Note 1. Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information and in accordance with instructions to Article 10 of
Regulation S-X. Accordingly, such consolidated financial statements do not
include all of the information and disclosures required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.

The operating results of the interim periods presented are not necessarily
indicative of the results to be achieved for the year ending December 31, 1999.
The accompanying consolidated financial statements should be read in conjunction
with the audited financial statements and notes thereto for the year ended
December 31, 1998 included in the Company's 1998 Annual Report on Form 10-K
filed with the Securities and Exchange Commission ("SEC").

The consolidated financial statements include the accounts of Novoste
Corporation and its wholly-owned subsidiaries incorporated in August 1998 in The
Netherlands, in December 1998 in Belgium and February 1999 in Germany.
Significant intercompany transactions and accounts have been eliminated.

Note 2. Inventories

Inventories are stated at the lower of cost or market. Inventories are comprised
of the following at September 30, 1999:

                                     September 30, 1999    December 31, 1998

                                     ==================    =================

Note 3. Net Loss Per Share

The basic and diluted loss per share is computed based on the weighted average
number of common shares outstanding. Common equivalent shares are not included
in the per share calculations where the effect of their inclusion would be
antidilutive.

Note 4. Cash Equivalents and Investments

Cash equivalents are comprised of certain highly liquid investments with
maturities of less than three months at the time of their acquisition. In
addition to cash equivalents, we have investments in commercial paper that are
classified as short-term (mature in more than 90 days but less than one year).
Management determines the appropriate classification of debt securities at the
time of purchase and reevaluates such designation as of each balance sheet date.
Debt securities are classified as held-to-maturity when the Company has the
positive intent and ability to hold the securities to maturity. Investments
held-to-maturity are carried at amortized cost, adjusted for the amortization or
accretion of premiums or discounts without recognition of gains or losses that
are deemed to be temporary. Premiums and discounts are amortized or accreted
over the life of the related instrument as an adjustment to yield


                                       6
<PAGE>

using the straight-line method, which approximates the effective interest
method. Interest income is recognized when earned.

Marketable equity securities and debt securities not classified as
held-to-maturity are classified as available-for-sale. Available-for-sale
securities are carried at fair value, with the unrealized gains and losses
reported in a separate component of shareholders' equity, if significant. The
amortized cost of debt securities in this category is adjusted for amortization
of premiums and accretion of discounts to maturity. Such amortization is
included in investment income. Realized gains and losses and declines in value
judged to be other-than-temporary on available-for-sale securities are included
in investment income. The cost of securities sold is based on the specific
identification method. Interest and dividends on securities classified as
available-for-sale are included in investment income. At September 30, 1999 fair
value approximated net book value for all short-term investments.

Note 5. Revenue Recognition

Revenues from sales of products are recognized at the time of shipment with
allowances provided for estimated returns, warranty costs and doubtful accounts.

Note 6. Consulting Agreements

On May 13, 1999 the Company granted stock options to the members of its Clinical
Advisory Board. These options were priced at the fair market value on the date
of grant and the related consulting expense will be recognized over the one-year
vesting period.

Note 7. Follow-on Equity Offering

On March 19, 1999 the Company completed a follow-on equity offering (the
"Offering") of 2,400,000 newly issued shares of its common stock at a public
offering price of $20 per share. On March 24, 1999 the Company issued an
additional 160,000 shares of common stock pursuant to the exercise of the
underwriters' over-allotment option. Net proceeds to the Company after the
exercise of the underwriters' over-allotment option and all related expenses
approximated $47.5 million.

Overview

Novoste commenced operations as a medical device company in May 1992. Since
1994, we have devoted substantially all of our efforts to developing the
Beta-CathTM System, an intraluminal beta radiation catheter delivery system
designed to reduce the frequency of restenosis subsequent to percutaneous
transluminal coronary angioplasty ("PTCA") as well as other interventional
procedures.

For the period since our capitalization through December 31, 1998 we earned
minimal non-recurring revenues and experienced significant losses in each
period. The Company commenced the active marketing of the Beta-CathTM System in
Europe in January 1999. At September 30, 1999 we had an accumulated deficit of
approximately $75.8 million. We expect to continue to incur significant
operating losses through at least 2000 as we conduct clinical trials, seek
regulatory approval or clearance for our products, continue research and
development projects, expand our sales and marketing efforts in contemplation of
product introduction and market development, and increase our administrative
activities to support our growth.

The clinical trials may not demonstrate the safety and efficacy of the Beta-Cath
System. Additionally, we may not obtain necessary approvals for the Beta-Cath
System from the FDA, the State of Georgia Department of Natural Resources or
other state or foreign governmental agencies. Our research and development
efforts may not be successfully completed. We may not successfully introduce the
Beta-Cath System or attract any significant level of market acceptance for the
Beta-Cath System or any other product we develop. We may never achieve
significant revenues from sales of our Beta-Cath System and we may never achieve
or sustain profitability.

Clinical Trials

We are currently conducting two pivotal clinical trials, the Beta-Cath System
Trial and the START Trial as well as several other trials. The pivotal trials
are intended to support a pre-market approval application to the FDA to market
our device in the United States to reduce the incidence of coronary restenosis
following PTCA, stent placement and the treatment of "in-stent" restenosis.

The Beta-Cath System Trial. On July 30, 1997 we initiated our Beta-Cath System
Trial, a randomized, triple-masked, placebo-controlled, multicenter human
clinical trial under an investigational device


                                       8
<PAGE>

exemption granted by the FDA. The Beta-Cath System Trial seeks to determine the
clinical safety and effectiveness of the Beta-Cath System in reducing coronary
restenosis following PTCA or stent placement. We initially targeted enrollment
for approximately 1,100 patients in the trial at up to 55 clinical sites located
in the United States. The protocol contemplated that patients would be divided
into two approximately equal subgroups, one receiving PTCA alone and one
receiving coronary stents in addition to PTCA.

Patients in each subgroup of the trial received, determined on a random basis,
either vascular brachytherapy through the Beta-Cath System using a 30mm
radiation source train or no vascular brachytherapy through a placebo version of
the Beta-Cath System. In both subgroups, patients who received the beta
radiation received dosages of 14 gray for vessels ranging from 2.70 to 3.35mm
and 18 gray for vessels ranging from 3.36 to 4.00mm. The protocol provides for
telephone follow-up with patients 30 days after treatment for PTCA patients and
monthly for newly stented patients up to the eighth month, and a follow-up
angiogram eight months after the initial treatment regardless of the treatment.
The primary endpoint of the trial is target vessel revascularization ("TVR"),
the incidence of an additional revascularization procedure in the vessel
originally treated within eight months. Other endpoints of the trial include
angiographic restenosis, late loss index, and the incidence of major adverse
cardiac events.

As is typical for patients undergoing stent placement, the patients in the stent
placement subgroup of the Beta-Cath System Trial received anti-platelet therapy
to prevent stent thrombosis, a condition which can lead to acute closure of the
treated artery. Stent thrombosis typically occurs within 30 days of treatment in
a small percentage of patients receiving stent placement. There were incidences
of stent thrombosis reported in the Beta-Cath System Trial. These patients
developed the condition later following their treatment than is normally
observed. As a result, in November 1998 we modified the Trial protocol for the
stent placement subgroup to extend the anti-platelet therapy from two weeks to
60 days following stent placement and to provide for additional follow-up
contact with these patients in the second, third and fourth months after
treatment. On April 27, 1999 we announced approval of our intention to increase
patient enrollment in the stent placement subgroup of the Trial and to extend
the anti-platelet therapy to a minimum of 90 days following stent placement.
These changes were made based upon a recommendation made by the Data Safety and
Monitoring Board (DSMB) at its March 1999 meeting. The DSMB is an independent
committee of clinicians and statisticians that has responsibility for review of
the study protocol and clinical events at regular intervals during patient
enrollment into the Trial. Based on its review of the available data set,
including the incidence of major adverse cardiac events, the DSMB proposed these
changes to ensure sufficient data to evaluate the safety and effectiveness of
the Beta-Cath System with the revised anti-platelet therapy protocol. We
completed enrollment in the PTCA subgroup in July 1999 and enrollment in the
stent placement subgroup with the extended antiplatelet therapy in September
1999. Enrollment in the Trial was stopped on September 30, 1999 after having
enrolled a total of 1,456 patients at 58 clinical sites, principally located in
the United States. A follow-up angiogram eight months after the initial
treatment will be performed to observe the treated artery. The angiogram will be
analyzed to determine if there has been an incidence of restenosis and to
measure late loss index.

The START Trial. On September 21, 1998 we initiated the "STents And Radiation
Therapy Trial" or START Trial, a randomized, triple-masked, placebo-controlled,
multicenter human clinical trial, under an investigational device exemption
granted by the FDA. The primary endpoint of this trial is target vessel
revascularization within eight months of treatment. The START Trial seeks to
determine the safety and effectiveness of the Beta-Cath System in treating
"in-stent" restenosis. We divided patients into two approximately equal
subgroups, one receiving vascular brachytherapy through the Beta-Cath System
using a 30mm radiation source train and the other receiving no vascular
brachytherapy through a placebo version of the Beta-Cath System. Patients who
received the beta radiation received dosages of 16 gray for vessels ranging from
2.70 to 3.35mm and 20 gray for vessels ranging from 3.36 to 4.00mm, slightly
higher doses than those used in our Beta-Cath System Trial because of radiation
shielding from stents


                                       9
<PAGE>

previously implanted in a procedure unrelated to this trial. Although the START
Trial protocol does not contemplate the placement of new stents, we believe that
approximately 20% of the enrolled patients received new stents. We surpassed our
targeted enrollment of 386 patients, and enrollment in this trial was completed
as of April 30, 1999. A total of 476 patients were enrolled at 51 sites, located
principally in the United States. A follow-up angiogram eight months after the
initial treatment will be performed to observe the treated artery. The angiogram
will be analyzed to determine if there has been an incidence of restenosis and
to measure late loss index.

We do not anticipate FDA approval to market the Beta-Cath System in the United
States for any indication any earlier than one year after the FDA accepts our
application for filing. Assuming the START Trial yields positive results, we
expect that our application seeking approval to market the Beta-Cath System in
the United States to treat "in-stent" restenosis will be submitted to the FDA
first and will be based upon the enrollment of 476 patients in that Trial.

The START 40 Trial. In addition, on June 22, 1999 we initiated the START 40
Trial. This multicenter clinical trial has a targeted enrollment of 200 patients
who will receive vascular brachytherapy using a 40 mm active radiation source
train. The START 40 Trial has an identical clinical design to the START Trial
and, therefore, we will use the START Trial's control group in analyzing the
clinical data from the START 40 Trial. The purpose of this trial is to gain
regulatory approval for the longer, 40mm radiation source train. Enrollment in
this trial of the planned 200 patients was completed on October 22, 1999.

