Item 1. Business

GENERAL

     CardioTech International, Inc. ("CardioTech" or the "Company") is using its
proprietary manufacturing technology to develop and manufacture small bore
vascular grafts, or synthetic blood vessels, made of ChronoFlex, a family of
polyurethanes that has been demonstrated to be biocompatible and non-toxic.
Vascular grafts are used to replace, bypass or provide a new lining or arterial
wall for occluded, damaged, dilated or severely diseased arteries and are used
to provide access for patients undergoing hemodialysis treatments.  The Company
is developing three types of layered, microporous small bore vascular grafts:
(i) a vascular access graft, called the VascuLink Access Graft; (ii) a
peripheral graft, called the MyoLink Peripheral Graft, and (iii) a coronary
artery bypass graft, called the CardioPass Coronary Artery Bypass Graft.

     Blood is pumped from the heart throughout the body via arteries.  Blood is
returned to the heart at relatively low pressure via veins, which have thinner
walls than arteries and have check valves which force blood to move in one
direction.  Because a specific area of the body is often supplied by a single
main artery, rupture, severe narrowing or occlusion of the artery supplying
blood to that area is likely to cause an undesirable or catastrophic medical
outcome.

     Vascular grafts are used to replace or bypass occluded, damaged, dilated or
severely diseased arteries and are sometimes used to provide access to the
bloodstream for patients undergoing hemodialysis treatments.  Existing small
bore graft technologies suffer from a variety of disadvantages in the treatment
of certain medical conditions, depending upon the need for biodurability,
compliance (elasticity) and other characteristics necessary for long-term
interface with the human body.

     CardioTech is developing its grafts using specialized ChronoFlex
polyurethane materials that it believes will provide significantly improved
performance in the treatment of arterial disorders. The grafts have three
layers similar to natural arteries and are designed to replicate the physical
characteristics of human blood vessels.

     Additionally, through its CT Biomaterials division, the Company develops,
manufactures and markets polyurethane-based biomaterials for use in both acute
and chronically implanted devices such as stents, artificial hearts, and
vascular ports.  These premium biomaterials are sold under the tradenames:
ChronoFlex, ChronoThane, HydroThane and ChronoFilm.

     CardioTech owns a number of patents relating to its vascular graft
manufacturing technology.  In addition, PolyMedica Corporation ("PMI") has
granted to CardioTech an exclusive, perpetual, worldwide, royalty-free license
for the use of one polyurethane patent and related technology in the field
consisting of the development, manufacture and sale of implantable medical
devices and biodurable polymer material to third parties for the use in 

                                       2
<PAGE>
 
medical applications (the "Implantable Device and Materials Field"). PMI also
owns, jointly with Thermedics, Inc., the ChronoFlex polyurethane patents. PMI
has granted to CardioTech a non-exclusive, perpetual, worldwide, royalty-free
sublicense of these patents for use in the Implantable Devices and Materials
Field.

     The Company was founded in 1993 as a subsidiary of PMI. In June 1996, PMI
distributed (the "Spin Off") all of the shares of CardioTech's common stock, par
value $.01 per share (the "Common Stock"), that PMI owned to PMI stockholders of
record as of June 3, 1996. The Company is headquartered in Woburn, Massachusetts
and also has production facilities in Tarvin, U.K.

     ChronoFlex and ChronoFilm are registered trademarks of PMI. ChronoThane,
ChronoPrene, HydroThane, PolyBlend and PolyWeld are tradenames of CardioTech.
DuraGraft, VascuLink, MyoLink, CardioPass are trademarks of CardioTech.

PRODUCTS IN DEVELOPMENT
VASCULINK VASCULAR ACCESS GRAFT
     Patients suffering from end-stage renal disease may be required to undergo
hemodialysis.  The majority of these patients require long-term vascular access
to facilitate treatment.  A point of access for dialysis needles may be created
by connecting an artery and a vein in the patient's arm.  However, because
kidney dialysis therapy typically requires patients to undergo hemodialysis
treatment three times per week, these natural shunts often become unusable over
time.  Other methods of vascular access for kidney dialysis, such as
transcutaneous catheters, are only designed for temporary use.

     A synthetic graft is implanted in hemodialysis patients to provide routine
vascular access.  The vast majority of these synthetic grafts are presently made
of polytetafluoroethylene ("ePTFE").  The use of ePTFE grafts is often
accompanied by excessive bleeding when the dialysis needle is withdrawn,
requiring a nurse to apply pressure to help stop the bleeding and requiring the
patient to remain in the treatment area until the bleeding has stopped.  In
addition, to limit the risk of graft infection following implant, at least a
four to six week healing period following implantation is required before
initiating dialysis in order to allow for tissue in-growth into the graft.

     The Company believes that the VascuLink Graft that it is developing may
offer advantages over currently used synthetic grafts because of its needle-
hole-sealing-capability.  The Company believes that this characteristic will be
effective in sealing puncture sites in its grafts with minimal compression time
and bleeding as compared with ePTFE grafts and, as a result, will reduce
dialysis procedure and administrative time per patient and their associated
costs.  In addition, the Company believes, based on animal studies, that
patients who receive the VascuLink Graft will be able to be dialized in a
shorter period of time than four to six weeks.

     The Company believes that approximately 185,000 patients in the United
States undergo kidney dialysis each year, of which approximately 140,000 undergo
vascular access surgeries using either natural vessel grafts or synthetic access
grafts.  The Company estimates that of these patients, approximately 55,000 are
implanted with synthetic grafts.  The Company believes that a comparable market
exists overseas.

                                       3
<PAGE>
 
     The Company is currently conducting Phase I clinical trials of the
VascuLink Graft in Holland, France and Sweden with patients undergoing routine
hemodialysis treatment. The Company's clinical trials will compare patency and
complication rates of the Company's VascuLink Graft with ePTFE grafts. The
clinical trial in Holland, which began in November 1996, involves one site and
up to 20 patients. The clinical trial in France, which began in June 1997,
involves three sites and up to 40 patients. The clinical trial in Sweden, which
began in the last quarter of Fiscal 1998 involves two sites. There can be no
assurance that the Company's clinical trials will be successful.

MYOLINK PERIPHERAL GRAFT

     In the United States, an estimated 16 million people suffer from diabetes,
which is often further complicated by atherosclerosis, or the blockage of
arteries.  Eventually, many atherosclerosis patients require vascular grafts to
bypass severely occluded leg arteries, which impede circulation to the lower
extremities and can ultimately lead to amputation.  Lack of adequate circulation
to the lower limbs and toes results in approximately 54,000 yearly amputations
in the United States alone.  Current techniques of surgical intervention rely on
autologous saphenous veins from the leg for use as substitute vessels.

     However in over 40% of all atherosclerosis patients, the saphenous veins
are deemed unsuitable, making it necessary to use a vein constructed from
artificial materials.  The Company is designing the MyoLink Peripheral Graft
that it is developing to be suitable for providing needed circulation from the
upper thigh, across the knee and into the mid calf.  In order to accommodate the
bend at the knee, CardioTech has designed the MyoLink graft to be "non-kinking."
Further, CardioTech believes that it has the expertise and capability to
manufacture a graft that tapers from an inside diameter of approximately 6mm for
the portion above the knee to an inside diameter of approximately 4mm for the
portion below the knee, roughly the same dimensions as the natural artery.  The
Company is currently conducting pre-clinical development studies of the MyoLink
Graft at its Tarvin, UK facility.

     On April 1, 1998, the Company, through its wholly owned subsidiary,
CardioTech International, Ltd. ("CTI Ltd."), entered into a two year research
collaboration with The Royal Free Hospital School of Medicine (University of
London) ("Royal"), which relates to the investigation and clinical trials of the
MyoLink graft and the clinical evaluation of endothelial cell-seeding of
peripheral vascular grafts. This research, if successfully commercialized may
result in the payment of royalties to the Royal Free Hospital. The research will
be funded by a loan of /(pounds)/252,942 ($414,765) (the "Loan") from Freemedic
PLC, a subsidiary of Royal (together with Royal, "Freemedic"), to CTI Ltd. The
Loan, plus accrued interest, is convertible under certain conditions, at either
the Company's or Fremedic's option, into Common Stock of the Company at a
conversion price of $3.70 per share. Freemedic may terminate the collaboration
at any time upon a material breach by the Company of any obligation under the
collaboration agreement or upon an event of default under the Loan agreement.

CARDIOPASS CORONARY ARTERY BYPASS GRAFT

     Coronary artery bypass graft ("CABG") surgery is performed to treat the
impairment of blood flow to portions of the heart.  CABG surgery involves the
addition of one or more new vessels to the heart to re-route blood around
blocked coronary arteries.

     Autogenous grafts (using the patient's own saphenous vein or mammary
artery) have been successfully used in CABG procedures for a number of years and
have shown a relatively high patency rate (80% to 90% for saphenous veins and
over 90% for mammary arteries one year after surgery) with no risk of tissue
rejection.  However, the surgical harvesting of vessels for autogenous grafts
involves significant trauma and expense.  In addition, not all patients
requiring CABG surgery have sufficient native vessels as a result of previous
bypass surgeries, or their vessels may be of inferior quality due to trauma or
disease.  Cryopreserved saphenous veins are available, but these veins often
deteriorate due to attack by the body's immune system.

                                       4
<PAGE>
 
     The Company is developing the CardioPass Coronary Artery Bypass Graft to be
a synthetic graft of 3mm in diameter specifically designed for use in CABG
surgery.  If successfully developed, the Company believes that the CardioPass
Graft may be used initially to provide an alternative to patients with
insufficient or inadequate native vessels for use in bypass surgery as a result
of repeat procedures, trauma, disease or other factors.  The Company believes,
however, that the CardioPass Graft may ultimately be used as a substitute for
native saphenous veins, thus avoiding the trauma and expense associated with the
surgical harvesting of the vein.

     The Company believes that in 1995, approximately 700,000 CABG procedures
were performed worldwide, of  which nearly 500,000 were performed in the United
States.  The Company believes that approximately 20% of these CABG procedures
were performed on patients who had previously undergone bypass surgery, and that
the number of repeat procedures will continue to increase as a percentage of
procedures performed.  Currently, approximately 70% of CABG procedures are
performed utilizing the saphenous vein.

     The Company estimates that approximately 100,000 patients are diagnosed by
their physicians as having native vessels that are inadequate for use in bypass
surgery.  The CardioPass Coronary Artery Bypass Graft is currently in pre-
clinical development.  If the CardioPass Graft is successfully developed, the
Company believes that the graft may initially be used for these patients.  The
Company also believes that if long-term clinical results are acceptable to
clinicians (generally, greater than 50% patency five years after implant), the
graft may ultimately be used as a direct substitute for autogenous saphenous
veins.

BIOMATERIALS

     CardioTech also develops, manufactures and sells a range of polymer-based
materials customized for use in the manufacture of certain medical devices to
other medical device manufacturers.  CardioTech sells these custom polymers
under the tradenames ChronoFilm, ChronoFlex, ChronoThane, ChronoPrene,
HydroThane, PolyBlend and PolyWeld.  The Company also provides development
services relating to biomaterials to medical device customers.  In 1992, PMI
entered into a long term development and materials supply agreement with Bard
Access Systems, Inc. pursuant to which Bard purchases ChronoFlex for use in the
manufacture of a line of catheters and implantable vascular access ports that
are used to deliver doses of pharmaceuticals over an extended period of time or
to deliver chemotherapy agents to specific organs.  PMI assigned this agreement
to CardioTech prior to the Spin Off.

     CardioTech also manufactures and sells its proprietary HydroThane
biomaterials to medical device manufacturers that are evaluating HydroThane for
use in their products.  HydroThane is a thermoplastic, water-absorbing,
polyurethane elastomer, that posses properties that CardioTech believes make it
well suited for the complex requirements of a variety of catheters.  In addition
to its physical properties, CardioTech believes HydroThane exhibits an inherent
degree of bacterial resistance, clot resistance and biocompatibility.  When
hydrated, HydroThane has elastic properties similar to living tissue.

     During the fiscal year ended March 31, 1998, the Company was the recipient
of two Small Business Innovation Research grants awarded by National Institutes
of Health ("NIH") to support the Company's research and development programs.

                                       5
<PAGE>
 
     Research revenues related to biomaterials were approximately $872,521 and
$570,676 for the year ended March 31, 1998 and 1997, respectively.  For the year
ended March 31, 1998, 26% and 56% of research revenues were generated from Bard
Access Systems, Inc. and the NIH, respectively.

MANUFACTURING

     CardioTech currently manufactures limited quantities of ChronoFlex and
HydroThane for sale to medical device manufacturers.  To date, CardioTech's
manufacturing activities with respect to the specialized ChronoFlex materials
used in vascular grafts have consisted primarily of manufacturing small
quantities of such products for use in clinical trials.  CardioTech currently
has the ability to produce quantities of vascular grafts sufficient to support
its current testing needs.  CardioTech also has the ability to produce
quantities of vascular grafts sufficient to support its needs for early-stage
clinical trials.  However, CardioTech may need to acquire manufacturing
facilities and improve its manufacturing technology in order to meet the volume
and cost requirements for later clinical trials and will require additional
manufacturing facilities in order to undertake commercial production of vascular
grafts, if it elects to do so.  To achieve profitability, CardioTech's products
must be manufactured in commercial quantities in compliance with regulatory
requirements and at acceptable costs.  Production in commercial quantities will
require CardioTech to expand its manufacturing capabilities significantly and to
hire and train additional personnel.  CardioTech has no experience in large-
scale manufacturing, and there can be no assurance that CardioTech will be able
to make the transition to commercial production successfully.

     The Company's manufacturing operations in the United Kingdom currently hold
an ISO 9001 Certificate of Registration from National Quality Assurance, Ltd. 
This internationally recognized endorsement of ongoing quality management 
represents the highest level of certification available.


     The development and manufacture of CardioTech's products are subject to
good laboratory practice ("GLP") and good manufacturing practice ("GMP")
requirements prescribed by the Food and Drug Administration ("FDA") and other
standards prescribed by the appropriate regulatory agency in the country of use.
There can be no assurance that CardioTech will be able to obtain or manufacture
products in a timely fashion at acceptable quality and prices, that it or any
suppliers can comply with GLP or GMP, as applicable, or that it or such
suppliers will be able to manufacture an adequate supply of product.

MARKETING

     CardioTech plans to market its vascular graft products for which it obtains
regulatory approvals either through a small targeted direct sales group or
through licensing arrangements with large medical device companies.
Implementation of this strategy will depend on many factors, including the
market potential for CardioTech's products and financial resources.  There can
be no assurance that CardioTech will be able to successfully market its
products.

COMPETITION

     Competition in the medical device industry in general is intense and based
primarily on scientific and technological factors, the availability of patent
and other protection for technology and products, the ability to commercialize
technological developments and the ability to obtain governmental approval for
testing, manufacturing and marketing products.

                                       6



<PAGE>
 
     CardioTech will compete with products offered by W.L. Gore and Associates
("W.L. Gore"), Impra, Inc. ("Impra"), Corvita Corporation ("Corvita") and
Thoratec Corporation ("Thoratec").  CardioTech believes that W.L. Gore and
Impra, whose synthetic graft products have been sold in the United States and
worldwide for many years, sell approximately 90% of the intermediate diameter
peripheral synthetic vascular grafts and vascular access grafts used throughout
the world.  While CardioTech believes that the attributes of its vascular grafts
will allow it to compete effectively, both W.L. Gore and Impra can be expected
to defend their market positions vigorously, and both have substantially greater
financial, technical and other resources than CardioTech.  Corvita is developing
a broad range of polyurethane based synthetic vascular grafts, including
vascular access grafts and has commenced clinical trials of certain of its
synthetic vascular graft products in both the United States and Europe.
Thoratec has developed a small bore polyurethane vascular access graft and has
begun limited clinical trials in foreign countries.  The joint technology may be
licensed or otherwise made available to competitors of CardioTech.

     Competition among these products will be based, among other things, on
product efficacy, safety, reliability, availability, price and patent position.
An important factor will be the timing of the market introduction of
CardioTech's or competitive products.  Accordingly, the relative speed with
which CardioTech can develop products, complete the clinical trials and approval
processes and supply commercial quantities of the products to the market is
expected to be an important competitive factor.  CardioTech's competitive
position will also depend upon its availability to attract and retain qualified
personnel, to obtain patent protection or otherwise develop proprietary products
or processes, and to secure sufficient capital resources for the often
substantial period between technological conception and commercial sales.

RESEARCH AND DEVELOPMENT

     CardioTech's research and development efforts are focused on developing its
synthetic vascular graft technologies.  CardioTech's development decisions are
based on (1) development costs, (2) product need, (3) third-party interest and
funding availability and (4) regulatory considerations.  CardioTech believes it
will need substantial additional financing to conduct human clinical trials, and
produce vascular access graft and other planned products.  No assurance can be
given, however, that such financing, or other financing, will be available on
terms attractive to CardioTech, if at all. Research and Development expenditures
for the years ended March 31, 1998, 1997 and 1996 were $1,638,381, $1,031,605 
and $910,676 respectively.

GOVERNMENT REGULATION

     CardioTech's research and development activities are subject to regulation
for safety, efficacy and quality by numerous governmental authorities in the
United States and other countries.  In the United States, the development,
manufacturing and marketing of synthetic vascular grafts are subject to
regulation for safety and efficacy by the FDA in accordance with the Food, Drug
and Cosmetic Act.  Synthetic vascular grafts are subject to rigorous FDA
regulation, including pre-clinical and clinical testing.  The process of
completing clinical trials and obtaining FDA approvals for a medical device is
likely to take a number of years, requires the expenditure of substantial
resources and is often subject to unanticipated delays.  There can be no
assurance that any product will receive such approval on a timely basis, if at
all.

                                       7
<PAGE>
 
     The steps required to qualify a medical device for marketing in the United
States are complex.  Medical products regulated by the FDA are generally
classified as drugs and/or medical devices.  Medical devices are classified as
Class I, II or III devices.  CardioTech believes that its synthetic vascular
grafts will be regulated as Class III medical devices.  In general, Class I
devices require compliance with labeling and record keeping regulations and are
subject to other general controls.  Class II devices may be subject to special
controls, such as market surveillance and are subject to general controls.
Class II devices also may not be subject to clinical testing for purposes of
pre-market notification to the FDA.  Class III devices, such as CardioTech's
vascular graft products, require clinical testing to assure safety and
effectiveness prior to marketing and distribution.

     At least 90 days prior to marketing, devices must be subject to pre-market
notification to the FDA to determine the product's classification and regulatory
status. If a product is found to be "substantially equivalent" to a Class I or
Class II device, or a Class III device not subject to a Pre-Marketing
Application (PMA) requirement, it may be marketed without further FDA review.
The FDA may require the submission of clinical data as a basis for determining
whether a device is "substantially equivalent." Such clinical data is often
developed under an Investigational Drug Exemption (IDE). Marketing may commence
only when the FDA issues a written order finding that the device is
"substantially equivalent." If a device is found to be "not substantially
equivalent," the device manufacturer must file a PMA with the FDA based on
testing intended to demonstrate that the product is both safe and effective.
CardioTech believes that its products will require the issuance of a PMA from
the FDA prior to commercial sale.

     The PMA process requires the performance of human clinical studies under an
IDE.  Upon completion of required clinical studies, results are presented to the
FDA in a PMA application.  In addition to the results of clinical
investigations, the PMA applicant must submit other information relevant to the
safety and effectiveness of the device, including the results of pre-clinical
tests; a full description of the device and its components; a full description
of the methods, facilities and controls used for manufacturing; and proposed
labeling.  The FDA staff then determines whether to accept the application for
filing.  If accepted for filing, the application is further reviewed by the FDA
and then usually reviewed by an FDA scientific advisory panel of physicians and
others with expertise in the relevant field.  The FDA will also conduct an
inspection to determine whether an applicant conforms with the FDA's current
GMP.  If the FDA's evaluation is favorable, the FDA will subsequently publish an
order granting the PMA for the device.  Although the initial PMA review process
is required to be completed within 180 days from the date that the PMA
application is accepted for filing, the FDA routinely raises additional issues
which must be addressed prior to the approval of a PMA, which significantly
extends the review process.

     There can be no assurance that the FDA will approve any of CardioTech's
products currently under research for marketing, or if they are approved, that
they will be approved on a timely basis.  Furthermore, CardioTech or the FDA may
suspend clinical trials at any time upon a determination that the subjects or
patients are being exposed to an unacceptable adverse health risk ascribable to
CardioTech's products.  If clinical studies are suspended, CardioTech may be
unable to continue the development of the investigational products affected.

                                       8
<PAGE>
 
     Whether or not FDA approval has been obtained, approval of a medical device
by comparable foreign governmental regulatory authorities must be obtained prior
to the commencement of clinical trials and subsequent marketing of such products
in such countries.  Under European Community ("EC") Law, the safety, efficacy
and quality of CardioTech's products must be demonstrated prior to marketing,
including extrinsic clinical testing of such products.  National laws in each of
the EC member states govern clinical trials of products, adherence to good
manufacturing practice, advertising, promotion and other matters.  Certain EC
member countries permit the sale of medical devices based upon approvals
received in other EC member states.  There can be no assurance that approvals
will be granted on a timely basis and the failure to receive such approvals
could have a material adverse effect on the business, financial condition and
results of operation of CardioTech.

EXCHANGE LISTING

     The Company's outstanding stock is currently listed on the American Stock
Exchange under the ticker symbol "CTE." CardioTech was granted listing approval
for 1,066,792 shares of its common stock for the 1998 calendar year. However,
there can be no assurance that these shares will not be de-listed during the
1998 calendar year. If the Company's shares were to be de-listed, it is likely
that CardioTech's fund raising ability would be adversely affected.

EMPLOYEES

     As of June 1998, the Company has 10 full-time employees. Of these full-time
employees, 4 are in research and development, 2 are in manufacturing and
production, and 4 are in management, administrative, or marketing positions.
None of the Company's employees is covered by a collective bargaining agreement,
and management considers its relations with its employees to be good.

YEAR 2000 ISSUES

     The Company uses computer software programs for its financial business
systems and administrative functions. The Company believes that its programs are
"Year 2000" compliant, and will be able to appropriately interpret the upcoming
calendar year "2000." However, there can be no assurance that potential "Year
2000" compliance failures will not have a material adverse affect on the
Company's business, results of operations or financial condition.

ITEM 2.  PROPERTIES

     CardioTech leases a total of approximately 9,300 square feet at PMI's
facilities in Woburn, Massachusetts and Tarvin, United Kingdom.  CardioTech
believes that its current facilities are adequate for the next 3 months, after
which the lease relating to these facilities will expire and CardioTech will
need to seek replacement facilities.  Although CardioTech believes that
alternative facilities can be leased on acceptable terms, there is no assurance
that CardioTech will be able to do so.

ITEM 3.  LEGAL PROCEEDINGS

     The Company is not a party to any 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.

     As of June 29, 1998, there were approximately 476 stockholders of record
and 2,970 additional beneficial stockholders (stockholders holding Common
Stock in brokerage accounts). The Company has never paid a cash dividend on its
Common Stock and does not anticipate the payment of cash dividends in the
foreseeable future.

Item 7.  Management's Discussion and Analysis of Financial Condition and
          Results of Operations

REVENUE

     Research revenue consists of revenues from the sale of medical grade
polyurethanes, research grants from the NIH and royalties from Bard Access
Systems. Research revenue increased $301,845, or 53%, to $872,521 for the fiscal
year ended March 31, 1998. Research revenues for the fiscal year ended March 31,
1997 increased  $341,870, or 149%, to $570,676 from $228,806 for the 1996 fiscal
year. The increases in both periods were primarily due to an increase in revenue
derived from NIH grants, an increase in royalty revenues, and an increase in the
company's sale of medical grade polyurethanes.

OPERATING EXPENSES

RESEARCH AND DEVELOPMENT
     Research and development expenses consist principally of employment-related
costs for scientific staff, facility costs, pre-clinical and clinical testing
costs, costs related to on-going development efforts and NIH grant expenses.  To
date, all of the Company's research and development expenses have been charged
to operations as incurred. Research and development expenses increased $606,776,
or 59%, to $1,638,381 in the 1998 fiscal year and $120,929, or 13%, to
$1,031,605 in the 1997 fiscal year. The increases in both periods were primarily
the result of expenditures related to clinical trials of the VascuLink Vascular
Access Grafts in Europe and the NIH grants. Approximately 50% of the Company's
expenditures relating to these NIH grants are contracted to outside hospitals
and laboratories. The Company intends to increase its clinical trials sites for
the Vasculink Vascular Access graft as well as beginning clinical trials on
Myolink Peripheral Graft, and, therefore, anticipates that the cost of research
and development will continue to increases in the 1999 fiscal year.

SELLING, GENERAL AND ADMINISTRATIVE
     Selling, general and administrative expenses consist principally of
employment-related cost for executive, selling and administrative personnel,
professional fees, consulting fees, system support costs, and other general and
administrative expenses.  Selling, general, and administrative expenses
increased $215,217, or 24%, to $1,118,233 in the 1998 fiscal year and $390,090,
or 76%, to $903,016 in the 1997 fiscal year.  The increase in the selling,
general, and administrative expenses in the 1998 fiscal year was principally due
to increased costs as the Company continued to establish itself as a stand-alone
company and incurred costs related to professional, legal, and consulting fees,
as well as marketing and selling, investor relations and public reporting
expenses. The increase in selling, general and administrative expenses in the
1997 fiscal year was principally due to additional costs incurred by the Company
subsequent to the Spin-off, including expenses related to the establishment of a
separate finance and accounting group, investor relations, and public reporting
fees, rent, insurance and legal representation. The Company anticipates that
selling, general, and administrative expenses will increase in the 1999 fiscal
year due to growth in management systems and marketing and selling efforts.

