
provided in this Article, loans and advances under the Loan Arrangement shall be
requested solely by the Agent Borrower as agent for each Principal Borrower.

                  (b) To the extent permitted by law, confirmatory assignments
of accounts and accounts receivable and remittances on accounts and accounts
receivable of the respective Principal Borrowers shall be provided to the Lender
or otherwise directed in accordance with the Lender's instructions given from
time to time to the Agent Borrower.

                  (c) Any advance which may be made by the Lender under the Loan
Arrangement and which is directed to the Agent Borrower is received by the Agent
Borrower in trust for that or those of the Principal Borrowers who are intended
to receive such advance; shall be held by the Agent Borrower in an account
separate from all other funds of the Agent Borrower; and shall not be commingled
with any other funds of the Agent Borrower. The Agent Borrower shall distribute
the proceeds of any such advances solely to the Principal Borrowers. Each
Principal Borrower shall be directly indebted to the Lender for each advance
distributed to that Principal Borrower by the Agent Borrower, together with all
accrued interest thereon, as if that amount had been advanced directly

                                        2


<PAGE>   3



by the Lender to that Principal Borrower (whether or not the subject advance was
based upon the accounts and/or inventory or other assets of the Principal
Borrower which actually received such distribution), in addition to which each
Principal Borrower shall be obligated to the Lender in that amount on account of
that Principal Borrower's respectively having guaranteed the Obligations.

                  (d) The Lender shall have no responsibility to inquire as to
the distribution of loans and advances made by the Lender through the Agent
Borrower as described herein.

         1-3.     CONTINUATION OF AUTHORITY OF AGENT BORROWER. The authority of
the Agent Borrower to request loans on behalf of, and to bind, the Principal
Borrowers, shall continue unless and until the Lender actually receives

                  (a) written notice of: (i) the termination of such authority,
         and (ii) the subsequent appointment of a successor Agent Borrower,
         which notice is signed by the respective Presidents of each Principal
         Borrower (other than the President of the Agent Borrower being
         replaced) then eligible for borrowing under the within Agreement; and

                  (b) written notice from such successive Agent Borrower (i)
         accepting such appointment; (ii) acknowledging that such removal and
         appointment has been effected by the respective Presidents of such
         Principal Borrowers eligible for borrowing under the within Agreement;
         and (iii) acknowledging that from and after the date of such
         appointment, the newly appointed Agent Borrower shall be bound by the
         terms hereof, and that as used herein, the term "Agent Borrower" shall
         mean and include the newly appointed Agent Borrower.

         1-4.     INDEMNIFICATION. The Agent Borrower and each Principal
Borrower respectively hereby indemnify, defend, and save and hold the Lender
harmless from and against any liabilities, claims, demands, expenses, or losses
made against or suffered by the Lender on account of, or arising out of, the
Loan Arrangement, the Lender's reliance upon loan requests made by the Agent
Borrower, or any other action taken by the Lender hereunder or under any of the
Lender's various agreements with the Agent Borrower and/or any Principal
Borrower and/or any other person arising under the loan arrangement contemplated
herein except for any liability, claim, demand, expense, or loss as to which a
final judicial determination is made and from which no appeal is available (in a

                                        3

proceeding in which the Lender has had an opportunity to be heard) that the
Lender had acted in a grossly negligent manner or with willful misconduct.

ARTICLE 2 - THE REVOLVING CREDIT.

         2-1.     ESTABLISHMENT OF REVOLVING CREDIT. (a) The Lender hereby
establishes a revolving line of credit (hereinafter, the "REVOLVING CREDIT") in
the Principal Borrowers' respective favor pursuant to which the Lender, subject
to, and in accordance with, the within Agreement, shall make loans and advances
and otherwise provide financial accommodations to and for the account of the
Principal Borrowers as provided herein. The amount available for any new loan or
advance requested hereunder shall be determined by the Lender by reference to
Availability (as defined below), as determined by the Lender from time to time
hereafter. All loans made by the Lender under this Agreement, and all of the
Principal Borrowers' other Obligations (as defined below) to the Lender under or
pursuant to this Agreement, are payable as set forth herein.

                  (b)      As used herein, the term "AVAILABILITY" refers at any
time to the lesser of (i) or (ii), below:
                           (i)      Up to the result of the following:

                                    MINUS

                                    (B)      The then unpaid principal balance

                                    MINUS

                                             to be issued or incurred, by the
                                             Lender for the account and/or the
                                             benefit of any Principal Borrower.

                           of cost or market after deducting all transportation,
                           processing, handling charges, and all "soft" costs
                           and expenses, subject to such inventory reserves as
                           the Lender may establish from time to time ).

                                    (D)      The aggregate principal amounts
                                             then undrawn on all outstanding
                                             L/C's issued or incurred, or caused
                                             to be issued or incurred, by the
                                             Lender for the account and/or the
                                             benefit of any Principal Borrower.

                  (c)      Availability shall be based upon Borrowing Base 
Certificates furnished as provided in Section 2-3(a), below.

                  (d)      The proceeds of borrowings under the Revolving Credit
shall be used solely for working capital purposes of the Principal Borrowers and
for such other purposes as may be permitted by the Lender. The Principal
Borrowers acknowledge and agree that each of them shall remain liable to the
Lender for the payment and performance of all Obligations under all
circumstances, which payment and performance shall continue to be secured by all
collateral security granted by the Principal Borrowers to the Lender.

         2-2.     ADVANCES IN EXCESS OF MAXIMUM LOAN EXPOSURE/RISKS OF VALUE. 
(a) The Lender does not have any obligation to make any loan or advance, or
otherwise to provide any credit for the benefit of any of the Principal
Borrowers such that the outstanding principal balance of the Loan Account
(defined below) and the aggregate Stated Amount would exceed Maximum Loan
Exposure. The making of loans, advances, and credits and the providing of
financial accommodations by the Lender in excess of Maximum Loan Exposure is for
the benefit of the Principal Borrowers and does not affect the obligations of
the Principal Borrowers hereunder; such loans constitute Obligations.

                                        5


<PAGE>   6



The making of any such loans, advances, and credits and the providing of
financial accommodations in excess of Maximum Loan Exposure on any one occasion
shall not obligate the Lender to make any such loans, credits, or advances or to
provide any financial accommodation on any other occasion nor to permit such
loans, credits, or advances to remain outstanding.