BRIE Trial. We are currently conducting a 180 patient multicenter,
non-randomized registry trial in Europe, known as the BRIE trial. This registry
started in July 1998 and is intended to enhance market acceptance of the
Beta-Cath System among physicians and to collect additional clinical data to
support reimbursement approvals. As of October 22, 1999, 171 patients had been
enrolled at nine sites. We reported interim clinical results on August 31, 1999
for the first 90 patients who returned for angiographic follow-up. These
patients were all enrolled prior to the aforementioned extension of
anti-platelet therapy to a minimum of 90 days. The independent core lab provided
the following data:

                                                 PTCA       Stent       Total
                                               Subgroup   Subgroup   Population
   -----------------------------------------------------------------------------
   NUMBER OF LESIONS                              36         62          98
   Restenosis - Initial Obstructed Segment(1)      8%        16%         13%
   Late Loss Index                                 3%        17%         12%
   -----------------------------------------------------------------------------

   (1) For purposes of the interim analysis, the core lab approximated the
   target lesion by analyzing the "initial obstructed segment" of the artery,
   a 5mm or 10mm segment containing the minimum lumen diameter (MLD).
   Restenosis was calculated using the MLD of this segment as compared to the
   interpolated reference vessel diameter at follow-up.

The core lab also provided angiographic data on a broader vessel segment (beyond
the target lesion) to determine if there were cases where the radiation source
train did not adequately cover the arterial segment revascularized by balloon
angioplasty or stent placement, a concept known as "geographic miss". Geographic
miss often reduces the effectiveness of radiation because the target tissue is
insufficiently dosed. This broader variable of Target Vessel Restenosis was
measured with and without late coronary occlusion, an event observed in earlier
vascular brachytherapy trials in a small percentage of stent patients, before
the need for extended anti-platelet therapy (APT) was understood. None of the
patients included in the interim BRIE data analysis received an extended APT
regimen due to the timing of their


                                       10

enrollment. The broader data set is as follows:

Results of Operations

Net loss for the three months ended September 30, 1999 was $8,066,270, or ($.57)
per share, as compared to $6,805,743 or ($.64) per share, for the three months
ended September 30, 1998. Net loss for the nine months ended September 30, 1999
was $23,566,544 or ($1.79) per share as compared to $15,429,585 or ($1.47) per
share for the year earlier period. The increase in net loss for the three and
nine months ended September 30, 1999 compared to the year earlier period was
primarily due to increased research and development spending related to the
company's clinical trials and product development activities and increased sales
and marketing spending related to the commercial launch of the Beta-Cath System
in Europe.

Net Sales. Net sales of $566,872 were recognized in the three months ended
September 30, 1999. Net sales of $1,204,699 were recognized for the nine months
ended September 30, 1999. No revenues were earned for the three and nine months
ended September 30, 1998. The Company expects net sales to increase in the
future as direct distribution is expanded in Europe, and if and when the
Beta-Cath System is approved by the FDA and launched commercially in the U.S.

Cost of Sales. Cost of sales of $539,777 were incurred in the three months ended
September 30, 1999 and $1,216,943 for the nine months ended September 30, 1999.
No cost of sales were incurred for the three and nine months ended September 30,
1998. The Company expects cost of sales to closely approximate sales for the
year ended 1999 as the Company ramps up both its European production and sales
activities.

Research and Development Expenses. Research and development expenses increased
8% to $6,115,556 for the three months ended September 30, 1999 from $5,685,268
for the three months ended September 30, 1998. For the nine months ended
September 30, 1999 research and development expenses increased 32% to
$17,950,943 from $13,597,906 for the same period in 1998. These increases were
primarily the result of patient enrollment and follow-up costs in the Company's
clinical trials, the cost of supplying the Beta-Cath System to clinical sites,
and costs related to the ongoing development of the Beta-Cath System.

Sales and Marketing Expenses. Sales and marketing expenses increased 202% to
$1,678,437 for the three months ended September 30, 1999 from $832,230 for the
three months ended September 30, 1998. For the nine months ended September 30,
1999 sales and marketing expenses increased 265% to $4,519,703 from $1,703,656
for the same period in 1998. These increases were primarily the result of higher
personnel, trade show, consulting and promotional literature costs associated
with marketing the Company's product on a direct basis in Europe. The Company
expects sales and marketing expenses to increase significantly in the future as
direct distribution is expanded in Europe, and if and when the Beta-Cath System
is approved by the FDA and launched commercially in the U.S.

General and Administrative Expenses. General and administrative expenses
increased 15% to $917,379 for the three months ended September 30, 1999 from
$799,805 for the three months ended September 30, 1998. For the nine months
ended September 30, 1999 general and administrative expenses increased 47% to
$2,731,284 from $1,852,670 for the same period in 1998. This increase for the
three and nine month periods was primarily the result of additional management
personnel and higher salaries. The Company


                                       11
<PAGE>

expects general and administrative expenses to increase in the future in support
of a higher level of operations.

Interest Income. Net interest income increased 21% to $618,007 for the three
months ended September 30, 1999 from $511,560 for the three months ended
September 30, 1998. For the nine months ended September 30, 1999 interest income
decreased 5% to $1,647,630 from $1,724,647. The increase in interest income for
the quarter was primarily due to the increase in average cash equivalent and
short-term investment balances arising from the follow-on public offering
completed in March 1999.

Liquidity and Capital Resources

During the nine months ended September 30, 1999 and 1998 the Company used cash
to fund operations of $23.9 million and $13.4 million, respectively. The
increase in cash used in operations was due primarily to increased research and
development activities and the expansion of sales and marketing activities in
Europe. At September 30, 1999 the Company had commitments to purchase $3.2
million in inventory components of the Beta-Cath System over the next year. In
addition, on October 14, 1999 the Company signed a development and manufacturing
supply agreement with AEA Technologies QSA GmbH for a second source of
radioisotope supply and for the development of a smaller diameter source. This
agreement provides for the construction of a production line over the period
October 1, 1999 to February 2001. The cost of this production line is estimated
at $4,000,000 and will be paid by the Company as construction progresses.
Because of the development, manufacturing scale-up and commercialization of the
Beta-Cath System, Novoste's future cash needs for operating and investing
activities are anticipated to be higher than historical levels subject to the
factors discussed below.

On March 19, 1999 the Company completed a follow-on public offering of 2,400,000
newly issued shares of its common stock at a public offering price of $20 per
share. On March 24, 1999 the Company issued an additional 160,000 shares of
common stock pursuant to the exercise of the underwriters' over-allotment
option. Net proceeds to the Company after the exercise of the underwriters'
over-allotment option and all related expenses totaled $47.5 million.

The Company's principal source of liquidity at September 30, 1999 consisted of
cash, cash equivalents and short-term investments of $48.6 million. The Company
did not have any credit lines available or outstanding borrowings at September
30, 1999.

The Company anticipates that its operating losses will continue through at least
2000 as it expends substantial resources in funding clinical trials in support
of regulatory approvals, and continues to expand research and development and
sales and marketing activities. We believe that our existing capital resources
will be sufficient to fund the company through the end of 2000, but those
resources may prove insufficient. We cannot assure that additional financing, if
required, will be available on satisfactory terms, or at all. However, the
Company's future liquidity and capital requirements will depend upon numerous
factors, including, among others: the progress of the Company's clinical
research and product development programs; the receipt of and the time required
to obtain regulatory clearances and approvals; the resources required to gain
approvals; the resources the Company devotes to the development, manufacture and
marketing of its products; the resources required to hire and develop a direct
sales force in the United States and in the larger markets of Europe, develop
distributors internationally, and to expand manufacturing capacity; and market
acceptance and demand for its products. Additional capital may be required to
launch the Beta-Cath System in the United States. Novoste may in the future seek
to raise additional funds through bank facilities, debt or equity offerings or
other sources of capital. There can be no assurance that additional financing,
if required, will be available on satisfactory terms, or at all.


                                       12

Impact of Year 2000

We have completed the process of evaluating the potential impact of what is
commonly referred to as the year 2000 issue, concerning the inability of certain
computer systems to properly recognize and process dates starting with the year
2000 and beyond. We are taking steps to ensure that our business systems
software and equipment will continue to function properly after December 31,
1999. In doing so, we have established a team, which is working directly with
management to (1) assess and test all internal information systems and other
systems that may be affected by the year 2000 date change; (2) assess and test
our products that may be affected by the year 2000 date change; (3) communicate
with third parties that supply our products to ensure they are addressing the
year 2000 issue; and (4) compose a contingency and disaster recovery plan to
ensure resolution of problems that may arise as a result of the year 2000 date
change.

As of September 30, 1999 items (1), (2), (3) and (4) above are complete. Because
the Company is relying on information provided to it by third parties to assess
the Year 2000 readiness of such vendors, the Company cannot provide assurances
that all of its critical vendors are or will be Year 2000 ready. As a
contingency, the Company has increased safety stock levels on its critical
component inventory.

The Beta-Cath System does not contain any real time clocks and therefore the
device itself does not present any year 2000 issues.

With respect to our internal business systems, an assessment of equipment and
software was started in September 1998. In addition, in anticipation of in-house
manufacturing, we purchased a complete manufacturing software package in January
1998 that includes integrated financial modules that replace our previous
financial software program. The contract for the purchase of the new software
package requires year 2000 compliance. We have completed testing to determine
that our internal systems are year 2000 compliant. All internal systems critical
to the Company's overall business have been inventoried and evaluated. As of
September 30, 1999, 90% of the Company's internal systems have been determined
to be year 2000 compliant or where upgraded and are now year 2000 compliant. The
remaining 10% of the Company's internal systems are ether slated for
obsolescence by or before December 31, 1999 or will be upgraded by October 31,
1999.

We have and will continue to devote the necessary resources to resolve all
significant year 2000 issues in a timely manner. Based upon current estimates,
we expect capital expenditures of approximately $100,000 will be necessary to
achieve year 2000 compliance. As of September 30, 1999 the Company has expended
approximately $60,000 for year 2000 compliance.

Regardless of the year 2000 compliance of our systems and products, we may be
adversely affected by disruptions in the operations of the enterprises with
which we interact. These business enterprises include suppliers, clinical
research organizations, corporate partners, both domestic and international,
government agencies, hospitals, physicians and other third parties. We cannot
reasonably predict the impact on our operations and financial condition if any
such businesses are adversely affected by the year 2000 issue.

Statements made herein about the implementation of various phases of our year
2000 program, the costs expected to be associated with that program and the
results we expect to achieve constitute forward-looking information. There are
many uncertainties involved in the year 2000 issue and the following important
factors, among others, could affect the impact of the year 2000 issue: (1) the
inherent uncertainty of the costs and timing of achieving compliance on the wide
variety of systems used by us, (2) the reliance on the efforts of vendors,
customers, government agencies and other third parties beyond our control to
achieve adequate compliance and avoid disruption of our business in early 2000
and (3) the


                                       13
<PAGE>

uncertainty of the ultimate costs and consequences of any unanticipated
disruption of our business resulting from the failure of one of our applications
or of a third party's systems.

CERTAIN FACTORS THAT MAY IMPACT FUTURE OPERATIONS

Dependence On The Successful Development And Commercialization Of The Beta-Cath
System

We have not yet successfully commercialized any product in the United States and
only started to sell the Beta-Cath System in Europe in December 1998. We
anticipate that for the foreseeable future we will be solely dependent on the
successful development and commercialization of the Beta-Cath System. Failure to
commercialize the Beta-Cath System would have a material adverse effect on our
business, financial condition and results of operations.

The Beta-Cath System will require further development and clinical testing, as
well as regulatory approval, before we can market it in the United States. Our
development efforts and clinical testing may not be successful.