                                       13
<PAGE>
 
OTHER INCOME AND EXPENSES
     Other income and expenses is comprised of interest income related to the
Company's invested cash balances, offset by costs associated with the spin off.
The Company generally invests its cash in money market accounts. The amount of
interest income fluctuates based on the amount of funds available and the
prevailing interest rates. Other income and expenses improved $366,765, to
income of $75,138 for the 1998 fiscal year. During the 1997 fiscal year, other
income and expenses decreased $701,607, or 71%, to an expense of $291,627. The
1997 expense balance included $393,879 in spin-off transaction costs offset by
interest income of $102,897. The decrease in interest income for the year ended
March 31, 1998 was primarily due to reduced money market balances due to
operational cash flow needs.

PROVISION FOR INCOME TAXES

     The Company had no provision for income taxes for the 1996, 1997, and 1998
fiscal years due to the fact that it incurred net operating losses for these
fiscal years.  The Company has an operating loss carried forward for the period
June 12, 1996 to March 31, 1998 of approximately $3,678,000.  Losses for the
periods prior to June 12, 1996 were consolidated with the results of PMI and,
accordingly, CardioTech will not receive any benefit from net operating losses
prior to June 12, 1996.

LIQUIDITY AND CAPITAL RESOURCES

     CardioTech's future growth will depend on its ability to raise capital to
support research and development activities and to commercialize its vascular
graft technology. To date, CardioTech has not generated revenues from the sale
of vascular grafts, although it has received research revenues relating to its
other biomaterial sales and from the NIH to support graft research. Since
inception, funding has come from PMI and 7% Senior convertible notes with a face
value of $1,660,000 issued on March 31, 1998. CardioTech expects to continue to
incur operating losses unless and until product sales and/or royalty generate
sufficient revenues to fund its continuing operations.

     CardioTech will require substantial funds for further research and
development, future pre-clinical and clinical trials, regulatory approvals,
establishment of commercial-scale manufacturing capabilities, and the marketing
of its products.  CardioTech's capital requirements depend on numerous factors,
including but not limited to, the progress of its research and development
programs, the progress of pre-clinical and clinical testing, the time and costs
involved in obtaining regulatory approvals, the cost of filing, prosecuting,
defending and enforcing any intellectual property rights, competing
technological and market developments, changes in CardioTech's development of
commercialization activities and arrangements, and the purchase of additional
facilities and capital equipment.

     CardioTech is currently conducting its operations with approximately
$2,226,691 in cash.  CardioTech estimates such amount will be sufficient to fund
its working capital and research and development activities through June 1999.
However, CardioTech's spending level may increase depending on the Company's
ability to raise additional capital.

                                       14
<PAGE>
 
     Past spending levels are not necessarily indicative of future spending
levels. From the inception of CardioTech's business through March 31, 1996, PMI
funded approximately $4.0 million in operating losses to support CardioTech's
research activities. Future expenditures for product development, especially
related to outside testing and clinical trials, are discretionary and,
accordingly, can be adjusted as required depending on the amount of available
cash.

     CardioTech will seek to obtain additional funds through public or private
equity or debt financing, collaborative arrangements, or from other sources.
There can be no assurance that additional financing will be available at all or
on acceptable terms to permit successful commercialization of CardioTech's
technology and products. If adequate funds are not available, CardioTech may be
required to curtail significantly one or more if its research and development
programs, or obtain funds through arrangements with collaborative partners or
others that may require CardioTech to relinquish rights to certain of its
technologies, product candidates or products.

     The Company believes that this Form 10-K contains forward-looking
statements that are subject to certain risks and uncertainties. These forward-
looking statements include statements regarding the sufficiency of the Company's
liquidity and capital. Such statements are based on management's current
expectations and are subject to a number of factors and uncertainties that could
cause actual results to differ materially from the forward-looking statements.
The Company cautions investors that there can be no assurance that actual
results or business conditions will not differ materially from those projected
or suggested in such forward-looking statements as a result of various factors,
including but not limited to the following: the Company's ability to
successfully complete clinical trials in a timely manner, the Company's ability
to obtain financing to support its working capital needs, the timely development
of products by the Company, intense competition related to the development of
synthetic grafts and difficulties inherent in developing synthetic grafts. As a
result, the Company's further development involves an high degree of risks. For
further information, refer to the more specific risks and uncertainties
discussed throughout this report.

Year 2000 Compliance

     The Year 2000 Issue refers to potential problems with computer systems or 
any equipment with computer chips or software that use dates where the date has 
been stored as just two digits (e.g., 97 for 1997). On January 1, 2000, any 
clock or date recording mechanism incorporating the date sensitive software 
which uses only two digits to represent the year may recognize a date using 00 
as the year 1900 rather than the year 2000. This could result in a system 
failure or miscalculations causing disruption of operations, including, among 
other things, a temporary inability to process transactions, send invoices, or 
engage in similar business activities.

     The Company has conducted a review of its internal information systems to 
determine the extent of any Year 2000 problem. Based on such review, the Company
does not currently believe that it has material exposure to the Year 2000 Issue 
with respect to its own information systems, since its core existing business 
information systems correctly define the year 2000.

     The Company is in the process of contacting its major customers in a effort
to determine the extent to which the Company may be vulnerable to those parties'
failure to timely correct their own Year 2000 problems. To date, the Company is 
unaware of any situations of noncompliance that would materially adversely 
affect its operations or financial condition. There can be no assurance, 
however, that instances of noncompliance which could have a material adverse 
effect on the Company's operations or financial condition will not be 
identified; that the systems of other companies with which the Company transacts
business will be corrected on a timely basis; or that a failure by such entities
to correct a Year 2000 problem or a correction which is incompatible with the 
Company's information systems would not have a material adverse effect on the 
Company's operations or financial condition.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders of CardioTech International, Inc.:

     We have audited the accompanying consolidated balance sheets of CardioTech
International, Inc. as of March 31, 1998 and 1997, and the related consolidated
statements of operations, stockholders' 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, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of CardioTech
International, Inc. as of March 31, 1998 and 1997, and results of its operations
and its cash flows for the three years in the period ended March 31, 1998 in
conformity with generally accepted accounting principles.

     From inception to June 12, 1996 the Company was a majority-owned subsidiary
of PolyMedica Corporation. As explained in Note B to the financial statements,
for the period prior to June 12, 1996, certain of the costs and expenses in the
financial statements represent inter-company allocations and management
estimates of the costs of services provided by PolyMedica Corporation.  As a
result, the financial statements presented may not be indicative of the
financial position or results of operations that would have been achieved had
the Company operated as a non-affiliated entity.

                 CARDIOTECH INTERNATIONAL, INC. AND SUBSIDIARY
                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS


A.   NATURE OF BUSINESS:

     CardioTech International, Inc. (including its subsidiary, collectively
"CardioTech" or the "Company") is using its proprietary technology to develop
and manufacture small bore vascular grafts, or synthetic blood vessels, made of
ChronoFlex, a family of polyurethanes that have been demonstrated to be
biocompatible and non-toxic. The Company is headquartered in Massachusetts and
operates from manufacturing and laboratory facilities located in Massachusetts
and the United Kingdom.

B.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BASIS OF PRESENTATION

     CardioTech's business, which is the basis for these financial statements,
was a spin-off of a portion of the business of PolyMedica Corporation. ("PMI").
CardioTech was incorporated in March 1993. The accompanying financial statements
for the year 1996 and the period April 1, 1996 through June 11, 1996 were
derived from the historical books and records of PMI and include the assets,
liabilities, revenues and expenses of CardioTech at historical cost.

     CardioTech's spun-off business operated as a division of PMI starting in
1990. In September 1993, PMI purchased certain assets of Newtec Vascular
Products Limited ("Newtec"), a company that had conducted development work on
small bore vascular grafts. Newtec operated as a division of PMI until June
1995, when it was incorporated as a wholly-owned subsidiary of CardioTech.

     The financial statements for the periods prior to June 12, 1996 are
intended to present management's estimates of the results of consolidated
operations and financial condition of CardioTech as if it had operated as a
stand-alone company since inception. Certain of the costs and expenses for the
periods prior to June 12, 1996 presented in these consolidated financial
statements represent inter-company allocations and management estimates of the
cost of services provided by PMI and its subsidiaries.

     In June 1996, the Company issued 1,412,625 shares of Common Stock, par
value of $.01 per share (the "Common Stock"), to PMI for $3.8 million in cash,
equipment having an estimated market value of $147,000, the transfer of certain
vascular graft manufacturing patents, and the forgiveness of certain amounts due
to PMI. After it acquired these shares, PMI owned 3,929,493 shares, or 92.6%, of
the Common Stock. On June 12, 1996 and June 19, 1996, PMI distributed (the "Spin
Off") all of the shares of Common Stock that it owned to its stockholders of
record as of June 3, 1996. On June 11, 1996, all advances from PMI to CardioTech
were converted to equity and are now classified by the Company as additional
paid in capital.

                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                  (continued)


BASIS OF CONSOLIDATION

     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary.  All significant inter-company balances and
transactions have been eliminated.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results may differ from those estimates and such
differences may be material to the financial statements.

FUTURE OPERATIONS

     CardioTech's future growth will largely depend on its ability to raise
additional capital to support research and development activities and to
commercialize its vascular graft technology. CardioTech expects to continue to
incur operating losses until vascular graft product sales and/or royalty
payments generate sufficient revenue to fund its continuing operations.

     CardioTech will require substantial funds for further research and
development, future pre-clinical and clinical trials, regulatory approvals,
establishment of commercial-scale manufacturing capabilities, and the marketing
of its products. CardioTech's capital requirements depend on numerous factors,
including but not limited to the progress of its research and development
programs, the progress of pre-clinical and clinical testing, the time and costs
involved in obtaining regulatory approvals, the cost of filing, prosecuting,
defending and enforcing any intellectual property rights, competing
technological and market developments, changes in CardioTech's development of
commercialization activities and arrangements, and the purchase of additional
facilities and capital equipment. CardioTech is currently conducting its
operations with approximately $2,226,691 in cash. CardioTech estimates such
amounts will be sufficient to fund its working capital and research and
development activities through June 1999.

                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                  (continued)
                                        
     CardioTech will seek to obtain additional funds through public or private
equity or debt financings, collaborative arrangements, or from other sources.
There can be no assurance that additional financing will be available at all or
on acceptable terms to permit successful commercialization of CardioTech's
technology and products in development. If adequate funds are not available,
CardioTech may be required to curtail significantly one or more of its research
and development programs, or obtain funds through arrangements with
collaborative partners or others that may require CardioTech to relinquish
rights to certain of its technologies, product candidates, or products.

UNCERTAINTIES

     The Company is subject to risks common to companies in the medical device
industry, including, but not limited to, development of new technology
innovations by competitors of the Company, dependence on key personnel,
protection of proprietary technology, and compliance with FDA government
regulations.

CASH AND CASH EQUIVALENTS

     Cash and Cash Equivalents include cash on hand, demand deposits and short
term investments with original maturities of three months or less.

ACCOUNTS RECEIVABLE - OTHER

     Accounts Receivable - Other principally consist of revenue receivable from
research and development work completed on National Institutes of Health Small
Business Innovative Research Grants, and Royalty Income Receivable.

RESEARCH REVENUES

     Research Revenues are generated in connection with the development and sale
of ChronoFlex and other proprietary biomaterials for use in medical devices. The
Company has also received royalty fees from Bard Access Systems. CardioTech
recognizes these fees as revenue in accordance with the terms of the contracts.
Contracted development fees from corporate partners are recognized upon
completion of service or the attainment of technical benchmarks, as appropriate.

     During the year ended March 31, 1998 and 1997, the Company was the
recipient of four Small Business Innovation Research (SBIR) grants, awarded by
the National Institute of Health to support the Company's research and
development programs. Revenue from these grants is recognized ratably over one
year which properly matches costs with related revenues.

                                  (continued)


RESEARCH AND DEVELOPMENT EXPENSES

     Research and development expenses are charged to expense as incurred.

DUE TO PARENT, ADVANCE FROM PARENT

     Prior to the June, 1996 Spin-Off, all inter-company charges related to
CardioTech's operations and all amounts receivable to and payable by CardioTech
were processed by PMI, and the net amount was recorded as Advance from Parent in
Stockholders' Equity. Amounts due to parent were permanently invested by PMI in
connection with the Common Stock Subscription Agreement discussed in Note C
below.

FOREIGN CURRENCY TRANSLATION

     In accordance with Statement of Financial Accounting Standard No. 52,
"Foreign Currency Translation," assets and liabilities of the Company's foreign
subsidiary are translated into US 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 Stockholders' Equity. Transaction gains and
losses are recorded in the Consolidated Statements of Operations.

EQUIPMENT AND LEASEHOLD IMPROVEMENTS

     Equipment and Leasehold improvements are stated at cost. Equipment is
depreciated using the straight-line method over the estimated useful lives of
the assets, ranging from five to seven years, and leasehold improvements are
amortized using the straight-line method over the shorter of the estimated life
of the asset or the remaining term of the lease. Expenditures for repairs and
maintenance are charged to expense as incurred. When assets are retired or
disposed of, the cost and accumulated depreciated thereon are removed from the
accounts and related gains and losses are included in operations.

BASIC AND DILUTED EARNINGS PER SHARE

     The Company computes basic and diluted earnings per share ("EPS") in
accordance with Statement of Financial Accountings Standards No. 128, "Earnings
Per Share", which the Company adopted on October 1, 1997. Basic earnings per
share is based upon the weighted average number of common shares outstanding
during the period. Diluted earnings per share is based upon the weighted average
number of common shares outstanding during the period plus additional weighted
average common equivalent shares outstanding during the period. Common
equivalent shares have been excluded from the computation of diluted loss per
share for all periods presented, as their effect would have been anti-dilutive.

                                      25
<PAGE>
 
Common equivalent shares result from the assumed exercise of outstanding stock
options and warrants, the proceeds of which are then assumed to have been used
to repurchase outstanding common stock using the treasury stock method.

     The following table reconciles the numerator and denominator of the basic
and diluted earnings per share computations shown on the Consolidated Statements
of Operations:

INCOME TAXES

     Deferred tax assets and liabilities are recognized 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. A valuation reserve against the net deferred assets is recorded, if,
based upon weighed available evidence, it is more likely than not that some or
all of the deferred tax assets will not be realized.

     The Company has no income tax provision for the years ended March 31, 1998
and 1997.

DEBT ISSUANCE COST

     The costs related to the issuance of debt are capitalized and amortized to
interest expense on a straight line basis over the life of the debt.

RECENT ACCOUNTING PRONOUNCEMENTS

     The Company will adopt Statement of Financial Accounting Standards No. 130 
"Reporting Comprehensive Income" in fiscal 1999. This Statement establishes 
standards for reporting and displaying comprehensive income and its components 
(revenues, 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 and additional paid-in capital in the equity section of the balance 
sheet. The Company believes that adoption of this Statement will not have a 
material effect on its financial statements.

    The Company will also adopt Statement of Financial Accounting Standards No.
131 "Disclosures About Segments of an Enterprise and Related Information" fiscal
1999. This statement supersedes FASB Statement No. 14, "Financial Reporting for
Segments of a Business Enterprise," but retains the requirement to report
information about major customers. This Statement establishes standards for
reporting information about operating segments in annual financial statements.
Operating segments are defined as components of an enterprise evaluated
regularly by the Company's senior management in deciding how to allocate
resources and in assessing performance. The Company believes that adoption of
this statement will not significantly change its segment reporting disclosures.

C.   ARRANGEMENTS WITH PMI AND SUBSIDIARIES:

     From CardioTech's inception until June 11, 1996, all facilities and support
services, including research and administrative support, were provided by PMI.
For these services, CardioTech was charged $1,792,500, $591,000 and $169,354 for
the years ended March 31, 1996, 1995 and for the period April 1, 1996 to June
11, 1996, respectively. These charges

                                      27
<PAGE>
 
represent an allocation of CardioTech's proportionate share of PMI's overhead
costs by PMI using formulas which management believed were reasonable based upon
CardioTech's use of facilities and services.

     In connection with the Spin Off, CardioTech entered into the following
agreements with PMI.

DISTRIBUTION AGREEMENT

     This agreement provided for the principal corporate transactions required
to effect the Spin Off, including, among other things, the preparation of a
registration statement registering the Common Stock under the Securities
Exchange Act of 1934, as amended, and an undertaking by CardioTech to prepare a
registration statement registering, under the Securities Act of 1933, as
amended, the shares of Common Stock to be issued upon the exercise of the
Warrants described in Note M.

     This agreement also allocated the costs related to the implementation of
the Spin Off between PMI and CardioTech and provided that each company would
share equally any liabilities under the federal and any state securities laws
incurred as a result of the distribution of the information statement relating
to the Spin Off.

     CardioTech agreed to reimburse PMI 50% of certain expenses incurred in
connection with the Distribution. CardioTech's portion of these expenses was
approximately $374,000 and were incurred in the fiscal year 1997. There were no
remaining spin-off costs in Fiscal year 1998.

                                  (continued)

LICENSE AGREEMENT

     PMI 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 PMI in the implantable devices and materials field
(collectively, "PMI Licensed Technology"). PMI, at its own expense, will file
patent or other applications for the protection of all new inventions
formulated, made or conceived by PMI during the term of the license that related
to PMI 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 PMI Licensed Technology and all such inventions shall be exclusively
licensed to PMI for use by PMI in fields other than the implantable devices and
materials field.

TAX MATTERS AGREEMENT

     The Tax Matters Agreement provides, among other things, that PMI will be
responsible for all federal, state, local and foreign tax liabilities of
CardioTech for periods ending on or prior to June 11, 1996 and CardioTech will
be responsible for all tax liabilities of CardioTech subsequent to that time.
The Tax Matters Agreement further provides that for the tax year of PMI that
includes June 11, 1996 and the tax year of CardioTech that commences immediately
following June 11, 1996, PMI will claim on its federal income tax returns
certain specified tax benefits and CardioTech will not claim any of such tax
benefits through June 11, 1996.

                                  (continued)


     On March 31, 1998, the Company issued $1,660,000, 7% Convertible Senior
Notes with a maturity date of March 20, 2003 to Dresdner, Kleinwort Benston
Private Partners LP ("DKB"). Interest will accrue annually and is payable
quarterly in cash and/or additional Notes at the option of DKB.

     At any time prior to maturity, DKB may convert the Notes, in whole or part,
plus accrued interest into Common Stock of the Company at a conversion price of
$1.995 which is subject to adjustment in certain events.

     Prior to maturity, the Notes are redeemable by the Company at a premium
which ranges from 105% to 100% of principal. Upon the occurrence of a change of
control, DKB may require the Company repurchase the Notes at a premium which
ranges from 105% to 100%. At maturity and under certain conditions, the Company
may repay the Notes, plus accrued interest, by converting them, in whole or in
part, into Common Stock of the Company at the conversion price.

     If the Company elects not to issue sufficient shares pursuant to the
conversion, redemption or repayment of the Notes, the balance of any amounts due
will be paid in cash, based upon the prevailing market price of the shares of
Common Stock not issued.

     CardioTech has the right to issue to DKB an additional $840,000 in 7% 
Convertible Senior Notes, provided certain milestones are attained prior to 
September 30, 1998.

maintenance of working capital and positive net worth, maintenance of share 
listing on the AMEX (or other acceptable national exchange) and receipt of an
unqualified audit opinion without a "going concern" paragraph. In the event of 
default the Notes may be accelerated.

L. STOCK OPTION DISCLOSURE:

     CardioTech's 1996 Employee, Director and Consultants Stock Option Plan (the
"Plan") was approved by CardioTech's Board of Directors and Stockholders in
March 1996, a total of approximately 1,167,000 shares have been reserved for
issuance under the Plan. Under the terms of the Plan the exercise price of
Incentive Stock Options issued under the Plan must be equal to the fair market
value of the Common Stock at date of grant. The options vest over 4 years. In
the event that Non Qualified Options are granted under the Plan the exercise
price may be less than the fair market value of the Common Stock at time of
grant (but not less than par value). On October 1, 1996, the Compensation
Committee of the Board of Directors of the Company, which administers the Plan,
repriced stock options to purchase 866,208 shares of Common Stock, at the fair
market value on the date of repricing.
 
     As permitted by Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation," ("SFAS 123"),  the Company applies
APB Opinion No. 25 and 

                                       33
<PAGE>
 
related Interpretations in accounting for the Plan. 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.

Activity under the Plans for the year ended March 31, 1998 is as follows:

Had compensation cost for the Company's 1998 and 1997 stock option grants been

     The effects 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.

M.  WARRANTS:

     In connection with the Spin Off, the Company issued warrants (the
"Warrants") to John Hancock Mutual Life Insurance Company to purchase up to
255,100 shares of Common Stock at $3.70 per share. The Warrants are exercisable
beginning on June 19, 1996 and expire on January 31, 2000. As a result of the
antidilutive provisions, CardioTech is required to issue additional warrants to
John Hancock when additional common shares or common share equivalents are
issued to third parties at a price lower than the exercise price. On March 31,
1998 the exercise price of the Warrants was adjusted to $3.41 per share and the
number of shares subject to the Warrants was adjusted to 276,656 shares.

O. SUBSEQUENT EVENTS

     On April 1, 1998 the Company's wholly owned subsidiary CardioTech
International, Ltd., signed a collaborative research and development agreement
with the Royal Free Hospital School of Medicine.  This research and development 
is funded by a loan of GBP 252,942 ($424,765) from Freemedic PLC, a subsidiary
of the Royal Free Hospital, to CardioTech International, Ltd. The loan has a
fixed rate of interest of 10% and both principal and interest are payable in
full before April 01, 2000.

     The loan is convertible, at Freemedic's option, into Common Stock of the
Company at $3.70 per share from April 1, 1998 until March 20, 2000. During this
period, the loan is also convertible at the Company's option into Common Stock
of the Company at $3.70 per share, provided that the market price for the
Company's Common Stock exceeds $3.70 from the day that the Company gives notice
of such conversion until seven business days thereafter. The loan is secured by
a pledge of all the assets of CardioTech International, Ltd. and is guaranteed
by the Company.

during the periods ended March 31, 1998 and 1997, respectively, were excluded
from the calculation of diluted earnings per share because the effect of their
inclusion would have been anti-dilutive.

2.   PURPOSES OF THE PLAN.
     -------------------- 

                                      -2-
<PAGE>
 
     The Plan is intended to encourage ownership of Shares by Key Employees,
directors and certain consultants to the Company in order to attract such
people, to induce them to work for the benefit of the Company or of an Affiliate
and to provide additional incentive for them to promote the success of the
Company or of an Affiliate. The Plan provides for the granting of ISOs and Non-
Qualified Options.

3.   SHARES SUBJECT TO THE PLAN.
     -------------------------- 

     The number of Shares subject to this Plan as to which Options may be
granted from time to time shall be equal to 1,061,029 Shares or the equivalent
of such number of Shares after the Administrator, in its sole discretion, has
interpreted the effect of any stock split, stock dividend, combination,
recapitalization or similar transaction in accordance with Paragraph 16 of the
Plan. Of the Shares subject to this Plan, 106,103 Shares shall be eligible for
grant under Paragraph 6(A)(e) hereof.

     If an Option ceases to be "outstanding", in whole or in part, the Shares
which were subject to such Option shall be available for the granting of other
Options under the Plan. Any Option shall be treated as "outstanding" until such
Option is exercised in full, or terminates or expires under the provisions of
the Plan, or by agreement of the parties to the pertinent Option Agreement.

4.   ADMINISTRATION OF THE PLAN.
     -------------------------- 

     The Administrator of the Plan will be the Board of Directors, except to the
extent the Board of Directors delegates its authority to the Committee, in which
case the Committee shall be the Administrator. Following the date on which the
Common Stock is registered under the Securities and Exchange Act of 1934, as
amended (the "1934 Act"), the Plan is intended to comply in all respects with
Rule 16b-3 or its successors, promulgated pursuant to Section 16 of the 1934 Act
with respect to Participants who are subject to Section 16 of the 1934 Act, and
any provision in this Plan with respect to such persons contrary to Rule 16b-3
shall be deemed null and void to the extent permissible by law and deemed
appropriate by the Administrator. Subject to the provisions of the Plan, the
Administrator is authorized to:

     a.   Interpret the provisions of the Plan or of any Option or Option
          Agreement and to make all rules and determinations which it deems
          necessary or advisable for the administration of the Plan;

     b.   Determine which employees of the Company or of an Affiliate shall be
          designated as Key Employees and which of the Key Employees, directors
          and consultants shall be granted Options;

     c.   Determine the number of Shares for which an Option or Options shall be
          granted; and

     d.   Specify the terms and conditions upon which an Option or Options may
          be granted;

                                      -3-
<PAGE>
 
provided, however, that all such interpretations, rules, determinations, terms
and conditions shall be made and prescribed in the context of preserving the tax
status under Section 422 of the Code of those Options which are designated as
ISOs. Subject to the foregoing, the interpretation and construction by the
Administrator of any provisions of the Plan or of any Option granted under it
shall be final, unless otherwise determined by the Board of Directors, if the
Administrator is the Committee.

5.   ELIGIBILITY FOR PARTICIPATION.
     ----------------------------- 

     The Administrator will, in its sole discretion, name the Participants in
the Plan, provided, however, that each Participant must be a Key Employee,
director or consultant of the Company or of an Affiliate at the time an Option
is granted. Members of the Board of Directors who are not employees of the
Company or of an Affiliate may receive options pursuant to Paragraph 6(A)(e) of
the Plan, but only pursuant thereto. Notwithstanding any of the foregoing
provisions, the Administrator may authorize the grant of an Option to a person
not then an employee, director or consultant of the Company or of an Affiliate.
The actual grant of such Option, however, shall be conditioned upon such person
becoming eligible to become a Participant at or prior to the time of the
execution of the Option Agreement evidencing such Option. ISOs may be granted
only to Key Employees. Non-Qualified Options may be granted to any Key Employee,
director or consultant of the Company or an Affiliate. In no event shall any
Employee be granted in any fiscal year Options to purchase more than 1,061,029
shares of Stock pursuant to this Plan. The granting of any Option to any
individual shall neither entitle that individual to, nor disqualify him or her
from, participation in any other grant of Options.