                  (b)      The Lender's reference to a given asset for
monitoring concerning the Lender's making of loans, credits, and advances and
the providing of financial accommodations under the Revolving Credit shall not
be deemed a determination by the Lender relative to the actual value of the
asset in question. All risks of the creditworthiness of all Accounts and
Accounts Receivable are and remain upon the Principal Borrowers. Reference by
the Lender to a particular Account owed by a particular Account Debtor for
guidance and/or monitoring shall not obligate the Lender to rely upon any other
Account owed by the same Account Debtor to be acceptable for lending or to
continue to rely upon that account. All risks of the saleability of any of the
Principal Borrower's Inventory are and remain upon the Principal Borrowers. All
Collateral (defined below) secures the prompt, punctual, and faithful
performance of the Obligations whether or not relied upon by the Lender in
connection with the making of loans, credits, and advances and the providing of
financial accommodations under the Revolving Credit.

         2-3.     PROCEDURES UNDER REVOLVING CREDIT.(a) The Agent Borrower may
request loans and advances under the Revolving Credit from time to time, in each
instance in accordance with such procedures as may from time to time be
acceptable to the Lender, each of which request will be accompanied by a
Borrowing Base Certificate furnished to the Lender setting forth the
Availability with particularity acceptable to the Lender in its reasonable
discretion.

                  (b)      The Lender, subject to the terms and conditions of
the within Agreement, will provide the Agent Borrower with the loan so
requested, as follows:

                           (i)      With respect to a Domestic Rate Loan
         (defined below), if such request is received by 1:00 PM on a Business
         Day (defined below), by the end of business on that Business Day. If
         such request is received after 1:00 PM on a Business Day, by the end of
         the then next Business Day. The Lender may revise the above schedule by
         which loans shall be made from time to time.

                                        6


<PAGE>   7



                           (ii)     With respect to a Libor Rate Loan (defined
         below), if such request is received on any Business Day, by the end of
         second Business Day thereafter. The Lender may revise the above
         schedule by which loans shall be made, from time to time.

                           (iii)    Provided that there is sufficient 
Availability to support the same, (but subject, however, to Subsection 2-3(e),
below (which deals with the effect of a Suspension Event)), a loan or advance
under the Revolving Credit so requested by the Agent Borrower shall be made by
the transfer of the proceeds of such loan or advance to an account maintained by
the Agent Borrower with the Lender or as otherwise instructed by the Agent
Borrower.

                           (iv)     A loan or advance shall be deemed to have 
been made under the Revolving Credit upon the charging of the amount of such
loan to the Loan Account and the distribution of the proceeds thereof in
accordance with ss.2.3(b)(iii).

                           (v)      There shall not be any recourse to, nor 
liability of, the Lender (except due to its own gross negligence or willful
misconduct) on account of any of the following:

                                    (A)     Any reasonable delay in the Lender's
         making of any loan or advance requested under the Revolving Credit.

                                    (B)     Any reasonable delay in the proceeds
         of any such loan or advance constituting collected funds.

                                    (C)     Any reasonable delay in the receipt,
         and/or any loss, of funds which constitute a loan or advance under the
         Revolving Credit, the wire transfer of which was properly initiated by
         the Lender in accordance with wire instructions provided to the Lender
         by the Agent Borrower.

                           (vi)     The Lender may rely on any request for a 
loan or advance or financial accommodation which the Lender, in good faith,
believes to have been made by a person duly authorized to act on behalf of the
Agent Borrower and may decline to make any such requested loan or advance or to
provide any such financial accommodation pending the Lender's being furnished
with such documentation concerning that person's authority to act as may be
satisfactory to the Lender.

<PAGE>   8



                  (c)      A request by the Agent Borrower for any financial
accommodation under the Revolving Credit or of the issuance of an L/C shall be
irrevocable and shall constitute certification by the Borrower that as of the
date of such request, each of the following is true and correct:

                                    (i)     There has been no material adverse 
         change in any Principal Borrowers' financial condition from the most
         recent financial information furnished the Lender pursuant to this
         Agreement (except as permitted hereunder).

                                    (ii)    Each Principal Borrower is in 
         compliance with, and has not breached any of, its covenants contained
         in this Agreement.

                                    (iii)   Each representation which is made 
         herein or in any of the Loan Documents (defined below) is then true and
         complete as of and as if made on the date of such request (except those
         made as of a specific date or which are inaccurate due to transactions
         permitted hereunder).

                                    (iv)    No Suspension Event (defined herein)
         is then extant.

                  (d)      All Principal Borrowers shall immediately become 
indebted to the Lender for the amount of all loans under or pursuant to this
Agreement when such loan is deemed to have been made.

                  (e)      Upon the occurrence from time to time of any
Suspension Event, the Lender may suspend the Revolving Credit immediately and
shall not be obligated, during such suspension, to make any loans or to provide
any financial accommodation hereunder.

                  (f)      (i)      The Agent Borrower may request that the
Lender issue L/C's for the account of a Principal Borrower. Each such request
shall be in such manner as may from time to time be acceptable to the Lender,
and which may include, without limitation, (A) telephone notice to such person
as may be designated by the Lender or (B) written notice.

                           (ii)     The Lender will issue any L/C so requested
by the Agent Borrower, provided that the aggregate Stated Amount, following the
requested issuance thereof, would not exceed the Availability and provided that
the L/C (if so issued) is in form satisfactory to the Lender.

                           (iii)    The Agent Borrower and Principal Borrower
shall execute such documentation to apply for and support the issuance of an L/C
as may be required by the Lender

                                        8

provided that, notwithstanding any integration clauses in such L/C
documentation, the terms of this Agreement shall govern any conflict with such
L/C documentation.

                  (g)      After notice to the Agent Borrower, the Lender,
without the request of the Agent Borrower, may advance under the Revolving
Credit any amount which any Principal Borrower is obligated to pay to the Lender
or for which any Principal Borrower or the Lender becomes obligated on account
of, or in respect to, any L/C. Such advance shall be made whether or not a
Suspension Event is then extant and even if such advance would result in the
Availability being exceeded. Such action on the part of the Lender shall not
constitute a waiver of the Lender's rights under Section 2-6(b), below.

         2-4.     THE LOAN ACCOUNT. (a) An account (hereinafter, the "LOAN 
ACCOUNT") shall be opened on the books of the Lender, in which Loan Account a
record shall be kept of all loans made by the Lender to the Agent Borrower or
any Principal Borrower under or pursuant to this Agreement and of all payments
thereon.

                  (b)      The Lender shall also keep a record (either in the
Loan Account or elsewhere, as the Lender may from time to time elect) of all
interest, fees, service charges, costs, expenses, and other debits owed the
Lender on account of the Obligations and of all credits against such amounts so
owed.

                  (c)      All credits against the Obligations shall be
conditional upon final payment to the Lender of the items giving rise to such
credits. The amount of any item credited against the Obligations which is
charged back against the Lender for any reason or is not so paid shall be a
Obligation and shall be added to the Loan Account, whether or not the item so
charged back or not so paid is returned.

                  (d)      Except as otherwise provided herein, all fees,
service charges, costs, and expenses for which any Principal Borrower is
obligated hereunder are payable on demand.

