              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 1999
                                   (UNAUDITED)
               (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The interim financial information is unaudited. In the opinion of management of
EndoSonics Corporation ("EndoSonics" or the "Company"), the condensed
consolidated financial statements included in this report reflect all
adjustments necessary, consisting only of normal recurring adjustments, to
present fairly the Company's consolidated financial position at March 31, 1999
and the consolidated results of its operations and cash flows for the three
month periods ended March 31, 1999 and 1998. Results for the interim periods are
not necessarily indicative of consolidated results to be expected for the entire
fiscal year. These financial statements should be read in conjunction with the
Company's audited financial statements for the year ended December 31, 1998,
contained in the Company's Annual Report on Form 10-K.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of EndoSonics and its
subsidiaries. (EndoSonics and its subsidiaries are collectively referred to
hereinafter as "the Company"). All significant intercompany accounts and
transactions have been eliminated. Investments in unconsolidated subsidiaries,
and other investments in which the Company has a 20% to 50% interest or
otherwise has the ability to exercise significant influence, are accounted for
under the equity method.

RECLASSIFICATIONS

Certain reclassifications have been made to the prior period balances to conform
with current period presentations.

INVESTMENTS

In accordance with SFAS 115, the Company has classified its investment portfolio
as available-for-sale. Unrealized gains (losses) on available-for-sale
securities are recorded as a separate component of other comprehensive income.

2. INVENTORIES

Inventories are stated at the lower of cost, determined on a first in, first out
(FIFO) cost basis, or market value. Inventories consist of the following:

</TABLE>


3. COMPUTATION OF NET INCOME (LOSS) PER SHARE

Net income (loss) per share is computed using the weighted average number of
shares of common stock outstanding. Common equivalent shares from stock options
and warrants are excluded from the computation of net loss per share because
their effect is antidilutive. Conversely, common equivalent shares from stock
options are included in the computation of net income per share to the extent
that the impact is dilutive.

At March 31, 1999 and December 31, 1998, the Company had outstanding options to
purchase 3,564,714 and 3,744,030 shares of common stock, respectively (with
exercise prices ranging from $0.32 to $16.50) and outstanding warrants to
purchase 12,304 shares of common stock (with exercise prices from $11.76 to
$12.55). If exercised, these options could potentially dilute basic earnings per
share in future periods.

4. COMPREHENSIVE INCOME (LOSS)

The following table sets forth the computation of comprehensive income:

6. STOCK REPURCHASE

The Board of Directors has authorized a stock repurchase program whereby the
Company may repurchase up to 1.7 million shares of its common stock from
time-to-time in the open market or private transactions. As of December 31,
1998, the Company had repurchased 860,000 shares of its common stock on the open
market at an aggregate cost of approximately $4,839. During the quarter ended
March 31, 1999, the Company repurchased an additional 110,000 shares of its
common stock on the open market at an aggregate cost of approximately $938.
Also, during the quarter ended March 31, 1999, 28,520 shares of common stock
held in treasury were re-issued to participants of the Company's Employee Stock
Purchase Plan at prices ranging from $4.0375 to $7.3313 per share. As a result,
a total of 941,480 shares were held in treasury at March 31, 1999 at an

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

This Quarterly Report on Form 10-Q contains forward looking statements. The
Company's business is subject to risks and uncertainties and the Company's
actual results may differ significantly from the results discussed in the
forward looking statements. Factors that might cause such a difference include,
but are not limited to, the Company's ability to transition to new distribution
arrangements in Europe and North America, the introduction of new products, FDA
approval of new products and changes in regulatory requirements and third-party
reimbursement policies. For a discussion of these and other factors, please see
"Risk Factors" in the Company's Annual Report on Form 10-K (starting at page 20)
for the fiscal year ended December 31, 1998.

INTRODUCTION

     Since its inception in 1984, EndoSonics has been engaged primarily in the
research and development of products for the diagnosis and treatment of
cardiovascular disease. Since 1991, a majority of the Company's net revenue has
been derived from sales of its IVUS imaging systems and catheters.

