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 and six month
periods ended June 30, 1999 are not necessarily indicative of the results that
may be expected for the year ended December 31, 1999. For further information,
refer to the consolidated financial statements and footnotes thereto included in
the Company's annual report on Form 10-K for the year ended December 31, 1998.

2.       NET LOSS PER SHARE

         In 1998, the Financial Accounting Standards Board issued Statement No.
128, Earnings Per Share ("Statement 128") which replaced the calculation of
primary and fully diluted earnings per share with basic and diluted earnings per
share. Unlike primary earnings per share, basic earnings per share exclude any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share are very similar to the previously reported fully diluted
earnings per share.

3.       COMPREHENSIVE LOSS

         As of January 1, 1998, the Company 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 and six months ended June 30,
1999 amounted to $1,726,000 and $3,932,000, as compared to $5,443,000 and
$9,456,000 for the three and six months ended June 30, 1998.

5.       LEGAL PROCEEDINGS

         In September 1996, CardioGenesis Corporation ("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 the TMR and PMR lasers of CardioGenesis do not infringe this patent.
The Company filed a counterclaim alleging that all of the TMR and PMR lasers of
CardioGenesis 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 the TMR and PMR lasers of CardioGenesis
infringe the Company's German synchronization patent. The PLC patents at issue
in these lawsuits cover the Company's synchronization technology, a critical
factor in ensuring the safety of TMR and PMR procedures.

         In January 1999, the Company settled its outstanding patent
infringement litigation with CardioGenesis. Under the settlement, CardioGenesis
acknowledged 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 must 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 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 of damages in


                                      -7-





                                PLC SYSTEMS INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)


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. Two of these suits have been dismissed. The
Company moved to dismiss all of the remaining claims. On March 26, 1999, the
court issued an order dismissing some, but not all, of the remaining claims. The
Company has also been named as a defendant in a lawsuit filed in Massachusetts
Superior Court in September 1998. This suit seeks 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 Company cannot
make a meaningful estimate of the amount or range of loss that could result from
an unfavorable outcome of these lawsuits, but an unfavorable outcome could have
a material adverse affect on our business, financial position and results of
operations. The Company believes that it has valid defenses and continues to
vigorously defend itself in these matters.

         In August 1997, the Company received from the United States Securities
and Exchange Commission (the "Commission") an informal request for information
relating to the decision by the FDA advisory panel not to recommend approval of
The Heart Laser System in July 1997. The Company has responded and not received
any further communication from the Commission regarding this matter since June
1998.

         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 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. In October 1997, the French Ministry of
Health suspended commercial use of TMR devices in France. Foch Hospital is
seeking reimbursement of lease payments made for The Heart Laser System. The
Company intends to vigorously defend itself in this matter. This matter is in
the earliest stage of litigation and a meaningful estimate of the loss that
could result from this matter has not been made.

         The Company is not involved in any other litigation of a material
nature.

6.       EQUITY FINANCING

         On March 4, 1999, the Company announced that it had obtained a
provisional equity financing commitment of $8 million from a major institutional
investor. As of June 30, 1999, the Company had sold 532,908 shares of common
stock under this commitment, resulting in proceeds to the Company (net of all
issuance costs payable upon closing) of approximately $1,500,000. In July 1999,
the Company sold an additional 116,566 shares of common stock, pursuant to this
commitment resulting in net proceeds of approximately $ 400,000. This


                                      -8-



                                PLC SYSTEMS INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (Continued)


financing commitment expired on July 16, 1999.

         In July 1999, the Company sold 666,666 shares of common stock to
another institutional investor resulting in net proceeds to the Company of
approximately $1,900,000.

7.       LEASE RECEIVABLES

         The Company has entered into third-party financing alliances to provide
a broad array of lease financing alternatives to U.S. hospitals interested in
acquiring The Heart Laser System. The lease financing alternatives available are
expected to complement the Company's traditional placement and sales strategies.

         Under these agreements, the Company receives payment from the leasing
company equal to the present value of guaranteed minimum procedure 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 lease payments until such time as the Company
can legally isolate the lease receivables. For the six months ended June 30,
1999, the Company recognized product sales revenue and placement revenue of
$1,955,000 and $40,000, respectively, related to transactions under the
third-party financing alliances. 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 borrowings, respectively, are
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 Statement of Operations.