                  (e)      The Lender, without the request of the Agent Borrower
but after notice, may advance under the Revolving Credit any interest, fee,
service charge, or other payment to which the Lender is entitled from any
Principal Borrower pursuant hereto which is not paid when due or within any
grace period and may charge the same to the Loan Account notwithstanding that
such amount

                                        9


<PAGE>   10



so advanced may result in Availability's being exceeded. Such action on the part
of the Lender shall not constitute a waiver of the Lender's rights under Section
2-6(b), below. Any amount which is added to the principal balance of the Loan
Account as provided in this Subsection shall bear interest at the interest rate
applicable from time to time to the unpaid principal balance of the Loan
Account.

                  (f)      Any written statement rendered by the Lender to the
Agent Borrower concerning the Obligations shall be presumed correct and shall be
presumptively binding upon each of them unless the Agent Borrower provides the
Lender with written objection thereto within sixty (60) days from the receipt by
Agent Borrower of such statement, which written objection shall indicate, with
particularity, the reason for such objection. The Loan Account and the Lender's
books and records concerning the loan arrangement contemplated herein and the
Principal Borrowers' Obligations shall be prima facie evidence and proof of the
items described therein.

         2-5.     THE MASTER NOTE. The obligation to repay loans and advances
under the Revolving Credit, with interest as provided herein, shall be evidenced
by a note (hereinafter, the "MASTER NOTE") in the form of EXHIBIT 2-5, annexed
hereto, executed by the Agent Borrower and Principal Borrowers. Neither the
original nor a copy of the Master Note shall be required, however, to establish
or prove any Obligation. In the event that the Master Note is ever lost,
mutilated, or destroyed, the Agent Borrower and each Principal Borrower shall
upon written request certifying that the Master Note was lost, mutilated or
destroyed execute a replacement thereof and deliver such replacement to the
Lender.

         2-6.     PAYMENT OF LOAN ACCOUNT. (a) The Principal Borrowers may repay
all or any portion of the principal balance of the Loan Account from time to
time until the sooner of termination of the Revolving Credit (as to which, see
Article 13, below) or demand.

                  (b)      The Principal Borrowers, without notice or demand
from the Lender, shall pay the Lender that amount, from time to time, which is
necessary so that the principal balance of the Loan Account does not exceed
Availability. The Lender shall furnish the Agent Borrower with three (3)
Business Days notice of any such payment which may be required resulting from
the Lender's

                                       10

calculation of "Acceptable Accounts" based upon the exclusion set forth in
Section b(ii) of the definition of "Acceptable Accounts" contained in Article 4.

                  (c)      The Principal Borrowers shall repay the then entire
unpaid balance of the Loan Account upon the Termination Date.

         2-7.     INTEREST. (a) The unpaid principal balance of the Loan Account
shall bear interest, and shall be repaid, as set forth in Exhibit 2-7 annexed
hereto.

                  (b)      The Agent Borrower shall have such rights as are set
forth in EXHIBIT 2-7 to select and, as applicable, Convert Loans from one Type
of Loan to another Type of Loan.

                  (c)      (i)      Upon the occurrence of an Event of Default,
at the Lender's option, the Revolving Credit and all other amounts payable
hereunder or under any of the other Loan Documents shall bear interest payable
on demand at a rate per annum equal to four percent (4%) above the then
applicable highest rate of interest hereunder until such amount shall be paid in
full (after as well as before judgment) (the "Default Rate").

                           (ii)     In addition to other charges described in
the Loan Documents, and without derogating from the right of the Lender to
accelerate the Obligations upon the occurrence of an Event of Default, the
Principal Borrowers shall pay to the Lender a late charge equal to three (3%)
percent of any payment due under the Note which is not paid within ten (10) days
of the due date thereof.

         2-8.     CLOSING AND ADMINISTRATIVE FEES. (a) As compensation for the
Lender's commitment included herein to make loans and advances hereunder and as
compensation for the Lender's maintenance of sufficient funds available for such
purpose, the Lender shall have earned a CLOSING FEE (so referred to herein) of
$18,750.00, which fee shall be paid with the proceeds of the first advance made
under the Revolving Credit.

                  (b)      As additional compensation for the Lender's
commitment included herein to make loans and advances hereunder and as
compensation for the Lender's maintenance of sufficient funds available for such
purpose, the Principal Borrowers shall pay to Lender on the first (1st) Business
Day of each fiscal quarter of the Agent Borrower for the prior fiscal quarter
commencing April 1,

                                       11


<PAGE>   12



1998, a nonrefundable fee of three eighths percent (.375%) per annum
(hereinafter, the "Unused Line Fee") of the amount, if any, by which the average
daily Commitment for the quarterly period (or, in the case of the first such
payment, the period from the closing date such payment is due, and in the case
of the last such payment, the period from the last date such payment was due to
the Termination Date) then existing exceeds the average daily outstanding
principal balances of the aggregate of the Loan Account plus the Stated Amount
of L/C's over the quarterly period then ending.

                  (c)      The Principal Borrowers shall not be entitled to any
credit, rebate or repayment of any Closing Fee or Unused Line Fee previously
earned by the Lender pursuant to this Section notwithstanding any termination of
the within Agreement or suspension or termination of the Lender's obligation to
make loans and advances hereunder.

         2-9.     LENDER'S DISCRETION. Each reference in the Loan Documents to 
the Lender's exercise of discretion or the like shall be to the Lender's
exercise of its judgment, in good faith (which shall be presumed).

         2-10.    FEES FOR L/C'S. (a) Prior to the issuance of any L/C, the 
Principal Borrowers shall pay to the Lender a fee on account of such L/C based
upon the Lender's then current fee schedule for like L/C's.

                  (b)      In addition to the fee to be paid as provided in
Subsection (a), above, the Principal Borrowers shall pay to the Lender, on
demand, all issuance, processing, negotiation, amendment, and administrative
fees and other amounts on account of, or in respect to, each L/C, customarily
charged by the Lender.

         2-11.    CONCERNING L/C'S. (a) No L/C shall have an expiry which is 
later than the Termination Date, without the prior written consent of the
Lender.

                  (b)      None of the Lender, the Lender's correspondents, or
any advising, negotiating, or paying bank with respect to any L/C shall be
responsible in any way for:

                           (i)      the performance by any beneficiary under any
         L/C of that beneficiary's obligations to any Principal Borrower; or

                                       12


<PAGE>   13



                           (ii)     the form, sufficiency, correctness,
         genuineness, authority of any person signing; falsification; or the
         legal effect of; any documents called for under any L/C if (with
         respect to the foregoing) such documents on their face and in Lender's
         good faith and reasonable belief appear to be in order.