     The Company markets and distributes its IVUS imaging products in the United
States, Europe and Japan through relationships with strategic partners, certain
other distributors and, to a lesser extent, through a direct sales force. In
February 1996, EndoSonics and Cordis entered into the Exclusive Distribution
Agreement pursuant to which Cordis was granted the exclusive right 



                                       8
<PAGE>   9

to distribute EndoSonics' IVUS imaging products for coronary applications in
North America, Europe, Africa and the Middle East. Cordis was obligated during
each year of the Exclusive Distribution Agreement to use reasonable efforts to
purchase certain minimum annual amounts of products from EndoSonics. In
connection with the execution of the Exclusive Distribution Agreement, the
Company issued 350,877 shares of its Common Stock to Cordis in a private
placement transaction for an aggregate purchase price of approximately $5.0
million. The Company has since registered the shares of Common Stock issued to
Cordis. The exclusive Distribution Agreement was terminated in April, 1998.
EndoSonics and Cordis entered into a Transition Agreement in April, 1998 which
provided for Cordis to maintain significantly reduced distribution rights. These
distribution rights terminated in March, 1999.

    In March 1997, the Company and Johnson & Johnson Medical K.K. ("JJMKK"),
entered into a distribution agreement whereby JJMKK was granted exclusive right
to distribute EndoSonics IVUS imaging products for coronary applications in
Japan. The agreement contained similar terms as the Exclusive Distribution
Agreement between Cordis and EndoSonics. The agreement was amended in December
1998 to extend the agreement through December 1999.

    In April 1997, the Company and Johnson & Johnson, Professional Group - Latin
America ("J & J Medical-LA"), entered into a distribution agreement whereby J &
J Medical-LA was granted exclusive rights to distribute EndoSonics IVUS imaging
products for coronary applications in certain countries of Latin America. The
agreement contained similar terms as the Exclusive Distribution Agreement
between Cordis and EndoSonics. The agreement was amended in December 1998 to
extend the agreement through December 2000.

    In July, 1998, the Company announced that it has agreed in principal to
enter into a strategic relationship with Fukuda which includes an equity
investment and research and development funding totaling $13 million in
EndoSonics by Fukuda. Approximately $8.4 million of Fukuda's investment was for
the purchase of newly issued EndoSonics common stock. The balance of the
investment will fund certain research and development/technical assistance
programs for products intended for the Japanese market which will be distributed
by Fukuda. The funding will occur over a two-year period commencing in August,
1998.

    In December 1998, the Company and JOMED N.V., ("JOMED") entered into an
agreement for exclusive distribution of certain EndoSonics products into
specified European and Middle Eastern countries. Also in December, EndoSonics
and JOMED entered into an IVUS-guided stent delivery system agreement which
calls for the development of a JOMED balloon and stent incorporated into a
modular EndoSonics IVUS catheter. Under the agreement, EndoSonics will supply
subassemblies to JOMED who will complete the manufacturing process and
distribute the resulting product in the territory which is defined as certain
European and Middle Eastern countries. In certain countries within the
territory, EndoSonics may distribute exclusively or jointly with JOMED.

     Radiance Medical Systems, Inc., formerly a majority-owned subsidiary of the
Company, designs, develops, manufactures and markets catheters used to treat
certain vascular diseases. Radiance's catheters are used in conjunction with
angioplasty and other interventional procedures such as vascular stenting and
drug delivery. Radiance completed its initial public offering in June of 1996
and, as a result, its assets, liabilities and results of operations are no
longer included in the Company's 



                                       9
<PAGE>   10

consolidated financial statements. At March 31, 1999, the Company held
approximately 15% of the outstanding shares of the Common Stock of Radiance and
accounted for its investment on the cost method.

     The Company's business strategy includes acquiring related businesses,
products or technologies. On July 23, 1997, the Company acquired Cardiometrics
through the merger of a wholly owned subsidiary of the Company with and into
Cardiometrics, with Cardiometrics surviving as a wholly owned subsidiary of the
Company.

     Cardiometrics develops, manufactures, and markets intravascular medical
devices to measure blood flow impairment caused by coronary artery disease.
Cardiometrics' initial products, the FloWire(TM) Doppler guide wire and FloMap
ultrasound instrument, represent an advance in functional testing of blood flow
impairment, enabling cardiologists to evaluate the appropriateness of
angioplasty interventions and assess post-procedural results directly in the
cardiac catheterization laboratory. Clinical experience demonstrates that the
measurement of blood flow impairment downstream from (distal to) an obstruction,
which Cardiometrics calls functional angiometry, provides information to improve
the quality of patient care and procedure outcomes in the diagnosis and
treatment of cardiovascular disease. The FloWire(TM)/FloMap(TM) systems has
received clearance from the FDA and many corresponding European and Pacific Rim
regulatory agencies. Cardiometrics has also developed the WaveWire(TM)/WaveMap
intracoronary blood pressure measurement system, which was first used in a
clinical case in Europe in December 1996. Cardiometrics received a 510(k)
approval in August 1997 for the WaveWire(TM)/WaveMap(TM) System, and commenced
shipment to United States customers in 1998.