6.   TERMS AND CONDITIONS OF OPTIONS.
     ------------------------------- 

     Each Option shall be set forth in writing in an Option Agreement, duly
executed by the Company and, to the extent required by law or requested by the
Company, by the Participant. The Administrator may provide that Options be
granted subject to such conditions as the Administrator may deem appropriate,
including, without limitation, subsequent approval by the shareholders of the
Company of this Plan or any amendments to this Plan. The Option Agreements shall
be subject to at least the following terms and conditions:

     A.   Non-Qualified Options:  Each Option intended to be a Non-Qualified

          Option shall be subject to the terms and conditions which the
          Administrator determines to be appropriate and in the best interest of
          the Company, subject to the following minimum standards for any such
          Non-Qualified Option:

          a.   Option Price. Each Option Agreement shall state the option price

               (per share) of the Shares covered by each Option, which option
               price shall be determined by the Administrator but shall not be
               less than the par value per share of Common Stock;

          b.   Number of Shares. Each Option Agreement shall state the number of
               ----------------

          c.   Term of Option, Vesting. Each Option Agreement shall state the
               -----------------------                                       
               date or dates on which it first is exercisable and the date after
               which it may no longer be exercised, and may provide that the
               Option rights accrue or become exercisable in installments over a
               period of months or years, or upon the occurrence of certain
               conditions or the attainment of stated goals or events;

          d.   Option Conditions. Exercise of any Option may be conditioned upon
               -----------------                                           
               the Participant's execution of a Share purchase agreement in form
               satisfactory to the Administrator providing for certain
               protections for the Company and its other shareholders including
               requirements that:

               i.   The Participant's or the Participant's Survivors' right to
                    sell or transfer the Shares may be restricted; and

               ii.  The Participant or the Participant's Survivors may be
                    required to execute letters of investment intent and must
                    also acknowledge that the Shares will bear legends noting
                    any applicable restrictions.

          e.   Directors' Options.  Each director of the Company who is not an
               ------------------                                          
               employee of the Company or any Affiliate, who is first elected or
               appointed to the Board of Directors after the date on which the
               Common Stock is registered under the 1934 Act, upon such election
               or appointment and upon every anniversary thereof provided that
               on such dates such director has been in the continued and
               uninterrupted service of the Company as a director since his or
               her election or appointment and is a director of the Company and
               is not an employee of the Company at such times, shall be granted
               a Non-Qualified Option to purchase 14,854 Shares. Any non-
               employee director serving in office on the date on which the
               Common Stock is registered under the 1934 Act, who has been a
               member of the Board of Directors prior to such date shall be
               granted on such date and upon every anniversary thereof, a Non-
               Qualified Option to purchase 14,854 Shares, provided that on such
               date such director has been in the continued and uninterrupted
               service of the Company as a director since his or her election or
               appointment and is a director of the Company and is not an
               employee of the Company at such time. If any non-employee
               director should cease to be a director and thereafter shall be
               elected or appointed to the Board of Directors, upon such
               election or appointment and upon every anniversary thereof
               provided that on such dates such director has been in the
               continued and uninterrupted service of the Company as a director
               since his or her election or appointment and is a director of the
               Company and is not an employee of the Company at such times, such
               director shall be granted a Non-Qualified Option to purchase
               14,854 Shares. Each such Option shall (i) have an exercise price
               equal to the Fair Market Value (per share) of the Shares on the
               date of grant of the Option, (ii) have a term of ten (10) years,
               and (iii) shall become cumulatively exercisable in four (4) equal
               installments of twenty-five percent (25%) each, upon completion
               of three (3) months of service on the Board of Directors after
               the date of grant, and continuing upon completion of each of the
               next three (3) three (3)-month 

                                      -5-
<PAGE>
 
               periods of service thereafter (for example, if the date of grant
               of an Option was May 1, 1996, then the Option would vest in four
               (4) equal installments on August 1, 1996, November 1, 1996,
               February 1, 1997 and May 1, 1997). Any director entitled to
               receive an Option grant under this Subparagraph may elect to
               decline the Option. Notwithstanding the provisions of Paragraph
               23 concerning amendment of the Plan, the provisions of this
               Subparagraph shall not be amended more than once every six (6)
               months, other than to comport with changes in the Code, the
               Employee Retirement Income Security Act, or the rules thereunder.
               The provisions of Paragraphs 10, 11, 12 and 13 below shall not
               apply to Options granted pursuant to this Subparagraph.

     Except as otherwise provided in the pertinent Option Agreement, if a
director who received Options pursuant to this Subparagraph (e):

               i.   ceases to be a member of the Board of Directors for any
                    reason other than death or Disability, any then unexercised
                    Options granted to such director may be exercised by the
                    director within a period of ninety (90) days after the date
                    the director ceases to be a member of the Board of
                    Directors, but only to the extent of the number of Shares
                    with respect to which the Options are exercisable on the
                    date the director ceases to be a member of the Board of
                    Directors, and in no event later than the expiration date of
                    the Option; or

               ii.  ceases to be a member of the Board of Directors by reason of
                    his or her death or Disability, any then unexercised Options
                    granted to such director may be exercised by the director
                    (or by the Participant's personal representative, or
                    Participant's Survivors in the event of death) within a
                    period of one hundred eighty (180) days after the date the
                    director ceases to be a member of the Board of Directors,
                    but only to the extent of the number of Shares with respect
                    to which the Options are exercisable on the date the
                    director ceases to be a member of the Board of Directors,
                    and in no event later than the expiration date of the
                    Option.

               which ISOs are exercisable for the first time by the Participant
               in any calendar year does not exceed one hundred thousand dollars
               ($100,000), provided that this Subparagraph (d) shall have no
               force or effect if its inclusion in the Plan is not necessary for
               Options issued as ISOs to qualify as ISOs pursuant to Section
               422(d) of the Code.

          e.   Limitation on Grant of ISOs:  No ISOs shall be granted after

7.   EXERCISE OF OPTION AND ISSUE OF SHARES.
     -------------------------------------- 

     An Option (or any part or installment thereof) shall be exercised by giving
written notice to the Company at its principal office address, together with
provision for payment of the full purchase price in accordance with this
Paragraph for the Shares as to which such Option is being exercised, and upon
compliance with any other condition(s) set forth in the Option Agreement. Such
written notice shall be signed by the person exercising the Option, shall state
the number of Shares with respect to which the Option is being exercised and
shall contain any representation required by the Plan or the Option Agreement.
Payment of the purchase price for the Shares as to which such Option is being
exercised shall be made (a) in United States dollars in cash or by check, or (b)
at the discretion of the Administrator, through delivery of shares of Common
Stock having a fair market value equal as of the date of the exercise to the
cash exercise price of the Option, determined in good faith by the
Administrator, or (c) at the discretion of the Administrator, by delivery of the
grantee's personal recourse note bearing interest payable not less than annually
at no less than 100% of the applicable Federal rate, as defined in Section
1274(d) of the Code, or (d) at the discretion of the Administrator, in
accordance with a cashless exercise program established with a securities
brokerage firm, and approved by the Administrator or (e) at the discretion of
the Administrator, by any combination of (a), (b), (c) and (d) above.
Notwithstanding the foregoing, the Administrator shall accept only such payment
on exercise of an ISO as is permitted by Section 422 of the Code.

     The Company shall then reasonably promptly deliver the Shares as to which
such Option was exercised to the Participant (or to the Participant's Survivors,
as the case may be). In determining what constitutes "reasonably promptly," it
is expressly understood that the delivery of the Shares may be delayed by the
Company in order to comply with any law or regulation which requires the Company
to take any action with respect to the Shares prior to their issuance. The
Shares shall, upon delivery, be evidenced by an appropriate certificate or
certificates for fully paid, non-assessable Shares.

     In lieu of permitting a Participant to obtain Common Stock pursuant to the
exercise of an Option, the Company may, in its sole discretion, pay to the
Participant an amount equal to the Appreciated Value multiplied by the number of
shares of Common Stock that the Participant is entitled to upon the exercise of
an Option (the "Appreciated Amount"). The Appreciated Amount shall be payable to
the Participant within fifteen (15) days of receipt by the Company of the notice
from the Participant that the Participant intends to exercise the Option.
"Appreciated Value" shall mean the amount by which (i) the per share Fair Market
Value on the date of exercise of the Option, exceeds (ii) the option price per
share set forth in the related Option Agreement.

     The Administrator shall have the right to accelerate the date of exercise
of any installment of any Option; provided that the Administrator shall not
accelerate the exercise date of any installment of any Option granted to any Key
Employee as an ISO (and not previously converted into a Non-Qualified Option
pursuant to Paragraph 19) if such acceleration would violate the annual vesting
limitation contained in Section 422(d) of the Code, as described in Paragraph
6(B)(d).

     The Administrator may, in its discretion, amend any term or condition of an
outstanding

                                      -8-
<PAGE>
 
Option provided (i) such term or condition as amended is permitted by the Plan,
(ii) any such amendment shall be made only with the consent of the Participant
to whom the Option was granted, or in the event of the death of the Participant,
the Participant's Survivors, if the amendment is adverse to the Participant,
(iii) any such amendment of any ISO shall be made only after the Administrator,
after consulting the counsel for the Company, determines whether such amendment
would constitute a "modification" of any Option which is an ISO (as that term is
defined in Section 424(h) of the Code) or would cause any adverse tax
consequences for the holders of such ISO, and (iv) with respect to any Option
held by any Participant who is subject to the provisions of Section 16(a) of the
1934 Act, any such amendment shall be made only after the Administrator, after
consulting with counsel for the Company, determines whether such amendment would
constitute the grant of a new Option.

8.   RIGHTS AS A SHAREHOLDER.
     ----------------------- 

     No Participant to whom an Option has been granted shall have rights as a
shareholder with respect to any Shares covered by such Option, except after due
exercise of the Option and tender of the full purchase price for the Shares
being purchased pursuant to such exercise and registration of the Shares in the
Company's share register in the name of the Participant.

9.   ASSIGNABILITY AND TRANSFERABILITY OF OPTIONS.
     -------------------------------------------- 

     By its terms, an Option granted to a Participant shall not be transferable
by the Participant other than by will or by the laws of descent and distribution
or pursuant to a qualified domestic relations order as defined by the Code or
Title I of the Employee Retirement Income Security Act or the rules thereunder,
provided, however, that the designation of a beneficiary of an Option by a
Participant shall not be deemed a transfer prohibited by this Paragraph. Except
as provided in the preceding sentence, an Option shall be exercisable, during
the Participant's lifetime, only by such Participant (or by his or her legal
representative) and shall not be assigned, pledged or hypothecated in any way
(whether by operation of law or otherwise) and shall not be subject to
execution, attachment or similar process. Any attempted transfer, assignment,
pledge, hypothecation or other disposition of any Option or of any rights
granted thereunder contrary to the provisions of this Plan, or the levy of any
attachment or similar process upon an Option, shall be null and void.

10.  EFFECT OF TERMINATION OF SERVICE OTHER THAN "FOR CAUSE".
     ------------------------------------------------------- 

     Except as otherwise provided in the pertinent Option Agreement, in the
event of a termination of service (whether as an employee, director or
consultant) with the Company or an Affiliate before the Participant has
exercised all Options, the following rules apply:

     a.   A Participant who ceases to be an employee, director or consultant of
          the Company or of an Affiliate (for any reason other than termination
          "for cause," Disability, or death for which events there are special
          rules in Paragraphs 11, 12, and 13, respectively), may exercise any
          Option granted to him or her to the extent that the Option is
          exercisable on the date of such termination of service, but only
          within such term as the Administrator has designated in the pertinent
          Option

                                      -9-
<PAGE>
 
          Agreement.

     b.   In no event may an Option Agreement provide, if the Option is intended
          to be an ISO, that the time for exercise be later than three (3)
          months after the Participant's termination of employment.

     c.   The provisions of this Paragraph, and not the provisions of Paragraph
          12 or 13, shall apply to a Participant who subsequently becomes
          disabled or dies after the termination of employment, director status
          or consultancy, provided, however, in the case of a Participant's
          death within three (3) months after the termination of employment,
          director status or consulting, the Participant's Survivors may
          exercise the Option within one (1) year after the date of the
          Participant's death, but in no event after the date of expiration of
          the term of the Option.

     d.   Notwithstanding anything herein to the contrary, if subsequent to a
          Participant's termination of employment, director status or
          consultancy, but prior to the exercise of an Option, the Board of
          Directors determines that, either prior or subsequent to the
          Participant's termination, the Participant engaged in conduct which
          would constitute "cause," then such Participant shall forthwith cease
          to have any right to exercise any Option.

     e.   A Participant to whom an Option has been granted under the Plan who is
          absent from work with the Company or with an Affiliate because of
          temporary disability (any disability other than a permanent and total
          Disability as defined in Paragraph 1 hereof), or who is on leave of
          absence for any purpose, shall not, during the period of any such
          absence, be deemed, by virtue of such absence alone, to have
          terminated such Participant's employment, director status or
          consultancy with the Company or with an Affiliate, except as the
          Administrator may otherwise expressly provide.

     f.   Options granted under the Plan shall not be affected by any change of
          employment or other service within or among the Company and any
          Affiliates, so long as the Participant continues to be an employee,
          director or consultant of the Company or any Affiliate, provided,
          however, if a Participant's employment by either the Company or an
          Affiliate should cease (other than to become an employee of an
          Affiliate or the Company), such termination shall affect the
          Participant's rights under any Option granted to such Participant in
          accordance with the terms of the Plan and the pertinent Option
          Agreement.

11.  EFFECT OF TERMINATION OF SERVICE "FOR CAUSE".
     -------------------------------------------- 

     Except as otherwise provided in the pertinent Option Agreement, the
following rules apply if the Participant's service (whether as an employee,
director or consultant) with the Company or an Affiliate is terminated "for
cause" prior to the time that all of his or her outstanding Options have been
exercised:

     a.   All outstanding and unexercised Options as of the date the Participant
          is notified that his or her service is terminated "for cause" will
          immediately be forfeited, unless the Option Agreement provides
          otherwise.

                                     -10-
<PAGE>
 
     b.   For purposes of this Paragraph, "cause" shall include (and is not
          limited to) dishonesty with respect to the Company or any Affiliate,
          insubordination, substantial malfeasance or non-feasance of duty,
          unauthorized disclosure of confidential information, and conduct
          substantially prejudicial to the business of the Company or any
          Affiliate. The determination of the Administrator as to the existence
          of cause will be conclusive on the Participant and the Company.

     c.   "Cause" is not limited to events which have occurred prior to a
          Participant's termination of service, nor is it necessary that the
          Administrator's finding of "cause" occur prior to termination. If the
          Administrator determines, subsequent to a Participant's termination of
          service but prior to the exercise of an Option, that either prior or
          subsequent to the Participant's termination the Participant engaged in
          conduct which would constitute "cause," then the right to exercise any
          Option is forfeited.

     d.   Any definition in an agreement between the Participant and the Company
          or an Affiliate, which contains a conflicting definition of "cause"
          for termination and which is in effect at the time of such
          termination, shall supersede the definition in this Plan with respect
          to such Participant.

12.  EFFECT OF TERMINATION OF SERVICE FOR DISABILITY.
     ----------------------------------------------- 

     Except as otherwise provided in the pertinent Option Agreement, a
Participant who ceases to be an employee, director or consultant of the Company
or of an Affiliate by reason of Disability may exercise any Option granted to
such Participant:

     a.   To the extent exercisable but not exercised on the date of Disability;
          and

     b.   In the event rights to exercise the Option accrue periodically, to the
          extent of a pro rata portion of any additional rights as would have
          accrued had the Participant not become Disabled prior to the end of
          the accrual period which next ends following the date of Disability.
          The proration shall be based upon the number of days of such accrual
          period prior to the date of Disability.

     A Disabled Participant may exercise such rights only within a period of not
more than one (1) year after the date that the Participant became Disabled,
notwithstanding that the Participant might have been able to exercise the Option
as to some or all of the Shares on a later date if he or she had not become
disabled and had continued to be an employee, director or consultant or, if
earlier, within the originally prescribed term of the Option.

     The Administrator shall make the determination both of whether Disability
has occurred and the date of its occurrence (unless a procedure for such
determination is set forth in another agreement between the Company and such
Participant, in which case such procedure shall be used for such determination).
If requested, the Participant shall be examined by a physician selected or
approved by the Administrator, the cost of which examination shall be paid for
by the Company.

                                     -11-

13.  EFFECT OF DEATH WHILE AN EMPLOYEE, DIRECTOR OR CONSULTANT.
     --------------------------------------------------------- 

     Except as otherwise provided in the pertinent Option Agreement, in the
event of the death of a Participant to whom an Option has been granted while the
Participant is an employee, director or consultant of the Company or of an
Affiliate, such Option may be exercised by the Participant's Survivors:

     a.   To the extent exercisable but not exercised on the date of death; and

     b.   In the event rights to exercise the Option accrue periodically, to the
          extent of a pro rata portion of any additional rights which would have
          accrued had the Participant not died prior to the end of the accrual
          period which next ends following the date of death. The proration
          shall be based upon the number of days of such accrual period prior to
          the Participant's death.

     If the Participant's Survivors wish to exercise the Option, they must take
all necessary steps to exercise the Option within one (1) year after the date of
death of such Participant, notwithstanding that the decedent might have been
able to exercise the Option as to some or all of the Shares on a later date if
he or she had not died and had continued to be an employee, director or
consultant or, if earlier, within the originally prescribed term of the Option.

14.  PURCHASE FOR INVESTMENT.
     ----------------------- 

     Unless the offering and sale of the Shares to be issued upon the particular
exercise of an Option shall have been effectively registered under the
Securities Act of 1933, as now in force or hereafter amended (the "1933 Act"),
the Company shall be under no obligation to issue the Shares covered by such
exercise unless and until the following conditions have been fulfilled:

     a.   The person(s) who exercise such Option shall warrant to the Company,
          prior to the receipt of such Shares, that such person(s) are acquiring
          such Shares for their own respective accounts, for investment, and not
          with a view to, or for sale in connection with, the distribution of
          any such Shares, in which event the person(s) acquiring such Shares
          shall be bound by the provisions of the following legend which shall
          be endorsed upon the certificate(s) evidencing their Shares issued
          pursuant to such exercise or such grant:

               The shares represented by this certificate have been taken for
               investment and they may not be sold or otherwise transferred by
               any person, including a pledgee, unless (1) either (a) a
               Registration Statement with respect to such shares shall be
               effective under the Securities Act of 1933, as amended, or (b)
               the Company shall have received an opinion of counsel
               satisfactory to it that an exemption from registration under such
               Act is then available, and (2) there shall have been compliance
               with all applicable state securities laws.

     b.   The Company shall have received an opinion of its counsel that the
          Shares may be issued upon such particular exercise in compliance with
          the 1933 Act without registration thereunder.

     The Company may delay issuance of the Shares until the completion of any
action or the attainment of any consent which the Company deems necessary under
any applicable law (including, without limitation, state securities or "blue
sky" laws).

15.  DISSOLUTION OR LIQUIDATION OF THE COMPANY.
     ----------------------------------------- 

     Upon the dissolution or liquidation of the Company, all Options granted
under this Plan which as of such date shall not have been exercised will
terminate and become null and void; provided, however, that if the rights of a
Participant or a Participant's Survivors have not otherwise terminated and
expired, the Participant or the Participant's Survivors will have the right
immediately prior to such dissolution or liquidation to exercise any Option to
the extent that the Option is exercisable as of the date immediately prior to
such dissolution or liquidation.

16.  ADJUSTMENTS.
     ----------- 

     Upon the occurrence of any of the following events, a Participant's rights
with respect to any Option granted to him or her hereunder which have not
previously been exercised in full shall be adjusted as hereinafter provided,
unless otherwise specifically provided in the pertinent Option Agreement:

     A.   Stock Dividends and Stock Splits.  If the shares of Common Stock shall
          --------------------------------                                
be subdivided or combined into a greater or smaller number of shares or if the
Company shall issue any shares of Common Stock as a stock dividend on its
outstanding Common Stock, the number of shares of Common Stock deliverable upon
the exercise of such Option shall be appropriately increased or decreased
proportionately, and appropriate adjustments shall be made in the purchase price
per share to reflect such subdivision, combination or stock dividend. The number
of Shares subject to Non-Qualified Options to be granted to directors pursuant
to Paragraph 6(A)(e) shall also be proportionately adjusted upon the occurrence
of such events.

     B.   Consolidations or Mergers.  If the Company is to be consolidated with
          -------------------------                                       
or acquired by another entity in a merger, sale of all or substantially all of
the Company's assets or otherwise (an "Acquisition"), the Administrator or the
board of directors of any entity assuming the obligations of the Company
hereunder (the "Successor Board"), shall, as to outstanding Options, either (i)
make appropriate provision for the continuation of such Options by substituting
on an equitable basis for the Shares then subject to such Options either the
consideration payable with respect to the outstanding shares of Common Stock in
connection with the Acquisition or securities of any successor or acquiring
entity; or (ii) upon written notice to the Participants, provide that all
Options must be exercised (either to the extent then exercisable or, at the
discretion of the Administrator, all Options being made fully exercisable for
purposes of this Subparagraph), within a specified number of days of the date of
such notice, at the end of which period the Options shall terminate; or (iii)
terminate all Options in exchange for a cash payment equal to the excess of the
Fair Market Value of the Shares subject to such Options (either to the extent
then exercisable or, at the discretion of the Administrator, all Options being
made fully exercisable for purposes of this Subparagraph) over the exercise
price thereof.

     C.   Recapitalization or Reorganization.  In the event of a 
          ----------------------------------                    
recapitalization or reorganization of the Company (other than a transaction
described in Subparagraph B above) pursuant to which securities of the Company
or of another corporation are issued with respect to the outstanding shares of
Common Stock, a Participant upon exercising an Option shall be entitled to
receive for the purchase price paid upon such exercise the securities he or she
would have received if he or she had exercised such Option prior to such
recapitalization or reorganization.

                                     -14-
<PAGE>
 
     D.   Modification of ISOs.  Notwithstanding the foregoing, any adjustments
          --------------------                                     
made pursuant to Subparagraph A, B or C with respect to ISOs shall be made only
after the Administrator, after consulting with counsel for the Company,
determines whether such adjustments would constitute a "modification" of such
ISOs (as that term is defined in Section 424(h) of the Code) or would cause any
adverse tax consequences for the holders of such ISOs. If the Administrator
determines that such adjustments made with respect to ISOs would constitute a
modification of such ISOs, it may refrain from making such adjustments, unless
the holder of an ISO specifically requests in writing that such adjustment be
made and such writing indicates that the holder has full knowledge of the
consequences of such "modification" on his or her income tax treatment with
respect to the ISO.

17.  ISSUANCES OF SECURITIES.
     ----------------------- 

     Except as expressly provided herein, no issuance by the Company of shares
of stock of any class, or securities convertible into shares of stock of any
class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares subject to Options. Except as
expressly provided herein, no adjustments shall be made for dividends paid in
cash or in property (including without limitation, securities) of the Company.

18.  FRACTIONAL SHARES.
     ----------------- 

     No fractional share shall be issued under the Plan and the person
exercising such right shall receive from the Company cash in lieu of such
fractional share equal to the Fair Market Value thereof.

19.  CONVERSION OF ISOs INTO NON-QUALIFIED OPTIONS; TERMINATION OF ISOs.
     ------------------------------------------------------------------

     The Administrator, at the written request of any Participant, may in its
discretion take such actions as may be necessary to convert such Participant's
ISOs (or any portions thereof) that have not been exercised on the date of
conversion into Non-Qualified Options at any time prior to the expiration of
such ISOs, regardless of whether the Participant is an employee of the Company
or an Affiliate at the time of such conversion. Such actions may include, but
not be limited to, extending the exercise period or reducing the exercise price
of the appropriate installments of such Options. At the time of such conversion,
the Administrator (with the consent of the Participant) may impose such
conditions on the exercise of the resulting Non-Qualified Options as the
Administrator in its discretion may determine, provided that such conditions
shall not be inconsistent with this Plan. Nothing in the Plan shall be deemed to
give any Participant the right to have such Participant's ISOs converted into
Non-Qualified Options, and no such conversion shall occur until and unless the
Administrator takes appropriate action. The Administrator, with the consent of
the Participant, may also terminate any portion of any ISO that has not been
exercised at the time of such termination.

                                     -15-

20.  WITHHOLDING.
     ----------- 

     In the event that any federal, state, or local income taxes, employment
taxes, Federal Insurance Contributions Act ("F.I.C.A.") withholdings or other
amounts are required by applicable law or governmental regulation to be withheld
from the Option holder's salary, wages or other remuneration in connection with
the exercise of an Option or a Disqualifying Disposition (as defined in
Paragraph 21), the Option holder shall advance in cash to the Company, or to any
Affiliate of the Company which employs or employed the Option holder, the amount
of such withholdings unless a different withholding arrangement, including the
use of shares of the Company's Common Stock, is authorized by the Administrator
(and permitted by law), provided, however, that with respect to persons subject
to Section 16 of the 1934 Act, any such withholding arrangement shall be in
compliance with any applicable provisions of Rule 16b-3 promulgated under
Section 16 of the 1934 Act. For purposes hereof, the fair market value of the
shares withheld for purposes of payroll withholding shall be determined in the
manner provided in Paragraph 1 above, as of the most recent practicable date
prior to the date of exercise. If the fair market value of the shares withheld
is less than the amount of payroll withholdings required, the Option holder may
be required to advance the difference in cash to the Company or the Affiliate
employer. The Administrator in its discretion may condition the exercise of an
Option for less than the then Fair Market Value on the Participant's payment of
such additional withholding.

