                                PLC SYSTEMS INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 March 31, 2000


1.       BASIS OF PRESENTATION

         The accompanying unaudited condensed consolidated financial statements
have been prepared in accordance with generally accepted accounting principles
for interim financial information and with the instructions to Form 10-Q and
Article 10 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes 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. Operating results for the three-month period
ended March 31, 2000 are not necessarily indicative of the results that may be
expected for the year ended December 31, 2000. Certain prior period items have
been reclassified to conform with current period presentations. These financial
statements should be read in conjunction with the consolidated financial
statements and footnotes thereto included in the Company's annual report on Form
10-K for the year ended December 31, 1999.

2.       NET LOSS PER SHARE

         Basic earnings per share is computed based only on the weighted average
number of common shares outstanding during the period and exclude any dilutive
effect of options, warrants and convertible securities. Diluted earnings per
share is computed using the weighted average number of common shares outstanding
during the period, plus the dilutive effect of future issues of common stock
relating to options, warrants and convertible securities. In calculating diluted
earnings per share, the dilutive effect of options, warrants and convertible
securities is computed using the average market price for the period unless
their inclusion would be antidilutive.

3.       COMPREHENSIVE LOSS

         The Company has adopted Statement 130, Reporting Comprehensive Income
("Statement 130"). Statement 130 establishes new rules for the reporting and
display of comprehensive income and its components; however, the adoption of
Statement 130 had no impact on the Company's net loss or shareholders' equity.
Statement 130 requires unrealized gains or losses on the Company's
available-for-sale securities and foreign currency translation adjustments,
which prior to adoption were reported separately in shareholders' equity, to be
included in other comprehensive income.

         Total comprehensive loss for the three-month period ended March 31,
2000 amounted to $2,207,000, as compared to $2,206,000 for the three-month
period ended March 31, 1999.

5.       LEGAL PROCEEDINGS

         In September 1996, CardioGenesis filed a civil lawsuit in the United
States District Court for the Northern District of California asking the court
to declare the Company's synchronization patent (U.S. Patent No. 5,125,926)
invalid and unenforceable, or, alternatively, to find that CardioGenesis' TMR
and PMR lasers do not infringe this patent. The Company filed a counterclaim
alleging that all of CardioGenesis' TMR and PMR lasers infringe U.S. Patent No.
5,125,926. In January 1997, CardioGenesis filed an opposition in the European
Patent Office to have the Company's German synchronization patent declared
invalid. In April 1997, the Company filed an infringement lawsuit against
CardioGenesis and one of its distributors in the Munich District Court alleging
that CardioGenesis' TMR and PMR lasers infringe the Company's German
synchronization patent. The PLC patents at issue in these lawsuits cover the
Company's synchronization technology, which the Company believes is a critical
factor in increasing the safety of TMR and PMR procedures.

         In January 1999, the Company settled its outstanding patent
infringement litigation with CardioGenesis, who subsequently merged with Eclipse
Surgical Technologies, Inc. Under the settlement, CardioGenesis agreed that U.S.
Patent No. 5,125,926 and related international patents of the Company are valid
and enforceable. PLC granted CardioGenesis a non-exclusive worldwide license to
the patents in exchange for payment of a license fee and ongoing royalties over
the life of the patents (at least 10 years unless the patents are all held
invalid in future lawsuits). As part of the settlement, CardioGenesis agreed to
pay the Company:

     -    a minimum of $2.5 million over the next 42 months; and

     -    license fees and ongoing royalties on sales of all covered products
          for at least 10 years (unless the patents are all held invalid in
          future lawsuits).

         In July 1997, a U.S. Food and Drug Administration ("FDA")
advisory panel recommended against approval of the Company's application to
market The Heart Laser System in the United States. Following this
recommendation, the Company was named as defendant in 21 purported class action
lawsuits filed between August 1997 and November 1997 in the United States
District Court for the District of Massachusetts. The lawsuits seek an
unspecified amount

                                   (Continued)


of damages in connection with alleged violations of the federal securities laws
based on the Company's failure to obtain a favorable FDA panel recommendation in
1997. Nineteen of these complaints have been consolidated by the court into a
single action for pretrial purposes (hereafter referred to as the "federal
suit"). Two of these suits were voluntarily dismissed. The Company moved to
dismiss all claims in the federal suit. On March 26, 1999, the court issued an
order dismissing some, but not all, of the claims in the federal suit. The
parties filed cross motions for reconsideration and on October 12, 1999, the
court dismissed additional, but not all remaining claims in the federal suit.
The Company cannot make a meaningful estimate of the amount or range of loss
that could result from an unfavorable outcome of this lawsuit, but an
unfavorable outcome could have a material adverse effect on the Company's
business, financial position and results of operations. The Company believes
that it has meritorious defenses to this litigation matter and continues to
vigorously defend itself.