Commercialization of the Beta-Cath System in Europe is subject to certain
additional risks. Physicians in Europe are generally less receptive to and
slower to adopt new medical devices and technologies than physicians in the
United States due to various factors. These factors include the influence of
national health care policies and reimbursement strategies of health care payors
and the frequent absence of pivotal human clinical trial results at the time a
manufacturer qualifies to apply the CE marking to a new medical device and
commences sale of the device. We may never achieve significant revenue from
sales in Europe or ever achieve or sustain profitability in our European
operations.

Limited Operating History; History Of Losses And Expectation Of Future Losses
Through At Least The Year 2000

We have a limited history of operations. Since our inception in May 1992, we
have been primarily engaged in developing and testing our Beta-Cath System. We
have generated only limited revenue and do not have experience in manufacturing,
marketing or selling our products in quantities necessary for achieving
profitability.

At September 30, 1999 we had accumulated a deficit of approximately $75.8
million since our inception in 1992. The commercialization of the Beta-Cath
System and other new products, if any, will require substantial additional
development, clinical, regulatory, manufacturing, sales and marketing and other
expenditures. We expect our operating losses to continue through at least 2000
as we continue to expand our product development, clinical trials and marketing
efforts. We may never commercialize the Beta-Cath System, or any other product,
or achieve or sustain profitability.

Clinical Testing Of Beta-Cath System; No Assurance Of Its Safety And
Effectiveness

The safety and effectiveness of the Beta-Cath System has not been determined in
a placebo-controlled, pivotal trial. We are currently conducting two
multi-center human clinical trials of the Beta-Cath System to determine its
safety and effectiveness. At September 30, 1999 we completed enrollment in both
the PTCA and stent placement subgroup of the Beta-Cath System Trial and had
enrolled a total of 1,456 patients at 58 clinical sites. We completed enrollment
in the START Trial in April 1999, having enrolled 476 patients at 51 sites,
principally located in the United States.

As is typical for patients receiving stent placement, the patients in the stent
placement subgroup of the Beta-Cath System Trial receive anti-platelet therapy
to prevent stent thrombosis, a condition which can


                                       14
<PAGE>

lead to acute closure of the treated artery. Stent thrombosis typically occurs
within 30 days of treatment in a small percentage of patients receiving stent
placement. There were incidences of stent thrombosis reported in the Beta-Cath
System Trial. These patients developed the condition later following their
treatment than is normally observed. As a result, in November 1998, we modified
the Trial protocol for the stent placement subgroup to extend the anti-platelet
therapy from two weeks to 60 days following stent placement and to provide for
additional follow-up contact with these patients in the second, third and fourth
months after treatment. On April 27, 1999 we announced approval of our intention
to increase patient enrollment in the stent placement subgroup of the Trial by
up to 300 more patients and to extend the anti-platelet therapy to a minimum of
90 days following stent placement. These changes were made based upon a
recommendation made by the Data Safety and Monitoring Board (DSMB) at its March
1999 meeting. Based on its review of the available data set, including the
incidence of major adverse cardiac events, the DSMB proposed these changes to
ensure sufficient data to evaluate the safety and effectiveness of the Beta-Cath
System with the revised anti-platelet therapy protocol.

Both of our current pivotal trials require follow-up examinations with patients
after eight months. It is only after analysis of a statistically significant
number of patients in one of these trials that we would apply for the regulatory
approvals required to commence marketing the Beta-Cath System in the United
States. Various factors, including performing follow-up examinations on
patients, could delay completion of either trial for an indeterminate amount of
time. The data from these trials, if completed, may not demonstrate the safety
and effectiveness of the Beta-Cath System and may not be adequate to support our
application to the FDA for pre-market approval. In particular, we cannot be sure
that the incidence of stent thrombosis seen in the Beta-Cath System Trial will
be resolved by the protocol modification. If the Beta-Cath System does not prove
to be safe and effective in clinical trials, our business, financial condition
and results of operations will be materially adversely affected. In addition,
the clinical trials may identify significant technical or other obstacles to
obtaining necessary regulatory approvals. Because vascular brachytherapy in
human coronary arteries is a relatively new treatment, the long-term effects on
patients are not known and likely will not be known for several years. As a
result, even if our current clinical trials indicate the Beta-Cath System is
safe and effective over an eight-month period, we cannot be sure that the
Beta-Cath System will be safe and effective over the long term.

No Assurance of Regulatory Approvals

United States Pre-Market Approvals.

We will not be able to commence marketing or commercial sales of the Beta-Cath
System in the United States unless we receive pre-market approval from the FDA.
We do not expect to submit a pre-market approval application until the second
quarter of 2000 at the earliest, following analysis of a statistically
significant number of patients in the START Trial.

We do not anticipate FDA approval to market the Beta-Cath System in the United
States for any indication any earlier than one year after the FDA accepts our
application for filing. Assuming the START Trial yields positive results, we
expect that our application seeking approval to market the Beta-Cath System in
the United States to treat "in-stent" restenosis will be submitted to the FDA
first and will be based upon the enrollment of 476 patients in that Trial. The
FDA could require that we submit results from our Beta-Cath System Trial prior
to considering our initial application for approval of our device in treating
"in-stent" restenosis. Instead of filing an additional, separate application, we
may amend our initial application relating to "in-stent" restenosis to seek
pre-market approval of the Beta-Cath System for use following PTCA and stent
placement based upon the results of the Beta-Cath System Trial. If we file such
an amendment, the FDA would restart the statutory review period for our initial
application as of the date of the filing of the amendment. This would cause a
delay in obtaining FDA approval. Moreover, if either Trial does not yield
positive results, the FDA's consideration of any application we have submitted
could be adversely affected; any such application could be refused filing for
substantive review, or if filed,


                                       15
<PAGE>

could be subject to requests for substantial amounts of additional information,
or ultimately could be denied approval.

The FDA may request additional data or require that we conduct further clinical
trials, either of which could delay or preclude our receipt of pre-market
approval as well as require significant additional expenditures. Such a delay or
failure to receive pre-market approval would have a material adverse effect on
our business, financial condition and results of operations and could result in
cessation of our operations. Even if we receive approval based on the results of
the START Trial, we will be limited to marketing the Beta-Cath System for use
with patients who are being treated for "in-stent" restenosis in a single
coronary artery. In order to market the Beta-Cath System for a broader range of
patients, we will seek to expand the indications for which the Beta-Cath System
can be marketed to include patients receiving PTCA or stent placement. Even if
we receive approval based on the results of the Beta-Cath System Trial, we would
be limited to marketing the Beta-Cath System for use with patients who are being
treated for one lesion in a single coronary artery following PTCA or stent
placement. In order to market the Beta-Cath System for use with a broader range
of patients, we will likely be required to demonstrate to the FDA through
additional clinical trials that the Beta-Cath System is safe and effective in
treating a broader range of indications and the FDA must approve a pre-market
approval application, application amendment or application supplement covering
the broader range of indications for the device.

Foreign Pre-Market Approvals.

Sales of the Beta-Cath System outside the United States are subject to
regulatory requirements that vary widely from country to country but generally
include pre-marketing governmental approval. The time required to obtain
approval for sale in foreign countries may be longer or shorter than required
for FDA approval, and the requirements for the conduct of clinical trials,
marketing authorization, pricing and reimbursement differ from those in the
United States. Moreover, the export of medical devices from the United States
must be in compliance with FDA regulations. In August 1998 we qualified to apply
CE marking to the Beta-Cath System, a requirement necessary to sell our device
in most of Western Europe. We are subject to continuing audit and reporting
requirements related to this marking. We may be delayed or precluded from
marketing the Beta-Cath System in other foreign countries. Foreign pre-market
and other regulatory approvals of the Beta-Cath System, if granted, may include
significant limitations on the indicated uses for which the device may be
marketed.

Approvals to Use, Handle and Transfer Radioactive Materials.

Our business involves the import, manufacture, transfer, use and disposal of
Strontium 90 (Strontium/Yttrium), the beta-emitting radioisotope utilized in the
Beta-Cath System's radiation source train. Accordingly, manufacture,
distribution, use and disposal of the radioactive material used in the Beta-Cath
System in the United States will be subject to federal, state and/or local laws
and regulations relating to the use and handling of radioactive materials.
Specifically, we must obtain approval from the State of Georgia Department of
Natural Resources to commercially distribute our radiation sources to licensed
recipients in the United States. In addition, we must also comply with NRC,
Georgia and United States Department of Transportation regulations on the
labeling and packaging requirements for shipment of radiation sources to
hospitals or other users of the Beta-Cath System. Further, hospitals and/or
physicians in the United States may be required to amend their radiation
licenses to hold, handle and use Strontium 90 prior to receiving and using our
Beta-Cath System.

The distribution and use of the Beta-Cath System outside the United States is
subject to radiation regulatory requirements that vary from country to country
and sometimes vary within a given country. Generally, each country has a
national regulatory agency responsible for regulating the safe practice and use
of radiation in its jurisdiction. In addition, each hospital desiring to use the
Beta-Cath System is generally required to amend its license to store, handle and
receive the Strontium 90 sources in our device. Generally, these licenses are
specific to the amount and type of radioactivity utilized. In addition,


                                       16
<PAGE>

generally the use of a radiation source by a physician, either for a diagnostic
or therapeutic application, also requires a license, which again is specific to
the isotope and the clinical application.

Obtaining any of the foregoing radiation-related approvals and licenses can be
complicated and time consuming. If we or any hospital or physician is
significantly delayed in obtaining any of the foregoing approvals or any of
those approvals are not obtained, our business, financial condition and results
of operations could be materially adversely affected.

Risk Of Inadequate Funding

We anticipate that our losses will continue through at least the year 2000 as we
expend substantial resources to fund clinical trials in support of regulatory
approvals, continue development of the Beta-Cath System and launch our product
first in Europe and then in the United States. Our future liquidity and capital
requirements will depend upon numerous factors.

We believe that our existing capital resources will be sufficient to fund the
company through the end of 2000, but those resources may prove insufficient.
Additional capital may be required to launch the Beta-Cath System in the United
States. We may in the future seek to raise additional funds through bank
facilities, debt or equity offerings or other sources of capital. We cannot
assure that additional financing, if required, will be available on satisfactory
terms, or at all.

Rapid Technological Change And Intense Competition

Competition in the medical device industry, and specifically the markets for
cardiovascular devices, is intense and characterized by extensive research and
development efforts and rapidly advancing technology. New developments in
technology could render vascular brachytherapy generally or the Beta-Cath System
in particular noncompetitive or obsolete.

Vascular brachytherapy may compete with other treatment methods designed to
improve outcomes from coronary artery procedures that are well established in
the medical community, such as coronary stents. Stents are the predominant
treatment currently utilized to reduce the incidence of coronary restenosis
following PTCA and were used in approximately 60% of all PTCA procedures
performed worldwide in 1998. Manufacturers of stents include Johnson &
Johnson/Cordis, Medtronic, Inc., Guidant Corporation and Boston Scientific
Corporation. Stent manufacturers often sell many products used in the cardiac
catheterization labs, commonly referred to as cath labs, and as discussed below
certain of these companies are developing vascular brachytherapy devices.

      Other devices under development that use vascular brachytherapy include:

      o     a radioactive-tipped guidewire;
      o     a radioactive stent; and
      o     a radioactive fluid-filled balloon.