21.  NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION.
     ---------------------------------------------- 

     Each Key Employee who receives an ISO must agree to notify the Company in
writing immediately after the Key Employee makes a Disqualifying Disposition of
any Shares acquired pursuant to the exercise of an ISO. A Disqualifying
Disposition is any disposition (including any sale) of such Shares before the
later of (a) two years after the date the Key Employee was granted the ISO, or
(b) one year after the date the Key Employee acquired Shares by exercising the
ISO. If the Key Employee has died before such stock is sold, these holding
period requirements do not apply and no Disqualifying Disposition can occur
thereafter.

22.  TERMINATION OF THE PLAN.
     ----------------------- 

     The Plan will terminate on March 4, 2006. The Plan may be terminated at an
earlier date by vote of the shareholders of the Company; provided, however, that
any such earlier termination will not affect any Options granted or Option
Agreements executed prior to the effective date of such termination.

                                     -16-

23.  AMENDMENT OF THE PLAN AND AGREEMENTS.
     ------------------------------------ 

     The Plan may be amended by the shareholders of the Company. The Plan may
also be amended by the Administrator, including, without limitation, to the
extent necessary to qualify any or all outstanding Options granted under the
Plan or Options to be granted under the Plan for favorable federal income tax
treatment (including deferral of taxation upon exercise) as may be afforded
ISOs, to the extent necessary to ensure the qualification of the Plan under Rule
16b-3, at such time, if any, as the Company has a class of stock registered
pursuant to Section 12 of the 1934 Act, and to the extent necessary to qualify
the shares issuable upon exercise of any outstanding Options granted, or Options
to be granted, under the Plan for listing on any national securities exchange or
quotation in any national automated quotation system of securities dealers. Any
amendment approved by the Administrator which is of a scope that requires
shareholder approval in order to ensure favorable federal income tax treatment

                                    -------


     This Employment Agreement (this "Agreement"), dated as of the 26th day of
March, 1998, is entered into by and between CardioTech International, Inc., a
Massachusetts corporation having its principal place of business at 11 State
Street, Woburn, Massachusetts 01801 (the "Company"), and Michael Szycher, Ph.D.,
an individual with an address at 2 Durham Drive, Lynnfield, Massachusetts 01940
(the "Executive").

                              TERMS OF AGREEMENT
                              ------------------

     In consideration of this Agreement and the continued employment of the
Executive by the Company, the parties agree as follows:

     1.   Employment.  The Company hereby employs the Executive, on a full-time
          ----------                                                      
basis, to act as Chief Executive Officer of the Company and to perform such acts
and duties and furnish such services to the Company in connection with and
related to that position as is customary for persons with similar positions in
like companies, and as the Board of Directors of the Company (the "Board") shall
from time to time reasonably direct. The Executive shall be an officer of the
Company. The Company also agrees to use its best efforts to cause the Executive
to be elected a member, and the Chairman, of the Board. The Executive hereby
accepts said employment. The Executive shall use his best and most diligent
efforts to promote the interests of the Company; shall discharge his duties in a
highly competent manner; and shall devote his full business time and his best
business judgment, skill and knowledge to the performance of his duties and
responsibilities hereunder. The Executive shall report directly to the Board.
Nothing contained herein shall preclude the Executive from devoting incidental
and insubstantial amounts of time to activities other than the business of the
Company.

     2.   Term of Employment.  The Company agrees to employ the Executive for 
          ------------------                                             
the period commencing on May 13, 1998 and ending on May 13, 2000 (the
"Employment Period"). Notwithstanding the foregoing, both the Executive and the
Company shall have the right to terminate the Executive's employment under this
Agreement upon thirty (30) days written notice to the other party, subject to
the Company's obligation to pay severance benefits under certain circumstances
as provided in Sections 3.6 and 3.7 hereof. If the Executive shall remain in the
employ of the Company beyond the Employment Period, in the absence of any other
express agreement between the parties, this Agreement shall be deemed to
continue on a month-to-month basis (the "Extended Employment Period").

pay the Executive an annualized base salary of One Hundred Eighty-Seven Thousand

required payroll deductions and state and federal withholdings. The Base Salary
may be adjusted from time to time in the sole discretion of the Board, except

Base Salary shall be reviewed annually by the Board.

          3.2.   Bonus Payment.  During the Employment Period, the Executive may

receive, in the sole discretion of the Compensation Committee of the Board (the
"Compensation Committee"), an annual bonus payment in an amount, if any, to be

                 ------------------                                            
Executive shall receive such benefits as are customarily provided to other

following benefits:

          (a)    Health Insurance.  Non-contributory health insurance pursuant

          (b)    Life Insurance.  Life insurance on the life of the Executive 
                 --------------                                              
with an Executive-directed beneficiary in the amount of one hundred fifty
percent (150%) of the Base Salary.

          3.4.   Vacation.  The Executive may take four weeks of paid vacation
                 --------                                                     
during each year at such times as shall be consistent with the Company's
vacation policies and (in the Board's judgment) with the Company's vacation
schedule for officers and other employees.

          3.5.   Disability or Death.   If during the Employment Period, the
                 -------------------                                        
Executive shall (i) become ill, disabled or otherwise incapacitated so as to be
unable to perform his usual duties (a) for a period in excess of one hundred
twenty (120) consecutive days or (b) for more than one hundred eighty (180) days
in any consecutive twelve (12) month period, or (ii) die, then the Company shall
have the right to terminate this Agreement, in accordance with applicable laws,
on thirty (30) days written

                                      -2-
<PAGE>
 
notice to the Executive or his estate.

          3.6.   Severance Payment.  In the event (i) the Company terminates 
                 -----------------                                            
this Agreement without Cause (i.e., other than pursuant to Section 3.5 or
Section 4 hereof) at any time (including during the Extended Employment Period,
or (ii) the Executive terminates his employment for Good Reason following a
Change in Control of the Company, or (iii) the Company fails to renew this
Agreement within two (2) years following the occurrence of a Change in Control,
the Company shall pay the Executive a severance payment equal to the Executive's
then current Base Salary multiplied by 2.99; such severance payment to be
adjusted to the extent necessary to avoid such payment being treated as an
"excess parachute payment" for purposes of Section 280G of the Internal Revenue
Code of 1986.

     "Good Reason" shall mean, during the nine (9) month period following a
Change in Control, (1) a good faith determination by the Executive that as a
result of such Change in Control he is not able to discharge his duties
effectively or (2) without the Executive's express written consent, the
occurrence of any of the following circumstances: (a) the assignment to the
Executive of any duties inconsistent (except in the nature of a promotion) with
the position in the Company that he held immediately prior to the Change in
Control or a substantial adverse alteration in the nature or status of his
position or responsibilities or the conditions of his employment from those in
effect immediately prior to the Change in Control; (b) a reduction by the
Company in the Base Salary as in effect on the date of the Change in Control;
(c) the Company's requiring the Executive to be based more than twenty-five (25)
miles from the Company's offices at which he was principally employed
immediately prior to the date of the Change in Control except for required
travel on the Company's business to an extent substantially consistent with his
present business travel obligations; or (d) the failure by the Company to
continue in effect any material compensation or benefit plan in which the
Executive participates immediately prior to the Change in Control unless an
equitable arrangement (embodied in an ongoing substitute or alterative plan) has
been made with respect to such plan, or the failure by the Company to continue
the Executive's participation therein (or in such substitute or alterative plan)
on a basis not materially less favorable, both in terms of the amount of
benefits provided and the level of his participation relative to other
participants, than existed at the time of the Change in Control. The Executive's
continued employment shall not constitute consent to, or a waiver of rights with
respect to, any circumstance constituting Good Reason hereunder.

     For purposes of this Agreement, a "Change in Control" shall 

                                      -3-
<PAGE>
 
occur or be deemed to have occurred only if any of the following events occur:
(i) any "person," as such term is used in Sections 13(d) and 14(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), (other than
any majority owned subsidiary thereof, the Company, any trustee or other
fiduciary holding securities under an employee benefit plan of the Company, any
trustee or other fiduciary of a trust treated for federal income tax purposes as
a grantor trust of which the Company is the grantor, or any corporation owned
directly or indirectly by the stockholders of the Company in substantially the
same proportion as their ownership of stock of the Company) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Company representing 50% or more of the
combined voting power of the Company's then outstanding securities on any matter
which could come before its stockholders for approval; (ii) individuals who, as
of the date hereof, constitute the Board (the "Incumbent Board") cease for any
reason to constitute at least a majority of the Board, provided that any person
becoming a director subsequent to the date hereof whose election, or nomination
for election by the Company's stockholders, was approved by a vote of at least a
majority of the directors then comprising the Incumbent Board (other than an
election or nomination of an individual whose initial assumption of office is in
connection with an actual or threatened election contest relating to the
election of the directors of the Company, as such terms are used in Rule 14a-11
of Regulation 14A under the Exchange Act) shall be, for purposes of this
Agreement, considered as though such person were a member of the Incumbent
Board; (iii) the stockholders of the Company approve a merger or consolidation
of the Company with any other corporation, other than (A) a merger or
consolidation which would result in the voting securities of the Company
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) more than 80% of the combined voting power of the voting
securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation or (B) a merger or consolidation effected to
implement a recapitalization of the Company (or similar transaction) in which no
"person" (as hereinabove defined) acquires more than 50% of the combined voting
power of the Company's then outstanding securities; or (iv) the stockholders of
the Company approve a plan of complete liquidation of the Company or an
agreement for the sale or disposition by the Company of all or substantially all
of the Company's assets.

          3.7.   Benefits After Termination.  Except as otherwise required by
                 --------------------------                                  
law, the Executive shall not be entitled to any employee benefits provided under
Section 3.3 hereof after termination of the employment of the Executive, whether
or not 

                                      -4-
<PAGE>
 
severance pay is being provided, except that if the Executive is entitled to the
severance payment described in Section 3.6 of this Agreement, (i) the Company
shall continue in full force and effect, at its expense, the life insurance
provided for in Section 3.3(b) hereof for a period of one (1) year after
termination of the Executive's employment hereunder or until the Executive
becomes employed, whichever first occurs, and (ii) during the six (6) month
period following the termination of the Executive's employment, the Company
shall reimburse the Executive for out-of-pocket health insurance expenses
incurred by the Executive pursuant to the Consolidated Omnibus Budget
Reconciliation Act of 1986 ("COBRA"). If the Executive elects not to maintain
health insurance pursuant to COBRA, the Company is under no obligation to
reimburse the Executive for his otherwise elected coverage. The Executive shall
be obligated to give the Company prompt notice of his employment.

     4.   Discharge for Cause.  The Company may discharge the Executive and

terminate his employment under this Agreement for Cause without further
liability to the Company by a majority vote of the Board, except that Executive,
if a Director, shall not be entitled to vote thereon. As used in this Agreement,
"Cause" shall mean any or all of the following:

          (a)  misconduct of the Executive during the course of his employment
which is materially injurious to the Company and which is brought to the
attention of the Executive promptly after discovery by the Company, including
but not limited to, theft or embezzlement from the Company, the intentional
provision of services to competitors of the Company, or improper disclosure of
proprietary information, but not including any act or failure to act by the
Executive that he believed in good faith to be proper conduct not adverse to his
duties hereunder;

          (b)  willful disregard or neglect by the Executive of his duties or of
the Company's interests that continues after being brought to the attention of
the Executive;

          (c)  unavailability (except as provided in Section 3.5 hereof) of the
Executive to substantially perform the duties provided for herein;

          (d)  conviction of a fraud or felony or any criminal offense involving
dishonesty, breach of trust or moral turpitude during the Executive's
employment;

          (e)  the Executive's breach of any of the material terms of this
Agreement (including the failure of the Executive to discharge his duties in a
highly competent manner) or any of the agreements executed in connection
herewith as enumerated in

                                      -5-

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

Sections 3.6 and 3.7 hereof, by a majority vote of the Board. The Executive, if
a Director, shall not be entitled to vote on the termination of this Agreement
without Cause.

     6.   Expenses.  Pursuant to the Company's customary policies in force at 
          --------

presentation of vouchers or receipts therefor, for all authorized expenses
properly incurred by him on the Company's behalf in the performance of his
duties hereunder.

Agreement (the "Confidential and Proprietary Information Agreement"),
substantially in the forms attached hereto as Exhibits A and B. The agreements
                                              ----------------

the entire understanding of the parties in respect of its subject matter and
supersedes all prior agreements and understandings between the parties with
respect to such subject matter; provided, however, that nothing in this

supplemented, cancelled or discharged, except by written instrument executed by
the party affected thereby. No failure to exercise, and no delay in exercising,
any right, power or privilege hereunder shall operate as a waiver thereof. No
waiver of any breach of any provision of this Agreement shall be deemed to be a
waiver of any preceding or succeeding breach of the same or any other
provisions.

          10.3.  Binding Effect; Assignment.  The rights and obligations of this
                 --------------------------                                     
Agreement shall bind and inure to the benefit of any successor of the Company by

reference purposes only and shall not affect the meaning or interpretation of
this Agreement.

          10.5.  Governing Law; Interpretation.  This Agreement shall be
                 -----------------------------

public policy of the Commonwealth of Massachusetts applicable to contracts
executed and to be wholly performed within such Commonwealth. Service of process
in any dispute shall be effective (a) upon the Company, if service is made on
any officer of the Company other than the Executive; (b) upon the Executive, if

all such further acts, deeds, assignments, transfers, conveyances, powers of
attorney

                                      -7-

intent of this Agreement.

                 ------------                                               
covenants or restrictions of this Agreement shall be determined by a court of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions, covenants and restrictions of this Agreement shall remain
in full force and effect and shall in no way be affected, impaired or
invalidated. If, moreover, any one or more of the provisions contained in this
Agreement shall for any reason be determined by a court of competent
jurisdiction to be excessively broad as to duration, geographical scope,
activity or subject, it shall be construed by limiting or reducing it so as to
be enforceable to the extent compatible with then applicable law.

                                   EXECUTION

                           AGREEMENT NOT TO COMPETE
                           ------------------------

     I recognize that CardioTech International, Inc., a Massachusetts
corporation (the "Company", which term shall include its subsidiaries and
affiliated entities), desires to retain me in its employ and that the Company
wishes to ensure that I do not compete with the Company, as specified below, in
the event my employment with the Company is terminated.

     In consideration of the Company's employment or continued employment of me,
I agree as follows:

     1.   I will not, for a period of one (1) year commencing with the
termination of my employment with the Company, engage (directly or indirectly)
in any activities or render any services similar or reasonably related to those
in which I shall have engaged or those which I shall have rendered as an
employee of the Company during any part of the two-year period preceding my
termination for any trade or business which directly competes with the Company
in any place where the Company does or may do business in any line of business
engaged in (or planned to be engaged in) by the Company, whether now existing or
hereafter established, nor shall I engage in such activities nor render such
services for any other person or entity engaged or about to become engaged in
such activities to, for or on behalf of any such trade or business.

     2.   I agree that for a period of one (1) year following termination of my
employment with the Company, I will not solicit or in any manner encourage
employees of the Company to leave their employ. I further agree that during such
period I will not offer or cause to be offered employment to any person who was
employed by the Company at any time during the six (6) months prior to the
termination of my employment with the Company.

     3.   For purposes of this Agreement, "termination of employment" shall mean
voluntary termination by me or termination by the Company for "cause" (as that
term is defined in an Employment Agreement of even date herewith between me and
the Company).

     4.   I understand that nothing in this Agreement shall affect my
obligations under the "Confidential and Proprietary Information Agreement"
between the Company and myself of even date herewith.

     5.   I agree that in addition to any other rights and remedies available to
the Company for any breach by me of my obligations hereunder, the Company shall
be entitled to enforcement of my obligations hereunder by court injunction.

     6.   If any provision of this Agreement shall be declared invalid, illegal
or unenforceable, then such provision shall be enforceable to the extent that a
court shall deem it reasonable to enforce such provision. If such provision
shall be unreasonable to enforce to any extent, such provision shall be severed
from this Agreement and all remaining provisions shall continue in full force
and effect. 

                                      -9-

     This Agreement shall be governed in all respects by the laws of the

              CONFIDENTIAL AND PROPRIETARY INFORMATION AGREEMENT
              --------------------------------------------------


     In consideration of my employment by CardioTech International, Inc., a
Massachusetts corporation (the "Company"), I hereby agree as follows:

     1.   I will make full and prompt disclosure to the Company of all
inventions, improvements, modifications, discoveries, methods, data, ideas and
developments (all of which are collectively termed "developments" hereinafter),
whether patentable or not, made or conceived or reduced to practice or learned
by me either alone or jointly with others or under my direction during the
period of my employment, whether or not made or conceived during normal working
hours or on the premises of the Company. I do not have any developments other
than those I have already disclosed to you.

     2.   I agree that all developments covered by Paragraph 1 shall be the sole
property of the Company and its assigns, and the Company and its assigns shall
be the sole owner of all patents and other rights in connection therewith. I
hereby assign to the Company any rights in connection therewith. I hereby assign
to the Company any rights I may have or acquire in all developments. I further
agree as to all developments to assist the Company in every proper way (but at
the Company's expense) to obtain and from time to time enforce patents in
developments in any and all countries, and to that end I will execute all
documents for use in applying for and obtaining such patents thereon and
enforcing same, as the Company may desire, together with any assignments thereof
to the Company or persons designated by it. My obligation to assist the Company
in obtaining and enforcing patents for developments in any and all countries
shall continue beyond the termination of my employment, but the Company shall
compensate me at a reasonable rate after such termination for time actually
spent by me at the Company's request on such assistance.

          I understand that this Paragraph 2 does not apply to developments for
which no equipment, supplies, facility or trade secret information of the
Company was used and which was developed entirely on my own time, and (a) which
does not relate (1) to the business of the Company or (2) to the Company's
actual or demonstrable anticipated research or development, and (b) which does
not result from any work performed by me for the Company, but I agree that the
Company shall have a non-exclusive royalty-free license to use such developments
for all purposes.

     3.   I hereby represent that, to the best of my knowledge, I have no
present obligation to assign to any former employer or any other person,
corporation or firm, any development covered by Paragraph 2, EXCEPT AS I MAY BE
                                                           --------------------
OBLIGATED TO ASSIGN TO POLYMEDICA INDUSTRIES, INC. ("PMI") DEVELOPMENTS WHICH I
- -------------------------------------------------------------------------------
MAY HAVE CONCEIVED WHILE EMPLOYED BY PMI AND WHICH ARE REDUCED TO PRACTICE WHILE
- --------------------------------------------------------------------------------
I AM EMPLOYED BY THE COMPANY. I represent that my performance of all the terms
- ----------------------------                                                   
of this Agreement as an employee of the Company does not and will not breach any
agreement to keep in confidence proprietary information acquired by me in
confidence or in trust prior to my employment by the Company. I have not entered
into, and I agree I will not enter into, any agreement (either written or oral)
in conflict herewith.

     4.   I will also assign to the Company any and all copyrights and
reproduction rights to any material prepared by me in connection with my
employment.

                                     -11-
<PAGE>
 
     5.   I understand as part of the consideration for the offer of employment
extended to me by the Company and of my employment or continued employment by
the Company, that I have not brought and will not bring with me to the Company
or use in the performance of my responsibilities at the Company any materials or
documents of a former employer which are not generally available to the public,
unless I have obtained written authorization from the former employer for their
possession and use. I HAVE BROUGHT WITH ME MATERIALS AND DOCUMENTS OF PMI 
                    -----------------------------------------------------
RELATED TO DEVELOPMENTS TRANSFERRED OR LICENSED BY IT TO THE COMPANY.
- ---------------------------------------------------------------------

          Accordingly, this is to advise the Company that the only materials or
documents of a former employer which are not generally available to the public
that I have brought or will bring to the Company or have used or will use in my
employment are identified on Exhibit A attached hereto, and, as to each such
                             ---------                                      
item, I represent that I have obtained prior to the effective date of my
employment with the Company written authorization for their possession and use
in my employment with the Company.

     6.   During the course of my employment by the Company, I may learn of the
Company's confidential information or confidential information entrusted to the
Company by other persons, corporations, or firms. The Company's confidential
information includes matters not generally known outside the Company, such as
developments relating to existing and future products and services marketed or
used by the Company and data relating to the general business operations of the
Company (e.g., concerning sales, costs, profits, organizations, customer lists,
pricing methods, etc.). I agree not to disclose any confidential information of
the Company or of such other persons, corporations, or firms to others or to
make use of it, except on the Company's behalf, whether or not such information
is produced by my own efforts. Also, I may learn of developments, ways of
business, etc., which in themselves are generally known, but whose use by the
Company is not generally known, and I agree not to disclose to others such use,
whether or no such use is due to my own efforts.

     7.   At the time I begin my employment and during the term of my employment
by the Company, I will not become employed by or act on behalf of any other
person, corporation, or firm which is engaged in any business or activity
similar to or competitive with that of the Company, unless such employment has
been approved by the Company in writing and signed by an appropriate personnel
manager of the Company.

     8.   In the event that my employment is transferred by the Company to a
subsidiary or affiliated company (as the case may be), my employment by such
company will, for the purposes of this Agreement, be considered as continued
employment by the Company, unless I execute an agreement substantially similar
in substance to this Agreement, in which event my employment by the Company
shall be deemed to continue until the effective date of said agreement in any
such company for which I become employed.

     9.   I hereby give the Company and its assigns permission to reasonably use
photographs of me, either during or after my employment, with or without using
my name, for whatever purposes it deems necessary.

     10.  Upon termination of my employment, unless my employment is transferred
to a subsidiary or affiliated company of the Company, I agree to leave with the
Company all records, drawings, notebooks, and other documents pertaining to the
Company's confidential information,

                                     -12-
<PAGE>
 
whether prepared by me or others, and also any equipment, tools or other devices
owned by the Company, then in my possession however such items are obtained, and
I agree not to reproduce any document or data relating thereto.

     11.  My obligations under this Agreement shall survive the termination of
my employment regardless of the manner of such termination, and shall be binding
upon my heirs, executors, and administrators.

     12.  CONTEMPORANEOUSLY WITH entering the employ of the Company I have
          ----------------------                                     
terminated employment with all past employers.

     13.  As a matter of record I have identified on Exhibit B attached hereto
                                                     ---------         
all developments relevant to the subject matter of my employment by the Company
which have been made or conceived or first reduced to practice by me alone or
jointly with others prior to my engagement by the Company which I desire to
remove from the operation of this Agreement; and I covenant that such list is
complete. If there is no such list on Exhibit B, I represent that I have made no
                                      ---------                    
such developments at the time of signing this Agreement.

     14.  I agree that in addition to any other rights and remedies available to
the Company for any breach by me of my obligations hereunder, the Company shall
be entitled to enforcement of my obligations hereunder by court injunction.

     15.  If any provision of this Agreement shall be declared invalid, illegal
or unenforceable, then such provision shall be enforceable to the extent that a
court shall deem it reasonable to enforce such provision. If such provision
shall be unreasonable to any extent, such provision shall be severed from this
Agreement and all remaining provisions shall continue in full force and effect.

     16.  This Agreement shall be effective as of the date set forth below next
to my signature.

     17.  This Agreement shall be governed in all respects by the laws of the
Commonwealth of Massachusetts.

     IN WITNESS WHEREOF, I have executed this Agreement under seal as of the

                         Control;

               the Company shall pay the Executive a severance payment, equal to

                         prior to the Change in Control or a substantial adverse
                         alteration in the nature or status of his position or
                         responsibilities or the conditions of his employment
                         from those in effect immediately prior to the Change in
                         Control; (b) a reduction by the Company in the Base

                         except for required travel

<PAGE>
 
                         on the Company's business to an extent substantially
                         consistent with his present business travel
                         obligations; or (d) the failure by the Company to
                         continue in effect any material compensation or benefit
                         plan in which the Executive participates immediately
                         prior to the Change in Control unless an equitable
                         arrangement (embodied in an ongoing substitute or
                         alternative plan) has been made with respect to such
                         plan, or the failure by the Company to continue the
                         Executive's participation therein (or in such
                         substitute or alternative plan) on a basis not
                         materially less favorable, both in terms of the amount
                         of benefits provided and the level of his participation
                         relative to other participants, than existed at the
                         time of the Change in Control.

               3.3.2.3.  The Executive's continued employment shall not
                         constitute consent to, or a waiver of rights with
                         respect to any circumstance constituting Good Reason

                            AGREEMENT NOT TO COMPETE
                            ------------------------

I recognise that CardioTech International Inc., a Massachusetts corporation
having its principal place of business at 11 State Street, Woburn, MA 01801 (the
"Company" which term shall include its subsidiaries and affiliated entities)
desires to retain me in its employ and that the Company wishes to ensure that I
do not compete with the Company, as specified below, in the event my employment
with the Company is terminated.

In consideration of the Company's employment or continued employment of me, I
agree as follows:

1.   I will not, for a period of one (1) year commencing with the termination of
     my employment with the Company, engage (directly or indirectly) in any
     activities or render any services similar or reasonably related to these in
     which I shall be engaged or those reasonably related to those in which I
     shall have engaged or those which I shall have rendered as an employee of
     the Company during any part of the two year period preceding my termination
     for any trade or business which directly competes with the Company in any
     place where the Company does or may do business in any line of business
     engaged in (or planned to be engaged in) by the Company, where now existing
     or hereafter established, nor shall I engage in such activities nor render
     such services for any other person or entity engaged or about to become
     engaged in such activities to, for or on behalf of any such trade or
     business.