         The Company also was named as a defendant in a lawsuit filed in
Massachusetts Superior Court in September 1998 (hereafter referred to as the
"state suit") seeking over $2 million in damages for alleged negligent
misrepresentations and fraud arising from the Company's failure to obtain a
favorable FDA recommendation in 1997. The state suit settled on confidential
terms, and a Stipulation of Dismissal was filed on April 13, 2000. The
settlement of the lawsuit did not have a material impact on the Company's
financial statements.

         In February 1996, PLC Medical Systems, Inc. filed suit against Eclipse
Surgical Technologies, Inc. ("Eclipse") in the United States District Court for
the District of Massachusetts alleging copyright infringement and unfair and
deceptive trade practices based on Eclipse's misappropriation and copying of one
of PLC's confidential clinical study protocols. The Company settled this suit in
April 1999 on confidential terms. The settlement of the lawsuit did not have a
material impact on the Company's financial statements.

         In October 1997, the French Ministry of Health suspended commercial
use of TMR devices in France. In November 1998, a hospital in France, Centre
Medico Chirurgical Foch ("Foch Hospital"), sued the Company's Portuguese
subsidiary, PLC Sistemas Medicos Internacionais Lda., and a third party,
Johnson & Johnson Leasing GmbH, in Paris, France alleging breach of contract
and seeking reimbursement of lease payments made for The Heart Laser System.
On April 18, 2000, the Tribunal de Grande Instance de Paris dismissed this
suit for lack of jurisdiction. The Company can make no assurance as to
whether Foch Hospital will appeal this decision or bring suit in another
jurisdiction.

6.       EQUITY FINANCING

         On March 28, 2000, the Company issued and sold 2,683,000 shares of
common stock to two institutional investors at a price of $2.00 per share,
resulting in proceeds to the Company (net of all issuance costs) of
approximately $5,075,000. In connection with this financing the Company issued a
placement agent a three-year warrant exercisable for 61,326 shares of common
stock at a price of $3.15 per share. The Company may seek additional financing
through the issuance and sale of debt or equity securities, bank financing,
joint ventures or by other means. The availability of such financing and the
reasonableness of any related terms in comparison to market conditions cannot be
assured.

7.       LEASE RECEIVABLES

         The Company utilizes third-party financing arrangements to provide an
array of lease financing alternatives to hospitals interested in acquiring The
Heart Laser System. The lease financing alternatives available compliment the
Company's traditional placement and sales strategies.

         Under these arrangements, the Company receives payment from the leasing
company equal to the present value of guaranteed minimum payments due from the
customer after customer acceptance of The Heart Laser System. In transactions
where the Company has transferred substantially all of the risks and rewards of
ownership to the customer and the customer has accepted The Heart Laser System,
the Company recognizes revenue, which is reported as a component of product
sales. The Company recognizes a lease receivable equal to the present value of
the guaranteed minimum payments until such time as the Company can legally
isolate the lease receivables. The payment received from the leasing company is
recognized as a secured borrowing. Interest income and interest expense related
to the lease receivables and secured borrowing, respectively, is recognized over
time using the effective interest method. Equal amounts of interest income and
interest expense are included as a component of other income, net, in the
Consolidated Statement of Operations.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS


         This quarterly report contains forward-looking statements regarding
anticipated increases in revenues, marketing of products and proposed products
and other matters. These statements, in addition to statements made in
conjunction with the words "anticipate," "expect," "intend," "believe," "seek,"
"estimate" and similar expressions, are forward-looking statements that involve
a number of risks and uncertainties. Such statements are based on management's
current expectations and are subject to a number of risks and uncertainties that
could cause actual results to differ materially from these forward-looking
statements. Such factors and uncertainties include, but are not limited to,
business conditions and growth in certain market segments and the general
economy, the ability of the Company to secure any required additional financing,
an increase in competition or other competitive developments, the lack of market
acceptance of the Company's products and proposed products by healthcare
professionals and third party payers, the lack of reimbursement by third party
payers, the development of alternative treatments or procedures for the
treatment of heart disease and other risks and uncertainties indicated from time
to time in the Company's filings with the Securities and Exchange Commission,
including without limitation in "Item 7 - Management's Discussion and Analysis
of Financial Condition and Results of Operations - Risk Factors" of the
Company's Annual Report on Form 10-K for the fiscal year ended December 31,
1999, which are expressly incorporated by reference herein. The Company
undertakes no obligation to revise any forward-looking statements to reflect
events or circumstances that may arise after the date of this report.