The most advanced competitive approach may be represented by the radioactive
guidewire, as we are aware that Johnson & Johnson/Cordis and Guidant are
investigating this general type of device in the pivotal clinical trial stage in
the United States. Many of our competitors and potential competitors have
substantially greater capital resources than we do and also have greater
resources and expertise in the areas of research and development, obtaining
regulatory approvals, manufacturing and marketing. We cannot assure you that
competitors and potential competitors will not succeed in developing, marketing
and distributing technologies and products that are more effective than those we
will develop and market or that would render our Beta-Cath System obsolete or
noncompetitive. Additionally, many of the


                                       17
<PAGE>

competitors have the capability to bundle a wide variety of products in sales to
cath labs. We may be unable to compete effectively against such competitors and
other potential competitors in terms of manufacturing, marketing and sales.

Any product we develop that gains regulatory clearance or approval will have to
compete for market acceptance and market share. An important factor in such
competition may be the timing of market introduction of competitive products.
Accordingly, we expect the relative speed with which we can develop products,
gain regulatory approval and reimbursement acceptance and supply commercial
quantities of the product to the market to be an important competitive factor.
One of our competitors, Johnson & Johnson/Cordis, has recently submitted a
pre-market approval application to the FDA for its gamma-emitting vascular
brachytherapy device. Other manufacturers may be the first to market a vascular
brachytherapy system to reduce the incidence of restenosis in the United States.
We may also not be the first to market a beta-emitting vascular brachytherapy
system in the United States or be able to market such a system effectively.

Limitations On Third-Party Reimbursement For The Beta-Cath System

The Beta-Cath System, where approved for commercial sale, will be sold primarily
to hospitals. Hospitals and physicians bill various third-party payors, such as
government health programs, private health insurance plans, managed care
organizations and other similar programs, for the health care services provided
to their patients.

If and when we receive FDA approval to market the Beta-Cath System in the United
States, third-party payors may not cover procedures using the Beta-Cath System
or, if covered, third-party payors may place certain restrictions on the
circumstances in which coverage will be available. In addition, payors may deny
reimbursement if they determine a product was not used in accordance with
established payor protocol regarding cost-effective treatment methods or was
used for an unapproved indication. Third-party payors are increasingly
challenging the prices charged for medical products and services and, in some
instances, have put pressure on medical device suppliers and health care
providers to lower their prices. We are unable to predict what changes
third-party health care payors will make in their reimbursement methodologies.
Third-party payors or health care providers may not consider the Beta-Cath
System cost-effective and may not reimburse for its usage or, if they do, may
reimburse at levels that adversely affect its market acceptance and our ability
to sell the Beta-Cath System on a profitable basis.

The cost of health care has risen significantly over the past decade, and
legislators, regulators, third-party payors and health care providers have made
and may continue to make proposals to curb these costs. Failure by hospitals and
physicians to obtain reimbursement from third-party payors, changes in
third-party payors' policies toward reimbursement for the Beta-Cath System or
legislative action could have a material adverse effect on our business,
financial condition and results of operations.

Reimbursement systems in international markets vary significantly by country and
by region within some countries, and reimbursement approvals must be obtained on
a country-by-country basis. Many international markets have government managed
health care systems that control reimbursement for new devices and procedures.
In most markets there are private insurance systems as well as government
managed systems. Reimbursement for our products may not be available in
international markets under either government or private reimbursement systems.

Uncertainty Of Market Acceptance Of Vascular Brachytherapy And The Beta-Cath
System

Even if we obtain regulatory approvals and reimbursement from third party payors
for the use of the Beta-Cath System, our device may not gain any significant
degree of market acceptance among physicians and


                                       18
<PAGE>

patients. Vascular brachytherapy is a new treatment method and has not been used
to any significant extent by physicians outside the context of clinical trials.
We believe that physicians' acceptance of vascular brachytherapy generally and
the Beta-Cath System in particular will be essential for our operations and we
may not obtain this acceptance. Even if we establish clinical efficacy of the
Beta-Cath System, cardiologists, radiation oncologists and other physicians may
elect not to recommend vascular brachytherapy generally or the Beta-Cath System
in particular. Even if recommended, physicians may not utilize the Beta-Cath
System in a sufficient number of procedures to generate significant revenues or
to enable us to operate profitably. In addition, market acceptance of our device
could be hindered because using the Beta-Cath System currently requires the
participation not only of an interventional cardiologist, but also a radiation
oncologist appropriately credentialed to administer our beta radiation source
train.

Uncertainty Regarding Our Issued Patent, Pending Patent Applications And Other
Matters

On November 4, 1997 we received United States Patent No. 5,683,345 on the
Beta-Cath System and on May 4, 1999 we received United States Patent No.
5,899,882. United States Patent Nos. 5,683,345 and 5,899,882 may not offer any
protection to us. It may also be reexamined, invalidated or circumvented. In
addition, claims under our other pending applications may not be allowed, or if
allowed, may not offer any protection or may be reexamined, invalidated or
circumvented. Competitors may have or obtain patents that will prevent, limit or
interfere with our ability to make, use or sell our products in either the
United States or international markets.

We received a letter from NeoCardia, L.L.C., dated July 7, 1995, in which
NeoCardia notified us that it is the exclusive licensee of United States Patent
No. 5,199,939, or the Dake patent, and requested that we confirm that our
products did not infringe the claims of the Dake patent. On August 22, 1995 our
patent counsel responded on our behalf that we did not infringe the Dake patent.

The United States Patent and Trademark Office later reexamined the Dake patent.
In the reexamination proceeding some of the patent claims were amended and new
claims were added. We have concluded, based upon advice of patent counsel, that
our Beta-Cath System would not infringe any claim of the Dake patent as
reexamined.

In May 1997 Guidant acquired NeoCardia together with the rights under the Dake
patent. Guidant is attempting to develop and commercialize products that may
compete with the Beta-Cath System and has significantly greater capital
resources than the company. Guidant may sue for patent infringement in an
attempt to obtain damages from us and/or injunctive relief restraining us from
commercializing the Beta-Cath System in the United States. If Guidant were
successful in any such litigation, we might be required to obtain a license from
Guidant under the Dake patent to market the Beta-Cath System in the United
States, if such license were available, or be prohibited from selling the
Beta-Cath System in the United States. Any of these actions could have a
material adverse effect on our business, financial condition and results of
operations, or could result in cessation of our business.

We have two versions of our delivery catheter: a "rapid exchange" catheter and
an "over the wire" catheter. As a result of certain United States patents held
by other medical device manufacturers covering "rapid exchange" catheters, we
currently intend to sell the "over the wire" version of our delivery catheter in
the United States. If further investigation reveals that we may sell a "rapid
exchange" version in the United States without infringing the valid patent
rights of others, we might decide to do so in the future. However, we cannot
assure that we will be able to sell a "rapid exchange" version in the United
States without a license of third party patent rights or that such a license
would be available to us on favorable terms or at all.


                                       19
<PAGE>

The medical device industry has been characterized by extensive litigation
regarding patents and other intellectual property rights. Companies in the
medical device industry have employed intellectual property litigation to gain a
competitive advantage. There can be no assurance that we will not become subject
to patent-infringement claims or litigation or interference proceedings declared
by the United States Patent and Trademark Office to determine the priority of
inventions. The defense and prosecution of intellectual property suits, or
interference proceedings and related legal and administrative proceedings are
both costly and time-consuming. Litigation may be necessary to enforce our
patents, to protect our trade secrets or know-how or to determine the
enforceability, scope and validity of the proprietary rights of others. Any
litigation or interference proceedings will result in substantial expense to us
and significant diversion of effort by our technical and management personnel.
An adverse determination in litigation or interference proceedings to which we
may become a party could subject us to significant liabilities to third parties,
require us to seek licenses from third parties, require us to redesign our
products or processes to avoid infringement or prevent us from selling our
products in certain markets, if at all. Although patent and intellectual
property disputes regarding medical devices have often been settled through
licensing or similar arrangements, costs associated with such arrangements may
be substantial and could include significant ongoing royalties. Furthermore,
there can be no assurance that the necessary licenses would be available to us
on satisfactory terms, if at all, or that we could redesign our products or
processes to avoid infringement. Any adverse determination in a judicial or
administrative proceeding or failure to obtain necessary licenses could prevent
us from manufacturing and selling our products, which would have a material
adverse effect on our business, financial condition and results of operations.

Dependence On Single Vendor To Supply Radioisotopes

To date, we have obtained all our beta radiation isotope requirements from a
single supplier, Bebig Isotopentechnik und Umweltdiagnostik GmbH, a German
corporation. Our supply agreement with Bebig has an initial term ending in
November 2000. During the term, we have agreed not to purchase more than 30% of
our annual radioisotope requirements from any supplier other than Bebig. Our
business, results of operations and financial condition could be materially
adversely affected by Bebig's failure to provide us with beta isotopes on a
timely basis during the term of the agreement. On October 14, 1999 the Company
signed a development and manufacturing supply agreement with AEA Technologies
QSA GmbH for a second source of radioactive supply and for the development of a
smaller diameter source. The agreement provides for the construction of a
production line which is expected to be finished in February 2001. The
development of the smaller diameter source may not be successfully completed,
the new production line may not be completed on time and on budget, and the
smaller diameter source may not be manufacturable in commercial quantities.

Limited Manufacturing Experience; Scale-Up Risk

To date, we have not yet successfully commercialized the Beta-Cath System, and
our manufacturing activities have consisted of producing small quantities of our
products for use in clinical trials and our initial product launch in Europe. To
achieve profitability, the Beta-Cath System must be manufactured in commercial
quantities in compliance with regulatory requirements and at acceptable costs.
Production in commercial quantities will require us to expand our manufacturing
capabilities and to hire and train additional personnel. We have no experience
in manufacturing our products in commercial quantities. We may encounter
difficulties in scaling up production, including problems involving production
yields, quality control and assurance, component supply and shortages of
qualified personnel. Difficulties encountered in manufacturing scale up could
have a material adverse effect on our business, financial condition and results
of operations. We cannot assure that future manufacturing difficulties, which
could have a material adverse effect on our business, financial condition and
results of operations, will not occur.

Price Volatility And Fluctuations In Operating Results

The market price of our common stock could decline below the public offering
price. Specific factors relating to our business or broad market fluctuations
may materially adversely affect the market price of our common stock. The
trading price of our common stock could be subject to wide fluctuations in
response to quarter-to-quarter variations in operating results, announcements of
technological innovations, new products or clinical data announced by us or our
competitors, governmental regulatory action, developments with respect to
patents or proprietary rights, general conditions in the medical device or
cardiovascular device industries, changes in earnings estimates by securities
analysts, or other events or factors, many of which are beyond our control. In
addition, the stock market has experienced extreme price and volume
fluctuations, which have particularly affected the market prices of many medical
device companies and which have often been unrelated to the operating
performance of such companies. Our revenue or operating results in future
quarters may be below the expectations of securities analysts and investors. In
such an event, the price of our common stock would likely decline, perhaps
substantially. During the twelve month period ended September 30, 1999, the
closing price of our common stock ranged from a high of $30.25 per share to a
low of $11.00 per share and ended that period at $17.84 per share.