2.   I agree that for a period of one (1) year following termination of my
     employment with the Company, I will not solicit or in any manner encourage
     employees of the Company to leave their employ. I further agree that during
     such period I will not offer or cause to be offered employment to any
     person who was employed by the Company at any time during the six (6)
     months prior to the termination of my employment with the Company.

                                       12
<PAGE>
 
3.   For the purposes of this Agreement, "termination of employment" shall mean
     voluntary termination by me or termination by the Company for "Cause" (as
     that term is defined in a Service Agreement of even date herewith between
     me and CardioTech International Inc.).

4.   I understand that nothing in this Agreement shall affect my obligations
     under the "Confidential and Proprietary Information Agreement" between the
     Company and myself of even date herewith.

5.   I understand that in addition to any other rights and remedies available to
     the Company for any breach by me of my obligations hereunder, the Company
     shall be entitled to seek enforcement of my obligations hereunder by court
     injunction.

6.   If any provision of this Agreement shall be declared invalid, illegal or
     unenforceable by a court of competent jurisdiction in the United States,
     then such provision shall be enforceable to the extent that such court
     shall deem it reasonable to enforce such provision. If such provision shall
     be unreasonable to enforce to any extent, such provision shall be severed
     from this Agreement and all remaining provisions shall continue in full
     force and effect.

7.   This Agreement shall be governed in all respects by the Laws of the
     Commonwealth of Massachusetts.

IN WITNESS WHEREOF I have executed this Agreement.

              CONFIDENTIAL AND PROPRIETARY INFORMATION AGREEMENT
              --------------------------------------------------

In consideration of my employment by CardioTech International Inc. a
Massachusetts corporation having its principal place of business at 11 State
Street, Woburn, MA 01801 (the "Company"), which term shall include its
subsidiaries and affiliated entities), I hereby agree as follows:

1.   I will make full and prompt disclosure to the Company of all inventions,
     improvements, modification, discoveries, methods, data, ideas and
     developments (all of which are collectively termed "Developments"
     hereinafter), whether patentable or not, made or conceived or reduced to
     practice or learned by me either alone or jointly with others or under my
     direction during the period of my employment, whether or not made or
     conceived during normal working hours or on the premises of the Company. I
     do not have any Developments other than those I have already disclosed to
     the Company.

2.   I agree that all Developments covered by paragraph 1 shall be the sole
     property of the Company and its assigns, and the Company and its assigns
     shall be the sole owner of all patents and other rights in connection
     therewith. I hereby assign to the Company any rights in connection
     therewith. I hereby assign to the Company any rights I may have or acquire
     in all Developments.  I further agree as to all Developments to assist the
     Company in every proper way (but at the Company's expense) to obtain and
     from time to time enforce patents in Developments in any and all countries,
     and to that end I will execute all documents for use in applying for and
     obtaining such patents thereon and enforcing same as the Company may
     desire, together with any assignments thereof to the Company or persons
     designated by it.  My obligation to assist the Company in obtaining and
     enforcing patents for Developments in any and all countries shall continue
     beyond the termination of my employment, but the Company shall compensate
     me at a

                                       15
<PAGE>
 
     reasonable rate after such termination for time actually spent by me at the
     Company's request on such assistance.

     I understand that this paragraph 2 does not apply to Developments for which
     no equipment, supplies, facility or trade secret information of the Company
     was used and which were developed entirely on my own time, and (a) which do
     not relate (1) to the business of the Company or (2) to the Company's
     actual or demonstrable anticipated research or Development, and (b) which
     do not result from any work performed by me for the Company, but I agree
     that the Company shall have a non-exclusive royalty free license to use
     such Developments for all purposes.

3.   I hereby represent that, to the best of my knowledge, I have no present
     obligation to assign to any former employer or any other person,
     corporation or firm, any Development covered by paragraph 2. I represent
     that my performance of all the terms of this Agreement as an employee of
     the Company does not and will not breach any agreement to keep in
     confidence proprietary information acquired by me in confidence or in trust
     prior to my employment by the Company. I have no entered into, and I agree
     I will not enter into, any agreement (either written or oral) in conflict
     herewith.

4.   I will also assign to the Company and all copyrights and reproduction
     rights to any material prepared by me in connection with my employment.

5.   I understand as part of the consideration for the offer of employment
     extended to me by the Company and of my employment or continued employment
     by the Company that have not brought and will not bring with me to the
     Company or use in the performance of my responsibilities at the Company any
     materials or documents of a former employer which are not generally
     available to the public, unless I have obtained written authorisation from
     the former employer for their possession and use.

                                       16
<PAGE>
 
6.   During the course of my employment by the Company, I may learn of the
     Company's confidential information or confidential information entrusted to
     the Company by other persons, corporations, or firms. The Company's
     confidential information includes matters not generally known outside the
     Company, such as Developments relating to existing and future products and
     services marketed or used by the Company and data relating to the general
     business operations of the Company (e.g. concerning sales, costs, profits,
     organisations, customer lists, pricing methods etc.). I agree not to
     disclose any confidential information of the Company or of such other
     persons, corporations, or firms to others or to make use of it, except on
     the Company's behalf, whether or not such information is produced by my own
     efforts. Also, I may learn of Developments, ways of business, etc. which in
     themselves are generally known, but whose use by the Company is not
     generally known, and I agree not to disclose to other such use, whether or
     not such use is due to my own efforts.

                            AGREEMENT NOT TO COMPETE
                            ------------------------

I recognize that CardioTech International Ltd. a company incorporated under
English law (the "Company" which term shall include its subsidiaries and
affiliated entities) desires to retain me in its employ and that the Company
wishes to ensure that I do not compete with the Company, as specified below, in
the event my employment with the Company is terminated.

In consideration of the Company's employment or continued employment of me, I
agree as follows:

1.   I will not, for a period of one (1) year commencing with the termination of
     my employment with the Company, engage (directly or indirectly) in any
     activities or render any services similar or reasonably related to those in
     which I shall be engaged or those reasonably related to those in which I
     shall have engaged or those which I shall have rendered as an employee of
     the Company during any part of the two year period preceding my termination
     for any trade or business which directly competes with the Company in any
     place where the Company does or may do business in any line of business
     engaged in (or planned to be engaged in) by the Company, where now existing
     or hereafter established, nor shall I engage in such activities nor render
     such services for any other person or entity engaged or about to become
     engaged in such activities to, for or on behalf of any such trade or
     business.

2.   I agree that for a period of one (1) year following termination of my
     employment with the Company, I will not solicit or in any manner encourage
     employees of the Company to leave their employ. I further agree that during
     such period I will not offer or cause to be offered employment to any
     person who was employed by the Company at any time during the six (6)
     months prior to the termination of my employment with the Company.

                                       16
<PAGE>
 
3.   For the purposes of this Agreement. "termination of employment" shall mean
     voluntary termination by me or termination by the Company for "Cause" (as
     that term is defined in an Employment Agreement of even date herewith
     between me and the Company).

4.   I understand that nothing in this Agreement shall affect my obligations
     under the "Confidential and Proprietary Information Agreement" between the
     Company and myself of even date herewith.

5.   I understand that in addition to any other rights and remedies available to
     the Company for any breach by me of my obligations hereunder, the Company
     shall be entitled to seek enforcement of my obligations hereunder by court
     injunction.

6.   If any provision of this Agreement shall be declared invalid, illegal or
     unenforceable, then such provision shall be enforceable to the extent that
     a court shall deem it reasonable to enforce such provision. If such
     provision shall be unreasonable to enforce to any extent, such provision
     shall be severed from this Agreement and all remaining provisions shall
     continue in full force and effect.

7.  This Agreement shall be governed in all respects by the laws of England.

IN WITNESS WHEREOF I have executed this Agreement.

              CONFIDENTIAL AND PROPRIETARY INFORMATION AGREEMENT
               --------------------------------------------------

In consideration of my employment by CardioTech International, Ltd. a company
incorporated under English law (the "Company", which term shall include its
subsidiaries and affiliated entities), I hereby agree as follows:

1.   I will make full and prompt disclosure to the Company of all inventions,
     improvements, modification, discoveries, methods, data, ideas and
     developments (all of which are collectively -termed "Developments"
     hereinafter), whether patentable or not, made or conceived or reduced to
     practice or learned by me either alone or jointly with others or under my
     direction during the period of my employment, whether or not made or
     conceived during normal working hours or on the premises of the Company.  I
     do not have any Developments other than those I have already disclosed to
     the Company.

2.   I agree that all Developments covered by paragraph 1 shall be the sole
     property of the Company and its assigns, and the Company and its assigns
     shall be the sole owner of all patents and other rights in connection
     therewith. I hereby assign to the Company any rights in connection
     therewith. I hereby assign to the Company any rights I may have or acquire
     in all Developments. I further agree as to all Developments to assist the
     Company in every proper way (but at the Company's expense) to obtain and
     from time to time enforce patents in Developments in any and all countries,
     and to that end I will execute all documents for use in applying for and
     obtaining such patents thereon and enforcing same as the Company may
     desire, together with any assignments thereof to the Company or persons
     designated by it. My obligation to assist the Company in obtaining and
     enforcing patents for Developments in any and all countries shall continue
     beyond the termination of my employment, but the Company shall compensate
     me at a reasonable rate after such termination for time actually spent by
     me at the Company's request on such assistance.

                                       18
<PAGE>
 
     I understand that this paragraph 2 does not apply to Developments for which
     no equipment. supplies, facility or trade secret information of the Company
     was used and which were developed entirely on my own time, and (a) which do
     not relate (1) to the business of the Company or (2) to the Company's
     actual or demonstrable anticipated research or Development, and (b) which
     do not result from any work performed by me for the Company, but I agree
     that the Company shall have a non-exclusive royalty free license to use
     such Developments far all purposes.

3.   I hereby represent that, to the best or my knowledge, I have no present
     obligation to assign to any former employer or any other person,
     corporation or firm, any Development covered by paragraph 2.  I represent
     that my performance of all the terms of this Agreement as an employee of
     the Company does not and will not breach any agreement to keep in
     confidence proprietary information acquired by me in confidence or in trust
     prior to my employment by the Company. I have no entered into, and I agree
     I will not enter into, any agreement (either written or oral) in conflict
     herewith.

     rights to any material prepared by me in connection with my employment.

5.   I understand as part of the consideration for the offer or employment
     extended to me by the Company and of my employment or continued employment
     by the Company that I have not brought and will not bring with me to the
     Company or use in the performance of my responsibilities at the Company any
     materials or documents of a former employer which are not generally
     available to the public, unless I have obtained written authorization from
     the former employer for their possession and use.

6.   During the course of my employment by the Company, I may learn of the
     Company's confidential information or confidential information entrusted to
     the Company by other persons, corporations, or firms. The Company's
     confidential information includes matters 

                                       19
<PAGE>
 
     not generally known outside the Company, such as Developments relating to
     existing and future products and services marketed or used by the Company
     and data relating to the general business operations of the Company (e.g.
     concerning sales, costs, profits, organizations, customer lists, pricing
     methods etc.). I agree not to disclose any confidential information of the
     Company or of such other persons, corporations, or firms to others or to
     make use of it, except on the Company's behalf, whether or not such
     information is produced by my own efforts. Also, I may learn of
     Developments, ways of business, etc. which in themselves are generally
     known, but whose use by the Company is not generally known, and I agree not
     to disclose to other such use, whether or not such use is due to my own
     efforts.

7.   At the time I begin my employment and during the term of my employment by
     the Company, I will not become employed by or act on behalf of any other
     person, company, or firm which is engaged in any business or activity
     similar to or competitive with that of the Company, unless such employment
     has been approved by the Company in writing and signed by an appropriate
     personnel manager of the Company.

8.   In the event that my employment is transferred by the Company to a
     subsidiary or affiliated company (as the case may be), my employment by
     such company will, for the purposes of this Agreement, be considered as
     continued employment by the Company, unless I execute an agreement
     substantially similar in substance to this Agreement, in which event my
     employment by the Company shall be deemed to continue until the effective
     date of said agreement in any such company for which I become employed.

9.   I hereby give the Company and its assigns permission to reasonably use
     photographs of me, either during or after my employment, with or without
     using my name, for whatever purposes it deems necessary.

10.  Upon termination of my employment, unless my employment is transferred to a
     subsidiary or affiliated company of the Company, I agree to leave with the
     Company all

     Company's confidential information, whether prepared by me or others, and
     also any equipment, tools or other devices owned by the Company, then in my
     possession however such items are obtained, and I agree not to reproduce
     any document or data relating thereto.

11.  My obligations under this Agreement shall survive the termination of my
     employment regardless of the manner of such termination, and shall be
     binding upon my heirs, executors, and administrators.

12.  Contemporaneously with entering the employ of the Company I have terminated
     employment with all past employers.

13.  I represent that I have made no Developments relevant to the subject matter
     of my employment by the Company that have been made or conceived or first
     reduced to practice by me alone or jointly with others prior to my
     engagement by the Company.

14.  I agree that in addition to any other rights and remedies available to the
     Company for any breach by me of my obligations hereunder, the Company shall
     be entitled to seek enforcement of my obligations hereunder by court
     injunction.

15.  If any provision of this Agreement shall be declared invalid, illegal or
     unenforceable, then such provision shall be enforceable to the extent that
     a court shall deem it reasonable to enforce such provision. If such
     provision shall be unreasonable to any extent, such provision shall be
     severed from this Agreement and all remaining provisions shall continue in
     full force and effect.

16.  This Agreement shall be effective as of the date set forth below next to my
     signature.

17.  This Agreement shall be governed in all respects by the laws of England.

                     CUMMINGS PROPERTIES MANAGEMENT, INC.
                                 STANDARD FORM


                               COMMERCIAL LEASE                     598325-DJC-B

In consideration of the covenants herein contained, Cummings Properties
Management, Inc., hereinafter called LESSOR, does hereby lease to CardioTech
International, Inc. (a MA corp.), 11 State Street, Woburn, MA 01801 hereinafter
called LESSEE, the following described premises, hereinafter called the leased
premises: approximately 15,788 square feet at 78-E Olympia Avenue, Woburn, MA
01801.

TO HAVE AND HOLD the leased premises for a term of five (5) years commencing at
noon on September 1, 1998 and ending at noon on August 30, 2003 unless sooner
terminated as herein provided. LESSOR and LESSEE now covenant and agree that the
following terms and conditions shall govern this lease during the term hereof
and for such further time as LESSEE shall hold the leased premises.

     1.   RENT.  LESSEE shall pay to LESSOR base rent at the rate of one hundred
eighty eight thousand six hundred sixty six (188,666.00) U.S. dollars per year,
drawn on a U.S. bank, payable in advance in monthly installments of $15,722.16
on the first day in each calendar month in advance, the first monthly payment to
be made upon LESSEE's execution of this lease, including payment in advance of
appropriate fractions of a monthly payment for any portion of a month at the
commencement or end of said lease term. All payments shall be made to LESSOR or
agent at 200 West Cummings Park, Woburn, Massachusetts 01801, or at such other
place as LESSOR shall from time to time in writing designate. If the "Cost of
Living" has increased as shown by the Consumer Price Index (Boston,
Massachusetts, all items, all urban consumers), U.S. Bureau of Labor Statistics,
the amount of base rent due during each calendar year of this lease and any
extensions thereof shall be annually adjusted in proportion to any increase in
the Index. All such adjustments shall take place with the rent due on January 1
of each year during the lease term. The base month from which to determine the
amount of each increase in the Index shall be January 1998, which figure shall
be compared with the figure for November 1999, and each November thereafter to
determine the percentage increase (if any) in the base rent to be paid during
the following calendar year. In the event that the Consumer Price Index as
presently computed is discontinued as a measure of "Cost of Living" changes, any
adjustment shall then be made on the basis of a comparable index then in general
use.

     2.   SECURITY DEPOSIT.  LESSEE shall pay to LESSOR a security deposit in
the amount of thirty nine thousand six hundred (39,600.00) U.S. dollars upon the
execution of this lease by LESSEE, which shall be held as security for LESSEE's
performance as herein provided and refunded to LESSEE without interest at the
end of this lease, subject to LESSEE's satisfactory compliance with the
conditions hereof. LESSEE may not apply the security deposit to payment of the
last month's rent. In the event of any default or breach of this lease by
LESSEE, LESSOR may immediately apply the security deposit first to any
unamortized improvements completed for LESSEE's occupancy, then to offset any
outstanding invoice or other payment due to LESSOR, with the balance applied to
outstanding rent. If all or any portion of the security deposit is applied to
cure a default or breach during the term of the lease, LESSEE shall be
responsible for restoring said deposit forthwith, and failure to do so shall be
considered a substantial default under the lease. LESSEE's failure to remit the
full security deposit or any portion thereof when due shall also constitute a
substantial lease default. Until such time as LESSEE pays the security deposit
and first months rent, LESSOR may declare this lease null and void for failure
of consideration.

     3.   USE OF PREMISES.  LESSEE shall use the leased premises only for the
purpose of office and manufacturing space.

     4.   ADDITIONAL RENT.  LESSEE shall pay to LESSOR as additional rent its
proportionate share (14.34%) (based on square footage leased by LESSEE as
compared with the total leaseable square footage of the building of which the
leased premises are a part) of any increase in the real estate taxes levied
against the land and building of which the leased premises are a part
(hereinafter called the building), whether such increase is caused by an
increase in the tax rate, or the assessment on the property, or a change in the
method of determining real estate taxes. LESSEE shall make payment within thirty
(30) days of written notice from LESSOR that such increased taxes are payable,
and any additional rent shall be prorated should the lease terminate before the
end of any tax year. The base from which to determine the amount of any increase
in taxes shall be the rate and the assessment in effect as of July 1, 1997.
<PAGE>
 
     5.   UTILITIES.  LESSOR shall provide equipment per LESSOR's building
standard specifications to heat the leased premises in season and to cool all
office areas between May 1 and November 1. LESSEE shall pay all charges for
utilities used on the leased premises, including electricity, gas, oil, water
and sewer. LESSEE shall pay the utility provider or LESSOR, as applicable, for
all such utility charges as determined by separate meters serving the leased
premises and/or as a proportionate share of the utility charges for the building
if not separately metered. LESSEE shall also pay LESSOR a proportionate share of
any other fees and charges relating in any way to utility use at the building.
No plumbing, construction or electrical work of any type shall be done without
LESSOR's prior written approval and LESSEE obtaining the appropriate municipal
permit.

     6.   COMPLIANCE WITH LAWS.  LESSEE acknowledges that no trade, occupation,
activity or work shall be conducted in the leased premises or use made thereof
which may be unlawful, improper, noisy, offensive, or contrary to any applicable
statute, regulation, ordinance or bylaw. LESSEE shall keep all employees working
in the leased premises covered by Workers Compensation Insurance and shall
obtain any licenses and permits necessary for LESSEE's occupancy. LESSEE shall
be responsible for causing the leased premises and any alterations by LESSEE
which are allowed hereunder to be in full compliance with any applicable
statute, regulation, ordinance or bylaw.

     7.   FIRE, CASUALTY EMINENT DOMAIN.  Should a substantial portion of the
leased premises, or of the property of which they are a part, be substantially
damaged by fire or other casualty, or be taken by eminent domain, LESSOR may
elect to terminate this lease. When such fire, casualty, or taking renders the
leased premises substantially unsuitable for their intended use, a just and
proportionate abatement of rent shall be made, and LESSEE may elect to terminate
this lease if: (a) LESSOR fails to give written notice within thirty (30) days
of intention to restore the leased premises, or (b) LESSOR fails to restore the
leased premises to a condition substantially suitable for their intended use
within ninety (90) days of said fire, casualty or taking. LESSOR reserves all
rights for damages or injury to the leased premises for any taking by eminent
domain, except for damage to LESSEE's property or equipment.

     8.   FIRE INSURANCE.  LESSEE shall not permit any use of the leased
premises which will adversely affect or make voidable any insurance on the
property of which the leased premises are a part, or on the contents of said
property, or which shall be contrary to any law or regulation from time to time
established by the Insurance Services Office (or successor), local Fire
Department, LESSOR's insurer, or any similar body. LESSEE shall on demand
reimburse LESSOR, and all other tenants, all extra insurance premiums caused by
LESSEE's use of the leased premises. LESSEE shall not vacate the leased premises
or permit same to be unoccupied other than during LESSEE's customary non-
business days or hours.

     9.   MAINTENANCE OF PREMISES.  LESSOR will be responsible for all
structural maintenance of the leased premises and for the normal daytime
maintenance of all space heating and cooling equipment, sprinklers, doors,
locks, plumbing, and electrical wiring, but specifically excluding damage caused
by the careless, malicious, willful, or negligent acts of LESSEE or others,
chemical, water or corrosion damage from any source, and maintenance of any non
"building standard" leasehold improvements. LESSEE agrees to maintain at its
expense all other aspects of the leased premises in the same condition as they
are at the commencement of the term or as they may be put in during the term of
this lease, normal wear and tear and damage by fire or other casualty only
excepted, and whenever necessary, to replace light bulbs, plate glass and other
glass therein, acknowledging that the leased premises are now in good order and
the light bulbs and glass whole. LESSEE will properly control or vent all
solvents, degreasers, smoke, odors, etc. and shall not cause the area
surrounding the leased premises to be in anything other than a neat and clean
condition, depositing all waste in appropriate receptacles. LESSEE shall be
solely responsible for any damage to plumbing equipment, sanitary lines, or any
other portion of the building which results from the discharge or use of any
acid or corrosive substance by LESSEE. LESSEE shall not permit the leased
premises to be overloaded, damaged, stripped or defaced, nor suffer any waste,
and will not keep animals within the leased premises. If the leased premises
include any wooden mezzanine type space, the floor capacity of such space is
suitable only for office use, light storage or assembly work. LESSEE will
protect any carpet with plastic or masonite chair pads under any rolling chairs.
Unless heat is provided at LESSORS expense, LESSEE shall maintain sufficient
heat to prevent freezing of pipes or other damage. Any increase in air
conditioning equipment or electrical capacity or any installation or maintenance
of equipment which is necessitated by some specific aspect of LESSEE's use of
the leased premises shall be LESSEE's sole responsibility, at LESSEE's expense
and subject to LESSOR's prior written consent. All maintenance provided by
LESSOR shall be during LESSOR's normal business hours.

     10.  ALTERATIONS.  LESSEE shall not make structural alterations or
additions of any kind to the leased premises, but may make nonstructural
alterations provided LESSOR consents thereto in writing. All such allowed
alterations shall be at LESSEE's expense and shall conform with LESSOR's
construction specifications. If LESSOR or LESSOR's agent provides any services
or maintenance for LESSEE in connection with such alterations or otherwise under
this lease, any just invoice will be promptly paid. LESSEE shall not permit any
mechanics' liens, or similar liens, to remain upon the leased premises in
connection with work of any

                                       2
<PAGE>
 
character performed or claimed to have been performed at the direction of LESSEE
and shall cause any such lien to be released or removed forthwith without cost
to LESSOR. Any alterations or additions shall become part of the leased premises
and the property of LESSOR. Any alterations completed by LESSOR or LESSEE shall
be LESSOR's "building standard" unless noted otherwise. LESSOR shall have the
right at any time to change the arrangement of parking areas, stairs, walkways
or other common areas of the building.

     11.  ASSIGNMENT OR SUBLEASING.  LESSEE shall not assign this lease or
sublet or allow any other firm or individual to occupy the whole or any part of
the leased premises without LESSOR's prior written consent. Notwithstanding such
assignment or subleasing, LESSEE and GUARANTOR shall remain liable to LESSOR for
the payment of all rent and for the full performance of the covenants and
conditions of this lease. LESSEE shall pay LESSOR promptly for legal and
administrative expenses incurred by LESSOR in connection with any consent
requested hereunder by LESSEE.

     12.  SUBORDINATION.  This lease shall be subject and subordinate to any and
all mortgages and other instruments in the nature of a mortgage, now or at any
time hereafter, and LESSEE shall, when requested, promptly execute and deliver
such written instruments as shall be necessary to show the subordination of this
lease to said mortgages or other such instruments in the nature of a mortgage.

     13.  LESSOR'S ACCESS.  LESSOR or agents of LESSOR may at any reasonable
time enter to view the leased premises, to make repairs and alterations as
LESSOR should elect to do for the leased premises, the common areas or any other
portions of the building, to make repairs which LESSEE is required but has
failed to do, and to show the leased premises to others.

     14.  SNOW REMOVAL.  The plowing of snow from all roadways and unobstructed
parking areas shall be at the sole expense of LESSOR. The control of snow and
ice on all walkways, steps and loading areas serving the leased premises and all
other areas not readily accessible to plows shall be the sole responsibility of
LESSEE. Notwithstanding the foregoing, however, LESSEE shall hold LESSOR and
OWNER harmless from any and all claims by LESSEE's agents, representatives,
employees, callers or invitees for damage or personal injury resulting in any
way from snow or ice on any area serving the leased premises, except for claims
arising out of LESSOR's negligence.

     15.  ACCESS AND PARKING.  LESSEE shall have the right without additional
charge to use parking facilities provided for the leased premises in common with
others entitled to the use thereof. Said parking areas plus any stairs,
corridors, walkways, elevators or other common areas (hereinafter collectively
called the common areas) shall in all cases be considered a part of the leased
premises when they are used by LESSEE or LESSEE's employees, agents, callers or
invitees. LESSEE will not obstruct in any manner any portion of the building or
the walkways or approaches to the building, and will conform to all rules and
regulations now or hereafter made by LESSOR for parking, and for the care, use,
or alteration of the building, its facilities and approaches. LESSEE further
warrants that LESSEE will not permit any employee or visitor to violate this or
any other covenant or obligation of LESSEE. No unattended parking will be
permitted between 7:00 PM and 7:00 AM without LESSOR's prior written approval,
and from December 1 through March 31 annually, such parking shall be permitted
only in those areas specifically designated for assigned overnight parking.
Unregistered or disabled vehicles, or storage trailers of any type, may not be
parked at any time. LESSOR may tow, at LESSEE's sole risk and expense, any
misparked vehicle belonging to LESSEE or LESSEE's agents, employees, invitees or
callers, at any time. LESSOR shall not be responsible for providing any security
services for the leased premises.