OVERVIEW

         The Company offers placement, purchase and leasing alternatives to
customers interested in acquiring The Heart Laser System. The Company has
developed a strategy to address the challenges of marketing high cost capital
equipment by offering The Heart Laser System on a usage basis to hospitals. The
particular structure of a usage based contract, including the length of
contract, price billed per procedure and end of term options for purchase,
depends primarily on whether the hospital is willing and able to commit to a
certain minimum volume of procedures over a defined period of time. If the
hospital cannot commit to a sufficient number of procedures, The Heart Laser
System may be installed with usage fees billed as agreed upon with the hospital.
The Company refers to this type of usage arrangement as a retained placement
contract. Under a retained placement contract, placement and service fee revenue
is recorded over the term of the usage agreement and The Heart Laser System
remains the property of the Company and is depreciated over the term of the
usage agreement.

         If the hospital is willing and able to commit to a sufficient number of
procedures such that the substantial risks and benefits of ownership of The
Heart Laser System have transferred to the hospital, then the Company classifies
the usage agreement as a minimum procedure sales contract. Under a minimum
procedure sales contract, the Company records product revenue, at a discounted
present value of the guaranteed minimum procedure payments, and records product
cost of sale at the time of acceptance of The Heart Laser System.

         The Company believes that retained placement and minimum procedure
sales contracts are appealing to hospitals when capital equipment funds are
scarce or unavailable or when it is


                                     - 10 -





difficult to predict early usage as is the case with new technology such as TMR.
The Company's lease financing arrangements enables the Company to monetize
future payment streams associated with certain agreements. If utilization
becomes more predictable, the Company expects a significant number of new
accounts to opt for conventional leasing, or direct purchase.

         The Heart Laser System is also sold to customers, and the related
sterile handpieces and other disposables are sold separately for each procedure.
These sales are classified as product sales.

         Customers are given the option to purchase service contracts to cover
the cost of maintaining The Heart Laser System beyond the applicable warranty
period. These service revenues are recorded ratably over the service contract
and are classified as a component of placement and service fees.

RESULTS OF OPERATIONS

         Total revenues for the three-month period ended March 31, 2000 were
$1,742,000, a decrease of $1,104,000 when compared with total revenues of
$2,846,000 for the three-month period ended March 31, 1999. Product sales for
the three-month period ended March 31, 2000 were $894,000, a decrease of
$1,265,000 when compared with product sales of $2,159,000 for the three-month
period ended March 31, 1999. The major factors in these decreases are the
decline in the number of Heart Laser System sales transactions recognized
during the three month period ended March 31, 2000, as well as a lower
average selling price for The Heart Laser System in 2000 as compared to 1999.
In the three months ended March 31, 2000, the Company recorded only one Heart
Laser System sales transaction, while in the 1999 comparable period the
Company recorded four Heart Laser System sales transactions. Included in
product sales for the three months ended March 31, 2000 and 1999 are royalty
and license payments associated with the CardioGenesis patent dispute.

         Placement and service fees for the three-month period ended March 31,
2000 were $848,000, an increase of $161,000, when compared with placement and
service fees of $687,000 for the same period in fiscal 1999. This increase is
due to both increased utilization of installed Heart Laser Systems and a
redeployment strategy that moves under-performing Heart Laser Systems to more
productive sites.

         Total gross margin for the three-month period ended March 31, 2000
approximated 43% of revenues, down from 52% for the comparable period in fiscal
1999. In the 2000 period, the Company did not generate sufficient sales volume
to efficiently cover manufacturing costs, resulting in lower gross margins.

         Selling, general and administrative expenditures were $2,580,000 for
the three-month period ended March 31, 2000, a decrease of $62,000 when
compared to expenditures of $2,642,000 in the comparable period in fiscal
1999. As a result of the Company's restructuring of its workforce in April
1999, the Company reduced compensation expense in the three-month period
ended March 31, 2000 as compared to the three-month period ended March 31,
1999. The Company used the savings from the headcount reduction to increase
its sales and marketing expenditures in the three-month period ended March
31, 2000, as compared to the three-month period ended March 31, 1999,
particularly in the areas of internet/web expansion, tradeshows, advertising
and marketing literature.

                                     - 11 -





         Research and development expenditures for the three-month period ended
March 31, 2000 were $456,000, a decrease of $592,000 when compared with
expenditures of $1,048,000 for the three-month period ended March 31, 1999. The
reduction in research and development expenses primarily reflects reduced
compensation expense resulting from the Company's reduction in its workforce in
April 1999.

         Other income for the three-month period ended March 31, 2000 was
$97,000, an increase of $90,000 when compared with other income of $7,000 for
the three-month period ended March 31, 1999. The three-month period ended March
31, 2000 included income from an insurance settlement while the comparable 1999
period included foreign currency translation losses.

         The Company incurred a net loss of $2,183,000 for the three-month
period ended March 31, 2000, compared to a net loss of $2,199,000, for the
comparable 1999 period.