         In transactions where a sale has not occurred, the Company accounts for
the transaction as an operating lease. Guaranteed minimum procedure payments are
recorded as revenue as earned and included as a component of placement and
service revenue. The cash received from the leasing company is recognized as a
secured borrowing. Interest expense related to the secured borrowings are
recognized over time using the effective interest method and included in the
Statement of Operations as a component of interest expense.

and the Company's other filings with the Securities and Exchange Commission. 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. In placement
transactions, an installation fee is paid when The Heart Laser System is shipped
and the Company then receives a procedure fee per use. Typically, customers
commit to pay for a minimum number of procedures during the term of a placement
agreement. Sterile handpieces and other disposables are included in the
procedure fee. Revenues from these contracts are classified as placement fees.
The cost of The Heart Laser System, which is owned by the Company, is
depreciated over the term of the placement agreement.

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

         The Company entered into third-party financing alliances in order to
provide a broad array of lease financing alternatives to hospitals interested
in acquiring The Heart Laser System. The lease financing alternatives
available through these alliances are expected to complement the Company's
traditional placement and sales strategies. Under these agreements, the
Company obtains cash from the leasing company equal to the present value of
guaranteed minimum procedure payments due from the customer after customer
acceptance of The Heart Laser System.

RESULTS OF OPERATIONS

         Total revenues for the quarter ended June 30, 1999 were $3,492,000
an increase of $2,812,000 when compared to $680,000 for the quarter ended
June 30, 1998. Product sales for the quarter ended June 30, 1999 were
$2,685,000, an increase of $2,525,000 when compared to $160,000 for the
quarter ended June 30, 1998. The major factor in these increases is an
increase in the number of sales transactions. In the three months ended June
30, 1999, the Company recorded revenue on nine sales transactions. In the
1998 period, there were no sales transactions. During the second quarter of
1999, the Company recognized product sales revenue and placement revenue of
$1,287,000 and $20,000, respectively, related to transactions under the
third-party financing alliances.

         Total revenues for the six months ended June 30, 1999 were
$6,338,000, an increase of $4,713,000 when compared to $1,625,000 for the six
months ended June 30, 1998. Product sales for the six months ended June 30,
1999 were $4,844,000 an increase of $4,319,000 when compared to $525,000 for
the six months ended June 30, 1998. The major factor in these increases is an
increase in the number of sales transactions. In the six months ended June
30, 1999, the Company recorded revenue on thirteen sales transactions. In the
1998 period, there were no sales transactions. In addition, in January 1999,
the Company settled its outstanding patent dispute with CardioGenesis and
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. Included in product sales for the six months ended June 30, 1999
is the license fee associated with the above settlement. During the first six
months of 1999, the Company recognized product sales revenue and placement
revenue of $1,955,000 and $40,000, respectively, related to transactions
under the third-party financing alliances.

         Placement and service fees for the three and six months ended June
30, 1999 were $807,000 and $1,494,000, increases of $287,000 and $394,000
when compared with $520,000 and $1,100,000 for the same periods in fiscal
1998. In May 1997, the Health Care Financing Administration ("HCFA")
instituted a non-coverage policy for transmyocardial revascularization
("TMR") procedures performed on Medicare patients in the United States. The
HCFA announcement, coupled with delays in the FDA Pre-Market Approval ("PMA")
process, caused the Company to examine its contractual requirements during
1997 and amend substantially all of its placement contracts, temporarily
replacing contractual minimal billings with actual usage billings. Following
receipt of the PMA from the FDA on August 20, 1998, placement contracts that
provide for minimum billings were reinstated, and the Company has been
renegotiating those placement agreements that do not provide for minimum
billings following FDA approval. The 1999 period reflects revenue from
placement contracts with specified minimum billing reinstated following FDA
approval. The 1998 period reflects revenue from placement contracts with
actual usage billings.

         Total gross margin for the three and six month periods ended June 30,
1999 approximated 49% and 51% of revenues up from losses of 52% and 6% for the
comparable periods in fiscal 1998. In the 1998 periods, the Company did not
generate sufficient gross margin dollars to offset manufacturing variances,
resulting in negative gross margins. Gross margins improved as a result of an
increase in sales volumes which more than offset fixed manufacturing costs.

         Selling, general and administrative expenditures of $2,977,000 and
$5,619,000 for the three and six month periods ending June 30, 1999 decreased
25% and 20% when compared to fiscal 1998 expenditures of $3,944,000 and
$6,997,000. In April 1999, the Company restructured its


                                      -11-



workforce by eliminating 27 positions of the 91 positions within the Company as
of April 23, 1999. The 1999 periods reflect reduced headcount and compensation
and related benefits related to the reduced workforce, offset by related
severance costs associated with the reduction. The severance costs did not have
a material impact on the Company's results of operations.