     16.  LIABILITY.  LESSEE shall be solely responsible as between LESSOR and
LESSEE for deaths or personal injuries to all persons whomsoever occurring in or
on the leased premises (including any common areas that are considered part of
the leased premises hereunder) from whatever cause arising, and damage to
property to whomsoever belonging arising out of the use, control, condition or
occupation of the leased premises by LESSEE; and LESSEE agrees to indemnify and
save harmless LESSOR and OWNER from any and all liability, including but not
limited to costs, expenses, damages, causes of action, claims, judgments and
attorneys fees caused by or in any way growing out of any matters aforesaid,
except for death, personal injuries or property damage directly resulting from
the negligence or willful misconduct of LESSOR.

     17.  INSURANCE.  LESSEE will secure and carry at its own expense a
commercial general liability policy insuring LESSEE, LESSOR and OWNER against
any claims based on bodily injury (including death) or property damage arising
out of the condition of the leased premises (including any common areas that are
considered part of the leased premises hereunder) or their use by LESSEE, such
policy to insure LESSEE, LESSOR and OWNER against any claim up to One Million
(1,000,000) Dollars in the case of any one accident involving bodily injury
(including death), and up to One Million (1,000,000) Dollars against any claim
for damage to property. LESSOR and OWNER shall be included in each such policy
as additional insureds using ISO Form CG 20 26 11 85 or some other form approved
by LESSOR. LESSEE will file with LESSOR prior to occupancy certificates and any
applicable

                                       3
<PAGE>
 
riders or endorsements showing that such insurance is in force, and thereafter
will file renewal certificates prior to the expiration of any such policies. All
such insurance certificates shall provide that such policies shall not be
cancelled without at least ten (10) days prior written notice to each insured.
In the event LESSEE shall fail to provide or maintain such insurance at any time
during the term of this lease, then LESSOR may elect to contract for such
insurance at LESSEE's expense.

     18.  SIGNS.  LESSOR authorizes, and LESSEE at LESSEE's expense agrees to
erect promptly upon commencement of this lease, signage for the leased premises
in accordance with LESSOR's building standards for style, size, location, etc.
LESSEE shall obtain the prior written consent of LESSOR before erecting any sign
on the leased premises, which consent shall include approval as to size,
wording, design and location. LESSOR may remove and dispose of any sign not
approved, erected or displayed in conformance with this lease.

     19.  BROKERAGE.  LESSEE warrants and represents to LESSOR that LESSEE has
dealt with no broker except Mark St. Jean of Phoenix Corporate Services or third
person with respect to this lease, and LESSEE agrees to indemnity LESSOR against
any brokerage claims arising by virtue of this lease. LESSOR warrants and
represents to LESSEE that LESSOR has employed no exclusive broker or agent in
connection with the letting of the leased premises.

     20.  DEFAULT AND ACCELERATION OF RENT.  In the event that: (a) any
assignment for the benefit of creditors, trust mortgage, receivership or other
insolvency proceeding shall be made or instituted with respect to LESSEE or
LESSEE's property; (b) LESSEE shall default in the observance or performance of
any of LESSEE's covenants, agreements, or obligations hereunder, other than
substantial monetary payments as provided below, and such default shall not be
corrected within twenty (20) days after written notice thereof; or (c) LESSEE
vacates the leased premises without continuing to pay rent, then LESSOR shall
have the right thereafter, while such default continues and without demand or
further notice, to re-enter and take possession of the leased premises, to
declare the term of this lease ended, and to remove LESSEE's effects, without
being guilty of any manner of trespass, and without prejudice to any remedies
which might be otherwise used for arrears of rent or other default or breach of
the lease. If LESSEE shall default in the payment of the security deposit, rent,
taxes, substantial invoice from LESSOR or LESSOR's agent for goods and/or
services or other sum herein specified, and such default shall continue for ten
(10) days after written notice thereof, and, because both parties agree that
nonpayment of said sums when due is a substantial breach of the lease, and,
because the payment of rent in monthly installments is for the sole benefit and
convenience of LESSEE, then in addition to the foregoing remedies the entire
balance of rent which is due hereunder shall become immediately due and payable
as liquidated damages. LESSOR, without being under any obligation to do so and
without thereby waiving any default, may remedy same for the account and at the
expense of LESSEE. If LESSOR pays or incurs any obligations for the payment of
money in connection therewith, such sums paid or obligations incurred plus
interest and costs, shall be paid to LESSOR by LESSEE as additional rent. Any
sums received by LESSOR from or on behalf of LESSEE at any time shall be applied
first to any unamortized improvements completed for LESSEE's occupancy, then to
offset any outstanding invoice or other payment due to LESSOR, with the balance
applied to outstanding rent. LESSEE agrees to pay reasonable attorney's fees
and/or administrative costs incurred by LESSOR in enforcing any or all
obligations of LESSEE under this lease at any time. LESSEE shall pay LESSOR
interest at the rate of eighteen (18) percent per annum on any payment from
LESSEE to LESSOR which is past due.

     21.  NOTICE.  Any notice from LESSOR to LESSEE relating to the leased
premises or to the occupancy thereof shall be deemed duly served when served by
constable, or sent to the leased premises by certified mail, return receipt
requested, postage prepaid, addressed to LESSEE. Any notice from LESSEE to
LESSOR relating to the leased premises or to the occupancy thereof shall be
deemed duly served when served by constable, or delivered to LESSOR by certified
mail, return receipt requested, postage prepaid, addressed to LESSOR at 200 West
Cummings Park, Woburn, MA 01801 or at LESSOR's last designated address. No oral
notice or representation shall have any force or effect. Time is of the essence
in the service of any notice.

     22.  OCCUPANCY.  In the event that LESSEE takes possession of said leased
premises prior to the start of the lease term, LESSEE will perform and observe
all of LESSEE's covenants from the date upon which LESSEE takes possession
except the obligation for the payment of extra rent for any period of less than
one month. LESSEE shall not remove LESSEE's goods or property from the leased
premises other than in the ordinary and usual course of business, without having
first paid and satisfied LESSOR for all rent which may become due during the
entire term of this lease. In the event that LESSEE continues to occupy or
control all or any part of the leased premises after the agreed termination of
this lease without the written permission of LESSOR, then LESSEE shall be liable
to LESSOR for any and all loss, damages or expenses incurred by LESSOR, and all
other terms of this lease shall continue to apply except that rent shall be due
in full monthly installments at a rate of one hundred fifty (150) percent of
that which would otherwise be due under this lease, it being understood between
the parties that such extended occupancy is as a tenant at sufferance and is
solely for the benefit and convenience of LESSEE and as such has greater rental
value. LESSEE's control or occupancy of all or any part of the leased premises
beyond noon on the last day of any monthly rental period shall constitute

                                       4
<PAGE>
 
LESSEE's occupancy for an entire additional month, and increased rent as
provided in this section shall be due and payable immediately in advance.
LESSOR's acceptance of any payments from LESSEE during such extended occupancy
shall not alter LESSEE's status as a tenant at sufferance.

     23.  FIRE PREVENTION.  LESSEE agrees to use every reasonable precaution
against fire and agrees to provide and maintain approved, labeled fire
extinguishers, emergency lighting equipment, and exit signs and complete any
other modifications within the leased premises as required or recommended by the
Insurance Services Office (or successor organization), OSHA, the local Fire
Department, or any similar body.

     24.  OUTSIDE AREA.  Any goods, equipment, or things of any type or
description held or stored in any common area without LESSOR's prior written
consent shall be deemed abandoned and may be removed by LESSOR at LESSEE's
expense without notice. LESSEE shall maintain a building standard size dumpster
in a location approved by LESSOR, which dumpster shall be provided and serviced
at LESSEE's expense by whichever disposal firm may from time to time be
designated by LESSOR.

     25.  ENVIRONMENT.  LESSEE will so conduct and operate the leased premises
as not to interfere in any way with the use and enjoyment of other portions of
the same or neighboring buildings by others by reason of odors, smoke, exhaust,
smells, noise, pets, accumulation of garbage or trash, vermin or other pests, or
otherwise, and will at its expense employ a professional pest control service if
necessary. LESSEE agrees to maintain efficient and effective devices for
preventing damage to heating equipment from solvents, degreasers, cutting oils,
propellants, etc. which may be present at the leased premises. No hazardous
materials or wastes shall be stored, disposed of, or allowed to remain at the
leased premises at any time, and LESSEE shall be solely responsible for any and
all corrosion or other damage associated with the use, storage and/or disposal
of same by LESSEE.

     26.  RESPONSIBILITY.  Neither LESSOR nor OWNER shall be held liable to
anyone for loss or damage caused in any way by the use, leakage, seepage or
escape of water from any source, or for the cessation of any service rendered
customarily to said premises or buildings, or agreed to by the terms of this
lease, due to any accident, the making of repairs, alterations or improvements,
labor difficulties, weather conditions, mechanical breakdowns, trouble or
scarcity in obtaining fuel, electricity, service or supplies from the sources
from which they are usually obtained for said building, or any cause beyond
LESSOR's immediate control.

     27.  SURRENDER.  LESSEE shall at the termination of this lease remove all
of LESSEE's goods and effects from the leased premises. LESSEE shall deliver to
LESSOR the leased premises and all keys and locks thereto, all fixtures and
equipment connected therewith, and all alterations, additions and improvements
made to or upon the leased premises, whether completed by LESSEE, LESSOR or
others, including but not limited to any offices, partitions, window blinds,
floor coverings (including computer floors), plumbing and plumbing fixtures, air
conditioning equipment and ductwork of any type, exhaust fans or heaters, water
coolers, burglar alarms, telephone wiring, telephone equipment, air or gas
distribution piping, compressors, overhead cranes, hoists, trolleys or
conveyors, counters, shelving or signs attached to walls or floors, all
electrical work, including but not limited to lighting fixtures of any type,
wiring, conduit, EMT, transformers, distribution panels, bus ducts, raceways,
outlets and disconnects, and furnishings or equipment which have been bolted,
welded, nailed, screwed, glued or otherwise attached to any wall, floor,
ceiling, root pavement or ground, or which have been directly wired to any
portion of the electrical system or which have been plumbed to the water supply,
drainage or venting systems serving the leased premises. LESSEE shall deliver
the leased premises sanitized from any chemicals or other contaminants, and
broom clean and in the same condition as they were at the commencement of this
lease or any prior lease between the parties for the leased premises, or as they
were modified during said term with LESSOR's written consent, reasonable wear
and tear and damage by fire or other casualty only excepted. In the event of
LESSEE's failure to remove any of LESSEE's property from the leased premises
upon termination of the lease, LESSOR is hereby authorized, without liability to
LESSEE for loss or damage thereto, and at the sole risk of LESSEE, to remove and
store any such property at LESSEE's expense, or to retain same under LESSOR's
control, or to sell at public or private sale (without notice), any or all of
the property not so removed and to apply the net proceeds of such sale to the
payment of any sum due hereunder, or to destroy such abandoned property. In no
case shall the leased premises be deemed surrendered to LESSOR until the
termination date provided herein or such other date as may be specified in a
written agreement between the parties, notwithstanding the delivery of any keys
to LESSOR.

     28.  GENERAL.  (a) The invalidity or unenforceability of any provision of
this lease shall not affect or render invalid or unenforceable any other
provision hereof. (b) The obligations of this lease shall run with the land, and
this lease shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that LESSOR and OWNER shall
be liable only for obligations occurring while lessor, owner, or master lessee
of the premises. (c) Any action or proceeding arising out of the subject matter
of this lease shall be brought by LESSEE within one year after the cause of
action has occurred and only in a court of the Commonwealth of Massachusetts.
(d) If LESSOR is acting under or as agent for any trust or corporation, the
obligations

                                       5
<PAGE>
 
of LESSOR shall be binding upon the trust or corporation, but not upon any
trustee, officer, director, shareholder, or beneficiary of the trust or
corporation individually. (e) If LESSOR is not the owner (OWNER) of the leased
premises, LESSOR represents that said OWNER has agreed to be bound by the terms
of this lease unless LESSEE is in default hereof. (f) This lease is made and
delivered in the Commonwealth of Massachusetts, and shall be interpreted,
construed, and enforced in accordance with the laws thereof. (g) This lease was
the result of negotiations between parties of equal bargaining strength, and
when executed by both parties shall constitute the entire agreement between the
parties, superseding all prior oral and written agreements, representations,
statements and negotiations relating in any way to the subject matter herein.
This lease may not be extended or amended except by written agreement signed by
both parties or as otherwise provided herein, and no other subsequent oral or
written representation shall have any effect hereon. (h) Notwithstanding any
other statements herein, LESSOR makes no warranty, express or implied,
concerning the suitability of the leased premises for LESSEE's intended use. (i)
LESSEE agrees that if LESSOR does not deliver possession of the leased premises
as herein provided for any reason, LESSOR shall not be liable for any damages to
LESSEE for such failure, but LESSOR agrees to use reasonable efforts to deliver
possession to LESSEE at the earliest possible date. A proportionate abatement of
rent, excluding the cost of any amortized improvements to the leased premises,
for such time as LESSEE may be deprived of possession of the leased premises,
except where a delay in delivery is caused in any way by LESSEE, shall be
LESSEE's sole remedy. (j) Neither the submission of this lease form, nor the
prospective acceptance of the security deposit and/or rent shall constitute a
reservation of or option for the leased premises, or an offer to lease, it being
expressly understood and agreed that this lease shall not bind either party in
any manner whatsoever until it has been executed by both parties. (k) LESSEE
shall not be entitled to exercise any option contained herein if LESSEE is at
that time in default of any terms or conditions hereof. (l) Except as otherwise
provided herein, LESSOR, OWNER and LESSEE shall not be liable for any special,
incidental, indirect or consequential damages, including but not limited to lost
profits or loss of business, arising out of or in any manner connected with
performance or nonperformance under this lease, even if any party has knowledge
of the possibility of such damages. (m) The headings in this lease are for
convenience only and shall not be considered part of the terms hereof. (n) No
endorsement by LESSEE on any check shall bind LESSOR in any way. (o) LESSOR and
LESSEE hereby waive any and all rights to a jury trial in any proceeding in any
way arising out of this lease.

     29.  This paragraph has been deleted as it does not apply.

     30.  WAIVERS, ETC.  No consent or waiver express or implied by LESSOR to or
of any breach of any covenant, condition or duty of LESSEE shall be construed as
a consent or waiver to or of any other breach of the same or any other covenant,
condition or duty. If LESSEE is several persons, several corporations or a
partnership, LESSEE's obligations are joint or partnership and also several.

                                RIDER TO LEASE                      598325-DJC-5

The following additional provisions are incorporated into and made a part of the
attached lease:

A.   LESSOR, at LESSOR's cost, shall modify the leased premises according to a
     mutually agreed upon plan attached hereto before LESSEE takes possession of
     the leased premises, except for punch list items which shall be completed
     within 30 days following LESSEE's occupancy.

B.   * LESSOR, if requested to do so by LESSEE, and at LESSEE's sole expense,
     agrees to complete certain improvements and alterations necessitated by
     LESSEE's use of the leased premises according to a plan to be mutually
     agreed upon by both parties. These alterations shall be considered
     "nonbuilding standard" for maintenance purposes pursuant to Section 9 of
     the lease.

C.   The parties acknowledge and agree that, as of the execution of this lease,
     the leased premises have not been demised. Accordingly, upon completion of
     the modifications provided for herein, LESSOR shall measure the leased
     premises, and if the size does not equal the total number of square feet
     set forth in the initial paragraph of this lease, the parties shall execute
     an amendment to this lease that adjusts the size and rent accordingly. The
     total square footage of the leased premises shall not exceed 20,000
     leaseable square feet in the event the size of the leased premises does
     change.

D.   * Notwithstanding monthly rent as provided in Section 1 above, LESSEE may
     deduct $1,315.66 per month from each monthly rental payment due from
     September 1,1998 through August 30, 1999 (only), provided LESSOR receives
     each such monthly payment on or before the first day of the month for which
     that rent is due and LESSEE is not otherwise in default of the lease or in
     arrears of any rent or invoice payments. Time is of the essence.

E.   * The maximum cumulative "Cost of Living" increase during the initial term
     of the lease (only) shall not exceed an average of 8% per calendar year.

F.   * Whenever LESSOR's or LESSEE's consent, agreement or approval is required
     under this lease, said consent, agreement or approval shall not be
     unreasonably withheld or delayed.

G.   * LESSEE shall have the right to assign this lease or sublet the leased
     premises to an affiliated corporation, namely a corporation in which LESSEE
     owns at least a 50 percent interest, a corporation which owns at least a 50
     percent interest in LESSEE, a corporation which is under common control
     with LESSEE, a corporation with which LESSEE merges, or a corporation which
     is formed as a result of a merger or consolidation involving LESSEE,
     without further consent from LESSOR, provided LESSEE serves LESSOR with
     prior written notice to that effect. The provisions of Section 11 shall
     govern said assignment in all other respects.

H.   * LESSOR agrees that all work to be performed by LESSOR as set forth in the
     plan attached hereto shall be completed in a good and workmanlike manner.

I.   * Notwithstanding the commencement date of the lease, LESSEE may occupy the
     leased premises as of August 15, 1998, or as soon as substantially
     complete, provided this lease has been fully executed, the Security Deposit
     and the first month's rent due for the month of September 1998 have been
     fully paid, and all required insurance certificates and financing
     statements have been produced, without further obligation for the payment
     of monthly rent until October 1, 1998. All other terms, covenants and
     conditions of this lease shall apply during this rent-free period.
<PAGE>
 
J.   * LESSEE shall have access to the leased premises seven days per week, 24
     hours per day. LESSEE acknowledges and agrees that LESSOR has no
     responsibility for providing any security services for the leased premises,
     and LESSEE assumes any and all risks in that regard.

K.   * LESSOR and LESSEE do hereby mutually release and discharge each other of
     and from all liability and responsibility to the other for any loss, damage
     or liability covered by insurance if and to the extent that the written
     release and, discharge does not invalidate or adversely affect any
     applicable insurance, provided both parties secure and maintain all
     insurance required hereunder.

L.   During the initial term of this lease, LESSEE shall have the option to
     lease approximately 6,100 square feet of additional mezzanine level space
     above the leased premises under proportionately the same terms and
     conditions as this lease, provided said space is then available for lease
     directly from LESSOR, by serving LESSOR with written notice of its desire
     to lease said space. Upon receipt of LESSEE's notice, LESSOR shall deliver
     to LESSEE an amendment to this lease which incorporates said space into the
     leased premises, and LESSEE must then sign and deliver to LESSOR said
     amendment within three business days of receipt. LESSOR shall then have two
     months from receipt of the signed amendment to deliver said space. If said
     space is then under lease to another party, during the two-month delivery
     period LESSOR shall either (1) relocate the other party or (2) deliver a
     similar amount of additional space elsewhere in one of LESSOR's buildings
     on proportionately the same terms and conditions, except that the rental
     rate shall be one-half its then current rental rate for the first floor
     premises. This election of remedies shall be LESSEE's exclusive remedy for
     any failure by LESSOR to deliver possession of said mezzanine level space
     or any breach by LESSOR of the provisions of this paragraph. Time is of the
     essence.

                                       10
<PAGE>
 
          9.1.2.  The Parent shall procure that subject to Clause 9.1.4 below,
                  on the second anniversary of the Effective Date (or, if not
                  possible, the first day immediately following the date on
                  which such securities may be registered with the SEC) those
                  Option Shares then issued to (which shall for the avoidance of
                  doubt include any Option Shares issued on such date), and not
                  previously disposed of by Freemedic shall be registered with
                  the SEC under the Securities Act. Registration shall be made
                  at the cost and expense of the Parent by filing a registration
                  statement with the SEC, no later than 30 days prior to the
                  second anniversary of the Effective Date and using its best
                  efforts to cause such registration statement to be declared
                  effective by the SEC prior to the second anniversary of the
                  Effective Date. The Parent shall keep such registration
                  statement continuously effective for the lesser of 45 days or
                  the period required for Freemedic to distribute the Option
                  Shares registered pursuant thereto. Notwithstanding the
                  foregoing, the Parent may delay filing a registration
                  statement and may withhold efforts to cause the registration
                  statement to become effective if the Parent shall furnish to
                  Freemedic a certificate signed by the President of the Parent
                  stating that in the good faith judgment of its Board of
                  Directors (i) such registration would have a material adverse
                  effect on the Parent's ability to negotiate or complete a
                  transaction which had been approved by the Board of Directors
                  prior to the date on which the Parent filed or was to have
                  filed the registration statement as set forth above or (ii) it
                  would be seriously detrimental to the Parent and its
                  stockholders for such registration statement to be filed
                  within such period. If, after a registration statement becomes
                  effective, the Parent advises Freemedic that the Parent
                  considers it appropriate for the registration statement to be
                  amended, Freemedic shall suspend any further sales of its
                  registered shares until the Parent advises it that the
                  registration statement has been amended. The number of days
                  during which the registration statement shall be effective
                  shall be extended for an additional number of days equal to
                  the number of

                                      11
<PAGE>
 
                  days during which Freemedics' right to sell the Option Shares
                  was suspended pursuant to the preceding sentence.

          9.1.3.  For the avoidance of doubt, any disposal of Option Shares
                  shall be subject to the provisions of this Agreement and in
                  particular this Clause 9.

          9.1.4.

                  (a)  The Parent shall further procure that if prior to the
                       expiry of the period mentioned in Clause 9.1.2 above the
                       Parent shall register (other than a registration relating
                       solely to employee benefit plans or a Rule 145
                       transaction or a registration on any registration form
                       that does not permit secondary resales) any other
                       unregistered Common Stock (not being Option Shares) with
                       the SEC, (including pursuant to a demand ("demand") of
                       any stockholder of the Parent exercising registration
                       rights), it shall (i) promptly give Freemedic notice
                       thereof, and (ii) at its own cost and expense, include in
                       such registration and in any underwriting involved
                       therein, subject to paragraphs (b) and (c) below, all or
                       any part of the Option Shares that have been purchased
                       hereunder that are specified in written notice from
                       Freemedic that is received by the Parent within twenty
                       days after the written notice from the Parent described
                       above is mailed or delivered by the Parent.

                  (b)  If the registration of which the Parent gives notice is
                       for a registered public offering involving an
                       underwriting, the right to registration hereunder shall
                       be conditioned upon Freemedic's participation in such
                       underwriting, the inclusion of Freemedic's Option Shares
                       in the underwriting to the extent provided herein and
                       Freemedic entering into an underwriting agreement in
                       customary form with the representative of the underwriter
                       selected by the Parent. Freemedic shall not be required
                       to make any 

                                       12
<PAGE>
 
                       representations or warranties to or agreements with the
                       Parent or the underwriters other than representations and
                       warranties contained in a writing furnished by Freemedic
                       expressly for use in such registration statement or
                       representations, warranties and agreements regarding
                       Freemedic, the Option Shares being registered and
                       Freemedic's intended method of distribution and any other
                       representation required by law. If the representative of
                       the underwriters advises the Parent in writing that
                       marketing factors require a limitation on the number of
                       shares to be underwritten, the representative may
                       (subject to the limitations set forth below) exclude the
                       Option Shares from, or limit the number of Option Shares
                       to be included in, the registration and underwriting. The
                       Parent shall so advise all holders of securities
                       requesting registration pursuant to contractual,
                       incidental ("piggy back") registration rights, and the
                       number of shares of securities that are entitled to be
                       included in the registration and underwriting shall be
                       allocated first to the Parent (or, if applicable to the
                       stockholders exercising demand registration rights) for
                       securities being sold for its own account and thereafter
                       as set forth in paragraph (c) below.

                  (c)  In any circumstance in which all of the Option Shares and
                       other shares of Common Stock with piggy back registration
                       rights (including any security convertible into Common
                       Stock) ("Other Shares") requested to be included in a
                       registration cannot be so included, the number of shares
                       of Option Shares and Other Shares that may be so included
                       shall be allocated among Freemedic and the other selling
                       stockholders requesting inclusion of shares such that the
                       selling holders of the Option Shares and Other Shares
                       shall have their shares included pro rata on the basis of
                       the number of 

                                       13
<PAGE>
 
                       shares of Option Shares and Other Shares that would be
                       held by Freemedic and the other selling stockholders
                       assuming conversion that Freemedic and the other selling
                       stock holders had requested to be included in the
                       registration, provided that Freemedic shall have priority
                       to all shares sought to be included by officers and
                       directors of the Parent. The Parent shall have the right
                       to postpone or withdraw any registration effected without
                       obligation to Freemedic.

          9.1.5.

                  (a)  In connection with any registration, Freemedic will pay
                       its own costs and expenses, including the fees of its
                       counsel and brokerage fees and commissions and transfer
                       taxes on resale of any Option Shares. As soon as
                       practicable but in no event later than the third business
                       day following receipt of a written request from the
                       Parent, Freemedic shall furnish the Parent with such
                       information regarding Freemedic and its proposed
                       dispositions of Option Shares as the Parent may from time
                       to time reasonably request for use in preparing any
                       registration statement hereunder (and any related
                       qualification under applicable state securities laws).
                       The Parent shall not be obligated to register the Option
                       Shares if Freemedic fails to promptly provide the Parent
                       with such information as the parent may reasonably
                       request at the time to enable the Parent to comply with
                       applicable laws or regulations to facilitate the
                       preparation of the registration statement (and any
                       related qualification under applicable state securities
                       laws). Freemedic shall notify the Parent within five
                       business days of completion of its disposition of the
                       Option Shares.