In addition, our results of operations may fluctuate significantly from quarter
to quarter and will depend upon numerous factors, including product development
efforts, actions relating to regulatory and reimbursement matters, progress and
costs related to clinical trials, the extent to which our products gain market
acceptance, and competition. These factors may cause the price of our stock to
fluctuate, perhaps substantially.

Item 3. Quantitative And Qualitative Disclosures About Market Risk

Interest Rate Risk

The Company's cash equivalents and short-term investments are subject to market
risk, primarily interest-rate and credit risk. The Company's investments are
managed by outside professional managers within investment guidelines set by the
Company. Such guidelines include security type, credit quality and maturity and
are intended to limit market risk by restricting the Company's investments to
high credit quality securities with relatively short-term maturities.

The table below presents principal amounts and related weighted average interest
rates by year of maturity for the Company's investment portfolio. All
investments mature, by policy, in one year or less.

Foreign Currency Risk

International revenues from the Company's foreign direct sales and distributor
sales comprised 100% of total revenues for the three and nine month periods
ending September 30, 1999. With the exception of the Australian and New Zealand
distributors, sales are denominated in Euros. The Company experienced an
immaterial amount of transaction gains and losses through the three and nine
month periods ending September 30, 1999. The Company is also exposed to foreign
exchange rate fluctuations as the financial results of its Belgian, German, and
Holland subsidiaries are translated into U.S. dollars in consolidation. As
exchange rates vary, these results, when translated, may vary from expectations
and adversely impact overall expected profitability. The net effect of foreign
exchange rate fluctuations on the Company during the three and nine month
periods ending September 30, 1999 was not material.

                  Re:   Modifications to your Employment Agreement

Dear Raoul:

      I am pleased to confirm our mutual agreement to amend your existing
employment agreement with us in recognition of your outstanding performance over
the past year.

      We will increase your annual salary to $220,000 retroactive to June 1,
1999. Based on our normal bi-weekly payroll, you will receive $8,461.54 per pay
period, less applicable withholdings and deductions.

      We will forgive repayment of your promissory note dated April 20, 1999
payable to us in the amount of $80,000 and will return your shares of common
stock that we have held as collateral for that loan.

      We will pay you a one-time lump sum cash bonus of $40,000, subject to
applicable withholdings and deductions, payable on or before September 1, 1999.

      We will pay you an additional one-time payment in the amount of $3,262,
payable on or before September 1, 1999, to cover any claims that you may have
had for a "gross-up" of your income taxes relating to the forgiveness of the
$80,000 promissory note, rent payments you received from us or otherwise.

Dear Raoul:

      You have indicated to me that you desire to return to Montreal to engage
in the practice of medicine but desire to continue to serve us on a part-time
basis. We are thrilled that you will be able to continue to make such a
commitment to us. This letter is intended to set forth our mutual agreement as
to your continued employment.

      You will become a part-time employee, commencing September 1, 1999 for a
one-year term. Your title will continue to be Vice President of Clinical Affairs
& Medical Officer, and you will report directly to the President. You will have
no direct reports. You will work on our behalf one week per month. Your
responsibilities will be defined by the President and include but not be limited
to serving as Chairman of the Quality Review Board. Further, we agree that you
may perform your responsibilities at our facilities or at any other place
considered mutually appropriate by us. Your work may require travel.

      We will pay you $70,000, plus expenses, for the services rendered by you
during the term, payable in accordance with our normal bi-weekly payroll
periods, or $2,692.31 per pay period, less applicable withholdings and
deductions. You will not be eligible to participate either in the 1999 or 2000
Company Bonus Incentive Plan, and as a part-time employee you are not eligible
for insurance or pension benefits.

      Obviously, your continued employment at Novoste, even on a part-time
basis, is subject to your receipt of proper work authorization from the
Immigration and Naturalization Service and your continuing to be in good
standing in your profession. Novoste will continue to assist you with the
renewal of your temporary visa (TN visa) as long as appropriate for employment
at Novoste. Part-time employment status will preclude your receiving permanent
work authorization in this country (green card).

1.30  "United States Authority" shall mean the United States Food and Drug
      Administration.

1.31  "Validation" shall mean the program mutually agreed to by the Parties by
      which documented evidence provides assurance that the Process will
      consistently produce Sources that meet Specifications and quality
      attributes, to the reasonable satisfaction of both Parties and the
      appropriate Regulatory Authorities.

                               ARTICLE 2 - PURPOSE

3.1   Initial Term

      The initial term of this Agreement shall commence upon the Effective Date
      and, unless terminated earlier pursuant to this Agreement, shall continue
      until the fifth anniversary of the commencement of the Commercial Phase
      ("Initial Term").

3.2   Extension

      The term of this Agreement shall be automatically extended after
      expiration of the Initial Term unless either Party has given Initial Term
      Notice to the other Party. At least two years prior to the end of the

      faith, their intentions with respect to whether or not to continue the
      term of this Agreement beyond the Initial Term.

                          ARTICLE 4 - DEVELOPMENT PHASE

4.1   Development Activities

      During the Development Phase, QSA and Novoste shall respectively carry out
      their obligations described and attributed in Schedule "A", it being
      understood that some activities may be reasonably delayed to the extent
      that such activity is premised on the work or provision of data,
      information or technology by the other Party which such other Party does
      not provide on a timely basis. Each Party shall use their best efforts in
      order to carry out their respective obligations and responsibilities set
      out in Schedule "A" to the timescales specified.

      The Parties acknowledge and agree that Schedule "A" may only be amended
      during the course of the Development Phase to accommodate unforeseen
      events and results beyond the reasonable control of the Parties. All such
      changes to Schedule "A" shall be made by written agreement of the Parties.

      The Project Managers (as specified at Article 22.1) will meet at least
      quarterly, at locations to be agreed, including videoconferencing, for the
      purpose of reviewing the status of the project and to assess progress
      against the milestones and activities set forth in Schedule "A". QSA shall
      also provide written reports to Novoste, on a monthly basis, setting out
      the progress against milestones set forth in Schedule "A".

      If Novoste has reasonable grounds to be dissatisfied with respect to any
      failure by QSA to meet its obligations described in Schedule A, Novoste,
      following written notice to QSA, may suspend payments otherwise due QSA
      and may suspend performance of its other obligations hereunder until
      reasonable satisfactory progress is achieved by QSA, or Novoste may
      terminate this Agreement by giving thirty (30) days written notice to QSA.
      Following such notice or notice under Article 4.2 hereto, QSA shall
      endeavor to bring all activities to a timely end, however QSA shall have
      the right to claim from Novoste reimbursement of all reasonable costs
      necessarily and properly incurred by them in relation to the


                                       5
<PAGE>

      orderly cessation of the work, including any commitments, liabilities or
      expenditure which are reasonably and properly incurred and would otherwise
      represent an unavoidable loss by QSA by reason of the termination of this
      Agreement. For the avoidance of doubt Novoste will not indemnify QSA
      against loss of future profit.

4.2   Development Phase Termination

      At each quarterly review meeting of the Project Managers an assessment
      shall be made of the progress of the Development Stage and the ability of
      both Parties to fulfill the terms of this Agreement. Should both Parties
      agree in writing during the Development Phase that it is no longer
      possible to fulfill the terms of this Agreement, then this Agreement shall
      be terminated.

                          ARTICLE 5 - FACILITY PROGRAM

5.1   Construction of Facility

      Subject to successful completion of the relevant parts of the Development
      Phase to the satisfaction of Novoste, QSA shall construct the Facility at
      its site in Braunschweig, Germany to carry out the manufacture of Sources.
      QSA will use its commercially reasonable best efforts to complete the
      Facility Program in accordance with the Gantt Chart set forth in Schedule
      B. Schedule B may only be modified as agreed in writing by the Parties. If
      Novoste has reasonable grounds to be dissatisfied with the performance of
      QSA in constructing the Facility in accordance with the Facility Program
      or in accordance with Schedule B, Novoste may, following written
      notification to QSA, suspend payments otherwise due QSA and Novoste may
      suspend performance of its other obligations hereunder until satisfactory
      performance is achieved or Novoste may terminate this Agreement by giving
      thirty (30) days written notice to QSA. Following such notice, QSA shall
      endeavor to bring all activities to a timely end, however QSA shall have
      the right to claim from Novoste reimbursement of all reasonable costs
      necessarily and properly incurred by them in relation to the orderly
      cessation of the work, including any commitments, liabilities or
      expenditure which are reasonably and properly incurred and would otherwise
      represent an unavoidable loss by QSA by reason of the termination of this
      Agreement. For the avoidance of doubt Novoste will not indemnify QSA
      against loss of future profit.

5.2   Facility Program Capital Cost

      The actual capital cost of the Facility Program will be calculated on a
      time and materials basis as set out in Article 9.1. The facility shall be
      completed by QSA by February 16, 2001. The budgeted capital cost for
      performance of the Facility Program by QSA is estimated at the Effective
      Date to be three million, seven hundred and sixty-four thousand euros
      ((euro)3,764,000). Any cost in excess of the estimated budgeted capital
      cost shall be subject to the prior written authorization of Novoste.

                           ARTICLE 6 - ASSET OWNERSHIP

6.1   Equipment

      (i)   Under this Agreement QSA will purchase or manufacture, on behalf of
            Novoste, the Hot Cell(s) and Equipment, which will be installed in
            the Facility as described in Schedule B. Upon completion of the
            purchase or manufacture of the Hot Cell(s) and Equipment, a warranty
            bill of sale in a form reasonably acceptable to Novoste, shall be
            executed and delivered to Novoste transferring full title to such
            Hot Cell(s) and Equipment dedicated to Novoste requirements free and
            clear of all liens, claims, or encumbrances. Subject to Novoste's
            obligations to transfer ownership of the Hot Cell to QSA under
            circumstances as set forth in this Agreement, Novoste shall at all
            times hold all right, title and interest in the Hot Cell and
            Equipment; provided, however, that during the term of this
            Agreement, usage thereof shall belong exclusively to QSA for the
            purposes of producing Sources for Novoste at the Braunschweig,
            Germany site. Since the Equipment will be in QSA's possession, QSA
            represents and warrants that the Hot Cell(s) and Equipment shall not
            be encumbered, and shall, during the term of this Agreement, remain
            free and clear of any and all encumbrances including, but not
            limited to, mortgages, charges and liens and that no effective
            financing statement, pledge or other instrument similar in effect
            covering all or any part of the Hot Cell(s) or Equipment has been
            agreed or will be agreed by QSA or Parties claiming by, through or
            under QSA.

      (ii)  In partial consideration of the services to be performed hereunder
            by QSA and in consideration of the payment of one dollar ($1.00) the
            sufficiency of which is hereby acknowledged, on the earlier of the
            natural expiration or termination of this Agreement by Novoste (for
            whatever reason other than the default by QSA), should QSA wish to
            retain the use of the Hot Cell(s), Novoste agrees without further
            notice or demand to transfer all of its right, title and interest in
            and to the Hot Cell and Equipment to QSA. After transfer of title,
            QSA will following such transfer be responsible for any
            decontamination or decommissioning costs of the Facility.