                  (c)      The Lender may honor, as complying with the terms of
any L/C and of any drawing thereunder, any drafts or other documents otherwise
in order, but signed or issued and in Lender's good faith, reasonable belief by
an administrator, executor, conservator, trustee in bankruptcy, debtor in
possession, assignee for the benefit of creditors, liquidator, receiver, or
other legal representative of the party authorized under such L/C to draw or
issue such drafts or other documents.

                  (d)      Unless otherwise agreed to, in the particular
instance, each of the Principal Borrowers hereby authorize any Lender to (i)
select an advising bank, if any; (ii) select a paying bank, if any; and (iii)
select a negotiating bank.

                  (e)      All directions, correspondence, and funds transfers
relating to any L/C are at the risk of the Principal Borrowers. The Lender shall
have discharged the Lender's obligations under any L/C which, or the drawing
under which, includes payment instructions, by the initiation of the method of
payment called for in, and in accordance with, such instructions (or by any
other commercially reasonable and comparable method). The Lender shall not have
any responsibility for any inaccuracy, interruption, error, or delay in
transmission or delivery by post, telegraph or cable, or for any inaccuracy of
translation, except due to its own gross negligence or willful misconduct.

                  (f)      The Lender's rights, powers, privileges and
immunities specified in or arising under this Agreement are in addition to any
heretofore or at any time hereafter otherwise created or arising, whether by
statute or rule of law or contract.

                  (g)      Except to the extent otherwise expressly provided
hereunder or agreed to in writing by the Lender and any of the Principal
Borrowers, the L/C will be governed by the Uniform Customs and Practice for
Documentary Credits, International Chamber of Commerce, Publication No. 500, and
any subsequent revisions thereof.

                  (h)      If after the date hereof any change in any law,
executive order or regulation, or any directive of any administrative or
governmental authority (whether or not having the force of

                                       13


<PAGE>   14



law), or in the interpretation thereof by any court or administrative or
governmental authority charged with the administration thereof, shall either:

                           (i)      impose, modify or deem applicable any
         reserve, special deposit or similar requirements against letters of
         credit heretofore or hereafter issued by the Lender or with respect to
         which the Lender has an obligation to lend to fund drawings under any
         L/C; or

                           (ii)     impose on the Lender any other condition or 
         requirements relating to any such letters of credit;

and the result of any event referred to in Subsection (i) or (ii), above, shall
be to increase the cost to the Lender of issuing or maintaining any L/C (which
increase in cost shall be the result of the Lender's reasonable allocation among
the Lender's letter of credit customers of the aggregate of such cost increases
resulting from such events), then, upon demand by the Lender and delivery by the
Lender to a Principal Borrower of a certificate of an officer of the subject
Lender describing such change in law, executive order, regulation, directive, or
interpretation thereof, its effect on the Lender, and the basis for determining
such increased costs and their allocation, the Principal Borrowers shall
immediately pay to the Lender, from time to time as specified by the Lender,
such amounts as shall be sufficient to compensate such Lender for such increased
cost. Any determination by the Lender of costs incurred under Subsection (i) or
(ii) above, and the allocation, if any, of such costs among the Principal
Borrowers and other letter of credit customers of the Lender, if done in good
faith and made on an equitable basis and in accordance with the officer's
certificate, shall be conclusive and binding on the Principal Borrowers subject
to manifest error.

                  (i)      The obligations of the Principal Borrowers under the
within Agreement with respect to L/C's are absolute, unconditional, and
irrevocable and shall be performed in accordance with the terms hereof under all
circumstances, whatsoever including, without limitation, the following:

                           (i)      Any lack of validity or enforceability or
         restriction, restraint, or stay in the enforcement of the within
         Agreement, any L/C, or any other agreement or instrument relating
         thereto.

                                       14


<PAGE>   15



                           (ii)     Any amendment or waiver of, or consent to 
         the departure from, any L/C.

                           (iii)    The existence of any claim, set-off,
         defense, or other right which the Borrower may have at any time against
         the beneficiary of any L/C.

                           (iv)     Any honoring of a drawing under any L/C,
         which drawing possibly could have been dishonored based upon a strict
         construction of the terms of the L/C.

         2-12.    CHARGING OF THE PRINCIPAL BORROWERS' ACCOUNTS. In addition to
the Lender's rights set forth in Section 2-4, above, and the Lender's right of
set off set forth in Section 14-14, below, each Principal Borrower authorizes
the Lender, after notice (except after Event of Default when no such notice is
required), to charge any account which any Principal Borrower maintains with the
Lender for any payments due from the Principal Borrowers to the Lender on
account of the Obligations.

         2-13.    ADDITIONAL COSTS, ETC. If any change after the date hereof of
any present or adoption of any future applicable law, which expression, as used
herein, includes statutes, rules and regulations thereunder and interpretations
thereof by any competent court or by any governmental or other regulatory body
or official charged with the administration or the interpretation thereof and
requests, directives, instructions and notices at any time or from time to time
hereafter made upon or otherwise issued to the Lender by any central bank or
other fiscal, monetary or other authority (whether or not having the force of
law), shall:

                  (a)      subject the Lender to any tax, levy, impost, duty,
         charge, fee, deduction or withholding of any nature with respect to
         this Agreement, the other Loan Documents, or the Loans (other than
         taxes based upon or measured by the income or profits of the Lender),
         or

                  (b)      materially change the basis of taxation (except for
         changes in taxes on income or profits) of payments to the Lender of the
         principal of or the interest on any Loans or any other amounts payable
         to the Lender under this Agreement or the other Loan Documents, or

                  (c)      impose or increase or render applicable (other than
         to the extent specifically provided for elsewhere in this Agreement)
         any special deposit, reserve, assessment, liquidity, capital adequacy
         or other similar requirements (whether or not having the force of law)

                                       15


<PAGE>   16



         against assets held by, or deposits in or for the account of, or loans
         by, or commitments of an office of the Lender, or

                  (d)      impose on the Lender any other conditions or
         requirements with respect to this Agreement, the other Loan Documents,
         the Loan, or any class of loans or commitments of which any Loan forms
         a part; 

and the result of any of the foregoing is

                  (i)      to increase the cost to the Lender of making,
funding, issuing, renewing, extending or maintaining any of the Loans, or

                  (ii)     to reduce the amount of principal, interest or other
amount payable to the Lender hereunder on account of any of the Loans, or

                  (iii)    to require the Lender to make any payment or to
         forego any interest or other sum payable hereunder, the amount of which
         payment or foregone interest or other sum is calculated by reference to
         the gross amount of any sum receivable or deemed received by the Lender
         from the Principal Borrowers hereunder,

then, and in each such case, the Principal Borrowers will, upon demand made by
the Lender at any time and from time to time and as often as the occasion
therefor may arise, pay to the Lender such additional amounts as will be
sufficient to compensate the Lender for such additional cost, reduction, payment
or foregone interest or other sum incurred by Lender with respect to this
Agreement.