                  (b)  In the case of each registration effected by the Parent
                       pursuant to this Agreement, at its expense the Parent
                       will:

                       (i)    promptly prepare and file with the SEC the
                              registration statement to effect such registration
                              and such amendments and supplements to such
                              registration statement and the prospectus used in
                              connection therewith as may be necessary to comply
                              with the provisions of the Securities Act and to
                              keep such registration statement effective for
                              that period of time specified in Clause 9.1.2,
                              provided that before filing such registration
                              statement or any amendments thereto, the Parent
                              will furnish to Freemedic and its counsel copies
                              of all documents proposed to be filed;

                              time to time may reasonably request;

                       (iii)  use its best efforts to register or qualify the
                              Option Shares covered by such registration

                              reasonably requires (other than any state in which
                              the Parent would be required to execute a general
                              consent to service of process in effecting such
                              registration), and keep such registration or
                              qualification effective during the period set
                              forth in Clause 9.1.2;

                       (iv)   cause its accountants to issue to Freemedic and
                              any underwriter comfort letters and updates
                              thereof in customary form and covering matters of

                              reasonably requested by any Freemedic or any such
                              underwriter, attorney, accountant or agent in
                              connection with such registration statement;

                       (vi)   furnish to Freemedic an opinion of counsel for the
                              Parent dated the effective date of such
                              registration statement (or, if such registration
                              includes an underwritten public offering, dated
                              the date of the closing under the underwriting
                              agreement), addressed to the underwriters and to
                              Freemedic, reasonably satisfactory in form and
                              substance to Freemedic and such underwriters; and

                       (vii)  notify Freemedic, at any time a prospectus covered
                              by such registration statement is required to be
                              delivered under the Securities Act, of the
                              happening of any event of which it has knowledge
                              as a result of which the prospectus included in
                              such registration statement, as then in effect,
                              includes an untrue statement of a material fact or
                              omits to state a material fact required to be
                              stated therein or necessary to make the statements
                              therein not misleading in the light of the
                              circumstances then existing.

          9.1.6.  The right of Freemedic to request registration or inclusion in
                  any registration pursuant to this Agreement shall terminate on
                  the date that all Option Shares held or entitled to be held
                  upon exercise or conversion of this Agreement by Freemedic may
                  immediately be sold under Rule 144(k) of the Securities Act,
                  assuming Freemedics' compliance with the provisions of the
                  Rule.

          9.1.7.  In the event that Freemedic wishes to dispose of any Option
                  Shares issued to it prior to their registration with the SEC,
                  then such sale or other disposal of the said Option Shares by
                  Freemedic shall be carried out:-

                  (i)  only after consultation with the Board of Directors of
                       the Parent; and

                  (ii) as unregistered shares exempt from the requirement of SEC
                       registration in compliance with Rule 144 of the
                       Securities Act, or pursuant to Regulation S as defined in
                       Clause 10.1.2 below, or by private placement to
                       accredited investors in compliance with US Securities
                       laws (in the case of an exemption under Rule 144 or
                       Regulation S, such compliance to be evidenced by
                       certificates of an officer of Freemedic, in the case of
                       Rule 144, or of officers of both Freemedic and the
                       transferee in case of Regulation S, and in the case of a
                       private placement, such compliance to be evidenced by an
                       opinion of counsel to Freemedic (in both cases the form
                       of which certificate or opinion is reasonably
                       satisfactory to the Parent).

          9.1.8.  All dealings with the Option Shares by Freemedic and whether
                  or not registered will at all times be subject to compliance
                  by Freemedic and the Parent with the rules of AMEX (or such
                  other national securities exchange or automated quotation
                  system on which the Common Stock is then listed), the SEC and
                  any other regulatory body in connection therewith.

                  Freemedic agrees that it will not offer, transfer, sell,
                  pledge, hypothecate or otherwise dispose of any of the Option
                  Shares, except in compliance with the Securities Act and the
                  rules and regulations of the SEC thereunder, and in compliance
                  with applicable state securities laws. In the event that
                  compliance with this Clause 9 conflicts in any way with such
                  rules or regulations, then the relevant provisions of this
                  Clause 9 shall be varied to ensure compliance therewith.

          9.1.9.  So long as Freemedic owns any of the Option Shares, the Parent
                  shall timely file all reports required to be filed with the
                  SEC pursuant to the Securities Exchange Act of 1934, as
                  amended ("the "Exchange Act"), and the Parent shall not
                  terminate its status as an issuer required to file reports
                  under the Exchange Act even if the Exchange Act or the rules
                  and regulations thereunder would permit such termination. The
                  Parent currently meets, and will take all necessary action to
                  continue to meet, the "registrant requirements" for the use of
                  Form S-3 set forth therein. The Parent shall comply with the
                  Parent's reporting, filing and other obligations under the
                  Exchange Act. 

          9.1.10.

                  (a)  In the event of a registration of any of the Option
                       Shares under the Securities Act, the Parent will
                       indemnify and hold harmless Freemedic, each of its
                       directors and officers and each person, if any, who
                       controls Freemedic within the meaning of the Securities
                       Act, against any losses, claims, damages or liabilities,
                       joint or several, actually made against or incurred by
                       Freemedic or such person under the Securities Act or
                       otherwise, insofar as such losses, claims, damages or
                       liabilities (or actions in respect thereof) arise out of
                       or are based upon any untrue statement or alleged untrue
                       statement of any material fact contained in any
                       registration

                         statement under which such Option Shares were
                         registered, any prospectus contained therein, or any
                         amendment or supplement thereof, or arise out of or are
                         based upon the omission or alleged omission to state
                         therein a material fact required to be stated therein
                         or necessary to make the statements therein in light of
                         the circumstances in which they were made, not
                         misleading, or any violation by the Parent of any rule
                         or regulation promulgated under the Securities Act or
                         any state securities law applicable to the Parent and
                         relating to action or inaction required of the Parent
                         in connection with any such registration, and will
                         reimburse Freemedic, each of its officers and
                         directors, and each person controlling Freemedic for
                         any reasonable legal and any other expenses incurred in
                         connection with defending or settling any such claim,
                         loss, damage, liability or action, provided that the
                         Parent will not be liable in any such case to the
                         extent that any such claim, loss, damage or liability
                         arises out of or is based on any untrue statement or
                         omission based upon written information furnished to
                         the Parent by an instrument duly executed by Freemedic,
                         its officers, directors or any person controlling
                         Freemedic specifically for user therein. The indemnity
                         agreement contained in this Clause 9.1.10 (a) will not
                         apply to amounts paid in settlement of any such loss,
                         claim, damage or liability if such settlement is
                         effected without the consent of the Parent (which
                         consent shall not be unreasonably withheld) unless the
                         Parent waived its right pursuant to Clause 9.1.10(c) to
                         assume the defence of such loss, claim, damage or
                         liability.

                    (b)  Freemedic will, if Option Shares are included in the
                         securities as to which such registration is being
                         effected, indemnify and hold harmless the Parent, each
                         of its directors and officers, each

                         underwriter, if any, of the Parent's securities covered
                         by such a registration statement, each person who
                         controls the Parent and each underwriter within the
                         meaning of the Securities Act, against all claims,
                         losses, expenses, damages and liabilities (or actions
                         in respect thereof) arising out of or based on any
                         untrue statement (or alleged untrue statement) of a
                         material fact contained in any such registration
                         statement or prospectus, or any omission (or alleged
                         omission) to state therein a material fact required to
                         be stated therein or necessary to make the statements
                         therein not misleading, and will reimburse the Parent,
                         such directors, officers, persons or underwriters for
                         any reasonable legal or any other expenses incurred in
                         connection with defending or settling any such claim,
                         loss, damage, liability or action, in each case to the
                         extent, but only to the extent, that such untrue
                         statement (or alleged untrue statement) or omission (or
                         alleged omission) is made in such registration
                         statement or prospectus in reliance upon and in
                         conformity with written information furnished to the
                         Parent by an instrument duly executed by Freemedic its
                         officers, directors or any person controlling Freemedic
                         specifically for use therein. The indemnity agreement
                         contained in this Clause 9.1.10(b) will not apply to
                         amounts paid in settlement of any such loss, claim,
                         damage or liability if such settlement is effected
                         without the consent of Freemedic (which consent shall
                         not be unreasonably withheld) unless Freemedic waived
                         its right pursuant to Clause 9.1.10(c) to assume the
                         defence of such loss, claim, damage or liability.

                    (c)  Each party entitled to indemnification under this
                         Clause 9.1.10 (the "Indemnified Party") shall give
                         notice to the party required to provide indemnification
                         (the "Indemnifying Party") promptly after

                         such Indemnified Party has actual knowledge of any
                         claim as to which indemnity may be sought, and shall
                         permit the Indemnifying Party to assume the defence of
                         such claim or any litigation resulting therefrom,
                         provided that counsel for the Indemnifying Party, who
                         shall conduct the defence of such claim or any
                         litigation resulting therefrom, shall be approved by
                         the Indemnified Party (whose approval shall not
                         unreasonably be withheld), and the Indemnified Party
                         may participate in such defence at such party's
                         expense, and provided further that the failure of any
                         Indemnified Party to give notice as provided herein
                         shall not relieve the Indemnifying Party of its
                         obligations under this Clause 9.1.10 to the extent such
                         failure is not prejudicial. In case the defendants in
                         any such action include both the Indemnified Party and
                         the Indemnifying Party and the Indemnified Party shall
                         have reasonably concluded that there may be one or more
                         legal defences available to it which are different from
                         or additional to those available to the Indemnifying
                         Party, the Indemnifying Party shall not have the right
                         to direct the defence of such action on behalf of the
                         Indemnified Party and the Indemnified Party shall have
                         the right to select separate counsel to defend such
                         action on behalf of the Indemnified Party and in such
                         event the Indemnifying Party shall be liable for the
                         legal and other costs and expenses associated with such
                         separate counsel. No Indemnifying Party in the defence

                         shall survive the registration and sale of any
                         securities by any person entitled to indemnification
                         hereunder and the expiration or termination of this

                    Shares (or other securities of the Parent held by Freemedic)
                    other than those included in the registration, during the
                    one hundred and eighty day period following the effective

                    to a registration relating solely to employee benefit plans
                    on Form S-8 or similar forms that may be promulgated in the
                    future, or a registration relating solely to a Commission
                    Rule 145 transaction on Form S-4 or similar forms that may
                    be promulgated in the future. The Parent may impose stop-
                    transfer instructions with respect to the shares (or
                    securities) subject to the foregoing restriction until the
                    end of the said one hundred and eighty day period.

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

     5.1.  The provisions of this Clause 5 shall be in addition to and not in
           substitution for those terms set out in the Licence. In the event of
           a conflict between the provisions of this Clause 5 and the terms of
           the Licence, the terms of the Licence shall prevail.

     5.2.  During the continuance hereof, the Company hereby grants to each of
           the Medical School and the Trust such non-exclusive, royalty free
           licence to use the Company IPR as may be necessary for the purpose of
           carrying out the Experimental Work in 

                                       12

           all times remain vested in the Company or the Parent, as appropriate.

     5.3.  The Company hereby warrants that it is the registered proprietor or
           the licensee under the Patents. The Company hereby warrants that to
           the best of its knowledge and belief but without having made any
           enquiries, investigations and searches, the Medical School and the
           Trust will not infringe the Intellectual Property Rights of any third
           party in using such Patents in the performance of the Experimental
           Work in accordance with the terms of this Agreement. Notwithstanding
           any other provision of this Agreement, the Company hereby warrants
           that it is entitled to grant the Licence of the Patents included in
           Clause 5.2 and that the consent of Thermedics Inc. or any other third
           party that owns an interest in the Patents is not required to enable

           terms. If, for any reason, the Parent decides not to seek a licence
           of the Project IPR or refuses to enter into a licence in respect of
           the Project IPR in accordance with the terms of the Licence,
           Freemedic shall be entitled to grant a licence of the Project IPR to
           any person for the purpose envisaged in the Licence.

     those consents and fulfil those requirements at the Company's expense,
     whether statutory or otherwise which are necessary to allow the commercial
     development and exploitation of the Products by the Company and/or the
     Parent.  The Company shall for the avoidance of doubt be the sole
     beneficiary and recipient of any income arising directly or indirectly from
     the exploitation of the Products tested pursuant to Project One.  The terms

           in accordance with the terms of this Clause 7 and, if so required by
           the other, the Company or the Medical School will procure that their
           employees, agents and sub-contractors or the Parent or the Trust and

EXECUTIVE SUMMARY

This is an application to support the investigation of a small diameter
compliant vascular prosthesis.  The application would be in patients presenting
with critical limb ischemia (threatened limb loss due to poor circulation) which
affects 1 in 2,500 of the population.

The best material for this procedure is autologous saphenous vein.  However, in
30% of patients the vein cannot be used and an alternative conduit must be
sought.

The market is worth some (Pounds)100 million per annum. It is dominated by
American-manufactured products utilizing expanded P.T.F.E., the use of which is
limited by the diameter of the grafts being more than or equal to 6 mm, with
poor results in critical applications. There is therefore a need for a 4-5 mm
internal diameter prosthetic vascular graft for this type of distal arterial
reconstruction.

The programme will bring together the commercial, technical and development
resources of the commercial partner with the research, scientific and surgical
resources of the department of vascular surgery at The Royal Free Hospital
Medical School who have considerable specialist experience and international
recognition in this field.

The development process will encompass a new approach to the design of vascular
grafts in that we intend to address the main reasons for graft failure by
utilising technologies to overcome the failure modes.  For example, the graft
will have anti-thrombogenic flow lining which could be provided  by a layer of
endothelial cells or alternative technologies.  The graft will also be compliant
to match the physical and mechanical characteristics of a native blood vessel
enabling the transmission of pulsatile blood flow.

The project will last two years and is divided into a series of tasks.  These
tasks take the programme from investigation of a polycarbonate urethane vascular
graft developed by CardioTech for haemodialysis access through a series of steps
to pilot clinical evaluation by the University partner for peripheral vascular
bypass.  Additional methods or technologies which could potentially enhance
graft performance will be investigated.

SECTION 1

THE NEED

The United Kingdom Vascular Society recently reported on the prevalence of
patients presenting to vascular surgeons with critical limb ischaemia
(threatened limb loss due to poor circulation) to be 1 in 2,500 of the
population.  The peak occurrence is between 70 and 79 years of age.  This burden
on the NHS is expected to increase as the population ages.  To avoid 
amputation, peripheral arterial bypass surgery is required, usually to a small
artery in the calf or foot.  Successful revascularisation has been clearly shown
to be considerably less expensive than amputation and subsequent rehabilitation.
The best material for this procedure is autologous saphenous vein.  However, in
30% of patients the vein cannot be used and an alternative conduit must be
sought.  There is therefore a need for a 4-5 mm internal diameter prosthetic
vascular graft for this type of distal arterial reconstruction.

THE PROBLEM

Below knee prosthetic grafting is currently restricted by unacceptably poor
patency rates achieved with existing products.

The principal causes of graft failure are:

 .  Early thrombosis at less than one month due to the inherent
   thrombogenicity of current prosthetic materials.
 .  Diameter mismatch between artery and graft.
 .  Low compliance and major compliance mismatch of current prosthetic
   materials resulting in inadequate flow rates.
 .  Neo-intimal hyperplasia between one and twelve months.
 .  Disease progression usually beyond the distal anastomosis.
 .  Inadequate inflow.

THE SOLUTION

To develop a small diameter synthetic vascular graft with the potential for
improved clinical performance by bringing together several technologies and a
multidisciplinary team who have the relevant background and skills to undertake
and complete the project.

This is a new approach to the research and design of vascular grafts.
Historically, the development of vascular grafts has been directed at one
factor, such as material characteristics, kink resistance or thrombogenicity,
etc.  Graft failure is however a multifactorial issue.  Performance and clinical
outcome will not be substantially improved without addressing the major issues
which contribute to graft failure in combination with novel technologies which
can improve performance.

An antithrombotic surface to inhibit thrombus formation and form an interface
with blood flowing through the graft can be enabled by endothelial cell lining
of the graft surface. This is  considered a likely successful route to achieving
such an interface.  However, several new technologies are available to modify
the flow surface of the graft and achieve a low thrombotic flow lining without
the need for biological materials to be introduced.

Neo-intimal hyperplasia, which causes later graft failure, tends to occur when
the endothelium is damaged, although this can be inhibited by restoration of the
cell monolayer by cell seeding.  An alternative route would be in bonding
certain pharmaceutical or biotechnology products onto the graft surface which
could minimise the potential for hyperplasia development.

Arteries display a characteristic known as compliance which in lay terms can
best be expressed as elasticity (but not in the scientific sense).  This
property gives the artery elastic recoil which takes place after each arterial
pulse has passed, and thus enhances blood flow.  This property is particularly
marked in low blood pressure states, thus enhancing blood flow even further.
All prosthetic grafts to date have very low compliance, i.e. they are rigid and
non-elastic.  Enhancing the compliance of a small calibre prosthetic graft would
be expected to improve the low flow often seen in this situation.  Furthermore a
compliance prosthetic graft would reduce the mismatch in compliance between
graft and native artery.  Low graft compliance and compliance mismatch are
recognized as important factors in failure of small calibre prosthetic grafts.
Design and development of a compliant vascular graft should remove this cause of
graft failure.

The design criteria will be to mimic the mechanical and physical properties of a
natural artery allowing the maintenance of pulsatile flow and compliance in
combination with an antithrombotic flow lining.  This will allow patency to be
maintained in smaller diameters even with low blood flow.

THE BENEFITS

PATIENT

For the patient, successful bypass allows resumption of a normal lifestyle,
relief from pain, ulceration and/or gangrene, and avoidance of amputation.
Improved graft performance would reduce the rates of secondary reconstructions
and amputation, with their attendant risks for the generally elderly population.

NHS

For the NHS, it has been clearly shown that limb salvage, at an estimated
(Pounds)7,500 per patient, with its attendant patient benefits, is significantly
less expensive than amputation and the subsequent support requirements,
conservatively estimated at (Pounds)25,000 per patient.  This would offer a
potential saving of around (Pounds)66 million per annum even if only 25% of
patients are able to benefit. Reduction in expensive revisional surgery, a
reduction in the burden of community care services, and an increase in the case
load throughput and bed occupancy rates are among the major benefits.

COMMERCIAL

The development of a successful small bore vascular graft could bring several
diverse benefits

 .  major capital investment and job creation in a high technology manufacturing
   company
 .  improved performance by the UK health care sector in international markets
 .  international recognition that collaborative medical implant programmes can
   be successfully completed in the UK

SECTION 2

PARTICIPANTS

The project is proposed by CardioTech International Ltd, the only UK based
company manufacturing polycarbonate urethane vascular access grafts, and the
University Department of Vascular Surgery at the Royal Free Hospital School of
Medicine, London.


CARDIOTECH

COMPANY STRUCTURE

CardioTech was created in May of 1996 as a spin-off from PolyMedica Industries
Inc. into a stand-alone company. The company comprises CardioTech International
Inc. which is quoted on the American Stock Exchange and specialises in the
development, production and marketing of advanced polymer biomaterials for the
medical device industry, and CardioTech International Ltd which is undertaking a
programme of small diameter vascular graft development which is a continuation
of the work undertaken over the last three years by  PolyMedica Industrioe.

Our vascular graft programme is principally based in the UK.  Research,
development, testing and production of vascular grafts is being carried out at
our premises near Chester.

COMPETENCIES

Staff employed by CardioTech (previously at Polymedica) have already developed a
polycarbonate Vascular Access Graft used for haemodialysis.  We have therefore
carried out a considerable programme of process development, in vitro and in
vivo research into the biodurability of our material ChronoFlex and the
ChronoFlex vascular access graft which has enter clinical trials in both Holland
and France.  The information generated by CardioTech during graft development
will be used to support an application to the Ethics Committee to commence
limited clinical evaluation.

MATERIALS

ChronoFlex will be used to produce the new graft. It is a biodurable
polycarbonate based polyurethane which comprises the following components:

 .  polycarbonate polyol
 .  methylene diisocyanate
 .  ethylene diamaine
 .  1,3 diaminocyclohexane

                                       6
<PAGE>
 
CardioTech holds USA patent 6254662 for ChronoFlex.  The inventor of
ChronoFlex, Dr. M. Szycher, is Chairman of the company and Chief Technical
Officer.  CardioTech holds a perpetual worldwide license from PolyMedica to
manufacture and use ChronoFlex for medical applications.

VASCULAR GRAFT PRODUCTION

Our patented process involved what we term "low temperature cast coagulation".
In this system we gently extrude polymer solution onto the smooth surface of a
mandrel. The polymer solution comprises a solution grade ChronoFlex, a water
soluble filler of between 10 and 60% by weight and a surfactant in an amount
between 1 and 10% by weight. The mandrel and extrusion head rotate in
synchronization, minimising shear and residual stress, whilst a pair of 2.5
metre long mandrels are drawn through the twin extrusion heads into a coagulant
maintained at 40 degrees C. During phased coagulation the fillers prevent
collapse of the structure as the solvent disperses and the filler dissolves into
the coagulant, resulting in a single layer uniform microporous structure which
avoids the danger of delamination and subsequent loss of strength, maintaining
cross section.

By manipulating the process conditions, it is possible for grafts to be produced
with different physical and mechanical characteristics; an example would be a
very porous graft allowing rapid cellular ingrowth which could be suited to
venous applications.

CardioTech owns European patent 0286220, USA patent 5132066 and Japanese patent
1813534 covering aspects of graft production.

ROUTE TO MARKET

When the graft is ready for introduction, the Medical Device Directives will be
mandatory.  The peripheral graft will obviously require a CE mark and as a class
11b implant able device it will require clinical data to comply with the
essential requirements.  This information is expected to come from limited
clinical investigations carried out by the academic partner.

DISTRIBUTION

There are three possible methods:

1.  Direct via staff employed by CardioTech
2.  Indirect via distributors engaged by CardioTech
3.  Creating a strategic alliance to access an existing international marketing
    and sales network with a major health care company

It is too early to decide which option will be favoured. However, by mid 1997
our vascular access graft will become a commercial product and we will have a
distribution in place which may be suitable for the peripheral graft.

OPPORTUNITY

The UK market is estimated at (Pounds)1.5 million per annum, the total EU market
at (Pounds)40 million and the global business (Pounds)125 million per annum.
The market is growing at 10% per annum and is dominated by American-manufactured
products.  The EU has suspended import duty on certain categories of vascular g
rafts because there is no EU manufacturer.

THE UNIVERSITY DEPARTMENT OF SURGERY AT THE ROYAL FREE HOSPITAL

The Department is recognised for its research into several aspects of vascular
biology, in particular the role of compliance in vascular grafting.  Vascular
biological research here has also focused on neo-intimal hyperplasia and
endothelial cell graft seeding. The head of Department has been involved in
compliance research initially at Harvard and over the last seven years at the
Royal Free Hospital School of Medicine.  The Department has a Principal
Biophysicist, a specialist in vascular flow dynamics and measurement who has
developed a highly accurate method of compliance measurement using digital x-ray
angiographic techniques.  For the first time this method allows accurate
compliance measurement of implanted grafts and native arteries in patients.  In
addition there is an experienced cell culture technician and a vascular fellow
of two years experience of research into compliance and vascular flow
measurement.  The department is set up with a vascular Haemodynamic laboratory
for in vitro and in vivo vascular graft studies.  This department has great
expertise in the field of compliance in vascular surgery.

The methodologies of immunohistochemistry, autoradiography and electron
microscopy are in routine use in this Department.  The methodology of in vitro
study of prosthetic grafts over the long term (i.e. longer than 24 hours) under
physiological conditions is well developed.  There are superb facilities for
large animal studies focused on the pig with established prosthetic graft
evaluation within this context.

The IRC of Biomaterials Research headed by Professor Dennis Chapman is housed
within the University Department of Surgery.  In collaboration there has been
research into the use of non-thrombogenic biomaterials in lining prosthetic
graft materials both in vitro and using a carotid interposition model in sheep.

SECTION 3

PROJECT PLAN OUTLINE

Research and experimental work will be carried out by the Department of Vascular
Surgery at The Royal Free Hospital Medical School.  CardiTech will manufacture
polycarbonate urethane grafts for the project at its facilities near Chester.

The present polycarbonate graft which has been developed for vascular access by
CardioTech will be studied in vitro by the academic partner to ascertain its
suitability to meet the more demanding requirements in peripheral vascular
bypass grafting.

The results from evaluation will be combined with study results and other
development information from CardioTech International Ltd to allow an
application to be made to an Ethics Committee leading to a pilot clinical
investigation with the objective of determining the short term clinical
performance of the grafts, providing the clinical information required to comply
with the essential requirements of the EU Medical Devices Directive.  The
clinical investigation will commence no later than May 1998.

In parallel to this work evaluation of alternative adjunctive technologies will
be instigated.  In particular endothelial cell seeding of the ChronoFlex will be
undertaken to reduce the thrombogenicity of the graft surface.

Grafts will go through a selection process of physical and mechanical testing by
CardioTech (ISO/DS 7198 Tubular Vascular Grafts) and in vitro and in vivo
research at the laboratories of the academic partner leading to clinical
evaluation.