      (iii) At the conclusion of this Agreement (for what ever reason) the Hot
            Cell and other dedicated Equipment at Braunschweig, will need to be
            decontaminated . This shall be the responsibility of Novoste unless
            QSA is able and chooses to exercise its option to acquire title to
            the Hot Cells and Equipment. At the time of the completion of the
            Facility, February 16, 2001, Novoste shall establish an Escrow
            Account for the estimated cost to Decontaminate and Decommission the
            Facility (currently estimated at (euro)127,748). This Escrow Account
            shall be funded either by cash in a German bank account or by an
            irrevocable letter of credit, and be held by Novoste's attorney.
            Should QSA decline to exercise its option, or fail to be allowed to
            exercise the option due to its default of this Agreement, to own the
            Hot Cell and the Equipment, then upon the natural expiration or
            termination of this Agreement by Novoste the funds established by
            Novoste in the "Decontamination and Decommissioning" Escrow Account


                                       7
<PAGE>

            or through the letter of credit will be made available to QSA and
            shall be used exclusively for the decontamination and
            decommissioning of the Hot Cell(s) and any other Equipment prior to
            their removal by Novoste from the Braunschweig site. Should QSA
            exercise the option to own the Hot Cell(s) and the Equipment, then
            the funds held in the Escrow Account will revert to Novoste or the
            letter of credit canceled. At each calendar year end during this
            Agreement, Novoste will increase or decrease the balance of the
            Escrow Account or the letter of credit to reflect the reasonable
            costs of Decontamination and Decommissioning as estimated by QSA. If
            the balance of the Escrow Account exceeds the funds necessary for
            Decontamination and Decommissioning, the excess shall be returned to
            Novoste immediately upon completion of Decontamination and
            Decommissioning.

      (iv)  Except as may be provided in accordance with Article 16.1 sub-clause
            (vii), in no event may QSA use or permit any third Party to use the
            Hot Cell(s) or Equipment for the manufacture of any Source or Source
            Trains, any products which use technology of Novoste, or any
            products which could compete with the sale of Sources or the Medical
            Device (including the Source or Source Train) by Novoste. If title
            to the Equipment and Hot Cell(s) is obtained by QSA, QSA may not
            sell, transfer, lease, or permit the use of the Hot Cell(s) or the
            Equipment by third parties without first notifying Novoste and
            providing Novoste the opportunity to match the terms of any such
            sale, transfer, lease, or permit. Should Novoste decline to exercise
            such an option to purchase or acquire use of the Equipment and Hot
            Cell(s) then QSA shall be relieved of all obligations under this
            Article.

      (v)   It is understood that Novoste may finance the purchase and
            construction of the Hot Cell(s) and Equipment through debt and
            provide a preferred security interest (Sicherungseigentum) in the
            Hot Cell(s) and Equipment to a financing institution or other
            lender. Until such time as Novoste has made the transfer as set out
            in Article 6.1sub-clause(ii) or has otherwise transferred ownership
            of the Hot Cell(s) or Equipment as set out elsewhere in this
            Agreement (the "Transfer Date"), QSA shall have, and is hereby
            granted a secondary security interest (nachrangiges
            Anwartschaftsrecht auf Sicherungseigentum) in and to the Hot Cell(s)
            behind any security interest provided to any financing institution
            or other lender. The secondary security interest in the Hot Cell(s)
            and the provision for eventual Decontamination and Decommissioning
            set forth above shall be perfected by possession of the Hot Cell(s)
            by QSA and shall be effective as of the date of commencement of
            installation of such Hot Cell(s) and shall serve as collateral for
            the carrying out of the obligations of Novoste set out in this
            Agreement. Until the Transfer Date, QSA at all times during the Term
            of this Agreement shall be entitled to the use and possession of the
            Hot Cell(s) and Equipment in accordance with this Agreement, and the
            Hot Cell(s) and Equipment, shall be maintained and preserved by QSA
            at its expense in accordance with the provisions set out in this
            Agreement. Novoste shall execute all documents reasonably required
            to provide a secondary security interest in and to the Hot Cell(s)
            to QSA.

      (vi)  The labor rates and material handling markups on assets constructed
            by QSA or its affiliates for this Phase are set forth at Article 9.1
            hereto.

             ARTICLE 7 - GENERAL MANUFACTURE AND SUPPLY OBLIGATIONS

7.1   Source Supply

      QSA agrees to use the Process to produce Sources that meet the
      Specifications in conformity with all applicable laws, rules and
      regulations of Germany, the European Union and the United States and to
      ship Source Trains as directed by Novoste. Subject to the provisions of
      Article 27, during the Initial Term of this Agreement and any renewal or
      extension thereof, QSA shall manufacture as provided in the preceding
      sentence and provide Novoste with Source Trains which shall be ordered by
      Novoste under this Agreement for the purposes of clinical trials and
      commercial sale of the Medical Device.

7.2   Batch Size and Minimum Purchase Commitment

      Novoste agrees that it shall order Source Trains at the price set forth in
      Article 9.3 in batch sizes no smaller than the Minimum Batch Size. Novoste
      further agrees that it shall purchase from QSA a minimum of XXXXX Source
      Trains during each twelve months period after commencement of the
      Commercial Phase for the remaining period of this Agreement. Should
      Novoste not order the minimum number of Source Trains in any twelve month
      period from the commencement of the Commercial Phase, then it shall pay
      QSA a penalty of XXXXX of the price for the difference between the number
      of actual Source Trains ordered and the minimum purchase requirement for
      that period.

7.3   Testing and Documentation

      QSA shall certify in writing, to Novoste, and shall provide backup
      evidence as requested, that each Batch of Source Trains was produced and

<PAGE>

      written consent of the Parties.

7.4   Repairs and Maintenance

      After the Facility is installed, QSA shall maintain such Facility, Hot
      Cell(s) and Equipment in satisfactory operating condition as required to
      enable QSA to manufacture Sources to Specification in accordance with the
      Process and all other applicable laws, regulations, rules or orders. In
      the event of any conflict between the applicable laws, regulations, rules
      or orders, QSA will notify Novoste of such conflict and the Parties shall
      act in good faith to resolve such conflict or to determine which laws,
      regulations, rules or orders should take precedence. Routine repairs,
      preventive maintenance and service contracts for the Facility and
      Equipment shall be arranged by QSA.

                         ARTICLE 8 - GENERAL OBLIGATIONS

8.1   Isotope Supply

      QSA shall obtain Sr90 in sufficient quantities to meet its obligations
      hereunder. QSA shall at all times own the Sr90 until incorporated into
      Sources and title for the Sources passed to Novoste.

      QSA shall contract for the supply of the amount of Isotope necessary for
      QSA's production of Sources pursuant to this Agreement. Should QSA have
      difficulty in procuring Strontium 90 at competitive prices, Novoste shall
      be free to secure such supplies for QSA as are necessary for the
      production of the Sources and Source Trains pursuant to this Agreement.
      Where Novoste supplies the Strontium 90, the cost to Novoste of the
      Sources shall be adjusted accordingly.

8.2   Unavailability or Scarcity of Isotope

      It is understood that QSA's obligation to supply Isotope is conditional,
      depending upon its ability to obtain a sufficient supply of the Isotope.
      QSA will use its best efforts to locate and obtain a sufficient supply of
      Isotope to manufacture Sources required by Novoste. QSA will notify
      Novoste upon QSA's first knowledge of a shortage or likelihood of any
      shortage of Isotope if such shortage will impact the manufacture of the
      Sources. Except as set out below, QSA shall not be liable for any delays
      in the supply of Isotope if due to causes described in Article 27 hereof.

8.3   Production Planning for Clinical Trail and Commercial Supply

      During the first five (5) business days of each month commencing with the
      Commercial Phase of this Agreement, QSA and Novoste will establish a
      schedule of Batch runs for the next eight (8) weeks. Novoste shall provide
      QSA with confirmation of Batch orders no later than fourteen (14) days
      prior to a Scheduled Batch Completion Date. QSA shall be under an
      obligation to deliver to Novoste the confirmed Batch order within the
      agreed time schedule for such delivery. This approach to production
      planning may be modified as mutually agreed to by the


                                       10
<PAGE>

      Parties based upon Novoste's and QSA's experience in clinical and
      commercial supply.

                              ARTICLE 9 - PAYMENTS

9.1   Development and Facility Program

      As with the previous Agreements signed by the two Parties hereto, in
      performing the Development Phase, QSA will invoice Novoste quarterly in
      arrears, providing an adequate description of the work billed. In the
      Facility Program, QSA will provide labor at the hourly billing rates
      detailed at Schedule B, and will provide materials and equipment at QSA's
      cost plus an additional ten per cent (10%) administration fee. All charges
      not included in Schedule A or B hereto shall be subject to the prior
      written approval of Novoste. Charges shall be due only for services,
      material and equipment authorized by the terms of Schedule A or Schedule
      B. Monthly invoices that include detailed cost statements shall be
      submitted to Novoste for work performed during the prior month.

      If QSA is required to purchase items of Equipment or items necessary for
      the production of Equipment that cost more than (euro)15,000, Novoste
      shall pay such amounts one week in advance of QSA making such payments to
      third parties.

9.2   Payment for Repairs and Maintenance

      QSA shall be responsible for the payment of all repair and maintenance
      costs. Novoste will repay all reasonable expenses for any Major Repairs to
      or replacement of the Equipment except for QSA Repairs. All costing for
      all repairs shall be on the same basis as the Facility Phase.

      The maximum amount QSA will be required to pay in any calendar year for
      routine repairs, preventive maintenance and service contracts for the
      Facility and Equipment shall be fifty thousand euros ((euro)50,000), plus
      all amounts required for QSA Repairs. Any reasonable amounts for routine
      repairs, preventive maintenance and service contracts for the Facility and
      Equipment other than QSA Repairs in excess of fifty thousand euros
      ((euro)50,000) in any calendar year will be borne by Novoste. Preventive
      maintenance and service contracts for the Equipment in excess of
      twenty-five thousand euros ((euro)25,000) which are approved in advance by
      Novoste will be borne by Novoste. All amounts set forth in this Article
      shall be based on QSA's out-of-pocket costs and QSA's standard internal
      labour rates. QSA shall co-ordinate with and advise Novoste regarding the
      advisability of any Major Repair or replacement. The only repairs, if any,
      to the Facility or Equipment which shall be borne by Novoste are those set
      forth in this Article. All other repairs shall be borne by QSA.

9.3   Purchase Price for Source Trains

      Prior to the commencement of the Commercial Phase, the Parties shall agree
      the price that shall be paid by Novoste for each Source Train that QSA
      produces to Specification. Such price shall not exceed XXXXX per Source,
      exclusive of all


                                       11
<PAGE>

      packaging and taxes, but inclusive of the cost of disposal of the Sources
      at the end of the useful life of the Source Train.

9.4   Price Escalation

      XXXXX. It is therefore Novoste's expectation that there will be no price
      increase from QSA during the first two years of this Agreement after
      commencement of the Commercial Phase. QSA will be free, and is encouraged,
      to improve its gross margins by improvements in processes, scrap
      reduction, inventory management, etc. The prices for the subsequent years
      will be determined in advance by applying the average annual change in the
      German cost of living index over the preceding two years in year three and
      in the previous year for all subsequent years. Should this price increase
      calculated by using the German cost of living index exceed five percent,
      then the increase shall be calculated based upon QSA's relevant average
      annual actual rise in costs.

      It is understood that the costs of operating the Facility can be suddenly
      increased as a result of direct or indirect Regulatory changes - such as
      via the costs of conditioning and disposal of radioactive arisings. Should
      such significant changes arise at any time after the Effective Date then
      QSA shall immediately inform Novoste and the Parties shall agree a price
      increase based upon QSA's actual rise in costs.