         Research and development expenditures for the three and six months
ended June 30, 1999 were $573,000 and $1,621,000, decreases of 55% and 37% when
compared to spending of $1,274,000 and $2,565,000 for the comparable periods in
fiscal 1998. The decrease in 1999 compared to 1998 reflects the reduced demands
for clinical study compilation and data preparation following the FDA approval
for The Heart Laser(TM) System. In addition, in April 1999, the Company had a
reduction in its workforce. The 1999 periods reflect reduced headcount and
compensation and related benefits related to the reduced workforce.

         Other income of $125,000 and $132,000 for the three and six months
ended June 30, 1999 decreased $42,000 and $186,000 when compared to $167,000
and $318,000 for the comparable periods in fiscal 1998, primarily related to
less interest income as a result of lower cash balances in the 1999 period
when compared to the 1998 period.

         The Company incurred a net loss of $1,705,000 and $3,904,000 for the
three and six months ended June 30, 1999 when compared to net losses of
$5,402,000 and $9,338,000 for the comparable 1998 periods.

LIQUIDITY AND CAPITAL RESOURCES

         At June 30, 1999, the Company had cash and cash equivalents of
$3,982,000.

         Over the past two years, the Company has incurred significant operating
losses and utilized significant amounts of cash to fund operations. The Company
is reaching a critical stage in its growth as it transitions from a research and
development company to a commercial company with complete sales, marketing and
production capabilities. During this time the Company increased its overall
operating expenses and overhead to be positioned to further increase its sale
and production capabilities in anticipation of possible FDA approval. In order
to be adequately positioned to meet these demands, the Company obtained equity
financing. The Company continues to seek equity financing as its primary means
of funding operations during this transition.

         On March 4, 1999, the Company announced that it had obtained a
provisional equity financing commitment of $8 million from a major institutional
investor. The commitment contemplated the sale by the Company of up to $2
million in common stock during consecutive 20 day periods at prices based on the
trailing volume weighted average price of the common stock on the American Stock
Exchange on each day during such periods, less a seven percent discount.

         As of July 16, 1999, the Company had sold 649,474 shares of common
stock under this commitment, resulting in net proceeds to the Company of
approximately $1,900,000. The commitment expired on July 16, 1999. In July 1999,
the Company sold 666,666 shares of common stock to another investor resulting in
net proceeds of approximately $1,900,000. There can be no assurance that the
Company will be able to raise additional equity financing or that the Company
will maintain its eligibility to use Form S-3. To the extent that the Company
raises additional capital by issuing equity or convertible securities, ownership
dilution to the stockholders will result.

                                      -12-




         During the second half of 1998, the Company implemented a number of
programs to reduce its consumption of cash, including operating expense
reductions and the financing agreement with GE Capital, which enables the
Company to obtain an upfront cash payment on certain domestic transactions with
customers. While the Company is encouraged by the recent developments with
respect to FDA approval and the HCFA announcement that Medicare will provide
coverage, beginning July 1, 1999, for TMR procedures performed with devices
approved by the FDA, the historical absence of widespread reimbursement for the
TMR procedure by third party payers, principally Medicare, Medicaid, and private
health insurance plans, has limited demand for and use of The Heart Laser System
in the United States. Although Medicare reimbursement will begin in 1999 and
some private insurance plans have begun reimbursing health care providers for
TMR procedures, 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 of the Company has begun to implement a plan of appropriate
action steps to attempt to ensure that the Company has adequate sources of cash
to meet its working capital needs for at least the next twelve months. In March
1999, management of the Company received approval from the Board of Directors to
begin implementation of this action plan. The key elements of the plan are as
follows:

         -        Further operating expense reductions to eliminate certain
                  expenditures which are not critically essential to achieving
                  critical business objectives at this time (e.g., discretionary
                  spending, further development efforts).
         -        Strategic realignment of the Company's international sales
                  organization.
         -        Pursuit of strategic alternatives related to the Company's
                  domestic sales efforts that can help it further penetrate
                  existing markets.
         -        Pursuit of strategic financing alternatives including the sale
                  of debt or equity securities, strategic alliances, joint
                  ventures or by other means.

         On April 29, 1999, the Company announced a restructuring of the
Company to further reduce operating expenses and concentrate the Company's
resources on its sales efforts. The restructuring eliminated 27 positions of
the 91 positions within the Company as of April 23, 1999.

         As a result of implementing the above actions, management believes that
its existing cash resources and cash from operations will meet working capital
requirements over the next twelve months. However, unanticipated decreases in
operating revenues, increases in expenses or further delays in the process of
third party payers committing to provide reimbursement to healthcare providers
may adversely impact the Company's cash position and require further cost
reductions. 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.