The project will consist of a series of tasks which are described in outline as
follows:

                                possible kinking of the graft at flexion points.
                                CardioTech will add to the existing access graft
                                an external supporting layer to improve the 
                                anti-kinking properties of the graft for 
                                peripheral use. The reinforced peripheral 
                                graft will be made in both 4 and 5 mm internal 
                                diameters to provide a closer match to the 
                                natural vessels.
                                           
                                        Grafts will be manufactured by CTI for
                                        evaluation of the compliance
                                        characteristics of the polycarbonate
                                        urethane grafts in vitro by using
                                        oohotracker and angiographic methods,
                                        obtaining compliance, diameter and
                                        pressure curves for a range of
                                        physiological flow rates.

                                        Initially research the compliance and
                                        shear stress characteristics of human
                                        artery in vivo and in vitro at
                                        physiological flow conditions by
                                        echotracker and angiographic methods.
                                        This will establish the physical
                                        characteristics of a blood voocol and
                                        generate a range of compliance and
                                        pressure curves at different pulsatile
                                        blood flow waveforms for human artery
                                        and compliant graft.

Objective:                      Research the ability of the graft to tolerate
                                low blood flow.

Description of Work:            Grafts are placed in a pulsatile flow circuit to
                                simulate human femoral artery conditions. Flow
                                and pressure rates are modified to establish
                                conditions prevalent in a range of diseased
                                femoral artery conditions and by gross and
                                microscopic methods to investigate the ability
                                of surface to tolerate low blood flow. This
                                would be assessed over one week at sterillised
                                conditions. The aim is to access the physical
                                characteristics over time in a condition similar
                                to in vivo.

Deliverable:                    An analysis of the peripheral vascular graft to
                                provide the

Objective:                      Research into the effect of anastomotic
                                technique and materials on compliance.

Responsible:                    Royal Free Hospital, dept. of surgery.

Description of Work:            In vivo acute studies of anastomotic compliance
                                will be performed to research the effects of
                                commonly used suture materials, i.e. proline and
                                novafil sutures (this is a more elastic or
                                compliant suture material provided by Davis &
                                Geck) and suture technique, i.e. continuous and
                                interrupted on the in situ rentention of
                                compliance.

                                The haemodynamic effect of anastomotic angle
                                will also be studied (including the
                                configuration used in clinical practice).
                                Measurements at the anastomosis will include
                                shear stress, shear rate and turbulence.

Objective:                      Long term in vivo compliance and performance
                                study.

                                        Having identified the best anastomotic
                                        methodology and materials by actue in
                                        vivo experimental investigation we will
                                        begin research into the acute and
                                        chronic in vivo compliance of the graft.
                                        This will be done by implanting grafts
                                        into a porcine model. Compliance will be
                                        measured at implant and at predetermined
                                        intervals using an angiographic
                                        technique.

                                        At explant, in addition to compliance
                                        and performance measurements, the grafts
                                        will be perfused-fixed and studied by
                                        autoradiograpy, and
                                        immunohistochemistry, and electron
                                        microscopy. Redial tensile strength and
                                        molecular weight determination are also
                                        undertaken on the explants to
                                        demonstrate biodurability.

Deliverable:                    Analysis of biological response to the implant,
                                retention of compliance characteristics, and
                                performance information needed to justify
                                limited clinical evaluation and recommendations
                                for implantation technique.

2.   RIGHTS GRANTED
     --------------

     2.1. During the continuance hereof, the Licensor grants to the Licensee, on
          the terms set out in this Agreement, an exclusive licence to use the
          Intellectual Property in the Territory for the Primary Purpose under
          the terms of this Agreement.

     2.2. The Licensee shall not be entitled:-

          2.2.1.  to supply any Kit with any product other than any Vascular
                  Graft, save as provided in Clauses 2.3 or 2.4;

          2.2.2.  to supply any Kit independently from any Vascular Graft save
                  that with the prior written consent of the Licensor (such
                  consent not to be unreasonably withheld or delayed), the
                  Licensee shall be entitled to supply any Kit separately from
                  any Vascular Graft for practical production or supply reasons,
                  provided that the Licensee makes such supply only on such
                  terms as the Licensor may reasonably require and supplies all
                  Kits on the condition (but without guaranteeing the compliance
                  by any third party with such condition) that they be used with
                  a Vascular Graft and that the Kit must not be used with any
                  product other than the Vascular Graft; and
<PAGE>
 
          2.2.3.  to use any of the Intellectual Property save as expressly
                  licensed pursuant to Clause 2.1.

          Where in accordance with Clause 2.2.2 the Licensee or any Sub-Licensee
          supplies any Kit separately from any Vascular Graft, the definition of
          Products shall be deemed to include any such Kit.

          Where the Licensee or any Sub-licensee supplies any Kit it will do so
          on the condition (but without guaranteeing the compliance by any third
          party with such condition) that the Kit is only to be used with the
          Vascular Graft.

     2.3. Subject to Clause 2.4 and 2.5 below, if at any time during the Minimum
          Period the Licensee can demonstrate to the reasonable satisfaction of
          the Licensor that:-

          (i)   it has developed a Stent to which the Process can be applied; or

          (ii)  it has acquired the right to manufacture and supply any such
                Stent; or

          (iii) either (i) or (ii) above is imminent;

          then the exclusive licence granted pursuant to Clause 2.1 shall in
          addition to Primary Products, extend to cover the Secondary Products
          and the provisions of clauses 2.1 and 2.2 shall apply mutatis mutandis
          to include such Secondary Purpose.

     2.4. Subject to Clause 2.5 below, if at any time during the Minimum Period,
          provided that no extension of the licence for the Secondary Purpose as
          envisaged by Clause 2.3 above shall then have been granted or such
          obligation shall have arisen, the Licensor shall receive an approach
          from any third party wishing to perform the Secondary Purpose, the
          Licensor shall as soon as reasonably practicable thereafter give to
          the Licensee details in writing of such approach (subject to any
          duties of confidentiality owed by the Licensor to any such third party
          provided 
<PAGE>
 
          that the Licensor shall use all reasonable endeavours to ensure that
          such obligations of confidentiality do not restrict the provision by
          the Licensor to the Licensee of sufficient information to enable it to
          exercise its rights under this Clause 2.4), and shall allow the
          Licensee a reasonable period of time (being not less than 60 days) in
          which to demonstrate to the reasonable satisfaction of the Licensor
          that the Licensee is able to put such Secondary Products as are the
          subject of the third party approach into such a form as to enable them
          to be sold on the open market in a shorter period than it would have
          taken the said third party to do so. If the Licensee is able to
          demonstrate such capability in accordance with this Clause 2.4 then
          the exclusive licence granted pursuant to Clause 2.1 shall, in
          addition to the Primary Products, extend to cover the Secondary
          Products and the provisions of Clauses 2.1 and 2.2 shall apply mutatis
          mutandis to include such Secondary Purpose.

     2.5. If the Licensee is planning to enter into the market for Stents in the
          near future, it shall be entitled to request an extension of the
          option period provided in clauses 2.3 and 2.4 for a further 12 months
          from the expiry of the Minimum Period and the Licensor shall not
          unreasonably withhold or delay its consent to such an extension
          provided the Licensee demonstrates to the reasonable satisfaction of
          the Licensor that it is taking active steps to enter that market.

          breach of any of the provisions of this Agreement on the part of the

                  manufactured by the Licensee or Sub Licensee with the
                  permission of the Licensor, the terms of such wording and its

          5.1.2.  ensure that all literature relating to the Products includes a
                  notice in similar terms.

6.   OWNERSHIP OF THE INTELLECTUAL PROPERTY
     --------------------------------------

     6.1. Subject to the provisions of this Clause 6.1 the Licensor hereby
          warrants represents and undertakes to the Licensee:-

          6.1.1.  that it has the right and authority to enter into this
                  Agreement; and

          6.1.2.  that it will notify the Licensee in writing immediately upon
                  it receiving written notification that the use of any of the
                  Intellectual Property on or in relation to the Products in any
                  part of the Territory in accordance with the terms of this
                  Agreement 
<PAGE>
 
                  infringes or is likely to infringe the Intellectual Property
                  Rights of any third party, but for the avoidance of doubt the
                  provisions of this clause 6.1.2 will not impose a positive
                  duty upon the Licensor to make specific enquiries in respect
                  thereof.

          The Licensor acknowledges and confirms that the Licensor has not
          sought the consent of Thermedics Inc. or any other third party which
          owns any interest in any Patents as defined in the Research Agreement
          and the Licensee warrants that such consent is not required for the
          purposes of this Agreement.

     6.2. Where any of the Know-How is patentable, the Licensor may in its
          absolute discretion apply for Patents in any country within the
          Territory at the Licensor's cost. Where the Licensor so applies for
          any Patent, it will promptly pay all registration, renewal and other
          related fees necessary to maintain the registrations of any Patents on
          the relevant register of patents ("the Register") within the said
          countries within the Territory and where such Patents are applications
          shall prosecute the applications with due diligence during the term of
          this Agreement.

     6.3. If the Licensor notifies the Licensee in writing that it does not
          intend to apply for any Patent in any of the countries within the
          Territory in accordance with Clause 6.2 above, then the Licensee shall
          itself be entitled to apply for any such Patent in the relevant
          country in the name of the Licensor at the cost of the Licensee and in
          accordance with the reasonable directions of the Licensor and, for so
          long as the Licensee shall remain exclusively entitled thereto, shall
          promptly pay all registration, renewal and other fees necessary to
          maintain the registrations of such Patents on the Register within such
          country, and where such Patents are applications, shall prosecute the
          applications with due diligence during the term of this Agreement.

     6.4. In the event that the Licensor, or where relevant the Licensee applies
          for a Patent pursuant to Clauses 6.2 or 6.3 above for the purpose of,
          or
<PAGE>
 
          in connection with the granting of a licence to the Licensee, then for
          so long as such exclusive licence enures for the benefit of the
          Licensee, the party so applying shall be entitled to require the other
          party to provide such assistance as the applying party may reasonably
          request in connection with the prosecution of such application,
          subject to the applying party reimbursing the other for all fees,
          costs and expenses incurred by it in providing such assistance.

     6.5. Each of the Licensor and the Licensee undertakes not to do or permit
          to be done any act which would or might jeopardise or invalidate the
          registration of any Patent nor to do or permit any act which might
          assist or give rise to an application to remove any of the Patents
          from the Register or which might prejudice the right or title of the
          Licensor to any of the Intellectual Property.

     6.6. The Licensee will on request give or procure that there is given to
          the Licensor or its duly authorised representative any information as
          to the use of the Intellectual Property which the Licensor may
          reasonably require.

     6.7. The Licensee shall assist the Licensor as may be reasonably necessary
          (including by executing any necessary documents) in recording the
          Licensee as a licensee of the Patents on the Register and the Licensee
          hereby agrees that such entry may be cancelled by the Licensor on
          termination of this Agreement, for whatever reason, and that it will
          assist the Licensor so far as may be necessary to achieve such
          cancellation including by executing or procuring that there is
          executed at the request of the Licensor any documents necessary for
          that purpose, subject to the Licensor bearing the costs relating to
          the removal of such entry where this Agreement is terminated by reason
          of breach on the part of the Licensor.

7.   INFRINGEMENTS
     -------------

     7.1. To the extent that the same relates to the exclusive licence or option
          granted or to be granted to the Licensee hereunder, each of the
          parties hereto shall as soon as it becomes aware thereof give to the
          other in writing full particulars of any activity by any person which
          amounts or might amount either to infringement of any of the Patents
          or misuse of the Know-how.

     7.2. To the extent that the same relates to the exclusive licence or option
          granted or to be granted to the Licensee hereunder, then without
          prejudice to the requirement set out in Clause 6.1.2 above, if either
          party hereto becomes aware that any person either alleges that any of
          the Patents is invalid or that the use of the Intellectual Property
          infringes any Intellectual Property Rights of any third party or the
          Intellectual Property is otherwise attacked or challenged such party
          shall immediately give to the other full particulars in writing
          thereof. Subject to Clause 7.3, the Licensee shall make no comments or
          admission to any third party in respect thereof without the prior
          written consent of the Licensor.

     7.3. Where any third party alleges that the Licensee has infringed its
          Intellectual Property Rights as a result of the manufacture, use or
          supply of any Products by or on behalf of the Licensee in any of the
          Territories, the Licensee shall be responsible for conducting any
          proceedings relating to its defence and shall consult with the
          Licensor in respect of any such proceedings. The Licensor will give
          the Licensee all such assistance as is reasonable in the
          circumstances. The Licensee shall be responsible for all costs
          relating to such proceedings (including the reasonable costs of the
          Licensor in providing such assistance) and shall keep any damages and
          costs awarded.

     7.4. Where there is any infringement or suspected infringement of any of
          the Patents any attack or challenge on any of the Patents or any
<PAGE>
 
          unauthorised disclosure or mis-use of the Know-How within any country
          within the Territory, the Licensor shall at its own option and expense
          have the sole conduct of any proceedings in respect thereof and will
          retain any damages and costs awarded to it. The Licensor shall consult
          with the Licensee in connection with such proceedings.

     7.5. Where there is any infringement or suspected infringement of any of
          the Patents or any unauthorised disclosure or misuse of the Know how
          within any country within the Territory and where the Licensor
          initiates proceedings in respect thereof, then to the extent that such
          infringement, disclosure or misuse relates to any of the Products, the
          Licensor will at the Licensee's written request use its reasonable
          endeavours to join the Licensee in as co-plaintiff in such
          proceedings. In such circumstances the Licensee will bear its own
          costs and expenses relating to such proceedings and will retain any
          damages or costs awarded to it.

     7.6. Where the Licensor decides not to take any action in respect of-

          (i)  any attack or challenge on any of the Patents; or

          (ii) any infringement or suspected infringement of any of the Patents
               or any unauthorised disclosure or misuse of any of the Know-how
               which relates to the Products;

          the Licensor shall notify the Licensee and, subject to Clauses 7.7 and
          7.8 below, shall permit the Licensee at its own option and expense to
          have the sole conduct of any proceedings relating to the same and the
          Licensee shall be entitled to retain any damages and costs awarded to
          it. The Licensee shall consult with the Licensor in connection with
          such proceedings. Where the Licensee commences any infringement
          proceedings in accordance with this Clause 7.6 the Licensee shall, at
          the Licensor's written request use its reasonable endeavours to join
          the Licensor in as co-plaintiff in such proceedings. In such
          circumstances
<PAGE>
 
          the Licensor will bear its own costs and expenses relating to such
          proceedings and will retain any damages or costs awarded to it.

     7.7. Where a situation as envisaged by Clause 7.6(i) or 7.6 (ii) above has
          arisen but the Licensee is not the sole Licensee in respect of the
          Intellectual Property giving rise to such action, then the Licensor
          shall, acting reasonably and having full regard of the wishes,
          available financial resources and potential loss of such party, decide
          which of the Licensee or the other licensee(s) shall take action in
          respect of the same. Where procedurally possible, such decisions shall
          not preclude the Licensor or Licensee from being joined into such
          proceedings as co-plaintiffs in which case the provisions of Clause
          7.5 and 7.6 in respect thereof shall apply mutatis mutandis.

     7.8. In any proceedings to which either the Licensor or the Licensee (as
          the case may be) is a party hereunder pursuant to Clauses 7.4 to 7.7
          (inclusive), then the other party shall give the Licensor or the
          Licensee (as the case may be) such assistance as that party may
          reasonably request in connection with such proceedings, subject to the
          Licensor or the Licensee (as the case may be) meeting that other
          party's reasonable costs and expenses in connection therewith, save
          that where both parties are co-plaintiffs in respect of any such
          proceedings, they shall each bear their own costs and expenses
          incurred in connection with any such proceedings.

                         sold by or on behalf of the Licensee or any Sub-
                         Licensee (calculated by reference to the aggregate Net
                         Sale Price) = 4%;

                  (iii)  (Pounds)7,500,001 + of such Products sold by or on
                         behalf of the Licensee or any Sub-Licensee (calculated
                         by reference to the aggregate Net Sale Price) = 2%.

          8.2.2.  in respect of all Products sold by or on behalf of the
                  Licensee or any Sub-licensee which have either been
                  manufactured or sold in any country where no Patent subsists,
                  a royalty of 2% of the Net Sale Price of all such Products,
                  irrespective or the quantity of such Products sold.

          For the avoidance of doubt, the Licensee will not in any circumstances
          be required under Clause 8.2 to pay any royalties twice in respect of
          the same unit of Product.

     8.3. For the purpose of calculating the royalty payable to the Licensee by
          the Licensor hereunder, there shall be a disregard of (Pounds)80,000
          with the effect that the Licensee shall be released from any liability
          to pay the first (Pounds)80,000 of royalties calculated as due on
          sales of the Products by or on behalf of the Licensee pursuant to
          Clause 8.2.
<PAGE>
 
     8.4. For the avoidance of doubt any royalty calculations made hereunder
          shall be based upon the royalty rate prevailing in that part of the
          Territory in which the Product was either manufactured or supplied
          whichever is the greater.

     8.5. In the event that the Licensee or any Sub-licensee supplies any
          Products to any connected person, such supply shall be ignored for the
          purposes of calculating the royalties due under this Clause 8 and the
          Licensee shall pay the Licensor royalties calculated in accordance
          with this Clause 8 by reference to the Net Sales Price of the Products
          when disposed of by such connected person to an unconnected person.

     8.6. If any Products are incorporated in any other equipment or apparatus
          or included as part of a larger kit sold by the Licensee or any Sub-
          licensee and the price of the Product is included in the price of such
          other equipment, apparatus or kit, the Net Sale Price for the purpose
          of calculating royalties due under this Agreement shall be deemed to
          be that proportion of the Net Sale Price of that other equipment,
          apparatus or kit which is fairly attributable to the Products,
          comparing the manufacturing cost of the other equipment, apparatus or
          other parts of the kit to that of the Products as components thereof.
          Notwithstanding the above, where any Product supplied is a Kit
          incorporating any Vascular Graft of Stent, the Net Sales Price shall
          be the price of the Kit and Vascular Graft or the Kit and the Stent
          (as appropriate).

     8.7. For the purpose of this Agreement a calendar year will commence on 1st
          January in each year and expire on the following 31st December. The
          Licensee shall within 30 days of the first Quarter Day following the
          Commencement Date and within 30 days of each following (or subsequent)
          Quarter Day provide a statement to the Licensor giving particulars of
          the sales of the Products by the Licensee and any Sub Licensee during
          the preceding quarter (or in the first quarter during the period from
          the Commencement Date to the first Quarter Day) showing
<PAGE>
 
          the quantity of the Products sold, the price charged in which of the
          Territories such Products were both manufactured and sold, any
          discounts or other rebates given, the Net Sale Price and the royalty
          due and if more than one type of the Products is sold, showing such
          information for each type, together with any other particulars as the
          Licensor may reasonably require and shall pay the royalties to the
          Licensor at the same time as rendering the statement.

     8.8. All sums payable hereunder are exclusive of Value Added Tax, which
          shall in addition be payable by the Licensee where appropriate. All
          royalties and other payments due under this Agreement by the Licensee
          shall be paid without deduction or withholding in respect of duties,
          taxes or charges levied or imposed by any taxation authority under the
          laws of any country unless the deduction or withholding is required by
          the law of that country. In which event, the Licensee shall provide to
          the Licensor either an official receipt from the relevant taxation
          authority in respect of all amounts so deducted or withheld or (if not
          available) a certificate of deduction or equivalent evidence to enable
          the Licensor to obtain credit for the tax deducted or to claim from
          double taxation (if such relief is available).

     8.9. The Licensee shall and shall procure so far as it is able that its Sub
          Licensee shall keep separate , detailed, true and accurate books and
          records of all sales of the Products to enable the Licensor to check
          the accuracy of the information contained in the statements rendered
          under clause 8.7, such books and records to be retained by the
          Licensee and any other Sub-Licensees for at least three years from the
          date of their creation. The Licensor shall be entitled at its expense
          to inspect such books and records by its authorised representative or
          representatives on reasonable notice during business hours and to take
          copies of or extracts from such books and records, save that this
          right shall not be exercisable in respect of any statement if no
          inspection has been made within three years of its being rendered to
          the Licensor. In the event
<PAGE>
 
           that the statements rendered under clause 8.7 are inaccurate by more
           than 5 per cent, the costs of such inspection shall be paid by the
           Licensee. Any information about the business of the Licensee which
           may be obtained by the Licensor as a result of any such inspection
           and which does not relate to the Products shall be kept confidential
           by the Licensor.

     8.10. The Licensee shall supply to the Licensor within 60 days of the end
           of each Year of this Agreement a certificate in writing by its
           auditors certifying the aggregate Net Sale Price of the Products sold
           or otherwise disposed of by the Licensee or any Sub-Licensee that
           Year and the amount of royalty due. The rendering of such certificate
           shall not preclude the right of inspection given to the Licensor in
           clause 8.8.

                  to carry on business or takes or suffers any similar action

     9.2. Termination of this Agreement for whatever reason shall not affect the
          accrued rights of the parties arising in any way out of this Agreement

          at the date of termination of this Agreement the Licensee may, but
          only with the Licensor's specific permission, sell such stock on the
          terms hereof or such other terms as may be reasonably agreed.

     9.4. Upon termination or expiry of this Agreement the following Clauses

                    Confidential Information for the purposes of this Agreement,
                    but only to the extent necessary to enable it to perform its
                    obligations under this Agreement and provided that it shall
                    remain responsible for procuring that its employees do not
                    further disclose the Confidential Information or use it for
                    any purpose other than to assist the receiving party in
                    performing its obligations under this Agreement.

     10.3. Each party shall be responsible for the compliance with this Clause
           10 on the part of its employees or any other persons to whom such

           Confidential Information which:-

           10.4.1.  the disclosing party in writing authorises the receiving
                    party to disclose;

           10.4.2.  is or comes into the public domain other than through any
                    act or default either directly or indirectly of the
                    receiving party, its officers, employees, agents,
                    representative or Sub-licensees;

           10.4.3.  the receiving party can prove by documentary evidence was

                    information;

           10.4.4.  is subsequently disclosed to the receiving party by a person
                    who did not acquire the information directly or indirectly

                    provided that the receiving party uses its best endeavours
                    to limit such disclosure and to provide the disclosing party
                    with an opportunity to make representations to the relevant
                    court or governmental or regulatory body.

     10.5. For the avoidance of doubt, information shall not be deemed to be
           within any of the exceptions included in Clause 10.4 merely because
           it is embraced by general disclosure in the public domain or in the
           lawful possession of the receiving party, nor shall a combination of
           information be deemed to be within any of the exceptions set out in

           public domain or in the lawful possession of the receiving party,
           unless the specific combination of information is itself in the
           public domain or in the lawful possession of the receiving party.

                    acts and/or omissions of each Sub-Licensee as if such acts
                    or omissions had been made by the Licensee;

<PAGE>
 
           11.4.4.  the Licensee shall use its reasonable endeavours to procure
                    that each Sub-Licensee complies fully at all times with the
                    provisions of its sub-licence agreement in respect of the
                    subject matter hereof and shall enforce the terms of each

           or hindrance in obtaining any raw materials, energy or other cause
           beyond the control of either party. If either party is unable to
           perform its duties and obligations under this Agreement as a direct
           result of the effect of one or more of such causes such party shall
           give written notice to the other of such inability stating the cause
           in question and the date on which such cause commenced. The operation
           of this Agreement shall be suspended during the period (and only
           during the period) in which the cause continues to have effect.
           Forthwith upon the cause ceasing to have effect the party relying
           upon it shall give written notice thereof to the other. If the cause
           continues to have effect for a period of more than 60 days the party
           not claiming relief under this clause shall have the right to
           terminate this Agreement upon giving 30 days written notice of such
           termination to the other party, but such notice shall not take effect
           if the other party gives notice within that period that the cause has
           ceased to prevent the operation of this Agreement and forthwith upon

13.  ILLEGALITY
     ----------

     13.1. If any provision or term of this Agreement shall become or be
           declared illegal, invalid or unenforceable for any reason whatsoever

           shall be deemed to be deleted from this Agreement provided always
           that if such deletion substantially affects or alters the commercial
           basis of this Agreement the parties shall negotiate in good faith to
           amend and modify the provisions and terms of this Agreement so as to
           achieve so far as possible the same economic effect without rendering

14.  ENTIRE AGREEMENT/AMENDMENT/PRESS RELEASES/COSTS
     -----------------------------------------------

     14.1. This Agreement constitutes the entire agreement and understanding of

           matter of this Agreement. Neither party shall be entitled to rely on
           any agreement, understanding, or arrangement, representation, term or
           warranty which is not expressly contained in this Agreement and no
           change may be made to it except in writing signed by duly authorised
           representatives of both parties save that nothing in this Agreement
           shall operate to exclude any provision implied into this Agreement by
           English law which may not be excluded by English law or to limit or
           exclude any liability, right or remedy to a greater extent than is
           permissible under English law.

     14.2. Without prejudice to the generality of Clause 14.1, the Licensor does
           not give any warranty, representation or undertaking:-

           14.2.2.  that any of the Patents is or will be valid or subsisting or
                    where any such Patents are applications that, such
                    applications will proceed to grant; or

           14.2.3.  that any use of the Intellectual Property and the
                    manufacture, supply or use of any of the Products will not

                    third party.

     14.3. No failure or delay on the part of either of the parties to exercise
           any right or remedy under this Agreement shall be construed or
           operate as a waiver thereof nor shall any single or partial exercise
           of any right or remedy preclude the further exercise of such right or
           remedy as the case may be. The rights and remedies provided in this
           Agreement are cumulative and are not exclusive of any rights or
           remedies provided by law.

     14.4. The text of any press release or other communication to be published
           by or in the media concerning the subject matter of this Agreement
           shall require the approval of each of the parties.

     14.5. Each of the parties shall be responsible for its respective legal and
           other costs incurred in relation to the preparation of this
           Agreement. 

     14.6. Nothing in this Agreement shall create or imply any relationship of