         2-14.    CAPITAL ADEQUACY. If the Lender shall have determined that the
adoption after the date hereof of any applicable law, rule, regulation,
guideline, directive or request (whether or not having force of law) regarding
capital requirements, or the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Lender with any
of the foregoing imposes or increases a requirement by the Lender to allocate
capital resources to the Loans made, or to be made, hereunder, which has or
would have the effect of reducing the return on the Lender's capital to a level
below that which the Lender could have achieved (taking into consideration the
Lender's then existing policies with respect to capital adequacy and assuming
full utilization of the Lender's capital) but for such adoption, change or
compliance, by any amount deemed by the Lender to be

                                       16


<PAGE>   17



material: (i) the Lender shall promptly after its determination of such
occurrence give notice thereof to the Agent Borrower; and (ii) the Principal
Borrowers shall pay to the Lender as an additional fee from time-to-time on
demand such amount as the Lender certifies to be the amount that will compensate
it for such reduction absent manifest error. In determining such amounts, the
Lender may use any reasonable averaging and attribution methods.

defined in the section of the within Agreement so indicated:

         "ACCEPTABLE ACCOUNTS": (a) Such of the Principal Borrowers' Accounts
                  and Accounts Receivable (as defined below) as arise in the
                  ordinary course of the Principal Borrowers' business for goods
                  sold and/or services rendered by the Principal Borrowers,

irrevocable until this Agreement is terminated by a written instrument executed
by a duly authorized officer of the Lender. The Lender shall not be liable on
account of any exercise pursuant to said power except for any exercise in actual
willful misconduct and bad faith. The Lender may apply any proceeds of such
insurance against the Obligations, whether or not such have matured, in such
order of application as the Lender may determine.

the Lender's discretion, may deem necessary or desirable, to protect, maintain,
preserve, collect, or realize upon any or all of the Collateral or the value
thereof or any right or remedy pertaining thereto, provided, however, the
Lender's making of any such payment shall not constitute a cure or waiver of any
Event of Default occasioned by any Principal Borrower's failure to have made
such payment.

purpose of purchasing or carrying any such margin stock.

vessel.

and is in compliance with all Environmental Laws.

                  (c)      Each Principal Borrower shall provide the Lender with
written notice upon any Principal Borrower's obtaining knowledge of any

liable.

         employees, and salespersons with respect to reasonable expenses to be
         incurred by such officers, employees, and salespersons for the benefit

         Principal Borrower.

                  (c)      Loans to any other Principal Borrower with the prior
         written consent of the Lender or which may be otherwise permitted under

and from time to time, may discharge any tax or Encumbrance on any of the
Collateral, or take any other action that the Lender may deem necessary or
desirable to repair, insure, maintain, preserve, collect, or realize upon any of
the Collateral. The Lender shall not have any obligation to undertake any of the
foregoing and shall have no liability on account of any action so undertaken
except where there is a specific finding in a judicial proceeding (in which the
Lender has had an opportunity to be heard), from which finding no further appeal
is available, that Lender had acted in actual bad faith or in a grossly
negligent manner. Each Principal Borrower shall pay to the Lender, on demand, or
the Lender, in its discretion, may add to the Loan Account, all amounts paid or
incurred by the Lender pursuant to this section. The obligation of each
Principal Borrower to pay such amounts is an Obligation.

         6-21.    LINE OF BUSINESS. No Principal Borrower shall engage in any
business other than the business in which it is currently engaged or a business
reasonably related thereto.

         amended; or

                                       42


<PAGE>   43



                  (b)      not differ from that which would have been charged in
         an arms length transaction.

         6-23.    ADDITIONAL ASSURANCES. (a) No Principal Borrower is the owner
of, nor has it any interest in, any property or asset which, immediately upon
the satisfaction of the conditions precedent to the effectiveness of the loan
arrangement contemplated hereby (Article 5), will be not be subject to a
perfected security interest in favor of the Lender (subject only to those
Encumbrances (if any) described on EXHIBIT 6-6, annexed hereto or to the extent
prohibited by law) to secure the Obligations and will not hereafter acquire any
asset or any interest in property which is not, immediately upon such
acquisition, subject to such a perfected security interest in favor of the
Lender to secure the Obligations (subject only to Encumbrances (if any)
permitted pursuant to Section 6-6, above).

                  (b)      Each Principal Borrower shall execute and deliver to
the Lender such instruments, documents, and papers, and shall do all such things
from time to time hereafter as the Lender may reasonably request to carry into

Lender's security interest in the Collateral; and to comply with all applicable
statutes and laws. Each Principal Borrower shall execute all such instruments as
may be required by the Lender with respect to the recordation and/or perfection
of the security interests created herein. A carbon, photographic, or other
reproduction of this Agreement or of any financing statement or other instrument
executed pursuant to this Section shall be sufficient for filing to perfect the
security interests granted herein.

         6-24.    ADEQUACY OF DISCLOSURE. (a) All financial statements furnished
to the Lender by any Principal Borrower have been prepared in accordance with
GAAP consistently applied and present fairly the condition of that Principal
Borrower at the date(s) thereof and the results of operations and cash flows for
the period(s) covered subject to footnotes and year end adjustments. There has
been no change in the financial condition, results of operations, or cash flows
of the Principal Borrower since the date(s) of such financial statements, other
than changes in the ordinary course of business, which changes have not been
materially adverse, either singularly or in the aggregate.

given the Lender by or on behalf of any Principal Borrower or any guarantor of
the Obligations in connection with the Lender's execution of the within
Agreement contains or will contain any untrue statement of a material fact or
omits or will omit to state a material fact necessary in order to make the
statements therein not misleading. There is no fact known to any Principal
Borrower which has, or which, in the foreseeable future could have, a material
adverse effect on the financial condition of any Principal Borrower or any such
guarantor which has not been disclosed in writing to the Lender or in
PolyMedica's periodic reports filed pursuant to the requirements of the
Securities Exchange Act of 1934, as amended, which have been provided to Lender.

         6-25.    OTHER COVENANTS. No Principal Borrower shall indirectly do or 
cause to be done any act which, if done directly by any of the Principal
Borrowers, would breach any covenant contained in this Agreement.

business practice, provided, however the authority granted each Principal
Borrower pursuant to this Section may be limited or terminated by the Lender at
any time in the Lender's discretion while an Event of Default is continuing.

         7-2.     VALIDITY OF ACCOUNTS. (a) To the best knowledge of the
Principal Borrowers, the amount of each Account shown on the books, records, and

and will be the correct amount actually owing by such Account Debtor and shall
have been fully earned by performance by that Principal Borrower.