LIQUIDITY AND CAPITAL RESOURCES

         At March 31, 2000, the Company had cash and cash equivalents of
$8,085,000.

         Over the past three years, the Company incurred significant operating
losses and utilized significant amounts of cash to fund operations. The Company
is in a critical stage in its growth as it continues to transition from a
research and development company to a commercial company with complete sales,
marketing and production capabilities.

         On March 28, 2000, the Company issued and sold 2,683,000 shares of
Common Stock to two institutional investors at a price of $2.00 per share,
resulting in proceeds to the Company (net of all issuance costs) of
approximately $5,075,000. In connection with this financing, the Company issued
a placement agent a three-year warrant for 61,326 shares of common stock at a
price of $3.15 per share. The Company may seek additional financing through the
issuance and sale of debt or equity securities, bank financing, joint ventures
or by other means. The availability of such financing and the reasonableness of
any related terms in comparison to market conditions cannot be assured.

         While the Company is encouraged by recent developments with respect
to FDA approval and Medicare coverage for TMR procedures, the historical
absence of widespread reimbursement for the TMR procedure by third party
payers has limited demand for and use of The Heart Laser System. Although
Medicare reimbursement began in July 1999, and some private insurance plans
have begun reimbursing health care providers for TMR procedures using The
Heart Laser System, the Company believes that operating losses are likely to
continue until such time as third party payers begin to provide widespread
reimbursement to healthcare providers for use of The Heart Laser System.
Management believes that its existing cash resources and cash from operations
will meet working capital requirements through 2000. However, unanticipated
decreases in operating revenues or increases in expenses, inability to
monetize usage agreements or further delays in the process of third party
payers providing reimbursement to healthcare providers may adversely impact
the Company's cash position and require further cost reductions or the need
to obtain additional financing. No assurance can be given that the Company
will be successful in achieving broad commercial acceptance of The Heart
Laser System or that the Company will be able to operate profitably on a
consistent basis. Should additional financing not be available on terms and
conditions acceptable to the Company,

                                     - 12 -





additional actions may be required that could adversely impact the Company's
ability to continue to realize assets and satisfy liabilities in the normal
course of business. The consolidated financial statements set forth in this
quarterly report do not include any adjustments to reflect the possible future
effects of these uncertainties.

         During the three-months ended March 31, 2000, the Company incurred a
net loss of $2,183,000, which resulted in the use of approximately $636,000 of
its cash resources to support operations. Cash used by investing activities was
approximately $780,000 and primarily related to PLC's retained placement
contract activity. Cash provided by financing activities was approximately
$5,029,000 and primarily related to the net proceeds of $5,075,000 obtained from
the sale of the Company's common stock on March 28, 2000, offset by a decrease
in secured borrowings of $46,000.

         The Company and certain of its officers have been named as defendants
in 21 purported class action lawsuits filed between August 1997 and November
1997. See Note 5 in the accompanying condensed consolidated financial statements
for further discussion.

         YEAR 2000

         In prior years, the Company discussed the nature and progress of its
plans to become Year 2000 ready. In late 1999, the Company completed its
remediation and testing of systems. As a result of those planning and
implementation efforts, the Company experienced no significant disruptions in
mission critical information technology and non-information technology systems
and believes those systems successfully responded to the Year 2000 date change.
The Company did not incur material expenses in the first quarter of 2000 in
connection with remediating its systems to become Year 2000 ready. The Company
is not aware of any material problems resulting from Year 2000 issues, either
with its products, its internal systems, or the products and services of third
parties. The Company will continue to monitor its mission critical computer
applications and those of its suppliers and vendors through the year 2000 to
ensure that any latent Year 2000 matters that may arise are addressed
completely.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

         A portion of the Company's operations consists of sales activities in
foreign jurisdictions. The Company manufactures its products exclusively in the
United States and sells the products in the United States and abroad. As a
result, the Company's financial results could be significantly affected by
factors such as changes in foreign currency exchange rates or weak economic
conditions in the foreign markets in which the Company distributes its products.
The Company's operating results are exposed to changes in exchange rates between
the U.S. dollar and foreign currencies, especially the Swiss Franc and the
German Mark. When the U.S. dollar strengthens against the Franc or Mark, the
value of nonfunctional currency sales decreases. When the U.S. dollar weakens,
the functional currency amount of sales increases. Overall, the Company's
support of its foreign operations results in a benefit of a stronger U.S.
dollar, but is adversely affected by a weaker U.S. dollar relative to major
currencies worldwide. The Company does not believe that its exposure is
significant.

         The Company's interest income and expense are most sensitive to changes
in the general level of U.S. interest rates. In this regard, changes in U.S.
interest rates affect the interest earned on the Company's cash equivalents as
well as interest paid on its debt.