         For the six months ended June 30, 1999, the Company incurred a loss of
$3,904,000, which resulted in the use of $2,622,000 to support operations. Cash
used for investing activities was $215,000, primarily related to investment on
fixed assets associated with the Company's placement contract activity. Cash
provided by financing activities was $1,824,000, including $1,525,000 in net
proceeds from the provisional equity financing commitment, $17,000 from the
exercise of stock options, and $334,000 from secured borrowings.


                                      -13-



         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

         The Year 2000 problem is the result of computer programs that use two
digits rather than four to define the applicable year. On January 1, 2000,
computer equipment and programs that have time-sensitive software may not be
able to distinguish whether "00" means 1900 or 2000. This could cause a major
system failure or could create erroneous results. The Company could be unable to
process transactions, send invoices, or engage in similar business activities.
The Company may also be vulnerable to other companies' Year 2000 issues.

         In 1998, the Company formed a task force to determine what if any Year
2000 compliance issues the Company faces. The task force has developed and
implemented a Year 2000 readiness plan that defines compliance and sets critical
milestones to identify any deficiencies and correct them. The task force
identified three basic operational areas that have been and will continue to be
examined:

         -        Products - products the Company currently sells, products the
                  Company sold previously, and products of the Company's most
                  significant suppliers;
         -        Business Systems - computer hardware and software used to
                  operate the Company's business, including purchasing,
                  manufacturing, sales and finance; and
         -        Peripherals - the Company's telephone, e-mail, security and
                  shipping systems.

         In 1998, The Heart Laser System was tested and is believed to be Year
2000 compliant in all material respects. In addition, the Company has purchased
and implemented new enterprise resource planning system software that the vendor
has represented is Year 2000 compliant. This new software system has replaced
substantially all of the Company's previous financial software systems. Current
estimates of the impact of the Year 2000 problem on the Company's operations and
financial results do not include costs and time that may be incurred as a result
of vendor or customer failures to become Year 2000 compliant, but no significant
costs have been identified to date.

         Despite investigation and testing by the Company and its business
partners, the Company's products and systems may contain errors or defects
associated with Year 2000 date functions. The Company believes that its new
enterprise resource planning software substantially addresses its material Year
2000 risks; however, the Company is continuing to test its secondary systems and
investigate third party compliance efforts. In a worst case scenario, known and
unknown errors and defects that could affect the operation of our products or
systems could result in:

         -        delay or loss of revenue;
         -        cancellation of customer contracts;
         -        increased service and/or warranty costs;
         -        increased litigation costs;
         -        diversion of product development and personnel resources; and
         -        damage to our reputation.

         Furthermore, the Company has not developed a Year 2000 contingency plan
to address any

                                      -14-



failure of our Year 2000 compliance review to identify and
correct significant Year 2000 risks. Development of contingency plans is in
progress and will continue during calendar year 1999. Such plans could include
stockpiling inventory parts and raw materials, accelerating replacement of
affected equipment or software, using back-up equipment and software, developing
temporary manual procedures to compensate for system deficiencies, and
identifying alternative Year 2000 capable suppliers. The Company cannot be sure
that such contingency plans will adequately address the year 2000 problem. Any
of these occurrences could have a material adverse effect on our business,
financial condition and results of operations.

         Unanticipated decreases in operating revenues or increases in expenses
may adversely impact the Company's cash position. 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.

         The Company believes that operating losses are likely prior to such
time, if ever, as third party payers agree to reimburse health care providers
for use of The Heart Laser System. The Company must also convince health care
professionals, third party payers and the general public of the medical and
economic benefits of The Heart Laser System. No assurance can be given that the
Company will be successful in marketing The Heart Laser System or that the
Company will be able to operate profitably on a consistent basis.

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 in the United
States and sells the products. 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 exchanges rates between the U.S. dollar and 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 is a net
receiver of currencies other than the U.S. dollar and, as such, benefits from a
weaker dollar, but is adversely affected by a stronger dollar relative to major
currencies worldwide. The Company's exposures are not 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.

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

           On May 24, 1999, the Company held its Annual General Meeting of
           Stockholders to vote on the following proposals:

           1.         To elect two members of the Board of Directors for a three
                      year term. Nominees for Director were: (a) H.B. Brent
                      Norton; and (b) Roberts A. Smith ("Prosposal No. 1");
           2.         To consider and vote upon a resolution ratifying the
                      adoption of By-Law No. 1 ("Proposal No. 2");