                  (b)      The Lender, from time to time (at the expense of the
Principal Borrowers in each instance), may upon prior written or telephonic or
facsimile notice to the Agent Borrower (with no notice required if Event of
Default has occurred and is continuing) verify the validity, amount, and all
other matters with respect to the Receivables Collateral directly with Account
Debtors (including without limitation, by forwarding balance verification
requests to each Principal Borrower's Account Debtors), and with each Principal
Borrower's accountants, collection agents, and computer service bureaus (each of
which is hereby authorized and directed to cooperate in full with the Lender and
to provide the Lender with such information and materials as the Lender may
request.

                  (c)      No Principal Borrower has knowledge of any impairment

Lender of any such fact immediately after any Principal Borrower becomes aware
of any such impairment.

                  (d)      No Principal Borrower shall, other than in the
ordinary course of business, post any bond to secure that Principal Borrower's
performance under any agreement to which that Principal Borrower is a party nor
cause any surety, guarantor, or other third party obligee to become liable to
perform any obligation of that Principal Borrower (other than to the Lender) in
the event of that Principal Borrower's failure so to perform.

         7-3.     NOTIFICATION TO ACCOUNT DEBTORS. The Lender shall have the 
right at any time after an Event of Default has occurred to notify any of the
Principal Borrowers' Account Debtors to make payment directly to the Lender and
to collect all amounts due on account of the Collateral.

         7-4.     INVENTORY QUALITY. All Inventory now owned or hereafter
acquired by any Principal Borrower is and will be of good and merchantable
quality and free from defects (other than defects within customary trade
tolerances). No tangible personal property of any Principal Borrower is or will
be stored or entrusted with a bailee or other third party.

         7-5.      USE OF INVENTORY COLLATERAL. (a) No Principal Borrower shall
engage in any sale of the Inventory other than for fair consideration in the

not engage in sales or other dispositions to creditors; sales or other

                                       45

provision of this Agreement.

                           (b)      No sale of Inventory shall be on 
consignment, approval, or under any other circumstances such that, such
Inventory may be returned to the Principal Borrowers without the consent of the
Lender.

the Lender with written notice promptly upon the occurrence of any event

Inventory to the extent the value of such Inventory exceeds $100,00.00 for any
single transaction:

         Principal Borrower (whether or not such return has been agreed to by
         that Principal Borrower) and is not in turn returned by that Principal
         Borrower to such Account Debtor.

                  (ii)     Any which is repossessed by any Principal Borrower.

                  (iii)    Any which is downgraded in quality or has its

         required to be removed from the United States by the appropriate 
         governmental authorities.

ARTICLE 8 - LENDER AS BORROWER'S ATTORNEY-IN-FACT.

         8-1.     APPOINTMENT AS ATTORNEY-IN-FACT. Following and during the

Event of Default, any and all Obligations of the Principal Borrowers to the
Lender shall become immediately due and payable, at the option of the Lender and
without any further notice or demand. The occurrence of any Event of Default
shall also constitute, without notice or demand, a default under all other Loan
Documents between the Lender and each Principal Borrower and instruments and
papers given the Lender by any Principal Borrower, whether such agreements,
instruments, or papers now exist or hereafter arise, in connection herewith.

         10-1.    FAILURE TO PAY REVOLVING CREDIT. The failure by the Agent

process having the force of law, the effect of which is to restrain in any
material way the conduct by any Principal Borrower of its business in the

any of the Lender's Rights or Remedies, and no express or implied agreement or
transaction of whatever nature entered into between the Lender and any person,
at any time, shall preclude the other or further exercise of the Lender's Rights
and Remedies. No waiver by the Lender of any of the Lender's Rights and Remedies
on any one occasion shall be deemed a waiver on any subsequent occasion, nor
shall it be deemed a continuing waiver. All of the Lender's Rights and Remedies
and all of the Lender's rights, remedies, powers, privileges, and discretions
under any other agreement or transaction are cumulative, and not alternative or
exclusive, and may be exercised by the Lender at such time or times and in such

officer of the Lender.

ARTICLE 14 - GENERAL.

         14-1.    PROTECTION OF COLLATERAL. The Lender shall have no duty as to
the collection or protection of the Collateral beyond the safe custody of such
of the Collateral as may come into the possession of the Lender and shall have
no duty as to the preservation of rights against prior parties or any other
rights pertaining thereto.

         14-2.    SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon
the Agent Borrower, each Principal Borrower and their respective
representatives, successors, and assigns and shall enure to the benefit of the
Lender and the Lender's successors and assigns provided, however, no trustee or
other fiduciary appointed with respect to any Principal Borrower shall have any
rights hereunder. In the event that the Lender assigns or transfers its rights
under this Agreement, the assignee shall thereupon succeed to and become vested
with all rights, powers, privileges, and duties of the Lender

                                       60


<PAGE>   61



hereunder and the Lender shall thereupon be discharged and relieved from its
duties and obligations hereunder.

         14-3.    SEVERABILITY. Any determination that any provision of this
Agreement or any application thereof is invalid, illegal, or unenforceable in
any respect in any instance shall not affect the validity, legality, or
enforceability of such provision in any other instance, or the validity,
legality, or enforceability of any other provision of this Agreement.

         14-4.    AMENDMENTS. COURSE OF DEALING. (a) This Agreement and the
other Loan Documents incorporate all discussions and negotiations between the
Agent Borrower, each Principal Borrower and the Lender, either express or
implied, concerning the matters included herein and in such other instruments,
any custom, usage, or course of dealings to the contrary notwithstanding. No
such discussions, negotiations, custom, usage, or course of dealings shall
limit, modify, or otherwise affect the provisions thereof. No failure by the
Lender to give notice to the Agent Borrower or Principal Borrower or either of
them having failed to observe and comply with any warranty or covenant included
in any Loan Document shall constitute a waiver of such warranty or covenant or
the amendment of the subject Loan Document.

                  (b)      No consent, modification, amendment, or waiver of any
provision of any Loan Document shall be effective unless executed in writing by
or on behalf of the party to be charged with such modification, amendment, or
waiver (and if such party is the Lender, then by a duly authorized officer
thereof). Any modification, amendment, or waiver provided by the Lender shall be
in reliance upon all representations and warranties theretofore made to the
Lender by or on behalf of the Principal Borrowers (and any guarantor, endorser,
or surety of the Obligations) and consequently may be rescinded by the Lender in
the event that any of such representations or warranties was not true and
complete in all material respects when given.