9.5   Payment Terms

      Except as otherwise provided herein, all invoices shall be paid within 30
      days. Where there is any dispute with regard to any item on any cost

9.7   Audit

      QSA shall keep accurate books and accounts of record in connection with
      the manufacture by it of the Sources in sufficient detail to permit
      accurate determination of all figures necessary for verification of all
      compensation required to be paid pursuant to Article 9. QSA shall maintain
      such records for a period of three (3) years after the end of the year in
      which they were generated. These records may be audited by Novoste in
      accordance with this Agreement, and shall be available for review by
      Novoste at any time upon reasonable notice.

      Except as provided below, Novoste, at its sole expense and through its
      accounting personnel or, if Novoste elects, through an independent
      certified public accountant reasonably acceptable to QSA, shall have the
      right to examine the books and records of QSA relating to the activities
      of QSA hereunder and compensation due QSA hereunder for the sole purpose
      of verifying such statements. Such audit shall be conducted upon six (6)
      weeks' prior written notice to QSA during ordinary business hours, and
      shall not be more frequent than once during each calendar year except for
      those records pertaining to the supply of Strontium 90. In the case of
      Strontium 90 records, these can be inspected with 5 days notice at
      intervals no shorter than three (3) months. Novoste agrees to keep in
      strict confidence all information learned in the course of such audits,
      except when it is necessary to reveal such information in order to enforce
      its rights under this Agreement. Novoste's right to have such records
      examined shall survive termination or expiration of this Agreement for a
      period of one (1) year. As each Phase of this Agreement shall be priced
      and invoiced in a different manner, any financial audits undertaken by
      Novoste, shall be done in a way that is appropriate for the type of
      pricing and invoicing that was undertaken. In all events, QSA shall
      promptly remit to Novoste the amount of any overpayment, plus interest at
      the rate of 10% per annum from the date such payment was received by QSA
      until repaid to Novoste. In addition, if the audit reveals an overcharge
      of more than ten percent (10%) of the amount due, QSA shall reimburse
      Novoste for the cost of the related audit and any costs incident thereto,
      including attorney's fees and all costs of collection. Should such audits
      reveal that QSA have undercharged Novoste, then Novoste shall promptly
      remit to QSA such sums as have not been recovered.

                        ARTICLE 10 - ORDERS AND SHIPMENTS

10.1  Orders and Shipments

      During the term of this Agreement, Novoste will forward orders to QSA by
      facsimile (or other suitable means). Such orders shall include the
      identity of the recipient and delivery destination. Delivery of Source
      Trains to Novoste or as otherwise directed by Novoste shall be ex-Works
      transport vehicle at QSA's facility in Braunschweig, Germany. Risk for the
      goods shall pass to Novoste at point of delivery to the transport vehicle.
      Title to the goods shall pass to Novoste upon QSA receiving payment from
      Novoste.


                                       13
<PAGE>

      During the term of this Agreement QSA shall subject to Article 27.1, meet
      Novoste's orders and delivery requirements.

      Prior to the first shipment of Source Trains to any third Party site, QSA
      shall obtain from such third Party its license evidencing proper legal
      authority for the receipt and possession of the Source Trains by such
      third Party. If QSA is unable to obtain such license from the third Party,
      Novoste, upon QSA's request, shall obtain and provide such evidence of
      legal authority for the receipt and possession of the Source Trains by
      such third Party. Novoste shall obtain all approvals, licenses and permits
      required to import the Source Trains into any territory where Novoste
      directs shipments to be sent.

      QSA shall make shipping arrangement with carriers designated in writing by
      Novoste from the ex-Works point to the delivery site. All transportation
      and packaging costs incurred to deliver Source Trains ordered by Novoste
      shall be borne by Novoste.

10.2  Batch Not Meeting Specifications

      If either Party or its designee discovers that a Batch of Source Trains
      does not meet the Specifications, then the discovering Party shall
      promptly communicate in writing with the other Party to determine a
      mutually agreed course of action. With respect to any such Batch of Source
      Trains which do not meet Specifications, QSA will promptly:

      (i)   replace such Batch of Source Trains at no additional cost (with QSA
            also paying all costs to deliver such replacement Batch to the
            Novoste designated site);

      (ii)  reimburse Novoste for its actual costs incurred to return the Source
            Trains to QSA and for any purchase price paid by Novoste for such
            Source Trains; and

      (iii) indemnify Novoste for any other costs it incurs by reason of such
            Batch of Source Trains or single Source Trains not meeting
            Specifications. Such costs shall exclude any loss of profits or any
            other form of consequential loss.

10.3  Inventory Requirements

      Within one month of the commencement of the Commercial Phase of this
      Agreement, QSA shall maintain a minimum Source inventory of XXXXX Sources.
      This minimum inventory stock level shall be reviewed by QSA and Novoste at
      semi-

      (ii)  modify the technology to become non-infringing.

                ARTICLE 14 - QSA'S REPRESENTATIONS AND WARRANTIES

            respect to the Process;

      (v)   There is no action or proceeding pending or insofar as QSA knows or

      material and workmanship for a period of twelve (12) months from date of
      delivery to Novoste or delivery to a third Party as directed by Novoste.
      QSA will not be responsible for any other defects or damage under such
      warranty including but not limited to that caused by the neglect, misuse,
      abuse or alteration by Novoste or a third Party.

      QSA's obligation under such warranty shall be limited solely to an
      obligation to repair or replace all defective Source Trains and to pay or

               ARTICLE 15 - QSA'S INTELLECTUAL PROPERTY INDEMNITY

15.1  Indemnification of Novoste

      QSA hereby agrees to indemnify, defend and hold Novoste, its Affiliates
      and all of the officers, directors, employees and agents of Novoste and
      its Affiliates harmless from any and all damages arising out of or related
      to (a) the breach or falsity of any representation of QSA contained
      herein, (b) the negligent or willful misconduct of QSA or its officers,
      directors, employees or agents, or (c) any breach by QSA of its
      obligations hereunder, including without limitation its obligation to
      comply with standard operating procedures.

      QSA agrees to defend, indemnify and hold Novoste, its officers, directors
      and employees harmless from and against any liabilities, claims, damages
      and expenses (including reasonable attorneys' fees) which Novoste and such
      indemnified Parties may be compelled to pay in any judgment, claim or
      action arising from infringement of third Party copyright, patents,
      technology or other intellectual property rights resulting from QSA's use
      under this Agreement of Background Technology. Novoste shall give written
      notice of any legal action promptly after Novoste's first knowledge
      thereof. QSA shall have sole and exclusive control of the defense of any
      legal action, including the choice and direction of any legal counsel.
      Novoste may not settle nor compromise any such legal action without the
      written consent of QSA. This indemnity shall survive termination of this
      Agreement.

      In the event that any portion of the Background Technology developed is,

      or intellectual property rights infringement, either Party reserves the
      right and may at its option:

      (i)   procure the right to continue using the technology; or

      (ii)  modify the technology to become non-infringing.

                  ARTICLE 16 - LICENSES, PATENTS AND TECHNOLOGY

16.1  Ownership of Work Performed

      (i)   Since all development work has been funded by Novoste, and QSA has
            brought significant Background Technology, QSA and Novoste agree and
            acknowledge, that any and all arising ideas, improvements,
            inventions and works of authorship conceived, written, created or
            first reduced to practice in the performance of this Agreement,
            shall be jointly owned and be the equal property of both Novoste and
            QSA. QSA on behalf of its stockholders, directors, employees,
            officers, Affiliates and representatives hereby assigns to Novoste
            an equal right, title and interest in and to any and all such
            arising ideas, improvements, inventions and works of authorship.
            Jointly Owned Arising IP includes technology related to the XXXXX
            containing 90SrF2 created for the manufacture of Sources.

      (ii)  Notwithstanding the foregoing sub-clause (i), but subject to
            sub-clause (iii) hereof, Jointly Owned Arising IP shall not include
            any of the Background Technology or Novoste Technology. Further it
            shall not include any modifications or improvements to Background
            Technology that are conceived, written, created or first reduced to
            practice by QSA during the term of this Agreement but unrelated to
            the performance of this Agreement by QSA.

      (iii) All data, information, or technology supplied to QSA by Novoste to
            assist QSA in carrying out its obligations hereunder, shall remain
            the property of Novoste and shall be returned by QSA to Novoste upon
            expiration or termination of this Agreement.

      (iv)  QSA agrees that it will manufacture Source Trains exclusively for
            Novoste. This Article will remain in effect and survive the
            termination of this Agreement for an additional three years, unless
            otherwise agreed in writing by Novoste,

      (v)   Subject to sub-clause (viii) hereto, QSA and Novoste agree that the
            Jointly Owned Arising IP shall not be sold, licensed, assigned or
            otherwise provided to any third party without the prior written
            agreement of the other Party, provided that Novoste shall not
            unreasonably withhold agreement for QSA to license a third party if
            required for the purpose of exploiting any non-medical application
            of the Jointly Owned Arising IP. Further, in the event that there
            are medical applications for the Jointly Owned Arising IP which are
            outside the scope of this Agreement the Parties shall consult and
            seek to reach agreement by which such medical

             applications can be jointly exploited, if possible by extending the
             scope of this Agreement thereto.

      (vi)   Following agreement by the two Parties as to the countries in which
             any patents will be filed, QSA and Novoste agree to jointly and
             equally fund the filing, prosecution and maintenance of patent
             applications and any other registration actions and any litigation
             relating to Jointly Owned Arising IP. In the event of legal
             proceedings relating to Jointly Owned Arising IP become necessary
             to defend the Jointly Owned Arising IP, both Parties shall be in
             agreement to take part in such proceedings, and neither Party shall
             unreasonably refuse to participate in such proceedings.

      (vii)  QSA and Novoste agree that all potential incremental improvements
             to the Jointly Owned Arising IP will be discussed in advance.
             Should either Party not be interested in pursing additional medical
             or industrial applications, and thus not fund such new development
             areas, then the technology related to these new application areas
             will be owned exclusively by the Party funding such development.
             Under these circumstances the licensing of any Intellectual
             Property owned by the other Party necessary for the use of such
             developments shall be agreed at a reasonable market rate. Should
             QSA require the use of the Equipment or Hot Cells to undertake such
             development outside the medical area, then they agree to advance a
             payment to Novoste of a reasonable fee for the use of the facility.
             It is understood that Novoste's seed train production will always
             have priority.

      (viii) In the event this Agreement expires or is terminated by Novoste
             under Article 21.1 or by QSA for any reason except under Article
             21.1, QSA grants to Novoste a non-exclusive, non-transferable,
             royalty free license to use and develop Background Technology
             related to the manufacture of Source Trains. In the event Novoste
             terminates this Agreement for any other reason, QSA agrees to grant
             Novoste a license to the Background Technology at reasonable,
             commercial terms to be agreed by the two Parties. Neither Party
             shall transfer in any way rights to the Jointly Owned Arising IP to
             a third party without first notifying the other Party and providing
             them with the opportunity to match the terms of any such transfer.
             Should the other Party decline to exercise such an option to
             purchase or acquire use of the notifying Party's Jointly Owned
             Arising IP then the notifying Party shall be relieved of all
             obligations under this sub-clause.