     On August 5, 1998, the Company acquired Navius Corporation, a San Diego
based, privately-held developer of angioplasty balloons, stents, intravascular
radiation devices and other medical products. Navius' results of operations are
combined with those of the Company since the date of the acquisition.

     The Company expects that it may pursue additional acquisitions in the
future. Any future acquisitions may result in potentially dilutive issuances of
equity securities, the write-off of in-process research and development, the
incurrence of debt and contingent liabilities and amortization expenses related
to intangible assets acquired, any of which could materially adversely affect
the Company's business financial condition and results of operations. In
particular, if the Company is unable to use the "pooling of interests" method of
accounting, the Company will be required to amortize any intangible assets
acquired in connection with any additional acquisitions over the useful lives of
such assets. Additionally, unanticipated expenses may be incurred relating to
the integration of technologies and research and development, and administrative
functions. Any acquisition will involve numerous risks, including difficulties
in the assimilation of the acquired company's employees, operations and
products, uncertainties associated with operating in new markets and working
with new customers, the potential loss of the acquired company's key employees
as well as the costs associated with completing the acquisition and integrating
the acquired company.

RESULTS OF OPERATIONS

FIRST QUARTER OF 1999 COMPARED TO THE SAME PERIOD IN 1998


                                       10
<PAGE>   11



Total Revenue. Total revenue increased 34% to $12.1 million for the first
quarter of 1999, from $9.0 million in the first quarter of 1998. Revenues for
the IVUS business increased by 47%, or $2.7 million due primarily to an increase
in sales in Europe over 1998 levels due in part to the Company's strategic
alliance with JOMED BV. Revenues for the Cardiometrics business decreased by 14%
or $0.4 million due to a decline in shipments of FloMap and WaveMap products.
This decline was not fully offset by the increase in FloWire and WaveWire
shipments. Export sales comprised approximately 68% of total revenues in first
quarter of 1999 as compared to 73% in the first quarter of 1998. The Company
expects that export sales will continue to represent a substantial portion of
the Company's revenue in future periods.

Cost of Sales. Cost of sales as a percentage of total revenues decreased to 49%
for the first quarter of 1999 from 55% for the first quarter of 1998. Cost of
sales as a percentage of total revenues decreased due in part to higher average
selling prices of IVUS products resulting from an improved geographical mix as
well as the Company's decision to transition from distribution relationships to
a direct sales approach in certain geographical regions. In addition, in 1998
cost of sales included certain start-up costs related to the ramp up of
manufacturing of Company's WaveWire catheter. These costs were not present in
1999. Due to the uncertainty associated with continued improvements in the
efficiency of the Company's manufacturing process and the impact of increasingly
competitive pricing, there can be no assurance that the Company's gross profit
margin will be maintained or continue to improve in future periods.

Research, Development, and Clinical. Research, development and clinical expenses
decreased by $0.2 million to $1.6 million for the first quarter of 1999 from
$1.8 million for the first quarter of 1998. As part of a strategic alliance with
Fukuda, the Company recognized approximately $0.5 million in research and
development funding, which offset certain first quarter expenditures. Excluding
the reimbursement from Fukuda research and development expenses totaled
approximately $2.1 million, which represents an increase of $0.3 million or 17%
from the first quarter of 1998. The increase is due primarily to Navius'
research and development expenses which are included in the first quarter 1999
operating results as a consequence of the Company's August 1998 acquisition of
Navius.

Marketing and Sales. Marketing and sales expenses increased to $2.3 million in
the first quarter of 1999 from $2.1 million in the first quarter of 1998. The
increase is due to increased staffing and marketing programs related to staffing
a direct sales force in the United States and Germany. The increased expense was
offset by a 34% increase in revenues. As a result marketing and sales expense as
a percentage of revenues decreased to 19% in the first quarter of 1999 as
compared to 23% for the same period in 1998.

General and Administrative. General and administrative expenses decreased by
$0.6 million dollars or 41% to $0.9 million dollars for the first quarter of
1999 compared to $1.6 million dollars for the first quarter of 1998. The
reduction is due primarily to a reduction in legal expenses related to patent
litigation which was ongoing in the first quarter of 1998.

Amortization of Intangibles. Amortization of intangibles increased to $0.5
million in the first quarter of 1999 from $0.3 million in the first quarter of
1998. The amortization relates to goodwill and other intangible assets acquired
in the acquisition of Navius in August 1998 and

Cardiometrics in July 1997. Goodwill and other intangibles are being amortized
over periods ranging from three-to-nine years.