         14-5.    POWER OF ATTORNEY. Upon and during continuance of an Event of 
Default, in connection with all powers of attorney included in this Agreement,
each Principal Borrower hereby grants unto the Lender full power to do any and
all things necessary or appropriate in connection

                                       61


<PAGE>   62



with the exercise of such powers as fully and effectually as that Principal
Borrower might or could do, hereby ratifying all that said attorney shall do or
cause to be done by virtue of this Agreement. No power of attorney set forth in
this Agreement shall be affected by any disability or incapacity suffered by any
Principal Borrower and each shall survive the same. All powers conferred upon
the Lender by this Agreement, being coupled with an interest, shall be
irrevocable until this Agreement is terminated by a written instrument executed
by a duly authorized officer of the Lender.

         14-6.    APPLICATION OF PROCEEDS. The proceeds of any collection, sale,
or disposition of the Collateral, or of any other payments received hereunder,
shall be applied toward the Obligations in such order and manner as the Lender
determines in its sole discretion. Each Principal Borrower shall remain liable
to the Lender for any deficiency remaining following such application.

         14-7.    LENDER'S COSTS AND EXPENSES. Each Principal Borrower shall pay
on demand all Costs of Collection and all reasonable expenses of the Lender in
connection with the preparation, execution, and delivery of this Agreement and
of any other Loan Documents, whether now existing or hereafter arising, and all
other reasonable expenses which may be incurred by the Lender in preparing or
amending this Agreement and all other agreements, instruments, and documents
related thereto, or otherwise incurred with respect to the Obligations. Upon
prior notice to the Principal Borrowers, each Principal Borrower specifically
authorizes the Lender to pay all such fees and expenses and in the Lender's
discretion, to add such fees and expenses to the Loan Account.

         14-8.    COPIES AND FACSIMILES. This Agreement and all documents which
relate thereto, which have been or may be hereinafter furnished the Lender may
be reproduced by the Lender by any photographic, microfilm, xerographic, digital
imaging, or other process, and the Lender may destroy any document so
reproduced. Any such reproduction shall be admissible in evidence as the
original itself in any judicial or administrative proceeding (whether or not the
original is in existence and whether or not such reproduction was made in the
regular course of business). Any facsimile which bears proof of transmission
shall be binding on the party which or on whose behalf such

                                       62


<PAGE>   63



transmission was initiated and likewise shall be so admissible in evidence as if
the original of such facsimile had been delivered to the party which or on whose
behalf such transmission was received.

         14-9.    MASSACHUSETTS LAW. This Agreement and all rights and
obligations hereunder, including matters of construction, validity, and
performance, shall be governed by the laws of The Commonwealth of Massachusetts
(except with respect to its conflicts of laws).

         14-10.   CONSENT TO JURISDICTION. (a) The Agent Borrower and each of
the Principal Borrowers agree that any legal action, proceeding, case, or
controversy against the Agent Borrower or any Principal Borrower with respect to
any Loan Document may be brought in the Superior Court of Suffolk County
Massachusetts or in the United States District Court, District of Massachusetts,
sitting in Boston, Massachusetts, as the Lender may elect in the Lender's sole
discretion. By execution and delivery of this Agreement, the Agent Borrower and
each Principal Borrower, for itself and in respect of its property, accepts,
submits, and consents generally and unconditionally, to the jurisdiction of the
aforesaid courts.

                  (b)      The Agent Borrower and each of the Principal
Borrowers WAIVES personal service of any and all process upon them, and
irrevocably consents to the service of process out of any of the aforementioned
courts in any such action or proceeding by the mailing of copies thereof by
certified mail, postage prepaid, to the Agent Borrower or any Principal Borrower
at the address for notices as specified herein, such service to become effective
five (5) Business Days after such mailing.

                  (c)      The Agent Borrower and each of the Principal
Borrowers WAIVES, at the option of Lender, any objection based on FORUM NON
CONVENIENS and any objection to venue of any action or proceeding instituted
under any of the Loan Documents and consents to the granting of such legal or
equitable remedy as is deemed appropriate by the Court.

                  (d)      Nothing herein shall affect the right of the Lender
to bring legal actions or proceedings in any other competent jurisdiction.

                  (e)      The Agent Borrower and each of the Principal
Borrowers agrees that any action commenced by the Agent Borrower and any
Principal Borrower asserting any claim or

                                       63


<PAGE>   64



counterclaim arising under or in connection with this Agreement or any other
Loan Document shall be brought in the Superior Court of Suffolk County
Massachusetts or in the United States District Court, District of Massachusetts,
sitting in Boston, Massachusetts, and that such Courts shall have exclusive
jurisdiction with respect to any such action.

         14-11.   INDEMNIFICATION. The Principal Borrowers hereby indemnify,
defend, and hold the Lender and any employee, officer, or agent of the Lender
(each, an "INDEMNIFIED PERSON") harmless of and from any claim brought or
threatened against any Indemnified Person by any Person (as well as from
attorneys' reasonable fees and expenses in connection therewith) on account of
the Lender's relationship with the Agent Borrower, any Principal Borrower or any
other guarantor or endorser of the Obligations (each of which may be defended,
compromised, settled, or pursued by the Indemnified Person with counsel of the
Lender's selection, but at the expense of each Principal Borrower) other than
any claim as to which a final determination is made in a judicial proceeding (in
which the Lender and any other Indemnified Person has had an opportunity to be
heard), which determination includes a specific finding that the Indemnified
Person seeking indemnification had (i) acted in a grossly negligent manner or
(ii) acted with willful misconduct or (iii) been due to Lender's breach
hereunder resulting from the Lender's gross negligence or willful misconduct.
The within indemnification shall survive payment of the Obligations and/or any
termination, release, or discharge executed by the Lender in favor of the Agent
Borrower and any Principal Borrower.

         14-12.   RULES OF CONSTRUCTION. (a) The following rules of construction
shall be applied in the interpretation, construction, and enforcement of this
Agreement and of the other Loan Documents:

                           (i)      Words in the singular include the plural and

         not constitute a part of the instrument in which included and do not
         affect such instrument's meaning, construction, or effect.

                           (iii)    The words "includes" and "including" are not
         limiting.

                           (viii)   References to "herein", "hereof", and
         "within" are to this entire Loan Agreement and not merely the provision
         in which such reference is included.

                           (ix)     Except as otherwise specifically provided,
         all references to time are to Boston time.

                           (x)      In the determination of any notice, grace,
         or other period of time prescribed or allowed hereunder, unless
         otherwise provided (A) the day of the act, event, or default from which
         the designated period of time begins to run shall not be included and
         the last day of the period so computed shall be included unless such
         last day is not a Business Day, in which event the last day of the
         relevant period shall be the then next Business Day and (B) the period
         so computed shall end at 5:00 PM on the relevant Business Day. (b) The

         Principal Borrowers.

                                       65


<PAGE>   66



                  (d)      The Lender's consent to any action of the Agent
         Borrower or any Principal Borrower which is prohibited unless such
         consent is given may be given or refused by the Lender in its sole
         discretion.