16.2  Patent Applications

      QSA shall prepare all papers, including patent applications, invention
      assignments and copyright assignments, to perfect the rights, title and
      other interests in the Jointly Owned Arising IP, and QSA, wherever
      permitted under the law, shall file and execute such papers jointly in its
      own name and in the name of Novoste. Reasonable costs related to such
      preparation and filing shall be shared equally.

      This Article 16 shall survive the termination of this Agreement for any
      reason including expiration of the term.

                         ARTICLE 17 - REGULATORY MATTERS

17.1  Novoste Responsibilities

      It shall be the responsibility of Novoste or its designee to file, obtain
      and maintain such licenses, registrations, listings, authorizations and
      approvals as the European Authority or United States Authority or any
      other applicable governmental entity may require to enable use of the
      Source Train in association with the Medical Device. QSA shall provide to
      Novoste as requested or, at QSA's discretion directly to the regulatory
      authority (in order to protect the proprietary nature of the information),
      all required information in its possession necessary to assist Novoste in
      filing, obtaining and maintaining all licenses, registrations, listings,
      authorizations and approvals of any governmental entities necessary for
      the use of Source Trains in conjunction with the Medical Device and in
      order to seek marketing authorization for the Medical Device.

17.2  QSA Responsibilities

      QSA shall be responsible for obtaining and maintaining all necessary
      facility licenses, registrations, authorizations and approvals, other than
      those required to market the Medical Device or use it in clinical trials,
      which are necessary to develop, manufacture, handle, store, label,
      package, dispose of, transport and ship Source Trains and radioactive
      materials in the U.S., Germany, and other jurisdictions specified by
      Novoste.

17.3  Governmental Inspections, Compliance Review and Inquiries

      Upon request of any governmental entity or any third Party entity
      authorized by a governmental entity, such entity shall, for the purpose of
      regulatory review, have access to observe and inspect the Facility and
      procedures used for the manufacturing, testing, storage and shipping of
      Sources, including Process development operations, and to audit such
      Facilities for compliance with applicable regulatory standards, and to
      perform such other activity as such entity may be authorized to undertake.
      QSA shall give Novoste prompt notice of any upcoming inspections or audits
      by a government entity of the Facility or procedures and shall provide
      Novoste with a written summary of such inspection or audit following
      completion thereof. QSA agrees to use commercially reasonable efforts to
      promptly rectify or resolve any deficiencies noted by a government entity
      whether communicated orally, in a report or correspondence or otherwise
      issued to QSA.

17.4  Access to the Facility

      Novoste shall have reasonable access to the Facility and procedures:


                                       21
<PAGE>

      (i)   at least once per calendar quarter and more frequently for good
            cause, for the purpose of observing the Process development relating
            to the Sources, and

      (ii)  no more frequently than semiannually (except for good cause) for the
            purpose of auditing the Facility for compliance to applicable
            regulatory requirements and standards relating to the Sources and
            timely performance by QSA of its obligations hereunder.

      After commencement of the Commercial Phase, Novoste shall, as mutually
      agreed and no less frequently than semiannually (except for good cause),
      be entitled to access to the Facility for the purpose of observing any
      Process development or to audit the Facility for compliance with
      specifications and other regulatory requirements. QSA shall provide access
      to Novoste, on a continuing basis, to all QSA protocols, standard
      operating procedures and manufacturing records, as is necessary or
      relevant for the development, manufacture, handling, storage, labeling,
      packaging, disposing, transportation and shipment of Source Trains, which
      may be required in obtaining or maintaining licenses, registrations,
      authorizations and regulatory authorization of the Medical Device. All
      such information disclosed to Novoste or its employees or agents, shall be
      deemed to be Novoste's Confidential Information as such term is defined in
      this Agreement.

17.5  Approval for Manufacturing Changes

      QSA agrees that no changes will be made to any materials, Specifications,
      Equipment, Hot Cell(s) or methods of production or testing the Sources,
      without Novoste's prior written approval. Subsequent to such approval by
      Novoste, QSA may then make such approved changes in manufacturing
      procedures, so long as in any event:

      (i)   such changes are permitted by applicable government regulations and
            the terms of any licenses, registrations, authorizations or
            approvals previously granted by the applicable governmental entity
            with respect to the Medical Device, and

      (ii)  Novoste receives copies of all documentation relating to such
            approved changes.

      If the changes require the additional license, registration, authorization
      or approval of any applicable governmental entity in Europe, United States
      or elsewhere, such changes may not be implemented until QSA receives
      written notice that the governmental entity or entities has or have
      authorized or approved the change. Each Party shall cooperate fully with
      the other in preparing data and information for a submission requesting
      prior authorization or approval of a change in materials, specifications,
      equipment or methods of production or testing. However, where changes are
      required to be made at the request of a regulatory body, Novoste shall not
      withhold their agreement to such changes.

17.6  New Regulatory Requirements

      Each Party shall promptly notify the other of new regulatory requirements
      of which it becomes aware which are relevant to the manufacture of Sources
      under this Agreement and which are required by the European Authority,
      United States Authority or other applicable governmental entities and the
      Parties shall confer with each other with respect to the best means to
      comply with such requirements. QSA shall be responsible for implementing
      and complying with any new or revised regulatory requirements arising

      other from and against any and all costs, claims, judgements or other
      expenses, including reasonable attorney fees, arising as a result of
      damages claimed by third parties, in tort, contract or other legal theory,

      writing of any action, claim or other matter in respect of which the
      Indemnitee, or any of their respective directors, officers, employees or
      agents intend to claim such indemnification; provided, however, the
      failure to provide such notice within a reasonable period of time shall
      not relieve the Indemnitor of any of its obligations hereunder except to
      the extent the Indemnitor is prejudiced by such failure. The Indemnitor
      shall have sole and exclusive control of the defense of any legal action,
      including the choice and direction of any legal counsel. The Indemnittee
      may not settle nor compromise any legal action without the written consent

                      ARTICLE 19 - DISCLOSURE OF TECHNOLOGY

19.1  Disclosure

      Except as otherwise set out, it is agreed that disclosure of data,
      information or technology by QSA or Novoste, to the other, during the term
      of this Agreement shall not, except to the extent granted herein,
      constitute any grant, option or license under any patent, technology or
      other rights, held by QSA or Novoste.

                          ARTICLE 20 - CONFIDENTIALITY

20.1  Confidentiality and Exceptions

      During the term of this Agreement and for a period of ten (10) years

      including Background Technology, Novoste Technology, Jointly Owned Arising
      IP and know-how, data, processes, methods, techniques, formulas, test data
      and other information disclosed to such Party by the other Party whether
      or not it is identified as "Confidential Information" by the disclosing
      Party (collectively "Confidential Information"). This obligation of
      confidentiality shall not apply to the extent that it can be established
      by the Party in receipt of such Confidential Information, that the
      information:

      i)    was already known to the receiving Party at the time of disclosure;

      ii)   was generally available to the public or otherwise part of the
            public domain at the time of its disclosure;

      iii)  became generally available to the public or otherwise part of the
            public domain after its disclosure to the receiving Party through no
            act or omission of the receiving Party;

      iv)   was disclosed to the receiving Party by a third Party who had no
            obligation to restrict disclosure of such information; or

      v)    was independently developed by the receiving Party without any use
            of Confidential Information of the disclosing Party.

      Notwithstanding the foregoing, QSA and Novoste may both disclose
      Confidential Information to an Affiliate provided that the Affiliate is
      bound by confidentiality to the same extent as QSA and Novoste hereunder.
      The Party disclosing Confidential Information to such Affiliate shall be
      liable for any unauthorized use or disclosure of the Confidential
      Information by the Affiliate.

      This Article shall survive termination or expiration of this Agreement in
      accordance with its terms.

      Such insurance policy shall designate Novoste as loss payee in the event
      of any loss or damage involving any asset owned by Novoste and shall name
      Novoste as an additional insured. QSA agrees that such insurance shall be

      upon request, provide to Novoste a certificate of insurance designating
      Novoste as loss payee in event of any loss or damage covered by sub-clause
      (ii) of this Article, provided that any proceeds so received as a result
      of less than a total loss shall be used to repair such damaged or
      destroyed assets, including, but not limited to, the Hot Cell(s) and the
      Equipment. Any insurance proceeds held by QSA pursuant to this Article
      shall be used to repair or replace such damaged Facility and QSA shall

      coverage. This Article shall survive termination of this Agreement with
      respect to sub-clause (ii) of the first sentence of this Article.

      In addition, during the Term of this Agreement and for a period of four
      years after the expiration or other termination hereof, QSA shall maintain

      insurance shall (a) include coverage insuring against Damages resulting
      from or caused by (or claimed to be resulting from or caused by) the
      operation or use of any Source shipped or repaired by QSA (b) shall have
      coverage limits of not less than U.S. $8,000,000 per occurrence and U.S.
      $8,000,000 in the aggregate, and shall name Novoste as an additional
      insured. Within 15 days after the execution of this Agreement, QSA will
      deliver to Novoste copies of all policies effecting such insurance (in
      English) with a certificate (in English) of QSA's insurance broker stating
      that all premiums then due have been paid.

                                   Schedule C

                               PRODUCT DESCRIPTION

The BETA-CATH(TM) System was developed to reduce the incidence of coronary
artery restenosis following angioplasty through the delivery of a prescribed
dosage of beta radiation to the balloon injury site. It is an integrated system
comprised of three separate components: the Delivery Catheter, the Transfer
Device, and the Radiation Source Train. However, the System will most likely be
sold or leased as only two discrete units of sale: 1) the Delivery Catheter and
2) the Transfer Device containing the Radiation Source Train.

Delivery Catheter

The Delivery Catheter is an invasive device which provides access to the site of
balloon injury and the path through which the Radiation Source Train is
delivered to the angioplasty treatment site in the coronary artery. The current
catheter design is a triple lumen, 5Fr, single extrusion. The three lumens (the
Source Train lumen, the hydraulic return lumen and the guidewire lumen) allow
for the transfer of the guide-wire and Radiation Source Train, as well as
providing a closed hydraulic return loop. The catheter design consists of a
rapid-exchange design for the guide-wire lumen primarily for the European
market, known as the Beta-Rail(TM), and an over-the-wire design for the US
market, known as the Beta-Cath(TM).

Transfer Device

The ergonomically-designed Transfer Device houses the Radiation Source Train and
controls the hydraulics during the radiation treatment procedure. The handheld
Transfer Device holds the Radiation Source Train until the user depresses a
syringe attached to the Transfer Device; this action hydraulically delivers the
Radiation Source Train to the treatment zone within the Delivery Catheter. At
the end of the treatment, the switching mechanism in the Transfer Device allows
the hydraulic pressure to propel the Radiation Source Train back into the
Transfer Device. The Transfer Device has also been designed to protect
healthcare workers and patients from significant unintended radiation exposure.

Source Train

The Source Train consists of a series of independent cylindrical sources, with
an inactive gold marker at each end, providing the radiation dosage for the
treatment procedure. Each source is composed of radioactive materials (Sr90/Y90)
XXXXX. XXXXX. The Source Train will be contained within the Transfer Device when
it is sold commercially and will be offered in 30mm, 40 mm, 50 mm and 60mm
lengths.