Equity in Loss of Radiance Medical Systems, Inc. There was no equity in net loss
of Radiance Medical Systems, Inc. (RADX) in the first quarter of 1999, as
compared to $0.2 million in the first quarter of 1998. Since February 1998, the
Company's ownership in RADX has been less than 20%.

Other Income. Other income decreased to $0.3 million in the first quarter of
1999 as compared to $0.8 million in the first quarter of 1998. In the first
quarter of 1998 the Company recognized a gain of $0.6 million from the sale or
Radiance Medical Systems, Inc. (RADX) common stock. The Company did not sell any
RADX common stock in the first quarter of 1999.

Net Income (Loss). Net income was $1.2 million , or $0.07 per share, in the
first quarter of 1999 as compared to a net loss of ($1.1) , or ($0.07) per
share, in the first quarter of 1998.

LIQUIDITY AND CAPITAL RESOURCES

On March 31, 1999, the Company had cash and equivalents of $2.1 million,
short-term investments of $21.2 million and no borrowings or credit facilities.
Net cash provided by (used in) operations was ($1.6) million in the first
quarter of 1999 as compared to $2.0 million in the first quarter of 1998. The
deterioration is due primarily to an increase in accounts receivables and other
current assets.

Net cash provided by (used in) investing activities was ($6.0) million in the
first quarter of 1999 as compared to $6.1 million in the first quarter of 1998.
The decrease is due primarily to the purchase of $10 million in short-term
investments and the acquisition of $1.2 million in property, plant and equipment
in the first quarter of 1999.

Net cash provided by financing activities was $1.2 million in the first quarter
of 1999 as compared to $0.1 in the first quarter of 1998. The increase is due
primarily to the $2.1 million in proceeds from the exercise of common stock
options, offset partially by the acquisition of $0.9 million in treasury stock.

The Company anticipates using cash resources primarily for capital expenditures,
product development, sales and marketing efforts and working capital purposes.
The Company believes that its existing cash, cash equivalents, and short-term
investments as of March 31, 1999 will be sufficient to meet the Company's
operating expenses and capital requirements through 1999. However, there can be
no assurance that the Company will not be required to seek other financing or
that such financing, if required, will be available on terms satisfactory to the
Company.

IMPACT OF YEAR 2000

The Year 2000 Issue is the result of computer programs being written using two
digits rather than four to define the applicable year. Any of the Company's
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. 



                                       12

This could result in a system failure or miscalculations causing disruptions to
operations, including, a temporary inability to process transactions, send
invoices, or engage in similar normal business activities. Should any of these
disruptions occur, the financial impact on the Company is unknown.

The Company has completed an assessment and will have to modify or replace
certain portions of its existing software in order for its computer systems to
function properly with respect to dates in the year 2000 and thereafter.
However, independent of the Year 2000 Issue, the Company has plans to replace
the majority of its existing computer programs with an integrated,
enterprise-wide software platform. The Company has identified a software program
which meets the Company's operational needs and is also Year 2000 compliant. The
Company believes that the new software can be installed and tested with regards
to the Year 2000 Issue by September, 1999. It is expected that the cost of the
new software, installation, and testing will be between $0.5 million and $1.0
million, the majority of which would be capitalized. In the event that the new
software does not function properly with regard to the Year 2000, and an
adequate solution is not readily available, the Company's believes that it can
make the necessary modifications, (consisting primarily of software version
upgrades), to its current computer programs in order to make them Year 2000
compliant.

It is anticipated that the Year 2000 project will be completed not later than
September, 1999, which is prior to any anticipated impact on the Company's
operating systems. The Company believes that with the planned software
conversion or with modifications to the existing software, the Year 2000 Issue
will not pose a significant operational problem. However, if such modifications
are not completed timely, the Year 2000 Issue could have a material impact on
the operations of the Company. Likewise, if any of the Company's key suppliers,
vendors or customers experience a prolonged business interruption as a result
of the Year 2000 Issue, it could have a material impact on the operations of
the Company.

The costs of the project and the date on which the Company believes it will
complete the Year 2000 modifications are based on management's best estimates,
which assume certain future events, including the continued availability of
certain resources. However, there can be no guarantee that these estimates will
be achieved and actual results could differ materially from those anticipated.
Specific factors that might cause such material differences include, but are not
limited to, the availability and cost of personnel trained in this area, the
effectiveness of the new software and, if necessary, the upgrades received from
the Company's software vendors at addressing the Year 2000 Issue and similar
uncertainties.