         14-14.   RIGHT OF SET-OFF. Following and during the continuance of an
Event of Default any and all deposits or other sums at any time credited by or
due to any Principal Borrower from the Lender and any cash, securities,
instruments or other property of the undersigned in the possession of the
Lender, whether for safekeeping or otherwise (regardless of the reason the
Lender or the Participant had received the same) shall at all times constitute
security for all Obligations and for any and all obligations of the undersigned
to the Lender, and may be applied or set off against the Obligations and against
the obligations of the undersigned to the Lender including, without limitation,
those arising hereunder, at any time while an Event of Default is then existing,
whether or not such are then due and whether or not other collateral is then
available to the Lender.

         14-15.   MAXIMUM INTEREST RATE. Regardless of any provision of any Loan
Document, the Lender shall never be entitled to contract for, charge, receive,
collect, or apply as interest on any Obligation, any amount in excess of the
maximum rate imposed by applicable law. Any payment which is made which, if
treated as interest on an Obligation would result in such interest's exceeding
such maximum rate shall be held, to the extent of such excess, as additional
collateral for the Obligations as if such excess were "Collateral."

         14-16.   FEDERAL RESERVE BANK PLEDGE. The Lender may at any time pledge
or assign all or any portion of the Lender's rights under this Agreement and the
other Loan Documents to a Federal Reserve Bank; provided, however, that no such
pledge or assignment shall release the Lender from the Lender's obligations
hereunder or under any other Loan Document.

         14-17.   WAIVERS. (a) The Agent Borrower and each of the Principal
Borrowers (and all guarantors, endorsers, and sureties of the Obligations) make
each of the waivers included in Subsection (b), below, knowingly, voluntarily,
and intentionally, and understands that the Lender,

                                       66


<PAGE>   67



in entering into the financial arrangements contemplated hereby and in providing
loans and other financial accommodations to or for the account of any and each
of the Principal Borrowers as provided herein, whether not or in the future, is
relying on such waivers.

                  (b)      THE AGENT BORROWER, THE PRINCIPAL BORROWERS, AND EACH
SUCH GUARANTOR, ENDORSER, AND SURETY RESPECTIVELY WAIVES THE FOLLOWING:

                           (i)      Except as otherwise specifically required
         hereby, notice of non-payment, demand, presentment, protest and all
         forms of demand and notice, both with respect to the Obligations and
         the Collateral (except as provided in any Loan Document).

                           (ii)     Except as otherwise specifically required by
         any Loan Document, the right to notice and/or hearing prior to the
         Lender's exercising of the Lender's rights upon default.

                           (iii)    THE RIGHT TO A JURY IN ANY TRIAL OF ANY CASE
         OR CONTROVERSY IN WHICH THE LENDER IS OR BECOMES A PARTY (WHETHER SUCH
         CASE OR CONTROVERSY IS INITIATED BY OR AGAINST THE LENDER OR IN WHICH
         THE LENDER IS JOINED AS A PARTY LITIGANT), WHICH CASE OR CONTROVERSY
         ARISES OUT OF OR IS IN RESPECT OF, ANY RELATIONSHIP AMONGST OR BETWEEN
         THE AGENT BORROWER, ANY PRINCIPAL BORROWER OR ANY OTHER PERSON AND THE
         LENDER (AND THE LENDER LIKEWISE WAIVES THE RIGHT TO A JURY IN ANY TRIAL
         OF ANY SUCH CASE OR CONTROVERSY).

                           (iv)     Any defense, counterclaim, set-off,
         recoupment, or other basis on which the amount of any Obligation, as
         stated on the books and records of the Lender, could be reduced or
         claimed to be paid otherwise than in accordance with the tenor of and
         written terms of such Obligation except this does not limit any right
         of any Principal Borrower or the Agent Borrower to obtain any
         affirmative recovery from Lender.

                           (v)      Any claim to consequential, special, or 
         punitive damages.

Boston, Massachusetts                                            April 30, 1998



         FOR VALUE RECEIVED, the undersigned, (individually and collectively,
jointly and severally, the "BORROWERS") promise to pay to the order of
BankBoston, N.A. a national banking association with offices at 100 Federal
Street, Boston, Massachusetts 02110 (with any subsequent holder, the "LENDER")
the aggregate unpaid principal balance of loans and advances made by the Lender
to the Borrowers pursuant to the Revolving Credit established pursuant to the
Agented Loan and Security Agreement of even date (as such may be amended
hereafter, the "LOAN AGREEMENT") between the Lender and the Borrowers, with
interest, at the rate and payable in the manner, stated therein.

         This is the "Master Note" to which reference is made in the Loan
Agreement, and is subject to all terms and provisions thereof. The principal of,
and interest on, this Note shall be payable as provided in the Loan Agreement
and shall be subject to acceleration as provided therein.

         The Lender's books and records concerning the Lender's loans and
advances pursuant to the Revolving Credit, the accrual of interest thereon, and
the repayment of such loans and advances, shall be prima facie evidence of the
indebtedness to the Lender hereunder.

         No delay or omission by the Lender in exercising or enforcing any of
the Lender's powers, rights, privileges, remedies, or discretions hereunder
shall operate as a waiver thereof on that occasion nor on any other occasion. No
waiver of any default hereunder shall operate as a waiver of any other default
hereunder, nor as a continuing waiver.

         Each of the Borrowers, and each endorser and guarantor of this Note,
respectively waives presentment, demand, notice, and protest, and also waives
any delay on the part of the holder hereof except as provided in the Loan
Agreement or any guaranty. Each assents to any extension or other indulgence
(including, without limitation, the release or substitution of collateral)
permitted by the Lender with respect to this Note and/or any collateral given to
secure this Note or any extension or other indulgence with respect to any other
liability or any collateral given to secure any other liability of any of the
Borrowers or any other person

                                        1

obligated on account of this note.

         This Note shall be binding upon each of the Borrowers, and each
endorser and guarantor hereof, and upon their respective heirs, successors,
assigns, and representatives, and shall inure to the benefit of the Lender and
its successors, endorsees, and assigns.

         The liabilities of the Borrowers, and of any endorser or guarantor of
this Note, are joint and several; provided, however, the release by the Lender
of or any one or more such person, endorser or guarantor shall not release any
other person obligated on account of this Note. Each reference in this Note to
the Borrowers, any endorser, and any guarantor, is to such person individually
and also to all such persons jointly. No person obligated on account of this
Note may seek contribution from any other person also obligated unless and until
all liabilities, obligations and indebtedness to the Lender of the person from
whom contribution is sought have been satisfied in full.

         Each of the Borrowers and each endorser and guarantor hereof each
authorizes the Lender to complete this Note if delivered incomplete in any
respect.

         This Note shall be governed by the laws of The Commonwealth of
Massachusetts and shall take effect as a sealed instrument.
